TY - JOUR A1 - Özsoy, Onur A1 - Iefremenko, Kateryna A1 - Schroeder, Christoph T1 - Shifting and expanding clause combining strategies in heritage Turkish varieties JF - Languages N2 - Turkish is a language described as relying predominantly on non-finite subordination in the domain of clause combining. However, there are also strategies of finite subordination, as well as means of syndetic and asyndetic paratactic clause combining, especially in the informal settings. Clause combining is and has been one of the focal points of research on heritage Turkish (h-Turkish). One point is particularly clear: In comparison with the monolingual setting, finite means of clause combining are more frequent in h-Turkish in Germany, the U.S., and the Netherlands, while non-finite means of clause combining are less frequent. Overall, our results confirm the findings of earlier studies: heritage speakers in Germany and the U.S. prefer paratactic means of clause combining using connectors, as opposed to monolingual speakers. Our results also reveal that age (adolescents vs. adults) and register (informal vs. formal) significantly modulate the use of connectors. Moreover, we find that the shift in preferences in means of clause combining triggers an expansion in the system of connectors and leads to the development of new narrative connectors, such as o zaman and derken. The system of syndetic paratactic clause combining is expanding in heritage Turkish. This expansion calls for multifaceted modeling of change in heritage languages, which integrates language-internal factors (register), dynamics of convergence with the contact languages, and extra-linguistic factors (age and language use).

T2 - Responsible design, implementation and use of information and communication technology N2 - Increasingly, research attention is being afforded to various forms of problematic media use. Despite ongoing conceptual, theoretical, and empirical debates, a large number of retrospective self-report scales have been produced to ostensibly measure various classes of such behaviour. These scales are typically based on a variety of theoretical and diagnostic frameworks. Given current conceptual ambiguities, building on previous studies, we evaluated the dimensional structure of 50 scales targeting the assessment of supposedly problematic behaviours in relation to four technologies: Internet, smartphones, video games, and social network sites. We find that two dimensions (‘compulsive use’ and ‘negative outcomes’) account for over 50% of all scale-items analysed. With a median of five dimensions, on average, scales have considered fewer dimensions than various proposed diagnostic criteria and models. No relationships were found between the number of items in a scale and the number of dimensions, or the technology category and the dimensional structure. The findings indicate, firstly, that a majority of scales place an inordinate emphasis on some dimensions over others and, secondly, that despite differences in the items presented, at a dimensional level, there exists a high degree of similarity between scales. These findings highlight shortcomings in existing scales and underscore the need to develop more sophisticated conceptions and empirical tools to understand possible problematic interactions with various digital technologies.

Exercise in the heat has been shown to further increase accumulation of RONS in systemic circulation; however, a high antioxidative response or heat acclimatization mechanisms could attenuate this response. In a previous study, we found reduced RONS concentrations in trained athletes following strenuous cycling in the heat. Therefore, this secondary analysis assessed whether these reduced RONS serum concentrations are induced by an increased serum antioxidant capacity. Methods: Twelve male cyclists (V?O2peak: 60 +/- 4 ml center dot kg-1 center dot min-1) completed a 60-minute constant workload trial (55% peak power output, ambient temperature 30.4 +/- 0.6 degrees C) with and without ice vest in a randomized order. The core body temperature (Tcore) was measured by an ingestible capsule. Blood samples were collected before and after each trial to determine superoxide dismutase (SOD) and catalase (CAT) activity, total antioxidant capacity (TAC) and RONS. Due to the absence of between-group differences, data of both conditions were pooled. Results: Tcore statistically increased (p < 0.001) over the experimental trials (+6.0 +/- 1.6%, effect size (ES) = 5.6). Concentrations of RONS (-17.2 +/- 15.5%, p < 0.001, ES = 1.0) and TAC (-8.9 +/- 22.9%, p = 0.04, ES = 0.7) statistically decreased, while the activity of CAT (+15.5 +/- 84.0%, p = 0.90, ES = 0.04) and SOD (+9.2 +/- 58.7%, p = 0.98, ES = 0.01) remained unchanged. Conclusions: Reduced serum RONS concentrations after strenuous cycling in the heat were not associated with upregulation of serum antioxidant capacity in trained athletes. The prooxidant-antioxidant balance may rather be regulated at a myocellular level and should be further assessed in future studies.

In systems like self-assembled monolayers or micelles, azobenzene chromophores may interact with each other, which gives rise to the emergence of exciton states. Here, using first-principles calculations, we investigate how conformational disorder (induced, e.g., by thermal fluctuations) affects localization of these states, on an example of an H-type azobenzene tetramer. We find that conformational disorder leads to (partial) exciton localization on a single-geometry level, whereas ensemble-averaging results in a delocalized picture. The pi pi* and n pi* excitons at high and low temperatures are discussed.

However, they are mostly limited to one-shot stylizations concerning the interactive adjustment of style elements. In particular, the expressive control over stroke sizes or stroke orientations remains an open challenge. To this end, we propose a novel stroke-adjustable fast style transfer network that enables simultaneous control over the stroke size and intensity, and allows a wider range of expressive editing than current approaches by utilizing the scale-variance of convolutional neural networks. Furthermore, we introduce a network-agnostic approach for style-element editing by applying reversible input transformations that can adjust strokes in the stylized output. At this, stroke orientations can be adjusted, and warping-based effects can be applied to stylistic elements, such as swirls or waves. To demonstrate the real-world applicability of our approach, we present StyleTune, a mobile app for interactive editing of neural style transfers at multiple levels of control. Our app allows stroke adjustments on a global and local level. It furthermore implements an on-device patch-based upsampling step that enables users to achieve results with high output fidelity and resolutions of more than 20 megapixels. Our approach allows users to art-direct their creations and achieve results that are not possible with current style transfer applications.

Both the negotiation and implementation of digitalization policy presents a challenge for all levels of government, requiring extensive coordination efforts. In general, there are conflicting views if more centralized or decentralized policy processes are more effective for coordination—a tension further exacerbated in the context of digitalization policy within multilevel systems, where the imperative of standardization collides with decentralization forces inherent in federalism. Based on the analysis of expert interviews (n = 29), this chapter examines how digitalization policy in the context of the German federal intergovernmental relations context is located and negotiated, and how this relates to local policy implementation. Focusing on the decentralized German tax administration as a case study, the analysis reveals a shift from a conflicted to a multi-layered policy process, underpinned by a mechanism of “concentration without centralization.” Strategic and operational competencies are bundled in an institutionalized and legally regulated network for digitalization to achieve necessary standardization of digital infrastructure. Furthermore, the research emphasizes the influence of intergovernmental relations on local implementation and the associated challenges and opportunities.

Local policymakers must coordinate a wide range of actors, among them sub-municipal administrative units and neighbouring administrations, in order to ensure legitimate, socially accepted and effective policy. The study examines, from a comparative perspective, how intergovernmental relations (IGR) play out in the formulation and implementation of climate strategies in the metropolitan areas of Berlin and Paris. Embedded in different institutional contexts, both cities followed a trajectory initiated by relatively centralized strategy formulation with an ongoing shift towards more decentralized and coordinated intergovernmental approaches with their respective district administrations. In terms of horizontal IGR, Berlin took a decoupled approach with limited coordination with the state of Brandenburg, whereas Paris was much more closely integrated with its surrounding areas through the inter-municipal metropolis of Greater Paris. Institutional capacity, multilevel coordination and participation demands are identified as three challenges for the existing IGR structures. Addressing these challenges places significant strains on local administrative capacity. The findings highlight the limitations of centralized approaches to IGR at the local level and the importance of aligning the distribution of functional responsibilities with the rights of consultation and participation in climate policy formulation processes.

Within the research strand of intergovernmental relations (IGR), the focus has been on executive actors and governmental decision-makers, resulting in an underexposure of the role of public administration, known as inter-administrative relations (IAR). Against this backdrop, we aim to remedy some of the deficits in IGR research by (1) adopting an explicit IAR perspective which systematically addresses the role of local governments; (2) including a comparative dimension in IAR research that accounts for different administrative ‘starting conditions’ in European countries; and (3) using the policy area of migrant integration as a case in point to empirically investigate developments of institutional convergence and divergence in IAR patterns. It is argued that the coordination of migrant integration in the three countries examined has moved towards more intergovernmental coordination, on the one hand, and that the role of municipalities in this context has been enhanced—varying degrees of (de-)centralization notwithstanding. While certain convergent patterns of inter-governmental coordination have become apparent during the migration crisis, historical path dependencies and administrative cultures still appear to be factors that influence institutional development.

Focusing on the crises arising from the Covid-19 pandemic, climate change, surges in migration, and the resurgence of regional nationalist movements, it explores the shifting power balances within intergovernmental relations’ systems. The book takes a comparative analytical perspective on how intergovernmental relations are changing across Europe, and how central governments have responded to coordination challenges as recent crises have disrupted established service delivery chains and their underpinning political and bureaucratic arrangements. It also examines the relationship between recent crises and the sub-national resurgence of territorial politics in many European countries. The book will appeal to those with interests in public administration, sub-national governance and European politics.

A1 - Holmberg, Christine T1 - A theory of change of an innovation for therapeutic care and meaningful living in a German nursing home JF - BMC geriatrics N2 - Background: Demographic changes are leading to growing care needs of older people and creating a challenge for healthcare systems worldwide. Nursing homes (NHs) need to provide care for growing numbers of residents while ensuring a high-quality care. We aimed to examine an innovative NH in Germany and apply a theory of change (ToC) approach to develop a best practice model (BPM) for therapeutic care in NHs. Methods: A multimethod qualitative study conducted from February to July 2021 in Germany involved interviews with 14 staff members of an innovative NH and 10 directors and care managers of other NHs. The interview guidelines included questions on nursing practices, infrastructure, resources, interprofessional collaboration, and working culture. Additional material on the participating NH (website, promotion videos, newsletters, care documentation) were collected. Contextual literature on NH culture and therapeutic care in Germany, ToC methodology, and NH culture change were reviewed. Following a question-focused analysis of all material, we generated a ToC model towards a BPM of therapeutic care and meaningful living in NHs. Results: were verified in interdisciplinary team meetings, with study participants and other stakeholders to establish consensus. Results The participating NH's care concept aims to improve residents' functional abilities and wellbeing as well as staff members' job satisfaction. Central components of their approach include therapeutic elements such as music and movement in all nursing activities, multidisciplinary collaboration, a broad therapy and social activity offer, the continuation of therapy in everyday activities, a focus on individual life history, values, needs, and skills, social integration into the regional community, and the creation of a meaningful living environment for residents and staff. Conclusion: The BPM we developed shows how a meaningful living environment can be created through therapeutic care and integrative activities. The ToC sheds light onto the contextual factors and cultural values which should be considered in the development of NH interventions. Research on not only biomedical aspects, but also psychosocial dynamics and narrative co-constructions in nursing practice should inform NH innovations. The ToC also highlights the importance of developing adequate political frameworks and infrastructures for implementing such innovative practices on a larger scale.

In particular, the fact that Alevism is a closed society due to the pressure they have experienced throughout history has prevented them from being perceived correctly. As such, it is seen that there are many misconceptions about Alevis and their rituals that do not match the reality but are accepted as correct by the society. Due to the lack of communication that could not be developed through this "unknown" in the historical process, Alevi-Sunni relations have always been open to manipulations. As a matter of fact, it is seen that Alevis' relations with Islam, the Djem ceremonies that form the basis of Alevism, and the content of Djem ceremonies have always remained a mystery to Sunnis. Unfortunately, this misperception also reflected negatively on the communication between the two groups. As it is known, if stereotypes arise when there is incorrect information about the target group, the best way to correct them is to create common contact environments that will bring individuals to the right information. Here in this article, the unknown Djem ritual and especially the Qur'anic verses that they refer to during the Djem ceremonies are discussed.

However, measuring particulate matter's mass and number concentrations in harsh environments poses great analytical constraints. The presented approach comprises a comprehensive set of light-and imaging-based techniques, all contactless, in-line, and real-time. It includes, but is not limited to, stroboscopic imaging, laser-induced breakdown spectroscopy (LIBS) and laser-induced incandescence (LII). Stroboscopic imaging confirmed the particles sphericity and was used to measure the particle number density. A phase-selective LIBS setup with low fluence and 500 Hz repetition rate was used to classify each particle with a single-pulse and in real time. Simultaneously, the created plasma was captured by CCD imaging to determine the detection volume and hit rate of the LIBS setup. Both data sets combined were converted to a particle number density, which was consistent with the particle number density of the stroboscopic measurements. Furthermore, using a photodiode and microphone in parallel to the LIBS setup allowed for the photoacoustic normalization of the spectral line intensity at the laser repetition rate of 500 Hz. This was done as a partial photoacoustic normalization method with the cut-off based on the coefficient of variation (CV), reducing it by 25%. Aside from that photodiode and microphone were proven to be valuable event counting with the advantage of the less spatially constricted. A second laser setup was used for laser -induced incandescence (LII) making it possible to classify the particles based on their incandescence tendency. Given its larger probing volume, LII could be employed at very low particle number densities. With respect to the current literature, this is the first approach of using LII as an in-line, real-time analytical technique for the compositional classification of metal-bearing aerosols.

Based on the theory of situational strength, we investigated how contextual and person-related factors influence workers’ adaptation in a two-worker position routine. Contextual factors, like retrieval cues (Study 1), time pressure (Study 2), and convenience (Study 3), were varied. Person-related factors included retentivity, general and routine-specific self-efficacy, and perceived adaptation costs. Dependent variables included various error types and production time before and after adaptation. In each study, 148 participants were trained in a production routine at t1 and executed an adapted routine at t2, one week later. Repeated measures ANOVA for performance at t1 and t2, and MANOVA for performance at t2, revealed that time increased for all groups at t2. For participants in Studies 1 & 2, error rates remained consistent. Retentivity significantly impacted errors at both t1 and t2, emphasising that routine changes in a ‘running business’ take time, regardless of contextual factors.

Consequently, many algorithms have been developed for the automatic detection of such anomalous patterns. The enormous number of approaches (i.e., more than 158 as of today), the lack of properly labeled test data, and the complexity of time series anomaly benchmarking have, though, led to a situation where choosing the best detection technique for a given anomaly detection task is a difficult challenge. In this demonstration, we present TIMEEVAL, an extensible, scalable and automatic benchmarking toolkit for time series anomaly detection algorithms. TIMEEVAL includes an extensive data generator and supports both interactive and batch evaluation scenarios. With our novel toolkit, we aim to ease the evaluation effort and help the community to provide more meaningful evaluations.

ER is typically employed as an expensive cleaning step on the entire data before consuming it. Yet, determining which entities are useful once cleaned depends solely on the user's application, which may need only a fraction of them. For instance, when dealing with Web data, we would like to be able to filter the entities of interest gathered from multiple sources without cleaning the entire, continuously-growing data. Similarly, when querying data lakes, we want to transform data on-demand and return the results in a timely manner-a fundamental requirement of ELT (Extract-Load-Transform) pipelines. We propose BrewER, a framework to evaluate SQL SP queries on dirty data while progressively returning results as if they were issued on cleaned data. BrewER tries to focus the cleaning effort on one entity at a time, following an ORDER BY predicate. Thus, it inherently supports top-k and stop-and-resume execution. For a wide range of applications, a significant amount of resources can be saved. We exhaustively evaluate and show the efficacy of BrewER on four real-world datasets.

These glycolipids also exist without a covalently bound protein, in particular on the cell surfaces of protozoan parasites where they are densely populated. GPIs and GPI-anchored proteins participate in multiple cellular processes such as signal transduction, cell adhesion, protein trafficking and pathogenesis of Malaria, Toxoplasmosis, Trypanosomiasis and prion diseases, among others. All GPIs share a common conserved glycan core modified in a cell-dependent manner with additional side glycans or phosphoethanolamine residues. Here, we use atomistic molecular dynamic simulations and perform a systematic study to evaluate the structural properties of GPIs with different side chains inserted in lipid bilayers. Our results show a flop-down orientation of GPIs with respect to the membrane surface and the presentation of the side chain residues to the solvent. This finding agrees well with experiments showing the role of the side residues as active epitopes for recognition of GPIs by macrophages and induction of GPI-glycan-specific immune responses. Protein-GPI interactions were investigated by attaching parasitic GPIs to Green Fluorescent Protein. GPIs are observed to recline on the membrane surface and pull down the attached protein close to the membrane facilitating mutual contacts between protein, GPI and the lipid bilayer. This model is efficient in evaluating the interaction of GPIs and GPI-anchored proteins with membranes and can be extended to study other parasitic GPIs and proteins and develop GPI-based immunoprophylaxis to treat infectious diseases.

As a nondestructive characterization method, synchrotron X-ray imaging, especially tomography, plays a particularly important role in structural characterization. A recent upgrade of key equipment of the BAMline widens its imaging capabilities: shorter scan acquisition times are now possible, in situ and op erando studies can now be routinely performed, and different energy spectra can easily be set up. In fact, the upgraded double-multilayer monochromator brings full flexibility by yielding different energy spectra to optimize flux and energy resolution as desired. The upgraded detector (based on an sCMOS camera) also allows exploiting the higher flux with reduced readout times. Furthermore, an installed slip ring allows the sample stage to continuously rotate. The latter feature enables tomographic observation of processes occurring in the time scale of a few seconds.

Possible beneficial mechanisms include reduced presence of preda-tors and competitors in small habitat areas or specific functions such as stepping stones for dispersal. Given the increasing amount of studies highlighting individual behavioral differences that may influence these functions, we hypothesize that the advantage of small versus large habitat patches not only depends on patch functionality but also on the presence of animal personalities (i.e., risk-tolerant vs. risk-averse). Using an individual-based, spatially-explicit community model, we analyzed the diversity of mammal communities in landscapes consisting of a few large habitat islands interspersed with different amounts and sizes of small habitat patches. Within these heterogeneous environments, individuals compete for resources and form home-ranges, with only risk-tolerant individuals using habitat edges. Results show that when risk-tolerant individuals exist, small patches increase species diversity. A strong peak occurs at approximately 20% habitat cover in small patches when those small habitats are only used for foraging but not for breeding and home-range core position. Additional usage as stepping stones for juvenile dispersal further increases species persistence. Over-all, our results reveal that a combination of a few large and several small habitat patches promotes biodiversity by enhancing land-scape heterogeneity. Here, heterogeneity is created by pronounced differences in habitat functionality, increasing edge density, and variability in habitat use by different behavioral types. The finding that a combination of single large AND several small (SLASS) patches is needed for effective biodiversity preservation has implications for advancing landscape conservation. Particularly in struc-turally poor agricultural areas, modern technology enables precise management with the opportunity to create small foraging habitats by excluding less profitable agricultural land from cultivation.

The transition to CE by public and private organizations can be seen as an entrepreneurial act encompassing their strategic policies, business models, structures, and processes. Little is known about the involvement of employees of organizations making this transition. Therefore, this study investigates the influence of organizations’ commitment to the five CE principles on their employees’ perceptions of the usefulness, ease of implementation, and acceptability of the principles. The method used is exploratory, a mixed-method approach combining PLS-SEM and fsQCA. This research contributes to the field by developing a unified theoretical perspective on the entrepreneurial context. It also highlights the impact of CE principles on organizations that are transitioning to more sustainable development.

Therefore, lower extremity kinematics were analysed in response to decelerative perturbations during running using statistical parametric mapping (SPM). 13 asymptomatic individuals (8 females & 5 males, 28 +/- 3 years, 171 +/- 9 cm, 68 +/- 10 kg) completed an 8-minute running protocol with 30 one-sided perturbations (15 each side) to generate decelerative disturbances. A 3D-motion capture system was employed to record kinematic data. Joint angles of the ankle, knee, and hip in addition to stride duration, stride length and step width were calculated for leading and trailing strides. Results were analysed descriptively, followed by SPM of paired t-tests (P < 0.025). Reactively (after perturbation), perturbations caused decreased hip adduction and stride duration of the leading leg. The trailing leg reacted with ankle inversion, knee and hip flexion, hip abduction, as well as an increase in stride duration and step width (P < 0.025). In preparation for perturbation, the trailing leg reduced ankle dorsiflexion, knee flexion, hip flexion, and adduction. In summary, applied perturbations produced substantial reactive (feedback) and predictive (feedforward) responses of the lower limbs, most apparent in the trailing leg.

BT - the advent of the neo-weberian state in Germany JF - Journal of policy studies N2 - In this contribution, the emergence of the neo-Weberian state (NWS) is analyzed with regard to German public administration. Drawing on the concept of a governance space, which consists of a hierarchy, markets, and networks, we distinguish between four empirical manifestations of the NWS, namely, the NWS as (1) come back of the public/ re-municipalization; (2) re-hierarchization; (3) de-agencification; (4) de-escalation in performance management. These movements can, on the one hand, be interpreted as a (partial) reversal of New Public Management (NPM) approaches and a “swinging back of the pendulum” (see Kuhlmann & Wollmann, 2019) toward public and classical Weberian principles (e.g., hierarchy, regulation, institutional re-aggregation). This reversal re-strengthened the hierarchy within the overall governance space to the detriment of, but without completely replacing, market mechanisms and networks. NPM’s failure to deliver what it promised and its inappropriateness as a response to more recent challenges connected to crises and wicked problems have engendered a partial return of the public and a move away from the economization logic of NPM. On the other hand, post-NPM reversals and managerial de-escalation gave rise to hybrid models that merge NPM and classic Weberian administration. While some well-functioning combinations of NPM and Weberianism exist, the hybridization of “old” and “neo” elements has also provoked ambivalent and negative assessments regarding the actual functioning of the NWS in Germany. Our analysis suggests that the NWS is only partially suitable as a model for reform and future administrative modernization, largely depending on the context surrounding reform and implementation practices.

However, there are no studies to date that examine the effect of such use on peer interactions and the occurrence of prosocial behavior in peers. For parents, it has been found that when using digital media only few parents respond responsively to their children's attempts at interaction and also very rarely, they communicate with them verbally and nonverbally. In the present study, we investigated how playing a game in a digital versus analog form influences in-teractions (especially prosocial behavior) of peers. We used an experimental situation, where 24 dyads of 4-10-year-old children were examined. Each of the dyads was randomly assigned to a condition where they played either a digital or analog game together. Various interaction parameters and prosocial behavior during and after the game were analyzed. Results show that children in the analog condition communicated verbally with each other more often, responded more often to interaction attempts of their partners and showed less often negative forms of inter-action and more often positive forms of interaction than children in the digital condition. However, the type of medium had no influence on prosocial behavior after the game situation. These results suggest that the format of a game (digital vs. analog) has a decisive influence on peer interactions concerning their communication during but not their prosocial behavior after the game situation.

Although, the Pregnancy Physical Activity Questionnaire (PPAQ) has been validated for use in assessing PA in pregnant women. However, understanding the knowledge and participation levels of PA in pregnant women in the underdeveloped regions of Ghana is of clinical relevance to foster education and promotion of PA. In Ghana, pregnant women believe the "myth" (mostly in rural areas and underdeveloped regions) that exercising in the first trimester might lead to miscarriage. Thus, the main objective of this study was to investigate the extent of knowledge and participation levels in PA among pregnant women in Ho, Ghana using a self-developed questionnaire which consisted of some questions adapted from the PPAQ. MethodsSeventy-seven (n = 77) pregnant women between the ages of 18-50 years were recruited from three hospitals across the Ho municipality of Ghana. A self-developed questionnaire which consisted of some questions taken from the PPAQ was administered to participants under the researchers' supervision. Spearman's correlation analysis was used to find the association between the level of participation in PA, knowledge of PA and gestational age among pregnant women. Results From the total participants (n = 77) recruited, 57 (74%) of the participants scored high in PA knowledge. Most of the participants 48 (62.3%) answered that PA promotes healthy pregnancy. Participants who reported barriers to PA during pregnancy were no exercise habits 51 (66.2%), having no time 17 (22.1%) and fear of miscarriage 9 (11.7%). There was a significant (p < 0.05) association between the level of participation and gestational age. No significant (p > 0.05) association between the level of participation and knowledge of PA was observed. Conclusion There is a high level of knowledge of PA among pregnant women in Ho, Ghana. However, most pregnant women rather engage in PA as their gestational age increases. Thus, to foster sustainable exercise participation during pregnancy, all healthcare providers saddled with the responsibility of providing maternal healthcare must strengthen the education and promotion of exercise and PA among pregnant women in Ho, Ghana.

Even though bereaved siblings can be identified as a high-risk group, evidence-based interventions for this bereavement group are still missing. Aim: To evaluate the treatment effects of an internet-based writing intervention for bereaved siblings aged 16-65 years. Design: A two-armed randomized controlled trial (DRKS00011514) compared the intervention to a waiting list control group. The 6-week intervention consisted of six structured writing assignments that were based on cognitive behavioral therapy, focusing on the specific situation of bereaved siblings. Setting/participants: Eighty-six bereaved siblings (loss >1 month ago, no severe psychiatric symptoms) were randomly allocated to the intervention group (n = 47) or the waiting list control group (n = 39). Primary outcomes were symptoms of prolonged grief disorder and depression; secondary outcomes were posttraumatic stress symptoms and survivor guilt. Results: Symptoms of depression and prolonged grief disorder improved significantly in the intention-to-treat analyses from pre-to post-measurement compared with the control group (g(Depression) = -0.62, g(Grief) = 0.33). In the intervention group, all primary and secondary outcomes decreased significantly from baseline to 12-month follow-up (gs = -0.38 to -1.04). A significant clinical change could be found for depression (34%) compared to the waitlist control group (10%). Conclusions: Bereaved siblings profited from this brief internet-based writing intervention in the short- and long-term. However, future research, such as dismantling studies, may help to further optimize the benefits of an intervention aimed at bereaved siblings.

We conducted multivariate covariance analyses using a largescale dataset of 446 traditionally certified (TC) teachers and 143 AC teachers at secondary schools in Germany. Findings show that AC teachers reported more frequently than TC teachers that they chose teaching due to social influences and because of more time for their family. Furthermore, AC teachers report significantly higher enthusiasm for teaching. No differences were found regarding emotional exhaustion or the intention to stay in the profession.

Contemporary adult education research shows that beliefs and memories from one's school years have an impact on the motivation to pursue further education in working life. However, almost no longitudinal research exists that investigates the long-term forces behind adults' motivation to educate themselves. Hence, the present study examined whether students' learning-related behaviour, cognitions and emotions that developed in their school years are related to the subjective value they place on further education, their expectations of success in solving further learning tasks, and thus the likelihood of participating in further education. Corresponding structural equation analyses on data from the German panel study LifE (n = 1,110) revealed that the learning behaviour, ability self-concept and test anxiety at the age of 12, along with their individual change between the ages of 12 and 16, are associated in different ways with the attainment value and subjective costs placed on further education and expectations of success at the age of 35. In contrast, no influence of youth characteristics on the likelihood of participating in further education could be found. The findings indicate that especially the development of learning-related cognitions and emotions in secondary school is sustainably related to the individual's success expectancy and achievement value of further education. Long-term dependencies should be further investigated with regard to academic domains and socio-economic pathways.

With the availability of Intel Optane DC Persistent Memory, initial benchmarks evaluate the performance of real PMem hardware. However, these results apply to only a single server and it is not yet clear how workloads compare across different PMem servers. In this paper, we propose PerMA-Bench, a con.gurable benchmark framework that allows users to evaluate the bandwidth, latency, and operations per second for customizable database-related PMem access. Based on PerMA-Bench, we perform an extensive evaluation of PMem performance across four di.erent server configurations, containing both first- and second-generation Optane, with additional parameters such as DIMM power budget and number of DIMMs per server. We validate our results with existing systems and show the impact of low-level design choices. We conduct a price-performance comparison that shows while there are large differences across Optane DIMMs, PMem is generally competitive with DRAM. We discuss our findings and identify eight general and implementation-specific aspects that influence PMem performance and should be considered in future work to improve PMem-aware designs.

Based on that importance, their concentrations are tightly regulated in mammalian organisms. The maintenance of those levels is termed trace element homeostasis and mediated by a combination of processes regulating absorption, cellular and systemic transport mechanisms, storage and effector proteins as well as excretion. Due to their chemical properties, some functions of trace elements overlap, as seen in antioxidative defence, for example, comprising an expansive spectrum of antioxidative proteins and molecules. Simultaneously, the same is true for regulatory mechanisms, causing trace elements to influence each other’s homeostases. To mimic physiological conditions, trace elements should therefore not be evaluated separately but considered in parallel. While many of these homeostatic mechanisms are well-studied, for some elements new pathways are still discovered. Additionally, the connections between dietary trace element intake, trace element status and health are not fully unraveled, yet. With current demographic developments, also the influence of ageing as well as of certain pathological conditions is of increasing interest. Here, the TraceAge research unit was initiated, aiming to elucidate the homeostases of and interactions between essential trace elements in healthy and diseased elderly. While human cohort studies can offer insights into trace element profiles, also in vivo model organisms are used to identify underlying molecular mechanisms. This is achieved by a set of feeding studies including mice of various age groups receiving diets of reduced trace element content. To account for cognitive deterioration observed with ageing, neurodegenerative diseases, as well as genetic mutations triggering imbalances in cerebral trace element concentrations, one TraceAge work package focuses on trace elements in the murine brain, specifically the cerebellum. In that context, concentrations of the five essential trace elements of interest, copper, iron, manganese, selenium and zinc, were quantified via inductively coupled plasma-tandem mass spectrometry, revealing differences in priority of trace element homeostases between brain and liver. Upon moderate reduction of dietary trace element supply, cerebellar concentrations of copper and manganese deviated from those in adequately supplied animals. By further reduction of dietary trace element contents, also concentrations of cerebellar iron and selenium were affected, but not as strong as observed in liver tissue. In contrast, zinc concentrations remained stable. Investigation of aged mice revealed cerebellar accumulation of copper and iron, possibly contributing to oxidative stress on account of their redox properties. Oxidative stress affects a multitude of cellular components and processes, among them, next to proteins and lipids, also the DNA. Direct insults impairing its integrity are of relevance here, but also indirect effects, mediated by the machinery ensuring genomic stability and its functionality. The system includes the DNA damage response, comprising detection of endogenous and exogenous DNA lesions, decision on subsequent cell fate and enabling DNA repair, which presents another pillar of genomic stability maintenance. Also in proteins of this machinery, trace elements act as cofactors, shaping the hypothesis of impaired genomic stability maintenance under conditions of disturbed trace element homeostasis. To investigate this hypothesis, a variety of approaches was used, applying OECD guidelines Organisation for Economic Co-operation and Development, adapting existing protocols for use in cerebellum tissue and establishing new methods. In order to assess the impact of age and dietary trace element depletion on selected endpoints estimating genomic instability, DNA damage and DNA repair were investigated. DNA damage analysis, in particular of DNA strand breaks and oxidatively modified DNA bases, revealed stable physiological levels which were neither affected by age nor trace element supply. To examine whether this is a result of increased repair rates, two steps characteristic for base excision repair, namely DNA incision and ligation activity, were studied. DNA glycosylases and DNA ligases were not reduced in their activity by age or trace element depletion, either. Also on the level of gene expression, major proteins involved in genomic stability maintenance were analysed, mirroring results obtained from protein studies. To conclude, the present work describes homeostatic regulation of trace elements in the brain, which, in absence of genetic mutations, is able to retain physiological levels even under conditions of reduced trace element supply to a certain extent. This is reflected by functionality of genomic stability maintenance mechanisms, illuminating the prioritization of the brain as vital organ. N2 - Als essentielle Mikronährstoffe spielen die Spurenelemente Kupfer, Eisen, Mangan, Selen und Zink eine wichtige Rolle für eine Vielzahl zellulärer Prozesse. Aufgrund dessen unterliegen ihre Konzentrationen in der Peripherie einer strengen Regulation. Die Aufrechterhaltung dieser Konzentrationen wird als Spurenelementhomöostase bezeichnet und beruht auf der Kombination verschiedener Mechanismen hinsichtlich ihrer Absorption, des zellulären und systemischen Transports, der Regulation von Speicher- und Effektorproteinen sowie ihrer jeweiligen Exkretion. Aufgrund ihrer chemischen Eigenschaften überschneiden sich einige Funktionen der Spurenelemente. Beispielsweise ist hier die antioxidative Abwehr zu nennen, an welcher eine Vielzahl verschiedener antioxidativer Moleküle und Proteine beteiligt sind. Gleiches gilt für regulative Mechanismen, wodurch Spurenelemente unter Umständen ihre jeweiligen Homöostasen gegenseitig beeinflussen können. Um physiologische Bedingungen abzubilden, sollten Spurenelemente somit nicht isoliert betrachtet, sondern gemeinsam untersucht werden. Obwohl viele homöostatische Mechanismen bereits gut erforscht sind, werden für einige Elemente immer noch neue Stoffwechselwege identifiziert. Darüber hinaus sind auch die Zusammenhänge zwischen der Spurenelementaufnahme aus der Nahrung sowie dem Spurenelement- und Gesundheitsstatus noch nicht vollständig aufgeklärt. Im Zuge der aktuellen demografischen Entwicklung steigt zudem das Interesse daran, den Einfluss des Alterungsprozesses sowie bestimmter Erkrankungen zu untersuchen. In diesem Kontext wurde die Forschungsgruppe TraceAge gegründet, welche dazu beitragen soll, zum einen die homöostatische Regulation und zum anderen die Interaktionen essentieller Spurenelemente in gesunden und erkrankten älteren Menschen zu untersuchen. Hierbei werden einerseits humane Kohortenstudien beprobt, so dass Spurenelementprofile erstellt werden können. Darüber hinaus werden auch in vivo Modellorganismen verwendet, um zugrundeliegende molekulare Mechanismen zu erfassen. In murinen Fütterungsstudien erhielten Tiere unterschiedlicher Altersgruppen deshalb eine spurenelementreduzierte Diät. Um kognitive Beeinträchtigungen zu beachten, wie sie neben dem Altern auch bei neurodegenerativen Erkrankungen sowie bestimmten genetischen Mutationen, meist im Zusammenhang mit Spurenelementdishomöostasen, auftreten, konzentriert sich ein Projektbereich auf die Wechselwirkung von Spurenelementen im murinen Gehirn, wobei hier der Fokus auf das Cerebellum gelegt wurde. In diesem Zusammenhang wurden die Konzentrationen fünf essentieller Spurenelemente, Kupfer, Eisen, Mangan, Selen und Zink, mittels Massenspektrometrie mit induktiv gekoppeltem Plasma in den Organen der Tiere quantifiziert, wodurch sich Unterschiede in der Priorität der Aufrechterhaltung von Spurenelementhomöostasen zwischen Gehirn und Leber aufzeigten. Eine moderate Verringerung der Spurenelementgehalte in der gefütterten Diät wirkte sich dabei besonders auf die Konzentrationen von cerebellärem Kupfer und Mangan aus. Bei weiterer Spurenelementreduktion sanken auch die Konzentrationen von cerebellärem Eisen und Selen. Im Vergleich zur Leber waren diese Abnahmen jedoch weniger ausgeprägt. Im Gegensatz dazu blieben die Zinkkonzentrationen in Leber und Gehirn unverändert. Untersuchungen in älteren Mäusen zeigten eine Akkumulation von Kupfer und Eisen im Cerebellum. Möglicherweise trägt dies durch deren Redoxeigenschaften zur Entstehung von oxidativem Stress bei. Oxidativer Stress wirkt sich auf eine Vielzahl zellulärer Bestandteile, wie Proteine und Lipide, aber auch auf die DNA, sowie auf den Ablauf von Zellvorgängen aus. Dabei sind einerseits direkte Einflüsse auf die strukturelle Integrität der DNA von Relevanz, andererseits auch indirekte Effekte, welche durch Mechanismen zur Aufrechterhaltung der genomischen Stabilität vermittelt werden. Dieses System beinhaltet die DNA-Schadensantwort, welche die Identifikation von DNA-Schäden und die Entscheidung über das weitere Schicksal der Zelle beinhaltet. Darüber hinaus ist diese für die Initiation der DNA-Reparatur verantwortlich, welche einen weiteren zentralen Mechanismus zur Instandhaltung genomischer Stabilität darstellt. Auch die Proteine der DNA-Reparaturwege nutzen Spurenelemente als Kofaktoren, worin die Hypothese zur Beeinträchtigung der Aufrechterhaltung der genomischen Stabilität unter Bedingungen einer inadäquaten Spurenelementversorgung begründet wird. Um diese Hypothese zu prüfen, wurden in der vorliegenden Arbeit diverse Methoden unter Anwendung von OECD-Richtlinien, der Anpassung existierender Versuchsvorschriften an die spezifischen Anforderungen von Cerebellumgewebe, sowie die Entwicklung neuer Methoden angewandt. Zur Einschätzung des Einflusses von Alter und Spurenelementversorgung aus der Diät auf verschiedene Endpunkte der genomischen Instabilität wurden insbesondere die DNA-Schädigungen und die DNA-Reparatur als molekulare Zielstrukturen analysiert. DNA-Schäden, primär DNA-Strangbrüche und oxidativ modifizierte DNA-Basen, wiesen dabei stabile, physiologische Level auf, die nicht durch Alter oder Spurenelementzufuhr verändert wurden. Um festzustellen, ob dies ein Resultat erhöhter Reparaturvorgänge ist, wurden zwei charakteristische Schritte der Basenexzisionsreparatur, DNA-Inzision und DNA-Ligation, näher untersucht. Es zeigte sich jedoch kein Einfluss auf die DNA-Reparatur einleitenden DNA-Glykosylasen sowie auf die DNA-Reparatur abschließenden DNA-Ligasen. Auch auf Genexpressionsebene wurden wichtige Gene der Proteine der genomischen Stabilität analysiert, welche die Ergebnisse proteinbezogener Studien widerspiegelten. Abschließend lässt sich somit feststellen, dass die Spurenelementhomöostase des Gehirns, selbst unter Bedingungen der defizienten Spurenelementzufuhr, streng reguliert ist. Dadurch können physiologische Spurenelementkonzentrationen bis zu einem gewissen Grad konstant gehalten werden. Dies spiegelt sich auch in der Funktionalität von Mechanismen zur Erhaltung genomischer Stabilität wider, welche die Priorität des Gehirns im Organismus unterstreicht.

Ein Manifest und weitere Erklärungen JF - Deutsche Zeitschrift für Philosophie : Zweimonatsschrift der internationalen philosophischen Forschung N2 - The aim of the paper is to defend the project of transforming philosophy carried out in my book 'Vernunft und Temperament. Eine Philosophie der Philosophie'. In section 1, I distinguish between five philosophical genres in which transformation plays a role: 1. academic texts in which transformation is simply a topic; 2. texts meant to adequately articulate through their form the transformative experiences of their authors; 3. texts aiming to enable the reader to transform herself; 4. texts on other texts; 5. manifestos defending the project of transforming philosophy. Section 2 is such a manifesto. Its main thesis is: "What makes somebody - anybody - a good philosopher is that she is a real human being. " Many of the remaining 16 theses of the manifesto are elaborations on this main thesis. One example is the thesis that the philosophical activity is essentially a becoming - the development of an individual human being.

This mixed-methods study investigated changes in reflection-related self-efficacy and dif-ferences in written reflection processes using a quasi-experimental design with two types of reflection stimuli. One group of 46 student teachers used a VR-based video to reflect on in-struction while another group of 23 student teachers used a real classroom video. We found an increase in reflection-related self-efficacy over time among participants in the VR group only. We also found that VR videos triggered similar reflection processes to real classroom videos. This study shows, for the first time, that video-based reflection on VR classroom videos produced comparable results to reflection on real classroom videos. This indicates that VR can be used successfully in teacher education and that it offers a useful learning tool for teacher education programs.

Moving away from portrayals of eastern African childhood as characterised by want, the author argues for a differentiated and pluralist nature of the eastern African childhood. Taking a chronological approach, the author provides a multidisciplinary critical reading of Africanist research on childhood in eastern Africa, drawing from anthropological and cultural studies, while examining writings from the pre-imperial and colonial periods. Moving into the contemporary period, the book reveals the continuity, tensions and ruptures of these portrayals in humanitarian, legal, and journalistic discourses, before exploring postcolonial writings on childhood in works by Eastern African novelists. Based on such a multidisciplinary perspective, this book will be of interest to scholars of African literature, eastern African history, critical childhood studies, museums and Africanist epistemologies.

A1 - Lauterbach, Wolfgang T1 - Fearful future: the worldwide shadow education epidemic and the reproduction of inequality outside public schooling T2 - Theorizing shadow education and academic success in East Asia: Understanding the meaning, value, and use of shadow education by East Asian students N2 - Shadow education has become part of mass schooling in many societies. Against the background of the continuing expansion of formal education and the persistence of educational and social inequalities, the growing influence of shadow education begs major implications for the postulated goal of equality in educational opportunities. This chapter addresses this issue both theoretically and empirically, focusing on the following question: What is the relationship between the continuous growth of SE across the world and the persistence of social inequality in educational attainment? First, existing findings on the topic are reviewed before I draw on and expand neo-institutionalist and social reproduction theories to incorporate SE, thereby identifying the universal causes for the inevitable expansion of SE and its relation to social inequality across the world. Finally, policy implications and future research directions are discussed. The results of this analysis indicate that even though there exist tremendous differences in the effects of family background on SE use in different regions and systems of education across the world, SE always feeds into the broader institutionalization of education and its role for social stratification. SE might occupy a key role in maintaining vertical and horizontal inequalities in educational attainment in schooled societies, which continue to struggle with inequity of educational opportunities and outcomes in spite of massive educational expansion at the higher education levels and more equity in educational opportunities.

Furthermore, degrees of employee involvement that the intervention formats address are identified and related to the goals of employee participation. On this basis, determinants of employee involvement and participation in the context of digital transformation are unveiled. Design/methodology/approach Based on a systematic literature review the authors structure and relate employee participation goals and formats. Through a workshop with expert practitioners, the authors transfer and enhance these theoretical findings in the context of digital transformation. Experts rated the three most important goals and identified accompanying success factors, barriers and effects. Findings The results show that it is not necessarily the degree of involvement but a context-specific selection of measures, the quality of their implementation as well as the actual uptake of suggestions and activities developed by employees that contribute to employees accepting and participating in goal-directed transformations. Moreover, employees must have sufficient information and time for their participation in transformation processes. Originality/value This paper is based on a transformative approach, combining literature analysis to identify formats and goals of employee participation with experiential knowledge of digital transformation practitioners. In addition to relating intervention formats to goals pursued in organizational change processes, empirical and experiential perspectives are used to identify three very relevant goals and respective determinants in digital transformation processes.

With her new party, former Die Linke politician Sahra Wagenknecht combines a left-authoritarian profile (economically left-leaning, but culturally conservative) with anti-US, pro-Russia and anti-elitist stances. This article provides the first large-n academic study of the voter potential of this new party by using a quasi-representative sample (n = 6,000) drawn from a Voting Advice Application-like dataset that comes from a website designed to explore the Bündnis Sahra Wagenknecht’s positions. The results show that congruence with foreign policy positions and anti-elitism are strong predictors of the propensity to vote for the Bündnis Sahra Wagenknecht. In contrast, social/welfare and immigration policies are less predictive for assessing the party’s potential. Among the different socio-demographic groups, the Bündnis Sahra Wagenknecht has a strong potential among baby boomers, the less educated and East Germans. Regarding party voters, the Bündnis Sahra Wagenknecht is favoured by supporters of some minor parties like dieBasis, Freie Wähler and Die PARTEI, but also non-voters. Among the established parties, the party’s potential is high among Die Linke voters and, to a lesser extent, voters of the Social democrats (SPD) and Alternative for Germany (AfD). A potential below the average is reported for the supporters of the Liberals (FDP) and Christian Democrats (CDU/CSU) and most clearly for Green and Volt voters.

Sudden increases in irregular immigration create a sense of loss of control, which is instrumentalised by populist forces. This has generated great interest in quantitative migration predictions. High expectations are placed in the AI-based tools currently under devel­op­ment for forecasting irregular migration. The potential applications of these tools are manifold. They range from managing and strengthening the EU's reception capacity and border protections to configuring humanitarian aid provision and longer-term planning of development programmes. There is a significant gap between the expectations placed in the new instruments and their practical utility. Technical limits exist, medium-term forecasts are methodologically implausible, and channels for feeding the results into political decision-making processes are lacking. The great demand for predictions is driven by the political functions of migration prediction, which include its uses in political communication, funding acquisition and legitimisation of political decisions. Investment in the quality of the underlying data will be more productive than developing a succession of new prediction tools. Funding for applications in emergency relief and development cooperation should be prioritised. Crisis early warning and risk analysis should also be strengthened and their networking improved.

Plötzliche Anstiege ungeregelter Zuwanderung nähren ein Gefühl von Kontrollverlust, das wiederum von populistischen Kräften instrumentalisiert wird. Daher hat die Politik großes Interesse an quantitativen Migrationsprognosen. Besondere Erwartungen wecken KI-gestützte Instrumente zur Vorhersage ungeregelter Wanderungsbewegungen, wie sie zurzeit entwickelt werden. Die Anwendungsfelder dieser Instrumente sind vielfältig. Sie reichen von einer Stärkung der Aufnahmekapazitäten in der EU über die präventive Verschärfung von Grenzschutzmaßnahmen und eine bedarfsgerechte Bereitstellung von Ressourcen in humanitären Krisen bis zur längerfristigen entwicklungspolitischen Programmplanung. Allerdings besteht eine deutliche Kluft zwischen den Erwartungen an die neuen Instrumente und ihrem praktischen Mehrwert. Zum einen sind die technischen Möglichkeiten begrenzt, und mittelfristige Vorhersagen zu ungeregelten Wanderungen sind methodisch kaum möglich. Zum anderen mangelt es an Verfahren, um die Ergebnisse in politische Entscheidungsprozesse einfließen zu lassen. Die hohe Nachfrage nach Prognosen erklärt sich aus den politischen Funktionen quantitativer Migrationsvorhersage - beispielsweise ihrem Potential für die politische Kommunikation, die Mitteleinwerbung und die Legitimierung politischer Entscheidungen. Investitionen in die Qualität der den Prognosen zugrunde liegenden Daten sind sinnvoller als die Entwicklung immer neuer Instrumente. Bei der Mittelvergabe für Prognosen sollten Anwendungen in der Nothilfe und der Entwicklungszusammenarbeit priorisiert werden. Zudem sollten die Krisenfrüherkennung und die Risikoanalyse gestärkt werden, und die beteiligten Akteure sollten sich besser vernetzen.

Social media generates a wealth of data which migration scholars have recently started to explore in pursuit of a variety of methodological and thematic research questions. Scholars use social media data to estimate migration stocks, forecast migration flows, or recruit migrants for targeted online surveys. Social media has also been used to understand how migrants get information about their planned journeys and destination countries, how they organize and mobilize online, how migration issues are politicized online, and how migrants integrate culturally into destination countries by sharing common interests. While social media data drives innovative research, it also poses severe challenges regarding data privacy, data protection, and methodological questions relating to external validity. In this chapter, I briefly introduce various strands of migration research using social media data and discuss the advantages, disadvantages, and opportunities.

JF - European journal of political research N2 - In 2015, German Chancellor Angela Merkel decided to allow over a million asylum seekers to cross the border into Germany. One key concern was that her decision would signal an open-door policy to aspiring migrants worldwide – thus further increasing migration to Germany and making the country permanently more attractive to irregular and humanitarian migrants. This ‘pull-effect’ hypothesis has been a mainstay of policy discussions ever since. With the continued global rise in forced displacement, not appearing welcoming to migrants has become a guiding principle for the asylum policy of many large receiving countries. In this article, we exploit the unique case study that Merkel's 2015 decision provides for answering the fundamental question of whether welcoming migration policies have sustained effects on migration towards destination countries. We analyze an extensive range of data on migration inflows, migration aspirations and online search interest between 2000 and 2020. The results reject the ‘pull effect’ hypothesis while reaffirming states’ capacity to adapt to changing contexts and regulate migration.

The pandemic offers an excellent empirical lens for scrutinizing the phenomenon of polycrises governance because it occurred while European countries were struggling with the impacts of several prior, ongoing, or newly arrived crises. Our major focus is on institutional design variants of crisis governance (dependent variable) and the influence of different administrative cultures on it (independent variable). Furthermore, we analyze the entanglement and interaction of institutional responses to other (previous or parallel) crises (polycrisis dynamics). Our findings reveal a huge variance of institutional designs, largely evoked by country-specific administrative cultures and profiles. The degree of de-/centralization and the intensity of coordination or decoupling across levels of government differs significantly by country. Simultaneously, all countries were affected by interrelated and entangled crises, resulting in various patterns of polycrisis dynamics. While policy failures and “fatal remedies” from previous crises have partially impaired the resilience and crisis preparedness of local governments, we have also found some learning effects from previous crises.

Due to high research productivity, it is challenging to keep track of the abundance of publications. Against this background, we employ a bibliographic coupling analysis to gain a comprehensive understanding of current research topics. The following themes were defined: Key factors for success, word of mouth and social media, organizational and pedagogical dimensions, advertising—product placement and online marketing, tourism, the influence of data, the influence of culture, revenue maximization and purchase decisions, and the perception and identification of audiences. Based on the cluster analysis, we suggest the following future research opportunities: Exploring technological innovations, especially the influence of social media and streaming platforms in the film industry; the in-depth analysis of the use of artificial intelligence in film production, both in terms of its creative potential and ethical and legal challenges; the exploration of the representation of wokeness and minorities in films and their cultural and economic significance; and, finally, a detailed examination of the long-term effects of the COVID-19 pandemic and other crises on the film industry, especially in terms of changed consumption habits and structural adjustments.

The testimonium primarily focuses on the Convetion's authentic languages, regulation of deposition, and certified true copies being delivered to all members of the UN and non-member States. On the other hand, Article XI contains the standard procedures for regulating the deposition of a copy of the 1967 Protocol in the Secretariat of the United Nations and foreseeing the transmission of certified copies thereof by the Secretary general. The chapter mentions how both elements are not commonly explicitly indicated in modern treaties.

The analysis involves computational reproducibility checks and robustness assessments. It reveals several patterns. First, we uncover a high rate of fully computationally reproducible results (over 85%). Second, excluding minor issues like missing packages or broken pathways, we uncover coding errors for about 25% of studies, with some studies containing multiple errors. Third, we test the robustness of the results to 5,511 re-analyses. We find a robustness reproducibility of about 70%. Robustness reproducibility rates are relatively higher for re-analyses that introduce new data and lower for re-analyses that change the sample or the definition of the dependent variable. Fourth, 52% of re-analysis effect size estimates are smaller than the original published estimates and the average statistical significance of a re-analysis is 77% of the original. Lastly, we rely on six teams of researchers working independently to answer eight additional research questions on the determinants of robustness reproducibility. Most teams find a negative relationship between replicators' experience and reproducibility, while finding no relationship between reproducibility and the provision of intermediate or even raw data combined with the necessary cleaning codes.

It explains the depository of a treaty playing an essential procedural role in ensuring the smooth operation of a multilateral treaty. Article 46 enumerates the Secretary-General's function as a depositary performed by the Treaty Section of the Office of Legal Affairs in the United Nations Secretariat. Similarly, Article X confirms and details the Secretary-General's designation and role as depositary of the 1967 Protocol. The chapter mentions that the enumeration of Article X's depositary notification is exemplary instead of conclusive. It examines the depositoary notifications of declarations, signatures, and researvations under Article 46 and Article X.

It starts with identifying the standard denunciation clause in Article 44 and Article IX. Multilateral treaties of unlimited duration allow States parties an unconditional right to withdraw. A denunciation releases the denouncing party from any obligation further to perform the treaty in relation to the other parties of the 1967 Protocol. The chapter clarifies that denunciation or withdrawal expresses the same legal concept since it is a procedure initiated unilaterally by a State that wants to terminate its legal engagements under a treaty.

It explains that a multilateral treaty can be enforced when met with necessary conditions, such as the Article 24 of the Vienna Convention on the Law of Treaties (VCLT). The provision also regulates the 1951 Convention's entry into force of States' ratification or accession. The chapter notes that the 1967 Protocol entered into force after Sweden deposited its instrument of accession. It elaborates on the specific details needed for the ratification or accession prior to the entry into force.

Comparing adolescents who responded to our survey shortly before the start of the war with those who responded shortly after the conflict began and applying difference-in-differences (DiD) models over time, we find a significant decline in the outcome after the war started. These findings provide new evidence on how armed conflicts influence social trust and well-being among young people in a country not directly involved in the war.

In 2000, the Secretary-General identified the 1951 Convention as belonging to a core group of 25 multilateral treaties representative of the key objectives of the UN and the spirit of its Charter. Additionally, the rules found in the Vienna Convention on the Law of Treaties (VCLT) apply to the 1951 Convention as a matter of customary international law. On the other hand, the 1967 Protocol does not amend the 1951 Convention but binds its parties to observe the substantive provisions. The chapter cites that the 1967 Protocol constitutes an independent and complete international instrument that is open not only to the States parties to the 1951 Convention.

It explains the function of the provision, which primarily focuses on requesting Contracting States to facilitate the assimilation and naturalization of refugees. Moreover, the provision forms the legal bases for local integration and naturalization as some of the traditional durable solutions to refugeehood. The soft obligation imposed by Article 34 primarily focuses on the long-term solution by naturalization. The chapter then elaborates on the balance between local integration, naturalization, and voluntary return after it was disrupted due to the fall of the Iron Curtain in 1989.

Moreover, Article 22 encompasses learning at all different levels of education in schools, universities, and other educational institutions. However, the provision does not address any issues related to the upbringing of children by their parents. The chapter mentions the relevancy of Article 22 when it comes to durable solutions for refugees in an effort to enable them to integrate into the host country's society.

It refers to a special group of people who qualify for refugee status but enjoy the rights of national citizens despite their lack of formal citizenship. The article's object and purpose revolve around excluding persons from refugee protection who do not need any international protection since they have the status of national citizens. Additionally, access to refugee status is excluded ipso facto because the individual may resort to effective protection similar to that of citizenship upon being admitted to the country of sojourn. The chapter explains how Article 1 E is an integral part of the balanced system of international refugee protection prescribed by the Convention.

The article primarily determines the scope of application of the Convention's ratione personae while outlining the basis of the protection of refugees. Additionally, Article 1 addresses the concerns surrounding the inclusion, cessation, and exclusion of refugees. The chapter then tackles the historical development of the article by considering the instruments used prior to the 1951 Convention. It also cites that the Constitution of the International Refugee Organization appears to contain an ambiguity as to how the refugee notion was perceived, so refugees only became the IRO Constitution's concern when they have valid objections to returning to their home country.

Contrastive corpus studies demonstrate that oral genres include longer average anaphoric distance than written genres, if the distance is measured in terms of clauses (Fox, 1987; Aktas & Stede, 2020). We designed an experiment in order to examine the contrasts in oral and written mediums, using the same genre. We aim to gain more insight about the impact of the medium, in a situation where both mediums convey a similar level of spontaneity, informality and interactivity. We designed a story continuation study, where the participants are recruited via crowdsourcing. To our knowledge, this is the first study of its kind, where anaphoric distance is manipulated systematically in a language production experiment in order to examine medium distinctions. We observed that participants use more pronouns in oral medium than in written medium if the anaphoric distance is long. This result is in line with the implications of the earlier corpus-based research. In addition, our results indicate that anaphoric distance has a larger effect in referential choice for the written medium.

Consolidating previous international instruments relating to refugees, the 1951 Convention with its 1967 Protocol marks a cornerstone in the development of international refugee law. At present, there are 144 States Parties to one or both of these instruments, expressing a worldwide consensus on the definition of the term refugee and the fundamental rights to be granted to refugees. These facts demonstrate and underline the extraordinary significance of these instruments as the indispensable legal basis of international refugee law. This Commentary provides for a systematic and comprehensive analysis of the 1951 Convention and the 1967 Protocol on an article-by-article basis, exposing the interrelationship between the different articles and discussing the latest developments in international refugee law. In addition, several thematic contributions analyse questions of international refugee law which are of general significance, such as regional developments and the relationship between refugee law and the law of the sea.

T1 - Directing the war from triumph to disaster BT - the German and Italian cases JF - The Routledge History of the Second World War N2 - After the Second World War, Adolf Hitler and Benito Mussolini were singled out as evil geniuses who misled the masses and plunged them into an “unwanted war.” In relation to their armed forces, this narrative argued that the generals under their command had been demoted to powerless tools in the hands of the dictators, having to follow orders and with no sway over decision-making. It was further asserted that Germany and Italy had not been able to secure a victory due to the dictators’ meddling. Yet, as this chapter shows, there are important differences between the German and Italian cases. The chapter compares both the command structures in which the dictators operated as well as their grand strategies and how they cooperated during the war. Their personal relationship will be also analyzed, as it is impossible to look at the Axis without understanding the complex personal relationship at the very top. The strategies of both Hitler and Mussolini will be looked at and how each leader behaved in terms of working with their closest ally, together with some examples of cooperation on the lower military rungs.

More precisely, we study a class of infinite-dimensional diffusions under Gibbsian interactions, in the context of marked point configurations: the starting points belong to R-d, and the marks are the paths of Langevin diffusions. We use the entropy method to prove existence of an infinite-volume Gibbs point process and use cluster expansion tools to provide an explicit activity domain in which uniqueness holds.

This article argues that the origins and political histories that the concepts of demos and democracy stand on provide a firm ground to resist the attempts at their current nativist/nationalist closure. Contesting the attempts to reduce the concepts of democracy and demos to strictly limited or ethnically defined populations, the article develops a political argument that relates democracy and migration, which have been represented as opposite poles within the current political map defined by the populist surge.

The acquisition of increasingly precise mental number line representations is assumed to support arithmetic learning in children. It is further suggested that sensorimotor experiences shape the development of number concepts and arithmetic learning, and that mental arithmetic can be characterized as “motion along a path” and might constitute shifts in attention along the mental number line. The present study investigated whether movements in physical space influence mental arithmetic in primary school children, and whether the expected effect depends on concurrency of body movements and mental arithmetic. After turning their body towards the left or right, 48 children aged 8 to 10 years solved simple subtraction and addition problems. Meanwhile, they either walked or stood still and looked towards the respective direction. We report a congruency effect between body orientation and operation type, i.e., higher performance for the combinations leftward orientation and subtraction and rightward orientation and addition. We found no significant difference between walking and looking conditions. The present results suggest that mental arithmetic in children is influenced by preceding sensorimotor cues and not necessarily by concurrent body movements.

The increasing importance of distinguishing human movements, particularly in healthcare, coincides with the advent of increasingly compact sensors. A complex sequence of individual steps currently characterizes the activity recognition pipeline. It involves separate data collection, preparation, and processing steps, resulting in a heterogeneous and fragmented process. To address these challenges, we present a comprehensive framework, HARE, which seamlessly integrates all necessary steps. HARE offers synchronized data collection and labeling, integrated pose estimation for data anonymization, a multimodal classification approach, and a novel method for determining optimal sensor placement to enhance classification results. Additionally, our framework incorporates real-time activity recognition with on-device model adaptation capabilities. To validate the effectiveness of our framework, we conducted extensive evaluations using diverse datasets, including our own collected dataset focusing on nursing activities. Our results show that HARE’s multimodal and on-device trained model outperforms conventional single-modal and offline variants. Furthermore, our vision-based approach for optimal sensor placement yields comparable results to the trained model. Our work advances the field of sensor-based human activity recognition by introducing a comprehensive framework that streamlines data collection and classification while offering a novel method for determining optimal sensor placement.

Therefore, membrane-binding proteins, together with structural components such as actin filaments, modulate the cell membrane in their flexibility, stiffness, and curvature. Investigating membrane components and curvature in cells remains challenging due to the diffraction limit in light microscopy. Preparation of 5–15-nm-thin plasma membrane sheets and subsequent inspection by metal replica transmission electron microscopy (TEM) reveal detailed information about the cellular membrane topology, including the structure and curvature. However, electron microscopy cannot identify proteins associated with specific plasma membrane domains. Here, we describe a novel adaptation of correlative super-resolution light microscopy and platinum replica TEM (CLEM-PREM), allowing the analysis of plasma membrane sheets with respect to their structural details, curvature, and associated protein composition. We suggest a number of shortcuts and troubleshooting solutions to contemporary PREM protocols. Thus, implementation of super-resolution stimulated emission depletion (STED) microscopy offers significant reduction in sample preparation time and reduced technical challenges for imaging and analysis. Additionally, highly technical challenges associated with replica preparation and transfer on a TEM grid can be overcome by scanning electron microscopy (SEM) imaging. The combination of STED microscopy and platinum replica SEM or TEM provides the highest spatial resolution of plasma membrane proteins and their underlying membrane and is, therefore, a suitable method to study cellular events like endocytosis, membrane trafficking, or membrane tension adaptations.

Of particular concern are overuse injuries (non-traumatic injuries). These injuries tend to present in the upper body and might be preventable with adequate knowledge of risk factors which could inform about injury prevention strategies. Research in this area has recently emerged but has yet to be synthesized comprehensively. Therefore, the aim of this study was to conduct a systematic review of the potential risk factors and injury prevention strategies for overuse injuries in adult climbers. Methods This systematic review was conducted in accordance with the PRISMA guidelines. Databases were searched systematically, and articles were deemed eligible based upon specific criteria. Research included was original and peer-reviewed, involving climbers, and published in English, German or Czech. Outcomes included overuse injury, and at least one or more variable indicating potential risk factors or injury prevention strategies. The methodological quality of the included studies was assessed with the Downs and Black Quality Index. Data were extracted from included studies and reported descriptively for population, climbing sport type, study design, injury definition and incidence/prevalence, risk factors, and injury prevention strategies. Results Out of 1,183 records, a total of 34 studies were included in the final analysis. Higher climbing intensity, bouldering, reduced grip/finger strength, use of a “crimp” grip, and previous injury were associated with an increased risk of overuse injury. Additionally, a strength training intervention prevented shoulder and elbow injuries. BMI/body weight, warm up/cool downs, stretching, taping and hydration were not associated with risk of overuse injury. The evidence for the risk factors of training volume, age/years of climbing experience, and sex was conflicting. Discussion This review presents several risk factors which appear to increase the risk of overuse injury in climbers. Strength and conditioning, load management, and climbing technique could be targeted in injury prevention programs, to enhance the health and wellbeing of climbing athletes. Further research is required to investigate the conflicting findings reported across included studies, and to investigate the effectiveness of injury prevention programs.

The classical definition of deficiency relates to the capacity of a network to permit variations of the complex formation rate vector at steady state, irrespective of the network kinetics. However, the deficiency is by definition completely insensitive to the fine details of the directionality of reactions as well as bounds on reaction fluxes. While the classical definition of deficiency can be readily applied in the analysis of unconstrained, weakly reversible networks, it only provides an upper bound in the cases where relevant constraints on reaction fluxes are imposed. Here we propose the concept of effective deficiency, which provides a more accurate assessment of the network’s capacity to permit steady state variations at the complex level for constrained networks of any reversibility patterns. The effective deficiency relies on the concept of nonstoichiometric balanced complexes, which we have already shown to be present in real-world biochemical networks operating under flux constraints. Our results demonstrate that the effective deficiency of real-world biochemical networks is smaller than the classical deficiency, indicating the effects of reaction directionality and flux bounds on the variation of the complex formation rate vector at steady state.

Fluxes of metabolic reactions represent the integrated outcome of transcription, translation, and post-translational modifications, and directly affect growth and fitness. However, fluxes of intracellular metabolic reactions cannot be directly measured, but are estimated via metabolic flux analysis (MFA) that integrates data on isotope labeling patterns of metabolites with metabolic models. While the application of metabolomics technologies in photosynthetic organisms have resulted in unprecedented data from 13CO2-labeling experiments, the bottleneck in flux estimation remains the application of isotopically nonstationary MFA (INST-MFA). INST-MFA entails fitting a (large) system of coupled ordinary differential equations, with metabolite pools and reaction fluxes as parameters. Here, we focus on the Calvin-Benson cycle (CBC) as a key pathway for carbon fixation in photosynthesizing organisms and ask if approaches other than classical INST-MFA can provide reliable estimation of fluxes for reactions comprising this pathway. Methods First, we show that flux estimation with the labeling patterns of all CBC intermediates can be formulated as a single constrained regression problem, avoiding the need for repeated simulation of time-resolved labeling patterns. Results We then compare the flux estimates of the simulation-free constrained regression approach with those obtained from the classical INST-MFA based on labeling patterns of metabolites from the microalgae Chlamydomonas reinhardtii, Chlorella sorokiniana and Chlorella ohadii under different growth conditions. Discussion Our findings indicate that, in data-rich scenarios, simulation-free regression-based approaches provide a suitable alternative for flux estimation from classical INST-MFA since we observe a high qualitative agreement (rs=0.89) to predictions obtained from INCA, a state-of-the-art tool for INST-MFA.

In this study, we explored the use of C. elegans to examine the toxicities of alkylating sulphur mustard analogues, specifically the monofunctional agent 2-chloroethyl-ethyl sulphide (CEES) and the bifunctional, crosslinking agent mechlorethamine (HN2). We exposed wild-type worms at different life cycle stages (from larvae L1 to adulthood day 10) to CEES or HN2 and scored their viability 24 h later. The susceptibility of C. elegans to CEES and HN2 paralleled that of human cells, with HN2 exhibiting higher toxicity than CEES, reflected in LC50 values in the high µM to low mM range. Importantly, the effects were dependent on the worms’ developmental stage as well as organismic age: the highest susceptibility was observed in L1, whereas the lowest was observed in L4 worms. In adult worms, susceptibility to alkylating agents increased with advanced age, especially to HN2. To examine reproductive effects, L4 worms were exposed to CEES and HN2, and both the offspring and the percentage of unhatched eggs were assessed. Moreover, germline apoptosis was assessed by using ced-1p::GFP (MD701) worms. In contrast to concentrations that elicited low toxicities to L4 worms, CEES and HN2 were highly toxic to germline cells, manifesting as increased germline apoptosis as well as reduced offspring number and percentage of eggs hatched. Again, HN2 exhibited stronger effects than CEES. Compound specificity was also evident in toxicities to dopaminergic neurons–HN2 exposure affected expression of dopamine transporter DAT-1 (strain BY200) at lower concentrations than CEES, suggesting a higher neurotoxic effect. Mechanistically, nicotinamide adenine dinucleotide (NAD+) has been linked to mustard agent toxicities. Therefore, the NAD+-dependent system was investigated in the response to CEES and HN2 treatment. Overall NAD+ levels in worm extracts were revealed to be largely resistant to mustard exposure except for high concentrations, which lowered the NAD+ levels in L4 worms 24 h post-treatment. Interestingly, however, mutant worms lacking components of NAD+-dependent pathways involved in genome maintenance, namely pme-2, parg-2, and sirt-2.1 showed a higher and compound-specific susceptibility, indicating an active role of NAD+ in genotoxic stress response. In conclusion, the present results demonstrate that C. elegans represents an attractive model to study the toxicology of alkylating agents, which supports its use in mechanistic as well as intervention studies with major strength in the possibility to analyze toxicities at different life cycle stages.

We classify daily ERA5 fields of convective indices according to CatRaRE, using an array of 13 statistical methods, consisting of 4 conventional (“shallow”) and 9 more recent deep machine learning (DL) algorithms; the classifiers are then applied to corresponding fields of simulated present and future atmospheres from the Coordinated Regional Climate Downscaling Experiment (CORDEX) project. The inherent uncertainty of the DL results from the stochastic nature of their optimization is addressed by employing an ensemble approach using 20 runs for each network. The shallow random forest method performs best with an equitable threat score (ETS) around 0.52, followed by the DL networks ALL-CNN and ResNet with an ETS near 0.48. Their success can be understood as a result of conceptual simplicity and parametric parsimony, which obviously best fits the relatively simple classification task. It is found that, on summer days, CatRaRE convective atmospheres over Germany occur with a probability of about 0.5. This probability is projected to increase, regardless of method, both in ERA5-reanalyzed and CORDEX-simulated atmospheres: for the historical period we find a centennial increase of about 0.2 and for the future period one of slightly below 0.1.

Methods Twenty-nine players participated in this study. Participants were randomly assigned to a FR training group, BR training group, and a control group. Results and discussion Within-group analysis indicated significant, small-to-large improvements in all performance tests (effect size [g] = 0.36 to 1.80), except 5-m forward sprint-time in the BR group and 5- and 10-m forward sprint-time in the FR group. However, the CG significantly decreased forward sprint performance over 10-m and 20-m (g = 0.28 to 0.50) with no changes in the other fitness parameters. No significant differences in the amount of change scores between the BR and FR groups were noted. Both training interventions have led to similar improvements in measures of muscle power, change of direction (CoD) speed, sprint speed either forward or backward, and repeated sprint ability (RSA) in young female handball players, though BR training may have a small advantage over FR training for 10-m forward sprint time and CoD speed, while FR training may provide small improvements over BR training for RSAbest. Practitioners are advised to consider either FR or BR training to improve various measures of physical fitness in young female handball players.

JF - Frontiers in psychology N2 - Introduction Early linguistic background, and in particular, access to language, lays the foundation of future reading skills in deaf and hard-of-hearing signers. The current study aims to estimate the impact of two factors – early access to sign and/or spoken language – on reading fluency in deaf and hard-of-hearing adult Russian Sign Language speakers. Methods In the eye-tracking experiment, 26 deaf and 14 hard-of-hearing native Russian Sign Language speakers read 144 sentences from the Russian Sentence Corpus. Analysis of global eye-movement trajectories (scanpaths) was used to identify clusters of typical reading trajectories. The role of early access to sign and spoken language as well as vocabulary size as predictors of the more fluent reading pattern was tested. Results Hard-of-hearing signers with early access to sign language read more fluently than those who were exposed to sign language later in life or deaf signers without access to speech sounds. No association between early access to spoken language and reading fluency was found. Discussion Our results suggest a unique advantage for the hard-of-hearing individuals from having early access to both sign and spoken language and support the existing claims that early exposure to sign language is beneficial not only for deaf but also for hard-of-hearing children.

The technique relies on inferring the phase dynamics model. The central assumption is that we observe the outputs of all network nodes. We distinguish between two cases. In the first one, the observed signals represent smooth oscillations, while in the second one, the data are pulse-like and can be viewed as point processes. For the first case, we discuss estimating the true phase from a scalar signal, exploiting the protophase-to-phase transformation. With the phases at hand, pairwise and triplet synchronization indices can characterize the undirected connectivity. Next, we demonstrate how to infer the general form of the coupling functions for two or three oscillators and how to use these functions to quantify the directional links. We proceed with a different treatment of networks with more than three nodes. We discuss the difference between the structural and effective phase connectivity that emerges due to high-order terms in the coupling functions. For the second case of point-process data, we use the instants of spikes to infer the phase dynamics model in the Winfree form directly. This way, we obtain the network’s coupling matrix in the first approximation in the coupling strength.

JF - Frontiers in psychology N2 - Introduction Vagally mediated heart rate variability is an index of autonomic nervous system activity that is associated with a large variety of outcome variables including psychopathology and self-regulation. While practicing heart rate variability biofeedback over several weeks has been reliably associated with a number of positive outcomes, its acute effects are not well known. As the strongest association with vagally mediated heart rate variability has been found particularly within the attention-related subdomain of self-regulation, we investigated the acute effect of heart rate variability biofeedback on attentional control using the revised Attention Network Test. Methods Fifty-six participants were tested in two sessions. In one session each participant received a heart rate variability biofeedback intervention, and in the other session a control intervention of paced breathing at a normal ventilation rate. After the biofeedback or control intervention, participants completed the Attention Network Test using the Orienting Score as a measure of attentional control. Results Mixed models revealed that higher resting baseline vagally mediated heart rate variability was associated with better performance in attentional control, which suggests more efficient direction of attention to target stimuli. There was no significant main effect of the intervention on attentional control. However, an interaction effect indicated better performance in attentional control after biofeedback in individuals who reported higher current stress levels. Discussion The results point to acute beneficial effects of heart rate variability biofeedback on cognitive performance in highly stressed individuals. Although promising, the results need to be replicated in larger or more targeted samples in order to reach stronger conclusions about the effects.

The preventive intake of probiotic lactobacilli has been shown to improve dysbiosis along with mood and metabolism. Yet, a potential role of Lactobacillus rhamnosus (Lacticaseibacillus rhamnosus 0030) (LR) in improving emotional behavior in established obesity and the underlying mechanisms are unknown. METHODS: Female and male C57BL/6N mice were fed a low-fat diet (10% kcal from fat) or high-fat diet (HFD) (45% kcal from fat) for 6 weeks, followed by daily oral gavage of vehicle or 1 3 10 8 colony-forming units of LR, and assessment of anxiety- and depressive-like behavior. Cecal microbiota composition was analyzed using 16S ribosomal RNA sequencing, plasma and cerebrospinal fluid were collected for metabolomic analysis, and gene expression of different brain areas was assessed using reverse transcriptase quantitative polymerase chain reaction. RESULTS: We observed that 12 weeks of HFD feeding induced hyperinsulinemia, which was attenuated by LR application only in female mice. On the contrary, HFD-fed male mice exhibited increased anxiety- and depressive-like behavior, where the latter was specifically attenuated by LR application, which was independent of metabolic changes. Furthermore, LR application restored the HFD-induced decrease of tyrosine hydroxylase, along with normalizing cholecystokinin gene expression in dopaminergic brain regions; both tyrosine hydroxylase and cholecystokinin are involved in signaling pathways impacting emotional disorders. CONCLUSIONS: Our data show that LR attenuates depressive-like behavior after established obesity, with changes in the dopaminergic system in male mice, and mitigates hyperinsulinemia in obese female mice.

A1 - Rosenblum, Michael T1 - Inferring oscillator's phase and amplitude response from a scalar signal exploiting test stimulation JF - New journal of physics : the open-access journal for physics N2 - The phase sensitivity curve or phase response curve (PRC) quantifies the oscillator's reaction to stimulation at a specific phase and is a primary characteristic of a self-sustained oscillatory unit. Knowledge of this curve yields a phase dynamics description of the oscillator for arbitrary weak forcing. Similar, though much less studied characteristic, is the amplitude response that can be defined either using an ad hoc approach to amplitude estimation or via the isostable variables. Here, we discuss the problem of the phase and amplitude response inference from observations using test stimulation. Although PRC determination for noise-free neuronal-like oscillators perturbed by narrow pulses is a well-known task, the general case remains a challenging problem. Even more challenging is the inference of the amplitude response. This characteristic is crucial, e.g. for controlling the amplitude of the collective mode in a network of interacting units-a task relevant to neuroscience. Here, we compare the performance of different techniques suitable for inferring the phase and amplitude response, particularly with application to macroscopic oscillators. We suggest improvements to these techniques, e.g. demonstrating how to obtain the PRC in case of stimuli of arbitrary shape. Our main result is a novel technique denoted by IPID-1, based on the direct reconstruction of the Winfree equation and the analogous first-order equation for isostable dynamics. The technique works for signals with or without well-pronounced marker events and pulses of arbitrary shape; in particular, we consider charge-balanced pulses typical in neuroscience applications. Moreover, this technique is superior for noisy and high-dimensional systems. Additionally, we describe an error measure that can be computed solely from data and complements any inference technique.

We present a dataset consisting of 6-minute walks under single- (only walking) and dual-task (walking while performing a cognitive task) conditions in unfatigued and fatigued states from sixteen healthy adults. Especially, nine IMUs were placed on the head, chest, lower back, wrists, legs, and feet to record under each of the above-mentioned conditions. The dataset also includes a rich set of spatio-temporal gait parameters that capture the aspects of pace, symmetry, and variability, as well as additional study-related information to support further analysis. This dataset can serve as a foundation for future research on gait monitoring in free-living environments.

Focus has been extensively studied in Yucatec, yet the incompatibility of object fronting and progressive aspect in Yucatec Maya remains understudied. Both our experimental results and our corpus study point in the direction that this incompatibility may very well be categorical. Theoretically, we take a progressive reading to be derived from an imperfectivity operator in combination with a singular operator, and we propose that this singular operator implicates the negation of event plurality, leading to an exhaustive interpretation which ranks below corrective focus on a contrastive focus scale. This means that, in a sentence with object focus fronting, the use of the marked auxiliary táan (as opposed to the more general k) would trigger two contrastive foci, which would be an unlikely and probably dispreferred speech act.

It incorporates automatic speech recognition (ASR) to provide therapist-independent feedback. The execution and effectiveness of a self-administered intervention with LingoTalk was explored in a case series study. Methods Three individuals with chronic aphasia participated in a highly individualized, supervised self-administered intervention lasting 3 weeks. The LingoTalk app closely monitored the frequency, intensity and progress of the intervention. Treatment efficacy was assessed using a multiple baseline design, examining both item-specific treatment effects and generalization to untreated items, an untreated task, and spontaneous speech. Results All participants successfully completed the intervention with LingoTalk, although one participant was not able to use the ASR feature. None of the participants fully adhered to the treatment protocol. All participants demonstrated significant and sustained improvement in the naming of practiced items, although there was limited evidence of generalization. Additionally, there was a slight reduction in word-finding difficulties during spontaneous speech. Discussion This small-scale study indicates that self-administered intervention with LingoTalk can improve oral naming of treated items. Thus, it has the potential to complement face-to-face speech-language therapy, such as within in a “flipped speech room” approach. The choice of feedback mode is discussed. Transparent progress monitoring of the intervention appears to positively influence patients' motivation.

Gerade deshalb ist es unabdingbar, Meinungsmacht einzelner Medienunternehmen zu verhindern und dadurch zur Meinungsvielfalt beizutragen. Diese bedeutende Aufgabe kommt der Medienkonzentrationskontrolle des Medienstaatsvertrages zu. Doch haben die digitalisierungsbedingten Veränderungen in der Medienlandschaft zu einem inkonsistenten Prüfungsregime der Medienkonzentrationskontrolle geführt, da medienrechtlich aktuell nicht alle für die Meinungsbildung relevanten Medienakteure ausreichend erfasst werden. Die Arbeit untersucht die Thematik im Kontext der nationalen sowie internationalen medien- und wettbewerbsrechtlichen Rahmenbedingungen. Basierend auf den dabei gewonnenen Erkenntnissen wird ein den aktuellen Erfordernissen entsprechender normativer Vorschlag unterbreitet. N2 - In the interest of democracy, individual media companies must be prevented from gaining opinion power. To this end, media concentration is regulated in accordance with the Interstate Media Treaty. However, recent developments in the media sector have led to an inconsistent regulatory regime, which no longer adequately covers all media players relevant to the formation of public opinion. This publication analyzes the issue in the context of both a media law and competition law framework and presents a legislative proposal suitable for restoring regulatory effectiveness KW - Deutschland KW - Regulierung KW - Medienangebot KW - Meinungsbildung KW - Massenmedien KW - Medienstaatsvertrag (2020 April 14) KW - Unternehmenskonzentration KW - Fusionskontrolle Y1 - 2024 SN - 978-3-428-19073-7 SN - 978-3-428-59073-5 U6 - https://doi.org/10.3790/978-3-428-59073-5 VL - 4 PB - Duncker & Humblot CY - Berlin ER - TY - JOUR A1 - Zhelavskaya, Irina A1 - Aseev, Nikita A1 - Shprits, Yuri T1 - A combined neural network‐ and physics‐based approach for modeling plasmasphere dynamics JF - JGR / AGU, American Geographical Union. Space Physics N2 - Abstract In recent years, feedforward neural networks (NNs) have been successfully applied to reconstruct global plasmasphere dynamics in the equatorial plane. These neural network‐based models capture the large‐scale dynamics of the plasmasphere, such as plume formation and erosion of the plasmasphere on the nightside. However, their performance depends strongly on the availability of training data. When the data coverage is limited or non‐existent, as occurs during geomagnetic storms, the performance of NNs significantly decreases, as networks inherently cannot learn from the limited number of examples. This limitation can be overcome by employing physics‐based modeling during strong geomagnetic storms. Physics‐based models show a stable performance during periods of disturbed geomagnetic activity if they are correctly initialized and configured. In this study, we illustrate how to combine the neural network‐ and physics‐based models of the plasmasphere in an optimal way by using data assimilation. The proposed approach utilizes advantages of both neural network‐ and physics‐based modeling and produces global plasma density reconstructions for both quiet and disturbed geomagnetic activity, including extreme geomagnetic storms. We validate the models quantitatively by comparing their output to the in‐situ density measurements from RBSP‐A for an 18‐month out‐of‐sample period from June 30, 2016 to January 01, 2018 and computing performance metrics. To validate the global density reconstructions qualitatively, we compare them to the IMAGE EUV images of the He+ particle distribution in the Earth's plasmasphere for a number of events in the past, including the Halloween storm in 2003.
