  abstract  = {Physical activity and exercise are effective approaches in prevention and therapy of multiple diseases. Although the specific characteristics of lengthening contractions have the potential to be beneficial in many clinical conditions, eccentric training is not commonly used in clinical populations with metabolic, orthopaedic, or neurologic conditions. The purpose of this pilot study is to investigate the feasibility, functional benefits, and systemic responses of an eccentric exercise program focused on the trunk and lower extremities in people with low back pain (LBP) and multiple sclerosis (MS). A six-week eccentric training program with three weekly sessions is performed by people with LBP and MS. The program consists of ten exercises addressing strength of the trunk and lower extremities. The study follows a four-group design (N = 12 per group) in two study centers (Israel and Germany): three groups perform the eccentric training program: A) control group (healthy, asymptomatic); B) people with LBP; C) people with MS; group D (people with MS) receives standard care physiotherapy. Baseline measurements are conducted before first training, post-measurement takes place after the last session both comprise blood sampling, self-reported questionnaires, mobility, balance, and strength testing. The feasibility of the eccentric training program will be evaluated using quantitative and qualitative measures related to the study process, compliance and adherence, safety, and overall program assessment. For preliminary assessment of potential intervention effects, surrogate parameters related to mobility, postural control, muscle strength and systemic effects are assessed. The presented study will add knowledge regarding safety, feasibility, and initial effects of eccentric training in people with orthopaedic and neurological conditions. The simple exercises, that are easily modifiable in complexity and intensity, are likely beneficial to other populations. Thus, multiple applications and implementation pathways for the herein presented training program are conceivable.},

  abstract  = {Microsaccades are very small, involuntary flicks in eye position that occur on average once or twice per second during attempted visual fixation. Microsaccades give rise to EMG eye muscle spikes that can distort the spectrum of the scalp EEG and mimic increases in gamma band power. Here we demonstrate that microsaccades are also accompanied by genuine and sizeable cortical activity, manifested in the EEG. In three experiments, high-resolution eye movements were corecorded with the EEG: during sustained fixation of checkerboard and face stimuli and in a standard visual oddball task that required the counting of target stimuli. Results show that microsaccades as small as 0.15° generate a field potential over occipital cortex and midcentral scalp sites 100 -140 ms after movement onset, which resembles the visual lambda response evoked by larger voluntary saccades. This challenges the standard assumption of human brain imaging studies that saccade-related brain activity is precluded by fixation, even when fully complied with. Instead, additional cortical potentials from microsaccades were present in 86\% of the oddball task trials and of similar amplitude as the visual response to stimulus onset. Furthermore, microsaccade probability varied systematically according to the proportion of target stimuli in the oddball task, causing modulations of late stimulus-locked event-related potential (ERP) components. Microsaccades present an unrecognized source of visual brain signal that is of interest for vision research and may have influenced the data of many ERP and neuroimaging studies.},

Therefore, the primary aim of the study is to acquire a deeper understanding of the dynamic process of resilience factors, coping strategies and psychosocial adjustment of adolescents living with chronic conditions. Methods/design We plan to consecutively recruit N = 450 adolescents (12-21 years) from three German patient registries for chronic conditions (type 1 diabetes, cystic fibrosis, or juvenile idiopathic arthritis). Based on screening for anxiety and depression, adolescents are assigned to two parallel groups - "inconspicuous" (PHQ-9 and GAD-7 < 7) vs. "conspicuous" (PHQ-9 or GAD-7 ≥ 7) - participating in a prospective online survey at baseline and 12-month follow-up. At two time points (T1, T2), we assess (1) intra- and interpersonal resiliency factors, (2) coping strategies, and (3) health-related quality of life, well-being, satisfaction with life, anxiety and depression. Using a cross-lagged panel design, we will examine the bidirectional longitudinal relations between resiliency factors and coping strategies, psychological adaptation, and psychosocial adjustment. To monitor Covid-19 pandemic effects, participants are also invited to take part in an intermediate online survey. Discussion The study will provide a deeper understanding of adaptive, potentially modifiable processes and will therefore help to develop novel, tailored interventions supporting a positive adaptation in youths with a chronic condition. These strategies should not only support those at risk but also promote the maintenance of a successful adaptation. Trial registration German Clinical Trials Register (DRKS), no. DRKS00025125.

  abstract  = {We examined individual differences in masked repetition priming by re-analyzing item-level response-time (RT) data from three experiments. Using a linear mixed model (LMM) with subjects and items specified as crossed random factors, the originally reported priming and word-frequency effects were recovered. In the same LMM, we estimated parameters describing the distributions of these effects across subjects. Subjects' frequency and priming effects correlated positively with each other and negatively with mean RT. These correlation estimates, however, emerged only with a reciprocal transformation of RT (i.e., -1/RT), justified on the basis of distributional analyses. Different correlations, some with opposite sign, were obtained (1) for untransformed or logarithmic RTs or (2) when correlations were computed using within-subject analyses. We discuss the relevance of the new results for accounts of masked priming, implications of applying RT transformations, and the use of LMMs as a tool for the joint analysis of experimental effects and associated individual differences.},

The results are evidence for a remarkable internationalization of psychological research, starting in the mid 1970s and increasing in rate at the beginning of the 1990s. This growth occurs against a constant number of articles with authors from the same country; it is not due to a concomitant increase in the number of co-authors per article. Thus, international collaboration in psychology is obviously on the rise.},

  abstract  = {Nikotin in den unterschiedlichsten Darreichungsformen verringert bei verschiedenen Spezies im r{\"a}umlichen Hinweisreizparadigma die Kosten invalider Hinweisreize. Welcher Teilprozess genau durch Nikotin beeinflusst wird, ist bislang nicht untersucht worden. Die g{\"a}ngige Interpretation ist, daß Nikotin das Losl{\"o}sen von Aufmerksamkeit von einem bisher beachteten Ort erleichtert. In f{\"u}nf Studien, drei elektrophysiologischen und zwei behavioralen wurden drei m{\"o}gliche Mechanismen der Nikotinwirkung an Nichtrauchern untersucht. Experiment 1 und 2 gingen der Frage nach, ob Nikotin eine Modulation sensorischer gain Kontrolle bewirkt. Dazu wurden ereigniskorrelierte Potentiale (EKP) im Posner-Paradigma erhoben und die Wirkung von Nikotin auf die aufmerksamkeitsassoziierten Komponenten P1 und N1 betrachtet. Nikotin verringerte die Kosten invalider Hinweisreize bei Aufmerksamkeitslenkung durch endogene Hinweisreize, nicht aber bei exogenen Hinweisreizen. Die P1 und N1 Komponenten zeigten sich unbeeinflusst von Nikotin, damit findet also die Annahme einer Wirkung auf sensorische Suppression keine Unterst{\"u}tzung. In Experiment 3 und 4 wurde untersucht, ob Nikotin einen Effekt auf kostentr{\"a}chtige unwillk{\"u}rliche Aufmerksamkeitsverschiebungen, Distraktionen, hat. In Experiment 3 wurden in einem r{\"a}umlichen Daueraufmerksamkeitsparadigma Distraktionen durch deviante Stimulusmerkmale ausgel{\"o}st und die Wirkung von Nikotin auf eine distraktionsassoziierte Komponente des EKP, die P3a, betrachtet. In Experiment 4 wurde in einem Hinweisreizparadigma durch zus{\"a}tzliche Stimuli eine Distraktion ausgel{\"o}st und die Nikotinwirkung auf die Reaktionszeitkosten untersucht. Nikotin zeigte keinen Einfluss auf Distraktionskosten in beiden Studien und auch keine Wirkung auf die P3a Komponente in Experiment 3. In Experiment 4 wurde zus{\"a}tzlich die Wirkung von Nikotin auf das Losl{\"o}sen von Aufmerksamkeit untersucht, indem die Schwierigkeit des Losl{\"o}sens variiert wurde. Auch hier zeigte sich keine Nikotinwirkung. Allerdings konnte in beiden Studien weder die h{\"a}ufig berichtete generelle Reaktionszeitverk{\"u}rzung noch die Verringerung der Kosten invalider Hinweisreize repliziert werden, so dass zum Einen keine Aussage {\"u}ber die Wirkung von Nikotin auf Distraktionen oder den Aufmerksamkeitslosl{\"o}seprozess gemacht werden k{\"o}nnen, zum Anderen sich die Frage stellte, unter welchen Bedingungen Nikotin einen differentiellen Effekt {\"u}berhaupt zeigt. Im letzten Experiment wurde hierzu die H{\"a}ufigkeit der Reaktionsanforderung einerseits und die zeitlichen Aspekte der Aufmerksamkeitslenkung andererseits variiert und der Effekt des Nikotins auf den Validit{\"a}tseffekt, die Reaktionszeitdifferenz zwischen valide und invalide vorhergesagten Zielreizen, betrachtet. Nikotin verringerte bei Individuen, bei denen Aufmerksamkeitslenkung in allen Bedingungen evident war, in der Tendenz den Validit{\"a}tseffekt in der ereignis{\"a}rmsten Bedingung, wenn nur selten willentliche Aufmerksamkeitsausrichtung notwendig war. Dies k{\"o}nnte als Hinweis gedeutet werden, dass Nikotin unter Bedingungen, die große Anforderungen an die Vigilanz stellen, die top-down Zuweisung von Aufmerksamkeitsressourcen unterst{\"u}tzt.},

  abstract  = {Glaciated high-alpine areas are fundamentally altered by climate change, with well-known implications for hydrology, e.g., due to glacier retreat, longer snow-free periods, and more frequent and intense summer rainstorms. While knowledge on how these hydrological changes will propagate to suspended sediment dynamics is still scarce, it is needed to inform mitigation and adaptation strategies. To understand the processes and source areas most relevant to sediment dynamics, we analyzed discharge and sediment dynamics in high temporal resolution as well as their patterns on several spatial scales, which to date few studies have done. We used a nested catchment setup in the Upper {\"O}tztal in Tyrol, Austria, where high-resolution (15 min) time series of discharge and suspended sediment concentrations are available for up to 15 years (2006-2020). The catchments of the gauges in Vent, S{\"o}lden and Tumpen range from 100 to almost 800 km2 with 10 \% to 30 \% glacier cover and span an elevation range of 930 to 3772 m a.s.l. We analyzed discharge and suspended sediment yields (SSY), their distribution in space, their seasonality and spatial differences therein, and the relative importance of short-term events. We complemented our analysis by linking the observations to satellite-based snow cover maps, glacier inventories, mass balances and precipitation data. Our results indicate that the areas above 2500 m a.s.l., characterized by glacier tongues and the most recently deglaciated areas, are crucial for sediment generation in all sub-catchments. This notion is supported by the synchronous spring onset of sediment export at the three gauges, which coincides with snowmelt above 2500 m but lags behind spring discharge onsets. This points at a limitation of suspended sediment supply as long as the areas above 2500 m are snow-covered. The positive correlation of annual SSY with glacier cover (among catchments) and glacier mass balances (within a catchment) further supports the importance of the glacier-dominated areas. The analysis of short-term events showed that summer precipitation events were associated with peak sediment concentrations and yields but on average accounted for only 21 \% of the annual SSY in the headwaters. These results indicate that under current conditions, thermally induced sediment export (through snow and glacier melt) is dominant in the study area. Our results extend the scientific knowledge on current hydro-sedimentological conditions in glaciated high-alpine areas and provide a baseline for studies on projected future changes in hydro-sedimentological system dynamics.},

The data recording setup and data analysis pipelines are both crucial aspects to effectively obtain relevant information from participants. Therefore, we performed a systematic review to provide a high-level overview of practices across various neurological disorders and highlight emerging trends. PRISMA-based literature searches were conducted through PubMed, Web of Science, and IEEE Xplore to identify publications in which original (i.e., newly recorded) datasets were collected. Disorders of interest were psychiatric as well as neurodegenerative disorders, such as bipolar disorder, depression, and stress, as well as amyotrophic lateral sclerosis amyotrophic lateral sclerosis, Alzheimer's, and Parkinson's disease, and speech impairments (aphasia, dysarthria, and dysphonia). Of the 43 retrieved studies, Parkinson's disease is represented most prominently with 19 discovered datasets. Free speech and read speech tasks are most commonly used across disorders. Besides popular feature extraction toolkits, many studies utilise custom-built feature sets. Correlations of acoustic features with psychiatric and neurodegenerative disorders are presented. In terms of analysis, statistical analysis for significance of individual features is commonly used, as well as predictive modeling approaches, especially with support vector machines and a small number of artificial neural networks. An emerging trend and recommendation for future studies is to collect data in everyday life to facilitate longitudinal data collection and to capture the behavior of participants more naturally. Another emerging trend is to record additional modalities to voice, which can potentially increase analytical performance.},

A paper-and-pencil questionnaire was given to parents of pediatric patients (<21 years) during the routine check-ups. The questionnaire contains self-constructed items assessing the frequency of healthcare appointments and cancellations, remote healthcare, and satisfaction with healthcare. In total, 905 parents participated in the T1D-sample, 175 in the obesity-sample, and 786 in the JIA-sample. In general, satisfaction with healthcare (scale: 0-10; 10 reflecting the highest satisfaction) was quite high (median values: T1D 10, JIA 10, obesity 8.5). The proportion of children and adolescents with canceled appointments was relatively small (T1D 14.1\%, JIA 11.1\%, obesity 20\%), with a median of 1 missed appointment, respectively. Only a few parents (T1D 8.6\%; obesity 13.1\%; JIA 5\%) reported obstacles regarding health services during the pandemic. To conclude, it seems that access to healthcare was largely preserved for children and adolescents with chronic health conditions during the COVID-19 pandemic in Germany.},
