N2 - There has been increasing interest in the spatial mapping of various perceptual and cognitive magnitudes, such as expanding the spatial-numerical association of response codes (SNARC) effect into domains outside of numerical cognition. Recently, De Tommaso and Prpic (Attention, Perception, & Psychophysics, 82, 2765-2773, 2020) reported in this journal that only fast tempos over 104 beats per minute have spatial associations, with more right-sided associations and faster responses for faster tempos. After discussing the role of perceived loudness and possible response strategies, we propose and recommend methodological improvements for further research.

A1 - Reich, Sebastian T1 - Spectral convergence of diffusion maps BT - Improved error bounds and an alternative normalization JF - SIAM journal on numerical analysis / Society for Industrial and Applied Mathematics N2 - Diffusion maps is a manifold learning algorithm widely used for dimensionality reduction. Using a sample from a distribution, it approximates the eigenvalues and eigenfunctions of associated Laplace-Beltrami operators. Theoretical bounds on the approximation error are, however, generally much weaker than the rates that are seen in practice. This paper uses new approaches to improve the error bounds in the model case where the distribution is supported on a hypertorus. For the data sampling (variance) component of the error we make spatially localized compact embedding estimates on certain Hardy spaces; we study the deterministic (bias) component as a perturbation of the Laplace-Beltrami operator's associated PDE and apply relevant spectral stability results. Using these approaches, we match long-standing pointwise error bounds for both the spectral data and the norm convergence of the operator discretization. We also introduce an alternative normalization for diffusion maps based on Sinkhorn weights. This normalization approximates a Langevin diffusion on the sample and yields a symmetric operator approximation. We prove that it has better convergence compared with the standard normalization on flat domains, and we present a highly efficient rigorous algorithm to compute the Sinkhorn weights.

Xavier A1 - Farina, Emanuele Paolo T1 - Dating individual quasars with the He II proximity effect JF - Monthly notices of the Royal Astronomical Society N2 - Constraints on the time-scales of quasar activity are key to understanding the formation and growth of supermassive black holes (SMBHs), quasar triggering mechanisms, and possible feedback effects on their host galaxies. However, observational estimates of this so-called quasar lifetime are highly uncertain (t(Q) similar to 10(4)-10(9) yr), because most methods are indirect and involve many model-dependent assumptions. Direct evidence of earlier activity is gained from the higher ionization state of the intergalactic medium (IGM) in the quasar environs, observable as enhanced Ly alpha transmission in the so-called proximity zone. Due to the similar to 30 Myr equilibration time-scale of He II in the z similar to 3 IGM, the size of the He II proximity zone depends on the time the quasar had been active before our observation t(on) <= t(Q), enabling up to +/- 0.2 dex precise measurements of individual quasar on-times that are comparable to the e-folding time-scale t(S) <= 44 Myr of SMBH growth. Here we present the first statistical sample of 13 quasars whose accurate and precise systemic redshifts allow for measurements of sufficiently precise He II quasar proximity zone sizes between similar or equal to 2 and similar or equal to 15 proper Mpc from science-grade Hubble Space Telescope (HST) spectra. Comparing these sizes to predictions from cosmological hydrodynamical simulations post-processed with 1D radiative transfer, we infer a broad range of quasar on-times from t(on) less than or similar to 1Myr to t(on) > 30 Myr that does not depend on quasar luminosity, black hole mass, or Eddington ratio. These results point to episodic quasar activity over a long duty cycle, but do not rule out substantial SMBH growth during phases of radiative inefficiency or obscuration.

However, whether people follow this recommendation substantially depends on their willingness to try unfamiliar foods, also referred to as food neophilia. This study aimed at comprehensively validating the German version of the Variety Seeking Tendency Scale (VARSEEK), a common instrument to assess food neophilia. Two independent sub-studies were conducted to examine the German VARSEEK's psychometric properties. Study 1 (N = 532, aged 18-91 years) and Study 2 (N = 468, aged 18-73 years) each comprised a German community sample. Data were collected both online and via a paper-pencil version. Whereas Study 1 included an EFA, Study 2 comprised a CFA, analyses of the VARSEEK's reliability and construct validity, and different explorative group comparisons. EFA and CFA results supported the original scale's unidimensionality. Internal consistency (alpha = .93) and test-retest reliability (r = .87) of the scale were high. VARSEEK scores were positively associated with openness, sensation seeking, and extraversion and negatively associated with food neophobia, general neophobia, and trait anxiety. Construct validity was further established by showing positive associations with ratings of familiarity with and willingness to try familiar and unfamiliar foods. Whereas group comparisons revealed no significant differences for sex, age, and weight status, analyses showed that people who belonged to the upper class were more food neophilic than those assigned to the lower and middle class. Findings further underscore that the German VARSEEK is a reliable and valid instrument for the assessment of food neophilia in the German population.

More knowledge is needed to understand how adolescents cope with cyberhate and how they can be supported when exposed. To this end, the present study investigated the associations between parental mediation of Internet use and adolescents' problem-focused coping strategies for hypothetical cyberhate victimization while considering family support as a moderator of these relationships. The sample consisted of self-reports of 5,960 adolescents between 12-18 years old (M=14.94; SD=1.61; females: 50.7%) from Cyprus, Germany, Greece, India, Spain, South Korea, and Thailand. A structural equation model was used to investigate the relationship among parental mediation, family support, and coping with cyberhate. Findings showed a positive relationship between instructive parental mediation and adolescents' problem-focused coping strategies, and a negative relationship between restrictive parental mediation and adolescents' capability to cope productively with cyberhate. In addition, family support strengthened the positive relationship between instructive parental mediation and adolescents' use of coping strategies and attenuated the negative relationship between restrictive parental mediation and adolescents' use of coping strategies. The findings highlight the need for parental education training and underscore the importance of family support for increasing adolescents' ability to cope productively with cyberhate.

El presente estudio investigó la relación entre la mediación parental en el uso de Internet y las estrategias de afrontamiento entre adolescentes centradas en el problema en una hipotética victimización en ciberodio, al tiempo que se consideró el apoyo familiar como moderador de estas relaciones. La muestra estuvo formada por 5.960 adolescentes de entre 12 y 18 años que completaron autoinformes (M=14,94; DE=1,61; mujeres: 50,7%) de Chipre, Alemania, Grecia, India, España, Corea del Sur y Tailandia. Se estimó un modelo de ecuaciones estructurales para investigar la relación entre mediación parental, apoyo social y afrontamiento. Se halló una relación positiva entre la mediación parental instructiva y el uso de estrategias de afrontamiento centradas en el problema y una relación negativa entre la mediación parental restrictiva y la capacidad de los adolescentes para afrontar de forma adecuada el ciberodio. Además, el apoyo familiar moderó estas relaciones, incrementando la relación entre mediación instructiva y afrontamiento y disminuyendo la relación entre mediación restrictiva y afrontamiento de ciberodio. Los hallazgos enfatizan la necesidad de proporcionar información a los padres y ponen de manifiesto la importancia de que las familias fomenten la habilidad de los adolescentes para afrontar de manera adecuada el ciberodio.

The hypothesis investigated was whether the OFC sensitivity to reward and nonreward is related to the severity of depressive symptoms. METHODS: Activations in the monetary incentive delay task were measured in the IMAGEN cohort at ages 14 years (n = 1877) and 19 years (n = 1140) with a longitudinal design. Clinically relevant subgroups were compared at ages 19 (high-severity group: n = 116; low-severity group: n = 206) and 14. RESULTS: The medial OFC exhibited graded activation increases to reward, and the lateral OFC had graded activation increases to nonreward. In this general population, the medial and lateral OFC activations were associated with concurrent depressive symptoms at both ages 14 and 19 years. In a stratified high-severity depressive symptom group versus control group comparison, the lateral OFC showed greater sensitivity for the magnitudes of activations related to nonreward in the high-severity group at age 19 (p = .027), and the medial OFC showed decreased sensitivity to the reward magnitudes in the high-severity group at both ages 14 (p = .002) and 19 (p = .002). In a longitudinal design, there was greater sensitivity to nonreward of the lateral OFC at age 14 for those who exhibited high depressive symptom severity later at age 19 (p = .003). CONCLUSIONS: Activations in the lateral OFC relate to sensitivity to not winning, were associated with high depressive symptom scores, and at age 14 predicted the depressive symptoms at ages 16 and 19. Activations in the medial OFC were related to sensitivity to winning, and reduced reward sensitivity was associated with concurrent high depressive symptom scores.

However, direct comparison of these materials in their efficiency of suppressing LiPSs shuttling is challenging, owing to the structural and morphological differences between individual materials. This study introduces a simple route to synthesize a series of sulfur host materials with the same yolk-shell nanospindle morphology but tunable compositions (Fe3O4, FeS, or FeS2), which allows for a systematic investigation into the specific effect of chemical composition on the electrochemical performances of Li-S batteries. Among them, the S/FeS2-C electrode exhibits the best performance and delivers an initial capacity of 877.6 mAh g(-1) at 0.5 C with a retention ratio of 86.7 % after 350 cycles. This approach can also be extended to the optimization of materials for other functionalities and applications.

Yet, genome-scale flux profiling remains a challenge in deploying these approaches to catalogue proxies for enzyme catalytic rates across organisms. Results: Here, we formulate a constraint-based approach, termed NIDLE-flux, to estimate fluxes at a genome-scale level by using the principle of efficient usage of expressed enzymes. Using proteomics data from Escherichia coli, we show that the fluxes estimated by NIDLE-flux and the existing approaches are in excellent qualitative agreement (Pearson correlation > 0.9). We also find that the maximal in vivo catalytic rates estimated by NIDLE-flux exhibits a Pearson correlation of 0.74 with in vitro enzyme turnover numbers. However, NIDLE-flux results in a 1.4-fold increase in the size of the estimated maximal in vivo catalytic rates in comparison to the contenders. Integration of the maximum in vivo catalytic rates with publically available proteomics and metabolomics data provide a better match to fluxes estimated by NIDLE-flux. Therefore, NIDLE-flux facilitates more effective usage of proteomics data to estimate proxies for kcatomes.

However, the current 3D cell culture approach is tedious and time-consuming with a low success rate and high batch-to-batch variability. Here, we explored the establishment of lung bud organoids by systematically adjusting the initial confluence levels and homogeneity of cell distribution. The efficiency of single cell seeding and clump seeding was compared. Instead of the traditional 3D culture, we established a 2.5D organoid culture to enable the direct monitoring of the internal structure via microscopy. It was found that the cell confluence and distribution prior to induction were two key parameters, which strongly affected hiPSC differentiation trajectories. Lung bud organoids with positive expression of NKX 2.1, in a single-cell seeding group with homogeneously distributed hiPSCs at 70% confluence (SC 70% hom) or a clump seeding group with heterogeneously distributed cells at 90% confluence (CL 90% het), can be observed as early as 9 days post induction. These results suggest that a successful lung bud organoid formation with single-cell seeding of hiPSCs requires a moderate confluence and homogeneous distribution of cells, while high confluence would be a prominent factor to promote the lung organoid formation when seeding hiPSCs as clumps. 2.5D organoids generated with defined culture conditions could become a simple, efficient, and valuable tool facilitating drug screening, disease modeling and personalized medicine.

JF - Linguistics vanguard : multimodal online journal N2 - In syntactic dependency trees, when arcs are drawn from syntactic heads to dependents, they rarely cross. Constraints on these crossing dependencies are critical for determining the syntactic properties of human language, because they define the position of natural language in formal language hierarchies. We study whether the apparent constraints on crossing syntactic dependencies in natural language might be explained by constraints on dependency lengths (the linear distance between heads and dependents). We compare real dependency trees from treebanks of 52 languages against baselines of random trees which are matched with the real trees in terms of their dependency lengths. We find that these baseline trees have many more crossing dependencies than real trees, indicating that a constraint on dependency lengths alone cannot explain the empirical rarity of crossing dependencies. However, we find evidence that a combined constraint on dependency length and the rate of crossing dependencies might be able to explain two of the most-studied formal restrictions on dependency trees: gap degree and well-nestedness.

A pyranopterin molybdenum cofactor (Moco) is the catalytic site and a heme b(5) group located in the N-terminal domain. The two domains are connected by a flexible linker region. Electrons produced at the Moco in sulfite oxidation, are relayed via heme b(5) to electron acceptors or an electrode surface. Inter-domain conformational changes between an open and a closed enzyme conformation, allowing "gated" electron transfer has been suggested. We first recorded cyclic voltammetry (CV) of hSO on single-crystal Au(111)-electrode surfaces modified by self-assembled monolayers (SAMs) both of a short rigid thiol, cysteamine and of a longer structurally flexible thiol, omega-amino-octanethiol (AOT). hSO on cysteamine SAMs displays a well-defined pair of voltammetric peaks around -0.207 V vs. SCE in the absence of sulfite substrate, but no electrocatalysis. hSO on AOT SAMs displays well-defined electrocatalysis, but only "fair" quality voltammetry in the absence of sulfite. We recorded next in situ scanning tunnelling spectroscopy (STS) of hSO on AOT modified Au(111)-electrodes, disclosing, a 2-5 % surface coverage of strong molecular scale contrasts, assigned to single hSO molecules, notably with no contrast difference in the absence and presence of sulfite. In situ STS corroborated this observation with a sigmoidal tunnelling current/overpotential correlation.

Around 10 % of the papers published on MIPs describe the recognition of proteins. The straightforward synthesis of MIPs is a significant advantage as compared with the preparation of enzymes or antibodies. MIPs have been synthesized from only one up to six functional monomers while proteins are made up of 20 natural amino acids. Furthermore, they can be synthesized against structures of low immunogenicity and allow multi-analyte measurements via multi-target synthesis. Electrochemical methods allow simple polymer synthesis, removal of the template and readout. Among the different sensor configurations electrochemical MIP-sensors provide the broadest spectrum of protein analytes. The sensitivity of MIP-sensors is sufficiently high for biomarkers in the sub-nanomolar region, nevertheless the cross-reactivity of highly abundant proteins in human serum is still a challenge. MIPs for proteins offer innovative tools not only for clinical and environmental analysis, but also for bioimaging, therapy and protein engineering.

The biosynthesis of tRNA sulfur modifications involves unique sulfur trafficking systems for the incorporation of sulfur atoms in different nucleosides of tRNA. One of the proteins that is involved in inserting the sulfur for 5-methylaminomethyl-2-thiouridine (mnm(5)s(2)U34) modifications in tRNAs is the TusA protein. TusA, however, is a versatile protein that is also involved in numerous other cellular pathways. Despite its role as a sulfur transfer protein for the 2-thiouridine formation in tRNA, a fundamental role of TusA in the general physiology of Escherichia coli has also been discovered. Poor viability, a defect in cell division, and a filamentous cell morphology have been described previously for tusA-deficient cells. In this report, we aimed to dissect the role of TusA for cell viability. We were able to show that the lack of the thiolation status of wobble uridine (U-34) nucleotides present on Lys, Gln, or Glu in tRNAs has a major consequence on the translation efficiency of proteins; among the affected targets are the proteins RpoS and Fis. Both proteins are major regulatory factors, and the deregulation of their abundance consequently has a major effect on the cellular regulatory network, with one consequence being a defect in cell division by regulating the FtsZ ring formation.
IMPORTANCE More than 100 different modifications are found in RNAs. One of these modifications is the mnm(5)s(2)U modification at the wobble position 34 of tRNAs for Lys, Gln, and Glu. The functional significance of U34 modifications is substantial since it restricts the conformational flexibility of the anticodon, thus providing translational fidelity. We show that in an Escherichia coli TusA mutant strain, involved in sulfur transfer for the mnm(5)s(2)U34 thio modifications, the translation efficiency of RpoS and Fis, two major cellular regulatory proteins, is altered. Therefore, in addition to the transcriptional regulation and the factors that influence protein stability, tRNA modifications that ensure the translational efficiency provide an additional crucial regulatory factor for protein synthesis.

The latter is then used to prove, in the asymptotic framework, excess risk upper bounds of the regularised Hilbert valued statistical learning rules under the τ-mixing assumption on the underlying training sample. These results (of the batch statistical setting) are then supplemented with the regret analysis over the classes of Sobolev balls of the type of kernel ridge regression algorithm in the setting of online nonparametric regression with arbitrary data sequences. Here, in particular, a question of robustness of the kernel-based forecaster is investigated. Afterwards, in the framework of sequential learning, the multi-armed bandit problem under $\cC-$mixing assumption on the arm's outputs is considered and the complete regret analysis of a version of Improved UCB algorithm is given. Lastly, probabilistic inequalities of the first part are extended to the case of deviations (both of Azuma-Hoeffding's and of Burkholder's type) to the partial sums of real-valued weakly dependent random fields (under the type of projective dependence condition).

Separating transient events from volcanic tremors can, therefore, contrib-ute to improving upon our understanding of the underlying physical processes. Exploiting the idea of harmonic-percussive separation in musical signal processing, we develop a method to extract the harmonic volcanic tremor signals and to detect tran-sient events from seismic recordings. Based on the similarity properties of spectrogram frames in the time-frequency domain, we decompose the signal into two separate spec-trograms representing repeating (harmonic) and nonrepeating (transient) patterns, which correspond to volcanic tremor signals and earthquake signals, respectively. We reconstruct the harmonic tremor signal in the time domain from the complex spectrogram of the repeating pattern by only considering the phase components for the frequency range in which the tremor amplitude spectrum is significantly contribut-ing to the energy of the signal. The reconstructed signal is, therefore, clean tremor signal without transient events. Furthermore, we derive a characteristic function suitable for the detection of tran-sient events (e.g., earthquakes) by integrating amplitudes of the nonrepeating spectro-gram over frequency at each time frame. Considering transient events like earthquakes, 78% of the events are detected for signal-to-noise ratio = 0.1 in our semisynthetic tests. In addition, we compared the number of detected earthquakes using our method for one month of continuous data recorded during the Holuhraun 2014-2015 eruption in Iceland with the bulletin presented in Agustsdottir et al. (2019). Our single station event detection algorithm identified 84% of the bulletin events. Moreover, we detected a total of 12,619 events, which is more than twice the number of the bulletin events.

These attitudes are generally conceptualized as constructivist and transmissive views on teaching and learning with constructivism often considered to be more desirable. In explicit measures, this can have drawbacks like socially desirable responding. It is for this reason that, in this study, we investigated implicit attitudes as well as explicit attitudes towards constructivism and transmission. N = 100 preservice teachers worked on a questionnaire and two Single-Target Implicit Association Tests (ST-IAT constructivism and ST-IAT transmission) before (T1) and after (T2) a single master’s semester. One group (n = 50) did student teaching while a second group (n = 50) took master’s courses. We evaluated preservice teachers’ views on teaching at the end of their masters’ studies. Participants agreed with transmission and constructivism (T1) on both an explicit and implicit level. Implicit measures seem to exceed explicit measures in differentially assessing constructivist and transmissive views on teaching and learning. After student teaching (T2), there was no overall effect of attitude development but changes in rank indicate that participants’ implicit attitudes towards constructivism and transmission developed differently for each individual.

Personen, die mit der chronischen Erkrankung HIV leben (PWH), müssen ihr Leben lang die sog. antiretrovirale Therapie (ART) einnehmen, um einen Ausbruch der Erkrankung in das Vollbild AIDS (Akquiriertes Immun-Defizienz-Syndrom) zu vermeiden. Gleichzeitig ist die ART und HIV selbst assoziiert mit dem Auftreten zusätzlicher Erkrankungen (Komorbiditäten) kardiovaskulärer oder psychologischer Natur. Die Prävalenz von Komorbiditäten und schlechter Lebensqualität ist im Vergleich zu HIV-negativen Personen deutlich höher. Methoden. Es wurden zwei Metaanalysen zu sportlicher Betätigung, PWH und (1) kardiovaskulären und (2) psychologischen Parametern sowie eine Querschnittsstudie (HIBES-Studie, HIV-Begleiterkrankungen und Sport) durchgeführt. Für die Auswertung der metaanalytischen Daten wurde der Review Manager 5.3, für die Auswertung der Daten der HIBES-Studie das Analyseprogramm „R“ verwendet. In den Metaanalysen wurden, neben den Hauptanalysen verschiedener Parameter, erstmals spezifische Subgruppenanalysen durchgeführt. Die HIBES-Studie untersuchte Unterschiede zwischen kumulativen (2-3 verschiedenen Sportarten pro Woche) und einfachen (eine Sportart pro Woche) Freizeitsport und analysiert die Zusammenhänge von Parametern des Freizeitsports (Trainingshäufigkeit, -Minuten und –Intensität), Komorbiditäten und der Lebensqualität. Ergebnisse. Ausdauer- und Krafttraining haben einen mittel-starken bis starken positiven Effekt auf die maximale Sauerstoffaufnahme (SMD= 0.66, p< .00001), den 6-Minuten-Walk-Test (6MWT) (SMD= 0.59, p= .02), die maximale Watt Zahl (SMD= 0.80, p= .009). Kein Effekt wurde bei der maximalen Herzfrequenz und dem systolischen sowie diastolischen Blutdruck gefunden. Subgruppenanalysen zu ≥3 Einheiten/Woche, ≥150 Min./Woche ergaben hohe Effektstärken in der maximalen Watt Zahl und 6MWT. Ausdauer- und Krafttraining zusammen mit Yoga haben einen starken Effekt auf Symptome der Depression (SMD= -0.84, p= .02) und Angststörungen (SMD= -1.23, p= .04). Die Subanalyse der Depression zu professioneller Supervision und sportlicher Betätigung wiesen einen sehr starken Effekt (SMD= -1.40, p= .03). Die HIBES-Studie wies ein sehr differenziertes Bild im Sportverhalten von PWH in Deutschland auf. 49% der Teilnehmer übten mehr als eine Sportart pro Woche aus. Es wurden keine Unterschiede zwischen kumuliertem (CTE) und einfachem Sport (STE) in der Lebensqualität gefunden. Die Freizeitsportparameter (Häufigkeiten/Woche, Minuten/Woche, Intensität/Woche) waren in der CTE-Gruppe deutlich höher als in der STE-Gruppe. Trainingsminuten und die -Intensität zeigten beim Vorhandensein einer Komorbidität einen großen Zusammenhang mit der Lebensqualität. Die Minuten und die Intensität des durchgeführten Sportes zeigten einen prädiktiven Zusammenhang mit der Lebensqualität. Konklusion: Sportliche Betätigung verbessert die maximale Sauerstoffaufnahme und Symptome der Depression und Angststörungen. Die Aussagekraft der Subanalysen ist aufgrund der geringen Studienzahl, vorsichtig zu interpretieren. Erhöhte Trainingsparameter finden sich eher bei PWH, die mehr als eine Sportart pro Woche treiben. Daher kann kumulierter Sport als mediierender Faktor zur Steigerung der Lebensqualität interpretiert werden; zumindest bei PWH mit einer psychologischen Komorbidität.

Jahrhunderts dar und entscheidet mit ihren Auswirkungen auf Leben, Umwelt und technischen Fortschritt über das Schicksal der kontinuierlich wachsenden Weltbevölkerung. Das Werk untersucht das gegenwärtige Rohstoffvölkerrecht, bestehend aus dem Grundsatz der ständigen Souveränität über natürliche Ressourcen, dem WTO-Recht, multilateralen Abkommen sowie Rohstoffkartellen wie der OPEC und kommt zu dem Ergebnis, dass sich der aktuelle Regelungsbestand auf – in der Regel unverbindliche – organisatorische Maßnahmen und Konsultationen beschränkt. Das internationale Wirtschaftsrecht verfolgt einen passiven Ansatz, der der großen Relevanz dieses völkerrechtlichen Teilgebiets nicht gerecht wird. Vor diesem Hintergrund werden sechs verschiedene juristische Lösungsstrategien erarbeitet und im Anschluss auf ihre politische Realisierbarkeit überprüft. Dabei wird insbesondere auf die Stellung der Entwicklungsländer eingegangen, die trotz ihres Rohstoffreichtums bisher nicht von diesem profitieren.

Increased surface melt may lower the reflectivity of the ice sheet surface and thereby increase melt rates: the so-called melt-albedo feedback describes this self-sustaining increase in surface melting. In order to test the effect of the melt-albedo feedback in a prognostic ice sheet model, we implement dEBM-simple, a simplified version of the diurnal Energy Balance Model dEBM, in the Parallel Ice Sheet Model (PISM). The implementation includes a simple representation of the melt-albedo feedback and can thereby replace the positive-degree-day melt scheme. Using PISM-dEBM-simple, we find that this feedback increases ice loss through surface warming by 60 % until 2300 for the high-emission scenario RCP8.5 when compared to a scenario in which the albedo remains constant at its present-day values. With an increase of 90 % compared to a fixed-albedo scenario, the effect is more pronounced for lower surface warming under RCP2.6. Furthermore, assuming an immediate darkening of the ice surface over all summer months, we estimate an upper bound for this effect to be 70 % in the RCP8.5 scenario and a more than 4-fold increase under RCP2.6. With dEBM-simple implemented in PISM, we find that the melt-albedo feedback is an essential contributor to mass loss in dynamic simulations of the Greenland Ice Sheet under future warming.

Vor allem Türkeistämmige blieben nach dem Anwerbestopp häufiger in Deutschland als die Arbeitskräfte aus anderen Ländern. Wie keine andere Stadt steht Berlin bis heute für die Einwanderung aus der Türkei. Stefan Zeppenfeld untersucht den Wandel der türkischen Arbeitswelten von ihren Anfängen in den 1960er Jahren bis zur Wiedervereinigung. Ausgehend von der »Gastarbeit« im industriellen Großbetrieb spürt er in seiner Studie am Beispiel West-Berlins dem Übergang in andere Branchen nach. Er zeigt, wie der öffentliche Dienst auch für Migrantinnen und Migranten attraktive Aufstiegsmöglichkeiten eröffnete, zeichnet den schwierigen Weg in die gewerbliche Selbstständigkeit nach und legt illegale Beschäftigungsformen als alternative Verdienstmöglichkeit offen. Damit bettet der Autor die Geschichte der türkischen Arbeitsmigration in die deutsche Zeitgeschichte ein.

In contrast to conventional high-speed reciprocal space-mapping setups, our approach reduces the measurement time drastically due to a fixed measurement geometry with a position-sensitive detector. This means that neither the incident (ω) nor the exit (2θ) diffraction angle is scanned during the strain assessment via x-ray diffraction. Shifts of diffraction peaks on the fixed x-ray area detector originate from an out-of-plane strain within the sample. Quantitative strain assessment requires the determination of a factor relating the observed shift to the change in the reciprocal lattice vector. The factor depends only on the widths of the peak along certain directions in reciprocal space, the diffraction angle of the studied reflection, and the resolution of the instrumental setup. We provide a full theoretical explanation and exemplify the concept with picosecond strain dynamics of a thin layer of NbO2.

The magnetic field and turbulence play important roles in many astrophysical mechanisms, including cosmic ray transport, star formation, etc. Therefore, measurements of magnetic field and turbulence information are crucial for the proper interpretation of astronomical observations. Nonetheless, the magnetic field observation is quite challenging, especially, there is not universal magnetic tracer for diffuse medium. Moreover, the modelling of turbulence can be oversimplified due to the lack of observational tools to diagnose the plasma properties of the turbulence in the galactic interstellar medium. The studies presented in this thesis have addressed these challenges by bridging the theoretical studies of magnetic field and turbulence with numerical simulations and observations. The following research are presented in this thesis. The first observational evidence of the novel magnetic tracer, ground state alignment (GSA), is discovered, revealing the three-dimensional magnetic field as well as 2 orders of magnitude higher precision comparing to previous observational study in the stellar atmosphere of the post-AGB 89 Herculis. Moreover, the application of GSA in the sub-millimeter fine-structure lines is comprehensively studied for different elements and with magnetohydrodynamic simulations. Furthermore, the influence of GSA effect on the spectroscopy is analyzed and it is found that measurable variation will be produced on the spectral line intensity and the line ratio without accounting for the optical pumping process or magnetic field. Additionally, a novel method to measure plasma modes in the interstellar medium, Signatures from Polarization Analysis (SPA), is proposed and applied to real observations. Magneto-sonic modes are discovered in different types of interstellar medium. An explanation is provided for the long-standing mystery, the origin of γ-ray enhanced emission “Cygnus Cocoon”, based on the comparison between the outcome of SPA and multi-waveband observational data. These novel methods have strong potentials for broader observational applications and will play crucial roles in future multi-wavelength astronomy. N2 - Das interstellare Medium ist magnetisiert und turbulent. Das Magnetfeld und die Turbulenz spielen eine wichtige Rolle in vielen astrophysikalischen Prozessen, unter anderem beim Transport kosmischer Strahlung, bei der Entstehung von Sternen usw. Daher sind Messungen des Magnetfelds und der Turbulenz entscheidend bei der korrekten Interpretation astronomischer Beobachtungen. Dennoch ist die Messung des astronomischen Magnetfeldes eine große Herausforderung, besonders da es keinen universellen magnetischen Tracer für diffuse Medien gibt. Außerdem kann es aufgrund des Mangels an geeigneten Beobachtungswerkzeugen für die Plasmaeigenschaften der galaktischen Turbulenz zu übermäßigen Vereinfachungen bei der Turbulenzmodellierung kommen. Die in dieser Arbeit vorgestellten Forschungsergebnisse beschäftigen sich mit diesen Herausforderungen; die Theorien des Magnetfeldes und der Turbulenz werden durch numerische Simulationen und Beobachtungen anwendbar gemacht. Die erste Anwendung eines neuen magnetischen Markers, Ground State Alignment (GSA, deutsch „Grundzustandsausrichtung“), wird vorgestellt. Dabei wird das dreidimensionale Magnetfeld in der Analyse von Beobachtungsdaten aus der stellaren Atmosphäre des post-AGB 89 Herculis um zwei Größenordnungen genauer bestimmt als bei den bisherigen Methoden. Zusätzlich wird die Anwendung von GSA bei der Analyse von sub-millimeter Feinstrukturlinien ausführlich für verschiedene Elemente mit Hilfe von magnetohydrodynamischen Simulationen getestet. Auch der Einfluss von GSA-Effekten auf spektroskopische Analysen wird untersucht; dabei stellt sich heraus, dass messbare Variationen in der Linienbreite und im Verhältnis der Linien verursacht werden, ohne dass optische Pumpprozesse oder das Magnetfeld berücksichtigt werden. Des Weiteren wird die Signatures from Polarization Analysis (SPA, deutsch „Signatur-aus-Polarisationsanalyse“) als neue Messmethode für Plasmamoden im galaktischen Medium vorgestellt und auf reale Beobachtungen angewandt. In verschiedenen galaktischen Medien werden magneto-akustische Moden gefunden. Durch den Vergleich von Ergebnissen der SPA mit Beobachtungsdaten aus verschiedenen elektromagnetischen Frequenzbereichen kann die bisher ungeklärte Herkunft der gammastrahlenverstärkten Emission „Cygnus Cocoon“ erklärt werden. Diese neuen Methoden haben das Potential für eine breitere Anwendung bei der Analyse von Beobachtungen und werden in der Zukunft eine wichtige Rolle in der Multiwellenlängen-Astronomie spielen.

This study report on designing a multifunctional soft polymer material that can address a number of operating requirements such as solvent resistance, reshaping ability, self-healing capability, fluorescence stimuli-responsivity, and anisotropic structural functions. The numerous functional abilities are associated to rhodium(I)-phosphine coordination bonds, which in a polymer network act with their dynamic and non-covalently bonded nature as multifunctional crosslinks. Reversible aggregation of coordination bonds leads to changes in fluorescence emission intensity that responds to chemical or mechanical stimuli. The fast dynamics and diffusion of rhodium-phosphine ions across and through contacting areas of the material provide for reshaping and self-healing abilities that can be further exploited for assembly of multiple pieces into complex forms, all without any loss to material-sensing capabilities.

T1 - "Out of Pocket" protein binding BT - a dilemma of epitope imprinted polymers revealed for human hemoglobin JF - Chemosensors N2 - The epitope imprinting approach applies exposed peptides as templates to synthesize Molecularly Imprinted Polymers (MIPs) for the recognition of the parent protein. While generally the template protein binding to such MIPs is considered to occur via the epitope-shaped cavities, unspecific interactions of the analyte with non-imprinted polymer as well as the detection method used may add to the complexity and interpretation of the target rebinding. To get new insights on the effects governing the rebinding of analytes, we electrosynthesized two epitope-imprinted polymers using the N-terminal pentapeptide VHLTP-amide of human hemoglobin (HbA) as the template. MIPs were prepared either by single-step electrosynthesis of scopoletin/pentapeptide mixtures or electropolymerization was performed after chemisorption of the cysteine extended VHLTP peptide. Rebinding of the target peptide and the parent HbA protein to the MIP nanofilms was quantified by square wave voltammetry using a redox probe gating, surface enhanced infrared absorption spectroscopy, and atomic force microscopy. While binding of the pentapeptide shows large influence of the amino acid sequence, all three methods revealed strong non-specific binding of HbA to both polyscopoletin-based MIPs with even higher affinities than the target peptides.

Three systems with targeted surface modification and functionalization have been designed and synthesized, involving modified perylenediimide doped silica-coated silver nanowires, polydopamine or TiO2 coated gold-palladium nanorods and thiolated poly(ethylene glycol) (PEG-SH)/dodecanethiol (DDT) modified silver nanospheres. Their possible applications as plasmonic resonators, chiral sensors as well as photo-catalysts have been studied. In addition, the interaction between silver nanospheres and 2,3,5,6-Tetrafluoro-7,7,8,8-tetracyanoquinodimethane (F4TCNQ) molecules has also been investigated in detail. In the first part of the thesis, surface modification on Ag nanowires (NWs) with optimized silica coating through a modified Stöber method has been firstly conducted, employing sodium hydroxide (NaOH) to replace ammonia solution (NH4OH). The coated silver nanowires with a smooth silica shell have been investigated by single-particle dark-field scattering spectroscopy, transmission electron microscopy and electron-energy loss spectroscopy to characterize the morphologies and structural components. The silica-coated silver nanowires can be further functionalized with fluorescent molecules in the silica shell via a facile one-step coating method. The as-synthesized nanowire is further coupled with a gold nanosphere by spin-coating for the application of the sub-diffractional chiral sensor for the first time. The exciton-plasmon-photon interconversion in the system eases the signal detection in the perfectly matched 1D nanostructure and contributes to the high contrast of the subwavelength chiral sensing for the polarized light. In the second part of the thesis, dumbbell-shaped Au-Pd nanorods coated with a layer of polydopamine (PDA) or titanium dioxide (TiO2) have been constructed. The PDA- and TiO2- coated Au-Pd nanorods show a strong photothermal conversion performance under NIR illumination. Moreover, the catalytic performance of the particles has been investigated using the reduction of 4-nitrophenol (4-NP) as the model reaction. Under light irradiation, the PDA-coated Au-Pd nanorods exhibit a superior catalytic activity by increasing the reaction rate constant of 3 times. The Arrhenius-like behavior of the reaction with similar activation energies in the presence and absence of light irradiation indicates the photoheating effect to be the dominant mechanism of the reaction acceleration. Thus, we attribute the enhanced performance of the catalysis to the strong photothermal effect that is driven by the optical excitation of the gold surface plasmon as well as the synergy with the PDA layer. In the third part, the kinetic study on the adsorption of 2,3,5,6-Tetrafluoro-7,7,8,8-tetracyanoquino-dimethane (F4TCNQ) on the surface of Ag nanoparticles (Ag NPs) in chloroform has been reported in detail. Based on the results obtained from the UV-vis-NIR absorption spectroscopy, cryogenic transmission electron microscopy (cryo-TEM), scanning nano-beam electron diffraction (NBED) and electron energy loss spectroscopy (EELS), a two-step interaction kinetics has been proposed for the Ag NPs and F4TCNQ molecules. It includes the first step of electron transfer from Ag NPs to F4TCNQ indicated by the ionization of F4TCNQ, and the second step of the formation of Ag-F4TCNQ complex. The whole process has been followed via UV-vis-NIR absorption spectroscopy, which reveals distinct kinetics at two stages: the instantaneous ionization and the long-term complex formation. The kinetics and the influence of the molar ratio of Ag NPs/F4TCNQ molecules on the interaction between Ag NPs and F4TCNQ molecules in the organic solution are reported herein for the first time. Furthermore, the control experiment with silica-coated Ag NPs indicates that the charge transfer at the surface between Ag NPs and F4TCNQ molecules has been prohibited by a silica layer of 18 nm.

Without noise this model was recently proposed as a generalization of the Kuramoto model and it was found that alignment of the velocities occurs discontinuously for arbitrarily small attractive coupling. Adding noise to the system resolves this singular limit and leads to a continuous transition, either to a directed collective motion or to center-of-mass rotations.

Particularly, they contribute to prevent and inhibit the hypercoagulation condition. The failure of polymeric implants and blood contacting devices is often related to hypercoagulation and microbial contamination. Here, bioactive sulfated biomacromolecules are mimicked by sulfation of poly(glycerol glycidyl ether) (polyGGE) films. Autoclaving, gamma-ray irradiation and ethylene oxide (EtO) gas sterilization techniques were applied to functionalized materials. The sulfate group density and hydrophilicity of sulfated polymers were decreased while chain mobility and thermal degradation were enhanced post autoclaving when compared to those after EtO sterilization. These results suggest that a quality control after sterilization is mandatory to ensure the amount and functionality of functionalized groups are retained.

Skin conductance response (SCR) was measured during each interaction. Perceived impressions of the interaction (i.e., friendliness, comfort, arousal) were measured per questionnaire after each interaction. Participants' demographics and their attitude towards robots were also considered. We found shorter SCR rise times in the being touched compared to the touching condition, possibly reflecting psychological alertness to the unpredictability of robot-initiated contacts. The hand condition had shorter rise times than the buttock condition. Most participants evaluated the hand condition as most friendly and comfortable and the robot-initiated interactions as most arousing. Interacting with Pepper improved attitudes towards robots. Our findings require future studies with larger samples and improved procedures. They have implications for robot design in all domains involving tactile interactions, such as caring and intimacy.

We found that the standard deviation of the horizontal-to-vertical Fourier spectral ratio at individual sites, that is single-station horizontal-to-vertical spectral ratio (HVSR) sigma sigma(HV,s), approximates the within-site variability in site response quantified using surface-to-borehole spectral ratios (for oscillator frequencies higher than the site fundamental frequency) or empirical ground-motion models. Based on this finding, we then utilize the single-station HVSR sigma as a convenient tool to study the site-response variability at 697 KiK-net and 1169 K-NET sites. Our results show that at certain frequencies, stiff, rough and shallow sites, as well as small and local events tend to have a higher sigma(HV,s). However, when being averaged over different sites, the single-station HVSR sigma, that is sigma(HV), increases gradually with decreasing frequency. In the frequency range of 0.25-25 Hz, sigma(HV) is centred at 0.23-0.43 in ln scales (a linear scale factor of 1.26-1.54) with one standard deviation of less than 0.1. sigma(HV) is quite stable across different tectonic regions, and we present a constant, as well as earthquake magnitude- and distance-dependent sigma(HV) models.

In the present study, a series of loading and unloading triaxial compression tests (20, 40 and 60 MPa) on granite specimens after exposure to different temperatures (20, 200, 300, 400, 500 and 600 degrees C) was carried out to quantify the combined effects of thermal treatment and loading/unloading stress conditions on granite strength and deformation. Changes in the microstructure of granite exposed to high temperatures were revealed by optical microscopy. The experimental results indicate that both, thermal treatment and loading/unloading stress conditions, degrade the mechanical behaviors and further decrease the carrying capacity of granite. The gradual degradation of the mechanical characteristics of granite after thermal treatment is mainly associated with the evolution of thermal micro-cracks based on optical microscopy observations. The unloading stress state induces the extension of tension cracks parallel to the axial direction, and thus, the mechanical properties are degraded. Temperatures above 400 degrees C have a more significant influence on the mechanical characteristics of granite than the unloading treatment, whereby 400 degrees C can be treated as a threshold temperature for the delineation of significant deterioration. This study is expected to support feasibility and risk assessments by means of providing data for analytical calculations and numerical simulations on granite exposed to high temperatures during geothermal energy extraction.

Today's youth form a crucial target group for intervening in unsustainable overconsumption habits and for setting the path and ideas on responsible living. This article explores young people's motivations for engaging in three behavioural patterns linked to anti-consumption (voluntary simplicity, collaborative consumption, and living within one's means) in relation to sustainability. Applying a qualitative approach, laddering interviews reveal the consequences and values behind the anti-consumption behaviours of young people of ages 14 to 24 according to a means-end chains analysis. The findings highlight potential for and the challenges involved in motivating young people to reduce material levels of consumption for the sake of sustainability. Related consumer policy tools from the fields of education and communication are identified. This article provides practical implications for policy makers, activists, and educators. Consumer policies may strengthen anti-consumption among young people by addressing individual benefits, enabling reflection on personal values, and referencing credible narratives. The presented insights can help give a voice to young consumers, who struggle to establish themselves as key players in shaping the future consumption regime.

BT - Or, "Soll am Europäischen Wesen die Staatenimmunität genesen"? T2 - Remedies against immunity? N2 - This chapter argues not only that there is no European Sonderweg (or ‘special way’) when it comes to the law of state immunity but that there ought not to be one. Debates within The Hague Conference on Private International Law in the late 1990s and those leading to the adoption of the 2002 UN Convention on Jurisdictional Immunities of States, as well as the development of the EU Brussels Regulation on Jurisdiction and Enforcement, as amended in 2015, all demonstrate that state immunity was not meant to be limited by such treaties but ‘safeguarded’. Likewise, there is no proof that regional European customary law limits state immunity when it comes to ius cogens violations, as Italy and (partly) Greece are the only European states denying state immunity in such cases while the European Court of Human Rights has, time and again, upheld a broad concept of state immunity. It therefore seems unlikely that in the foreseeable future a specific European customary law norm on state immunity will develop, especially given the lack of participation in such practice by those states most concerned by the matter, including Germany. This chapter considers the possible legal implications of the jurisprudence of the Italian Constitutional Court for European military operations (if such operations went beyond peacekeeping). These implications would mainly depend on the question of attribution: if one where to assume that acts undertaken within the framework of military operations led by the EU were to be, at least also, attributable to the troop-contributing member states, the respective troop-contributing state would be entitled to enjoy state immunity exactly to the same degree as in any kind of unilateral military operations. Additionally, some possible perspectives beyond Sentenza 238/2014 are examined, in particular concerning the redress awarded by domestic courts ‘as long as’ neither the German nor the international system grant equivalent protection to the victims of serious violations of international humanitarian law committed during World War II. In the author’s opinion, strengthening the jurisdiction of international courts and tribunals, bringing interstate cases for damages before the International Court of Justice, as well as providing for claims commissions where individual compensation might be sought for violations of international humanitarian law would be more useful and appropriate mechanisms than denying state immunity.

The sequences were assigned to diatoms that are common in the area and characteristic of cold water. SedaDNA allowed us to observe shifts of potential lineages from species of the genus Chaetoceros that can be related to different climatic phases, suggesting that pre-adapted ecotypes might have played a role in the long-term success of species in areas of changing environmental conditions. These sedaDNA results complement our understanding of the long-term history of diatom assemblages and their general relationship to environmental conditions of the past. Sea-ice diatoms (Pauliella taeniata [Grunow] Round & Basson, Attheya septentrionalis [ostrup] R. M. Crawford and Nitzschia frigida [Grunow]) detected during the late glacial and Younger Dryas are in agreement with previous sea-ice reconstructions. A positive correlation between pennate diatom richness and the sea-ice proxy IP25 suggests that sea ice fosters pennate diatom richness, whereas a negative correlation with June insolation and temperature points to unfavorable conditions during the Holocene. A sharp increase in proportions of freshwater diatoms at similar to 11.1 cal kyr BP implies the influence of terrestrial runoff and coincides with the loss of 42% of diatom sequence variants. We assume that reduced salinity at this time stabilized vertical stratification which limited the replenishment of nutrients in the euphotic zone.

Importantly, the photoinduced level shifts occur in the organic component, including the first molecular layer in direct contact with the perovskite. This is caused by charge-carrier accumulation within the organic semiconductor under illumination and the weak electronic coupling between the junction components.

These devices benefit from the suppression of free charge recombination with regard to the Langevin limit of charge encounter in a homogeneous medium. It is recognized that the main cause of suppressed free charge recombination is the reformation and resplitting of charge-transfer (CT) states at the interface between donor and acceptor domains. Here, we use kinetic Monte Carlo simulations to understand the interplay between free charge motion and recombination in an energetically disordered phase-separated donor-acceptor blend. We identify conditions for encounter-dominated and resplitting-dominated recombination. In the former regime, recombination is proportional to mobility for all parameters tested and only slightly reduced with respect to the Langevin limit. In contrast, mobility is not the decisive parameter that determines the nongeminate recombination coefficient, k(2), in the latter case, where k2 is a sole function of the morphology, CT and charge-separated (CS) energetics, and CT-state decay properties. Our simulations also show that free charge encounter in the phase-separated disordered blend is determined by the average mobility of all carriers, while CT reformation and resplitting involves mostly states near the transport energy. Therefore, charge encounter is more affected by increased disorder than the resplitting of the CT state. As a consequence, for a given mobility, larger energetic disorder, in combination with a higher hopping rate, is preferred. These findings have implications for the understanding of suppressed recombination in solar cells with nonfullerene acceptors, which are known to exhibit lower energetic disorder than that of fullerenes.

Prophylactic measures, such as the use of vaccines, are of great importance in reducing the use of antibiotics in livestock. These vaccines are mainly produced based on formaldehyde inactivation. However, the latter damages the recognition elements of the bacterial proteins and thus could reduce the immune response in the animal. An alternative inactivation method developed in this work is based on gentle photodynamic inactivation using carbon nanodots (CNDs) at excitation wavelengths λex > 290 nm. The photodynamic inactivation was characterized on the nonvirulent laboratory strain Escherichia coli K12 using synthesized CNDs. For a gentle inactivation, the CNDs must be absorbed into the cytoplasm of the E. coli cell. Thus, the inactivation through photoinduced formation of reactive oxygen species only takes place inside the bacterium, which means that the outer membrane is neither damaged nor altered. The loading of the CNDs into E. coli was examined using fluorescence microscopy. Complete loading of the bacterial cells could be achieved in less than 10 min. These studies revealed a reversible uptake process allowing the recovery and reuse of the CNDs after irradiation and before the administration of the vaccine. The success of photodynamic inactivation was verified by viability assays on agar. In a homemade flow photoreactor, the fastest successful irradiation of the bacteria could be carried out in 34 s. Therefore, the photodynamic inactivation based on CNDs is very effective. The membrane integrity of the bacteria after irradiation was verified by slide agglutination and atomic force microscopy. The method developed for the laboratory strain E. coli K12 could then be successfully applied to the important avian pathogens Bordetella avium and Ornithobacterium rhinotracheale to aid the development of novel vaccines.

How are subject positions determined by the subject’s relationship to money and work? How fair is a society that predicates social inclusion upon employment? And what happens when full employment is impossible? The volume traces how literary authors and social theorists have answered these questions in different social and historical contexts from the nineteenth century to the present day. The contributions confront the imperatives of productivity, notions of success and failure, the construction of work cultures and environments, the (in)visibility of certain labour groups, and the implications of the body as a productive site.

Diese sind jedoch keineswegs ausschließlich negativ zu betrachten, sondern erfüllen wichtige Funktionen, ohne die wir unser alltägliches Leben nicht bewältigen könnten. Welche Bedeutung diese Erkenntnis für das wissenschaftliche Denken und Handeln, aber auch für den Unterricht in Universität und Schule hat, ist kaum untersucht worden. Die Beiträger*innen des Bandes nehmen sich dieses Desiderats an und fragen nach den emotionalen Dimensionen von Forschung, Lehre und Unterricht.

T1 - Navigating Socialist Encounters BT - Moorings and (Dis)Entanglements between Africa and East Germany during the Cold War N2 - This edited volume examines entanglements and disentanglements between Africa and East Germany during and after the Cold War from a global history perspective. Extending the view beyond political elites, it asks for the negotiated and plural character of socialism in these encounters and sheds light on migration, media, development, and solidarity through personal and institutional agency. With its distinctive focus on moorings and unmoorings, the volume shows how the encounters, albeit often brief, significantly influenced both African and East German histories.

Offensichtlich haben Menschen das Bedürfnis, sich staunenswerte Wirklichkeiten vorzustellen. ‚Alternative Welten‘ sind nicht nur Fiktionen, sondern werden in den Wissenschaften rational diskutiert: Die Philosophie begann mit der These, dass hinter der hiesigen Welt ein Ideenreich sei. In der Modallogik wird ausgelotet, wie sich von ‚möglichen‘ Welten sprechen lässt. Stringtheoretiker errechnen, wie viele Dimensionen notwendig sind. Die Religionswissenschaft erforscht, welche Himmelsmodelle geglaubt werden. Der Sammelband bringt die verschiedenen Zugänge zusammen. Allen Ansätzen ist der Zweifel gemeinsam, dass die hiesige Welt nicht die einzige sei. N2 - The discourse about several worlds is richly illustrated by science fiction and computer games. It seems evident that people have the desire to imagine astounding realities. However, 'alternative worlds' are not only fictions, but are discussed rationally in the scientific community: Philosophy began with the thesis that behind the world here there is a world of ideas. Modal logic explores how one can speak of 'possible' worlds. String theorists calculate how many dimensions are necessary. Religious studies investigates which heavenly models are believed. This anthology brings the different approaches together. Common to all approaches is the doubt that this world in the here and now is not the only one.

In recent years, digital technologies have transformed business and society, impacting all sectors of the economy and a wide variety of areas of life. Digitization is leading to rapidly growing volumes of data with great economic potential. Data, in its raw or unstructured form, has become an important and valuable economic asset, and protection of raw data has become a crucial subject for the intellectual property community. As legislators struggle to develop a settled legal regime in this complex area, this invaluable handbook will offer a careful and dedicated analysis of the legal instruments and remedies, both existing and potential, that provide such protection across a wide variety of national legal systems. What’s in this book: Produced under the auspices of the International Association for the Protection of International Property (AIPPI), more than forty active specialists of the association from twenty-three countries worldwide contribute national chapters on the relevant law in their respective jurisdictions. The contributions thoroughly explain how each country approaches such crucial matters as the following: if there is any intellectual property right available to protect raw data; the nature of such intellectual property rights that exist in unstructured data; contracts on data and which legal boundaries stand in the way of contract drafting; liability for data products or services; and questions of international private law and cross-border portability. Each country’s rules concerning specific forms of data – such as data embedded in household appliances and consumer goods, criminal offence data, data relating to human genetics, tax and bank secrecy, medical records, and clinical trial data – are described, drawing on legislation, regulation, and case law. How this will help you: A matchless legal resource on one of the most important raw materials of the twenty-first century, this book provides corporate counsel, practitioners and policymakers working in the field of intellectual property rights, and concerned academics with both a broad-based global overview on emerging legal strategies in the protection of unstructured data and the latest information on existing legislation and regulation in the area.

Gegenüber dem Distanzsinn des Sehens wird mit dem Berühren eine größere Unmittelbarkeit assoziiert. Doch die Möglichkeit des Kontaktes ist von Beginn an prekär. Das Berühren kann sich selbst nicht berühren. In das Berühren schiebt sich ein Dazwischen, das den Entzug dieser ambivalenten Figur bedingt. Diese aporetische Bestimmung des Berührens begründet das Unternehmen des Bandes. Jeder Eintrag wiederholt eine Bewegung des Berührens: In einzelnen Text- oder Bildlektüren werden Spuren verfolgt, die das Berühren im stetigen Sich-Entziehen in seinen mannigfaltigen Nachbarschaften hinterlässt. Die einzelnen Einträge generieren sich aus diesen Lektüren. Dabei spielt die Nachbarschaft der Einträge selbst eine tragende Rolle.

Beck CY - München ET - 2 ER - TY - BOOK ED - Gentry, Gerad T1 - Kantian legacies in German idealism T3 - Routledge studies in nineteenth-century philosophy N2 - Scholarship on German Idealism typically couches the systems of Idealism in terms of a rejection of or departure from Kant's critical philosophy. The few accounts that do look to the positive influence of Kant on the Idealists typically focus on the perceived need among the Idealists to revise Kant's system due to various shortcomings arising from his dualism. This volume seeks to reverse this norm. It does this by bringing together an original set of critical reflections on the ways in which the German Idealists maintain specific and fundamental Kantian qualities in their own systems. At the same time, the aim of this volume is not a reduction of German Idealism to Kant's thought. Instead, this volume highlights a set of core ways in which the German Idealists retain specific, fundamentally Kantian principles and qualities. To that extent, this volume paves the way for new interpretations by laying the ground for identifying those significant components of German Idealism that can defensibly be called "Kantian.

Yet, scholars are becoming ever more aware of the need to merge them into a single field of Jewish Studies. This volume opens new perspectives and bridges traditional gaps. The authors are not simply contributing to their respective fields of Sephardic or Ashkenazic Studies. Rather, they all include both Sephardic and Ashkenazic perspectives as they reflect on different aspects of encounters and reconsider traditional narratives. Subjects range from medieval and early modern Sephardic and Ashkenazic constructions of identities, influences, and entanglements in the fields of religious art, halakhah, kabbalah, messianism, and charity to modern Ashkenazic Sephardism and Sephardic admiration for Ashkenazic culture. For reasons of coherency, the contributions all focus on European contexts between the fourteenth and the nineteenth centuries.
