In a unifying framework generalizing established theories we characterize under which conditions Joint Ownership of assets creates the best cooperation incentives in a partnership. We endogenise renegotiation costs and assume that they weakly increase with additional assets. A salient sufficient condition for optimal cooperation incentives among patient partners is if Joint Ownership is a Strict Coasian Institution for which transaction costs impede an efficient asset reallocation after a breakdown. In contrast to Halonen (2002) the logic behind our results is that Joint Ownership maximizes the value of the relationship and the costs of renegotiating ownership after a broken relationship.
Inflation and trading
(2024)
We study how investors respond to inflation combining a customized survey experiment with trading data at a time of historically high inflation. Investors' beliefs about the stock return-inflation relation are very heterogeneous in the cross section and on average too optimistic. Moreover, many investors appear unaware of inflation-hedging strategies despite being otherwise well-informed about inflation and asset returns. Consequently, whereas exogenous shifts in inflation expectations do not impact return expectations, information on past returns during periods of high inflation leads to negative updating about the perceived stock-return impact of inflation, which feeds into return expectations and subsequent actual trading behavior.
We educate investors with significant dividend holdings about the benefits of dividend reinvestment and the costs of misperceiving dividends as additional, free income. The intervention increases planned dividend reinvestment in survey responses. Using trading records, we observe a corresponding causal increase in dividend reinvestment in the field of roughly 50 cents for every euro received. This holds relative to their prior behavior and a placebo sample. Investors who learned the most from the intervention update their trading by the largest extent. The results suggest the free dividends fallacy is a significant source of dividend demand. Our study demonstrates that simple, targeted, and focused educational interventions can affect investment behavior.
Coming of voting age. Evidence from a natural experiment on the effects of electoral eligibility
(2024)
In recent years, several jurisdictions have lowered the voting age, with many more discussing it. Sceptics question whether young people are ready to vote, while supporters argue that allowing them to vote would increase their specific engagement with politics. To test the latter argument, we use a series of register-based surveys of over 10,000 German adolescents. Knowing the exact birthdates of our respondents, we estimate the causal effect of eligibility on their information-seeking behaviour in a regression discontinuity design. While eligible and non-eligible respondents do not differ in their fundamental political dispositions, those allowed to vote are more likely to discuss politics with their family and friends and to use a voting advice application. This effect appears to be stronger for voting age 16 than for 18. The right to vote changes behaviour. Therefore, we cannot conclude from the behaviour of ineligible citizens that they are unfit to vote.
Highlights
• Pathways for a circular economy towards the EU goals require policy support that, in turn, requires legitimacy.
• Legitimacy is often contested in the public discourse at all phases in the technological innovation system.
• Legitimacy remains poorly understood for ‘in-between’ technologies that struggle to move from the formative to the growth stage.
• The article explores legitimacy for chemical recycling primarily based on evidence from the UK, Germany, and Italy.
Abstract
The European Commission aims to increase the recycling of plastic packaging to 60% by 2025, requiring fundamental changes towards a more circular economy. Pathways for this transition require policy support that largely depends on their legitimacy in the public discourse. These normative aspects remain poorly understood for ‘in-between’ technologies, i.e., technologies that are no longer novel but struggle to move to the growth phase within the technological innovation system. Therefore, we ask: How do discourses shape technology legitimacy for in-between technologies? Drawing on the empirical example of chemical recycling, the analysis renders two principal findings. First, legitimising and delegitimising storylines present contesting views on in-between technologies regarding their technological aspects, environmental and social impacts, and economic and policy implications. Second, how discourses contribute to technology legitimacy depends on the actors and interests that drive the prevalent storylines in particular contexts.

• Germany plans more long-distances water transfers to secure drinking water supply.
• Long-distance water transfers can unfold lock-ins that limit adaptive water governance.
• Our interdisciplinary case study shows how lock-ins emerge over different spaces and times.
• Commercialisation of water but also local protests contributed to various lock-ins.
• We therefore call for context-specific assessments of potentials and risks of LDWT.
Abstract
Germany plans to expand water transfers over long distances in the light of numerous and pressing challenges for drinking water supply. Research on inter- and intrabasin water transfers warns, however, that major investments in large-scale infrastructure systems accompanied by institutional logics and political interests often lead to a so-called lock-in. As a consequence, long-distance water transfers can limit the potential for adaptive water governance in the involved supply areas over decades with negative impacts for people and the environment. By using a case study in Germany as an example, we researched when, where and how such lock-ins around long-distance water transfers emerge. In the infrastructural development of the Elbaue-Ostharz transfer system we found various lock-ins that overlap in space and time. Some are located at the centre others at the margins of the infrastructure and commercialization of the water sector as well as hydraulic and hygienic concerns interlock with local protests in a way that the expansion of the long-distance water transfer infrastructure is presented continuously as imperative. Our findings contribute to a relational understanding of lock-ins of long-distance water transfers as contingent and diverse processes. Given the widespread occurrence of lock-ins, we argue for a context-specific assessment of potentials and risks of long-distance water transfers in times of multiple crises.
How does the design of debt repayment schedules affect household borrowing? To answer this question, we exploit a Swedish policy reform that eliminated interest-only mortgages for loan-to-value ratios above 50%. We document substantial bunching at the threshold, leading to 5% lower borrowing. Wealthy borrowers drive the results, challenging credit constraints as the primary explanation. We develop a model to evaluate the mechanisms driving household behavior and find that much of the effect comes from households experiencing ongoing flow disutility to amortization payments. Our results indicate that mortgage contracts with low initial payments substantially increase household borrowing and lifetime interest costs.
This paper contributes a multivariate forecasting comparison between structural models and Machine-Learning-based tools. Specifically, a fully connected feed forward non-linear autoregressive neural network (ANN) is contrasted to a well established dynamic stochastic general equilibrium (DSGE) model, a Bayesian vector autoregression (BVAR) using optimized priors as well as Greenbook and SPF forecasts. Model estimation and forecasting is based on an expanding window scheme using quarterly U.S. real-time data (1964Q2:2020Q3) for 8 macroeconomic time series (GDP, inflation, federal funds rate, spread, consumption, investment, wage, hours worked), allowing for up to 8 quarter ahead forecasts. The results show that the BVAR improves forecasts compared to the DSGE model, however there is evidence for an overall improvement of predictions when relying on ANN, or including them in a weighted average. Especially, ANN-based inflation forecasts improve other predictions by up to 50%. These results indicate that nonlinear data-driven ANNs are a useful method when it comes to macroeconomic forecasting.
Central bank intervention in the form of quantitative easing (QE) during times of low interest rates is a controversial topic. The author introduces a novel approach to study the effectiveness of such unconventional measures. Using U.S. data on six key financial and macroeconomic variables between 1990 and 2015, the economy is estimated by artificial neural networks. Historical counterfactual analyses show that real effects are less pronounced than yield effects.
Disentangling the effects of the individual asset purchase programs, impulse response functions provide evidence for QE being less effective the more the crisis is overcome. The peak effects of all QE interventions during the Financial Crisis only amounts to 1.3 pp for GDP growth and 0.6 pp for inflation respectively. Hence, the time as well as the volume of the interventions should be deliberated.
When estimating misspecified linear factor models for the cross-section of expected returns using GMM, the explanatory power of these models can be spuriously high when the estimated factor means are allowed to deviate substantially from the sample averages. In fact, by shifting the weights on the moment conditions, any level of cross-sectional fit can be attained. The mathematically correct global minimum of the GMM objective function can be obtained at a parameter vector that is far from the true parameters of the data-generating process. This property is not restricted to small samples, but rather holds in population. It is a feature of the GMM estimation design and applies to both strong and weak factors, as well as to all types of test assets.
Highlights
• We present a novel alternative to the die-in-the-cup experiment.
• Participants’ payoffs depend on their reported mothers’ birthdays.
• We find that subjects lied to obtain real monetary payoffs.
• The extent of lying is small and insensitive to several design variations.
Abstract
We ask a representative sample of German household decision-makers to enter their mother's birthday, with potential payments depending on the month and the day they state. Thus, we create an incentive to lie. Compared to the die-under-the-cup experiment, our alternative has a lower probability that the income-maximizing outcome is true. Furthermore, it is better suited for online surveys and samples in which gambling is socially stigmatized. We conduct different variations of this game to crystalize design recommendations for researchers interested in our tool. Participants lied to receive higher payoffs, but only with real monetary incentives and only to a relatively small extent. Our results are largely insensitive to several design elements that we vary, such as the probability of being paid and the magnitude of the payoffs.
Neanderthal diet has been on the spotlight of paleoanthropological research for many years. The majority of studies that tried to reconstruct the diet of Neanderthals were based on the analysis of zooarchaeological remains, stable isotopes, dental calculus and dental microwear patterns. In the past few years, there have been a few studies that linked dental macrowear patterns of Neanderthals and modern humans to diet and cultural habits. However, they mostly focused on maxillary molars. Although mandibular molars have been widely used in microwear dietary research, little is known about their usage at the macroscopic scale to detect information about human subsistence strategies. In this study, we compare the macrowear patterns of Neanderthal (NEA), fossil Homo sapiens (FHS), modern hunter-gatherers (MHG), pastoralists, early farmers and Australian Aborigines from Yuendumu mandibular molars in order to assess their utility in collecting any possible information about dietary and cultural habits among diverse human groups. We use the occlusal fingerprint analysis method, a quantitative digital approach that has been successfully employed to reconstruct the diet of living non-human primates and past human populations. Our results show macrowear pattern differences between meat-eater MHG and EF groups. Moreover, while we did not find eco-geographical differences in the macrowear patterns of the fossil sample, we found statistically significant differences between NEA and FHS inhabiting steppe/coniferous forest. This latter result could be associated with the use of distinct technological complexes in these two species, which ultimately could have allowed modern humans to exploit natural resources in a different way compared to NEA.
Highlights
• Since there is only a low level of evidence, it is difficult to agree on state-of-the-art standards or to provide recommendations and guidelines.
• The value of combining several monitoring devices for dual or triple guidance must be challenged.
• The principle of fascial plane blocks is suitable to avoid traumatic needle-to-nerve contact. However, local toxicity must be regarded as a possible mechanism for nerve injuries.
• Block procedures might be conducted during sedation or general anesthesia when considering the individual patients' clinical situations and the expertise of the anesthesiologist.
• The quality of ultrasound equipment and education provided by the corresponding anesthesia department is highly relevant
We study the many implications of the Eurosystem collateral framework for corporate bonds. Using data on the evolving collateral eligibility list, we identify the first inclusion dates of bonds and issuers and use these events to find that the increased supply and demand for pledgeable collateral following eligibility (a) increases activity in the corporate securities lending market, (b) lowers eligible bond yields, and (c) affects bond liquidity. Thus, corporate bond lending relaxes the constraint of limited collateral supply and thereby improves market functioning.
Does political conflict with another country influence domestic consumers' daily consumption choices? We exploit the volatile US-China relations in 2018 and 2019 to analyze whether US consumers reduce their visits to Chinese restaurants when bilateral relations deteriorate. We measure the degree of political conflict through negativity in media reports and rely on smartphone location data to measure daily visits to over 190,000 US restaurants. A deterioration in US-China relations induces a significant decline in visits not only to Chinese but also to other foreign ethnic restaurants, while visits to typical American restaurants increase. We identify consumers' age, race, and cultural openness to moderate the strength of this ethnocentric effect.
This paper empirically analyses whether post-global financial crisis regulatory reforms have created appropriate incentives to voluntarily centrally clear over-the-counter (OTC) derivative contracts. We use confidential European trade repository data on single-name sovereign credit default swap (CDS) transactions and show that both seller and buyer manage counterparty exposures and capital costs, strategically choosing to clear when the counterparty is riskier. The clearing incentives seem particularly responsive to seller credit risk, which is in line with the notion that counterparty credit risk (CCR) is asymmetric in CDS contracts. The riskiness of the underlying reference entity also impacts the decision to clear as it affects both CCR capital charges for OTC contracts and central counterparty clearing house (CCP) margins for cleared contracts. Lastly, we find evidence that when a transaction helps netting positions with the CCP and hence lower margins, the likelihood of clearing is higher.

• Out of the six edible pumpkin seeds found in Cameroonian C. sativus showed most potent anti-proliferative effects on prostate cells.
• Its oil conserved almost all the effects of raw seeds and prevented benign prostatic hyperplasia (BPH).
• It exhibited potent anti-inflammatory activities in rat with BPH.
Abstract
Pumpkin seeds are claimed to treat prostate tumour/cancer. The in vitro (ability to inhibit cell growth through MTT assay) and in vivo (ability to prevent testosterone-induced BPH in rats at the doses of 125, 250, 500 and 1000 mg/kg BW) of six edible pumpkin seeds found in Cameroonian were assessed. The endpoints were cell growth arrest, prostate mass and volume, prostatic epithelium height, prostatic proteins, prostate specific antigen (PSA) and inflammatory cytokines. In vitro, C. sativus seeds exhibited the most potent antiproliferative effects on DU145 and PC3 prostate cancer cells and its oil conserved almost all the effects of raw seeds. Further, it prevented the increased of prostate relative mass and volume, prostate epithelium height, PSA and testosterone dose-dependently compared to normal rats. This effect is thought to be mediated through antiandrogenic, estrogenic and anti-inflammatory activities, evidenced by a decreased in IL-1β, IL-6 and TNFα level. Overall, this results justify its traditional use.
The 2011 Arab Spring marked the opening of the Central Mediterranean Route for irregular border crossings between Libya and Italy, which produced heterogeneous reductions of bilateral smuggling distances between country pairs in the Mediterranean region. We exploit this source of spatial and temporal variation in bilateral distance along land and sea routes to estimate the elasticity of irregular migration intentions for African and Near East countries. We estimate an elasticity of migration intentions to smuggling distances exceeding −3, mainly driven by countries with weak rule of law and high internet penetration. Our findings are consistent across irregular migration measures both at the aggregate and individual levels. We show that irregular migration elasticity is higher for youth, relatively skilled individuals and those with an informative advantage (having a social network abroad or a mobile phone).

• We present the first results of a deep learning model based on a convolutional neural network for earthquake magnitude estimation, using HR-GNSS displacement time series.
• The influence of different dataset configurations, such as station numbers, epicentral distances, signal duration, and earthquake size, were analyzed to figure out how the model can be adapted to various scenarios.
• The model was tested using real data from different regions and magnitudes, resulting in the best cases with 0.09 ≤ RMS ≤ 0.33.
Abstract
High-rate Global Navigation Satellite System (HR-GNSS) data can be highly useful for earthquake analysis as it provides continuous high-frequency measurements of ground motion. This data can be used to analyze diverse parameters related to the seismic source and to assess the potential of an earthquake to prompt strong motions at certain distances and even generate tsunamis. In this work, we present the first results of a deep learning model based on a convolutional neural network for earthquake magnitude estimation, using HR-GNSS displacement time series. The influence of different dataset configurations, such as station numbers, epicentral distances, signal duration, and earthquake size, were analyzed to figure out how the model can be adapted to various scenarios. We explored the potential of the model for global application and compared its performance using both synthetic and real data from different seismogenic regions. The performance of our model at this stage was satisfactory in estimating earthquake magnitude from synthetic data with 0.07 ≤ RMS ≤ 0.11. Comparable results were observed in tests using synthetic data from a different region than the training data, with RMS ≤ 0.15. Furthermore, the model was tested using real data from different regions and magnitudes, resulting in the best cases with 0.09 ≤ RMS ≤ 0.33, provided that the data from a particular group of stations had similar epicentral distance constraints to those used during the model training. The robustness of the DL model can be improved to work independently from the window size of the time series and the number of stations, enabling faster estimation by the model using only near-field data. Overall, this study provides insights for the development of future DL approaches for earthquake magnitude estimation with HR-GNSS data, emphasizing the importance of proper handling and careful data selection for further model improvements.
Upon infection of host cells, Legionella pneumophila releases a multitude of effector enzymes into the cells cytoplasm that hijack a plethora of cellular activities, including the hosts ubiquitination pathways. Effectors belonging to the SidE-family are involved in non-canonical serine phosphoribosyl ubiquitination of host substrate proteins contributing to the formation of a Legionella-containing vacuole that is crucial in the onset of Legionnaires’ disease. This dynamic process is reversed by effectors called Dups that hydrolyse the phosphodiester in the phosphoribosyl ubiquitinated protein. We installed reactive warheads on chemically prepared ribosylated ubiquitin to generate a set of probes targeting these Legionella enzymes. In vitro tests on recombinant DupA revealed that a vinyl sulfonate warhead was most efficient in covalent complex formation. Mutagenesis and x-ray crystallography approaches were used to identify the site of covalent crosslinking to be an allosteric cysteine residue. The subsequent application of this probe highlights the potential to selectively enrich the Dup enzymes from Legionella-infected cell lysates.
The epitranscriptome embodies many new and largely unexplored functions of RNA. A significant roadblock hindering progress in epitranscriptomics is the identification of more than one modification in individual transcript molecules. We address this with CHEUI (CH3 (methylation) Estimation Using Ionic current). CHEUI predicts N6-methyladenosine (m6A) and 5-methylcytidine (m5C) in individual molecules from the same sample, the stoichiometry at transcript reference sites, and differential methylation between any two conditions. CHEUI processes observed and expected nanopore direct RNA sequencing signals to achieve high single-molecule, transcript-site, and stoichiometry accuracies in multiple tests using synthetic RNA standards and cell line data. CHEUI’s capability to identify two modification types in the same sample reveals a co-occurrence of m6A and m5C in individual mRNAs in cell line and tissue transcriptomes. CHEUI provides new avenues to discover and study the function of the epitranscriptome.
Microbial rhodopsins are omnipresent on Earth, however the vast majority of them remain uncharacterized. Here we describe a new rhodopsin clade from cold-adapted organisms and cold environments, such as glaciers, denoted as CryoRhodopsins (CryoRs). Our data suggest that CryoRs have photosensory activity. A distinguishing feature of the clade is the presence of a buried arginine residue close to the cytoplasmic face of its members. Combining single-particle cryo-electron microscopy and X-ray crystallography with the rhodopsin activation by light, we demonstrate that the arginine stabilizes a strongly blue-shifted intermediate of an extremely slow CryoRhodopsin photocycle. Together with extensive spectroscopic characterization, our investigations on CryoR1 and CryoR2 proteins reveal mechanisms of photoswitching in the newly identified clade and demonstrate principles of the adaptation of these rhodopsins to low temperatures.
Nuclear pore complexes (NPCs) constitute giant channels within the nuclear envelope that mediate nucleocytoplasmic exchange. NPC diameter is thought to be regulated by nuclear envelope tension, but how such diameter changes are physiologically linked to cell differentiation, where mechanical properties of nuclei are remodeled and nuclear mechanosensing occurs, remains unstudied. Here we used cryo-electron tomography to show that NPCs dilate during differentiation of mouse embryonic stem cells into neural progenitors. In Nup133-deficient cells, which are known to display impaired neural differentiation, NPCs however fail to dilate. By analyzing the architectures of individual NPCs with template matching, we revealed that the Nup133-deficient NPCs are structurally heterogeneous and frequently disintegrate, resulting in the formation of large nuclear envelope openings. We propose that the elasticity of the NPC scaffold mechanically safeguards the nuclear envelope. Our studies provide a molecular explanation for how genetic perturbation of scaffolding components of macromolecular complexes causes tissue-specific phenotypes.
Hurd (1952) separated Pepsis cerberus Lucas from P. elegans Lepeletier (Hymenoptera: Pompilidae: Pepsinae: Pepsini) based on external morphology and biogeography. Vardy (2005) synonymized the familiar and historically well-documented P. cerberus and P. elegans, combining these Nearctic taxa with several Neotropical variants in an extremely broad definition of P. menechma Lepeletier. In doing so, Vardy (2005) breached the principle of nomenclatural stability. He ignored the prevailing usage and clearly violated articles 23.2, 23.3 and 23.9.1.2 of the ICZN (1999). Morphological differences, ecological divergence, and narrow sympatric geographic distribution of P. cerberus and P. elegans contradict Vardy (2005) and justify full species status (Kurczewski 2023a). Furthermore, we propose the removal of the two species from the P. menechma list of synonyms and recommend full species reinstatement as Pepsis cerberus, restored status and Pepsis elegans, restored status. Pepsis menechma becomes a senior synonym of P. elegans. Morphometric re-examination and statistical analysis of P. cerberus and P. elegans structural features strongly support their reinstatement. Quantitative measurement of 10 parasitoid-related morphological characteristics of the females revealed the two species differ significantly in frons width/head width, head length/head width, vertex length/head width, vertex length/head length, flagellomere 1 length/flagellomere 1 width, forewing length/mesosoma width, and hind tibial inner spur length/hind basitarsus length. Pepsis cerberus and P. elegans females are structurally and statistically similar in gena-postgena corner radius, fore femur width/mesosoma width, and number of hind tibial serrations.

A new species of Paranthrene Hübner (Lepidoptera: Sesiidae) from the northern midwest United States
(2024)
A clearwing moth species, Paranthrene sogaardi Taft and Smith, 2024, new species, is described from Michigan and Minnesota. The recognition of this new species is based on a phylogeny estimated from mitochondrial cytochrome oxidase I and wingless DNA sequences of 25 specimens representing all Paranthrene Hübner species including individuals from various locations. Paranthrene sogaardi new species was monophyletic and differed from Paranthrene tabaniformis Rottenburg, 1775 by a mean of 7.6% COI pairwise “p” distance, coloration, and genitalic morphology.

The geographic distributions of three large wasps, Sphecius speciosus (Drury), Stictia carolina Fabricius and Stizus brevipennis Walsh (Hymenoptera: Crabronidae), occurring in Arkansas are defined using museum specimens and three internet-based data platforms. The internet-based data platforms generally provided more county location records than museum records. Using data from internet sources for easily identified species can better serve to illustrate the known distributions for some species thus making for a powerful tool elucidating distributional patterns and conservation planning.

Viruses that carry a positive-sense, single-stranded (+ssRNA) RNA translate their genomes soon after entering the host cell to produce viral proteins, with the exception of retroviruses. A distinguishing feature of retroviruses is reverse transcription, where the +ssRNA genome serves as a template to synthesize a double-stranded DNA copy that subsequently integrates into the host genome. As retroviral RNAs are produced by the host cell transcriptional machinery and are largely indistinguishable from cellular mRNAs, we investigated the potential of incoming retroviral genomes to directly express proteins. Here we show through multiple, complementary methods that retroviral genomes are translated after entry. Our findings challenge the notion that retroviruses require reverse transcription to produce viral proteins. Synthesis of retroviral proteins in the absence of productive infection has significant implications for basic retrovirology, immune responses and gene therapy applications.
Bipolar disorder (BD) is a heritable mental illness with complex etiology. While the largest published genome-wide association study identified 64 BD risk loci, the causal SNPs and genes within these loci remain unknown. We applied a suite of statistical and functional fine-mapping methods to these loci, and prioritized 22 likely causal SNPs for BD. We mapped these SNPs to genes, and investigated their likely functional consequences by integrating variant annotations, brain cell-type epigenomic annotations, brain quantitative trait loci, and results from rare variant exome sequencing in BD. Convergent lines of evidence supported the roles of SCN2A, TRANK1, DCLK3, INSYN2B, SYNE1, THSD7A, CACNA1B, TUBBP5, PLCB3, PRDX5, KCNK4, AP001453.3, TRPT1, FKBP2, DNAJC4, RASGRP1, FURIN, FES, YWHAE, DPH1, GSDMB, MED24, THRA, EEF1A2, and KCNQ2 in BD. These represent promising candidates for functional experiments to understand biological mechanisms and therapeutic potential. Additionally, we demonstrated that fine-mapping effect sizes can improve performance and transferability of BD polygenic risk scores across ancestrally diverse populations, and present a high-throughput fine-mapping pipeline (https://github.com/mkoromina/SAFFARI).

Dorothea Gotfurt, 1907–1995
(2024)
Dorothea Gotfurt kam 1935 als Exilantin nach England. Dort wurde sie zur Übersetzerin. Zwischen 1955 und 1970 veröffentlichte sie vor allem im Scherz-Verlag (Bern), aber auch bei Fischer (Frankfurt/M.), Rowohlt (Reinbek) oder Szolnay (Wien) über dreißig von ihr ins Deutsche gebrachte Romane aus der zeitgenössischen englischsprachigen Literatur.
Die Bibliographie nennt alle in der Deutschen Nationalbibliothek vorhandenen Bücher Grete Fischers. Die Titel wurden mit Ausnahme der drei 1945/46 in Glasgow erschienenen Bücher autoptisch überprüft. Als Verlagslektorin hat sie durch mehrere Jahrzehnte an deutschen und englischen Übersetzungen mitgewirkt, die sich bisher jedoch bibliographisch nicht nachweisen ließen.
Auf Initiative des Schwerpunktes Ökotoxikologie im Masterstudiengang Umweltwissenschaften an der Justus-Liebig-Universität Gießen wurde eine neue Plattform für die Begegnung und Vernetzung der Studierenden untereinander eingerichtet, der sich nun zum ersten Mal jährt. Um mehr Einblicke in das praktische Versuchswesen und Studienangebote anderer Hochschulen zu geben, organisiert der Schwerpunkt Angebotsformate, die über die Vorlesungen hinausgehen. Der »Mittelhessische Tag der Ökotoxikologie« bringt Studierende der Technischen Hochschule Mittelhessen, der Goethe-Universität Frankfurt, der Philipps-Universität Marburg, jüngst auch der Universität Kassel und der JLU am FNU in Homberg (Ohm) zusammen und erlaubt ihnen Einblicke in die ökotoxikologische Forschung und Praxis.

Kinder und Jugendliche beschäftigen sich gerne mit audiovisuellen, auditiven und interaktiven Medien. Das Buch gerät im Mediengeflecht zunehmend in den Hintergrund. Um für die junge Zielgruppe attraktiv zu sein, setzen Verlage auf Bücher, die Themen, Geschichten und Darstellungsweisen aus anderen Medien aufgreifen. Dazu gehören auch die sogenannten Medienbegleitbücher, die in Bezug zu einem Film, einer Serie, einem Hörspiel oder einem digitalen Spiel stehen. Diese Bücher ermöglichen Kindern aufgrund der bereits bekannten Geschichten, Charaktere und Dialoge einen erleichterten Zugang zu Literatur und locken mit besonderen Gratifikationen, die vorlagenfreie Bücher nicht zu bieten haben. Daher sind sie als Lesestoffe auch für die Leseförderung interessant.
Diese Arbeit untersucht daher, welche Stellung Medienbegleitbücher im Kinder- und Jugendbuchmarkt sowie in der Leseförderung haben. Im ersten Teil liegt der Fokus auf der Produktion und Distribution von Begleitbüchern. Mithilfe einer Recherche im Katalog der Deutschen Nationalbibliothek wurden das Marktangebot erarbeitet und Rückschlüsse auf die Entwicklung des Genres gezogen. Jahresbestsellerlisten des Buchreport geben einen Eindruck vom Verkauf der Bücher. Forschungsliteratur zum Thema Lizenzen und Kommunikationspolitik in Verlagen ergänzt den Marktüberblick durch die Perspektive von Handel und Herstellung.
Im folgenden Kapitel werden unter Zuhilfenahme von Forschungsliteratur und Studien die Potenziale der Begleitbücher geschildert. Rezensionen und Bewertungen zu Medienbegleitbüchern auf LovelyBooks und Amazon geben Aufschluss über die Einstellung der Leser*innen und Beiträge in Zeitschriften der Kinder- und Jugendliteratur zeigen die Meinung der Vermittler*innen zu Begleitbüchern.
Der letzte Abschnitt der Arbeit beschäftigt sich mit dem Einsatz der Medienbegleitbücher in der Leseförderung. Stellvertretend für Angebote in der Familie und in Kindertagesstätten wurde die Arbeit der Stiftung Lesen Mainz betrachtet. Eine Analyse der Angebote und ein Experten-Interview geben nähere Einblicke in die Einbindung von Medienbegleitbüchern. Die Didaktik-Forschung gibt Auskunft über die Integration von Medienbegleitbüchern und Medienverbünden in den Unterricht. Im Bereich der außerschulischen Leseförderung wurde der Einsatz von Medienbegleitbüchern in den Lesestunden von Mentor e.V. Mainz mit einer Online-Umfrage unter den Mentor*innen untersucht. Der Katalog der Anna Seghers Bücherei Mainz zeigt das Angebot an Medienbegleitbüchern in Büchereien auf. Der Instagram-Account der Bücherei lässt Rückschlüsse über den Einsatz von Begleitbüchern in Aktionen zu.
Zusammenfassend konnte festgehalten werden, dass Medienbegleitbücher ein wichtiges Segment des Kinder- und Jugendbuchmarktes darstellen, hohe Umsätze generieren können und für den Handel von Bedeutung sind. Aufgrund des vielfältigen Angebots und der verschiedenen Vertriebswege können viele Zielgruppen angesprochen und erreicht sowie Barrieren zum Medium Buch abgebaut werden. Obwohl die Erfahrungen von Familienangehörigen und Mentor*innen belegen, dass sich Begleitbücher positiv auf die Lesemotivation und das Leseverhalten von Kindern und Jugendlichen auswirken können, werden sie in der Leseförderung bislang eher am Rande berücksichtigt. Sie werden zwar empfohlen, aber Konzepte für und Evaluationen von Projekten fehlen. Die Potenziale der Medienbegleitbücher und ihrer Medienverbünde werden daher nicht ausgeschöpft. Medienbegleitbücher sollten zunehmend in den Fokus gerückt und als Chance wahrgenommen werden, Heranwachsende für Bücher zu begeistern und ihre Lesefreude zu wecken.
Evidence of predation pressure on sensitive species by raccoons based on parasitological studies
(2024)
Highlights
• Parasitological analyses were carried out on 108 free-ranging raccoons in Germany.
• Three endoparasite species were newly discovered, alongside 13 parasites already known.
• A high prevalence of the pathogenic nematode Baylisascaris procyonis was identified.
• Uncovering endoparasites provides insights into predation events from the past.
• Stomach contents show serious negative impact of raccoons on native amphibians.
Abstract
To demonstrate predation and potential impacts of raccoons on various species, a total of 108 raccoons from aquatic-associated nature reserves and natural areas in three federal states of Germany, Hesse (n = 36), Saxony-Anhalt (n = 36) and Brandenburg (n = 36), were investigated from a dietary ecological perspective in the present study. Fecal analyses and stomach content examinations were conducted for this purpose. Additionally, as a supplementary method for analyzing the dietary spectrum of raccoons, the parasite fauna was considered, as metazoan parasites, in particular, can serve as indicators for the species and origin of food organisms. While stomach content analyses allow for a detailed recording of trophic relationships solely at the time of sampling, parasitological examinations enable inferences about more distant interaction processes. With their different developmental stages and heteroxenous life cycles involving specific, sometimes obligate, intermediate hosts, they utilize the food web to reach their definitive host. The results of this study clearly demonstrate that spawning areas of amphibians and reptiles were predominantly utilized as food resources by raccoons in the study areas. Thus, common toad (Bufo bufo), common newt (Lissotriton vulgaris), grass frog (Rana temporaria), and grass snake (Natrix natrix) were identified as food organisms for raccoons. The detection of the parasite species Euryhelmis squamula, Isthmiophora melis, and Physocephalus sexalatus with partially high infestation rates also suggests that both amphibians and reptiles belong to the established dietary components of raccoons from an ecological perspective, as amphibians and reptiles are obligate intermediate hosts in the respective parasitic life cycles of the detected parasites. The study clearly demonstrates that raccoons have a significant impact on occurrence-sensitive animal species in certain areas and, as an invasive species, can exert a negative influence on native species and ecosystems.
L'obiettivo del presente articolo è quello di offrire una visione complementare a quella abituale del romanzo "Die Entdeckung der Currywurst" di Uwe Timm in cui vengano privilegiati gli aspetti del romanzo che lo identificano come opera di World Literature. Se fino ad ora il romanzo è stato principalmente letto come un romanzo tedesco di guerra, con questa lettura si intende far emergere gli aspetti che di esso oltrepassano i confini nazionali e linguistici. Per fare questo si osserveranno in breve i punti di contatto fra la WL e la letteratura postcoloniale, dalla quale la WL stessa ha origine. In particolare si concentrerà l'attenzione sugli elementi del romanzo che evidenziano il rapporto con le letterature e culture di oltre confine, come la cornice narrativa, in cui la narrazione principale si iscrive; le contaminazioni letterarie che emergono dal racconto e infine i numerosi esempi di relazione fra centro e periferia. Inoltre, verrà evidenziato come il periodo storico in cui il romanzo è ambientato, ovvero quello della 'Stunde Null', abbia esso stesso dei contatti intrinseci con le teorie postcoloniali. Si mostrerà come la tesi dell'afferenza del presente romanzo alla WL, sia sostenuta dal fatto che anche attraverso romanzi precedenti, Uwe Timm mostra un interesse spiccato nei confronti delle realtà degli altri paesi e continenti e dell’eredità coloniale dell'Europa.
Arbeit und Spiel fungieren im allgemeinen Sprachgebrauch als Gegensätze. Spielen wird im Kontext dieser Oppositionsbeziehung als autotelische Handlung, also als eine freiwillige Beschäftigung mit unproduktivem Charakter, definiert, die primär der Freude oder Entspannung dient. Arbeiten hingegen wird als zweckorientierte Tätigkeit gefasst, die mit Ernsthaftigkeit und Mühsal assoziiert wird. In einer sich verändernden Arbeitswelt lösen sich diese binären Zuordnungen, sofern sie in dieser Schärfe überhaupt jemals bestanden haben, jedoch zunehmend auf. Arbeit und Spiel verschränken sich, sie bilden Hybridformen aus, bei denen sich Verschiebungen von Spielenden zu Arbeitenden und umgekehrt beobachten lassen. Die Etablierung der Spieleindustrie als Wirtschaftsbranche oder die Professionalisierung des Wettkampfsports bringen beispielsweise Formen des Play-as-Work hervor: "Sämtliche Tätigkeiten mit einer unterstellten Wirkabsicht können demnach als Arbeit begriffen werden. Daher können auch aus traditionellen Gründen oder aus Unterhaltungs- und Zerstreuungsgründen ausgeführte Tätigkeiten nunmehr als Arbeit verstanden werden, wenn ihnen eine Wirkabsicht unterstellt werden kann." Zudem werden in Arbeitsbereichen der postfordistischen Wissensökonomie ludische Elemente wie Kreativität, Improvisation oder Risikobereitschaft in einer Abwendung von der normierten Rationalisierung von Arbeit des Taylorismus aufgewertet und spielhaftes Arbeiten ohne kodifizierte Regeln (wieder) als Mittel wirtschaftlicher Produktivität erkannt. Seit den 1990er Jahren lassen sich ferner Tendenzen einer zunehmenden Entgrenzung und Subjektivierung von Erwerbstätigkeit ausmachen; hierbei wird die mit der Industrialisierung entstandene Trennung von Arbeit und Leben abgeschwächt und das Konzept Arbeit neu definiert, denn diese wird nun nicht mehr vornehmlich negativ als Plage oder göttliche Strafe gerahmt, sondern positiv als Mittel der Selbstverwirklichung konnotiert. Arbeit soll infolgedessen spielend von der Hand gehen und Vergnügen bereiten. Auf diese Weise wird eine work-as-play-Mentalität erzeugt, die die Differenz von Ernst und Spiel in der Betrachtungsweise der Handlung festmacht: Es hängt vom Ausführenden ab, ob eine Tätigkeit als Spiel oder als Arbeit klassifiziert wird. So kann letztlich jede Aktivität einfach zum Spiel erklärt werden. [...] Im Fokus dieses Artikels soll jedoch eine andere Form der Hybridisierung von Arbeit und Spiel stehen: die Repräsentation von Büroarbeit im Computerspiel. [...] Untersucht werden soll im Folgenden, welche Inszenierungsstrategien und Spielmechaniken eingesetzt werden, um das Büro spielbar zu machen. Wie wird das Setting für das Gameplay funktionalisiert und wie werden Arbeitsprozesse ludifiziert? Zu welcher Form des Spiels lädt das Büro ein? Welche Aspekte des Büroalltags werden aufgegriffen und welche Erzählungen sowie Figuren werden mit dem Schauplatz verbunden? Des Weiteren soll analysiert werden, wie über die räumliche Ästhetik inhaltliche Aussagen über die kulturelle Bedeutung und gesellschaftliche Wahrnehmung des Büros transportiert werden.
Der Begriff der Verblendung, ein oft implizit immer wiederkehrendes Thema in der Literatur, Philosophie, und auch in der Religion, hat eine komplexe Bedeutungsebene, die es vielleicht wohl zu bewahren gilt, anstatt sie zu fixieren und damit die Lesemöglichkeiten, die er eröffnen kann, zu reduzieren. Das Wort, das Offenes (etwa eine Hingabe an einen Glauben, die auch eine Selbsttäuschung, ein Fehler sein kann, aber auch Mut bedeuten kann) und Verborgenes (eine mehr oder weniger bewusste Täuschung anderer) zugleich andeutet, entzieht sich durch diese doppelte Struktur von 'Oberfläche' und 'Hintergrund' in gewisser Weise, ohnehin einer festen BeDeutungsgebung. In besonderer Weise bleibt der Begriff mit dem als 'Verliebtheit' umschriebenen Zustand als einer ambivalenten un/wahren, irrational und affektiv besetzten, relationalen, inneren Vorstellung und äußeren Projektion des Selbst und eines Anderen verbunden. Der Begriff kann die Hingabe an eine (trügerische) Romantik oder eine (trügerische) Hingabe an eine Romantik meinen, der ein Selbst und ein Anderes in eine affektive Beziehung zueinander setzt, und so auch die Möglichkeit des Unheimlichen, das Hineinbrechen eines Trug(-Bild)-es kennzeichnen. Dies wiederum ist engstens mit Angst und Wut, den oft als destruktiv dargestellten Affekten und affektiv besetzten Effekten verbunden. Verblendung ist somit auch ein Begriff, der Vorstellungen von 'Rationalität' und (affektiv-besetzter) 'Irrationalität', von 'Richtigkeit' und 'Falschheit' beinhaltet.
This paper relies on an unedited and unpublished nineteenth century love correspondence of a heterosexual couple from the German speaking area. The aim of this study is to contribute to the knowledge regarding the nineteenth century love experience of ordinary and unknown lovers. In fact, while there are plenty of books on love correspondences of famous personalities, little research has been dedicated to love letters and romantic experiences of 'ordinary and unknown' people. For this reason the main aim of this article is to shed light on love stories and love experiences that otherwise will fall into the abyss of oblivion. A new theory regarding the love experience in the nineteenth will be proposed: in this century love was perceived more in its material than in its abstract nature; I argue that in the nineteenth love was more about what people did, than to what they said. Lovers are in constant need of material and 'seeable' proof in order to perceive the love of their partners as real and authentic. The examples extrapolated from the following correspondence will corroborate this statement. Furthermore, this article has the purpose to underline the great value of love letters not only from an historical perspective (being evidence of past lives and dynamics), but also and more importantly from a cultural and societal one: analyzing love letters means to acquire knowledge not only about cultural and societal dynamics, but also and more importantly to add knowledge to the love discourse. In fact, they say a lot about the way people talked, expressed and materialized love in their daily lives. Correspondences without any publication in view are the most precious ones because they represent an unregulated and more spontaneous expression 'of the language of the heart'.
E.T.A. Hoffmanns Erzählung "Der Sandmann" ist dank Freuds Interpretation zu einem seiner wichtigsten Werke geworden. Die Novelle, die die Leser mit dem jungen Studenten Nathanael, der mit sich ein Kindheitstrauma trägt, bekannt macht, ist ein komplexes Werk, das auch den weltbekannten Mediziner fasziniert hat. Diese Arbeit befasst sich mit der schon erwähnten Novelle, mit Freuds Artikel "Das Unheimliche" und mit der sehr relevanten Verfilmung aus dem Jahr 2012. Das Motiv des Unheimlichen kommt in dieser Arbeit als eine Kontaktstelle vor, die auf drei verschiedenen Ebenen interpretiert wird: aus der Perspektive des Unheimlichen in der Novelle, aus Sigmund Freuds Perspektive und wie es im Film auftaucht. Ziel dieser Arbeit ist es zu beweisen, dass das Motiv des Unheimlichen in der Verfilmung anders als im Buch begriffen werden kann, d.h. dass Freuds Motiv des Unheimlichen im Text als gruseliger und verwirrender empfunden werden kann.
Der interdisziplinäre Sammelband eröffnet neue Perspektiven auf den Stil als bislang unterkonturierte literaturwissenschaftliche Leitkategorie unter transnationalen, wissens-, gattungs- und sprachgeschichtlichen Gesichtspunkten. Im 18. Jahrhundert zeichnet sich im Nachdenken über Schreibarten eine Neujustierung der Stilkategorie ab, die den Stil zur Reflexionsgröße für ästhetische Diskurse macht. Der Band sondiert die Pluralisierung, Historisierung und Individualisierung der Stilkategorie, die ihr neue literatur- und kulturtheoretische Anwendungsbereiche eröffnet. Die Bewegungen zwischen den Sprachen, Literaturen, Medien und semantischen Feldern erschließt die Publikation, indem sie europäische Vergleichshorizonte eröffnet und literatur- ebenso wie sprachwissenschaftliche Ansätze präsentiert. Damit leistet sie einen Beitrag zum Feld der komparatistisch ausgerichteten Germanistik, insbesondere der Literatur- und Kulturgeschichte des 18. Jahrhunderts und des europäischen Kulturtransfers.
Beyond well-established difficulties with working memory in individuals with attention deficit hyperactivity disorder (ADHD), evidence is emerging that other memory processes may also be affected. We investigated, first, which memory processes show differences in adults and adolescents with ADHD in comparison to control participants, focusing on working and short-term memory, initial learning, interference, delayed and recognition memory. Second, we investigated whether ADHD severity, co-occurring depressive symptoms, IQ and physical fitness are associated with the memory performance in the individuals with ADHD.
We assessed 205 participants with ADHD (mean age 25.8 years, SD 7.99) and 50 control participants (mean age 21.1 years, SD 5.07) on cognitive tasks including the digit span forward (DSF) and backward (DSB), the Rey Auditory Verbal Learning Test (RAVLT), and the vocabulary and matrix reasoning subtests of the Wechsler Abbreviated Scale of Intelligence. Participants with ADHD were additionally assessed on ADHD severity, depression symptoms and cardiorespiratory fitness. A series of regressions were run, with sensitivity analyses performed when variables were skewed.
ADHD-control comparisons were significant for DSF, DSB, delayed and recognition memory, with people with ADHD performing less well than the control participants. The result for recognition memory was no longer significant in sensitivity analysis. Memory performance was not associated with greater ADHD or depression symptoms severity. IQ was positively associated with all memory variables except DSF. Cardiorespiratory fitness was negatively associated with the majority of RAVLT variables.
Individuals with ADHD showed difficulties with working memory, short-term memory and delayed memory, as well as a potential difficulty with recognition memory, despite preserved initial learning.
Targeted protein degradation (TPD) has recently emerged as an exciting new drug modality. However, the strategy of developing small molecule-based protein degraders has evolved over the past two decades and has now established molecular tags that are already in clinical use, as well as chimeric molecules, PROteolysis TArgeting Chimeras (PROTACs), based mainly on ligand systems developed for the two E3 ligases CRBN and VHL. The large size of the human E3 ligase family suggests that PROTACs can be developed by targeting a large diversity of E3 ligases, some of which have restricted expression patterns with the potential to design disease- or tissue-specific degraders. Indeed, many new E3 ligands have been published recently, confirming the druggability of E3 ligases. This review summarises recent data on E3 ligases and highlights the challenges in developing these molecules into efficient PROTACs rivalling the established degrader systems.
Isothermal titration calorimetry (ITC) is a widely used technique for the characterization of protein-protein and protein-ligand interactions. It provides information on the stoichiometry, affinity, and the thermodynamic driving forces of interactions. This chapter exemplifies the use of ITC to investigate interactions between human autophagy modifiers (LC3/GABARAP proteins) and their interaction partners, the LIR motif containing sequences. The purpose of this report is to present a detailed protocol for the production of LC3/GABARAP-interacting LIR peptides using E. coli expression systems. In addition, we outline the design of ITC experiments using the LC3/GABARAP:peptide interactions as an example. Comprehensive troubleshooting notes are provided to facilitate the adaptation of these protocols to different ligand-receptor systems. The methodology outlined for studying protein-ligand interactions will help to avoid common errors and misinterpretations of experimental results.
This paper studies whether Eurosystem collateral eligibility played a role in the portfolio choices of euro area asset managers during the “dash-for-cash” episode of 2020. We find that asset managers reduced their allocation to ECB-eligible corporate bonds, selling them in order to finance redemptions, while simultaneously increasing their cash holdings. These findings add nuance to previous studies of liquidity strains and price dislocations in the corporate bond market during the onset of the Covid-19 pandemic, indicating a greater willingness of dealers to increase their inventories of corporate bonds pledgeable with the ECB. Analysing the price impact of these portfolio choices, we also find evidence pointing to price pressure for both ECB-eligible and ineligible corporate bonds. Bonds that were held to a larger extent by investment funds in our sample experienced higher price pressure, although the impact was lower for ECB-eligible bonds. We also discuss broader implications for the related policy debate about how central banks could mitigate similar types of liquidity shocks.
What are the aggregate and distributional consequences of the relationship be-tween an individual’s social network and financial decisions? Motivated by several well-documented facts about the influence of social connections on financial decisions, we build and calibrate a model of stock market participation with a social network that emphasizes the interplay between connectivity and network structure. Since connections to informed agents help spread information, there is a pivotal role for factors that determine sorting among agents. An increase in the average number of connections raises the average participation rate, mostly due to richer agents. A higher degree of sorting benefits richer agents by creating clusters where information spreads more efficiently. We show empirical evidence consistent with the importance of connectivity and sorting. We discuss several new avenues for future research into the aggregate impact of peer effects in finance.
Die Lincoln-Siedlung in der Wissenschaftsstadt Darmstadt ist sowohl bundesweites Modellprojekt in Sachen nachhaltiger Mobilität als auch Gegenstand verschiedener Forschungsprojekte. Im Projekt NaMoLi II wird die Zufriedenheit der Bewohnenden in der Lincoln-Siedlung mit dem Mobilitätskonzept und seiner Umsetzung analysiert. Des Weiteren wird geprüft, ob und in welcher Form die vorhandenen Rahmenbedingungen eine nachhaltige Mobilität fördern und wie sich die im Quartier bzw. im Umfeld vorhandenen Angebote der Versorgung und sozialen Infrastruktur auf das Mobilitätsverhalten insbesondere neu Zugezogener auswirken. Hierzu hat eine ausgewählte Bevölkerungsgruppe aus der Lincoln-Siedlung über einen Zeitraum von einer Woche Tagebuchprotokolle ihrer täglichen Mobilität geführt. Teilgenommen haben 14 Haushalte mit insgesamt 28 Personen, die zum Zeitpunkt der Erhebung maximal 15 Monate im Quartier gelebt haben. Die Protokolle wurden von allen Haushaltsangehörigen ab dem Grundschulalter geführt, jüngere Kinder sind in den Tagebüchern der Eltern erfasst. Notiert wurden Wegezwecke und Wegeziele, das genutzte Verkehrsmittel, Start- und Ankunftszeit sowie die (geschätzte) Entfernung. Des Weiteren wurden Kennwerte zur Haushaltsstruktur erhoben, zu geänderten Gewohnheiten nach dem Umzug in die Lincoln-Siedlung sowie nach Problemen in der Alltagsmobilität gefragt. Die Ergebnisse der Mobilitätstagebücher bieten einen interessanten Einblick in den Mobilitätsalltag einer spezifischen Teilnahmegruppe, die ein besonderes Interesse an Mobilitätsthemen gezeigt hat und die sich weitgehend nachhaltig in ihrem Alltag bewegt. Das Fahrrad ist das wichtigste Verkehrsmittel, gefolgt von den eigenen Füßen. Die Mehrzahl der Wegeziele liegt innerhalb eines Radius von bis zu zwei Kilometer. Die multimodalen Angebote im Quartier werden gut genutzt. Es hat sich gezeigt, dass die Methode der Tagebuchprotokolle über einen längeren Zeitraum zielführend ist, um Hinweise für die Alltagstauglichkeit des Mobilitätskonzeptes sowie zu dessen Weiterentwicklung bzw. Nachsteuerung zu erlangen.
This study analyses potential consequences of exiting the Targeted Long-Term Refinancing Operations (TLTRO) of the European Central Bank (ECB). Thanks to its asset purchase programs, the Eurosystem still holds plenty of reserves even with a full exit from the TLTROs. This explains why voluntary and mandatory repayments of TLTRO III borrowing went smoothly. Nevertheless, the more liquidity is drained from the banking system, the more important becomes interbank market borrowing and lending, ideally between euro area member states. Right now, the usual fault lines of the euro area show up. The German banking system has plenty of reserves while there are first signs of aggregate scarcity in the Italian banking system. This does not need to be a source of concern if the interbank market can be sufficiently reactivated. Moreover, the ECB has several tools to address possible future liquidity shortages.

Das Ziel der BMBF-finanzierten Forschungsprojekte „Nachhaltige Mobilität in Lincoln 1“ und „Nachhaltige Mobilität in Lincoln 2“ ist es, Erkenntnisse zu Veränderungen im Mobilitätsverhalten von Personen zu erlangen, die in ein autoreduziertes Quartier umziehen. Dazu wurden zwei aufeinander aufbauende Vollbefragungen der erwachsenen Bewohner*innen der autoreduzierten Lincoln-Siedlung in Darmstadt durchgeführt. Im Rahmen der ersten Befragung im Jahr 2020 wurden 1.140, im Rahmen der zweiten Befragungswelle, 2021, 1.614 Fragebögen verteilt. Der Rücklauf belief sich 2020 auf n = 166 (14,6 %), in 2021 auf n = 231 (14,3 %). Der vorliegende Bericht beschreibt das methodische Vorgehen im Rahmen der Befragungen. Hierfür wird auf das besondere Panel-Design der Studie eingegangen. Dieses ermöglicht sowohl Einblicke in den Umzug in die Siedlung, als auch in das Leben in der Siedlung im Verlauf eines Jahres, und die damit einhergehenden Veränderungen im individuelle Mobilitätsverhalten. Der Bericht stellt dazu die zentralen Inhalte des Fragebogens vor und erläutert die Durchführung der Befragungen. In deren Rahmen wurden die Bewohner*innen der Lincoln-Siedlung insgesamt dreimal kontaktiert. Um die Bereitschaft zur Teilnahme zu steigern, wurden im Vorfeld der Erhebungen mittels einer Pressemitteilung auf die Befragung aufmerksam gemacht und Ankündigungsschreiben in die Briefkästen der Bewohner*innen verteilt. Eine Woche nach der eigentlichen Fragebogenverteilung wurden Erinnerungsschreiben verteilt. Ferner geht der Methodenbericht auf den Umgang mit dem Rücklauf sowie auf die Datenaufbereitung und - eingabe ein, bevor die soziodemographischen Daten der Teilnehmer*innen auf ihre Repräsentativität geprüft werden.
Almost ten years after the European Commission action plan on building a capital markets union (CMU) and despite incremental progress, e.g. in the form of the EU Listing Act, the picture looks dire. Stock exchanges, securities markets, and supervisory authorities remain largely national, and, in many cases, European companies have decided to exclusively list overseas. Notwithstanding the economic and financial benefits of market integration, CMU has become a geopolitical necessity. A unified capital market can bolster resilience, strategic autonomy, and economic sovereignty, reduce dependence on external funding, and may foster economic cooperation between member states.
The reason for the persistent stand-still in Europe’s CMU development is not so much the conflict between market- and state-based integration, but rather the hesitancy of national regulatory and supervisory bodies to relinquish powers. If EU member states wanted to get real about CMU (as they say, and as they should), they need to openly accept the loss of sovereignty that follows from a true unified capital market. Building on economic as well as historical evidence, the paper offers viable proposals on how to design competent institutions within the current European framework.
This note outlines the case for speedy capital market integration and for the adoption of a common regulatory framework and single supervisory authority from a political economy perspective. We also show the alternative case for harmonization and centralization via regulatory competition, elaborating how competition between EU jurisdictions by way of full mutual recognition may lead to a (cost-)efficient and standardized legal framework for capital markets. Lastly, the note addresses the political economy conflict that underpins the implementation of both models for integrating capital markets. We point out that, in both cases, national authorities experience a loss of legislative and jurisdictional competence at the national level. We predict that any plan to foster a stronger capital market union, following an institution based or a market-based strategy, will face opposition from powerful national stakeholders.
Experiments are an important tool in economic research. However, it is unclear to which extent the control of experiments extends to the perceptions subjects form of such experimental decision situations. This paper is the first to explicitly elicit perceptions of the dictator and trust game and shows that there is substantial heterogeneity in how subjects perceive the same game. Moreover, game perceptions depend not only on the game itself but also on the order of games (i.e., the broader experimental context in which the game is embedded) and the subject herself. This highlights that the control of experiments does not necessarily extend to game perceptions. The paper also demonstrates that perceptions are correlated with game behavior and moderate the relationship between game behavior and field behavior, thereby underscoring the importance and relevance of game perceptions for economic research.
The economic rise of China has changed the global economy. The authors explore China’s transformation from a low-cost manufacturing hub to an increasingly innovation- and service-driven economy. Major growth drivers for the period 2010-2025 are analysed, including the paradigms of “Made in China” and the “Dual Circulation Strategy”. The export intensity of China’s economy is declining overall, with a tendency towards greater regional diversification and a gradual decoupling from North America and the European Union. At the same time, trade and investment activities are increasingly geared to the Belt and Road Initiative. Furthermore, labour and energy cost advantages for manufacturing operations in China are likely to diminish in the coming years, calling into question China’s attractiveness as a global manufacturing hub. In this regard, the further development of regional and industrial clusters is pivotal for China to enhance its global competitiveness and remain an attractive destination for foreign direct investment (FDI) in the medium term. On the other hand, high productivity in science and technology and rich deposits of critical minerals put China in a favourable position in advanced industries. Important challenges include the still wide development gap between rural and urban areas, the structural mismatch in the labour market, with persistently high youth unemployment, and the race to achieve carbon neutrality by 2060.
Highlights
• Family structure transitions decrease academic school track attendance among children of less educated parents.
• Children of highly educated fathers in single-mother families also have lower outcomes.
• Reduced income and increased exposure to poverty are relevant mediators.
• There is no cumulative disadvantage linked to a further transition to a stepfamily.
• Previous parental separation does not affect educational outcomes for children residing with a highly educated stepfather.
Abstract
Recent research has documented that the effect of parental separation on children’s educational outcomes depends on socioeconomic background. Yet, parental separation could lead to a stable single-parent family or to a further transition to a stepfamily. Little is known about how the effect of family structure transitions on educational outcomes depends on the education of parents and stepparents, and there has been limited empirical research into the mechanisms that explain heterogeneity in the effects of family transitions. Using longitudinal data from the German Socio-Economic Panel and models with entropy balancing and sibling fixed effects, I explore the heterogeneous effects of family transitions during early and middle childhood on academic secondary school track attendance, grades and aspirations. I find that family transitions only reduce the academic school track attendance among children of less educated parents living in stepfamilies or with a single mother after parental separation, and among children of highly educated fathers living in single-mother families. The mechanisms that partly explain these effects relate to reduced income and exposure to poverty after parental separation. The findings underscore the importance of considering the stepparent's educational level, indicating that the adverse consequences of parental separation on educational outcomes are mitigated when a highly educated stepfather becomes part of the family. Overall, these findings align more closely with the resource perspective than the family stability perspective.

• Pre-service teachershave stereotypes towards pupils with autism, Down syndrome and dyslexia.
• Pupils with Down syndrome, autism and dyslexia are associated with distinctive stereotypes.
• These stereotypes can be classified in three resp. four different dimensions.
Abstract
Stereotypes about pupils with special educational needs are prevalent both in society and among pre- and in-service teachers. However, little is known about the specific stereotypes pre-service teachers associate with autistic pupils, pupils with Down syndrome, and pupils with dyslexia. We explored these in two studies. Study 1 (N=13) involved qualitative interviews to identify potential stereotype content. Study 2 (N=213) used these findings to create a questionnaire to quantify these stereotypes. We found distinct stereotypes associated with all three groups of pupils. For successful inclusion, teachers must recognize the uniqueness of each pupil, including those with different diagnoses.
Homocopris Burmeister, 1846 (Coleoptera: Scarabaeidae) is a small genus of South American dung beetles composed of four species distributed in Argentina, Brazil, and Chile. Recently, a neotype was designated for Copris torulosus Eschscholtz, 1822 (currently H. torulosus) based on the assumption that the original type series had been lost. However, this designation is invalid for failing to comply with articles 75.2, 75.3, 75.3.1, and 75.3.4. of the International Code of Zoological Nomenclature. Furthermore, even if it had been nomenclaturally valid, the neotype now loses its type status because we found a syntype in the material of the Johann Friedrich Eschscholtz collection, preserved in the collection of Zoological Museum, Moscow Lomonosov State University, Moscow, Russia. We present evidence supporting the recognition of this specimen as a syntype and newly designate it as the lectotype. Photographs of the lectotype and its labels are provided. Additionally, the geographic distributions of H. punctatissimus (Curtis, 1844) and H. torulosus (Eschscholtz, 1822) in Chile are corrected.

Three Nearctic species of Episyron Schiødte (Hymenoptera: Pompilidae: Pompilinae: Pompilini) were examined morphologically, geographically, and ecologically with intent to infer an aposematic correlation with habitat type, protarsal digging rake morphology, and host spider association. Episyron quinquenotatus quinquenotatus (Say) and E. conterminus cressoni (Dewitz), two subspecies with extensive aposematic markings and more and longer protarsal comb spines, were associated with bare or sparsely vegetated sandy soils near water courses. Episyron biguttatus biguttatus (Fabricus), with few aposematic markings and less and shorter protarsal comb spines, was associated with more densely vegetated terrain and gravelly and loamy soils. Three subspecies of Anoplius apiculatus (Smith) (Hymenoptera: Pompilidae: Pompilinae: Pompilini) are discussed as an aposematic-habitat comparison.

Research around the “glass escalator” demonstrates that men receive promotions faster than women in women-dominated occupations. However, it remains unclear how overall establishment composition affects the glass escalator. We use German longitudinal linked employer-employee data (LIAB) between 2012 and 2019 to examine how occupational and establishment gender composition shape gender differences in promotions to management. Establishment gender composition moderates the glass escalator, meaning women's mobility disadvantages in women-dominated jobs are most pronounced in men-dominated establishments. We hypothesize that changing occupational status is a central mechanism: When occupations mirror the composition of the establishment, their status increases locally. Higher occupational status offsets lower leadership expectations attributed to women and increases women's promotion odds relative to their male colleagues.
PET probes targeting fibroblasts are frequently used for varying applications in oncology. In recent years, the clinical spectrum has been expanded towards cardiovascular medicine, e.g., after myocardial infarction, in aortic stenosis or as a non-invasive read-out of atherosclerosis. We herein provide a brief overview of the current status of this PET radiotracer in the context of cardiovascular disease, including translational and clinical evidence. In addition, we will also briefly discuss future applications, e.g., the use of fibroblast-targeting PET to investigate bilateral organ function along the cardiorenal axis.

The genera Lophalia Casey, 1912, Mannophorus LeConte, 1854 and Ischnocnemis Thomas, 1864 (Coleoptera: Cerambycidae: Cerambycinae: Trachyderini) are recharacterized by providing additional morphological features to enhance the delineation of these genera. Two species Lophalia cribricollis Bates, 1892 and Ischnocnemis luteicollis (Bates, 1885) are transferred to a new genus Lophaliamorpha Eya with Lophaliamorpha luteicollis (Bates) new combination as the type species. Ischnocnemis skillmani Chemsak and Hovore, 2010 is transferred to a new genus Paramannophorus Eya with Paramannophorus skillmani (Chemsak and Hovore) new combination as the type species.

Interferon-stimulated gene-15 (ISG15) is an interferon-induced protein with two ubiquitin-like (Ubl) domains linked by a short peptide chain, and the conjugated protein of the ISGylation system. Similar to ubiquitin and other Ubls, ISG15 is ligated to its target proteins with a series of E1, E2, and E3 enzymes known as Uba7, Ube2L6/UbcH8, and HERC5, respectively. Ube2L6/UbcH8 plays a literal central role in ISGylation, underscoring it as an important drug target for boosting innate antiviral immunity. Depending on the type of conjugated protein and the ultimate target protein, E2 enzymes have been shown to function as monomers, dimers, or both. UbcH8 has been crystalized in both monomeric and dimeric forms, but the functional state is unclear. Here, we used a combined approach of small-angle X-ray scattering (SAXS) and nuclear magnetic resonance (NMR) spectroscopy to characterize UbcH8′s oligomeric state in solution. SAXS revealed a dimeric UbcH8 structure that could be dissociated when fused with an N-terminal glutathione S-transferase molecule. NMR spectroscopy validated the presence of a concentration-dependent monomer-dimer equilibrium and suggested a backside dimerization interface. Chemical shift perturbation and peak intensity analysis further suggest dimer-induced conformational dynamics at ISG15 and E3 interfaces - providing hypotheses for the protein′s functional mechanisms. Our study highlights the power of combining NMR and SAXS techniques in providing structural information about proteins in solution.

• Marburg virus infects and replicates in primary human proximal tubular cells (PTC).
• Transcriptome analyses at multiple time points revealed a profound inflammatory response by IFNα, -y and TNFα signaling.
• Among the strongly downregulated gene sets were targets of the transcription factors MYC and E2F, the G2M checkpoint, as well as oxidative phosphorylation.
• Importantly, the downregulated factors comprise PGC-1α, a key factor in mitochondrial biogenesis and renal energy homeostasis, to be substantially downregulated in MARV-infected PTC.
• Our results suggest inflammation-induced changes in tubular energy metabolism as a possible factor in MARV-associated tubular dysfunction.
Abstract
Marburg virus, a member of the Filoviridae, is the causative agent of Marburg virus disease (MVD), a hemorrhagic fever with a case fatality rate of up to 90 %. Acute kidney injury is common in MVD and is associated with increased mortality, but its pathogenesis in MVD remains poorly understood. Interestingly, autopsies show the presence of viral proteins in different parts of the nephron, particularly in proximal tubular cells (PTC). These findings suggest a potential role for the virus in the development of MVD-related kidney injury. To shed light on this effect, we infected primary human PTC with Lake Victoria Marburg virus and conducted transcriptomic analysis at multiple time points. Unexpectedly, infection did not induce marked cytopathic effects in primary tubular cells at 20 and 40 h post infection. However, gene expression analysis revealed robust renal viral replication and dysregulation of genes essential for different cellular functions. The gene sets mainly downregulated in PTC were associated with the targets of the transcription factors MYC and E2F, DNA repair, the G2M checkpoint, as well as oxidative phosphorylation. Importantly, the downregulated factors comprise PGC-1α, a well-known factor in acute and chronic kidney injury. By contrast, the most highly upregulated gene sets were those related to the inflammatory response and cholesterol homeostasis. In conclusion, Marburg virus infects and replicates in human primary PTC and induces downregulation of processes known to be relevant for acute kidney injury as well as a strong inflammatory response.
Background: Urachal cancer (UrC) is a rare disease with limited availability of representative incidence and clinical data. Although, the prevalence is accounting for less than 1% of bladder tumors, the 5-year survival rate is around only 50% for patients with resectable tumors, and even worse for patients with metastatic disease. Due to the lack of comprehensive prospective studies, our current knowledge of UrC is still limited.
Objective: The present study aimed to summarize the available registry-based studies with unselected UrC patients to evaluate its incidence and clinicopathological characteristics.
Material and methods: We conducted a systematic literature search of registry-based UrC publications on the 15th of May 2023 in 5 databases, which identified 4,748 publications. After duplicate removal and selection by 2 independent investigators, 6 publications proved to be appropriate for the final meta-analysis. Estimated incidence and clinicopathological parameters were extracted.
Results: Estimated incidence ranged between 0.022 and 0.060/ 100.000 person-years, with the highest occurrence in Japan and the lowest in Canada, while the random effect model calculated an overall incidence rate of 0.04 (95%CI: 0.03–0.05) 100.000 person-years. The median age at first diagnosis was 60 years (range: 58–64). The female to male ratio was 2:3. Lymph node or distant metastases were present in 9% and 14% of patients. The predominant tumour type was adenocarcinoma (86%) followed by urothelial carcinoma (12%) and squamous cell carcinoma (2%). The 5-year survival rate was 51.0% with 95%CI: 45.2–57.4.
Conclusions: Our study provides an up-to-date comparison of estimated incidence rates between 6 countries of 3 continents based on rigorously selected registry-based studies. The results suggest low incidence rates for UrC with considerable geographic differences. The present meta-analysis provides unbiased registry-based data on the incidence, clinicopathological parameters and survival of UrC.
Highlights
• Parents with and without migration background differ in educational knowledge.
• Parents with migration background have less educational knowledge on average.
• Variations in educational knowledge by immigrant groups.
• Social and cultural resources are central to explaining knowledge differences.
• Acculturation strategies prove to be of little relevance.
Abstract
Although extant research persistently highlights the importance of information for educational decision-making, better understanding the existence of, and the underlying reasons for, informational differences between immigrant and non-immigrant parents is important. This study examines the differences in the level of information between immigrant and non-immigrant parents of third graders just before they make probably their most important educational decision in the German education system. We draw on approaches highlighting the importance of resources and parents’ acculturation to explain the informational differences between immigrant and non-immigrant parents. Employing linear regression and probability models on data from the National Educational Panel Study in Germany (N = 3961), we demonstrate that all immigrant groups, particularly those from Turkey, the former Yugoslavia, the Middle East, and northern Africa, are significantly less informed than parents without own immigration experience. This result is evident both in our overall test and in various domains of the test, which analyze different aspects of information relevant to parents’ educational decision-making. Furthermore, different endowments with social and cultural capital largely explain the informational differences between parents with and without an immigrant background. In contrast, different acculturation strategies are almost negligible in explaining the differences in the level of information. Our findings provide important insights for research on migration-related inequalities in educational decision-making and for developing interventions to improve migrant parents’ ability to make well-informed and thus intended educational decisions.
Understanding the underlying mechanisms that link psychopathology and physical comorbidities in schizophrenia is crucial since decreased physical fitness and overweight pose major risk factors for cardio-vascular diseases and decrease the patients’ life expectancies. We hypothesize that altered reward anticipation plays an important role in this. We implemented the Monetary Incentive Delay task in a MR scanner and a fitness test battery to compare schizophrenia patients (SZ, n = 43) with sex- and age-matched healthy controls (HC, n = 36) as to reward processing and their physical fitness. We found differences in reward anticipation between SZs and HCs, whereby increased activity in HCs positively correlated with overall physical condition and negatively correlated with psychopathology. On the other handy, SZs revealed stronger activity in the posterior cingulate cortex and in cerebellar regions during reward anticipation, which could be linked to decreased overall physical fitness. These findings demonstrate that a dysregulated reward system is not only responsible for the symptomatology of schizophrenia, but might also be involved in physical comorbidities which could pave the way for future lifestyle therapy interventions.
From hunting and foraging to clearing land for agriculture, humans modify forest biodiversity, landscapes, and climate. Forests constantly undergo disturbance–recovery dynamics and understanding them is a major objective of ecologists and conservationists. Chronosequences are a useful tool for understanding global restoration efforts. They represent a space-for-time substitution approach suited for the quantification of the resistance of ecosystem properties to withstand disturbance and the resilience of these properties until reaching pre-disturbance levels. Here we introduce a newly established chronosequence with 62 plots (50 ⍰ 50 m) in active cacao plantations and pastures, early and late regeneration, and mature old-growth forests, across a 200 km2 area in the extremely wet Chocó rainforest. Our chronosequence covers by far the largest total area of plots compared to others in the Neotropics. Plots ranged from 159–615 masl in a forested landscape with 74 ± 2.8 % forest cover within a 1-km radius including substantial old-growth forest cover. Land-use legacy and regeneration time were not confounded by elevation. We tested how six forest structure variables (maximum tree height and DBH, basal area, number of stems, vertical vegetation heterogeneity, and light availability), aboveground biomass (AGB), and rarefied tree species richness change along our chronosequence. Forest structure variables, AGB, and tree species richness increased with regeneration time and are predicted to reach similar levels to those in old-growth forests after ca. 30–116, 202, and 108 yrs, respectively. Compared to previous work in the Neotropics, old-growth forests in Canandé accumulate high AGB that takes one of the largest time spans reported until total recovery. Our chronosequence comprises one of the largest tree species pools, covers the largest total area of regenerating and old-growth forests, and has higher forest cover than other Neotropical chronosequences. Hence, our chronosequence can be used to determine the time for recovery and stability (resistance and resilience) of different taxa and ecosystem functions, including species interaction networks. This integrative effort will ultimately help to understand how one of the most diverse forests on the planet recovers from large-scale disturbances.
We create an alternative version of the present utility value formula to explicitly show that every store-of-value in the economy bears utility-interest (non-pecuniary income) for ist holder regardless of possible interest earnings from financial markets. In addition, we generalize the well-known welfare measures of consumer and producer surplus as present value concepts and apply them not only for the production and usage of consumer goods and durables but also for money and other financial assets. This helps us, inter alia, to formalize the circumstances under which even a producer of legal tender might become insolvent. We also develop a new measure of seigniorage and demonstrate why the well-established concept of monetary seigniorage is flawed. Our framework also allows us to formulate the conditions for liability-issued money such as inside money and financial instruments such as debt certificates to become – somewhat paradoxically – net wealth of the society.
Highlights
• CD62p + exosomes were significantly increased in septic polytrauma-patients, while CD40+, as well as CD49e + exosomes were diminished.
• Exosomal IL-6 concentration in septic patients reflects the systemic IL-6.
• Exosomal IL-10 concentration seemed to be constant in patients and healthy controls.
• Decrease of miR-21 in exosomes was associated with the development of sepsis, while exosomal miR-93, miR-155 and miR-92a were not specifically altered.
Abstract
Sepsis as a severe systemic inflammation leads oftentimes to organ dysfunction and subsequently to death. In polytrauma patients, septic complications represent with 45% the predominant cause of late death and are responsible for extremely high costs in the healthcare system. Therefore, clinicians have to detect as early as possible the begin of sepsis to improve the patient's outcome. One new promising diagnostic tool to diagnose septic complications in polytraumatized patients are exosomes.
Plasma samples from polytraumatized patients (Injury Severity Score (ISS) ≥16) which developed sepsis (n = 10) and without sepsis (n = 10), were collected at emergency room (ER), 24h and 5 days after trauma. The EVs subpopulations were investigated by a bead-based multiplex flow cytometry measurement of surface epitopes and were compared with plasma EVs from healthy controls (n = 10). Moreover, exosomal cytokine concentrations were measured via high-sensitive ELISA and were correlated with systemic concentrations. For miRNA cargo analysis, we analysed the miRNAs miR-1298-5p, miR-1262, miR-125b-5p, miR-92a-3p, miR-93-5p, miR-155-5p and miR-21-5p and compared their exosomal concentrations by means of RT-qPCR.
CD62p + exosomes were significantly increased in septic polytrauma-patients (p ≤ 0.05), while CD40+exosomes, as well as CD49e + exosomes were diminished (p ≤ 0.05). Furthermore, we observed that the exosomal IL-6 concentration reflects the systemic IL-6 concentration (r2 = 0.63) and did not significantly alter between patients with and without sepsis. The exosomal IL-10 concentration seemed to be constant in all patients and healthy controls. We observed that a decrease of miR-21-5p in exosomes was associated with the development of sepsis (p ≤ 0.05), while exosomal miR-93-5p, miR-155-5p and miR-92a-3p were not specifically altered in septic patients.
Taken together, the present study in polytraumatized patients demonstrated that the development of sepsis is associated with an increase of CD62p + exosomes. Furthermore, the exosomal cargo was changed in septic patients: miR-21-5p was diminished.
