AB - We study the relationship between risk managers' dark triad personality traits (Machiavellianism, narcissism, and psychopathy) and their selective hedging activities. Using a primary survey of 412 professional risk managers, we find that managers with dark personality traits are more likely to engage in selective hedging than those without. This effect is particularly pronounced for older, male, and less experienced risk managers. The effect is also stronger in smaller firms, less centralized risk management departments, and family-owned firms.

AB - Abstract
For a compact Riemannian locally symmetric space $\mathcal M$ of rank 1 and an associated vector bundle $\mathbf V_{\tau }$ over the unit cosphere bundle $S^{\ast }\mathcal M$, we give a precise description of those classical (Pollicott–Ruelle) resonant states on $\mathbf V_{\tau }$ that vanish under covariant derivatives in the Anosov-unstable directions of the chaotic geodesic flow on $S^{\ast }\mathcal M$. In particular, we show that they are isomorphically mapped by natural pushforwards into generalized common eigenspaces of the algebra of invariant differential operators $D(G,\sigma )$ on compatible associated vector bundles $\mathbf W_{\sigma }$ over $\mathcal M$. As a consequence of this description, we obtain an exact band structure of the Pollicott–Ruelle spectrum. Further, under some mild assumptions on the representations $\tau$ and $\sigma$ defining the bundles $\mathbf V_{\tau }$ and $\mathbf W_{\sigma }$, we obtain a very explicit description of the generalized common eigenspaces. This allows us to relate classical Pollicott–Ruelle resonances to quantum eigenvalues of a Laplacian in a suitable Hilbert space of sections of $\mathbf W_{\sigma }$. Our methods of proof are based on representation theory and Lie theory.

AB - The theory of visual attention, “TVA”, is an influential and formal theory of attentional selection. It is widely applied in clinical assessment of attention and fundamental attention research. However, most TVA-based research is based on accuracy data from letter report experiments performed in controlled laboratory environments. While such basic approaches to questions regarding attentional selection are undoubtedly useful, recent technological advances have enabled the use of increasingly sophisticated experimental paradigms involving more realistic scenarios. Notably, these studies have in many cases resulted in different estimates of capacity limits than those found in studies using traditional TVA-based assessment. Here we review recent developments in TVA-based assessment of attention that goes beyond the use of letter report experiments and experiments performed in controlled laboratory environments. We show that TVA can be used with other tasks and new stimuli, that TVA-based parameter estimation can be embedded into complex scenarios, such as games that can be used to investigate particular problems regarding visual attention, and how TVA-based simulations of “visual foraging” can elucidate attentional control in more naturalistic tasks. We also discuss how these developments may inform future advances of TVA.

AB - The advantages of Additive Manufacturing (AM) highlight the capability to become an inherent part within the product development process. However, process specific challenges harm its further currency for industrial applications, for instance the high geometrical deviations. Different process factors influence the manufacturing accuracy and lead to large dimensional, form and positional deviations. Published research relative to deviations is difficult to compare, because it is based on several specimens that were manufactured with different processes, materials and machine settings. This fact emphasizes that reliable tolerance values for AM are hard to define in standards. Within this investigation, a universally applicable method was developed to examine geometrical deviations for AM processes. The main aim is the derivation of achievable tolerance values considering important influencing factors. Furthermore, due to the locally varying surface roughness of additively manufactured parts several tactile measurements were compared.

AB - AbstractUsing data from the German Socio-Economic Panel for 1984–2018, we analyze the intergenerational education mobility of immigrants in Germany by identifying the determinants of differences in educational stocks for first- and second-generation immigrants in comparison to individuals without a migration background. Our results show that on average, first-generation immigrants have fewer years of schooling than native-born Germans and have a disproportionate share of lower educational qualifications. This gap is strongly driven by age at immigration, with immigration age and education revealing a nonlinear relationship. While the gap is relatively small among individuals who migrate at a young age, integrating in the school system at secondary school age leads to large disadvantages. Examining the educational mobility of immigrants in Germany, we identify an inter-generational catch-up in education. The gap in education between immigrants and natives is reduced for the second generation. Finally, we find that country of origin differences can account for much of the education gap. While immigrants with an ethnic background closer to the German language and culture show the best education outcomes, immigrants from Turkey, Italy, and other southern European countries and especially the group of war refugees from Syria, Afghanistan, Iraq and other MENA countries, have the lowest educational attainment.

AB - AbstractUsing time series data for the period 1959–2015, our empirical analysis examines the simultaneous effects of the individual components of the global carbon budget on temperature. Specifically, we explore the possible effects of carbon emissions caused by fossil fuel combustion, cement production, land-use change emissions, and carbon sinks (here in terms of land sink and ocean sink) on climate change. The simultaneous inclusion of carbon emissions and carbon sinks allows us to look at the coexistent and opposing effects of the individual components of the carbon budget and thus provides a holistic perspective from which to explore the relationship between the global carbon budget and global warming. The results reveal a significant positive effect of carbon emissions on temperature for both fossil fuels emissions and emissions from land-use change, confirming previous results concerning carbon dioxide and temperature. Further, while ocean sink does not seem to have a significant effect, we identify a temperature-decreasing effect for land sink.

AB - With the rapid progress of technological development, self-efficacy in reference to digital devices (i.e., information and computer technology [ICT] self-efficacy) is an important driver that helps students to deal with technological problems and support their lifelong learning processes. Schools, peers, and home learning environments are important sources for the development of positive self-efficacy. Expanding on previous research, we investigated the associations between different aspects of the digital home learning environment and students’ ICT self-efficacy. The moderation effects of gender were also tested. A total of 651 children answered a questionnaire about different digital home learning environment dimensions and estimated their ICT self-efficacy using an adapted scale—Schwarzer and Jerusalem’s (1999) general self-efficacy scale. Using the structural equation modeling technique, a digital home learning environment containing six different qualities of parental support was investigated. Families’ cultural capital, parents’ attitudes toward the Internet, and shared Internet activities at home contributed positively to ICT self-efficacy. We observed small gender differences, with the moderation effect being nonsignificant. The results help researchers and practitioners to understand how different dimensions of the digital home learning environment support ICT self-efficacy. We will discuss how parents can enhance the home learning environment and how teachers can integrate this knowledge into formal education.

AB - Several methods are available to answer questions regarding similarity and accuracy,
each of which has specific properties and limitations. This study focuses on the
Latent Congruence Model (LCM; Cheung, 2009), because of its capacity to deal
with cross-informant measurement invariance issues. Until now, no cross-national
applications of LCM are present in the literature, perhaps because of the difficulty
to deal with both cross-national and cross-informant measurement issues implied by
those models. This study presents a step-by-step procedure to apply LCM to dyadic
cross-national research designs controlling for both cross-national and cross-informant
measurement invariance. An illustrative example on parent–child support exchanges in
Italy and Germany is provided. Findings help to show the different possible scenarios
of partial invariance, and a discussion related to how to deal with those scenarios is
provided. Future perspectives in the study of parent–child similarity and accuracy in
cross-national research will be discussed.

between relationship quality and subjective well-being. Mediation effects of
the relationship quality on the associations between value similarity and
subjective well-being were focused. The sample consisted of 600 adult
German children (53.8% women) and their parents. Dyadic correlations were
constructed to determine the value similarity. In this study, the general value
orientation and the family values were objects of research. We measured the
subjective well-being with the Satisfaction with Life Scale and we used the
Network of Relationships Inventory (NRI) to measure the relationship
quality. Associations between subjective well-being and value similarity, and
between subjective well-being and relationship quality, as well as mediation
effects, were found. All effects depend on gender and perspective.

AB - Die Querschnittsuntersuchung beschäftigt sich mit der Fragestellung, ob in Zusammenhang mit der familiären Lebenssituation Erwachsener (Elternstatus und Beziehungsstatus) Unterschiede hinsichtlich der Werteähnlichkeit zwischen ihnen und ihren Eltern bestehen. Dabei wurde die Ähnlichkeit der individuellen Grundwerte nach Schwartz (1992) fokussiert. Die Werteähnlichkeit wurde mittels dyadischer Korrelationen bestimmt (Kenny & Winquist, 2001). Die Stichprobe bestand aus N= 1047 Dyaden. Dafür nahmen 600 erwachsene Kinder (53.8 % weiblich) mit ihren Eltern (542 Mütter und 505 Väter) teil. Das Alter der teilnehmenden Kinder lag zwischen 25 und 49 Jahren (M= 33.9, SD = 6.1). Die Ergebnisse dieser Studie zeigten, dass sich die Werteähnlichkeiten in Abhängigkeit von der familiären Lebenssituation unterschieden: Die Elternschaft der erwachsenen Kinder ging mit einer größeren Werteähnlichkeit in der Mutter-Kind-Dyade einher. Ebenso konnte eine größere Werteähnlichkeit zwischen verheirateten Söhnen und deren beiden Elternteilen beobachtet werden, verglichen mit den Söhnen, die Single oder in einer Partnerschaft waren. Die Werteähnlichkeit der Töchter zu ihren Eltern unterschied sich nicht in Abhängigkeit des Beziehungsstatus.

AB - Genetic correlations suggest a coexisting genetic predisposition to both low leptin levels and risk for anorexia nervosa (AN). To investigate the causality and direction of these associations, we performed bidirectional two-sample Mendelian randomization (MR) analyses using data of the most recent genome-wide association study (GWAS) for AN and both a GWAS and an exome-wide-association-study (EWAS) for leptin levels. Most MR methods with genetic instruments from GWAS showed a causal effect of lower leptin levels on higher risk of AN (e.g. IVW b = −0.923, p = 1.5 × 10−4). Because most patients with AN are female, we additionally performed analyses using leptin GWAS data of females only. Again, there was a significant effect of leptin levels on the risk of AN (e.g. IVW b = −0.826, p = 1.1 × 10−04). MR with genetic instruments from EWAS showed no overall effect of leptin levels on the risk for AN. For the opposite direction, MR revealed no causal effect of AN on leptin levels. If our results are confirmed in extended GWAS data sets, a low endogenous leptin synthesis represents a risk factor for developing AN.
