Does Gender Equality Cause Gender Differences in Values? Reassessing the Gender-Equality-Personality Paradox
Authors: Fors Connolly Filip , Goossen Mikael , Hjerm Mikael 
Published: December 2019

AbstractThe Gender-Equality-Personality Paradox (GEPP) is the finding that gender differences in personality are at their largest in the most gender equal countries. Previous known studies have not examined this relationship over time. Examining this linkage is crucial to our understanding of gender differences and personality development. In the present study, we contrast evolutionary perspectives predicting a gender divergence in personality due to progression in gender equality against biosocial perspectives predicting convergence. Using data from all eight rounds of the European Social Survey (n = 235,339) across 32 European countries, we report three findings. First, in accordance with the evolutionary perspective, country-level gender equality is positively associated with gender differences in basic human values. Second, in accordance with the biosocial perspective, we find evidence supporting gender convergence in basic human values. Third, contradicting both evolutionary and biosocial assumptions, we find no evidence that gender equality causes gender differences in values. We argue that there is a need to explore alternative explanations to the observed cross-sectional association between gender equality and personality differences, as well as gender convergence in personality over time.
Quality attribute trade-offs in the embedded systems industry: an exploratory case study
Authors: Sas Darius , Avgeriou Paris 
Published: December 2019

AbstractThe embedded systems domain has grown exponentially over the past years. The industry is forced by the market to rapidly improve and release new products to beat the competition. Frenetic development rhythms thus shape this domain and give rise to several new challenges for software design and development. One of them is dealing with trade-offs between run-time and design-time quality attributes. To study practices, processes and tools concerning the management of run-time and design-time quality attributes as well as the trade-offs among them from the perspective of embedded systems software engineers. An exploratory case study with two qualitative data collection steps, namely interviews and a focus group, involving six different companies from the embedded systems domain with a total of twenty participants. The interviewed subjects showed a preference for run-time over design-time qualities. Trade-offs between design-time and run-time qualities are very common, but they are often implicit, due to the lack of adequate monitoring tools and practices. Practitioners prefer to deal with trade-offs in the most lightweight way possible, by applying ad-hoc practices, thus avoiding any overhead incurred. Finally, practitioners have elaborated on how they envision the ideal tool support for dealing with trade-offs. Although it is notoriously difficult to deal with trade-offs, constantly monitoring the quality attributes of interest with automated tools is key in making explicit and prudent trade-offs and mitigating the risk of incurring technical debt.

Regulation des Angstverhaltens — zur Rolle neuronaler Netzwerke
Authors: Dedic Nina , Deussing Jan M. 
Published: December 2019

AbstractThe corticotropin-releasing hormone (CRH) system orchestrates the organism’s stress response including the regulation of adaptive be haviours. Here we describe a novel neuronal circuit, which acts anxiety suppressing and positively modulates dopamine release. This anxiolytic circuit comprises inhibitory CRH-expressing, long-range projection neurons within the extended amygdala. These neurons innervate the ventral tegmental area, a prominent brain reward center that expresses high levels of CRH receptor type 1.
Hitchhikers on floats to Arctic freshwater: Private aviation and recreation loss from aquatic invasion
Authors: Schwoerer Tobias , Little Joseph M. , Schmidt Jennifer I. , Borash Kyle W. 
Published: December 2019

AbstractThis study of aviation-related recreation loss shows that a survey primarily aimed at collecting information on invasive species’ pathways can also be used to estimate changes in pathway-related ecosystem services. We present a case study for Elodea spp. (elodea), Alaska’s first known aquatic invasive plant, by combining respondents’ stated pre-invasion actual flights with stated post-invasion contingent behavior, plane operating costs, and site quality data. We asked pilots about the extent of continued flights should destinations become invaded and inhibit flight safety. We estimate a recreation demand model where the lost trip value to the average floatplane pilot whose destination is an elodea-invaded lake is US$185 (95 % CI $157, $211). Estimates of ecosystem damages incurred by private actors responsible for transmitting invaders can nudge actors to change behavior and inform adaptive ecosystem management. The policy and modeling implications of quantifying such damages and integration into more complex models are discussed.
Organosilicon polymer-derived ceramics: An overview
Authors: Fu Shengyang , Zhu Min , Zhu Yufang 
Published: December 2019

AbstractPolymer-derived ceramics (PDCs) strategy shows a great deal of advantages for the fabrication of advanced ceramics. Organosilicon polymers facilitate the shaping process and different silicon-based ceramics with controllable components can be fabricated by modifying organosilicon polymers or adding fillers. It is worth noting that silicate ceramics can also be fabricated from organosilicon polymers by the introduction of active fillers, which could react with the produced silica during pyrolysis. The organosilicon polymer-derived ceramics show many unique properties, which have attracted many attentions in various fields. This review summarizes the typical organosilicon polymers and the processing of organosilicon polymers to fabricate silicon-based ceramics, especially highlights the three-dimensional (3D) printing technique for shaping the organosilicon polymer- derived ceramics, which makes the possibility to fabricate silicon-based ceramics with complex structure. More importantly, the recent studies on fabricating typical non-oxide and silicate ceramics derived from organosilicon polymers and their biomedical applications are highlighted.
Effect of BNNTs/matrix interface tailoring on toughness and fracture morphology of hierarchical SiCf/SiC composites
Authors: Zhu Guangxiang , Feng Qian , Yang Jinshan , Hu Jianbao , Wang Hongda , Xue Yudong , Shan Qingliang , Dong Shaoming 
Published: December 2019

AbstractA thin BN interphase is applied on BNNTs surface to tailor the interfacial bonding between BNNTs and SiC matrix in hierarchical SiCf/SiC composites. The thickness of BN interphase ranging from 10 to 70 nm can be optimized by chemical vapor deposition after BNNTs are in situ grown on SiC fiber surface. Without BN interphase, the fracture toughness of hierarchical SiCf/SiC composites can be impaired by 13.6% due to strong interfacial bonding. As long as BN interphase with 30–45 nm thickness is applied, the interfacial bonding can be optimized and fracture toughness of hierarchical composites can be improved by 27.3%. It implies that tailoring BNNTs/matrix interface by depositing a layer of BN interphase is in favor of activating energy dissipation mechanisms at nanoscale induced by BNNTs.

Published: December 2019

AbstractIt is important to investigate the mechanical performances of (Gd0.9Yb0.1)2Zr2O7 (GYbZ) materials deposited on irregular substrates for improving new thermal barrier coatings. Three-point bending fracture characteristics of freestanding GYbZ coating prepared by supersonic plasma sprayed (SPS) technique were investigated with the help of digital image correlation technique. The cracking time, crack propagation path, and mechanical properties of GYbZ coating were obtained. Meanwhile, the X-ray computed tomography technique was introduced to scan the microstructure of freestanding GYbZ coatings, which are used to establish three-dimensional (3D) finite element model by using the Avizo software. The brittle cracking criterion was applied to describe the bending fracture process of GYbZ coatings. The critical cracking strain was estimated as 0.36%±0.03% by repeatedly comparing the difference between the experimental and simulated curves. The results would be extended to predict the dangerous region and failure mechanisms of GYbZ coatings deposited on irregular substrate during finite element simulations.
Determination of the load-independent hardness by analyzing the nanoindentation loading curves: A case study on fused silica
Authors: Duan Yunbiao , Jiang Danyu , Hu Jin 
Published: December 2019

AbstractThe nanoindentation loading curves measured on fused silica were analyzed based on the theoretical relationship derived by Malzbender et al. (J Mater Res 2000, 15: 1209–1212). It was found that the ratio of the applied load to the square of the displacement, P/(h + hd)2, does not keep constant during loading segment of the nanoindentation test. Considering the existence of the indentation size effect, an empirical method for the determination of the load-independent hardness by analyzing the nanoindentation loading curves was proposed.
‘I Can Do It’ Becomes ‘We Do It’: Kimberley (Australia) and Still Bay (South Africa) Points Through a Socio-technical Framework Lens
Authors: Högberg Anders , Lombard Marlize 
Published: December 2019

AbstractBuilding on the body of work regarding the concepts of invention and innovation in lithic technology, we further explore the give-and-take relationship between people and their technologies in two different stone point knapping traditions. From the socio-technical framework perspective, which is one amongst many ways to look at technological trends, the acceptance and stabilisation of a tool-making tradition is not only dictated by its technology-specific properties, such as its ingenuity or usefulness. Instead, it also depends on the social conventions and practices of its spatiotemporal context, which can be explored through the notions of introduction, closure, stabilisation, destabilisation and copying. We explain the theory behind the socio-technical framework with modern examples, such as bicycle use in late nineteenth century England and electrical guitar trends in the last half of the twentieth century. Turning our attention to stone point knapping, we use Australian Kimberley point production during the late nineteenth and twentieth centuries to bridge into how the socio-technical framework reflects in the dynamics that might be involved in lithic traditions. Using this theoretical framework to think about aspects of deep-time point production, such as that recorded from the Still Bay techno-complex during the Middle Stone Age in southern Africa, becomes trickier though. Instead of reliable ethno-historical accounts or dense archaeological context, we have to rely on coarse-grained data sets about distribution, age, environment and population, making inferences more speculative and less testable. In the context of this special volume, we suggest, however, that a socio-technical framework approach may be a useful tool to enhance our thinking about dynamics in ancient techno-behaviours and that more work is necessary to flesh out its potential in this respect.
An American Führer? Nazi Analogies and the Struggle to Explain Donald Trump
Authors: Rosenfeld Gavriel D. 
Published: December 2019

AbstractEver since Donald Trump announced his candidacy for the US presidency in June 2015, journalists, scholars, and other commentators in the United States have attempted to explain his political success with the aid of historical analogies. In so doing, they have sparked a wider debate about whether the Nazi past helps to make sense of the US present. One group in the debate has contended that Trump's ascent bears a worrisome resemblance to interwar European fascism, especially the National Socialist movement of Adolf Hitler. By contrast, a second group has rejected this comparison and sought analogies for Trump in other historical figures from European and US history. This article surveys the course, and assesses the results, of the debate from its origins up to the present day. It shows that historians of Germany have played a prominent role in helping to make sense of Trump, but notes that their use of Nazi analogies may be distorting, rather than deepening, our understanding of contemporary political trends. By examining the merits and drawbacks of Nazi analogies in present-day popular discourse, the article recommends that scholars draw on both the German and American historical experience in order to best assess the United States's present political movement.
The policy and policing of language in schools
Authors: Cushing Ian 
Published: December 2019

ABSTRACTThis study investigates cases of language ‘policing’ as educational language policies, and the way that these are represented across different policy levels. Focusing on UK schools and using discursive approaches to language policy as a theoretical framework, I critically examine the motivations and justifications that institutions provide for designing and implementing policies whereby nonstandardised forms are ‘banned’, and how these are reported in metalinguistic discourse. Drawing on a range of data including media discourse, policy documents, teacher interviews and linguistic landscapes, I textually trace how educational language policies (re)produce prescriptive and linguicist ideologies, often using metaphors of crime, and often using language as a proxy for social factors such as academic achievement, employability, and standards. Overall, I argue that micro- and meso-level language policies are a partial product of the linguistic conservatism as found within current macro-level educational policy.

Published: December 2019

AbstractDetecting and recognizing objects is one of the most important uses of vision systems in nature and is consequently highly evolved. This paper aims to accurately detect an object using its shape and color information from a complex background. In particular, we evaluated our algorithm to detect 19 different integrated circuits (IC) from 10 different printed circuit boards (PCB) of different colors. We have compared three different shape descriptors for four different color space models. We have evaluated shape detection algorithms in different lighting conditions (indoor, outdoor, and controlled light source) to find suitable illumination for image acquisition. We undertook statistical hypothesis testing to find the effect of color space models and shape descriptors on the accuracy, false positive and false negative rates. While measuring accuracy, we have noted that L*a*b* color space is significantly worse, and the best result is obtained in YCbCr color space using bounding box shape descriptors for 2500 Lux using LED.
Democracy belief systems in Europe: cognitive availability and attitudinal constraint
Authors: Hernández Enrique 
Published: December 2019

AbstractThere is a growing interest in analyzing what citizens think about democracy. However, gauging citizens’ opinions about a complex concept such as democracy might be hindered by the apparent low levels of political sophistication of mass publics. This paper contributes to the emerging literature on citizens’ views and evaluations of democracy by analyzing to what extent ordinary citizens are capable of developing structured opinions about democracy and its constitutive principles. For this purpose, the paper adapts Converse’s notion of political belief systems to analyze the articulation of individuals’ democracy belief systems (DBS). The first goal of this paper is to conceptualize and operationalize the main components of individuals’ DBS: cognitive availability, horizontal constraint, and vertical constraint. Drawing on data from the sixth round of the European Social Survey, the second goal is to describe the articulation of DBS in Europe. The third and final aim of this paper is to trace the most relevant individual- and country-level correlates of the articulation of the three components of DBS. In line with recent findings about political belief systems in other policy domains, the results indicate that most Europeans have coherently structured attitudes about democracy. However, even if the results imply that Europeans have a relatively articulated DBS, the empirical analysis also reveals some individual- and country-level variation in the articulation of specific components of DBS.

Evaluating the Performance of Past Climate Model Projections
Authors: Hausfather Zeke , Drake Henri F. , Abbott Tristan , Schmidt Gavin A. 
Published: December 2019

AbstractRetrospectively comparing future model projections to observations provides a robust and independent test of model skill. Here we analyze the performance of climate models published between 1970 and 2007 in projecting future global mean surface temperature (GMST) changes. Models are compared to observations based on both the change in GMST over time and the change in GMST over the change in external forcing. The latter approach accounts for mismatches in model forcings, a potential source of error in model projections independent of the accuracy of model physics. We find that climate models published over the past five decades were skillful in predicting subsequent GMST changes, with most models examined showing warming consistent with observations, particularly when mismatches between model‐projected and observationally estimated forcings were taken into account.
The 2013 and 2017 Ms 5 Seismic Swarms in Jilin, NEChina: Fluid‐Triggered Earthquakes?
Authors: Zhang Guangwei , Lei Jianshe , Sun Daoyuan 
Published: December 2019

AbstractUnderstanding the mechanism of moderate earthquake swarm is important for the time‐dependent hazard assessment. Five Ms ≥ 5.0 earthquakes occurred between October and November 2013 in Qianguo, Jilin, a region with low seismicity in northeast China. After 4 years, two more Ms > 5.0 earthquakes struck Ningjiang, Jilin. To investigate the swarm mechanism and the relationship between these two swarm activities, we determine the full moment tensor solutions for 12 Ms > 3.5 earthquakes, including the seven Ms ≥ 5.0 events. The focal mechanisms show that the 2013 Ms ≥ 5.0 events mostly exhibit thrust compression with significant volume closure components, whereas the 2017 Ms ≥ 5.0 earthquakes illustrate a dominated strike‐slip type. In order to explain such differences, we conduct double‐difference tomography in the study region. Our tomographic results reveal that both swarms are located in the low‐velocity zones and the fault materials exhibit structural variations along the strike, possibly indicating that the structural contrast could be critical for the variations in the focal mechanism and hypocenter migration. The faults provide pathways for the upward intrusion of fluids that control the distribution and migration of the swarm sequences. A long‐term fluid‐rock interaction could lead to the fault materials intensely fractured in the 2013 swarm area but relatively less damaged in the 2017 swarm area. We can conclude that fluids play an important role in triggering the two seismic swarms.
Interpreting the Difference in Magnitudes of PETM Carbon Isotope Excursions in Paleosol Carbonate and Organic Matter: Oxidation of Methane in Soils Versus Elevated Soil Respiration Rates
Authors: Gallagher Timothy M. , Cacciatore Christopher G. , Breecker Daniel O. 
Published: December 2019

Key Points

Possible mechanisms that could explain larger‐magnitude carbon isotope excursions in paleosol carbonate than organic matter are evaluated
Oxidation of methane in soil pore spaces is an unlikely explanation for the main excursion but may help explain the preonset excursion
At least a 4 times increase in soil respiration rates is required to explain the larger carbon isotope excursion in paleosol carbonate
A Re‐evaluation of the Plenus Cold Event, and the Links Between CO2, Temperature, and Seawater Chemistry During OAE 2

Published: December 2019

AbstractThe greenhouse world of the mid‐Cretaceous (~94 Ma) was punctuated by an episode of abrupt climatic upheaval: Oceanic Anoxic Event 2. High‐resolution climate records reveal considerable changes in temperature, carbon cycling, and ocean chemistry during this climatic perturbation. In particular, an interval of cooling has been detected in the English Chalk on the basis of an invasive boreal fauna and bulk oxygen‐isotope excursions registered during the early stages of Oceanic Anoxic Event 2—a phenomenon known as the Plenus Cold Event, which has tentatively been correlated with climatic shifts worldwide. Here we present new high‐resolution neodymium‐, carbon‐, and oxygen‐isotope data, as well as elemental chromium concentrations and cerium anomalies, from the English Chalk exposed at Dover, UK, which we evaluate in the context of >400 records from across the globe. A negative carbon‐isotope excursion that correlates with the original “Plenus Cold Event” is consistently expressed worldwide, and CO2 proxy records, where available, indicate a rise and subsequent fall in CO2 over the Plenus interval. However, variability in the timing and expression of cooling at different sites suggests that, although sea‐surface paleotemperatures may reflect a response to global CO2 change, local processes likely played a dominant role at many sites. Variability in the timing and expression of changes in water mass character, and problems in determining the driver of observed proxy changes, suggest that no single simple mechanism can link the carbon cycle to oceanography during the Plenus interval and other factors including upwelling and circulation patterns were locally important. As such, it is proposed that the Plenus carbon‐isotope event is a more reliable stratigraphic marker to identify the Plenus interval, rather than any climatic shifts that may have been overprinted by local effects.
