[more ▼]The recent expansion of Islamic banks raises questions on its economic implications. The aim of this paper is to investigate the impact of Islamic banking development on access to credit. We combine data from a unique hand-collected database that covers Islamic banks with firm-level data covering developing and emerging countries over the period of 2006 to 2009. We find that Islamic banking development has overall no impact on credit constraints, while banking development and conventional banking development alleviate obstacles to financing. However Islamic banking development exerts a positive impact on access to credit when conventional banking development is low. Hence we support the view that Islamic banking does not overall alleviate obstacles to financing, but it can act as substitute to conventional banking.

[more ▼]The test case generation is intrinsically a multi-objective problem, since the goal is covering multiple test targets (e.g., branches). Existing search-based approaches either consider one target at a time or aggregate all targets into a single fitness function (whole-suite approach). Multi and many-objective optimisation algorithms (MOAs) have never been applied to this problem, because existing algorithms do not scale to the number of coverage objectives that are typically found in real-world software. In addition, the final goal for MOAs is to find alternative trade-off solutions in the objective space, while in test generation the interesting solutions are only those test cases covering one or more uncovered targets. In this paper, we present DynaMOSA (Dynamic Many-Objective Sorting Algorithm), a novel many-objective solver specifically designed to address the test case generation problem in the context of coverage testing. DynaMOSA extends our previous many-objective technique MOSA (Many-Objective Sorting Algorithm) with dynamic selection of the coverage targets based on the control dependency hierarchy. Such extension makes the approach more effective and efficient in case of limited search budget. We carried out an empirical study on 346 Java classes using three coverage criteria (i.e., statement, branch, and strong mutation coverage) to assess the performance of DynaMOSA with respect to the whole-suite approach (WS), its archive-based variant (WSA) and MOSA. The results show that DynaMOSA outperforms WSA in 28% of the classes for branch coverage (+8% more coverage on average) and in 27% of the classes for mutation coverage (+11% more killed mutants on average). It outperforms WS in 51% of the classes for statement coverage, leading to +11% more coverage on average. Moreover, DynaMOSA outperforms its predecessor MOSA for all the three coverage criteria in 19% of the classes with +8% more code coverage on average.

[more ▼]This paper proposes a new methodology to guarantee the accuracy of the homogenisation schemes that are traditionally employed to approximate the solution of PDEs with random, fast evolving diffusion coefficients. We typically consider linear elliptic diffusion problems in randomly packed particulate composites. Our work extends the pioneering work presented in [26,32] in order to bound the error in the expectation and second moment of quantities of interest, without ever solving the fine-scale, intractable stochastic problem. The most attractive feature of our approach is that the error bounds are computed without any integration of the fine-scale features. Our computations are purely macroscopic, deterministic, and remain tractable even for small scale ratios. The second contribution of the paper is an alternative derivation of modelling error bounds through the Prager-Synge hypercircle theorem. We show that this approach allows us to fully characterise and optimally tighten the interval in which predicted quantities of interest are guaranteed to lie. We interpret our optimum result as an extension of Reuss-Voigt approaches, which are classically used to estimate the homogenised diffusion coefficients of composites, to the estimation of macroscopic engineering quantities of interest. Finally, we make use of these derivations to obtain an efficient procedure for multiscale model verification and adaptation.

[more ▼]Study Objectives: The aim of the present paper is to investigate the determinants of sleeping patterns in children up to age 9 on a large and geographically homogeneous sample of British children and parents, focusing in particular on the role of economic and social factors, specifically on income. Methods: The data of this study come from the Avon Longitudinal Study of Parents and Children, a long-term health research project that recruited over 14,000 pregnant women who were due to give birth between April 1991 and December 1992 in Bristol and its surrounding areas, including some of Somerset and Gloucestershire. Logistic regression models for the sleep problems dummies and log-linear models for the sleep quantity. Results: One additional item in the material deprivation index is associated to an increase of around 10% to 20% in the odds of having at least one sleep problem. Similarly, children from the richest families are less likely to have any sleep problem up to 115 months (around 20% reduction in the odds). Mother’s characteristics (i.e. education and mental health in the pregnancy period) are also significant predictors. Sleep quantity does not vary much and is not sensitive to socioeconomic factors. Conclusion: Exposure to income-related inequalities affects child sleep. Further research is needed in order to understand if sleep in early life influence future health and economic trajectories.

[more ▼]This paper examines 25 lecture listening coursebooks for their representativeness of ‘real’ lectures with a view to helping EAP practitioners make informed decisions about materials selection and development. The aspects of representativeness examined are language, lecture authenticity and research-informedness. For the analysis of language, signposts of important points in the coursebooks are compared with those retrieved from a corpus of 160 authentic lectures. The EAP lectures are analysed in terms of their source, delivery and length. The materials are also reviewed for their use of findings from research into listening comprehension and lecture discourse. Results suggest that current lecture listening materials often do not reflect the language and lectures students are likely encounter on their degree programmes. Moreover, materials are typically not (systematically) informed by listening and lecture discourse research. These findings highlight the need for EAP practitioners to approach published materials critically and supplement or modify them in ways that would better serve students. The paper concludes with recommendations on how this could be done.

[more ▼]Intrinsic volumes of convex sets are natural geometric quantities that also play important roles in applications, such as linear inverse problems with convex constraints, and constrained statistical inference. It is a well-known fact that, given a closed convex cone $C\subset \mathbb{R}^d$, its conic intrinsic volumes determine a probability measure on the finite set $\{0,1,...d\}$, customarily denoted by $\mathcal{L}(V_C)$. The aim of the present paper is to provide a Berry-Esseen bound for the normal approximation of ${\cal L}(V_C)$, implying a general quantitative central limit theorem (CLT) for sequences of (correctly normalised) discrete probability measures of the type $\mathcal{L}(V_{C_n})$, $n\geq 1$. This bound shows that, in the high-dimensional limit, most conic intrinsic volumes encountered in applications can be approximated by a suitable Gaussian distribution. Our approach is based on a variety of techniques, namely: (1) Steiner formulae for closed convex cones, (2) Stein's method and second order Poincar\'e inequality, (3) concentration estimates, and (4) Fourier analysis. Our results explicitly connect the sharp phase transitions, observed in many regularised linear inverse problems with convex constraints, with the asymptotic Gaussian fluctuations of the intrinsic volumes of the associated descent cones. In particular, our findings complete and further illuminate the recent breakthrough discoveries by Amelunxen, Lotz, McCoy and Tropp (2014) and McCoy and Tropp (2014) about the concentration of conic intrinsic volumes and its connection with threshold phenomena. As an additional outgrowth of our work we develop total variation bounds for normal approximations of the lengths of projections of Gaussian vectors on closed convex sets.

[more ▼]We study a pair trading strategy that utilizes short-term return reversals in the stock market. Using U.S. data, we show that returns to our pair trading strategy exceed reasonable estimates for transaction costs. The strategy also generates positive alpha when controlling for the standard risk factors. Second, using transaction level data from Finland, focusing on a popular pair, we provide evidence that these kinds of pair trading returns are compensation from providing liquidity. On the days when the expected returns to our pair trading strategy are the highest, the trading volume is abnormally high and, judging from active brokers’ net trades, nearly 45% of all brokers (or their customers) engage in pair trading in accordance with our trading strategy. These brokers are mainly counterparties to few brokers that trade large quantities of stocks inconsistent with our strategy.

[more ▼]In many domains such as automotive and avionics, the size and complexity of software systems is quickly increasing. At the same time, many stakeholders tend to be involved in the development of such systems, which typically must also be configured for multiple customers with varying needs. Product Line Engineering (PLE) is therefore an inevitable practice for such systems. Furthermore, because in many areas requirements must be explicit and traceability to them is required by standards, use cases and domain models are common practice for requirements elicitation and analysis. In this paper, based on the above observations, we aim at supporting PLE in the context of use case-centric development. Therefore, we propose, apply, and assess a use case-driven configuration approach which interactively receives configuration decisions from the analysts to generate Product Specific (PS) use case and domain models. Our approach provides the following: (1) a use case-centric product line modeling method (PUM), (2) automated, interactive configuration support based on PUM, and (3) an automatic generation of PS use case and domain models from Product Line (PL) models and configuration decisions. The approach is supported by a tool relying on Natural Language Processing (NLP), and integrated with an industrial requirements management tool, i.e., IBM Doors. We successfully applied and evaluated our approach to an industrial case study in the automotive domain, thus showing evidence that the approach is practical and beneficial to capture variability at the appropriate level of granularity and to configure PS use case and domain models in industrial settings.

[more ▼]Businesses increasingly offer their services electronically via the Web. Take for example an Internet Service Provider. An ISP offers a variety of services, including raw bandwidth, IP connectivity, and Domain Name resolution. Although in some cases a single service already satisfies a customer need, in many situations a customer need is so complex that a bundle of services is needed to satisfy the need, as with the ISP example. In principle, each service in a bundle can be provisioned by a different supplier. This paper proposes an ontology, e3service , that can be used to formally capture customer needs, services, and multisupplier service bundles of these. In addition, this paper contributes a process called PCM2 to reason with the ontology. First, a customer need is identified for which desired consequences are elicited. Then, the desired set of consequences is matched with consequences associated with services. The matching process results in a service bundle, satisfying the customer need, containing services that each can be provided by different suppliers. PCM2 is inspired by a family of formal reasoning methods called Propose-Critique-Modify (PCM). However, whereas PCM methods emphasize solution generation from a given set of requirements, our reasoning process treats the space of requirements as a first class citizen. Hence PCM2 : the requirements space and solution space are equally important. How the reasoning and matching process practically works, is illustrated by an industry strength case study in the healthcare domain.

[more ▼]On surveys that assess sensitive personal attributes, indirect questioning aims at increasing respondents’ willingness to answer truthfully by protecting confidentiality. However, the assumption that subjects understand questioning procedures fully and trust them to protect their privacy is tested rarely. In a scenario-based design, we compared four indirect questioning procedures in terms of comprehensibility and perceived privacy protection. All indirect questioning techniques were found less comprehensible for respondents than a conventional direct question used for comparison. Less-educated respondents experienced more difficulties when confronted with any indirect questioning technique. Regardless of education, the Crosswise Model was found most comprehensible among the four indirect methods. Indirect questioning was perceived to increase privacy protection in comparison to a direct question. Unexpectedly, comprehension and perceived privacy protection did not correlate. We recommend assessing these factors separately in future evaluations of indirect questioning.

[more ▼]A certain type of counterfactual is thought to be intimately related to causation, control, and explanation. The time asymmetry of these phenomena therefore plausibly arises from a time asymmetry of counterfactual dependence. But why is counterfactual dependence time asymmetric? The most influential account of the time asymmetry of counterfactual dependence is David Albert’s account, which posits a new, time-asymmetric fundamental physical law, the so-called “past hypothesis.” Albert argues that the time asymmetry of counterfactual dependence arises from holding fixed the past hypothesis when evaluating counterfactuals. In this paper, I argue that Albert’s account misconstrues the time asymmetry of counterfactual dependence.

[more ▼]Educational research in Norway has experienced unprecedented structural expansion as well as cognitive shifts over the past two decades, especially due to increased state investments and the strategic use of extensive and multi-year thematic programs to fund research projects. Applying a neo-institutionalist framework, we examine institutionalization dynamics in cultural-cognitive, normative, and regulative dimensions over the past two decades using interviews, research program calls, policy documents, and funding data. In the cultural-cognitive dimension, we find references to the knowledge society, the importance of evidence in policy-making, and ideas of quality, excellence, and relevance. In the normative dimension, we find the introduction of new professional and methodological standards, reflecting broader global patterns of academic and epistemic drift. In the regulative dimension, the strengthened role of both government and the Research Council of Norway is manifest in substantial growth in both funding and large-scale, long-term planning, including thematic choices—evidence of ‘programification’. The importance of external models has grown in an era of internationalization, yet translation occurs at every level of governance of educational research. This results in a specific Norwegian research model, guided by a mode of governance of programs, that maintains social values traditionally strong in Nordic societies.

[more ▼]A glossary is an important part of any software requirements document. By making explicit the technical terms in a domain and providing definitions for them, a glossary helps mitigate imprecision and ambiguity. A key step in building a glossary is to decide upon the terms to include in the glossary and to find any related terms. Doing so manually is laborious, particularly for large requirements documents. In this article, we develop an automated approach for extracting candidate glossary terms and their related terms from natural language requirements documents. Our approach differs from existing work on term extraction mainly in that it clusters the extracted terms by relevance, instead of providing a flat list of terms. We provide an automated, mathematically-based procedure for selecting the number of clusters. This procedure makes the underlying clustering algorithm transparent to users, thus alleviating the need for any user-specified parameters. To evaluate our approach, we report on three industrial case studies, as part of which we also examine the perceptions of the involved subject matter experts about the usefulness of our approach. Our evaluation notably suggests that: (1) Over requirements documents, our approach is more accurate than major generic term extraction tools. Specifically, in our case studies, our approach leads to gains of 20% or more in terms of recall when compared to existing tools, while at the same time either improving precision or leaving it virtually unchanged. And, (2) the experts involved in our case studies find the clusters generated by our approach useful as an aid for glossary construction.

As the entrepreneurs’ initial motivations to startup are likely to influence their subsequent entrepreneurial behavior, this study aims to explore whether and how entrepreneurial motivations affect diversified innovation behavior in startups. Using data on over 48.000 French startups, we present novel insights into the consequences of entrepreneurial motivation for innovation behavior. In fact, we find that distinct startup motivations can have different effects on the development of diverse innovations. As such, our findings contribute to extant research on innovation development of startups and advance the present understanding of the determinants of startups’ innovative behavior [less ▲]Detailed reference viewed: 33 (1 UL) Europeans and Americans in Korea, 1882-1910: A Bourgeois and Translocal CommunityDittrich, Klaus in Itinerario (in press), 39(3), This article deals with the European and American community in Korea between the conclusion of Korea’s first international treaties in the early 1880s and the country’s annexation by the Japanese Empire ...

[more ▼]Some people have serious problems controlling their Internet and video game use. The DSM-5 now includes a proposal for 'Internet Gaming Disorder' (IGD) as a condition in need of further study. Various studies aim to validate the proposed diagnostic criteria for IGD and multiple new scales have been introduced that cover the suggested criteria. Using a structured approach, we demonstrate that IGD might be better interpreted as a formative construct, as opposed to the current practice of conceptualizing it as a reflective construct. Incorrectly approaching a formative construct as a reflective one causes serious problems in scale development, including: (i) incorrect reliance on item-to-total scale correlation to exclude items and incorrectly relying on indices of inter-item reliability that do not fit the measurement model (e.g., Cronbach's alpha); (ii) incorrect interpretation of composite or mean scores that assume all items are equal in contributing value to a sum score; and (iii) biased estimation of model parameters in statistical models. We show that these issues are impacting current validation efforts through two recent examples. A reinterpretation of IGD as a formative construct has broad consequences for current validation efforts and provides opportunities to reanalyze existing data. We discuss three broad implications for current research: (i) composite latent constructs should be defined and used in models; (ii) item exclusion and selection should not rely on item-to-total scale correlations; and (iii) existing definitions of IGD should be enriched further.

This state estimator is the optimal one-step estimate that takes values in a fixed finite dimensional subspace of the system’s state space — consider, for example, a Finite Element space. The structure of the obtained state estimator is like the Kalman filter, but with an additional optimal embedding operator mapping from the reduced space to the original state space. We derive a Riccati difference equation for the error covariance and use sensitivity analysis to obtain a bound for the error of the state estimate due to the state space discretization.

[more ▼]The present study investigated the predictive role of spatial skills for arithmetic and number line estimation in kindergarten children (N = 125). Spatial skills are known to be related to mathematical development, but due to the construct’s non-unitary nature, different aspects of spatial skills need to be differentiated. In the present study, a spatial orientation task, a spatial visualization task and visuo-motor integration task were administered to assess three different aspects of spatial skills. Furthermore, we assessed counting abilities, knowledge of Arabic numerals, quantitative knowledge, as well as verbal working memory and verbal intelligence in kindergarten. Four months later, the same children performed an arithmetic and a number line estimation task to evaluate how the abilities measured at time 1 predicted early mathematics outcomes. Hierarchical regression modelling revealed that children’s performance in arithmetic was predicted by their performance in the spatial orientation and Visuo-motor integration task, as well as their knowledge of the Arabic numerals. Performance in number line estimation was significantly predicted by the children’s spatial orientation performance. Our findings emphasize the role of spatial skills, notably spatial orientation, in mathematical development. The relation between spatial orientation and arithmetic was partially mediated by the number line estimation task. Our results further show that some aspects of spatial skills might be more predictive of mathematical development than others, underlining the importance to differentiate within the construct of spatial skills when it comes to understanding numerical development.

[more ▼]Since the Treaty of Lisbon, the desire of parliaments to adapt to their new powers has led to a new wave of Europeanization (Hefftler et al. 2015). However, the Early Warning System (EWS) and the Political Dialogue with the Commission only constitute one small part of parliamentary scrutiny for regional parliaments, which still largely rely on traditional tools such as mandates, debates and questions. Therefore, this paper studies a traditional mechanism of scrutiny, parliamentary questions, in order to understand the degree of Europeanization of regional parliaments and their interest in different parliamentary functions more fully. The study shows that the Europeanization of traditional scrutiny mechanisms is progressing slowly, but also that the proportion of MPs who ask EU-related questions is now relatively high. The vast majority of these MPs are not members of the European Affairs Committee. The main functions of parliamentary questions are a representative function and information function. Finally, the focus and content of parliamentary questions show that regional parliaments do indeed have a distinctive territorial approach to EU affairs.

[more ▼]Risky and excessive behaviors, such as aggressive and compulsive behaviors, are frequently described in patients with brain damage and have dramatic psychosocial consequences. Although there is strong evidence that impulsivity constitutes a key factor at play in these behaviors, the literature about impulsivity in neuropsychology is to date scarce. In addition, examining and understanding these problematic behaviors requires the assumption that impulsivity is a multidimensional construct. Consequently, this article aims at shedding light on frequent risky and excessive behaviors in patients with brain damage by focusing on a unified, comprehensive, and well-validated model, namely, the UPPS model of impulsivity (Whiteside & Lynam, 2001). This model considers impulsivity as a multidimensional construct that includes four facets: urgency, (lack of) premeditation, (lack of) perseverance, and sensation seeking. Furthermore, we discuss the psychological mechanisms underlying the dimensions of impulsivity, as well as the laboratory tasks designed to assess each mechanism and their neural bases. We then present a scale specifically designed to assess these four dimensions of impulsivity in patients with brain damage and examine the data regarding this multidimensional approach to impulsivity in neuropsychology. This review supports the need to adopt a multifactorial and integrative approach toward impulsive behaviors, and the model presented provides a valuable rationale to disentangle the nature of brain systems and mechanisms underlying impulsive behaviors in patients with brain damage. It may also foster further relevant research in the field of impulsivity and improve assessment and rehabilitation of impulsive behaviors in clinical settings.

[more ▼]We developed a cued pro- and antisaccade paradigm (CPAP) to explore automatic components of sexual interest. Heterosexual participants (n = 32 women, n = 25 men) had to perform fast eye movements towards and away from sexually relevant or irrelevant stimuli across a congruent (i.e. prosaccade towards sexually relevant stimuli, antisaccade away from sexually irrelevant stimuli) and an incongruent condition (i.e. prosaccade towards sexually irrelevant stimuli, antisaccade away from sexually relevant stimuli). We hypothesized that pro- and antisaccade performance would be influenced by the sexual interest-specific relevance of the presented stimulus (i.e., nude female or male stimulus) and the instructed task (i.e., pro- or antisaccade) and, thus, differ meaningfully between conditions. Results for prosaccades towards sexually relevant stimuli in the congruent condition showed that error rates were lower and latencies were shorter compared with prosaccades towards sexually irrelevant stimuli in the incongruent condition, but only for male participants. In addition, error rates for antisaccades away from sexually irrelevant stimuli in the congruent condition were lower than for antisaccades away from sexually relevant stimuli in the incongruent condition, for both female and male participants. Latencies of antisaccades, however, did not differ between conditions. In comparison with established indirect sexual interest paradigms, the CPAP benefits from measuring highly automated processes less prone to deliberate control. To this end, the CPAP could be applied to explore the interplay of early automatic and deliberate components of sexual information processing.

[more ▼]Numerical modeling of fluids in pipes or network of pipes (like in the circulatory system) has been recently faced with new methods that exploit the specific nature of the dynamics, so that a one dimensional axial mainstream is enriched by local secondary transverse components [4, 16, 18]. These methods - under the name of Hi-Mod approximation - construct a solution as a finite element axial discretization, completed by a spectral approximation of the transverse dynamics. It has been demonstrated that Hi-Mod reduction significantly accelerates the computations without com- promising the accuracy. In view of variational data assimilation procedures (or, more in general, control problems), it is crucial to have efficient model reduction techniques to rapidly solve, for instance, a parametrized problem for several choices of the parameters of interest. In this work, we present some preliminary results merging Hi-Mod techniques with a classical Proper Orthogonal Decomposition (POD) strategy. We name this new approach as Hi-POD model reduction. We demonstrate the efficiency and the reliability of Hi-POD on multiparameter advection-diffusion-reaction problems as well as on the incompressible Navier-Stokes equations, both in a steady and in an unsteady setting.

[more ▼]Pluripotency can be considered a functional characteristic of pluripotent stem cells (PSCs) populations and their niches, rather than a property of individual cells. In this view, individual cells within the population independently adopt a variety of different expression states, maintained by different signaling, transcriptional, and epigenetics regulatory networks. In this review, we propose that generation of integrative network models from single cell data will be essential for getting a better understanding of the regulation of self-renewal and differentiation. In particular, we suggest that the identification of network stability determinants in these integrative models will provide important insights into the mechanisms mediating the transduction of signals from the niche, and how these signals can trigger differentiation. In this regard, the differential use of these stability determinants in subpopulation-specific regulatory networks would mediate differentiation into different cell fates. We suggest that this approach could offer a promising avenue for the development of novel strategies for increasing the efficiency and fidelity of differentiation, which could have a strong impact on regenerative medicine [less ▲]Detailed reference viewed: 102 (11 UL) Toward Omics-Based, Systems Biomedicine, and Path and Drug Discovery Methodologies for Depression-Inflammation ResearchMaes; Nowak, Gabriel; Caso, Javier et alin Molecular Neurobiology (in press)Meta-analyses confirm that depression is accompanied by signs of inflammation including increased levels of acute phase proteins, e.g., C-reactive protein, and pro-inflammatory cytokines, e.g ... [more ▼]Meta-analyses confirm that depression is accompanied by signs of inflammation including increased levels of acute phase proteins, e.g., C-reactive protein, and pro-inflammatory cytokines, e.g., interleukin-6. Supporting the translational significance of this, a meta-analysis showed that anti-inflammatory drugs may have antidepressant effects. Here, we argue that inflammation and depression research needs to get onto a new track. Firstly, the choice of inflammatory biomarkers in depression research was often too selective and did not consider the broader pathways. Secondly, although mild inflammatory responses are present in depression, other immune-related pathways cannot be disregarded as new drug targets, e.g., activation of cell-mediated immunity, oxidative and nitrosative stress (O&NS) pathways, autoimmune responses, bacterial translocation, and activation of the toll-like receptor and neuroprogressive pathways. Thirdly, anti-inflammatory treatments are sometimes used without full understanding of their effects on the broader pathways underpinning depression. Since many of the activated immune-inflammatory pathways in depression actually confer protection against an overzealous inflammatory response, targeting these pathways may result in unpredictable and unwanted results. Furthermore, this paper discusses the required improvements in research strategy, i.e., path and drug discovery processes, omics-based techniques, and systems biomedicine methodologies. Firstly, novel methods should be employed to examine the intracellular networks that control and modulate the immune, O&NS and neuroprogressive pathways using omics-based assays, including genomics, transcriptomics, proteomics, metabolomics, epigenomics, immunoproteomics and metagenomics. Secondly, systems biomedicine analyses are essential to unravel the complex interactions between these cellular networks, pathways, and the multifactorial trigger factors and to delineate new drug targets in the cellular networks or pathways. Drug discovery processes should delineate new drugs targeting the intracellular networks and immune-related pathways.

It describes the common dataset and methods used by an international research team. The chapter synthesizes the results of a series of country-level case studies and cross-national and regional comparisons on the growth of scientific research from 1900 until 2011. Additionally, the chapter provides a quantitative analysis of global trends in scientific, peer-reviewed publishing over the same period. The introduction identifies common themes that emerged across the case studies examined in-depth during the multi-year research project Science Productivity, Higher Education, Research Development and the Knowledge Society (SPHERE). First, universities have long been and increasingly are the primary organizations in science production around the globe. Second, the chapters describe in-country and cross-country patterns of competition and collaboration in scientific publications. Third, the chapters describe the national policy environments and institutionalized organizational forms that fostered scientific research. The introduction reviews selected findings and limitations of previous bibliometric studies and explains that the chapters in the volume overcome these limitations by applying neo-institutional theoretical frameworks to analyze bibliometric data over an extensive period.

[more ▼]Despite growing interest in redesigning the material landscape of education, relatively little is known about the impact of these evolving classrooms. The current study aimed to gain insight into the physical learning environment and the potential pedagogical impacts thereof. A ‘biographical approach’ (c.1963-2015), was used to explore the long-term socio-material landscapes where teachers and pupils, classroom materiality and spatiality, and teaching practices are entangled. Stimulated recall interviews were conducted in Flanders (Belgium) with primary school teachers. Teacher-generated floorplans detailing their material classroom over time, transcribed oral accounts elaborating on these, and supportive data sources were aggregated and thematically analysed. The resulting identification of six key themes shed light on the evolving architectural and infrastructural developments, as well as triggers and teaching impacts thereof amongst the interviewed teachers. Findings show that negative school evaluations urging school intervention, and teachers’ proactive engagement within their classrooms, were the main catalysts of change. Moreover, evolving classroom layouts, in addition to the affordances of upgraded equipment, can be associated to changes in teachers’ practices. It can be concluded that the classroom is becoming an action context as the result of the inextricable mediating agencies identified.

The main findings reveal that inter-regional network proximity is important in determining future collaborations but its effect is mediated by geography. Most importantly, a clear substitution pattern is revealed showing that network proximity mainly benefits international collaborations.

[more ▼]We present a remeshed particle-mesh method for the simulation of three-dimensional compressible turbulent flow. The method is related to the mesh free smoothed particle hydrodynamic (SPH) method, but the present method introduces a mesh for efficient calculation of the pressure gradient, and laminar and turbulent diffusion. In addition, the mesh is used to remesh (reorganise uniformly) the particles to ensure a regular particle distribution and convergence of the method. The accuracy of the presented methodology is tested for a number of benchmark problems involving two- and three-dimensional Taylor-Green flow, thin double shear layer, and three-dimensional isotropic turbulence. Two models were implemented, direct numerical simulations, and Smagorinsky model. Taking advantage of the Lagrangian advection, and the finite difference efficiency, the method is capable of providing quality simulations while maintaining its robustness and versatility.

[more ▼]Regulator of G-Protein Signaling 4 (RGS4), a member of the RGS family of proteins that inactivate G-proteins, has gained interest as a potential drug target for neurological disorders, such as epilepsy and Parkinson’s disease (PD). In the case of PD, the main current option for alleviating motor symptoms are dopamine replacement therapies, which have limitations because of side effects, and reduced effectiveness over the long term. Research on new non-dopaminergic PD drug targets has indicated that inhibition of RGS4 could be an effective adjuvant treatment option. The effectiveness of RGS4 inhibition for an array of PD-linked functional and structural neuroprotection endpoints has not yet been demonstrated. Here, we use the 6-Hydroxydopamine (6-OHDA) lesioning model of the nigrostriatal pathway in mice to address this question. We observe, using a battery of behavioral and pathological measures, that mice deficient for RGS4 are not protected from 6-OHDA induced injury, and show enhanced susceptibility in some measures of motor function. Our results suggest that inhibition of RGS4 as a non-dopaminergic target for PD should be approached with caution.

[more ▼]We propose an iterative method for joint state and parameter estimation using measurements on a time interval [0,T] for systems that are backward output stabilizable. Since this time interval is fixed, errors in initial state may have a big impact on the parameter estimate. We propose to use the back and forth nudging (BFN) method for estimating the system’s initial state and a Gauss–Newton step between BFN iterations for estimating the system parameters. Taking advantage of results on the optimality of the BFN method, we show that for systems with skew-adjoint generators, the initial state and parameter estimate minimizing an output error cost functional is an attractive fixed point for the proposed method. We treat both linear source estimation and bilinear parameter estimation problems.

The aim of this study was twofold: to examine (a) cross-cultural patterns of perceived dependence on mobile phones in ten European countries, first, grouped in four different regions (North: Finland and UK; South: Spain and Italy; East: Hungary and Poland; West: France, Belgium, Germany, and Switzerland), and second by country, and (b) how socio-demographics, geographic differences, mobile phone usage patterns, and associated activities predicted this perceived dependence. Methods A sample of 2,775 young adults (aged 18-29 years) were recruited in different European Universities who participated in an online survey. Measures included socio-demographic variables, patterns of mobile phone use, and the dependence subscale of a short version of the Problematic Mobile Phone Use Questionnaire (PMPUQ; Billieux, Van der Linden, & Rochat, 2008). Results The young adults from the Northern and Southern regions reported the heaviest use of mobile phones, whereas perceived dependence was less prevalent in the Eastern region. However, the proportion of highly dependent mobile phone users was more elevated in Belgium, UK, and France. Regression analysis identified several risk factors for increased scores on the PMPUQ dependence subscale, namely using mobile phones daily, being female, engaging in social networking, playing video games, shopping and viewing TV shows through the Internet, chatting and messaging, and using mobile phones for downloading-related activities. Discussion and conclusions Self-reported dependence on mobile phone use is influenced by frequency and specific application usage.

We examine Linux container technology for the distribution of a non-trivial scientific computing software stack and its execution on a spectrum of platforms from laptop computers through to high performance computing (HPC) systems. We show on a workstation and a leadership-class HPC system that when deployed appropriately there are no performance penalties running scientific programs inside containers. For Python code run on large parallel computers, the run time is reduced inside a container due to faster library imports. The software distribution approach and data that we present will help developers and users decide on whether container technology is appropriate for them.

[more ▼]The competition graph of an acyclic directed graph D is the undirected graph on the same vertex set as D in which two distinct vertices are adjacent if they have a common out-neighbor in D. The competition number of an undirected graph G is the least number of isolated vertices that have to be added to G to make it the competition graph of an acyclic directed graph. We resolve two conjectures concerning competition graphs. First we prove a conjecture of Opsut by showing that the competition number of every quasi-line graph is at most 2. Recall that a quasi-line graph, also called a locally co-bipartite graph, is a graph for which the neighborhood of every vertex can be partitioned into at most two cliques. To prove this conjecture we devise an alternative characterization of quasi-line graphs to the one by Chudnovsky and Seymour. Second, we prove a conjecture of Kim by showing that the competition number of any graph is at most one greater than the number of holes in the graph. Our methods also allow us to prove a strengthened form of this conjecture recently proposed by Kim, Lee, Park and Sano, showing that the competition number of any graph is at most one greater than the dimension of the subspace of the cycle space spanned by the holes.

Despite the political goals to foster innovation and further expand research capacity, in cross-national and historical comparison, neither the level of R&D investments nor country size accounts completely for the differential growth of scientific productivity. Based on a comprehensive historical database, this analysis uncovers both stable and dynamic patterns of productivity from 1975 to 2010 in Ger- many, France, Belgium, and Luxembourg. Measured in peer-reviewed research articles collected in Thomson Reuters Science Citation Index Expanded (SCIE), we show the varying contributions of different organizational forms, especially research universities and research institutes. Comparing the institutionalization pathways that created the conditions necessary for continuous and strong growth in scientific productivity in the European center of global science emphasizes that the research university is key organizational form across countries.

[more ▼]This paper proves the practicality of an iterative algorithm for solving realistic large-scale SCOPF problems. This algorithm is based on the combination of a contingency filtering scheme, used to identify the binding contingencies at the optimum, and a network compression method, used to reduce the complexity of the post-contingency models included in the SCOPF formulation. We show that by combining these two complementary ideas, it is possible to solve in a reasonable time SCOPF problems on large power system models with a large number of contingencies. Unlike most results reported for large-scale SCOPF problems, our algorithm uses a non-linear AC network model in both pre-contingency and post-contingency states, optimizes both active/reactive powers flows jointly, and treats the discrete variables. The proposed algorithm is implemented with state-of-the-art solvers and applied to two systems: a national grid with 2563 buses and 1297 contingencies, and a model of the European transmission network with 9241 buses and 12000 contingencies.

[more ▼]Following the recent changes to the diagnostic category for addictive disorders in DSM-5, it is urgent to clarify what constitutes behavioural addiction to have a clear direction for future research and classification. However, in the years following the release of DSM-5, an expanding body of research has increasingly classified engagement in a wide range of common behaviours and leisure activities as possible behavioural addiction. If this expansion does not end, both the relevance and the credibility of the field of addictive disorders might be questioned, which may prompt a dismissive appraisal of the new DSM-5 subcategory for behavioural addiction. We propose an operational definition of behavioural addiction together with a number of exclusion criteria, to avoid pathologizing common behaviours and provide a common ground for further research. The definition and its exclusion criteria are clarified and justified by illustrating how these address a number of theoretical and methodological shortcomings that result from existing conceptualizations. We invite other researchers to extend our definition under an Open Science Foundation framework.

[more ▼]Simulation of legal policies is an important decision-support tool in domains such as taxation. The primary goal of legal policy simulation is predicting how changes in the law affect measures of interest, e.g., revenue. Legal policy simulation is currently implemented using a combination of spreadsheets and software code. Such a direct implementation poses a validation challenge. In particular, legal experts often lack the necessary software background to review complex spreadsheets and code. Consequently, these experts currently have no reliable means to check the correctness of simulations against the requirements envisaged by the law. A further challenge is that representative data for simulation may be unavailable, thus necessitating a data generator. A hard-coded generator is difficult to build and validate. We develop a framework for legal policy simulation that is aimed at addressing the challenges above.

[more ▼]Public transcriptomics studies have shown that several genes display pronounced gender differences in their expression in the human brain, which may influence the manifestations and risk for neuronal disorders. Here we apply a transcriptome-wide analysis to discover genes with gender-specific expression and significant alterations in public post mortem brain tissue from Alzheimer’s disease (AD) patients compared to controls. We identify the sex-linked ubiquitin specific peptidase 9 (USP9) as an outstanding candidate gene with highly significant expression differences between the genders and male-specific under-expression in AD. Since previous studies have shown that USP9 can modulate the phosphorylation of the AD-associated protein MAPT, we investigate functional associations between USP9 and MAPT in further detail. After observing a high positive correlation between the expression of USP9 and MAPT in the public transcriptomics data, we show that USP9 knockdown results in significantly decreased MAPT expression in a DU145 cell culture model and a concentration-dependent decrease for the MAPT orthologs mapta and maptb in a zebrafish model. From the analysis of microarray and qRT-PCR experiments for the knockdown in DU145 cells and prior knowledge from the literature, we derive a data-congruent model for a USP9-dependent regulatory mechanism modulating MAPT expression via BACH1 and SMAD4. Overall, the analyses suggest USP9 may contribute to molecular gender differences observed in tauopathies and provide a new target for intervention strategies to modulate MAPT expression.

On the other hand, there exist also divergent series solutions of Schröder’s equation in this situation. We give some applications of our results to iterative functional equations, functional-differential equations and iteration groups.

This article draws upon growth intention to examine whether firm size growth is the channel through which growth intention influences sales revenue growth. Results from the analysis of a dataset of 20,472 French new ventures reveal that: (1) growth intention has a positive impact on sales revenue growth; (2) firm size growth has a positive impact on sales revenue growth; and (3) firm size growth mediates the effect of growth intention on sales revenue growth. These findings show that firm size growth is a means to achieve sales revenue growth and not only a finality per se.

[more ▼]Cross-site scripting and injection vulnerabilities are among the most common and serious security issues for Web applications. Although existing static analysis approaches can detect potential vulnerabilities in source code, they generate many false warnings and source-sink traces with irrelevant information, making their adoption impractical for security auditing. One suitable approach to support security auditing is to compute a program slice for each sink, which contains all the information required for security auditing. However, such slices are likely to contain a large amount of information that is irrelevant to security, thus raising scalability issues for security audits. In this paper, we propose an approach to assist security auditors by defining and experimenting with pruning techniques to reduce original program slices to what we refer to as security slices, which contain sound and precise information. To evaluate the proposed approach, we compared our security slices to the slices generated by a state-of-the-art program slicing tool, based on a number of open-source benchmarks. On average, our security slices are 76% smaller than the original slices. More importantly, with security slicing, one needs to audit approximately 1% of the total code to fix all the vulnerabilities, thus suggesting significant reduction in auditing costs.

[more ▼]Legitimacy is crucial for entrepreneurs. It is the cornerstone for creating relationships with stakeholders and mitigating resource constraints. But, other-referent legitimacy is also related to the cognitive image of individual legitimacy. Drawing on the identity-based model of legitimacy, we argue that personality traits (big five) and social capital (strong ties) of entrepreneurs impact self-perceived legitimacy of entrepreneurs. Based on survey data of 98 German private physicians, this paper examines antecedents of self-perceived legitimacy towards two main stakeholders: patients and peers. We find that high levels of agreeableness stimulate self-perceived legitimacy towards patients and peers, whereas openness to experience solely influences physicians’ self-perceived legitimacy towards patients. In addition, our results highlight the contingent effect of personality traits by underlining the role of strong ties as moderator of the relationship between personality traits and the self-perceived legitimacy. By identifying these configurations we contribute to the literature on entrepreneurship with a refined perspective of antecedents of self-perceived legitimacy. Moreover, we give recommendations on how private physicians can benefit from two personality traits – agreeableness and openness to experience – and how they can manage weak and strong ties in order to diffuse their reputation.

[more ▼]The structure signature of a system made up of n components having continuous and i.i.d. lifetimes was defined in the eighties by Samaniego as the n-tuple whose k-th coordinate is the probability that the k-th component failure causes the system to fail. More recently, a bivariate version of this concept was considered as follows. The joint structure signature of a pair of systems built on a common set of components having continuous and i.i.d. lifetimes is a square matrix of order n whose (k,l)-entry is the probability that the k-th failure causes the first system to fail and the l-th failure causes the second system to fail. This concept was successfully used to derive a signature-based decomposition of the joint reliability of the two systems. In the first part of this paper we provide an explicit formula to compute the joint structure signature of two or more systems and extend this formula to the general non-i.i.d. case, assuming only that the distribution of the component lifetimes has no ties. We also provide and discuss a necessary and sufficient condition on this distribution for the joint reliability of the systems to have a signature-based decomposition. In the second part of this paper we show how our results can be efficiently applied to the investigation of the reliability and signature of multistate systems made up of two-state components. The key observation is that the structure function of such a multistate system can always be additively decomposed into a sum of classical structure functions. Considering a multistate system then reduces to considering simultaneously several two-state systems.

[more ▼]Growth in scientific productivity over the 20th century resulted significantly from three major countries in European science—France, Germany, and the United Kingdom. We chart the development of universities and research institutes that bolster Europe’s key position in global science. We uncover both stable and dynamic patterns of productivity in the fields of STEM, including health, over the twentieth century. On-going internationalization of higher education and science has been accompanied by increasing competition and collaboration. Despite policy goals to foster innovation and expand research capacity, policies cannot fully account for the differential growth of scientific productivity we chart from 1975 to 2010. Our neoinstitutional framework facilitates explanation of differences in institutional settings, organizational forms, and organizations that produce the most European research. We measure growth of published peer-reviewed articles indexed in Thomson Reuters’ Science Citation Index Expanded (SCIE). Organizational forms vary in their contributions, with universities accounting for nearly half but rising in France; ultrastable in Germany at four-fifths, and growing at around two-thirds in the UK. Differing institutionalization pathways created the conditions necessary for continuous, but varying growth in scientific productivity in the European center of global science. The research university is central in all three countries, and we identify organizations leading in research output. Few analyses explicitly compare across time, space, and different levels of analysis. We show how important European science has been to overall global science productivity. In-depth comparisons, especially the organizational fields and forms in which science is produced, are crucial if policy is to support research and development.

[more ▼]This paper studies pension insecurity in a sample of non-retired individuals aged 50 years or older from 18 European countries. We capture pension insecurity with the subjective expectations on the probability that the government will reduce the pensions of the individual before retirement or will increase the statutory retirement age. We argue that changes in economic conditions and policy affect the formation of such probabilities, and through this, subjective wellbeing. In particular, we study the effects of pension insecurity on subjective wellbeing with pooled linear models, regressions per quintiles and instrumental variables. We find a statistically significant, stable and negative association between pension insecurity and subjective wellbeing. Our findings reveal that the individuals who are more affected by pension insecurity are those who are further away fromtheir retirement, have lower income, assess their life survival as low, have higher cognitive abilities and do not expect private pension payments.

[more ▼]We discuss a framework for quantizing a Poisson manifold via the quantization of its symplectic groupoid, that combines the tools of geometric quantization with the results of Renault's theory of groupoid C*-algebras. This setting allows very singular polarizations. In particular we consider the case when the modular function is "multiplicatively integrable", i.e. when the space of leaves of the polarization inherits a groupoid structure. If suitable regularity conditions are satisfied, then one can define the quantum algebra as the convolution algebra of the subgroupoid of leaves satisfying the Bohr-Sommerfeld conditions. We apply this procedure to the case of a family of Poisson structures on CP_n, seen as Poisson homogeneous spaces of the standard Poisson-Lie group SU(n+1). We show that a bihamiltoniam system on CP_n defines a multiplicative integrable model on the symplectic groupoid; we compute the Bohr-Sommerfeld groupoid and show that it satisfies the needed properties for applying Renault theory. We recover and extend Sheu's description of quantum homogeneous spaces as groupoid C*-algebras.

[more ▼]One of humanity’s most pressing problems is the inequality between people from “developed” and “developing” countries, which counteracts joint efforts to combat other large scale problems. Little is known about the psychological antecedents that affect the perception of and behavioral responses to global inequality. Based on, and extending, Duckitt’s (2001) dual-process model, the current research examines psychological antecedents that may explain how people in an industrialized Western country respond to global inequality. In two studies (N1 = 116, N2 = 117), we analyzed the relationship between the Big Five and justice constructs, right-wing authoritarianism (RWA), social dominance orientation (SDO), and behavioral intentions to reduce global inequality. Two-group path analysis revealed support for the dual-process model in that RWA and SDO were important predictors of behavioral intentions and partially acted as mediators between personality and such intentions. Moreover, justice sensitivity explained variance beyond the “classic” DPM variables. In Study 2, we additionally assessed individuals’ global social identification and perceived injustice of global inequality that explained additional variance. Extending previous work on the dual-process model, these findings demonstrate that individual and group-based processes predict people’s responses to global inequality and uncover potentials to promote behavior in the interest of global justice.

The use of diagnostic techniques enables the achievement of these requirements. This paper focuses on model-based fault detection and isolation (FDI) for PEM fuel cell stack systems. The work consists in designing and selecting a subset of consistency relations such that a set of predefined faults can be detected and isolated. Despite a nonlinear model of the PEM fuel cell stack system will be used, consistency relations that are easily implemented by a variable back substitution method will be selected. The paper also shows the significance of structural models to solve diagnosis issues in complex systems.

[more ▼]Due to unobtrusiveness and ease of implementation, viewing time (VT) measures of sexual interest in children have sparked increasing research interest in forensic contexts over the last two decades. The current study presents two meta-analyses of VT measures adapted to assess pedophilic interest to determine their discrimination between sexual offenders against children (SOC) and non-SOC groups as well as convergent validity (associations with other measures of sexual interest in children). On average, VT measures showed moderate discrimination between criterion groups (fixed-effect d = 0.60, 95% CI [0.51, 0.68], N = 2,705, k = 14) and significant convergent validity with self-reports, penile plethysmography, Implicit Association Tests and offence behavioral measures ranging from r =.18 to r = .38. VT measures, however, provided better discrimination for adults (fixed-effect d = 0.78, 95% CI [0.64, 0.92]) than adolescent samples (fixed-effect d = 0.50, 95% CI [0.40, 0.61]), Qbetween = 9.37, p = .002. Moreover, using pedophilic difference scores within adult samples substantially increased VT measures’ validity (fixed-effect d = 1.03, 95% CI [0.82, 1.25], N = 414, k = 7). Results are discussed in terms of their theoretical and applied implications for forensic contexts.

Quaipo, the 'heart of Manila', has responded to and negotiates with macroeconomic challenges through the underground economy of media piracy. Given the increase in population, unemployment and the general degradation of urban living amongst the poor, the economy of piracy has become a conduit of socio-economic changes that intersect with the culture-specific economy of worship. Quiapo is a fascinating terrain of Manilenos social history; it is the site of class tension, religious and ethnic divide, state intervention, and urban culture.

It reflexively analyses the entangled performances of knowledge and praxis around hygiene in the context of “international” open-air school conferences and in relation to “materials” of open-air education. Such performances reveal open-air schools as “practice and movement” unbound by “national” or otherwise imagined borders. Fragmentation accompanied their circulation and ensued from non/humans’ active, co-constitutive role in the mediation of knowledge and praxis. While underexplored, material and economic factors were key to this process. Their analysis enriches the study of the “internationalization” of school hygiene.

[more ▼]A new method is proposed for characterising local urban patterns at the scale of a large urban region. The approach overcomes the difficulties of surface-based representations of built-up morphologies and provides an efficient way to account for the proximity of built and non-built land. The strength of the approach resides in the direct use of the coordinates of each building, a very parsimonious input of external parameters, and a local spatial statistical perspective. The method consists in, first, constructing and clumping the Minimum Spanning Tree (MST) that links each building to its neighbours in order to obtain connected urban and suburban graph subsets, and second, measuring a Local Index of Spatial Association (LISA) on inter-building distances in order to characterise patterns. The method differentiates heterogeneous settlements from statistically significant homogeneous clusters with either long or short connections between buildings. The method is applied to the Southern periphery of Brussels (Belgium).

[more ▼]Whilst contributing to a person’s language, cognitive and personal development and whilst a common practice in the daily lives of bilinguals, translanguaging is rarely observed in educational institutions. The present paper examines the situations and the ways in which preschool children in trilingual Luxembourg translanguage during collaborative storytelling on iTEO, an iPad app which allows for the recording and editing of oral language. Currently 62.4% of children do not speak Luxembourgish on school entry. Language policies focus on the learning of Luxembourgish. This, the small class sizes and the absence of peers with similar language backgrounds may limit the opportunities for translanguaging. The present qualitative, longitudinal study takes a mixed-method approach. The findings show that the 5 focus children in preschool translanguaged frequently, in different ways and for a range of purposes, while drawing on features of several languages. The process of translanguaging depended on the individual child and on contextual factors. We argue that storytelling on iTEO opens up safe translanguaging spaces that contribute to inclusive multilingual pedagogies.

[more ▼]Background: Categorizing perceptual stimuli is a mechanism for facilitating the processing of sensory input from our environment. This facilitation of perception is achieved through generalization (assimilation) of stimulus characteristics within categories and accentuation between categories. These categorization processes have been demonstrated in visual, auditory, tactile and social perception, but never in pain perception. Method: We presented participants with six thermal noxious stimuli, increasing in steps of 0.5 °C. In an experimental group, stimuli were assigned to two categories labelled A and B containing the three lower (A1, A2, A3) and three higher (B1, B2, B3) stimuli. A control group did not receive such category information (stimuli were labelled S1–S6). In a first part of the experiment, participants simply rated pain intensity and unpleasantness for all stimuli. In a second part, we presented stimuli without labels and participants had to identify the label of each stimulus. Results: We found evidence for categorization effects in both pain ratings and stimulus identification data. In particular, unpleasantness ratings within categories were more similar to each other, and ratings between categories less similar, in the experimental compared to control group. Participants in the experimental group also confused stimuli more often within than between categories, and were more confident about category membership of stimuli at the category border, compared to participants in the control group. Conclusions: Mere category information, using abstract category labels, significantly changes pain perception. Implications for our understanding of cognitive pain modulation mechanisms, as well as clinical implications of categorization effects are discussed. Significance: Categorization effects in pain perception are demonstrated. Classifying and labelling painful events can modulate early perceptual processes, lead to under- or overestimation of pain symptoms and affect decision-making behaviour related to pain.

This On the Agenda demonstrates that this widespread pessimism is unjustified, since it is based on an exceedingly formalistic reading of the law. Secession (from States) and withdrawal (from international organisations) is always possible de facto: the relevant question is whether constitutional provisions ensure an orderly secession and discourage casual recourse thereto. Art. 50 TEU arguably constitutes a “well-designed secession clause”, since it ensures the EU’s unity in withdrawal negotiations, limits the discretion of the departing State regarding the activation and termination of the withdrawal procedure, and induces it to reach a compromise with the Union. Art. 50 thus ensures a fair balance between the concern for the EU’s integrity and the democratic and federal principles that inspire it.

[more ▼]We investigate n-ary semigroups as a natural generalization of binary semigroups. We refer it as a pair (X,F_n), where X is a set and an n-associative function F_n : X^n -> X is defined on X. We show that if F_n is idempotent, n-associative function which is monotone in each of its variables, defined on an interval I and has a neutral element, then F_n is combination of the minimum and maximum operation. Moreover we can characterize the n-ary semigroups (I,F_n) where F_n has the previous properties.

[more ▼]This paper addresses the problem of synchronizing orthogonal matrices over directed graphs. For synchronized transformations (or matrices), composite transformations over loops equal the identity. We formulate the synchronization problem as a least-squares optimization problem with nonlinear constraints. The synchronization problem appears as one of the key components in applications ranging from 3D-localization to image registration. The main contributions of this work can be summarized as the introduction of two novel algorithms; one for symmetric graphs and one for graphs that are possibly asymmetric. Under general conditions, the former has guaranteed convergence to the solution of a spectral relaxation to the synchronization problem. The latter is stable for small step sizes when the graph is quasi-strongly connected. The proposed methods are verified in numerical simulations.

[more ▼]This article examines national identity construal processes within the case study context of Luxembourg. Building on research highlighting the modalities of generalization from case studies, I present the country case that is Luxembourg. This social universe has a foreign population percentage of 47% and what is considered majority and minority becomes increasingly fluid. The migration process itself is fluid, ranging from daily migration, to medium-term stays, return visits and permanent immigration including uptake of citizenship. Within such a fluid environment, where national borders are permeable at the physical level of crossing borders and (national) societies are nested within societies, culture contact is a permanent feature in daily life. Nationality becomes a salient feature as culture contact tends to prompt reflection, resulting in questioning and (re-)negotiation of national identity. This affects the native population as well as the diverse immigrant population – with diversity going beyond the level of country of origin. Many individuals are also of mixed nationality and some examples for the construal process of national identity will be provided, illustrating how national identity is negotiated at individual level. Like a periscope, this country let s us adjust mirrors, permitting us to observe modes of identity construal which would otherwise be obstructed from the field of view. The case study that is Luxembourg allows us to look at the micro-setting of the construction, potentially of something new.

[more ▼]Basic motor competencies (in German: Motorische Basiskompetenzen; MOBAK) are motor performance dispositions formulated as minimum standards that empower children to participate in the culture of human movement. In opposition to movement-specific and process-oriented fundamental movement skills assessing the quality of movement execution, basic motor competencies are context-specific and product-oriented and focus on the mastery of minimum motor demands. Consequently, the promotion of basic motor competencies is a central goal of physical education, as they are essential prerequisites to be able to develop a physically active lifestyle. For the diagnosis of basic motor competencies, teachers need valid survey instruments that can help them to adapt their didactic-methodical action. For this purpose, a test battery for the assessment of the basic motor competencies of third graders was developed (MOBAK-3) and subjected to empirical validation (N = 399; 50.4% female; M = 8.45 years, SD = .52). The exploratory structural equation modeling indicates a structure with three factors named “Locomotion,” “Object-control” and “Moving in water”. This structure could be confirmed in the confirmatory factor analysis (CFI = .998; RMSEA = .009) [less ▲]Detailed reference viewed: 17 (1 UL)
