How will the coronavirus disease 2019 (COVID-19) pandemic develop in the coming months and years? Based on an expert survey, we examine key aspects that are likely to influence the COVID-19 pandemic in Europe. The challenges and developments will strongly depend on the progress of national and global vaccination programs, the emergence and spread of variants of concern (VOCs), and public responses to non-pharmaceutical interventions (NPIs). In the short term, many people remain unvaccinated, VOCs continue to emerge and spread, and mobility and population mixing are expected to increase. Therefore, lifting restrictions too much and too early risk another damaging wave. This challenge remains despite the reduced opportunities for transmission given vaccination progress and reduced indoor mixing in summer 2021. In autumn 2021, increased indoor activity might accelerate the spread again, whilst a necessary reintroduction of NPIs might be too slow. The incidence may strongly rise again, possibly filling intensive care units, if vaccination levels are not high enough. A moderate, adaptive level of NPIs will thus remain necessary. These epidemiological aspects combined with economic, social, and health-related consequences provide a more holistic perspective on the future of the COVID-19 pandemic. [less ▲]

Propositional Typicality Logic (PTL) is a recently proposed logic, ob- tained by enriching classical propositional logic with a typicality opera- tor capturing the most typical (alias normal or conventional) situations in which a given sentence holds. The semantics of PTL is in terms of ranked models as studied in the well-known KLM approach to preferen- tial reasoning and therefore KLM-style rational consequence relations can be embedded in PTL. In spite of the non-monotonic features introduced by the semantics adopted for the typicality operator, the obvious Tarskian definition of entailment for PTL remains monotonic and is therefore not appropriate in many contexts. Our first important result is an impossibil- ity theorem showing that a set of proposed postulates that at first all seem appropriate for a notion of entailment with regard to typicality cannot be satisfied simultaneously. Closer inspection reveals that this result is best interpreted as an argument for advocating the development of more than one type of PTL entailment. In the spirit of this interpretation, we in- vestigate three different (semantic) versions of entailment for PTL, each one based on the definition of rational closure as introduced by Lehmann and Magidor for KLM-style conditionals, and constructed using different notions of minimality.

We study the limits of dynamic electoral accountability when voters are uncertain about politicians’ characteristics (adverse selection) and their actions (moral hazard). Existing work argues that voters cannot achieve their first-best payoff. This is attributed to inherent deficiencies of the electoral contract, including voters’ inability to pre-commit, and the restriction to a binary retention-replacement decision. We provide conditions under which, despite these constraints, voters can obtain arbitrarily close to the first-best payoff in an equilibrium of the electoral interaction. Our paper resolves that there need not be a trade-off between selection and control. [less ▲]

We analyse a measure of loneliness from a representative sample of German individuals interviewed in both 2017 and at the beginning of the COVID-19 pandemic in 2020. Both men and women felt lonelier during the COVID-19 pandemic than they did in 2017. The pandemic more than doubled the gender loneliness gap: women were lonelier than men in 2017, and the 2017-2020 rise in loneliness was far larger for women. This rise is mirrored in life-satisfaction scores. Men’s life satisfaction changed only little between 2017 and 2020; yet that of women fell dramatically, and sufficiently so to produce a female penalty in life satisfaction. We estimate that almost all of this female penalty is explained by the disproportionate rise in loneliness for women during the COVID-19 pandemic. [less ▲]

ABSTRACT This study sheds light on agency conflicts between creditors and shareholders and their effect on a firm's corporate social responsibility (CSR) performance. We find that the presence of institutional investors which simultaneously hold debt and equity claims in the same firm, so-called dual holders, leads to an increase in CSR performance by the firm that is dual-held (the dual holding firm). Using institutional mergers between separate lenders and equity holders as a natural experiment involving the shareholder-creditor conflict, we find that firms which exhibit dual ownership for the first time increase their CSR activities to a greater extent than a matched control group. In line with the previous literature, we interpret our findings as evidence that dual holders internalise agency conflicts. Thus, we find that a reduction in agency conflicts between creditors and shareholders, partly achieved by dual holders, positively affects the CSR activities of dual holdings. [less ▲]

This study examines how coal companies were affected by the announcement of thermal coal divestment made by Blackrock, a large institutional asset manager. Following the announcement, the largest thermal coal mining companies exhibited negative abnormal returns. However, the stock prices of other firms were not affected. Blackrock’s own share price increased following the announcement. We provide additional evidence that Blackrock protected its clients by lowering its exposure towards affected companies before the announcement. Overall, our results show that divestment has significant impacts on the companies in question and that the capital market sees divestment as value-enhancing for the divesting institution. [less ▲]

In this paper, we introduce the concept of ‘societal emotional environment’: the emotional climate of a society (operationalized as the degree to which positive and negative emotions are expressed in a society). Using data collected from 12,888 participants across 49 countries, we show how societal emotional environments vary across countries and cultural clusters, and we consider the potential importance of these differences for well-being. Multilevel analyses supported a ‘double-edged sword’ model of negative emotion expression, where expression of negative emotions predicted higher life satisfaction for the expresser but lower life satisfaction for society. In contrast, partial support was found for higher societal life satisfaction in positive societal emotional environments. Our study highlights the potential utility and importance of distinguishing between positive and negative emotion expression, and adopting both individual and societal perspectives in well-being research. Individual pathways to happiness may not necessarily promote the happiness of others. [less ▲]

When Deep Neural Networks (DNNs) are used in safety-critical systems, engineers should determine the safety risks associated with failures (i.e., erroneous outputs) observed during testing. For DNNs processing images, engineers visually inspect all failure-inducing images to determine common characteristics among them. Such characteristics correspond to hazard-triggering events (e.g., low illumination) that are essential inputs for safety analysis. Though informative, such activity is expensive and error-prone. To support such safety analysis practices, we propose SEDE, a technique that generates readable descriptions for commonalities in failure-inducing, real-world images and improves the DNN through effective retraining. SEDE leverages the availability of simulators, which are commonly used for cyber-physical systems. It relies on genetic algorithms to drive simulators towards the generation of images that are similar to failure-inducing, real-world images in the test set; it then employs rule learning algorithms to derive expressions that capture commonalities in terms of simulator parameter values. The derived expressions are then used to generate additional images to retrain and improve the DNN. With DNNs performing in-car sensing tasks, SEDE successfully characterized hazard-triggering events leading to a DNN accuracy drop. Also, SEDE enabled retraining leading to significant improvements in DNN accuracy, up to 18 percentage points. [less ▲]

Correctness of UML class diagrams annotated with OCL constraints can be checked using bounded verification techniques, e.g., SAT or constraint programming (CP) solvers. Bounded verification detects faults efficiently but, on the other hand, the absence of faults does not guarantee a correct behavior outside the bounded domain. Hence, choosing suitable bounds is a non-trivial process as there is a trade-off between the verification time (faster for smaller domains) and the confidence in the result (better for larger domains). Unfortunately, bounded verification tools provide little support in the bound selection process. In this paper, we present a technique that can be used to (i) automatically infer verification bounds whenever possible, (ii) tighten a set of bounds proposed by the user and (iii) guide the user in the bound selection process. This approach may increase the usability of UML/OCL bounded verification tools and improve the efficiency of the verification process. [less ▲]

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. [less ▲]

This paper examines whether the loan strategy of a microfinance institution is shaped by the entry of a bank. Specifically, we investigate whether the distance between a borrower of a microfinance institution and the closest bank influences loan conditions provided by the microfinance institution. We use an original panel dataset of 32,374 loans granted to 14,834 borrowers provided by one of the largest microfinance institutions in Madagascar between 2008 and 2014. We find that the closer a bank is located to a given MFI borrower, the larger the loan obtained and the less collateral required. We also find that the effect is stronger for clients that could be more easily caught by banks (i.e., large firms and clients without a previous relationship with the MFI). [less ▲]

We focus on the realistic maximization of the up-link minimum-signal-to-interference-plus-noise ratio (SINR) of a general multiple-input-single-output (MISO) system assisted by an intelligent reflecting surface (IRS) in the large system limit accounting for HIs. In particular, we introduce the HIs at both the IRS (IRS-HIs) and the transceiver HIs (AT-HIs), usually neglected despite their inevitable impact. Specifically, the deterministic equivalent analysis enables the derivation of the asymptotic weighted maximum-minimum SINR with HIs by jointly optimizing the HIs-aware receiver, the transmit power, and the reflect beamforming matrix (RBM). Notably, we obtain the optimal power allocation and reflect beamforming matrix with low overhead instead of their frequent necessary computation in conventional MIMO systems based on the instantaneous channel information. Monte Carlo simulations verify the analytical results which show the insightful interplay among the key parameters and the degradation of the performance due to HIs. [less ▲]

Attentional biases have been posited as one of the key mechanisms underlying the development and maintenance of chronic pain and co-occurring internalizing mental health symptoms. Despite this theoretical prominence, a comprehensive understanding of the nature of biased attentional processing in chronic pain and its relationship to theorized antecedents and clinical outcomes is lacking, particularly in youth. This study used eye-tracking to assess attentional bias for painful facial expressions and its relationship to theorized antecedents of chronic pain and clinical outcomes. Youth with chronic pain (n = 125) and without chronic pain (n = 52) viewed face images of varying levels of pain expressiveness while their eye gaze was tracked and recorded. At baseline, youth completed questionnaires to assess pain characteristics, theorized antecedents (pain catastrophizing, fear of pain, and anxiety sensitivity), and clinical outcomes (pain intensity, interference, anxiety, depression, and posttraumatic stress). For youth with chronic pain, clinical outcomes were reassessed at 3 months to assess for relationships with attentional bias while controlling for baseline symptoms. In both groups, youth exhibited an attentional bias for painful facial expressions. For youth with chronic pain, attentional bias was not significantly associated with theorized antecedents or clinical outcomes at baseline or 3-month follow-up. These findings call into question the posited relationships between attentional bias and clinical outcomes. Additional studies using more comprehensive and contextual paradigms for the assessment of attentional bias are required to clarify the ways in which such biases may manifest and relate to clinical outcomes.

On-board embedded software developed for spaceflight systems (space software) must adhere to stringent software quality assurance procedures. For example, verification and validation activities are typically performed and assessed by third party organizations. To further minimize the risk of human mistakes, space agencies, such as the European Space Agency (ESA), are looking for automated solutions for the assessment of software testing activities, which play a crucial role in this context. Though space software is our focus here, it should be noted that such software shares the above considerations, to a large extent, with embedded software in many other types of cyber-physical systems. Over the years, mutation analysis has shown to be a promising solution for the automated assessment of test suites; it consists of measuring the quality of a test suite in terms of the percentage of injected faults leading to a test failure. A number of optimization techniques, addressing scalability and accuracy problems, have been proposed to facilitate the industrial adoption of mutation analysis. However, to date, two major problems prevent space agencies from enforcing mutation analysis in space software development. First, there is uncertainty regarding the feasibility of applying mutation analysis optimization techniques in their context. Second, most of the existing techniques either can break the real-time requirements common in embedded software or cannot be applied when the software is tested in Software Validation Facilities, including CPU emulators and sensor simulators. In this paper, we enhance mutation analysis optimization techniques to enable their applicability to embedded software and propose a pipeline that successfully integrates them to address scalability and accuracy issues in this context, as described above. Further, we report on the largest study involving embedded software systems in the mutation analysis literature. Our research is part of a research project funded by ESA ESTEC involving private companies (GomSpace Luxembourg and LuxSpace) in the space sector. These industry partners provided the case studies reported in this paper; they include an on-board software system managing a microsatellite currently on-orbit, a set of libraries used in deployed cubesats, and a mathematical library certified by ESA.

We consider the solution of a multivariate stochastic differential equation with Levy-type jumps and with unique invariant probability measure with density μ. We assume that a continuous record of observations is available. In the case without jumps, Reiss and Dalalyan [7] and Strauch [24] have found convergence rates of invariant density estimators, under respectively isotropic and anisotropic H ̈older smoothness constraints, which are considerably faster than those known from standard multivariate density estimation. We extend the previous works by obtaining, in presence of jumps, some estimators which have the same convergence rates they had in the case without jumps for d ≥ 2 and a rate which depends on the degree of the jumps in the one-dimensional setting. We propose moreover a data driven bandwidth selection procedure based on the Goldenshluger and Lepski method [11] which leads us to an adaptive non-parametric kernel estimator of the stationary density μ of the jump diffusion X.

Cyber-physical systems (CPSs) typically consist of a wide set of integrated, heterogeneous components; consequently, most of their critical failures relate to the interoperability of such components. Unfortunately, most CPS test automation techniques are preliminary and industry still heavily relies on manual testing. With potentially incomplete, manually-generated test suites, it is of paramount importance to assess their quality. Though mutation analysis has demonstrated to be an effective means to assess test suite quality in some specific contexts, we lack approaches for CPSs. Indeed, existing approaches do not target interoperability problems and cannot be executed in the presence of black-box or simulated components, a typical situation with CPSs. In this paper, we introduce data-driven mutation analysis, an approach that consists in assessing test suite quality by verifying if it detects interoperability faults simulated by mutating the data exchanged by software components. To this end, we describe a data-driven mutation analysis technique (DaMAT) that automatically alters the data exchanged through data buffers. Our technique is driven by fault models in tabular form where engineers specify how to mutate data items by selecting and configuring a set of mutation operators. We have evaluated DaMAT with CPSs in the space domain; specifically, the test suites for the software systems of a microsatellite and nanosatellites launched on orbit last year. Our results show that the approach effectively detects test suite shortcomings, is not affected by equivalent and redundant mutants, and entails acceptable costs. [less ▲]

Sufficient conditions are provided to guarantee finite-time convergence and boundedness of the solutions.

This contribution frames the notions of inclusion and mental health by describing trends in European societies at the social and economic level that will have direct consequences for a participative civil society and social cohesion. Starting point is the observation that the world faces challenges at the start of the 21st century that are new and unprecedented in its history. The four global forces that break all the trends known so far in human history include urbanization, accelerating technological development, greater global connections, and population ageing. The authors first describe the scale of population ageing, as ageing populations characterize several developed economies. In a second step, they highlight some consequences of population ageing for social welfare and in a third part they elaborate on the notion of justice and inclusion in rapidly changing societies.

Economic insecurity has attracted growing attention, but there is no consensus as to its definition. We characterize a class of individual economic-insecurity measures based on the time profile of economic resources. We apply this economic-insecurity measure to political-preference data in the USA, UK, and Germany. Conditional on current economic resources, economic insecurity is associated with both greater political participation (support for a party or the intention to vote) and more support for conservative parties. In particular, economic insecurity predicts greater support for both Donald Trump before the 2016 US Presidential election and the UK leaving the European Union in the 2016 Brexit referendum.

This paper explores the interface between central banks and cryptocurrencies. Focusing on the European Central Bank (ECB), it identifies the potential threats that the rise of cryptocurrencies would pose to the basic and ancillary tasks of the ECB, in particular, its monetary policy operations and the exercise of its supervisory functions over credit institutions and payment systems. The paper finds that cryptocurrencies can potentially have both direct – through their potential impact on the price stability and monetary policy, and central banks’ monopoly over issuing base money – and indirect effects on central banks, mainly through the institutions and systems that fall under the ECB’s scope of competence. To address the challenges posed by cryptocurrencies, the ECB may take both legal (including supervisory and oversight) measures and non-legal (or technical) measures. With respect to technical measures, the ECB - to the extent falling within the scope of its competence - may focus on improving the efficiency of existing payment systems and addressing the existing frictions in market infrastructures to indirectly affect the cryptocurrency markets. Alternatively, it can venture into issuing Central Bank Digital Currency (CBDC). Regarding legal measures, central banks could envisage regulating cryptocurrencies either directly or indirectly. However, as the most significant potential impact of cryptocurrencies on central banks is likely to be indirect through the impact of cryptocurrencies on the banking and payment systems, and given the limitations on the ECB’s mandate and its regulatory and supervisory tools, it is apposite for the ECB to consider using indirect strategies and tools to influence cryptocurrency markets. This indirect approach can be implemented through the ECB’s existing supervisory and oversight powers over the banking and payment systems. This paper specifies the direct and indirect measures and assesses their merits in addressing the concerns about cryptocurrencies. [less ▲]

VANET safety applications broadcast cooperative awareness messages (CAM) periodically to provide vehicles with continuous updates about the surrounding traffic. The periodicity and the spatiotemporal information contained in these messages allow a global adversary to track vehicle movements. Many privacy schemes have been proposed for VANET, but only few schemes consider their impact on safety applications. Also, each scheme is evaluated using inconsistent metrics and unrealistic vehicle traces, which makes comparing the actual performance of different schemes in the wild more difficult. In this paper, we aim to fill this gap and compare different privacy schemes not only in terms of the privacy gained but also their impact on safety applications. A distortion-based privacy metric is initially proposed and compared with other popular privacy metrics showing its effectiveness in measuring privacy. A practical safety metric which is based on Monte Carlo analysis is then proposed to measure the QoS of two safety applications: forward collision warning and lane change warning. Using realistic vehicle traces, six state-of-the-art VANET privacy schemes are evaluated and compared in terms of the proposed privacy and safety metrics. Among the evaluated schemes, it was found that the coordinated silent period scheme achieves the best privacy and QoS levels but fully synchronized silence among all vehicles is a practical challenge. The CAPS and CADS schemes provide a practical compromise between privacy and safety since they employ only the necessary silence periods to prevent tracking and avoid changing pseudonyms in trivial situations.

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.

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. [less ▲]

This article develops a histoire croisée of health education using the example of open-air schools. 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. [less ▲]

This study examines the impacts of consumer confidence on stockpiling behavior and, subsequently, retail inventory management. We show how stockpiling behavior evolved during the “Great Recession” of 2008-2009 as consumer confidence waned and demonstrate the impact of this development on inventory management. Drawing on the two-segment household inventory theory consisting of non-stockpiling and stockpiling segments, we use a panel dataset (2005-2015) to calibrate household inventory holdings. This dataset then serves as input for a retailer-level case study. Our empirical analysis reveals significant impacts from changing stockpiling behavior. When consumer confidence is low, both stockpiling and non-stockpiling segments respond by reducing weekly consumption rates; however, the stockpiling segment also significantly lengthens the time between shopping trips, and ultimately increases the duration of inventory holdings. These changes to consumption and stockpiling add complexity to inventory planning, requiring retailers to carefully adjust inventory levels to maintain service levels. [less ▲]

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.

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. [less ▲]

Long-term behaviour of concrete structural elements is very important for evaluation of its health and serviceability range. The phenomena that must be considered are complex and lead to coupled multiphysics formulations. Such formulations are difficult not only from physical perspective, but also from computational perspective. In this contribution attention to computational efficiency and effective implementation is payed. Presented model for concrete ageing is based on microprestress-solidification (MPS) theory of Bazant [1], Kunzel’s model for heat and moisture transport [2] and Mazars model for damage [3]. Ageing linear viscoelastic response, which is immanent to MPS theory and concrete creep, leads to ordinary differetial equation for internal variables solved for every quadrature/nodal point. Numerical structure of the finite element discretisation is examined. Few simplifications on physical model lead to a very efficient linear algebra problem for which standard preconditioned Krylov solvers are reviewed. In parallel, weak and strong scaling tests are performed. All results are produced within open-source finite element framework FEniCS [4]. These models are usually a basis for more involved thermo-hygro-chemo-mechanical (THCM) models with migrating chemical species. It is anticipated, that presented results will help practitioners or other structural engineerers with the choice of suitable and efficient methods for long-term concrete modeling. [less ▲]

Our contribution here is to define a polynomial time subsumption procedure for nominal safe $ELO_{\bot}$ under RC that relies entirely on a series of classical, monotonic $EL_{\bot}$ subsumption tests. Therefore, any existing classical monotonic $EL_{\bot}$ reasoner can be used as a black box to implement our method.

Female comparative disadvantage refers to the mismatch of the female with respect to achievements in different dimensions of human well-being in comparison with the corresponding achievements of the male. This paper axiomatically derives a general family of female comparative disadvantage indicators which has very important policy implications. The axioms employed are shown to be ‘independent’. An empirical illustration of the general index is provided using the UNDP data on mean years of schooling, life expectancy at birth and gross national income per capita in 2018. Results show that female comparative disadvantage is not necessarily related to standard measures of human development, such as the HDI, and is present even in countries reaching very high human development. The factor where policy intervention is needed the most is income. [less ▲]

Regional foreign banks expanded quickly over the past decade in developing and emerging countries and have a growing influence in banking systems. We question whether the development of African regional foreign banks, also called Pan-African banks, influences financial inclusion of firms and households. To this end, we combine the World Bank Global Findex database and the World Bank Enterprise Surveys with a hand-collected database on the presence of regional foreign banks. We find that Pan-African banks presence increases firms’ access to credit and limited evidence that they favor financial access of the middle class by restoring confidence in banks. We suggest that this impact is related to the adoption of an aggressive strategy aiming at gaining market shares rather than through the exploitation of informational and technological advantages.

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. [less ▲]

We then prove that, for any such orbifold, its Chen-Ruan orbifold cohomology ring is isomorphic to the usual cohomology ring of any crepant resolution of its coarse moduli space. By vanishing of the quantum corrections, we show that this result fits in with Ruan's Cohomological Crepant Resolution Conjecture. [less ▲]

We present a Nitche’s method to couple non-conforming two and three-dimensional NURBS (Non Uniform Rational B-splines) patches in the context of isogeometric analysis (IGA). We present results for linear elastostatics in two and and three-dimensions. The method can deal with surface-surface or volume-volume coupling, and we show how it can be used to handle heterogeneities such as inclusions. We also present preliminary results on modal analysis. This simple coupling method has the potential to increase the applicability of NURBS-based isogeometric analysis for practical applications. [less ▲]

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.

We study Schröder’s equation (i.e. the problem of linearization) for local analytic functions F with F (0)=0, F(0)=1, F(0) a root of 1. While Schröder’s equation in this case need not have even a formal solution, we show that if F is formally linearizable, then it can also be linearized by an invertible local analytic transformation. 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. [less ▲]

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.

For many models of solids, we frequently assume that the material parameters do not vary in space, nor that they vary from one product realization to another. If the length scale of the application approaches the length scale of the micro-structure however, spatially fluctuating parameter fi elds (which vary from one realization of the fi eld to another) can be incorporated to make the model capture the stochasticity of the underlying micro-structure. Randomly fluctuating parameter fields are often described as Gaussian fields. Gaussian fi elds however assume that the probability density function of a material parameter at a given location is a univariate Gaussian distribution. This entails for instance that negative parameter values can be realized, whereas most material parameters have physical bounds (e.g. the Young's modulus cannot be negative). In this contribution, randomly fluctuating parameter fi elds are therefore described using the copula theorem and Gaussian fi elds, which allow di fferent types of univariate marginal distributions to be incorporated, but with the same correlation structure as Gaussian fields. It is convenient to keep the Gaussian correlation structure, as it allows us to draw samples from Gaussian fi elds and transform them into the new random fields. The bene fit of this approach is that any type of univariate marginal distribution can be incorporated. If the selected univariate marginal distribution has bounds, unphysical material parameter values will never be realized. We then use Bayesian inference to identify the distribution parameters (which govern the random fi eld). Bayesian inference regards the parameters that are to be identi fied as random variables and requires a user-defi ned prior distribution of the parameters to which the observations are inferred. For the homogenized Young's modulus of a columnar polycrystalline material of interest in this study, the results show that with a relatively wide prior (i.e. a prior distribution without strong assumptions), a single specimen is su ciffient to accurately recover the distribution parameter values.

Replication studies are important for the empirical research process. Yet, while there is an increased awareness of the need for replication in management research, it appears that such studies are rarely published in leading management journals. Importantly, we lack a comprehensive overview of replication studies in the top management journals that spans all sub-disciplines. Our systematic review closes this gap and provides an overview of the prevalence, types, outcomes, and impact of replication studies in management journals. We find that differences in the prevalence of replications between sub-disciplines exist and that most replications are wide replications. With regard to the replication outcome, our review shows that the share of non-confirming replications is low. Moreover, such replications are cited less often than confirming replications pointing towards a confirmation bias in management research. We discuss the implications of our results for authors, reviewers, and editors of management journals. [less ▲]

One of the problems perceived to be at the heart of the global financial crisis was an amalgamation of various commercial and investment banking activities under one entity, as well as the interconnectedness of the banking entities with other financial institutions, investment funds, and the shadow banking system. This paper focuses on various measures that aim to structurally separate the banking entities and their core functions from riskier financial activities such as (proprietary) trading or investments in alternative investment funds. Although banking structural reforms in the EU, UK, and the US have taken different forms, their common denominator is the separation of core banking functions from certain trading or securities market activities. Having reviewed the arguments for and against banking structural reforms and their varieties in major jurisdictions, including the EU, UK, US, France, and Germany, the paper argues that a more nuanced approach to introducing such measures at the EU level is warranted. Given the different market structures across the Atlantic and the lack of conclusive evidence on the beneficial impact of banking structural reforms, the paper concludes that the withdrawal of the banking structural reforms proposal by the European Commission has been a prudent move. It seems that in the absence of concrete evidence, experimenting with structural reforms at the Member-State level would be less costly and would provide for opportunities for learning from smaller mistakes that could pave the way for a more optimal approach to introducing banking structural reforms at the European level in the future.

Manila, like most cities in the developing world, is experiencing the effects of the flexibility of global capital and the consequences of being excluded from the flows of knowledge and finance. 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. Today, piracy and worship are forces by which the district's inhabitants and pilgrims define their lives and their labour. This essay examines how piracy and worship impact on the labour, space and gender dynamics of Quiapo. [less ▲]

The convergence of mobile edge computing (MEC) and blockchain is transforming the current computing services in wireless Internet-of-Things networks, by enabling task offloading with security enhancement based on blockchain mining. Yet the existing approaches for these enabling technologies are isolated, providing only tailored solutions for specific services and scenarios. To fill this gap, we propose a novel cooperative task offloading and blockchain mining (TOBM) scheme for a blockchain-based MEC system, where each edge device not only handles computation tasks but also deals with block mining for improving system utility. To address the latency issues caused by the blockchain operation in MEC, we develop a new Proof-of-Reputation consensus mechanism based on a lightweight block verification strategy. To accommodate the highly dynamic environment and high-dimensional system state space, we apply a novel distributed deep reinforcement learning-based approach by using a multi-agent deep deterministic policy gradient algorithm. Experimental results demonstrate the superior performance of the proposed TOBM scheme in terms of enhanced system reward, improved offloading utility with lower blockchain mining latency, and better system utility, compared to the existing cooperative and non-cooperative schemes. The paper concludes with key technical challenges and possible directions for future blockchain-based MEC research. [less ▲]

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.

The rise of early retirement in Europe is typically attributed to the European system of taxes and transfers. A model with an imperfectly competitive labor market allows us to consider also the effects of bargaining power and of matching efficiency on pre-retirement. We find that lower bargaining power of workers and declining matching efficiency have been important determinants of early retirement in France and Germany. These structural changes, combined with early-retirement transfers and population aging, are also consistent with the employment and unemployment rates, labor share and seniority premia. [less ▲]

Efficient and reliable operation of Polymer Electrolyte Membrane (PEM) fuel cells are key requirements for their successful commercialization and application. 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. [less ▲]

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 in 1910. The article starts out by presenting an overview of the community. Concentrated in Seoul and Chemulp’o, the Anglo-Saxon element dominated a community made up of diplomats, foreign experts in the service of the Korean government, merchants and missionaries. Next, the article describes two key characteristics of the European and American residents in Korea. Firstly, they were individuals defining themselves as bourgeois, or middle-class; secondly, the term “translocality” serves to bring together the multiple layers of border-crossing these individuals were involved in – as long-distance migrants between Europe or Northern America and East Asia, as migrants within the East Asian context, and as representatives of different Euro-American nationalities living together in Korea.

Statistical methods to test for effects of SNPs on exon inclusion exist, but often rely on testing of associations between multiple exon-SNP pairs, with sometimes subsequent summarization of results at the gene level. Such approaches require heavy multiple testing correction, and detect mostly events with large effect sizes. We propose here a test to find spliceQTL effects which takes all exons and all SNPs into account simultaneously. For any chosen gene, this score-based test looks for association between the set of exon expressions and the set of SNPs, via a random-effects model framework. It is efficient to compute, and can be used if the number of SNPs is larger than the number of samples. In addition, the test is powerful to detect effects that are relatively small for individual exon-SNP pairs, but are observed for many pairs. Furthermore, test results are more often replicated across datasets than pairwise testing results. This partly our test is more robust to exon-SNP pair-specific effects, but do not extend to multiple pairs within the same gene. We conclude that the test we propose here offers more power and better replicability in the search for spliceQTL effects. [less ▲]
