Attention plays a pivotal role in the experience of pain and its impact upon daily activities. Accordingly, research on the interplay between attention and pain has a long scientific history. Within this chapter, we discuss the theoretical frameworks that aim to explain the relationship between attention and pain. We argue for a motivational perspective on pain that highlights the critical role of cognitive, affective and contextual factors in explaining the interplay between attention and pain. To substantiate this argument, we provide an overview of available research addressing the bottom-up capture of attention by pain and the top-down modulation (both inhibition and facilitation) of attention for pain. We conclude this chapter with guidelines and suggestions for future research and discuss clinical implications of adopting a motivational perspective on pain. [less ▲]

Children’s development of verbal number skills (i.e, counting abilities and knowledge of the number names) presents a milestone in mathematical development. Different factors such as visuo-spatial and verbal abilities have been discussed to contribute to the development of these foundational skills. To understand the cognitive nature of verbal number skills in young children, the present study assessed the relation of preschoolers’ verbal and visuo-spatial abilities to their verbal number skills. In total, 141 children aged between five and six years participated in the present study. Verbal number skills were regressed on vocabulary, phonological awareness and visuo-spatial abilities, as well as verbal and visuo-spatial working memory in a structural equation model. Only visuo-spatial abilities emerged as a significant predictor of verbal number skills in the estimated model. Our results suggest that visuo-spatial abilities contribute to a larger extent to children’s verbal number skills than verbal abilities. From a theoretical point of view, these results suggest a visuo-spatial, rather than a verbal, grounding of verbal number skills. These results are potentially informative for the conception of early mathematics assessments and interventions. [less ▲]

Background and aims: Binge-watching (i.e., seeing multiple episodes of the same TV series in a row) now constitutes a widespread phenomenon. However, little is known about the psychological factors underlying this behavior, as reflected by the paucity of available studies, most merely focusing on its potential harmfulness by applying the classic criteria used for other addictive disorders without exploring the uniqueness of binge-watching. The present study thus aimed to take the opposite approach as a first step toward a genuine understanding of binge-watching behaviors through a qualitative analysis of the phenomenological characteristics of TV series watching. Methods: A focus group of regular TV series viewers (N=7) was established to explore a wide range of aspects related to TV series watching (e.g., motives, viewing practices, related behaviors). Results: A content analysis identified bingewatching features across three dimensions: TV series watching motivations, TV series watching engagement, and structural characteristics of TV shows. Most participants acknowledged that TV series watching can become addictive, but they all agreed having trouble recognizing themselves as truly being an “addict.” Although obvious connections could be established with substance addiction criteria and symptoms, such parallelism appeared to be insufficient, as several distinctive facets emerged (e.g., positive view, transient overinvolvement, context dependency, low everyday life impact). Discussion and conclusions: Research should go beyond the classic biomedical and psychological models of addictive behaviors to account for binge-watching in order to explore its specificities and generate first steps toward an adequate theoretical rationale for these emerging problematic behaviors.

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.

The integrative force of the Member States’ status on the judicial function is expressed through the loyalty obligation to provide remedies sufficient to ensure effective legal protection in the fields covered by Union law (Art 19, par 1, subpar 2, TEU). Member States have to ensure access to the national judge, who has been entrusted with a European mandate, and who is in measure to cooperate with the Court of Justice through the preliminary reference procedure. The Member States establish in this way an integrated judicial function. The exercise of such a function by the national judge, in cooperation with the Court of Justice and under the control of the Member State, implies integrative dynamic, which however depends on the balancing exercise with national procedural autonomy and the margin of appreciation of the national judge.

This article describes a research project that aimed to classify different types of sustainability-related school tasks in terms of two central approaches in primary school education: action-based and task-based learning. Using a textbook analysis approach, the article clarifies implicit and explicit forms of sustainability education in school tasks in Luxembourgish science textbooks for Grades 1 to 6. The study uses a two-step analysis: first, scanning textbooks on content relating to sustainability; and, second, evaluating the teaching practices associated with this content apparent in the textbooks. Step one identifies the school tasks in which sustainability content is implicitly or explicitly addressed while step two analyzes which forms of action-based and task-based learning occur in these sustainability-related school tasks. Based on the results two claims can be made: first, that there is very little sustainability-related content in Luxembourgish primary science textbooks, and those topics raised mostly relate to sustainability only indirectly; secondly, action-based and task-based learning are undervalued in the context of sustainability-related school tasks; neither of the two was commonly found in school tasks in sustainability education.

Executing an entire regression test suite after every code change is often costly in large software projects. To address this challenge, various regression test selection techniques have been proposed in the literature. One of those approaches is the Multi-Objective Regression Test Optimization (MORTO) approach, which is applied when there are multiple objectives during regression testing (e.g., minimizing the number of test cases and maximizing test coverage). This paper reports an action research type of study which was conducted to improve regression test-selection practices of a safety-critical industrial software in the defence domain based on the MORTO approach. The problem is formulated and solved by converting the multi-objective genetic-algorithm (GA) problem into a custom-built scalarized single-objective GA. The empirical results demonstrate that this approach yields a more efficient test suite (in terms of testing cost and benefits) compared to the old (manual) test-selection approach and another approach from the literature, i.e., the selective requirement coverage-based approach. Based on the context and need of the company, we developed the GA-based solution on a set of five cost objectives and four benefit objectives for regression testing while providing full coverage of the affected (changed) requirements. Since our proposed approach has been beneficial in the industrial context, it is currently in active use in the company. [less ▲]

Research evaluation systems in many countries aim to improve the quality of higher education. Among the first such systems, the UK's Research Assessment Exercise (RAE) from 1986 is now the Research Excellence Framework (REF). Highly-institutionalized, it holds research(ers) accountable. While studies describe the effects at different levels, this longitudinal analysis examines the gradual institutionalization and (un)intended consequences from 1986 to 2014. First, we analyze historically RAE/REF's rational, formalization, standardization, and transparency, framing it as a strong research evaluation system. Second, we locate the multidisciplinary field of education, analyzing submission behavior (staff, outputs, funding) of Departments of Education over time. We find: decreases in submitted staff; the research article as preferred publication format; the rise of quantitative analysis; and high and stable concentration of funding among few Departments. Policy instruments invoke varied responses, wit such reactivity shown by the increasing selectivity of submitted staff as a form of reverse engineering and the research article as the preferred output as a self-fulfilling prophecy. The funding concentration manifests an intended consequence, facilitating greater disparities between Departments of Education. These findings emphasize how research assessment impacts the structural organization and cognitive development of educational research in the UK. [less ▲]

To cost-effectively test embedded software, practitioners and researchers have proposed many test techniques, approaches, tools, and frameworks. However, obtaining an overview of the state of the art and state of the practice in this area is challenging for practitioners or new researchers. In addition, owing to an inadequate overview of what already exists in this area, some companies often reinvent the wheel by designing a test approach that’s new to them but already exists. To address these problems, the authors conducted a systematic literature review of this area that covered the testing topics, testing activities, test artifacts, and industries on which the studies focused. The results can benefit both practitioners and researchers by serving as an index to the vast body of knowledge in this important, fast-growing area. [less ▲]

Visual GUI testing (VGT) is a tool-driven technique, which uses image recognition for interaction and assertion of the behaviour of system under test. Motivated by a real industrial need, in the context of a large Turkish software and systems company providing solutions in the areas of defense and IT sector, we systematically planned and applied a VGT project in this industrial context. The goal of the initial phase of the project was to empirically evaluate two well-known VGT tools (Sikuli and JAutomate) to help the company select the best tool for a given testing project. Our results show that both two tools suffer from similar test ‘Replay’ problems such as the inability to find smaller-sized images. The repeatability of test executions was better for JAutomate in case of one of the two software under test (SUT) while it was comparable for the other. In terms of test development effort, for both tools, there were high correlations with number of steps in test suites, however the effort is reduced if test code is reused. The study has already provided benefits to the test engineers and managers in the company by increasing the know-how in the company w.r.t. VGT, and by identifying the challenges and their workarounds in using the tools. The industrial case study in this paper intends to add to the body of evidence in VGT and help other researchers and practitioners. [less ▲]

Bordered by Belgium, France, and Germany, Luxembourg is one of the three main seats of the European Union’s institutions. The Grand Duchy of Luxembourg sits at the crossroads between Europe’s Germanic and Francophone language communities. The country has experienced remarkable migratory flows, resulting in an ethnically hyper-diverse and multilingual population. Reflecting this cultural diversity, the educational system at all levels emphasizes language learning. Historically an agrarian society, a century ago it developed a very strong steelmaking industry and over the past decades has witnessed extraordinary growth in its financial services sector. Established to broaden the economic bases of the country, thus reducing overreliance on the steel and banking industries, yet against considerable pecuniary and ideological resistance, the national flagship University of Luxembourg (UL) was founded in 2003 upon initiative of a small group of elite decisionmakers. As a private, government-dependent institution (établissement public) directed by a Board of Governors (Conseil de Gouvernance), the university’s major funding is provided by the state, although its third-party funding has increased rapidly and substantially. Ironically, while spatial mobility is everywhere supported, Luxembourg has invested considerable capital and strategic planning in establishing its own national university. It aims to compete globally by concentrating its intellectual and financial resources and by building on the country’s strengths and priorities. The state took this ambitious step in scientific capacity-building in founding a research-oriented university, in so doing also providing a stay-at-home alternative for Luxembourg’s youth, traditionally educated abroad. The long-standing custom of educating elites in other countries was ostensibly justified by the establishment of cosmopolitan, Europe-wide networks. Today, rising international competition and supranational coordination have increased pressure on Luxembourg to grow its higher education system and thus also foster educational and scientific innovation. The University provides a means to diversify the economy and to integrate citizens from diverse cultural background, while the polity remains dominated by local elites. Oriented towards the Grand Duchy’s unique context—small size, but simultaneously flourishing center of European governance and international business—the University was founded upon the principles of internationality, multilingualism, and interdisciplinarity.

Need for Cognition (NFC) is increasingly being investigated in educational research. In contrast to other non-cognitive constructs in this area, such as academic self-concept and interest, NFC has consistently been conceptualized as domain-general. We employed structural equation modelling to address the question of whether NFC can be meaningfully and gainfully conceptualized as domain-specific. To this end, we developed a domain-specific 20-item NFC scale with parallel items for Science, Mathematics, German, and French. Additionally, domain-general NFC was assessed with five domain-general items. Using a cross-sectional sample of more than 4500 Luxembourgish 9th graders, we found that a nested-factor model incorporating both a general factor and domain-specific factors better accounted for the data than a single- factor or a correlated-factor model. However, the influence of the general factor was markedly stronger than in corresponding models for academic self-concept and interest. When controlling for the domain-specific factors, only Mathematics achievement was significantly predicted by the domain-general factor, while all achievement measures (Mathematics, French, and German) were predicted by the corresponding domain-specific factor. The nested domain-specific NFC factors were clearly empirically distinguishable from first-order domain-specific interest factors. [less ▲]

Motivated by a real-world industrial need in the context of a large IT solutions company based in Turkey, the authors and their colleagues developed and introduced automated test suites for GUI testing of two large-scale law-practice management software (comprising of 414 and 105 KLOC). We report in this paper our experience in developing and introducing a set of large automated test suites (more than 50 KLOC in total), using best practices in state-of-the art and –practice, and to report its observed benefits by conducting cost-benefit analysis in the specific industrial context. The project was conducted based on the principles of case-study and “action research” in which the real industrial needs drove the research. Among the best practices that we used are the followings: (1) the page-object test pattern, (2) modularity in test code, (3) creating test-specific libraries, and (4) using systematic guidelines to decide when and what (test cases) to automate. To assess the cost-benefit and Return On Investment (ROI) of test automation, we followed a hybrid measurement approach to assess both the quantitative and qualitative (intangible) benefits of test automation. The empirical findings showed that the automated GUI testing approach has indeed benefitted the test and QA team in the company under study and automation has been highly welcome by the test engineers. By serving as a success story and experience report in development and introduction of automated test suites in an industrial setting, this paper adds to the body of evidence in this area and it aims at sharing both technical (e.g., using automated test patterns) and process aspects (e.g., test process improvement) of our project with other practitioners and researchers with the hope of encouraging more industry-academia collaborations in test automation.
