Charting significant growth in scientific productivity over the 20th century in four EU member states, this neo-institutional analysis describes the development and current state of universities and research institutes that bolsters Europe’s position as a key region in global science. On-going internationalization and Europeanization of higher education and science has been accompanied by increasing competition as well as collaboration. 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.

Social inequalities in dementia can be found in diagnosis, cure, care, and research. Less advantaged groups are women, persons with ethnic minority status, lower income, lower education, and living in more deprived or rural areas. These social inequalities suggest that funding of research and medical and care expenses related to dementia may not be equitably allocated to those in need, even in the most advanced countries. Experience from the field of heart disease gives an estimate on the timescale and efforts it takes to successfully address social inequalities related to gender. Strong concerted efforts will be needed as well to mitigate social inequalities in dementia. [less ▲]

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. [less ▲]

Objective: Huntington’s disease (HD) is characterized by motor and cognitive impairments including memory, executive, and attentional functions. However, because earlier studies relied on multidetermined attentional tasks, uncertainty still abounds regarding the differential deficit across attentional subcomponents. Likewise, the evolution of these deficits during the successive stages of HD remains unclear. The present study simultaneously explored 3 distinct networks of attention (alerting, orienting, executive conflict) in preclinical and clinical HD. Method: Thirty-eight HD patients (18 preclinical) and 38 matched healthy controls completed the attention network test, an integrated and theoretically grounded task assessing the integrity of 3 attentional networks. Results: Preclinical HD was not characterized by any attentional deficit compared to controls. Conversely, clinical HD was associated with a differential deficit across the 3 attentional networks under investigation, showing preserved performance for alerting and orienting networks but massive and specific impairment for the executive conflict network. This indexes an impaired use of executive control to resolve the conflict between task-relevant stimuli and interfering task-irrelevant ones. Conclusion: Clinical HD does not lead to a global attentional deficit but rather to a specific impairment for the executive control of attention. Moreover, the absence of attentional deficits in preclinical HD suggests that these deficits are absent at the initial stages of the disease. In view of their impact on everyday life, attentional deficits should be considered in clinical contexts. Therapeutic programs improving the executive control of attention by neuropsychology and neuromodulation should be promoted. [less ▲]

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.

Emotional ambivalence of adult children of care-dependent older parents is analyzed from the perspective of cognitive-motivational theories of emotion. Emotional ambivalence is conceived of as the co-presence of positive and negative emotions toward the multifaceted care situation involving these major elements: Multiple problems of the elderly parent, multiple caregiving tasks of the adult child, and multiple gains and losses for the elderly parent and for the adult child. In line with cognitive-motivational theories, positive and negative emotions are thought of as arising from mental comparisons between what adult children desire and what they believe with respect to the various facets of the care situation. Perceived fulfillment of such desires is assumed to lead to positive emotions (happiness, hope, moral pride, etc.) and perceived frustration to result in negative emotions (pity, fear, guilt, etc.) related to the elderly parent, oneself, or other family members. Because adult children usually have multiple desires (e.g., own welfare, welfare of older parent, welfare of other family members) which may be perceived as fulfilled in some areas and unfulfilled in others, various combinations of positive and negative emotions and thus emotional ambivalence is assumed to arise toward various aspects of the care situation. An illustrative application of this theoretical approach is given to a major care-related event, namely, the transition of an elderly parent to a nursing home. In conclusion, benefits for research and practice in the field of elder care (measurement, description, understanding, management, and positive functions of emotional ambivalence) are discussed.

This paper reports on inter-disciplinary research designed to investigate the stress-buffering effects of green exercise, and the importance of the context in which exercise takes place. This investigation of context effects examines both individual physiological responses (salivary cortisol) and the phenomenological interpretation of lived experiences of the intervention, reported by a subsample of participants in a randomized, controlled trial, in which healthy, physically inactive university students were randomly allocated to three activities: walking on a treadmill in a gym, walking in semi-natural recreational area, and sitting and watching nature-based videos on TV. The study found clear indications of context effects, notably in the connections between positive appraisals of perceived circumstances, enjoyment in the enacted context, and physiological stress-reduction.

The aim of this study was to explore the relation between Problematic Gaming Behaviour (PGB) and specific psychological factors (gaming motives, self-awareness of problematic gaming behaviour) and structural factors (game genres) among Finnish adolescents and young adults. A national survey of 271 respondents, aged 13 to 24, participated in the study. The study sample was randomly selected from the Population Register Center. Multiple regression analysis was used as a means of examining links between game genres, gaming motives and PGB. In addition, pairwise comparisons of a non-problematic gaming behavior group and a problematic gaming behavior group were used as a means of examining differences across game genre use and self-awareness of PGB. PGB was particularly associated with the use of a group of games encompassing role-playing, progression (e.g., character development), action and strategy features. The findings indicated that entertainment-achievement, social and escapism motives were associated with PGB. On the whole, this study emphasized that specific game genres and playing motives are involved in problematic use of digital game playing. © 2016 Springer Science+Business Media New York [less ▲]

This study examined the difference in the perception of time between young and older adults in a temporal bisection task with four different duration ranges from a few milliseconds (500 ms) to several seconds (30 s). In addition, individual cognitive capacities (short-term memory, working memory, processing speed, attention) were assessed with different neuropsychological tests. The results showed a general effect of age on the variability of time judgment, indicating a lower sensitivity to time in the old than in the younger adults, regardless of the duration range tested. In addition, the results showed that the individual differences in time sensitivity were explained by attention capacities, which decline with aging. [less ▲]

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. [less ▲]

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. [less ▲]

Background: Impairments in executive functions (EFs) are related to binge drinking in young adulthood, but research on how EFs influence future binge drinking is lacking. The aim of the current report is therefore to investigate the association between various EFs and later severity of, and change in, binge drinking over a prolonged period during young adulthood. Methods: At baseline, 121 students reported on their alcohol habits (the Alcohol use disorder identification test; Alcohol use questionnaire). Concurrently, EFs (working memory, reversal, set-shifting, response inhibition, response monitoring and decision-making (with ambiguity and implicit risk)) were assessed. Eighteen months later, information on alcohol habits for 103 of the participants were gathered. Data were analyzed by means of multilevel regression modeling. Results: Future severity of binge drinking was uniquely predicted by performance on the Information sampling task, assessing risky decision-making (β = -1.86, 95% CI: -3.69, -0.04). None of the study variables predicted severity or change in binge drinking. Conclusion: Future severity of binge was associated with making risky decisions in the prospect for gain, suggesting reward hypersensitivity. Future studies should aim at clarifying whether there is a causal association between decision-making style and binge drinking. Performance on all executive tasks was unrelated to change in binge drinking patterns; however, the finding was limited by overall small changes, and needs to be confirmed with longer follow-up periods.
