Becoming Mediterranean:Semantic Shifts in Germany Asylum and Refugee Discourse
No full textThe European ‘refugee crisis’ has seen the Mediterranean described as: a hot spot in need of better governance and border policing; the world’s deadliest border; and as a humanitarian catastrophe. In Germany, the initial default option was to treat the various articulations of crisis as localized. Keeping the Mediterranean (and thus the crisis) at arm’s length was facilitated by the Dublin II regulations stipulating that asylum claims would only be processed in the state where they were first made. Only in 2015, when large numbers of refugees arrived, the Mediterranean was rearticulated as concerning ‘us’ rather than ‘them’. Focusing on German asylum and refugee debates, this article traces such semantic shifts to show how, counter-intuitively, becoming Mediterranean is enabled by a tacit process of de-Europeanization which instrumentally calls for European solutions only when the ‘crisis’ reaches the national level
Quantifying change of direction load using positional data from small-sided games in soccer
No full textPURPOSE: Quantifying change of direction (COD) load through positional data from small-sided games (SSG) and assess its criterion and construct validity.METHODS: Elite male youth soccer players (n = 25, 16.8 ± 1.3 years) played three SSG (5v5, 5×4 min) with different field dimensions (small [40×30 m], medium [55×38 m], large [70×45 m]). Positional data of the players was obtained with a Local Position Measurement system. COD load (AU) was quantified based on the combination of velocity and change in heading direction. Additionally, total distance covered, running distance, acceleration count, deceleration count, and Rating of Perceived Exertion were measured. Criterion validity was assessed by correlating COD load and the load indicators. Construct validity was determined by testing the differences between the SSG field dimensions.RESULTS: Strong correlations were determined between COD load and total distance covered (r = 0.74, p < .01) and running distance (r = 0.84, p < .01). Middle and large field size resulted in highest COD load (p < .05).CONCLUSION: These results suggest that the COD load measure shows sufficient criterion and construct validity.</p
Opinion-shopping:Firm versus Partner-level Evidence
No full textEmploying Lennox’s (2000) methodology on a uniquely long time series of Spanish companies’ data, we find evidence of successful audit opinion-shopping through the firm switching decision. However, in contrast to Chen et al. (2016) in the Chinese setting, we find no evidence of successful opinion-shopping at the partner level. This supports the thesis that the audit market characteristics that are key to promote or deter opinion shopping might differ at the firm and partner level within a country, with consequences for audit quality. In addition, we provide evidence on the strategies that companies use to secure more favourable opinions. The results suggest that companies may prefer to opinion shop at the partner level, which is consistent with the argument that the costs and benefits associated with opinion-shopping are different at these two levels, and lead to different outcomes
Renal Normothermic Machine Perfusion:The Road Toward Clinical Implementation of a Promising Pretransplant Organ Assessment Tool
No full textThe increased utilization of high-risk renal grafts for transplantation requires optimization of pretransplant organ assessment strategies. Current decision-making methods to accept an organ for transplantation lack overall predictive power and always contain an element of subjectivity. Normothermic machine perfusion (NMP) creates near-physiological conditions, which might facilitate a more objective assessment of organ quality prior to transplantation. NMP is rapidly gaining popularity, with various transplant centers developing their own NMP protocols and renal viability criteria. However, to date, no validated sets of on-pump viability markers exist nor are there unified NMP protocols. This review provides a critical overview of the fundamentals of current renal NMP protocols and proposes a framework to approach further development of ex vivo organ evaluation. We also comment on the potential logistical implications of routine clinical use of NMP, which is a more complex procedure compared to static cold storage or even hypothermic machine perfusion.

Drivers of autonomous vehicles-analyzing consumer preferences for self-driving car brand extensions
No full textAutonomous cars are considered to be the next disruptive innovation that will affect consumers. It can be expected that not only traditional automakers will enter this market (e.g., Ford) but also technology companies (e.g., Google) and newer companies dedicated to self-driving cars (e.g., Tesla). We take a brand extension perspective and analyze to what extent consumers prefer autonomous cars from these brand categories. Our empirical study is based on discrete choice experiments about adopting autonomous vehicles in a purchase scenario and in a renting context. Our findings show that brands play a central role when making autonomous driving decisions. Brand preferences differ systematically when buying versus renting a self-driving car. While technology brands are most preferred overall, consumers favor automaker brands over new brands only when purchasing, not when renting. We further disentangle the brand strength into the marginal effects of image associations. For example, Google's strong brand positioning can be explained by experiences with the parent brand, but it could still improve brand strength by highlighting the relevance of the associated brand portfolio for self-driving cars. The effect of these brand extension success factors differs between parent-brand categories and also between the renting and purchasing scenarios, which requires a dedicated brand management.</p
Higher-order evidence and losing one's conviction
No full textThere has been considerable puzzlement over how to respond to higher-order evidence. The existing dilemmas can be defused by adopting a ‘two-dimensional’ representation of doxastic attitudes which incorporates not only substantive uncertainty about which first-order state of affairs obtains but also the degree of conviction with which we hold the attitude. This makes it possible that in cases of higher-order evidence the evidence sometimes impacts primarily on our conviction, rather than our substantive uncertainty. I argue that such a two-dimensional representation is naturally developed by making use of imprecise probabilities
Care improves self-reported daily functioning of adolescents with emotional and behavioural problems
No full textEmotional and behavioural problems (EBP) have a negative impact on various life domains of adolescents. Receiving care for EBP may improve the functioning of adolescents with EBP, but evidence on long-term outcomes in real-life settings is lacking. We, therefore, investigated self-reported functioning in different life domains of adolescents with various EBP, and the role of care during a three-year period. We used data from the TAKECARE study, which consist of a care and community cohort. We followed adolescents aged 12 and over (n = 733) during 3 years over five assessment rounds. Using the Strengths and Difficulties Questionnaire, self-reported functioning was measured in four life domains: home life, friendships, classroom learning and leisure activities. We categorized the respondents into four groups: (1) adolescents without emotional and behavioural problems (n = 298); (2) adolescents with emotional problems (n = 192); (3) adolescents with behavioural problems (n = 80); and (4) adolescents with both emotional and behavioural problems (n = 163). The development of functioning over time was analyzed using longitudinal ordinal (probit) regression analyses. Adolescents with both emotional and behavioural problems reported poorer functioning at baseline in all domains and adolescents who received care reported poorer functioning at baseline compared to adolescents who did not receive care. Regarding the change in functioning during the 3 years, adolescents who received care showed improved functioning in all domains. We found improved functioning after care, even if the problems may not have been solved. Psychosocial care can contribute to the functioning of adolescents with EBP, which can have major effects on their future life.</p
Temporal dynamics of depression, cognitive performance and sleep in older persons with depressive symptoms and cognitive impairments:a series of eight single-subject studies
No full textOBJECTIVES: To investigate the presence, nature and direction of the daily temporal association between depressive symptoms, cognitive performance and sleep in older individuals.DESIGN, SETTING, PARTICIPANTS: Single-subject study design in eight older adults with cognitive impairments and depressive symptoms.MEASUREMENTS: For 63 consecutive days, depressive symptoms, working memory performance and night-time sleep duration were daily assessed with an electronic diary and actigraphy. The temporal associations of depressive symptoms, working memory and total sleep time were evaluated for each participant separately with time-series analysis (vector autoregressive modeling).RESULTS: For seven out of eight participants we found a temporal association between depressive symptoms and/or sleep and/or working memory performance. More depressive symptoms were preceded by longer sleep duration in one person (r = 0.39; p < .001), by longer or shorter sleep duration than usual in one other person (B = 0.49; p < .001), by worse working memory in one person (B = -0.45; p = .007), and by better working memory performance in one other person (B = 0.35; p = .009). Worse working memory performance was preceded by longer sleep duration (r = -.35; p = .005) in one person, by shorter or longer sleep duration in three other persons (B = -0.76; p = .005, B = -0.61; p < .001; B = -0.34; p = .002), and by more depressive symptoms in one person (B = -0.25; p = .009).CONCLUSION: The presence, nature and direction of the temporal associations between depressive symptoms, cognitive performance and sleep differed between individuals. Knowledge of personal temporal associations may be valuable for the development of personalized intervention strategies in order to maintain their health, quality of life, functional outcomes and independence.</p
