Die Europäische Union auf dem Weg zur Verfassungsrechtsgemeinschaft

Obwohl der Ursprung der europäischen Einigungsgeschichte im wirtschaftlichen Bereich lag, hatte die Integration von Beginn an auch politischen Charakter. Schon die römischen Verträge enthielten Ansätze einer Konstitutionalisierung und auch die Bezeichnung der Verträge als Verfassung wurde seit den 60er-Jahren unter Rechtswissenschaftlern immer gebräuchlicher, auch wenn dies stets umstritten war. Unabhängig vom Streit über den Verfassungsbegriff hat die von den Verträgen gebildete Rechtsordnung jedenfalls inhaltlich Verfassungscharakter. Sie enthält Regelungen, die man gemeinhin mit einer Staatsverfassung verbindet. Die europäische Integration war stets von verfassungsrechtlichen Idealen getragen, weshalb man die Mitgliedstaaten auch als eine Verfassungsrechtsgemeinschaft bezeichnen kann. Bedeutende Weiterentwicklungen erfuhr der Konstitutionalisierungsprozess mit der Konventsmethode und der Erarbeitung der Grundrechte-Charta. Fortgesetzt wurde dieser Prozess mit dem Entwurf über den Verfassungsvertrag für Europa. Da in ihm typische Gehalte einer Verfassung verkörpert sind, verdient er durchaus auch diese Bezeichnung. Auf seiner Basis sollte ein schlanker, übersichtlicher und verständlicher Verfassungstext geschaffen werden, der die Reform und Integration Europas weiter führt und ein Instrument der Identitätsstiftung sein kann.

Detecting single-target changes in multiple object tracking: The case of peripheral vision.

In sports games, it is often necessary to perceive a large number of moving objects (e.g., the ball and players). In this context, the role of peripheral vision for processing motion information in the periphery is often discussed especially when motor responses are required. In an attempt to test the basal functionality of peripheral vision in those sports-games situations, a Multiple Object Tracking (MOT) task that requires to track a certain number of targets amidst distractors, was chosen. Participants’ primary task was to recall four targets (out of 10 rectangular stimuli) after six seconds of quasi-random motion. As a second task, a button had to be pressed if a target change occurred (Exp 1: stop vs. form change to a diamond for 0.5 s; Exp 2: stop vs. slowdown for 0.5 s). While eccentricities of changes (5-10° vs. 15-20°) were manipulated, decision accuracy (recall and button press correct), motor response time as well as saccadic reaction time were calculated as dependent variables. Results show that participants indeed used peripheral vision to detect changes, because either no or very late saccades to the changed target were executed in correct trials. Moreover, a saccade was more often executed when eccentricities were small. Response accuracies were higher and response times were lower in the stop conditions of both experiments while larger eccentricities led to higher response times in all conditions. Summing up, it could be shown that monitoring targets and detecting changes can be processed by peripheral vision only and that a monitoring strategy on the basis of peripheral vision may be the optimal one as saccades may be afflicted with certain costs. Further research is planned to address the question whether this functionality is also evident in sports tasks.

Reduced foveal vision enhances peripheral monitoring and peripheral event detection

Introduction: Although it seems plausible that sports performance relies on high-acuity foveal vision, it could be empirically shown that myoptic blur (up to +2 diopters) does not harm performance in sport tasks that require foveal information pick-up like golf putting (Bulson, Ciuffreda, & Hung, 2008). How myoptic blur affects peripheral performance is yet unknown. Attention might be less needed for processing visual cues foveally and lead to better performance because peripheral cues are better processed as a function of reduced foveal vision, which will be tested in the current experiment. Methods: 18 sport science students with self-reported myopia volunteered as participants, all of them regularly wearing contact lenses. Exclusion criteria comprised visual correction other than myopic, correction of astigmatism and use of contact lenses out of Swiss delivery area. For each of the participants, three pairs of additional contact lenses (besides their regular lenses; used in the “plano” condition) were manufactured with an individual overcorrection to a retinal defocus of +1 to +3 diopters (referred to as “+1.00 D”, “+2.00 D”, and “+3.00 D” condition, respectively). Gaze data were acquired while participants had to perform a multiple object tracking (MOT) task that required to track 4 out of 10 moving stimuli. In addition, in 66.7 % of all trials, one of the 4 targets suddenly stopped during the motion phase for a period of 0.5 s. Stimuli moved in front of a picture of a sports hall to allow for foveal processing. Due to the directional hypotheses, the level of significance for one-tailed tests on differences was set at α = .05 and posteriori effect sizes were computed as partial eta squares (ηρ2). Results: Due to problems with the gaze-data collection, 3 participants had to be excluded from further analyses. The expectation of a centroid strategy was confirmed because gaze was closer to the centroid than the target (all p < .01). In comparison to the plano baseline, participants more often recalled all 4 targets under defocus conditions, F(1,14) = 26.13, p < .01, ηρ2 = .65. The three defocus conditions differed significantly, F(2,28) = 2.56, p = .05, ηρ2 = .16, with a higher accuracy as a function of a defocus increase and significant contrasts between conditions +1.00 D and +2.00 D (p = .03) and +1.00 D and +3.00 D (p = .03). For stop trials, significant differences could neither be found between plano baseline and defocus conditions, F(1,14) = .19, p = .67, ηρ2 = .01, nor between the three defocus conditions, F(2,28) = 1.09, p = .18, ηρ2 = .07. Participants reacted faster in “4 correct+button” trials under defocus than under plano-baseline conditions, F(1,14) = 10.77, p < .01, ηρ2 = .44. The defocus conditions differed significantly, F(2,28) = 6.16, p < .01, ηρ2 = .31, with shorter response times as a function of a defocus increase and significant contrasts between +1.00 D and +2.00 D (p = .01) and +1.00 D and +3.00 D (p < .01). Discussion: The results show that gaze behaviour in MOT is not affected to a relevant degree by a visual overcorrection up to +3 diopters. Hence, it can be taken for granted that peripheral event detection was investigated in the present study. This overcorrection, however, does not harm the capability to peripherally track objects. Moreover, if an event has to be detected peripherally, neither response accuracy nor response time is negatively affected. Findings could claim considerable relevance for all sport situations in which peripheral vision is required which now needs applied studies on this topic. References: Bulson, R. C., Ciuffreda, K.

Detecting single-target changes in multiple object tracking: The case of peripheral vision

In the current study it is investigated whether peripheral vision can be used to monitor multi-ple moving objects and to detect single-target changes. For this purpose, in Experiment 1, a modified MOT setup with a large projection and a constant-position centroid phase had to be checked first. Classical findings regarding the use of a virtual centroid to track multiple ob-jects and the dependency of tracking accuracy on target speed could be successfully replicat-ed. Thereafter, the main experimental variations regarding the manipulation of to-be-detected target changes could be introduced in Experiment 2. In addition to a button press used for the detection task, gaze behavior was assessed using an integrated eye-tracking system. The anal-ysis of saccadic reaction times in relation to the motor response shows that peripheral vision is naturally used to detect motion and form changes in MOT because the saccade to the target occurred after target-change offset. Furthermore, for changes of comparable task difficulties, motion changes are detected better by peripheral vision than form changes. Findings indicate that capabilities of the visual system (e.g., visual acuity) affect change detection rates and that covert-attention processes may be affected by vision-related aspects like spatial uncertainty. Moreover, it is argued that a centroid-MOT strategy might reduce the amount of saccade-related costs and that eye-tracking seems to be generally valuable to test predictions derived from theories on MOT. Finally, implications for testing covert attention in applied settings are proposed.

Stimulation of bacteriophage T4 middle transcription by the T4 proteins MotA and AsiA occurs at two distinct steps in the transcription cycle

The bacteriophage T4 encodes proteins that are responsible for tightly regulating mRNA synthesis throughout phage development in Escherichia coli. The three classes of T4 promoters (early, middle, and late) are utilized sequentially by the host RNA polymerase as a result of phage-induced modifications. One such modification is the tight binding of the T4 AsiA protein to the σ70 subunit of the RNA polymerase. This interaction is pivotal for the transition between T4 early and middle transcription, since it both inhibits recognition of host and T4 early promoters and stimulates T4 middle mode synthesis. The activation of T4 middle transcription also requires the T4 MotA protein, bound specifically to its recognition sequence, the “Mot box,” which is centered at position −30 of these promoters. Accordingly, the two T4 proteins working in concert are sufficient to effectively switch the transcription specificity of the RNA polymerase holoenzyme. Herein, we investigate the mechanism of transcription activation and report that, while the presence of MotA and AsiA increases the initial recruitment of RNA polymerase to a T4 middle promoter, it does not alter the intrinsic stability of the discrete complexes formed. In addition, we have characterized the RNA polymerase-promoter species by UV laser footprinting and followed their evolution from open into initiating complexes. These data, combined with in vitro transcription assays, indicate that AsiA and MotA facilitate promoter escape, thereby stimulating the production of full-length transcripts.

Assessing Needs of Care in European Nations. ENEPRI Policy Brief No. 14, 28 December 2012

This Policy Brief presents the research questions, main results and policy implications and recommendations of the seven Work Packages that formed the basis of the ANCIEN research project, financed under the 7th EU Research Framework Programme of the European Commission. Carried out over a 44-month period and involving 20 partners from EU member states, the project principally concerns the future of long-term care (LTC) for the elderly in Europe and addresses two questions in particular: How will need, demand, supply and use of LTC develop? How do different systems of LTC perform?

Performance of Long-Term Care Systems in Europe. ENEPRI Research Report No. 117, 21 December 2012

This report evaluates the performance of long-term care (LTC) systems in Europe, with a special emphasis on four countries that were selected in Work Package 1 of the ANCIEN project as representative of different LTC systems: Germany, the Netherlands, Spain and Poland. Based on a performance framework, we use the following four core criteria for the evaluation: the quality of life of LTC users, the quality of care, equity of LTC systems and the total burden of LTC (consisting of the financial burden and the burden of informal caregiving). The quality of life is analysed by studying the experience of LTC users in 13 European countries, using data from the Survey of Health, Ageing and Retirement in Europe (SHARE). Older persons with limitations living at home have the highest probability of receiving help (formal or informal) in Germany and the lowest in Poland. Given that help is available, the sufficiency of the help is best ensured in Switzerland, Italy and the Netherlands. The indirectly observed properties of the LTC system are most favourable in France. An older person who considers all three aspects important might be best off living in Belgium or Switzerland. The horizontal and vertical equity of LTC systems are analysed for the four representative countries. The Dutch system scores highest on overall equity, followed by the German system. The Spanish and Polish systems are both less equitable than the Dutch and German systems. To show how ageing may affect the financial burden of LTC, projections until 2060 are given for LTC expenditures for the four representative countries. Under the base scenario, for all four countries the proportions of GDP spent on public and private LTC are projected to more than double between 2010 and 2060, and even treble in some cases. The projections also highlight the large differences in LTC expenditures between the four countries. The Netherlands spends by far the most on LTC. Furthermore, the report presents information for a number of European countries on quality of care, the burden of informal caregiving and other aspects of performance. The LTC systems for the four representative countries are evaluated using the four core criteria. The Dutch system has the highest scores on all four dimensions except the total burden of care, where it has the second-best score after Poland. The German system has somewhat lower scores than the Dutch on all four dimensions. The relatively large role for informal care lowers the equity of the German system. The Polish system excels in having a low total burden of care, but it scores lowest on quality of care and equity. The Spanish system has few extreme scores. Policy implications are discussed in the last chapter of this report and in the Policy Brief based on this report.

La relation entre le climat scolaire, le contexte scolaire et l'adoption des différents rôles lors d’une situation de violence scolaire

Le sujet de la présente étude est la violence scolaire, phénomène complexe et polysémique qui préoccupe légitimement le monde de l’éducation depuis plus de trente ans. À partir des analyses factorielles exploratoires, analyses de variance factorielle et finalement analyses multivariées de covariance, cette recherche vise plus précisément à dégager la relation entre le climat scolaire, le contexte scolaire et les différents rôles adoptés par les élèves du niveau secondaire lors d’une situation de violence scolaire. Les données de la présente étude ont été collectées par Michel Janosz et son équipe pendant l’année 2010, dans quatre établissements éducatifs provenant d’une commission scolaire de la grande région de Montréal. L’échantillon de départ est composé de 1750 élèves qui fréquentent des classes ordinaires et spéciales du premier et deuxième cycle du secondaire âgés entre 10 et 18 ans. Pour fins d’analyse, deux petites écoles ainsi que les classes spéciales ont été retirées. Il demeure donc 1551 élèves dans l’échantillon initial analysé. Les résultats des analyses permettent de constater d’une part, la relation significative existante entre les dimensions du climat scolaire et l’adoption des différents rôles lors d’une situation de violence scolaire, les climats d’appartenance et de sécurité étant les plus importants, et d’autre part d’observer des différences dans les perceptions que les élèves ont de la violence scolaire selon le niveau et selon l’école.

La québécité dans le théâtre contemporain Mythanalyse de Scotstown, Yukonstyle et Félicité

Ce mémoire aborde trois oeuvres du théâtre québécois contemporain, Scotstown de Fabien Cloutier, Yukonstyle de Sarah Berthiaume et Félicité d’Olivier Choinière dans le but de les comparer. Cette comparaison doit alimenter une réflexion sur le concept de québécité, que le présent mémoire définit comme la mise en place d’un traitement de l’identité qui encourage le développement d’une certaine ambivalence identitaire. En stipulant que les discours identitaires sont empreints de ce que Gérard Bouchard appelle les mythes sociaux, ce mémoire analyse le corpus proposé pour en extraire les parts rationnelles de ces mythes, mais aussi les parts émotionnelles, qui agissent comme fondation de l’identité au même titre que la raison. Ce faisant, ce mémoire a pour ambition de déplacer une perception de la québécité ancrée dans une tradition historique et politique influencée par le nationalisme pour ramener ce concept vers une définition plus large, mais aussi plus polysémique pour interpréter l’histoire de la dramaturgie québécoise, qui entretient depuis la Révolution tranquille un rapport ironiquement ambivalent à l’égard des discours identitaires.
