Motivational patterns as an instrument for predicting success in promising young football players

Psychological characteristics are crucial to identifying talents, which is why these are being incorporated in today’s multidimensional talent models. In addition to multidimensionality, talent studies are increasingly drawing on holistic theories of development, leading to the use of person-oriented approaches. The present study adopts such an approach by looking at the influence that motivational characteristics have on the development of performance, in a person-oriented way. For this purpose, it looks at how the constructs achievement motive, achievement goal orientation and self-determination interact with one another, what patterns they form and how these patterns are linked to subsequent sports success. 97 top young football players were questioned twice. Another year later, it was enquired which of these players had been selected for the U15 national team. At both measuring points, four patterns were identified, which displayed a high degree of structural and individual stability. As expected, the highly intrinsically achievement-oriented players were significantly more likely to move up into the U15 national team. The results point to the importance of favourable patterns of motivational variables in the form of specific types, for medium-term performance development among promising football talents, and thus provide valuable clues for the selection and promotion of those.

Towards a treaty instrument on marine genetic resources

Marine genetic resources other than fish and mammals are of increasing commercial interest and importance in genetic engineering, but fail being properly addressed in the law of the sea and in international economic law. The paper analyses the implication of the United Nations Convention on the Law of the Sea, the Convention on Biodiversity, the WTO Agreement on Trade Related Aspects of Intellectual Property Rights and related instruments under the auspices of WIPO. The paper argues that the triangle of these agreements does not adequately address marine genetic resources in particular in the high seas. Neither concerns of protecting biodiversity nor of access and benefit sharing find appropriate answers commensurate to the commercial potential of marine genetic resources. The paper suggests developing an instrument inspired by, and comparable to, the mechanisms developed by the International Treaty on Plant Genetic Resources for Food and Agriculture. The instrument would grant facilitated access to marine genetic resources and offer a more detailed set of rules with respect to the sharing of benefits resulting from their use, thereby addressing the existing legal gaps in a comprehensive way.

Zwangsmassnahmen als Instrument der Krankheitsbekämpfung: das Epidemiengesetz und die persönliche Freiheit

Das Auftreten einer gefährlichen Epidemie weckt unterschiedliche Erwartungen an den Staat: Gesunde fordern effiziente Krankheitsbekämpfung und Ansteckungsprävention; für Kranke und Infizierte steht dagegen der Schutz vor Diskriminierung sowie vor einschneidenden Eingriffen in die Persönlichkeitssphäre im Vordergrund. Im Spannungsfeld dieser teilweise gegenläufigen Interessen steht, wie heute das Beispiel AIDS zeigt, die Diskussion über den Einsatz von seuchenrechtlichen Zwangsmassnahmen und deren Vereinbarung mit dem Grundrecht der Persönlichen Freiheit. Die vorliegenden Leitlinien zur verfassungsmässigen Handhabung dieses heiklen Instruments richten sich in erster Linie an Gesundheitsbehörden, richterliche Instanzen und Ärzte.

Optical Tolerance Analysis of the Multi-Beam Limb Viewing Instrument STEAMR

In this paper, we report on an optical tolerance analysis of the submillimeter atmospheric multi-beam limb sounder, STEAMR. Physical optics and ray-tracing methods were used to quantify and separate errors in beam pointing and distortion due to reflector misalignment and primary reflector surface deformations. Simulations were performed concurrently with the manufacturing of a multi-beam demonstrator of the relay optical system which shapes and images the beams to their corresponding receiver feed horns. Results from Monte Carlo simulations show that the inserts used for reflector mounting should be positioned with an overall accuracy better than 100 μm (~ 1/10 wavelength). Analyses of primary reflector surface deformations show that a deviation of magnitude 100 μm can be tolerable before deployment, whereas the corresponding variations should be less than 30 μm during operation. The most sensitive optical elements in terms of misalignments are found near the focal plane. This localized sensitivity is attributed to the off-axis nature of the beams at this location. Post-assembly mechanical measurements of the reflectors in the demonstrator show that alignment better than 50 μm could be obtained.
