Integrierte Entwicklung von Automotive-Software mit AutoFocus

Zur Beherrschung der komplexen vernetzten und verteilten Funktionen von Automotive-Software ist eine Beschreibung des zu erstellenden Systems auf verschiedenen Abstraktionsebenen und schrittweise überg?nge zwischen diesen Ebenen notwendig. Neben der Definition geeigneter Ebenen werden zur Unterstützung echtzeitkritischer Systemanteile ein einheitliches Berechnungsmodell, ebenenspezifische Beschreibungstechniken, sowie methodische Regeln für diese Abstraktionsebenen eingeführt und in den Werkzeugprototypen AutoFocus integriert.     

The effect of ball carrying method on sprint speed in rugby union football players

Different methods of ball carrying can be used when a player runs with the ball in rugby union. We examined how three methods of ball carrying influenced sprinting speed: using both hands, under the left arm and under the right arm. These methods were compared with running without the ball. Our aim was to determine which method of ball carrying optimizes sprinting speed. Altogether, 48 rugby union players (age 21 +/- 2 years, height 1.83 +/- 0.1 m, body mass 85.3 +/- 12 kg, body fat 14 +/- 5%; mean +/- s) were recruited. The players performed twelve 30-m sprints in total (each player performed three trials under each of three methods of carrying the ball and sprinting without the ball). The design of the study was a form of Latin rectangle, balanced across the trial order for each of the methods and for pairwise combinations of the methods in blocks of four per trial. Each sprint consisted of a 10-m rolling start, followed by a 20-m timed section using electronic timing gates. Compared with sprinting 20 m without the ball (2.58 +/- 0.16 s), using both hands (2.62 +/- 0.16 s) led to a significantly slower time (P < 0.05). Sprinting 20 m with the ball under the left arm (2.61 +/- 0.15 s) or under the right arm (2.60 +/- 0.17 s) was significantly quicker than when using 'both hands' (P < 0.05), and both these methods were significantly slower than when running without the ball (P < 0.05). Accordingly, running with the ball in both hands led to the greatest decrement in sprinting performance, although carrying the ball under one arm also reduced the players' sprinting ability. Our results indicate that to gain a speed advantage players should carry the ball under one arm.     

Teacher learning in the context of educational innovation: Learning activities and learning outcomes of experienced teachers

This longitudinal study was aimed at increasing our understanding of how teachers learn. It was conducted within a national innovation programme in secondary education. During one year 94 teachers reported six learning experiences using digital logs. The learning experiences were content-analysed in terms of learning activities and learning outcomes. The former comprised six main categories, namely experimenting, considering own practice, getting ideas from others, experiencing friction, struggling not to revert to old ways, and avoiding learning—the first two categories being reported most frequently. Reported learning outcomes referred to changes in knowledge and beliefs, emotions, practices, and intentions for practice, with changes in knowledge and beliefs being reported most frequently and changes in teaching practices being reported rarely. Learning activities were associated significantly with all measures of learning outcomes. Type of learning environment was significantly associated with learning activities and learning outcomes. Results are discussed with respect to ways of fostering teacher learning.     

Quality Assessment, Student Need, and Pastoral Care at the University of Strathclyde

For young people moving from school to higher education, the continued provision of high quality pastoral care should be an important consideration. However, though all institutions provide some sort of service, its quality can vary significantly. Even where provision has been good, it has normally been seen as a 'bolt‐on' extra, rather than something central to the student's experience. At the University of Strathclyde, a key element in the creation of a more effective and integrated approach has been the development of the personal tutor role into that of the more clearly defined and structured one of Academic Counsellor.     

Environmental paper buying — best practice

In this article the environmental and commercial issues, which are an integral part of the need for, and practice of, recycling paper, are explored and explained. Although of particular interest to publishers, paper buyers and printers this is a subject that no one can afford to ignore.
