Ein Testverfahren für optimierende Codegeneratoren     

Ingo Stürmer  Mirko Conrad 《Informatik - Forschung und Entwicklung》2005,14(1):213-223

Die im Rahmen der Modell-basierten Entwicklung eingebetteter Steuerungs- und Regelungssoftware eingesetzten optimierenden Codegeneratoren müssen einer intensiven Qualit?tssicherung unterzogen werden. Dem Einsatz von Testsuiten kommt dabei eine zentrale Rolle zu. Der Beitrag beschreibt den Aufbau einer modularen Testsuite für Codegeneratoren und schl?gt einen Testansatz vor, der eine systematische Prüfung der vom Codegenerator angewendeten Optimierungstechniken erm?glicht.  相似文献

'So few fat ones grow old': diet, health, and virtue in the golden age of rising life expectancy     

Veit HZ 《Endeavour》2011,35(2-3):91-98

Life expectancy and chronic disease rates both rose dramatically in the United States during the first third of the twentieth century. As a result of this concurrence, Americans in this era increasingly thought about things they could do to extend their own lives, especially eating less, exercising more, and limiting stress, all factors thought to reduce chronic disease. New recognition of the correlation between daily physical habits and long lives made longevity look like a sign of virtue. At the same time, amidst discussions about the relationship between individual longevity and national vitality, this correlation also contributed to Americans' moralization of diet, exercise, and emotional self-control.  相似文献   

The local impact of global climate change: reporting on landscape transformation and threatened identity in the English regional newspaper press     

Brown T  Budd L  Bell M  Rendell H 《Public understanding of science (Bristol, England)》2011,20(5):658-673

This paper contributes to extant understandings of media representations of climate change by examining the role of the English regional newspaper press in the transformation and dissemination of climate change discourse. Unlike previous accounts, this paper contends that such newspapers shape public understandings of climate change in ways that have yet to be adequately charted. With this in mind, this paper examines the ways in which global climate change is translated into a locally relevant phenomenon. That is, it focuses on its "domestication." Although we acknowledge that there are a number of ways in which this process occurs, specific attention is drawn to stories that highlight the destruction of local landscape features, the transformation of important habitats, and the arrival of "alien" species. The broader significance of such stories is considered in relation to long-standing debates concerning the importance of landscape to notions of national and regional identity.  相似文献   

Nutritional, lifestyle, and weight control practices of professional jockeys   总被引：1，自引：1，他引：0  

Dolan E  O'Connor H  McGoldrick A  O'Loughlin G  Lyons D  Warrington G 《Journal of sports sciences》2011,29(8):791-799

In this study, we describe diet and lifestyle practices of professional jockeys. Participants completed a 59-item nutrition, lifestyle, and health questionnaire (n = 21) and a 7-day estimated food diary (n = 18). Acute weight loss strategies included the use of saunas (86%), exercising to induce sweating (81%), and restricted energy intake (71%). Of the smokers (38%), 56% used smoking to control weight. Most (86%) jockeys reported attaining a 2-kg weight loss for racing (if required) 24-48 h before or on the designated race-day. Mean daily energy intake (1803 ± 564 kcal) was low and appeared to provide an insufficient availability of energy for sustainment of usual daily and metabolic processes. Carbohydrate intake (3.7 ± 1.3 g · kg?1) was below recommendations for athletes. A substantial proportion of jockeys failed to meet the estimated average requirement and lower threshold intake for a number of micronutrients. Jockeys consumed well below (0-2) the recommended five daily servings of fruit and vegetables set by the World Health Organization. Pressures of the jockey lifestyle and rigid weight limits appear to encourage unhealthy weight management practices in this group and may risk long term-health.  相似文献   

Acquisition of a complex basketball-dribbling task in school children as a function of bilateral practice order     

Stöckel T  Weigelt M  Krug J 《Research quarterly for exercise and sport》2011,82(2):188-197

The purpose of this study was to investigate order-of-practice effects for the acquisition of a complex basketball skill in a bilateral transfer paradigm. The task required participants to dribble as fast as possible in slalom-like movements across six javelins and return to the initial position. Fifty-two right-handed school children (M age = 11.7years) practiced this skill in eight sessions over 4 weeks under one of two training schedules: (a) with the dominant hand, before changing to their nondominant hand (D-ND group), or (b) with the nondominant hand, before changing to the dominant hand (ND-D group). All tests were conducted with the right hand or the left hand only, and a transfer test was given with both hands alternating. The results of a retention test yielded significantly larger learning gains for the ND-D group as compared to the D-ND group. It is interesting that this performance advantage was independent of the respective hand tested. The same pattern of result was found in the transfer test, with significantly shorter movement times for the ND-D group with both hands alternating. Such order-of-practice effects for the acquisition of complex skills can be explained with hemispheric brain asymmetries for the processing of specific task requirements.  相似文献   

The effects of skiing velocity on mechanical aspects of diagonal cross-country skiing     

Erik Andersson  Barbara Pellegrini  Øyvind Sandbakk  Thomas Stüggl  Hans-Christer Holmberg 《Sports biomechanics / International Society of Biomechanics in Sports》2014,13(3):267-284

Cycle and force characteristics were examined in 11 elite male cross-country skiers using the diagonal stride technique while skiing uphill (7.5°) on snow at moderate (3.5 ± 0.3 m/s), high (4.5 ± 0.4 m/s), and maximal (5.6 ± 0.6 m/s) velocities. Video analysis (50 Hz) was combined with plantar (leg) force (100 Hz), pole force (1,500 Hz), and photocell measurements. Both cycle rate and cycle length increased from moderate to high velocity, while cycle rate increased and cycle length decreased at maximal compared to high velocity. The kick time decreased 26% from moderate to maximal velocity, reaching 0.14 s at maximal. The relative kick and gliding times were only altered at maximal velocity, where these were longer and shorter, respectively. The rate of force development increased with higher velocity. At maximal velocity, sprint-specialists were 14% faster than distance-specialists due to greater cycle rate, peak leg force, and rate of leg force development. In conclusion, large peak leg forces were applied rapidly across all velocities and the shorter relative gliding and longer relative kick phases at maximal velocity allow maintenance of kick duration for force generation. These results emphasise the importance of rapid leg force generation in diagonal skiing.  相似文献   

Ability emotional intelligence,trait emotional intelligence,and academic success in British secondary schools: A 5 year longitudinal study     

Pamela Qualter  Kathryn.J. Gardner  Debbie.J. Pope  Jane.M. Hutchinson  Helen E. Whiteley 《Learning and individual differences》2012,22(1):83-91

This study examines the long-term effects of ability- and trait EI on academic performance for British adolescents. The sample comprised 413 students from three secondary schools in the North-West of England. Students completed tests of ability EI, trait EI, personality, and cognitive ability in Year 7 (mean age = 11 years 2 months). Performance data at the end of Year 11 (mean age = 15 years 10 months) were collected. Structural Equation Modelling examined the longitudinal relationships between latent variables of these constructs. Results show that the importance of ability EI resides in the fact that it moderates the effect of cognitive ability on performance in Year 11. Trait EI has a direct effect on Year 11 performance for boys only. This suggests that initiatives that help to develop ability EI and increase trait EI offer educators opportunities to improve educational achievement.  相似文献
