Given the uncertainty of outcome in sport, predicting the outcome of sporting contests is a major topic in sport sciences. This study examines the accuracy of expert predictions in the German Bundesliga and compares their predictions to those of sports economists. Prior to the start of each season, a set of distinguished experts (head coaches and players) express their subjective evaluations of the teams in school grades. While experts may be driven by irrational sentiments and may therefore systematically over- or underestimate specific teams, sports economists use observable characteristics to predict season outcomes. The latter typically use team wage bills given the positive pay–performance relationship as well as other factors (average team age, tenure, appearances on national team, and attendance). Using data from 15 consecutive Bundesliga seasons, the predictive accuracy of expert evaluations and sports economists is analysed. The results of separate estimations show that relative grade and relative wage bill significantly affect relative points, while age, tenure, appearances, and attendance are insignificant. In a joint model, relative grade and relative wage bill are still statistically significant, suggesting that the two types of predictions are complements rather than substitutes. Consequently, football experts and sports economists seem to rely on completely different sources of information when making their predictions. 相似文献

We examined the influence of caffeine supplementation on cognitive performance and perceptual responses in female team-game players taking low-dose monophasic oral contraceptives of the same hormonal composition. Ten females (24 ± 4 years; 59.7 ± 3.5 kg body mass; 2–6 training sessions per week) took part in a randomised, double-blind, placebo-controlled crossover-design trial. A 90-min intermittent treadmill-running protocol was completed 60 min following ingestion of a capsule containing either 6 mg ? kg?1 anhydrous caffeine or artificial sweetener (placebo). Perceptual responses (ratings of perceived exertion (RPE), feeling scale (FS), felt arousal scale (FAS)), mood (profile of mood states (POMS)) and cognitive performance (Stroop test, choice reaction time (CRT)) were completed before, during and after the exercise protocol, as well as after ~12 h post exercise. Caffeine ingestion significantly enhanced the ratings of pleasure (P = 0.008) and arousal (P = 0.002) during the exercise protocol, as well as increased vigour (POMS; P = 0.007), while there was a tendency for reduced fatigue (POMS; P = 0.068). Caffeine ingestion showed a tendency to decrease RPE (P = 0.068) and improve reaction times in the Stroop (P = 0.072) and CRT (P = 0.087) tests. Caffeine supplementation showed a positive effect on perceptual parameters by increasing vigour and a tendency to decrease fatigue during intermittent running activity in female games players taking low-dose monophasic oral contraceptive steroids (OCS). 相似文献

Family, friend and neighbor (FFN) child caregivers represent a significant proportion of caregivers for young children. Yet, these caregivers receive little support for their services. In 2003, the First 5 California Children and Families Commission (First 5 California) began a study to determine the work-related needs of FFN caregivers in California. This paper reports on the results of all study activities, including focus groups and interviews with caregivers and parents. It details the specific needs related to licensing, materials and equipment, education and training, and support systems that were identified by FFN caregivers, parents, and other stakeholders as being important to improve the quality and working conditions of FFN care. It also discusses needs of agencies that provide services to FFN caregivers, including awareness of and knowledge about the population, funding and other resources, and professional development topics. 相似文献

Children aged 4 to 10 years old were asked to draw a person standing absolutely still and a person walking very fast so that someone not present would know from the pictures alone what had been depicted. Even at four some children were able to convey the difference to a viewer and there was increasing success with age. The number of differentiating cues increased with age and there was an age‐related trend in the order in which specific cues appeared in the drawings. The ability of the children to respond flexibly to the task gives no support to notions of rigid mental representations determining what young children can draw. It is argued that contrast tasks are a useful tool for investigating problem solving skills in the domain of drawing and could be used to extend children's skill by providing an occasion for explicit dialogue about how representational information is conveyed to a viewer. 相似文献

Educators of the deaf were long considered "highly qualified" if they obtained state licensure from approved deaf education programs. But the No Child Left Behind Act (2001) redefined qualifications based on core academic content areas, without recognizing disability-specific expertise. NCLB's reauthorization will provide opportunities for examining definitions of "highly qualified" and ensuring that both general and special educators are appropriately prepared. Under the Individuals With Disabilities Education Act, educators of the deaf are primarily responsible for supporting implementation of each assigned student's individualized education program. When done skillfully and knowledgeably, IEP execution maximizes learning outcomes, and therefore would support NCLB mandates for improved student achievement. Instead of academic attainment alone, the primary "qualification" of educators of the deaf should be training and expertise in providing communication, learning, and assistive technology supports that allow access to academic content and, ultimately, address deaf students' historical underachievement. 相似文献

ABSTRACT Undergraduate research is value-added experiential learning that cultivates creative and intentional learners in and out of the classroom. However, only recently have researchers begun investigating the mechanisms related to mentoring undergraduate researchers, with scant attention being paid to the experiences of underrepresented minority (URM) faculty members. Using unique data collected from an online survey of faculty members (overall N = 215, URM n = 25), we find departmental and institutional support to be the key factors correlated with mentoring undergraduate research students. Reported support is more influential for URM faculty than white faculty, providing evidence of the importance of institutional policy as a mechanism to facilitate URM faculty participation in the high impact practice of mentoring undergraduate researchers. The findings are discussed in the context of institutional initiatives designed to support student and faculty success in the 21st century. 相似文献
