Identifying match events that are related to match outcome is an important task in football match analysis. Here we have used generalised mixed linear modelling to determine relationships of 16 football match events and 1 contextual variable (game location: home/away) with the match outcome. Statistics of 320 close matches (goal difference ≤ 2) of season 2012–2013 in the Spanish First Division Professional Football League were analysed. Relationships were evaluated with magnitude-based inferences and were expressed as extra matches won or lost per 10 close matches for an increase of two within-team or between-team standard deviations (SD) of the match event (representing effects of changes in team values from match to match and of differences between average team values, respectively). There was a moderate positive within-team effect from shots on target (3.4 extra wins per 10 matches; 99% confidence limits ±1.0), and a small positive within-team effect from total shots (1.7 extra wins; ±1.0). Effects of most other match events were related to ball possession, which had a small negative within-team effect (1.2 extra losses; ±1.0) but a small positive between-team effect (1.7 extra wins; ±1.4). Game location showed a small positive within-team effect (1.9 extra wins; ±0.9). In analyses of nine combinations of team and opposition end-of-season rank (classified as high, medium, low), almost all between-team effects were unclear, while within-team effects varied depending on the strength of team and opposition. Some of these findings will be useful to coaches and performance analysts when planning training sessions and match tactics. 相似文献

The paper analyzes five historical fictions for children in the Batang Historyador (Young Historian) series which detail five
periods in Philippine history. The books discuss the issues of child labor in precolonial Philippines, child labor and the
right to education regardless of gender during the Spanish colonial period, child labor during the American Occupation, children
as witnesses of history in the Japanese Occupation and Martial Law periods. The narratives reveal (consciously or unconsciously)
how distortedly and inaccurately the past is told from the perspective of a colonized mind. The struggles of historians to
review and revision history from a pro-Filipino consciousness were totally unheeded. The works attempt to throw light on issues
of class, gender and children’s rights but Filipino issues regarding culture, identity, politics and history were obliterated
because the framework was tied to a “universal” notion of history.

Distracted driving is a problem on U.S. roadways. Strategic campaigns have tried to curb this behavior with varying success. Researchers are examining how distracted-driving simulators might be useful in helping to combat this epidemic. Participants (N = 193) took part in a pretest/posttest, between-subjects field experiment where they were randomly assigned to one of five video game driving simulation scenarios (e.g., texting/talking/two combo conditions/distraction-free). Results indicated that participants texting during simulation committed more crashes, fog line crossings, and speed infractions than those talking and those who were not distracted. Further, results indicated that the simulation experience led to reports of being less likely to drive distracted in the future. 相似文献

Educational privatisation has received increasing scholarly attention in recent decades. In much of this work, educational privatisation is viewed as the outcomes of certain government policies or as the result of the influences of education businesses in school systems. This article presents a portrait of an educational entrepreneur in Cambodia to show how privatisation has been enacted by individuals. The empirical data for this article were collected between February and May 2014 using classroom observations and in-depth interviews. The method of portraiture was employed to understand educational privatisation through the perspective of the research subject while embracing the subjective nature of interpreting findings by the researcher. This article develops the literature on educational privatisation by offering a detailed look at the way in which historical memory shapes the behaviour of individuals. This analysis shows how educational privatisation is not only a process of government policy but also a social practice. 相似文献

A common perception exists in the media that university instructors are a liberal elite who use their positions to instill a biased perspective in their students. Exploring student attitudes in the United States and Australia, the present study examined how students’ academic beliefs are related to their inferences of instructor ideological bias and the degree to which they identify as reacting to these inferences in the college classroom. Results of regression analysis using previously validated survey instruments revealed that students’ academic entitlement and grade orientation (GO) predicted perceptions of instructor bias. In addition, students’ GO predicted students’ reactions to such inferred bias. Institutional differences, pedagogical implications, and areas for future research are discussed. 相似文献

Objective
Analysis of the validity and implementation of a child maltreatment actuarial risk assessment model, the California Family Risk Assessment (CFRA).Questions addressed
(1) Is there evidence of the validity of the CFRA under field operating conditions? (2) Do actuarial risk assessment results influence child welfare workers’ service delivery decisions? (3) How frequently are CFRA risk scores overridden by child welfare workers? (4) Is there any difference in the predictive validity of CFRA risk assessments and clinical risk assessments by child welfare workers?Method
The study analyzes 7,685 child abuse/neglect reports originating in 5 California counties followed prospectively for 2 years to identify further substantiated child abuse/neglect. Measures of model calibration and discrimination were used to assess CFRA validity and compare its accuracy with the accuracy of clinical predictions made by child welfare workers. The extent of use of an override feature of the CFRA and child welfare worker reliance on CFRA risk scores for making service decisions were analyzed.Results
Imperfect but better-than-chance predictive validity was found for the CFRA on a range of measures in a large temporal validation sample (n = 6,543). For 114 cases where both CFRA risk assessments and child welfare worker clinical risk assessments were available, the CFRA exhibited evidence of imperfect but better-than-chance predictive validity, while child welfare worker risk assessments were found to be invalid. Child welfare workers overrode CFRA risk assessments in only 114 (1.5%) of 7,685 cases and provided in-home services in statistically significantly larger proportions of higher- versus lower-risk cases, consistent with heavy reliance on the CFRA.Conclusions/practice implications
Until research identifies actuarial models exhibiting superior predictive validity when applied in every-day practice, the CFRA is, and will be a valuable tool for assessing risk in order to make in-home service-provision decisions. 相似文献88.
The purpose of this study was to quantify the relationship between changes in test measures and changes in competition performance for individual elite swimmers. The 24 male and 16 female swimmers, who were monitored for 3.6 years (s = 2.5), raced in a major competition at the end of each 6-month season (3.6 competitions, s = 2.2). A 7 x 200-m incremental swimming step-test and anthropometry were conducted in up to four training phases each season. Correlations of changes in step-test and anthropometry measures between training phases and seasons with changes in competition performance between seasons were derived with repeated-measures mixed-modelling and linear regression. Changes in competition performance were best tracked by changes in test measures between taper phases. The best single predictor of competition performance was skinfolds for females (r = -0.53). The best predictor from the step-test was stroke rate at a blood lactate concentration of 4 mmol x l(-1) (females: r = 0.46; males: r = 0.41); inclusion of the second-best step-test predictor in a multiple linear regression improved the correlations (females: r = 0.52 with speed in the seventh step included; males: r = 0.58 with peak lactate concentration included). In conclusion, a combination of fitness and technique factors is important for competitive performance. The step-test is a useful adjunct in a swimmer's training preparation for tracking large changes in performance. 相似文献

Abstract For this study, we investigated the effects of self-controlled practice on learning multiple motor skills. Thirty participants were randomly assigned to self-control or yoked conditions. Participants learned a three-keystroke pattern with three different relative time structures. Those in the self-control group chose one of three relative time structures before each of 90 practice trials; yoked participants were not allowed to choose but were yoked to a self-control participant and followed that individual's sequence of practice trials. Results of the 24-hr serial transfer test revealed the self-control group exhibited significantly lower relative timing error, absolute error, and total error than the yoked group. Findings further support the efficacy of self-controlled learning. 相似文献

This paper provides an external, international assessment of The Open University, United Kingdom. It questions whether The Open University of the early 1970s is dead and perhaps — in the context of the current emphasis on open learning — invites staff of other open universities throughout the world to anticipate their future five or ten years hence. 相似文献
