This study evaluates home advantages both for national (Super 12) and international (Tri-nations) rugby union teams from South Africa, Australia and New Zealand, over the five-year period 2000 - 2004 using linear modelling. These home advantages are examined for statistical and practical significance, for variability between teams, for stability over time and for inter-correlation. These data reveal that the overall home advantage in elite rugby union has a mean of +6.7 points, and that this changes little from year to year. Closer scrutiny nevertheless reveals a high degree of variability. Different teams can and do have different home advantages, which ranges from a low of -0.7 to a high of +28.3 points in any one year. Furthermore, some team home advantages change up or down from one year to the next, by as much as -36.5 to +31.4 points at the extremes. There is no evidence that the stronger teams have the higher home advantages, or that a high home advantage leads to a superior finishing position in the competition. 相似文献

ABSTRACTSeldom have comparative studies of educational assessment systems been undertaken, especially regarding their standard setting procedures. This study examines the effects of governance structures on the power relations in standard setting in the dominant school-leaving or university-entrance examinations. We present acritical analysis of the published research and policy documents, including sense-checking with senior assessment practitioners from 22 jurisdictions. The nature of standard setting systems in three cases of Ireland, the USA and India are described in detail to showcase the differences between the following three models of governance systems: nationalised, commercial market and quasi-market. The contribution of this article, then, is to describe the three models of governance systems, to classify the 22 jurisdictions using the three models, and to generate propositions inductively. Thus, the article provides aconceptual basis for extension of this work to other cases to advance the literature cumulatively by theory-building. 相似文献

An attempt was made to train 9 homing pigeons to respond to the presence or absence of bar magnets by turning either left or right after flying the length of a 20-ft outdoor flight cage. During initial training, color cues were placed in front of feeding stations on the left and right sides of the cage. The color cues were paired with magnetic cues by attaching either bar magnets or brass bars to the backs of the birds. The color cues were then deleted, leaving only the magnetic cues. Each pigeon received about 300 trials of color training followed by about 200 trials of magnet testing. When only magnetic cues remained, none of the pigeons were able to choose the correct feeder at greater than chance levels of probability. 相似文献

Subgrouping poor readers on the basis of individual differences in reading-related abilities 总被引:1,自引:0,他引:1
The present study investigated the use of the Reading Component Model to subgroup poor readers. A large sample of poor readers was identified in second grade and subgrouped on the basis of relative strengths and weaknesses in word recognition and listening comprehension. Although homogeneous subgroups were not identified, poor readers could be classified into four subgroups that differed significantly in reading-related abilities. Further analyses showed that poor readers' strengths and weaknesses in listening comprehension, and to a lesser extent in word recognition, were foreshadowed by their abilities on related kindergarten measures. Follow-up testing in the fourth grade indicated that poor readers' individual differences in word recognition and listening comprehension were consistent and that subgroups were moderately stable. The implications of these results for the assessment and remediation of reading disabilities are discussed. 相似文献
