The impact of referee training: reflections on the reduction of home advantage in association football

The effect of increased development and professionalization in elite Association Football referee training and the relationship with reduced home advantage in the English professional leagues were examined. The central aim was to chart the evolution of referee training, and how these developments in referee training have assisted in reducing home advantage. Interviews were conducted with elite and ex-elite referees, as well as those involved in the management, training and administration of elite referees in order to identify more recent adaptations to elite referee training and further explain the relationship between training and the reduction in home advantage. Findings indicate training and support is pronounced within elite refereeing has developed appreciably over time, and has contributed significantly to an increase in performance, decision-making correctness and subsequent decline in home advantage.     

Resources for sports engineering education

This paper serves as a resource guide for Sports Engineering educators. The paper covers key topics in Sports Engineering, including ball impact, friction, safety and materials. A variety of resource types are presented to reflect modern methods of learning and searching for information, including textbooks, research and review papers, websites and videos. The field could benefit from more resources specifically designated for teaching Sports Engineering, particularly textbooks.     

Systems,transfer, and fields: Evaluating a new approach to energy instruction

Energy is a central concept in science in every discipline and also an essential player in many of the issues facing people everywhere on the globe. However, studies have shown that by the end of K-12 schooling, most students do not reach the level of understanding required to be able to use energy to make sense of a wide range of phenomena. Many researchers have questioned whether the conceptual foundations of traditional approaches to energy instruction may be responsible for students' difficulties. In response to these concerns, we developed and tested a novel approach to middle school physical science energy instruction that was informed by the recommendations of the Framework for K-12 Science Education (National Research Council, 2012a) and the Next Generation Science Standards (NGSS) (NGSS Lead States, 2013). This new approach differs substantially from more traditional approaches to energy instruction in that it does not require energy forms and it emphasizes connections between energy, systems, and fields that mediate interaction-at-a-distance. We investigated student learning during this novel approach and contrasted it with student learning within a comparable unit based on a more traditional approach to energy instruction. Our findings indicate that students who learned in the new approach outperformed students who learned in the traditional approach in every quantitative and qualitative aspect considered in this study, irrespective of their prior knowledge of energy. They developed more parsimonious knowledge networks in relation to energy that focused primarily around the concept of energy transfer. This study warrants further investigation into the value of this new approach to energy instruction in both middle and high school.     

An accurate VO2max nonexercise regression model for 18-65-year-old adults

The purpose of this study was to develop a regression equation to predict maximal oxygen uptake (VO2max) based on nonexercise (N-EX) data. All participants (N = 100), ages 18-65 years, successfully completed a maximal graded exercise test (GXT) to assess VO2max (M = 39.96 mL x kg(-1) x min(-1), SD = 9.54). The N-EX data collected just before the maximal GXT included the participant's age; gender; body mass index (BMI); perceived functional ability (PFA) to walk, jog, or run given distances; and current physical activity (PA-R) level. Multiple linear regression generated the following N-EX prediction equation (R = .93, SEE = 3.45 mL x kg(-1) x min(-1), % SEE = 8.62): VO2max (mL x kg(-1) x min(-1)) = 48.0730 + (6.1779 x gender; women = 0, men = 1) - (0. 2463 x age) - (0.6186 x BMI) + (0.7115 x PFA) + (0.6709 x PA-R). Cross validation using PRESS (predicted residual sum of squares) statistics revealed minimal shrinkage (R(p) = .91 and SEE(p) = 3.63 mL x kg(-1) x min(-1)); thus, this model should yield acceptable accuracy when applied to an independent sample of adults (ages 18-65 years) with a similar cardiorespiratory fitness level. Based on standardized beta-weights, the PFA variable (0.41) was the most effective at predicting VO2max followed by age (-0.34), gender (0.33), BMI (-0.27), and PA-R (0.16). This study provides a N-EX regression model that yields relatively accurate results and is a convenient way to predict VO2max in adult men and women.     

Children's Views on Quality Standards for Children's Television Programs

Extending a recent study of the standards mothers apply in evaluating the quality of children's programs (Nikken et al., 1996), this study investigated the standards children between 9 and 12 years of age (N = 427) use to evaluate the quality of four types of children's programs: children's news programs, educational programs for children, dramatic programs for children, and cartoons. Data were collected by means of questionnaires. A factor analysis resulted in a list of nine types of quality standards. The two quality standards children considered most important were: (a) comprehensibility, and (b) aesthetic quality. Additional standards were: (c) entertainment, (d) involvement, (e) credibility, (f) innocuousness, (g) restfulness, (h) thought provocation, and (i) presence of role models. The importance children attached to the nine quality standards varied with both program type and child characteristics. Seven of the quality standards found in the present study are similar to the maternal quality standards observed in Nikken et al. ‘s study. The children in the present study generally viewed these seven quality standards as less important than the mothers in Nikken et al.’s study. However, the relative importance children and mothers attached to these quality standards showed similarity, especially in the case of cartoons, and to a lesser extent for children's news programs and dramatic programs.     

The Scottish Dimension

The Report of the Scottish Tertiary Education Advisory Council (STEAC), published in December 1985, has proposed that in the northern part of the United Kingdom there should be an alternative to the binary system of higher education, with both the universities and the public sector being planned for and financially controlled by the same body. That suggestion has been welcomed by many Scottish interests, but has raised fears in the majority of university staff, who see a danger of their being cut off from their counterparts elsewhere in the UK .
This article contends that the fears are not essentially Scottish in nature, and that the greatest danger to universities in any system of joint planning and finding is that the body responsible would be bound to take steps to reduce the inequalities which exist between the two sectors. What STEAC has proposed for Scotland should be considered for England and Wales too; the Scottish situation only presents an easier opportunity to achieve it .
The author is not wholly optimistic however. His analysis of the decisions taken in July 1986 by the Secretary of State for Scotland perceives political lobbying as having been of great influence on the outcome of the recommendations dealt with at that time. He wonders whether politicians will withstand the greater lobbying power of the universities against the main STEAC proposal .
