Effect of a pilot multi-component intervention on motor performance and metabolic risks in overweight/obese youth

This study evaluated the effect of a multi-component intervention on motor performance (MP) and metabolic risk markers (MRM) in overweight/obese youth. A secondary aim was to examine whether changes in MP are associated to changes in MRM. A 3-month multi-component intervention was performed, consisting of physical exercise sessions (twice/week;1h), nutritional education sessions (once/month), and parental support (twice/week). The sample included 35 volunteers (7–13 y.o), allocated to intervention (INT, n = 17) and control (CONT, n = 18) group. Variables were measured pre (T0) and post intervention (T1). Fasting blood samples were analyzed for MRM. MP tests included the measurement of health related physical fitness components and motor coordination performance (KTK battery). To assess food intake, a 24-hour recall diary was used. GLM-ANCOVA was performed. Standardized scores were calculated for the outcome variables, and multilinear regressions were applied to analyze associations between the key variables. INT group showed improvements in MP, glycolytic and hepatic profiles. After adjustments for MVPA, SB, total intake and maturational stage, negative associations between %ΔMP and %Δglycolytic (β = -.424; 95%CI:-0.343:-0.022), and %Δhepatic scores (β = -.382 95%CI:-0.001:-0.009) were observed. The intervention produced a moderate-to-high effect on the MP and some MRM. Changes in MP were inversely associated with changes in glycolytic and hepatic markers.     

Developing and sustaining an educative mentoring model of STEM teacher professional development through collaborative partnership

In this paper, we present details of a partnership undertaken by four universities with field-based, alternative STEM teacher preparation programs and a large urban school district to provide ongoing professional support for teachers serving as mentors for individuals preparing for careers in high-poverty schools. We also present key findings related to our implementation of an educative mentoring professional learning community (PLC) as a professional development (PD) model for these mentors. Our analysis reveals that mentors as well as candidates identified the PD program as addressing their specific interests and concerns, and that they were regularly and deeply engaged with key activities that were part of each session’s agenda. These findings signal how key elements of PD workshops can contribute to creating and sustaining a local but replicable PLC utilizing an educative mentoring model to support mentors and the future teachers whom they support.     

Impact of interdisciplinary learning on the development of engineering students’ skills

ABSTRACT

This paper intends to present an interdisciplinary project carried out in a School of Engineering, and to refer to its effects in the development of students’ skills. This project’s main goal was to present students with an intellectually demanding challenge which implied overcoming the disciplinary barriers thus integrating knowledge to solve the problems they were challenged with. After the project had been concluded, a study was carried out using a qualitative methodology by conducting two focus groups (n?=?16). The main goal of this procedure was to get a better perception of (1) how students understood the project; (2) what kind of skills students considered to have developed throughout the project, and (3) the importance they have attributed to this kind of project. The results demonstrate that students are aware of the relevance of the project not only for their education process but also for the development of their skills. The results of the study also reveal that the students involved in the project have been capable of identifying the specific skills that the project work had intended to address and develop.

Environmental Education through Hiking: a qualitative investigation

The increasing popularity of outdoor activities, especially hiking, indicates that people are looking for new ways to interact with the natural environment. Hiking could play a role in environmental education by exposing people to cases of environmental deterioration and so raise an awareness of environmental problems. The contribution of hiking in developing a basic understanding of the environment and its problems could result in feelings of concern that lead to active involvement in resolving environmental issues. A qualitative investigation was carried out which involved the completion of three 5 day trails by the same five subjects. Each hiker was required to make daily notes on each hike, which were subsequently analysed. The purpose of the investigation was to ascertain what people notice in the environment during hikes and whether this could influence environmental education. Four themes were identified on analysis of the daily responses, namely the natural and physical environment, trail aspects, each hiker's physical and psychological preparedness and cognitive development and social aspects ranging from group interaction to human impact on the environment. Each of these themes is described and supplemented with appropriate quotations from the daily responses.     

A role of team and organizational identification in the success of cause-related sport marketing

As sport marketers are increasingly engaging in cause-related sport marketing (CRSM) programs, there is a growing interest in understanding what CRSM characteristics and circumstances can lead to success. This study extends prior research by examining the direct and moderating impacts of team identification and cause organizational identification on consumer attitudes toward cause related sport marketing (CRSM) programs using intercollegiate sport contexts in the United States. A two groups (high vs. low-fit CRSM messages), between subject, and post-test only experiment (N = 309) denoted that respondents showed more positive attitudes toward high-fit CRSM messages and both team identification and cause organizational identification had different moderating effects of sport/cause fit on attitudes. Fit between a sport team and a cause had a greater impact on attitudes when consumer affinity toward the sport team was more positive. However, fit had little or no impact when consumer affinity toward the cause was positive, but it played a significant and positive role when consumers showed low affinity toward the cause.     

Intelligence assessment: Gardner multiple intelligence theory as an alternative

In the multiple intelligence framework, newer and more contextualized cognitive tasks are suggested as alternative to more traditional psychometric tests. The purpose of this article is to examine whether or not these two types of instruments converge into a general factor of cognitive performance. Thus, the Battery of General and Differential Aptitudes (BADyG: reasoning, memory, verbal aptitude, numerical aptitude and spatial aptitude) and a set of Gardner's multiple intelligence assessment tasks (linguistic, logical, visual/spatial, bodily-kinesthetic, naturalistic and musical intelligences) were administered to 294 children aged 5 to 7. The confirmatory factor analysis points out the absence of a common general factor considering both batteries, indicating instead the existence of two general factors, which gather the tests that encompass them. Also, these two general factors correspond to traditional and multiple intelligence assessments and show a statistically moderate correlation between them. These results challenge Gardner's original position on refusing a general factor of intelligence, especially when considering the cognitive dimensions measured which do not coincide with the more traditional tests of intelligence.     

Home advantage in judo: A study of the world ranking list

Abstract

In 2009, the International Judo Federation established a ranking system (RS) to classify athletes and to distribute the competitor quotas of the Olympic Games. However, the RS does not consider the home advantage. This issue has not been studied in judo, and its implications for the RS have not been determined. The objective was to verify the home advantage in judo in terms of winning a medal or the number of matches won. Therefore, 25 competitions that computed points for the RS in 2009 were analysed. Logistic regression analysis and the Poisson generalised linear model were used for the analyses, which included the relative quality of the athletes. The sample was composed only of athletes who had competed both at home and away. The odds ratio for winning medals was higher for athletes who competed at home for both males and females. The association between the number of matches won and competing at home was significant only for the male athletes. The home advantage was observed in the competitions that used the judo RS. Thus, it is likely that athletes from countries that host competitions using the RS have an advantage in terms of obtaining their Olympic classification.
