Obesity: Analysis of Attitudes and Knowledge of Weight Control in Girls

Abstract

A questionnaire involving attitudes toward obesity, food, and physical exercise, and knowledge about weight control, was administered to 225 obese female adolescents and 213 controls. Results indicated an obsession on the part of the obese with their weight, to such an extent that nonrelated areas became involved in the issue. Despite the greater knowledge of the obese concerning weight control, and their more positive attitudes toward exercise, these factors seemed to have little effect in helping them deal with their obesity.     

Funding, resource allocation, and performance in higher education systems

This article analyzes forms of resourceallocation in university systems and theireffects on performance in institutions ofhigher education. Internationally, highereducation systems differ substantially withregard to research and education fundingsources and to ways that resources areallocated. European universities receive themajority of their funding from public sources,but private funding plays a more important rolein Anglo-American systems of higher education.Many governments use competitive elements inthe process of allocating public funds toinstitutions of higher education. Examplesinclude the implementation of performancemeasures through formula funding, or resourceallocation on the basis of evaluated projectproposals. Corresponding forms ofperformance-based resource allocation can befound within most higher educationinstitutions. This article analyzes how variousforms of funding and resource allocation affectuniversities at the macro-level and individualbehavior at the micro-level. A theoreticalapproach to this problem suggests thatperformance-based funding tends to bring aboutpositive changes but is also a factor inunintended side effects. Forms of resourceallocation influence the behavior of academicsand managers in higher education, particularlytheir levels of activity as well as the kindsof activities they engage in and their ways ofdealing with risks. Empirical analyses partlyconfirm these hypotheses. It can be shown thatchanges in resource allocation have an impacton the level and type of activity academicsconcentrate on but not on the long-term successof universities.     

The sequencing of instruction and the concept of assimilation-to-schema

The concept of assimilation-to-schema proposes that learning depends on three conditions: (1) the reception of the to-be-learned material, (2) the availability of a cognitive structure to which the new material may be assimilated, (3) the activation of the structure during learning. The concept provides weak (i.e., concerning amount of learning) and strong (i.e. concerning the structure of learning outcomes) predictions with respect to the effects of sequencing of instruction, ordering of instruction and organization of instruction. The present review demonstrates that studies of the role of instructional sequencing provide an important test of the assimilation-to-schema theory, and that many apparent inconsistencies in the literature may be better understood by an analysis of the internal assimilation process.This paper was partially supported by a Faculty Research Grant from the Academic Senate of the University of California, Santa Barbara.     

Higher education funding reform and university–industry links in developing countries: The case of Thailand

Most investigations into the effects of funding changes on higher education systems have been carried out in developed economies. This article focuses on the Thai higher education system, applying theoretical arguments and empirical analyses to the case of a newly industrialising country. One goal of the Thai higher education funding reform is to cut public spending and to stimulate university–industry cooperation as a means to obtain additional university income. This article presents empirical data based on an investigation into the cooperation activities of five Thai universities. The results show that both individuals and organisations react to changes in university funding: university–industry relations are becoming more frequent and are promoted by university administrations. The financial benefits for the universities as well as the technological benefits for the cooperating companies are, however, both very limited.     

Effect Analysis Using Nonlinear Structural Equation Mixture Modeling

In this article, we present an approach for comprehensive analysis of the effectiveness of interventions based on nonlinear structural equation mixture models (NSEMM). We provide definitions of average and conditional effects and show how they can be computed. We extend the traditional moderated regression approach to include latent continous and discrete (mixture) variables as well as their higher order interactions, quadratic or more general nonlinear relationships. This new approach can be considered a combination of the recently proposed EffectLiteR approach and the NSEMM approach. A key advantage of this synthesis is that it gives applied researchers the opportunity to gain greater insight into the effectiveness of the intervention. For example, it makes it possible to consider structural equation models for situations where the treatment is noneffective for extreme values of a latent covariate but is effective for medium values, as we illustrate using an example from the educational sciences.     

The myth of global science collaboration—Collaboration patterns in epistemic communities

Scientific collaboration is often perceived as a joint global process that involves researchers worldwide, regardless of their place of work and residence. Globalization of science, in this respect, implies that collaboration among scientists takes place along the lines of common topics and irrespective of the spatial distances between the collaborators. The networks of collaborators, termed ‘epistemic communities’, should thus have a space-independent structure. This paper shows that such a notion of globalized scientific collaboration is not supported by empirical data. It introduces a novel approach of analyzing distance-dependent probabilities of collaboration. The results of the analysis of six distinct scientific fields reveal that intra-country collaboration is about 10–50 times more likely to occur than international collaboration. Moreover, strong dependencies exist between collaboration activity (measured in co-authorships) and spatial distance when confined to national borders. However, the fact that distance becomes irrelevant once collaboration is taken to the international scale suggests a globalized science system that is strongly influenced by the gravity of local science clusters. The similarity of the probability functions of the six science fields analyzed suggests a universal mode of spatial governance that is independent from the mode of knowledge creation in science.     

Basic Approaches

Abstract

Communication abilities, conflict management, and delegation are all important to students' success in the work force. Instructors often simulate situations that give students skills in these crucial areas by assigning group projects. It is often difficult for instructors to select individuals who will work successfully together. Common methods for selecting groups, many of which are ineffective, are discussed. A student self-assessment method used by the authors to group students according to their skills is described. The method, used for two years in both sophomore-and senior-level courses, has been proven to prevent intragroup skill imbalances.
