Abstract

Since its establishment in the early 1950s, the Greek Extension Service has undergone considerable changes. Especially after 1981, a bureaucratic–administrative role related to the implementation of the CAP has been undertaken. In parallel, in the international scene, governments have started experimenting with various cost-recovery mechanisms for extension. In front of such challenges, at both national and international levels, the current work intends to explore the willingness of young rural inhabitants to pay for advisory services. Drawing data from a large-scale survey and utilising probit analysis, the decomposition of the marginal effects of a series demographic, socioeconomic and spatial characteristics and information needs upon willingness to pay for extension is presented. The results show that under preconditions cost-recovery mechanisms may be employed in Greece; furthermore, it is argued that the Extension Service has to be restructured–reoriented.  相似文献

It is well documented that government agencies, at all levels, continue to have problems ensuring that government web sites follow laws related to web accessibility for people with disabilities. Although there are a number of published studies on government web accessibility that are point-in-time, there are no published studies consisting of a longitudinal analysis of state-level government web site accessibility. This paper contributes to the research literature in three ways: 1) an accessibility inspection of 25 Maryland state government homepages in 2012 which involved 150 human inspections of web pages, 2) a comparison of the results from 2012 to a similar accessibility evaluation in 2009, and 3) a discussion of the role of a web page template, which was introduced in Maryland state government shortly after the 2009 evaluation. The data from this longitudinal evaluation leads to the conclusion that web page templates do tend to result in more accessible sites within state government.  相似文献

A large percentage of the students who drop out of K–12 schools in the United States do so at the end of high school, at some point after grade 10. Yet little is known about the differences between types of students who drop out near the end of high school. The purpose of this study is to examine a typology of high school dropouts from a large nationally representative dataset (ELS:2002) using latent class analysis (LCA). We found three significantly different types of dropouts; Quiet, Jaded, and Involved. Based on this typology of three subgroups, we discuss implications for future dropout intervention research, policy, and practice.  相似文献

Abstract

This study aimed to investigate the direct and indirect associations between perceived environmental characteristics and psychosocial factors and physical activity levels in adolescents from Northeast Brazil. The sample was composed of 2,361 adolescents aged 14–19 years (56.6% female). Physical activity was measured using a questionnaire and environmental (perceived environmental characteristics) and psychosocial (self-efficacy, social support from parents and friends for physical activity) factors with previously validated scales. Perceived environmental characteristics were not directly associated with the levels of physical activity, but exhibited significant indirect associations, mediated by self-efficacy in males. Self-efficacy and social support were positively and directly associated with physical activity levels, and part of the associations between social support and physical activity was mediated by self-efficacy. Perception of self-efficacy and social support, important factors associated with physical activity levels in adolescents, should be the target of interventions aimed at increasing physical activity. Favorable environments for physical activity also need to be considered, since they have a positive influence on the self-efficacy of adolescents.  相似文献
