Discrepancies in accelerometer-measured physical activity in children due to cut-point non-equivalence and placement site

Abstract This study examined dissonance in physical activity (PA) between two youth-specific hip-derived intensity cut-points for the Actiwatch (AW), and compared PA between hip and wrist placements using site-specific cut-points. Twenty-four children aged 11.2?±?0.5 years wore the AW on the right hip and non-dominant wrist during a typical school day. Minutes of sedentary behaviour and vigorous activity were greater using Puyau et al. (2002) cut-points, but light, moderate, and moderate-to-vigorous (MVPA) were greater when derived using Puyau et al. (2004) cut-points (P?相似文献   

Agricultural extension in South-Eastern Europe: Issues of transition and sustainability

Following the economic reforms in the early 90's, most of the south-eastern European countries (SEE) made efforts to establish agricultural extension services. However, a number of factors including tight governmental budgets, lack of experience, and the existence of vested interests have constrained the development of extension services. This paper examines the rationale for public funding of extension programs and evaluates the incentive structure for private and public provision of agricultural extension service in the SEE countries. It suggests a medium and long-term approach with a primary focus on institutional design. Two groups of factors that affect the private sector supply of extension are analyzed: (i) demand and supply-side factors that affect the profitability of the service and (ii) factors arising from the public-good nature of extension output, externalities, and moral hazards that affect the appropriation of returns of the service. The main conclusion is that the SEE countries should try to achieve a public-private extension balance by following a gradual approach toward privatization of the agricultural extension service. However, the paper advocates a continued important role for the public sector to correct for potential undesirable effects of private advisory services.     

COMPARISON OF THE BECK DEPRESSION INVENTORY-II AND THE INVENTORY TO DIAGNOSE DEPRESSION: IMPLICATIONS FOR COMMUNITY COLLEGE COUNSELORS

Community college counselors need to assess depressive symptoms in students and to differentiate depressive symptoms from anxiety symptoms to help them implement crisis intervention strategies. Two instruments available to the community college counselor are the Beck Depression Inventory-II (BDI-II) and the Inventory to Diagnose Depression (IDD). This article, which is based on the published literature, reports on and discusses the construct and discriminant validities of the BDI-II and IDD so that community college counselors may use them with knowledge of the strengths and weaknesses of each instrument. Although results should be interpreted with caution, both instruments are useful in measuring the presence or absence of depressive symptoms.     

A Longitudinal View of the Liberal Arts Curriculum a Decade After Merger: A Multiple Case Study of Community Colleges in Connecticut,Kentucky, and Louisiana

This study is an examination of the state of the liberal arts curriculum in community colleges in three geographic regions of the United States. From a constructivist paradigm and using globalization theory as a theoretical framework, this multiple case study examined faculty work life and administrative processes related to curriculum change in merged community and technical colleges. Through an examination of research on globalization, mergers, and trends in the general education and liberal arts curriculum, a gap in the literature emerged in the studies of community college curriculums after merger. This study considers whether the focus on workforce development and decrease in the transfer mission has diminished the liberal arts courses in the college curriculum. Research on liberal arts courses identified them as courses that emphasize higher order thinking and the development of intellectual skills needed to engage in a democratic society. If students are not exposed to these skills, it may have a detrimental effect on a democratic society. Study findings suggested that the English and communication curriculums are narrowing and the mission is more toward workforce skill preparation. Also, the changing demographics of today[#x02019]s community college students, as well as the ongoing budget constraints, create challenges and frustrations for faculty members.     

Happily Ever After? A Content Analysis of Romantic Ideals in Disney Princess Films

This study presents a quantitative content analysis of the romantic expressions portrayed in the 12 Disney princess movies. The films were analyzed for presence of romantic expressions (ideals and challenges) and the character reactions to those expressions. Results indicated that romantic expressions are prevalent in these films, with idealization of other as the most common ideal expressed. The transitional era of films (i.e., princess movies released between 1989 and 1998) contained roughly the same number of ideals as the other eras of classic (i.e., movies released before 1989) and modern (i.e., movies released after 1998) combined. Further, ideals were three times more common than challenges in classic films, whereas ideals and challenges were expressed equally in transitional and modern films. In general, across all three eras, challenges were most commonly met with punishing and negative reactions, whereas ideals were most often rewarded. Finally, there were no sex differences in terms of ideal expressions, but male characters were the dominant pursuers in 9 of the 11 films that featured a romantic relationship.     

The transfer of U.S. technology abroad

The causes of the transfer of technology between countries is now seen as an important dimension of the diffusion of new products and processes. Despite its obvious importance, there has been little empirical research investigating the international transfer of technology, although the work of Schiffel and Kitti (Research Policy 7 (1978)) provides a useful foundation on which to build. The research reported below tests the hypothesis that the transfer of technology between countries, as measured by the movement of patented invention, is influenced by both supply side and demand side factors. The principal variables are: patenting activity in the country of origin; the size of the recepient economy; international trade in goods and services; and the operations of multinational producing enterprises. These vaiables explain most of the variation across countries in the transfer of U.S. technology abroad. The worldwide distribution of U.S. based multinational enterprises appear to play an important part in explaining U.S. technology tranfer. On the other hand, the remaining international differences in patent law do not seem to significantly affect patent flows between countries.
