Negotiating accommodations so that work-based education facilitates career development for youth with disabilities

Workers with disabilities are entitled to have their individual needs accommodated in a way that allows them to perform the essential duties of their job. However, adults with disabilities are often lacking in career development and are ill-prepared to negotiate workplace accommodations. This has led educators to seek workplaces that can accommodate the needs of adolescents with disabilities, so these adolescents can learn to negotiate accommodations and enhance their career development through work-based education. This paper reports on two case studies in which employers had agreed to accommodate the needs of adolescents with disabilities participating in work-based education. Social Cognitive Career Theory (SCCT) framed the analyses of these two cases - a case of a student with physical disabilities and a case of a student with developmental disabilities. SCCT proves valuable in understanding the role of work-based education in the career development of disabled youth.     

Small Enterprise: Finance, Ownership and Control

Finance, ownership and control issues have received a great deal of attention in recent years as centres of interest in the 'new institutional economics'. Much of the debate has been fuelled by the inability of neoclassical economics to explain the continued existence, and increasing importance, of small enterprises. Developments in agency theory, information asymmetry and signalling theory, and transaction cost economics are identified as contributing to a new approach. The concepts distilled from a review of these developments are then used in the analyses of well-known phenomena involving small enterprises. These include capital structure and access to capital markets featuring the finance gap, the underpricing of new issues and the small firm effect. In addition, going private, by means of management buy-outs, and franchising are examined. It is seen that the economic literature on finance, ownership and control helps to explain both the advantages and disadvantages of small enterprises. Their continued existence is seen as being due to a trade-off of various costs and benefits.     

ON SPLINE SMOOTHING WITH AUTOCORRELATED ERRORS

The generalised cross-validation criterion for choosing the degree of smoothing in spline regression is extended to accommodate an autocorrelated error sequence. It is demonstrated via simulation that the minimum generalised cross-validation smoothing spline is an inconsistent estimator in the presence of autocorrelated errors and that ignoring even moderate autocorrelation structure can seriously affect the performance of the cross-validated smoothing spline. The method of penalised maximum likelihood is used to develop an efficient algorithm for the case in which the autocorrelation decays exponentially. An application of the method to a published data-set is described. The method does not require the data to be equally spaced in time.     

Risky behaviour: a new framework for understanding why young people take risks

Theories of youth risk taking range from the realist to the sociocultural. Much of this theorising, particularly in the field of epidemiology, has been strongly influenced by the Health Belief Framework. More recently, attention has shifted to understanding how young people perceive risk and what makes some of them resilient to risk taking. In this article we develop a framework that brings together diverse theoretical perspectives on youth risk taking. We draw on lessons from across the social science disciplines to inform a conceptual framework incorporating the broad context and internal processes of young people's decisions to take risks. Our Youth Risk Interpretation Framework (Y-RIF) has been developed from insights gained during an ethnographic study conducted in South Africa (Graham, Lauren, 2012. Understanding risk in the everyday identity-work of young people on the East Rand of Johannesburg. Doctoral Thesis. University of Johannesburg, Johannesburg.). We argue that our framework is useful, as it offers new ways of understanding why some young people take risks while others are more cautious. It could be used to inform youth behaviour surveillance research and interventions. However, it will need to be rigorously tested.     

Associations Between Physical Activity and Health-Related Factors in a National Sample of College Students

Abstract

Objective: To examine associations between meeting the current moderate to vigorous physical activity (MVPA) recommendation and health-related factors in a national sample of college students. Participants: Participants (N = 67,861) completed the National College Health Assessment II during the Fall 2008/Spring 2009 academic year. Methods: Hierarchical binary logistic regression was used to examine the contribution of 19 variables in explaining whether or not participants met the MVPA recommendation. Results: Meeting the MVPA recommendation was associated with several protective factors among college students, including adequate daily fruit and vegetable consumption, positive perception of general health, healthy body mass index, consistent seatbelt use, not smoking cigarettes, less perceived depression, and adequate sleep. In addition, meeting the MVPA recommendation was also significantly associated with a few risky behaviors including binge drinking, physical fighting, and multiple sexual partners. Conclusions: College student PA interventions should consider also addressing fruit/vegetable consumption and binge drinking.
