Factors associated with exercise participation in adults with arthritis

Most people with arthritis are not regularly active. Understanding what factors influence exercise is essential for designing programs to increase participation. The objective of this study was to examine the correlates of exercise in people with arthritis. Using a cross-sectional design, sociodemographic, health-related, and psychosocial variables were collected from community-dwelling individuals with arthritis (N = 141). Associations with exercise level were examined with bivariate statistics (ANOVAs, chi-squares) and logistic-regression analyses. Exercisers were less likely than nonexercisers and insufficiently active people to report that arthritis negatively affected their physical and social functioning, and they reported more positive affect and greater self-efficacy (p < .05). Exercisers also reported less pain than nonexercisers (p < .05). In multiple logistic-regression analyses, self-efficacy and physical limitations remained independent predictors of exercise. The results suggest the need to target exercise self-efficacy when designing exercise interventions. Results also suggest the need to tailor exercise programs to individuals' physical limitations.     

Methodology and analysis for comparing discrete linear l1 approximation codes

This is the first of a projected series of papers dealing with computational experimentation in mathematical programming. This paper provides early results of a test case using four discrete linear L₁ approximation codes. Variables influencing code behavior are identified and measures of performance are specified. More importantly, an experimental design is developed for assessing code performance and is illustrated using the variable “problem size”.     

Some Australian Children's Perceptions of Physical Punishment in Childhood

Despite ratification of the United Nations Convention on the Rights of the Child, children remain the only people in Australia against whom violence may be justified as discipline. This article presents findings from qualitative research conducted in the State of Victoria, in which children were invited to contextualise incidents of physical punishment by describing the experience from different standpoints and reflecting on the feelings and motivations of victims and perpetrators. The research provides new insights into children's experiences of childhood ‘discipline’, as children reveal the physical and emotional impact of being hit by a parent, the futility of ‘physical punishment’, parents’ confusing reactions and children's awareness of double standards. Children suggest more positive ways to communicate and to resolve conflict, and provide insightful comments that have the potential to enlighten adults’ thinking about the issue.     

Employee attitude surveys: Their interpretation and use

This paper evaluates the uses of attitude surveys as a guide to management decision-making and identifies some of the problems of carrying out such studies and implementing the results. The concepts of attitude, value, personality, motivation, morale and job satisfaction are reviewed and their relevance discussed. A model of the determinants of attitudes is developed and used as a basis for a consideration of the problems of effecting change and increasing job satisfaction. Finally, the types of action that might be recommended on the basis of attitude survey data are considered and the roles of management and researchers in the interpretation and implementation of conclusions discussed.     

College Expectations of Rural Appalachian Youth: An Exploration of Social Cognitive Career Theory Factors

An examination of social cognitive career theory (SCCT; R. W. Lent, S. D. Brown, & G. Hackett, 1994, 2000) factors contributing to the college expectations of high school students (N = 87) in rural Appalachia was conducted. Hierarchical multiple regression analyses revealed support for the role of SCCT variables in predicting expectations to attend college. Specifically, the SCCT variables of perceptions of parental support and self‐efficacy beliefs independently predicted Appalachian youth's expectations to attend college. Results are discussed in relation to SCCT, and implications for counseling and future research are presented.
