“Changing the Text”: Modeling Council Capacity to Produce Institutionalized Change

Collaboration is a ubiquitous approach to change, but is notoriously difficult and not definitively linked to desirable outcomes. Not surprisingly, the collaboration literature is replete with numerous facilitators and barriers to collaborative efforts. The current study aimed to develop a parsimonious model of factors influencing the success of collaborative efforts both internal and external to the council, including, (a) features of the council environment, (b) intermediate outcomes including the empowerment of members in the council context and the degree to which councils have generated social capital and (c) the extent to which collaborative efforts are occurring in a community context supportive of their aims. In particular, this study examines whether these factors affect the extent to which councils are positioned to achieve institutionalized change, or changes \"in the text\" that govern front line providers' (e.g., police, advocates) practices in the community response to intimate partner violence. Results suggest that perceived member empowerment, generation of social capital, and supportive community context are the most important predictors of the extent to which councils foster shifts in institutionalized change. Features of the council environment are only indirectly related to the degree to which institutionalized change is ultimately fostered as mediated by the generation of social capital. This suggests that the ability of members to act as change agents and the extent to which those in power support council efforts figure more prominently to facilitate or constrain council efforts than council functioning itself.     

Preventive behaviour and health status among the elderly

Abstract

The research describes the range of preventive health behaviours undertaken by the elderly, investigates the dimensionality of preventive health behaviour, and explores the relationship between preventive health behaviour, self-assessed and medically assessed health status. Previous research has relied mainly on self-reports of health status. Data from medical examinations and interviews with 115 elderly individuals (aged 65–75) indicated that most elderly persons performed some intentional preventive health practices, as well as a broad range of normative preventive health practices. Particular clusters of preventive health behaviour emerged when the data were subjected to cluster analysis. A short index consisting of five personal preventive health behaviours found in other studies to have a protective effect on long-term health was found to have a low to moderate correlation with the medical and self-assessments of health status employed in the study. These findings indicate particular types of preventive health behaviour of importance for health promotion programmes with the elderly.     

Are Older Adults More Dependent on Visual Information in Regulating Self-Motion Than Younger Adults?

Older adults look at the ground more while they are walking than younger adults do. In the present study, the effect of blocking that exproprioceptive visual information on the walking pattern of older adults was investigated. The first 0.75 m of the floor in front of healthy young adults (n = 10, mean age = 26.0 years) and 2 groups of older adults (n = 10, mean age 65.7 years; and n = 9, mean age = 75.9 years) was occluded. The dependent variables were step velocity, step length, and step frequency. The effect of the manipulation on those kinematic variables increased with age. The older adults had a significant increase in velocity and step length. The possible use of optic flow information from the ground to regulate the velocity of self-motion is discussed.     

Undisturbed Upright Stance Control in the Elderly: Part 2. Postural-Control Impairments of Elderly Fallers

A common way of predicting falling risks in elderly people can be to study center of pressure (CP) trajectories during undisturbed upright stance maintenance. By estimating the difference between CP and center of gravity (CG) motions (CP - CG_v), one can estimate the neuromuscular activity. The results of this study, which included 34 sedentary elderly persons aged over 75 years (21 fallers and 13 nonfallers), demonstrated significantly increased CG_h and CP - CG_v motions in both axes for the fallers. In addition, the fallers presented larger CG_h motions in the mediolateral axis, suggesting an enlarged loading—unloading mechanism, which could have reflected the adoption of a step-initiating strategy. As highlighted by fractional Brownian motion modeling, the distance covered by the CP - CG_v motions before the successive control mechanisms switched was enhanced for the fallers in both axes, therefore increasing the risk that the CG would be outside of the base of support.     

Banding Together: New Horizons in Lifelong Music Making

New Horizons Bands are wind and percussion bands designed for both novice and former musicians over the age of 50. This article describes the Iowa City, Iowa, program from the director's observations and from excerpted comments by participants. Not only does the band program fulfill musical aspirations, but it also provides meaningful interpersonal relationships for the adult learners and their families, the college-aged instructors, and the director.     

Personality Changes Associated with Localized Brain Injury in Elderly Populations

Emotional disturbances following brain damage have been frequently reported in the literature. However, systematic investigation of these disorders and their specific causes were not common until the last 30 years. However, the number of research studies into this area remains slight compared to the voluminous literature on the cognitive effects of brain injury. The completed research has fallen into 3 major areas: (1) The study of clients with localized brain injuries to evaluate whether the site of the injury predicts the emotional reactions; (2) the effect of time poststroke on personality changes; and (3) the relation of neuropsychological deficits to emotional changes. This paper provides a comprehensive review of the research that has been completed in this area with elderly subjects along with an analysis of the current state of the knowledge in this area. Future directions for research to further our understanding are discussed.
