Fit for life : older women`s commitment to exercise

The article explores the lived experiences of older women with a high commitment to exercise. The methods of investigation were in-depth interviews with 17 women fitness instructors for the over-50s and the author's observations as a participant in a variety of exercise programs. The subjective experience of embodiment of older women, the ways in which the body is constructed discursively, and the objective processes of aging are explored. The women's narratives are placed in the wider context of consumption, lifestyle, and identity construction. The study analyzes whether older women's commitment to exercise is a reflection of a climate of constraint, in which individuals seek to shape and manage the body to combat the effects of aging, or is one of empowerment and enablement. More important, the article explores the ways in which the women used fitness programs as a means of constructing intimacy, a sense of community, and satisfaction in interpersonal relations.

Organisational commitment of accountants in Australia and South Africa

This paper examines the independent variables of perceived environmental uncertainty (PEU) and the cultural beliefs of collectivism/individualism between two countries, Australia and South Africa. These countries were chosen because Australia is a stable democracy and South Africa is an emerging democracy which is undergoing significant political, social and economic transformation. The purpose of this paper is to determine whether accountants' commitment to an organisation is associated with perceived environmental uncertainty, collectivism and nationality.

The results of this study suggest that individuals' organizational commitment is associated with nationality (South African and Australian) and that relationship is associated with their cultural beliefs (collectivism/individualism) and an environmental variable, perceived environmental uncertainty.

This research is regarded as important in that multi-national organisations operating in different political and social environments may choose to use different means to ensure the maximum organisational commitment from their employees, in particular, those who are professional accountants.

Casitas b-lineage lymphoma-deficient mice are pretected against high-fat diet-induuced obesity and insulin resistance

Casitas b-lineage lymphoma (c-Cbl) is a multiadaptor protein with E3-ubiquitin ligase activity involved in regulating the degradation of receptor tyrosine kinases. We have recently reported that c-Cbl^–/– mice exhibit a lean phenotype and enhanced peripheral insulin action likely due to elevated energy expenditure. In the study reported here, we examined the effect of a high-fat diet on energy homeostasis and glucose metabolism in these animals. When c-Cbl^–/– mice were fed a high-fat diet for 4 weeks, they maintained hyperphagia, higher whole-body oxygen consumption (27%), and greater activity (threefold) compared with wild-type animals fed the same diet. In addition, the activity of several enzymes involved in mitochondrial fat oxidation and the phosphorylation of acetyl CoA carboxylase was significantly increased in muscle of high-fat–fed c-Cbl–deficient mice, indicating a greater capacity for fat oxidation in these animals. As a result of these differences, fat-fed c-Cbl^–/– mice were 30% leaner than wild-type animals and were protected against high-fat diet–induced insulin resistance. These studies are consistent with a role for c-Cbl in regulating nutrient partitioning in skeletal muscle and emphasize the potential of c-Cbl as a therapeutic target in the treatment of obesity and type 2 diabetes.

A measure of 'high commitment organisation' performance values in sport management professionals and sport organisations

Many organizations have realized the growing importance of adopting a 'High Commitment Organization' (HCO) approach with a focus on shared values to assist them in meeting their competitive challenges. A survey questionnaire based on the McDonald and Gandz (1992) list of values, employing confirmatory and principal components analyses was used to create scales to (a) explore the importance the sport management professional placed on those values, (b) explore the individual's perception of the importance placed on those values by their employing organization, (c) to compare these hierarchies with the values of the HCO, and (d) to measure the extent of value congruence. Three clear sets of values emerged: Development / Adhocracy (D/A) Values, Humanistic / Clan (H/C) Values and Conformity / Hierarchy (C/H) Values. Findings indicate significant differences between sport management professionals' values and those of their organizations. Employees placed higher importance on (D/A) and (H/C) Values than their organizations, while Sport organizations placed higher importance on (C/H) Values than their employees. There is stronger support by individuals than organizations for the values underpinning the HCO approach. These levels of individual - organizational value incongruence have implications for individual job satisfaction, motivation and organizational effectiveness.

An analysis of the involvement-commitment relationship across product categories

An involvement-commitment-loyalty model is proposed and tested with AMOS. The results for fast-moving-consumer-goods (fmcg) are consistent with the theory. Ego involvement influences purchase involvement, which influences brand commitment, which influences customer loyalty. The results for the more ego-involved service of hair stylists, however, showed a different result. Purchase loyalty did not mediate the relationship between ego involvement and brand commitment, but instead ego involvement had a direct relationship with brand commitment.

Organisational commitment of financial planners in Australia

The purpose of this paper is to determine whether the demographic variables of age, gender and length of service can be shown to be related to the organisational commitment (OC) of financial planners in Australia. The financial planners were surveyed using an instrument derived from established questionnaires. It was mailed nationally to 312 financial planners. A response rate of 36% was achieved, equating to 113 useable responses. The analyses revealed statistically significant results at the 90% confidence level (p=0.10), that respondents over the age of 35 demonstrated a significantly higher level of OC than did those under the age of 35, and at the same level of confidence, females demonstrated a statistically significant higher level of OC than did their male counterparts.

Such findings contribute to our understanding of the organisational commitment of Financial Planners, and have implications for employers in terms of hiring and retention of employees. The analyses are also important from a public policy perspective in an era of increasing attention given to, and likely increased regulation of, the financial planning industry.
