Why older Australians participate in exercise and sport

Research on variables that encourage older adults to exercise is limited. This study was carried out to identify the participation motives of older Australians involved in regular exercise and sport. The 815 participants (399 men, 416 women) ranged in age from 55 to 93 years (M = 63.6, SD = 7.8) and were participating in their activities of choice at least once per week. All participants completed the Participation Motivation Questionnaire for Older Adults. The most common exercise/sport activities that participants were involved in were walking, golf, lawn bowls, tennis, and swimming. The most highly reported motives for participation were to keep healthy, liking the activity, to improve fitness, and to maintain joint mobility. Principal-components analysis of the questionnaire revealed 6 factors: social, fitness, recognition, challenge/benefits, medical, and involvement. Analyses of variance showed significant differences in reasons for participation in exercise and sport based on gender, age, education level, and occupation.     

Physical activity and psychological distress in older men: findings from the New South Wales 45 and up study

Physical activity is an important factor in healthy aging and has been shown to reduce depressive symptoms. This association, however, is relatively understudied in older men. This study was a cross-sectional analysis of the association between physical activity (Active Australia Survey) and psychological distress (Kessler-10). Participants were a sample of 17,689 men age ≥ 65 yr drawn from a large-scale Australian cohort study of people age 45 years and over (The 45 and Up Study). The likelihood of reporting high or very high levels of psychological distress decreased with increasing weekly sessions of physical activity. Compared with participants reporting no sessions of physical activity, the fully adjusted odds ratio for high or very high psychological distress was .66 (95% CI .51-.85) for men who undertook 1-6 sessions of physical activity per week and decreased to .57 (95% CI, .43-.79) for men who reported 16 or more weekly sessions. The cross-sectional findings show that older men who are more active are less likely to report psychological distress, regardless of their level of functional limitation. Further research, informed by these findings, is required to investigate causal pathways and the temporal sequence of events.     

Nationalism in Western art music: a reassessment

Nationalism in Western art music has long been a source of intense controversy. Scholars have struggled to provide an adequate definition of the phenomenon with varying degrees of success; principally because it has always been assumed that the national in music must include purely musical elements in its definition. This assumption has led to often grossly inadequate ideas about how nationalism in music is created by a composer and perceived by a listener. A brief review and reassessment of traditional attempts to define nationalism in music may shed new light on the aesthetic realties of the national in music.     

The time-varying performance of the long-run demand for money in the United States

This article investigates the issues of the stability and predictability and interest-sensitivity of money demand over 1870–1997. Two different estimation methodologies are used - random coefficient (RC) modeling and vector error correction (VEC) modeling. The former procedure allows the profiles of the coefficients to be traced over time and relaxes several restrictions routinely imposed in applied work. The results indicate that different estimation methodologies using different data periods and frequencies yield estimates of some of the coefficients of the long-run demand for money that fall within a fairly narrow range. The results also suggest that specification errors have had an important influence on the time profile of the interest elasticity of money demand and that there is a tendency for the interest elasticity to decline in absolute value as interest rates decline.
