Investing: the case for recognition as an independent capacity

In this article, we provide support for the need to recognize investing as an independent capacity. A comparison of the definitions and models of financial and investing capacities revealed significant differences between them. A review of the status of investing capacity assessment revealed that there are currently no investing capacity specific assessment instruments (ICSAIs). Implications for researchers and clinicians resulting from the lack of recognition of investing as an independent capacity are discussed and used as a rational for the need to develop ICSAIs. The benefits of ICSAI development for financial, legal, and clinical professionals as well as for investors are discussed, and a direction for future investing capacity research is proposed.     

Effects of vibration exercise on muscle performance and mobility in an older population

This study was designed to investigate the effects of vibration on muscle performance and mobility in a healthy, untrained, older population. Forty-three participants (23 men, 20 women, 66-85 y old) performed tests of sit-to-stand (STS), 5- and 10-m fast walk, timed up-and-go test, stair mobility, and strength. Participants were randomly assigned to a vibration group, an exercise-withoutvibration group, or a control group. Training consisted of 3 sessions/wk for 2 mo. After training, the vibration and exercise groups showed improved STS (12.4%, 10.2%), 5-m fast walk (3.0%, 3.7%), and knee-extension strength (8.1%, 7.2%) compared with the control (p < 0.05). Even though vibration training improved lower limb strength, it did not appear to have a facilitatory effect on functional-performance tasks compared with the exercise-without-vibration group. Comparable mobility and performance changes between the experimental groups suggest that improvements are linked with greater knee-extension strength and largely attributed to the unloaded squats performed by both exercise groups.     

Management of Parkinson's disease in older women

Elderly women with Parkinson's disease (PD) represent a specific patient population that may benefit from individualized treatment strategies. PD has been shown to occur approximately twice as often in men than in women, resulting in theories regarding estrogen being protective against the disease and as a potential treatment strategy. Given women's longer life expectancy, they are more likely to reach an age where antiparkinsonian medications are associated with side-effects. This paper will review medical and surgical treatments as well as the relationship of gender and age with respect to the management of PD.     

Community research on older women in the Dominican Republic

This article looks at action research into the interests and needs of older women in 11 urban communities in Santo Domingo, Dominican Republic. Since 1993, Aquelarre has been working in Santo Domingo with the goal of ending child abuse and violence against women in the home, promote good health among women, and the well-being of older women. In order to achieve these goals, an action research was conducted. Individual interviews with 70 older women, focus group sessions with 120 women, and interviews with key community members were carried out to elicit information on older women's interest and needs. The research was able to identify the major concerns among women, which are health, economic issues, education and family. Practical solutions to these problems were then developed. Throughout the research, it was noted that there was a tendency for participants to focus on the needs of their loved ones, rather than their own needs and problems.     

Effects of multicomponent training on functional fitness in older adults

The purpose of this study was to evaluate the effects of a 9-week supervised multicomponent exercise program on functional fitness and body composition in independent older adults. Forty-two adults age 60-86 years were randomly assigned to an exercise or a control group and were evaluated before and after training. The training program consisted of 3 sessions of walking, strengthening, and flexibility exercises per week. The multicomponent training program resulted in significant (p < .005) improvements on the chair stand, arm curl, 6-min walk, and up-and-go tests. The findings of this study indicate that a 9-week training program increased upper and lower body strength, aerobic endurance, and agility/dynamic balance in older adults. The most affected components of functional fitness were lower body strength and aerobic endurance. There was no effect of the 9-week training on body composition.     

Reliability of isokinetic and isometric knee-extensor force in older women

Because of the need for efficient, consistent strength measurements, the test-retest reliability of concentric, isometric, and eccentric strength; concentric work; and concentric power was determined in older women without a familiarization session. The reliability of measures derived from a single peak score were compared with those derived from an averaged score. On 2 occasions 25 older women with a mean age of 72 +/- 6 years performed 3 submaximal knee extensions and 5 maximal contractions on an isokinetic dynamometer at 90 degrees/s (CON), 0 degrees/s, and -90 degrees/s on both lower limbs. Statistical analyses for peak and averaged values (best 3 contractions of 5) exhibited good relative reliability (ICCs > .88), except for CON power. Typical error as a coefficient of variation and ratio limits of agreement for peak and averaged score values were larger than desired, with CON power scores demonstrating unacceptable error ranges. Although relative reliability of this 1-session assessment protocol was acceptable, further research is needed to determine whether additional practice trials could enhance absolute reliability.     

The effects of respiratory-muscle training on exercise in older women

This research examined the effects of respiratory-muscle (RM) training on RM function and exercise performance in older women. Twenty-six women (60-69 yr of age) were assessed for spirometry, RM strength (maximal inspiratory and expiratory pressure), inspiratory-muscle endurance, and walking performance to a perceived exertion rating of "hard." They were randomly allocated to a threshold RM training group (RMT) or a nonexercising control group (CON) for 8 wk.After training, the 22% (inspiratory) and 30% (expiratory) improvements in RM strength in the RMT group were significantly higher than in the CON group (p < .05). The RMT group also displayed several significant performance improvements, including improved within-group treadmill performance time (12%) and reductions in submaximal heart rate (5%), percentage of maximum voluntary ventilation (16%), and perceived exertion for breathing (8%). RM training appears to improve RM function in older women. Furthermore, these improvements appear to be related to improved submaximal exercise performance.     

Reflections of older Iranian women: Adapting to life in the United States

Age is an important and often overlooked attribute that influences adjustment to a new cultural context. This paper focuses on the ways in which older Iranian women, who spent their youth and middle adult years in Iran, have adapted to life in the United States. The results are based on extensive interviews with 19 Iranian women over the age of 65 (age range was 65 to 85). Although the majority of women interviewed expressed positive feelings about themselves and a sense of satisfaction with the transitions in their lives, considerable individual differences were identified. These differences focused primarily on the ways in which they attempted to adapt or cope with the new cultural environment in which they were living. Analysis resulted in the identification of three general strategies of adaptation to immigration. These strategies were labeled as withdrawn, insular, and assimilative.     

Comparison of older adult performance during the functional-reach and limits-of-stability tests

Despite widespread use of the functional-reach (FR) and limits-of-stability (LOS) tests, comparisons of postural strategies and postural limits for these tests have not been previously reported. The purpose of this study was to compare postural strategies as determined by cross-correlation analyses of trunk and lower leg angular displacements and postural limits as assessed by maximum center-of-gravity (COG) excursions as older adults at low fall risk completed the FR and LOS tests. Fourteen older adults completed three FR and LOS trials while standing on a Balance Master force platform. Results indicated that despite relatively similar instructions to reach or lean as far as possible without losing balance or altering the base of support, their performance differed with regard to postural strategies employed and maximum COG excursions produced. These findings suggest that because of differences in task constraints, FR and LOS tests should not be used interchangeably.     

The Decline of International Migration as an Economic Force in Rural Areas: A Mexican Case Study

Since 2000, and especially since 2007, there has been a reduction in the importance of international migration and remittances in major global sending regions as a result of recession in receiving countries, anti‐immigrant policies, and improvement in economic opportunities in origin countries. A household survey in five rural communities in Zacatecas, Mexico, in 1995 and again in 2009 exemplifies these trends. Among youthful adults likely to have first migrated in the decade prior to each of these years, there was a significant drop in the proportion of active migrants. Among the active migrants, stays abroad became longer and more permanent, and their households exhibited fewer remittances, less family business ownership, and fewer local purchases, in 2009 compared to 1995. Finally, non‐migrant households greatly improved their economic status in relation to migrant households over the period, reaching approximate parity with their migrant counterparts.     

Poverty and health: older minority women and the rise of the female-headed household

This analysis uses the 1984 Survey on Aging (SOA) supplement to the National Health Interview Survey (NHIS) to compare the relative impacts of poverty and health on the propensity of unmarried older black, Hispanic, and non-Hispanic white women to live with family. The results reveal that for blacks and Hispanics, economics are more significant than health in determining whether a woman lives with her children. Our findings also show that black unmarried elderly females are more likely than similar non-Hispanic white women to head their households. The literature and our findings suggest that black and Hispanic older women have fewer options in living arrangements than non-Hispanic older women in the event of diminished health.     

Awakening to the desires of older women: Deconstructing ageism within fashion magazines

Older women's body image is multidimensional, changes across lifespan, and is a significant source of self-esteem. Ageist social practices in popular fashion magazines and the reluctance of the fashion industry to recognize the sartorial needs of female baby boomer cohorts feed into an internalization of naturally aging women's bodies as socially undesirable. Depression and/or eating disorders are associated with negative internalizations of body image. Despite baby boomers being the most affluent female social group in the United States history and the fashion industry's enormous social influence on women's self-image, few studies have examined the depiction of older women in fashion magazines. Visual content analysis of eight fashion magazines revealed that the fashion industry continues to focus its promotional efforts on youthful populations and seldom includes images of women over forty, regardless of the large percentage of such women among their readership.     

Effect of age and physical activity level on functional fitness in older adults

It is difficult to distinguish between the effects of age and physical activity level in the functional fitness level of older adults. The objective of this study was to determine the effects of age and physical activity level on some functional fitness parameters in community-dwelling older adults.Two hundred twenty-nine elderly (111 female; 118 male) aged between 65–87 years living in the Balçova municipality region were divided into two groups: the young elderly (65–69 years old) and the elderly (70 years old or over). The “seven-day physical activity recall questionnaire” was used to estimate physical activity level (PAL). The functional fitness evaluation included the body mass index (BMI), the lower body strength (LBS), the dynamic balance, and the aerobic endurance. The young elderly were significantly worse with regard to BMI and significantly better with regard to LBS, dynamic balance, and aerobic endurance than the elderly; in contrast, PAL did not affect any of the functional fitness parameters. The young elderly showed worse BMI than the elderly when the age groups were less active. The young elderly showed better LBS and dynamic balance than the elderly when the age groups were more active. The young elderly showed significantly better aerobic endurance than the elderly in both the less and more active age groups. This study confirms that age affects functional fitness, whereas PAL generally does not. However, being more active is advantageous for the young elderly with regard to BMI, LBS, and dynamic balance.     

Religiousness as a predictor of alcohol use in high school students.

The purpose of this study was to examine the relationship between religiousness and alcohol use of adolescents. A sample of high school seniors was drawn based on the second follow-up National Educational Longitudinal Study of 1988 (NELS:88). Multiple regression was employed using a hierarchical strategy to determine the impact of religiousness on alcohol use when accounting for other factors that have been shown to affect alcohol use. The results provide support for examining religiousness variables as predictors of alcohol use patterns for adolescents. Also, inconsistent patterns between Asian-American, Hispanic, African-American, and Caucasian students were detected. Implications of the study and suggestions for future research are offered.     

Patient assertiveness in ethnically diverse older women with breast cancer: Challenging stereotypes of the elderly

Patients' views of patient-physician interactions—particularly the perspectives of older, ethnically diverse women—are poorly understood. The older patient's attitude toward and understanding of the medical encounter, however, are essential to the design of strategies to improve patient-physician communication. To date, investigations have primarily emphasised the ways in which the therapeutic relationship is influenced by immutable patient characteristics. This qualitative study extends previous research findings by looking beyond the effect of ascribed categories (such as age, race, and gender) and focusing on aspects of patient behavior, specifically assertiveness. Focus groups were conducted with older African-, Chinese-, European-, and Hispanic American breast cancer patients from sites in the eastern and western United States. The study explores the potential of a form of patient activation for challenging stereotypes of the elderly and changing health care practitioners' behavior.     

Journey towards independent living: resilience processes of women leaving residential care in South Africa

Among the many youth transitioning to young adulthood, a group that has been found to be particularly vulnerable is young people transitioning out of care, particularly residential care. Research on this population of youth has burgeoned over the past few decades, but in South Africa it remains limited. This article focuses on the resilience processes that facilitate better transitions of young women out of care and towards independent living. It replicates the research design of a previous study with young men, with the aim of determining to what extent the resilience process of young women are similar to those of men. A sample of nine women was purposively selected, interviewed in-depth and data analysed using grounded theory methods. The findings indicate that the same resilience process found among male care-leavers are evident also in the narratives of female care-leavers, confirming the findings of the previous study. However, these processes had a slightly stronger relational focus among women than was seen among men. The authors conclude that similar resilience-building programmes can be implemented to prepare both males and females for leaving care.     

Endogenous hydrogen sulfide insufficiency as a predictor of sexual dysfunction in aging rats

Objective: Our earlier studies showed that endogenous hydrogen sulfide (H₂S) pathway contributed significantly to erectile function. In this study, we tested the hypothesis that age-dependent changes in the bioavailability of H₂S increased the risk of erectile dysfunction (ED). Methods: Young, adult (3-month) and older (18-month) male Sprague-Dawley rats (n?=?6?8/group) were treated daily with sodium hydrosulfide hydrate (NaHS), DL-propargylglycine, sildenafil or l-NAME for 10 weeks. Subsequent to cavernous nerve electrical stimulation, intracavernosal pressure (ICP) responses were determined, and the samples were collected and processed for hormonal (plasma) and gaseous parameters (plasma and erectile corpus cavernosum [CC]) using standard assay protocols. Results: Aging significantly reduced the ICP response (35.9?±?2.0 mmHg vs. 45.2?±?1.9 mmHg in young controls), which was countered by NaHS (53.5?±?6.0) or sildenafil (52.8?±?9.8) treatment. In these rats, marked increments to testosterone (T) or estradiol resulted from NaHS supplementation. Similar to age-dependent decline in NO, the plasma and CC level of H₂S was significantly lower in senescent rats when compared with young animals (p?<?0.05). Conclusion: Our results confirm that ED with aging may be linked to a derangement in the H₂S pathway accompanied by low T levels. It is likely that a pharmacologic intervention delivering H₂S will provide additional benefits to sexual function from an improved T milieu.
