Leg-extension strength and chair-rise performance in elderly women with Parkinson's disease

The lower extremity performance in elderly female patients with mild to moderate Parkinson's disease (PD; n = 12) and controls (n = 16) was compared. Isometric dynamometry and force-plate measurements were used. PD patients had lower (p < .05) bilateral (BL) maximal isometric leg-extension force (MF), BL isometric MF relative to body mass, and maximal rate of isometric force development than control participants. BL strength deficit was greater (p < .05) in PD patients than in controls. A significantly longer chair-rise time and lower maximal rate of vertical-ground-reaction-force development while rising from a chair was found in PD patients than in controls. These findings suggest that elderly women with PD have lowered voluntary isometric force-generation capacity of the leg-extensor muscles. Reduced BL leg-extension strength might contribute to the difficulty of individuals with PD to rise from a chair.     

Substance abuse, suicidality, and self-esteem in South African adolescents

Associations among six different domains of self-esteem (peers, school, family, sports/athletics, body image, and global self-worth) and risk behaviors related to substance use and suicidality were investigated in a sample of South African adolescents. Students enrolled in Grades 8 and 11 at independent secondary schools in Cape Town (N = 116) completed the Self-Esteem Questionnaire (SEQ) and a questionnaire that asked about their participation in a range of risk behaviors. Logistic regression analyses indicated that particular domains of self-esteem were differentially associated with indicators of alcohol, cigarette and drug use and suicidal ideation or behaviors in adolescents. Family self-esteem showed the strongest overall pattern of associations with the risk behaviors. Overall, the findings of this study suggest that interventions which aim to protect adolescents from engaging in risk behaviors by increasing their self-esteem are likely to be most effective and cost-efficient if they are aimed at the family and school domains.     

In sickness but not in health: self-ratings, identity, and mortality

Self-rated health as a predictor of mortality has been studied primarily in large, representative populations, with relatively little progress toward understanding the information processing that individuals use to arrive at these ratings. With subsamples of National Health and Nutrition Examination Survey (NHANES) Epidemiologic Follow-up Study (NHEFS) data for respondents with circulatory system disease (N = 3,709) and respondents with no diagnosable disorders (N = 1,127) at baseline, we test the idea that individuals with experience of chronic disease of the circulatory system will have more predictive self-ratings of health than healthy individuals. Poor or fair self-rated health increased the adjusted hazard of all-cause mortality for respondents with circulatory system disease, but not for respondents who were healthy. Additional analyses confirm that poor or fair self-rated health is particularly predictive for respondents with self-reported history of circulatory system diagnoses and perception of symptoms, but not for respondents without symptoms or diagnoses prior to the NHANES physical exam.     

Sociology and political arithmetic: some principles of a new policy science

This paper advances the position that sociology needs to develop an approach to research which focuses on fundamental social problems. In doing so it shares many of the intellectual values and goals of political arithmetic while seeking to move methodologically beyond it. Since such problems are complex they will require, typically, interdisciplinary input and a concomitant approach to the development and appraisal of theories. We are not, therefore, advocating the primacy of sociology but arguing that it has a distinctive part to play in addressing the fundamental problems of the twenty-first century. However, a policy-oriented sociology has also to take up the task, so clearly defined by the tradition of political arithmetic, which is to hold governments to account. Consequently a central principle of a new policy science is that it should contribute to democratic debate about policy.     

The effectiveness of job specific training on the occupational performance of student nurses

Body mechanic checklist scores during a one-person pivot transfer, and boosting up in bed were evaluated to determine the effectiveness of training on the work performance of female student nurses from a local college. Thirty subjects participated in the study and were divided into a control group, an experimental group that received basic body mechanic training, and an experimental group that received job specific training. A one-way ANCOVA was calculated to examine the effects of the experimental procedures on the subjects' performance. This revealed a statistically significant difference between the groups (patient transfer F = 10.11, p value < 0.001; boosting F = 38.62, p value < 0.001). A post hoc analysis (Bonferroni procedure) indicated that the job specific training group (mean 11.65, SD 0.66) demonstrated a statistically significant improvement in their performance compared to the other two groups (control group mean 7.5, SD 0.67; BBMT mean 9.66, SD 0.67).     

The potential of the SSI program to reduce poverty among the elderly

Is it more effective to reduce poverty among the elderly by increasing the benefits paid by the Supplemental Security Income (SSI) program or by increasing eligibility for the program? This paper answers that question from a policymaker's perspective. At given program cost levels, we compare the potential reduction in poverty from increasing benefit levels to the potential reduction associated with a variety of policy proposals that would increase eligibility for the program. This paper employs a microsimulation model containing an eligibility and benefits calculator, a participation model, and an optimization algorithm. The data are from the Survey of Income and Program Participation supplemented by the administrative records of the SSI program. The results show that increasing eligibility by relaxing the restrictions of the means tests can be more effective in reducing poverty than raising benefit levels.     

Temporary and illegal labour migration: the Israeli experience

In recent years, Israel has become a major recipient of documented and undocumented temporary labour migrants from many countries outside the Middle East region. The purposes of this article are to describe Israel's experience of temporary labour migration and its concomitant, illegal labour migration; and also to explore what her policies on temporary labour migration indicate about the nature of the policy-making process in this policy domain in Israel.
To these ends the article traces the evolution of temporary labour migration – legal and illegal – and recent policy initiatives of the Israeli government. It then considers some of the major conceptions of the policy-making process found in public policy literature. The article concludes by pointing to the uniqueness of Israel's experience of temporary labour migration and to the fact that her policies have been overwhelmingly reactive – inadequately considered, ill-conceived, ambivalent in relation to their ultimate purpose and, in the course of implementation, vulnerable to "privatization" (being taken over by vested interest groups).
Analysis of the most recent policy initiatives designed to reduce the number of legal labour migrants and address the problem of illegal labour migrants, reflect a policy-making process that is not followed by commensurate action.     

Family migration and the economic status of women in Malaysia

"The impact of family migration on women's economic position in a developing country setting is an area that has received relatively little research attention. Incorporating a lifetime perspective, this study makes use of the retrospective migration histories of husbands and wives from the second round of the Malaysian Family Life Survey to estimate how joint migration with the husband affects women's socioeconomic achievement. The findings show that family migration depresses the chances of working, but it does not significantly reduce socioeconomic attainment of those who do work. However, when a woman migrates with her husband she does forgo the substantial advantage she could have derived had she moved alone."     

Implementing a gender policy in ACORD: strategies,constraints, and challenges

ACORD, a consortium of 11 nongovernmental organizations from Europe, Asia, and North America devoted to poverty alleviation in Africa, formally adopted a gender policy in 1990 aimed at reducing gender-based inequities in communities where ACORD works. A 1994-96 survey of field programs indicated that the greatest gains for women had been recorded in the areas of welfare, access to resources, conscientization (awareness of and will to alter gender inequalities), and, to a lesser extent, participation; minimal progress was noted in shifting the prevailing gender-based imbalance of power and control in public or private spheres. The research identified several programming and organizational strategies that have promoted positive outcomes for women: gender-awareness training for staff and community members, working with mixed groups, working with women-only groups, promotion of female leadership, gender-aware participatory planning and evaluation, spreading responsibility throughout the organization for implementing the gender policy, recruitment and promotion of women staff, networks for women staff, and direct field involvement in research. Also identified were internal and external factors that weakened policy implementation: a lack of clarity as to its aims, culture-based resistance, confusion regarding responsibilities and procedures, weak accountability mechanisms, lack of gender impact indicators, training inadequacies, underrepresentation of women staff, and inadequate resources. As a result of the review process, ACORD has given gender issues centrality in its current 5-year strategic plan.
