Reducing attrition in physical activity programs for older adults

This study investigated attrition in a 6-month physical activity intervention for older adults. The program was based on the social-cognitive theory incorporating self-efficacy factors. Two hundred forty-eight insufficiently active 65- to 74-year-olds were recruited from the Australian federal electoral roll. The intervention comprised walking and strength and flexibility exercises and was conducted in 30 local neighborhoods where the participants resided. Characteristics of individuals lost to attrition (n = 86, 35%) were compared with those of program completers (n = 162, 65%). Logistic-regression analysis showed that those lost to attrition came from areas of lower socioeconomic status, were overweight and less physically active, and had lower walking self-efficacy scores and higher loneliness scores. The results suggest that early assessment of these characteristics should be undertaken to identify individuals at risk of attrition, to improve retention, and to avoid potential bias.     

Human Capital,Social Support,and Economic Well-being among Rural,Low-income Mothers: A Latent Growth Curve Analysis

The purpose of this study was to better understand human capital and social support in the long-term economic well-being of rural, low-income mothers in the US. Three waves of data from a multi-state, longitudinal investigation tracking the well-being of rural families, known as “Rural Families Speak,” were used to test two latent growth curve models of economic well-being. Results indicated that human capital alone is not a good predictor of economic well-being over time for this sample. A model of economic well-being that includes both social support and human capital provides a better fit for these data. Findings suggest that social support is a key contributor to long-term economic success for this sample. Implications for public policy are presented.

Management of premature menopause

There has been some confusion among women and health professionals since the publication of the Women's Health Initiative and Million Women studies about the management of premature ovarian failure (POF). Both studies were undertaken in women aged 50 and over, and cannot be extrapolated to their younger counterparts, who would normally be producing their endogenous estrogen, since they have functioning ovaries. Estrogen-based replacement therapy is the main stay of treatment for women with POF and is recommended at least until the average age of natural menopause (52 years in the UK). This view is endorsed by regulatory bodies such as the Committee on Safety of Medicines (now the Commission on Human Medicines) in the UK. No evidence shows that estrogen replacement increases the risk of breast cancer to a level greater than that found in normally menstruating women, and women with POF do not need to start mammographic screening early unless other risk factors are present, such as family history.     

Intercountry Adoption Flows from Africa to the U.S.: A Fifth Wave of Intercountry Adoptions?

This article addresses whether there is the beginning of a fifth wave of intercountry adoptions (ICAs) from Africa to the United States (U.S.). ICAs function as a “quiet migration” of children [ Weil (1984) International Migration Review 18(2):276–293; Lovelock (2000) International Migration Review 34 (3):907–949; Selman (2002) Population Research and Policy Review 21:205–225]. U.S. Department of Justice Immigration and Naturalization Service (INS) data from 1971 to 2009 indicate that there were 421,085 ICAs to the U.S. Tarmann (2003:2 , http://www.prb.org/Articles/2003/InternationalAdoptionRateinUSDoubledinthe1990s.aspx?p=1 ) reported that in 2000, U.S. parents completed one ICA for every 200 births. In the past, top sending countries have followed flows from Europe, South America, and Asia. INS data are used to analyze the increase in the intercountry adoptees from Africa from 1996 to 2009. Similar Hague Convention data are used for the comparison of the number of ICAs from Africa to other top recipient nations. Demographic and economic data are used to support the suggestion that ICAs, similar to other migratory flows, are from developing to developed countries.     

Slicing Up the Pie: Allocation of Central Government Funding of Care of Older People

The allocation of central government funds is a critical element in the equitable provision of local authority‐commissioned and ‐provided services. A variety of approaches to allocating funding for social services for older people have been used over the years, most recently founded on ‘needs‐based’ formulae. In 2004, the Department of Health for England commissioned research to help inform the improvement and updating of the formula. The results of individual‐level analyses were compared with the results obtained from analyses of small area (ward‐level) data on service users. Both analyses were affected by problems of data availability, particularly the individual‐level analysis, and the Department of Health and the (then) Office of the Deputy Prime Minister decided that the formula calculations should be based on the results of the small area analysis. However, despite the differences in approach, both methods produced very similar results. The correlation between the predicted relative needs weights for local authorities from the two models was 0.982. The article discusses the strengths and weaknesses of each approach and developments that could allow a normative approach that would incorporate future policy objectives into formulae that, to date, have inevitably been based on historical data and service patterns.     

Flow shop scheduling by transportation model

This paper describes the classical problem of scheduling n jobs on m machines in a flow shop. A schedule evaluation algorithm is presented, which for job-pairs, generates a schedule evaluation matrix. The matrix is the input data to a transportation problem, the solution of which gives near-optimal jobsequence and makespan. The performance of the algorithm is discussed.     

Lessons Learned From the First-Year Evaluation of a Small-Scale Home Visitation Program

ABSTRACT

Home visitation programs to prevent child maltreatment are offered in many communities. Agencies in these communities want to help families in need while under increased pressure to provide effective services. Funding is limited and competitive; some agencies might choose to limit funds spent on supervision, training, and evaluation as a way to provide more direct service. In this article, we use an implementation science framework and the results of an evaluation of a small home visitation program to underscore the importance of ongoing training and supervision, attention to fidelity, and program evaluation. The evaluation included 17 families entering the program during 21 months. Evaluators visited families in their homes at the beginning of the program and again 10 months later. Like many other well-intended, small-scale programs, this one “borrowed” from evidence-based models and expanded enrollment criteria in an attempt to better serve families. Findings from the evaluation suggest that the program, as it was carried out, was not effective at reducing parenting behaviors known to be associated with child maltreatment. We offer advice to funding and community agencies based on these findings and implementation science. Future evaluation research must pay greater attention to fidelity and implementation.     

Youth supervision while mothers work: a daily diary study of maternal worry

Using data from a daily diary study of hourly hotel employees in the US and their children, this study examined links between youth supervision arrangements and maternal worry while at work, examining both differences between individuals and day-to-day variation within individuals. Multilevel model analyses revealed both between- and within-person effects linking youth supervision to maternal worry. Mothers’ partner status functioned as moderator, and maternal knowledge also emerged as a protective factor when youth were in self-care, highlighting a potential target for future work–family interventions, particularly those for hourly employees with limited access to family-friendly workplace policies.
