Sensitivity measures of influence on the loading matrix in exploratory factor analysis

For the detection of influential observations on the loading matrix of the factor analysis model, we propose to use the infinitesimal version of two matrix coefficients, including Escoufier (1973)'s also discussed the application in factor analysis of some sensitivity measures used for similar purposes in principal component analysis.

Hazards of stigma: the sexual and physical abuse of gay, lesbian, and bisexual adolescents in the United States and Canada

Some studies suggest lesbian, gay, and bisexual (LGB) teens are at higher risk than peers for violence at home, in school, and in the community. That can bring them into the child welfare system or services for runaway and homeless teens. This study compared self-reported experiences of sexual and physical abuse based on sexual orientation and gender in seven population-based surveys of youth. The authors used c2 and age-adjusted odds of abuse to compare bisexual to heterosexual, mostly heterosexual, and gay and lesbian students. They also provide case studies to illustrate the experiences of such youth.     

Nursing in tele-mental health

This article discusses a cooperative project involving an academic health sciences center, a state university, a women's shelter, and a community mental health center in East Texas, a medically underserved, rural region of Texas. The U.S. Department of Commerce provided grant funding to develop a telehealth network to provide an evaluation, referral, and treatment program for victims of domestic violence. Nurses were involved in all phases of the project, from initial conception through development, implementation, and evaluation. The authors concluded that all of the women involved in the study had significant mental health issues and other health concerns that were not being addressed by the existing health care delivery system. Without the use of telehealth, these women would have had limited access to primary health care and virtually no access to mental health services. The East Texas Tele-Mental Health Network demonstrates the value of the clinical and organizational skills that nurses bring to innovative models of mental health service delivery.     

Health belief dualism in the postnatal practices of rural Swazi women: an ethnographic account

ObjectiveThis study explores and describes the values, beliefs, and practices of rural Swazi women regarding childbearing in the postpartum period.MethodA retrospective ethnographic research design was used. A snowballing sampling method was used to recruit fifteen participants. Face-to-face unstructured audio-taped interviews and field notes were utilised to gather data.FindingsResults showed that rural Swazi women held a dual health belief system of modern and traditional medicinal use; practiced lengthy periods of postpartum confinement; customarily gave regular enemas and traditional medicines to their babies; undertook the specific cultural practice of taking the baby to enyonini [a tree struck by lightening] to perform specific rituals; used self-prescribed pharmacy medicines; used both traditional and modern contraception; as well as practiced breastfeeding.ConclusionRural Swazi women observe modern health practices alongside traditional customary practices that are inherent to their health belief and value systems in the postnatal period. These customary beliefs and values underpin their birth practices postpartum. Recommendations include the need to consider including formal knowledge on cultural aspects of childbirth and postpartum care into midwifery education; a review of maternal care practices and policies to incorporate widely practised traditional elements including redressing the use of self-prescribed pharmacy medicines to ensure a higher level of safety.     

The Effects of Childhood SNAP Use and Neighborhood Conditions on Adult Body Mass Index

The disproportionate number of individuals who are obese or overweight in the low-income U.S. population has raised interest in the influence of neighborhood conditions and public assistance programs on weight and health. Generally, neighborhood effects and program participation effects have been explored in separate studies. We unite these two areas of inquiry, using the 1968-2005 Panel Study of Income Dynamics (PSID) to examine the long-term effects of childhood Supplemental Nutrition Assistance Program (SNAP) participation, neighborhood conditions, and the interaction of these two, on adult body mass index (BMI). Using sibling fixed-effects models to account for selection bias, we find that relative to children in other low-income families, children in SNAP-recipient households have higher average adult BMI values. However, the effects of childhood SNAP usage are sensitive to both residential neighborhood and age at receipt. For those growing up in advantaged neighborhoods, projected adult BMI is higher for children in SNAP-recipient households than for children in low-income, nonrecipient households. In contrast, for those growing up in less-advantaged areas, adult BMI differences between children in SNAP-recipient and those in low-income, nonrecipient households are small. SNAP usage during preschool years (0 to 4) has no impact on adult BMI scores. However, at later childhood ages, the time elapsed receiving SNAP income increases adult BMI values relative to a condition of low-income nonreceipt.     

The Mentoring FAN: A Promising Approach to Enhancing Attunement within the Mentoring System

ABSTRACT

Youth mentoring is a popular tool in positive youth development, with most programs utilizing a model through which youth and non-parental adults are “matched.” Using an adaptation of the Facilitating Attuned Interactions framework, this study sought to explore the effectiveness of the Mentoring FAN in enhancing interpersonal attunement among mentoring staff at two youth mentoring programs in the U.S. Upon completion of the Mentoring FAN training, quantitative (n = 28) and qualitative (n = 15) data were collected from program staff at both sites. Open-ended data from a subset of mentors (n = 27) was also gathered. Results revealed that mentoring staff experienced significant increases in empathy following the Mentoring FAN intervention. Participant interviews revealed increased attunement, increased listening ability, and increased collaboration in the supervisory relationship. Findings support the continued delivery and rigorous testing of Mentoring FAN training, with great promise for enhancing attunement across the mentoring system as a means of strengthening the relationships so critical to this intervention. The study also has important implications for the development of mentor support practices within mentoring organizations, as well as policies designed to meet the needs of youth served by mentoring programs in the U.S.     

Estimation of slowly time-varying trend function in long memory regression models

ABSTRACT

We study the asymptotic properties of the least-squares estimator for the trend function of a particular class of locally stationary models, which are defined by considering a smooth variation of the trend function. Additionally, errors are assumed to be realizations from a long-range dependent stationary Gaussian process. Our findings are then illustrated through Monte Carlo simulations.
