Outcomes of a revised apprentice carpenter fall prevention training curriculum

Falls from heights are a leading cause of morbidity and mortality among construction workers, especially inexperienced workers and those performing residential construction. This research reports changes in fall prevention behaviors following revision of fall prevention training in a union-based carpenters' apprenticeship program. We used a comprehensive needs assessment to identify gaps in apprentice carpenters' preparation to work at heights, used these results to guide a school-based fall prevention curriculum to fill these gaps, and measured the effects of the revised curriculum on knowledge, beliefs, and fall prevention behaviors.     

Prediction of body fat in older adults by time spent in sedentary behavior

The purpose of the study was to determine the relationship between sedentary behavior (SB), physical activity (PA), and body fat (total, abdominal) or body size (body-mass index [BMI], waist circumference [WC]) in community-dwelling adults 50 yr old and over. This study included 232 ambulatory adults (50-87 yr, 37.4% ± 9.6% body fat [BF]). Average daily time spent in SB (<100 counts/min) and light (100-759 counts/min), lifestyle-moderate (760-1,951 counts/min), walking-moderate (1,952-5,724 cts/min), and vigorous-intensity (≥ 5,725 counts/min) PA were determined by accelerometer and corrected for wear time. BF was measured with dual-energy X-ray absorptiometry. SB was positively related to measures of BF. Measures of SB, PA, and gender accounted for 55.6% of the variance in total BF, 32.4% of the variance in abdominal fat, and 28.0% of the variance in WC. SB, PA, and age accounted for 27.1% of the variance in BMI. Time spent in SB should be considered when designing obesity interventions for adults 50 yr old and over.     

‘Nobody wants to sound like a provinciano’: The recession of unstressed vowel devoicing in the Spanish of Cusco,Perú1

This study documents changes in the prevalence and evaluation of unstressed vowel devoicing, a salient characteristic of Andean Spanish, in the city of Cusco, Perú following an earthquake in 1950. This event brought city residents into contact with other dialects of Spanish that lack vowel devoicing and also intensified their exposure to the Quechua‐accented Spanish of rural migrants, or provincianos, which is characterized by this pronunciation. Results of an attitude‐perception study indicate that younger Cusqueñans are aware of devoicing and identify it primarily with the speech of provincianos rather than the Spanish of their city. However, acoustic analysis of interviews conducted with Cusqueñans and provincianos shows that, while the pronunciation is receding from Cusco Spanish, many city natives actually exhibit rates of devoicing similar to those of rural migrants. Cusqueñans’ nearly exclusive association of devoicing with provincianos is attributed to local ideology, including negative attitudes toward rural Andean identity. La presente investigación describe cambios en Ia incidencia y evaluación del ensordecimiento de las vocales átonas, una peculiaridad notable del español andino en Cusco, Perú, durante las décadas posteriores al terremoto que devastó Ia ciudad en 1950. Debido a este acontecimiento, los cusqueños aumentaron su contacto con otros dialectos del español que no exhiben el ensordecimiento vocálico así como con el español de los inmigrantes de zonas rurales, o provincianos, que se caracteriza por este fenómeno fonético. Los resultados de un estudio de actitudes indican que los cusqueños jóvenes son conscientes del ensordecimiento vocálico y lo identifican con el acento de los provincianos pero no lo relacionan con el habla de su propia ciudad. Sin embargo, según el análisis acústico de las entrevistas realizadas a cusqueños y a provincianos, muchos residentes de Ia ciudad siguen empleando esta pronunciación con básicamente Ia misma frecuencia que los provincianos. La asociación del ensordecimiento vocálico con los provincianos, casi exclusiva por parte de los cusqueños jóvenes, es atribuida a actitudes negativas hacia Ia identidad rural andina. [Spanish]     

Variance estimation for two‐phase stratified sampling

The authors consider variance estimation for the generalized regression estimator in a two‐phase context when the first‐phase sample has been restratified using information gathered from the first‐phase sample. Simple computational expressions for variance estimation are provided for the double expansion estimator and the reweighted expansion estimator of Kott & Stukel (1997). These estimators are compared using data from the Canadian Retail Commodity Survey.     

Parental transfers, student achievement, and the labor supply of college students

Using nationally representative data from the NLSY97 and a simultaneous equations model, this paper analyzes the financial motivations for and the effects of employment on U.S. college students’ academic performance. The data confirm the predictions of the theoretical model that lower parental transfers and greater costs of attending college increase the number of hours students work while in school, although students are not very responsive to these financial motivations. They also provide some evidence that greater hours of work lead to lower grade point averages (GPAs).     

Assessing Causality and Persistence in Associations Between Family Dinners and Adolescent Well‐Being

Adolescents who share meals with their parents score better on a range of well‐being indicators. Using 3 waves of the National Longitudinal Survey of Adolescent Health (N = 17,977), the authors assessed the causal nature of these associations and the extent to which they persist into adulthood. They examined links between family dinners and adolescent mental health, substance use, and delinquency at Wave 1, accounting for detailed measures of the family environment to test whether family meals simply proxy for other family processes. As a more stringent test of causality, they estimated fixed‐effects models from Waves 1 and 2, and they used Wave 3 to explore persistence in the influence of family dinners. Associations between family dinners and adolescent well‐being remained significant, net of controls, and some held up to stricter tests of causality. Beyond indirect benefits via earlier well‐being, however, family dinners associations did not persist into adulthood.     

Love and hooking up in the new millennium: communication technology and relationships among urban African American and Puerto Rican young adults

Communication technology is a central feature of young people's lives, but its role in romantic and sexual relationships has not been thoroughly examined. This article describes how young adults use communication technology for partnering across relationship stages (formation, maintenance, and dissolution) and types (serious/casual), and proposes implications of usage in relationships. This study analyzed qualitative data from a five-week, prospective, coital diary method with related debriefing interviews (N = 70) of African American and Puerto Rican men and women aged 18 to 25 years in Hartford and Philadelphia. Cell phones, including calls, text messaging, and mobile Internet, were the most common forms of communication technology used for partnering goals. Participants reported using cell phones to pursue partnering goals across all relationship stages, including formation (meeting, screening, and getting to know new partners), maintaining existing relationships, and breaking up. Cell phone uses depended on the type of relationship (serious/casual) and the participants' intentions and desires. Results indicated that cell phones are an important element of communication among young adults in romantic and sexual relationships. Specific features of cell phone communication shape the process and context of partnering. Future research should explore emerging communication technologies and implications for psychosocial development, dating violence, and sexual behavior.     

Passing by the Girls? Remittance Allocation for Educational Expenditures and Social Inequality in Nepal’s Households 2003–2004

We examine the utilization of remittances for expenditures associated with development, specifically children's education. We use household-level data from the Nepal Living Standards Survey (NLSS II, 2003–04) to separate remittance effects from general household income effects to demonstrate the migration–development relationship reflected in child schooling investment. We find that family-household remittances are spent on education of children, but the expenditures are disproportionately for boys' schooling. Only when girls are members of higher-income households do greater schooling expenditures go to them. This gender-discriminating pattern at the household level contrasts with the call for universal and gender-equal education.     

Family Reunification of Youth in Foster Care with Complex Mental Health Needs: Barriers and Recommendations

This study presents findings of a formative evaluation of an innovative pilot program designed to reunify and reintegrate foster youth with complex mental and behavioral needs in residential treatment centers or therapeutic foster care with their families in the community. Data collection methods included in-depth structured case file reviews and semi-structured interviews with the youth, as well as their caregivers, Child Protective Services caseworkers, and pilot program staff. The participants provided important insights regarding system, program, and case-level barriers to the successful reunification of these youth back into the community. Training, practice, and policy recommendations are discussed.
