Formal volunteering as a protector of health in the context of social losses

This study aims to examine the effect of the death of a family member or friend on psychological well-being, specifically the moderating effects of first-time volunteering and social network. With the sample of 354 volunteers from the Experience Corps® (EC) programs, Analysis of covariance (ANCOVA) estimated the differences in psychological well-being. Among volunteers who had experienced the death of a family member or friend, new volunteers showed significant improvement in positive affect compared to experienced volunteers. EC members gained additional social contacts through volunteering. Formal volunteering has a salutatory effect on older adults' health after the loss of family members.     

Race and Place: Exploring the Intersection of Inequity and Volunteerism Among Older Black and White Adults

Although the historical impact of racial segregation and ongoing health and economic inequities between older Black and White adults is well documented, little is known about the relationships among race, individual- and neighborhood-resources, and formal volunteering in later life. This study explores this intersection. Individual-level data from 268 respondents aged 55+ were collected in the St. Louis metropolitan area through paper-based mail surveys. Objective neighborhood data were obtained at the zip code level from secondary sources and matched with respondents. Using exploratory factor analysis, we constructed a 14-item environmental scale with 3 neighborhood dimensions (economic, social, and built environment). Older Black adults had lower levels of education; had fewer financial assets; lived in neighborhoods with less economic resources and lower built environment scores; and fewer formally volunteered when compared to older White adults. Individual resources (financial assets, health) and neighborhood resources (social and built environment) were positively associated with formal volunteering among older Black adults. Only individual resources (age, marital status, financial assets, health) were associated with formal volunteering among older White adults. A coherent set of policies that bolsters individual and environmental capacities may increase the rate of volunteerism among older black adults.     

Copper mining productivity: Lessons from Chile

Chile represents almost one third of the world’s copper production. Mining is one of the main industries that contributes to our country’s development with resources and is globally recognized. Due to the end of the commodity cycle, improving productivity will be a key variable in mining performance in incoming years. This paper studies mining productivity in Chile by relying on two indicators: measure of the total factor productivity (TFP) using the traditional Solow methodology, and labor productivity. Since 2000, we found a decrease in TFP, explained mainly by the participation of capital as well as diverse factor adjustments to labor and capital inputs. Average labor productivity also decreases 42% from 1999 to 2010, a decrease explained by four determinants: real mining wages, electricity prices, copper prices and mineral grade. Since 2010, average labor productivity has increased 30%, and there is also an opportunity for additional improvement by reducing energy costs as well as by aligning productivity and labor performances.     

Mexican American Adolescents' Emotional Support to the Family in Response to Parental Stress

In this two‐wave longitudinal, daily diary study that followed up with 421 Mexican American parent–adolescent dyads (adolescents: M_age = 15 years, 50% males) after 1 year, we investigated the contingency between parental stressors and adolescents' emotional support to family members. Adolescents provided support to their parents and other family members at similar rates, but adolescents were more likely to provide support to other family members than to their parents on days when parents experienced a family stressor. This pattern was especially pronounced in families with parents who reported physical symptoms and adolescents with a strong sense of family obligation. Adolescents' provision of emotional support was associated with same‐day feelings of role fulfillment, but not to their concurrent or long‐term psychological distress.     

Neighborhood Qualification of the Association Between Parenting and Problem Behavior Trajectories Among Mexican‐Origin Father–Adolescent Dyads

To address the combined importance of fathers and neighborhoods for adolescent adjustment, we examined whether associations between fathers' parenting and adolescents' problem behaviors were qualified by neighborhood adversity. We captured both mainstream (e.g., authoritative) and alternative (e.g., no‐nonsense, reduced involvement) parenting styles and examined parenting and neighborhood effects on changes over time in problem behaviors among a sample of Mexican‐origin father–adolescent dyads (N = 462). Compared to their counterparts in low‐adversity neighborhoods, adolescents in high‐adversity neighborhoods experienced greater initial benefits from authoritative fathering, greater long‐term benefits from no‐nonsense fathering, and fewer costs associated with reduced involvement fathering. The combined influences of alternative paternal parenting styles and neighborhood adversity may set ethnic and racial minority adolescents on different developmental pathways to competence.     

Risk,Protection, and Resilience Among Youth Residing in Public Housing Neighborhoods

Constructs of risk, protection, and resilience were examined from the perspectives of 20 ethnically diverse elementary and middle school children residing in urban public housing neighborhoods. Participants attended an afterschool program at locations in each of the neighborhoods. Analyses generated five themes: (1) challenges (community-neighborhood, peer, school, family, and personal); (2) coping (behavioral, emotional, spiritual, and cognitive); (3) health (community-neighborhood, peer, school, family, and personal); (4) connection (relationships that provide companionship, esteem, information, and instrumental support); and (5) aspirations. Implications of the findings for preventing problem behavior and promoting healthy development among young people in public housing settings are identified.     

The Familial Socialization of Culturally Related Values in Mexican American Families

Research has documented a relation between parents' ethnic socialization and youth's ethnic identity, yet there has been little research examining the transmission of cultural values from parents to their children through ethnic socialization and ethnic identity. This study examines a prospective model in which mothers' and fathers' Mexican American values and ethnic socialization efforts are linked to their children's ethnic identity and Mexican American values, in a sample of 750 families (including 467 two-parent families) from an ongoing longitudinal study of Mexican American families (Roosa, Liu, Torres, Gonzales, Knight, & Saenz, 2008). Findings indicated that the socialization of Mexican American values was primarily a function of mothers' Mexican American values and ethnic socialization, and that mothers' Mexican American values were longitudinally related to children's Mexican American values. Finally, these associations were consistent across gender and nativity groups.     

Modeling categorical covariates for lifetime data in the presence of cure fraction by Bayesian partition structures

In this paper, we propose a Bayesian partition modeling for lifetime data in the presence of a cure fraction by considering a local structure generated by a tessellation which depends on covariates. In this modeling we include information of nominal qualitative variables with more than two categories or ordinal qualitative variables. The proposed modeling is based on a promotion time cure model structure but assuming that the number of competing causes follows a geometric distribution. It is an alternative modeling strategy to the conventional survival regression modeling generally used for modeling lifetime data in the presence of a cure fraction, which models the cure fraction through a (generalized) linear model of the covariates. An advantage of our approach is its ability to capture the effects of covariates in a local structure. The flexibility of having a local structure is crucial to capture local effects and features of the data. The modeling is illustrated on two real melanoma data sets.     

Caring for Individuals with Chronic Illness and Minor Depression: Latino Perceptions of Caregiver Burden

ABSTRACT

Informal caregiving can be fundamental to disease management. Yet, the psychosocial, physical, and financial burden experienced by caregivers can be significant. In the US, Latinos experience increasing rates of chronic conditions, the highest uninsured rates in the country, and a growing dependence on informal caregivers. This article explores the impact of caregiving on caregivers of individuals with comorbid chronic disease and depression. Findings highlight the impact of caregiving on financial insecurity, balancing competing demands, increased emotional distress, and community supports. Findings support the inclusion of caregivers in disease management programs to enhance psychosocial outcomes for both caregivers and their patients.
