Explicit Versus Implicit Family Decision-Making Strategies Among Mexican American Caregiving Adult Children

Changing U.S. demographics make it increasingly vital to investigate experiences of Latinos caring for aging parents, with specific emphasis on how these families, who often value family closeness, make decisions about caregiving. This study investigates relationships among use of implicit versus explicit decision-making strategies, generation since immigration, and orientation toward family. Findings suggest that those with more recent immigration to the United States were more likely than those who immigrated longer ago to describe family decision making about their parents' care as implicit. Those that were classified as using predominately implicit decision making were also found to be not significantly different from those classified as predominantly explicit with regard to their overall support of a collective orientation toward family. There were exceptions to this, however, regarding two specific aspects of orientation toward family: engagement in shared activities with family members and avoiding family conflict by making choices that are consistent with the family values. In both cases those categorized as implicit expressed stronger endorsement of these specific values. These findings suggest that the relationship between family decision-making strategies, generation since immigration, and orientation toward family is more complex than suggested previously in the literature. Implications for future research and practice are offered.     

Acculturation Gap,Intergenerational Conflict,Parenting Style,and Youth Distress in Immigrant Chinese American Families

This study examined mother–child acculturation gaps in relationship to youth distress and the possible mediating role of parent–child conflict and parenting style in a sample of 81 Chinese American families. Hierarchical multiple regression analyses provided partial support for a relationship between acculturation gaps and youth distress. No mediators of this relationship were found; however, post-hoc analyses indicated that intergenerational conflict and parenting style were associated with youth distress above and beyond acculturation gaps. These results suggest that interventions developed to reduce parent–child conflict and increase parental bonding (increase parental warmth and decrease parental overprotection) may be valuable for Chinese American adolescents, regardless of acculturation gap status.     

Predicting Material Hardship Among Former Welfare-to-Work Participants: An Income- and Resource-Packaging Model

ABSTRACT

Material hardship is of concern because it refers to physical deprivation related to meeting the basic needs of food, housing, utilities, and other items. This study tests a predictive income- and resource-packaging model of material hardship using survey data collected from 459 former welfare-to-work program participants. Logistic regression results show that receiving social support in the form of living rent-free decreased the odds for experiencing material hardship. The predictors of working in the informal economy, being sanctioned while on public assistance, having mental health issues, and having transportation problems all increased the odds for experiencing material hardship. The measures of formal employment income, Temporary Assistance for Needy Families income, work-first program participation, sharing living expenses, monetary social support, and assistance from nonprofit organizations were unrelated to predicting material hardship experiences. Policymakers interested in improving conditions for needy families should question the use of sanctions and carefully monitor material hardship among those sanctioned. Future programs and future research should consider the extent to which low-income women participate in the informal economy to make ends meet, rely on social networks to live rent-free, and struggle with poor health and transportation problems.     

An investigation into the vehicle routing problem with time windows and link capacity constraints

In this work, we investigate a new, yet practical, variant of the vehicle routing problem called the vehicle routing problem with time windows and link capacity constraints (VRPTWLC). The problem considers new constraints imposed on road links with regard to vehicle passing tonnage, which is motivated by a business project with a Hong Kong transportation company that transports hazardous materials (hazmats) across the city and between Hong Kong and mainland China. In order to solve this computationally challenging problem, we develop a tabu search heuristic with an adaptive penalty mechanism (TSAP) to help manage the company's vehicle fleet. A new data set and its generation scheme are also presented to help validate our solutions. Extensive computational experiments are conducted, showing the effectiveness of the proposed solution approach.     

African-American marriage in 1910: Beneath the surface of census data

This paper examines the quality of information about marital status, marital duration, and marriage order among African-American women in the U.S. Census of 1910. It compares the reported prevalence of widowhood to estimates of widowhood based on the mortality of black men and on the ages of women at first marriage. It also compares the reported distributions of duration of first marriage to estimates based on mortality and on age at first marriage. It concludes that census reports are subject to serious error. Widowhood is overreported, and marital turnover appears to have been faster than implied by census reports. The prevalance of "own children" is used to confirm these conclusions and to suggest motivations for misreporting.     

What Makes Koreans Happy?: Exploration on the Structure of Happy Life among Korean Adults

The current study explored the perceptions of Korean people about what can make them happy and constructed a comprehensive measurement of happiness of Korean. A total of 61 Korean adults participated in Focused Group Interview (FGI), where they were asked three questions (e.g., What makes you happy? What could make you happier than now? In general, who is a happy person?). Participants’ responses were reviewed by the present investigators independently and 152 statements of happy life with 18 categories were derived from content-analysis. The list of 152 statements of happy life was administered to 517 Korean adults to assess the importance of each item for Koreans’ happy life through the objective rating scale (6-point Likert scale). Confirmatory factor analysis showed that most factors were unidimensional. The items with low reliability were deleted and some new items were added, resulting in the experimental form of the Happy Life Inventory with 156 items and 18 categories including a new category of religion. The preliminary form of the Happy Life Inventory and the Psychological Well-being scale were administered to a nationwide sample of 1503 Korean adults in order to assess their happiness through 6-point Likert scale. The responses from 877 participants were submitted to exploratory factor analysis. The items with low factor loadings were excluded and 98 items with 16 factors were included in the final version of the Happy Life Inventory. Confirmatory factor analysis of the responses from 611 subjects confirmed that the 16 factor model was appropriate and most categories had one underlying dimension with moderate to high reliabilities. Correlations between the Happy Life Inventory and the psychological well-being scale supported construct validity of the Happy Life Inventory. Suggestions for further research were discussed.     

Bayesian analysis of time series Poisson data

This paper provides a practical simulation-based Bayesian analysis of parameter-driven models for time series Poisson data with the AR(1) latent process. The posterior distribution is simulated by a Gibbs sampling algorithm. Full conditional posterior distributions of unknown variables in the model are given in convenient forms for the Gibbs sampling algorithm. The case with missing observations is also discussed. The methods are applied to real polio data from 1970 to 1983.     

Stochastic approximation Monte Carlo EM for change-point analysis

In the expectation–maximization (EM) algorithm for maximum likelihood estimation from incomplete data, Markov chain Monte Carlo (MCMC) methods have been used in change-point inference for a long time when the expectation step is intractable. However, the conventional MCMC algorithms tend to get trapped in local mode in simulating from the posterior distribution of change points. To overcome this problem, in this paper we propose a stochastic approximation Monte Carlo version of EM (SAMCEM), which is a combination of adaptive Markov chain Monte Carlo and EM utilizing a maximum likelihood method. SAMCEM is compared with the stochastic approximation version of EM and reversible jump Markov chain Monte Carlo version of EM on simulated and real datasets. The numerical results indicate that SAMCEM can outperform among the three methods by producing much more accurate parameter estimates and the ability to achieve change-point positions and estimates simultaneously.
