A Note on a Bayesian Approach to a Dichotomous Choice Environmental Valuation Model

As an alternative to the classical approach for analysing dichotomous choice environmental valuation data, this note develops a Bayesian approach by using the idea of Gibbs sampling and data augmentation. A by-product from the approach is a welfare measure, such as the mean willingness to pay, and its confidence interval, which can be used for policy analysis.     

Social networks among lower income Korean elderly immigrants in the U.S.

This study examines the composition and cultural context of the social networks of a sample of primarily lower-income Korean elderly immigrants and the resources and supports available through those network ties. In-depth, in-person interviews were used to investigate categories of network ties and the nature of network exchanges. Non-kin and organizational contacts were primary sources of emotional and instrumental support among this sample, with the norms and institutions of elder care in the U.S. shaping expectations regarding sources of support.     

How U.S. state tourism offices use online newsrooms and social media in media relations

This study examined the use of online newsrooms on U.S. state tourism websites. A content analysis of 50 state tourism websites was conducted to investigate the availability of online newsrooms as well as their contents and overall usability. The social media availability on the state tourism websites was also analyzed. The results revealed that most state tourism websites provide online newsrooms to media but many of them do not meet the needs of journalists in terms of usability, content availability, and information distribution. All of the websites integrated at least one type of social media; the most commonly used were Facebook, Twitter, YouTube, and Flickr. The detailed results by state and implications are discussed.     

A Virtual Field Practicum: Building Core Competencies Prior to Agency Placement

ABSTRACT

Providing effective services to clients with increasingly severe challenges in an era of fiscal constraints calls for schools of social work to assume greater responsibility for preparing interns for clinical practice. This article describes a virtual field practicum (VFP), an online skill-building experience designed to meet this need and reports preliminary findings. The VFP employs client simulation and other experiential activities; its intent is to foster student acquisition of core competencies prior to agency placement. Longitudinal data were collected on VFP students and their traditional counterparts across 4 semesters. Results show that VFP students performed as well, if not slightly better, on competency measures than traditional students, suggesting that this model is a viable option for educators to consider.     

Recurrence of child maltreatment substantiation: findings from the administrative data of South Korea’s National Child Protection Agency

The recurrence of child maltreatment substantiation among families served by South Korea’s Child Protection Agency has yet to be thoroughly investigated. This study explores the recurrence of child maltreatment substantiation and related risk factors using the administrative data from the National Child Protection Agency (NCPA) . Multilevel discrete time-hazard analysis is employed. We found that the risk of recurrence is greatest during the first month after initial substantiation. Younger children, those with disabilities, children with a greater number of vulnerabilities, families on welfare, father-headed families and impoverished communities had a heightened risk of recurrence of child maltreatment substantiation. The implications of the findings are discussed.     

Constructing deservingness: federal welfare reform,supplemental security income,and elderly immigrants

On August 22, 1996, President Clinton signed the welfare reform law that ended eligibility for all immigrants to federal means tested entitlements. Poor elderly immigrants on Supplemental Security Income were specifically targeted. This article documents how the print media responded to these policy changes. The following are the major research questions: (1) How were older immigrants on Supplemental Security Income portrayed in the print media before and after federal welfare reform? (2) Who was involved in the print media coverage of older immigrants on Supplemental Security Income before and after federal welfare reform? (3) What types of statements were made by those involved in the print media coverage of older immigrants on Supplemental Security Income, before and after federal welfare reform? The approach used was an in-depth content analysis of newspaper articles from major U.S. newspapers. The findings demonstrate that older immigrants were constructed as "undeserving" in news articles prior to the passage of the federal welfare reform bill. However, after the passage of the federal welfare reform bill the coverage of older immigrants on Supplemental Security Income started to change, and older immigrants were portrayed as "deserving." In advancing aging policy for poor, vulnerable elderly, such as elderly immigrants, advocates, health and social service providers can play an influential role in bringing their voices to the print media.     

Sufficient dimension reduction through informative predictor subspace

The purpose of this paper is to define the central informative predictor subspace to contain the central subspace and to develop methods for estimating the former subspace. Potential advantages of the proposed methods are no requirements of linearity, constant variance and coverage conditions in methodological developments. Therefore, the central informative predictor subspace gives us the benefit of restoring the central subspace exhaustively despite failing the conditions. Numerical studies confirm the theories, and real data analyses are presented.     

The Associations Between Socioeconomic Status,Caregivers' Depressive Symptoms,Children's Health‐Promoting Behavior,and Children's Physical Health: A Mediation Model

The aim of this study was to examine the mediating effects of children's health‐promoting behaviors on the association between socioeconomic status, caregivers' depressive symptoms, and children's physical health outcomes. We used the first wave of “Seoul Education and Health Welfare Panel.” Data were collected from 820 fourth‐grade elementary and first‐year middle school students and their caregivers using self‐administered surveys. Structural equation modeling was employed to analyze the mediating effects of health‐promoting behaviors. Bias‐corrected bootstrap confidence intervals were used to test the mediating effect. The results showed that both low socioeconomic status and caregivers' depressive symptoms were negatively associated with a child's health‐promoting behaviors. Children's health‐promoting behaviors were positively associated with physical health. However, children's physical health was not significantly associated with socioeconomic status but was marginally associated with caregivers' depressive symptoms. We found that children's health‐promoting behaviors significantly mediated associations between both socioeconomic status and children's physical health and between caregivers' depressive symptoms and children's physical health. Based on the findings, we suggest the development and implementation of school‐based, health‐enhancement programs as a means to improve the general health of all children and to reduce health inequalities.
