The Influence of Social Networks and Supports on Health: Differential Pathways for Older Korean Immigrants and Non-Hispanic Caucasians

Jeon, Haesang January 2013 (has links)
Thesis advisor: James Lubben / It has been shown that the effect of social networks and social support systems on health may be greater among immigrants who live away from their homeland and their natural social support systems. Despite the significance of social support systems, relevant research on minorities in the U.S. is limited. For this reason, the current cross-cultural study examined the pathways underlying different formations of social networks (kin vs. non-kin) and social support systems (emotional vs. instrumental), which affect depression symptoms and perceived general health among older Korean immigrants and non-Hispanic Caucasians in the United States. This analysis is based on the secondary data from the "Korean-American Elderly: Social Supports and Long-Term Care" study conducted in 1994. The data (n=424) were collected from non-Hispanic White Americans (n=201) and Korean immigrant elders (n=223) aged 65 and older residing in Southern California. Structural equation modeling (SEM) was used to test the proposed conceptual model designed to explain the direct and indirect relationships between social networks and social support on health outcomes. Empirical evidence from this study indicated different effect of one's social networks and social support on health by race/ethnicity. The result indicated that both kin and non-kin networks provided social support for Korean immigrants. Moreover, among social network measures, non-kin networks had a greater effect on social support for older Korean immigrants compared to kin networks. For non-Hispanic Caucasians, on the other hand, only kin network had a significant effect on social support systems. In addition, receiving instrumental support lowered the perceived general health among older non-Hispanic Caucasians. The work discussed in this paper pointed to the need to recognize the role of culture in assessing the effect of one's social networks and social support systems on health. This paper highlighted the characteristics of those older Korean-American and older non-Hispanic Caucasians who are most, as well as, least likely to benefit from social networks and social support systems. By utilizing the existing social networks and social support of diverse populations, we can improve overall health outcomes and serve the elderly community better. / Thesis (PhD) — Boston College, 2013. / Submitted to: Boston College.

Cross-cultural analysis Of elementary school children's values and perceptions of support systems: A secondary analysis of the Promoting Psychological Well-Being Globally project

January 2018 (has links)
archives@tulane.edu / Multicultural psychologists have discussed the growing concern over ecological validity in understanding children’s mental health: insufficient participatory efforts to incorporate marginalized perspectives have led to a subsequent lack of inclusive, culturally sensitive definitions of support and support systems. The phenomenology around experiences, beliefs and perceptions is an integral component in describing support and support systems, where the composition and content of support systems depend on context and culture. Using archival qualitative research data from focus groups and ecomaps conducted with elementary school-aged children across 9 of the 14 international sites in the Promoting Psychological Well¬-Being Globally (PPWBG) project (Nastasi & Borja, 2016), the present research used children’s voices in identifying contextually-relevant sources of support, as well as patterns across 9 of the 14 sites. The present research was a part of a multi-method study, serving as a secondary analysis to triangulate (across two methods) previously analyzed data elicited from the focus groups (Borja et al., 2016) and ecomap tool (Borja et al., 2017). The goal of triangulation was to examine for consistent themes related to support and enhance the credibility of the combined tools’ ability to elicit data around support. The triangulation yielded 33 codes related to systems of support for psychological well-being¬. A thematic analysis condensed the codes into 5 broad themes: Financial/Material Support, Emotional Support, Social Support, Recreational Activities and Academic Support. These themes were salient across the nine sites. Ultimately, the five themes were either identified as being possibly global or context-specific, which may be useful in future research to inform practice and instrument development. / 1 / Sydney A.

An Engineering Decision Support System (EDSS) with alternative-criterion pair evaluations

Herling, Derald E. 24 April 1997 (has links)
An Engineering Decision Support System, EDSS, was developed using Bayesian mathematics which incorporates knowledge and confidence components observed in alternative-criterion pair decision making. The separation of knowledge and confidence has been previously unaccounted for in decision-making methods. EDSS provides decision support to individuals or teams which must make choices between alternatives using alternative-criterion pair evaluations. Further, EDSS was instanciated into computer software. The EDSS decision support system was statistically tested using two variables, mechanical experience of the participants and the use of a decision method, at two different levels and in a replicated factorial experiment. The experiment consisted of teams of subjects solving a simple mechanical design problem. Data from the experiment was collected for eighteen different metrics in four categories. This research reports on each of eighteen metrics using the hypothesis that the use of EDSS will show improvements in, or positive impact on, the following four categories: the decision making productivity of idea processing, the decision-making process, the perception of the decisions made by the decision makers, and the ease of use of a computer decision support tool. Statistical results of the experiment showed that EDSS successfully matched ad-hoc and Pugh's decision matrix performance for sixteen of the eighteen metrics and statistically exceeded the remaining two. These two metrics are, the conduction of more evaluations of alternative-criterion pairs ,and increased problem understanding. This research also shows that a new alternative-criterion pair evaluation method has been successfully created that provides for: - A separation of knowledge and confidence in the Belief Model of decision making. - Decision results without complete evaluation of all alternative-criterion pairs. - Aggregation of preferences from team members. - A convenient means for investigating decision improvements. / Graduation date: 1997
