Racial and ethnic differences in marriage outcomes are well established in the previous literature. In addition, variation in the social structure in which individuals reside has an impact on the context in which mate selection and marriage occur. The purpose of this dissertation is to determine how these variations shape marriage outcomes for Non-Hispanic Whites, Non-Hispanic Blacks, Hispanics and Non-Hispanic Asians. Beyond racial and ethnic characteristics, this series of studies take into account temporal metropolitan characteristics. Study 1 uses U.S. Census and American Community Survey data to predict metropolitan marriage prevalence at three time points: 1990, 2000 and 2010. Study 2 predicts the odds that individuals across the four racial/ethnic groups have never married, taking into account structural characteristics including region of residence. Study 3 predicts the odds that currently married women are racially or ethnically intermarried, with emphasis on race/ethnicity and region of residence. The results suggest that metropolitan structural characteristics matter somewhat, but individuals' race/ethnicity is the strongest predictor of both the odds of having never married and intermarriage. There is also evidence that region serves as a moderator impacting the overall marriage outcomes of racial/ethnic minority groups to a greater extent in comparison to Non-Hispanic Whites.

The main purpose of this dissertation is to examine the effects of migration and household capitals on agricultural and energy transitions in the setting of rapidly changing socioeconomic and environmental conditions of Chitwan, Nepal. The environmental aspects of agricultural and energy transitions are also discussed to weave the changes in the livelihoods of rural households into the discourse of sustainable development, especially in the context of underdeveloped countries. The data used for the analysis is the Chitwan Valley Family Study which has been collected since 1996 at the individual and household level with the focuses on agriculture and family. The results from first difference model and multilevel logistic regression model using discrete-time event history approach deliver a couple of important messages for the future plans for local and national development. Most of all, migration plays an important role in the livelihoods of rural households in Chitwan. It might not have a direct impact, but the findings indicate that social and financial remittances from migration interact with how a household utilizes their current capitals under a given context for the future. Particularly, available labor in a household, prior investment in agriculture, exposure to modern life style, and what other people do, all these factors moderate the association between migration and the transitions. The implications of these results on sustainable development for the future of Chitwan and Nepal in the coming years are discussed afterwards.

This dissertation explored how immigrants cope with and thrive in old age by utilizing social networks, and the hindrances which may prevent this. Through ethnographic fieldwork and in-depth interviews at two senior centers in Phoenix, Arizona with a high concentration of an ethnic minority group - Asian and Latino, I describe what makes the Asian dominant center more resource abundant than its Latino counterpart given prevalent tight public funding. Both centers have a large number of seniors disenfranchised from mainstream institutions who bond together via similar experiences resulting from shared countries/regions of origin, language, and migration experience. The Asian center, however, is more successful in generating and circulating resources through "bonding" and "bridging" older immigrants who, therefore benefit more from their center affiliation than the Latinos at their center.

The abundance of resources at the Asian center flowing to the social networks of seniors are attributed to three factors: work and volunteer engagement and history, the organization of the center, and individual activities. At both centers seniors bond with each other due to shared ethnicity, language, and migration experience and share information and companionship in the language in which they feel most comfortable. What differentiated the two centers were the presence of several people well connected to individuals, groups, and institutions beyond the affiliated center. The presence of these "bridges" were critical when the centers were faced with budgetary constraints and Arizona was experiencing the effect of ongoing immigration policies. These "bridges" tend to come from shared ethnicity, and better social positions due to cumulative factors which include but are not limited to higher education, professional occupation, and work and volunteer history. I have also presented cases of individuals who, although have developed expertise from past work experiences and individual activities, have limited contribution to the resource flow because of the differences in ethnicity. The study also explored a gendered life course and its impact on the social network for older Asian and Latino immigrants.

The adaptation and integration of the mainstream and ethnic culture are important processes to understand as they have been associated with immigrant and minority youth's adjustment and family dynamics. However, few studies focusing on youth's cultural experiences have explored youth's active role in their own cultural development, and even less have explored youth's role in influencing parents' cultural development. In the current dissertation, two studies addressed these issues by using a within-family longitudinal design to explore 246 Mexican American youth's role in their own and their families' cultural development. The first study examined the reciprocal associations in parents' and two offspring's cultural values to examine developmental differences in parent-youth socialization processes. Overall, the importance of mothers' values was highlighted as a significant predictor of increases in youths' values, five years later. In addition, Study 1 highlighted situations where youth play an active role in their parents' cultural development as youths' lower endorsement of respect for elders values was associated with increases in fathers' value endorsement, five years later. The second study explored the associations between youth's imitation and de-identification from parents and parent-youth incongruence in Mexican and Anglo cultural orientations. Youths' active role in their cultural development was underscored, as youths' reports of de-identifying from parents were linked to more incongruence in parent-youth Anglo orientations. Further, important family characteristics (i.e., parent-youth warmth and demographic similarities) were shown to predict youths' more imitation and less de-identification from parents.
