The Interpretation of Multiracial Status and Its Relation to Social Engagement and Psychological Well-Being

This research examines how multiracial individuals chose to identify themselves with respect to their racial identity and how this choice relates to their self-reported psychological well-being (e.g., self-esteem, positive affect) and level of social engagement (e.g., citizenship behaviors, group alienation). High school students who belong to multiple racial/ethnic groups (N = 182) were asked to indicate the group with which they primarily identify. Participants were then classified as identifying with a low-status group (i.e., Black or Latino), a high-status group (i.e., Asian or White), or multiple groups (e.g., Black and White, etc.). Results showed that, compared with multiracial individuals who identified primarily with a low- or high-status group, those who identified with multiple groups tended to report either equal or higher psychological well-being and social engagement. Potential explanations and implications for understanding multiracial identity are discussed.     

Improved switching rules in control procedures using variable sampling intervals

Some properties of control procedures with variable sampling intervals (VSI) have been investigated in recent years by Amin, Renolds et al, and others. Such procedures have been shown to be more efficient when compared to the corresponding fixed sampling interval (FSI) charts with respect to the Average Time to Signal (ATS) when the Average Run Length (ARL) values for both types of procedures are held equal. Frequent switching between the different sampling intervals can be a complicating factor in the application of control charts with variable sampling intervals (VSI). This problem is being addressed in this article, and improved switching rules are presented and evaluated for Shewhart, CUSUM, and EWMA control procedures. The proposed rules considerably reduce the average number of switches between the sampling intervals and also improve the ATS properties of the control procedures when compared to the conventional variable sampling interval procedures     

Small area estimation of poverty indicators

The authors propose to estimate nonlinear small area population parameters by using the empirical Bayes (best) method, based on a nested error model. They focus on poverty indicators as particular nonlinear parameters of interest, but the proposed methodology is applicable to general nonlinear parameters. They use a parametric bootstrap method to estimate the mean squared error of the empirical best estimators. They also study small sample properties of these estimators by model‐based and design‐based simulation studies. Results show large reductions in mean squared error relative to direct area‐specific estimators and other estimators obtained by “simulated” censuses. The authors also apply the proposed method to estimate poverty incidences and poverty gaps in Spanish provinces by gender with mean squared errors estimated by the mentioned parametric bootstrap method. For the Spanish data, results show a significant reduction in coefficient of variation of the proposed empirical best estimators over direct estimators for practically all domains.

A relational analysis of migration in old age: How transnational ties affect migration decisions

Recently, the role of personal ties in migration decisions has received considerable attention. However, this aspect has seldom been studied in the context of retirement. This paper addresses this gap by shedding light on the composition of personal networks, types of mobility patterns and retirement locations for four groups of older adults. To this end, two methodological approaches are employed: (1) a qualitative Social Network Analysis to examine the composition of older adults' personal networks and (2) thematic coding to analyse the relational aspects of migration decisions. This paper draws on 29 semi-structured interviews conducted in Spain and Switzerland in 2020 and 2021. The findings demonstrate that pre-retirement migration trajectories shape personal network composition. Moreover, personal ties play a critical role in older adults' mobility patterns and choices of retirement location. Overall, this study provides valuable insights into the impact of personal networks on migration decisions of older adults.     

Expectations,Aspirations, and Achievement Among Latino Students of Immigrant Families

ABSTRACT

This study examines the relationship between various measures of parental and student expectations and aspirations and math achievement among Latino 12th graders of immigrant parents in the Educational Longitudinal Study (ELS): 2002 database. Findings indicate parental expectations and aspirations were not significant predictors of student achievement after controlling for an index of covariates. Moreover, neither were student expectations, agreement between student and parent expectations, nor student perceptions of parental aspirations. The analyses of the secondary questions likewise indicated only one strong relationship between aspirations, expectations, and parents' time in the United States – parental aspirations and expectations.     

Age Cohort Differences in Sexual Behaviors Among Black Men Who Have Sex With Men and Women

Little attention has focused on generational or age-related differences in human immunodeficiency virus/sexually transmitted infection (HIV/STI) risk behaviors among Black men who have sex with men and women (BMSMW). We examined sexual risk behaviors between BMSMW ages 40 and under compared to over age 40. Analysis was conducted using Centers for Disease Control and Prevention (CDC)–sponsored intervention data among BMSMW in Los Angeles, Chicago, and Philadelphia (n = 546). Pearson’s chi-square tests were conducted to evaluate associations between age groups and behavioral outcomes. Logistic regression was used to evaluate the odds of behavioral outcomes by age group, adjusting for sexual orientation and study location, within strata of HIV status. HIV-positive BMSMW over age 40 had 62% reduced odds of having a nonmain female partner of HIV-negative or unknown status compared to those ages 40 and under (adjusted odds ratio [AOR] 0.38, 95% confidence interval [CI] = 0.15, 0.95). Among HIV-negative BMSMW, the older cohort was associated with greater odds of having condomless insertive anal intercourse (IAI) with most recent main male partner (AOR 2.44, 95% CI = 1.12, 5.32) and having a concurrent partnership while with their recent main female partner (AOR = 2.6, 95% CI = 1.10, 4.67). For both groups, odds of engaging in certain risk behaviors increased with increasing age. Prevention efforts should consider generational differences and age in HIV risks among BMSMW.     

Ecosystem services from converted land: the importance of tree cover in Amazonian pastures

Deforestation is responsible for a substantial fraction of global carbon emissions and changes in surface energy budgets that affect climate. Deforestation losses include wildlife and human habitat, and myriad forest products on which rural and urban societies depend for food, fiber, fuel, fresh water, medicine, and recreation. Ecosystem services gained in the transition from forests to pasture and croplands, however, are often ignored in assessments of the impact of land cover change. The role of converted lands in tropical areas in terms of carbon uptake and storage is largely unknown. Pastures represent the fastest-growing form of converted land use in the tropics, even in some areas of rapid urban expansion. Tree biomass stored in these areas spans a broad range, depending on tree cover. Trees in pasture increase carbon storage, provide shade for cattle, and increase productivity of forage material. As a result, increasing fractional tree cover can provide benefits land managers as well as important ecosystem services such as reducing conversion pressure on forests adjacent to pastures. This study presents an estimation of fractional tree cover in pasture in a dynamic region on the verge of large-scale land use change. An appropriate sampling interval is established for similar studies, one that balances the need for independent samples of sufficient number to characterize a pasture in terms of fractional tree cover. This information represents a useful policy tool for government organizations and NGOs interested in encouraging ecosystem services on converted lands. Using high spatial resolution remotely sensed imagery, fractional tree cover in pasture is quantified for the municipality of Rio Branco, Brazil. A semivariogram and devolving spatial resolution are employed to determine the coarsest sampling interval that may be used, minimizing effects of spatial autocorrelation. The coarsest sampling interval that minimizes spatial dependence was about 22 m. The area-weighted fractional tree cover for the study area was 1.85 %, corrected for a slight bias associated with the coarser sampling resolution. The pastures sampled for fractional tree cover were divided between ‘high’ and ‘low’ tree cover, which may be the result of intentional incorporation of arboreal species in pasture. Further research involving those ranchers that have a higher fractional tree cover may indicate ways to promote the practice on a broader scale in the region.     

A Peek Inside the Box: How Information Flows Through Substance Abuse Treatment Agencies

This article describes how integrated health information technology affects the collection and flow of client-level intake and assessment data within substance abuse treatment agencies. We combined process mapping and qualitative inquiry methods to analyze staff interviews (N = 54) from eight agencies in four U.S. states. Integrated health information technology was related to expedited and improved flow of information, while nonintegrated health information technology systems were associated with double data entry, multiple eligibility screenings, and different intake processes across levels of care. Process mapping is an effective tool to identify barriers to efficient client-level data management and opportunities to leverage health information technology to streamline the intake process of substance abuse treatment agencies, improve staff productivity, and enhance the accuracy and information flow.     

Maybe ignorance is not always bliss: The disparate treatment of Hispanics within the child welfare system

Previous studies indicate that the proportion of culturally diverse children to White children is increasing in public social service agencies. In addition, culturally diverse children are more likely to receive more intensive and punitive services, are more likely to stay within the system for longer periods of time and are reported more often to Child Protective Services. The purpose of the study was to explore how child welfare practices with Hispanic children are different from those applied with White non-Hispanic children. This study was a retrospective, two year, longitudinal, survival analysis of differential child welfare placement outcomes of White non-Hispanic and Hispanic children/families which had substantiated cases of abuse/neglect (n=1001).Findings demonstrate that although cases reported for abuse/neglect are relatively proportionate between Hispanic and White non-Hispanic children, substantiated cases are more likely to occur with Hispanic children. These children are more likely to be placed out of the home more quickly and for longer periods of time than their White non-Hispanic counterparts. The current study demonstrates the need for increased cultural awareness among Child Welfare professionals, especially in terms of assessment and case decision making, and the need for the development of culturally sensitive training modules for CPS and case management personnel.     

American Indian tribal government support of office-seekers: Findings from the 1994 election

How and why do American Indian tribal governments support political office-seekers? Using results from an extensive survey of tribal governments in Arizona and Oklahoma, our findings suggest that issues, rather than cultural ties or political party affiliation, are the primary impetus for American Indian tribal government support of candidates. Additionally, we examine several ways in which American Indians support candidates for office other than voting. This includes official endorsement, financial contributions, get out the vote efforts (GOTV), and volunteering for a candidate. Ultimately, our findings begin to uncover how and why American Indian tribal governments seek to influence the political process in the current era of evolving “government-to-government” relationships.
