The paper provides a method for generating epoch estimates for time series survey data, allowing for different periods of time (or even point estimates) according to user demand. The method uses a modified kriging estimator, which suppresses the contribution of sampling error variability in order to guarantee that custom epoch estimates have an interpolation property. For the veteran population variable of the American Community Survey, we utilize a simple Brownian Motion model of the population process and derive the modified kriging estimator for this case. The tuning parameters of this population model can be calibrated to the data via simple formulas. We illustrate the application of this method to the generation of point estimates of veteran population, an important objective for Veterans Affairs. 相似文献

This paper introduces a novel avenue of study for understanding the mechanisms behind racial discrimination in law enforcement. I exploit a new 25‐year panel history of the race of every U.S. sheriff to shed light on the potentially important role of managers who make hiring decisions and set departmental priorities. Comparing agencies that experience racial transitions to agencies with overlapping jurisdictions reveals that the ratio of Black‐to‐White arrests is significantly higher under White sheriffs. Heterogeneity analysis indicates that the effects are driven by arrests for less‐serious offenses and by targeting Black crime types. (JEL J15, K42, M54, H76) 相似文献

Does race affect the route to downward mobility from white collar occupations? Data from Panel Study of Income Dynamics are used to assess the minority vulnerability thesis, which maintains there are race-specific processes of down ward occupational mobility among males from white collar occupations. Findings indicate that, consistent with theory, a racialized continuum exists across six years of the work-career. For Whites, the path to downward mobility is relatively narrow and structured by traditional stratification-based causal factors, namely, human capital, back ground socioeconomic status, and job/labor market characteristics. For African Americans, the route to downward mobility is broad-based and not captured by traditional stratification factors and Latinos occupy an intermediate ground between Whites and African Americans. Further, as predicted by theory, the racial gap in mobility processes between Whites and racial minorities is pronounced at the lower-tier of white collar employment. Finally, implications of the findings for understanding labor market inequalities on the basis of race are discussed. 相似文献

This study examines changes over time in ethnic affirmation/belonging and ethnic identity achievement, Spanish language use, English language use, Mexican/Mexican‐American affiliation/identification and Anglo affiliation/identification in a sample of Mexican‐American adolescents participating in a longitudinal study of juvenile offenders. The Multigroup Ethnic Identity Measure and the Acculturation Rating Scale for Mexican Americans‐II were completed by the Mexican‐American adolescents 7 times over a 3‐year period. The findings from longitudinal growth modeling analyses and growth mixture modeling analyses indicate that there is heterogeneity in the initial scores and changes over time on these variables that are related to markers for the cultural qualities of the home environment (i.e., generational status and mother's most frequent language use). In contrast to expectations, marginalized or assimilated acculturation trajectories/types were not overrepresented in this sample of adolescent offenders. Implications for our understanding of the nature of acculturation and enculturation processes and the way these processes are studied are discussed. 相似文献

Institutional theory suggests that organizations pursue legitimacyby conforming to isomorphic pressures in their environment.We extend previous research on institutional theory by distinguishingbetween two definitions of conformity (compliance and convergence)and by taking a comprehensive view of the organizational characteristicsthat might be subject to isomorphic pressures. This frameworkis applied to change between 2001 and 2004 in the internal characteristicsof 101 public organizations in England. We find substantialevidence of compliance but more limited support for convergence.Furthermore, the impact of isomorphic pressures was strongeron organizational strategies and culture than on structuresand processes. Thus, the relevance of institutional theory tochange in the public sector depends on the definition of conformitythat is used and the organizational characteristics that areexamined. 相似文献

ABSTRACTEngagement of individuals with serious mental illnesses in community mental health services is a significant challenge. The Program of Assertive Community Treatment (PACT) is an individual-centered and self-contained mental health program that provides psychiatric treatment, rehabilitation, and support services to persons with serious mental illness who have a history of or likelihood of disengagement with services. Understanding what helps and hinders consumers’ involvement in PACT services may provide information on how to tailor engagement strategies to individuals based on their treatment needs and preferences. The current study builds on existing studies by exploring factors that help and hinder engagement in PACT services from the perspectives of individuals receiving treatment. We conducted open-ended, semi-structured interviews with 17 individuals receiving PACT services. Nine themes were identified through thematic analysis: Desirable qualities of PACT, Focusing on positive outcomes, PACT as a safety net, Recovery orientation, Practical barriers, Conflictual relationships, and Medication side-effects. We conclude that the development of a trusting, therapeutic relationship that is collaborative and person-centered and that is facilitated by both practical and emotional support is critical to engaging individuals in treatment and maximizing positive outcomes. 相似文献

Studies from the West suggest that significant numbers of high school students gamble, despite it being illegal in this age group. To date, there have been no studies on the prevalence of gambling among senior high school and higher secondary school students in India. This study reports point prevalence of gambling and its psychosocial correlates among high school students in the State of Kerala, India. 5043 high school students in the age group 15–19 years, from 73 schools, were selected by cluster random sampling from the district of Ernakulam, Kerala, South India. They completed questionnaires that assessed gambling, substance use, psychological distress, suicidality, and symptoms of Attention Deficit Hyperactivity Disorder (ADHD). Of a total of 4989 completed questionnaires, 1400 (27.9 %) high school students reported to have ever gambled and 353 (7.1 %) were problem gamblers. Of those who had ever gambled, 25.2 % were problem gamblers. Sports betting (betting on cricket and football) was the most popular form of gambling followed by the lottery. Problem gamblers when compared with non-problem gamblers and non-gamblers were significantly more likely to be male, have academic failures, have higher rates of lifetime alcohol and tobacco use, psychological distress, suicidality, history of sexual abuse and higher ADHD symptom scores. Gambling among adolescents in India deserves greater attention, as one in four students who ever gambled was a problem gambler and because of its association with a range of psychosocial variables. 相似文献

Research has found gambling to be related to a variety of other addictive behaviours. The study objective was to evaluate the association of Internet gambling with Internet addiction, online sexual engagement, suicidality and substance use, in a sample of Greek adults. The study sample consisted of 789 military personnel. During their annual medical examination the study participants anonymously completed a series of self-reported questionnaires in relation to socio-demographic data, Internet gambling practices, online sexual engagement, Internet addiction, suicidality and psychoactive substance use. We found that Internet addiction significantly predicted engagement with online gambling, followed by substance use in general, and, in particular, the use of cocaine or heroin. Finally, two other predictive indicators were self-reported suicide attempts and engagement with online sex. Online gambling is associated with various behaviours related to impulsivity such as Internet addiction, online sexual engagement, suicidality and substance use. Future research will increase our knowledge on the contribution of new technologies and the Internet in Internet gambling dimensions, as well as on the associations with other high-risk behaviours such as substance use, pornography and suicidality. 相似文献
