This study examined the asset ownership of Asian immigrants using a nationally representative sample of newly legalized immigrants (New Immigrant Survey). Findings revealed that ownership of a business or farm, financial assets, and home ownership were associated with socioeconomic, demographic, and acculturation variables. Family income, education, English fluency, and length of stay were significant in all types of asset ownership. Variances in asset ownership by ethnic groups exist. Asian Indians and Koreans had higher levels of business asset ownership. Korean, and Filipino immigrants were also more likely to be homeowners. Asian Indian and Chinese immigrants were more likely to own financial assets. Vietnamese lagged in business or farm and financial asset ownership. Findings provided insights into the investment decisions of new Asian immigrants for financial educators, researchers, and policymakers. 相似文献

The International Citicoline Trial in acUte Stroke is a sequential phase III study of the use of the drug citicoline in the treatment of acute ischaemic stroke, which was initiated in 2006 in 56 treatment centres. The primary objective of the trial is to demonstrate improved recovery of patients randomized to citicoline relative to those randomized to placebo after 12 weeks of follow-up. The primary analysis will take the form of a global test combining the dichotomized results of assessments on three well-established scales: the Barthel Index, the modified Rankin scale and the National Institutes of Health Stroke Scale. This approach was previously used in the analysis of the influential National Institute of Neurological Disorders and Stroke trial of recombinant tissue plasminogen activator in stroke.The purpose of this paper is to describe how this trial was designed, and in particular how the simultaneous objectives of taking into account three assessment scales, performing a series of interim analyses and conducting treatment allocation and adjusting the analyses to account for prognostic factors, including more than 50 treatment centres, were addressed. 相似文献

This article explores the relationship between kinship institutions and sex ratios in India at the turn of the twentieth century.
Because kinship rules vary by caste, language, religion, and region, we construct sex ratios by these categories at the district
level by using data from the 1901 Census of India for Punjab (North), Bengal (East), and Madras (South). We find that the
male-to-female sex ratio varied positively with caste rank, fell as one moved from the North to the East and then to the South,
was higher for Hindus than for Muslims, and was higher for northern Indo-Aryan speakers than for the southern Dravidian-speaking
people. We argue that these systematic patterns in the data are consistent with variations in the institution of family, kinship,
and inheritance. 相似文献

This article investigates the effect of family life course transitions on labor allocation strategies in rural Chinese households.
We highlight three types of economic activity that involve reallocation of household labor oriented toward a more diversified,
nonfarm rural economy: involvement in wage employment, household entrepreneurship, and/or multiple activities that span economic
sectors. With the use of data from the China Health and Nutrition Survey (CHNS 1997, 2000, and 2004), our longitudinal analyses
of rural household economic activity point to the significance of household demography, life course transitions, and local
economic structures as factors facilitating household labor reallocation. First, as expected, a relatively youthful household
structure is conducive to innovative economic behavior. Second, household entrances and exits are significant, but their impacts
are not equal. Life events such as births, deaths, marriage, or leaving home for school or employment affect household economy
in distinctive ways. Finally, the reallocations of household labor undertaken by households are shaped by local economic structures:
in particular, the extent of village-level entrepreneurial activity, off-farm employment, and out-migration. 相似文献

Consumers in many countries often give voluntary payments of money (tips) to the workers who have served them. These tips are supposed to be a reward for service and research indicates that they do increase with customers’ perceptions of service quality. This paper contributes to the service-tipping literature by examining numerous potential moderators of this relationship in two studies. Results indicate that the service-tipping relationship is robust across meal type, day of week, sex and race of server as well as customers’ alcohol consumption, education, income, race, worship frequency, and hospitality work experience, but that it is stronger for older consumers than for younger ones and for parties with large bills than for parties with smaller bills. The practical and theoretical implications of these and other findings are discussed. 相似文献

Girls in foster care may face difficulties across the transition to middle school. Latent growth curve modeling was employed to examine trajectories and predictors of academic competence and aggression from and against peers for 75 girls in foster care from the end of elementary school to the 2nd year of middle school. Across the transition to middle school, academic competence increased. Poor self-regulation was associated with decreased academic competence, and higher caregiver support was associated with increased academic competence. Frequency of aggression from peers decreased across the transition, with perceived school competence predicting smaller decreases. Aggression against peers dropped initially and then increased to pretransition levels by the end of the 2nd year of middle school. Lower caregiver support was associated with higher rates of aggression against peers at the end of the 1st year of middle school. The results are discussed in terms of implications for interventions for girls in foster care. 相似文献

We examine the utilization of remittances for expenditures associated with development, specifically children's education. We use household-level data from the Nepal Living Standards Survey (NLSS II, 2003–04) to separate remittance effects from general household income effects to demonstrate the migration–development relationship reflected in child schooling investment. We find that family-household remittances are spent on education of children, but the expenditures are disproportionately for boys' schooling. Only when girls are members of higher-income households do greater schooling expenditures go to them. This gender-discriminating pattern at the household level contrasts with the call for universal and gender-equal education. 相似文献

This study investigated the extent to which social support mediates negative effects of stalking and obsessive relational intrusion (ORI) victimization. A survey of 1,068 respondents indicated that (a) ORI/stalking victimization is positively related to negative symptoms and trauma; (b) five different types of coping responses are positively related to negative symptoms; (c) four domains of social support reveal small but significant negative relationships with negative symptoms; and (d) females are more threatened by unwanted pursuit than male victims, and male pursuers are more threatening than female pursuers. Structural equation modeling indicates that the influence of ORI/stalking on negative symptoms is mediated by the use of coping strategies and the adequacy of social support. Discussion speculates on the functional theoretical value of coping and support processes in managing unwanted pursuit and stalking. 相似文献

The purpose of the present study is to review empirical evidence of the effects of interventions designed to improve engagement
in mental health services among adolescents, young adults and their families. Investigators searched relevant databases, prior
reviews, and conducted hand searches for intervention studies that met the following criteria: (1) examined engagement in
mental health services; (2) included a comparison condition; and (3) focused on adolescents and/or young adults. Effect sizes
for all reported outcomes were calculated. Thirteen studies met inclusion criteria. Conceptualizations of engagement and measurement
approaches varied throughout studies. Approaches to improving engagement varied in effectiveness based on level of intervention.
Individual level approaches improved attendance during the initial stage of treatment. While family level engagement interventions
increased initial attendance rates, the impact did not extend to the ongoing use of services, whereas service delivery level
interventions were more effective at improving ongoing engagement. The review illuminated that engagement interventions framed
in an ecological model may be most effective at facilitating engagement. Implications for future research and practice are
discussed. 相似文献

The proliferation of lotteries and casinos has led to increased participation in gambling. Older adults who have opportunities to gamble may be vulnerable to gambling problems, and incarcerated older adults may be the most vulnerable. Furthermore, research has linked decreased health to gambling problems. This study compared perceived health and gambling problems among 43 incarcerated older adults from two county jails in the midwestern United States. Results from the South Oaks Gambling Screen indicated 48.83% of the sample scored in the problem or pathological range. Short Form-36 results were compared with U.S. norms for ages 55 to 64 and showed significantly lower perceived health scores on Role-Physical, Bodily Pain, Mental Health, Social Functioning, and Role-Emotional subscales. The problem and pathological gamblers showed significantly lower social functioning than the recreational gamblers. Assessment of health conditions and gambling behaviors is important for quantifying current and anticipated burdens of these conditions on correctional health care systems and the community. 相似文献
