Although lesbian, gay, and bisexual (LGB) youth with a history of homelessness (running away or being evicted from their homes by parents) report more psychological symptoms than homeless heterosexual peers, it is unclear whether symptoms are due to homelessness, given the absence of a non-homeless comparison group. This study longitudinally investigates whether LGB youth with a history of homelessness report more subsequent psychological symptoms than non-homeless LGB youth and examines potential mediators of any such relationships. Of the 156 LGB youth interviewed (49% female; 78% non-White), 48% reported past homeless experiences. Homelessness was associated with subsequent symptoms of anxiety, depression, conduct problems, and substance abuse and to changes in symptoms over time even after controlling for childhood sexual abuse and early development of sexual orientation. Stressful life events, negative social relationships, and social support from friends mediated the relationships between homelessness and symptomatology. These findings suggest the need for interventions to reduce stress and enhance social support among LGB youth with a history of homelessness in order to reduce psychological symptoms.  相似文献

This cross-sectional study tests a conceptual financial socialization process model, specifying four-levels that connect anticipatory socialization during adolescence to young adults’ current financial learning, to their financial attitudes, and to their financial behavior. A total of 2,098 first-year college students (61.9% females) participated in the survey, representing a diverse ethnic group (32.6% minority participation: Hispanic 14.9%, Asian/Asian American 9%, Black 3.4%, Native American 1.8% and other 3.5%). Structural equation modeling indicated that parents, work, and high school financial education during adolescence predicted young adults’ current financial learning, attitude and behavior, with the role played by parents substantially greater than the role played by work experience and high school financial education combined. Data also supported the proposed hierarchical financial socialization four-level model, indicating that early financial socialization is related to financial learning, which in turn is related to financial attitudes and subsequently to financial behavior. The study presents a discussion of how the theories of consumer socialization and planned behavior were combined effectively to depict the financial development of young adults. Several practical implications are also provided for parents, educators and students.  相似文献

Postmortem fingerprint collection is a routine part of many forensic death investigations. Although the production of postmortem prints is usually straight forward, several obstacles and scenarios can make the collection difficult. A common challenge occurs when finger pads are mummified. Several current techniques allow for softening and rehydration of mummified finger pads; however, despite the employment of such techniques, the production of adequate postmortem fingerprints can remain elusive. The authors present two techniques that can improve the chances of obtaining suitable fingerprints from mummified remains. The “baby powder method” involves applying a cornstarch‐based powder, such as baby powder, onto the darkened and mummified finger pads, to allow better visualization of the fingerprint detail. The “transillumination method” involves carefully dissecting away the tissues underlying the finger pad, followed by placement of a bright light source underneath the finger pad, such that the finger ridge pattern is illuminated.  相似文献

The distribution of cutaneous contusions in infants may raise the possibility of maltreatment. Neck contusions are particularly problematic since they seldom occur outside the setting of abuse, while cardiopulmonary resuscitation (CPR)‐related maneuvers may involve the neck. To address the role of CPR in neck findings, we examined 260 consecutive pediatric autopsies in which CPR was attempted. No neck contusions were identified in manners of death classified as natural, undetermined, or suicide. Contusions were present in two of 80 deaths classified as accident and had obvious accidental causes. About 26% of deaths classified as homicide had neck contusions with no explanation provided by the caregiver (p < 0.0001). In conclusion, neck contusions in deceased children with no apparent explanation should be regarded as suspicious for abuse and investigated accordingly. CPR is not a plausible explanation for neck contusions in children.  相似文献
