Growing divisions between Britain’s towns and cities have created a dilemma for the Labour Party in seeking to represent very different parts of the country. There are some who argue that Labour must choose the global networked youth—who largely reside in cities—in order to maximise its electoral chances. This is an argument that defies electoral gravity and fails to address the root causes of the gulf between towns and cities. As jobs and investment have gone into cities, many towns have seen the local population age and local economies become unsustainable. In both towns and cities there is a clamour for power to move closer to home and for the renewal of democratic institutions, offering Labour the chance to win power and end the divisions that have come to characterise British politics.  相似文献

This study examined the construct validity of antisocial personality disorder (ASPD) diagnosed in adolescence. Boys and girls were grouped by history of DSM-III-R conduct disorder (CD) and ASPD: Controls (n=340) had neither diagnosis; CD Only (n=77) had CD by age 17 but no ASPD through age 20; Adolescent ASPD (n = 64) had ASPD by age 17. The Adolescent ASPD group was then compared to 20 young adult men who met criteria for ASPD (ASPD group). As expected, the Adolescent ASPD group had significantly more depression and substance use disorders, a greater performance>verbal IQ discrepancy, more deviant peers, and poorer academic functioning than the CD Only group and Controls. The Adolescent ASPD and ASPD groups did not differ on most variables. Results support the construct validity of Adolescent ASPD and suggest that such a diagnosis could help identify adolescents at risk for persistent antisocial behavior.

The direct and mediated effects of socioenvironmental risk on internalizing and externalizing problems among Latino youth aged 10–14 were examined using prospective analyses. Participants in this study were 464 Latino mother and child dyads surveyed as part of the Welfare, Children & Families: A Three City Study. It was hypothesized that socioenvironmental risk (i.e., maternal psychological distress, maternal parenting stress, neighborhood disadvantage, and perceived financial strain) would influence later adolescent adjustment by interrupting important family processes and interfering with opportunities for adolescents to develop appropriate social competence. Using path analyses, the mediational model was compared across high and low acculturation groups. With two exceptions, the models for the high and low acculturation groups were equivalent. Results supported a mediated effect between early socioenvironmental risk and later adjustment problems for the low acculturation group through family routines and adolescent social competence. Among families high in acculturation, socioenvironmental risk effects were partially mediated through family routines and adolescent social competence. Finally, a path from gender to maternal monitoring was present in the low acculturation group model but not the high acculturation group model.

Tumescent liposuction is a common cosmetic procedure that is performed as an outpatient service in physician's offices and is largely believed to be safe. The protuberant areas of the body containing the undesirable fat deposits are injected with normal saline containing lidocaine and epinephrine for pain control and hemostasis, and the waterlogged cells are suctioned out via cannula through a small incision. We recently encountered three cases in which deaths were attributed to this procedure. Two showed fat embolization in the lung and one died from fluid overload. The osmium tetroxide post-fixed lung sections showed fat emboli in the interstitial capillaries and arterioles. We reviewed the recent literature and found that pulmonary thromboemboli, fat embolization, fluid overload, and lidocaine and epinephrine intoxication are found at autopsy in many cases. Forensic pathologists responsible for determining the cause and manner of death should become familiar with the postmortem findings and risks of liposuction therapy and communicate them to their clinical colleagues and communities.  相似文献

Political knowledge is a powerful predictor of political participation. Moreover, what citizens know about the political system and its actors is a central aspect of informed voting. This article investigates how and why political knowledge varies between citizens. The analysis is comparative and based on data from the Comparative Study of Electoral Systems. At the micro level, the results confirm results from national surveys – specifically that education explains what citizens know about politics. It is found in a contextualized analysis, however, that the effect of education varies with the country's degree of economic redistribution. In more egalitarian countries, political knowledge is less contingent on education attained than in more inegalitarian countries. Similarly, education seems to have a stronger effect in countries with majoritarian electoral systems compared to countries with proportional systems.  相似文献

This longitudinal study investigates parent and child predictors of adolescents' perceived social support from peers. Adolescents (285) and their parents filled out surveys when students were 11 and 15 years of age. Parent reports of their own social support and child reports of parental support to them, depression, and self-esteem were used as predictors of adolescents' peer social support. Path analyses revealed functional dissimilarity in the predictive model, for boys and girls. For boys and girls, the amount of spousal support parents' reported impacted the amount of parent to child support that children reported. For boys, this relationship impacted their perceptions of peer support indirectly through depression. However, for girls, parents' own supportive relationships directly impacted both their self-esteem and depression, above and beyond parent to child support, which then impacted girls' peer social support.  相似文献
