On February 20 M. V. dc Korostovetz read a paper on Soviet Russia and her Southern Neighbours. The subject was divided into four parts: (a) The general trend of Russia's foreign policy, which, whether Imperial or Bolshevik, has differed in method rather than aim; (b) the States from Turkey to China, lying to the south of the Soviet block, with special attention to Chinese Turkestan; (c) the Ukrainian attitude to Communism; and (d) an outline of the new canals planned to make the Volga the chief waterway of Russia at the expense of the Don, and, with the refortification of the Straits, to turn the Black Sea into a mare clausum.  相似文献

Editor's note     
This study applies Elisabeth Noelle‐Neumann's spiral of silence theory to the controversial issue of whether children with AIDS should be allowed to attend public school. The study tests the theory's hypotheses in light of two content analyses of the media's treatment of the issue. The findings offer tentative and qualified support for Noelle‐Neumann's theoretical propositions about the relationship between individuals' perceptions of the issue and the media's tenor of the issue; particularly that of television. The findings suggest the need to address the role of other agents of influence, including reference groups, and to use time‐based data to unravel the causal order of the relationships.  相似文献

This article investigates how the struggles of national groups have affected the politics of bureaucratic representation of ethnic minorities in Belgium and Canada, and vice‐versa. It argues that the politics of multinational representation in Belgium limited the adoption of measures seeking to guarantee a greater representation of ethnic and racial minorities. In contrast, the politics of multiculturalism in Canada associated with the political mobilization of ethnic groups, contributed to the rejection of measures of guaranteed representation of Francophones in the federal bureaucracy. Measures adopted to increase the representation of Francophones, however, did not impede later attempts to augment representation of visible minorities in the civil service.  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.
