What Makes an Adult? Examining Descriptions from Adolescents of Divorce   总被引:2,自引:0,他引:2  
The present study examined conceptions of “what makes an adult” within a sample of adolescents (13–19 years) from divorced families. Arnett’s (2003) seven criteria-of-adulthood categories (independence, interdependence, role transitions, norm compliance, biological transitions, chronological transitions, and family capacities) were used as an initial framework for grouping open-ended written responses, while inductive content analysis was employed to analyze all other responses. Although the majority of responses (N=568) fit into Arnett’s categories, 35.2% of responses were coded into eleven newly created categories (e.g., knowledge/wisdom, role model/leader). The present study confirmed that independence qualities are believed to be most important. However, role transitions (e.g., marriage) were considered more significant than in previous research. The qualitative findings and their specific pattern should inform existing quantitative measures of adulthood criteria. Doctoral Student at the University of Arizona.

Adult sexual dimorphism is well established. However, data regarding fetuses are sparse with contradictory results. Our study aimed to look for fetal sexual dimorphism. Multislice computed tomography (MSCT) examinations and three‐dimensional (3D) reconstructions were recorded on 93 fetal iliac bones aged between 21 and 40 weeks of amenorrhea (WA). The collection was divided into two age groups, with a cutoff at 30 WA. The 3D geometric morphometric analysis was based on outline analysis. We used elliptic Fourier analysis (EFA) because of the difficulty of landmark positioning. Step‐by‐step reconstructions allowed a better comprehension of the fine shape details. Principal component analysis (PCA) and linear discriminant analysis (LDA) were performed on the two age groups. Results did not show any difference between male and female shapes, in both age groups. We demonstrate the feasibility of outline analysis for immature shapes, but sexual dimorphism has not been established in our collection.  相似文献

This article examines the self-positioning of the three Baltic states in international politics in relation to the major structural pressures challenging the status quo of the transatlantic security configuration. The constitutive role of the Russia-Georgia war of 2008, the global economic recession, the debt crisis in the eurozone, and the shifting policy preferences and force projection of the United States towards Asia are explored as the key sources of the emerging Baltic security predicament. The empirical conclusions of the poststructuralist discourse analysis conducted for this study demonstrate how the Baltic states, in particular Estonia, have recently come to redefine the contents of ‘new’ Europe, thereby shifting the extant fault lines within the European Union.  相似文献

The article sets out to investigate Germany's involvement in the controversial 2009 Kunduz air strike in Afghanistan. Utilizing a theoretical framework derived from existing literature on postheroic warfare, it employs a detailed case study of this particular military engagement to highlight the operational, strategic, and cultural dimensions of Germany's operations in Afghanistan. Through an analysis of primary documents and field interviews, this paper concludes that German public opinion, politicians, soldiers and media reacted in ways that mirror closely theories of postheroic warfare. These included widespread condemnation of the air strike, increasing doubts about the Afghan mission, and emphasis on low-risk stand-off precision weapons, which paradoxically resulted in higher civilian casualties. Germans still have a long way to go to accept the brutal realities of military engagements that the Bundeswehr increasingly confronts during its expanded scope of post-cold war military operations.  相似文献

Brownridge and Halli (1999) have argued that the literature on family violence is beset by confusion in the conceptualization and utilization of incidence and prevalence terminology. Although we basically agree with the authors' diagnosis of the field, definitions of prevalence and incidence that they propose as gold standards are sometimes discrepant with established concepts in epidemiology. Drawing on the epidemiologic literature, we present more solidly based and operational definitions of these terms and try to understand the meaning of each measure. The same confusion surrounding use of prevalence and incidence also reigns in child maltreatment research, as revealed in our review of major studies. We address some of the main but often overlooked issues associated with use of epidemiologic measures in an area of social research such as family violence and make some proposals.  相似文献
