Over the past few decades researchers have begun to examine the importance of understanding positive youth development and the many contexts in which youth find themselves. The social contexts in which adolescent development occurs are varied and complex, particularly the development among African American youth. African American youth are faced with a number of challenges including living in single-parent homes, high teen pregnancy rates, and poor neighborhoods, yet many of these youth continue to thrive. The purpose of this study was to examine the relationship between family structure (single-parenting) and adolescent outcomes such as educational aspirations and sexual activity among African American adolescent youth aged 12–17. Approximately 462 African American youth were surveyed. A number of positive results emerged; for instance, there was a negative correlation between family structure and educational aspirations. The number of parents in the home did not interfere with youth wanting to complete high school and go on to college (r = ? .218, r² = .04, p < .05). The results also showed that as educational aspirations increased, the number of sexual partners decreased (r = ? .141, meaning that the more adolescents reported a desire to complete high school, they were less likely to report having sexual intercourse. These positive results should be promoted among African American youth so that those faced with these challenges will note that others have overcome and accomplished their goals. In this population educational aspirations were important. Limitations and future research are discussed. 相似文献

The purpose of this article was to assess the overall health behaviors of African American emerging adults who live in a Midwestern city. Two hundred participants, ages 18–25, completed a 129-item survey. Results indicate that African American emerging adults are engaged in relatively healthy behaviors (i.e., physical activity, low substance use). The results also showed that within the emerging adult developmental period, there are differences in behavior for those who are in the younger (18–20) versus those that are older (21–25) in the developmental period. Limitations, future research, and implications for practice will also be discussed. 相似文献

Abstract The ‘flexicurity’ strategy reached the top of the European Union's policy agenda in the mid-2000s. The strategy assumes an adult worker model family and aims to promote better, as well as more, jobs and to ensure that policies should further both flexibility in the labour market and security for workers. The article explores, first, the meaning of internal and external flexibility, and of employment-based security and the different implications for men and women. While the policy documents assume that flexicurity will increase gender equality, the mechanisms have not been specified. In fact, as the article shows, women are often more ‘flexible’ workers than men, particularly regarding their contractual arrangements and hours of employment. However, they tend not to be economically autonomous and, we argue, the supply-side policies advocated on the security side of the flexicurity matrix are insufficient to improve their position, which is strongly related to the gendered divisions of paid and unpaid work. 相似文献

It is argued that leaders and other change agents will be able to transform organizations and the members of organizations only if they possess compelling explanatory frameworks for viewing organizational behavior, structure and dynamics. To illustrate this point, the stratified systems theory of Elliott Jaques is presented in the context of an organizational intervention. The “vision” promoted by stratified systems theory enabled an outside consultant to transform the leadership of an ailing social services agency and was useful in explaining the inability of the organization's administrator and board of directors to act transformationally during a period of rapid change 相似文献

The article addresses a deficiency in previous studies of city managers role behavior: the lack of a comprehensive, multidimensional typology through which such behavior might be categorized and explained. Utilizing factor scores generated from a list of fifteen questions in an I.C.M.A. survey questionnaire, the author uses a hierarchial grouping technique to produce seven profiles of managers role behavior. Personal, environmental, and attitudinal correlates are examined to round out each profile. 相似文献

The Organization for Security and Cooperation in Europe (OSCE) and the Shanghai Cooperation Organisation (SCO) represent competing sets of international norms in Central Asia. The contestation between these sets of norms has not led to a complete polarisation between members of the two organisations, however. Instead, the OSCE has used a range of discursive tactics to reduce political contestation, downplaying some contested issues and seeking shared discourses on security threats. This article explores these tactics and suggests that these discursive shifts may eventually threaten the normative identity of the OSCE and lead to the acceptance of a more hybrid set of security-related norms in the region. 相似文献

Abstract: Denaturing high-performance liquid chromatography (DHPLC) was evaluated as a sequencing-independent means of detecting the presence of sequence differences in pair-wise mixtures of nonconcordant amplicons of human mitochondrial DNA (mtDNA). A total of 920 pair-wise combinations of HV1 and HV2 mtDNA amplicons from 95 individuals were assayed by DHPLC for sequence concordance/nonconcordance. For the 72 combinations of amplicons from different individuals who shared identical DNA sequences, DHPLC assays consistently indicated sequence concordance between the samples. This was in 100% agreement with sequencing data. For the 849 combinations of amplicons which differed in sequence, DHPLC detected the presence of sequence nonconcordance in all but 13 assays to yield 98.5% concordance with sequencing. Thus, DHPLC can be used to detect a diversity of sequence differences (transitions, transversions, insertions, and deletions) in the mtDNA D-loop. Accordingly, DHPLC may have utility as a presumptive indicator of mtDNA sequence concordance samples, as a screen for heteroplasmy/situational mixtures, and as a means for the physical fractionation of the individual contributors to an mtDNA mixture prior to sequencing. 相似文献
