African American males experience poor academic performance, high absenteeism at school, and are at increased risk of being involved in violence than other racial groups. Given that the educational outlook for African American males appears bleak, it is important to assess the aspirations of these adolescent males in order to find the gap between aspirations and educational attainment. In order to promote positive development within this population, it is essential that factors that affect African American males be identified. A survey was administered to male students attending elementary, middle, and high schools in a local school district. A cross-sectional study was conducted to examine the career and educational aspirations of African American males. A total of 473 males were surveyed: 45% African American, 22% Caucasian, 13% biracial, and 19% Other (including Asian American, Hispanic, Native American). The results revealed that African American males aspired to attend college at the same rate as other ethnic groups. Also, African American males were more likely to aspire to be professional athletes than males from other ethnic groups. Important factors to consider when designing a program are discussed as well as future research and limitations. 相似文献

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

Sub‐national government capital spending is important for both public service delivery and economic development. Currently, Indonesian sub‐national public capital spending appears barely sufficient to cover the annual depreciation of its fixed assets. A substantial proportion of local government investment spending goes to create relatively unproductive assets, such as administrative office buildings. Sub‐national governments finance their capital acquisitions out of gross operating budgets and have thus far not used, to any great extent, either borrowed funds or their significant cash reserves for such purposes. Indonesian sub‐nationals need to spend more on capital than they do now and also need to focus that spending on more useful types of infrastructure. The major constraints to increasing capital spending at the sub‐national level are not related to a dearth of finance, but regulatory rigidities in budget preparation and implementation and, most importantly, a lack of capacity to plan, design and implement investment projects.

The cost of civil litigation is a key factor in determining the extent of access to justice. Following cuts in legal aid attention has focused upon finding alternative methods of assisting litigants without producing costs which are out of proportion to the damages obtained. The recent report by Lord Justice Jackson attempts to deal with concerns about increasing and disproportionate costs said to arise in part because of the encouragement of conditional fee agreements. This article considers the proposals made in the report, and argues that too little attention has been paid to before‐the‐event insurance as a means of securing access to justice for the great majority of claimants who suffer personal injury. 相似文献

Methadone is a potent analgesic and sedative. It is widely used in the treatment of heroin addiction and is often encountered in forensic specimens. In electron impact (EI) gas chromatography/mass spectrometry (GC/MS) mode, methadone produces predominantly a m/z 72 ion, which is not sufficiently characteristic for identification. Determination of the molecular ion, which can be achieved using chemical ionization (CI) provides diagnostic information and better identification of the drug. This paper describes the development of a positive ion CI GC/MS procedure, using a liquid reagent gas and ion trap instrumentation, for the determination of methadone and its metabolites in urine. CI generally produces a single molecular ion spectrum, but optimization of the reagent gas parameters increases the fragmentation of the molecule, allowing determination of ion ratios if required. The procedure is sensitive, diagnostic and is currently in routine use in our laboratory. 相似文献

Establishing the biological sex of human remains is a very important part of identifying victims of fire when severe soft tissue destruction has occurred. Deciduous (children's) teeth were exposed to a range of incineration temperatures 100-500 degrees C for 15 minutes. Polymerase Chain Reaction (PCR) amplification was used to identify specific human amelogenin regions. There was successful identification of human biological sex, from deciduous teeth exposed to incineration temperatures of 200 degrees C and below, using standard ethidium bromide gel staining. There was greater sensitivity using fragment analysis by laser induced fluorescence which achieved sex identification from some teeth heated to 400 degrees C. 相似文献

Does the president or Congress have more influence over policymaking by the bureaucracy? Despite a wealth of theoretical guidance, progress on this important question has proven elusive due to competing theoretical predictions and severe difficulties in measuring agency influence and oversight. We use a survey of federal executives to assess political influence, congressional oversight, and the policy preferences of agencies, committees, and the president on a comparable scale. Analyzing variation in political influence across and within agencies reveals that Congress is less influential relative to the White House when more committees are involved. While increasing the number of involved committees may maximize the electoral benefits for members, it may also undercut the ability of Congress as an institution to collectively respond to the actions of the presidency or the bureaucracy. 相似文献

To what extent do presidents select appointees based upon campaign experience and connections? The answer to this question has important implications for our understanding of presidential management and political leadership. This article presents a theory explaining where presidents place different types of appointees and why, focusing on differences in ideology, competence, and non‐policy patronage benefits among potential appointees. We develop a formal model and test its implications with new data on 1,307 persons appointed in the first six months of the Obama administration. The empirical results broadly support the theory, suggesting that President Obama was more likely to place appointees selected for non‐policy patronage reasons in agencies off his agenda, in agencies that shared his policy views, and where appointees are least able to affect agency performance. We conclude that patronage continues to play an important role in American politics, with important consequences for campaigns, presidential politics, and governance. 相似文献
