Numerous studies and interventions have been designed to either reduce the prevalence of risky behaviors (substance use, sexual activity, etc.) or increase the level of educational activity for adolescents. Research suggests that these two constructs may be related yet little is known about this relationship among African American youth. Archival data from the Risk Reduction Project was used to explore the connection between the protective factors of educational aspirations/expectations and recent participation in risky behavior. Results suggest that recent use of marijuana, alcohol to the point of intoxication, and sexual activity predicted lower aspirations and expectations among African American youth. From a positive youth development perspective, this study suggests the development of holistic interventions that build educational assets in youth, in addition to working to minimize risk behaviors. Limitations and suggestions for future research are also discussed. 相似文献

The conventional sovereignty that has prevailed for the past several centuries restricts the options open to ethnic minorities
in multiethnic populations that are subject to a single sovereign authority. Minorities will either trend toward integration
with majority populations or else the direction of change will be toward separation and the establishment of new, smaller
sovereign states. There are serious problems with both options. The present proposal is for a form of diluted or “attenuated”
sovereignty whereby, in its most basic form, a particular ethnic minority would be afforded limited sovereignty in a specified
area within an existing sovereign state’s overall territory. An attenuated-sovereignty government established in the specified
area would be answerable to—and have authority over—only those persons of the designated ethnic minority who have opted to
affiliate themselves with it. Distinctive to this proposal, all other persons, irrespective of their ethnicity, could remain
in the delimited area and remain subject to the pre-existing, conventionally sovereign authority. This proposal includes various
strategies to make attenuated sovereignty a practical, workable option. The notion of attenuated sovereignty is not as fantastical
as it may seem at first glance. Re this assertion, the conventionally sovereign state is everywhere at bay. Its best days
are behind it. Under the circumstances, in some situations, attenuated sovereignty could prove advantageous to both ethnic
minorities and majority populations willing to accommodate them in the creative manner here proposed. 相似文献

Commercially available skin cleansing alcohol wipes and conventional swabs were investigated for their use as a universal sampling medium for the simultaneous collection of both organic and inorganic explosive residues. Six compounds with the potential to be encountered in casework [pentaerythritol tetranitrate (PETN), 2,4,6-trinitrotoluene (TNT), hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), triacetone triperoxide (TATP), ammonium nitrate, and sodium chlorate] were selected as representative target compounds. Quantities of these target compounds were deposited on four different substrates (glass, plastic, aluminium foil and laminate). Two chosen alcohol wipes demonstrated better overall performance in the recovery of both the organic and inorganic representative compounds from each of the test surfaces compared to the results obtained using conventional cotton and polyester swabs, pre-moistened with various solvents, and a direct methanol wash (used as a control). Results obtained using dry cotton swabs indicated that it was not an effective swabbing system for the collection of both organic and inorganic explosive residues on common substrates. 相似文献
