By dividing political power between the national governmentand multiple constituent governments, a federal system automaticallyproduces relations among the constituent governments. This articledescribes six provisions of the U.S. Constitution for handlingrelations between the states: (1) federal judicial settlementof interstate disputes, (2) cooperative action by states, (3)privileges and immunities within each state for out-of-statecitizens of the United States, (4) full faith and credit forthe public acts, records, and judicial proceedings of each state,(5) interstate rendition, and (6) free interchange of commerceamong the states. 相似文献

Ronald Reagan defined his federalism program in terms of returningpolitical power to state and local governments. In practice,he was Janus-faced with respect to his views on domestic policyissues. His "public" face emphasized initiatives promoting areturn of political power to the states and local governments.His "silent" face encouraged additional centralization of politicalpower in several functional areas, and he signed bills prohibitingstate economic regulation of certain industries. Most of Reagan'sinitiatives were administrative, and increased to a limitedextent the discretionary authority of states. In general, thepresident favored a smaller federal regulatory role but notnecessarily a larger state and local government role. He signedtotal preemption bills granting greater freedom of action tothe banking, communications, and transportation industries,and tax sanction and crossover sanction bills. At the closeof his administration, intergovernmental relations were morecoercive than they had been in 1980. 相似文献

Few researchers have studied trajectories of stress over time in relation to psychosocial outcomes and behaviors among adolescents. A sample of African American adolescents were assessed longitudinally on perceived stress, psychological well-being, support, antisocial behaviors, and academic success. Patterns of stress over 4 time points were developed using a cluster-analytic approach. Differences among the trajectory clusters were examined using psychosocial outcomes and behaviors. Adolescents with chronic levels of stress reported more anxiety and depression, engaged in antisocial behaviors, and reported less active coping than youth in other trajectories. Adolescents with low levels of stress over time reported fewer psychological problems, perceived more social support, and were more likely to graduate from high school than those with higher stress levels over time. We also found that an increase in stress coincided with a lack of support and more psychological problems over time. 相似文献

Previous research on the association between violence and biological stress regulation has been largely cross-sectional, and has also focused on childhood. Using longitudinal data from a low-income, high-risk, predominantly African-American sample (n = 266; 57 % female), we tested hypotheses about the influence of cumulative exposure to violence during adolescence and early adulthood on cortisol responses in early adulthood. We found that cumulative exposure to violence predicted an attenuated cortisol response. Further, we tested whether sex, mothers’ support, or fathers’ support moderated the effect of exposure to violence on cortisol responses. We found that the effect of cumulative exposure to violence on cortisol was modified by sex; specifically, males exposed to violence exhibited a more attenuated response pattern. In addition, the effect of cumulative exposure to violence on cortisol was moderated by the presence of fathers’ support during adolescence. The findings contribute to a better understanding of how cumulative exposure to violence influences biological outcomes, emphasizing the need to understand sex and parental support as moderators of risk. 相似文献

Psychological distress has been inconsistently associated with sexual risk behavior in youth, suggesting additional factors,
such as substance use, may explain this relationship. The mediating or moderating role of substance use on the relationship
between psychological distress and sexual risk behaviors was prospectively examined over the four high school years in a sample
of urban youth (N = 850; 80% African American; 50% female). Growth curve modeling was used to estimate changes in sexual risk
across adolescence and to test its association to psychological distress symptoms and frequency of substance use. Substance
use was associated with psychological distress. Greater psychological distress was associated with increased sexual intercourse
frequency, decreased condom use, and increased number of partners. Substance use fully mediated the relationship between psychological
distress and intercourse frequency and condom use, and partially mediated the relationship between psychological distress
and number of partners. We found no differences in mediation by sex or race/ethnicity and no evidence to support moderation
of psychological distress and substance use on sexual risk. Findings suggest that psychological distress is associated with
sexual risk because youth with greater psychological distress are also more likely to use substances. Practical implications
for adolescent HIV/STI prevention are discussed. 相似文献

President Bush approved 64 preemption acts during 20012005.Fifteen acts were responses to the September 11, 2001, terroristattacks, and five acts extended sunset provisions. The otheracts removed specified powers from states in the fields of banking,commerce, energy, environmental protection, finance, foreigncommerce, health, intellectual property, safety, taxation, telecommunications,and transportation. Only the two Internet taxation prohibitionacts have a major impact on state governments by depriving themof billions of dollars in tax revenues that could be used toexercise their reserved powers. The other acts are minor oneson the periphery of state exercised powers compared to lawsenacted in the period 19641999. 相似文献

In order to assess the nature of threat assessment activity pertaining to members of Congress, 4387 cases involving threatening and other problematic contact were analyzed. The cases were studied regarding subject characteristics, articulated motives, as well as several aspects of contact behavior in relation to approach behavior. Approachers were significantly less likely to have articulated threat language prior to or during their contacts and were also less likely to have stated a policy grievance (foreign or domestic) as the source of their concern. Further, approachers were substantially more likely to have expressed help seeking requests as part of their prior and approach-related contacts and were less likely to have had racial or sexualized content within their contacts. Approachers were also significantly more likely to have had a criminal record as well as displayed symptoms suggestive of major mental illness. Subjects engaging in approach behavior were also less likely to have used an alias, were less likely to be a direct constituent of the target and were more likely to have contacted multiple congressional targets. The implications for threat assessment activity are discussed. 相似文献
