In the following paper, I analyze the influence of advisers and domestic political factors on President Clinton's decision to use force against Slobodan Milosevic and the Serbs in Kosovo in March 1999. I present an analysis and examination of President Clinton's decision-making process, using press reports, personal speeches, etc. In other words, I attempt to trace the process by which Clinton came to the decision to use force in Yugoslavia. Specifically, using the poliheuristic theory, I argue that President Clinton's decision was influenced by noncompensatory domestic political calculations and the strong influence of his Secretary of State, Madeleine K. Albright. Examining how advisers interact with one another, their status in the advisory group, and the manner in which presidents solicit information from advisers will further our understanding of how, when, and under what conditions national security-level decision makers make decisions.  相似文献

The social development model (SDM) is a theory of behavior that has proven useful in explaining the etiology of delinquency, violence, and substance use among adolescents as well as early antisocial behavior among pre-adolescents. A further test of the model is its generalizability across population groups. A section of the SDM representing prosocial influences in the etiology of problem behavior was compared for boys and girls and for children from low- and non low-income families using three waves of child, parent and teacher survey data on a sample of 851 elementary school students. Multiple group structural equation modeling was used to assess differences across groups in both measurement of model constructs and hypothesized structural paths between constructs. The results indicate overall similarity in the reliability of measurement models and validity of structural models.  相似文献

The purpose of this investigation was to identify inmate personal and demographic data that may be used to further define or profile persons with a greater likelihood of being at risk for serving a jail sentence. This study was explorative. The survey administration was similar in format to that conducted by the U.S. Department of Justice. Chaplains were used as survey proctors. Pilot studies were conducted to determine the suitability of survey content. Surveys consisted of 172 items. Subjects included four hundred inmates: males comprised 88.75 percent of the sample, Caucasians 58.25 percent, Blacks 37 percent, Hispanics 3.25 percent and other 1.5 percent of the sample. Respondents ranged in age from 15 to 64 years with an average age of 30.3 years. Less than two percent of the contacted inmates refused participation in the survey. Results are presented for demographic data, select legal/criminal data, select drug and alcohol use data, employment data, health, parent/family data, education data, social data, and “other”.  相似文献
