The American policy landscape during the George W. Bush administration was shaped by a series of traumatic events that confronted the nation and people of the United States. These included the terrorist attacks of 9/11 in 2001, the anthrax attacks in the fall of 2001, military actions in Afghanistan and Iraq, Hurricane Katrina in 2005, the threat of a flu pandemic in 2005 and 2006, the 2007 Intergovernmental Panel on Climate Change reports, and the financial collapse of 2008. The results of the 2008 presidential election appear to be a rejection of the Bush administration's major policy responses to these events, but the variation in type and level of public support among different groups suggests a much more varied and dynamic portrait of America in turbulent times. Using a multiyear panel survey, an interdisciplinary team of political scientists and psychologists analyzed the behavior and political responses to the events by the American public. The findings suggest that even seven years after the events of 11 September 2001, people with higher levels of post-traumatic stress symptomatology related to 9/11 have significantly different interpretations of the threat of terrorism and the appropriate policy responses to it than do others. Perceptions of threat, the political salience of terrorism and other traumatic events, the level of support for political leaders and assessments of the government's actions vary over time and across different groups within society based on the psychological, political and social, and personal characteristics of the respondent. These results help to open the black box of aggregate public opinion by providing a detailed portrait of how psychological, social, political, and personal factors affected perceptions and political behavior during the George W. Bush administration. 相似文献

The use of probability propositions is widespread in Intelligence estimation and strategic forecasts, as in everyday life. This paper attempts to give clear meaning to the use of probability statements for future strategic assessment. The first half presents possible interpretations in the philosophy of probability, while the second part applies the understandings of the first half to the Intelligence estimation process. A recommendation for a combination of ‘a priori’ interpretation of probability with a higher level of ‘relative frequency’ interpretation is the result of this paper. 相似文献

In much of the debate about the current role of frontier development (settlement, colonization) in many so-called Third World countries, frontiers in the latter are invariably compared negatively with the late nineteenth-century experience of the IIS frontier held up as an example that others should attempt to follow Recent approaches to the history of the IIS frontier however have questioned the Jeffersonian and/or Turnerist ideal of an egalitarian democracy ofsmall farmers who managed to construct an harmonious and viable frontier in the New World. Rather than contributing positive cultural and political attributes and characteristics to American society, as was claimed by many IIS historians during the Cold War era, the IIS frontier involved genocide, demographic collapse, ecological devastation, economic exploitation and dependency, widespread inter-ethnic violence, social polarization, political corruption, disempowerment and ideological intolerance. The IIS frontier experience did not represent an agrarian reform favouring small farmers, nor was it one of equal opportunity: it should not, therefore, be held up as a model for the rest of the world to imitate if at all possible. 相似文献

Situated within a positive psychology perspective, this study explored linkages between adolescent students’ positive subjective
well-being and their levels of engagement in schooling. Specifically, using structural equation modeling techniques, we evaluated
the nature and directionality of longitudinal relationships between life satisfaction and student engagement variables. It
was hypothesized that adolescents’ life satisfaction and student engagement variables would show bidirectional relationships.
To test this hypothesis, 779 students (53% female, 62% Caucasian) in a Southeastern US middle school completed a measure of
global life satisfaction and measures of cognitive, emotional, and behavioral engagement at two time points, 5 months apart.
A statistically significant bidirectional relationship between life satisfaction and cognitive engagement was found; however,
non-significant relationships were found between life satisfaction and emotional and behavioral student engagement. The findings
provide important evidence of the role of early adolescents’ life satisfaction in their engagement in schooling during the
important transition grades between elementary and high school. The findings also help extend the positive psychology perspective
to the relatively neglected context of education. 相似文献
