The press is essential for creating an informed citizenry, but its existence depends on attracting and maintaining an audience. It is unclear whether supply-side effects—including those dictated by the owners of the media—influence how the media cover politics, yet this question is essential given their abilities to set the agenda and frame issues that are covered. We examine how ownership influences media behavior by investigating the impact of Rupert Murdoch’s purchase of the Wall Street Journal (WSJ) in August 2007. We collect data on every front-page story and editorial for 27 months, and we compare the difference in political coverage between the New York Times (NYT) and WSJ using a difference-in-differences design. We show that the amount of political content in the opinion pages of the two papers were unchanged by the sale, but the WSJ’s front-page coverage of politics increased markedly relative to the NYT. Similar patterns emerge when comparing the WSJ’s content to USA Today and the Washington Post. Our finding highlights potential limits to journalists’ ability to fulfill their supposed watchdog role in democracies without interference from owners in the boardroom. 相似文献

College campuses have taken on increased responsibility for mobilizing young voters. Despite the discipline’s commitment to civic engagement, political science departments play a minimal role in this programming. This article outlines a course structure—including learning objectives, course outline, and assessments—that treats a campus-wide voter mobilization drive as the basis of an applied political science course. Transforming a campus voter mobilization program into a political science practicum offers advanced skill-building for students seeking political careers and links learning objectives to real world activities. Participants report gains in both knowledge of campaigns and grassroots campaign skills. We argue this type of course particularly benefits students attending colleges and universities in geographic areas that receive little attention from political campaigns as well as those students for whom the traditional route of gaining political experience—an unpaid, off-campus internship—is impractical or even impossible. 相似文献

Depression is a common and debilitating disorder in adolescence. Sleep disturbances and depression often co-occur with sleep disturbances frequently preceding depression. The current study investigated whether catastrophic worry, a potential cognitive vulnerability, mediates the relationship between adolescent sleep disturbances and depressive symptoms, as well as whether there are gender differences in this relationship. High school students, ages 16–18, n = 1,760, 49 % girls, completed annual health surveys including reports of sleep disturbance, catastrophic worry, and depressive symptoms. Sleep disturbances predicted depressive symptoms 1-year later. Catastrophic worry partially mediated the relationship. Girls reported more sleep disturbances, depressive symptoms, and catastrophic worry relative to boys. The results, however, were similar regardless of gender. Sleep disturbances and catastrophic worry may provide school nurses, psychologists, teachers, and parents with non-gender specific early indicators of risk for depression. Several potentially important practical implications, including suggestions for intervention and prevention programs, are highlighted. 相似文献

Roy Allison 《Central Asian Survey》2008,27(2):185-202
The failures of regionalism and regional structures for cooperation between the five CIS Central Asian states are well studied. However, explanations so far do not convincingly account for the apparent enthusiasm of these states for the macro-regional frameworks of the Eurasian Economic Community, the Collective Security Treaty Organization and the Shanghai Cooperation Organization. This article argues that, as with previous efforts at Central Asian regional self-organization, these broader organizations still largely represent a form of ‘virtual regionalism’. But for the Central Asian states they offer a new and increasingly important function, that of ‘protective integration’. This takes the form of collective political solidarity or ‘bandwagoning’ with Russia (and China in the SCO) against processes and pressures that are perceived as challenging incumbent leaders and their political entourage. A primary motivation for Central Asian leaders' engagement in the EAEC, CSTO and SCO, therefore, is the reinforcement of domestic regime security and the resistance of ‘external’ agendas of good governance or democracy promotion. These goals are concealed behind a discourse that denigrates the imposition of external ‘values’ and continues to give pride of place to national sovereignty. This offers little to overcome the underlying fractures between states in Central Asia. 相似文献

Evaluation of laser desorption mass spectrometry and UV accelerated aging of dyes on paper as tools for the evaluation of a questioned document 总被引:1,自引:0,他引:1
Laser desorption mass spectrometry (LDMS) may be used for the detection and identification of dyes found in inks. Naturally-aged and artificially-aged blue and black ballpoint pen inks containing the cationic dye methyl violet were analyzed on paper. The average molecular weight of the dye sample was calculated from LD mass spectral data and plotted versus time. The resulting aging curves demonstrate that, as dye degradation increases, the average molecular weight of the dye decreases. Typical variables involved in ink aging, such as the type of paper and ink formulation, were investigated. Results show that these variables influence the rate of dye degradation. Furthermore, UV accelerated aging has been developed and tested as an alternative to thermal approaches. 相似文献
