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

Despite United Russia’s (Edinaya Rossiya—UR) dominance in repeated Russian legislative elections, the correlates of the party’s electoral support remain noticeably understudied beyond the influence of electoral manipulation. I pinpoint the specific contours of UR’s strongholds in the two most recent parliamentary elections in Russia—2007 and 2011—focusing on raion- and regional-level correlates of the vote using an original dataset. UR has been undergirded by geographically concentrated ethnic minorities and the countryside, and these patterns of support have persisted even in the absence of fraud, suggesting that the dominant party’s electoral windfalls cannot be attributed solely to electoral malfeasance. 相似文献

Current explanations of effective voter mobilization strategies maintain that turnout increases only when a potential voter is persuaded to participate through increased social connectedness. The connectedness explanation does not take into account, however, that registered voters, by registering, have already signaled their interest in voting. The theory presented in this article predicts that impersonal, noticeable messages can succeed in increasing the likelihood that a registered voter will turn out by reminding the recipient that Election Day is approaching. Text messaging is examined as an example of an impersonal, noticeable communication to potential voters. A nationwide field experiment (n = 8,053) in the 2006 election finds that text message reminders produce a statistically significant 3.0 percentage point increase in the likelihood of voting. While increasing social connectedness has been shown to positively affect voter turnout, the results of this study, in combination with empirical evidence from prior studies, suggest that connectedness is not a necessary condition for a successful mobilization campaign. For certain voters, a noticeable reminder is sufficient to drive them to the polls. 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

Over the last several decades, numerous civil wars have ended as a consequence of negotiated settlements. Following many of
these settlements, rebel groups have made the transition to political party and competed in democratic elections. In this
paper, I assess the legacy of civil war on the performance of rebel groups as political parties. I argue that the ability
of rebels to capture and control territory and their use of violence against the civilian population are two key factors explaining
the performance of rebels as political parties. I test these hypotheses against the case of the Farabundo Martí National Liberation
Front (FMLN) in El Salvador using one-way ANOVA and multivariate regression analyses. In analyzing the FMLN’s performance
in the 1994 “elections of the century,” I find that, as a political party, the FMLN benefited both from the state’s violently
disproportionate response and its ability to hold territory during the war. 相似文献

This study examines situation versus personality effects on foreign policy decision making. It proposes that while both factors are important in explaining decision outcomes, the relative importance of each in a given circumstance is a function of the structural constraints imposed by the policy decision environment. Following Maoz (1990) and Maoz and Astorino (1992b), a decision-game theoretic framework is used to "reconstruct" policy decision problems in order to study individual and environment effects concurrently. The substantive focus is the ten decisions that comprised the major events of the 1970 Civil War in Jordan. The decision reconstructions are used to rate these decision tasks according to the presence and degree of structural constraint. Although it represents a preliminary test, the decision analysis indicates that in structurally constrained decision settings, policymakers tended to respond in accordance with environmental clues, while response variability and evidence of simplifying decision heuristics was greater in more fluid decision settings. 相似文献
