The causal factors associated with increases in depressive symptoms among adolescent girls remain an area of theoretical debate, and the limited research considering a hormonal influence has provided mixed results. The goal of the present study was to test a set of longitudinal associations, that, if found, would provide support for a hormonal contribution to these changes. Specifically, this study tested the hypotheses that changes in depressive symptoms among adolescent girls would be associated with phase-specific symptoms of the menstrual cycle during early adulthood; that these associations would differ across three phases of the menstrual cycle; and that the pattern of associations would differ for changes in depressive symptoms during early- and late-adolescence. The sample consisted of 47 women with longitudinal data from 12 to 21 years old (approximately 91% European Canadian, 4% Middle Eastern Canadian, 2% Haitian Canadian, and 2% Asian Canadian). Consistent with expectations, results showed that early-adolescent increases in depressive symptoms were negatively associated with menstrual-phase negative affect, and positively associated with mid-cycle negative affect, but not associated with premenstrual negative affect; whereas late-adolescent change in depressive symptoms was only associated with depressive symptoms at 20-21 years. Thus, early-adolescent changes in depressive symptoms are longitudinally associated with later mood change across the menstrual cycle, suggesting a common underlying cause, which is hypothesized to be hormonal. Moreover, results suggest that, with respect to variables that are involved in affective development, important differences exist between early- and late-adolescence. The discussion considers menstrual-cycle-related symptoms (e.g., dysmenorrhea) during adolescence, and the need to study their effects on development. It is suggested that focused intervention and prevention efforts may be indicated to interrupt negative developmental outcomes. 相似文献

In this introduction, we review the literature on intellectual property rights and access to medicines, identifying two distinct generations of research. The first generation analyzes the origins of new intellectual property rules, in particular the World Trade Organization’s Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS), and the significance of TRIPS to developing countries. The second generation examines national-level experiences, as countries adjust their laws and practices to conform to TRIPS. Based on the insights provided by the articles in the special issue, we contribute to the second generation by considering a pair of overarching sets of issues. First, we highlight the domestic political challenges that affect how countries go about implementing their new obligations under TRIPS. We argue that alliances and coalitions are necessary to underpin the use of policy instruments designed to conform to TRIPS while taking into account local conditions and needs, and we present insights that allow us to understand why alliances and coalitions are difficult to construct and sustain in this area. Second, we explain why policies that many countries adopt in response to TRIPS often do not generate their desired or intended outcomes. In the last section of the introduction, we review the articles that appear in this special issue. 相似文献

This article assesses the successes and setbacks of Moscow’s policy of counterinsurgency and beyond. It challenges the general consensus in scholarship positing that military successes associated with Chechenisation have been obtained against the backdrop of Chechnya’s increasingly autonomous status within Russia, considered by some as a case of ‘systemic separatism’. The article tracks how four key mechanisms (Chechnya’s institutional design, internal opposition to the Kadyrov clan, the tradition of blood feud among kadyrovtsy—initially Chechen paramilitary forces named after both Kadyrovs, gradually transformed into seemingly regular Ministry of Interior (MVD) units—and Chechnya’s economic dependency on Moscow) have enabled Moscow to maintain control over Chechnya while simultaneously allowing its elites to consolidate power within the republic. 相似文献

Voters’ Knowledge of Their Representatives: The Direct and Conditioned Effects of Parliamentary Work
This article examines factors that influence voters’ knowledge of their representatives, a key element in securing the responsiveness and accountability of parliamentarians. We argue that the parliamentary work of MPs (Members of Parliament) benefits incumbents through increased name recall, and that this relationship is conditional on: the incumbents’ candidacy; the voters’ political competence; and their ideological proximity with their representatives. Combining data on French MPs’ activities with a 2007 CSES post‐election survey enables us to test our hypotheses, while controlling for confounding factors. The empirical analysis demonstrates that some parliamentary activities increase the voters’ capacity to recall the name of their MPs. The latter are therefore incentivised to be responsive to and serve their constituents. However, we also find that voters’ political competence and ideological proximity with their MP alter the relationship between parliamentary work and name recall. This may potentially introduce some biases in the democratic process of accountability. 相似文献

Previous research has shown that those who won an election are more satisfied with the way democracy works than those who lost. What is not clear, however, is whether it is the fact of winning (losing), per se, that generates (dis)satisfaction with democracy. The current study explores this winner/loser gap with the use of the 1997 Canadian federal election panel study. It makes a theoretical and methodological contribution to our understanding of the factors that foster satisfaction with democracy. At the theoretical level, we argue that voters gain different utility from winning at the constituency and national levels in a parliamentary system, and that their expectations about whether they will win or lose affect their degree of satisfaction with democracy. On the methodological front, our analysis includes a control group (non-voters) and incorporates a control for the level of satisfaction prior to the election. The results indicate that the effect of winning and losing on voters' satisfaction with democracy is significant even when controlling for ex ante satisfaction before the election takes place, and that the outcome of the election in the local constituency matters as much as the outcome of the national election. They fail to show, however, that expectations about the outcome of the election play a significant role in shaping satisfaction with democracy. 相似文献

A key to the success of public organizations is their ability to identify and build capacity, particularly their distinctive competencies, in order to produce the greatest value for key stakeholders. This article grounds this proposition in the resource-based view of organizations and presents a method for identifying and making use of distinctive competencies in the form of a "livelihood scheme"—a business model appropriate for the public sector—that links distinctive competencies to organizational aspirations and goals. The case of a major public sector training and consultancy unit that is part of the United Kingdom's National Health Service is used as illustration. A number of conclusions are offered in the form of a set of propositions tied to the resource-based view and related research issues. The results contribute to both public strategic management theory and practice. 相似文献

The U.S. Supreme Court held in Wilson v. Arkansas (1994) that the common law “knock-and-announce” principle formed part of the “reasonableness” inquiry under the Fourth Amendment. However, the Court’s opinion gave little guidance as to what would be unreasonable under these circumstances. Some critics expressed concern that this lack of guidance would lead to many variations among lower courts. Other observers discerned a signal that little should be deemed “unreasonable” in the context of “knock and announce.” These criticisms are analyzed through a review of lower court interpretations of Wilson. 相似文献

Employees rate the fairness of organizational policies by applying principles of distributive and procedural justice. Using
Leventhal’s (1980) Principles of Procedural Justice, the current study surveyed 279 upper-level college and graduate students
to determine the impact each principle has on support for drugtesting policies. The results support the hypothesis that drug-testing
programs that violate these principles are viewed as unfair. 相似文献
