Strengthening the state is central to the post-communist reform agenda. Here, state capacity combines organisational, material and social resources and is conceptualised along four dimensions: ideational, political, technical and implementational. This conceptualisation is applied to a comparative, survey-based analysis in 2002 of 125 medium-ranking officials in two post- communist Central Asian countries, Kazakhstan and Kyrgyzstan. The findings reveal that although Kazakhstan's controlled economic reform programme and natural resources have placed it in a stronger position to develop its state capacity, important ideational, political and implementational problems pose long-term obstacles for reform. In turn, Kyrgyzstan's early liberalisation in the absence of economic and social resources may be serving to undermine its state capacity.  相似文献

In April 1994 GASB released Concepts Statement No. 2, Service Efforts and Accomplishments Reporting , bringing required SEA external financial reporting a very large step closer to reality. Before long, public financial officials may be required to annually report measures of performance. We are now about halfway through the experimentation phase established in Statement 2. This article summarizes the status of GASB's SEA experimentation process. It then suggests important behavioral, auditing, and other issues which GASB ought to address before proceeding with any formal pronouncements regarding SEA reporting requirements.  相似文献

Whether one votes and how one votes   总被引:1,自引:0,他引:1

The aim of this paper is to determine if whether one votes effects the vote that is cast. Using an economic model of voting and observed voting results on nuclear power referenda, the answer is a resounding yes. Overcoming registration, turnout, and “roll off” hurdles dramatically increases the odds of voting against nuclear power. Indeed, participation swamps both economic and preference variables in the explanation of nuclear power voting outcomes. The lesson is that there is a structure to participation at the polls that should not be ignored by those interested in analyzing voting outcomes.  相似文献

Empirical studies measuring the impact of globalization on social spending have appeared recently in leading journals. This study seeks to improve upon previous work by (1) employing a more sophisticated and comprehensive measure of financial openness; (2) using a more accurate measure of trade openness based on purchasing power parities; and (3) relying on social spending data that are more complete than those used by previous studies on Latin America. Our estimates suggest that several empirical patterns reported in previous work deserve a second look. We find that trade openness has a positive association with education and social security expenditures, that financial openness does not constrain government outlays for social programs, and that democracy has a strong positive association with social spending, particularly on items that bolster human capital formation.  相似文献

Despite the vast coalition literature, pre-electoral coalitions have never been at the center of any systematic, cross-national research. Given their prevalence and potential impact on government composition and policies, this represents a serious omission in our knowledge of coalitions. I begin to remedy this situation by testing two hypotheses found in the literature on party coalitions. The first is that pre-electoral coalitions are more likely to form in disproportional systems if there are a sufficiently large number of parties. The second is that pre-electoral coalitions are more likely to form if voters face high uncertainty about the identity of future governments. These hypotheses are tested using a new dataset comprising legislative elections in 22 advanced industrialized countries between 1946 and 1998. The results of the statistical analysis support the first hypothesis, but not the second.  相似文献

A cross-sectional non-clinical sample of 1,218 adolescents, aged 10–17 years, completed measures of stress, rumination, and depression to allow tests of the response style theory of S. Nolen-Hoeksema [J Res Adolesc 4:519–534, 1994] in adolescents, in particular whether increasing levels of stress and rumination in early adolescence are predictive of the onset of the gender difference in depression. Overall, females reported higher levels of stress, rumination, and depression than males. The onset of the gender differences in stress and depression occurred at age 13 years, and for rumination one year earlier at 12 years. Significantly, also from 13 years, rumination explained the gender difference in depression by showing that it significantly mediated the effect of gender on depression. Gender moderated the rumination to depression relationship; specifically the association was stronger for females than males. Developmental differences were noted in that rumination significantly mediated between stress and depression earlier in the age range for females than males. Results supported many of the predictions of Nolen-Hoeksema’s model of the emergence of a gender difference in adolescent depression.

This article compares Moscow’s and Washington’s foreign policies toward the Middle East in 1982 and 2008. In 1982, Moscow and Washington each had a distinct set of friends and foes. In 2008, Washington still has a distinct set of friends and foes, but Moscow has relatively good relations with all governments and most major opposition movements in the region—the only exceptions being Al Qaeda and its affiliates. It is argued that Putin’s policy toward the Middle East is not really aimed at displacing the U.S. in the region, but protecting Russia and Russian interests from Al Qaeda and its allies. Indeed, a continued American presence in the region serves to protect Russian interests in the region.

Fluoxetine is a selective serotonin reuptake inhibitor, commonly used for the treatment of a variety of psychopathological conditions. As such, fluoxetine may be expected to appear in clinical and forensic cases. Dermestes maculatus De Geer (Coleoptera: Dermestidae) has been recognized as a relevant component of the insect fauna associated with decomposing human and animal remains. Experiments were conducted to study the effect of fluoxetine on developing D. maculatus using two‐drug administration models: a non‐living animal model (pork muscle) and a living one (Sus scrofa L. pigs). We assessed the duration of immature stages and total life cycle, as well as morphological parameters (body length, cephalic width, and weight). The effect of fluoxetine was studied at an overdose concentration: In the non‐living animal model the drug was mixed with macerated pork muscle (2000 mg/kg) and in the living animal model, pigs were given the drug orally (833 mg/kg). A control was used for each model. Daily observations were performed from the beginning to the end of the experiments. GC‐MS was used for drug detection and quantification. There were no statistically significant differences in the duration of immature stages, life cycle, larval mortality, morphological parameters, or sex ratio, between treatment and control, regardless of the drug administration model. Given that fluoxetine had no detectable effect on the development of D. maculatus, detection of this drug in forensic situations would not compromise the accuracy of PMI estimations.  相似文献
