This article advances the idea that coalition formation and maintenance in highly fragmented presidential regimes is not only crucial to overcoming policy deadlock, but in some cases, critical to ensuring government survival. To advance this argument, the article looks at the formation and demise of legislative coalitions in Ecuador between 1979 and 2006. The empirical data suggest that paradoxically, government coalitions became more difficult to sustain after the adoption of institutional reforms intended to strengthen the president's legislative powers. The adoption of those reforms, it is argued, undermined the legislative incentives to cooperate with the government and helped to accelerate coalition erosion. Not only did the reforms fail significantly to avoid policy deadlock, but in some cases they contributed to the early termination of presidential mandates. This article contributes to the study of coalition survival and how it is linked to policymaking. 相似文献

Brazilian diplomats and academics alike have long regarded regional leadership as a springboard to global recognition. Yet Brazil's foreign policy has not translated the country's structural and instrumental resources into effective regional leadership. Brazil's potential followers have not aligned with its main goals, such as a permanent seat on the UN Security Council and Directorship‐General of the World Trade Organization; some have even challenged its regional influence. Nevertheless, Brazil has been recognized as an emergent global power. This article analyzes the growing mismatch between the regional and global performance of Brazilian foreign policy and shows how both theoretical expectations and policy planning were “luckily foiled” by unforeseen developments. It argues that because of regional power rivalries and a relative paucity of resources, Brazil is likely to consolidate itself as a middle global power before gaining acceptance as a leader in its region. 相似文献

A fast and simple LC-MS/MS method was developed for screening mephedrone, butylone, methylenedioxypyrovalerone (MDPV), flephedrone, methylone and methedrone in bulk powder samples. Samples were separated on a reverse phase column using gradient elution with mixtures of water, acetonitrile and formic acid. After optimization a limit of detection of about 2ngmL(-1) was achieved using multiple reaction monitoring (MRM) mode. Total run time was less than 8min. Typical fragmentation characteristics of the studied compounds are discussed. The method was successfully applied to several unknown bulk powder samples seized by the Hungarian Customs and Finance Guard. One of the samples contained the new designer drug 4'-methylethcathinone (4-MEC), which was identified and characterized by LC-MS/MS, NMR, FT-IR and LC-TOF-MS techniques. The method is also deemed to be applicable for the screening of simple dosage forms such as tablets and capsules. 相似文献

Various methods have been published in the literature to estimate endocranial capacity. These are based on mathematical equations using measurements made directly on the skull or indirectly from X-rays, by filling the skull with various materials, by endocasts both physical and virtual (using 3D CT-scan reconstructions). Each method has its advantages, limits and drawbacks. A useful method is one that is simple, time-efficient, cheap, and reproducible. For this study we estimated endocranial capacity by filling the skull with calibrated glass beads. We used a thorough protocol of tamping to ensure results reproducibility. Intra- and inter-observer trials showed no significant differences. The method was applied to 130 recent French (West European) skulls (65 males and 65 females). Sexual dimorphism was studied using logistic regression functions, discriminant analysis, and neural network. The best results were obtained using the neural network, built with two hidden nodes in the hidden layer and one output node, and trained with a steepest descent algorithm. Our tests show that there is obvious sexual dimorphism (p < 10(-5)) of the weight of the skulls (623.44 ± 106.83 g in males; 548.07 ± 94.57 in females), the weight of the glass beads used to fill the skulls (2379.83 ± 228.92 g in males; 2095.95 ± 145.49 in females), and endocranial capacity (1676.47 cm(3) ± 161.26 in males; 1476.48 ± 102.49 in females), but overlapping between sexes is quite significant. The average ECC in male (1676.5 cm(3)) and in female (1476.5 cm(3)) subjects is higher than those previously published, which deserves some discussion. 相似文献

This article provides general and specific insights into Brazil's developing interest group system. In doing so, it presents a theoretical foundation for understanding this group activity, past and present. The general insights of the role of interest groups under limited political participation and authoritarian regimes down to the 1980s plus the period of democracy since then, provide background for the specific insights of the article. The specifics focus on three aspects of Brazil's contemporary interest group activity: (1) utilization of a neo-institutional analytical approach for understanding the interest group environment; (2) an analysis of the types of lobbying activity that takes place in Brazil today, including a case study; and (3) an assessment of the level of development of the group system by placing it in a comparative perspective with both advanced liberal democracies and other Latin American countries. The findings show that Brazil is, indeed, taking on many of the characteristics of a developed interest group system; but its past, its political culture, its political economy, and, paradoxically, its new-found status as an international power, work to present several challenges to its group system and thus to a full democratization of the country.

This paper examines the decision to refer a sexual assault case for prosecution using a sample of 730 reported sexual assaults in which the victim received a medical/forensic examination. The decision to refer a case for prosecution was modeled using an algorithmic modeling technique, Random Forests. The key advantages of this modeling approach include its superiority in predicting case outcomes and its ability to easily uncover nonlinear relationships. Key results indicate that the likelihood of referral increased when sperm was found and documented, when the victim could identify the suspect, and as the severity of nongenital injury increased. Neither the presence nor the severity of genital injury impacted the decision to refer a case for prosecution. On the whole, suspect and report characteristics had the largest impact on referring cases for prosecution, with victim characteristics having little influence. 相似文献
