Scholars rely heavily on formal rules to classify legislatures, but parchment institutions may only tell part of the story about how the chamber works. Behind-the-scenes behaviour may counter-balance or temper the power distribution created by formal rules. To begin examining if formal rules are an accurate predictor of actual behaviour, we analyse standing committees in Costa Rica's Legislative Assembly. We find that despite the formal institutions that favour a majoritarian bonus, the opposition party is a full participant in the legislative process in committee sessions. Opposition deputies participate equally or more so than majority party deputies, and deputies of all parties work together to investigate bills and kill legislation evaluated to be flawed, which indicates that formal rules are only one component to understanding legislative behaviour. 相似文献

The hen harrier (Circus cyaneus) is a bird of prey that is persecuted in the United Kingdom, and there is a need for a DNA‐based individual identification and sexing system for the use in forensic investigations. This study reports a new set of PCR primers for the chromo‐helicase‐DNA‐binding protein 1 gene, which allows sexing using PCR‐RFLP. Instead of exonic primers that amplify across a large intron, this set consists of a primer within the intron, enabling reduction in amplicon sizes from 356 to 212 bp and 565 to 219 bp in W and Z chromosomes. DNA degradation and dilution experiments demonstrate that this set is significantly more robust than one that amplifies across the intron, and sequencing of the intronic primer‐binding region across several individuals shows that it is highly conserved. While our objective is to incorporate this primer set into an STR‐based individualization kit, it may in the meantime prove useful in forensic or conservation studies. 相似文献

All cases presenting to the New South Wales Department of Forensic Medicine between January 1, 2001 and December 31, 2010 in which citalopram was detected were retrieved. A total of 348 cases were identified. Citalopram contributed to death in 21.0%, and was incidental in 79.0%. Cases in which citalopram was contributory to death had significantly higher blood citalopram concentrations than incidental cases (0.50 mg/L vs. 0.30 mg/L). Citalopram concentrations varied significantly by contributory status: sole citalopram toxicity (median = 1.30 mg/L), citalopram/other drug toxicity (0.50 mg/L), and incidental cases (0.30 mg/L). Citalopram concentrations also varied by suicide status, with the highest concentration found in suicides where citalopram contributed to death (0.70 mg/L) compared with 0.50 mg/L for nonsuicide cases where citalopram contributed to death. In almost all contributory cases (69/73), other psychoactive substances were also detected, most commonly benzodiazepines (47.9%), alcohol (45.2%), and opioids (40.1%). 相似文献

This paper explores the relation between the fair trade market in the North and producer cooperatives in the South. It specifically focuses on three agricultural cooperatives in Ethiopia, Tanzania, and South Africa to look at the way in which the fair trade market and the state have promoted or hindered alternative production in the global South. Fair trade has gained considerable popularity among Northern consumers in the last decade. For many consumers, the assumption is that buying fair trade ensures producers in the South receive a fair price for their goods. However, fair trade is much more complex than consumer choices or simply offering fair prices to producers. Does fair trade constitute an alternative trading system or is it an attempt to introduce fairer conditions within the current system? What is the role of the state? What is the role of the market? Are there other ways to ensure producers in the global South receive fair prices? These are the central questions explored in this paper. 相似文献

Civic education has been considered a way in which the behaviours and attitudes associated with democratic citizenship can be fostered among the members of a society. Since the emerging democracies are hard-pressed to develop a political culture supportive of democratic rule, civic education has been identified as one way such a political culture can be constructed. Recent studies, however, point to the limited reach of such programmes in sub-Saharan Africa. Based on survey data, others have failed to find even a relationship between formal education and democratic attitudes in parts of Africa. On the other hand, despite the prominence nonformal education has gained in many developing countries, such as those in Africa, the effect of nonformal education on political attitudes has not been subject to empirical testing. Using data from a survey involving a probability sample of 1,484 Senegalese citizens, this article examines the effects of education, both formal and nonformal, on political attitudes among rural Senegalese. Both nonformal and formal education are found to increase the likelihood that people will embrace democratic, tolerant attitudes in Senegal. 相似文献

Anabolic‐androgenic steroids (AASs) are frequently misused. To determine causes of death, characteristics, toxicology, and pathology of AAS positive cases, all cases (n = 24) presenting to the New South Wales Department of Forensic Medicine (1995–2012) were retrieved. All were male, and the mean age was 31.7 years. Deaths were mainly due to accidental drug toxicity (62.5%), then suicide (16.7%) and homicide (12.5%). Abnormal testosterone/epitestosterone ratios were reported in 62.5%, followed by metabolites of nandrolone (58.3%), stanozolol (33.3%), and methandienone (20.8%). In 23 of 24 cases, substances other than steroids were detected, most commonly psychostimulants (66.7%). In nearly half, testicular atrophy was noted, as was testicular fibrosis and arrested spermatogenesis. Left ventricular hypertrophy was noted in 30.4%, and moderate to severe narrowing of the coronary arteries in 26.1%. To summarize, the typical case was a male polydrug user aged in their thirties, with death due to drug toxicity. Extensive cardiovascular disease was particularly notable. 相似文献
