This paper examines the lessons learned from Kenya's 2007 post election violence and what has happened since then. It notes that the root causes of the violence still persist, have not been addressed, and easily could be reignited. Faced with a situation where institutions and the rule of law have been weakened deliberately and where diffused violence is widespread, both Kenya's transition to democracy and the fate of the nation remain vulnerable. The argument here is that the problems faced in holding and managing elections in conflict situations often are not simply technical. Instead, in Kenya and elsewhere, many difficulties are symptomatic of larger political and institutional questions related to democratic change that are more difficult to analyze in causal terms or to address. 相似文献

In some Latin American nations, policy change occurs frequently, while in others it is stable, less prone to shifts with the prevailing political climate or shocks. The conditions under which institutional rules and the powers of key actors influence the capacity for governance vary, and this variation is seldom addressed in the literature. This project examines the effects of the interactions between key policymakers (the executive and the legislature) in Latin America on policy stability across different institutional frameworks. Countries with simultaneously strong executives and weak legislatures are shown to have unstable policy environments, as are countries with a history of unified government and, to a lesser extent, candidate‐centered electoral systems. 相似文献

Lists of banned classes of doping agents are released by the International Olympic Committee, adopted by other sports authorities and updated regularly, including the substance classes stimulants, narcotics, diuretics, anabolic agents, peptide hormones, beta-blockers etc. There are different classes of restriction: anabolic and masking agents (anabolic steroids, diuretics etc.) are always banned for athletes regardless of their topical activity (training or competition) several substances are permitted with certain restrictions (caffeine below a cut-off value, or inhalation of some beta 2 agonists) beta-blockers are prohibited in competitions of certain sports disciplines the majority of the substances (stimulants, narcotics etc.) is prohibited during competitions, so that they do not have to be analysed in out-of-competition samples. A differentiation between training and competition period is impossible by means of hair analysis due to the uncertainty of (especially short-term) kinetic considerations related to hair growth. Therefore, the analytical identification of doping relevant substances in hair is not always a sufficient criterion for a doping offence and the identification of stimulants, beta-blockers etc. in hair would be entirely irrelevant. The most interesting target substances are certainly the anabolic agents, because their desired action (enhanced muscle strength) lasts longer than the excretion, leading to sophisticated procedures to circumvent positive analytical results in competition control. Besides the analysis of out-of-competition control samples, the long term detection of steroids in hair could provide complementary information. An analytical approach to the identification of exogenous steroids in hair requires consideration of the presence of many other steroids in the hair matrix interfering the analysis at trace levels, and of a limited chemical stability. The analysis of endogenous steroids in hair appears to be even more complicated, because the possibility of many biotransformation reactions from (into) other precursors (metabolites) has to be taken into account. Precursor substances of anabolic steroids (especially esters as application forms) are very promising analytical targets of hair analysis, because they can only be detected after an exogenous intake. The quantitative evaluation of active parent compounds like testosterone (which is actively involved in physiological processes of hair growth) in hair is still controversial. Clinical applications under reproducible conditions can be useful, but the biovariability of these parameters will probably prevent the definition of acceptable cut-off levels as a criterion of abuse. 相似文献

In this paper we use a simple Downsian spatial model to analyze the properties of campaign contributions. We first consider campaign contributions that are intended to inform voters of candidate positions. We show that it is difficult to construct arguments in a Downsian spatial model for why some voters would choose to contribute to a candidateand the candidate would want to spend the money contributed to inform voters of his position. We then define persuasive campaign expenditures as those that are intended to convince an individual to vote for a candidate regardless of the candidate's position on issues. In the presence of persuasive campaign expenditures some voters have an incentive to contribute to one or both candidates, and the candidates have an incentive to spend the money. We show why the nature of persuasive campaign expenditures may explain both their growth in recent years and the increasing advantage of incumbency. 相似文献

A fatal maprotiline intoxication is presented. The postmortem anatomical and toxicologic findings are discussed, as is the mechanism of maprotiline toxicity. This report is, to the best of our knowledge, the sixth fatal maprotiline poisoning in the medical literature. 相似文献

Children with parents with mental health problems have an increased risk of adverse developmental outcomes. Nonetheless, services for these children are still scarce in Switzerland. Therefore, an innovative program was developed, implemented, and evaluated in close practitioner-researcher cooperation. The program aims to support these children by providing lay supporters as so-called “godparents” to them. The program evaluation shows that the continuity of contacts between children and godparents builds the ground for a relationship that fosters the children’s development and relieves their parents. A carefully undertaken process of matching families with godparents appears to be crucial for a lasting godparenthood. However, a main challenge is the acquisition of godparents, who engage on a voluntary basis in the program. 相似文献
