Traditionally, the virtue of democratic elections has been seen in their role as means of screening and sanctioning shirking public officials. This article proposes a novel rationale for elections and political campaigns considering that candidates incur psychological costs of lying, in particular from breaking campaign promises. These nonpecuniary costs imply that campaigns influence subsequent behavior, even in the absence of reputational or image concerns. Our lab experiments reveal that promises are more than cheap talk. They influence the behavior of both voters and their representatives. We observe that the electorate is better off when their leaders are elected democratically rather than being appointed exogenously—but only in the presence of electoral campaigns. In addition, we find that representatives are more likely to serve the public interest when their approval rates are high. Altogether, our results suggest that elections and campaigns confer important benefits beyond their screening and sanctioning functions. 相似文献

A 58‐year‐old man died suddenly in Madagascar and poisoning was suspected. The body was embalmed after death and the general state of preservation was good. We found a major aortic dissection with a large false lumen from the aortic root to the common iliac arteries and a hemopericardium with formalinized blood clot. The intimal tear was on the ascending aorta, and an intramural hemorrhage was noted at the right coronary artery, attesting to a retrograde dissection. Microscopic studies confirmed aortic dissection with extensive intramural hemorrhage and also confirmed the retrograde dissection to the right coronary artery with a reduction of 90% of the true lumen. Classically, aortic dissection occurs in individuals with hypertension and individuals with genetic disorders of collagen formation. The diagnosis is often first established at the postmortem examination. Aortic dissection is therefore dealt with largely in necropsy studies. The usual cause of death is rupture into the pericardial sac. One case of bloodless dissection has been reported but the sudden death was explained by acute myocardial ischemia secondary to dissection of the left coronary artery. In our case, we found major hemopericardium and also intramural hemorrhage at the right coronary artery. We were able to make the diagnosis of aortic dissection and exclude the suspicion of homicide 15 days after death and after embalming. 相似文献

The quality and the quantity of information recalled by eyewitnesses during a criminal investigation is of crucial importance. To increase the volume of details recalled during an interview, the cognitive interview recommends using various retrieval strategies to enhance recall. We tested a new retrieval instruction, the open depth (OD) instruction. The efficacy of this new instruction was assessed with the number of unit of information and the accuracy rate. We also assessed the cost-and-benefit of this new instruction with measures of repetition. Students watched a video of a simulated robbery and participated later in face-to-face interviews. In Study 1 (N=60), the cognitive interview using the OD instruction increased recall compared to the interview using the change of perspective (CP) instruction, without affecting the accuracy rate. The redundancy rate was higher with the OD instruction than with the CP instruction. In Study 2 (N=40), the OD instruction generated more new information without affecting the accuracy rate than the interview using motivated recall (MR) instruction. The repeated information to new information ratio was lower with the OD instruction than with the MR instruction. The advantages of the OD instruction for investigative interviewing purposes are discussed. 相似文献

In 1746, Antoine Deparcieux (1703–1768) published Essai sur les probabilités de la durée de la vie humaine [An Essay on the Probabilities of the Duration of Human Life]. Deparcieux analyzed in detail empirical observations. As a mathematician and physicist, he can be considered, after Halley and Struyck, one of the founders of the estimation of longevity and all the issues surrounding that concept. The article analyzes the statistical data Deparcieux presented in his book and examines the way he dealt with them. He criticized the methods of his predecessors and showed what, according to him, were “good” data. Although he only had lists of annuitants or ecclesiastical registers at his disposal and no data from the government or state, Deparcieux constructed his calculations with careful regard to the value and quality of the figures used. He also envisaged a specific project to collect data about infant mortality. His work holds an important place in the history of French demographic statistics. 相似文献

Abstract Thirty‐nine species of cetaceans have been officially recorded in Brazil. Therefore, policies aimed at their conservation and management are highly important. This article examines Brazilian legislation, approved between 1986 and 1998, related to the conservation of cetaceans. On December 21, 1986, the first legislation specifically directed at cetaceans, Regulation N‐011, was approved. However, it only addressed small cetaceans. On December 18, 1987, the legislation was extended through Federal Law No 7643 to all cetacean species. From this date onward, the commercial taking of whales was banned from Brazilian waters. Presendy, Brazil has two Federal Laws, two Federal Decrees, one State Decree and nine Regulations related to cetacean conservation. However, although Brazilian cetacean species are now protected by law, they still face numerous threats. This article also proffers suggestions on how to improve the conservation prospects of cetaceans in Brazilian waters. 相似文献

This article adopts a perspective of climate justice as an object of discourse and takes the bargaining coalitions at the Conference of the Parties as the relevant units to map the heterogeneous discourse on climate justice at the Cancun COP16. Based on the statements of nine coalitions, the analysis identifies three discourses on climate justice. The conflict discourse articulates the North–South duality over issues of historical responsibility for climate change. The transition discourse points to solving the problem of sharing the cost of mitigating climate change through a process of global low-carbon growth. The vulnerability discourse focuses on the urgency of ambitious actions by all parties. These three discourses, and their appropriation by the bargaining coalitions, are inherent of new alignments among developed and developing countries alliances and blocs that simultaneously reproduce and surpass the North–South ideological divide. 相似文献

This article seeks to understand how development aid is translated into city management practice in the global South and the implications of this for the power dynamics between municipal governments and international aid agencies. The study examines La Chureca, the rubbish dump and slum of Managua, Nicaragua, and its regeneration programme, the Barrio Acahualinca Integrated Development Programme. In the article, we explore the formulation and initial implementation of the Programme in terms of the construction of an action net in which, by a chain of translations, the Programme was transformed from an aid programme managed by international aid organisations into the management practice of the city of Managua. Despite the silent infiltration of important issues brought to the municipal political agenda by the development aid programme, small acts of defiance and resistance were also enacted by local actors who twisted the Programme to fit local needs.

This paper uses a simultaneous equations model to analyze increases in intergovernmental fiscal transfers and associated vote changes in Portuguese legislative elections. The results suggest that election year increases in transfers by the central government to municipalities secure added votes, and that these transfers are targeted at jurisdictions where the government faces the risk of losing support. 相似文献

This article analyses the relative impact of position versus performance issues in Portuguese voting behaviour at the 2002 legislative elections and examines the relative importance of issues compared to other determinants of voting behaviour. The article first defines issues and then presents a model of voting choice, before examining the salience of different issues. The impact of issues, as opposed to other major voting determinants, is evaluated as vote predicting factor. 相似文献
