South European countries were severely hit by the eurozone crisis. Adopting the theoretical framework of prospect theory, this article conducts an empirical analysis of the interpretation of the situation by the South European political leaders in terms of gains and losses. After discussing the stances of South European countries vis-à-vis a number of contested issues which emerged during the 2010–2013 negotiations, the article goes on to provide a comparative account of the determinants of national preference formation with respect to the eurozone crisis reforms in Cyprus, Greece, Italy, Malta, Portugal and Spain, paying special attention to the relationship between governments and parliaments.  相似文献

Current challenges in medical practice, research, and administration demand physicians who are familiar with bioethics, health law, and health economics. Curriculum directors at American Association of Medical Colleges-affiliated medical schools were sent confidential surveys requesting the number of required hours of the above subjects and the years in which they were taught, as well as instructor names. The number of relevant publications since 1990 for each named instructor was assessed by a PubMed search. In sum, teaching in all three subjects combined comprises less than two percent of the total hours in the American medical curriculum, and most instructors have not recently published articles in the fields they teach. This suggests that medical schools should reevaluate their curricula and instructors in bioethics, health law, and health economics.  相似文献

We present a unique case of death due to the assault and bites of a donkey on a 65-year-old man. The farmer, found dead in his farmyard, had a very deep wound in the anterior region of the neck, with a sharp transection of the trachea and severe bleeding by several minor vessels wall disruptions. The cause of death was established to be massive bleeding combined with asphyxia due to aspiration of the blood. Moreover, multiple contusions with associated skin abrasions and perforations were present. The general impression of the injuries was consistent with an animal's bite marks. Herbivorous or omnivorous bite attacks on humans are rare; instead, these animals attack by kicking, trampling, and kneeling, resulting in secondary blunt injuries. The donkey is usually a docile animal, but its behavior can be aggressive during the mating season, and the possibility of biting should not be underestimated, as illustrated by the 2 cases published previously as well as by the case presented here.  相似文献

The Copenhagen Summit did not conclude the 2 years negotiation process initiated in Bali in 2007. Ten official meetings among parties were not sufficient to reach a conclusion on the future of the international climate change regime after 2012. This paper summarizes the main issues addressed by the parties under the United Nations Framework Convention on Climate Change (UNFCCC) and the Kyoto Protocol tracks in the course of 2009, the longest year ever for climate change negotiations, and tries to explain the reasons behind the Summit's failures. Furthermore, an overview of the main points of the Copenhagen Accord is provided together with its implications and relation with the UNFCCC process.  相似文献

Self‐embedding behavior (SEB) is the repeated insertion of sharp objects, such as needles or pins, into the soft tissues of abdomen, limbs, and other body parts. In this study, two cases of SEB were reported and the scientific worldwide literature reviewed. Thirty‐two cases of SEB were identified through systematic searches in the main bibliographic databases. Mean age was 35 years (SD = 8.97). Just over two‐thirds of the patients were female. Although the number of embedded objects could be as high as 200, major clinical and surgical complications were uncommon and mortality was null. Patients with SEB presented three major diagnoses: psychotic (25%), personality (21.9%), and factitious (28.1%) disorders. The practice of SEB largely went undetected as the patients themselves did not bring it to the attention of family members or physicians and usually denied they have engaged in SEB. A high level of suspicion is required to avoid a missed diagnosis.  相似文献

The illegal use of formalin (commercial formaldehyde) in cosmetic products harms the health of individuals exposed to this substance. Over the last years, the commercial availability of these products, especially those containing irregular dosage of formaldehyde, has increased in Brazil. This work analyzes some products for hair treatment available in the Brazilian market and verifies their safety. The adopted analytical methodology involved sample derivatization with 2,4‐dinitrophenylhydrazine, followed by high‐performance liquid chromatography with ultraviolet detection (UV–VIS) at λ = 365 nm. The limit of quantification is 2.5 × 10?3% w/w, and the recovery tests were around 93%. Some of the samples contained high and illegal formaldehyde levels ranging from 9% to 19% (w/w) and others presented suitable concentrations of the analyte. On the basis of the results, this work discusses the efficiency and practicality of this analytical method for forensic purposes.  相似文献

This article aims to contribute to the field of arts management by identifying the need to make cultural production/management an established field of professional practice and training in Brazil, and the challenges of doing so. To accomplish this, we reviewed several publications and we present first a discourse on theoretical texts in relation to the idea of culture and systems of cultural production and then an analysis of arts management publications in Brazil with observations about this field of work. In this article, we address the current paucity of training opportunities of this kind, the extent to which these roles have yet to be professionalized, and indicate, in the conclusion, that this is a matter of increasing importance and concern for cultural policy in Brazil.  相似文献
