In the light of models of composition ofgovernment expenditure and economic growthand the growing globalization process, weinfer that countries should tend to asimilar structure of government spendingover time. In fact, using Tukey box-plotsand σ-convergence we show evidenceof an approaching process in thecomposition of government expenditures inOECD countries for the period 1970–1997. Wealso identify by means of cluster analysisthat most countries are converging towardstwo different models: one including twelveEuropean and non-European countries and theother composed solely of eight countries ofthe European Union. 相似文献

The Y-chromosome haplotypes defined by nine STRs (DYS19, DYS385, DYS389I, DYS389II, DYS390, DYS391, DYS392 and DYS393) were studied in 207 unrelated individuals from Central Portugal and 63 from Azores Islands. The most common haplotype in Central Portugal was shared by 3.4% of the males, while 160 haplotypes were unique. In Azores Islands the most common haplotype was shared by 6.4% of the males, while 40 haplotypes were unique. The values of haplotype diversity were 0.993 for Central Portugal and 0.976 for Azores Islands. 相似文献

Economists have always criticized politicians' behaviour. Adam Smith called politicians
“crafty and insidious"; and, more recently Brennan and Buchanan have applied Gresham's law to politics, arguing that the man
for whom the expected profit is highest will be the highest bidder for political power. However in their model there is not
an argument to explain why these people are elected to public offices.
This paper presents a supply model and a demand model explaining why politicians behave as
“wicked" men, and are elected by the citizens. Firstly, we develop a model of repetitive and reputation games that shows why
probity is not important for many politicians. The second model employs asymmetric information theory to explain why voters
elect “wicked" people even if probity is a highly estimated value for them. The paper ends with some suggestions of legal
reforms for reducing this asymmetry of information.

We present a case of peritonitis and death due to the misplacement of a laparoscopic adjustable band inserted through, instead of around, the stomach. This represents the first case in the published literature where a LAP-BAND perforated the stomach, followed by peritonitis and death. The morbidly obese female patient with a history of hypertension and arthritis was 47 years old, 5 feet 6 inches tall, weighed 361 pounds, and had a body mass index of 58.3. She underwent a 2-hour, elective, LAP-band insertion operation to achieve weight loss; 27 hours after band insertion, following the conduction of all FDA-mandated Lap-Band postoperative protocol (including a radiologic Gastrogrografin swallow), the patient was discharged with "no evidence of esophageal stasis or obstruction." She remained out of hospital care and in her residence until she called for and was taken by an ambulance to an alternate, local hospital (57 hours after band insertion), when gastric perforation was confirmed via x-ray and CT scans. No open surgery was attempted to repair the damage, and cardiac arrest ensued 7 hours after admission to the second hospital. The patient was pronounced dead 64 hours after LAP-band insertion. This unique case is significant, given that there were no deaths of this kind reported in The LAP-BAND(R) Adjustable Gastric Banding System Summary of Safety and Effectiveness Data by the United States Center for Devices and Radiologic Health, of the Food and Drug Administration, or in searches of the published literature. 相似文献

The present article tests predictions of rational political business cycle models using a large and previously unexplored data set of Portuguese municipalities. This data allows for a clean test of these predictions due to the high level of detail on expenditure items, an exogenous fixed election schedule, and homogeneity of Portuguese local governments with respect to policy instruments and institutions. Estimation results clearly reveal the opportunistic behaviour of local governments. In pre-electoral periods, they increase total expenditures and change their composition favouring items that are highly visible to the electorate. This behaviour is consistent with an effort to signal competence and increase chances of re-election. 相似文献

The Y-chromosome polymorphism of eight STRs (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392; DYS393, DYS385) were studied in 111 unrelated individuals from the population of southwest Spain. The most common haplotype was shared by 3.6% of the sample, while 99 haplotypes were unique. The gene diversity was 0.9977. 相似文献

Suicide in children is a rare finding and is probably motivated by acts of impulsiveness. This study aims to contribute to the characterization of child suicide in a forensic perspective in the Portuguese population. Data of forensic autopsies from 2004 to 2012 related to suicide victims under 18 years were reviewed. A total of 17 cases, with a male predominance (64.7%) and a mean age of 15.24 ± 1.348 for both genders, were registered. The leading suicide method was hanging (35.3%), and a suicide note was found in 41.2%. Psychological autopsy proved to be useful in promoting a better understanding of these incidents and their antecedents. This study also offers useful information, namely the implied risk factors, for future programs of suicide research and prevention. 相似文献
