The trade in caviar has a rich and colorful history, influenced over thousands of years by many cultures, societies and in the last decades by regulation. The value of caviar is historically discovered in the context of social change, political relationships and environmental change. The role of organized crime is described, as the scarcity of caviar has offered the unique opportunity to fish illegally, smuggle and trade contraband to mainly European countries with millions in profits. This study highlights that these criminal networks manifest themselves at all levels of the trade: from the poaching areas where organized criminal groups cooperate with law enforcers and possess top-notch equipment to major smuggling operations in the hands of sophisticated criminal networks. Although due to overexploitation ‘wild caviar’ is increasingly difficult to obtain, the demand in the context of exclusivity and scarcity remains intact by the upper class society desire for edible gold.  相似文献

Identifying children's risk exposure is the first step toward mortality prevention. This retrospective study determined the causes of child fatalities in Dammam, Saudi Arabia. Death reports of children and adolescents from 1999 to 2015 (= 157) were analyzed. Boys represented most cases (69%) and there were two age peaks (1–5 years and 16–18 years). Accidents (typically immersion) defined the main death circumstance (51%) followed by homicide (25%). Only 33% of cases underwent autopsy, and the most common cause of death was head injury (27%) followed by firearm injury. Only one immersion death underwent autopsy. This study revealed important data about the risk exposure of children in Dammam and emphasizes deficient investigative procedures. Child fatality reviews comprise systematic data collection by multidisciplinary teams to determine the true risks toward children in a community. Such teams do not exist in Arab countries; therefore, strategies should be implemented to initiate them.  相似文献

Since 1991 the super-presidential regime of Islam Karimov in Uzbekistan has successfully defended the country's new independence and his authoritarian rule by cleverly enlisting the aid of outside powers such as Russia, China and the USA. With the means afforded by global export of its staple commodities, the regime has preserved stability by managing occasional conflicts with its neighbours, repressing dissenters when necessary, promulgating an ideology of multi-nationalism, and ample spending on health and educational services, as well as on government employees. The current economic crisis has meant the return of many Uzbeks from elsewhere in Asia, but the regime is trying to offset discontent with more spending.  相似文献

How do we understand the 15th amendment of the Bangladeshi Constitution that restored the principle of secularism and simultaneously (re)inscribed certain populations as outside the cultural nation? I approach this question through a close reading of the Constituent Assembly debates of 1972. The precarious state of minorities, I contend, is not a symptom of an incomplete or failed secularism but a feature of the violence inherent to the nation-state form. The Bangladeshi example suggests not only that minority is a profoundly unstable category but that some minorities are visibly critical to national self-fashioning while others must be invisibilized as national others.  相似文献

Technological innovations are by no means Pareto‐improving. I build on the argument that incumbent innovators can use political means to block rival innovations by emphasizing that the competitiveness of political system and some political institutions may diminish their ability to do so. I specify an institutional mechanism of agenda power, which provides newcomers with an improved ability to enter the game. The number of agenda power holders varies significantly among political systems, electoral systems, and administrative structures. With a sample of about 100 countries and across 20 years I show that politically competitive regimes, majoritarian electoral rules, and federal structures supply more holders of agenda power in comparison to their counterparts and, other things being equal, produce more innovations.  相似文献

The majority of research on intimate partner violence (IPV) has addressed male-to-female violence, although a small but growing body of literature has developed that explores males victimized by female partners. This study used data from the National Crime Victimization Survey from 1987 to 2003 to examine male victimization by comparing the nature of violence to female victimization and by exploring the effect of perpetrator arrest on preventing revictimization. The sample was comprised of 2,462 female and 298 male victims. Study variables included gender, arrest, revictimization, type of violence, injury, and use of a weapon. Results showed that men were victimized by IPV less frequently than women and received fewer injuries, although they were more likely to experience more severe violence. Police arrested female perpetrators, but generally only if injury was involved; however, arrest did not reduce male victims’ chance of revictimization.  相似文献
