文中提出了基于层次分析法的城镇化发展水平模糊综合评价方法,可以提高我国城镇化水平评价的有效性。首先建立起城镇化评价指标体系,然后运用层次分析法确立各评价指标的权重,针对城镇化发展水平评价的特点,采用＂最大—最小值法＂确立各指标对城镇化评价的隶属度函数,运用模糊综合评价方法,对重庆市和全国的城镇化发展水平进行综合评价。 相似文献

为了降低规模化屠宰场非洲猪瘟(ASF)的传播风险,建立ASF风险评价指标体系,探索模糊层次分析法在ASF风险分级中的实际应用。采用德尔菲法,从宰前、宰中、宰后、日常管理4个方面选出12项二级指标,41项三级指标为风险因子,建立了多层次风险评价指标体系;利用层次分析法计算各评价指标的权重,再通过模糊综合评价进行多层次综合判断,实现定性分析与定量分析有机结合。运用该模型进行实证分析,被评价屠宰场ASF风险水平为"中等",与实际情况一致,需要从日常清洗与消毒、生猪车辆管理、待宰管理等方面加强改善。研究构建的模糊层次评估模型可为监管机构实施风险分级管理提供依据,为屠宰企业加强自身ASF防控对策指明方向。 相似文献

Canada has four veterinary schools, from which approximately 325 veterinarians graduate each year. Curricular offerings in zoological medicine consist of limited core material and a variety of internal and external electives pursued by students with particular interests. Several electives are offered jointly by and rotate among the existing schools. All schools offer graduate programs that encompass some aspects of zoological medicine. A fifth veterinary school, expected to open in 2007, will have a stronger focus on ecosystem health and zoological medicine. In Canada, the most effective method of increasing educational opportunities in zoological medicine is likely through enhanced collaboration among the five schools. Employment opportunities exist in private veterinary practice and at universities, research establishments, provincial or federal governments, and zoological gardens and safari parks. Increasing recognition of the importance of ecosystem health and of the relevance of wildlife diseases to public and domestic animal health will likely result in additional opportunities for veterinarians with an interest in and knowledge of zoological medicine. 相似文献

The American College of Zoological Medicine (ACZM) is dedicated to excellence in furthering the health and well-being of both captive and free-ranging wild animals. Currently there are 14 ACZM-approved residency programs in zoological medicine. In addition, eight non-approved residencies and 15 internships in North America provide training opportunities in this field. This article outlines some of the training opportunities for both veterinary students and graduate veterinarians that would best position them for entry into a zoological medicine training program. Although there is a growing number of opportunities for individuals to serve in captive and free-ranging wildlife health positions, existing training programs are inadequate to meet these needs. It is also acknowledged that there is an increasing number of veterinary students entering veterinary schools with an interest in zoological medicine and that the job market is still limited. However, positions and opportunities in zoological medicine are available for those individuals with the drive, dedication, and passion to succeed. 相似文献

Based on the law of animal welfare and on the EU-rule about keeping of wild animals in zoological gardens 15 zoological gardens in Brandenburg were inspected by a temporary team consisting of one veterinarian from the state office of feeds and agriculture, the local authorized veterinarian and one director of the zoogardens. Data of every zoological garden at first were recorded by special lists of queries. So it was possible to estimate the keeping conditions and to realize deficiencies and the main problems. During the local inspection these data were controlled and the structure of keeping units as well as the conditions and behaviour of the animals were evaluated. Every unit was evaluated taking into consideration all points of view. If necessary proposals for improvements were made which were to enforce by the local authority. Furthermore the documentation and the economic areas were inspected. The number of kept species and animals was relatively low. Only two zoological gardens were to classify as mean ones. The majority of the fences and aviaries corresponded with the minimal demands of the today rules resp. was larger in the dimension and space. There were very nice keeping units, but also some deficiently in the structure or in the quality of the ground. By some photographs positive and negative examples are demonstrated. The feeding and also the veterinary service were on high level. The team found out that staffs of the zoogardens had a positive position to animal welfare. Step by step they improved the keeping conditions. The central inspection by a multi-professional team was estimated positively and should be repeated in certain intervals. The used lists of queries were suitable. The valid rules and guide lines should be revised in near future. 相似文献

There is a decrease in the number of elephants kept in European zoological gardens and circus companies. In the future the import of animals will only be possible for holders which are able to keep family-groups of elephants under species-specific conditions. This will not be possible under circus conditions. This article will describe some problems observed in elephant holdings in zoological gardens and circus companies. 相似文献

Advances have been made in expanding veterinary curricula to deliver basic key knowledge and skills necessary for provision of health care to captive and companion non-domestic or non-traditional species in the veterinary colleges of the United States and Canada. These advances were in large part facilitated by the deliberations and recommendations of the White Oak Accords. Though a five-year review of curricular opportunities at US and Canadian veterinary colleges shows that progress has been made in implementing the recommendations of the White Oak Accords, there remains room for improvement. The broadly comparative and health-maintenance basis of zoological medicine contributes critically to the potential for veterinary medicine to make important contributions to the concept of the integrated health of the planet. Emergence of key zoonotic and production-animal diseases derived from and within wildlife populations since 2000 has increased awareness worldwide of the importance of zoological medicine in protecting both production livestock and public health. These areas are addressed in elective curricula at colleges emerging as centers of excellence in zoological medicine, but it is critical that core curricula in zoological medicine at all schools be strengthened to include these important areas to prepare our DVM/VMD graduates to protect companion-animal, production-animal, and public health. 相似文献
