Phenotypic and genotypic characteristics of the cat can be obtained from single nucleotide polymorphisms (SNPs) analyses of fur. This study developed miniplexes using SNPs with high discriminating power for random‐bred domestic cats, focusing on individual and phenotypic identification. Seventy‐eight SNPs were investigated using a multiplex PCR followed by a fluorescently labeled single base extension (SBE) technique (SNaPshot®). The SNP miniplexes were evaluated for reliability, reproducibility, sensitivity, species specificity, detection limitations, and assignment accuracy. Six SNPplexes were developed containing 39 intergenic SNPs and 26 phenotypic SNPs, including a sex identification marker, ZFXY. The combined random match probability (cRMP) was 6.58 × 10?19 across all Western cat populations and the likelihood ratio was 1.52 × 1018. These SNPplexes can distinguish individual cats and their phenotypic traits, which could provide insight into crime reconstructions. A SNP database of 237 cats from 13 worldwide populations is now available for forensic applications.  相似文献

环境权与人权问题的国际视野   总被引:1,自引:0,他引:1

环境权可以视为第一代人权中的生命权、私人生活权、财产权,由此可以促使政府保护生命和财产免受环境侵害,但这会产生人类中心主义问题;作为第二代人权,能够赋予环境质量以同其他经济、社会与文化权利相当的法律地位,使其优先于其他无权利依据的客体,但是很少对这类人权进行司法;作为集体权利有环境保护的意义,例如保护少数族裔文化和土著居民。国际法上环境权作为实体权利还未建立起来,作为程序性权利体现为公众对环境事务的知情权,决策参与权,司法救济权。通过人权保护环境,其优点在于人权与环境权相比是一项确定的权利,人权法院裁判了一些有环保意义的案子,缺点在于与人无关的环境本身的损害得不到保护,无法进行公益诉讼。  相似文献

Analysis with commonly available STR kits can sometimes fail to produce sufficient information in immigration cases containing only one parent. In these cases, not only does paternity/maternity need to be assured, but also other possible relationships dismissed (e.g. avuncular relationships).We have taken more than 50 of these cases and investigated which type of additional marker produces the greatest benefits: 48 SNPs or 6 additional informative STRs (including 5 additional markers from the new European extended set). The results of this analysis show the SNPs to be of greater value.  相似文献

The purpose of this research is to explore the impact of occupational stress on job performance of police employees. We theorized and tested the role of career satisfaction in the relationship between occupational stress and job performance as an underlying psychological mechanism. Primary data have been collected from 271 police employees working at AJ&K Pakistan. Results of this research study have shown that occupational stress is negatively related to career satisfaction, in‐role performance, and extra‐role performance of police employees. Moreover, career satisfaction mediates the relationships between occupational stress and in‐role and extra‐role performance of police employees. This research study has called researchers' and policy makers' attention towards an important issue of occupational stress in the police profession. The research will play an important role in compelling the top management, authorities, policy makers, and government officials of police to ponder over the issues of occupational stress aimed at enhancing the job performance including in‐role and extra‐role performance of police employees.  相似文献

Economists have argued that role of agriculture is pivotal for economic development of the nation. Worldwide studies have shown that agriculture sector is more effective in reducing hunger and poverty than other sectors. This study is an attempt to ascertain the importance of agriculture in the economic growth of West Bengal. Agriculture, being the source of livelihood and supplier of raw material to various industries, triggers economic growth of the nation. This paper exhibits how agriculture has contributed to West Bengal's economic excellence using empirical data and a cointegration analysis. The role of agriculture is examined on four contributions: (a) product contribution (forward linkage), (b) market contribution (backward linkage), (c) factor contribution, and (d) foreign exchange contribution. The composition and growth of the sectors and its association with other sectors is analyzed using time series analysis. Findings of the study revealed that agriculture sector has appeared as an important contributor to drive West Bengal economic growth even after declining share in gross state domestic product over the years. Empirical analysis reveals that agriculture is having long run causal linkages with industry, services, and overall economic growth in West Bengal.  相似文献

This article reviews the efforts of the Government of Bangladesh aimed at reforming the public sector financial management system as part of overall public administration reforms through a technical assistance project jointly sponsored by the government and the Department for International Development, Government of the UK. It has evolved through initial setbacks into a highly successful project delivering tangible outputs over the last three years, with prospects for future extension until reforms are internalized and become self‐sustaining. Attempts have been made in this article to analyse and evaluate the underlying reasons for the problems in the first year of implementation as well as the factors that contributed to the recovery of the image of the project and its continuing successes in successive phases. The article highlights the lessons learned from the project in its bad as well as good times and suggests that this experience can be of great value to those undergoing the same type of reform experiment.

Although suicide bombing is a historical phenomenon, there has been a recent upsurge in such incidents. In Pakistan, over the last year, more than 1,000 people have been killed in suicide bombing incidents. Assessing the attitudes and perceptions of people toward suicide bombing can help understand some of the root causes of this phenomenon. In this pilot study, we conducted a cross-sectional survey of people (N = 215) in Karachi, Pakistan, to assess their attitudes and perceptions toward suicide bombing. The majority of the respondents condemned suicide bombing and disagreed with the notion that Islam or any other religion supports it. Belonging to the Sunni Muslim sect and strong adherence to religion predicted support for suicide bombing. The majority believed suicide bombing to be a result of religious fundamentalism. Opinion was divided as to whether suicide bombers have an underlying psychiatric illness. Further studies with larger sample sizes are needed to determine the attitudes and perceptions of the Pakistani population regarding this important issue.  相似文献
