Short tandem repeats (STRs) play an essential role in forensic genetics due to their high degree of polymorphisms, wide distributions and easy detection method. In this study, allelic frequencies and forensic statistical parameters of the 19 autosomal STR loci in a Kazak ethnic group were calculated, and its genetic relationships with reference populations were assessed in order to understand population structure better and enrich population genetic data for forensic practice in Chinese Kazak ethnic group. There were 226 identified alleles with the corresponding allelic frequencies ranging from 0.0008 to 0.5295 in the 628 unrelated healthy Kazak individuals in Xinjiang Uygur Autonomous Region. All autosomal STRs were conformed to the Hardy-Weinberg equilibrium after Bonferroni’s correction. The cumulative power of discrimination and the combined probability of exclusion of all the 19 autosomal STRs were 0.999 999 999 999 999 999 999 997 162 and 0.999 999 994 484, respectively. Furthermore, the DA distances and Fixation index values of pairwise populations, principal component analysis, multidimensional scaling analysis, phylogenetic tree analysis and structure analysis were conducted to probe the genetic relationships between the Kazak group and other reference populations. The population genetic results showed that these 19 autosomal STR loci were characterised by high genetic diversities in the Kazak group. Furthermore, the studied Kazak group had close genetic relationships with the Uyghur group and the Uzbek group. The present results may facilitate understanding the genetic background of the Chinese Xinjiang Kazak group. 相似文献

This study investigates the impact of governance index and gross fixed capital formation on the economic growth of Brazil, Russia, India, China and South Africa (BRICS) using annual data from 2002 to 2019. This study employs Fixed Effect Model, Driscoll and Kraay standard error with fixed effect, Fully Modified Ordinary Least Square, Dynamic Ordinary Least Square (DOLS) and Panel Dumitrescu Hurlin Causality test. The study has divided the variables into two models where model I includes the impact of governance index (jointly) on economic growth while model II examines the impact of governance index on economic growth individually. The findings demonstrate that the governance index, gross fixed capital formation, population, control of corruption, and governance effectiveness have a positive and significant impact on economic growth, whereas regulatory quality showed a significant and negative impact on economic growth. Furthermore, regarding the Panel test, we notice the presence of unidirectional causality among the constituent variables. Therefore, this study suggests that the government should encourage economic development in the BRICS countries and move away from outdated ideas and poor institutional quality in favor of a new comprehensive reform to achieve excellent governance, population growth control, labor law changes, and corruption control. 相似文献

At the stage of the development of a new social welfare system in Ukraine, it is important to investigate all possible models and develop recommendations for the implementation of the most effective ones. The relevance of this paper lies in the study of the legal framework that operates in Ukraine and the possibilities of its improvement and consolidation into a more specific regulation. The purpose of the research was to study the principles of the social welfare system in Ukraine and to study foreign practices of the social welfare system. Within the framework of this study, the existing systems and models of social welfare systems in different countries were analyzed. The study identifies the most positive examples of social welfare policy for implementation in the current legal framework to improve and enhance the quality of social services in Ukraine. The analyzed foreign practices helped to identify the most effective models of social security. It was concluded that with the successful redistribution of funds, the introduction of a system of audit and control of social assistance financing, as well as being guided by foreign experience, Ukraine will be able to build a social welfare system that would satisfy all of the existing social needs of citizens. 相似文献
