人口老龄化压力下的现实选择--低龄老年人力资源开发的思考 总被引:2,自引:0,他引:2
本文对老年人力资源开发的一些问题做了探讨,指出由低龄健康老人组成的老年人力资源是人力资源的重要组成部分,开发这部分人力资源对于缓解人口老龄化的压力具有重要的意义.老年人力资源开发状况受经济发展水平、继续工作的机会、社会配套制度与机构、身体状况和文化素质的制约,所以老年人的就业思路应当与老年人的心理、生理特点相适应.老年人离退休后继续工作,并不存在与年轻人争夺岗位的问题.开发老年人力资源应注意积极实现老年自养,同时也需要全社会的关注与支持,尤其需要各级政府采取有力措施. 相似文献

人口问题是北京市发展中面临的一个突出问题。区域协调发展是北京缓解人口压力、保持可持续发展的一项重要措施。本文对新中国成立以来北京市流动人口规模的变化和相关政策及影响进行回顾和审视,进而对北京市流动人口的基本现状和主要特点进行分析,在此基础上,探讨了京津冀协同发展对北京市流动人口规模可能产生的影响,期望对正确认识和解决北京市的流动人口问题有所裨益。 相似文献

在国家“六稳”、“六保”的政策目标下,稳定房价具有较大现实意义。基于中国267个地级市2006-2018年的面板数据,通过联立方程模型实证研究地方财政支出、人口迁移以及预期对房价的影响。结果显示,市场对房价上涨的预期是推升房价上涨的主要因素,此外,全国层面的房价受到地方财政支出资本化的正向作用,东、中部地区房价受到人口迁移数量的显著影响,西部地区房价受到第三产业占比的支撑。因此,稳定房价的关键途径是维持购房者的市场信心,确保人口流入有助稳定东、中部地区房价?确保第三产业发展则是 稳定西部房价的重要途径。 相似文献

Red deer is the most valuable game of the fauna in Hungary, and there is a strong need for genetic identification of individuals. For this purpose, 10 tetranucleotide STR markers were developed and amplified in two 5‐plex systems. The study presented here includes the flanking region sequence analysis and the allele nomenclature of the 10 loci as well as the PCR optimization of the DeerPlex I and II. LD pairwise tests and cross‐species similarity analyses showed the 10 loci to be independently inherited. Considerable levels of genetic differences between two subpopulations were recorded, and FST was 0.034 using AMOVA. The average probability of identity (PIave) was at the value of 2.6736 × 10?15. This low value for PIave nearly eliminates false identification. An illegal hunting case solved by DeerPlex is described herein. The calculated likelihood ratio (LR) illustrates the potential of the 10 red deer microsatellite markers for forensic investigations. 相似文献

武汉城市圈的户籍制度改革对于推动圈内的经济发展及实现中部崛起的战略具有重要意义。目前武汉城市圈内各城市间的户籍制度存在差异、人户分离现象严重,公民的许多权益难以保障,城市化进程受阻,因而应从渐次放宽户口迁移限制、健全以居住地为主的户口登记制度,推进城市圈内人口信息现代化的进程,使武汉城市圈户籍制度改革更臻完善。 相似文献

AbstractThe contemporary global health agenda has shifted emphasis from mapping disease patterns to calculating disease burden in efforts to gauge ‘the state of world health’. In this paper, we account for this shift by showing how a novel epidemiological style of thought emerged in the closing decades of the twentieth century. As is well known, the compilation and tabulation of vital statistics – death-rates, birth-rates, morbidity rates – contributed to the birth of the ‘population’ in the eighteenth and nineteenth centuries. The population is reformatted from the middle of the twentieth century by ‘modified life tables’ made up of disability weightings, health state valuations, quality of life scores, disease burden estimates, etc. The problem of morbid death gives way to that of morbid living, made calculable through a metrics of ‘severity’, ‘disability’ and ‘impairment’. A series of new indices and scales (e.g. the QALY and DALY) has contributed to a governmentalization of living, in the course of which the social and personal consequences of living with disease come to be an object of political concern, and made knowable, calculable and thereby amenable to various strategies of intervention. We conclude by showing how this style of epidemiological thought has generated a new global visibility for brain disorders as their impact on individuals, health care systems and nations are calculated in novel ways. 相似文献

This analysis of citizenship identity among Sami living in core Sami areas in Norway clearly shows that the Sami population feel more closely connected to their local communities than is the case for non-Sami living in the same areas and for the Norwegian populace as a whole. Some significant differences also emerge as regards citizenship identity between Sami who have chosen to be registered in the Sami electoral roster and those who are not registered – in terms of identification with different identity groups, affiliation with different territorially defined areas and the intensity of their Sami identity. However, none of our findings suggest that the total Norwegian citizenry is an unimportant identity group for the Sami population, or that the Sami do not feel affiliated with Norway as a whole. The fact that the perceived content of Norwegian-ness does not seem to include elements that are incompatible with the perceived content of Sami-ness also indicates that it may not be particularly difficult for individuals to combine Sami and Norwegian identity. 相似文献

The chemical composition of a fingermark potentially holds a wealth of information about the fingermark donor, which can be extracted by immunolabeling. Immunolabeling can be used to detect specific components in fingermarks; however, to be applicable in the forensic field, it should be compatible with commonly used fingerprint visualization techniques. In this study, the compatibility of immunolabeling with two different fingerprint visualization techniques, magnetic powdering and ninhydrin staining, was investigated on fingermarks deposited on glass and on nitrocellulose membranes. With dermcidin as antigen of interest, immunolabeling was performed successfully on all developed fingermarks. We can conclude that immunolabeling is compatible with magnetic powdering and ninhydrin staining, which can be of great forensic value. 相似文献
