This research explores the challenges encountered in integrating competency modeling (CM) in talent management (TM) and proposes a framework for this integration. Using CM practices and TM implementation perspectives, a framework was developed for integrating CM in TM. Furthermore, this research used a multiple cross-case study design approach involving organizations practicing CM. In-depth interviews with practicing HR managers helped identify the challenges and issues related to CM integration in TM. To address these challenges, a framework involving multiple alignments with TM was developed. The dimensions of this alignment comprise functionality, information system, capability, governance, and contextual integration. The integration aspects of CM in TM, which have been discussed in detail, will assist researchers and practitioners. 相似文献

旋转映射信号将编码比特旋转移位后映射为符号,同时采用了隐性交织、加扰等技术,具有交织复杂度低、信道效率高等特点,是一种典型且使用较为广泛的短波通信信号。针对第三方接收条件下,频率选择性衰落造成该类信号难以有效接收的问题,推导了该类信号的软符号解映射、映射方法,提出了一种针对该类信号的多天线联合Turbo均衡算法,实现了软信息在均衡与译码之间的迭代交换。典型短波信道下的仿真结果表明,迭代4次后的两天线联合Turbo均衡在10-5误码率时相对两天线硬判决译码提供了约4 dB的增益,相对两天线软判决译码提供了约1 dB的增益,在10-4误码率时相对单天线Turbo均衡提供了约5.5 dB的增益。 相似文献

About a quarter of long-term care insurance (LTCI) policy holders aged 65 let their policies lapse before death, forfeiting all benefits. We find that lapse rates are substantially higher among the cognitively impaired in the Health and Retirement Study. This generates a pernicious form of dynamic advantageous selection, as the cognitively impaired are more likely to use care. Simulations show that an inappropriately optimistic asset drawdown path further increases the individual welfare cost of unanticipated lapses. Meanwhile, we find evidence of a significant but very small role for either strategic or financial motives for lapsing. 相似文献

This study examines the effects of changes in household economic conditions on cognitive function using individual panel data from the National Survey of the Japanese Elderly. This study captures the objective and subjective economic conditions and examines which aspects of economic conditions affect cognitive function. The results demonstrate that deterioration in economic conditions damages cognitive function. In particular, objective economic conditions measured by income affect the cognitive function of Japanese men. This study also assesses possible pathways through which economic conditions affect cognitive function. 相似文献

Thanks to the advances in public health and medical sciences, the increasing of elderly has become a structural phenomenon in Europe and the rest of the World. This demographic age shift highlighted severe doubts about the sustainability of healthcare systems which see adult people as a burden rather than, if they are healthy and active, as an advantage for a country’s economic development. Safeguarding older people from infections is crucial, but supporting them during health emergencies is even more critical. Older adults, for example, became more at risk of death during the COVID-19 pandemic. Thus, the balance previously achieved between age-related diseases and healthy quality of life went under higher pressure. As a result, the potential impact of ageing on healthcare expenditure is increasingly debated. Starting from this background, we propose a bibliometric study based on word embedding techniques to identify the drivers that could influence this relationship and track their evolution in the health policy debate. The main findings of our research underline that given the upward impact on the growth in health spending due to population ageing, policies oriented to improve their access to health services through new technologies could better meet the elderly needs, moderating the cost growth. Protecting the health of older adults represents, in fact, a challenge for governments as well as proof of the quality of health systems management, especially during severe outbreaks such as the one caused by the coronavirus. 相似文献

基于社会嵌入理论,依据实地调研数据,采用偏最小二乘结构方程模型,考量主观规范、认知态度对养老服务消费意愿的影响。结果显示:老年人感受到的主观规范越强,其养老服务消费意愿越强,尤其在弱关系场景。主观知识在网络密度与养老服务消费意愿关系中起中介作用,46.99%的网络密度影响通过信息增益实现。异质性检验结果显示:网络密度对60岁以上老年群体的积极影响增强,而网络位置影响转为消极;主观知识对城市地区、高收入、高教育水平老年群体的积极影响更显著,低收入老年消费者群体养老服务消费决策更依赖于社会网络带来的资源改善。鉴于此,可培养老年社群宣传代理人,强化社会规范影响;结合多层次媒体嵌入,营造养老服务消费氛围;实施城乡差异化养老服务推广策略,提升养老服务消费意愿。 相似文献
