沈阳市老年人口现状及其养老保障模式的构建

沈阳作为一个重工业城市 ,在其二次创业过程中人口老龄化问题日益突出 ,因此 ,掌握沈阳市老年人口的生活状况 ,构建适合沈阳市老年人口现状的养老保障模式 ,已经成为沈阳市社会养老保障体系改革的重要内容。     

上犹社溪方言实词的兼类与活用

当语言中的一个新词诞生以后 ,只要表示与之相关的动作变化或状态的动词或形容词没有产生 ,就很可能直接用这个词来表示这种相关的动作变化或状态。因此 ,词的兼类是各种语言或方言、或各个不同时期的同一语言中常见的现象。在语言的发展史上 ,尽可能减少词的兼类现象 ,特别是通过形态变化等手段把兼类的词分化为不同的词 ,还有些词存在活用现象 ,显得很有地方特色。从此角度说 ,客家方言保留着较多的古语痕迹。     

驻村干部参与乡村治理的柔性嵌入机制

柔性嵌入是驻村干部通过沟通、对话、协商参与乡村治理的管理实践。柔性嵌入式治理并非单纯的行政制度吸纳与整合,而是包括文化嵌入、认知嵌入、关系嵌入在内的多维柔性嵌入的互动与治理的过程。从辽宁省X县的治理实践来看,驻村干部参与乡村治理仍受根深蒂固的刚性治理思维、运转不畅的民主协商机制、薄弱的乡村社会资本、匮乏的村庄公共精神等现实因素掣肘。需要从转变刚性治理观念、运用情感治理技术、完善基层协商机制、挖掘乡村内生资源、培育村庄公共精神等层面进一步激活柔性嵌入机制,持续提升驻村干部参与乡村治理效能。     

基于《巴塞尔Ⅲ最终方案》的弹性杠杆率监管研究

弹性资本充足率监管加刚性杠杆率监管存在机理性缺陷。弹性资本充足率监管会影响刚性杠杆率监管的效果,刚性杠杆率监管也不能体现杠杆累积在时间维度和空间维度风险的变化。若引入弹性杠杆率缓冲,刚性杠杆率监管加弹性资本充足率监管的机理性缺陷就可以避免。因此,有必要实施弹性杠杆率监管,杠杆率的弹性化程度与银行的系统重要性程度相对应。     

At the threshold of retirement: From all-absorbing relations to self-actualization

To investigate the complexities of the retirement process, the present article draws on a case study of Eva, a Swedish woman who “awakened” from all-absorbing relations. It considers the ways in which retirement can enable liberation from patriarchal kinship structures and embodied values of respectability. The aim is to illuminate how deep, embodied values can become conscious and explicit during precarious life situations and transitional phases. The relation between the Swedish welfare state, an I-we balance, and gender equity values are illuminated. These analytical dimensions support the analysis by providing insights into the ways in which individuals embody and use cultural and social structures when they aim to manage unpredictability and to create change toward self-actualization.     

Backward capacity-filtering for electronics Fabs

In electronics Fabs such as semiconductor Fabs and liquid crystal display (LCD) Fabs, which are capital-intensive, finite-capacity planning is critical to achieving full-capacity production and on-time production. However, existing finite-capacity planning methods do not adequately reflect the actual capacity profiles of an electronics Fab. In this paper, we propose a new Fab-level capacity-filtering procedure to generate finite-capacity plan: a backward capacity-filtering procedure for generating finite-capacity release plan. When developing the Fab-level filtering procedures, we use stage-level capacity-filtering algorithms as a key building block. In this study, we enhance the previous capacity-filtering algorithms proposed by one of the authors in order to facilitate the practical requirements of electronics Fabs. We apply the proposed capacity-filtering method to a modern LCD–TFT Fab in Korea. Performance analyses demonstrate that the proposed method is superior to existing methods.     

Bayesian adaptive dose‐escalation designs for simultaneously estimating the optimal and maximum safe dose based on safety and efficacy

The main purpose of dose‐escalation trials is to identify the dose(s) that is/are safe and efficacious for further investigations in later studies. In this paper, we introduce dose‐escalation designs that incorporate both the dose‐limiting events and dose‐limiting toxicities (DLTs) and indicative responses of efficacy into the procedure. A flexible nonparametric model is used for modelling the continuous efficacy responses while a logistic model is used for the binary DLTs. Escalation decisions are based on the combination of the probabilities of DLTs and expected efficacy through a gain function. On the basis of this setup, we then introduce 2 types of Bayesian adaptive dose‐escalation strategies. The first type of procedures, called “single objective,” aims to identify and recommend a single dose, either the maximum tolerated dose, the highest dose that is considered as safe, or the optimal dose, a safe dose that gives optimum benefit risk. The second type, called “dual objective,” aims to jointly estimate both the maximum tolerated dose and the optimal dose accurately. The recommended doses obtained under these dose‐escalation procedures provide information about the safety and efficacy profile of the novel drug to facilitate later studies. We evaluate different strategies via simulations based on an example constructed from a real trial on patients with type 2 diabetes, and the use of stopping rules is assessed. We find that the nonparametric model estimates the efficacy responses well for different underlying true shapes. The dual‐objective designs give better results in terms of identifying the 2 real target doses compared to the single‐objective designs.     

Using Work Values to Predict Post‐Retirement Work Intentions

Work values might be proximal predictors of individuals' late‐career intentions because they serve as guiding principles for the selection, evaluation, and justification of vocational behavior. The purpose of this study was to examine the relationship between work values and post‐retirement work intentions. The authors investigated individual work values within the structure of 4 higher order values elaborated on by Schwartz et al. ( 2012 ). Relationships between work values and 4 types of post‐retirement work intentions were examined. Data from 1,071 employees of a German logistics company were used to test the hypotheses. The results of a structural equation model indicated that work values were differentially related to the 4 types of post‐retirement work intentions. The identified work value–work type combinations add to the literature on post‐retirement work. Practice implications for promoting positive individual and organizational outcomes are drawn from the results.
