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。     

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.     

Oiling the wheels? Flexible labour markets and the migration industry

ABSTRACT

The growing commercialisation of migration, often through a multiplicity of labour market intermediaries, is an issue of increasing academic interest. We seek to contribute to an emerging research agenda on the migration industries by exploring how one of the key actors that constitutes it, recruitment agencies, sits at the nexus between flexible labour market structures and migrant labour. Interviews with U.K. labour providers and low-wage employers form the evidence base for an analysis of the strategies developed by recruiters to derive commercial gain from connecting the so-called ‘supply’ and ‘demand’ sides of the flexible international labour market. We seek to contribute to understandings of the analytical categories within migration systems by illustrating how the migration industry interacts with other key stakeholders to structure international migration.     

高校图书馆人力资源管理现状及其对策

图书馆是高校教学科研高质量进行的重要保障之一.然而高校图书馆多年来一直都被束缚在传统的人事制度和资源分配制度之下,改革进度不大,严重影响了图书馆的建设.笔者认为高校图书馆的建设进入到一个"以人为本"的阶段,以读者为中心开展多种服务,满足多种需要;以馆员为中心,提供宽松的环境发挥其主观能动性和创造性,从而促使高校图书馆进一步发展.而这一切都要先从图书馆的人力资源建设做起.     

Efficient Bayesian inference in generalized inverse gamma processes for stochastic volatility

This paper develops a novel and efficient algorithm for Bayesian inference in inverse Gamma stochastic volatility models. It is shown that by conditioning on auxiliary variables, it is possible to sample all the volatilities jointly directly from their posterior conditional density, using simple and easy to draw from distributions. Furthermore, this paper develops a generalized inverse gamma process with more flexible tails in the distribution of volatilities, which still allows for simple and efficient calculations. Using several macroeconomic and financial datasets, it is shown that the inverse gamma and generalized inverse gamma processes can greatly outperform the commonly used log normal volatility processes with Student’s t errors or jumps in the mean equation.     

个人收入同步增长的保障制度设计：15城市证据

我国灵活就业群体规模巳占新增就业总量70％以上,该群体有工作但不固定,有收入但不稳定。先后四次对我国15个城市的灵活就业群体进行调研后认为,确保我国灵活就业群体个人收入同步增长,应从建立灵活就业群体的工资集体协商制度、构建新型式社区工会、建立雇员平等参股制度、搭建灵活就业群体失业救助平台、构建灵活就业人员失业扶持的慈善基金制度等方面着手。
