人力资源个体价值计量方法——当期实现价值系数法

由于人力资源自身具有复杂性、不确定性的特点,使得人力资源价值难以计量。而准确的计量人力资源价值,尤其是人力资源的个体价值是人力资源会计能否实施的关键因素。针对这个问题,本文在分析前人成果的基础上提出了人力资源当期实现价值系数法计量模型。并通过实例验证了计量模型的实用性。     

关于推进我国由核大国向核强国迈进的探讨与思考

论文阐述了推进我国核大国向核强国迈进的背景、规划、核战略产业、军民融合海陆空领域的发展。首先题解我国核大国、强国的顶层设计、国外背景、10大产业的大国强国方向;进而阐明了我国已步入核电大国行列,在役在建设核电站进入世界第三位,但核电在国际国内能源、电力中比重很小,迈向核电强国任务艰巨;进而阐明举全国之力做强我国核工业,建设更先进的核潜艇,研发中国战略重器核航空母舰;建立强大有后处理的核燃料循环,打造“中国造”华龙1号,全产业链走出去;实施一批重大工程建设,推动核科技进步,继续研发、部署小堆项目建设;抓紧以核电代煤、治霾、减碳、供热的开发工作;加大核科技在农学、医学、科研、军工的应用。认真贯彻《核安全法》确保核工业安全发展,健全完善核应急体系,推动核安保能力提升,不断完善核安全结构和核安全系统的顶层设计,保障核工业安全万无一失。抓好军民深度融合国家战略发展,军民对接,使命承担,发展军民融合产业。     

双向FDI与经济增长的实证研究

从双向FDI的角度分析OFDI和IFDI与经济增长的关系。选取双向FDI对经济增长的3个主要影响因素,分别对双向FDI与GDP、投资、净出口和产业结构的关系进行实证分析。研究发现:双向FDI对于GDP和投资都具有拉动作用;IFDI对投资的影响滞后4期才能产生,对净出口的增长起到正向促进作用;OFDI的扩大不利于净出口的增长;双向FDI与三次产业都存在较强的灰色关联度。据此,提出改善对内对外投资环境、发挥双向FDI对固定资产投资和净出口的促进作用、强化双向FDI对产业结构的调整作用等建议。     

基于累积前景理论的多资产投资组合优化与实证研究

基于CPT视角的多风险资产投资组合模型,探讨投资者面对不同投资风险时的心理变化以及心理变化对其投资策略的影响。通过选取不同超额收益率及波动率水平的股票,测试投资策略对于风险态度指标的敏感度。研究表明,投资者面对不同风险具有明显地心理变化,并且其心理变化对投资策略具有显著的影响。具体表现在几个方面：投资者面对不确定收益时,表现出风险厌恶,面对不确定损失时,表现出风险偏好;投资者将无风险资产的投资收益作为心理参考点,所做的投资决策与相对于此参考点的相对财富水平的变化有关,而不是与传统理论中的绝对财富变化量相关。     

讲学与传道: 马一浮与国立浙江大学

抗日战争期间,国立浙江大学被迫西迁,马一浮应浙大校长竺可桢之请为浙江大学师生开设国学讲座,为浙大创制校歌,这段历史成为浙大校史上光辉的一页。但相关文献和档案却显示,马一浮与浙江大学的交往充满各种误会与纠结,浙大险些因此错过这位“士林宗仰”的国学大师;而走过国立浙大的马一浮亦在他唯一任教的大学里,利用各种机会引导学生摒弃实用主义的现代工业观,回归对文化根本的关注,尽管讲学效果与其预想相距甚远。马一浮在浙大讲学并传道,结集而成的《宜山泰和会语》是马一浮一生讲阐六艺国学最集中的部分,由此完成了更为高迈、通贯的学术思想和学术人格的构建,并以一场场思想与精神的盛宴,寄予浙大很深的希望。     

明代宫廷书画收藏考略

明代宫廷的书画收藏十分丰富,嘉靖以后虽多有散出,但仍具有一定规模,直至明清鼎革之际宫廷所藏书画才散佚殆尽。明代宫廷所藏书画主要包括接收前代遗存、查抄籍没书画以及帝后臣工新创作书画几个部分。宫廷所藏书画主要由宦官机构司礼监负责保管,存放于质慎库中;另有部分历代帝王、君臣画像由印绶监保管,存放于古今通集库中。明代中叶以后,宫廷收藏书画通过充抵官员俸禄、偷窃等方式大量流散出宫,但同时也存在一定的补充和回流。明清易代之际,宫中所藏书画散佚殆尽,这为明末清初私人收藏家群体的崛起提供了机遇。     

Socio‐economic stratification of English in globalized landscapes: A market‐oriented perspective

Globalization has dramatically altered the urban societies of Amsterdam and Brussels over recent decades, with intensified socio‐economic inequality, unprecedented levels of multilingualism and the increasing importance of English. In this paper, I examine the use of English in the linguistic landscape of socio‐economically stratified commercial shopping streets in these two second‐tier global cities. I adopt a market‐oriented, contextualized approach to quantitative and qualitative variability in how English emerges in these particular commercial ‘linguistic markets’. McDonaldization in midscale shopping streets occurs alongside downscale and upscale uses of English which are more susceptible to local commercial dynamics, in particular in Brussels. As such, global English in these single city contexts emerges as a heterogeneous and scaled phenomenon shaped by specific local commercial and linguistic market conditions.     

RESEARCHING RELATIONSHIPS FROM AN ATTACHMENT PERSPECTIVE: THE USE OF BEHAVIOURAL,INTERVIEW, SELF‐REPORT AND PROJECTIVE MEASURES

Having demonstrated its credentials as one of the more elegant and robust conceptualisations of human relationships, attachment theory has considerable relevance to social work. Attachment‐based research has flourished over the past few years and it now includes an impressive array of studies across the lifespan. This article considers four different measures used in attachment‐based research, although more discussion is devoted to interview and projective measures because they specifically embrace a psychodynamic approach in their design and analytic focus. The aim of the article is to provide a brief overview of each measure and to offer some illustrative examples using practice‐related material.     

Mixed integer (0–1) fractional programming for decision support in paper production industry

This paper presents an effective and efficient method for solving a special class of mixed integer fractional programming (FP) problems. We take a classical reformulation approach for continuous FP as a starting point and extend it for solving a more general class of mixed integer (0–1) fractional programming problems.To stress the practical relevance of the research we focus on a real-life application in paper production industry. The constantly advancing physical knowledge of large scale pulp and paper production did have a substantial impact on an existing DSS in which mixed integer (0–1) fractional programming is introduced. We show that the motivation to solve a real-life fractional programming problem can provide the basis for a new approach in a new context that has an added value of its own, even outside the given application area. We describe the main characteristics of the DSS, the necessity to develop a non-iterative solution procedure and demonstrate both the effectiveness and efficiency of the proposed approach from practical data sets.
