浅析人力资源会计的计量问题

进入知识经济时代,人作为一种资源越来越受到重视。尤其在我国,作为一个人口大国,人力资源是一项非常重要的资源,而人力资源会计尚未得到广泛应用的原因主要在于"人力资源会计计量"的困难。就人力资源会计计量方面的问题作了一些比较探讨。     

我国对外技术依存度的测算及浅析

建设创新型国家成为国家的战略目标,而对外技术依存度的高低成为衡量创新型国家的一个重要指标。针对当前对外技术依存度算法的不足,提出一种全新的测算方法,从技术依存度的内涵出发系统地构造衡量指标和计量模型,运用因子分析方法对我国对外技术依存度进行了测算,并简析其原因。结果显示,中国的对外技术依存度在快速提高,并处于很高的水平,表明我国的技术对外依赖程度非常高,经济技术发展受制于人,我国亟需加强自主创新。     

Measurement of patient-reported outcomes. 1: The search for the Holy Grail

Abstract

Patient-reported outcome measures (PROMs) are used to collect information directly from patients. They may cover several different types of outcomes ranging from symptoms, functioning, utility, satisfaction, through to quality-of-life (QoL). They generally consist of self-completed questionnaires that can be administered by means of hard copies or in a range of electronic formats. PROMs vary considerably in terms of the constructs they assess, the care with which they are developed, and their scientific quality. However, none of the PROMs available approach the quality of measurement achieved by measures/instruments used in physics. PROs are examples of latent variables. These are not directly observable, but can be inferred from, for example, responses to a questionnaire. The only measure of a latent variable that approaches the quality of measurement achieved by the physical sciences is the Lexile Framework for Reading. This framework is based on a construct theory that grew out of an analysis of several available reading measures. A specification equation was generated that was able to link the construct theory to scores obtained with the Lexile measure. A fundamental requirement of this quality of measurement is that the data collected with the model fit Rasch Measurement Theory (RMT). It is argued that PROM developers should aspire to match this level of measurement sophistication if their instruments are to provide valid insights into the impacts of disease and its treatment.     

When profession trumps potential: The moderating role of professional identification in employees’ reactions to talent management

Abstract

This study aimed to investigate the role that a professionalized context plays in shaping employee reactions to talent management decisions. We examined the mediating role of felt obligation in the relationship between talent ratings and organizational citizenship behavior. Further, the study tested whether professional identification moderates the relationship between talent ratings and felt obligation towards the organization. Five hundred and ninety-eight teachers that had recently received ratings of their talent status responded to a survey questionnaire. Felt obligation mediated the relationship between talent ratings and organizational citizenship behavior. Furthermore, professional identification moderated the relationship between ratings of potential and felt obligation in such a way that the relationship was strongest for the teachers expressing the lowest professional identification. At high levels of professional identification, the relationship was not significant. These results indicate that conventional talent management might be less effective for increasing favorable attitudes and behaviors among employees in highly professionalized contexts, such as the education sector.

Building internal business scenarios based on real data from a performance measurement system

This paper presents a new methodology to build internal business scenarios from the data gathered by some key performance indicators (KPIs) defined within a performance measurement system. The application of the principal components analysis technique leads to the identification of latent relationships between KPIs that underlies some important business aspects. Further, this methodology allows to represent not only the temporal evolution of the organisation as a function of these business aspects but also the definition and determination of internal business scenarios, being therefore the source of meaningful managerial information. At the end of the paper, results of a practical application are presented and discussed, as well as their importance for the organisation from a decision making point of view.     

Comparing linear and nonlinear forecasts for stock returns

We compare the out-of-sample performance of monthly returns forecasts for two indices, namely the Dow Jones (DJ) and the Financial Times (FT) indices. A linear and a nonlinear artificial neural network (ANN) model are used to generate the out-of-sample competing forecasts for monthly returns. Stationary transformations of dividends and trading volume are considered as fundamental explanatory variables in the linear model and the input variables in the ANN model. The comparison of out-of-sample forecasts is done on the basis of forecast accuracy, using the Diebold and Mariano test [J. Bus. Econ. Stat. 13 (1995) 253.], and forecast encompassing, using the Clements and Hendry approach [J. Forecast. 5 (1998) 559.]. The results suggest that the out-of-sample ANN forecasts are significantly more accurate than linear forecasts of both indices. Furthermore, the ANN forecasts can explain the forecast errors of the linear model for both indices, while the linear model cannot explain the forecast errors of the ANN in either of the two indices. Overall, the results indicate that the inclusion of nonlinear terms in the relation between stock returns and fundamentals is important in out-of-sample forecasting. This conclusion is consistent with the view that the relation between stock returns and fundamentals is nonlinear.     

成本计量模式与企业成本控制机制研究

成本计量模式存在着制造环节、价值链与商业模式三个视角的划分,它们反映了不同成本效益对称情形,三者间具有层次演进性。从成本与利润的关系看,企业内部就是成本计量,利润则是市场角度的成本补偿计量,企业机制就可以视为在有意义的领域做出独特或某种与众不同的贡献而进行的成本流程安排。企业健康成本结构应该是一个开放的以接纳先进价值观的信息综合体。企业要获得可持续竞争力就必须树立科学的成本控制观念。     

基于网络处理器IXP2400的组播包高速转发技术

传统的IP报文的组播技术,由于在处理过程中需要把整个报文的内容报文复制多份,因此处理器需要对缓存报文的外部存储空间进行多次I/O操作,这严重制约了当前处理器,特别是网络处理器的高速报文处理能力,转发效率不高.为此,提出了一种新的技术--"零拷贝"转发技术.该技术只修改报文头,报文体不复制,减少了大量的I/O操作,提高了转发效率.
