学科难度与专业劳动复杂程度模糊谱系的建构--以中国大学本科教育为例

本文综合运用心理学、哲学、经济学、教育学的成果,以中国大学本科教育为例,对劳动复杂程度的模糊度量问题进行了探讨.认为专业劳动的复杂度由专业学习难度决定,专业学习难度由其横断学科和经验知识含量决定,而这些含量由专家系统提供的主要课程设置来体现.并由此建立了专业学科难度模糊谱系和相应的专业劳动复杂度模糊谱系.     

No Country Left Behind? Performance Standards and Accountability in US Foreign Assistance

The accountability movement in public policy hails a new programme for US foreign assistance – the Millennium Challenge Account established in 2004 with the aim of ‘picking winners’ for grants among developing countries based on their demonstrated quality of governance. This article uses the MCA's own rating system to dispute its claim to know in advance which countries are best positioned to meet major development goals. High governance scores alone bear little or no relationship to growth in national income or decline in poverty. Attempting to measure public‐policy performance limits the range of choice available to policy‐makers, and may inadvertently limit true performance.     

Integrating psychometric and cultural theory approaches to formulate an alternative measure of risk perception

Psychometric and cultural theory are key approaches used to explain risk perceptions. However, both approaches explain only 20 and 5–10% of the variance of risk perceptions, respectively. Through advances in social psychology, terror management theory revealed that certain survey questions used in the psychometric approach primed thoughts of death. Such unintentional priming evoked defense mechanisms that would subconsciously activate participants’ cultural biases and values when answering some questions but not others. There are two implications: one, psychometric theorists need to modify their questionnaires to reduce the incidence of priming thoughts of death; and two, integrating the psychometric and cultural theory approaches may potentially explain a higher amount of variance in risk perceptions. Specifically, attitudes (psychometric approach), demographics, affect and past behavior collectively influence cultural biases, which in turn exert an effect on risk perception. However, such a model calls for an appropriate measure of the dynamic nature of cultural biases that current attitudinal measures fall short of. Drawing from methodology within industrial/organizational psychology, the Situational Judgment Test (SJT) is proposed as an alternative measure for risk perception. Steps to designing an SJT are outlined and followed through to culminate in a 10-item SJT that measures cultural biases.     

Unbiased estimation of a nonlinear function a normal mean with application to measurement err oorf models

Let W be a normal random variable with mean μand known variance σ². Conditions on the function f(·) are given under which there exists an unbiased estimator, f(W), of f(μ) for all real μ. In particular it is shown that f(·) must be an entire function over the complex plane. Infinite series solutions for F(·) are obtained which are shown to be valid under growth conditions of the derivatives, f^k( ·), of f(·). Approximate solutions are given for the cases in which no exact solution exists. The theory is applied to nonlinear measurement-error models as a means of finding unbiased score functions when measurement error is normally distributed. Relative efficiencies comparing the proposed method to the use of conditional scores (Stefanski and Carroll, 1987) are given for the Poisson regression model with canonical link.     

An application of the integrated AHP-PGP model for performance measurement of supply chain management

The performance measurement problem has gained great attention in business and operations management literature. The first objective of this study is to determine the required performance measures and to develop a model for performance evaluation, based on these selected measures using analytical hierarchy process (AHP) methodology. The second objective is to explain how an integrated AHP-PGP (pre-emptive goal programming) model can be used in performance measurement while optimising the overall performance. An integration of AHP and multi-objective PGP is used to consider both quantitative and qualitative performance measures in optimising the overall performance of the system. The integrated model is presented with a real-world application using source data provided by a survey conducted in India. Findings demonstrate that the integrated AHP-PGP model can be useful to all supply chain industries in their day-to-day performance measurement decisions.     

Measuring Sexual Prejudice Against Gay Men and Lesbian Women: Development of the Sexual Prejudice Scale (SPS)

The presence of bias against gay men and lesbian women remains an ongoing issue, and accurate measurement is essential to targeted intervention. A validation study of a new instrument, the Sexual Prejudice Scale, is reported. Students (N = 851) from 4 different universities participated in this study. An exploratory factor analysis and confirmatory factor analysis were conducted, and results of these analyses indicated a 3-factor solution (affective – valuation, stereotyping, and social equality beliefs) for each of the sex-specific scales. Evidence of validity and the results of the reliability analysis are reported. Implications for future research are discussed.     

电位差计灵敏度与工作电源电压关系的探讨

用直流电位差计对电动势(或电压)进行测量时,测量结果是经过两次比较一“校准工作电流”和“测量”才能得到的,因此装置的灵敏度是影响测量结果精度的重要因素,而电位差计工作电源与其灵敏度有复杂的关系.从校准和测量两方面研究电位差计灵敏度与其工作电源电压的关系,对正确使用电位差计,减少实验误差具有重要的指导作用.

Target Specificity of Subjective Relationship Measures: Understanding the Determination of Item Variance

The present study was conducted to test the ability of two subscales from the Friendship Quality Questionnaire (FQQ; Parker & Asher, 1993 ) to discriminate between different target friendships. This was done by testing for mean differences between targets, and by using both exploratory and confirmatory factor analyses to examine the factor structures for these measures when the responses for different targets were considered together. Participants were 293 Italian middle‐school students. Both subscales (Validation and Caring, and Conflict and Betrayal) showed mean differences between the best friend and the second and third best friends, but only the validation and caring subscale demonstrated differences between the second and third best friends. Factor analyses showed that for both subscales some items were able to discriminate between friends whereas others were not. Confirmatory factor analyses demonstrated the existence of target‐specific factors, as well as a common ‘individual differences’ factor. Practical and theoretical issues regarding the different sources of item variance are discussed.     

团队反省理论研究述评

团队反省(team reflexivity)的概念构思基于对创新任务团队作业过程的考察而提出.有关团队反省的维度划分及测量尚未达成共识.已有研究中涉及的影响团队反省的前因可归为个体特征、任务特征和团队特征三大类;而团队反省的结果主要表现为对团队效能、效率以及创新的影响.此外,团队反省还在结果依赖性、意见不一致及其在与团队产出变量间的作用关系中起调节作用.文章在对该构思相关研究进行梳理的基础上,对其未来的发展趋势进行了初步探讨.
