Energy performance evaluation of OECD countries using Bayesian stochastic frontier analysis and Bayesian network classifiers

More recently a large amount of interest has been devoted to the use of Bayesian methods for deriving parameter estimates of the stochastic frontier analysis. Bayesian stochastic frontier analysis (BSFA) seems to be a useful method to assess the efficiency in energy sector. However, BSFA results do not expose the multiple relationships between input and output variables and energy efficiency. This study proposes a framework to make inferences about BSFA efficiencies, recognizing the underlying relationships between variables and efficiency, using Bayesian network (BN) approach. BN classifiers are proposed as a method to analyze the results obtained from BSFA.

Two graphical displays for the detection of potentially influential subsets in regression

In the context of the general linear model Y=Xβ+ε, the matrix P_z =Z(Z^TZ)^?1 Z^T , where Z=(X: Y), plays an important role in determining least squares results. In this article we propose two graphical displays for the off-diagonal as well as the diagonal elements of P_Z . The two graphs are based on simple ideas and are useful in the detection of potentially influential subsets of observations in regression. Since P_Z is invariant with respect to permutations of the columns of Z, an added advantage of these graphs is that they can be used to detect outliers in multivariate data where the rows of Z are usually regarded as a random sample from a multivariate population. We also suggest two calibration points, one for the diagonal elements of P_Z and the other for the off-diagonal elements. The advantage of these calibration points is that they take into consideration the variability of the off-diagonal as well as the diagonal elements of P_Z . They also do not suffer from masking.     

The Intervening Role of Innovative Climate: A Study of Middle Managers in Manufacturing Organizations in Iran

Based on a developed model, this study deals with an investigation on whether innovative climate is a variable that moderates the relationship among middle managers' technological innovation and organizational factors such as structure, strategic posture, and environment. We used path analysis framework to study this relationship. The respondents (N=158, n=96) were all the managers of large or medium manufacturing companies with headquarters in the province of Tehran in Iran. The study found that innovative climate has an intervening role in the relationship among organizational structure, strategic posture and environment, and middle managers' technological innovation. The results have implications for the executive and human resource management practices.     

Chaos and Transformation Theories: A Theoretical Analysis with Implications for Organization Theory and Public Management

Chaos and transformation theories have emerged as new currencies in social sciences in general and in systems design and management, and in futuristic studies in particular. This article analyzes chaos and transformation theories in historical and contemporary perspectives, their contributions to social science in general, and organization theory and public management in particular. The notions of chaos and order, change and continuity, and uncertainty and certainty are analyzed along with the growing realization of complexity and non-linear dynamic features of modern organizations and the hard reality of a constant necessity to acquire new knowledge and learn to manage organizations with flexibility and innovation. Finally, the article addresses some of the limitations of chaos theory and outlines a number of implications for organization theory and public management in the age of globalization.     

A Psychological Study of the Inverse Relationship Between Perceived Risk and Perceived Benefit

Judgments of risk and judgments of benefit have been found to be inversely related. Activities or technologies that are judged high in risk tend to be judged low in benefit, and vice versa. In the present study, we examine this inverse relationship in detail, using two measures of relationship between risk and benefit. We find that the inverse relationship is robust and indicative of a confounding of risk and benefit in people's minds. This confounding is linked to a person's overall evaluation of an activity or technology. Theoretical and practical implications of this risk-benefit confounding are discussed.     

基于智力资本的创业投资企业的价值分析

基于智力资本在知识型企业中的重要作用,本文将其引入创业投资企业的价值分析中,利用柯布-道格拉斯函数构建分离智力资本价值的模型,再结合创业投资企业的账面价值根据公式市场价值=账面价值 智力资本价值,计算出企业的市场价值,通过算例证实了该模型的可行性,并得出结论投资者在选择创业投资企业的时候不能仅看创业企业项目,还要注意企业本身的智力资本的价值,这是决定创业投资企业价值的关键环节.     

Monte Carlo studies of some adaptive robust procedures for location

One linear and two nonlinear adaptive robust procedures have been developed in which preliminary statistics, based on tail lengths, attempt to identify distributions from which the samples arise so that a suitable robust estimator based on trimmed means can be used to estimate the location parameter. The efficiencies of the estimators based on the three proposed adaptive robust procedures have been obtained using Monte Carlo methods involving eight distributions and these efficiencies are compared with the efficiencies of nineteen other robust estimators.     

贵州山区村寨生态经济发展模式初探

贵州作为一个多山区的省份,农村比例较高,山区村寨经济发展比较缓慢,事关“贵州崛起”的大局.在科学发展语境下,在“工业强省、城镇化带动”的战略导引下,贵州山区村寨如何在保“乡土”的基础上谋发展值得进一步深思.贵州山区村寨有着自身的比较优势,我们要在“后发效应”中将山区村寨的生态性、乡土性、民族性等元素结合起来,并进一步适当在农耕社会事实中融入现代市场意识,从而建构起“人与自然和谐共生”的生态经济发展模式.     

中国特色社会主义民主政治探析

政治现代化的核心是政治民主化。从对中西方民主基础理念和原则的对比出发,可以看到西方政治民主化的主要理论基础是自由主义与理性主义,原则是体现和追求个性的差异; 相反,中国的民主是建立在人人真正平等基础上的。民主集中制的本质在于追求根本利益一致基础上的“最大公约数”。今天的错误观点之一是以为西方的民主从原则到形式都是具有普遍意义的唯一。中国在民主化发展过程中从自己的历史传统和现实环境特点出发,正在探索出属于自己的道路和模式。
