企业绩效考核有效性研究

企业绩效考核常被认为是企业人力资源管理活动中最重要的内容。近年来,国内外有关绩效考核的理论研究取得了很大进展。企业绩效考核有效性的影响因素有:绩效考核定位模糊,存在主观性,缺乏沟通与反馈,指标缺乏科学性等。企业绩效考核取得良好效果的对策是:明确绩效考核目标,完善考核指标,加强对考核者的教育和培训,建立反馈控制系统等。     

发展大企业集团优化中国乳业市场结构

一个国家的产业竞争力受多种因素影响,其中市场结构是关键因素。目前我国乳业市场存在的问题主要是市场集中度低、企业规模小、进入壁垒低;深层次原因是市场结构不合理,导致企业经营绩效低下。因此,从优化市场结构入手,发展大企业集团对规范企业行为和提高市场绩效具有重要的实践意义。     

管理有效性及其在企业管理中的地位

管理有效性是指剔除客观基础条件优劣的影响,真正反映由于管理者主观努力而产生经济效益的管理活动的行为特性.在企业管理中,管理有效性是管理科学的重要内容和基本原则,是选择管理模式的根本标准,是管理制度兴衰的显著标志,是制约管理绩效和企业效益的重要原因.     

CeO2／蛇纹石体系对饮用水的脱氟行为研究

本文探讨了利用均相沉淀法制备的二氧化铈的脱氟行为,并利用蛇纹石作为载体,对CeO2/蛇纹石体系的除氟行为及最佳条件进行了进一步的研究,结果表明：均相沉淀法得到的二氧化铈除氟效率高,除氟容量可达11.76mg/g。以二氧化铈;蛇纹石为1：10的混合体系的除氟容量大大高于其他方法处理过的蛇纹石体系,其附近氟容量达到0.568mg/g。     

Practical procedures to deal with common support problems in matching estimation

This paper assesses the performance of common estimators adjusting for differences in covariates, such as matching and regression, when faced with the so-called common support problems. It also shows how different procedures suggested in the literature affect the properties of such estimators. Based on an empirical Monte Carlo simulation design, a lack of common support is found to increase the root-mean-squared error of all investigated parametric and semiparametric estimators. Dropping observations that are off support usually improves their performance, although the magnitude of the improvement depends on the particular method used.     

Estimating ordered quantiles of two exponential populations with a common minimum guarantee time

The problem of estimating ordered quantiles of two exponential populations is considered, assuming equality of location parameters (minimum guarantee times), using the quadratic loss function. Under order restrictions, we propose new estimators which are the isotonized version of the MLEs, call it, restricted MLE. A sufficient condition for improving equivariant estimators is derived under order restrictions on the quantiles. Consequently, estimators improving upon the old estimators have been derived. A detailed numerical study has been done to evaluate the performance of proposed estimators using the Monte-Carlo simulation method and recommendations have been made for the use of the estimators.     

The globalization of local indexicalities through music: African-American English and the blues

This article reports on a sociolinguistic study into the prevalence of African-American English (AAE) features in the lyrical language use of blues artists, relying on data from different social and national backgrounds and time periods. It adopts a variationist linguistic methodological approach to examine the prevalence of five AAE forms in live-performed blues music: /aɪ/ monophthongization, post-consonantal word-final /t/ deletion, post-consonantal word-final /d/ deletion, alveolar nasal /n/ in < ing > ultimas, and post-vocalic word-final /r/ deletion. Mixed effects logistic regression analysis applied to a corpus of 80 performances finds no statistically significant association between national/ethnic background and variant use, and indicates that blues artists, from different eras and nationalities, are highly probable to realize the AAE variant of the analyzed variables, regardless of their sociocultural background. By building on early scholarly work on language and music, existing studies considering the use of AAE by non-members of the African-American community, and current theorizing on authenticity, style, and indexicality, this study hence provides tentative support for the existence of a standard blues singing style, which involves performers using AAE forms as a stylistic-linguistic strategy to index artistic authenticity.     

Strategic corporate sustainability performance of Chinese state-owned listed firms: A meta-frontier generalized directional distance function approach

Although sustainability recently became a key factor in social science, little progress has been made toward improving the measurement of sustainability performance. This paper proposes composite corporate sustainability performance indicators using a meta-frontier generalized directional distance function. This advanced approach can measure the efficiency of corporate social responsibility activities by benchmarking, while simultaneously considering industrial heterogeneities, using the meta-frontier approach. First, we propose the concept of a meta-frontier generalized directional distance function. Second, several standardized composite indicators related to corporate sustainability performance are developed. The meta-frontier directional distance function is estimated by solving a series of data envelopment analysis models. Chinese state-owned listed enterprises are then empirically examined using the proposed model. We find significant group heterogeneities in terms of corporate sustainability performance. We also derive some policy implications using the empirical results.     

How to Evaluate Government Performance while Building a Rule of Law Government in China*

Building a law-based government is a central element of the comprehensive framework for promoting the rule of law in China, while using evaluation to catalyze growth is in line with the incentive principle of management studies. Since China started to implement reform and opening up over thirty years ago, rule of law development and organizational evaluation have gone through several stages, each with different characteristics. Efforts to build a law-based government have met with success, but what the country now has is essentially still goal-oriented assessment. At present, this suffers from the lack of a clear goal orientation or definition of functions, an imperfect technical system and unsound motivation mechanisms, not to mention the practical problems of each government department going its own way, duplicating evaluations or being left rudderless. Drawing on a combination of value rationality and instrumental rationality and using government performance evaluation to promote the building of a law-based government not only conforms to the spirit of the rule of law and value rationality in government performance, but also strengthens the role of evaluation as an instrument for organizational management. Therefore, we need to create new evaluation theories, expand public participation, introducing diversified evaluating entities, improve technical systems, strengthen institutional buildup, and foster a performance-based culture. In addition, replacing goal-oriented assessment with performance evaluation will help the emergence of a new discipline—the performance evaluation of rule of law government, thus promoting multidisciplinary efforts to integrate and create new public administration theories in China.
