带野性的白野猪

白野猪是养殖户们用引进的特种野公猪和大三元母猪杂交生出的白猪或花白猪。白野猪的体型比特种野猪要略大一些，比家猪要略小一些。这种带野性的白猪与野猪相比生长快、产崽率高，但要养一年以上才能出栏，比家猪出栏时间长了一倍多。

工作绩效结构研究综述

作为在西方组织心理学领域被研究了百年的概念,工作绩效已不是一个新的研究议题,然而近些年,随着国外关于工作绩效以及战略性绩效研究的兴起,工作绩效结构问题又成为研究的热点。国内外学者在传统的绩效结构基础上,构建了不同的绩效结构框架,或者对于绩效结构的拓展做出了进一步的研究,本文结合国内外工作绩效结构的研究进展,进一步澄清工作绩效的结构问题。     

绩效考核问题探讨

绩效考核是提高绩效的重要工具。绩效考核是晋升、奖励和培训的依据。然而在现实中,很多单位的绩效考核都成了"走过场",在考核的过程中没有规范进行,从而没有把绩效考核的作用发挥出来。因此,需要对我国企事业单位的绩效考核工作进行分析、并设定科学的绩效考核体系。

Dimensions of small business performance from the owner-manager's perspective: a re-conceptualization and empirical validation

Owner-managers make decisions and manage their firm as governed by the manner in which they conceptualize or ‘conceive’ performance for themselves and their firm, rather than being governed by researchers' and experts' conceptualizations of small business performance. On the basis of survey data obtained from 433 Canadian small businesses, this study aims at a deeper understanding of what owner-managers conceive performance to be, and to what extent this conception is determined by their objectives and social influences.     

HR practices and New Zealand firm performance: what matters and who does it?

We examine the impact of human resource practices, especially those considered as parts of high performance work systems, on firm performance. The analysis is unique in using data from an economy-wide official survey to determine whether firms that adopt high performance HR practices perform better than their rivals. We find that adoption of a suite of high performance practices (and adoption of specific practices pertaining to staff training and performance pay) has a causal impact on firm outcomes. The strength of the relationships differs by firm size and age. Firms that adopt high performance practices are predominantly young and in high-tech related sectors.

Corporate performance patterns of Canadian listed firms: Balancing financial and corporate social responsibility outcomes

Based on stakeholder theory and considering the conflicting performance interests of a wide range of stakeholders, this research investigates corporate performance patterns using a cluster analysis of financial, social, and environmental performance dimensions. An analysis of a Canadian sample of 771 company-year observations for the period 2014–2018 reveals three types of corporate performance: financially focused performance, balanced performance, and corporate social responsibility (CSR)-focused performance. Firms in the largest cluster, financially focused performance, deliver poor sustainable performance and prioritize financial performance over social and environmental performance. The CSR-focused performance cluster scores low for financial performance and high for environmental and social performance. The balanced-performance cluster also has higher levels of sustainable performance but is the smallest cluster, accounting for a quarter of the sample. Overall, this study presents a portrait of corporate performance balancing financial and CSR objectives and the evolution of this activity over the research period.

The effect of individual HR domains on financial performance: evidence from Belgian small businesses

The contribution of this study, which assesses the influence of HRM on financial performance, is fourfold. (1) We assess the relative contribution of different HR domains to organizational performance. By controlling for the overall HRM intensity in all analyses we try to meet one of the most striking shortcomings of ‘single HR practice research’, namely the neglect of the potential simultaneity that might exist with other HR practices. (2) By studying small Belgian companies, we focus on the importance of HRM for small business management. (3) Relying on bankruptcy prediction models, we optimize the conceptualization of financial performance. (4) Using structural equation modelling, we try to capture the mediating effect of operational performance on the relationship between HRM and financial performance. The analyses indicate mixed results for different HR domains with regard to their impact on operational and financial performance.     

The anatomy of performance appraisals in Germany

We investigate the use of performance appraisal (PA) in German firms. First, we derive hypotheses on individual and job-based determinants of PA usage. Based on a representative German data set on individual employees, we test these hypotheses and also explore the impact of PA on performance pay and further career prospects. The results include that PA is positively linked to an individual's willingness to take risks. The performance of older employees and woman is evaluated less often. Furthermore, larger firms evaluate the performance of their employees more. We find evidence for a non-monotonic relation between the hierarchical level and usage of performance appraisal: The performance of employees with very high or very low responsibilities is assessed less often.
