Financial distress prediction based on SVM and MDA methods: the case of Chinese listed companies

How to accurately predict financial distress is an important issue for enterprise managers, investors, creditors and supervisors. In this paper we develop SVM models (Support Vector Machine) and MDA (Multivariate Discriminant Analysis) models, using Chinese listed companies as our sample. The empirical results show that the prediction ability of SVM models outperforms the MDA models. Additionally, internal governance and external market variables, as well as macroeconomic variables are added as the predictive variables. The results indicate that these variables have theoretical and empirical linkage with the financial distress of Chinese listed companies.

Bringing Political Skill into Social Networks: Findings from a Field Study of Entrepreneurs

The authors integrate the entrepreneurship literature's sociological and behavioural perspectives and examine the processes through which entrepreneurs first build social networks and then use the network resources for enhancing venture performance. Field interviews of entrepreneurs during a six‐month period reveal that political skill is an important individual‐level factor that influences the construction and use of social networks. Theoretical and practical implications of the major findings are discussed.     

Strategic HRM in China: Configurations and competitive advantage

The strategic HR literature suggests that a firm will perform better through internal appropriate fit among HRM practices (the configuration fit) and through external appropriate fit between a firm's HRM practices and business strategy. The present study adopts a configuration approach to identify unique patterns of HR practices and business strategy that are posited to be maximally effective. The proposed relationships were empirically tested by surveying with a sample of 241 business firms in Guangzhou, South China, to find out the extent that four HR configurations could be successfully adopted in the Chinese context. The results revealed that HR configurations are significantly related to effect in predicting overall outcome performance and turnover, but not significantly related to effect on sales growth and profit growth rates. Research findings showed not only competitive strategies are significantly related to effect on HR configurations. The results also showed significant interaction effects between HR configurations and business strategy in their effect on profit and sales growth. These results further extended support for a contingency perspective in strategic HRM to the Chinese context, with significant practical implications for managing HRM in China. © 2008 Wiley Periodicals, Inc.     

人口普查中遗漏人口数的估计

研究目标:用完整遗漏估计量替代目前使用的未匹配遗漏估计量、逆记录检查遗漏估计量和平衡推算遗漏估计量。研究方法:采取文献解读、成果借鉴和移植及实地调查相结合的方法,研究完整遗漏估计量及其方差估计。研究发现:人口普查遗漏估计不只是要提供遗漏估计值,还要揭示遗漏的原因及其遗漏者的特征;构造普查遗漏估计量,既要包括登记在事后计数调查人口名单而未登记在普查名单的单重遗漏人口,还要包括同时遗漏于这两项调查名单的双重遗漏人口。研究创新:提出完整遗漏估计量。研究价值:完整遗漏估计量有望应用于中国2030年普查遗漏估计,开创世界人口普查遗漏估计应用完整遗漏估计量的先河。     

Australian consumer attitudes to health claim – food product compatibility for functional foods

This study with Australian consumers investigated how appealing different health claims combined with particular food carriers were to Australian consumers, and compared the results of a similar study with Dutch consumers. 149 shoppers considered up to 30 different food concepts, rating how ‘attractive’, ‘believable’, and ‘new and different’ they found each concept and their ‘intention to try’. Each variable was significantly related to intention to try (p < 0.001) and together explained 56% of the intention score. Claims and carriers independently had a significant effect on ratings of attractiveness and intention to try but, unlike the Dutch study, the carrier was a more important predictor of intention to purchase than the claim. Implications for regulation of health claims for food are discussed.     

New evidence of regional income divergence in post-reform Russia

This article investigates regional income convergence in Russia during 2000–2008. We test the hypothesis in which income divergence across regions of the country should give place to income convergence as the country moves toward free market economy with strong market institutions. The study contributes to the existing literature by using the exponential smooth autoregressive Augmented Dickey–Fuller (ADF) unit root test in a panel setup, a novel econometric technique, which encompasses cross sectional dependence. Results show strong evidence of on-going regional income divergence in post-reform period.     

Community college economics instruction: Results from a National Science Foundation Project

The principal investigator of a National Science Foundation project, “Economics at Community Colleges,” surveyed community college economics faculty and organized workshops, webinars, and regional meetings to address community college faculty isolation from new ideas in economics and economics instruction. Survey results, combined with National Study of Postsecondary Faculty data, help fill a lacuna in information about community college faculty. A key finding is the reliance in community college economic instruction on part-time faculty, including many who do not hold a graduate degree in economics. The project's webinars reached the most community college faculty, while the workshops were most effective in improving economics instruction. Areas for future research are identified.
