Facets of narcissism and leadership: A tale of Dr. Jekyll and Mr. Hyde?

Research on narcissism continues to develop at a rapid pace. Yet, researchers from different disciplines are still divided over whether narcissists are good versus bad leaders. On the one hand, narcissists' bright qualities (e.g., charisma) are associated with positive outcomes at different levels of analysis from subordinates, to peers, and the organization as a whole. On the other hand, however, narcissists' dark qualities (e.g., entitlement) are associated with a number of counterproductive work behaviors, causing organizations to falter. The present article adds to and extends the traditional good-versus-bad debate about narcissistic leadership and pursues three goals: (a) to critically review the literature on narcissistic leaders and their behaviors in the workplace, (b) to provide tangible recommendations for how to best assess, select, and develop narcissistic leaders, and (c) to highlight future directions and ongoing challenges ahead in the field of narcissistic leadership.

Bankruptcy prediction for small- and medium-sized companies using severely imbalanced datasets

Bankruptcy prediction is still important topic receiving notable attention. Information about an imminent bankruptcy threat is a crucial aspect of the decision-making process of managers, financial institutions, and government agencies. In this paper, we utilize a newly acquired dataset comprising financial parameters derived from the annual reports of small- and medium-sized companies. The data, which reveal the true ratio between bankrupt and non-bankrupt companies, are severely imbalanced and only contain a small fraction of bankrupt companies. Our solution to overcome this challenging scenario of imbalanced learning was to adopt three one-class classification methods: a least-squares approach to anomaly detection, an isolation forest, and one-class support vector machines for comparison with conventional support vector machines. We provide a comprehensive analysis of the financial attributes and identify those that are most relevant to bankruptcy prediction. The highest prediction performance in terms of the geometric mean score is 91%. The results are validated on two datasets from the manufacturing and construction industries.

“侧袋存放”机制在基金估值中的应用研究

对因突发事件临时停牌的股票和长期停牌的股票进行估值，可以借鉴国外对冲基金经常采用的“侧袋存放”机制。在公募基金行业中采取按允许赎回不允许申购、同时允许申购和赎回两种模式，具体实施机制各不相同。实施“侧袋存放”机制在基金持有人利益、IT系统支持、信息披露、费用计提等方面存在的一些难点。

Value co-creation and employee service behaviours: The moderating role of trust in employee - hotel relationship

Value co-creation (VC) is generally considered as having mutually beneficial implications for all actors involved. Nonetheless, emerging evidence on value co-destruction and its consequences on the wellbeing of co-creating actors implies that narrowing down on specific fallouts of this process is needed for managerial interventions. This paper contributes to the value-co-creation literature by exploring the relationship between customer participation in VC on some difficult to detect employee service behaviors: workaholism and fear-based silence. The extent to which employee trust (TRS) in employee – hotel relationship moderates these relations is assessed. While the findings from 422 frontline employee-customer data within luxury hotels in Ghana support a negative effect of VC on fear-based silence and workaholism, TRS buffered these effects. We recommend that VC in service failure and recovery be approached with tact, compassion, and forgiveness.
