Feature selection methods involving support vector machines for prediction of insolvency in non‐life insurance companies

We propose two novel approaches for feature selection and ranking tasks based on simulated annealing (SA) and Walsh analysis, which use a support vector machine as an underlying classifier. These approaches are inspired by one of the key problems in the insurance sector: predicting the insolvency of a non‐life insurance company. This prediction is based on accounting ratios, which measure the health of the companies. The approaches proposed provide a set of ratios (the SA approach) and a ranking of the ratios (the Walsh analysis ranking) that would allow a decision about the financial state of each company studied. The proposed feature selection methods are applied to the prediction the insolvency of several Spanish non‐life insurance companies, yielding state‐of‐the‐art results in the tests performed.

Non-monetary sales promotion effects on credit cards

This study fills an important gap in the literature by exploring the effects of the attractiveness of a non-monetary promotion with premiums on credit card purchase intention and brand selection. Two experimental studies involving 386 undergraduates were done. Non-monetary sales promotions with attractive premiums have a positive influence on the credit card purchase intention, compared to non-monetary sales promotions with unattractive premiums. On brand choice, non-monetary sales promotions with attractive premiums increase the likelihood of brand choice promoted. Premiums attractiveness is an important variable in the evaluation of a promotional offer that aims to increase the intention purchase and motivate the selection of brand. This study helps managers in choosing the types of premiums that are valued by consumers in a promotion. Most of the studies explore monetary promotions, while this study contributes to literature by exploring the gap about the effects of non-monetary sales promotions on purchase intention and brand selection, especially in the bank services environment.

Content analysis research method with Nvivo-6 software in a PhD thesis: an approach to the long-term psychological effects on Chilean ex-prisoners survivors of experiences of torture and imprisonment

The aim of this paper is to review the usefulness of the software CAQDAS QSR—Nvivo-6 in a PhD. Thesis, which consisted of finding the long-term psychological effects of experiences of imprisonment and torture for political reasons in their Chilean survivors. For this research, it was created and administered an in-depth interview to 60 survivors, from which outcome was 9900 paragraphs, coded into 784 categories. The software QSR Nvivo-6 threw a report of frequencies, which were compared quantitatively using Pearson’s χ ² square test and cluster analysis. We conclude that the software facilitates the development of qualitative thematic content analysis, simplifying the coding, analysis and display of data. In Addition, it is very useful when working with large quantities of information, promoting the reliability and validity of studies. However, other aspects are also required to ensure the rigor of a qualitative study.     

Mining History of Gamification Towards Finding Expertise in Question and Answering Communities: Experience and Practice with Stack Exchange

Recently, an online Q&A tool has become an essential part of individual communities and organizations of experts on specific topics. Using the answers to questions about specific topics will help such communities work more efficiently in their fields. Currently, Q&A online communities are adopting gamification to engage users by granting awards to successful users. In this paper, we investigate how to mine award achievement histories to find expertise. We propose the use of sequence analysis and clustering techniques. Specifically, we study the history of Stack Exchange, a large Q&A community that employs gamification. To the best of our knowledge, this is the first study of using award achievement history to find expertise in Q&A communities.     

Corporate Social Responsibility,Product Differentiation Strategy and Export Performance

This article examines why an organization might wish to manage workplace romance, and describes a number of alternative approaches to managing dating. At first sight the ethics of dating bans balances the need to protect female employees from harassment against employee rights to privacy and freedom of association – a rights versus rights issue. However, dating bans seem not to be directed at protecting female employees from harm, but rather protect employers from sexual harassment liability claims – an employer self-interest versus employee rights issue. This article advocates a consequentialist approach to the problem, via the factoring in of other harms caused by prohibiting workplace romance. Given that most workplace romances end up in marriage or long-term partnerships, a ban on workplace romance is argued to be antisocial. The incidence of sexual harassment is very low in comparison to the number of long-term relationships initiated in the workplace. This article concludes by citing examples of firms that encourage romance, showing that is feasible to manage any resulting problems within these firms’ existing conflict of interest and sexual harassment rules.     

Putting ethics and economic rationality together: an Aristotelian and philosophical approach

The gap between economic rationality, as embedded in utility maximization, and ethical rationality, identified with a set of rules that prescribe the right course of action, has been a challenging issue for economists, philosophers, and business ethicists. Despite the difference and the noncompetition between a scientific economic approach of economics and business ethics, and a behavioral and philosophical one, we highlight the importance of the Aristotelian concept of prudence or phronesis applied to business activity. Phronesis allows for a conceptualization of rationality that can be simultaneously applied to economics and ethics. It also allows conceiving the intrinsically ethical nature of economic rationality. This relationship requires an appropriate education and the intervention of the state.     

Influence of Affective Traits on Entrepreneur's Goals and Satisfaction

Emotions are important to an individual's behavior. However, affective elements have rarely been included in the analysis of entrepreneurs' behavior. Using a sample of 335 entrepreneurs from multiple industries of the Spanish region of Castile and León, we analyze the role of emotions in entrepreneurs' statement of goals and in their satisfaction with business performance. The results show that positive affective traits influence an entrepreneur to state broad and ambitious goals, and personal negative affective traits influence an entrepreneur to state a narrow set of goals. We also find that positive (negative) affective traits are positively (negatively) related to entrepreneur satisfaction.
