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.

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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

Systems of equations comprising cost functions and first-order derivative equations are often used to estimate characteristics of production technologies. Unfortunately, many estimated systems violate the regularity conditions implied by economic theory. Sampling theory methods can be used to impose these conditions globally, but these methods destroy the flexibility properties of most functional forms. We demonstrate how Bayesian methods can be used to maintain flexibility by imposing regularity conditions locally. The Bayesian approach is used to estimate a system of cost and share equations for the merino wool-growing sector. The effect of local imposition of monotonicity and concavity on the signs and magnitudes of elasticities is examined. 相似文献

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. 相似文献

This work presents the participation factor and the valuation of a first-generation structured product with European call options on the Eurostoxx, when the uncertainty of the yields is modeled through log-stable processes. The basic statistics of the index yields are also exposed, the α-stable parameters are estimated, and the valuation of the of the structured models is compared through the log-stable and log-Gaussian models using inputs from the bond markets; concluding that investors obtain higher yields than those of the bond market through both models, and that the differences of the yields depend on the participation factor and on the value of the index at the time of liquidation. 相似文献
