Poker is a type of gambling that has specific features, including the need to regulate one’s emotion to be successful. The aim of the present study is to assess emotion regulation, anxiety and depression in a sample of regular poker players, and to compare the results of problem and non-problem gamblers. 416 regular online poker players completed online questionnaires including sociodemographic data, measures of problem gambling (CPGI), anxiety and depression (HAD scale), and emotion regulation (ERQ). The CPGI was used to divide participants into four groups according to the intensity of their gambling practice (non-problem, low risk, moderate risk and problem gamblers). Anxiety and depression were significantly higher among severe-problem gamblers than among the other groups. Both significantly predicted problem gambling. On the other hand, there was no difference between groups in emotion regulation (cognitive reappraisal and expressive suppression), which was linked neither to problem gambling nor to anxiety and depression (except for cognitive reappraisal, which was significantly correlated to anxiety). Our results underline the links between anxiety, depression and problem gambling among poker players. If emotion regulation is involved in problem gambling among poker players, as strongly suggested by data from the literature, the emotion regulation strategies we assessed (cognitive reappraisal and expressive suppression) may not be those involved. Further studies are thus needed to investigate the involvement of other emotion regulation strategies.  相似文献

Statutory audits are only beneficial if the appropriate audit quality is both provided and perceived by the users of audited financial statements. On the one hand, Big 4 audit firms are commonly viewed as producing high quality audits. On the other hand, regulators complain about the high market share of Big 4 audit firms. In this context, it is of interest to examine the drivers of a Big 4 audit firm selection. Despite extensive prior research, there is still a lack of findings form Continental European countries and on the impact of corporate governance on auditor choice. This paper on hand is intended to fill the related research gap. Thus, our study identifies variables that determine the auditor choice of large German listed companies. Based on a sample of 432 firm-year observations for the period 2010–2014, our logistic regression analysis suggests that the corporate governance structure influences auditor choice significantly. Notably, the annual meeting frequency of the audit committee and the size of the supervisory board are positively associated with the engagement of a Big 4 audit firm. However, the meeting frequency of the supervisory board and the compliance to the German corporate governance code are negatively related to the choice of a Big 4 auditor. Additionally, the proportion of female supervisory board members does not exert a significant impact. The results remain stable when the DAX30 observations, for which statutory audits are exclusively performed by Big 4 audit firms, are excluded. The main contribution of our paper is, that it sheds light on the impact of corporate governance variables not analyzed by prior research, like supervisory board characteristics, deviations from a corporate governance code, or the female quota, in a Continental European setting, and that it mainly indicates a complementary relationship. Despite the peculiarities of the German setting, the two-tier corporate governance system and the low level of investor protection, the findings of our study are not only relevant for Germany, since many other Continental European countries are characterized by a similar environment. The study’s findings are of particular interest for regulators when addressing audit market structure problems.  相似文献

This study continues our analyses of contacting behavior in online dating (KZfSS 2/2009). As the beginning and continuation of a relationship is based on consensual decisions of both partners to interact, we concentrate on the question if and how potential partners indeed reply to contact offers. Data from online dating platforms therefore offer a unique opportunity for sociologists to study how partnerships are initiated and how they develop over time. This contribution provides four important empirical results: Firstly, it demonstrates that only 20% of all first contact offers are answered. This is a surprisingly small proportion. Secondly, it supports the hypothesis of homophily. According to this hypothesis, people with similar education, age and physical attractiveness should prefer each other and thus are more likely to form couples. Third, it shows that women still have severe problems to reply to contact offers from lower educated men, while men are already less reluctant to reply to higher educated women. Thus, the rarity of couples where women are higher educated than their partners are to a large proportion the consequence of women’s preferences rather than men’s preferences. Finally, our study does not find any support for the trade-off hypothesis, indicating that women do not exchange their physical attractiveness for men’s educational resources, and vice versa.  相似文献

One of the most important factors influencing aircraft seating comfort in economy class, is legroom. In an airline interior mock up, with the ability to adjust the seat pitch in a range of 28 inches to 43 inches, a study to investigate the influence of seat pitch on passengers' well-being was conducted. In a pre-study, aspects of subjective postural sensations and spatial perception were identified, and a questionnaire was developed. In the main study, 30 subjects rated at different seat pitch settings the spatial perception and the ability of adopting and changing sitting postures. As a result a functional relationship between overall well-being, the subjects' anthropometry and seat pitch was developed. Furthermore it was identified, that there is a maximum overall well-being at a seat pitch of 34 inches to 40 inches, depending on the passengers' anthropometry. A further enlargement of seat pitch, led to a reduction of well-being.  相似文献

The literature supports and recommends that firms be responsive to external environments for prosperity and survival. However, many firms do not seem to heed this advice when it comes to important but uncontrollable environmental forces such as population aging. We investigate firms' (non)responses to population aging, one of the grand challenges of our time. While theoretical explanations for firms' responses to external environments abound, surprisingly, we lack concrete empirical evidence about why some companies do not respond to population aging while others do. Building on the cognition–response framework and utilizing a sample of 545 Japanese corporations, we investigate the magnitude and extent of organizations' corporate-level responses to population aging in Japan, the world's most aged society. While controlling for the firms' resource dependence and slack resources, we find robust, positive effects of perceived state certainty on organizational responses. Specifically, we find that perceived state certainty takes both direct and indirect routes (Daft and Weick 1984) to increasing firm response to population aging. We also find that firms' self-perceived controllability has a direct effect on firm response. Most intriguingly, the organization's ambivalence toward the implications of population aging on their business does not directly reduce firm response. Instead, it is found to be a quasi-moderator that interacts with perceived state certainty and negatively affects the responses to population aging. Ambivalence is an important factor that has been largely overlooked and warrants more research attention to address not only this particular grand challenge but also others (e.g., climate change).  相似文献

At the core of the German system of welfare provision stand social insurance schemes whose central role contributes to Germany being labelled a social insurance state. In recent decades, Germany has been experiencing major social policy reforms that are often evaluated as paradigm changes. These changes have been reflected in analyses that sometimes even questioned common classifications of the German welfare state. The article sheds light on recent developments that have affected the German system of social insurance. It focuses on four aspects of social insurance: benefits, financing, governance, and coverage. Although confirming many earlier analyses of reforms in detail and sharing assessments of changes such as retrenchment and marketization, the article nevertheless stresses that social insurance remains structurally intact and that the work–welfare nexus underlying welfare provision has been reinterpreted but not surrendered.  相似文献

We consider two players' choice about the formation of an alliance ahead of conflict in a framework with incomplete information about the strength of the potential ally. When deciding on alliance formation, players anticipate the self‐selection of other players and the informational value of own and other players' choices. In the absence of these signaling effects, strong players have an incentive to stand alone, which leads to a separating equilibrium. This separating equilibrium can be destabilized by deception incentives if beliefs are updated on the basis of endogenous alliance formation choices. Weak players may find it attractive to appear strong in order to deter competitors from positive effort choices. Strong players may find it attractive to appear weak in order to give their competitors a false sense of security and then beat them with little effort. Moreover, appearing weak allows players to free‐ride when alliances are formed. (JEL D72, D74)  相似文献

Noting that many economic variables display occasional shifts in their second order moments, we investigate the performance of homogenous panel unit root tests in the presence of permanent volatility shifts. It is shown that in this case the test statistic proposed by Herwartz and Siedenburg (2008 Herwartz, H., Siedenburg, F. (2008). Homogenous panel unit root tests under cross-sectional dependence: Finite sample modifications and the wild bootstrap. Computational Statistics and Data Analysis 53(1):137150.[Crossref], [Web of Science ®] [Google Scholar]) is asymptotically standard Gaussian. By means of a simulation study we illustrate the performance of first and second generation panel unit root tests and undertake a more detailed comparison of the test in Herwartz and Siedenburg (2008 Herwartz, H., Siedenburg, F. (2008). Homogenous panel unit root tests under cross-sectional dependence: Finite sample modifications and the wild bootstrap. Computational Statistics and Data Analysis 53(1):137150.[Crossref], [Web of Science ®] [Google Scholar]) and its heteroskedasticity consistent Cauchy counterpart introduced in Demetrescu and Hanck (2012a Demetrescu, M., Hanck, C. (2012a). A simple nonstationary-volatility robust panel unit root test. Economics Letters 117(2):1013.[Crossref], [Web of Science ®] [Google Scholar]). As an empirical illustration, we reassess evidence on the Fisher hypothesis with data from nine countries over the period 1961Q2–2011Q2. Empirical evidence supports panel stationarity of the real interest rate for the entire subperiod. With regard to the most recent two decades, the test results cast doubts on market integration, since the real interest rate is diagnosed nonstationary.  相似文献

We develop a continuous-time model for analyzing and valuing catastrophe mortality contingent claims based on stochastic modeling of the force of mortality. We derive parameter estimates from a 105-year time series of U.S. population mortality data using a simulated maximum likelihood approach based on a particle filter. Relying on the resulting parameters, we calculate loss profiles for a representative catastrophe mortality transaction and compare them to the “official” loss profiles that are provided by the issuers to investors and rating agencies. We find that although the loss profiles are subject to great uncertainties, the official figures fall significantly below the corresponding risk statistics based on our model. In particular, we find that the annualized incidence probability of a mortality catastrophe, defined as a 15% increase in aggregated mortality probabilities, is about 1.4%—compared to about 0.1% according to the official loss profiles.  相似文献

It is generally accepted that market orientation as a well-established marketing phenomenon influences the performance of companies. However, work investigating how market oriented behaviours of customer-contact employees can be influenced is conspicuous by its absence. This article is the first empirical multilevel study in this area, which simultaneously examines intralevel-effects (effects within the level of customer-contact employees, e.g. length of work experience, job satisfaction) as well as crosslevel-effects (effects which come from superordinate managers). Based on a large-scale three-level study, the results show that the transfer of top-managers’ market orientation via sales managers down to customer-contact employees is definitely not an automatism. In fact this market orientation cascade particularly succeeds, if the market orientation of superordinate managers comes along with intense charismatic leadership. All in all, the entire impact of crosslevel-variables on the market orientation of customer-contact employees is at least as comprehensive as the influence of intralevel variables.  相似文献
