This study advances a theory of how different aspects of emotion regulation influence individual leader emergence in the intensely emotional context of nascent venture teams. Despite the growing amount of research on the role of leadership in the entrepreneurial process, the emergence of leaders in nascent venture teams has rarely been explored. Drawing on theories and research on leadership emergence and emotion regulation, we argue that the two aspects of emotion regulation (i.e., reappraisal and suppression) exert opposite effects on the degree to which nascent venture team members come to perceive an individual as a leader. We also theorize that team emotions arising from affective events moderate the relationship between reappraisal and leader emergence in such teams. Data from 103 nascent venture teams without prior leaders show a negative relationship between individuals’ trait disposition to suppress emotions and their emergence as leaders, and a positive relationship between their trait disposition to reappraise emotions and their emergence as leaders. Moreover, we find that negative team emotions magnify the positive association between reappraisal and leader emergence, while positive team emotions mitigate it. We discuss the implications of our findings for the literature on entrepreneurial leadership, entrepreneurial emotions, and leadership in general.  相似文献

This paper analyzes demographic determinants of incident experience and risk perception, as well as the relationship between the two, for eight different risk domains. Analyses were conducted by merging the results of a Swedish population-based survey, which includes approximately 15,000 individuals, with demographic and socio-economic register data. Being male was associated with higher incident experience yet a lower risk perception for nearly all risk domains. Lower socioeconomic status was associated with higher incident experience for falls, and being a victim of violence but lower incident experience for road traffic accidents. Lower socioeconomic status was also associated with higher risk perception for falls. On aggregate, ranking the different domains, respondents’ risk perception was in almost perfect correspondence to the ranking of actual incident experience, with the exception that the risk of being a victim of violence is ranked higher than indicated by actual incident experience. On a demographic group level, men and highly educated respondents perceive their risks to be lower than what is expected considering their actual incident experience.  相似文献

Based on a comparison of Berlin and Tel Aviv, this article investigates the ways in which ensembles of participatory instruments mediate between neoliberal urban regimes and political agency shaping differentially the meaning of participation and the types of claims that can be advanced. The article gives an overview of the recent history of both cities through the lens of participatory politics. Two in‐depth case studies further examine the relationship between participatory politics and claim making in each setting: the recent conflict over a social center in the district of Friedrichshain‐Kreuzberg in Berlin and the Levinsky tent city of 2011 in Tel Aviv. In the concluding section, the article suggests that, rather than assuming that participatory tools either co‐opt movements or can be appropriated by them, we need to rethink the relationship between participatory tools, rights and recognition, and ask how participatory structures and political agency constitute each other in interwoven dynamics.  相似文献

This study examines the role of an individual auditor's cognitive ability in delivering high‐quality audits. Our results from analyzing archival data from Sweden show that audit partners' IQ scores obtained from psychological tests are positively associated with going‐concern audit reporting accuracy and audit fee premiums. We also find some, albeit weak, evidence that audit partners' IQ scores are negatively associated with the income‐increasing abnormal accruals of the client. These results suggest that, although audit services are standardized through various control mechanisms and audits are conducted by teams rather than by individual auditors, the cognitive ability of audit partners responsible for an audit remains important in delivering high‐quality audit services.  相似文献

Bond laddering is a popular fixed-income investment strategy. The main purpose of this paper is to develop a methodology for determining private investors’ most interest rate risk (IRR)-return-efficient investment horizon for bond ladders (BLs), which are virtually free of credit risk. Two IRR measures of a continuously rolling and homogenous BL (CRHBL) are analytically derived under the assumption that interest rates are martingales. The first measure is the modified duration, which assumes a flat term structure of interest rates. However, this assumption is not fully supported by the empirical data and, thus, an additional IRR measure is proposed. Under each of these two measures, the ratios between the annual return in excess of the demand deposit rate and IRR of CRHBLs with different investment horizons are calculated. As expected, CRHBLs with rather low IRR are most risk-return-efficient. The results for the theoretical CRHBLs also apply to “real-world” discrete BLs. Thus, the proposed methodology can help private investors construct IRR-return-efficient discrete BLs.  相似文献

The paper develops a three-dimensional portfolio model for business relationships which distinguishes among six different categories. Based on assessments of customer profitability, customer commitment, and growth potential, the positioning of a given customer relationship in the portfolio allows managers to determine appropriate customer relationship strategies and appropriate performance indicators. Results from applying the portfolio model are reported and managerial implications and future research are discussed.  相似文献

Abstract

This is the first of two papers which report on a solvency study. The study is based on statistical analyses of policy and claims data of a portfolio of single-family houses and dwellings. This paper deals mainly with analyses of fire, windstorm, and glass liabilities. Claim frequencies and claim size distributions are estimated, and the results are used to derive moments of the annual claim amounts and to provide examples of solvency margin requirements for different classes of business. The second paper is devoted to a broader discussion of solvency margin requirements in non-life insurance.  相似文献

Efficiency and security are often regarded as opposing factors in transport operations, with increased security causing decreased efficiency. The use of information technology holds the promise of enabling improved efficiency in freight transport operations and this article suggests and elaborates on the proposition that “An increased focus on efficiency will result in improved security for carrier operations.” The research for this article involved a literature review, the collection of empirical data through one in‐depth case study, and elaboration on a proposition through a field pilot implementation. The selected focus was carrier operations in connection with port terminals carrying out RoRo operations on trailers. The article explores and describes how measures to increase efficiency result in increased security.  相似文献

Abstract

The paper provides a generalization of Hattendorff's theorem to the situation where a life insurance policy is modelled as a time-inhomogeneous Markov chain with a finite state space. It is shown that the present values of the gains obtained in the different states are zero mean martingales and that gains realized in different states are uncorrelated. Moreover, variance formulas for the present values of the gains are derived, and the results are illustrated by examples relating to term and disability insurance.  相似文献
