We conceptualize the mitigating role of trait core confidence on psychological distress in entrepreneurship manifested by occupational stress, anxiety, and depression. To facilitate field research, we first developed a short trait core confidence scale and validated it in six independent samples (N = 2,434). To test our hypothesis that trait core confidence negatively relates to base-line levels of psychological distress as well as reduces fluctuations of distress in entrepreneurship, we collected data from a 3-day entrepreneurial event called Startup Weekend across seven occasions in the United States. High trait core confidence was related to lower psychological distress both at the start of the event on Friday and at the end of it on Sunday. Core confidence remained stable from Friday to Sunday, as well as 1 month following the event, affirming its trait properties. Additionally, we measured team confidence during the event and found that high team confidence reduced psychological distress of team members. This research contributes to the research on the role of dispositions in occupational health psychology and to a better understanding of how distress of aspiring entrepreneurs is mitigated by trait core confidence. 相似文献

Keith Lehrer has been publishing on free will and compatiblism since 1960. Our concern here is to present an account of the development on his work on the subject. 相似文献

Between 2000 and 2004, 125 recreational parachuting fatalities were reported in the USA. Each was categorized using a previously reported taxonomy. While patterns of skydiving fatality were largely unchanged since the last such analysis of fatalities from 1993-1999, some variations were noted. As in previous analyses, most of the recent skydiving fatalities were the direct result of human error. Some examples of commonplace human error fatalities were turning low to the ground resulting in a hard landing, accidentally colliding with other skydivers resulting in entangled parachutes, and failure to deploy the reserve parachute correctly in the event of malfunctioning main parachute. 相似文献

Maydeu-Olivares and Joe (J. Am. Stat. Assoc. 100:1009–1020, 2005; Psychometrika 71:713–732, 2006) introduced classes of chi-square tests for (sparse) multidimensional multinomial data based on low-order marginal proportions.
Our extension provides general conditions under which quadratic forms in linear functions of cell residuals are asymptotically
chi-square. The new statistics need not be based on margins, and can be used for one-dimensional multinomials. We also provide
theory that explains why limited information statistics have good power, regardless of sparseness. We show how quadratic-form
statistics can be constructed that are more powerful than X
2 and yet, have approximate chi-square null distribution in finite samples with large models. Examples with models for truncated
count data and binary item response data are used to illustrate the theory. 相似文献

This study examined demographic and denominational differences in religious involvement (i.e., organizational, non-organizational, subjective) among Caribbean Blacks (Black Caribbeans) residing in the U.S. using data from the National Survey of American Life. Caribbean Blacks who were born in the U.S. had lower levels of religious involvement than those who immigrated and respondents originating from Haiti (as compared to Jamaica) had higher levels of religious involvement, while persons from Trinidad-Tobago reported lower service attendance than did Jamaicans. Older persons, women and married persons generally demonstrated greater religious involvement than their counterparts, while highly educated respondents expressed lower levels of self-rated religiosity. Denominational differences indicated that Baptists reported high levels of religious involvement; however, in several cases, Pentecostals and Seventh Day Adventists reported greater involvement. 相似文献

A family of Root Mean Square Error of Approximation (RMSEA) statistics is proposed for assessing the goodness of approximation in discrete multivariate analysis with applications to item response theory (IRT) models. The family includes RMSEAs to assess the approximation up to any level of association of the discrete variables. Two members of this family are RMSEA2, which uses up to bivariate moments, and the full information RMSEAn. The RMSEA2 is estimated using the M2 statistic of Maydeu-Olivares and Joe (2005, 2006), whereas for maximum likelihood estimation, RMSEAn is estimated using Pearson's X2 statistic. Using IRT models, we provide cutoff criteria of adequate, good, and excellent fit using the RMSEA2. When the data are ordinal, we find a strong linear relationship between the RMSEA2 and the Standardized Root Mean Squared Residual goodness-of-fit index. We are unable to offer cutoff criteria for the RMSEAn as its population values decrease as the number of variables and categories increase. 相似文献
