We applied quantitative genetics techniques to a sample of 851 pairs of monozygotic and 855 pairs of dizygotic female twins to examine the influence of genetic factors on the variation across people in opportunity recognition. We also examined the extent to which the same genetic factors contribute to both opportunity recognition and the tendency to be an entrepreneur. We found substantial heritability for opportunity recognition (0.45), with no influence of the shared environment. Moreover, we found that 53% of the phenotypic correlation between opportunity recognition and the tendency to be an entrepreneur had a common genetic aetiology. 相似文献

The objective was to examine the association of parental locus of control (PLOC) with pediatric quality of life (QOL) for
children with sickle cell disease (SCD), specifically addressing the potential mediating role of family functioning. Associations
with disease severity were also investigated. Thirty-one primary caregivers completed standard measures of parental locus
of control, family functioning, and quality of life during their child's inpatient admission for pain or fever. Results indicated
that the PLOC total score was significantly associated with QOL in terms of self-competence and showed marginal significance
with QOL social competence; it was significantly negatively correlated with family functioning. The association of the PLOC
with QOL subscales was maintained when controlling for family functioning. Disease severity was not associated with PLOC scores.
Primary caregivers endorsed more external parental locus of control beliefs. Further investigation of the association of caregiver
appraisals and family functioning is warranted with the goal of addressing the stress that disease management with sickle
cell may add to parent–child relationships. 相似文献

The study examined the relationship between examinees’ test-taking effort and their accuracy rate on items from the PISA 2015 assessment. The 10% normative threshold method was applied on Science multiple-choice items in the Cyprus sample to detect rapid guessing behavior. Results showed that the extent of rapid guessing across simple and complex multiple-choice items was on average less than 6% per item. Rapid guessers were identified, and for most items their accuracy was lower than the accuracy for students engaging in solution-based behavior. A number of plausible explanations were graphically evaluated for items for which accuracy was higher for the rapid guessing subgroup. Overall, this empirical investigation presents original evidence on test-taking effort as measured by response time in PISA items and tests propositions of Wise’s (2017) Test-Taking Theory. 相似文献
