This paper utilises a dynamic economic approach to examine movements in fertility in Britain since 1860. The analysis and results indicate that fertility has responded positively to changes in incomes. However, this positive effect has been more than offset by the increase in the opportunity cost of female time which has followed closely the education attainment of women.An earlier version of this paper was presented to seminars at the Universities of Southampton and Hull, and the Hatfield Polytechnic. The authors would like to thank, without implementing, A. Cigno, G. Mizon and N. Rau for useful comments. 相似文献

Abstract Objective: This study assessed a Web-based cognitive-behavioral therapy (CBT) for maladaptive perfectionism, investigating perfectionism, anxiety, depression, negative automatic thoughts, and perceived stress. Participants: Participants were undergraduate students defined as maladaptive perfectionists through a screening questionnaire at an urban university. The data were collected from July 2009 to August 2010. Methods: Forty-seven maladaptive perfectionists were randomly assigned to a 12-week CBT or a wait-list control group and assessed via questionnaires at pre- and postintervention. Statistical procedures included t tests, Pearson correlations, and analysis of covariance. Results: At the postintervention measure, the CBT group demonstrated significant decreases in anxiety sensitivity and negative automatic thoughts compared to the control group. Within the CBT group, changes in perfectionism scores were significantly correlated with positive changes in depression, anxiety, stress, and automatic thoughts. Conclusions: The treatment group improved on psychological outcomes, demonstrating the effectiveness of a Web-based CBT for perfectionism in a university setting. 相似文献
