Optional stopping refers to the practice of peeking at data and then, based on the results, deciding whether or not to continue an experiment. In the context of ordinary significance-testing analysis, optional stopping is discouraged, because it necessarily leads to increased type I error rates over nominal values. This article addresses whether optional stopping is problematic for Bayesian inference with Bayes factors. Statisticians who developed Bayesian methods thought not, but this wisdom has been challenged by recent simulation results of Yu, Sprenger, Thomas, and Dougherty (2013) and Sanborn and Hills (2013). In this article, I show through simulation that the interpretation of Bayesian quantities does not depend on the stopping rule. Researchers using Bayesian methods may employ optional stopping in their own research and may provide Bayesian analysis of secondary data regardless of the employed stopping rule. I emphasize here the proper interpretation of Bayesian quantities as measures of subjective belief on theoretical positions, the difference between frequentist and Bayesian interpretations, and the difficulty of using frequentist intuition to conceptualize the Bayesian approach. 相似文献

Numerous cross-sectional studies confirm the long-theorized association between mothers’ depression and lower parenting self-efficacy (PSE) beliefs. However, cross-sectional studies leave unanswered the direction of this association: Does depression predict PSE? Does PSE predict depression? Are both true? Does the strength of the association between depression and PSE, regardless of the direction, generalize across participant characteristics and study design features? How stable is PSE over time? And how effective are interventions at enhancing PSE? To answer these questions, we conducted a meta-analytic review of longitudinal studies. With 35 eligible studies (22,698 participants), we found support for both models: there was a significant pooled effect of both depression on PSE and of PSE on depression, with nearly identical effect sizes (d?=?????0.21 and ??0.22, respectively). The association was stronger in samples with mothers’ younger average age and studies that measured PSE among mothers relative to during pregnancy. We found a medium degree of stability in the index of PSE, d?=?0.60. Finally, the estimated pooled effect size between being in an intervention group versus control group and PSE was 0.505. Overall, we found support for (1) bidirectional associations between depression and PSE in mothers, (2) the stability of PSE over time, and (3) the strength of the relationship between PSE and depression with intervention. These results suggest the importance of continuing to develop, test, and disseminate interventions to enhance PSE. We interpret these findings in the context of both depression and low PSE having serious consequences for child outcomes and maladaptive parenting.

African American women at increased risk of HIV/sexually transmitted infection (STI) may engage in risky sex as a coping mechanism for depressed economic conditions. This study examines the association between high-risk sexual behavior and structural determinants of sexual health among a sample of young African American women. 237 young African American women (16–19 years old) from economically disadvantaged neighborhoods in North Carolina were enrolled into a randomized trial testing the efficacy of an adapted HIV/STI prevention intervention. Logistic regression analyses predicted the likelihood that young women reporting lack of food at home, homelessness and low future prospects would also report sexual risk behaviors. Young women reporting a lack of food at home (22 %), homelessness (27 %), and low perceived education/employment prospects (19 %) had between 2.2 and 4.7 times the odds as those not reporting these risk factors of reporting multiple sex partners, risky sex partners including older men and partners involved in gangs, substance use prior to sex, and exchange sex. Self-reported structural determinants of sexual health were associated with myriad sexual risk behaviors. Diminished economic conditions among these young women may lead to sexual risk due to hopelessness, the need for survival or other factors. 相似文献
Jürgen Habermas's recent challenge to secular citizens calling for greater inclusivity of religious justifications in the public sphere opens new epistemological debates that could benefit from the rich insights of feminist epistemologists. Despite certain theoretical tensions, there is some common ground between Habermas and recent work in feminist epistemology. Specifically, this article explores the shared interests between Habermas and one feminist theorist in particular, Miranda Fricker. I choose Fricker because her formulation of the epistemological and ethical hybrid virtues of testimonial justice and hermeneutical justice provide efficacious theoretical and practical tools capable of deepening the epistemological basis of Habermas's challenge to secular citizens. After a detailed analysis of Habermas's and Fricker's respective epistemological positions, I argue that Fricker's analysis provides a rich framework for thinking through questions of power, identity, and credibility with respect to religious justifications in the public sphere. In conclusion, this article emphasizes the importance of fostering more robust and just epistemic communities capable of countering the social, political, and ethical injustices of epistemic disauthorization and marginalization. 相似文献
