Null hypothesis significance testing uses the seemingly arbitrary probability of .05 as a means of objectively determining whether a tested effect is reliable. Within recent psychological articles, research has found an overrepresentation of p values around this cut-off. The present study examined whether this overrepresentation is a product of recent pressure to publish or whether it has existed throughout psychological research. Articles published in 1965 and 2005 from two prominent psychology journals were examined. Like previous research, the frequency of p values at and just below .05 was greater than expected compared to p frequencies in other ranges. While this overrepresentation was found for values published in both 1965 and 2005, it was much greater in 2005. Additionally, p values close to but over .05 were more likely to be rounded down to, or incorrectly reported as, significant in 2005 than in 1965. Modern statistical software and an increased pressure to publish may explain this pattern. The problem may be alleviated by reduced reliance on p values and increased reporting of confidence intervals and effect sizes.

Objective: Investigate feasibility of telehealth with remote blood pressure monitoring for management of hypertension in postpartum women at risk of severe hypertension after hospital discharge. Methods: In a single-center, prospective single-cohort feasibility study, women with hypertension in pregnancy participated in a postpartum telehealth intervention for blood pressure management after discharge. The primary feasibility outcome measures were recruitment and retention through 6 weeks postpartum. Secondary outcomes included the incidence of severe postpartum hypertension and/or need for blood pressure treatment after discharge, participant satisfaction, and 6-week hospital readmission. Participants received a tablet and equipment to transmit vital signs to a central monitoring site daily. Participants participated in telehealth or telephone visits with a nurse at 48 h and as needed. Results: Among 1413 deliveries 263 (19%) women had hypertension in pregnancy and 55/124 (47%) of women approached were consented. The retention rate was 95%. Among study participants, the incidence of severe hypertension after discharge was 9 (16%). 29 (53%) of participants required treatment due to exacerbations in blood pressure after discharge, in which 9(16%) were severe. There were no hospital readmissions. Overall 39 (86%) participants were satisfied with the remote monitoring. Conclusions: Feasibility and participant satisfaction were demonstrated. The incidence of severe hypertension and need for blood pressure treatment after discharge and during 6 weeks postpartum was 16% and 53%. Our results indicate telehealth is a promising strategy for postpartum hypertension management to decrease maternal morbidity and hospital readmission.

People tend to display the left cheek when posing for a portrait; however, this effect does not appear to generalise to advertising. The amount of body visible in the image and the sex of the poser might also contribute to the posing bias. Portraits also exhibit lateral lighting biases, with most images being lit from the left. This effect might also be present in advertisements. A total of 2801 full-page advertisements were sampled and coded for posing direction, lighting direction, sex of model, and amount of body showing. Images of females showed an overall leftward posing bias, but the biases in males depended on the amount of body visible. Males demonstrated rightward posing biases for head-only images. Overall, images tended to be lit from the top left corner. The two factors of posing and lighting biases appear to influence one another. Leftward-lit images had more leftward poses than rightward, while the opposite occurred for rightward-lit images. Collectively, these results demonstrate that the posing biases in advertisements are dependent on the amount of body showing in the image, and that biases in lighting direction interact with these posing biases.

Background: School-based violence prevention programs have shown promise for reducing aggression and increasing children's prosocial behaviors. Prevention interventions within the context of urban after-school programs provide a unique opportunity for academic researchers and community stakeholders to collaborate in the creation of meaningful and sustainable violence prevention initiatives.

Building a CBPR coalition from the ground up involving organizations of diverse size and at various stages of development presents unique challenges that can be overcome with committed leadership, clear governance principles, and appropriate infrastructure. Engagement in community-based research during the early stages, while still developing trust, structure, and governance procedures can be accomplished as long as training of all partners is conducted and the trust building is not ignored.
