“…33,34 Effect size allows for comparisons across studies by reporting the strength of the treatment or intervention regardless of sample size. 33,35 For example, a comparison is made between a "flipped" course and a lecturebased course and reports a significant change in mean examination scores from 80% to 82% (with a standard deviation of 610). While this may be a significant change, the resultant effect size is 0.2 (ie, the average performance of a student in the "flipped" course is 0.2 standard deviations above the average performance in the "lecture" course).…”

It is the collaborative responsibility of authors, reviewers, and editors to produce high-quality manuscripts that advance knowledge and educational practice. Experience with manuscript submissions to the American Journal of Pharmaceutical Education reveal several areas for improvement that authors can make to increase their submission success rate during the review process. These improvements include research question justification, improved clarity and details regarding methodology, concise data and results, and a discussion that frames research findings in the context of what is already known. This paper summarizes common flaws we see in submitted manuscripts and makes suggestions on how to address these areas and improve publication success.

“…Error bars represent 95% Highest Posterior Density, and are analogous in practice to 95% frequentist confidence intervals (Hadfield 2010). In keeping with the exploratory nature of this study, for the purposes of discussion we relax the credibility threshold to 90%, and additionally that displayed an effect size commensurate with other credible predictors (Kirk 1996, Coe 2002, Maher et al 2013). …”

Grassroots engagement with transition to sustainability: diversity and modes of participation in the international permaculture movement

ABSTRACT. Grassroots networks and social movements are increasingly regarded as agents of change that can help respond to environmental degradation both by generating novel solutions to existing problems and influencing institutions toward more substantive responses. We examine permaculture, an international movement that, despite its broad international distribution and relatively high public profile, has received little systematic scrutiny in the scientific literature. We attempt to remedy that gap by conducting a broad international (though English-only) survey of 731 permaculture participants, and assessing the socio-demographic characteristics of the movement. The survey examined self-identified roles of permaculture participants and explored the relationships between those roles and socio-demographic factors race, gender, and socioeconomic status. The influence of structural factors on participant roles was examined by including multidimensional national indices development, inequality, and ecosystem vitality, for the 45 countries in the sample. Results showed the participation of women at or above parity (53%), while participation by race showed a white supermajority (96%). Multivariate regression demonstrated that race, gender, and socioeconomic status are shaping participation in distinct ways and that each interact with structural factors. The effects of gender on social roles varied with ecosystem vitality, with women scoring higher than men in countries with high levels of ecosystem vitality, and the reverse where ecosystem vitality was low. The observed effect of race on practice varied with national inequality, such that the scores of respondents of color were equivalent to white respondents in countries with the least inequality, but descended as inequality increased, while whites were unaffected. Different indicators of socioeconomic status depressed and amplified different dimensions of participation. Results point toward a theoretical framework that identifies multiple levels and sites through which socio-demographic factors shape participation in grassroots environmental action, and the outlines of such a framework are discussed.

Objectives: This study aims to investigate the presence and levels of Staphylococcal enterotoxin B (SEB) in chronic rhinosinusitis (CRS) cases with or without nasal polyps. Patients and Methods:The study included 38 patients with CRS. Patients were divided into two groups as CRS group with nasal polyps (group A, n=18) and CRS group without nasal polyps (group B, n=20). The control group (group C) consisted of 15 patients. Staphylococcal enterotoxin B levels were measured in concha supernatants and serum samples in all three groups and in polyp tissues in group A by using enzyme-linked immunosorbent assay. Real-time polymerase chain reaction analysis was used to reveal enterotoxin B gene expression in polyp and concha tissue samples. Results:Staphylococcal enterotoxin B levels were positive in 11 (78.6%) and 11 (55.0%) patients, and in one (6.7%) patient in group A, B, and C, respectively. A statistically significant difference was detected between groups in terms of SEB positivity (p<0.0001). When the numbers of SEB gene copies were compared between the groups, there were statistically significant differences between groups A and C (p<0.0001), and between groups B and C (p=0.002). Conclusion:Higher rates of SEB positivity in serum samples and higher numbers of SEB gene copies in concha samples indicate that Staphylococcal superantigens may be associated with CRS development.Keywords: Enterotoxin B; nasal polyp; rhinosinusitis; Staphylococcus aureus; superantigen. ÖZ Amaç: Bu çalışmada nazal polipi olan veya olmayan kronik rinosinüzit (KRS) olgularında Stafilokokal enterotoksin B (SEB) varlığı ve seviyesi araştırıldı.Hastalar ve Yöntemler: Çalışmaya KRS'li 38 hasta dahil edildi. Hastalar nazal polipli KRS grubu (grup A, n=18) ve nazal polipsiz KRS grubu (grup B, n=20) olmak üzere iki gruba ayrıldı. Kontrol grubunu (grup C) 15 hasta oluşturdu. Stafilokokkal enterotoksin B seviyeleri enzim-bağımlı immünosorbent analiz kullanılarak her üç grupta konka süpernatantlarında ve serum örneklerinde ve grup A'da polip dokularında ölçüldü. Polip ve konka doku örneklerinde enterotoksin B gen ekspresyonunu ortaya koymak için gerçek zamanlı polimeraz zincir reaksiyon analizi kullanıldı.Bulgular: Grup A, B ve C'de SEB seviyeleri sırasıyla 11 (%78.6) ve 11 (%55) hastada ve bir (%6.7) hastada pozitif idi. Gruplar arasında SEB pozitifliği açısından istatistiksel olarak anlamlı derecede farklılık saptandı (p<0.0001). Gruplar arasında SEB gen kopyası sayıları karşılaştırıldığında, grup A ile C arasında (p<0.0001) ve grup B ile C arasında (p=0.002) istatistiksel olarak anlamlı derecede farklılıklar vardı.Sonuç: Serum örneklerinde daha yüksek oranlarda SEB pozitifliği ve konka örneklerinde daha yüksek sayılarda SEB gen kopyası olması, Stafilokokal süperantijenlerin KRS gelişimi ile ilişkili olabileceğini gösterir.

The Other Half of the Story: Effect Size Analysis in Quantitative Research

Abstract: Effect size measures are a key complement to statistical significance testing when reporting quantitative research findings. The authors provide a rationale for use of effect size and specific tools and guidelines for interpretation of results.
