Sexual Violence, Consent, and Contradictions: A Call for Communication Scholars to Impact Sexual Violence Prevention

The goal of this paper is to provide an overview of the conflicting findings from existing sexual violence and consent communication research with the intention of motivating communication scholars to study these areas. Generally, normative roles and alcohol add to the inherent complexity of consent communication. Moreover, contradictory findings in the literature make it difficult to define a practicable approach to the reduction of sexual violence across college campuses. This paper broadly reviews the current literature in this area of research with the ultimate goal of creating a guiding research agenda based in communication theory. Sexual violence prevention programming may benefit from this insight gleaned from communication research. For future research, we suggest consent communication, sexual negotiation, and other factors influencing sexual violence as topics that may inform more specifically targeted prevention programming, leading to measurable reduction in the instances of sexual violence

Physical Educators’ Efficacy in Utilising Paraprofessionals in an Inclusive Setting

Inclusion of students with disabilities (SwD) in Australian health and physical education (HPE) classes is on the rise. Reasonable adjustment to assist inclusive practice is often accomplished through the use of teaching assistants, or paraprofessionals. While this practice is commonly understood within the classroom, this approach remains obscure in the HPE setting. The purpose of this study was to explore how Australian HPE teachers utilise paraprofessionals when teaching SwD in inclusive environments. HPE teachers (N=14) completed an online questionnaire inquiring how paraprofessionals are being used and the strategies they are using to develop working relationships with paraprofessionals. The HPE teachers in our sample generally had a favourable attitudes towards the paraprofessionals they have worked with, however a lack of appropriate training and HPE curriculum knowledge were highlighted as deficient areas that may have an adverse effect on the overall HPE environment. While the paraprofessionals were recognised as providing a level of support that was generally to the satisfaction of the HPE teachers, the HPE teachers’ consistently provided areas in which the paraprofessional could improve. Strategies to foster this collaborative working relationship were also investigated, and the primary finding dealt with adequate reciprocal communication. With the move toward inclusive practice in Australian public schools this is an area that warrants further investigation so all students can benefit from a healthy and productive HPE

Expression, Purification, and Analysis of Unknown Translation Factors from Escherichia coli: A Synthesis Approach

New approaches are currently being developed to expose biochemistry and molecular biology undergraduates to a more interactive learning environment. Here, we propose a unique project-based laboratory module, which incorporates exposure to biophysical chemistry approaches to address problems in protein chemistry. Each of the experiments described herein contributes to the stepwise process of isolating, identifying, and analyzing a protein involved in a central biological process, prokaryotic translation. Students are provided with expression plasmids that harbor an unknown translation factor, and it is their charge to complete a series of experiments that will allow them to develop hypotheses for discovering the identity of their unknown (from a list of potential candidates). Subsequent to the identification of their unknown translation factor, a series of protein unfolding exercises are performed employing circular dichroism and fluorescence spectroscopies, allowing students to directly calculate thermodynamic parameters centered around determining the equilibrium constant for unfolding as a function of denaturant (temperature or chemical). The conclusion of this multi-part laboratory exercise consists of both oral and written presentations, emphasizing synthesis of the roles of each translation factor during the stepwise process of translation

Effect of different spatial normalization approaches on tractography and structural brain networks

To facilitate the comparison of white matter morphologic connectivity across target populations, it is invaluable to map the data to a standardized neuroanatomical space. Here, we evaluated direct streamline normalization (DSN), where the warping was applied directly to the streamlines, with two publically available approaches that spatially normalize the diffusion data and then reconstruct the streamlines. Prior work has shown that streamlines generated after normalization from reoriented diffusion data do not reliably match the streamlines generated in native space. To test the impact of these different normalization methods on quantitative tractography measures, we compared the reproducibility of the resulting normalized connectivity matrices and network metrics with those originally obtained in native space. The two methods that reconstruct streamlines after normalization led to significant differences in network metrics with large to huge standardized effect sizes, reflecting a dramatic alteration of the same subject’s native connectivity. In contrast, after normalizing with DSN we found no significant difference in network metrics compared with native space with only very small-to-small standardized effect sizes. DSN readily outperformed the other methods at preserving native space connectivity and introduced novel opportunities to define connectome networks without relying on gray matter parcellations. Direct streamline normalization (DSN) directly warps the streamlines into any template space by using the transformations output from Advanced Normalization Tools (ANTs). DSN overcomes the limitations of diffusion weighted images (DWI) spatial normalization. It allows DWIs to be acquired with any desired sampling scheme. Fiber orientation distributions (FODs) or orientation distribution functions (ODFs) can also be reconstructed using any desired method and streamlines generated using any algorithm. Most importantly, it avoids the problem of generating tracts from FODs or ODFs that have become distorted because of spatial normalization. Our results show that DSN has minimal influence on tractography measures such as tract count and structure and does not significantly alter structural networks with only very small to small effect sizes. We have developed a framework in Python that works with most diffusion software platforms. It is available at http://github.com/clintg6/DSN

Potential health impact and cost-effectiveness of bivalent human papillomavirus (HPV) vaccination in Afghanistan.

INTRODUCTION: Human papillomavirus (HPV) vaccination has not been introduced in many countries in South-Central Asia, including Afghanistan, despite the sub-region having the highest incidence rate of cervical cancer in Asia. This study estimates the potential health impact and cost-effectiveness of HPV vaccination in Afghanistan to inform national decision-making. METHOD: An Excel-based static cohort model was used to estimate the lifetime costs and health outcomes of vaccinating a single cohort of 9-year-old girls in the year 2018 with the bivalent HPV vaccine, compared to no vaccination. We also explored a scenario with a catch-up campaign for girls aged 10-14 years. Input parameters were based on local sources, published literature, or assumptions when no data was available. The primary outcome measure was the discounted cost per disability-adjusted life-year (DALY) averted, evaluated from both government and societal perspectives. RESULTS: Vaccinating a single cohort of 9-year-old girls against HPV in Afghanistan could avert 1718 cervical cancer cases, 125 hospitalizations, and 1612 deaths over the lifetime of the cohort. The incremental cost-effectiveness ratio was US$426 per DALY averted from the government perspective and US$400 per DALY averted from the societal perspective. The estimated annual cost of the HPV vaccination program (US$3,343,311) represents approximately 3.53$586) from both the government and societal perspective with additional health benefits generated by a catch-up campaign, depending on the government's willingness to pay for the projected health outcomes

Statistical significance and sports medicine trials

Objectives: Lowering the threshold for statistical significance in medical research from a P value of .05 to .005 was recently proposed to reduce misinterpretation of study results. What effect this proposal would have on orthopaedic sports medicine literature is currently unclear.Research Question/Hypothesis: We seek to determine how the newly proposed threshold could affect the interpretation of previously published sports medicine RCTs.Methods: We searched PubMed from January 01, 2016 to December 31, 2017 for RCTs published in the American Journal of Sports Medicine, Arthroscopy, and Knee Surgery, Sports Traumatology, Arthroscopy. We extracted P value data for primary endpoints, since RCTs are most often powered for these endpoints. We used Google Forms for data extraction and STATA 13.1 for the data analysis.Results: Of the 159 studies, only 13 (8%) of the studies have endpoints in which all P values are below the new threshold of .005. 40 (25%) of the studies have endpoints in which some would meet the new P value threshold of .005, and some would not meet this new threshold. 106 (67%) of the studies have no endpoints in which the P value(s) was less than .005. Overall, 38% (59/157) of the previously statistically significant primary endpoints were less than .005, while 62% (98/157) would be reclassified as suggestive.Conclusions: Of statistically significant endpoints in our sample, only 17% (59/350) would maintain their statistical significance with a P value threshold of less than .005, and only 8% of studies would maintain their overall significance with all P values falling below the new threshold
