The Relationship Between Personality Type And Exercise Motivation

Purpose: The purpose of this study was to provide further understanding of the complex nature of physical activity motivation. Specifically, the purpose of this study was to analyze personality type and internal/external autonomous regulation. Method: Subjects were college students age 18 years and older who attended the Fitness Five Project. Data collected from the Ten-Item Personality Inventory and the RM 4-FM: Motivation for Physical Activity Questionnaire were analyzed using a bivariate correlation. Results: Statistical analyses revealed the personality traits extraversion, agreeableness, conscientiousness, and emotional stability were positively associated with intrinsic motivation. Results showed the personality trait openness to experience was negatively associated with intrinsic motivation. Summary: Intrinsic and extrinsic motivation are both important for different reasons. It is clear from current and past research that extrinsic motivation would benefit the adoption of a new activity and intrinsic motivation would benefit the consistency and adherence to the activity

Germline Cas9 expression yields highly efficient genome engineering in a major worldwide disease vector, Aedes aegypti.

The development of CRISPR/Cas9 technologies has dramatically increased the accessibility and efficiency of genome editing in many organisms. In general, in vivo germline expression of Cas9 results in substantially higher activity than embryonic injection. However, no transgenic lines expressing Cas9 have been developed for the major mosquito disease vector Aedes aegypti Here, we describe the generation of multiple stable, transgenic Ae. aegypti strains expressing Cas9 in the germline, resulting in dramatic improvements in both the consistency and efficiency of genome modifications using CRISPR. Using these strains, we disrupted numerous genes important for normal morphological development, and even generated triple mutants from a single injection. We have also managed to increase the rates of homology-directed repair by more than an order of magnitude. Given the exceptional mutagenic efficiency and specificity of the Cas9 strains we engineered, they can be used for high-throughput reverse genetic screens to help functionally annotate the Ae. aegypti genome. Additionally, these strains represent a step toward the development of novel population control technologies targeting Ae. aegypti that rely on Cas9-based gene drives

Social Media Practices of School Administrators: The Time is Now

The educational disruption caused by COVID-19 increased awareness of the value of organizational resiliency/sustainability and the critical need for administrators to provide timely communication among all stakeholders. If preparation programs are to provide administrators with the skills and knowledge to effectively use social media as a communication tool, we must explore the practices and perceptions of school administrators’ use of social media to communicate with stakeholders and to identify their recommended social media communication practices. The Social Media as a Tool to Effectively Communicate with Stakeholders Survey and interviews were used for data collection. Findings are focused on comfort levels, perceived effectiveness, benefits, concerns, and recommended practices reported by the school administrators who participated in the study. While, social media was found to be an effective communication tool that can promote and support positive public relations, there were noted gaps in self-efficacy and best practices of the reporting administrators. Research literature, preparation programs, and practicing administrators will equally benefit from the outcomes of this study

Indigenous Voice Closing the Gap and Putting Communication for Social Change into Practice

Australian journalism schools are full of students who have never met an Aboriginal or Torres Strait Islander and who do not know their history. Journalism educators are illequipped to redress this imbalance as the large majority are themselves non-Indigenous and many have had little or no experience with the coverage of Indigenous issues. Such a situation calls for educational approaches that can overcome these disadvantages and empower journalism graduates to move beyond the stereotypes that characterise the representation of Indigenous people in the mainstream media. This paper will explore three different courses in three Australian Tertiary Journalism Education Institutions who use Work Integrated Learning approaches to instil the cultural competencies necessary to encourage a more informed reporting of Indigenous issues. The findings from the three projects illustrate the importance of adopting a collaborative approach between the industry, the Indigenous community and educators to ensure a significant impact on the students’ commitment to quality journalism practices when covering Indigenous issues

Can Placental Corticotropin-Releasing Hormone Inform Timing of Antenatal Corticosteroid Administration?

Context Antenatal corticosteroids are commonly administered to pregnant women at risk for delivering between 23 and 34 gestational weeks; they provide crucial benefits to fetal lung maturation and reduce risk for neonatal morbidity and mortality. Corticosteroids are maximally efficacious for lung maturation when administered within 2 to 7 days of delivery. Accurately identifying the timing of preterm delivery is thus critical to ensure that antenatal corticosteroids are administered within a week of delivery and to avoid unnecessary administration to women who will deliver at term. A plausible biomarker for predicting time of delivery is placental corticotropin-releasing hormone (pCRH). Objective To assess whether pCRH concentrations predict time to delivery and specifically which women will deliver within a week of treatment. Design pCRH concentrations were evaluated before administration of the corticosteroid betamethasone, and timing of delivery was recorded. Participants A total of 121 women with singleton pregnancies who were prescribed betamethasone. Results Elevated pCRH concentrations were associated with a shorter time from treatment to delivery. Receiver-operating characteristic curves revealed that pCRH may improve the precision of predicting preterm delivery. Conclusions In the current sample, pCRH concentrations predicted the likelihood of delivering within 1 week of corticosteroid treatment. Current findings suggest that pCRH may be a diagnostic indicator of impending preterm delivery. Increasing the precision in predicting time to delivery could inform when to administer antenatal corticosteroids, thus maximizing benefits and reducing the likelihood of exposing fetuses who will be delivered at term

Vaccine hesitancy in migrant communities: a rapid review of latest evidence.

By refusing or delaying vaccination, vaccine hesitant individuals and communities undermine the prevention, and ultimately, elimination of communicable diseases against which safe and effective vaccines are available. We reviewed recent evidence of vaccine hesitancy within migrant communities in the context of increased human mobility and widespread anti-immigrant sentiment and manifest xenophobia. Among many immigrant parents and families, vaccine hesitancy is largely associated with fears and misinformation about vaccine harms, limited knowledge of both preventable diseases and vaccines, distrust of host countries' health systems and their attendant intentions, language barriers, and perceived incompatibility between vaccine uptake and migrants' religion. Hesitancy toward measles, influenza, and human papillomavirus vaccines are most discernible, and main migrant populations involved include Somalis and Poles

Pointing all around you : selection performance of mouse and ray-cast pointing in full-coverage displays

Funding: SurfNet (NSERC, Canada), EPSRC (Small Equipment Grant).As display environments become larger and more diverse - now often encompassing multiple walls and room surfaces - it is becoming more common that users must find and manipulate digital artifacts not directly in front of them. There is little understanding, however, about what techniques and devices are best for carrying out basic operations above, behind, or to the side of the user. We conducted an empirical study comparing two main techniques that are suitable for full-coverage display environments: mouse-based pointing, and ray-cast `laser' pointing. Participants completed search and pointing tasks on the walls and ceiling, and we measured completion time, path lengths and perceived effort. Our study showed a strong interaction between performance and target location: when the target position was not known a priori the mouse was fastest for targets on the front wall, but ray-casting was faster for targets behind the user. Our findings provide new empirical evidence that can help designers choose pointing techniques for full-coverage spaces.Postprin
