Mastery Teachers: How to Build Success for Each Student in Today’s Classrooms

The purpose of this mixed methods research study was to investigate the efficacy of master teachers (n=60) and analyze the factors which support their success motivating and instructing P-12 students and effectively managing the classroom. The research design of this case study used an exploratory sequential mixed methods design (Creswell, 2015). The Teacher Self Efficacy Scale (TSES) (long form) sought to discover the capabilities teachers perceive having related to student engagement, instructional strategies, and classroom management (Tschannen-Moran & Hoy, 2001). Participant teachers were interviewed through one-to-one conversation, to verify and enrich the findings (Bogdan &; Biklen, 2007) produced by the TSES. Our findings suggest master teachers are passionate about teaching; however, struggle at times with learners who have learning difficulties and off task behavior. Building relationships and developing social emotional skills is one of the most powerful tools for empowering students leading to their success. We also found efficacious teachers engage students in learning by relating to the real world, connecting to student interests, setting clear expectations, and establishing routines

ENGINEERING AN OLEOGINOUS YEAST FOR THE PRODUCTION OF BIODIESEL

poster abstractThere are economic and social interests in replacing the current energy dependence we have on petroleum-based oleochemicals. Yarrowia lipolytica, an oleaginous yeast, has the ability to metabolize unique carbon sources, particularly hydrocarbons and to accumulate large amounts of lipids which could be developed into a source of biodiesel. The ability of Y. lipolytica to accumulate triacylglycerols in lipid droplets and the complete sequencing of its genome make Y. lipolytica a viable organism to genetically engineer for the production of large quantities of biodiesel precursors. The purpose of this project is to genetically modify Y. lipolytica to further increase its production of triacylglycerols by knocking out genes that encode enzymes involved in the β-oxidation of fatty acids. This genetic modification will be accomplished by using homologous recombination to disrupt the genes POX3-5 and POT1. The 5’ and 3’ untranslated regions of POX3-5 and POT1 were amplified by polymerase chain reaction and cloned to allow a drug resistance gene to be introduced between them. Following cloning, these genes will be knocked out from the Y. lipolytica genome using drug resistance as a marker. The disruption of these genes is expected to increase the accumulation of triacylglycerols in Y. lipolytica lipid droplets versus the wild-type. Progress towards the goals of this project will be reported

Experience of an anatomic femoral stem in a UK orthopaedic centre beyond 20 years of follow-up

Introduction Increasing interest in the use of anatomical stems has developed as the prevalence of periprosthetic fractures (PPFs) continues to increase. The primary aim of this study was to determine the long-term survivorship and PPF rate of an anatomical femoral stem in a single UK centre. Patients and methods Between 2000 and 2002, 94 consecutive THAs were performed using the 170 mm Lubinus SP II anatomical femoral stem in our institution. Patient demographics, operative details and clinical outcomes were collected prospectively in an arthroplasty database. Patient records and national radiographic archives were reviewed finally at a mean of 21.5 years (SD 0.7) following surgery to identify occurrence of subsequent revision surgery, dislocation or periprosthetic fracture. Results Mean patient age at surgery was 65.8 years (SD 12.5, 34–88 years). There were 48 women (51%). Osteoarthritis was the operative indication in 88 patients (94%). Analysis of all-cause THA failure demonstrated a survivorship of 98.5% (95% confidence interval [CI], 98.0–99.3%) at 10 years and 96.7% (94.5–98.9%) at 21 years. The 20-year stem survival for aseptic loosening was 100% with no cases of significant lysis found (lucent line > 2 mm) and no stems required revision. Patient demographics did not appear to influence risk of revision (p > 0.05). There were 2 revisions in total (2 for acetabular loosening with original stems retained). There were no PPFs identified at mean 21.5 year follow-up and 5 dislocations (5%). Conclusions The Lubinus SP II 170 mm stem demonstrated excellent survivorship and negligible PPF rates over 20 years following primary THA.Peer reviewe

Glycine max and Glycine soja are capable of cold acclimation

Soybean has been considered a cold intolerant species; based largely upon seed germination and soil emergent evaluations. This study reports a distinct acquisition of cold tolerance, in seedlings, following short acclimation periods. Diversity in cold responses was assessed in eight cultivars of Glycine max and six accessions of G. soja. All varieties of soybean significantly increased in freezing tolerance following acclimation. This study indicates soybean seedlings are indeed capable of sensing cold and acquiring cold tolerance. Germination rates after cold imbibition were negatively correlated with maturity group, but positively correlated with cold acclimation potential in G. soja. Seed fatty acid composition was varied between the species, with Glycine soja accessions containing about 2-times more linolenic acid (18:3) than G. max. Furthermore, high levels of linoleic acid (18:2) in seeds were positively correlated with germination rates following cold imbibition in G. soja only. We suggest that domestication has not impacted the overall ability of soybean to cold acclimate at the seedling stage and that there is little variation within the domesticated species for ability to cold acclimate. Thus, this brief comparative study reduces the enthusiasm for the “wild” species as an additional source of genetic diversity for cold tolerance

Attendance patterns and factors affecting participation in organized walks: an investigation of Natural England's Walking for Health programme

This paper examines the Natural England database of registered walkers to identify patterns of attendance in organized walks and differences in walking behaviour based on the profile of participants in Walking for Health (WfH), one of the largest public health interventions for physical activity in the UK. The investigation is informed by walk-history data relating to more than 79,000 participants over a two-year period. Methods used include measures of participant adherence and chi-squared automatic interaction detector analysis. The results indicate that absolute participation numbers have a strong seasonal element, with a marked decline occurring around the Christmas period. Age emerges as the most significant determinant of organized walking behaviour, with older age groups exhibiting higher intensity of participation relative to younger age groups. The research facilitates a better understanding of participation in WfH and can serve to inform future delivery and the marketing of organized walking initiatives
