Statistical modelling of knee valgus during a continuous jump test

Landing with the knee in a valgus position is recognized as a risk factor for anterior cruciate ligament (ACL) injury. Using linear and non-linear regression analyses, the purpose of this study was to examine the correlation between two-dimensional (2D) knee valgus and three-dimensional (3D) knee kinematics measured during a jump landing task. Twenty-eight female collegiate athletes participated. All participants were required to perform a continuous jump test. The average maximum angles of abduction and internal tibial rotation during landing were measured using the Point Cluster Technique. Average peak knee valgus angle was measured using a 2D approach. Linear and non-linear regression analyses between 2D valgus and 3D knee abduction, and between 2D valgus and 3D internal tibial rotation, were performed. The R2 value between 2D valgus and 3D knee abduction was significantly different from zero and had a moderate correlation for all models, whereas the R2 value between 2D valgus and 3D internal tibial rotation was not significantly different from zero. The 2D approach could be used to screen a specific group of individuals for risk of ACL injury; however, using frontal plane 2D analysis of valgus motion to evaluate internal tibial rotation is not advised.

Social media for the community college library

Abstract

This article summarizes the experience of a multi-campus urban community college library developing and managing a social media presence. The author describes the organization of social media efforts, institutional rules that affect implementation of social media, developing themes for content, and other considerations.     

Appreciative coaching for student academic and professional development

Negative self-talk and appraisals of self-efficacy can damage students’ abilities to do well in college and lead to self-fulfilling prophesies where students fail to meet their academic and professional potentials. This multi-class activity uses appreciative coaching to help students utilize a positive mindset and achieve academic and professional goals. This coaching model, based on the tenets of appreciative inquiry, begins with a topic selection and then progresses through four stages: discover, dream, design, and destiny. The coaching process can assist instructors and students in focusing on the positive aspects of student performance, increase self-confidence, motivation to do well in courses, and proactive career planning, and create a positive learning environment.

Courses: Business Communication, Freshman Seminar, Professional Development, Senior Capstone

Objectives: The objectives of this activity are for students to (1) practice positive reframing, (2) appraise and identify their strengths and skills, (3) select goals, (4) create action plans to reach goals, and (5) be empowered and take responsibility for their academic and professional progress.     

Books Not Burgers: Six Highly Effective Ways to Motivate and Retain Library Student Employees

Although there is a healthy amount in the literature about the importance of motivating student library employees in an academic setting, very little of it discusses the practical aspects of how to motivate students. A supervisor must often use ideas from other disciplines, including the business world and academia. In this article, the author suggests six highly effective, yet cost-conscious methods that have been used successfully in an academic library setting to keep student employees motivated and to retain them year after year. These six methods are: (a) encouraging autonomy, (b) holding contests, (c) providing food, (d) being open to suggestions, (e) using employee strengths, and (f) celebrating seasonal or university-specific events.

Pupils with Severe Learning Difficulties as Personal Target Setters

Richard Rose, Senior Lecturer at University College, Northampton, and Will Fletcher and Gaynor Goodwin, Watling View School, St Albans, argue that although many schools have attempted to enable pupils with special educational needs to play an active part in their own planning procedures and assessment, few have identified and analysed the skills required by both pupils and teachers. Theydescribe a one-year small-scale action-research project, in a school for children with severe learning difficulties, which resulted in the development of procedures for the assessment of 'pupil readiness' for full involvement in the target-setting process.     

Behavioral field analysis in two strains of rats in a conditioned defensive burying paradigm

Two strains of rats (albino Wistar and hooded PVG/c) were exposed to a conditioned defensive burying paradigm that consisted of placing rats in a test chamber with bedding material on the floor, shocking them with a shock prod, and recording the time each rat spent in burying responses toward the prod. Various behaviors other than burying (freezing, grooming/paw licking) were observed by a time-sampling procedure during the control, conditioning, and extinction sessions, each of which was 15 min in duration. Wistar rats generally showed behavioral inhibition, as evidenced by less burying, lower exploratory and ambulatory behavior, and higher freezing behavior. PVG/c rats spent significantly more time engaged in burying and accumulated more bedding material in the conditioning session than did the Wistar rats. No significant differences between the two strains of rats were observed during the extinction session in terms of these measurements. The results indicate that Wistar rats have a greater tendency to freeze when coping with the noxious stimulus in a conditioned defensive burying paradigm, whereas the dominant coping style for PVG/c rats is defensive burying.
