Influence of shaft length on golf driving performance

The aim of this study was to determine how shaft length affects golf driving performance. A range of drivers with lengths between 1.168 m and 1.270 m, representing lengths close to the 1.219 m limit imposed by R&;A Rules Limited (2008 R&;A Rules Limited. 2008. Rules of golf, St. Andrews: R&;A Rules Limited, The Royal and Ancient Golf Club of St. Andrews.  [Google Scholar]), were assembled and evaluated. Clubhead and ball launch conditions and drive distance and accuracy were determined for seven category 1 golfers (handicaps 0.21 ± 2.41) who performed shots on a purpose-built practice hole. As shaft length increased from 1.168 m to 1.270 m, initial ball velocity increased (+1.8 m/s, P < 0.01). Ball carry (+4.3 m, P = 0.152) also increased, although not significantly so. Furthermore, as shaft length increased, for all club comparisons there was no decrease in accuracy. Ball launch conditions of spin components and launch angle remained unaffected by shaft length. Launch angle increased (0.8°, F = 1.074, P = 0.362) as driver shaft length increased. Our results show that clubhead and ball velocity together with ball carry tended to increase with no loss of accuracy.     

Software for calculating blood lactate endurance markers

Abstract

Blood lactate markers are used as summary measures of the underlying model of an athlete's blood lactate response to increasing work rate. Exercise physiologists use these endurance markers, typically corresponding to a work rate in the region of high curvature in the lactate curve, to predict and compare endurance ability. A short theoretical background of the commonly used markers is given and algorithms provided for their calculation. To date, no free software exists that allows the sports scientist to calculate these markers. In this paper, software is introduced for precisely this purpose that will calculate a variety of lactate markers for an individual athlete, an athlete at different instants (e.g. across a season), and simultaneously for a squad.     

A nationwide comparative study between private and public university students’ soft skills

The main function of Higher Educational Institutions (HEIs) is to produce skilled and knowledgeable workforce who are able to not only function with minimal guidance but also to contribute effectively to the hiring organizations. Many studies have indicated that most HEIs have somewhat similar course content and thrived at producing students with good academic achievement. But what differentiated them from one another is their ability to develop knowledge workers with the right employability skills or ??soft skills?? such as communication, problem-solving, interpersonal and other skills deemed important as the foundations by which they require to function at work regardless of the nature of employment. This paper reports findings of a large-scale study looking into the soft skills attainment of Malaysian HEI graduates. A quantitative survey design was employed whereby data were obtained through the administration of an instrument called the Malaysian Soft Skills Scale (My3S). My3S consists of 180 items covering seven elements namely Communications, Critical Thinking and Problem Solving, Teamwork, Moral and Professional Ethics, Leadership, Life Long Learning and Entrepreneurial aspects. The mean scores for the seven My3S subscales were found to be between 6.3 and 7.8 from the maximum possible score of 10. Specifically, comparisons were made between graduates of public and private institutions with respect to the seven elements. Findings of the study suggest that, in general, students of public HEIs scored higher in all seven skills. With respect to gender, male students scored higher than female students in all elements except for teamwork skills and moral and professional ethics. A comparison between fields of study showed that for both types of HEIs, technical students scored the highest in all skills except for moral and professional ethics. Based on the findings of this study, it is suggested that in addition to offering specific courses to improve soft skills attainment, HEIs need to embed soft skills in their academic curricula.     

Communicating Science to Impact Learning? A Phenomenological Inquiry into 4th and 5th Graders’ Perceptions of Science Information Sources

Rooted in science education and science communication studies, this study examines 4th and 5th grade students’ perceptions of science information sources (SIS) and their use in communicating science to students. It combines situated learning theory with uses and gratifications theory in a qualitative phenomenological analysis. Data were gathered through classroom observations and interviews in four Turkish elementary schools. Focus group interviews with 47 students and individual interviews with 17 teachers and 10 parents were conducted. Participants identified a wide range of SIS, including TV, magazines, newspapers, internet, peers, teachers, families, science centers/museums, science exhibitions, textbooks, science books, and science camps. Students reported using various SIS in school-based and non-school contexts to satisfy their cognitive, affective, personal, and social integrative needs. SIS were used for science courses, homework/project assignments, examination/test preparations, and individual science-related research. Students assessed SIS in terms of the perceived accessibility of the sources, the quality of the content, and the content presentation. In particular, some sources such as teachers, families, TV, science magazines, textbooks, and science centers/museums (“directive sources”) predictably led students to other sources such as teachers, families, internet, and science books (“directed sources”). A small number of sources crossed context boundaries, being useful in both school and out. Results shed light on the connection between science education and science communication in terms of promoting science learning.     

‘To show or No-show’? Therapist Racial-ethnic Disparities in Clients’ Nonattendance in Therapy

Clients’ nonattendance in therapy poses a significant threat to the effective delivery of mental health services at university counseling centers. As such, researchers have investigated processes related to clients’ nonattendance in an effort to increase treatment utilization and treatment outcomes. However, there is a paucity of research testing the impact of the therapist on clients’ nonattendance patterns. Additionally, it is unknown whether therapists vary in the nonattendance of their racial/ethnic minority (REM) and White clients. Therefore, the present study sought to identify therapist effects in client nonattendance rates, and examine between-therapist disparities in REM and White clients’ nonattendance patterns. Data for this study consisted of 275 REM and 341 White clients seen by 21 therapists at a large university counseling center. Results indicated that therapists accounted for 14% of the variability in clients’ nonattendance. Additionally, therapist effects in nonattendance due to clients’ REM status were identified, suggesting that therapists are a significant source of racial/ethnic disparities in clients’ nonattendance. REM clients’ nonattendance rates were higher compared to White clients for some therapists, but not others. Clinical implications and future research are discussed.
