Characteristics of triple and quadruple toe-loops performed during the Salt Lake City 2002 Winter Olympics

The purpose of this study was to compare triple (T) and quadruple (Q) toe-loop figure skating jumps and quantify basic characteristics of these jumps to provide information to coaches that will assist them in teaching quadruple toe-loops to elite figure skaters. High-speed video was taken during men's practice and competition sessions at the 2002 Salt Lake City Winter Olympics; three-dimensional analyses of selected triple and quadruple jumps were completed. The most significant difference between triple and quadruple toe-loops was an increase in rotational velocity in the air. Additionally, increased vertical velocity at take-off and subsequent time in the air were also observed. Three main conclusions were developed: 1) The timing of rotation of the hips and shoulders was different for quadruple toe-loops compared to triples with the differences being observed before toe-pick; 2) Increases in rotational velocity occurred primarily as a result of the skaters assuming different body positions from take-off through landing which resulted in tighter rotating positions for longer durations of the jump; 3) Greater vertical velocity was gained during the propulsive phase due to the extension of the legs during the press off the ice.     

Library involvement in the implementation of a course management system

Course management system software has much to offer the faculty and students in universities that adopt this technology. Libraries have used this technology to provide links to library resources, but they can also have a role in implementing the adoption of the course management software. The Penn State College of Medicine successfully implemented the ANGEL course management system under the guidance of a medical librarian. Tasks specific to the librarian included communication and promotion of ANGEL, in addition to providing training and technical support.     

Research, publication, and service patterns of Florida academic librarians

In an effort to establish benchmarks for comparison to national trends, a web-based survey explored the research, publication, and service activities of Florida academic librarians. Participants ranked the importance of professional activities to the tenure/promotion process. Findings suggest that perceived tenure and promotion demands do influence research productivity.     

The vibrational mode structure of a golf ball

In this paper, we report the discrete frequencies at which golf balls can vibrate, the mode patterns of these vibrations and how these modes can be excited. There are two broad classes of modes: those that radiate sound waves and those that do not. Both silent and acoustic modes are excited by tangential (i.e. spin-producing) impact forces; only acoustic modes are excited by radial impact forces. Exact analytical results for a homogeneous ball core are compared with finite element numerical results for both a core and a model two-piece ball. Correspondences are readily established for the important low-frequency modes, and the good agreement suggests the validity of these results for real golf balls. The results potentially provide the basis for a rapid, simple and non-destructive method of measuring the effective high-frequency elastic shear modulae of balls (and ball cores) as well as a method for 'tuning' the performance of balls for specific clubs. Some of these aspects are explored further in our companion paper in this issue.     

Research on attitude change in U.S. students who participate in foreign study experiences: Past findings and suggestions for future research

Little research has been conducted on attitude change in U.S. students who participate in foreign study experiences. This is especially disconcerting given the number of programs available and participants involved. This research review includes five studies utilizing one-time questioning of program participants and 15 articles employing analysis of pre- and postsojourn questionnaires. Unfortunately, attitude change is seldom verified empirically in these works. Possible explanations include loosely structured experimental designs, infrequent use of follow-up studies, the lack of an established theoretical base, and perhaps most importantly, the lack of a consensus concerning what to measure. Suggestions for future research include: the study of specific variables thought to facilitate attitude change, analysis of subgroups of students similar on a particular characteristic or ability, and measurement of behavioral competencies.     

Tourette Syndrome: a Training Day for Teachers

Recent research indicates that Tourette syndrome is more prevalent than was once thought and that teachers in most mainstream schools are likely to encounter pupils displaying the characteristics of Tourette syndrome. Research also indicates that these characteristics, and the range of responses that may be appropriate, are not well understood by school staff. In this article, Dr Uttom Chowdhury, Consultant Child Psychiatrist at the CAMHS Academic Unit in Dunstable and Honorary Child Psychiatrist at the Neurodevelopmental Disorders Clinic at Great Ormond Street Hospital, London, and Dr Deborah Christie, Consultant Clinical Psychologist and Honorary Senior Lecturer at the Department of Child and Adolescent Psychological Services at University College London and Middlesex Hospitals, describe a training day for teachers facilitated by members of the Tic Disorders Clinic at Great Ormond Street Hospital. The day provided a mix of information–giving and discussion of current practice. Uttom Chowdhury and Deborah Christie relate the outcomes of the day to their own professional knowledge and experience and offer an interesting agenda for further developments.     

Social-motivational development in first grade

Social-motivational changes during first grade were studied longitudinally on a population of 89 Caucasian middle- and lower-socioeconomic status (SES) children. Results revealed that children, on the average, had a more internal locus of control, were more optimistic, and scored higher on an effectance motivation measure at the end of first grade than at the beginning. Attitudes toward school and self-esteem did not change from the beginning to the end of first grade. Changes on some social-motivational dimensions appeared to be affected by children's SES and by their academic success in first grade.     

Early career experiences of navigating journal article publication: Lessons learned using an autoethnographic approach

The successful publication of peer reviewed academic journal articles is an essential achievement for early career researchers (ECRs) seeking to establish themselves in their profession. However, this journey can pose several significant challenges for ECRs. We use an autoethnographic approach that draws deeply on our lived experience as ECRs to capture our recent and current experiences of negotiating the academic journal article publication journey to explore the tensions, contradictions, and benefits encountered in the journey. We critically examine challenges we experienced in choosing a target journal and negotiating the follow‐up process; undertaking revisions; and our experiences of limitations and possibilities in peer review and editorial support. While the peer review journal writing process has played a significant role in supporting us to become more effective ECRs, we also highlight challenges we faced negotiating ethical quandaries in this space, as well as illustrate how our preconceptions of a simple publication journey were confounded by subsequent experience of the complex realities of the space. We also suggest that educational interventions are indicated to provide ECRs support in foundational knowledge about what constitutes valuable revisions, an effective paper, and the scope of issues that can be addressed to make a paper more effective, with reference to the possibility of academic mentoring to support this need. Finally, we explore our findings in light of the tensions imposed by the relative inexperience and lack of power yielded by ECRs.     

The American Origins of BBC Local Radio

In November 1967 the first BBC Local Radio station was launched, following a successful campaign to establish the service by “founding father” Frank Gillard. He had been strongly influenced by what he had seen during a tour of U.S. broadcasters in 1954. Radio historians often cite 1 Pennsylvania station, WVPO, as having particularly impressed him. But little is known about WVPO and less still is known of the other stations, which could share some credit for influencing Gillard. Using local newspaper reports and documents held at the BBC’s Written Archive Centre, this paper looks at the American influence on BBC Local Radio.
