Quantifying elbow extension and elbow hyperextension in cricket bowling: a case study of Jenny Gunn

In this study a method for determining elbow extension and elbow abduction for a cricket bowling delivery was developed and assessed for Jenny Gunn who has hypermobility in both elbows and whose bowling action has been repeatedly queried by umpires. Bowling is a dynamic activity which is assessed visually in real time in a cricket match by an umpire. When the legality of a bowler's action is questioned by an umpire a quantitative analysis is undertaken using a marker based motion analysis system. This method of quantifying elbow extension should agree with a visual assessment of when the arm is "straight" and should minimise the effects of marker movement. A set of six markers on the bowling arm were used to calculate elbow angles. Differences of up to 1° for elbow extension and up to 2° for elbow abduction were found when angles calculated from the marker set for static straight arm trials were compared with measurements taken by a chartered sports physiotherapist. In addition comparison of elbow extension angles at ball release calculated from the markers during bowling trials with those measured from high speed video also showed good agreement with mean differences of 0°±2°.     

Correlates of sexual abuse and smoking among French adults

OBJECTIVE: The goal of this study was to examine the association between sexual abuse (SA) and initiation, cessation, and current cigarette smoking among a large representative adult population in France. METHOD: A random sample size of 12,256 adults (18-75 years of age) was interviewed by telephone concerning demographic variables, health practices and beliefs, and health status--for which SA and tobacco questions were included. Bivariate and multivariate analyses were conducted. RESULTS: Nearly 46% of SA survivors were current smokers compared to 34% of non-abused persons (p<.001). Survivors of SA consumed more cigarettes per day than non-abused individuals (14.5 vs. 12.4, p<.01). Survival analysis showed an increased risk of smoking initiation for respondents abused before 18 (adjusted relative hazard=1.55; p<.0001) with referent to the non-abused group. SA was not found to be a significant predictor of current smoking status among those who began smoking after the first incident of SA. Respondents who were not sexually abused were 1.8 times (95% CI, 1.12-2.99) more likely to quit smoking than people who began smoking after they were sexually abused. CONCLUSIONS: The early identification and treatment of sexually abused persons is critical to decrease smoking among adolescents and adults because of the association of SA with both smoking initiation and decreased cessation rates. It may be more difficult to detect an association between SA and current smoking due to the high rates of smoking and lower rates of quitting among the general French population.     

Reflections on the First International iPED Conference,Coventry TechnoCentre,UK, 10–11 September 2006

Through reflection on the First International iPED Conference 2006, and its overarching theme of ‘Pedagogical Research and Academic Identities’, this paper considers the achievement of the wider aims of the conference, which were to facilitate dialogue between researchers in order to explore the conference themes collaboratively, and to provide networking opportunities which would enable participants to build alliances. The abstracts for all papers mentioned are available via the conference website www.coventry.ac.uk/iped2006.     

Visualizing strategic change in an educational development centre with product-based analysis

Product-based analysis (PBA) is a new way of modelling the strategic direction of an educational development centre (EDC). It was developed within an English EDC to complement other strategic techniques, providing a means of visualizing the overall strategy. This critique of PBA is set in the context of global university reforms, restructurings and economic constraints that EDCs mirror in miniature. The case for PBA is demonstrated through two exemplars, one retrospective, the other applied to the same group, now dispersed several years on, as it sets out a collaborative strategy to address the future uncertainties shared by many EDCs.     

Strengthening Agricultural Education and Training in sub-Saharan Africa from an Innovation Systems Perspective: A Case Study of Mozambique

Abstract

This paper examines how post-secondary agricultural education and training (AET) in sub-Saharan Africa can contribute to agricultural development by strengthening the capacity to innovate—to introduce new products and processes that are socially or economically relevant to smallholder farmers and other agents. Using the AET system in Mozambique as a case study, this paper examines the role of AET within the context of an agricultural innovation system. This innovation systems perspective offers an analytical framework to examine technological change in agriculture as a complex process of interactions among diverse actors who generate, exchange, and use knowledge, conditioned by complex social and economic institutions. The paper argues that while AET is conventionally viewed as key to the development of human capital, it also has a vital role to play in building the capacity of organizations and individuals to transmit and adapt information, products and processes, and new organizational cultures and behaviors. The paper emphasizes the importance of improving AET systems by strengthening the capabilities of organizations and professionals; changing organizational cultures, behaviors, and incentives; and building innovation networks and linkages. The paper offers several recommendations to enhance the effectiveness of AET for agricultural innovation and development. Key reforms include aligning the mandates of AET organizations with national development aspirations; inducing change in the cultures of AET organizations through the introduction of educational programs and linkages beyond the AET system; and enhancing innovative individual and organizational capacity by improving incentives to forge stronger links between AET and other stakeholders.     

Open-ended Cases in Agroecology: Farming and Food Systems in the Nordic Region and the US Midwest

Abstract

Our aim is to describe open-ended case studies for learning real-life problem solving skills, and relate this approach to conventional, closed-ended decision case studies. Teaching methods are open-ended cases in agroecology, an alternative to traditional strategies that lead students through prepared materials and structured discussions to determine an outcome already known to the instructor. Our method promotes a culture of curiosity. Multiple evaluation criteria show how this learning strategy provides students with practice in researching, envisioning and designing potential scenarios for clients in the field. In agroecology case studies, students and instructors are co-learners in a discovery process that includes gathering information from key clients, interviewing major stakeholders, and building an understanding of the current context of the local farming and food systems. Two agroecology courses in Norway, a field course in the US Midwest, and an experimental course in Sweden and Vietnam illustrate this learning strategy. Student evaluations of learning have been highly positive, and skills and methods from courses have been applied in their thesis projects and professional careers.

Practical results reveal that students are well prepared for an uncertain, complex, multi-dimensional and dynamic future, have the capacity to develop alternative future scenarios, and have practiced methods to evaluate options based on production, economic, environmental and social criteria and impacts. This innovative strategy is offered as a complement or alternative to conventional decision case studies and evaluated as an approach to experiential learning, an important and effective method for adult learners.     

A Longitudinal View of the Liberal Arts Curriculum a Decade After Merger: A Multiple Case Study of Community Colleges in Connecticut,Kentucky, and Louisiana

This study is an examination of the state of the liberal arts curriculum in community colleges in three geographic regions of the United States. From a constructivist paradigm and using globalization theory as a theoretical framework, this multiple case study examined faculty work life and administrative processes related to curriculum change in merged community and technical colleges. Through an examination of research on globalization, mergers, and trends in the general education and liberal arts curriculum, a gap in the literature emerged in the studies of community college curriculums after merger. This study considers whether the focus on workforce development and decrease in the transfer mission has diminished the liberal arts courses in the college curriculum. Research on liberal arts courses identified them as courses that emphasize higher order thinking and the development of intellectual skills needed to engage in a democratic society. If students are not exposed to these skills, it may have a detrimental effect on a democratic society. Study findings suggested that the English and communication curriculums are narrowing and the mission is more toward workforce skill preparation. Also, the changing demographics of today[#x02019]s community college students, as well as the ongoing budget constraints, create challenges and frustrations for faculty members.     

A Social-Justice-Based Resident Assistant (RA) Training Program on a Midsized Rural Community College Campus

Social justice education within the community college setting has not been an academic focus to date; yet, community colleges remain an environment for a diverse student population due to their low cost, open access, and variety of course delivery methods. Rural community colleges, however, may pose an interesting challenge to those wishing to implement social justice initiatives within coursework and existing programs. This article provides an example of a social justice training program that was developed for resident assistants on a midsized, rural community college in the Midwest, with a booming residential student population, and the challenges encountered during the phases of the project. Results of pre- and postassessments with the participants of the training suggest that a quality training program can equip students with the tools needed to feel more confident in their abilities to perform their job well.
