Comparison of bungee-aided and free-bouncing accelerations on trampoline

Trampolines remain the single best apparatus for the training of aerial acrobatics skills. Trampoline use has led to catastrophic injuries from poor landings. Passive injury prevention countermeasures such as specialized matting have been largely ineffective. Active injury countermeasures such as hand spotting, “throw-in” mats, and overhead spotting rigs provide the most effective methods. The recent addition of several bungee cords between the ropes and the gymnast’s spotting harness has resulted in altered teaching and coaching of trampoline-related acrobatics. Bungee cords have eliminated the need for a coach/spotter to manage the ropes during skill learning. The purpose of this study was to assess the influence of the addition of bungee cords with a traditional rope-based overhead spotting rig. There is a paucity of any research involving trampoline injury countermeasures. Ten experienced trampoline acrobatic athletes (5 males, 5 females) from the U.S. Ski and Snowboard Association Aerials National Team performed 10 bounces as high as they could control. A triaxial accelerometer (200 Hz) characterized 10 bungee cord aided bounces and 10 freebounces on a trampoline from each athlete. Bed contact times, peak accelerations, and average accelerations were obtained. The results supported our hypotheses that the bungeeaided bounces achieved only 40% (average) to 70% (peak) of the free-bouncing accelerations (all ρ 0.092). The bed contact time was approximately 65% longer during the bungee-aided bounces (ρ < 0.001). Bungee cords may reduce the harshness of landings on trampoline

Restructuring reforms in Turkish teacher education: Modernization and development in a dynamic environment

Cataloged from PDF version of article.The paper examines the effectiveness of recent reforms in teacher education in Turkey, specifically the restructuring of programmes in university faculties of education. It first, briefly, sets the reforms of the 1990s in an historical context, prior to the 1997 Act which increased the length of compulsory schooling from 5 to 8 years, and the 1998 restructuring of faculties of education. It considers the national need for the restructuring of teacher education and the issues involved. The thrust of the paper is a study of how teacher educators across the country perceive both the changes and their effect on the quality of teacher education, methodology as a discipline, school partnerships, and relationships with the Ministry of National Education. r 2007 Elsevier Ltd.

Interview Shocks and Shockwaves

This article uses a postmodern lens to examine shocks, cognitive emotional reactions of the interviewer to the unexpected, and shows how shocks and shockwaves, responses to shocks, are related to the process of Othering. The concepts master narrative, coherence, Othering, positionality, and nonunitary subjectivity are used to present the analysis. Using excerpts from research interviews as illustrations, the article describes three types of shocks - those based on a violation of a social taboo, those deriving from professional role reversal, and those that are based on stereotypes. In addition, it explains three types of responses to shock - avoidance, circular strategies, and acceptance and moving on. The article shows how interviewees resist being Othered and, in an attempt to negotiate a more equitable interview situation, administer shocks. Interviewer expectations of master narratives and the process of Othering prevent interviewers from hearing complex, multifaceted, and atypical stories

Developing Educational Groups in Social Work Practice

Education is integral to social work practice with groups and a central component of educational groups. Yet the social work literature has not offered much guidance in the development of educational groups other than to report on the content and/or evaluation of groups that are focused on a specific condition or population. This paper offers a generic process model for educational groups that are developed and led by social workers. The educational groups described here are differentiated from psychoeducational groups, which are treatment-oriented. The paper provides guidelines on how to set up educational groups with particular attention to their structure, content of the curriculum, implementation, and evaluation. Two checklists are offered to assist in the development and implementation and evaluation of educational groups

Teacher education accreditation in Turkey: The creation of a culture of quality

Cataloged from PDF version of article.Turkey’s experience in developing and piloting accreditation criteria and national standards for teacher education is examined. The full implementation of an accreditation process for teacher education programs was not completed within the time of the development project. However, the effort to do so encouraged the formation of a ‘quality culture’ in the faculties of education. The paper discusses what took place and analyses the later response of teacher educators to the introduction of accreditation criteria and the way in which they were introduced. Educators largely welcomed national standards and accreditation, but wished to have flexible means of implementation

Curriculum Reform in Turkish Teacher Education: Attitudes of Teacher Educators towards Change in an EU Candidate Nation

Cataloged from PDF version of article.Educational development is one way through which Turkey enhances progress towards its social goals and prepares itself for European Union membership. A major effort to upgrade the Turkish educational system was made through a multi-phased comprehensive reform of the sector introduced during the 1990s. One part of this reform, perhaps most crucial to the long-term effectiveness of other developments in education, was a transformation of the approach to teacher education. This paper utilizes recently conducted research to assess the nature and extent of that reform as well as identifying the factors which enhanced its effectiveness

Non-Volatile Memory Characteristics of Submicrometre Hall Structures Fabricated in Epitaxial Ferromagnetic MnAl Films on GaAs

Hall-effect structures with submicrometre linewidths (<0.3pm) have been fabricated in ferromagnetic thin films of Mn[sub 0.60]Al[sub 0.40] which are epitaxially grown on a GaAs substrate. The MnAl thin films exhibit a perpendicular remanent magnetisation and an extraordinary Hall effect with square hysteretic behaviour. The presence of two distinct stable readout states demonstrates the potential of using ultrasmall ferromagnetic volumes for electrically addressable, nonvolatile storage of digital information

Utilization of Mental Health Services by Low-Income Pregnant and Postpartum Women on Medical Assistance

This paper examines mental health service use among publicly insured white and African-American pregnant and postpartum women who live in a metropolitan area. The study examines the extent to which ethnicity, physical health problems, and behavioral health risk factors are associated with the probability of service use during the prenatal- postpartum period. It also analyzes the patterns of service utilization for those women who used mental health services. Medicaid claims and eligibility data, County Reporting System claims and admissions data, and Pennsylvania State Vital Birth Records were integrated using a unique algorithm. Logistic regression was employed to estimate the probability of mental health service use among 3,841 low-income women residing in Philadelphia who were continuously enrolled in Medicaid for 9 months preceding delivery and 6 months postpartum. Analyses were also conducted on the intensity and location of service use, as well as psychiatric diagnosis, during pregnancy and the postpartum period. About 10% of the women used mental health services during the study period. Women were more likely to use services if they were Caucasian, had a number of chronic diseases, had a number of pregnancy complications, and smoked. Among users, the same proportion (ca. 6%) used services during pregnancy and postpartum, with the average number of outpatient visits slightly higher during pregnancy than during the postpartum period. Most outpatient services (86%) were delivered in the specialty sector. Most women who used mental health services (84%) were diagnosed with minor psychiatric disorders including minor depression and anxiety disorders. Women who used services during the postpartum only were more likely to be diagnosed with major depression, whereas women who used services throughout the perinatal period were more likely to be diagnosed with severe mental disorders. Health providers can use information generated in this study to identify women who are likely to have a need for mental health services

Gender Differences in the Construction of Spirituality, Work, Learning, and Community by Baalei Teshuvah

This paper explores the question, How do Jewish men and women who have become Orthodox (baalei teshuvah) compare in their constructions of spirituality, work, learning, religious practices, and community? It is based on a qualitative research study that included interviews with 48 baalei teshuvah (24 men, 24 women), two focus groups, and ten key informant interviews. Participants were from the East Coast of the USA. We found the women more affirmative about their spirituality and feelings about community; men identified with these experiences but not the terminology. The men gave more attention to work and to their struggles integrating work and religion. The women expressed excitement about learning whereas the men conveyed self-consciousness over their language and learning deficiencies

Crossing Cultural Barriers in Research Interviewing

This article critically examines a qualitative research interview in which cultural barriers between a white non-Muslim female interviewer and an African American Muslim interviewee, both from the USA, became evident and were overcome within the same interview. This interview and two follow-up interviews are presented as a \u27telling case\u27 about crossing cultural barriers. The analysis focuses on seven phases of the interview (cultural barriers, warming up, crossing the racial barrier, connecting as social workers, connecting as women, connecting as students, and crossing the tape recorder barrier). The discussion outlines the pre-interview and during-interview barriers and facilitating conditions and related implications for cross-cultural qualitative research interviewing
