FACTORS ASSOCIATED WITH INJURIES SUSTAINED BY PLAYERS DURING A CURRIE CUP RUGBY COMPETITION.

le Roux, Douglas Leonard 05 July 2005 (has links)
The aim of this study was to review the available literature on the epidemiology of injuries in professional rugby, and then to collect data on previous injuries and the influence of external factors on rugby injuries. Secondly, the incidence, nature and circumstances surrounding injuries in a cohort of professional South African provincial rugby players were documented. The data collected was compared with available data in order to determine trends of injuries that, if taken into consideration, could possibly lead to the prevention of injuries to future rugby players. No study has been done on injury rate and frequency in the Currie Cup competition. Being the cornerstone of providing players for competitions like the Super 12 and Tri-nations, it is certainly appropriate to record the incidence and nature of injuries in the Currie Cup competition. This study attempted to identify factors associated with injury, to direct further analytical research and suggest measures to reduce injury rate. It also drew a comparison between results obtained through this study, and results obtained by other relevant studies in other competitions. The epidemiological data used in this study were collected from two professional rugby teams that competed in the 2002 Currie Cup Rugby Competition. This competition is held annually in South Africa and includes provincial teams from 14 regions in South Africa.

VARIABLES CONTRIBUTING TO SATISFACTION IN WILDLIFE TOURISM

Moreri-Toteng, Amanda B 05 September 2008 (has links)
The study was undertaken to identify and evaluate variables that contribute to wildlife tourist satisfaction. Clark et al. (1999) argue that the hospitality and tourism industries are still relatively under researched. Therefore, this research is particularly important because it focuses on wildlife tourist satisfaction as opposed to customer satisfaction in general. According to Teye and Leclerc (1998), satisfaction is vital for ensuring sustainability of the tourism industry. Similarly, Bramwell (1998) argues that tourist destinations should offer exceptional and satisfying products and services in order to retain and attract more tourists. The study was conducted at the Chobe National Park (CNP), Botswanaâs largest and most popular national park. CNP is popular for its abundant and diverse wild species. Following the arguments on the importance of wildlife tourist satisfaction the study sought to establish how wildlife touristsâ experiences impact on their overall satisfaction. The study also assessed the extent to which Chobe National Park contributes to wildlife tourist satisfaction in relation to the identified variables. The convenience sampling method was applied and the success of the pilot study indicated the usability of the research instrument. The research utilised the SERV-PERVAL scale (Petrick 2000). The scale was developed to assess service quality and perceived value. SERV-PERVAL measures quality as a measure of the supplierâs performance. The measurement of quality is crucial because quality is argued to be the best predictor of perceived value. Data was collected by the use of a structured self-completion questionnaire. The questionnaire was divided into three sections: demographic data, the SERV-PERVAL scale to assess questions on service quality, perceived value and satisfaction. The third section was a combination of a Likert scale and open-ended questions gathering information on expectations and motivations. The descriptive method of analysis, with tables and figures, was applied. The level of significance between variables was determined through the use of the correlation analysis, and the multiple regression model was utilised to investigate the contribution of variables to wildlife tourist satisfaction. The conclusion derived from the literature reviewed is that the concept satisfaction is core in the wildlife tourism industry because it involves feelings of wildlife tourists after experiencing wildlife tourism services. The literature has positively associated and it emphasised the importance of several concepts to wildlife tourist satisfaction. These concepts are: service quality, price and value for money, tourist experience and expectations. While the results of the survey condoned the significance of service quality, price, value for money and tourist experience to wildlife tourist satisfaction, they also indicated and emphasised the importance of wildlife-related variables. These are: safety measures from attack by wild animals, availability and diversity of wild species, condition of vegetation in the wildlife area and accessibility. It is through the use of these variables that wildlife tourists evaluate their experiences and rate their satisfaction levels. Some of the results are, however, in conflict with two arguments found in the literature. Firstly the results contradicted the argument that wildlife tourists assess their satisfaction on the basis of whether or not their initial expectations were met. Some tourists indicated they had a satisfactory experience and yet they did not have prior expectations before they travelled to CNP. As a result, touristsâ expectations were found not to be one of the critical variables that contribute to wildlife tourist satisfaction. Secondly, despite the argument that one benefit of tourist satisfaction is the revisits by satisfied tourists, satisfied wildlife tourists in this study indicated they were satisfied with their experience but would not re-visit CNP, mainly because they had other commitments.

PARENTAL INVOLVEMENT IN SPORT: PERCEPTIONS OF COMPETITIVE ADOLESCENT SWIMMERS

Stroebel, Leoni Catherine Emilie 25 September 2007 (has links)
All adults involved in childrenâs sport affect the nature of the sporting experience, and to a large extent determine whether or not it is a positive experience for children. Of all adults involved, the parents are perhaps the most important and play the most significant role in childrenâs sport. The purpose of this study was to examine how a group of competitive and professionally trained adolescent swimmers perceived parental involvement and how it affected their total sport experience. Participants in the study were 93 (45 male and 48 female) competitive adolescent swimmers between the ages of 13 and 22 years, who received professional coaching for 1 to 15 years, and trained for 5 to 11 months per annum. Respondents completed the parental involvement in sport questionnaire (PISQ). The questionnaire consists of three multi-item scales. The three scales measured Directive behaviour (DB), Active involvement (AI), and Praise and understanding (PU). A single item of Pressure (P) was included as a dependent variable. The questionnaire was designed to elicit responses about the behaviour of parents with regard to their childrenâs swimming activities. Respondents identified the frequency with which certain behaviours were (a) exhibited by, and (b) desired of their parents. Discrepancies between exhibited and desired behaviour indicated the extent of respondentsâ satisfaction with these behaviours. Single sample t-tests showed that respondents perceived insufficient levels of DB, and satisfactory levels of PU, AI and P from their mothers. The results revealed that swimmers perceived satisfactory levels of pressure from their mothers, which leads to the conclusion that they find the amount of pressure acceptable. Single sample t-tests to determine the behaviour of fathers, showed satisfactory levels of DB, which suggests that fathers exhibit an appropriate level of directing or controlling of their childrenâs sporting experience. This is in contrast with the excessive levels of PU, AI and P that the respondents perceive from their fathers. Respondents may feel pressured by disproportionate praise as this might be accompanied by efforts to take control to an unacceptable degree. A second questionnaire was distributed to assess participantsâ enjoyment of their swimming. This questionnaire consists of three questions measuring the enjoyment of sport. The data revealed that the majority of the respondents (92%) were very satisfied with their swimming experience in general and indicated that they enjoyed it to a large extent. The data suggests that the current level of pressure the swimmers experienced did not have any affect on their level of enjoyment. The study indicates that parents who express satisfaction with childrenâs sport performance, who interact positively with them, and who are generally positively involved and supportive in the childrenâs sport experience may enhance the enjoyment they derive from their sport participation. Optimal parental involvement in sport could be achieved by having well-organised, well-run programmes, and by providing parents with an opportunity to receive some education about the sport programmes in which their children are involved. A proposed document, âPractical Guidelines for Swimmersâ Parentsâ, was prepared in order to provide parents with a course of action to maximise their involvement. It is recommended that the above-mentioned document be distributed to the parents of the participants in this study.

Eye movement desensitization and reprocessing (EMDR) : the making of a psychotherapy

Cohen, Steven, 1973- January 2000 (has links)
Eye Movement Desensitization Reprocessing (EMDR) therapy has burst upon the psychotherapeutic scene as a time-limited, cost-contained, and efficacious treatment for anxiety, stress, and psychological trauma. Although this therapy has been pronounced as revolutionary by its inventor, Francine Shapiro, it has distinct historical precedents. The explanatory models of pathogenic memory and dissociation theory, and the reliance on mechanical inference for objectivity make EMDR therapy familiar and salient. Notions of suggestion and hypnosis, and the eye-movement component of therapy are presented as discontinuous with clinical and theoretical practice, in order to free them from the tainting associations of pseudo-science and quackery. By connecting the current EMDR movement with the conceptual and practical history of traumatic memory, dissociation, and suggestion, I argue that EMDR is not revolutionary. It is a powerful technology of the self, normalizing and valourizing certain ways of behaving and thinking. Shapiro's implicit assumptions that psychological suffering is pathological, and that early traumatic events are indelibly encoded, stored and dissociated in the brain are problematized. A brief commentary on the moral, political, and psychotherapeutic implications of EMDR therapy is provided.

Activity and behaviour of Entamoeba histolytica in vitro.

Smith, James Martin. January 1982 (has links)
Using a newly devised model, the in vitro behaviour of E. histolytica strains IP-106, NIH:200 and DKB has been measured. Behavioural differences between the three strains have been demonstrated which correlate with their virulence. Changes in some environmental conditions (e.g. low pH, high concentrations of bile) caused behavioural changes within the strains studied. The type of movement exhibited by trophozoites of E. histolytica have been characterized and the forces produced by a pseudopodium during penetration have been measured. A 'monopodial' form of E. histolytica has been described. This form comprising less than 1% of a normal amoebic population in culture, was found to increase in numbers in the presence of bile and also under conditions of fluctuating temperature. / Iron was found to be a necessary requirement for amoebic growth, having a direct effect on the growth rate of E. histolytica irrespective of the source of the iron (ferric or ferrous). The three strains of E. histolytica investigated exhibited different responses which correlated with their respective virulence.

Religion and nationalism in India : the case of the Punjab, 1960-1990

Deol, Harnik January 1996 (has links)
The research examines the factors which account for the emergence of ethno-nationalist movements in multi-ethnic and late industrialising societies such as India. The research employs a historical sociological approach to the study of nationalism. Opening with an interrogation of the classic theories of nationalism, the research shows the Eurocentric limitations of these works. By providing an account of the distinctive nature and development of Indian nationalism, it is maintained that the nature, growth, timing and scope of nationalist movements is affected by the level of development and the nature of the state and society in which they emerge. Using the theoretical framework developed here, the theses seeks to explain the nature and timing of breakaway movements in the Indian subcontinent. By providing an account of the social composition of the Sikh secessionist movement, the research shifts the focus on to the peasantry. Consequently, the study interrogates the social and cultural sphere beyond the English-speaking Indian elite. The role of the widely influential media, such as the vernacular press and cassettes, in ethnic movements is also considered. The hypothesis is that the conjunction of three sets of factors explain the rise of Sikh nationalism. The first is economic, notably the transition to commercial agriculture, the second is the revolution in communication, notably the expansion of vernacular press and cassettes and the third is religious, notably the revolutionary Sikh religious ideology with emphasis on martyrdom. The theses traces the three stage evolution of the Sikhs from a religious congregation into an ethnic community in the nineteenth century and from an ethnic community into a nation in the twentieth century.
