BALL TRACKING IN FOOTBALL

This study outines the evaluation of VICON TRACKER software in tracking a ball in a large test area. A 22 camera VICON system and VICON Tracker software was used to track a soccer ball both indoor (22 m x 12 m) and outdoor (22 m x 28 m). Different ball marker setups were evaluated for accuracy and percentage data capture manipulating the number and type of reflective markers, as well as software settings, ands whether the system identified the centre of the ball. TRACKER achieved greater than 90% data capture percentage using the half dome markers or nine flat marker setups. Importantly a pre-test setup of the ball object and a 200 Hz (as opposed to 100 Hz) sample rate was needed. The ball centre was also captured by the software. Future work will examine if this system can perform in larger spaces and with multiple players in the area

A critical investigation of the organizational factors affecting the development of local agenda 21 by a local authority

This thesis uses action research to investigate the organizational factors which are affecting the implementation of local agenda 21, and the accompanying necessary internal changes, in a local authority. Following an examination of literature relating to sustainable development and local agenda 21, organizational culture and attempts to change it are identified as the important areas to be investigated. There is an examination of theory in those areas and a two-stage study is carried out. This allows for the first stage study to be assessed and any gaps, where the research questions are not being answered, to be identified and dealt with in the second stage study. It was found that in local authorities there are sub-cultures, and that the split is along departmental lines, which affect the facilitation of sustainable development to differing degrees. Socially based departments had sub-cultures which were less appropriate for sustainable development then environmentally based ones. The local authorities were making changes of a structural and strategic nature, but as regards human processes, it was found that although authorities were concentrating on trying to raise awareness, the strategies they were using for this were ineffective. Two case studies were also conducted, one of a local authority similar in many ways to the one in the main study and the other of a dissimilar one, to assess whether the findings from the main study might be more generally applicable. The findings from these case studies suggested that the findings were generally applicable.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

An Ecological Study of Anterior Cruciate Ligament Reconstruction, Part 1:Clinical Tests Do Not Correlate With Return-to-Sport Outcomes

BACKGROUND: Additional high-quality prospective studies are needed to better define the objective criteria used in relation to return-to-sport decisions after synthetic (ligament advanced reinforcement system [LARS]) and autograft (hamstring tendon [2ST/2GR]) anterior cruciate ligament (ACL) reconstruction in active populations. PURPOSE: To prospectively investigate and describe the recovery of objective clinical outcomes after autograft (2ST/2GR) and synthetic (LARS) ACL reconstructions, as well as to investigate the relationship between these clinimetric test outcomes and return-to-sport activity (Tegner activity scale [TAS] score) at 12 and 24 months postoperatively. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: A total of 64 patients who underwent ACL reconstruction (32 LARS, 32 2ST/2GR autograft) and 32 healthy reference participants were assessed for joint laxity (KT-1000 arthrometer), clinical outcome (2000 International Knee Documentation Committee [IKDC] knee examination), and activity (TAS score) preoperatively and at 12, 16, 20, and 24 weeks and 12 and 24 months postoperatively. RESULTS: There was no significant correlation observed between clinical results using the 2000 IKDC knee examination and TAS score at 24 months (r (s) = 0.188, P = .137), nor were results for side-to-side difference (r (s) = 0.030, P = .814) or absolute KT-1000 arthrometer laxity of the surgical leg at 24 months postoperatively (r (s) = 0.076, P = .553) correlated with return-to-sport activity. Nonetheless, return-to-sport rates within the surgical cohort were 81% at 12 months and 83% at 24 months, respectively. No statistically significant differences were observed between physiological laxity of the uninjured knee within the surgical group compared with healthy knees within the reference group (P = .522). CONCLUSION: The results indicate that although relatively high levels of return-to-sport outcomes were achieved at 24 months compared with those previously reported in the literature, correlations between objective clinical tests and return-to-sport outcomes may not occur. Clinical outcome measures may provide suitable baseline information; however, the results of this study suggest that clinicians may need to place greater emphasis on other outcome measures when seeking to objectively promote safe return to sport

The study of the audit expectations gap in the public sector of Malaysia

The audit expectations gap is a prominent issue in the private sector. However, in the public sector, the audit expectations gap is an emerging issue that has received little attention by reseachers. To date, only a limited number of studies on the audit expectations gap in the public sector are available, either in the context of a financial audit or a performance audit. This study focused on the audit expectations gap in the context of the latter. The importance of the performance audit function in the Malaysian public sector, combined with recent developments related to this type of audit in the country (such as increasing expectations among the users and associated problems in practice) were the reasons for conducting the study in this area. Thus, the study aims to identify the existence of the audit expectations gap in the Malaysian public sector. In achieving this objective, it explores the perceptions of auditors and Public Account Committee (PAC) members, auditees and ‘other users’ (consisting of journalists, politicians and academics). The conceptual framework in this study was developed based on Chowdhury’s (1996) and Porter’s (1993) approaches. Utilising the accountability-based framework as suggested by Chowdhury, six audit concepts (auditor independence, auditor competence, audit scope, auditor ethics, audit reporting and auditing standards) were examined. Porter’s model was subsequently utilised to identify the nature and the components of the gap. This study employed two types of research methods: interviews and audit report analysis. Interviews were conducted with 37 participants comprising of auditors, PAC members, auditees and ‘other users’. The second research method involved the examination of four performance audit reports. The findings of this study indicated that the audit expectations gap exists in the Malaysian public sector in the context of performance auditing. The analysis of interviews and audit reports clearly suggest that the audit expectations gap exists over a number of auditing issues. These comprise fraud detection exercises, the influence of management, executive and other parties on auditors, outsourcing the audit to private audit firms, content and format of the audit report and extending the audit mandate to cover the question of merits of policy.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

Opportunities for utilising DNA-based technologies to enhance traceability and profitability in the Australian Red Meat Industry

The potential role of genomics to further improve traceability levels in the red meat industry was investigated, as DNA-based technologies offer unambiguous identification with a range of auxiliary benefits. Modelling indicated that genotyping the entire national beef herd for traceability is unlikely to compensate for the additional costs involved. However, potential additional benefits (faster genetic gain and better management decisions) make several implementation models appear to be highly attractive. Genotyping the national sheep flock is impractical, but the cost of using DNA judiciously to augment NLIS could be quite cost effective.Perceptions, concerns and experiences around traceability, DNA technologies, costs and willingness to pay were explored through industry consultations. Application of genomic technology for traceability alone was not generally seen as attractive, but the ancillary benefits that accompany lifetime traceability would make the value proposition more attractive.There are instances of DNA already being used to augment traceability and there is a strong argument for taking a proactive approach to coordinating its wider use. The longer the delay, the greater the costs and difficulties arising from fragmentation. A program of work with a series of stop/go decision points is proposed, to be coordinated and overseen by an appropriately-qualified steering group

Further education sector governors as ethnographers: five case studies

This paper considers how governors in the English Further Education and Skills (FE) sector examined their practice as ethnographers. The paper locates both FE governance and ethnography within the challenges of the performative and Panoptic environments facing English education. In doing so, the paper explores how the informants’ mobilisation of ethnographic methods revealed a novel lens on both governance and the role of ethnographer. Employing Grounded Theory, the paper considers how the participants negotiated philosophical questions regarding evidence, objectivity and truth. The paper suggests that despite the deep-seated complexities inherent in conducting ethnography in performative contexts, the participants generated data which painted a unique and revealing picture upon their practice as governor and researcher

Interventions to improve continence for children and young people with neurodisability: a national survey of practitioner and family perspectives and experiences.

Objective Describe families’ experiences of interventions to improve continence in children and young people with neurodisability, and health professionals’ and school and social care staff’s perspectives regarding factors affecting intervention use. Design Four online surveys were developed and advertised to parent carers, young people with neurodisability, health professionals and school and social care staff, via societies, charities, professional contacts, schools, local authorities, and national parent carer and family forums, who shared invitations with their networks. Survey questions explored: difficulties helping children and young people use interventions; acceptability of interventions and waiting times; ease of use and availability of interventions, and facilitators and barriers to improving continence. Results 1028 parent carers, 26 young people, 352 health professionals and 202 school and social care staff registered to participate. Completed surveys were received from 579 (56.3%) parent carers, 20 (77%) young people, 193 (54.8%) health professionals, and 119 (58.9%) school and social care staff. Common parent carer-reported difficulties in using interventions to help their children and young people to learn to use the toilet included their child’s lack of understanding about what was required (reported by 337 of 556 (60.6%) parent carers who completed question) and their child’s lack of willingness (343 of 556, 61.7%). Almost all (142 of 156, 91%) health professionals reported lack of funding and resources as barriers to provision of continence services. Many young people (14 of 19, 74%) were unhappy using toilet facilities while out and about. Conclusions Perceptions that children lack understanding and willingness, and inadequate facilities impact the implementation of toileting interventions for children and young people with neurodisability. Greater understanding is needed for children to learn developmentally appropriate toileting skills. Further research is recommended around availability and acceptability of interventions to ensure quality of life is unaffected
