Title: Postural stability assesment of female physiotherapists Objectives: The aim of this thesis is to evaluate and compare the level of dynamic postural stability of female physiotherapists with former or current sports (racing) careers versus physiotherapists without sports careers. Another aim is to compare how the level of postural stability of physiotherapists differs from the general population. Methods: This study is among quantitative experimental studies. The research was done from August 2020 to February 2021. The research involved 20 probands - women. Participants were divided into two groups by ten based on a former or current sports career or without a sports career. The control group was provided with normative data from the instrument manufacturer. The analysis and information on sports activities were collected using a questionnaire. Postural stability was measured with The Neurocom's The EquiTest Smart. The following tests were used: The Sensory Organization Test, The Motor Control Test, The Adaption Test, and The Limits of Stability Test. The results were processed with tables in Microsoft Excel. In Microsoft Excel, data were evaluated statistically and compared with each other. The mean, standard deviation, median and interquartile range were calculated. The following...

Yes / Background: Interpreting evaluations of complex interventions can be difficult without sufficient description of key intervention content. We aimed to develop an implementation package for primary care which could be delivered using typically available resources and could be adapted to target determinants of behaviour for each of four quality indicators: diabetes control, blood pressure control, anticoagulation for atrial fibrillation and risky prescribing. We describe the development and prospective verification of behaviour change techniques (BCTs) embedded within the adaptable implementation packages. Methods: We used an over-lapping multi-staged process. We identified evidence-based, candidate delivery mechanisms—mainly audit and feedback, educational outreach and computerised prompts and reminders. We drew upon interviews with primary care professionals using the Theoretical Domains Framework to explore likely determinants of adherence to quality indicators. We linked determinants to candidate BCTs. With input from stakeholder panels, we prioritised likely determinants and intervention content prior to piloting the implementation packages. Our content analysis assessed the extent to which embedded BCTs could be identified within the packages and compared them across the delivery mechanisms and four quality indicators. Results: Each implementation package included at least 27 out of 30 potentially applicable BCTs representing 15 of 16 BCT categories. Whilst 23 BCTs were shared across all four implementation packages (e.g. BCTs relating to feedback and comparing behaviour), some BCTs were unique to certain delivery mechanisms (e.g. ‘graded tasks’ and ‘problem solving’ for educational outreach). BCTs addressing the determinants ‘environmental context’ and ‘social and professional roles’ (e.g. ‘restructuring the social and ‘physical environment’ and ‘adding objects to the environment’) were indicator specific. We found it challenging to operationalise BCTs targeting ‘environmental context’, ‘social influences’ and ‘social and professional roles’ within our chosen delivery mechanisms. Conclusion: We have demonstrated a transparent process for selecting, operationalising and verifying the BCT content in implementation packages adapted to target four quality indicators in primary care. There was considerable overlap in BCTs identified across the four indicators suggesting core BCTs can be embedded and verified within delivery mechanisms commonly available to primary care. Whilst feedback reports can include a wide range of BCTs, computerised prompts can deliver BCTs at the time of decision making, and educational outreach can allow for flexibility and individual tailoring in delivery / UK National Institute for Health Research (NIHR) under its Programme Grants for Applied Research scheme (Grant Reference Number RP-PG-1209-10040).

Computerised Cognitive Behavioural Therapy (CCBT) has been recommended for patients in the National Health Service (NHS) Primary Care across the United Kingdom for management of mild to moderate anxiety and depression. This approach also promises financial savings, and may fill the gap between demand and supply of face-to-face therapy. Studies have shown that CCBT is feasible and effective. However, dropout rates can be as high as 86%, but the reasons remain unclear and the information available is limited. This thesis explores factors that may impact on the usability and user experience of this computer-mediated therapy. Espousing the “real world” research philosophy and widely used methods in the Human-Computer Interaction (HCI) field for usability evaluations, four studies using a mixed-methods design were conducted. Study I was an online usability survey, which investigated if usability evaluations had been conducted for CCBT applications. Two versions of questionnaires were sent to four CCBT software developers and ten authors of randomised controlled trials. The categories and responses of the questionnaires gathered from five respondents were reviewed and summarised. The findings suggested that usability evaluations for CCBT were still in their infancy when compared to other healthcare interventions to which HCI approaches have been widely applied. Study II was a usability Heuristic Evaluation (HE) conducted with four expert evaluators to assess two different CCBT applications’ interfaces (MoodGYM and Living Life to the Full) against the self-designed usability heuristics for their compliance. The findings revealed numerous usability issues. Major problems related to navigation and inconsistency of the interfaces were identified. These could be rectified to enhance the user experience. Study III focused on other factors besides usability that might have an influence on the effective use of CCBT. Perceptions of service providers who were involved in both decision-making about CCBT availability and supporting its use were gathered. Nine service providers at different NHS organisations were interviewed. The interviews were analysed using techniques from Grounded Theory (GT). The findings suggested that the practitioners’ attitudes towards CCBT might have affected its service delivery. Four categories from the data analysis were identified: (1) shaping behaviour, (2) implementing and delivering, (3) making an appropriate referral, and (4) technology/CCBT packages - advancing with time. A conceptual model was also generated, “building support around CCBT”: a road-map that could address some of these issues. Study IV examined patients’ perceptions and acceptance of a CCBT application (Beating the Blues), its usability and the user experience, and also whether the user characteristics (e.g. computer experience (CE) and computer self-efficacy (CSE)) had any influence on patients’ use of this technology. A mixed-methods approach was utilised with a sample of 33 participants. Face-to-face and email interviews were conducted. Feedback was also gathered from a usability questionnaire and think-aloud protocol with seven participants selected from the sample. The data were analysed using Thematic and Saliency Analysis to uncover themes. Descriptive statistics were used to describe data from questionnaires. Two overarching themes from the interviews were identified: (1) access to CCBT services, and (2) perceptions and attitudes towards CCBT. Both themes revealed issues which might have significantly impacted on patients’ engagement with CCBT. Numerous flaws were also discovered in the application’s design and functionality (e.g. navigation, aesthetics, relevance of content, and inflexibility). However, the results from CE and CSE questionnaires suggested that participants were confident in using this technology. The four studies provided an in-depth understanding of factors that affect the usability and user experience of CCBT and possible reasons for the high attrition rates. The implications of this research point to the need for health policymakers to focus on the current implementation issues and on how best to deploy this treatment therapy to patients. Further development of CCBT is pivotal to its success, in particular, expanding contexts of use and increasing usability evaluations. Keeping users interested and engaged will improve treatment efficiency, completion rates and will achieve better clinical outcomes.

Maintenance is one area of business that recently has been considered as an activity contributing efficiently to the companies' strategic goals. Understanding the way maintenance could utilise modern technology such as computerised tools or digital data processing is one way to make maintenance profitable. Current research lack appropriate methods for determining data and IT requirements, as well as understanding the way IT could be utilised for enhancing maintenance profitability. This thesis studies and develops tools, methods and theories of how information technology can be utilised for maintenance management in order to reach profitable maintenance. The main research problem is therefore: What are the demands on information technology systems to achieve profitable maintenance? The main problem has been divided into three research questions: RQ1) What are the demands on data and information technology systems for strategic management of maintenance?, RQ2) How can we identify relevant data and information technology systems required to achieve cost-effective maintenance decisions? and RQ3) How can we describe the utilisation of information technology within maintenance? This thesis is based on a systems theory approach, where maintenance is not seen as an isolated activity, but something that interacts, affects and is affected by several other activities, such as production, logistic and quality. Several methods have been used for answering the research questions, but the theory-testing case study method dominates. Main results achieved in the thesis are models and theory for 1) creating a relevant set of data for cost-effective mainte-nance decisions, 2) monitoring the performance of maintenance, suggest invest-ment possibilities and show maintenance contribution on company strategic level, 3) identifying IT systems requirements demanded to achieve profitable maintenance and 4) assessing the IT maturity of a maintenance organisation for the effective utilisation of IT systems. As an illustrative example of computerised maintenance management demands a conceptual decision support model has been developed, which aims at filling the gaps of poor IT coverage for strategic maintenance decision-making. This thesis concludes that the demands of data and IT applications must be connected to the overall maintenance demands, which are reflected in the maintenance goals, purposes and strategy, in order to achieve profitable maintenance. Furthermore, structured methods that ensure the connection between maintenance business goals and data or IT demands are of importance. The ability to make use if IT within maintenance is reflected in the relative IT maturity of the maintenance organisation. Being able to define the IT maturity allows for choosing the most appropriate IT tool to invest in, so that current and future needs of IT support are also covered for with maximum benefit and minimum cost.

Selection and selection procedures play a key role in the ability of organisations to compete successfully in the complex global and local environment. South Africa is experiencing a serious artisinal and technical skill shortage. Given the unemployment issues and the quest for people to fill the skill shortage gap it is important for organizations to find possible solutions to ensure that they stay competitive and effective in the labour market. Research suggests that at least 12 500 artisans need to be produced each year from 2006 to 2010 to meet the demand for skilled workers. To address above mentioned challenge organizations have to develop strategies to assist them to select individuals with the best chance to succeed in training. Unfortunately, the solution is not simple as organisations have a multitude of influences and pressures which affect their decisions regarding selection procedures. Selection of individuals is becoming an increasingly complex science as organisations have to select a capable and representative workforce. They must thus select candidates that are most likely to benefit from what is offered educationally, meet the requirements stipulated in South Africa's Labour legislation, and will perform most successfully in the specific trade. Bad practice can lead to costly litigation. The objectives of this mini-dissertation were to assess the empirical validity of the Technical Test Battery (TTB), as ability test and the Learning Potential Computerised Adaptive Test (LPCAT) as learning potential test as predictors of academic success of first year apprentice electrician students at a South African technical college serving a mining community. The study explored the current local employment issues that affect selection for training in the technical fields. The difference between the measurement of cognitive ability and learning potential were examined and the nature of the constructs of cognitive ability and that of learning potential were discussed. In the empirical study one of the objectives was to determine whether there was a relationship between the TTB and the LPCAT as two different predictors of the academic success of first yar apprentice electrician students. The difference in the empirical (predictive) validity of the two psychometric selection instruments, if only one of the tests as opposed to if both were used in combination, were examined. Another objective was to determine if there were any differences regarding the scores on the TTB and LPCAT of students from the designated group as opposed to that of students from non-designated groups. Finally this study explored whether the TTB and LPCAT were valid predictors to be used as selection instruments for apprentice electrician students in the South African context The research method consisted of a literature review and an empirical study. The empirical validity of the two predictor tests was validated in terms of the accuracy with which the selection instruments predicted the students' future performance. This research can be categorized as descriptive quantitative research. The TTB and LPCAT scores of a sample of 89 selected apprentice electricians were compared with the number of attempts they used to pass a phase test. Data was analysed by means of descriptive statistics. Pearsons Product Moment Correlation Coefficient, t-tests, ANOVAs as well as discriminant analysis were also used to reach the research objective. Statistically significant relationships were found between the predictor and criterion variables. The results confirm that the TTB and LPCAT are indeed empirical valid tests that can be used in the selection of apprentice electricians. / Thesis (M.A. (Industrial Psychology))--North-West University, Potchefstroom Campus, 2008.

The aim of this research was (1) to provide empirical data of learning potential and English language proficiency for work performance; (2) to establish whether race and gender influence work performance; (3) to evaluate practical utility and to propose recommendations for selection purposes. The Learning Potential Computerised Adaptive Test and the English Literacy Skills Assessment were used as measuring instruments to measure learning potential and English language proficiency respectively. Work performance data were obtained from the normal performance data system of the company where the research was conducted. ANOVA results showed differences between race and gender groupings. A regression analysis confirmed the predictive validity of learning potential and English language proficiency on work performance. The Spearman rho correlation coefficient (p < 0.05) showed a significant positive correlation between the investigated variables / Industrial & Organisational Psychology / M. A.

Existing travel patterns in Windhoek are influenced by the past land use policy of restricted urban development in the former townships ofKatutura and Khomasdal. Thus residents in these townships are faced with longer distances to reach quality urban servtces. This thesis examined the impact on travel demand of changes in land use policies aimed at stimulating growth in the two areas using the HLFM computer model. The results showed that, policy induced land use changes may stimulate population and employment growth in the neglected areas, but with no effects on the present travel patterns. The model needs to be refined to fit the peculiarity of the study area. Nevertheless, information provided in the thesis could be used in assessing areas where development trends will go if any ofthe land use policy tested in the study is adopted. / Geography / M.A. (Geography)

Dissertation submitted in partial compliance with the requirements for the Masters’ Degree in Technology: Chiropractic, Durban University of Technology, 2013. / Background : Core strengthening may improve athletic ability by providing stability to the trunk, and as a result, stabilising the pelvis. The leverage from which cyclists generate power may be enhanced as a result of a stable pelvis, thereby improving the cyclist’s performance. In the popular, highly competitive sport of cycling, performance enhancement is much sought after. Despite its widespread use, research involving core strengthening in sporting situations is lacking, with studies investigating the effect of a core strengthening programme on cycling performance yet to be investigated. Objectives : To determine the participants’ cycling speed, power, cadence and completion time, and core strength in terms of objective findings, pre- and post- core strengthening intervention, in the whole sample and within the two age strata. To determine the participants’ heart rate in terms of objective findings, and the rate of perceived exertion in terms of subjective findings, pre- and post- core strengthening intervention, in the whole sample and within the two age strata. To determine the participants’ perception of change in speed, power and cadence post- intervention, in the whole sample and within the two age strata. Method : Forty-two asymptomatic cyclists performed two 1.5 km time trials, pre- and post- core strengthening intervention. Core strength assessments were performed pre- and post- intervention, using the Pressure Biofeedback Unit, and the maximum and average speed (km/hr), power (w) and cadence (rpm), and completion time (s) were recorded pre- and post- intervention, using the Computerised Electromagnetic Roller resistance Ergometer (Tacx Trainer). Heart rate and rate of perceived exertion (RPE) were recorded pre- and post- intervention, as well as the participant’s perception of change in speed, power, and cadence post- intervention. SPSS version 20 (SPSS Inc) was used to analyse the data, in the whole sample and stratified into two age strata. Results : ll cycling performance indicators, speed, power, cadence and completion time showed a significant improvement post- intervention, in the whole sample, and within the two age strata. Core strength indicators showed a significant improvement post- intervention, in the whole sample and within the two age strata. A significant decrease in rate of perceived exertion and corresponding heart rate measurements post- intervention was observed in the whole sample. Similarly, the younger age strata reflected a significant decrease in rate of perceived exertion, however heart rate measurements were not significant. In contrast, the older age strata showed significant changes in heart rate measurements, with no significance in rate of perceived exertion measurements. The majority of participants experienced an increased perception in all outcomes post- intervention. Conclusions: The results of this study found that core strengthening had a statistically significant effect (p < 0.001) on cycling performance, both in terms of objective and subjective findings. Future studies could address the effect of core strengthening in an endurance setting.
