A research project submitted in partial fulfilment of the requirements for the degree of Master’s (Industrial/Organisational Psychology) in the Faculty of Humanities, University of the Witwatersrand, Johannesburg, March 2017 / A South African study, based on a sample of 208 medical personnel working in public and private institutions, was conducted in order to determine whether job demands and job resources led to differences in the propensity to comply with Needlestick Injury (NSI) intervention scores. Three self-report questionnaires were completed by the participants, namely the self-developed demographic questionnaire, the Job Demands-Resources Scale (JDRS) which measured job demands and resources, and thirdly the self-developed Propensity to Comply with Interventions for Needlestick Injuries Scale (PCINS) which measured the propensity to comply with interventions for NSIs. Accidental needle stick, as well as sharp, injuries occur frequently within the medical context and are associated with high risks for blood-borne infections (Adefolalu, 2014). Specifically within South Africa blood-borne infections such as HIV carry heavy significance. Needlestick injuries often go unreported by healthcare professionals, and these injuries are widely prevalent. The researcher aimed to explore the job demands and resources that contribute to and mitigate against these injuries. Therefore support for the analysis of job demands and resources and the propensity to comply with NSI interventions exists. The results of the study suggested that there were mostly no significant differences between Job Demands and Resources and the propensity to comply with NSI Interventions scores. However significant relationships were found between length of shift and the propensity to comply with NSI interventions and growth opportunities and the propensity to comply with NSI interventions. The findings did not follow the proposed hypotheses that job demands would lead to a decrease in the propensity to comply with NSI interventions and job resources would lead to an increase in the propensity to comply with NSI interventions as longer length of shift (job demand) led to an increase in propensity to comply with NSI interventions and an association between high levels of growth opportunity (job resource), and low levels of propensity to comply with NSI interventions, was found. / GR2018

Despite a myriad of studies on fall prevention, patient falls continue to be a longterm problem experienced by health care organisations world-wide. Falls impose a heavy burden in terms of social, medical, and financial outcomes, and continue to pose a threat to patient safety. Because the potential for a fall is a constant clinical safety issue in every health care organisation, protecting the patient from falls and subsequent injuries, and ensuring that the patient care environment facilitates, are fundamental aspects in providing quality care. Moreover, the current international focus on creating a culture of quality care and patient safety requires the implementation of fall prevention programs that decrease the risk of falls. As with other international health care organisations, the National University Hospital (where the principal investigator is working), has been challenged with the issue of how to prioritise and implement quality initiatives across all disciplines. Faced with persistent patient falls that affect care outcomes, fall prevention has been a priority initiative at the hospital since 2003. In response, a nursing task force was established in an attempt to resolve this problem. A root cause analysis undertaken by this task force revealed that the hospital protocol on fall prevention was outdated and not evidence-based. Furthermore, many nurses did not understand the importance of fall prevention, while the administration of the fall prevention program was instituted on an ad hoc basis rather than as a standard of care for all patients. The challenge for this task force, as with other health care professionals, was not only in finding an intervention that was effective, but also identifying who would benefit from its implementation. Although the need to apply current best practices to reduce patient falls is clear from the task force results, evidence of the effectiveness of fall prevention interventions in acute care hospitals is lacking in literature. In addition, there are no published studies on fall prevention in Singapore to support changes in nursing practices. Thus, it becomes apparent that research on fall prevention is greatly needed in Singapore so that an evidence-based fall prevention program can be developed. This topic coincides with the Doctor of Nursing course, which requires the student to gain knowledge through scholarly research on contemporary issues in nursing by undertaking two separate projects related to a single area of interest. Undertaking the two research projects on fall prevention in an acute care inpatient hospital as part of the doctoral studies provided an opportunity to address this deficit in a way that could raise awareness of the importance of fall prevention in Singapore hospitals. This research also provides a platform for the first body of research into fall prevention to be conducted within the Singapore health care environment, which is essential, as international studies are not always necessarily applicable to the Singapore context due to differences in educational preparation, skills-mix, organisational culture and nursing practices. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1321300 / Thesis (D.Nurs.) -- University of Adelaide, School of Population Health and Clinical Practice, 2008

Road traffic safety has been a subject of worldwide concern. Dedicated short range communications (DSRC) is widely regarded as a promising enabling technology for collaborative safety applications (CSA), which can provide robust communication and affordable performance to build large scale CSA system. The main focus of this thesis is to develop solutions for DSRC QoS control in order to provide robust QoS support for CSA. The first design objective is to ensure robust and reliable message delivery services for safety applications from the DSRC networks. As the spectrum resources allocated to DSRC network are expected to be shared by both safety and non-safety applications, the second design objective is to make QoS control schemes bandwidth-efficient in order to leave as much as possible bandwidth for non-safety applications. The first part of the thesis investigates QoS control in infrastructure based DSRC networks, where roadside access points (AP) are available to control QoS control at road intersections. After analyse DSRC network capabilities on QoS provisioning without congestion control, we propose a two-phases adaptive QoS control method for DSRC vehicle networks. In the first phase an offline simulation based approach is used to and out the best possible system configurations (e.g. message rate and transmit power) with given numbers of vehicles and QoS requirements. It is noted that with different utility functions the values of optimal parameters proposed by the two phases centralized QoS control scheme will be different. The conclusions obtained with the proposed scheme are dependent on the chosen utility functions. But the proposed two phases centralized QoS control scheme is general and is applicable to different utility functions. In the second phase, these configurations are used online by roadside AP adaptively according to dynamic traffic loads. The second part of the thesis is focused on distributed QoS control for DSRC networks. A framework of collaborative QoS control is proposed, following which we utilize the local channel busy time as the indicator of network congestion and adaptively adjust safety message rate by a modified additive increase and multiplicative decrease (AIMD) method in a distributed way. Numerical results demonstrate the effectiveness of the proposed QoS control schemes.

M.Ing. / Safety within the mining industry is a primary concern for everyone involved. More specifically, active below-ground stope support for South African Mines is becoming increasingly important due to a renewed emphasis on the safety and well-being of the people actually working underground. It is imperative that all stope support systems are rigorously tested, continuously, both under laboratory conditions and in-situ to prove their performance and manufacturing standards. The Rocprop was initially manufactured in 1995 with the first two hundred props being installed at East Driefontein Consolidated Gold Mine in the Carletonville area. In the three years since the first introduction over three hundred thousand Rocprops have been manufactured and sold to South African Mines with the number steadily increasing. The Rocprop is a tubular support consisting of two tubes — a Ø139mm 'inner' tube and a Ø152mm 'outer' tube. One end of each tube is sealed by dome ends which are welded onto the tube mouths. The two tubes, cut to identical lengths, fit inside one another and extend telescopically during installation. Once the desired height has been reached, leaving enough tube overlapping to ensure the support does not buckle, the wedge is hammered in locking the prop at that height. The water is then removed after which the prop will provide active support of the rock mass above it. One of the components responsible for the Rocprops success is a dome end. This is either a forging or a pressing welded onto each end of the support and allows continual concentric loading throughout the life of the Rocprop. At present the dome ends are pressings, manufactured into hemispheres from 10mm mild steel plate in one action. The reason for the Rocprop's success is its performance characteristics. It's all metal construction, ease of installation, reliability and predictability in both seismic and static conditions, fire resistance, blast resistant, economically viability and versatility have made the prop successful. Reasons for the research were to investigate the dome end forming process in general and to investigate current numerical analysis techniques ability to predict loads during manufacture, the final shape, spring-back and other local deformation areas. Also to investigate alternate manufacturing methods such as cold forming, which provides advantages such as better mechanical properties and higher structural capabilities. The use of alternate materials in the Rocprop manufacture has been an ongoing process for MSP, manufacturer and current licensee holder of the Rocprop. A substitute for the current dome end manufactured from mild steel was investigated. For the substitute to be viable the material should be stronger, weigh less and be cost effective. In depth knowledge about the forming of the dome end at various velocities was gathered, providing information for further optimisation of the component.

Abstracts in English, Zulu, Sesotho and Venda / This study focused on occupational health and safety in South African small businesses. The owners/managers of small businesses have a moral, legal and financial obligation to ensure the health and safety of their employees. Both an international and South African perspective on occupational health and safety in small businesses are included in the literature study. Twelve core occupational health and safety criteria, developed specifically with regard to small businesses, were identified and used as basis for this study, in conjunction with the aspects of the theory of planned behaviour. The research design of this study included a positivistic research philosophy and a deductive research approach. A questionnaire was developed and used to determine the knowledge, attitude, behavioural intent and actual behaviour of South African small business owners/managers with regard to occupational health and safety in their businesses. In addition, barriers to occupational health and safety compliance were determined and tested to determine the perceived strength of these barriers. South African small business owners/managers completed the questionnaire for this study. It was determined that the knowledge, attitude, behavioural intent and actual behaviour of South African small business owners/managers related to occupational health and safety were not at optimum levels. Barriers to compliance should be reduced. Legal compliance issues comprise one of the main reasons why South African small businesses fail. Therefore, this study proposes a compliance management framework, based on applicable occupational health and safety legislation that encompasses moral, legal and financial contentions. The identified core occupational health and safety criteria were used as sections in the compliance management framework. This proposed compliance management framework aims to reduce the complexity of occupational health and safety legislation for South African small business owners/managers. / Ngudo heyi yo sedza kha tsireledzo na mutakalo mushumoni kha mabindu maṱuku Afrika Tshipembe.

Thesis (M.Med. (Diagnostic Radiology)) -- University of Limpopo, 2022 / BACKGROUND: Ionizing radiation is detrimental to growing cells. The potential risk of any dose of radiation in growing cells can lead to permanent damage of basic cellular structure resulting in a high risk of developing cancer in children. Therefore, paediatric doctors need sufficient knowledge to protect their patients from late effects of radiation resulting from medical use. Most studies report poor knowledge of radiation safety measures among doctors. PURPOSE: The purpose of this study is to assess the knowledge of radiation safety and radiation doses among paediatric doctors in Pietersburg and Mankweng Hospitals, Limpopo province, South Africa. OBJECTIVE: To assess the paediatric doctors’ knowledge of radiation doses used in radiological diagnostic imaging examinations, as well as their knowledge of radiation safety measures. METHODOLOGY: This is a survey of paediatric doctors in the paediatrics general ward, paediatric oncology, intensive care and neonatal units, and paediatric surgery department, at Pietersburg and Mankweng Hospitals. A self-administered questionnaire with 23 items on knowledge of radiation safety and radiation doses emitted during normal radiological examinations is used to collect the data in May 2021. Data are analysed using Statistical Package for Social Sciences (SSPS) version 26.0 software. Chi-squared test is used to analyse the relationship between variables. Analysis of variance (ANOVA) is used to analyse the differences between variables. A p value of <0.05 is considered statistically significant. A total score of 50% in each section is used to denote adequate knowledge. The result are presented in charts and tables. RESULTS: Out of 52 paediatric doctors, 47 completed the questionnaire achieving a 90.4% response rate. Majority of participants were females (n = 31; 66%). Overall, only 10 (21.2%) of the participants scored 50% and above, including three consultants, two registrars, two medical officers and one medical officer intern. Twenty-five (53.1%) participants scored 50% and above on knowledge of radiation safety. Nearly half (44.7%) of the doctors were familiar with the concept of ALARA principle in radiation dose optimisation. Three participants scored more than 50% in the knowledge of radiation doses section. Only five (10.6%) and 17 (36%) participants correctly identified MRI and ultrasound, respectively, as the radiological diagnostic modalities that do not utilize ionizing radiation. CONCUSION: The level of knowledge of radiation safety and radiation doses among the paediatric doctors are poor. A very small number of the paediatric doctors were able to identify non-ionizing radiation modalities that can be used as an alternative to reduce radiation exposure to paediatrics during radiological investigations. Paediatric doctors will benefit from courses on radiation safety and radiation doses to improve their knowledge and/or eliminate unwarranted exposure of their patients to ionizing radiation.

The purpose of this study was to evaluate the effectiveness of video monitoring devices (VMDs) in reducing incidents of student misbehavior on middle school buses. It was hypothesized that the presence of VMDs would decrease the frequency of behavioral problems encountered by school bus drivers, decrease the number of discipline referrals issued by the drivers, and improve the drivers’ perception of student behavior. The study utilized an experimental design with random assignment of drivers to treatment and control groups. These groups were formed from a population of 282 drivers who serve ten middle schools for Virginia Beach City Public Schools. In the summer of 1993, through a randomization procedure, VMDs were installed on 100 school buses to form the treatment group. The remaining 182 school buses did not receive installation and were designated as the control group. All drivers maintained a daily log of the number of discipline problems encountered on their routes for three 15-day intervals. Statistical analysis revealed a significantly lower number of problems in the treatment group. Secondary analysis indicated that the use of VMDs was ineffective on morning routes but effective on afternoon routes. Also, there was a significantly lower number of discipline problems in the treatment group regardless of the day of the week. As the drivers established rapport and control, both groups experienced a decline in the number of discipline problems throughout the experiment. The treatment group, however, recorded a significantly lower number of problems during each of the three 15-day intervals. This indicates that the students did not become desensitized to the presence of the VMD’s over the five-month experiment. At the conclusion of the study, drivers in the treatment group rated the behavior of their students more highly than the rating of students by drivers in the control group. A tally of the number of discipline referrals issued by the drivers revealed that the members of the treatment group experienced fewer severe disciplinary problems. Finally, multiple regression indicated that of all independent variables, group membership is the best predictor of a number of behavioral problems, discipline referrals issued, and driver perception of student behavior. / Ed.

Background: The aim of this study was to investigate the use and management of hazardous chemical substances (HCS) at a chemistry department in a selected Higher Education Institution in Gauteng province. Method: A quantitative, baseline descriptive study was conducted using a structured survey checklist. The population consisted of the chemistry department. Other than purposive observation by the researcher, employees present during data collection were approached for further clarifying comment to survey questions. Results: It emerged that physical-, health- and environmental hazard classes of HCS were present; and that hazard types included flammable liquids, HCS with acute toxicity and carcinogenicity. Selected exposure control measures were lacking which created risks of fire and explosion. Conclusion: The study reflected the use and management of HCS, the actual and potential human exposure and the exposure control measures. Varying degrees of compliance were found, which, if attended to, should mitigate risks to health and safety. / Health Studies / M.A. (Nursing Science)

The safety at half-signalized intersections in Portland, Oregon is analyzed in this thesis using 10 years of crash history and analysis of video that was collected at a subset of intersections. A half-signalized intersection has a standard red-yellow-green traffic signal for automobiles on the major road, a stop sign for motorists on the minor road, and a pedestrian signal with actuation for pedestrians and/or bicyclists on the minor road. Although prevalent in Canada, this type of intersection control is not typically found in the United States because the MUTCD explicitly prohibits its use. Half-signal use is limited mostly to two cities in the Pacific Northwest. In Portland, Oregon there are forty-seven intersections where half-signals are used but the last installation was in 1986; Seattle has over 100 intersections with half-signals and installs these in new locations where warranted. To explore the safety records of these intersections in Portland, crash data from 2002-2011 was analyzed. A total of 442 crashes over the ten-year period at half-signals were observed. Sixteen of these 442 crashes involved pedestrians. In the crashes involving pedestrians, significant differences were found between the approach street of the vehicle and whether the pedestrian or driver was at fault. In the crash error reports, it was found that significantly more of the crashes involving pedestrians were the fault of motorists departing from the minor road who collided with pedestrians crossing the major street. Further crash analysis at half-signals was performed by developing matched comparison groups of minor stop controlled and fully signalized intersections. Crash rates were 0.158 and 0.178 crashes per million entering vehicles for 3-leg and 4-leg half-signals and these rates did not differ significantly from the minor street stop controlled and signalized comparison groups. Results from the matched comparison showed that the half-signalized group had more rear-end crashes when compared with the minor stop controlled group. This was the only result that held significance when crash rates were considered. It was also observed that the minor stop controlled group had a higher proportion of angle crashes when compared with the half-signal group but this did not influence the crash severity. Pedestrian crashes were more prevalent in the half-signal group when compared with the fully-signalized group. Pedestrian volumes were not available which would be used to determine if this significant measure is a result of higher pedestrian use at half-signals. In addition to crash analysis, video was captured at five half-signalized intersections totaling 180 hours. Traffic volumes, pedestrian and bicycle volumes, and signal actuations were collected over a twenty-four hour period. Over this twenty-four hour period the five intersections averaged daily counts of 18613 vehicles on the major street, 591 vehicles on the minor street, 263 pedestrians crossing the major street, 285 pedestrians crossing the minor street, 52 bicycles on the major street, 37 bicycles on the minor street, and 126 signal actuations. Twenty-four hour observations from each of the intersections were used to study conflicts and compliance. No conflicts were observed that reflect the left-turning from the minor street pedestrian crashes that were identified in the crash history. Compliance of the half-signal by vehicles and pedestrians was comparable to compliance at fully-signalized intersections found in other studies with one exception. Across the intersections where video was collected, consisting of four 4-leg intersections and one 3-leg intersection, seven left turn on red violations were observed which had a significant impact on the time after red that red light violations were made. It is hypothesized that at half-signals vehicles on the major street make a left turn on the red signal very late into the red phase because there is not a risk of colliding with a vehicle traveling on the minor street since traffic volumes on the minor street are comparably low. The observed left turn on red violations did not put pedestrians at risk since by that point into the signal pedestrians were already clear of the intersection. Finally, a stop compliance logistic regression model was developed at four four-leg intersections to see what factors had an effect on minor street vehicle stop compliance. All 166 hours of video were used to observe vehicles that arrived at the half-signal during the pedestrian phase. The dependent variable collected was whether a vehicle came to an acceptable stop. Independent variables collected included the vehicle's queue position, if it was the peak school period, if there was a vehicle across the street on the minor road, if a vehicle was stopped at the signal on the major street, if a pedestrian was present when the vehicle arrived, and the movement that the vehicle made from the minor street. Independent variables used in the model included the vehicle's queue position, if a vehicle was stopped at the signal on the major street, if a pedestrian was present, and if the vehicle made a right turn at the signal. Pedestrian presence and right turning vehicles had a positive impact on stop compliance. Vehicles being further back in the queue and cars stopped at the signal on the major street had a negative impact on stop sign compliance. In the model, pedestrian presence had the largest positive impact on stop compliance. When pedestrians were present, a motorist on the minor street was four times more likely to stop at the sign.
