Quality assurance related to secondary education in the Kingdom of Bahrain

Almadani, Khaled Ahmed January 2012 (has links)
Quality assurance in schools and in higher education has been a growth industry for many years, with all kinds of agencies being funded. With apparently endless growth in education at all levels, with insistent demands on more resources, the political pressures in ensuring value for money have increased. This study explores the perceptions of teachers, students and senior administrators ofquality assurance in secondary schools (ages about 15-18 in Bahrain) in the Kingdom of Bahrain. Here, there is an established system of quality assurance but there is a general feeling of unrest that all is not well in the way quality assurance has developed.The overall aim is to enhance quality assurance in Bahrain, based on sound pedagogical evidence. This study provides an overview of quality assurance in secondary schools in Bahrain with the teachers, students and senior staff. This aims to look at the way secondary education is offered in Bahrain, to explore possible ways to enhance educational provision and, where possible, to look for any evidence that Quality Assurance has improved quality.This study has aimed to gain an overall view of what is happening in secondary education in Bahrain and to identify areas which need further attention. The approach has been very much focussed on the learner.The first experiment seeks to find out how some key stakeholders see present provision in secondary education (ages 15-18) in Bahrain. The aim is to gain an overview of perceptions and to identify areas where there are issues to be addressed. This study describes two surveys which were conducted with 793 students and 793 teachers related particularly to their perceptions. 23 senior staff in the Ministry of Education and Quality Assurance Authority in Kingdom of Bahrain were also interviewed individually in order to gain more information about their perceptions of quality assurance in the Kingdom. It is very evident that the pictures painted by the students, their teachers and those in educational leadership are very different. In particular, the educational leadership standout in offering very different perspectives. It is, therefore, obvious that there is little shared agenda other than an overall wish for educational quality, but what is meant by this is not even clear. There is a clear message that the educational leadership needs to consult and listen more to teachers and students if any shared agenda is to be reached. Perhaps, the teachers have a better insight into reality while the students must take a central role in that the schools are there for their benefit. Several issues stood out from the surveys but two were followed up in this study. The first is that there is considerable disquiet about national assessment (which controls inschool assessment practices). The second is that the students want to move away form the teacher-centred lecture approach to have opportunities to work in groups and discuss.In the light findings of these findings, the examination marks for a sample of 7022students in their final year of school was gained. The data were considered descriptively as well as being analysed using Factor Analysis. It was readily apparent that there are major issues to be addressed and that was perhaps what the students were drawing attention to in the surveys. Firstly, the examination papers are far too easy, with little opportunity for students to show their abilities. Secondly, the factor analyses showed that all the subject examinations merely tested one skill, a scrutiny of papers showingthat was recall. In order to explore the potential role of group working in schools, a sample of 817 students in three age-groups in secondary school undertook a short series of short group-work problem solving exercises in one subject discipline. Student performance as well as their reactions were measured. It was found that there were some advantages in understanding arising from the use of such units but the effects were not universally beneficial for all of the units used. Student reactions tended to be positive but not overwhelmingly so.The main findings revealed that there is a major lack of consistency and sharedunderstanding between those who take the decisions in education (and thedocumentation they generate) and the realities of what goes on in schools (as reflected by teachers and learners). There is a need to focus on the learners, their experiences, their achievements and their needs as they move out into higher education or the workplace. There is a need to widen the range of skills being assessed and to develop resources to enable these skills to grow. Above all, the role of quality assurance in Bahrain has to be one that empowers the teachers rather that inspects them and criticises, often on matters over which teachers have no control.

Cost Effective Quality Assurance Practices in Highway Construction

Newland, James M 01 August 2015 (has links)
The estimated value of the U.S. transportation infrastructure is over $7.0 trillion. The challenge is preserving the quality of the investment. State and federal departments of transportation have methods and procedures for best quality, but vary significantly. With the variations comes opportunity to assess the cost-effectiveness of different strategies and make recommendation on practices that are most successful. A survey was created and sent to all 50 states and the District of Columbia. The survey was aimed to capture information on construction finished product testing methods, optimized/reduced sampling techniques, innovative QA practices that measure multiple performance criteria and QA processes that are rapid and cost effective. There are many testing methods and procedures being used throughout the U.S. This thesis will allow state and federal transportation agencies to look at the findings and possibly implement them into their own agency with hopes of saving time and money for future projects.

The Evaluation and Study of Modern Radiation Dosimetry Methods as Applied to Advanced Radiation Therapy Treatments Using Intensity Modulated Megavoltage Photon Beams

Stambaugh, Cassandra 27 March 2015 (has links)
The purpose of this work is to evaluate quasi-3D arrays for use with intensity modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT) and to determine their clinical relevance. This is achieved using a Delta4 from Scandidos and ArcCheck from Sun Nuclear and the associated software. While certain aspects of these devices and software have been previously evaluated, the main goal of this work is to evaluate the new aspects, such as reconstructing dose on a patient CT set, and extending the capabilities. This includes the capability to reconstruct the dose based on a helical delivery as well as studying the dose to a moving target using measurement-guided motion simulations. It was found that Sun Nuclear's ArcCheck/3DVH system exhibited excellent agreement for dose reconstruction for IMRT/VMAT using a traditional C-arm linear accelerator and stringent 2%/2mm comparison constraints. It also is a powerful tool for measurement-guided dose estimates for moving targets, allowing for many simulations to be performed based on one measurement and the target motion data. For dose reconstruction for a helical delivery, the agreement was not as good for the stringent comparison but was reasonable for the clinically acceptable 3%/3mm comparison. Scandidos' Delta4 shows good agreement with stringent 2%/2mm constraints for its dose reconstruction on the phantom. However, the dose reconstruction on the patient CT set was poor and needs more work. Overall, it was found that quasi-3D arrays are powerful tools for dose reconstruction and treatment plan comparisons. The ability to reconstruct the dose allows for a dose resolution comparable to the treatment plan, which negates the previous issues with inadequate sampling and resolution issues found when just comparing the diodes. The ability to quickly and accurately compare many plans and target motions with minimum setup makes the quasi-3D array an attractive tool for both commissioning and patient specific quality assurance.

Assurance reporting and the communication process: impacts on report users' perceptions and decision-making

Pflugrath, Gary, Accounting, Australian School of Business, UNSW January 2008 (has links)
This thesis investigates the effectiveness of communication between assurors and assurance report users, and the role that assurance reports play in this process. It comprises two behavioural experiments undertaken in the context of: (i) wording changes to the audit report (developed product) using shareholders as participants; and (ii) the role of assurance and type of assurance provider for corporate social responsibility reporting (evolving product), using financial analysts as participants. In both studies effectiveness of communication is examined in terms of report users?? perceptions and investment decision-making. The theoretical framework used in these studies is adapted from a communications model developed by Shannon and Weaver (1949), and supplemented by psychology research focused on source credibility (Birnbaum and Stegner, 1979). Two key elements of the communication process are recognised; the: (i) message transmitted; and (ii) source of the message. The first element is considered in the first experiment; the second element in the second study. Useful feedback is provided to standard-setters. From the first study, report users?? perceptions are not impacted by changes to the wording of the audit report. However, in the second experiment they are affected by differences in the source of the message. In terms of trustworthiness, financial analysts perceive the credibility of the source of corporate social responsibility information to be significantly greater when assured. For a company in an industry with stronger incentives to report positive corporate social responsibility information, they perceive the credibility (trustworthiness, overall credibility) of the source of the information to be significantly greater when assured. They also discern differences between types of assuror whereby the credibility (trustworthiness, expertise, overall credibility) of the source of information is perceived to be greater when assured by a professional accountant than a sustainability expert. A contribution of these experiments is the analysis of report users?? investment decision-making, as well as their perceptions. Differences in the message and source of the message for assurance reporting have no impact on report users?? investment decisions. Differences in characteristics of report users (familiarity with reports, extent to which reports are understandable) appear to impact report users?? perceptions and merits further examination.

Culture and Quality Assurance : an exploration of the relationship between organisational culture and the introduction of quality assurance in small training organisations

Syme, David, n/a January 1999 (has links)
This thesis explores the impact that small training organisations expect as a result of the introduction of quality assurance. It also explores how the culture of small training organisations affects, and is affected by, quality assurance. The current requirement for small training organisations to undertake quality assurance processes represents challenges and opportunities. However, there is little information available on the relationship between organisation culture and quality assurance in small training organisations, and therefore little guidance on implementing quality assurance in such organisations. The relationship between organisational culture and quality assurance in small organisations was examined from an interpretive approach that used both quantitative and qualitative techniques. 78 respondents from 34 separate training organisations responded to a survey comprising a questionnaire developed by the author concerning the expected impact of quality assurance, and an organisational culture instrument. The organisation culture instrument, which was adapted by the author from the Organisational Culture Diagnostic Instrument (Cameron and Ettington 1988), aimed to assess both current organisational culture, and expected organisational culture after the introduction of quality assurance. Further in-depth data were gained in focus groups held with two of training organisations surveyed. Results were analysed using descriptive and inferential statistics, and content analyses. For most small training organisations, the opportunities provided by quality assurance, especially in providing consistency through devolved responsibility for management tasks, were perceived to outweigh the short-term problems, especially resource issues and frustration with inconsistent external requirements. Change for the most part was perceived to be at the level of procedure and formal policy, rather than at the level of underlying values or philosophy. The organisations tended to have flexible cultures ('Clans' and 'Adhocracies' - Cameron and Ellington 1988), and expected to become more predictable ('Hierarchies' and 'Markets' - ibid) after the introduction of quality assurance. However, there were variable paradoxical effects in relation to the impact of quality assurance on organisational culture. The study identifies some key issues for those implementing and/or designing quality assurance systems in small training organisations and suggests that, in comparison with large organisations, more attention needs to be given to technical and resource issues than to changes in orientation or values. The study identifies a number of complexities in the relationships between different aspects of organisational culture, between organisational profile and expected impact, and between expected and actual impact. Further research on these complexities is suggested.

Beliefs and attitudes of middle managers towards quality programs in their organisations.

Davis, Douglas. January 2000 (has links)
University of Technology, Sydney. / This overall objective of this research was to identify factors that were important in forming middle managers' attitudes toward quality and quality programs in their organisations. An underlying assumption of the research, supported by the literature, was that a middle manager's attitude toward his/her quality program could be an important indicator of behaviour toward the program e.g. resistance, willingness to be involved. Reviews of the literature on middle management, quality, attitude measurement and research more specifically related to the research topic was undertaken. The work of Ajzen (1988) was particularly useful in devising an overall theoretical framework for the research . A number of hypotheses related to the overall research question were formulated. Twenty-one organisations agreed to participate in the research. These all had a quality program. Some of the organisations were quite advanced in quality, a number had won Australian Quality Awards, others were much less advanced. Organisations were drawn from manufacturing and services in both private and public sectors. Data was collected in two main ways. Firstly, a questionnaire was designed, piloted and distributed to approximately 1100 middle managers in participating organisations. The response rate was approximately 50%. Secondly, in depth interviews were carried out with middle managers, senior managers and quality managers in a number of the participating organisations. The results generally confirm the importance of the middle management group as key to the success of a quality program. Middle managers across all of the participating organisations generally believed that the TQM approach to management was an effective one. Their views on the effectiveness of IS09000 were less positive. Middle managers generally believed that the quality programs were more likely to benefit their organisations rather than to directly benefit themselves, although quality programs did provide some opportunities for some middle managers. Middle managers generally believed that their quality programs provided both operational and strategic benefit for their organisations. Paradoxically, a widely held belief among middle managers was that quality programs did not reduce short term thinking and over-reacting to short term goals. Positive attitudes to quality in the organisation were associated particularly with the values and beliefs that middle managers held regarding: a) program support from top management, from their direct boss and from their colleagues; b) a range of program outcomes for the organisation and c) a range of program outcomes related to the individual middle manager. For middle managers actively involved in their organisations quality program the clarity of their program role was positively related to program attitudes. Training/education in quality was also significantly related to some beliefs and attitudes towards quality and quality programs. Middle managers generally believed that quality programs involved a significant increase in paper work and bureaucracy. However this was not a significant influence on their attitudes toward quality in their organisations. An important finding was that for a wide range of beliefs and attitudes related to quality no significant differences were found between the types of jobs held by middle managers. An exception was the quality specialist group who generally had significantly more positive attitudes and beliefs about quality and their quality programs than did other job categories. Middle managers seemed relatively at ease with most of the changes that were taking place as part of their programs. In particular they had relatively positive views on devolution of responsibility to lower level employees. Middle managers also seemed relatively at ease with their own performance being more tightly monitored with program implementation. The research supported the more optimistic view of middle Management that has been reported recently (e.g. Fenton-O'Creevy 1998). The notion of the middle management still had currency in all of the organisations participating in the research despite the many structural changes that had taken place.

Flow assurance and multiphase pumping

Nikhar, Hemant G. 15 May 2009 (has links)
A robust understanding and planning of production enhancement and flow assurance is required as petroleum E&P activities are targeting deepwaters and long distances. Different flow assurance issues and their solutions are put together in this work. The use of multiphase pumps as a flow assurance solution is emphasized. Multiphase pumping aids flow assurance in different ways. However, the problem causing most concern is sand erosion. This work involved a detection-based sand monitoring method. Our objectives are to investigate the reliability of an acoustic sand detector and analyze the feasibility of gel injection as a method to mitigate sand erosion. Use of a sand detector coupled with twin-screw pumps is studied under varying flow conditions. The feasibility of gel injection to reduce slip and transport produced solids through twin-screw pump is investigated. A unique full-scale laboratory with multiphase pumps was utilized to carry out the experimental tests. The test results indicate that acoustic sand detection works in a narrow window around the calibration signature. An empirical correlation for predicting the twin-screw pump performance with viscous fluids was developed. It shows good agreement in the practical operational limits – 50% to 100% speed. The results indicate that viscous gel injection should be an effective erosion mitigation approach as it reduces slip, the principle cause of erosive wear. To correlate the performance of viscous fluid injection to hydroabrasive wear, further experimental investigation is needed.

The Assurance Process of GRI Sustainability Reports : ­Influence on Accountability and Transparency

Johansson, Deborah, Lundberg, Therese January 2012 (has links)
Sustainability reporting aims to inform stakeholders of the companies’ activities within environmental, social and economic issues. The reporting is a tool to increase transparency and it shows the company’s effort to take responsibility and account for its actions. Assurance of sustainability reports is an increasing trend that strengthens the credibility of the reports. There is a risk, however, of management taking control over the assurance process. In order to improve the quality of the sustainability report and its usefulness for the stakeholders, reporting and assurance standards have evolved. The purpose of the study is to describe and analyse the assurance statements of sustainability reports of public listed companies in Sweden. The findings allow the evaluation of how the assurance process influences accountability and transparency. The study is a content analysis of eleven assurance statements from 2010. The findings are categorized and analysed by assurance provider: accountants and consultants. The difference between the assurance statements were mainly due to the assurance standard used. The assurance statements provided by the consultants were more descriptive and stakeholder oriented compared to the accountants. We highlight the importance of the assurance process’ usefulness and discuss the limited level of assurance applied in the engagements. We argue that, an open and standardized assurance process increases transparency that enables stakeholders to make own judgements whether the company takes responsibility and accounts for its actions. Transparency also creates incentives for the reporting company to be accountable. To increase transparency and accountability, it is essential to involve stakeholders in the assurance process.
