Has quality management run its course? Views from the field

The aim of this paper is to assess and reflect on, through the perspectives of Australian Quality practitioners, the current status of quality management; whether there had been any significant and recent shift in their roles and responsibilities; and if there had been any improvement in the extent to which their development and training needs were being fulfilled. This paper sets out to identify the roles, responsibilities, and training and development needs of Australian quality managers and what impact these may be having on the current 'quality agenda' of organisations in Australia. In light of these findings this paper focuses on the HR people aspects of QM implementation (e.g. development of a quality culture; learning, training and development; leadership and management commitment and support) and the significance of these aspects for sustainable QM implementation. Recent literature On QM implementation and the findings of three previously conducted surveys (Waddell 1998; Waddell and Mallen 2001; and Stewart and Waddell 2003) have been integrated with the findings of this research.

Milkfat characteristics and functionality: opportunities for improvement

Manipulation of the composition of milkfat has the potential to improve the nutritional properties and physical functionality of milkfat and its acceptability in the market. The modifications that have been targeted from a nutritional perspective have included:
(a) reducing the ratio of saturated to unsaturated fatty acids;
(b) increasing the level of omega-3 polyunsaturated fatty acids; and
(c) increasing the content of conjugated linoleic acid.
From a physical functionality viewpoint, the outcome targeted has been an improvement in the spreadability of butter by altering milkfat composition to reduce the hardness of milkfat. Both on-farm strategies and the application of appropriate post-farm processing technologies may be used to alter the milkfat composition to enhance its nutritional image and its physical functionality for a range of product applications. However, changes in milkfat composition that are desirable for a specific nutritional purpose or for one type of milk-based product may not meet all the desirable requirements of another milkfat or dairy product. Furthermore, modification of the milkfat composition can also have an influence on the processing characteristics of milk and the quality of finished dairy products. It is essential to substantiate the benefits of specific target nutritional or physical functionality outcomes before the introduction of breeding goals, altered milk production systems or post-farm processing operations to manipulate milkfat composition. This paper reviews the variation in milkfat characteristics and the strategies that have been used to modify milkfat composition to achieve milkfat with altered nutritional and physical functional properties.

Academic pedagogies, quality logics and performative universities : evaluating teaching and what students want

Universities have focused on teaching and learning at a time when quality has become the marker of distinction in international higher education markets. Education markets have meant pedagogical relations have become contractualised with a focus on student satisfaction, exemplified in consumer-oriented generic evaluations of teaching. This article argues, by analysing one example, that generic evaluations are more about accountability and marketing than about improvement of teaching and learning. Furthermore, what students want is not the only criterion for judging teaching. Rather, professionals require, as do academics, a capacity for critical judgement about what constitutes valued knowledge in the pedagogical relationship between teacher and student.

Using large group methods to develop effective quality cultures

It has become evident that higher education institutions in the Sultanate of Oman are currently experiencing change, in particular when it involves implementing quality management systems. The underlying principles of quality management are participatory decision making. Our methods for conducting improvements in quality management, strategic planning and other topics model this principle. Large group methods or interventions involve gathering an entire organization to talk about, influence or invent needed changes (Bunker & Alban, 2002). Change is a result of purposeful social construction by organizational members. It involves a goal (approach/plan), implementation (deployment/act/so), evaluation (results/check) and modification (improvement). This paper explores the different large group methods being used in the field today and it proposes that large group methods allow a forum to overcome some of the hurdles and challenges that are being faced in Oman such as; How do you encourage sharing information in a fiercely competitive environment? And how do you establish an informal network of peers? We were witness to some of these challenges being over come when we used large group methods during various strategic planning workshops with members of staff from the different colleges in Oman. Results from the evaluations of the workshops highlighted that participants enjoyed the opportunity to network and share ideas with their peers as well as being involved in group discussions and brainstorming ideas. The paper will also propose that large group methods can be used effectively in Omani culture strengthening goals towards Omanisation.

Water quality, bacterial flora and production in shrimp farms in Sri Lanka

This study investigated the possibilities of improvement in the brackish water shrimp culture industry in Sri Lanka. Feeding rates could be further reduced without negative effect on shrimp growth while improving effluent water quality. Improvements of feed quality and pond management practices were also suggested.

Towards a more holistic approach to quality improvements in aluminium die casting

This work evaluates the feasibility of using a holistic approach, based on dynamical system theory,
to reduce porosity defects in high pressure aluminum die casting. Quality improvements, from a
dynamical system perspective mean the ability to move the die casting process out of its natural
equilibrium to a more beneficial state and the ability to maintain this new process state. This more beneficial state may be achieved in several ways. One way is to increase the amount of forcing to overcome natural process resistance. This forcing approach is represented by typical continuous intervention policy, with modifications in die/part design and/or process parameters. An alternative approach is to reduce the amount of natural process resistance, in particular the amount of process disturbance, allowing the process to move out of its natural equilibrium with much less forcing. This alternative uses the self-regulating ability of dynamical systems thus decreasing the amount of human intervention required. In this respect, the influence of vacuum on time on chattering at the first stage of the casting shot was identified as a good process candidate for testing using dynamical system theory. A significant reduction in porosity defects was achieved, which also set the process on a path of slow but consistent self-improvement.

Volunteering and quality of life of the older age population

The contribution of volunteers to society and economy is substantial. The participation in voluntary work is on the increase, particularly by the over 55 age group. Given the aging of the Australian population, this growth has an important social consequence. The aim of this conceptual study is to review the influences of older age Australian volunteering practice, its growth pattern and the types of voluntary work undertaken. The study uses the expectancy theory of motivation to argue that volunteers participate for the perceived benefits they get from their interaction with others, by experiencing self-esteem from being useful, being connected, gaining self-satisfaction, and by focusing on giving. It reviews the issue of quality of life (QOL) in relation to voluntary social engagement and suggests that there is an association between the older age group voluntarism and improvement in their QOL. The role of policy makers in further motivating larger participation by the older age groups and the social benefits emerging from this strategy is briefly reviewed.

Improving wool/polyester yarn quality by transposal spinning with movable balloon control ring

To improve yarn quality in ring spinning frame, this paper examines transposal spinning with the movable balloon control ring. The left-transposal spinning and the right-transposal spinning were experimented to spin two yarns; after installing the movable balloon control ring, the two methods were respectively used to spin two other yarns again. All the experiments were on the same ring frame and the raw material was wool/polyester blend roving with a ration of 30/70. The main quality indexes of the four yarns were tested and analyzed, including hairiness, tensile property, evenness and usual faults. The results show that the yarn spun by the left-transposal spinning has a better quality than the right-transposal spinning, and after adding the movable balloon control ring, the improvement of yarn hairiness strength and evenness, as well usual faults, is very obvious. So, in the advantage of transposal spinning, the method of installing the movable balloon control ring can improve some deteriorative problems and make yarn quality better. In addition, the method gives new insight into energy efficiency. The research in this field in on the way and the result is in accord with the Low-carbon Economy.

The effect of resistance training on functional capacity and quality of life in individuals with high and low number of metabolic risk factors

OBJECTIVE—There are limited data on the effects of resistance training on the capacity to perform activities of daily living (ADLs) and quality of life (QoL) for individuals with a high number of metabolic risk factors (HiMF). In this study, we examined the effect of resistance training on the capacity to perform ADLs and QoL in individuals with HiMF and compared any benefits with individuals with a low number of metabolic risk factors (LoMF).

RESEARCH DESIGN AND METHODS—Fifty-five untrained individuals, aged 50.8 ± 6.5 years, were randomized to four groups: HiMF training (HiMFT), HiMF control, LoMF training (LoMFT), and LoMF control. At baseline and after 10 weeks of resistance training, participants underwent anthropometric measurements and assessments of aerobic power (Vo2peak), muscle strength, capacity to perform ADLs, and a self-perceived QoL questionnaire. A repeated-measures ANOVA was used to examine the effect of training over time among groups.

RESULTS—Training increased lean body mass in both HiMFT (P = 0.03) and LoMFT (P = 0.03) groups. Total fat content and Vo2peak improved in the LoMFT group only. Muscle strength improved in both training groups (P < 0.01). Time to complete ADLs was reduced by 8.8% in the LoMFT group (P < 0.01) and 9.7% in the HiMF group (P < 0.01). Only the HiMFT group reported improvement in QoL.

CONCLUSIONS— Resistance training improved muscle strength and the capacity to perform ADLs in individuals with HiMF and LoMF. Resistance training improved QoL for the HiMF group, and this result was independent of changes in body fat content or aerobic power. Longer training regimens may be needed to improve QoL in individuals with LoMF.

Health-related quality of life and functioning in bipolar disorder : the impact of pharmacotherapy

Bipolar disorder has a major deleterious impact on many aspects of a patient's functioning and health-related quality of life. Although the formal measurement of these deficits has been neglected until recently, many well-designed trials now include an assessment of functioning and health-related quality of life using one or more rating scales. This review describes recent developments in the measurement of functioning and health-related quality of life in bipolar disorder, and discusses the evidence that medications that improve symptoms in bipolar disorder also offer clinically relevant benefits in functioning and health-related quality of life. Direct comparisons of the benefits of medications including atypical antipsychotics are problematic due to differences in trial populations, study durations and rating scales. Data from quetiapine trials indicate that this medication offers prompt and sustained improvement of functioning in patients with mania and enhancement of health-related quality of life in patients with bipolar depression, to accompany the significant improvements in mood episodes.

A preliminary investigation of the utility of the "Behavior support plan quality evaluation guide II" for use in Australia

Background The quality of behaviour support plans (BSPs) can be an important influence on the quality of the support provided to people with disability who show challenging behaviours. The Behavior Support Plan Quality Evaluation Guide II (BSP-QE II) is one tool that may be useful in assessing the quality of behaviour support plans. It has previously been used to assess BSPs to support children in schools in the USA. In this preliminary study, we examined the utility of the BSP-QE II for assessing behaviour support plans designed for adults with an intellectual disability in community support services in Australia.

Method  Experienced practitioners were surveyed concerning the relevance of BSP-QE II components to the evaluation of BSPs in Australia, and an audit was conducted of randomly selected BSPs submitted as a statutory requirement to the Office of the Senior Practitioner.

Results  The BSP-QE II showed evidence of acceptable construct validity and interrater reliability. There was evidence of a need for substantial improvement in the quality of BSPs, consistent with previous findings conducted using other audit tools.

Conclusions The findings support the utility of the BSP-QE II, to inform and evaluate service planning in supporting adults with intellectual disability who show challenging behaviour.

Adaptive depletion for improvement of MPEG video compression

Traditional data compression algorithms for 2D images work using the information theoretic paradigm, attempting to reduce redundant information by as much as possible. However, through the use of a depletion algorithm that takes advantage of characteristics of the human visual system, images can be displayed using only half or a quarter of the original information with no appreciable loss of quality.

The characteristics of the human visual system that allows the viewer to perceive a higher rate of information than is actually displayed is known as the beta or picket fence effect. It is called the picket fence effect because its effect is noticeable when a person is travelling along a picket fence. Despite the person not having an unimpeded view of the objects behind the fence at any instant, as the person is moving, the objects behind the picket fence are clearly visible. In fact, in most cases the fence is hardly noticeable at all.

The techniques we have developed uses this effect to achieve higher levels of compression than would otherwise be possible. As a fundamental characteristic of the beta effect is the requirement that there is movement of the fence in relation to the object, the beta effect can only be used in image sequences where movement between the depletion pattern and objects within the image can be achieved.

As MPEG is the recognised standard by which image sequences are coded, compatibility with MPEG is essential. We have modified our technique such that it performs in conjunction with MPEG, providing further compression over MPEG.

Six sigma approach to improve quality in E-services : an empirical study in Jordan

In the last two decades, Six Sigma approach has found its success in manufacturing sectors. The relevance of Six Sigma methodologies in service sector has been realised more recently. This paper investigates the application of Six Sigma approach to improve quality in electronic services (e-services) as more and more countries are adopting e-services as a means of providing services to their community and people through the Web. In particular, this paper presents a case study about the use of Six Sigma model to measure the customer satisfaction and quality levels achieved in e-services that were recently launched by public sector organisations in a developing country, such as Jordan. An empirical study consisting of 280 participating customers of Jordan‘s e-services is conducted and the problems are identified through the DMAIC phases of Six Sigma. The service quality levels are measured and analysed using six main criteria, namely, Website Design, Reliability, Responsiveness, Personalization, Information Quality, and System Quality. The overall result of the study indicating a 74% customer satisfaction with a Six Sigma level of 2.12 has enabled the Greater Amman Municipality to identify the usability issues associated with their e-services offered by public sector organisations and to take the leads from the results of the study to improve customer satisfaction. The aim of the paper is not only to implement Six Sigma as a measurement-based strategy for improving e-customer service quality in a newly launched e-service programme, but also to help widen its scope in investigating other service dimensions and perform comparative studies in other developing countries as future research.

A model to select processes for IT service management improvement

IT organisations are continually seeking improvements in managing IT service management processes. The selection of relevant processes to improve is one of the most crucial initial decisions to make in service improvement projects. In this paper, we focus on developing a process selection decision model using service perception factors from the Service Quality (SERV-QUAL) model and business drivers from the Balanced Scorecard perspectives along with the main objective of service improvement as improvement driver. We use a Design Science Research method to develop the model and then a prototype from our proposed model. We establish an evaluation protocol to determine the effectiveness of the prototype which will be demonstrated in a case organisation. The main contribution of the paper is to provide evidence-based decision support for IT service providers to select the most relevant service processes to improve.

Characterization of the improvement in depressive symptoms following Bariatric surgery

Background : The Beck Depression Inventory (BDI) has been frequently employed as a measure of depression in studies of obesity, with the majority of studies reporting an improvement in scores following weight loss. Given the potential similarity in obesity-related and depressive symptoms, it is uncertain whether all components of depression would improve equally with weight loss.

Method : The study included obese patients who had undergone laparoscopic adjustable gastric banding (LAGB) surgery and had completed BDIs at baseline and 1 year after surgery. Two groups of patients were included, a general background group (N = 191, mean age = 41 ± 9, mean BMI = 43 ± 8) and a group identified as experiencing elevated depressive symptoms based on BDI scores ≥23 (EDS group; (N = 67, mean age = 40 ± 9, mean BMI = 45 ± 7).

Results : Overall, BDI scores fell for both groups, background group at baseline 17 ± 9–8 ± 7 at 1 year and for the EDS group at baseline 30 ± 5–14 ± 10 at 1 year. Patient scores on the negative self-attitude subscale were significantly greater than the two other subscales and showed the greatest improvement 1 year following LAGB. Preexisting antidepressant therapy had little or no association on the BDI scores or on its change following weight loss.

Conclusion : High rates of depression are continually reported in obesity, as is a remarkable decrease in depressive symptoms following weight loss. Negative attitudes towards one’s self appears to be driving elevated BDI scores rather than the overlap in physical symptoms between obesity and depression.
