The e-learning cycle and continuous improvement for e-entrepreneurs

The purpose of this paper is to explore the integration of learning, continuous improvement and innovation theories as a basis for enhancing the education of e-entrepreneurs. Conceptual development of emerging interdisciplinary literature is combined with example analysis to develop the Circle of E-learning uniquely augmented by hermeneutics, action research and the creative destruction cycle of innovation using applied examples of e-entrepreneurship. Four R's are discussed in the Circle of E-learning; Review, Revise, Reconstruct, and Reveal. Observations for each of the 4R's are made regarding continuous improvement of the education of e-entrepreneurs. Findings are that the procedural pivot points indicated by the 4R's can be helpful for administrators and educators to improve operations and outcomes in management and professional development situations.

End-to-end QoS framework for heterogeneous wired-cum-wireless networks

With information access becoming more and more ubiquitous, there is a need for providingQoSsupport for communication that spans wired and wireless networks. For the wired side, RSVP/SBM has been widely accepted as a flow reservation scheme in IEEE 802 style LANs. Thus, it would be desirable to investigate the integration of RSVP and a flow reservation scheme in wireless LANs, as an end-to-end solution for QoS guarantee in wired-cum-wireless networks. For this purpose, we propose WRESV, a lightweight RSVPlike flow reservation and admission control scheme for IEEE 802.11 wireless LANs. Using WRESV, wired/wireless integration can be easily implemented by cross-layer interaction at the Access Point. Main components of the integration are RSVP-WRESV parameter mapping and the initiation of new reservation messages, depending on where senders/receivers are located. In addition, to support smooth roaming of mobile users among different basic service sets (BSS), we devise an efficient handoff scheme that considers both the flow rate demand and network resource availability for continuous QoS support. Furthermore, various optimizations for supporting multicast session and QoS re-negotiation are proposed for better performance improvement. Extensive simulation results showthat the proposed scheme is promising in enriching the QoS support of multimedia applications in heterogeneous wired-cum-wireless networks.

Ensuring quality during monitoring of the learning environment of government primary schools achieved through EUI-PDP for teachers and head teachers

A positive change in the learning environment in schools is visible through ongoing professional development of teachers and administrators. Monitoring the professional development program and providing support to teachers and administrators to transfer their learnings into the school environment ensures some measures of quality. Quality issues led to the launching of the Professional Development Program (PDP) for Primary School Teachers (PSTs) of Sindh by the United Educational Initiative (UEI), a consortium of five Governmental and Non-Governmental Organizations, working under the supervision of Education Sector Reform Assistance (ESRA). Implementation of the UEI-PDP in four districts of Sindh, is ensured by a team of professionals in each district. Recognising that capacity building of district education employees would improve the educational system in the country, 130 Master Trainers were selected, on merit, from the District Education Office for the training of 17,000 teachers and 3000 Head teachers/administrators over a period of two years. This paper developed the design of a Monitoring Process for a Professional Development Program for Primary School Teachers and Administrators. Data was collected through Pre/Post observations, Interviews, Questionnaires and Reports. Such tools make it possible for the monitoring teams to observe, to inquire further, and, along with the Managers, Master Trainers and School Support Team, seek to explain the progress of the program and take corrective action where indicated. Both formative evaluations as well as summative  evaluation techniques are utilized for evaluating the program. The monitoring process that assisted in formative evaluations is described. In order to assist in summative evaluation, data collected through the monitoring process was further developed to categorize the schools where teachers and head teachers are trained. It is hoped that the categorization of the schools may lead to further improvements in those schools which fall in the group for need improvement. It may also initiate further research as to reasons behind why some schools are in the good category and why others fall in the average category.

An improvement to matchmaking algorithms for middle agents

A question frequently asked in multi-agent systems (MASs) concerns the efficient search for suitable agents to solve a specific problem. To answer this question, different types of middle agents are usually employed. The performance of middle agents relies heavily on the matchmaking algorithms used. Matchmaking is the process of finding an appropriate provider for a requester through a middle agent. There has been substantial work on matchmaking in different kinds of middle agents. To our knowledge, almost all currently used matchmaking algorithms missed one point when doing matchmaking -- the matchmaking is only based on the advertised capabilities of provider agents. The actual performance of provider agents in accomplishing delegated tasks is not considered at all. This results in the inaccuracy of the matchmaking outcomes as well as the random selection of provider agents with the same advertised capabilities. The quality of service of different service provider agents varies from one agent to another even though they claimed they have the same capabilities. To this end, it is argued that the practical performance of service provider agents has a significant impact on the matchmaking outcomes of middle agents. An improvement to matchmaking algorithms is proposed, which makes the algorithms have the ability to consider the track records of agents in accomplishing delegated tasks. How to represent, accumulate, and use track records as well as how to give initial values for track records in the algorithm are discussed. A prototype is also built to verify the algorithm. Based on the improved algorithm, the matchmaking outcomes are more accurate and reasonable.

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.

Television time and continuous metabolic risk in physically active adults

Purpose: Among Australian adults who met the public health guideline for the minimum health-enhancing levels of physical activity, we examined the dose-response associations of television-viewing time with continuous metabolic risk variables.

Methods: Data were analyzed on 2031 men and 2033 women aged >= 25 yr from the 1999-2000 Australian Diabetes, Obesity and Lifestyle study without clinically diagnosed diabetes or heart disease, who reported at least 2.5 h·wk-1 of moderate- to vigorous-intensity physical activity. Waist circumference, resting blood pressure, and fasting and 2-h plasma glucose, triglycerides, and high-density-lipoprotein cholesterol (HDL-C) were measured. The cross-sectional associations of these metabolic variables with quartiles and hours per day of self-reported television-viewing time were examined separately for men and for women. Analyses were adjusted for age, education, income, smoking, diet quality, alcohol intake, parental history of diabetes, and total physical activity time, as well as menopausal status and current use of postmenopausal hormones for women.

Results: Significant, detrimental dose-response associations of television-viewing time were observed with waist circumference, systolic blood pressure, and 2-h plasma glucose in men and women, and with fasting plasma glucose, triglycerides, and HDL-C in women. The associations were stronger in women than in men, with significant gender interactions observed for triglycerides and HDL-C. Though waist circumference attenuated the associations, they remained statistically significant for 2-h plasma glucose in men and women, and for triglycerides and HDL-C in women.

Conclusions: In a population of healthy Australian adults who met the public health guideline for physical activity, television-viewing time was positively associated with a number of metabolic risk variables. These findings support the case for a concurrent sedentary behavior and health guideline for adults, which is in addition to the public health guideline on physical activity.

Student learning orientations : are there differences between age and gender?

The increasing diversity and mobility of students have challenged universities, world over, to review educational courses and delivery to provide a more satisfying learning environment to students. The continuous improvement of the 'quality' of teaching and learning is one of the key goals of universities endeavouring to fulfil their obligations as learning institutions. Using a revised SPQ2F instrument (Biggs, 2003, Biggs and Leung, 2001), this exploratory study undertakes a comparative analysis of the age and gender differences in the learning orientations of two groups of tertiary students in an Australian University. The results indicate that there are no significant differences in the learning orientations of students but on average they seem to demonstrate deep learning than surface learning although they may differ in terms of the learning contexts.

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.

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.
