Initial value generation for matchmaking in middle agents

One of the major challenges that agents used in open environments must face is that they must be able to find each other. This is because in an open environment, agents might appear and disappear unpredictably. To address this issue, middle agents have been proposed. 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. The practical performance of service provider agents has a significant impact on the matchmaking outcomes of middle agents. Thus the track records of agents in accomplishing similar tasks in the past should be taken into account in matchmaking process. Considering that there are no track records available at the launching of an agent system, this paper discusses some ways to provide reasonable initial values for the track  records. With the agents' history and the initial vallies ofthe track records, the performance of matchmaking algorithms can be improved significantly.

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.

Differentiate or die or be 'stuck in the middle' and survive!

“The reality is that traditional (marketing) implementation approaches have failed…” (Dobni et al., 2001, p. 402) Nevertheless recent research still seeks to identify relationships between Porter’s marketing strategies, implementation and performance (Kumar et al. 1997; Teach and Schwartz, 2000). Although each study included the Porter’s strategy types none actually classified business units into ideal differentiators, ideal cost leaders and combination differentiation cost leaders to conduct “implementation-performance process” comparisons.

This study has made a contribution to the study of marketing implementation and marketing performance by separating and comparing strategies such as ideal differentiation, ideal cost leadership, and combination (differentiation/cost leadership) strategies with the “stuck in the middle” marketing strategy type.

A key implementation finding was the importance of paying high salaries to attract the best employees when implementing either a differentiation strategy or a combined (differentiation/ cost leadership) strategy. However for the other six implementation tools, the findings support Kelliher and Perrett (2001, p.421) whose findings “do not indicate a clear relationship between business strategy and the approach to HRM.”

A key performance finding was that differentiation is the best strategy in terms of marketing performance while cost leadership is the worst performing strategy. Both differentiation and the combination strategy (differentiation/cost leadership) outperformed cost leadership.

Soft-sediment deformation structures in the middle permian Wandrawandian siltstone, southern Sydney basin: implications for depositional environment and basin tectonics

The Middle Permian Wandrawandian Siltstone at Warden Head near Ulladulla in the southern Sydney Basin is dominated by fossiliferous siltstone and mudstone, with a large amount of dropstones (lonestones) and some pebbly sandstone beds. Two general types of deposits are recognised from the cliff succession in view of the timing and mechanism of their formation. One is represented by the background (or primary) deposits of offshore to slope environments with abundant dropstones of glacial marine origin. This facies occurs throughout the cliff sections at Warden Head. The second type is distinguished by secondary, soft-sediment deformational deposits and structures of the primary (background) deposits, and comprises three successive layers of sandy mudstone dikes. In the second type of deposit, metre scale, laterally extensive syn-depositional slump deformation structures occur extensively in the middle part of the Wandrawandian Siltstone. The deformation structures vary in morphology and pattern, including large-scale complex-type folds, flexural stratification, concave-up structures, small-magnitude -faults accompanied by folding and brecciation. The slumps and associated syn-depositional structures are herein attributed to penecontemporaneous deformations of soft sediments (mostly mud and silty mud), formed as a result of mass movement of unconsolidated and/or semi-consolidated substrate following earthquake events. The occurrence of the earthquake event deposits (or seismites) at Warden Head supports the current view that the Sydney Basin was located in a back-arc setting near the New England magmatic arc on an active continental margin during the Middle Permian, and the timing of the earthquake events is here interpreted to indicate the onset of the Hunter Bowen Orogeny in the southern Sydney Basin.

A conformity test of corporate financial disclosures in Asian and Middle East countries

This paper investigates the financial disclosure practices of corporate annual reports published in Asian countries including Bangladesh, Indonesian, Malaysia and the Middle East countries including Bahrain, Iran, Jordan, Kuwait, Oman, Pakistan, Qatar, Saudi Arabia and Turkey. The purpose of the study is to measure the financial disclosure diversity in these countries, with a view to developing a classification of their similarities and differences in respect to their compliance with International Accounting Standards (IASs). Annual reports of 132 public companies listed on the relevant countries stock exchanges are the central data source, supplemented with other reliable information about financial disclosure practices in each country. A disclosure checklist adopted from all IASs and summarised in 306 individual items of financial disclosures is used as a means of extending an understanding of financial reporting literature. Additionally, it provides an indication of voluntary progress towards harmonisation of international accounting practices in several Asian and Middle Eastern countries. Results show the degree of conformity with IASs from less to high conformity is: Saudi Arabia, Qatar, Bangladesh, Iran, Bahrain, Jordan, Pakistan, Oman, Turkey, Malaysia, Kuwait and Indonesia.

Digital literacies in the middle years of schooling

This paper uses Glister's interpretation of digital literacy whilst acknowledging that a computer is not the only means for the delivety of digital texts. I will explore how we can support student teachers to develop understandings about the teaching in the middle years in order to work with students in schools to successfully read digital texts, create digital texts, search, fmd and use information in the digital world and to become critical users of digital texts. Students in the middle years of schooling are facing increasingly sophisticated literacy demands of new technologies that go well beyond that of the traditional printed page as they interact with information communicated through a range of digital media both inside and outside of school. At best new technologies can open doors to students for researching and accessing a world far beyond their own environment, empowering them to direct and control their own learning and produce quality work.

Interpersonal trust and control behaviour of Chinese managers

Interpersonal trust is believed to influence the management and control of organisations in China. China's importance as a host country for foreign direct investments (FDIs) through multinational company subsidiaries (MNCs) and international joint ventures (IJVs) is growing rapidly. MNCs and INs located in China often employ local Chinese managers to control their subsidiaries or ventures. This makes it essential for designers of management control systems to have an understanding of the interpersonal trust-sensitive control behaviour of Chinese managers. One of the important aspects of control behaviour is how managers control their subordinates.

This paper examines the relationship between Chinese managers' trust in subordinates and their (Chinese managers') control behaviour towards the subordinates. On the basis of a questionnaire survey of a cohort of managers from Beijing, the study explores the effects of trust on the use of social controls, formal controls, and monitoring.

The findings of this study indicate that a manager's high (low) trust in a subordinate is associated with a low (high) level of monitoring, a high (high) level of social control and a high (low) level of perceived performance. The hypothesis that a superior's high (low) level of trust is associated with a low (high) level of reliance on formal controls was not supported. These findings, while indicative of control behaviour of Chinese managers in particular, also add to the growing academic literature on trust and control in general. In a practical sense, an
understanding of the trust-sensitive control behaviour of Chinese managers is particularly useful in designing and implementing effective control systems for international organisations operating in China.

Future considerations for the training and development of Australian quality managers

Adequate, appropriate training of quality managers is essential to the development and implementation of effective quality management systems. This study reports on a survey of 235 Australian quality managers to determine their perceptions of their training and development needs, the extent to which these were being met, and their views on the future of their discipline. The study found that there was a general lack of systematization, most programs were short-term and delivered by a fragmented set of providers. Many managers had received no training in the past 5 years. While the respondents were generally satisfied with the training they had received, there was evidence that their insight into their own needs was imperfect. The respondents were divided between those who thought quality management would remain a discrete field and those who saw it being absorbed by other management systems. The challenges of developing an appropriate training and development regime in this environment are discussed.

Mentoring volunteer festival managers : evaluation of a pilot scheme in regional Australia

Festival managers in regional locations often have limited access to didactic experiences in their field. As such, developing strategies that enhance the skills of festival management in regional locations can be challenging. This paper, set within the context of the Australian regional arts festival sector, evaluates a pilot mentoring scheme developed by Regional Arts Victoria and Arts Victoria to assist volunteer festival managers to enhance the management, and focus the artistic direction, of their festivals. The results of the evaluation, based on six case studies, indicate that mentoring is highly suited to this scenario. Recommendations are made with regard to the future application of mentoring within this context, particularly in relation to communication and formalisation.
