  • Description: This study investigated five Chinese higher education institutions in relation to management of academic staff. The study compared these practices with those used in three Australian universities. The results demonstrated that the Chinese universities provide more freedom to academic staff in terms of how staff spend their time at the university. However, there are more strict measures to control teaching staff’s punctuality in attending their classes and to have detailed planning and teaching documentation. There are also additional teaching evaluations at both school and university levels, together with student evaluation. Chinese higher education staff management places greater emphasis on extrinsic financial rewards to improve staff performance than do their Australian counterparts. The income of Chinese academic staff is performance based and closely connected to their teaching, supervision, research and management workload. This approach initially came from the West and is now adopted by Chinese higher education management, reflecting Chinese socialist principles regarding income distribution. This measure of distribution is a very important motivational factor designed to enhance staff performance. This study provides an understanding as to the reasons why differences exist in management practices in China and Australia and offers some explanations from historical, political and social culture perspectives. This research identifies both positive and negative aspects of the two systems and suggests that learning good management practices from each other may bring positive changes to the productivity of higher education in both countries.

  • Description: Since the early 1970s Australia has been described as a multicultural society. Australian Government policy, portfolios and promotion of cohesive and co-operative communities aim to encourage understanding of cultural backgrounds of all who comprise it. Considering the importance of language to everyday life, very tittle research has been undertaken on the role of language on the Victorian goldfields. This chapter deals with the impact of language on non-English speakers, specifically Italian speakers from the Jim Crow goldfield. It can be assumed that other non-English speakers on other goldfields throughout Victoria experienced similar difficulties to those at Jim Crow.

  • Description: A deterministic model of the vertical jump: implications for training. J. Strength Cond. Res. 21(3):967-972. 2007. - Increasing vertical jump height is a critical component for performance enhancement in many sports. It takes on a number of different forms and conditions, including double and single legged jumps and stationary and run-up jumps. In an attempt to understand the factors that influence vertical jump performance, an extensive analysis was undertaken using the deterministic model. Once identified, practical training strategies enabling improvement in these factors were elucidated. Our analysis showed that a successful vertical jump performance was the result of a complex interplay of run-up speed, reactive strength, concentric action power of the take-off leg(s), hip flexors, shoulders, body position, body mass, and take-off time. Of special interest, our analysis showed that the concentric action power of the legs was the critical factor affecting stationary double leg vertical jumps, whereas reactive strength was the critical component for a single leg jump from a run-up. © 2007 National Strength & Conditioning Association.

  • Description: In this paper, a filled function method for solving constrained global optimization problems is proposed. A filled function is proposed for escaping the current local minimizer of a constrained global optimization problem by combining the idea of filled function in unconstrained global optimization and the idea of penalty function in constrained optimization. Then a filled function method for obtaining a global minimizer or an approximate global minimizer of the constrained global optimization problem is presented. Some numerical results demonstrate the efficiency of this global optimization method for solving constrained global optimization problems. © 2007 Springer Science+Business Media, Inc.

  • Description: In pattern recognition problems features plays an important role for classification results. It is very important which features are used and how many features are used for the classification process. Most of the real life classification problem uses different category of features. It is desirable to find the optimal combination of features that improves the performance of the classifier. There exists different selection framework that selects the features. Mostly do not incorporate the impact of one category of features on another. Even if they incorporate, they produce conflict between the categories. In this paper we proposed a restricted crossover selection framework which incorporate the impact of different categories on each other, as well as it restricts the search within the category which searching in the global region of the search space. The results obtained by the proposed framework are promising.

  • Description: Disruptions to commercial airline schedules are frequent and can inflict significant costs. In this paper we continue a line of research initiated by Vranas, Bertsimas and Odoni [15, 16], that aims to develop techniques facilitating rapid return to normal operations whenever disruptions occur. Ground Holding is a technique that has been successfully employed to combat disruptions at North American airports. However, this alone is insufficient to cope with the problem. We develop an adaptive optimization model that allows the implementation of other tactics, such as flight cancellations, airborne holding and diversions. While the approach is generic, our model incorporates features of Sydney airport in Australia, such as a night curfew from 11:00pm to 6:00am. For an actual day when there was a significant capacity drop, we demonstrate that our model clearly outperforms the actions that were initiated by the air traffic controllers at Sydney.

  • Description: Resistive plate chambers (RPCs) have been chosen as a part of the muon trigger detectors in the CMS experiment. They are used both in the endcaps and in the barrel regions, and they have to work in an extreme radiation background. Test of glass-RPC detectors have been performed in order to investigate their performance in such situations. In the present work, the simulation response of glass-RPCs exposed to positrons/electrons is evaluated. As expected a lower sensitivity of glass-RPC with respect to the bakelite-RPC has been observed since the glass density is higher and therefore a lower fraction of electrons can reach the gas gap. The obtained results were applied to CMS/RPC endcap and barrel regions, and their respective sensitivities to those particles are reported together with hit rates. © 2007 Elsevier Ltd.

A public want and a public duty [manuscript] : The role of the Mechanics' Institute in the cultural, social and educational development of Ballarat from 1851 to 1880

  • Description: Mechanics’ Institutes were an integral element of the nineteenth-century British adult education movement, which was itself part of an on-going radicalisation of the working class. Such was the popularity of Mechanics’ Institutes, and so reflective of contemporary British cultural philosophy, that they were copied throughout the British Empire. The Ballaarat Mechanics’ Institute, established in 1859, instilled a powerful, male-gendered British middle-class influence over the cultural, social and educational development of the Ballarat city. The focus of this study is to identify and analyse the significance of the contribution made by the Ballaarat Mechanics’ Institute to the evolving cultural development of the wider Ballarat community, with a particular emphasis on the gender and class dimensions of this influence. This is done within the context of debates about ‘radical fragments’ and ‘egalitarianism’. Utilizing a methodology based on an extensive review of archival records, contemporary newspapers held at the Ballaarat Mechanics’ Institute, and previously published research, this study was able to show that, during the period from its inception in 1859 to 1880, the Institute became a focal point for numerous cultural, social and educational activities. As one of the few institutions open to all classes, it was in a position to provide a significant influence over the developing culture of the Ballarat community. The study has also identified the use made of the Institute’s School of Design by women and the contribution of these educational classes to preparing women for employment outside their traditional roles of wives and mothers. The thesis argues that despite some early radical elements, the Ballaarat Mechanics’ Institute initially espoused liberal egalitarian values. By 1880, however, the Institute was more readily identifiable as reflecting British, male, middle-class values.

  • Description: Year-long team projects with external clients provide a well recognized opportunity for students to gain industry experience, whilst being supported and guided by staff to minimize risks. Each group should be supervised to ensure that they have enough direction and confidence to approach a new problem of significant size, without being daunted. A structure is needed that is flexible and adaptable to suit various institutional cultures but, at the same time, provides the safety net to ensure that success is likely. This paper presents a reflective analysis of teaching at three different institutions and presents the resulting distilled wisdom of experience that has produced a structured framework for capstone project units.

  • Description: The Mathematics and Technology Attitudes Scale (MTAS) is a simple scale for middle secondary years students that monitors five affective variables relevant to learning mathematics with technology. The subscales measure mathematics confidence, confidence with technology, attitude to learning mathematics with technology and two aspects of engagement in learning mathematics. The paper presents a model of how technology use can enhance mathematics achievement, a review of other instruments and a psychometric analysis of the MTAS. It also reports the responses of 350 students from 6 schools to demonstrate the power of the MTAS to provide useful insights for teachers and researchers. 'Attitude to learning mathematics with technology' had a wider range of scores than other variables studied. For boys, this attitude is correlated only with confidence in using technology, but for girls the only relationship found was a negative correlation with mathematics confidence. These differences need to be taken into account when planning instruction. © 2005 Elsevier Ltd. All rights reserved.

  • Description: In this paper, we propose and describe sProxy - smart proxy, a software tool in Web Services transaction. sProxy acts as a gateway between transaction management systems and Web services which implements a key abstraction of proxy management systems. This enables to perform transactions in the loosely coupled environment i.e. loose coupling among services. Proxies are useful to invoke Web services to allow an easy programming model that facilitates the serialization and transmission of service invocations. Our proposed model supports relaxation of traditional ACID properties with existing commit and recovery protocols. The model works on non-ACID type of transactions which encapsulates Web services. It also uses multithreading proxies to check and update transaction simultaneously. The proposed model solves the current problems with distributed computational activities which involves both transactions and Web Services. The proposed model is more abstract and generic as demonstrated in the paper.

  • Description: Purpose - This paper aims to replace the complicated iterative procedure used to prevent interference in limacon-to-limacon machines by a simplified mathematical equation which can be solved by a straightforward substitution of the required clearance value. Design/methodology/approach - The input data to the iterative procedure and the obtained results have been employed in regression models to construct the sought after equation. Searching for a proper form of this equation involved numerical experiments to study the effects of the various model parameters on the system response. Findings - The numerical experiments conducted proved to be an effective model construction technique, and the regression model proposed has been found extremely accurate in the specified parameter space. Research limitations/implications - The proposed equation is applicable within the parameter range chosen for the study. This range is the one often used for industrial applications. Should the parameters selected for a specific design fall outside the specified range, the proposed model structure may have to be varied to maintain a desirable level of accuracy. Practical implications - The interference study is a part of the iterative procedure employed to design the dimensions of the limaçon-to-limaçon machine. This iterative procedure searches for the proper design amongst hundreds of various possible solutions. The results of this paper will ensure a much faster convergence for the design procedure, since the interference study will be eliminated from the iterative section of the analysis. Originality/value - The paper offers a valid and accurate model that can be efficiently used for the intended purpose. © Emerald Group Publishing Limited.
