The professional fields of information systems and information technology are drivers and enablers of the global economy. Moreover, their theoretical scope and practices are global in focus. University graduates need to develop a range of leadership, conceptual and technical capacities to work effectively in, and contribute to, the shaping of companies, business models and systems which operate in globalised settings. This paper reports a study of the operation of industry-based learning (IBL) at three Australian universities, which employ different models and approaches, as part of a series of investigations of the needs, circumstances and perspectives of various stakeholders (program coordinator, faculty teaching staff, the students, industry mentors, and the professional body which has supported the most recent stage of this study). The focus of this paper is a discussion of salient pragmatic considerations as we attempt to conceptualise what constitutes best practice in offering industry-based learning for higher education students in the disciplines of information systems and information technology.

A novel geographic routing protocol for multi-hop wireless sensor networks is presented. It exploits the broadcast nature of the wireless channel to enable on-demand cooperative relaying and leapfrogging for circumventing weak radio links. In order to achieve energy efficiency, a metric is introduced for next-hop selection that takes into account information on the residual battery energy, the geographical position of the sensor nodes, and the channel quality of the involved radio links when available. Performance results show that the completely decentralized protocol offers significant benefits by reducing the number of (re)transmissions required to reach the destination. This translates into network-wide energy savings that extend the network lifetime.

In the past, New South Wales cooperative housing societies made an important contribution to the financing of housing construction. In this paper the expansion and later contraction of the societies is explained. It is shown that, in recent times, not only have they suffered from a drying up of loan funding, but also a great number have operated at far below their possible level of efficiency.

This paper presents an efficient technique to design dynamic feedback control scheme for single-link flexible manipulators.  A linear model can be derived for the robotic system using the assumed-mode method.  Conventional techniques such as pole-placement or LQR require physical measurements of all systme states,  posing a stringent requirement for its implementation.  To overcome this problem, a low-order state functional observer is proposed here for reconstruction of the state feedback control action.  The observer design involves solving an optimisation problem with the objective to generate a feedback gain that is as close as possible to that of the required feedback controller.  A condition for robust stability of the closed-loop system under the observer-based control scheme is given.  The attractive features of the propsed technique are the resulted functional state observer is of a very low order and it requires only sensor measurements of only the output- the tip position of the arm.

University graduates need to develop a range of leadership, conceptual and technical capacities to work effectively in, and contribute to, the shaping of companies, business models and systems which operate in globalised settings. This paper reports a study of the operation of industry‐based learning (IBL) at three Australian universities, which employ different models and approaches, as part of a series of investigations of the needs, circumstances and perspectives of various stakeholders (program coordinator, faculty teaching staff, the students, industry mentors, and the professional body). The focus of this paper is a discussion of salient pragmatic considerations in an attempt to conceptualize what constitutes best practice in offering industry‐based learning for higher education students in the disciplines of information systems and information technology (Asia‐Pacific Journal of Cooperative Education, 9(2), 73‐80).

The presentation will describe a cooperative inquiry project being undertaken within the School of Management and Marketing, Faculty of Business and Law. This project involves both HRM and Management academics and was commenced in February 2008 with the broad aim of developing an ongoing teaching and learning dialogue within these discipline areas to enhance teaching and learning.
The project is also aimed at enabling individuals and unit teams to develop and pursue their own priorities in teaching and learning and align these with the goals and objectives of the Faculty and University.
In the presentation we will describe the scope, nature and methods of the inquiry and the outcomes of the project to date. One major outcome to date has been a comprehensive review of all the units within the HRM and Management majors. This review has, in turn, lead to the initiation of four further projects.
These include an activity to benchmark the School’s HRM and Management units against universities in Australia and overseas; a literature review entitled ‘Linking practice, research and the scholarship of teaching’; a project that seeks to integrate individual and institutional needs; and an action research project to capture the process of change within the Management and HRM team. These four projects will be described briefly in the presentation.

This paper studies the finite-time consensus tracking control for multi-agent networks. The time-varying control input and the velocity of the leader is unknown to any follower. Only the position of the leader is known to its neighbors. We first propose a new finite-time multiple-surface sliding mode observer to estimate the leader's velocity. It is seen that the estimation error of the observer can converge to zero in a finite time. Then, we prove that finite-time consensus tracking of multi-agent networks can be achieved on a new terminal sliding mode surface. Simulation results are presented to validate the analysis.

Sport and recreation students are in an ideal position to utilize an action learning approach to projects that are undertaken as part of their cooperative education experience. Action learning incorporates identifying a problem, integrating theory, determining action, and implementing and evaluating that action. This paper discusses the theoretical basis of action

Cooperative education in sport studies is considered an integral component of the professional preparation of graduates. However, whilst there is a sound body of knowledge in cooperative education, little has been published in sport studies. Through a survey of eight selected institutions, this paper examines the modes of delivery and issues involved in the practice of cooperative education in sport. Findings indicate that while there is consistency in course aims, there is a range of divergent structures, placement contexts and supervisory modes of delivery. Further research needs to focus on these aspects to ensure continued viability and relevance for such programmes.

This paper provides an insight into two cooperative education courses offered as part of three-year degree programmes in sport and recreation. Based in Auckland New Zealand, Unitec and Auckland University of Technology have been found to exemplify effective cooperative education strategies that compare favourably with current research into good practice in this field. Using a case study approach, the paper first establishes the context within which the cooperative courses operate, and then describes specific aspects of the courses that enhance student employability. The placement process, supervision, learning outcomes, assessment of learning and employment and career pathways are discussed in turn. These aspects are related back to relevant research on good practice and used to illuminate how student employability is embedded within these courses and across the degree programmes. It is concluded that students who undertake cooperative education as part of their degree programme have a competitive advantage in the employment marketplace.

There are natural synergies between action research as a method of inquiry and the practice of cooperative education. In the search to integrate theory and practice, action research is underpinned by a philosophy of experiential learning. Similarly, cooperative education is underpinned by the belief that in order to learn, there also needs to be action. The work of cooperative education students is also founded on data-based reflection is highly context based and usually collaborative; important characteristics of action research (Cardno, 2003). These similarities between action research and cooperative education provide a starting point in conceptualizing the adoption of action research for sport cooperative education projects. How can action research be integrated within cooperative education projects? This paper will discuss the theoretical basis of action research and illustrate through the use of case studies why and how action research has been utilized in cooperative education projects in sport and recreation. Sport students undertake a range of activities in the cooperative education setting. Some complete basic day to day tasks in recreation centers and with sports teams and others act as volunteers in major events. While these types of roles can fulfill desired outcomes for cooperative education program (for student, industry organization and institution), the adoption of action research can add a further dimension because it aims to create change within the setting under investigation. Through the use of cooperative education projects, students are in a unique position to frame a problem, integrate theory, determine action, and implement and evaluate that action. This paper explores how action research is used in cooperative education projects to help develop capabilities for improving practice.
