Educational process modelling with workflow and time Petri nets : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Computer Science at Massey University, Palmerston North, New Zealand

The research presented in this thesis describes how to use workflow management technology to model educational processes with a time axis. As workflow management technology has been widely used in modelling business processes, it has the potential to model educational processes. Based upon the components of workflow, educational processes and business processes have many common features such that educational processes can be modelled with workflow management technology. In addition, owing to the importance of the time component in processes, time Petri nets have been chosen as the design language for the modelling of the educational processes. The notation of time Petri nets has been illustrated in this thesis for the educational process. In this thesis, three different educational processes have been presented and modelled with workflow management technology as well as with time Petri nets individually. Furthermore, the architecture of the educational process management system has been constructed by adopting the reference model from the Workflow Management Coalition. To show the validity of using workflow management technology in the education domain, a sub-process of an educational process has been modelled and developed with certain developing techniques. It provides the potential research direction for further research on the modelling of educational process with workflow technology associated with a time component

An empirical study of the repatriation of female managers : an emerging issue for European multinationals

In recent years, researchers have paid considerable attention to the issues of adjustment to international assignments, while comparatively little research activity has been paid to the topic of repatriation. Despite the growth in numbers of women in international management, very few studies have been conducted outside North America on the topic of repatriation of female corporate executives. This paper reports on the experiences of re-entry to home organizations and home countries by an exclusively senior sample of female international managers based in western Europe. The findings establish that the repatriation stage of an international career move may be even more stressful than expatriation. The findings also establish that female international managers experience more difficulties than their male counterparts because of their pioneering roles. The paper suggests that home-based mentors and access to networks while abroad are important factors in contributing to the successful repatriation of international managers

On Engineering Support for Business Process Modelling and Redesign

Currently, there is an enormous (research) interest in business process redesign (BPR). Several management-oriented approaches have been proposed showing how to make BPR work. However, detailed descriptions of empirical experience are few. Consistent engineering methodologies to aid and guide a BPR-practitioner are currently emerging. Often, these methodologies are claimed to be developed for business process modelling, but stem directly from information system design cultures. We consider an engineering methodology for BPR to consist of modelling concepts, their representation, computerized tools and methods, and pragmatic skills and guidelines for off-line modelling, communicating, analyzing, (re)designing\ud business processes. The modelling concepts form the architectural basis of such an engineering methodology. Therefore, the choice, understanding and precise definition of these concepts determine the productivity and effectiveness of modelling tasks within a BPR project. The\ud current paper contributes to engineering support for BPR. We work out general issues that play a role in the development of engineering support for BPR. Furthermore, we introduce an architectural framework for business process modelling and redesign. This framework consists of a coherent set of modelling concepts and techniques on how to use them. The framework enables the modelling of both the structural and dynamic characteristics of business processes. We illustrate its applicability by modelling a case from service industry. Moreover, the architectural framework supports abstraction and refinement techniques. The use of these techniques for a BPR trajectory are discussed

Report on the Survey of Role-Based Access Control (RBAC) in Practice

From literature study, we collected: (a) a set of core features of the RBAC model, according to the ANSI/INCITS 359:2004 RBAC standard, (b) implicit assumptions, (c) a set of strengths, and (d) a set of phenomena which may limit these strengths in practice. To acquire insights about these four elements and complement our initial set of strengths and phenomena, a survey was designed and launched online between June and July 2011. This report consolidates results obtained from the survey
