An authorization policy management framework for dynamic medical data sharing

In this paper, we propose a novel feature reduction approach to group words hierarchically into clusters which can then be used as new features for document classification. Initially, each word constitutes a cluster. We calculate the mutual confidence between any two different words. The pair of clusters containing the two words with the highest mutual confidence are combined into a new cluster. This process of merging is iterated until all the mutual confidences between the un-processed pair of words are smaller than a predefined threshold or only one cluster exists. In this way, a hierarchy of word clusters is obtained. The user can decide the clusters, from a certain level, to be used as new features for document classification. Experimental results have shown that our method can perform better than other methods.

Sharing good teaching practice: Practical strategies to integrate ICT into the classroom

Situated in regional areas of Victoria, a group of 16 primary and secondary teachers participated in an intensive program of professional development designed to assist them in embedding lCT into their classroom practice. Most teachers made significant changes to their teaching practice becoming risk-takers and problem solvers.This paper reports on the strategic innovations introduced by the teachers including training, preparation, curriculum planning, software evaluation and selection, classroom management strategies, cooperative learning strategies and embedded assessment tasks. The paper will explore the ways these innovations responded to a variety of constraints including limited resources, time and support.

Sharing and speaking about African music : professional development with Swaziland primary school teachers

The teaching and learning of Indigenous African music is characterised as a holistic integrated experience where music, dance and theatre are inseparable, seen as an integral part of culture. The transmission of this experience is absorbed through participation in cultural activities from childhood in the community. In African societies, both traditional and contemporary, musical arts education and the understanding of culture are fundamental to life, community and society. It is through musical arts, that Africans embrace spiritual, emotional, material and intellectual aspects and knowledge of both the individual and the community. This paper reports on an in-service program (August 2006) offered at the Centre for Indigenous African Instrumental Music and Dance Practices (CIIMDA), Pretoria, South Africa. For the purpose of this paper, the one week professional development course undertaken by generalist primary school teachers from Swaziland is highlighted and proves worthy for these teachers to implement what they learnt in the classroom. As a position paper, I contend that the understanding and participation in indigenous cultural musical arts practices, enlightens learners about their cultural heritage and further enriches their understanding of African music and dance that can be adopted, adapted and applied to primary schools in Swaziland. This paper summaries some key findings of interview data from ten participants in relation to the intensive program. By offering such in-service professional development programs, teachers are able to reach their wider communities where they will continue to share and speak about African music, dance and culture.

Gender, emotion and aggression in the workplace

This study explores emotion and aggressive behaviour in a male-dominated
organisation, an Australian police force. The study examines the extent to which men’s negative emotions are directly associated with their reported experience of aggressive behaviour. One hundred and fifty-nine male participants answered a questionnaire which measured: the intensity of negative feelings, whether or not the intensity of such negative feelings was directly associated with the experience of aggression, and the magnitude of the aggressive behaviour.

Information sharing between heterogeneous uncertain reasoning models in a multi-agent environment : a case study

The issue of information sharing and exchanging is one of the most important issues in the areas of artificial intelligence and knowledge-based systems (KBSs), or even in the broader areas of computer and information technology. This paper deals with a special case of this issue by carrying out a case study of information sharing between two well-known heterogeneous uncertain reasoning models: the certainty factor model and the subjective Bayesian method. More precisely, this paper discovers a family of exactly isomorphic transformations between these two uncertain reasoning models. More interestingly, among isomorphic transformation functions in this family, different ones can handle different degrees to which a domain expert is positive or negative when performing such a transformation task. The direct motivation of the investigation lies in a realistic consideration. In the past, expert systems exploited mainly these two models to deal with uncertainties. In other words, a lot of stand-alone expert systems which use the two uncertain reasoning models are available. If there is a reasonable transformation mechanism between these two uncertain reasoning models, we can use the Internet to couple these pre-existing expert systems together so that the integrated systems are able to exchange and share useful information with each other, thereby improving their performance through cooperation. Also, the issue of transformation between heterogeneous uncertain reasoning models is significant in the research area of multi-agent systems because different agents in a multi-agent system could employ different expert systems with heterogeneous uncertain reasonings for their action selections and the information sharing and exchanging is unavoidable between different agents. In addition, we make clear the relationship between the certainty factor model and probability theory.

A logical framework for knowledge sharing in multi-agent systems

The issue of knowledge sharing has been an important topic in multi-agent research. Knowledge sharing leads to that agents analyze, judge and synthesize the told information so as to make agents’ own knowledge. To match these applications, this paper builds a logical framework for knowledge sharing among agents. We develop a multimodal logic for reasoning about both agents’ knowledge and told information. For formalizing the relationship between knowledge and told information, we present a framework of semantics, with respect to which a sound and complete proof theory is given.

The various means by which organisations control or avoid emotion

The purpose of this paper is to examine, from the perspective of change recipients, how organisational change shapes emotional responses and the typical ways in which organisations respond to emotionality. Through the influence of change strategists' role and role obligations, interpersonal influence, and use and abuse of power, organisations seek to control or avoid emotion. The final section of the paper explores the implications of these issues for management of change and offers change leaders alternative paths to dealing with emotional responses during times of organisational change.

Overt and covert aggression and negative emotion in the workplace

This study explores indirect and direct aggression, emotion and aggressive behaviour in a male-dominated organisation, an Australian police force (APF). The study examines women’s experience of direct/overt and indirect/covert aggression in the workplace and whether their experience of aggression is higher in the presence of men than of other women; also, whether men’s experience of negative emotions is directly associated with their reported aggressive behaviour towards women. The study formed part of a larger project in which 144 women and 159 men employed in the APF completed a questionnaire. Results are discussed in terms of their theoretical and practical implications, and suggestions are made for future research into this important but difficult subject area.

Aversive sexism and emotion regulation in a masculine organization

This study explores aversive sexism as an extension of Dovidio and Gaertner's (2004) recent notion of aversive racism. In this study, we investigate the presence of aversive sexism by examining relationships between emotional experience and emotion regulation in a masculine organization, an Australian Police Force ('APF').

Emotion, reason and tradition : essays on the social, poltical and economic thought of Michael Polanyi

This collection of essays demonstrates the continuing importance of the work of Michael Polanyi for the understanding, not only of the great events of the 20th century, but also of the problems that face us in the 21st century. Polanyi moved liberalism away from a negative, sceptical and rationalist basis towards an acceptance of trust, tradition and faith in transcendent values. His conception of the free society is not one merely of doing as one pleases nor vacuously 'open', but one of individual and communal self-dedication to those values and ideals.These essays, authored by a distinguished international and interdisciplinary panel of invited contributors, examine Polanyi's specific insights in the theory of knowledge, the nature and source of social order and the philosophy of economics and science and draw relevant comparisons between Polanyi and related thinkers such as Popper, Hayek and Mises. This book shows the sources of Polanyi's ideas and his distinctive contribution to philosophy generally, to social and political thought and to economics.
