The role of local grouping and global orientation contrast in perception of orientation-modulated textures

We explored the contribution to perception of orientation-modulated textures of visual processes selective either for orientation contrast or orientation grouping. To distinguish between these two processes we manipulated the axis of local grouping of texture elements independently of the direction of global orientation modulation. The general question posed was whether visibility of texture structure (measured as threshold for discriminating spatial-frequency of texture structure) is dependent on the magnitude of orientation contrast, strength and direction of local grouping, or some combination of the two. We demonstrated that the factor of primary importance is the amplitude of global orientation contrast rather than the presence of local grouping content. Using orientation-interleaved textures (containing two superimposed textures modulated around orthogonal orientations), we further showed that orientation single-opponent processes are a more likely candidate for detecting orientation contrast than double-opponent processes.

Ambiguities and inconsistencies in relation to the obligations of proxies under corporations law: a model for reform

This article reconsiders the important question which came to light as a result of the controversial 2002 Coles Myer annual general meeting: do directors that are appointed as proxy have an obligation to vote as directed (and indeed should they)? A recent decision of the New South Wales Supreme Court, which was subsequently approved on appeal, stands for the proposition that proxy holders are agents of the shareholders that appointed them. However, currently the Corporations Act only requires a Chairman appointed as proxy to vote as directed — not an ordinary director. This article briefly explains the present state of the law in Australia on this issue, and then explores some interesting recent judicial remarks which may suggest that ordinary directors appointed as proxy must vote as directed in order to satisfy their director’s duties (both common law and statutory) to the company. We finally outline a proposed statutory reform initiative which seeks to remove the present uncertainty in the law by introducing a blanket requirement that all proxy holders must vote as directed.

Linkages: Mabo and the sentencing of indigenous offenders

The ground breaking decision by the High Court of Australia in Mabo v Queensland (No 2) overturned the principle of terra nullis as a legal fiction. It paved the way for a reconsideration of property law. Mabo arguably has significance beyond native title and property law to other areas of the law. This article examines the 'linkage' between the decision in Mabo and the criminal law and, in particular, the punishment of indigenous persons, it addresses the following question: Can a significantly distant temporal and physical act of dispossession as was recognized in Mabo have any relevance to contemporary questions of the punishment of indigenous persons?

The use and misuse of religious language: Zionism and the Palestinians

Every discipline which deals with the land question in Canaan-Palestine- Israel is afflicted by the problem of specialisation. The political scientist and historian usually discuss the issue of land in Israel purely in terms of interethnic and international relations, biblical scholars concentrate on the historical and archaeological question with virtually no reference to ethics, and scholars of human rights usually evade the question of God. What follows is an attempt, through theology and political history, to understand the history of the Israel-Palestine land question in a way which respects the complexity of the question. From a scrutiny of the language used in the Bible to the development of political Zionism from the late 19th century it is possible to see the way in which a secular movement mobilised the figurative language of religion into a literal 'title deed' to the land of Palestine signed by God.

Misuse of the term 'stakeholder' in public relations

This article queries the relatively recent adoption of the term 'stakeholder', borrowed from the UK political and the US business management spheres, in public relations academic writing. The article concludes that these spheres use the term in a normative or ideological manner that has worrying implications. The term frames people as having a pre-existing relationship with the governments or business organisations which name them as such. This process of incorporation prejudges and potentially obscures the real relations of groups of people vis-à-vis governments and business organisations which they may wish to have nothing to do with. An argument is mounted for the defence of the term 'publics'. It is pointed out that a key originator of stakeholder theory opposes the notion of 'publics' as closer to a notion of an uncontrolled audience. The article argues that the notion of 'publics' is more fitting than the notion of 'stakeholders' if public relations is about acknowledging this uncontrollability, and to do with advising organisations about their positioning in the democratic milieu. On the other hand, the notion 'stakeholders' may be the right one if public relations is simply aimed at immediately shaping people's behaviour, irrespective of longer term and wider political implications.

Capturing the ephemeral : reflection-in-action as research

This paper considers two different methodological approaches to 'capturing' and analysing reflection-in-action in process drama teaching. Reflection-in-action, the 'thinking on your feet' that drama teachers constantly do, is ephemeral and difficult to record. In the first project discussed here, a teacher researcher study, examines the problem of representing the reflection-in-action, working around the central question of 'How can I as a researcher describe and document my reflection-in- action when working as a teacher in process drama?' The second project, an interview-based research project', developed some of the findings of the first study through a series of interviews with drama practitioners. This paper considers these methodological approaches in terms of the possibilities they provide, the limitations for the study of reflection-in- action in process drama and some possible applications of the approaches investigated for future drama research

Convergence in the gender wage gap in Australia over the 1980s: identifying the role of counteracting forces via the Juhn, Murphy and Pierce Decomposition

The paper utilises the Juhn Murphy and Pierce (1991) decomposition to shed light on the pattern of slow male-female wage convergence in Australia over the 1980s. The analysis allows one to distinguish between the role of wage structure and genderspecific effects. The central question addressed is whether rising wage inequality counteracted the forces of increased female investment in labour market skills, i.e. education and experience. The conclusion is that in contrast to the US and the UK, Australian women do not appear to have been swimming against a tide of adverse wage structure changes.

Why does the universe exist? An advaita vedantic perspective

Debates concerning causal explanations of the universe tend to be based on a priori propositions (e.g., Edwards, 1973; Smith, 1995; Swinburne, 1978). The present paper, however, addresses the metaphysical question, “Why does the universe exist?” from the perspective of a school of Hindu philosophy referred to as advaita vedanta and two of its a posteriori derived creation theories: the theory of simultaneous creation (drishti-srishti vada) and the theory of non-causality (ajata vada). Objections to advaita vedanta are also discussed. It is concluded that advaita vedanta has the potential to make a significant contribution to contemporary metaphysical debate in general and our understanding of the question, “Why does the universe exist?” in particular.

Security in the online e-learning environment

This paper addresses the role of security in the collaborative e-learning environment, and in particular, the social aspects of security and the importance of identity. It represents a case study, completed in Nov 2004, which was conducted to test the sense of security that students experienced whilst using the wiki platform as a means of online collaboration in the tertiary education environment. Wikis, fully editable Web sites, are easily accessible, require no software and allow its contributors (in this case students) to feel a sense of responsibility and ownership. A comparison between two wiki studies will be made whereby one group employed user login and the other maintained anonymity throughout the course of the study. The results consider the democratic participation and evolution of the work requirements over time, which in fact ascertains the nonvalidity of administrative identification.

Online versus postal data collection : a re-examination of the response differences using demographically matched data

Past research has identified differences between online and mail collected responses to the same survey, but differences in the demographics of respondents had also been noted making the cause of the variation unclear. In the research reported here, responses to the same questionnaire, delivered via mail and internet surveys, were demographically matched across a range of variables. This removed the impact of response differences caused by age, gender, type of product consumed and length of customer relationship. Across all the different question types and response scales, significant differences were still found between mail and online respondents, even when data were ipsatised. Notably, online respondents were far less likely to use the end-points of the scale, perhaps indicating issues with the online collection methodology. The conclusion is that the two methods of data collection can not be assumed to be directly inter-changeable, and that the method used can lead to different results if not managed carefully.

If the price is right : vagueness and values clarification in contingent valuation

The use of willingness to pay to value the benefits of health care is increasing. Much of this work assumes that health preferences are well formed or complete and readily revealed if the right question is asked in the right way. We examined this assumption, seeking evidence in a mixed-methods study that explored the meaning and implications of vague responses to a payment-scale based willingness to pay exercise.

One-half of the sample said that their vagueness meant that their maximum willingness to pay was actually greater than the amount that they had previously said it was. Thirty percent agreed that they would probably pay £10 more than a sum that they had previously said they would most definitely not pay, if they found this to be the cost of the vaccine. Interview data supported the view that the payment scale had failed to elicit the maximum willingness to pay and that some participants used the information on cost to help clarify their values, in contrast to the theory underpinning willingness to pay. The results suggest a need to consider values-clarification in health economic evaluations. Copyright © 2002 John Wiley & Sons, Ltd.

"Vox Populi, Vox Dei" - A Discussion of Dissent Within the Modern Catholic Church

The final question is: what happens in the meantime? Is it effective to dissent while conservatives hold power and clearty are not about to make any major changes? What good does it do to repeatedly bang one's head against the wall when progress is not being made? There is no one simple answer to this question, but rather several applicable ones. The first possible answer is that dissent currently does little good. The conservative hierarchy is still the dominant force within Catholicism. This hierarchy has made a habit, evidenced by the birth control debate, of pressing its conservative agenda despite popular opposition. Many people think, that if this hierarchy has not given in to the mass of opinion against it yet, dissent is futile and useless. Why argue with someone who does not listen to your argument?

Voices of the Poor: Poverty and Growth in Albania

This paper uses three waves of panel surveys at the household level to study growth and poverty in Albania over the period 2002-2004. It attempts to answer two main questions. The first question is directed at finding the micro determinants of growth and aims to expose the obstacles households face to improve their economic situation. The main focus of the analysis is to investigate the importance of health, education, and infrastructure indicators for income growth. The second question asks whether growth in Albania during the period 2002-2004 has been pro-poor. I find that there is some evidence for a convergence of incomes and a pro-poor growth, which has led to a substantial decrease in the number of people living under the poverty line. I also find that infrastructure has not been an important determinant for income mobility, and neither has health. Only the higher education of poor urban households seems to have affected prospects for growing out of poverty, and unexpectedly, the relationship is negative.

The Politics of Indonesia

"Completely revised and updated, this new edition of The Politics of Indonesia is an engaging and accessible account of the main political issues and challenges confronting Indonesia as it moves forward into the twenty-first century. Since the forced resignation of Suharto as president in 1998, Indonesia has seemingly lurched from one crisis to the next: the country's first democratically elected president, Abdurrahman Wahid was ejected from government; the army has become politically active again; and militant Islamic politics and a chauvinistic nationalism have emerged as significant forces on the political landscape. Now, with the ascension of Megawati Sukarnoputri to the presidency, Damien Kingsbury looks in detail at her style of government and the fundamental issues and concerns facing Indonesia.
The biggest question facing this heterogeneous nation seems to be whether the Republic of Indonesia will be able to hold together or whether this unitary state was just a brief moment in post-colonial history." "This book is a valuable resource for students of Asian studies, politics, and related disciplines. Likewise, it remains essential reading for those wishing to travel or do business in Indonesia and for anyone living in the strategic shadow of this important, diverse, and fragile country."

Decoding the mentoring experience : a conversation with Parker Palmer

"I think it would be awesome for everyone to be involved in a mentoring group. A lot of the time I don't think we needed 'guidance' but it was just great social interaction with people you would otherwise not have met" says one student in a University-wide First Year Initiative designed to assist students with the transition to University studies. Parker Palmer (1998, p. 21) describes mentoring as "a mutuality that requires more than meeting the right teacher; the teacher must meet the right student. In this encounter, not only are the qualities of the mentor revealed, but the qualities of the student are drawn out in a way that is equally revealing". In the Faculty of Education's 'pilot program' 54 students (25% of those enrolled in the Bachelor of Education, Primary) were randomly selected to participate. Mentoring groups consisted of six students who chose to meet volunteer staff mentors for six weeks. This paper is a reflection on the mentoring experience of one group that continues to meet regularly. The research question: What was it about the group members that allowed successful mentoring to happen? is addressed through a conversation with Parker's ideas, thereby decoding this rich mentoring experience.
