Primary mathematics practice : the Victorian position

In order to establish what constitutes current primary practice in Victoria, video and other data were collected from a stratified random sample of ten year 3 and 4 classrooms in Victoria. Three video vignettes, representing the contrasting pedagogical flows captured on the videotapes, were produced to stimulate discussion in three separate Focus Groups of randomly selected teachers, principals, and mathematics teacher educators and consultants. This paper reports on their views of what constitutes current Victorian practice in primary mathematics

High stakes principalship - sleepless nights, heart attacks and sudden death accountabilities: reading media representations of the US principal shortage

The possible shortage of applicants for principal positions is news in both Australia and abroad. We subject a corpus of predominantly US news article to deconstructive narrative analysis and find that the dominant media representation of principals' work is one of long hours, low salary, high stress and sudden death from high stakes accountabilities. However reported US policy interventions focus predominantly on professional development for aspirants. We note that this will be insufficient to reverse the lack of applications, and suggest that the dominant media picture of completely unattractive principals' work, meant to leverage a policy solution will perhaps paradoxically perpetuate the problem. This picture is also curiously at odds with research that reports high job satisfaction among principals. We suggest that there is a dominant binary of victim and saviour principal in both media and policy which prevents some strategic re-thinking about how the principalship might be different.

The successful school: a genuine trend or a statistical artifice?

Schools are increasingly being expected to make improvements based on data about students' learning outcomes. Such an expectation implies that principals, teachers and key personnel within systems can read and act upon the data available. There is evidence, however, that many people have poor understanding of statistical information, and that many factors inside and outside the school have an effect on students' outcomes. This study considers one primary school's data from statewide testing programs. Trends across time are considered as a basis for making judgments about the school's performance in improving students' learning outcomes in literacy and numeracy.

Identifying the barriers to implementing the Victorian Department of Education and Training guidelines regarding the provisions of nutrient dense food options in school canteens

Aims & rationale/Objectives : To identify barriers to the full implementation of new guidelines regarding school canteen menus launched by The Victorian Education Department in May 2004.
Methods : A self-administered questionnaire was sent to principals, business mangers and canteen managers of 13 secondary schools in South West Victoria covered by The Greater Green Triangle area (response rate 59%). The questions explored the canteen's role, operation, staffing and profits; existence and content of canteen policy; enablers and barriers to the sale of healthier foods; introduction and promotion of healthier foods; and perceived implications of banning less healthy foods.
Principal findings : The study identified several barriers to implementing healthy menus in school canteens, these being largely consistent with those found in other studies. The majority of schools reported they were making attempts to follow the guidelines for school food services, but were experiencing difficulty in proceeding to full implementation. The barriers identified through the study were student preference for less healthy options, concerns about profitability, lack of policy or its active communication and promotion at the school level and competition from other food outlets.
Discussion : There was evidence that healthy foods had not been actively promoted, suggesting that identification of student preferences as a barrier was based on perception rather than observation. The Victorian guidelines are effectively voluntary, with no accountability measures in place.
Implications : Research needs to be conducted to provide reliable and tested information about factors which impact on student choice. Schools would benefit from specialised assistance to formulate business plans for contemporary canteens selling healthy food and a clarification of government policy.

3D haptic needle insertion simulator utilising an agent based spherical voxel model

This paper describes a technique for the real-time modeling of deformable tissue. Specifically geared towards needle insertion simulation, the low computational requirements of the model enable highly accurate haptic feedback to a user without introducing noticeable time delay or buzzing generally associated with haptic surgery simulation. Using a spherical voxel array combined with aspects of computational geometry and agent communication and interaction principals, the model is capable of providing haptic update rates of over 1000Hz with real-time visual feedback. Iterating through over 1000 voxels per millisecond to determine collision and haptic response while making use of Vieta’s Theorem for extraneous force culling.

A model of business ethics

It appears that in the 30 years that business ethics has been a discipline in its own right a model of business ethics has not been proffered. No one appears to have tried to explain the phenomenon known as ‚business ethics’ and the ways that we as a society interact with the concept, therefore, the authors have addressed this gap in the literature by proposing a model of business ethics that the authors hope will stimulate debate. The business ethics model consists of three principal components (i.e. expectations, perceptions and evaluations) that are interconnected by five sub-components (i.e. society expects; organizational values, norms and beliefs; outcomes; society evaluates; and reconnection). The introduced model makes a contribution to the creation of a conceptual framework for business ethics. A few tentative conclusions may be drawn from the introduced model of business ethics. The model aspires to be highly dynamic. The ultimate outcome is dependent upon the evolution of time and contexts. It is also dependent upon and provides reference to the behaviours and perceptions of people. The model proposes business ethics to be a continuous and an iterative process. There is no actual end of the process, but a constant reconnection to the initiation of successive process iterations of the business ethics model. The principals and sub-components of the model construct the dynamics of this continuous process. They provide guidance on what and how to explore our common efforts to understand the phenomenon known as business ethics. The model provides opportunities for further research in the field of business ethics.

The small rural school principalship : key challenges and cross-school responses

This article explores the responses of school principals of small rural schools in Victoria, Australia to leadership challenges they identify as characteristic of these contexts. The research is an exercise in grounded theory building, with the focus on the principalship as it is enacted in small rural settings. The article also seeks to trace the impact of macro and meso influences on micro rural contexts. While many very positive attributes of small rural schools are evident, this article speaks to principalship engagement with contextual problems – issues concerning work intensification, role multiplicity, school viability, new regulatory funding requirements and the abandonment of equity policies in education – since there is a dearth of information in Australia at this time about how school principals confront these challenges in small rural locations. The research exposes a growing culture of creative collaborative responses to the pervasive impediments of leading small rural schools.

Rule-based dependency models for security protocol analysis

Security protocol analysis has been discussed for quite some time in the past few years. Although formal methods have been widely used to identify various vulnerabilities, mainly susceptibility to freshness attacks and impersonation, the arisen inconsistent data between principals and collusion attacks held by a group of dishonest principals have been largely ignored. Moreover, the previous methods focus on reasoning about certain security-related properties and detecting known attacks against secure message, whereas there have been insufficient efforts to handle the above hidden but powerful attacks. In this paper, we address these critical issues and prove the efficiency and intuitiveness of rule-based dependency models in defending a protocol against the attacks. This is able to provide a numerical estimation to measure he occurrence of these attacks. It will be useful in enhancing the current protocol analysis.

Mentoring in the leading across effective small schools program : the perspectives of 'critical friends'

In this chapter, I refer to the reflections of Wendy Graham and Carolyn Scott who were ‘critical friends’ or mentors working alongside school leaders in the Leading across Effective Small Schools (LAESS) program. As recently retired principals of small rural schools, the mentors offered support, encouragement and advice to LAESS participants in order to enhance collegial cross-school improvement and develop leadership skills. These perspectives provide another important dimension to this book, because a mentor or critical friend can be more objective and see the bigger picture more clearly. Mentors are removed from day-today school life, yet importantly these mentors have ‘insider’ or situated knowledge about small rural school contexts and leadership which assists current school leaders to reflect on their practice and grow as leaders. The chapter also draws on comments from mentors, which emerged in independent formal evaluations of the LAESS program conducted by Carol Oakley.
