School students and part-time work: Workplace problems and challenges.

This paper uses data from a large national project on student-working to examine problems and challenges for school students working in part-time jobs. While literature has identified some potential problems and challenges, and some potential difficulties can be extrapolated from the nature of a young teenage workforce and the nature of the workplaces, these were largely absent in the two companies researched because the companies already had policies in place that addressed the potential problems. Some suggestions are made about how problems and challenges could be avoided in a wider range of adolescent workplaces.

Measuring the quality of teaching in elementary school classrooms

This paper reviews the means by which teacher quality has been measured. It considers data sources such as students, peers, experts, and examines the psychometrics and scaleproperties of teacher quality assessment instruments with respect to reliability and validity. A list of items for possible inclusion in an elementary student focussed instrument is considered, together with the potential use of such an instrument in measuring teacher quality.

Self-concept or self-esteem

Confusion exists with regard to the substantive difference between self-concept and self-esteem. In an endeavour to cast some light on this confusion two studies were conducted with 1193 preadolescents using modified versions of two commonly used instruments designed to measure self-concept and self-esteem. Exploratory factor analysis indicated that both these instruments measure specific facets of the same construct, namely self.-concept. General or global self-concept proved to be a difficult construct to measure in preadolescent students.

Rethinking the notion of culture in the national history curriculum

Major global changes are placing new demands on the Australian education system. Recent statements by the Prime Minister, together with current education policy and national curriculum documents available in the public domain, look to education’s role in promoting economic prosperity and social cohesion. Collectively, they emphasise the need to equip young Australians with the knowledge, understandings and skills required to compete in the global economy and participate as engaged citizens in a culturally diverse world. However, the decision to prioritise discipline-based learning in the forthcoming Australian history curriculum without specifically encompassing culture as a referent, raises the following question. How will students acquire the cultural knowledge, understandings and skills necessary for this process? This paper addresses this question by situating the current push for a national history curriculum, with specific reference to the study of Indigenous history and the study of Asia in Australia.

Review : Why study the media ?

Silverstone’s Why Study the Media? (hereafter WSM) is a dif� cult book to review, especially in such a short space. The content spans millennia of theoretical, analytical and historical perspectives on our media, but is none the less entirely contemporary and relevant in its focus. Silverstone’s perspective is at times elusive because the book sets out, successfully I think, to answer the question posed in the title. But it does so by raising major questions in media studies, important questions, in a way that does not imply quick and easy answers.

Microbial risk from rainwater tanks in South East Queensland

Quantitative Microbial Risk Assessment (QMRA) analysis was used to quantify the risk of infection associated with the exposure to pathogens from potable and non-potable uses of roof-harvested rainwater in South East Queensland (SEQ). A total of 84 rainwater samples were analysed for the presence of faecal indicators (using culture based methods) and zoonotic bacterial and protozoan pathogens using binary and quantitative PCR (qPCR). The concentrations of Salmonella invA, and Giardia lamblia β-giradin genes ranged from 65-380 genomic units/1000 mL and 9-57 genomic units/1000 mL of water, respectively. After converting gene copies to cell/cyst number, the risk of infection from G. lamblia and Salmonella spp. associated with the use of rainwater for bi-weekly garden hosing was calculated to be below the threshold value of 1 extra infection per 10,000 persons per year. However, the estimated risk of infection from drinking the rainwater daily was 44-250 (for G. lamblia) and 85-520 (for Salmonella spp.) infections per 10,000 persons per year. Since this health risk seems higher than that expected from the reported incidences of gastroenteritis, the assumptions used to estimate these infection risks are critically discussed. Nevertheless, it would seem prudent to disinfect rainwater for potable use.

Microassembly fabrication of tissue engineering scaffolds with customized design

Center Ltd., Shanghai This paper appears in: Automation Science and Engineering, IEEE Transactions on Issue Date: July 2008 Volume: 5 Issue:3 On page(s): 446 - 456 ISSN: 1545-5955 Digital Object Identifier: 10.1109/TASE.2008.917011 Date of Current Version: 02 July 2008 Sponsored by: IEEE Robotics and Automation Society Abstract This paper presents a novel technique to fabricate scaffold/cell constructs for tissue engineering by robotic assembly of microscopic building blocks (of volume 0.5$,times,$0.5$,times,$0.2 ${hbox{mm}}^{3}$ and 60 $mu {hbox{m}}$ thickness). In this way, it becomes possible to build scaffolds with freedom in the design of architecture, surface morphology, and chemistry. Biocompatible microparts with complex 3-D shapes were first designed and mass produced using MEMS techniques. Semi-automatic assembly was then realized using a robotic workstation with four degrees of freedom integrating a dedicated microgripper and two optical microscopes. Coarse movement of the gripper is determined by pattern matching in the microscopes images, while the operator controls fine positioning and accurate insertion of the microparts. Successful microassembly was demonstrated using SU-8 and acrylic resin microparts. Taking advantage of parts distortion and adhesion forces, which dominate at micro-level, the parts cleave together after assembly. In contrast to many current scaffold fabrication techniques, no heat, pressure, electrical effect, or toxic chemical reaction is involved, a critical condition for creating scaffolds with biological agents.

Between Two Worlds : Harry Reade, the Sydney waterfront and Cuban animation

Harry Reade (1927-1998) was an Australian waterside worker-artist who became involved with animation production through the Waterside Workers’ Federation Film Unit, in Sydney. During the early years of the Cuban Revolution, Reade contributed to Cuba’s social and cultural reform process by influencing the development of the educational sector of Cuban animation. This article examines the forces that shaped Reade and the ways in which he contributed to the use of animation as an agent of social change.

Critical social theory and transformative learning : evidence in pre-service teachers' service-learning reflection logs

This paper reports on the opportunities for transformational learning experienced by a group of pre-service teachers who were engaged in service-learning as a pedagogical process with a focus on reflection. Critical social theory informed the design of the reflection process as it enabled a move away from knowledge transmission toward knowledge transformation. The structured reflection log was designed to illustrate the critical social theory expectations of quality learning that teach students to think critically: ideology critique and utopian critique. Butin's lenses and a reflection framework informed by the work of Bain, Ballantyne, Mills and Lester were used in the design of the service-learning reflection log. Reported data provide evidence of transformational learning and highlight how the students critique their world and imagine how they could contribute to a better world in their work as a beginning teacher.

Development and use of clinical guidelines

The purpose of this chapter is to provide an overview of the development and use of clinical guidelines as a tool for decision making in clinical practice. Nurses have always developed and used tools to guide clinical decision making related to interventions in practice. Since Florence Nightingale (Nightingale 1860) gave us ‘notes’ on nursing in the late 1800s, nurses have continued to use tools, such as standards, policies and procedures, protocols, algorithms, clinical pathways and clinical guidelines, to assist them in making appropriate decisions about patient care that eventuate in the best desired patient outcomes. Clinical guidelines have enjoyed growing popularity as a comprehensive tool for synthesising clinical evidence and information into user-friendly recommendations for practice. Historically, clinical guidelines were developed by individual experts or groups of experts by consensus, with no transparent process for the user to determine the validity and reliability of the recommendations. The acceptance of the evidence-based practice (EBP) movement as a paradigm for clinical decision making underscores the imperative for clinical guidelines to be systematically developed and based on the best available research evidence. Clinicians are faced with the dilemma of choosing from an abundance of guidelines of variable quality, or developing new guidelines. Where do you start? How do you find an existing guideline to fit your practice? How do you know if a guideline is evidence-based, valid and reliable? Should you apply an existing guideline in your practice or develop a new guideline? How do you get clinicians to use the guidelines? How do you know if using the guideline will make any difference in care delivery or patient outcomes? Whatever the choice, the challenge lies in choosing or developing a clinical guideline that is credible as a decision-making tool for the delivery of quality, efficient and effective care. This chapter will address the posed questions through an exploration of the ins and outs of clinical guidelines, from development to application to evaluation.

Correlating vehicle forces and track profile

A research project was conducted at Queensland University of Technology on the relationship between the forces at the wheel-rail interface in track and the rate of degradation of track. Data for the study was obtained from an instrumented vehicle which ran repeatedly over a section of Queensland Rail's track in Central Queensland over a 6-month period. The wheel-rail forces had to be correlated with the elements of roughness in the test track profile, which were measured with a variety of equipment. At low frequencies, there was strong correlation between forces and profile, as expected, but diminishing correlation as frequencies increased.

Victoria regia's bequest to modern architecture

This paper will explore the relationship between the giant South American waterlily, the Victoria regia (today named Victoria amazonica), and the 1914 Glashaus exposition building by the German architect, Bruno Taut. Starting with a general botanical introduction of Victoria regia, the paper exposes the first European cultivation of the lily by Joseph Paxton at Chatsworth,England, in 1849. Following this initial cultivation, Paxton subsequently develops a specialist greenhouse for the plant, that later becomes the prototype for all Victoria regia greenhouses. However, from about 1860 as Victoria regia cultivation spreads to continental Europe, a greenhouse that differs from Paxton’s prototype subsequently evolves. An investigation of these later continental European greenhouses, coupled with an exposure of Taut’s own writings concerning Victoria regia, reveals startling similarities to the Glashaus, which ultimately reveals the Glashaus as directly inspired by Victoria regia.

How government agencies engage with stakeholders

As a result of the managerial reforms adopted by government agencies since the 1980s, the stakeholder approach has become more widely accepted as a strategic management tool. However it remains a difficult and demanding task for agencies to determine who their stakeholders are and to optimise interactions with them. This paper examines how government agencies identify, classify and engage with stakeholders who have competing demands, differing access to resources and the ability to exert political pressure. To do this, the stakeholder approaches of nine agencies at three levels of government in Queensland were studied. This resulted in the development of a Stakeholder Classification Model for Public Agencies which could be used to create more focused and relevant stakeholder interventions.

Democracy, participation and convergent media : case studies in contemporary online news journalism in Australia

The shift from 20th century mass communications media towards convergent media and Web 2.0 has raised the possibility of a renaissance of the public sphere, based around citizen journalism and participatory media culture. This paper will evaluate such claims both conceptually and empirically. At a conceptual level, it is noted that the question of whether media democratization is occurring depends in part upon how democracy is understood, with some critical differences in understandings of democracy, the public sphere and media citizenship. The empirical work in this paper draws upon various case studies of new developments in Australian media, including online-only newspapers, developments in public service media, and the rise of commercially based online alternative media. It is argued that participatory media culture is being expanded if understood in terms of media pluralism, but that implications for the public sphere depend in part upon how media democratization is defined.
