Graphitization of Small Carbonate Samples for Paleoceanographic Research at the Godwin Radiocarbon Laboratory, University of Cambridge

A new radiocarbon preparation facility was set up in 2010 at the Godwin Laboratory for Palaeoclimate Research, at the University of Cambridge. Samples are graphitized via hydrogen reduction on an iron powder catalyst before being sent to the Chrono Centre, Belfast, or the Australian National University for accelerator mass spectrometry (AMS) analysis. The experimental setup and procedure have recently been developed to investigate the potential for running small samples of foraminiferal carbonate. By analyzing background values of samples ranging from 0.04 to 0.6 mg C along with similar sized secondary standards, the setup and experimental procedures were optimized for small samples. “Background” modern 14C contamination has been minimized through careful selection of iron powder, and graphitization has been optimized through the use of “small volume” reactors, allowing samples containing as little as 0.08 mg C to be graphitized and accurately dated. Graphitization efficiency/fractionation is found not to be the main limitation on the analysis of samples smaller than 0.07 mg C, which rather depends primarily on AMS ion beam optics, suggesting further improvements in small sample analysis might yet be achieved with our methodology.

Visual Literacy Standards in Higher Education: New Opportunities for Libraries and Student Learning

Visual literacy is essential for 21st century learners. Across the higher education curriculum, students are being asked to use and produce images and visual media in their academic work, and they must be prepared to do so. The Association of College and Research Libraries has published the Visual Literacy Competency Standards for Higher Education, which for the first time, outline specific visual literacy learning outcomes. These Standards present new opportunities for libraries to expand their role in student learning through standards-based teaching and assessment, and to contribute to campus-wide collaborative efforts to develop students’ skills and critical thinking with regard to visual materials.

Beliefs about the causes of weight change in the Australian population

OBJECTIVE: To describe self-reported weight change and beliefs about the causes of weight change and to examine whether these vary by sex and weight status.
DESIGN: This cross-sectional population study examined data from the 1995 Australian National Health and Nutrition Surveys.
SUBJECTS: A total of 10 624 randomly-selected adults provided data.
MEASURES: Objectively measured height and weight, perceptions of current weight status, self-reported weight change over the past year, and reasons for weight change.
RESULTS: Thirty-five percent of participants reported a weight gain in the last 12 months, with females, and those already overweight more likely to report a recent increase in weight. Approximately one in five participants reported a recent weight loss. Those who had recently gained weight were more likely to perceive themselves as overweight regardless of actual weight status. Commonly reported reasons for weight gain included a change in physical activity level (52% males and 35% females) and a change in the amount of food/drink consumed (30% males, 27% females). Similar reasons were given for weight loss.
CONCLUSIONS: Findings of widespread reported weight gain, particularly among those already overweight, suggest Australia's obesity epidemic may be worsening. Strategies are urgently required to better inform individuals about the factors impacting on their weight in order to prevent further weight gain.

Energy density of foods and beverages in the Australian food supply: influence of macronutrients and comparison to dietary intake

Objectives: The energy density (ED) of the diet is considered an important determinant of total energy intake and thus energy balance and weight change. We aimed to compare relationships between ED and macronutrient content in individual food and beverage items as well as population diet in a typical Western country. Design: Nutrient data for 3673 food items and 247 beverage items came from the Australian Food and Nutrient database (AusNut). Food and beverage intake data came from the 1995 Australian National Nutrition Survey (a 24-h dietary recall survey in 13 858 people over the age of 2). Relationships between ED and macronutrient and water content were analysed by linear regression with 95% prediction bands. Results: For both individual food items and population food intake, there was a positive relationship between ED and percent energy as fat and negative relationships between ED and percent energy as carbohydrate and percent water by weight. In all cases, there was close agreement between the slopes of the regression lines between food items and dietary intake. There were no clear relationships between ED and macronutrient content for beverage items. Carbohydrate (mostly sucrose) contributed 91, 47, and 25% of total energy for sugar-based, fat-based, and alcohol-based beverages respectively. Conclusions: The relationship between ED and fat content of foods holds true across both population diets and individual food items available in the food supply in a typical Western country such as Australia. As high-fat diets are associated with a high BMI, population measures with an overall aim of reducing the ED of diets may be effective in mediating the growing problem of overweight and obesity.

A study of organizational effectiveness for national olympic sporting organizations

This study applies the competing values approach (CVA) of organizational effectiveness to a sample of nonprofit Australian national Olympic sporting organizations (NOSOs). The purpose of the study was to determine the psychometric properties of the subscales developed within each of the four quadrants composing the CVA. Two hundred eightynine constituents from 10 NOSOs participated in this study. Initial factor analysis resulted in six of the eight theoretically derived cells in the CVAeach yielding one reliable factor. These were Flexibility, Resources, Planning, Productivity, Availability of Information, and Stability. The other two cells, Skilled Workforce and Cohesive Workforce, each produced a two-factor structure. To understand the relationship between these manifest factors (cells) and organizational effectiveness, a confirmatory factor analysis was conducted, which revealed that the rational-goal model, comprising Productivity and Planning, was the critical determinant of effectiveness in NOSOs.

Private protected areas? Assessing the suitability for incorporating conservation agreements over private land into the National Reserve System : a case study of Victoria

All Australian governments are committed to the establishment of a  comprehensive, adequate and representative system of conservation  reserves. Many of the most threatened species and communities throughout Australia occur mainly or wholly on private land. A range of mechanisms has been developed to achieve conservation on private land. This article  assesses the legal security, permanence and management intent of such mechanisms in Victoria, in relation to protected area criteria. The  implications of this analysis for the Australian National Reserve System and landowners with these mechanisms on their properties are discussed.

Attaching unit costs to Australia`s national survey of mental health and wellbeing

Background: In mental health, policy-makers and planners are increasingly being asked to set priorities. This means that health economists, health services researchers and clinical investigators are being called upon to work together to define and measure costs. Typically, these researchers take available service utilisation data and convert them to costs, using a range of assumptions. There are inefficiencies, as individual groups of researchers frequently repeat essentially similar exercises in achieving this end. There are clearly areas where shared or common investment in the development of statistical software syntax, analytical frameworks and other resources could maximise the use of data.

Aims of the Study: This paper reports on an Australian project in which we calculated unit costs for mental health admissions and community encounters. In reporting on these calculations, our purpose is to make the data and the resources associated with them publicly available to researchers interested in conducting economic analyses, and allow them to copy, distribute and modify them, providing that all copies and modifications are available under the same terms and conditions (i.e., in accordance with the `Copyleft' principle). Within this context, the objectives of the paper are to: (i) introduce the `Copyleft' principle; (ii) provide an overview of the methodology we employed to derive the unit costs; (iii) present the unit costs themselves; and (iv) examine the total and mean costs for a range of single and comorbid conditions, as an example of the kind of question that the unit cost data can be used to address.

Method: We took relevant data from the Australian National Survey of Mental Health and Wellbeing (NSMHWB), and developed a set of unit costs for inpatient and community encounters. We then examined total and mean costs for a range of single and comorbid conditions.

Results: We present the unit costs for mental health admissions and mental health community contacts. Our example, which explored the association between comorbidity and total and mean costs, suggested that comorbidly occurring conditions cost more than conditions which occur on their own.

Discussion: Our unit costs, and the materials associated with them, have been published in a freely available form governed by a provision termed `Copyleft'. They provide a valuable resource for researchers wanting to explore economic questions in mental health.

Implications for Health Policies: Our unit costs provide an important resource to inform economic debate in mental health in Australia, particularly in the area of priority-setting. In the past, such debate has largely been based on opinion. Our unit costs provide the underpinning to strengthen the evidence-base of this debate.

Implications for Further Research: We would encourage other Australian researchers to make use of our unit costs in order to foster comparability across studies. We would also encourage Australian and international researchers to adopt the `Copyleft' principle in equivalent circumstances. Furthermore, we suggest that the provision of `Copyleft'-contingent funding to support the development of enabling resources for researchers should be considered in the planning of future large-scale collaborative survey work, both in Australia and overseas.

Fiscal responsibility and Australian Commonwealth, State and Territory government budgets

The government sector in Australia has seen the introduction of accrual accounting principles in recent years. However, this process has been complicated by the presence of two alternative financial reporting frameworks in the form of a) the Government Finance Statistics (OFS) uniform framework and b) the accrual accounting rules specified in Australian professional accounting standards, principally AAS 31. While a variety of cash and accrual based measurements are available pursuant to these frameworks, there has been no prescription of the manner in which the alternative measures should be presented. This paper presents the findings from a case study of the 2005-06 annual budgets prepared by the Australian Commonwealth government and the governments of the six Australian States and the two Australian Territories. The study examined the headlined financial outcome (general government sector budget surplus or deficit) announced in the budget papers of the nine governments. Findings indicate the adoption of varying measurement bases and a consequent lack of inter-government comparability. A number of variations to the measurements prescribed in the accounting frameworks were also observed. The paper analyses these government budget surplus and deficit numbers in the context of fiscal responsibility, the Commonwealth government's Charter of Budget Honesty and the AASB's current GAAPIGFS Convergence project.

Responding to terrorism through networks at sites of critical infrastructure : a case study of Australian airport security networks

The importance of effective multilateral security networks is widely recognised in Australia and internationally as being essential to facilitate the large-scale sharing of information required to respond to the threat of terrorism. Australian national security agencies are currently constructing networks in order to bring the diverse national and international security agencies together to achieve this. This paper examines this process of security network formation in the area of critical infrastructure protection, with particular emphasis on airport security. We address the key issues and factors shaping network formation and the dynamics involved in network practice. These include the need for the networks to extend membership beyond the strictly defined elements of national security; the integration of public and private ‘nodes’ in counter-terrorism ‘networks’; and the broader ‘responsibilisation’ of the private sector and the challenges with ‘enabling’ them in counter-terrorism networks. We argue that the need to integrate public and private agencies in counter-terrorism networks is necessary but faces considerable organisational, cultural, and legal barriers.

The rise and fall of management: undergraduate engineering management education in Australia

The modern disciplines of engineering and management are inextricably linked. Frederick Taylor, Henry Gantt and Henri Fayol are engineers whose names are also part of the history of the theory and practice of management. As far back as 1968 it was identified that, “In all phases of practice in the profession the technical work is coupled, to a greater or lesser extent, with engineering management.” For more than 20 years the call had been increasing for an improvement in the preparation of engineering graduates in the area of management skills. In 1989 the IEAust created the task force on management engineering with the goal of formulating a policy for management education in engineering undergraduate courses. In 1990, the Council of the IEAust approved the Policy on Management Studies in Engineering Undergraduate Courses that said, “From January 1991 the Institution will require at least 5% management content in all professional engineering undergraduate courses and that the total of all management and management related components rises to the vicinity of 10% by 1995.” A 1999 analysis of engineering programs showed that the Policy had been applied with enthusiasm by about one-third of the engineering schools, fairly well in another third, remaining responses were ineffectual. Around the same time, revisions to the IEAust accreditation requirements de-emphasised the importance of management studies, mentioning it only as a subset of ‘professional practice’. By 2004 the IEAust stage 1 competency standards for professional engineers mentioned ‘management’ in only three of 79 indicators of competency. In 2002, the IEAust established the Centre for Engineering Leadership and Management. In December 2005 CELM established a working group, “…for improving the business and management content of undergraduate courses. It appears that it’s back (about 20 years) to the future for Australian undergraduate engineering management education.

Mapping cultural dimensions in Australian sporting organisations

No research focusing on sport has yet provided a method of charting cultureʼs potential dimensions. The aim of this study was to redress this gap by identifying a set of dimensions that could describe the cultures of Australian sporting organisations. The population for this study included Australian National Sport Organisations (NSOs), State Sport Organisations (SSOs) and clubs participating in national league competitions. Eight sport organisations formed the sample. Data were collected via 24 in-depth interviews. This study revealed 12 dimensions and 68 sub-dimensions of culture, which may be used to begin the process of mapping sport cultures. These results reveal some unique sport dimensions with no single existing dimensional model that captures the collective elements revealed in this study. The unique dimensions revealed in this study include “Rituals”, “Symbols”, “Size”, “History and tradition”, with support for these dimensions found within the sub-dimensional codes. This suggests that the dimensions recorded here might provide a useful launching pad for future studies on sport culture.

The potential for communities of practice to underpin the National Training Framework

This report is an evaluation of the sixteen pilot projects that were funded to form Communities of Practice in the VET sector in 2001, as part of the Reframing the Future program. The major theme emerging from this evaluation study is that Communities of Practice in the vocational education and training (VET) sector in Australia have the potential to accelerate, intensify, enrich and enhance the implementation of the national training system.

An index of diet and eating patterns is a valid measure of diet quality in an Australian population

Diet indices represent an integrated approach to assessing eating patterns and behaviors. The aim of this study was to develop a comprehensive food-based dietary index to reflect adherence to healthy eating recommendations, evaluate the construct validity of the index using nutrient intakes, and evaluate this index in relation to sociodemographic factors, health behaviors, risk factors, and self-assessed health status. Data were analyzed from adult participants of the Australian National Nutrition Survey who completed a 108-item FFQ and a food habits questionnaire (n = 8220). The dietary guideline index (DGI) consisted of 15 items reflecting the dietary guidelines, including dietary indicators of vegetables and legumes, fruit, total cereals, meat and alternatives, total dairy, beverages, sodium, saturated fat, alcoholic beverages, and added sugars. Diet quality was incorporated using indicators relating to whole-grain cereals, lean meat, reduced/low fat dairy, and dietary variety. We investigated associations between the DGI score, sociodemographic factors, health behaviors, chronic disease risk factors, and nutrient intakes. We found associations between the DGI scores and sex, age, income, area-level socioeconomic disadvantage, smoking, physical activity, waist:hip ratio, systolic blood pressure (males only), and self-assessed health status (females only) (all P < 0.05). Higher DGI scores were associated with lower intakes of energy, total fat, and saturated fat and higher intakes of fiber, β-carotene, vitamin C, folate, calcium, and iron (P < 0.05). This food-based dietary index is able to discriminate across a variety of sociodemographic factors, health behaviors, and self-assessed health and reflects intakes of key nutrients.

The use of scoring rubrics to determine clinical performance in the operating suite

Summary : This research evolved out of the need to examine the validity and inter-rater reliability of a set of performance-based scoring rubrics designed to measure competencies within the operating suite.

Method : Both holistic and analytical rubrics were developed aligned to the ACORN Standard [Australian College of Operating Room Nurses Standard NR4, 2004. ACORN Competency Standards for Perioperative Nurses: Standard NR4: The Instrument Nurse in the Perioperative Environment. Australian College of Operating Room Nurses Ltd, Adelaide] and underpinned by the Dreyfus model (1981). Three video clips that captured varying performance of nurses performing as instrument nurses in the operating suite were recorded and used as prompts by expert raters, who judged the performance using the rubrics.

Results : The study found that the holistic rubrics led to more consistent judgments than the analytical rubrics, yet the latter provided more diagnostic information for intervention purposes. Despite less consistency, the Analytical Observation Form had sufficient construct validity to satisfy the requirements of criterion referencing as determined by the Item Separation Index (Rasch, 1960), including high internal consistency and greater inter-rater reliability when average ratings were used.

Conclusion : The study was an empirical investigation of the use of concomitant Analytical and Holistic Rubrics to determine various levels of performance in the operating suite including inter-rater reliability. The methodology chosen was theoretically sound and sufficiently flexible to be used to develop other competencies within the operating suite.
