Policy, preparation and prevention : proactive minimisation of student plagiarism

Countless cases of plagiarism are detected across the Australian higher education sector each year. Generally speaking, policy and other responses to the issue focus on punitive, rather than on educative, measures. Recently, a subtle shift is discernable. As well as ensuring appropriate consequences for plagiarists, several universities are beginning to formalise the inclusion of learning and teaching strategies in anti-plagiarism related policy and practice, as well as paying closer attention to the communication of unambiguous definitions of plagiarism. This article outlines one example of the emerging educative approach and details the ways in which this approach has been implemented across an entire university. The necessity of evidence-based evaluation of approaches to reducing plagiarism in higher education is discussed.

Policy, preparation, prevention and punishment: one faculty's holistic approach to minimising plagiarism

Most Australian universities have made attempts of various kinds to address plagiarism. Some have responded in recent times with a primary focus on catching and punishing plagiarists, often assisted by computer software packages. Others have taken a more holistic approach incorporating foci on policy, assessment regime and student preparation and education as well as on ensuring appropriate consequences for plagiarists. This paper outlines one example of the latter approach in one Australian university faculty and details the outcomes in terms of policy recommendations and resources to support the approach. The necessity of evidence-based evaluation of attempts to reduce plagiarism in higher education is argued.

Community-based study on knowledge, attitude and practice on the mode of transmission, prevention and treatment of the Buruli ulcer in Ga West District, Ghana

Buruli ulcer disease (BUD), a devastating tropical disease caused by Mycobacterium ulcerans, occurs in more than 80% of the administrative districts of Ghana. To elucidate community perceptions and
understanding of the aetiology of BUD, attitudes towards Buruli patients and treatment-seeking behaviours, we conducted a survey with 504 heads of households and seven focus group discussions in Ga West District, Ghana. Although 67% of participants regarded BUD as a health problem, 53% did not know its cause. Sixteen per cent attributed the cause to drinking non-potable water, 8.1% mentioned poor personal hygiene or dirty surroundings, and 5.5% identified swimming or wading in ponds as a risk factor. About 5.2% thought that witchcraft and curses cause BUD, and 71.8% indicated that BU sufferers first seek treatment from herbalists and only refer to the hospital as a last resort. The main
reasons were prospects of prolonged hospital stay, cost of transport, loss of earnings and opportunity associated with parents attending their children’s hospitalization over extended period, delays in being
attended by medical staff, and not knowing the cause of the disease or required treatment. The level of acceptance of BUD sufferers was high in adults but less so in children. The challenge facing health workers is to break the vicious cycle of poor medical outcomes leading to poor attitudes to hospital treatment in the community. Because herbalists are often the first people consulted by those who contract the disease, they need to be trained in early recognition of the pre-ulcerative stage of Buruli lesions.

Prevention of type 2 diabetes in a primary health care setting interim results from the Greater Green Triangle (GGT) Diabetes Prevention Project

Although clinical trials have shown that lifestyle modifications reduce the risk of type 2 diabetes, translating lessons from trials to primary care remains a challenge. The aim of the study was to evaluate efficacy and feasibility of primary care-based diabetes prevention model with modest resource requirements in rural Australia. Three hundred and eleven subjects with at least a moderate risk of type 2 diabetes participated in a combined dietary and physical activity intervention. Clinical measurements and fasting blood samples were taken at the baseline and after intervention. After 3 months intervention, total (change −3.5%, p < 0.001) and LDL cholesterol (−4.8%, p < 0.001) plasma levels as well as body mass index (−2.5%, p < 0.001), weight (−2.5%, p < 0.001), and waist (−1.6%, p < 0.001) and hip (−2.7%, p < 0.001) circumferences reduced significantly. A borderline reduction was found in triglyceride levels (−4.8%, p = 0.058) while no changes were observed in HDL cholesterol (+0.6%, p = 0.525), glucose (+0.06%, p = 0.386), or systolic (−0.98%, p = 0.095) or diastolic (−1.06%, p = 0.134) blood pressure levels. In conclusion, a lifestyle intervention improved health outcomes – especially obesity and blood lipids – in a population at high risk of developing type 2 diabetes. Our results suggest that the present model is effective and feasible to carry out in primary care settings.

Obesity prevention programs demand high-quality evaluations

Obesity prevention programs are at last underway or being planned in Australia and New Zealand. However, it is imperative that they are well-evaluated so that they can contribute to continuous program improvement and add much-needed evidence to the international literature on what works and does not work to prevent obesity. Three critical components of program evaluation are especially at risk when the funding comes from service delivery rather than research sources. These are: the need for comparison groups; the need for measured height and weight; and the need for sufficient process and context information. There is an important opportunity to build collaborative mechanisms across community-based obesity prevention sites to enhance the program and evaluation quality and to accelerate knowledge translation into practice and policy.

Depression, anxiety and stress in women following acute coronary syndrome: implications for secondary prevention

Objective
To document incidence of depression, anxiety, and stress in women more than 6 months following an acute coronary syndrome.

Design
Participants were identified from a coronary care unit database. The Depression Anxiety Stress Scales 21 (DASS 21) was sent to potential participants via postal survey.

Setting
A metropolitan teaching hospital in Melbourne, Australia.

Participants
The cohort of women was aged between 55 and 70 years. They had been admitted to hospital with a diagnosis of acute coronary syndrome (ACS) between 6 and 14 months prior to participating in this study.

Main outcome measures
Scores on Depression, Anxiety, and Stress Scale (DASS 21).

Results
Of the 117 posted questionnaires, 39 women with a mean age of 63 (S.D. 4.97) responded to the survey, representing a response rate of 33.3%. Most participants scored within normal levels of depression (66.7%), anxiety (60.5%), and stress (70.3%), however, mild to extremely severe levels of each construct (33.4%, 39.6%, and 29.7%, respectively) were found.

Conclusions
The reporting of elevated levels of depression, anxiety and stress in a subset of women more than 6 months following an ACS event underscores the importance of ongoing screening for risk factors impacting on psychological well-being and the inclusion of this information in education and counseling strategies in both the inpatient and outpatient settings. Based on these pilot data, consideration of a screening system in the immediate post discharge period for women at risk and an education or support service are recommended.

Prevention of type 2 diabetes by lifestyle intervention in an Australian primary health care setting : Greater Green Triangle (GGT) Diabetes Prevention Project

Background
Randomised controlled trials demonstrate a 60% reduction in type 2 diabetes incidence through lifestyle modification programmes. The aim of this study is to determine whether such programmes are feasible in primary health care.

Methods
An intervention study including 237 individuals 40–75 years of age with moderate or high risk of developing type 2 diabetes. A structured group programme with six 90 minute sessions delivered during an eight month period by trained nurses in Australian primary health care in 2004–2006. Main outcome measures taken at baseline, three, and 12 months included weight, height, waist circumference, fasting plasma glucose and lipids, plasma glucose two hours after oral glucose challenge, blood pressure, measures of psychological distress and general health outcomes. To test differences between baseline and follow-up, paired t-tests and Wilcoxon rank sum tests were performed.

Results
At twelve months participants' mean weight reduced by 2.52 kg (95% confidence interval 1.85 to 3.19) and waist circumference by 4.17 cm (3.48 to 4.87). Mean fasting glucose reduced by 0.14 mmol/l (0.07 to 0.20), plasma glucose two hours after oral glucose challenge by 0.58 mmol/l (0.36 to 0.79), total cholesterol by 0.29 mmol/l (0.18 to 0.40), low density lipoprotein cholesterol by 0.25 mmol/l (0.16 to 0.34), triglycerides by 0.15 mmol/l (0.05 to 0.24) and diastolic blood pressure by 2.14 mmHg (0.94 to 3.33). Significant improvements were also found in most psychological measures.

Conclusion
This study provides evidence that a type 2 diabetes prevention programme using lifestyle intervention is feasible in primary health care settings, with reductions in risk factors approaching those observed in clinical trials.

Mental health promotion and socio-economic disadvantage: lessons from substance abuse, violence and crime prevention and child health

Issue addressed: Mental health promotion aimed at populations with low socio-economic status (SES) may benefit by investigating prevention strategies that effectively address related child and adolescent problems.
Methods: Evidence from a number of literature reviews and program evaluations was synthesised. First, the impact of SES on development from childhood to adulthood is considered in light of research on substance
abuse, violence, crime, and child development problems. Second, evaluations of interventions are reviewed to identify those that have shown outcomes in research studies (efficacy) or in real-world settings (effectiveness) in reducing developmental problems associated with low SES. Low SES is measured in different ways including low levels of education and/or income or definitions that combine several variables into a new indicator of low SES.
Results: Factors associated with low SES are also associated to varying extent with the development of violence and crime, substance abuse and child health problems. Interventions that address underlying determinants of low SES show strong efficacy in decreasing adolescent crime and violence and effectiveness in improving child health outcomes. Although there is limited efficacy evidence that substance abuse prevention can be effectively addressed by targeting low SES, programs designed to improve educational pathways show some efficacy in reducing aspects of adolescent substance use.
Conclusion: Mental health promotion strategies can draw on the approaches outlined here that are associated with the prevention of child and adolescent problems within low SES communities. Alternatively, such interventions could be supported in mental health promotion policy as they may assist in preventing related problems that undermine mental health.

School and anaemia prevention: current reality and opportunities - a Tanzanian case study

Iron deficiency anaemia is highly endemic in rural areas of Tanzania and in many developing countries. Its prevention among school children requires greater dissemination of knowledge of anaemia among children, teachers, parents and the general community. Associated improvements in the hygienic status of domestic and school environments are also often required. One-hundred-and-thirty-one anaemic children, 90 parents and 76 teachers were interviewed to ascertain their understanding of anaemia. Most children and parents had little knowledge of the symptoms, causes and prevention of anaemia. In addition to their iron-deficient diets, more than half of the children went to school without something to eat at breakfast and during school hours. However, parents and teachers were willing to work together to provide meals for the children. Poor sanitation in the children's homes and in schools was a little recognized factor which could pose a serious risk of anaemia. In addition, inadequate sanitation facilities and poor quality of physical environment prevailed both in the children's homes and in schools. The findings suggest the need for the establishment of a health-promoting schools network to provide a comprehensive framework for health promotion in schools as well as in homes in Tanzania and in other developing countries. Schools can be an ideal setting to positively influence a community's health status. Partnerships among teachers, parents and the wider community are required to identify, prioritize and ameliorate health problems.

CHD and stroke : Scotland`s pandemics also need co-ordinated and vigorous primary prevention programmes

Further reductions in the incidence and mortality from CHD and stroke in Scotland will be largely dependent upon changes in the three major risk factors – cholesterol, blood pressure and smoking. Vigorous and co-ordinated primary prevention programmes are therefore required. This paper outlines the main elements of such a prevention programme starting in the Scottish Borders. It considers the three major risk factors and discusses local action within high risk groups and within the population at large for each. The importance of considering environmental changes and social supports for change are emphasised, and because of this, the key role of local authorities and other local partners. Suggestions for action at the national level to encourage and support the growth of such programmes across Scotland are given.

Meat consumption among 18-month-old children participating in the Childhood Asthma Prevention Study

Objective: To document meat consumption among 18-month-old children, for use in refining population dietary assessment methods and dietary guidance for young children.

Design: A secondary analysis of data collected in 1998-2000 from the 18 months follow up of the Childhood Asthma Prevention Study: an intervention trial of omega-3 oil supplementation and house-dust mite reduction, from birth to five years.

Subjects and setting: Pregnant women whose unborn children had an atopic family history were recruited from antenatal clinics of six hospitals in western Sydney. Carers of 429 18-month-old children (80% response) satisfactorily completed three-day weighed food records.

Main outcome measures: Mean and median intakes per day and portion sizes of various meats and meat products.

Statistical analyses: T-tests for comparing gender differences; Pearson correlation and one-way analysis of variance for relationships between meat and nutrient intake.

Results: During the recording period 94% of the children ate meat. McDonald's Chicken McNuggets^TM, beef mince, and beef sausages were the most frequently consumed meats. Median portion sizes ranged from 20-50 g, and were considerably smaller than 'usual' portions specified on food frequency questionnaires in common use. Higher meat diets in this age group were not associated with higher intakes of iron or zinc per MJ.

Conclusion: The marginally low intakes of iron and zinc in this age group could be improved by greater use of cuts of red meat appropriately prepared for toddlers.

Healthy eating, activity and obesity prevention: a qualitive study of parent and child perceptions in Australia

Preventative health strategies incorporating the views of target participants have improved the likelihood of success. This qualitative study aimed to elicit child and parent views regarding social and environmental barriers to healthy eating, physical activity and child obesity prevention programmes, acceptable foci, and appropriate modes of delivery. To obtain views across a range of social circumstances three demographically diverse primary schools in Victoria, Australia were selected. Children in Grades 2 (aged 7–8 years) and 5 (aged 10–11 years) participated in focus groups of three to six children. Groups were semi-structured using photo-based activities to initiate discussion. Focus groups with established parent groups were also conducted. Comments were recorded, collated, and themes extracted using grounded theory. 119 children and 17 parents participated. Nine themes emerged: information and awareness, contradiction between knowledge and behaviour, lifestyle balance, local environment, barriers to a healthy lifestyle, contradictory messages, myths, roles of the school and family, and timing and content of prevention strategies for childhood obesity. In conclusion, awareness of food ‘healthiness’ was high however perceptions of the ‘healthiness’ of some sedentary activities that are otherwise of benefit (e.g. reading) were uncertain. The contradictions in messages children receive were reported to be a barrier to a healthy lifestyle. Parent recommendations regarding the timing and content of childhood obesity prevention strategies were consistent with quantitative research. Contradictions in the explicit and implicit messages children receive around diet and physical activity need to be prevented. Consistent promotion of healthy food and activity choices across settings is core to population prevention programmes for childhood obesity.
