Energy, protein, calcium, vitamin D and fibre intakes from meals in residential care establishments in Australia

Residents from high level (nursing homes) and low-level care facilities (hostel) being served the three common diet texture modifications (full diet, soft-minced diet and pureed diet) were assessed. Individual plate waste was estimated at three meals on one day. Fifty-six males and 156 females, mean age 82.9+/-9.5 (SD) years, of which 139 lived in nursing homes (NH) and 76 in hostels (H) were included. Mean total energy served from meals was 5.3 MJ/day, 5.1 to 5.6 MJ/day, 95% confidence intervals (CI), in NH which was less than in H, 5.9 MJ/day (CI 5.6 to 6.2 MJ/day) (P=0.007). Protein and calcium intakes were lower in NH, 44.5g (CI 41.5 to 47.5g), 359.0mg (CI 333.2 to 384.8mg), versus 50.5g (CI 46.6 to 54.3g), 480.5mg (CI 444.3 to 516.7mg) in H (P=0.017, P<0.001 respectively). There was no difference in nutrient/energy ratios, except for protein/energy, which was higher in NH 11.7 (CI 11.3 to 12.2) than in H 9.8 (CI 9.4 to 10.3) (P<0.001). Ability to self-feed had no significant effect on nutrient intakes in NH. The self fed group (N=63) had the following nutrient intakes: energy 4.0 MJ (CI 3.6 to 4.3 MJ), protein 44.6g (CI 40.3 to 48.9g), calcium 356.9mg (CI 316.3 to 397.4mg), fibre 14.9g (CI 13.2 to 16.5g). The assisted group (N=64) had the following nutrient intakes: energy 3.9MJ (CI 3.6 to 4.2MJ), protein 46.0g (CI 40.7 to 49.6), calcium 361.9mg (CI 327.8 to 396.1mg), fibre 14.9g (CI 13.2 to 16.1g). Of NH classified as eating impaired, 36% received no assistance with feeding and had lower intakes of protein 37.8g (CI 33.0 to 42.1g) compared to those receiving some assistance 46.1g (CI 41.3 to 50.9g) (P=0.026). Reduced energy intake accounted for the differences in nutrient intakes between nursing homes and hostels, except for protein. Strategies to effectively monitor nutrient intakes and to identify those with eating impairment are required in order to ensure adequate nutrition of residents in nursing homes and hostels.

'They don't associate it with feminism' : in-service educators' conceptions of gender-inclusive curriculu

This article seeks to address significant gaps in educational policy discourses. Namely, to respond to professional development discourses that lack significant engagement with feminist perspectives, as well as to feminist discourses that fail to consider the significance of in-service education. The data reported here are drawn from a broader case study of Australian primary practitioners from 1975 who were interviewed about their enactment of gender-inclusive reform in the state of Victoria. This discussion takes as its focus the standpoint of 17 in-service educators in terms of their conceptualisation of gender inclusiveness. Three distinctive conceptions emerged in data analysis, which may be represented as three amalgams on a continuum according to a feminist perspective. Implications of this plurality of meaning for professional development are concluded.[2]

The inadequacy of Western media theory in third world internal conflicts : the case of military censorship in Sri Lanka

The literature of communication and conflict is long and deep. However, it has focused primarily on cross-border conflict in the northern hemisphere. Not much academic research has been done on intra-state conflicts in general or on Asian conflicts in particular. This research on the Sri Lankan separatist conflict contributes towards filling this void.Newspaper reports in three languages on Operation Jayasikurui (1997) as well as on the capture of Elephant Pass (2000) were analyzed by trained coders with high reliability. In-depth interviews were conducted with Sri Lankan journalists and military personnel who participated in these incidents. Triangulation sources include Sri Lanka Army materials and the Sri Lanka Government Gazette.

Results clearly show that despite stringent governmental regulations, censorship had no effect on these Sri Lankan newspapers, which employed unique cultural techniques to circumvent these restrictions. Despite their apparent divergent ethnic backgrounds, all newspaper samples are consensual in their depiction of the conflict all the time while managing to set different agendas for their individual readerships. Media regulations could not impose censorship as proposed by Western theoretical constructs. Results show no correspondence between media samples and imposition of government or military policy. The press enjoyed freedom to convey war information to the public and exhibited a distinct streak of social responsibility in their watchdog instincts.Dominant Western propaganda models and theoretical perspectives do not apply to the Sri Lankan context. Understanding the cultural dimensions is essential before theorizing on media behaviour. No particular theoretical framework from the literature could be used to make inferences. One further interesting finding suggested from this research: Internal conflict within the Asian region may have its own unique theoretical perspective. The study concludes by proposing an alternative model.

Metamemory training for memory disorders in adults with a closed head injury

The purpose of the present study was to investigate the efficacy of a memory and metamemory training program on memory performance and metamemory judgement accuracy in adults with a closed head injury. A multiple baseline across subjects design was used with six subjects. All subjects were seen at least two years post-injury. Training included general metamemory information about the nature of memory, use of a specific memory strategy to assist verbal recall (to Preview, Question, Read, State and Test- PQRST), specific metamemory information about the strategy, and a self instruction procedure (WTSC- What is the task, Select a strategy to use, Try out strategy, Check to evaluate strategy effectiveness). During the training period all subjects recalled greater than fifty percent of paragraph ideas while using PQRST. Follow-up tests showed that five of the six subjects maintained recall levels but a gradual decrease in slope was observed over eight weeks post-training. Tests of recall, recognition and metamemory judgements on Sentence and Action Tasks were used to evaluate generalisation of training. Two subjects showed improved recall and two subjects showed improved recognition performance. In addition, four subjects demonstrated greater metamemory judgement accuracy about recognition performance following training. Improved performance post-training was also observed for three subjects on the Rivermead Behavioral Memory Test and the Logical Memory subtest of the Wechsler Memory Scale-Revised, greater than that expected for repeated testing. Several factors were identified as having a role in subjects’ ability to benefit from training.

Assessing the strain experienced by managers and professional Australian footballers using an augmented job strain model

Generic models of job stress, such as the Job Strain Model (JSM), have recently been criticised for focusing on a small number of general work characteristics while ignoring those that are occupation-specific (Sparks & Cooper, 1999). However this criticism is based on limited research that has not examined the relative influence of all three dimensions of the JSM - job demand, job control and social support - and job-specific stressors. The JSM is the most commonly used model underpinning large-scale occupational stress research (Fox, Dwyer, & Ganster, 1993) and is regarded as the most influential model in the research on the psycho-social work environment, stress and disease in recent times (Kristensen, 1995). This thesis addresses the lack of information on the relative influence of the JSM and job-specific stressors by assessing the capacity of an augmented JSM to predict the strain experienced by managers and professional Australian footballers. The augmented JSM consisted of job-specific stressors in addition to the generic components of the model. Managers and professional Australian footballers represent two very different occupational groups. While the day-today roles of a manager include planning, organising, monitoring and controlling (Carroll & Gillen, 1987), the working life of a professional Australian footballer revolves around preparing for and playing football (Shanahan, 1998). It was expected that the large differences in the work undertaken by managers and professional Australian footballers would maximise the opportunities for identifying job-specific stressors and measuring the extent that these vary from one group to the next. The large disparity between managers and professional footballers was also used to assess the cross-occupational versatility of the JSM when it had been augmented by job-specific stressors. This thesis consisted of three major studies. Study One involved a survey of Australian managers, while studies Two and Three focused on professional Australian footballers. The latter group was under-represented in the literature, and as a result of the lack of information on the stressors commonly experienced by this group, an in-depth qualitative study was undertaken in Study Two. The results from Study Two then informed the survey of professional footballers that was conducted in Study Three. Contrary to previous research examining the relative influence of generic and job-specific stressors, the results only provided moderate support for augmenting the JSM with job-specific stressors. Instead of supporting the versatility of the augmented JSM, the overall findings reinforced the broad relevance of the original JSM. Of the four health outcomes measured in Studies One and Three, there was only one - the psychological health of professional Australian footballers - where the proportion of total variance explained by job-specific stressors exceeded 13%. Despite the generally strong performance of the JSM across the two occupational groups, the importance of demand, control and support diminished when examining the less conventional occupation of professional football. The generic model was too narrow to capture the highly specific work characteristics that are important for this occupational group and, as a result, the job-specific stressors explained significantly more of the strain over and above that already provided by the generic model. These findings indicate that when investigating the stressors experienced by conventional occupational groups such as managers, the large amount resources required to identify job-specific stressors are unlikely to be cost-effective. In contrast, the influence of the more situation specific stressors is significantly greater in unconventional occupations and thus the benefits of identifying these non-generic stressors are more likely to outweigh the costs. Studies One and Three identified strong connections between job-specific stressors and important characteristics of the occupation being studied. These connections were consistent with previous research and suggest that before attempting to identify job-specific stressors, researchers need to first become familiar with the nature and context of the occupation. The final issue addressed in this thesis was the role of work and non-work support. The findings indicate that the support provided by supervisors and colleagues was a significant predictor of wellbeing for both managers and professional footballers. In contrast, the level of explained strain accounted for by non-work support was not significant. These results indicate that when developing strategies to protect and enhance employee well-being, particular attention should be given to monitoring and, where necessary, boosting the effectiveness of work-based support. The findings from this thesis have been fed back to the management and sporting communities via conference presentations and peer-reviewed journals (refer pp 220-221). All three studies have been presented at national and international conferences and, overall, were well received by participants. Similarly, the methods, results and major findings arising from Studies One and Two have been critiqued by anonymous reviewers from two international journals. These papers have been accepted for publication in 2001 and 2002 and feedback from the reviewers indicates that the findings represent a significant and unique contribution to the literature. The results of Study Three are currently under review by a sports psychology journal.

The relationship between attitude and behavior : an empirical study in China

Purpose – The purpose of this paper is to examine the effects of attitude towards behavior, subject norm and perceived behavioral control (PBC) on a Chinese subject's evaluation of a tertiary education program.

Design/methodology/approach – This study adopts a 3 (country-of-origin) by 2 (location) between-group factorial design. The Theory of Planned Behavior (TPB) is used as a framework to understand the intentions of the Chinese subjects concerning their enrollment in an offshore program.

Findings – Results show that a subject's attitude towards behavior, subject norm and PBC had a significantly positive relationship with the subjects' enrollment intentions irrespective of the country-of-origin (COO) of an education program. However, results also indicate that the significance of the three components on enrollment intention is contingent on which country the offshore program is from.

Practical implications – The findings of this study can help foreign education institutions develop a good understanding of the education market in China.

Originality/value – This study is one of the few studies that have adopted the TPB, the widely used psychology theory, in the Chinese context.

Modelling biofilm growth and disinfectant decay in drinking water

A simple biofilm model was developed to describe the growth of bacteria in drinking water biofilms and the subsequent interactions with disinfectant residuals incorporating the important processes, such as attachment of free bacteria to the biofilm on a wall surface, detachment of bacteria from the biofilm, growth of biofilm bacteria with chloramine inhibition, chloramine decay in the bulk water phase, and chloramine decay due to biofilm bacteria and wall surfaces. The model is useful in evaluating the biological stability of different waters, as it can predict concentration of organic substances in water. In addition, the model can be used to predict the bacterial growth and biofilm decay in distribution systems. A model of this kind is a useful tool in developing system management strategies to ultimately improve drinking water quality.

Dietary salt loading impairs arterial vascular reactivity 1-3

BACKGROUND: Studies of sodium have shown improvements in vascular function and blood pressure (BP). The effect of chronic sodium loading from a low-sodium diet to a Western diet on vascular function and BP has been less well studied.

OBJECTIVE: The objective was to examine the effects of dietary salt intake on vascular function and BP.

DESIGN: Thirty-five hypertensive volunteers met the inclusion criteria. After a 2-wk run-in with a low-sodium diet (60 mmol/d), the participants maintained their diets and were randomly assigned to receive sequentially 1 of 3 interventions for 4 wk, with a 2-wk washout between interventions: sodium-free tomato juice (A), tomato juice containing 90 mmol Na (B), and tomato juice containing 140 mmol Na (C). The outcomes were changes in pulse wave velocity (PWV), systolic BP (SBP), and diastolic BP (DBP).

RESULTS: The difference in PWV between interventions B and A was 0.39 m/s (95% CI: 0.18, 0.60 m/s; P = 0.001) and between C and A was 0.35 m/s (95% CI: 0.13, 0.57 m/s; P = 0.01). Differences in SBP and DBP between interventions B and A were 4.4 mm Hg (95% CI: 1.2, 7.8 mm Hg; P = 0.01) and 2.4 mm Hg (95% CI: 0.8, 4.1 mm Hg; P = 0.001), respectively, and between interventions C and A were 5.6 mm Hg (95% CI: 2.7, 8.4 mm Hg; P = 0.01) and 3.3 mm Hg (95% CI: 1.5, 5.0 mm Hg; P = 0.001), respectively. Changes in PWV correlated with changes in SBP (r = 0.52) and DBP (r = 0.58).

CONCLUSIONS: Dietary salt loading produced significant increases in PWV and BP in hypertensive volunteers. Correlations between BP and PWV suggest that salt loading may have a BP-independent effect on vascular wall function. This further supports the importance of dietary sodium restriction in the management of hypertension. This trial was registered with the Australian and New Zealand Clinical Trials Registry as ACTRN12609000161224.

Association of risky alcohol consumption and accreditation in the 'Good Sports' alcohol management programme

Background Involvement in community sports clubs is often associated with high levels of risky alcohol consumption; however, developing prevention-focused interventions in these settings can be complex. We examined the association of reduced risky alcohol consumption with the implementation of the Good Sports Programme (GSP)—a programme that accredits clubs in three stages, on the basis of their implementation of alcohol-related harm reduction strategies.

Methods Using a cross section of football and cricket clubs, consumption was compared between clubs accredited at level 1, 2 or 3 of the GSP and clubs not accredited (92 clubs; 1924 individuals). Drinking above Australian guidelines for short-term risk (more than four standard drinks) on the last playing day prior to the survey and drinking at the club over the last 12 months at average levels exceeding short- and long-term risk (more than two standard drinks) guidelines were also examined.

Results Multilevel modelling indicated that higher accreditation stage (0, 1, 2, 3) was associated with a 0.79 reduction in the odds of risky consumption on the playing day; a 0.85 reduction in the odds for short-term risky drinking, and a 0.86 reduction in long-term risky drinking.

Conclusions The findings suggest that higher accreditation in the GSP is associated with reduced rates of risky alcohol use at a population level.

Modelling the health impact of environmentally sustainable dietary scenarios in the UK

BACKGROUND/OBJECTIVES:


Food is responsible for around one-fifth of all greenhouse gas (GHG) emissions from products consumed in the UK, the largest contributor of which is meat and dairy. The Committee on Climate Change have modelled the impact on GHG emissions of three dietary scenarios for food consumption in the UK. This paper models the impact of the three scenarios on mortality from cardiovascular disease and cancer.
SUBJECTS/METHODS:


A previously published model (DIETRON) was used. The three scenarios were parameterised by fruit and vegetables, fibre, total fat, saturated fat, monounsaturated fatty acids, polyunsaturated fatty acids, cholesterol and salt using the 2008 Family Food Survey. A Monte Carlo simulation generated 95% credible intervals.
RESULTS:


Scenario 1 (50% reduction in meat and dairy replaced by fruit, vegetables and cereals: 19% reduction in GHG emissions) resulted in 36 910 (30 192 to 43 592) deaths delayed or averted per year. Scenario 2 (75% reduction in cow and sheep meat replaced by pigs and poultry: 9% reduction in GHG emissions) resulted in 1999 (1739 to 2389) deaths delayed or averted. Scenario 3 (50% reduction in pigs and poultry replaced with fruit, vegetables and cereals: 3% reduction in GHG emissions) resulted in 9297 (7288 to 11 301) deaths delayed or averted.
CONCLUSION:


Modelled results suggest that public health and climate change dietary goals are in broad alignment with the largest results in both domains occurring when consumption of all meat and dairy products are reduced. Further work in real-life settings is needed to confirm these results.

Cancer survival in Australia 1992–1997 : geographic categories and socioeconomic status

Cancer Survival in Australia 1992-1997 is the first national analysis of how cancer survival varies by socioeconomic status and geographic region. It presents an analysis of five-year relative survival proportions by geographic category and socioeconomic status for persons diagnosed with cancer during the years 1992-1997.This analysis is presented by age and sex for all cancers (Excluding non-melanocytic skin cancers) combined and for the following National Health Priority Area cancers - colorectal cancer, cancer of the lung, melanoma, cancer of the breast (females only), cancer of the cervix, cancer of the prostate, and non-Hodgkin's lymphoma.This report is the third in a series of three reports on relative survival after being diagnosed with cancer. It is an important reference for all those interested in the health of Australians.

Creating spaces in higher education for marginalised Australians : principles for socially inclusive pedagogies

The Bradley Review of Australian Higher Education provided a timely reminder of the dismal performance of the nation and its higher education system in terms of the proportional representation of certain groups of Australians within the university student population. While the Australian Government has taken on the challenge of creating more university places for people from low socioeconomic status backgrounds, this article makes the case for creating spaces in higher education for marginalised Australians. Specifically, we argue that the most strategic place to begin this is with the pedagogic work of higher education, because of its positioning as a central message system in education. And it is from the centre that the greatest pedagogic authority is derived. In this paper we conceive of the pedagogic work involved in terms of belief, design and action. From these constitutive elements are derived three principles on which to build a socially inclusive pedagogy and to open up spaces for currently marginalised groups.

Use of web-conferencing software to enhance practical learning for distance students in a first-year Engineering course

BACKGROUND : For many years, Deakin University has delivered an accredited undergraduate engineering course by means of distance education. One of the chief challenges is to provide the necessary practical instruction and experience in engineering to these students. In first-year physics and first-year materials science, off-campus students normally attend on-campus lab classes either on a Saturday or as part of a residential school. However, because some students live either interstate or overseas, it is sometimes impossible for small groups of students to attend an on-campus lab class. PURPOSE : This paper investigates whether web-conferencing software can be an effective means for delivering practical classes to small groups of distance students in first-year physics and also first-year materials. METHOD : Over three semesters in 2012, we employed the Elluminate-Live! software platform to broadcast six lab practicals in first-year physics, and one practical in first-year materials engineering. The students submitted practical reports as did all the other students in each unit. The students in each unit fell into three groups: on-campus students, off-campus students who performed their practicals on-campus, and off-campus students who performed their practicals “virtually” via an Elluminate-Live! session. RESULTS : The trials showed that it is possible to broadcast both physics and materials practical classes by means of web-conferencing software. Report marks of the students performing practicals by this method were comparable to those in the other groups. CONCLUSIONS : Our experience with four initial trials in delivering practical classes over the Internet was encouraging, and showed that the concept will work if done in an effective way.
