The purpose of this paper is to present an approach for continuous acoustic condition monitoring of transformers based on chromatic principles for abstracting information on individual acoustic events as well as secondary trends in the behaviour of the events.

The potential benefits of condition monitoring of high-value transformer equipment are explored, and an approach based on chromatic information abstraction is illustrated and discussed.

Tracking of large numbers of complex and variable individual acoustic events over time using a chromatic approach appears to offer a means for remote operators to evaluate mechanical transformer tap changer condition in a traceable manner.

The condition monitoring is retrofittable and non-intrusive, and the approach may be applied generically for combining condition indicators for overall health-checking. A complex system behaviour may be operationally simplified without discarding the complexity.

This study aims to examine Victorian primary school parents’ perspectives about a potential school-provided lunch program (LP).

An online cross-sectional survey was conducted in Victoria, Australia, in 2022 to explore parents’ perceptions regarding the lunch menu, funding source, amount willing to pay, frequency of meals and special dietary needs of a school-provided LP.

Over half of parents (57% out of 359) said they would allow their child to participate in a school LP, 34% were unsure and only 9% said they would not. The opportunity for hot cooked lunches at school and the perceived convenience for parents were the top two reasons for favouring such a program. Fifty-eight percent were in favour of hybrid-type funding from both the government and parents. The most preferred amount to pay per meal was AUD5-6 (43%), followed by AUD3-4 (25%). Parents expected meals to be healthy and made from whole food and cater to the special dietary and cultural needs of their children. They also expected enough time to be allocated so children could eat and enjoy the meals.

To the best of the authors’ knowledge, this is the first study to explore Victorian parents’ perceptions regarding the above aspects of a school-provided LP. The findings suggest that parents are receptive to a school-provided LP; they, however, did have several expectations regarding the menu and time for eating. These findings provide important directions for designing future school-provided LPs at primary schools in Australia.

This study aims to gain an understanding from parents and teachers about the types of food provision practices and venues, and the food-related policies and rules in primary schools in Australia; and investigate any differences in the presence of policies and rules based on the school location and school type.

Data were collected via two online surveys from August 2019 to March 2020. Descriptive statistics were employed to analyse quantitative responses. Respondents' written responses to food-related policies were categorised into groups.

The two most common food provision services were canteen and lunch order services (mentioned by 72 and 55% of respondents, respectively). Of the 425 respondents whose schools had a canteen (parents and teachers together), 62% reported their school implements a healthy school canteen policy. Significantly more parents compared to teachers, and more respondents from government schools compared to non-government schools stated that their school had implemented such a policy. Approximately half of the respondents (47%) stated their school had implemented other food-related policies and/or rules. These policies or rules belonged to four categories: avoiding certain foods, avoiding food sharing, avoiding food packages and promoting healthy eating.

This study shows the disparities exist in implementing food-related policies among primary schools in Australia. Nutrition promoters and policy planners should consider these results and find the best mechanisms to minimise the gaps in policy implementation.

During the COVID-19 pandemic people worldwide in the same household spent more time together and school children engaged in remote learning throughout extended lockdowns and restrictions. The present study aimed to explore parents' perceptions of their involvement and enjoyment in food-related interactions with their children during coronavirus disease 2019 (COVID-19)-associated lockdowns/restrictions and changes in their children's food intake, especially children's lunches during the remote learning period.

Data from parents (n = 136) were collected via an online survey in 2020. Parents' responses to closed-ended questions were analysed via descriptive statistics and open-ended responses were analysed thematically.

Most parents (62%) reported that they interacted more with their school-aged (5–17 years) children about food during COVID-19 compared to pre-pandemic times. These interactions included cooking, menu planning, eating, conversations around food, and gardening. Most parents (74%) prepared meals with their children during the pandemic and most of them (89%) reported that they enjoyed it. Most parents (n = 91 out of 121) perceived that their children's lunches during remote learning were different to when attending school in person and these changes included eating hot and home-cooked food and more elaborate meals.

This study sheds important insights into a sample of Australian parents' food-related interactions with their school-aged children during the COVID-19 pandemic and associated lockdowns and parents' observations and perceptions of changes in the children's food intake during the remote learning period.

This paper aims to develop a novel risk analysis model that uses both participatory and computerized techniques to capture and model the dynamic of risk impact propagation and interaction pattern.

In this research, an integrated model, applying modified participatory method and novel dichotomize procedure in the perspectives of social network topological analysis, is developed.

Based on the analysis output, it is found that; (i) the risk propagation is characterized by its dynamic and non-linear impact pattern, and (ii) the risk interaction is distinguished based on the degree of connectedness between various risks.

This research assumes that the risk impact propagation and interaction pattern within the risk network are static. Further research is required to analyze the risk network in dynamic circumstances.

This research contributes in delivering practical tools that could potentially provide a further path for developing mitigation strategy and policies that seek to address the complexity of risk phenomena, and thus enhance community resilience.

This research reveals some underlying patterns of how the risk impact propagation and interaction pattern are structured. Thus, it can help decision-makers make formal arrangements of particular urban infrastructure (UI) governance visible toward building risk plan and mitigation strategies.

This research contributes to filling the risk management knowledge gap. It is suggested that analyzing risk using a network approach is suited to capture the intricate processes that shape the complexity of UI risk structural network. By validating the model, this research shows the applicability and capability of the model to improve both the RA accuracy and decision making effectiveness towards risk mitigation plan and strategy.

Targeting public–private partnership (PPP) rental retirement villages, the purpose of this paper is to bring forward the solution of insufficient research in a non-competitive guarantee (a restrictive agreement) towards the compensation and guarantee costs in consideration of benefit redistribution if the governments are unable to keep the promise on guarantee provision.

Real option principles are applied to assess the public–private investment proportions and the expected return rates of the private sector in a non-competitive guarantee and analyse their effects on the public–private benefit and risk allocations as well as the success of the project. Instead of granting direct capital support, this research accomplishes the compensation of non-competition guarantee by adjusting the project benefit distribution ratios between the government and the private sector to achieve the option value of the guarantee. An empirical example with alternative scales, which is developed from an existing rental village in Geelong, is used to numerically verify the research process.

The results illustrate that the option value of the non-competition guarantee plays an important role in supporting the implementation of the PPP rental retirement village projects. The option value of the non-competition guarantee has a close relationship with the guarantee level and the government guarantee cost, which is positively correlated with the guarantee level and negatively correlated with the government guarantee cost. To reduce the government guarantee cost, the government should carefully determine the public–private investment proportion, appropriately control the return rate of the private sector and approve the construction of the new project after the investment recovery of the private sector.

This research mainly focusses on the economic loss of the government due to the guarantee responsibility. Further research could be conducted to determine the guarantee level more precisely and take the social cost of the government guarantees into consideration.

This research is the first attempt to investigate the government compensation and costs of non-competition guarantee for PPP rental retirement village projects and will enhance the understanding of the nature of PPP applications. The evaluation process and the implementation of the compensation through the adjustment of benefit distribution provides a comprehensive method to analyse the non-competition guarantee of PPP projects and help the parties negotiate in good faith to agree on a method of redress.

The purpose of this paper is to understand middle class household food providers’ attitudes to the regulation of food marketing and the promotion of healthy food practices.

A cross-sectional, online questionnaire survey was administered to 3,925 urban respondents in Indonesia, Melbourne, Shanghai, Singapore and Vietnam. Cross-tabulation, confirmatory factor analyses and multiple regression analyses were employed.

Most respondents supported government communications to promote healthy eating and to a lesser extent, regulatory measures to control unhealthy food marketing. Personal values and country of residence were more strongly associated with the respondents’ views than demographic variables. Overall, strongest support for nutrition promotion and for stricter regulation of food marketing was seen in Shanghai, Indonesia and Vietnam. Broadly, two groups were identified across the region: those who held equality-nature or tradition-security-conformity personal values, who disapproved of food marketing but supported government health promotion campaigns, and, those with stronger hedonist values who held opposite views.

First, a wider range of personal values could be included in future studies to better represent Asian values. Second, changes in population views could be assessed in future longitudinal studies. Finally, future studies should include dietary assessments and the views of people from a variety of socio-economic and cultural backgrounds.

These findings suggest that health policy makers and communicators need to frame their communications to match the world views of household food providers in their countries.

The study provides confirmation of attitude-values theories within five different countries in the Asia Pacific region and demonstrates the importance of personal values and country of residence in influencing food providers’ views.

Primary schools provide continuous, intensive contact with large numbers of children starting from a young age, thus providing an appropriate setting for the promotion of healthy eating through food and nutrition education (FNE). This qualitative study explores the views of Australian primary school parents about FNE in primary schools.

In total, 19 parents of primary school children from Victoria participated in semi-structured interviews. Audio recordings were transcribed and underwent thematic analysis using Nvivo. A total of three themes emerged: FNE topics currently taught in primary schools, essential food skills and knowledge for primary school children and the importance of FNE.

Most parents thought that FNE is as important as the core subjects of primary school. Parental support for FNE, which is delivered over a prolonged period, and expanded by hands-on content such as cooking and gardening classes was evident. Parents viewed these classes as likely to improve children's food-related knowledge and healthy eating behaviours. Parents expressed appreciation for schools' emphasis on food sustainability and its alignment with school policies and practices. Parents were keen to see more sustainability included in the curriculum.

These results may have implications for curriculum developers and schools, as the findings can assist the design of food and nutrition curricula for primary schools which can empower children as well as their families to make better food-related decisions.

Australian parents' views of FNE in primary schools have been under examined.

The rising prevalence of obesity among Indian adolescents has underscored the need to develop effective strategies to reduce this epidemic. The purpose of this paper is to assess the patterns of snacking, meal consumption and fast food consumption among adolescents in private schools in Kolkata, India.

A cross-sectional, paper-based, self-administered dietary and lifestyle survey was completed by 1,026 year-nine students aged 14–16 years. Cross-tabulation analyses were performed to compare the frequencies of various dietary behaviours across gender.

The two most common episodes for snacking among respondents were while watching television (57.9 per cent) and while interacting with peers (54.1 per cent). In contrast, snacking throughout the day (8.7 per cent) and in the middle of the night (7.8 per cent) were minimally practiced by the adolescents. The most regularly consumed meal was lunch (94.6 per cent), whereas the most frequently missed meal was breakfast (14.0 per cent). Fast food was most frequently consumed as snacks (26.8 per cent) but least frequently consumed for lunch (9.2 per cent). Overall, boys exhibited more unhealthy dietary behaviours than girls.

These findings highlight the need to develop nutrition education programmes for nutritionally vulnerable adolescents which communicate the importance of regular meal consumption, reduced intake of fast food and less snacking on energy-dense, nutrient-poor foods.

This is the first cross-sectional survey to investigate patterns of snacking, meal consumption and fast food consumption amongst urban Indian adolescents.

A school canteen can serve as an important setting for nutrition and health promotion. The purpose of this paper is to describe secondary school students’ perceptions of Indian school canteens.

Convenience sampling informed the recruitment of 1,026 year 9 students from nine private schools in Kolkata, India, and data were collected through self-completion of paper-based questionnaires. Frequencies and χ² analyses were computed.

The school children reported that energy-dense, nutrient-poor foods like French fries (90.4 per cent), pizza (79.5 per cent) and cakes (69.2 per cent) were frequently available in the school canteens. However, only a few students (10.2 per cent) acknowledged the availability of nutritious foods like fruits. Only a small proportion of students were content with the nutritional quality of food supplied in the canteens (3.6 per cent), the cost of food (8.7 per cent) and availability of fresh foods like fruits (5.5 per cent). The provision of healthy foods in the school canteen was supported by two-thirds of the respondents (65.9 per cent); however, only a small proportion (18.3 per cent) supported the restriction of fried foods in school canteens.

These findings underscore the need for the design and implementation of healthy school canteen policies to foster healthy eating habits among Indian adolescents.

This is the first cross-sectional survey to investigate the views of adolescents regarding school food services in the Indian context.
