Photobactericidal effects of TiO 2 thin films at low temperatures - A preliminary study

The efficacy of TiO ₂ photocatalysis for the destruction of pathogenic bacteria has been demonstrated by a number of groups over the past two decades. Pathogenic bacteria represent a significant hazard for the food and drink industry. Current practices in this industry dictate that rigorous sanitizing regimes must be regularly implemented resulting in lost production time. The incorporation of a TiO ₂ antibacterial surface coating in this setting would be highly desirable. In this paper we report a preliminary study of the efficacy of a TiO ₂ coating, doped with the lanthanide, neodymium, at low temperature conditions such as those utilised in the food and drink sector. The rapid destruction of Staphylococcus aureus, a common foodborne pathogen, was observed using TiO ₂ films coated to glass and steel substrates. 

The media and the development of the tourism industry during the 20th and 21st centuries: an analysis of four noteworthy cases

The aim of this paper was to explore the role of the media within the context of tourism, specifically with regard to how the media has influenced the activities and perceptions of the tourism sector. In this paper, the term ‘media’ is referred to as mass communication, specifically with regard to newspapers, magazines and broadcasting. It is important to gain a better understanding of the ways in which the media has interacted with the tourism sector, as this information can provide practitioners and academics with insights as to how the media can best be employed to benefit stakeholders of the tourism industry. Lessons can be learned from the past so that the experience gained from it can contribute to best practice in the future. In this way, strategies can be developed to minimise the vulnerability of the tourism sector to damaging or erroneous portrayals of it and its activities in the media.
The case study method was used to explore the role of the media within the context of tourism. Four case studies provided insights on this topic. The four case studies were selected based on their diversity, within the context of the tourism sector, and because they covered a considerable period of time. These variables provided the researchers with a wide-ranging perspective on the topic.
The paper firstly focuses on the 1920’s Waiters’ Strike in the resort town of San Sebastián, Spain, and discusses the role of the media in relation to this event. The second case investigates the use of the media as a destination-marketing tool and reflects on an early manipulation of this process by the German authorities in the documentary Olympia, a film produced for the summer Olympics in 1936. The third case study reports on the manner in which the media has created tensions between connoisseurs of fine food and drink and hospitality industry professionals, and its subsequent implications on service quality. The final case investigates the role of the media in reducing demand for hospitality services in Melbourne on New Year’s Eve 2000.
Through an analysis of these diverse, but important case studies, it can be seen that the media has had, and continues to have, an impact on the development of the tourism industry in both positive and negative ways. The limitations of this research are discussed and recommendations are made for further research that will assist in developing a more comprehensive typology of the media’s role in tourism.

Rethinking policy options for industry:Appropriateness of policies for industry and UK farming and food

Purpose - Studies the implementation of lean supply and partnership relationships in the UK food and farming industry to assess if these types of interventions are effective. Design/methodology/approach - Reviews the challenges affecting the UK supply chain for red meat. Describes the initiatives that were set up to develop a lean supply chain management approach and examines their application in the UK pig and beef industries. Assesses if these changes benefited all participants in the supply chains. Uses semi-structured interviews with key actors in each stage of the supply chain to do this, identifying the power relations within the supply chains and how these affected the outcomes for those participating in the chain. Findings - Concludes that lean initiatives were appropriate for the pig industry but were of limited value for the beef industry. Even within the pig industry, highlights that benefits were not shared equally, with producers, in particular, losing out. Lastly, points out that lean supply chain management is unlikely to be appropriate operationally and commercially in all circumstances in one industry. Argues for a differentiated policy approach and sets out a framework which enables decision makers to select industrial policy options. Research limitations/ implications - Describes the analysis and the framework developed from it. Originality/value - Assesses the effectiveness of lean supply chain management.

Food Labels, Autonomy and the Right (Not) to Know

Food labelling has been overlooked in the emerging body of literature concerning the normative dimensions of food and drink policies. In this paper, I argue that arguments normally advanced in bioethics and medical ethics regarding the “right to know” and the “right not to know” can provide useful normative guidelines for critically assessing existing and proposed food labelling regimes. More specifically, I claim that food labelling ought to respect the legitimate interests and the autonomy of both consumers who seek knowledge about their food in order to make informed dietary choices and consumers who prefer to remain ignorant about the contents and effects of their food in order to avoid the emotional and psychological harm, or more simply the loss of enjoyment, which may result from receiving that information.

Natural food and beverage flavour enhancers

Flavour enhancers are of great importance to the food industry and the consumer, in terms of achieving strong, balanced and preferred product flavour. The understanding and use of flavour enhancers can help to avoid excessive use of individual ingredients such as salt or specific character impact flavours. This chapter first discusses savoury flavour enhancement through the use of ingredients rich in amino acids and 5’nucleotides. It later includes the potential role of peptides and Maillard derived compounds. The role of volatile flavour compounds in the enhancement of salt and sweet taste is also discussed.

Assessing the impact on chronic disease of incorporating the societal cost of greenhouse gases into the price of food: an econometric and comparative risk assessment modelling study

Objectives To model the impact on chronic disease of a tax on UK food and drink that internalises the wider costs to society of greenhouse gas (GHG) emissions and to estimate the potential revenue. Design An econometric and comparative risk assessment modelling study. Setting The UK. Participants The UK adult population. Interventions Two tax scenarios are modelled: (A) a tax of £2.72/tonne carbon dioxide equivalents (tCO2e)/100 g product applied to all food and drink groups with above average GHG emissions. (B) As with scenario (A) but food groups with emissions below average are subsidised to create a tax neutral scenario. Outcome measures Primary outcomes are change in UK population mortality from chronic diseases following the implementation of each taxation strategy, the change in the UK GHG emissions and the predicted revenue. Secondary outcomes are the changes to the micronutrient composition of the UK diet. Results Scenario (A) results in 7770 (95% credible intervals 7150 to 8390) deaths averted and a reduction in GHG emissions of 18 683 (14 665to 22 889) ktCO2e/year. Estimated annual revenue is £2.02 (£1.98 to £2.06) billion. Scenario (B) results in 2685 (1966 to 3402) extra deaths and a reduction in GHG emissions of 15 228 (11 245to 19 492) ktCO2e/year. Conclusions Incorporating the societal cost of GHG into the price of foods could save 7770 lives in the UK each year, reduce food-related GHG emissions and generate substantial tax revenue. The revenue neutral scenario (B) demonstrates that sustainability and health goals are not always aligned. Future work should focus on investigating the health impact by population subgroup and on designing fiscal strategies to promote both sustainable and healthy diets.

Innovative approaches For enhancing the flow of funds into the Benefit Sharing Fund of the International Treaty on Plant Genetic Resources for Food and Agriculture: an evaluation of options

This report assesses the implications and revenue-generating potential of options for reform of the International Treaty on Plant Genetic Resources for Food and Agriculture in the context of the structure of the global seed industry and the emerging landscape of plant variety innovation for different crops. The implementation of these options would require modifications of Treaty and provisions of the Standard Material Transfer Agreements to alter the nature of payment obligations related to different categories of products, the payment rates under different options and the coverage of crops in Annex-I to the Treaty.

Maternal self-efficacy regarding children's eating and sedentary behaviours in the early years : Associations with children's food intake and sedentary behaviours

Introduction. This cross-sectional study aimed to describe parents' views regarding self-efficacy to influence children's eating and sedentary behaviours at two time points in early childhood, and to examine associations between these views and children's eating and sedentary behaviours.

Methods. Mothers of 1-year (n=60) and 5-year-old children (n=80) were recruited through Maternal and Child Health Centres and kindergartens in Victoria, Australia. Mothers reported children's dietary intake, television viewing and perceptions of their self-efficacy regarding children's eating and sedentary behaviours.

Results. Overall, 5-year-old children consumed significantly more energy-dense food and drink and spent significantly more time viewing TV/DVD and video. Mothers of 1-year-olds were significantly more likely to report they felt confident to limit child's consumption of non-core foods/drinks, and to limit screen access (p<0.001). Measures of maternal self-efficacy were directly associated with 5-year-old children's water (p<0.05), and fruit and vegetable consumption (p<0.005), and with 1-year-old children's vegetable consumption (p<0.05), and were inversely associated with cordial and cake consumption (p<0.05). Maternal self-efficacy to limit viewing time was inversely associated with screen-time exposure in both age groups (p<0.01).

Conclusion. This study suggests that mother's self-efficacy regarding limiting non-core foods/drinks and limiting screen-time exposures may decline during the first few years of a child's life. Higher maternal self-efficacy was associated with children having more obesity protective eating and sedentary behaviours at both ages. Interventions to support the development of healthy lifestyle behaviours may be most effective if they target mothers' self-efficacy in these domains early in their child's life.

Supermarket Healthy Eating for Life (SHELf): protocol of a randomised controlled trial promoting healthy food and beverage consumption through price reduction and skill-building strategies

Background: In the context of rising food prices, there is a need for evidence on the most effective approaches for promoting healthy eating. Individually-targeted behavioural interventions for increasing food-related skills show promise, but are unlikely to be effective in the absence of structural supports. Fiscal policies have been advocated as a means of promoting healthy eating and reducing obesity and nutrition-related disease, but there is little empirical evidence of their effectiveness. This paper describes the Supermarket Healthy Eating for LiFe (SHELf) study, a randomised controlled trial to investigate effectiveness and cost-effectiveness of a tailored skill-building intervention and a price reduction intervention, separately and in combination, against a control condition for promoting purchase and consumption of healthy foods and beverages in women from high and low socioeconomic groups.
Methods/design: SHELf comprises a randomised controlled trial design, with participants randomised to receive either (1) a skill-building intervention; (2) price reductions on fruits, vegetables and low-joule soft drink beverages and water; (3) a combination of skill-building and price reductions; or (4) a control condition. Five hundred women from high and low socioeconomic areas will be recruited through a store loyalty card program and local media. Randomisation will occur on receipt of informed consent and baseline questionnaire. An economic evaluation from a societal perspective using a cost-consequences approach will compare the costs and outcomes between intervention and control groups.
Discussion: This study will build on a pivotal partnership with a major national supermarket chain and the Heart Foundation to investigate the effectiveness of intervention strategies aimed at increasing women’s purchasing and consumption of fruits and vegetables and decreased purchasing and consumption of sugar-sweetened beverages. It will be among the first internationally to examine the effects of two promising approaches - skill-building and price reductions - on diet amongst women.
