Drawing on Weber’s rationalisation theory and feminist critiques of the consumption-production literature, this thesis describes the impacts and changes in dietary practices that have occurred in households as a result of limited or constrained time available for family food provisioning, and how these changes can be understood as a product of contemporary Australian policy, cultural and food landscapes. It adopts feminist ethnography and household food strategies as important methodological innovations to forge a culturally informed account of convenience-orientated dietary practices in family households within contemporary Australian society. The data were collected from 15 Brisbane family households between January 2002 and August 2006. The thesis argues that dietary practices observed in ‘time-poor’ households have evolved as solutions to the problem of time scarcity by women whose role has traditionally been to feed families. The ‘solutions’ are shaped by the resources to which households have access, and ideas and traditions about family care, food and its responsibility, and available alternative options. Change is observed in diets, menus, source of prepared meals and prepared ingredients, but also organisation of food provisioning and distribution of workload. Also being reshaped is the role of food in the expression of cultural identity, commensality and, in the family setting, the transmission of food skills and knowledge. An analysis that critiques the usefulness of ‘speeding up’ domestic food provisioning as a viable and sustainable solution to the retention of the family meal is drawn, highlighting the problematic nature of persistent nostalgic interpretations of commensal eating patterns in culinary, food activism, sustainability and nutrition discourses. In the absence of a coherent moral philosophy for guiding current public health policy and practice, Kittay’s public ethic of care is proposed as a suitable model. A key challenge for future research is to ensure that household level sociocultural analysis continues to enrich broader debates in food policy and public health.

This study is designed to examine comparative advertising as a viable advertising strategy in today's competitive business environment. Frequency and use of comparisons by the selected key industries and advertising agencies are investigated. Analysis is conducted to determine similarities and differences between firms who elect or avoid comparative advertising. Based on an analysis of the findings, certain conclusions are presented. The industry leader is not likely to use comparative advertising in most industries. Firms that are fourth or smaller in market share are most likely to use comparisons. However, the smallest firms, in terms of dollar sales volume, are least likely to use comparative advertising.

The recent increase in the number of black working women has meant that time has become an even more precious commodity in the majority of households with working women than before. Growth in women’s participation in the labour market has tended to stimulate the demand for time-saving goods and services, especially convenience foods to cope with time pressure in the preparation of meals. South African working women are moving towards the consumption of convenience foods as they become busier, managing both work and household chores, and also having more disposable income. This study aimed at gathering ideas and insight on the acceptability and use of convenience foods by black women employed by government in Mpumalanga. It investigated the consumption frequency of convenience foods in four categories, the contributing sensory attributes and the influence of resources, the socio-cultural environment and the occasion or situation on the acceptability and use of convenience foods. Food outlets used by black working women for the purchase of convenience foods were also identified. To elicit relevant information, a quantitative research design and survey techniques using structured questionnaires, with open and closed-ended questions were used to gather information. With the literature review and the objectives of the study in mind, 200 working women employed by government at the government Boulevard complex in Nelspruit formed the sample group. The Statistical Package for the Social Sciences Version 9.0.1 (SPSS), a computer statistical data programme. Descriptive and inferential statistics facilitated data analysis. From the discussion and interpretation of the results of the sample survey it was clear that black working women tend to either use certain types of convenience foods in the four convenience food categories less frequent (not more than twice in a week) or to use certain types of convenience foods, frequently (3 -4 times in a week or 5 - 6 times and every day of the week). The results showed clearly that there were relatively high proportions of working women (more than 56, 5% of the respondents) who were low users of almost each type of the convenience foods in the four convenience food categories except for baked products, cereal dishes, fried/grilled/roasted meat, and fully prepared refrigerated salads in category A; meat stews and fully prepared vegetable dishes in category B; breakfast cereals, vegetable salad ingredients, instant soups and instant sauces in category C and cleaned/pealed ready to cook vegetable items, pre-cut frozen vegetables, crumbed frozen fish and crumbed frozen or refrigerated meat portions in category D. Moreover, the findings confirmed that the sensory attributes, appearance, texture, smell and taste and flavour were considered very important in the acceptability and use of convenience foods. Resources, the socio-cultural environment and occasion or situation were also seen to have had a positive influence on the acceptability and use of convenience foods by the black women employed by government in Mpumalanga who participated in the survey. The study has contributed to the limited literature on the use of convenience foods especially by black working women. Moreover, food product developers and retailers will gain insight into the provision of convenience foods relevant to the needs and desires of time pressed consumers. / Dissertation (MConsSci)--University of Pretoria, 2009. / Consumer Science / unrestricted

The food industry has an essential role in society and in the global economy. Nowadays, modernlifestyle demands convenience, which is driving the development of the food sector. This isparticularly evident with convenience food, especially ready-made meals, industrially preparedfood, which only requires a short preparation time at home by consumers, but has very complexand diverse supply chains and is associated with a range of sustainability issues. Therefore, theaim of this research is to evaluate the environmental, economic and social sustainability in theready-made meals sector with the focus on the UK market. A life cycle approach has been used forthese purposes, using life cycle assessment (LCA) as the tool for the environmental analysis, lifecycle costing (LCC) for the economic aspects and social sustainability indicators (SI) for the socialissues. Different types of ready-made meal from different cuisines have been considered, includingthe British, Italian, Chinese and Indian. The highest environmental impacts are found for the Italian and Indian cuisines, while Chinesemeals are environmentally most sustainable, followed by the British. At the sectoral level, theresults suggest that from ‘cradle to retailer’ the British ready-made meal sector contributes 4.45 Mtof CO2 eq. annually, which represents ~4% of the GHG emissions of the food and drink sector and~1% of the UK GHG emissions. Of this, 3.16 Mt of CO2 eq. is emitted by chilled and 1.28 Mt of CO2eq. by the frozen ready-made meals. The total life cycle costs at the sectoral level from ‘cradle tograve’ are estimated at £2.1 bn, with the chilled ready-made meals market contributing £1.42 bnand the frozen £676 million. The life cycle costs from ‘cradle to retailer’ are £1.02 bn, with the valueadded of £958 million. The common environmental and cost hotspot for all the meals studied is rawmaterials. In particular, the meat, fish and seafood are the greatest contributors. For theenvironmental impacts, the manufacturing and distribution stages are also important, while theconsumption stage is the largest contributor to the costs. The major social aspects are the foodrelated health issues and food security, in particular food affordability. In the supply chainagriculture, wholesale and retailers show high risk for indicators such as wages and employmentwhile the manufacturing presents high risk in fatal injuries. The study also shows that consumer choices play an important role for the economic andenvironmental impacts; therefore, educational programmes and better communicational strategiesshould be implemented by the industry, the government and consumers groups. Moreover, toensure a sustainable development of the ready-made meals sector, future policies and industrialinitiatives should consider a life cycle approach including relevant economic, environmental andsocial aspects.

This study tested the utility of the theory of planned behavior (TPB) to explain adolescent fast-food consumption among 349 high school adolescents. Subjective norms were further investigated to identify how parents and friends influenced adolescent fast-food consumption. Study participants completed a paper-based questionnaire measuring adolescent attitude, subjective norms for parents and friends, perceived behavioral control, and behavioral intention. Path analysis revealed that TPB explained adolescent fast-food behavioral intention to consume fast food. The model identified parent subjective norms had the strongest relationship with adolescent behavioral intention to consume fast food. Parent norms differed across age and grade in high school. Older adolescents perceived more approval for eating fast food than younger adolescents. Theoretical and practical implications are discussed.

This thesis aims to find out trade-offs between security, privacy and convenience when it comes to smart locks. If users know about security and privacy risks associated with smart locks and how they perceive the trade-offs, if they think that the security and privacy risks are worth it for some added convenience. In this project both a literature review and online survey was used to gather information. The results are that there are conveniences with smart locks but that they come with potential security and privacy risks. That overall users seems to know that there are potential security and privacy risks and users seem to think that any potential security and privacy risks are worth taking for the sake of convince.
