Full textAbstract:
The thesis performed in this research is focused on a particular type of energy system, energy systems in supermarkets. As supermarkets are high-energy using buildings, their energy system optimization has been investigated in recent years, with the main focus in the refrigeration system, which can take up to 50% of the total energy of the supermarket. However, the complexity and interconnections of the different systems increase the difficulty of the task. The aim of this work is to contribute in SuperSmart project, an EU project which main objective is to reduce the impact of the supermarket sector overall Europe, through the development of an ecolabel criteria. To simulate the energy use in supermarkets, CyberMart software is bring forward. This tool is used both to determine the parameters which have a higher impact in the supermarket energy system and perform energy representation based on those parameters. Finally, the design of the most energy efficient store is also presented. According to CyberMart, some of the most determinant parameters in the supermarket energy system are refrigeration capacities, plug in cabinets used, lights power, heating system technologies used and whether the cabinets are covered or not. Using some of these parameters plus other important characteristics from the store, two energy representations are performed. Whereas the quadratic representation provides the final results concerning heat or electricity demands with a high accuracy, the linear representation presents the increase or decrease of kWh per each parameter, enabling supermarkets owners to compare different parameters within the global system. It is concluded from these representations, which distinguish between heat recovery and floating condensing technologies, that the most important parameters in the global system are the temperature inside at winter and the refrigeration capacity. However, some unreasonable events appear, like the decline of electricity demand when the height of the building increases or the drop of heat demand with the rise of opening hours. These facts occur due to the high complexity of the global system, implying different connections between the sub-systems within CyberMart. Concerning the most energy efficient store located in Stockholm, the obtained results show the most energy efficient supermarket is composed by CO2 refrigeration and heating systems, and a R410_A air conditioning system. The optimal electricity use of each establishment size from large to small area is 382, 394, 390 and 281 kWh/m2*year respectively, with the highest values obtained in Supermarkets and Discount stores, due to their higher rate of refrigeration power per store area. Keywords: Supermarket, refrigeration system, SuperSmart, CyberMart, heating system, refrigeration capacity, plug in cabinets, lights power, heating system technology, covering of the cabinets, energy representation, heat recovery technology, floating condensing technology, air conditioning system, Discount store.

Full textAbstract:
The nature and role of workplace literacy and numeracy are the subject of considerable debate (Baker, 1998; Castleton, 2002; Gee & Lankshear, 1997; Hull, 1997; Jackson, 2000; Marr & Hagston, 2007). The debate in New Zealand, (as in many other countries), is taking place amid concerns about the adequacy of the skills of its workforce and the latter’s ability to meet future demands of everyday work and life (Tertiary Education Commission, 2008). These concerns have resulted in major investment at a national level in a Skills Strategy (New Zealand Government, 2008) with particular emphasis on improving adult literacy and numeracy levels. However, Castleton (2002) suggests that conceptualising literacy as a skill ignores the reality of workplaces which, she suggests, consist of communities of workers who engage in purposeful communication and who possess and use different skills and knowledge in complementary ways, while Hull (1997) believes that too great an emphasis is placed on literacy, particularly in low skilled work. I teach on a programme for students with limited English literacy and numeracy proficiency. A common entry point into the workforce for current and past learners from the programme is entry-level supermarket work. However there is limited information available about the literacy and numeracy pre-requisites for this type of work or the literacy and numeracy demands placed on those in employment. In seeking to contribute to the body of knowledge about low skilled work in general and entry-level supermarket work in particular, research was carried out in a large, busy, suburban supermarket. The study was underpinned by the belief that both literacy and numeracy are social practices which cannot be separated from the contexts in which they occur. It adopted an ethnographic approach and was conducted through semi-structured interviews with supermarket managers and entry-level workers/supermarket assistants; observation of assistants during induction and at work; and analysis of some significant supermarket documentation. Findings indicate that, while literacy and numeracy are generally not considered to be important pre-requisites for entry-level supermarket work, supermarket assistants are exposed to highly context-specific literacy texts and ‘embedded’ and invisible numeracy demands at induction and during parts of their working day. The findings have significance for the teaching of literacy and numeracy in vocational training programmes. They indicate that off-site programmes have an important role to play in providing a learning foundation but also point to the importance of, and need for, workplace-specific, on-the-job literacy and numeracy training.

Full textAbstract:
Background:This thesis strives to analyze aesthetic services used in supermarkets. Supermarkets facefierce competition and varied marketing dilemmas such as traditional marketing versusservice marketing. Nevertheless, encompassing elements from both traditionalmarketing, such as physical products, and service marketing, such as relationshipbuilding, supermarket management is challenging. Thus, it is crucial to understandconsumers’ perceptions for both services and products in order to satisfy their needs andwants and succeed in the market place. Therefore, this thesis offers a betterunderstanding of aesthetic elements used in supermarkets from customers’ perspective.Aim:The main purpose of this thesis is to investigate the applications of aesthetics insupermarkets. It intends to examine and theorize the consumer perceptions regardingaesthetic elements applied in supermarkets; to test the differentiation strategy insupermarkets, through the usage of aesthetic elements, from consumers’ perspective.Definitions:Aestheticization of daily life: it can be seen as the extension of art or the appreciation ofart on daily life. It suggests ‘the collapse of the distinction between high art and massculture, leveling out of symbolic hierarchies and cultural declassification’ (Featherstone,2007). It reflects onto business through its emphasis on beauty, sensory appeals,pleasure consumption etc. Analyzing aesthetic applications in supermarkets from acustomer perspective, this thesis finds out that from both companies’ and consumers’perspective, these applications are based on aestheticization of daily life.Completion and Results:Aesthetic elements used in supermarkets are identified in the content analysis anddiscussed in the empirical study through focus group interviews. It is found out thataesthetic services indeed improve customer satisfaction. However, the fierce pricecompetition limits supermarkets’ services to instrumental rather than expressiveperformance. Moreover, utilized aesthetic services in supermarkets tend to bestandardized, due to benchmarking processes, in consumers’ eyes, causing theseservices to lose their value to be differentiated.

CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICODesenvolveu-se um modelo termodinâmico para cálculo do consumo energético e do impacto ambiental (LCCP e TEWI) em sistemas de refrigeração de supermercados para três diferentes configurações (expansão direta, fluido secundário e em cascata). O modelo termodinâmico trabalha solidário com o pacote de cálculo de propriedades REFPROP e determina diversos parâmetros de funcionamento do ciclo de refrigeração, tais como o COP e a capacidade de refrigeração. O modelo simula sistemas operando com substâncias puras ou misturas delas, podendo estas ser azeotrópicas ou não-azeotrópicas. Procede-se a uma análise do tipo BIN (Intervalo) a partir de informações climatológicas anuais de cada cidade e ao cálculo do consumo anual de energia para cada intervalo considerando-se o consumo do compressor, das bombas, se for o caso específico da utilização de fluido secundário, e também o consumo energético dos expositores frigoríficos. Realizou-se, também, uma análise da carga total (inventário) do refrigerante no supermercado. Finalmente, conhecidos o consumo energético anual, a massa total de refrigerante contido no sistema e estimativa de seu vazamento anual, e outros fatores ambientais, procedeu-se ao cálculo do LCCP (Life cycle climate performance) e do TEWI (Total equivalent warming impact), em quilogramas equivalentes de CO2. Um programa computacional, com interface baseada na plataforma Visual-Basic 6.0, com aplicações para Excel, foi desenvolvido para a solução dos sistemas de equações resultantes do modelo matémático desenvolvido. Os resultados obtidos com o código computacional foram comparados com dados de campo e de outros modelos.
A thermodynamic model was developed for the evaluation of energy consumption and environmental impact (LCCP and TEWI) of supermarket refrigeration systems operating in three different configurations (direct expansion, secondary fluid and cascade). The model simulates refrigeration systems operating with pure substances or a mixture (azeotropic or non-azeotropic) of them. A BIN analysis is carried out taking into account year-round climate data for each city and the annual energy consumption, in each time interval, of each component: compressor, pumps, freezers and coolers. Refrigerant inventory was also calculated. Finally, with the annual energy consumption, total refrigerant charge, annual leakage estimate, environmental impact indicators LCCP (Life cycle climate performance) and TEWI (Total equivalent warming impact), in kilograms equivalent of CO(2), were calculated. A computational code, with interface based on Visual Basic 6.0 platform, was developed for the solution of the resulting systems of equations that form the mathematical model. Predicted results were compared with field data and with data predicted from other models.

Full textAbstract:
Over the decades the concept of green consumption has been discussed with sustainable consumption, green behavior, eco-citizenship and sustainable patterns and lifestyles. Various environmental problems like global warming, pollution, shortage of natural resources and climate change threatened the sustainability of the environment and our survival. There is an increasing demand from scholars and society for the change of human behavior to help reduce the environmental impact.
This study aims to investigate how supermarket influences the daily consumption in a sustainable way through the concept of green marketing in terms of green product management, green packaging, green promotion, green pricing, green logistics and green labeling. That means, a supermarket is not only a place to provide green products but also influence the culture of green consumption through the efforts of designing environmentally friendly facilities and strategies. In real life practice, there are constraints and challenges to encourage green consumption in the community.
Through literature review, interview and surveys, the study investigates the kinds of products and facilities which have been used in Hong Kong supermarkets and consumers’ perception and knowledge of environmentally friendly products and services. Through exploration of overseas case studies, insights on common sustainable practices were identified and how overseas’ best practices can be adopted or modified in Hong Kong were discussed. The surveys with Wellcome/Three Sixty/MarketPlace by Jasons and the general public illustrate how supermarket can promote sustainable and green consumption in Hong Kong and the progress of achievement. The study ends with suggestions on how joint-efforts from the various stakeholders in the society can facilitate green consumption. These include public participation, green initiatives of supermarkets, price incentive, promotion and government’s support to encourage pro-environmental behavior.published_or_final_version

This study focused the supermarket industry and its objective was to measure how much the existence of a program card loyalty in a supermarket, the customer loyalty to this program and the perception of value the customers have of the firm, affect the store loyalty. As many companies have been spending a great amount of money to keep their Loyalty Programs, it seems to be relevant to measure the effectiveness of this kind of program. The methodology used in this study was Linear Regression Analysis. In the regression analyses were considered the constructs: Program Perceived Value, Program Card Loyalty and Store Perceived Value as the independent variables and Store Loyalty as the dependent variable. The analysis concluded that the Loyalty Programs in supermarkets are not working as an effective loyalty tool. Firms are spending money on it that may not be justified. The Program Card Loyalty proved to have no correlation with the Store Perceived Value.
Este estudo focou na indústria de supermercados e teve como objetivo examinar o quanto os fatores referentes à existência de um programa de fidelidade em um supermercado, a fidelidade do cliente com esse programa e a percepção de valor que o cliente tem da loja, influenciam na sua lealdade à loja. Como muitas empresas têm feito um grande investimento nos Programas de Fidelidade, é certamente relevante que seja medida a efetividade desse tipo de programa. A metodologia usada foi a análise de regressão linear. Nesta análise de regressão foram consideradas as seguintes variáveis independentes: Valor percebido do programa, a Lealdade ao cartão de fidelidade da loja, o valor percebido da loja. Como variável dependente foi considerada a Lealdade à loja. A análise concluiu que os programas de lealdade em supermercados não estão funcionando como instrumentos efetivos de fidelidade e não têm relação com o Valor Percebido da Loja. O investimento das empresas nessa ferramenta não está trazendo o retorno esperado de desenvolver fidelidade no cliente.

Full textAbstract:
This thesis examines the nature of labour usage within a market-leading Australian food retail firm and the employment relations consequences of the labour usage strategies employed by the firm. Retail employment is well established as a research subject in the UK, but has received comparatively little research attention in Australia. Given that retail industry employment accounts for 15 per cent of the Australian workforce, this represents a significant oversight. Within the retail industry, the supermarket and grocery sector employs 6 per cent of the Australian workforce. The sector is dominated by two major chains and is highly competitive, with a reputation for low profit margins, mundane jobs and low pay. The sector is recognised for an employment structure that is segmented with one segment holding full-time jobs with core employment conditions and the other segment, part-time jobs with poor working conditions. The dominant theory used by scholars to explain this employment structure is the dual labour market model and later iterations such as Atkinson's flexible firm model. This research assesses the value of these models, in particular Atkinson's flexible firm model, as a representation of the labour usage strategies of a market-leading Australian food retail firm. This analysis demonstrates that, in a general sense, Atkinson's model has applicability to the labour usage strategies exhibited in food retailing. The research found that, contrary to the theories of dual labour markets, a strong internal labour market operated within the firm with short hours casual employment as the port of entry. The benefits of this practice for the organisation were flexibility in labour usage and substantial wage savings, while the negative consequences were recruitment difficulties, exacerbated by high levels of staff turnover. For the employees, the consequences depended on their position in the organisational hierarchy and their individual circumstances, but involved initially accepting limited working hours and low pay in order to gain entry into the organisation. The research undertaken for this thesis leads to the development of a revised model, the casual internal labour market model, which more accurately depicts the labour usage strategies within the case study organisation. Retail researchers argue that it is necessary to understand the dynamics of the industry in order to understand the structure of labour usage. Additionally, employment relations and retail researchers both stress the need to contextualise labour usage patterns within broader environmental constraints and supply side factors. In seeking to achieve this, this research examines business strategies, retail specific employment relations literature and the Australian employment relations context. Furthermore, this study addresses the issue of retail employment strategies at several levels within one of Australia's market-leading food retailers: corporate level, store level and at the level of individual departments within the store. In doing so, this thesis highlights the differences in labour usage between stores and between departments within the stores and thereby provides a more detailed picture of the labour use practices within food retailers.

Full textAbstract:
Purpose - The purpose of the research is to study how category management is implemented by Chinese Lianhua supermarket. Design/methodology/approach - This paper is adopted a single case study of qualitative ap-proach with explanatory and exploratory design as our research strategy. The method of the re-search is developed by the following three steps: (1) based on the previous literature, we elaborate category management background, its definition, explain category management process, analyze its demand side and the benefits it brings to retailers; (2) according to the above literature and theories, we create a working model which combines category management and its demand-driven side feature (i.e. customer focus, category management collaboration and strategic retailing positioning) in order to analyze the implementation of category management in Chinese super-market retailing; (3) we find a Chinese supermarket that is carrying out category management and conduct a case study based on it. With consideration of the working model, we explain how cate-gory management is implemented in the supermarket, find barrier and challenges during the im-plementation and make the corresponding suggestions to the current situation. The case study is based on interviews with major representatives from Lianhua supermarket and one of its suppli-ers in order to achieve insight into the essence of the problem. Findings and analysis - The implementation of category management in Lianhua supermarket includes “strong outlet” strategy aiming to deal with the supermarket development in a fierce competitive environment. Besides, Lianhua supermarket closely carries out the category management process and adapts the process according to its own positioning. Insufficient systems to support the implementation of category management, collaboration with suppliers is still on the fence, lack of internal managerial techniques and conflicts between category concentration and customers’ personalized shopping are the major barriers and challenges facing to Lianhua supermarket during its implementation of category management. Authors suggest Lianhua supermarket to invest IT resources, establish win-win strategic relationship, enhance top management commitment, improve internal collaboration and improve category performance measures. Research limitations – This research only restricts insights of category management on single case and specific geographical location. As for whether the research is also applied to other industry, the researched hasn’t been concerned and needs further research. The case study in the research is conducted only from retailer’s point of view. Findings obtained from the interviews are mostly from Lianhua supermarket side. The inadequate interview from supplier side is a clear limitation of the study, but it leaves an interest for future research.

Full textAbstract:
The objective of this research is to evaluate the potential of thermal energy storage in supermarkets with CO2 refrigeration systems. Suitable energy storage techniques are investigated and the seasonal storage technology of boreholes is chosen to be the focus of the study. The calculations are done for five supermarket refrigeration systems with different combinations of heating systems and borehole thermal energy storage control strategies. The two heating systems analyzed are the ground source heat pump and the heat recovery from the supermarket’s refrigeration system. The simulation results show that the introduction of thermal energy storage in the scenarios with heat pump can reduce the annual total energy by 6.3%. It is also shown that increasing the number of boreholes can decrease the life cycle cost of the system. Moreover, it is established that a supermarket system with heat recovery consumes 8.1% less energy than the one using heat pump and adding thermal energy storage on the heat recovery system further improves the energy consumption by 3.7% but may become costly.

Title: The Cold Chain Management in Supermarket-- Case Study on the Fresh Food Logistics in a supermarket Level: Final assignment for Master Degree in Logistics and Innovation Management Supervisor: Kaisu Sammalisto Date: June, 2011 Aim: The purpose of the paper is to research the cold chain management in supermarket by illustrating the case of a supermarket in Sweden. It aims to find out how the supermarket handles the fresh food cold chain by the perspective of cost and effectiveness. Method: The qualitative method was used in this paper, and the interview with the manager of the supermarket was conducted. The face to face interview provides the first hand information to the study. Neergaard et al (2007) state that qualitative approach is the best way to use to generalize the empirical investigations. To improve the validity, related literature was studied to get an initial idea about the research question. Result & Conclusions: The supermarket applies the simplicity strategy on the control of the fresh food cold chain. The unnecessary cost was cut down because of the simplicity strategy. Also, the local suppliers play an important role in the cost reduction. To improve the effectiveness, the supermarket uses the distribution centers and 3rd party logistics (3PL) to conduct integrated logistics.

PONTIFÍCIA UNIVERSIDADE CATÓLICA DO RIO DE JANEIROO varejo é um dos segmentos industriais que mais tem sofrido mudanças nos últimos anos, graças ao advento das tecnologias de informação e de telecomunicações que revolucionaram o mercado. Nos últimos 50 anos os supermercados brasileiros evoluíram de sua primeira loja até as lojas eletrônicas. Por um lado, estas aparecem para suas proprietárias como soluções baratas para expansão. Por outro, alguns segmentos de consumidores têm muita resistência a fazer suas compras pela Internet. Muitas pessoas, usuárias de computador e de Internet, preferem ir à loja em vez de fazer suas compras pela web. A proposta deste trabalho foi realizar uma pesquisa exploratória sobre as razões que levam consumidores a não utilizarem o meio eletrônico no momento de fazer suas compras de supermercado. O objetivo foi atingido em etapas. Inicialmente os atributos característicos das lojas de supermercado foram levantados através de pesquisa de observação. A etapa seguinte foi a realização de uma pesquisa qualitativa com grupos de discussão, com a finalidade de estudar a interação dos consumidores com os sites de supermercados através do método da análise do conteúdo. Por último, foi realizada uma pesquisa quantitativa com uma amostra de consumidores, a fim de levantar e testar as barreiras. A análise dos dados obtidos na pesquisa comprovou que existem barreiras para que consumidores com acesso a computador e Internet façam compras de supermercado on- line, as quais podem ser trabalhadas pelo varejista através de mudanças em seu mix de marketing.
Retailing is an industrial segment which has changed much in the last few years because of the development of information and telecommunication technologies that brought up a revolution in the world. In the last 50 years, Brazilian supermarkets have evolved from the first brick- and-mortar store to ecommerce. On the one hand, electronic supermarkets seem like a cheap solution for the expansion of their companies. On the other, certain consumer segments have great resistance in doing their shopping on the Internet. Many people, regular computer and Internet-users, would rather go to the physical store than do their shopping in the website. The goal of this paper is to perform an exploratory research on the reasons why consumers do not use electronic media when they do their supermarket shopping. To achieve this goal we went through certain steps. First, the attributes of brick-and-mortar supermarkets were described by observatory research. The following step was a qualitative research with focus groups, with the objective of studying the interaction of consumers with supermarket websites done through discourse analysis. The last step was a quantitative research with a sample of consumers, to raise and test the barriers. The analysis of the data obtained showed the existence of barriers to online supermarket shopping for consumers with access to computers and the Internet. These barriers can be overcome by the retailer through a change in the marketing mix.

Full textAbstract:
Improved sales forecasts for individual products in retail stores can have a positive effect both environmentally and economically. Historically these forecasts have been done through a combination of statistical measurements and experience. However, with the increased computational power available in modern computers, there has been an interest in applying machine learning for this problem. The aim of this thesis was to utilize two years of sales data, yearly calendar events, and weather data to investigate which machine learning method could forecast sales the best. The investigated methods were XGBoost, ARIMAX, LSTM, and Facebook Prophet. Overall the XGBoost and LSTM models performed the best and had a lower mean absolute value and symmetric mean percentage absolute error compared to the other models. However, Facebook Prophet performed the best in regards to root mean squared error and mean absolute error during the holiday season, indicating that Facebook Prophet was the best model for the holidays. The LSTM model could however quickly adapt during the holiday season improved the performance. Furthermore, the inclusion of weather did not improve the models significantly, and in some cases, the results were worsened. Thus, the results are inconclusive but indicate that the best model is dependent on the time period and goal of the forecast.Förbättrade försäljningsprognoser för individuella produkter inom detaljhandeln kan leda till både en miljömässig och ekonomisk förbättring. Historiskt sett har dessa utförts genom en kombination av statistiska metoder och erfarenhet. Med den ökade beräkningskraften hos dagens datorer har intresset för att applicera maskininlärning på dessa problem ökat. Målet med detta examensarbete är därför att undersöka vilken maskininlärningsmetod som kunde prognostisera försäljning bäst. De undersökta metoderna var XGBoost, ARIMAX, LSTM och Facebook Prophet. Generellt presterade XGBoost och LSTM modellerna bäst då dem hade ett lägre mean absolute value och symmetric mean percentage absolute error jämfört med de andra modellerna. Dock, gällande root mean squared error hade Facebook Prophet bättre resultat under högtider, vilket indikerade att Facebook Prophet var den bäst lämpade modellen för att förutspå försäljningen under högtider. Dock, kunde LSTM modellen snabbt anpassa sig och förbättrade estimeringarna. Inkluderingen av väderdata i modellerna resulterade inte i några markanta förbättringar och gav i vissa fall även försämringar. Övergripande, var resultaten tvetydiga men indikerar att den bästa modellen är beroende av prognosens tidsperiod och mål.

Full textAbstract:
Thesis (M.S.)--Massachusetts Institute of Technology, Dept. of Architecture, 1994.Includes bibliographical references (leaves 178-179).
This thesis examines the possibility of using a heat pipe installed in the air conditioning unit of a supermarket to increase the level of dehumidification of the inside air. This dehumidification is expected to reduce the energy consumption of the refrigeration system due to an improved efficiency of the heat transfer at the display case. This increase in efficiency will be due to reduced frost buildup on the refrigeration coils. Chapter two includes a physical and psychometric analysis of the heat pipe, proving that for any system where direct evaporation dehumidification is used, at any given time when dehumidification is being performed, the addition of a heat pipe will increase the amount of moisture being removed by the cooling coil. For this thesis, a heat pipe was installed in a supermarket in Worcester, Massachusetts. Over a period of the summer from the beginning of June to the end of October, various air temperatures and relative humidities, refrigeration line temperatures, pressures, and mass flows, and compressor power consumption were monitored for fifteen minute periods. The monitoring period included two months before the installation and three months after the installation to determine changes in the air system and refrigeration system due to the presence of the heat pipe. Chapters two through five describe the equipment, site and strategy used in the analysis. Chapter six describes the results of the monitoring, and Chapters seven and eight give the results of the air system and refrigeration system models. The systems were modelled using monitored data and engineering equations to predict humidity levels and power consumption based on ambient conditions. The analysis was unique in that a heat pipe application had never been previously studied in a Northeast location, since the mild summers made dehumidification less of an issue than in Southern states. This study was also considerably more in depth than previous studies (summarized in Chapter 2), for which savings estimates do not account for large potential errors. This study concluded that potential savings estimates (0-8% reduction in supply air humidity, -1 % reduction in refrigeration power) were within statistical error (9% for specific humidity, 4% for refrigeration power), and therefore inconclusive. Further studies with superior equipment and modelling strategies are needed to substantiate heat pipe dehumidification.

Tens of millions of predominantly low-income, minority Americans live in food deserts – areas with poor access to healthful, affordable food. Food deserts have been associated with higher rates of diet-related diseases such as high blood pressure and obesity. These diseases carry significant morbidity and mortality and account for hundreds of billions of dollars in healthcare spending and lost productivity per year in the U.S. Establishment of a supermarket is the most effective intervention to eliminate a food desert. However, food deserts have historically been neglected by the retail industry. Local governments are rarely involved in supermarket recruitment. Often, food deserts themselves must recruit supermarkets. This study sought to understand how leadership and community engagement in supermarket recruitment influence its efficacy. The objective was to enable food deserts to more effectively recruit supermarkets. A case study of Argentine, a low-income, minority neighborhood in Kansas City, KS that successfully recruited a supermarket in 2013, was conducted. The heart of the case study was a series of interviews with individuals who were heavily involved in the recruitment. This study found the results of community engagement – specifically a community food assessment – were leveraged to attract funding and financing for a supermarket development. In settings where recruitment of a supermarket is contingent upon obtainment of these dollars, community engagement may be critical. Engagement empowers people to play an active role in shaping the future of their communities. It is a vital component of the urban planning process and government in general. Additionally, in the context of a food desert, engagement of residents can help accomplish the lofty goal of recruiting a supermarket and improving the food landscape – and health – of the community.

Full textAbstract:
Food waste is considered to be a big problem worldwide. Different research projects have been done within this area in order to find ways that can help reduce this problem. This thesis addresses the problem of food waste in the supermarkets of Kosovo, by identifying the amounts of food waste in 3 supermarkets of this region. In addition, it explores the possibility of connection between supermarkets and charity organizations by using a developed prototype that corresponds to the field of web technologies. The prototype is implemented based on the feedback of supermarket workers. Interviews with open-ended questions were realized with supermarket workers and charity organization workers in order to identify the best medium that can be used to connect them. The prototype is realized using Wordpress, and evaluated first using the SUS questionnaire. Furthermore, it is also evaluated by performing usability test with supermarket and charity organization workers. The participants were asked to perform different tasks during the evaluation. The study shows that the use of the developed prototype reduces the amount of food waste in supermarkets. Furthermore, it successfully connects charity organizations with supermarkets. In addition, it provides a new way of controlling expiry dates of items resulting in reduction of waste inside supermarkets.

Full textAbstract:
This thesis addresses the evolution of supermarket architecture in the UK from the period following the Second World War up to the present day. It records the history of this phenomenon and explores the relationship between the developing architectural design styles of supermarket buildings and the social economic and political changes that have influenced their design. Focusing on the main objectives the research progressed through interview, observation and the analysis of archive material towards an inquiry into the nature, and particular significance, of these buildings and their place in the field of retail commerce. In order to examine in depth the concept of supermarket architectural design, four case studies are presented, both to illustrate the evolution of store design and to demonstrate the complex processes involved in the design and the completion of specific developments. These studies of individual stores together present a clear picture of the many variable elements that must be considered in the design and construction of a supermarket building. The discussion and conclusions drawn from the research material, in particular the four case studies, records and demonstrates the substance and meaning of these and other supermarket buildings and the influences, both mandatory and elective, that are important and significant in their design and the design of the sites they occupy. The review of relevant literature supports the conclusion that this research presents new knowledge in a field as yet unexplored by academic study.

Through interaction with customers, companies can acquire knowledge about- and satisfy the needs of customers. In retailing, the ranges of products are standardized and staffing numbers are scarce. How do companies in retailing deal with adaptation towards their customers given the small staffing numbers? The purpose of this study is to examine if and if so, how companies in the Swedish retailing industry are making adaptations towards their customers and also why these adaptations are being made. To answer this purpose, observations in the retailing industry are conducted and the results show that companies adapt to customers’ needs. However, this is not done through personalization. Finally, this study shows that companies in the retailing industry adapt to their customers mainly through mass-customization.
Genom interaktion med kunder kan företag skaffa sig kunskap om kundernas behov och tillgodose dessa. Inom dagligvaruhandeln är sortimenten standardiserade och personalstyrkan liten, något som torde missgynna interaktionen mellan parterna. Hur arbetar företag i dagligvaruhandeln med anpassningar till sina kunders behov när personaltätheten är förhållandevis låg? Syftet med studien är att undersöka om och i sådana fall hur ett företag inom den svenska dagligvaruhandeln anpassar sig till sina kunders behov, samt varför detta sker. För att besvara syftet görs observationer inom dagligvaruhandeln och resultaten visar att anpassning görs, dock ej personlig anpassning till enskilda kunders behov. Avslutningsvis visar studien att anpassning sker inom dagligvaruhandeln och att detta främst sker genom massanpassning.

Full textAbstract:
The purpose of this thesis is threefold: First, to explain how learning shapes consumer behaviour over a comestible (experience) good. Second, to examine the role of feedback information and information aggregation for consumer choices and market performance in markets for experience goods. Third, to understand how firms react to heterogeneous consumer choices in the supermarket industry when faced with institutional constraints. To shed light on how learning influences consumer choices over time in particular when new products or new characteristics are introduced, we employ in Chapter 2 a model of reinforcement learning over products as well as characteristics and apply it to yoghurt drink purchases from a large British consumer panel. We find that learning over both, products and characteristics, is important in explaining consumer choices over time. How consumer choices are influenced by the choice of others is analysed in Chapter 3 which introduces and studies a new model of aggregate information cascades. We find that if only one of two possible actions is observable say, how many others bought a particular product but not how many chose not to buy it only one type of cascade arises in equilibrium. Herding only takes place on the observable action. A different angle on how the provision of information bears on choices is taken in Chapter 4 on learning trust. Here we examine the effect of different forms of feedback information to consumers and sellers in a market with sequential exchange. Experimental evidence shows that both feedback information on sellers' history to consumers but also feedback information about sellers trading history to other sellers improves market efficiency. How firms optimally react to institutional constraints when consumer choice heterogeneity is important is developed in Chapter 5 in a model of supermarket entry into different store formats and applied to data from the UK. We are interested in estimating the cost of the institutional constraint of restrictive planning regulation. We find that the institutional set up matters but the impact of restrictive planning regulation on firm profits is small and increases barriers to entry for large supermarkets only.

Thesis (MBA)--Stellenbosch University, 2012.ENGLISH ABSTRACT: The book industry in South Africa is under severe pressure the last couple of years. The reason why the book industry in South Africa is under severe pressure is because of various reasons; one of the reasons is that the South African Government is spending less each year on education, specifically on school text books. As per the Willem Struik (2009) during the SABA conference in Durban, government has spend by more than 87% less on school text books. There is a further challenge for Publishers in order to generate more sales and that is that digitalization has a big impact on the turnover of publishers. The study is not doing an in-depth research on digitalisation and the impact thereof. The biggest impact that digitalisation has on the book industry and specific to publishers is that the gross profit is less for a digital book than a physical book. The main reason why the gross profit (GP) is less for a digital book is because all input costs remain the same for a digital and physical book, it is only the logistics where there is a cost saving (no more warehousing and physical distribution). The study analysis the potential additional revenue there is for publishers if they were to decide to supply to Supermarkets and not to the traditional book outlets only. The study as per Appendix A clearly indicates that there is definitely more revenue for the publishers to make if they were to supply books to supermarkets. The study also identifies that there are basically four role players in the business concept of supplying books to supermarkets and they are the publisher, retailer, logistics company and the end-consumer. The study indicates that in order for the business concept of supplying books to supermarkets to be successful all four role players have to believe in this concept and agree on the terms conditions from the various parties.

Full textAbstract:
The retail sector accounts for more than 3% of the total electricity consumption in the UK and approximately 1% of total UK CO2 emissions. The overarching aim of this project was to understand the energy consumption of the Tesco estate (the market leader), identify best practice, and find ways to identify opportunities for energy reduction. The literature review of this work covered the topic of energy consumption in the retail sector, and reviewed benchmarks for this type of buildings from the UK, Europe and the US. Related data analysis techniques used in the industry or presented in the literature were also reviewed. This revealed that there are many different analysis and forecasting techniques available, and that they fall into two different categories: techniques that require past energy consumption data in order to calculate the future consumption, such as statistical regression, and techniques that are able to estimate the energy consumption of buildings, based on the specific building's characteristics, such as thermal simulation models. These are usually used for new buildings, but they could also be used in benchmarking exercises, in order to achieve best practice guides. Gaps in the industry knowledge were identified, and it was suggested that better analytical tools would enable the industry to create more accurate energy budgets for the year ahead leading to better operating margins. Benchmarks for the organisation's buildings were calculated. Retail buildings in the Tesco estate were found to have electrical intensity values between 230 kWh/m2 and 2000 kWh/m2 per year. Still the average electrical intensity of these buildings in 2010-11 was found to be less than the calculated UK average of the 2006-07 period. The effect of weather on gas and electricity consumption was investigated, and was found to be significant (p < 0.001). There was an effect related to the day-of-the-week, but this was found to be more related to the sales volume on those days. Sales volume was a proxy that was used to represent the number of customers walking through the stores. The built date of the building was also considered to be an interesting factor, as the building regulations changed significantly throughout the years and the sponsor did not usually carry out any fabric work when refurbishing the stores. User behaviour was also identified as an important factor that needed to be investigated further, relating to both how the staff perceives and manages the energy consumption in their work environment, as well as how the customers use the refrigeration equipment. Following a statistical analysis, significant factors were determined and used to create multiple linear regression models for electricity and gas demands in hypermarkets. Significant factors included the sales floor area of the store, the stock composition, and a factor representing the thermo-physical characteristics of the envelope. Two of the key findings are the statistical significance of operational usage factors, represented by volume of sales, on annual electricity demand and the absence of any statistically significant operational or weather related factors on annual gas demand. The results suggest that by knowing as little as four characteristics of a food retail store (size of sales area, sales volume, product mix, year of construction) one can confidently calculate its annual electricity demands (R2=0.75, p < 0.001). Similarly by knowing the size of the sales area, product mix, ceiling height and number of floors, one can calculate the annual gas demands (R2=0.5, p < 0.001). Using the models created, along with the actual energy consumption of stores, stores that are not as energy efficient as expected can be isolated and investigated further in order to understand the reason for poor energy performance. Refrigeration data from 10 stores were investigated, including data such as the electricity consumption of the pack, outside air temperature, discharge and suction pressure, as well as percentage of refrigerant gas in the receiver. Data mining methods (regression and Fourier transforms) were employed to remove known operational patterns (e.g. defrost cycles) and seasonal variations. Events that have had an effect on the electricity consumption of the system were highlighted and faults that had been identified by the existing methodology were filtered out. The resulting dataset was then analysed further to understand the events that increase the electricity demand of the systems in order to create an automatic identification method. The cases analysed demonstrated that the method presented could form part of a more advanced automatic fault detection solution; potential faults were difficult to identify in the original electricity dataset. However, treating the data with the method designed as part of this work has made it simpler to identify potential faults, and isolate probable causes. It was also shown that by monitoring the suction pressure of the packs, alongside the compressor run-times, one could identify further opportunities for electricity consumption reduction.

This study provides an analysis of service quality perceptions across two distinct retail formats: supermarkets and hypermarkets. Service quality is addressed as a multidimensional concept, with four dimensions: physical aspects, personal interactions, reliability and policies. Such conceptualization enables the investigation of differences in the contribution of each dimension for overall service quality perception as well as for customer loyalty and recommendation intentions. The study was conducted in Portugal, and addressed a sample of hypermarket and supermarket customers. Data analysis addressed 248 complete questionnaires, and included: the characterization of service quality perceptions using descriptive statistics; the investigation of differences in customer perceptions across supermarkets and hypermarkets by means of hypothesis testing; and the estimation of regressions to analyze the impacts of the different service quality dimensions for customer satisfaction and loyalty. The results support the existence of differences in customer service quality evaluations across supermarket and hypermarket retail formats.
