Academic literature on the topic 'Supermarkets Location Victoria Case studies'

OBJECTIVE We examined whether relative availability of fast-food restaurants and supermarkets mediates the association between worse neighborhood socioeconomic conditions and risk of developing type 2 diabetes (T2D). RESEARCH DESIGN AND METHODS As part of the Diabetes Location, Environmental Attributes, and Disparities Network, three academic institutions used harmonized environmental data sources and analytic methods in three distinct study samples: 1) the Veterans Administration Diabetes Risk (VADR) cohort, a national administrative cohort of 4.1 million diabetes-free veterans developed using electronic health records (EHRs); 2) Reasons for Geographic and Racial Differences in Stroke (REGARDS), a longitudinal, epidemiologic cohort with Stroke Belt region oversampling (N = 11,208); and 3) Geisinger/Johns Hopkins University (G/JHU), an EHR-based, nested case-control study of 15,888 patients with new-onset T2D and of matched control participants in Pennsylvania. A census tract–level measure of neighborhood socioeconomic environment (NSEE) was developed as a community type-specific z-score sum. Baseline food-environment mediators included percentages of 1) fast-food restaurants and 2) food retail establishments that are supermarkets. Natural direct and indirect mediating effects were modeled; results were stratified across four community types: higher-density urban, lower-density urban, suburban/small town, and rural. RESULTS Across studies, worse NSEE was associated with higher T2D risk. In VADR, relative availability of fast-food restaurants and supermarkets was positively and negatively associated with T2D, respectively, whereas associations in REGARDS and G/JHU geographies were mixed. Mediation results suggested that little to none of the NSEE–diabetes associations were mediated through food-environment pathways. CONCLUSIONS Worse neighborhood socioeconomic conditions were associated with higher T2D risk, yet associations are likely not mediated through food-environment pathways.

Abstract. In this article, I work toward producing understandings of learning as liminal and as located in a liminal space. Framed as learning through the in-between, I engage with the concept of liminality as a way of unravelling the complexity of the practice of learning at the museum. Deploying data from video-based case studies of 40 school students' engagements with learning over the course of a visit to Museum Victoria, Australia, and utilising an analytic of assemblage, I map the spatial dynamics of learning in action. From analyses undertaken, it is argued that liminal spaces of learning open up in museum education and have a special salience. They have the potential to jump start the learner out of a comfortable state of mind and into a state of productive uncertainty. They also serve as a location for potential critique. More broadly, these analyses direct attention to the centrality of material practice and agency to liminality and liminal learning.

Purpose The purpose of this paper is to report four case studies in Australia that respond to the question: “How have schools with a relatively high degree of autonomy used their increased authority and responsibility to make decisions that have led in explicit cause-and-effect fashion to higher levels of student achievement”? Design/methodology/approach A conventional case study methodology was adopted, framed by a review of evidence in the international literature. The studies were conducted in the Australian Capital Territory, Queensland and Victoria. Senior leaders in systems of public education in these jurisdictions nominated schools which have had a relatively high degree of autonomy for at least two years; have achieved high levels of student achievement, or have shown noteworthy improvement; and are able to explain how the link between autonomy and achievement had been made. The four schools chosen from these nominations represented different types as far as level and location were concerned. Triangulation of sources was a feature of the studies. Findings The findings reveal that the schools were able to explain the links and that it was possible to map the cause-and-effect chain. Schools used their autonomy to select staff and allocate funds in their budgets, each being capacities that came with a higher level of autonomy. Leadership was important. Research limitations/implications The paper cautions against generalizing the findings. Originality/value There is international interest in the extent to which granting public schools a higher level of autonomy than has traditionally been the case in various national settings has had an impact on student achievement. These case studies go part of the way in describing what schools do when they successfully take up a higher level of authority and responsibility as one strategy in efforts to raise levels of achievement.

This paper reports findings from a comparative study which investigated public attitudes to recycled water in two Australian locations both in the state of Victoria: the capital city, Melbourne, and Bendigo, an urban regional centre. Two commercial buildings were used as case studies, one at each location. These buildings will soon be using recycled water for non-potable uses. The study was facilitated by an on-line survey of future occupants of both buildings to gauge their attitudes to recycled water use. Specifically the paper reports on happiness/willingness to use recycled water for various uses and attitudinal factors which were found to influence this. The circumstances for potable water availability and recycled water use differ in Melbourne and Bendigo, making this study a significant contribution to understanding public acceptance of recycled water use in these different contexts. No significant difference in happiness to use recycled water was found between locations. However, prior experience (use) of recycled water was found to be a significant and positive factor in facilitating happiness/willingness to use recycled water, particularly for closer to personal contact uses such as showering and drinking. Various attitudinal and demographic variables were found to influence happiness to use recycled water. Results indicate it is not just the locational context of water availability that influences happiness to use recycled water, but a person's experience and particular perceptions that will facilitate greater willingness to use recycled water.

This paper reports results from a study comparing perceived risk associated with various recycled water uses in two Australian locations, both in the state of Victoria: the capital city Melbourne, and Bendigo a regional urban centre. Both locations are experiencing ‘drought’, but Bendigo is experiencing this in a more acute manner. A case study is used in each location. Both case studies involve future use of recycled water in new commercial buildings. An on-line survey was used to measure attitudes to recycled water of the future occupants of both buildings. The study found perceived risk associated with 11 uses of recycled water increased as the use became increasingly personal. Interestingly, no difference in perceived risk associated with 11 uses of recycled water was found between locations. Prior experience (use) of recycled water was found to be a significant and positive factor in reducing risk perception. Various attitudinal variables were found to be significant influences on perceived risk. Results indicate that reducing perceived risk of recycled water use may increase satisfaction with its use.

Global warming effects have far reaching impacts of livelihoods of many rural communities including fishers. It is in record that fishing accounts for world’s 36 million fishers nearly 1.5 billion consumers who rely on fish for their dietary animal protein. Past studies have concentrated on fisher communities and climate variability in marine waters and oceans; mainly investigating the impact of climate variability on fish distribution and production. Limited focus has addressed the interaction between impacts of climate change on the fishing activities on inland and fresh waters such as in Lake Victoria and the fishers coping and adapting with changes and variability of climate. The discussions in this article focused on Lake Victoria shore location of Mbita where the livelihood of local community is largely fishing. The objectives were to: Determine the influence of gender on access and control of fisher resources for climate adaptation in Mbita sub-county; Document the current coping strategies and constraints to Climate variability/change in Mbita sub-county. The study used a constructivist epistemology and the mixed methods research design to help it achieve its findings. Yamane’s formula (1964) is used to get the sample size of 388 respondents out of a population of 13191. Primary data was collected through use of questionnaires, interview schedules for KII and FGDs. Secondary data collection was collected through document reviews of relevant past studies reports and working papers on (temperature/rainfall data) of Mbita for the last 30 years data to get the trend of these elements and to determine climate variability and change. The instruments were validated using experts’ content validity with the supervisors. Piloting was used to ascertain reliability of the instruments Analysis was accomplished using Statistical Packages for Social Sciences. Presentation was done in descriptive and inferential statistics. The study found that there was gender discrimination in access and control of resources which support adaptive activities that makes women more vulnerable to Climate Variability/Change hazards and disasters. The study further found that adaptation requires access and control of factors of production which were traditionally under the control of male fishers making women more vulnerable and susceptible to surviving through chamas and table banking activities. Statistically access to and control was significant to adaptation at p-value of 0.000. Under coping strategies the study found that adaptation required transformation of mind set that called for bigger investment which required the collaboration and consultation of entire Mbita community and county government to address environmental and conservative resource utility. The study concluded that lack of alternative livelihood opportunities/options is the major constraints to adaptation for people living in the Lake Victoria region escalated with limitation of skills outside fishing industry, limitation of other employable professional skills including lack of capital. The study recommends a transdiciplinary concientization of adaptive strategies which can translate into flexible and sustainable climate change adaptation and gender inclusive livelihood activities. Future research should explore participatory action research on environmental influences affecting CCA by comparing findings across other beaches and livelihoods to see if gendered resources have any role in their adaptation.

Abstract Due to correlations between purchasing patterns and diet disparities, differences in food shopping patterns and strategies across income levels and other socio-economic characteristics is a widely-studied research area. Most extant literature uses either primary or secondary data, which are often characterized by, respectively, limited geographical scope and considerable level of detail, or wide geographical reach but low detail. That literature also reveals contrasting results based on methods, data sources and geographic location. In this paper, we use three different datasets to characterize the differences in purchasing patterns across income levels, rural–urban status and other variables of food shoppers in the Northeastern USA and compare these trends with existing research. While many of the findings corroborate previous studies, new findings include less reliance on superstores overall, except for rural respondents, and a greater reliance on limited assortment supermarkets for SNAP and low-income households. Food purchasing differences are described by race and ethnicity, income and education, and children in the household. The analysis presented here includes a portion of the work performed by an interdisciplinary team of researchers engaged in the USDA National Institute of Food and Agriculture's Agriculture and Food Research Initiative project Enhancing Food Security in the Northeast (EFSNE). By using primary data from shoppers' intercept surveys, and secondary data from two large datasets, one of household food purchases and the other of food expenditures, we identify purchasing decisions holding at both the case-study (limited geography) and broader geographic (entire Northeast) levels, which both support previous findings and reveal the need for additional research in this area.

The primary objective of this study was to describe the food landscape of Flint, Michigan, and the surrounding townships. We investigated the relationship between the location of food outlets and the racial composition of census tracts. We collected data from multiple sources; however, Data Axle, a repository of information on the U.S. and Canadian businesses, was our primary data source. Data were collected and verified between September 2020 and December 2021. The final fact-checking was completed in June 2022. We used ArcGIS 10.8.1 and SPSS Version 28 to map and analyze the data. We conducted negative binomial regression analyses to identify the difference in the likelihood of finding food retailers in census tracts where the percentage of Black residents was low and those where the percentage of Blacks was high. The article examines 1,137 food retailers in the study area: 407 were in Flint, and the remainder in the surrounding townships. Restaurants—especially fast food and take-out establishments—dominated the food environment. In addition, small groceries and convenience stores proliferated in the grocery store category. The racial composition of the census tracts mattered. Census tracts in which more than 40% of the residents are Black have a mean of 7.6 food outlets. In comparison, census tracts in which 40% or less of the residents are Black have a mean of 11.3 food outlets; the difference is significant. Census tracts with a high percentage of Blacks also had significantly fewer restaurants. The results of this study show Flint’s food landscape to be more complex and robust than described in earlier studies. It underscores the point that researchers should not rely solely on documenting the presence of supermarkets or traditional grocery stores when addressing food insecurity and food access. In the case of Flint, such food outlets comprise only 2.2% of the food landscape. Focusing exclusively on these food retailers misses several important types of food venues that residents rely on to secure food. This siloed approach also ignores the resilience and ingenuity of residents to respond to limited access to traditional food retailers.

In today's society there is evidence of a culture of the 'empowered consumer' -- an image of the consumer as a citizen rather than a subordinate. In fact, human rights language is increasingly coming to the fore in the consumption debate. The consumer has been allocated rights by the United Nations whereby all human beings are born free and equal and have civil, political, economic and social rights (McGregor 44). However, as citizens we also have responsibilities of an environmental and social concern. Food retailing and equality of shopping provision is one such concern. Food is a basic right. According to the Universal Declaration of Human Rights everyone has a fundamental right to be free from hunger and have access to safe and nutritious food. Social exclusion refers to those in the population who are unable to participate in economic, political, social and cultural life. Social exclusion is different from, but related to, poverty since it further marginalises the most disadvantaged -- for example, those who cannot access a large supermarket. In keeping with the rights/responsibilities language, the consumer has a basic right to food and the retailer has the social responsibility to supply the needs of the consumer. It is in this respect that food is an ethical issue and has social justice implications. Inability to consume, or have access to, sufficient food of nutritional quality is a global concern. In North America the issue is one of 'food insecurity' or 'food poverty' due to inadequate finance to purchase sufficient food. In the United Kingdom the same problem arises within the context of access to food stores. This is identified as a 'food (shopping) desert', where due to restricted access social exclusion can arise. The term 'food deserts' was first used by the Low Income Project Team of the Nutrition Task Force in 1996 and was succinctly defined by Tessa Jowell (Government Health Minister) in 1997 when she stated that a food desert was an area "where people do not have easy access to healthy, fresh foods particularly if they are poor and have limited mobility". The term 'food desert' is an emotive one referring to a unique tool of social polarisation and exclusion (Lang 5). The issues compounding the problem include low income, locational policy of supermarkets with the acquisition of edge-of-town / out-of-town sites, consumer mobility, car ownership levels and food availability. This research study focuses on Northern Ireland -- a region of the UK on the periphery of Europe. The Province of Northern Ireland (Ulster) is a sparsely populated (122 people per km²), predominantly rural area with the highest unemployment and poverty statistics in the United Kingdom. Similarly, Northern Ireland has a proportionately high degree of non-car ownership (35%) which further complicates the equation since shopping is increasingly becoming a car-borne activity necessitating transportation to edge-of-town superstores. Those not able to avail themselves of large edge-of-town superstores are being socially excluded, since inner-city areas are becoming denuded of food stores. Those that do exist usually have a limited range of food items, usually non-perishable, or are specialist shops stocking high priced items. It is the aim of the study to identify the characteristics, extent and location of food deserts in both rural and urban areas of Northern Ireland. It is a particularly apt time to do so since Northern Ireland is experiencing a 'retail revolution' with the arrival of the major UK grocery multiples and subsequent situational policies to locate off-centre. Similarly, there are plans to curtail out-of-town developments which has been viewed by some smaller retailers as "too little, too late". With the above in mind, it is a timely study for Northern Ireland. Multiple research tools of both a qualitative and a quantitative nature have been employed including consumer focus groups, shopping diaries, comparative shopping exercises, consumer questionnaires and retail interviews. This will enable sufficient validation of results. The focus groups provide qualitative depth (Colquhoun 39) and serve to highlight the issues of shopping inequality from the point of view of different consumer groups which could be identified as potentially vulnerable in the food poverty stakes; the elderly, the disabled, the unemployed or low income families, lone-parent families and females in general; to whom falls the responsibility for provisioning the household, organising the kitchen and doing the household's cooking (Murcott 11). Basically, food is gendered -- women are mainly in charge (Vaines 13). The respondents in this study demonstrate exactly that point since 77% of the sample were female and reported that they were responsible for household shopping. This point is particularly prevalent with regard to access to cars. In fact over 50% of women in 1991-1993 either lived in households without a car or were non-drivers in a household with a car. Similarly, although there is a rising proportion of women who work they still do most of the shopping and spend twice as much time as men provisioning the household (Piachaud & Webb 18). Ultimately, anything that affects the purchaser also affects the purchasing experience -- in this case physical access to the foodstore. Comparative shopping exercises illustrate the availability and price indices of food and reiterate the price differences between the smaller independents, the local corner shops and the supermarkets. Initial research using the British Ministry of Agriculture, Fisheries and Food's "Low Cost, Healthy Diet" (Leather 75) provides evidence of a cost differential of £1.41, or a 26% cost penalty by shopping at a corner store rather than a superstore. Availability among corner shops similarly compared unfavourably with the supermarkets, with the smallest stores offering minimal fresh fruit and vegetables and regularly offering no 'economy' branded equivalent to an established manufacturer's brand. This supports previous research which found that in areas where small shops do exist they offer only a limited overpriced range of processed foods (Elliott 5), and it is generally accepted that those who can shop at supermarkets can generally benefit from lower prices and more choice (Piachaud & Webb 32). The benefits of supermarkets are not therefore available to all. Shopping diaries further illustrate this point with the dichotomy existing where the lower-income consumer shops more frequently and locally than does her higher-income counterpart and it is these same consumers who patronise the smaller, often more expensive corner shop. Many consumers like the convenience of large supermarkets where they have access to a vast range of items and do not mind paying premium prices on some items for this convenience. Supermarkets do not offer low prices on all items, but do stock economy lines as well as premium priced items. The consumer questionnaire provides some quantitative analysis and statistical weight to the data and was analysed using the χ-square test on SPSS for Windows Version 8. With the χ-square test the important detail is the significance level (reported as a p-value). A p-value of less than 0.05 indicates that the two groups are significantly different at a confidence level of 95% -- in other words, it can be concluded that the author is 95% certain that the result is statistically significant and free from error. Four areas of the Province were sampled -- two rural and two urban. The sample was 77% female and the median age group fell between 45 to 54 years. The social class status was skewed towards the lower socio-economic classes and only 12% fell into social classes A or B. The mean household income was £151 to £200 per week. The survey was interviewer-assisted and pointed to some interesting correlations between levels of satisfaction with store location and distance travelled, product choice and the decision to continue shopping in the town centre. Thirty percent of the sample stated that they shop at off-centre complexes and 70% of the sampled households shop in the town centre or closer to home. This sample also provides evidence that shopping is largely a car-borne activity with 58% of the sample using the family car. Journey distance is significantly influenced by degree of satisfaction with locality: p<0.01 and is supported with the evidence that 64% of the respondents stated that they shop less than fifteen minutes from home. Similar relationships exist between reported satisfaction with locality and differing degrees of satisfaction for product choice: p<0.01. A significant bias similarly exists between those who continue to shop in the town centre after the advent of the UK multiples into Northern Ireland in 1996 and those who do not: p<0.05 with a bias towards those continuing to shop in the town centre reporting high satisfaction levels. Ultimately, perceived adequacy of shopping provision influences satisfaction with store locality: p<0.05. Although the majority of respondents' weekly shopping is conducted at a multiple there is still an identified need for the local corner shops and independents since approximately 29% of respondents buy essentials like bread, milk and other basic grocery provision there. In fact, 98% of those surveyed reported that every town centre should have a food store, and 82% noticed a reduction in the number of food stores locally in recent years. In a concluding open question in the survey attitudes towards off-centre supermarkets were gauged. Responses ranged from positive in nature ("better parking facilities") to indifferent ("I never bother with them") to negative ("they [out-of-town supermarkets] only suit people with cars" and "they hurt the small shopkeeper"). From a retail management point of view, the multiple stores perceive (or want the consumer to believe) that they have a "social responsibility" but suggest that it should be a coalition between retailers and councillors to rejuvenate the town centres and it is not their sole responsibility. The corner shops argue their business position has survived but allude to the fact that the migration to out-of-town sites by the supermarkets has "created a void in the town centre". The issue is complex. While it is true that the multiples have brought shoppers a number of benefits -- price, choice and quality -- they have also both directly (siting shops outside town centres and in high income areas) and indirectly (undermining the economies of small, local outlets) increased costs on disadvantaged consumers in terms of time, physical effort and transport. This has led to a degree of social exclusion amongst certain consumer groups, although this was not quantitatively expressed as significant via the medium of the questionnaire in this preliminary study. It should be remembered that food and mealtimes are imbued with social and cultural meaning (Lang 27) and that "food is a vehicle for social control" (7). In fact food desertification has been likened to the "food equivalent of disconnecting the water supply" (27) and initiatives should be considered to alleviate food poverty and rejuvenate town centres throughout the Province. A multidisciplinary approach is necessary with input from retailers, councillors, health promotion personnel and education bodies to bring about a policy to eradicate this form of social exclusion and disadvantage.

IntroductionSupermarkets are functionally challenging environments for people with vision impairments. A supermarket is likely to house an average of 45,000 products in a median floor-space of 4,529 square meters and many visually impaired people are unable to shop without assistance, which greatly impedes personal independence (Nicholson et al.). The task of selecting goods in a supermarket is an “activity that is expressive of agency, identity and creativity” (Sutherland) from which many vision-impaired persons are excluded. In response to this, a number of proof of concept (demonstrating feasibility) and prototype assistive technologies are being developed which aim to use smart phones as potential sensorial aides for vision impaired persons. In this paper, I discuss two such prototypic technologies, Shop Talk and BlindShopping. I engage with this issue’s list theme by suggesting that, on the one hand, list making is a uniquely human activity that demonstrates our need for order, reliance on memory, reveals our idiosyncrasies, and provides insights into our private lives (Keaggy 12). On the other hand, lists feature in the creation of spatial inventories that represent physical environments (Perec 3-4, 9-10). The use of lists in the architecture of assistive technologies for shopping illuminates the interaction between these two modalities of list use where items contained in a list are not only textual but also cartographic elements that link the material and immaterial in space and time (Haber 63). I argue that despite the emancipatory potential of assistive shopping technologies, their efficacy in practical situations is highly dependent on the extent to which they can integrate a number of lists to produce representations of space that are meaningful for vision impaired users. I suggest that the extent to which these prototypes may translate to becoming commercially viable, widely adopted technologies is heavily reliant upon commercial and institutional infrastructures, data sources, and regulation. Thus, their design, manufacture and adoption-potential are shaped by the extent to which certain data inventories are accessible and made interoperable. To overcome such constraints, it is important to better understand the “spatial syntax” associated with the shopping task for a vision impaired person; that is, the connected ordering of real and virtual spatial elements that result in a supermarket as a knowable space within which an assisted “spatial practice” of shopping can occur (Kellerman 148, Lefebvre 16).In what follows, I use the concept of lists to discuss the production of supermarket-space in relation to the enabling and disabling potentials of assistive technologies. First, I discuss mobile digital technologies relative to disability and impairment and describe how the shopping task produces a disabling spatial practice. Second, I present a case study showing how assistive technologies function in aiding vision impaired users in completing the task of supermarket shopping. Third, I discuss various factors that may inhibit the liberating potential of technology assisted shopping by vision-impaired people. Addressing Shopping as a Disabling Spatial Practice Consider how a shopping list might inform one’s experience of supermarket space. The way shopping lists are written demonstrate the variability in the logic that governs list writing. As Bill Keaggy demonstrates in his found shopping list Web project and subsequent book, Milk, Eggs, Vodka, a shopping list may be written on a variety of materials, be arranged in a number of orientations, and the writer may use differing textual attributes, such as size or underlining to show emphasis. The writer may use longhand, abbreviate, write neatly, scribble, and use an array of alternate spelling and naming conventions. For example, items may be listed based on knowledge of the location of products, they may be arranged on a list as a result of an inventory of a pantry or fridge, or they may be copied in the order they appear in a recipe. Whilst shopping, some may follow strictly the order of their list, crossing back and forth between aisles. Some may work through their list item-by-item, perhaps forward scanning to achieve greater economies of time and space. As a person shops, their memory may be stimulated by visual cues reminding them of products they need that may not be included on their list. For the vision impaired, this task is near impossible to complete without the assistance of a relative, friend, agency volunteer, or store employee. Such forms of assistance are often unsatisfactory, as delays may be caused due to the unavailability of an assistant, or the assistant having limited literacy, knowledge, or patience to adequately meet the shopper’s needs. Home delivery services, though readily available, impede personal independence (Nicholson et al.). Katie Ellis and Mike Kent argue that “an impairment becomes a disability due to the impact of prevailing ableist social structures” (3). It can be said, then, that supermarkets function as a disability producing space for the vision impaired shopper. For the vision impaired, a supermarket is a “hegemonic modern visual infrastructure” where, for example, merchandisers may reposition items regularly to induce customers to explore areas of the shop that they wouldn’t usually, a move which adds to the difficulty faced by those customers with impaired vision who work on the assumption that items remain as they usually are (Schillmeier 161).In addressing this issue, much emphasis has been placed on the potential of mobile communications technologies in affording vision impaired users greater mobility and flexibility (Jolley 27). However, as Gerard Goggin argues, the adoption of mobile communication technologies has not necessarily “gone hand in hand with new personal and collective possibilities” given the limited access to standard features, even if the device is text-to-speech enabled (98). Issues with Digital Rights Management (DRM) limit the way a device accesses and reproduces information, and confusion over whether audio rights are needed to convert text-to-speech, impede the accessibility of mobile communications technologies for vision impaired users (Ellis and Kent 136). Accessibility and functionality issues like these arise out of the needs, desires, and expectations of the visually impaired as a user group being considered as an afterthought as opposed to a significant factor in the early phases of design and prototyping (Goggin 89). Thus, the development of assistive technologies for the vision impaired has been left to third parties who must adopt their solutions to fit within certain technical parameters. It is valuable to consider what is involved in the task of shopping in order to appreciate the considerations that must be made in the design of shopping intended assistive technologies. Shopping generally consists of five sub-tasks: travelling to the store; finding items in-store; paying for and bagging items at the register; exiting the store and getting home; and, the often overlooked task of putting items away once at home. In this process supermarkets exhibit a “trichotomous spatial ontology” consisting of locomotor space that a shopper moves around the store, haptic space in the immediate vicinity of the shopper, and search space where individual products are located (Nicholson et al.). In completing these tasks, a shopper will constantly be moving through and switching between all three of these spaces. In the next section I examine how assistive technologies function in producing supermarkets as both enabling and disabling spaces for the vision impaired. Assistive Technologies for Vision Impaired ShoppersJason Farman (43) and Adriana de Douza e Silva both argue that in many ways spaces have always acted as information interfaces where data of all types can reside. Global Positioning System (GPS), Radio Frequency Identification (RFID), and Quick Response (QR) codes all allow for practically every spatial encounter to be an encounter with information. Site-specific and location-aware technologies address the desire for meaningful representations of space for use in everyday situations by the vision impaired. Further, the possibility of an “always-on” connection to spatial information via a mobile phone with WiFi or 3G connections transforms spatial experience by “enfolding remote [and latent] contexts inside the present context” (de Souza e Silva). A range of GPS navigation systems adapted for vision-impaired users are currently on the market. Typically, these systems convert GPS information into text-to-speech instructions and are either standalone devices, such as the Trekker Breeze, or they use the compass, accelerometer, and 3G or WiFi functions found on most smart phones, such as Loadstone. Whilst both these products are adequate in guiding a vision-impaired user from their home to a supermarket, there are significant differences in their interfaces and data architectures. Trekker Breeze is a standalone hardware device that produces talking menus, maps, and GPS information. While its navigation functionality relies on a worldwide radio-navigation system that uses a constellation of 24 satellites to triangulate one’s position (May and LaPierre 263-64), its map and text-to-speech functionality relies on data on a DVD provided with the unit. Loadstone is an open source software system for Nokia devices that has been developed within the vision-impaired community. Loadstone is built on GNU General Public License (GPL) software and is developed from private and user based funding; this overcomes the issue of Trekker Breeze’s reliance on trading policies and pricing models of the few global vendors of satellite navigation data. Both products have significant shortcomings if viewed in the broader context of the five sub-tasks involved in shopping described above. Trekker Breeze and Loadstone require that additional devices be connected to it. In the case of Trekker Breeze it is a tactile keypad, and with Loadstone it is an aftermarket screen reader. To function optimally, Trekker Breeze requires that routes be pre-recorded and, according to a review conducted by the American Foundation for the Blind, it requires a 30-minute warm up time to properly orient itself. Both Trekker Breeze and Loadstone allow users to create and share Points of Interest (POI) databases showing the location of various places along a given route. Non-standard or duplicated user generated content in POI databases may, however, have a negative effect on usability (Ellis and Kent 2). Furthermore, GPS-based navigation systems are accurate to approximately ten metres, which means that users must rely on their own mobility skills when they are required to change direction or stop for traffic. This issue with GPS accuracy is more pronounced when a vision-impaired user is approaching a supermarket where they are likely to encounter environmental hazards with greater frequency and both pedestrian and vehicular traffic in greater density. Here the relations between space defined and spaces poorly defined or undefined by the GPS device interact to produce the supermarket surrounds as a disabling space (Galloway). Prototype Systems for Supermarket Navigation and Product SelectionIn the discussion to follow, I look at two prototype systems using QR codes and RFID that are designed to be used in-store by vision-impaired shoppers. Shop Talk is a proof of concept system developed by researchers at Utah State University that uses synthetic verbal route directions to assist vision impaired shoppers with supermarket navigation, product search, and selection (Nicholson et al.). Its hardware consists of a portable computational unit, a numeric keypad, a wireless barcode scanner and base station, headphones for the user to receive the synthetic speech instructions, a USB hub to connect all the components, and a backpack to carry them (with the exception of the barcode scanner) which has been slightly modified with a plastic stabiliser to assist in correct positioning. Shop Talk represents the supermarket environment using two data structures. The first is comprised of two elements: a topological map of locomotor space that allows for directional labels of “left,” “right,” and “forward,” to be added to the supermarket floor plan; and, for navigation of haptic space, the supermarket inventory management system, which is used to create verbal descriptions of product information. The second data structure is a Barcode Connectivity Matrix (BCM), which associates each shelf barcode with several pieces of information such as aisle, aisle side, section, shelf, position, Universal Product Code (UPC) barcode, product description, and price. Nicholson et al. suggest that one of their “most immediate objectives for future work is to migrate the system to a more conventional mobile platform” such as a smart phone (see Mobile Shopping). The Personalisable Interactions with Resources on AMI-Enabled Mobile Dynamic Environments (PRIAmIDE) research group at the University of Deusto is also approaching Ambient Assisted Living (AAL) by exploring the smart phone’s sensing, communication, computing, and storage potential. As part of their work, the prototype system, BlindShopping, was developed to address the issue of assisted shopping using entirely off-the-shelf technology with minimal environmental adjustments to navigate the store and search, browse and select products (López-de-Ipiña et al. 34). Blind Shopping’s architecture is based on three components. Firstly, a navigation system provides the user with synthetic verbal instructions to users via headphones connected to the smart phone device being used in order to guide them around the store. This requires a RFID reader to be attached to the tip of the user’s white cane and road-marking-like RFID tag lines to be distributed throughout the aisles. A smartphone application processes the RFID data that is received by the smart phone via Bluetooth generating the verbal navigation commands as a result. Products are recognised by pointing a QR code reader enabled smart phone at an embossed code located on a shelf. The system is managed by a Rich Internet Application (RIA) interface, which operates by Web browser, and is used to register the RFID tags situated in the aisles and the QR codes located on shelves (López-de-Ipiña and 37-38). A typical use-scenario for Blind Shopping involves a user activating the system by tracing an “L” on the screen or issuing the “Location” voice command, which activates the supermarket navigation system which then asks the user to either touch an RFID floor marking with their cane or scan a QR code on a nearby shelf to orient the system. The application then asks the user to dictate the product or category of product that they wish to locate. The smart phone maintains a continuous Bluetooth connection with the RFID reader to keep track of user location at all times. By drawing a “P” or issuing the “Product” voice command, a user can switch the device into product recognition mode where the smart phone camera is pointed at an embossed QR code on a shelf to retrieve information about a product such as manufacturer, name, weight, and price, via synthetic speech (López-de-Ipiña et al. 38-39). Despite both systems aiming to operate with as little environmental adjustment as possible, as well as minimise the extent to which a supermarket would need to allocate infrastructural, administrative, and human resources to implementing assistive technologies for vision impaired shoppers, there will undoubtedly be significant establishment and maintenance costs associated with the adoption of production versions of systems resembling either prototype described in this paper. As both systems rely on data obtained from a server by invoking Web services, supermarkets would need to provide in-store WiFi. Further, both systems’ dependence on store inventory data would mean that commercial versions of either of these systems are likely to be supermarket specific or exclusive given that there will be policies in place that forbid access to inventory systems, which contain pricing information to third parties. Secondly, an assumption in the design of both prototypes is that the shopping task ends with the user arriving at home; this overlooks the important task of being able to recognise products in order to put them away or to use at a later time.The BCM and QR product recognition components of both respective prototypic systems associates information to products in order to assist users in the product search and selection sub-tasks. However, information such as use-by dates, discount offers, country of manufacture, country of manufacturer’s origin, nutritional information, and the labelling of products as Halal, Kosher, containing alcohol, nuts, gluten, lactose, phenylalanine, and so on, create further challenges in how different data sources are managed within the devices’ software architecture. The reliance of both systems on existing smartphone technology is also problematic. Changes in the production and uptake of mobile communication devices, and the software that they operate on, occurs rapidly. Once the fit-out of a retail space with the necessary instrumentation in order to accommodate a particular system has occurred, this system is unlikely to be able to cater to the requirement for frequent upgrades, as built environments are less flexible in the upgrading of their technological infrastructure (Kellerman 148). This sets up a scenario where the supermarket may persist as a disabling space due to a gap between the functional capacities of applications designed for mobile communication devices and the environments in which they are to be used. Lists and Disabling Spatial PracticeThe development and provision of access to assistive technologies and the data they rely upon is a commercial issue (Ellis and Kent 7). The use of assistive technologies in supermarket-spaces that rely on the inter-functional coordination of multiple inventories may have the unintended effect of excluding people with disabilities from access to legitimate content (Ellis and Kent 7). With de Certeau, we can ask of supermarket-space “What spatial practices correspond, in the area where discipline is manipulated, to these apparatuses that produce a disciplinary space?" (96).In designing assistive technologies, such as those discussed in this paper, developers must strive to achieve integration across multiple data inventories. Software architectures must be optimised to overcome issues relating to intellectual property, cross platform access, standardisation, fidelity, potential duplication, and mass-storage. This need for “cross sectioning,” however, “merely adds to the muddle” (Lefebvre 8). This is a predicament that only intensifies as space and objects in space become increasingly “representable” (Galloway), and as the impetus for the project of spatial politics for the vision impaired moves beyond representation to centre on access and meaning-making.ConclusionSupermarkets act as sites of hegemony, resistance, difference, and transformation, where the vision impaired and their allies resist the “repressive socialization of impaired bodies” through their own social movements relating to environmental accessibility and the technology assisted spatial practice of shopping (Gleeson 129). It is undeniable that the prototype technologies described in this paper, and those like it, indeed do have a great deal of emancipatory potential. However, it should be understood that these devices produce representations of supermarket-space as a simulation within a framework that attempts to mimic the real, and these representations are pre-determined by the industrial, technological, and regulatory forces that govern their production (Lefebvre 8). Thus, the potential of assistive technologies is dependent upon a range of constraints relating to data accessibility, and the interaction of various kinds of lists across the geographic area that surrounds the supermarket, locomotor, haptic, and search spaces of the supermarket, the home-space, and the internal spaces of a shopper’s imaginary. These interactions are important in contributing to the reproduction of disability in supermarkets through the use of assistive shopping technologies. The ways by which people make and read shopping lists complicate the relations between supermarket-space as location data and product inventories versus that which is intuited and experienced by a shopper (Sutherland). Not only should we be creating inventories of supermarket locomotor, haptic, and search spaces, the attention of developers working in this area of assistive technologies should look beyond the challenges of spatial representation and move towards a focus on issues of interoperability and expanded access of spatial inventory databases and data within and beyond supermarket-space.ReferencesDe Certeau, Michel.
