    Even though whole grain foods have various health benefits, consumers have been found not to eat enough of them. Nudging interventions are built on the premise that food purchases and consumption are strongly influenced by the environment in which decisions are made. Little research has been conducted to examine the influence of a small and inexpensive nudging intervention on bread choices in a real-life supermarket context. An in-store experiment was conducted in two six-week periods in two supermarkets to investigate the effects of accessibility on consumers’ purchase of healthier whole grain and other types of bread. In the high accessibility condition, healthier bread was placed in a more convenient location for the shopper on the left side of the shelves where it was encountered first. In the low accessibility condition, it was placed on the right side. There were consistent significant differences in sales between supermarkets, types of bread, day of the week, but not between low and high accessibility. Additional research is needed to better understand the effects of convenience and accessibility on bread choices. PMID:27010704

    连锁超市已成为中国大城市内部零售商业的主要业态.针对目前研究中对城市内部尺度连锁超市空间布局问题关注不足,本文以南京市苏果超市为例,从空间格局演化、集聚分布状况、不同类型超市的区位选择等方面进行分析.研究方法包括点模式分析、空间密度分析和空间自相关分析等.结果发现:南京市苏果超市的空间总体分布呈中心到外围递减的倒“U”型集聚特征;不同类型苏果超市的分布特征不同,华润卖场的空间分布相对分散,社区店、便利店的分布相对集聚;空间分布热点呈蔓延扩散与等级扩散混合模式.运用Binary Logistic二分逻辑回归对影响超市区位选择的因素进行计量分析,结果表明经济发展情况、消费者规模、交通通达性、居民购买力、城乡差别、公司战略等多种因素,通过综合作用机制,共同推动了南京市苏果超市的空间分布格局.%Chain supermarkets have been main formats of retail business within large cities of China. Current studies pay little attention to spatial distribution of chain supermarkets on the scale of internal city. Taking Suguo supermarkets in Nanjing as an example, this paper focuses on spatial pattern evolution, agglomeration, and location decisions of different types of supermarkets using research methods including point pattern analysis, space density analysis and spatial autocorrelation analysis. The results show that Suguo supermarkets present an inverted-U-shaped pattern with the mode of extending to the surrounding area around the core of the downtown area. Different types of supermarkets present different distribution characteristics. Resource stores are relatively disperse while community and convenience stores are relatively concentrated. The spatial distribution of hot spots shows a mixed mode of spreading diffusion within the main city and hierarchical diffusion from the main city to the suburbs

    Full Text Available FIABA is a cultural route for all, its aim is to promote a Global Accessibility and a Universal Usability through the removal of architectural, cultural, psychological and sensory barriers. FIABA is carrying out a real change and a cultural renewal in the name of equal opportunities. Respect for the environment in which we live is also a duty towards the younger generations to whom we must deliver a world in which free movement and the normal use of spaces are goals already achieved. There are millions of citizens who, because of their physical conditions are prisoners in their homes because there isn’t any elevator or any elevator maintenance. FIABA project aims at implementing “a Space for all” or “a landscape for all” following the path of the ONU Convention on the Rights of People with disabilities with an emphasis on architectural, cultural, and psychological barriers, the last ones in particular, create barriers to equal opportunities and they are often carriers of discrimination. The principle of accessibility is invoked in Article 9 of the Convention which confirms the principle that people have a right to live independently and participate fully in all spheres of life and thus States are required to take all necessary measures to ensure accessibility to physical environment, transport, information and communications, including systems and technologies of information and communication and other facilities and services open to the public, both in urban and rural areas.

    Full Text Available Abstract Background Previous studies have provided mixed evidence with regards to associations between food store access and dietary outcomes. This study examines the most commonly applied measures of locational access to assess whether associations between supermarket access and fruit and vegetable consumption are affected by the choice of access measure and scale. Method Supermarket location data from Glasgow, UK (n = 119, and fruit and vegetable intake data from the ‘Health and Well-Being’ Survey (n = 1041 were used to compare various measures of locational access. These exposure variables included proximity estimates (with different points-of-origin used to vary levels of aggregation and density measures using three approaches (Euclidean and road network buffers and Kernel density estimation at distances ranging from 0.4 km to 5 km. Further analysis was conducted to assess the impact of using smaller buffer sizes for individuals who did not own a car. Associations between these multiple access measures and fruit and vegetable consumption were estimated using linear regression models. Results Levels of spatial aggregation did not impact on the proximity estimates. Counts of supermarkets within Euclidean buffers were associated with fruit and vegetable consumption at 1 km, 2 km and 3 km, and for our road network buffers at 2 km, 3 km, and 4 km. Kernel density estimates provided the strongest associations and were significant at a distance of 2 km, 3 km, 4 km and 5 km. Presence of a supermarket within 0.4 km of road network distance from where people lived was positively associated with fruit consumption amongst those without a car (coef. 0.657; s.e. 0.247; p0.008. Conclusions The associations between locational access to supermarkets and individual-level dietary behaviour are sensitive to the method by which the food environment variable is captured. Care needs to be taken to ensure robust and conceptually

    The historic cities of Brazil, despite its colonial structure, don't fail to go through transformations that affect contemporary cities, which is the main source of problems, leading to new approaches to urban issues such as mobility and accessibility. The uncontrolled growth of tourism in the historic cities can be considered as a big problem, because at the same time, they have committed to the conservation of its built heritage and demand control of the activities that occur in their areas without harm. Then, a permanent dialogue between conservatives and planners could be accomplished by joining the various sectoral policies. The study of urban mobility in historical sites was in fact the focus of this work because of their peculiarities, such as its specific characteristics of urban structure, morphology and occupation. In fact, the development of tourism in historic centers generates specific demands, such as adaptation to new uses of the houses, intensive movement of people and vehicles, illegal parking, among others. Beyond threatening the city preservation, does not provide mobility and accessibility to tourists, because these cities were not designed for the tourism conditions and needs of contemporary life. Characteristic features of Brazilian baroque cities, such as topography , the narrow streets, narrow or nonexistent sidewalks, steep turns and ramps strong, are not suitable for heavy vehicles, traffic and pedestrian circulation. Thus, studies concerning conservation urban integrated are aimed at an approach to interaction between historic preservation of the environment with the dynamic socio-economic of the local.

    Information from the nutrition facts labels of toddler foods marketed in low- and high-income New York City zip codes were analyzed for sodium content, the proportion of sugar-derived calories, and presence of sugar and/or high-fructose corn syrup as an added sweetener in the list of ingredients. Among the 272 toddler foods analyzed, more than a quarter were high in sodium, over one-third derived at least 20% their calories from sugar, and more than 41% of the foods had sugar and/or high-fructose corn syrup listed among the first five ingredients. The proportion of foods with such nutritional characteristics did not significantly differ between the low- and high-income neighborhood supermarkets. Median sodium content was highest among "side dishes" and "meals." The proportion of calories derived from sugar was found to be highest among "snacks and yogurt blends" in both low- and high-income neighborhoods and "breakfast foods and cereals" in low-income neighborhoods. When compared to high-income neighborhoods, more than three times the proportion of total calories in "breakfast foods and cereals" sold in low-income neighborhoods were derived from sugar. Since taste preferences established during childhood can have long-lasting influence on dietary habits, it is imperative to limit the promotion of toddler foods that are high in sodium and sugar as well as educate parents to make nutritionally sound decisions at the point of purchase.

    Placing full-service supermarkets in food deserts--areas with limited access to healthy food--has been promoted as a way to reduce inequalities in access to healthy food, improve diet, and reduce the risk of obesity. However, previous studies provide scant evidence of such impacts. We surveyed households in two Pittsburgh, Pennsylvania, neighborhoods in 2011 and 2014, one of which received a new supermarket in 2013. Comparing trends in the two neighborhoods, we obtained evidence of multiple positive impacts from new supermarket placement. In the new supermarket neighborhood we found net positive changes in overall dietary quality; average daily intakes of kilocalories and added sugars; and percentage of kilocalories from solid fats, added sugars, and alcohol. However, the only positive outcome in the recipient neighborhood specifically associated with regular use of the new supermarket was improved perceived access to healthy food. We did not observe differential improvement between the neighborhoods in fruit and vegetable intake, whole grain consumption, or body mass index. Incentivizing supermarkets to locate in food deserts is appropriate. However, efforts should proceed with caution, until the mechanisms by which the stores affect diet and their ability to influence weight status are better understood. PMID:26526243

    One of the most significant developments in the last couple of decades in the retail industry has been the emergence of large supermarkets (hypermarkets). The purpose of this paper is to investigate the effect on prices of the entry of a large supermarket into a given location. We use a panel with data from fifteen cities in Chile for the period 1998:I – 2004:IV. The dependent variable is the price of a bundle of 52 food products in each city relative to Santiago. We find that the entry of a ...

  14. Supermarkets and Planning Regulation

    OpenAIRE

    Griffith, Rachel; Harmgart, Heike

    2008-01-01

    We are interested in evaluating the impact of restrictive planning regulation on entry into the UK grocery retail industry. We estimate a model similar to Bresnahan and Reiss (1991) where we allow for multiple store formats. We find that more restrictive planning regulation reduces the number of large format supermarkets in equilibrium. However, the impact is overstated if variation in demographic characteristics across markets is not also controlled for. Our estimates suggest that restrictiv...

  15. Supermarket Pricing Strategies

    Most supermarket firms choose to position themselves by offering either everyday low prices (EDLP) across several items or offering temporary price reductions (promotions) on a limited range of items. While this choice has been addressed from a theoretical perspective in both the marketing and economic literature, relatively little is known about how these decisions are made in practice, especially within a competitive environment. This paper exploits a unique store level data set consisting ...

  16. The Supermarket Game

    CERN Document Server

    Xu, Jiaming

    2012-01-01

    A supermarket game is considered with $N$ FCFS queues with unit exponential service rate and global Poisson arrival rate $N \\lambda$. Upon arrival each customer chooses a number of queues to be sampled uniformly at random and joins the least loaded sampled queue. Customers are assumed to have cost for both waiting and sampling, and they want to minimize their own expected total cost. We study the supermarket game in a mean field model that corresponds to the limit as $N$ converges to infinity in the sense that (i) for a fixed symmetric customer strategy, the joint equilibrium distribution of any fixed number of queues converges as $N \\to \\infty$ to a product distribution determined by the mean field model and (ii) a Nash equilibrium for the mean field model is an $\\epsilon$-Nash equilibrium for the finite $N$ model with $N$ sufficiently large. It is shown that there always exists a Nash equilibrium for $\\lambda <1$ and the Nash equilibrium is unique with homogeneous waiting cost for $\\lambda^2 \\le 1/2$. Fu...

  6. The Making of a Sustainable Wireless City? Mapping Public Wi-Fi Access in Shanghai

    Directory of Open Access Journals (Sweden)

    Mingfeng Wang

    2016-01-01

    Full Text Available In the context of the global information economy, ready access to the Internet is critical to a city’s competitiveness, which has prompted a number of cities to launch plans to establish wireless networks. Most literature on the development of wireless cities focuses on cities in Western countries, and few have discussed how Chinese cities have adopted wireless technologies in their urban infrastructure development efforts. This paper examines recent development and spatial distribution of public Wi-Fi access in Shanghai, a leading business hub in China. We mapped Wi-Fi hotspots through the government sponsored “i-Shanghai” project and China Mobile Communications Corporation (CMCC. We find that while telecommunication providers have been proactively deploying WLAN (wireless local area network,a proxy of public Wi-Fi or wireless access hotspots in Shanghai, neither government sponsored WLAN hotspots nor facilities established by CMCC could cover the old traditional neighborhoods in the central city and sub-districts in remote rural areas. We also address the development of a more sustainable wireless city in Shanghai with a particular focus on digital divide and social equity issues.

    2013-01-01

    Full Text Available Access to essential medicines is fundamental to medication adherence, continuity of care and hence population health outcomes and overall quality of life. Disparities in the availability and the cost of these medications in New York City, especially for low income neighborhoods, would compound the underlying health disparities in these neighborhoods. This study examined the physical and financial accessibility to 8 of the 150 Most Frequently Prescribed Drugs in New York, 2 each for Asthma, Diabetes, Hypertension, and Hyperlipidemia, 4 conditions that are among the top 10 most costly conditions in the United States. The study did not find any significant differences in mean drug prices between the high, medium, and low income neighborhoods in the City. However, the significantly different income levels and uninsured rates across neighborhood income strata in the City (p<0.001 for both, coupled with the high disease burden and other underlying disparities in low income neighborhoods, would point to potential affordability challenges for needed medications in these neighborhoods. On the other hand, significant differences in mean prices between the 5 City boroughs were found for 3 of the study drugs: Advair®, p=0.009; Amlodipine 10mg, p<0.001; and Lisinopril 10mg, p=0.046. No such significant differences were observed for the mean prices of the other 5 study drugs-Proventil HFA,® Metformin HCL 500mg, Glipizide ER 5mg, Simvastatin 20mg, and Atorvastatin 10mg. The study findings did not also suggest that drug prices are dictated by the number of pharmacies in a neighborhood.Further studies would be needed to better understand the complexities associated with the accessibility of essential medicines in New York City. These studies could include qualitative ones which would examine the perceptions and experiences of City residents with respect to the accessibility of prescribed medications as the basis for targeted interventions directed at promoting

  8. Solar access of residential rooftops in four California cities

    Energy Technology Data Exchange (ETDEWEB)

    Levinson, Ronnen; Akbari, Hashem; Pomerantz, Melvin

    2010-05-14

    Shadows cast by trees and buildings can limit the solar access of rooftop solar-energy systems, including photovoltaic panels and thermal collectors. This study characterizes residential rooftop shading in Sacramento, San Jose, Los Angeles and San Diego, CA. Our analysis can be used to better estimate power production and/or thermal collection by rooftop solar-energy equipment. It can also be considered when designing programs to plant shade trees. High-resolution orthophotos and LiDAR (Light Detection And Ranging) measurements of surface height were used to create a digital elevation model of all trees and buildings in a well-treed 2.5-4 km{sup 2} residential neighborhood. On-hour shading of roofing planes (the flat elements of roofs) was computed geometrically from the digital elevation model. Values in future years were determined by repeating these calculations after simulating tree growth. Parcel boundaries were used to determine the extent to which roofing planes were shaded by trees and buildings in neighboring parcels. For the subset of S+SW+W-facing planes on which solar equipment is commonly installed for maximum solar access, absolute light loss in spring, summer and fall peaked about two to four hours after sunrise and about two to four hours before sunset. The fraction of annual insolation lost to shading increased from 0.07-0.08 in the year of surface-height measurement to 0.11-0.14 after 30 years of tree growth. Only about 10% of this loss results from shading by trees and buildings in neighboring parcels.

    Alternative methods to provide space conditioning in supermarkets were studied. Four basic air-conditioning systems were selected for evaluation in a store in Miami, Florida: (1) conventional vapor compression systems, (2) vapor compression air-conditioning systems designed for supermarket loads, (3) hybrid desiccant air-conditioning systems, and (4) cool storage systems. Computer models were created and annual simulations of performance were made. The impacts on energy use and cost of circulation flow rate, store humidity set point, heat pipe heat exchangers, and climate on energy use and cost were determined. Dual path electric systems and desiccant systems were found to consume the least electrical energy. Savings of the desiccant system are partially offset by natural gas needed to reactivate the desiccant. Single path systems with reduced circulation air flow consumed significantly less electricity than the conventional system. Lower humidity shifts the air-conditioning load from the refrigerated cases to the HVAC system and reduces the electrical use for all but the conventional system. Heat pipe heat exchangers provide little benefit. Flat and time-of-use electric rate schedules were used to estimate operating savings and to determine the cost effectiveness of the alternative approaches.

  17. Lighting designs for supermarket applications

    Energy Technology Data Exchange (ETDEWEB)

    Warren, C.S.

    1996-05-01

    Designers of lighting systems for supermarket applications face a number of challenges when the goals are to present merchandise in an attractive environment, but to do so in an energy-efficient manner. The Defense Commissary Agency (DeCA) operates several hundred stores worldwide, and more than 150 within the United States. DeCA is a federal agency that was organized in 1991 to operate commissaries that had previously been operated by the various armed services. As a federal agency, DeCA is also under a federal executive order to reduce its total energy consumption per square foot of floor space by 20 percent by the year 2005, compared to energy use in the year 1990. On the average, lighting consumes more than 20 percent of a store`s total energy use. Lighting retrofit projects offer opportunities to save significant energy costs with reasonable cost payback. The variety of ages and architectural styles of the commissaries offer opportunities for analysis and design of a wide diversity of projects. These projects range from simple replacements of lamps and ballasts to luminaire replacements and complete redesign of systems, including circuits. The requirements of merchandising products (illumination) also affect system designs. Several types of lighting retrofit projects are discussed. Problems that were encountered and solutions that were developed are shown. Because commissaries are supermarkets, lighting system designs are applicable to commercial establishments.

    The selling of weapons-related nuclear knowledge by Russian scientists for economic gain constitutes a threat to US national security. Some estimate that the number of Russian scientists seeking permanent employment abroad constitute five to ten percent of all researchers who have left the field of science. And, there is concern that those who have left are ''the better minds.'' Moreover, the issue of brain drain concerns not only those who move abroad permanently, but those who still reside in Russia and travel abroad to sell their knowledge. Of particular concern to the US is the potential sale of WMD knowledge by some. To ''mitigate the risk that economic difficulties...might create the temptation for individuals or institutes to sell expertise to countries of proliferation concern and terrorist organizations,'' the Department of Energy launched a Nuclear Cities Initiative (NCI) in 1998 with the goal of creating commercial jobs and economic diversification in the ten closed cities that form the core of Russia's nuclear weapons complex to accommodate the loss of employment in the nuclear weapons industry. However, unless Russia opens access to the areas of its closed cities that are, or could become, involved in commercial activities-while of course carefully controlling access to the sensitive areas of the institutes and laboratories-economic development will be stymied.

    Full Text Available Background: Rapid rural-urban migration of people to cities is a reality around the globe that has increased city slum dwellers. Sodom and Gomorrah is a city slum located in the heart of Accra, Ghana. Like other slums, it lacks basic amenities necessary for dwellers’ quality of life. This study describes residents’ access to health and factors associated with the use of healthcarefacilities.Methods: Questionnaires were administered in systematically selected shacks across the entire slum. Data on demographic characteristics, existent health facilities and number of users, health-insured residents and knowledge of common diseases were collected.Results: Majority of the residents were from the northern parts of Ghana, relative to the south and a few of them come from other parts of West Africa. Seventy-one percent of residents had never visited a health facility in the last 5 years. When necessary, they access health care from drug stores (61.1% or hospitals (33.1%. Residents’ age, educational status, income, health knowledge and membership of National Health Insurance Scheme were significantly (p < 0.05 associated with the use of healthcare facilities. Younger residents and those without National Health Insurance Scheme membership, formal education, no knowledge of common illnesses and regular income were significantly less likely to use a healthcare facility. For most residents, neither distance (73.2% nor transportation to health facilities was a problem (74.1%.Conclusion: Conditions of profound environmental hazards, overcrowding, poor-quality housing and lack of health care in Sodom and Gomorrah pose grave threats to the health of the inhabitants. Multisectoral interventions and resource mobilisation championed by the Ministry of Local Government and Rural Development are needed to alter the trend.Keywords: Slum dwellers, health, access, Sodom and Gomorra, Ghana

  6. Supermarket revolution in Asia and emerging development strategies to include small farmers.

    Science.gov (United States)

    Reardon, Thomas; Timmer, C Peter; Minten, Bart

    2012-07-31

    A "supermarket revolution" has occurred in developing countries in the past 2 decades. We focus on three specific issues that reflect the impact of this revolution, particularly in Asia: continuity in transformation, innovation in transformation, and unique development strategies. First, the record shows that the rapid growth observed in the early 2000s in China, Indonesia, Malaysia, and Thailand has continued, and the "newcomers"--India and Vietnam--have grown even faster. Although foreign direct investment has been important, the roles of domestic conglomerates and even state investment have been significant and unique. Second, Asia's supermarket revolution has exhibited unique pathways of retail diffusion and procurement system change. There has been "precocious" penetration of rural towns by rural supermarkets and rural business hubs, emergence of penetration of fresh produce retail that took much longer to initiate in other regions, and emergence of Asian retail developing-country multinational chains. In procurement, a symbiosis between modern retail and the emerging and consolidating modern food processing and logistics sectors has arisen. Third, several approaches are being tried to link small farmers to supermarkets. Some are unique to Asia, for example assembling into a "hub" or "platform" or "park" the various companies and services that link farmers to modern markets. Other approaches relatively new to Asia are found elsewhere, especially in Latin America, including "bringing modern markets to farmers" by establishing collection centers and multipronged collection cum service provision arrangements, and forming market cooperatives and farmer companies to help small farmers access supermarkets.

    Full Text Available Objective: To understand the characteristics of access to the General System of Social Security in health (SGSS, from the perspective of doctors, nurses, administrators and users. Methodology: based on the grounded theory we present a study in six cities in Colombia: Barranquilla, Bucaramanga, Bogota, Leticia, Medellín and Pasto, for which interviews were conducted in-depth with health professionals involved in service delivery and focus groups with service users. Results: The findings indicate that insurance has become an end in itself, and being affiliated to SGSSS does not guarantee effective access to services. The dominance of the market, the financial profitability of insurers, imposed cost-containment mechanisms over the right to health. There are limitations from the rules, benefit plans that create geographical, economic and cultural barriers from the various actors involved in the chain of decisions. Additionally, display individual and institutional ethical shortcomings, clientelism and corruption in the management of resources, coupled with poverty and geographical dispersion of communities, mean that further limiting access to health services.

    Ligthart, F.A.T.M. [ECN Energy in the Built Environment, Petten (Netherlands)

    2008-11-15

    The City of Amsterdam's Environmental and Building Department commissioned the Energy research Centre of the Netherlands (ECN) to calculate the time needed to recoup the cost of closing the existing refrigerator and freezer display cabinets used in supermarkets. We were asked to give particular consideration to the following aspects: (1) The cabinet's energy consumption; (2) The energy price; and (3) The cost of closing the cabinet. The payback period has been calculated by dividing the investment required to close the cabinet by the amount saved on energy each year, less any additional costs incurred as a result of the scheme. For existing upright refrigerator cabinets, that period works out at 2.9 years with a margin error of {+-}0.9 years. In the case of chest freezers, it is approximately 2.4 years, with a maximum of 2.5 and a minimum of 1.3 years. For chest refrigerators, the payback period is 9.4 years. If units are closed overnight only, the time needed to payback the cost of that measure ranges between 1.8 and 4.1 years. Moreover, research shows that closing refrigerator and freezer display units will not reduce turnover. In addition, it will significantly improve the ambient climate in supermarkets.

    The objective of this project was to determine the potential energy savings associated with implementing demand defrost strategies to defrost supermarket refrigerated display case evaporators, as compared to the widely accepted current practice of controlling display case defrost cycles with a preset timer. The defrost heater energy use of several representative display case types was evaluated. In addition, demand defrost strategies for refrigerated display cases as well as those used in residential refrigerator/freezers were evaluated. Furthermore, it is anticipated that future work will include identifying a preferred defrost strategy, with input from Retail Energy Alliance members. Based on this strategy, a demand defrost system will be designed which is suitable for supermarket refrigerated display cases. Limited field testing of the preferred defrost strategy will be performed in a supermarket environment.

  14. Field Testing and Modeling of Supermarket Refrigeration Systems as a Demand Response Resource

    Energy Technology Data Exchange (ETDEWEB)

    2016-08-26

    Supermarkets offer a substantial demand response (DR) resource because of their high energy intensity and use patterns; however, refrigeration as the largest load has been challenging to access. Previous work has analyzed supermarket DR using heating, ventilating, and air conditioning; lighting; and anti-sweat heaters. This project evaluated and quantified the DR potential inherent in supermarket refrigeration systems in the Bonneville Power Administration service territory. DR events were carried out and results measured in an operational 45,590-ft2 supermarket located in Hillsboro, Oregon. Key results from the project include the rate of temperature increase in freezer reach-in cases and walk-ins when refrigeration is suspended, the load shed amount for DR tests, and the development of calibrated models to quantify available DR resources. Simulations showed that demand savings of 15 to 20 kilowatts (kW) are available for 1.5 hours for a typical store without precooling and for about 2.5 hours with precooling using only the low-temperature, non-ice cream cases. This represents an aggregated potential of 20 megawatts within BPA's service territory. Inability to shed loads for medium-temperature (MT) products because of the tighter temperature requirements is a significant barrier to realizing larger DR for supermarkets. Store owners are reluctant to allow MT case set point changes, and laboratory tests of MT case DR strategies are needed so that owners become comfortable testing, and implementing, MT case DR. The next-largest barrier is the lack of proper controls in most supermarket displays over ancillary equipment, such as anti-sweat heaters, lights, and fans.

  15. Relationship between mode choice and the location of supermarkets – empirical analysis in Austria

    Full Text Available Main goal of the study work is to gain data about shopping and mobility behaviour at small local supermarkets with sales floor space less than 1.000 m2. Four location types have been defined and discussed; rural  peripheral location, rural  central location, urban – central location and urban – peripheral location. 200 shoppers each location were interviewed at the exit of the supermarket, which means a total of 800 interviews were carried out during all day times and working days of the supermarket. As expected, the mode choice is strongly dependent on the location of the supermarket. In car oriented settlements, which can be found at rural peripheral locations, nearly all shoppers accessed the supermarket with their cars. If weighting the expenditure per visit with the frequency of visits, the average expenditure per month and mode can be derived. The average purchase per month between the modes is more or less balanced. A difference in behaviour lies in the fact that cyclists and pedestrians go shopping more frequently but are spending less per visit. Additionally, the results of this study are indicating the existence of a potential mode shift, especially if there is better land use planning for supermarket locations. Furthermore, considering the given situation and a given threshold of less than 5 kilograms of weight of the goods purchased, more than fifty percent of all shoppers could use non motorised modes with insignificant loss of travel quality. Combined with short travel distances to the next shop (the average distance is 4.9 km, a change to alternative means of transport would be relatively easy for a significant number of shoppers.

    2012-01-01

    The proliferation of sensing devices create plethora of data-streams, which in turn can be harnessed to carry out sophisticated analytics to support various real-time applications and services as well as long-term planning, e.g., in the context of intelligent cities or smart homes to name a few prominent ones. A mature cloud infrastructure brings such a vision closer to reality than ever before. However, we believe that the ability for data-owners to flexibly and easily to control the granularity at which they share their data with other entities is very important - in making data owners feel comfortable to share to start with, and also to leverage on such fine-grained control to realize different business models or logics. In this paper, we explore some basic operations to flexibly control the access on a data stream and propose a framework eXACML+ that extends OASIS's XACML model to achieve the same. We develop a prototype using the commercial StreamBase engine to demonstrate a seamless combination of strea...

    2015-11-01

    Full Text Available The sustainability strategy in urban spaces arises from reflecting on how to achieve a more habitable city and is materialized in a series of sustainable transformations aimed at humanizing different environments so that they can be used and enjoyed by everyone without exception and regardless of their ability. Modern communication technologies allow new opportunities to analyze efficiency in the use of urban spaces from several points of view: adequacy of facilities, usability, and social integration capabilities. The research presented in this paper proposes a method to perform an analysis of movement accessibility in sustainable cities based on radio frequency technologies and the ubiquitous computing possibilities of the new Internet of Things paradigm. The proposal can be deployed in both indoor and outdoor environments to check specific locations of a city. Finally, a case study in a controlled context has been simulated to validate the proposal as a pre-deployment step in urban environments.

  20. What does SNAP benefit usage tell us about food access in low-income neighborhoods?

    Science.gov (United States)

    Shannon, Jerry

    2014-04-01

    Current GIS based research on food access has focused primarily on the proximity of food sources to places of residence in low-income communities, with relatively little attention given to actual practices of food procurement. This project addresses this issue by using dasymetric mapping techniques to develop fine scale estimates of benefit usage for the Supplemental Nutrition Assistance Program (SNAP) in the Twin Cities of Minneapolis and St. Paul, Minnesota, drawing from existing zip code level data on benefit distribution and redemptions. Based on this data, this research shows that while supermarkets receive almost all SNAP benefits in suburban areas, these stores have a smaller share of all SNAP redemptions in low-income core neighborhoods. In these latter areas, both convenience stores and mid-sized grocers (e.g., discount grocers, food cooperatives, ethnic markets) play a much larger role in residents' food shopping, even when supermarkets are also present. In addition, these core neighborhoods have a net "outflow" of SNAP dollars, meaning that residents of these areas receive more in benefits than is spent at neighborhood food retailers. This finding confirms existing research showing that low-income residents often travel outside their neighborhoods to get food, regardless of the presence or absence of supermarkets. Rather than simply increasing the number of large food outlets in low-access areas, this research suggests that efforts to improve food access and community health must take into account the geographically complex ways residents interact with the food system.

    Full Text Available The prevalence of overweight and obesity in the US is a serious public health problem. Supermarkets in the US are responding to the obesity epidemic by providing the unique asset of food, pharmacy and registered dietitians in one location to help grocery shoppers manage diseases and improve nutrition. Recent studies report that supermarket point-of-purchase interventions focusing on improving healthy food purchasing behaviours are feasible and potentially efficacious. We describe our experiences and lessons learned while developing a university-supermarket partnership and pilot testing a supermarket POP intervention (Healthstyles-Eat Smart© prior to its dissemination throughout the region. Barriers to and facilitators of developing university-supermarket partnerships and strategies to increase the feasibility of supermarket POP research are discussed. We conclude that strong university-supermarket partnerships are essential to conducting supermarket intervention research and are worth the time and effort it takes to build them.

  9. Associations of supermarket characteristics with weight status and body fat: a multilevel analysis of individuals within supermarkets (RECORD study.

    Directory of Open Access Journals (Sweden)

    Basile Chaix

    Full Text Available PURPOSE: Previous research on the influence of the food environment on weight status has often used impersonal measures of the food environment defined for residential neighborhoods, which ignore whether people actually use the food outlets near their residence. To assess whether supermarkets are relevant contexts for interventions, the present study explored between-residential neighborhood and between-supermarket variations in body mass index (BMI and waist circumference (WC, and investigated associations between brands and characteristics of supermarkets and BMI or WC, after adjustment for individual and residential neighborhood characteristics. METHODS: Participants in the RECORD Cohort Study (Paris Region, France, 2007-2008 were surveyed on the supermarket (brand and exact location where they conducted their food shopping. Overall, 7 131 participants shopped in 1 097 different supermarkets. Cross-classified multilevel linear models were estimated for BMI and WC. RESULTS: Just 11.4% of participants shopped for food primarily within their residential neighborhood. After accounting for participants' residential neighborhood, people shopping in the same supermarket had a more comparable BMI and WC than participants shopping in different supermarkets. After adjustment for individual and residential neighborhood characteristics, participants shopping in specific supermarket brands, in hard discount supermarkets (especially if they had a low education, and in supermarkets whose catchment area comprised low educated residents had a higher BMI/WC. CONCLUSION: A public health strategy to reduce excess weight may be to intervene on specific supermarkets to change food purchasing behavior, as supermarkets are where dietary preferences are materialized into definite purchased foods.

  10. Spatial accessibility to vaccination sites in a campaign against rabies in São Paulo city, Brazil.

    Polo, Gina; Acosta, Carlos Mera; Dias, Ricardo Augusto

    2013-08-01

    It is estimated that the city of São Paulo has over 2.5 million dogs and 560 thousand cats. These populations are irregularly distributed throughout the territory, making it difficult to appropriately allocate health services focused on these species. To reasonably allocate vaccination sites, it is necessary to identify social groups and their access to the referred service. Rabies in dogs and cats has been an important zoonotic health issue in São Paulo and the key component of rabies control is vaccination. The present study aims to introduce an approach to quantify the potential spatial accessibility to the vaccination sites of the 2009 campaign against rabies in the city of São Paulo and solve the overestimation associated with the classic methodology that applies buffer zones around vaccination sites based on Euclidean (straight-line) distance. To achieve this, a Gaussian-based two-step floating catchment area method with a travel-friction coefficient was adapted in a geographic information system environment, using distances along a street network based on Dijkstra's algorithm (short path method). The choice of the distance calculation method affected the results in terms of the population covered. In general, areas with low accessibility for both dogs and cats were observed, especially in densely populated areas. The eastern zone of the city had higher accessibility values compared with peripheral and central zones. The Gaussian-based two-step floating catchment method with a travel-friction coefficient was used to assess the overestimation of the straight-line distance method, which is the most widely used method for coverage analysis. We conclude that this approach has the potential to improve the efficiency of resource use when planning rabies control programs in large urban environments such as São Paulo. The findings emphasize the need for surveillance and intervention in isolated areas. PMID:23602338

  11. Newton in the Big Apple: Issues of equity in physics access and enrollment in New York City public high schools

    Science.gov (United States)

    Kelly, Angela Marian

    High school physics is a gateway course for post-secondary study in science, medicine, and engineering, as well as an essential component in the formation of students' scientific literacy. However, physics is widely considered appropriate only for an academic elite. The existence of policies that restrict science opportunities for secondary students results in diminished outcomes in terms of scientific proficiency. Although the national trend in physics enrollment has shown an increase in recent years, the rate of participation is much lower for students in urban schools. This study examines the availability of physics in New York City, and whether access is related to organizational and school-level variables. The statistical distribution of physics students throughout the city is compiled and analyzed. High schools that successfully offer physics are compared with those that do not. Other factors are explored to determine their relationship to physics access, such as the presence of science magnet schools, the availability of Advanced Placement Physics and Non-Regents Physics, the science curricular sequence, and teacher certification. The results show that physics is not widely available to students in New York City, with 55% of high schools simply not offering the subject. Only 27% of schools with fewer than 600 students offer physics. The science magnet schools enroll a significant proportion of physics students when compared with larger, economically depressed neighborhood schools. The causes of these disparities are complex, and the implications serious for those students who do not have equal access to physics. The implications of these findings are important. By highlighting descriptive variables, as well as statistical evidence of systemic discrimination and inequities, urban districts may formulate effective models for the promotion of physics study. School policies and structures need to target better rates of physics participation among all students

    Full Text Available Abstract Background Inequity of accessibility to and utilization of reproductive health (RH services among youths is a global concern, especially in resource-limited areas. The level of inequity also varies by cultural and socio-economic contexts. To tailor RH services to the needs of youths, relevant solutions are required. This study aimed to assess baseline information on access to and utilization of RH services and unmet needs among youths living in resource-limited, suburban communities of Mandalay City, Myanmar. Methods A community-based, cross-sectional study was conducted in all resource-limited, suburban communities of Mandalay City, Myanmar. A total of 444 randomly selected youths aged between 15 and 24 years were interviewed for three main outcomes, namely accessibility to and utilization of RH services and youth's unmet needs for these services. Factors associated with these outcomes were determined using multivariate logistic regression. Results Although geographical accessibility was high (79.3%, financial accessibility was low (19.1% resulting in a low overall accessibility (34.5% to RH services. Two-thirds of youths used some kind of RH services at least once in the past. Levels of unmet needs for sexual RH information, family planning, maternal care and HIV testing were 62.6%, 31.9%, 38.7% and 56.2%, respectively. Youths living in the south or south-western suburbs, having a deceased parent, never being married or never exposed to mass media were less likely to access RH services. Being a young adult, current student, working as a waste recycler, having ever experienced a sexual relationship, ever being married, ever exposed to mass media, having a high knowledge of RH services and providers or a high level of accessibility to RH services significantly increased the likelihood of utilization of those services. In addition to youths’ socio-demographic characteristics, exposure to mass media, norm of peer exposure and knowledge

    2009-06-01

    Full Text Available Abstract Background Proximity to parks and physical activity sites has been linked to an increase in active behaviors, and positive impacts on health outcomes such as lower rates of cardiovascular disease, diabetes, and obesity. Since populations with a low socio-economic status as well as racial and ethnic minorities tend to experience worse health outcomes in the USA, access to parks and physical activity sites may be an environmental justice issue. Geographic Information systems were used to conduct quantitative and qualitative analyses of park accessibility in New York City, which included kernel density estimation, ordinary least squares (global regression, geographically weighted (local regression, and longitudinal case studies, consisting of field work and archival research. Accessibility was measured by both density of park acreage and density of physical activity sites. Independent variables included percent non-Hispanic black, percent Hispanic, percent below poverty, percent of adults without high school diploma, percent with limited English-speaking ability, and population density. Results The ordinary least squares linear regression found weak relationships in both the park acreage density and the physical activity site density models (Ra2 = .11 and .23, respectively; AIC = 7162 and 3529, respectively. Geographically weighted regression, however, suggested spatial non-stationarity in both models, indicating disparities in accessibility that vary over space with respect to magnitude and directionality of the relationships (AIC = 2014 and -1241, respectively. The qualitative analysis supported the findings of the local regression, confirming that although there is a geographically inequitable distribution of park space and physical activity sites, it is not globally predicted by race, ethnicity, or socio-economic status. Conclusion The combination of quantitative and qualitative analyses demonstrated the complexity of the issues around

  5. Super-Exponential Solution for a Retrial Supermarket Model

    CERN Document Server

    Li, Quan-Lin; Wang, Yang

    2011-01-01

    In this paper, we provide a new and effective approach for studying super-exponential solution of a retrial supermarket model with Poisson arrivals, exponential service times and exponential retrial times and with two different probing-server numbers. We describe the retrial supermarket model as a system of differential equations by means of density-dependent jump Markov processes, and obtain an iterative algorithm for computing the fixed point of the system of differential equations. Based on the fixed point, we analyze the expected sojourn time that a tagged arriving customer spends in this system, and use numerical examples to indicate different influence of the two probing-server numbers on system performance including the fixed point and the expected sojourn time. Furthermore, we analyze exponential convergence of the current location of the retrial supermarket model to the fixed point, and apply the Kurtz Theorem to study density-dependent jump Markov process given in the retrial supermarket model, whic...

    2009-10-01

    Full Text Available The retailer style includes department store, hypermarket, supermarkets, convenience stores, cooperative union, traditional markets and shopping mall in Taiwan. This thesis wants from the supermarkets to make the further discussion. The study of customer loyalty, particularly customer loyalty research on Chinese retail supermarket--Wumart Group has some significance. With the increasingly furious competition, the profit margins constantly decline and it needs to find new profit growth points through customer loyalty resources mastered by the retail enterprise. At the same time, major retail enterprises in China have taken different management strategies to avoid brutal price wars. The customer loyalty provides support for differentiated strategies, such support is not only reflected in materials of the purchase information provided by the customer information, but also reflected in the learn-type relationship between the retail business and customer loyalty. Therefore, the research on customer loyalty is a required course for modern retail enterprises, especially for supermarkets.Research will focus mainly on surveys to get data and the interviews. The second objective of the research is to identify the determinants of service loyalty in Wumart Group. Apart from assessing the extent of customer churn in the supermarket, primary research is carried out to test the proposed model of customer loyalty. This study seeks not only to examine the relationship between customer satisfaction and customer loyalty, but also to include the analysis on the areas of customer loyalty and switching behaviours influenced by loyalty club cards.

    Full Text Available As shopping becomes a shared experience and joint process with friends or family members nowadays, the most important problems arise with variety of products and the product information available in the supermarkets. This study proposes a system that uses Intelligent Apriori algorithm to support consumers in getting the required items from various supermarkets. Also this work intelligently suggests the best movement and reducing unwanted movement of the customer and quickly finds out the next operation which includes the next supermarket which is visited by the customer for the next item he/she purchases. This approach can further be extended to the world of mobile communication where the next movement of the mobile user can be predicted and used intelligently to arrange necessary requirements at the destination before he actually reaches. The feasibility of this approach is tested under simple conditions and the results are presented in this study.

    Matsa, David A

    2011-01-01

    This article analyzes the effect of competition on a supermarket firm's incentive to provide product quality. In the supermarket industry, product availability is an important measure of quality. Using U.S. Consumer Price Index microdata to track inventory shortfalls, I find that stores facing more intense competition have fewer shortfalls. Competition from Walmart—the most significant shock to industry market structure in half a century—decreased shortfalls among large chains by about a third. The risk that customers will switch stores appears to provide competitors with a strong incentive to invest in product quality. PMID:22148133

  3. A Mixed-Method Assessment of a New Supermarket in a Food Desert: Contributions to Everyday Life and Health.

    2016-06-01

    Initiatives to build supermarkets in low-income areas with relatively poor access to large food retailers ("food deserts") have been implemented at all levels of government, although evaluative studies have not found these projects to improve diet or weight status for shoppers. Though known to be influential, existing evaluations have neglected in-store social dynamics and shopper behaviors. Surveys and walking interviews were used with shoppers (n = 32) at a supermarket developed through the Pennsylvania Fresh Food Financing Initiative in Philadelphia, PA. Key informant interviews with stakeholders in the supermarket's development and operations provided additional context to these shopper experiences. Data were collected in July and September 2014 and qualitatively analyzed in NVivo 10.0. Participants described how the retailer helped them adapt or cope with difficult shopping routines and how it presented a reliable high-quality option (in terms of cleanliness, orderliness, and social atmosphere) in contrast to other neighborhood retailers. Health concerns were also identified, especially among those managing chronic disease for themselves or a family member. These issues underscored multiple points of challenge required to adjust shopping and eating behavior. In-store supports that reflect these challenges are warranted to more fully address food deserts and reduce health disparities. PMID:27197735

  11. IEA Annex 26: Advanced Supermarket Refrigeration/Heat Recovery Systems

    Energy Technology Data Exchange (ETDEWEB)

    Baxter, VAN

    2003-05-19

    With increased concern about the impact of refrigerant leakage on global warming, a number of new supermarket refrigeration system configurations requiring significantly less refrigerant charge are being considered. In order to help promote the development of advanced systems and expand the knowledge base for energy-efficient supermarket technology, the International Energy Agency (IEA) established IEA Annex 26 (Advanced Supermarket Refrigeration/Heat Recovery Systems) under the ''IEA Implementing Agreement on Heat Pumping Technologies''. Annex 26 focuses on demonstrating and documenting the energy saving and environmental benefits of advanced systems design for food refrigeration and space heating and cooling for supermarkets. Advanced in this context means systems that use less energy, require less refrigerant and produce lower refrigerant emissions. Stated another way, the goal is to identify supermarket refrigeration and HVAC technology options that reduce the total equivalent warming impact (TEWI) of supermarkets by reducing both system energy use (increasing efficiency) and reducing total refrigerant charge. The Annex has five participating countries: Canada, Denmark, Sweden, the United Kingdom, and the United States. The working program of the Annex has involved analytical and experimental investigation of several candidate system design approaches to determine their potential to reduce refrigerant usage and energy consumption. Advanced refrigeration system types investigated include the following: distributed compressor systems--small parallel compressor racks are located in close proximity to the food display cases they serve thus significantly shortening the connecting refrigerant line lengths; secondary loop systems--one or more central chillers are used to refrigerate a secondary coolant (e.g. brine, ice slurry, or CO2) that is pumped to the food display cases on the sales floor; self-contained display cases--each food display case

    Urban leisure green space is a typical green open space very important for maintenance of urban ecological security and human health.Accessibility to urban leisure green spaces directly affects the quality of services for city dwellers and reflects the region's urbanization level.Accessibility to urban green spaces can be used as an indicator to assess the effectiveness of providing ecological services to residents of the green areas in current system and long-term future system.With socio-economic development,Chinese people and governments are paying much more attention to urban green spaces,and more and more citizens have the desire of contact with nature,and are willing to live close to urban green spaces.Consequently,governments plan to develop and optimize urban green space allocation to meet these demands.In this paper,a quantitative method based on landscape accessibility of green space in Hangzhou City was employed to improve index systems.Aided by GIS technique,this paper conducts analysis on the accessibility and service ability which considers the population densities of every district,applying the methods of buffer zone,minimum distance and travel.The results indicate that:(1) In Hangzhou City,on average it takes 3.8 minutes from a residential area to a urban leisure green space,and 92.11 percent of urban residents have access to a leisure green space within 10 minutes; the residential areas with poor accessibility are the outskirt areas of the city.(2) As to scenic-spot green spaces,their accessible time is 20.33 minutes.Xihu and Xixi are found to be much more accessible than other scenic spots.(3) The accessibility exhibits a structure of annulations centered around Xihu,the farther the distance is away from Xihu,the poorer the accessibility is.The work of this paper will help improve the key index system for assessing urban green spaces in China,and can provide planners and policymakers with important and valuable information for urban green space

  13. Energy performance of supermarket refrigeration and air conditioning integrated systems

    International Nuclear Information System (INIS)

    The electricity consumption for air conditioning and refrigerated cases in large supermarkets represents a substantial share of the total electricity consumption. The energy efficiency of supermarkets can be improved by optimising components design, recovering thermal and refrigerating energy, adopting innovative technology solutions, integrating the HVAC system with medium temperature and low-temperature refrigeration plants and, finally, reducing thermal loads on refrigerated cases. This study is aimed at investigating the performance of different lay-out and technological solutions and at finding the potential for improving energy efficiency over the traditional systems in different climates. In the analysis chillers and heat pumps working with R410A, medium temperature systems working with R404A and low-temperature systems working both with R404A and R744 were considered. The investigated solutions enable an annual energy saving higher than 15% with respect to the baseline solution for the considered climates.

  14. Modeling Supermarket Refrigeration Systems for Demand-Side Management

    Directory of Open Access Journals (Sweden)

    Jakob Stoustrup

    2013-02-01

    Full Text Available Modeling of supermarket refrigeration systems for supervisory control in the smart grid is presented in this paper. A modular modeling approach is proposed in which each module is modeled and identified separately. The focus of the work is on estimating the power consumption of the system while estimating the cold reservoir temperatures as well. The models developed for each module as well as for the overall integrated system are validated by real data collected from a supermarket in Denmark. The results show that the model is able to estimate the actual electrical power consumption with a high fidelity. Moreover a simulation benchmark is introduced based on the produced model for demand-side management in smart grid. Finally, a potential application of the proposed benchmark in direct control of the power/energy consumption is presented by a simple simulation example.

    Full Text Available Category management (CM is an important tool to strengthen the relationship between manufacturers and retailers. This process has been associated with large corporate retailers; however, some recent researches show that CM is open to companies of any type or size. This possibility is important in emerging markets, where neighborhood supermarkets are still representative and are often considered an alternative for manufacturers to achieve higher margins compared to big chains. In this context, the aim of this research was to analyze the results of a CM initiative in small neighborhood supermarkets from a manufacturer perspective. Data for the study comes from a food manufacturer in Brazil that implemented a CM process with 180 small retailers. A quantitative analysis was conducted in order to analyze the effect of the program on the food manufacturer’s sales and market share. Our analysis suggests an overall positive effect of the program on both, sales and market share

    The price-aggressive discount format, popularized by chains such as Aldi and Lidl, is very successful in most Western economies. Its success is a major source of concern for traditional supermarkets. Discounters not only have a direct effect on supermarkets’ market shares, they also exert considerable pressure to improve operational efficiency and/or to decrease prices. We use an empirical entry model to study the degree of intra- and inter-format competition between discounters and supermark...

    2014-01-01

    Background Supermarkets provide healthy and affordable food options while simultaneously heavily promoting energy-dense, nutrient-poor foods and drinks. Store size may impact body weight via multiple mechanisms. Large stores encourage purchasing of more food in a single visit, and in larger packages. In addition they provide greater product choice (usually at lower prices) and allow greater exposure to foods of all types. These characteristics may promote purchasing and consumption. Our objec...

    2006-01-01

    Supermarkets have responded to the growth in direct marketing and alternative agri-food networks by promoting local produce ranges, and increasingly sourcing organic produce from the UK. Thus consumers now have a choice of outlets for local and organic produce. This paper examines the implications of that choice for direct marketing in particular, and sustainable consumption in general. Mainstream and alternative models of sustainable consumption are described. The paper tests the hypothesis ...

  5. Price Dispersion and Informational Frictions: Evidence from Supermarket Purchases

    OpenAIRE

    2015-01-01

    Traditional demand models assume that consumers are perfectly informed about product characteristics, including price. However, this assumption may be too strong. Unannounced sales are a common supermarket practice. As we show, retailers frequently change position in the price rankings, thus making it unlikely that consumers are aware of all deals o¤ered in each period. Further empirical evidence on consumer behavior is also consistent with a model with price information frictions. We develop...

    Category management (CM) is an important tool to strengthen the relationship between manufacturers and retailers. This process has been associated with large corporate retailers; however, some recent researches show that CM is open to companies of any type or size. This possibility is important in emerging markets, where neighborhood supermarkets are still representative and are often considered an alternative for manufacturers to achieve higher margins compared to big chains. In this context...

  14. Proliferation networks: between Sopranos and Supermarket

    International Nuclear Information System (INIS)

    One success in the struggle against proliferation during the last decade has been that Western countries have reinforced mechanisms for control over exports of goods and technologies intended for the perfection of weapons of mass destruction. These new constraints have probably resulted in the appearance of a genuine proliferation economy, partly underground, organized around contacts between acquisition and sales networks, searching to exploit weaknesses in existing control systems to obtain wanted goods and technologies. This phenomenon is particularly worrying, because the level of technical skills attained by some suppliers is sufficiently high to guarantee that their customers will have a functional product satisfying their demand. Apart from systematic exploitation of vulnerabilities in export control systems, the capacity of these networks of suppliers to conduct their operations is reinforced by access to technologies and globalization of the market and financial tools. This article is the first of a series of two and explores the operation of these proliferation networks. The second article will be dedicated to an analysis of existing tools or other tools that can be implemented to combat them. (authors)

    Due to the environmental influences on health, the goal of this study was to describe and compare the built environment in 3 socially contrasting neighbourhoods of Buenos Aires city.In 2011 a cross-sectional study was conducted in 3 socially contrasting neighbourhoods of Buenos Aires city: Recoleta (upper class), Almagro (middle class) and Constitución (lower class). Grocery stores and food stands were surveyed as well as all suitable spaces to perform physical activity. An analysis was conducted to assess the density of every food outlet per Km2 of each neighbourhood's area and per 10000 inhabitants. 2778 food stores and 149 outdoor physical activity facilities were surveyed. A higher density was observed in Constitución for fast food restaurants (Recoleta 3.6; Almagro 2.4; Constitución 6.7) and food stands (Recoleta 4.2; Almagro 1.2; Constitución 25.7) and a lower density for outdoor physical activity facilities. Population density and area density proved to be analogous. Statistically relevant differences were observed regarding the dimension of each food outlet: grocery stores, fruit stands, pubs, restaurants and food stands, as well as in the number of food stores and outdoor physical activity facilities. The information gathered in this study could be highly useful for public health policies on healthy lifestyles, and could eventually redefine the built environment in order to improve the city's equality regarding outdoor physical activity facilities and food stores.

    Quinolones ( QNs ) including norfloxacin ( NOR ) , enrofolxacin ( ENR ), ciprofloxacin (CIP) and lomefloxacin ( LOM ) in vegetables sampled from supermarkets of Guangzhou were determined using solid phase extraction and liquid chromatography-tandem mass spectrometry. The detected frequencies of four quinolone compounds in vegetables were all above 90%. The maximum concentration of individual compounds was about 150 μg/kg. Total concentrations of quinolones ( ∑ QNs ) ranged from 10.16 to 193.25 μg/kg( D. W. ), with the average of 74.38 μg/kg and the orders for different kinds of vegetables as followed: melon-fruit vegetable ( 91.29 μg/kg ) > rhizome vegetable ( 82. 09 μg/kg ) > leafy vegetable ( 52.30 μg/kg ), and green vegetable ( 104.49 μg/kg) > pollution-free vegetable( 79.06 μg/kg) > organic vegetable ( 62.38 μg/kg) > routinely cultivated vegetable( 61.23 μg/kg).The average intake and the maximum intake of CIP + ENR for human body via vegetable consumption were 1.8 μg and 3.7 μg respectively,which were lower than those with the maximum intake limit (10 μg) via meat consumption. So it can be concluded that quinolone antibiotics in vegetables were frequently detected. Though their concentrations and health risks to human body were relatively lower, potential health risk should not be neglected for long term intake and synergism of various antibiotics.%基于超声提取-固相萃取(MW-SPE)预处理方法和高效液相色谱-串联质谱(HPLC-MS/MS)分析技术,对广州市超市蔬菜中4种喹诺酮类抗生素(QNs)的污染状况进行探查与健康风险评价.结果表明,4种喹诺酮类化合物的检出率均大于90%,蔬菜(干重,下同)中单个化合物最高含量约150μg/kg,总含量(∑QNs)在10.16~193.25μg/kg之间,平均为74.38μg/kg,其中瓜果类(91.29μg/kg)>根茎类(82.09μg/kg)>叶菜类(52.30μg/kg),绿色蔬菜(104.49μg/kg)>无公害蔬菜(79.06μg/kg)>有机蔬菜(62.38μg/kg)>普通蔬菜(61.23μg/kg

    quality of fresh-cut produce collected from shelves of supermarkets in Lavras, Brasília and São Paulo as so to guide their suppliers and consumers for the need for an increased quality control due to the risks of contamination of raw material by pathogenic and decay-causing microorganisms. 144 samples were submitted to pH, titratable acidity, soluble solid analyses and microbiological analyses (coliforms at 45ºC, Salmonella sp. and Escherichia coli. The results showed significant alterations in pH values. A decrease in acidity and soluble solids during storage was found. Contamination by coliforms at 45ºC during manufacture was verified in 50% of the presence verified. We have isolated Escherichia coli, which evidences contamination coming from inadequately cleaned raw material or by their presence on the handlers. However, no contamination by Salmonella sp. was detected. Our results indicate the need of the implementation of the Good Handling Practices for the quality control of these produce.

  18. Breakeven Prices for Photovoltaics on Supermarkets in the United States

    Energy Technology Data Exchange (ETDEWEB)

    The photovoltaic (PV) breakeven price is the PV system price at which the cost of PV-generated electricity equals the cost of electricity purchased from the grid. This point is also called 'grid parity' and can be expressed as dollars per watt ($/W) of installed PV system capacity. Achieving the PV breakeven price depends on many factors, including the solar resource, local electricity prices, customer load profile, PV incentives, and financing. In the United States, where these factors vary substantially across regions, breakeven prices vary substantially across regions as well. In this study, we estimate current and future breakeven prices for PV systems installed on supermarkets in the United States. We also evaluate key drivers of current and future commercial PV breakeven prices by region. The results suggest that breakeven prices for PV systems installed on supermarkets vary significantly across the United States. Non-technical factors -- including electricity rates, rate structures, incentives, and the availability of system financing -- drive break-even prices more than technical factors like solar resource or system orientation. In 2020 (where we assume higher electricity prices and lower PV incentives), under base-case assumptions, we estimate that about 17% of supermarkets will be in utility territories where breakeven conditions exist at a PV system price of $3/W; this increases to 79% at $1.25/W (the DOE SunShot Initiative's commercial PV price target for 2020). These percentages increase to 26% and 91%, respectively, when rate structures favorable to PV are used.

Excess dietary sodium in foods contributes to high blood pressure and cardiovascular disease. Sodium concentrations in products are an important indicator of quality. We compared the sodium content of 15,680 supermarket private-label and branded products, available in four Australian supermarkets between 2011–2013, overall and for 15 food categories. Mean sodium values were compared for: (1 all products in 2013; (2 products in both 2011 and 2013; and (3 products only in 2013. Comparisons were made using paired and unpaired t tests. In each year the proportion of supermarket private-label products was 31%–32%, with overall mean sodium content 17% (12%–23% lower than branded products in 2013 (p ≤ 0.001. For products available in both 2011 and 2013 there was a ≤2% (1%–3% mean sodium reduction overall with no difference in reformulation between supermarket private-label and branded products (p = 0.73. New supermarket private-label products in 2013 were 11% lower in sodium than their branded counterparts (p = 0.02. Supermarket private-label products performed generally better than branded in terms of their sodium content. Lower sodium intake translates into lower blood pressure; some supermarket private-label products may be a good option for Australians needing to limit their sodium intake.

Can Urban Engineering be applied to promote a friendlier mobility, that should be not only environment and climate friendly, but user friendly as well? And how? A "people friendly" accessibility approach is presented and conceived as a solution to better integrate land uses with the transport system, satisfying people's expectations (especially those of vulnerable users to easily reach the opportunities they wish to engage with.  The case study of Amsterdam, as walkable and cycle friendly city, is briefly presented and reveal good practices in the field of urban and mobility planning.  Finally, an isochronical accessibility analysis of Amsterdam is applied: it represent catchment areas of railways stations and of supermarkets, and it highlights how much the structure of the city supports bicycle use.

    2014-06-01

    The purpose of this study was to determine the prevalence of children's food requests, and parents' experiences of food marketing directed towards children, in the supermarket environment. A mixed-method design was used. Firstly, intercept interviews were conducted with parents accompanied by a child/children on exiting supermarkets (sampled from a large regional centre in Australia). Parents were asked about the prevalence and types of food requests by child/children during their supermarket visit and whether they purchased these foods. Secondly, focus groups (n = 13) and telephone interviews (n = 3) were conducted exploring parents' experiences of supermarket shopping with children and the impact of child-directed marketing. Of the 158 intercept survey participants (30% response rate), 73% reported a food request during the supermarket visit. Most requested food items (88%) were unhealthy foods, with chocolate/confectionery being the most common food category requested (40%). Most parents (70%) purchased at least one food item requested during the shopping trip. Qualitative interviews identified four themes associated with food requests and prompts in the supermarket: parents' experience of pester power in the supermarket; prompts for food requests in the supermarket; parental responses to pestering in the supermarket environment, and; strategies to manage pestering and minimize requests for food items. Food requests from children are common during supermarket shopping. Despite the majority of the requests being unhealthy, parents often purchase these foods. Parents reported difficulties dealing with constant requests and expressed desire for environmental changes including confectionery-free checkouts, minimization of child friendly product placement and reducing children's exposure to food marketing.

    2001-01-01

    Product tampering, as detailed by the Federal Anti-Tampering Act of 1983 (1), is a felony punishable by both fine and imprisonment. The rationale for product tampering ranges from pranks and attention seeking acts to extortion, terrorism, and homicide. One such case submitted for analysis involved four medical syringes found in a supermarket and suspected of being used to tamper with various products. One of the syringes was found piercing a pear while the other three syringes were found with needles exposed in other parts of the supermarket. Microscopic analysis was used to collect residue from the syringe barrels and the pear. A multidiscipline approach involving SLM, PLM, including microchemical analysis, FTIR, and GC/MS analyses, performed on the residual liquid found in the syringe barrels and in the suspect pear, confirmed the presence of cocaine. This multidisciplinary approach is often necessary when there is a possible health risk to the public and rapid response is important. With this approach, it was quickly determined which drugs or poisons were used in this tampering. PMID:11210900

  10. Energy-efficient lighting applications in a supermarket environment

    Energy Technology Data Exchange (ETDEWEB)

    Dammer, D.

    1996-01-01

    This paper describes the application of energy-efficient lighting in a retail environment, specifically a supermarket. It will reveal the general theory behind Big V`s chosen lighting design, and then discuss two examples of the application: one, a retrofit to an existing supermarket; the other, the adaption of the design to a new store. The factors that influence Big V`s lighting design are: (1) the best presentation of product for merchandising purposes, and (2) the lowest operating cost. These two factors can often be mutually exclusive. For merchandising purposes, the best design would make the product `jump off the shelf` at a customer, preferably into his/her shopping cart. Such an arrangement would include high footcandle levels along with a very high color rendering index (CRI). To design only to these requirements would result in very high original and operating costs for the lighting system. However, to base the design on cost considerations alone would result in low light levels at a very low CRI. Since neither option is acceptable, Big V`s design is a compromise, combining the best light quality at a reasonable cost.

  12. Investigation of Energy-Efficient Supermarket Display Cases

    Energy Technology Data Exchange (ETDEWEB)

    Walker, D.H.

    2005-01-21

    Supermarkets represent one of the largest energy-intensive building groups in the commercial sector, consuming 2 to 3 million kWh/yr per store (ES-1). Over half of this energy use is for the refrigeration of food display cases and storage coolers. Display cases are used throughout a supermarket for the merchandising of perishable food products. The cases are maintained at air temperatures ranging from -10 to 35 F, depending upon the type of product stored. The operating characteristics and energy requirements of the refrigeration system are directly related to the refrigeration load. The sources of the display case refrigeration load consist of: (1) Moist and warm air infiltration through the open front of the case--air curtains are employed to inhibit this infiltration, but some ambient air is entrained, which adds a substantial portion to the refrigeration load. (2) Heat conduction through case panels and walls. (3) Thermal radiation from the ambient to the product and display case interior. (4) Internal thermal loads--the use of lights, evaporator fans, periodic defrosts, and antisweat heaters adds to the refrigeration load of the display case as well as directly consuming electric energy. The impact of each of these elements on the refrigeration load is very dependent upon case type (Figure ES-1). For example, air infiltration is the most significant portion of the refrigeration load for open, multi-deck cases, while radiation is the largest part of the load for tub-type cases. The door anti-sweat heaters represent a major share of the refrigeration load for frozen food door reach-in cases. Figure ES-2 shows the distribution of display cases in a typical supermarket (ES-2). Open, multi-deck, medium temperature display cases typically comprise about half of the refrigerated fixtures in a store (ES-3). In addition, medium temperature fixtures and storage coolers account for roughly 70 to 75 percent of the total store refrigeration load with open, multi-deck cases

  16. AGENT AND RADIO FREQUENCY IDENTIFICATION BASED ARCHITECTURE FOR SUPERMARKET INFORMATION SYSTEM

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available In recent years the acceptance of Radio Frequency Identification (RFID technology in business environments has been increasing rapidly due to its competitive business value. Adopting a suitable RFID-based information system has become increasingly important for supermarkets. However, most supermarkets still use conventional barcode-based systems to manage their information processes, which are consistently reported as one of the most unenthusiastic aspects of supermarket shopping for both customers and management. We propose an RFID agent-based architecture that adopts intelligent agent technology with an RFID based applications. RFID provides capability to uniquely identify an object within a supermarket area, while agents are able to establish a channel of communication which can be used to facilitate communications between a RFID device and supermarket back-end system. The proposed framework includes a design of intelligent mobile shopping cart equipped with both RFID and agent technologies. As a result of using the proposed RFID agent based architecture, the customer shopping experience will be improved due to ease of retrieving of the detailed information on items and quick checkout by scanning all items at once, thus eliminating queues. From supermarket management point of view the proposed architecture will reduce the cost of operation e.g., decreasing cost of goods sold which comes in the form of labor efficiency in areas of checkout operation, inventory management and alerting the supermarket management when a certain product is running out of stock and needs to be restocked.

  17. Control optimizations for heat recovery from CO2 refrigeration systems in supermarket

    International Nuclear Information System (INIS)

    Highlights: • Application of supermarket energy control system model. • Heat recovery from CO2 refrigeration system in supermarket space conditioning. • Effect of pressure controls of CO2 refrigeration system on heat recovery potentials. • Control optimization of CO2 refrigeration system for heat recovery in supermarket. - Abstract: A modern supermarket energy control system has a concurrent need for electricity, food refrigeration and space heating or cooling. Approximately 10% of this energy is for conventional gas-powered heating. In recent years, the use of CO2 as a refrigerant in supermarket systems has received considerable attention due to its negligible contribution to direct greenhouse gas emissions and excellent thermophysical and heat transfer properties. CO2 refrigeration systems also offer more compact component designs over a conventional HFC system and heat recovery potential from compressor discharge. In this paper, the heat recovery potential of an all-CO2 cascade refrigeration system in a supermarket has been investigated using the supermarket simulation model “SuperSim” developed by the authors. It has been shown that at UK weather conditions, the heat recovery potential of CO2 refrigeration systems can be increased by increasing the condenser/gas cooler pressure to the point where all the heat requirements are satisfied. However, the optimum level of heat recovery will vary during the year and the control system should be able to continuously optimize this level based on the relative cost of energy, i.e., gas and electricity

    Full Text Available Abstract Background The burden of cardiovascular disease (CVD in Britain is concentrated in inner-city areas such as Sandwell, which is home to a diverse multi-ethnic population. Current guidance for CVD risk screening is not established, nor are there specific details for ethnic minorities. Given the disparity in equitable healthcare for these groups, we developed a 'tailored' and systematic approach to CVD risk screening within communities of the Sandwell locality. The key anticipated outcomes were the numbers of participants from various ethnic backgrounds attending the health screening events and the prevalence of known and undiagnosed CVD risk within ethnic groups. Methods Data was collected during 10 health screening events (September 2005 and July 2006, which included an assessment of raised blood pressure, overweight, hyperlipidaemia, impaired fasting glucose, smoking habit and the 10 year CVD risk score. Specific features of our approach included (i community involvement, (ii a clinician who could deliver immediate attention to adverse findings, and (iii the use of an interpreter. Results A total of 824 people from the Sandwell were included in this study (47% men, mean age 47.7 years from community groups such as the Gujarati Indian, Punjabi Indian, European Caucasian, Yemeni, Pakistani and Bangladeshi. A total of 470 (57% individuals were referred to their General Practitioner with a report of an increased CVD score – undetected high blood pressure in 120 (15%, undetected abnormal blood glucose in 70 (8%, undetected raised total cholesterol in 149 (18%, and CVD risk management review in 131 (16%. Conclusion Using this systematic and targeted approach, there was a clear demand for this service from people of various ethnic backgrounds, of whom, one in two needed review from primary or secondary healthcare. Further work is required to assess the accuracy and clinical benefits of this community health screening approach.

    Full Text Available Objective: Local anesthetics are the most commonly used drugs in routine dentistry. Although they are considered effective and safe in controlling pain during dental procedures, complications related to their use appear inevitable. Many dentists use these drugs routinely but are unaware of the dose calculations required and the maximum safe and effective dose of the drug. Materials and Methods: This study was aimed to determine the knowledge that general dental practitioners and dental specialists, in three different cities in India, have regarding dose calculations and the maximum-dose required of the most commonly used local anesthetics. A one page survey questionnaire was used in this study and data were analyzed using standard SPSS statistical program version 11, software (SPSS Inc. Chicago, Illinois, USA. Results: The respondents comprised 71.4% general dental practitioners and 28.5% dental specialists, with ages ranging from 26 to 50 years; Nearly 75% of the total respondent was males and 25% females. Nearly 69% of the respondents were unaware of the maximum recommended dose for use on adult, healthy patients and 81% were still confused about the maximum numbers of syringes containing 2% lignocaine with adrenaline that can be given to a patient. A total of 49% of general dental practitioners and specialists do not perform aspiration when injecting local anesthetics, whereas only 38% performed the aspiration in inferior nerve block technique, while only 12% performed aspiration in all types of injection techniques. A high percentage of the dentists (84% who responded are unaware of how to calculate the local anesthetic dose and 31% of them encountered complications during, or after, local anesthetic administration. Conclusion: General practitioners and dental specialists appear to have an inadequate knowledge about local anesthetics maximum-dose and dose calculations; further educational courses are recommended to update them regarding such

  2. Integration of energy efficient technologies in UK supermarkets

    International Nuclear Information System (INIS)

    The purpose of this paper is twofold: to determine if the integration of energy efficient technologies in UK supermarkets can determine consumer behaviour, and to establish if such activities can help satisfying the environmental elements of the clients corporate social responsibilities (CSR) in an attempt to create a competitive advantage. A literature review of existing material considered the history and drivers of sustainability, the types of energy efficient technologies and factors concerning CSR and consumer behaviour in relation to the supermarket industry. Interviews with 15 senior store managers were recorded and transcribed. The opinions of the senior store managers were then sought and analysed using qualitative research software NVivo software. Validity of the data was achieved at a later stage through workshops. The results of this paper suggested that there is a definite lack of awareness and knowledge amongst customers regarding energy efficient technologies. From the findings, it was further established that the key driver for retailers who integrate energy efficient technologies is fiscal incentives, although it was suggested some retailers use CSR strategies to report there are environmental achievements it was ultimately found that cost savings were the primary driver. - Highlights: • The effect of sustainability towards consumer behaviour was explored. • Majority of consumers are unaware of energy efficient technologies. • Energy efficient technologies do not determine or create shifts in paradigm in consumer actions. • Stores are driven to integrate energy efficient technologies more by government legislation. • Participants were clear in making the point that their image and reputation was based on trust

    2014-01-01

    In order to make a quantitative study about the impact of rail transit construction on the spatial pat-tern of city accessibility in Jinhua,it was firstly used the software Arc GIS 9. 3 to carry out an empirical re-search about the accessibility of city in Jinhua based on the highway network structure and calculations of opti-mal road routes and time to city of Jinhua. With the generated accessibility diffusion graph before and after the rail transit construction of Jinhua,a comparison and analysis of the graph and chart was made and analyzed. The result showed that the overall accessibility of cities was fairly good before the rail transit construction in Jinhua,and currently the accessibility time of 87% of Jinhua area was within 1 h. The accessibility of all the cities of Jinhua would be optimized on different levels as rail transit would be constructed. However,as to the regional distribution,the accessibility diffusion graph took on a laver structure taken cities as the center. The regions of better accessibility was showed to be distributed in two axes,specifically including″Lanxi-Jinhua City-Wuyi-Yongkang″ and ″ Pujiang-Yiwu-Dongyang-Pan′ an″. Despite all of this,the regions of worse accessibility were distributed in a zone between the two axes,and the accessibility of all the cities in Jin-hua was not going to be markedly improved as rail transit been constructed. Because rail transit lines in Jinhua would not run through Pan′an,the accessibility of the county region and the region between Pan′an and any other city had almost no change. On the basis of foregoing analysis,some corresponding optimization measures were suggested.%为了定量分析轨道交通建设对金华城镇可达性的影响,首先基于金华市公路路网结构和最短时间路径选择算法,运用 Arc GIS 9.3软件对轨道交通建设前后的城镇可达性进行了对比分析.结果表明:金华各城镇的整体可达性较好,其中87%

    2009-07-01

    Full Text Available Abstract Introduction In light of overwhelming evidence that access to sterile injection equipment reduces incidence of injection-attributable bloodborne disease without encouraging drug use, many localities have authorized sterile syringe access programs (SAPs, including syringe exchange and pharmacy-based initiatives. Even where such interventions are clearly legal, many law enforcement officers are unaware of the public health benefits and legal status of these programs and may continue to treat the possession of injection equipment as illegal and program participation as a marker of illegal behavior. Law enforcement practice can impede SAP utilization and may increase the risk of needlestick injury (NSI among law enforcement personnel. Many SAPs conduct little or no outreach to law enforcement, in part because they perceive law enforcement actors as unreceptive to health-promotion programs targeting drug users. Case description We report on a brief training intervention for law enforcement personnel designed to increase officer knowledge of and positive attitudes towards SAPs by bundling content that addresses officer concerns about infectious disease and occupational safety with information about the legality and public health benefits of these programs. Pilot trainings using this bundled curriculum were conducted with approximately 600 officers in three US cities. Discussion and evaluation Law enforcement officers were generally receptive to receiving information about SAPs through the bundled curriculum. The trainings led to better communication and collaboration between SAP and law enforcement personnel, providing a valuable platform for better harmonization of law enforcement and public health activities targeting injection drug users. Conclusion The experience in these three cities suggests that a harm reduction training curriculum that bundles strategies for increasing officer occupational safety with information about the legality

    2013-09-01

    A large body of literature has reported differences in exposure to environments supporting either healthy (e.g. supermarkets) or unhealthy (e.g. fast food outlets) dietary choices by neighborhood characteristics. We explored the associations of both supermarkets and fast food outlets availability with neighborhood characteristics, and clustering of these two outlet types in a largely rural state. Compared to block groups without a supermarket, those with a supermarket had a significantly higher income, higher housing value, larger population with high school education and above, lower minority population and lower population living below poverty even after controlling for urbanicity and population density of census block groups. Surprisingly, a similar relationship was found for block groups with and without fast food outlets. This was due to spatial co-occurrence and clustering of fast food outlets around supermarket locations. Hence, future studies exploring the associations of food environment with diet or diet-related health outcome should concurrently examine all aspects of food environment (healthy and unhealthy).

    Dixon-Hardy, Darron W; Curran, Beverley A

    2009-03-01

    Packaging waste is a contributing factor to the large quantity of waste that is sent to landfill in the UK. This research focuses on waste from the secondary packaging sector in the UK. In particular, supermarkets were investigated as they supply a large section of consumers with their grocery and other requirements and generate high quantities of packaging waste due to the high turnover within the store. In general, supermarkets use either metal cages or wooden pallets to transport products from depot to store. Investigation shows that packaging waste produced when using the wooden pallets is greater than for metal cages but the use of wooden pallets allows for greater versatility when in the store. The type of transit packaging used depends on what the products are initially packaged in and how the supermarket supply chain works. All cardboard and high-grade plastic is recycled but, depending on the facilities at the stores, the low-grade plastic can be recycled as well. This paper details types of packaging used within the supermarket secondary packaging sector and how waste can be reduced. To reduce the amount of packaging waste produced by the supermarkets, the products will have to be wrapped differently by the producers so that less packaging is needed in transit. PMID:18976897

    In view of the interest in the role of foodstuffs in improving wellbeing and health, the object of this study is to distinguish consumer typologies in Temuco, La Araucanía Region, Chile, according to their preferences for different functional ingredients, flavouring, colouring and price in yoghurt. A semi-structured survey was applied to 400 supermarket customers. The respondents ordered eight alternative yoghurts according to their preferences, with different functional ingredients (fibre, antioxidants), flavourings (sugar, sweetener), colouring (natural, artificial) and three price options, for a conjoint analysis with fractional factorial design. Variables affecting knowledge of "functional food" were evaluated using a binomial logit model. It was determined by conjoint analysis that in general a preference existed for yoghurt containing fibre, sweetener, natural colouring, and at the lowest price. Three typologies were distinguished by analysis of hierarchical conglomerates: the majority segment (48.8%) displayed a greater preference for fibre; the second (41.7%) also preferred fibre, but gave first priority to artificial colouring and preferred a higher price. The minority (9.5%) was the only segment to prefer antioxidants. The typologies differed significantly in satisfaction with their food-related life, knowledge of the function of fibre and presence of cancer and obesity in some member of the respondent's family. The binomial logit model was significant (P < 0.01), indicating that if the consumer has a job or has had access to information on functional foods, the probability increased of knowledge of what these mean. There was thus majority acceptance of yoghurt enriched with fibre and with added sweetener. PMID:21866689

    Full Text Available Abstract Background Supermarkets play a major role in influencing the food purchasing behaviours of most households. Snack food exposures within these stores may contribute to higher levels of consumption and ultimately to increasing levels of obesity, particularly within socioeconomically disadvantaged neighbourhoods. We aimed to examine the availability of snack food displays at checkouts, end-of-aisle displays and island displays in major supermarket chains in the least and most socioeconomically disadvantaged neighbourhoods of Melbourne. Methods Within-store audits of 35 Melbourne supermarkets. Supermarkets were sampled from the least and most socioeconomically disadvantaged suburbs within 30 km of the Melbourne CBD. We measured the availability of crisps, chocolate, confectionery, and soft drinks (diet and regular at the checkouts, in end-of-aisle displays, and in island bin displays. Results Snack food displays were most prominent at checkouts with only five stores not having snack foods at 100% of their checkouts. Snack foods were also present at a number of end-of-aisle displays (at both the front (median 38% and back (median 33% of store, and in island bin displays (median number of island displays: 7; median total circumference of island displays: 19.4 metres. Chocolate items were the most common snack food item on display. There was no difference in the availability of these snack food displays by neighbourhood disadvantage. Conclusions As a result of the high availability of snack food displays, exposure to snack foods is almost unavoidable in Melbourne supermarkets, regardless of levels of neighbourhood socioeconomic disadvantage. Results of this study could promote awareness of the prominence of unhealthy food items in chain-brand supermarkets outlets.

    Supermarket-based interventions are one approach to improving the local food environment and reducing obesity and chronic disease in low-income populations. We implemented a multicomponent intervention that aimed to reduce environmental barriers to healthy food purchasing in a supermarket in Southwest Baltimore. The intervention, Eat Right-Live Well! used: shelf labels and in-store displays promoting healthy foods, sales and promotions on healthy foods, in-store taste tests, increasing healthy food products, community outreach events to promote the intervention, and employee training. We evaluated program implementation through store environment, taste test session, and community event evaluation forms as well as an Employee Impact Questionnaire. The stocking, labeling, and advertising of promoted foods were implemented with high and moderate fidelity. Taste test sessions were implemented with moderate reach and low dose. Community outreach events were implemented with high reach and dose. Supermarket employee training had no significant impact on employees' knowledge, self-efficacy, or behavioral intention for helping customers with healthy purchasing or related topics of nutrition and food safety. In summary, components of this intervention to promote healthy eating were implemented with varying success within a large supermarket. Greater participation from management and employees could improve implementation. PMID:26296352

    Clark, J. [National Renewable Energy Laboratory (NREL), Golden, CO (United States)

    2015-03-01

    Supermarkets are energy-intensive buildings that consume the greatest amount of electricity per square foot of building of any building type in the United States and represent 5% of total U.S. commercial building primary energy use (EIA 2005). Refrigeration and heating, ventilation, and air-conditioning (HVAC) systems are responsible for a large proportion of supermarkets’ total energy use. These two systems sometimes work together and sometimes compete, but the performance of one system always affects the performance of the other. To better understand these challenges and opportunities, the Commercial Buildings team at the National Renewable Energy Laboratory investigated several of the most promising strategies for providing energy-efficient HVAC for supermarkets and quantified the resulting energy use and costs using detailed simulations. This research effort was conducted on behalf of the U.S. Department of Energy (DOE) Commercial Building Partnerships (CBP) (Baechler et al. 2012; Parrish et al. 2013; Antonopoulos et al. 2014; Hirsch et al. 2014). The goal of CBP was to reduce energy use in the commercial building sector by creating, testing, and validating design concepts on the pathway to net zero energy commercial buildings. Several CBP partners owned or operated buildings containing supermarkets and were interested in optimizing the energy efficiency of supermarket HVAC systems in hot-humid climates. These partners included Walmart, Target, Whole Foods Market, SUPERVALU, and the Defense Commissary Agency.

  8. Determination of biogas generation potential as a renewable energy source from supermarket wastes

    International Nuclear Information System (INIS)

    Highlights: • Disposal of supermarket wastes in landfills may contribute to environmental pollution. • High methane yields can be obtained from supermarket wastes by anaerobic co-digestion. • Fruit and vegetable wastes or dairy products wastes could individually be handled by a two-stage anaerobic process. • Buffering capacity, trace metal and C/N ratio are essential for digestion of supermarket wastes. - Abstract: Fruit, vegetable, flower waste (FVFW), dairy products waste (DPW), meat waste (MW) and sugar waste (SW) obtained from a supermarket chain were anaerobically digested, in order to recover methane as a source of renewable energy. Batch mesophilic anaerobic reactors were run at total solids (TS) ratios of 5%, 8% and 10%. The highest methane yield of 0.44 L CH4/g VSadded was obtained from anaerobic digestion of wastes (FVFW + DPW + MW + SW) at 10% TS, with 66.4% of methane (CH4) composition in biogas. Anaerobic digestion of mixed wastes at 5% and 8% TS provided slightly lower methane yields of 0.41 and 0.40 L CH4/g VSadded, respectively. When the wastes were digested alone without co-substrate addition, the highest methane yield of 0.40 L CH4/g VSadded was obtained from FVFW at 5% TS. Generally, although the volatile solids (VS) conversion percentages seemed low during the experiments, higher methane yields could be obtained from anaerobic digestion of supermarket wastes. A suitable carbon/nitrogen (C/N) ratio, proper adjustment of the buffering capacity and the addition of essential trace nutrients (such as Ni) could improve VS conversion and biogas production yields significantly

  10. Estimated Fresh Produce Shrink and Food Loss in U.S. Supermarkets

    Directory of Open Access Journals (Sweden)

    Jean C. Buzby

    2015-08-01

    Full Text Available Data on fresh fruit and vegetable shrink in supermarkets is important to help understand where and how much shrink could potentially be reduced by supermarkets to increase their profitability. This study provides: (1 shrink estimates for 24 fresh fruits and 31 fresh vegetables in U.S. supermarkets in 2011 and 2012; and (2 retail-level food loss. For each covered commodity, supplier shipment data was aggregated from a sample of 2900 stores from one national and four regional supermarket retailers in the United States, and this sum was then compared with aggregated point-of-sale data from the same stores to estimate the amount of shrink by weight and shrink rates. The 2011–2012 average annual shrink rates for individual fresh vegetables varied from 2.2 percent for sweet corn to 62.9 percent for turnip greens and for individual fresh fruit ranged from 4.1 percent for bananas to 43.1 percent for papayas. When these shrink estimates were used in the Loss-Adjusted Food Availability data series, annual food loss for these commodities totaled 5.9 billion pounds of fresh fruit and 6.1 billion pounds of fresh vegetables. This study extends the literature by providing important information on where and how much shrink could potentially be reduced. Precise comparisons across studies are difficult. This information, combined with information on available and cost-effective technologies and practices, may help supermarkets target food loss reduction efforts though food loss will never be zero.

  13. The virtual supermarket: An innovative research tool to study consumer food purchasing behaviour

    Directory of Open Access Journals (Sweden)

    Steenhuis Ingrid HM

    2011-07-01

    Full Text Available Abstract Background Economic interventions in the food environment are expected to effectively promote healthier food choices. However, before introducing them on a large scale, it is important to gain insight into the effectiveness of economic interventions and peoples' genuine reactions to price changes. Nonetheless, because of complex implementation issues, studies on price interventions are virtually non-existent. This is especially true for experiments undertaken in a retail setting. We have developed a research tool to study the effects of retail price interventions in a virtual-reality setting: the Virtual Supermarket. This paper aims to inform researchers about the features and utilization of this new software application. Results The Virtual Supermarket is a Dutch-developed three-dimensional software application in which study participants can shop in a manner comparable to a real supermarket. The tool can be used to study several food pricing and labelling strategies. The application base can be used to build future extensions and could be translated into, for example, an English-language version. The Virtual Supermarket contains a front-end which is seen by the participants, and a back-end that enables researchers to easily manipulate research conditions. The application keeps track of time spent shopping, number of products purchased, shopping budget, total expenditures and answers on configurable questionnaires. All data is digitally stored and automatically sent to a web server. A pilot study among Dutch consumers (n = 66 revealed that the application accurately collected and stored all data. Results from participant feedback revealed that 83% of the respondents considered the Virtual Supermarket easy to understand and 79% found that their virtual grocery purchases resembled their regular groceries. Conclusions The Virtual Supermarket is an innovative research tool with a great potential to assist in gaining insight into food

  14. Prediction and analysis of the seasonal performance of tri-generation and CO2 refrigeration systems in supermarkets

    International Nuclear Information System (INIS)

    Highlights: ► Integration model of a trigeneration with CO2 refrigeration systems in supermarket. ► Validation of the developed integration model with site and laboratory measurement. ► Application of the trigeneration system in power generation and space conditioning. ► Performance analysis and comparison of the integrated system in supermarket. - Abstract: A modern supermarket energy control system has a concurrent need for electricity, space heating or cooling, and food refrigeration. The power supply to the supermarket is primarily from the national grid, where losses in efficiency are due to the processes of energy conversion and transmission. Combined heat and power (CHP) offers the potential to locally produce electrical power and heating which could save energy and reduce CO2 emissions in the long run. During the summer months, as the space heating requirement in a supermarket is relatively small, the energy efficiency of a CHP installation can be improved by using excess thermal energy to drive a sorption refrigeration system to provide space cooling or refrigeration. This process is also known as tri-generation. In recent years, the use of CO2 as a refrigerant in supermarkets has received considerable attention due to its negligible contribution to direct greenhouse gas emissions and excellent thermophysical and heat transfer properties. Consequently, the application of a tri-generation system in a supermarket with CO2 refrigeration merits further investigation. In this paper, to evaluate the performance of a tri-generation system in the supermarket, a previously tested 80 kWe microturbine device was applied into an operational supermarket to generate power and provide space heating and cooling through exhaust heat. The performance evaluation and comparison for this tri-generation application is based on the prediction from an integrated model of supermarket energy control, cascade CO2 refrigeration and tri-generation systems. The results from

  14. Trigeneration in food retail: An energetic, economic and environmental evaluation for a supermarket application

    International Nuclear Information System (INIS)

    This paper presents results on the evaluation of energy utilisation efficiency and economic and environmental performance of a micro-gas turbine (MGT) based trigeneration system for supermarket applications. A spreadsheet energy model has been developed for the analysis of trigeneration systems and a 2800 m2 sales area supermarket was selected for the feasibility study. Historical energy demand data were used for the analysis, which considered factors such as the fraction of the heat output used to drive the absorption chillers, the chiller COP and the difference between electricity and gas prices. The results showed that energy and environmental benefits can be obtained from the application of trigeneration systems to supermarkets compared to conventional systems. The payback period of natural gas driven trigeneration systems and greenhouse gas emissions savings will depend on the relative gas and electricity prices and the COP of the vapour compression and absorption systems. It was also shown that operation at full electrical output gives a better performance than a heat load-following strategy due to the reduction of the electrical generation efficiency of the MGT unit at part load conditions.

    Schnettler, Berta; Miranda, Horacio; Lobos, Germán; Sepúlveda, José; Denegri, Marianela

    2011-06-01

    The objective of this study was to distinguish different types of consumers according to their level of ethnocentrism in relation to the consumption of foodstuffs in central-southern Chile. To do this a modification of the CETSCALE (Consumer Ethnocentric Tendencies Scale) was applied through direct survey of 800 habitual supermarket shoppers in two cities in central-southern Chile. The modified CETSCALE presented a sufficient level of internal consistency and there were three factors which included the 17 items of the scale. Five typologies of consumer with different degrees of ethnocentrism were distinguished by cluster analysis, based on the values of the factors and items in the CETSCALE. The composition of the typologies of consumers were related to the city and zone of residence, age, socioeconomic level, self-declared life-style, ethnic origin, knowledge of the origin of the foodstuffs purchased, frequency of purchase of imported foodstuffs and reasons for rejection in the case of a low purchase frequency. It may therefore be concluded that different levels of ethnocentrism exist in the consumption of foodstuffs, related with some socio-demographic characteristics of consumers and their attitudes to imported foodstuffs.

    Full Text Available This study is the first in the Philippines to conduct a comprehensive assessment of the prevalence of bacterial pathogens and somatic phages in retailed fresh produce used in salad preparation, namely, bell pepper, cabbage, carrot, lettuce, and tomato, using culture and molecular methods. Out of 300 samples from open air and supermarkets, 16.7% tested positive for thermotolerant Escherichia coli, 24.7% for Salmonella spp., and 47% for somatic phages. Results show that counts range from 0.30 to 4.03 log10 CFU/g for E. coli, 0.66 to ≥2.34 log10 MPN/g for Salmonella spp., and 1.30 to ≥3.00 log10 PFU/g for somatic phages. Statistical analyses show that there was no significant difference in the microbial counts between open air and supermarkets (α=0.05. TaqMan and AccuPower Plus DualStar real-time polymerase chain reaction (RT-PCR was used to confirm the presence of these organisms. The relatively high prevalence of microorganisms observed in produce surveyed signifies reduction in shelf-life and a potential hazard to food safety. This information may benefit farmers, consumers, merchants, and policy makers for foodborne disease detection and prevention.

  16. Energy performance of supermarket refrigeration and air conditioning integrated systems working with natural refrigerants

    International Nuclear Information System (INIS)

    The current trends in commercial refrigeration aim at reducing the synthetic refrigerant charge, either by minimising the internal volume of the circuit or by utilising natural refrigerants, and at energy saving. The energy efficiency of supermarkets can be improved by optimising components design, recovering thermal and refrigerating energy, adopting innovative technology solutions, integrating the HVAC system with medium temperature and low temperature refrigeration plants and, finally, reducing thermal loads on refrigerated cases. This study aims at investigating the performance of different lay-out and technological solutions where only natural refrigerants are used and at finding the potential for improving energy efficiency over the traditional systems in different climates. In the analysis, chillers and heat pumps working with ammonia or propane, medium temperature systems working with ammonia or propane and carbon dioxide as heat transfer fluid or with carbon dioxide as the refrigerant and low temperature systems working with carbon dioxide are considered and benchmarked with a state-of-the-art HFCs based plant. The most efficient investigated solution enables an annual energy saving higher than 15% with respect to the baseline solution for all the considered climates. - Highlights: ► Different natural refrigerants supermarket HVAC and R integrated systems are analysed. ► Some of the proposed solutions offer a significant benefit over the baseline one. Up to 18.7% energy saving is achieved in the considered climates. ► The refrigeration unit condensation by the AC chiller offers the poorest results.

    Full Text Available This paper examined the relationships between growers’ choice of market channel (emphasizing the supermarket market-channel versus others, technology use, and grower characteristics such as human capital and farm size. Three key findings emerged. First, both tomato and lettuce growers selling to the supermarket market-channel had more human capital than those not participating. Second, while farm size was important in whether lettuce growers sell to supermarkets, it was not important for tomato growers. Third, technology use was significantly more capital-intensive among lettuce growers selling to the supermarket channels, however, that was generally not the case for tomato growers. These results are important to agribusiness researchers and policymakers interested in technology design and research and extension to enable producers to adapt to the needs of changing agrifood markets, with new requirements of attributes of products and transactions, which in turn have implications for technology adoption and human capital investment among growers. This is particularly pressing in places like Brazil where the market for horticultural products is changing quickly, conditioned by the rapid rise of supermarkets.Este artigo analisa as relações entre a escolha dos canais de distribuição dos produtores (enfatizando distribuição por meio de supermercados versus outros canais, o uso da tecnologia e as características dos produtores como capital humano e tamanho da propriedade.

    Supermarkets are commercial buildings with major energy consumption and contribute also to relatively large direct emissions of greenhouse (GHG) through emissions of refrigerants from the refrigeration plants and the air conditioning system installed. The huge majority of these systems, which are installed in European supermarkets, are applying HFC-404A as working fluid. Average annual leakage rates in Europe are in the range of 15-20 % of the total charge. Worldwide the figure is about 30 % and HCFC-22 being the main refrigerant in use. Restrictions on the use of synthetic refrigerants are coming into force in several countries. There is a need for a natural refrigerant which allows for a safe investment in efficient refrigeration systems which will not be forced to be retrofitted by legislation in the future. Systems applying R-744 as the only refrigerant have been developed and more than 500 supermarkets exist in Europe, mainly in northern and mid-European countries. However, the systems still have large potential in development with respect to energy efficiency, heat recovery and cost efficiency. The paper describes the calculation method to identify the possible annual energy savings for different supermarket systems layout. The adoption of non-controlled ejectors and additional function such as heat recovery are evaluated. Results show relevant improvements in system efficiency when heat recovery has been adopted. Ejector usage is not widely spread at the moment. Thus, a theoretical analysis applying the programming language Modelica has been carried out. (orig.)

    Cooling of the chiller condensers in supermarkets can be performed in different ways. To start with, the condensers can be cooled by use of outdoor air in dry coolers, but the ventilation air can also perform the cooling, totally or partially. In such a way the total or a part of the heating demand of the supermarket might be covered. A third alternative for condenser cooling is use of district cooling. However, in such a case the possibility to heat the supermarket by heat recovery is lost. The purpose of this study is to outline when district cooling offers the most advantageous alternative for condenser cooling in comparison to the other alternatives. This assessment is to be performed taking costs, electricity use and environmental impact into consideration separately. The results from calculations for a case supermarket show that the price for district cooling is generally to high for making it profitable for a supermarket to cool the condensers by district cooling. However, cooling the condensers by district cooling might lead to savings for the supermarket, both in terms of investments and use of electricity. This leads to the fact that cooling the condensers by district cooling could offer a profitable alternative for the supermarket, if the prices are adapted to this type of costumer. Hopefully, such a business could be profitable for the producers of district cooling as well. In addition, there are other advantages associated with condenser cooling by district cooling, which are hard to evaluate in economic terms. When it comes to the comparison of electricity use, it is shown that condenser cooling by district cooling is the alternative that uses least electricity in a national point of view, if the district cooling is produced by a deep-water source. In this comparison, the electricity used for production of district cooling and district heating is included as well. If district cooling is co-produced with district heating in heat pumps, the result is

    A variety of ready-to-cook meat products available in Indian supermarkets (mutton mince, chicken mince, chicken chunks, and chicken legs) were studied. The samples were irradiated (2.5 kGy), or left untreated as control, and stored at 0-3 {sup o}C for up to 21 days. The effect of irradiation on the microbiological, chemical, and sensory properties was evaluated at intervals during the storage period. Irradiated samples had a longer shelf-life at 0-3 {sup o}C compared with the corresponding non-irradiated samples. Fecal coliforms were eliminated by irradiation treatment. Radiation processed samples had lower counts of Staphylococcus spp. There were no significant organoleptic changes in irradiated samples stored at chilled temperatures.

    The Fault Detection and Isolation (FDI) using the Unknown Input Observer (UIO) for a supermarket refrigeration system is investigated. The original system's state $T_{goods}$ (temp. of the goods) is regarded as a system unknown input in this study, so that the FDI decision is not disturbed by the...... system uncertainties relevant to this state dynamic and the original system disturbance $Q_{airload}$ (the thermal feature of the air). It has been observed that a single UIO has a very good detection capability for concerned sensor and parametric faults. However, only the parametric fault can be...... isolated by using a bank of UIOs. Thereby, a complete FDI approach is proposed by combining the Extended-Kalman-Filter (EKF) and UIO methods, after an extensive comparison of KF-, EKF- and UIO-based FDI methods is carried out.

    The aim of this study was to elucidate whether and to what extent fresh produce from Germany plays a role as a carrier and reservoir of antibiotic resistant bacteria. For this purpose, 1001 vegetables (fruit, root, bulbous vegetables, salads and cereals) were collected from 13 farms and 11 supermarkets in Germany and examined bacteriologically. Phenotypic resistance of Enterobacter cloacae (n=172); Enterobacter gergoviae (n=92); Pantoea agglomerans (n=96); Pseudomonas aeruginosa (n=295); Pseudomonas putida (n=106) and Enterococcus faecalis (n=100) against up to 30 antibiotics was determined by using the microdilution method. Resistance to ß-lactams was most frequently expressed by P. agglomerans and E. gergoviae against cefaclor (41% and 29%). Relatively high resistance rates were also observed for doxycycline (23%), erythromycin (21%) and rifampicin (65%) in E. faecalis, for spectinomycin (28%) and mezlocillin (12%) in E. cloacae, as well as for streptomycin (19%) in P. putida. In P. aeruginosa, relatively low resistance rates were observed for the aminoglycosides amikacin, apramicin, gentamicin, neomycin, netilmicin and tobramycin (<4%); 11% was resistant to streptomycin. No glycopeptide-resistant enterococci were observed. Resistance rates of bacteria isolated from farm samples were higher than those of the retail markets whenever significant differences were observed. This suggests that expressing resistance is at the expense of bacterial viability, since vegetables purchased directly at the farm are probably fresher than at the supermarket, and they have not been exposed to stress factors. However, this should not keep the customer from buying directly at the farm, since the overall resistance rates were not higher than observed in bacteria from human or animal origin. Instead, peeling or washing vegetables before eating them raw is highly recommended, since it reduces not only the risk of contact with pathogens, but also that of ingesting and spreading

    Objective: To determine the presence and levels of microbes in unexpired pasteurized milk from randomly selected supermarkets in Kingston, Jamaica. Methods: The quantitative study used a stratified random sampling technique in the selection of the 20 representative milk samples from six (6) supermarkets. Microbiological tests such as methylene blue reduction, standard plate count (SPC), coliform plate count (CPC), purity plate culture, gram staining and biochemical tests were performed to examine the microbes in purchased unexpired pasteurized milk. Results: One sample (BCr016) had a pH of 4.0, a rancid odour and curdled appearance. It decolourized within one hour during the methylene blue reduction test and was classified as class 4 milk. Seven of the samples were sterile with no microbe growth on the plate count agar and violet red bile salt agar (VRBA). The milk samples that appeared to be safe for consumption were all 10, 11, 12 and 13 days before expiration. The VRBA sample BCr016, had a colony count of 13 400 CFU/ mL. There was the presence of Escherichia coli in sample LCr021 which had a standard plate count of 1 580 SPC/mL and a coliform count of 500 CFU/mL. Enterobacter sp. was present in colonies from BCr016 and all the other milk samples. Conclusions: Unacceptable levels of Enterobacter spp. and Escherichiacoli were found in most of the samples. Effective measures to ensure safe milk for human consumption such as the phosphatase test and methylene blue reduction test should be routinely performed on each batch of milk processed by dairy plants.

En la lucha contra esta adicción, la existencia de una legislación eficaz para disminuir la producción, distribución y venta de productos derivados del tabaco es indispensable para crear las condiciones necesarias y lograr una sociedad libre de tabaco. La venta de cigarros a menores es un acto que posee características específicas en cada lugar y tiempo en que se evalúa. En particular, en el Distrito Federal la falta de vigilancia en el cumplimiento de las disposiciones oficiales contribuye a que los menores de edad consigan los cigarros en la mayoría de los comercios y los adquieran de forma directa.In Mexico and other countries, the accessibility that minors have to products derived from tobacco -mainly cigarettes- is a primary contributing factor to smoking, and is currently one of the main public health challenges worldwide.

    Buildings and urban construction are understood in this paper as representations of the city. Their meanings, however, are often invisible, positing unrealized urban visions, which are both imbedded in and which call up chains of associations expressing desires and fears. Narratives of what the city should be often contain the rejection of the existing urban situation. Understanding architectural objects as potential underscores their imaginary nature. Freud, for example, uses the Roman ruins...

  11. Sustainable cities

    International Nuclear Information System (INIS)

    The Sustainable City Project, a collaboration among the cities of Portland, Oregon, and San Francisco and San Jose, California, aims at developing and implementing sustainable energy planning methods and programs for cites. For a period of two years (1989-90), the three project cities worked in parallel, yet pursued independent courses to develop appropriate sustainable urban energy practices to meet local needs and aspirations. Central to the Sustainable City Project was finding ways to manage today's urban energy needs without jeopardizing the needs of future generations. Sustainability implies that nothing should go to waste, but rather should contribute to the proper balance between the natural environment and the built environment Sustainable urban energy systems encompass more than energy efficiency and energy conservation measures: they must be diverse, flexible, self-reliant, renewable, and integrated. Since local governments make decisions affecting land use, building codes, transportation systems, waste disposal, and power plants--all of which impact energy resource use--local jurisdictions can do much to ensure their own sustainable future. This paper will present an accounting of the specific steps that each city took to determine and begin implementation of their respective approaches to sustainable energy planning, with a specific focus on the City of San Jose activities. Useful tools for facilitating community process, program planning and implementation, and quantitative analysis will also be discussed

  12. From producer to consumer: greenhouse tomato quality as affected by variety, maturity stage at harvest, transport conditions, and supermarket storage.

    Verheul, Michèl J; Slimestad, Rune; Tjøstheim, Irene Holta

    2015-05-27

    Possible causes for differences in quality traits at the time of buying were studied in two widely different red tomato types. Three maturity stages were harvested from commercial greenhouses and transferred immediately to controlled environments simulating different storage, transport, and supermarket conditions. Results show significant differences in development of color, fruit firmness, contents of soluble solids (SSC), titratable acids (TTA), phenolics, and carotenoids from harvest to sale, as related to postharvest conditions. Fruit firmness, SSC, and TTA of vine-ripened red cherry tomatoes was 30, 55 and 11% higher than for those harvested at breakers and ripened to red. Temperature, light, UVC radiation, or ethylene during 4 days transport affected tomato quality traits, and differences persisted during 3 weeks of supermarket storage. Ethylene exposure gave a 3.7-fold increase in lycopene content in cherry tomatoes, whereas UVC hormesis revealed a 6-fold increase compared with the control. Results can be used to update recommendations concerning optimal handling. PMID:25916229

    Large retail chains have spent considerable resources to promote production protocols and traceability across the supply chain, aiming at increasing food safety. Yet, the majority of consumers are unaware of these private food safety standards (PFSS) and retailers are not informing them. This behavior denotes a pooling paradox: supermarkets spend a large amount of money for food safety and yet they forget to inform consumers. The result is a pooling equilibrium where consumers cannot discrimi...

  17. An analysis of the number of parking bays and checkout counters for a supermarket using SAS simulation studio

    Kar, Leow Soo

    2014-07-01

    Two important factors that influence customer satisfaction in large supermarkets or hypermarkets are adequate parking facilities and short waiting times at the checkout counters. This paper describes the simulation analysis of a large supermarket to determine the optimal levels of these two factors. SAS Simulation Studio is used to model a large supermarket in a shopping mall with car park facility. In order to make the simulation model more realistic, a number of complexities are introduced into the model. For example, arrival patterns of customers vary with the time of the day (morning, afternoon and evening) and with the day of the week (weekdays or weekends), the transport mode of arriving customers (by car or other means), the mode of payment (cash or credit card), customer shopping pattern (leisurely, normal, exact) or choice of checkout counters (normal or express). In this study, we focus on 2 important components of the simulation model, namely the parking area, the normal and express checkout counters. The parking area is modeled using a Resource Pool block where one resource unit represents one parking bay. A customer arriving by car seizes a unit of the resource from the Pool block (parks car) and only releases it when he exits the system. Cars arriving when the Resource Pool is empty (no more parking bays) leave without entering the system. The normal and express checkouts are represented by Server blocks with appropriate service time distributions. As a case study, a supermarket in a shopping mall with a limited number of parking bays in Bangsar was chosen for this research. Empirical data on arrival patterns, arrival modes, payment modes, shopping patterns, service times of the checkout counters were collected and analyzed to validate the model. Sensitivity analysis was also performed with different simulation scenarios to identify the parameters for the optimal number the parking spaces and checkout counters.

    2015-01-01

    Fifty strains of Campylobacter jejuni/coli were detected in 108 specimens of chicken meat and organs sampled at six supermarkets and one poultry slaughterhouse (large scale) between April and October 2013 (isolation rates: 84.8% from the slaughterhouse, 29.3% from the supermarkets). 46/50 strains were successfully recovered and subjected to the E-test to examine their susceptibility to three fluoroquinolone antibacterial agents authorized for use in poultry in Japan: enrofloxacin (ERFX), ofloxacin (OFLX), and norfloxacin (NLFX). 29 isolates (63%) were resistant to all three agents and 2 isolates (4.3%) were resistant to two agents (ERFX and OFLX). The resistance rates of strains isolated fom the supermarkets and slaughterhouse were 61.9% and 72.0%, respectively. Because the chickens processed at the slaughterhouse were raised without the use of fluoroquinolone, the results did not suggest a positive relationship between the use of these agents and the distribution of antimicrobial-resistant bacteria. Susceptibility to macrolide antibiotics (erythromycin [EM]) was also tested in 42 strains, and one strain (2.4%), C. coli from a retailer sample, showed resistance. Previous studies have detected high rates of fluoroquinolone-resistant strains, suggesting an expanding distribution of resistant bacteria. The detection of EM-resistant bacteria downstream in the food distribution chain (i.e., closer to consumers) is a concern for human health. PMID:26412697

    2015-08-01

    Full Text Available To address the possible limitations that financial restrictions may have on students’ independent experimentation at school, we developed and implemented an inexpensive approach for basic microbiology education. We describe four nutrient agars consisting only of everyday substances available from the supermarket or online that we developed to replace standard agars and specific agars. Additionally, we selected Bacillus subtilis natto as an example of a pure-culture species. Our tip first reports the four supermarket-substance agar variants; second, it suggests utilizing them to introduce basic microbiological techniques; and third, it introduces B. subtilis natto in the context of the antibacterial effects of antibiotics as well as of supermarket products which students can bring to class from home. We implemented our approach in microbiology education at school as well as in pre-service teacher education and in in-service teacher professional development courses at our university. Finally, our paper provides worksheets for all the experiments. Editor's Note:The ASM advocates that students must successfully demonstrate the ability to explain and practice safe laboratory techniques. For more information, read the laboratory safety section of the ASM Curriculum Recommendations: Introductory Course in Microbiology and the Guidelines for Biosafety in Teaching Laboratories, available at www.asm.org. The Editors of JMBE recommend that adopters of the protocols included in this article follow a minimum of Biosafety Level 1 practices. If the soil plates described in the activity are opened, a minimum of Biosafety Level 2 is required.

    2012-01-01

    Background. We investigated differences in family social class associations between food outlet exposure and fruit and vegetable intake. Methods. We supplemented data from the 2006 Health Behavior in School Aged Children Study (n = 6, 096) with geocoded food outlet information surrounding schools (n = 80). We used multilevel logistic regression to examine associations between infrequent fruit and vegetable intake and supermarket and fast food outlet concentration, stratified by family social class. Results. Boys and older children were most likely to eat fruit and vegetables infrequently. High fast food outlet exposure was marginally significant for low fruit intake in low social class children only. Children from middle and low social class backgrounds attending schools with combined high fast food outlet/low supermarket exposure were most likely to report infrequent fruit intake (ORlow = 1.60; CI:  1.02–2.45; ORmid = 1.40; CI:  1.03–190). Children from low social class backgrounds were also likely to report infrequent vegetable intake, given low supermarket and high fast food outlet exposure (OR = 1.79; CI:  0.99–3.21). Conclusion. Our findings suggest social class modifies the relationship between intake and food outlet concentration. School interventions improving fruit and vegetable intake should consider neighborhood surroundings, targetting older children from low social class backgrounds. PMID:22988491

    2016-03-01

    Childhood overweight and obesity rates in Canada are at concerning levels, more apparently so for individuals of lower socioeconomic status (SES). Accessibility to food establishments likely influences patterns of food consumption, a contributor to body weight. Previous work has found that households living in lower income neighbourhoods tend to have greater geographical accessibility to unhealthy food establishments and lower accessibility to healthy food stores. This study contributes to the literature on neighbourhood inequalities in accessibility to healthy foods by explicitly focusing on children, an understudied population, and by incorporating mobility and time into metrics of accessibility. Accessibility to both healthy and unhealthy food retailing is measured within children's activity spaces using Road Network and Activity Location Buffering methods. Weekday vs. weekend accessibility to food establishments is then compared. The results suggest that children attending lower SES schools had almost two times the density of fast food establishments and marginally higher supermarket densities in their activity spaces. Children attending higher SES schools also had much larger activity spaces. All children had higher supermarket densities during weekdays than on weekend days. PMID:26889950

    Here we sketch the rudiments of what constitutes a smart city which we define as a city in which ICT is merged with traditional infrastructures, coordinated and integrated using new digital technologies. We first sketch our vision defining seven goals which concern: developing a new understanding of urban problems; effective and feasible ways to coordinate urban technologies; models and methods for using urban data across spatial and temporal scales; developing new technologies for communication and dissemination; developing new forms of urban governance and organisation; defining critical problems relating to cities, transport, and energy; and identifying risk, uncertainty, and hazards in the smart city. To this, we add six research challenges: to relate the infrastructure of smart cities to their operational functioning and planning through management, control and optimisation; to explore the notion of the city as a laboratory for innovation; to provide portfolios of urban simulation which inform future designs; to develop technologies that ensure equity, fairness and realise a better quality of city life; to develop technologies that ensure informed participation and create shared knowledge for democratic city governance; and to ensure greater and more effective mobility and access to opportunities for urban populations. We begin by defining the state of the art, explaining the science of smart cities. We define six scenarios based on new cities badging themselves as smart, older cities regenerating themselves as smart, the development of science parks, tech cities, and technopoles focused on high technologies, the development of urban services using contemporary ICT, the use of ICT to develop new urban intelligence functions, and the development of online and mobile forms of participation. Seven project areas are then proposed: Integrated Databases for the Smart City, Sensing, Networking and the Impact of New Social Media, Modelling Network Performance

    2014-04-01

    Full Text Available Consumer reaction to food scares has been given considerable research attention but insights into specific shopper segments’ reactions to food scares, especially those that do not pose direct health risk to the public is limited. This paper examines how different life-stage shopper segments reacted to the horsemeat scandal in the UK. This paper draws on the analysis of supermarket loyalty card dataset of 1.7 million beef burger shoppers to establish the effect of the horsemeat scandal on retail sales value and volume as well as the rate of withdrawal of life-stage shopper segments from the affected products. The results show consistent weekly decline in retail sales value and volume across all life-stage segments over six consecutive weeks after the first horsemeat scandal announcement. Young families, pensioners and young adults segments withdrew from affected products in accordance with their typical perception and attitudes to risk. Contrary to expectation older adults withdrew faster than young families from the affected products. The findings of the study offer useful insights and strategic direction for managers working to ensure that food scares are managed to the benefit of the public and the food industry.

    The signing of the energy efficiency covenant by a large number of supermarkets has made the deployment of heat recovery in refrigeration quite common. Previous reports have mentioned the importance of aligning the various disciplines. Generally, the heat installer is unaware of the influence he has on the energy use of refrigeration. This article addresses several types of heat recovery that may be suitable for deployment, depending on the situation (new buildings, renovation, et cetera) [Dutch] Doordat een groot aantal supermarkten het convenant energiebesparing bij supermarkten hebben ondertekend is het toepassen van WTW op de koel- en vriesinstallatie nagenoeg gemeen goed geworden. In eerdere rapportages is reeds melding gemaakt van het belang van de afstemming tussen de verschillende disciplines. Over het algemeen kan gezegd worden dat de warmte-installateur zich niet bewust is welke invloed hij uitoefent op het energiegebruik van de koel- en vriesinstallatie. In dit artikel komen een aantal uitvoeringsvormen van WTW aan de orde die op dit moment afhankelijk van de situatie (nieuwbouw/renovatie, enz.) overwogen kunnen worden.

    From a large amount of records, one can extract behavioral characteristics of a social system at different scales. Theoretically, it can help us to know how the global behavior of a social system is formed from individual activities. Practically, it can be used to optimize and even to control the social system. Complicated relationships between the individuals form a network, which evolves with time. The behavior of the system can be accordingly understood in the framework of temporal network. In the present paper, instead of focusing on microscopic structures, we develop a framework to investigate temporal networks from the viewpoint of diffusion process, in which each snapshot network is divided into groups and the ID number of the group a node belongs to is used to measure its state. By this way trajectories of the nodes form an ensemble of realizations of a stochastic process. As an illustration, we investigate the diffusion behavior of a supermarket. One can find that with the increase of time the customers cluster and separate into different groups. Meanwhile, the system evolves in a significant order way, instead of a complete random one.

This has been implemented in an attempt to adapt to new consumer trends that have come to appreciate such initiatives in its product evaluation and to align with new legal obligations relating to environmental issues. It is is justified both for the supermarket retail industry and for the field of sustainability studies to examine the main factors influencing consumers to buy retail market consumer products considered "green." A survey was conducted with a sample of 174 students in postgraduate courses. The regression lines of each factor were evaluated according to the categorical variables: gender, family income, age group and marital status. The results show differences concerning gender and marital status. There are differences in the factor “reduction of environmental impacts” regarding the variables family income and age. This analysis indicates that the views of the sample is homogeneous (everyone pays attention to product information and there is an apparent concern with environmental issues and with the purchase of green products.DOI:10.5585/remark.v10i1.2213

    This research initiative CITY 2020+ assesses the risks and opportunities for residents in urban built environments under projected demographic and climate change for the year 2020 and beyond, using the City of Aachen as a case study. CITY 2020+ develops scenarios, options and tools for planning and developing sustainable future city structures. We investigate how urban environment, political structure and residential behavior can best be adapted, with attention to the interactions among structural, political, and sociological configurations and with their consequences on human health. Demographers project that in the EU-25-States by 2050, approximately 30% of the population will be over age 65. Also by 2050, average tem¬peratures are projected to rise by 1 to 2 K. Combined, Europe can expect enhanced thermal stress and higher levels of particulate matter. CITY 2020+ amongst other sub-projects includes research project dealing with (1) a micro-scale assessment of blockages to low-level cold-air drainage flow into the city centre by vegetation and building structures, (2) a detailed analysis of the change of probability density functions related to the occurrence of heat waves during summer and the spatial and temporal structure of the urban heat island (UHI) (3) a meso-scale analysis of particulate matter (PM) concentrations depending on topography, local meteorological conditions and synoptic-scale weather patterns. First results will be presented specifically from sub-projects related to vegetation barriers within cold air drainage, the assessment of the UHI and the temporal and spatial pattern of PM loadings in the city centre. The analysis of the cold air drainage flow is investigated in two consecutive years with a clearing of vegetation stands in the beginning of the second year early in 2010. The spatial pattern of the UHI and its possible enhancement by climate change is addressed employing a unique setup using GPS devices and temperature probes fixed to

    Over the last two years secondary coolant systems have found wide acceptance in supermarkets, especially in applications for food refrigeration. Compared to direct expansion systems the content of refrigerant in secondary coolant systems can be reduced dramatically. If the total equivalent warming impact (TEWI) is taken as a criterion for the environmental impact of such refrigeration systems one can observe that not anymore the refrigerant as such but the total consumption of energy is a significant contributor to pollution. Hence the efforts should be directed towards minimizing power consumption even considering common refrigerants rather than new, unestablished refrigerants. Reducing power consumption of such systems is possible only with electronic control of evaporators, variable coolant pumps, adequate heat reclaim concepts and demand control of condensing units. Investment costs of secondary coolant systems are slightly higher compared to DX-installations. These costs are nevertheless offset by lower maintenance and - with adequate control strategies in place - lower operating costs. (orig.)

Allerdings haben auch hier zahlreiche Firmen Anlagen auf der Basis von Kaeltetraegersystemen realisiert. Verglichen mit Direktverdampferanlagen kann in neuen, ideal konzipierten Systemen die Kaeltemittelfuellmenge um bis zu 85% reduziert werden. Wird der TEWI als Mass fuer die Umweltvertraeglichkeit angenommen, zeigt sich, dass aufgrund der stark reduzierten Kaeltemittelmenge nicht mehr die direkten Emissionen durch die Kaeltemittel von zentraler Bedeutung sind, sondern der absolute Energieverbrauch der Installation. Es zeigt sich auch, dass Kaeltetraegersysteme fuer die Pluskuehlung gleiche oder

    Between 2000 and 2005, 717 samples of three types of salads were analysed for Listeria monocytogenes in Santiago, Chile in order to provide information to Chilean health authorities on the presence of the pathogen in vegetable salad samples and to ascertain the risk of these products for consumers. L. monocytogenes isolates were found in 88 out of 347 (25.4%) samples of frozen vegetable salads and in 22 out of 216 (10.2%) freshly supermarkets prepared, cooked or raw ready-to-eat vegetable salads; no Listeria was isolated from 154 samples of raw minimally processed salads industrially prepared. Enumeration of L. monocytogenes was done by plate count for 20 positive frozen samples, randomly chosen. Most of them (90%) had or = 1100/g, five ranged between 240 and 93, eight between 23 and three and nine had contaminated frozen samples. Isolation of strains was done using three selective agars. Sixty-two L. monocytogenes were isolated from lithium chloride phenylethanol moxalactam agar, 95 from Listeria selective agar Oxford formulation, and 103 from polymixin acriflavine lithium chloride ceftazidime aesculin mannitol agar. Fifty isolates (45.5%) belong to PCR group IIb (including strains serovar 1/2b), 41 (37.3%) to PCR group IVb (including strains serovar 4b), 17 (15.5%) to PCR group IIa (including strains serovar 1/2a), and 2 (1.8%) to PCR group IIc. With the use of DNA macrorestriction patterns analysis, 17 different clusters were detected among 71 isolates, with P10, the most frequent with 25 isolates (35.2%) of PCR group IIb. PMID:19410317

      The supermarket and convenience store business model is commonly used in retail enterprises. For convenience, we choose the supermarket as the research object, to study the inventor control theory in the supermarket management inventory application. To ensure the normal operating activities, the supermarket needs some inventories. So the inventory management became an essential question for the distribution center of supermarket. And reasonable inventory ensures the supply and demand of supermarket management. Taking the speed up of the capital into consideration, reduce the capital takes up on the inventory, and makes every efforts to keep inventory form the reasonable proportion between relations, so as to further make the cost of inventory minimum. However, make inventory strategies for all the goods-stored needs a lot of time and money, this is obviously not advisable in the actual economic. There to study on financial management, select several typical articles for the resident daily use which are being the representatives on the storage solution for work.

    In Mexico, maize tortillas are consumed on a daily basis, leading to possible aflatoxin exposure. In a survey of 396 2-kg samples, taken over four sampling days in 2006 and 2007 from tortilla shops and supermarkets in Mexico City, aflatoxin levels were quantified by HPLC. In Mexico, the regulatory limit is 12 µg kg⁻¹ total aflatoxins for maize tortillas. In this survey, 17% of tortillas contained aflatoxins at levels of 3-385 µg kg⁻¹ or values below the limit of quantification (12 µg kg⁻¹ and 87% were below the regulatory limit. Average aflatoxin concentrations in 56 contaminated samples were: AFB1 (12.1 µg kg⁻¹); AFB2 (2.7 µg kg⁻¹); AFG1 (64.1 µg kg⁻¹) and AFG2 (3.7 µg kg⁻¹), and total AF (20.3 µg kg⁻¹). PMID:24779661

    We studied non-cancer mortality in 10,701 workers in the meat and delicatessen departments of supermarkets because they have increased exposure to a variety of microorganisms that infect and cause disease in food animals such as cattle, pigs, sheep, and poultry, to which subjects in the general population are also exposed, albeit to a lesser degree. These workers were also exposed to fumes from the wrapping machine. Standardized mortality ratios were estimated in the cohort as a whole and in race/sex subgroups, using the US population for comparison. Study subjects were followed up from January 1950 to December 2006. Significantly increased deaths from diabetes, ischemic heart disease, pulmonary embolism, chronic bronchitis, peritonitis, intracranial and intraspinal abscess, other bacterial diseases, and significantly decreased deaths from diffuse diseases of connective tissue, functional diseases of the heart, intracerebral hemorrhage, occlusion/stenosis of the precerebral and cerebral arteries, and various types of accidents were observed in certain race/sex subgroups or in the cohort as a whole. The observed increased risks of several infectious conditions suggest that the increased occupational exposure to microorganisms may be responsible for at least some of the observed excess deaths, while exposure to fumes may also contribute to the excess of chronic bronchitis. The findings are important not only for supermarket workers and other workers in the meat and poultry industries, but also because the general population is exposed to these microorganisms found in food animals and their products. Nested case-control studies within cohorts that include both workers in supermarkets and other sectors of the meat and poultry industries, are now needed to examine specific risks from occupational exposures while adequately controlling for confounding factors, so that the role of these infectious agents in the occurrence of these diseases in workers and in general

    Many urban phenomena exhibit remarkable regularity in the form of nonlinear scaling behaviors, but their implications on a system of networked cities has never been investigated. Such knowledge is crucial for our ability to harness the complexity of urban processes to further sustainability science. In this paper, we develop a dynamical modeling framework that embeds population-resource dynamics-a generalized Lotka-Volterra system with modifications to incorporate the urban scaling behaviors-in complex networks in which cities may be linked to the resources of other cities and people may migrate in pursuit of higher welfare. We find that isolated cities (i.e., no migration) are susceptible to collapse if they do not have access to adequate resources. Links to other cities may help cities that would otherwise collapse due to insufficient resources. The effects of inter-city links, however, can vary due to the interplay between the nonlinear scaling behaviors and network structure. The long-term population level of a city is, in many settings, largely a function of the city's access to resources over which the city has little or no competition. Nonetheless, careful investigation of dynamics is required to gain mechanistic understanding of a particular city-resource network because cities and resources may collapse and the scaling behaviors may influence the effects of inter-city links, thereby distorting what topological metrics really measure.

  11. 'It's risky to walk in the city with syringes': understanding access to HIV/AIDS services for injecting drug users in the former Soviet Union countries of Ukraine and Kyrgyzstan

    LENUS (Irish Health Repository)

    Spicer, Neil

    2011-07-13

    Abstract Background Despite massive scale up of funds from global health initiatives including the Global Fund to Fight AIDS, Tuberculosis and Malaria (Global Fund) and other donors, the ambitious target agreed by G8 leaders in 2005 in Gleneagles to achieve universal access to HIV\\/AIDS treatment by 2010 has not been reached. Significant barriers to access remain in former Soviet Union (FSU) countries, a region now recognised as a priority area by policymakers. There have been few empirical studies of access to HIV\\/AIDS services in FSU countries, resulting in limited understanding and implementation of accessible HIV\\/AIDS interventions. This paper explores the multiple access barriers to HIV\\/AIDS services experienced by a key risk group-injecting drug users (IDUs). Methods Semi-structured interviews were conducted in two FSU countries-Ukraine and Kyrgyzstan-with clients receiving Global Fund-supported services (Ukraine n = 118, Kyrgyzstan n = 84), service providers (Ukraine n = 138, Kyrgyzstan n = 58) and a purposive sample of national and subnational stakeholders (Ukraine n = 135, Kyrgyzstan n = 86). Systematic thematic analysis of these qualitative data was conducted by country teams, and a comparative synthesis of findings undertaken by the authors. Results Stigmatisation of HIV\\/AIDS and drug use was an important barrier to IDUs accessing HIV\\/AIDS services in both countries. Other connected barriers included: criminalisation of drug use; discriminatory practices among government service providers; limited knowledge of HIV\\/AIDS, services and entitlements; shortages of commodities and human resources; and organisational, economic and geographical barriers. Conclusions Approaches to thinking about universal access frequently assume increased availability of services means increased accessibility of services. Our study demonstrates that while there is greater availability of HIV\\/AIDS services in Ukraine and Kyrgyzstan, this does not equate with

Differences in availability of foods may have an important influence on individual eating behaviors and health disparities. This study examined the availability of food stores and food service places by city characteristics on city level of income and urbanization.The cross-sectional survey was comprised of two parts: (1 an on-site observation to measure availability of food stores and food service places in 12 cities of China; (2 an in-store survey to determine the presence of fresh/frozen vegetables or fruits in all food stores. Trained investigators walked all the streets/roads within study tracts to identify all the food outlets. An observational survey questionnaire was used in all food stores to determine the presence of fresh/frozen vegetables or fruits. Urbanization index was determined for each city using a principal components factor analysis. City level of income and urbanization and numbers of each type of food stores and food service places were examined using negative binomial regression models.Large-sized supermarkets and specialty retailers had higher number of fresh/frozen vegetables or fruits sold compared to small/medium-sized markets. High-income versus low-income, high urbanized versus low urbanized areas had significantly more large-sized supermarkets and fewer small/medium-sized markets. In terms of restaurants, high urbanized cities had more western fast food restaurants and no statistically significant difference in the relative availability of any type of restaurants was found between high- and low-income areas.The findings suggested food environment disparities did exist in different cities of China.

    2012-12-01

    Full Text Available Purpose: Post Apartheid, the South African supermarket industry has rapidly increased in size and stature, yet customer satisfaction and fostering goodwill don't appear to have kept pace with growth. This research considers which aspects of retail service quality impact upon customer satisfaction and, ultimately, pay dividends in terms of generating store loyalty amongst urban shoppers in the middle to upper market segments. Design/methodology/approach: A survey approach was used to collect data from 307 respondents within a major metro pole area, as well as through an online interface. This was used to test our path model using Partial Least Squares (PLS analysis. Findings: The results from the analysis concluded that two constructs, namely Physical Aspects and Personal Interaction, had a direct relationship with Customer Satisfaction. Customer satisfaction was also confirmed to be positively linked to customer loyalty. Originality/Value: This research uncovers which aspects of service are most coveted by consumers in an emerging market context, as well as their effect on generating repeat business. If supermarket chains are to move beyond mere profit generation and build meaningful relationships with customers, they would best be advised to focus on the attributes of service that have a direct bearing on customer satisfaction and, in turn, long-term repeat patronage.

  15. Field measurements of supermarket refrigeration systems. Part I: Analysis of CO2 trans-critical refrigeration systems

    International Nuclear Information System (INIS)

    This study investigates the refrigeration performance of three CO2 trans-critical solutions based on field measurements. The measurements are carried out in five supermarkets in Sweden. Using the field measurements, low and medium temperature level cooling capacities and COP's are calculated for ten-minute intervals, filtered and averaged to monthly values. The results indicate that the systems using trans-critical booster system with gas removal from the intermediate vessel have relatively the highest total COP. The reasons are higher evaporation temperatures, lower internal and external superheat and higher total efficiency of booster compressors. Another important factor is gas removal from the intermediate vessel which leads to higher COP of low temperature level. Comparing the older and newer installed systems, a trend in energy efficiency improvement has been seen. The study shows this improvement originates from both changes in the system design (e.g. two stage expansion) and components efficiency improvement (e.g. higher total efficiency of compressors - lower internal superheat and higher evaporation temperatures of cabinets). - Highlights: • Five Swedish supermarkets using three CO2 refrigeration solutions are analyzed. • A trend of improvement in energy efficiency has been observed. • Parallel CO2 system with indirect heat rejection offers the lowest energy efficiency. • CO2 trans-critical booster with gas removal achieves up to 35% COP improvement

    Despite tremendous growth in the consumption of gluten-free (GF) foods, there is a lack of evaluation of their nutritional profile and how they compare with non-GF foods. The present study evaluated the nutritional quality of GF and non-GF foods in core food groups, and a wide range of discretionary products in Australian supermarkets. Nutritional information on the Nutrition Information Panel was systematically obtained from all packaged foods at four large supermarkets in Sydney, Australia in 2013. Food products were classified as GF if a GF declaration appeared anywhere on the product packaging, or non-GF if they contained gluten, wheat, rye, triticale, barley, oats or spelt. The primary outcome was the 'Health Star Rating' (HSR: lowest score 0.5; optimal score 5), a nutrient profiling scheme endorsed by the Australian Government. Differences in the content of individual nutrients were explored in secondary analyses. A total of 3213 food products across ten food categories were included. On average, GF plain dry pasta scored nearly 0.5 stars less (Pgluten intolerance. PMID:26119206

    2012-06-01

    Full Text Available Abstract Background In recent years supermarkets and fast food restaurants have been replacing those “wet markets” of independent vendors as the major food sources in urban China. Yet how these food outlets relate to children’s nutritional intake remains largely unexplored. Method Using a longitudinal survey of households and communities in China, this study examines the effect of the urban built food environment (density of wet markets, density of supermarkets, and density of fast food restaurants on children’s nutritional intake (daily caloric intake, daily carbohydrate intake, daily protein intake, and daily fat intake. Children aged 6–18 (n = 185 living in cities were followed from 2004 to 2006, and difference-in-difference models are used to address the potential issue of omitted variable bias. Results Results suggest that the density of wet markets, rather than that of supermarkets, positively predicts children’s four dimensions of nutritional intake. In the caloric intake model and the fat intake model, the positive effect of neighborhood wet market density on children’s nutritional intake is stronger with children from households of lower income. Conclusion With their cheaper prices and/or fresher food supply, wet markets are likely to contribute a substantial amount of nutritional intake for children living nearby, especially those in households with lower socioeconomic status. For health officials and urban planners, this study signals a sign of warning as wet markets are disappearing from urban China’s food environment.

    Capon, Anthony G

    During 2007, the human species became predominantly urban. Australia is highly urbanised, and health varies within Australian cities. Australian urban life is characterised by sedentariness, excess food intake, reliance on cars for transport, a high level of exposure to media and marketing messages, and a consumer culture. These characteristics are linked to obesity, diabetes, heart disease, some cancers, chronic respiratory disease, injury, depression and anxiety. The evolution of cities has been characterised as a four-stage process: poverty, industrial, consumption and eco-city. Each stage but the last has defining health disorders. Transition to healthy and sustainable cities requires infrastructure investment in new urban areas (including mass transit, education and health services), better conditions for walking and cycling, access to healthy food and encouragement of suburban economic development. There is a role for everyone in the transition to healthy and sustainable cities. PMID:18072910

  9. Environmental issues of an intermediate city

    International Nuclear Information System (INIS)

    Our urban centers present a unique dimension of environmental problems. They are at one and the same time, enormous consumers of natural resources and produces of waste and pollution. In this respect intermediate cities and small towns appear to be more vulnerable to natural catastrophes and ecological accidents caused by human factors. While in large cities there exist pressure groups which attain government attention for the solution of their problems and have well equipped municipalities. However, a vast majority of the population lives in rural areas and depends upon medium sized cities and towns for access to services. These cities and towns form the pivot of economic, social, cultural and political life for a large part of the population. Therefore, it deserves more attention than bigger ones. This paper explores local people perception about urban environmental problems exist in the city. Attempts are also made to shape and guide municipality efforts to overcome such problems with available resources. (author)

The development make national boundary become not so important, the function of the city is increasingly outstanding. In other words, national competition ability is morally now on the city competition ability. At the same time, this development result that the industry is divided internationally and is divided in cities. Therefore, under the condition of globalization, if the city wants the superior development, it must take advantages and avoid shortage, to position the city accurately, establish the competition and development the strategy. The city positioning is clearly defined the city competition ability, more important it indicated the direction of the city development. Trough the analysis of the resource and environment of the city, decide an accurate position of the best function of the city, well configure the inner and outside resource, catch the opportunities,face the challenges, maximized the market share in order to maximized the wealth and city competition ability.

  16. Mercury in fish available in supermarkets in Illinois: Are there regional differences

    International Nuclear Information System (INIS)

    Media coverage has made the public aware of both the benefits and the risks from eating self-caught fish, but information on contaminants in commercial fish is much more limited, especially on a local level. The U.S. Food and Drug Administration website provides methylmercury data for a variety of fish, but for many species sample sizes are small and data are more than a decade old, whereas commercial fish sources are highly dynamic. A few state agencies are beginning to provide contaminant information for commercial fish, including canned tuna. We examined the mercury concentration of six types of fish purchased in supermarkets in Chicago, Illinois in 2005. We measured total mercury (methylmercury accounts for about 90% of the total mercury in fish). One key question was whether the concentrations of mercury in fish available locally were similar to those reported in other areas of the country and in the FDA U.S. national data base. Such information is critical for the public, especially pregnant women or those planning on pregnancy, making decisions about types and quantities of fish to consume. Some fish are available generally throughout the U.S., but others are more locally available, suggesting a need for site-specific information. This research was stakeholder driven, and reflected local interest in the safety of local fish. There were significant differences in mercury concentrations among the fish, ranging from a mean of 0.03 μg/g (ppm-wet weight) for salmon (Salmo spp.) to 1.41 ppm for swordfish (Xiphias gladius). Maximum values for three species of fish (orange roughy Hoplostethus atianticus, swordfish walleye Sander vitreus) were over 1 ppm (FDA action level), and all of the fish except salmon had some values above 0.5 ppm, the action level set by some states and countries. There were significant differences in mercury concentrations among three types of canned tuna (Thunnus spp): 'gourmet tuna' had the least amount of mercury, and white tuna had the

    Although serious efforts are made internationally and nationally, it is a slow process to make our physical environment accessible. In the actual design process, architects play a major role. But what kinds of knowledge, including research-based knowledge, do practicing architects make use of when...... designing accessible environments? The answer to the question is crucially important since it affects how knowledge is distributed and how accessibility can be ensured. In order to get first-hand knowledge about the design process and the sources from which they gain knowledge, 11 qualitative interviews...... were conducted with architects with experience of designing for accessibility. The analysis draws on two theoretical distinctions. The first is research-based knowledge versus knowledge used by architects. The second is context-independent knowledge versus context-dependent knowledge. The practitioners...

  1. Averaging over fast variables in the fluid limit for Markov chains: application to the supermarket model with memory

    CERN Document Server

    Luczak, M J

    2010-01-01

    We set out a general procedure which allows the approximation of certain Markov chains by the solutions of differential equations. The chains considered have some components which oscillate rapidly and randomly, while others are close to deterministic. The limiting dynamics are obtained by averaging the drift of the latter with respect to a local equilibrium distribution of the former. Some general estimates are proved under a uniform mixing condition on the fast variable which give explicit error probabilities for the fluid approximation. Mitzenmacher, Prabhakar and Shah \\cite{MPS} introduced a variant with memory of the `join the shortest queue' or `supermarket' model, and obtained a limit picture for the case of a stable system in which the number of queues and the total arrival rate are large. In this limit, the empirical distribution of queue sizes satisfies a differential equation, while the memory of the system oscillates rapidly and randomly. We illustrate our general fluid limit estimate in giving a ...

    Full Text Available This paper examines the impact of simulation, hyperreality, and consumerism on Don Delillo's novel "White Noise". It discusses how the novel pictures technology and mass media as an empire of signs and codes that erase or implode meaning. TV, radio reports and tidbits, and medical imaging devices are intertwined with many aspects of people's lives in this late capitalist culture. Futhermore, the paper will shed some light on the issue of hyperreality which is generated by simulations. We will see how this new type of reality becomes more real than reality itself. Then, the influence of the supermarket and the emergence of consumer culture will be discussed. We will see how production and consumption have gained a new different meaning in this new "superficial" society and how it reshapes people's undestanding and interaction with reality.

    The Internet lets us share perfect copies of our work with a worldwide audience at virtually no cost. We take advantage of this revolutionary opportunity when we make our work "open access": digital, online, free of charge, and free of most copyright and licensing restrictions. Open access is made possible by the Internet and copyright-holder consent, and many authors, musicians, filmmakers, and other creators who depend on royalties are understandably unwilling to give their consent. But for 350 years, scholars have written peer-reviewed journal articles for impact, not for money, and are free to consent to open access without losing revenue. In this concise introduction, Peter Suber tells us what open access is and isn't, how it benefits authors and readers of research, how we pay for it, how it avoids copyright problems, how it has moved from the periphery to the mainstream, and what its future may hold. Distilling a decade of Suber's influential writing and thinking about open access, this is the indispe...

  6. Water for cities

    International Nuclear Information System (INIS)

    Africa has entered the new Millennium with a sense of hope and renewed confidence. With widening and deepening of political reforms, economic liberalization and a strengthened civil society, an increasing number of African countries are striving towards economic recovery and sustainable development. But also Africa is a continent of paradox. Home to the world's longest river, the Nile, and the second largest freshwater lake, Lake Victoria. Africa has abundant water resources contributed by large rivers, vast stretches of wetlands and limited, but widely spread, groundwater. Yet only a limited number of countries are beneficiaries of this abundance. Fourteen African countries account for 80% of the total water available on the continent, while 12 of the countries together account for only 1% of water availability. Some 400 million people are estimated to be living in water-scarce condition today. Indeed my home country, Tanzania, claims over 40% of Africa's water resources from Lake Victoria, Lake Tanganaika and other major water bodies. Water in Africa is not only unfairly distributed by nature but, due to backward technology and underdevelopment, it remains also inadequately allocated by man. At the turn of the new Millennium, over 300 million people in Africa still do not have access to safe water. But perhaps nowhere is the challenge more complex and demanding than in the rapidly growing African cities. With an average growth rate of 5% per annum, Africa is the fastest urbanizing region in the world today. Between 1990 and 2020, in many of our life times, urban populations in Africa will rise fourfold from 138 to 500 million. The 'Water for African Cities Programme' is demonstrating, in seven African countries (Cote d'Ivoire, Ethiopia, Ghana, Kenya, Senegal, South Africa and Zambia), how to put in place an integrated urban water resource management strategy that could bring three key sectors -- urban, environment and water -- to work together.

Realizou-se um inquérito com 2.539 indivíduos de idade acima de 15 anos em 952 domicílios. As principais variáveis analisadas foram a necessidade de saúde bucal percebida, a procura pelo serviço, a barreira de acesso organizacional e o tipo de serviço e o procedimento utilizado. A utilização de serviços públicos odontológicos especializados foi de 11,7% e básicos de 26%. No município com maior utilização de serviços públicos odontológicos, foi menor o uso de serviços privados. A principal barreira de acesso situou-se na AP (Atenção Primária, entre 5,0% e 15,2%. Observou-se pouca interface da atenção secundária com a AP já que apenas 16,6% dos usuários retornaram a esse nível de atenção. Pode-se concluir que a principal barreira de acesso, em municípios com realidades organizacionais e geográficas específicas parece se situar na AP. Ações preventivas individuais foram pouco relatadas.

The paper will reflect about this process at a number of different spatial and temporal scales based on a conceptual model. Looking back at European history, it will trace the interaction between Christaller's logic of local market areas and the idea of (low contact cost network cities. Focusing on Switzerland since 1950 it will show how network investment changed the relative distribution of population and employment and how this interacted with changes in the preferences of the travelers. Using a recent snapshot of how a substantial sample of Swiss maintain their social networks over often very large areas, it will try to answer the question of what will happen in the future, if the current trend of ever lower costs of contact will persist.

    Full Text Available Com o objetivo de analisar a implantação de ações voltadas para a acessibilidade à atenção básica em um município da Bahia, Brasil, foi realizado estudo de caso único a partir de dois níveis de análise: organização do sistema e dos serviços. Os dados foram obtidos por intermédio de entrevistas semi-estruturadas, da observação das rotinas de atendimento e da análise documental. Das quatro unidades analisadas, três apresentaram nível intermediário de implantação de ações voltadas para a acessibilidade. As unidades de saúde da família tiveram melhor desempenho devido à presença de ações voltadas para o acolhimento e a referência a serviços especializados, porém apresentaram problemas para a marcação de consultas. Apesar do estabelecimento da atenção básica como porta de entrada ao sistema e da implantação da central de marcação de consultas especializadas, persistem barreiras organizacionais no município estudado. Recomenda-se a formulação de política específica para melhoria da acessibilidade voltada para a organização da oferta na perspectiva de mudança do modelo assistencial.In order to analyze the implementation of measures targeting accessibility to primary health care in a municipality (county in the State of Bahia, Brazil, a single case study was performed with two levels of analysis: system and services organization. The data were obtained from semi-structured interviews, observation of routine care, and document analysis. Of the four health units analyzed, three showed intermediate-level implementation of measures targeting accessibility. The Family Health Units showed better performance, due to measures for patient reception and referral to specialized services, but they revealed problems with scheduling of appointments. Despite having defined primary care as the portal of entry into the system and the implementation of a help desk for setting appointments with specialists, there are

    If one ranks cities by population, the rank of a city is inversely related to its size, a well-documented phenomenon known as Zipf's Law. Further, the growth rate of a city's population is uncorrelated with its size, another well-known characteristic known as Gibrat's Law. In this paper, I show that both characteristics are true of countries as well as cities; the size distributions of cities and countries are similar. But theories that explain the size-distribution of cities do not obviously...

  17. Toward a typology of sustainability for cities

    2014-06-01

    Full Text Available Sustainability responses must accelerate to avoid major risks to cities. Climate change impact on cities, likely to be significant if global sustainability initiatives are not quickened, is a paramount example of the risk. World wide meetings of city planning practitioners and researchers agree that an urgent agenda is to work together to empower cities and their governments with funds, tools and mentoring to make the responses needed. In the spirit of this urgent agenda, this paper introduces some practical methods for assessing sustainability associated with transport and urban form in our cities. A concept of strategic scans of future scenarios, which underpins the backcasting approach, has been introduced at the 12 th World Conference on Transport Research (WCTR in 2010 and has broken urban and transport planning trend. These strategic scans are based on a sustainability framework, the elements of which provide evidence based drivers of sustainability. The framework culminates in metric visualisations for each of the three pillars of sustainability. The paper details some of the operational aspects of these metrics in the form of environmental sustainability-accessibility space, putting into practice measures of environmental stewardship, social equity, economic efficiency, and the relationship among them. The paper concludes with a call of developing a typology of sustainability performance using the strategic scan methodology to extend the principles of the methodology into a useful tool for city governments and contribute to assembling a daTablease of city forms, transport structures, and their sustainability performances.

    The use of price promotions for fast moving consumer goods (FMCG’s) by supermarkets has increased substantially over the last decade, with significant implications for all stakeholders (suppliers, service providers & retailers) in terms of profitability and waste. The overall impact of price promotions depends on the complex interplay of demand and supply side factors, which has received limited attention in the academic literature. There is anecdotal evidence that in many cases, and particul...

Data were collected through 62 semi-structured interviews with people who declared themselves black or mulatto and visited the Testing and Counseling Center (TCC to take the HIV test. Data analysis was based on the premises of the Collective Subject Discourse. Most interviewees did not report any difficulties to get access to the HIV test. The repressed demand at the TCC was identified as a barrier, due to the limited test offer caused by material and human resource issues. No statement was found that demonstrated color/race discrimination during contact with the service. Factors appointed as facilitating test access included: free test, indication or referral by health professionals or service, access to the test site, service credibility, rapid care and absence of bureaucracy.

    Population explosion is considered to be one of the most crucial problems in the world. However, in Japan, the opposite problem: population decline has become serious now. Japanese population is estimated to decrease by twenty millions in 2040. This negative situation will cause to increase areas where many residents cannot make a daily living all over Japan because many convenience living facilities such as supermarkets, convenience stores and drugstores will be difficult to maintain their market area population due to future population decline. In our research, we used point data of convenience living facilities developed by address geocoding of digital telephone directory and point data of future population projection developed by distribution of Japanese official population projection data proportionally among the building volume of digital residential map, which can monitor building volumes all over Japan. In conclusion, we estimated that various convenience living facilities in Japan will shrink and close by population decline in near future. In particular, it is cleared that approximately 14.7% of supermarkets will be possible to withdraw all over Japan by 2040. In addition, it is cleared that over 40% of supermarkets in some countryside prefectures will be possible to withdraw by 2040. Thus, we estimated future distributions of convenience living facilities that cannot maintain their market area population due to future population decline. Moreover, we estimated the number of people that they will become inconvenience in buying fresh foods.

    This paper shows that Zipf's Law for cities can emerge as a property of a clustering process. If initially uniformly distributed people chose their location based on a specific gravity equation as found in trade studies, they will form cities that follow Zipf's Law in expected value. This view of cities as spatial agglomerations is supported empirically by the observation that larger cities are surrounded by larger hinterland areas and larger countryside populations.

    2012-02-01

    Full Text Available Abstract Background Lowering the price of fruit and vegetables is a promising strategy in stimulating the purchase of those foods. However, the true effects of this strategy are not well studied and it is unclear how the money saved is spent. The aim of this study is to examine the effects of a 25% discount on fruits and vegetables on food purchases in a supermarket environment. Methods A randomized controlled trial with two research conditions was conducted: a control condition with regular prices (n = 52 and an experimental condition with a 25% discount on fruits and vegetables (n = 63. The experiment was carried out using a three-dimensional web-based supermarket, which is a software application in the image of a real supermarket. Data were collected in 2010 in the Netherlands. Participants received a fixed budget and were asked to buy weekly household groceries at the web-based supermarket. Differences in fruit and vegetable purchases, differences in expenditures in other food categories and differences in total calories were analyzed using independent samples t-tests and multiple linear regression models accounting for potential effect modifiers and confounders. Results The purchased amount of fruit plus vegetables was significantly higher in the experimental condition compared to the control condition (Δ984 g per household per week, p = .03 after appropriate adjustments. This corresponds to a 25% difference compared to the control group. Both groups had similar expenditures in unhealthier food categories, including desserts, soda, crisps, candy and chocolate. Furthermore, both groups purchased an equal number of food items and an equal amount of calories, indicating that participants in the discount condition did not spend the money they saved from the discounts on other foods than fruits and vegetables. Conclusion A 25% discount on fruits and vegetables was effective in stimulating purchases of those products and did neither lead to

    2015-04-01

    Separate collection centres (SCCs), where citizens can deliver recyclable fractions of municipal solid waste (MSW), in an "urban mining" perspective, can be considered a sort of "reverse supermarket", where people can deliver their recyclables in order to either obtain a waste fee reduction or shopping vouchers. The latter is the case of Baronissi, a town of around 17,000 inhabitants in the Province of Salerno, in the Campania region of Italy. The principal aim of the study was to investigate by means of a sociological survey the relationship between citizens and the separate collection program, with particular emphasis on the role played by the SCC. The separate collection system was evaluated either good or very good by 95.8% of the sample, while 99.2% expressed a good or very good evaluation of the quality of the service inside the separate collection centre: SCC users acted as a community as highlighted by the negative response of the Chi-square test for independence. Respecting the environment prevailed over saving time, obtaining eco-points, or saving money as the main reason why people went to the SCC. The majority of the respondents agreed if only putrescibles and residue should be collected directly from their homes, while all the other materials should be collected exclusively at the SCC, allowing to save money for the management of the kerbside collection system with a consequent further waste fee reduction for the residents.

    Full Text Available Taking into consideration the financial criteria such as profitability, growth, sales volume and market share, don’t seem enough in evaluating the financial performance of a business. Because, these criteria are mainly related to the past performance of a business. For an evaluation directed for the future different factors other than the financial ones, which are also effective on financial success must be taken into consideration. The level of customer satisfaction and job satisfaction of the employees, which are effective in the financial performance of a firm in the future, is effective on the financial performance of a firm directly or indirectly in different levels. The aim of this study is testing the relation between “employee satisfaction and customer satisfaction” and to research the effect of both on the financial success of supermarkets, which are mainly service businesses. The research findings show that “the mediating effect of customer satisfaction between employee satisfaction and financial performance is strong”.

    2016-05-01

    Public health research has increasingly focused on how access to resources affects health behaviors. Mapping environmental factors, such as distance to a supermarket, can identify intervention points toward improving food access in low-income and minority communities. However, the existing literature provides little guidance on choosing the most appropriate measures of spatial access. This study compared the results of different measures of spatial access to large food stores and the locations of high and low access identified by each. The data set included U.S. Census population data and the locations of large food stores in the six-county area around Chicago, Illinois. Six measures of spatial access were calculated at the census block group level and the results compared. The analysis found that there was little agreement in the identified locations of high or low access between measures. This study illustrates the importance of considering the access measure used when conducting research, interpreting results, or comparing studies. Future research should explore the correlation of different measures with health behaviors and health outcomes. PMID:26494034

    There is a strong connection between economic growth and development of cities. Economic growth tends to stimulate city growth, and city economies have often shaped innovative environments that in turn support economic growth. Simultaneously, social and environmental problems related to city growth...... can be serious threats to the realization of the socio-economic contributions that cities can make. However, as a result of considerable diversity of competences combined with interactive learning and innovation, cities may also solve these problems.

Addressing this issue, the article draws an analogy between a human person and a city. Like a city, a human being needs to comprehend his self-identity in order to resist depressive tendencies. It is shown that a person’s depressive symptoms are similar to those of cities. The city identity necessary to resist depression can be searched for both historically and geographically. The historical aspect consists of local myths and legends about the city and the citizens. The geographical aspect of identity comprises features of the terrain, climate, flora and fauna of the region where the city is located.

  1. Biophilic Cities Are Sustainable, Resilient Cities

    2013-08-01

    Full Text Available There is a growing recognition of the need for daily contact with nature, to live happy, productive, meaningful lives. Recent attention to biophilic design among architects and designers acknowledges this power of nature. However, in an increasingly urban planet, more attention needs to be aimed at the urban scales, at planning for and moving towards what the authors call “biophilic cities”. Biophilic cities are cities that provide close and daily contact with nature, nearby nature, but also seek to foster an awareness of and caring for this nature. Biophilic cities, it is argued here, are also sustainable and resilient cities. Achieving the conditions of a biophilic city will go far in helping to foster social and landscape resilience, in the face of climate change, natural disasters and economic uncertainty and various other shocks that cities will face in the future. The paper identifies key pathways by which biophilic urbanism enhances resilience, and while some are well-established relationships, others are more tentative and suggest future research and testing.

    We study the optimal and equilibrium size of cities in a monocentric city model with environmental pollution. Pollution is related to city size through the effect of population on production, commuting, and housing consumption. If pollution is local, we find that equilibrium cities are too large, mirroring standard results in the theory of city systems. When pollution is global and per capita pollution declines with city size, however, equilibrium cities may be too small.

    Full Text Available Progressive cities worldwide have demonstrated political leadership by initiating meaningful strategies and actions to tackle climate change. However, the lack of knowledge concerning embodied greenhouse gas (GHG emissions of cities has hampered effective mitigation. We analyse trans-boundary GHG emission transfers between five Australian cities and their trading partners, with embodied emission flows broken down into major economic sectors. We examine intercity carbon footprint (CF networks and disclose a hierarchy of responsibility for emissions between cities and regions. Allocations of emissions to households, businesses and government and the carbon efficiency of expenditure have been analysed to inform mitigation policies. Our findings indicate that final demand in the five largest cities in Australia accounts for more than half of the nation’s CF. City households are responsible for about two thirds of the cities’ CFs; the rest can be attributed to government and business consumption and investment. The city network flows highlight that over half of emissions embodied in imports (EEI to the five cities occur overseas. However, a hierarchy of GHG emissions reveals that overseas regions also outsource emissions to Australian cities such as Perth. We finally discuss the implications of our findings on carbon neutrality, low-carbon city concepts and strategies and allocation of subnational GHG responsibility.

    The dynamics of transportation through towns and cities is strongly affected by the topology of the connections and routes. The current work describes an approach combining complex networks and self-avoiding random walk dynamics in order to quantify in objective and accurate manner, along a range of spatial scales, the accessibility of places in towns and cities. The transition probabilities are estimated for several lengths of the walks and used to calculate the outward accessibility of each node. The potential of the methodology is illustrated with respect to the characterization and improvements of the accessibility of the town of Sao Carlos.

  5. Use of Irradiation to Ensure Microbial Safety of Fresh-Cut Green Beans Sold In Egyptian Supermarkets

    International Nuclear Information System (INIS)

    Thirty samples of fresh-cut green beans were collected from different local supermarkets. They were tested for their microbiological quality. Total aerobic plate count (TAPC) of these samples ranged from >105 to 108 cfu/g; and total yeasts and moulds ranged from 102 to 105 cfu/g. All tested fresh-cut green beans samples were contaminated with E. coli. Only 6 samples were free from Enterococcus faecalis, the other 24 (80%) samples contained Ent. faecalis in the range of 102 to 104 cfu/g. Staphylococcus aureus was found in 20 samples (66.6 %) at level of 102 to 104 cfu/g. Aeromonas hydrophila was found in 22 (73.3 %) samples in the range of 102 to 103 cfu/g. All tested fresh cut green beans samples were free from Listeria monocytogenes and Salmonella spp. The D10-values of the isolated pathogenic bacteria (Ent. faecalis, Staph. aureus, E. coli and A. hydrophila) in fresh-cut green beans were found to be 0.58, 0.42, 0.23 and 0.11, respectively. Fresh-cut green beans samples were irradiated at 1.5 and 3.0 kGy, and then stored at refrigeration temperature (4 degree C ± 1). Generally, these radiation doses greatly reduced all microbial counts of fresh-cut green beans. The percentage of reduction reached 97.07 and 99.88 in TAPC. Irradiation dose of 1.5 kGy was enough for complete elimination of E. coli and A. hydrophila but was not sufficient for elimination of Ent. faecalis, and Staph. aureus. Irradiation dose of 3.0 kGy completely eliminated Ent. faecalis, and Staph. aureus present. This irradiation dose had no effect on sensorial quality attributes of fresh-cut green beans samples and extended the shelf-life to 15 days against only 5 days for unirradiated samples

    Impairments of executive functions (EF) significantly affect the ability to lead an independent lifestyle. Virtual environments offer a way to rehabilitate EF due to their ecological validity. The purpose of this pilot study was to examine the effectiveness of a virtual reality (VR) supermarket (VMall) for treatment of EF in patients with Traumatic Brain Injury (TBI), compared to conventional occupational therapy (OT), in order to provide initial data regarding the effect sizes for calculation of sample size as well as to establish an intervention protocol for future Randomized Control Trials (RCTs). Twelve men and women, aged 19-55 years, who had TBI resulting in EF impairments participated in this study. Outcome measures were the Multiple Errands Test-Simplified Version (MET-SV) and the Executive Function Performance Test (EFPT). Cognitive treatment provided to both groups was based on the same principles; the participants in the experimental group received 10 45-min VR-based treatment sessions and the control group participants received 10 sessions of occupational therapy cognitive retraining without VR. Baseline performance prior to intervention showed no statistically significant differences between groups. Most participants improved their performance after therapy. Following a Bonferroni correction for multiple comparisons, no significant between or within group differences were found, Nevertheless, large effect sizes (0.51) for the percent (%) relative change of the MET-SV total score and EFPT total score after intervention were high in favor of the experimental group indicating a larger improvement in EF. Based on this pilot study, results show a trend towards an advantage to VR therapy compared to cognitive retraining OT without VR, as it leads to greater improvement in complex everyday activities.

    In this study, a food survey was carried out with two purposes: (1) to investigate the levels of nickel (Ni), zinc (Zn), and copper (Cu) in various vegetables randomly collected in supermarkets of La Rochelle and (2) to assess the potential health risk for consumers by estimating the daily intake (EDI) and the target hazard quotient (THQ) for each heavy metal. The concentrations of Ni, Cu, and Zn in selected foodstuffs were detected within the following ranges: (3.2-9.6), (25.2-104.7), and (10.8-75.6) mg/kg (DW), respectively. Results showed that metals are more likely to accumulate in fruit vegetables (8.8, 63.8 and 47.8 mg/kg DW for Ni, Cu, and Zn, respectively), followed by leafy vegetables (6.5, 60.9 and 42.6 mg/kg DW for Ni, Cu, and Zn, respectively) and finally root vegetables (5.4, 40.0 and 27.3 mg/kg DW for Ni, Cu, and Zn, respectively). The levels of the metals match with those reported for similar vegetables from some other parts of the world. For all foodstuffs, EDI and THQ were below the threshold values for Cu (EDI 11.30; THQ 0.283) and Zn (EDI 6.86; THQ 0.023), while they exceeded the thresholds for Ni (EDI 20.71; THQ 1.035), indicating an obvious health risk over a life time of exposure.

    Full Text Available In recent years European Commission has developed a set of documents for Members States tracing, directly or indirectly, recommendations for the transformation of the European city. The paper wants to outline which future EU draws for the city, through an integrated and contextual reading of addresses and strategies contained in the last documents, a future often suggested as Smart City. Although the three main documents (Cohesion Policy 2014-2020 of European Community, Digital Agenda for Europe and European Urban Agenda face the issue of the future development of European cities from different points of view, which are respectively cohesion social, ICT and urban dimension, each of them pays particular attention to urban and territorial dimension, identified by the name of Smart City. In other words, the paper aims at drawing the scenario of evolution of Smart Cities that can be delineated through the contextual reading of the three documents. To this end, the paper is divided into three parts: the first part briefly describes the general contents of the three European economic plan tools; the second part illustrates the scenarios for the future of the European city contained in each document; the third part seeks to trace the evolution of the Smart Cities issue developed by the set of the three instruments, in order to provide the framework of European Community for the near future of our cities

    Open-type freezer displays are refrigeration equipment largely used for food conservation in commercial applications such as in supermarket stores. The energy consumption due to such equipment' may represent an important amount of the overall energy consumption of a supermarket, so that, store managers are generally interested in the application of procedures allowing to reduce their electricity costs due to refrigeration. A research was carried out, showing that in some supermarkets, both freezers displays and air conditioning systems are being shutdown during the night period, when the store is closed to consumers, in order to reduce energy consumption. However, while the expected reduction in electricity costs was not validated, an increase in the number of complaints from consumers with respect to products quality has been observed. This leads to conclude that, as expected, the absence of products refrigeration during the night is causing the degradation in food products quality. In order to analyze the potential of energy consumption reduction, a theoretical study was started based on the development of a mathematical model of a typical open-type freezer display. The model presented in the paper, is developed to predict the hourly energy demand of the equipment in response to design characteristics, conditioned space and seasonal conditions, cycling product charge-discharge operations, and food items thermal behavior. Preliminary results are presented allowing to study the influence of different operating conditions. The overall power consumption is first considered for standard operating conditions (reference) when both the freezer and the air conditioning system are running continuously. Simulation results for other conditions are then obtained and compared to the reference case. (author)

    Full Text Available Abstract Objective There has been limited study of all types of food stores, such as traditional (supercenters, supermarkets, and grocery stores, convenience stores, and non-traditional (dollar stores, mass merchandisers, and pharmacies as potential opportunities for purchase of fresh and processed (canned and frozen fruits and vegetables, especially in small-town or rural areas. Methods Data from the Brazos Valley Food Environment Project (BVFEP are combined with 2000 U.S. Census data for 101 Census block groups (CBG to examine neighborhood access to fruits and vegetables. BVFEP data included identification and geocoding of all food stores (n = 185 in six rural counties in Texas, using ground-truthed methods and on-site assessment of the availability and variety of fresh and processed fruits and vegetables in all food stores. Access from the population-weighted centroid of each CBG was measured using proximity (minimum network distance and coverage (number of shopping opportunities for a good selection of fresh and processed fruits and vegetables. Neighborhood inequalities (deprivation and vehicle ownership and spatial access for fruits and vegetables were examined using Wilcoxon matched-pairs signed-rank test and multivariate regression models. Results The variety of fruits or vegetables was greater at supermarkets compared with grocery stores. Among non-traditional and convenience food stores, the largest variety was found at dollar stores. On average, rural neighborhoods were 9.9 miles to the nearest supermarket, 6.7 miles and 7.4 miles to the nearest food store with a good variety of fresh fruits and vegetables, respectively, and 4.7 miles and 4.5 miles to a good variety of fresh and processed fruits or vegetables. High deprivation or low vehicle ownership neighborhoods had better spatial access to a good variety of fruits and vegetables, both in the distance to the nearest source and in the number of shopping opportunities.

  20. The City at Stake:

    Directory of Open Access Journals (Sweden)

    Sophie Esmann Andersen

    2009-12-01

    Full Text Available Studies of the city have been addressed from many different approaches such as law, political science, art history and public administration, in which the eco-nomic, political and legal status of the city have played a major role. However, a new agenda for conceptualizing the city has emerged, in which the city assumes new roles. By using stakeholder theory as a framework for conceptualizing the city, we argue that the city assumes a political-economic agenda-setting role as well as providing a stage for identity constructions and relational performances for consumers, organizations, the media, politicians and other stakeholders. Stakeholder theory allows us to conceptualize the city as being constituted by stakes and relationships between stakeholders which are approached from three analytical positions (modern, postmodern and hypermodern, respectively, thereby allowing us to grasp different stakes and types of relationships, ranging from functional and contractual relationships to individualized and emotionally driven or more non-committal and fluid forms of relationships. In order to support and illustrate the analytical potentials of our framework for conceptualizing urban living, we introduce a project which aims to turn the city of Aarhus into a CO2-neutral city by the year 2030, entitled Aarhus CO2030. We conclude that applying stakeholder theory to a hyper-complex organization such as a city opens up for a reconceptualization of the city as a web of stakes and stakeholder relations. Stakeholder theory contributes to a nuanced and elaborate understanding of the urban complexity and web of both enforced and voluntary relationships as well as the different types of relationships that characterize urban life.

    Great cities connect people; failed cities isolate people. Despite the fundamental importance of physical, face-to-face social-ties in the functioning of cities, these connectivity networks are not explicitly observed in their entirety. Attempts at estimating them often rely on unrealistic over-simplifications such as the assumption of spatial homogeneity. Here we propose a mathematical model of human interactions in terms of a local strategy of maximising the number of beneficial connections attainable under the constraint of limited individual travelling-time budgets. By incorporating census and openly-available online multi-modal transport data, we are able to characterise the connectivity of geometrically and topologically complex cities. Beyond providing a candidate measure of greatness, this model allows one to quantify and assess the impact of transport developments, population growth, and other infrastructure and demographic changes on a city.

  16. Universities Scale Like Cities

    van Raan, Anthony F J

    2012-01-01

    Recent studies of urban scaling show that important socioeconomic city characteristics such as wealth and innovation capacity exhibit a nonlinear, particularly a power law scaling with population size. These nonlinear effects are common to all cities, with similar power law exponents. These findings mean that the larger the city, the more disproportionally they are places of wealth and innovation. Local properties of cities cause a deviation from the expected behavior as predicted by the power law scaling. In this paper we demonstrate that universities show a similar behavior as cities in the distribution of the gross university income in terms of total number of citations over size in terms of total number of publications. Moreover, the power law exponents for university scaling are comparable to those for urban scaling. We find that deviations from the expected behavior can indeed be explained by specific local properties of universities, particularly the field-specific composition of a university, and its ...

    Various digital city projects, from the online cases (e.g. the America on Line) to the ubiquitous cities of South Korea, have achieved in creating technically 'physical' areas for the virtual communities, which share knowledge of common interest. Moreover, digital cities can succeed in simplifying citizen access to public information and services. Early digital cities deliver 'smart' and social services to citizens even with no digital skills, closing digital divide and establishing digital areas of trust in local communities. This paper presents the evolution of the digital cities, from the web to the ubiquitous architecture. It uses the latest digital city architecture and the current conditions of the digital city of Trikala (Greece), in order to present the evolution procedure of a digital city.

The conjunction of technology and city reformulates customs and social practices; it can even determine the way one constitutes one's own identity. One can see how close the relation is between technology (specifically, TICS and the structures of the city in a wide variety of situations: in social interactions on the street, in transport, and in ways of buying, of working and entertainment. "@City" is a concept that very well reflects the emergent properties of a current city, that is, the coexistence of a physical and a virtual urban space. The "22@Barcelona" project attempts to bring together different types of spaces. By combining the physical with the virtual, 22@Barcelona, as a neighborhood of @City, creates an uncertain and blurred border between both spaces.The article also examines the impact that these spaces have on the psycho-social processes involved in the daily life of a traditionally working-class neighborhood, now strongly limited by technological boundaries.

    2016-01-01

    The concept of a livable smart city presented in this book highlights the relevance of the functionality and integrated resilience of viable cities of the future. It critically examines the progressive digitalization that is taking place and identifies the revolutionized energy sector as the basis of urban life. The concept is based on people and their natural environment, resulting in a broader definition of sustainability and an expanded product theory. Smart City 2.0 offers its residents many opportunities and is an attractive future market for innovative products and services. However, it presents numerous challenges for stakeholders and product developers.

    Full Text Available Abstract Objective To determine the extent to which neighborhood needs (socioeconomic deprivation and vehicle availability are associated with two criteria of food environment access: 1 distance to the nearest food store and fast food restaurant and 2 coverage (number of food stores and fast food restaurants within a specified network distance of neighborhood areas of colonias, using ground-truthed methods. Methods Data included locational points for 315 food stores and 204 fast food restaurants, and neighborhood characteristics from the 2000 U.S. Census for the 197 census block group (CBG study area. Neighborhood deprivation and vehicle availability were calculated for each CBG. Minimum distance was determined by calculating network distance from the population-weighted center of each CBG to the nearest supercenter, supermarket, grocery, convenience store, dollar store, mass merchandiser, and fast food restaurant. Coverage was determined by calculating the number of each type of food store and fast food restaurant within a network distance of 1, 3, and 5 miles of each population-weighted CBG center. Neighborhood need and access were examined using Spearman ranked correlations, spatial autocorrelation, and multivariate regression models that adjusted for population density. Results Overall, neighborhoods had best access to convenience stores, fast food restaurants, and dollar stores. After adjusting for population density, residents in neighborhoods with increased deprivation had to travel a significantly greater distance to the nearest supercenter or supermarket, grocery store, mass merchandiser, dollar store, and pharmacy for food items. The results were quite different for association of need with the number of stores within 1 mile. Deprivation was only associated with fast food restaurants; greater deprivation was associated with fewer fast food restaurants within 1 mile. CBG with greater lack of vehicle availability had slightly better

    Full Text Available This photographic essay presents images from the City of London Asylum archive as a example of how the visual can be used to expand our investigations of social histories of Victorian London, particularly the multi-cultural nature of the city. The essay argues that images are an essential part of the research process, but also discusses some of the disadvantages and ethical tensions encountered through the use of such portraits for historical recovery. Despite these caveats, the paper concludes that we have much to learn from the images that present images of the city that would otherwise be difficult, if not impossible, for twenty-first-century researchers to access.

    2013-04-01

    Full Text Available In the quest for achieving sustainable cities, Intelligent and Knowledge City Programmes (ICPs and KCPs represent cost-efficient strategies for improving the overall performance of urban systems. However, even though nobody argues on the desirability of making cities “smarter”, the fundamental questions of how and to what extent can ICPs and KCPs contribute to the achievement of urban sustainability lack a precise answer. In the attempt of providing a structured answer to these interrogatives, this paper presents a methodology developed for investigating the modalities through which ICPs and KCPs contribute to the achievement or urban sustainability. Results suggest that ICPs and KCPs efficacy lies in supporting cities achieve a sustainable urban metabolism through optimization, innovation and behavior changes.

  1. Earthquakes in cities revisited

    CERN Document Server

    Wirgin, Armand

    2016-01-01

    During the last twenty years, a number of publications of theoretical-numerical nature have appeared which come to the apparently-reassuring conclusion that seismic motion on the ground in cities is smaller than what this motion would be in the absence of the buildings (but for the same underground and seismic load). Other than the fact that this finding tells nothing about the motion within the buildings, it must be confronted with the overwhelming empirical evidence (e.g, earthquakes in Sendai (2011), Kathmandu (2015), Tainan City (2016), etc.) that shaking within buildings of a city is often large enough to damage or even destroy these structures. I show, on several examples, that theory can be reconciled with empirical evidence, and suggest that the crucial subject of seismic response in cities is in need of more thorough research.

    2015-11-01

    In many coastal and delta cities land subsidence now exceeds absolute sea level rise up to a factor of ten. A major cause for severe land subsidence is excessive groundwater extraction related to rapid urbanization and population growth. Without action, parts of Jakarta, Ho Chi Minh City, Bangkok and numerous other coastal cities will sink below sea level. Land subsidence increases flood vulnerability (frequency, inundation depth and duration of floods), with floods causing major economic damage and loss of lives. In addition, differential land movement causes significant economic losses in the form of structural damage and high maintenance costs for (infra)structure. The total damage worldwide is estimated at billions of dollars annually. As subsidence is often spatially variable and can be caused by multiple processes, an assessment of subsidence in delta cities needs to answer questions such as: what are the main causes? What is the current subsidence rate and what are future scenarios (and interaction with other major environmental issues)? Where are the vulnerable areas? What are the impacts and risks? How can adverse impacts be mitigated or compensated for? Who is involved and responsible to act? In this study a quick-assessment of subsidence is performed on the following mega-cities: Jakarta, Ho Chi Minh City, Dhaka, New Orleans and Bangkok. Results of these case studies will be presented and compared, and a (generic) approach how to deal with subsidence in current and future subsidence-prone areas is provided.

    Full Text Available Abstract Background This paper addresses the statistical use of accessibility and availability indices and the effect of study boundaries on these measures. The measures are evaluated via an extensive simulation based on cluster models for local outlet density. We define outlet to mean either food retail store (convenience store, supermarket, gas station or restaurant (limited service or full service restaurants. We designed a simulation whereby a cluster outlet model is assumed in a large study window and an internal subset of that window is constructed. We performed simulations on various criteria including one scenario representing an urban area with 2000 outlets as well as a non-urban area simulated with only 300 outlets. A comparison is made between estimates obtained with the full study area and estimates using only the subset area. This allows the study of the effect of edge censoring on accessibility measures. Results The results suggest that considerable bias is found at the edges of study regions in particular for accessibility measures. Edge effects are smaller for availability measures (when not smoothed and also for short range accessibility Conclusions It is recommended that any study utilizing these measures should correct for edge effects. The use of edge correction via guard areas is recommended and the avoidance of large range distance-based accessibility measures is also proposed.
