Natural mineral waters may be an essential source of calcium, magnesium and other minerals. In bottled waters, minerals occur in an ionized form which is very well digestible. However, the concentration of minerals in underground waters (which constitute the material for the production of bottled waters) varies. In view of the above, the type of water consumed is essential. The aim of the study was to estimate the calcium and magnesium contents in products available on the market and to evaluate calcium and magnesium consumption with natural mineral water by different consumer groups with an assumed volume of the consumed product. These represented forty different brands of natural mineral available waters on Polish market. These waters were produced in Poland or other European countries. Among the studied products, about 30% of the waters were imported from Lithuania, Latvia, Czech Republic, France, Italy and Germany. The content of calcium and magnesium in mineral waters was determined using flame atomic absorption spectrometry in an acetylene-air flame. Further determinations were carried out using atomic absorption spectrometer--ICE 3000 SERIES-THERMO-England, equipped with a GLITE data station, background correction (a deuterium lamp) as well as other cathode lamps. Over half of the analysed natural mineral waters were medium-mineralized. The natural mineral waters available on the market can be characterized by a varied content of calcium and magnesium and a high degree of product mineralization does not guarantee significant amounts of these components. Among the natural mineral waters available on the market, only a few feature the optimum calcium-magnesium proportion (2:1). Considering the mineralization degree of the studied products, it can be stated that the largest percentage of products with significant calcium and magnesium contents can be found in the high-mineralized water group. For some natural mineral waters, the consumption of 1 litre daily may

When public health is endangered, the general public can only protect themselves if timely messages are received and understood. Previous research has shown that the cause of threats to public health can affect risk perception and behaviours. This study compares compliance to public health advice and consumer behaviour during two "Boil Water" notices issued in the UK due to a routine incident versus a natural disaster incident. A postal questionnaire was sent to 1000 randomly selected households issued a routine "Boil Water" notice. Findings were then compared to a previous study that explored drinking water behaviour during a "Boil Water" notice issued after serious floods. Consumers affected by the routine incident showed a significant preference for official water company information, whereas consumers affected by the natural disaster preferred local information sources. Confusion over which notice was in place was found for both incidents. Non-compliance was significantly higher for the natural disaster (48.3%) than the routine incident (35.4%). For the routine incident, compliance with advice on drinking as well as preparing/cooking food and brushing teeth was positively associated with receiving advice from the local radio, while the opposite was true for those receiving advice from the water company/leaflet through the post; we suggest this may largely be due to confusion over needing boiled tap water for brushing teeth. No associations were found for demographic factors. We conclude that information dissemination plans should be tailored to the circumstances under which the advice is issued. Water companies should seek to educate the general public about water notices and which actions are safe and unsafe during which notice, as well as construct and disseminate clearer advice on brushing teeth and preparing/cooking food.

Heat Pump Water Heater Technology: Experiences of Residential Consumers and Utilities

Energy Technology Data Exchange (ETDEWEB)

2004-08-04

This paper presents a case study of the residential heat pump water heater (HPWH) market. Its principal purpose is to evaluate the extent to which the HPWH will penetrate the residential market sector, given current market trends, producer and consumer attributes, and technical parameters. The report's secondary purpose is to gather background information leading to a generic framework for conducting market analyses of technologies. This framework can be used to compare readiness and to factor attributes of market demand back into product design. This study is a rapid prototype analysis rather than a detailed case analysis. For this reason, primary data collection was limited and reliance on secondary sources was extensive. Despite having met its technical goals and having been on the market for twenty years, the HPWH has had virtually no impact on contributing to the nation's water heating. In some cases, HPWH reliability and quality control are well below market expectations, and early units developed a reputation for unreliability, especially when measured against conventional water heaters. In addition to reliability problems, first costs of HPWH units can be three to five times higher than conventional units. Without a solid, well-managed business plan, most consumers will not be drawn to this product. This is unfortunate. Despite its higher first costs, efficiency of an HPWH is double that of a conventional water heater. The HPWH also offers an attractive payback period of two to five years, depending on hot water usage. On a strict life-cycle basis it supplies hot water very cost effectively. Water heating accounts for 17% of the nation's residential consumption of electricity (see chart at left)--water heating is second only to space heating in total residential energy use. Simple arithmetic suggests that this figure could be reduced to the extent HPWH technology displaces conventional water heating. In addition, the HPWH offers other

In recent years, governments, policy-makers, and managers of private food companies and agribusinesses are interested in understanding how consumers will react to environmentally sustainable attributes and information on food product labels. This study examines consumers' stated preferences for water and carbon footprints labelled food products from the viewpoint of black and white South Africans. Discrete choice experimental data was collected from black and white consumers to possibly assess cross-ethnic variations in preferences for environmentally sustainable products. Two widely purchased livestock products were chosen for the choice experiment. We found that consumers' preferences for environmentally sustainable attributes vary significantly between black and white South Africans. Our findings revealed that there are profound heterogeneous consumer segments within black and white respondents. The heterogeneity within both sub-samples is better explained at the segment level, rather than at individual level. For both product categories, the findings revealed that there are more distinct consumer segments among black respondents, relative to white respondents. The black respondents consist of water sustainability advocates, carbon reduction advocates, keen environmentalist and environmental neutrals. The white respondents entail keen environmentalist, environmental cynics, and environmental neutrals. The inherent significant variations in preferences for environmentally sustainable attributes across segments and racial groups would help in formulating feasible, and segment-specific environmental sustainability policies and marketing strategies aimed at changing consumers' attitude towards environmentally sustainable products. Demographic targeting of consumer segments, sustainability awareness and segment-specific educational campaigns meant to enhance subjective and objective knowledge on environmental sustainability are important tools for food companies and

The development of modern technologies in physiotherapy with the use of mineral waters, the expansion of the assortment of the medicinal and medicinal table waters as well as increasing the competitive advantages of domestic products require the more extensive marketing survey of the consumers' preferences in the market of mineral waters. The objective of the present study was the marketing evaluation of the consumers' preference in the segment of medicinal and medicinal table mineral waters in the city of Moscow. The survey involved 697 consumers of medicinal and medicinal table mineral waters. The sampling was carried out by the deterministic quota method. The field research was conducted by means of personal verbal interviews (32%) and the CATI to Web method (phone recruiting and on-line questioning) (68%) with the use of the structured questionnaire. Positioning was carried out making use of the two-dimensional schematic map and scoring assessment on an individual basis with calculation of integrated indicators. The marketing evaluation has demonstrated that the principal motive for purchasing mineral waters in more than 40% of respondents was the treatment and prevention of various diseases including disturbances in the urogenital system as well as digestive and respiratory disorders that appear to be the most frequent reasons for the consumption of mineral waters. The main factors that form the preferences of the consumers as regards the use of a concrete variety of mineral waters were elucidated. Of crucial importance for approximately 40% of the consumers (p<0.01) proved to be their health condition, the medical indications, and the available information about the therapeutic effectiveness of one or another type of mineral waters. Other factors were the quality of mineral water, its cost, the manufacturer and/or place of production, the attractiveness of the packaging, etc. The evaluation of the positioning of the mineral water consumers' preferences made

Self-concept as a significant determinant of brand choice and consumer buying behaviour

Full Text Available The need to predict consumer behavior outcomes is considered to be a very important issue for marketers. Today, one of the most popular psychological constructs in social sciences and marketing is the self-concept, as the total sum of ideas, thoughts and feelings through which individual can describe themselves in regards to other individuals in socially determined environment. The importance of self-concept in predicting consumer behavior and choice of brands has been recognized by many researchers. People tend to maintain and reinforce their self-concept by consumption of brands that have an image and personality in accordance to their own self-concept. Many studies have confirmed that high level of congruency between brand image/personality and consumer self-concept have positive influence on brand attitudes, preferences, evaluation of brands, buying intentions, satisfaction and brand loyalty. In this study, we have researched how has self-concept, as a psychological construct, gained in importance in the field of marketing research and practice. The concept is analyzed simultaneously as a psychological and marketing construct. By presenting literature review, we have also analysed the consequences of congruence between brand image/brand personality and consumer self-concept on consumer behavior and choice of brands. We have also pointed out the significance and references connected with the use of this concept for practical purposes in the realm of brand management. .

Can poor consumers pay for energy and water? An affordability analysis for transition countries

International Nuclear Information System (INIS)

Frankhauser, S.; Sladjana Tepic

2007-01-01

Low-income households spend a substantial share of their income on utility services such as electricity, heating and water. The difficulty of these socially vulnerable consumers to absorb further price increases is often used as an argument against tariff reform. However, detailed quantitative information on the affordability of tariff adjustments for low-income consumers is actually quite scarce. Much of the available information is based on households. This paper takes a more detailed look at the affordability of electricity, district heating and water for low-income consumers in transition countries. While the available data are incomplete, the paper finds that affordability is a problem for low-income consumers in most countries, in particular in the water sector and in the Commonwealth of Independent States (CIS). The affordability consequences of tariff reform ultimately depend on the speed of tariff adjustments relative to the growth in household income, the level of tariffs needed for cost recovery, the level of effective tariffs at the outset (tariffs adjusted for non-payment) and the demand response to the tariff increase. The paper finds that delaying tariff reform by a few years makes little difference to affordability constraints, and may therefore not be an effective way to mitigate the social impact of utility reform.

Common domestic solar water heating system usage patterns were investigated by a survey of 55 installations. These usage patterns were modelled by simulation based on the actual occupants' use of boiler or other auxiliary heating control strategies. These strategies were not optimal, as often assumed. The effectiveness of the technology was found to be highly sensitive to the time settings used for auxiliary water heating, and the 65% of solar householders using their boilers in the mornings were found to be forgoing 75% of their potential savings. Additionally, 92% of consumers were found to be small households, whose potential savings were only 23% of those of larger households, which use more hot water. Overall the majority (at least 60%) of the systems surveyed were found to be achieving no more than 6% of their potential savings. Incorporating consideration of Legionella issues, results indicate that if solar thermal technology is to deliver its potential to CO2 reduction targets: solar householders must avoid any use of their auxiliary water heating systems before the end of the main warmth of the day, grants for solar technology should be focused on households with higher hot water demands, and particularly on those that are dependent on electricity for water heating, health and safety requirements for hot water storage must be reviewed and, if possible, required temperatures should be set at a lower level, so that carbon savings from solar water heating may be optimized.

Because of concerns that natural aquifers in the region of Todos Santos (Baja California Sur, Mexico) might be contaminated by organochlorine pesticides and heavy metals, a case-control study was conducted among consumers and non-consumers of well- and/or tap-water to determine risks to human health. This study was based on a genotoxic evaluation of buccal cells using the Comet assay technique. Levels of DNA damage in the consumers group were significantly higher than those of the control group. However, occupational exposure to genotoxicants showed to be the critical factor rather than water consumption. Taking into account the professions of well- and/or tap-water consumers, agricultural workers exposed directly (those who fumigated) or indirectly (those not involved in fumigating) to agrochemicals showed greater genetic damage than controls. This difference persisted even when age, and whether the person smoked or consumed alcoholic drinks were considered. These factors were not associated with the level of genetic damage observed. Chemical analyses of organochlorine pesticides and heavy metals were carried out to evaluate the water quality of wells, faucets, and surface water of canals consumed by the population and/or used for irrigation. High concentrations of α and β endosulfan were detected in water of surface canals. Although our inventory of agrochemicals employed in the region showed the use of products considered carcinogenic and/or mutagenic, they were not detected by the analytical techniques used. Heavy metals (arsenic, mercury, and lead) were detected in water of some wells used for irrigation and human consumption. Environ. Mol.

The impact of consumer awareness of water sector issues on willingness to pay and cost recovery in Zambia

Science.gov (United States)

Ntengwe, F. W.

The recovery of costs in water utilities is a key element in sustainability of both the provider and of the water resource itself. This paper examines the role played by consumer awareness in their willingness to pay for water supply in two cities in Zambia. Research conducted in Kitwe and Lusaka reveals that level of awareness, willingness to pay and cost recovery all vary directly. Whereas awareness may increase consumers’ willingness to pay, therefore assisting service provider’s cost recovery, the research presented here also reveals that factors such as ability to pay, affordability of bills, quality of water and of the service provided, as well as good business-consumer relations are important factors affecting a utility’s ability to recover its costs. If water utilities are to attain sustainability over the long-term, they will have to embark on and maintain consumer awareness programmes, raise the quality of service (e.g., through improved operation and maintenance), and develop and apply the right water tariff.

Full Text Available The quality of the consumed drinking water may affect oral health. For example, the presence of iron in drinking water can cause aesthetic problems related to changes in dental enamel color. This study assessed the prevalence of extrinsic enamel color changes and their relationship with the quality of the water in the town of Caapiranga/AM-Brazil. Three hundred and forty six residents of the urban area were examined, and they also answered a questionnaire on eating habits and self-perceived oral health. As the initial results indicated an insufficient number of observations for the application of variance analysis (one-way ANOVA, the Student t test was chosen to compare levels of iron content in the water coming from two sources. The change in tooth color had a prevalence of 5.78% (20 people. The majority of the population (n = 261, 75.43% consumed well water. Those who presented extrinsic stains were uncomfortable with the appearance of their teeth (15.09%. We conclude that while there is excess of iron in the water in this region of Brazil, no association between extrinsic stains on the enamel and the level of iron in the water was found. There was a low prevalence of extrinsic stains in Caaparinga, being found only in children and adolescents. In the present study, an association between the presence of stains and the consumption of açai was determined, and those who presented them felt uncomfortable about their aesthetics.

Accounting for Water Insecurity in Modeling Domestic Water Demand

Science.gov (United States)

Galaitsis, S. E.; Huber-lee, A. T.; Vogel, R. M.; Naumova, E.

2013-12-01

Water demand management uses price elasticity estimates to predict consumer demand in relation to water pricing changes, but studies have shown that many additional factors effect water consumption. Development scholars document the need for water security, however, much of the water security literature focuses on broad policies which can influence water demand. Previous domestic water demand studies have not considered how water security can affect a population's consumption behavior. This study is the first to model the influence of water insecurity on water demand. A subjective indicator scale measuring water insecurity among consumers in the Palestinian West Bank is developed and included as a variable to explore how perceptions of control, or lack thereof, impact consumption behavior and resulting estimates of price elasticity. A multivariate regression model demonstrates the significance of a water insecurity variable for data sets encompassing disparate water access. When accounting for insecurity, the R-squaed value improves and the marginal price a household is willing to pay becomes a significant predictor for the household quantity consumption. The model denotes that, with all other variables held equal, a household will buy more water when the users are more water insecure. Though the reasons behind this trend require further study, the findings suggest broad policy implications by demonstrating that water distribution practices in scarcity conditions can promote consumer welfare and efficient water use.

Assessing Consumer Values and the Supply-Chain Market for the Integrated Water Heater/Dehumidifier

Energy Technology Data Exchange (ETDEWEB)

This paper presents a case study of the potential market for the dual-service residential integrated water heater/dehumidifier (WHD). Its principal purpose is to evaluate the extent to which this integrated appliance might penetrate the residential market sector, given current market trends, producer and consumer attributes, and technical parameters. The report's secondary purpose is to gather background information leading to a generic framework for conducting market analyses of technologies. This framework can be used to assess market readiness as well as factor preferred product attributes into the design to drive consumer demand for this product. This study also supports analysis for prototype design. A full market analysis for potential commercialization should be conducted after prototype development. The integrated WHD is essentially a heat-pump water heater (HPWH) with components and controls that allow dedicated dehumidification. Adequate residential humidity control is a growing issue for newly constructed residential homes, which are insulated so well that mechanical ventilation may be necessary to meet fresh air requirements. Leveraging its successful experience with the energy-efficient design improvement for the residential HPWH, the Oak Ridge National Laboratory's (ORNL's) Engineering Science and Technology Division's (ESTD's) Building Equipment Group designed a water-heating appliance that combines HPWH efficiency with dedicated dehumidification. This integrated appliance could be a low-cost solution for dehumidification and efficient electric water heating. ORNL is partnering with Western Carolina University, Asheville-Buncombe Technical Community College, American Carolina Stamping Company, and Clemson University to develop this appliance and assess its market potential. For practical purposes, consumers are indifferent to how water is heated but are very interested in product attributes such as initial first cost

Full Text Available Abstract Introduction: Today, water pipe smoking is widespread in the world that can lead to death of million individuals. This study aimed to determine the predictors of nicotine dependence among women water pipe consumers in Bushehr in 2013-2014. Methods: In this cross-sectional (descriptive and analytical study, 430 women water pipe smokers were selected via simple sampling and snowball methods. A structured interview was conducted on 20 women water pipe consumers in order to design a researcher-made questionnaire via appropriate statistical tests. The collected data were analyzed using SPSS statistical software. Results: The overall mean and standard deviation scores for nicotine dependence were 36.73±13.57 and 40.71±12.63, respectively. The highest and the lowest score were related to nicotine dependence and perceived behavioral control, respectively. All constructs explained water pipe dependence behavior except instrumental attitude and subjective norm. In fact, self-efficacy and affective attitude were introduced as the strongest and the weakest predictors respectively. Conclusion: Regarding unfavorable status of nicotine dependence behavior among water pipe consumer women, intervention programs are recommended in order to enhance the self-efficacy in decreasing this behavior, decrease appropriate affection to water pipe and decrease descriptive norm among these women.

2015-01-01

Little is known about the effect of serving temperature on saltiness perception in food products such as soups that are typically consumed at high temperature. This study focused on determining whether serving temperature modulates saltiness perception in soup-base products. Eight trained panelists and 62 untrained consumers were asked to rate saltiness intensities in salt water, chicken broth, and miso soup, with serving temperatures of 40, 50, 60, 70, and 80 °C. Neither trained nor untrained panelists were able to find significant difference in the saltiness intensity among salt water samples served at these five different temperatures. However, untrained consumers (but not trained panelists) rated chicken broth and miso soup to be significantly less salty when served at 70 and/or 80 °C compared to when served at 40 to 60 °C. There was an interaction between temperature-related perceived saltiness and preference; for example, consumers who preferred soups served at lower temperatures found soups served at higher temperatures to be less salty. Consumers who frequently consumed hot dishes rated soup samples served at 60 °C as saltier than consumers who consumed hot dishes less frequently. This study demonstrates that soup serving temperature and consumer dietary habits are influential factors affecting saltiness perception of soup. Published by Elsevier Ltd.

A tool to increase information-processing capacity for consumer water meter data

Directory of Open Access Journals (Sweden)

Heinz E. Jacobs

2012-02-01

Full Text Available Background: Water service providers invoice most South African urban consumers for the water they use every month. A secure treasury system generates water invoices at municipalities’ financial departments. Information about the water usage of customers initially comes from reading the water meters, usually located in gardens near the front boundaries of properties. Until as recently as 1990, the main purpose of the water meter readings was to generate invoices for water usage. There are various treasury systems for this purpose.Objective: The objective of this research article was to describe the development of Swift, a locally developed software tool for analysing water meter data from an information management perspective, which engineers in the water field generally use, and to assess critically the influence of Swift on published research and industry. This article focuses on water usage and the challenge of data interchange and extraction as issues that various industries face.Method: This article presents the first detailed report on Swift. It uses a detailed knowledge review and presents and summarises the findings chronologically.Results: The water meter data flow path used to be quite simple. The risk of breaches in confidentiality was limited. Technological advances over the years have led to additional knowledge coming from the same water meter readings with subsequent research outputs. However, there are also complicated data flow paths and increased risks. Users have used Swift to analyse more than two million consumers’ water meter readings to date. Studies have culminated in 10 peer-reviewed journal articles using the data. Seven of them were in the last five years.Conclusion: Swift-based data was the basis of various research studies in the past decade. Practical guidelines in the civil engineering fraternity for estimating water use in South Africa have incorporated knowledge from these studies. Developments after 1995 have

Extensive monitoring of conventional agricultural produce in the vicinity of the BNFL Sellafield plant is undertaken, by both the operator and the Ministry of Agriculture, Fisheries and Food, to determine levels of radioactivity and douses arising to the consumer Monitoring is also undertaken, albeit less extensively, for market garden and domestic produce. By contrast, few data exist with respect to levels of radioactivity in 'wild foods' (e.g. hedgerow fruits, field mushrooms etc.) or associated consumption habits. It has been postulated that such foodstuffs could contribute an appreciable radiation exposure dose to groups of high level consumers, potentially including members of the existing identified critical group for local agricultural produce. This paper assess the actual radiological significance of wild foods collected near Sellafield. (author)

Background There is evidence that household point-of-use (POU) water treatment products can reduce the enormous burden of water-borne illness. Nevertheless, adoption among the global poor is very low, and little evidence exists on why. Methods We gave 600 households in poor communities in Dhaka, Bangladesh randomly-ordered two-month free trials of four water treatment products: dilute liquid chlorine (sodium hypochlorite solution, marketed locally as Water Guard), sodium dichloroisocyanurate tablets (branded as Aquatabs), a combined flocculant-disinfectant powdered mixture (the PUR Purifier of Water), and a silver-coated ceramic siphon filter. Consumers also received education on the dangers of untreated drinking water. We measured which products consumers used with self-reports, observation (for the filter), and chlorine tests (for the other products). We also measured drinking water's contamination with E. coli (compared to 200 control households). Findings Households reported highest usage of the filter, although no product had even 30% usage. E. coli concentrations in stored drinking water were generally lowest when households had Water Guard. Households that self-reported product usage had large reductions in E. coli concentrations with any product as compared to controls. Conclusion Traditional arguments for the low adoption of POU products focus on affordability, consumers' lack of information about germs and the dangers of unsafe water, and specific products not meshing with a household's preferences. In this study we provided free trials, repeated informational messages explaining the dangers of untreated water, and a variety of product designs. The low usage of all products despite such efforts makes clear that important barriers exist beyond cost, information, and variation among these four product designs. Without a better understanding of the choices and aspirations of the target end-users, household-based water treatment is unlikely to reduce

Natural mineral bottled waters available on the Polish market as a source of minerals for the consumers. Part 2: The intake of sodium and potassium.

Science.gov (United States)

Gątarska, Anna; Ciborska, Joanna; Tońska, Elżbieta

Natural mineral waters are purchased and consumed according to consumer preferences and possible recommendations. The choice of appropriate water should take into account not only the general level of mineralization but also the content of individual components, including electrolytes such as sodium and potassium. Sodium is necessary to ensure the proper physiological functions of the body. It is defined as a health risk factor only when its excessive intake occurs. Potassium acts antagonistically towards sodium and calcium ions, contributes to a reduction of the volume of extracellular fluids and at the same time reduces muscle tension and permeability of cell membranes. The demand for sodium and potassium is of particular importance in people expending significant physical effort, where an increased electrolyte supply is recommended. The aim of the study was to estimate the content of sodium and potassium in natural mineral waters available in the Polish market and to evaluate the intake of those components with the commercially available mineral waters by different groups of consumers at the assumed volume of their consumption. The research material consisted of natural mineral waters of forty various brands available on the Polish market. The examined products were either produced in Poland or originated in other European countries. Among the products under examination, about 30% of the waters were imported from Lithuania, Latvia, the Czech Republic, France, Italy and Germany. A sample for analyses consisted of two package units of the examined water from different production lots. Samples for research were collected at random. The study was conducted with the same samples in in which calcium and magnesium content was determined, which was the subject of the first part of the study. The content of sodium and potassium was determined using the emission technique (acetylene-air flame), with the use of atomic absorption spectrometer – ICE 3000 SERIES – THERMO

2017-12-01

To investigate the effects of unequal supply hours on consumers' coping strategies and perceptions of the intermittent water supply (IWS) in the Kathmandu Valley (KV), Nepal we conducted a randomized household survey (n=369) and on-site water quality tests. Half of the households received piped water for 6 or fewer hours per week. To augment or cope with the inadequate supply, 28% of the households used highly contaminated and expensive tanker-delivered water. Half of the piped water samples (n=13) were contaminated with Escherichia coli. Free chlorine concentration in all piped water samples was below the national standards (0.1-0.2mg/L), but combined chlorine was detected at an average of 0.24mg/L, indicating ingression of contaminants in the network. Point-of-use devices could increase access to safe water in the KV from 42% to 80%. The use of Lorenz curves and Gini coefficients revealed inequality of piped water supply hours per week both between and within service areas in the KV, due mainly to a small percentage of households who receive longer supply hours. To cope with reduced supply hours, home owners pay more to get water from alternative sources, while tenants compromise their water consumption. Under IWS, expectations for improvements in piped water quality and supply regularity are higher than those for supply volume. Consumers' perceptions of the piped water services worsen with the reduction in supply hours, but perceptions of piped water tariff are independent of supply hours. Copyright © 2017 Elsevier B.V.

Egglestone, Corin; Morris, Anne; O'Brien, Ann

2013-10-01

Direct-to-consumer (DTC) genetic tests can be purchased over the internet. Some companies claim to provide relative genetic risks for various diseases and thus encourage healthy behaviour. There are concerns that exposure to such information may actually discourage healthy behaviour or increase health anxiety. An online survey was conducted (n = 275). Respondents were composed of individuals who had purchased a DTC genetic test and received their results (consumers, n = 189), as well as individuals who were either awaiting test results or considering purchasing a test (potential consumers, n = 86). Consumers were asked if their health behaviour or health anxiety had changed after receiving their results. Respondents' current health behaviour and health anxiety were queried and compared. In total, 27.3 % of consumers claimed a change in health behaviour, all either positive or neutral, with no reported cessation of any existing health behaviour. A change in health anxiety was claimed by 24.6 % of consumers, 85.3 % of which were a reduction. Consumers had significantly better health behaviour scores than potential consumers (p = 0.02), with no significant difference in health anxiety. This study points towards an association between receipt of DTC genetic test results and increased adoption of healthy behaviours for a minority of consumers based on self-report, with more mixed results in relation to health anxiety.

Biotechnology and Consumer Decision-Making.

Science.gov (United States)

Sax, Joanna K

Society is facing major challenges in climate change, health care and overall quality of life. Scientific advances to address these areas continue to grow, with overwhelming evidence that the application of highly tested forms of biotechnology is safe and effective. Despite scientific consensus in these areas, consumers appear reluctant to support their use. Research that helps to understand consumer decision-making and the public’s resistance to biotechnologies such as vaccines, fluoridated water programs and genetically engineered food, will provide great social value. This article is forward-thinking in that it suggests that important research in behavioral decision-making, specifically affect and ambiguity, can be used to help consumers make informed choices about major applications of biotechnology. This article highlights some of the most controversial examples: vaccinations, genetically engineered food, rbST treated dairy cows, fluoridated water, and embryonic stem cell research. In many of these areas, consumers perceive the risks as high, but the experts calculate the risks as low. Four major thematic approaches are proposed to create a roadmap for policymakers to consider for policy design and implementation in controversial areas of biotechnology. This article articulates future directions for studies that implement decision-making research to allow consumers to appropriately assign risk to their options and make informed decisions.

THE ROLE OF FARMERS IN MANAGING WATER Dr Tony Colman Professor Tony Allan Farmers manage about 92% of the water consumed by society which needs to recognise that farming practices and the decisions made by those who operate food supply chains - including corporates and those making public policy - determine how water is stewarded.

Title Food-water and society Dr. Tony Colman and Professor Tony Allan Abstract The purpose of the paper is to highlight some key relationships between water resources and society. First, water is an very important resource for society in that it provides an essential input to society's food supply chains. Secondly, it is an essential input to farmer livelihoods. About half of the families of the world still work in agriculture - albeit a declining proportion. Thirdly, farmers manage about 92% of the water consumed by society - including the blue water (surface and groundwater) for irrigation and the green water (effective rainfall) consumed on rainfed farms. They also account for about 66% of society's impacts on biodiversity and about 25% of emissions. Finally it will be argued that those who analyse allocation and management of water must recognise that farming practices and the decisions made by those who operate food supply chains - including corporates and those making public policy - must recognise that it is farmers and food consumers who determine how water is stewarded. It will be suggested that we need to understand that well informed consumers could be the regulators.

Consumer participation in housing: reflecting on consumer preferences.

Browne, Graeme; Hemsley, Martin

2010-12-01

Historically, people living with mental illness have had limited chance to participate in mental health services other than as patients. Following on from a recent review focusing on consumer participation in mental health services, this paper looks at consumer participation in housing. Housing is a critical element in recovery from mental illness. Without suitable housing, people have little chance of maintaining other resources in their lives, such as supportive social relationships and meaningful activities. Consumer participation is not a common topic in the recent literature, despite the significant public policy push to promote it. The importance of appropriate housing to the recovery of people living with mental illness cannot be underestimated. Even well-meaning and well-resourced housing initiatives can fall short of meeting consumers' recovery goals when they do not incorporate the expressed needs of consumers. These expressed needs include keeping units small in size and employing drop-in support models.

2006-01-01

Full Text Available The paper deals with consumer behavior on the market with selected food products. It focuses on expenditures on food, development of prices and comparison of results among EU countries. When comparing the development of consumer prices and incomes in 1990–2003, it is obvious that the growth of income was lower then the total increase of consumer prices. There were not only changes in price levels, but also in the structure of consumer expenditures, where we can see growth of expenditures for housing and decline in share of expenditures for food. In the Czech Republic, there was a decrease in consumption of beef and pork meet, and increase in poultry consumption. The consumption of fish is significantly below the EU average. Consumption of butter, potatoes and sugar reaches the similar level as the EU average. The analysis of motives for changes in consumption of selected foodstuffs provides some insight in reasons for changes in consumption of bakery products and sweets, where it mostly is the healthy lifestyle (motive for whole-grain bakery product consumption and improved market offer and advertising (for sweets and durable bakery products. Changes in meat consumption are motivated by healthy lifestyle for poultry and fish and improved market offer and advertising for canned meat products and salamis. Advertising and improved market offer played an important role for changes in consumption of yoghurts and cheeses, healthy lifestyle caused changes of yoghurts and milk. In category of selected beverages, it were advertising and improved market offer the motives for change of consumption of tea, wine and mineral waters, while healthy lifestyle motivated the change of mineral water consumption.

Surface water change as a significant contributor to global evapotranspiration change

Science.gov (United States)

Zhan, S.; Song, C.

2017-12-01

Water comprises a critical component of global/regional hydrological and biogeochemical cycles and is essential to all organisms including humans. In the past several decades, climate change has intensified the hydrological cycle, with significant implications for ecosystem services and feedback to regional and global climate. Evapotranspiration (ET) as a linking mechanism between land surface and atmosphere is central to the water cycle and an excellent indicator of the intensity of water cycle. Knowledge of the temporal changes of ET is crucial for accurately estimating global or regional water budgets and better understanding climate and hydrological interactions. While studies have examined changes in global ET, they were conducted using a constant land and surface water (SW) area. However, as many studies have found that global SW is very dynamic and their surface areas have generally been increasing since the 1980s. The conversion from land to water and vice versa significantly changes the local ET since water bodies evaporate at a rate that can be much higher than that of the land. Here, we quantify the global changes in ET caused by such land-water conversion using remotely-sensed SW area and various ET and potential ET products. New SW and lost SW between circa-1985 and circa-2015 were derived from remote sensing and were used to modify the local ET estimates. We found an increase in ET in all continents as consistent with the net increase in SW area. The increasing SW area lead to a global increase in ET by 30.38 ± 5.28 km3/yr. This is a significant contribution when compared to the 92.95 km3/yr/yr increase in ET between 1982-1997 and 103.43 km3/yr/yr decrease between 1998-2008 by Jung et al., (2010) assuming a constant SW. The results enhance our understanding of the water fluxes between the land and atmosphere and supplement land water budget estimates. We conclude that changes in SW lead to a significant change in global ET that cannot be neglected in

Environmental assessment. Energy efficiency standards for consumer products

Energy Technology Data Exchange (ETDEWEB)

McSwain, Berah

1980-06-01

The Energy Policy and Conservation Act of 1975 requires DOE to prescribe energy efficiency standards for 13 consumer products. The Consumer Products Efficiency Standards (CPES) program covers: refrigerators and refrigerator-freezers, freezers, clothes dryers, water heaters, room air conditioners, home heating equipment, kitchen ranges and ovens, central air conditioners (cooling and heat pumps), furnaces, dishwashers, television sets, clothes washers, and humidifiers and dehumidifiers. This Environmental Assessment evaluates the potential environmental and socioeconomic impacts expected as a result of setting efficiency standards for all of the consumer products covered by the CPES program. DOE has proposed standards for eight of the products covered by the Program in a Notice of Proposed Rulemaking (NOPR). DOE expects to propose standards for home heating equipment, central air conditioners (heat pumps only), dishwashers, television sets, clothes washers, and humidifiers and dehumidifiers in 1981. No significant adverse environmental or socioeconomic impacts have been found to result from instituting the CPES.

Full Text Available Matcha green tea powder (MGTP is made with finely ground green tea leaves that are rich in phytochemicals, most particularly catechins. Shortbread biscuits were enriched with MGTP and evaluated for consumer acceptability and potential functional health properties. Baking decreased the content of total catechins by 19% compared to dough, although epimerization increased the amount of (+-gallocatechin gallate at the expense of other catechins such as (−-epigallocatechin gallate. Consumer acceptability tests using a 9-point hedonic scale showed that consumers preferred enriched biscuits with low content of MGTP (2 g of MGTP 100 g−1 of flour, and an increase of sugar content did not significantly improve the acceptability of MGTP-enriched biscuits. Overall, enrichment of biscuits with MGTP did not significantly affect the postprandial glucose or triglyceride response (area under curve compared to non-enriched biscuits consumed with water or MGTP drink. Enriching biscuits with Matcha green tea is acceptable to consumers, but may not bring significant postprandial effects.

Over 5 billion people worldwide are exposed to unsafe water. Given the obstacles to ensuring sustainable improvements in water supply infrastructure and the unhygienic handling of water after collection, household water treatment and storage (HWTS) products have been viewed as important mechanisms for increasing access to safe water. Although studies have shown that HWTS technologies can reduce the likelihood of diarrheal illness by about 30%, levels of adoption and continued use remain low. An understanding of household preferences for HWTS products can be used to create demand through effective product positioning and social marketing, and ultimately improve and ensure commercial sustainability and scalability of these products. However, there has been little systematic research on consumer preferences for HWTS products. This paper reports the results of the first state-of-the-art conjoint analysis study of HWTS products. In 2008, we conducted a conjoint analysis survey of a representative sample of households in Andhra Pradesh (AP), India to elicit and quantify household preferences for commercial HWTS products. Controlling for attribute non-attendance in an error components mixed logit model, the study results indicate that the most important features to respondents, in terms of the effect on utility, were the type of product, followed by the extent to which the product removes pathogens, the retail outlet and, the time required to treat 10 L. Holding all other product attributes constant, filters were preferred to combination products and chemical additives. Department stores and weekly markets were the most favorable sales outlets, followed by mobile salespeople. In general, households do not prefer to purchase HWTS products at local shops. Our results can inform the types of products and sales outlets that are likely to be successful in commercial HWTS markets in AP, as well as the influence of different pricing and financing strategies on product demand

Significance of metabolites in the environmental risk assessment of pharmaceuticals consumed by human.

Han, Eun Jeong; Lee, Dong Soo

2017-08-15

The purpose of this study is to demonstrate the significance of metabolites to the ERA of human pharmaceuticals. The predicted exposure concentrations (PECs) in surface water were estimated for a total of 24 selected active pharmaceutical ingredients (APIs) and their metabolites using a life cycle based emission estimation model combined with a multimedia fate model with Monte-Carlo calculations. With the eco-toxicity data, the hazard quotients (HQs) of the metabolites were compared with those of individual parents alone. The results showed that PEC or toxicity or both of the metabolites was predicted to be higher than that of their parent APIs, which resulted in a total of 18 metabolites (from 12 parents) that have greater HQs than their parents. This result clearly demonstrated that some metabolites may potentially pose greater risk than their parent APIs in the water environment. Therefore, significance of metabolites should be carefully evaluated for monitoring strategy, priority setting, and scoping of the environmental risk assessment of APIs. The method used in the present work may serve as a pragmatic approach for the purpose of preliminary screening or priority setting of environmental risk posed by both APIs and their metabolites.

Narayanan, Sekharipuram; Kindler, Andrew; Valdez, Thomas

2007-01-01

In a proposed direct methanol fuel-cell electric-power-generating system, the fuel cells would consume neat methanol, in contradistinction to the dilute aqueous methanol solutions consumed in prior direct methanol fuel-cell systems. The design concept of the proposed fuel-cell system takes advantage of (1) electro-osmotic drag and diffusion processes to manage the flows of hydrogen and water between the anode and the cathode and (2) evaporative cooling for regulating temperature. The design concept provides for supplying enough water to the anodes to enable the use of neat methanol while ensuring conservation of water for the whole fuel-cell system.

The European Union Water Framework Directive (EU WFD) is a unique piece of legislation, which may be of great significance to on - going reforms of the water sector in China. First and foremost it unites 27 European mem- ber states behind a common goal, which is "to achieve good chemical and ecological status" of all water bodies across the EU. Other significant characteristics of the EU WFD are that (1) it sets a clear timeframe with a number of time - bound actions for member states to achieve the goal, hut leaves it to member states to achieve this goal in a decent- ralised process, which makes allowance for the different socio - economic conditions, (2) it defines the river basin as the management unit for water thus departing with the traditional fragmented management by administrative units and it appoints a single competent authority for water management within each fiver basin, thus facilitating resolution of sector conflicts, (3) it requires a financial and economic analysis of the costs of implementing the EU WFD to enable deci- sion makers to assess whether the required improvements are affordable to government and to the population within the fiver basin, and (4) it requires a structured process for information and consultation with stakeholders and the public throughout the planning and implementation process.

Full Text Available Data collection or generation is the primary way that the majority of volunteers advance the scientific goals of citizen science projects, but other activities such as data consumption also may influence learning, civic, and conservation outcomes. Project designers and managers balance goals for multiple outcomes and thus need to consider the influence of all project-related activities on outcomes. In a study of the kayak-based Citizen’s Water Quality Testing (CWQT Program in New York City, we compared the characteristics, perceptions, and behaviors of those collecting and using CWQT data (data collectors and those solely using the data (data consumers. Data collectors (n = 40 and consumers (n = 24 were similar in gender and political orientation, but collectors were younger, devoted more time to the project, and experienced far more face-to-face interactions related to the project. Data collectors and consumers had similar motivations for participation, except that collectors were more likely motivated by recognition for their efforts. Lack of free time was the largest barrier to participation for both types of participants, and a significantly greater barrier for consumers. Data collectors and consumers trusted volunteer-collected data more than government-collected data. Collectors and consumers both recognized multiple scientific, environmental, and social benefits associated with the project, and both were equally likely to use volunteer-collected data for a variety of purposes, such as informing decisions about conservation and recreation. Importantly, both groups were equally likely to undertake a suite of conservation behaviors. We synthesize and expand current conceptual frameworks of citizen science participation and outcomes, highlighting the need for further study to understand mechanisms and linkages between the varied activities of citizen science projects and broader social and ecological impacts.

As the fifth global water footprint assessment, this study enhanced previous estimates of national blue water consumption (including fresh surface and groundwater) and main economic activities with (1) improved spatial and sectoral resolution and (2) quantified the impacts of virtual water trade on water use and water stress at both the national and basin level. In 2007, 1194 Gm(3) of blue water was consumed globally for human purposes. The consuming (producing) of primary and manufactured goods and services from the sectors of "Primary Crops and Livestock", "Primary Energy and Minerals", "Processed Food and Beverages", "Non-food Manufactured Products", "Electricity", "Commercial and Public Services", and "Households" accounted for 33% (91%), ∼ 0% (1%), 37% (water consumption, respectively. The considerable differences in sectoral water consumption accounted for by the two perspectives (consumption- vs production-based) highlight the significance of the water consumed indirectly, upstream in the supply chain (i.e., > 70% of total blue water consumption) while offering additional insights into the water implications of critical interconnected economic activities, such as the water-energy nexus. With 145 Gm(3) (12%) of the blue water consumption embedded in the goods and services traded internationally, 89 countries analyzed were net blue water importers at the national level. On the basin level, the impacts of virtual water trade on water stress were statistically significant for basins across the world and within 104 countries; virtual water trade mitigated water stress for the basins within 85 of the 104 countries, including all of those where there are moderate and greater water stress countrywide (except Italy).

Impact of Large Scale Energy Efficiency Programs On Consumer Tariffs and Utility Finances in India

Energy Technology Data Exchange (ETDEWEB)

Abhyankar, Nikit; Phadke, Amol

2011-01-20

Large-scale EE programs would modestly increase tariffs but reduce consumers' electricity bills significantly. However, the primary benefit of EE programs is a significant reduction in power shortages, which might make these programs politically acceptable even if tariffs increase. To increase political support, utilities could pursue programs that would result in minimal tariff increases. This can be achieved in four ways: (a) focus only on low-cost programs (such as replacing electric water heaters with gas water heaters); (b) sell power conserved through the EE program to the market at a price higher than the cost of peak power purchase; (c) focus on programs where a partial utility subsidy of incremental capital cost might work and (d) increase the number of participant consumers by offering a basket of EE programs to fit all consumer subcategories and tariff tiers. Large scale EE programs can result in consistently negative cash flows and significantly erode the utility's overall profitability. In case the utility is facing shortages, the cash flow is very sensitive to the marginal tariff of the unmet demand. This will have an important bearing on the choice of EE programs in Indian states where low-paying rural and agricultural consumers form the majority of the unmet demand. These findings clearly call for a flexible, sustainable solution to the cash-flow management issue. One option is to include a mechanism like FAC in the utility incentive mechanism. Another sustainable solution might be to have the net program cost and revenue loss built into utility's revenue requirement and thus into consumer tariffs up front. However, the latter approach requires institutionalization of EE as a resource. The utility incentive mechanisms would be able to address the utility disincentive of forgone long-run return but have a minor impact on consumer benefits. Fundamentally, providing incentives for EE programs to make them comparable to supply

Residential water demand and water consumption: an econometric analysis on municipal panel data

International Nuclear Information System (INIS)

Musolesi, Antonio; Nosvelli, Mario

2005-01-01

This paper focuses on residential water demand estimation, a rather neglected issue in the Italian environmental economics literature as compared to other European countries and the USA. This may depend on the difficulties in gathering proper data and, most of all, panel data. In some cases statistical information are not suitably collected, while in other cases legal privacy ties put some obstacles to data set transfer. Our panel data set refers to 102 municipalities in Lombardy (Italy) for the period 1998-2002. When estimating the effect of water price, we control for other relevant variables such as: income, households demographical variables - (age structure, number of component for each family) number of firms in tertiary sector, water system length. In the considered period, the data show both an increase in population (1,5 %) and in the number of water consumers (7%) associated, on aggregate, with a slight reduction in water consumption (-1,1 %). Water demand models are estimated both in a static and in a dynamic framework. In the former, the emphasis is set on the sources of endogeneity in the average price by estimating a system of simultaneous equations and relevant variables for assessing consumer behaviour - such as socio demographic ones - are incorporated in the model. In the latter, econometric methods especially designed for endogeneity in panel data models (Arellano e Bond, 1991), are employed in order to estimate the long run elasticity of water demand with respect to average price. We find evidence both that consumers significantly respond to average price only in the long run with an elasticity of about - 0,3-0,4 and that income and demographic variables are crucial in explaining consumers' behaviour. Furthermore, water consumption presents a strong auto-regressive component, showing the emergence of inertia and path dependency in consumption habits. Such results suggest important implications for water policy planning. On one side demographic

Contaminated water sources are major cause of water borne diseases of public health importance. Usually, contamination is suspected after an increase in patient load. Two health teams investigated the episode. First team conducted sanitary survey, and second team undertook water safety and morbidity survey. On-site testing was carried out from source till consumer end. Investigation was also undertaken to identify factors which masked the situation. Prevention and control measures included super chlorination, provision of alternate drinking water sources, awareness campaign, layout of new water pipeline bypassing place of contamination, repair of sewers, flushing and cleaning of water pipelines, and repeated water sampling and testing. Multiple sources of drinking water supply were detected. Water samples from consumer end showed 18 coliforms per 100 ml. Sewer cross connection with active leakage in water pipeline was found and this was confirmed by earth excavation. Water safety and morbidity survey found majority of households receiving contaminated water supply. This survey found no significant difference among households receiving contaminated water supply and those receiving clean water. Average proportion of household members with episode of loose motions, pain abdomen, vomiting, fever, and eye conditions was significantly more among households receiving contaminated water. The present study documents detailed methodology of investigation and control measures to be instituted on receipt of contaminated water samples. Effective surveillance mechanisms for drinking water supplies such as routine testing of water samples can identify water contamination at an early stage and prevent an impending outbreak.

Full Text Available This research was aimed at gaining relevant knowledge about the attitudes of Podgorica consumers toward advertising through sport among the question how often consumers purchase sporting goods. The sample included 330 students from Faculty of Economics in Podgorica, divided into six subsample groups: consumers who do not purchase sport goods at all, then consumers who purchase sport goods less than ones a month, next 1–3 a month, 4–6 a month, 7–9 a month, as well as consumers who purchase sport goods more than 10 times a month. The sample of variables contained the system of three general attitudes which were modelled by seven-point Likert scale. The results of the measuring were analyzed by multivariate analysis (MANOVA and univariate analysis (ANOVA and Post Hoc test. Based on the statistical analyses it was found that significant differences occur at multivariate level, as well as between all three variables at a significance level of (p=.000. Hence, it is interesting to highlight that it was found there were significant differences showed up between the consumers who purchase sport goods. The significant differences were found in two of three variables, while the consumers who purchase sport goods less than 3 times a moths had much more negative attitudes toward advertising though sport.

2013-10-15

Shale gas production represents a large potential source of natural gas for the nation. The scale and rapid growth in shale gas development underscore the need to better understand its environmental implications, including water consumption. This study estimates the water consumed over the life cycle of conventional and shale gas production, accounting for the different stages of production and for flowback water reuse (in the case of shale gas). This study finds that shale gas consumes more water over its life cycle (13-37 L/GJ) than conventional natural gas consumes (9.3-9.6 L/GJ). However, when used as a transportation fuel, shale gas consumes significantly less water than other transportation fuels. When used for electricity generation, the combustion of shale gas adds incrementally to the overall water consumption compared to conventional natural gas. The impact of fuel production, however, is small relative to that of power plant operations. The type of power plant where the natural gas is utilized is far more important than the source of the natural gas.

The blue water footprint of electricity from hydropower

Directory of Open Access Journals (Sweden)

M. M. Mekonnen

2012-01-01

Full Text Available Hydropower accounts for about 16% of the world's electricity supply. It has been debated whether hydroelectric generation is merely an in-stream water user or whether it also consumes water. In this paper we provide scientific support for the argument that hydroelectric generation is in most cases a significant water consumer. The study assesses the blue water footprint of hydroelectricity – the water evaporated from manmade reservoirs to produce electric energy – for 35 selected sites. The aggregated blue water footprint of the selected hydropower plants is 90 Gm³ yr⁻¹, which is equivalent to 10% of the blue water footprint of global crop production in the year 2000. The total blue water footprint of hydroelectric generation in the world must be considerably larger if one considers the fact that this study covers only 8% of the global installed hydroelectric capacity. Hydroelectric generation is thus a significant water consumer. The average water footprint of the selected hydropower plants is 68 m³ GJ⁻¹. Great differences in water footprint among hydropower plants exist, due to differences in climate in the places where the plants are situated, but more importantly as a result of large differences in the area flooded per unit of installed hydroelectric capacity. We recommend that water footprint assessment is added as a component in evaluations of newly proposed hydropower plants as well as in the evaluation of existing hydroelectric dams, so that the consequences of the water footprint of hydroelectric generation on downstream environmental flows and other water users can be evaluated.

Acidic whey protein beverages are a growing component of the functional food and beverage market. These beverages are also astringent, but astringency is an expected and desirable attribute of many beverages (red wine, tea, coffee) and may not necessarily be a negative attribute of acidic whey protein beverages. The goal of this study was to define the consumer perception of astringency in clear acidic whey protein beverages. Six focus groups (n=49) were held to gain understanding of consumer knowledge of astringency. Consumers were presented with beverages and asked to map them based on astringent mouthfeel and liking. Orthonasal thresholds for whey protein isolate (WPI) in water and flavored model beverages were determined using a 7-series ascending forced choice method. Mouthfeel/basic taste thresholds were determined for WPI in water. Acceptance tests on model beverages were conducted using consumers (n=120) with and without wearing nose clips. Consumers in focus groups were able to identify astringency in beverages. Astringency intensity was not directly related to dislike. The orthonasal threshold for WPI in water was lower (P astringent mouthfeel and that both flavor and astringency should be the focus of ongoing studies to improve the palatability of these products. © 2010 Institute of Food Technologists®

This is Volume 3 in a series of documents on energy efficiency of consumer products. This volume discusses energy efficiency of water heaters. Water heaters are defined by NAECA as products that utilize oil, gas, or electricity to heat potable water for use outside the heater upon demand. These are major appliances, which use a large portion (18% on average) of total energy consumed per household (1). They differ from most other appliances in that they are usually installed in obscure locations as part of the plumbing and are ignored until they fail. Residential water heaters are capable of heating water up to 180{degrees}F, although the setpoints are usually set lower.

The effects of an alginate-based edible coating containing natural antioxidants (rosemary and oregano essential oils) on lipid oxidation, color preservation, water losses, texture and pH of beef steaks during 14 days of display were studied. The essential oil, edible coating and beef antioxidant activities, and beef consumer acceptability were also investigated. The edible coatings decreased lipid oxidation of the meat compared to the control. The coating with oregano was most effective (46.81% decrease in lipid oxidation) and also showed the highest antioxidant activity. The coatings significantly decreased color losses, water losses and shear force compared to the control. The coatings had a significant effect on consumer perception of odor, flavor and overall acceptance of the beef. In particular, the oregano coating showed significantly high values (approximately 7 in a 9-point scale). Active edible coatings containing natural antioxidants could improve meat product stability and therefore have potential use in the food industry. PMID:27504957

Optimal Intermittent Operation of Water Distribution Networks under Water Shortage

Directory of Open Access Journals (Sweden)

mohamad Solgi

2017-07-01

Full Text Available Under water shortage conditions, it is necessary to exercise water consumption management practices in water distribution networks (WDN. Intermittent supply of water is one such practice that makes it possible to supply consumption nodal demands with the required pressure via water cutoff to some consumers during certain hours of the day. One of the most important issues that must be observed in this management practice is the equitable and uniform water distribution among the consumers. In the present study, uniformity in water distribution and minimum supply of water to all consumers are defined as justice and equity, respectively. Also, an optimization model has been developed to find an optimal intermittent supply schedule that ensures maximum number of demand nodes are supplied with water while the constraints on the operation of water distribution networks are also observed. To show the efficiency of the proposed model, it has been used in the Two-Loop distribution network under several different scenarios of water shortage. The optimization model has been solved using the honey bee mating optimization algorithm (HBMO linked to the hydraulic simulator EPANET. The results obtained confirm the efficiency of the proposed model in achieving an optimal intermittent supply schedule. Moreover, the model is found capable of distributing the available water in an equitable and just manner among all the consumers even under severe water shoratges.

Cristina Burghelea

2014-05-01

Full Text Available In the era of technological change, consumers face an environment increasingly complex, leading to significant challenges regarding buying and consuming choices and consumer protection. The most important and most influential technological changes in terms of the impact on the consumer, are iduced by internet, digitization and globalization. However, the era of technological change also means developing biotechnologies, nanotechnologies, new materials and new energy sources, all these changing people`s lives, living conditions, their needs and their behaviour as consumers. The literature highlights the factors that influence purchasing behaviour and changes manifested in terms of values, stressing the importance of promoting and protecting consumer`s rights and interests, The new responsible consumer can become a key driving force of sustainable development only if it is able to capitalize on new opportunities and to counter new risks of modern marketing technologies based on the Internet and mobile communications. This involves the assimilation of new knowledge throughout life to keep up with the accelerating pace of technological innovation and diffusion of e-commerce solutions and mobile commerce. We study the correlation between the composite index of consumer conditions and the level of participation in lifelong learning programmes in some Member States, based on secondary analysis of the data available at EU level,. The results confirm that the consumer`s situation is better in countries where the level of participation in lifelong learning programmes is higher. At the same time, however, the correlation is not linear. This shows that the consumer`s situation does not depend exclusively on formal continuing education but also other factors such as timeliness and severity of legal and institutional framework of consumer protection, the acquisition of knowledge through informal means, the requirement of different customers in different

Full Text Available This study examines the critical influence of advertising on consumer choice of telecommunication services in Nigeria. The advertisement played a key role in providing the consumers with product information. The study investigates the effect of marketing medium of telecommunication as a proxy for advertisement on preference of telecommunication services as a proxy for consumer choice in Nigeria. The Binary Logit Model (BLM and descriptive analytical frameworks are used to evaluate the statistical importance of advertisement, quality of services, income of the consumer, product’s self and related service charges for a consumer choice of telecommunication services through Wald test. The findings show that product’s self service charge and service quality are statistically significant for a consumer choice of telecommunication services in Nigeria at 1 percent significance level. And, related product’s service is statistically significant for a consumer choice of telecommunication services in Nigeria at 5 percent significance level. While advertisement and income of the consumer are statistically significant for a consumer choice of telecommunication services in Nigeria at 10 percent. The study concludes that advertisement is important for the choice of telecommunication services in Nigeria but having less impact. And, product’s self service charge and service quality are hugely significant for the choice of telecommunication services in Nigeria. Therefore, the sector of telecommunications needs more investment in advertisement so as to have telecommunications’ products information spread in order to stimulate the increase in demand for telecommunication services in Nigeria.

Consumer identification with store brands: Differences between consumers according to their brand loyalty

Directory of Open Access Journals (Sweden)

Natalia Rubio

2015-04-01

Full Text Available Retail management of store brands (SBs has focused on achieving positioning in value and creating associations of smart or expert shopping. The result is that value-conscious consumers and market mavens are the main targets of these brands. This study proposes and contrasts empirically a theoretical model of the effect of market mavenism and value consciousness on consumer identification with SBs. We also perform a multi-group analysis based on the consumer tendency to be loyal to the brands he or she buys. Consumers who are loyal to brands are very attractive segments for firms, due to the potential benefits these consumers represent in the long term, whereas consumers with little loyalty to brands can be an attractive segment for potential benefits in the short term. The results obtained in this study show differences between these two groups. For consumers who are loyal to brands, the results stress strong identification with the SB among the most value-conscious consumers, due fundamentally to their greater disagreement with the greater functional risk of these brands as compared to manufacturer brands and due to their greater conviction of the better price-quality ratio of SBs. In consumers with little brand loyalty, we find identification with the SB among the consumers with the greatest market mavenism, as a result of their greater perception of smart or expert shopping for these brands. Significant implications for management are derived from this study.

The upsurge in the demand for bottled water has prompted the interest of many manufacturers in the production of bottled water and very many water bottling companies are therefore involved in its production. These range from large scale multinational companies to medium scale business enterprises, institutional and government business investment companies as well as small scale entrepreneurs. There is however little information on the comparative quality of bottled water brands produced by different classes of water bottling companies in Nigeria. This study was undertaken to determine the bacteriological quality of brands of bottled water available to consumers in Ile-Ife. Forty-three samples of bottled water comprising of three batches each of thirteen bottled water brands and two batches of two brands were purchased and analyzed for total bacterial count, presence of coliform and the presence of other bacterial indicators of drinking water quality. Only 67.4% of the water samples representing the products of 10 companies or 66.7% of the brands had heterotrophic counts within the acceptable limits. Coliforms present in 100 ml of water were detected in 26.7% of the bottled water brands. Other indicator organisms detected included Staphylococci isolated from 27.9% of the samples (33.3% of the brands) and specifically Staphylococcus aureus found in four brands constituting 14% of the samples. Pseudomonas strains were consistently detected in consecutive batches of three brands of the water samples. Bottled water samples produced by the large scale multinational producers were of acceptable bacteriological quality unlike those produced by most small companies. There is need for a greater control of water bottling processes carried out by commercial bottled water producers in Nigeria.

River water is not only an indispensable source for irrigation but also plays a vital role for drinking water supply for most of the urban municipalities. Water from rivers is pumped at specific sites and after treatment at municipal water treatment plants supplied as domestic potable water supply. The present study was undertaken to assess the suitability of Gomti river water at Gaughat being used as the source of water supply for Lucknow city and to evaluate post-treatment potable water quality at the consumer end by monitoring the levels of inorganic pollutants (nitrate, nitrite, ammonium and phosphate) and heavy metals. Municipal water supply at Gaughat showed marked variations in the levels of p H (7.13-8.63) and electrical conductivity (375.66-571.67μS/cm). The amount of nitrate, nitrite, ammonium and phosphate was observed 26.25, 0.082, 6.9 and 1.82 mg/l respectively at Gaughat. Also, the levels of heavy metals in the municipal water source at Gaughat varied significantly for Fe (0.33-1.65 mg/l), Cu (0.077-0.108 mg/l), Cd (0.03-0.052 mg/l), Pb (0.68-0.96 mg/l) and Cr (0.036-0.065 mg/l). Water at the user end was also contaminated as the concentration of analysed inorganic pollutants and heavy metals were correspondingly higher than observed at the source. While comparing potable water at the user end of Lucknow municipality with the BIS (Drinking Water Specifications) and WHO standards for drinking water, the concentration of all studied heavy metals and other inorganic contaminants were much above the permissible levels, thus posing a serious threat to the public health.

Water Footprints and Sustainable Water Allocation

Full Text Available Water Footprint Assessment (WFA is a quickly growing research field. This Special Issue contains a selection of papers advancing the field or showing innovative applications. The first seven papers are geographic WFA studies, from an urban to a continental scale; the next five papers have a global scope; the final five papers focus on water sustainability from the business point of view. The collection of papers shows that the historical picture of a town relying on its hinterland for its supply of water and food is no longer true: the water footprint of urban consumers is global. It has become clear that wise water governance is no longer the exclusive domain of government, even though water is and will remain a public resource with government in a primary role. With most water being used for producing our food and other consumer goods, and with product supply chains becoming increasingly complex and global, there is a growing awareness that consumers, companies and investors also have a key role. The interest in sustainable water use grows quickly, in both civil society and business communities, but the poor state of transparency of companies regarding their direct and indirect water use implies that there is still a long way to go before we can expect that companies effectively contribute to making water footprints more sustainable at a relevant scale.

A pooled analysis of seven cross-sectional studies from Newfoundland and Labrador, Waterloo and Hamilton Regions, Ontario and Vancouver, East Kootenay and Northern Interior Regions, British Columbia (2001 to 2007) was performed to investigate the drinking water consumption patterns of Canadians and to identify factors associated with the volume of tap water consumed. The mean volume of tap water consumed was 1.2 L/day, with a large range (0.03 to 9.0 L/day). In-home water treatment and interactions between age and gender and age and bottled water use were significantly associated with the volume of tap water consumed in multivariable analyses. Approximately 25% (2,221/8,916) of participants were classified as bottled water users, meaning that 75% or more of their total daily drinking water intake was bottled. Approximately 48.6% (4,307/8,799) of participants used an in-home treatment method to treat their tap water for drinking purposes. This study provides a broader geographic perspective and more current estimates of Canadian water consumption patterns than previous studies. The identified factors associated with daily water consumption could be beneficial for risk assessors to identify individuals who may be at greater risk of waterborne illness.

Bhutada, Nilesh S; Rollins, Brent L

2015-01-01

Direct-to-consumer (DTC) advertising is still a controversial topic for pharmaceutical manufacturers' and researchers, and while numerous studies have examined the DTC phenomenon, little research has examined the effect of gender, particularly gender of the endorser and consumer. The objective of this research was to assess the impact of the endorser (celebrity vs. expert vs. non-celebrity) and gender - both gender of the endorser and gender of the consumer - on consumers' attitudes and behaviors in response to a print disease-specific direct-to-consumer advertisement. Using Qualtrics consumer panel, data were obtained for 514 US adults (age 18 years and above) who demonstrated at least minimal symptoms of depression and need for monitoring based on the Patient Health Questionnaire (PHQ) score. Data were analyzed using a 3 (Endorser Type: Celebrity/Expert/Non-Celebrity) × 2 (Endorser Gender: Male/Female) × 2 (Consumer Gender: Male/Female) full factorial between subjects multivariate analysis of variance (MANOVA) and necessary univariate analysis. Only the type of the endorser (celebrity vs. expert vs. non-celebrity) used in the ad had a significant main effect on the dependent variables. Further univariate analyses revealed that, of the several dependent variables, endorser type had a significant influence only on attitude towards the ad, attention paid to the ad, and endorser credibility, with gender being non-significant in all cases. Expert endorser generated significantly more favorable levels of attitude towards the ad, and endorser credibility compared to the non-celebrity endorser. Celebrity endorser attracted more consumer attention towards the ad and generated favorable endorser credibility perceptions compared to the non-celebrity endorser. However, celebrity and expert endorsers did not significantly differ from each other on the abovementioned ad effectiveness variables. Lastly, endorser gender and consumer gender did not have a significant influence

This research had two purposes. The first aim was to identify Iranian and Non-Iranian rice consumers based on demographic characteristics and examine difference of these features with buying behaviors. The second purpose of study was to investigate consumer's motivation to buy local rice in Iran. The sample were 1500 people (men and women). The data was collected by using questionnaire based on a face-to-face survey. Chi-square, confirmatory factor analysis, and multiple linear regression were applied to assess collected data by a questionnaire survey. Regarding Iranian local rice buyers, 884 people buy local rice. Chi-square test showed that there is a significant difference between gender, having children, and marital status in buying local rice. Habitual Iranian local rice buyers include: female (51%), people who are more than 45 years old (51%), people with children (63%), people who are living urban (61%), married people (48%) and individuals that their monthly income is between 321.5 and 625 Dollars (53%). Regarding non-Iranian rice buyers, 616 people buy it. Also there is a significant difference between gender, location, marital status, and income in buying local rice. For considering consumers motivation toward buying local rice the econometrical model is used. Model had three aspects including; quality aspects (taste, good appearance), economic aspects (price, convenience, consumer's ethnocentrism), and safety aspects (health, not using pesticides and environment protection) and seven subset. The results of analysis indicated that quality aspects, economic aspects and safety aspects have positive effects on buying Iranian local rice. Also, indicative variables including; taste, good appearance, price, convenience, consumer's ethnocentrism, health, not using pesticides and environment have significant effects on buying it.

Focused infrared lasers are widely used for micromanipulation and visualization of biological specimens. An inherent practical problem is that off-the-shelf commercial microscope objectives are designed for use with visible and not infrared wavelengths. Less aberration is introduced by water immersion objectives than by oil immersion ones, however, even water immersion objectives induce significant aberration. We present a simple method to reduce the spherical aberration induced by water immersion objectives, namely by tuning the correction collar of the objective to a value that is ∼ 10% lower than the physical thickness of the coverslip. This results in marked improvements in optical trapping strengths of up to 100% laterally and 600% axially from a standard microscope objective designed for use in the visible range. The results are generally valid for any water immersion objective with any numerical aperture

This 5-month study contains two parts: (1) to monitor the concentrations of 11 phthalate esters metabolites (PAEMs) and two beta-agonists in human urine samples collected from a small group of consented participants including 16 females and five males; and (2) to analyze the residues of phthalate esters (PAEs) and beta-agonists in various categories of drinking water consumed by the same group of subjects. Each category of human urine and drinking water had 183 samples of its own. The analytical results showed that nine PAEMs were detected in human urine and eight PAEs were detected in drinking water samples. It was found that average concentrations of PAEMs increased as the age increased, but no significant difference between sexes. Further, using the principal component analysis, the loadings of age effect were found to be two times greater than that of gender effect in terms of four DEHP metabolites. Regarding beta-agonists of concern (i.e., ractopamine and salbutamol), they were neither detected in human urine nor drinking water samples in this study. Copyright © 2014 Elsevier B.V.

Full Text Available Background: In recent years, water pipe smoking has been spread among adults especially in Asian African communities in the Middle East and Arabic countries. The aim of this study is determination of the nicotine dependence status and some related factors among women consumer in Bushehr. Material and Methods: 430 water pipe smoker women were examined in this cross-sectional study. Convenience and snowball sampling methods were used to collect data. After data collection, data were analyzed by SPSS software with using appropriate statistical tests. Results: In this study, 43.4% (N= 186 of women had moderate nicotine dependency. The overall mean and standard deviation score for nicotine dependence were 40.71±12.63. In this study, consumer’s education (p=0.004 and job (p=0.015, husband’s education (p=0.003, and job (p=0.043, history of water pipe smoking (p=0.000, intention to quit (p=0.021, and type of tobacco (p=0.003, significantly associated with nicotine dependence. Logit regression results showed that husband 's education level, age at onset of water pipe consuming and intention to quit water pipe explain nicotine dependence. Conclusion: Nicotine dependence among almost half of the consumer women was in average level and it is essential to design educational interventions for low socio - economic individuals particularly in teens and young people that this behavior has not institutionalized yet. Also for people who have no intention of quit water pipe, at first, we provide the conditions for their quitting through empowerment process and then encourage them to quit water pipe.

Meat is a good source of proteins and irons, yet its consumption has been associated with unfavorable cardiovascular effects. Whether this applies to all types of meat is unclear. We thus aimed to appraise the impact of water buffalo meat consumption on cardiovascular risk profile with an observational longitudinal study. Several important cardiovascular risk features were appraised at baseline and at 12-month follow-up in 300 adult subjects divided in groups: recent consumers of water buffalo meat vs subjects who had never consumed water buffalo meat. In addition, long-standing consumers of water buffalo meat were evaluated. Age, gender, height, body weight, and the remaining diet (with the exception of cow meat consumption) were similar across groups. From baseline to follow-up, recent consumers of water buffalo meat change their intake of water buffalo meat from none to 600+/-107 g per week (Pconsumption from 504+/-104 to 4+/-28 (PConsumption of buffalo meat seems to be associated with several beneficial effects on cardiovascular risk profile. Awaiting further randomized clinical trials, this study suggests that a larger consumption of water buffalo meat could confer significant cardiovascular benefits, while continuing to provide a substantial proportion of the recommended daily allowance of protein.

Full Text Available Indonesia is a large market for consumer products targeting youth consumers, with populations of more than 70 million young inhabitants and market size of USD 155 billion. The large size of this potential market attracts foreign products with globallyrecognized brands to enter the Indonesian market. The objective of this study is to explain the purchase intention of youth consumers toward a particular brand of soft drink with global penetration by their perceptions and ethnocentrism. This study obtained response from 156 youths in Greater Jakarta, Indonesia. The resulting data was analyzed using structural equation modeling with LISREL software package. The study found that consumer ethnocentrism decreases purchase intention, both directly and indirectly through brand image. Contrary to the hypothesis, consumer ethnocentrism does not influence corporate image of the global firm, which significantly influences brand image but only slightly impacts purchase intentions directly.

In 1978, a ground breaking paper titled, "Feasibility of Rocket Propellant Production on Mars" by Ash, Dowler, and Varsi discussed how ascent propellants could be manufactured on the Mars surface from carbon dioxide collected from the atmosphere to reduce launch mass. Since then, the concept of making mission critical consumables such as propellants, fuel cell reactants, and life support consumables from local resources, commonly known as In-Situ Resource Utilization (ISRU), for robotic and human missions to Mars has been studied many times. In the late 1990's, NASA initiated a series of Mars Human Design Reference Missions (DRMs), the first of which was released in 1997. These studies primarily focused on evaluating the impact of making propellants on Mars for crew ascent to Mars orbit, but creating large caches of life support consumables (water & oxygen) as a backup for regenerative life support systems for long-duration surface stays (>500 days) was also considered in Mars DRM 3.0. Until science data from the Mars Odyssey orbiter and subsequent robotic missions revealed that water may be widely accessable across the surface of Mars, prior Mars ISRU studies were limited to processing Mars atmospheric resources (carbon dioxide, nitrogen, argon, oxygen, and water vapor). In December 2007, NASA completed the Mars Human Design Reference Architecture (DRA) 5.0 study which considered water on Mars as a potential resource for the first time in a human mission architecture. While knowledge of both water resources on Mars and the hardware required to excavate and extract the water were very preliminary, the study concluded that a significant reduction in mass and significant enhancements to the mission architecture were possible if Mars water resources were utilized. Two subsequent Mars ISRU studies aimed at reexamining ISRU technologies, processing options, and advancements in the state-of-the-art since 2007 and to better understand the volume and packaging associated

How More Data About Direct and Virtual Water Use Could Help People Understand Their Water Footprints and Save More Water

Science.gov (United States)

Madel, R.; Olson-Sawyer, K.; Hanlon, P.; Rabin, K.

2017-12-01

Attari (2014) has shown through online surveys that Americans underestimate their water use, don't know what their water footprint is and don't know how much water it takes to produce food. The more people know about their water use, the better decisions they are capable of making and the more likely they are to conserve, which is especially important during periods of water stress. To increase awareness and help people decrease their daily water use, GRACE Communications Foundation created a Water Footprint Calculator [watercalculator.org] using US-oriented data and presented in US units in both English and Spanish. The calculator is based on direct water use data as well as the water consumed to create food, consumer goods and energy (also known as virtual or indirect water use). We learned that there is a lack of comparably-scaled, consumer-level virtual water research available. The direct use data gathered for the calculator came primarily from a study of residential water use in the US by Mayer et al. (1999), who conducted surveys of households in different US cities and averaged data for both inside and outside the home. The indirect use data came from various sources including the US government (USGS, EPA, EIA, NREL, Energy Star, etc.), the Water Footprint Network and the UN FAO. Much of the indirect use data was aggregated at a national level or came from combinations of various data sets. For all users, the food category accounts for the largest part of their water footprints. Gathering data of comparable scale at a personal consumption level proved to be a challenging exercise and provided several takeaways. While there is recent residential direct water use data at a consumer level, there is a lack of data at the personal, consumer level about indirect water use in manufacturing, energy production and agriculture. Because of this, we had to use national averages and generalized calculations. The resulting tool gives people a sense of the impacts of

Influence of alkalinity, hardness and dissolved solids on drinking water taste: A case study of consumer satisfaction.

Lou, Jie-Chung; Lee, Wei-Li; Han, Jia-Yun

2007-01-01

Two surveys of consumer satisfaction with drinking water conducted by Taiwan Water Supply Corp. are presented in this study. The study results show that although a lot of money was invested to modify traditional treatment processes, over 60% of local residents still avoided drinking tap water. Over half of the respondents felt that sample TT (from the traditional treatment process) was not a good drinking water, whether in the first or second survey, whereas almost 60% of respondents felt that samples PA, PB, CCL and CT (from advanced treatment processes) were good to drink. For all drinking water samples, respondent satisfaction with a sample primarily depended on it having no unpleasant flavors. Taiwan Environmental Protection Administration plans to revise the drinking water quality standards for TH and TDS in the near future. The new standards require a lower TH concentration (from currently 400mg/L (as CaCO(3)) to 150mg/L (as CaCO(3))), and a lower TDS maximum admissible concentration from the current guideline of 600 to 250mg/L. Therefore, this study also evaluated the impacts on drinking water tastes caused by variations in TH and TDS concentrations, and assessed the need to issue more strict drinking water quality standards for TH and TDS. The research results showed that most respondents could not tell the difference in water taste among water samples with different TDS, TH and alkalinity. Furthermore, hardness was found to be inversely associated with cardiovascular diseases and cancers, and complying with more strict standards would lead most water facilities to invest billions of dollars to upgrade their treatment processes. Consequently, in terms of drinking water tastes alone, this study suggested that Taiwan Environmental Protection Administration should conduct more thorough reviews of the scientific literature that provides the rationale for setting standards and reconsider if it is necessary to revise drinking water quality standards for TH and

2014-12-01

PFAS are man-made compounds that are highly spread in the environment. Human dietary exposure to such contaminants is of high concern as they may accumulate in the food chain. Different studies already demonstrated the importance of the fish consumption in the dietary exposure of these molecules and the potential increase of internal doses of PFAS following the consumption of PFAS. However, so far few study aimed to study the link between the consumption of fresh water fishes and the internal exposure to PFAS. Objectives of this study were (i) to estimate the internal exposure of populations that are potentially high consumers of fresh water fishes and (ii) to determine whether the consumption of fish caught from fresh water is a significant determinant of the internal exposure of PFAS. In this work, a large sample of adult freshwater anglers from the French metropolitan population (478 individuals) was constituted randomly from participants lists of anglers associations. Questionnaires provided social and demographic information and diet information for each subject. In addition, analyses of blood serum samples provided the internal concentration of 14 PFAS. The survey design allowed to extrapolate the data obtained on the 478 individuals to the freshwater angler population. Descriptive data regarding internal levels of PFAS were discussed at the population level, whereas identification of the determinants were done at the 478 individuals level as sufficient contrast was required in terms of fresh water fish consumption. Only molecules for which the detection frequency were above 80% in blood were considered, i.e., PFOS, PFOA, PFHxS, PFNA, PFHpS, and PFDA. Distribution profiles showed log-normal distribution and PFOS and PFOA were the main contributors of the PFAS sum. For PFOS, the results obtained on the 478 individuals showed that upper percentiles were higher as compared to upper percentiles obtained on occidental general population. This confirmed an over

Cooling water requirements and nuclear power plants

International Nuclear Information System (INIS)

Rao, T.S.

2010-01-01

Indian nuclear power programme is poised to scuttle the energy crisis of our time by proposing joint ventures for large power plants. Large fossil/nuclear power plants (NPPs) rely upon water for cooling and are therefore located near coastal areas. The amount of water a power station uses and consumes depends on the cooling technology used. Depending on the cooling technology utilized, per megawatt existing NPPs use and consume more water (by a factor of 1.25) than power stations using other fuel sources. In this context the distinction between 'use' and 'consume' of water is important. All power stations do consume some of the water they use; this is generally lost as evaporation. Cooling systems are basically of two types; Closed cycle and Once-through, of the two systems, the closed cycle uses about 2-3% of the water volumes used by the once-through system. Generally, water used for power plant cooling is chemically altered for purposes of extending the useful life of equipment and to ensure efficient operation. The used chemicals effluent will be added to the cooling water discharge. Thus water quality impacts on power plants vary significantly, from one electricity generating technology to another. In light of massive expansion of nuclear power programme there is a need to develop new ecofriendly cooling water technologies. Seawater cooling towers (SCT) could be a viable option for power plants. SCTs can be utilized with the proper selection of materials, coatings and can achieve long service life. Among the concerns raised about the development of a nuclear power industry, the amount of water consumed by nuclear power plants compared with other power stations is of relevance in light of the warming surface seawater temperatures. A 1000 MW power plant uses per day ∼800 ML/MW in once through cooling system; while SCT use 27 ML/MW.

Directory of Open Access Journals (Sweden)

Ana Castillo-Martinez

2014-05-01

Full Text Available A significant decrease in water consumption has been achieved in recent years thanks to different campaigns run by different institutions in Spain. However, most citizens do not have a very clear idea about whether or not they are efficiently using water. To solve this situation, this paper aims is to develop two water labels in order to improve the current water billing. These water labels evaluate the total water consumption and the domestic hot water consumption. To make the tags, several research studies were tackled for establishing consumer trends and behavior patterns. Furthermore, a survey and data collection were conducted to obtain updated values to validate information obtained from previous studies. The result are two water labels that establish six different levels to graphically show the efficiency, and they also include a comparison with the average consumption by customers of the same province. To ensure that the benefits of this evaluation are available to citizens, its inclusion on the water bill is proposed.

2016-01-01

To examine the potential impact of California SB 1413, which required school districts to provide free, fresh drinking water during mealtimes in food service areas by July 1, 2011, on greater water consumption among California adolescents. Data were drawn from the 2012 and 2013 state-representative California Health Interview Survey. A total of 2,665 adolescents aged 12-17 years were interviewed regarding their water consumption and availability of free water during lunchtime at their school. Three-fourths reported that their school provided free water at lunchtime, mainly via fountains. In a multivariate model that controlled for age, gender, income, race/ethnicity, body mass index, and school type, adolescents in schools that provided free water consumed significantly more water than adolescents who reported that water was not available, bivariate (standard error) = .67 (.28), p = .02. School water access did not significantly vary across the 2 years. Lunchtime school water availability was related to water consumption, but a quarter of adolescents reported that their school did not provide free water at lunch. Future research should explore what supports and inducements might facilitate provision of drinking water during school mealtimes. Copyright © 2016 Society for Adolescent Health and Medicine.

Malodorous volatile organic sulfur compounds: Sources, sinks and significance in inland waters.

Science.gov (United States)

Watson, Susan B; Jüttner, Friedrich

2017-03-01

Volatile Organic Sulfur Compounds (VOSCs) are instrumental in global S-cycling and greenhouse gas production. VOSCs occur across a diversity of inland waters, and with widespread eutrophication and climate change, are increasingly linked with malodours in organic-rich waterbodies and drinking-water supplies. Compared with marine systems, the role of VOSCs in biogeochemical processes is far less well characterized for inland waters, and often involves different physicochemical and biological processes. This review provides an updated synthesis of VOSCs in inland waters, focusing on compounds known to cause malodours. We examine the major limnological and biochemical processes involved in the formation and degradation of alkylthiols, dialkylsulfides, dialkylpolysulfides, and other organosulfur compounds under different oxygen, salinity and mixing regimes, and key phototropic and heterotrophic microbial producers and degraders (bacteria, cyanobacteria, and algae) in these environs. The data show VOSC levels which vary significantly, sometimes far exceeding human odor thresholds, generated by a diversity of biota, biochemical pathways, enzymes and precursors. We also draw attention to major issues in sampling and analytical artifacts which bias and preclude comparisons among studies, and highlight significant knowledge gaps that need addressing with careful, appropriate methods to provide a more robust understanding of the potential effects of continued global development.

A risk assessment for consumers of mourning doves

International Nuclear Information System (INIS)

Burger, J.; Kennamer, R.A.; Brisbin, I.L. Jr.; Gochfeld, M.

1998-01-01

Recreational and subsistence hunters and anglers consume a wide range of species, including birds, mammals, fish and shellfish, some of which represent significant exposure pathways for environmental toxic agents. This study focuses on the Department of Energy's (DOE's) Savannah River Site (SRS), a former nuclear weapons production facility in South Carolina. The potential risk of contaminant intake from consuming mourning doves (Zenaida macroura), the most popular United States game bird, was examined under various risk scenarios. For all of these scenarios the authors used the mean tissue concentration of six metals (lead, mercury, cadmium, selenium, chromium, manganese) and radiocesium, in doves collected on and near SRS. They also estimated risk to a child consuming doves that had the maximum contaminant level. The authors used the cancer slope factor for radiocesium, the Environmental Protection Agencies Uptake/Biokinetic model for lead, and published reference doses for the other metals. As a result of their risk assessments they recommend management of water levels in contaminated reservoirs so that lake bed sediments are not exposed to use by gamebirds and other terrestrial wildlife. Particularly, measures should be taken to insure that the hunting public does not h ave access to such a site. Their data also indicate that doves on popular hunting areas are exposed to excess lead, suggesting that banning lead shot for doves, as has been done for waterfowl, is desirable

Full Text Available This contribution is a follow-up to the topic of consumer behavior which is analyzed from the economic theory perspective on microeconomic as well as a macroeconomic level. The main objective of the article is to reveal the structure of college students’ consumer basket determined according to disposable income and its changes. In this article, the methodology of a consumer basket was used. The division of it was done by Czech Statistical Office to calculate the inflation rate in the environment of the Czech Republic. In this article, the analysis of college students’ consumer basket was done. The pressure on having a higher qualification in tertiary education is a typical trend across Europe, which is also one of strategic goals of EU Strategy 2020 and its concept. There is clear evidence of a growing segment of college students that represents a significant demand group on the product and service market. The knowledge of their consumer habits is definitely beneficial for companies regarding their competitive advantage and reaching higher incomes from the products offered. The market product consumption is dependent on the total disposable income mainly. That is fundamentally dependent on hours of paid work or other fund contributions. The current disposable income shows the differences regarding consumption expenditures of a consumer basket and its various categories. A lower disposable income is typical for flowing the highest consumer expenditures from class 1 (Food and non-alcoholic beverages to class 4 (Housing, water, electricity, gas and other fuels of a higher disposal income. If the current disposable income of college students increases, there would be higher consumption expenditures regarding classes 9, 3 and 5 (Recreation and culture; Clothing and footwear; Furnishings, household equipment and routine household maintenance. On the contrary, a lower disposable income would mean lower expenditures regarding classes 3, 2 and 9

Direct-to-consumer (DTC) advertising of predictive genetic tests (PGTs) has added a new dimension to health advertising. This study used an online survey based on the health belief model framework to examine and more fully understand consumers' responses and behavioral intentions in response to a PGT DTC advertisement. Overall, consumers reported moderate intentions to talk with their doctor and seek more information about PGTs after advertisement exposure, though consumers did not seem ready to take the advertised test or engage in active information search. Those who perceived greater threat from the disease, however, had significantly greater behavioral intentions and information search behavior.

An Agent Based Model of Household Water Use

Directory of Open Access Journals (Sweden)

Clinton J. Andrews

2013-07-01

Full Text Available Households consume a significant fraction of total potable water production. Strategies to improve the efficiency of water use tend to emphasize technological interventions to reduce or shift water demand. Behavioral water use reduction strategies can also play an important role, but a flexible framework for exploring the “what-ifs” has not been available. This paper introduces such a framework, presenting an agent-based model of household water-consuming behavior. The model simulates hourly water-using activities of household members within a rich technological and behavioral context, calibrated with appropriate data. Illustrative experiments compare the resulting water usage of U.S. and Dutch households and their associated water-using technologies, different household types (singles, families with children, and retired couples, different water metering regimes, and educational campaigns. All else equal, Dutch and metered households use less water. Retired households use more water because they are more often at home. Water-saving educational campaigns are effective for the part of the population that is receptive. Important interactions among these factors, both technological and behavioral, highlight the value of this framework for integrated analysis of the human-technology-water system.

Exploring Perceptions and Behaviors about Drinking Water in Australia and New Zealand: Is It Risky to Drink Water, When and Why?

Directory of Open Access Journals (Sweden)

Andrea Crampton

2016-02-01

Full Text Available Consumers in most developed countries, including Australia and New Zealand, presume their drinking water is safe. How social perceptions about drinking water are formed, however, remains inadequately explored in the research literature. This research contributes exploratory insights by examining factors that affect consumer perceptions and behaviors. Individual perceptions of drinking water quality and actions undertaken to mitigate perceived risks were collected during 183 face-to-face interviews conducted at six research sites. Qualitative thematic analysis revealed the majority did not consider drinking water a “risky” activity, trusted water management authorities to manage all safety issues and believed self-evaluation of drinking water’s taste and appearance were sufficient measures to ensure safe consumption. Quantitatively, significant relationships emerged between water quality perceptions and sex, employment status, drinking water treatment and trust in government to provide safe water. Expert advice was rarely sought, even by those who believed drinking tap water posed some health risks. Generational differences emerged in media usage for drinking water advice. Finally, precautionary measures taken at home and abroad often failed to meet national drinking water guidelines. Three major conclusions are drawn: a. broad lack of awareness exists about the most suitable and safe water treatment activities, as well as risks posed; b. health literacy and interest may be improved through greater consumer involvement in watershed management; and c. development of health campaigns that clearly communicate drinking water safety messages in a timely, relevant and easily understandable fashion may help mitigate actual risks and dispel myths.

Hot water reticulation

Energy Technology Data Exchange (ETDEWEB)

Fellows, S. K.

1977-10-15

Hot water reticulation (district heating) is an established method of energy supply within cities in many countries. It is based on the fact that heat can often be obtained cheaply in bulk, and that the resultant savings can, in suitable circumstances, justify the investment in a reticulation network of insulated pipes to distribute the heat to many consumers in the form of hot water or occasionally steam. The heat can be used by domestic, commercial, and industrial consumers for space heating and water heating, and by industries for process heat. The costs of supplying domestic consumers can be determined by considering an average residential area, but industrial and commercial consumers are so varied in their requirements that every proposal must be treated independently. Fixed costs, variable costs, total costs, and demand and resource constraints are discussed.

Low water FGD technologies

NONE

2012-11-15

Conventional flue gas desulphurisation (FGD) systems require large supplies of water. Technologies which reduce water usage are becoming more important with the large number of FGD systems being installed in response to ever tightening emission regulations. Reducing water loss is particularly important in arid regions of the world. This report reviews commercial and near commercial low water FGD processes for coal-fired power plants, including dry, semi-dry and multi-pollutant technologies. Wet scrubbers, the most widely deployed FGD technology, account for around 10–15% of the water losses in power plants with water cooling systems. This figure is considerably higher when dry/air cooling systems are employed. The evaporative water losses can be reduced by some 40–50% when the flue gas is cooled before it enters the wet scrubber, a common practice in Europe and Japan. Technologies are under development to capture over 20% of the water in the flue gas exiting the wet scrubber, enabling the power plant to become a water supplier instead of a consumer. The semi-dry spray dry scrubbers and circulating dry scrubbers consume some 60% less water than conventional wet scrubbers. The commercial dry sorbent injection processes have the lowest water consumption, consuming no water, or a minimal amount if the sorbent needs hydrating or the flue gas is humidified to improve performance. Commercial multi-pollutant systems are available that consume no water.

Consumer's inflation expectations in Brazil

Directory of Open Access Journals (Sweden)

Fernando Ormonde Teixeira

Full Text Available Abstract This paper investigates what are the main components of consumer's inflation expectations. We combine the FGV's Consumer Survey with the indices of inflation (IPCA and government regulated prices, professional forecasts disclosed in the Focus report, and media data which we crawl from one of the biggest and most important Brazilian newspapers, Folha de São Paulo, to determine what factors are responsible for and improve consumer's forecast accuracy. We found gender, age and city of residence as major elements when analyzing micro-data. Aggregate data shows the past inflation as an important trigger in the formation of consumers' expectations and professional forecasts as negligible. Moreover, the media plays a significant role, accounting not only for the expectations' formation but for a better understanding of actual inflation as well.

2010-07-01

Digital photographs of pork chops varying systematically in appearance were presented to 716 Taiwanese consumers in a study that aimed to identify the most important characteristics of fresh pork which determine consumer choice in Taiwan. Relationships between consumer segmentation in choice and socio-demographic and cultural differences were also investigated. Colour and fat cover were the most frequently chosen of the four characteristics studied. Dark red colour was preferred by 64% of consumers and lean fat cover by 44%. Marbling and drip were less important in the decision making process being used by less than a half of consumers. The four preference-based clusters of consumers showed no correlation with socio-demographic-based consumer clusters, but did show significant links with possession of a refrigerator, age at which schooling was completed, liking pork for its price and gender of consumer.

The significance of Campylobacter jejuni infection in poultry: a review.

Science.gov (United States)

Shane, S M

1992-01-01

Campylobacter is a significant cause of enterocolitis in consumers of undercooked poultry meat. Campylobacter jejuni is the most significant of the three thermophilic Campylobacter species, and is responsible for intestinal colonization in poultry and food-borne enteritis in humans. Generally, C. jejuni is apathogenic in poultry, although newly hatched chicks and turkeys may develop a transient diarrhoea following infection. Modern intensive poultry production favours the introduction of infection into commercial growing units, resulting in intestinal colonization during the second to fourth weeks inclusive. Routes of infection include contaminated fomites, infected water supply, rodents, insects, and free-living birds. Vertical transmission is considered unlikely. Contamination of poultry meat is enhanced by deficiencies in transport and processing of broilers and turkeys. Scalding, defeathering and evisceration represent the significant points of cross-contamination during processing. Epidemiological correlation has been established between consumption of contaminated chicken and outbreaks of human campylobacteriosis. Amelioration of infection by application of improved standards of hygiene and decontamination is possible in the context of commercial poultry production. Improvement in washing of carcasses, and the application of chemical disinfectants and gamma irradiation have the potential to reduce the prevalence of C. jejuni contamination in poultry meat. These innovations, together with improved storage and handling of meat products, will reduce the risk of campylobacteriosis to consumers.

The combined interaction of epidemiology, environmental exposure, dietary habits, and genetic factors causes kidney stone disease (KSD), a common public health problem worldwide. Because a high water intake (>3 L daily) is widely recommended by physicians to prevent KSD, the present study evaluated whether the quantity of water that people consume daily is associated with KSD and whether the quality of drinking water has any effect on disease prevalence. Information regarding residential address, daily volume of water consumption, and source of drinking water was collected from 1,266 patients with kidney stones in West Bengal, India. Drinking water was collected by use of proper methods from case (high stone prevalence) and control (zero stone prevalence) areas thrice yearly. Water samples were analyzed for pH, alkalinity, hardness, total dissolved solutes, electrical conductivity, and salinity. Average values of the studied parameters were compared to determine if there were any statistically significant differences between the case and control areas. We observed that as many as 53.6% of the patients consumed water daily. Analysis of drinking water samples from case and control areas, however, did not show any statistically significant alterations in the studied parameters. All water samples were found to be suitable for consumption. It is not the quality of water, rather the quantity of water consumed that matters most in the occurrence of KSD.

Using Water Footprints to Identify Alternatives for Conserving Local Water Resources in California

Directory of Open Access Journals (Sweden)

D. L. Marrin

2016-11-01

Full Text Available As a management tool for addressing water consumption issues, footprints have become increasingly utilized on scales ranging from global to personal. A question posed by this paper is whether water footprint data that are routinely compiled for particular regions may be used to assess the effectiveness of actions taken by local residents to conserve local water resources. The current California drought has affected an agriculturally productive region with large population centers that consume a portion of the locally produced food, and the state’s arid climate demands a large volume of blue water as irrigation from its dwindling surface and ground water resources. Although California exports most of its food products, enough is consumed within the state so that residents shifting their food choices and/or habits could save as much or more local blue water as their reduction of household or office water use. One of those shifts is reducing the intake of animal-based products that require the most water of any food group on both a gravimetric and caloric basis. Another shift is reducing food waste, which represents a shared responsibility among consumers and retailers, however, consumer preferences ultimately drive much of this waste.

Getting into hot water Problematizing hot water service demand: The case of Old Cairo

Science.gov (United States)

Culhane, Thomas Henry

-help strategies, the greater flexibility they provide may lead to superior long-term outcomes in a time of uncertain and rising energy and commodities prices and an increasing availability of new, less expensive, increasingly modular, and more efficient technologies that are easier for individual households to install and use, especially if the State or non-governmental institutions can provide implementation support. The descriptive statistics and the multivariate models obtained through the analysis of the data gathered in the surveys show that while purchase price and running costs for dedicated water heating systems are considerations for families desiring hot water, the infrastructural demands of modern appliances vis a vis a consumer's given built environment and the historical/cultural legacy of the consumer's past hot water choices and practices are often more important determinants of the kind of water heating used and desired today. Our study shows, for example, that while higher income is associated with owning a water heater in a simple model with few explanatory variables (Model 3) it's significance disappears when controlling for Ethnicity and infrastructural elements (Model 1). This might suggest that while within communities there is a point at which making more money implies a shift to consumer "modernity", overall the availability of more money in these neighborhoods as a whole doesn't guarantee that the utility promised by modern appliances will be realized. A similar point can be made about formal education levels, which appear insignificant in our models. Policy that aimed merely at sending more kids to school would not address the great deficiencies that many Egyptian schools are noted for. There is no guarantee that merely expanding Egypt's "universal education" policy to include children who have fallen through the cracks would help increase consumer awareness or consumer choice. On the other hand both water availability and presence of hot water pipes, as

Medicalization, markets and consumers.

Conrad, Peter; Leiter, Valerie

2004-01-01

This paper examines the impact of changes in the medical marketplace on medicalization in U.S. society. Using four cases (Viagra, Paxil, human growth hormone and in vitro fertilization), we focus on two aspects of the changing medical marketplace: the role of direct-to-consumer advertising of prescription drugs and the emergence of private medical markets. We demonstrate how consumers and pharmaceutical corporations contribute to medicalization, with physicians, insurance coverage, and changes in regulatory practices playing facilitating roles. In some cases, insurers attempt to counteract medicalization by restricting access. We distinguish mediated and private medical markets, each characterized by differing relationships with corporations, insurers, consumers, and physicians. In the changing medical environment, with medical markets as intervening factors, corporations and insurers are becoming more significant determinants in the medicalization process.

Camps, Guido; Mars, Monica; de Graaf, Cees; Smeets, Paul A M

2017-07-01

The process of gastric emptying determines how fast gastric content is delivered to the small intestine. It has been shown that solids empty slower than liquids and that a blended soup empties slower than the same soup as broth and chunks, due to the liquid fraction emptying more quickly. This process of 'gastric sieving' has not been investigated for liquid foods. To determine whether gastric sieving of water can also occur for liquid foods. Two groups of men participated in a parallel design (n=15, age 22.6±2.4y, BMI 22.6±1.8kg/m 2 , and n=19, age 22.2±2.5y, BMI 21.8±1.5kg/m 2 ) and consumed an isocaloric shake (2093kJ, CARBOHYDRATES: 71g, FAT: 18g, PROTEIN: 34g), either in a 500-mL version (MIXED) or as a 150-mL shake followed by 350mL water (SEPARATE). Participants provided appetite ratings and were scanned using MRI to determine gastric emptying rate and volume at three time-points within 35min post ingestion. Gastric emptying the percentage emptied in 35min was significantly smaller for MIXED (29±19%) than for SEPARATE (57±11%, p<0.001). In the present study we show that gastric sieving can occur for liquid foods; water is able to drain from the stomach while a layer of nutrient rich liquid is retained. In indirect gastric emptying measurements, the behavior of labelling agents may be affected by the layering and confound emptying measurements. Copyright © 2017 Elsevier Inc. All rights reserved.

Evacuation of performance and significant chemical constituents and by products in drinking water treatment

International Nuclear Information System (INIS)

Jamrah, I. A.

1999-01-01

Drinking water treatment is a task that comprises of several processes that eventually lead to the addition of chemicals to achieve the objectives of treatment. This study was conducted to assess treatment performance, explain the presence of significant chemical species in water, and investigate the interactions and chemical by-products that are formed during the course of treatment. Grab water samples were collected on a regular basis from the influent and effluent of Zai water treatment plant. Chemical analysis were conducted to determine the concentrations of various chemical species of interest. Turbidity, temperature, and pH of the samples were also measured. The study concluded that Zai Water Treatment Plant produces potable drinking water in accordance with Jordanian Standards. The use of treatment chemical resulted in an increase in the concentrations of certain materials, such as manganese, aluminum, and sulfate. The turbidity of the raw water and the TOC of the samples were positively correlated, and the treatment results in approximately 20% TOC reduction, which demonstrates that the measures used for the control of TOC (carbon adsorption and permanganate pre-oxidation), are not very effective. The study also showed that the TOC content of our raw water samples and the concentration of tribalomethanes resulting after disinfection were positively correlated, and that bromoform was the dominant component. Also chloroform was the minor component of tribalomethanes formed during treatment. Positive correlation between the total concentration of tribalomethanes in water and the chlorine dose used for disinfection was also observed, and the total concentration of tribalomethanes increased with temperature. The formation of tribalomethanes was enhanced as the pH of water increased and as the concentration of bromide ion in raw water became significant. (author). 25 refs., 14 figs.1 table

Water use by the electricity sector represents a significant portion of the United States water budget (41% of total freshwater withdrawals; 3% consumed). Sustainable management of water resources necessitates an accurate accounting of all water demands, including water use for generation of electricity. Since 1985, the Department of Energy (DOE) Energy Information Administration (EIA) has collected self-reported data on water consumption and withdrawals from individual power generators. These data represent the only annual collection of water consumption and withdrawals by the electricity sector. Here, we compile publically available information into a comprehensive database and then calculate water withdrawals and consumptive use for power plants in the US. In effect, we evaluate the quality of water use data reported by EIA for the year 2008. Significant differences between reported and calculated water data are evident, yet no consistent reason for the discrepancies emerges. (letter)

Supplying piped water intermittently is a common practice throughout the world that increases the risk of microbial contamination through multiple mechanisms. Converting an intermittent supply to a continuous supply has the potential to improve the quality of water delivered to consumers. To understand the effects of this upgrade on water quality, we tested samples from reservoirs, consumer taps, and drinking water provided by households (e.g. from storage containers) from an intermittent and continuous supply in Hubli-Dharwad, India, over one year. Water samples were tested for total coliform, Escherichia coli, turbidity, free chlorine, and combined chlorine. While water quality was similar at service reservoirs supplying the continuous and intermittent sections of the network, indicator bacteria were detected more frequently and at higher concentrations in samples from taps supplied intermittently compared to those supplied continuously (p supply, with 0.7% of tap samples positive compared to 31.7% of intermittent water supply tap samples positive for E. coli. In samples from both continuously and intermittently supplied taps, higher concentrations of total coliform were measured after rainfall events. While source water quality declined slightly during the rainy season, only tap water from intermittent supply had significantly more indicator bacteria throughout the rainy season compared to the dry season. Drinking water samples provided by households in both continuous and intermittent supplies had higher concentrations of indicator bacteria than samples collected directly from taps. Most households with continuous supply continued to store water for drinking, resulting in re-contamination, which may reduce the benefits to water quality of converting to continuous supply.

Although small, rural water supplies may present elevated microbial risks to consumers in some settings, characterizing exposures through representative point-of-consumption sampling is logistically challenging. In order to evaluate the usefulness of consumer self-reported data in predicting measured water quality and risk factors for contamination, we compared matched consumer interview data with point-of-survey, household water quality and pressure data for 910 households served by 14 small water systems in rural Alabama. Participating households completed one survey that included detailed feedback on two key areas of water service conditions: delivery conditions (intermittent service and low water pressure) and general aesthetic characteristics (taste, odor and color), providing five condition values. Microbial water samples were taken at the point-of-use (from kitchen faucets) and as-delivered from the distribution network (from outside flame-sterilized taps, if available), where pressure was also measured. Water samples were analyzed for free and total chlorine, pH, turbidity, and presence of total coliforms and Escherichia coli. Of the 910 households surveyed, 35% of participants reported experiencing low water pressure, 15% reported intermittent service, and almost 20% reported aesthetic problems (taste, odor or color). Consumer-reported low pressure was associated with lower gauge-measured pressure at taps. While total coliforms (TC) were detected in 17% of outside tap samples and 12% of samples from kitchen faucets, no reported water service conditions or aesthetic characteristics were associated with presence of TC. We conclude that consumer-reported data were of limited utility in predicting potential microbial risks associated with small water supplies in this setting, although consumer feedback on low pressure-a risk factor for contamination-may be relatively reliable and therefore useful in future monitoring efforts.

Full Text Available Hotel sector causes significant environmental stress in both natural and built up areas due to their consumption of water and energy. In addition, the production of large volumes of liquid and solid waste results in a significant environmental footprint. The use of water and energy by hotels is strongly linked (e.g. energy is consumed for hot water, operation of the pool, preparation of meals, etc. and usually referred to as the water – energy nexus. Thus, for big consumers like hotels, water and energy consumption should be addressed collectively as water-saving measures can lead to a reduction in energy consumption. The aim of this study is to assess the environmental performance of mid-sized hotel units by analyzing and quantifying their use of water. An analysis using a two-step approach was made of 8 accommodation facilities located on Samos Island, Greece: (i a mapping of water use by adopting an end-use approach, and then (ii an assessment of saving practices using three main criteria: savings, cost of investment and payback time. The preliminary results indicate that for small sized lodging units, water consumed inside the guest rooms accounts for the majority of all the water used and low-cost water saving measures and actions can reduce the pressure on water resources without disturbing guests, while increasing the financial profitability of a hotel.

Full Text Available Jeju water is the groundwater of Jeju Island, a volcanic island located in Republic of Korea. We investigated whether Jeju water improved glycemic control in patients with diabetes. This was a 12-week single-center, double-blind, randomized, and controlled trial. The subjects daily drank a liter of one of three kinds of water: two Jeju waters (S1 and S2 and Seoul tap water (SS. The primary outcome was the proportion of patients in the per-protocol (PP population achieving glycated hemoglobin (HbA1c < 7.0% at week 12. In total, 196 patients were randomized and analyzed in the intention-to-treat (ITT population (66 consuming S1, 63 consuming S2, and 67 consuming SS; 146 patients were considered in the PP population. There were no significant differences in the primary outcomes of the groups consuming S1, S2, or SS. However, the percentage of patients achieving HbA1c < 8% was significantly higher in the S2 group than in the SS group. In the ITT population, the 12-week HbA1c and fructosamine levels were lower in the S1 group than in the SS group and the 4-, 8-, and 12-week fructosamine levels were lower in the S2 group than in the SS group. Although we failed to achieve the primary outcome, it is possible that the Jeju waters improve glycemic control compared with the Seoul tap water in diabetic patients.

Full Text Available Unlike other advertising mediums such as TV commercials or online advertising, people involuntarily receive sport advertisements; they prefer to watch the game for the sporting action than the regular advertisements. However, it is important to analyse their general attitudes among various questions, mostly due to the reason it varies from demographic group to demographic group. Hence, this research was aimed at gaining relevant knowledge about the attitudes of Montenegrin consumers toward advertising through sport among the question how often consumers purchase sporting goods. The sample included 342 respondents, divided into six subsample groups: consumers who do not purchase sport goods at all, then consumers who purchase sport goods less than ones a month, next 1–3 a month, 4–6 a month, 7–9 a month, as well as consumers who purchase sport goods more than 10 times a month. The sample of variables contained the system of three general attitudes which were modelled by seven-point Likert scale. The results of the measuring were analysed by multivariate analysis (MANOVA and univariate analysis (ANOVA and Post Hoc test.Based on the statistical analyses it was found that significant differences occur at multivariate level, as well as between all three variables at a significance level of (p=.000.

The evolution of the End-Use Load and Consumer Assessment Program (ELCAP) since 1983 at Bonneville Power Administration (Bonneville) has been eventful and somewhat tortuous. The birth pangs of a data set so large and encompassing as this have been overwhelming at times. The early adolescent stage of data set development and use has now been reached and preliminary results of early analyses of the data are becoming well known. However, the full maturity of the data set and the corresponding wealth of analytic insights are not fully realized. This document is in some sense a milestone in the brief history of the program. It is a summary of the results of the first five years of the program, principally containing excerpts from a number of previous reports. It is meant to highlight significant accomplishments and analytical results, with a focus on the principal results. Many of the results have a broad application in the utility load research community in general, although the real breadth of the data set remains largely unexplored. The first section of the document introduces the data set: how the buildings were selected, how the metering equipment was installed, and how the data set has been prepared for analysis. Each of the sections that follow the introduction summarize a particular analytic result. A large majority of the analyses to date involve the residential samples, as these were installed first and had highest priority on the analytic agenda. Two exploratory analyses using commercial data are included as an introduction to the commercial analyses that are currently underway. Most of the sections reference more complete technical reports which the reader should refer to for details of the methodology and for more complete discussion of the results. Sections have been processed separately for inclusion on the data base.

Wood, Kelly S; Cronley, Maria L

2014-09-01

This study examines changes over a 10-year period in consumer reports of communication with health care providers about direct-to-consumer advertised (DTCA) medications. Two rounds of survey data were collected in 2003 and 2012 using repeated cross-sectional procedures to examine consumer willingness to discuss DTCA medications, content and tone of those conversations, and attitudes about the advertisements. In total, 472 surveys were analyzed. Generally, we found physician-patient conversations, attitudes, and behaviors regarding DTCA have changed. Consumers in 2012 reported talking significantly less about the names of the advertised drug, comparing the advertised drug with their current medication, and sharing general information than consumers in 2003. Attitudes toward the advertisements were significantly more negative in 2012 compared to 2003. Of those who specifically asked for a prescription, the proportion of patients who received the prescription was significantly lower in 2012, despite research suggesting increased rates of prescriptions. These results are interpreted in light of previous research about the lack of research examining the actual communication between physicians and patients on this topic. Limitations of the study are provided along with directions for future research about DTCA and physician-patient communication.

Improvements in crop water productivity increase water sustainability and food security—a global analysis

Brauman, Kate A; Foley, Jonathan A; Siebert, Stefan

2013-01-01

Irrigation consumes more water than any other human activity, and thus the challenges of water sustainability and food security are closely linked. To evaluate how water resources are used for food production, we examined global patterns of water productivity—food produced (kcal) per unit of water (l) consumed. We document considerable variability in crop water productivity globally, not only across different climatic zones but also within climatic zones. The least water productive systems are disproportionate freshwater consumers. On precipitation-limited croplands, we found that ∼40% of water consumption goes to production of just 20% of food calories. Because in many cases crop water productivity is well below optimal levels, in many cases farmers have substantial opportunities to improve water productivity. To demonstrate the potential impact of management interventions, we calculated that raising crop water productivity in precipitation-limited regions to the 20th percentile of productivity would increase annual production on rainfed cropland by enough to provide food for an estimated 110 million people, and water consumption on irrigated cropland would be reduced enough to meet the annual domestic water demands of nearly 1.4 billion people.

An in-home beef study evaluated consumer ratings of clod steaks (n = 1,264) as influenced by USDA quality grade (Top Choice, Low Choice, High Select, and Low Select), city (Chicago and Philadelphia), consumer segment (Beef Loyals, who are heavy consumers of beef; Budget Rotators, who are cost-driven and split meat consumption between beef and chicken; and Variety Rotators, who have higher incomes and education and split their meat consumption among beef, poultry, and other foods), degree of doneness, and cooking method. Consumers evaluated each steak for Overall Like, Tenderness, Juiciness, Flavor Like, and Flavor Amount using 10-point scales. Grilling was the predominant cooking method used, and steaks were cooked to medium-well and greater degrees of doneness. Interactions existed involving the consumer-controlled factors of degree of doneness and(or) cooking method for all consumer-evaluated traits for the clod steak (P affect any consumer evaluation traits or Warner-Bratzler shear force values (P > 0.05). One significant main effect, segment (P = 0.006), and one significant interaction, cooking method x city (P = 0.0407), existed for Overall Like ratings. Consumers in the Beef Loyals segment rated clod steaks higher in Overall Like than the other segments. Consumers in Chicago tended to give more uniform Overall Like ratings to clod steaks cooked by various methods; however, consumers in Philadelphia gave among the highest ratings to clod steaks that were fried and among the lowest to those that were grilled. Additionally, although clod steaks that were fried were given generally high ratings by consumers in Philadelphia, consumers in Chicago rated clod steaks cooked in this manner significantly lower than those in Philadelphia. Conversely, consumers in Chicago rated clod steaks that were grilled significantly higher than consumers in Philadelphia. Correlation and stepwise regression analyses indicated that Flavor Like was driving customer satisfaction of the

Thallium (Tl) is an element of high toxicity and significant accumulation in human body. There is an urgent need for the development of appropriate strategies for trace Tl removal in drinking water treatment plants. In this study, the efficiency and mechanism of trace Tl (0.5 μg/L) removal by conventional coagulation enhanced by nanosized manganese dioxide (nMnO 2 ) were explored in simulated water and two representative surface waters (a river water and a reservoir water obtained from Northeast China). Experimental results showed that nMnO 2 significantly improve Tl(I) removal from selected waters. The removal efficiency was dramatically higher in the simulated water, demonstrating by less than 0.1 μg/L Tl residual. The enhancement of trace Tl removal in the surface waters decreased to a certain extent. Both adjusting water pH to alkaline condition and preoxidation of Tl(I) to Tl(III) benefit trace Tl removal from surface waters. Data also indicated that competitive cation of Ca 2+ decreased the efficiency of trace Tl removal, resulting from the reduction of Tl adsorption on nMnO 2 . Humic acid could largely low Tl removal efficiency during nMnO 2 enhanced coagulation processes. Trace elemental Tl firstly adsorbed on nMnO 2 and then removed accompanying with nMnO 2 settling. The information obtained in the present study may provide a potential strategy for drinking water treatment plants threatened by trace Tl. Copyright © 2016 Elsevier Ltd. All rights reserved.

Based on a survey with members of an online consumer panel (N= 699), this study revealed that: (a) a substantial percentage of consumers held misperceptions about the chemical imbalance theory of depression; (b) personal and interpersonal experiences with depression positively related to such misperceptions; (c) overall, exposure to direct-to-consumer (DTC) antidepressant advertising did not significantly relate to misperceptions; and (d) DTC exposure magnified misperceptions when consumers were highly trustful of DTC advertising, whereas exposure diluted misperceptions when consumers were highly skeptical. Theoretical and practical implications of the research are discussed, especially in light of the social responsibility of DTC advertising.

Significance of losses in water distribution systems in India.

Raman, V

1983-01-01

Effective management of water supply systems consists in supplying adequate quantities of clean water to the population. Detailed pilot studies of water distribution systems were carried out in 9 cities in India during 1971-81 to establish the feasibility of a programme of assessment, detection, and control of water losses from supply systems. A cost-benefit analysis was carried out. Water losses from mains and service pipes in the areas studied amounted to 20-35% of the total flow in the system. At a conservative estimate, the national loss of processed water through leaks in the water distribution systems amounts to 10(12) litres per year, which is equivalent to 500 million rupees.It is possible to bring down the water losses in the pipe mains to 3-5% of the total flow, and the cost incurred on the control programme can be recovered in 6-18 months. Appropriate conservation measures will help in achieving the goals of the International Water Supply and Sanitation Decade to provide clean water for all.

Facilitating consumer participation: an approach to finding the 'right' consumer.

Science.gov (United States)

Happell, Brenda

2010-01-01

Contemporary health care increasingly dictates that consumers of services should become active participants in the health care system. This has placed responsibility on administrators, managers and clinicians to include consumers in key strategic and decision making initiatives. However, this direction has not been accompanied by clear policies or guidelines. Consequently confusion about selecting consumers able to provide valuable input is identified as a barrier to active consumer involvement. The purpose of this paper is to address some concerns raised in the quest to find the "right" consumer, including: finding a consumer without an axe to grind; ensuring the consumer is representative of broader views; health professionals as consumer representatives. While these concerns are common they have not yet been extensively debated and discussed in the broader Literature. Strategies necessary to support consumers in participatory roles are also considered and the controversial subject of financial remuneration for consumers is also explored.

Balancing the Energy-Water Nexus

Energy Technology Data Exchange (ETDEWEB)

Dell, Jan

2010-09-15

Optimizing the complex tradeoffs in the Energy-Water Nexus requires quantification of energy use, carbon emitted and water consumed. Water is consumed in energy production and is often a constraint to operations. More global attention and investment has been made on reducing carbon emissions than on water management. Review of public reporting by the largest 107 global power producers and 50 companies in the oil/gas industry shows broad accounting on carbon emissions but only partial reporting on water consumption metrics. If the Energy-Water Nexus is to be balanced, then water must also be measured to be optimally managed with carbon emissions.

Correlating consumer perception and consumer acceptability of traditional Doenjang in Korea.

Kim, Mina K; Lee, Kwang-Geun

2014-11-01

Doenjang is a traditional Korean food and is widely used for many Korean foods. Consumer perception and consumer acceptability on the typical sensory characteristics of traditional Doenjang remain unknown. The objective of the current study was to determine the consumer perception on traditional Doenjang characteristics and how preexisting consumer perception influenced the consumer liking for traditionally and commercially manufactured Doenjang. A consumer survey was conducted by presenting 26 sensory descriptions to consumers (n = 82) for check-all-that-apply measurement. Then, a consumer acceptance test was conducted over 2 d on 2 Doenjang samples representing commercially produced Doenjang and traditionally produced Doenjang: Day 1 consumers evaluated without any information (n = 182), and day 2 consumers evaluated samples informed that both samples were made by the "traditional" method (n = 109). Two-way ANOVA and multivariate analyses were conducted. Consumers' preexisting perceptions on the typical sensory characteristics of traditionally made Doenjang were similar in that they associate "gu-soo flavor," "dark color," "flavorful," and "well-fermented flavor" regardless of consumer demographics and Doenjang user status. However, these consumer perceptions on sensory attributes of traditional Doenjang did not agree with desirable sensory attributes for consumer liking, in that consumers preferred the commercially made Doenjang regardless of the evaluation condition and consumer user status. Findings from the current study therefore suggested a discrepancy between the preexisting current consumer perception and actual consumer acceptability of traditional Doenjang products. © 2014 Institute of Food Technologists®

Joint management of water and electricity in State Water Project

Understanding the relationship between California's water and electrical power is important for improving the management and planning of these two vital resources to the state's economy development and people's well-being. It is often unclear for consumers, managers and decision-makers that water and electricity in California are inextricably connected. In the past, insufficient considerations of electricity production, consumption and cost in the State Water Project (SWP) - the world's largest publicly built and operated water and power development and conveyance system-has led to significant water rate and electricity rate increase. An innovative concept of this proposed study is developing new technology capable of managing and planning water and power jointly in SWP to promote its operation efficiency, sustainability and resilience to potential water shortage caused by climate change and population increase. To achieve this goal, a nonlinear, two-fold network model describing water delivery in company with power consumption and generation will be constructed, and a multi-objective optimization scheme is to be used to resolve this complex nonlinear network problem.

MEASUREMENT OF CONSUMER ETHNOCENTRISM OF SLOVAK CONSUMERS

Directory of Open Access Journals (Sweden)

Janka Taborecka-Petrovicova

2014-10-01

Full Text Available The conceptualization of consumer ethnocentrism is inferred from the general concept of ethnocentrism which assumes that ethnocentrism starts with the culture into which an individual is born. Over time, the individual will accept the values and behaviour of this particular culture as a norm. However, when the individual becomes aware of other cultures with different values and behaviours, there develops the need of belonging and identification with own culture rather than that of others. When analysing the consumer ethnocentrism, it is also essential to examine whether consumer ethnocentrism operates uniformly across all consumers or there exist some specific factors moderating their ethnocentric tendencies. A lot of studies researching these issues can be found in various cultural contexts, however in Slovakia we found certain gap since there is just a few of them. The aim of the paper is to investigate the level of consumer ethnocentricity of Slovak consumers in general and with the respect to chosen variables – age and gender. The results can serve as an information base for decision-making process of marketing managers focusing especially on local production of domestic products.

Consumer-driven nutrient dynamics in freshwater ecosystems: from individuals to ecosystems.

Atkinson, Carla L; Capps, Krista A; Rugenski, Amanda T; Vanni, Michael J

The role of animals in modulating nutrient cycling [hereafter, consumer-driven nutrient dynamics (CND)] has been accepted as an important influence on both community structure and ecosystem function in aquatic systems. Yet there is great variability in the influence of CND across species and ecosystems, and the causes of this variation are not well understood. Here, we review and synthesize the mechanisms behind CND in fresh waters. We reviewed 131 articles on CND published between 1973 and 1 June 2015. The rate of new publications in CND has increased from 1.4 papers per year during 1973-2002 to 7.3 per year during 2003-2015. The majority of investigations are in North America with many concentrating on fish. More recent studies have focused on animal-mediated nutrient excretion rates relative to nutrient demand and indirect impacts (e.g. decomposition). We identified several mechanisms that influence CND across levels of biological organization. Factors affecting the stoichiometric plasticity of consumers, including body size, feeding history and ontogeny, play an important role in determining the impact of individual consumers on nutrient dynamics and underlie the stoichiometry of CND across time and space. The abiotic characteristics of an ecosystem affect the net impact of consumers on ecosystem processes by influencing consumer metabolic processes (e.g. consumption and excretion/egestion rates), non-CND supply of nutrients and ecosystem nutrient demand. Furthermore, the transformation and transport of elements by populations and communities of consumers also influences the flow of energy and nutrients across ecosystem boundaries. This review highlights that shifts in community composition or biomass of consumers and eco-evolutionary underpinnings can have strong effects on the functional role of consumers in ecosystem processes, yet these are relatively unexplored aspects of CND. Future research should evaluate the value of using species traits and abiotic

Nudging strategies have recently attracted attention from scholars and policy makers for their potential in influencing people's behaviors on large scales. But is the fact that nudges do not forbid any choice-options or significantly alter people's economic incentives sufficient to conclude that nudges should be implemented? While this is discussed amongst scholars from various disciplines the voices of consumers, the target-group of nudges, remain unheard. Since understanding their knowledge about nudging and their opinions on being nudged are crucial for the evaluation of the moral appropriateness of nudging, the current study examines consumers' knowledge of and attitudes toward nudging in general and the realm of health behavior. In this qualitative investigation in-depth semi-structured interviews with UK consumers were conducted to examine consumers' attitudes to four domains of inquiry around which the scholarly discussions about nudging have revolved: consumers' approval of nudging, consumers' views on the origin of nudges, consumers' perceived effectiveness of nudging, and consumers' concerns about manipulative aspects of nudging. Interviews revealed that consumers are largely unfamiliar with the concept of nudging altogether. Once defined and explained to them most consumers approve of the concept, especially in the realm of health behavior, given particular conditions: 1. Nudges should be designed for benefiting individuals and society; 2. consumers comprehend the decision-making context and the reasoning behind the promotion of the targeted behavior. Interviews revealed very limited concerns with manipulative aspects of nudges. These findings call for better information-management to ensure consumers knowledge of nudges and awareness of their current implementation. Under that condition the findings encourage the implementation of nudges benefitting individuals and society in domains that consumers comprehend, such as health behaviors. Further research

To assess the experience of enrollees in a consumer-driven health plan (CDHP). Survey of University of Minnesota employees regarding their 2002 health benefits. Comparison of regression-adjusted mean values for CDHP and other plan enrollees: customer service, plan paperwork, overall satisfaction, and plan switching. For CDHP enrollees only, use of plan features, willingness to recommend the plan to others, and reports of particularly negative or positive experiences. There were significant differences in experiences of CDHP enrollees versus enrollees in other plans with customer service and paperwork, but similar levels of satisfaction (on a 10-point scale) with health plans. Eight percent of CDHP enrollees left their plan after one year, compared to 5 percent of enrollees leaving other plans. A minority of CDHP enrollees used online plan features, but enrollees generally were satisfied with the amount and quality of the information provided by the CDHP. Almost half reported a particularly positive experience, compared to a quarter reporting a particularly negative experience. Thirty percent said they would recommend the plan to others, while an additional 57 percent said they would recommend it depending on the situation. Much more work is needed to determine how consumer experience varies with the number and type of plan options available, the design of the CDHP, and the length of time in the CDHP. Research also is needed on the factors that affect consumer decisions to leave CDHPs.

Roles and significance of water conducting features for transport models in performance assessment

Carrera, J.; Sanchez-Vila, X.; Medina, A.

1999-01-01

The term water conducting features (WCF) refers to zones of high hydraulic conductivity. In the context of waste disposal, it is further implied that they are narrow so that chances of sampling them are low. Yet, they may carry significant amounts of water. Moreover, their relatively small volumetric water content causes solutes to travel fast through them. Water-conducting features are a rather common feature of natural media. The fact that they have become a source of concern in recent years, reflects more the increased level of testing and monitoring than any intrinsic property of low permeability media. Accurate simulations of solute transport require a realistic accounting for water conducting features. Methods are presented to do so and examples are shown to illustrate these methods. Since detailed accounting of WCF's will not be possible in actual performance assessments, efforts should be directed towards typification, so as to identify the essential effects of WCF's on solute transport through different types of rocks. Field evidence suggests that, although individual WCF's may be difficult to characterize, their effects are quite predictable. (author)

Water and energy resources are fundamental to life on Earth and essential for the production of consumer goods and services in the economy. Energy and water resources are heavily interdependent—energy production consumes water, while water treatment and distribution consume energy. One example of this so-called energy-water nexus is the consumption of water associated with the production of transportation fuels. The Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation (GREET) model is an analytical tool that can be used to compare the environmental impacts of different transportation fuels on a consistent basis. In this presentation, the expansion of GREET to perform life cycle water accounting or the "virtual flow" of water into transportation and other energy sectors and the associated implications will be discussed. The results indicate that increased usage of alternative fuels may increase freshwater resource consumption. The increased water consumption must be weighed against the benefits of decreased greenhouse gas and fossil energy consumption. Our analysis highlights the importance of regionality, co-product allocation, and consistent system boundaries when comparing the water intensity of alternative transportation fuel production pathways such as ethanol, biodiesel, compressed natural gas, hydrogen, and electricity with conventional petroleum-based fuels such as diesel and gasoline.

Full Text Available The ozone-depleting and greenhouse gas, nitrous oxide (N2O, is mainly consumed by the microbially mediated anaerobic process, denitrification. N2O consumption is the last step in canonical denitrification, and is also the least O2 tolerant step. Community composition of total and active N2O consuming bacteria was analyzed based on total (DNA and transcriptionally active (RNA nitrous oxide reductase (nosZ genes using a functional gene microarray. The total and active nosZ communities were dominated by a limited number of nosZ archetypes, affiliated with bacteria from marine, soil and marsh environments. In addition to nosZ genes related to those of known marine denitrifiers, atypical nosZ genes, related to those of soil bacteria that do not possess a complete denitrification pathway, were also detected, especially in surface waters. The community composition of the total nosZ assemblage was significantly different from the active assemblage. The community composition of the total nosZ assemblage was significantly different between coastal and off-shore stations. The low oxygen assemblages from both stations were similar to each other, while the higher oxygen assemblages were more variable. Community composition of the active nosZ assemblage was also significantly different between stations, and varied with N2O concentration but not O2. Notably, nosZ assemblages were not only present but also active in oxygenated seawater: the abundance of total and active nosZ bacteria from oxygenated surface water (indicated by nosZ gene copy number was similar to or even larger than in anoxic waters, implying the potential for N2O consumption even in the oxygenated surface water.

Methods: One thousand and seven adult consumers (aged 20–50 years were randomly selected from all over South Korea between November 1 and 9, 2010. We surveyed the origin and degree of their concern and their need for information and education regarding nanomaterials. Results: Analysis of the survey results showed no significant differences in responses by sex, age, and level of education, but significant differences were found in responses based on average monthly household income. Our research showed that consumers have vague expectations for and positive image of nanotechnology and nanoproducts but do not clearly understand what they are. In addition, we found that preparing and disseminating information to consumers is required in order to provide correct information about nanotechnology to the public. Conclusion: A communication system should be established among the multiple stakeholders involved

Full Text Available Fossil energy and water resources are both important for economic and social development in China, and they are tightly interlinked. Fossil energy production consumes large amounts of water, and it is essential to investigate the water footprint of fossil energy production (WFEP in China. In addition, fossil energy is supplied to consumers in China by both domestic and foreign producers, and understanding the water footprint of fossil energy supply (WFES is also highly significant for water and energy development programs in the long-term. The objectives of this paper were to provide an estimation of the blue component of WFEP and WFES in China for the period from 2001 to 2014, and to evaluate the impact on water resources from energy production, the contribution of internal and external WFES, and water-energy related issues of the international energy trade by applying water footprint analysis based on the bottom-up approach. The results indicate that generally, the WFEP and WFES in China both maintained steady growth before 2013, with the WFEP increasing from approximately 3900 million m3/year to 10,400 million m3/year, while the WFES grew from 3900 million m3/year to 11,600 million m3/year. The fossil energy production caps of the 13th Five Year Plan can bring the water consumed for fossil energy production back to a sustainable level. Over the long-term, China’s energy trade plan should also consider the water and energy resources of the countries from which fossil energy is imported.

Full Text Available Water quality monitoring is prone to encounter error on its recording or measuring process. The monitoring on river water quality not only aims to recognize the water quality dynamic, but also to evaluate the data to create river management policy and water pollution in order to maintain the continuity of human health or sanitation requirement, and biodiversity preservation. Evaluation on water quality monitoring needs to be started by identifying the important water quality parameter. This research objected to identify the significant parameters by using two transformation or standardization methods on water quality data, which are the river Water Quality Index, WQI (Indeks Kualitas Air, Sungai, IKAs transformation or standardization method and transformation or standardization method with mean 0 and variance 1; so that the variability of water quality parameters could be aggregated with one another. Both of the methods were applied on the water quality monitoring data which its validity and reliability have been tested. The PCA, Principal Component Analysis (Analisa Komponen Utama, AKU, with the help of Scilab software, has been used to process the secondary data on water quality parameters of Gadjah Wong river in 2004-2013, with its validity and reliability has been tested. The Scilab result was cross examined with the result from the Excel-based Biplot Add In software. The research result showed that only 18 from total 35 water quality parameters that have passable data quality. The two transformation or standardization data methods gave different significant parameter type and amount result. On the transformation or standardization mean 0 variances 1, there were water quality significant parameter dynamic to mean concentration of each water quality parameters, which are TDS, SO4, EC, TSS, NO3N, COD, BOD5, Grease Oil and NH3N. On the river WQI transformation or standardization, the water quality significant parameter showed the level of

Water is the main composition of the geo-fiuid. With the changes of temperature and pressure, its phases and physicochemical properties will vary and the critical singularity occur at the critical point of second-order phase transition. These changes of water will enormously affect the hydrothermal mineralizations. This paper has introduced the types and characteristics of water phase transitions, studied the phase transitions of water in the lithosphere and showed the critical singularity of water with the example of the isobaric heat capacity. The conclusions are as follow: (1) the critical singularities of water are the most obvious as the temperature and pressure near to the critical constants of water; (2) Because the temperature changes with the pressure according to the thermal curve in the lithosphere, it is difficult to find a place where the temperature and pressure can be at the critical constants at same time except the coupling effect of the hydrothermal processes, intermediate-acidic magmatism and faulting; (3) To the hydrothermal mineralization, the significances of water's critical singularities at least include the sharp variation of solubility and instantaneous high pressure to conduct the deposit of ore-forming materials and fault formation.

Full Text Available The natural surface water, especially available through rivers, is the main source of healthy water for the living beings throughout the world from ancient days as it consists of all essential minerals. With the advent of industrialization, gradually even the most prominent rivers have been polluted in all parts of the world. Although there are lots of technologies, nanofiltration (NF has been chosen to transform river water into healthy water due to its unique advantages of retaining optimum TDS (with essential minerals required for human body, consuming of lower energy, and no usage of any chemicals. The prominent parameters of surface water and macro/microminerals of treated water have been analyzed. It is shown that NF is better in producing healthy water with high flux by consuming low energy.

Health care consumer reports: an evaluation of consumer perspectives.

Science.gov (United States)

Longo, Daniel R; Everet, Kevin D

2003-01-01

There has been a proliferation of health care consumer reports, also known as "consumer guides," "report cards," and "performance reports," which are designed to assist consumers in making more informed health care decisions. While there is evidence that providers use such reports to identify and make changes in practice, thus improving the quality of care, there is little empirical evidence on how consumer guides/report cards are used by consumers. This study fills that gap by surveying 925 patients as they wait for ambulatory care in several clinics in a midwestern city. Findings indicate that consumers are selective in their use of these reports and quickly identify those sections of the report of most interest to them. Report developers should take precautions to ensure such reports are viewed as credible sources of health care information.

Full Text Available This study was proposed to explore the determinants of consumer preferences in Addis Ababa restaurants. Using consumer behavior literatures and theories it was hypothesized that disposable income, price, quality, hygiene practices, friendliness of restaurant staff, safety of food and range or menu variety are important determinants of consumer choice for restaurants. Primary data were generated from 265 customers of 55 restaurants randomly selected with the use of questionnaire of which 258 of the questionnaire ended usable. The non parametric hypothesis testing statistical tool, chi –square tests, and measures of variation were used for statistical analysis purposes. The anticipation of the researcher was that the hypothesis testing results would be significant in parallel with the hypothesized facts. The findings of the research suggest that income has insignificant impact up on quality price trade of among consumers of different income categories. Other hypothesis associated with price, quality, friendliness of restaurant staff, quick table service and range or menu varieties are found to be statistically significant. Over all, the research results suggest that restaurateurs should design marketing strategy that integrates the attributes used in this study to satisfy the needs and wants of their customers and differentiation of their products and services on the basis of the variables scored as they are significant considerations by consumers.

Evaluating Outdoor Water Use Demand under Changing Climatic and Demographic Conditions: An Agent-based Modeling Approach

Kanta, L.; Berglund, E. Z.; Soh, M. H.

Outdoor water-use for landscape and irrigation constitutes a significant end-use in total residential water demand. In periods of water shortages, utilities may reduce garden demands by implementing irrigation system audits, rebate programs, local ordinances, and voluntary or mandatory water-use restrictions. Because utilities do not typically record outdoor and indoor water-uses separately, the effects of policies for reducing garden demands cannot be readily calculated. The volume of water required to meet garden demands depends on the housing density, lawn size, type of vegetation, climatic conditions, efficiency of garden irrigation systems, and consumer water-use behaviors. Many existing outdoor demand estimation methods are deterministic and do not include consumer responses to conservation campaigns. In addition, mandatory restrictions may have a substantial impact on reducing outdoor demands, but the effectiveness of mandatory restrictions depends on the timing and the frequency of restrictions, in addition to the distribution of housing density and consumer types within a community. This research investigates a garden end-use model by coupling an agent-based modeling approach and a mechanistic-stochastic water demand model to create a methodology for estimating garden demand and evaluating demand reduction policies. The garden demand model is developed for two water utilities, using a diverse data sets, including residential customer billing records, outdoor conservation programs, frequency and type of mandatory water-use restrictions, lot size distribution, population growth, and climatic data. A set of garden irrigation parameter values, which are based on the efficiency of irrigation systems and irrigation habits of consumers, are determined for a set of conservation ordinances and restrictions. The model parameters are then validated using customer water usage data from the participating water utilities. A sensitivity analysis is conducted for garden

2010-07-01

Mining is an energy-intensive industry, and most processing mills use wet processes to separate minerals from ore. This paper discussed water reduction, reuse and recycling options for a mining and mill operation network. A mine water network design was then proposed in order to identify and reduce water and system energy requirements. This included (1) a description of site water balance, (2) a description of potential water sources, (3) a description of water consumers, (4) the construction of energy requirement matrices, and (5) the use of linear programming to reduce energy requirements. The design was used to determine a site water balance as well as to specify major water consumers during mining and mill processes. Potential water supply combinations, water metering technologies, and recycling options were evaluated in order to identify the most efficient energy and water use combinations. The method was used to highlight potential energy savings from the integration of heating and cooling systems with plant water systems. 43 refs., 4 tabs., 3 figs.

A probabilistic assessment was made of the effects on public dose of water hammer events in LWRs. The analysis utilized actual historical water hammer data to determine if the water hammer events contributed either to system failure rates or initiating event frequencies. Representative PRAs were used to see if changes in initiating events and/or system failures caused by water hammer resulted in new values for the dominant sequences in the PRAs. New core melt frequencies were determined and carried out to the subsequent increase in public dose. It is concluded that water hammer is not a significant problem with respect to risk to the public for either BWRs or PWRs. (orig./HP)

Full Text Available This paper tests the applicability of the CSI instrument to measuring consumer decision-making styles in the Croatian environment. The analysis assesses the validity and the reliability of CSI scales and examines gender differences in consumer-decision making styles. Research results point to the existence of eight consumer characteristics and thus validate the applicability of CSI instrument in the Croatian environment. Our findings further indicate that there were gender differences on five factors of consumer-decision making styles (perfectionist, novelty-fashion consciousness, recreational-hedonistic consumer, impulsiveness, habitual shopping behavioral. No significant differences in consumer decision styles between men and women were found with regard to three factors (brand consciousness, price consciousness and confused by overabundant choice. The CSI measurement system may help practitioners to gain a better understanding of how to position their products and services more effectively.

Park, Jin Seong; Ju, Ilwoo; Kim, Kenneth Eunhan

2014-01-01

Although exposure to direct-to-consumer prescription drug advertising (DTCA) is reported to influence the public's beliefs about diseases, no research has investigated how DTCA may affect the extent of consumers' optimistic bias about the future risk of diseases. Based on a survey with members of an online consumer panel (n = 699), the current study revealed that: (a) Consumers exhibited a tendency to believe they were at less risk of developing clinical depression in the future than their peers, demonstrating an optimistic bias. (b) Exposure to antidepressant DTCA acted to reduce the extent of such bias, especially when consumers were less skeptical of prescription drug advertising. When consumers were highly skeptical, DTCA exposure did not significantly relate to the extent of optimistic bias. (c) Once formed, the extent of optimistic bias negatively related to consumers' intention to seek information about depression. Implications of the research for the theory and practice of DTCA were discussed.

Full Text Available Sparkling wine represents a small but significant proportion of the Australian wine industry’s total production. Yet, Australia remains a significant importer of French Champagne. This study investigated consumer preferences for Australian sparkling wine vs. French Champagne and any compositional and/or sensorial bases for these preferences. A range of French and Australian sparkling wines were analyzed by MIR spectroscopy to determine if sparkling wines could be differentiated according to country of origin. A subset of wines, comprising two French Champagnes, a French sparkling wine and three Australian sparkling wines, were selected for (i descriptive analysis to characterize their sensory profiles and (ii acceptance tests to determine consumer liking (n = 95 Australian wine consumers. Significant differences were observed between liking scores; on average, the $70 French Champagne was liked least and the $12 Australian sparkling wine liked most, but segmentation (based on individual liking scores identified clusters comprising consumers with distinct wine preferences. Interestingly, when consumers were shown wine bottle labels, they considered French wines to be more expensive than Australian wines, demonstrating a clear country of origin influence.

Full Text Available The paper concerns two interacting consumer-resource pairs based on chemostat-like equations under the assumption that the dynamics of the resource is considerably slower than that of the consumer. The presence of two different time scales enables to carry out a fairly complete analysis of the problem. This is done by treating consumers and resources in the coupled system as fast-scale and slow-scale variables, respectively, and subsequently considering developments in phase planes of these variables, fast and slow, as if they are independent. When uncoupled, each pair has unique asymptotically stable steady state and no self-sustained oscillatory behavior (although damped oscillations about the equilibrium are admitted. When the consumer-resource pairs are weakly coupled through direct reciprocal inhibition of consumers, the whole system exhibits self-sustained relaxation oscillations with a period that can be significantly longer than intrinsic relaxation time of either pair. It is shown that the model equations adequately describe locally linked consumer-resource systems of quite different nature: living populations under interspecific interference competition and lasers coupled via their cavity losses.

Studies have shown that the average drinking water consumption ranges between 0.075 and 3 L/day for adults with both national and regional differences. For exposure assessment of drinking water hazards, country-specific drinking water consumption data including sources of the consumed water may therefore be warranted. To estimate the amount and source of drinking water consumed among adults in Sweden, we collected self-reported estimates using both traditional methods (telephone interviews, web questionnaire) and a novel method (Short Message Service, SMS questionnaires) in a population from an average sized Swedish municipality. Monthly SMS questionnaires were sent out during one year to obtain longitudinal information as well. SMS showed to be a promising tool for collecting self-reported consumption, as most citizens could participate and the method showed high response rate. Data collected via the SMS questionnaire shows an average consumption of cold tap water of 4.9 glasses/24 h (one glass=200 ml), while the average estimates of cold tap water collected by the traditional methods range from 4.5 to 7.0 glasses/24 h. For statistical distributions, the mean daily consumption of cold tap water for the population was best fitted to a gamma distribution. About 70% of the cold tap water is consumed at home. Based on the results from the SMS study, we suggest using 1 l/day for the average adult population and 2.5 l/day for high consumers for risk assessment of cold tap water consumption. As 46% of the tap water consumed is heated, we suggest using 1.85 l/day for total tap water consumption.

Effect of Consuming Oat Bran Mixed in Water before a Meal on Glycemic Responses in Healthy Humans—A Pilot Study

Directory of Open Access Journals (Sweden)

Robert E. Steinert

2016-08-01

Full Text Available Background: Viscous dietary fibers including oat β-glucan are one of the most effective classes of functional food ingredients for reducing postprandial blood glucose. The mechanism of action is thought to be via an increase in viscosity of the stomach contents that delays gastric emptying and reduces mixing of food with digestive enzymes, which, in turn, retards glucose absorption. Previous studies suggest that taking viscous fibers separate from a meal may not be effective in reducing postprandial glycemia. Methods: We aimed to re-assess the effect of consuming a preload of a commercially available oat-bran (4.5, 13.6 or 27.3 g containing 22% of high molecular weight oat β-glucan (O22 (OatWell®22 mixed in water before a test-meal of white bread on glycemic responses in 10 healthy humans. Results: We found a significant effect of dose on blood glucose area under the curve (AUC (p = 0.006 with AUC after 27.3 g of O22 being significantly lower than white bread only. Linear regression analysis showed that each gram of oat β-glucan reduced glucose AUC by 4.35% ± 1.20% (r = 0.507, p = 0.0008, n = 40 and peak rise by 6.57% ± 1.49% (r = 0.582, p < 0.0001. Conclusion: These data suggest the use of oat bran as nutritional preload strategy in the management of postprandial glycemia.

Dengue transmission in urban areas is strongly influenced by a range of biological and environmental factors, yet the key drivers still need further exploration. To better understand mechanisms of environment–mosquito–urban dengue transmission, we propose an empirical model parameterized and cross-validated from a unique dataset including viral gene sequences, vector dynamics and human dengue cases in Guangzhou, China, together with a 36-year urban environmental change maps investigated by spatiotemporal satellite image fusion. The dengue epidemics in Guangzhou are highly episodic and were not associated with annual rainfall over time. Our results indicate that urban environmental changes, especially variations in surface area covered by water in urban areas, can substantially alter the virus population and dengue transmission. The recent severe dengue outbreaks in Guangzhou may be due to the surge in an artificial lake construction, which could increase infection force between vector (mainly Aedes albopictus) and host when urban water area significantly increased. Impacts of urban environmental change on dengue dynamics may not have been thoroughly investigated in the past studies and more work needs to be done to better understand the consequences of urbanization processes in our changing world. - Highlights: • Urban dengue outbreak is associated with water area in Guangzhou, 1978–2014. • Surface water area can alter population size of dengue virus in urban area. • Urban dengue outbreak is not associated with annual rainfall in Guangzhou. • Spatiotemporal satellite image fusion can investigate urban environmental change. • Urban environmental change could induce virus, vector, and dengue epidemic change.

Water : a commodity or resource?

International Nuclear Information System (INIS)

Pomeroy, G.

2003-01-01

Over the past several years, natural gas demand has increased significantly, as it is seen as an environmentally friendly, convenient and cost effective fuel. As a result, Alberta should experience the development of a sustainable resource in the form of natural gas from coal, provided adequate management of associated water is in place. The environmental impact and volume of water produced with natural gas from coal can be significant. Water is scarce and demand is growing. Gas producers are faced with the challenge of high water production and disposal costs, and often choose the deep disposal option as the most economical solution. However, environmentalists and agriculture groups who view water as a valuable resource, warrant the costs associated with the treatment of produced water. The author proposed a conceptual solution to this dilemma concerning produced water. It was suggested that producers of water should be connected with consumers, while allowing free market supply and demand dynamics to price out the inefficient use of the resource. The author also discussed the related regulatory, environmental, technological, economic, and commercial issues. It was concluded that water is both a resource and a commodity. Alberta should implement measures to promote water conservation, pollute less, and manage supply and demand. figs

Possible significance of cubic water-ice, H2O-Ic, in the atmospheric water cycle of Mars

Science.gov (United States)

Gooding, James L.

1988-01-01

The possible formation and potential significance of the cubic ice polymorph on Mars is discussed. When water-ice crystallizes on Earth, the ambient conditions of temperature and pressure result in the formation of the hexagonal ice polymorph; however, on Mars, the much lower termperature and pressures may permit the crystallization of the cubic polymorph. Cubic ice has two properties of possible importance on Mars: it is an excellant nucleator of other volatiles (such as CO2), and it undergoes an exothermic transition to hexagonal ice at temperatures above 170 K. These properties may have significant implications for both martian cloud formation and the development of the seasonal polar caps.

Water reuse in South America: A Chilean study

The driest desert in the western hemisphere is the source of the largest and most lucrative copper mining and processing business in South America. The newest, most explosive capitalist economy in South America is fueled by an industry whose ancient water supply is on the verge of collapse. Farther south, a textbook example of 1950's industrial pollution continues to be dumped in the Bio Bio River, the water supply of the country's third largest city. In the temperate Central Valley, public health advisories regularly warn consumers against consuming vegetables irrigated with river water containing raw sewage. In the warm summer months, hepatitis and cholera epidemics are frequent and deadly. In the last 5 years, these areas have initiated major sewage treatment plant and system improvements with significant reuse components. The technologies and reuse applications of reclaimed water that are now being used in Chile are being monitored and evaluated by Peru, Argentina, and Brazil. Major efforts at environmental cleanups are now being combined with new strategies to sue reclaimed water to meet the needs of South American in the 21st century.

Can consumers save energy? Results from surveys of consumer adoption and use of low and zero carbon technologies

2007-07-01

This paper presents results from a UK Open Univ. research project which surveyed consumers' reasons for adoption - and non-adoption - of domestic energy efficiency measures and renewable energy systems - collectively called low and zero carbon (LZC) technologies. Data was gathered during 2006 via an on-line questionnaire with nearly 400 responses, mainly from 'green' consumers, supplemented by 83 in-depth telephone interviews. These consumer surveys also identified problems and benefits experienced by adopters of these LZC technologies.The paper outlines some results of these surveys, for four established energy efficiency measures - loft insulation, condensing boilers, heating controls, and energy-efficient lighting - and for four renewable energy technologies - solar water heating, solar photovoltaics (PV), micro-wind turbines and wood stoves. These consumers typically adopted the energy efficiency measures and renewable energy systems to save energy, money and/or the environment, which many considered they achieved despite some rebound effects. The reasons for considering but rejecting these LZC technologies include the familiar cost barriers, but there were also other obstacles that varied according to the product or system concerned. An important finding is that most adopters of renewable energy systems have previously adopted two or more energy efficiency measures. Thus one conclusion is: sell energy efficiency first, then renewables. Whilst in the UK very few people have adopted household renewable energy systems, about a third of the consumers in our on-line survey said that they seriously considered adopting a renewable energy technology, although, only about 20 % of these actually did so. There seems to be considerable interest in household renewables in the UK, especially among older, middle class green consumers, but so far only relatively few pioneer adopters (notably retired couples) have managed to overcome the barriers of cost, time

We assessed current water consumption during liquid fuel production, evaluating major steps of fuel lifecycle for five fuel pathways: bioethanol from corn, bioethanol from cellulosic feedstocks, gasoline from U.S. conventional crude obtained from onshore wells, gasoline from Saudi Arabian crude, and gasoline from Canadian oil sands. Our analysis revealed that the amount of irrigation water used to grow biofuel feedstocks varies significantly from one region to another and that water consumption for biofuel production varies with processing technology. In oil exploration and production, water consumption depends on the source and location of crude, the recovery technology, and the amount of produced water re-injected for oil recovery. Our results also indicate that crop irrigation is the most important factor determining water consumption in the production of corn ethanol. Nearly 70% of U.S. corn used for ethanol is produced in regions where 10-17 liters of water are consumed to produce one liter of ethanol. Ethanol production plants are less water intensive and there is a downward trend in water consumption. Water requirements for switchgrass ethanol production vary from 1.9 to 9.8 liters for each liter of ethanol produced. We found that water is consumed at a rate of 2.8-6.6 liters for each liter of gasoline produced for more than 90% of crude oil obtained from conventional onshore sources in the U.S. and more than half of crude oil imported from Saudi Arabia. For more than 55% of crude oil from Canadian oil sands, about 5.2 liters of water are consumed for each liter of gasoline produced. Our analysis highlighted the vital importance of water management during the feedstock production and conversion stage of the fuel lifecycle.

This paper uses consumer health informatics as a framework to explore whether and how direct-to-consumer personal genomic testing can be regarded as a form of information which assists consumers to manage their health. It presents findings from qualitative content analysis of web sites that offer testing services, and of transcripts from focus groups conducted as part a study of the Australian public's expectations of personal genomics. Content analysis showed that service offerings have some features of consumer health information but lack consistency. Focus group participants were mostly unfamiliar with the specifics of test reports and related information services. Some of their ideas about aids to knowledge were in line with the benefits described on provider web sites, but some expectations were inflated. People were ambivalent about whether these services would address consumers' health needs, interests and contexts and whether they would support consumers' health self-management decisions and outcomes. There is scope for consumer health informatics approaches to refine the usage and the utility of direct-to-consumer personal genomic testing. Further research may focus on how uptake is affected by consumers' health literacy or by services' engagement with consumers about what they really want.

Website quality indicators for consumers.

Griffiths, Kathleen M; Christensen, Helen

2005-11-15

The rating tool DISCERN was designed for use by consumers without content expertise to evaluate the quality of health information. There is some evidence that DISCERN may be a valid indicator of evidence-based website quality when applied by health professionals. However, it is not known if the tool is a valid measure of evidence-based quality when used by consumers. Since it is a lengthy instrument requiring training in its use, DISCERN may prove impractical for use by the typical consumer. It is therefore important to explore the validity of other simpler potential indicators of site quality such as Google PageRank. This study aimed to determine (1) whether the instrument DISCERN is a valid indicator of evidence-based Web content quality for consumers without specific mental health training, and (2) whether Google PageRank is an indicator of website content quality as measured by an evidence-based gold standard. This was a cross-sectional survey of depression websites using consumer and health professional raters. The main outcome measures were (1) site characteristics, (2) evidence-based quality of content as measured by evidence-based depression guidelines, (3) DISCERN scores, (4) Google PageRank, and (5) user satisfaction. There was a significant association between evidence-based quality ratings and average DISCERN ratings both for consumers (r = 0.62, P = .001) and health professionals (r = 0.80, P PageRank (r = 0.59, P = .002). However, the correlation between DISCERN scores and user satisfaction was higher than the correlation between Google PageRank and user satisfaction. DISCERN has potential as an indicator of content quality when used either by experts or by consumers. Google PageRank shows some promise as an automatic indicator of quality.

Within the research field of urban water demand management, understanding the link between environmental and water conservation attitudes and observed end use water consumption has been limited. Through a mixed method research design incorporating field-based smart metering technology and questionnaire surveys, this paper reveals the relationship between environmental and water conservation attitudes and a domestic water end use break down for 132 detached households located in Gold Coast city, Australia. Using confirmatory factor analysis, attitudinal factors were developed and refined; households were then categorised based on these factors through cluster analysis technique. Results indicated that residents with very positive environmental and water conservation attitudes consumed significantly less water in total and across the behaviourally influenced end uses of shower, clothes washer, irrigation and tap, than those with moderately positive attitudinal concern. The paper concluded with implications for urban water demand management planning, policy and practice. Crown Copyright © 2011. Published by Elsevier Ltd. All rights reserved.

2016-01-01

Growing population and water demand have increased pressure on water resources in various parts of the globe, including many transboundary river basins. While the impacts of upstream water use on downstream water availability have been analyzed in many of these international river basins, this has not been systematically done at the global scale using coherent and comparable datasets. In this study, we aim to assess the change in downstream water stress due to upstream water use in the world's transboundary river basins. Water stress was first calculated considering only local water use of each sub-basin based on country-basin mesh, then compared with the situation when upstream water use was subtracted from downstream water availability. Wefound that water stress was generally already high when considering only local water use, affecting 0.95-1.44 billion people or 33%-51% of the population in transboundary river basins. After accounting for upstream water use, stress level increased by at least 1 percentage-point for 30-65 sub-basins, affecting 0.29-1.13 billion people. Altogether 288 out of 298 middle-stream and downstream sub-basin areas experienced some change in stress level. Further, we assessed whether there is a link between increased water stress due to upstream water use and the number of conflictive and cooperative events in the transboundary river basins, as captured by two prominent databases. No direct relationship was found. This supports the argument that conflicts and cooperation events originate from a combination of different drivers, among which upstream-induced water stress may play a role. Our findings contribute to better understanding of upstream-downstream dynamics in water stress to help address water allocation problems.

Almost half of all deaths from drinking microbiologically unsafe water occur in Sub-Saharan Africa. Household water treatment and safe storage (HWTS) systems, when consistently used, can provide safer drinking water and improve health. Social marketing to increase adoption and use of HWTS depends both on the prices of and preferences for these systems. This study included 556 households from rural Tanzania across two low-income districts with low-quality water sources. Over 9 months in 2012 and 2013, we experimentally evaluated consumer preferences for six "low-cost" HWTS options, including boiling, through an ordinal ranking protocol. We estimated consumers' willingness to pay (WTP) for these options, using a modified auction. We allowed respondents to pay for the durable HWTS systems with cash, chickens or mobile money; a significant minority chose chickens as payment. Overall, our participants favored boiling, the ceramic pot filter and, where water was turbid, PuR™ (a combined flocculant-disinfectant). The revealed WTP for all products was far below retail prices, indicating that significant scale-up may need significant subsidies. Our work will inform programs and policies aimed at scaling up HWTS to improve the health of resource-constrained communities that must rely on poor-quality, and sometimes turbid, drinking water sources.

To test the hypothesis that water exchange (WE) significantly increases adenoma detection rates (ADR) compared with water immersion (WI). Low ADR was linked to increased risk for interval colorectal cancers and related deaths. Two recent randomized controlled trials of head-to-head comparison of WE, WI, and traditional air insufflation (AI) each showed that WE achieved significantly higher ADR than AI, but not WI. The data were pooled from these 2 studies to test the above hypothesis. Two trials (5 sites, 14 colonoscopists) that randomized 1875 patients 1:1:1 to AI, WI, or WE were pooled and analyzed with ADR as the primary outcome. The ADR of AI (39.5%) and WI (42.4%) were comparable, significantly lower than that of WE (49.6%) (vs. AI P=0.001; vs. WI P=0.033). WE insertion time was 3 minutes longer than that of AI (Prate (vs. AI) of the >10 mm advanced adenomas. Right colon combined advanced and sessile serrated ADR of AI (3.4%) and WI (5%) were comparable and were significantly lower than that of WE (8.5%) (vs. AI P<0.001; vs. WI P=0.039). Compared with AI and WI, the superior ADR of WE offsets the drawback of a significantly longer insertion time. For quality improvement focused on increasing adenoma detection, WE is preferred over WI. The hypothesis that WE could lower the risk of interval colorectal cancers and related deaths should be tested.

Consumer Disidentification and Its Effects on Domestic Product Purchases

2011-01-01

Consumers' local bias is an important determinant of domestic product purchase behavior. Because of its importance, authors across various disciplines have investigated this phenomenon using the consumer ethnocentrism model. However, the research reported herein demonstrates that such an approach...... provides an incomplete picture at best. This research provides an initial test of the consumer disidentification (CDI) construct. In contrast with consumer ethnocentrism, the CDI model predicts that consumers' repulsion toward their domestic country negatively affects the purchase of products made...... in their domestic country or by domestic firms. The model is tested using survey data from 1534 second-generation immigrants who were born in and live in the Netherlands. Structural equation modeling supports the model and shows that CDI has a significant impact on buying decisions beyond the effect of consumer...

Sun, Shikun; Wang, Yubao; Engel, Bernie A; Wu, Pute

2016-04-15

Scarcity of water resources is one of the major challenges in the world, particularly for the main water consumer, agriculture. Virtual water flow (VWF) promotes water redistribution geographically and provides a new solution for resolving regional water shortage and improving water use efficiency in the world. Virtual water transfer among regions will have a significant influence on the water systems in both grain export and import regions. In order to assess the impacts of VWF related grain transfer on regional water resources conditions, the study takes mainland China as study area for a comprehensive evaluation of virtual water flow on regional water resources stress. Results show that Northeast China and Huang-Huai-Hai region are the major grain production regions as well as the major virtual water export regions. National water savings related to grain VWF was about 58Gm(3), with 48Gm(3) blue water and 10Gm(3) green water. VWF changes the original water distribution and has a significant effect on water resources in both virtual water import and export regions. Grain VWF significantly increased water stress in grain export regions and alleviated water stress in grain import regions. Water stress index (WSI) of Heilongjiang and Inner Mongolia has been increased by 138% and 129% due to grain export. Stress from water shortages is generally severe in export regions, and issues with the sustainability of grain production and VWF pattern are worthy of further exploration.

The objective of this study was to determine if Chardonnay grape seed pomace (GSP), a waste stream of wine production, could be used as a functional ingredient in brewed coffee. Two consumer panels were conducted to assess the acceptance of coffee at coffee replacement (w/w) values of 0% (control), 6.25%, 12.50%, 18.75%, or 25% GSP. The 1st consumer panel (n = 80) assessed the coffee samples served "black." The 2nd panel (n = 67) assessed the coffee samples with adjustment (that is, sweeteners, milk, and cream) options available. Consumer sensory evaluation involved evaluating the 5 treatments individually for acceptance of appearance, aroma, taste/flavor, and overall acceptance using a 9-point hedonic scale. A check-all-that-apply questionnaire surveyed the sensory attributes describing aroma, appearance, and taste/flavor of the samples. Oxygen radical absorbance capacity was used to measure the effects of antioxidant levels in GSP coffee samples. Results showed that GSP could be added at 6.25% replacement without significantly affecting the overall consumer acceptance of coffee compared to the control (0% GSP). Above 6.25% GSP supplementation, the coffee beverage was described as more tan, milky, watery/dilute, and mild, and was generally less accepted by the consumers. GSP also increased the antioxidant capacity of the coffee compared to the control (0% GSP), with no significant differences among replacement values. Therefore, 6.25% GSP replacement is recommended for creating coffee beverages acceptable to consumers. Further in vivo investigation may substantiate the free-radical scavenging capacity of GSP coffee and its potential health benefits. © 2016 Institute of Food Technologists®.

2012-01-01

Full Text Available Understanding consumer behaviour in online environments is the basic factor to build an effective consumer-retailer relationship structure. The purpose of this study is to explore the influences of different values and concerns affecting search and purchase intentions of consumers and to build an integrated model, which could explain the purchase intentions of consumers in Turkey, where the majority of the population is under the age of 30. An integrated model of motivation and concern factors on the online shopping is developed to test the causal effect variables. Current study points out that hedonic value is a determinant of the consumer intention to search and purchase. Search intention has a direct impact on purchase intention. Utilitarian value does not have a significant impact on the search intention but it does have an important impact on the purchase intention. From the concern factors perspective, security has a significant impact on both search and purchase intentions, whereas there is no impact for privacy.

Environmental assessment for the Consumer Products Efficiency Standards program

Energy Technology Data Exchange (ETDEWEB)

1980-05-23

The Energy Policy and Conservation Act of 1975 as amended by the National Energy Conservation Policy Act of 1978, requires the DOE to prescribe energy efficiency standards for thirteen consumer products. The Consumer Products Efficiency Standards (CPES) program covers the following products: refrigerators and refrigerator-freezers; freezers;clothes dryers;water heaters; room air conditioners; home heating equipment (not including furnaces); kitchen ranges and ovens; central air conditioners (cooling and heat pumps); furnaces; dishwashers; television sets; clothes washers; and humidifiers and dehumidifiers. DOE is proposing two sets of standards for all thirteen consumer products: intermediate standards to become effective in 1981 for the first nine products and in 1982 for the second four products, and final standards to become effective in 1986 and 1987, respectively. The final standards are more restrictive than the intermediate standards and will provide manufacturers with the maximum time permitted under the Act to plan and develop extensive new lines of efficient consumer products. The final standards proposed by DOE require the maximum improvements in efficiency which are technologically feasible and economically justified, as required by Section 325(c) of EPCA. The thirteen consumer products account for approximately 90% of all the energy consumed in the nation's residences, or more than 20% of the nation's energy needs. Increases in the energy efficiency of these consumer products can help to narrow the gap between the nation's increasing demand for energy and decreasing supplies of domestic oil and natural gas. Improvements in the efficiency of consumer products can thus help to solve the nation's energy crisis.

How may consumer policy empower consumers for sustainable lifestyles?

DEFF Research Database (Denmark)

Thøgersen, John

At least judged by its outcome, it seems that consumers in the rich parts of the world make less of an effort at changing their lifestyle in a sustainable direction than is desired by society and than is in their own collective long-term interest. Part of the explanations is that individual......'s striving for sustainability. The relevant external conditions are an extremely diverse set of factors, perhaps their only commonality being that, unless making an organized effort, consumers can do nothing about them. Because external conditions influence all or many consumers, making them more...... facilitating for sustainable consumption can be much more effective than anything an individual consumer can do. Many of the external constraints facing consumers who want to adopt a more sustainable lifestyle are of a relative nature and their impact depends on the individual's resources. For instance...

Fruits and vegetables cultivated under controlled deficit irrigation (CDI) are called hydrosustainable (hydroSOS) products and have its own personality and are environmentally-friendly. Focus groups helped in classifying key farming, sensory, and health concepts associated with CDI-grown pistachios. Besides, focus groups also helped in stating that a logo was needed for these special foods, and that a hydroSOS index is also essential to certify that the products have been controlled by a control board. Conjoint analysis was used to check which attributes could be helpful in promoting CDI-grown pistachios among Spanish consumers in a 1st step toward the European Union (EU) market. It was clearly proved that the main silo of properties driving the attention of Spanish consumers was that related to health. The most important attributes for pistachios were "product of Spain," "rich in antioxidant," and "crunchy"; this finding was clearly related to the popularity of regional foods, the preoccupation of European consumers for their health, and the joy related to the crunchiness of toasted nuts, respectively. The use of these 3 concepts, together with the use of the hydroSOS logo, will be essential to promote hydroSOS pistachios among Spanish and EU consumers. Finally, it is important to highlight that in general Spanish consumers were willing to pay an extra amount of 1.0 euros per kg of hydroSOS pistachios. These earnings will be essential to convince Spanish farmers to implement CDI strategies and have a sustainable and environmental-friendly use of the irrigation water. © 2016 Institute of Food Technologists®.

1995-01-01

A simulated supermarket setting (SSS) test was conducted to determine whether consumers (n = 126) would purchase irradiated poultry products, and the effects of marketing strategies on consumer purchase of irradiated poultry products. Consumer preference for irradiated poultry was likewise determined using a home-use test. A slide program was the most effective educational strategy in changing consumers' purchase behavior. The number of participants who purchased irradiated boneless, skinless breasts and irradiated thighs after the educational program increased significantly from 59.5 and 61.9% to 83.3 and 85.7% for the breasts and thighs, respectively. Using a label or poster did not increase the number of participants who bought irradiated poultry products. About 84% of the participants consider it either 'somewhat necessary' or 'very necessary' to irradiate raw chicken and would like all chicken that was served in restaurants or fast food places to be irradiated. Fifty-eight percent of the participants would always buy irradiated chicken if available, and an additional 27% would buy it sometimes. About 44% of the participants were willing to pay the same price for irradiated chicken as for nonirradiated. About 42% of participants were willing to pay 5% or more than what they were currently paying for nonirradiated chicken. Seventy-three percent or more of consumers who participated in the home-use test (n = 74) gave the color, appearance, and aroma of the raw poultry products a minimum rating of 7 (= like moderately). After consumers participated in a home-use test, 84 and 88% selected irradiated thighs and breasts, respectively, over nonirradiated in a second SSS test

CONSIDERATIONS ON CONSUMER PERCEIVED RISK

Directory of Open Access Journals (Sweden)

Laura Catalina Timiras

2014-12-01

Full Text Available In this article we identified a number of factors influencing the consumers’ perceived risk. In the first part we conducted a review of the main issues that define the perceived risk by the consumer at the time of purchase, some of the lines of action of the organizations to diminish this risk perception and a number of influencing factors presented in the literature, with significant impact on the intensity with which risk is perceived by consumers. The second part of the article is based on the statistical information regarding e-commerce market, market in which the perceived risk plays an important role in the purchasing decision. Thus, based on available official statistics provided by Eurostat we have revealed the existence of certain links between electronic commerce and orientation towards risk and income levels, age and consumer educational level. The review is not intended to be exhaustive, the study taking into consideration only those links that can be identified from using official statistical data.

Microbiological and Chemical Quality of Packaged Sachet Water and Household Stored Drinking Water in Freetown, Sierra Leone.

Fisher, Michael B; Williams, Ashley R; Jalloh, Mohamed F; Saquee, George; Bain, Robert E S; Bartram, Jamie K

2015-01-01

Packaged drinking water (PW) sold in bottles and plastic bags/sachets is widely consumed in low- and middle-income countries (LMICs), and many urban users in sub-Saharan Africa (SSA) rely on packaged sachet water (PSW) as their primary source of water for consumption. However, few rigorous studies have investigated PSW quality in SSA, and none have compared PSW to stored household water for consumption (HWC). A clearer understanding of PSW quality in the context of alternative sources is needed to inform policy and regulation. As elsewhere in SSA, PSW is widely consumed in Sierra Leone, but government oversight is nearly nonexistent. This study examined the microbiological and chemical quality of a representative sample of PSW products in Freetown, Sierra Leone at packaged water manufacturing facilities (PWMFs) and at points of sale (POSs). Samples of HWC were also analyzed for comparison. The study did not find evidence of serious chemical contamination among the parameters studied. However, 19% of 45 PSW products sampled at the PWMF contained detectable Escherichia coli (EC), although only two samples exceeded 10 CFU/100 mL. Concentrations of total coliforms (TC) in PSW (but not EC) increased along the supply chain. Samples of HWC from 60 households in Freetown were significantly more likely to contain EC and TC than PSW at the point of production (p<0.01), and had significantly higher concentrations of both bacterial indicators (p<0.01). These results highlight the need for additional PSW regulation and surveillance, while demonstrating the need to prioritize the safety of HWC. At present, PSW may be the least unsafe option for many households.

Caloric beverages consumed freely at meal-time add calories to an ad libitum meal.

The objective was to compare the effects of ad libitum consumption of commonly consumed meal-time beverages on energy and fluid intakes and post-meal average subjective appetite and blood glucose in healthy adults. In a randomized controlled design, 29 males and females consumed to satiation an ad libitum pizza meal with one of five beverages in unlimited amount including water (0 kcal), 1% milk (44 kcal/100 ml), regular cola (44 kcal/100 ml), orange juice (44 kcal/100 ml) and diet cola (0 kcal). Food and fluid intakes were measured at the meal. Average subjective appetite and blood glucose were measured before and for 2h after the meal. Although energy intake from pizza was similar among all beverage treatments, the amount of fluid consumed (g) varied among the beverages with intake of orange juice higher than regular and diet cola, but not different from water or milk. Meal-time ingestion of caloric beverages, milk, orange juice and regular cola, led to higher total meal-time energy intakes compared to either water or diet cola. Post-meal blood glucose area under the curve (AUC) was lower after milk than after meals with water, orange juice and regular cola and post-meal average subjective appetite AUC was lower after milk than after meals with water. Meal intakes of nutrients including protein, calcium, phosphorus, zinc, vitamins B12, A and D were higher at the meal with milk compared to the other beverages. Thus, caloric beverages consumed ad libitum during a meal add to total meal-time energy intake, but 1% milk favors a lower post-meal blood glucose and average subjective appetite score and adds to nutrient intake.

Increasing salinity of freshwater from environmental and anthropogenic influences is threatening the health of 35 million inhabitants in coastal Bangladesh. Yet little is known about the characteristics of their exposure to salt (sodium), a major risk factor for hypertension and related chronic diseases. This research examined sodium consumption levels and associated factors in young adults. We assessed spot urine samples for 282 participants (19-25 years) during May-June 2014 in a rural sub-district in southwestern coastal Bangladesh and measured sodium levels of their potable water sources. The significant factors associated with high sodium consumption were determined from logistic regression analyses. Mean sodium content in tube-well water (885 mg/L) was significantly higher than pond water (738 mg/L) (P = 0.01). Fifty three percent of subjects were consuming sodium at levels above the WHO recommended level (≥2 g/day). The users of tube-well water were more likely to consume sodium above this recommended level than pond water users. Salinity problems are projected to increase with climate change, and with large populations potentially at risk, appropriate public health and behavior-change interventions are an urgent priority for this vulnerable coastal region along with targeted research to better understand sodium exposure pathways and health benefits of alternative water supplies.

Online surveys were conducted to determine the impact of endorser credibility, endorser effectiveness, and consumers' involvement in direct-to-consumer advertising. In a randomized posttest only study, using the elaboration likelihood model, survey participants (U.S. adults) were either exposed to a fictitious prescription drug ad with a celebrity or a noncelebrity endorser. There was no significant difference in credibility and effectiveness between the celebrity and the noncelebrity endorser. High involvement consumers viewed the ad more favorably and exhibited significantly stronger drug inquiry intentions during their next doctor visit. Further, consumers' involvement did not moderate the effect of celebrity endorser.

A system model for assessing vehicle use-phase water consumption in urban mobility networks

International Nuclear Information System (INIS)

Yen, Jeff; Bras, Bert

2012-01-01

Water consumption is emerging as an important issue potentially influencing the composition of future urban transportation networks, especially as projected urban populations are expected to outpace water availability and as alternative fuels and vehicles are being implemented in such regions. National and State policies aimed at reducing dependence on imported fuels and energy can increase local production of fuels and energy, impacting demand on local water resources. This article details the development of a model-based assessment on water consumption and withdrawal pertaining to the use-phase of conventional and alternative transportation modes based on regional energy and fuel production. An extensive literature review details water consumption from fuel extraction, processing, and distribution as well as power plant operations. Using Model-Based Systems Engineering principles and the Systems Modeling Language, a multi-level, multi-modal framework was developed and applied to the Metro Atlanta transportation system consisting of conventional and alternative vehicles across varying conditions. According to the analysis, vehicles powered by locally produced biofuels and electricity (assuming average local grid mix for charging) consume more water than locally refined gasoline and CNG-powered vehicles. Improvements in power plant technologies, electricity generation (e.g., use of solar and wind versus hydro power) and vehicle efficiencies can reduce such water consumption significantly. Total water withdrawal for each vehicle and fuel is significantly greater than water consumption. - Highlights: ► A model was made to assess the local water consumption due to conventional and alternatively powered vehicles in a city. ► Water consumed in the local and external production of various fuels was reviewed and included. ► Basic battery electric and biofuel powered vehicles consume on average more water than conventional gasoline and Compressed Natural Gas (CNG

The water intensity of the plugged-in automotive economy.

King, Carey W; Webber, Michael E

2008-06-15

Converting light-duty vehicles from full gasoline power to electric power, by using either hybrid electric vehicles or fully electric power vehicles, is likely to increase demand for water resources. In the United States in 2005, drivers of 234 million cars, lighttrucks, and SUVs drove approximately 2.7 trillion miles and consumed over 380 million gallons of gasoline per day. We compare figures from literature and government surveys to calculate the water usage, consumption, and withdrawal, in the United States during petroleum refining and electricity generation. In displacing gasoline miles with electric miles, approximately 2-3 [corrected] times more water is consumed (0.24 [corrected] versus 0.07--0.14 gallons/mile) and over 12 [corrected] times more water is withdrawn (7.8 [corrected] versus 0.6 gallons/mile) primarily due to increased water cooling of thermoelectric power plants to accommodate increased electricity generation. Overall, we conclude that the impact on water resources from a widespread shift to grid-based transportation would be substantial enough to warrant consideration for relevant public policy decision-making. That is not to say that the negative impacts on water resources make such a shift undesirable, but rather this increase in water usage presents a significant potential impact on regional water resources and should be considered when planning for a plugged-in automotive economy.

Direct-to-consumer advertising (DTCA) for prescription drugs: consumers' attitudes and preferences concerning its regulation in South Korea.

Suh, Hae Sun; Lee, Donghyun; Kim, Sang Yong; Chee, Dong Hyun; Kang, Hye-Young

2011-08-01

To examine consumers' attitudes toward direct-to-consumer advertising (DTCA) for prescription drugs in Korea. We conducted a survey of 350 patients visiting community pharmacies to fill their prescriptions. Consumers' attitudes toward DTCA were assessed in terms of whether they felt DTCA was necessary, their trust in the information provided by DTCA, and their intention to use the information provided by DTCA. We examined consumers' preferences regarding the regulation of DTCA and their expectations of the effects of DTCA. About 60% of the respondents responded that DTCA is necessary and that they intended to use the information from DTCA. Less than half of the respondents reported that they would trust DTCA information. About 70% of the participants expressed the need for prior vetting of the DTCA content. Respondents had the highest expectation on the effect of DTCA as an information source for patients. Positive consumer expectations regarding the effects of DTCA were significantly associated with positive consumer attitudes toward DTCA (odds ratio=4.70, 95% confidence interval: 2.25-9.82). This study provides evidence that consumers in South Korea generally have positive attitudes toward DTCA. However, most of the respondents wanted a prior examination system of DTCA content to ensure that the information conveyed to them via DTCA was trustworthy. Policy-makers should be cautious and well-prepared if they decide to introduce DTCA in Korea. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

Riska, E; Taylor, J A

1978-01-01

Consumer attitudes toward key issues affecting health policy decisions in the local community have been ignored both by local health policy makers and by medical sociologists. The authors report an empirical analysis of: (1) consumer attitudes towards federal intervention in health care; (2) consumer perceptions of the free market philosophy of health providers; (3) consumer perceptions of their involvement in health policy making; (4) consumer confidence in present systems of health services delivery; and (5) consumer awareness of recent major health legislation. It was found that consumers are poorly informed about recent health care legislation. The authors compared the attitudes of consumers with those held by local hospital board members toward health policy issues. The differences for all comparisons were statistically significant. The authors argue that hospital board members attribute problems in health services delivery to demand dysfunctions while consumers perceive the problems to be a result of supply dysfunctions. Thus, failure to include consumers on health policy boards guarantees the absence of a solution-oriented dialogue and promotes the continuing predominance of a provider-biased ideology.

This study was conducted to examine the sensory profiles of fermented soybean paste (Doenjang), to understand consumers' acceptability of different types of Doenjang samples and to identify the sensory characteristics that drive consumer acceptability of Doenjang products. Descriptive analysis and consumer acceptability test were conducted for 7 different types of Doenjang samples. The samples included 2 types of Doenjang made by either traditional or commercially modified methods. For the descriptive analysis, 8 trained panelists developed and evaluated 31 descriptors. There were significant differences in all 31 attributes among the samples. Principal component analysis was also performed to summarize the sensory characteristics of the samples. In consumer testing, 200 consumers evaluated the acceptability of Doenjang samples. Significant differences in consumer acceptability were observed among the samples. The consumers preferred the Doenjang samples manufactured using a commercially modified method. In overall point of view, most consumers liked the Doenjang samples that had strong "sweet" and "MSG (monosodium glutamate)" tastes. It appears that "sweet" and "MSG" tastes are the drivers of liking for Doenjang. "Salty" taste, "meju,"traditional Korean soy sauce," and "fermented fish" odor/flavors seem to be the drivers of disliking for Doenjang. Cluster analysis identified 3 subconsumer segments sharing a common preference pattern for the 7 samples within a cluster. The results showed that each consumer cluster preferred different Doenjang samples. External preference mapping was performed to establish the relationships between the sensory attributes and consumer acceptability in each cluster. Consumption of the fermented soybean products is gradually expanding around the world, due to their various health benefits. Therefore, understanding sensory characteristics and consumer acceptability of Doenjang are becoming increasingly important. The intense and complex

Preferences for sensory properties (e.g. taste and texture) are assumed to control cooking behaviour with respect to vegetables. Conditions such as the cooking method, amount of water used and the time-temperature profile determine the nutritional quality (e.g. vitamins and phytochemicals) of cooked vegetables. Information on domestic processing and any underlying motives can be used to inform consumers about cooking vegetables that are equally liked and are nutrient-rich. Two online self-reporting questionnaires were used to identify domestic processing conditions of broccoli and carrots by Dutch households. Questions on various aspects of domestic processing and consumer motives were included. Descriptive data analysis and hierarchical cluster analysis were performed for both vegetables, separately, to group consumers with similar motives and behaviour towards vegetables. Approximately 70% of consumers boiled vegetables, 8-9% steamed vegetables, 10-15% stir fried raw vegetables and 8-10% stir fried boiled vegetables. Mainly texture was used as a way to decide the 'doneness' of the vegetables. For both vegetables, three clusters of consumers were identified: texture-orientated, health-orientated, or taste-orientated. The texture-orientated consumers are identified as the most prevalent (56-59%) group in the present study. Statistically significant associations are found between domestic processing conditions and clusters, whereas no such association are found between demographic details and clusters. A wide variation in domestic processing of broccoli and carrots is found in the present study. Mainly sensory properties (i.e. texture and taste) determined the domestic processing conditions. The findings of the present study can be used to optimise cooking to yield vegetables that meet consumer's specific sensory preference and are higher in nutrients, and as well as to communicate with target consumer groups. © 2014 The British Dietetic Association Ltd.

A study on the effects of the CAFE standard on consumers

In this paper, we analyzed how the CAFE standard has affected improvements in the fuel economy of vehicles, as examined in other preceding studies, but in addition, we also analyzed how these standards have affected the level of consumer interest in fuel economy. Our goal was to determine what effects the government intervention has had on consumers, and whether such intervention ought to be continued. The results showed that not only has the CAFE standard had a direct and significant impact on improving fuel economy and increasing the market share of fuel-efficient vehicles, it has also boosted the development of technologies for enhancing fuel economy and raised consumer interest in fuel economy, thus indirectly contributing to overcoming market failure. The significance of this study is that we used publically available observed data and analyzed the recent impact of the CAFE standard specifically with a focus on the behavior and strategies exhibited by consumers and automakers. Another significance of this study is that it extends our purview to examine the effects that the CAFE standard has had in other countries (Korea). - Highlights: •CAFE standards have raised consumer interest in fuel economy such as MPG. •CAFE standards had a significant impact on increasing fuel-efficient vehicles •Sales of HEVs are more significantly affected by CAFE standards than by WTI. •CAFE standards had a significant impact on a foreign vehicle market. •Analysis suggests the standards will continue to be necessary for market growth.

To test a method of engaging consumers in research priority-setting using a quantitative approach and to determine consumer views on stroke research priorities for clinical practice recommendations with lower levels of evidence (Level III and Level IV) and expert consensus opinion as published in the Australian stroke clinical practice guidelines. Survey Urban community Eighteen stroke survivors (n = 12) and carers (n = 6) who were members of the "Working Aged Group - Stroke" (WAGS) consumer support group. Phase I: Participants were asked whether recommendations were "worth" researching ("yes" or "no"); and, if researched, what potential impact they likely would have on patient outcomes. Phase II: Participants were asked to rank recommendations rated by more than 75% of participants in Phase I as "worth" researching and "highly likely" or "likely" to generate research with a significant effect on patient outcomes (n = 13) in order of priority for future stroke research. All recommendations were rated by at least half (n = 9, 50%) of participants as "worth" researching. The majority (67% to 100%) rated all recommendations as "highly likely" or "likely" that research would have a significant effect on patient outcomes. Thirteen out of 20 recommendations were ranked for their research priorities. Recommendations under the topic heading Getting to hospital were ranked highest and Organization of care and Living with stroke were ranked as a lower priority for research. This study provided an example of how to involve consumers in research priority setting successfully using a quantitative approach. Stroke research priorities from the consumer perspective were different from those of health professionals, as published in the literature; thus, consumer opinion should be considered when setting research priorities.

It is generally assumed that dietary water might be beneficial for the health, especially in dermatological (age preventing) terms. The present study was designed to quantify the impact of dietary water on major indicators of skin physiology. A total of 49 healthy females (mean 24.5±4.3 years) were selected and characterized in terms of their dietary daily habits, especially focused in water consumption, by a Food Frequency Questionnaire. This allowed two groups to be set - Group 1 consuming less than 3,200 mL/day (n=38), and Group 2 consuming more than 3,200 mL/day (n=11). Approximately 2 L of water were added to the daily diet of Group 2 individuals for 1 month to quantify the impact of this surplus in their skin physiology. Measurements involving epidermal superficial and deep hydration, transepidermal water loss, and several biomechanical descriptors were taken at day 0 (T0), 15 (T1), and 30 (T2) in several anatomical sites (face, upper limb, and leg). This stress test (2 L/day for 30 days) significantly modified superficial and deep skin hydration, especially in Group 1. The same impact was registered with the most relevant biomechanical descriptors. Thus, in this study, it is clear that higher water inputs in regular diet might positively impact normal skin physiology, in particular in those individuals with lower daily water consumptions.

The Lagoa Real Uranium Province, situated in South Central Bahia in the region of Caetite and Lagoa Real, is considered the most important monomineralic province of Brazil. The urban population who lives in the proximities of this uranium province in the cities of Caetite, Lagoa Real and Livramento uses public supply water, while the inhabitants of the rural area due to long terms of dry weather use water from wells, cisterns, small dams, reservoirs and dikes which are supplied with the rains. In this work it was determined the concentration of uranium in the water consumed by the rural and urban population living in the proximities of the Lagoa Real Uranium Province. The study comprehends 32 sampling spots spread throughout the region of interest. Samples were collected in January and July 2010, covering superficial, underground and public supply water from the region. The uranium concentrations were determined by an inductively coupled plasma mass spectrometer (ICP-MS). Preliminary results showed that the uranium concentrations in the water from the Lagoa Real Uranium Province varied from 0.064 {+-} 0.005 {mu}g.L{sup -1} to 90 {+-} 1,5 {+-}g.L{sup -1}. It was observed that only two of them obtained values higher than the World Health Organization's recommended limit (2011) of 30 {mu}g.L{sup -1} for maximum uranium concentration in the water for human consumption. For a conclusive evaluation, the uranium concentrations results will be analyzed together with total alpha and beta concentrations determined elsewhere for the same samples. (author)

During postprandial state, TG concentration is increasing and HDL cholesterol decreasing, leading to a transitory pro-atherosclerotic profile. Previous studies have reported that bicarbonate water improve postprandial lipemia. The objective of this study was to analyze the effect of a strongly bicarbonated mineral water on lipoprotein levels during fasting and postprandial state. A controlled, randomised, double-blind cross-over design was conducted in 12 moderately hypercholesterolemic subjects after a daily ingestion of 1.25 L of mineral (SY) or low mineral water during eight weeks separated by a one week wash-out period. Blood samples were collected in first visit to the hospital (V1) before water consumption (referent or SY) and in a second visit (V2) after eight week water consumption period. The effect of the consumed water was studied in fasting and in postprandial state during ingestion of a meal and 0.5 L of water. Comparison of data between V1 and V2 after SY consumption showed a significant decrease in triglyceridemia (23%), VLDL TG (31%) and tendency to a decrease of VLDL cholesterol (p = 0.066) at fasting state. Whatever the consumed water during postprandial state, the measurement of total areas under curves did not show a significant difference. No difference was observed between SY and referent water consumption for measured parameters at fasting and postprandial state. When subjects consumed SY we showed a decrease of their basal TG and VLDLTG. The unexpected absence of effect of high mineralized water on postprandial lipemia, probably related to experimental conditions, is discussed in the discussion section.

2010-09-01

Full Text Available Abstract Background The present study sought to determine whether the consumption of a mineral-rich alkalizing (AK bottled water could improve both acid-base balance and hydration status in young healthy adults under free-living conditions. The AK water contains a naturally high mineral content along with Alka-PlexLiquid™, a dissolved supplement that increases the mineral content and gives the water an alkalizing pH of 10.0. Methods Thirty-eight subjects were matched by gender and self-reported physical activity (SRPA, hrs/week and then split into Control (12 women, 7 men; Mean +/- SD: 23 +/- 2 yrs; 7.2 +/- 3.6 hrs/week SRPA and Experimental (13 women, 6 men; 22 +/- 2 yrs; 6.4 +/- 4.0 hrs/week SRPA groups. The Control group consumed non-mineralized placebo bottled water over a 4-week period while the Experimental group consumed the placebo water during the 1st and 4th weeks and the AK water during the middle 2-week treatment period. Fingertip blood and 24-hour urine samples were collected three times each week for subsequent measures of blood and urine osmolality and pH, as well as total urine volume. Dependent variables were analyzed using multivariate repeated measures ANOVA with post-hoc focused on evaluating changes over time within Control and Experimental groups (alpha = 0.05. Results There were no significant changes in any of the dependent variables for the Control group. The Experimental group, however, showed significant increases in both the blood and urine pH (6.23 to 7.07 and 7.52 to 7.69, respectively, a decreased blood and increased urine osmolality, and a decreased urine output (2.51 to 2.05 L/day, all during the second week of the treatment period (P Conclusions Consumption of AK water was associated with improved acid-base balance (i.e., an alkalization of the blood and urine and hydration status when consumed under free-living conditions. In contrast, subjects who consumed the placebo bottled water showed no changes over the

Consumers Union, publisher of Consumer Reports magazine, has used the drug class reviews of the Drug Effectiveness Review Project (DERP) as one critical component of a free public information project on the comparative effectiveness, safety, and cost of prescription drugs. The project translates the DERP findings for consumers. Drawing on other sources and adding information on drug costs, the project chooses Best Buy drugs in each category it evaluates. This guidance can help consumers save up to thousands of dollars per year, and it has the potential to reduce overall drug spending.

Meeting everyday water needs--a company's contribution.

Duncan, D

2004-01-01

As a packaged consumer goods company serving mass markets around the world for household and personal hygiene products, laundry detergents and foods, Unilever's business is inextricably linked with consumers' interest in meeting their everyday water needs. Once the basic need for drinking water is met, almost all other "everyday" water needs derive from consumption associated with the type of products Unilever sells. Use of some of these products, such as basic toilet soap, involve "actual" water consumption; others, such as margarine, concern "virtual" water consumption through agricultural production. Global scenarios for water and sanitation present a major challenge to long-term business strategies that assume sustained economic growth particularly in emerging and developing markets. Responsibility for finding and delivering solutions lies with all major actors in society. For companies such as Unilever, a priority is to help break the link between economic development on the one hand, and increased water use and water degradation on the other. Water catchment level perspectives are central to realising this vision. Unilever uses such a framework, building an experience-based model that demonstrates how a "consumer" company can engage in meeting everyday water needs with a sustained positive impact.

ACCEPTANCE OF FUNCTIONAL FOOD AMONG CHILEAN CONSUMERS: APPLE LEATHER.

2015-10-01

the aim of this study is to measure acceptance of a specific functional food: apple (fruit) leather, based on organoleptic characteristics and to identify consumer types and preferences for natural additives which increase the product's functionality and meet current nutritional needs. a sample of 800 consumers provided an evaluation of apple leather in terms of acceptance (liking). A sensorial panel was carried out using a 9-point hedonic scale. Cluster analysis was used to identify different acceptance-based consumer types. In addition, a conjoint analysis was carried out to determine preference for different additives. the cluster analysis resulted in four groups with significant differences in the average likings obtained from the sensory panel. Results indicate that the sweetness of the tested apple leather was evaluated best among all groups and, on average, color was rated as the worst attribute. However, overall likings differ significantly between groups. Results from the conjoint analysis indicate that, in general, consumers prefer natural additives included in the product which enhance functionality. although there is a "global acceptance" of the product, there are significant differences between groups. The results of the conjoint analysis indicate that, in general, consumers prefer the aggregation of natural additives which increase the product's functionality. Apple leather with natural additives, such as anticariogenics and antioxidants, can be considered a functional substitute of unhealthy snacks and/or sweets. Copyright AULA MEDICA EDICIONES 2014.

2015-03-01

Individuals who undergo multiplex direct-to-consumer (DTC) genomic testing receive genetic risk results for multiple conditions. To date, research has not investigated the influence of individual differences in disease perceptions among consumers on testing outcomes. A total of 2037 participants received DTC genomic testing and completed baseline and follow-up surveys assessing disease perceptions and health behaviors. Participants were asked to indicate their most feared disease of those tested. Perceived seriousness and controllability of the disease via lifestyle or medical intervention were assessed. Participants most frequently reported heart attack (19.1%) and Alzheimer's disease (18.6%) as their most feared disease. Perceived seriousness and control over the feared disease both influenced response to DTC genomic testing. Greater perceived seriousness and diminished perceived control were associated with higher, but not clinically significant levels of anxiety and distress. In some cases these associations were modified by genetic risk. No significant associations were observed for diet, exercise and screening behaviors. Individual differences in disease perceptions influence psychological outcomes following DTC genomic testing. Higher perceived seriousness may make a consumer more psychologically sensitive to test results and greater perceived control may protect against adverse psychological outcomes. Findings may inform development of educational and counseling services. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Yin, Shijiu; Wu, Linhai; Du, Lili; Chen, Mo

2010-06-01

The global market for organic food has developed significantly in the past decade. The organic food industry in China is export oriented, with production growing rapidly, although the domestic market remains relatively small. This paper surveys 432 consumers from three cities in China, consequently establishing a logit model to analyse the main factors affecting consumers' choice for organic food. The result indicates that Chinese consumers' intent to purchase organic food is strongly affected by factors such as income, degree of trust in organic food, degree of acceptance of organic food price, and consumers' concern on self-health. This intent is only slightly affected by factors such as consumers' age, education level and concern about environmental protection. Based on the results, the following measures are recommended: reduce the cost of organic food through multiple channels to cut down the market price; establish and perfect the supervision system of organic food; and promote organic food through various channels.

Full Text Available Consumers are considered, within the European vision, the “life force” of the economy. Although the technological means are increasingly available, both European SMEs and consumers are still suspicious of conducting cross-border trade. Single European market has the potential to become the largest market in the world. Currently, it remains largely fragmented along national borders, forming 27 mini-markets. The European Commission’s aim is to achieve a more integrated internal market such that consumers from each Member State have an equally high level of confidence in products, traders, selling methods, as well as consumer protection – no matter where they decide to make their purchases within the EU. The paper presents a secondary analysis of data regarding the many differences in terms of Europeans’ consumption patterns for different product categories (as a percentage of total expenditures. For example, the share of household budget used to purchase food is highest in our country and lowest in Luxembourg.. Also, the largest proportion of family budget allocated for utilities (water, electricity, gas we find in Bulgaria, and for cultural activities – in Austria.

As a result of the digital revolution coming to medicine, a number of new tools are becoming available and are starting to be introduced in clinical practice. We aim to assess health care professional and consumer attitudes toward new medical technology including smartphones, genetic testing, privacy, and patient-accessible electronic health records. We performed a survey with 1406 health care providers and 1102 consumer responders. Consumers who completed the survey were more likely to prefer new technologies for a medical diagnosis (437/1102, 39.66%) compared with providers (194/1406, 13.80%; P<.001), with more providers (393/1406, 27.95%) than consumers (175/1102, 15.88%) reporting feeling uneasy about using technology for a diagnosis. Both providers and consumers supported genetic testing for various purposes, with providers (1234/1406, 87.77%) being significantly more likely than consumers (806/1102, 73.14%) to support genetic testing when planning to have a baby (P<.001). Similarly, 91.68% (1289/1406) of providers and 81.22% (895/1102) of consumers supported diagnosing problems in a fetus (P<.001). Among providers, 90.33% (1270/1406) were concerned that patients would experience anxiety after accessing health records, and 81.95% (1149/1406) felt it would lead to requests for unnecessary medical evaluations, but only 34.30% (378/1102; P<.001) and 24.59% (271/1102; P<.001) of consumers expressed the same concerns, respectively. Physicians (137/827, 16.6%) reported less concern about the use of technology for diagnosis compared to medical students (21/235, 8.9%; P=.03) and also more frequently felt that patients owned their medical record (323/827, 39.1%; and 30/235, 12.8%, respectively; P<.001).

Full Text Available This paper illustrates the utility of multivariate statistical techniques for analysis and interpretation of water quality data sets and identification of pollution sources/factors with a view to get better information about the water quality and design of monitoring network for effective management of water resources. Multivariate statistical techniques, such as factor analysis (FA/principal component analysis (PCA and cluster analysis (CA, were applied for the evaluation of variations and for the interpretation of a water quality data set of the natural water bodies obtained during 2010 year of monitoring of 13 parameters at 33 different sites. FA/PCA attempts to explain the correlations between the observations in terms of the underlying factors, which are not directly observable. Factor analysis is applied to physico-chemical parameters of natural water bodies with the aim classification and data summation as well as segmentation of heterogeneous data sets into smaller homogeneous subsets. Factor loadings were categorized as strong and moderate corresponding to the absolute loading values of >0.75, 0.75-0.50, respectively. Four principal factors were obtained with Eigenvalues >1 summing more than 78 % of the total variance in the water data sets, which is adequate to give good prior information regarding data structure. Each factor that is significantly related to specific variables represents a different dimension of water quality. The first factor F1 accounting for 28 % of the total variance and represents the hydrochemical dimension of water quality. The second factor F2 accounting for 18% of the total variance and may be taken factor of water eutrophication. The third factor F3 accounting 17 % of the total variance and represents the influence of point sources of pollution on water quality. The fourth factor F4 accounting 13 % of the total variance and may be taken as an ecological dimension of water quality. Cluster analysis (CA is an

Water-resistant sunscreens for skin protection: an in vivo approach to the two sources of sunscreen failure to maintain UV protection on consumer skin.

2015-12-01

The water resistance of sunscreen products has taken more importance for the UV protection of consumers involved in water activities and sports. The present work introduces a new in vivo approach to measure the water resistance of sunscreens on the actual skin of subjects, which can be easily applied to salt, chlorine and tap waters. The stress sources of sunscreen films on skin originate from two phenomena: high surface tension stress as the skin transits through the air/water interface and water diffusion into the film immersed in bulk water. The water resistance of sunscreen products is measured on the forearms of subjects by means of a new layered water bath approach that physically separates both stresses. Tape strips are subsequently taken and analysed for UV-A and UV-B optical densities via (1) imaging for remaining filters and (2) in vitro SPF absorption spectra. Water-resistant sunscreens generally perform well when immersed in bulk water even subjected to agitation, but they show a wide range of performances when considering their behaviour at the air/water interface. The differences are more pronounced in salt water than tap water. The results confirm 2 stress origins in sunscreen exposure to water: interfacial surface tension and bulk water diffusion. Polymers bring improvements to the resistance of sunscreens to bulk water but show wide latitude in performances when subject to the water surface tension stress. Globally, a higher loss of filters is observed in the UV-A than in the UV-B, which is attributed to more UV-A filter loss or degradation and thus resulting in a decreased protection in the UV-A. © 2015 Society of Cosmetic Scientists and the Société Française de Cosmétologie.

Public health significance of zoonotic Cryptosporidium species in wildlife: Critical insights into better drinking water management.

Science.gov (United States)

Zahedi, Alireza; Paparini, Andrea; Jian, Fuchun; Robertson, Ian; Ryan, Una

2016-04-01

Cryptosporidium is an enteric parasite that is transmitted via the faecal-oral route, water and food. Humans, wildlife and domestic livestock all potentially contribute Cryptosporidium to surface waters. Human encroachment into natural ecosystems has led to an increase in interactions between humans, domestic animals and wildlife populations. Increasing numbers of zoonotic diseases and spill over/back of zoonotic pathogens is a consequence of this anthropogenic disturbance. Drinking water catchments and water reservoir areas have been at the front line of this conflict as they can be easily contaminated by zoonotic waterborne pathogens. Therefore, the epidemiology of zoonotic species of Cryptosporidium in free-ranging and captive wildlife is of increasing importance. This review focuses on zoonotic Cryptosporidium species reported in global wildlife populations to date, and highlights their significance for public health and the water industry.

Pollution source localization in an urban water supply network based on dynamic water demand.

Science.gov (United States)

Yan, Xuesong; Zhu, Zhixin; Li, Tian

2017-10-27

Urban water supply networks are susceptible to intentional, accidental chemical, and biological pollution, which pose a threat to the health of consumers. In recent years, drinking-water pollution incidents have occurred frequently, seriously endangering social stability and security. The real-time monitoring for water quality can be effectively implemented by placing sensors in the water supply network. However, locating the source of pollution through the data detection obtained by water quality sensors is a challenging problem. The difficulty lies in the limited number of sensors, large number of water supply network nodes, and dynamic user demand for water, which leads the pollution source localization problem to an uncertainty, large-scale, and dynamic optimization problem. In this paper, we mainly study the dynamics of the pollution source localization problem. Previous studies of pollution source localization assume that hydraulic inputs (e.g., water demand of consumers) are known. However, because of the inherent variability of urban water demand, the problem is essentially a fluctuating dynamic problem of consumer's water demand. In this paper, the water demand is considered to be stochastic in nature and can be described using Gaussian model or autoregressive model. On this basis, an optimization algorithm is proposed based on these two dynamic water demand change models to locate the pollution source. The objective of the proposed algorithm is to find the locations and concentrations of pollution sources that meet the minimum between the analogue and detection values of the sensor. Simulation experiments were conducted using two different sizes of urban water supply network data, and the experimental results were compared with those of the standard genetic algorithm.

Shakeel Ahmad Sofi

2017-06-01

Full Text Available The primary aim of the current research was to study the effect of various intrinsic factors on consumer decision making vis-à-vis impulsive buying tendencies. After employing EFA and CFA on 630 consumers in the different parts of Jammu and Kashmir, results showed that intrinsic factors significantly influence the Impulsive Buying Decision. The application of Structural Equation Modeling disintegrated intrinsic factors into positive and negative influencers of impulsive buying behaviour. The present study has significant bearing in consumer world as it has highlighted through a model for how intrinsic factors shape the buying tendencies of a young consumer. Through the application of Multi Group Analysis, a comparison has been drawn between impulsive buying behaviour and various intrinsic factors across males and females taken as two different consumer groups. Overall results have been found significant and could well be adopted for strategy making by various stake holders in the field of consumer psychology and consumer behaviour to figure out the effects of intrinsic factors on buying behaviour.

Urban community perception towards intermittent water supply system.

Joshi, M W; Talkhande, A V; Andey, S P; Kelkar, P S

2002-04-01

While evaluating intermittent and continuous water supply systems, consumers opinion survey was undertaken for critical appraisal of both modes of operation. With the help of a pre-designed set of questions relating to various aspects of water supply and the opinion of consumers regarding degree of service, a house to house survey was conducted in the study area of Ghaziabad and Jaipur. The consumer opinion survey clearly indicated a satisfactory degree of service wherever adequate quantity of water was made available irrespective of the mode of water supply. Number of complaints regarding quality of water supplied, timings of supply, low pressures and breakdowns in supply were reported during intermittent water supply. Every family stored water for drinking and other uses. Most of the families discard drinking water once the fresh water supply is resumed next day. Discarded drinking water is usually used in kitchen for washing and gardening. Storage for other purposes depends on economic status and availability of other sources like open dug well in the house. While most of the respondents had no complaints on water tariff, all of them were in favour of continuous water supply.

Predicting consumers' intention to consume ready-to-eat meals. The role of moral attitude.

Science.gov (United States)

Olsen, Nina Veflen; Sijtsema, Siet J; Hall, Gunnar

2010-12-01

This study investigates the usefulness of integrating moral attitude into the Theory of Planned Behavior (TPB) model when predicting intention to consume ready-to-eat (RTE) meals. Questionnaire data were gathered in three countries: Norway (N = 112), The Netherlands (N = 99), and Finland (N = 134) in spring 2009. A stepwise hierarchical regression was conducted, and the analyses showed that moral attitude is an important predictor of RTE-meal consumption. The feeling of moral obligation, operationalised as a negative feeling of guilt, had a negative effect on peoples' intention to consume ready meals in all the three countries tested, and the explained variance (R²) for TPB increased when moral was added as an explanatory factor. However, although the test showed significant results for the effect of attitude towards behavior and moral in all countries, non-significant results were observed for the effect of subjective norm in both The Netherlands and Norway when moral attitude was included to the TPB-model, indicating cultural differences in the social pressure towards ready meal consumption.

Management of drinking water quality in Pakistan

International Nuclear Information System (INIS)

Javed, A.A.

2003-01-01

Drinking water quality in both urban and rural areas of Pakistan is not being managed properly. Results of various investigations provide evidence that most of the drinking water supplies are faecally contaminated. At places groundwater quality is deteriorating due to the naturally occurring subsoil contaminants, or by anthropogenic activities. The poor bacteriological quality of drinking water has frequently resulted in high incidence of water borne diseases while subsoil contaminants have caused other ailments to consumers. This paper presents a detailed review of drinking water quality in the country and the consequent health impacts. It identifies various factors contributing to poor water quality and proposes key actions required to ensure safe drinking water supplies to consumers. (author)

We evaluated the current literature, coupled with our collective research expertise, on surface-water connectivity of wetlands considered to be “geographically isolated” (sensu Tiner Wetlands 23:494–516, 2003a) to critically assess the scientific foundation of grouping wetlands based on the singular condition of being surrounded by uplands. The most recent research on wetlands considered to be “geographically isolated” shows the difficulties in grouping an ecological resource that does not reliably indicate lack of surface water connectivity in order to meet legal, regulatory, or scientific needs. Additionally, the practice of identifying “geographically isolated wetlands” based on distance from a stream can result in gross overestimates of the number of wetlands lacking ecologically important surface-water connections. Our findings do not support use of the overly simplistic label of “geographically isolated wetlands”. Wetlands surrounded by uplands vary in function and surface-water connections based on wetland landscape setting, context, climate, and geographic region and should be evaluated as such. We found that the “geographically isolated” grouping does not reflect our understanding of the hydrologic variability of these wetlands and hence does not benefit conservation of the Nation’s diverse wetland resources. Therefore, we strongly discourage use of categorizations that provide overly simplistic views of surface-water connectivity of wetlands fully embedded in upland landscapes.

2004-01-01

Full Text Available The consumption of drinking water for a community is different from one area to the other. This is normally influenced by the population development, socio-economic, cultural, and physical conditions mainly related to the supply of drinking water and how to exploit it. Banyudono district is an area located in the regency of Boyolali. The development of this area depends on Boyolali City and Kartasura district. Such a location enables the area to have a process of the physical and socio-economi developments. In addition, it has an influence upon social behaviour to consume water. This research is aimed at knowing the average consumption of household need and analyzing the factors influencing the utilization of water as drinking water. The result of this research indicated that 1 the average consumption of a human being for drinking water was 79,37 litter a day. It means that the onsumption of a human being for drinking ater generally ranged from 60 to 80 litter a day; 2 most of the ater was consumed to meet basic needs such as cooking, drinking, bathing, and washing; 3 the difference of the average consumption was influenced by the kind of water source and how to exploit it; 4 a parameter of the most significant socio-economic condition that took effect on the average consumption for drinking water was the parameter of income with correlation of 0.362 and the significant level of 0.01.

To study differences in the role of price and value in food choice between low-income and higher-income consumers and to study the perception of consumers about pricing strategies that are of relevance during grocery shopping. A cross-sectional study was conducted using structured, written questionnaires. Food choice motives as well as price perceptions and opinion on pricing strategies were measured. The study was carried out in point-of-purchase settings, i.e. supermarkets, fast-food restaurants and sports canteens. Adults (n 159) visiting a point-of-purchase setting were included. Price is an important factor in food choice, especially for low-income consumers. Low-income consumers were significantly more conscious of value and price than higher-income consumers. The most attractive strategies, according to the consumers, were discounting healthy food more often and applying a lower VAT (Value Added Tax) rate on healthy food. Low-income consumers differ in their preferences for pricing strategies. Since price is more important for low-income consumers we recommend mainly focusing on their preferences and needs.

The significance of natural ground-water recharge in site selection for mill tailings disposal

International Nuclear Information System (INIS)

Stephens, D.B.

1985-01-01

Milling operations throughout the world have created vast amounts of waste by-products, or tailings, which are often disposed on the land surface. The wastes may be disposed behind dams, on untreated ground, or on compacted clay or synthetic liners of impoundments and trenches. Often one of the principle concerns of environmental regulatory agencies is whether seepage from the waste pile could move through the vadose zone to the water table and possibly contaminate an aquifer. The seepage may be generated by the drainage of liquids initially deposited along with the tailings or by infiltrating meteoric water which leaches soluted from the tailings. The purpose of this article is to discuss some of the commonly held assumptions regarding storage of seepage wastes in the unsaturated zone. The significance of recent studies of water movement in dry climates which pertain to tailings site selection are presented

Attitudes of Turskish Consumers toward Advertising through Sport among the Question how often Consumers purchase Sporting Goods

Directory of Open Access Journals (Sweden)

Gorica Zoric

2017-08-01

Full Text Available Unlike other advertising mediums such as TV commercials or online advertising, people involuntarily receive sport advertisements; they prefer to watch the game for the sporting action than the regular advertisements. However, it is important to analyse their general attitudes among various questions, mostly due to the reason it varies from demographic group to demographic group. Hence, this research was aimed at gaining relevant knowledge about the attitudes of Serbian consumers toward advertising through sport among the question how often consumers purchase sporting goods. The sample included 173 respondents, divided into six subsample groups: consumers who do not purchase sport goods at all, then consumers who purchase sport goods less than ones a month, next 1–3 a month, 4–6 a month, 7–9 a month, as well as consumers who purchase sport goods more than 10 times a month. The sample of variables contained the system of three general attitudes which were modelled by seven-point Likert scale. The results of the measuring were analysed by multivariate analysis (MANOVA and univariate analysis (ANOVA and Post Hoc test. Based on the results it was concluded that significant differences occur at multivariate level, as well as between one of three variables at univariate level (p=.05. It is interesting to highlight that most of potential consumers (n=146 have recognized themselves in two categories: as consumers who purchase sport goods less than ones a month and one to three times a months, while there were no differences among the groups. If we take a look into previous investigations, it is interesting there are some opposite results, and the recommendations for further research are directed to spread out the sample a little bit more, mostly due to the reason the consumers who had a more negative attitudes were in the group that didn’t purchase the sport goods at all.

Consumer attitudes and olive oil acceptance: The potential consumer

McEwan, Jean A.

1994-04-01

Full Text Available       This paper outlines the results of consumer research to investigate consumer attitudes towards olive oil, and to evaluate selected experimental samples for acceptability.
      Consumer focus group discussions were used to investigate consumer attitudes to and awareness of olive oil, in relation to other culinary oils. A wide range of information was obtained, indicating the increasing importance of olive oil in the UK.
       Product use was examined to investigate the different types of olive oils consumers use, and the importance of different attributes for purchase. Price, quality and colour were the most important considerations for purchasing an olive oil, whilst package design, package material and brand were the least important.       Eight samples of virgin olive oil were evaluated for acceptability of appearance, odour, flavour and mouthfeel. These data indicated clear differences in acceptability between the samples, particularly on flavour, mouthfeel and overall acceptability. These data were then linked to sensory information to determine the characteristics of oil associated with liking for the product.

Ethnocentrism, Religiosity, Environmental and Health Consciousness: Motivators for Anti-Consumers

Directory of Open Access Journals (Sweden)

Ramazan KAYNAK

2011-11-01

Full Text Available This paper covers highlighting the importance of anti-consumer groups in today’s markets and several outstanding factors shaping their reaction against consumption, which are ethnocentrism, religiosity, environmental and health consciousness. A conceptual model is presented which examines the explaining power of ethnocentrism, religiosity, environmental and health consciousness upon voluntary simplifiers and global impact consumers. Data were collected through an e-questionnaire by sending posts to the anti-consumer websites. A total of 503 useable responses were retained for analysis. The analysis reveals that ethnocentrism, environmental and health consciousness have significant impacts upon anti-consumers. In addition, religiosity has a negative impact upon global impact consumers’ anti-consumption behavior. Raising sensitiveness to environmental and health consciousness and ethnocentrism with regards to dealing with anti-consumers enables companies to have sustainable competitive power. These consumers’ growing satisfaction contributes to consumer loyalty in addition to an increase in market share. Researches related to anti-consumers have traditionally emphasized their impacts upon companies’ profits and reputation. On the contrary, this study reveals the main motivations behind voluntary simplifiers and global impact consumers and puts forth a new perspective by presenting the findings related to anti-consumers in Turkey.

Tanenbaum, Sandra J

2011-01-01

This research compares two types of consumer organizations in one state in order to explore the significance of organizational independence for internal structure/operations and external relationships. The first type, consumeroperated service organizations (COSOs), are independent and fully self-governing; the second are peer-support service organizations (PSSOs), which are part of larger non-consumer entities. Mail surveys were completed by COSO and PSSO directors of a geographically representative sample of organizations; telephone interviews were conducted with a sub-sample. Owing to small sample size, matched COSO-PSSO pairs were analyzed using non-parametric statistics. COSOs and PSSOs are similar in some ways, e.g., types of services provided, but significantly different on internal variables, such as budget size, and external variables, such as number of relationships with community groups. Organizational independence appears to be a significant characteristic for consumer service organizations and should be encouraged by funders and among participants. Funders might establish administrative and/or programmatic measures to support consumer organizations that are independent or moving toward independence; their participants would also benefit from the provision, by authorities or advocates, of materials to guide organizations toward, for example, 501(c)3 status.

Emulsion oil droplet size significantly affects satiety: A pre-ingestive approach.

Science.gov (United States)

Lett, Aaron M; Norton, Jennifer E; Yeomans, Martin R

2016-01-01

Previous research has demonstrated that the manipulation of oil droplet size within oil-in-water emulsions significantly affects sensory characteristics, hedonics and expectations of food intake, independently of energy content. Smaller oil droplets enhanced perceived creaminess, increased Liking and generated greater expectations of satiation and satiety, indicating that creaminess is a satiety-relevant sensory cue within these systems. This paper extends these findings by investigating the effect of oil droplet size (d4,3: 2 and 50 μm) on food intake and appetite. Male participants (n = 34 aged 18-37; BMI of 22.7 ± 1.6 kg/m(2); DEBQ restricted eating score of 1.8 ± 0.1.) completed two test days, where they visited the laboratory to consume a fixed-portion breakfast, returning 3 h later for a "drink", which was the emulsion preload containing either 2 or 50 μm oil droplets. This was followed 20 min later with an ad libitum pasta lunch. Participants consumed significantly less at the ad libitum lunch after the preload containing 2 μm oil droplets than after the 50 μm preload, with an average reduction of 12% (62.4 kcal). Despite the significant differences in intake, no significant differences in sensory characteristics were noted. The findings show that the impact that an emulsion has on satiety can be enhanced without producing significantly perceivable differences in sensory properties. Therefore, by introducing a processing step which results in a smaller droplets, emulsion based liquid food products can be produced that enhance satiety, allowing covert functional redesign. Future work should consider the mechanism responsible for this effect. Copyright © 2015 Elsevier Ltd. All rights reserved.

The aim of the European research project COSUS (Consumers in a sustainable food supply chain) was to increase consumer acceptance of suboptimal food, before and after purchase, by implementing targeted strategies that are based on consumer insights, and that are feasible for and acceptable by the food sector. To reach this aim, different methodological approaches were applied to analyze this issue, to experiment with different aspects, and to test the resulting interventions. Each of these approaches was undertaken by competent consortium partners from Denmark, Germany, Norway, Sweden and The Netherlands. The project finally provides validated strategies to promote the distribution and consumption of suboptimal foods, thereby improving resource efficiency in the food chain and contributing to a more sustainable food supply.

. Third, trust research in the medical context lacks empirical behavioral and neuroscientific evidence. Neurologists entering this field of research could profit from the extensive knowledge of the biological foundation of trust that scientists in economically-orientated neurosciences have gained. Fourth, neurologists could contribute significantly to the ethical debate about invasive methods in neuromarketing and consumer neuroscience. Further, neurologists should investigate biological and behavioral reactions of neurological patients to marketing and advertising measures, as they could show special consumer vulnerability and be subject to target marketing.

Direct-to-consumer advertising (DTCA) of prescription drugs in the United States is controversial. Underlying the debate are disagreements over the role of consumers in medical decision making, the appropriateness of consumers engaging in self-diagnosis, and the ethics of an industry promoting potentially dangerous drugs. Drug advertising and federal policy governing drug advertising have both responded to and reinforced changes in the consumer's role in health care and in the doctor-patient relationship over time. This article discusses the history of DTCA in the context of social movements to secure rights for health care patients and consumers, the modern trend toward consumer-oriented medicine, and the implications of DTCA and consumer-oriented medicine for contemporary health policy debates about improving the health care system.

LOW INCOME CONSUMERS AND ONLINE SHOPPING: APPREHENSIONS IN CONSUMING THROUGH THE INTERNET

Directory of Open Access Journals (Sweden)

Juan Pablo da Silva Dias

2015-08-01

Full Text Available The growth in access of low income consumers to the internet has taken them to use the net in search of entertainment, education and relationships. However, consuming online is still an activity surrounded by distrust. The present study aims to discuss the reasons why low income consumers have apprehension in consuming through the internet. For this, in depth interviews were conducted with 23 low income consumers. The collected data shows that the internet is still seen by the interviewees as being, mainly, for leisure and entertainment. Online shopping still is a task they fear, because of different motives. Initially, one can point the preference to consume in physical stores, since the consumers can touch the desired product, enjoy the trip to the store as a moment of pleasure and the possibility of interacting with salesmen, who help them in their choice. The apprehensions in buying online are also influenced by the perception that sites are not safe, because they offer threats, such as viruses or theft of personal information. Furthermore, interviewees believe that online stores are not compromised with their customers, since they permit problems to occur in the delivery of merchandise, are not clear about the shopping process, and create difficulties in payment method. Another reason for them not to buy online is the perception that if a negative consuming episode of online shopping happened to someone they know, it is also bound to happen with them. Despite this reasoning, these consumers point the importance of help from a third party in their reference group as main incentive for them to face the obstacles to consuming through the internet. In conclusion, it is possible to consider that low income consumers have apprehensions that are similar to their higher income peers, but, also, show different feelings, which are seldom discussed in the literature about online shopping.

Full Text Available Today, comprehending consumer behavior is becoming dynamically challenging with the emergence of social commerce. Business organizations are now striving to convince consumers by exploiting the advantage of social support empowered by online social networks. Importantly, social ties in such online social networks facilitate trust as the most compelling benefit while alleviating the perceived risk, which happened to be the major concerns with electronic commerce over the years. This research study is aimed at understanding the impact of social commerce on the consumer behavior, particularly consumer decision-making stages. Hence, this research was conducted as a quantitative study involving a cross-sectional survey and gathered valid responses from Facebook users. Structural Equation Modeling (SEM was used to analyze data and test hypotheses. The findings exhibited significant positive effects from social commerce on all the consumer decision-making stages namely; need recognition, information search, alternative evaluation, purchase decision and post-purchase decision. Therefore, this study highlights the importance of employing an appropriate social commerce strategy for business organizations.

Attention has been focused on the issue of radon in drinking water by a European Commission recommendation proposing that surveys should be undertaken in Member States to determine the scale and nature of exposures caused by radon in domestic drinking water supplies. The Commission recommends 1000 Bq/l as the radon activity concentration in private drinking water supplies above which remedial action to reduce the concentration should be taken. The logic behind the proposed action level is that it would broadly correspond to the risk posed to an individual from exposure to radon in the home at the current Reference Level of 200 Bq/m3 in air. A pilot study to assess the distribution and concentrations of radon in private ground water supplies was recently completed in Co. Wicklow. County Wicklow was selected for the study primarily on the basis that the underlying geology is predominantly granite with elevated uranium content. Furthermore, there is an estimated 1200 to 5000 private ground water supplies in use in the county and high radon activity concentrations in air in a significant number of dwellings have previously been predicted. As part of the pilot study, a number of scientific issues were addressed in order to underpin the results obtained and these are also discussed in the report. Radon activity concentrations were measured in the private ground water supplies of 166 houses in Co. Wicklow. In all cases the ground water was the principal source of drinking water for the house occupants. Four supplies had activity concentrations in excess of the Recommended EC action level of 1000 Bq/l, fifteen had activity concentrations between 500 and 1000 Bq/l, 51 were between 100 and 500 Bq/l and 96 had activity concentrations below 100 Bq/l. The doses estimated for the ingestion of radon bearing water vary significantly with the quantity of drinking water consumed and the degree to which the water has been processed prior to consumption.

The Anatomy of the Long Tail of Consumer Demand

Science.gov (United States)

Broder, Andrei

The long tail of consumer demand is consistent with two fundamentally different theories. The first, and more popular hypothesis, is that a majority of consumers have similar tastes and only few have any interest in niche content; the second, is that everyone is a bit eccentric, consuming both popular and niche products. By examining extensive data on user preferences for movies, music, web search, and web browsing, we found overwhelming support for the latter theory. Our investigation suggests an additional factor in the success of "infinite-inventory" retailers such as Netflix and Amazon: besides the significant revenue obtained from tail sales, tail availability may boost head sales by offering consumers the convenience of "one-stop shopping" for both their mainstream and niche interests.

A run-around heat exchanger system to improve the energy efficiency of a home appliance using hot water

International Nuclear Information System (INIS)

Park, Jae Sung; Jacobi, Anthony M.

2009-01-01

A significant portion of the energy consumed by many home appliances using hot water is used to heat cold supply water. Such home appliances generally are supplied water at a temperature lower than the ambient temperature, and the supply water is normally heated to its maximum operating temperature, often using natural gas or an electrical heater. In some cases, it is possible to pre-heat the supply water and save energy that would normally be consumed by the natural gas or electrical heater. In order to save the energy consumed by an appliance using water heater, a run-around heat exchanger system is used to transfer heat from the ambient to the water before an electrical heater is energized. A simple model to predict the performance of this system is developed and validated, and the model is used to explore design and operating issues relevant to the run-around heat exchanger system. Despite the additional power consumption by the fan and pump of the run-around heat exchanger system, the experimental data and analysis show that for some systems the overall energy efficiency of the appliance can be improved, saving about 6% of the energy used by the baseline machine.

Key Factors Determining the Ethnocentric Tendencies of Consumers in Serbia

Directory of Open Access Journals (Sweden)

Dragana Gašević

2017-11-01

Full Text Available Ethnocentric behaviour of consumers is related to the attitude and intentions of consumers when deciding upon purchasing a product, i.e., it is such a kind of behaviour which implies giving priority to purchasing domestic rather than foreign products. The results of a large number of studies show that not all consumers are equally ethnocentric. Therefore, it is of utmost significance to realize that consumers rely on various signals and make different decisions depending on their inclinations towards consumer ethnocentrism. The aim of this paper is to examine the influence and interaction of demographic characteristics of respondents in Serbia on consumer ethnocentrism. Several statistical techniques that provided support during the testing of research hypotheses have been applied in the preparation of this paper. We used nonparametric techniques (Mann-Whitney U test and Kruskal-Wallis test. The results indicate that men are more ethnocentric than women, as well as persons with lower level of education than those with higher level of education. Also, the results have shown that respondents who achieve the highest level of income are not ethnocentric in the least. In addition, it has been established that there is no statistically significant impact of the criteria of the year on the level of consumer ethnocentrism. The research results provide useful information for marketers and managers of companies that currently operate or are planning to enter Serbian market in the forthcoming period. Another great benefit is reflected in the fact that these results draw the managers’ attention to the fact which consumer groups are the most ethnocentric and thus allow the creation of high quality strategies.

Consumer energy conservation options - professional and consumer perspectives

The objectives of this study were to: identify government policies for reducing Canadian consumption of home heating fuel, electricity, and gasoline; assess probable effectiveness of different policy alternatives as a means of reducing consumer energy consumption; and measure the acceptability to Canadian consumers of the different policy alternatives. Interviews were conducted with energy conservation professionals to identify and evaluate existing energy conservation programs, and interviews were conducted with consumers who had evaluated selected programs previously reviewed by the professionals. Information was also gathered on energy conservation activities of consumers surveyed. A directory of 34 energy conservation programs was also compiled. Some of the conclusions reached in this report are as follows. There is a need for an information system to gather data on existing conservation programs in order to increase the knowledge of relevant parties as to the outcomes of operating programs. This would help evaluation and improvement of current programs and suggest new program possibilities. The professionals rated six of the 34 programs highly, including the Energuide and the Canadian Home Insulation Program (CHIP). Retrofitting programs for houses are recommended for continuation and expansion, with some consideration given to linking these kinds of programs with home audit programs. In the private transport sector, any new conservation programs should be thoroughly tested on a small scale before widespread implementation, as evidence indicates that certain programs favorably evaluated by professionals may not be received favorably by consumers. 3 refs., 24 tabs.

Discretionary food fortification: implications of consumer attitudes.

Science.gov (United States)

Kalergis, Maria; MacDonald, Andrew

2009-01-01

The interest in, intent to, and impact of consuming foods fortified with vitamins and minerals, particularly foods of poor nutritional quality, were evaluated among Canadians. A Canada-wide, online survey of 1200 adults and teens was used to assess the interest in, intent to, and impact of consuming or serving foods fortified under two fortification scenarios (10% and 20% of the Recommended Daily Value). Categories of foods tested were cereal bars, energy bars, flavoured bottled water, frozen desserts, fruit drinks, fruit juice, salty snacks, soda pop, sports drinks, sweet baked goods, and sweets. The majority of adults and teens were interested in consuming fortified foods and indicated that they would increase their current consumption of specific foods if they became fortified. These foods included soft drinks, salty snacks, fruit drinks, and fruit juice. A large proportion of adults also indicated that they would serve more of these fortified foods to their children. Our findings reveal that fortifying foods, particularly those of poor nutritional quality, could lead to increased consumption of these foods among children, teens, and adults. Potentially, this could have a negative impact on eating habits and, in turn, could exacerbate the current nutrition-related health issues that Canadians face.

This study aims to identify consumer-level predictors of level of treatment response to illness management and recovery (IMR) to target the appropriate consumers and aid psychiatric rehabilitation settings in developing intervention adaptations. Secondary analyses from a multisite study of IMR were conducted. Self-report data from consumer participants of the parent study (n = 236) were analyzed for the current study. Consumers completed prepost surveys assessing illness management, coping, goal-related hope, social support, medication adherence, and working alliance. Correlations and multiple regression analyses were run to identify self-report variables that predicted level of treatment response to IMR. Analyses revealed that goal-related hope significantly predicted level of improved illness self-management, F(1, 164) = 10.93, p consumer-level predictors of level of treatment response have not been explored for IMR. Although 2 significant predictors were identified, study findings suggest more work is needed. Future research is needed to identify additional consumer-level factors predictive of IMR treatment response in order to identify who would benefit most from this treatment program.

2017-01-01

Despite extensive research investigating obesity, the problem continues to increase, particularly in poor, minority, and under-resourced communities. However, the literature continues to demonstrate many obesity-predicating variables are outside of personal volitional control, such as food-related consumer behaviors, which are strongly influenced by income and environment. This cross-sectional study (n = 5,109) employed secondary data analysis to quantitatively examine the effect of food-related consumer variables on obesity while controlling for covariates. Participants answered questions regarding money spent on food, time preparing meals, number of meals eaten at home and away from home, and types of food products consumed (frozen/fast foods, sodas, salty snacks, etc.) In this study, 48.9% of respondents were either overweight or obese. No significant differences were noted between the contextual variables examined and BMI scores. However, given the sample's limitations illuminated in the study, further research regarding the relationship between obesity and poverty-influenced, food-related consumer behaviors is warranted.

This paper reports the effect of boiling and frying on the retention of folate in commonly consumed Fijian vegetables (drumstick leaves, taro leaves, bele leaves, amaranth leaves, fern/ota, okra and French bean). The folate content was determined by microbiological assay (Lactobacillus casei rhamnosus) and tri-enzyme (protease, α-amylase and chicken pancreas conjugase) extraction treatment. The folate loss varied among the vegetables from 10-64% on boiling while 1-36% on frying. The higher folate loss was observed during boiling. The folate content in the water derived after boiling different vegetables ranged from 11.9 ± 0.5 to 61.6 ± 2.5 μg/100mL. The folate loss on boiling was accounted for in the cooking water. The predominant way of folate loss on boiling was leaching rather than thermal degradation which makes boiling the better choice of cooking the studied vegetables for folate intake, provided the cooking water is consumed together with the vegetables.

Full Text Available The paper analyses the notion of consumer in the European Union law, and, in particular, the notion of consumer in insurance law. The author highligts the differences between the notion of consumer is in aquis communautaire and in insurance law, discussing whether the consumer can be defined in both field in the same way, concerning that insurance services differ a lot from other kind of services. Having regarded unequal position of contracting parties and information and technical disadvantages of a weaker party, author pleads for broad definition of consumer in insurance law. In Serbian law, the consumer is not defined in consistent way. That applies on Serbian insurance law as well. Therefore, the necessity of precise and broad definition of consumes is underlined, in order to delimit the circle of subject who are in need for protection. The author holds that the issue of determination of the circle of persons entitled to extended protection as consumers is of vital importance for further development of insurance market in Serbia.

Sensory characteristics play a key role in determining consumers' acceptance of functional foods. In this context, the aim of the present work was to apply a combination of sensory and consumer methodologies to the development of chocolate milk desserts enriched with resistant starch. Chocolate milk desserts containing modified waxy maize starch were formulated with six different concentrations of two types of resistant starch (which are part of insoluble dietary fiber). The desserts were evaluated by trained assessors using Quantitative Descriptive Analysis. Moreover, consumers scored their overall liking and willingness to purchase and answered an open-ended question. Resistant starch caused significant changes in the sensory characteristics of the desserts and a significant decrease in consumers' overall liking and willingness to purchase. Consumer data was analyzed applying survival analysis on overall liking scores, considering the risk on consumers liking and willing to purchase the functional products less than their regular counterparts. The proposed methodologies proved to be useful to develop functional foods taking into account consumers' perception, which could increase their success in the market.

Using a model developed from the research literature, the authors compared consumers' attitudinal and behavioral responses to direct-to-consumer prescription drug advertising (DCTA) and over-the-counter nonprescription drug advertising (OTCA) of drugs. Adults 18 years of age and older who had taken any prescription drugs in the past 6 months completed online survey questionnaires. Variables measured included demographics (age, gender, race, education, and income), health-related characteristics (health status, prescription and over-the-counter drug use, health consciousness, and involvement with prescription or over-the-counter drugs), perceived amount of attention and exposure to DTCA and OTCA, attitudinal outcomes (skepticism toward DTCA/OTCA and attitude toward DTCA/OTCA), and behavioral outcomes triggered by DTCA and OTCA. The findings indicate that exposure to drug advertising is one of the most significant predictors of attitudinal and behavioral outcomes. Some audience factors such as health status, involvement with drugs, health consciousness, drug use, income, and age also were differentially associated with consumer responses to drug advertising.

Supply Chain Coordination and Consumer Awareness for Pollution Reduction

Directory of Open Access Journals (Sweden)

Bowon Kim

2016-04-01

Full Text Available To understand the dynamics of the manufacturer’s effort to reduce pollution in a supply chain consisting of manufacturer, retailer, and consumers, we analyze four cases according to consumer awareness of the pollution’s harmful effect, i.e., environmentally aware versus ignorant, and supply chain coordination, i.e., competitive versus cooperative. Applying differential games, we derive managerial implications: the most significant is that the supply chain coordination strategy becomes irrelevant to reducing the pollution, if the consumers are not environmentally aware or sensitive enough. It highlights the critical role played by the consumer awareness in curbing the pollution in the supply chain. In addition, we find the transfer price and the potential market size are important factors to determine each case’s relative effectiveness. Under a regular condition, where the transfer price from the retailer to the manufacturer is sufficiently high, the consumer-aware and competitive case can generate a better outcome in reducing the pollution than those with ignorant consumers. However, the opposite might occur if the transfer price is excessively low, giving the manufacturer little motivation to make an effort to reduce the pollution. For the cooperative supply chain, it is the potential market size that determines whether the consumer-aware case is better than the consumer-ignorant. In fact, it turns out that there is a stronger result, i.e., the feasibility condition enforces that the market is always big enough to make the consumer-aware cooperative case better than the consumer-ignorant cases. We further discuss managerial as well as policy implications of these analysis outcomes.

True or False: Consumer Perception to Green Consumer Retail

Directory of Open Access Journals (Sweden)

Sergio Silva Braga Junior

2016-09-01

Full Text Available The aim of this study was to analyze the influence of greenwshing in consumer awareness for green consumption in retail. Under this approach was evaluated if the greenwashing confuses consumers about what is to be green consumption and if it relies on green consumption. For the verification of the objective proposed by this work, an exploratory survey was conducted quantitative, through a survey with a sample of 359 respondents of São Paulo/Brazil. As for the justification of the method used, the exploratory research, with a non-probabilistic convenience sampling and quantitative nature, are characterized by a field approach seeking situational characteristics presented by respondents to generate quantitative measures of the attributes observed by them. For data collection was used a specialized company and market research and thus were collected data from real consumers. As a result it was observed that the greenwashing confuses consumed and does not influence the confidence of the green product.

The study aimed to understand predictors of consumers' purchase intention towards processed meat based functional foods (i.e. enriched processed meat). A cross-sectional survey was conducted with 486 processed meat consumers in spring 2016. Results showed that processed meats were perceived differently in healthiness, with sausage-type products perceived less healthy than cured meat products. Consumers were in general more uncertain than positive about enriched processed meat but differences existed in terms of the attitudes and purchase intention. Following regression analysis, consumers' purchase intention towards enriched processed meat was primarily driven by their attitudes towards the product concept. Perceived healthiness of existing products and eating frequency of processed meat were also positively associated with the purchase intention. Other factors such as general food choice motives, socio-demographic characteristics, consumer health and the consumption of functional foods and dietary supplements in general, were not significant predictors of the purchase intention for enriched processed meat.

Bulgogi (Korean traditional barbecued beef) is the most well-known Korean food to foreigners. There are, however, few studies on its sensory characteristics and consumer acceptability. This study was performed to identify the sensory attributes of Bulgogi samples prepared with different formulation and to compare the consumer acceptability in Korea and the United States. Bulgogi samples were prepared with varying levels of sugar and soy sauce with/without garlic or sesame oil. Descriptive analysis was conducted by 8 trained panelists. In consumer tests, 42 consumers in Seoul, Korea, 53 consumers in Davis (Calif., U.S.A.), and 39 consumers in St. Paul (Minn., U.S.A.) participated. Higher levels of sugar and soy sauce (SSS) significantly increased sweetness, saltiness, MSG taste, and soy sauce odor/flavor compared to the control made with the standard formula (CON). Elimination of sesame oil (ESO) significantly decreased sesame oil odor/flavor and oiliness, but increased green onion flavor. Elimination of garlic (EGC) significantly increased grilled beef odor/flavor, sesame oil odor/flavor, and oiliness, but decreased intensities of all the other attributes except bitterness. The consumers in Korea and the United States rated their overall liking for all samples similarly, preferring SSS to CON, EGC, and ESO. However Korean consumers seemed to detect the differences caused by formulation changes better than the U.S. consumers and these perceived differences seemed to impact the hedonic and the just-about-right ratings. Increase in soy sauce and sugar increased both Korean and the U.S. consumers' acceptability of Bulgogi, whereas eliminating garlic did not influence the consumer acceptability despite of its significant impact on sensory attributes. The food industry is increasingly interested in ethnic foods that satisfy sophisticated appetite of today's consumers. Korean cuisine is recently gaining popularity and perceived as "adventurous and spicy

Optimal Consumer Electronics Product Take-Back Time with Consideration of Consumer Value

Directory of Open Access Journals (Sweden)

Full Text Available Rapid economic growth in recent years has transformed our lifestyle to massively produce, consume, and dispose of products, especially for consumer electronics. This change has put great threat to our environment and caused natural resource depletion. Moreover, short product life cycles and quick replacements of consumer electronics create enormous electronic wastes (e-wastes. Without proper waste management, immense environmental damage is expected. In this empirical study, we notice that lots of valuable materials that can still be recycled from these used consumer electronics are left unused at home instead of being recycled at the appropriate time, which causes a low collection rate and a decrease in residual value for the used products. Therefore, it is important for the government and the recyclers to handle them efficiently by increasing the used product take-back rate. Our study develops an assessment model for customer value based on the idea of value engineering and the perspective of product life cycle. We also explore the relationship between product value and the total cost of ownership with an evaluation of their time variation, considering different usage modes for various consumer groups and different recycling award schemes (fixed and variable recycling awards. Proper take-back management is likely to create a win-win situation both for consumers and environmental protection. This study regards the notebook computer as an example to determine the optimal time for recycling laptops based on usage patterns and provides consumers a reference for when to replace their used product. The results from our modeling firstly clearly indicate that consumers with higher frequency of usage have shorter take back times and higher maximum consumer value. Secondly, a variable recycling award scheme with higher maximum consumer value is more practical than a fixed recycling award scheme.

Water resources for urban water and food security: the case of megacity Hong Kong

Vanham, Davy; Gawlik, Bernd; Bidoglio, Giovanni

2017-04-01

The extent to which urban dwellers consume resources is key on the path to reaching global SDGs. One of these resources is water, which is consumed in a direct and indirect way by city inhabitants, to achieve water and food security within city borders. In this study, we quantify the water resources required to provide these two essential securities for megacity Hong Kong. During the last years, this city has made large investments to make its urban water supply system more water efficient and sustainable. As such, its municipal water abstraction - often defined as direct water use - has decreased from 355 litres per capita per day (l/cap/d) in 2005 to 326 l/cap/d in 2013. Due to its political history, Hong Kong is unique in the world in data availability on urban food consumption. It is therefore the ideal case study to show typical urban food consumption behaviour and its related indirect water use. The current average diet in Hong Kong is very different to the average Chinese diet. It is characterised by a high intake of water intensive products like animal products and sugar, leading to a food related indirect water use or water footprint (WFcons) of 4727 l/cap/d. According to recommendations from the Chinese Nutrition Society for a healthy diet, the intake of some product groups should be increased (vegetables and fruit) and of other product groups reduced (sugar, crop oils, meat and animal fats). This would result in a reduction of the WFcons of 40% to 2852 l/cap/d. Especially the reduced intake of meat (including offals) from currently 126 kg per capita per year (kg/cap/yr) to the recommended value 27 kg/cap/yr would result in a substantial WFcons reduction. Meat consumption in Hong Kong is extremely high. A pesco-vegetarian diet would result in a reduction of 49% (to 2398 l/cap/d) and a vegetarian diet in a 53% (to 2224 l/cap/d) reduction. Hong Kong citizens can thus save a lot of water by looking at their indirect water use, through a change in their diet

The impact of transaction trust on consumers' intentions to adopt m-commerce: a cross-cultural investigation.

Mobile commerce (M-commerce) has been acknowledged as one of the most representative transaction types driving e-commerce worldwide; however, the potential security threats that keep consumers from M-commerce still confound the M-commerce industry. This research attempts to explore two questions: What are the dimensions of transaction trust that may significantly affect consumers' intentions to adopt M-commerce, and what are the cultural dimensions that may significantly moderate the impact of transaction trust on consumers' intentions to adopt M-commerce? A research framework based on the BATE model and Hofstede's cultural dimensions was established to identify how transaction trust and cultural value affect consumers' intentions to adopt M-commerce. Results revealed that transaction trust significantly affects consumers' intentions to adopt M-commerce. However, while uncertainty avoidance moderates the impacts of business trust and security on consumers' intentions of M-commerce adoption, both individualism/collectivism and long-term/short-term orientation moderate the relationship between security trust and consumers' intentions of M-commerce adoption.

This study provides a more precise understanding of the main driving forces of anthropogenic water use across countries. The anthropogenic water use was distinguished as blue water (i.e., fresh surface and groundwater) and total water (i.e. blue + green water; green water is rainwater insofar as it does not become runoff) used for producing, consuming, exporting, and importing of primary and manufactured goods and services, measured on a per country and per capita basis. The population effect on national blue water consumption associated with producing and consuming was found to be bigger than what the commonly assumed unitary population elasticity indicates. Distinct from the homogeneous affluence-water relationships conventionally assumed, this study revealed varying and potentially opposite effects affluence can have depending on the water use account of interest (e.g., production-based or consumption-based, blue or green) and the income level. Affluence, not the availability of freshwater resources, was found to be the most critical driver of virtual water imports. And a more affluent lifestyle in high-income countries was still associated with greater blue water consumption. With each doubling of income, blue water embedded in the goods and services a nation consumed and imported on a per capita basis increased by 82% and 86%, respectively, across the 110 countries analyzed for 2007. In comparison to affluence, the varying per capita water consumption accounts across the nations were much less sensitive to food consumption patterns. Given its critical role for water, land, and energy use shown by this and previous studies, affluence should be taken as a critical factor in future studies to better understand and leverage the water-energy-food-land nexus.
