    In India, most instruction in ecology and environment in schools and colleges comes from textbooks. Yet, this form of education rarely results in action. Children need to go into nature to study the flora, fauna, and ecosystems and into the environment to observe environmental problems, e.g., pollution, deforestation, and conservation processes. Educators need to first stir love and curiosity for nature so children can become aware of the environment and motivated to take action to preserve it. Well-conceived interpretive facilities with basic environmental information are needed in natural areas to help people identify plants and animals and learn about their characteristics and their interrelationships. They must incite joy and curiosity in what people can see rather than in what they cannot see. For example, many people go to national parks and sanctuaries to see a tiger or a leopard, but rarely see them. Nature study project material for children helps stir excitement about nature and their responsibility to respect it. Various groups have produced Joy of Learning, a handbook for environmental education activities. Environmental education depends on how educators can relate personal matters (e.g., wasteful use of paper to deforestation) to the environment. The National Museum of Natural History is committed to environmental education and to raising public awareness of conservation. It loans exhibits to classrooms. The Museum has a month-long summer program for teenagers called Exploring the Environment consisting of museum studies, nature field trips, urban field trips, and ecosystem observations in a national park or sanctuary. Its month-long program for younger children involves nature painting and animal modeling. The Touch, Feel, and Learn program benefits handicapped children. The Museum hosts 2-3 teacher workshops a year to orient them to museum resource materials and how to develop teaching aids. Other programs are outreach programs for children, college

    Young farmers in Europe, especially the beneficiaries of Common Agricultural Policy (CAP) funding schemes, are considered as the ones who could ensure the sustainability of the European Model of Agriculture. Economic efficiency and competitiveness, aversion of depopulation of rural areas and environmental protection constitute some of the key objectives of the CAP and young farmers are expected to play a role to all of them. This study proposes a way of measuring the potential of young farmers to contribute to the latter objectives of the CAP by estimating their environmental attitudes. Data from a questionnaire survey of 492 Greek young farmers were used to design a latent construct measuring their environmental attitudes. The latent construct was designed by means of an Explanatory Factor Analysis (EFA) using the responses to a set of 12 Likert-scale items. The results the EFA yielded a latent construct with three factors related to "Environmental pollution and policies (EPP)", "Environmental factors and food quality (EFF)" and "Farming practices and the environment". These results were validated through a CFA where 8 items in total were categorized in the three factors (latent variables). The utilization of the latent construct for the effective implementation of CAP measures could ameliorate the relationships of agriculture and environment in general.

    2015-11-01

    Given the potential of Perceived Consumer Effectiveness (PCE) in shaping pro-environmental behavior, the relationships between PCE, awareness of causes of contaminants in the marine environment, and concern about marine environmental contamination were investigated using Structural Equation Modeling (SEM). PCE is the belief that an individual has in being able to make a difference when acting alone. A web-based survey was performed in one western European country (Belgium), one northern European country (Ireland) and three southern European countries (Italy, Portugal and Spain), resulting in a total sample size of 2824 participants. The analyses confirm that European citizens are concerned about marine environmental problems. Participants from the southern countries reported the highest concern. In addition, the study participants did not have a strong belief in themselves in being capable of making a difference in tackling marine environmental problems. However, a higher awareness, which was associated with a higher degree of concern, enhanced the belief that an individual can make a difference in tackling marine environmental problems, though only when a concrete action was proposed. Consequently, information campaigns focusing on pro-environmental behavior are recommended to raise public awareness about marine environmental problems and at the same time explicitly refer to concrete possible actions. The findings indicate that when only awareness and concern are raised without mentioning a concrete action, PCE might even decrease and render the communication effort ineffective.

    Our environment is under constant pressure and threat from various sources of pollution. Science students, in particular chemistry students, must not only be made aware of these issues, but also be taught that chemistry (and science) can provide solutions to such real-life issues. To this end, a newly developed biochemistry laboratory experiment is described that guides students to learn about the applicability of peroxidase enzymes to degrade organic dyes (as model pollutants) in simulated waste water. In addition to showing how enzymes can potentially be used for waste water remediation, various factors than can affect enzyme-based reactions such as pH, temperature, concentration of substrates/enzymes, and denaturants can also be tested. This "applied biotechnology" experiment was successfully implemented in an undergraduate biochemistry laboratory course to enhance students' learning of environmental issues as well important biochemistry concepts. Student survey confirmed that this laboratory experiment was successful in achieving the objectives of raising environmental awareness in students and illustrating the usefulness of chemistry in solving real-life problems. This experiment can be easily adopted in an introductory biochemistry laboratory course and taught as an inquiry-guided exercise. © 2013 by The International Union of Biochemistry and Molecular Biology.

    2016-06-01

    There is a growing interest in the use of patient-reported outcomes to provide a more patient-centered view on treatment. Forgetting the artificial joint can be regarded as the goal in joint arthroplasty. The goals of the study were to describe changes in joint awareness in the artificial joint after total knee arthroplasty (TKA), and to determine which factors among pain, knee range of motion (ROM), quadriceps strength, and functional ability affect joint awareness after TKA. Patients undergoing TKA demonstrate changes in joint awareness and joint awareness is associated with pain, knee ROM, quadriceps strength, and functional ability. This prospective cohort study comprised 63 individuals undergoing TKA, evaluated at 1, 6, and 12 months postoperatively. Outcomes included joint awareness assessed using the Forgotten Joint Score (FJS), pain score, knee ROM, quadriceps strength, and functional ability. Fifty-eight individuals completed all postoperative assessments. All measures except for knee extension ROM improved from 1 to 6 months. However, there were no differences in any measures from 6 to 12 months. FJS was affected most greatly by pain at 1 month and by quadriceps strength at 6 and 12 months. Patients following TKA demonstrate improvements in joint awareness and function within 6 months after surgery, but reach a plateau from 6 to 12 months. Quadriceps strength could contribute to this plateau of joint awareness. Prospective cohort study, IV. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    2014-01-01

    The significance of public awareness (PA) programme at Kudankulam Nuclear Power Project (KKNPP) was well recognised since the inception stage itself and several PA programme were organised around Kudankulam through different means of communication. In its chequered progress, the Kudankulam project has seen ups and downs from the initial stage and in the year 2011, the site witnessed an impasse due to public interest and concerns on nuclear projects. Subsequently PA programmes were taken up on a war footing with persistent efforts, public fear on nuclear energy and safety concerns were allayed among local public in the villages in and around Kudankulam and also far and wide in Tamil Nadu and Kerala. This paper discusses the various measures initiated to disseminate the right information and educating public on nuclear energy as a clean energy option for environmental safety. In addition, it is a requirement of the country in the face of impending climate change concerns and warming of the earth's surface

    2017-01-01

    The Integrated Display and Environmental Awareness System (IDEAS) is an interdisciplinary team project focusing on the development of a wearable computer and Head Mounted Display (HMD) based on Commercial-Off-The-Shelf (COTS) components for the specific application and needs of NASA technicians, engineers and astronauts. Wearable computers are on the verge of utilization trials in daily life as well as industrial environments. The first civil and COTS wearable head mounted display systems were introduced just a few years ago and they probed not only technology readiness in terms of performance, endurance, miniaturization, operability and usefulness but also maturity of practice in perspective of a socio-technical context. Although the main technical hurdles such as mass and power were addressed as improvements on the technical side, the usefulness, practicality and social acceptance were often noted on the side of a broad variety of humans' operations. In other words, although the technology made a giant leap, its use and efficiency still looks for the sweet spot. The first IDEAS project started in January 2015 and was concluded in January 2017. The project identified current COTS systems' capability at minimum cost and maximum applicability and brought about important strategic concepts that will serve further IDEAS-like system development.

  15. Social Justice and Environmental Awareness Developed through a Citizens' Jury

    Science.gov (United States)

    Knight, J.

    2014-12-01

    A Citizens' Jury (CJ) is a discussion forum in which managers, policymakers or politicians are able to present their case to the general public ('citizens') to whom they are accountable, and for these citizens to critically ask questions of the managers/policymakers/politicians in order to better understand issues surrounding local development, planning and policy, impacts and adaptive measures, and to highlight their concerns. A CJ can be useful with respect to developing social justice and environmental awareness issues because it can empower community action and present different viewpoints. A practical CJ exercise is used in a second-year undergraduate course entitled Climate Change and Society, at University of the Witwatersrand, Johannesburg, South Africa. The CJ is used to consider some of the impacts of management policies used for climate change and sustainable development adaption, based on a hypothetical scenario. This scenario is that a major energy company wants to build a dam with hydroelectric power station in a developing country. This will provide low-carbon renewable energy to the country, investment in electricity infrastructure, and the company is committed to help economic development in the country, including in jobs and education. However, building and flooding of the dam will involve displacing 10,000 people from rural communities, flooding agricultural areas and areas of high biodiversity, and archaeological sites. The exercise is based on students, in groups, assuming different 'identities' which may include a local business person, resident, politician, member of an NGO, tourist, engineer, farmer etc, from which viewpoint they must argue for/against the proposal and to question other peoples' viewpoints. This exercise is useful because it allows students to develop understandings of different viewpoints, evaluate risk and impacts on different communities, and highlights the complexity of real-world decision-making.

    Damir Milos

    2014-04-01

    Full Text Available This article is the result of a survey conducted on first year students of the Faculty of Mechanical Engineering and Naval Architecture in Zagreb. Heavy particles in the focus of this article are intrinsic and extrinsic motivation of students and their ecological awareness and practice. Accordingly, we wanted to examine which form of motivation was prevalent in students when choosing a career in engineering and the degree of environmental awareness and practice of those students. The results show that extrinsic elements of motivation were more important to students in terms of their future career. When it comes to environmental awareness and practices, results show a higher level of environmental awareness and practices among students. Conclusively, it can be noted that the dominance of extrinsic motivation for a career does not compromise the interest in environmental issues or environmental practices.

    Full Text Available Economic growth was long perceived as the key goal of economic development. But as the capitalist economies got richer and as negative consequences of the growth spurt became more obvious, the development paradigm began to change course towards sustainability, which encompasses economic, environmental and social dimensions. The purpose of the article is to link the value system in the society and the possibility of the society to embrace the sustainable development model. We first provide the theoretical framework, followed by an empirical analysis of Croatia. The stress is on the environmental component of sustainability. The article builds from the popular stream of economic theory, i.e. economic analysis of happiness, which claims that happiness results not solely from economic factors, but also personal and broader social elements. These can also include environmental variables. In economic analysis of happiness, the consumer is not a standard utility maximizing consumer, who directly links utility and consumption of goods. His happiness is largely determined also by environmental elements. The existence of such consumers is consequently a prerequisite for the establishment of the sustainable economy. Empirical results show that: (1 consumers in general are at the moment not well educated about ecological problems, but (2 those that are give a lot of attention to environmental aspects. It is also important to note that future sustainability depends primarily on the attitude of current young cohorts (15 to 24 years, which, unfortunately, are least environmentally conscious. The role of the government and public institutions in preparing broader educational campaigns can therefore be significant.

  6. Interrelationship between a brand’s environmental embeddedness, brand awareness and company performance

    2007-07-01

    Full Text Available The purpose of the research was to define and measure a brand’s environmental embeddedness that, unlike the constructs used in previous environmental research, measures to which extent brand identity is embedded in environmental values. The purpose was also to assess a correlation of this variable to brand awareness and company performance. This study is based on three overlapping theoretical backgrounds: brand management, corporate social responsibility and organizational culture. Secondary data as well as content analysis and survey-based primary data were used. The results indicate a correlation between the environmental embeddedness of brands and brand awareness, but no correlation of these two variables to company performance. Such results support the idea that companies should indeed invest in being environmentally friendly so as to increase their chances of being recognized, while also indicating that the companies that own strong brands cannot afford not to be environmentally conscious as that could hurt their corporate brand values.

    The purpose of this paper is to explore effective mechanisms towards environmental awareness enhancement of the Thai public company. The environmental awareness has been strongly mentioned in the international agenda such as Agenda 21 to achieve sustainable development and be implemented at the global communities in all sectors. Thailand’s environmental awareness has been set up as the national policy and continuously promoted in the business sectors. The selected study area is one of Thai industrial public companies mainly utilizing natural resources for its business. Data collection was conducted by using questionnaires with a stratified sampling method comprising of 28 managerial and 134 operational levels. Descriptive statistics were be used for data analysis presented in terms of percentage. The study found that the effective mechanisms towards environmental awareness enhancement include employees’ participation in environmental friendly field trip, environmental knowledge provided by the company, supply chain involvement, law enforcement, and international environmental standard applied by the company. This study would recommend that public participation should be involved in order to make the mechanisms effectively.

  8. Dispatching strategies for coordinating environmental awareness and risk perception in wind power integrated system

    Wind power plays a significant role in economic and environmental operation of electric power system. Meanwhile, the variability and uncertainty characteristics of wind power generation bring technical and economical challenges for power system operation. In order to harmonize the relationship between environmental protection and risk management in power dispatching, this paper presents a stochastic dynamic economic emission dispatch model combining risk perception with environmental awareness of decision-makers by following the principle of chance-constrained programming. In this power dispatching model, the description of wind power uncertainty is derived from the probability statistic character of wind speed. Constraints-handling techniques as a heuristic strategy are embedded into non-dominated sorting genetic algorithm-II. In addition, more information is digested from the Pareto optimum solution set by cluster analysis and fuzzy set theory. The simulation results eventually demonstrate that the increase of the share of wind power output will bring higher risk, though it is beneficial for economic cost and environmental protection. Since different risk perception and environmental awareness can possibly lead to diverse non-dominated solutions, decision-makers may choose an appropriate dispatching strategy according to their specific risk perception and environmental awareness. - Highlights: • A dispatch model combining environmental awareness and risk perception is proposed. • The uncertain characteristic of available wind power is determined. • Constraints-handling techniques are embedded into genetic algorithm. • An appropriate decision-making method is designed. • Dispatching strategies can be coordinated by the proposed model and method.

    Increased public awareness of nuclear power runs the gamut from immediate disengagement to whole-hearted approval of the use of and expansion of this energy source. The involved study carried out at different Environmental Survey Laboratories (ESL) is mainly responsible for the environment friendly attitudes of the large section of public. The scientists working in these laboratories collected vast data on different environmental issues related to releases of very low levels of radioactivity in the environment. The total dose received by a hypothetical individual member of public (critical group) evaluated at plant boundary i.e. 1.6 km zone is generally in the range of 2-50 mSv/y which is about two order of magnitude less compared to limits prescribed by the Atomic Energy Regulatory Board (AERB) and International Commission on Radiological Protection ICRP) suggested value of 1 mSv/y. The ESL staff give special attention to communicate to the public to clear their queries and dislodge, their misconception about the nuclear facilities operating at their site. At ESL, various environmental pathways responsible for radiation dose and their impact on different environmental matrices are nicely presented in the form of charts and posters. Site and off-site emergency exercise are conducted regularly in co-ordination with inter governmental agencies responsible for mass sheltering, medical facilities and transportation. During these exercises mass communication programme are conducted to educate the public in the vicinity of Nuclear Power Plants Sites. ESL also updates from time to time the population distribution data within 30 km radial zone and the dietary habit of the population within this zone. (author)

    Full Text Available Objective: There is no treatment for asbestos–related diseases, but they can be prevented. One of the first interventions is to improve the knowledge level of people in order to protect people from asbestos and asbestos–related diseases. The present study was conducted to develop a questionnaire for measuring the knowledge and awareness level of asbestos and also assess its validity and reliability in a rural population that is exposed to asbestos environmentally. Methods: A questionnaire, interviewer–administered, that included 37 items was employed on a convenient sample consisting of adult persons who attended a tertiary teaching hospital in Eskişehir where asbestos exposure is widespread in its rural areas. After assessment of validity and reliability of the results, the questionnaire was refined to 19 items and one subscale. Results: A total of 760 participants were included in this study. The mean age of participants was 53.2±15.1 years and 51.6% of them were male. The discrimination and difficulty indices of the asbestos knowledge and awareness questionnaire ranged between 20.0–60.5% and 0.39–0.98, respectively. Cronbach’s alpha coefficient was 0.951 for overall items. The median (min–max and mean (SD score of the study population were 30 (19–56 and 33.9 (11.9, respectively. The score increased correspondingly with greater knowledge levels. Conclusion: This questionnaire is a practical and easy tool to apply with acceptable reliability and validity on high-risk adults in rural areas with environmental asbestos exposure.

    Livestock farming incurs large and varied environmental burdens, dominated by beef. Replacing beef with resource efficient alternatives is thus potentially beneficial, but may conflict with nutritional considerations. Here we show that protein-equivalent plant based alternatives to the beef portion of the mean American diet are readily devisible, and offer mostly improved nutritional profile considering the full lipid profile, key vitamins, minerals, and micronutrients. We then show that replacement diets require on average only 10% of land, 4% of greenhouse gas (GHG) emissions, and 6% of reactive nitrogen (Nr) compared to what the replaced beef diet requires. Applied to 320 million Americans, the beef-to-plant shift can save 91 million cropland acres (and 770 million rangeland acres), 278 million metric ton CO2e, and 3.7 million metric ton Nr annually. These nationwide savings are 27%, 4%, and 32% of the respective national environmental burdens.

    Full Text Available Environmental awareness and changing attitudes toward “green consumption” are becoming evident in emerging countries’ markets. Using an extended theory of planned behavior, this paper aims to examine emerging countries’ business students’ intentions to purchase green vehicles. Stratified random sampling was used to select study participants, and data were collected through face-to-face interviews. Results revealed that environmental knowledge and awareness have a significant influence on business students’ favorable attitudes toward green vehicles. Further, a significant association between attitudes toward green vehicles, perceived behavioral controls, and intentions to purchase green vehicles was observed. Findings serve to inform managers and policy makers who are formulating strategies for maximizing value creation in an era of increasingly environmentally aware consumers in emerging markets. Ultimately, this policy will help to promote green technology initiatives, and encourage higher rates of adoption of eco-friendly vehicles in emerging countries.

    Full Text Available Even though surf tourism in Portugal is an economic activity with a steady growth rate, there are not many assessment studies available. Using a survey undertaken in surf camps located in the Vila do Bispo County, this study aims to analyse the environmental awareness of surf tourists in the Algarve. Through the New Environmental Paradigm (NEP scale it is shown that the environmental attitudes of respondents are strongly pro-ecological but also reveal some anthropocentric aspects. Tourists were asked about their willingness to pay for an accommodation tax earmarked for environmental protection in the Algarve. The results show that the large majority (86% would be willing to pay, which indicates a high environmental awareness. It is also found that the willingness to pay is related to the nationality, with respondents from Germany, Austria and Switzerland showing a higher willingness to pay.

    To describe the sensitivity and specificity of Coma Recovery Scale-Revised (CRS-R) total scores in detecting conscious awareness. Data were retrospectively extracted from the medical records of patients enrolled in a specialized disorders of consciousness (DOC) program. Sensitivity and specificity analyses were completed using CRS-R-derived diagnoses of minimally conscious state (MCS) or emerged from minimally conscious state (EMCS) as the reference standard for conscious awareness and the total CRS-R score as the test criterion. A receiver operating characteristic curve was constructed to demonstrate the optimal CRS-R total cutoff score for maximizing sensitivity and specificity. Specialized DOC program. Patients enrolled in the DOC program (N=252, 157 men; mean age, 49y; mean time from injury, 48d; traumatic etiology, n=127; nontraumatic etiology, n=125; diagnosis of coma or vegetative state, n=70; diagnosis of MCS or EMCS, n=182). Not applicable. Sensitivity and specificity of CRS-R total scores in detecting conscious awareness. A CRS-R total score of 10 or higher yielded a sensitivity of .78 for correct identification of patients in MCS or EMCS, and a specificity of 1.00 for correct identification of patients who did not meet criteria for either of these diagnoses (ie, were diagnosed with vegetative state or coma). The area under the curve in the receiver operating characteristic curve analysis is .98. A total CRS-R score of 10 or higher provides strong evidence of conscious awareness but resulted in a false-negative diagnostic error in 22% of patients who demonstrated conscious awareness based on CRS-R diagnostic criteria. A cutoff score of 8 provides the best balance between sensitivity and specificity, accurately classifying 93% of cases. The optimal total score cutoff will vary depending on the user's objective.

    Current science education reforms and policy documents highlight the importance of environmental awareness and perceived need for activism. As "environmental problems are socially constructed in terms of their conceptualized effects on individuals, groups, other living things and systems research based on constructivist principles provides not only a coherent framework in which to theorize about learning, but also a context for understanding socially constructed issues" (Palmer and Suggate in Res Pap Educ 19(2), 2004, p. 208). This research study investigated the impacts of the learning processes structured based on the theories of constructionism and social constructivism on students' environmental awareness and perceived need for activism. Students constructed multimedia artifacts expressing their knowledge, attitudes, awareness, and activism about environmental issues through a constructionist design process. In addition, a social networking site was designed and used to promote social interaction among students. Twenty-two high school environmental science students participated in this study. A convergent mixed methods design was implemented to allow for the triangulation of methods by directly comparing and contrasting quantitative results with qualitative findings for corroboration and validation purposes. Using a mixed method approach, quantitative findings are supported with qualitative data (student video projects, writing prompts, blog entries, video projects of the students, observational field notes, and reflective journals) including spontaneous responses in both synchronous and asynchronous conversations on the social network to provide a better understanding of the change in students' environmental awareness and perceived need for activism. The findings of the study indicated that students' environmental awareness and perceived need for activism were improved at different scales (personal, community, global) throughout the constructionist and social

    2018-04-01

    Full Text Available The aim of this study was to investigate guest profiles at a hotel that has created a best-practices water management model to determine how different types of guests contribute to saving water during their stay. To do this, we analyzed levels of environmental awareness and pro-environmental behavior among the guests. Information was gathered through 648 structured surveys with guests at Hotel Samba in the Spanish seaside resort of Lloret de Mar between September 2015 and August 2016. Cluster analysis revealed four profiles of guests with different sociodemographic characteristics and different levels of awareness and proactivity in relation to water conservation. We combined our findings to develop a framework that illustrates how the two dimensions of environmental awareness and pro-environmental behavior are related in this setting. This article provides new insights into how hotel guests’ environmental awareness and engagement can influence a hotel’s water-saving efforts. These insights should help hotel operators to devise new, guest-centered strategies for saving water.

    In an effort to garner consensus around environmental programs, practitioners have attempted to increase awareness about environmental threats and demonstrate the need for action. Nonetheless, how beliefs about the scope and severity of different types of environmental concerns shape support for management interventions are less clear. Using data from a telephone survey of residents of the Puget Sound region of Washington, we investigate how perceptions of the severity of different coastal environmental problems, along with other social factors, affect attitudes about policy options. We find that self-assessed environmental understanding and views about the seriousness of pollution, habitat loss, and salmon declines are only weakly related. Among survey respondents, women, young people, and those who believe pollution threatens Puget Sound are more likely to support policy measures such as increased enforcement and spending on restoration. Conversely, self-identified Republicans and individuals who view current regulations as ineffective tend to oppose governmental actions aimed at protecting and restoring Puget Sound. Support for one policy measure—tax credits for environmentally-friendly business practices—is not significantly affected by political party affiliation. These findings demonstrate that environmental awareness can influence public support for environmental policy tools. However, the nature of particular management interventions and other social forces can have important mitigating effects and need to be considered by practitioners attempting to develop environment-related social indicators and generate consensus around the need for action to address environmental problems.

    To examine purchase patterns at fast-food restaurants and their relation to restaurant characteristics, customer characteristics, and use of calorie information. Cross-sectional survey. Fast-food restaurants in New York State. Adult fast-food restaurant customers (n = 1,094). Restaurant characteristics (fast-food chain type, presence of calorie labels, and poverty of location), participant characteristics (demographics, calorie knowledge, awareness, and use), and customer purchasing patterns (ordering low-calorie or no beverage, small or no fries, or restaurant and customer characteristics, fast-food chain customer age, sex, calorie use, and calorie awareness were independently associated with total calories purchased (all P < .05; model R2 = .19). When 3 purchasing patterns were added to the model, calorie use (P = .005), but not calorie awareness, remained associated with total calories purchased. The 3 purchase patterns collectively accounted for the majority of variance in calorie totals (Δ model R2 = .40). Promoting use of calorie information, purchase strategies, and calorie awareness represents complementary ways to support lower-calorie choices at fast-food chains.

    Full Text Available This study aims to give an insight about environmental awareness from public accountant and the role of Indonesian accounting professional bodies in ensuring professional sustainability. A naturalistic method was  applied to get deep understanding about the perspectives of the boards of professional bodies as a representation from the condition of public accountants in general. Data collection methods used in this study were interviews and focus group discussion. The findings highlight a variety of perspectives on knowledge of environment, interest in environmental accounting and moral responsibility on environmental damage. This variation shows different levels of awareness and it is mainly caused by the lack of law enforcement and no mandatory standards on environmental issues. This condition will threat legitimacy of accounting profession and finally, be able to endangered professional accounting sustainability. Limitations are about the scope and sample,which provide insights of the boards of public accountant professional bodies on environmental accounting issues. Future studies should be done on other accounting fields such as environmental audit, environmental accounting and reporting and environmental costing.

    2017-06-08

    We focus on the impacts of technological spillovers and environmental awareness in a two-echelon supply chain with one-single supplier and one-single manufacturer to reduce carbon emission. In this supply chain, carbon abatement investment becomes one of key factors of cutting costs and improving profits, which is reducing production costs in the components and products-the investment from players in supply chain. On the basis of optimality theory, the centralized and decentralized models are respectively established to investigate the optimal decisions and profits. Further, setting the players' profits of the decentralized scenario as the disagreement points, we propose a bargaining-coordination contract through revenue-cost sharing to enhance the performance. Finally, by theoretical comparison and numerical analysis, the results show that: (i) The optimal profits of players and supply chain improve as technological spillovers and environmental awareness increase, and the profits of them in the bargaining-coordination contract are higher than that in the decentralized scenario; (ii) Technological spillovers between the players amplify the impact of "free-ride" behavior, in which the supplier always incentives the manufacturer to improve carbon emission intensity, but the cooperation will achieves and the profits will improve only when technological spillovers and environmental awareness are great; (iii) The contract can effectively achieve coordinated supply chain, and improve carbon abatement investment.

    Full Text Available In sustainable development which requires the balance between the economic, social and environmental objectives, it is of key importance that the public also participates in the broadest sense. For the comprehension of ecological and developmental decisions it is necessary to provide information and to raise the general environmental awareness. An individual or groups of people base their reactions to negative phenomena in the environment on their perception of it, which does not always correspond to the objective state but is modified by different factors, also by the access to information and by the participation of the public in taking the decisions.

    Full Text Available Of the pollution that leads to serious health and genetic consequences, as well as the reaction of the organism, and thus the problem of Banat becomes the priority before the inhabitants of Banat raises a dilemma: stay at the cost of survival or survive with the engagement of all forms of civil and seostkog opinion and initiatives in terms of raising environmental awareness and create control mechanisms that will actively engage in the environmental fate of Banat. This research I wanted to find out how much the inhabitants of Banat to meet specified environmental problems and environmental zagađenjem. At the same time I wanted to remark on how much pollution adversely affects all the living world. During the research, when collecting data, used the research survey instrument. Survey respondents is included in the table. Respondents are the inhabitants of Banat of different gender, age and academic qualifications. When examining used a questionnaire that contains ten questions and that the materials in the descriptive method. The results suggest that in the future, you should have the most attention paid to development and raising environmental awareness through education of permanent inhabitants of Banat programs on the protection of the environment.

    Environmental damage occurring on individual, institutional, and societal levels is one of the major problems in the world and results from mostly unconscious human behavior. This damage poses serious threats to human health and other habitats. The aim of this study is to determine the level of environmental awareness of hotel and restaurant employees in the Amasra District of Bartin, Turkey. For this purpose, a descriptive survey method is used to measure 16 items with a 5-point Likert scale. Data are obtained from 200 employees in the hotels and restaurants as of 2015. The reliability coefficient is found to be 0.74. This data reveals that only 43% of hotels and 72% of restaurants in Amasra have recycling bins. Males and Bachelor's degree holders have more environmental awareness. Enterprises established after 2011 follow popular journals related to environment more than those before 2011. As a result, it is essential to organize educational meetings and seminars related to environmental awareness for hotel and restaurant employees in order to improve the tourism industry's environmental impact. The results show that the legislation has resulted in general environmental awareness and that the organizations are willing to change their business processes and environmental strategies. Nevertheless, despite their actions, there is little awareness of the benefits that can result from cost reductions resulting from environmentally friendly practices. Those affected by their suppliers act to reduce waste but do not deploy formal environmental management systems or use environmental messages to market their goods or services.

    Total variation (TV) regularization, originally introduced by Rudin, Osher and Fatemi in the context of image denoising, has become widely used in the field of inverse problems. Two major directions of modifications of the original approach were proposed later on. The first concerns adaptive variants of TV regularization, the second focuses on higher-order TV models. In the present paper, we combine the ideas of both directions by proposing adaptive second-order TV models, including one anisotropic model. Experiments demonstrate that introducing adaptivity results in an improvement of the reconstruction error. © 2013 Springer-Verlag.

    Full Text Available Carbon emissions reduction in supply chain is an effective method to reduce the greenhouse effect. The paper investigates the impacts of carbon trading price and consumers’ environmental awareness on carbon emissions in supply chain under the cap-and-trade system. Firstly, it analyzes the centralized decision structure and obtains the requirements to coordinate carbon emissions reduction and order quantity in supply chain. Secondly, it proposes the supply chain coordination mechanism with revenue-sharing contract based on quantity discount policy, and the requirements that the contract parameters need to satisfy are also given. Thirdly, assuming the market demand is affected by consumer’s environmental awareness in addition form, the paper proposes the methods to determine the optimal order quantity and the optimal level of carbon emissions through model optimization. Finally, it investigates the impacts of carbon trading price on carbon emissions in supply chain. The results show that clean manufacturer’s optimal per-unit carbon emissions increase as the carbon trading price increases, while nongreen manufacturer’s optimal per-unit carbon emissions decrease as the carbon trading price increases. For the middle emissions manufacturer, the optimal per-unit carbon emissions depend on the relationship between the carbon trading price and the carbon reduction coefficient.

    In this research, relationship between people's awareness of environmental capabilities of saving energy, photovoltaic power generation (PV) and nuclear power generation was investigated using questionnaire method. The results showed that saving energy is conducted without reference to its environment preservation effect. However the older people tend to regard saving energy as contribution to environment preservation. The attitude toward usage of PV has a close relationship to awareness of energy environmental concerns. Acceptance of cost sharing for the introducing of wide-scale PV systems to society is related to environment protection image of PV and the attitude toward loss of social convenience lost as a result of saving energy activities. The older people become, the more priority people put on environment protection before the social convenience. There is little relationship between environmental capabilities of nuclear power generation, that never discharge CO 2 on generation, and awareness of energy environmental concerns. (author)

    Full Text Available Background. The aim of our study was to assess the level of awareness and knowledge on environmental and occupational risk of cancer and its prevention among Polish students. We were interested also in their sources of knowledge. Methods. Survey, using the questionnaire, was conducted among 1080 respondents, who are or probably will be in their future work, exposed to harmful agents, due to study profile. Results. Students rated their knowledge on environmental and occupational cancer agents and cancer prevention mostly as limited (over 77%. Participation in “Safety Work and Environment” courses did not differentiate their level of cancer risk awareness. 901 students (84% responded to question about specific substances, which may cause cancer. Almost 2% of students indicated none from 10 given agents as carcinogenic. About 34% of respondents pointed all given agents, 39% pointed on 8–9 of them, 5–7 agents 13.2% of surveyed and 9% of them indicated on 1–4 agents. Students were aware of carcinogenic features of radiation, asbestos, cigarettes smoking (93.2–93.8%, benzene, benzo[?]pirene and pesticides (79,2 –83,6%. Less of them declared carcinogenic features of PAHs (75.4%, heavy metals (73.9%, electromagnetic field (64.8% and infections (60.8%. Only 48% of respondents specified possible lowering of the cancer by risk intervention practices. Medical and engineering profile, as well as attendance in courses covering the issues of health safety at work or environment (SWE significantly decreased percentage of respondents who didn’t specified any procedure (but it was still high: 48–62%. Conclusion. Our results demonstrate that most students, only to some extent, are aware of the most well known cancer-causing substances occurrence. Their knowledge is mostly limited and they do not know prevention procedures and ways to lower or eliminate the risk. Therefore the modernization of educational programs and development of more efficient

    Full Text Available The role of automation in sustainable development is not in doubt. Computerization in particular has permeated every facet of human endeavour, enhancing the provision of information for decision-making that reduces cost of operation, promotes productivity and socioeconomic prosperity and cohesion. Hence, a new field called information and communication technology for development (ICT4D has emerged. Nonetheless, the need to ensure environmentally friendly computing has led to this research study with particular focus on green computing in Africa. This is against the backdrop that the continent is feared to suffer most from the vulnerability of climate change and the impact of environmental risk. Using Nigeria as a test case, this paper gauges the green computing awareness level of Africans via sample survey. It also attempts to institutionalize green computing maturity model with a view to optimizing the level of citizens awareness amid inherent uncertainties like low bandwidth, poor network and erratic power in an emerging African market. Consequently, we classified the problem as a stochastic optimization problem and applied metaheuristic search algorithm to determine the best sensitization strategy. Although there are alternative ways of promoting green computing education, the metaheuristic search we conducted indicated that an online real-time solution that not only drives but preserves timely conversations on electronic waste (e-waste management and energy saving techniques among the citizenry is cutting edge. The authors therefore reviewed literature, gathered requirements, modelled the proposed solution using Universal Modelling Language (UML and developed a prototype. The proposed solution is a web-based multi-tier e-Green computing system that educates computer users on innovative techniques of managing computers and accessories in an environmentally friendly way. We found out that such a real-time web-based interactive forum does not

    Manley, M T; Serekian, P

    1994-01-01

    There is a growing concern that osteolytic lesions, often adjacent to otherwise stable implants, are a recent phenomenon caused by some recent change in polyethylene, metal, or other aspect of the total hip construction. This study investigates the possibility that bearings and modular connections used in modern hip replacements are an unappreciated source of particulate debris. Measurements taken from contemporary femoral bearings show a significant mismatch in both surface finish and sphericity of mating metal and polyethylene components, with sphericity of inserts being much worse then sphericity of femoral heads. The tolerances for sphericity of polyethylene inserts were further changed by the placement of an insert into its metal shell. Hip simulator tests of assembled inserts and shells showed greater polyethylene weight loss for metal-backed shells than for inserts alone. Bending and torsional tests of metal/metal modular connections showed that dynamic loads can release large numbers of debris particles from taper junctions. Because osteolytic lesions clearly are associated with overload of tissue by debris particles, the design, manufacture, and tolerances of modular connections in total hip replacement all seem to require reevaluation.

    Background : One of the unfortunate side effects of the industrial revolution has been the constant assault of the environment with various forms of pollution. Lately, this issue has taken a more critical dimension as prospects of global climate change and irreversible ecosystem damage are becoming a reality. Purpose : College graduates (especially chemists), should therefore not only be aware of these issues but also be taught how chemistry can help reduce environmental pollution. Furthermore, the role and importance of chemistry in sustainable development and solving environmental problems needs to be highlighted. Programme/intervention description : To this effect, we have designed a simple undergraduate experiment that is based on the green chemistry approach of using photolytic oxidation to degrade a model organic pollutant. This approach used UV light and hydrogen peroxide to produce reactive hydroxyl radicals, which subsequently break down and degrade Acridine Orange (model pollutant). The dye degradation was monitored spectrophotometrically and the apparent rate of decolouration was found to be first order. Possible radical initiated mechanisms that may be involved in this remediation experiment have been used to explain the observed dye decolouration. Sample : To test the usefulness of this newly developed experiment, we incorporated it as a module into a second year 'Professional skills' chemistry course with an enrollment of six female students. Anonymous survey of the students after the completion of the module was very positive and indicated that objectives of the experiment were satisfactorily achieved. Results : We believe this experiment not only raises students' awareness about green chemistry and environmental issues, but also teaches them valuable experimental skills such as experimental design, data manipulation and basic kinetics. Survey of students who were taught this unit in a second year course was very positive and supported the usefulness

    The purpose of Recycling Mentors was to implement an intergenerational, service-learning program focused on promoting recycling and environmental awareness among students enrolled in Community Health (HEA 301) and Current Issues in Gerontology (GRN 440/540) and adults older than 60 years. Recycling Mentors was conducted in New Hanover County (NHC), North Carolina, where a moderate climate and coastal location attracts many tourists, retirees, and college students. A community like NHC is a good place to implement service-learning that educates both students and older adults about the benefits of recycling to individual health and the environment. During the Fall 2009 semester, undergraduate and graduate students completed institutional review board training and then conducted the program with older adults. The education component of Recycling Mentors included a pre/post survey, brochure, and scheduled visits. Overall, Recycling Mentors was positive service-learning experience with students identifying salient outcomes such as learning about recycling and the environment and working with older adults. In addition, teaching the education component of Recycling Mentors was good practice for students who will be the future health professionals. While service-learning and environmentally themed projects are common, a program that combines the 2 like Recycling Mentors is unique and has the potential to motivate individual change while positively impacting the local community and the environment.

    The growth of China's industry has been seriously depending on energy and environment. This paper attempts to apply the directional distance function and the Luenberger productivity index to measure the environmental efficiency, environmental total factor productivity, and its components at the level of subindustry in China over the period from 1999 to 2009 while considering energy consumption and emission of pollutants. This paper also empirically examines the determinants of efficiency and productivity change. The major findings are as follows. Firstly, the main sources of environmental inefficiency of China's industry are the inefficiency of gross industrial output value, the excessive energy consumption, and pollutant emissions. Secondly, the highest growth rate of environmental total factor productivity among the three industrial categories is manufacturing, followed by mining, and production and supply of electricity, gas, and water. Thirdly, foreign direct investment, capital-labor ratio, ownership structure, energy consumption structure, and environmental regulation have varying degrees of effects on the environmental efficiency and environmental total factor productivity.

    Are residents living in communities around the Nevada Test Site aware of environmental remediation activities and do outreach efforts contribute to awareness? Through a U.S. Department of Energy (DOE) grant, the University of Nevada, Las Vegas administered a mail questionnaire to 14,083 residents and received 1,721 responses. Approximately 90% of the respondents reported awareness of past nuclear tests at the Nevada Test Site; 63% reported awareness of low-level radioactive waste disposal at the site; and 41% are aware that the Yucca Mountain Project for high level waste disposal is part of the Office of Civilian Radioactive Waste Management and not part of the Office of Environmental Management. Using both logit and probit regression models, at a 1% level of significance, respondents who reported obtaining information from the Community Advisory Board for Nevada Test Site Programs are more likely to be knowledgeable about low-level radioactive waste disposal activities and are more likely to be knowledgeable that the missions of the Office of Environmental Management and Office of Civilian Radioactive Waste Management are different.

    This research is motivated by the difference of market hygiene condition, where the market hygiene level is influenced by the environment around the market. In general, markets located near densely populated housing tend to be overlooked, while markets near elite housing tend to be clean. This condition is also influenced by marketers' awareness of market hygiene. If the market is near the elite neighbourhood, the level of awareness of sellers on cleanliness will be high. If the market is located in a densely populated area, sellers generally do not pay attention to cleanliness. The purpose of this research is to know the sellers's awareness of environmental cleanliness of Market Bulak, Klender Market and Rawamangun Market. Respondents in this study are sellers and buyers who make transactions in these 3 markets. This type of research is descriptive analysis with the method of observation and interview to 10 sellers in each market. Seller hygiene awareness are poor.

    Rivers in urban areas have been associated with water quality problems because of the practice of discharging untreated domestic and industrial waste into the water bodies. However, to what extent the public can identify specific environmental problems and whether people are ready to cope with potential risks is to a great extent unknown. Public environmental awareness of factors underpinning the pollution of rivers and approaches for reducing it were studied in Rasht City of Guilan Province in northern Iran, with Zarjub and Goharrud rivers as a case study. Data were collected from residents on the banks of the studied rivers using a questionnaire. Industrial areas, hospitals, and poultry farms were perceived as the main factors deteriorating water pollution of Zarjub and Goharrud rivers in Guilan Province. The discharge of urban sewage into the rivers was the second most important polluting factor. Most residents on the banks of Zarjub and Goharrud rivers showed high interest in the conservation of the environment. Overall, 62.7% of the residents had moderate, 20% had high, and 4% had very high environmental awareness. Families and mass media (TV and radio) were perceived of being the most important sources of information of family members concerning environmental awareness. According to the residents, the main approach for alleviating the pollution of Zarjub and Goharrud rivers were creating green spaces, dredging the rivers, establishing a water purifying system, and establishing a waste incinerator with a separation system (based on municipal planning). The public in the study area appeared well prepared to cope with the risks of water pollution, but further improving environmental awareness of the community can be a first step for preventing environmental degradation. The positive attitudes of the residents towards environmental conservation, the use of proper information sources, and practical training in the context of extension services can be effective in

    Restoration of mires is an issue of environmental awareness. This part of the paper has been divided into two sections: (i) description of international scientific experiments, and (ii) description of Estonian practice to restore or reclaim old peat cuttings. The presentations of the International Symposium on Peatland Restoration and Reclamation held in US in July 1998, and the IPS Jubilee Conference in Finland in September 1998 review the most common international scientific directions and practical results concerning peatland restoration and reclamation. The recolonising of the Sphagnum species and decreasing of gas emissions in old peat cuttings are a popular scientific task in the peatland restoration of today. In Estonia the area of old peat cuttings is currently about 3,000 ha to probably increase by 18,000 ha (Ramst, 1997). This means that Estonia should have its own program for sustainable peatland management, restoration and reclamation included. As an example of sustainable nature management the Summary considers the development of the US Surface Mining Control and Reclamation Act of 1977. This part is illustrated with photos demonstrating this law in practice in the Pennsylvania Coal Mining Region in summer 1997. Although regional institutions have been given priority to using mineral resources, the State should also be responsible for the restoration and reclamation of a exhausted mining area. (author)

    Firas Mohammed Al Rawashdeh, Dr.

    2014-06-01

    Full Text Available This study aims to identify the role of the modern concept of total quality management (TQM and how it is applied by the middle management that links between senior management and clients in the most important service sector: banks. It also aims to identify the middle management's awareness and understanding of the concept and importance of applying total quality management in commercial banks operating in Jordan. In general, the study found that there is a high awareness and understanding of the concept of total quality management. Middle management is also fully aware of the meaning and importance of total quality, but the role of middle management in the application of total quality management in commercial banks was very low. There are obstacles hindering the application of Total Quality Management. Therefore, the study recommended that middle management should be given the opportunity to apply Total Quality Management, because the role of this management is executive and has an important role in this area. There should be therefore a training plan with a timetable for all levels of management in the bank, and the banks should provide effective communication channels to identify customers’ needs, and create distinguished human relations among the staff. The workers should also be involved in the formulation of the vision and message of the bank. The researcher also recommended that there should be specialized administrative units interested in total quality management.

  20. Children's perceptions of rainforest biodiversity: which animals have the lion's share of environmental awareness?

    Directory of Open Access Journals (Sweden)

    Jake L Snaddon

    Full Text Available Globally, natural ecosystems are being lost to agricultural land at an unprecedented rate. This land-use often results in significant reductions in abundance and diversity of the flora and fauna as well as alterations in their composition. Despite this, there is little public perception of which taxa are most important in terms of their total biomass, biodiversity or the ecosystem services they perform. Such awareness is important for conservation, as without appreciation of their value and conservation status, species are unlikely to receive adequate conservation protection. We investigated children's perceptions of rainforest biodiversity by asking primary-age children, visiting the University Museum of Zoology, Cambridge to draw their ideal rainforest. By recording the frequency at which children drew different climatic, structural, vegetative and faunal components of the rainforest, we were able to quantify children's understanding of a rainforest environment. We investigated children's perceptions of rainforest biodiversity by comparing the relative numbers of the taxa drawn with the actual contributions made by these taxa to total rainforest biomass and global biodiversity. We found that children have a sophisticated view of the rainforest, incorporating many habitat features and a diverse range of animals. However, some taxa were over-represented (particularly mammals, birds and reptiles and others under-represented (particularly insects and annelids relative to their contribution to total biomass and species richness. Scientists and naturalists must continue to emphasise the diversity and functional importance of lesser-known taxa through public communication and outdoor events to aid invertebrate conservation and to ensure that future generations are inspired to become naturalists themselves.

    Full Text Available This research applies a positive stereotype perspective to test the effect of individuals’ choices between pro-environmental versus pro-safety behavior, while considering the role of media exposure. We test our hypotheses in China, where both food-safety and environment are major issues and are widely covered by the media and government reports. Based on a quasi-experiments and survey questionnaires focused on attitudes towards disposable chopsticks, we find that individuals form cognitive perceptions in ways that either have stronger positive environmental or safety stereotypes. Based on these stereotypes, they either believe that reusable chopsticks are more environmentally friendly or that disposable chopsticks are safer, each impacting individuals’ choices differently. In addition, awareness of information related to the environment augments the link between environmental stereotypes and pro-environmental behavior, while having no influence on the effect of safety stereotypes on pro-safety behavior. On the other hand, while awareness of safety-related information accentuates the link between safety-related stereotypes and pro-safety behavior, it has no impact on the effect of environmental stereotypes on pro-environmental behavior.

    2014-03-01

    A common finding in behavioural economics is that people often procrastinate, i.e., keep postponing planned tasks or decisions that require effort to execute. The effect of procrastination on inter-temporal energy choice behaviours could be even more serious because energy is an abstract, invisible and intangible commodity. This paper uses a web survey to investigate how people's procrastination propensity and environmental awareness affect their heating-energy-saving behaviours. The results indicate that people who state that they have a higher tendency to procrastinate are significantly less likely to have engaged in most of the heating energy-saving activities, especially regarding larger purchases or investments in equipment and the insulation of doors and windows. I also found a positive relationship between environmental awareness and engaging in everyday energy-saving activities such as reducing the indoor temperature. The findings suggest that measures aimed at reducing procrastination are needed to realise energy-saving potential. It is important to find ways to either bring future benefits closer to the present or to magnify the costs of delayed action. For example, one can employ certain feedback systems and commitment devices to make current gains and future costs more visible or tangible. - Highlights: • Norwegian online survey on factors affecting households' heating energy saving activities. • Identify the effect of procrastination and environmental awareness in energy saving decision making. • People with a higher tendency to procrastinate are less likely to engage in energy saving activities. • Procrastination can limit the positive effect of environmental awareness on energy saving. • Innovative behavioural measures are suggested to bring people's “energy saving plans or decisions” to action.

    2012-01-01

    The growth of China's industry has been seriously depending on energy and environment. This paper attempts to apply the directional distance function and the Luenberger productivity index to measure the environmental efficiency, environmental total factor productivity, and its components at the level of subindustry in China over the period from 1999 to 2009 while considering energy consumption and emission of pollutants. This paper also empirically examines the determinants of efficiency and productivity change. The major findings are as follows. Firstly, the main sources of environmental inefficiency of China's industry are the inefficiency of gross industrial output value, the excessive energy consumption, and pollutant emissions. Secondly, the highest growth rate of environmental total factor productivity among the three industrial categories is manufacturing, followed by mining, and production and supply of electricity, gas, and water. Thirdly, foreign direct investment, capital-labor ratio, ownership structure, energy consumption structure, and environmental regulation have varying degrees of effects on the environmental efficiency and environmental total factor productivity.

    2017-02-15

    Fracking has become a hot topic in the media and public discourse not only because of its economic benefit but also its environmental impacts. Recently, scientists have investigated the environmental impacts of fracking, and most studies focus on its air and ground water pollution. A systematic research structure and an overall evaluation of fracking's impacts on the environment are needed, because fracking does not only influence ground water but most environmental elements including but not limited to air, water, soil, rock, vegetation, wildlife, human, and many other ecosystem components. From the standpoint of the total environment, this communication assesses the overall impacts of fracking on the environment and then designs a total environmental study paradigm that effectively examines the complicated relationship among the total environment. Fracking dramatically changes the anthroposphere, which in turn significantly impacts the atmosphere, hydrosphere, lithosphere, and biosphere through the significant input or output of water, air, liquid or solid waste disposals, and the complex chemical components in fracking fluids. The proposed total environment study paradigm of fracking can be applied to other significant human activities that have dramatic impacts on the environment, such as mountain top coal mining or oil sands for environmental studies.

    2016-11-01

    Full Text Available Henceforth, new generations of Wireless Sensor Networks (WSN have to be able to adapt their behavior to collect, from the study phenomenon, quality data for long periods of time. We have thus proposed a new formalization for the design and the implementation of context-aware systems relying on a WSN for the data collection. To illustrate this proposal, we also present an environmental use case: the study of flood events in a watershed. In this paper, we detail the simulation tool that we have developed in order to implement our model. We simulate several scenarios of context-aware systems to monitor a watershed. The data used for the simulation are the observation data of the French Orgeval watershed.

    In the public and scientific discussion about options concerning solutions to the environmental problem, the role played by environmental awareness is often an area of interest. Two essential questions are posed: - What influence do environment-related attitudes have on the everyday, environmentally relevant actions of individuals? - What influence does environmental awareness have on voting behaviour and on the acceptance of environment policy measures? In this book, both questions are empirically examined in detail using, as examples, the choice of means of transport and the acceptance of measures to control traffic [de

  14. Ubiquitous Geo-Sensing for Context-Aware Analysis: Exploring Relationships between Environmental and Human Dynamics

    Directory of Open Access Journals (Sweden)

    Euro Beinat

    2012-07-01

    Full Text Available Ubiquitous geo-sensing enables context-aware analyses of physical and social phenomena, i.e., analyzing one phenomenon in the context of another. Although such context-aware analysis can potentially enable a more holistic understanding of spatio-temporal processes, it is rarely documented in the scientific literature yet. In this paper we analyzed the collective human behavior in the context of the weather. We therefore explored the complex relationships between these two spatio-temporal phenomena to provide novel insights into the dynamics of urban systems. Aggregated mobile phone data, which served as a proxy for collective human behavior, was linked with the weather data from climate stations in the case study area, the city of Udine, Northern Italy. To identify and characterize potential patterns within the weather-human relationships, we developed a hybrid approach which integrates several spatio-temporal statistical analysis methods. Thereby we show that explanatory factor analysis, when applied to a number of meteorological variables, can be used to differentiate between normal and adverse weather conditions. Further, we measured the strength of the relationship between the ‘global’ adverse weather conditions and the spatially explicit effective variations in user-generated mobile network traffic for three distinct periods using the Maximal Information Coefficient (MIC. The analyses result in three spatially referenced maps of MICs which reveal interesting insights into collective human dynamics in the context of weather, but also initiate several new scientific challenges.

It means the involvement and participation of Pesantren community and the peoples around it as well as the institutions whose have aim related with the program try to realizegood environmental health for communities around it. Through empowerment approach which positioning Pesantren community, local people, and related institutionas a subject, the moral and religion values in Pesantren into moral value of environmental sensein form of value and knowledge that should be improved for the better environment health. Environmental development engagement could be done through two kinds of approaches. First is by project approach and the second is motivation approach or it could be both of them in integrated way. The second approach (motivation), although relatively spend longer time, it will effected more positive because the target will gradually change their attitude and behavior in persuasive manner. The behavior of ignoring environmental problem will turn into dynamically attitudes that will always grow and culminate in stability of environmental engagement

    There is a lack of studies assessing the exposure-response relationship between transportation noise and annoyance in North America. Our aims were to investigate the prevalence of noise annoyance induced by road traffic, trains and airplanes in relation to distance to transportation noise sources, and to total environmental noise levels in Montreal, Canada; annoyance was assessed as noise-induced disturbance. A telephone-based survey among 4336 persons aged >18 years was conducted. Exposure to total environmental noise (A-weighted outdoor noise levels-LAeq24h and day-evening-night equivalent noise levels-Lden) for each study participant was determined using a statistical noise model (land use regression-LUR) that is based on actual outdoor noise measurements. The proportion of the population annoyed by road traffic, airplane and train noise was 20.1%, 13.0% and 6.1%, respectively. As the distance to major roads, railways and the Montreal International Airport increased, the percentage of people disturbed and highly disturbed due to the corresponding traffic noise significantly decreased. When applying the statistical noise model we found a relationship between noise levels and disturbance from road traffic and total environmental noise, with Prevalence Proportion Ratios (PPR) for highly disturbed people of 1.10 (95% CI: 1.07-1.13) and 1.04 (1.02-1.06) per 1 dB(A) Lden, respectively. Our study provides the first comprehensive information on the relationship between transportation noise levels and disturbance in a Canadian city. LUR models are still in development and further studies on transportation noise induced annoyance are consequently needed, especially for sources other than road traffic.

    To compare the patients ability to forget the artificial knee joint in everyday life who were randomized to be operated for mobile- or fixed-bearing total knee arthroplasty (TKA). This single-center randomized controlled trial evaluated the 3-year follow-up of the cemented mobile- and fixed-bearing TKA from the same brand in a series of 41 patients. Clinical examination was during the pre-, 6-week, 6-month, 1-, 2- and 3-year follow-up containing multiple patient-reported outcome measures (PROMs) including the 12-item Forgotten Joint Score (FJS-12) at 3 years. Effect size was calculated for each PROM at 3-year follow-up to quantify the size of the difference between both bearings. At 3-year follow-up, general linear mixed model analysis showed that there were no significant or clinically relevant differences between the two groups for all outcome measures. Calculated effect sizes were small (awareness was slightly lower in patients operated with the MB TKA with comparable improved clinical outcome and PROMs at 3-year follow-up. Measuring joint awareness with the FJS-12 is useful and provides more stringent information at 3-year follow-up compared to other PROMs and should be the PROM of choice at each follow-up after TKA. Level I, randomized controlled trial.

    Full Text Available This research aims to study the environmental perception of a group of residents of two neighborhoods surrounding the Botanical Garden City Park in Sinop-MT, revealing their relationship with the area as well as their involvement in proposing alternatives for the conservation of the Park. With this aim a study on the Botanical Garden Municipal Park was carried out, using the following procedures: documentary research in public agencies; site visits for description of the area and semi-structured interviews with a group of residents of two neighborhoods in the vicinity, Celeste Garden and the Botanical Garden. The presence of fauna, flora and springs that form Ribeirão Nilza within the park indicates the need for its conservation, and the residents consider the area important for the local micro weather, tourism, biodiversity conservation and also to develop researches, contributing significantly to the population's quality of life. Taking into account the above considerations, it is important to consider a new scenario, which aims to mobilize social participation, propitiating the people the feeling of belonging to what they conceive as the environment, giving rise to a participatory management by means of Environmental Education.

Teaching the scientific method or learning cycle (theory, research, instrumentation, operations, data analysis, and presentation) is a significant pedagogical building block that stimulates and retains students and prepares them well for graduate school and professional careers. Students obtain a personal ownership of their education when they engage in state-of-the-art balloon launch capability into the "unknown" with real-time data (50 Kb) with command interaction. The scientific method comes alive with creativity, problem solving, fun, and multidisciplinary hands-on team work. More students in basic science (and liberal arts) and public have an awareness of the environment, atmosphere, space, and heavens by direct probing and remote sensing from "New Heights" (over 98% of atmosphere at 30 km altitude).

    The Real-time Observatories, Application, and Data management Network (ROADNet) Program aims to develop an integrated, seamless, and transparent environmental information network that will deliver geophysical, oceanographic, hydrological, ecological, and physical data to a variety of users in real-time. ROADNet is a multidisciplinary, multinational partnership of researchers, policymakers, natural resource managers, educators, and students who aim to use the data to advance our understanding and management of coastal, ocean, riparian, and terrestrial Earth systems in Southern California, Mexico, and well off shore. To date, project activity and funding have focused on the design and deployment of network linkages and on the exploratory development of the real-time data management system. We are currently adapting powerful "Data Grid" technologies to the unique challenges associated with the management and manipulation of real-time data. Current "Grid" projects deal with static data files, and significant technical innovation is required to address fundamental problems of real-time data processing, integration, and distribution. The technologies developed through this research will create a system that dynamically adapt downstream processing, cataloging, and data access interfaces when sensors are added or removed from the system; provide for real-time processing and monitoring of data streams--detecting events, and triggering computations, sensor and logger modifications, and other actions; integrate heterogeneous data from multiple (signal) domains; and provide for large-scale archival and querying of "consolidated" data. The software tools which must be developed do not exist, although limited prototype systems are available. This research has implications for the success of large-scale NSF initiatives in the Earth sciences (EarthScope), ocean sciences (OOI- Ocean Observatories Initiative), biological sciences (NEON - National Ecological Observatory Network) and

    Aircraft noise perception is related to several variables that are tangible and objective, such as the number of operations, flight schedules. Other variables, instead, are more subjective, such as preferences. However, although their elusiveness, they contribute to determine the individuals' perception of this type of externality. Despite the fact that the complaints related to aeronautical noise have been registered since the decade of 50, it has been observed that the perception of noise seems to have grown, especially since the 80's. It has been argued that this change in noise perception has its roots on the accelerated expansion of air traffic. But, it is necessary to point out the important role played on modeling preferences, by the growing environmental conscience and the higher welfare and quality of life standards and expectations. In that context, the main objective of this paper is to study the aeronautical noise perception in the neighborhoods of the Aeroporto Internacional de Sao Paulo - AISP (the biggest airport of South America). Specifically, it analyzes the relationship between aircraft noise perception and social class, which is expected to be positive. Since noise perception is an intangible variable, this study chose as a proxy the value losses of residential properties, caused by aeronautical noise. The variable social class has been measured utilizing average per capita income of the population who live nearby the airport. The comparison of both, the lowest and the highest social class suggests that the relationship between social class and noise perception is positive in the AISP region. Moreover, it was observed that all social classes are very susceptible to aircraft noise annoyance. In fact, the magnitude of the noise perception proxy for both social classes -the residential value losses- was found to be comparable to levels encountered in developed countries.

    Full Text Available The development of the belt and road region leads cities to significantly increase the amount of public expenditure on the new construction of facilities and infrastructure. Mass construction not only relies on many environmental resources, but might also destroy the local natural environment. In order to reveal the importance of the natural environment, this study explores the economic value of the natural landscape for sport tourism in Taiwan. While the concept of total economic value (TEV is applied to the Sun–Moon Lake Swimming Carnival Event, the travel cost method (TCM is adopted to estimate the use value for participants, and the double-bounded dichotomous contingent valuation method (CVM and survival analysis are performed to evaluate the non-use value for the residents. The use value is on average NT$ 5668 for one participant. The median willingness to pay for the option value, existence value and bequest value of every resident is NT$433, NT$411 and NT$274, respectively.

    Full Text Available Tourism is perceived as an economic, social and cultural phenomenon with important social and environmental impacts. In Brazil, the Rio de Janeiro is a city that receives the most foreign tourists. However its beaches face problems because of pollution. In this context, analysis of the socio environmental awareness of tourists and hotel managers on the quality of Rio's beaches constitutes a factor in the reflection of environmental impacts and, above all, for public policies aimed at tourism. Thus, the objective of this research was to analyze the environmental awareness of tourists and managers of hotels on the impacts of pollution on the beaches of Rio de Janeiro tourism. To do this, they applied semi-structured questionnaires for tourists and managers of hotels. The results showed that tourists arriving in the city are more concerned with enjoying the beauties and the sights than to learn about the environmental conditions of Rio de Janeiro. It could be observed also that the beaches strongly influence the image they have of the city. For this reason, although most of them realize the pollution of beaches, both for aesthetics, as the public health, does not compromise the interest in visiting the Rio de Janeiro nor in attending the beaches for swimming. It is noteworthy that even in hotels that develop strategies that help educate guests, they continue with just tourists perception and do not seek to find out about potential health risks.

    The environmental impact assessment system and the environmental plan for the preservation of the land environment are carried out with the aim of preventing damage to the environment caused by human activities, improving the quality of life and creating a pleasant environment. However, despite these various systems, the natural resources have been continuously damaged, and the system to cope with them has been advanced, but there has been a limit to fully conserve natural resources from development. The total amount of natural resources is being promoted as a part of the purpose of supplementing the system, but the evaluation method of the total amount of natural resources suitable for domestic situation is not presented yet. Natural resources are diverse and complicated in their categories and elements, and their measurement units are also diverse, making it difficult to synthesize them into one unit. Therefore, in this study, we proposed a method to calculate the total amount by using the evaluation map of the Environmental Conservation Value Assessment Map (ECVAM) which derives the final achievement with 5 grades using 65 evaluation items. However, we consistently applied the weight twice as much as the grade and did not utilize any information other than the map of ECVAM. The results of this study can be applied to the Total Natural Resources Management System through follow-up study such as application of various environmental information and weighting method.

    Geographic Information Systems (GIS) offer a plethora of applications for numerous fields, from geological sciences to urban planning. Therefore, developing a practical GIS curriculum for students from a diverse selection of majors can be challenging, especially since time constraints presented by the course term limit the number of projects that can cater to each student's academic focus. However, open ended assignments that allow students the freedom to personalize their projects present an opportunity to teach the universal functionality of GIS, as well as stimulate curiosity of students from all backgrounds by allowing them to tailor a project to their personal interests. During an introductory GIS course at the University of California, San Diego, projects prompted students to utilize ArcGIS in ways of their choice that raised awareness of local environmental issues, as well as encouraged students to incorporate environmentally sustainable practices into their lives. In view of the frequently stated interest of students to enter careers where they can use their newly learned GIS skills, the educational platform of choice is ESRI's ArcGIS, but the choice of platform remains flexible. As GIS resources become more accessible with the development of programs such as OpenGIS and OpenStreetMap, the potential for GIS to effectively communicate environmental issues to the public is growing fast. Incorporating these environmental issues into a curriculum not only allows students to personalize their education, but also raises awareness of such problems and provides students with the ability to communicate those issues using GIS.

    An expedited environmental management process has been developed at the Idaho National Engineering and Environmental Laboratory (INEEL). This process is one result of the Lockheed Martin commitment to the US Department of Energy to incorporate proven systems engineering practices with project management and program controls practices at the INEEL. Lockheed Martin uses a graded approach of its management, operations, and systems activities to tailor the level of control to the needs of the individual projects. The Lockheed Martin definition of systems engineering is: ''''Systems Engineering is a proven discipline that defines and manages program requirements, controls risk, ensures program efficiency, supports informed decision making, and verifies that products and services meet customer needs.'''' This paper discusses: the need for an expedited environmental management process; how the system was developed; what the system is; what the system does; and an overview of key components of the process

    Children nowadays, particularly in urban areas, are more disconnected from nature than ever before, leading to a large-scale “extinction of experience” with the natural world. Yet there are many potential benefits from children interacting with nature first-hand, including via outdoor learning opportunities. Urban environmental education programmes typically aim to increase awareness and knowledge of local biodiversity and to promote positive attitudes and behaviour towards the environment. However, limited research has been conducted evaluating to what extent these interventions achieve their goals. Here, we explore and assess the influence of a six-week bird-feeding and monitoring project conducted within school grounds (“Bird Buddies”) on individual awareness, knowledge and attitudes towards birds by primary school children. This initiative was conducted across eight (sub-)urban primary schools within Brighton and Hove (UK), with 220 participating children (aged 7 to 10). Via pre- and post-project questionnaires, we found evidence for enhanced awareness of local biodiversity, alongside significant gains in both bird identification knowledge and attitudes, which were greatest for children with little prior exposure to nature. Many children expressed a keenness to continue improving the environmental value of their school grounds and to apply elements of the project at home. Student project evaluation scores were consistently positive. Mirroring this, participating teachers endorsed the project as a positive learning experience for their students. One year after the project, several schools were continuing to feed and watch birds. Collectively, the findings from this study highlight the multiple benefits that can be derived from engagement with a relatively short outdoor environmental activity. We therefore believe that such interventions, if repeated locally/longer term, could enhance children’s experience with nature in urban settings with combined

  20. The Impact of Environmental Regulation on Total Factor Energy Efficiency: A Cross-Region Analysis in China

    2017-10-01

    Full Text Available Environmental regulations are the key measure by which governments achieve sustainable environmental and economic development. This study aimed to determine the direct and indirect impacts of environmental regulations on total factor energy efficiency of regions in China. Since regions have different levels of economic development and resource endowment, we used the slacks-based measure (SBM-undesirable model to calculate total factor energy efficiency considering regional technology heterogeneity and examined the regional impacts of environmental regulation on this efficiency using the Tobit regression model. A positive direct impact was generated in the eastern region of China by the forced mechanism, which forced enterprises to reduce fossil fuel energy demand and increase clean energy consumption; whereas a negative direct impact was generated in the middle and western regions owing to the green paradox, which is the observation that expected stringent environmental regulation prompts energy owners to accelerate resource extraction. Moreover, indirect impacts through technological progress and foreign direct investment were taken into account in the model, and the results show that the indirect impacts vary across regions. A logical response to these findings would be to develop different policies for different regions.

    We evaluated the relative impact of anthropogenic polycyclic aromatic hydrocarbons (PAHs) among biogeochemical variables on total, metabolically active, and PAH bacterial communities in summer and winter in surface microlayer (SML) and subsurface seawaters (SSW) across short transects along the NW Mediterranean coast from three harbors, one wastewater effluent, and one nearshore observatory reference site. At both seasons, significant correlations were found between dissolved total PAH concentrations and PAH-degrading bacteria that formed a gradient from the shore to nearshore waters. Accumulation of PAH degraders was particularly high in the SML, where PAHs accumulated. Harbors and wastewater outfalls influenced drastically and in a different way the total and active bacterial community structure, but they only impacted the communities from the nearshore zone (PAH concentrations on the spatial and temporal dynamic of total and active communities in this area, but this effect was putted in perspective by the importance of other biogeochemical variables.

    A general case of release to the atmosphere of a pollutant is considered. In hazards evaluation the processes involved are usually estimated conservatively so as to maximize the computed doses. The present work helps to identify the worst cases. In addition, a model of the total dose is presented and its variations are studied as a function of wind speed, deposition velocity and source height. The value of each parameter giving the highest total dose as a function of the model's parameters is determined. (H.K.)

    The aim of this study was to deepen the assessment of the environmental impacts of a white wine produced in Sardinia (FU 750 ml), performing an attributional LCA. The system boundaries were extended, from 'cradle to gate' (partial LCA) of a previous study, to 'cradle to grave' (total LCA), in order to identify the environmental impacts occurring along the wine life cycle stages (vine planting, grape production, wine production, bottling and packaging, distribution, final disposal of the glass bottle). Some assumptions were made in order to quantify the environmental impact of the transportation phase, regarding the few data which were available. Inventory data were mainly collected through direct communication with the Company involved in the study. Results showed that the environmental performance of wine was mostly determined by the glass bottle production (for all impact categories except ozone layer depletion). The second contributor was the agricultural phase, which included two sub-phases: vine planting and grape production. Results showed that the vine planting sub-phase was not negligible given its contribution to the agricultural phase, mainly due to diesel fuel consumption. Transportation impact was found to be relevant for long distance distribution (USA); the impact categories more affected by transport were acidification, eutrophication, photochemical oxidation and global warming potential. Suggested opportunities to reduce the overall environmental impact were the introduction of a lighter glass bottle or the substitution of the glass bottle with a polylaminate container.

    The studies presented in this thesis address the consequences of market distortions of governmental policies - predominantly in the area of environmental and energy policy. The studies cover different economic aggregation levels: The first study aims at investigating firm-level effects. Thus, the results refer only to a small number of well-defined economic entities, e.g. electricity supply companies in Germany. Subsequently, issues - such as the evaluation of efficiency effects of the European Emissions Trading system - are addressed on a multi-sectoral and multi-regional level, but still only one market is considered. Thereupon, the scope of investigation is broadened by interactions of different markets - e.g. as in the case of the economic evaluation of renewable energy promotion strategies. Finally, a general equilibrium analysis of a European nuclear phase-out scenario covers all economic feed-backs on the national and international level. (orig.) 5.

    The tritiated water dilution technique was used to determine the total body water (TBW) and water turnover rate (WTR), which is assumed to be similar to water intake, in water buffalo, Red Danish cattle, fat-tailed Osemi sheep and crossed Nubian-Bedouin goats and camels (Camelus dromedarius). There was a significant (P < 0.05) effect of species on TBW and WTR. The combined data of buffalo, cattle and sheep revealed a significant (P < 0.05) effect of pregnancy on TBW, but not on WTR. The combined data of buffalo and cattle showed a significantly lower TBW (P < 0.01) and a higher WTR (P < 0.05) in lactating animals than in heifers. In buffalo WTR was on average 81% higher in summer grazing (SG) than in spring. It was also 118 and 20% higher in summer non-grazing (SNG), than in either spring or SG, respectively. The differences between treatments in heifers, pregnant and lactating, were significant (P<0.01), except between spring and SG in heifers. The TBW was on average 12% higher in SG than in spring. It was also 18 and 5% higher in SNG than in either spring or SG, respectively. The differences between treatments in heifers, pregnant and lactating, were significant, except between SG and SNG in heifers and lactating cows and between spring and SG in lactating cows. (author)

  10. A total cost perspective on use of polymeric materials in solar collectors – Importance of environmental performance on suitability

    2014-01-01

    Highlights: • A polymeric solar collector system was compared with two traditional ones. • It was found the best in terms of climatic performance per solar heat collected. • The differences in climatic cost between the systems compared however are small. • The low climatic cost makes solar heating better compared to natural gas heating. • Use of Ecoindicator 99 for environmental cost makes solar heating even better. - Abstract: To assess the suitability of solar collector systems in which polymeric materials are used versus those in which more traditional materials are used, a case study was undertaken. In this case study a solar heating system with polymeric solar collectors was compared with two equivalent but more traditional solar heating systems: one with flat plate solar collectors and one with evacuated tube solar collectors. To make the comparison, a total cost accounting approach was adopted. The life cycle assessment (LCA) results clearly indicated that the polymeric solar collector system is the best as regards climatic and environmental performance when they are expressed in terms of the IPPC 100 a indicator and the Ecoindicator 99, H/A indicator, respectively. In terms of climatic and environmental costs per amount of solar heat collected, the differences between the three kinds of collector systems were small when compared with existing energy prices. With the present tax rates, it seems unlikely that the differences in environmental and climatic costs will have any significant influence on which system is the most favoured, from a total cost point of view. In the choice between a renewable heat source and a heat source based on the use of a fossil fuel, the conclusion was that for climatic performance to be an important economic factor, the tax or trade rate of carbon dioxide emissions must be increased significantly, given the initial EU carbon dioxide emission trade rate. The rate would need to be at least of the same order of magnitude

    1995-01-01

    At the Fernald Environmental Management Project (FEMP) in southwestern Ohio, ICP-mass spectrometry (ICP-MS), with sample introduction by peristaltic pumping, is used to determine total and isotopic uranium (U-234, U-235, U-236 and U-238) in soil samples. These analyses are conducted in support of the environmental cleanup of the FEMP site. Various aspects of the sample preparation and instrumental analysis will be discussed. Initial sample preparation consists of oven drying to determine moisture content, and grinding and rolling to homogenize the sample. This is followed by a nitric/hydrofluoric acid digestion to bring the uranium in the sample into solution. Bismuth is added to the sample prior to digestion to monitor for losses. The total uranium (U-238) content of this solution and the U 235 /U 238 ratio are measured on the first pass through the ICP-MS. To determine the concentration of the less abundant U 234 and U 236 isotopes, the digestate is further concentrated by using Eichrom TRU-Spec extraction columns before the second pass through the ICP-MS. Quality controls for both the sample preparation and instrumental protocols will also be discussed. Finally, an explanation of the calculations used to report the data in either weight percent or activity units will be given

    Full Text Available This work aims to analyze the treatment of environmental issues in an educational proposal for Intercomprehension in Romance Languages (hereinafter called IC developed by InterRom, a research team from Universidad Nacional de Córdoba, in Argentina. This proposal, aimed at developing high school seniors’ language skills from the perspective of teaching and learning IC from text genres, integrates pluralistic approaches to languages with contributions from socio-discursive interactionism (BRONCKART, 2007, from the sociocultural theory of human development (BRUNER, 1994; NELSON, 1996; ROGOFF, 1993; VYGOTSKY, 1962, 1988 and from cognitive approaches to text comprehension and production (BRITTON and GRAESSER, 1996; HAYES and FLOWERS, 1980, HAYES, 1996; SCARDAMALIA and BEREITER, 1992. Through the convergence of these theoretical perspectives, the proposal promotes IC in French, Italian, Spanish and Portuguese, related to environmental conservation, as well as actions for writing texts in Spanish. The planned language activities involve working with different text genres on environmental issues, such as the extinction of animal species, the production of genetically modified foods and the use of agrochemicals that contaminate the biosphere and threaten the life of all living species, including human beings. The exercises related to these topics, at the same time, encourage students to reflect on critical environmental issues and to develop strategies for writing texts in Spanish. To conclude, it can be argued that the IC proposal is based on social and intercultural approaches that integrate teaching actions, text production processes and science issues regarding the environment. As a result, students are regarded as subjects with competencies to understand discourses from different cultures and to think, write and act within their natural, social and cultural environments.

  13. Designing a Situational Awareness Information Display: Adopting an Affordance-Based Framework to Amplify User Experience in Environmental Interaction Design

    Full Text Available User experience remains a crucial consideration when assessing the successfulness of information visualization systems. The theory of affordances provides a robust framework for user experience design. In this article, we demonstrate a design case that employs an affordance-based framework and evaluate the information visualization display design. SolarWheels is an interactive information visualization designed for large display walls in computer network control rooms to help cybersecurity analysts become aware of network status and emerging issues. Given the critical nature of this context, the status and performance of a computer network must be precisely monitored and remedied in real time. In this study, we consider various aspects of affordances in order to amplify the user experience via visualization and interaction design. SolarWheels visualizes the multilayer multidimensional computer network issues with a series of integrated circular visualizations inspired by the metaphor of the solar system. To amplify user interaction and experience, the system provides a three-zone physical interaction that allows multiple users to interact with the system. Users can read details at different levels depending on their distance from the display. An expert evaluation study, based on a four-layer affordance framework, was conducted to assess and improve the interactive visualization design.

  14. Ozone Bioindicator Gardens: an Educational Tool to Raise Awareness about Environmental Pollution and its Effects on Living Systems

    High concentrations of ground-level ozone cause health problems in humans and a number of negative effects on plants, from reduced yield for major agricultural crops to reduced amounts of carbon stored in trees. The Denver Metro/Colorado Front Range is exceeding the National Ambient Air Quality Standard for ozone on a regular basis in summer and the efforts to reduce the ozone levels are hampered by the presence of diverse pollution sources and complex meteorology in the region. To raise public awareness of air quality in the Colorado Front Range and to educate all age groups about ground-level ozone, two ozone bioindicator gardens were planted in Boulder in Spring 2014. The gardens contain ozone-sensitive plants that develop a characteristic ozone injury when exposed to high levels of ozone. The ozone gardens are providing the general public with a real-life demonstration of the negative effects of ozone pollution through observable plant damage. Additionally, the gardens are useful in teaching students how to collect and analyze real-world scientific data.

  15. Eating like there's no tomorrow: Public awareness of the environmental impact of food and reluctance to eat less meat as part of a sustainable diet.

    Reducing meat consumption is central to many of the scientific debates on healthy, sustainable diets because of the high environmental impact of meat production. Missing from these debates are the public perspectives about eating less meat and consideration of cultural and social values associated with meat. The aim of this study was to explore public awareness of the environmental impact of food and their willingness to reduce meat consumption. Twelve focus groups and four individual interviews were conducted with adults from a range of socio-economic groups living in both rural and urban settings in Scotland. Public understanding of the link between food, environment and climate change was explored, with a focus on meat and attitudes towards reducing meat consumption. Data were transcribed and analysed thematically. Three dominant themes emerged: a lack of awareness of the association between meat consumption and climate change, perceptions of personal meat consumption playing a minimal role in the global context of climate change, and resistance to the idea of reducing personal meat consumption. People associated eating meat with pleasure, and described social, personal and cultural values around eating meat. Some people felt they did not need to eat less meat because they had already reduced their consumption or that they only ate small quantities. Scepticism of scientific evidence linking meat and climate change was common. Changing non-food related behaviours was viewed as more acceptable and a greater priority for climate change mitigation. The study highlights the role meat plays in the diet for many people, beyond nutritional needs. If healthy, sustainable dietary habits are to be achieved, cultural, social and personal values around eating meat must be integrated into the development of future dietary recommendations.

  16. Quantifying the total cost of infrastructure to enable environmentally preferable decisions: the case of urban roadway design

    International Nuclear Information System (INIS)

    Gosse, Conrad A; Clarens, Andres F

    2013-01-01

    Efforts to reduce the environmental impacts of transportation infrastructure have generally overlooked many of the efficiencies that can be obtained by considering the relevant engineering and economic aspects as a system. Here, we present a framework for quantifying the burdens of ground transportation in urban settings that incorporates travel time, vehicle fuel and pavement maintenance costs. A Pareto set of bi-directional lane configurations for two-lane roadways yields non-dominated combinations of lane width, bicycle lanes and curb parking. Probabilistic analysis and microsimulation both show dramatic mobility reductions on road segments of insufficient width for heavy vehicles to pass bicycles without encroaching on oncoming traffic. This delay is positively correlated with uphill grades and increasing traffic volumes and inversely proportional to total pavement width. The response is nonlinear with grade and yields mixed uphill/downhill optimal lane configurations. Increasing bicycle mode share is negatively correlated with total costs and emissions for lane configurations allowing motor vehicles to safely pass bicycles, while the opposite is true for configurations that fail to facilitate passing. Spatial impacts on mobility also dictate that curb parking exhibits significant spatial opportunity costs related to the total cost Pareto curve. The proposed framework provides a means to evaluate relatively inexpensive lane reconfiguration options in response to changing modal share and priorities. These results provide quantitative evidence that efforts to reallocate limited pavement space to bicycles, like those being adopted in several US cities, could appreciably reduce costs for all users.

    Full Text Available A kinetic determination of V(V as a catalyst was spectrophotometrically performed by using the indicator reaction of Gallamine blue (GB+ and bromate at pH 2.0. The reaction was followed by measuring absorbance change for a fixed-time of 3 min at 537 nm. The variables such as reagent concentration, pH, buffer concentration, ionic strength and temperature were optimized to improve the selectivity and sensitivity. Under the optimized conditions, the determination of V(V was performed in the range 1–100 μg L−1 with limits of detection and quantification of 0.31 and 0.94 μg L−1. The developed kinetic method is sufficiently sensitive, selective and simple. It was successfully applied to the speciative determination of total V and inorganic dissolved vanadium species, V(V and V(IV in environmental water samples. The oxidizing property of permanganate is used to differentiate between V(IV and V(V species. The V(IV content was found by subtracting the V(V content from those of total V. The recovery is above 95% for V(V spiked samples. Additionally, the accuracy was validated by analysis of a certified water sample, CRM TMDA-53.3, and the results were in good agreement with the certified value.

    We use the WRF system to study the impacts of biomass burning smoke from Central America on several tornado outbreaks occurring in the US during spring. The model is configured with an aerosol-aware microphysics parameterization capable of resolving aerosol-cloud-radiation interactions in a cost-efficient way for numerical weather prediction (NWP) applications. Primary aerosol emissions are included and smoke emissions are constrained using an inverse modeling technique and satellite-based AOD observations. Simulations turning on and off fire emissions reveal smoke presence in all tornado outbreaks being studied and show an increase in aerosol number concentrations due to smoke. However, the likelihood of occurrence and intensification of tornadoes is higher due to smoke only in cases where cloud droplet number concentration in low level clouds increases considerably in a way that modifies the environmental conditions where the tornadoes are formed (shallower cloud bases and higher low-level wind shear). Smoke absorption and vertical extent also play a role, with smoke absorption at cloud-level tending to burn-off clouds and smoke absorption above clouds resulting in an increased capping inversion. Comparing these and WRF-Chem simulations configured with a more complex representation of aerosol size and composition and different optical properties, microphysics and activation schemes, we find similarities in terms of the simulated aerosol optical depths and aerosol impacts on near-storm environments. This provides reliability on the aerosol-aware microphysics scheme as a less computationally expensive alternative to WRFChem for its use in applications such as NWP and cloud-resolving simulations.

    Full Text Available This exploratory study had the objective of analyzing issues concerning environmental themes among students coming from four different areas of knowledge, at a public university in the State of Minas Gerais. By the use of drawings, the students’ environmental concepts were identified. Global environmental and campus problems, aswell as actions towards minimizing them, were investigated by using an open questionnaire. Independent of their performing area, a high number of students presented a reductionist view of the environment. Those from the areas related to natural sciences identified a higher number of problems at local and global levels than those from the areas known as humanities and math. The obtained data suggest the need for environmental education programs, which angle for greater student awareness in the search for sustainability and foster them to think about the current social model that we live in.Este estudo exploratório objetivou analisar questões referentes àtemática ambiental entre discentes, provenientes de quatro diferentes áreas do saber, de uma universidade pública do Estado de Minas Gerais.

    . According to our analyses, there are no apparent ecologically desirable changes among the inhabitants of the region of Lake Balaton, and when examining the social differentiation of the trends, one does not find any sign of higher environmental awareness among young people — who, according to Eurobarometer surveys tend to show higher environmental sensitivity. The results of our measures show that the social differences are attributed, therefore, not to age groups, but to the degree of education and to philosophical belief. The questionnaire, which was conducted among the permanent population of the Balaton region also identified a huge gap between the values and the acceptance of the environmentally friendly forms of action. Even though environmental values usually score at the top of the pyramide of values, support for actions aiming at solving environmental problems is not too strong.

    The most critical step in almost all commonly used analytical procedures for Hg determination is the sample preparation due to its extreme volatility. One of the possible solutions of this problem is the application of methods for direct analysis of solid samples. The possibilities for solid sampling high resolution continuum source atomic absorption spectrometry (HR CS AAS) determination of total mercury in various marine environmental samples e.g. sediments and biota are object of the present study. The instrumental parameters were optimized in order to obtain reproducible and interference free analytical signal. A calibration technique based on the use of solid standard certified reference materials similar to the nature of the analyzed sample was developed and applied to various CRMs and real samples. This technique allows simple and reliable evaluation of the uncertainty of the result and the metrological characteristics of the method. A validation approach in line with the requirements of ISO 17025 standard and Eurachem guidelines was followed. With this in mind, selectivity, working range (0.06 to 25 ng for biota and 0.025 to 4 ng for sediment samples, expressed as total Hg) linearity (confirmed by Student's t-test), bias (1.6-4.3%), repeatability (4-9%), reproducibility (9-11%), and absolute limit of detection (0.025 ng for sediment, 0.096 ng for marine biota) were systematically assessed using solid CRMs. The relative expanded uncertainty was estimated at 15% for sediment sample and 8.5% for marine biota sample (k = 2). Demonstration of traceability of measurement results is also presented. The potential of the proposed analytical procedure, based on solid sampling HR CS AAS technique was demonstrated by direct analysis of sea sediments form the Caribbean region and various CRMs. Overall, the use of solid sampling HR CS AAS permits obtaining significant advantages for the determination of this complex analyte in marine samples, such as straightforward

    The concentration of trace elements in tissues of several animals collected in the Ha Nam province, about 25 km south of Hanoi, Vietnam, has been investigated using total-reflection x-ray fluorescence (TXRF). With this study we wanted to address whether any of the animals were possible candidates for being bio-monitors for the pollution situation in a selected area of Vietnam. We also aim to compare the measured trace element concentrations to those representative to other provinces in Vietnam as well as to other parts of the world. An extensive bio-diversity of animals exists in Vietnam, where many of them play an important economic role in the agricultural breeding and production. The accumulation process of trace elements is still not known for a large number of animals. The parts of the collected animals chosen for analysis were muscle tissue and liver. The specimens were dried under vacuum and kept frozen. Before the TXRF analysis, the solid and dried samples were digested in nitric acid. The analysis was made at the Department of Physics at Chalmers University of Technology and Goeteborg University, Sweden, where a TXRF spectrometer has been developed by the Environmental Physics group. The results show that there could be a large variation in the concentration of trace elements, not only between the different animals but also between tissue parts of the same animal. Obviously, when selecting an organism to be used as a bio-monitor, other factors than the mere concentration of trace elements must be considered. (author)

    Full Text Available In this article, we advance the concept of “evolutionary awareness,” a metacognitive framework that examines human thought and emotion from a naturalistic, evolutionary perspective. We begin by discussing the evolution and current functioning of the moral foundations on which our framework rests. Next, we discuss the possible applications of such an evolutionarily-informed ethical framework to several domains of human behavior, namely: sexual maturation, mate attraction, intrasexual competition, culture, and the separation between various academic disciplines. Finally, we discuss ways in which an evolutionary awareness can inform our cross-generational activities—which we refer to as “intergenerational extended phenotypes”—by helping us to construct a better future for ourselves, for other sentient beings, and for our environment.

    Studies on the environmental analysis of biofuels by fast pyrolysis and hydroprocessing (BFPH) have so far focused only on the environmental impacts from direct emissions and have included few indirect emissions. The influence of ignoring some indirect emissions on the environmental performance of BFPH has not been well investigated and hence is not really understood. In addition, in order to avoid shifting environmental problems from one medium to another, a comprehensive assessment of environmental impacts caused by the processes must quantify the environmental emissions to all media (air, water, and land) in relation to each life cycle stage. A well-to-wheels assessment of the total environmental impacts resulting from direct emissions and indirect emissions of a BFPH system with corn stover is conducted using a hybrid life cycle assessment (LCA) model combining the economic input-output LCA and the process LCA. The Tool for the Reduction and Assessment of Chemical and other environmental Impacts (TRACI) has been used to estimate the environmental impacts in terms of acidification, eutrophication, global climate change, ozone depletion, human health criteria, photochemical smog formation, ecotoxicity, human health cancer, and human health noncancer caused by 1 MJ biofuel production. Taking account of all the indirect greenhouse gas (GHG) emissions, the net GHG emissions (81.8 g CO 2 eq/MJ) of the biofuels are still less than those of petroleum-based fuels (94 g CO 2 eq/MJ). Maize production and pyrolysis and hydroprocessing make major contributions to all impact categories except the human health criteria. All impact categories resulting from indirect emissions except eutrophication and smog air make more than 24% contribution to the total environmental impacts. Therefore, the indirect emissions are important and cannot be ignored. Sensitivity analysis has shown that corn stover yield and bio-oil yield affect the total environmental impacts of the biofuels

    Phytoplankton communities in freshwater lakes, ponds, and reservoirs may be dominated by cyanobacteria (also called blue-green algae) under certain environmental conditions. Cyanobacteria may cause a range of water-quality impairments, including the potential for toxin production. Cyanobacteria toxins (cyanotoxins) may adversely impact human and ecological health. Microcystins are considered to be one of the most commonly found classes of cyanotoxins in freshwater ecosystems, and as such were selected as a recreational indicator of water quality for the 2007 United States Environmental Protection Agency (EPA) National Lakes Assessment. However, much less is known about the occurrence of other classes of cyanotoxins in fresh surface water such as anatoxins, cylindrospermopsins, nodularins, and saxitoxins.

    Development of concepts and new technologies will have to pay more heed to the ecological balance of a product than in the past. The Umweltbundesamt (Federal Environmental Office) suggests to divide an ecological balance into a balance of facts, a balance of impact and include a balance sheet valuation. As there are no valid socio-political valuation criteria they suggest to use partial criteria as for instance the climate-relevant air pollution for the valuation of the refrigeration industry. This article attempts to forecast existing and foreseeable developments of the refrigeration industry under this particular aspect. (BWI) [de

    Due to the toxicity of chromium, species depend on their chemical properties and bioavailabilities, speciation of chromium is very important in environmental samples. A speciation procedure for chromium(III), chromium(VI) and total chromium in environmental samples is presented in this work, prior to flame atomic absorption spectrometric determination of chromium. The procedure is based on the adsorption of Cr(III)-diphenylcarbazone complex on Amberlite XAD-1180 resin. After oxidation of Cr(III), the developed solid phase extraction system was applied to determinate the total chromium. Cr(III) was calculated as the difference between the total Cr content and the Cr(VI) content. The analytical conditions for the quantitative recoveries of Cr(VI) on Amberlite XAD-1180 resin were investigated. The effects of some alkaline, earth alkaline, metal ions and also some anions were also examined. Preconcentration factor was found to be 75. The detection limits (LOD) based on three times sigma of the blank (N: 21) for Cr(VI) and total chromium were 7.7 and 8.6 μg/L, respectively. Satisfactory results for the analysis of total chromium in the stream sediment (GBW7310) certified reference material for the validation of the presented method was obtained. The procedure was applied to food, water and pharmaceutical samples successfully

    The objective of the Symposium for Public Awareness on Energy was to provide an information exchange among the members of the technical community and the public, civic, fraternal, service, and labor organizations on timely energy-related issues. The 1977 symposium was oriented toward state and local governmental officials in the southeastern states. Since it is these officials who have the responsibility for the development and actualization of local energy strategies, the program was directed toward providing information which would be of help to them in considering energy plans. The symposium presentations featured speakers who are recognized in many facets of the energy field. A variety of views were expressed and a number of policy alternatives were suggested. It is hoped that the presentations provided the motivation for the audience to return to their respective communities with a new and expanded perspective regarding energy issues and policies. The private and public organizations represented at the symposium can continue to provide pertinent information to those who are interested. A separate abstract was prepared for each of the 9 presentations.

    The determination of chlorine, bromine and iodine present as non-polar, hydrophobic hydrocarbons in environmental samples is reported. The organohalogen compounds are seprated from water into an organic phase by on-site liquid-liquid extraction, and form biological material by procedures based on lipid phase extraction and codistillation. After removal of inorganic halides by washing with water and concentration of the sample by evaporation of the solvent, the resulting extracts are analyzed for their chlorine, bromine and iodine contents by instrumental neutron activation analysus. Strict attention is paid to the possibility of contamination in every step of the procedure. Background values in routine analysis are approximately 100-200 ng of chlorine, <5 ng of bromine and <3 ng of iodine.

    Recently there is a growing interest in low Z elements such as carbon, oxygen up to sulphur and phosphorus in biological specimen. Total reflection X-ray fluorescence (TXRF) spectrometry is a suitable technique demanding only very small amounts of sample. On the other side, the detection of low Z elements is a critical point of this analytical technique. Besides other effects, self absorption may occur in the samples, because of the low energy of the fluorescence radiation. The calibration curves might be not linear any longer. To investigate this issue water samples and samples from human cerebrospinal fluid were used to examine absorption effects. The linearity of calibration curves in dependence of sample mass was investigated to verify the validity of the thin film approximation. The special requirements to the experimental setup for low Z energy dispersive fluorescence analysis were met by using the Atominstitute's TXRF vacuum chamber. This spectrometer is equipped with a Cr-anode X-ray tube, a multilayer monochromator and a SiLi detector with 30 mm 2 active area and with an ultrathin entrance window. Other object on this study are biofilms, living on all subaqueous surfaces, consisting of bacteria, algae and fungi embedded in their extracellular polymeric substances (EPS). Many trace elements from the water are bound in the biofilm. Thus, the biofilm is a useful indicator for polluting elements. For biomonitoring purposes not only the polluting elements but also the formation and growth rate of the biofilm are important. Biofilms were directly grown on TXRF reflectors. Their major elements and C-masses correlated to the cultivation time were investigated. These measured masses were related to the area seen by the detector, which was experimentally determined. Homogeneity of the biofilms was checked by measuring various sample positions on the reflectors

    This paper deals with how to evaluate the effectiveness of carbon tax (environmental tax) for regulating the carbon dioxide emissions. For this purpose we mainly deal with a primal problem and its dual problem of dynamic linear programming model. The primal problem is formulated by using Leontief type input-output model and the basic idea of commodity stocks. It represents the balance of materials. The dual problem is obtained and interpreted as cash balance. It is clarified in this paper whether the carbon tax is effective to decrease the total amount of carbon dioxide emissions. (author)

    With China’s entrance into the new economy, the improvement of energy efficiency has become an important indicator to measure the quality of ecological civilization construction and economic development. According to the panel data of Chinese regions in 1996-2014, the nearest distance to the efficient frontier of Undesirable-MinDS Xeon model and DEA window model have been used to calculate the total factor energy efficiency of China’s regions. Study found that: Under environmental constraints, China’s total factor energy efficiency has increased after the first drop in the overall 1996-2014, and then increases again. And the difference between the regions is very large, showing a characteristic of “the east is the highest, the west is lower, and lowest is in the central” finally, this paper puts forward relevant policy suggestions.

    Highlights: • V. parahaemolyticus densities in oysters were isolated in spring and winter seasons. • Pathogenic genes abundances varied with environmental parameters seasonal changes. • Water temperature modulated V. parahaemolyticus abundance during reduced salinities. • V. parahaemolyticus with potentially pathogenic genes raises important health issues. - Abstract: The influence of environmental parameters on the total and pathogenic Vibrio parahaemolyticus seasonal densities in American oysters (Crassostrea virginica) was evaluated for 1 year. Harvesting site A yielded the highest mean densities of V. parahaemolyticus tlh+, tdh+/trh−, tdh−/trh+ and tdh+/trh+ during spring season at 2.57, 1.74, 0.36, and −0.40 log 10 MPN/g, respectively, and tdh+/orf8+ during winter season (0.90 log 10 MPN/g). V. parahaemolyticus tlh+ densities were associated to salinity (R 2 = 0.372, P < 0.022), tdh+/trh+ to turbidity (R 2 = 0.597, P < 0.035), and orf8+ to temperature, salinity, and pH (R 2 = 0.964, P < 0.001). The exposure to salinity and temperature conditions during winter and spring seasons regulated the dynamics of V. parahaemolyticus harboring potentially pathogenic genotypes within the oyster. The adaptive response of V. parahaemolyticus to seasonal environmental changes may lead to an increase in survival and virulence, threatening the seafood safety and increasing the risk of illness

    In June 1998, the Brazilian-Argentine Agency for Accounting and Control of Nuclear Materials (ABACC), with assistance from the U.S. Department of Energy (DOE), began a program to assess environmental sampling and analysis capabilities at laboratories in Argentina and Brazil. The program began with staff training conducted in South America and the United States by Oak Ridge National Laboratory (ORNL) and Pacific Northwest National Laboratory (PNNL). Both laboratories are participating members of DOE's Network of Analytical Laboratories (NWAL) that support IAEA's environmental sampling program. During the initial planning meeting, representatives from ABACC and all the participating analytical laboratories supporting ABACC were briefed on how the first exercise would be managed and on key aspects necessary to analyze low-level environmental samples for uranium. Subsequent to this training, a laboratory evaluation exercise (Exercise 1) was conducted using standard swipe samples prepared for this exercise by the International Atomic Energy Agency (IAEA). The results of Exercise 1 determined that sample contamination was a major factor in the analysis, and a thorough review of laboratory procedures was required to reduce the level of contamination to acceptable levels. Following modification of sample preparation procedures, the laboratories performed Exercise 2, an analysis of a National Institute of Standards and Technology (NIST) Standard Reference Material (SRM) 1547, Peach Leaves. The results of Exercise 2 demonstrated that several laboratories were capable of accurately determining the total uranium and uranium isotopic distribution in the peach leaves. To build on these successes, Exercise 3 was performed using a series of standard swipe samples prepared by the IAEA and distributed to laboratories supporting ABACC and to PNNL and ORNL. The results of Exercise 3 demonstrate that ABACC now has support laboratories in both Argentina and Brazil, which are capable of

    Since the industrial revolution in the 1800s, plastic pollution is becoming a global reality. This study aims to assess knowledge and attitude about plastic pollution among secondary school students in Sharjah city, United Arab Emirates. A cross-sectional study was conducted among 400 students in 6 different secondary schools in Sharjah city. Self-administered questionnaires were distributed through probability stratified random sampling method between February and April 2016. Majority of the population understands how harmful plastic wastes are to the environment (85.5%). However, the students' mean knowledge score was 53%, with females (P < 0.01), grades 11 and 12 (P = 0.024), and students whose mothers were more educated (P = 0.014) being more knowledgeable and inclined towards pro-environmental behavior. Yet, all students showed tendency to be involved in the fighting against this dilemma. Strategies which address deficiencies, provide incentives for change, and assure governmental support along with environmental education are needed to bridge the information gap and enhance opportunities to adopt pro-environmental behaviors.

    A rapid and sensitive liquid chromatography quadrupole time of flight method has been established for the determination of total naphthenic acid concentrations in aqueous samples. This is the first methodology that has been adopted for routine, high resolution, high throughput analysis of total naphthenic acids at trace levels in unprocessed samples. A calibration range from 0.02 to 1.0μgmL(-1) total Merichem naphthenic acids was validated and demonstrated excellent accuracy (97-111% recovery) and precision (1.9% RSD at 0.02μgmL(-1)). Quantitative validation was also demonstrated in a non-commercial oil sands process water (OSPW) acid extractable organics (AEOs) fraction containing a higher percentage of polycarboxylic acid isomers than the Merichem technical mix. The chromatographic method showed good calibration linearity of ≥0.999 RSQ to 0.005μgmL(-1) total naphthenic acids with a precision <3.1% RSD and a calculated detection limit of 0.0004μgmL(-1) employing Merichem technical mix reference material. The method is well suited to monitoring naturally occurring and industrially derived naphthenic acids (and other AEOs) present in surface and ground waters in the vicinity of mining developments. The advantage of the current method is its direct application to unprocessed environmental samples and to examine natural naphthenic acid isomer profiles. It is noted that where the isomer profile of samples differs from that of the reference material, results should be considered semi-quantitative due to the lack of matching isomer content. The fingerprint profile of naphthenic acids is known to be transitory during aging and the present method has the ability to adapt to monitoring of these changes in naphthenic acid content. The method's total ion scan approach allows for data previously collected to be examined retrospectively for specific analyte mass ions of interest. A list of potential naphthenic acid isomers that decrease in response with aging is proposed

    Full Text Available Abstract Background The environmental factors that determine the elevated levels of polyclonal IgE observed in populations living in the Tropics are poorly understood but may include geohelminth infections. We investigated the association between geohelminth infections and total IgE levels in school children in rural tropical Ecuador, and assessed the effect on IgE of repeated anthelmintic treatments over a period of 12 months. The study was nested within a cluster-randomized study that randomized 68 schools to receive either 400 mg of albendazole every 2 months over a year or no treatment. We studied random samples of children completing follow-up and representing four groups stratified by the presence of geohelminth infection at baseline and treatment allocation. We measured levels of total IgE and anti-A. lumbricoides IgG (used as a measure of past and current geohelminth infectious exposure in blood samples collected at the start of the study and after 12 months. Results We observed elevated levels of total IgE (compared to standard reference values at the start of the study in this population of school children (geometric mean, 1,004 IU/mL, range 12 to 22,608 IU/mL and baseline IgE levels were strongly associated with parameters of geohelminth infection but not with age, nutritional and socioeconomic status. After 12 months, levels of IgE fell significantly in the treatment (by 35.1% and no treatment (by 10.4% groups, respectively, but the fall was significantly greater in the treatment group. Falls in IgE were independently associated with albendazole treatment, having a baseline geohelminth infection and with high baseline levels of anti-A. lumbricoides IgG. Increases in IgE at 12 months were associated with the presence of geohelminth infections and increasing levels of anti-A. lumbricoides IgG at 12 months independent of treatment allocation. Conclusion The data provide evidence that geohelminth infections are an important determinant

    In environmental research and protection trace elements have to be determined over a wide range of atomic number, down to very low concentrations, and in quite different matrices. This challenge requires the availability of complementary analytical methods characterized by a high detection power and few sources of systematic errors. Besides, the capacity of multielement detection is often desired since it facilitates the talking of many problems in which numerous trace elements are of direct concern. Total-reflection X-ray fluorescence, neutron activation analysis and inductively coupled plasma optical emission spectroscopy, in principle fulfill these requirements quite well. However, each method has its domain, and the application to certain sample species may be less promising. Under this aspect, the paper summarizes some recent developments and investigations, including intercomparisons as far as possible. Various matrices are considered : rainwater and airborne particulates, soil samples, river sediments and suspended particulate matter, river water filtrates, ozean water, and organic matrices. Capabilities and limitations are discussed. Sample preparation techniques are described if they are new or essential for achieving the results given. (orig.) [de

    Cardiac surgery represents a sub-group of patients at significantly increased risk of intraoperative awareness. Relatively few recent publications have targeted the topic of awareness in this group. The aim of this review is to identify areas of awareness research that may equally be extrapolated to cardiac anesthesia in the attempt to increase understanding of the nature and significance of this scenario and how to reduce it.

  1. Quantized Visual Awareness

    Directory of Open Access Journals (Sweden)

    W Alexander Escobar

    2013-11-01

    Full Text Available The proposed model holds that, at its most fundamental level, visual awareness is quantized. That is to say that visual awareness arises as individual bits of awareness through the action of neural circuits with hundreds to thousands of neurons in at least the human striate cortex. Circuits with specific topologies will reproducibly result in visual awareness that correspond to basic aspects of vision like color, motion and depth. These quanta of awareness (qualia are produced by the feedforward sweep that occurs through the geniculocortical pathway but are not integrated into a conscious experience until recurrent processing from centers like V4 or V5 select the appropriate qualia being produced in V1 to create a percept. The model proposed here has the potential to shift the focus of the search for visual awareness to the level of microcircuits and these likely exist across the kingdom Animalia. Thus establishing qualia as the fundamental nature of visual awareness will not only provide a deeper understanding of awareness, but also allow for a more quantitative understanding of the evolution of visual awareness throughout the animal kingdom.

  2. Environmental Awareness on Beef Cattle Technology

    Full Text Available The acceleration program to meet beef self sufficient in 2010 is expected to increase animal protein consumption of Indonesian people in order to be equal with other countries as well as to improve the livestock farmer’s income. The main objective of the program is to increase cattle population. Since the availability of forage and grassland is limited, beef cattle development is driven to the crop and plantation integration approach by using their by-product as cattle feed. Crop and plantation by-products, generally are considered to be fiber source with high lignocellulose’s and low nutritive value. Feeding high fiber would increase methane gas production, and faeces and grass cultivation also contributed on greenhouse emission. Methane is one of the main greenhouse gases contributed by agriculture sector; increasing beef cattle population using high fiber feed is predicted to increase methane production. Good management is expected to improve productivity and to reduce methane production on livestock. Some efforts could be done such as good feeding management and nutrition manipulation, environment friendly cattle waste management, improving management on roughage cultivation, and improving management on cattle production.

    Full Text Available Multicultural awareness is the foundation of communication and it involves the ability of standing back from ourselves and becoming aware of our cultural values, beliefs and perceptions. Multicultural awareness becomes central when we have to interact with people from other cultures. People see, interpret and evaluate things in a different ways. What is considered an appropriate behaviour in one culture is frequently inappropriate in another one. this research use descriptive- quantitative methodology to indentify level of students multicultural awareness specifically will be identified by gender and academic years. This research will identify multicultural awareness based on differences of gender, academic years. This research use random and purposive random sampling of 650 students from university. These studies identify of multicultural awareness 34, 11, 4% in high condition, 84, 1% medium and 4, 5% in low. Further, there is a significant difference in the level of multicultural awareness based on gender and academic year. These findings could not be generalized because of the limited sample and ethnicity; it should need a wider research so that can be generalized and recommended the efforts to development and improvement of multicultural awareness conditions for optimization the services.

    This work deals with the results of an ecological/psychological study into the development of Zagreb inhabitants awareness of the potential health risks posed by the ten most significant forms of environmental pollution and into how each examinee influences the development of ecological consciousness. This research was conducted with representative population sample of two significantly differently ecologically critical Zagreb communities: the shanty town community of Kozari Bokand the highly urbanized community of Slobostina. The survey was conducted on site using the Liekert scale in 1990. The results have shown that air and water pollution are considered potentially most dangerous, as opposed to the total lack of awareness concerning noise pollution. The factors significant in the formation of ecological awareness are: occupation and the perception of immediate danger as opposed to age, sex and personal background. However, the subject's educational level and familiarity with the relevant facts are crucial elements affecting the awakening and development of ecological consciousness.

    1999-07-01

    Situation awareness encompasses a knowledge of orders, plans and current knowledge of friendly force actions. Knowing where you are and being able to transmit that information in near real-time to other friendly forces provides the ability to exercise precise command and control over those forces. With respect to current command and control using voice methods, between 40 percent and 60 percent of Combat Net Radio traffic relates to location reporting of some sort. Commanders at Battle Group and below spend, on average, 40 percent of their total time performing position and navigation related functions. The need to rapidly transfer own force location information throughout a force and to process the received information quickly, accurately and reliably provides the rationale for the requirement for an automated situation awareness system. This paper describes the Situation Awareness System (SAS) being developed by Computing Devices Canada for the Canadian Department of National Defence as a component of the Position Determination and Navigation for Land Forces program. The SAS is being integrated with the Iris Tactical Command, Control, Communications System, which is also being developed by Computing Devices. The SAS software provides a core operating environment onto which command and control functionality can be easily added to produce general and specialist battlefield management systems.

    This systematic review synthesizes the complex literature on prognostic awareness in cancer. A total of 37 studies examining cancer patients' understanding of their prognosis were included. Prognostic awareness definitions and assessment methods were inconsistent across studies. A surprisingly high percentage of patients (up to 75%) were unaware of their poor prognosis, and in several studies, even their cancer diagnosis (up to 96%), particularly in studies conducted outside of North America. This review highlights surprisingly low rates of prognostic awareness in patients with advanced cancer as well as discrepancies in prognostic awareness assessment, suggesting the need for empirically validated measures of prognostic awareness. © The Author(s) 2013.

Females were more likely to think that autistic children can be employed in the future (p=0.008), whereas males were more likely to think that autism is similar to mental retardation (p=0.005). The public awareness of ASD needs improvement. Areas for targeted education were identified to help improve the quality of life of autistic children and their families.

  5. Some Environmental and Economic Aspects of Energy Saving Measures in Houses. An estimation model for total energy consumption and emissions to air from the Norwegian dwelling stock, and a life cycle assessment method for energy saving measures in houses

    Energy Technology Data Exchange (ETDEWEB)

    Myhre, L

    1995-12-01

    Motivated by the need to reduce the total energy consumption and the environmental load from society, this doctoral thesis discusses energy conservation measures on existing houses. Alternative additional thermal insulation measures are assessed using an interdisciplinary life cycle approach. The first task is to develop an interdisciplinary assessment method for building improvement measures, taking account of energy consumption, resource consumption, emissions to air of environmentally harmful gases, and economic costs during the entire life cycle of the building. The second task is to develop an estimation model for the total energy consumption and emissions to air of environmentally harmful gases from the dwelling stock of Norway. Finally, the third task is to assess the total energy saving potential and the total environmental benefits of energy saving measures in houses on a national level, including only life cycle analyses of additional thermal insulation measures on single houses. Chap 2 describes the dwelling stock in Norway. Chaps 3 and 4 present an estimation model for total energy consumption and emissions to air from the dwelling stock, and calculations using the model. Chaps 5 and 6 propose and use a calculation method for the assessment of additional thermal insulation measures, using a ``cradle-to-grave`` approach. Since hydroelectric power is the main energy source in this sector in Norway, estimated payback periods for emissions to air are long. But hydroelectric power saved in this sector may be used to obtain reduction in fossil fuel use in other sectors as discussed in Chap 7. Some of the topics discussed are further elaborated on in appendices. 107 refs., 39 figs, 88 tabs.

    2007-01-01

    The effect of matrix contents on the detection limit of total reflection X-ray fluorescence analysis was experimentally investigated using a set of multielement standard solutions (500 ng/mL of each element) in variable concentrations of NH 4 NO 3 . It was found that high matrix concentration, i.e. 0.1-10% NH 4 NO 3 , had a strong effect on the detection limits for all investigated elements, whereas no effect was observed at lower matrix concentration, i.e. 0-0.1% NH 4 NO 3 . The effect of soil and blood sample masses on the detection limit was also studied. The results showed decreasing the detection limit (in concentration unit, μg/g) with increasing the sample mass. However, the detection limit increased (in mass unit, ng) with increasing sample mass. The optimal blood sample mass of ca. 200 μg was sufficient to improve the detection limit of Se determination by total reflection X-ray fluorescence. The capability of total reflection X-ray fluorescence to analyze different kinds of samples was discussed with respect to the accuracy and detection limits based on certified and reference materials. Direct analysis of unknown water samples from several sources was also presented in this work

    2011-12-01

    In order to be able to assess the level of awareness of swallowing disorders in Parkinson's disease (PD), a specific questionnaire was designed and validated: the Dysphapark questionnaire. A total of 470 persons with PD were asked whether they believe they have problems swallowing or not, and then they filled in a self-administered questionnaire that evaluates the effectiveness and safety of swallowing. The Dysphapark questionnaire was validated by means of Rasch analysis and classical psychometric methods. The safety and effectiveness dimensions of the Dysphapark fit the Rasch model well. The efficacy dimension showed significant differences for gender, length of the illness, awareness of dysphagia and length of meals. Significant differences were also found in the safety dimension for length and severity of illness, awareness of dysphagia, speech therapy and knowledge of thickening agents. Despite the fact that 90% of patients had problems concerning effectiveness and safety in swallowing, 79.45% were not aware that they suffered from dysphagia. The Dysphapark questionnaire is a suitable measure of dysphagia in PD, according to the Rasch analysis. A high proportion of patients with PD have dysphagia, although it has been observed that they have a low level of awareness of the condition, of the consequences it may have and of the possibility of using thickening agents. Given that some of the swallowing disorders in PD are asymptomatic and that the level of awareness of the disorder is low, we recommend including specific questionnaires as well as clinical and instrumental evaluation of dysphagia in clinical practice.

    The Air Force's Space & Missile Systems Center (SMC) SENSE mission consists of two identical cubesat buses with space weather payloads. One of the goals of the SENSE mission is to demonstrate the operational potential and usefulness of space weather measurements from a cubesat platform. The payloads on the two cubesats include the Cubesat Tiny Ionospheric Photometer (SRI), Wind Ion Neutral Composite Suite (NRL), and Compact Total Electron Content GPS radio occultation sensor (CTECS). After initial contact with both space vehicles (SV), we were able to confirm successful operation of both CTECS. Because of power issues on SV2, only SV1 has provided consistent data. In this presentation, we present an overview of the CTECS sensor. Then we present initial CTECS data, discuss the data quality, and lessons learned.

    Background Despite the importance of body awareness for health and well-being there is still a lack of valid assessment tools to scan proper body awareness. To respond to the limitations of questionnaires (reading/interpretation problems) the Awareness-Body-Chart (ABC) was designed to assess body awareness by colouring 51 regions according to their awareness. The objective of this study was to investigate the psychometric characteristics of the ABC. Methods In a questionnaire-study, 106 students in Graz (79 females, 27 males, age median 21 (IQR 20–23) years) filled in the ABC, furthermore a German body awareness questionnaire „KEKS”, and the Beck Depression Inventory II. Factor structure, internal consistency, and retest reliability of the ABC were investigated. Correlations of the ABC with the KEKS and the Beck Depression Inventory II and comparisons of subgroups were conducted. Results Through factor analyses, 14 factors with clear assignments to body parts could be categorized: cranium, face, cervical/lumbar region, chest/abdomen, back, shoulder, upper arm, lower arm/elbow, hand, genital area, thigh/hip, knee, lower leg, and foot. The 14 body parts and the total score showed acceptable to high Cronbach’s alphas (α = .64 - .97). The test-retest reliability showed values between ρ = .71 and ρ = .96.

  4. Are environmental characteristics in the municipal eldercare, more closely associated with frequent short sick leave spells among employees than with total sick leave: a cross-sectional study

    Science.gov (United States)

    2013-01-01

    Background It has been suggested that frequent-, short-term sick leave is associated with work environment factors, whereas long-term sick leave is associated mainly with health factors. However, studies of the hypothesis of an association between a poor working environment and frequent short spells of sick leave are few and results are inconsistent. Therefore, we aimed to explore associations between self-reported psychosocial work factors and workplace-registered frequency and length of sick leave in the eldercare sector. Methods Employees from the municipal eldercare in Aarhus (N = 2,534) were included. In 2005, they responded to a work environment questionnaire. Sick leave records from 2005 were dichotomised into total sick leave days (0–14 and above 14 days) and into spell patterns (0–2 short, 3–9 short, and mixed spells and 1–3 long spells). Logistic regression models were used to analyse associations; adjusted for age, gender, occupation, and number of spells or sick leave length. Results The response rate was 76%; 96% of the respondents were women. Unfavourable mean scores in work pace, demands for hiding emotions, poor quality of leadership and bullying were best indicated by more than 14 sick leave days compared with 0–14 sick leave days. For work pace, the best indicator was a long-term sick leave pattern compared with a non-frequent short-term pattern. A frequent short-term sick leave pattern was a better indicator of emotional demands (1.62; 95% CI: 1.1-2.5) and role conflict (1.50; 95% CI: 1.2-1.9) than a short-term non-frequent pattern. Age (= 40 years) statistically significantly modified the association between the 1–3 long-term sick leave spell pattern and commitment to the workplace compared with the 3–9 frequent short-term pattern. Conclusions Total sick leave length and a long-term sick leave spell pattern were just as good or even better indicators of unfavourable work factor scores than a frequent short-term sick leave

    Geraldo, S. M.; Canteras, F. B.; Moreira, S.

    2014-02-01

    Currently, many studies use the bioindicators to qualitatively and/or quantitatively measure pollution. The analyses of tree growth rings represent one such bioindicator as changes in the environment are often recorded as impressions in the wood. The main objective of the present study is to examine the growth rings of Tipuana tipu - a member of the Leguminosae family that is native to Argentina and Bolivia and was introduced in Brazil as an ornamental plant - for potentially toxic elements. T. tipu is one of the most common trees in the urban landscape of Sao Paulo city and would provide an accurate reflection of environment changes. Tree ring samples previously dated using Synchrotron Radiation Total Reflection X-ray Fluorescence were collected from strategic locations in Sao Paulo. These locations include Piracicaba (SP) that has little access and small flow traffic and the campus of the University of São Paulo. Some trace elements present concentrations higher than considered as normal in some periods. In São Paulo city, samples collected from the campus of University of São Paulo (Butantã), showed the highest toxicity, with concentrations above the tolerable limit for the elements: Cr, Cu, and Pb. For the samples collected in Piracicaba city, one sample presented highest concentrations for the majority of the elements when compared to the other four samples collected at the same place, exceeding the toxicity limits for: Cr, Ni, Cu, and Pb.

  7. The environmental literacy of urban middle school teachers

    Science.gov (United States)

    Owens, Marcia Allen

    This dissertation study assessed the environmental literacy of 292 urban, middle school teachers using the Wisconsin Environmental Literacy Survey (WELS). Environmental literacy may be defined in terms of observable behaviors. Specifically, the study examined four dimensions of participants' environmental literacy: (a) attitudes toward the environment, (b) beliefs about their own power and responsibility to affect environmental change, (c) personal behaviors and actions toward the environment, and (d) knowledge regarding ecology and environmental issues. The WELS measures these components of environmental literacy through a Likert-type attitude survey, a self-reporting behavior instrument, and a multiple choice measure of cognitive learning outcomes or environmental knowledge. These scores were combined to derive a total environmental literacy score. In addition, the study explored differences between African American and European American female teachers' environmental literacy; interactions between demographic variables; and patterns of frequently missed questions, environmental attitudes, or environmental behaviors. Differences in teachers' environmental literacy were examined relative to gender, racial/ethnic background, number of preservice environmental courses taken, number of inservice environmental courses taken, years of teaching experience, and subject area taught. Overall, teachers in the present study demonstrated nominal environmental literacy. Significant differences in scores on various subscales were found among teachers according to racial/ethnic background, subject area taught, and years of teaching experience. Taking preservice and inservice environmental courses appears to have a positive impact on environmental behavior, environmental sensitivity, awareness and values, but not appear to impact environmental knowledge. This study underscores the need for further descriptive environmental literacy research on urban, minority, and poor students

    2016-06-01

    Full Text Available Total thyroidectomy is a surgery that removes all the thyroid tissue from the patient. The suspect of cancer in a thyroid nodule is the most frequent indication and it is presume when previous fine needle puncture is positive or a goiter has significant volume increase or symptomes. Less frequent indications are hyperthyroidism when it is refractory to treatment with Iodine 131 or it is contraindicated, and in cases of symptomatic thyroiditis. The thyroid gland has an important anatomic relation whith the inferior laryngeal nerve and the parathyroid glands, for this reason it is imperative to perform extremely meticulous dissection to recognize each one of these elements and ensure their preservation. It is also essential to maintain strict hemostasis, in order to avoid any postoperative bleeding that could lead to a suffocating neck hematoma, feared complication that represents a surgical emergency and endangers the patient’s life.It is essential to run a formal technique, without skipping steps, and maintain prudence and patience that should rule any surgical act.

  12. Sonic morphology: Aesthetic dimensional auditory spatial awareness

    Science.gov (United States)

    Whitehouse, Martha M.

    The sound and ceramic sculpture installation, " Skirting the Edge: Experiences in Sound & Form," is an integration of art and science demonstrating the concept of sonic morphology. "Sonic morphology" is herein defined as aesthetic three-dimensional auditory spatial awareness. The exhibition explicates my empirical phenomenal observations that sound has a three-dimensional form. Composed of ceramic sculptures that allude to different social and physical situations, coupled with sound compositions that enhance and create a three-dimensional auditory and visual aesthetic experience (see accompanying DVD), the exhibition supports the research question, "What is the relationship between sound and form?" Precisely how people aurally experience three-dimensional space involves an integration of spatial properties, auditory perception, individual history, and cultural mores. People also utilize environmental sound events as a guide in social situations and in remembering their personal history, as well as a guide in moving through space. Aesthetically, sound affects the fascination, meaning, and attention one has within a particular space. Sonic morphology brings art forms such as a movie, video, sound composition, and musical performance into the cognitive scope by generating meaning from the link between the visual and auditory senses. This research examined sonic morphology as an extension of musique concrete, sound as object, originating in Pierre Schaeffer's work in the 1940s. Pointing, as John Cage did, to the corporeal three-dimensional experience of "all sound," I composed works that took their total form only through the perceiver-participant's participation in the exhibition. While contemporary artist Alvin Lucier creates artworks that draw attention to making sound visible, "Skirting the Edge" engages the perceiver-participant visually and aurally, leading to recognition of sonic morphology.

    The aim of this study is to assess the Arab society's knowledge, awareness, and attitudes toward dental veneers. A cross-sectional study was performed by collecting data through an online questionnaire created using the Survey Monkey website and distributed among Middle Eastern societies through social media to ascertain participants' knowledge and awareness regarding dental veneers. The sample included Arab laypeople who were over 18 years old, to represent the awareness of the majority regarding dental veneers. The sample of this study included 1,332 subjects from different Middle Eastern nationalities, mainly Saudis, Kuwaitis, and Emiratis (15.6% of males and 84.4% of females). The results of this study showed that the total knowledge of dental veneers is 50.12%. The respondents with the highest level of knowledge acquired their information mainly from newspapers and magazines, followed by the Internet, then dentists, then social media, and, finally, friends and relatives. Cost was the only factor limiting 38.4% of subjects from receiving veneers, and 56% of the subjects would receive veneers if they were free of cost. In total, 72.6% of the respondents believed that veneers are currently overused. The knowledge and awareness of dental veneers were below a satisfactory level. Participants who relied on social media as a source of information had lower knowledge levels. This study emphasized the need for continual societal education regarding dental veneers.

  16. Awareness of deficits in traumatic brain injury: a multidimensional approach to assessing metacognitive knowledge and online-awareness.

    O'Keeffe, Fiadhnait

    2007-01-01

    Recent models of impaired awareness in brain injury draw a distinction between metacognitive knowledge of difficulties and online awareness of errors (emergent and anticipatory). We examined performance of 31 Traumatic Brain Injury (TBI) participants and 31 healthy controls using a three-strand approach to assessing awareness. Metacognitive knowledge was assessed with an awareness interview and discrepancy scores on three questionnaires--Patient Competency Rating Scale, Frontal Systems Behavioral Scale and the Cognitive Failures Questionnaire. Online Emergent Awareness was assessed using an online error-monitoring task while participants performed tasks of sustained attention. Online anticipatory awareness was examined using prediction performance on two cognitive tasks. Results indicated that the TBI Low Self-Awareness (SA) group and High SA group did not differ in terms of severity, chronicity or standard neuropsychological tasks but those with Low SA were more likely to exhibit disinhibition, interpersonal problems and more difficulties in total competency. Sustained attention abilities were associated with both types of online awareness (emergent and anticipatory). There was a strong relationship between online emergent and online anticipatory awareness. Metacognitive knowledge did not correlate with the other two measures. This study highlights the necessity in adopting a multidimensional approach to assessing the multifaceted phenomenon of awareness of deficits.

  17. Determination of inorganic mercury and total mercury in biological and environmental samples by flow injection-cold vapor-atomic absorption spectrometry using sodium borohydride as the sole reducing agent

    A simple, fast, precise and accurate method to determine inorganic mercury and total mercury in biological and environmental samples was developed. The optimized flow-injection mercury system permitted the separate determination of inorganic mercury and total mercury using sodium borohydride as reducing agent. Inorganic mercury was selectively determined after reduction with 10 -4 % w/v sodium borohydride, while total mercury was determined after reduction with 0.75% w/v sodium borohydride. The calibration graphs were linear up to 30 ng ml -1 . The detection limits of the method based on three times the standard deviation of the blank were 24 and 3.9 ng l -1 for total mercury and inorganic mercury determination, respectively. The relative standard deviation was less than 1.5% for a 10 ng ml -1 mercury standard. As a means of checking method performance, deionized water and pond water samples were spiked with methylmercury and inorganic mercury; quantitative recovery for total mercury and inorganic mercury was obtained. The accuracy of the method was verified by analyzing alkaline and acid extracts of five biological and sediment reference materials. Microwave-assisted extraction procedures resulted in higher concentrations of recovered mercury species, lower matrix interference with mercury determination and less time involved in sample treatment than conventional extraction procedures. The standard addition method was only needed for calibration when biological samples were analyzed. The detection limits were in the range of 1.2-19 and 6.6-18 ng g -1 in biological and sediment samples for inorganic mercury and total mercury determination, respectively

    Full Text Available Libet et al. (1983 revealed that brain activity precedes conscious intention. For convenience in this study, we divide brain activity into two parts: a conscious field (CF and an unconscious field (UF. Most studies have assumed a comparator mechanism or an illusion of CF and discuss the difference of prediction and postdiction. We propose that problems to be discussed here are a twisted sense of agency between CF and UF, and another definitions of prediction and postdiction in a mediation process for the twist. This study specifically examines the definitions throughout an observational heterarchy model based on internal measurement. The nature of agency must be emergence that involves observational heterarchy. Consequently, awareness involves processes having duality in the sense that it is always open to the world (postdiction and that it also maintains self robustly (prediction.

    The arc of the Milky Way seen from a truly dark location is part of our planet's natural heritage. More than one fifth of the world population, two thirds of the United States population and one half of the European Union population have already lost naked eye visibility of the Milky Way. This loss, caused by light pollution, is a serious and growing issue that impacts astronomical research, the economy, ecology, energy conservation, human health, public safety and our shared ability to see the night sky. For this reason, "Dark Skies” is a cornerstone project of the International Year of Astronomy. Its goal is to raise public awareness of the impact of artificial lighting on local environments by getting people worldwide involved in a variety of programs that: 1. Teach about dark skies using new technology (e.g., an activity-based planetarium show on DVD, podcasting, social networking on Facebook and MySpace, a Second Life presence) 2. Provide thematic events on light pollution at star parties and observatory open houses (Dark Skies Discovery Sites, Nights in the (National) Parks, Sidewalk Astronomy) 3. Organize events in the arts (e.g., a photography contest) 4. Involve citizen-scientists in naked-eye and digital-meter star hunting programs (e.g., GLOBE at Night, "How Many Stars?", the Great World Wide Star Count and the radio frequency interference equivalent: "Quiet Skies") and 5. Raise awareness about the link between light pollution and public health, economic issues, ecological consequences, energy conservation, safety and security, and astronomy (e.g., The Starlight Initiative, World Night in Defense of Starlight, International Dark Sky Week, International Dark-Sky Communities, Earth Hour, The Great Switch Out, a traveling exhibit, downloadable posters and brochures). The presentation will provide an update, describe how people can become involved and take a look ahead at the program's sustainability. For more information, visit www.darkskiesawareness.org.

  3. Programming models for energy-aware systems

    Science.gov (United States)

    Zhu, Haitao

    Energy efficiency is an important goal of modern computing, with direct impact on system operational cost, reliability, usability and environmental sustainability. This dissertation describes the design and implementation of two innovative programming languages for constructing energy-aware systems. First, it introduces ET, a strongly typed programming language to promote and facilitate energy-aware programming, with a novel type system design called Energy Types. Energy Types is built upon a key insight into today's energy-efficient systems and applications: despite the popular perception that energy and power can only be described in joules and watts, real-world energy management is often based on discrete phases and modes, which in turn can be reasoned about by type systems very effectively. A phase characterizes a distinct pattern of program workload, and a mode represents an energy state the program is expected to execute in. Energy Types is designed to reason about energy phases and energy modes, bringing programmers into the optimization of energy management. Second, the dissertation develops Eco, an energy-aware programming language centering around sustainability. A sustainable program built from Eco is able to adaptively adjusts its own behaviors to stay on a given energy budget, avoiding both deficit that would lead to battery drain or CPU overheating, and surplus that could have been used to improve the quality of the program output. Sustainability is viewed as a form of supply and demand matching, and a sustainable program consistently maintains the equilibrium between supply and demand. ET is implemented as a prototyped compiler for smartphone programming on Android, and Eco is implemented as a minimal extension to Java. Programming practices and benchmarking experiments in these two new languages showed that ET can lead to significant energy savings for Android Apps and Eco can efficiently promote battery awareness and temperature awareness in real

    Results of monitoring of awareness level in dispensary patients with arterial hypertension (AH) are given in the article. The objective of the study was to investigate awareness level of dispensary patients with hypertension in Sumy as for the course of their disease, implementation of preventive measures, diagnosis and treatment, and to use the obtained information in the process of management of healthcare quality. The results of close-ended questionnaires were used in the capacity of materials. A total of 2019 patients were surveyed. Despite the high level of patients' awareness of AH course and possible complications, the survey showed insufficient level of their own responsibility for their health. The main reasons for poor adherence to doctor's recommendations are forgetfulness, lack of time, reluctance. Measures were developed to increase awareness level in patients with AH by means of strengthening awareness-raising activities and communications, as well as creation and implementation of effective targeted health-and-social programs.

    2015-01-01

    The Barilla Center for Food and Nutrition has produced an updated version of the traditional food pyramid based on the Mediterranean diet in order to assess the simultaneous impact that food has on human health and the environment. The Double Pyramid Model demonstrates how the foods recommended to be consumed most frequently are also those exerting less environmental impact, whereas the foods that should be consumed less frequently are those characterized by a higher environmental impact. The environmental impacts resulting from three different menus were compared. All menus were equally balanced and comparable in terms of nutrition, but they differed in relation to the presence of absence of animal flesh and animal products. The first dietary pattern (omnivorous) included both animal flesh and products; the second (lacto-ovo-vegetarian) included animal products (eggs and dairy) but no flesh; and the third (vegan) was solely plant-based. The results obtained suggest that a diet based on the principles of the Mediterranean diet, as suggested by the Double Pyramid, generates a lower environmental impact compared to diets that are heavily based on daily meat consumption.

    The Barilla Center for Food and Nutrition has produced an updated version of the traditional food pyramid based on the Mediterranean diet in order to assess the simultaneous impact that food has on human health and the environment. The Double Pyramid Model demonstrates how the foods recommended to be consumed most frequently are also those exerting less environmental impact, whereas the foods that should be consumed less frequently are those characterized by a higher environmental impact. The environmental impacts resulting from three different menus were compared. All menus were equally balanced and comparable in terms of nutrition, but they differed in relation to the presence of absence of animal flesh and animal products. The first dietary pattern (omnivorous) included both animal flesh and products; the second (lacto-ovo-vegetarian) included animal products (eggs and dairy) but no flesh; and the third (vegan) was solely plant-based. The results obtained suggest that a diet based on the principles of the Mediterranean diet, as suggested by the Double Pyramid, generates a lower environmental impact compared to diets that are heavily based on daily meat consumption.

    Research on implicit attitudes has raised questions about how well people know their own attitudes. Most research on this question has focused on the correspondence between measures of implicit attitudes and measures of explicit attitudes, with low correspondence interpreted as showing that people have little awareness of their implicit attitudes. We took a different approach and directly asked participants to predict their results on upcoming IAT measures of implicit attitudes toward five different social groups. We found that participants were surprisingly accurate in their predictions. Across four studies, predictions were accurate regardless of whether implicit attitudes were described as true attitudes or culturally learned associations (Studies 1 and 2), regardless of whether predictions were made as specific response patterns (Study 1) or as conceptual responses (Studies 2–4), and regardless of how much experience or explanation participants received before making their predictions (Study 4). Study 3 further suggested that participants’ predictions reflected unique insight into their own implicit responses, beyond intuitions about how people in general might respond. Prediction accuracy occurred despite generally low correspondence between implicit and explicit measures of attitudes, as found in prior research. All together, the research findings cast doubt on the belief that attitudes or evaluations measured by the IAT necessarily reflect unconscious attitudes. PMID:24294868

    There are insufficient data in the United States regarding patient awareness and expectations of hospital pharmacist availability and services. The objective of this research is to assess patient awareness and expectations of hospital pharmacist services and to determine whether a marketing campaign for pharmacist services increases patient awareness and expectations. Eligible inpatients were surveyed before and after implementation of a hospital-wide pharmacist services marketing campaign (12 items; Likert scale of 1 [strongly disagree] to 4 [strongly agree]; maximum total score of 48) regarding awareness of pharmacist services. The primary outcome was the change in median total survey scores from baseline. Other outcomes included the frequency of patient requests for pharmacists. Similar numbers of patients completed the survey before and after the campaign (intervention, n = 140, vs control, n = 147). Awareness of pharmacist availability and services was increased (41 [interquartile ranges, IQRs: 36-46] vs 37 [IQR 31-43]; P marketing campaign implementation. Awareness among inpatients of pharmacist services is low. Marketing pharmacist availability and services to patients in the hospital improves awareness and expectations for pharmacist-provided care and increases the frequency of patient-initiated interaction between pharmacists and patients. This could improve patient outcomes as pharmacists become more integrally involved in direct patient care.

    The purpose of the Pollution Prevention Awareness Program (PPAP), which is required by DOE Order 5400.1, is to foster the philosophy that prevention is superior to remediation. The goal of the program is to incorporate pollution prevention into the decision-making process at every level throughout the organization. The objectives are to instill awareness, disseminate information, provide training and rewards for identifying the true source or cause of wastes, and encourage employee participation in solving environmental issues and preventing pollution. PPAP at the Oak Ridge Y-12 Plant was created several years ago and continues to grow. We believe that we have implemented several unique methods of communicating environmental awareness to promote a more active work force in identifying ways of reducing pollution.

  6. Attention without awareness: Attentional modulation of perceptual grouping without awareness.

    Perceptual grouping is the process through which the perceptual system combines local stimuli into a more global perceptual unit. Previous studies have shown attention to be a modulatory factor for perceptual grouping. However, these studies mainly used explicit measurements, and, thus, whether attention can modulate perceptual grouping without awareness is still relatively unexplored. To clarify the relationship between attention and perceptual grouping, the present study aims to explore how attention interacts with perceptual grouping without awareness. The task was to judge the relative lengths of two centrally presented horizontal bars while a railway-shaped pattern defined by color similarity was presented in the background. Although the observers were unaware of the railway-shaped pattern, their line-length judgment was biased by that pattern, which induced a Ponzo illusion, indicating grouping without awareness. More importantly, an attentional modulatory effect without awareness was manifested as evident by the observer's performance being more often biased when the railway-shaped pattern was formed by an attended color than when it was formed by an unattended one. Also, the attentional modulation effect was shown to be dynamic, being more pronounced with a short presentation time than a longer one. The results of the present study not only clarify the relationship between attention and perceptual grouping but also further contribute to our understanding of attention and awareness by corroborating the dissociation between attention and awareness.

  7. Energy-Aware Cognitive Radio Systems

    KAUST Repository

    Bedeer, Ebrahim

    2016-01-15

    The concept of energy-aware communications has spurred the interest of the research community in the most recent years due to various environmental and economical reasons. It becomes indispensable for wireless communication systems to shift their resource allocation problems from optimizing traditional metrics, such as throughput and latency, to an environmental-friendly energy metric. Although cognitive radio systems introduce spectrum efficient usage techniques, they employ new complex technologies for spectrum sensing and sharing that consume extra energy to compensate for overhead and feedback costs. Considering an adequate energy efficiency metric—that takes into account the transmit power consumption, circuitry power, and signaling overhead—is of momentous importance such that optimal resource allocations in cognitive radio systems reduce the energy consumption. A literature survey of recent energy-efficient based resource allocations schemes is presented for cognitive radio systems. The energy efficiency performances of these schemes are analyzed and evaluated under power budget, co-channel and adjacent-channel interferences, channel estimation errors, quality-of-service, and/or fairness constraints. Finally, the opportunities and challenges of energy-aware design for cognitive radio systems are discussed.

    A new vapor generation system for mercury (Hg) species based on the irradiation of mercaptoethanol (ME) with UV was developed to provide an effective sample introduction unit for atomic fluorescence spectrometry (AFS). Preliminary investigations of the mechanism of this novel vapor generation system were based on GC-MS and FT-IR studies. Under optimum conditions, the limits of determination for inorganic divalence mercury and methyl mercury were 60 and 50 pg mL{sup -1}, respectively. Certified reference materials (BCR 463 tuna fish and BCR 580 estuarine sediment) were used to validate this new method, and the results agreed well with certified values. This new system provides an attractive alternative method of chemical vapor generation (CVG) of mercury species compared to other developed CVG systems (for example, the traditional KBH{sub 4}/NaOH-acid system). To our knowledge, this is the first systematic report on UV/ME-based Hg species vapor generation and the determination of total and methyl Hg in environmental and biological samples using UV/ME-AFS.

    To identify correlates of beer advertising awareness among adolescents at an age when most initiate use of alcohol. We conducted a cross-sectional analysis of an in-school survey about alcohol advertising. Structural equation modeling was used to test for independent predictors of a latent beer advertising awareness construct, separately among boys and girls. Twenty middle schools in South Dakota, USA participated during their spring semester. A total of 1530 eighth graders. A latent advertisement awareness variable was derived based on recognition of six masked beer advertisements, knowledge of beer brands and knowledge of beer slogans. Tested predictors included measures of exposure to alcohol advertising in various venues, social norms regarding drinking, drinking beliefs and behavior and gender. Adolescents with greater exposure to advertisements in magazines, at sporting and music events and on television were more advertisement aware than those with less exposure, as were teens who watch more TV, pay attention to beer advertisements and know adults who drink. Beer advertisement awareness was dramatically higher among boys, and was associated with drinking only among boys. Each of a variety of advertising venues appears to influence independently the extent to which beer advertising is incorporated into an adolescent's cognitive world. Boys are more likely to be aware of and remember beer marketing, and may be more likely to drink as a result of this awareness than girls.

  19. Competing spreading processes on multiplex networks: awareness and epidemics.

    Granell, Clara; Gómez, Sergio; Arenas, Alex

    2014-07-01

    Epidemiclike spreading processes on top of multilayered interconnected complex networks reveal a rich phase diagram of intertwined competition effects. A recent study by the authors [C. Granell et al., Phys. Rev. Lett. 111, 128701 (2013).] presented an analysis of the interrelation between two processes accounting for the spreading of an epidemic, and the spreading of information awareness to prevent infection, on top of multiplex networks. The results in the case in which awareness implies total immunization to the disease revealed the existence of a metacritical point at which the critical onset of the epidemics starts, depending on completion of the awareness process. Here we present a full analysis of these critical properties in the more general scenario where the awareness spreading does not imply total immunization, and where infection does not imply immediate awareness of it. We find the critical relation between the two competing processes for a wide spectrum of parameters representing the interaction between them. We also analyze the consequences of a massive broadcast of awareness (mass media) on the final outcome of the epidemic incidence. Importantly enough, the mass media make the metacritical point disappear. The results reveal that the main finding, i.e., existence of a metacritical point, is rooted in the competition principle and holds for a large set of scenarios.

    2015-02-01

    The unprecedented rise of mobile user demand over the years have led to an enormous growth of the energy consumption of wireless networks as well as the greenhouse gas emissions which are estimated currently to be around 70 million tons per year. This significant growth of energy consumption impels network companies to pay huge bills which represent around half of their operating expenditures. Therefore, many service providers, including mobile operators, are looking for new and modern green solutions to help reduce their expenses as well as the level of their CO2 emissions. Base stations are the most power greedy element in cellular networks: they drain around 80% of the total network energy consumption even during low traffic periods. Thus, there is a growing need to develop more energy-efficient techniques to enhance the green performance of future 4G/5G cellular networks. Due to the problem of traffic load fluctuations in cellular networks during different periods of the day and between different areas (shopping or business districts and residential areas), the base station sleeping strategy has been one of the main popular research topics in green communications. In this presentation, we present several practical green techniques that provide significant gains for mobile operators. Indeed, combined with the base station sleeping strategy, these techniques achieve not only a minimization of the fossil fuel consumption but also an enhancement of mobile operator profits. We start with an optimized cell planning method that considers varying spatial and temporal user densities. We then use the optimal transport theory in order to define the cell boundaries such that the network total transmit power is reduced. Afterwards, we exploit the features of the modern electrical grid, the smart grid, as a new tool of power management for cellular networks and we optimize the energy procurement from multiple energy retailers characterized by different prices and pollutant

    BACKGROUND: Patients\\' awareness of the increased cardiovascular risk associated with their diabetes is poorly documented. AIM: The aim of this study was to assess the awareness of diabetes complications among patients with diabetes in Ireland. METHODS: Patients attending diabetes outpatient clinics in two teaching hospitals in different regions of the country were invited to complete a questionnaire. RESULTS: A total of 258 (59.3% male) patients completed the questionnaire; mean age 57.8 years. On questioning, 53.5% reported cardiovascular disease as a potential complication of diabetes, with awareness rates of 61.2, 17.1, 16.3 and 12% for retinopathy, stroke, peripheral vascular disease and amputation, respectively. Disappointingly, less than half of respondents felt that improvements in diet and exercise could potentially reduce their cardiovascular risk. CONCLUSIONS: Awareness of cardiovascular risk and knowledge of effective measures to reduce this were low in our study and an alternative means of education may need to be considered.

  6. 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.

The program was held under The Urban Disaster Risk Reduction Greater Jakarta Project; an initiative program from American Red Cross Indonesia. This project was not only improving the existing green open space quality, but also creating one adapted from public land. The revitalization project figures what happened on daily basis on the existing land, proposing new programming facilities, community-based construction, monitoring and handing over. This paper discovers the meaning of a green space for the community, whether the community aware of its benefit on human health or environmental sustainability. The research question is does the community aware of green open space benefit for human health or environmental sustainability? Or both? The original data from the community was gathered and grouped based on its relevance with environmental quality and public health.

    Full Text Available Aim: To assess the awareness and knowledge levels about glaucoma and its determinants in an urban population of Chennai in south India. Materials and Methods: Chennai glaucoma study (CGS was a population based prevalence study to estimate the prevalence of glaucoma in a rural and urban south Indian population. A total of 3850 subjects aged 40 years or above participated in the urban arm of CGS. A systematic random sample of 1926 (50.0% subjects completed a questionnaire that assesses their awareness and knowledge level of glaucoma. Respondents "having heard of glaucoma" even before they were contacted/recruited for the study were defined as "aware" and respondents having some understanding of the eye disease were defined as "knowledgeable". Results: Overall 13.5% were aware of glaucoma, the age-gender adjusted rate for awareness was 13.3% (95% CI: 11.57 to 15.03. Two clinicians graded knowledge on glaucoma, based on the subject′s knowledge of risk factors, definitions and treatment aspects of glaucoma. Overall 8.7% had some knowledge about glaucoma. Among those who had knowledge 0.5% had good knowledge about glaucoma, 4% had fair knowledge and 4.2% had poor knowledge. We observed a very good agreement between the clinicians in grading knowledge (k =0.92. Determinants of glaucoma awareness and knowledge were higher levels of education, females, age, religion and family history of glaucoma. Conclusion: Awareness and knowledge about glaucoma was very low among the urban population of Chennai. We have found that younger subjects and men were less aware of glaucoma. Subjects with lower levels of education were less aware and knew less about glaucoma than their counterparts. The study findings stress the need for health education for effective prevention of blindness due to glaucoma.

    The main objective of this study was to review the evidence relating to the level of awareness of human papillomavirus (HPV) in the general population and the implications for the potential introduction of HPV vaccination and HPV testing as part of screening. PubMed search performed on terms: 'HPV education', 'HPV awareness' 'Genital Warts Awareness' Results: Public awareness of HPV is generally very low, particularly with respect to its relation to abnormal smears and cervical cancer although knowledge levels vary to some extent according to sociodemographic characteristics. There is also much confusion around which types cause warts and the types that can cause cancer. The sexually transmissible nature of the infection is of major concern and confusion to women. Due to the lack of current awareness of HPV, significant education initiatives will be necessary should HPV vaccination and/or HPV testing be introduced. Organized edification of health-care workers and the media, who constitute the two most preferred sources of information, will be crucial.

    Awareness of the status of disease among terminally ill cancer patients is an important part of the end-of-life care. We have evaluated how palliative care consultative service (PCCS) affects patient disease awareness and determined who may benefit from such services in Taiwan. In total, 2,887 terminally ill cancer patients consecutively received PCCS between January 2006 and December 2010 at a single medical center in Taiwan, after which they were evaluated for disease awareness. At the beginning of PCCS, 31 % of patients (n = 895) were unaware of their disease status. The characteristics of these 895 patients were analyzed retrospectively to determine variables pertinent to patient disease awareness after PCCS. In total, 485 (50 %) of the 895 patients became aware of their disease at the end of PCCS. Factors significantly associated with higher disease awareness included a longer interval between the date of hospital admission and that of PCCS referral (>4 weeks versus ≤2 weeks), a longer duration of PCCS (>14 days versus ≤7 days), the male gender, divorced marital status (versus married), and family awareness (versus lack of family awareness). Lower disease awareness was associated with older age (age > 75 years versus age = 18-65 years), referral from non-oncology departments, and primary cancer localization (lung, colon-rectum, or urological versus liver). Disease awareness is affected by multiple factors related to the patients, their families, and the clinicians. The promotion of PCCS increased disease awareness among terminally ill cancer patients in Taiwan.

    Full Text Available The context refers to “any information that can be used to characterize the situation of an entity, where an entity can be a person, place, or physical object.” Radio context awareness is defined as the ability of detecting and estimating a system state or parameter, either globally or concerning one of its components, in a radio system for enhancing performance at the physical, network, or application layers. In this paper, we review the fundamentals of context awareness and the recent advances in the main radio techniques that increase the context awareness and smartness, posing challenges and renewed opportunities to added-value applications in the context of the next generation of wireless networks.

    We study a susceptible-infected-susceptible epidemic process over a static contact network where the nodes have partial information about the epidemic state. They react by limiting their interactions with their neighbors when they believe the epidemic is currently prevalent. A node\\'s awareness is weighted by the fraction of infected neighbors in their social network, and a global broadcast of the fraction of infected nodes in the entire network. The dynamics of the benchmark (no awareness) and awareness models are described by discrete-time Markov chains, from which mean-field approximations (MFAs) are derived. The states of the MFA are interpreted as the nodes\\' probabilities of being infected. We show a sufficient condition for the existence of a

    Breast cancer is the most common female cancer worldwide including India, where advanced stages at diagnosis, and rising incidence and mortality rates, make it essential to understand cancer literacy in women. We conducted a literature review to evaluate the awareness levels of risk factors for breast cancer among Indian women and health professionals. A structured literature search using combined keywords was undertaken on bibliographic databases including MEDLINE, Cochrane Database of Systematic Reviews, Cumulative Index to Nursing and Allied Health (CINAHL) and SCOPUS. Searches were restricted to research published in English language peer-reviewed journals through December, 2014 in India. A total of 7066 women aged 15-70 years showed varied levels of awareness on risk factors such as family history (13-58%), reproductive history (1-88%) and obesity (11-51%). Literacy levels on risk factors did not improve over the 8-year period (2005-2013). On average, nurses reported higher, though still varied, awareness levels for risk factors such as family history (40.8-98%), reproductive history (21-90%) and obesity (34-6%). Awareness levels were not consistently higher for the stronger determinants of risk. Our review revealed low cancer literacy of breast cancer risk factors among Indian women, irrespective of their socio-economic and educational background. There is an urgent need for nation- and state-wide awareness programmes, engaging multiple stakeholders of society and the health system, to help improve cancer literacy in India.

    Full Text Available Green environmental issues have been of topical interest to both researchers and industrialists for some time now. Research on green brands is relatively limited, especially in developing countries, such as Ghana. This study is therefore designed to determine the relationship between customer awareness of green brand issues and their everyday purchase intentions. Using quantitative techniques, the study interviewed 316 people, conveniently selected from various shopping points in Accra. The study found that, the overwhelming majority of respondents though familiar with green issues did not concern themselves with green issues in their everyday purchase decisions. Again, majority of respondents (54% familiar with environmental issues confirmed they would not switch from their preferred brands to less fancied brands even if the less fancied brands were more environmentally friendly. It was also confirmed in the study that price, brand name and convenience, performed better than customer concerns for green issues, in influencing respondents’ purchase decisions. It would therefore be strategically significance if advocates, policy makers and business leaders reduce the cost of green products to the final consumer, intensive public education campaigns, coupled with strategic brand building efforts to enhance the level of green brand consumption.

    This paper addresses the questions ''Do people think about the environment in similar ways.'', ''What are the similarities and differences across different groups within a country, and what are the similarities and differences across countries.'' Using a new factor-analytical approach (which is described in detail in the appendix) four independent cognitive dimensions of the ecological awareness could be found from a set of 12 Items of the International Environmental Survey of 1980: 1. Attitude toward science and technology; 2. Concern about resources and energy supply; 3. Attitude toward nuclear power; 4. Concern about the limits to growth. The major similarities overall and the minor differences between the countries will be discussed. (orig.) [de

    Full Text Available The basic purpose of this study has been to examine the relationships between metacognitive awareness and maths anxiety in gifted students. The second aim was to compare with gifted and non-gifted students’ metacognitive awareness and maths anxiety levels. The participants were 300 (150 gifted, 150 non-gifted volunteer secondary school students in Turkey. The mean age of the participants was 12.56 years ranging from 12 to 13 years. For gathering data, the Maths Anxiety Scale for Elementary School Students and The Metacognitive Awareness Inventory for Children were used. For analysing the data, Spearman correlation analysis, the Mann Whitney U test, and linear regression analysis were used. According to the findings: firstly, gifted students’ metacognitive awareness scores were higher than those of non-gifted students. On the other hand, non-gifted students’ maths anxiety levels were higher than those of gifted students. Secondly, there was negative correlation between metacognitive awareness and math anxiety. Finally, the findings of linear regression analysis indicated that metacognitive awareness is explained by 48% total variance of maths anxiety in gifted students.

    2012-01-01

    The high breast cancer mortality rate in Sub-Saharan Africa has been attributed to a lack of public awareness of the disease which often leads to late diagnosis of the disease. Little is known about the level of knowledge and awareness of breast cancer in Angola. Previous studies have shown that breast cancer awareness is higher among well-educated people. The goal of this study was to assess breast cancer knowledge and awareness among university students in Angola. We conducted a cross-sectional survey of university students using a self-administered questionnaire to investigate participants' awareness and knowledge of breast cancer. A total of 595 university students in medical and non-medical programs successfully completed the survey. Our results showed insufficient knowledge of breast cancer among university students in Angola irrespective of whether they were in medical or non-medical programs. The majority of the participants were not aware of some of the early signs of breast cancer such as change in color or shape of the nipple, even though they appreciated the need for monthly breast self-examination. Overall most of the participants indicated the need for increased breast cancer awareness among university students. The study points to the insufficient knowledge of university students in Angola about breast cancer. We expect that our results may provide useful data that may be used by the department of health in Angola and other African countries to formulate health education programs aimed at increasing awareness and promote screening and early detection of breast cancer in the continent.

    Filipino Americans have high rates of hypertension, yet little research has examined hypertension awareness, treatment, and control in this group. In a community-based sample of hypertensive Filipino American immigrants, we identify 1) rates of hypertension awareness, treatment, and control; and 2) factors associated with awareness, treatment, and control. Cross-sectional analysis of survey data from health screenings collected from 2006 to 2010. A total of 566 hypertensive Filipino immigrants in New York City, New York and Jersey City, New Jersey. Hypertension awareness, treatment, and control. Participants were included in analysis if they were hypertensive, based on: a past physician diagnosis, antihypertensive medication use, and/or high blood pressure (BP) screening measurements. Demographic variables included sex, age, time in the United States, location of residence, and English spoken language fluency. Health-related variables included self-reported health, insurance status, diabetes diagnosis, high cholesterol diagnosis, clinical measures (body mass index [BMI], glucose, and cholesterol), exercise frequency, smoking status, cardiac event history, family history of cardiac event, and family history of hypertension. Among the hypertensive individuals, awareness, treatment, and control rates were suboptimal; 72.1 % were aware of their status, 56.5 % were on medication, and only 21.7 % had controlled BP. Factors related to awareness included older age, worse self-reported health, family history of hypertension, and a diagnosis of high cholesterol or diabetes; factors related to treatment included older age, longer time lived in the United States, and being a non-smoker; having health insurance was found to be the main predictor of hypertension control. Many individuals had other cardiovascular disease (CVD) risk factors; 60.4 % had a BMI ≥25, 12.0 % had at-risk glucose measurements and 12.8 % had cholesterol ≥ 240. Hypertensive Filipinos exhibit poor

    Today, environmental policy has to face economic considerations more than in former times. By means of an economic valuation of environmental damage, it is possible to estimate the economic utility of environmental policy measures. This is important because today's environmental policy prevents tomorrow's environmental damage. At present, there is no other field where this fact has become as obvious as in climate policy. All recent publications have provided evidence that climate protection is worthwhile because the costs of climate protection measures are lower than those resulting from inactivity. Economic valuation means to weigh a number of choices and targets against each other. Valuation requires value judgements. How to define a damage event? How to weigh different goods which deserve protection against each other and damage occurring today against that occurring in the future? How to deal with uncertainty with regard to future returns and risks? These are only a few of the problems depending on value judgements that we have to face. This applies in general and not only in economic valuation. The Methodological Convention elaborated by the Federal Environment Agency addresses these problems. It has been the intention of the authors to explain and substantiate their value judgements and the criteria underlying the valuation of environmental damage (as well as that of environmental damage that has been avoided). Thus, the Federal Environment Agency wishes to make a contribution to transparency and consistency of decision-making in environmental policy. The principles of valuation suggested may be used for example to substantiate cost rates for external costs incurred by energy production and transport. The exemplary calculations have demonstrated that the internalization of environmental costs has been achieved in part only. Policy makers may choose different ways to gradually improve this situation. Internalization does not necessarily mean that

    Full Text Available Environment as the totality of natural and man-made values and their relationships, is a complex problem that is not just a challenge for the law in the sense that it is protected from intrusion, but also for the negative social phenomena such as crime. Dynamic negative social phenomenon, immanent to every society, crime is constantly in the process of 'adaptation' in terms of modification of existing and creation of new forms. One of the contemporary forms of crime is an environmental crime which multiplies its concrete forms of manifestation, which is due to the extraordinary diversity of the environment in which offenders constantly find new enforcement cases. Especially significant issues regarding the environment is waste whose collection, transport, treatment and disposal is one of the priority importance for humanity. However, insufficient awareness of the significance and importance of this issue, as well as the harmful consequences of failure in connection with the waste in an appropriate manner, together with the motive of greed is enough for offenders to deal with illegal activity and exercise in relation to different types of waste. In this type of criminal activity usually occur organized criminal group that this type of criminal activity makes it even more difficult. These problems are extremely important and complex, in this paper, attention is given to the organized environmental crime in connection with smuggling of hazardous waste, as one of the forms of organized environmental crime.

  16. The Central Neural Foundations of Awareness and Self-Awareness

    Science.gov (United States)

    Pfaff, D.; Martin, E. M.; Weingarten, W.; Vimal, V.

    In the past, neuroscientists have done very well to concentrate onexplaining the mechanisms for very specific, simple behaviors. For example, our laboratory's work with molecular and neural mechanisms of a simple sex behavior proved for the first time that specific biochemical reactions in specific parts of the brain govern a specific behavior [D. W. Pfaff, Drive: Neurobiological and Molecular Mechanisms of Sexual Motivation (The MIT Press, Cambridge, 1999)]. Now, advances in our field coupled with new techniques permit us to attack the problems of explaining global changes of state in the central nervous system. For example, how does a simple sex behavior depend on sexual arousal, and in turn, how does that sexual arousal depend on other forms of CNS arousal? Of surpassing interest is the explanation of the primary causes of brain arousal [D. W. Pfaff, textit{Brain Arousal and Information Theory: Neural and Genetic Mechanisms} (Harvard University Press, Cambridg e, 2006)]. We have hypothesized that the earliest and most elementary event in waking up the brain is the activation of certain primitive nerve cells in the hindbrain reticular formation. Hypothesizing a `generalized arousal' force emanating from these cells puts forth an idea roughly analogous to the hypothesis of a `big bang' in astrophysics, or to our ideas about the magma of the earth in geophysics. Following the activation of this primitive arousal force we are able to be alert and aware. The neuroanatomical pathways serving brain arousal are fairly well known: they are Bilateral, Bidirectional, Universal among vertebrate animals including humans, and they are always involved in Response Potentiation, approach or avoidance responses (BBURP theory). More than 120 genes are involved in the regulation of brain arousal. In theoretical terms, the discussion so far has dealt with `bottoms up' approaches to awareness -- from mechanisms in the hindbrain working through several phylogenetically ancient

    2008-07-01

    Attention to internal body sensations is practiced in most meditation traditions. Many traditions state that this practice results in increased awareness of internal body sensations, but scientific studies evaluating this claim are lacking. We predicted that experienced meditators would display performance superior to that of nonmeditators on heartbeat detection, a standard noninvasive measure of resting interoceptive awareness. We compared two groups of meditators (Tibetan Buddhist and Kundalini) to an age- and body mass index-matched group of nonmeditators. Contrary to our prediction, we found no evidence that meditators were superior to nonmeditators in the heartbeat detection task, across several sessions and respiratory modulation conditions. Compared to nonmeditators, however, meditators consistently rated their interoceptive performance as superior and the difficulty of the task as easier. These results provide evidence against the notion that practicing attention to internal body sensations, a core feature of meditation, enhances the ability to sense the heartbeat at rest.

    Dyscalculia is a learning need that requires assessment and provision of reasonable adjustments. Although there have been numerous discussions about how to identify, assess and support dyscalculic children, there is less information available covering further and higher education, and even less concerned with the education of health professionals. This article aims to address this deficit, to discuss the disparity often felt by educators, and to raise awareness of the impact of dyscalculia on student nurses.

  2. Harvesting-Aware Energy Management for Environmental Monitoring WSN

    James Rodway

    2017-05-01

    Full Text Available Wireless sensor networks can be used to collect data in remote locations, especially when energy harvesting is used to extend the lifetime of individual nodes. However, in order to use the collected energy most effectively, its consumption must be managed. In this work, forecasts of diurnal solar energies were made based on measurements of atmospheric pressure. These forecasts were used as part of an adaptive duty cycling scheme for node level energy management. This management was realized with a fuzzy logic controller that has been tuned using differential evolution. Controllers were created using one and two days of energy forecasts, then simulated in software. These controllers outperformed a human-created reference controller by taking more measurements while using less reserve energy during the simulated period. The energy forecasts were comparable to other available methods, while the method of tuning the fuzzy controller improved overall node performance. The combination of the two is a promising method of energy management.

    School Children are the torchbearers of information, development and awareness in the country. They are the custodians of the future, thus it is important to educate them on this sensitive issue for a secured future for them. They are not rigid in their thoughts and are open to ideas and willing to listen, which gives us an opportunity to sensitize them about the growing issues that will shape their future So my projects with students every year revolves around an impactful contribution in reaching out and building awareness about preserving the environment and incorporating the practices of reuse, reduce and recycle in our daily lives. Under this project I conduct various workshops on recycling waste, debates on the environmental challenges with regular focus on inculcating cleaner habits amongst children ensuring an attitude change which will help create a socially responsible society. The community is enlightened on the importance of being responsible towards own household waste and conservation of the planet by conducting workshops across various residential societies in Pune. The idea is to encourage the young students and teachers to practice the 4Rs - Refuse, Reuse, Reduce and Recycle - in our daily lives. Through workshops, film screening, simulation exercises, competitions and students exchange programs the children are sensitized about waste management and importance of recycling to make them aware of the need to 'Protect What's Good' - which is the environment.

    Making quick and effective decisions in environment management are based on multiple and complex parameters, a data warehouse is a powerful tool for the over all management of massive environmental information. Selecting the right data from a warehouse is an important factor consideration for end-users. This paper proposed an intelligent environmental data warehouse system. It consists of data warehouse to feed an environmental researchers and managers with desire environmental information needs to their research studies and decision in form of geometric and attribute data for study area, and a metadata for the other sources of environmental information. In addition, the proposed intelligent search engine works according to a set of rule, which enables the system to be aware of the environmental data wanted by the end-user. The system development process passes through four stages. These are data preparation, warehouse development, intelligent engine development and internet platform system development. (author)

    Full Text Available Background: General anesthesia is a reversible state of a temporary loss of consciousness, analgesia, muscle paralysis, blunted autonomic responses and amnesia. To achieve this, an adequate depth of anesthesia should be maintained throughout the surgery. Awareness is a serious complication of general anesthesia, which occurs when the depth of anesthesia is not appropriate due to various causes.In this paper the underlying neurobiology of intraoperative awareness is presented, as well as risk factors for awareness and methods for assessing the depth of anesthesia. Possible psychological consequences of awareness and their management are also discussed. At the end, the recommendations for preventing intraoperative awareness are given.Conclusions: Awareness during general anesthesia may have adverse psychological sequelae in individual patients, therefore guidelines for preventing and managing of intraoperative awareness need to be adopted. In case of a possible awareness, the recommendations for offering a psychological support should also be followed.

  11. Measures to reinforce the legal liability of the environmental interest subject —Based on the perspective of law and economics

    Science.gov (United States)

    Fa, L. N.

    2017-11-01

    Local government should be regarded as the main subject to be stipulated by environmental law, thus to avoid local government’s alignment with commercial interests. Such a shift would, furthermore, discourage collusion against environment law or speculative behaviors motivated by maximizing production at the expense of environment pollution. Moreover, whether companies make proactive decisions to prevent pollution or not depends on the severity of appropriate environment legal system’s sanctions for their action. It would encourage enterprises to undertake their own environmental responsibility if environmental law could further enhance their environmental liability. In addition, public environmental rights should be embedded into environmental law. In this way, the public may become more aware of their environmental rights as well as the positivity of total environmental interests.

Çalışmanın verileri Gıda, Tarım ve Hayvancılık Bakanlığı Iğdır İl Müdürlüğünün Çiftçi Kayıt Sisteminde kayıtlı toplam 104 tarım işletmesinin sahipleriyle yüz yüze yapılan anket çalışmalarıyla elde edilmiştir. Tarım ilâçlarının çevreye zararı konusunda çiftçilerin yarısına yakın kısmının zarar yoktur demesi, dörtte birinin de kalıntılar konusunda zararsız olacağını ifade etmesi çiftçinin bilinç seviyesinde yetersizliği ifade etmektedir. Bilhassa ilâçlama âletlerinin temizleme sularının atılmasında yeterli dikkatin gösterilmemesi, ilâç ambalajları ile kalan ilâçların muhafaza ve imhasındaki cevaplar çiftçilerin hem çevre hem de ziraî mücadele konusunda ki bilinçsizliğini göstermektedir. Environmental Awareness of Agricultural Enterprises in the Igdir Province of Turkey at Implementation of Plant Protection In this study, it was researched if farmers from the Igdir Province of Turkey have knowledge and awareness on effect of plant protection implementations on environment and human health. The data were collected from 104 enterprises, which have been recorded in Farmer Records System of the Igdir Province directorate of Food, Agriculture and Livestock Ministry, through discussions face to face. Almost half of the farmers told that pesticides are harmless, and one forth that pesticide residues are harmless, which shows insufficiency in conciseness of farmers. Especially, that no attention was given cleaning water’ deposits, removing empty chemical’s packages, and storing remaining pesticides, showed lack of awareness on plant protection and environment.

    Full Text Available Abstract Background Awareness of the danger signs of obstetric complications is the essential first step in accepting appropriate and timely referral to obstetric and newborn care. The objectives of this study were to assess women's awareness of danger signs of obstetric complications and to identify associated factors in a rural district in Tanzania. Methods A total of 1118 women who had been pregnant in the past two years were interviewed. A list of medically recognized potentially life threatening obstetric signs was obtained from the responses given. Chi- square test was used to determine associations between categorical variables and multivariate logistic regression analysis was used to identify factors associated with awareness of obstetric danger signs. Results More than 98% of the women attended antenatal care at least once. Half of the women knew at least one obstetric danger sign. The percentage of women who knew at least one danger sign during pregnancy was 26%, during delivery 23% and after delivery 40%. Few women knew three or more danger signs. According to multivariate logistic regression analysis having secondary education or more increased the likelihood of awareness of obstetric danger signs six-fold (OR = 5.8; 95% CI: 1.8–19 in comparison with no education at all. The likelihood to have more awareness increased significantly by increasing age of the mother, number of deliveries, number of antenatal visits, whether the delivery took place at a health institution and whether the mother was informed of having a risks/complications during antenatal care. Conclusion Women had low awareness of danger signs of obstetric complications. We recommend the following in order to increase awareness of danger signs of obstetrical complications: to improve quality of counseling and involving other family members in antenatal and postnatal care, to use radio messages and educational sessions targeting the whole community and to intensify

This paper aimed to explore the level of awareness on HIV/AIDs among the women whose husbands stay apart from them for over a period of 6 months. For this cross sectional study, women attending public and private hospitals in Dhaka city were selected purposively. The participants were interviewed using a partially open-structured questionnaire. A total of 404 subjects were interviewed. Most of the respondents were housewives (85.7%. The higher education group had a high prevalence of awareness (>=HSC vs. SSC: 45.0% vs. 8.5%; p<0.001. The prevalence of awareness was significantly higher among the employed than the housewives (50% vs. 12.4%, p<0.001. Although the wives of the unskilled labor and the skilled employee were equal (25% vs. 25%, the wives of skilled employee had significantly higher awareness than the wives of the unskilled laborer (30.7 vs. 10.9%, p = 0.001. The study concludes that higher awareness level was significantly associated with higher education of the participants and higher education of the husband. Occupationally, housewives were found to have very low level of awareness compared with the employed group of participants. Again the wives of skilled employees had a significantly higher prevalence of awareness compared with the wives of unskilled laborer. Ibrahim Med. Coll. J. 2011; 5(1: 25-28

    Radiation, which is simply defined as energy, that travels in the form of waves or particles has both positive and negative effects on humans. This has necessitated a careful study on how to create awareness on the 'two-edge sword'. Since radiation cannot be removed from our environment we, however, reduce our risks by controlling our exposure to it through various ways. Understanding radiation and radioactivity will help us make informed decisions about our exposure. Many difference types of radiation have range of energy that form electromagnetic spectrum. Their sources include nuclear power plants, nuclear weapons, and medicine. Others include, microwaves, radar, electrical power lines, cellular phones, and sunlight' and so on. However, the radiation used in nuclear power, nuclear weapons, and medicine has enough energy to break chemical bonds, and is referred to as 'ionizing radiation', which is dangerous to life. Because of this negative effect of radiation there is common fear and myths related to radiation, radioactivity, uranium mining and milling, and the nuclear industry. This radiation education and energy-environmental education attempt to dispel the common fears and myths relating to them in so far as there is perfect protection from harmful exposure and abuse. The design of an integrated unit of study radiation and environmental energy uses arts of language, life skills, skill designs, social studies and mathematical skills in creating understanding and abilities necessary to do scientific inquiry by the students without abuse or danger. The education unit is designed to assess materials for, factual information and appropriate language and identification of potential bias in environmental education materials and evaluate materials in perspective of cultural and ethnic upbringing.

  19. The effect of awareness on networked SIS epidemics

    Paarporn, Keith

    2017-01-05

    We study an SIS epidemic model over an arbitrary fixed network topology where the n agents, or nodes of the network, have partial information about the epidemic state. The agents react by distancing themselves from their neighbors when they believe the epidemic is currently prevalent. An agent\\'s awareness is weighted from three sources of information: the fraction of infected neighbors in their contact network, their social network, and a global broadcast of the fraction of infected nodes in the entire network. The dynamics of the benchmark (no awareness) and awareness models are described by discrete-time 2-state Markov chains. Through a coupling technique, we establish monotonicity properties between the benchmark and awareness models. Particularly, we show that the expectation of any increasing random variable on the space of sample paths, e.g. eradication time or total infections, is lower for the awareness model. In addition, we give a characterization for this difference of expectations in terms of the coupling distribution. In simulations, we evaluate how different sources of information affect the spread of an epidemic.

    In the UK there has been an effort, through the National Awareness and Early Diagnosis Initiative (NAEDI), to increase early stage diagnoses and ultimately cancer survival. Encouraging early symptom presentation through awareness-raising activities in primary care is one method to achieve this goal. Understanding GPs' views about this type of activity, however, is crucial prior to implementation. To describe GPs' attitudes to raising public awareness of gynaecological cancers, and their views about the potential impact on primary care services. An online survey with a convenience sample recruited from 1860 UK general practices. An invitation was emailed to GPs via practice managers and included a weblink to a draft education leaflet and an online survey about the impact of sending a leaflet giving information about symptoms associated with gynaecological cancers to all women on GPs' lists. Participants could offer additional free text comments which were coded using content analysis. A total of 621 GPs participated. Most (77%, 477) felt that raising awareness of cancers was important. Only half (50%, 308), however, indicated that they would distribute such a leaflet from their practice. Barriers to implementation included concerns about financial costs; emotional impact on patients; increased demand for appointments and diagnostic services, such as ultrasound. GPs were generally positive about an intervention to improve patients' awareness of gynaecological cancers, but had concerns about increasing rates of presentation. There is a need for research quantifying the benefits of earlier diagnosis against resource costs such as increased consultations, investigations, and referrals. © British Journal of General Practice 2014.

    Full Text Available Blood transfusion is a life saving procedure in various transfusion-dependent life threatening conditions and donation of safe blood is a prerequisite for achieving this goal. This study was designed to evaluate the awareness regarding “safe blood” in Pakistani population. This study was conducted at a large scale through a population survey. The test population was divided into two groups i.e. general population and students. The Performa was designed for a general and student population and included 20 questions related to awareness of safe blood. A total of 4900 individuals belonging to different ethnic groups were included in this population survey. Results of social survey were analyzed by using Usman and Moin awareness chart. Results of this study revealed profound unawareness about safe blood in Pakistani population. This study found lack of awareness about safe blood as a major factor that is playing a vital role in the propagation of blood borne diseases in Pakistan. To secure the recipients from blood borne complications through blood donation, it is necessary to create effective awareness about safe blood in Pakistani population.

    To compare the awareness of provisions of consumer protection act among dental and medical professionals in Udaipur city, Rajasthan, India. In a cross sectional study, a total of 448 professionals (253 males, 195 females) belonging to dental (222) and medical (226) categories were surveyed using a self administered structured questionnaire. The questionnaire comprised of 22 questions about the awareness of consumer protection art (CPA) and whether these professionals were following the recommendations of CPA. The student's t-test, ANOVA test, and Scheffe's test were used as tests of significance. The awareness scores were significantly higher for medical professionals compared with those of dental professionals. Similarly, postgraduates showed more awareness in both the professions and it was found that private practitioners significantly have more awareness than the academic sector. Though medical professionals have more awareness of CPA compared to dental professionals, considering the present scenario, better knowledge of CPA is necessary for both professionals in order to be on the safer side.

    To make appropriate, timely decisions in the field, Situational Awareness (SA) needs to be conveyed in a decentralized manner to the users at the edge of the network as well as at operations centers. Sharing real-time SA efficiently between command centers and operational troops poses many challenges, including handling heterogeneous and dynamic networks, resource constraints, and varying needs for the collection, dissemination, and display of information, as well as recording that information. A mapping application that allows teams to share relevant geospatial information efficiently and to communicate effectively with one another and command centers has wide applicability to many vertical markets across the Department of Defense, as well as a wide variety of federal, state local, and non-profit agencies that need to share locations, text, photos, and video. This paper describes the Android Team Awareness Kit (ATAK), an advanced, distributed tool for commercial- off-the-shelf (COTS) mobile devices such as smartphones and tablets. ATAK provides a variety of useful SA functions for soldiers, law enforcement, homeland defense, and civilian collaborative use; including mapping and navigation, range and bearing, text chat, force tracking, geospatial markup tools, image and file sharing, video playback, site surveys, and many others. This paper describes ATAK, the SA tools that ATAK has built-in, and the ways it is being used by a variety of military, homeland security, and law enforcement users.

    2006-08-01

    Universe Awareness (UNAWE) is an international programme that will expose economically disadvantaged young children aged between 4 and 10 years to the inspirational aspects of modern astronomy. The programme is motivated by the premise that access to simple knowledge about the Universe is a basic birth right of everybody. These formative ages are crucial in the development of a human value system. This is also the age range in which children can learn to develop a 'feeling' for the vastness of the Universe. Exposing young children to such material is likely to broaden their minds and stimulate their world-view. The goals of Universe Awareness are in accordance with two of the United Nations Millennium goals, endorsed by all 191 UN member states, namely (i) the achievement of universal primary education and (ii) the promotion of gender equality in schools. We propose to commence Universe Awareness with a pilot project that will target disadvantaged regions in about 4 European countries (possibly Spain, France, Germany and The Netherlands) and several non-EU countries (possibly Chile, Colombia, India, Tunisia, South Africa and Venezuela). There will be two distinct elements in the development of the UNAWE program: (i) Creation and production of suitable UNAWE material and delivery techniques, (ii) Training of educators who will coordinate UNAWE in each of the target countries. In addition to the programme, an international network of astronomy outreach will be organised. We present the first results of a pilot project developed in Venezuela, where 670 children from different social environments, their teachers and members of an indigenous tribe called Ye´kuana from the Amazon region took part in a wonderful astronomical and cultural exchange that is now being promoted by the Venezuelan ministry of Education at the national level.

    To determine the frequency of hypertension, its associated life style factors and to explore the level of awareness about hypertension among adult populace attending the kidney day and to formulate the strategies to improve the awareness. A total of one hundred participants were interviewed. The structured questionnaire was filled at the spot to obtain socio demographic information after taking verbal informed consent. Height, weight, pulse, blood pressure were recorded. A total of one hundred participants were interviewed. Overall frequency of hypertension in the study population was twenty five percent (25%). The prevalence of hypertension increased with increasing age and body mass index. Only thirty five percent (35%) could define hypertension and this awareness was significantly associated with educational level. Lack of physical activity, card playing and televisionization was observed in sixty percent of participants while thirty three percent were overweight. Fifty nine percent were using additional salt while seventy percent were having meals and snacks outside. High frequency of hypertension, obesity, lack of physical activity, unhealthy nutrition, and faulty dietary habits was observed in the study population. Emphasis on health education and use of electronic and print media is recommended to improve the public awareness about the risk factors and consequences of hypertension like stroke, heart attack, kidney failure etc. (author)

    A considerable gap exists between contraceptive awareness and use. Traditional approaches to measuring awareness are inadequate to properly understand the linkages between awareness and use. The objective of this study was to examine the degree of men's modern contraceptive awareness in Bangladesh and the associated determinants and further testing of a hypothesis that current contraceptive use confers a high degree of method awareness. This study used the couple data set from the Bangladesh Demographic and Health Survey (1999-2000). A two-level, multinomial logistic regression was used with the degree of contraceptive awareness as the dependent variable. The degree of awareness was measured by the reported number of modern contraceptive methods known among men aged 15-59 years. Men's responses on method awareness were classified according to those reported spontaneously and probed. Nearly 100% of the study participants reported having heard of at least one method and about half reported awareness of at least eight different methods of contraception. Multinomial logistic regression analyses showed that older and educated men were more likely to have reported a high degree of awareness. The findings confirmed our hypothesis that current contraceptive use is likely to confer a high degree of modern method awareness among men (pknowledge of contraceptive methods to improve the uptake of especially male-based modern methods.

    Environmental regulators often use environmental policy to induce green investment by firms. However, if an environmental policy fails to exert a long-run effect on regulating the economic agents' behavior, it may be more reasonable to think of the firm as the leader in the game, since the investment in green technology is usually a strategic decision. In this paper, we consider a three-stage Stackelberg game to address the interaction between a profit-maximizing firm (Stackelberg leader) facing emission-dependent demand, and the environmental regulator (Stackelberg follower). The firm decides on the green technology level in the first stage of the game based on its understanding of the regulator's profits function, especially an environmental concern that is introduced as an exogenous variable. In the current research, we show that high levels of the regulator's environmental concerns do not necessarily lead to the choice of green technology by the firm, and green investment level depends on the combined effects of the market and operational factors for a given level of the regulator's environmental concerns. The result also shows that increasing environmental awareness amongst the consumers is an effective way to drive the firm's green investment.

  13. Occlusion-Aware View Interpolation

    2009-01-01

    Full Text Available View interpolation is an essential step in content preparation for multiview 3D displays, free-viewpoint video, and multiview image/video compression. It is performed by establishing a correspondence among views, followed by interpolation using the corresponding intensities. However, occlusions pose a significant challenge, especially if few input images are available. In this paper, we identify challenges related to disparity estimation and view interpolation in presence of occlusions. We then propose an occlusion-aware intermediate view interpolation algorithm that uses four input images to handle the disappearing areas. The algorithm consists of three steps. First, all pixels in view to be computed are classified in terms of their visibility in the input images. Then, disparity for each pixel is estimated from different image pairs depending on the computed visibility map. Finally, luminance/color of each pixel is adaptively interpolated from an image pair selected by its visibility label. Extensive experimental results show striking improvements in interpolated image quality over occlusion-unaware interpolation from two images and very significant gains over occlusion-aware spline-based reconstruction from four images, both on synthetic and real images. Although improvements are obvious only in the vicinity of object boundaries, this should be useful in high-quality 3D applications, such as digital 3D cinema and ultra-high resolution multiview autostereoscopic displays, where distortions at depth discontinuities are highly objectionable, especially if they vary with viewpoint change.

    2017-10-01

    Recommender systems and context awareness is currently a vital field of research. Most hybrid recommendation systems implement content based and collaborative filtering techniques whereas this work combines context and collaborative filtering. The paper presents a hybrid context aware recommender system for books and movies that gives recommendations based on the user context as well as user or item similarity. It also addresses the issue of dimensionality reduction using weighted pre filtering based on dynamically entered user context and preference of context. This unique step helps to reduce the size of dataset for collaborative filtering. Bias subtracted collaborative filtering is used so as to consider the relative rating of a particular user and not the absolute values. Cosine similarity is used as a metric to determine the similarity between users or items. The unknown ratings are calculated and evaluated using MSE (Mean Squared Error) in test and train datasets. The overall process of recommendation has helped to personalize recommendations and give more accurate results with reduced complexity in collaborative filtering.

    Full Text Available Abstract View interpolation is an essential step in content preparation for multiview 3D displays, free-viewpoint video, and multiview image/video compression. It is performed by establishing a correspondence among views, followed by interpolation using the corresponding intensities. However, occlusions pose a significant challenge, especially if few input images are available. In this paper, we identify challenges related to disparity estimation and view interpolation in presence of occlusions. We then propose an occlusion-aware intermediate view interpolation algorithm that uses four input images to handle the disappearing areas. The algorithm consists of three steps. First, all pixels in view to be computed are classified in terms of their visibility in the input images. Then, disparity for each pixel is estimated from different image pairs depending on the computed visibility map. Finally, luminance/color of each pixel is adaptively interpolated from an image pair selected by its visibility label. Extensive experimental results show striking improvements in interpolated image quality over occlusion-unaware interpolation from two images and very significant gains over occlusion-aware spline-based reconstruction from four images, both on synthetic and real images. Although improvements are obvious only in the vicinity of object boundaries, this should be useful in high-quality 3D applications, such as digital 3D cinema and ultra-high resolution multiview autostereoscopic displays, where distortions at depth discontinuities are highly objectionable, especially if they vary with viewpoint change.

    The human immunodeficiency virus/Acquired immunodeficiency syndrome (HIV/AIDS) pandemic continues it deadly assault in different parts of the world. Over 20 million people have died since the first case of AIDS was identified in 1981. Despite increased spending on HIV/AIDS programmes and improved responses by many governments, current global efforts remain entirely inadequate for an epidemic that is continuing to spiral out of control. The objective of this study was to determine the level of awareness about HIV and AIDS among women attending the obstetrics and gynaecology clinic. This Descriptive study was conducted in the Obstetric and Gynaecology clinic at LUMHS, Hyderabad Pakistan from fifth July 2007 to third Dec 2007. A total of 178 women attending obstetric and gynaecology clinic of age 20-55 years were selected randomly. Information was collected by pre-designed questionnaire to assess the level of awareness about HIV/AIDS. About 83.7% women had heard about HIV/AIDS and only 44.3% correctly stated the difference in HIV/AIDS. Only 41.5% of respondents knew how infected person would present, and 55.6% respondents knew that it is transmitted through close sexual relationship, while less than 50% correctly answered about mode of transmission through coughing, sneezing, hand shaking, kissing and ear/nose piercing. Among the respondents, 52.2% correctly answered that screening of blood before transmission can prevent HIV and only 38.2% respondents knew that HIV is preventable disease. Women demonstrated lack of knowledge regarding HIV/AIDS and there are considerable misconceptions and myths in certain aspects which need to be clarified through educating women. (author)

    Mathematical models continue to be essential for deepening our understanding of biology. On one extreme, simple or small-scale models help delineate general biological principles. However, the parsimony of detail in these models as well as their assumption of modularity and insulation make them inaccurate for describing quantitative features. On the other extreme, large-scale and detailed models can quantitatively recapitulate a phenotype of interest, but have to rely on many unknown parameters, making them often difficult to parse mechanistically and to use for extracting general principles. We discuss some examples of a new approach-complexity-aware simple modeling-that can bridge the gap between the small-scale and large-scale approaches. Copyright © 2018 Elsevier Ltd.

    Despite the rapid development of cyber technologies, today we still have very limited attention and communication bandwidth to process the increasing information flow. The goal of the study is to develop a context-aware filter to match the information load with particular needs and capacities. The functions include bandwidth-resolution trade-off and user context modeling. From the empirical lab studies, it is found that the resolution of images can be reduced in order of magnitude if the viewer knows that he/she is looking for particular features. The adaptive display queue is optimized with real-time operational conditions and user's inquiry history. Instead of measuring operator's behavior directly, ubiquitous computing models are developed to anticipate user's behavior from the operational environment data. A case study of the video stream monitoring for transit security is discussed in the paper. In addition, the author addresses the future direction of coherent human-machine vision systems.

    Public awareness of domestic waste characteristics and management (PADWCM) is a prerequisite for a domestic waste management (DWM) plan. In this study, we considered China as a typical example of developing countries to investigate the public perception of environmental pollution (PEP), its PADWCM, and its socioeconomic factors, using questionnaires and statistical methods. The results indicated that the public PEP was mainly due to obvious environmental contamination in local villages, and the PADWCM is still inadequate in rural areas. However, 83.9% of the respondents agreed that DWM is highly necessary. The PADWCM, including the hazard, recyclability, and characteristic pollution caused by domestic waste, was learned mainly from people's direct PEP, experiences, and repurchasing by recyclers. Education period had highly significant positive correlations and regressions with PEP and PADWCM, respectively. Additionally, education directly affected public awareness in different income and age groups. Demonstration projects had a significant positive effect on the awareness of characteristic pollution caused by domestic waste, which was readily perceived. Propaganda had a significant positive influence on the awareness of treatment necessity. Age and gender had no obvious effects on public PEP and PADWCM. Some aspects of PADWCM requiring a deep understanding became stronger as income increased; however, the PADWCM located close to poor people became weaker. Some aspects of PEP could significantly influence the awareness of characteristic pollution caused by domestic waste and awareness of treatment necessity. Therefore, improving environmental education, performing demonstration projects and effective environmental propaganda, increasing people's income, and attracting young people to participate in DWM will be important for enhancing environmental awareness and DWM in rural areas.

    Full Text Available Abstract Background Peripheral arterial disease (PAD is an emerging problem in Sri Lanka, particularly with the ageing population. A considerable number of patients are detected at a late stage with severe limb ischemia or chronic non-healing leg ulceration. Public awareness about PAD is important in developing preventive strategies. Methods A cross sectional study was conducted to assess awareness of PAD among adults aged 40–74 years in a district in Sri Lanka. In total, 2912 adults were selected for the study using a multistage probability proportionate to size sampling technique. Data were collected by an interviewer-administered questionnaire. Participants who were aware of PAD were asked about common risk factors, possible consequences of untreated PAD, and sources of information. Multivariate logistic regression analysis was used to assess the independent predictors of PAD awareness. Results We found that 4.1 % of participants were aware of PAD (95 % confidence interval: 3.4–4.8, which was significantly lower than awareness of other cardiovascular diseases such as cerebrovascular accidents (67.3 % and myocardial infarction (57.6 % (p < 0.001. Being male, an urban resident, and having a higher level of education were independent predictors of high PAD awareness. Conclusions Our findings suggest that a comprehensive PAD awareness program that covers risk factors, consequences, and preventative strategies is needed to enhance public awareness of PAD.

    2013-05-01

    Agriculture is extremely important to Sinaloa contributing 32.31% of the value of all national agricultural production, while the state occupies only 2.9% of the Mexico's area. However it has caused an imbalance in nature due to the low efficiency of irrigation being 49% and using 93% of the surface waters of the region, hence the importance of promoting water awareness. The Water Awareness Strategy for Sinaloa (PLECASIN) 2013- 2015 is a product of the workshop held with water advisers representing 14 utilities, and sponsored by CEAPAS and CONAGUA to address water resources issues in the state, low dam levels and the high level of non-payment, through involving society in the management of water resources. The workshop established strategies to achieve the objective of the National Water Awareness Program (PCA): "Contribute to strengthening the participation of users, organized society and citizens in water management and promote the culture of its good use, through consultation and promotion of cultural and educational activities in coordination with the states, to promote the importance of water resources in social welfare, economic development and the preservation of the ecological wealth, to achieve development sustainable of the nation". PLECASIN was developed using the methodology of strategic planning, beginning with a diagnosis of PCA and the development of strategies pertinent to the current environment in Sinaloa. Activities in the workshop included: defining the vision, mission and objectives, stakeholder analysis, SWOT Matrix, and finally the development of the Logical Framework Analysis Matrix. In addition, the workshop applied the PEEAES tools, using primarily the book of the 5 Waters and application of innovative technologies. The Universidad Autónoma de Sinaloa designed and implemented an Environmental Education Strategy (PEEAES) to foster an environmental awareness through non-formal educational process and includes: a mobile environmental

Objective The main objective of the study is to know the awareness of diabetic retinopathy among new cases of diabetes mellitus (DM) attending the college of medical science- teaching hospital, Bharatpur, Nepal. Method All the diabetic cases referred for ophthalmic consultation and also referred outpatient department cases from other departments to ophthalmic outpatient department was carried out. Detailed demographics of the subjects and their awareness of potential ocular problems from diabetes mellitus were noted. Result Total one hundred and thirty-one patients were enrolled during the study period from 15 November 2016 to 15 May 2017. Brahmin 39.69% and 19.08% Mongolian were the most predominant ethnical group. The predominant group of patients were housewives (41.22%) then followed by service (19.85%), business (13.74%), agriculture (12.21%), others (12.98%). Among 36.64% of the literate patients, 19.85% had passed school level, 9.92% had passed intermediate level, 88.55% were aware of Diabetic retinopathy. Among them majority 88.55% were referred by physician. Family history were present in 35.68% and fundus evaluation was done for the first time in almost half of diabetic cases (64.12%) and diabetic retinopathy was found in 32.06% of total cases in right eye and 30.53% of total cases in left eye. Conclusion Along with the awareness, routine dilated fundoscopy is mandatory for slight threating stage of retinopathy and to reduce the burden of blindness from diabetic retinopathy in Nepal.

    Full Text Available Solid waste is increasingly becoming an important urban challenge as a result from population growth and also the development of economy and culture which has improved the standard of living and the lifestyle of the people. If left unchecked, solid waste could lead to severe environmental degradation. In order to reduce the environmental impact of waste disposal, recycling has been introduced. About twenty percent of our solid waste can be recyclable, rather than disposing it through landfills or incinerators. Residential area is the best place to practice recycling because most of the waste is generated there every day. This research focus on the awareness level and the recycling knowledge among the residents in Johor Bahru City council and Johor Bahru Tengah Municipal Council of Iskandar Malaysia. A total of 500 residents were surveyed and the questionnaires were focused on the waste management and also the recycling knowledge. The results discovered that more than 50% of the residents’ state that they practicing recycle and they also aware of the environmental and economic benefits from recycling. As a conclusion, the residents are prepared for recycling if the recycling amenities are available and easy to reach by them.

    1993-01-01

    Institutions such as World Health Organization and United Nations have considered the necessity to establish programs to control and preserve our environment. From the beginning, industrial development has polluted the air, water and soil, in some cases irreversibly affecting the ecosystems. Rampant use of natural resources and inattention to preventive measures have promoted environmental pollution, along with its hereditary effects, producing brain damage, intoxications, cancer, and respiratory and cardiovascular conditions, among other problems. It is necessary to put aside self-serving materialism and individualism and become aware of this problem. It is necessary to implement environmental policies, foster bioethical responsibility in environmental health research, conduct epidemiologic, biomedical and toxicologic environmental health research works if we are to have a worthy life and an optimal environment.

  8. Environmental Foundations in Germany

    Directory of Open Access Journals (Sweden)

    Thomas Krikser

    2015-05-01

    Full Text Available Foundations in Germany were examined in the context of environmental issues. Data from environmental foundations show that there is huge difference between private and public foundations concerning financial settings. Furthermore, environment is often not the only objective and sometimes not even processed. Our analysis shows that there are different types of foundations with regard to environmental scopes and activities. Although “attractive topics” such as biodiversity and landscape conservation seem to be more important to foundations, less visible topics such as pollution prevention remain merely a “blind spot.” Together, these findings suggest that there is only a limited potential of private foundations compared with public foundations. Nevertheless, there might be an impact on environmental awareness and local sustainability.

    The Internet of Things envisions a web-connected infrastructure of billions of sensors and actuation devices. However, the current state-of-the-art presents another reality: monolithic end-to-end applications tightly coupled to a limited set of sensors and actuators. Growing such applications with new devices or behaviors, or extending the existing infrastructure with new applications, involves redesign and redeployment. We instead propose a modular approach to these applications, breaking them into an equivalent set of functional units (context engines) whose input/output transformations are driven by general-purpose machine learning, demonstrating an improvement in compute redundancy and computational complexity with minimal impact on accuracy. In conjunction with formal data specifications, or ontologies, we can replace application-specific implementations with a composition of context engines that use common statistical learning to generate output, thus improving context reuse. We implement interconnected context-aware applications using our approach, extracting user context from sensors in both healthcare and grid applications. We compare our infrastructure to single-stage monolithic implementations with single-point communications between sensor nodes and the cloud servers, demonstrating a reduction in combined system energy by 22-45%, and multiplying the battery lifetime of power-constrained devices by at least 22x, with easy deployment across different architectures and devices.

    The aim of this study was to assess oral cancer awareness among dentists in Kuwait. A cross-sectional survey was conducted among 200 dentists working at the Ministry of Health Dental Centers and Kuwait University Dental Center using a structured questionnaire. Dentists' knowledge about risk factors of oral cancer and about diagnostic concepts, current practices and opinions, preferred point of referral as well as interest in continuing education were assessed and the responses were analyzed. Of the 200 dentists surveyed, 153 responded (76.5% response rate). The mean knowledge score of the respondents was 20.6 ± 4.0 out of a total score of 30. Thirty-five (22.9%) dentists had consistently high knowledge scores for both risk factors and diagnostic concepts. Of the 153 dentists, 132 (86.3%) were interested in obtaining further information about oral cancer. This study highlighted the need for improved knowledge and education of dental practitioners on oral cancer. Copyright © 2011 S. Karger AG, Basel.

    Abstract Rationale: Laparoscopic total pancreatectomy is a complicated surgical procedure and rarely been reported. This study was conducted to investigate the safety and feasibility of laparoscopic total pancreatectomy. Patients and Methods: Three patients underwent laparoscopic total pancreatectomy between May 2014 and August 2015. We reviewed their general demographic data, perioperative details, and short-term outcomes. General morbidity was assessed using Clavien–Dindo classification and delayed gastric emptying (DGE) was evaluated by International Study Group of Pancreatic Surgery (ISGPS) definition. Diagnosis and Outcomes: The indications for laparoscopic total pancreatectomy were intraductal papillary mucinous neoplasm (IPMN) (n = 2) and pancreatic neuroendocrine tumor (PNET) (n = 1). All patients underwent laparoscopic pylorus and spleen-preserving total pancreatectomy, the mean operative time was 490 minutes (range 450–540 minutes), the mean estimated blood loss was 266 mL (range 100–400 minutes); 2 patients suffered from postoperative complication. All the patients recovered uneventfully with conservative treatment and discharged with a mean hospital stay 18 days (range 8–24 days). The short-term (from 108 to 600 days) follow up demonstrated 3 patients had normal and consistent glycated hemoglobin (HbA1c) level with acceptable quality of life. Lessons: Laparoscopic total pancreatectomy is feasible and safe in selected patients and pylorus and spleen preserving technique should be considered. Further prospective randomized studies are needed to obtain a comprehensive understanding the role of laparoscopic technique in total pancreatectomy. PMID:28099344

    Fetal echocardiography is a well established sensitive tool to diagnose congenital heart disease (CHD) in utero. One of the determinants of effective utilization of fetal echocardiography is its awareness in the general population. The present hospital based study was undertaken to assess the awareness of the need for fetal echocardiography amongst Indian parents. One thousand one hundred and thirty eight consecutive parents who visited the pediatric cardiology outpatient department of a tertiary care centre over a period of two months were asked to fill up a questionnaire that included their demographic data, educational status, history of CHD in children, awareness of fetal echocardiography and source of information and timing of fetal echocardiogram if performed. The data was categorized and awareness was noted in different groups. The awareness in the study population was 2.2%. Awareness was found to be similar across the study population irrespective of the demographics and high risk status of the parents. The awareness of fetal echocardiography, an important tool in reducing the incidence of complex CHD, thereby impacting public health, is alarmingly low in the population studied. Appropriate action to increase awareness of fetal echocardiography needs to be looked into

    2004-07-01

    The present study examined the relations among levels of cognitive functioning, executive dysfunction, and awareness of financial management capabilities among a sample of 42 community-dwelling persons with dementia. Financial tasks on the Measure of Awareness of Financial Skills (MAFS) were dichotomized as simple or complex based on Piaget's operational levels of childhood cognitive development. Severity of global cognitive impairment and executive dysfunction were significantly related to awareness of financial abilities as measured by informant-participant discrepancy scores on the MAFS. For persons with mild and moderate/severe dementia, and persons with and without executive dysfunction, proportions of awareness within simple and complex financial task categories were tabulated. Significantly less awareness of financial abilities occurred on complex compared with simple tasks. Individuals with mild dementia were significantly less aware of abilities on complex items, whereas persons with moderate/severe dementia were less aware of abilities, regardless of task complexity. Similar patterns of awareness were observed for individuals with and without executive dysfunction. These findings support literature suggesting that deficits associated with dementia first occur for complex cognitive tasks involving inductive reasoning or decision-making in novel situations, and identify where loss of function in the financial domain may first be expected.

    2015-08-01

    Full Text Available Context aware applications, which can adapt their behaviors to changing environments, are attracting more and more attention. To simplify the complexity of developing applications, context aware middleware, which introduces context awareness into the traditional middleware, is highlighted to provide a homogeneous interface involving generic context management solutions. This paper provides a survey of state-of-the-art context aware middleware architectures proposed during the period from 2009 through 2015. First, a preliminary background, such as the principles of context, context awareness, context modelling, and context reasoning, is provided for a comprehensive understanding of context aware middleware. On this basis, an overview of eleven carefully selected middleware architectures is presented and their main features explained. Then, thorough comparisons and analysis of the presented middleware architectures are performed based on technical parameters including architectural style, context abstraction, context reasoning, scalability, fault tolerance, interoperability, service discovery, storage, security & privacy, context awareness level, and cloud-based big data analytics. The analysis shows that there is actually no context aware middleware architecture that complies with all requirements. Finally, challenges are pointed out as open issues for future work.

    Full Text Available The climatological characteristics of total ozone over Estonia based on the Total Ozone Mapping Spectrometer (TOMS data are discussed. The mean annual cycle during 1979–2000 for the site at 58.3° N and 26.5° E is compiled. The available ground-level data interpolated before TOMS, have been used for trend detection. During the last two decades, the quasi-biennial oscillation (QBO corrected systematic decrease of total ozone from February–April was 3 ± 2.6% per decade. Before 1980, a spring decrease was not detectable. No decreasing trend was found in either the late autumn ozone minimum or in the summer total ozone. The QBO related signal in the spring total ozone has an amplitude of ± 20 DU and phase lag of 20 months. Between 1987–1992, the lagged covariance between the Singapore wind and the studied total ozone was weak. The spring (April–May and summer (June–August total ozone have the best correlation (coefficient 0.7 in the yearly cycle. The correlation between the May and August total ozone is higher than the one between the other summer months. Seasonal power spectra of the total ozone variance show preferred periods with an over 95% significance level. Since 1986, during the winter/spring, the contribution period of 32 days prevails instead of the earlier dominating 26 days. The spectral densities of the periods from 4 days to 2 weeks exhibit high interannual variability.

    Full Text Available In modern business conditions, the company sends its promotional message through various instruments of promotion, and therefore the different media. One of the instruments of promotion is economic propaganda (advertising, which uses a number of media such as television, radio, newspapers, billboards, Internet and others. By using various media, the company affects the consumer awareness of the brand, spreads information about themselves and the brand, educates consumers, creates a brand image and the like. The aim of this study is to investigate the influence of different media of advertising on consumer awareness of the brand, as well as to investigate that influence in the context of socio-demographic characteristics of respondents. The methods used in the work are historical and research (field and online methods and include a total of 690 respondents from Serbia in the period February-April 2017. For data analysis, we used the independent-samples t-test and the Spearman’s rank correlation coefficient. The results showed that television has the strongest impact on brand awareness. The Internet and billboards follow, while the weakest effect is that of newspapers and radio. Results show that in the context of gender, age, education and income of respondents, there are reasons to analyze the impact of television, radio, newspapers, billboards and the Internet to consumer awareness of the brand in a different manner. The contribution of the thesis is also reflected in the fact that, on the basis of the obtained results, the authors give recommendations, when it comes to perception and brand awareness, on the media that are an adequate promotional instrument for a particular segment of consumers.

    2015-05-01

    Somatic complaints are common in childhood. Research has shown their relationship with emotional awareness and maladjustment. The study had three objectives: 1) to analyze the prevalence of somatic complaints; 2) To explore the relationships between the variables evaluated: somatic complaints, differentiating emotions, verbal sharing of emotions, not hiding emotions, body awareness, attending to others' emotions, analysis of emotions, and personal, social, family, and school maladjustments; and 3) To identify predictors of somatic complaints. The study included a total of 1,134 randomly selected schoolchildren of both sexes between 10-12 years old (M=10.99; SD=0.88). The Somatic Complaint List, Emotional Awareness Questionnaire, and Self-reported Multifactor Test of Childhood Adaptation were used to gather information. The results showed that the prevalence of somatic complaints was 90.2%, with fatigue, headache and stomachache being the most frequently. Dizziness and headache were more common in girls, and the frequency of complaints decreases with age. Somatic complaints are negatively related to emotional awareness, and positively related to maladjustment. The variables that contribute the most to the prediction of somatic complaints are personal maladjustment (25.1%) and differentiating emotions (2.5%). The study shows that personal maladjustment is the best predictor of somatic complaints; the more emotional awareness and better adapted the child, the fewer somatic complaints they lodge. Childhood is a stage with significant physical discomfort. Copyright © 2014 Asociación Española de Pediatría. Published by Elsevier España, S.L.U. All rights reserved.

    Exploration and searching for life in other stellar systems have shown that its development and sustainability depend of very specific environment conditions. Due to that, preservation of the equilibrium of this conditions in our planet is very important, because small changes on it can generate high repercussions in its habitability. This work shows some preliminary results from an environmental monitoring network (RACIMO, Red Ambiental Ciudadana de Monitoreo) conformed by automatic meteorologic stations located on seven high-schools at metropolitan zone of Bucaramanga, Colombia. Data recorded by monitoring network are stored in an open web repository which can be accessed by citizens from any place with internet connection. These stations called UVAs, were developed under creative commons license, that is to say, software, hardware and data free, besides these can be built by students due to its flexibility. The UVAs are modular and re-programmable, that is, any sensor can be added to the stations and then re-configure its firmware remotely. Besides, UVAs work in automatic way, after the first setup, they will be self-sufficient and won't depend of human intervention. The data, of each UVA, are recorded with a temporal synchrony and then are upload at central repository by means of WiFi, ethernet or GSM connection. The stations can be power supplied by a solar system or the electrical grid. Currently, UVA record variables such as: pressure, temperature, humidity, irradiance, iluminance, ambient noise, rain, cloudiness, CO2 and NO2 concentration, lighting, seismic movements and its geographic position. On other hand, a calibration system has been developed to validate the data recorded by RACIMO. This project, started from an astroclimate an exoplanets habitability conditions, became an independent citizen science project to rise awareness about the very particular conditions enjoyed in our Earth planet.

    Total lymphoid irradiation by itself can produce sufficient immunosuppression to prolong the survival of a variety of organ allografts in experimental animals. The degree of prolongation is dose-dependent and is limited by the toxicity that occurs with higher doses. Total lymphoid irradiation is more effective before transplantation than after, but when used after transplantation can be combined with pharmacologic immunosuppression to achieve a positive effect. In some animal models, total lymphoid irradiation induces an environment in which fully allogeneic bone marrow will engraft and induce permanent chimerism in the recipients who are then tolerant to organ allografts from the donor strain. If total lymphoid irradiation is ever to have clinical applicability on a large scale, it would seem that it would have to be under circumstances in which tolerance can be induced. However, in some animal models graft-versus-host disease occurs following bone marrow transplantation, and methods to obviate its occurrence probably will be needed if this approach is to be applied clinically. In recent years, patient and graft survival rates in renal allograft recipients treated with conventional immunosuppression have improved considerably, and thus the impetus to utilize total lymphoid irradiation for its immunosuppressive effect alone is less compelling. The future of total lymphoid irradiation probably lies in devising protocols in which maintenance immunosuppression can be eliminated, or nearly eliminated, altogether. Such protocols are effective in rodents. Whether they can be applied to clinical transplantation remains to be seen

    2017-11-22

    Optimality of decision rules (patterns) can be measured in many ways. One of these is referred to as length. Length signifies the number of terms in a decision rule and is optimally minimized. Another, coverage represents the width of a rule’s applicability and generality. As such, it is desirable to maximize coverage. A totally optimal decision rule is a decision rule that has the minimum possible length and the maximum possible coverage. This paper presents a method for determining the presence of totally optimal decision rules for “complete” decision tables (representations of total functions in which different variables can have domains of differing values). Depending on the cardinalities of the domains, we can either guarantee for each tuple of values of the function that totally optimal rules exist for each row of the table (as in the case of total Boolean functions where the cardinalities are equal to 2) or, for each row, we can find a tuple of values of the function for which totally optimal rules do not exist for this row.

    2017-10-01

    Professionals who provide nutrition education and consulting to the public are encouraged to take into account the health, environmental and social contexts that influence health-related attitudes and behaviours in the population. This paper examined the awareness of shifts in population health outcomes associated with the nutrition transition in Vietnam among university nutrition lecturers, health professionals and school education professionals. Most of these professionals held accurate views of the current population health issues in Vietnam. However, they differed in their awareness of the seriousness of overweight and obesity. Although the majority indicated that the prevalence of obesity and non-communicable diseases (NCDs) had increased, nearly half believed that the government should complete its attempts to control undernutrition before trying to control obesity. More health professionals believed that food marketing was responsible for the growing prevalence of children's obesity, and more of them disapproved of the marketing of less healthy food to children. In contrast, the university nutrition lecturers were least aware of food marketing and the seriousness of obesity. Of the three groups, the university nutrition lecturers held less accurate perceptions of nutrition transition problems and their likely drivers. There is an urgent need for greater provision of public nutrition education for all three groups of professionals. © The Author 2016. Published by Oxford University Press. All rights reserved.

    Full Text Available Although sustainability is of utmost importance, anecdotal evidence suggests that the concept is not adequately implemented in many developing countries. This paper investigates industry stakeholders’ awareness of the current state of, factors driving, and barriers hindering the adoption of sustainable construction (SC in Cambodia. Using an empirical questionnaire survey targeting local construction professionals, respondents were invited to rate their level of awareness, knowledge and understanding of SC, as well as to rate the level of importance of 31 drivers and 10 barriers identified from the seminal literature. The data set was subjected to the relative importance index method. The results suggest that the industry-wide adoption of SC practices is poor, which is believed to be due to a lack of awareness and knowledge, and reluctance to adopt new sustainable technologies. Furthermore, more efforts must be put into the selection of more durable materials for the extension of buildings’ lives and to minimize material consumption, as well as to develop energy-efficient buildings with minimal environmental impact and a healthy indoor environment, so that the ability of future generations to meet their own needs will not be compromised. The outcomes of this study have enriched knowledge about the current state of, drivers of, and barriers to sustainable construction in a typical developing economy. Although the outcomes of this study were a short scoping exercise, it has formed a significant base for future SC work within Cambodia.

    Ragpickers are informal workers who collect recyclable materials to earn a small wage on daily basis. They work in vulnerable conditions and awareness regarding occupational and environmental hazard is essential for them. To study the effectiveness of awareness program on various occupational health hazards among the ragpickers. This interventional study was conducted from May through October 2016 among the ragpickers living near field practice area of Department of Community Medicine and those living in slum areas around HAHC Hospital, New Delhi, India. The awareness regarding occupational and environmental health hazards was assessed using a pretested and predesigned pro forma. Snowball sampling technique was used to select the ragpickers from the various areas. Health awareness and education package was designed for the ragpickers. The package was delivered by medical officers and health workers. A posttest assessment was done 2 weeks after the awareness activity. Among 150 ragpickers, there was significant improvement in knowledge immediate post training on knowledge of occupational hazard and hygiene. Efforts should be put to develop training materials on occupation and environmental health and injury issue relating to waste management.

    Background Children’s exposure to food marketing is one environmental determinant of childhood obesity. Measuring the extent to which children are aware of food brands may be one way to estimate relative prior exposures to food marketing. This study aimed to develop and validate an Australian Brand Awareness Instrument (ABAI) to estimate children’s food brand awareness. Methods The ABAI incorporated 30 flashcards depicting food/drink logos and their corresponding products. An abbreviated version was also created using 12 flashcards (ABAI-a). The ABAI was presented to 60 primary school aged children (7-11yrs) attending two Australian after-school centres. A week later, the full-version was repeated on approximately half the sample (n=27) and the abbreviated-version was presented to the remaining half (n=30). The test-retest reliability of the ABAI was analysed using Intra-class correlation coefficients. The concordance of the ABAI-a and full-version was assessed using Bland-Altman plots. The ‘nomological’ validity of the full tool was investigated by comparing children’s brand awareness with food marketing-related variables (e.g. television habits, intake of heavily promoted foods). Results Brand awareness increased with age (plevels of brand awareness. It was shown to be a valid and reliable tool and may allow quantification of brand awareness as a proxy measure for children’s prior food marketing exposure. PMID:26222624

    To assess the awareness about glaucoma and the factors affecting it in urban Punjab population. Study Design: Cross-sectional study. Place and Duration of Study: Study was conducted in March-April 2011 in Rawalpindi District Punjab, Pakistan. Material and Methods: Glaucoma awareness study was conducted on urban population of Rawalpindi, Islamabad, Lahore and Taxila. Individuals belonging to medical profession (doctors, nurses and paramedics etc) were not included. Demographic details and educational status of all participants were documented. A brief structured close-ended study questionnaire was used to collect information about their awareness of risk factors, treatment aspects and complication of glaucoma. Results: There were 729 participants in the study. Majority were females (60.1%) and adults (76.1%). Literacy level of 40.2% was up to matriculate level. The study indicated that the awareness level about glaucoma was low especially about the recognition of high-risk groups and symptoms. Only one-third of respondents i.e. 32.6% had an idea about the symptoms of the disease and 27.4% participants had awareness of glaucoma as a blinding eye disease. Determinants of glaucoma awareness amongst study participants were gender, age, education level and occupation. Conclusion: Awareness of glaucoma was quite low among the urban population in Punjab. There is need of increased public health education to reduce glaucoma associated blindness and its burden on society. (author)

    The concept of sustainability has begun to gain importance in fashion industry. The companies, which are acting in sustainable fashion, want to gain recognition, inform the consumer about their products and services and generate a demand from the consumers. But the awareness of the consumers about sustainability is still an unknown. In this study, the level of awareness of consumers about sustainable fashion was tried to be determined with a survey established in Turkey in which the socio-demographic characteristics and the awareness level of the participants were questioned. The result of the survey showed that the level of awareness among the participants is not so high and the perception of sustainability is mostly limited to some aspects of sustainable fashion such as “Usage of organic materials” and “Recycling”. Besides, the analysis of the relation between socio-demographic characteristics and awareness level of sustainable fashion showed that the awareness level increased with the education level and income to some extent. But specifically, the males and the participants aged between 24-29 have higher levels of awareness compared with the other participants.

    There is an increasing recognition by commercial and civil space operators of the need for space situational awareness (SSA) data to support ongoing conjunction analysis, maneuver planning, and radio frequency interference mitigation as part of daily operations. While some SSA data is available from the Joint Space Operations Center via the Space Track web site, access to raw observations and photometric data is limited due to national security considerations. These data, however, are of significant value in calibrating intra- and inter-operator orbit determination results, determining inter-system biases, and assessing operating profiles in the geostationary orbit. This paper details an ongoing collaborative effort to collect and process optical observations and photometric data using a network of low-cost telescope installations and shows how these data are being used to support ongoing operations in the Space Data Center. This presentation will demonstrate how by leveraging advance photometric processing algorithms developed for Missile Defense Agency and the Ballistic Missile Defense (BMD) mission ExoAnalytic and AGI have been able to provide actionable SSA for satellite operators from small telescopes in less than optimal viewing conditions. Space has become an increasingly cluttered environment requiring satellite operators to remain forever vigilant in order to prevent collisions to preserve their assets and prevent further cluttering the space environment. The Joint Space Operations Center (JSpOC), which tracks all objects in earth orbit, reports possible upcoming conjunctions to operators by providing Conjunction Summary Messages (CSMs). However due to large positional uncertainties in the forward predicted position of space objects at the time closest approach the volume of CSMs is excessive to the point that maneuvers in response to CSMs without additional screening is cost prohibitive. CSSI and the Space Data Association have been able to screen most

    Background Genetic testing for several cancer susceptibility syndromes is clinically available; however, existing data suggest limited population awareness of such tests. Purpose To examine awareness regarding cancer genetic testing in the U.S. population aged ≥25 years in the 2000, 2005, and 2010 National Health Interview Surveys. Methods The weighted percentages of respondents aware of cancer genetic tests, and percent changes from 2000–2005 and 2005–2010, overall and by demographic, family history, and healthcare factors were calculated. Interactions were used to evaluate the patterns of change in awareness between 2005 and 2010 among subgroups within each factor. To evaluate associations with awareness in 2005 and 2010, percentages were adjusted for covariates using multiple logistic regression. The analysis was performed in 2012. Results Awareness decreased from 44.4% to 41.5% (pAwareness increased between 2005 and 2010 in most subgroups, particularly among individuals in the South (p-interaction=0.03) or with a usual place of care (p-interaction=0.01). In 2005 and 2010, awareness was positively associated with personal or family cancer history and high perceived cancer risk, and inversely associated with racial/ethnic minorities, age 25–39 or ≥60 years, male gender, lower education and income levels, public or no health insurance, and no provider contact in 12 months. Conclusions Despite improvement from 2005 to 2010, ≤50% of the U.S. adult population was aware of cancer genetic testing in 2010. Notably, disparities persist for racial/ethnic minorities and individuals with limited health care access or income. PMID:24745633

    2012-03-01

    We explore the impact of awareness on epidemic spreading through a population represented by a scale-free network. Using a network mean-field approach, a mathematical model for epidemic spreading with awareness reactions is proposed and analyzed. We focus on the role of three forms of awareness including local, global, and contact awareness. By theoretical analysis and simulation, we show that the global awareness cannot decrease the likelihood of an epidemic outbreak while both the local awareness and the contact awareness can. Also, the influence degree of the local awareness on disease dynamics is closely related with the contact awareness.

    1999-01-01

    The ECE Committee on Environmental Policy included the Environmental Performance Review of Latvia in its work programme in May 1997. The review team prepared a report on the environmental performance of Latvia before, during and after the review mission in Riga in April 1998. The report by the review team, including draft recommendations for the solution of existing problems in national environmental policy and management, was submitted for evaluation to the ECE Committee on Environmental Policy at its annual session in Geneva, on 1 October 1998. A high-level delegation from Latvia attended this session. It was headed by the State Minister for Environmental Protection and also included representatives of the Ministry of Transport and the Ministry of Welfare. The evaluation by the Committee was based on the in-depth preparation by two reviewing countries, Portugal and Ukraine. At the end of its evaluation, the Committee agreed on a final set of recommendations for inclusion in this publication. The consideration of the EPR report confirmed the strategy that has been applied to Latvian environmental policy and management during the transition period. The inherited acute environmental problems have been tackled essentially on a case by case basis. The long-term solution of the problems will have to be accompanied also by strategic orientations for environmental policy. The development of such orientations in co-operation with both governmental and non-governmental partners is a need also related to the efforts by Latvia to approach European practices of environmental management. The Latvian Ministry of Environmental Protection and Regional Development is fully aware of the considerable resources that are required at all levels for the full transformation to such practices

    Full Text Available FIABA ONLUS (Italian Fund for Elimination of Architectural Barriers was founded in 2000 with the aim of promoting a culture of equal opportunities and, above all, it has as its main goal to involve public and private institutions to create a really accessible and usable environment for everyone. Total accessibility, Total usability and Total mobility are key indicators to define quality of life within cities. A supportive environment that is free of architectural, cultural and psychological barriers allows everyone to live with ease and universality. In fact, people who access to goods and services in the urban context can use to their advantage time and space, so they can do their activities and can maintain relationships that are deemed significant for their social life. The main aim of urban accessibility is to raise the comfort of space for citizens, eliminating all barriers that discriminate people, and prevent from an equality of opportunity. “FIABA FUND - City of ... for the removal of architectural barriers” is an idea of FIABA that has already affected many regions of Italy as Lazio, Lombardy, Campania, Abruzzi and Calabria. It is a National project which provides for opening a bank account in the cities of referring, in which for the first time, all together, individuals and private and public institutions can make a donation to fund initiatives for the removal of architectural barriers within its own territory for a real and effective total accessibility. Last February the fund was launched in Rome with the aim of achieving a Capital without barriers and a Town European model of accessibility and usability. Urban mobility is a prerequisite to access to goods and services, and to organize activities related to daily life. FIABA promotes the concept of sustainable mobility for all, supported by the European Commission’s White Paper.

    1987-01-01

    The multitude of papers and conferences in recent years on the use of very large megavoltage radiation fields indicates an increased interest in total body, hemibody, and total nodal radiotherapy for various clinical situations. These include high dose total body irradiation (TBI) to destroy the bone marrow and leukemic cells and provide immunosuppression prior to a bone marrow transplant, high dose total lymphoid irradiation (TLI) prior to bone marrow transplantation in severe aplastic anemia, low dose TBI in the treatment of lymphocytic leukemias or lymphomas, and hemibody irradiation (HBI) in the treatment of advanced multiple myeloma. Although accurate provision of a specific dose and the desired degree of dose homogeneity are two of the physicist's major considerations for all radiotherapy techniques, these tasks are even more demanding for large field radiotherapy. Because most large field radiotherapy is done at an extended distance for complex patient geometries, basic dosimetry data measured at the standard distance (isocenter) must be verified or supplemented. This paper discusses some of the special dosimetric problems of large field radiotherapy, with specific examples given of the dosimetry of the TBI program for bone marrow transplant at the authors' hospital

    Literature on somatization suggests that patients suffering from medically unexplained symptoms are less aware of their emotions and use maladaptive coping strategies when coping with everyday problems. In addition, coping is hypothesized to mediate between emotion awareness and medically unexplained symptoms. Scientific evidence for the relevance of this hypothesis for children with functional abdominal pain (FAP) is, however, lacking. Therefore, the purpose of the present study was to investigate this hypothesis in Dutch children with functional abdominal pain (FAP), aged 7-18 years. Between April 2007 and April 2010, a total of 114 referred children with FAP, 235 schoolchildren without abdominal pain and 407 schoolchildren with some abdominal pain (AP) of diverse etiology filled out questionnaires concerning their pain, emotion awareness and coping. MANOVA was used to investigate group differences in emotional awareness and coping. Structural equation modeling was used to investigate the mediational role of coping. The results showed that children with FAP scored significantly lower on most aspects of emotion awareness than children without AP, although these differences were small. Contrary to expectations, children with FAP were more aware of a link between emotions and bodily sensations than children without AP. As for coping, we found that children with FAP used avoidant coping more often than children without AP. Overall, children with FAP mostly did not differ in their emotional awareness and coping compared to children with some AP. Problem focused coping had a small mediating effect for two aspects of emotion awareness. We conclude that children with FAP show only small differences in emotion awareness and coping compared to children without AP, and are practically no different from children with some AP. Contrary to common belief, it can be questioned whether emotion awareness and general coping are useful targets for psychological treatments of FAP to

    Hepatitis B is the major health problem globally casting an enormous burden on health care system and major source of patient's misery. It is also an important cause of hepatocellular carcinoma and is likely to remain a serious health problem resulting in substantial morbidity and mortality for several decades to come. Objective of the study was to determine the level of awareness regarding hepatitis B among women attending obstetric and gynaecology clinic at Isra university Hospital. It was descriptive study and conducted in Obstetric and Gynaecology, Outpatient Department of Isra University Hospital, Hyderabad, Sindh from 2nd January to 3rd June 2008. Total 121 women of 20-50 years were gathered by sample of convenience. Information was collected on pre designed questionnaire containing questions regarding basic knowledge of disease, its causative organism, route of transmission and its prevention. Informed consent was taken. All the data was analyzed by computer software Programme of Social Sciences (SPSS version 11.0). Out of 121 women, 82 (67.76%) women correctly responded that virus is a cause of hepatitis. When they were asked about the organs affected by hepatitis B infection, 91 (75.20%) correctly mentioned liver, while 30 (24.79%) gave incorrect answer. Regarding mode of transmission of HBV 41 (33.88%) mentioned infected blood transfusion, 49 (40.49%) contaminated needles, 46(38.0%) un-sterilised instruments, 21 (17.35%) from mother to child and only 23 (19.0%) mentioned sexual intercourse. Only 51 (42.14%) women knew that vaccine is available for prevention. This study found that the knowledge about hepatitis B virus among women is inadequate and there are certain misconceptions regarding its mode of transmission through sharing room, touching etc which needs to be clarified. Majority of women don't know that HBV infection can be prevented by using condoms. (author)

    2011-12-01

    Full Text Available Brand awareness, together with other behavioural indicators (sympathy, trust, image, satisfaction or loyalty, is one of the main vectors that has an essential contribution to the outline of brand equity in general and to that of retail brand, in particular. The perception upon these indicators must be taken into consideration by production, service or retail companies in order to be able to identify their position on target markets, and in order to be able to create an adequate strategy that would help them reach the desired positioning. The aim of this paper is, on one hand, to reveal both the dimensions of brand awareness, and the relationship between these and consumers brand perception and, on the other hand, to offer a suitable instrument to measure awareness level of various retail chains. Questioning of almost 4.000 consumers indicates a significant awareness of the retailers that have been on the selected market for a longer period of time.

    A recent meta-analysis has shown precuneus, angular gyri, anterior cingulate gyri, and adjacent structures to be highly metabolically active in support of resting consciousness. We hypothesize that these regions constitute a functional network of reflective self-awareness thought to be a core...... function of consciousness. Seven normal volunteers were asked to think intensely on how they would describe the personality traits and physical appearance of themselves and a neutral reference person known to all the subjects (the Danish Queen). During each of the four conditions cerebral blood flow...... during reflective self-awareness. The commonality between the neural networks of the resting conscious state and self-awareness reflects the phenomenological concept of a fundamental contribution of reflective self-awareness to the contents and coherence of the conscious state....

    This report presents methods for continuous measures for Situation Awareness and Workload. The objective has been to identify, develop and test the new measures, and compare them to instruments that require interruptions of scenarios. The new measures are: (1) the Visual Indicator of Situation Awareness (VISA); where Situation Awareness is scored from predefined areas of visual interest critical for solving scenarios. Visual monitoring of areas was recorded by eye-movement tracking. (2) Workload scores reflected by Extended Dwell Time (EDT) and the operator Activity Level. EDT was calculated from eye-movement data files, and the activity level was estimated from simulator logs. Using experimental data from the 1996 CASH NRC Alarm study and the 1997 Human Error Analysis Project/ Human-Centred Automation study, the new measurement techniques have been tested and evaluated on a preliminary basis. The results showed promising relationships between the new continuous measures of situation awareness and workload, and established instruments based upon scenario interruptions. (author)

    The intent-aware diversification framework considers a set of aspects associated with items to be recommended. A baseline recommendation is greedily re-ranked using an objective that promotes diversity across the aspects. In this paper the framework is analysed and a new intent-aware objective is derived that considers the minimum variance criterion, connecting the framework directly to portfolio diversification from finance. We derive an aspect model that supports the goal of minimum varianc...

    Academic ethical awareness is an important aspect especially for nursing students who will provide ethical nursing care to patients in future or try to tread the path of learning toward professional acknowledgement in nursing scholarship. The purpose of this study was to explore academic ethical awareness and its related characteristics among undergraduate nursing students. This study commenced the survey with cross-sectional, descriptive questions and enrolled convenient samples of 581 undergraduate nursing students from three universities in South Korea. It was investigated with structured questionnaires including general characteristics and academic ethical awareness related. Ethical considerations: This study was reviewed and approved by the Institutional Review Board at National University. Academic ethical awareness was the highest regarding behaviors violating the respect or confidentiality of patients and cheating on exams, while it was the lowest for inappropriate behaviors in class. From the result of general characteristics difference, male students showed higher score than female students in relative; first-year students showed higher score than other year students; the higher score was rated from students who were highly satisfied with their major than the other not satisfied with their major; and students with low academic stress showed higher ethical awareness score than persons with higher stress. Personal behaviors were rated with low ethical awareness in relative, but items related to public rules and actual effects on patients or others were rated with higher score. Nursing satisfaction and academic stress are main factors on ethical awareness. To improve overall ethical awareness level of nursing students, it is required to provide more education about the importance of personal behaviors in class and need to improve the understanding of how it will be connected with future situation and effect.

    Working memory, phonological awareness and spelling hypothesis. To verify the relationship between working memory, phonological awareness and spelling hypothesis in pre-school children and first graders. Participants of this study were 90 students, belonging to state schools, who presented typical linguistic development. Forty students were preschoolers, with the average age of six and 50 students were first graders, with the average age of seven. Participants were submitted to an evaluation of the working memory abilities based on the Working Memory Model (Baddeley, 2000), involving phonological loop. Phonological loop was evaluated using the Auditory Sequential Test, subtest 5 of Illinois Test of Psycholinguistic Abilities (ITPA), Brazilian version (Bogossian & Santos, 1977), and the Meaningless Words Memory Test (Kessler, 1997). Phonological awareness abilities were investigated using the Phonological Awareness: Instrument of Sequential Assessment (CONFIAS - Moojen et al., 2003), involving syllabic and phonemic awareness tasks. Writing was characterized according to Ferreiro & Teberosky (1999). Preschoolers presented the ability of repeating sequences of 4.80 digits and 4.30 syllables. Regarding phonological awareness, the performance in the syllabic level was of 19.68 and in the phonemic level was of 8.58. Most of the preschoolers demonstrated to have a pre-syllabic writing hypothesis. First graders repeated, in average, sequences of 5.06 digits and 4.56 syllables. These children presented a phonological awareness of 31.12 in the syllabic level and of 16.18 in the phonemic level, and demonstrated to have an alphabetic writing hypothesis. The performance of working memory, phonological awareness and spelling level are inter-related, as well as being related to chronological age, development and scholarity.

    Real-world images usually contain vivid contents and rich textural details, which will complicate the manipulation on them. In this paper, we design a new framework based on content-aware synthesis to enhance content-aware image retargeting. By detecting the textural regions in an image, the textural image content can be synthesized rather than simply distorted or cropped. This method enables the manipulation of textural & non-textural regions with different strategy since they have different...

    Lack of awareness and understanding of youth development law amongst youth and policy makers is quite significant. Among the reasons that have been identified to be the root cause of this weakness is due to the failure or less priority given by the youth societies and related organization which are responsible in providing quality programmes for youth. In light of the above gap, the paper examines youth awareness on youth development law from the perspective of policy makers and youth themse...
