    Starting from the hypothesis that environmental concern is socially built, dynamic and permeable to current situation and the news, this work is two aimed: a) To study potential differences in environmental concern due to socio demographic variables, in order to define an environmentally concerned profile; b) To analyze the evolution of this concern in Spanish society for the last seven years. To archive this purposes, data originating in Spanish sociological research centre (CIS) opinion surveys has been used. No significant relation among socio demographic variables and environmental concern has been found. Percentage of people concerned about environment is quite low (about 2%), above all in relation to other issues as economic situation, terrorism or immigration. However, this percentage has increased remarkably when some environmentally threatening event has been present (as forest fi res, or Prestige oil spill). It has also been detected that this concern is gradually increasing, possibly due to growing knowledge of economic and technical development and environmental damage relation. Environmental concern is different according to which territorial level people has in mind when reporting their opinion (world, country or region). (Author) 31 refs.

  3. Food irradiation: Public opinion surveys

    International Nuclear Information System (INIS)

    The Canadian government are discussing the legislation, regulations and practical protocol necessary for the commercialization of food irradiation. Food industry marketing, public relations and media expertise will be needed to successfully introduce this new processing choice to retailers and consumers. Consumer research to date including consumer opinion studies and market trials conducted in the Netherlands, United States, South Africa and Canada will be explored for signposts to successful approaches to the introduction of irradiated foods to retailers and consumers. Research has indicated that the terms used to describe irradiation and information designed to reduce consumer fears will be important marketing tools. Marketers will be challenged to promote old foods, which look the same to consumers, in a new light. Simple like or dislike or intention to buy surveys will not be effective tools. Consumer fears must be identified and effectively handled to support a receptive climate for irradiated food products. A cooperative government, industry, health professional, consumer association and retailer effort will be necessary for the successful introduction of irradiated foods into the marketplace. Grocery Products Manufacturers of Canada is a national trade association of more than 150 major companies engaged in the manufacture of food, non-alcoholic beverages and array of other national-brand consumer items sold through retail outlets

    1994-06-01

    In the last years research on the didactics of Psychiatry and opinions of medical students on Psychiatry has gained great interest. The authors think that this research could be useful for the improvement of didactics, for better understanding the meanings of professional choice, the identity of psychiatrist and their relationship with colleagues in other medical field. The goal of this research work was a preliminary survey of Genoese University Medical Student's opinions about psychiatry didactics, and choice of specialization. A questionnaire was submitted to all the students who passed Clinical Psychiatry examination in the period from November 1987 to December 1988. The students were divided in two randomized groups: the first group of students (224) was submitted to the questionnaire immediately after Clinical Psychiatry examination; while to the second group of students (66) the questionnaire was mailed. The aim of the questions was to assess the student's opinions on psychiatry, psychoanalysis, psychotherapy, the career they wanted to take up, and the difficulties of studying psychiatry: 69% of the students of the first group and 42% of the students of the second group answered the questionnaire. Female students answered that they preferred psychiatric specialization more than their male colleagues did, but the difference has no statistical importance. In most cases, the students who answered that they have taken into account psychiatry as a choice of specialisation, are more interested in medical specialties (primary care, etc.) than in surgical specialties. Most of the medical students declare some emotional troubles (anxiety, sleeplessness, problem in social relations).(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7934737

    Full Text Available Abstract Background Continuing Education (CE for chiropractors is mandatory for licensure in most North American jurisdictions. Numerous chiropractic colleges have begun collaborating with universities to offer master's degree programs. Distance education master's degree programs may be desirable to allow full-time practicing doctors to further their post-graduate education. The present survey sought to answer three questions. First, what is the level of satisfaction of chiropractors with their continuing education? Second, what is the level of interest of chiropractors in online master's degree programs? Lastly, what is the response rate of chiropractors to an online survey? Methods An online survey consisting of 22 multiple choice questions was e-mailed to 1000 chiropractors randomly selected from the mailing list of an online chiropractic newsletter. Upon completion of the questionnaire, participants' answers were saved on a secure site. Data analysis included evaluation of the demographic characteristics of the respondents, their opinions of and patterns of taking CE including online education, preferred learning formats, and their interest in proposed online master's degree programs. A survey response rate was determined. Results Nearly 86% of respondents felt their previously completed CE courses were either somewhat or extremely satisfactory. Over ninety percent of respondents who had completed online or distance CE coursesfound them to be somewhat or extremelysatisfactory. Almost half the respondents indicated that they most preferred online distance learning, while 34.08% most preferred face-to-face interaction. Fifty-three percent of respondents indicated an interest in starting a master's degree program; however 70.46% of respondents were interested in an online master's degree program that would offer CE credit. A response rate of 35.8% was obtained. Conclusion Satisfaction among chiropractors with CE programs is high. The notion of

  20. More than 30 years of opinion of French people on nuclear risks - Special release of the 2012 IRSN opinion survey

    International Nuclear Information System (INIS)

    Illustrated by many graphs and tables, this report comments and discusses the evolution of opinion surveys performed in France on the perception of nuclear risks through thirty annual IRSN opinion surveys. It appears that the opinion on nuclear is rather steady, and that French people have a rather rational perception of risk hierarchy. The first part outlines that unemployment is the main concern for French people, and that environmental concerns depend on current events. The second part analyses the perception of the nuclear risk with respect to other societal concerns and to other risks, and discusses the evolution of opinion from a quantitative to a qualitative sensitivity. The third part addresses the representations people have of nuclear activities and how they challenge the reality: perception of nuclear plants and of radioactive wastes, fear of a serious accident. The last part deals with issues related to responsibilities, abilities and governance: how actors of nuclear risk management are perceived, and expectations in terms of transparency and opinion plurality

    2013-06-01

    This report has been developed as an integral part of the PVMapper project, funded by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy’s SunShot program. The objective of the SunShot program is to reduce the total costs of solar energy systems. The scope of PVMapper is to develop a geographic information system (GIS) based project planning tool to identify optimal utility-scale solar facility sites. The specific objectives of the project are to 1) develop the software on an open-source platform; 2) integrate the appropriate data sets and GIS layers; 3) include a measure of social risk and public acceptance; 4) enable customization of variable weights; 5) provide a free and accessible platform for software download; and 6) provide a sustainability plan to ensure future relevance of the software. When completed, PVMapper is intended to be used by solar developers, Authorities Having Jurisdiction (AHJs), and other interested parties. This project supports SunShot’s objective by reducing the non-hardware balance of system costs (“soft costs”) for utility-scale solar project development. In order to accomplish the third project objective – including a measure of social risk and public acceptance within PVMapper – the project team has developed a time-series public opinion survey, administered yearly over the course of the three-year project. This report highlights the results and preliminary analyses from the second survey in this series. While the results of this survey are valuable to both PVMapper and future utility-scale solar development, the time-series design is extremely important. The completion of the series enables the extension of the dataset to much richer information. For example, the research team altered this iteration to sharpen the focus on specific topics (those posing potentially higher risks) and target specific locations in the oversample (such as communities near existing facilities).

    Full Text Available In order to shape tax reform it is necessary objectively to assess the current stateof-the-art of and of the outlook for the tax system. After having reviewed all previous reforms in the light of the consumption-based (interest-adjusted concept of direct taxation, which was almost systematically implemented in Croatia in 1994, we present the results of a broad expert opinion survey about the Croatian tax system. The most interesting results suggest the maintenance/(reintroduction of different tax incentives and reduced VAT rates, rejection of a flat tax as well as decrease of tax brackets, an increase in alcohol and tobacco duties, the introduction of a financial activities tax, a further shift from income to consumption, a decrease of the tax share in GDP and a belief in the behavioral responsiveness of tax decreases/exemptions, as well as a firm commitment to the principle of equity. The last three economic views/values are important predictors of other tax attitudes.

  3. Public Opinion Survey-Energy-The Present and the Future

    International Nuclear Information System (INIS)

    During the academic year 2007/08 the Department of Applied Physics of the Faculty of Electrical Engineering and Computing conducted a public opinion survey entitled 'Energy - The Present and the Future' among student population of 1439 individuals age 18-20. The tested population consisted of the University of Zagreb nine faculties' students: the Faculty of Electrical Engineering and Computing - 367 students, the Faculty of Food Technology and Biotechnology - 149 students, the Faculty of Chemical Engineering and Technology - 118 students, the Faculty of Civil Engineering - 102 students, the Faculty of Philosophy - 100 students, the Faculty of Science - 50 students, the Medical School - 217 students, the School of Dental Medicine - 108 students, and the Faculty of Economics and Business - 228 students. The questions in the survey covered several different energy issues, including the present and the future energy resources, the acceptability of different fuel type power plants, the environmental protection and global warming, the radioactivity, the waste issues, as well as reliable information sources. The basic results of survey analysis for nuclear oriented questions are reported in this paper. Although participants expressed high level of formal environmental awareness, their choices and attitudes are in a contradiction to claimed eco-orientation, as well as to the scientific facts. The discrepancies are particularly noticeable in parts of the survey dealing with the nuclear energy and the nuclear power plants. The radioactive waste management, proved to be a potential stumbling-stone for the entire nuclear program. The participants are demonstrating deep lack of knowledge which results in the radioactive waste management becoming the main source of fear from the nuclear technology in general. A very disturbing attitude is a belief that the nuclear energy is non-economic, environmentally unacceptable and operationally unsafe source of energy. Such an attitude

    2008-10-01

    This compendium updates a 2003 literature review of surveys of knowledge and opinions of hydrogen and fuel cell technologies. Its purpose is to ensure that results of comparable surveys are considered in surveys conducted by the U.S. Department of Energy (DOE). Over twice as many studies related to the DOE survey have been published since 2003 than prior to that date. The fact that there have been significantly more studies implies that there have been further demonstration projects and/or increased interest in hydrogen and fuel cell technologies. The primary findings of these 15 new surveys, all of which were conducted in Europe (E) or North America (NA), to the DOE surveys are as follows: 1.Respondents who are more educated are more accepting of hydrogen technologies (NA). 2.Respondents who are more knowledgeable about hydrogen and/or fuel cells are more accepting of hydrogen technologies (E, NA). 3.When asked about issues of trust, respondents generally expressed distrust of the government or political parties but trusted scientists and environmental protection organizations (E). 4.Technical knowledge about hydrogen and fuel cell technologies is low (E, NA). 5.Respondents may express opinions about a technology even when they are lacking in knowledge of that technology (E). 6.Women and men have different priorities when deciding on an automobile purchase (E). 7.Public acceptance to hydrogen is vulnerable to perceptions of decreased safety (E, NA). 8.Public acceptance to hydrogen is vulnerable to perceptions of increased cost (E, NA). The DOE surveys are similar to surveys that examine technical knowledge of hydrogen and fuel cell technologies, although the technical questions are certainly different. The DOE surveys are also similar to the opinion surveys in that they address many of the same issues, such as safety, sources of energy information, or trust. There are many differences between the surveys reviewed in this compendium and the DOE surveys. The

  7. The Development of the STEM Career Interest Survey (STEM-CIS)

    2014-06-01

    Internationally, efforts to increase student interest in science, technology, engineering, and mathematics (STEM) careers have been on the rise. It is often the goal of such efforts that increased interest in STEM careers should stimulate economic growth and enhance innovation. Scientific and educational organizations recommend that efforts to interest students in STEM majors and careers begin at the middle school level, a time when students are developing their own interests and recognizing their academic strengths. These factors have led scholars to call for instruments that effectively measure interest in STEM classes and careers, particularly for middle school students. In response, we leveraged the social cognitive career theory to develop a survey with subscales in science, technology, engineering, and mathematics. In this manuscript, we detail the six stages of development of the STEM Career Interest Survey. To investigate the instrument's reliability and psychometric properties, we administered this 44-item survey to over 1,000 middle school students (grades 6-8) who primarily were in rural, high-poverty districts in the southeastern USA. Confirmatory factor analyses indicate that the STEM-CIS is a strong, single factor instrument and also has four strong, discipline-specific subscales, which allow for the science, technology, engineering, and mathematics subscales to be administered separately or in combination. This instrument should prove helpful in research, evaluation, and professional development to measure STEM career interest in secondary level students.

    To summarize this rather wide-ranging study, let us review the high points. The future practice of thoracic surgery will be increasingly affected by governmental factors and will have even greater technological dimensions. To do this work, we must continue to attract high-caliber individuals, and this is best accomplished by the early and continuing involvement in the educational process of strong role models from our field. These future surgeons must be motivated to do good work and should have high ethical standards as well as maturity and high intelligence. Experienced, involved faculty leading the residents through a broad program that offers graduated assumption of clinical and leadership responsibilities will facilitate the development of mature clinical judgment. Residents must be taught the clinical skills necessary to do all thoracic operations, leaving subspecialization to postresidency fellowships. The educational program should be humane in its demands and collegial in its application. It should incorporate experiences beyond the operating room, including the opportunity to read, think, and interact with local mentors and colleagues from around the country. The requirements of certification should not be so rigid as to preclude the development of different pathways to the same end. Likewise, although the accreditation process must protect the resident from exploitation, it must not be so restrictive that it does not allow for educational innovation and justifiable differences among programs. These are the thoughtful opinions of our colleagues. They deserve serious consideration. PMID:8494460

    workers in subscribing to treatability of childhood autism, while working experience of less than 6 years among the healthcare workers significantly influenced the opinion of the healthcare workers in admitting to believing in the preventability of childhood autism. Conclusion In designing policies and programs to change negative opinions or beliefs of healthcare workers about childhood autism, there is a need for baseline information such as this survey. Changing the negative opinions or beliefs of the healthcare workers about childhood autism should encourage appropriate help-seeking behavior among parents of children with ASD who may be seeking advice or information from the healthcare workers. This would encourage early interventions, which are essential to prognosis of childhood autism.

    Incentive instruments (effluent charges) are theoretically expected to be preferred to direct regulations (individual emission ceilings) by university-employed, theoretically inclined politically right-wing, professional economists living in a market-oriented country, ceteris paribus. Public sector employed, politically left-wing, professional economists living in a country with a long tradition of government involvement prefer the regulatory approach, ceteris paribus. These theoretical hypotheses tend to be supported by a bivariate probit analysis based on a survey of more than 1400 economists in five countries. 22 references, 4 tables.

    Aim: The objective of this survey was to study the level of awareness, current state of knowledge and opinions towards regenerative endodontic treatments amongst the endodontic residents of India. Settings and Design: Questionnaire based survey was designed. Materials and Methods: After approval from the organizing committee of 26th Federation of Operative Dentistry of India and 19th Indian Endodontic Society National conference 2011, 200 copies of the questionnaire were circulated amongst the endodontic residents in conservative dentistry and endodontics at various colleges across the country about regenerative endodontic procedures. The survey included profile of the respondents and consisted of 23 questions about their knowledge, attitude and opinions regarding use of these procedures as part of future dental treatment. Results: The survey showed that half the participants (50.6%) had received continued education in stem cells and/or regenerative dental treatments. The majority of participants were of the opinion (86.6%) that regenerative therapy should be incorporated into dentistry, and most of them (88%) were willing to acquire training in learning this new treatment strategy. The results indicated that half of the participants (52.6%) were already using some type of regenerative therapy in their clinical practice; however, with a majority of these limited to use of membranes, scaffolds or bioactive materials. Conclusions: These results reflect that endodontic residents are optimistic about the use of regenerative endodontic procedures; however, a need for more research and training was felt.

    Following Snyderman and Rothman (1987, 1988), we surveyed expert opinions on the current state of intelligence research. This report examines expert opinions on causes of international differences in student assessment and psychometric IQ test results. Experts were surveyed about the importance of culture, genes, education (quantity and quality), wealth, health, geography, climate, politics, modernization, sampling error, test knowledge, discrimination, test bias, and migration. The importance of these factors was evaluated for diverse countries, regions, and groups including Finland, East Asia, sub-Saharan Africa, Southern Europe, the Arabian-Muslim world, Latin America, Israel, Jews in the West, Roma (gypsies), and Muslim immigrants. Education was rated by N = 71 experts as the most important cause of international ability differences. Genes were rated as the second most relevant factor but also had the highest variability in ratings. Culture, health, wealth, modernization, and politics were the next most important factors, whereas other factors such as geography, climate, test bias, and sampling error were less important. The paper concludes with a discussion of limitations of the survey (e.g., response rates and validity of expert opinions). PMID:27047425

    Full Text Available Problem statement: The Association of Southeast Asian Nations (ASEAN envisioned an integrated regional community by the year 2015, following the European Union model. However, unlike the European Community which was formed after years of discussion at different levels of society, institutions and government, ASEAN was rather quick to conceptualize this initiative, without seeking the feedbacks for the public. Consequently, ASEAN Community initiative has been criticized for being elitist in its policy formulation process and for the lack of public opinions regarding this policy. The study examines how people in three ASEAN countries (Indonesia, Malaysia and Singapore view the concept of community building, especially from the perspective of the obstacles that this initiative is perceived to encounter in its formation. Approach: The study employs public opinion surveys to gather feedback from respondents regarding their opinion of the obstacles towards the establishment of the ASEAN community by the year 2015. The surveys conducted in eleven cities in three ASEAN countries, namely Indonesia (Jakarta, Makassar, Medan, Surabaya and Pontianak, Malaysia (Kuala Lumpur, Penang, Melaka, Johor Bahru and Kota Kinabalu and Singapore. The surveys involved 1256 respondents- 551 from Indonesia, 451 from Malaysia and 294 from Singapore. Results: The study reveals several findings; firstly the low levels of education in several ASEAN countries have been cited as the main factor that hinders regional integration; secondly there has been a lack of initiative to engage the public regarding their opinions on regional integration and thirdly, issues such as lack of economic competitiveness, dependency on develop countries, socio-economic disparity, differences in legal and political systems and technological divide have scored high agreements among respondents-as contributory factors that would possibly slow down regional integration initiatives. Conclusion: The

    The main advantages of online questionnaires are the speed of data collection and cost savings, but response rates are usually low. This study analyzed response rates and associated factors among health professionals in three opinion surveys in the autonomous region of Madrid. The participants, length of the questionnaire and topic differed among the three surveys. The surveys were conducted by using paid Internet software. The institutional e-mail addresses of distinct groups of health professionals were used. Response rates were highest in hospitals (up to 63%) and administrative services and were lowest in primary care (less than 33%). The differences in response rates were analyzed in primary care professionals according to age, sex and professional category and only the association with age was statistically significant. None of the surveys achieved a response rate of 60%. Differences were observed according to workplace, patterns of Internet usage, and interest in the subject.

    A survey about opinions on end-of-life issues of a population represented by 1,171 people in the waiting room of general practitioners' surgeries was conducted in a province of northern Italy. Most subjects did not consider suicide as a reasonable option even in cases of a serious and incurable disease. Moreover, subjects did not consider euthanasia as a possible option either; however, they did express an opposite attitude when considering euthanasia in a third-person perspective. People with a personal history of suicidal behavior appear to present as a different population, overall expressing more open attitudes.

  3. National 2010 survey on the awareness and opinion of the French about geological carbon storage

    International Nuclear Information System (INIS)

    This report presents the results of the 2010 CIRED / TNS Sofres public opinion survey about geological storage of CO2 in France. The first survey, in April 2007, demonstrated a broad consensus for action against climate change. Three years later in March 2010, even a wide support for action remains, the public opinion was marked from the Copenhagen fiasco and the 'climate-gate'. More generally, in a context of global economic crisis, compared to 2007 the economy/environment balance moves back in 2010 towards the former term. Thus, 62% of the French answered that there is a need to act against climate change, that is 17 points less than three years ago. And 67% estimated that 'the priority must go to the protection of the environment' instead of the economy, that is 11 points less. The 2007 survey suggested that 6% of the respondents were able to define correctly geological storage of CO2. The approval rate was 59% at first, but fell to 38% after reading about the risks of the technology. Three years later, the context included emerging CCS projects in France, a (failed) carbon tax proposal and sustained debates on climate change. While CCS has never been a hot topic in the media, it moved from being inexistent to a few specific papers each semesters in important newspapers and some TV / radio air-time. Between 2007 and 2010 the notoriety of CCS increased in France, but the rates of approval mostly stagnated: 57% at first, falling to 37% after the reading on risks. The expression 'stockage geologique du CO2' is now recognized by one third of the French, and about 17% can provide an exact definition. There remain an ambiguity with sequestration in forests, and the mental image of storing CO2 in underground caves or vessels remains widespread. Our study shows a statistically significant positive correlation between more information and a favorable opinion towards geological sequestration. The opinion of respondents is more stable when

The first part addresses the current concerns of French people (main concerns in the present society, with respect to the environment, and risks related to industrial installations). The second part addresses the opinion on expertise (the role and image of experts, diffusion and sharing of scientific expertise, and who should control a hazardous installation). The third part examines the reaction of people in front of 34 different hazardous situations (risks to which people feel being exposed, confidence people have in authorities to protect them, confidence in information on hazards, hierarchy of the 34 situations according to three different aspects, and relationship with installation acceptability). The fourth part addresses the nuclear domain: expectations related to the control of the nuclear risk, fear of a severe accident, benefits and drawbacks of nuclear energy, expertise and credibility of interveners in the nuclear sector. The fifth part addresses the presence of radon in dwellings (awareness of the risk, measures related to the control of radon in dwellings)

    Full Text Available Tourism is a kind of human activity, which has the ability to simultaneously satisfy a wide human needs’ range and develop people’s personality. Adventure tourism term is a type of tourism able to fulfill these types of human needs. The aim of the study was to know the Polish tourists opinion about the adventure tourism in Poland. The study involved 50 people, taking into account their gender, age, education and occupational status. The research tool was a survey questionnaire. The study indicated that it is not a popular form of tourism in Poland. Its proponents, the information about places and facilities derive mainly from the Internet. The most popular forms are trekking, tramping, caves exploration, paintball, windsurfing, bungejumping and rafting. Rather average possibility of practicing the adventure tourism in Poland is associated with multitude barriers, mainly financial investments, lack of free time, as well as fear and general fear of some of its forms.

  6. The current state of radiation education in schools and results of the opinion survey on radiation

    International Nuclear Information System (INIS)

    In 2008, a new guideline about radioactivity was added to the government guidelines for teaching junior high school science. Since then people involved with school education have been trying to spread correct information about radioactivity. On the other hand, people's confusion in the aftermath of the Fukushima Daiichi Nuclear Power Plant accident has clearly shown that people do not know much about radioactivity. Considering the situation, the author conducted an investigation about the current state of radiation education and carried out an opinion survey about radioactivity among adults. The investigation about education showed the following: (1) the nature of radiation, such as its permeability, and its uses were described in the government-approved textbooks; (2) basic knowledge, such as what are radiation effects, were described comprehensively in the supplementary reading recommendations made by the Ministry of Education, Culture, Sports, Science, and Technology; and (3) locale education committees created teaching materials such as guidance to present topics. The opinion survey had questions to judge: (1) current public understanding of radioactivity; (2) the degree of general information that people collected for themselves; (3) the degree of specific knowledge about radioactivity that people had; and (4) people's attitudes toward various problems with radioactivity in the environment. The results suggested that for radiation education the following items are important: (1) to learn that radioactivity exists in people's daily lives and is used safely in various field; (2) to get basic knowledge and better quantitative understanding of such things as radioactivity units, radiation dose and radiation effects; and (3) to acquire practical experience to use the information effectively.

    International Nuclear Information System (INIS)

    As one of nuclear power PA activities, Fuji Atomic Power Group (FAPIG) had held the meeting for its affiliated company's employee to visit the nuclear power station (NPS). Seminar was held on the first day to understand energy in general and basis of nuclear power and then visiting related facilities of NPS for information was made on the 2nd day. Each participant was asked to answer the questionnaire on necessity and safety of nuclear power before opening of seminar and after the visit to NPS. In May 2012 all the past participants were asked to answer the same questionnaire to know change of the opinion toward necessity and safety after 3.11. Respective percentages of pros in necessity and safety were 100% and 76% for past 5 years and 56% and 24% after 3.11. No big sex difference for necessity and large sex difference for safety were also observed, as well as large age difference for necessity and no big age difference for safety. (T. Tanaka)

    2008-09-01

    The 2008/2009 Knowledge and Opinions Survey, conducted for the Department of Energy's Hydrogen Program will measure the levels of awareness and understanding of hydrogen and fuel cell technologies within five target populations: (1) the general public, (2) students, (3) personnel in state and local governments, (4) potential end users of hydrogen fuel and fuel cell technologies in business and industry, and (5) safety and code officials. The ultimate goal of the surveys is a statistically valid, nationally based assessment. Distinct information collections are required for each of the target populations. Each instrument for assessing baseline knowledge is targeted to the corresponding population group. While many questions are identical across all populations, some questions are unique to each respondent group. The biggest data quality limitation of the hydrogen survey data (at least of the general public and student components) will be nonresponse bias. To ensure as high a response rate as possible, various measures will be taken to minimize nonresponse, including automated callbacks, cycling callbacks throughout the weekdays, and availability of Spanish speaking interviewers. Statistical adjustments (i.e., sampling weights) will also be used to account for nonresponse and noncoverage. The primary objective of the data analysis is to estimate the proportions of target population individuals who would respond to the questions in the various possible ways. Data analysis will incorporate necessary adjustments for the sampling design and sampling weights (i.e., probability sampling). Otherwise, however, the analysis will involve standard estimates of proportions of the interviewees responding in various ways to the questions. Sample-weight-adjusted contingency table chi-square tests will also be computed to identify differences between demographic groups The first round of Knowledge and Opinions Surveys was conducted in 2004. Analysis of these surveys produced a

    A prevalence study on non communicable diseases related to nutrition, alcoholism and tabagism is planned in French Polynesia. The methodology used, although complicated, has been successful in insular states of the South Pacific with either traditional or transitional ways of life. Acceptability level of the study in the urban area of Papeete (Tahiti) has been tested by a public opinion poll using the quota method in order to obtain valuable information on feasibility of the project. The public opinion poll showed that 75% of people would participate, 19.5% would be reluctant and 5.5% would hesitate. The good results must be carefully interpreted with regards to the multi-ethnic structure of French Polynesian population, and to the limits of the quota method. PMID:2772362

    Full Text Available Background: Is knowledge regarding the consequences of substance use among adolescents enough to prevent them from initiating and continuing its use, is a question that needs to be clarified further? Objective: To assess the knowledge regarding harm of use and to obtain information about attitudes among high school students. Also, to discover the opinion of substance use held by users. Materials and Methods: This was a population based cross-sectional study conducted in two high schools of West Bengal, India, among 416 students, in classes VIII, IX, and X, with no interventions. Primary outcome measurements were substance use: knowledge regarding harm, attitude, and opinion. Following this proportions and the chi-square test were used for statistical analysis. Results: Out of 416 students, 52 (12.5% used or abused any one of the substances irrespective of time and frequency in lifetime; 26 (15.1 % were among the urban students and 26 (10.7 % were among their rural counterparts. More than two-thirds (73.07% of the respondents expressed a desire to quit substance use and 57.69% had tried to stop. ′Easy availability′ and ′relief from tension′ were the most frequent reasons for continuation of substance use. Level of knowledge on harmfulness of substance use among students was very high (urban - -84.6% and rural - 61.5% and they stated media as the most frequent source of information. Users were successful in influencing their peers into taking up this habit (urban - 15.4% and rural - 26.9%. Conclusions: Inspite of being aware of the harmful effects of substance use, adolescents take up this habit. This requires comprehensive prevention and control programs in schools and the community, targeted toward adolescents and their parents and other family members. Effective measures are required to encourage shaping the attitude of school children toward self-confidence and adequacy, as also to prevent risk behavior among adolescents.

    Objectives To address the uncertainty associated with procuring pharmaceutical products, product listing agreements (PLAs) are increasingly being used to support responsible funding decisions in Canada and elsewhere. These agreements typically involve financial-based rebating initiatives or, less frequently, outcome-based contracts. A qualitative survey was conducted to improve the understanding of outcome-based and more innovative PLAs (IPLAs) based on input from Canadian and international key opinion leaders in the areas of drug manufacturing and reimbursement. Methods Results from a structured literature review were used to inform survey development. Potential participants were invited via email to partake in the survey, which was conducted over phone or in person. Responses were compiled anonymously for review and reporting. Results Twenty-one individuals participated in the survey, including health technology assessment (HTA) key opinion leaders (38%), pharmaceutical industry chief executive officers/vice presidents (29%), ex-payers (19%), and current payers/drug plan managers/HTA (14%). The participants suggested that ~80%–95% of Canadian PLAs are financial-based rather than outcomes-based. They indicated that IPLAs offer important benefits to patients, payers, and manufacturers; however, several challenges limit their use (eg, administrative burden, lack of agreed-upon endpoint). They noted that IPLAs are useful in rapidly evolving therapeutic areas and those associated with high unmet need, a quantifiable endpoint, and/or robust data systems. The Canadian Agency for Drugs and Technologies in Health, the pan-Canadian Pharmaceutical Alliance, and other arms-length organizations could play important roles in identifying uncertainty and endpoints and brokering pan-Canadian PLAs. Industry should work collaboratively with payers to identify uncertainty and develop innovative mechanisms to address it. Conclusion The survey results indicated that while

    Full Text Available Background and Design: There are many problems in dermatology residency training. The purpose of this study was to describe dermatology residents’ opinions about problems and proposals of their solutions of dermatology residency training programs in Turkey. In addition, by means of these estimations to propose efficient and standard curriculum components are aimed. Material and Method: A descriptive pilot study was designed and a questionnaire was prepared to describe the problems and suggestions for the solution in dermatology residency education. The survey was conducted between 20 June 2006 and 09 August 2006. The questions were prepared in accordance with a 1 to 5 Likert-type scale to evaluate the level of importance and sufficiency of the residents’ opinions. Results: Sixty seven (52 female, 15 male residents responded to the survey. Based on the importance evaluation, although clinical-pathological meetings were the most important educational component, all other educational components were also indicated as important. Based on the sufficiency evaluation, the least sufficient educational components were photodermatology/laser therapy training (score, 1,82 of 5,0 and cosmetic dermatology (1,83. Sufficiency levels of educational components such as textbook review, translation and discussion (3,86 journal club (4,04, preparation of seminar (4,03 and allergy training (2,95 were evaluated as sufficient. All other educational components were determined as insufficient. Overall, the greatest discrepancies between the importance and sufficiency for all educational components were observed in cosmetic dermatology education (2,50.Conclusion: This is the first study to assess dermatology residency education based on the residents’ perspectives, in Turkey. These results show the necessity for review and revise of some of the elements and the necessity to prepare a standard curriculum of dermatology residency education. It is appropriate to

    Global research knowledge has accumulated over the past few decades, and there is reasonable evidence for a positive association between Mycobacterium avium spp. paratuberculosis and Crohn's disease in humans, although its role as a human pathogen has not been entirely accepted. For this reason, management of public health risk due to M. paratuberculosis remains an important policy issue in agri-food public health arenas in many countries. Responsible authorities must decide whether existing mitigation strategies are sufficient to prevent or reduce human exposure to M. paratuberculosis. A Web-based questionnaire was administered to topic specialists to elicit empirical knowledge and opinion on the overall public health impact of M. paratuberculosis, the importance of various routes of human exposure to the pathogen, existing mitigation strategies and the need for future strategies. The questionnaire had four sections and consisted of 20 closed and five open questions. Topic specialists believed that M. paratuberculosis is likely a risk to human health (44.8%) and, given the paucity of available evidence, most frequently ranked it as a moderate public health issue (40.1%). A significant correlation was detected between topic specialists' commitment to M. paratuberculosis in terms of the number of years or proportion of work dedicated to this topic, and the likelihood of an extreme answer (high or low) to the above questions. Topic specialists identified contact with ruminants and dairy products as the most likely routes of exposure for humans. There was consensus on exposure routes for ruminants and what commodities to target in mitigation efforts. Described mandatory programmes mainly focused on culling diseased animals and voluntary on-farm prevention programmes. Despite ongoing difficulties in the identification of subclinical infections in animals, the topic specialists largely agreed that further enhancement of on-farm programmes in affected commodities by

    Full Text Available Background: Clinical research in India experienced dramatic changes with series of stringent guidelines introduced by regulatory authorities. These guidelines posed significant challenges for the clinical trial industry. Objective: To assess the perceptions and opinion of Indian Investigators about the new regulatory guidelines. Methods: We developed a survey questionnaire on recent regulatory guidelines which was hosted on a web portal. Seventy-three investigators from India participated in the survey. Results: Central registration of Ethics Committees (ECs was agreed by 90.1% participants, 76.8% participants agreed to compensation of subjects for study related Serious Adverse Events (SAE's. The compulsion to include government sites in clinical trials was not agreed by 49.3% participants while 21.2% agreed to it. Restriction on a number of trials per investigator was agreed by 49.3% of participants while 40.9% disagreed. Participants (50.7% disagreed to the introduction of audio-video (AV recording of informed consent, 36.6% agreed and 12.7% were neutral. Discussion: Participants observed that post central registration; ECs have improved systems with adequate member composition, functional Standard Operating Procedures, and timely approvals. Participants agreed that compensation of study related SAE's would assure subject protection and safety. The introduction of AV consenting was strongly debated sighting sociocultural issues in the implementation of the same. Conclusion: Participants endorsed guidelines pertaining to the central registration of ECs, SAE related compensation. Restrictions on a number of trials per investigator and AV consenting were debated ardently. The response of the survey participants who are clinical trial investigators in India showed general acceptance, effectiveness and anticipated compliance to the new regulatory guidelines.

    2016-01-01

    Introduction: Mosquito-borne infectious diseases such as dengue, chikungunya, and now Zika, pose a public health threat to the US, particularly Florida, the Gulf Coast states, and Hawaii. Recent autochthonous transmission of dengue and chikungunya in Florida, the recent dengue outbreak in Hawaii, and the potential for future local spread of Zika in the US, has led to the consideration of novel approaches to mosquito management. One such novel approach, the release of sterile genetically modified mosquitoes, has been proposed as a possible intervention, and a trial release of GM mosquitoes is being considered in one Florida community. However, this proposal has been controversial. The objective of this research was to increase understanding of community knowledge, attitudes, and beliefs regarding mosquito control and GM mosquitoes.   Methods: An 18-question self-administered survey was mailed to all households in the identified Key West, Florida neighborhood where a GM mosquito trial has been proposed. This survey was fielded between July 20, 2015 and November 1, 2015. The main outcome variable was opposition to the use of GM mosquitoes. Measures included demographic information and opinions on mosquitoes, mosquito control, and vector-borne diseases.   Results: A majority of survey respondents did not support use of GM mosquitoes as a mosquito control method. Discussion: Reasons for opposition included general fears about possible harmful impacts of this intervention, specific worries about human and animal health impacts from the GM mosquitoes, and environmental concerns about potential negative effects on the ecosystem. Residents were more likely to oppose GM mosquito use if they had a low perception of the potential risks posed by diseases like dengue and chikungunya, if they were female, and if they were less concerned about the need to control mosquitoes in general. These findings suggest a need for new approaches to risk communication, including

    Full Text Available Objectives. Level 1 evidence supports the use of neoadjuvant chemotherapy (NAC to improve overall survival in muscle invasive bladder cancer; however utilization rates remain low. The aims of our study were to determine factors associated with NAC use, to more clearly define reasons for low utilization, and to determine the current rate of NAC use among urologic oncologists. Materials and Methods. Active members of the Society for Urologic Oncology were provided a 20-question survey. Descriptive statistical analysis was conducted for each question and univariate analysis was performed. Results. We achieved a response rate of 21%. Clinical T3/T4 disease was the most often selected reason for recommending NAC (87%. Concerns with recommending NAC were age and comorbidities (54% followed by delay in surgery (35%. An association was identified between urologic oncologists who discussed NAC with >90% of their patients and medical oncologists “always” recommending NAC (P=0.0009. NAC utilization rate was between 30 and 57%. Conclusions. Amongst this highly specialized group of respondents, clinical T3-T4 disease was the most common reason for implementation of NAC. Respondents who frequently discussed NAC were more likely to report their medical oncologist always recommending NAC. Reported NAC use was higher in this surveyed group (30–57% compared with recently published rates.

    New technological developments affect almost every sector of our daily lives, including the healthcare sector. We evaluated how connected health applications, subsumed as eHealth and telemedicine, are perceived in relation to socio-demographic characteristics. The current cross-sectional, online survey collected self-reported data from a non-probability convenience sample of 562 Austrian adults (58.9% females). The concept of eHealth and telemedicine was poorly established among the study population. While most participants already used mobile devices, they expressed a quite low desirability of using various telemedicine applications in the future. Study participants perceived that the most important overall benefits for implementing connected health technology were better quality of healthcare, location-independent access to healthcare services, and better quality of life. The respective three top-ranked overall barriers were data security, lack of acceptance by doctors, and lack of technical prerequisites. With regard to aging societies, healthcare providers, and users alike could take advantage of inexpensive, consumer-oriented connected health solutions that address individual needs of specific target groups. The present survey identified issues relevant for successful implementation of ICT-based healthcare solutions, providing a compilation of several areas requiring further in-depth research.

    Much has been written about interventions to improve the nursing work environment, yet little is known about their effectiveness. A Delphi survey of nurse experts was conducted to explore perceptions about workplace interventions in terms of feasibility and likelihood of positive impact on nurse outcomes such as job satisfaction and nurse retention. The interventions that received the highest ratings for likelihood of positive impact included: bedside handover to improve communication at shift report and promote patient-centred care; training program for nurses in dealing with violent or aggressive behaviour; development of charge nurse leadership team; training program focused on creating peer-supportive atmospheres and group cohesion; and schedule that recognizes work balance and family demands. The overall findings are consistent with the literature that highlights the importance of communication and teamwork, nurse health and safety, staffing and scheduling practices, professional development and leadership and mentorship. Nursing researchers and decision-makers should work in collaboration to implement and evaluate interventions for promoting practice environments characterized by effective communication and teamwork, professional growth and adequate support for the health and well-being of nurses.

    Full Text Available Abstract Background Assisted dying has wide support among the general population but there is evidence that those providing care for the dying may be less supportive. Senior doctors would be involved in implementing the proposed change in the law. We aimed to measure support for legalising physician assisted dying in a representative sample of senior doctors in England and Wales, and to assess any association between doctors' characteristics and level of support for a change in the law. Methods We conducted a postal survey of 1000 consultants and general practitioners randomly selected from a commercially available database. The main outcome of interest was level of agreement with any change in the law to allow physician assisted suicide. Results The corrected participation rate was 50%. We analysed 372 questionnaires. Respondents' views were divided: 39% were in favour of a change to the law to allow assisted suicide, 49% opposed a change and 12% neither agreed nor disagreed. Doctors who reported caring for the dying were less likely to support a change in the law. Religious belief was also associated with opposition. Gender, specialty and years in post had no significant effect. Conclusion More senior doctors in England and Wales oppose any step towards the legalisation of assisted dying than support this. Doctors who care for the dying were more opposed. This has implications for the ease of implementation of recently proposed legislation.

    Full Text Available Objective: Scalp cooling (SC is applied to reduce chemotherapy-induced alopecia (CIA. The aim of this study was to investigate patients′ familiarity and opinions and oncological professionals′ attitude and knowledge about SC in the Netherlands. Methods: Ex breast cancer patients, nurses and medical oncologists (MDs from SC and non-SC hospitals filled out questionnaires. Results: The majority of MDs and nurses were satisfied with the results of SC, as were SC patients. Over 33% of MDs and nurses perceived their knowledge level insufficient to inform patients about effectiveness, which was over 43% for information about safety. MDs main reason to not apply SC was doubt about effectiveness and safety. Nurses generally offered SC to a minority of eligible patients. Patients were frequently unfamiliar with SC before diagnosis. Seventy percent of SC patients with insufficient results (20/52 reported to mind it very much. With expected success rates of 35% and 50%, respectively, 36% and 54% of patients would use SC again. Conclusion: Room for improvement has been shown for both patients′ familiarity and oncological professionals′ knowledge about SC. Sharing knowledge about results, safety and patients′ experiences will improve patient counseling and SC availability. The results of this survey led to the development of a national standard on CIA and SC.

    Full Text Available Abstract Background This study was completed as part of a project for the Quality Assurance Agency on the enhancement theme of 'Research teaching linkages: enhancing graduate attributes' in the disciplines of Medicine, Dentistry and Veterinary Medicine. The aims of this investigation were to elucidate a list of desirable research related graduate attributes for the disciplines of Medicine, Dentistry and Veterinary Medicine and provide evidence as to how they could be covered within such curricula. Methods Semi structured interviews, symposium breakout sessions and conference workshops were used to define and rank attributes suggested by curricula design experts from the three disciplines. Students graduating from a BSc Medical Science degree program were surveyed to determine how well they felt the curriculum and associated final year project equipped them with the identified attributes. Results A list of seven high level attributes which were desirable in graduates wishing to pursue either a professional or research career were identified. 105 students reported that a final year project was particularly effective at developing an understanding of the need to have an inquiring mind and critical appraisal skills whilst other components of their degree course covered team working skills, core knowledge and an understanding of ethics and governance. Conclusion This study identified desirable attributes from graduates from medical, dental and veterinary degree programs and provides evidence to support the case for student projects helping to achieve both clinical and research related graduate attributes in medical undergraduates. The project also provides a focus for debate amongst those involved in curriculum design as to whether the attributes identified are those desirable in their graduates and to examine their current curriculum to determine coverage.

    Chronic rhinosinusitis (CRS) is a very prevalent inflammatory disease. Treatments vary in different countries. In the present study, we explored the approaches of physicians in 50 countries. In this cross-sectional study, a rhinosinusitis survey (RSS) was completed by Honorary and Corresponding Members (otorhinolaryngologists) of the Italian Society of Rhinology. In 79.1 % of the 50 countries, the proportion of patients suffering from CRS was 15 %. Nasal symptoms were more intense in winter (46 % of countries), and spring and autumn (22 %). The most common symptoms were nasal obstruction (86 %), postnasal drip (82 %) and headache (52 %). The most common investigative modalities in the assessment of CRS are paranasal sinus CT, fiberoptic endoscopy, and anterior rhinoscopy. CRS patients were principally treated by otorhinolaryngologists (70 %). Medical treatments included nasal corticosteroids (90 %), nasal washes (68 %), and nasal decongestants (32 %). In 88 % of countries, more than 50 %, or "about 50 %", of all patients reported subjective symptom improvement after treatment. In most of the countries, surgery was required by 20-35 % of all CRS patients. During post-surgery follow-up, nasal washes (90 %), nasal corticosteroids (76 %), and systemic antibiotics (32 %) were prescribed. In 20-40 % of all patients, CRS was associated with nasal polyps. In such patients, the medical treatment options were nasal corticosteroids (90 %), systemic corticosteroids (50 %), nasal washes (46 %), and systemic antibiotics (34 %). Treatment of CRS patients varies in different countries. Paranasal sinus CT is the most common investigative modality in the assessment of CRS, and nasal corticosteroids are the first-line treatment, in the absence or presence of nasal polyps.

    The U.S. Department of Energy (DOE) Hydrogen Program focuses on overcoming critical barriers to the widespread use of hydrogen fuel cell technology. The transition to a new, hydrogen-based energy economy requires an educated human infrastructure. With this in mind, the DOE Hydrogen Program conducted statistical surveys to measure and establish baselines for understanding and awareness about hydrogen, fuel cells, and a hydrogen economy. The baseline data will serve as a reference in designing an education program, and it will be used in comparisons with future survey results (2008 and 2011) to measure changes in understanding and awareness. Scientific sampling was used to survey four populations: (1) the general public, ages 18 and over; (2) students, ages 12-17; (3) state and local government officials; and (4) potential large-scale hydrogen users. It was decided that the survey design should include about 1,000 individuals in each of the general public and student categories, about 250 state and local officials, and almost 100 large-scale end users. The survey questions were designed to accomplish specific objectives. Technical questions measured technical understanding and awareness of hydrogen technology. Opinion questions measured attitudes about safety, cost, the environment, and convenience, as well as the likelihood of future applications of hydrogen technology. For most of the questions, "I don't know" or "I have no opinion" were acceptable answers. Questions about information sources assessed how energy technology information is received. The General Public and Student Survey samples were selected by random digit dialing. Potential large-scale end users were selected by random sampling. The State and Local Government Survey was of the entire targeted population of government officials (not a random sample). All four surveys were administered by computer-assisted telephone interviewing (CATI). For each population, the length of the survey was less than

  11. Public opinion and nuclear waste

    International Nuclear Information System (INIS)

    Surveys and opinion polls regularly reinforce the belief that nuclear waste is one of the general public greatest fears. Their results reflect the way this theme is handled by the media, often in a negative or controversial light. Closer examination of these surveys, however, reveals that the apparently delicate situation of nuclear waste in public opinion deserves a more subtle, qualified approach. (author)

  12. Informing decision making in agricultural greenhouse gas mitigation policy: A Best–Worst Scaling survey of expert and farmer opinion in the sheep industry

    International Nuclear Information System (INIS)

    Highlights: ► Effectiveness and practicality of greenhouse gas mitigation measures are assessed. ► Best–Worst Scaling surveys are used to elicit expert and sheep farmer opinion. ► Effective and practical measures are priority candidates for policy inclusion. ► Support mechanisms may be needed to deliver effective, low practicality measures. ► Variation in farmers’ perceptions of practicality holds implications for policy delivery. -- Abstract: Policy decision making for agricultural greenhouse gas mitigation is hindered by scientific uncertainty regarding the effectiveness of mitigation measures. Successful on-farm adoption of measures is contingent upon farmer perception of the relative practicality of implementing the measure and associated incentives and advice. In the absence of a comprehensive evidence base we utilised Best–Worst Scaling, a discrete choice survey method, to elicit expert and farmer opinion on the relative effectiveness and practicality of mitigation measures to reduce greenhouse gas emissions from sheep production systems. The method enabled individual mitigation measures to be ranked on a ratio scale of effectiveness (expert opinion) and practicality (farmer opinion). Six measures were identified as possessing the combined qualities of effectiveness and practicality and are considered priority candidates for policy promotion. The overall preferred measure was the use of legumes in pasture reseed mixes. Estimation and analysis of the distribution of individual respondent scores revealed heterogeneity in farmers’ perceptions of practicality, suggesting that flexible policies are required to enable farmers to select mitigation measures most suited to their farm type and locality. Practical measures with below average effectiveness may be widely adopted with limited regulation, incentivisation or advice, whilst some highly effective measures with lower practicality are likely to present greater obstacles to adoption

    While opinion leadership has been recognized as important in tourism, there has been very little empirical research investigating the phenomenon. Given new developments in social media technologies, it is especially important to understand whether travel opinion leadership and seeking are drivers...... of specific social media perceptions and behaviours. Based on an online survey of US online travellers, this paper seeks to identify travel opinion leaders and seekers and their characteristics. Further, the research conducted investigated linkages between travel opinion leadership/seeking and travel social...... media use. The findings suggest that travel opinion leadership and seeking are distinct but connected. Both opinion leaders and seekers are technology savvy, young, educated, involved in travel planning and engaged in social media use for travel. What distinguishes opinion leaders is their greater...

    2007-01-01

    Objectives To assess French district nurses' opinions towards euthanasia and to study factors associated with these opinions, with emphasis on attitudes towards terminal patients. Design and setting An anonymous telephone survey carried out in 2005 among a national random sample of French district nurses. Participants District nurses currently delivering home care who have at least 1 year of professional experience. Of 803 district nurses contacted, 602 agreed to participate (response rate 75%). Main outcome measures Opinion towards the legalisation of euthanasia (on a five‐point Likert scale from “strongly agree” to “strongly disagree”), attitudes towards terminal patients (discussing end‐of‐life issues with them, considering they should be told their prognosis, valuing the role of advance directives and surrogates). Results Overall, 65% of the 602 nurses favoured legalising euthanasia. Regarding associated factors, this proportion was higher among those who discuss end‐of‐life issues with terminal patients (70%), who consider competent patients should always be told their prognosis (81%) and who value the role of advance directives and surrogates in end‐of‐life decision‐making for incompetent patients (68% and 77% respectively). Women and older nurses were less likely to favour legalising euthanasia, as were those who believed in a god who masters their destiny. Conclusions French nurses are more in favour of legalising euthanasia than French physicians; these two populations contrast greatly in the factors associated with this support. Further research is needed to investigate how and to what extent such attitudes may affect nursing practice and emotional well‐being in the specific context of end‐of‐life home care. PMID:18055901

    Grabowski, Andrzej

    2016-01-01

    On the basis of the experimental data concerning interactions between humans the process of Ising-based model of opinion formation in a social network was investigated. In the paper the data concerning human social activity, i.e. frequency and duration time of interpersonal interactions as well as age correlations - homophily are presented in comparison to base line homogeneous, static and uniform mixing. It is known from previous studies that number of contact and average age of nearest neighbors are highly correlated with age of an individual. Such real, assortative patterns usually speed up processes (like epidemic spread) on the networks, but here it only plays a role for small social temperature values (by reducing `freezing by heating' effect). A real structure of contacts affects processes in many various studies in different way, however here it causes stronger (dynamic) and smoother (durations) susceptibility on external field. Moreover, our research shows that the cross interactions between contact ...

  4. Public opinion on lay participation in the criminal justice system of the Netherlands Some tentative findings from a panel survey

    Directory of Open Access Journals (Sweden)

    2007-12-01

    Full Text Available In the Netherlands the recent debate on lay involvement in the administration of criminal justice was initiated by politicians who maintain that the public favours such involvement. The response of the judiciary and legal academics to these politicians has been fairly defensive. They have pointed in particular to the dangers of the punitive character of the vox populi and rejected the idea. As a result, the debate on lay involvement has quickly become a black and white issue. This article presents the findings of a recent research of the Netherlands Council for the Judiciary and the Research and Documentation Centre of the Dutch Ministry of Justice regarding the opinion of the public on different kinds of lay involvement under different conditions. This research shows that both the position of the politicians that favour lay involvement in the administration of criminal justice and the position of the judiciary and legal academics that reject lay involvement are to a relatively large degree unrepresentative of the wishes and views of the public.

This study reviews the current status of, and describes future directions, in the field of BCI games. To this end, we conducted a literature search and found that BCI control paradigms using electroencephalographic signals (motor imagery, P300, steady state visual evoked potential and passive approach reading mental state have been the primary focus of research. We also conducted a survey of nearly three hundred participants that included researchers, game developers and users around the world. From this survey, we found that all three groups (researchers, developers and users agreed on the significant influence and applicability of BCI and BCI games, and they all selected prostheses, rehabilitation and games as the most promising BCI applications. User and developer groups tended to give low priority to passive BCI and the whole head sensor array. Developers gave higher priorities to “the easiness of playing” and the “development platform” as important elements for BCI games and the market. Based on our assessment, we discuss the critical point at which BCI games will be able to progress from their current stage to widespread marketing to consumers. In conclusion, we propose three critical elements important for expansion of the BCI game market: standards, gameplay and appropriate integration.

    The U.S. Department of Energy (DOE) Fuel Cell Technologies Program (FCT) conducts comprehensive efforts to enable the widespread commercialization of fuel cells in diverse sectors of the economy - with emphasis on applications that will most effectively strengthen our nation's energy security and improve our stewardship of the environment. Expanding the use of fuel cells requires a sustained education effort to lay the foundation for future commercial market introduction. The FCT education subprogram seeks to facilitate fuel cell demonstrations and support future commercialization by providing technically accurate and objective information to key target audiences both directly and indirectly involved in the use of fuel cells today. These key target audiences include a public that is familiar and comfortable with using a new fuel, state and local government officials who understand the near-term realities and long-term potential of the technology, an educated business and industry component, and trained safety and codes officials. With this in mind, the DOE FCT program established an education key activity to address the training and informational needs of target audiences that have a role in the near-term transition and the long-term development of a hydrogen economy. Whether or not changes can be attributed to the program, designing and maintaining an effective education program entails measuring baseline awareness and periodically measuring what has been learned. The purpose of this report is to document the data and results of statistical surveys undertaken in 2008 and 2009 to measure and establish changes in understanding and awareness about hydrogen and fuel cell technologies since a baseline survey was conducted in 2004. This report is essentially a data book, a digest of the survey data and an exposition of changes in knowledge of and opinions about hydrogen and fuel cell technology since 2004. Many conclusions can be made from the survey data. However

The participants represented thegeneral Japanese population. We used this data to carry out multivariate analysis. The main outcomemeasures were adjusted odds ratios and 95% confidence intervals from logistic regression modelsfor factors including the effect of pregnancy risk perception on the attitude toward gestationalsurrogacy.Results: In this survey, 3412 participants responded (response rate of 68.2%. With regard to theattitude towards gestational surrogacy, 54.0% of the respondents approved of it, and 29.7% statedthat they were undecided. The perception of a high level of risk concerning ectopic pregnancy,threatened miscarriage or premature birth, and pregnancy-induced hypertension influencedthe participants’ attitudes towards gestational surrogacy. Moreover, this perception of risk alsocontributed to a disapproval of the technique.Conclusion: Our findings suggest that a person who understands the risks associated with pregnancymight clearly express their disapproval of gestational surrogacy.

    This opinion-based article aims to highlight the worrying decline in support for dental public health as a specialty. Not only is this specialty important for its role in commissioning services, it is crucial for the identification of vulnerable groups in society and ensuring dental services are acceptable and assessable for these populations. Dental public health also addresses the social determinants of health in its approach, acknowledging the impact of these in perpetuating inequalities and looking for multisectoral approaches to their management. This article also looks at the lack of appreciation for these determinants in dental foundation training and how a change in the structure of the programme could both address this and the current shortage of places.

  17. Abundant raw material for cis-regulatory evolution in humans

    Science.gov (United States)

    Rockman, Matthew V.; Wray, Gregory A.

    2002-01-01

    Changes in gene expression and regulation--due in particular to the evolution of cis-regulatory DNA sequences--may underlie many evolutionary changes in phenotypes, yet little is known about the distribution of such variation in populations. We present in this study the first survey of experimentally validated functional cis-regulatory polymorphism. These data are derived from more than 140 polymorphisms involved in the regulation of 107 genes in Homo sapiens, the eukaryote species with the most available data. We find that functional cis-regulatory variation is widespread in the human genome and that the consequent variation in gene expression is twofold or greater for 63% of the genes surveyed. Transcription factor-DNA interactions are highly polymorphic, and regulatory interactions have been gained and lost within human populations. On average, humans are heterozygous at more functional cis-regulatory sites (>16,000) than at amino acid positions (human phenotypic variation.

    2016-01-01

    Solicited public opinion surveys reach a limited subpopulation of willing participants and are expensive to conduct, leading to poor time resolution and a restricted pool of expert-chosen survey topics. In this study, we demonstrate that unsolicited public opinion polling through sentiment analysis applied to Twitter correlates well with a range of traditional measures, and has predictive power for issues of global importance. We also examine Twitter's potential to canvas topics seldom surveyed, including ideas, personal feelings, and perceptions of commercial enterprises. Two of our major observations are that appropriately filtered Twitter sentiment (1) predicts President Obama's job approval three months in advance, and (2) correlates well with surveyed consumer sentiment. To make possible a full examination of our work and to enable others' research, we make public over 10,000 data sets, each a seven-year series of daily word counts for tweets containing a frequently used search term.

    With the rapid development of Internet, Internet users are more inclined to express their concerns, views for the interest topics and interact with each other in blog sites, ecommerce sites and other places by means of publishing articles, reviews and other means. And a lot of valuable knowledge mined from the user-generated-content can be applied to many fields. However, the contents which are uninvited, unrelated to the topics (e. G. Advertising) or related to the topics but false in the user-generated-content have serious impact on the results of mining, and produce bad results such as misleading internet users and wasting resources and so on. Therefore, the research of opinion spam which is an important part of opinion mining research is receiving unprecedented attention. This paper summarized the research of opinion spam from the features of the opinion spam and the detection method for the opinion spam.%随着互联网的快速发展,互联网用户更倾向于在博客、购物网站等场所借助于发表文章、评论等手段表达自己对感兴趣话题的关注、意见和相互交流.对这些用户生成内容进行挖掘可以得到很多宝贵的可应用于很多领域的知识,但其中存在的不请自来、与话题无关(广告等)或虽与话题相关但是虚假性的内容严重影响了挖掘的效果,并产生了误导用户、浪费资源等不良影响.因此,作为意见挖掘研究工作重要组成部分的垃圾意见研究工作开始得到空前的重视.从垃圾意见特征、垃圾意见检测方法两个方面对目前垃圾意见的研究状况进行了综述.

    Full Text Available Nonsteroidal anti-inflammatory drugs (NSAIDs are able to effectively control the major symptoms of rheumatic diseases and widely used in real clinical practice. However, they may cause serious gastrointestinal (GI and cardiovascular (CV events. The prevention of these events is based on the estimation of whether risk factors (RFs are present.Objective: to estimate the presence of RFs in patients needing NSAIDs.Subjects and methods. A cross-sectional epidemiological survey was performed, during which 2021 physicians from 9 CIS countries questioned for 2 weeks at least 10 patients needing NSAIDs. The inclusion criterion was severe musculoskeletal pain (>40 mm on a 100-mm visual analogue scale (VAS or use of NSAIDs at the examination. Data were obtained on 21,185 patients (57.5% women and 42.5% men (mean age 50.5±14.1 years who had predominantly dorsalgia (56.6% and osteoarthritis (23.5%. The mean pain value was 62.2±25.2 mm.Results. 1.7, 11.3, and 25.3% of patients had history of gastrointestinal bleeding, ulcer, or dyspepsia, respectively; people over 65 years of age constituted 16.8%; those who took low-dose aspirin (LDA – 20.0%. The total number of patients at high risk for GI events was 29.0%. There were also common CV RFs: myocardial infarction or stroke (7.8%, coronary heart disease (17.8%, hypertension (37.7%, and diabetes mellitus (8.1%. The total number of patients at high risk for CV events (without SCOR assessment was 23.0%. Many high-risk patients who has already used NSAIDs received no effective prevention. Thus, 62.2% of the patients at high GI risk took gastroprotective drugs; 53.2% of those at high CV risk used LDA.Conclusion. A large number of patients needing active analgesic therapy have a serious risk for drug-induced complications. This limits the possibility of using NSAIDs and determines the need for effective prevention or use of alternative methods for analgesia.

  12. Reinforcement in opinion dynamics

    Science.gov (United States)

    Volovik, Daniel

    I consider the evolution and acceptance of a new opinion in a population of unaware agents by using physics-based models of contagion spread. These models rely upon agent-based dynamics, in which an agent changes opinion by interactions with neighbors according to specific interactions. Most of these models have the feature that only a single input is required to change the opinion of an agent --- an agent has no commitment to its current opinion and accepts a new idea at the slightest provocation. These single-input models fail to account for people's confidence in their own beliefs. Thus I study the concept of social reinforcement --- that an agent adopts a new opinion only after multiple reinforcing prompts. Building on single-input models, I introduce two models of opinion spreading that incorporate a social reinforcement mechanism. (a) In the irreversible innovation and in the transient fad spreading models, a development is initially known only to a small portion of the population and subsequently spreads. An individual requires M > 1 interactions with an adopter before adopting the development. The ultimate extent of a transient fad depends critically on the characteristic time the fad keeps the attention of an adopting agent. (b) In the confident voter model, a voter can be in one of two opinion states and can additionally have two levels of commitment to an opinion: confident and vacillating. Upon interacting with an agent of a different opinion, a confident voter becomes less committed, or vacillating, but does not change opinion. However, a vacillating agent changes opinion by interacting with an agent of a different opinion. In two dimensions, the distribution of consensus times is characterized by two distinct times one that scales linearly with N and another that appears to scale as N 3/2. The longer time arises from configurations that fall into long-lived states that consist of multiple single-opinion stripes before consensus is reached.

  13. Survival of extreme opinions

    Hsu, Jiann-wien; Huang, Ding-wei

    2009-12-01

    We study the survival of extreme opinions in various processes of consensus formation. All the opinions are treated equally and subjected to the same rules of changing. We investigate three typical models to reach a consensus in each case: (A) personal influence, (B) influence from surroundings, and (C) influence to surroundings. Starting with uniformly distributed random opinions, our calculated results show that the extreme opinions can survive in both models (A) and (B), but not in model (C). We obtain a conclusion that both personal influence and passive adaptation to the environment are not sufficient enough to eradicate all the extreme opinions. Only the active persuasion to change the surroundings eliminates the extreme opinions completely.

    The objective of this study was to determine the knowledge and attitudes of practicing Nigerian lawyers towards issues relating to reproductive health and reproductive rights, and their opinions about abortion law reform. It was a population- based study which consisted of interviews with practicing lawyers in north-east Nigeria. The results showed poor knowledge of issues related to reproductive health and reproductive rights among the lawyers. However, the majority (56.9%) disagreed that a woman can practice family planning without the consent of her husband. The prevalence of contraceptive use among the lawyers was low and attitude to abortion law not satisfactory. Only few lawyers (22.4%) supported safe abortion in cases of failed contraception. We conclude that reproductive health advocates must target legal professionals with a view to educating them on issues relating to sexual and reproductive health and rights. Lawyers in Nigeria should undergo capacity building in reproductive health laws and be encouraged to specialize in reproductive rights protection as obtainable in other developed countries.

    The normal vibrational calculation was carried out on cis-polyacetylene(PA) and its model compound, cis, trans-2, 4-hexadiene. Based on the observed IR and Raman frequencies, force constants relevant to the cos-structure were refined. Finally a force field common for cis-PA, trans-PA and three model moleculaes was obtained. The observed spectra of cis-PA were theoreticallyassigned and the similarities and differences between the cis-and trans- conjugate systems were discussed on the basis of normal coordinate calculation.

    2016-01-01

    Objectives A survey of a population-based sample of U.S adults was conducted to measure their attitudes about, and inform the design of the Precision Medicine Initiative’s planned national cohort study. Methods An online survey was conducted by GfK between May and June of 2015. The influence of different consent models on willingness to share data was examined by randomizing participants to one of eight consent scenarios. Results Of 4,777 people invited to take the survey, 2,706 responded and 2,601 (54% response rate) provided valid responses. Most respondents (79%) supported the proposed study, and 54% said they would definitely or probably participate if asked. Support for and willingness to participate in the study varied little among demographic groups; younger respondents, LGBT respondents, and those with more years of education were significantly more likely to take part if asked. The most important study incentive that the survey asked about was learning about one’s own health information. Willingness to share data and samples under broad, study-by-study, menu and dynamic consent models was similar when a statement about transparency was included in the consent scenarios. Respondents were generally interested in taking part in several governance functions of the cohort study. Conclusions A large majority of the U.S. adults who responded to the survey supported a large national cohort study. Levels of support for the study and willingness to participate were both consistent across most demographic groups. The opportunity to learn health information about one’s self from the study appears to be a strong motivation to participate. PMID:27532667

  3. The pros and cons about restarting and awareness about nuclear power generation. Further findings from INSS's analysis of the opinion survey answers

    International Nuclear Information System (INIS)

    In this paper, the pros and cons and the awareness of their background on the restart of nuclear power plants (NPPs) were analyzed based on the data of opinion polls conducted by news organizations and INSS. The results were as follows: (1) Although opposition to restart has been nearly 60% in the case when the question has only 2 choices of pros and cons, the 60% includes many people who “cannot say either way”. (2) For approval of restarting, it is necessary to have the attitude to tolerate the use of nuclear power generation (NPG), and it is extremely important that people think “safety has been confirmed,” but it does not seem to be enough reason to hesitate in the restart. (3) From the open-ended question about the influences of long-term shutdown of NPPs on the respondents and Japanese society, 50% of the respondents said there was no influence. 20% said they felt safe or easy because no accident could occur. Only 20% described economic influence, such as a real increase in electricity cost, especially among men or the people who were in favor of restarting. (4) When the above-described influences, people's recognition of the utility of NPG (or thinking about the problems that occur when reducing NPG) and people's criteria for selecting an electric power generation method were organized in terms of the 3Es (Energy security, Economic efficiency, Environment), there was quite a difference from the idea of energy policy that emphasizes a good balance among these 3Es. People's recognition of the utility of NPG has been declining. This was considered to be the reason that neither the present influences nor the importance of the invisible influence at a macro-level had been recognized. For restarting to be supported by many people, there is a need for appropriate information about not only the safety, but also the importance from the viewpoints of the 3Es and the benefits of NPG in the 3Es.

  6. Lessons learned about the information activities related to local hearings in Finland, based on a university study, and the latest opinion survey results from autumn 1992

    International Nuclear Information System (INIS)

    This paper considers the results of two studies by the University of Tampere, financed by power companies (IVO, TVO and PEVO) in Finland. The first one deals with information events arranged during the application process for the fifth nuclear power plant unit. The results demonstrate both the validity of some well-known information theories and the power of local media compared to booklets issued by power companies. The second study reported is the newest part of a longitudinal energy attitude survey. The results found may hold true even in other countries, due to the general symbolic values related to energy questions. Perhaps the most amazing result is the stability of attitudes. Other findings are discussed and evaluated, too. (author)

The experience of applicants (sponsors, legal representatives of sponsors in the EU and persons or organizations authorized by the sponsors to make the application, respectively in terms of interactions with the ethics committees in Germany has been positive overall, especially with respect to ethics committee adherence to the statutory timelines applicable for review of requests. However, inconsistencies between ethics committees exist in terms of the form and content of the requirements for application documents and their evaluation.With the objective of further improving both the quality of applications and the evaluation of those applications by ethics committees, a survey among members of the German Association of Research-Based Pharmaceutical Companies (VFA was conducted from January to April 2008. Based on reasoned opinions issued by the respective ethics committee in charge of the coordinating principal investigator (coordinating ethics committee, the type and frequency of formal and content-related objections to applications according to § 7 of the German Good Clinical Practice (GCP Regulation were systematically documented, and qualitative and quantitative analyses performed. 21 out of 44 members of the VFA participated in the survey. 288 applications for Phase I–IV studies submitted between January and December 2007 to 40 ethics committees were evaluated.This survey shows that about one in six applications is incomplete and has formal and/or content objections, respectively, especially those that pertain to documents demonstrating the qualification of the investigator and/or suitability of the facilities.

    2014-01-01

    Although forms of address are widely used in textual and other types of disclosure,empirical evidence of their effects is rare.China provides a unique setting in which to test the economic consequences of the forms of address used in audit reports.From 2003 to 2011,about 60%of auditors surveyed addressed their clients by their real names in audit opinions,while the others used honorifics.Based on a sample of Chinese audit opinions,I report the following findings.First,the announcement of an audit opinion that uses the client’s real name elicits a greater market response than the announcement of an opinion featuring an honorific form of address.Second,the effects of real-name forms of address are stronger in firms with weak board governance.Third,the association between audit fees and audit risk factors,such as loss-making,is stronger in firms that are addressed by their real names in audit reports.I conclude from these findings that the forms of address used in audit opinions may reveal private information on audit quality.The results of this study are consistent with the power-solidarity effect described by sociolinguists.

    2016-03-01

    On 1 January 2012, conventional cages for laying hens were banned in the European Union (EU); all egg farmers must now use alternative hen housing systems. In total, 218 Flemish egg farmers were surveyed in 2013 to 2014 regarding which housing systems they currently use, their degree of satisfaction with the system, and how they experienced the transition from conventional cages to an alternative system. The response rate was 58.3% (127 respondents). Of these, 43 (33.9%) were no longer active as an egg farmer, mainly due to the ban on conventional cages. The respondents who were active as egg farmers both before and after the transition (84, 66.1%) mainly judged the ban as negative for their own finances and for the competitive position of the Belgian egg industry, but were neutral or positive regarding the general consequences for their own business. Most respondents' hens were housed in either aviary systems (47.7%) or in alternative cage systems (38.2%). When choosing a new system, the fit into the farm and consumer demand were the most important factors. Consumer demand was the main reason for choosing a system with free-range access. In general, egg farmers were satisfied with the system they chose, although this differs between systems. When asked to compare the alternative systems to conventional cages, alternatives were judged to be better for hen welfare and consumer demand, but similar or worse for all other aspects, especially labor. Egg farmers previously using conventional cages judged alternative systems more negatively than those who had no prior experience with conventional cages. Farmers who had experience with free-range systems judged these more positively than those without this experience, e.g., for egg consumer demand, profitability, and hen welfare. These results can possibly be extrapolated to other EU countries in which conventional cages were the most common housing system until 2012, and lessons can be drawn from the farmers' experiences

Egg farmers previously using conventional cages judged alternative systems more negatively than those who had no prior experience with conventional cages. Farmers who had experience with free-range systems judged these more positively than those without this experience, e.g., for egg consumer demand, profitability, and hen welfare. These results can possibly be extrapolated to other EU countries in which conventional cages were the most common housing system until 2012, and lessons can be drawn from the farmers' experiences

  15. Anisotropic opinion dynamics

    We consider the process of opinion formation in a society of interacting agents, where there is a set B of socially accepted rules. In this scenario, we observed that agents, represented by simple feed-forward, adaptive neural networks, may have a conservative attitude (mostly in agreement with B ) or liberal attitude (mostly in agreement with neighboring agents) depending on how much their opinions are influenced by their peers. The topology of the network representing the interaction of the society's members is determined by a graph, where the agents' properties are defined over the vertexes and the interagent interactions are defined over the bonds. The adaptability of the agents allows us to model the formation of opinions as an online learning process, where agents learn continuously as new information becomes available to the whole society (online learning). Through the application of statistical mechanics techniques we deduced a set of differential equations describing the dynamics of the system. We observed that by slowly varying the average peer influence in such a way that the agents attitude changes from conservative to liberal and back, the average social opinion develops a hysteresis cycle. Such hysteretic behavior disappears when the variance of the social influence distribution is large enough. In all the cases studied, the change from conservative to liberal behavior is characterized by the emergence of conservative clusters, i.e., a closed knitted set of society members that follow a leader who agrees with the social status quo when the rule B is challenged.

    This paper tests whether companies engage in opinion shopping and examines the role of audit committees when auditors are dismissed (1996-98). There are three findings. First, US companies strategically dismiss when incumbent auditors are more likely to issue unfavorable audit opinions compared to newly appointed auditors. I estimate opinion shopping motivates 17% of auditor dismissals, and I find opinion shopping dismissals occur significantly later in the reporting period than other dismiss...

    Full Text Available Abstract Background Sequence and transcriptional variability within and between individuals are typically studied independently. The joint analysis of sequence and gene expression variation (genetical genomics provides insight into the role of linked sequence variation in the regulation of gene expression. We investigated the role of sequence variation in cis on gene expression (cis sequence effects in a group of genes commonly studied in cancer research in lymphoblastoid cell lines. We estimated the proportion of genes exhibiting cis sequence effects and the proportion of gene expression variation explained by cis sequence effects using three different analytical approaches, and compared our results to the literature. Results We generated gene expression profiling data at N = 697 candidate genes from N = 30 lymphoblastoid cell lines for this study and used available candidate gene resequencing data at N = 552 candidate genes to identify N = 30 candidate genes with sufficient variance in both datasets for the investigation of cis sequence effects. We used two additive models and the haplotype phylogeny scanning approach of Templeton (Tree Scanning to evaluate association between individual SNPs, all SNPs at a gene, and diplotypes, with log-transformed gene expression. SNPs and diplotypes at eight candidate genes exhibited statistically significant (p cis sequence effects in our study, respectively. Conclusion Based on analysis of our results and the extant literature, one in four genes exhibits significant cis sequence effects, and for these genes, about 30% of gene expression variation is accounted for by cis sequence variation. Despite diverse experimental approaches, the presence or absence of significant cis sequence effects is largely supported by previously published studies.

  3. Public opinion factors regarding nuclear power

    International Nuclear Information System (INIS)

    This paper is an effort to identify, as comprehensively as possible, public concerns about nuclear power, and to assess, where possible, the relative importance of these concerns as they relate to government regulation of and policy towards nuclear power. It is based on some two dozen in-depth interviews with key communicators representing the nuclear power industry, the environmental community, and government, as well as on the parallel efforts in our research project: (1) review of federal court case law, (2) a selective examination of the Nuclear Regulatory Commission (NRC) administrative process, and (3) the preceding George Mason University research project in this series. The paper synthesizes our findings about public attitudes towards nuclear power as expressed through federal court case law, NRC administrative law, public opinion surveys, and direct personal interviews. In so doing, we describe the public opinion environment in which the nuclear regulatory process must operate. Our premise is that public opinion ultimately underlies the approaches government agencies take towards regulating nuclear power, and that, to the degree that the nuclear power industry's practices are aligned with public opinion, a more favorable regulatory climate is possible

  6. RAMI analysis of the ITER CIS

    International Nuclear Information System (INIS)

    Highlights: • We performed the functional analysis of the ITER CIS. • We performed a failure mode analysis of the ITER CIS. • We estimated the reliability and availability of the ITER CIS. • The ITER RAMI approach was applied to the ITER CIS for technical risk control in the design phase. - Abstract: ITER is the first worldwide international project aiming to design a device that proves the physics and technological basis for fusion power plants to produce nuclear fusion energy. In the project, the RAMI approach (reliability, availability, maintainability and inspectability) has been adopted for technical risk control to guide the design of components in preparation for operation and maintenance. RAMI analysis of the ITER central interlock system (CIS), which shall provide investment protection for the ITER systems was performed on the conceptual design. A functional breakdown was prepared in a bottom-up approach, resulting in the system being divided into 5 main functions and 7 sub-functions which are described using the IDEFØ method. Reliability block diagrams (RBDs) were prepared to estimate the reliability and availability of each function under stipulated operating conditions. Initial and expected scenarios were analyzed to define risk-mitigation actions. The inherent availability of the ITER CIS expected after implementation of mitigating actions was calculated to be 99.86% over 2 years, which is the typical interval of the scheduled maintenance cycles. A failure modes, effects and criticality analysis (FMECA) was performed to initiate risk mitigation action. Criticality matrices highlight the risks of the different failure modes with regard to the probability of their occurrence and impact on operations. It was assessed that the availability of the ITER CIS, with appropriate mitigating actions applied, meets the project availability requirement for the system

    2014-01-01

    We investigate the emergence of extreme opinion trends in society by employing statistical physics modeling and analysis on polls that inquire about a wide range of issues such as religion, economics, politics, abortion, extramarital sex, books, movies, and electoral vote. The surveys lay out a clear indicator of the rise of extreme views. The precursor is a nonlinear relation between the fraction of individuals holding a certain extreme view and the fraction of individuals that includes also moderates, e.g., in politics, those who are "very conservative" versus "moderate to very conservative" ones. We propose an activation model of opinion dynamics with interaction rules based on the existence of individual "stubbornness" that mimics empirical observations. According to our modeling, the onset of nonlinearity can be associated to an abrupt bootstrap-percolation transition with cascades of extreme views through society. Therefore, it represents an early-warning signal to forecast the transition from moderate ...

    2012-07-01

    -length studies of Swedish mass attitudes toward nuclear power appeared already in the late 1970-ies. Since then all SNES surveys have included measurements of Swedish opinions on various energy issues. A special election study was done in 1980 covering the nuclear power referendum. Beginning in 1986, SNES's election year measurements were supplemented by annual studies done by the newly founded SOM Institute at Univ. of Gothenburg. These annual measurements were from the start designed and coordinated by the research project Energy Opinion in Sweden, originally financially supported by the now non-existent National Board for Spent Fuel, but since 1999 financed by The Swedish Energy Agency. The analyses in the chapters in this English language book compendium have all been done and published under the auspices of the research project Energy Opinion in Sweden. The time span is quite long, over twenty years. The writing in Chapter 1 appeared already in 1991, while the results in Chapters 7 and 8 are from 2011.

  13. Public opinion on Fukushima Daiichi nuclear disaster

    International Nuclear Information System (INIS)

    This article showed trend of public opinion on nuclear power after Fukushima Daiichi nuclear disaster, for which the survey had been done five times under the same method and inquiries. Most unreliable source of information at disaster was government ministries and offices, whose unreliability sharply increased from 20% to about 50% after 3 months later and one year later after March 11 and reliability after 2 year and 5 months later (August 2013) was not high and almost comparable with unreliability of 27%. Nuclear disaster was most serious cause of Great East Japan earthquake disaster (60%) and not entirely ended due to such increase of contaminated water. Public opinion survey in August 2013 showed nuclear power stoppage totaled about 80% with immediate of about 30% and phaseout of about 50%, and possibility of occurrence of another nuclear accident comparable with Fukushima disaster was almost 80% with a belief not only earthquakes, tsunamis, terrorism but also human errors might initiate nuclear disaster if nuclear power restarted. Future most serious disaster would be earthquake (50%) and nuclear disaster (35%). Nuclear accident preparedness of government and local government was not enough (58% and 24%) and nothing (33% and 24%). Residents within UPZ (Urgent Protection action Planning Zone) of 30 km radius could not evacuate safely (57%) and entirely (22%). If government and local government encouraged damaged residents to come home with declaration of safety for evacuation area of nuclear accident, damaged residents might not return almost (46%) and entirely (9%). Notwithstanding people's strong feeling against nuclear power, LDP (Liberal Democratic Party) promoting nuclear power won an overwhelming victory at the election of House of Councilors in July 2013. Public opinion survey in August 2013 showed most important issue of voters was party's image (25%), economic measures (20%) and candidate's personality (13%), and nuclear power policy

    "What other people think" has always been an important piece of information during various decision-making processes. Today people frequently make their opinions available via the Internet, and as a result, the Web has become an excellent source for gathering consumer opinions. There are now numerous Web resources containing such opinions, e.g., product reviews forums, discussion groups, and Blogs. But, due to the large amount of information and the wide range of sources, it is essentially impossible for a customer to read all of the reviews and make an informed decision on whether to purchase the product. It is also difficult for the manufacturer or seller of a product to accurately monitor customer opinions. For this reason, mining customer reviews, or opinion mining, has become an important issue for research in Web information extraction. One of the important topics in this research area is the identification of opinion polarity. The opinion polarity of a review is usually expressed with values 'positive'...

  3. Opinion leadership and willingness to pay for residential photovoltaic systems

    International Nuclear Information System (INIS)

    According to diffusion theory, opinion leaders play an important role in the diffusion of new technologies through interpersonal communication with potential adopters. This study investigates the role and utility of opinion leadership in photovoltaic (PV) system diffusion. Specifically, the study proposes, examines, and considers the implications of the hypothesis that there is a positive relationship between willingness to pay (WTP) for a PV system and opinion leadership on PV-system adoption. The investigation employed an internet-based questionnaire to assess the use of interpersonal communication in decision-making on adoption, to identify opinion leaders on adoption, and to characterize their WTP. The response pool consisted of 488 individuals who lived in a detached house, owned a residential PV system, and were responsible for making the decision to adopt the system. The results support the hypothesis. Considering that subsidization preferentially incentivizes households with greater WTP to adopt PV systems, this suggests that subsidization is more effective than purchases of PV power under feed-in tariffs in promoting the diffusion of residential PV systems through interpersonal communication. -- Highlights: •Interpersonal communication about the adoption of PV systems is analyzed. •A questionnaire survey is conducted. •Opinion leaders on PV-system adoption are identified. •A relationship is confirmed between willingness to pay and opinion leadership. •Subsidization is more essential than feed-in tariffs from this point of view

    A review and analysis of 115 surveys of the general population between 1973 and 1978 (before the Three Mile Island accident, sudden gasoline price increases, and spot gasoline shortages) are presented. The survey data are organized and analyzed according to a set of categories described in Chapter 2. The public's definition of the energy situation is the focus of Chapter 3. Chapter 4 describes public opinion concerning energy conservation pertaining to transportation and domestic energy use -- whether it is efficacious, how knowledgeable people are about conservation, whether they favor it, and whether they engage in it. Findings on the solar energy alternative are described in Chapter 5. Public opinion concerning more conventional sources of energy -- oil and natural gas, coal, and nuclear energy -- are discussed in Chapter 6. In Chapter 7, a summary of analytical findings by 10 major sociodemographic characteristics is presented. Chapter 8 describes analytical findings using various social-psychological variables. A summary is presented in Chapter 9.

  5. Opinion Dynamics with Confirmation Bias

    CERN Document Server

    Allahverdyan, A E

    2014-01-01

    Background: Confirmation bias is the tendency to acquire or evaluate new information in a way that is consistent with one's preexisting beliefs. It is omnipresent in psychology, economics, and even scientific practices. Prior theoretical research of this phenomenon has mainly focused on its economic implications possibly missing its potential connections with broader notions of cognitive science. Methodology/Principal Findings: We formulate a (non-Bayesian) model for revising subjective probabilistic opinion of a confirmationally-biased agent in the light of a persuasive opinion. The revision rule ensures that the agent does not react to persuasion that is either far from his current opinion or coincides with it. We demonstrate that the model accounts for the basic phenomenology of the social judgment theory, and allows to study various phenomena such as cognitive dissonance and boomerang effect. The model also displays the order of presentation effect|when consecutively exposed to two opinions, the preferenc...

We find that the inclusion of balancers along with floaters and inflexibles brings about a critical point on parametric plane of the dynamical system, which results in the new kind of stable final states of the opinion dynamics, that seem to capture several intriguing features found often in mature democracies.

    细颗粒度观点挖掘需要解决观点句识别、要素抽取等关键问题。论文对国内外相关研究进行梳理,归纳现有观点句识别方法并找出影响识别率的原因,分析基于规则和基于统计的两类方法进行要素抽取的优势和不足。研究发现,机器学习方法或人工和机器相结合的方法是要素识别研究的基本趋势,观点本体和观点表达语言规律的研究需要进一步加强,应用领域有待扩展,观点抽取结果挖掘需进一步深入。%The key steps in fine-grained opinion mining are subjectivity classification and aspect extraction . By reviewing of domestic and foreign related research, the formulated definition of the opinion and aspect is made and the reasons of the low recognition rate are summarized. and then the advantages and disadvantages of two kinds of methods( based on rules and statistics ) are analyzed. It is found that the semi-supervised machine learning method is a research trend. This paper proposes to strengthen the research on linguistic rules and the ontology of opinion, to expand the application fields and make the comprehensive utilization of the results.

    Full Text Available In this paper we present a lexical approach that will identify opinion of web users popularly expressedusing short words or sms words. These words are pretty popular with diverse web users and are used forexpressing their opinion on the web. The study of opinion from web arises to know the diverse opinion ofweb users. The opinion expressed by web users may be on diverse topics such as politics, sports, products,movies etc. These opinions will be very useful to others such as, leaders of political parties, selectioncommittees of various sports, business analysts and other stake holders of products, directors andproducers of movies as well as to the other concerned web users. We use semantic based approach to findusers opinion from short words or sms words apart of regular opinionated phrases. Our approachefficiently detects opinion from opinionated texts using lexical analysis and is found to be better than theother approaches on different data sets.

    The aim of this study is to explore nurses' and patients' opinions about nurses in Poland going on strike. The study was carried out in Poland between January and June 2009, using 150 nurses and 150 hospitalized patients. The study was conducted using two questionnaire surveys. The main reasons why nursing strikes are organized, in the opinions of nurses, are: higher wages, the improvement of working conditions and the improvement of the image of the nursing profession. The main reasons why nursing strikes are organized, in the opinions of patients, are: higher wages, not abiding standards of employment by government and the improvement of the image of the nursing profession. The main reasons for a lack of active participation in strikes are holidays and occupational and economic matters. Patients and nurses support nursing strikes. Both nurses (53.3%) and patients (42%) said that organizing nursing strikes is right and might improve the occupational situation of nurses. PMID:24308205

    Since Puntam's seminal work on declining levels of social capital, the question of how social trust is formed has reached unprecedented heights of critical enquiry. While most of the current research concentrates on ethnic diversity and income inequality as the main influences driving down generalized trust, we focus on opinion polarization as another potential impact factor on trust. In more detail, we investigate the extent to which polarization over morally charged issues such as homsexuality, abortion and euthanasia affects individuals' likelihood to trust others. We hypothesize that moral issues have a natural tendency to divide societies' opinions into opposing poles and, thus, to challenge social cohesion in modern civil societies. Based on hierarchical analyses of the fifth wave of the World Values Survey (WVS) - comprising a sample of 39 countries - our results reveal that individuals living in countries characterized by more opinion polarization tend to have less trust in other people.

    A concise and simple synthetic approach to cis-syn-cis-triquinanes and -propellanes has been demonstrated via olefin metathesis starting with exo-nadic anhydride. This approach involves a ring-opening and ring-closing metathesis sequence of norbornene derivatives using Grubb's catalyst. Early-stage diallylation of norbornene derivatives is demonstrated followed by ring-closing metathesis that delivers propellanes exclusively. Surprisingly, ring-opening metathesis, late-stage diallylation, followed by ring-closing metathesis delivers triquinane as well as propellane derivatives. PMID:27050839

  17. Does the weather influence public opinion about climate change?

    2010-12-01

    Public opinion in North America about the science of anthropogenic climate change and the motivation for policy action has been variable over the past twenty years. The trends in public opinion over time have been attributed the general lack of pressing public concern about climate change to a range of political, economic and psychological factors. One driving force behind the variability in polling data from year to year may be the weather itself. The difference between what we “expect” - the climate - and what we “get” - the weather - can be a major source of confusion and obfuscation in the public discourse about climate change. For example, reaction to moderate global temperatures in 2007 and 2008 may have helped prompt the spread of a “global cooling” meme in the public and the news media. At the same time, a decrease in the belief in the science of climate change and the need for action has been noted in opinion polls. This study analyzes the relationship between public opinion about climate change and the weather in the U.S. since the mid-1980s using historical polling data from several major organizations (e.g. Gallup, Pew, Harris Interactive, ABC News), historical monthly air temperature (NCDC) and a survey of opinion articles from major U.S. newspapers (Washington Post, New York Times, Wall Street Journal, Houston Chronicle, USA Today). Seasonal and annual monthly temperature anomalies for the northeastern U.S and the continental U.S are compared with available national opinion data for three general categories of questions: i) Is the climate warming?, ii) Is the observed warming due to human activity?, and iii) Are you concerned about climate change? The variability in temperature and public opinion over time is also compared with the variability in the fraction of opinion articles in the newspapers (n ~ 7000) which express general agreement or disagreement with IPCC Summary for Policymakers consensus statements on climate change (“most of

    Full Text Available The essay analyzes the conflict which opened after the French Revolution between public opinion and ideology. In this space of reflection the second seemed sometimes as the hidden face of the first one. Public opinion historically represented the institutionalization of the possibility of a disagreement on the legitimacy of the body politic. It has thus made possible a speech on the political detached from religion. As is clear from the controversy of Napoleon against the ideologues and the Marxian critique, ideology does not get to be the science of social discourse and its alienation, to become a set of sophistry on social conditions. Discussing the arguments of Tocqueville, Bourdieu and Reynié about the deficit of reflexivity of public opinion, the author affirms its distance from the ideology, because it requires anyway an investment for religious believe his propositions.

    This report describes environmental testing of Siemen`s CIS modules. Charts and diagrams are presented on data concerning: temporary power loss of laminated mini-modules; the 50 thermal cycle test; the 10 humidity freeze cycle test; results after 1000 hours of exposure to damp heat; and interconnect test structures in damp heat testing. It is concluded that moisture ingress causes permanent increases in the series resistance of modules, and that improved packaging is needed for better high humidity reliability. Also, dry dark heat caused temporary power losses which were recovered in sunlight.

  20. Differing professional views or opinions: 1994 Special Review Panel

    International Nuclear Information System (INIS)

    In July 1994, the Executive Director for Operations of the US Nuclear Regulatory Commission (NRC) appointed a Special Review Panel to assess the Differing Professional View or Opinion (DPV/DPO) process, including its effectiveness, how well it is understood by employees, and the organizational climate for having such views aired and properly decided. An additional area within this review was to address the effectiveness of the DPO procedures as they pertain to public access and confidentiality. Further, the Panel was charged with the review of the submittals completed since the last review to identify employees who made significant contributions to the agency or to the public health and safety but had not been adequately recognized for this contribution. The report presents the Special Review Panel's evaluation of the NRC's current process for dealing with Differing Professional Views or Opinions. Provided in this report are the results of an employee opinion survey on the process; highlights and suggestions from interviews with individuals who had submitted a Differing Professional View or Opinion, as well as with agency managers directly involved with the Differing Professional Views or Opinions process; and the Special Review Panel's recommendations for improving the DPV/DPO process

    The activity of cis-cinnamic acid (cis-CA), one of the allelochemicals, in plants is very similar to that of indole-3-acetic acid (IAA), a natural auxin, and thus cis-CA has long been believed to be an analog of auxin. We have reported some structure-activity relationships studies by synthesizing over 250 cis-CA derivatives and estimating their inhibitory activities on root growth inhibition in lettuce. In this study, the compounds that showed low- or no-activity on root growth inhibition were recruited as candidates suppressors against cis-CA and/or auxin and tested for their activity. In the presence of cis-CA, lettuce root growth was inhibited; however, the addition of some cis-CA derivatives restored control-level root growth. Four compounds, (Z)-3-(4-isopropylphenyl)acrylic acid, (Z)-3-(3-butoxyphenyl)acrylic acid, (Z)-3-[3-(pentyloxy)phenyl]acrylic acid, and (Z)-3-(naphthalen-1-yl)acrylic acid were selected as candidates for a cis-CA selective suppressor they allowed the recovery of root growth from inhibition by cis-CA treatment without any effects on the IAA-induced effect or elongating activity by themselves. Three candidates significantly ameliorated the root shortening by the potent inhibitor derived from cis-CA. In brief, we have found some cis-CA selective suppressors which have never been reported from inactive cis-CA derivatives for root growth inhibition. cis-CA selective suppressors will play an important role in elucidating the mechanism of plant growth regulation.

    We investigate the emergence of extreme opinion trends in society by employing statistical physics modeling and analysis on polls that inquire about a wide range of issues such as religion, economics, politics, abortion, extramarital sex, books, movies, and electoral vote. The surveys lay out a clear indicator of the rise of extreme views. The precursor is a nonlinear relation between the fraction of individuals holding a certain extreme view and the fraction of individuals that includes also moderates, e.g., in politics, those who are “very conservative” versus “moderate to very conservative” ones. We propose an activation model of opinion dynamics with interaction rules based on the existence of individual “stubbornness” that mimics empirical observations. According to our modeling, the onset of nonlinearity can be associated to an abrupt bootstrap-percolation transition with cascades of extreme views through society. Therefore, it represents an early-warning signal to forecast the transition from moderate to extreme views. Moreover, by means of a phase diagram we can classify societies according to the percolative regime they belong to, in terms of critical fractions of extremists and people’s ties.

    Sentiment analysis and opinion mining is the field of study that analyzes people's opinions, sentiments, evaluations, attitudes, and emotions from written language. It is one of the most active research areas in natural language processing and is also widely studied in data mining, Web mining, and text mining. In fact, this research has spread outside of computer science to the management sciences and social sciences due to its importance to business and society as a whole. The growing importance of sentiment analysis coincides with the growth of social media such as reviews, forum discussions

    Sequence alignment of proteins and nucleic acids is a routine task in bioinformatics. Although the comparison of complete peptides, genes or genomes can be undertaken with a great variety of tools, the alignment of short DNA sequences and motifs entails pitfalls that have not been fully addressed yet. Here we confront the structural superposition of transcription factors with the sequence alignment of their recognized cis elements. Our goals are (i) to test TFcompare (http://floresta.eead.csic.es/tfcompare), a structural alignment method for protein-DNA complexes; (ii) to benchmark the pairwise alignment of regulatory elements; (iii) to define the confidence limits and the twilight zone of such alignments and (iv) to evaluate the relevance of these thresholds with elements obtained experimentally. We find that the structure of cis elements and protein-DNA interfaces is significantly more conserved than their sequence and measures how this correlates with alignment errors when only sequence information is considered. Our results confirm that DNA motifs in the form of matrices produce better alignments than individual sequences. Finally, we report that empirical and theoretically derived twilight thresholds are useful for estimating the natural plasticity of regulatory sequences, and hence for filtering out unreliable alignments.

  5. Democracy, public opinion, and nuclear weapons

    International Nuclear Information System (INIS)

    To the degree that people's fears of nuclear war are deep and pervasive, they become subject to manipulation by cynical or politically utopian promises, whether those promises be to abolish nuclear weapons from the earth or to create a leakproof peace shield (SDI). But the basic yearning for protection could also be mobilized to support serious arms reduction and arms control agreements. Nuclear weapons provide the basis for a vivid form of symbolic politics, perhaps equivalent in foreign policy considerations to the Korean and Vietnam wars during their durations, and in similar ways (although not necessarily as severe) as unemployment does among domestic policy issues. This paper presents survey research directed specifically at the role of public opinion on nuclear imagery (difference between expectation of nuclear war versus any kind of weapon war; willingness to spend on nuclear weapons versus conventional ones or general defense spending) can help in understanding these phenomena

    Full Text Available The number of messages that can be mined from online entries increases as the number of online application users increases. In Malaysia, online messages are written in mixed languages known as ‘Bahasa Rojak’. Therefore, mining opinion using natural language processing activities is difficult. This study introduces a Malay Mixed Text Normalization Approach (MyTNA and a feature selection technique based on Immune Network System (FS-INS in the opinion mining process using machine learning approach. The purpose of MyTNA is to normalize noisy texts in online messages. In addition, FS-INS will automatically select relevant features for the opinion mining process. Several experiments involving 1000 positive movies feedback and 1000 negative movies feedback have been conducted. The results show that accuracy values of opinion mining using Naïve Bayes (NB, k-Nearest Neighbor (kNN and Sequential Minimal Optimization (SMO increase after the introduction of MyTNA and FS-INS.

    2014-11-01

    Gene expression differences between divergent lineages caused by modification of cis regulatory elements are thought to be important in evolution. We assayed genome-wide cis and trans regulatory differences between maize and its wild progenitor, teosinte, using deep RNA sequencing in F1 hybrid and parent inbred lines for three tissue types (ear, leaf and stem). Pervasive regulatory variation was observed with approximately 70% of ∼17,000 genes showing evidence of regulatory divergence between maize and teosinte. However, many fewer genes (1,079 genes) show consistent cis differences with all sampled maize and teosinte lines. For ∼70% of these 1,079 genes, the cis differences are specific to a single tissue. The number of genes with cis regulatory differences is greatest for ear tissue, which underwent a drastic transformation in form during domestication. As expected from the domestication bottleneck, maize possesses less cis regulatory variation than teosinte with this deficit greatest for genes showing maize-teosinte cis regulatory divergence, suggesting selection on cis regulatory differences during domestication. Consistent with selection on cis regulatory elements, genes with cis effects correlated strongly with genes under positive selection during maize domestication and improvement, while genes with trans regulatory effects did not. We observed a directional bias such that genes with cis differences showed higher expression of the maize allele more often than the teosinte allele, suggesting domestication favored up-regulation of gene expression. Finally, this work documents the cis and trans regulatory changes between maize and teosinte in over 17,000 genes for three tissues.

  11. Impotent science, omnipotent public opinion

    International Nuclear Information System (INIS)

    Full text: Nowadays public opinion has become prominent when political leaders have themselves to vote. Even scientific or economical decisions are often taken more in accordance to these trends than to rational reasons. For a long time it has been widely accepted that a clear and pedagogical explanation was enough to make scientific issues understandable. For nearly 20 years, a true scientific and professional communication has been developed in France towards the general public to make nuclear industry acceptable. Nevertheless today, we notice that the acceptance of the nuclear option has lost many points in public polls. An accident, in the nuclear fields or in another fields, in one point or another of the planet can ruin the work of many years in communication. 1) In order to draw a more precise picture of public opinion, to follow these trends and make them more understandable, the CEA communication direction has built a 'public opinion barometer' dealing with the following fields: - Information on nuclear fields; - The nuclear actors; - The future of nuclear option; - Radioactive waste; - Risks perception; - Nuclear energy and other sources of energy; - Economy and nuclear power; - Image of nuclear. 2) Come and visit our labs to make up your own opinion: As communication methods through the classical media has, up to now, failed in changing public opinion regarding nuclear, the decision was made to offer to people the opportunity to meet searchers at work.400 'Communicating researchers' to day are volunteers to receive the public .They are trained to be able to explain their work to non specialists; they receive documents dealing with current events to help them answer to questions and they are invited to an annual general meeting (last one in January 2001). 85 laboratories are opened (civil and military ones). In 2000, nearly 10,000 visitors have come to us. In 2001, new additional operations will be lead toward young people, teachers, associations. (author)

    The Nowak modification of the Sznajd opinion dynamics model on the square lattice assumes that with probability β the opinions flip due to mass-media advertising from down to up, and vice versa. Besides, with probability α the Sznajd rule applies that a neighbour pair agreeing in its two opinions convinces all its six neighbours of that opinion. Our Monte Carlo simulations and mean-field theory find sharp phase transitions in the parameter space.

  15. Opinion evolution influenced by informed agents

    Fan, Kangqi; Pedrycz, Witold

    2016-11-01

    Guiding public opinions toward a pre-set target by informed agents can be a strategy adopted in some practical applications. The informed agents are common agents who are employed or chosen to spread the pre-set opinion. In this work, we propose a social judgment based opinion (SJBO) dynamics model to explore the opinion evolution under the influence of informed agents. The SJBO model distinguishes between inner opinions and observable choices, and incorporates both the compromise between similar opinions and the repulsion between dissimilar opinions. Three choices (support, opposition, and remaining undecided) are considered in the SJBO model. Using the SJBO model, both the inner opinions and the observable choices can be tracked during the opinion evolution process. The simulation results indicate that if the exchanges of inner opinions among agents are not available, the effect of informed agents is mainly dependent on the characteristics of regular agents, including the assimilation threshold, decay threshold, and initial opinions. Increasing the assimilation threshold and decay threshold can improve the guiding effectiveness of informed agents. Moreover, if the initial opinions of regular agents are close to null, the full and unanimous consensus at the pre-set opinion can be realized, indicating that, to maximize the influence of informed agents, the guidance should be started when regular agents have little knowledge about a subject under consideration. If the regular agents have had clear opinions, the full and unanimous consensus at the pre-set opinion cannot be achieved. However, the introduction of informed agents can make the majority of agents choose the pre-set opinion.

    Full Text Available Opinions are very much essential for any organization's development and success. It affects the quality of various products in a great way and will indicate how much the customer has satisfied with the product along with its strength and weakness. There are a number of ways of collecting opinions; it may be through a feedback register, or through forums and other online feedback survey facilities. The opinions are monitored and are used for improving the productivity of the product on which the opinion is received. After collecting opinions, it is important to analyze them. So we need a proper automated tool that can actually read through the comments and classify them according to the needs. The tool should be capable of going through a large set of comments in a short time and should be efficient enough to recognize almost any sentence we can throw at it.

    In this study, the Mo-electrode thin films were deposited by a two-stepped process, and the high-purity copper indium selenide-based powder (CuInSe2, CIS) was fabricated by hydrothermal process by Nanowin Technology Co. Ltd. From the X-ray pattern of the CIS precursor, the mainly crystalline phase was CIS, and the almost undetectable CuSe phase was observed. Because the CIS powder was aggregated into micro-scale particles and the average particle sizes were approximately 3 to 8 μm, the CIS power was ground into nano-scale particles, then the 6 wt.% CIS particles were dispersed into isopropyl alcohol to get the solution for spray coating method. Then, 0.1 ml CIS solution was sprayed on the 20 mm × 10 mm Mo/glass substrates, and the heat treatment for the nano-scale CIS solution under various parameters was carried out in a selenization furnace. The annealing temperature was set at 550°C, and the annealing time was changed from 5 to 30 min, without extra Se content was added in the furnace. The influences of annealing time on the densification, crystallization, resistivity (ρ), hall mobility (μ), and carrier concentration of the CIS absorber layers were well investigated in this study.

  1. Should I Care about Your Opinion? Detection of Opinion Interestingness and Dynamics in Social Media

    Directory of Open Access Journals (Sweden)

    Diana Maynard

    2014-08-01

    Full Text Available In this paper, we describe a set of reusable text processing components for extracting opinionated information from social media, rating it for interestingness, and for detecting opinion events. We have developed applications in GATE to extract named entities, terms and events and to detect opinions about them, which are then used as the starting point for opinion event detection. The opinions are then aggregated over larger sections of text, to give some overall sentiment about topics and documents, and also some degree of information about interestingness based on opinion diversity. We go beyond traditional opinion mining techniques in a number of ways: by focusing on specific opinion-target extraction related to key terms and events, by examining and dealing with a number of specific linguistic phenomena, by analysing and visualising opinion dynamics over time, and by aggregating the opinions in different ways for a more flexible view of the information contained in the documents.

  10. Automated assembly of oligosaccharides containing multiple cis-glycosidic linkages

    Science.gov (United States)

    Hahm, Heung Sik; Hurevich, Mattan; Seeberger, Peter H.

    2016-09-01

    Automated glycan assembly (AGA) has advanced from a concept to a commercial technology that rapidly provides access to diverse oligosaccharide chains as long as 30-mers. To date, AGA was mainly employed to incorporate trans-glycosidic linkages, where C2 participating protecting groups ensure stereoselective couplings. Stereocontrol during the installation of cis-glycosidic linkages cannot rely on C2-participation and anomeric mixtures are typically formed. Here, we demonstrate that oligosaccharides containing multiple cis-glycosidic linkages can be prepared efficiently by AGA using monosaccharide building blocks equipped with remote participating protecting groups. The concept is illustrated by the automated syntheses of biologically relevant oligosaccharides bearing various cis-galactosidic and cis-glucosidic linkages. This work provides further proof that AGA facilitates the synthesis of complex oligosaccharides with multiple cis-linkages and other biologically important oligosaccharides.

    Full Text Available Aim: when programming a medical test such as capsule endoscopy (CE, finding the closest point between the patient's experience and his/her expectation is essential to improve any further explorations. For this purpose we designed a form which tries to collect the information required. Material and methods: from December 2003 to January 2005 we examined the small intestine of 98 patients with the help of CE. Later they were sent an anonymous questionnaire in July 2005, which included 10 questions upon the origin and previous knowledge of the patient about this technique, their tolerance to it, and the value they attached to it with regard to finding a new diagnosis and assigning different treatments, and also the incidence in the positive or negative evolution of their disease in particular and of medicine in general. Results: answer rate reached 58% and was slightly higher among women and people over 70 years; 80% of repliers had been informed about CE by a physician, while nearly all the rest had received previous information from the media; 37% had had symptoms for more than 12 months, while only 17% had suffered them for one month before the exploration. A bit over 30% did not know what the specific diagnostic field of the test was (most of them women and young people, although most of them were not surprised by the procedure. Over 75% showed "acceptable" or "excellent" tolerance, while 5.5% (most of them young people found it hard to bear. The opinion about its utility in the diagnosis was 37%, and although 70% thought that CE had revealed nothing new about their pathology, over 60% declared feeling better after the test; 84% pointed out that it had achieved a breakthrough for their quality of life (most of them men and very old people, and only 13% thought it was worthless. However, nearly all the answers agreed in that CE was an "important" or "very important" diagnostic device. Conclusions: after the test using CE, the diagnostic benefit

    Arlt, Dorothee; Wolling, Jens

    2016-10-01

    Based on a literature review on factors that explain media effects and previous findings on media coverage and public opinion on nuclear power, this article examines the effects of Fukushima on media coverage and public opinion in Germany in two studies. The first study uses content analysis data to analyse changes in media coverage, and the second one is based on panel survey data to examine attitude changes on an individual level. The results of both studies show changes in media coverage and public opinion on nuclear power. Furthermore, the second study reveals that individual attitude changes cannot necessarily be explained by the same factors as the distribution of attitudes.

    2016-06-01

    Full Text Available By employing the theoretical framework of framing, the present paper attempts to examine the Icelandic media’s coverage of the 2013 parliamentary election by paying particular attention to coverage of public opinion polls and the policies of the political parties, i.e. the “horse-race” frame and the issue frame, and to examine media’s reliance on experts for interpretation of election news. Seven online news media, two newspapers, two radio stations and two television channels were monitored for 25 days prior to Election Day, i.e. from April 2 to April 26, 2013, - resulting in 1377 election news stories. The findings show, for example, that 29.8% of all the election news stories had public opinion polls as their primary angle while 12% of the stories were primarily issue-oriented. In addition, the media rely on experts for interpretation of the polls; five of the 10 most interviewed or quoted sources on public opinion surveys were political science experts who were affiliated with universities. Finally, news coverage of polls was generally amplified as media outlets had a tendency to report on public opinion polls that were commissioned by other media.

  14. Public opinion and nuclear power decision-making

    International Nuclear Information System (INIS)

    This document discusses public opinion regarding nuclear power which is particularly difficult to tie down because of five important paradoxes that characterize it: it can be based on sound reason, but also on intense emotion; it is both national and local in perspective; at varying times it has seen nuclear power as both ''clean'' and ''dirty''; it believes nuclear power is both economic, and uneconomic; and nuclear power is perceived as having a fairly safe record, but being potentially unsafe. Equally as complex as the process by which public opinion is formed is the process by which it is converted into public policy. The American political system has numerous checks and balances designed to moderate the power of public opinion. A complex series of legislative, judicial, and executive branch hurdles must be cleared before any idea, however popular, can become day-to-day operating reality in government. As a result, major changes in policy or programs are difficult, and we may expect that nuclear power will be no different; radical change in one direction or the other is unlikely. Nevertheless, carefully focused programs could achieve modest progress, and carefully designed public opinion surveys could support such programs

    Credit Cards Not Candy Nowadays, colleges and universities have become a big market for many banks and competition is fierce. At the start of every new semester, numerous banks will send their staff to promote credit cards among college students and some students even havetwo or three credit cards.As long as they are able to pay off theiroverdraft, it’s acceptable to give college stu-dents credit cards. However, students don’have stable incomes. By targeting this group banks have to lower the threshold for cardapplications. Sometimes, they even do nocheck student applicants’ repayment capa-bilities. An important reason for this practiceis that banks know behind the students aretheir parents. If students can’t pay back thecredit, banks will turn to the parents to make good the outstanding amounts.

  1. EU-CIS joint study project 2

    International Nuclear Information System (INIS)

    Long-term protective measures taken in the CIS following the Chernobyl accident included relocating people from the most contaminated areas as well as continuing the restrictions on using foodstuffs contaminated with 137Cs. The levels at which these countermeasures were introduced or still are being introduced for dose-saving purposes have been used to estimate avertable doses based on population distributions on both dose rate and surface contamination density of 137Cs in space and time. The averted and avertable doses have been quantified by parameters of these distributions and intervention levels for relocation and foodstuff restrictions. The countermeasure efficiencies in agricultural production and various protection strategies in the agrosphere in Russia have been investigated. In addition, methods for estimating avertable radiation risks as well as residual risk from continuing exposures in terms of age-dependent radiation risk factors have been suggested. The sensitivity of changing intervention levels expressed in terms of changes in costs and avertable collective doses have been explored. The application of the present methodology in the decision-making process following a nuclear accident is discussed. Suggestions are made for including the methodology in simple models to be used for aiding decision-making on introducing protective measures. (au) (12 tabs., 8 ills., 22 refs.)

  2. Opinion dynamics: inhomogeneous Boltzmann-type equations modelling opinion leadership and political segregation

    CERN Document Server

    Düring, Bertram

    2015-01-01

    We propose and investigate different kinetic models for opinion formation, when the opinion formation process depends on an additional independent variable, e.g. a leadership or a spatial variable. More specifically, we consider:(i) opinion dynamics under the effect of opinion leadership, where each individual is characterised not only by its opinion, but also by another independent variable which quantifies leadership qualities; (ii) opinion dynamics modelling political segregation in the `The Big Sort', a phenomenon that US citizens increasingly prefer to live in neighbourhoods with politically like-minded individuals. Based on microscopic opinion consensus dynamics such models lead to inhomogeneous Boltzmann-type equations for the opinion distribution. We derive macroscopic Fokker-Planck-type equations in a quasi-invariant opinion limit and present results of numerical experiments.

  5. International public opinion: a project to provide an overview and comparisons between countries

    International Nuclear Information System (INIS)

    Full text: During 1995, Laurent Leger, a Visiting Research Officer seconded to the Uranium Institute by Cogema, undertook a comparison of public opinion polls from different countries in an attempt to obtain an overview of public opinion towards nuclear energy on an international scale. He found that such a comparison was very difficult due to subtle differences in questions that appeared similar. In his report on his work he concluded: 'It has been found that it is hard to compare opinion polls that have not been designed for this purpose. ... It is clear that better comparisons of public opinion internationally could be made, but it may well be that in order to do so it will be necessary to collect data specifically for this purpose.' The Institute's Committee on Nuclear Energy and the Public, after receiving the report and discussing its contents, concluded that it would be useful to endeavour to obtain an international overview of public opinion regarding the nuclear option and to facilitate comparisons between different countries. Three methods of achieving this were considered: an international public opinion survey could be undertaken, those wishing to obtain comparisons could ask questions in their country that had already been asked elsewhere, or a set of standard questions could be developed to be used in public opinion surveys. The last of these options was selected and a working group was formed to develop a series of questions. These have now been included in public opinion polls in three countries: the UK, France and Canada. Some results of the comparison of the responses from these surveys will be available for presentation at PIME '98. Organisations in several countries have committed to participating in this project, and a number of others are considering doing so. Full results and access to the data for more detailed study, are only available to those who participate. (author)

    2006-12-01

    Abortion laws in Latin America and the Caribbean (LAC) are highly restrictive and may not reflect public opinion on the issue. This article synthesizes the survey literature on attitudes toward abortion in the region. We searched standard computer indexing services and polled colleagues at regional meetings to identify every methodologically sound quantitative study of abortion opinion in LAC published between 1985 and 2005. Of the 26 studies that met inclusion criteria, none was conducted in the Caribbean, 11 were conducted in Brazil, 11 in Mexico, 3 in Argentina, and 1 in Colombia. The majority of populations surveyed support abortion under a greater number of circumstances than are permitted in their respective countries, particularly in cases of rape and threat to life or health. Future abortion opinion surveys should ask about support for the legality of abortion rather than about abstract acceptance of abortion, and questions should be worded carefully to capture the complexities of the public's views on this issue.

    The social policy of the Thatcher government is characterized by an abrupt shift in the direction of the private sector. To what extent does this reflect what people want? The Institute of Economic Affairs conclude from the only suitable national opinion survey that such a move is strongly supported. Our reanalysis of their data shows that this strand in public opinion can coexist with, and need not contradict, an equal public enthusiasm for state welfare. Such results have important implications for our understanding of social policy. We conclude, therefore, with a discussion of contrasting marxist and liberal accounts which seeks to show that the evidence of ambivalence in popular attitudes about the welfare state supports particular developments in theory.

    2012-01-01

    Opinion dynamics concerns social processes through which populations or groups of individuals agree or disagree on specific issues. As such, modelling opinion dynamics represents an important research area that has been progressively acquiring relevance in many different domains. Existing approaches have mostly represented opinions through discrete binary or continuous variables by exploring a whole panoply of cases: e.g. independence, noise, external effects, multiple issues. In most of these cases the crucial ingredient is an attractive dynamics through which similar or similar enough agents get closer. Only rarely the possibility of explicit disagreement has been taken into account (i.e., the possibility for a repulsive interaction among individuals' opinions), and mostly for discrete or 1-dimensional opinions, through the introduction of additional model parameters. Here we introduce a new model of opinion formation, which focuses on the interplay between the possibility of explicit disagreement, modulate...

  9. EUROPEANS AND RADIOACTIVE WASTE - OPINIONS, BELIEFS AND CONCERNS

    Energy Technology Data Exchange (ETDEWEB)

    Webster, S.; Taylor, D.M.

    2003-02-27

    In the autumn of 1998, the European Commission conducted a public opinion survey on radioactive waste. Roughly 16,000 people across the European Union (EU) were questioned in face to face interviews. A similar survey was carried out three years later in October and November of 2001, though this time questions of a broader nature concerning nuclear issues in general were also introduced. A comparison of the results of the two surveys shows that in the intervening period there have been very few significant changes in opinion. In particular, the events of 11 September 2001 appear to have had no measurable impact on people's views. The results of the surveys have been analyzed and the key findings extracted and, where possible, interpreted. Though some of these findings might perhaps have been expected, others are somewhat surprising or even worrying, especially for the nuclear sector. However, people still seem prepared to accept that nuclear power should remain an option for electricity production in the EU, but the policy makers and the nuclear industry must demonstrate that the waste issue can be managed both safely and with respect for future generations.

  10. French opinion on Nuclear Energy

    International Nuclear Information System (INIS)

    Contrary to what many think or say, most French people do not have a clear-cut opinion about nuclear power. And until public opinion can be accurately assessed, we should be worried of speaking on its behalf. More than half the population of France believes that nuclear power is the cheapest option, but 40% of them have no idea what the situation really is. The French are keenly aware of the what is at stake at the international level, and the fact that energy is becoming a worldwide issue. What they are most concerned about is nuclear waste and the possibility of a catastrophe of the Chernobyl type occurring. Disquiet about the first is now dissipating, after having increased. But attitudes about the second are ambivalent. A quarter of the French are very ignorant about radioactivity. 20% of the population complain that not enough information is forthcoming, particularly as concerns advances in technology. As can be anticipated, awareness of the question of climate change is growing year by year, with increased reporting of storms, floods and heat waves

    Full Text Available The title compound (systematic name: cis-anti-cis-2,5,8,15,18,21-hexaoxatricyclo[20.4.0.09,14]hexacosane acetonitrile disolvate, C20H36O6·2CH3CN, crystallizes from an acetonitrile solution of dicyclohexane-18-crown-6 on evaporation. The molecule is arranged around a center of symmetry with half the crown ether molecule and one molecule of acetonitrile symmetry independent. All O—C—C—O torsion angles are gauche while all C—O—C—C angles are trans. The sequence of torsion angles is [(tg+t(tg−t]3; the geometry of oxygen atoms is close to pseudo-D3d with three atoms below and three atoms above the mean plane, with an average deviation of ±0.16 (1 Å from the mean plane. This geometry is identical to that observed in metal ion complexes of dicyclohexane-18-crown-6 but differs significantly from the conformation of a free unsolvated molecule. Each acetonitrile molecule connects to a crown ether molecule via two of its methyl group H atoms (C—H...O. Weaker interactions exist between the third H atom of the acetonitrile methyl group and an O atom of a neighbouring crown ether molecule (C—H...O; and between the N atom of the acetonitrile molecule and a H atom of another neighbouring crown ether molecule. All these intermolecular interactions create a three-dimensional network stabilizing the disolvate.

  14. Consensus Formation on Simplicial Complex of Opinions

    2012-01-01

    Geometric realization of opinion is considered as a simplex and the opinion space of a group of individuals is a simplicial complex whose topological features are monitored in the process of opinion formation. The agents are physically located on the nodes of the scale-free network. Social interactions include all concepts of social dynamics present in the mainstream models augmented by four additional interaction mechanisms which depend on the local properties of opinions and their overlapping properties. The results pertaining to the formation of consensus are of particular interest. An analogy with quantum mechanical pure states is established through the application of the high dimensional combinatorial Laplacian.

The energy barrier to internal conversion from trans to cis is much higher than the thermal energy available in molecular clouds. Thus, only the most stable conformer (trans) is expected to exist in detectable amounts. We report the first interstellar detection of cis-HCOOH. Its presence in ultraviolet (UV) irradiated gas exclusively (the Orion Bar photodissociation region), with a low trans-to-cis abundance ratio of 2.8+-1.0, supports a photoswitching mechanism: a given conformer absorbs a stellar photon that radiatively excites the molecule to electronic states above the interconversion barrier. Subsequent fluorescent decay leaves the molecule in a different conformer form. This mechanism, which we specifically study with ab initio quantum calculations, was not considered in Space before but likely induces structural changes of a variety of interstellar molecules submitted to UV radiation.

    2016-01-01

    Bioinformatics tools can be employed to identify conserved cis-sequences in sets of coregulated plant genes because more and more gene expression and genomic sequence data become available. Knowledge on the specific cis-sequences, their enrichment and arrangement within promoters, facilitates the design of functional synthetic plant promoters that are responsive to specific stresses. The present chapter illustrates an example for the bioinformatic identification of conserved Arabidopsis thaliana cis-sequences enriched in drought stress-responsive genes. This workflow can be applied for the identification of cis-sequences in any sets of coregulated genes. The workflow includes detailed protocols to determine sets of coregulated genes, to extract the corresponding promoter sequences, and how to install and run a software package to identify overrepresented motifs. Further bioinformatic analyses that can be performed with the results are discussed. PMID:27557771

    SOCS proteins play a major role in the regulation of cytokine signaling. They are recruited to activated receptors and can suppress signaling by different mechanisms including targeting of the receptor complex for proteasomal degradation. The activity of SOCS proteins is regulated at different levels including transcriptional control and posttranslational modification. We describe here a novel regulatory mechanism for CIS, one of the members of this protein family. A CIS mutant deficient in recruitment of the Elongin B/C complex completely failed to suppress STAT5 activation. This deficiency was not caused by altered turnover of CIS but by loss of cytokine receptor interaction. Intriguingly, no such effect was seen for binding to MyD88. The interaction between CIS and the Elongin B/C complex, which depends on the levels of uncomplexed Elongin B/C, was easily disrupted. This regulatory mechanism may be unique for CIS, as similar mutations in SOCS1, -2, -3, -6, and -7 had no functional impact. Our findings indicate that the SOCS box not only plays a role in the formation of E3 ligase complexes but, at least for CIS, can also regulate the binding modus of SOCS box-containing proteins.

    Full Text Available Opinion Mining is related to detect the opinion of the author expressed in the document. The primary task in the field of opinion Mining is Subjectivity Analysis which finds whether the document is subjective or objective. Subjectivity shows that the document contains some opinionated part, while the objectivity shows thatthe document is far behind from the opinionated part i.e. it has no sentiments containing. The next task is Sentiment Polarity Analysis which differentiates the documents according to positivity and negativity. But presently there is no automated system which can perform this task. We are developing a system which can findthe degree of polarity of each document and according to it assign a human like rating to that document. At last it generates the summary of review which contains only the highly subjective and feature related part of the document.

  11. Opinions from the front lines of cat colony management conflict.

    M Nils Peterson

    Full Text Available Outdoor cats represent a global threat to terrestrial vertebrate conservation, but management has been rife with conflict due to differences in views of the problem and appropriate responses to it. To evaluate these differences we conducted a survey of opinions about outdoor cats and their management with two contrasting stakeholder groups, cat colony caretakers (CCCs and bird conservation professionals (BCPs across the United States. Group opinions were polarized, for both normative statements (CCCs supported treating feral cats as protected wildlife and using trap neuter and release [TNR] and BCPs supported treating feral cats as pests and using euthanasia and empirical statements. Opinions also were related to gender, age, and education, with females and older respondents being less likely than their counterparts to support treating feral cats as pests, and females being less likely than males to support euthanasia. Most CCCs held false beliefs about the impacts of feral cats on wildlife and the impacts of TNR (e.g., 9% believed feral cats harmed bird populations, 70% believed TNR eliminates cat colonies, and 18% disagreed with the statement that feral cats filled the role of native predators. Only 6% of CCCs believed feral cats carried diseases. To the extent the beliefs held by CCCs are rooted in lack of knowledge and mistrust, rather than denial of directly observable phenomenon, the conservation community can manage these conflicts more productively by bringing CCCs into the process of defining data collection methods, defining study/management locations, and identifying common goals related to caring for animals.

    It is important for many different applications such as government and business intelligence to analyze and explore the diffusion of public opinions on social media. However, the rapid propagation and great diversity of public opinions on social media pose great challenges to effective analysis of opinion diffusion. In this paper, we introduce a visual analysis system called OpinionFlow to empower analysts to detect opinion propagation patterns and glean insights. Inspired by the information diffusion model and the theory of selective exposure, we develop an opinion diffusion model to approximate opinion propagation among Twitter users. Accordingly, we design an opinion flow visualization that combines a Sankey graph with a tailored density map in one view to visually convey diffusion of opinions among many users. A stacked tree is used to allow analysts to select topics of interest at different levels. The stacked tree is synchronized with the opinion flow visualization to help users examine and compare diffusion patterns across topics. Experiments and case studies on Twitter data demonstrate the effectiveness and usability of OpinionFlow. PMID:26356890

  14. CisMiner: genome-wide in-silico cis-regulatory module prediction by fuzzy itemset mining.

    Directory of Open Access Journals (Sweden)

    Carmen Navarro

    Full Text Available Eukaryotic gene control regions are known to be spread throughout non-coding DNA sequences which may appear distant from the gene promoter. Transcription factors are proteins that coordinately bind to these regions at transcription factor binding sites to regulate gene expression. Several tools allow to detect significant co-occurrences of closely located binding sites (cis-regulatory modules, CRMs. However, these tools present at least one of the following limitations: 1 scope limited to promoter or conserved regions of the genome; 2 do not allow to identify combinations involving more than two motifs; 3 require prior information about target motifs. In this work we present CisMiner, a novel methodology to detect putative CRMs by means of a fuzzy itemset mining approach able to operate at genome-wide scale. CisMiner allows to perform a blind search of CRMs without any prior information about target CRMs nor limitation in the number of motifs. CisMiner tackles the combinatorial complexity of genome-wide cis-regulatory module extraction using a natural representation of motif combinations as itemsets and applying the Top-Down Fuzzy Frequent- Pattern Tree algorithm to identify significant itemsets. Fuzzy technology allows CisMiner to better handle the imprecision and noise inherent to regulatory processes. Results obtained for a set of well-known binding sites in the S. cerevisiae genome show that our method yields highly reliable predictions. Furthermore, CisMiner was also applied to putative in-silico predicted transcription factor binding sites to identify significant combinations in S. cerevisiae and D. melanogaster, proving that our approach can be further applied genome-wide to more complex genomes. CisMiner is freely accesible at: http://genome2.ugr.es/cisminer. CisMiner can be queried for the results presented in this work and can also perform a customized cis-regulatory module prediction on a query set of transcription factor binding

    Most recent advances in metallation chemistry have centred on the bulky secondary amide 2,2,6,6-tetramethylpiperidide (TMP) within mixed metal, often ate, compositions. However, the precursor amine TMP(H) is rather expensive so a cheaper substitute would be welcome. Thus this study was aimed towards developing cheaper non-TMP based mixed-metal bases and, as cis-2,6-dimethylpiperidide (cis-DMP) was chosen as the alternative amide, developing cis-DMP zincate chemistry which has received meagre attention compared to that of its methyl-rich counterpart TMP. A new lithium diethylzincate, [(TMEDA)LiZn(cis-DMP)Et2] (TMEDA=N,N,N',N'-tetramethylethylenediamine) has been synthesised by co-complexation of Li(cis-DMP), Et2Zn and TMEDA, and characterised by NMR (including DOSY) spectroscopy and X-ray crystallography, which revealed a dinuclear contact ion pair arrangement. By using N,N-diisopropylbenzamide as a test aromatic substrate, the deprotonative reactivity of [(TMEDA)LiZn(cis-DMP)Et2] has been probed and contrasted with that of the known but previously uninvestigated di-tert-butylzincate, [(TMEDA)LiZn(cis-DMP)tBu2]. The former was found to be the superior base (for example, producing the ortho-deuteriated product in respective yields of 78% and 48% following D2O quenching of zincated benzamide intermediates). An 88% yield of 2-iodo-N,N-diisopropylbenzamide was obtained on reaction of two equivalents of the diethylzincate with the benzamide followed by iodination. Comparisons are also drawn using 1,1,1,3,3,3-hexamethyldisilazide (HMDS), diisopropylamide and TMP as the amide component in the lithium amide, Et2Zn and TMEDA system. Under certain conditions, the cis-DMP base system was found to give improved results in comparison to HMDS and diisopropylamide (DA), and comparable results to a TMP system. Two novel complexes isolated from reactions of the di-tert-butylzincate and crystallographically characterised, namely the pre-metallation complex [{(iPr)2N(Ph)C=O}LiZn(cis

  16. Measuring and Understanding Public Opinion on Human Evolution

    Science.gov (United States)

    Gwon, Misook

    The theory of evolution has long generated controversy in American society, but Americans' attitudes about human evolution are often neglected in studies of "culture wars" and the nature of mass belief systems more generally (Berkman and Plutzer 2010; Freeland and Houston 2009). Gallup and other survey organizations have polled about evolution, but offered limited response categories that mask complexity in public opinion (Bishop 2006; Moore 2008). The main problems concerning the leading survey questions about evolution are: first, questions measure only a single dimension, thus they ignore the potential for multidimensionality in people's attitudes. Second, depending on question wording and response options, the results of public opinion surveys vary by polling groups. This is an example of measurement error which misleads the interpretation and impression of American public opinion on the origin of humankind. A number of studies have analyzed Americans' beliefs about evolution and hypothesized about the influential effects of several factors (Deckman 2002; Mazur 2005; Mooney 2005; Miller et al. 2006; Newport 2006; Forrest 2007;Nisbet and Goidel 2007;Scott 2009). However, there remains a lack of complete understanding of what Americans know and believe about human evolution. Given the salience of this issue and the significant influence of public opinion on policy-making in America (Page and Shapiro 1992; Stimson 2004; Newport 2004), the measurement error and explanation of polling results on controversial issues related to this topic are in need of clarification. In this study, I address these deficiencies with analyses of data from a 2008 national survey by Harris Interactive (n= 4,626) that included numerous measures of factual knowledge and beliefs about evolution. The items offer more nuanced response options than the standard three-category question asked for decades by the Gallup poll. The Harris survey also had multiple measures of religiosity and the

    1983-01-01

    The Corporate Information System (CIS), an integrated information system intended to tie the corporation together as a functioning entity, is described. In addition to being a major upgraded automated data processing system, the CIS is a management philosophy which recognizes data as a valuable corporate resource and which distinguishes between data and selected data, or information. It further recognizes that different users need different kinds of information. Plans for CIS development are discussed. It will offer its users not just after-the-fact data, but timely information in a format that is meaningful and useful to the particular user, so that the information can be applied in planning, controlling, and decision making by all levels of management. In effect, CIS will help the corporation itself to function as a total, integrated system by typing together administrative activities through information exchange. The CIS supports the operational, tactical control, and strategic planning functions of the corporation. Operational functions are the day-to-day processing necessary to support the corporation's work, such as purchasing and payroll.

    Dynamic social opinion models have been widely studied on undirected networks, and most of them are based on spin interaction models that produce a consensus. In reality, however, many networks such as Twitter and the World Wide Web are directed and are composed of both unidirectional and bidirectional links. Moreover, from choosing a coffee brand to deciding who to vote for in an election, two or more competing opinions often coexist. In response to this ubiquity of directed networks and the coexistence of two or more opinions in decision-making situations, we study a nonconsensus opinion model introduced by Shao et al. [Phys. Rev. Lett. 103, 018701 (2009)PRLTAO0031-900710.1103/PhysRevLett.103.018701] on directed networks. We define directionality ξ as the percentage of unidirectional links in a network, and we use the linear correlation coefficient ρ between the in-degree and out-degree of a node to quantify the relation between the in-degree and out-degree. We introduce two degree-preserving rewiring approaches which allow us to construct directed networks that can have a broad range of possible combinations of directionality ξ and linear correlation coefficient ρ and to study how ξ and ρ impact opinion competitions. We find that, as the directionality ξ or the in-degree and out-degree correlation ρ increases, the majority opinion becomes more dominant and the minority opinion's ability to survive is lowered.

    While the study of nationalism has received much attention throughout the social sciences and humanities, the experimental investigation of it lags behind. In this paper we review recent advances in the examination of implicit nationalism. In the first set of experiments we survey, the Palestinian, Israeli, Italian, and Russian flags were primed (or not, in the control conditions) and their effects on political thought and behavior were tested. In the second set the American or the Israeli flag was primed (or not) and prejudice toward African-Americans or Palestinians (respectively) was examined. The results of all experiments suggest that the implicit activation of national cues has far-reaching implications on political thought and behavior as well as on attitudes toward minorities. Under the assumption that the image of national flags is associated in memory with national ideologies, these results suggest that national ideologies can be implicitly pursued in a way that significantly affects our thoughts and behaviors.

    While the study of nationalism has received much attention throughout the social sciences and humanities, the experimental investigation of it lags behind. In this paper we review recent advances in the examination of implicit nationalism. In the first set of experiments we survey, the Palestinian, Israeli, Italian, and Russian flags were primed (or not, in the control conditions) and their effects on political thought and behavior were tested. In the second set the American or the Israeli flag was primed (or not) and prejudice toward African-Americans or Palestinians (respectively) was examined. The results of all experiments suggest that the implicit activation of national cues has far-reaching implications on political thought and behavior as well as on attitudes toward minorities. Under the assumption that the image of national flags is associated in memory with national ideologies, these results suggest that national ideologies can be implicitly pursued in a way that significantly affects our thoughts and behaviors.

    2011-01-01

    The study of opinions, their formation and change, is one of the defining topics addressed by social psychology, but in recent years other disciplines, as computer science and complexity, have addressed this challenge. Despite the flourishing of different models and theories in both fields, several key questions still remain unanswered. The aim of this paper is to challenge the current theories on opinion by putting forward a cognitively grounded model where opinions are described as specific mental representations whose main properties are put forward. A comparison with reputation will be also presented.

    Full Text Available What role does the Community of Independent States (CIS currently have in the area that was once called the Soviet Union, in particular in Russia’s so-called “near abroad”? The CIS was, to start with, little more than a liquidating committee of Soviet inheritance.This hybrid entity may be defined as a specific type of union among officially sovereign States that have few decision making mechanisms. For Russia its policy towards the “near abroad” is a priority given this country’s geostrategic interests in this area. The paperanalyzes some of the economic imperatives and the military’s participation in peacekeeping missions that have favored, up to a point, a “russification” of the CIS.

    2013-06-01

    Local public resistance can block the site-selection process, construction, and operation of nuclear waste repositories. Social science has established that the perception of risks and benefits, trust in authorities, and opinion on nuclear energy play important roles in acceptance. In particular, risk and benefit evaluations seem critical for opinion formation. However, risks and benefits have rarely been studied independently and, most often, the focus has been on the two most salient groups of proponents and opponents. The aim of this exploratory study is to examine the often-neglected majority of people holding ambivalent or indifferent opinions. We used cluster analysis to examine the sample (N = 500, mailed survey in German-speaking Switzerland) in terms of patterns of risk and benefit perception. We reveal four significantly different and plausible clusters: one cluster with high-benefit ratings in favor of a repository and one cluster with high-risk ratings opposing it; a third cluster shows ambivalence, with high ratings on both risk and benefit scales and moderate opposition, whereas a fourth cluster seems indifferent, rating risks and benefits only moderately compared to the ambivalent cluster. We conclude that a closer look at the often neglected but considerable number of people with ambivalent or indifferent opinions is necessary. Although the extreme factions of the public will most probably not change their opinion, we do not yet know how the opinion of the ambivalent and indifferent clusters might develop over time.

  20. EU-CIS joint study project 2. Radiological conditions and risk quantifications in CIS

    International Nuclear Information System (INIS)

    The radiological conditions after the Chernobyl accident in the CIS republics Ukraine, Belarus and Russia have been evaluated for the period following 1991. Differential population distributions on dose rate or surface contamination density and differential mass distributions for milk on activity concentration of 137Cs in milk have been used to calculate individual avertable and residual doses. The residual lifetime doses in the three republics with reference to the year 1991 have been calculated to be of the order of 30 mSv on average. The potential avertable individual lifetime doses are therefore less than the lifetime doses from the natural background radiation in Europe. The corresponding residual individual lifetime risks have been calculated from the European ASQRAD model to be of the order of 0.06-0.14%, depending on age at start of exposure, and assuming an effective half-life of the annual exposure of 10 years and a dose and dose rate effectiveness factor (DDREF) of 2. A risk model is being developed in Russia for the assessment of risks to the exposed populations from atmospheric nuclear weapons tests in the Semipalatinsk region (Altai region) in the forties and fifties. Calculated age-dependent risks from an acute exposure of the Altai population have been compared with results from similar calculations with the ASQRAD model and reasonable agreement has been found between the two models.

  5. Social opinion dynamics is not chaotic

    Lim, Chjan; Zhang, Weituo

    2016-08-01

    Motivated by the research on social opinion dynamics over large and dense networks, a general framework for verifying the monotonicity property of multi-agent dynamics is introduced. This allows a derivation of sociologically meaningful sufficient conditions for monotonicity that are tailor-made for social opinion dynamics, which typically have high nonlinearity. A direct consequence of monotonicity is that social opinion dynamics is nonchaotic. A key part of this framework is the definition of a partial order relation that is suitable for a large class of social opinion dynamics such as the generalized naming games. Comparisons are made to previous techniques to verify monotonicity. Using the results obtained, we extend many of the consequences of monotonicity to this class of social dynamics, including several corollaries on their asymptotic behavior, such as global convergence to consensus and tipping points of a minority fraction of zealots or leaders.

  7. Discrete Opinion Dynamics on Online Social Networks

    International Nuclear Information System (INIS)

    This paper focuses on the dynamics of binary opinions {+1, −1} on online social networks consisting of heterogeneous actors. In our model, actors update their opinions under the interplay of social influence and self- affirmation, which leads to rich dynamical behaviors on online social networks. We find that the opinion leading to the consensus features an advantage of the initially weighted fraction based on actors' strength over the other, instead of the population. For the role of specific actors, the consensus converges towards the opinion that a small fraction of high-strength actors hold, and individual diversity of self-affirmation slows down the ordering process of consensus. These indicate that high-strength actors play an essential role in opinion formation with strong social influence as well as high persistence. Further investigations show that the initial fraction of high-strength actors to dominate the evolution depends on the heterogeneity of the strength distribution, and less high-strength actors are needed in the case of a smaller exponent of power-law distribution of actors' strength. Our study provides deep insights into the role of social influence and self-affirmation on opinion formation on online social networks. (general)

    2011-09-01

    We present the result of a dual modeling of opinion networks. The model complements the agent-based opinion models by attaching to the social agent (voters) network a political opinion (party) network having its own intrinsic mechanisms of evolution. These two subnetworks form a global network, which can be either isolated from, or dependent on, the external influence. Basically, the evolution of the agent network includes link adding and deleting, with the opinion changes influenced by social validation, the political climate, the attractivity of the parties, and the interaction between them. The opinion network is initially composed of numerous nodes representing opinions or parties that are located on a one dimensional axis according to their political positions. The mechanism of evolution includes union, splitting, change of position, and attractivity, taking into account the pairwise node interaction decaying with node distance in power law. The global evolution ends in a stable distribution of the social agents over a quasistable and fluctuating stationary number of remaining parties. Empirical study on the lifetime distribution of numerous parties and vote results is carried out to verify numerical results.

  10. New energy opinion leaders' lifestyles and media usage - applying data mining decision tree analysis for UNIDO - ICHET web site users

    International Nuclear Information System (INIS)

    According to the innovation diffusion research, the innovators, opinion leaders, and diffusion agents play vital roles in promoting the acceptance of innovation. The innovators and opinion leaders must be able to cope with the high degree of uncertainty about an innovation and usually they have higher innovation-related media usage than the majority. Based on consumer behavior studies, lifestyle analysis could help researchers divide consumers into different lifestyle groups to understand and predict consumer behaviors. Lifestyle allows researchers to investigate consumers via their activities, interests and opinions instead of using demographic variables. The purpose of this research is to investigate how new energy innovators and opinion leaders' different lifestyles affect their new energy product adoption, and their media usage regarding new energy reports or promotion. In order to achieve the purposes listed above, the researchers need to locate and contact the potential innovators and opinion leaders in this field. Thus the researchers cooperate with UNIDO-ICHET to launch this survey. This cross-discipline online survey was formally launched from Aug 2005 to Oct 2006. The result of this survey successfully collected 2040 new energy innovators and opinion leaders' information. The researchers analyzed the data using SPSS statistics software and Data Mining decision tree analysis. Then the researchers divided new energy innovators into four groups: social-oriented, young modern, conservative, and show-off-oriented. They also analyzed which lifestyle groups are better targets for innovation agencies to launch innovation-related promotions or campaigns

    1996-01-01

    This paper describes investigations of CIS solar cells with ZnO window layers deposited by MOCVD. These studies have been conducted with graded absorber CIS substrates obtained from Siemens Solar. Cell fabrication involves surface preparation of the Siemens substrate, growth of 200 to 400 Å of undoped ZnO by MOCVD, deposition of a highly conducting ZnO top contact layer and deposition of a Ni/Ag collector grid. MOCVD growth of ZnO is accomplished in a SPIRE 500XT reactor by reacting a zinc adduct and tetrahydrofuran. Processing development has been conducted by forming test cells on ZnO/CIS structures by depositing thin, transparent Al contacts 2.8 mm in diameter on top of the ZnO window layer to serve as contacts. Several cells have been completed with a total area efficiency ≥11.0%, with the best result being 11.3%. The best active area efficiency is approximately 12%. Other topics discussed include current-voltage characteristics of direct ZnO/CIS cells.

    2015-08-01

    Full Text Available Although the relationship between DNA cis-regulatory sequences and gene expression has been extensively studied at steady state, how cis-regulatory sequences affect the dynamics of gene induction is not known. The dynamics of gene induction can be described by the promoter activation timescale (AcTime and amplitude threshold (AmpThr. Combining high-throughput microfluidics with quantitative time-lapse microscopy, we control the activation dynamics of the budding yeast transcription factor, Msn2, and reveal how cis-regulatory motifs in 20 promoter variants of the Msn2-target-gene SIP18 affect AcTime and AmpThr. By modulating Msn2 binding sites, we can decouple AmpThr from AcTime and switch the SIP18 promoter class from high AmpThr and slow AcTime to low AmpThr and either fast or slow AcTime. We present a model that quantitatively explains gene-induction dynamics on the basis of the Msn2-binding-site number, TATA box location, and promoter nucleosome organization. Overall, we elucidate the cis-regulatory logic underlying promoter decoding of TF dynamics.

    Following a request from the European Commission, the EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA was asked to carry out the additional assessment for ‘lactoferrin’ as a food ingredient in the context of Regulation (EC No 258/97 taking into account the comments and objections of a scientific nature raised by Member States. Bovine lactoferrin (bLF is a protein that occurs naturally in cow’s milk. The applicant intends to market bLF that is isolated from cheese whey and skimmed milk, and purified. The applicant intends to add bLF to foods for particular nutritional uses, i.e. infant and follow-on formulae, dietary food for special medical purposes, dairy products, yoghurts and yoghurt drinks, and chewing gums. According to the applicant, the high intake estimate for infants would be 1.1 g bLF per day. For adults, the applicant’s calculation estimates a mean and 97.5th percentile intake of 0.6 and 2.1 mg/kg bodyweight per day, respectively, and a mean and 97.5th percentile daily intake of about 45 mg and 150 mg, respectively. The Panel notes that the safety of bLF as a novel food ingredient has already been assessed with a favourable outcome. That evaluation was to a significant extent based on safety data on bLF produced by Morinaga. The Panel also notes that the applicant intends maximum use levels of bLF in foods which are equivalent or lower than those intended by the applicant of the previous Opinion, and that the range of foods to which it is intended to add bLF is smaller. Consequently, the estimated intake levels described for the present application are comparable for infants and lower for all other population groups. The Panel concludes that the novel food ingredient, bLF, is safe under the proposed uses and use levels.

    Full Text Available Focal demyelinated lesions, diffuse white matter (WM damage and grey matter (GM atrophy influence directly the disease progression in patients with multiple sclerosis. The aim of this study was to identify specific characteristics of GM and WM structural networks in subjects with clinically isolated syndrome (CIS in comparison to patients with early relapsing-remitting multiple sclerosis (RRMS.Twenty patients with CIS, thirty three with RRMS and forty healthy subjects were investigated using 3 T-MRI. Diffusion tensor imaging was applied, together with probabilistic tractography and fractional anisotropy (FA maps for WM and cortical thickness correlation analysis for GM, to determine the structural connectivity patterns. A network topology analysis with the aid of graph theoretical approaches was used to characterize the network at different community levels (modularity, clustering coefficient, global and local efficiencies. Finally, we applied support vector machines (SVM to automatically discriminate the two groups. .In comparison to CIS subjects, patients with RRMS were found to have increased modular connectivity and higher local clustering, highlighting increased local processing in both GM and WM. Both groups presented increased modularity and clustering coefficients in comparison to healthy controls. SVM algorithms achieved 97% accuracy using the clustering coefficient as classifier derived from GM and 65% using WM from probabilistic tractography and 67 % from modularity of FA maps to differentiate between CIS and RRMS patients. We demonstrate a clear increase of modular and local connectivity in patients with early RRMS in comparison to CIS and healthy subjects. Based only on a single anatomic scan and without a priori information, we developed an automated and investigator-independent paradigm that can accurately discriminate between patients with these clinically similar disease entities, and could thus complement the current

    Consumers increasingly rate, review and research products online. Consequently, websites containing consumer reviews are becoming targets of opinion spam. While recent work has focused primarily on manually identifiable instances of opinion spam, in this work we study deceptive opinion spam---fictitious opinions that have been deliberately written to sound authentic. Integrating work from psychology and computational linguistics, we develop and compare three approaches to detecting deceptive opinion spam, and ultimately develop a classifier that is nearly 90% accurate on our gold-standard opinion spam dataset. Based on feature analysis of our learned models, we additionally make several theoretical contributions, including revealing a relationship between deceptive opinions and imaginative writing.

    Public opinion emergencies have important effect on social activities. Recognition of special communities like opinion leaders can contribute to a comprehensive understanding of the development trend of public opinion. In this paper, a network opinion leader recognition method based on relational data was put forward, and an opinion leader recognition system integrating public opinion data acquisition module, data characteristic selection, and fusion module as well as opinion leader discovery module based on Markov Logic Networks was designed. The designed opinion leader recognition system not only can overcome the incomplete data acquisition and isolated task of traditional methods, but also can recognize opinion leaders comprehensively with considerations to multiple problems by using the relational model. Experimental results demonstrated that, compared with the traditional methods, the proposed method can provide a more accurate opinion leader recognition and has good noise immunity.

    In human societies, opinion formation is mediated by social interactions, consequently taking place on a network of relationships and at the same time influencing the structure of the network and its evolution. To investigate this coevolution of opinions and social interaction structure, we develop a dynamic agent-based network model by taking into account short range interactions like discussions between individuals, long range interactions like a sense for overall mood modulated by the attitudes of individuals, and external field corresponding to outside influence. Moreover, individual biases can be naturally taken into account. In addition, the model includes the opinion-dependent link-rewiring scheme to describe network topology coevolution with a slower time scale than that of the opinion formation. With this model, comprehensive numerical simulations and mean field calculations have been carried out and they show the importance of the separation between fast and slow time scales resulting in the network to organize as well-connected small communities of agents with the same opinion.

    The process of heat conduction (HC) has recently found application in the information filtering [Zhang et al., Phys. Rev. Lett.99, 154301 (2007)], which is of high diversity but low accuracy. The classical HC model predicts users' potential interested objects based on their interesting objects regardless to the negative opinions. In terms of the users' rating scores, we present an improved user-based HC (UHC) information model by taking into account users' positive and negative opinions. Firstly, the objects rated by users are divided into positive and negative categories, then the predicted interesting and dislike object lists are generated by the UHC model. Finally, the recommendation lists are constructed by filtering out the dislike objects from the interesting lists. By implementing the new model based on nine similarity measures, the experimental results for MovieLens and Netflix datasets show that the new model considering negative opinions could greatly enhance the accuracy, measured by the average ranking score, from 0.049 to 0.036 for Netflix and from 0.1025 to 0.0570 for Movielens dataset, reduced by 26.53% and 44.39%, respectively. Since users prefer to give positive ratings rather than negative ones, the negative opinions contain much more information than the positive ones, the negative opinions, therefore, are very important for understanding users' online collective behaviors and improving the performance of HC model.

    The present research work was performed in answer to a requirement that the CNEA-RC made to students of the Public and Institutional Relations Degree of the UES21, as a part of activities carried out in the framework of the Academic Cooperation Agreement between both institutions. In this case the students had to attend the Professional Practical course during the first semester of 2006, which included a short period in some company or organization. The Degree of Knowledge and the Opinion of the students from the Cycle of Specialization of the Province of Cordoba Educational System (ages between 15 and 17 years old), on the activities that are made in the site of CNEA-RC and DIOXITEK SA at Alta Cordoba neighborhood in Cordoba city has been analyzed. The same aspects were analyzed for Dioxitek's activities (equipment, raw materials, risk performance, etc.). Although the activities made at CNEA-RC involved during 2005/6 about 4000 students, due to the short time available for the practical part only the data of two schools located near the facilities were processed. Three aspects of the space conformed between the public and the general opinion were analyzed: the customs, the stereotypes and the attitudes of the people. These aspects were taken as the characteristics to describe to the opinions, their direction and intensity. The analysis was based on an exploratory investigation of type, characterized by its flexibility. The field work was of quantitative character. The surveys were structured with closed questions (categories of answers delimited previously on which the students must answer). For its design we used diverse sources of intelligence, such as pages of Internet, pamphlets, magazines, annual balances of the organizations, etc. The main results were the following: 1) The greater percentage of students declared to have little information on Atomic Energy. Only 4% declared to have abundant knowledge on the subject. 2) A 38% of the students indicated that

    Recently, social phenomena have received a lot of attention not only from social scientists, but also from physicists, mathematicians and computer scientists, in the emerging interdisciplinary field of complex system science. Opinion dynamics is one of the processes studied, since opinions are the drivers of human behaviour, and play a crucial role in many global challenges that our complex world and societies are facing: global financial crises, global pandemics, growth of cities, urbanisation and migration patterns, and last but not least important, climate change and environmental sustainability and protection. Opinion formation is a complex process affected by the interplay of different elements, including the individual predisposition, the influence of positive and negative peer interaction (social networks playing a crucial role in this respect), the information each individual is exposed to, and many others. Several models inspired from those in use in physics have been developed to encompass many of t...

  15. Thermodynamic state ensemble models of cis-regulation.

    Directory of Open Access Journals (Sweden)

    Marc S Sherman

    Full Text Available A major goal in computational biology is to develop models that accurately predict a gene's expression from its surrounding regulatory DNA. Here we present one class of such models, thermodynamic state ensemble models. We describe the biochemical derivation of the thermodynamic framework in simple terms, and lay out the mathematical components that comprise each model. These components include (1 the possible states of a promoter, where a state is defined as a particular arrangement of transcription factors bound to a DNA promoter, (2 the binding constants that describe the affinity of the protein-protein and protein-DNA interactions that occur in each state, and (3 whether each state is capable of transcribing. Using these components, we demonstrate how to compute a cis-regulatory function that encodes the probability of a promoter being active. Our intention is to provide enough detail so that readers with little background in thermodynamics can compose their own cis-regulatory functions. To facilitate this goal, we also describe a matrix form of the model that can be easily coded in any programming language. This formalism has great flexibility, which we show by illustrating how phenomena such as competition between transcription factors and cooperativity are readily incorporated into these models. Using this framework, we also demonstrate that Michaelis-like functions, another class of cis-regulatory models, are a subset of the thermodynamic framework with specific assumptions. By recasting Michaelis-like functions as thermodynamic functions, we emphasize the relationship between these models and delineate the specific circumstances representable by each approach. Application of thermodynamic state ensemble models is likely to be an important tool in unraveling the physical basis of combinatorial cis-regulation and in generating formalisms that accurately predict gene expression from DNA sequence.

    The CIS115 is one of the latest CMOS Imaging Sensors designed by e2v technologies, with 1504x2000 pixels on a 7 μm pitch. Each pixel in the array is a pinned photodiode with a 4T architecture, achieving an average dark current of 22 electrons pixel-1 s-1 at 21°C measured in a front-faced device. The sensor aims for high optical sensitivity by utilising e2v's back-thinning and processing capabilities, providing a sensitive silicon thickness approximately 9 μm to 12 μm thick with a tuned anti-reflective coating. The sensor operates in a rolling shutter mode incorporating reset level subtraction resulting in a mean pixel readout noise of 4.25 electrons rms. The full well has been measured to be 34000 electrons in a previous study, resulting in a dynamic range of up to 8000. These performance characteristics have led to the CIS115 being chosen for JANUS, the high-resolution and wide-angle optical camera on the JUpiter ICy moon Explorer (JUICE). The three year science phase of JUICE is in the harsh radiation environment of the Jovian magnetosphere, primarily studying Jupiter and its icy moons. Analysis of the expected radiation environment and shielding levels from the spacecraft and instrument design predict the End Of Life (EOL) displacement and ionising damage for the CIS115 to be equivalent to 1010 10 MeV protons cm-2 and 100 krad(Si) respectively. Dark current and image lag characterisation results following initial proton irradiations are presented, detailing the initial phase of space qualification of the CIS115. Results are compared to the pre-irradiation performance and the instrument specifications and further qualification plans are outlined.

  18. GRASP65 controls the cis Golgi integrity in vivo

    Directory of Open Access Journals (Sweden)

    Tineke Veenendaal

    2014-05-01

    Full Text Available GRASP65 and GRASP55 are peripheral Golgi proteins localized to cis and medial/trans cisternae, respectively. They are implicated in diverse aspects of protein transport and structure related to the Golgi complex, including the stacking of the Golgi stack and/or the linking of mammalian Golgi stacks into the Golgi ribbon. Using a mouse model, we interfered with GRASP65 by homologous recombination and confirmed its absence of expression. Surprisingly, the mice were healthy and fertile with no apparent defects in tissue, cellular or subcellular organization. Immortalized MEFs derived from the mice did not show any growth or morphological defects. However, despite the normal appearance of the Golgi ribbon, a fluorescence recovery after photobleaching assay revealed functional discontinuities specific to the cis cisternal membrane network. This leads to a strong change in the plasma membrane GSII lectin staining that was also observed in certain mutant tissues. These findings substantiate the role of GRASP65 in continuity of the cis Golgi network required for proper glycosylation, while showing that neither this continuity nor GRASP65 itself are essential for the viability of a complex organism.

    2004-02-11

    The binding of transcription factors to specific regulatory sequence elements is a primary mechanism for controlling gene transcription. Eukaryotic genes are often regulated by several transcription factors, whose binding sites are tightly clustered and form cis-regulatory modules. In this paper we present a web-server, CREME, for identifying and visualizing cis-regulatory modules in the promoter regions of a given set of potentially co-regulated genes. CREME relies on a database of putative transcription factor binding sites that have been annotated across the human genome using a library of position weight matrices and evolutionary conservation with the mouse and rat genomes. A search algorithm is applied to this dataset to identify combinations of transcription factors whose binding sites tend to co-occur in close proximity in the promoter regions of the input gene set. The identified cis-regulatory modules are statistically scored and significant combinations are reported and graphically visualized. Our web-server is available at http://creme.dcode.org/.

  20. Emotional Reactions and the Pulse of Public Opinion: Measuring the Impact of Political Events on the Sentiment of Online Discussions

    Gonzalez-Bailon, Sandra; Kaltenbrunner, Andreas

    2010-01-01

    This paper analyses changes in public opinion by tracking political discussions in which people voluntarily engage online. Unlike polls or surveys, our approach does not elicit opinions but approximates what the public thinks by analysing the discussions in which they decide to take part. We measure the emotional content of online discussions in three dimensions (valence, arousal and dominance), paying special attention to deviation around average values, which we use as a proxy for disagreement and polarisation. We show that this measurement of public opinion helps predict presidential approval rates, suggesting that there is a point of connection between online discussions (often deemed not representative of the overall population) and offline polls. We also show that this measurement provides a deeper understanding of the individual mechanisms that drive aggregated shifts in public opinion. Our data spans a period that includes two US presidential elections, the attacks of September 11, and the start of mi...

    Full Text Available Abstract Background Multiple guidelines and systematic reviews recommend sealant use to reduce caries risk. Yet, multiple reports also indicate that sealants are significantly underutilized. This study examined the knowledge, opinions, values, and practice (KOVP of dentists concerning sealant use in the southwest region of Andalusia, Spain. This is a prelude to the generation of a regional plan for improving children’s oral health in Andalusia. Methods The survey’s target population was dentists working in western Andalusia, equally distributed in the provinces of Seville, Cadiz, and Huelva (N=2,047. A convenience sample of meeting participants and meeting participant email lists (N=400 were solicited from the annual course on Community and Pediatric Dentistry. This course is required for all public health sector dentists, and is open to all private sector dentists. Information on the dentist’s KOVP of sealants was collected using four-part questionnaire with 31, 5-point Likert-scaled questions. Results The survey population demographics included 190 men (48% and 206 women (52% with an average clinical experience of 10.6 (± 8.4 years and 9.3 (± 7.5 years, respectively. A significant sex difference was observed in the distribution of place of work (urban/suburb (p=0.001, but no sex differences between working sector (public/private.

  3. The trend of the public opinion upon nuclear power generation in internet blog

    International Nuclear Information System (INIS)

    The authors pay attention to and survey internet information which is called 'blog' to grasp how nuclear power generation information is treated in internet and forms public opinion. Examples of the outcomes are as follows. 1) Numbers of blog reference will change by public opinion upon nuclear power generation. A lot of blog references about nuclear power plants are conducted when a big earthquake occurred. 2) As a feature of the report, numbers of the references against nuclear power generation exceed those which are positive for nuclear power. There are a lot of blog reports which are against nuclear power generation and easy to make readers believe that they are true even if they are based on misunderstanding. It is worried that such reports give people too much negative influence for the public opinion upon nuclear power generation. The authors survey short term trend of the internet public opinion after TEPCO's Fukushima Daiichi Power Plants Accident too. As a result, it is made clear that people's concern upon nuclear power became very high and the ratio of the supporters of nuclear power generation changed after the accident. (author)

    Full Text Available A range of factors are believed to exert a negative influence on opinions of physicians about generic drugs.The aim of this study was to survey the opinions of primary care doctors on generics, and determine the factors which may affect them. A questionnaire comprising thirty eight questions was distributed among primary care doctors working in seventy out-patient clinics of the Lodzkie province, Poland, during the period of January 1, 2010 – December 31, 2010. A total of170 of 183 participants completed the survey (average age 48.5; 70.0% women: a 92.9%response rate. While 38.8% of physicians claimed that generics were worse than brand name drugs, 54.1% considered them to be better. However, 36.5% of the doctors did not choose generics for their own use. Two key opinions were identified among the responses concerning the effectiveness of generic drugs: use of generic drugs by the physician (p<0.001, and their opinion that pharmacists do inform patients about generic drugs (p<0.05. Although existing evidence confirms that generic and brand name drugs are equally effective, many physicians doubt this, which prevents them from being used as cost effective drug therapy. In order to increase healthcare savings through the use of generics, these factors should be addressed: for example, convincing a physician to adopt generics for personal use may be an efficient way to support more cost effective treatment of his patients.

    2014-07-01

    Full Text Available Traditional education systems can sometimes become inadequate in the face of technological developments. Individuals, whose educational needs cannot be met by traditional education systems, can tend to search for alternatives and can have different demands in order to meet with these needs. These demands of the individuals can be reciprocated by managements and internet-based education methods, which remove limitations of time and space, provide facilities and equal opportunities, comply with student-centered educational approach and use computer and internet technologies, can be put into practice. Appearing before us sometimes as an alternative to the traditional education and sometimes as a support, these applications began to occupy an important place in the education systems of our era. This study, which was conducted by general survey method in view of this importance, aims to learn opinions of “masters’ students on the efficiency of distance education applications.” Survey of “Distant Education and Technologies Assessment,” developed by Aktas (2008 and adapted to Istanbul sampling by the researcher, was used in order to determine opinions. University students, who are doing masters without thesis at Social Sciences Institute Educational Administration Supervision Planning and Economics Department of Fatih University in 2013-2014 academic years, constitute the study group of the research. All of the students in the study group were reached. As a result of the study, masters’ students believe that “distance education applications” fills a very important void for individuals that experience difficulties especially in time management despite some of its inconveniencies. By looking at the results of the study, it is suggested that measures, which provide further dissemination of distance education application by will improve their technical competencies, should be taken.

    Bifenthrin (BF), as a chiral pyrethroid, is widely used to control field and household pests in China. At present, the commercial BF is a mixed compound containing cis isomers (cis-BF) including two enantiomers of 1R-cis-BF and 1S-cis-BF. In the present study, the two individual cis-BF enantiomers were separated by a preparative supercritical fluid chromatography. Then, four week-old adolescent male ICR mice were orally administered 1R-cis-BF and 1S-cis-BF separately daily for 3 weeks at doses of 0, 7.5 and 15 mg/kg/day, respectively. Results showed that the transcription status of some genes involved in cholesterol synthesis and transport as well as testosterone (T) synthesis in the testes were influenced by cis-BF enantiomers. Especially, we observed that the transcription status of key genes on the pathway of T synthesis including cytochrome P450 cholesterol side-chain cleavage enzyme (P450scc) and cytochrome P450 17α-hydroxysteroid dehydrogenase (P45017α)) were selectively altered in the testis of mice when treated with 1S-cis-BF, suggesting that it is the possible reason to explain why the lower serum T concentration in 1S-cis-BF treated group. Taken together, it concluded that both of the cis-BF enantiomers have the endocrine disruption activities, while 1S-cis-BF was higher than 1R-cis-BF in mice when exposed during the puberty. The data was helpful to understand the toxicity of cis-BF in mammals under enantiomeric level.

  19. Discrepancy and Disliking Do Not Induce Negative Opinion Shifts

    Flache, Andreas; Mäs, Michael

    2016-01-01

    Both classical social psychological theories and recent formal models of opinion differentiation and bi-polarization assign a prominent role to negative social influence. Negative influence is defined as shifts away from the opinion of others and hypothesized to be induced by discrepancy with or disliking of the source of influence. There is strong empirical support for the presence of positive social influence (a shift towards the opinion of others), but evidence that large opinion differences or disliking could trigger negative shifts is mixed. We examine positive and negative influence with controlled exposure to opinions of other individuals in one experiment and with opinion exchange in another study. Results confirm that similarities induce attraction, but results do not support that discrepancy or disliking entails negative influence. Instead, our findings suggest a robust positive linear relationship between opinion distance and opinion shifts. PMID:27333160

    Genetic engineering is a fast-moving research field that produces many achievements, including genetically modified organisms, which are used during the production of food products. Recent decades have shown that scientists, policy makers and the general public cannot reach a consensus about the benefits and hazards of genetically modified food products. Opinions are so different, and both sides are so well-grounded, that it is not easy to reach a conclusion about this scientific achievement. Nevertheless, food security is one of the main objectives of the state, which is responsible for providing safe food products to its own citizens in the marketplace. This is why states are interested in reviewing these scientific achievements, in terms of the state's national interests and the security of its citizens. This article sets forth: (1) the main advantages and disadvantages of genetically modified products; (2) the role of national legislation in the control of food security; and (3) the attitude toward genetically modified products in the national legislatures of CIS countries. Taking these points into account, the authors come to the conclusion that actual Azerbaijan law is not responding to the changes, which have taken place in recent decades, in development of the world market and technological conditions in the production of food products. This provides the basis to conclude that, in actual conditions, the rights ofAzerbaijan citizens to the safety of food products are not well protected. At the end of this article, the authors make recommendations about the necessity of amendments to the legislation in their own country, towards the goal of greater control over such products in Azerbaijan.

    The Nowak modification of the Sznajd opinion dynamics model on the square lattice assumes that with probabilities beta and gamma the opinions flip due to mass-media advertising from down to up, and vice versa. Besides, with probability alpha the Sznajd rule applies that a neighbour pair agreeing in its two opinions convinces all its six neighbours of that opinion. Our Monte Carlo simulations and mean-field theory find sharp phase transitions in the parameter space.

    We focus on non-consensus opinion models in which above a certain threshold two opinions coexist in a stable relationship. We revisit and extend the non-consensus opinion (NCO) model introduced by Shao. We generalize the NCO model by adding a weight factor W to individual's own opinion when determining its future opinion (NCOW model). We find that as W increases the minority opinion holders tend to form stable clusters with a smaller initial minority fraction compared to the NCO model. We also revisit another non-consensus opinion, the inflexible contrarian opinion (ICO) model, which introduces inflexible contrarians to model a competition between two opinions in the steady state. In the ICO model, the inflexible contrarians effectively decrease the size of the largest cluster of the rival opinion. All of the above models have previously been explored in terms of a single network. However opinions propagate not only within single networks but also between networks, we study here the opinion dynamics in couple...

    This paper reports that oil production in the Commonwealth of Independent States may dip to 7.7 million b/d next year. Robert Ebel of the Center for strategic and International Studies, Washington, D.C., made that prediction before a meeting of the National Association of Petroleum Investment Analysts. Oil and Gas Journal's latest worldwide oil production figures peg the C.I.S. volume at 8.689 million b/d last August.

    Full Text Available We report the fast cis-trans isomerization of an amine-substituted azobenzene catalyzed by graphene oxide (GO, where the amine functionality facilitates the charge transfer from azobenzene to graphene oxide in contrast to non-substituted azobenzene. This catalytic effect was not observed in stilbene analogues, which strongly supports the existence of different isomerization pathways between azobenzene and stilbene. The graphene oxide catalyzed isomerization is expected to be useful as a new photoisomerization based sensing platform complementary to GO-based fluorescence quenching methods.

    Full Text Available Objetivos: Identificar las actitudes y opiniones de los pediatras respecto al tratamiento, la prevención y la organización asistencial de la obesidad, identificar las barreras que encuentran en el tratamiento de la obesidad y las herramientas que creen más útiles para prestar una atención más efectiva. Métodos: Encuesta postal a los pediatras de atención primaria de Castilla y León, explorando la necesidad de acción frente a la obesidad, la utilidad de medidas terapéuticas y estrategias preventivas, las barreras que obstaculizan el tratamiento, las herramientas útiles para el pediatra, la eficacia propia en el tratamiento de la obesidad y la utilidad de incorporar la obesidad a la cartera de servicios. Resultados: Se consideró la obesidad como un problema de salud importante que necesita una actuación por parte de los pediatras. Esta disposición a la acción era menor entre quienes manifestaron más barreras personales. Las barreras más frecuentes procedían del medio social: disponibilidad y publicidad de determinados alimentos y bebidas, dificultades en involucrar a los padres en el tratamiento, ausencia de percepción del problema por el niño y los padres. La herramienta mejor considerada fue la formación del personal sanitario. Los pediatras se consideraban algo o poco eficaces en el tratamiento de la obesidad. La efectividad de un servicio de atención a la obesidad en atención primaria pareció ligeramente superada por la carga de trabajo que requeriría. Conclusiones: Pese a su alta disposición a la acción frente a la obesidad, los pediatras se sienten limitados debido a las barreras que encuentran, sobre todo de tipo social o cultural, y demandan más formación como una herramienta frente a la epidemia de obesidad infantil.Objectives: To identify the Spanish pediatricians' opinions and attitudes towards obesity, in relation with its treatment, prevention, and care organization, barriers they find in its treatment

    Pinotti, Roberto

    During the last three decades the general public's initial opinions about ETI and SETI changed, turning ignorance, fear and superficiality into a gradual understanding of the importance of these concepts. After a brief analysis of this changing psycho-sociological attitude, the paper provides an "estimate of the situation" about general interest for ETI and SETI, suggesting a growing awareness in today's public opinion. Science fiction movies like Close Encounters of the Third Kind and E.T. the Extra-Terrestrial and popular interest in UFOs as visitors from outer space played a major role in the average man's acceptance of the reality of extra-terrestrial life and its meaning for mankind.

    2009-04-01

    We revisit the classical model for voter dynamics in a two-party system with two basic modifications. In contrast to the original voter model studied in regular lattices, we implement the opinion formation process in a random network of agents in which interactions are no longer restricted by geographical distance. In addition, we incorporate the rapidly changing nature of the interpersonal relations in the model. At each time step, agents can update their relationships. This update is determined by their own opinion, and by their preference to make connections with individuals sharing the same opinion, or rather with opponents. In this way, the network is built in an adaptive manner, in the sense that its structure is correlated and evolves with the dynamics of the agents. The simplicity of the model allows us to examine several issues analytically. We establish criteria to determine whether consensus or polarization will be the outcome of the dynamics and on what time scales these states will be reached. In finite systems consensus is typical, while in infinite systems a disordered metastable state can emerge and persist for infinitely long time before consensus is reached.

    Proteins of the SOCS (suppressors of cytokine signalling) family are characterized by a conserved modular structure with pre-SH2 (Src homology 2), SH2 and SOCS-box domains. Several members, including CIS (cytokine-inducible SH2 protein), SOCS1 and SOCS3, are induced rapidly upon cytokine receptor activation and function in a negative-feedback loop, attenuating signalling at the receptor level. We used a recently developed mammalian two-hybrid system [MAPPIT (mammalian protein-protein interaction trap)] to analyse SOCS protein-interaction patterns in intact cells, allowing direct comparison with biological function. We find that, besides the SH2 domain, the C-terminal part of the CIS SOCS-box is required for functional interaction with the cytokine receptor motifs examined, but not with the N-terminal death domain of the TLR (Toll-like receptor) adaptor MyD88. Mutagenesis revealed that one single tyrosine residue at position 253 is a critical binding determinant. In contrast, substrate binding by the highly related SOCS2 protein, and also by SOCS1 and SOCS3, does not require their SOCS-box. PMID:16961462

    1991-01-01

    The volt-ampere (I-V) characteristics of the cis-poly (phenyl acetylene) (PPA) of cis-transoidal structure has been studied in the temperature range of 253-288K. An ITO/ PPA/ Au sandwich configuration was used for the measurements. Under an applied field of less than 105V/ cm it showed ohmic behavior, while the space charge.limited current (SCLC) was observed at applied fields above 5 × 105V/ cm. In the ohmic region a conductivity of 1.37× 10-16S/ cm was obtained at room temperature with an activation energy of 0.5 eV. These data indicate that the conduction is not intrinsic one but is the result of thermal release of trapped carriers. In fact the data in the SCLC region treated according to the theory for a single Gaussian distribution of traps gave a mean trap energy of 0.48 eV with a half-width of 0.4 eV and a total density of trapping states of 5× 1016/ cm3 .

    Social dynamic opinion models have been widely studied to understand how interactions among individuals cause opinions to evolve. Most opinion models that utilize spin interaction models usually produce a consensus steady state in which only one opinion exists. Because in reality different opinions usually coexist, we focus on non-consensus opinion models in which above a certain threshold two opinions coexist in a stable relationship. We revisit and extend the non-consensus opinion (NCO) model introduced by Shao et al. (Phys. Rev. Lett. 103:01870, 2009). The NCO model in random networks displays a second order phase transition that belongs to regular mean field percolation and is characterized by the appearance (above a certain threshold) of a large spanning cluster of the minority opinion. We generalize the NCO model by adding a weight factor W to each individual's original opinion when determining their future opinion (NCO W model). We find that as W increases the minority opinion holders tend to form stable clusters with a smaller initial minority fraction than in the NCO model. We also revisit another non-consensus opinion model based on the NCO model, the inflexible contrarian opinion (ICO) model (Li et al. in Phys. Rev. E 84:066101, 2011), which introduces inflexible contrarians to model the competition between two opinions in a steady state. Inflexible contrarians are individuals that never change their original opinion but may influence the opinions of others. To place the inflexible contrarians in the ICO model we use two different strategies, random placement and one in which high-degree nodes are targeted. The inflexible contrarians effectively decrease the size of the largest rival-opinion cluster in both strategies, but the effect is more pronounced under the targeted method. All of the above models have previously been explored in terms of a single network, but human communities are usually interconnected, not isolated. Because opinions propagate not

    2016-01-01

    We investigate opinion formation in a kinetic exchange opinion model, where opinions are represented by numbers in the real interval $[-1,1]$ and agents are typified by the individual degree of conviction about the opinion that they support. Opinions evolve through pairwise interactions governed by competitive positive and negative couplings, that promote imitation and dissent, respectively. The model contemplates also another type of nonconformity such that agents can occasionally choose their opinions independently of the interactions with other agents. The steady states of the model as a function of the parameters that describe conviction, dissent and independence are analyzed, with particular emphasis on the emergence of extreme opinions. Then, we characterize the possible ordered and disordered phases and the occurrence or suppression of phase transitions that arise spontaneously due to the disorder introduced by the heterogeneity of the agents and/or their interactions.

    Full Text Available This study investigates the effect of auditor-management alignment on audit opinion over the period 2003- 2011 on 81 firms listed on the Tehran Stock Exchange using logistic regression analysis. Results indicate that in companies with auditor-management alignment, auditor change level is low. In addition, the results indicate there is no relationship between auditor-management alignment, debt ratio, ownership percentage, firm size and auditor change with unqualified audit opinion. However, research evidences show that auditor's opinion type at previous year, audit fees, auditor type and return on assets ratio influence unqualified audit opinion. Among above variables, auditor's opinion types at previous year, audit fees and return on assets ratio have direct relationship with unqualified audit opinion but auditor type has a negative and inverse relationship with unqualified audit opinion.

    We propose the PageRank model of opinion formation and investigate its rich properties on real directed networks of Universities of Cambridge and Oxford, LiveJournal and Twitter. In this model the opinion formation of linked electors is weighted with their PageRank probability. We find that the society elite, corresponding to the top PageRank nodes, can impose its opinion to a significant fraction of the society. However, for a homogeneous distribution of two opinions there exists a bistability range of opinions which depends on a conformist parameter characterizing the opinion formation. We find that LiveJournal and Twitter networks have a stronger tendency to a totalitar opinion formation. We also analyze the Sznajd model generalized for scale-free networks with the weighted PageRank vote of electors.

    Full Text Available The goal of the article is to determine the place and role of opinion giving services in consumer behaviours. The discussion is conducted around the thesis saying that in the information society, opinion giving services constitute an important source of information for consumers in the process of selecting and purchasing both products and services. In the article the research approach based on the theoretical and empirical examinations was presented. The discussion starts with presenting a defi nition and types of opinion giving services which constitute the base for the characteristics of activities and usefulness of web portals collecting consumers opinions. The use of opinion giving services provided in the purchase process was evaluated. An essential interest in other consumers opinions, placed in Internet, was observed together with perceiving them as credible. Positive assessment of the functionality of opinion giving services was noticed.

    As scientists we like to think that modern societies and their members base their views, opinions and behaviour on scientific facts. This is not necessarily the case, even though we are all (over-) exposed to information flow through various channels of media, i.e. newspapers, television, radio, internet, and web. It is thought that this is mainly due to the conflicting information on the mass media and to the individual attitude (formed by cultural, educational and environmental factors), that is, one external factor and another personal factor. In this paper we will investigate the dynamical development of opinion in a small population of agents by means of a computational model of opinion formation in a co-evolving network of socially linked agents. The personal and external factors are taken into account by assigning an individual attitude parameter to each agent, and by subjecting all to an external but homogeneous field to simulate the effect of the media. We then adjust the field strength in the model by using actual data on scientific perception surveys carried out in two different populations, which allow us to compare two different societies. We interpret the model findings with the aid of simple mean field calculations. Our results suggest that scientifically sound concepts are more difficult to acquire than concepts not validated by science, since opposing individuals organize themselves in close communities that prevent opinion consensus.

    The conclusions that can be drawn from public opinion polls depend a great deal on what usually does not appear on the newspaper page or television screen. Subtle biases can result from the population interviewed, the time of day individuals were called, how a particular question was asked, or how the answer was interpreted. Examples are the 1961 Gallop Poll, the survey done for Rockwell International by the firm of Yankelovich, Skelly and White/Clancy Shulman, and the one done by Jon D. Miller of the International Center for the Advancement of Scientific Literacy. There is more to learn from opinion polls than that a good proportion of adult Americans support the space program. We can learn that social and economic security are not competing goals with space, but interdependent goals. If we want to increase public support for space, we must increase the number of Americans who have the economic freedom to take an interest in something besides getting by, day after day. We can also learn that the majority of those who support the space program can distinguish between the bread and circuses of space travel. They are content to experience extraordinary adventures in the movie theaters; for their tax dollars they want real return in expended scientific knowledge and understanding. Finally, we can learn that we need to increase that return, not just for scientific careers, but for the ordinary people who pay our bills and for their children, our children. Ultimately, the space program is for them, as all investments in the future must be.

  20. Radiologic reports : attitudes, preferred type, and opinion of referring physicians

    International Nuclear Information System (INIS)

    To determine referring physicians' general attitudes, preferred reporting types, and opinions on radiologic reports. A survey questionnaire was distributed to the 315 staff and residents of four university hospitals with 400 to 800 beds, and a total of 228 physicians responded. The questionnaire aimed to determine of the general attitude of referring physicians to radiologic reports, the type of report they preferred, and other opinions and suggestions. The responses elicited, as well as discrepancies among residents, staff, internist, and surgeons, were analyzed. Most referring physicians replied that they read an entire report regardless of its length, and the second majority read the conclusion first and then the remainder of the report only if clarification was required. With regard to report length, physicians answered that reports describing the findings of conventional radiography were often too short, while those dealing with MRI were verbose. The majority experienced occasional confusion when reading a report, the major cause being grammatical errors and incomprehensible sentence structure. When confused, most physicians consulted the radiologist ; staff showed a greater inclination than residents to pursue this option. Most physicians preferred brief phrases or telegraphic-style sentences to a style which stressed completeness and detail, a preference which was statistically higher among residents than staff. Whereas physicians favored a brief radiologic report in cases of normal radiologic findings, conventional radiologic studies or no clinical findings, they wished to see a more detailed report in cases of abnormal radiologic findings, specific radiologic studies (special radiographs, US, CT, or MRI), or positive clinical findings. This need for more detail was expressed more frequently by internists than by surgeons. If implemented, the results of this study can be expected to enhance the quality and comprehensibility of radiologic reports, and may

Now, it is no longer the Soviet Union, but the Commonwealth of Independent States (CIS). We are now making wholesale unilateral cuts in our defense structure as the CIS is viewed as our friend and no longer the Evil Empire. We are supplying the CIS with food, loan credits, and even offering assistance to help them destroy nuclear weapons. Even though the world has changed, the CIS remains the only country on the face of the earth capable of destroying the United States in a nuclear holocaust.

    Resveratrol (E-3,5,4’-trihydroxystilbene) is a polyphenol found in red wine that has been shown to have multiple anti-cancer properties. Although cis (Z) and trans (E) isomers of resveratrol occur in nature, the cis form is not biologically active. However, methylation at key positions of the cis form results in more potent anti-cancer properties. This study determined that synthetic cis-polymethoxystilbenes (methylated analogues of cis-resveratrol) inhibited cancer-related phenotypes of metastatic B16 F10 and non-metastatic B16 F1 mouse melanoma cells. In contrast with cis or trans-resveratrol and trans-polymethoxystilbene which were ineffective at 10 μM, cis-polymethoxystilbenes inhibited motility and proliferation of melanoma cells with low micromolar specificity (IC50 <10 μM). Inhibitory effects by cis-polymethoxystilbenes were significantly stronger with B16 F10 cells and were accompanied by decreased expression of β-tubulin and pleckstrin homology domain-interacting protein, a marker of metastatic B16 cells. Thus, cis-polymethoxystilbenes have potential as chemotherapeutic agents for metastatic melanoma. PMID:25567208

    A dynamical model with continuous opinion is proposed to study how the speech order and the topology of directed social network affect the opinion formation of free speech. In the model, agents express their opinions one by one with random order (RO) or probability order (PO), other agents paying attentions to the speaking agent, receive provider's opinion, update their opinions and then express their new opinions in their turns. It is proved that with the same agent j repeats its opinion more, other agents who pay their attentions to j and include j's opinion in their confidence level at initial time, will continue approaching j's opinion. Simulation results reveal that on directed scale-free network: (1) the model for PO forms fewer opinion clusters, larger maximum cluster (MC), smaller standard deviation (SD), and needs less waiting time to reach a middle level of consensus than RO; (2) as the parameter of scale-free degree distribution decreases or the confidence level increases, the results often get better for both speech orders; (3) the differences between PO and RO get smaller as the size of network decreases.

    When opinions, behaviors or ideas diffuse within a population, some are invariably stickier than others. The stickier the opinion, behavior or idea, the greater is an individual's inertia to replace it with an alternative. Here we study the effect of stickiness of opinions in a two-opinion model, where individuals change their opinion only after a certain number of consecutive encounters with the alternative opinion. Assuming that one opinion has a fixed stickiness, we investigate how the critical size of the competing opinion required to tip over the entire population varies as a function of the competing opinion's stickiness. We analyze this scenario for the case of a complete-graph topology through simulations, and through a semi-analytical approach which yields an upper bound for the critical minority size. We present analogous simulation results for the case of the Erd\\H{o}s-R\\'enyi random network.

    International Nuclear Information System (INIS)

    The ability to survive in a competitive electricity market is a function of the ability of a service provider to deliver superior levels of customer service and develop new and innovative products and services. More and more, the foundation of these new services and products is the customer information system which has the capability to provide vast amounts of usage data and billing information; access to this data enables service providers to introduce new and innovative services and implement targeted marketing initiatives. Recent trend by progressive electricity providers appears to be to outsource specific information technology functions such as customer information systems (CIS) as a way to minimize capital investment, take advantage of leading edge technologies and leverage the expertise of niche service providers. Advantages of outsourcing, and factors important in the selection of an outsourcing partner are discussed

  9. Radiation safety and formation of public opinion

    Full text: Team-administrative system of long years has been a reason of environmental pollution and health consequences and still does. This includes soil pollution with pesticides, ecological condition of micro and macro flora of the Caspian Sea, soil pollution with oil, deforestation and etc. Scientists and environmental NGOs have given some information to public and public opinion has already been formed on this issue. But public opinion is not necessarily formed on radiation - the most important and invisible problem. The reason of this is that radiation danger has been hidden as a closed theme from the public. After the soviet collapse this problem is also being revealed. Number of NGOs have held the seminar on this issue and given some information to public. The researches cover the following problems:To hold the public monitoring in the fields polluted with oil and separate it from the other fields by determining the fields polluted with radiation. To take measures in order to prevent public entrance to these fields; To inform about the usage of radiation based equipment in the industrial fields and to hold the regular monitoring; To advertise the differential signs of radiation sources in the city landfill and other polluted zones; To broaden the advocacy on ultraviolet rays and their influence to human health; To disseminate the brochures and advertisement papers on high technical radiation and their influence to human health; To analyze the radio environmental condition around the Gabala Radar Station; To advocate the possible radiation danger in using the x-ray and other medical equipment; Analyze the possible radon danger in shipping materials; To create the idea on possible transition of radioactive gases and elements from neighbor countries; Creation of idea on possible danger around the high voltage. The formation of public opinion on mentioned problem will depend on combining the scientists' and NGOs activities

  10. Patterns of cis regulatory variation in diverse human populations.

    Barbara E Stranger

    Full Text Available The genetic basis of gene expression variation has long been studied with the aim to understand the landscape of regulatory variants, but also more recently to assist in the interpretation and elucidation of disease signals. To date, many studies have looked in specific tissues and population-based samples, but there has been limited assessment of the degree of inter-population variability in regulatory variation. We analyzed genome-wide gene expression in lymphoblastoid cell lines from a total of 726 individuals from 8 global populations from the HapMap3 project and correlated gene expression levels with HapMap3 SNPs located in cis to the genes. We describe the influence of ancestry on gene expression levels within and between these diverse human populations and uncover a non-negligible impact on global patterns of gene expression. We further dissect the specific functional pathways differentiated between populations. We also identify 5,691 expression quantitative trait loci (eQTLs after controlling for both non-genetic factors and population admixture and observe that half of the cis-eQTLs are replicated in one or more of the populations. We highlight patterns of eQTL-sharing between populations, which are partially determined by population genetic relatedness, and discover significant sharing of eQTL effects between Asians, European-admixed, and African subpopulations. Specifically, we observe that both the effect size and the direction of effect for eQTLs are highly conserved across populations. We observe an increasing proximity of eQTLs toward the transcription start site as sharing of eQTLs among populations increases, highlighting that variants close to TSS have stronger effects and therefore are more likely to be detected across a wider panel of populations. Together these results offer a unique picture and resource of the degree of differentiation among human populations in functional regulatory variation and provide an estimate for

  11. Modeling an evolutionary conserved circadian cis-element.

    2008-02-01

    Full Text Available Circadian oscillator networks rely on a transcriptional activator called CLOCK/CYCLE (CLK/CYC in insects and CLOCK/BMAL1 or NPAS2/BMAL1 in mammals. Identifying the targets of this heterodimeric basic-helix-loop-helix (bHLH transcription factor poses challenges and it has been difficult to decipher its specific sequence affinity beyond a canonical E-box motif, except perhaps for some flanking bases contributing weakly to the binding energy. Thus, no good computational model presently exists for predicting CLK/CYC, CLOCK/BMAL1, or NPAS2/BMAL1 targets. Here, we use a comparative genomics approach and first study the conservation properties of the best-known circadian enhancer: a 69-bp element upstream of the Drosophila melanogaster period gene. This fragment shows a signal involving the presence of two closely spaced E-box-like motifs, a configuration that we can also detect in the other four prominent CLK/CYC target genes in flies: timeless, vrille, Pdp1, and cwo. This allows for the training of a probabilistic sequence model that we test using functional genomics datasets. We find that the predicted sequences are overrepresented in promoters of genes induced in a recent study by a glucocorticoid receptor-CLK fusion protein. We then scanned the mouse genome with the fly model and found that many known CLOCK/BMAL1 targets harbor sequences matching our consensus. Moreover, the phase of predicted cyclers in liver agreed with known CLOCK/BMAL1 regulation. Taken together, we built a predictive model for CLK/CYC or CLOCK/BMAL1-bound cis-enhancers through the integration of comparative and functional genomics data. Finally, a deeper phylogenetic analysis reveals that the link between the CLOCK/BMAL1 complex and the circadian cis-element dates back to before insects and vertebrates diverged.

The author’s Questionnaire for Evaluating the Electronic Supervision System was used as a tool, which also contained a lie scale. The respondents’ mood was also controlled. To verify the formulated hypotheses, the method of diagnostic survey was adopted and methods of statistical and comparative analysis. Factor analysis demonstrated that the perception of the Electronic Supervision System does not come down to a unitary opinionopinions about ESS are an incoherent construct, in which we can single out three factors: Negative Evaluations, Positive Evaluations and Stigmatization. It turned out that “non-elite” prisoners have a much higher intensity of Negative Evaluations of ESS than “elite” prisoners. In terms of Positive Evaluations and sensed Stigmatization, there were no significant differences found between non-elite and elite groups.

    2013-10-01

    Human interactions give rise to the formation of different kinds of opinions in a society. The study of formations and dynamics of opinions has been one of the most important areas in social physics. The opinion dynamics and associated social structure leads to decision making or so called opinion consensus. Opinion formation is a process of collective intelligence evolving from the integrative tendencies of social influence with the disintegrative effects of individualisation, and therefore could be exploited for developing search strategies. Here, we demonstrate that human opinion dynamics can be utilised to solve complex mathematical optimization problems. The results have been compared with a standard algorithm inspired from bird flocking behaviour and the comparison proves the efficacy of the proposed approach in general. Our investigation may open new avenues towards understanding the collective decision making.

    Ngampruetikorn, V

    2015-01-01

    With the advent of online networks, societies are substantially more connected with individual members able to easily modify and maintain their own social links. Here, we show that active network maintenance exposes agents to confirmation bias, the tendency to confirm one's beliefs, and we explore how this affects collective opinion formation. We introduce a model of binary opinion dynamics on a complex network with fast, stochastic rewiring and show that confirmation bias induces a segregation of individuals with different opinions. We use the dynamics of global opinion to generally categorize opinion update rules and find that confirmation bias always stabilizes the consensus state. Finally, we show that the time to reach consensus has a non-monotonic dependence on the magnitude of the bias, suggesting a novel avenue for large-scale opinion engineering.

    We present the result of a dual modeling of opinion network. The model complements the agent-based opinion models by attaching to the social agent (voters) network a political opinion (party) network having its own intrinsic mechanisms of evolution. These two sub-networks form a global network which can be either isolated from or dependent on the external influence. Basically, the evolution of the agent network includes link adding and deleting, the opinion changes influenced by social validation, the political climate, the attractivity of the parties and the interaction between them. The opinion network is initially composed of numerous nodes representing opinions or parties which are located on a one dimensional axis according to their political positions. The mechanism of evolution includes union, splitting, change of position and of attractivity, taken into account the pairwise node interaction decaying with node distance in power law. The global evolution ends in a stable distribution of the social agent...

    A physical description of an opinion evolution is conducted based on the Hamilton-Jacobi equation derived from a generalized potential and the corresponding Langevin equation. The investigation mainly focuses on the heterogeneities such as age, connection circle and overall quality of the participants involved in the opinion exchange process. The evolutionary patterns of opinion can be described by solution of the Hamilton-Jacobi equation, information entropy. The results show that the overall qualities of the participants play critical roles in forming an opinion. The higher the overall quality is, the easier the consensus can reach. The solution also demonstrates that the age and the connection circle of the agents play equally important roles in forming an opinion. The essence of the age, overall quality, and connection circle corresponds to the maturity of thought (opinion inertia), reason and intelligence, influence strength of the environment, respectively. So the information entropy distributes in the ...

In this study, a cis-DIDP carrier system based on micro-sized stearic acid was prepared by an emulsion solvent evaporation method. The maximum drug loading capacity of cis-DIDP-loaded solid lipid nanoparticles was 22.03%, and their encapsulation efficiency was 97.24%. In vitro drug release in phosphate-buffered saline (pH =7.4 at 37.5°C exhibited a unique two-stage process, which could prove beneficial for patients with tumors and malignancies. MTT (3-[4,5-dimethylthiazol-2-yl]-2, 5-diphenyltetrazolium bromide assay results showed that cis-DIDP released from cis-DIDP-loaded solid lipid nanoparticles had better inhibition activity than cis-DIDP that had not been loaded.

    The primary photochemical process of the visual function has been investigated using the three crystallographic models, 11-cis-rhodopsin, all-trans-bathorhodopsin, and the artificial isomeric 9-cis-rhodopsin. Detailed examination of the atomic displacements and dihedral angle changes of the retinal chromophore involved in the interconversion among these isomers suggests the mechanism of isomerization efficiency.

    cis-Prenyltransferases (cis-PTs) constitute a large family of enzymes conserved during evolution and present in all domains of life. cis-PTs catalyze consecutive condensation reactions of allylic diphosphate acceptor with isopentenyl diphosphate (IPP) in the cis (Z) configuration to generate linear polyprenyl diphosphate. The chain lengths of isoprenoid carbon skeletons vary widely from neryl pyrophosphate (C10) to natural rubber (C>10,000). The homo-dimeric bacterial enzyme, undecaprenyl diphosphate synthase (UPPS), has been structurally and mechanistically characterized in great detail and serves as a model for understanding the mode of action of eukaryotic cis-PTs. However, recent experiments have revealed that mammals, fungal, and long-chain plant cis-PTs are heteromeric enzymes composed of two distantly related subunits. In this review, the classification, function, and evolution of cis-PTs will be discussed with a special emphasis on the role of the newly described NgBR/Nus1 subunit and its plants' orthologs as essential, structural components of the cis-PTs activity.

    Full Text Available Background: Several epidemiological studies have shown that diets rich in carotenoids are associated with a reduced risk of cardiovascular disease. However, administration of synthetic all-trans -carotene was reported to have no effect on cardiovascular disease. We previously showed that the 9-cis -carotene-rich powder of the alga Dunaliella bardawil inhibits atherogenesis and reduces plasma non-HDL cholesterol levels in mice. Context and purpose of this study: We sought to study whether isolated 9-cis -carotene inhibits atherogenesis in a murine model of atherosclerosis. Results: Twelve-week-old female LDL receptor knockout mice (LDLR-/- were pretreated for 2 weeks with regular chow diet fortified with the alga Dunaliella powder, 9-cis β-carotene isomer, all-trans β-carotene isomer, or 9-cis retinoic acid, followed by 10 weeks of a high-fat diet with the same fortifications. In contrast to Dunaliella, 9-cis β-carotene did not inhibit the high fat dietinduced elevation of plasma cholesterol. In addition, diet fortification with Dunaliella powder, β-carotene isomers, or 9-cis retinoic acid did not change the plasma retinol or retinoic acid levels.Nevertheless, 9-cis β-carotene significantly inhibited atherogenesis compared to the control mice (39% reduction. Conclusions: The results suggest that 9-cis β-carotene should be considered as an antiatherogenic agent in the human diet

    We introduce a contagion-like model for competing opinions that includes dynamic resistance to alternative opinions. We show that this model can describe candidate vote distributions, spatial vote correlations, and slow opinion consensus with sensible parameter values. This may suggest that all these distinct behaviors, previously understood using distinct models, may be different aspects of a more unified model of human behavior introduced in this paper.

    We introduce a general contagionlike model for competing opinions that includes dynamic resistance to alternative opinions. We show that this model can describe candidate vote distributions, spatial vote correlations, and a slow approach to opinion consensus with sensible parameter values. These empirical properties of large group dynamics, previously understood using distinct models, may be different aspects of human behavior that can be captured by a more unified model, such as the one introduced in this paper.

    Schulze, Christian

    In this modification of the Sznajd consensus model on the square lattice, two people of arbitrary distance who agree in their opinions convince their nearest neighbors of this opinion. Similarly to the mean field theory of Slanina and Lavicka, the times needed to reach consensus are distributed exponentially and are quite small. The width of the phase transition vanishes reciprocally to the linear lattice dimension. Advertising has effects independent of the system size. For more than two opinions, three opinions reach a consensus in roughly half of the samples, and four only rarely and only for small lattices. Up to 109 agents were simulated.

    An individual’s opinion on an issue is greatly impacted by others in his or her social network. Most people are open-minded and ready to change their opinion when presented evidence; however, some are zealots or inflexibles, that is, individuals who refuse to change their opinion while staunchly advocating an opinion in hopes of convincing others. Zealotry is present in opinions of significant personal investment, such as political, religious or corporate affiliation; it tends to be less commonplace in opinions involving rumors or fashion trends. In this paper, we examine the effect that zealots have in a population whose opinion dynamics obey the naming game model. We present numerical and analytical results about the number and nature of steady state solutions, demonstrating the existence of a bifurcation in the space of zealot fractions. Our analysis indicates conditions under which a minority zealot opinion ultimately prevails, and conditions under which neither opinion attains a majority. We also present numerical and simulation analysis of finite populations and on networks with partial connectivity.

  17. Harry and Louise and health care reform: romancing public opinion.

    2001-12-01

    The question whether the "Harry and Louise" campaign ads, sponsored by the Health Insurance Association of America (HIAA) during the 1993-1994 health care reform debate, influenced public opinion has particular relevance today since interest groups are increasingly choosing commercial-style mass media campaigns to sway public opinion about health policy issues. Our study revisits the issue of the Harry and Louise campaign's influence on public opinion, comparing the ad campaign's messages to changes in opinion about health care reform over a twenty-six-month period in Oklahoma. Looking at the overall trends just prior to the introduction of the Harry and Louise campaign, public opinion was going in the "wrong" direction, from the HIAA perspective. Moreover, public opinion continued in the wrong direction until the mid-point of the campaign. However, in either the turning point of the campaign in terms of message content and tone or in the lag period following it, public opinion reversed on each health reform issue and returned to pre-campaign levels. It appears from these findings that the campaign captured public opinion when support for issues that were unfavorable to HIAA members was increasing and turned public opinion back to pre-campaign levels. The campaign may result in many more such marriages of political interest groups and commercial advertisers for the purpose of demobilizing public support for health policy initiatives that are unfavorable to special interests.

  20. Correlation between information diffusion and opinion evolution on social media

    International Nuclear Information System (INIS)

    Information diffusion and opinion evolution are often treated as two independent processes. Opinion models assume the topic reaches each agent and agents initially have their own ideas. In fact, the processes of information diffusion and opinion evolution often intertwine with each other. Whether the influence between these two processes plays a role in the system state is unclear. In this paper, we collected more than one million real data from a well-known social platform, and analysed large-scale user diffusion behaviour and opinion formation. We found that user inter-event time follows a two-scaling power-law distribution with two different power exponents. Public opinion stabilizes quickly and evolves toward the direction of convergence, but the consensus state is prevented by a few opponents. We propose a three-state opinion model accompanied by information diffusion. Agents form and exchange their opinions during information diffusion. Conversely, agents' opinions also influence their diffusion actions. Simulations show that the model with a correlation of the two processes produces similar statistical characteristics as empirical results. A fast epidemic process drives individual opinions to converge more obviously. Unlike previous epidemic models, the number of infected agents does not always increase with the update rate, but has a peak with an intermediate value of the rate. (paper)

  1. Biologically active cis-cinnamic acid occurs naturally in Brassica parachinensis

    Institute of Scientific and Technical Information of China (English)

    2003-01-01

    The biologically active cis-cinnamic acid (cis-CA) has been perceived as a synthetic plant growth regulator for decades. However, in the present study, we found that cis-CA actually exists as a naturally occurring compound in a Brassica plant. This natural growth- regulating substance presents in both the sunlight-irradiated leaf tissue and the non-irradiated root tissue. The concentrations of cis-CA in both tissues are comparable to the biologically effective levels of those major plant hormones. The presence of cis-CA in root tissue suggests that it may be produced through both light-dependent and -independent path- ways or it can be transported from a plant organ to another.

  2. Possible mechanism for differences in sensitivity to cis-platinum in human prostate tumor cell lines

    International Nuclear Information System (INIS)

    Two human prostate tumor cell lines which exhibit a 2.4-fold difference in sensitivity to cis-platinum (cis-191Pt) were found to possess slightly different sulphydryl contents, and the presence of a metallothionein-like zinc-binding protein was demonstrated in the line exhibiting relative resistance to cis-191Pt. Although these factors have been postulated to play a role in the mechanism(s) of resistance to cis-191Pt in other cell types, preliminary data in this report suggest that differences found in drug uptake and subsequent binding to DNA are most likely responsible for variations in cis-191Pt sensitivity displayed by these prostate tumor cell lines

    Objective: The aim of our study was to comprehensively access current status of radiotherapy physicians' opinions in post-mastectomy radiotherapy (PMRT) for breast cancer in Guangdong province. Methods: From June 2007 to June 2008, questionnaires on the clinical value, sequencing with chemotherapy and endocrine therapy, indications and irradiated targets for PMRT were sent to physicians of all radiotherapy departments registering at Radiotherapy Professional Committee of Guangdong Anti-cancer Association. Results: There were 126 physicians joining this investigation. Proportions of physicians who accepted the views that PMRT could merely improve local control or can improve both local control and overall survival were 100% and 25.2%. The most common sequences of PMRT and chemotherapy or endocrine therapy were “sandwich” and sequential modes, performed 46.9% and 59.5% respectively. The median interval of surgery and PM RT was 8 weeks. Propoortions of physicians who accepted T3-4 diseases, or four or more axillary lymph nodes metastasis, or T1-2 with 1-3 positive lymph nodes, or T1-2N0 with primary tumor located in the center or inner quadrant as the indications of PMRT were 97.6%, 100%, 46.8%, 13.5%, respectively. Proportions of physicians who accepted chest wall, supraclavicular region,internal mammary chain or axilla as irradiated targets were 86.5%, 100%, 49.2% and 38.9% respectively. Conclusion: For Radiotherapy physicians of Guangdong Province, there is still lacking of consensus in the opinions of whether PMRT can improve survival, and optimal sequencing with chemotherapy or endocrine therapy, and how to make decision for patients with T1-2 with 1-3 positive lymph nodes, and rational irradiated targets, which requires advanced professional training for physicians and further prospective clinical trial evidences to guide clinical practice.

    Full Text Available Gene expression is a heritable cellular phenotype that defines the function of a cell and can lead to diseases in case of misregulation. In order to detect genetic variations affecting gene expression, we performed association analysis of single nucleotide polymorphisms (SNPs and copy number variants (CNVs with gene expression measured in 869 lymphoblastoid cell lines of the Avon Longitudinal Study of Parents and Children (ALSPAC cohort in cis and in trans. We discovered that 3,534 genes (false discovery rate (FDR = 5% are affected by an expression quantitative trait locus (eQTL in cis and 48 genes are affected in trans. We observed that CNVs are more likely to be eQTLs than SNPs. In addition, we found that variants associated to complex traits and diseases are enriched for trans-eQTLs and that trans-eQTLs are enriched for cis-eQTLs. As a variant affecting both a gene in cis and in trans suggests that the cis gene is functionally linked to the trans gene expression, we looked specifically for trans effects of cis-eQTLs. We discovered that 26 cis-eQTLs are associated to 92 genes in trans with the cis-eQTLs of the transcriptions factors BATF3 and HMX2 affecting the most genes. We then explored if the variation of the level of expression of the cis genes were causally affecting the level of expression of the trans genes and discovered several causal relationships between variation in the level of expression of the cis gene and variation of the level of expression of the trans gene. This analysis shows that a large sample size allows the discovery of secondary effects of human variations on gene expression that can be used to construct short directed gene regulatory networks.

    The photosensitized cis/trans isomerization of a series of 1-(1-propenyl)cycloalkenes is reported. A plot of the photostationary state trans/cis ratio vs the sensitizer triplet energy for 1-(1-propenyl)cyclopentene shows a constant trans/cis ratio of {approx} 1.0 with high-energy sensitizers (E{sub T} > 61 kcal/mol). The plot shows one maxima at E{sub T} {approx} 55 kcal/mol with low-energy sensitizers (E{sub T} < 61 kcal/mol). This type of plot is very similar to those obtained with acyclic dienes such as piperylene. The 1-(1-propenyl)cyclohexene system shows a similar plot with high-energy sensitizers, but with low-energy sensitizers this system shows two maxima occurring at 56 and 47 kcal/mol, respectively. This double-maxima plot is rationalized by an unusually low trans/cis decay ratio for the s-cis relaxed triplet state of the 1-(1-propenyl)cyclohexene system. This double maxima is not observed in other diene systems due to a high trans/cis decay ratio for their s-cis relaxed triplet states. The photosensitized cis/trans isomerization of 2-ethylidene-10-methyl-1(9)-octalin was also studied as a model for a conformationally locked s-trans system. The 1-(1-propenyl)cycloheptene system undergoes photosensitized cis/trans isomerization, but photostationary cis/trans isomerization data could not be obtained due to a very efficient photosensitized dimerization of this diene system.

    Full Text Available Cholesterol efflux from macrophages is a key process in reverse cholesterol transport and, therefore, might inhibit atherogenesis. 9-cis-β-carotene (9-cis-βc is a precursor for 9-cis-retinoic-acid (9-cis-RA, which regulates macrophage cholesterol efflux. Our objective was to assess whether 9-cis-βc increases macrophage cholesterol efflux and induces the expression of cholesterol transporters. Enrichment of a mouse diet with βc from the alga Dunaliella led to βc accumulation in peritoneal macrophages. 9-cis-βc increased the mRNA levels of CYP26B1, an enzyme that regulates RA cellular levels, indicating the formation of RA from βc in RAW264.7 macrophages. Furthermore, 9-cis-βc, as well as all-trans-βc, significantly increased cholesterol efflux to high-density lipoprotein (HDL by 50% in RAW264.7 macrophages. Likewise, food fortification with 9-cis-βc augmented cholesterol efflux from macrophages ex vivo. 9-cis-βc increased both the mRNA and protein levels of ABCA1 and apolipoprotein E (APOE and the mRNA level of ABCG1. Our study shows, for the first time, that 9-cis-βc from the diet accumulates in peritoneal macrophages and increases cholesterol efflux to HDL. These effects might be ascribed to transcriptional induction of ABCA1, ABCG1, and APOE. These results highlight the beneficial effect of βc in inhibition of atherosclerosis by improving cholesterol efflux from macrophages.

    Full Text Available Recently there has, been growing a increase in consumption of poultry meat in Poland. The most important material for slaughter poultry are broilers. Among factors that influence rising demand for poultry meat are: low price, availability of raw materials and promotional campaigns of safe nutrition. Its nutritional and sensory value makes it a choice product. University students are a specific group that has aroused the interest of nutritionists. The students’ lifestyle is characterised by high active social life and intense responsibilities, which ought to be augmented with a carefully chosen diet. The youth do not only have significant impact on the family purchasing decisions but display a strong purchasing power due to financial resources at their disposal and would in the future become mature and rational consumers. The article lists factors that determine purchasing needs, reasons for choice of markets and the consumption frequency of broiler meat. The feeling of lack of other products coupled with current sales promotions were, in the opinion of the students surveyed, often responsible for the decision to purchase of broiler chicken meat. Low price and the ease of preparation were also key reasons for the choice of this meat product. Responding students noted that skinless chicken breast fillet was most commonly consumed.

    The views held by health experts on certain topics may differ drastically from what appears to be obvious from observations in daily living or public opinion. This is true for a number of myths which continue to haunt the literature with respect to feigned health problems. Such myths tend to ignore or to distort the results of modern research. We performed two pilot studies: first a content analysis of 67 German- and English-language articles from newspapers, magazines or internet journals, and second, a survey on the experience of, and beliefs related to, exaggeration and symptom invention in health care and forensic assessment. A non-representative sample of 15 adults from the general population was interviewed. Most of them reported their own experiences or incidents in their social networks involving feigned health problems. Base rate estimates of malingering in five prototypical contexts ranged between 46 and 67 percent of cases. While the participants showed a preference for an adaptational explanatory model of malingering (selected for about 53% of cases of malingering), journalistic sources often employed pejorative language and combat rhetoric, aiming to arouse indignation or outrage in the readership. The majority of articles were classified to adhere to a criminological explanatory model. While the pilot character of the studies limits their generalisability, the results may be suited to question the validity of some long-held expert beliefs.

  10. Conventional vs unconventional assisted reproductive technologies: opinions of young physicians.

    In the last three and a half decades, an increasing number of assisted reproductive technologies (ARTs) have been developed, some of them already being used in clinical practice, while others will probably remain purely theoretical due to their associated ethical issues. The purpose of this study was to analyse the opinions of medical residents regarding various ARTs, both classical and unconventional. We conducted a multi-institutional survey among 142 medical residents in order to assess the views of young physicians of regarding ARTs. Most responders were in favour of medical procedures like gamete donation and surrogacy. When asked about more controversial procedures such as posthumous sperm procurement or reproductive cloning, most were against. Progress in reproductive medicine is made at a fast pace, as more and more couples are found infertile and as the birth rate in developed countries becomes smaller and smaller. If not carefully followed and regulated, this can easily lead to the development of highly controversial procedures, which can significantly alter the way we see human reproduction. As the law has a very traditional approach, it is often left behind by progress in this field, leaving potentially controversial procedures unregulated for long periods of time. During these periods, physicians have the very important role of analysing what is good and what is not and when to recognise procedures that go against general ethical and medical principles.

A two-level random-effects regression model assessed the influence of Organizational Readiness for Change (ORC) and organizational attributes on opinions toward the use of four evidence-based practices (manualized treatments, medication, integrated mental health services, and motivational incentives) and practices with less empirical support (confrontation and noncompliance discharge). The ORC scales suggested greater support for evidence-based practices in programs where staff perceived more program need for improvement, better Internet access, higher levels of peer influence, more opportunities for professional growth, a stronger sense of organizational mission, and more organizational stress. Support for confrontation and noncompliance discharge, in contrast, was strong when staff saw less opportunity for professional growth, weaker peer influence, less Internet access, and perceived less organizational stress. The analysis provides evidence of the ORC's utility in assessing agency strengths and needs during the implementation of evidence-based practices.

  12. What prostate cancer patients should know: variation in professionals' opinions

    International Nuclear Information System (INIS)

    Purpose: This study was designed to determine what questions health-care professionals think should be addressed with curable prostate cancer patients before treatment decisions are made. Method: A survey was distributed to radiation oncologists, urologists, medical oncologists, nurses and radiation therapy technologists (RTTs) involved in treating prostate cancer patients. Participants were asked to judge the importance of addressing each of 78 questions (essential/important/no opinion/avoid) with a described hypothetical patient prior to the treatment decision. Eighty participants were later selected at random for a retest. Results: The overall response rate was 55% (284/518) on the initial survey and 56% (45/80) on the retest. The relative importance of the various questions was similar across groups (r(76) ranged from 0.75 to 0.91, all P<0.00190% respondent agreement on only 15 of the 78 questions. The extent of agreement was similar in the other groups. The retest showed that essential and important responses were reasonably stable, i.e. 92% of questions judged essential at one time were judged either essential (58%) or important (34%) at the other time. Conclusions: Although the relative importance of addressing the various questions appears similar across the professional groups involved in the care of prostate patients, within each profession there seems to be little agreement. The lack of agreement includes both how many questions are essential to address and whether or not most individual questions are essential. (Copyright (c) 1998 Elsevier Science B.V., Amsterdam.

    Full Text Available Objective: To examine the opinions of Libyan doctors regarding the quality of drug information provided by pharmaceutical company representatives (PCRs during detailing visits. Method: An anonymous survey was conducted among 1,000 doctors from selected institutes in Tripoli, Benghazi and Sebha. Doctors were asked questions regarding the quality of information provided during drug-detailing visits. Results: A questionnaire return rate of 61% (608 returned questionnaires out of 1,000 was achieved. The majority (n=463, 76% of surveyed participants graded the quality of information provided as average. Approximately, 40% of respondents indicated that contraindications, precautions, interactions and adverse effects of products promoted by PCRs were never or rarely mentioned during promotional visits, and 65% of respondents indicated that an alternative drug to the promoted product was never or rarely mentioned by the representatives. More than 50% of respondents (n=310, 51% reported that PCRs were not always able to answer all questions about their products. Only seven respondents (1% believed that PCRs never exaggerated the uniqueness, efficacy or safety of their product. The majority of respondents (n=342, 56% indicated that verbal information was not always consistent with written information provided. Seven per cent of respondents (n=43 admitted that they did not know whether or not the verbal information provided by PCRs was consistent with written information. Conclusion: Doctors believe that the provision of drug information by PCRs in Libya is incomplete and often exaggerated. Pharmaceutical companies should ensure that their representatives are trained to a standard to provide reliable information regarding the products they promote.

    2007-09-01

    This study was conducted to gain opinions about euthanasia from nurses who work in intensive care units. The research was planned as a descriptive study and conducted with 186 nurses who worked in intensive care units in a university hospital, a public hospital, and a private not-for-profit hospital in Adana, Turkey, and who agreed to complete a questionnaire. Euthanasia is not legal in Turkey. One third (33.9%) of the nurses supported the legalization of euthanasia, whereas 39.8% did not. In some specific circumstances, 44.1% of the nurses thought that euthanasia was being practiced in our country. The most significant finding was that these Turkish intensive care unit nurses did not overwhelmingly support the legalization of euthanasia. Those who did support it were inclined to agree with passive rather than active euthanasia (P = 0.011).

    Humans, like many other animal species, often make choices under social influence. Experiments in ants and fishes have shown that individuals choose according to estimations of which option to take given private and social information. Principled approaches based on probabilistic estimations by agents give mathematical formulas explaining experiments in these species. Here we test whether the same principled approaches can explain social influence in humans. We conduct a large online field experiment in which we measure opinion influenced by public comments about short movies in the most popular video-sharing website. We show that the basic principles of social influence in other species also apply to humans, with the added complexity that humans are heterogenous. We infer influenceability of each participant of the experiment, finding that individuals prone to social influence tend to agree with social feedback, read less comments, and are less educated than the persons who resist influence. We believe that ...

  19. Deciphering cis-regulatory control in inflammatory cells.

    Ghisletti, Serena; Natoli, Gioacchino

    2013-01-01

    In innate immune system cells, such as macrophages and dendritic cells, deployment of inducible gene expression programmes in response to microbes and danger signals requires highly precise regulatory mechanisms. The inflammatory response has to be tailored based on both the triggering stimulus and its dose, and it has to be unfolded in a kinetically complex manner that suits the different phases of the inflammatory process. Genomic characterization of regulatory elements in this context indicated that transcriptional regulators involved in macrophage specification act as pioneer transcription factors (TFs) that generate regions of open chromatin that enable the recruitment of TFs activated in response to external inputs. Therefore, competence for responses to a specific stimulus is programmed at an early stage of differentiation by factors involved in lineage commitment and maintenance of cell identity, which are responsible for the organization of a cell-type-specific cis-regulatory repertoire. The basic functional and organizational principles that regulate inflammatory gene expression in professional cells of the innate immune system provide general paradigms on the interplay between differentiation and environmental responses.

  20. Changes in Cis-regulatory Elements during Morphological Evolution

    Directory of Open Access Journals (Sweden)

    Yu-Lee Paul

    2012-10-01

    Full Text Available How have animals evolved new body designs (morphological evolution? This requires explanations both for simple morphological changes, such as differences in pigmentation and hair patterns between different Drosophila populations and species, and also for more complex changes, such as differences in the forelimbs of mice and bats, and the necks of amphibians and reptiles. The genetic changes and pathways involved in these evolutionary steps require identification. Many, though not all, of these events occur by changes in cis-regulatory (enhancer elements within developmental genes. Enhancers are modular, each affecting expression in only one or a few tissues. Therefore it is possible to add, remove or alter an enhancer without producing changes in multiple tissues, and thereby avoid widespread (pleiotropic deleterious effects. Ideally, for a given step in morphological evolution it is necessary to identify (i the change in phenotype, (ii the changes in gene expression, (iii the DNA region, enhancer or otherwise, affected, (iv the mutation involved, (v the nature of the transcription or other factors that bind to this site. In practice these data are incomplete for most of the published studies upon morphological evolution. Here, the investigations are categorized according to how far these analyses have proceeded.

    Research highlights: {yields} The extremely slow trans-OPPS reaction using 2-Fluoro-FPP supports the sequential mechanism with the carbocation intermediate. {yields} The similar UPPS reaction rate under single turnover supports the concerted mechanism, without the carbocation intermediate. {yields} The secondary kinetic isotope effect also supports associate transition state for UPPS reaction, without the carbocation intermediate. -- Abstract: Undecaprenyl pyrophosphate synthase (UPPS) is a cis-type prenyltransferases which catalyzes condensation reactions of farnesyl diphosphate (FPP) with eight isopentenyl pyrophosphate (IPP) units to generate C{sub 55} product. In this study, we used two analogues of FPP, 2-fluoro-FPP and [1,1-{sup 2}H{sub 2}]FPP, to probe the reaction mechanism of Escherichia coli UPPS. The reaction rate of 2-fluoro-FPP with IPP under single-turnover condition is similar to that of FPP, consistent with the mechanism without forming a farnesyl carbocation intermediate. Moreover, the deuterium secondary KIE of 0.985 {+-} 0.022 measured for UPPS reaction using [1,1-{sup 2}H{sub 2}]FPP supports the associative transition state. Unlike the sequential mechanism used by trans-prenyltransferases, our data demonstrate E. coli UPPS utilizes the concerted mechanism.

    2005-10-01

    Full Text Available Abstract Background Cis-regulatory modules (CRMs are short stretches of DNA that help regulate gene expression in higher eukaryotes. They have been found up to 1 megabase away from the genes they regulate and can be located upstream, downstream, and even within their target genes. Due to the difficulty of finding CRMs using biological and computational techniques, even well-studied regulatory systems may contain CRMs that have not yet been discovered. Results We present a simple, efficient method (HexDiff based only on hexamer frequencies of known CRMs and non-CRM sequence to predict novel CRMs in regulatory systems. On a data set of 16 gap and pair-rule genes containing 52 known CRMs, predictions made by HexDiff had a higher correlation with the known CRMs than several existing CRM prediction algorithms: Ahab, Cluster Buster, MSCAN, MCAST, and LWF. After combining the results of the different algorithms, 10 putative CRMs were identified and are strong candidates for future study. The hexamers used by HexDiff to distinguish between CRMs and non-CRM sequence were also analyzed and were shown to be enriched in regulatory elements. Conclusion HexDiff provides an efficient and effective means for finding new CRMs based on known CRMs, rather than known binding sites.

    cis,cis-Muconic acid is a polyunsaturated dicarboxylic acid that can be produced renewably via the biological conversion of sugars and lignin-derived aromatic compounds. Subsequently, muconic acid can be catalytically converted to adipic acid -- the most commercially significant dicarboxylic acid manufactured from petroleum. Nylon-6,6 is the major industrial application for adipic acid, consuming 85% of market demand; however, high purity adipic acid (99.8%) is required for polymer synthesis. As such, process technologies are needed to effectively separate and catalytically transform biologically derived muconic acid to adipic acid in high purity over stable catalytic materials. To that end, this study: (1) demonstrates bioreactor production of muconate at 34.5 g L-1 in an engineered strain of Pseudomonas putida KT2440, (2) examines the staged recovery of muconic acid from culture media, (3) screens platinum group metals (e.g., Pd, Pt, Rh, Ru) for activity and leaching stability on activated carbon (AC) and silica supports, (4) evaluates the time-on-stream performance of Rh/AC in a trickle bed reactor, and (5) demonstrates the polymerization of bio-adipic acid to nylon-6,6. Separation experiments confirmed AC effectively removed broth color compounds, but subsequent pH/temperature shift crystallization resulted in significant levels of Na, P, K, S and N in the crystallized product. Ethanol dissolution of muconic acid precipitated bulk salts, achieving a purity of 99.8%. Batch catalysis screening reactions determined that Rh and Pd were both highly active compared to Pt and Ru, but Pd leached significantly (1-9%) from both AC and silica supports. Testing of Rh/AC in a continuous trickle bed reactor for 100 h confirmed stable performance after 24 h, although organic adsorption resulted in reduced steady-state activity. Lastly, polymerization of bio-adipic acid with hexamethyldiamine produced nylon-6,6 with comparable properties to its petrochemical counterpart

  5. Influence of opinion dynamics on the evolution of games.

    Directory of Open Access Journals (Sweden)

    Floriana Gargiulo

    Full Text Available Under certain circumstances such as lack of information or bounded rationality, human players can take decisions on which strategy to choose in a game on the basis of simple opinions. These opinions can be modified after each round by observing own or others payoff results but can be also modified after interchanging impressions with other players. In this way, the update of the strategies can become a question that goes beyond simple evolutionary rules based on fitness and become a social issue. In this work, we explore this scenario by coupling a game with an opinion dynamics model. The opinion is represented by a continuous variable that corresponds to the certainty of the agents respect to which strategy is best. The opinions transform into actions by making the selection of an strategy a stochastic event with a probability regulated by the opinion. A certain regard for the previous round payoff is included but the main update rules of the opinion are given by a model inspired in social interchanges. We find that the fixed points of the dynamics of the coupled model are different from those of the evolutionary game or the opinion models alone. Furthermore, new features emerge such as the independence of the fraction of cooperators with respect to the topology of the social interaction network or the presence of a small fraction of extremist players.

  17. Discrete opinion dynamics on networks based on social influence

    International Nuclear Information System (INIS)

    A model of opinion dynamics based on social influence on networks was studied. The opinion of each agent can have integer values i = 1, 2, ..., I and opinion exchanges are restricted to connected agents. It was found that for any I ≥ 2 and self-confidence parameter 0 ≤ u i) of the population that hold a given opinion i is a martingale, and the fraction qi of opinion i will gradually converge to (qi). The tendency can slow down with the increase of degree assortativity of networks. When u is degree dependent, (qi) does not possess the martingale property, however qi still converges to it. In both cases for a finite network the states of all agents will finally reach consensus. Further if there exist stubborn persons in the population whose opinions do not change over time, it was found that for degree-independent constant u, both qi and (qi) will converge to fixed proportions which only depend on the distribution of initial obstinate persons, and naturally the final equilibrium state will be the coexistence of diverse opinions held by the stubborn people. The analytical results were verified by numerical simulations on Barabasi-Albert (BA) networks. The model highlights the influence of high-degree agents on the final consensus or coexistence state and captures some realistic features of the diffusion of opinions in social networks

  1. Thermal processing differentially affects lycopene and other carotenoids in cis-lycopene containing, tangerine tomatoes.

    Cooperstone, Jessica L; Francis, David M; Schwartz, Steven J

    2016-11-01

    Tangerine tomatoes, unlike red tomatoes, accumulate cis-lycopenes instead of the all-trans isomer. cis-Lycopene is the predominating isomeric form of lycopene found in blood and tissues. Our objective was to understand how thermal processing and lipid concentration affect carotenoid isomerisation and degradation in tangerine tomatoes. We conducted duplicated factorial designed experiments producing tangerine tomato juice and sauce, varying both processing time and lipid concentration. Carotenoids were extracted and analysed using high-performance liquid chromatography with photodiode array detection. Phytoene, phytofluene, ζ-carotene, neurosporene, tetra-cis-lycopene, all-trans-lycopene and other-cis-lycopenes were quantified. Tetra-cis-lycopene decreased with increasing heating time and reached 80% of the original level in sauce after processing times of 180min. All-trans-lycopene and other-cis-lycopenes increased with longer processing times. Total carotenoids and total lycopene decreased with increased heating times while phytoene and phytofluene were unchanged. These data suggest limiting thermal processing of tangerine tomato products if delivery of tetra-cis-lycopene is desirable. PMID:27211672

  2. Favorable genomic environments for cis-regulatory evolution: A novel theoretical framework.

    2016-09-01

    Cis-regulatory changes are arguably the primary evolutionary source of animal morphological diversity. With the recent explosion of genome-wide comparisons of the cis-regulatory content in different animal species is now possible to infer general principles underlying enhancer evolution. However, these studies have also revealed numerous discrepancies and paradoxes, suggesting that the mechanistic causes and modes of cis-regulatory evolution are still not well understood and are probably much more complex than generally appreciated. Here, we argue that the mutational mechanisms and genomic regions generating new regulatory activities must comply with the constraints imposed by the molecular properties of cis-regulatory elements (CREs) and the organizational features of long-range chromatin interactions. Accordingly, we propose a new integrative evolutionary framework for cis-regulatory evolution based on two major premises for the origin of novel enhancer activity: (i) an accessible chromatin environment and (ii) compatibility with the 3D structure and interactions of pre-existing CREs. Mechanisms and DNA sequences not fulfilling these premises, will be less likely to have a measurable impact on gene expression and as such, will have a minor contribution to the evolution of gene regulation. Finally, we discuss current comparative cis-regulatory data under the light of this new evolutionary model, and propose that the two most prominent mechanisms for the evolution of cis-regulatory changes are the overprinting of ancestral CREs and the exaptation of transposable elements.

    Full Text Available Abstract Background Cigarette taxation has been perceived by academics and policy-makers as one of the most effective ways of reducing the use of cigarettes. On January 1 2002, the Taiwan government imposed a New Taiwan (NT $5 per pack tax earmarked for the purpose of tobacco control. This study uses a survey collected prior to taxation to assess public attitudes toward cigarette taxation, public beliefs about the effectiveness of cigarette taxation at reducing cigarette use and public opinions about the allocation of this tax revenue. Methods Data were drawn from a national face-to-face interview on cigarette consumption in 2000. A total of 3,279 adults were aged 18 to 64 years; 49.9% of whom were male and 50.1% female, and with a smoking prevalence of 49.1% and 4.1%, respectively. The attitudes toward cigarette tax were analysed using multi-logit regressions. We analysed by logistic regression the potential changes in smoking behaviour that smokers might make in response to the five NT (New Taiwan dollar earmarked tax on cigarettes per pack. We summarized public opinions about the allocation of earmarked tax revenue using descriptive statistics. Results Current smokers (OR = 0.34 and former smokers (OR = 0.68 were less likely to support the cigarette tax than non-smokers. A favourable attitude toward the tax was positively associated with personal monthly income, especially among females. Among male smokers, the possibility of reducing/quitting smoking in response to the five-NT-dollar tax was negatively associated with the monthly expense for smoking. The two most frequently-suggested areas to receive money from the revenue collected from the earmarked tax were health education and cancer subsidy. Conclusions Smoking status and economic factors determine the attitude and potential responses of people toward the cigarette tax. Taiwan's five NT-dollar earmarked tax for cigarettes may have only a limited effect upon the reduction in cigarette

    Two rapidly growing propionibacteria that could reductively dechlorinate tetrachloroethylene (PCE) and cis-1,2-dichloroethylene (cis-DCE) to ethylene were isolated from environmental sediments. Metabolic characterization and partial sequence analysis of their 16S rRNA genes showed that the new isolates, designated as strains Propionibacterium sp. HK-1 and Propionibacterium sp. HK-3, did not match any known PCE- or cis-DCE-degrading bacteria. Both strains dechlorinated relatively high concentrations of PCE (0.3 mM) and cis-DCE (0.52 mM) under anaerobic conditions without accumulating toxic intermediates during incubation. Cell-free extracts of both strains catalyzed PCE and cis-DCE dechlorination; degradation was accelerated by the addition of various electron donors. PCE dehalogenase from strain HK-1 was mediated by a corrinoid protein, since the dehalogenase was inactivated by propyl iodide only after reduction by titanium citrate. The amounts of chloride ions (0.094 and 0.103 mM) released after PCE (0.026 mM) and cis-DCE (0.05 mM) dehalogenation using the cell-free enzyme extracts of both strains, HK-1 and HK-3, were stoichiometrically similar (91 and 100%), indicating that PCE and cis-DCE were fully dechlorinated. Radiotracer studies with [1,2-¹⁴C] PCE and [1,2-¹⁴C] cis-DCE indicated that ethylene was the terminal product; partial conversion to ethylene was observed. Various chlorinated aliphatic compounds (PCE, trichloroethylene, cis-DCE, trans-1,2-dichloroethylene, 1,1-dichloroethylene, 1,1-dichloroethane, 1,2-dichloroethane, 1,2-dichloropropane, 1,1,2-trichloroethane, and vinyl chloride) were degraded by cell-free extracts of strain HK-1.

    While the number and variety of models to explain opinion exchange dynamics is huge, attempts to justify the model results using empirical data are relatively rare. As linking to real data is essential for establishing model credibility, this Letter develops an empirical confirmation experiment by which an opinion model is related to real election data. The model is based on a representation of opinions as a vector of k bits. Individuals interact according to the principle that similarity leads to interaction and interaction leads to still more similarity. In the comparison to real data we concentrate on the transient opinion profiles that form during the dynamic process. An artificial election procedure is introduced which allows to relate transient opinion configurations to the electoral performance of candidates for which data are available. The election procedure based on the well-established principle of proximity voting is repeatedly performed during the transient period and remarkable statistical agreement with the empirical data is observed.

    Social influence is the process by which individuals adapt their opinion, revise their beliefs, or change their behavior as a result of social interactions with other people. In our strongly interconnected society, social influence plays a prominent role in many self-organized phenomena such as herding in cultural markets, the spread of ideas and innovations, and the amplification of fears during epidemics. Yet, the mechanisms of opinion formation remain poorly understood, and existing physics-based models lack systematic empirical validation. Here, we report two controlled experiments showing how participants answering factual questions revise their initial judgments after being exposed to the opinion and confidence level of others. Based on the observation of 59 experimental subjects exposed to peer-opinion for 15 different items, we draw an influence map that describes the strength of peer influence during interactions. A simple process model derived from our observations demonstrates how opinions in a gro...

  8. Ranking System for Opinion Mining of Features from Review Documents

    2012-07-01

    Full Text Available With the exponential growth of the web there has been explosive increase in the user generated contents in the form of customer reviews, blogs, discussion forums, social networks etc. Most of the contents are stored in the form of unstructured or semi structured data from where distillation of knowledge is a challenging task. In this paper we propose a feature wise opinion mining system which first extracts features from user generated contents, then determines the intensity of the opinions by giving emphasis to the modifier of the words, which expresses opinions. It finds the numeric score of all the features using Senti-WordNet and then calculates the overall orientation of the feature to determine how intense the opinion is for both the positive and negative features. The positive and negative features are identified by extracting the associated modifiers and opinions. The summary is presented by specifying the features in descending order of importance.

    We investigate the role of opinion leaders or influentials in the collective behavior of a social system. Opinion leaders are characterized by their unidirectional influence on other agents. We employ a model based in Axelrod's dynamics for cultural interaction among social agents that allows for non-interacting states. We find three collective phases in the space of parameters of the system, given by the fraction of opinion leaders and a quantity representing the number of available states: one ordered phase having the state imposed by the leaders; another nontrivial ordered phase consisting of a majority group in a state orthogonal or alternative to that of the opinion leaders, and a disordered phase, where many small groups coexist. We show that the spontaneous rise of an alternative group in the presence of opinion leaders depends on the existence of a minimum number of long-range connections in the underlying network. This phenomenon challenges the common idea that influentials are important to spreading...

  11. Public opinion about biofuels: The interplay between party identification and risk/benefit perception

    International Nuclear Information System (INIS)

    Using an experiment embedded within a representative survey, this study examined the interactive effect of party identification and risk/benefit perception on public opinion about biofuels. Democrats tended to be more supportive of biofuels than Republicans. However, the effect of party identification on opinion about biofuels varied when individuals considered the risk/benefit of biofuels in different domains. Individuals who reported greater affiliation with the Democratic Party were likely to support funding biofuels research when primed with the economic risks or the social/ethical benefits of biofuels. For those who considered the social/ethical benefits of biofuels, more self-identified Democrats were likely to support biofuels production and use. However, more self-identified Democrats were less supportive of biofuels production and use when they considered the political risks of biofuels. Implications are discussed. - Highlights: • We examined public opinion about biofuels policies. • Effect of risk/benefit perception varied across respondents' party identification. • Democrats favored more research when considering economic risks or social benefits. • Democrats favored biofuels more when considering social benefits. • Democrats favored biofuels less when considering political risks

  12. The EU Economic Crisis – Reflections in the Opinions of Citizens and Experts

    Full Text Available Perhaps one of the most important challenges that the EU is currently facing is that of building public support for the Union project as the economic crisis develops, confidence in the EU future is weakened and member states turn to their own boundaries. Therefore, this research aims at identifying the public opinion on the economic future of the European Union in the particular context of the euro crisis, given the fact that utilitarian considerations represent a key driver for the Europeanization process. At the same time, we compare expert opinions about the impact of the crisis on the future of the European Union, as well as the perceptions of ordinary people. To accomplish the research goals, we conducted expert interviews with 11 of the most prominent economic experts in Romania and a national survey (N=1002. The study supports the perspective that citizens’ opinions about the economic evolution of the European Union are largely based on their sociotropic and egocentric economic assessments. The crisis influences the perspectives on the EU, but only by tempering optimism, turning it into a moderate view. This result can be extended to other Central-Eastern states as well, due to their resembling paths. Also, experts indicate various scenarios when referring to the impact of the crisis on the EU’s future, but beyond the variations, the prospects are neither optimistic, nor pessimistic, but rather moderate.

    Lawyers are important actors shaping the abortion debate in Mexico. Of 250 private and public sector criminal lawyers surveyed from four regions, the majority knew about abortion laws in their states. At least 80% agreed with abortion in cases of rape, risk to a woman's life or health, and fetal malformations. Overall, 61% agreed with the Mexico City law and 84% would defend a woman denied a legal abortion. In multivariate analysis, being very knowledgeable of abortion laws was a significant predictor of more "progressive" abortion opinions, support for the Mexico City law, and support for the health indication.

    We assessed public opinion on nutrition-related policies to address child obesity: a soda tax, restrictions on advertising unhealthy foods and beverages to children, and restrictions on siting fast food restaurants and convenience stores near schools. We analyzed data from 998 adults (aged ≥18 years) in the 2011 Los Angeles County Health Survey. Support was highest for advertising restrictions (74%), intermediate for a soda tax (60%), and lowest for siting restrictions on fast food restaurants and convenience stores (44% and 37%, respectively). Support for food and beverage advertising restrictions and soda taxation is promising for future policy efforts to address child obesity.

    As of 2012, the EU has banned the use of conventional cages (CC) for laying hens, causing a shift in housing systems. This study’s aim was to gain insight into farmers’ opinions on hen health and welfare in their current housing systems. A survey was sent to 218 Belgian egg farmers, of which 127 (58.3%) responded, with 84 still active as egg farmer. Hen welfare tended to be less important in choosing the housing system for farmers with cage than with non-cage systems. Respondents currently us...

    The objective of this survey was to obtain user feedback to, among other things, determine how to organize the exponentially growing data within the Atmospheric Radiation Measurement (ARM) Climate Research Facility, and identify users’ preferred data analysis system. The survey findings appear to have met this objective, having received approximately 300 responses that give insight into the type of work users perform, usage of the data, percentage of data analysis users might perform on an ARM-hosted computing resource, downloading volume level where users begin having reservations, opinion about usage if given more powerful computing resources (including ability to manipulate data), types of tools that would be most beneficial to them, preferred programming language and data analysis system, level of importance for certain types of capabilities, and finally, level of interest in participating in a code-sharing community.

  20. Quasiperiodic orbit analysis of nonadiabatic cis-trans photoisomerization dynamics

    2003-08-01

    Adopting a multidimensional model of nonadiabatic cis-trans photoisomerization, quantum-mechanical and classical simulations of the ultrafast wave-packet dynamics associated with this photoreaction are presented. The quantum calculations demonstrate that nonadiabatic photoisomerization typically leads to a largely delocalized and diffuse wave function, which hampers an intuitive understanding of the dynamics in terms of specific nuclear motion. To facilitate a classical description, a recently proposed theoretical formulation is employed that affords an exact mapping of discrete electronic states onto continuous degrees of freedom and therefore provides a well-defined classical limit of a nonadiabatically coupled system. It is shown that a simple quasiclassical implementation of the mapping formulation is able to reproduce at least qualitatively the complex quantum dynamics of the system. In addition, the classical description allows us to characterize the nonadiabatic photoisomerization dynamics in terms of a few "quasiperiodic orbits." These orbits are close to a true unstable periodic orbit but are exactly periodic only with respect to the slow reaction coordinate of the system. Various types of quasiperiodic orbits of nonadiabatic photoisomerization are identified and analyzed. It is shown that the diffuse appearance of the quantum-mechanical wave function can be directly connected to irregular classical orbits propagating on vibronically coupled potential-energy surfaces. The chaotic behavior of the system is mainly caused by the relatively high energy corresponding to photoexcitation, the large anharmonicity of the isomerization potentials, and the reflection of the trajectory at surface crossings. The results demonstrate that quasiperiodic orbits represent a concept well suited to analyze the quantum dynamics of complex systems in terms of classical trajectories without the cumbersome search for periodic orbits.
