    Managing the ageing of fuel cycle facilities (FCFs) means, as for other nuclear installations, ensuring the availability of required safety functions throughout their service life while taking into account the changes that occur with time and use. This technical opinion paper identifies a set of good practices by benchmarking strategies and good practices on coping with physical ageing and obsolescence from the facility design stage until decommissioning. It should be of particular interest to nuclear safety regulators, fuel cycle facilities operators and fuel cycle researchers [fr

  2. CSNI Technical Opinion Papers No. 14 - Nuclear Licensee Organisational Structures, Resources and Competencies: Determining their Suitability

    International Nuclear Information System (INIS)

    2012-01-01

    The way in which nuclear licensees' organisations are structured and resourced clearly has a potential impact on nuclear safety. As experience has continually demonstrated, operating organisations with a strong training programme for personnel, adequate resourcing and overall effective leadership and management perform more effectively in times of crisis than those lacking in one or more of these areas. In parallel, the nuclear industry is developing new resource deployment strategies which are making increased use of contractors and leading to changes in organisational structure, which in turn create challenges for the continued safe operation of nuclear facilities. This technical opinion paper represents the consensus among human and organisational factor specialists in NEA member and associated countries on the methods, approaches and good practices to be followed in designing an organisation with a strong safety focus while meeting business needs. It also considers some of the attributes that an organisation which is effectively managing its resources and capabilities might demonstrate

  3. CSNI Technical Opinion Papers No. 16 - Defence in Depth of Electrical Systems

    International Nuclear Information System (INIS)

    2013-01-01

    As all safety systems in the majority of existing nuclear power plants use the preferred power supply, any voltage surges in these systems could lead to common-cause failures. In the event of an unusual electrical system transient, it is essential that safety-related equipment be isolated or protected from the fault in order to ensure its ability to safely shut down the reactor and remove decay heat. Based on the analysis of the voltage surges observed at Forsmark-1 in 2006 and Olkiluoto-1 in 2008, this technical opinion paper summarises the current state of knowledge of in-plant and external grid-related challenges to nuclear power plant safety-related electrical equipment. It will be of particular interest to nuclear safety regulators, nuclear power plant operators and grid system regulators and operators

  4. CSNI technical opinion papers no.5. Managing and regulating organisational change in nuclear installations

    International Nuclear Information System (INIS)

    2004-01-01

    Nuclear licensees are increasingly required to adapt to a more challenging commercial environment as electricity markets are liberalized. One of the costs that is often perceived as being amenable to control is staffing, and hence there is significant exploration of new strategies for managing this cost - for example, by reducing staffing levels, changing organisational structures, adopting new shift strategies, introducing new technology or increasing the proportion of work carried out by external contractors. However, if changes to staffing levels or organisational structures and systems are inadequately conceived or executed they have the potential to affect the way in which safety is managed. In this context, the NEA Committee on the Safety of Nuclear Installations (CSNI) and its Special Expert Group on Human and Organisational Factors (SEGHOF) organised an international workshop to discuss the management and regulation of organisational change in 2001. This technical opinion paper distills the findings of that workshop and sets out the factors that regulatory bodies might reasonably expect to be addressed within licensees arrangements to manage organisational change. The paper should be of particular interest to both regulators and managers of nuclear utilities. (author)

  5. CSNI technical opinion papers no.10. The role of human and organisational factors in nuclear power plant modifications

    International Nuclear Information System (INIS)

    2009-01-01

    Nuclear power plant modifications may be needed for a number of different reasons. These include physical ageing of plant systems, structures and components; obsolescence in hardware and software; feedback from operating experience; and opportunities for improved plant safety, reliability or capability. However, experience has also shown that weaknesses in the design and/or implementation of modifications can present significant challenges to plant safety. They can also have a considerable impact on the commercial performance of the plant. It is therefore important that the plant modification process reflect a recognition of the potential impact of human errors and that it incorporate suitable measures to minimise the potential for such errors. In this context, the NEA Committee on the Safety of Nuclear Installations (CSNI) and its Working Group on Human and Organisational Factors organised an international workshop in 2003 to discuss the role of human and organisational performance in the nuclear plant modification process. This technical opinion paper represents the consensus of specialists in human and organisational factors (HOF) in the NEA member countries on commendable practices and approaches to dealing with nuclear plant modifications. It considers factors that should be taken into account when developing a modification process and identifies some lessons learnt from application of the process. The paper should be of particular interest of nuclear safety regulators and nuclear power plant operators. (author)

  8. The need for contextualized scientometric analysis: An opinion paper

    Energy Technology Data Exchange (ETDEWEB)

    Waltman, L.; Van Eck, N.J.

    2016-07-01

    Scientometric indicators, in particular indicators based on citations, nowadays play a prominent role in research evaluations. Given the importance of these indicators, scientometricians are putting a lot of effort into making technical improvements to the indicators in order to increase their accuracy. Especially indicators based on citations have received a lot of attention during recent years. This has resulted in the development of many advanced citation-based indicators (for a review of the literature, see Waltman, 2016). At the same time, scientometricians have been exploring all kinds of new indicators, many of which are referred to as altmetric indicators. Interest in these new indicators is largely driven by the availability of new data sources, but also seems to relate to changing viewpoints on research evaluation, in particular an increasing focus on evaluating the societal impact of research. Like in the case of traditional citation-based indicators, scientometricians are trying to obtain more and more accurate statistics by developing increasingly advanced indicators (e.g., Fairclough & Thelwall, 2015; Haunschild & Bornmann, 2016).

  8. Final waste classification and waste form technical position papers

    International Nuclear Information System (INIS)

    1983-05-01

    The waste classification technical position paper describes overall procedures acceptable to NRC staff which may be used by licensees to determine the presence and concentrations of the radionuclides listed in section 61.55, and thereby classifying waste for near-surface disposal. This technical position paper also provides guidance on the types of information which should be included in shipment manifests accompanying waste shipments to near-surface disposal facilities. The technical position paper on waste form provides guidance to waste generators on test methods and results acceptable to NRC staff for implementing the 10 CFR Part 61 waste form requirements. It can be used as an acceptable approach for demonstrating compliance with the 10 CFR Part 61 waste structural stability criteria. This technical position paper includes guidance on processing waste into an acceptable stable form, designing acceptable high-integrity containers, packaging cartridge filters, and minimizing radiation effects on organic ion-exchange resins. The guidance in the waste form technical position paper may be used by licensees as the basis for qualifying process control programs to meet the waste form stability requirements, including tests which can be used to demonstrate resistance to degradation arising from the effects of compression, moisture, microbial activity, radiation, and chemical changes. Generic test data (e.g., topical reports prepared by vendors who market solidification technology) may be used for process control program qualification where such generic data is applicable to the particular types of waste generated by a licensee

  9. Career and technical education system: Estimates and opinions of the graduates

    Directory of Open Access Journals (Sweden)

    A T Gasparishvili

    2016-12-01

    Full Text Available The article is based on the results of the project “Education, labor market and social behavior of the youth under the current economic situation”, in which the sociological study of the professional orientations and plans of the Russian career and technical schools graduates was conducted. The graduates explained their reasons for the career choice, and what factors influenced such a decision, discussed their plans after graduation, expressed their opinions on the quality of education and the educational level necessary to be successful in life. According to the research data, the graduates aim to pursue a higher education degree to become more competitive in the labor market. For most of them, the career and technical education system is an intermediate, “secondary” step in the planned life trajectory. The research data also show significant differences in the motives of certain groups, for instance, students of medical and pedagogical colleges are more committed to the moral values of serving the society than those who plan to work in the commercial sector, service sector, etc. Thus, the data of the study is useful for planning and changing the state and departmental policies in both career and technical education and higher education.

  10. Opinion Paper: A Cognitive-cultural Segregation and the Three Stages of Aging.

    Science.gov (United States)

    Kyriazis, Marios

    2016-01-01

    There is no doubt that the world is divided and unequal, mostly with respect to wealth. However, the true obstacle preventing the progress of humanity is not the divide between the rich and the poor. It is the divide between the cognitive and the physical. Apart from the social and ethical issues associated with this, there are also medical ones. The implications of this divide have direct relevance to aging, both in research and in the clinical sense. We cannot simply apply the same 'healthy aging' guidelines to everybody, but we need to establish if our approach is specifically suited to the individual. Our research endeavours need to have this division in focus. In this Opinion paper I describe three separate groups of humanity, which are divided, not by economic criteria, but by a worldview of intellectual creativity. Each arbitrary group has its own health priorities. If we overlook these priorities we may, at best, give the wrong advice to our patients, or at worst waste resources and exacerbate the rate of age-related degeneration in many individuals. As our society becomes more reliant on technology, what is now considered 'healthy' may not be so, for many millions of people.

  11. Opinion paper: scientific, philosophical and legal consideration of doping in sports.

    2018-04-01

    The term doping is generally used to indicate practices based on the use of performance-enhancing drugs (PEDs) or the abuse of medical therapies. Mostly analysed by doctors and officials, doping nevertheless also requires a philosophical consideration to avoid being simplistically portrayed as an isolated practice. To do this, we need to pay attention to the contradictions and paradoxes in the modern approach to doping in sport. In this context, doping is not only relevant to the health of an individual involved in the violation of World Anti-Doping Agency (WADA) criteria, but it actually represents a double-edged phenomenon containing ethical and legal points of view. Several philosophical items affect the ethics of doping. While, indeed, through a deontological vision it is easy to morally condemn an athlete who takes the decision to turn to doping, the same condemnation becomes difficult when the practice of doping is compared with the strong social demand of winners in every field of life. This point must be considered to prevent doping from becoming accepted as a daily practice to excel at all costs and regarded not only as normal but as a necessity for those participating in sport at both an amateur and professional level. Furthermore, a complete discussion on doping has to consider not only the philosophy of performance-enhancing drug abuse, but also the widespread practice of an inappropriate and excessive intake of certain dietary supplements with the unique and obsessive purpose (similar to doping) of increasing physical or mental performance. Based on the above, the aim of this paper is to provide a critical opinion of the doping problem and its related practices and analyze possible solutions considering issues that go beyond the impact of doping on health and reflect on whether it is right or not that an athlete does all he can to improve his performance.

  20. Pipeline abandonment: a discussion paper on technical and environmental issues

    International Nuclear Information System (INIS)

    Etherington, K.

    1996-01-01

    Formation of government/industry joint steering committee to oversee a review of pipeline abandonment and preparation of a discussion paper was reported. The review became urgent in view of the fact that many of the pipeline systems are nearing the end of their useful life, and the current absence of guidelines in Canada to deal with pipeline abandonment, or to offer guidance on ways of assessing abandonment costs and funding. In view of this situation the safety and the environmental, financial, and legal implications of abandoned pipelines have become an increasing concern to regulatory authorities and the oil and gas industry. Issues to be dealt with in the discussion paper include subsidence, contamination, water crossing, erosion, land management, restoration, utility and pipeline crossings, creation of water conduits, the cost of abandonment, operator choice of abandonment options, and the level of surface disturbance associated with such options

    Patients with medically unexplained physical symptoms suffer from chronic fatigue and/or pain in combination with a variety of other symptoms. A flexible, biopsychosocial approach is needed for diagnostic screening and global management. It is crucial to involve the direct patient environment, including family, friends, colleagues as well as health providers, evaluation, and reintegration sector. The aim of this paper is to review the importance of work in the management of medically unexplained physical symptoms. In this paper, different actors involved explain their views and handling concerning work in the management of MUPS. Symptom severity and lack of understanding from the environment can negatively impact on earning an independent income from labor for years. Work, whether or not paid, is however, an important life domain with positive effects on physical, psychological, and social well-being. Therefore, health actors are pivotal in starting the professional reintegration process as soon as possible and should discuss this item from the early stage onward. Support services can be consulted in mutual interaction as required. A case manager, acting as a central intermediator within this multidisciplinary approach, may promote effective communication and coordination between the patients and their surrounding actors. The professional reintegration process should start as soon as possible within the management of medically unexplained physical symptoms. As such, the care sector, the evaluation sector, and the professional integration sector should collaborate and effectively communicate with each other.

    The lack of technical information from suppliers and from the literature, a wide variety of features and the absence of medical device reference document explain the difficulty for medical and pharmaceutical staffs to choose a central venous catheter (CVC). The aim of this study was to establish the specifications to choose a CVC according to the clinician needs. An analysis of suppliers' technical documentation and a literature review was performed to identify criteria and to collect them in a questionnaire to conduct semi-structured interviews between 1 pharmacist and 5 anaesthesiologists/intensivists. With these interviews, the technical criteria were classified according to their importance in 3 levels. Thirteen technical criteria were identified after reading the technical documents and the literature. Among them, 8 were classified as "essential criteria" (level I) by the physicians: J-shaped guide, one clamp on each way, identified lumen, radiopacity, graduation every centimeter by 5 to 20 cm from the distal extremity, a length of 15 to 25 cm, a single-lumen catheter with a 14 to 16G way and a three-lumen catheter with 14 to 18G way. Finally, three criteria were classified as "intermediate criteria" (level II) and two as "optional criteria" (level III). This collaborative approach allowed to reference new medical devices according to the clinicians needs. These CVC are a mean to respect guidelines for physicians and nurses and to secure the patient's care. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

  7. MDEP Position Paper - PP-STC-01 - MDEP Steering Technical Committee Position Paper on Safety Goals

    International Nuclear Information System (INIS)

    2011-01-01

    In considering the acceptability of a nuclear facility in relation to safety, Governments and regulatory bodies define a range of legal, mandatory requirements which are supplemented by regulatory requirements and expectations which may not have a mandatory nature. The term 'safety goals' is used to cover all health and safety requirements and expectations which must be met: these may be deterministic rules and/or probabilistic targets. They should cover the safety of workers, public and the environment in line with the IAEA's Basic Safety Objective encompassing safety in normal operation through to severe plant states. Although all regulators have safety goals, these are expressed in many different ways and exercises in comparing them frequently are done at a very low level e.g. specific temperature limits in the reactor core. The differences in the requirements from different regulators are difficult to resolve as the goals are derived using different principles and assumptions and are usually for a specific technology. Therefore the Multinational Design Evaluation Programme (MDEP) set up a sub-committee to investigate a different approach. This approach was to start with the high level safety goals and try to derive a structure and means of deriving lower level safety goals that can be seen to be clearly related to the higher level ones. The work will greatly assist in the process of harmonisation of regulatory requirements and enhance coherence and consistency between goals for different technologies. MDEP expects that higher levels of safety will be achieved in the design and operation of new reactors. MDEP strongly supports the structure of safety goals and targets, as set out in this paper, for consideration of its members and IAEA and other organisations, in moving towards international harmonisation of regulatory requirements. MDEP strongly supports the use of integrated decision-making for design evaluation and operational safety. MDEP recognises the need

    Transarterial chemoembolization with Lipiodol (Lipiodol TACE), also called conventional TACE, was developed in the early 1980s and widely adopted worldwide after randomized control trials and meta-analysis demonstrated superiority of Lipiodol TACE to best supportive care. Presently, there is no level one evidence that other TACE techniques are superior to Lipiodol TACE for intermediate stage hepatocellular carcinoma (HCC), which includes patients with preserved liver function and nonsurgical large or multinodular HCC without distant metastases. In addition, TACE is part of the treatment for progressive or symptomatic liver metastases from gastroenteropancreatic neuroendocrine tumors. When injected into the hepatic artery, Lipiodol has the unique property of selective uptake and retention in hyperarterialyzed liver tumors. Lipiodol/drug emulsion followed by particle embolization has been demonstrated to improve the pharmacokinetic of the drug and tumor response. Radio opacity of Lipiodol helps to monitor treatment delivery, with retention of Lipiodol serving as an imaging biomarker for tumor response. For 30 years, Lipiodol TACE has been inconsistently referenced in many publications with various levels of details for the method of preparation and administration, with reported progressive outcomes following improvements in the technique and the devices used to deliver the treatment and better patient selection. Consequently, there is no consensus on the standard method of TACE regarding the use of anticancer agents, embolic material, technical details, and the treatment schedule. In order to develop an internationally validated technical recommendation to standardize the Lipiodol TACE procedure, a worldwide panel of experts participated in a consensus meeting held on May 10, 2014.

    Sepsis is a leading healthcare problem, accounting for the vast majority of fatal events in critically ill patients. Beyond early diagnosis and appropriate treatment, this condition requires a multifaceted approach for monitoring the severity, the potential organ failure as well as the risk of death. Monitoring of the efficacy of treatment is also a major issue in the emergency department (ED). The assessment of critically ill conditions and the prognosis of patients with sepsis is currently based on some scoring systems, which are, however, inefficient to provide definite clues about organ failure and prognosis in general. The discretionary and appropriate use of some selected biomarkers such as procalcitonin, inducible protein 10 (IP10), Group IV phospholipase A2 type II (PLA2 II), neutrophil gelatinase-associated lipocalin (NGAL), natriuretic peptides, mature adrenomedullin (ADM), mid-regional pro-adrenomedullin (MR-proADM), copeptin, thrombopoietin, Mer receptor and even red blood cell distribution width (RDW) represent thereby an appealing perspective in the diagnosis and management of patients with sepsis. Nevertheless, at the moment, it is not still clear if it is better to use a multimarkers approach or if a single, most appropriate, biomarker exists. This collective opinion paper is aimed at providing an overview about the potential clinical usefulness of some innovative biomarkers of sepsis in its diagnosis and prognosis, but also in the treatment management of the disease. This manuscript represents a synopsis of the lectures of Third Italian GREAT Network Congress, that was hold in Rome, 15-19 October 2012.

    Two of the major concerns of the NASA Ames Research Center (NASA ARC) Advisory Committee for Women (ACW) are that recruitment of women scientists, engineers, and technicians needs to increase and that barriers to advancement need to be removed for improved representation of women in middle and upper management and scientific positions. One strategy that addressed this concern was the ACW sponsorship of a Technical Paper Contest for Women at Ames Research Center. Other sponsors of the Contest were the Ames Equal Opportunity Council and the Ames Contractor Council. The Technical Paper Contest for Women greatly increased the visibility of both the civil service women and the women who work for contractors at Ames. The women had the opportunity to hone their written and oral presentation skills. Networking among Ames women increased.

    Technical feasibility has determined the implementation of the paper analysis in forensic documentoscopy. Methods of non-destructive and destructive testing are focused in the study. The dimensions, thickness, opacity, brightness and air permeability are analyzed by the methods of non-destructive testing. The analysis of pH, fiber, humidity and ashes are performed by destructive methods. 10 samples of paper type 'Bond' are examined of the main importers from country. The chemical and anatomy of the wood are explained. The results of the non-destructive methods have achieved to differentiate 8 of the 10 samples studied. The two remaining samples have achieved to differentiate by the fibers analysis and ashes analysis. The pH has determined in the 10 samples that the pulping method has been basic. The technical differentiation of the 'Bond' paper has been possible for use in forensic documentoscopy. The fibers present in the paper are observed applying the dye 'Graff C' and using the microscope. The dye method 'Graff C' has allowed a morphologic differentiation of the organic composition of the sample of paper [es

    1996-01-01

    The U.S. government technical report is a primary means by which the results of federally funded research and development (R&D) are transferred to the U.S. aerospace industry. However, little is known about this information product in terms of its actual use, importance, and value in the transfer of federally funded R&D. Little is also known about the intermediary-based system that is used to transfer the results of federally funded R&D to the U.S. aerospace industry. To help establish a body of knowledge, the U.S. government technical report is being investigated as part of the NASA/DOD Aerospace Knowledge Diffusion Research Project. In this paper, we summarize the literature on the U.S. government technical report and present the results of a survey of U.S. aerospace engineers and scientists that solicited their opinions concerning the format of NASA Langley Research Center (LaRC)-authored technical reports. To learn more about the preferences of U.S. aerospace engineers and scientists concerning the format of NASA LaRC-authored technical reports, we surveyed 133 report producers (i.e., authors) and 137 report users in March-April 1996. Questions covered such topics as (1) the order in which report components are read, (2) components used to determine if a report would be read, (3) those components that could be deleted, (4) the placement of such components as the symbols list, (e) the de-sirability of a table of contents, (5) the format of reference citations, (6) column layout and right margin treatment, and (7) and person and voice. Mail (self-reported) surveys were used to collect the data. The response rates for report producers (i.e., authors) was 68% and for users was 62%.

    Rasmuson, D.M.

    1985-01-01

    The objective of this session, Quantification of Informed Opinion, is to provide the statistician with a better understanding of this important area. The NRC uses informed opinion, sometimes called engineering judgment or subjective judgment, in many areas. Sometimes informed opinion is the only source of information that exists, especially in phenomenological areas, such as steam explosions, where experiments are costly and phenomena are very difficult to measure. There are many degrees of informed opinion. These vary from the weatherman who makes predictions concerning relatively high probability events with a large data base to the phenomenological expert who must use his intuition tempered with basic knowledge and little or no measured data to predict the behavior of events with a low probability of occurrence. The first paper in this session provides the reader with an overview of the subject area. The second paper provides some aspects that must be considered in the collection of informed opinion to improve the quality of the information. The final paper contains an example of the use of informed opinion in the area of seismic hazard characterization. These papers should be useful to researchers and statisticians who need to collect and use informed opinion in their work

    In fiscal year 1994, the United States government spent about $68 billion for science and technology. Although there is general agreement among policy makers that the results of this expenditure can be used to enhance technological innovation and improve economic competitiveness, there is no coherent scientific and technical information (STI) policy. The absence of a cohesive policy and STI policy framework means that the transfer and utilization of STI goes uncoordinated. This chapter examines the U.S. government's role in funding science and technology, reviews Federal STI activities and involvement in the transfer and use of STI resulting from federally-funded science and technology, presents issues surrounding the use of federally-funded STI, and offers recommendations for improving the transfer and use of STI.

    1987-01-01

    In order to effectively meet its responsibility to protect the public health and safety, the Nuclear Regulatory Commission (NRC) nuclear power plant licensing and inspection programs respond to potential technical deficiencies identified by conference and professional society meeting papers when deemed appropriate. The NRC staff's response mechanisms for such technical deficiencies include: generic letters, Bulletins, Information Notices, Standard Review Plan (NUREG-0800) revisions, docketed Final Safety Analysis Report (FSAR) questions, special studies, special (reactive) inspection, and inspection program revisions. This paper describes reactive inspection efforts by Region III in response to potential technical deficiencies identified in recent air cleaning conference papers, including: post-accident effluent sample line deposition losses; failure to implement good engineering practices in the design, construction, and testing of Nuclear Air Treatment Systems (NATS); filter bypass via filter housing drain lines; spinster carbon degradation; use of silicone sealants and other temporary patching material in NATS; filter housing fire protection deluge system problems; lack of charcoal batch traceability; Quality Assurance records problems involving equipment, vendor, filter, and personnel qualifications; inadequate ANSI/ASME N510 acceptance criteria and tests; and failure to adequately demonstrate control room habitability per 10 CFR 50, Appendix A, General Design Criterion-19. Region III inspections indicate that many of these deficiencies appear to be prevalent. Inspection findings and utility responses to the findings are discussed. NRC Region III and Headquarters programmatic reactions to the identified generic problem areas are also discussed

  1. Counting Highly Cited Papers for University Research Assessment: Conceptual and Technical Issues

    Science.gov (United States)

    Rodríguez-Navarro, Alonso

    2012-01-01

    A Kuhnian approach to research assessment requires us to consider that the important scientific breakthroughs that drive scientific progress are infrequent and that the progress of science does not depend on normal research. Consequently, indicators of research performance based on the total number of papers do not accurately measure scientific progress. Similarly, those universities with the best reputations in terms of scientific progress differ widely from other universities in terms of the scale of investments made in research and in the higher concentrations of outstanding scientists present, but less so in terms of the total number of papers or citations. This study argues that indicators for the 1% high-citation tail of the citation distribution reveal the contribution of universities to the progress of science and provide quantifiable justification for the large investments in research made by elite research universities. In this tail, which follows a power low, the number of the less frequent and highly cited important breakthroughs can be predicted from the frequencies of papers in the upper part of the tail. This study quantifies the false impression of excellence produced by multinational papers, and by other types of papers that do not contribute to the progress of science. Many of these papers are concentrated in and dominate lists of highly cited papers, especially in lower-ranked universities. The h-index obscures the differences between higher- and lower-ranked universities because the proportion of h-core papers in the 1% high-citation tail is not proportional to the value of the h-index.

    Energy Technology Data Exchange (ETDEWEB)

    Fitzpatrick, Stephen W.

    2002-04-23

    This project involved a three-year program managed by BioMetics, Inc. (Waltham, MA) to demonstrate the commercial feasibility of Biofine thermochemical process technology for conversion of cellulose-containing wastes or renewable materials into levulinic acid, a versatile platform chemical. The program, commencing in October 1995, involved the design, procurement, construction and operation of a plant utilizing the Biofine process to convert 1 dry ton per day of paper sludge waste. The plant was successfully designed, constructed, and commissioned in 1997. It was operated for a period of one year on paper sludge from a variety of source paper mills to collect data to verify the design for a commercial scale plant. Operational results were obtained for four different feedstock varieties. Stable, continuous operation was achieved for two of the feedstocks. Continuous operation of the plant at demonstration scale provided the opportunity for process optimization, development of operational protocols, operator training and identification of suitable materials of construction for scale up to commercial operation . Separated fiber from municipal waster was also successfully processed. The project team consisted of BioMetics Inc., Great Lakes Chemical Corporation (West Lafayette, IN), and New York State Energy Research and Development Authority (Albany, NY).

    The early precursors of laser ultrasonics on paper were Prof. Y. Berthelot from the Georgia Institute of Technology/Mechanical Engineering department, and Prof. P. Brodeur from the Institute of Paper Science and Technology, both located in Atlanta, Georgia. The first Ph.D. thesis that shed quite some light on the topic, but also left some questions unanswered, was completed by Mont A. Johnson in 1996. Mont Johnson was Prof. Berthelot's student at Georgia Tech. In 1997 P. Brodeur proposed a project involving himself, Y. Berthelot, Dr. Ken Telschow and Mr. Vance Deason from INL, Honeywell-Measurex and Dr. Rick Russo from LBNL. The first time the proposal was not accepted and P. Brodeur decided to re-propose it without the involvement from LBNL. Rick Russo proposed a separate project on the same topic on his side. Both proposals were finally accepted and work started in the fall of 1997 on the two projects. Early on, the biggest challenge was to find an optical detection method which could detect laser-induced displacements of the web surface that are of the order of .1 micron in the ultrasonic range. This was to be done while the web was having an out-of-plane amplitude of motion in the mm range due to web flutter; while moving at 10 m/s to 30 m/s in the plane of the web, on the paper machine. Both teams grappled with the same problems and tried similar methods in some cases, but came up with two similar but different solutions one year later. The IPST, GT, INL team found that an interferometer made by Lasson Technologies Inc. using the photo-induced electro-motive force in Gallium Arsenide was able to detect ultrasonic waves up to 12-15 m/s. It also developed in house an interferometer using the Two-Wave Mixing effect in photorefractive crystals that showed good promises for on-line applications, and experimented with a scanning mirror to reduce motion-induced texture noise from the web and improve signal to noise ratio. On its side, LBNL had the idea to

    2009-07-01

    The Navigable Waters Protection Act (NWPA) was designed to ensure a balance between public rights of navigation and the need to build bridges, dams, and other structures. This paper discussed an owner's guide to navigation safety around water control structures. Developed by Transport Canada, the guide was intended to help owners of water control structures address boating safety matters and assist owners in making applications under the NWPA. The guide was prepared to address amendments made to the NWPA in 2009 as well as to assist owners in identifying potential hazards and interactions by the boating public at water control structures. The guide included information related to signage; navigation aids; barriers and booms; warning alerts and alarms; portage and access around structures; and application requirements. It was concluded that the guide will also provide a summary of legislation that may affect owners of water control structures.

    2011-01-01

    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...

    Technical standards are of great importance for the closer definition of inexact terms of law, for instance ''generally accepted technical rules'', ''state of the art'', ''state of science and technology'' or similar normative terms, in the law of technical safety. The paper discusses with whom the authority for regulating this sector of law rests, deals with the different ways of how technical standards are used by the law (''anticipated expert opinion'', reference to such standards in law and administration) and points out demands on the procedure of standardization.

    As part of Phase 4 of the NASA/DOD Aerospace Knowledge Diffusion Project, two studies were conducted that investigated the technical communications practices of Russian and U.S. aerospace engineers and scientists. Both studies have the same five objectives: first, to solicit the opinions of aerospace engineers and scientists regarding the importance of technical communications to their profession; second, to determine the use and production of technical communications by aerospace engineers and scientists; third, to seek their views about the appropriate content of an undergraduate course in technical communications; fourth, to determine aerospace engineers' and scientists' use of libraries, technical information centers, and on-line data bases; and fifth, to determine the use and importance of computer and information technology to them. A self-administered questionnaire was distributed to aerospace engineers and scientists at the Central Aero-Hydrodynamic Institute (TsAGI), NASA ARC, and NASA LaRC. The completion rates for the Russian and U.S. surveys were 64 and 61 percent, respectively. The responses of the Russian and U.S. participants, to selected questions, are presented in this report.

    2016-01-01

    Migration of chemicals from packaging materials to foods may lead to human exposure. Polyfluoroalkyl substances (PFAS) can be used in technical mixtures (TMs) for use in food packaging of paper and board, and PFAS have been detected in human serum and umbilical cord blood. The specific structures...... of the PFAS in TMs are often unknown, but polyfluorinated alkyl phosphate esters (PAPs) have been characterized in TMs, food packaging, and in food. PAPs can be metabolized into fluorotelomer alcohols (FTOHs) and perfluoroalkyl carboxylic acids (PFCAs). Some PFAS have endocrine activities, highlighting...... the need to investigate these effects. Herein, we studied the endocrine activity of less characterized PFAS, including short-chain PFCAs and FTOHs, PAPs, and TMs of unknown chemical composition. Long-chain PFCAs were also included. We applied seven assays covering effects on estrogen, glucocorticoid...

    International Nuclear Information System (INIS)

    2007-01-01

    Over the past two decades, the IAEA has conducted a series of major conferences that have addressed topical issues and strategies critical to nuclear safety for consideration by the world's nuclear regulators. More recently, the IAEA organized the International Conference on Effective Nuclear Regulatory Systems - Facing Safety and Security Challenges, held in Moscow in 2006. The Moscow conference was the first of its kind, because it brought together senior regulators of nuclear safety, radiation safety and security from around the world to discuss how to improve regulatory effectiveness with the objective of improving the protection of the public and the users of nuclear and radioactive material. The International Conference on Challenges Faced by Technical and Scientific Support Organizations in Enhancing Nuclear Safety was held in Aix-en-Provence, France, from 23 to 27 April 2007. This conference, again, was the first of its kind, because it was the first to address technical and scientific support organizations (TSOs), the role they play in supporting either the national regulatory bodies or the industry in making optimum safety decisions and the challenges they face in providing this support. This conference provided a forum for the TSOs to discuss these and other issues with the organizations to which they provide this support - that is, the regulators and the operators/industry - as well as with other stakeholders such as research organizations and public authorities. This conference can also be considered to have a link to the Moscow conference. The Moscow conference concluded that effective regulation of nuclear safety is vital for the safe use of nuclear energy and associated technologies, both now and in the future, and is an essential prerequisite for establishing an effective Global Nuclear Safety Regime. The Moscow conference also highlighted the importance of continued and improved international cooperation in the area of nuclear safety. These

    1997-01-01

    The U.S. government technical report is a primary means by which the results of federally funded research and development (R&D) are transferred to the U.S. aerospace industry. However, little is known about this information product in terms of its actual use, importance, and value in the transfer of federally funded R&D. Little is also known about the intermediary-based system that is used to transfer the results of federally funded R&D to the U.S. aerospace industry. To help establish a body of knowledge, the U.S. government technical report is being investigated as part of the NASA/DoD Aerospace Knowledge Diffusion Research Project. In this article, we summarize the literature on the U.S. government technical report and present the results of a survey of U.S. aerospace engineers and scientists that solicited their opinions concerning the format of NASA Langley Research Center (LaRC)-authored technical reports. To learn more about the preferences of U.S. aerospace engineers and scientists concerning the format of NASA LaRC-authored technical reports, we surveyed 133 report producers (i.e., authors) and 137 report users in March-April 1996. Questions covered such topics as: (a) the order in which report components are read; (b) components used to determine if a report would be read; (c) those components that could be deleted; (d) the placement of such components as the symbols list; (e) the desirability of a table of contents; (f) the format of reference citations; (g) column layout and right margin treatment; and (h) writing style in terms of person and voice. Mail (self-reported) surveys were used to collect the data. The response rates for report producers (i.e., authors) was 68% and for users was 62%.

    Heart failure (HF) care takes place in multiple settings, with a variety of providers, and generally involves patients who have multiple comorbidities. This situation is a "perfect storm" of factors that predispose patients to medication errors. The goals of this paper are to outline potential roles for clinical pharmacists in a multidisciplinary HF team, to document outcomes associated with interventions by clinical pharmacists, to recommend minimum training for clinical pharmacists engaged in HF care, and to suggest financial strategies to support clinical pharmacy services within a multidisciplinary team. As patients transition from inpatient to outpatient settings and between multiple caregivers, pharmacists can positively affect medication reconciliation and education, assure consistency in management that results in improvements in patient satisfaction and medication adherence, and reduce medication errors. For mechanical circulatory support and heart transplant teams, the Centers for Medicare and Medicaid Services considers the participation of a transplant pharmacology expert (e.g., clinical pharmacist) to be a requirement for accreditation, given the highly specialized and complex drug regimens used. Although reports of outcomes from pharmacist interventions have been mixed owing to differences in study design, benefits such as increased use of evidence-based therapies, decreases in HF hospitalizations and emergency department visits, and decreases in all-cause readmissions have been demonstrated. Clinical pharmacists participating in HF or heart transplant teams should have completed specialized postdoctoral training in the form of residencies and/or fellowships in cardiovascular and/or transplant pharmacotherapy, and board certification is recommended. Financial mechanisms to support pharmacist participation in the HF teams are variable. Positive outcomes associated with clinical pharmacist activities support the value of making this resource available

    As part of Phase 4 of the NASA/DOD Aerospace Knowledge Diffusion Research Project, two studies were conducted that investigated the technical communications practices of Dutch and U.S. aerospace engineers and scientists. A self-administered questionnaire was distributed to aerospace engineers and scientists at the National Aerospace Laboratory (The Netherlands), and NASA ARC (U.S.), and NASA LaRC (U.S.). This paper presents responses of the Dutch and U.S. participants to selected questions concerning four of the seven project objectives: determining the importance of technical communications to aerospace engineering professionals, investigating the production of technical communications, examining the use and importance of computer and information technology, and exploring the use of electronic networks.

    This paper reports the results of an exploratory study that investigated the influence of technical uncertainty on the use of information and information sources by U.S. industry-affiliated aerospace engineers and scientists in completing or solving a project, task, or problem. Data were collected through a self-administered questionnaire. Survey participants were U.S. aerospace engineers and scientists whose names appeared on the Society of Automotive Engineers (SAE) mailing list. The results support the findings of previous research and the following study assumptions. Information and information-source use differ for projects, problems, and tasks with high and low technical uncertainty. As technical uncertainty increases, information-source use changes from internal to external and from informal to formal sources. As technical uncertainty increases, so too does the use of federally funded aerospace research and development (R&D). The use of formal information sources to learn about federally funded aerospace R&D differs for projects, problems, and tasks with high and low technical uncertainty.

    This paper describes the preliminary analysis of a survey of the American Institute of Aeronautics and Astronautics (AIAA) student members. In the paper we examine (1) the demographic characteristics of the students, (2) factors that affected their career decisions, (3) their career goals and aspirations, and (4) their training in technical communication and techniques for finding and using aerospace scientific and technical information (STI). We determine that aerospace engineering students receive training in technical communication skills and the use of STI. While those in the aerospace industry think that more training is needed, we believe the students receive the appropriate amount of training. We think that the differences between the amount of training students receive and the perception of training needs is related partially to the characteristics of the students and partially to the structure of the aerospace STI dissemination system. Overall, we conclude that the students' technical communication training and knowledge of STI, while limited by external forces, makes it difficult for students to achieve their career goals.

    1991-01-01

    Aerospace engineers and scientists from Western Europe, Japan, and the United States were surveyed as part of the NASA/DoD Aerospace Knowledge Diffusion Research Project. Questionnaires were used to solicit their opinions regarding the following: (1) the importance of technical communications to their profession; (2) the use and production of technical communications; and (3) their views about the appropriate content of an undergraduate course in technical communications. The ability to communicate technical information effectively was very important to the aerospace engineers and scientists who participated in the study. A considerable portion of their working week is devoted to using and producing technical information. The types of technical communications used and produced varied within and among the three groups. The type of technical communication product used and produced appears to be related to respondents' professional duties. Respondents from the three groups made similar recommendations regarding the principles, mechanics, and on-the-job communications to be included in an undergraduate technical communications course for aerospace majors.

    International Nuclear Information System (INIS)

    Farinelli, U.

    1979-01-01

    The International Nuclear Fuel Cycle Evaluation (INFCE) has not generated any very new idea in terms of reactors or fuel cycles. Its very subdivision into working groups, which for the most part represent the traditional subdivisions of the fuel cycle, and the absence of a full-time international working team for the evaluation, have been obstacles in this direction. Moreover, evaluation based on studies and extrapolations has very little ultimate value; a realistic assessment requires such a detailed analysis that it can only be performed on small variations of present systems. Proliferation characteristics of various fuel cycles have proven more difficult to evaluate than was previously thought. First, proliferation is mainly a short-term issue, and not many solutions are applicable within this time horizon (20 or 25 years); second, traditional criteria to classify proliferation resistance have become less rigid at closer scrutiny; and finally, it is difficult to assess the effectiveness of technical antiproliferation measures without considering the political actions attached to them. The result is that the two basic strategies of the USA (based on the once-through fuel cycle in light water reactors and postponing decisions on more advanced solutions) and of Western Europe and Japan (based on fuel reprocessing and early deployment of fast breeders) have remained the only realistic options under discussion. However, changes are taking place in each strategy to make the one less wasteful of fuel and the other more protected for proliferation, and it is reasonable to suppose that they will be able to co-exist in the future.

    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

    1997-01-01

    Economists, management theorists, business strategists, and governments alike recognize knowledge as the single most important resource in today's global economy. Because of its relationship to technological progress and economic growth, many governments have taken a keen interest in knowledge; specifically its production, transfer, and use. This paper focuses on the technical report as a product for disseminating the results of aerospace research and development (R&D) and its use and importance to aerospace engineers and scientists. The emergence of knowledge as an intellectual asset, its relationship to innovation, and its importance in a global economy provides the context for the paper. The relationships between government and knowledge and government and innovation are used to place knowledge within the context of publicly-funded R&D. Data, including the reader preferences of NASA technical reports, are derived from the NASA/DoD Aerospace Knowledge Diffusion Research Project, a ten-year study of knowledge diffusion in the U.S. aerospace industry.

    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.

  7. Opinion Summarizationof CustomerComments

    Fan, Miao; Wu, Guoshi

    Web 2.0 technologies have enabled more and more customers to freely comment on different kinds of entities, such as sellers, products and services. The large scale of information poses the need and challenge of automatic summarization. In many cases, each of the user-generated short comments implies the opinions which rate the target entity. In this paper, we aim to mine and to summarize all the customer comments of a product. The algorithm proposed in this researchis more reliable on opinion identification because it is unsupervised and the accuracy of the result improves as the number of comments increases. Our research is performed in four steps: (1) mining the frequent aspects of a product that have been commented on by customers; (2) mining the infrequent aspects of a product which have been commented by customers (3) identifying opinion words in each comment and deciding whether each opinion word is positive, negative or neutral; (4) summarizing the comments. This paper proposes several novel techniques to perform these tasks. Our experimental results using comments of a number of products sold online demonstrate the effectiveness of the techniques.

    The research proves that persuasion has two types of objectives. Its main objective is the change of opinion. Its fundamental and foundational objectives are the change in attitude, generic conduct and situational behaviour. The main objective controls the fundamental objectives. The change in attitudes and conduct/behaviour is presided by changes in opinion. Persuasion is thus shown to be primarily and ultimately a matter of opinion. As such, its mechanism to manage and generate ...

    Social acquaintance networks influenced by social culture and social policy have a great impact on public opinion evolution in daily life. Based on the differences between socio-culture and social policy, three different social acquaintance networks (kinship-priority acquaintance network, independence-priority acquaintance network, and hybrid acquaintance network) incorporating heredity proportion p h and variation proportion p v are proposed in this paper. Numerical experiments are conducted to investigate network topology and different phenomena during opinion evolution, using the Deffuant model. We found that in kinship-priority acquaintance networks, similar to the Chinese traditional acquaintance networks, opinions always achieve fragmentation, resulting in the formation of multiple large clusters and many small clusters due to the fact that individuals believe more in their relatives and live in a relatively closed environment. In independence-priority acquaintance networks, similar to Western acquaintance networks, the results are similar to those in the kinship-priority acquaintance network. In hybrid acquaintance networks, similar to the Chinese modern acquaintance networks, only a few clusters are formed indicating that in modern China, opinions are more likely to reach consensus on a large scale. These results are similar to the opinion evolution phenomena in modern society, proving the rationality and applicability of network models combined with social culture and policy. We also found a threshold curve p v +2p h =2.05 in the results for the final opinion clusters and evolution time. Above the threshold curve, opinions could easily reach consensus. Based on the above experimental results, a culture-policy-driven mechanism for the opinion dynamic is worth promoting in this paper, that is, opinion dynamics can be driven by different social cultures and policies through the influence of heredity and variation in interpersonal relationship networks.

    To understand the diffusion of aerospace knowledge, it is necessary to understand the communications practices and the information-seeking behaviors of those involved in the production, transfer, and use of aerospace knowledge at the individual, organizational, national, and international levels. In this paper, we report selected results from a survey of Japanese and U.S. aerospace engineers and scientists that focused on communications practices and information-seeking behaviors in the workplace. Data are presented for the following topics: importance of and time spent communicating information, collaborative writing, need for an undergraduate course in technical communications, use of libraries, the use and importance of electronic (computer) networks, and the use and importance of foreign and domestically produced technical reports. The responses of the survey respondents are placed within the context of the Japanese culture. We assume that differences in Japanese and U.S. cultures influence the communications practices and information-seeking behaviors of Japanese and U.S. aerospace engineers and scientists.

    With its contribution to trade, its coupling with national security, and its symbolism of U.S. technological strength, the U.S. aerospace industry holds a unique position in the Nation's industrial structure. Federal science and technology policy and Federal scientific and technical information (STI) policy loom important as strategic contributions to the U.S. aerospace industry's leading competitive position. However, three fundamental policy problems exist. First, the United States lacks a coherent STI policy and a unified approach to the development of such a policy. Second, policymakers fail to understand the relationship of STI to science and technology policy. Third, STI is treated as a part of general information policy, without any recognition of its uniqueness. This paper provides an overview of the Federal information policy structure as it relates to STI and frames the policy issues that require resolution.

    Government technology policy has nurtured the growth of the aerospace industry which is vital to both the U.S. and Japanese economies. Japanese technology policy differs significantly from U.S. technology policy, however, particularly with respect to the production, transfer, and use of scientific and technical information (STI). In this paper, we discuss the unique position of the aerospace industry in the U.S. and Japan, U.S. and Japanese aerospace policy, and the role of STI in the process of aerospace innovation. The information-seeking behaviors of U.S. and Japanese aerospace engineers and scientists are compared. The authors advocate the development of innovation-adoption technology and STI policy goals for U.S. aerospace and the inclusion of an aerospace knowledge diffusion transfer system with an 'active' component for scanning and acquiring foreign aerospace technology and STI.

    The U.S. aerospace industry has a long history of federal support for research related to its needs. Since the establishment of the National Advisory Committee for Aeronautics (NACA) in 1915, the federal government has provided continuous research support related to flight and aircraft design. This research has contributed to the international preeminence of the U.S. aerospace industry. In this paper, we present a sociological analysis of aerospace engineers and scientists and how their attitudes and behaviors impact the flow of scientific and technical information (STI). We use a constructivist framework to explain the spotty dissemination of federally funded aerospace research. Our research is aimed towards providing federal policymakers with a clearer understanding of how and when federally funded aerospace research is used. This understanding will help policymakers design improved information transfer systems that will aid the competitiveness of the U.S. aerospace industry.

    One of the most significant developments in the field of technical communication during the 1980's and 1990's has been a growing interest in international technical communication, including technical communication in Japan. This article provides insights into aspects of the Japanese language and culture that affect Japanese technical communication practices. These insights are then used to interpret and report the results of a survey of Japanese aerospace engineers and scientists concerning the kinds of communication products they produce, the kinds they use, and the specific recommendation they would offer to designers of academic programs in technical communication.

    Murphy, Daniel J.; Pinelli, Thomas E.

    1994-01-01

    This paper discusses the use of computers as a medium for communication (CMC) used by aerospace engineers and scientists to obtain and/or provide technical information related to research and development activities. The data were obtained from a questionnaire survey that yielded 1006 mail responses. In addition to communication media, the research also investigates degrees of task uncertainty, environmental complexity, and other relevant variables that can affect aerospace workers' information-seeking strategies. While findings indicate that many individuals report CMC is an important function in their communication patterns, the research indicates that CMC is used less often and deemed less valuable than other more conventional media, such as paper documents, group meetings, telephone and face-to-face conversations. Fewer than one third of the individuals in the survey account for nearly eighty percent of the reported CMC use, and another twenty percent indicate they do not use the medium at all, its availability notwithstanding. These preliminary findings suggest that CMC is not as pervasive a communication medium among aerospace workers as the researcher expect a priori. The reasons underlying the reported media use are not yet fully known, and this suggests that continuing research in this area may be valuable.

    Until the recent dissolution of the Soviet Union, the Communist Party exerted a strict control of access to and dissemination of scientific and technical information (STI). This article presents models of the Soviet-style information society and the Western-style information society and discusses the effects of centralized governmental control of information on Russian technical communication practices. The effects of political control on technical communication are then used to interpret the results of a survey of Russian and U.S. aerospace engineers and scientists concerning the time devoted to technical communication, their collaborative writing practices and their attitudes toward collaboration, the kinds of technical documents they produce and use, their views regarding the appropriate content for an undergraduate technical communication course, and their use of computer technology. Finally, the implications of these findings for future collaboration between Russian and U.S. engineers and scientists are examined.

    When engineering students graduate and enter the world of work, they make the transition from an academic to a professional community of knowledge. The importance of oral and written communication to the professional success and advancement of engineers is well documented. For example, studies such as those conducted by Mailloux (1989) indicate that communicating data, information, and knowledge takes up as much as 80% of an engineer's time. However, these same studies also indicate that many engineering graduates cannot (a) write technical reports that effectively inform and influence decisionmaking, (b) present their ideas persuasively, and (c) communicate with their peers. If these statements are true, how is learning to communicate effectively in their professional knowledge community different for engineering students educated in the United States but who come from other cultures-cultures in which English is not the primary language of communication? Answering this question requires adequate and generalizable data about these students' communications abilities, skills, and competencies. To contribute to the answer, we undertook a national (mail) survey of 1,727 student members of the American Institute of Aeronautics and Astronautics (AIAA). The focus of our analysis and this paper is a comparison of the responses of 297 student members for whom English is a second language with the responses of 1,430 native English speaking students to queries regarding career choice, bilingualism and language fluency, communication skills, collaborative writing, computer use, and the use of electronic (computer) networks.

    The Internet forms a platform featured with high liquidity, accessibility and concealment for the public to express their respective views on certain events, thus leading to a large network graph. Due to such environmental features, the public opinions formed on the Internet are different from those on traditional media. Studies focusing on the former area are relatively fewer. In addition, the majority of existing methods proposed for constructing the Internet public opinion topological structure are based on the classic BA model, thus resulting in drawbacks in the range of simplicity and a lack of strict deduction. Therefore, based on the complex networks theory, a model applied to describe the topology of the Internet public opinion is deduced with rigorous derivation in the present paper. Results show that the proposed expression could well reflect the degree distribution of Internet public opinion which follows an analogous power law distribution, and that the peak value and the degree distribution are not correlative to each other. Moreover, it has been also proved that compared to the classic BA model, the proposed model has better accuracy performance in the description of the degree distribution of the Internet public opinion, which contributes to future studies focusing on this area. Thus, an attempt has been made to give the first theoretical description of the Internet public opinion topology in the present paper. In addition, it is also the first paper focusing on the solution of networks degree distribution with an exponential growth form.

    A study was undertaken to investigate the relationship between the use of U.S. government technical reports by U.S. aerospace engineers and scientists and seven selected sociometric variables. Data were collected by means of a self-administered mail survey which was distributed to a randomly drawn sample of American Institute of Aeronautics and Astronautics (AIAA) members. Two research questions concerning the use of conference meeting papers, journal articles, in-house technical reports, and U.S. government technical reports were investigated. Relevance, technical quality, and accessibility were found to be more important determinants of the overall extent to which U.S. government technical reports and three other information products were used by U.S. aerospace engineers and scientists.

    This book is a sort of tribute to Rob Clifton (1964-2002), Associate Professor of Philosophy and Associate Director of the Center for Philosophy of Science at the University of Pittsburgh, philosopher of physics and editor of the journal Studies in the History and Philosophy of Modern Physics, who tragically died of cancer. It contains fourteen papers by Clifton, for the most part written in collaboration with other authors (Jeffrey Bub (2), Sheldon Goldstein, Michael Dickson, Hans Halvorson (6), Adrian Kent (2)), published between 1995 and 2002. The choice of papers made by the editors is very impressive. They concern the foundations of quantum mechanics and quantum field theory. Among the issues discussed are the modal interpretations of quantum mechanics, the problems of hidden variables theories, non-locality, Bell's inequality, the Einstein-Podolsky-Rosen paradox, Lorentz invariance, de-coherence, non-contextuality, complementarity, entanglement and quantum information. A consequence of such investigations is that non-separability is a more complex issue than violation of Bell's inequality. Apart from the perspective one can follow-whether one agrees or not with Clifton-these papers are effective contributions to an understanding of the problems involved in the foundations of quantum mechanics. The most interesting parts, in my opinion, are related to the extension of the discussion of foundational problems to quantum field theory: on the algebraic approach, and on the twin concepts of particle and vacuum. Non-locality appears to be 'worse' in relativistic quantum field theory than in non-relativistic quantum mechanics. All the papers deal with relevant epistemological and even historical aspects of quantum mechanics interpretations, but all the issues are discussed from a technical, logical and mathematical approach. A complete bibliography of Clifton's papers is given at the end of the volume. (book review)

    Public opinion, especially the online public opinion is a critical issue when it comes to mining its characteristics. Because it can be formed directly and intensely in a short time, and may lead to the outbreak of online group events, and the formation of online public opinion crisis. This may become the pushing hand of a public crisis event, or even have negative social impacts, which brings great challenges to the government management. Data from the mass media which reveal implicit, previously unknown, and potentially valuable information, can effectively help us to understand the evolution law of public opinion, and provide a useful reference for rumor intervention. Based on the Dynamic Network Analysis method, this paper uses ORA software to mine characteristics of public opinion information, opinion topics, and public opinion agents through a series of indicators, and quantitatively analyzed the relationships between them. The results show that through the analysis of the 8 indexes associating with opinion data mining, we can have a basic understanding of the public opinion characteristics of an opinion event, such as who is important in the opinion spreading process, the information grasping condition, and the opinion topics release situation.

    Rohingya is an ethnicity in Myanmar. Recently there was a conflict in the area between the Rakhine population and the Myanmar army. Many opinions are pro and contra in addressing this issue. There is a critic, there is a support and there is a neutral. The purpose of this paper is to analyze the world public opinion about the case of Rohingya. The opinion data to be processed is taken from twitter. the reason for using twitter is because twitter has become one of the popular social media and includes the most frequently visited social media. Therefore, it would be a lot of data that can be taken from twitter to be processed in the process of sentiment analysis. The grouping of opinions will be divided into 3 parts of positive, negative and neutral. the method used in grouping is the naïve Bayes method.

    Migration of chemicals from packaging materials to foods may lead to human exposure. Polyfluoroalkyl substances (PFAS) can be used in technical mixtures (TMs) for use in food packaging of paper and board, and PFAS have been detected in human serum and umbilical cord blood. The specific structures of the PFAS in TMs are often unknown, but polyfluorinated alkyl phosphate esters (PAPs) have been characterized in TMs, food packaging, and in food. PAPs can be metabolized into fluorotelomer alcohols (FTOHs) and perfluoroalkyl carboxylic acids (PFCAs). Some PFAS have endocrine activities, highlighting the need to investigate these effects. Herein, we studied the endocrine activity of less characterized PFAS, including short-chain PFCAs and FTOHs, PAPs, and TMs of unknown chemical composition. Long-chain PFCAs were also included. We applied seven assays covering effects on estrogen, glucocorticoid, androgen, and peroxisome proliferator-activated receptor (PPAR) activity, as well as steroidogenesis in vitro and ex vivo. In general, PAPs, FTOHs, TMs, and long-chain PFCAs showed estrogenic activity through receptor activation and/or increasing 17β-estradiol levels. Furthermore, short- and long-chain PFCAs activated PPARα and PPARγ. Collectively, this means that (i) PAPs, FTOHs, and PFCAs exhibit endocrine activity through distinct and sometimes different mechanisms, (ii) two out of three tested TMs exhibited estrogenic activity, and (iii) short-chain FTOHs showed estrogenic activity and short-chain PFCAs generally activate both PPARα and PPARγ with similar potency and efficacy as long-chain PFCAs. In conclusion, several new and divergent toxicological targets were identified for different groups of PFAS. © 2016 American Society of Andrology and European Academy of Andrology.

  12. Anisotropic opinion dynamics

    Neirotti, Juan

    2016-07-01

    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 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.

    The rapid development of Web technology has resulted in an increasing number of hotel customers sharing their opinions on the hotel services. Effective visual analysis of online customer opinions is needed, as it has a significant impact on building a successful business. In this paper, we present OpinionSeer, an interactive visualization system that could visually analyze a large collection of online hotel customer reviews. The system is built on a new visualization-centric opinion mining technique that considers uncertainty for faithfully modeling and analyzing customer opinions. A new visual representation is developed to convey customer opinions by augmenting well-established scatterplots and radial visualization. To provide multiple-level exploration, we introduce subjective logic to handle and organize subjective opinions with degrees of uncertainty. Several case studies illustrate the effectiveness and usefulness of OpinionSeer on analyzing relationships among multiple data dimensions and comparing opinions of different groups. Aside from data on hotel customer feedback, OpinionSeer could also be applied to visually analyze customer opinions on other products or services.

    Nuclear Training Center (ICJT) at the Jozef Stefan Institute is actively involved also in public information of nuclear issues in Slovenia. After the accident in Fukushima ICJT was one of the main sources of technical information and explanation for the journalists. Organized groups, mainly schoolchildren, traditionally come to ICJT, where they listen to a live lecture and visit the permanent exhibition on nuclear energy. Each year in spring, around 1000 of visitors are polled regarding their knowledge and attitude towards nuclear energy. As the visitors of ICJT are not a representative sample of general population, the results of the poll can not be taken absolutely, but they are valuable when compared to previous years' results - to monitor trends in the (younger) public. In the year 2011, the poll was conducted one month after the accident in Fukushima. ICJT is also analysing media reports by following articles in all types of media: TV, radio, press and web. The first two months after the Fukushima accident the frequency of reports increased drastically and then slowly faded away to reach pre-accident level in about 6 months. Naturally there were a lot of concerned reports, some of them also very negative, but given the circumstances and compared with some other countries, e.g. Austria or Germany, the reporting was relatively objective. The paper will analyze the trends in public opinion in Slovenia based on direct contacts with journalists, opinion polls and media analyses.(author).

    The topic of the behaviour of energetic alpha particles in magnetic fusion confined plasmas is perhaps the ultimate frontier plasma physics issue that needs to be understood in the quest to achieve controlled power from the fusion reaction in magnetically confined plasmas. The partial pressure of alpha particles in a burning plasma will be ~5-10% of the total pressure and under these conditions the alpha particles may be prone to develop instability through Alfvénic interaction. This may lead, even with moderate alpha particle loss, to a burn quench or severe wall damage. Alternatively, benign Alfvénic signals may allow the vital information to control a fusion burn. The significance of this issue has led to extensive international investigations and a biannual meeting that began in Kyiv in 1989, followed by subsequent meetings in Aspenäs (1991), Trieste (1993), Princeton (1995), JET/Abingdon (1997), Naka (1999), Gothenburg (2001), San Diego (2003), Takayama (2005), Kloster Seeon (2007) and Kyiv (2009). The meeting was initially entitled 'Alpha Particles in Fusion Research' and then was changed during the 1997 meeting to 'Energetic Particles in Magnetic Confinement Systems' in appreciation of the need to study the significance of the electron runaway, which can lead to the production of energetic electrons with energies that can even exceed the energy produced by fusion products. This special issue presents some of the mature interesting work that was reported at the 12th IAEA Technical Meeting on Energetic Particles in Magnetic Confinement Systems, which was held in Austin, Texas, USA (7-11 September 2011). This meeting immediately followed a related meeting, the 5th IAEA Technical Meeting on Theory of Plasma Wave Instabilities (5-7 September 2011). The meetings shared one day (7 September 2011) with presentations relevant to both groups. The presentations from most of the participants, as well as some preliminary versions of papers, are available at the

    The project examines how the results of NASA/DOD research diffuse into the aerospace R&D process, and empirically analyzes the implications of the aerospace knowledge diffusion process. Specific issues considered are the roles played by government technical reports, the recognition of the value of scientific and technical information (STI), and the optimization of the STI aerospace transfer system. Information-seeking habits are assessed for the U.S. aerospace community, the general community, the academic sector, and the international community. U.S. aerospace engineers and scientists use 65 percent of working time to communicate STI, and prefer 'internal' STI over 'external' STI. The isolation from 'external' information is found to be detrimental to U.S. aerospace R&D in general.

    2017-08-01

    To reveal heterogeneous behaviors of opinion evolution in different scenarios, we propose an opinion model with topic interactions. Individual opinions and topic features are represented by a multidimensional vector. We measure an agent's action towards a specific topic by the product of opinion and topic feature. When pairs of agents interact for a topic, their actions are introduced to opinion updates with bounded confidence. Simulation results show that a transition from a disordered state to a consensus state occurs at a critical point of the tolerance threshold, which depends on the opinion dimension. The critical point increases as the dimension of opinions increases. Multiple topics promote opinion interactions and lead to the formation of macroscopic opinion clusters. In addition, more topics accelerate the evolutionary process and weaken the effect of network topology. We use two sets of large-scale real data to evaluate the model, and the results prove its effectiveness in characterizing a real evolutionary process. Our model achieves high performance in individual action prediction and even outperforms state-of-the-art methods. Meanwhile, our model has much smaller computational complexity. This paper provides a demonstration for possible practical applications of theoretical opinion dynamics.

    This paper studies the opinion formation problem in a group of mobile agents using a multi-agent modeling method. Suppose that all agents move in a two-dimensional space following a certain rule. The interaction range of each agent is determined by its physical location and its opinion similarity with other agents. Moreover, agents have memory of the opinions of their previous interactive neighbors. We investigate the influence of three factors on the formation of group opinion: moving probability, interactive radius, and population density. Using simulations, we find that an opinion consensus can be achieved easily under a small moving probability and a small interactive radius, which is a relatively counterintuitive phenomenon. We also find that a large interactive radius or the model with memory can facilitate the convergence of opinions in a group to either consensus or clusters.

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

    International Nuclear Information System (INIS)

    Xiong, Fei; Liu, Yun; Zhang, Zhenjiang

    2014-01-01

    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 first document proposes a presentation of the project, an indication of dialogue and information actions, an overview of the impact study, a presentation of different implantation possibilities (7 or 3 turbines), an overview of site sensitivity and project impacts during different phases (construction, operation, dismantling). This encompasses impacts on the physical environment, on the natural environment, on the sound environment, and others (shade, night beacons, television reception), on forest exploitation and agriculture, on the economy, on tourism. Aeronautical and radio-electric constraints are discussed, as well as impact on safety, compliance with planning documents, impact on landscape and on heritage. Mitigating, compensating and supporting measures are described. A second document presents the official opinion of the Authority for the environment. It presents and discusses the project and its context, a discussion of the quality and comprehensiveness of information contained by the impact study and hazard study. A report of the public inquiry is then proposed which contains a presentation of file content, a description of the inquiry organisation and procedure, a comment on public remarks. A last document proposes maps and photomontages which give an idea of what landscape will look like with implanted wind turbines

    Research in recent decades has identified the varied information needs of engineers versus scientists. While most of that research looked at the differences among organizations, we surveyed engineers and scientists within a single Air Force research and development laboratory about their information gathering, usage, and production practices. The results of the Phillips Laboratory survey confirm prior assumptions about distinctions between engineering and science. Because military employees responded at a much higher rate than civilian staff, the survey also became an opportunity to profile a little-known segment of the engineer/scientist population. In addition to the effect Phillips Laboratory's stated mission may have on member engineers and scientists, other factors causing variations in technical communication and information-related activities are identified.

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

    Science.gov (United States)

    Xiong, Fei; Liu, Yun; Zhang, Zhenjiang

    2014-12-01

    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.

Methodology/methods: The paper can be perceived as a replication in a loose sense of the term, since it replicates only a part of a previously published model...... and in one's own opinion (two variables). Generalized linear models (GLM) and Pearson product-moment correlation coefficient are used to analyze data. Scientific aim: The aim of the paper is to estimate impact of gender and personality traits on opinion leadership. Findings: Extraversion is the personality...... trait closest related to opinion leadership regardless whether it is self-perceived in the eyes of others or in one's own opinion. Opinion leadership in one's own opinion can be predicted even using neuroticism, and conscientiousness. The three traits are consistent with previous findings. Unlike...

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

  18. Expert opinion vs. empirical evidence

    Science.gov (United States)

    Herman, Rod A; Raybould, Alan

    2014-01-01

    Expert opinion is often sought by government regulatory agencies when there is insufficient empirical evidence to judge the safety implications of a course of action. However, it can be reckless to continue following expert opinion when a preponderance of evidence is amassed that conflicts with this opinion. Factual evidence should always trump opinion in prioritizing the information that is used to guide regulatory policy. Evidence-based medicine has seen a dramatic upturn in recent years spurred by examples where evidence indicated that certain treatments recommended by expert opinions increased death rates. We suggest that scientific evidence should also take priority over expert opinion in the regulation of genetically modified crops (GM). Examples of regulatory data requirements that are not justified based on the mass of evidence are described, and it is suggested that expertise in risk assessment should guide evidence-based regulation of GM crops.

  12. An opinion formation based binary optimization approach for feature selection

    Science.gov (United States)

    Hamedmoghadam, Homayoun; Jalili, Mahdi; Yu, Xinghuo

    2018-02-01

    This paper proposed a novel optimization method based on opinion formation in complex network systems. The proposed optimization technique mimics human-human interaction mechanism based on a mathematical model derived from social sciences. Our method encodes a subset of selected features to the opinion of an artificial agent and simulates the opinion formation process among a population of agents to solve the feature selection problem. The agents interact using an underlying interaction network structure and get into consensus in their opinions, while finding better solutions to the problem. A number of mechanisms are employed to avoid getting trapped in local minima. We compare the performance of the proposed method with a number of classical population-based optimization methods and a state-of-the-art opinion formation based method. Our experiments on a number of high dimensional datasets reveal outperformance of the proposed algorithm over others.

    This report covers the Task 4 activities for the Sealed Source and Device Safety testing program. SwRI was contracted to investigate a suspected leaking radioactive source that was installed in a gauge that was on a paper mill digester. The actual source that was leaking was not available, therefore, SwRI examined another source. SwRI concluded that the encapsulated source examined by SwRI was not leaking. However, the presence of Cs-137 on the interior and exterior of the outer encapsulation and hending tube suggests that contamination probably occurred when the source was first manufactured, then installed in the handling tube

    In magnetic fusion plasmas, a significant fraction of the kinetic pressure is contributed by superthermal charged particles produced by auxiliary heating (fast ions and electrons) and fusion reactions (a-particles). Since these energetic particles are often far away from thermal equilibrium due to their non-Maxwellian distribution and steep pressure gradients, the free energy can excite electromagnetic instabilities to intensity levels well above the thermal fluctuations. The resultant electromagnetic turbulence could induce large transport of energetic particles, which could reduce heating efficiency, degrade overall plasma confinement, and damage fusion devices. Therefore, understanding and predicting energetic particle confinement properties are critical to the success of burning plasma experiments such as ITER since the ignition relies on plasma self-heating by a-particles. To promote international exchanges and collaborations on energetic particle physics, the biannual conference series under the auspices of the International Atomic Energy Agency (IAEA) were help in Kyiv (1989), Aspenas (1991), Trieste (1993), Princeton (1995), JET/Abingdon (1997), Naka (1999), Gothenburg (2001), San Diego (2003), Takayama (2005), Kloster Seeon (2007), Kyiv (2009), and Austin (2011). The papers in this special section were presented at the most recent meeting, the 13th IAEA Technical Meeting on Energetic Particles in Magnetic Confinement Systems, which was hosted by the Fusion Simulation Center, Peking University, Beijing, China (17-20 September 2013). The program of the meeting consisted of 71 presentations, including 13 invited talks, 26 oral contributed talks, 30 posters, and 2 summary talks, which were selected by the International Advisory Committee (IAC).

    In this paper, we present a prototype system called MindDigger, which can be used to analyze the opinions in Chinese movie reviews. Different from previous research that employed techniques on product reviews, we focus on Chinese movie reviews, in which opinions are expressed in subtle and varied ways. The system designed in this work aims to extract the opinion expressions and assign them to the corresponding features. The core tasks include feature and opinion extraction, and feature-opinion association. To deal with Chinese effectively, several novel approaches based on syntactic analysis are proposed in this paper. Running results show the performance is satisfactory.

  18. Opinion dynamics with confirmation bias.

    Directory of Open Access Journals (Sweden)

    Armen E Allahverdyan

    Full Text Available 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.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 preference is given to the last opinion (recency or the first opinion (primacy -and relates recency to confirmation bias. Finally, we study the model in the case of repeated persuasion and analyze its convergence properties.The standard Bayesian approach to probabilistic opinion revision is inadequate for describing the observed phenomenology of persuasion process. The simple non-Bayesian model proposed here does agree with this phenomenology and is capable of reproducing a spectrum of effects observed in psychology: primacy-recency phenomenon, boomerang effect and cognitive dissonance. We point out several limitations of the model that should motivate its future development.

According to this line of thought voters are more likely to accept information that con_rms their opinion compared to information that contradict their point of view.

    Aiming at the weight of trust someone given to participate in the interaction in Hegselmann-Krause's type consensus model is the same and virtual social networks among individuals with different level of education, personal influence, etc. For differences between agents, a novelty bounded confidence model was proposed with leader's opinion considered priority. Interaction neighbors can be divided into two kinds. The first kind is made up of "opinion leaders" group, another kind is made up of ordinary people. For different groups to give different weights of trust. We also analyzed the related characteristics of the new model under the symmetrical bounded confidence parameters and combined with the classical HK model were analyzed. Simulation experiment results show that no matter the network size and initial view is subject to uniform distribution or discrete distribution. We can control the "opinion-leader" good change the number of views and values, and even improve the convergence speed. Experiment also found that the choice of "opinion leaders" is not the more the better, the model well explain how the "opinion leader" in the process of the evolution of the public opinion play the role of the leader.

  2. Reproducible research: a minority opinion

    Science.gov (United States)

    Drummond, Chris

    2018-01-01

    Reproducible research, a growing movement within many scientific fields, including machine learning, would require the code, used to generate the experimental results, be published along with any paper. Probably the most compelling argument for this is that it is simply following good scientific practice, established over the years by the greats of science. The implication is that failure to follow such a practice is unscientific, not a label any machine learning researchers would like to carry. It is further claimed that misconduct is causing a growing crisis of confidence in science. That, without this practice being enforced, science would inevitably fall into disrepute. This viewpoint is becoming ubiquitous but here I offer a differing opinion. I argue that far from being central to science, what is being promulgated is a narrow interpretation of how science works. I contend that the consequences are somewhat overstated. I would also contend that the effort necessary to meet the movement's aims, and the general attitude it engenders would not serve well any of the research disciplines, including our own.

    one of the three most important problems. The disadvantages of nuclear power mentioned by 28 percent of the population centre on the issue of pollution - without specifying the type of pollution - and 35 percent refer to the risk of radioactive releases. The information and communication work carried out by the nuclear industry since the country's first nuclear power plant went on line in 1968 has had obvious positive effects on public opinion in the areas surrounding the plants. Comparison of the replies provided by the general population and those from interviewees forming part of populations living close to nuclear power plants clearly demonstrates that opinions are directly related to the greater or lesser degree of ignorance of the subject. Knowledge of the location of Spain's nuclear power plants provides equally curious results. Seventy-five percent of the population claims to know that there are nuclear plants in Spain, but twenty-eight percent does not know or does not answer where these installations are. Evaluation of the data obtained allows the following conclusions to be drawn: Only 8 percent of the interviewees claims to be, pro-nuclear, i.e. in favour of new nuclear power plants being built if there were a need to extend the current generating capacity; 20 percent of the population respects the assumptions made in the Spanish nuclear moratorium: they consider that the plants currently in operation should not be closed down, and that no new plants should be built; 19 percent, thinks that the current plants should be closed, in spite of their recognizing that these installations are necessary and contribute to electricity generation; 24 percent is in favour of gradually replacing the nuclear power plants with other energy sources; 29 percent thinks that the currently operating plants should be shut down. This includes two percent of the population that openly claim to be actively antinuclear in their approach. The future of the Spanish nuclear industry

    Social interaction between individuals constantly affects the development of their personal opinions. Previous models such as the Deffuant model and the Hegselmann-Krause (HK) model have assumed that individuals only update their opinions after interacting with neighbors whose opinions are similar to their own. However, people are capable of communicating widely with all of their neighbors to gather their ideas and opinions, even if they encounter a number of opposing attitudes. We propose a model in which agents listen to the opinions of all their neighbors. Continuous opinion dynamics are investigated in activity-driven networks with a tolerance threshold. We study how the initial opinion distribution, tolerance threshold, opinion-updating speed, and activity rate affect the evolution of opinion. We find that when the initial fraction of positive opinion is small, all opinions become negative by the end of the simulation. As the initial fraction of positive opinions rises above a certain value —about 0.45— the final fraction of positive opinions sharply increases and eventually equals 1. Increased tolerance threshold δ is found to lead to a more varied final opinion distribution. We also find that if the negative opinion has an initial advantage, the final fraction of negative opinion increases and reaches its peak as the updating speed λ approaches 0.5. Finally we show that the lower the activity rate of individuals, the greater the fluctuation range of their opinions.

    In this paper, we investigate processes associated with formation of public opinion in varies directed random, scale free and small-world social networks. The important factor of the opinion formation is the existence of contrarians which were discovered by Granovetter in various social psychology experiments1,2,3 long ago and later introduced in sociophysics by Galam.4 When the density of contrarians increases the system behavior drastically changes at some critical value. At high density of contrarians the system can never arrive to a consensus state and periodically oscillates with different periods depending on specific structure of the network. At small density of the contrarians the behavior is manifold. It depends primary on the initial state of the system. If initially the majority of the population agrees with each other a state of stable majority may be easily reached. However when originally the population is divided in nearly equal parts consensus can never be reached. We model the emergence of collective decision making by considering N interacting agents, whose opinions are described by two state Ising spin variable associated with YES and NO. We show that the dynamical behaviors are very sensitive not only to the density of the contrarians but also to the network topology. We find that a phase of social chaos may arise in various dynamical processes of opinion formation in many realistic models. We compare the prediction of the theory with data describing the dynamics of the average opinion of the USA population collected on a day-by-day basis by varies media sources during the last six month before the final Obama-McCain election. The qualitative ouctome is in reasonable agreement with the prediction of our theory. In fact, the analyses of these data made within the paradigm of our theory indicates that even in this campaign there were chaotic elements where the public opinion migrated in an unpredictable chaotic way. The existence of such a phase

    Paper-based microfluidic devices (μPADs) are capable of achieving rapid quantitative measurements of a variety of analytes inexpensively. μPADs rely on patterning hydrophilic-hydrophobic regions on a sheet of paper in order to create capillary channels within impermeable fluidic brakes on the paper. Here, we present a novel, highly flexible and low-cost fabrication method using a desktop digital craft plotter/cutter and technical drawing pens with tip size of 0.5 mm. The pens were used with either commercial black permanent ink for drawing fluidic brakes, or with specialty in-house formulated aqueous inks. With the permanent marker ink it was possible to create barriers on paper rapidly and in a variety of designs in a highly flexible manner. For instance, a design featuring eight reservoirs can be produced within 10 s for each μPAD with a consistent line width of brakes (%RSD drawing pens provides flexibility in the use of in-house formulated inks, short fabrication time, simplicity and low cost.

    In an expert opinion written by Professor H. Kuni, Marburg, for the North Rhine-Westphalian state government, plutonium is called by far the most dangerous element in the Periodic Table. The Marburg medical expert holds that even improved legal instruments are unable to warrant effective protection of the workers handling this material, in the light of the present standards of industrial safety, because of radiological conditions and measuring problems with plutonium isotopes. In this article by an internationally renowned expert in the field, the ideas expressed in the expert opinion about the toxicity of plutonium, the cause-and-effect relationship in radiation damage by plutonium, and recent findings about the toxicity are subjected to a critical review. On the basis of results of radiation protection and of case studies, the statements in the expert opinion are contrasted with facts which make them appear in a very different light. (orig./RB) [de

    The study of opinion dynamics, such as spreading and controlling of rumors, has become an important issue on social networks. Numerous models have been devised to describe this process, including epidemic models and spin models, which mainly focus on how opinions spread and interact with each other, respectively. In this paper, we propose a model that combines the spreading stage and the interaction stage for opinions to illustrate the process of dispelling a rumor. Moreover, we set up authoritative nodes, which disseminate positive opinion to counterbalance the negative opinion prevailing on online social networking sites. With analysis of the relationship among positive opinion proportion, opinion strength and the density of authoritative nodes in networks with different topologies, we demonstrate that the positive opinion proportion grows with the density of authoritative nodes until the positive opinion prevails in the entire network. In particular, the relationship is linear in homogeneous topologies. Besides, it is also noteworthy that initial locations of the negative opinion source and authoritative nodes do not influence positive opinion proportion in homogeneous networks but have a significant impact on heterogeneous networks. The results are verified by numerical simulations and are helpful to understand the mechanism of two different opinions interacting with each other on online social networking sites.

    The advent of global markets elevates the role and importance of culture as a mitigating factor in the diffusion of knowledge and technology and in product and process innovation. This is especially true in the Large Commercial Aircraft (LCA) sector where the production and market aspects are becoming increasingly international. As firms expand beyond their national borders, using such methods as risk- sharing partnerships, joint ventures, outsourcing, and alliances, they have to contend with national and corporate cultures. Our focus is on Japan, a 'program participant' in the production of the Boeing Company's 777; the influence of Japanese culture on the diffusion of knowledge and technology in aerospace at the national and international levels; those cultural determinants-the propensity to work together, a willingness to subsume individual interests to a greater good, and an emphasis on consensual decisionmaking-that have a direct bearing on the ability of Japanese firms to form alliances and compete in international markets; and those cultural determinants thought to influence the information- seeking behaviors and workplace communication practices of Japanese aerospace engineers and scientists. In this paper, we report selective results from a survey of Japanese and U.S. aerospace engineers and scientists that focused on workplace communications. Data are presented for the following topics: importance of and time spent communicating information, collaborative writing, need for an undergraduate course in technical communication, use of libraries, use and importance of electronic (computer) networks, and the use and importance of foreign and domestically produced technical reports.

    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

    Full Text Available Abraham Lincoln has never served as a model for French politicians. He was indeed compared to Carnot, the organizer of the French Revolutionary wars. But when Clemenceau led France in WWI, when De Gaulle stood for France’s independence in WWII, nobody thought of comparing them to Lincoln. This essay analyzes French public opinion during the American Civil War with a focus on Lincoln, based on a study of the few French books published between 1860 and 1865 on the US, diaries, a sample of conservative and republican daily papers, weekly reviews and illustrated newspapers.

    Policymakers often motivate their decisions using information collected by government agencies. While more information can help hold the government to account, it may also give policymakers an incentive to meddle with the work of bureaucrats. This paper develops a model of biased information...... information is always unbiased, may also not be socially optimal. A biased information-gathering process can benefit the government by helping it to shape public opinion. But it can also benefit the public, by curbing the government's tendency to implement its ex ante favored policy, thus mitigating...... the agency conflict between policymakers and the public....

As a result of the research, it was necessary to answer the following important questions: What are the objectives of the lecture and the role of the lecturer? Which lectures are more preferable: traditional or interactive? What do lecturers expect from the lecture, do they consider it an advantage or an unnecessary educational activity?The materials were developed for the survey (questionnaire to conduct the research and analyze the results obtained. The students were surveyed before training and after completion of the semester. The study involved 200 students of all areas of Mechanics and Technology Faculty of Novosibirsk State Technical University. Statistical analysis was used for the analysis of the results.As a result, the experiment revealed nonconformity of opinions of students about the purpose of the lecture and the role of a lecturer before the training and after the end of the semester. Lectures, according to students, should help to implement all kinds of practical and independent assignments.Educational standards imply a reduction in the hours of classroom training and an increase in independent work, and the majority of students are not ready (do not want to to study the materials on the topics of discipline completely independently or partially.It revealed a contradiction in opinion, what form of organization of the lecture classes is more interesting to students, which can increase the motivation of the visit and work on the lectures.The technology of designing the educational process in the conditions of the mixed training is proposed, applying the technological map.The technological map is presented in the form of stages of designing the educational process, including recommendations on the use of

    Future developments in the attitude towards nuclear energy can not be predicted on account of this public opinion survey. The survey shows just how many different factors influence the attitude towards issues of public and political interst. For this reason in particular, it would be desirable to include such aspects into future surveys. The survey shows that public opinion polls quite often investigate on the ordering party's opinion rather than the pollees opinion. The attempt at making public opinion polls a means of forming political opinions, implying a certain desired opinion to be the majority opinion has brought those polls into disrepute. If real results are not required and manipulation prevails, results are prevented, which must not be blamed on the principle of public opinion polls as such. (orig.) [de

    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 intention is pointed at the public opinion. The public debate, linked to the political system, is described in the frame where the opinions are expressed in interaction with the media. This debate has a fundamental role in the opinions structuration. Then it is shown how it is possible to introduce it in the way of measuring the opinions. Then, we arrive to the structures of public opinion. The analysis of facts registered during twenty years on nuclear energy allows to illustrate the interest of this global approach: considered from a controversy point of view, it is also a technical object and then it can be considered as a differentiation theme among others ones.

    The inner dynamics of the multiple actors of the informations systems - i.e, T.V., newspapers, blogs, social network platforms, - play a fundamental role on the evolution of the public opinion. Coherently with the recent history of the information system (from few main stream media to the massive diffusion of socio-technical system), in this work we investigate how main stream media signed interaction might shape the opinion space. In particular we focus on how different size (in the number of media) and interaction patterns of the information system may affect collective debates and thus the opinions' distribution. We introduce a sophisticated computational model of opinion dynamics which accounts for the coexistence of media and gossip as separated mechanisms and for their feedback loops. The model accounts also for the effect of the media communication patterns by considering both the simple case where each medium mimics the behavior of the most successful one (to maximize the audience) and the case where there is polarization and thus competition among media memes. We show that plurality and competition within information sources lead to stable configurations where several and distant cultures coexist.

    Full Text Available Understanding and quantifying polarization in social systems is important because of many reasons. It could for instance help to avoid segregation and conflicts in the society or to control polarized debates and predict their outcomes. In this paper, we present a version of the q-voter model of opinion dynamics with two types of responses to social influence: conformity (like in the original q-voter model and anticonformity. We put the model on a social network with the double-clique topology in order to check how the interplay between those responses impacts the opinion dynamics in a population divided into two antagonistic segments. The model is analyzed analytically, numerically and by means of Monte Carlo simulations. Our results show that the system undergoes two bifurcations as the number of cross-links between cliques changes. Below the first critical point, consensus in the entire system is possible. Thus, two antagonistic cliques may share the same opinion only if they are loosely connected. Above that point, the system ends up in a polarized state.

    Highlights: •We use Dempster–Shafer evidence theory to handle the uncertainty of the communication. •An ice-breaking uncertainty elimination process in opinion evolution is demonstrated. •The influential power of individuals and the feedback mechanism are considered. •The power-law characteristic of the final influential power distribution is depicted. -- Abstract: This paper introduces an evidential opinion dynamics model combing Dempster–Shafer evidence theory to explore the opinion evolution. Our model is an improvement of the Continuous Opinions and Discrete Actions (CODA) model. The process of people updating their opinions is regarded as a decision making process. The unavoidable uncertainty of the opinion evolution is handled by Dempster–Shafer evidence theory. Thereby, a new opinion group, i.e.the neutrals, is introduced into the system. Simulations show the neutral group plays a significant part in the opinion evolution. An opinion ice-breaking process at the early stage of the opinion evolution is observed. It is found that the consensus is not always reached then clusters emerge instead, which depends on the proportions of supporters, neutrals and opponents. The individual’s influential power is taken into account. With the positive feedback mechanism of people’s influential power, the obtained results are in accordance with people’s daily cognition such as the Authority Effect and the Matthew Effect. The final influential power distribution of all individuals in our model presents power-law characteristic

    Full Text Available In recent years, the spectacular development of web technologies, lead to an enormous quantity of user generated information in online systems. This large amount of information on web platforms make them viable for use as data sources, in applications based on opinion mining and sentiment analysis. The paper proposes an algorithm for detecting sentiments on movie user reviews, based on naive Bayes classifier. We make an analysis of the opinion mining domain, techniques used in sentiment analysis and its applicability. We implemented the proposed algorithm and we tested its performance, and suggested directions of development.

    Paper is ubiquitous in everyday life and a truly low-cost substrate. The use of paper substrates could be extended even further, if electronic applications would be applied next to or below the printed graphics. However, applying electronics on paper is challenging. The paper surface is not only very rough compared to plastics, but is also porous. While this is detrimental for most electronic devices manufactured directly onto paper substrates, there are also approaches that are compatible with the rough and absorptive paper surface. In this review, recent advances and possibilities of these approaches are evaluated and the limitations of paper electronics are discussed. Copyright © 2011 WILEY-VCH Verlag GmbH & Co.

    With the rapid development of mobile Internet, user gradually become the leader of social media, the abruptly rise of new media has changed the traditional information's dissemination pattern and regularity. There is new era significance of opinion leaders, gatekeepers in the classical theory of mass communication, and it has further expansion and extension to a certain extent. In the existing mining of opinion leaders, it is mainly from the research of network structure and user behavior without considering an important attribute: whether the user has a real impact. In this paper, we take the symbolic network as the research tool, by giving symbol which correspondingly represents support or oppose to the link about point of view relationship between users and combining traditional algorithms of mining with symbolism which can describe the change of view between users, we will get the opinion leader who has real impact on users, then the result is more accurate and effective.

    2003-01-01

    Nuclear Training Centre Milan Copic at Jozef Stefan Institute in Ljubljana is performing extensive public information activities, focused mainly on elementary and high schools in Slovenia. There are over 7000 visitors yearly. Every year in the spring we ask several hundred of visitors the same set of questions about their knowledge and opinion about nuclear energy. They are polled before they listen to the lecture or visit the exhibition. In that way we are trying to obtain their opinion based on the knowledge they obtain in everyday life. In the paper the results of this year's poll are presented and compared with the previous years. No significant changes in public opinion were observed this year. Favourable attitude towards NPP Krsko, which could be observed in the last years, is maintained. On the other hand, misconceptions about radioactive waste repositories and danger of radioactive waste remain very high. (author)

  17. The Distribution of Climate Change Public Opinion in Canada.

    Directory of Open Access Journals (Sweden)

    Matto Mildenberger

    Full Text Available While climate scientists have developed high resolution data sets on the distribution of climate risks, we still lack comparable data on the local distribution of public climate change opinions. This paper provides the first effort to estimate local climate and energy opinion variability outside the United States. Using a multi-level regression and post-stratification (MRP approach, we estimate opinion in federal electoral districts and provinces. We demonstrate that a majority of the Canadian public consistently believes that climate change is happening. Belief in climate change's causes varies geographically, with more people attributing it to human activity in urban as opposed to rural areas. Most prominently, we find majority support for carbon cap and trade policy in every province and district. By contrast, support for carbon taxation is more heterogeneous. Compared to the distribution of US climate opinions, Canadians believe climate change is happening at higher levels. This new opinion data set will support climate policy analysis and climate policy decision making at national, provincial and local levels.

    Highlights: • We study a simple model of persuasion dynamics with long range pairwise interactions. • The continuous limit of the master equation is a nonlinear, nonlocal, first order partial differential equation. • We compute the analytical solutions to this equation, and compare them with the simulations of the dynamics. - Abstract: Frequently we revise our first opinions after talking over with other individuals because we get convinced. Argumentation is a verbal and social process aimed at convincing. It includes conversation and persuasion and the agreement is reached because the new arguments are incorporated. Given the wide range of opinion formation mathematical approaches, there are however no models of opinion dynamics with nonlocal pair interactions analytically solvable. In this paper we present a novel analytical framework developed to solve the master equations with non-local kernels. For this we used a simple model of opinion formation where individuals tend to get more similar after each interactions, no matter their opinion differences, giving rise to nonlinear differential master equation with non-local terms. Simulation results show an excellent agreement with results obtained by the theoretical estimation.

    1981-01-01

    Two terms, two job categories, 'technical writer' and 'technical author' are discussed in terms of industrial and business requirements and standards. A distinction between 'technical writing' and technical 'writing' is made. The term 'technical editor' is also considered. Problems inherent in the design of programs to prepare and train students for these jobs are discussed. A closer alliance between industry and academia is suggested as a means of preparing students with competent technical communication skills (especially writing and editing skills) and good technical skills.

    1989-01-01

    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

    Until the recent dissolution of the Soviet Union, the Communist Party exerted a strict control of access to and dissemination of scientific and technical information (STI). This article presents models of the Soviet-style information society and the Western-style information society and discusses the effects of centralized governmental control of information on Russian technical communication practices. The effects of political control on technical communication are then used to interpret the results of a survey of Russian and U.S. aerospace engineers and scientists concerning the time devoted to technical communication, their collaborative writing practices and their attitudes toward collaboration, the kinds of technical documents they produce and use, and their use of computer technology, and their use of and the importance to them of libraries and technical information centers. The data are discussed in terms of tentative conclusions drawn from the literature. Finally, we conclude with four questions concerning government policy, collaboration, and the flow of STI between Russian and U.S. aerospace engineers and scientists.

  7. French opinion on Nuclear Energy

    2003-01-01

    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

    The public opinion on Nuclear Power is not favorable. A purposeful work with public perception is necessary. One way to create a positive image of the nuclear industry is to improve public radiological education. This challenge can be resolved in the close cooperation with state school and preschool education. The formation about nuclear power should be simple and symbolical. Our society can be divided into 4 parts which can be called as target groups: First group - People from the nuclear industry with special education working at nuclear facilities or related to the industry. Second group - People working in the fields connected with nuclear power. Third group - People not related to nuclear power or even with negative impression to the industry. This group is the largest and the work required is the most difficult. Fourth group - The number of this group's members is the least, but it has strong influence on public opinion. 'Greens' and a broad spectrum of ecological organizations can be included in this group. (Authors)

    Full Text Available The transposition of the São Francisco River is considered one of the greatest engineering works in Brazil of all time since it will cross an extensive agricultural region of continental dimensions, involving environmental impacts, water, soil, irrigation, water payment and other multidisciplinary themes. Taking into account its importance, this subject was incorporated into a discipline of UFSCar (Federal University of São Carlos - Brazil named "Pollution and Environmental Impacts". It was noted strong reaction against the project, even before the presentation. To allow a critical analysis, the first objective was to compile the main technical data and environmental impacts. The second objective was to detect the three most important aspects that cause reaction, concluding for the following reasons: assumption that the volume of water to be transferred was much greater than it actually is proposed in the project; lack of knowledge about similar project already done in Brazil; the idea that the artificial canal to be built was much broader than that proposed by the project. The participants' opinion about "volume to be transferred" was raised quantitatively four times: 2-undergraduate students; 1-graduate; 1-outside community. The average resulted 14 times larger than that proposed in the project, significant according to t-test. It was concluded that the reaction to water transfer project is due in part to the ignorance combined with a preconceived idea that tend to overestimate the magnitude of environmental impacts.A transposição do Rio São Francisco, uma das maiores obras de engenharia do Brasil de todos os tempos, cortará uma extensa região agrícola de dimensões continentais, envolvendo temas de caráter multidisciplinar, como impactos ambientais, água, solo, irrigação, outorga de água e outros.

  10. Energy policy decision making and public opinion

    Gerstein, L.

    1989-09-01

    By the example of nuclear the author demonstrates the interactions of short-term fluctuations on the world energy market, energy forecasts, specific events and discussions on energy policy both within political parties and in the general public, and draws conclusions which are valid beyond the Federal Republic of Germany: An analysis of the general public's attitude towards nuclear energy shows two initial phases, i.e. euphoria and scepticism/ideology/agitation. The early eighties, then, led to a third phase - realism. Up to 1983 a consensus prevailed between the leading political parties in Germany regarding the basic energy-policy objective of minimizing the supply risk by providing for a well-balanced use of all available energy sources. The resulting attitude had a positive bearing on the public opinion: more than two thirds of the population were in favour of nuclear. In the mid-eighties, the development of nuclear was by and large completed in the Federal Republic of Germany as well as in the United States and other western industrialized countries and the capacity of nuclear power plants is considered sufficient for the years to come. In addition, abundant long-term reserves of domestic lignite and hardcoal are available: this also should have furnished a good reason to envisage calmly the issues of power supply. Instead, we are again facing emotional discussions on the acceptance of nuclear. Public opinion in the Federal Republic of Germany has changed since the Social Democrats followed the example of the Ecologists and advocated a rapid withdrawal from nuclear. In a recent poll four-fifths of the persons asked did not rule out the possibility of a major accident in a German power station. The wish to ignore today's energy supply problems by escaping into a supposedly safe but yet distant and vague future is part of every public debate. Technical and scientific issues are examined no longer in this global context. Predictions of experts and counter

    The results of a public opinion survey on energy, conducted by Prime Minister's Office from November 26 to December 2, 1980, are described. Of the sampling of 5,000 adults throughout the nation, 4,113 replied the questions. The contents are as follows: awaraness of energy conservation, projection of the future of nuclear power, uneasiness about nuclear power, and energy policies. Concerning the major power generation system of the future, 47% of the people mentioned nuclear energy, followed by 18% mentioned solar energy. As to the future share of nuclear power, 38% favored its increase, 28% its maintaining at the current level, and only 5% wanted its decrease. About the feeling of uneasiness, 56% felt uneasiness and 44% were secure, making it clear that the uneasiness has not yet been eliminated. (J.P.N.)

    Multilayer and multiplex networks represent a good proxy for the description of social phenomena where social structure is important and can have different origins. Here, we propose a model of opinion competition where individuals are organized according to two different structures in two layers. Agents exchange opinions according to the Abrams-Strogatz model in each layer separately and opinions can be copied across layers by the same individual. In each layer a different opinion is dominant, so each layer has a different absorbing state. Consensus in one opinion is not the only possible stable solution because of the interaction between the two layers. A new mean field solution has been found where both opinions coexist. In a finite system there is a long transient time for the dynamical coexistence of both opinions. However, the system ends in a consensus state due to finite size effects. We analyze sparse topologies in the two layers and the existence of positive correlations between them, which enables the coexistence of inter-layer groups of agents sharing the same opinion.

    Opinion competition is a common phenomenon in real life, such as with opinions on controversial issues or political candidates; however, modelling this competition remains largely unexplored. To bridge this gap, we propose a model of competing opinion diffusion on social networks taking into account degree-dependent fitness or persuasiveness. We study the combined influence of social networks, individual fitnesses and attributes, as well as mass media on people's opinions, and find that both social networks and mass media act as amplifiers in opinion diffusion, the amplifying effect of which can be quantitatively characterized. We analytically obtain the probability that each opinion will ultimately pervade the whole society when there are no committed people in networks, and the final proportion of each opinion at the steady state when there are committed people in networks. The results of numerical simulations show good agreement with those obtained through an analytical approach. This study provides insight into the collective influence of individual attributes, local social networks and global media on opinion diffusion, and contributes to a comprehensive understanding of competing diffusion behaviours in the real world.

    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.

    Full Text Available In this paper we demonstrate approaches for opinion mining in Latvian text. Authors have applied, combined and extended results of several previous studies and public resources to perform opinion mining in Latvian text using two approaches, namely, semantic polarity analysis and machine learning. One of the most significant constraints that make application of opinion mining for written content classification in Latvian text challenging is the limited publicly available text corpora for classifier training. We have joined several sources and created a publically available extended lexicon. Our results are comparable to or outperform current achievements in opinion mining in Latvian. Experiments show that lexicon-based methods provide more accurate opinion mining than the application of Naive Bayes machine learning classifier on Latvian tweets. Methods used during this study could be further extended using human annotators, unsupervised machine learning and bootstrapping to create larger corpora of classified text.

    Elgot, Calvin C

    1982-01-01

    Cal Elgot was a very serious and thoughtful researcher, who with great determi­ nation attempted to find basic explanations for certain mathematical phenomena­ as the selection of papers in this volume well illustrate. His approach was, for the most part, rather finitist and constructivist, and he was inevitably drawn to studies of the process of computation. It seems to me that his early work on decision problems relating automata and logic, starting with his thesis under Roger Lyndon and continuing with joint work with Biichi, Wright, Copi, Rutledge, Mezei, and then later with Rabin, set the stage for his attack on the theory of computation through the abstract treatment of the notion of a machine. This is also apparent in his joint work with A. Robinson reproduced here and in his joint papers with John Shepherdson. Of course in the light of subsequent work on decision problems by Biichi, Rabin, Shelah, and many, many others, the subject has been placed on a completely different plane from what it was whe...

    Traditional public opinion polls are surveys in which a random sample of a given population is asked questions about their attitudes, knowledge, or behavior. If conducted properly, the answers from such surveys are approximately representative of the entire population. Traditional public opinion...... polling is typically based on four different methods of data gathering, or combinations hereof: face-to-face, postal surveys, phone surveys, and web surveys. Given that opinion polls are based on a sample, we cannot be sure that the sample reflects public opinion perfectly, however—even if randomness...... is perfect. Moreover, responses may be highly dependent on the contextual information provided with the question. Also, it may be difficult to capture past or complex causes of attitudes or behavior. In short, surveys are a precise way of measuring public opinion, but they do not come without challenges....

  15. Opinion formation models on a gradient.

    Directory of Open Access Journals (Sweden)

    Michael T Gastner

    Full Text Available Statistical physicists have become interested in models of collective social behavior such as opinion formation, where individuals change their inherently preferred opinion if their friends disagree. Real preferences often depend on regional cultural differences, which we model here as a spatial gradient g in the initial opinion. The gradient does not only add reality to the model. It can also reveal that opinion clusters in two dimensions are typically in the standard (i.e., independent percolation universality class, thus settling a recent controversy about a non-consensus model. However, using analytical and numerical tools, we also present a model where the width of the transition between opinions scales proportional g(-1/4, not proportional g(-4/7 as in independent percolation, and the cluster size distribution is consistent with first-order percolation.

  16. Nursing opinion leadership: a preliminary model derived from philosophic theories of rational belief.

    2013-10-01

    Opinion leaders are informal leaders who have the ability to influence others' decisions about adopting new products, practices or ideas. In the healthcare setting, the importance of translating new research evidence into practice has led to interest in understanding how opinion leaders could be used to speed this process. Despite continued interest, gaps in understanding opinion leadership remain. Agent-based models are computer models that have proven to be useful for representing dynamic and contextual phenomena such as opinion leadership. The purpose of this paper is to describe the work conducted in preparation for the development of an agent-based model of nursing opinion leadership. The aim of this phase of the model development project was to clarify basic assumptions about opinions, the individual attributes of opinion leaders and characteristics of the context in which they are effective. The process used to clarify these assumptions was the construction of a preliminary nursing opinion leader model, derived from philosophical theories about belief formation. © 2013 John Wiley & Sons Ltd.

    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

    To design and maintain its education program, the United States Department of Energy (DOE) Hydrogen Program conducted a statistically-valid national survey to measure knowledge and opinions of hydrogen among key target audiences. The Hydrogen Baseline Knowledge Survey provides a reference for designing the DOE hydrogen education strategy and will be used in comparisons with future surveys to measure changes in knowledge and opinions over time. The survey sampled four U.S. populations: (1) public; (2) students; (3) state and local government officials; and (4) potential large-scale hydrogen end-users in three business categories. Questions measured technical understanding of hydrogen and opinions about hydrogen safety. Other questions assessed visions of the likelihood of future hydrogen applications and sources of energy information. Several important findings were discovered, including a striking lack of technical understanding across all survey groups, as well as a strong correlation between technical knowledge and opinions about safety: those who demonstrated an understanding of hydrogen technologies expressed the least fear of its safe use.

    Because food and poultry industries are demanding an improvement in written communication skills among graduates, research paper writing should be an integral part of a senior undergraduate class. However, scientific writing assignments are often treated as secondary to developing the technical skills of the students. Scientific research paper writing has been emphasized in an undergraduate course on advanced food microbiology taught in the Poultry Science Department at Texas A& M University (College Station, TX). Students' opinions suggest that research paper writing as part of a senior course in Poultry Science provides students with scientific communication skills and useful training for their career, but more emphasis on reading and understanding scientific literature may be required.

  3. Choice Shift in Opinion Network Dynamics

    Science.gov (United States)

    Gabbay, Michael

    Choice shift is a phenomenon associated with small group dynamics whereby group discussion causes group members to shift their opinions in a more extreme direction so that the mean post-discussion opinion exceeds the mean pre-discussion opinion. Also known as group polarization, choice shift is a robust experimental phenomenon and has been well-studied within social psychology. In opinion network models, shifts toward extremism are typically produced by the presence of stubborn agents at the extremes of the opinion axis, whose opinions are much more resistant to change than moderate agents. However, we present a model in which choice shift can arise without the assumption of stubborn agents; the model evolves member opinions and uncertainties using coupled nonlinear differential equations. In addition, we briefly describe the results of a recent experiment conducted involving online group discussion concerning the outcome of National Football League games are described. The model predictions concerning the effects of network structure, disagreement level, and team choice (favorite or underdog) are in accord with the experimental results. This research was funded by the Office of Naval Research and the Defense Threat Reduction Agency.

    Paper is a material known to everybody. It has a network structure consisting of wood fibres that can be mimicked by cooking a portion of spaghetti and pouring it on a plate, to form a planar assembly of fibres that lie roughly horizontal. Real paper also contains other constituents added for technical purposes. This review has two main lines of thought. First, in the introductory part, we consider the physics that one encounters when 'using' paper, an everyday material that exhibits the presence of disorder. Questions arise, for instance, as to why some papers are opaque and others translucent, some are sturdy and others sloppy, some readily absorb drops of liquid while others resist the penetration of water. The mechanical and rheological properties of paper and paperboard are also interesting. They are inherently dependent on moisture content. In humid conditions paper is ductile and soft, in dry conditions brittle and hard. In the second part we explain in more detail research problems concerned with paper. We start with paper structure. Paper is made by dewatering a suspension of fibres starting from very low content of solids. The processes of aggregation, sedimentation and clustering are familiar from statistical mechanics. Statistical growth models or packing models can simulate paper formation well and teach a lot about its structure. The second research area that we consider is the elastic and viscoelastic properties and fracture of paper and paperboard. This has traditionally been the strongest area of paper physics. There are many similarities to, but also important differences from, composite materials. Paper has proved to be convenient test material for new theories in statistical fracture mechanics. Polymer physics and memory effects are encountered when studying creep and stress relaxation in paper. Water is a 'softener' of paper. In humid conditions, the creep rate of paper is much higher than in dry conditions. The third among our topics is the

  9. Nuclear power and public opinion

    Energy Technology Data Exchange (ETDEWEB)

    1984-01-01

    The diversity of factors involved in nuclear power development and the complexity of public attitudes towards this source of energy have raised the nuclear debate to a topic of national significance in all the OECD countries with nuclear programmes and even in some countries which have not embarked on the nuclear course. This study examines the different experiences of seventeen member countries and underlines basic approaches and practices aimed at winning greater public acceptance for nuclear power. The first part of the study is a country-by-country presentation of public acceptance activities and the role of the various public or private bodies involved. There is also a description of the background energy situation and the place of nuclear power, the evolution of the nuclear debate and a review of present public and political attitudes to nuclear energy. In the second part, some of the notable factors which determine public attitudes to, and perception of, nuclear energy have been assembled. The study points, in particular, to a number of general principles which require continuous implementation, not least because they contribute to placing nuclear energy in its proper context for the public. Vigorous government leadership in making energy choices, long term efforts in energy education, and open information policies can go a long way towards resolving many doubts about nuclear energy in the public mind. But, perhaps, above all, it is the continuing demonstration of the safe and efficient industrial operation of plants in the nuclear fuel cycle which will have the strongest influence on public opinion. In addition to these basic principles, the study calls attention to some of the most successful means of improving communication between the authorities and the public, notably at the local level. The contribution to the decision-making process of public participation is also evaluated in the light of recent national experiences.

    For telemedicine to realize the vision of anywhere, anytime access to care, the question of how to create a fully interoperable technical infrastructure must be addressed. After briefly discussing how 'technical interoperability' compares with other types of interoperability being addressed in the telemedicine community today, this paper describes reasons for pursuing technical interoperability, presents a proposed framework for realizing technical interoperability, identifies key issues that will need to be addressed if technical interoperability is to be achieved, and suggests a course of action that the telemedicine community might follow to accomplish this goal.

  13. Understanding Public Opinions from Geosocial Media

    Directory of Open Access Journals (Sweden)

    2016-05-01

    Full Text Available Increasingly, social media data are linked to locations through embedded GPS coordinates. Many local governments are showing interest in the potential to repurpose these firsthand geo-data to gauge spatial and temporal dynamics of public opinions in ways that complement information collected through traditional public engagement methods. Using these geosocial data is not without challenges since they are usually unstructured, vary in quality, and often require considerable effort to extract information that is relevant to local governments’ needs from large data volumes. Understanding local relevance requires development of both data processing methods and their use in empirical studies. This paper addresses this latter need through a case study that demonstrates how spatially-referenced Twitter data can shed light on citizens’ transportation and planning concerns. A web-based toolkit that integrates text processing methods is used to model Twitter data collected for the Region of Waterloo (Ontario, Canada between March 2014 and July 2015 and assess citizens’ concerns related to the planning and construction of a new light rail transit line. The study suggests that geosocial media can help identify geographies of public perceptions concerning public facilities and services and have potential to complement other methods of gauging public sentiment.

  14. Opinion poll tests support for democratic initiatives

    Burkhart, L.A.

    1993-01-01

    A national opinion poll designed to test public support for a position paper on energy policy for the Clinton Administration and the new Congress, was released February 9 at a Capitol Hill press conference sponsored by the Environmental and Energy Study Institute. The poll, conducted by the Democratic polling firm Greenberg/Lake and Republican pollster Lance Tarrance, found voters want energy efficiency, conservation, and renewable energy as top priorities for the nation's energy policy. It also found voters are willing to seek these policies with tough regulation, tax incentives, and their own behavior. Also, voters appear to support taxes on pollution and energy use, whether the income is used to decrease taxes on personal income, or to reduce the deficit. However, voters oppose gas taxes and are divided on taxes for fossil fuels. Support for energy taxes increases if revenues generated by them are dedicated to deficit reduction. The poll also revealed: the public's desire for less emphasis on polluting sources of energy such as oil and coal; low levels of support for nuclear power; support for government initiatives to increase the fuel efficiency of consumer goods such as appliances and automobiles; opposition to a substantial increase in the gasoline tax; and support for green taxes on polluting sources of energy use at the same time policy makers remove federal tax subsidies on fuels that pollute

    2013-02-01

    In this paper we investigate the effects of social power on the evolution of opinions in model networks as well as in a number of real social networks. A continuous opinion formation model is considered and the analysis is performed through numerical simulation. Social power is given to a proportion of agents selected either randomly or based on their degrees. As artificial network structures, we consider scale-free networks constructed through preferential attachment and Watts-Strogatz networks. Numerical simulations show that scale-free networks with degree-based social power on the hub nodes have an optimal case where the largest number of the nodes reaches a consensus. However, given power to a random selection of nodes could not improve consensus properties. Introducing social power in Watts-Strogatz networks could not significantly change the consensus profile.

    Full Text Available Firms should manage their customer feedback so they can adapt to rapid changes in the environment. They have to interact with their customers to understand them and to turn their opinions into useful knowledge. Understanding customers' feelings about a product gives firmS competitive advantage through continuous market monitoring. They can thus generate improving strategies about the system to change perceptions that drive the behaviours of the customers. Firms can view their customers' happiness as a key tool for decision-making. This study calculates online product happiness by using the average emotional valence values of customer opinions. We analyse Turkish opinions about a product over a period of 3 months. We find the averages of the online emotional valence values of the product per month. We also determined the increase in happiness over time. According to the opinion valence values, we found the relations between the documents.

    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.

    In this paper technical standardisation is understood and explained in a model where economic analysis is coupled with an analysis of the political system as proposed in rational choice theory. The aim is to answer both the question why various countries (e.g. the United States versus European...... countries) let either the market or public intervention determine the mode of technical standardisation and the possible implications of these two ways of organizing technical standardisation from an economic and a political point of view. Based upon the analysis of the paper a couple of general policy...... recommendations are made concerning the mode of technical standardisation....

    The advent of global markets elevates the role and importance of culture as a mitigating factor in the diffusion of knowledge and technology and in product and process innovation. This is especially true in the large commercial aircraft (LCA) sector where the production and market aspects are becoming increasingly international. As firms expand beyond their national borders, using such methods as risk-sharing partnerships, joint ventures, outsourcing, and alliances, they have to contend with national and corporate cultures. Our focus is on Japan, a program participant in the production of the Boeing Company's 777. The aspects of Japanese culture and workplace communications will be examined: 1.) the influence of Japanese culture on the diffusion of knowledge and technology in aerospace at the national and international levels; 2.) those cultural determinants-the propensity to work together, a willingness to subsume individual interests to a greater good, and an emphasis on consensual decision making-that have a direct bearing on the ability of Japanese firms to form alliances and compete in international markets; 3.) and those cultural determinants thought to influence the information-seeking behaviors and workplace communication practices of Japanese aerospace engineers and scientists. In this article, we report selective results from a survey of Japanese and U.S. aerospace engineers and scientists that focused on workplace communications. Data are presented for the following topics: importance of and time spent communicating information, collaborative writing, need for an undergraduate course in technical communication, use of libraries, use and importance of electronic (computer) networks, and the use and importance of foreign and domestically produced technical reports.

    1990-01-01

    The nuclear energy discussion is as old as the discovery of nuclear fission. Its technical harnessing is one of the most important basic innovations of this century. The ambivalence of nuclear energy - peaceful and aggresssive utilization habe been equally realized - and potential endangerment by fission products have put a strain on its acceptance worldwide. The forming of public opinion is further complicated by the complexity of the system we call 'nuclear energy'. The beginning of its commercial utilization coincided with the first awareness of the 'limits to growth'. In many discussion and for many groups, also ideologically based ones, nuclear energy plays a substitute role in the social political debate on the 'right' way into the future. By means of one-sided and sometimes distorted representations, many media have contributed to the confusion. Industry and the business world, being interested in nuclear energy, have endeavored to take a stand in its defence, although not always qualitatively or quantitatively appropriate. These endeavors were impeded by sporadic strong politicalization of all relevant decisions. The specific roll behavior of those participating in the discussion was also at times a hindrance. The nuclear energy discussion is not locally limited, it is rather international. This should be taken into consideration in all endeavors for its acceptance. The beginning world-wide climate discussion will inveterately alter the position of nuclear energy and the public's opinion of it. (author)

The survey, although somewhat modified, is based on a similar one that has been conducted at high schools as a part of organized educational program by the Museum of Technical Sciences and Hrvatska Elektroprivreda. Preliminary results show a positive altitude among the student population when it comes to nuclear power plants. As it can be seen from the obtained data (preliminary analysis), this opinion is mostly built on student awareness of nuclear power plants as a clean energy source. (authors)

    Full Text Available Investigations carried out in late 2001 in primary and secondary schools of Belgrade, Novi Sad and Niš comprised students, teachers and associates. The aim of investigations was to get insight into the state-of-the-arts problems and needs of our primary and secondary schools. The paper is a part of investigations, related to the results obtained for students' opinions of their interrelations with teachers as well as opinions of teachers themselves. The sample comprised 727 students of 4th grade of secondary vocational and high schools, 562 students of 8th grade of primary schools 168 secondary school and 107 primary school teachers. We investigated their interrelationships and within this framework the level of potential or current aggressive behavior. The majority of teachers (51% estimated student-teacher relationships mediocre - neither good nor bad. The most frequent problem in students' behavior is, according to the teachers instruction disturbance. One-quarter of teachers find that students offend them, ridicule them, or mock at them in front of others, and 5 per cent complain of physical injury intimidation on the part of students. When a problem comes up, 18 per cent of teachers talk with a student, and nearly 10 per cent of teachers give lower grades in their subject, so as to punish a student for undisciplined behaviors. In teachers' opinion, society, school the least, is to be blamed for the situation.

    Predicting users' online ratings is always a challenge issue and has drawn lots of attention. In this paper, we present a rating prediction method by combining the user opinion spreading process with the collaborative filtering algorithm, where user similarity is defined by measuring the amount of opinion a user transfers to another based on the primitive user-item rating matrix. The proposed method could produce a more precise rating prediction for each unrated user-item pair. In addition, we introduce a tunable parameter λ to regulate the preferential diffusion relevant to the degree of both opinion sender and receiver. The numerical results for Movielens and Netflix data sets show that this algorithm has a better accuracy than the standard user-based collaborative filtering algorithm using Cosine and Pearson correlation without increasing computational complexity. By tuning λ, our method could further boost the prediction accuracy when using Mean Absolute Error (MAE) and Root Mean Squared Error (RMSE) as measurements. In the optimal cases, on Movielens and Netflix data sets, the corresponding algorithmic accuracy (MAE and RMSE) are improved 11.26% and 8.84%, 13.49% and 10.52% compared to the item average method, respectively.

  12. Heterogeneity and subjectivity in binary-state opinion formation systems

    2013-01-01

    In society, there is heterogeneous interaction and randomness in human decision making. In order to unfold the roles and the competition of the two factors mentioned above in opinion formation, we propose a toy model, which follows a majority rule with a Fermi function, on scale-free networks with degree exponent γ. The heterogeneous interaction is related to the connectivity of a person with the interactive parameter β, and the randomness of human decision making is quantified by the interaction noise T. We find that a system with heterogeneity of network topology and interaction shows robustness perturbed by the interaction noise T according to the theoretical analysis and numerical simulation. Then, when T → 0, the homogeneous interaction (β ≃ 0) has a powerful implication for the emergence of a consensus state. Furthermore, the emergence of the two extreme values shows the competition of the heterogeneity of interaction and the subjectivity of human decision making in opinion formation. Our present work provides some perspective on and tools for understanding the diversity of opinion in our society. (paper)

    Online social media such as Twitter are widely used for mining public opinions and sentiments on various issues and topics. The sheer volume of the data generated and the eager adoption by the online-savvy public are helping to raise the profile of online media as a convenient source of news and public opinions on social and political issues as well. Due to the uncontrollable biases in the population who heavily use the media, however, it is often difficult to measure how accurately the online sphere reflects the offline world at large, undermining the usefulness of online media. One way of identifying and overcoming the online-offline discrepancies is to apply a common analytical and modeling framework to comparable data sets from online and offline sources and cross-analyzing the patterns found therein. In this paper we study the political spectra constructed from Twitter and from legislators' voting records as an example to demonstrate the potential limits of online media as the source for accurate public opinion mining, and how to overcome the limits by using offline data simultaneously.

    Efforts are under way to popularize practical energy conservation technologies through verification on real machines in target countries. Possibilities were studied that Malaysian paper making plants would adopt technologies of collecting heat from high-temperature exhaust gas from paper sludge incineration and of effectively utilizing the thus-collected heat. The Malaysian paper making industry produced 800-thousand tons or more in 1998, covering 72% of the total national demand. Heat recovery facilities may be installed in 15 plants. On-site surveys were made into their actual states, and then Genting Sanyen Industrial Paper Sdn. Bhd. was selected as the plant for the model project, and detailed model project feasibility studies were conducted. The studies covered the amount of wastes from paper making, their properties, treatment process, amounts of utilities to be used during system operation, land on which to build the facilities, and a plan for collecting invested funds. As the result, it was concluded in view of the magnitude of the expected fruit that the model project be implemented at this plant. (NEDO)

  16. Cross-correlation patterns in social opinion formation with sequential data

    2016-11-01

    Recent research on large-scale internet data suggests existence of patterns in the collective behavior of billions of people even though each of them may pursue own activities. In this paper, we interpret online rating activity as a process of forming social opinion about individual items, where people sequentially choose a rating based on the current information set comprising all previous ratings and own preferences. We construct an opinion index from the sequence of ratings and we show that (1) movie-specific opinion converges much slower than an independent and identically distributed (i.i.d.) sequence of ratings, (2) rating sequence for individual movies shows lesser variation compared to an i.i.d. sequence of ratings, (3) the probability density function of the asymptotic opinions has more spread than that defined over opinion arising from i.i.d. sequence of ratings, (4) opinion sequences across movies are correlated with significantly higher and lower correlation compared to opinion constructed from i.i.d. sequence of ratings, creating a bimodal cross-correlation structure. By decomposing the temporal correlation structures from panel data of movie ratings, we show that the social effects are very prominent whereas group effects cannot be differentiated from those of surrogate data and individual effects are quite small. The former explains a large part of extreme positive or negative correlations between sequences of opinions. In general, this method can be applied to any rating data to extract social or group-specific effects in correlation structures. We conclude that in this particular case, social effects are important in opinion formation process.

    Nuclear energy perception by the public has not only technical aspects but is also relevant to public debate and related to people's values. The developed countries and affluent societies, have been showing, in particular, a shift towards post-materialist values. Some of these values and needs environment protection, quality of life, involvement in decision-making process (government, corporates) must be taken into account when analysing public opinion towards nuclear energy. That is the reason why since 1992 a yearly nuclear barometer survey has been run, jointly, by the main corporations involved in nuclear research and industry CEA, the French Atomic Energy Commission, COGEMA, EDF and FRAMATOME. This barometer includes not only quantitative indicators but also, several series of questions on public attitude towards risk perception, controversial issues discussed in the media, potential energy sources for the future, politicians credibility etc. In addition, a very detailed public segmentation allows researchers to analyse similarities and differences related to age, gender, level of education of the population. This paper intends to give some concrete examples and current results on French public attitude towards nuclear energy and on the relation between social values and support for nuclear power

    The first papers reporting original research results in technical periodicals and proceedings appeared in the late 17th century. Since that time, the typical scientific paper has evolved from a fairly simple document, accessible to a general audience, to a much more complex one, aimed at a specialized audience. The purpose of this article is to give an overview of what the first scientific papers were like and how they evolved to their present form and style. To facilitate this discussion, the scientific paper`s development has arbitrarily been divided into four stages: the origin and formative years of the scientific paper (1665-1765), emergence of scientific papers written for specialized publications (1765-1865), development of the modem scientific paper (1865-1965), and hyperspecialization and computerization of the modem scientific paper (1965-?).

    Vicente, Renato; Martins, André C R; Caticha, Nestor

    2009-01-01

    We study opinion dynamics in a population of interacting adaptive agents voting on a set of issues represented by vectors. We consider agents who can classify issues into one of two categories and can arrive at their opinions using an adaptive algorithm. Adaptation comes from learning and the information for the learning process comes from interacting with other neighboring agents and trying to change the internal state in order to concur with their opinions. The change in the internal state is driven by the information contained in the issue and in the opinion of the other agent. We present results in a simple yet rich context where each agent uses a Boolean perceptron to state their opinion. If the update occurs with information asynchronously exchanged among pairs of agents, then the typical case, if the number of issues is kept small, is the evolution into a society torn by the emergence of factions with extreme opposite beliefs. This occurs even when seeking consensus with agents with opposite opinions. If the number of issues is large, the dynamics becomes trapped, the society does not evolve into factions and a distribution of moderate opinions is observed. The synchronous case is technically simpler and is studied by formulating the problem in terms of differential equations that describe the evolution of order parameters that measure the consensus between pairs of agents. We show that for a large number of issues and unidirectional information flow, global consensus is a fixed point; however, the approach to this consensus is glassy for large societies

  5. Information Filtering Based on Users' Negative Opinions

    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.

  6. Co-Evolution of Opinion and Strategy in Persuasion Dynamics:. AN Evolutionary Game Theoretical Approach

    Science.gov (United States)

    Ding, Fei; Liu, Yun; Li, Yong

    In this paper, a new model of opinion formation within the framework of evolutionary game theory is presented. The model simulates strategic situations when people are in opinion discussion. Heterogeneous agents adjust their behaviors to the environment during discussions, and their interacting strategies evolve together with opinions. In the proposed game, we take into account payoff discount to join a discussion, and the situation that people might drop out of an unpromising game. Analytical and emulational results show that evolution of opinion and strategy always tend to converge, with utility threshold, memory length, and decision uncertainty parameters influencing the convergence time. The model displays different dynamical regimes when we set differently the rule when people are at a loss in strategy.

Technical operation throughout the entire year was rather smooth, the main faults requiring UXC access being sub-detector power systems and rack-cooling turbines. All such problems were corrected during scheduled technical stops, in the shadow of tunnel access needed by the LHC, or in negotiated accesses or access extensions. Nevertheless, the number of necessary accesses to the UXC averaged more than one per week and the technical stops were inevitably packed with work packages, typically 30 being executed within a few days, placing a high load on the coordination and area management teams. It is an appropriate moment for CMS Technical Coordination to thank all those in many CERN departments and in the Collaboration, who were involved in CMS techni...

    Operational Experience Since the closure of the detector in February, the technical operation of CMS has been quite smooth and reliable. Some minor interventions in UXC were required to cure failures of power supplies, fans, readout boards and rack cooling connections, but all these failures were repaired in scheduled technical stops or parasitically during access dedicated to fixing LHC technical problems. The only occasion when CMS had to request an access between fills was to search for the source of an alarm from the leak-detection cables mounted in the DT racks. After a few minutes of diagnostic search, a leaking air-purge was found. Replacement was complete within 2 hours. This incident demonstrated once more the value of these leak detection cables; the system will be further extended (during the end of year technical stop) to cover more racks in UXC and the floor beneath the detector. The magnet has also been operating reliably and reacted correctly to the 14s power cut on 29 May (see below). In or...

  13. Public opinion on water reuse options

    International Nuclear Information System (INIS)

    Bruvold, W.H.

    1988-01-01

    Public policy on waste water reuse options must be informed by public opinion because it is the public who must pay the cost of developing the option and who will be served by the option in the future. For public policy on reuse, guidance for innovative reuse is not as simple as first believed. It seems that public opinion regarding actual community reuse options is affected by the linkage of several factors, including water conservation, health protection, treatment and distribution costs, and environmental enhancement. Probability sampling was used in 7 studies to select respondents who were queried regarding their opinions on various reclaimed water uses such as ranging from cooling tower water to full domestic use. These 7 are briefly reviewed

    Harmon, J.E.

    1992-01-01

    The first papers reporting original research results in technical periodicals and proceedings appeared in the late 17th century. Since that time, the typical scientific paper has evolved from a fairly simple document, accessible to a general audience, to a much more complex one, aimed at a specialized audience. The purpose of this article is to give an overview of what the first scientific papers were like and how they evolved to their present form and style. To facilitate this discussion, the scientific paper's development has arbitrarily been divided into four stages: the origin and formative years of the scientific paper (1665-1765), emergence of scientific papers written for specialized publications (1765-1865), development of the modem scientific paper (1865-1965), and hyperspecialization and computerization of the modem scientific paper (1965- ).

This study investigated the classroom learning with augmented reality and the impact of student opinions. 97 volunteer undergraduate students took part in this study. Results included data in the form of frequencies, percentages and descriptive statistics. The results show that, with gamification methods, augmented reality content affected students’ opinions in a positive way. When QR codes are used in the classroom, students feel independent from classroom materials and can access various resources. Moreover, students think that, when augmented reality in the classroom is used, education is more enjoyable.

    With more than 20 windfarms now in operation in the UK, public responses to the reality rather than to the idea are emerging. The evidence is mixed: most opinion polls show overall strong support, but there are, equally, signs of strong local opposition in some areas and a general polarisation of views. This paper attempts to explore the way in which local and national attitudes and views have developed, looking in particular at the role of the Government, academia, and the media. It argues for more constructive debate aimed at developing a consensus on the UK's 'carrying capacity' for windfarms. (Author)

    Blados, Walter R.; Pinelli, Thomas E.; Kennedy, John M.; Barclay, Rebecca O.

    1990-01-01

    This paper formulates and studies two propositions. Proposition 1 states that information that is external to the aerospace organization tends to be used less than internal sources of information; the more geographically removed the information is from the organization, the less likely it is to be used. Proposition 2 states that of the various sociometric variables assumed to influence the use of an information channel or source, perceived accessibility exerts the greatest influence. Preliminary analysis based on surveys supports Proposition 1. This analysis does not support Proposition 2, however. Evidence here indicates that reliability and relevance influence the use of an information source more than the idea of perceived accessibility.

    Since early 1988 intensive efforts have been under way to produce a new and improved Standard Technical Specification. The program involves a coordinated effort between utility personnel representing each of the four nuclear steam supply system (NSSS) product lines, the NSSS vendors, and the US Nuclear Regulatory Commission (NRC). This intensive work period is actually the culmination of a decade of rhetoric about shortcomings of the existing technical specifications. Work on the improved technical specifications provided a unique forum for intense philosophical discussions between the users and enforcers of technical specifications, the outcome of which could have an impact on all licensees. Some of the more intriguing difficulties in the use and application of existing technical specifications, as well as discussions of the resolutions being applied in the improved technical specifications and the dilemmas remaining to be resolved are discussed in the paper

    Engineering technology programs are characterized by their focus on application and practice, and by their approximately 50/50 mix of theory and laboratory experience. Engineering technology graduates are employed across the technological spectrum and are often found in areas that deal with application, implementation, and production. Yet we know very little about the communications practices and information-use skills of engineering technology students. In this paper, we report selected results of an exploratory study of engineering technology students enrolled in three U.S. institutions of higher education. Data are presented for the following topics: career goals and aspirations; the importance of, receipt of, and helpfulness of communications and information-use skills instruction; collaborative writing; use of libraries; and the use of electronic (computer) networks.

  10. TECHNICAL COORDINATION

    A. Ball

    Overview From a technical perspective, CMS has been in “beam operation” state since 6th November. The detector is fully closed with all components operational and the magnetic field is normally at the nominal 3.8T. The UXC cavern is normally closed with the radiation veto set. Access to UXC is now only possible during downtimes of LHC. Such accesses must be carefully planned, documented and carried out in agreement with CMS Technical Coordination, Experimental Area Management, LHC programme coordination and the CCC. Material flow in and out of UXC is now strictly controlled. Access to USC remains possible at any time, although, for safety reasons, it is necessary to register with the shift crew in the control room before going down.It is obligatory for all material leaving UXC to pass through the underground buffer zone for RP scanning, database entry and appropriate labeling for traceability. Technical coordination (notably Stephane Bally and Christoph Schaefer), the shift crew and run ...

    Breast surgeons often see women for second opinions for abnormalities found on breast imaging. For second opinions, these images are submitted for review and interpretation by dedicated breast imagers. This study evaluated the conformity of results among interpretation of imaging submitted from outside hospitals both from tertiary care centers, as well as community programs, in an attempt to evaluate the utility of this practice for the sake of clinical management and resource utilization. A retrospective chart review was conducted on all breast patients that submitted outside imaging films for the years 2011 to 2013 at Rush University Medical Center (RUMC). The radiologic diagnosis and each patient's proposed management plan was collected and evaluated for concordance between the outside institutions and RUMC. A total of 380 patients who presented for second opinions with an interpretation of outside exams were evaluated. In 47.4 % [95 % confidence interval (CI) 42.4-52.4] of cases there was distinct variance in radiologic impression. For 53.5 % (95 % CI 48.4-58.5) of patients, there was a change in recommended management plan, which included recommendations for either additional imaging or need for additional biopsy. In total, this changed the overall surgical management in 27.1 % (95 % CI 22.8-31.9) of cases. In six patients, the reinterpretation of outside imaging detected new malignancies not previously identified. Overall, 83.7 % (95 % CI 79.7-87.1) of patients who submitted imaging from outside institutions chose to complete the remainder of their treatment at RUMC. The practice of second opinion review changed overall definitive management at our specialty center in more than one in four cases. In addition, the review identified six previously unrecognized malignancies. Given this data, the practice of second opinions and interpretation of outside exams should continue despite the additional resources required.

  9. Assessment of technical risks

    Energy Technology Data Exchange (ETDEWEB)

    Jaeger, T A [Bundesanstalt fuer Materialpruefung, Berlin (Germany, F.R.)

    1978-01-01

    The safety of technical systems is so difficult to assess because the concept 'risk' contains technical-scientific factors as well as components of individual and social psychology. Immediate or short-term hazards of human life as i.e. caused by the operation of industrial plants and mediate and thus long-term hazards have to be distinguished. Characteristic for the second hazard groups is the great time-lag before the effect takes place. Thus a causal relationship can be recognized only late and not definitely. Even when the causes have been obviated the effects still show. The development of a systems-analytical model as a basis of decisive processes for the introduction of highly endangered large-scale technologies seems particularly difficult. A starting point for the quantification of the risk can still be seen in the product of the probability of realization and the extent of the damage. Public opinion, however, does not base its evaluations on an objective concept of risk but tends to have an attitude of aversion against great and disastrous accidents. On the other hand, plenty of slight accidents are accepted much more easily, even when the amount of deadly victims from accidents reaches dimensions beyond those of the rare large-scale accidents. Here, mostly the damage possible but not the probability of its occurence is seen, let alone the general use of the new technology. The value of the mathematical models for estimating risks is mainly due to the fact that they are able to clear up decisions.

    The biogas potentials from biosludges from six different pulp- and paper mills have been evaluated. It ranged from 100 - 200 mL CH{sub 4}/g VS (volatile solids) for all six mills where five of them gave results between 150 - 200 mL CH{sub 4}/g VS. Long-term semi-continuous trials with biosludges from two of the mills showed stable biogas production throughout the testing period. Pretreatments with enzymes and ultrasound were tested but showed no significant effect on the methane potential. The investment costs for two production plants were calculated. For a small plant using 7 ton biosludge TS/d (total solids per day), producing 305 000 Nm3 CH{sub 4}/yr the investment cost was estimated to 30 MSEK and for a larger plant using 20 ton biosludge TS/d, producing 871 000 Nm3 CH{sub 4}/yr the investment cost was estimated to 51 MSEK (1 USD approx 7 SEK)

    Studies indicate that communications and information-related activities take up a substantial portion of an engineer's work week; therefore, effective communications and information-use skills are one of the key engineering competencies that early career-stage aerospace engineers and scientists must possess to be successful. Feedback from industry rates communications and information-use skills high in terms of their importance to engineering practice; however, this same feedback rates the communications and information-use skills of early career-stage engineers low. To gather adequate and generalizable data about the communications and information-related activities of entry-level aerospace engineers and scientists, we surveyed 264 members of the AIAA who have no more than 1-5 years of aerospace engineering work experience. To learn more about the concomitant communications norms, we compared the results of this study with data (1,673 responses) we collected from student members of the AIAA and with data (341 responses) we collected from a study of aerospace engineering professionals. In this paper, we report selected results from these studies that focused on the communications practices and information-related activities of early career-stage U.S. aerospace engineers and scientists in the workplace.

    International Nuclear Information System (INIS)

    Gieci, Adam; Maly, Stanislav; Palecek, Milos

    2012-01-01

    The following public opinion surveys are described: public opinion on nuclear power plants by the end of 2010; first public opinion polls after Fukushima in the US, UK and France; and public opinion and the future of nuclear in Japan. The following issues are discussed: Has nuclear any perspective after Fukushima? Will public opinion change after the Fukushima accident like it did after the TMI event? Will public opinion change after the Fukushima accident like it did after the oil spill accident in the Gulf of Mexico? In conclusion the new approaches to the fight for public confidence after Fukushima are described. (orig.)

  14. High school and university students’ opinions about politics

    2011-01-01

    Full Text Available This paper is a part of a larger thesis, which compares two groups’ relations to politics, based on empirical sources. The main question, which can be answered only partly in this paper is, what are the particularities of the political culture of the studied populations?Results of study support that in several questions differences based on age – education level – locality proved to be stronger than ethnical ones, but the second type of differences are also significant i.e. in perceiving a few social gaps, trust in international institutions etc. Social background seems to play a sporadic role in shaping opinions about politics. Diffuse support for democracy is completed with weaker specific support. Romanian university students seem to have the most positive attitude toward direction and advances of Romanian democracy. Trust in institutions and perception of governments’ performance is connected, as a recent empirical study also confirmed based on the results of EVS and WVS of the last two decades (Tufiș 2010. Relations among the studied elements of political culture indicate that new directions and methods would be needed in order to find empirically supported explanations. Students develop/form their opinions about politics probably more based on the attitudes brought from socialization agents, than on their own information and experience.

  17. Cultural Scripts and the Speech Act of Opinions in Irish English: A Study amongst Irish and Polish University Students

    Directory of Open Access Journals (Sweden)

    Weronika Gąsior

    2015-06-01

    Full Text Available Studies in pragmatics have been limited to a handful of illocutionary acts such as requests, apologies or compliments, and opinions remain underrepresented in the existing literature. In this paper I present the results of a study of opinions in Irish English, conducted in an intercultural environment of Irish-Polish interactions. Departing from a traditional approach of speech act realisation studies, I applied the theory of cultural scripts to analyse opinions. In contrasting the Irish and Polish formulas for expressing opinions, as well as sociopragmatic attitudes towards this speech act, a difference in the cultural scripts for opinions in each culture was observable. Apart from already documented Polish frankness in opinions, the study discovered also a rational approach to presenting good arguments to support one’s assertions among the participants. In relation to the Irish script for opinions, the findings are in line with previous classifications of opinions in Australian English, showing a certain level of variational uniformity amongst the English-speaking cultures in this regard.

  20. STUDENT OPINIONS ON MANAGEMENT OF DISTANCE EDUCATION APPLICATIONS

    Directory of Open Access Journals (Sweden)

    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.

  1. A Second Opinion is Worth the Cost - 12479

    Madsen, Drew [Project Time and Cost Inc. (United States)

    2012-07-01

    This paper, 'A Second Opinion is Worth the Cost', shows how a second opinion for a Department of Energy (DOE) Project helped prepare and pass a DOE Order 413.3A 'Program and Project Management for the acquisition of Capital Assets' Office of Engineering and Construction Management (OECM) required External Independent Review (EIR) in support of the approved baseline for Critical Decision (CD) 2. The DOE project personnel were informed that the project's Total Project Cost (TPC) was going to increase from $815 million to $1.1 billion due to unforeseen problems and unexplained reasons. The DOE Project Team determined that a second opinion was needed to review and validate the TPC. Project Time and Cost, Inc. (PT and C) was requested to evaluate the cost estimate, schedule, basis of estimate (BOE), and risk management plan of the Project and to give an independent assessment of the TPC that was presented to DOE. This paper will demonstrate how breaking down a project to the work breakdown structure (WBS) level allows a project to be analyzed for potential cost increases and/or decreases, thus providing a more accurate TPC. The review Team's cost analyses of Projects identified eight primary drivers resulting in cost increases. They included: - Overstatement of the effort required to develop drawings and specifications. - Cost allocation to 'Miscellaneous' without sufficient detail or documentation. - Cost for duplicated efforts. - Vendor estimates or quotations without sufficient detail. - The practice of using the highest price quoted then adding an additional 10% mark-up. - Application of Nuclear Quality Assurance (NQA) highest level quality requirements when not required. - Allocation of operational costs to the Project Costs instead of to the Operating Expenses (OPEX). OPEX costs come from a different funding source. - DOE had not approved the activities. By using a Team approach with professionals from cost, civil

    For the reporting period, the CMS common systems and infrastructure worked well, without failures that caused significant data losses. One more disconnection of the magnet cold box occurred in the shadow of interruptions in data taking, caused by a series of technical faults. The recognition during 2012 that re-connection can only safely be done at around 2 T implies a minimum magnet recovery time of 12 hours and raises serious concerns about the number of ramping cycles of the magnet these incidents cause. This has triggered studies of how to make the cryo-system of the magnet more robust against failures. The proton-proton run ended just before the end-of-year CERN closure, during which CASTOR was installed on the negative end of CMS and both ZDC calorimeters were installed in TAN absorbers the LHC tunnel, in preparation for the heavy-ion run. The installation of CASTOR was an excellent “engineering test” of procedures for working in an activated environment. Despite some technical pr...

    Summary of progress since last CMS week. Ten years of construction work have been completed. CMS is closed, in very close to the ideal low luminosity configuration, and performed well in the first tests with LHC beam. Behind this encouraging news is the story of a summer of intense commitment by many teams (from the collaboration and 3 CERN departments) working together, against the clock and despite many minor setbacks, to ensure that the experiment was ready to play a leading role in the excitement of September 10. Following beampipe bakeout and refill with pure neon, a magnificent effort by the ECAL group and the pt 5 technical crew made it possible to install and commission all 4 ECAL endcap Dees before the end of August. In the shadow of this activity, the barrel and forward pixel trackers and part of the beam monitoring were installed within the vac tank. The pt 5 technical teams then succeeded in safely removing the 20t installation tables and their support blocks from beneath the already installed ...

      Operational experience 2011 CMS is approaching the end of a very successful year of operation. Proton- proton running ended in the late afternoon of 30th October with a stunning 5.73 fb–1 delivered by LHC, of which CMS recorded 5.22 fb–1. During heavy-ion operation, which continues until 7th December, both the accelerator and the CMS detector have also performed very well. Despite the encouraging overall reliability of technical operation, several infrastructure failures which occurred since the last Bulletin are worthy of mention, with one leading for the first time to significant data-loss. On 10th July, a CERN-wide power failure brought down essentially all services including the magnet, due to an MCS setting being left in “manual” after the recent technical stop, but there was no significant damage and the detector was operational before the LHC, despite a slow and tortuous recovery (one of several indications this year that there is room for improve...

  6. 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

    Following the 2005 contractual framework amendment, the expanding role of community pharmacy team members required a shift in entrenched views on roles and duties. This study aimed to report on community pharmacists' opinions on skill mix and explore how they can be addressed so that skill mix may be optimised. An invitation to complete an online questionnaire was distributed via email, marked for the attention of the lead pharmacist. Following a low response, a paper-based questionnaire was sent to all community pharmacies in England (n = 11,816). Questions elicited data about the respondent, the pharmacy (including staffing profile) and opinions on skill mix. A total of 1154 returns were received, representing a 10% response rate. Of these, most were pharmacy chains (76%; n = 877), with 5-9 staff (54%; n = 600); commonly open 40-49 hours (42%; n = 487), dispensing <6000 prescriptions per week (41%, n = 533). From 26 statements on skill mix, three factors were identified by principal-components factor analysis: 'working well', 'feeling the pressure' and 'open to development'. Characteristics associated with 'working well': pharmacy owners, single businesses, with pharmacy technician(s), dispensing fewer prescriptions and open shorter hours. Characteristics associated with 'feeling the pressure': pharmacy chains, open longer hours, large numbers of prescriptions and relief pharmacists. Characteristics associated with 'open to development': recently qualified, second pharmacists, working longer hours, chains and dispensing lower numbers of prescriptions. Although limited by a low response, results suggest being in a position to influence (more experienced, business owners) may be associated with more positive opinions. Further training (including about legalities and leadership) could contribute to optimising skill mix in community pharmacies. © 2017 Royal Pharmaceutical Society.

  10. Audit firm tenure and qualified opinions: New evidence from Spain

    Directory of Open Access Journals (Sweden)

    2013-06-01

    Full Text Available The 2010 Green Paper on Audit Policy by the European Commission has explicitly questioned the sufficiency of audit rotation rules established by European Union Members to guarantee auditor independence. In addition, the Paper clearly states that more research is needed regarding the effects of long audit tenures on independence. In this article, we have replicated the research by Ruiz-Barbadillo, Gómez-Aguilar, and Biedma (2005 about the effects of audit firm tenure on independence with more updated data. However, unlike them, we have performed panel data estimations instead of pooled regression. Our approach allows for a better control of individual unobserved heterogeneity, thus reducing potential problems caused by omitted variable bias. While Ruiz-Barbadillo et al. reported an unexpected positive effect of tenure on the likelihood of audit qualifications, we do not show any significant effect of tenure on the opinion of the audit report. Our results are robust to various sensitivity analyses.

    In November 1987, the five-member Differing Professional Opinions Special Review Panel established by the Executive Director for Operations of the US Nuclear Regulatory Commission to review agency policies and procedures for handling differing professional opinions (DPOs) presented its findings and recommendations in NUREG-1290. The issuance of that report completed the first task of the panel's charter. In accordance with Manual chapter 4125, Section L, and the charter of the Special Review Panel, the panel's second task was to ''...review...the DPOs submitted subsequent to the previous Panel's review, in order to identify any employee whose DPO made a significant contribution to the Agency or to the public safety but who has not yet been recognized for such contribution.'' This Addendum provides the findings of that review

    Employee benefits managers arrange addictive disease treatment insurance coverage for the majority of people in the United States but little is known about these decision-makers. Managers were surveyed to learn their opinions about addiction treatment. Subjects were 131 people (61 percent female, 94 percent white, average age 46, average of 14 years in the human resources field). Managers were asked to rank health benefits (physical health, dental, alcohol-drug, vision, mental health, employee assistance program, and pharmaceuticals) on 15 dimensions. Managers ranked alcohol-drug abuse treatment worst on fiveitems and second to the worst on another four of the 15 dimensions. On the item considered most important by the managers, respondents noted that employees often (2.8) ask for improved physical health benefits but rarely do so for alcohol and drug (4.1) benefits (p < .001). Education of workers and payers will be needed to change opinions about treatment of addictive disorders.

    In recent years, the theory that on-line clinical decision support systems can improve patients' safety among hospitalised individuals has gained greater acceptance. However, the feasibility of implementing such a system in a middle or low-income country has rarely been studied. Understanding the current prescription process and a proper needs assessment of prescribers can act as the key to successful implementation. The aim of this study was to explore physicians' opinions on the current prescription process, and the expected benefits and perceived obstacles to employ Computerised Physician Order Entry in an Iranian teaching hospital. Initially, the interview guideline was developed through focus group discussions with eight experts. Then semi-structured interviews were held with 19 prescribers. After verbatim transcription, inductive thematic analysis was performed on empirical data. Forty hours of on-looker observations were performed in different wards to explore the current prescription process. The current prescription process was identified as a physician-centred, top-down, model, where prescribers were found to mostly rely on their memories as well as being overconfident. Some errors may occur during different paper-based registrations, transcriptions and transfers. Physician opinions on Computerised Physician Order Entry were categorised into expected benefits and perceived obstacles. Confidentiality issues, reduction of medication errors and educational benefits were identified as three themes in the expected benefits category. High cost, social and cultural barriers, data entry time and problems with technical support emerged as four themes in the perceived obstacles category. The current prescription process has a high possibility of medication errors. Although there are different barriers confronting the implementation and continuation of Computerised Physician Order Entry in Iranian hospitals, physicians have a willingness to use them if these systems

    We propose new deterministic and stochastic models for synchronization of clocks in nodes of distributed networks. An external accurate time server is used to ensure convergence of the node clocks to the exact time. These systems have much in common with mathematical models of opinion formation in multiagent systems. There is a direct analogy between the time server/node clocks pair in asynchronous networks and the leader/follower pair in the context of social network models.

    Conclusions. The most positive beliefs related to breastfeeding refer to the special relation between an infant and its mother, the belief that breastfeeding is an ideal solution for a baby and the appreciation of its economical aspect. Women are aware of the fact that breastfeeding is a challenge for them. Two main factors influence their opinion: the age of women and the number of births.

  19. Public Opinion Survey Data to Measure Sympathy and Support for Islamist Terrorism: A Look at Muslim Opinions on Al Qaeda and IS

    Directory of Open Access Journals (Sweden)

    Alex P. Schmid

    2017-02-01

    Full Text Available This Research Paper seeks to explore what ‘sympathy’ and ‘support’ actually mean when it comes to terrorism. The text addresses some of the problems of public opinion surveys, includes a conceptual discussion and then continues with the presentation of data from public opinion surveys. It notes that opinion polls can be helpful in gauging (verbal support for terrorism but also finds that the questions asked in opinion polls are generally lacking precision while the answers are often influenced by political pressures. When translating (generally low percentages of sympathy and support for al Qaeda and so-called Islamic State in various countries into actual population figures, it emerges that there is a sizeable radical milieu in both Muslim-majority countries and in Western Muslim diasporas, held together by the world wide web of the internet. While large majorities of Muslims in most countries have no love for jihadist extremists, there are more than enough breeding grounds for terrorism. The Research Paper concludes that better instruments for measuring sympathy and support for jihadist terrorism are needed to inform counter-terrorist strategies.

    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.

    2007-08-01

    The objectives were to determine who establishes restaurant portion sizes and factors that influence these decisions, and to examine chefs' opinions regarding portion size, nutrition information, and weight management. A survey was distributed to chefs to obtain information about who is responsible for determining restaurant portion sizes, factors influencing restaurant portion sizes, what food portion sizes are being served in restaurants, and chefs' opinions regarding nutrition information, health, and body weight. The final sample consisted of 300 chefs attending various culinary meetings. Executive chefs were identified as being primarily responsible for establishing portion sizes served in restaurants. Factors reported to have a strong influence on restaurant portion sizes included presentation of foods, food cost, and customer expectations. While 76% of chefs thought that they served "regular" portions, the actual portions of steak and pasta they reported serving were 2 to 4 times larger than serving sizes recommended by the U.S government. Chefs indicated that they believe that the amount of food served influences how much patrons consume and that large portions are a problem for weight control, but their opinions were mixed regarding whether it is the customer's responsibility to eat an appropriate amount when served a large portion of food. Portion size is a key determinant of energy intake, and the results from this study suggest that cultural norms and economic value strongly influence the determination of restaurant portion sizes. Strategies are needed to encourage chefs to provide and promote portions that are appropriate for customers' energy requirements.

    1989-01-01

    After 2 yr of preparation, 1988 finally saw the nuclear industry writing operator-oriented technical specifications. This effort is a continuation of previous efforts to develop improved and usable standard technical specifications (STSs), and is being conducted by the four nuclear steam supply system vendor owners' groups under the auspices of the Nuclear Management Resources Council. Each participant is currently preparing a set of improved STSs based on a writer's guide that was developed through a combined industry effort. In May of 1987, a Human Factors Improvements to Technical Specifications (HFITS) task group was formed to prepare a writer's guide for improved, industrywide STSs. This task group was composed of two representatives from each owners' group, one with a human factors background and one with some operations background. Two documents were prepared in 6 months, a human factors report laying the groundwork for the considerations to go into technical specifications and a writer's guide for their preparation. This paper reports on the application of this writer's guide to the writing of improved STS

This paper examined the perceptions of nuclear power plant engineers of an electric power company, about public values and concerns regarding nuclear power generation (image of public opinion), and compared them with actual public opinion. The image of public opinion was surveyed by questionnaire method. In the questionnaire, the subjects were asked to estimate the most preferred answer given to questions posed to the Japanese public. For some questions, subjects were asked to estimate the percentage of Japanese who selected a certain answer for a question or the distribution of the answers. The results showed: (1) Nuclear power plant engineers correctly recognized the existence of high anxiety in the public's mind concerning nuclear power generation. (2) Engineers were apt to underestimate the percentage of Japanese who think nuclear power generation is useful in our society. (3) The majority of Japanese assume that when nuclear power plant accidents occur radioactive leakage is so severe that it affects the health of inhabitants. However, the engineers were apt to estimate that the majority of Japanese think radioactive leakage is not so severe. (4) Engineers correctly recognized that the majority of Japanese think it is a realistic option to use the nuclear power generation. However, they incorrectly estimated that only 40% of Japanese think it is a realistic option to use the nuclear power generation when in fact 67% think so. These gaps between public opinion and the image of public opinion by the engineers were classified into two groups, one that stems from the cognitive bias when people estimate public opinion and one that is inherent in the engineers of nuclear power plants.

    The ocean modelling is a rapidly evolving science and a large number of results have been published. Several categories of papers are of particular interest for this review: the papers published by the international atomic institutions, such as the NEA (for the CRESP or Subseabed Programs), the IAEA (for example the Safety Series, the Technical Report Series or the TECDOC), and the ICRP, and the papers concerned by more fundamental research, which are published in specific scientific literature. This paper aims to list some of the most relevant publications for the CRESP purposes. It means by no way to be exhaustive, but informative on the incontestable progress recently achieved in that field. One should note that some of these papers are so recent that their final version has not yet been published

    Overview Once again, the bulk of this article reviews the intense activity of a recently completed shutdown, which, although quite unforeseeable until a few weeks before it started, proved by its success that our often advertised capability to conduct major maintenance within a two month period is real. Although safely completed, on-time to remarkable precision, the activity was not without incident, and highlighted our dependence on many experienced, specialist teams and their precise choreography. Even after the yoke was safely closed, magnet re-commissioning and beampipe pumpdown showed new and thought-provoking behaviour. The struggle to maintain adequate technical resources will be a pre-occupation over the coming months, in parallel with the start of truly sustained operation, for which various procedures are still being put in place. Planning for future shutdowns must now become a high priority, with many working groups and task forces already in existence to prepare infrastructure improvements and to...

    Full Text Available Towards the Application of Speech Act Theory to Opinion Mining The paper refers to the pragmatics’ perspective on opinion mining in Polish and English, inspired by the discrepancy between the coverage of sentiment analysis and the market demand. An analysis of speech acts expressed in opinion texts reveals that almost half of all opinions include ways of indirect evaluation that might not get extracted while applying traditional methods of sentiment analysis based on direct evaluative vocabulary and polarity lexicons. Coding of sentiment with respect to speech acts could vastly broaden data mining results within an NLP-system.   O zastosowaniu teorii aktów mowy w ekstrakcji danych z tekstów opinii internetowych Jedno z aktualnych zagadnień językoznawstwa komputerowego, jakim jest automatyczne badanie wydźwięku wypowiedzi, nie uwzględniło dotychczas w wystarczającym stopniu pragmatyki językoznawczej, np. aktów mowy Austina (1961 i Searla (1969, a zatem również implicytnych sposobów wyrażania ewaluacji.

    Public opinion becomes increasingly salient in the ex post evaluation stage of large infrastructure projects which have significant impacts to the environment and the society. However, traditional survey methods are inefficient in collection and assessment of the public opinion due to its large quantity and diversity. Recently, Social media platforms provide a rich data source for monitoring and assessing the public opinion on controversial infrastructure projects. This paper proposes an assessment framework to transform unstructured online public opinions on large infrastructure projects into sentimental and topical indicators for enhancing practices of ex post evaluation and public participation. The framework uses web crawlers to collect online comments related to a large infrastructure project and employs two natural language processing technologies, including sentiment analysis and topic modeling, with spatio-temporal analysis, to transform these comments into indicators for assessing online public opinion on the project. Based on the framework, we investigate the online public opinion of the Three Gorges Project on China's largest microblogging site, namely, Weibo. Assessment results present spatial-temporal distributions of post intensity and sentiment polarity, reveals major topics with different sentiments and summarizes managerial implications, for ex post evaluation of the world's largest hydropower project. The proposed assessment framework is expected to be widely applied as a methodological strategy to assess public opinion in the ex post evaluation stage of large infrastructure projects. - Highlights: • We developed a framework to assess online public opinion on large infrastructure projects with environmental impacts. • Indicators were built to assess post intensity, sentiment polarity and major topics of the public opinion. • We took the Three Gorges Project (TGP) as an example to demonstrate the effectiveness proposed framework.

    The increasing use and ubiquity of the Internet facilitate dissemination of word-of-mouth through blogs, online forums, newsgroups, and consumer's reviews. Online consumer's reviews present tremendous opportunities and challenges for consumers and marketers. One of the challenges is to develop interactive marketing practices for making connections with target consumers that capitalize consumer-to-consumer communications for generating product adoption. Opinion mining is employed in marketing to help consumers and enterprises in the analysis of online consumers' reviews by highlighting the strengths and weaknesses of the products. This paper describes an opinion mining system based on novel review and feature ranking methods to empower consumers and enterprises for identifying critical product features from enormous consumers' reviews. Consumers and business analysts are the main target group for the proposed system who want to explore consumers' feedback for determining purchase decisions and enterprise strategies. We evaluate the proposed system on real dataset. Results show that integration of review and feature-ranking methods improves the decision making processes significantly.

    External experts can be consulted at different stages of an HTA. When using vague information sources, it is particularly important to plan, analyze, and report the information processing in a standardized and transparent way. Our objective was to search and analyze recommendations regarding where and how to include expert data in HTA. We performed a systematic database search and screened the Internet pages of seventy-seven HTA organizations for guidelines, recommendations, and methods papers that address the inclusion of experts in HTA. Relevant documents were downloaded, and information was extracted in a standard form. Results were merged in tables and narrative evidence synthesis. From twenty-two HTA organizations, we included forty-two documents that consider the use of expert opinion in HTA. Nearly all documents mention experts in the step of preparation of the evidence report. Six documents address their role for priority setting of topics, fifteen for scoping, twelve for the appraisal of evidence and results, another twelve documents mention experts when considering the dissemination of HTA results. During the assessment step, experts are most often asked to amend the literature search or to provide expertise for special data analyses. Another issue for external experts is to appraise the HTA results and refer them back to a clinical and social context. Little is reported on methods of expert elicitation when their input substitutes study data. Despite existing recommendations on the use of expert opinion in HTA, common standards for elicitation are scarce in HTA guidelines.

    In recent decades significant developments in end-of-life care have taken place in The Netherlands. There has been more attention for palliative care and alongside the practice of euthanasia has been regulated. The aim of this paper is to describe the opinions of physicians with regard to the relationship between palliative care and euthanasia, and determinants of these opinions. Cross-sectional. Representative samples of physicians (n = 410), relatives of patients who died after euthanasia and physician-assisted suicide (EAS; n = 87), and members of the Euthanasia Review Committees (ERCs; n = 35). Structured interviews with physicians and relatives of patients, and a written questionnaire for the members of the ERCs. Approximately half of the physicians disagreed and one third agreed with statements describing the quality of palliative care in The Netherlands as suboptimal and describing the expertise of physicians with regard to palliative care as insufficient. Almost two thirds of the physicians disagreed with the suggestion that adequate treatment of pain and terminal care make euthanasia redundant. Having a religious belief, being a nursing home physician or a clinical specialist, never having performed euthanasia, and not wanting to perform euthanasia were related to the belief that adequate treatment of pain and terminal care could make euthanasia redundant. The study results indicate that most physicians in The Netherlands are not convinced that palliative care can always alleviate all suffering at the end of life and believe that euthanasia could be appropriate in some cases.

  6. Public opinion about large offshore wind power: Underlying factors

    Firestone, Jeremy; Kempton, Willett

    2007-01-01

    This paper address factors underlying public opinion regarding offshore wind power based on a survey of residents near a proposed development off Cape Cod, MA, USA. Supporters are found to be younger, better educated, and more likely to own their own home. Opponents are more likely to earn over $200,000/year, and more likely to expect to see the project from their daily routine. The overwhelming majority of the population expects negative impacts from the project; much smaller numbers expect positive effects. When asked which factors most affected their position, the most frequently mentioned was damage to marine life/environmental impacts, followed by electricity rates, aesthetics, and impacts on fishing or boating. When the expectations expressed by our respondents are compared with the findings of the project's draft Environmental Impact Statement, many of the beliefs upon which opinion are based appear to be factually incorrect. Finally, we tested whether change in the project would affect support. The biggest change was an increase in the level of support, by 47% of the sample, if the project was the first of 300 such projects, in sum having proportionately larger impacts as well as greater benefits. Implications of this research are discussed

    Collecting and disseminating information about the public opinion on a regulatory process gives visibility to the silent social support and facilitates the process, which often confronts resistance from interest groups. This paper presents a survey about a proposed legislation on tobacco in its final stages and its results, and some considerations on the use of this sort of information in change processes. Cross sectional descriptive study. In December 2005 a brief telephone survey was made to a population sample of 18 and more years of age (N=830) in Catalonia (Spain). The questionnaire explored opinions on the proposed regulations under discussion. We present the degree of support and the rating of nine regulatory measures, stratified by the respondents use of tobacco. Daily smokers are 26.3% of the surveyed population. Awareness and general support for tobacco regulation are very high. Aspects with wider support include bans on sales to minors (97.3%), smoking in enclosed public places (92.8%) and workplaces (89%), and publicity (90.8%). The aspect with less social support is banning smoking in bars and cafes (80.2%). The population supports widely tobacco regulation. This reinforces the process and weakens the arguments of those against it. Although smokers are less supportive, most of them accept the regulations, except for limitations in bars and cafes.

  9. Topical opinion paper - Apparent Discrepancies Between Nuclear and Conventional Seismic Standards

    International Nuclear Information System (INIS)

    Donald, John; Smith, Ian

    2003-01-01

    The differences between nuclear and conventional seismic standards are considered and their potential significance discussed. The approach to the design of nuclear facilities is appropriately both more rigorous and conservative than that required by conventional seismic standards and codes. For nuclear seismic design the requirements can be presented as assessment principles, e.g., NII SAPs or a safety guide e.g. IAEA; Seismic Design and Qualification for Nuclear Power Plants. The adoption of novel methods or designs are required to be supported by appropriate research and development with the ability to cite a precedent within the industry being a powerful endorsement. The method adopted must reliably predict the seismic response of the item to be qualified, including the seismic response of attached or supported Structures, Systems and Components. (SSC's) The traditional method adopted for seismic qualification by analysis has been based on linear elastic analyses. This is justified on the basis that the response is reliably predicted and realistic, provided that the elements remain elastic. In contrast the benefit of ductile behaviour of conventional structures within the design envelope has long been recognised and used as the basis to justify significant reductions in the seismic demand. Provided the acceptance criteria are met, the SAPs do not preclude and the IAEA safety guide specifically permits non linear behaviour within the design envelope for category 1 items. Both the current nuclear practice and the current conventional seismic standards can be classified as 'force based'. The displacement based approach, also referred to as performance based engineering (PBE), has been developed as a powerful tool in the evaluation and seismic retrofit of existing structures. This approach could be equally valid to the design of new structures and can be used to represent elastic or non linear behaviour although the full benefit will only be realised in the latter case. PBE shares many common features with the nuclear ideals, namely: - Defining the performance objectives specific for a particular structure; - Ready evaluation of multiple limit states; - Seeking to predict real behaviour as closely as feasible by considering the combination of soil and foundation effects, cracking and stiffness and strength degradation etc. and permitting the tracking of the development of mechanisms; - Enhancing the understanding of the seismic response by the identification of redistribution between load paths and the identification of the potential and probable controlling mechanisms; - Enabling the provision of a consistent level of protection against reaching a specified limit state. An initial evaluation of the relevance of displacement based methods to nuclear power plant structures has been undertaken by the U.S. Nuclear Regulatory Commission. They concluded that the approach has no advantages over force based methods for the design where the response is required to remain within the linear elastic range. They also identified advantages over the use of non linear time history analyses in the evaluation of seismic margin and the production of fragility curves. The displacement based methods require explicit consideration of many previously implicit or hidden assumptions. Recommendations: The reluctance of the nuclear industry to adopt the displacement based analysis and design methods is identified as a significant discrepancy between current nuclear practice and the conventional design methods that are available. The ideal and recommended course of action is to encourage use of PBE and displacement based analysis and design where appropriate and support nuclear industry focussed research on methodologies. The development of guidelines on the appropriate use of PBE and displacement methods would encourage the adoption of the approach. Before guidelines could be developed and agreed, studies and research to assess the various displacement based analysis methods available and to demonstrate that the methodologies would be sufficiently robust to yield reliable outputs, particularly for SSC's would be required

    2018-01-01

    Background In the recent years, social networking sites (SNSs, also called social media) have been adopted in organ donation campaigns, and recruiting opinion leaders for such campaigns has been found effective in promoting behavioral changes. Objective The aim of this paper was to focus on the dissemination of organ donation tweets on Weibo, the Chinese equivalent of Twitter, and to examine the opinion leadership in the retweet network of popular organ donation messages using social network analysis. It also aimed to investigate how personal and social attributes contribute to a user’s opinion leadership on the topic of organ donation. Methods All messages about organ donation posted on Weibo from January 1, 2015 to December 31, 2015 were extracted using Python Web crawler. A retweet network with 505,047 nodes and 545,312 edges of the popular messages (n=206) was constructed and analyzed. The local and global opinion leaderships were measured using network metrics, and the roles of personal attributes, professional knowledge, and social positions in obtaining the opinion leadership were examined using general linear model. Results The findings revealed that personal attributes, professional knowledge, and social positions predicted individual’s local opinion leadership in the retweet network of popular organ donation messages. Alternatively, personal attributes and social positions, but not professional knowledge, were significantly associated with global opinion leadership. Conclusions The findings of this study indicate that health campaign designers may recruit peer leaders in SNS organ donation promotions to facilitate information sharing among the target audience. Users who are unverified, active, well connected, and experienced with information and communications technology (ICT) will accelerate the sharing of organ donation messages in the global environment.

    Wild, W.; Markus, B.; Dietrich, T.; Schmitt Glaeser, W.

    1977-01-01

    The lectures printed here, partly in revised form, were given at a University meeting for teachers in adult education on July 9th and 10th 1976 in Bayreuth, with the main theme of 'Adult education as information and help in forming opinions shown from the subject of nuclear power'. It should be shown by examples related to this problem, which urgently requires more objectivity, and which will be freed of emotional opinions with extraordinary difficulty, how complex such objects can be and how many different aspects have to be taken into account. The grouping of scientific referees, a teacher, a nuclear physicist, a radiation biologist and a lawyer, makes the plurality of the aspects quite clear. Themes: 1) The contribution of adult education to de-idealogising the population, 2) The scientific and technical basis of generation and use of nuclear power, 3)Radiation stresses of living organismus, particularly human being. 4) Smug authorities, protesting citizens, overload judges.

    2010-01-01

    Full Text Available This essay analyses the asymmetrical relationship between the time of scientific research and the time of the different segments interested in their results, focusing mainly on necessity to establish technical consensus about the fields of science that require rigorous investigations and texts. In the last years, civil society sectors - mainly scientific journalism, legislative power, and public opinion - has shown growing interest in participating of the decision making process that regulates science routes. In this study, we analyzed the decision making process of the Biosafety Law, as it allows research with embryonic stem cells in Brazil. The results allow us to conclude that this asymmetrical relationship between the different times (of science, scientific disclosure, public opinion, and public power contribute to the maturing of the dialog on scientific policies, as well as to the establishment of a consensus concerning science routes, which aims at the democratization of scientific work.

    Full Text Available Currently, two anthropological models are dominant in Romania. The first is the atheistic-evolutionary model and the second is the Christian model. The purpose of this article is to assess the students’ opinion on the two anthropological models and, in particular, on the purpose of human life. To that effect, there have been used the coefficients of association between the main aspects of the two models. Starting from the two outlined approaches, this paper aims to investigate the opinions of the students from two different specializations within Ovidius University of Constanta – the Faculty of Economics and the Faculty of Theology – on the issues mentioned above

    International Nuclear Information System (INIS)

    Arts, F.; Klaassen, R.; De Ruiter, W.

    1994-01-01

    The public opinion in the Netherlands about nuclear energy has been rather stable during recent years. Since the Chernobyl accident roughly 60% of the Dutch population is opposed to extension of the use of nuclear energy. Nuclear experts play an important role in the formation of public opinion about nuclear energy. In this paper the social and cultural background of 87 Dutch nuclear energy experts is analyzed with respect to religious belief, age, life style, membership of a political party, birth order and career pattern. 2 figs., 2 tabs., 16 refs

    Bordogna, C. M.; Albano, E. V.

    2007-04-01

    A model for opinion formation based on the Theory of Social Impact is presented and studied by means of numerical simulations. Individuals with two states of opinion are impacted due to social interactions with: i) members of the society, ii) a strong leader with a well-defined opinion and iii) the mass media that could either support or compete with the leader. Due to that competition, the average opinion of the social group exhibits phase-transition like behaviour between different states of opinion.

    This paper examines countervailing South African public opinion on the subject of prostitution in South Africa, and identifies the factors which might influence these attitudes. It also investigates the complex relationship between public opinion and the law. Whilst engaging in prostitution constitutes a criminal offence under the Sexual Offences Act 23 of 1957, it is generally ignored by the police, which results in a quasi-legalised reality on the ground. In recent years there has been grow...

    This paper shows examples of technical assistance programmes within bilateral cooperation agreements between the Federal Republic of Germany and a number of developing countries of very different characteristics and summarizes the possibilities of technical assistance granted by international organizations, such as IAEA, UNDP, etc. A basic requirement for a successful transfer of technology is a high knowledge level of the indigenous scientists and engineers. Therefore, programmes for training and education and for information exchange are presented. Based on these, the means and methods of planning, performance and quality assurance are explained by practical examples and are related to the progress achieved in the use of nuclear energy and in establishing a national industry in the developing countries.

With the offset in system theory the predominant understanding of modularity however faces difficulties in explaining the social...... dimension of modularity like irrational behaviors, cultural differences, learning processes, social organization and institutional influences on modularity. The paper addresses this gab offering a reinterpretation of the modularity concept from a socio-technical perspective in general and Actor Network...... Theory in particular. By formulating modularity from an ANT perspective covering social, material and process aspects, the modularity of a socio-technical system can be understood as an entanglement of product, process, organizational and institutional modularity.

  13. Non-consensus Opinion Models on Complex Networks

    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

    2015-09-01

    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.

  15. 2003/04 public opinion survey Nuclear energy - the present and the future

    Trontl, K.

    2004-01-01

    During the academic years 2000/01, 2001/02 and 2002/03 the Croatian Nuclear Society Young Generation Network (CYGN) carried out public opinion surveys among student population of around 600 individuals age 18-20. The results of the surveys have shown that the participants are rather ignorant on nuclear issues but still very negative, especially towards nuclear power plants and radioactive waste disposal sites with emphasized Not In My Back Yard (NIMBY) syndrome. As a part of the active involvement of CYGN members in upgrading of the positive public opinion, especially, young generations towards nuclear issues, a brochure on radioactivity has been prepared and distributed at the beginning of the 2002/03 school year to third and fourth graders in high schools. Hopefully a part of the 2003/04 academic year, freshman student population received a brochure during their high school education. Therefore, CYGN decided to carry out 2003/04 public opinion survey Nuclear Energy - the Present and the Future in order to investigate the effects of the brochure on student opinions on nuclear subjects. The results of the survey should also provide information on the quality of the distributed materials, as well as the quality of the distribution strategy. The results and the analyses of the 2003/04 public opinion survey, as well as the comparison of the results with the previous surveys are presented in this paper.(author)

  16. Breaking The Traditional Communication Flow: Exploration of Social Media Opinion Leaders in Health

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Opinion leaders play an important role in mitigating health issues and are able to influence attitudes and health behaviors to a certain extent. However, in the world we are living today, individual health decision making no longer rely fully on doctor’s advice, but often persuaded by people or organisations deemed reliable and trustworthy. Interestingly, one does not have to have a medical degree to be seen as “reliable” or “trustworthy” in giving out medical advices. Computer-mediated-communication changes the way opinion leaders emerge in virtual communities, specifically in the context of health. Through increased access to both traditional and online media, people have a fair access to communication technology and therefore, our definition of opinion leaders have shifted from how we used to understand it through Lazarsfeld’s two-steps flow theory. In fact, the way opinion leaders operate via social media platform is very different from how it used to be through the traditional mass media. This paper will discuss on the characteristics of new media opinion leaders, particularly in the context of health, in hopes to learn new ways to promote health in future communication campaigns.

      UXC + detectors As explained in detail in the November 2011 bulletin, the bellows unit at −18.5 m from the CMS interaction point was identified as a prime candidate for the regularly occurring pressure spikes which occasionally led to sustained severe background conditions in 2011, affecting dead time and data quality. Similar regions in LHC with vacuum instabilities were observed to be close to bellows, which radiography showed to have distorted RF-fingers — on removal, they proved to have been severely overheated. The plans for the Year-End Technical Stop were adapted to prioritise radiography of the bellows at 16 m to 18 m either end of CMS. Excellent work by the beam pipe, survey and heavy mechanical teams allowed the X-rays to be taken as planned on 20th December, showing that the bellow at −18.5m had an obvious non-conformity. The RF-fingers were found inside the end of the opposing flared pipe instead of outside. In addition, the overlap between fingers and...

    2013-01-01

    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 was only 5%.

    2018-05-01

    As the transmission of public opinion on the Internet in the “We the Media” era tends to be supraterritorial, concealed and complex, the traditional “point-to-surface” transmission of information has been transformed into “point-to-point” reciprocal transmission. A foundation for studies of the evolution of public opinion and its transmission on the Internet in the “We the Media” era can be laid by converting the massive amounts of fragmented information on public opinion that exists on “We the Media” platforms into structurally complex networks of information. This paper describes studies of structurally complex network-based modeling of public opinion on the Internet in the “We the Media” era from the perspective of the development and evolution of complex networks. The progress that has been made in research projects relevant to the structural modeling of public opinion on the Internet is comprehensively summarized. The review considers aspects such as regular grid-based modeling of the rules that describe the propagation of public opinion on the Internet in the “We the Media” era, social network modeling, dynamic network modeling, and supernetwork modeling. Moreover, an outlook for future studies that address complex network-based modeling of public opinion on the Internet is put forward as a summary from the perspective of modeling conducted using the techniques mentioned above.

  3. Risk perception: expert opinion versus public understanding

    International Nuclear Information System (INIS)

    Brown, Jennifer

    1987-01-01

    A research project looking at the public's attitudes towards the siting of radioactive waste depositories is reported. The risk perception studies seek to compare expert and lay understanding of risk. Adverse public reactions to risk can only be understood if it is known how people relate to risks in their everyday or working lives. Social trends and experiences are important, for example, the adverse public opinion on the siting of nuclear waste facilities. A number of elements have been identified as common to different risk areas such as chemicals, drugs, food or radioactive waste. These are the clashing of values, polarization of beliefs or clashes of interest. (UK)

    Full Text Available According to public opinion the increasing number of foreign population has became one of the most problematic issues in the last decade. Since 2005 immigration is the second biggest concern for Spaniards after unemployment and followed by terrorism. It is has became a state issue and a central government worry of utmost importance. The media coverage given to immigration is very important, specifically the way in which it is approached and presented to the readers. This paper shows the different perspectives or frames used by two key nationwide Spanish newspapers, El País y El Mundo, to cover one of the migration crises that took place in the Canary Islands in spring 2006. Following Framing theory, media content has been analyzed using variables to show the different ways in which these media depict the phenomenon of migration and the approach which each newspaper follows.

    Public information is one of the permanent activities of the Nuclear Training Centre Milan Copic at Jozef Stefan Institute in Ljubljana. It is focused on youngsters from elementary and high schools in Slovenia that visit the Centre as organized groups. Every year in the spring since 1993 some 800 youngsters are polled with basically the same set of questions inquiring about their knowledge and opinions on nuclear energy. Polling is performed at the beginning of the visit to obtain results based on information from everyday life. In the paper the results of this year's poll are presented and compared with the previous years. The attitude towards NPP Krsko is still favourable but the support has unexpectedly dropped from 83% to 73%. Misconceptions about dangers of nuclear energy and radioactive waste still remain high.

    The paper presents and discusses the results of a survey on public opinion and resident's concerns, perceptions and attitude toward MSW plants. The study was developed by means of a structured questionnaire designed on literature reviews and experiences. The study area regards four villages in a province of Naples in Campagna Region, in Southern Italy (Tufino, Comiziano, Casamarciano and Visciano). In this area there were two sanitary landfills (in their capping phase) and an RDF production plant. People in the village where MSW plants were localised, showed a 'particular' behaviour: they underestimated environmental impacts of MSW facilities. While, the results obtained from the other three villages confirmed that concerns, perceptions and attitudes towards MSW facilities are distance related [it

    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

    HM Nuclear Installations Inspectorate (HMNII) is the regulator responsible for the safety of licensed nuclear sites in the UK. Recognizing the need for public approval on future policy with respect to nuclear waste management, the NII commissioned a public opinion research programme amongst the UK general public. Opinion was sought on a number of issues including attitudes towards the industry in general, perception of nuclear waste and its management, tolerability of risk and attitudes towards current decommissioning plans. In response to the primary objectives of the survey the main findings are: current spontaneous level of concern over the industry in general is low (7%), and lower still for nuclear waste (3%). However, on prompting, 47% of respondents were very concerned about nuclear waste. Top of mind issues of concern about the industry are: nuclear waste; risk of accidents; health risks. Personal risk from nuclear waste is not of overt concern and is significantly less worrisome to respondents than risk from diseases like meningitis or cancer, smoking or road accidents. On being presented with a statement describing current UK decommissioning plans, the sample was generally in favour. However, this issue will require further research. (authors)

  15. Urban Sloths: Public Knowledge, Opinions, and Interactions

    Full Text Available Free-range sloths living in an urban environment are rare. In this study, the opinions, attitudes, and interactions with a population of Bradypus variegatus were investigated through short, structured interviews of people in the pubic square where the sloths live, in addition to informal, opportunistic observations of human-sloth interactions. A questionnaire was applied to people in the square where the sloths reside, and informal, opportunistic observations of human-sloth interactions were made. 95% of respondents knew of the sloths’ existence in the square and 87.8% liked their presence. Opinions about population size differed greatly and younger people were concerned as to whether the square was an appropriate place for them. Some human-sloth interactions showed the consequences of a lack of biological knowledge. People initiated all sloth-human interactions. The fact that sloths are strictly folivorous has avoided interactions with humans and, consequently, mitigated any negative impacts of the human-animal interaction on their wellbeing. These results demonstrate that, while there is a harmonious relationship between people and sloths, actions in environmental education of the square’s public could be beneficial for the sloths.

    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.

    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.
