    A pooling of strong motion data held by ENEA (Rome), Imperial College (London) and CEA/IPSN (Paris) will, in the future, give rise to a unified set of data, accessible from any one of the three centers, composed of a data bank of uncorrected accelerograms associated with an accessory data base containing as ample information as possible concerning the earthquake itself and the recording conditions. All three centers are equipped with VAX computer material, and a DECNET link is currently under consideration. The data thus structured is destined to form the basis of a European strong-motion data bank [fr

    PUBLIC SUPPORT FOR HEALTH REFORM: Findings from the 2009 Health Confidence Survey--the 12th annual HCS--indicate that Americans have already formed strong opinions regarding various aspects of health reform, even before details have been released regarding various key factors. These issues include health insurance market reform, the availability of a public plan option, mandates on employers and individuals, subsidized coverage for the low-income population, changes to the tax treatment of job-based health benefits, and regulatory oversight of health care. These opinions may change as details surface, especially as they concern financing options. In the absence of such details, the 2009 HCS finds generally strong support for the concepts of health reform options that are currently on the table. U.S. HEALTH SYSTEM GETS POOR MARKS, BUT SO DOES A MAJOR OVERHAUL: A majority rate the nation's health care system as fair (30 percent) or poor (29 percent). Only a small minority rate it excellent (6 percent) or very good (10 percent). While 14 percent of Americans think the health care system needs a major overhaul, 51 percent agree with the statement "there are some good things about our health care system, but major changes are needed." NATIONAL HEALTH PLAN ELEMENTS RATED HIGHLY: Between 68 percent and 88 percent of Americans either strongly or somewhat support health reform ideas such as national health plans, a public plan option, guaranteed issue, expansion of Medicare and Medicaid, and employer and individual mandates. MIXED REACTION TO HEALTH BENEFITS TAX CAP: Reaction to capping the current tax exclusion of employment-based health benefits is mixed. Nearly one-half of Americans (47 percent) would switch to a lower-cost plan if the tax exclusion were capped, 38 percent would stay on their current plan and pay the additional taxes, and 9 percent don't know.

    Opinions are rarely binary; they can be held with different degrees of conviction, and this expanded attitude spectrum can affect the influence one opinion has on others. Our goal is to understand how different aspects of influence lead to recognizable spatio-temporal patterns of opinions and their strengths. To do this, we introduce a stochastic spatial agent-based model of opinion dynamics that includes a spectrum of opinion strengths and various possible rules for how the opinion strength of one individual affects the influence that this individual has on others. Through simulations, we find that even a small amount of amplification of opinion strength through interaction with like-minded neighbors can tip the scales in favor of polarization and deadlock.

    We introduce an inflexible contrarian opinion (ICO) model in which a fraction p of inflexible contrarians within a group holds a strong opinion opposite to the opinion held by the rest of the group. At the initial stage, stable clusters of two opinions, A and B, exist. Then we introduce inflexible contrarians which hold a strong B opinion into the opinion A group. Through their interactions, the inflexible contrarians are able to decrease the size of the largest A opinion cluster and even destroy it. We see this kind of method in operation, e.g., when companies send free new products to potential customers in order to convince them to adopt their products and influence others to buy them. We study the ICO model, using two different strategies, on both Erdös-Rényi and scale-free networks. In strategy I, the inflexible contrarians are positioned at random. In strategy II, the inflexible contrarians are chosen to be the highest-degree nodes. We find that for both strategies the size of the largest A cluster decreases to 0 as p increases as in a phase transition. At a critical threshold value, p(c), the system undergoes a second-order phase transition that belongs to the same universality class of mean-field percolation. We find that even for an Erdös-Rényi type model, where the degrees of the nodes are not so distinct, strategy II is significantly more effective in reducing the size of the largest A opinion cluster and, at very small values of p, the largest A opinion cluster is destroyed.

  10. Student opinion formation on animal agriculture issues.

    Walter, G; Reisner, A

    1994-06-01

    Agriculture and animal science student bodies are shifting toward a more urban composition at the same time that criticism of animal industries by nonagricultural groups is increasing. Animal science classes include students with diverse educational goals, agricultural knowledge and experience, and values. Students without agricultural backgrounds or who have not formed opinions on agricultural questions may lack the integrated knowledge that motivates them to seek, organize, and retain the technical subject matter presented in their animal science courses. A survey of undergraduates in animal science and other agriculture majors indicates that significant numbers are unable or unwilling to offer opinions on questions related to critical social issues facing animal agriculture. Opinion holding among animal science majors and non-majors was relatively similar. However, students from urban backgrounds were less likely than rural students to offer opinions, and many of those who offered opinions held views different from those of students from rural backgrounds. Students reporting recent exposure to the issue in their academic course work were somewhat more likely to hold opinions. The findings are consistent with a social-psychological learning model that suggests instructors should require students to express and defend positions on agricultural issues in course activities.

  11. Reinforcement in opinion dynamics

    Science.gov (United States)

    Volovik, Daniel

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

    The American sociologist Charles Horton Cooley defined public opinion "as a process of interaction and mutual influence rather than a state of broad agreement" in 1918. On the other hand, according to the American political scientist V.O. Key, public opinion was "opinions held by private persons which governments find it prudent to heed," in 1961. During the 1990s, advances in statistical and demographic analysis helped the development of an understanding of public opinion as the collective v...

  13. Discrepancy and Disliking Do Not Induce Negative Opinion Shifts.

    Science.gov (United States)

    Takács, Károly; 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.

    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 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.

    There is widespread conviction among the professionals working in the nuclear sector that the image of nuclear energy held by the general public is poor. In Spain we insist again and again that an overwhelming majority of people consider nuclear energy to be dangerous, contaminating and relating to war. Depending on individual experience, we even go as far as to venture percentages of acceptability. When asked to explain the reasons for this, some claim that the cause of this attitude of rejection is to do with wastes, others that it is fear of radiation, and so on. Most of these claims are 'subjective perceptions' based on our own personal contacts and xperiences. With a view to establishing a reliable analytical basis and thus be able to carry out an objective study of the problem of public perception of nuclear energy in Spain, the Forum of the Spanish Nuclear Industry commissioned a group of external consultants specializing in this type of studies to carry out a survey designed to provide information on the causes underlying the rejection of nuclear energy and its measure. This survey is one of the first performed in this country since the decision was taken to use nuclear power in the nineteen sixties. The survey, performed by way of telephone conversations, included 2,000 people aged between 15 and 60 years. Of the total number of interviewees, 25 percent lived in areas surrounding a nuclear power plant, but had no direct professional or family ties with the plant. In addition to the 2000 telephone interviews, the study included also a qualitative investigation based on open interviews and focus groups. In general, the image detected during the qualitative phase is that in spite of its being technologically advanced and professionally directed and managed, nuclear energy arouses fear and mistrust. The structure of the survey was based on overall issues: the concerns of Spanish society. Twenty-four percent of the interviewees claimed that the environment was

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

  3. Are extinction opinions extinct?

    Tamsin E. Lee

    2017-08-01

    Full Text Available Extinction models vary in the information they require, the simplest considering the rate of certain sightings only. More complicated methods include uncertain sightings and allow for variation in the reliability of uncertain sightings. Generally extinction models require expert opinion, either as a prior belief that a species is extinct, or to establish the quality of a sighting record, or both. Is this subjectivity necessary? We present two models to explore whether the individual quality of sightings, judged by experts, is strongly informative of the probability of extinction: the ‘quality breakpoint method’ and the ‘quality as variance method’. For the first method we use the Barbary lion as an exemplar. For the second method we use the Barbary lion, Alaotra grebe, Jamaican petrel and Pohnpei starling as exemplars. The ‘quality breakpoint method’ uses certain and uncertain sighting records, and the quality of uncertain records, to establish whether a change point in the rate of sightings can be established using a simultaneous Bayesian optimisation with a non-informative prior. For the Barbary lion, there is a change in subjective quality of sightings around 1930. Unexpectedly sighting quality increases after this date. This suggests that including quality scores from experts can lead to irregular effects and may not offer reliable results. As an alternative, we use quality as a measure of variance around the sightings, not a change in quality. This leads to predictions with larger standard deviations, however the results remain consistent across any prior belief of extinction. Nonetheless, replacing actual quality scores with random quality scores showed little difference, inferring that the quality scores from experts are superfluous. Therefore, we deem the expensive process of obtaining pooled expert estimates as unnecessary, and even when used we recommend that sighting data should have minimal input from experts in terms of

    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)

    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.

The opinion of each agent can have integer values i = 1, 2, ..., I and opinion exchanges are restricted to connected agents. It was found that for any I {>=} 2 and self-confidence parameter 0 {<=} u < 1, when u is a degree-independent constant, the weighted proportion (q{sub i}) of the population that hold a given opinion i is a martingale, and the fraction q{sub i} of opinion i will gradually converge to (q{sub i}). The tendency can slow down with the increase of degree assortativity of networks. When u is degree dependent, (q{sub i}) does not possess the martingale property, however q{sub i} still converges to it. In both cases for a finite network the states of all agents will finally reach consensus. Further if there exist stubborn persons in the population whose opinions do not change over time, it was found that for degree-independent constant u, both q{sub i} and (q{sub i}) will converge to fixed proportions which only depend on the distribution of initial obstinate persons, and naturally the final equilibrium state will be the coexistence of diverse opinions held by the stubborn people.

  12. Opinion Formation by Social Influence: From Experiments to Modeling.

    2015-01-01

    Predicting different forms of collective behavior in human populations, as the outcome of individual attitudes and their mutual influence, is a question of major interest in social sciences. In particular, processes of opinion formation have been theoretically modeled on the basis of a formal similarity with the dynamics of certain physical systems, giving rise to an extensive collection of mathematical models amenable to numerical simulation or even to exact solution. Empirical ground for these models is however largely missing, which confine them to the level of mere metaphors of the real phenomena they aim at explaining. In this paper we present results of an experiment which quantifies the change in the opinions given by a subject on a set of specific matters under the influence of others. The setup is a variant of a recently proposed experiment, where the subject's confidence on his or her opinion was evaluated as well. In our realization, which records the quantitative answers of 85 subjects to 20 questions before and after an influence event, the focus is put on characterizing the change in answers and confidence induced by such influence. Similarities and differences with the previous version of the experiment are highlighted. We find that confidence changes are to a large extent independent of any other recorded quantity, while opinion changes are strongly modulated by the original confidence. On the other hand, opinion changes are not influenced by the initial difference with the reference opinion. The typical time scales on which opinion varies are moreover substantially longer than those of confidence change. Experimental results are then used to estimate parameters for a dynamical agent-based model of opinion formation in a large population. In the context of the model, we study the convergence to full consensus and the effect of opinion leaders on the collective distribution of opinions.

    Full Text Available Opinion mining is an emerging field which uses methods of natural language processing, text mining and computational linguistics to extract subjective information of opinion holders. Opinion mining can be viewed as a classification problem. Hence, machine learning based methods are widely employed for sentiment classification. Machine learning based methods in opinion mining can be mainly classified as supervised, semi-supervised and unsupervised methods. In this study, main existing literature on the use of machine learning methods for opinion mining has been presented. Besides, the weak and strong characteristics of machine learning methods have been discussed.

    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

  18. Zealotry effects on opinion dynamics in the adaptive voter model

    2017-11-01

    The adaptive voter model has been widely studied as a conceptual model for opinion formation processes on time-evolving social networks. Past studies on the effect of zealots, i.e., nodes aiming to spread their fixed opinion throughout the system, only considered the voter model on a static network. Here we extend the study of zealotry to the case of an adaptive network topology co-evolving with the state of the nodes and investigate opinion spreading induced by zealots depending on their initial density and connectedness. Numerical simulations reveal that below the fragmentation threshold a low density of zealots is sufficient to spread their opinion to the whole network. Beyond the transition point, zealots must exhibit an increased degree as compared to ordinary nodes for an efficient spreading of their opinion. We verify the numerical findings using a mean-field approximation of the model yielding a low-dimensional set of coupled ordinary differential equations. Our results imply that the spreading of the zealots' opinion in the adaptive voter model is strongly dependent on the link rewiring probability and the average degree of normal nodes in comparison with that of the zealots. In order to avoid a complete dominance of the zealots' opinion, there are two possible strategies for the remaining nodes: adjusting the probability of rewiring and/or the number of connections with other nodes, respectively.

  19. Opinion dynamics with confirmation bias.

    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.

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.

  1. Phase Transitions in a Social Impact Model for Opinion Formation

    Science.gov (United States)

    Bordogna, Clelia M.; Albano, Ezequiel V.

    A model for opinion formation in a social group, based on the Theory of Social Impact developed by Latané, is studied by means of numerical simulations. Interactions among the members of the group, as well as with a strong leader competing with the mass media, are considered. The model exhibits first-order transitions between two different states of opinion, which are supported by the leader and the mass media, respectively. The social inertia of the group becomes evident when the opinion of the leader changes periodically. In this case two dynamic states are identified: for long periods of time, the group follows the changes of the leader but, decreasing the period, the opinion of the group remains unchanged. This scenery is suitable for the ocurrence of dynamic phase transitions.

    Currently two paradigms seek to explain how voters change their opinion when they are confronted with new information. One school argues that voters are bayesian updaters who rationally change their opinion. Another school argues that voters are inherently biased in their evaluation of new...... information. 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. Using a quasi experiment we investigate the extent to which voters rely on bayesian updating or on motivated reasoning when...

    The misleading statements made in the British Dental Journal in the December 2016 issue relating to dental age assessment are assessed for inaccuracies and negligent omission of the issue of Child Protection. It is emphasised that there is a need for the approach of objective knowledge viz. not influenced by personal feelings or opinions in considering and representing facts. The article by the Chair of the Education, Ethics, and Team Working Group implies that unsatisfactory consent procedures are followed. The DARLInG (Dental Age Research London Information Group) have followed a carefully prescribed procedure that fulfils all the requirements of the advice given by the Consent Committee at King's College Hospital. In addition, the active support in the form of independent support workers and lawyers assisted by interpreters is described. The issue of the lawful use of ionising radiation is described with correct information about where this information can be obtained. The seriously misleading statements made by the Chair of the Education, Ethics and Education Working Group are identified. An unacceptable oversight is the failure of the BDA representatives to draw attention to the need for child protection. The potential benefit of dental age estimation in terms of appropriately providing support for asylum seekers is described.The failure of the BDA Ethics group to be up to date with recent research which shows a high level of certainty in assigning age disputed subjects to above (or below) the 18-year threshold is discussed and the importance of this in reliably determining, in an objective way, the age status of asylum seekers. The incorrect and salacious use of the term 'X-rated' is highlighted and a formal request for its withdrawal has been made.

    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.

  5. Social influence and the collective dynamics of opinion formation.

    Social influence is the process by which individuals adapt their opinion, revise their beliefs, or change their behavior as a result of social interactions with other people. In our strongly interconnected society, social influence plays a prominent role in many self-organized phenomena such as herding in cultural markets, the spread of ideas and innovations, and the amplification of fears during epidemics. Yet, the mechanisms of opinion formation remain poorly understood, and existing physics-based models lack systematic empirical validation. Here, we report two controlled experiments showing how participants answering factual questions revise their initial judgments after being exposed to the opinion and confidence level of others. Based on the observation of 59 experimental subjects exposed to peer-opinion for 15 different items, we draw an influence map that describes the strength of peer influence during interactions. A simple process model derived from our observations demonstrates how opinions in a group of interacting people can converge or split over repeated interactions. In particular, we identify two major attractors of opinion: (i) the expert effect, induced by the presence of a highly confident individual in the group, and (ii) the majority effect, caused by the presence of a critical mass of laypeople sharing similar opinions. Additional simulations reveal the existence of a tipping point at which one attractor will dominate over the other, driving collective opinion in a given direction. These findings have implications for understanding the mechanisms of public opinion formation and managing conflicting situations in which self-confident and better informed minorities challenge the views of a large uninformed majority.

    Messages conveyed by media act as a major drive in shaping attitudes and inducing opinion shift. On the other hand, individuals are strongly affected by peer pressure while forming their own judgment. We solve a general model of opinion dynamics where individuals either hold one of two alternative opinions or are undecided and interact pairwise while exposed to an external influence. As media pressure increases, the system moves from pluralism to global consensus; four distinct classes of collective behavior emerge, crucially depending on the outcome of direct interactions among individuals holding opposite opinions. Observed nontrivial behaviors include hysteretic phenomena and resilience of minority opinions. Notably, consensus could be unachievable even when media and microscopic interactions are biased in favor of the same opinion: The unfavored opinion might even gain the support of the majority.

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

    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.

    The Japanese National Survey on Family Planning has been conducted since 1950 by the Mainichi Newspapers. The 21st survey, which included approximately 3400 persons, was conducted in 1992 in conjunction with various family planning organizations. The results reported include the ideal number of children, care for the elderly, tolerance for induced abortion, beliefs about the side effects of oral contraceptives, attitudes of husbands toward their wives working outside the home, sexual harassment, and elderly husband's concern about contracting AIDS. 45% of respondents supported Japan's involvement in FP efforts in developing countries, and 20.9% disapproved of involvement. Fertility declined from 1.54 in 1990 to 1.53 in 1991. There was an 5% increase to 75.3% in the number of women concerned about declining fertility for such reasons as the loss of social vitality and the increased burden of support in old age. However, 60.9% of wives and 56.8% of husbands felt that the government should not take action to prevent further fertility decline. Public policies for reducing the cost of education were supported by 39.6% of wives and 43.6% of husbands. A similar number supported increases in child allowance, and a smaller percentage of husbands and wives wanted the government to subsidize housing expenses. The ideal number of children was 3 for 45.7% of those surveyed, which was more than those desiring 2 children. The ideal of 3 children was held by survey participants who were more than 35 years old and by those with a high education. Part-time workers and office clerks were more likely to report that 2 children were ideal. An increasing number of respondents (60.4%) do not intend to rely on their children in old age. There has been a shift in family planning methods from induced abortions to increased contraceptive use. The highest rate of contraceptive use is among wives 35-39 years old. 75.3% use condoms. 67.7% reported concern about side effects from oral

    'Strong conformity' corresponds to the public endorsement of majority opinions that are in blatant contradiction to one's own correct perceptual judgements of the situation. We tested strong conformity inference by 3- and 5-year-old children using a third-person perspective paradigm. Results show that at neither age, children spontaneously expect that an ostracized third-party individual who wants to affiliate with the majority group will show strong conformity. However, when questioned as to what the ostracized individual should do to befriend others, from 5 years of age children explicitly demonstrate that they construe strong conformity as a strategic means of social affiliation. Additional data suggest that strong and strategic conformity understanding from an observer's third-person perspective is linked to the passing of the language-mediated false belief theory of mind task, an index of children's emerging 'meta' ability to construe the mental state of others. Statement of contribution What is already known on this subject? 'Strong conformity' corresponds to the public endorsement of majority opinions that are in blatant contradiction to one's own correct perceptual judgements of the situation. Asch's (1956, Psychological Monographs: General and Applied, 70, 1) classic demonstration of strong conformity with adults has been replicated with preschool children: 3- to 4-year-olds manifest signs of strong conformity by reversing about thirty to forty per cent of the time their correct perceptual judgements to fit with contradictory statements held unanimously by other individuals (Corriveau & Harris, 2010, Developmental Psychology, 46, 437; Corriveau et al., 2013, Journal of Cognition and Culture, 13, 367; Haun & Tomasello, 2011, Child Development, 82, 1759). As for adults, strong conformity does not obliterate children's own private, accurate knowledge of the situation. It is in essence a public expression to fit the group and alleviate social dissonance

    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

    2017-12-01

    Experts in criminal, civil and, increasingly, in social court cases have to present their expert opinions in court. This should be regarded not only as a burden, even if this may at times appear superfluous to the expert, perhaps because the discussion is mere repetition of the opinion he has already written, or because the questions appear to be biased against the expert. Nonetheless, the expert is always advised to appear calm and objective during the interrogation by judges and parties or participants and their legal representatives, and should not allow himself or herself to be provoked by questioning. Furthermore, it may be necessary to correct the written expert statement in the course of the interrogation, but this can be a sign of a truly competent medical expert. The expert consulted can be held liable for adverse health effects resulting from the interrogation and investigation, as well as for deliberate or grossly faulty reports.

    2018-01-01

    Public opinion can be an influential factor in wildlife management decisions. Evaluating public opinions can help legitimize, or delegitimize, management and facilitate long-term conservation goals. This is especially true for the controversial issues surrounding the management of predators. We surveyed Montana, USA, residents during summer of 2013 to measure public opinion regarding economic and ecological impacts of the gray wolf (Canis lupus), and current management of this species. Although opinions were polarized in some areas, a greater percentage of Montanans think that wolves negatively affect the economy, but impact tourism (which contributes to the economy) positively. These differences may reflect the belief that rancher economic losses from wolf predation of cattle is greater than overall tourism gains related to wolves (e.g., wolf-watching), in addition to the perception of wolves negatively affecting big game (e.g., elk [Cervus canadensis]). Results also show that a slightly greater percentage of Montanans feel that wolves positively rather than negatively affect the ecosystem. Regarding specific practices, more Montanans than not have a positive opinion of maintaining wolves on the landscape and also support hunting of wolves. More Montanans hold negative rather than positive opinions, however, regarding wolf trapping. This result was most evident in western Montana as assessed by a spatial distribution of opinions by county and has implications for current wolf management and nontarget species. Results of ordinal regression analyses revealed that big game hunters, males, and those who held negative opinions of the effect of wolves on the Montana ecosystem and economy were significantly more likely to support both hunting and trapping practices. Living in western Montana predicted positive opinions of hunting, but alternatively, negative opinions of trapping. These results provide an understanding of public opinion of wolf management by county as

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

  1. Hand-held medical robots.

    Science.gov (United States)

    Payne, Christopher J; Yang, Guang-Zhong

    2014-08-01

    Medical robots have evolved from autonomous systems to tele-operated platforms and mechanically-grounded, cooperatively-controlled robots. Whilst these approaches have seen both commercial and clinical success, uptake of these robots remains moderate because of their high cost, large physical footprint and long setup times. More recently, researchers have moved toward developing hand-held robots that are completely ungrounded and manipulated by surgeons in free space, in a similar manner to how conventional instruments are handled. These devices provide specific functions that assist the surgeon in accomplishing tasks that are otherwise challenging with manual manipulation. Hand-held robots have the advantages of being compact and easily integrated into the normal surgical workflow since there is typically little or no setup time. Hand-held devices can also have a significantly reduced cost to healthcare providers as they do not necessitate the complex, multi degree-of-freedom linkages that grounded robots require. However, the development of such devices is faced with many technical challenges, including miniaturization, cost and sterility, control stability, inertial and gravity compensation and robust instrument tracking. This review presents the emerging technical trends in hand-held medical robots and future development opportunities for promoting their wider clinical uptake.

  2. Public opinion on Fukushima Daiichi nuclear disaster

    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

    2007-12-01

    The dynamic behavior of a social group influenced by both a strong leader and the mass media, which is modeled according to the social impact theory, is studied under two situations: (i) The strong leader changes his/her state of opinion periodically while the mass media are not considered. In this case, the leader is capable of driving the group between a dynamically ordered state with a weak leader-group coupling (high-frequency regime) and a dynamically disordered state where the group follows the opinion of the leader (low-frequency regime). (ii) The mass-media change periodically their message and have to compete with a strong leader that keeps his/her state of opinion unchanged. In this case, the mass media require an amplitude threshold in order to overcome the influence of the leader and drive the system into a dynamically disordered state. The dynamic behavior characteristic of the studied social opinion model shares many features of physical systems that are relevant in the fields of statistical mechanics and condensed matter.

    2001-01-01

    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)

  9. Conformity to the opinions of other people lasts for no more than 3 days.

    2014-07-01

    When people are faced with opinions different from their own, they often revise their own opinions to match those held by other people. This is known as the social-conformity effect. Although the immediate impact of social influence on people's decision making is well established, it is unclear whether this reflects a transient capitulation to public opinion or a more enduring change in privately held views. In an experiment using a facial-attractiveness rating task, we asked participants to rate each face; after providing their rating, they were informed of the rating given by a peer group. They then rerated the same faces after 1, 3, or 7 days or 3 months. Results show that individuals' initial judgments are altered by the differing opinions of other people for no more than 3 days. Our findings suggest that because the social-conformity effect lasts several days, it reflects a short-term change in privately held views rather than a transient public compliance. © The Author(s) 2014.

  10. Public opinion on childhood immunisations in Iceland.

    In recent years, vaccine preventable diseases such as measles and pertussis have been re-emerging in Western countries, maybe because of decreasing participation in childhood vaccination programs in some countries. There is clear evidence for vaccine efficacy and the risk of adverse effects is low. This needs to be communicated to the general public. The aim of the study was to evaluate the public opinion on childhood vaccinations in Iceland. An internet based study was used to evaluate the opinion on childhood immunisations in Iceland. The cohort was divided in three groups: (a) general public (b) employees of the University Hospital Iceland and (c) employees (teachers and staff) of the University of Iceland. The cohorts could be stratified according to age, gender, education, household income, parenthood and residency. Responses were received from 5584 individuals (53% response rate). When asked about childhood vaccinations in the first and second year of life, approximately 95% of participants were "positive" or "very positive", approximately 1% were "negative" or "very negative". When participants were asked whether they would have their child immunized according to the Icelandic childhood vaccination schedule, 96% were "positive" or "very positive", 1.2% were "negative" or "very negative". Similarly, 92% trust Icelandic Health authorities to decide on childhood vaccination schedule, 2.3% did not. In total, 9.3% "rather" or "strongly" agreed to the statement "I fear that vaccinations can cause severe adverse effects", 17.5% were undecided and 66.9% "disagreed" or "strongly disagreed". Individuals with higher education were more likely to disagree with this statement (OR=1.45, CI95=1.29-1.64, p<0.001) as did males (OR=1.22, CI95=1.087-1.379, p=0.001). This study shows a very positive attitude towards vaccinations raising expectations for an ongoing success in preventing preventable communicable diseases in childhood in Iceland.

  12. (Miscommunication across the Borders: Politics, Media and Public Opinion in Turkey

    Directory of Open Access Journals (Sweden)

    Banu Baybars-Hawks

    2015-08-01

    Full Text Available The American sociologist Charles Horton Cooley defined public opinion "as a process of interaction and mutual influence rather than a state of broad agreement" in 1918. On the other hand, according to the American political scientist V.O. Key, public opinion was "opinions held by private persons which governments find it prudent to heed," in 1961. During the 1990s, advances in statistical and demographic analysis helped the development of an understanding of public opinion as the collective view of a defined population, such as a particular demographic or ethnic group. In this view, the influence of public opinion is not restricted to politics and elections. Public opinion is considered a powerful force in many other spheres, such as culture, fashion, literature and the arts, consumer spending, and marketing and public relations.1 Attitudes and values play a crucial role in the development of public opinion. Different variables embedded in the political, social and media structure of the country also have potential to make an impact on public opinion. These dynamics vary from the economics to the judicial system and democratic principles functioning in that country. On the other hand, public opinion has a power to shape politics and media's priorities in reporting. The interaction among politics, public opinion and media of one country can be better analyzed with the findings of public opinion research administered regularly. In Turkey, the research on and analysis of public opinion are most frequent during the election times. Therefore, it seems necessary to measure the public opinion more regularly to test the relationships among political, public and media agendas. Accordingly, the current study seeks to fill this gap. It is argued that in the absence of timely feedback from public surveys, decisions and policies for improving different services and institutions functioning in the country might not achieve their expected goal. The findings of

  1. Comparison of expert and nonexpert swimmers' opinions about the value, potency, and activity of four standard swimming strokes and underwater undulatory swimming.

    Science.gov (United States)

    Collard, L; Oboeuf, A

    2009-04-01

    Underwater undulatory swimming (UUS) is often perceived to be a nonessential aspect of aquatic propulsion. Given their solid theoretical and practical training in swimming, physical education students should be capable of judging the true value of the "fifth stroke," since it appears to be the most efficient technique in high level, competitive swimming. To compare opinions and connotations associated with the stroke and the four official strokes (butterfly, backstroke, breaststroke, and crawl), 198 students (32 of whom were expert swimmers; M age = 20.6 yr., SD = 1.2), were surveyed using the semantic differential of Osgood, Suci, and Tannenbaum. Although answers of expert and nonexpert swimmers differed significantly (p or = 1.1 with SD max = 3 for the expert swimmers) attests to the view being less strongly held by swimming specialists.

The hot event, A Female Driver Was Beaten Due To Lane Change, has characteristics of individual short-term and non-government intervention, which is used to data extraction, and formed of the network structure on opinion leaders influencing the public opinion transmission. And the evolution mechanism are analyzed in the three evolutionary situations. Opinion leaders influence micro-blogging public opinion on social network evolution model shows that this type of network public opinion transmission is largely constrained by opinion leaders, so the opinion leaders behavior supervising on the spread of this public opinion is pivotal, and which has a guiding significance.

    2010-06-01

    To analyze the opinion of judges and prosecutors concerning Brazilian abortion law and situations in which the abortion should be allowed. A cross-sectional study was performed with 1,493 judges and 2,614 prosecutors in Brazil between 2005 and 2006. Participants completed a structured questionnaire approaching sociodemographic characteristics, opinions about abortion law, and circumstances in which abortion is considered lawful. Bivariate and multivariate analyses of data were carried out through Poisson regression. The majority of participants (78%) found that the circumstances in which abortion is considered lawful should be broadened, or even that abortion should not be criminalized. The highest rates of pro-abortion opinions resulted from: risk to the life of the mother (84%), anencephaly (83%), severe congenital malformation of fetus (82%), and pregnancy resulting from rape (82%). Variables related to religion were strongly associated to the opinion of participants. There is a trend in considering the need of changing the current abortion law, in the sense of widening the circumstances in which abortion is considered lawful, or even toward decriminalizing abortion, regardless of the circumstances in which it takes place.

  19. French opinion on Nuclear Energy

    International Nuclear Information System (INIS)

    Bucaille, A.

    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

    2010-01-01

    Although the indications and surgical technique for cochlear implantation are well formalized, the introduction of hearing preservation surgery and electric acoustic stimulation have posed new questions for the cochlear implant clinician. This study was designed to crystallize the contemporary views of the implant community on how best to implement these new strategies. An anonymized questionnaire was made available to members of the Politzer Society and a selected group of implant surgeons via the Internet. Five questions required the respondent to choose a specific answer from the text on technique and 17 questions assessed the relative importance attached to the statements relating to the surgical process. A final question inquired on what basis the opinions were derived. The country of origin was also identified. The questionnaire was sent to 180 clinicians of whom 62 replied (34%). Tacit agreement was obtained in 2 of the specific questions and in 10 of the relative importance inquiries. There were varying degrees of opinions on the remaining questions. It is clear that there is still limited consensus between surgeons when considering ways of maximizing outcomes in hearing preservation surgery and electric acoustic stimulation. More protocol-driven studies are required before an accepted gold standard approach can be achieved. Copyright 2010 S. Karger AG, Basel.

  1. Opinion formation and distribution in a bounded-confidence model on various networks

    Science.gov (United States)

    Meng, X. Flora; Van Gorder, Robert A.; Porter, Mason A.

    2018-02-01

    In the social, behavioral, and economic sciences, it is important to predict which individual opinions eventually dominate in a large population, whether there will be a consensus, and how long it takes for a consensus to form. Such ideas have been studied heavily both in physics and in other disciplines, and the answers depend strongly both on how one models opinions and on the network structure on which opinions evolve. One model that was created to study consensus formation quantitatively is the Deffuant model, in which the opinion distribution of a population evolves via sequential random pairwise encounters. To consider heterogeneity of interactions in a population along with social influence, we study the Deffuant model on various network structures (deterministic synthetic networks, random synthetic networks, and social networks constructed from Facebook data). We numerically simulate the Deffuant model and conduct regression analyses to investigate the dependence of the time to reach steady states on various model parameters, including a confidence bound for opinion updates, the number of participating entities, and their willingness to compromise. We find that network structure and parameter values both have important effects on the convergence time and the number of steady-state opinion groups. For some network architectures, we observe that the relationship between the convergence time and model parameters undergoes a transition at a critical value of the confidence bound. For some networks, the steady-state opinion distribution also changes from consensus to multiple opinion groups at this critical value.

  2. Changes in alcohol policies and public opinions in Finland 2003-2013.

    There is a constant and ongoing interplay between public opinions and public policies, alcohol policies being no exception. This article describes the development of public opinions regarding alcohol policy in Finland during a 10-year period between 2003 and 2013. Fluctuations in the alcohol policy opinion climate are put in context by looking at concurrent changes in alcohol policies and in total alcohol consumption. The study is based on data from opinion surveys on alcohol policies commissioned by the National Institute for Health and Welfare and the Finnish Social and Health Association. The opinion polls include questions about the general acceptance of prevailing alcohol policies, appropriate sales channels of different alcoholic beverage categories and opinions about the legal age limits and prices of alcoholic beverages. In the study, changes in alcohol policy during 2003-2013 are surveyed, and their relationship with changes in alcohol policy opinion is examined. There seem to be a strong positive correlation during the study period between the level of alcohol consumption and the share of those wanting a more restrictive alcohol policy in Finland. It seems that an increased level of awareness of alcohol-related issues among the general public created a more restrictive opinion climate on alcohol policy issues after the big alcohol excise duty decrease in 2004. The reverse seems to happen but in a lesser degree when alcohol excise duties has been increased after the year 2007. © 2014 Australasian Professional Society on Alcohol and other Drugs.

  3. Your opinion on climate change might not be as common as you think

    2013-04-01

    Political and media debate on the existence and causes of climate change has become increasingly factious in several western countries, often resting on claims and counter-claims about what most citizens really think. There are several well-established phenomena in psychology about how people perceive the prevalence of opinions, including the false consensus effect (a tendency to overestimate how common one's `own' opinion is) and pluralistic ignorance (where most people privately reject an opinion, but assume incorrectly that most others accept it). We investigated these biases in people's opinions about the existence and causes of climate change. In two surveys conducted 12 months apart in Australia (n=5,036 n=5,030), respondents were asked their own opinion about the nature of climate change, and then asked to estimate levels of opinion among the general population. We demonstrate that opinions about climate change are subject to strong false consensus effects, that people grossly overestimate the numbers of people who reject the existence of climate change in the broader community, and that people with high false consensus bias are less likely to change their opinions.

    There is great uncertainty due to challenges of escalating population growth and climate change. Public perception that diverges from the scientific community may decrease the effectiveness of scientific inquiry and innovation as tools to solve these challenges. The objective of this study was to identify the factors associated with the divergence of public opinion from scientific consensus regarding the safety of genetically modified (GM) foods and human involvement in global warming (GW). Results indicate that the effects of knowledge on public opinion are complex and non-uniform across types of knowledge (i.e., perceived and actual) or issues. Political affiliation affects agreement with science; Democrats were more likely to agree that GM food is safe and human actions cause GW. Respondents who had relatively higher cognitive function or held illusionary correlations about GM food or GW were more likely to have an opinion that differed from the scientific community.

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.)

    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.

    1995-01-01

    The crux of the issue of spent nuclear fuel for much of the American public is that taking car of our waste now instead of leaving it for future generations is the safe and environmentally responsible think to do. This article summarizes a number of public opinion surveys. Although it is important to recognize that most people are not familiar with specifics, much of the American public has a strong opinions about the fundamental guiding principles for safely managing radioactive waste. First there is clear agreement that we need action. Second, safety means taking the waste to a permanent disposal facility instead of leaving it in many different locations. Third, most of the public would like to keep nuclear energy as a supply option. Fourth, the majority of the public agreed with the statement that the availability of nuclear energy as an option for future energy supply depends on building a national waste storage or disposal facility

    2017-11-01

    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.

    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.

    -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.

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.

  4. Political opinion polling in post-authoritarian Indonesia: Catalyst or obstacle to democratic consolidation?

    Directory of Open Access Journals (Sweden)

    Marcus Mietzner

    2009-05-01

    Full Text Available The introduction of democratic elections in Indonesia after the downfall of Soeharto’s authoritarian New Order regime in 1998 has triggered intensive scholarly debates about the competitiveness, credibility and representativeness of these ballots. The main focus of such discussions has understandably been on the primary actors in the elections – parties, individual candidates and voters. But this concentration on voting behaviour and electoral outcomes has shifted attention away from another development that is at least as significant in shaping Indonesia’s new democracy: that is, the remarkable proliferation of opinion pollsters and political consultants. The central role of opinion polls in post-Soeharto politics – and the diversity of views expressed in them – have challenged many of the conventional wisdoms held about the Indonesian electorate. The picture that emerges from the rapid spread of opinion polls in recent years, and from their profound impact on the political elite, points to an increasingly sophisticated (and diversified electorate. The rise of opinion polls as key elements in electoral politics has been so fast and so consequential that Indonesia now faces the same dilemmas typically associated with the dominance of pollsters in consolidated Western democracies. This article discusses the implications of the rising importance of opinion polling for Indonesia’s consolidating democracy.

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

    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

    2012-07-01

    This special section is dedicated to the Strongly Correlated Electron Systems Conference (SCES) 2011, which was held from 29 August-3 September 2011, in Cambridge, UK. SCES'2011 is dedicated to 100 years of superconductivity and covers a range of topics in the area of strongly correlated systems. The correlated electronic and magnetic materials featured include f-electron based heavy fermion intermetallics and d-electron based transition metal compounds. The selected papers derived from invited presentations seek to deepen our understanding of the rich physical phenomena that arise from correlation effects. The focus is on quantum phase transitions, non-Fermi liquid phenomena, quantum magnetism, unconventional superconductivity and metal-insulator transitions. Both experimental and theoretical work is presented. Based on fundamental advances in the understanding of electronic materials, much of 20th century materials physics was driven by miniaturisation and integration in the electronics industry to the current generation of nanometre scale devices. The achievements of this industry have brought unprecedented advances to society and well-being, and no doubt there is much further to go—note that this progress is founded on investments and studies in the fundamentals of condensed matter physics from more than 50 years ago. Nevertheless, the defining challenges for the 21st century will lie in the discovery in science, and deployment through engineering, of technologies that can deliver the scale needed to have an impact on the sustainability agenda. Thus the big developments in nanotechnology may lie not in the pursuit of yet smaller transistors, but in the design of new structures that can revolutionise the performance of solar cells, batteries, fuel cells, light-weight structural materials, refrigeration, water purification, etc. The science presented in the papers of this special section also highlights the underlying interest in energy-dense materials, which

  10. Nuclear power and public opinion

    International Nuclear Information System (INIS)

    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

  11. Strong Cosmic Censorship

    2017-01-01

    The Hawking-Penrose theorems tell us that solutions of Einstein's equations are generally singular, in the sense of the incompleteness of causal geodesics (the paths of physical observers). These singularities might be marked by the blowup of curvature and therefore crushing tidal forces, or by the breakdown of physical determinism. Penrose has conjectured (in his `Strong Cosmic Censorship Conjecture`) that it is generically unbounded curvature that causes singularities, rather than causal breakdown. The verification that ``AVTD behavior'' (marked by the domination of time derivatives over space derivatives) is generically present in a family of solutions has proven to be a useful tool for studying model versions of Strong Cosmic Censorship in that family. I discuss some of the history of Strong Cosmic Censorship, and then discuss what is known about AVTD behavior and Strong Cosmic Censorship in families of solutions defined by varying degrees of isometry, and discuss recent results which we believe will extend this knowledge and provide new support for Strong Cosmic Censorship. I also comment on some of the recent work on ``Weak Null Singularities'', and how this relates to Strong Cosmic Censorship.

  15. Topological evolution of the internet public opinion

    Lian, Ying; Dong, Xuefan; Liu, Yijun

    2017-11-01

    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 space is `n-strong arc connected' (n-sac) if for any n points in the space there is an arc in the space visiting them in order. A space is omega-strong arc connected (omega-sac) if it is n-sac for all n. We study these properties in finite graphs, regular continua, and rational continua. There are no 4-sac graphs, but there are 3-sac graphs and graphs which are 2-sac but not 3-sac. For every n there is an n-sac regular continuum, but no regular continuum is omega-sac. There is an omega-sac ...

    This paper shows that the counterexamples proposed by Strong in 2008 in the Journal of Medical Ethics to Marquis's argument against abortion fail. Strong's basic idea is that there are cases--for example, terminally ill patients--where killing an adult human being is prima facie seriously morally......'s scenarios have some valuable future or admitted that killing them is not seriously morally wrong. Finally, if "valuable future" is interpreted as referring to objective standards, one ends up with implausible and unpalatable moral claims....

  19. Examining Characteristics of Opinion Leaders in Social Media: A Motivational Approach

    Directory of Open Access Journals (Sweden)

    2016-08-01

    Full Text Available Social networking sites offer various opportunities to express opinions on politics and public affairs and to disseminate information to a large circle of acquaintances. The present research aims to identify the characteristics of people who consider themselves as opinion leaders on these new channels, the features they use in order to influence others, and the psychological motives they pursue. A survey ( N  = 527 among Facebook users identified political interest and personality strength as significant predictors of perceived Facebook opinion leadership, while the influence of extraversion was not significant. Those who write private messages on political debates do this in order to raise awareness of specific topics, while opinion expression in public status updates is also strongly connected to self-presentational goals (impression motivation. Moreover, the motives of presenting oneself positively and convincing others are particularly important for people with high personality strength. The present findings extend previous knowledge by redefining the concept of opinion leadership in new media environments and describing motivational links between individuals’ predispositions and their activities to influence others’ opinions. On a practical level, the pronounced role of self-presentational motives is likely to have important implications for the dynamics of public debates in social media.

  6. Strong Electroweak Symmetry Breaking

    CERN Document Server

    Grinstein, Benjamin

    2011-01-01

    Models of spontaneous breaking of electroweak symmetry by a strong interaction do not have fine tuning/hierarchy problem. They are conceptually elegant and use the only mechanism of spontaneous breaking of a gauge symmetry that is known to occur in nature. The simplest model, minimal technicolor with extended technicolor interactions, is appealing because one can calculate by scaling up from QCD. But it is ruled out on many counts: inappropriately low quark and lepton masses (or excessive FCNC), bad electroweak data fits, light scalar and vector states, etc. However, nature may not choose the minimal model and then we are stuck: except possibly through lattice simulations, we are unable to compute and test the models. In the LHC era it therefore makes sense to abandon specific models (of strong EW breaking) and concentrate on generic features that may indicate discovery. The Technicolor Straw Man is not a model but a parametrized search strategy inspired by a remarkable generic feature of walking technicolor,...

    Benjamín TEMKIN YEDWAB

    2013-06-01

    Full Text Available Although labor informality has been identified for years as a central issue for Latin American countries’ public policy, there is still scant information about the characteristics of informal employment in different spheres. The main objective of this study is to identify the views and political attitudes of informal workers in Latin America, and compare them to those held by their formal counterparts. Through a ‹‹proxy›› variable used to identify informal participants in the labor force in two opinion polls that apply to a broad set of countries in the region, it was possible to show that Latin American informals constitute a social group with political opinions and attitudes significantly contrasting with formal participants in the workforce.

  8. Which Characteristics of Gifted Students should be Developed? Student, Teacher and Parent Opinions

    M. Serdar Köksal

    2017-06-01

    Full Text Available The aim of this research was to investigate parent, student and teacher opinions about which characteristics of gifted students should be developed in cognitive, affective, psychomotor and social learning areas. The participants included 609 gifted students, 350 parents and 157 teachers from Science and Art Canters. Participants were surveyed using “The Which Characteristics of Gifted Students Should Be Developed”. The results of research revealed that students, parents and teachers agreed that social and affective skills should be improved. On the other hand, they held different opinions on the importance of music, art, dance, role-play, sport, domestic economy skills. This result indicates that these skills are thought by participants to be less important for gifted students’ development. In addition, teachers did not think technology so important for the development of gifted students, placing more emphasis on cognitive and affective domains.

    The author discusses the various ways to convince the greatest number of people to strongly reduce their greenhouse gas emissions. He first notes that the main reason for that is the perspective of fossil energy shortage, and comments some assessments of the cost of these energy savings, and ways to assess energy consumption with respect to carbon consumption savings. In order to promote better behaviours, he suggests that the State would define a normative value for fuel consumption by end users which would be independent of actual oil, coal or gas prices, and that any action would be considered as useful if it is less expensive that the use of oil, gas or any other fuel. He gives an overview of the already existing means to reduce emissions: biomass, nuclear energy, and energy savings. He proposes some ideas to convince consumers-users

  10. Issue-Relevant Values and Opinions About Gay Rights: Beyond Equality and Morality.

    Rhodebeck, Laurie

    2018-01-01

    Although many studies have examined the role of values in shaping public opinion, the number of values that inform this research is limited. This article employs the concept of issue-relevant values as a means to explore the broader range of values associated with policy issues. After discussing the concept in general terms, the article explores issue-relevant values pertinent to public opinion about gay rights. Using the policy examples of employment nondiscrimination and same-sex couple adoption, the present study identifies, measures, and assesses several values that add to the very short list previously used to explain public opinion about gay rights issues. Content from interest-group Web sites and news media coverage of the two issues aided in identifying the values. Data from an original Internet survey yield valid measures of the values. Multivariate analyses indicate that the values behave in predictable ways: they are strongly influenced by partisanship, and they strongly affect opinions about the two issues. The performance of the values is consistent with findings from previous research on the partisan basis of values and the value-based nature of opinions. The article concludes with suggestions for further empirical and theoretical work that could apply and extend the concept of issue-relevant values.

  11. Plasmons in strong superconductors

    International Nuclear Information System (INIS)

    Baldo, M.; Ducoin, C.

    2011-01-01

    We present a study of the possible plasmon excitations that can occur in systems where strong superconductivity is present. In these systems the plasmon energy is comparable to or smaller than the pairing gap. As a prototype of these systems we consider the proton component of Neutron Star matter just below the crust when electron screening is not taken into account. For the realistic case we consider in detail the different aspects of the elementary excitations when the proton, electron components are considered within the Random-Phase Approximation generalized to the superfluid case, while the influence of the neutron component is considered only at qualitative level. Electron screening plays a major role in modifying the proton spectrum and spectral function. At the same time the electron plasmon is strongly modified and damped by the indirect coupling with the superfluid proton component, even at moderately low values of the gap. The excitation spectrum shows the interplay of the different components and their relevance for each excitation modes. The results are relevant for neutrino physics and thermodynamical processes in neutron stars. If electron screening is neglected, the spectral properties of the proton component show some resemblance with the physical situation in high-T c superconductors, and we briefly discuss similarities and differences in this connection. In a general prospect, the results of the study emphasize the role of Coulomb interaction in strong superconductors.

  12. Information Filtering Based on Users' Negative Opinions

    Science.gov (United States)

    Guo, Qiang; Li, Yang; Liu, Jian-Guo

    2013-05-01

    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.

    2014-01-01

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

  14. EDITORIAL: Strongly correlated electron systems Strongly correlated electron systems

    2011-03-01

    Strongly correlated electrons is an exciting and diverse field in condensed matter physics. This special issue aims to capture some of that excitement and recent developments in the field. Given that this issue was inspired by the 2010 International Conference on Strongly Correlated Electron Systems (SCES 2010), we briefly give some history in order to place this issue in context. The 2010 International Conference on Strongly Correlated Electron Systems was held in Santa Fe, New Mexico, a reunion of sorts from the 1989 International Conference on the Physics of Highly Correlated Electron Systems that also convened in Santa Fe. SCES 2010—co-chaired by John Sarrao and Joe Thompson—followed the tradition of earlier conferences, in this century, hosted by Buzios (2008), Houston (2007), Vienna (2005), Karlsruhe (2004), Krakow (2002) and Ann Arbor (2001). Every three years since 1997, SCES has joined the International Conference on Magnetism (ICM), held in Recife (2000), Rome (2003), Kyoto (2006) and Karlsruhe (2009). Like its predecessors, SCES 2010 topics included strongly correlated f- and d-electron systems, heavy-fermion behaviors, quantum-phase transitions, non-Fermi liquid phenomena, unconventional superconductivity, and emergent states that arise from electronic correlations. Recent developments from studies of quantum magnetism and cold atoms complemented the traditional subjects and were included in SCES 2010. 2010 celebrated the 400th anniversary of Santa Fe as well as the birth of astronomy. So what's the connection to SCES? The Dutch invention of the first practical telescope and its use by Galileo in 1610 and subsequent years overturned dogma that the sun revolved about the earth. This revolutionary, and at the time heretical, conclusion required innovative combinations of new instrumentation, observation and mathematics. These same combinations are just as important 400 years later and are the foundation of scientific discoveries that were discussed

  15. Opinion formation with time-varying bounded confidence.

    When individuals in social groups communicate with one another and are under the influence of neighbors' opinions, they typically revise their own opinions to adapt to such peer opinions. The individual threshold of bounded confidence will thus be affected by both a change in individual confidence and by neighbor influence. Individuals thus update their own opinions with new bounded confidence, while their updated opinions also influence their neighbors' opinions. Based on this reasoned factual assumption, we propose an opinion dynamics model with time-varying bounded confidence. A directed network is formed by the rule of the individual bounded confidence threshold. The threshold of individual bounded confidence involves both confidence variation and the in/out degree of the individual node. When the confidence variation is greater, an individual's confidence in persisting in his own opinion in interactions is weaker, and the individual is more likely to adopt neighbors' opinions. In networks, the in/out degree is determined by individual neighbors. Our main research involves the process of opinion evolution and the basic laws of opinion cluster formation. Group opinions converge exponentially to consensus with stable neighbors. An individual opinion evolution is determined by the average neighbor opinion effect strength. We also explore the conditions involved in forming a stable neighbor relationship and the influence of the confidence variation in the convergence of the threshold of bounded confidence. The results show that the influence on opinion evolution is greater with increased confidence variation.

    Standard path-integral techniques such as instanton calculations give good answers for weak-coupling problems, but become unreliable for strong-coupling. Here we consider a method of replacing the original potential by a suitably chosen harmonic oscillator potential. Physically this is motivated by the fact that potential barriers below the level of the ground-state energy of a quantum-mechanical system have little effect. Numerically, results are good, both for quantum-mechanical problems and for massive phi 4 field theory in 1 + 1 dimensions. 9 references, 6 figures

    With an assumed weak multiplet structure for bosonic hadrons, which is consistent with the ΔI = 1/2 rule, it is shown that the strong interaction effective hamiltonian is compatible with the weak SU(2) x U(1) gauge transformation. Especially the rho-meson transforms as a triplet under SU(2)sub(w), and this is the origin of the rho-photon analogy. It is also shown that the existence of the non-vanishing Cabibbo angle is a necessary condition for the absence of the exotic hadrons. (orig.)

    In many political elections, the electorate appears to be a composite of partisan and independent voters. Given that partisans are not likely to convert to a different party, an important goal for a political party could be to mobilize independent voters toward the party with the help of strong leadership, mass media, partisans, and the effects of peer-to-peer influence. Based on the exact solution of classical voter model dynamics in the presence of perfectly partisan voters (i.e., zealots), we propose a computational method that uses pinning control strategy to maximize the share of a party in a social network of independent voters. The party, corresponding to the controller or zealots, optimizes the nodes to be controlled given the information about the connectivity of independent voters and the set of nodes that the opposing party controls. We show that controlling hubs is generally a good strategy, but the optimized strategy is even better. The superiority of the optimized strategy is particularly eminent when the independent voters are connected as directed (rather than undirected) networks.

    Taking the SNR-300 reactor in Kalkar as an example, the process of forming of political opinion and decision is reconstructed in order to get a picture of typical consensus- and conflict patterns in the discussion of safety problems. On this basis, it should be possible to derive a freedom of action for the political and administrative managing of safety matters by means of feed back with social groups. As a crucial point the aspects concerning the steps of the forming of political opinion and decision are examined. (DG) [de

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.

  1. Strong Coupling Holography

    CERN Document Server

    Dvali, Gia

    2009-01-01

    We show that whenever a 4-dimensional theory with N particle species emerges as a consistent low energy description of a 3-brane embedded in an asymptotically-flat (4+d)-dimensional space, the holographic scale of high-dimensional gravity sets the strong coupling scale of the 4D theory. This connection persists in the limit in which gravity can be consistently decoupled. We demonstrate this effect for orbifold planes, as well as for the solitonic branes and string theoretic D-branes. In all cases the emergence of a 4D strong coupling scale from bulk holography is a persistent phenomenon. The effect turns out to be insensitive even to such extreme deformations of the brane action that seemingly shield 4D theory from the bulk gravity effects. A well understood example of such deformation is given by large 4D Einstein term in the 3-brane action, which is known to suppress the strength of 5D gravity at short distances and change the 5D Newton's law into the four-dimensional one. Nevertheless, we observe that the ...

  3. Political opinion formation: Initial opinion distribution and individual heterogeneity of tolerance

    Science.gov (United States)

    Jin, Cheng; Li, Yifu; Jin, Xiaogang

    2017-02-01

    Opinion dynamics on networks have received serious attention for its profound prospects in social behaviours and self-organized systems. However, political opinion formation, as one typical and significant case, remains lacking in discussion. Previous agent-based simulations propose various models that are based on different mechanisms like the coevolution between network topology and status transition. Nonetheless, even under the same network topology and with the same simple mechanism, forming opinions can still be uncertain. In this work, we propose two features, the initial distribution of opinions and the individual heterogeneity of tolerances on opinion changing, in political opinion formation. These two features are imbedded in the network construction phase of a classical model. By comparing multi simple-party systems, along with a detailed analysis on the two-party system, we capture the critical phenomenon of fragmentation, polarization and consensus both in the persistent stable stage and in-process. We further introduce the average ratio of nearest neighbours to characterize the stage of opinion formation. The results show that the initial distribution of opinions leads to different evolution results on similar random networks. In addition, the existence of stubborn nodes plays a special role: only nodes that are extremely stubborn can cause the change of final opinion distribution while in other cases they only delay the time to reach stability. If stubborn nodes are small in number, their effects are confined within a small range. This theoretical work goes deeper on an existing model, it is an early exploration on qualitative and quantitative simulation of party competition.

  6. Reassessing Occupational Licensing Of Tour Guides (Opinion Piece

    Directory of Open Access Journals (Sweden)

    Amir SHANI

    2017-06-01

    Full Text Available It is conventionally held that to protect tourists from incompetent and/or unscrupulous tour guides, governments should require guides to be licensed in order to legally practice their profession. Despite the implementation of such regulatory statutes in many countries, it is argued in this opinion paper that the severe drawbacks of licensing demands should be re-evaluated by both policy-makers and tourism scholars. The licensing of guides is not only an ineffective means of quality assurance, with negative consequences for many of those involved, but it also undermines the ethical foundations of a free society. Furthermore, licensing is an archaic practice for ensuring standardization among the members of a profession in a way that is no longer suitable for addressing the challenges of the tourism industry in the 21st century, in which a wide variety of specialized and innovative guided tours are offered to tourists. Although this commentary presents a firm stand against the compulsory licensing of tour guides, it should be seen as an invitation for open discussion among tourism researchers regarding the necessity of licensing tour guides in particular, and of government tourism regulation in general. Moreover, further research is needed to clarify key points on the issue of the professional licensing of tour guides.

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

    Full Text Available A pesar de que la informalidad laboral ha sido identificada desde hace años como un asunto central para la política pública de todos los países de América Latina, es aún muy escasa la información sobre las características del empleo informal en diferentes esferas. El objetivo central de este trabajo es identificar las opiniones y actitudes políticas de los trabajadores informales en América Latina y compararlas con las de sus contrapartes formales. A través de una variable ‹‹proxi›› para identificar a los participantes informales en la fuerza de trabajo, en dos encuestas de opinión que se aplican a un conjunto amplio de países en la región, fue posible comprobar que los informales latinoamericanos constituyen un grupo social con opiniones y actitudes políticas significativamente contrastantes con las de los participantes formales en la fuerza de trabajo.Although labor informality has been identified for years as a central issue for Latin American countries’ public policy, there is still scant information about the characteristics of informal employment in different spheres.

    1985-06-01

    Forty-three states permit corporal punishment in schools. This practice continues despite the universal opposition of professional organizations, including the American Academy of Pediatrics. This study determines parental attitudes concerning the use of physical punishment in schools. The surveyed sample is drawn from parents of military dependents who brought their children to this clinic for routine physical examinations. One hundred and twenty-nine of 132 questionnaires were returned for a 98% response rate. Fifty-one percent of the parents supported the use of corporal punishment in schools, 37% disagreed (77% of these strongly), 11% had no opinion, and 1% did not respond to the question. Analysis of the responses displayed a relationship between parental attitudes on the use of corporal punishment and opinion of the positive effects of physical punishment on children's behavior (p less than 0.0001). No relationship was found between position on corporal punishment and the respondent (mother, father, or both), the age of parents, the military rank of the sponsor (the individual whose military service makes the child eligible for military medical care, i.e., father, mother, guardian, etc.), the sex of the children, the marital status of the parents, or the schools attended by the children (public or private). Thirty-four percent of parents believed corporal punishment would improve behavior, and 20% of parents felt that physical punishment would improve their child's academic performance.

    Wickens, F

    Our friend and colleague John Strong was cruelly taken from us by a brain tumour on Monday 31st July, a few days before his 65th birthday John started his career working with a group from Westfield College, under the leadership of Ted Bellamy. He obtained his PhD and spent the early part of his career on experiments at Rutherford Appleton Laboratory (RAL), but after the early 1970s his research was focussed on experiments in CERN. Over the years he made a number of notable contributions to experiments in CERN: The Omega spectrometer adopted a system John had originally developed for experiments at RAL using vidicon cameras to record the sparks in the spark chambers; He contributed to the success of NA1 and NA7, where he became heavily involved in the electronic trigger systems; He was responsible for the second level trigger system for the ALEPH detector and spent five years leading a team that designed and built the system, which ran for twelve years with only minor interventions. Following ALEPH he tur...

  4. Stirring Strongly Coupled Plasma

    CERN Document Server

    Fadafan, Kazem Bitaghsir; Rajagopal, Krishna; Wiedemann, Urs Achim

    2009-01-01

    We determine the energy it takes to move a test quark along a circle of radius L with angular frequency w through the strongly coupled plasma of N=4 supersymmetric Yang-Mills (SYM) theory. We find that for most values of L and w the energy deposited by stirring the plasma in this way is governed either by the drag force acting on a test quark moving through the plasma in a straight line with speed v=Lw or by the energy radiated by a quark in circular motion in the absence of any plasma, whichever is larger. There is a continuous crossover from the drag-dominated regime to the radiation-dominated regime. In the crossover regime we find evidence for significant destructive interference between energy loss due to drag and that due to radiation as if in vacuum. The rotating quark thus serves as a model system in which the relative strength of, and interplay between, two different mechanisms of parton energy loss is accessible via a controlled classical gravity calculation. We close by speculating on the implicati...

  5. Strong-interaction nonuniversality

    International Nuclear Information System (INIS)

    Volkas, R.R.; Foot, R.; He, X.; Joshi, G.C.

    1989-01-01

    The universal QCD color theory is extended to an SU(3) 1 direct product SU(3) 2 direct product SU(3) 3 gauge theory, where quarks of the ith generation transform as triplets under SU(3)/sub i/ and singlets under the other two factors. The usual color group is then identified with the diagonal subgroup, which remains exact after symmetry breaking. The gauge bosons associated with the 16 broken generators then form two massive octets under ordinary color. The interactions between quarks and these heavy gluonlike particles are explicitly nonuniversal and thus an exploration of their physical implications allows us to shed light on the fundamental issue of strong-interaction universality. Nonuniversality and weak flavor mixing are shown to generate heavy-gluon-induced flavor-changing neutral currents. The phenomenology of these processes is studied, as they provide the major experimental constraint on the extended theory. Three symmetry-breaking scenarios are presented. The first has color breaking occurring at the weak scale, while the second and third divorce the two scales. The third model has the interesting feature of radiatively induced off-diagonal Kobayashi-Maskawa matrix elements

    Full Text Available This paper presents an exploratory study of a selection of user contributions to a news feedback forum on the Web provided by the British Broadcasting Corporation (BBC World Service to its Arab listeners. Contributions representing Iraqi public opinion on a variety of topics covering Iraq under occupation were categorized and analyzed to provide a glimpse of how access to the Web has allowed Iraqis to freely express their opinions, and of how Iraqi public opinion manifests itself throughout these contributions. The results provided insights into the feelings of Iraqis towards the invasion and occupation of their country, and they highlighted the role played by the Web as a vital communication vehicle for public opinion and political debates.

  7. Decision Accuracy and the Role of Spatial Interaction in Opinion Dynamics

    Science.gov (United States)

    Torney, Colin J.; Levin, Simon A.; Couzin, Iain D.

    2013-04-01

    The opinions and actions of individuals within interacting groups are frequently determined by both social and personal information. When sociality (or the pressure to conform) is strong and individual preferences are weak, groups will remain cohesive until a consensus decision is reached. When group decisions are subject to a bias, representing for example private information known by some members of the population or imperfect information known by all, then the accuracy achieved for a fixed level of bias will increase with population size. In this work we determine how the scaling between accuracy and group size can be related to the microscopic properties of the decision-making process. By simulating a spatial model of opinion dynamics we show that the relationship between the instantaneous fraction of leaders in the population ( L), system size ( N), and accuracy depends on the frequency of individual opinion switches and the level of population viscosity. When social mixing is slow, and individual opinion changes are frequent, accuracy is determined by the absolute number of informed individuals. As mixing rates increase, or the rate of opinion updates decrease, a transition occurs to a regime where accuracy is determined by the value of L√{ N}. We investigate the transition between different scaling regimes analytically by examining a well-mixed limit.

  8. The interplay of self-reflection, social interaction and random events in the dynamics of opinion flow in two-party democracies

    Lichtenegger, Klaus; Hadzibeganovic, Tarik

    2016-01-01

    We propose a continuous process opinion formation model to study the dynamics of a multi-level relationship between voters, political parties, and facts in two-party democratic elections. In our model, opinions can take any real value between two extremes and an unaligned, moderate opinion state without a preference. Starting with a random opinion configuration, individual voter opinions evolve and change over time due to self-reflection, inter-personal communication, external media influence, and noise. Parties are influenced by their own ideologies, facts, and voters’ opinions. Elections are held periodically and the party that is closer in opinion to the majority of voters forms the new government. The government policy is then expected to be in proximity to the voter opinions and the policies of the currently ruling political party. We analyze the tension of opinions as a measure of how dramatically opinions can disagree within a given sample of voters and the success of the government and parties as the degree of coincidence between the policies and facts. Our model generates realistic quasi-periodic alternations between incumbents and challengers that are typical for two-party systems. Moreover, our model shows that relative to other voters’ strategies, conscious voting can lead to more successful governments of not only fact-oriented but also pragmatic and balanced political parties, irrespective of the strategies of the competing opposition parties. In addition, our simulations uncover several interesting features including less victories for strictly ideological or fact-oriented parties unless they include some aspects of populism or pragmatism. In this sense, our model can also describe situations where election outcomes are not necessarily based on votes for the current programs of competing parties and their placement on relevant issues, but instead result from voters’ dissatisfaction with the previous government and the votes against it.

    Opinion leaders represent one way to disseminate new knowledge and influence the practice behaviors of physicians. This study explored the stability of opinion leaders over time, whether opinion leaders were polymorphic (i.e., influencing multiple practice areas) or monomorphic (i.e., influencing one practice area), and reach of opinion leaders in their local network. We surveyed surgeons and pathologists in Ontario to identify opinion leaders for colorectal cancer in 2003 and 2005 and to identify opinion leaders for breast cancer in 2005. We explored whether opinion leaders for colorectal cancer identified in 2003 were re-identified in 2005. We examined whether opinion leaders were considered polymorphic (nominated in 2005 as opinion leaders for both colorectal and breast cancer) or monomorphic (nominated in 2005 for only one condition). Social-network mapping was used to identify the number of local colleagues identifying opinion leaders. Response rates for surgeons were 41% (2003) and 40% (2005); response rates for pathologists were 42% (2003) and 37% (2005). Four (25%) of the surgical opinion leaders identified in 2003 for colorectal cancer were re-identified in 2005. No pathology opinion leaders for colorectal cancer were identified in both 2003 and 2005. Only 29% of surgical opinion leaders and 17% of pathology opinion leaders identified in the 2005 survey were considered influential for both colorectal cancer and breast cancer. Social-network mapping revealed that only a limited number of general surgeons (12%) or pathologists (7%) were connected to the social networks of identified opinion leaders. Opinion leaders identified in this study were not stable over a two-year time period and generally appear to be monomorphic, with clearly demarcated areas of expertise and limited spheres of influence. These findings may limit the practicability of routinely using opinion leaders to influence practice.

    Full Text Available The increased use of alternative treatment for menopausal symptoms is mainly due to women’s changing opinions of conventional hormone replacement therapy (HRT. The objective of this study was to assess the opinion of pre and post-menopausal South African women regarding the potential menopause-related health benefits of soy. The sample used for the study was a sub-dataset of 825 respondents, which included only pre- and post-menopausal women that had heard of soy before, selected from a representative sample of the adult South African metropolitan and rural populations. A structured questionnaire was used. Neither age nor racial groups differed practically significantly in opinion regarding any of the various statements. The study also shows that a practically significant lower proportion of women in the sub-population across both age and race groups had a positive opinion on the health benefits of soy as an alternative to HRT and reliever of menopausal symptoms than those who acknowledged its benefit for preventing cardiovascular disease and osteoporosis. Practically significantly more women who used soy than women who never used soy agreed that soy keeps bones strong. In addition, more women who were of opinion that soy has few or no health benefits disagreed that soy could be used as an alternative to HRT compared to women who held a positive opinion.

    2010-12-01

    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

    Purpose: Assessment of bone maturity is traditionally performed through visual comparison of hand and wrist radiograph with existing reference images in textbooks. Our goal was to develop a digital index based on idealized hand Xray images that can be incorporated in a hand held computer and used for visual assessment of bone age for patients. Material and methods: Due to the large variability in bone maturation in normals, we generated a set of "ideal" images obtained by computer combinations of images from our normal reference data sets. Software for hand-held PDA devices was developed for easy navigation through the set of images and visual selection of matching images. A formula based on our statistical analysis provides the standard deviation from normal based on the chronological age of the patient. The accuracy of the program was compared to traditional interpretation by two radiologists in a double blind reading of 200 normal Caucasian children (100 boys, 100 girls). Results: Strong correlations were present between chronological age and bone age (r > 0.9) with no statistical difference between the digital and traditional assessment methods. Determinations of carpal bone maturity in adolescents was slightly more accurate using the digital system. The users did praise the convenience and effectiveness of the digital Palm Index in clinical practice. Conclusion: An idealized digital Palm Bone Age Index provides a convenient and effective alternative to conventional atlases for the assessment of skeletal maturity.

    Yarber, William L; Milhausen, Robin R; Crosby, Richard A; Torabi, Mohammad R

    2005-09-01

    Public opinion is important in determining condom and condom education policies in public high schools. A random telephone survey of 517 Indiana residents was conducted from July through October 2003 to assess public opinion about education on correct condom use for HIV and STD prevention; condom availability in Indiana public high schools; and issues related to condom use, effectiveness and promotion. Data were analyzed using bivariate and linear regression techniques. A majority of respondents strongly or somewhat agreed that instruction on correct condom use for HIV and STD prevention should be provided in public high schools (77%), classroom instruction should include condoms (71%), only medically accurate information about condoms should being given (94%) and the federal government should promote condoms (70%). Fewer than half (48%) strongly or somewhat agreed that condoms should be made available to teenagers in public high schools without parental permission. Nearly all (92%) considered condoms at least somewhat effective in preventing HIV and other STDs. Non-Republican party affiliation, younger age and condom use within the previous five years were each significantly associated with having positive opinions on many of the condom-related statements. Public opinion appears to support the provision of correct condom use information in Indiana public schools. Schools should consider providing only medically accurate information about condoms and including condoms in instruction so students can see and touch them.

It make use of a particular camera called intra-oral camera, also called dental camera, in order to perform the photo shooting and real-time video of the inner part of the mouth. The pictures acquired by the Operator with such a device are sent to the Oral Medicine Expert (OME) by means of a current File Transfer Protocol (FTP) service and the real-time video is channeled into a video streaming thanks to the VideoLan client/server (VLC) application. It is composed by a HTML5 web-pages generated by PHP and allows to perform the Second Opinion both when Operator and OME are logged and when one of them is offline.

  1. ETI, SETI and today's public opinion

    Science.gov (United States)

    Pinotti, Roberto

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

    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 argumentation-based negotiation the rhetorical illocutionary particles Appeals, Rewards and Threats have implications for the players that extend beyond a single negotiation and are concerned with building (business) relationships. This paper extends an agent's relationship-building argumentative repertoire with Opinions and Advice. A framework is described that enables agents to model their relationships and to use argumentative dialogue strategically both to achieve good negotiation outcomes and to build and sustain valuable relationships.

    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.

    2012-01-01

    Opinion dynamics focuses on the opinion evolution in a social community. Recently, some models of continuous opinion dynamics under bounded confidence were proposed by Deffuant and Krause, et al. In the literature, agents were generally assumed to have a homogeneous confidence level. This paper proposes an extended model for a group of agents with heterogeneous confidence levels. First, a social differentiation theory is introduced and a social group is divided into opinion subgroups with distinct confidence levels. Second, a multi-level heterogeneous opinion formation model is formulated under the framework of bounded confidence. Finally, computer simulations are conducted to study the collective opinion evolution, focusing on three key factors: the fractions of heterogeneous agents, the initial opinions, and the group size. The simulation results demonstrate that the number of final opinions depends on the fraction of close-minded agents when the group size and the initial opinions are fixed; the final opinions converge more easily when the initial opinions are closer; and the number of final opinions can be approximately modeled by a linear increasing function of the group size and the increasing rate is the fraction of close-minded agents.

    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.

    2011-08-01

    Key medical opinion leaders influence the behaviors of physicians and patients. By law, they have to disclose their interests with pharmaceutical companies when they communicate in the media. Up to now, it appears that no study has explored the effect of opinion leaders' disclosures despite their potential impact on public health and economy. The study objective was to assess the effects of opinion leaders' disclosures of interest on the public and general practitioners' trust in opinion leader by comparison with the overall medical community. In an experimental setting, three opinion leader profiles were built that differed only by the disclosure of their interests (hidden vs. weak vs. strong interests). One of the three profiles was randomly assigned to the subjects of two groups: 67 students and 60 general practitioners. According to an Anova analysis, the main effects and interactions of the disclosure of interests, of the message recipients, and of the assessed targets on the level of trust were measured. The results show that the average level of trust expressed by general practitioners was lower than that expressed by the general public. The level of trust in the opinion leader was lower than that of the overall medical community. The level of trust of exposed subjects fell much lower with stronger disclosed interests. While the general public did not distinguish trust between opinion leaders and the overall medical community, practitioners showed a significantly lower level of trust in opinion leaders with increasingly strong levels of disclosed interests. These study results refute the assertion that public trust would be reduced by the disclosure of interests. They reinforce the importance of the "who judges who" and "which kind of disclosure impacts who ?" effects and draw attention to further research on the role of social interactions in both mass and group communications.

    For a week last July, the University of Leicester played host to the 31st International Physics Olympiad. Sixty-three countries sent teams of five students, accompanied by two Leaders who were professors or teachers. The students faced two five-hour exams, one theory and one practical, woven into a week of visits and fun. The International Physics Olympiad has been held since 1967. The idea originated at a conference of the Czechoslovak Physical Society in Prague and the first competition was in Warsaw with teams from Bulgaria, Czechoslovakia, Hungary, Poland and Romania participating. The competition has grown in size and scope over the decades, and in 1991 it was awarded the medal of the International Commission on Physics Education. The citation reads `the International Physics Olympiad has become an achievement of world wide impact, and physics educators from various countries around the world have attested to the strong influence it has had in stimulating interests in physics among both students and teachers in their countries'. The British Physics Olympiad team was chosen from Year 13 students who had come through the selection procedure. Schools are invited to challenge their best pupils with a preliminary paper, sat and marked at school. Students gaining above a given threshold are encouraged to sit a second, three-hour paper, which is centrally marked and graded. From among the Gold-medal winners in this exam, the team of five is selected. Amid the pressures of A-levels, some practical and theory tuition is fitted in before the competition. The different countries use a variety of selection methods and coaching. The Australians managed a week of scientific and cultural education in Vienna prior to arriving at Leicester, and several teams talked of pre-competition work-camps. How much Physics can be crammed into a week? Countries that have institutions selecting pupils highly gifted in Maths and Science have a great start, as do those with the most

    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.

  3. To drill or not to drill? An econometric analysis of US public opinion

    Mukherjee, Deep; Rahman, Mohammad Arshad

    2016-01-01

    Offshore drilling in the United States (US) has been the subject of public and political discourse due to multiple reasons which include economic impact, energy security, and environmental hazard. Consequently, several polls have been conducted over time to gauge public attitude towards offshore drilling. Nevertheless, the economic literature on this issue is sparse. This paper contributes to the literature and analyzes support for offshore drilling based on demographic, economic, social, belief, and shock (e.g. spill) factors. The data is taken from ten nationwide surveys conducted before, during and after the British Petroleum (BP) oil spill and analyzed within the framework of discrete choice model. The results from an ordinal probit model demonstrate that age, annual household income, affiliation to Republican Party, and residence in oil-rich states positively affect the probability of strong support and reduce the probability of strong opposition for offshore drilling. In contrast, the female gender, higher education, association to Democratic Party, and environmental concern affect opinion in opposite direction. Marginal effects show that belief about environmental consequences of drilling has the highest impact on opinion. Binary probit model also yields a similar result and suggests that BP oil disaster resulted in a transient decrease in support for offshore drilling. - Highlights: •US public opinion on offshore drilling is analyzed based on ten national polls. •Ordinal and binary probit models are utilized to identify the underlying factors that shape public opinion. •Belief about environmental cost of drilling and educational attainment have the highest negative impact on opinion. •Age, income, affiliation to Republican party and oil-rich states positively affect support for drilling. •BP oil spill resulted in a transient decrease in support for offshore drilling.

Cosponsors included the International Association of Hydrogeologists (IAH), the International Society for Soil Mechanics and Foundation Engineering (ISSMFE), and the Association of Geoscientists for International Development (AGID).Organized within the framework of UNESCO's International Hydrological Program, the symposium brought together over 200 international interdisciplinary specialists in the problems of land subsidence due to fluid and mineral withdrawal. Because man's continuing heavy development of groundwater, gas, oil, and minerals is changing the natural regime and thus causing more and more subsiding areas in the world, there had been sufficient new land subsidence occurrence, problems, research, and remedial measures since the 1976 Second International Symposium held in Anaheim, California, to develop a most interesting program of nearly 100 papers from about 30 countries. The program consisted of papers covering case histories of fluid and mineral withdrawal, engineering theory and analysis, karst “sink-hole”-type subsidence, subsidence due to dewatering of organic deposits or due to application of water (hydrocompaction), instrumentation, legal, socioeconomic, and environmental effects of land subsidence, and remedial works.

  9. Trends in Public Opinion on Nuclear Energy in Slovenia

    International Nuclear Information System (INIS)

    Jencic, I.

    2008-01-01

    Slovenia is considering building a second nuclear power plant in the next 10-15 years, 'if no other, better option to generate electricity becomes feasible in this period.' It is quite obvious that this cautious wording is used in the official government plan because of sensitivity of public towards nuclear energy and potential political feedback. The Nuclear Training Centre was established in 1989 as an organizational unit of Jozef Stefan Institute. Its main mission was - and still is - the initial, theoretical training of NPP operators. Over the years, this mission was complemented by an increasingly intensive activity in public information. The core of this activity is the Information centre which was set up in the basement of the Training Centre in 1993 and which received the 100.000th visitor in May 2007. Public information of the Nuclear Training Centre is based of live lectures, visit of the permanent exhibition, demonstration laboratory, printed materials and web page. A selected group of visitors is also polled each year on the topic of nuclear energy. The poll is performed before the visit in order to receive unbiased opinion. We are aware that the results of these polls are not representative for general public in Slovenia, but to some extent they do reflect public opinion and, even more important, they can be used to monitor changes over the years and also to serve as a guide to information activities. This year we have also started to follow the reports on nuclear energy in the media: what are the topics that media report most, how do they report and in which types of media these reports appear. The paper will describe the results of public opinion polls in the last year and their comparison with the results of polls in the previous years, as well as their comparison with a recent Eurobarometer poll on nuclear safety. Furthermore, analysis of media coverage will be presented. All these data are considered in estimating the strong and the weak points of

  13. The noisy Hegselmann-Krause model for opinion dynamics

    Science.gov (United States)

    Pineda, Miguel; Toral, Raúl; Hernández-García, Emilio

    2013-12-01

    In the model for continuous opinion dynamics introduced by Hegselmann and Krause, each individual moves to the average opinion of all individuals within an area of confidence. In this work we study the effects of noise in this system. With certain probability, individuals are given the opportunity to change spontaneously their opinion to another one selected randomly inside the opinion space with different rules. If the random jump does not occur, individuals interact through the Hegselmann-Krause's rule. We analyze two cases, one where individuals can carry out opinion random jumps inside the whole opinion space, and other where they are allowed to perform jumps just inside a small interval centered around the current opinion. We found that these opinion random jumps change the model behavior inducing interesting phenomena. Using pattern formation techniques, we obtain approximate analytical results for critical conditions of opinion cluster formation. Finally, we compare the results of this work with the noisy version of the Deffuant et al. model [G. Deffuant, D. Neu, F. Amblard, G. Weisbuch, Adv. Compl. Syst. 3, 87 (2000)] for continuous-opinion dynamics.

    Science.gov (United States)

    Xiong, Fei; Liu, Yun; Wang, Liang; Wang, Ximeng

    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.

    To reflect the opinions of inhabitants of the district to the business management of JNC (Japan Nuclear Cycle Development Institute), it charged local residents with monitor of J NC monitor Ibaraki . Their tenures of office are one year. The meetings are held for three periods from fiscal 1999 to fiscal 2001. Abstract of monitor's opinions and consciousness change are reported. On JNC, 1) many monitors wish to give safety the highest priority. 2) Many monitors demand easy explanation without the technical terms. 3) Many monitors think that the JNC staffs do not react to the accident for their parts and not to open information. 4) Many monitors wish to continue the monitor system, because it is good system for an interchange of opinions between local resident and the staff. On consciousness change of monitor, the impression on JNC was changed by experience of monitor. Almost monitor think nuclear power is needed, but about 80% of them felt unrest after experience of monitor. It consists of ten chapters as followings; introduction, JNC monitors Ibaraki, abstract of meetings, main opinions from monitors, an attitude survey on JNC accident and before and after of experience of monitor, results of the questionnaire, discussion of each question, determination of JCO, conclusions and data.

    Optical spectroscopy is without doubt one of the most important non-contact measurement principles. It is used in a wide range of applications from bio-medical to industrial fields. One recent trend is to miniaturize spectral sensors to address new areas of application. The most common spectral sensor type is based on diffraction gratings, while other types are based on micro mechanical systems (MEMS) or filter technologies. The authors represent the opinion that there is a potentially wide spread field of applications for spectrometers, but the market limits the range of applications since they cannot keep up with targeted cost requirements for consumer products. The present article explains an alternative approach for miniature multichannel spectrometer to enhance robustness for hand held field applications at a cost efficient price point.

    To 2000 people who were randomly sampled from the basic register of residents in Fukui prefecture, we conducted a questionnaire survey asking their interest in, knowledge of and attitude toward nuclear power, to analyze which perceptions and opinions they had and factors influencing them. The ratios of respondents in Fukui prefecture who think nuclear power is safe, necessary, and should be developed more, are higher than those of surveyed residents who live in other regions where nuclear power plants had been in operation. Differences in gender and age are nearly the same as those found in the nation-wide surveys has shown. The respondents in 'Tsuruga' region, one of the centers of nuclear power research and development, are more acceptive and affirmative to the nuclear power than those in other regions, although they have less knowledge and credibility for nuclear power safety measures, such as regulation and monitoring by government, countermeasure of earthquake, training of workers and so on. We analyzed the perception of risk and the sense of security for nuclear power, and the opinions for necessity and development of nuclear power, using a regression model. According to the estimated 'Tsuruga' model, risk perception of Tsuruga respondents does not affect their opinion if nuclear power should be developed. No influence of the risk perception on their opinion for nuclear power suggest a possibility that residents have strong trust in nuclear power technology and electric power companies based on their long term experience.

    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.

  19. Quantitative Agent Based Model of Opinion Dynamics: Polish Elections of 2015

    2016-01-01

    We present results of an abstract, agent based model of opinion dynamics simulations based on the emotion/information/opinion (E/I/O) approach, applied to a strongly polarized society, corresponding to the Polish political scene between 2005 and 2015. Under certain conditions the model leads to metastable coexistence of two subcommunities of comparable size (supporting the corresponding opinions)—which corresponds to the bipartisan split found in Poland. Spurred by the recent breakdown of this political duopoly, which occurred in 2015, we present a model extension that describes both the long term coexistence of the two opposing opinions and a rapid, transitory change due to the appearance of a third party alternative. We provide quantitative comparison of the model with the results of polls and elections in Poland, testing the assumptions related to the modeled processes and the parameters used in the simulations. It is shown, that when the propaganda messages of the two incumbent parties differ in emotional tone, the political status quo may be unstable. The asymmetry of the emotions within the support bases of the two parties allows one of them to be ‘invaded’ by a newcomer third party very quickly, while the second remains immune to such invasion.

    Intermittent exotropia (IXT) can be a controversial topic, often eliciting lively discussion. This lecture will discuss its definition, incidence, age of onset, presentation, natural variation, criteria for deterioration, goals of treatment, effectiveness of surgical treatment, types of surgical treatment, and unwanted effects of surgical treatment. Results from the scientific literature, opinions of respected colleagues, the opinion of the author, and the results of live polling of the audience during the John Pratt-Johnson lecture are presented. IXT is defined as an exotropia that is present intermittently predominantly for distance. Its incidence is about 1% and it usually has an onset before age 5. Patients often present because of concern regarding the appearance of the eye misalignment. There is natural variation in the control of IXT, the angle of IXT, and the amount of stereopsis. Criteria that denote deterioration are increasing frequency of IXT, progressively and consistently increasing angle of IXT, loss of binocular vision, and increasing concern regarding the patient's appearance and its effect on social interaction. Goals of treatment are to retain equal or nearly equal vision, to obtain acceptable cosmesis, and to retain binocular vision. The long-term success of surgical treatment is not well proven. Persistent postoperative overcorrection is an unwanted effect of surgical treatment. The inherent biologic variation that occurs when measuring the components of IXT makes it difficult to be dogmatic about IXT, particularly when trying to decide when deterioration is occurring.

    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.

    Full Text Available Writers can apply interpersonal metadiscourse markers to encode an interaction and build a relationship with their readers. In some particular genres, such as newspaper discourse, they can even be used as means of attaining persuasive goals. Initiated by the idea, the present writer attempts to explore the use of interpersonal metadiscourse markers in Indonesian newspaper opinion articles. This present study aims to investigate interpersonal metadiscourse categories and subcategories applied and most predominantly occuring in the type of newspaper article. For the data, eleven selected articles of an Indonesian newspaper were taken to analyze by using Dafouz’s (2008 classification of interpersonal metadiscourse markers. Results reveal that interpersonal metadiscourse categories (hedges, certainty markers, attributors, attitude markers, and commentaries and subcategories (epistemic verbs, probability adverbs, deontic verbs, attitudinal adverbs, attitudinal adjectives, cognitive verbs, rhetorical questions, inclusive expressions, personalizations, and asides were used in Indonesian opinion articles. It is also found that attitude markers and two subcategories, which are deontic and epistemic verbs, are most frequently present in the texts.

    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.

    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.

    Full Text Available The study of the going concern audit opinions is an important component within the enhancement of firms’ responsibility and stewardship. A going concern audit opinions implies that the independent auditor doubt the future of the firm. This study aimed to examine the drivers of the likelihood of the going-concern audit opinions. Previous studies revealed that there were inconsistent drivers influencing the going-concern audit opinion. This study shows similar results to prior works. The result indicates that firms’ financial condition and profitability significantly affect the likelihood of the going-concern audit opinion, while firms’ size and leverage are not the determinants of the intensity of the going concern audit opinion.

    We report the findings and outputs of an international expert opinion process to develop a definition of early Crohn's disease (CD) that could be used in future disease-modification trials. Nineteen experts on inflammatory bowel diseases held an international expert opinion meeting to discuss and agree on a definition for early CD to be used in disease-modification trials. The process included literature searches for the relevant basic-science and clinical evidence. A published preliminary definition of early CD was used as the basis for development of a proposed definition that was discussed at the expert opinion meeting. The participants then derived a final definition, based on best current knowledge, that it is hoped will be of practical use in disease-modification trials in CD.

    Human amyloid imaging is one of the great recent translational medicine stories. Beginning with the recognition that Thioflavin T derivatives could be used as PET tracers, through development of Pittsburgh compound B, to Food and Drug Administration (FDA) approval of Florbetapir in 2012, human amyloid imaging has held great promise to allow in vivo inclusive diagnosis of Alzheimer disease (AD), even though the first principle of amyloid PET is that it functions as a surrogate for β-amyloid pathology, and not necessarily as a surrogate for the diagnosis of AD.(1,2.)

  12. IN MY OPINION: Is Physics debatable?

    Science.gov (United States)

    Dobson, Ken

    2000-01-01

    Stephen Jay Gould is, unfortunately, a palaeontologist. I write unfortunately because if he were a physicist we would all have benefited from his innumerable entertaining and informative essays [1]. His steady theme involves an obscure subject like palaeontology and why the subject links so strongly with the human condition. The key, of course, is evolution, and the light it sheds on what it means to be human. The new National Curriculum for England (and probably Wales) requires that pupils be taught: * how scientific controversies can arise from different ways of interpreting empirical evidence and models based on this evidence, and * ways in which scientific ideas may be affected by the context in which they develop, e.g. social, historical, moral and spiritual , and how these contexts may affect whether or not the ideas are accepted. Stephen Jay Gould produces an essay a month (in the US Natural History magazine) and so seems to have few problems in finding topics to write about that would fit well into one or both of the National Curriculum requirements. Good for biologists, but it doesn't seem to be so easy in physics. Admittedly Gould has to have recourse to a great number of historical cases - but he usually manages to link these with up-to-date issues. After all, he comes from a country where several states put `creation science' on a par with the Darwinian model of Earth history, so he has not only scope but need for encouraging some humane rationality. Can the history of physics provide such relevance? Does physics provide nice meaty controversies that might tempt the adolescent to think? We might be able to tell some stories with some level of drama, but it is hard for teachers to produce much enthusiasm in ordinary students at age 14 to 16 for controversies between Newton and Hooke, or Newton and Leibnitz (or Newton and most of his contemporaries, to be honest). They might be made to sympathize with Thomas Young, agonize over Boltzmann, celebrate with

    2013-12-01

    We consider a PageRank model of opinion formation on Ulam networks, generated by the intermittency map and the typical Chirikov map. The Ulam networks generated by these maps have certain similarities with such scale-free networks as the World Wide Web (WWW), showing an algebraic decay of the PageRank probability. We find that the opinion formation process on Ulam networks has certain similarities but also distinct features comparing to the WWW. We attribute these distinctions to internal differences in network structure of the Ulam and WWW networks. We also analyze the process of opinion formation in the frame of generalized Sznajd model which protects opinion of small communities.

  15. 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 fast epidemic process drives individual opinions to converge more obviously. Unlike previous epidemic models, the number of infected agents does not always increase with the update rate, but has a peak with an intermediate value of the rate. (paper)

    The study was part of a series of studies aiming to increase knowledge about spread and prevention of livestock diseases in Sweden. A specific biosecurity behavior, i.e., making professionals (e.g., veterinarian, repairman, livestock transporter) wear clean protective clothing when entering the stables was investigated through focus groups and a questionnaire survey. This behavior was seen as a proxy for other biosecurity behaviors. As part of questionnaire development, three focus group discussions with a total of 11 participating livestock farmers were held. The questionnaire was based on the model of Theory of Planned Behavior. Response was received from 2,081 farmers. In the focus groups, farmers expressed a willingness to provide visitors with clean protective clothing. However, some had experienced difficulties in making veterinarians use protective clothing, and mentioned a reluctance to correct their veterinarians. The participants mostly focused on diseases regulated by control programs, especially Salmonella. In parts, participants were well informed but some showed a lack of knowledge concerning routes of disease spread. They also mentioned external factors that made them deviate from biosecurity recommendations. Farmers called for biosecurity advice with focus on cost–benefit return. Among survey respondents, the intention to make visitors wear protective clothing was moderate. Analysis of underlying elements showed that a majority of farmers (88%) had a neutral attitude, i.e., they were neither in favor nor against this behavior. Measures of subjective norm indicated a varying degree of social pressure among respondents. However, the majority (63%) indicated a strong behavioral control, thus suggesting that they could make visitors use protective clothing if they wanted to. Although most farmers (84%) indicated a strong willingness to comply with the opinion of their veterinarians in biosecurity matters, 30% replied that their farm veterinarian is

    Full Text Available The new, alternative thinking patterns in marketing highlight the fact that exchanges per se are not the focus of marketing analysis and researches; rather than that, they must surrender this position to relationships between different sides in the marketing setting - the company and consumers, internal relations within companies, and relations between consumers themselves. A new philosophy, relationship marketing, is taking over the position of the old transaction marketing philosophy. The greatest challenge for marketing professionals at the beginning of the 21st century is this third dimension of relationships - relations between consumers, their mutual impact on preferences and purchase decisions, and, most notably, the possibility of involving consumers in companies marketing mix programs. Opinion leaders - their identification, creation, their word-of-mouth communication, its emergence and impact are currently the focus of marketing theory and practice.

Most participants related smoking initiation to the smoking behavior of peers and family members, but easy accessibility to cigarettes, ineffective rules and regulations, and exposure to passive smoking...

  2. Democracy, public opinion, and nuclear weapons

    International Nuclear Information System (INIS)

    Russett, B.

    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

    We examined public opinion of sexual expression and dementia to inform nursing home policy and practice. A content analysis was conducted on public comments (N=1194) posted in response to a New York Times article about a highly publicized legal case involving a husband engaging in sexual acts with his wife who had dementia, living in a nursing home. Researchers utilized constant comparative analysis to code the comments; reliability analysis showed moderately strong agreement at the subcategory level. Data were also coded to indicate whether the commenter thought the couple should or should not have been allowed to be sexual. One primary theme was identified: conditions necessary for someone to be sexual. Six categories were identified within this theme, with the public commentary considering factors such as marital relationships, intimacy needs and several sexual consent-related issues as key conditions necessary to be sexual in a nursing home setting. Overall, the majority of commenters were in support of sexual expression for an individual with dementia in the described situation. This study revealed sexual expression among individuals with dementia is a contentious issue with strong public opinions about how this should be managed in a nursing home setting. These opinions should be considered as policy related to sexual expression in nursing homes is developed. © 2016 The Authors. Health Expectations Published by John Wiley & Sons Ltd.

  6. Strong WW Interaction at LHC

    We present a brief pedagogical introduction to the Effective Electroweak Chiral Lagrangians, which provide a model independent description of the WW interactions in the strong regime. When it is complemented with some unitarization or a dispersive approach, this formalism allows the study of the general strong scenario expected at the LHC, including resonances.

    A first and synthetic part of this report comments the most remarkable results of the opinion survey. It first addresses results related to a context of economic crisis (importance of the economic crisis and unemployment as major concerns for French people, environmental concerns) and then analyzes the different aspects of the nuclear risk, from the accident to nuclear safety: strong fears of a nuclear accident, Fukushima and Chernobyl are immediately present in people's mind, concerns about nuclear are also related to the environment and health, the actual benefit of nuclear is an economic one, nuclear safety is a major challenge on which French people doubt, French people wish a citizen look on nuclear safety, the opinion of French people on nuclear worsened in 2013. Then, this report, illustrated by several graphs, presents and discusses the results of an annual opinion survey on the present concerns of French people (in the present society, for the environment, and as far as science is concerned), the opinion of French people on expertise (about who must control a risky installation, about the role and image of scientific experts, about the diffusion and sharing of scientific expertise, and about the perception of pluralistic structures), on the attitude of French people in front of 33 risk situations (risks to which French people feel exposed to, confidence of French people in authorities to protect them, the truth of information on hazards, the hierarchy of 33 situations according to 3 aspects and their relationship with installation acceptability). The fourth part addresses more particularly the nuclear sector: expectations in terms of nuclear risk management, fear of a serious accident, benefits and drawbacks of nuclear energy, skill and credibility of interveners. Graphs notably present the evolution of opinions with respect to last year or over the past years

    Full Text Available Background: Auditing can support national democratic processes, national development and government good will. Supreme Audit Institutions (SAI, such as offices of Auditor General, publish consolidated reports on audit outcomes for local authorities, government departments, parastatals and related public entities. These reports identify broad areas analysed during audit exercises that often include financial management, governance, asset management, risk management, revenue collection and debt recovery. They highlight trends that were detected during audit exercises at the end of a financial year. The reports further show how records and records management affect audit exercises as well as financial management within the audited institutions. Objectives: The intention of the research was to ascertain the contribution of records management to audit opinions and accountability in financial management in Zimbabwean government entities. Method: A document analysis of Comptroller and Auditor General of Zimbabwe (CAGZ’s reports was used to identify the types of decisions and recommendations (audit opinions issued, in juxtaposition to the records management issues raised. Results and Conclusion: This study shows that there is a strong correlation between records management concerns and audit opinions raised by the CAGZ’s narrative audit reports. Inadequate records management within government entities was associated with adverse and qualified opinions and, in some cases, unqualified opinions that had emphases of matter. There was a causal loop in which lack of documentary evidence of financial activities was the source cause of poor accounting and poor audit reports. Errors resulting from incomplete or inaccurate records meant that government entities were not showing a true picture of their financial status and their financial statements could be materially misstated. As an important monitoring and control system, records management should be

    The calculation decides the integrity of the safety latch that will hold the strong-back to the pump during lifting. The safety latch will be welded to the strong-back and will latch to a 1.5-in. dia cantilever rod welded to the pump baseplate. The static and dynamic analysis shows that the safety latch will hold the strong-back to the pump if the friction clamps fail and the pump become free from the strong-back. Thus, the safety latch will meet the requirements of the Lifting and Rigging Manual for under the hook lifting for static loading; it can withstand shock loads from the strong-back falling 0.25 inch

  11. Partisans without Constraint: Political Polarization and Trends in American Public Opinion.

    Baldassarri, Delia; Gelman, Andrew

    2008-01-28

    Public opinion polarization is here conceived as a process of alignment along multiple lines of potential disagreement and measured as growing constraint in individuals' preferences. Using NES data from 1972 to 2004, the authors model trends in issue partisanship-the correlation of issue attitudes with party identification-and issue alignment-the correlation between pairs of issues-and find a substantive increase in issue partisanship, but little evidence of issue alignment. The findings suggest that opinion changes correspond more to a resorting of party labels among voters than to greater constraint on issue attitudes: since parties are more polarized, they are now better at sorting individuals along ideological lines. Levels of constraint vary across population subgroups: strong partisans and wealthier and politically sophisticated voters have grown more coherent in their beliefs. The authors discuss the consequences of partisan realignment and group sorting on the political process and potential deviations from the classic pluralistic account of American politics.

    The purpose of this brief report is to describe the adoption of hand-held dynamometry, a procedure for documenting muscle strength. Between the early 1900s and the end of 2005, 478 research articles were published that documented use of hand-held dynamometry. The adoption of the procedure for research is consistent with the S-shaped curve described by Rogers. The extent to which hand-held dynamometry is used in clinical practice remains to be delineated.

  14. Conformity, Anticonformity and Polarization of Opinions: Insights from a Mathematical Model of Opinion Dynamics

    2017-07-01

    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.

    Titanium (Ti) is a strong silver-gray metal that is highly resistant to corrosion and is chemically inert. It is as strong as steel but 45 percent lighter, and it is twice as strong as aluminum but only 60 percent heavier. Titanium dioxide (TiO2) has a very high refractive index, which means that it has high light-scattering ability. As a result, TiO2 imparts whiteness, opacity, and brightness to many products. ...Because of the unique physical properties of titanium metal and the whiteness provided by TiO2, titanium is now used widely in modern industrial societies.

  16. MARKET CHOICES FOR BROILER CHICKEN MEAT IN THE OPINION

    Directory of Open Access Journals (Sweden)

    2014-09-01

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

    This study examined air medical transport (AMT) personnel's experiences with and opinions about prehospital and AMT research. A Web-based questionnaire was sent to eight randomly selected AMT programs from each of six Association of Air Medical Services (AAMS) regions. Responders were defined by university association (UA) and AMT professional role. Forty-eight of 54 (89%) contacted programs and 536 of 1,282 (42%) individuals responded. Non-UA responders (74%) had significantly more work experience in emergency medical services (EMS) (13.5 +/- 8.5 vs. 10.8 +/- 8.3 years, P = .002) and AMT (8.3 +/- 6.3 vs. 6.8 +/- 5.7 years, P = .008), whereas UA responders (26%) had more research training (51% vs. 37%, P = .006), experience (79% vs. 59%, P < .001), and grants (7% vs. 2%, P = .006). By AMT role, administrators had the most work experience, and physicians had the most research experience. Research productivity of responders was low, with only 9% having presented and 10% having published research; and UA made no difference in productivity. A majority of responders advocated research: EMS (66%) and AMT (68%), program (53%). Willingness to participate in research was high for both EMS research (87%) and AMT research (92%). Although AMT personnel were strong advocates of and willing to participate in research, few had research knowledge. For AMT personnel, disparity exists between advocating for and producing research.

  18. Automatic feeder for small fish held in tanks

    Joeris, Leonard S.

    1965-01-01

    The Northville (Michigan) Biological Station has been a center for study of the developmental morphology of coregonid fishes. This work requires the production of numerous individual series of lake herring, lake whitefish, and several species of chubs from parent fish of positively known identity. The offspring of individual pairs or groups of fish must be held in individual tanks from the time they hatch until they reach maturity. One of the important problems in this project has been the poor growth of most fish. Though some have grown well, their growth has been less than that of the same species in nature, and a few fish from each hatch have grown very slowly. Irregularity of feeding may contribute to the slow growth of laboratory fish. The hatchery caretaker feeds them several times during his 8-hour workday, but they must go without food during the remaining 16 hours. The high metabolic rate of small fish, however, appears to make them strongly inclined toward almost continual feeding. Belief that greater, more regular food consumption would result from a mechanical feeder providing a continuous supply of food over a longer period of the day led to development of the equipment described in this paper.

    Zhou, Xin; Chen, Bin; Liu, Liang; Ma, Liang; Qiu, Xiaogang

    2015-01-01

    In order to study the formation process of group opinion in real life, we put forward a new opinion interactive model based on Deffuant model and its improved models in this paper because current models of opinion dynamics lack considering individual persuasiveness. Our model has following advantages: firstly persuasiveness is added to individual's attributes reflecting the importance of persuasiveness, which means that all the individuals are different from others; secondly probability is introduced in the course of interaction which simulates the uncertainty of interaction. In Monte Carlo simulation experiments, sensitivity analysis including the influence of randomness, initial persuasiveness distribution, and number of individuals is studied at first; what comes next is that the range of common opinion based on the initial persuasiveness distribution can be predicted. Simulation experiment results show that when the initial values of agents are fixed, no matter how many times independently replicated experiments, the common opinion will converge at a certain point; however the number of iterations will not always be the same; the range of common opinion can be predicted when initial distribution of opinion and persuasiveness are given. As a result, this model can reflect and interpret some phenomena of opinion interaction in realistic society.

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

    Science.gov (United States)

    Gargiulo, Floriana; Ramasco, José J

    2012-01-01

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

  7. Nuclear power: Public opinion in social crisis

    International Nuclear Information System (INIS)

    Gagarinski, A.

    1995-01-01

    Nuclear power in Russia found itself in new conditions, if compared with first five years after Chernobyl. It is coming out of the technology crisis from 1986 and the political crisis of 1991, going deeper and deeper in the hard economic crisis, when the nuclear power plants receive about 10 percent of payments for electricity, produced and supplied to the customers. Economic crisis forms the public attitude about nuclear power under conditions, different from opinion formed during the previous decades, when energy supply was considered practically free of charge. These realities have moved ecological problems to the periphery of public conscience. This was, in particular, shown with all evidence during the parliamentary elections in Russia in 1993, when the Russian 'Green Party' had not achieved any seats in the State Duma. This is also confirmed by sociological polls of Russians done in the last two years. It seems, however, that change of priorities in public opinion had increased attention to the problems of environment in the nearest future are as inevitable, as the forthcoming Russia's and Its nearest neighbours getting out of the state of economic fail down. In these conditions the possibility of nuclear power development will be determined not only by economic factors, but also by the factor of public confidence. The progress in the development of public information programme in the field of nuclear power, if compared with the first years after Chernobyl, is evident. Several governing and coordinating structures exist and work in Russia (Department of Minatom, Inter-departmental Council for information and public relations, similar Department in Rosenergoatom Concern), regional public information centres, special services at many nuclear science and industry enterprises. Similar system works in Ukraine and is being established in Kazakhstan. In antinuclear Belarus, where, nevertheless, the objective need of nuclear power is already reflected in the national

    Understanding the emergence of extreme opinions and in what kind of environment they might become less extreme is a central theme in our modern globalized society. A model combining continuous opinions and observed discrete actions (CODA) capable of addressing the important issue of measuring how extreme opinions might be has been recently proposed. In this paper I show extreme opinions to arise in a ubiquitous manner in the CODA model for a multitude of social network structures. Depending on network details reducing extremism seems to be possible. However, a large number of agents with extreme opinions is always observed. A significant decrease in the number of extremists can be observed by allowing agents to change their positions in the network.

    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.

  10. Energy policy decision making and public opinion

    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

    As educators who teach courses that examine social power, we often struggle with a specific form of resistance in the equity-oriented classroom: "That's just [the author]'s opinion." This "opinion discourse" emerges when students study scholarship that unsettles dominant knowledge claims and methods or when students are themselves asked to situate…

    Full Text Available This study aims to examine public and private school teachers’ opinions on different aspects of their professional associations and provisions and also asks principals about teachers’ conduct and their views on the Nigerian curriculum. To conduct this study, qualitative and quantitative research models were used to investigate differences between the two organizations. Quantitative data was collected by distributing questionnaires to 118 teachers in the Abuja Municipal Area Council (AMAC, Nigeria. To conduct the qualitative analysis, 15 teachers from two schools were selected (a total of 30 teachers to answer 5 discussion questions concerning their views on the Nigerian educational system. The findings revealed that private school teachers are at an advantage when it comes to provision of resources and technology, professional development and to some degree salaries. Both public and private school teachers felt being a teacher did not bring them respect in their community. Government policy makers need to study private schools and how they operate to see how they can make changes to produce the revolutionary reform needed in education. 30 principals’ interviews revealed that public school teachers are not easily held accountable for misconduct due to the structure of leadership, while private school teachers are held accountable and any form of unprofessionalism easily leads to termination of employment.

    Since the beginning of the year French media have dealt with a lot of negative information concerning nuclear industry: the dire financial situation of AREVA, the questioning about the state of the pressure vessel of the Flamanville EPR or the EDF and Chinese investments in the british Hinkley point project. All these issues have impacted the opinion of the French people about nuclear energy: more people are against nuclear energy but nuclear accident appears to be only the tenth source of concern after unemployment (first) and terrorism. The debate about the energetic transition that will lead to the decrease of the nuclear share in the production of electricity marks the end of a political consensus in favour of the atom. Solar energy is the favorite energy source, more than 55% of the population wish solar energy to achieve a bigger share in the 15 next years while only 32% wish the same thing for wind energy. For most people nuclear energy appears to be necessary to complement renewable energies for at least the next 15-30 years. (A.C.)

    Full Text Available Objectives: Our aim is to describe the current clinical practice related to the management of septic shock (SS. Methods: Review of medical literature using the MEDLINE database. Articles were selected according to their relevancy to the objective and according to the author’s opinion. Summary of the findings: The outcome from SS is dependent on an early recognition and a sequential implementation of time-sensitive goal-directed therapies. The goals of the resuscitation are rapid restoration of micro circulation and improved organ tissue perfusion. Clinical and laboratory markers are needed to assess the adequacy of the treatments. Initial resuscitation involves the use of isotonic solutions (>60ml/kg either crystalloid (normal saline or colloid infusion often followed by vasoactive medications. Altered pharmacokinetics and pharmacodynamics responses dictate that vasoactive agents should be adjusted to achieve predetermined goals. An assessment of central venous pressure complements clinical and serological findings to tailor therapies. Elective airway instrumentation and mechanical ventilation as well as adjunctive therapy with stress dose of corticosteroid are indicated in selected populations. In neonates, a special attention to the presence of electrolyte imbalance and increase pulmonary vascular resistance needs to be considered early. Conclusions: Septic shock hemodynamic is a changing process that requires frequent assessment and therapeutic adjustments.

    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

    The Delhi State Drug Policy was adopted in 1994 following which the first Essential Medicines List (EML) was developed in 1996. The Delhi State Essential Medicines Formulary was brought out in 1997. A need was felt to revise the formulary to match with the EML as the EML is renewed every 2 years. A survey was undertaken to elicit the opinions of the doctors practicing in the state on the usefulness of the formulary before revising and printing the updated version. The survey covered dispensaries, 10-20 bedded hospitals, 100-bedded hospitals and two tertiary care hospitals. Discussions were focused on questionnaires on attitudes toward adopting Essential Medicines Formulary using a 10-point scale. Of the 200 doctors approached, only 90 doctors completed the questionnaire. Sixty-nine respondents (76.6%) had received the copy of the formulary. Most practitioners welcomed the formulary and were satisfied with the coverage and selection of the medicines. Most respondents (76.9%) agreed that a well-developed formulary would improve the quality of the public health care system, although they had reservations about the authority, relevance and effect on professional autonomy. About 74% of the respondents used the formulary in clinical practice as a source of medicine information, which makes its regular revision necessary.

    Gun violence and control issues have become serious public health problems. This study gathered the opinions from 419 college students from a Midwestern University. Participants were asked about beliefs about purchasing assault weapons, beliefs about bringing handguns to college campuses and beliefs about contributing factors that lead to gun violence. Participants completed surveys online. The findings showed that overall 54 % of respondents believed that military assault weapons should be banned and 53 % agree that teachers should be allowed to carry a registered handgun on campus. There were statistically significant differences between males and females on these issues. For instance, females believed military assault weapons and high capacity magazines should be banned more than 1.9 times (p = .004) p gun violence were decline in parenting and family values (17 %), gang involvement (14 %), bullying (13.8 %) and guns being easy to obtain (13.8 %). Limitations and implications for policy work are discussed.

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

    Rotavirus (RV) infection is the main cause of severe acute gastroenteritis (GE) in the pediatric population and has a major impact in both developing and industrialized countries. The reduction of severe RVGE cases, followed by death or hospitalization, is considered the main benefit of RV vaccination, even though its implementation often faces obstacles. In Italy, the recently approved National Immunization Plan aims to overcome the differences among regions, offering a universal free RV vaccination. The aim of the study was to evaluate the opinions on benefit and acceptability of RV vaccination related to the perception of the burden of RV disease. Data were collected from 108 physicians in 2015 by a questionnaire consisting of 12 questions; some answers were compared with those obtained with a similar tool in 2011. The majority of respondents (76.2%) was convinced of the benefit of the vaccine and 57.4% recommended it routinely, but more than half indicated a <25% adherence to RV vaccination among their patients. As the main reasons of vaccine refusal, skepticism about the vaccine (60.4%) and its cost (34.1%) were indicated. Our data confirm that more information and counselling are needed to increase RV vaccine coverage.

  20. Understanding Public Opinions from Geosocial Media

    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.

    Full Text Available Background: Only unequivocal evidence confirming the total extent of injury. Biomechanical analysis, objectifications of permanent consequences after injury and objectification, whether such injuries influence life activities of an injured person, should be the basics for preparation of expert medical opinion. To make a necessary distinction from the previous injuries or illnesses that might have influence on current health state of a patient and its treatment, analysis of all medical records of a certain injured person is needed. Therefore this are inevitable steps in preparation of an expert medical opinion. In cases when medical opinion should explain disability of a patient as a consequence of a certain contractual relationship, the contract should be taken into consideration when such opinions is prepared.Methods: 500 opinions have been retrospectively analysed, selected at random out of 3452 opinions, submitted in claims for damages at Zavarovalnica Maribor, d. d., in the period from January 2001 until January 2006. Thirteen typical data have been analysed and evaluated on the basis of objective evidences.Results: On the basis of analyses it has been established that there is a great difference between principles of objectification and the data in analysed opinions. It has been noticed the most obvious deviation in biomechanical analysis (95 %, in records of decreased life activities (90 %, in all medical records of an injured person (65 % and in objectification of permanent consequences after injuries (55 %.Conclusions: As results of analysis demonstrate, there are significant differences in preparations of expert and medical opinions in Slovenia, particularly when basic principles are analysed that need to be considered when writing such opinions. Irrational avoidance of basic principle of objectification, nomination of experts without licence in certain fields of medicine, avoidance of objectification of subjective statements of injured

    2005-01-03

    Basic considerations of lens detection and identification indicate that a wide field survey of the types planned for weak lensing and Type Ia SNe with SNAP are close to optimal for the optical detection of strong lenses. Such a ''piggy-back'' survey might be expected even pessimistically to provide a catalogue of a few thousand new strong lenses, with the numbers dominated by systems of faint blue galaxies lensed by foreground ellipticals. After sketching out our strategy for detecting and measuring these galaxy lenses using the SNAP images, we discuss some of the scientific applications of such a large sample of gravitational lenses: in particular we comment on the partition of information between lens structure, the source population properties and cosmology. Understanding this partitioning is key to assessing strong lens cosmography's value as a cosmological probe.

    1988-01-01

    Existence of a strong coupling phase in QED has been suggested in solutions of the Schwinger-Dyson equation and in Monte Carlo simulation of lattice QED. In this article we recapitulate the previous arguments, and formulate the problem in the modern framework of the renormalization theory, Wilsonian renormalization. This scheme of renormalization gives the best understanding of the basic structure of a field theory especially when it has a multi-phase structure. We resolve some misleading arguments in the previous literature. Then we set up a strategy to attack the strong phase, if any. We describe a trial; a coupled Schwinger-Dyson equation. Possible picture of the strong coupling phase QED is presented. (author)

  6. Continuous Opinion Dynamics Under Bounded Confidence:. a Survey

    Science.gov (United States)

    Lorenz, Jan

    Models of continuous opinion dynamics under bounded confidence have been presented independently by Krause and Hegselmann and by Deffuant et al. in 2000. They have raised a fair amount of attention in the communities of social simulation, sociophysics and complexity science. The researchers working on it come from disciplines such as physics, mathematics, computer science, social psychology and philosophy. In these models agents hold continuous opinions which they can gradually adjust if they hear the opinions of others. The idea of bounded confidence is that agents only interact if they are close in opinion to each other. Usually, the models are analyzed with agent-based simulations in a Monte Carlo style, but they can also be reformulated on the agent's density in the opinion space in a master equation style. The contribution of this survey is fourfold. First, it will present the agent-based and density-based modeling frameworks including the cases of multidimensional opinions and heterogeneous bounds of confidence. Second, it will give the bifurcation diagrams of cluster configuration in the homogeneous model with uniformly distributed initial opinions. Third, it will review the several extensions and the evolving phenomena which have been studied so far, and fourth it will state some open questions.

    2015-04-01

    Networks were successfully applied to describe complex systems, such as brain, climate, processes in society. Recently a socio-physical problem of opinion-dynamics was studied using network techniques. We present the toy-model of opinion-formation based on the physical model of advection-diffusion. We consider spreading of the opinion on the fixed subject, assuming that opinion on society is binary: if person has opinion then the state of the node in the society-network equals 1, if the person doesn't have opinion state of the node equals 0. Opinion can be spread from one person to another if they know each other, or in the network-terminology, if the nodes are connected. We include into the system governed by advection-diffusion equation the external field to model such effects as for instance influence from media. The assumptions for our model can be formulated as the following: 1.the node-states are influenced by the network structure in such a way, that opinion can be spread only between adjacent nodes (the advective term of the opinion-dynamics), 2.the network evolution can have two scenarios: -network topology is not changing with time; -additional links can appear or disappear each time-step with fixed probability which requires adaptive networks properties. Considering these assumptions for our system we obtain the system of equations describing our model-dynamics which corresponds well to other socio-physics models, for instance, the model of the social cohesion and the famous voter-model. We investigate the behavior of the suggested model studying "waiting time" of the system, time to get to the stable state, stability of the model regimes for different values of model parameters and network topology.

    Conceived in the 1960s, the Landsat program has experienced six successful missions that have contributed to an unprecedented 39-year record of Earth Observations that capture global land conditions and dynamics. Incremental improvements in imaging capabilities continue to improve the quality of Landsat science data, while ensuring continuity over the full instrument record. Landsats 5 and 7 are still collecting imagery. The planned launch of the Landsat Data Continuity Mission in December 2012 potentially extends the Landsat record to nearly 50 years. The U.S. Geological Survey (USGS) Landsat archive contains nearly three million Landsat images. All USGS Landsat data are available at no cost via the Internet. The USGS is committed to improving the content of the historical Landsat archive though the consolidation of Landsat data held in international archives. In addition, the USGS is working on a strategy to develop higher-level Landsat geo- and biophysical datasets. Finally, Federal efforts are underway to transition Landsat into a sustained operational program within the Department of the Interior and to authorize the development of the next two satellites — Landsats 9 and 10.

    The role of Australian rural radiographers in radiographic interpretation, communication and disclosure of their radiographic opinion with a specific focus on plain film radiography was examined in a two phase, exploratory interpretive study. Data were collected using questionnaires and interviews and analysed thematically. This reports one of the key themes identified in the thematic data analysis. ‘Disclosure of Radiographic Opinion to Patients’ comprises the three interrelated sub-themes Acting Ethically, Selective Disclosure and Filtered Truth. It is wholly concerned with the ways in which rural radiographers choose to disclose their radiographic opinion to patients. Without a clear picture of where they stand medico-legally, rural radiographers draw on experience and a strong ethical framework as the basis for these complex decisions. Rural radiographers frame their disclosures to patients in a manner that is governed by the diagnostic, therapeutic and emotional impact the information disclosed may have on the patient. Disclosure to patients was found to be selective, often diagnostically vague and ethically filtered

    The beam-beam interaction puts a strong limit on the luminosity of the high energy storage ring colliders. At the interaction points, the electromagnetic fields generated by one beam focus or defocus the opposite beam. This can cause beam blowup and a reduction of luminosity. An accurate simulation of the beam-beam interaction is needed to help optimize the luminosity in high energy colliders.

    Full Text Available To study the sentiment diffusion of online public opinions about hot events, we collected people's posts through web data mining techniques. We calculated the sentiment value of each post based on a sentiment dictionary. Next, we divided those posts into five different orientations of sentiments: strongly positive (P, weakly positive (p, neutral (o, weakly negative (n, and strongly negative (N. These sentiments are combined into modes through coarse graining. We constructed sentiment mode complex network of online public opinions (SMCOP with modes as nodes and the conversion relation in chronological order between different types of modes as edges. We calculated the strength, k-plex clique, clustering coefficient and betweenness centrality of the SMCOP. The results show that the strength distribution obeys power law. Most posts' sentiments are weakly positive and neutral, whereas few are strongly negative. There are weakly positive subgroups and neutral subgroups with ppppp and ooooo as the core mode, respectively. Few modes have larger betweenness centrality values and most modes convert to each other with these higher betweenness centrality modes as mediums. Therefore, the relevant person or institutes can take measures to lead people's sentiments regarding online hot events according to the sentiment diffusion mechanism.

    2014-01-01

    Peer tutoring is a well-researched and established method of learning defined as 'a medical student facilitating the learning of another medical student'. While it has been adopted in many medical schools, other schools may be reluctant to embrace this approach. The attitude of the teaching staff, responsible for organizing and or teaching students in an undergraduate medical course to formal peer teaching will affect how it is introduced and operationalized. This study elicits faculty opinions on how best to introduce peer tutoring for medical students. Structured telephone interviews were recorded, transcribed and analyzed using thematic analysis. The interviews were with medically qualified staff responsible for organizing or teaching undergraduate medical students at a New Zealand medical school. Six questions were posed regarding perceived advantages and disadvantages of peer tutoring and how the school and staff could support a peer-tutoring scheme if one was introduced. Staff generally supported the peer tutoring concept, offering a safe environment for learning with its teachers being so close in career stage to the learners. They also say disadvantages when the student-teachers imparted wrong information and when schools used peer tutoring to justify a reduction in teaching staff. Subjects felt that faculty would be more accepting of peer tutoring if efforts were made to build staff 'buy in' and empowerment, train peer tutors and introduce a solid evaluation process. Staff of our school expressed some concerns about peer tutoring that are not supported in the literature, signaling a need for better communication about the benefits and disadvantages of peer tutoring.

    Full Text Available Public opinion plays a vital role in a democracy, as democracies are, by nature responsive to the people. In South Africa, public participation is entrenched in the Constitution. Despite this, the spate of service delivery protests in South Africa in recent years would appear to indicate that the government is out of touch with the opinions of the South African citizens. Public  transport  policy  in  South  Africa  is  described  by  a  number  of  documents,  mainly the  White  Paper  on  National  Transport  Policy,  Moving  South  Africa  and,  more  recently, the National Development Plan. An annual survey of 1000 South Africans is conducted to gauge opinion on transport related matters. The purpose of this article was to compare the current public transport policies (as stated above and the public opinion on public transport (as gauged by the survey in order to determine the extent to which these are aligned. The results  show  that  current  public  transport  policy  is  relatively  strongly  aligned  with  the public transport needs of the South African population, however, concerns regarding public transport such as mobility, accessibility, affordability and safety have not yet to be addressed satisfactorily.

    The continuous evolution and development of experimental techniques is at the basis of any fundamental achievement in modern physics. Strongly correlated systems (SCS), more than any other, need to be investigated through the greatest variety of experimental techniques in order to unveil and crosscheck the numerous and puzzling anomalous behaviors characterizing them. The study of SCS fostered the improvement of many old experimental techniques, but also the advent of many new ones just invented in order to analyze the complex behaviors of these systems. Many novel materials, with functional properties emerging from macroscopic quantum behaviors at the frontier of modern research in physics, chemistry and materials science, belong to this class of systems. The volume presents a representative collection of the modern experimental techniques specifically tailored for the analysis of strongly correlated systems.

    There is an ongoing debate about harm and benefit of e-cigarettes, usage of which has rapidly increased in recent years. By separating non-commercial (organic) tweets from commercial tweets, we seek to evaluate the general public's attitudes towards e-cigarettes. We collected tweets containing the words 'e-cig', 'e-cigarette', 'e-liquid', 'vape', 'vaping', 'vapor' and 'vaporizer' from 23 July to 14 October 2015 (n=757 167). A multilabel Naïve Bayes model was constructed to classify tweets into 5 polarities (against, support, neutral, commercial, irrelevant). We further analysed the prevalence of e-cigarette tweets, geographic variations in these tweets and the impact of socioeconomic factors on the public attitudes towards e-cigarettes. Opinions from organic tweets about e-cigarettes were mixed (against 17.7%, support 10.8% and neutral 19.4%). The organic-against tweets delivered strong educational information about the risks of e-cigarette use and advocated for the general public, especially youth, to stop vaping. However, the organic-against tweets were outnumbered by commercial tweets and organic-support tweets by a ratio of over 1 to 3. Higher prevalence of organic tweets was associated with states with higher education rates (r=0.60, psocial networks could be highly influential to the general public, especially youth. Further educational campaigns should include measuring their effectiveness. Published by the BMJ Publishing Group Limited.

  5. Turning the tide of public opinion on nuclear power

    International Nuclear Information System (INIS)

    Cohen, B.L.

    1997-01-01

    Until the early 1970s, the tide of public opinion in the United States was strongly in favor of nuclear power. New power plants were coming on line frequently, and in 1973-74, there were close to 40 new orders per year for new reactors in the United States. Official government projections estimated 1000 operating reactors by the year 2000. Fuel reprocessing, plutonium recycle, and breeder reactor development were also proceeding smoothly and rapidly. But, in the mid-1970s, the tide suddenly turned against the nuclear industry. How did this come about? In the late 1960s, energetic and idealistic young people who had never experienced economic insecurity or World Wars came of age. Environmentalism was an attractive outlet for their activity in most of the Western world. In the United States, opposition to the Vietnam War, in which these young people had a personal stake, was even more popular at first, but by the early 1970s, Vietnam was winding down, and they turned also to Environmentalism. Numerous environmental groups started up, aided heavily by the favorable connotation of the very word open-quotes environmentalistclose quotes in the public mind. Their organizational experience, political savvy, and media connections gained from their antiwar protests were powerful assets. But the groups needed specific targets to attack, and they soon found that nuclear power was well-suited for that purpose. Here was a new technology, coming on at a very rapid pace. To the public, radiation was highly mysterious, and people were well aware that it could be dangerous. And, the word danger had taken on a new meaning. Previous generations were well acquainted with death and were much less averse to risk-taking than the generation of the 1970s

    We show that the fermion mass spectrum may naturally be understood in terms of flavour democratic fixed points in supersymmetric theories which have a large domain of attraction in the presence of "strong unification". Our approach provides an alternative to the approximate Yukawa texture zeroes of the Froggatt-Nielsen mechanism. We discuss a particular model based on a broken gauged $SU(3)_L\\times SU(3)_R$ family symmetry which illustrates our approach.

    2004-12-01

    Although xenotransplantation is still in an experimental phase, it is presented herein as a possible solution to the organ shortage. However, there are few data concerning how the general public would accept treatment with animal organs, especially after recent incidents of infections of animal origin, such as "avian influenza" or "SARS disease." The aim of this study was to determine the attitude of the general public toward xenotransplantation of organs. Using an opinion survey, a study was performed on a random sample of 250 subjects in an urban setting. The questionnaire was administered by personnel from the regional transplant coordination center. Completion of the form was self-directed and anonymous for each respondent. The attitude toward donation of human and animal organs was evaluated by analyzing different psychosocial variables that may influence this attitude. A descriptive statistical study was performed using Student's t test and the chi-square test. Ninety-eight percent of respondents completed the survey (n=245). As for human donation, 60% are in favor of cadaveric donation with 21% are in favor of living donation, a rate that increases to 74% if it is for a living partner. As for animal donation, if the results were similar to those obtained with human organs, 74% (n=181) would accept an animal organ if they needed it, as opposed to 18% (n=45) who were undecided and 8% (n=19) against (P <.005). Analysis of variables that influence attitudes toward xenotransplantation showed that this attitude was more positive among those having had a previous experience with transplantation (P=.028) and those having a positive attitude toward cadaveric donation (P=.007). Factors traditionally related to cadaveric donation, such as manipulation of the body or pro-social activities, showed no influence. In the population studied, a positive attitude toward xenotransplantation was greater than toward cadaveric donation, assuming the results of these two types of

  12. Public authority control strategy for opinion evolution in social networks

    Chen, Xi; Xiong, Xi; Zhang, Minghong; Li, Wei

    2016-08-01

    This paper addresses the need to deal with and control public opinion and rumors. Existing strategies to control public opinion include degree, random, and adaptive bridge control strategies. In this paper, we use the HK model to present a public opinion control strategy based on public authority (PA). This means utilizing the influence of expert or high authority individuals whose opinions we control to obtain the optimum effect in the shortest time possible and thus reach a consensus of public opinion. Public authority (PA) is only influenced by individuals' attributes (age, economic status, and education level) and not their degree distribution; hence, in this paper, we assume that PA complies with two types of public authority distribution (normal and power-law). According to the proposed control strategy, our experiment is based on random, degree, and public authority control strategies in three different social networks (small-world, scale-free, and random) and we compare and analyze the strategies in terms of convergence time (T), final number of controlled agents (C), and comprehensive efficiency (E). We find that different network topologies and the distribution of the PA in the network can influence the final controlling effect. While the effect of PA strategy differs in different network topology structures, all structures achieve comprehensive efficiency with any kind of public authority distribution in any network. Our findings are consistent with several current sociological phenomena and show that in the process of public opinion/rumor control, considerable attention should be paid to high authority individuals.

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

    Yamamoto, Yoshihiro

    2015-01-01

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

  16. Atoms in strong laser fields

    International Nuclear Information System (INIS)

    L'Huillier, A.

    2002-01-01

    When a high-power laser focuses into a gas of atoms, the electromagnetic field becomes of the same magnitude as the Coulomb field which binds a 1s electron in a hydrogen atom. 3 highly non-linear phenomena can happen: 1) ATI (above threshold ionization): electrons initially in the ground state absorb a large number of photons, many more than the minimum number required for ionization; 2) multiple ionization: many electrons can be emitted one at a time, in a sequential process, or simultaneously in a mechanism called direct or non-sequential; and 3) high order harmonic generation (HHG): efficient photon emission in the extreme ultraviolet range, in the form of high-order harmonics of the fundamental laser field can occur. The theoretical problem consists in solving the time dependent Schroedinger equation (TDSE) that describes the interaction of a many-electron atom with a laser field. A number of methods have been proposed to solve this problem in the case of a hydrogen atom or a single-active electron atom in a strong laser field. A large effort is presently being devoted to go beyond the single-active approximation. The understanding of the physics of the interaction between atoms and strong laser fields has been provided by a very simple model called ''simple man's theory''. A unified view of HHG, ATI, and non-sequential ionization, originating from the simple man's model and the strong field approximation, expressed in terms of electrons trajectories or quantum paths is slowly emerging.

    The scalar strong interaction hadron theory, SSI, is a first principles' and nonlocal theory at quantum mechanical level that provides an alternative to low energy QCD and Higgs related part of the standard model. The quark-quark interaction is scalar rather than color-vectorial. A set of equations of motion for mesons and another set for baryons have been constructed. This book provides an account of the present state of a theory supposedly still at its early stage of development. This work will facilitate researchers interested in entering into this field and serve as a basis for possible future development of this theory.

  2. Strong Plate, Weak Slab Dichotomy

    Petersen, R. I.; Stegman, D. R.; Tackley, P.

    2015-12-01

    Models of mantle convection on Earth produce styles of convection that are not observed on Earth.Moreover non-Earth-like modes, such as two-sided downwellings, are the de facto mode of convection in such models.To recreate Earth style subduction, i.e. one-sided asymmetric recycling of the lithosphere, proper treatment of the plates and plate interface are required. Previous work has identified several model features that promote subduction. A free surface or pseudo-free surface and a layer of material with a relatively low strength material (weak crust) allow downgoing plates to bend and slide past overriding without creating undue stress at the plate interface. (Crameri, et al. 2012, GRL)A low viscosity mantle wedge, possibly a result of slab dehydration, decouples the plates in the system. (Gerya et al. 2007, Geo)Plates must be composed of material which, in the case of the overriding plate, are is strong enough to resist bending stresses imposed by the subducting plate and yet, as in the case of the subducting plate, be weak enough to bend and subduct when pulled by the already subducted slab. (Petersen et al. 2015, PEPI) Though strong surface plates are required for subduction such plates may present a problem when they encounter the lower mantle.As the subducting slab approaches the higher viscosity, lower mantle stresses are imposed on the tip.Strong slabs transmit this stress to the surface.There the stress field at the plate interface is modified and potentially modifies the style of convection. In addition to modifying the stress at the plate interface, the strength of the slab affects the morphology of the slab at the base of the upper mantle. (Stegman, et al 2010, Tectonophysics)Slabs that maintain a sufficient portion of their strength after being bent require high stresses to unbend or otherwise change their shape.On the other hand slabs that are weakened though the bending process are more amenable to changes in morphology. We present the results of

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

    Science.gov (United States)

    Donner, S. D.; McDaniel, J.

    2010-12-01

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

  4. Physics of Strongly Coupled Plasma

    Energy Technology Data Exchange (ETDEWEB)

    Kraeft, Wolf-Dietrich [Universitat Rostock (Germany)

    2007-07-15

    Strongly coupled plasmas (or non-ideal plasmas) are multi-component charged many-particle systems, in which the mean value of the potential energy of the system is of the same order as or even higher than the mean value of the kinetic energy. The constituents are electrons, ions, atoms and molecules. Dusty (or complex) plasmas contain still mesoscopic (multiply charged) particles. In such systems, the effects of strong coupling (non-ideality) lead to considerable deviations of physical properties from the corresponding properties of ideal plasmas, i.e., of plasmas in which the mean kinetic energy is essentially larger than the mean potential energy. For instance, bound state energies become density dependent and vanish at higher densities (Mott effect) due to the interaction of the pair with the surrounding particles. Non-ideal plasmas are of interest both for general scientific reasons (including, for example, astrophysical questions), and for technical applications such as inertially confined fusion. In spite of great efforts both experimentally and theoretically, satisfactory information on the physical properties of strongly coupled plasmas is not at hand for any temperature and density. For example, the theoretical description of non-ideal plasmas is possible only at low densities/high temperatures and at extremely high densities (high degeneracy). For intermediate degeneracy, however, numerical experiments have to fill the gap. Experiments are difficult in the region of 'warm dense matter'. The monograph tries to present the state of the art concerning both theoretical and experimental attempts. It mainly includes results of the work performed in famous Russian laboratories in recent decades. After outlining basic concepts (chapter 1), the generation of plasmas is considered (chapter 2, chapter 3). Questions of partial (chapter 4) and full ionization (chapter 5) are discussed including Mott transition and Wigner crystallization. Electrical and

    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

    The structures and motions of quasi-2-dimensional strongly coupled dust Coulomb clusters with particle number N from few to hundreds in a cylindrical rf plasma trap are studied and compared with the results from the molecular dynamic simulation using more ideal models. Shell structures with periodic packing in different shells and intershell rotational motion dominated excitations are observed at small N. As N increases, the boundary has less effect, the system recovers to the triangular lattice with isotropic vortex type cooperative excitations similar to an infinite N system except the outer shell region. The above generic behaviors are mainly determined by the system symmetry and agree with the simulation results. The detailed interaction form causes minor effect such as the fine structure of packing

    In this work we, using Mellin’s transform combined with the Gaussian large-scale boundary condition, calculate probability densities (PDFs) of velocity increments P(δu,r), velocity derivatives P(u,r) and the PDF of the fluctuating dissipation scales Q(η,Re), where Re is the large-scale Reynolds number. The resulting expressions strongly deviate from the Log-normal PDF P(δu,r) often quoted in the literature. It is shown that the probability density of the small-scale velocity fluctuations includes information about the large (integral) scale dynamics which is responsible for the deviation of P(δu,r) from P(δu,r). An expression for the function D(h) of the multifractal theory, free from spurious logarithms recently discussed in [U. Frisch, M. Martins Afonso, A. Mazzino, V. Yakhot, J. Fluid Mech. 542 (2005) 97] is also obtained.

    Full Text Available The PISA tests applied by OECD in 2012 had a strong impact in Colombia because of the low scores obtained by students . The news had more coverage in the press. In order to establish how they can shape public opinion on the subject because of the manner and direction in which they were addressed, were analyzed news , editorials, opinion columns and letters from readers (total 39 information units appeared in two Colombian daily newspapers in two and a half months. Recognizing the evaluation as a social fact , the analysis focused around : quality of information sources used , breadth of perspective on the evidence by reference to the evidence and formulate action alternatives . The basic conclusions are : the sources of information to give opinion are very limited, they aren´t criticized and the focus is on the scores ; these show a very negative picture that is extended to all the country's education ; teachers are largely responsible for the failure. The opinion that the media contribute to form is negative.

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

    The Government decides to respect the 'Framework for Nuclear Energy Policy', which was decided by the Atomic Energy Commission on October 11th, 2005, as a basic principle for the nuclear energy policy and promote research, development and utilization of nuclear science and engineering. The Atomic Energy Commission asked the public to comment on the draft and held Public Hearings at five different venues. The Planning Council finalized the draft, taking the 1717 opinions from 701 citizens thus gathered into the consideration. Reading the public attitude with public opinions had been conducted by the author, which showed a large percentage of the consent to the policy and, at the same time, the necessity for the nation to make more efforts to communicate with the public in simple and more concise terms or listen to the public, and also to gain the public trust through education and public relations. The pros and cons both commented that the mass media was not fair. (T. Tanaka)

    Prostate cancer is one of the most frequently diagnosed cancer among men. Because of the long latency period of prostate cancer, and the economic burden and morbidity associated with its treatment, there is a strong rationale for interventions to reduce the risk of developing this malignancy. The terms „prevention“ or „chemo prevention“ refers to efforts to prevent or delay the development of cancer by taking medicines, vitamins or other agents. There are many agents that may decrease the risk of prostate cancer. It requires careful study of the agents in specific populations to determine whether risk is reduced, magnitude of the risk reduction and the spectrum of side effects associated with the agent. The ideal preventive agent will not significantly alter quality of life, is inexpensive, safe, well tolerated, and effective. The purpose of this article is to review recent developments in the field of prostate cancer prevention. (author)

    Rotavirus is the leading cause of dehydration and hospitalization due to gastroenteritis (GE) in young children. Almost all children are affected by the age of 5 years. Two safe and effective rotavirus vaccines are available for clinical use in Canada. In the context where rotavirus vaccination is recommended, but not publicly funded, we have assessed paediatricians' knowledge, attitudes and beliefs (KAB) regarding rotavirus disease and its prevention by vaccination. A self-administered anonymous questionnaire based upon the Health Belief Model and the Analytical framework for immunization programs was mailed to all 1852 Canadian paediatricians. The response rate was 50%. The majority of respondents rated consequences of rotavirus infection for young patients as moderate. Sixty-six percent considered that rotavirus disease occur frequently without vaccination and 62% estimated that the disease generates a significant economic burden. Sixty-nine percent of respondents considered rotavirus vaccines to be safe and 61%, to be effective. The reduction of severe GE cases was seen as the main benefit of rotavirus vaccination, while the risk of adverse events was the principal perceived barrier. Fifty-three percent (53%) indicated a strong intention to recommend rotavirus vaccines. In multivariate analysis, main determinant of paediatricians' intention to recommend rotavirus vaccines was the perceived health and economic burden of rotavirus diseases (partial R(2)=0.49, p<0.0001). More than half of surveyed paediatricians were willing to recommend rotavirus vaccines to their patients, but the proportion of respondents who had a strong intention to do so remains low when compared to several other new vaccines. As with other new vaccines, rotavirus vaccine uptake risks to remain low in Canada as long as it is not publicly funded. Copyright © 2011 Elsevier Ltd. All rights reserved.

    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.

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

    International Nuclear Information System (INIS)

    1996-09-01

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

    In health care, it is widely known that evidence-based medicine (EBM) has a significant impact on clinical practice, and opinion leaders can enhance the clinician's application of EBM in various disciplines. In this article, we examine the existence and impact of opinion leaders in craniofacial surgery as well as barriers to evidence-based practice. We compiled the answers of an Internet questionnaire, which was sent to 102 craniofacial surgeons. Our results demonstrate that opinion leaders most definitely can be identified in craniofacial surgery. They are tightly connected to their field's social network and promote EBM. In this survey, 44% of craniofacial surgeons reported that their greatest obstacle to clinical decision making in the management of nonsyndromic synostosis was lack of surgical consensus. In addition, craniofacial surgeons stated that EBM and opinion leaders are the most influential factors that caused them to change their management of craniosynostosis. We expect that the use of opinion leaders can further enhance the uptake of EBM in craniofacial surgery.

    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.

  19. Are public opinion polls self-fulfilling prophecies?

    Directory of Open Access Journals (Sweden)

    David Rothschild

    2014-08-01

    Full Text Available Psychologists have long observed that people conform to majority opinion, a phenomenon sometimes referred to as the ‘bandwagon effect’. In the political domain people learn about prevailing public opinion via ubiquitous polls, which may produce a bandwagon effect. Newer types of information – published probabilities derived from prediction market contract prices and aggregated polling summaries – may have similar effects. Consequently, polls can become self-fulfilling prophecies whereby majorities, whether in support of candidates or policies, grow in a cascading manner. Despite increased attention to whether the measurement of public opinion can itself affect public opinion, the existing empirical literature is surprisingly limited on the bandwagon effects of polls. To address this gap, we conducted an experiment on a diverse national sample in which we randomly assigned people to receive information about different levels of support for three public policies. We find that public opinion as expressed through polls affects individual-level attitudes, although the size of the effect depends on issue characteristics.

    Abiding to the law is, in some cases, a delicate balance between the rights of different players. Re-using health records is such a case. While the law grants reuse rights to public administration documents, in which health records produced in public health institutions are included, it also grants privacy to personal records. To safeguard a correct usage of data, public hospitals in Portugal employ jurists that are responsible for allowing or withholding access rights to health records. To help decision making, these jurists can consult the legal opinions issued by the national committee on public administration documents usage. While these legal opinions are of undeniable value, due to their doctrine contribution, they are only available in a format best suited from printing, forcing individual consultation of each document, with no option, whatsoever of clustered search, filtering or indexing, which are standard operations nowadays in a document management system. When having to decide on tens of data requests a day, it becomes unfeasible to consult the hundreds of legal opinions already available. With the objective to create a modern document management system, we devised an open, platform agnostic system that extracts and compiles the legal opinions, ex-tracts its contents and produces metadata, allowing for a fast searching and filtering of said legal opinions.

  5. Improving the Held and Karp Approach with Constraint Programming

    Science.gov (United States)

    Benchimol, Pascal; Régin, Jean-Charles; Rousseau, Louis-Martin; Rueher, Michel; van Hoeve, Willem-Jan

    Held and Karp have proposed, in the early 1970s, a relaxation for the Traveling Salesman Problem (TSP) as well as a branch-and-bound procedure that can solve small to modest-size instances to optimality [4, 5]. It has been shown that the Held-Karp relaxation produces very tight bounds in practice, and this relaxation is therefore applied in TSP solvers such as Concorde [1]. In this short paper we show that the Held-Karp approach can benefit from well-known techniques in Constraint Programming (CP) such as domain filtering and constraint propagation. Namely, we show that filtering algorithms developed for the weighted spanning tree constraint [3, 8] can be adapted to the context of the Held and Karp procedure. In addition to the adaptation of existing algorithms, we introduce a special-purpose filtering algorithm based on the underlying mechanisms used in Prim's algorithm [7]. Finally, we explored two different branching schemes to close the integrality gap. Our initial experimental results indicate that the addition of the CP techniques to the Held-Karp method can be very effective.

    1990-01-01

    This paper examines the properties of stellar systems that have recently undergone a strong tidal shock, i.e., a shock which removes a significant fraction of the particles in the system, and where the shocked system has a much smaller mass than the producer of the tidal field. N-body calculations of King models shocked in a variety of ways are performed, and the consequences of the shocks are investigated. The results confirm the prediction of Jaffe for shocked systems. Several models are also run where the tidal forces on the system are constant, simulating a circular orbit around a primary, and the development of tidal radii under these static conditions appears to be a mild process which does not dramatically affect material that is not stripped. The tidal radii are about twice as large as classical formulas would predict. Remnant density profiles are compared with a sample of elliptical galaxies, and the implications of the results for the development of stellar populations and galaxies are considered. 38 refs

    2006-01-01

    Our friend and colleague John Strong was cruelly taken from us by a brain tumour on 31 July, a few days before his 65th birthday. John started his career and obtained his PhD in a group from Westfield College, initially working on experiments at Rutherford Appleton Laboratory (RAL). From the early 1970s onwards, however, his research was focused on experiments in CERN, with several particularly notable contributions. The Omega spectrometer adopted a system John had originally developed for experiments at RAL using vidicon cameras (a type of television camera) to record the sparks in the spark chambers. This highly automated system allowed Omega to be used in a similar way to bubble chambers. He contributed to the success of NA1 and NA7, where he became heavily involved in the electronic trigger systems. In these experiments the Westfield group joined forces with Italian colleagues to measure the form factors of the pion and the kaon, and the lifetime of some of the newly discovered charm particles. Such h...

    At the McGee Creek, California, site, 3-component strong-motion accelerometers are located at depths of 166 m, 35 m and 0 m. The surface material is glacial moraine, to a depth of 30.5 m, overlying homfels. Accelerations were recorded from two California earthquakes: Round Valley, M L 5.8, November 23, 1984, 18:08 UTC and Chalfant Valley, M L 6.4, July 21, 1986, 14:42 UTC. By separating out the SH components of acceleration, we were able to determine the orientations of the downhole instruments. By separating out the SV component of acceleration, we were able to determine the approximate angle of incidence of the signal at 166 m. A constant phase velocity Haskell-Thomson model was applied to generate synthetic SH seismograms at the surface using the accelerations recorded at 166 m. In the frequency band 0.0 - 10.0 Hz, we compared the filtered synthetic records to the filtered surface data. The onset of the SH pulse is clearly seen, as are the reflections from the interface at 30.5 m. The synthetic record closely matches the data in amplitude and phase. The fit between the synthetic accelerogram and the data shows that the seismic amplification at the surface is a result of the contrast of the impedances (shear stiffnesses) of the near surface materials

    Full Text Available In this article, I analyze public opinion about the 2006 Mexican presidential election in the context of the post–election conflict. My goal is to determine which individual–level variables influenced opinions about the post–election conflict. The analysis focuses on individual positions about the election fairness, confidence in the electoral Tribunal, claims for a full recount, and the public's stands on street protests and mobilization, among others. I use the Mexican component of the Comparative National Election Project (CNEP, conducted for the first time in Mexico in 2006 as a two–wave, preelection and postelection, panel design. The results highlight the importance of political predispositions in the analysis of public opinion in Mexico.

  10. Advertising and Irreversible Opinion Spreading in Complex Social Networks

    Candia, Julián

    Irreversible opinion spreading phenomena are studied on small-world and scale-free networks by means of the magnetic Eden model, a nonequilibrium kinetic model for the growth of binary mixtures in contact with a thermal bath. In this model, the opinion of an individual is affected by those of their acquaintances, but opinion changes (analogous to spin flips in an Ising-like model) are not allowed. We focus on the influence of advertising, which is represented by external magnetic fields. The interplay and competition between temperature and fields lead to order-disorder transitions, which are found to also depend on the link density and the topology of the complex network substrate. The effects of advertising campaigns with variable duration, as well as the best cost-effective strategies to achieve consensus within different scenarios, are also discussed.

    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)

    2012-01-01

    Recently, significant attention has been devoted to opinion dynamics in social networks, in which all the relationships between individuals are assumed as positive ones (i.e. friend, altruism or trust). However, many realistic social networks include negative relationships (i.e. enemy or distrust) as well as positive ones. In order to find the dynamical behavior of opinion spreading in signed networks, we propose a model taking into account the impacts of positive and negative relationships. Based on this model, we analyze the dynamical process and provide a detailed mathematical analysis for identifying the threshold of opinion spreading in homogeneous networks with signed relationships. By performing numerical simulations for the threshold in three different signed networks, we find that the theoretical and numerical results are in good agreement, confirming the correctness of our exact solution.

    1995-01-01

    Nirex is a company financed by the UK nuclear industry to dispose of intermediate and some long-lived low-level radioactive waste. The company has no responsibility for high-level radioactive waste. Most low-level waste is disposed of at a shallow site owned by BNFL, one of Nirex's shareholders. At Nirex, we use opinion research in a number of ways: as a map to guide communications programmes; to set baselines and targets to isolate issues of concern to our publics. The Company carries out market research covering three key audiences: the general public, politicians, and journalists. For Nirex, opinion research is a map. It guides our communication programmes in dealing with our key audiences. Without it, we would be driving blind. Opinion research allows us to isolate key issues for communication. It also allows us to measure performance and to see which initiatives are successful and which are not

    Full Text Available Since the past half century, expert testimony has played an increasingly important role in Chinese litigation. As the amount of expert testimony has grown, the issues about its admissibility and scientific foundation related to evidence are becoming to be questioned commonly. Since eighteenth central committee (China adopted the decision of the Central Committee of China on several important issues in promoting the legal system, the evidence was redefined to become the predominance in the whole proceeding. This article reviews the expert knowledge implicit in the opinions. It argues that the expert opinions ask judges to be aware of the role of communicationg between participants. Expert opinion is not only gained from laboratory, but also socially constructed in the rational expression and communication, which requir us think logically in terms of legal perceptions of science and expert knowledge in the empirical world.

  15. Moral opinion polarization and the erosion of trust.

    2016-07-01

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

    El Jammal, Marie-Helene; Rollinger, Francois; Mur, Emmanuelle; Schuler, Matthieu; Tchernia, Jean-Francois

    2013-01-01

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

    2009-02-01

    The Zaller theory of opinion formation is reformulated with one free parameter μ, which measures the largest possible ideological distance which can be made by a citizen in one mental step. Our numerical results show the transient effects: (i) the political awareness, measured by the number of received messages, increases with time first exponentially, later linearly; (ii) for small μ correlations are present between previously and newly received messages; (iii) these correlation lead to a hyperdiffusion effect in the space of attitudes of messages. Citizens with small μ are more prone to extremal opinions.

    generalized trust, we focus on opinion polarization as another potential impact factor on trust. In more detail, we investigate the extent to which polarization over morally charged issues such as homsexuality, abortion and euthanasia affects individuals' likelihood to trust others. We hypothesize that moral...... issues have a natural tendency to divide societies' opinions into opposing poles and, thus, to challenge social cohesion in modern civil societies. Based on hierarchical analyses of the fifth wave of the World Values Survey (WVS) - comprising a sample of 39 countries - our results reveal that individuals...

  1. A Second Opinion: A Case Narrative on Clinical Ethics Mediation.

    2015-01-01

    Contrasting traditional and common forms of ethics consultation with bioethics mediation, I describe the case of a "second opinion" consultation in the care of a patient with advanced cancer for whom treatment was futile. While the initial ethics consultation, performed by a colleague, led to a recommendation that some may deem ethical, the process failed to involve key stakeholders and failed to explore the underlying values and reasons for the opinions voiced by various stakeholders. The process of mediation ultimately led to creative solutions in which all stakeholders could reach consensus on a plan of care. Copyright 2015 The Journal of Clinical Ethics. All rights reserved.

  2. Strongly interacting photons and atoms

    Alge, W.

    1999-05-01

    This thesis contains the main results of the research topics I have pursued during the my PhD studies at the University of Innsbruck and partly in collaboration with the Institut d' Optique in Orsay, France. It is divided into three parts. The first and largest part discusses the possibility of using strong standing waves as a tool to cool and trap neutral atoms in optical cavities. This is very important in the field of nonlinear optics where several successful experiments with cold atoms in cavities have been performed recently. A discussion of the optical parametric oscillator in a regime where the nonlinearity dominates the evolution is the topic of the second part. We investigated mainly the statistical properties of the cavity output of the three interactive cavity modes. Very recently a system has been proposed which promises fantastic properties. It should exhibit a giant Kerr nonlinearity with negligible absorption thus leading to a photonic turnstile device based on cold atoms in cavity. We have shown that this model suffers from overly simplistic assumptions and developed several more comprehensive approaches to study the behavior of this system. Apart from the division into three parts of different contents the thesis is divided into publications, supplements and invisible stuff. The intention of the supplements is to reach researchers which work in related areas and provide them with more detailed information about the concepts and the numerical tools we used. It is written especially for diploma and PhD students to give them a chance to use the third part of our work which is actually the largest one. They consist of a large number of computer programs we wrote to investigate the behavior of the systems in parameter regions where no hope exists to solve the equations analytically. (author)

  3. Topics in strong Langmuir turbulence

    Skoric, M.M.

    1981-01-01

    This thesis discusses certain aspects of the turbulence of a fully ionised non-isothermal plasma dominated by the Langmuir mode. Some of the basic properties of strongly turbulent plasmas are reviewed. In particular, interest is focused on the state of Langmuir turbulence, that is the turbulence of a simple externally unmagnetized plasma. The problem of the existence and dynamics of Langmuir collapse is discussed, often met as a non-linear stage of the modulational instability in the framework of the Zakharov equations (i.e. simple time-averaged dynamical equations). Possible macroscopic consequences of such dynamical turbulent models are investigated. In order to study highly non-linear collapse dynamics in its advanced stage, a set of generalized Zakharov equations are derived. Going beyond the original approximation, the author includes the effects of higher electron non-linearities and a breakdown of slow-timescale quasi-neutrality. He investigates how these corrections may influence the collapse stabilisation. Recently, it has been realised that the modulational instability in a Langmuir plasma will be accompanied by the collisionless-generation of a slow-timescale magnetic field. Accordingly, a novel physical situation has emerged which is investigated in detail. The stability of monochromatic Langmuir waves in a self-magnetized Langmuir plasma, is discussed, and the existence of a novel magneto-modulational instability shown. The wave collapse dynamics is investigated and a physical interpretation of the basic results is given. A problem of the transient analysis of an interaction of time-dependent electromagnetic pulses with linear cold plasma media is investigated. (Auth.)

  4. Promoting Strong Written Communication Skills

    2015-12-01

    The reason that an improvement in the quality of technical writing is still needed in the classroom is due to the fact that universities are facing challenging problems not only on the technological front but also on the socio-economic front. The universities are actively responding to the changes that are taking place in the global consumer marketplace. Obviously, there are numerous benefits of promoting strong written communication skills. They can be summarized into the following six categories. First, and perhaps the most important: The University achieves learner satisfaction. The learner has documented verbally, that the necessary knowledge has been successfully acquired. This results in learner loyalty that in turn will attract more qualified learners.Second, quality communication lowers the cost per pupil, consequently resulting in increased productivity backed by a stronger economic structure and forecast. Third, quality communications help to improve the cash flow and cash reserves of the university. Fourth, having high quality communication enables the university to justify the need for high costs of tuition and fees. Fifth, better quality in written communication skills result in attracting top-quality learners. This will lead to happier and satisfied learners, not to mention greater prosperity for the university as a whole. Sixth, quality written communication skills result in reduced complaints, thus meaning fewer hours spent on answering or correcting the situation. The University faculty and staff are thus able to devote more time on scholarly activities, meaningful research and productive community service. References Boyer, Ernest L. (1990).

    The first objective of this study is to shed light on the public opinion on age-related degradation at nuclear power plants, namely, on how the general public recognizes or views age-related degradation, which is a safety-related issue and one of the factors contributing to accidents and failures which occur at nuclear power plants. The second objective is to look into the impacts of the accident at Mihama Unit 3, which was caused by a failure to check on the piping wall thickness, on the public opinion on age-related degradation. The first survey was conducted in August 2003, followed by the second survey in October 2004, two months after the accident. The surveys found that the age-related degradation is being perceived by people as one of the risk factors that affect the safety of nuclear power plants. The characteristics of the citizens' perceptions toward age-related degradation in the form of piping cracks are that: (a) many respondents feel uneasy but a relatively few people consider that nuclear operators are technologically capable of coping with this problem; (b) many people believe that radioactivity may be released; and (c) numerous respondents consider that signs of cracks must be thoroughly detected through inspections, while on the other hand, a large percentage of the respondents attribute the accident to improper inspections/maintenance. Based on these results, the government and nuclear operators are expected to give most illuminating explanation on the current situation of and remedial measures against age-related degradation at nuclear power plants. As for the effects of the Mihama-3 accident on the public opinion on age-related degradation, it was revealed that the accident has not so significantly affected the general view for the safety of nuclear power plants, but has newly or strongly aroused people's consciousness of two of the risk factors - improper inspections/maintenance and the age-related degradation of piping.

    Although legally anchored, there are no empirical results from German second opinion programs. In this study, various aspects within a population of a second opinion program are examined. In this study patients were analyzed who sought a second opinion in the period from August 2011 to December 2016. Differences in patient characteristics, differentiated by agreement of first and second opinion, were analyzed using multivariate logistic regression. Patients' satisfaction and quality of life were examined one, three and six months after obtaining the second opinion. In total, 1,414 patients sought a second opinion. Most frequent medical indications were the knee (38.7 %), the back (26.8 %), the hip (11.7 %), and the shoulder (10.2 %). Except for the indication (p=0.035), no patient characteristic had influence on the conformation of the second opinion. Approximately two out of three initial recommendations were not confirmed by the specialists. 89 % of the patients were satisfied or very satisfied with the second opinion and the service offered. The second opinion offers patients the opportunity to seek an additional independent medical opinion and thus provide support for decision making. Further research is needed to examine the reasons for the high discrepancies between the first and second opinions. Copyright © 2018. Published by Elsevier GmbH.

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

  11. Public opinion and nuclear power decision-making

    International Nuclear Information System (INIS)

    Benson, B.

    1991-01-01

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

    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.

  19. Entropy based classifier for cross-domain opinion mining

    Directory of Open Access Journals (Sweden)

    Jyoti S. Deshmukh

    2018-01-01

    Full Text Available In recent years, the growth of social network has increased the interest of people in analyzing reviews and opinions for products before they buy them. Consequently, this has given rise to the domain adaptation as a prominent area of research in sentiment analysis. A classifier trained from one domain often gives poor results on data from another domain. Expression of sentiment is different in every domain. The labeling cost of each domain separately is very high as well as time consuming. Therefore, this study has proposed an approach that extracts and classifies opinion words from one domain called source domain and predicts opinion words of another domain called target domain using a semi-supervised approach, which combines modified maximum entropy and bipartite graph clustering. A comparison of opinion classification on reviews on four different product domains is presented. The results demonstrate that the proposed method performs relatively well in comparison to the other methods. Comparison of SentiWordNet of domain-specific and domain-independent words reveals that on an average 72.6% and 88.4% words, respectively, are correctly classified.

    To investigate the frequency of traumatisation, suicidality and given diagnoses in expert opinions on asylum seekers and to describe the sociodemographic characteristics of this population. The psychiatric expert opinions on asylum seekers, furnished in an 8-year-period at Hannover Medical School, were analysed retrospectively for qualitative and quantitative characteristics. 62 psychiatric expert opinions on asylum seekers were included in this study. The asylum seekers originated from 18 different countries, mainly from Turkey and former Yugoslavia. Most expert opinions were given in secondary asylum procedures, i. e. after the initial asylum request had been rejected. The asylum seekers reported on traumatisation in 82.3 %. The most frequently reported forms of traumatisation were rape in female, and torture in male persons. According to ICD-10 or DSM-IV-R criteria posttraumatic stress disorder (PTSD) was the most frequent diagnosis (74.1 %) in this study. The second most common diagnoses were depressive disorders (ICD-10: F32.x in 33.9 % and ICD-10: F33.x in 25.9 %). Suicidal tendency was found in 56.5 % of the asylum seekers. Cultural differences, language barriers, a heavy burden by psychological symptoms, and clinical severity are difficulties in the process of psychiatric assessment of refugees in legal asylum procedures. © Georg Thieme Verlag KG Stuttgart · New York.

  20. Serbian public opinion on child imagination and its correlates

    Directory of Open Access Journals (Sweden)

    Maksić Slavica

    2008-01-01

    Full Text Available Child imagination is considered in developmental theories as a desirable precondition for later creative production, though in everyday use, imagination is viewed as fantasy, unreal, not practical and not important. The topic of interest in this paper is public opinion of imagination as the quality that can be encouraged to learn at home and the factors which influence this opinion. The data for the analysis were collected from the Third and Fourth Wave of World Values Survey. The findings suggest that imagination has a very low status among other child qualities which have to be supported. The increase in interest for imagination in the world and in Europe between the Third and Fourth Wave of the survey can indicate larger compliance with the actual demands of educational reform for democratization of education and encouragement of creativity of the young. Stagnation of child imagination status in the opinion of Serbian respondents is understandable in the framework of social crisis which happened at the time when the survey was conducted. The preference of imagination is positively correlated with respondents' postmaterialist orientation and educational level, but negatively with their age. The implications of findings for nurturing creativity in formative period are discussed. It is concluded that the school is invited to offer special programs to compensate for public opinion effects.

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

    2005-10-01

    The dynamics of opinion formation in large groups of people is a complex nonlinear phenomenon whose investigation is just beginning. Both collective behavior and personal views play an important role in this mechanism. In the present work we mimic the dynamics of opinion formation of a group of agents, represented by two states ±1 , as a stochastic response of each agent to the opinion of his/her neighbors in the social network and to feedback from the average opinion of the whole. In the light of recent studies, a scale-free Barabási-Albert network has been selected to simulate the topology of the interactions. A turbulentlike dynamics, characterized by an intermittent behavior, is observed for a certain range of the model parameters. The problem of uncertainty in decision taking is also addressed both from a topological point of view, using random and targeted removal of agents from the network, and by implementing a three-state model, where the third state, zero, is related to the information available to each agent. Finally, the results of the model are tested against the best known network of social interactions: the stock market. A time series of daily closures of the Dow-Jones index has been used as an indicator of the possible applicability of our model in the financial context. Good qualitative agreement is found.

  13. The influence of persuasion in opinion formation and polarization

    Science.gov (United States)

    La Rocca, C. E.; Braunstein, L. A.; Vazquez, F.

    2014-05-01

    We present a model that explores the influence of persuasion in a population of agents with positive and negative opinion orientations. The opinion of each agent is represented by an integer number k that expresses its level of agreement on a given issue, from totally against k=-M to totally in favor k = M. Same-orientation agents persuade each other with probability p, becoming more extreme, while opposite-orientation agents become more moderate as they reach a compromise with probability q. The population initially evolves to (a) a polarized state for r=p/q\\gt 1 , where opinions' distribution is peaked at the extreme values k=+/- M , or (b) a centralized state for r < 1, with most opinions around k=+/- 1 . When r \\gg 1 , polarization lasts for a time that diverges as r^M \\ln N , where N is the population's size. Finally, an extremist consensus (k = M or -M ) is reached in a time that scales as r^{-1} for r \\ll 1 .

    2014-05-27

    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.

    Energy Technology Data Exchange (ETDEWEB)

    Pathak, Neetu; Henry, Michael J.; Volkova, Svitlana

    2017-03-29

    Social media is a powerful data source for researchers interested in understanding population-level behavior, having been successfully leveraged in a number of different application areas including flu and illness prediction models, detecting civil unrest, and measuring public sentiment towards a given topic of interest within the public discourse. In this work, we present a study of a large collection of Twitter data centered on the social conversation around global cli- mate change during the UN Climate Change Conference, held in Paris, France during December 2015 (COP21). We first developed a mechanism for distinguishing between personal and non-personal accounts. We then analyzed demographics and emotion and opinion dynamics over time and location in order to understand how the different user types converse around meaningful topics on social media. This methodology offers an in-depth insight into the behavior and opinions around a topic where multiple distinct narratives are present, and lays the groundwork for future work in studying narratives in social media.

    Background The predictD study developed and validated a risk algorithm for predicting the onset of major depression in primary care. We aimed to explore the opinion of patients about knowing their risk for depression and the values and criteria upon which these opinions are based. Methods A maximum variation sample of patients was taken, stratified by city, age, gender, immigrant status, socio-economic status and lifetime depression. The study participants were 52 patients belonging to 13 urban health centres in seven different cities around Spain. Seven Focus Groups (FGs) were given held with primary care patients, one for each of the seven participating cities. Results The results showed that patients generally welcomed knowing their risk for depression. Furthermore, in light of available evidence several patients proposed potential changes in their lifestyles to prevent depression. Patients generally preferred to ask their General Practitioners (GPs) for advice, though mental health specialists were also mentioned. They suggested that GPs undertake interventions tailored to each patient, from a “patient-centred” approach, with certain communication skills, and giving advice to help patients cope with the knowledge that they are at risk of becoming depressed. Conclusions Patients are pleased to be informed about their risk for depression. We detected certain beliefs, attitudes, values, expectations and behaviour among the patients that were potentially useful for future primary prevention programmes on depression. PMID:24646951

We aimed to explore the opinion of patients about knowing their risk for depression and the values and criteria upon which these opinions are based.A maximum variation sample of patients was taken, stratified by city, age, gender, immigrant status, socio-economic status and lifetime depression. The study participants were 52 patients belonging to 13 urban health centres in seven different cities around Spain. Seven Focus Groups (FGs were given held with primary care patients, one for each of the seven participating cities.The results showed that patients generally welcomed knowing their risk for depression. Furthermore, in light of available evidence several patients proposed potential changes in their lifestyles to prevent depression. Patients generally preferred to ask their General Practitioners (GPs for advice, though mental health specialists were also mentioned. They suggested that GPs undertake interventions tailored to each patient, from a "patient-centred" approach, with certain communication skills, and giving advice to help patients cope with the knowledge that they are at risk of becoming depressed.Patients are pleased to be informed about their risk for depression. We detected certain beliefs, attitudes, values, expectations and behaviour among the patients that were potentially useful for future primary prevention programmes on depression.

    In the Higher School of Agronomic and Forestry Engineering of the University of Cordoba, a collective project conceived as an 'ecosystem to support and accompany entrepreneurs' has been proposed. The approach aims to spread and consolidate the entrepreneurial spirit and to respond to the demands of possible stakeholders involved in the whole process of training, as well as the subsequent integration of graduates into the labour market. Putting into practice this initiative, which involves multiple actors, is a complex and difficult task. For this reason, prior to its implementation, the authors considered it necessary to listen to main stakeholders' opinions and evaluate their degree of commitment and the requirements they consider important for the viability and sustainability of the initiative. This paper focuses on the faculty's opinions, gathered by means of a survey conducted with the entire faculty (N = 128, response rate = 45%) and semi-structured interviews held with 20 members of the School board. The results suggest that there is a general consensus on the suitability of this collective project and that there is a core of teachers willing to get involved. Evidently, guidelines need to be produced to facilitate taking on such tasks. However, the main drawbacks are related with the conflict between formal requirements of professor professional profile and the steps needed to establish the ecosystem.

    Objectives To collect and analyze Kentucky pharmacists' opinions of the effectiveness of current methamphetamine precursor controls, to analyze proposed legislation to make pseudoephedrine (PSE) a legend drug, and to analyze the potential impact of such legislation on pharmacy practice and patients. Design Descriptive, nonexperimental survey study. Setting Kentucky; June through October 2012. Participants 431 Kentucky community pharmacists. Intervention Mailed survey. Main outcome measures Perceived efficacy of current methamphetamine precursor controls, anticipated impact on individual pharmacy practices and patients of proposed legislation to make PSE available by prescription only, and current opinions about the proposed legislation. Results Analysis of 431 community pharmacists showed that approximately 77% believed proposed legislation to make PSE available by prescription only would be effective in reducing methamphetamine abuse and methamphetamine-related laboratory incidents, with 56.2% indicating support for the proposed legislation. Pharmacists practicing in chain pharmacies were 2.9 times more likely to support the legislation than pharmacists practicing in independent pharmacies. Additional factors influencing pharmacist support included Kentucky region of practice, anticipated impact on time spent on PSE activities, pharmacy profit, methamphetamine abuse, and methamphetamine-related laboratory incidents. Pharmacists practicing in regions of Kentucky associated with higher methamphetamine abuse appear to more strongly support the proposed legislation. Conclusion Pharmacists are at the frontline of PSE distribution. Gaining a better understanding of issues surrounding the distribution of PSE will enhance the likelihood that future legislation may be crafted to reduce methamphetamine production, laboratory incidents, and abuse while minimizing inconvenience and cost.

    Alcohol-related problems at professional sporting events are of increasing concern and alarming reports are often reported in international media. Although alcohol consumption increases the risk for interpersonal violence, it is viewed as a focal element of large football events. Sweden has a long tradition of high public support for strict alcohol-control policies. However, little is known about public opinions on alcohol intoxication and the support for interventions to decrease intoxication at football events. The current study explored the public opinion towards alcohol use, intoxication and alcohol policies at professional football matches in Sweden. A cross-sectional design was utilized and a random general population sample of 3503 adult Swedish residents was asked to participate in a web survey during 2016 (response rate 68%). In total, 26% of the respondents supported alcohol sales at football events. Over 90% reported that obviously intoxicated spectators should be denied entrance or evicted from arenas. The support for regulations limiting alcohol availability varied with background factors such as gender, alcohol use and frequency of football event attendance. There is a strong public consensus for strategies and policies to reduce alcohol sales and intoxication levels at football matches. This public support has implications for our preventive efforts and will facilitate the implementation of strategies and policy changes.

    To examine Korean public opinions toward alcohol control measures on availability, advertisement, drink-driving and pricing policy, and how the views on alcohol control policy vary by demographics, drinking patterns and attitude to drinking environments. The study used national-based, cross-sectional data collected in 2012 as part of the International Alcohol Control study. 2510 people (M: 1163, F: 1261) aged 15-65 and living in geographically diverse regions of Korea completed the questionnaire asking the support of 12 alcohol control measures. Generally, targeted measures (purchase age of 20 and drink-driving) were more popular than universal (availability, advertisement and price) among Koreans. Gender, age, marital status, drinking patterns and attitude to drinking environments related to alcohol use of young and heavy drinkers were strong predictors of the opinions on most of the alcohol control measures. It was daily/weekly drinkers who opposed most restrictions on alcohol availability and price and the support from individuals who are more aware of problems with drinking in public place was outstanding in every control measure. These findings should be taken into account by Korean policy-makers as they formulate an alcohol policy for the country. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Support for marijuana (cannabis) legalization is increasing in the US, and state-level marijuana policies are rapidly changing. Research is needed to examine correlates of opinions toward legalization among adolescents approaching adulthood as they are at high risk for use. Data were examined from a national representative sample of high school seniors in the Monitoring the Future study (years 2007-2011; N = 11,594) to delineate correlates of opinions toward legalization. A third of students felt marijuana should be entirely legal and 28.5% felt it should be treated as a minor violation; 48.0% felt that if legal to sell it should be sold to adults only, and 10.4% felt it should be sold to anyone. Females, conservatives, religious students, and those with friends who disapprove of marijuana use tended to be at lower odds for supporting legalization, and Black, liberal, and urban students were at higher odds for supporting more liberal policies. Recent and frequent marijuana use strongly increased odds for support for legalization; however, 16.7% of non-lifetime marijuana users also reported support for legalization. Findings should be interpreted with caution as state-level data were not available, but results suggest that support for marijuana legalization is common among specific subgroups of adolescents.

    Given its serious impacts on the public’s health, air pollution in China is a matter of strong public concern, particularly in reference to malodorous waste gas. Petition letters related to atmospheric pollution accounted for about 40% of the total petition cases. However, scholarly views differ on whether the Chinese government responds to public opinion on the environment and seeks to improve its environmental governance behavior. For this study, data from national surveys on the public’s environmental satisfaction administered during the period 2011–2015 were analyzed to determine whether the public’s dissatisfaction with the state of the environment in a given year resulted in increased investments by provincial governments in pollution governance during the following year. The study’s findings revealed that governmental behavior in response to public opinion on the environment was selective within the field of environmental governance, with provincial governments being inclined to invest more in waste gas pollution control than in water pollution control. Furthermore, results from this study show that the Chinese government tends to put more efforts into the environmental field where it could more easily achieve short-term benefits. PMID:29401701

    Attitudes toward sexuality are a key variable for sexual health. It is really important for psychology and education to have adapted and validated questionnaires to evaluate these attitudes. Therefore, the objective of this research was to adapt, validate and calculate the equivalence of the Colombia Sexual Opinion Survey as compared to the same survey from Spain. To this end, a total of eight experts were consulted and 1,167 subjects from Colombia and Spain answered the Sexual Opinion Survey, the Sexual Assertiveness Scale, the Massachusetts General Hospital-Sexual Functioning Questionnaire, and the Sexuality Scale. The evaluation was conducted by online and the results show adequate qualitative and quantitative properties of the items, with adequate reliability and external validity and compliance with the strong invariance between the two countries. Consequently, the Colombia Sexual Opinion Survey is a valid and reliable scale and its scores can be compared with the ones from the Spain survey, with minimum bias. PMID:27627114
