    In this thesis we will question the perceptions of industrial risks in the occidental world at the beginning of the 21. century. For this purpose we will try to understand how concepts such as sustainable development, precautionary principle, liability, or even zero-risk bias have progressively developed around a thought model based on the scientific rationality. This model is now undermined by its incapacity to fully address the issues it raises and completely avoid the potential risks. However, despite consistent weaknesses, it remains a reference value moulded by past accidents which have led to the making of laws aiming mainly at defining liability and protecting those who are held liable. Thus, public information becomes a requirement for democracy and the protection of this thought model. In this context, the protagonists at stake are security-conscious, economical and political lobbies that constantly redefine the limits of risk acceptance. We come to the realization that our lifestyle and value system remain unchallenged even though undergoing a crisis. The specificity of this research lies into the importance we give to the local approach, dealing with registered Seveso sites and nuclear plants located in Indre et Loire. We have polled five categories of respondents through interviews or questionnaires in order to understand their opinion regarding situations involving technological risks. The result of this survey helps us understand and set the levels of risk acceptance that they define with regard to the industrial risks and show the complexity of a situation involving political stakes, environmental pressures, a profit-driven economy and security constraints, in a vague and complex context. This work gives us a contrasted picture of today's perceptions of risks. (author)

    To determine perceptions of acceptable conducts amongst under and postgraduate optometry students and to compare them with students from other disciplines. Students (under/postgraduate) of optometry (n=156) and other courses (n=54) from University of Minho participated in a voluntary online questionnaire about perception of conducts, classifying as acceptable or unacceptable 15 academic or professional scenarios. 210 questionnaires were analyzed. Differences in perceptions were found between optometry under and postgraduates in scenario 5, Chi-square(2,156)=4.3, p=0.038, and scenario 7, Chi-square(2,156)=7.0, p=0.008 (both with cheating more acceptable for postgrads). Differences between under and postgraduates from other courses were found in scenario 9 (taking supplies from classroom more acceptable for undergrads), Chi-square(1,54)=5.0, p=0.025, and scenario 14 (forging a signature more acceptable for postgrads), Chi-square(1,54)=3.9, p=0.046. Differences between optometry and other courses undergraduates were observed in scenario 2 (plagiarism more acceptable for optometry undergrads), Chi-square(1,154)=8.3, p=0.004 and scenario 9 (taking supplies from classroom more acceptable for other undergrads), chi-square(1,54)=7.8, p=0.005. Differences between optometry and other courses postgraduates were observed in scenario 7, Chi-square(1,56)=5.8, p=0.016, scenario 10 (both with cheating more acceptable for optometry postgrads), chi-square(1,54)=8.1, p=0.004 and scenario 14 (forging a signature more acceptable for other postgrads), Chi-square(1,54)=6.1, p=0.026. Academic misconducts were mainly considered more acceptable than professional misconducts. Our results show that perceptions of acceptable conducts amongst optometry students are not very different from other students, and, against our initial prediction, do not show a general change in misconduct perception when students become more mature.

    2017-01-01

    Existing literature in people’s attitude toward nanotechnology and acceptance of nanotechnology applications has generally investigated the impact of factors at the individual or context levels. While this vast body of research is very informative, a comprehensive understanding of how attitude toward nanotechnology are formed and factors influencing the acceptance of nanotechnology are elusive. This paper proposes an exploratory nanotechnology perception-attitude-acceptance framework (Nano-PAAF) to build a systematic understanding of the phenomenon. The framework proposes that perceptions of risks and benefits of nanotechnology are influenced by cognitive, affective, and sociocultural factors. The sociodemographic factors of consumers and contextual factors mitigate the influence of cognitive, affective, and sociocultural factors on the perception of risks and benefits. The perceived risks and benefits in turn influence people’s attitude toward nanotechnology, which then influences acceptance of nanotechnology products. This framework will need further development over time to incorporate emerging knowledge and is expected to be useful for researchers, decision and policy makers, industry, and business entities.

    2016-02-03

    To examine published research which explores the perception and acceptability of microneedle technology for immunisation and to investigate the suitability of this technology for paediatric use. A series of keywords and their synonyms were combined in various combinations and permutations using Boolean operators to sequentially search four databases (PubMed, Web of Science, Embase and CINAHL). Following removal of duplications and irrelevant results, 12 research articles were included in the final literature review. The opinions of patients, parents, children and healthcare professionals (HCP) were collated. A positive perception and a high level of acceptability predominated. Microneedle technology research has been focussed on demonstrating efficacy with minimal focus on determining HCP/public perception and acceptability for paediatric use, exemplified by the paucity of studies presented in this review. Commercial viability will depend on HCP/public acceptability of microneedle technology. An effort must be made to identify the barriers to acceptance and to overcome them by increasing awareness and education in stakeholder groups pertaining to the paediatric population.

    China's nuclear industry is recently experiencing rapid development, creating a need for research into public perceptions and acceptance of nuclear power. In this paper, we propose a strategy for investigating public perception and acceptance in China, in a continuous and accurate way, and testing the effectiveness of public education in order to find a proper way to improve the perception and acceptance of nuclear energy in China. Questionnaires are conducted separately both before and after public education activities on nuclear energy held in Beijing. Some conclusions and future continuation of this study are also discussed.

    The presented survey was conducted in six European countries as an online study. A total of 2454 subjects participated. Two main research questions were investigated: firstly, how does the cognitive, moral, and affective framing of radio frequency electromagnetic field (RF EMF) exposure perception influence RF EMF risk perception? Secondly, can the deployment of mobile phone base stations have greater acceptance with RF EMF exposure reduction? The findings with respect to the first question clearly indicated that the cognitive framed exposure perception is the main determinant of RF EMF risk perception. The concomitant sensitivity to exposure strength offers an opportunity to improve the acceptance of base stations by exposure reduction. A linear regression analysis supported this assumption: in a fictional test situation, exposure reduction improved the acceptance of base stations, operationalized as the requested distance of the base station from one's own home. Furthermore, subjects with high RF EMF risk perception were most sensitive to exposure reduction. On average, a 70% exposure reduction reduced the requested distance from about 2000 meters to 1000 meters. The consequences for risk communication are discussed.

    2015-06-01

    Unmanned aircraft, or drones, are a rapidly emerging sector of the aviation industry. There has been limited substantive research, however, into the public perception and acceptance of drones. This article presents the results from two surveys of the Australian public designed to investigate (1) whether the public perceive drones to be riskier than existing manned aviation, (2) whether the terminology used to describe the technology influences public perception, and (3) what the broader concerns are that may influence public acceptance of the technology. We find that the Australian public currently hold a relatively neutral attitude toward drones. Respondents did not consider the technology to be overly unsafe, risky, beneficial, or threatening. Drones are largely viewed as being of comparable risk to that of existing manned aviation. Furthermore, terminology had a minimal effect on the perception of the risks or acceptability of the technology. The neutral response is likely due to a lack of knowledge about the technology, which was also identified as the most prevalent public concern as opposed to the risks associated with its use. Privacy, military use, and misuse (e.g., terrorism) were also significant public concerns. The results suggest that society is yet to form an opinion of drones. As public knowledge increases, the current position is likely to change. Industry communication and media coverage will likely influence the ultimate position adopted by the public, which can be difficult to change once established. © 2014 Society for Risk Analysis.

    2014-11-01

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

    The concept of risk cannot be limited to simply knowing the probability of occurrence and the seriousness of the damages caused. It's a matter of social construction and numerous elements contribute towards its perception and acceptability. These elements have been studied for 20 years or so. Some of these elements influence risk perception such as awfulness, unfamiliarity, the number of people exposed to it, other elements influence its acceptance such as individual perceptions, social factors, ethics and equity. Their knowledge allows a better understanding of the evolution of perception and of the risk acceptability in general and transfusion risk in particular.

    Objective: To determine knowledge, perception, and acceptance related to cervical cancer, HPV vaccination and screening for cervical cancer among Indonesian women, particularly in Yogyakarta province. Methods: A convenience sample of 392 women consists of 192 young women, 100 mothers of girls aged 12 – 15 years, and 100 adult women in Yogyakarta province, Indonesia was participated in this study. A self-administered paper-based questionnaire was used to determine demographics characteristics of respondents, as well as their knowledge – perceptionacceptance related to cervical cancer, HPV vaccination, and screening for cervical cancer. Data collection were conducted during December 2013 to March 2014. Descriptive statistics was used to analyze description of demographics characteristics, knowledge, perception, and acceptance; while crosstab analysis using Chi-Square was used to analyze the relationship between demographics characteristics versus knowledge, perception, and acceptance. Results: This study found that knowledge and perception regarding cervical cancer, HPV vaccination, and screening for cervical cancer among women in Indonesia, particularly in Yogyakarta Province were still insufficient, however the acceptance was good. Among female young women, 64% had good knowledge, 62% had positive perception of cervical cancer and HPV vaccination, and 92% tended to accept HPV vaccination. Among mothers of girls aged 12 – 15 years, 44% had good knowledge, 46% had positive perception of cervical cancer and HPV vaccination, and 91% tended to accept HPV vaccination for their daughters. Among adult women, 68% had good knowledge, 57% had positive perception of cervical cancer and screening for cervical cancer, and 90% tended to accept cervical cancer screening. In general, demographics characteristics of having experience and exposure to information had significant relationship with knowledge, perception, and acceptance of HPV vaccination and screening for

    This study was performed to evaluate consumers’ perception and acceptance of selected pork and chicken sausage (budim and chicken sausages, respectively) from Zlatiborac Meat Company. Sensory evaluation was performed by Serbian consumers (n=1157) in three retail stores in Belgrade. Consumers were asked for their preference for taste, salt content and smoke of two sausages and to recognize the kind of meat which was used to make these meat products. Consumers evaluated taste, salt content and smoke flavor of budim and chicken sausages with the highest percentage of the best offered answer. Between 47-55%, 72-76% and 82-84% of consumers evaluated the taste of sausages as good, the salt content as well-balanced and the smoke flavor as balanced, respectively. Tukey’s HSD test was applied to analyze variations of male and female perception and acceptance of analyzed sausages.

    Public acceptance of radioactive waste management alternatives depends in part on public perception of the associated risks. Three aspects of those perceived risks were explored in this study: (1) synthetic measures of risk perception based on judgments of probability and consequences; (2) acceptability of hypothetical radioactive waste policies, and (3) effects of human values on risk perception. Both the work on synthetic measures of risk perception and on the acceptability of hypothetical policies included investigations of three categories of risk: (1) Short-term public risk (affecting persons living when the wastes are created), (2) Long-term public risk (affecting persons living after the time the wastes were created), and (3) Occupational risk (affecting persons working with the radioactive wastes).

    2005-01-01

    Now, public acceptance plays a central role in the nuclear energy. Public concerns on safety and sustainability of nuclear energy, ground nuclear power in many countries and territories to a stop or even a downfall. In this study, an e-learning framework by using Internet, is proposed for public education in order to boost public perception on nuclear energy, which will certainly affect public acceptance toward it. This study aims at investigating public perception and acceptance on nuclear energy in a continuous and accurate manner. In addition, this e-learning framework can promote public perception on nuclear energy by using teaching material with a graphical hierarchy about knowledge of nuclear energy. This web-based e-learning framework mainly consists of two components: (1) an e-learning support module which continuously investigates public perception and acceptance toward nuclear energy and teaches public knowledge about nuclear energy; (2) an updating module which may improve the education materials by analyzing the effect of education or proving the materials submitted by the visitors through Wiki pages. Advantages and future work of this study are also generally described. (author)

We studied to survey basic procedures of deriving this value and to derive an acceptable risk value in Japan by using similar procedures. The basic procedures to derive 10 -5 /y were found as follows; (1) 0.1 percent of annual mortality from all diseases, (2) 0.1 percent of life time risk, (3) one percent of mortality from all causes in each age cohort and (4) corresponding value to 1 mSv annual radiation exposure. From these bases we derived the value of 10 -5 /y as acceptable risk level in Japan. The perception to risk level of 10 -5 /y in conventional life was investigated by means of questionnaires for 1,095 college students living in Tokyo. The risks considered in this study were natural background radiation, coffee, skiing, X-ray diagnosis, spontaneous cancer, passive smoking and air pollution. The most acceptable risk was the risk related with natural background radiation. And the risk of natural background radiation was more easily accepted by the students who had knowledges on natural background radiation. On the other hand, the risk from air pollution or passive smoking was the most adverse one. (author)

    This paper, based on the international research literatures on perception of risks, designs a conceptual model of public perception of nuclear power risk. In this model, it is considered that the public perception of nuclear power risk is a dynamic, complicate and closed system and is a process from subjective perception to objective risk. Based on the features of the public perception of nuclear power risk and multi-faceted dimension influences as discussed, suggestions for the public education for nuclear power acceptance are given in five aspects with indication that the public education for nuclear power acceptance plays an important role in maintaining the public perception of nuclear power risk system.

    Faced with a severe drought, the residents of the regional city of Toowoomba, in South East Queensland, Australia were asked to consider a potable wastewater reuse scheme to supplement drinking water supplies. As public risk perceptions and trust have been shown to be key factors in acceptance of potable reuse projects, this research developed and tested a social-psychological model of trust, risk perceptions and acceptance. Participants (N = 380) were surveyed a few weeks before a referendum was held in which residents voted against the controversial scheme. Analysis using structural equation modelling showed that the more community members perceived that the water authority used fair procedures (e.g., consulting with the community and providing accurate information), the greater their sense of shared identity with the water authority. Shared social identity in turn influenced trust via increased source credibility, that is, perceptions that the water authority is competent and has the community's interest at heart. The findings also support past research showing that higher levels of trust in the water authority were associated with lower perceptions of risk, which in turn were associated with higher levels of acceptance, and vice versa. The findings have a practical application for improving public acceptance of potable recycled water schemes. Copyright © 2014 Elsevier Ltd. All rights reserved.

    We examined event-contingent recording of daily interpersonal interactions in a diagnostically diverse sample of 101 psychiatric outpatients who were involved in a romantic relationship. We tested whether the unique effect of borderline personality disorder (BPD) symptoms on affective responses (i.e., hostility, sadness, guilt, fear, and positive affect) to perceptions of rejection or acceptance differed with one's romantic partner compared with nonromantic partners. BPD symptoms were associated with more frequent perceptions of rejection and less frequent perceptions of acceptance across the study. For all participants, perceptions of rejecting behavior were associated with higher within-person negative affect and lower within-person positive affect. As predicted, in interactions with romantic partners only, those with high BPD symptoms reported heightened hostility and, to a lesser extent, attenuated sadness in response to perceptions of rejection. BPD symptoms did not moderate associations between perceptions of rejection and guilt, fear, or positive affect across romantic and nonromantic partners. For all participants, perceived acceptance was associated with lower within-person negative affect and higher within-person positive affect. However, BPD symptoms were associated with attenuated positive affect in response to perceptions of accepting behavior in interactions with romantic partners only. BPD symptoms did not moderate associations between perceptions of acceptance and any of the negative affects across romantic and nonromantic partners. This study highlights the specificity of affective responses characteristic of BPD when comparisons are made with patients with other personality and psychiatric disorders. Implications for romantic relationship dysfunction are discussed. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

    Full Text Available This paper assesses students’ attitudes towards using tablets, such as the Apple iPad, in university classes. Tablets are found to be a substitute for laptop computers. Students initially expressed a great deal of optimism regarding the technology, and, although their views diminished slightly as they gained experience with using a tablet, their attitude towards the technology remained overwhelmingly positive. Most students experienced an easy transition from using a laptop to using a tablet. Furthermore, once students adopted the tablets in place of their laptops for in-class use, the types of tasks they performed with the tablets differed from the types of tasks they had previously performed with the laptop. Overall, the tablets reduced the incidence of off-task behaviour during lectures such as using chat and social networking applications. Cet article évalue les attitudes des étudiants quant à l’utilisation de tablettes électroniques telles que le iPad d’Apple dans les classes universitaires. Les tablettes sont considérées comme des substituts aux ordinateurs portables. Les étudiants ont d’abord exprimé beaucoup d’optimisme à l’égard de cette technologie, et bien que leur perception se soit légèrement dégradée avec l’expérience de la tablette, leur attitude envers la technologie est restée très positive. La plupart des étudiants ont effectué une transition facile entre l’utilisation d’un ordinateur portable et celle d’une tablette. En outre, une fois que les étudiants ont adopté en classe les tablettes à la place de leurs ordinateurs portables, les types de tâches qu’ils accomplissaient avec les tablettes ont différé des celles qu’ils effectuaient précédemment avec l’ordinateur portable. Dans l’ensemble, les tablettes ont réduit les cas de comportements hors tâche durant les cours, comme l’utilisation du tchat et des réseaux sociaux.

    This report for the Swiss Federal Office of Energy presents in tables and diagrams the results of a survey involving 421 households in Switzerland, about their awareness to energy issues and, in particular, to all what regards wind energy and wind power plants. Globally, 80% of the persons asked for their opinion believe that electric power demand will continue to increase. 66% of them are in favour of increased use of renewable energy sources and would consequently agree with a 10% more expensive end-user energy price. 89% of the persons taking part to the survey approve the installation of wind energy farms in Switzerland. Moreover, statistics indicates that the households living in regions already equipped with wind farms are significantly more favorable to the creation of new wind energy sites than those not living in these regions. By the end of the day, it turns out that the main reasons for accepting wind energy are environmental concerns as well as the fear of being obliged to use nuclear power.

    National physician validation systems aim to ensure lifelong learning through periodic appraisals of physicians' competence. Their effectiveness is determined by physicians' acceptance of and commitment to the system. This study, therefore, sought to explore physicians' perceptions and self-reported acceptance of validation across three different physician validation systems in Europe. Using a constructivist grounded-theory approach, we conducted semi-structured interviews with 32 respiratory specialists from three countries with markedly different validation systems: Germany, which has a mandatory, credit-based system oriented to continuing professional development; Denmark, with mandatory annual dialogs and ensuing, non-compulsory activities; and the UK, with a mandatory, portfolio-based revalidation system. We analyzed interview data with a view to identifying factors influencing physicians' perceptions and acceptance. Factors that influenced acceptance were the assessment's authenticity and alignment of its requirements with clinical practice, physicians' beliefs about learning, perceived autonomy, and organizational support. Users' acceptance levels determine any system's effectiveness. To support lifelong learning effectively, national physician validation systems must be carefully designed and integrated into daily practice. Involving physicians in their design may render systems more authentic and improve alignment between individual ambitions and the systems' goals, thereby promoting acceptance.

    Aujourd'hui, les façons de produire, d'organiser, d'évaluer et d'utiliser les savoirs sont en profond débat. De plus en plus, l'Etat, la société civile et l'économie tentent d'influencer les activités des universités et des laboratoires de recherche. Ces développements mettent à l'épreuve tout à la fois les fondements des systèmes d'enseignement supérieur et de recherche, l'autonomie des institutions scientifiques, la définition des frontières des savoirs et l'acceptation des sciences. Dans des contextes suisses et européens, cet ouvrage s'intéresse aux manières dont les sciences et les technologies sont fabriquées, en analysant leurs institutions et les pratiques. A partir d'une approche relationnelle, les sciences et les technologies sont conçues comme des phénomènes profondément sociaux, culturels et politiques. Une telle démarche déstabilise les visions parfois idéalisées et stéréotypées de la construction des savoirs. Des études de cas détaillées décrivent des phénomè...

    Social risk elicits self-esteem differences in signature social motivations and behaviors during the relationship-initiation process. In particular, the present research tested the hypothesis that lower self-esteem individuals' (LSEs) motivation to avoid rejection leads them to self-protectively underestimate acceptance from potential romantic partners, whereas higher self-esteem individuals' (HSEs) motivation to promote new relationships leads them to overestimate acceptance. The results of 5 experiments supported these predictions. Social risk increased activation of avoidance goals for LSEs on a word-recall task but increased activation of approach goals for HSEs, as evidenced by their increased use of likeable behaviors. Consistent with these patterns of goal activation, even though actual acceptance cues were held constant across all participants, social risk decreased the amount of acceptance that LSEs perceived from their interaction partner but increased the amount of acceptance that HSEs perceived from their interaction partner. It is important to note that such self-esteem differences in avoidance goals, approach behaviors, and perceptions of acceptance were completely eliminated when social risk was removed.

    The authors examined the contribution of maternal acceptance or warmth to children's and adolescents' perceptions of discipline and formation of moral identity. The sample consisted of 93 male and female students from Grades 5, 8, and 10 and their mothers. Students completed measures pertaining to perceived maternal discipline practices and acceptance-rejection, as well as moral identity. A subsample of mothers reported on their accepting or rejecting actions toward their children. Children were more likely to feel accepted, if their mothers used inductive discipline (vs. power assertion and love withdrawal). Perceived acceptance was also related to more favorable discipline evaluations in certain respects. Specifically, inductive discipline recipients who felt accepted also evaluated induction as appropriate and responded to it with positive and guilt-related emotions. Power assertion was evaluated as appropriate among those children who did feel accepted. Finally, among inductive discipline recipients, those who felt accepted also reported higher moral identity.

    Full Text Available Aims: As a prevalent metabolic disease, diabetes can be followed by severe mental outcomes leading to problems affecting the daily life. The aim of the study was to determine the effects of acceptance and commitment-based intervention on illness perception and psychological capital in persons with type II diabetes. Materials & Methods: In the controlled pretest-posttest semi-experimental study, 34 patients with type II diabetes were studied in the Diabetes Clinic of Chamran Hospital of Ferdows City in 2015. The subjects, selected via available sampling method, were randomly divided into two groups including control (n=17 persons and experimental (n=17 persons groups. Data was collected by short illness perception questionnaire (IPQ and Luthans’ psychological capital questionnaire (PCQ. Eight 60-minute acceptance and commitment-base intervention sessions were weekly conducted in experimental group. Data was analyzed by SPSS 18 software using descriptive statistics and covariance analysis test. Findings: The pretest score having been adjusted, the acceptance and commitment-based intervention significantly increases the scores of illness perception and its sub-scales (p=0.0001 except the personal control sub-scale. In addition, it significantly increases the scores of the psychological capital and its sub-scales (p=0.0001 in patients with type II diabetes. Conclusion: The acceptance and commitment-based intervention can considerably improve the illness perception and the psychological capital in persons with type II diabetes.

    Growing awareness of the potential for some energy-related activities to induce earthquakes has created a need to understand how the public evaluates the risks of induced earthquakes versus the benefits of energy development. To address this need, this study presents a web survey that used a between-subjects factorial experimental design to explore the views of 325 U.S. adults, who were asked about their experiences with earthquakes; risk perceptions related to different causes of earthquakes (e.g., natural versus induced); and acceptability of earthquakes depending on the benefits, beneficiaries, and decision making process. The results found that participants had more negative feelings toward induced versus naturally occurring earthquakes. Although they judged no earthquake as “acceptable,” participants rated induced earthquakes significantly less acceptable than naturally occurring ones. Attributing the benefits to the provision of renewable energy or climate change mitigation did not increase induced earthquake acceptability, and no particular beneficiary made earthquakes more acceptable, although private companies as beneficiaries made earthquakes less acceptable. Finally, induced earthquake acceptability was significantly higher when people believed that people like them had a voice in the decision to implement the technology that caused the earthquake, underscoring the importance of public engagement in the development of energy technologies. - Highlights: • Human induced earthquakes were perceived as more negative than natural earthquakes. • Attributing benefits to renewable energy did not increase earthquake acceptability. • Acceptability was highest after a procedurally fair decision making process. • Acceptability was lowest following an expert-driven decision.

    Full Text Available To better understand the relationship between e-learning integration and organizational factors in South Korea, this study explored the influence of employees’ perceptions of organizational climate on their technology acceptances toward e-learning in the workplace of South Korea. Employees’ perceptions of organizational climate was evaluated using Litwin & Stringer’s Organizational Climate Questionnaire (LSOCQ and employees’ technology acceptance toward e-learning was measured by the Unified Theory of Acceptance and Use of Technology (UTAUT. A canonical correlation suggested that employees’ perceived organizational climate can influence their acceptance levels toward e-learning, which implies the importance of addressing organizational issues while integrating e-learning into workplaces in South Korea.

    Full Text Available Introduction: The purpose of this paper is to assess if similar telemedicine services integrated in the management of different chronic diseases are acceptable and well perceived by patients or if there are any negative perceptions. Theory and methods: Participants suffering from different chronic diseases were enrolled in Veneto Region and gathered into clusters. Each cluster received a similar telemedicine service equipped with different disease-specific measuring devices. Participants were patients with diabetes (n = 163, chronic obstructive pulmonary disease (n = 180, congestive heart failure (n = 140 and Cardiac Implantable Electronic Devices (n = 1635. The Service User Technology Acceptability Questionnaire (SUTAQ was initially translated, culturally adapted and pretested and subsequently used to assess patients’ perception of telemedicine. Data were collected after 3 months and after 12 months from the beginning of the intervention. Data for patients with implantable devices was collected only at 12 months. Results: Results at 12 months for all clusters are similar and assessed a positive perception of telemedicine. The SUTAQ results for clusters 2 (diabetes, 5 (COPD and 7 (CHF after 3 months of intervention were confirmed after 12 months. Conclusions: Telemedicine was perceived as a viable addition to usual care. A positive perception for telemedicine services isn’t a transitory effect, but extends over the course of time.

    Young people are spending increasing amounts of time using digital technology and, as such, are at great risk of being involved in cyber bullying as a victim, bully, or bully/victim. Despite cyber bullying typically occurring outside the school environment, the impact of being involved in cyber bullying is likely to spill over to school. Fully 285 11- to 15-year-olds (125 male and 160 female, M age  = 12.19 years, SD  = 1.03) completed measures of cyber bullying involvement, self-esteem, trust, perceived peer acceptance, and perceptions of the value of learning and the importance of school. For young women, involvement in cyber bullying as a victim, bully, or bully/victim negatively predicted perceptions of learning and school, and perceived peer acceptance mediated this relationship. The results indicated that involvement in cyber bullying negatively predicted perceived peer acceptance which, in turn, positively predicted perceptions of learning and school. For young men, fulfilling the bully/victim role negatively predicted perceptions of learning and school. Consequently, for young women in particular, involvement in cyber bullying spills over to impact perceptions of learning. The findings of the current study highlight how stressors external to the school environment can adversely impact young women's perceptions of school and also have implications for the development of interventions designed to ameliorate the effects of cyber bullying.

    Atmospheric pollution has emerged as a major public health issue in China. Public perception and acceptable risk levels of air pollution can prompt individual behavioral changes and play a major role in the public's response to health risks. Therefore, to explore these responses and evaluate what constitutes publicly acceptable concentrations of fine particulate matter (PM 2.5 ), questionnaire surveys were conducted in three representative cities of China: Beijing, Nanjing, and Guangzhou. Great differences in public risk perception were revealed. Public perception of the health effects of air pollution (Effect) and familiarity with it (Familiarity) were significantly higher in the winter than in the summer, and also during severe haze days compared with typical days. The public perception of trust in the government (Trust) was consistent across all conditions. Exposure to severe haze pollution and experiencing harms from it were key factors influencing public willingness to respond to haze. These results reflected individual exposure levels correlating closely with risk perception and acceptance of PM 2.5 . However, a crucial gap exists between public acceptable risk levels (PARL) of air pollution and the policy objectives of the State Council's Action Plan. Thus, policymakers can utilize this study to develop more targeted measures to combat air pollution. Copyright © 2017 Elsevier Inc. All rights reserved.

  17. Perception of Leitmotives in Richard Wagner's Der Ring des Nibelungen

    Directory of Open Access Journals (Sweden)

    David J. Baker

    2017-05-01

    Full Text Available The music of Richard Wagner tends to generate very diverse judgments indicative of the complex relationship between listeners and the sophisticated musical structures in Wagner's music. This paper presents findings from two listening experiments using the music from Wagner's Der Ring des Nibelungen that explores musical as well as individual listener parameters to better understand how listeners are able to hear leitmotives, a compositional device closely associated with Wagner's music. Results confirm findings from a previous experiment showing that specific expertise with Wagner's music can account for a greater portion of the variance in an individual's ability to recognize and remember musical material compared to measures of generic musical training. Results also explore how acoustical distance of the leitmotives affects memory recognition using a chroma similarity measure. In addition, we show how characteristics of the compositional structure of the leitmotives contributes to their salience and memorability. A final model is then presented that accounts for the aforementioned individual differences factors, as well as parameters of musical surface and structure. Our results suggest that that future work in music perception may consider both individual differences variables beyond musical training, as well as symbolic features and audio commonly used in music information retrieval in order to build robust models of musical perception and cognition.

  18. PAGs - Public perception and acceptance

    International Nuclear Information System (INIS)

    Quillin, Robert M.

    1989-01-01

    Full text: While Protective Action Guides or PAGs have been a part of the lexicon of the radiation protection field for several decades, the concept of accepting higher levels of risk under certain situations has not received adequate scrutiny by the general public, the media or elected officials. Consequently there is a question as to how implementation of PAGs would be perceived by the above groups in the event that such implementation became necessary. A personal case in point involves the response of an executive in the food industry. When the concept of selling a food product meeting the PAGs was explained his response was, 'we won't sell a contaminated product, we would dump the unprocessed raw food. Our industry image is that of a natural unadulterated food'. While this may be an isolated view, there is a need to determine what is the perception and consequently what would be the response if PAGs were implemented today. If the response was negative by anyone of the three groups listed previously, then there is an obvious need for a program to assure receptiveness by those concerned. However, this may face formidable obstacles. This is because the terms radiation and radioactive have gained generally negative word associations, e.g. 'deadly' radiation and radioactive 'desert'. The former term was recently heard in a taped presentation at a Museum of Natural History on a completely unrelated subject. The latter term was part of a recent article heading in the Wall Street Journal. Incidentally the article was discussing television. Thus beyond the scientific issues of setting PAGs and the administrative and procedural issues of implementing PAGs there is the issue of society's understanding and acceptance of PAGs. Particularly, how can such understanding and acceptance be achieved in a situation which is associated with an actual or perceived radiation emergency? These are not questions that radiation or agricultural scientists can answer alone. These are

    There is a growing body of research linking children’s positively biased self-perceptions with higher levels of aggression. This study extended this area of research by examining prospective associations of positively biased self-perceptions of peer acceptance with overt and relational aggression. In addition, moderating effects of peer rejection were examined to test the “disputed overestimation hypothesis,” which posits that the link between bias and aggression is limited to children who are rejected by their peers. Using a two-wave longitudinal design, measures of peer-rated and self-perceived peer acceptance and peer-rated overt and relational aggression were obtained for 712 children in 3rd through 5th grades (386 girls and 326 boys). Positively biased perceptions led to increases in relational, but not overt, aggression. This pattern was observed even when the effects of gender, race, peer rejection, and overt aggression on relational aggression were controlled. Contrary to the disputed overestimation hypothesis, the prospective associations between bias and aggression did not vary as a function of children’s peer rejection status, thus supporting the view that positive bias predicts future aggressive behavior, regardless of social status. The results are discussed in terms of the comparability with previous findings and practical implications. PMID:26423823

    The aim of this study was to elucidate whether physicians' illness perceptions correlate with their frustration or resistance to accepting patients with fibromyalgia (FM). In this cross-sectional postal survey, questionnaires were sent to member physicians of the Japan College of Rheumatology and Japan Rheumatism Foundation. Measures collected included the Brief Illness Perception Questionnaire with Causal Attribution, the Illness Invalidation Inventory, and the Difficult Doctor-Patient Relationship Questionnaire (DDPRQ-10). Multiple logistic regression was performed to examine associations between the DDPRQ-10 and resistance to accepting patients with FM for treatment. We analyzed data from 233 physicians who had experience in consulting with patients with FM. Only 44.2 % answered that they wanted to accept additional patients with FM. Physicians' frustration was associated with difficulty controlling symptoms, patients' emotional responses, and causal attribution of FM to patient internal factors. Conversely, lower levels of frustration were associated with causal attributions to biological factors and uncontrollable external factors. However, the "difficult patient" perception did not correlate with resistance to accepting patients with FM. Difficulty controlling symptoms with treatment was the one factor common to both physicians' frustration and resistance to accepting patients with FM. Physicians may hesitate to accept patients with FM not because of the stigmatic image of the "difficult patient," but instead because of the difficulty in controlling the symptoms of FM. Thus, to improve the quality of consultation, physicians must continuously receive new information about the treatments and causes of FM.

  3. Accepted monitoring or endured quarantine? Ebola contacts' perceptions in Senegal.

    During the 2014-2016 West Africa Ebola epidemic, transmission chains were controlled through contact tracing, i.e., identification and follow-up of people exposed to Ebola cases. WHO recommendations for daily check-ups of physical symptoms with social distancing for 21 days were unevenly applied and sometimes interpreted as quarantine. Criticisms arose regarding the use of coercion and questioned contact tracing on ethical grounds. This article aims to analyze contact cases' perceptions and acceptance of contact monitoring at the field level. In Senegal, an imported case of Ebola virus disease in September 2014 resulted in placing 74 contact cases in home containment with daily visits by volunteers. An ethnographic study based on in-depth interviews with all stakeholders performed in September-October 2014 showed four main perceptions of monitoring: a biosecurity preventive measure, suspension of professional activity, stigma attached to Ebola, and a social obligation. Contacts demonstrated diverse attitudes. Initially, most contacts agreed to comply because they feared being infected. They adhered to the national Ebola response measures and appreciated the empathy shown by volunteers. Later, acceptance was improved by the provision of moral, economic, and social support, and by the final lack of any new contamination. But it was limited by the socio-economic impact on fulfilling basic needs, the fear of being infected, how contacts' family members interpreted monitoring, conflation of contacts as Ebola cases, and challenging the rationale for containment. Acceptance was also related to individual aspects, such as the professional status of women and health workers who had been exposed, and contextual aspects, such as the media's role in the social production of stigma. Ethnographic results show that, even when contacts adhere rather than comply to containment through coercion, contact monitoring raises several ethical issues. These insights should contribute to

    This is an exploratory study carrying out qualitative research into the perceptions, attitudes and concerns of elderly persons towards wireless sensor network (WSN) technologies in terms of their application to healthcare. This work aims to provide guidance on the dimensions and items that may be included in the development of a more in-depth questionnaire to further validate the importance of the identified factors as well as the relationships between them. This study aims to contribute to opening up a communication channel between users and researchers, informing the research community in relation to applications and functionalities that users deem as either desirable, inadequate or in need of further development. Focus groups were conducted with elderly individuals who were still living independently. To explore elderly persons' perceptions and thoughts on current wireless sensor network (WSN) technologies and designs, discussion points were designed from concepts identified from various user acceptance theories and models. Participants were given an introduction to explain the functionality and capabilities of WSN and motes and were shown a sample mote, the Crossbow Mica2Dot. Participants were then asked to discuss their perceptions and concerns towards the likelihood of using a WSN-based healthcare system in their home. We have identified sixteen concepts in relation to the elderly participants' perception, concerns and attitudes towards WSN systems. Those concepts were further classified into six themes describing the determinants that may affect an elderly person's acceptance of WSNs for assisting healthcare. Some of our exploratory findings in this study indicate for example that independence is highly valued by elderly people and hence any system or technology that can prolong that independence tends to be highly regarded, that privacy of WSN health data might not be as important as typically considered, and there are also indications that cost may be the

    The value of health information technology (IT) ultimately depends on end users accepting and appropriately using it for patient care. This study examined pediatric intensive care unit nurses' perceptions, acceptance, and use of a novel health IT, the Large Customizable Interactive Monitor. An expanded technology acceptance model was tested by applying stepwise linear regression to data from a standardized survey of 167 nurses. Nurses reported low-moderate ratings of the novel IT's ease of use and low to very low ratings of usefulness, social influence, and training. Perceived ease of use, usefulness for patient/family involvement, and usefulness for care delivery were associated with system satisfaction (R 2  = 70%). Perceived usefulness for care delivery and patient/family social influence were associated with intention to use the system (R 2  = 65%). Satisfaction and intention were associated with actual system use (R 2  = 51%). The findings have implications for research, design, implementation, and policies for nursing informatics, particularly novel nursing IT. Several changes are recommended to improve the design and implementation of the studied IT.

    The aim of the study was to determine the acceptance and perception of Nigerian patients to medical photography. A self-administered questionnaire was distributed among Nigerian patients attending oral and maxillofacial surgery and plastic surgery clinics of 3 tertiary health institutions. Information requested included patients' opinion about consent process, capturing equipment, distribution and accessibility of medical photographs. The use of non-identifiable medical photographs was more acceptable than identifiable to respondents for all purposes (P = 0.003). Most respondents were favourably disposed to photographs being taken for inclusion in the case note, but opposed to identifiable photographs being used for other purposes most especially in medical websites and medical journals. Female respondents preferred non-identifiable medical photographs to identifiable ones (P = 0.001). Most respondents (78%) indicated that their consent be sought for each of the outline needs for medical photography. Half of the respondents indicated that identifiable photographs may have a negative effect on their persons; and the most commonly mentioned effects were social stigmatization, bad publicity and emotional/psychological effects. Most of the respondents preferred the use of hospital-owned camera to personal camera/personal camera-phone for their medical photographs. Most respondents (67.8%) indicated that they would like to be informed about the use of their photographs on every occasion, and 74% indicated that they would like to be informed of the specific journal in which their medical photographs are to be published. In conclusion, non-identifiable rather than identifiable medical photography is acceptable to most patients in the studied Nigerian environment. The use of personal camera/personal camera-phone should be discouraged as its acceptance by respondents is very low. Judicious use of medical photography is therefore advocated to avoid breach of principle of

    Full Text Available This paper presents an empirical study aiming on investigating ODL students’ perception and adoption of SCORM Compliant Learning Object (SCLO. With the increasing use of SCLO in recent years, a better understanding and implementation of effective instructional resources is necessary to meet the diverse needs of ODL students and enhance their learning performance. The eventual usage of relevant stakeholders determines the success of a system. The system is useless if it is not used in the expected way by the potential users even though it is a good system. Therefore, the aim of this research is to examine if ODL students will eventually use SCLO for their learning. The study used TAM as a basis to investigate the relationship of external and internal variables. A survey instrument eliciting responses on a series of Likert-type questions was given to selected ODL undergraduate students. The results of this study confirm that users’ perception has significant effect on the acceptance and adoption of SCLO. The study provides a better understanding of students’ behavior on SCLO and the acceptance model.

    1999-10-01

    The present study analyzed people's risk perception regarding driving a car with studded or non-studded winter tires. Subjects were 252 residents of Sapporo, where a recent municipal ordinance prohibited studded tires, allowing only non-studded ones. Questionnaire data were examined concerning (1) the relationship between risk perception and its acceptance, (2) the effect of an inserted message, which was either positive or negative about the use of non-studded tires, and (3) the role of personal involvement, assessed with Personal Involvement Inventory (Zaichkowsky, 1985), regarding winter driving. Results were as follows: (1) The use of non-studded tires was favorably judged because of social benefit, but subjects hesitated to choose them because of a higher perceived possibility of an accident. (2) The inserted message had significant effects on benefit evaluation and perceived accident possibility. The effects were weaker for drivers who had experienced driving a car with studded tires. And (3) personal involvement had a weak correlation with risk judgements of the present study.

    2013-12-01

    Full Text Available Twelve special education teachers and teacher assistants who have instructional experience using iPads with children with special needs completed a survey that queried their practices and perceptions. In general, teachers and assistants were extremely positive about the value of iPads for children with special needs, particularly for children with autism, attention deficits and limitations of fine motor control. Special education teachers and teacher assistants reported most frequently using iPads to promote student language and literacy skills, although mathematics learning activities were also commonly reported. Enhanced student motivation was the most frequently reported benefit of using tablet computers in school followed by instructional planning advantages. Tablet computers appear to have the potential to be an essential aspect of individual program plans. Teaching tasks might reasonably include downloading and organizing specific applications on specific children’s tablets and professional development might increasingly focus of evaluation of tablet applications. Douze professeurs en éducation spéciale et aides-enseignants utilisant les iPads dans leur enseignement avec des enfants à besoins spéciaux ont rempli un questionnaire relatif à leurs pratiques et à leurs perceptions. En général, les enseignants et les aides-enseignants se sont révélés extrêmement positifs quant à la valeur des iPads pour les enfants à besoins spéciaux, en particulier pour les enfants avec autisme, avec un déficit d’attention et avec un contrôle limité de la motricité fine. Le plus souvent, les enseignants en éducation spéciale et les aides-enseignants ont indiqué avoir utilisé les iPads pour améliorer les compétences linguistiques et de littératie des élèves, bien que des activités d'apprentissage des mathématiques aient aussi été mentionnées fréquemment.

    Aging in place is a preferred and cost-effective living option for older adults. Research indicates that technology can assist with this goal. Information on consumer preferences will help in technology development to assist older adults to age in place. The study aim was to explore the perceptions and preferences of older adults and their family members about a fall risk assessment system. Using a qualitative approach, this study examined the perceptions, attitudes, and preferences of 13 older adults and five family members about their experience living with the fall risk assessment system during five points in time. Themes emerged in relation to preferences and expectations about the technology and how it fits into daily routines. We were able to capture changes that occurred over time for older adult participants. Results indicated that there was acceptance of the technology as participants adapted to it. Two themes were present across the five points in time-safety and usefulness. Five stages of acceptance emerged from the data from preinstallation to 2 years postinstallation. Identified themes, stages of acceptance, and design and development considerations are discussed.

    This paper discusses the concept of sustainability in relation to acceptance of nuclear energy. Acceptance is viewed in terms of public acceptance, industrial acceptance, and internal acceptance/consensus within the nuclear community. It addresses sustainability criteria, the need for innovation, and the different levels of acceptability. The mechanisms of risk perception are discussed along with the technological consequences from risk perception mechanisms leading to specific objections against nuclear energy. (author)

    2013-01-01

    Background Online mental health resources have been proposed as an innovative means of overcoming barriers to accessing rural mental health services. However, clinicians tend to express lower satisfaction with online mental health resources than do clients. Objective To understand rural clinicians’ attitudes towards the acceptability of online mental health resources as a treatment option in the rural context. Methods In-depth interviews were conducted with 21 rural clinicians (general practitioners, psychologists, psychiatrists, and clinical social workers). Interviews were supplemented with rural-specific vignettes, which described clinical scenarios in which referral to online mental health resources might be considered. Symbolic interactionism was used as the theoretical framework for the study, and interview transcripts were thematically analyzed using a constant comparative method. Results Clinicians were optimistic about the use of online mental health resources into the future, showing a preference for integration alongside existing services, and use as an adjunct rather than an alternative to traditional approaches. Key themes identified included perceptions of resources, clinician factors, client factors, and the rural and remote context. Clinicians favored resources that were user-friendly and could be integrated into their clinical practice. Barriers to use included a lack of time to explore resources, difficulty accessing training in the rural environment, and concerns about the lack of feedback from clients. Social pressure exerted within professional clinical networks contributed to a cautious approach to referring clients to online resources. Conclusions Successful implementation of online mental health resources in the rural context requires attention to clinician perceptions of acceptability. Promotion of online mental health resources to rural clinicians should include information about resource effectiveness, enable integration with existing

    1979-01-01

    Public response to risks of nuclear energy is investigated. A quantitative description of the attitudes, perceptions, and expectations of some members of the antinuclear public is given. Sample studies of the public at large were not made; most of the data in the paper comes from survey made at the University of Oregon and another with members of the Eugene, Oregon, League of Women Voters. Perceived risks and benefits, relative to other activities; risk characteristics; the reasons nuclear power is thought to be so dangerous; why death from nuclear power is thought to be so much worse than death from other causes; fatality estimates and disaster multipliers for 30 activities and technologies (alcoholic beverages, bicycles, commercial aviation, contraceptives, electric power, nuclear power, vaccinations, x-rays); fatality estimates associated with maximum credible disasters from commerical aviation and nuclear power are some of the areas covered in the surveys. The authors' view is that educational attempts designed to reduce the perception gap are probably doomed to failure, based on technical and psychological aspects of the problem. After discussing these issues, pathways toward acceptance of nuclear and nonnuclear energy systems are examined

    Public acceptance has become an important factor in nuclear power program particularly after Chernobyl accident and recent rapid democratization in Korea. Methods reflection public opinions in order to improve public acceptance are firstly to understand what the public think about nuclear power plant and secondly to find out the public preference values for its policies. For this purpose, simplified multi-attribute utility(MAU) model was applied to analyze the public perception for five power production system. And the conjoint analysis was applied to find out he quantitative values of public preferences for twelve policy alternatives to improve the safety and support communities surrounding nuclear power plants in Korea. To implement these perception and preference analyses, mail survey was conducted to the qualified sample who had the experience of visiting nuclear power plant. Diagnosis of their perception pattern for five power production systems was made by the simplified MAU model. Estimation of the quantitative preference values for potential policy alternatives was made by the conjoint measurement technique, which made it possible to forecast the effectiveness of each option. The results from the qualified sample and the methods used in this study would be helpful to set up new policy of nuclear power plant. 4 figs., 7 tabs., 18 refs. (Author)

  6. Perceptions and Acceptance of Desalinated Seawater for Irrigation: A Case Study in the Níjar District (Southeast Spain

    Directory of Open Access Journals (Sweden)

    José A. Aznar-Sánchez

    2017-06-01

    Full Text Available In the context of increasing demand for irrigation water—but, at the same time, with the constraints in the supply from traditional resources—desalinated seawater has been recognized as one of the alternative sources of water to increase the supply for agricultural irrigation. However, its use among farmers has not yet started to expand. Policy makers need to understand what is causing the low acceptance levels of farmers, and how their attitudes could be improved. This is the first study that has conducted an analysis of farmers’ perceptions and acceptance of the use of desalinated seawater for irrigation. The study is based on collected data from a survey completed by farmers in southeastern Spain who do not use desalinated seawater. The main results indicate that desalinated seawater as a water supply source has the lowest acceptance level for farmers. Barriers for its use are price, the need for additional fertilization, and the perception that it would negatively affect the yield and crop quality. The farmers’ general level of knowledge about the impact of using desalinated seawater in agriculture is extremely low. Furthermore, farmers consider it a priority that their startup investment should be subsidized and that water prices should be reduced. Based on the study findings, this paper makes recommendations for the decision-making process in order to improve farmers’ acceptance levels.

    Torri, Luisa; Salini, Silvia

    2016-12-01

    In a food exhibition where several producers of the same product category are present at the same time, consumers usually have the opportunity to taste several free samples of the same product type, thus they can experience and compare the sensory characteristics of each and evaluate their liking for each sample tasted. This study assessed the potential of an itinerant sensory data collection in understanding the consumers' perception and acceptance of cheese during a multiple tasting experience at a food exhibition. Subjects tasted seven samples of Parmigiano Reggiano cheese aged for different times (24 and 36months) at seven producer stands and recorded their evaluations using tablets, on which an application specifically developed for this study was installed. This evaluation situation was defined as "pseudo-natural," in opposition to the "natural" and the "naturalistic" settings. The itinerant sensory session comprised a liking test, a rate-all-that-apply (RATA) test using a just about right (JAR) scale, a food pairing test, and a questionnaire. Consumers significantly (panalysis, and decision tree models in investigating the relationships between liking and the RATA data, provided results revealing that the attributes elasticity, sweetness, humidity, fresh fruit, and butter were the main drivers of liking. Whereas, the attributes sourness, bitterness, and hardness were the main drivers of dislike. Therefore, even though no significant differences in terms of liking were observed among the tested cheeses, consumers preferred the attributes more frequently perceived in the least aged products. In conclusion, the presented itinerant sensory approach had provided meaningful information to understand the consumers' cheese perception and acceptability. In the future, it could advantageously be applied for studying food perception in other situations in which subjects naturally choose or consume several products while freely moving from one to another (e.g. self

    Full Text Available The flipped classroom instructional model has emerged as an alternative to conventional lecture-based teaching that has dominated higher education for decades. In 2013, a cohort of graduate-level public health students participated in a flipped environmental and occupational health course. We present the design, implementation, and evaluation of this course. Using data collected from a post-course survey, focus group sessions, and classroom observation, we examine student perceptions of the flipped classroom instructional model and synthesize lessons learned from flipping the classroom more broadly. Post-course survey data indicate that students had generally positive perceptions towards the flipped classroom instructional model. Four major themes emerged from the focus group data in relation to perceptions of the flipped classroom: knowledge application, content delivery, innovation, and connecting the online and in-class components. These results are promising and suggest that this approach warrants further consideration and research. Le modèle pédagogique de la classe inversée a émergé comme solution de rechange à l’enseignement traditionnel par cours magistraux qui a dominé l’éducation supérieure pendant des décennies. En 2013, une cohorte d’étudiants en santé publique aux cycles supérieurs a participé à un cours inversé sur la santé environnementale et professionnelle. Nous présentons la conception, la mise en œuvre et l’évaluation de ce cours. À l’aide de données recueillies par l’entremise d’un sondage après le cours, lors de séances de discussion en groupe et d’observation en classe, nous examinons les perceptions qu’ont les étudiants du modèle pédagogique de la classe inversée et résumons les leçons tirées qui sont pertinentes pour les cours inversés en général. Les données du sondage réalisé après le cours indiquent que les étudiants avaient des perceptions pour la plupart

    New drug and medical device introduction in Japan usually lags behind that in the West. Many reports indicate that in Japan, the associated risks are considered greater than the benefits recognized in other countries. This study aimed to compare the relationship between risk-benefit perception and acceptance of medical technologies in 3 leading markets. A tripartite cross-sectional survey of the general public was used. In total, 3345 adults in the United Kingdom, the United States, and Japan participated, and sexes and age groups were equally represented. Questions about the perception of risk, benefit, and acceptance of medical and other scientific technologies, and trust of medical product providers or regulatory authorities were included. Five-step Likert coding for risk/benefit/acceptance of 4 medical items (x-rays, antibiotics, vaccines, and cardiac pacemakers) and 6 general items (such as automobiles and airplanes) were collected. Relationships between benefit perception and acceptance were linear for 4 medical technologies. The relationship had a similar slope but was shifted downward in Japan compared with the UK and US ( P medical technologies, benefits of medical technologies, trust in doctors, and trust in the Department of Health. The UK and US attributes were clustered with positive responses such as "useful," "acceptable," and "trustworthy," whereas Japan was clustered with intermediate to negative responses such as "neither" and "untrustworthy." Acceptance of medical technologies was low in Japan because of significant differences in trust for doctors and authorities compared with that in the UK and US. This is a possible basis for delays of 24 to 60 months for medical product approval in Japan.

Generic medicines provide the same therapeutic outcomes but at a much cheaper cost, so are promoted in many countries to contain pharmaceutical expenditure and sustain the health care system. Thus, the perspective of patients and medicine consumers as end users of these medicines is an important factor to enhance the use and utilization of generic medicines. The objective of this paper is to review patients’ and consumers’ knowledge, perceptions, acceptance, and views of generic medicines in the current literature. Methods: An extensive literature search was performed in several databases, namely Scopus, PubMed, ISI Web of Knowledge, Proquest, and the Wiley online library, to identify relevant studies published in the English literature for the period 1990–2013. Results: A total of 53 studies were included in the review, comprising 24 studies from Europe, ten from North America, six from Asia, five from Australia and New Zealand, five from the Middle East, one from Africa, one from Latin America, and one from the Caribbean region. A large body of literature has reported misconceptions and negative perceptions about generic medicines on the part of patients and medicine consumers.

    Malaysian government’s aim to include nuclear energy for electricity generation has triggered various reactions from all especially the public. The objective of this study is to have a better understanding on the knowledge, sources of information of nuclear power and sources of energy chosen by Malaysian in 20 years’ time. Besides that, we want to examine the level of acceptance and perception of Malaysian towards nuclear energy and we want to identify the correlation between public perceptions with the acceptance towards nuclear power in Malaysia, and also to study the differences between perception and acceptance of nuclear power with gender and educational level. For this research methodology, the research questions are given orally or through paper-pencil and also social networking site such as Facebook or through electronic media application such as WhatsApp and Google docs. The data were analysed using a SPSS version 22.0 (Statistical Package for the Social Sciences). Results showed that more than 50% of the respondents have the knowledge of nuclear energy. A part of from that, only 39 % are confident government can afford to build NPP in Malaysia and 41 % disagree nuclear energy is the best option for future energy. From analysis using SPSS 22 we estimate negative perception will give a negative acceptance in term of support towards the use of nuclear energy in power generation in Malaysia. There are also slight correlation that the higher the level of education of Malaysian, the more negative the perception of Malaysian in accepting nuclear energy as source of power in Malaysia. Therefore in shaping a positive acceptance of NPP in Malaysia, the authorities need to educate the people with the knowledge of nuclear in order to overcome the negative perception towards nuclear power.

    This report presents the results of a research study with lay peoples perception regarding hydrogen technologies. This study aims to explore how to shape public perception and acceptance of hydrogen technologies in Spain and permits the identification of issues that may facilitate or interfere with its development and implementation. The results showed the existence of a large and widespread lack of knowledge towards hydrogen technologies. Hydrogen is perceived as a clean energy technology and nearby to renewable energies. However, it is still not seen as an energetic option. The main drawbacks perceived by lay people have been the lack of profitability, the slow evolution of the technology and the absence of technological developments. Furthermore, hydrogen cost and safety issues appear to play an important role in public acceptance of these technologies. (Author) 35 refs.

    Characteristic off-flavours may occur in uncastrated male pigs depending on the accumulation of androstenone and skatole. Feasible processing of strongly tainted carcasses is challenging but gains in importance due to the European ban on piglet castration in 2018. This paper investigates consumers' acceptability of two sausage types: (a) emulsion-type (BOILED) and (b) smoked raw-fermented (FERM). Liking (9 point scales) and flavour perception (check-all-that-apply with both, typical and negatively connoted sensory terms) were evaluated by 120 consumers (within-subject design). Proportion of tainted boar meat (0, 50, 100%) affected overall liking of BOILED, F (2, 238)=23.22, P<.001, but not of FERM sausages, F (2, 238)=0.89, P=.414. Consumers described the flavour of BOILED-100 as strong and sweaty. In conclusion, FERM products seem promising for processing of tainted carcasses whereas formulations must be optimized for BOILED in order to eliminate perceptible off-flavours. Boar taint rejection thresholds may be higher for processed than those suggested for unprocessed meat cuts. Copyright © 2016 Elsevier Ltd. All rights reserved.

  9. Local perceptions of cholera and anticipated vaccine acceptance in Katanga province, Democratic Republic of Congo

    Science.gov (United States)

    2013-01-01

    Background In regions where access to clean water and the provision of a sanitary infrastructure has not been sustainable, cholera continues to pose an important public health burden. Although oral cholera vaccines (OCV) are effective means to complement classical cholera control efforts, still relatively little is known about their acceptability in targeted communities. Clarification of vaccine acceptability prior to the introduction of a new vaccine provides important information for future policy and planning. Methods In a cross-sectional study in Katanga province, Democratic Republic of Congo (DRC), local perceptions of cholera and anticipated acceptance of an OCV were investigated. A random sample of 360 unaffected adults from a rural town and a remote fishing island was interviewed in 2010. In-depth interviews with a purposive sample of key informants and focus-group discussions provided contextual information. Socio-cultural determinants of anticipated OCV acceptance were assessed with logistic regression. Results Most respondents perceived contaminated water (63%) and food (61%) as main causes of cholera. Vaccines (28%), health education (18%) and the provision of clean water (15%) were considered the most effective measures of cholera control. Anticipated vaccine acceptance reached 97% if an OCV would be provided for free. Cholera-specific knowledge of hygiene and self-help in form of praying for healing were positively associated with anticipated OCV acceptance if costs of USD 5 were assumed. Conversely, respondents who feared negative social implications of cholera were less likely to anticipate acceptance of OCVs. These fears were especially prominent among respondents who generated their income through fishing. With an increase of assumed costs to USD 10.5, fear of financial constraints was negatively associated with anticipated vaccine acceptance as well. Conclusions Results suggest a high motivation to use an OCV as long as it seems affordable. The

    1989-09-01

    Full text: While Protective Action Guides or PAGs have been a part of the lexicon of the radiation protection field for several decades, the concept of accepting higher levels of risk under certain situations has not received adequate scrutiny by the general public, the media or elected officials. Consequently there is a question as to how implementation of PAGs would be perceived by the above groups in the event that such implementation became necessary. A personal case in point involves the response of an executive in the food industry. When the concept of selling a food product meeting the PAGs was explained his response was, 'we won't sell a contaminated product, we would dump the unprocessed raw food. Our industry image is that of a natural unadulterated food'. While this may be an isolated view, there is a need to determine what is the perception and consequently what would be the response if PAGs were implemented today. If the response was negative by anyone of the three groups listed previously, then there is an obvious need for a program to assure receptiveness by those concerned. However, this may face formidable obstacles. This is because the terms radiation and radioactive have gained generally negative word associations, e.g. 'deadly' radiation and radioactive 'desert'. The former term was recently heard in a taped presentation at a Museum of Natural History on a completely unrelated subject. The latter term was part of a recent article heading in the Wall Street Journal. Incidentally the article was discussing television. Thus beyond the scientific issues of setting PAGs and the administrative and procedural issues of implementing PAGs there is the issue of society's understanding and acceptance of PAGs. Particularly, how can such understanding and acceptance be achieved in a situation which is associated with an actual or perceived radiation emergency? These are not questions that radiation or agricultural scientists can answer alone. These are

    Female smoking prevalence in China is very low but may rise with increased tobacco marketing towards women and changing norms. However, little is known about current perceptions of women smoking in China. This study sought to examine smokers' and non-smokers' perceived acceptability of female smoking and how it changed over time in China. Data come from Waves 1 to 3 (2006-2009) of the International Tobacco Control China Survey, a face-to-face cohort survey of approximately 800 adult smokers and 200 non-smokers in each of seven cities in mainland China. At Wave 3 (2009), about 38% of smokers and 9% of non-smokers agreed that female smoking is acceptable with women being almost twice as likely to do so as men (67% vs 36% and 11% vs 6%, respectively). In addition to women, smokers who were younger and had more positive perceptions of smoking in general were more likely to say that female smoking is acceptable. This perception significantly increased from Wave 1 (2006) to Wave 3 (2009), as did the perception that smoking is a sign of sophistication, but other general perceptions of smoking did not significantly change between 2006 and 2009. Norms against female smoking appear to remain strong in China, but female smoking may be becoming more acceptable. It is important to monitor these perceptions to prevent a rise in female smoking prevalence along with an increase in tobacco-related death and disease among women in China.

    Human papillomavirus (HPV) vaccination has been perceived in diverse ways some of which encourage its uptake while others could potentially deter its acceptability. This study explored community member's perceptions about HPV vaccination in Ibanda district and the implications of the perceptions for acceptability of HPV vaccination. The study was conducted following initial vaccination of adolescent schoolgirls in the district between 2008 and 2011. This qualitative study employed focus group discussions (FGDs) and key informant interviews (KIIs). FGDs were conducted with schoolgirls and parents/guardians and KIIs were conducted with school teachers, health workers and community leaders. Transcripts from the FGDs and KIIs were coded and analyzed thematically using ATLAS.ti (v. 6). The HPV vaccination was understood to safely prevent cervical cancer, which was perceived to be a severe incurable disease. Vaccinations were perceived as protection against diseases like measles and polio that were known to kill children. These were major motivations for girls' and parents' acceptance of HPV vaccination. Parents' increased awareness that HPV is sexually transmitted encouraged their support for vaccination of their adolescent daughters against HPV. There were reports however of some initial fears and misconceptions about HPV vaccination especially during its introduction. These initially discouraged some parents and girls but over the years with no major side effects reported, girls reported that they were willing to recommend the vaccination to others and parents also reported their willingness to get their daughters vaccinated without fear. Health workers and teachers interviewed however explained that, some concerns stilled lingered in the communities. The perceived benefits and safety of HPV vaccination enhanced girls' and parents' acceptability of HPV vaccination. The initial rumors, fears and concerns about HPV vaccination that reportedly discouraged some girls and

La méthodologie présente le design de la recherche, les instruments utilisés pour les entretiens et pour animer le groupe de discussion. Les résultats montrent que pour une enseignante qui avait déjà adopté la pédagogie sous-jacente au renouveau pédagogique Québécois, le portfolio électronique était une expérience fort utile. Toutefois, pour les deux autres enseignants, l’implantation du portfolio électronique était beaucoup trop exigeante. Finalement, nous discutons des implications des résultats, autant au point de vue de l’expérience d’implantation des portfolios électroniques que du point de vue de la contribution méthodologique. This article presents an analysis of the perceptions of teachers, which took place in 2010 at the end of an experiment implementing an e-portfolio that facilitates student self-regulation of learning. The article is based on the current Quebec educational context. It presents a review of literature on technology skills, e-portfolios and the self-regulation of learning. The methodology describes the research design, the tools used in the individual interviews and in the group discussion. The results indicate that the e-portfolio was a valuable experience for a teacher who had already adopted the pedagogy underlying the education reform in Quebec.

    Perceptions of risk from radiation have been studied systematically for about 20 years. This paper summarises the key findings and conclusions from this research with regard to the nature of risk perceptions, the impacts of these perceptions, and the need for communication about radiological hazards. Perhaps the most important generalisation from research in this area is that there is no uniform or consistent perception of radiation risks. Public perception and acceptance is determined by the context in which the radiation is used -and the very different reactions to different uses provide insight into the nature of perception and the determinants of acceptable risk.

    Full Text Available Tuberculosis (TB is global health concern and a leading infectious cause of mortality. Reversing TB incidence and disease-related mortality is a major global health priority. Infectious disease mortality is directly linked to failure to adhere to treatments. Using technology to send reminders by short message services have been shown to improve treatment adherence. However, few studies have examined tuberculosis patient perceptions and attitudes towards using SMS technology to increase treatment adherence. In this study, we sought to investigate perceptions related to feasibility and acceptability of using text messaging to improve treatment adherence among adults who were receiving treatment for TB in Callao, Peru.We conducted focus group qualitative interviews with current TB positive and non-contagious participants to understand the attitudes, perceptions, and feasibility of using short message service (SMS reminders to improve TB treatment adherence. Subjects receiving care through the National TB Program were recruited through public health centers in Ventanilla, Callao, Peru. In four focus groups, we interviewed 16 patients. All interviews were recorded and transcribed verbatim. Thematic network analysis and codebook techniques were used to analyze data.Three major themes emerged from the data: limits on health literacy and information posed challenges to successful TB treatment adherence, treatment motivation at times facilitated adherence to TB treatment, and acceptability of SMS including positive perceptions of SMS to improve TB treatment adherence. The majority of patients shared considerations about how to effectively and confidentially administer an SMS intervention with TB positive participants.The overall perceptions of the use of SMS were positive and indicated that SMS technology may be an efficient way to transmit motivational texts on treatment, health education information, and simple reminders to increase treatment adherence

    Full Text Available Student test anxiety (TA is a far-reaching concern in many post-secondary institutions as it can have a negative impact on student performance and retention. Educator perceptions of TA may influence the incidence of TA as well as treatment success. As such, we surveyed educators at a medium-sized Canadian university about their perceptions and experiences with TA. In total, 90% of surveyed educators (n=50 were willing to accommodate students with TA, and 69% of educators were aware of TA support services on campus, whereas only 40% could identify symptoms of TA. Two principal components were extracted from survey responses: the importance of TA on campus, and the importance of institutional commitment to managing TA. Perceived importance of TA varied by educator age and sex, with female and older educators perceiving TA as a more serious condition than male and younger educators. Educators that were aware of TA services had a more positive view of institutional commitment to TA. In addition, 42% of educators felt limited in their ability to assist students with TA, and only 40% believed their classes were structured in such a way as to minimize or address TA. Providing information to educators about the symptoms and treatability of TA, as well as available support services is recommended. L’anxiété des étudiants face aux examens est une préoccupation qui a des implications importantes dans de nombreux établissements d’enseignement post-secondaire car elle peut avoir des effets négatifs sur les résultats des étudiants et sur leur rétention. Les perceptions des éducateurs concernant l’anxiété face aux examens risquent d’influencer l’incidence de l’anxiété ainsi que la réussite du traitement. C’est pourquoi nous avons fait un sondage auprès d’éducateurs dans une université canadienne de taille moyenne à propos de leurs perceptions et de leurs expériences concernant l’anxiété face aux examens.

  9. Acceptance of new sanitation: The role of end-users' pro-environmental personal norms and risk and benefit perceptions.

    Current sanitation systems are inherently limited in their ability to address the new challenges for (waste)water management that arise from the rising demand to restore resource cycles. These challenges include removal of micropollutants, water (re)use, and nutrient recovery. New opportunities to address these challenges arise from new sanitation, a system innovation that combines elements of source separation, local treatment and reuse, and less use of water. New sanitation is applied, but not yet widespread, in several residential areas in Europe. Implementation is hindered by the lack of insight into the general public's willingness to engage in new sanitation, and the resulting uncertainty about this among decision makers and other stakeholders in wastewater management. Using value-belief-norm theory as a conceptual lens, this paper addresses the individual motivations (pro-environmental personal norms) and personal drivers (benefits) and barriers (risks) for acceptance of new sanitation by the Dutch general public. The results of an online survey (N = 338) indicated that both pro-environmental personal norms and risk and benefit perceptions predict consumers' willingness to accept new sanitation. More specifically, they showed that consumer acceptance is driven by perceived risks relating to the housing market and the need to change behavior, but also by environmental benefits. Overall, new sanitation was favorably evaluated by respondents: 64% indicated that they would likely use new sanitation if they were owner-occupiers. The results of this explorative study are discussed in light of the development of novel sanitation systems that are sensitive to perceptions of end-users and other key stakeholders.

    Although there are current efforts to integrate herbal medicine (HM) into mainstream healthcare in Ghana, there is paucity of empirical evidence on the acceptability and concurrent use of HM, in the formal health facilities in Ghana. This study sought to determine client perception, disclosure and acceptability of integrating herbal medicine in mainstream healthcare in Kumasi, Ghana. A cross-sectional study was conducted from May to August, 2015. Five hundred patients presenting at the outpatient departments of Kumasi South, Suntreso and Tafo Government Hospitals in Kumasi were randomly selected. Interviews were conducted with the use of structured questionnaires. A logistic regression analysis, using backward selection, was conducted to determine the influence of socio-demographic and facility related factors on the odds of using HM at the facility. All statistical tests were two-sided and considered significant at a p-value of herbal medicines. Respondents who rated themselves wealthy had increased odds of using herbal medicines at the health facility as compared to those who rated themselves poor (OR = 4.9; 95%CI = 1.6-15.3). This study shows that integration of herbal medicine is feasible and herbal medicines may be generally accepted as a formal source of healthcare in Ghana. The results of this study might serve as a basis for improvement and upscale of the herbal medicine integration programme in Ghana.

    Full Text Available Les terres agricoles africaines sont convoitées par de nombreux investisseurs étrangers, ce qui se matérialise par une accélération des transactions portant sur des concessions foncières à grande échelle. Ces investissements répondent à des enjeux très divers et font l’objet de contrats rudimentaires, dont les clauses exactes sont souvent méconnues. Ce phénomène très médiatisé est extrêmement controversé et suscite de virulentes critiques, alors que les analyses scientifiques sur le sujet sont encore très rares.

    Objective. Direct electrical stimulation (DES) is a clinical gold standard for human brain mapping and readily evokes conscious percepts, yet the neurophysiological changes underlying these percepts are not well understood. Approach. To determine the neural correlates of DES, we stimulated the somatosensory cortex of ten human participants at frequency-amplitude combinations that both elicited and failed to elicit conscious percepts, meanwhile recording neural activity directly surrounding the stimulation site. We then compared the neural activity of perceived trials to that of non-perceived trials. Main results. We found that stimulation evokes distributed high gamma activity, which correlates with conscious perception better than stimulation parameters themselves. Significance. Our findings suggest that high gamma activity is a reliable biomarker for perception evoked by both natural and electrical stimuli.

  14. Issues affecting the acceptance of hydrogen fuel

    Schulte, I.; Hart, D.; Vorst, R. van der

    2004-01-01

    While the topic of hydrogen as an alternative vehicle fuel is gaining increasing attention internationally, one significant aspect of its introduction has been given less attention than others: the public acceptance of such a new technology and fuel. After reviewing the existing literature on acceptance, risk perception and customer satisfaction, this paper describes the development of a model that illustrates important aspects in influencing a person's attitude towards a new product. 'Values', 'wants' and 'perception' are the three components found to influence acceptance, they themselves are affected by 'social background' and 'experience'. Suggestions are then given on how to use marketing methods, education projects and product exposure in order to maximise the likelihood of a successful introduction of hydrogen as an alternative fuel.

  2. Perceptions of industrial and nuclear risks. Stakes, negotiations and social development of levels of risk acceptance

    International Nuclear Information System (INIS)

    Bernier, S.Ch.

    2007-11-01

    In this thesis we will question the perceptions of industrial risks in the occidental world at the beginning of the 21. century. For this purpose we will try to understand how concepts such as sustainable development, precautionary principle, liability, or even zero-risk bias have progressively developed around a thought model based on the scientific rationality. This model is now undermined by its incapacity to fully address the issues it raises and completely avoid the potential risks. However, despite consistent weaknesses, it remains a reference value moulded by past accidents which have led to the making of laws aiming mainly at defining liability and protecting those who are held liable. Thus, public information becomes a requirement for democracy and the protection of this thought model. In this context, the protagonists at stake are security-conscious, economical and political lobbies that constantly redefine the limits of risk acceptance. We come to the realization that our lifestyle and value system remain unchallenged even though undergoing a crisis. The specificity of this research lies into the importance we give to the local approach, dealing with registered Seveso sites and nuclear plants located in Indre et Loire. We have polled five categories of respondents through interviews or questionnaires in order to understand their opinion regarding situations involving technological risks. The result of this survey helps us understand and set the levels of risk acceptance that they define with regard to the industrial risks and show the complexity of a situation involving political stakes, environmental pressures, a profit-driven economy and security constraints, in a vague and complex context. This work gives us a contrasted picture of today's perceptions of risks. (author)

    Growing need of energy in global scale has resulted in increasing number of research and development of renewable energy technologies. Turkey, being very rich in the renewable energy resources, has recently paid special attention to accelerate utilization of these resources to reduce the carbon based energy cost. Among these, Geothermal Energy resources in the country, mainly utilized in district heating and balneological applications, has been shifted toward harvesting electric energy in the shed of recent incentives. While these developments are happening at the policy level, the knowledge and the perception of the public is important to shape the future policies and acceptance of such resources in daily life. In light of these developments, the aim of this study is to identify and analyze the public awareness and acceptance mechanisms for the successful deployment of future and ongoing geothermal investments in Çanakkale region of the Biga Peninsula using geological, social and economic constraints in a well-defined questionnaire. The study employed a mixed method to explore the public perception. Mixed method studies involve qualitative and quantitative techniques and intends to explore an issue in-depth. Thus a sequential explanatory design was used to gather the public's perception. Exploratory design involves a qualitative study followed by a design of a quantitative survey and analysis. The researchers, firs, interviewed 24 college students about their knowledge and perceptions of geothermal resources using a semi-structured interview protocol. The protocol comprised of 8 open ended questions. With the help of the literature and the qualitative survey results, an item database with 51 questions were constructed. The initial survey and the items then were sent to 5 experts. Following the expert review, the survey was given its final form and the item numbers were dropped to 34. Then this survey was applied to a group of 100 college students. The survey also

    It is well known in socio-economic studies, that the success of an innovation process depends not only on the technological innovation itself or the state of the economic and institutional environment, but also on the public acceptance of the innovation. Public acceptance can be an obstacle for the development and introduction of a new and innovative idea as the example of genetic engineering in agriculture shows. In respect to hydrogen technology this means, that the compilation and communication of scientific risk assessments are not sufficient to generate or enhance public acceptance. Moreover, psychological, social and cultural aspects of risk perception have to be considered when introducing new technologies. This paper focuses on trust as a central parameter of risk perception and the public acceptance of new technologies. (orig.)

    This study was undertaken to understand how consumers in the United States perceive umami-rich products, specifically low sodium chicken noodle soup. Results suggest that the addition of monosodium l-glutamate (MSG) at a concentration of 0.1% to 0.5%, alone or in synergy with 5'-ribonucleotides of inosine monophosphate (IMP) at 0.1% not only increases consumer acceptance but also positively impacts other aspects of consumer perception. Regardless of concentration of MSG and IMP, samples enhanced in umami compounds were perceived as more savory, flavorful, and less bland while providing a more homemade, fresh, and healthy wholesome taste than a control sample. From a functional and emotional benefit standpoint, when consuming umami-rich samples, consumers reported feeling significantly higher general satisfaction (they felt more content, relaxed, satisfied, less disappointed, dissatisfied…) and heightened positive emotions (happy, excited, indulgent…) than under the control condition. The feeling of being healthy while consuming the dish was not compromised. Last, when asked how they would feel if serving the soup sample to their family or friends, consumers projected feeling more positively under the umami-rich conditions (more happy, competent, loving, less dissatisfied or disappointed) compared to the control condition. © 2015 Institute of Food Technologists®

    The determinants of the public's nuclear power acceptance have received considerable attention as decisive factors regarding nuclear power policy. However, the contingency of the relative importance of different determinants has been less explored. Building on the literature of psychological distance between the individual and the object, the present study demonstrates that the relative effects of different types of perceived risks regarding nuclear power generation differ across acceptance targets. Using a sample of Korea, our results show that, regarding national acceptance of nuclear power generation, perceived risk from nuclear power plants exerts a stronger negative effect than that from radioactive waste management; however, the latter exerts a stronger negative effect than the former on local acceptance of a nuclear power plant. This finding provides implications for efficient public communication strategy to raise nuclear power acceptance

    BSAP-I optimisés à travers une caractérisation complète des propriétés mécaniques et de la durabilité a été réalisée. A la suite de cette étude, les résultats obtenus nous permettent de conclure que : (1) L'utilisation d'un BSAP-I avec un gros granulat de 5 - 14 mm, des rapports E/L = 0,37 et S/G = 0,52 et une teneur en air de 6 à 9% a été possible en conférant un équilibre optimal fluidité / stabilité à l'état frais, ainsi qu'un niveau de thixotropie adéquate au chantier permettant d'optimiser la conception du coffrage des piliers de pont et de conférer des qualités de surfaces très acceptables de ces infrastructures. (2) La méthode adaptée pour l'essai L-Box contenant 2 barres et une vibration de 5 secondes a permis de bien caractériser la capacité de remplissage d'un BSAP-I. (3) L'utilisation d'un plan factoriel 23 a permis d'obtenir des modèles statistiques fiables, capables de prédire les propriétés rhéologiques à l'état frais et les résistances en compression des BSAP-I avec des dosages en liant entre 370 et 420 kg/m3, des rapports E/L entre 0,34 et 0,40 et S/G entre 0,47 et 0,53. (4) Des mesures de vitesse d'écoulement T40 d'un BSAP-I sont très semblables à celles d'un BAP. En plus, des valeurs T40 montrent une bonne corrélation linéaire avec celles de T400 mesurés dans la boîte L-Box. (5) À la frontière du BAP et du BCV, une bande rhéologique possédant un τ0 entre 30 et 320 Pa et un η entre 10 et 140 Pa.s a été trouvée pour la conception optimale des BSAP-I. (6) Les BSAP-I optimisés ont également conféré une très bonne performance à l'état frais, en permettant maintenir un bon équilibre entre la rhéologie et la stabilité dans le temps, lorsqu'on utilise une énergie de vibration minimale pour amorcer son écoulement. (7) À l'état durci Les BSAP-I ont conféré une bonne performance présentant des résistances mécaniques élevées et des niveaux négligeables de pénétration aux ions chlores

    Although barriers to shared decision making in intensive care units are well documented, there are currently no easily scaled interventions to overcome these problems. We sought to assess stakeholders' perceptions of the acceptability, usefulness, and design suggestions for a tablet-based tool to support communication and shared decision making in ICUs. We conducted in-depth semi-structured interviews with 58 key stakeholders (30 surrogates and 28 ICU care providers). Interviews explored stakeholders' perceptions about the acceptability of a tablet-based tool to support communication and shared decision making, including the usefulness of modules focused on orienting families to the ICU, educating them about the surrogate's role, completing a question prompt list, eliciting patient values, educating about treatment options, eliciting perceptions about prognosis, and providing psychosocial support resources. The interviewer also elicited stakeholders' design suggestions for such a tool. We used constant comparative methods to identify key themes that arose during the interviews. Overall, 95% (55/58) of participants perceived the proposed tool to be acceptable, with 98% (57/58) of interviewees finding six or more of the seven content domains acceptable. Stakeholders identified several potential benefits of the tool including that it would help families prepare for the surrogate role and for family meetings as well as give surrogates time and a framework to think about the patient's values and treatment options. Key design suggestions included: conceptualize the tool as a supplement to rather than a substitute for surrogate-clinician communication; make the tool flexible with respect to how, where, and when surrogates can access the tool; incorporate interactive exercises; use video and narration to minimize the cognitive load of the intervention; and build an extremely simple user interface to maximize usefulness for individuals with low computer literacy.

    Economic growth in the past decades has resulted in change in consumption pattern and emergence of tech-savvy generation with unprecedented increase in the usage of social network technology. In this paper, the technology acceptance value gap adapted from the technology acceptance model has been applied as a tool supporting social network technology usage and subsequent promotion of sustainable consumption. The data generated through the use of structured questionnaires have been analyzed using structural equation modeling. The validity of the model and path estimates signifies the robustness of Technology Acceptance value gap in adjudicating the efficiency of social network technology usage in augmentation of sustainable consumption and awareness. The results indicate that subjective norm gap, ease-of-operation gap, and quality of green information gap have the most adversarial impact on social network technology usage. Eventually social networking technology usage has been identified as a significant antecedent of sustainable consumption.

  19. A Mutual Acculturation Model of Multicultural Campus Climate and Acceptance of Diversity

    Simmons, Samantha; Wittig, Michele A.; Grant, Sheila K.

    2010-01-01

    This study examines the relationship between college students’ perceptions of their campus’ multicultural climate and their acceptance of racial/ethnic diversity. A two-mediator model, based on acculturation principles, was successfully fit to survey data from 434 college students of diverse racial/ethnic heritage. Results showed that valuing positive interactions with members of ethnocultural groups other than one’s own is a positive mediator and strength of ethnocultural identity is a (much less important) negative mediator of the relationship between student perceptions of multicultural campus programming and personal acceptance of diverse racial/ethnic groups. Furthermore, each mediator independently contributed to the prediction of such acceptance. Overall, the model accounts for about 25% of the variance in acceptance of diversity and was a better fit to the data than a reverse path model. Follow-up analyses, separately by ethnic group, showed that perceptions of campus programming predicted acceptance of diversity for the White subsample, but not for the Latino subsample. Nevertheless, the two acculturation-related constructs were important for both groups, with the model accounting for 28% and 24% of their respective variances in acceptance of diversity. Practical implications are drawn. PMID:21058809

  1. Acceptably aware during general anaesthesia: 'dysanaesthesia'--the uncoupling of perception from sensory inputs.

    Science.gov (United States)

    Pandit, Jaideep J

    2014-07-01

    This review makes the case for 'dysanaesthesia', a term encompassing states of mind that can arise in the course of anaesthesia during surgery, characterised by an uncoupling of sensation and perceptual experience. This is reflected in a macroscopic, functional model of anaesthetically-relevant consciousness. Patients in this state can be aware of events but in a neutral way, not in pain, sometimes personally dissociated from the experiences. This makes events associated with surgery peripheral to their whole experience, such that recall is less likely and if it exists, makes any spontaneous report of awareness unlikely. This state of perception-sensation uncoupling is therefore broadly acceptable (a minimum requirement for acceptable anaesthesia) but since it is likely a dose-related phenomenon, may also represent a precursor for awareness with adverse recall. This hypothesis uniquely explains the often inconsistent responses seen during the experimental paradigm of the 'isolated forearm technique', wherein apparently anaesthetised patients exhibit a positive motor response to verbal command, but no spontaneous movement to surgery. The hypothesis can also explain the relatively high incidence of positive response to relatively direct questions for recall (e.g., using the Brice questionnaire; ∼1:500; the vast majority of these being neutral reports) versus the very low incidence of spontaneous reports of awareness (∼1:15,000; a higher proportion of these being adverse recollections). The hypothesis is consistent with relevant notions from philosophical discussions of consciousness, and neuroscientific evidence. Dysanaesthesia has important implications for research and also for the development of appropriate monitoring. Copyright © 2014 Elsevier Inc. All rights reserved.

    Nowdays, due to the increasing importance of quality care, organizations focuse on the improving provision, management and distribution of health. On one hand, incremental costs of the new technologies and on the other hand, increased knowledge of health care recipients and their expectations for high quality services have doubled the need to make changes in order to respond to resource constraints (financial, human, material). For this purpose, several technologies, such as barcode, have been used in hospitals to improve services and staff productivity; but various factors effect on the adoption of new technologies and despite good implementation of a technology and its benefits, sometimes personnel don't accept and don't use it. This is an applied descriptive cross-sectional study in which all the barcode users in health information management department of the three academic hospitals (Feiz, Al-Zahra, Ayatollah Kashani) affiliated to Isfahan University of Medical Sciences were surveyed by the barcode technology acceptance questionnaire, in six areas as following: barcode ease of learning, capabilities, perception of its usefulness and its ease of use, users attitudes towards its using, and users intention. The finding showed that barcode technology total acceptance was relatively desirable (%76.9); the most compliance with TAM model was related to the user perceptions about the ease of use of barcode technology and the least compliance was related to the ease of learning barcode technology (respectively %83.7 and %71.5). Ease of learning and barcode capability effect of usefulness and perceived ease of barcode technology. Users perceptions effect their attitudes toward greater use of technology and their attitudes have an effect on their intention to use the technology and finally, their intention makes actual use of the technology (acceptance). Therefore, considering the six elements related to technology implementation can be important in the barcode

    In this context, it is necessary to manage and develop an index that can measure the level of public acceptance by establishing the terms of social/cultural public acceptance of nuclear power in a practical manner and by identifying influential factors of public acceptance. Developing an index itself is not intended to increase the public acceptance of nuclear power. This study intends to contribute to determining energy policy acceptable to the public by estimating the level of potential social conflicts related to nuclear power policies with eligible evaluation criteria on social/cultural acceptance and by reducing relevant social costs. Key conclusions and proposal of this research are as follows. First, the influential factors of acceptance are reliability of nuclear safety, risk perception of nuclear power and beneficial perception of nuclear power. Among them, reliability of nuclear safety appears to have the most influence. In addition, benefit perception of nuclear power at the social level is significantly higher than that at the individual level. However, in relation to risk perception, a gap between experts and the public is found as nuclear industry premises that accident does not occur while the public premises that accident may occur.

    Drivers of liking (DOL) studies are useful for product development to formulate acceptable products; however, DOL alone are insufficient for understanding why a product is purchased and repurchased, which is ultimately the indication of a successful product. Ultimately sensory attributes drive product success (that is, repeat and continued purchase). However, ignoring the importance of extrinsic factors may neglect the vital product attributes responsible for the initial purchase, which may in turn, affect repeat purchase. The perception of sensory attributes assessed by DOL is mitigated by external perceptions of quality. If the sensory attributes do not deliver based upon the quality cues, the product will not be acceptable. Four key extrinsic factors that affect DOL are the perceived satiety, brand and labeling, price, and the emotional impact to decision making. In order to more thoroughly understand what the DOL for a product is, these 4 product cues should be considered in conjunction with sensory attribute perception to gain a holistic understanding of product acceptance. © 2015 Institute of Food Technologists®

    Social acceptance is a condition in performing energy projects. This notion is however complex: just like 'build', it is based on several factors and is changing. We would like to show that its construction requires that some time be spend at a stage often neglected, that of the formulation of the problem. So that the 'awareness' would be aimed not only to the public, but also to the decision makers and promoters, so that everyone has a good knowledge of the concerns of the others, and of their limits. To this end, the 'participation' could take several forms, complementary to the 'public' one generally accepted. [French] L'acceptabilite sociale est une condition de realisation de projets energetiques. Cette notion est toutefois complexe : comme 'construit', elle se fonde sur plusieurs facteurs et est evolutive. Nous voudrions montrer que sa construction exige qu'un temps soit consacre a une etape souvent negligee, celle de la formulation du probleme. Ainsi, la 'sensibilisation' serait destinee non seulement au grand public, mais aussi aux decideurs et promoteurs, afin que tous aient une bonne connaissance des preoccupations des uns et des autres, comme de leurs contraintes. A cette fin, la 'participation' pourrait prendre plusieurs formes, complementaires a celle 'publique' generalement adoptee.

    2017-01-01

    Global warming is a central threat for today's society caused by greenhouse gas emissions, mostly carbon dioxide emissions. Carbon dioxide capture and utilization (CCU) is a promising approach to reduce emissions and the use of expensive and limited fossil resources. Applying CCU, carbon dioxide (CO_2) can be incorporated as raw material during the manufacture of plastic products. While most of the studies address technical feasibilities, hardly any systematic research on public perception and acceptance of those specific products exists so far. This study empirically investigates the acceptance of CCU plastic products (mattress as example). First, interviews with experts and lay people revealed critical acceptance factors (CO_2 proportion, saving of fossil resources, disposal conditions, perceived health complaints). Their relative importance was detailed in two consecutive conjoint studies. Study 1 revealed disposal conditions and saving of fossil resources as essential for product selection, while the products’ CO_2 proportion was less important. In study 2, potential health complaints were integrated as well as individual levels of domain knowledge and risk perception, which significantly affected acceptance of CCU products. Recommendations concerning communication strategies for policy and industry were derived. - Highlights: • Study provides insights into the acceptance of specific CCU products. • Disposal conditions and savings of fossil resource are main drivers of acceptance. • Concerns about potential health effects act as major barrier especially for laypeople. • Perceived knowledge and risk perception affect CCU product acceptance. • Communication strategy recommendations for policy and industry are derived.

    After the Swiss government's decision to decommission its five nuclear power plants by 2035, energy production from wind, biomass, biogas and photovoltaic is expected to increase significantly. Due to its many aspects of a direct democracy, high levels of public acceptance are necessary if a substantial increase in new renewable energy power plants is to be achieved in Switzerland. A survey of 502 citizens living near 19 biogas plants was conducted as the basis for using structural equation modeling to measure the effects of perceived benefits, perceived costs, trust towards the plant operator, perceived smell, information received and participation options on citizens’ acceptance of “their” biogas plant. Results show that local acceptance towards existing biogas power plants is relatively high in Switzerland. Perceived benefits and costs as well as trust towards the plant operator are highly correlated and have a significant effect on local acceptance. While smell perception and information received had a significant effect on local acceptance as well, no such effect was found for participation options. Reasons for the non-impact of participation options on local acceptance are discussed, and pathways for future research are presented. - Highlights: • Acceptance of biogas plants by local residents in Switzerland is relatively high. • Local acceptance is highly affected by perceived outcomes and citizens’ trust. • Smell perception increases perceived costs and reduces perceived benefits and trust. • Information offers reduce perceived costs and increase trust and perceived benefits. • Participation offers do not have any effect on local acceptance

    User acceptance of information technology has been a significant area of research for more than two decades in the field of information technology. This study assessed the acceptance of information technology in the context of Health Information Management (HIM) by utilizing Technology Acceptance Model (TAM) which was modified and applied to assess user acceptance of health information technology as well as viability of TAM as a research construct in the context of HIM. This was a descriptive- analytical study in which a sample of 187 personnel from a population of 363 personnel, working in medical records departments of hospitals affiliated to Tehran University of Medical Sciences, was selected. Users' perception of applying information technology was studied by a researcher-developed questionnaire. Collected data were analyzed by SPSS software (version16) using descriptive statistics and regression analysis. The results suggest that TAM is a useful construct to assess user acceptance of information technology in the context of HIM. The findings also evidenced the perceived ease of use (PEOU) and perceived usefulness (PE) were positively associated with favorable users' attitudes towards HIM. PU was relatively more associated (r= 0.22, p = 0.05) than PEOU (r = 0.014, p = 0.05) with favorable user attitudes towards HIM. Users' perception of usefulness and ease of use are important determinants providing the incentive for users to accept information technologies when the application of a successful HIM system is attempted. The findings of the present study suggest that user acceptance is a key element and should subsequently be the major concern of health organizations and health policy makers.

    L’histoire des tombes et cimetières éthiopiens, dans la longue durée, en est encore à ses balbutiements. Si les tombes des saints et des rois nous sont un peu mieux connus grâce à des textes témoignant à la fois des enjeux entourant les sépultures de ces personnages hors du commun et des soins apportés à leur inhumation, en revanche, les cimetières ordinaires échappent encore largement à l’enquête, en grande partie parce que le commun des mortels est inhumé dans l’anonymat et dans un grand dé...

Une attention particulière est portée aux lois de comportement mécanique et à la détermination de leurs paramètres par des essais in situ et en laboratoire, et l'ouvrage offre également une présentation détaillée des systèmes de classi...

  1. Public's perception and judgment on nuclear power

    International Nuclear Information System (INIS)

    Choi, Young Sung; Kim, Jong Seok; Lee, Byung Wook

    2000-01-01

    A public's perception and judgment model on nuclear power is developed to reveal the structure of public acceptance toward nuclear power in Korea. This is somewhat a verification of an earlier study by the author using two independent sets of survey data. A perception model makes it possible to construct two major exploratory variables, perceived risk and perceived benefit. The difference of perception is analyzed for different groups such as gender, education difference, and different information channels. A judgment model helps identify influential factors that improve the acceptance of nuclear energy. Estimates of model parameters from independent data sets were not significantly different, which implies the validity of the model. Methodologies of this study can be used as the basis for investigating the structure of public perception of technological risks and benefits, designing a public information and risk communication program, and developing remedial policy actions to improve public acceptance

    Behaviour management techniques (BMTs) are utilised by dentists to aid children's dental anxiety (DA). Children's perceptions of these have been underexplored, and their feedback could help inform paediatric dentistry. To explore children's acceptability and perceptions of dental communication and BMTs and to compare these by age, gender, and DA. A total of sixty-two 9- to 11-year-old school children participated in the study. Children's acceptability of BMTs was quantified using a newly developed Likert scale, alongside exploration of children's experiences and perceptions through interviews. anova and t-tests explored BMT acceptability ratings by age, gender, and DA. Thematic analysis was used to analyse interviews. Statistical analyses showed no effect of age, gender, or DA upon BMT acceptability. Children generally perceived the BMTs as acceptable or neutral; stop signals were the most acceptable, and voice control the least acceptable BMT. Beneficial experiences of distraction and positive reinforcement were common. Children described the positive nature of their dentist's communication and BMT utilisation. Dental anxiety did not affect children's perceptions of BMTs. Children were generally positive about dentist's communication and established BMTs. Children's coping styles may impact perceptions and effectiveness of BMTs and should be explored in future investigations. © 2012 John Wiley & Sons Ltd, BSPD and IAPD.

    2011-01-01

    Full Text Available Background: This study examines the relationship between infertile women’s social skills andtheir perception of their own mothers’ acceptance or rejection, and the role this relationship playsin predicting self-reported depression.Materials and Methods: This was a correlational study. 60 infertile women aged 25 to 35 yearsparticipated in a self-evaluation. A Social Skills Inventory, Parental Acceptance and RejectionQuestionnaire and Beck Depression Inventory were used to measure social skills, acceptancerejection and depression. Data was analyzed by SPSS software, using independent two-sample ttest, logistic regression, and ANOVA.Results: Findings showed that there are significant differences between depressed and not depressedinfertile women in their perceptions of acceptance and rejection by their mothers. Further, women'sperceptions of rejection are a more significant predictor of depression among less socially skilledinfertile women than among those who are more socially skilled. Less socially skilled women didnot show symptoms of depression when they experienced their mothers as accepting. In generalthe results of this study revealed that poorer social skills were more predictive of depression whilegood social skills moderate the effect of infertile women’s perceptions of their mothers' rejection.At the same time, the findings showed that infertile women's perceptions of acceptance moderatedthe effects of poorer social skills in predicting depression.Conclusion: Results suggest that the perception of mothers’ rejection and poor social skills are thekey factors that make infertile women prone to depression.

  8. Risk acceptance in multiple sclerosis patients on natalizumab treatment.

    Directory of Open Access Journals (Sweden)

    Carmen Tur

    Full Text Available OBJECTIVE: We aimed to investigate the ability of natalizumab (NTZ-treated patients to assume treatment-associated risks and the factors involved in such risk acceptance. METHODS: From a total of 185 patients, 114 patients on NTZ as of July 2011 carried out a comprehensive survey. We obtained disease severity perception scores, personality traits' scores, and risk-acceptance scores (RAS so that higher RAS indicated higher risk acceptance. We recorded JC virus status (JCV+/-, prior immunosuppression, NTZ treatment duration, and clinical characteristics. NTZ patients were split into subgroups (A-E, depending on their individual PML risk. Some 22 MS patients on first-line drugs (DMD acted as controls. RESULTS: No differences between treatment groups were observed in disease severity perception and personality traits. RAS were higher in NTZ than in DMD patients (p<0.01. Perception of the own disease as a more severe condition tended to predict higher RAS (p=0.07. Higher neuroticism scores predicted higher RAS in the NTZ group as a whole (p=0.04, and in high PML-risk subgroups (A-B (p=0.02. In low PML-risk subgroups (C-E, higher RAS were associated with a JCV+ status (p=0.01. Neither disability scores nor pre-treatment relapse rate predicted RAS in either group. CONCLUSIONS: Risk acceptance is a multifactorial phenomenon, which might be partly explained by an adaptive process, in light of the higher risk acceptance amongst NTZ-treated patients and, especially, amongst those who are JCV seropositive but still have low PML risk, but which seems also intimately related to personality traits.

    Science.gov (United States)

    Benoit, Louis

    En 1984 Belavin, Polyakov et Zamolodchikov revolutionnent la theorie des champs en explicitant une nouvelle gamme de theories, les theories quantiques des champs bidimensionnelles invariantes sous les transformations conformes. L'algebre des transformations conformes de l'espace-temps presente une caracteristique remarquable: en deux dimensions elle possede un nombre infini de generateurs. Cette propriete impose de telles conditions aux fonctions de correlations qu'il est possible de les evaluer sans aucune approximation. Les champs des theories conformes appartiennent a des representations de plus haut poids de l'algebre de Virasoro, une extension centrale de l'algebre conforme du plan. Ces representations sont etiquetees par h, le poids conforme de leur vecteur de plus haut poids, et par la charge centrale c, le facteur de l'extension centrale, commune a toutes les representations d'une meme theorie. Les theories conformes minimales sont constituees d'un nombre fini de representations. Parmi celles-ci se trouvent des theories unitaires dont les representation forment la serie discrete de l'algebre de Virasoro; leur poids h a la forme h_{p,q}(m)=[ (p(m+1) -qm)^2-1] (4m(m+1)), ou p,q et m sont des entiers positifs et p+q= 2. Ces representations possedent un sous-espace invariant engendre par deux sous-representations avec h_1=h_{p,q} + pq et h_2=h_{p,q} + (m-p)(m+1-q) dont chacun des vecteurs de plus haut poids portent le nom de vecteur singulier et sont notes respectivement |Psi _{p,q}> et |Psi_{m-p,m+1-q}>. . Les theories super-conformes sont une version super-symetrique des theories conformes. Leurs champs appartiennent a des representation de plus haut poids de l'algebre de Neveu-Schwarz, une des deux extensions super -symetriques de l'algebre de Virasoro. Les theories super -conformes minimales possedent la meme structure que les theories conformes minimales. Les representations sont elements de la serie h_{p,q}= [ (p(m+2)-qm)^2-4] /(8m(m+2)) ou p,q et m sont

    2011-12-01

    Full Text Available Written feedback on students’ assignments is a common method that instructors and teaching assistants use to inform students about their performance or guide revisions. Despite its frequency of use, written feedback often lacks sufficient detail to be beneficial to students, and additional empirical research should examine its effectiveness as a teaching tool. The current study examined the effectiveness of two different types of feedback, developed and undeveloped, in terms of its influence on students’ subsequent writing performance and students’ perceptions of the feedback. Results demonstrated that the type of feedback significantly affected students’ perceptions, with developed feedback related to higher ratings of fairness and helpfulness; however, this feedback did not have a significant positive effect on students’ written performance.Les commentaires écrits sur les travaux sont une méthode courante utilisée par les enseignants et les aides-enseignants pour renseigner les étudiants sur leurs performances ou pour orienter les révisions. Malgré leur fréquence, il arrive souvent que les commentaires écrits ne soient pas assez détaillés pour être profitables aux étudiants. De plus amples recherches empiriques devraient se pencher sur l’efficacité de cet outil d'enseignement. La présente étude porte sur l'efficacité de différents types de commentaires élaborés et sous-élaborés; sur leur influence sur la performance écrite subséquente des étudiants et sur la perception de ces derniers à propos des commentaires. Les résultats démontrent que le type de commentaires influe significativement sur la perception des étudiants, les commentaires élaborés entraînant des évaluations supérieures en ce qui a trait à l’impartialité et à l'utilité; cependant, ces commentaires n'ont pas d'effets positifs importants sur la performance écrite des étudiants.

    International Nuclear Information System (INIS)

    Whipple, C.

    1997-01-01

    Several alternative approaches to address the question open-quotes How safe is safe enough?close quotes are reviewed and an attempt is made to apply the reasoning behind these approaches to the issue of acceptability of radiation exposures received in space. The approaches to the issue of the acceptability of technological risk described here are primarily analytical, and are drawn from examples in the management of environmental health risks. These include risk-based approaches, in which specific quantitative risk targets determine the acceptability of an activity, and cost-benefit and decision analysis, which generally focus on the estimation and evaluation of risks, benefits and costs, in a framework that balances these factors against each other. These analytical methods tend by their quantitative nature to emphasize the magnitude of risks, costs and alternatives, and to downplay other factors, especially those that are not easily expressed in quantitative terms, that affect acceptance or rejection of risk. Such other factors include the issues of risk perceptions and how and by whom risk decisions are made

    2015-03-01

    Full Text Available This paper shows the results of a research study focused on students’ perception of learning as part of a cooperative MOOC. The course in question is a university MOOC that is included in a regulated Primary Education Teacher training degree programme, although participation is open to any interested parties. The students’ perception is assessed using a TAM (Technology Acceptance Model survey that has been adapted to the learning context in a MOOC. Three variables associated with students’ perception of learning in the course are analysed: the participants’ academic level (degree students versus non-degree students; the type of participation in the course (hidden, moderately hidden, active, individualist and collaborative; and the gender. Although the students’ perception as regards the utility, motivation and user-friendliness of a MOOC is high, certain differences have been found between the analysed variables. Non-degree students are observed to perceive the methodology used in a MOOC more positively. Furthermore, men score significantly higher both in motivation towards learning using MOOCs and in perception of their utility as regards learning. The results show a moderate level of acceptance by the students regarding the use of MOOC in regulated university contexts, and they suggest greater acceptance in learning environments associated with continuous education and professional development.

  19. Differentiated influences of benefit and risk perceptions on nuclear power acceptance according to acceptance levels. Evidence from Korea

    International Nuclear Information System (INIS)

    Roh, Seungkook; Lee Jinwon

    2017-01-01

    The perceived benefit and risk of nuclear power generation have received considerable attention as determinants of the public's nuclear power acceptance. However, the contingency of the relative importance of these benefit and risk has been less explored. Using Korea as an example, this study explores the possibility that the relative importance of perceived benefit and risk on nuclear power acceptance depends on acceptance levels. Our results from latent class analysis and multinomial probit show that, in determining whether an individual shows a moderate level of nuclear power acceptance rather than a low level, perceived risk plays a dominant role compared to perceived benefit; however, regarding whether he/she shows a high level of nuclear power acceptance rather than a moderate level, this relative importance is reversed. These results carry practical implications for risk governance of nuclear power, particularly with regard to communication with the public. (author)

Les êtres humains, lancés par un pertuis de chair dans le chaos du monde, acceptent leurs destins collectifs par ces formes en résonnance. Naître au monde, c’est refuser et accepter tout à la fois des contractions et des contradictions mythiques, qui vont nourrir aléatoirement une substance intime.

Répondre à la question “qui invente les mythes?” est donc un exercice difficile : la vérité est la seule chose que l’on peut inventer, sera ma première réponse.

  8. Treatment acceptability and preferences for managing severe health anxiety: Perceptions of internet-delivered cognitive behaviour therapy among primary care patients.

    Soucy, Joelle N; Hadjistavropoulos, Heather D

    2017-12-01

    While cognitive behaviour therapy (CBT) is an established treatment for health anxiety, there are barriers to service access. Internet-delivered cognitive behaviour therapy (ICBT) has demonstrated effectiveness and has the potential to improve access to treatment. Nevertheless, it is unknown how patients perceive ICBT relative to other interventions for health anxiety and what factors predict ICBT acceptability. This study investigated these questions. Primary care patients (N = 116) who reported elevated levels of health anxiety were presented three treatment vignettes that each described a different protocol for health anxiety (i.e., medication, CBT, ICBT). Acceptability and credibility of the treatments were assessed following the presentation of each vignette. Participants then ranked the three treatments and provided a rational for their preferences. The treatments were similarly rated as moderately acceptable. Relative to medication and ICBT, CBT was perceived as the most credible treatment for health anxiety. The highest preference ranks were for CBT and medication. Regression analyses indicated that lower computer anxiety, past medication use, and lower ratings of negative cognitions about difficulty coping with an illness significantly predicted greater ICBT acceptability. Health anxiety was not assessed with a diagnostic interview. Primary care patients were recruited through a Qualtrics panel. Patients did not have direct experience with treatment but learned about treatment options through vignettes. Medication and CBT are preferred over ICBT. If ICBT is to increase treatment access, methods of improving perceptions of this treatment option are needed. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Higher knowledge has long been hypothesized as leading to better acceptance of nuclear energy, but in the last years other factors such as risk perception and trust in nuclear risk governance were also recognized as key elements. While stakeholder involvement is now fully recognized as a key element for nuclear energy acceptance, there are still questions about the impact of higher knowledge. This paper investigates the relation between knowledge about the nuclear domain, risk perception of nuclear risks, confidence in the management of nuclear technologies, on the one hand, and the attitude towards nuclear energy and opinion about nuclear energy, on the other hand. It also studies the factors that are pleading in favour or against nuclear energy and their relation with the forementioned variables. The study is based on empirical data from a large scale opinion survey in Belgium between 25/05/2011 and 24/06/2011, i.e. the third month after the accident in Fukushima. The sample consisted of 1020 respondents and is representative for the Belgian adult population (18+) with respect to gender, age, region, province, habitat and social class. Our results show that confidence in the safe management of nuclear technologies as well as the perceived strength of the arguments pro/against nuclear are driving factors for people's attitude towards nuclear energy. Higher confidence and stronger adherence to the arguments in favour of nuclear energy lead to higher acceptance. The correlation between knowledge and attitude/opinion towards nuclear energy is statistically significant, but rather low, showing only a weak effect of knowledge on attitudes or opinions about nuclear energy. A weak effect is also observed for risk perception of nuclear risks, lower risk perception leading to a somewhat more positive attitude/opinion about nuclear energy. In the study we also highlight that the main factors seen as pleading in favour or against nuclear energy are the same, both for

    Full Text Available Background: Malnutrition in children less than 5 years old persists around the world. In West Java and one of the districts of West Java (Sumedang, the prevalence of malnutrition is about 18.5% and 15.8% respectively. Numerous factors can lead to child malnutrition. Difficulties in availability, accessibility, acceptability and quality of food can be contributing factors. A good perception of mother on adequate nutrition can improve children’s nutritional status. This study was conducted to study the perception of mothers with children 2 to 5 years old on adequate nutrition. Methods: Most of the respondents had good perception on the aspect of adequate nutrition. Results showed perception on availability was 83.8%, physical accessibility was 97.1%, economical accessibility was 98.6%, information accessibility was 84.8% and acceptability was 81.0%. However, perception of respondents on good quality nutrition for the main meal and additional food was still poor. Moreover, there are taboos for eating shrimp and watermelon. Additionally, children were given snacks in large amount. Results: There was a strong correlation between mid-upper arm muscle area/size and muscular strength (correlation cooefficient 0.746. Moreover, the higher the Body Mass Index, the stronger the muscle strength was to some point. If the BMI was more than 25 kg/m2, this findings did not occurred. Conclusions: This study reveals that the perception of mothers on good quality food is poor regardless the good results on availibility, accesibility and acceptability.

    Community acceptance has been identified as one of the key requirements for a sustainable bioenergy project. However less attention has been paid to this aspect from developing nations and small projects perspective. Therefore this research examines the role of community acceptance for sustainable small scale bioenergy projects in India. While addressing the aim, this work identifies influence of community over bioenergy projects, major concerns of communities regarding bioenergy projects and factors influencing perceptions of communities about bioenergy projects. The empirical research was carried out on four bioenergy companies in India as case studies. It has been identified that communities have significant influence over bioenergy projects in India. Local air pollution, inappropriate storage of by-products and credibility of developer are identified as some of the important concerns. Local energy needs, benefits to community from bioenergy companies, level of trust on company and relationship between company and the community are some of the prime factors which influence community's perception on bioenergy projects. This research sheds light on important aspects related to community acceptance of bioenergy projects, and this information would help practitioners in understanding the community perceptions and take appropriate actions to satisfy them

    des abus (pilulomanie. Les services d'intervention doivent accorder une attention particulière à la prise de substances psycho­actives. Toute consommation entraîne un risque et toutes les substances, en fonction de la fréquence de leur consommation, ont le potentiel d' engendrer une dépendance. Étant donné que rien ne prouve l'effet bénéfique de la consommation de ces substances, que la consommation soit occasionnelle ou bien au gré des situations, nous croyons que les spécialistes en addictologie doivent faire partie des équipes rattachées aux centres ou services médicaux. Consommer ces substances c' est fuir les problèmes et non pas les affronter. Les stratégies qui aident à faire face aux expériences de vie négatives et à renforcer les capacités de les surmonter seraient, entre autres, la technique d' exposition, la planification de surmonter les difficultés, la sollicitation du soutien social, l' acquisition de la maîtrise de soi, l' acceptation, l' acquisition des techniques de contrôle du stress.

    Le travail presente ici est un bilan du travaux de recherche effectues sur l'injectabilite des coulis de ciment dans lu milieux fissures. Un certain nombre de coulis a base de ciment Portland et microfin ont ete selectionnes afin de caracteriser leur capacite a penetrer des milieux fissures. Une partie des essais a ete menee en laboratoire. L'etude rheologique des differents melanges a permis de tester l'influence de l'ajout de superplastifiant et/ou de fumee de silice sur la distribution granulometrique des coulis et par consequent sur leur capacite a injecter des colonnes de sable simulant un milieu fissure donne. La classe granulometrique d'un coulis, sa stabilite et sa fluidite sont apparus comme les trois facteurs principaux pour la reussite d'une injection. Un facteur de finesse a ete defini au cours de cette etude: base sur la classe granulometrique du ciment et sa stabilite, il peut entrer dans la formulation theorique du debit d'injection avant application sur chantier. La deuxieme et derniere partie de l'etude presente les resultats de deux projets de recherche sur l'injection realises sur chantier. L'injection de dalles de beton fissurees a permis le suivi de l'evolution des pressions avec la distance au point d'injection. L'injection de murs de maconnerie a caractere historique a montre l'importance de la definition de criteres de performance des coulis a utiliser pour traiter un milieu donne et pour un objectif donne. Plusieurs melanges peuvent ainsi etre predefinis et mis a disposition sur le chantier. La complementarite des ciments traditionnels et des ciments microfins devient alors un atout important. Le choix d'utilisation de ces melanges est fonction du terrain rencontre. En conclusion, cette recherche etablit une methodologie pour la selection des coulis a base de ciment et des pressions d'injection en fonction de l'ouverture des fissures ou joints de construction.

    To evaluate the effectiveness of the Acceptance Journeys social marketing campaign to reduce homophobia in the Black community in Milwaukee, Wisconsin. We assessed the campaign's effectiveness using a rolling cross-sectional survey. Data were collected annually online between 2011 and 2015. Each year, a unique sample of Black and White adults, aged 30 years and older, were surveyed in the treatment city (Milwaukee) and in 2 comparison cities that did not have antihomophobia campaigns (St. Louis, MO, and Cleveland, OH; for total sample, n = 3592). Black self-identification and Milwaukee residence were significantly associated with exposure to the campaign, suggesting successful message targeting. The relationship between exposure and acceptance of gay men was significantly mediated through attitudes toward gay men, perceptions of community acceptance, and perceptions of the impact of stigma on gay men, but not through rejection of stereotypes. This model accounted for 39% of variance in acceptance. This evidence suggests that the Acceptance Journeys model of social marketing may be a promising strategy for addressing homophobia in US Black communities.

    A between-groups experimental design examined public acceptance for managed aquifer recharge of storm water for indirect potable and nonpotable reuse; acceptance was based on five policy-related variables (fairness, effectiveness, trust, importance of safety assurances, and importance of communication activities). Results showed that public acceptance (N = 408) for managed aquifer recharge of storm water was higher for nonpotable applications, as was the importance of safety assurances. Analyses of variance also showed that perceptions of fairness and effectiveness were higher for a nonpotable scheme, but not trust. A three-step hierarchical regression (Step 1: age, gender, education, and income; Step 2: type of use; Step 3: fairness, effectiveness, trust, safety assurance, and communication activities) demonstrated that type of storm water use and the policy-related factors accounted for 73% of the variance in acceptance of storm water (R2 = 0.74, adjusted R2 = 0.74, F (10, 397) = 113.919, p important predictors were perceptions of trust in water authorities, perceptions of effectiveness, and perceptions of fairness. Interestingly, while safety assurance was important in attitudinal acceptance of managed aquifer recharge based on type of use, safety assurance was not found to be significant predictor of acceptance. This research suggests that policy-makers should look to address matters of greater public importance and drive such as fairness, trust, and effectiveness of storm water programs and advocate these at the forefront of their policies, rather than solely on education campaigns.

    One of the main constraints to adopt a nuclear program is the public acceptance. In Mexico, at least, it lacks of an adequate promotion of its benefits and challenges. A big stigma for nuclear electricity production is the association with nuclear weapons, along with myths and misconceptions and bad information about nuclear energy. Mexico has adopted an energy policy to diversify the electricity sources and nuclear energy is among the alternatives to achieve this goal because current studies show that is a safe and a competitive option from an economical point of view. Public opinion plays a very important role in the policy decision making to adopt the deployment of new reactor units; therefore it is necessary to define communication strategies to promote nuclear energy. The current study is an investigation to learn what is the perception and positioning about nuclear energy as a starting point to define the way to improve public acceptance. The national assessment carry on here is divided in two parts, the first one is a qualitative study to know knowledge level, associations and nuclear perception, identifying controversy items and expectations about advantages and disadvantages to define the adequate question to be used in the second part, which is a quantitative study that shows the acceptance of nuclear energy at national level and in particular in two sites that are suitable to deploy new nuclear reactors. From the results of this study some communication and persuasion strategies to improve public perception are defined and they could be used as part of a nuclear program. (author)

Il compare trois collections de guides français : les Guides Joanne, les Guides Bleus Hachette et les Guides Verts Michelin. Nous avons identifié trois moments majeurs. Dans une première période, le voyage en chemin de fer détermine une représentation linéaire de l’espace agrémentée de quelques coups d’œil à l’intérieur du paysage à l’endroit des stations. Dans une seconde période, le déplacement en voiture permet à une appréhension régionale de se développer. L’école française de géographie influence alors l’écriture des introductions de guide. Les rédacteurs introduisent de plus en plus de cartes dans ces ouvrages. L’unité régionale devient sensible, notamment du point de vue naturaliste. Toutefois, la recherche des curiosités, musées églises, châteaux et ruines se maintient également. De nos jours, l’autoroute, le train à grande vitesse et l’industrie touristique ont changé les pratiques et représentations de l’espace. Les touristes semblent apprécier le fait de collectionner les sites de visite et de faire des circuits à thème.This article deals with tourist perception of the space from the end of the nineteenth century to our days. It compares three collections of French tourist guides: Guides Joanne, blue guides Hachette and Guides Verts Michelin. Three main periods can be distinguished. First, railway travel determines linear representation of the landscape, with a few glances on the countryside at the stations. In a second period, the car mobility makes possible a surrounding vision of regions. French school of geography influences the prefaces of the guides. Editors introduce more and more maps inside the guides. Regional cohesion becomes perceptible, especially from a naturalistic point of view. Interesting sights, museums, churches, castles and ruins remain

    Full Text Available Introduction. Malgré la protection juridique dont les jeunes travailleurs au Canada font l’objet, les jeunes de 15 à 24 ans sont exposés à un risque élevé de blessures traumatiques au travail. Étant donné que de nombreuses initiatives de prévention des blessures ciblant les jeunes travailleurs existent, les défenseurs des droits des jeunes et les employeurs doivent relever le défi de choisir quels aspects de la prévention vont être les plus efficaces afin d’y consacrer leurs efforts. Une analyse de la littérature universitaire et de la littérature grise a été entreprise afin de compiler les paramètres (indicateurs évalués et méthodes de mesure couramment utilisés pour évaluer les programmes de prévention des blessures auprès des jeunes travailleurs. Les paramètres constituent des références de mesure permettant d’évaluer l’efficacité, le rendement, le progrès ou la qualité d’un projet, d’un procédé ou d’un produit. Méthodologie. Nous avons utilisé le modèle PICO pour définir les termes de recherche. Des recherches ont été effectuées dans Medline, PubMed, OVID, EMBASE, CCOHS, PsychINFO, CINAHL, NIOSHTIC, Google Scholar et dans la littérature grise afin de trouver des articles en anglais publiés entre 1975 et 2015. Deux lecteurs critiques indépendants ont examiné la liste des articles et ont classé les paramètres en trois catégories de prévention des blessures : l’éducation, l’environnement et l’application de règlements. Résultats. Sur les 174 articles ayant répondu aux critères d’inclusion, 21 décrivaient et évaluaient une intervention. Parmi ceux-ci, la moitié (n=11 étaient à caractère éducatif. Les paramètres couramment évalués étaient : les connaissances, les perceptions, les comportements ou les intentions autodéclarées, l’exposition aux dangers, les demandes d’indemnisation pour blessures et le taux d’accidents de travail.

    Full Text Available Les facteurs organoleptiques des aliments conditionnent la prise alimentaire. L’aspect croquant, une de ces qualités sensorielles qui peut être définie comme la sonorité en bouche, est encore peu étudié. Comment ce critère intervient-il dans le choix de variétés de pain et de pomme, couramment consommées en France, leur appréciation et leur consommation ? Une étude a été menée auprès d’enfants de la région parisienne, 162 pour le pain, 132 pour la pomme, garçons et filles de 6 à 12 ans. Ils ont participé à un test de dégustation (perception et appréciation de deux sortes de pain, baguette et pain de seigle, ou de deux variétés de pomme, Granny Smith et Red Chief, et ils ont répondu à un questionnaire portant sur leur consommation de pains ou de pommes et sur diverses attitudes sensorielles. Les réponses obtenues ont été homogènes, ne variant pas en fonction de l’âge et du sexe. Les enfants se reconnaissent sensibles à la sonorité croquante du pain ou des pommes. Ils disent que l’aspect croquant fait partie des critères d’appréciation des pains ou des pommes, au même titre que d’autres critères, la couleur, la forme, la prise en main, le goût et l’odeur mais ils ne le situent pas tout à fait au même rang, ce qui témoigne de la particularité sensorielle de chacun de ces aliments. L’aspect croquant pourrait participer à l’évaluation de l’appréciation globale d’un morceau de pain, lors de cette dégustation au moins, alors qu’il ne semble pas intervenir pour l’appréciation des pommes dont les saveurs légèrement sucré ou acide sont immédiatement reconnues. Pour le pain, particulièrement la baguette, à la différence de la pomme, semble intervenir un aspect « craquant » correspondant à la sonorité obtenue lorsqu’il est touché à la main ou rompu avant d’être mordu et mastiqué.Among the organoleptic factors involved in food intake, "crunchiness" is a sensory

As entrevistas mostram finalmente, que uma melhor gestão dos riscos ambientais passará por uma boa consideração do universo técnico e cultural dos agricultores assim como de suas dificuldades econômicas.L’ouest du Rio Grande do Sul est dominé par la culture du soja, du riz et par l’élevage bovin. Dans la partie sableuse, le milieu est affecté par des phénomènes d’érosion produisant des modelés éoliens spectaculaires (arenização rappelant dans l’imaginaire ceux des déserts. La production agricole est importante ce qui engendre des prélèvements d’eau pour l’irrigation du riz, mais aussi l’utilisation de pesticides pour l’ensemble des cultures. La gestion durable des ressources en eau et en sol de cette région nécessite la mise en place d’action de conservation. Mais un certain nombre de questions se posent alors : comment les agriculteurs perçoivent ces phénomènes ? Constituent-ils pour eux des enjeux ? Comment raisonnent-ils leurs pratiques ? Avec quels réseaux ? Quelles sont les interactions avec les pouvoirs publics ?La méthodologie adoptée s’appuie sur des enquêtes ouvertes réalisées auprès de 23 agriculteurs. Il s’agit de mieux comprendre leur perception de l’environnement, leurs modes de gestion et d’identifier les variables sociales au sein de l’échantillon expliquant des différences de comportement.Les résultats que nous avons obtenus montrent que peu d’agriculteurs perçoivent leurs responsabilités quant à l’érosion des sols et à l’état des ressources en eau. Si des risques de manque d’eau sont perçus par certains, ils sont attribués essentiellement à la sécheresse et non à une surexploitation des ressources, la pollution est négligée.

    Several countries are currently discussing whether they will rebuild their nuclear power stations in order to continue this type of energy production in the future. The public, with its own opinion about nuclear power stations, has an influential voice in this discussion. As a result, policy makers and nuclear scientists are interested in the public's perception of nuclear power and in what determines this perception. We therefore examined an explanatory model of the public's acceptance of nuclear power based on a telephone survey among a representative sample in Switzerland. The model included such factors as risk perception, benefit perception, affective feelings, and social trust. Moreover, we distinguished between two types of benefit perception: benefit for the climate and a secure energy supply. The model fitted very well to our data and explained acceptance very well. Acceptance was mainly influenced by perceived benefits for a secure energy supply and, to a lesser extent, both by perceived benefits for the climate and by risk perception. Affective feelings about nuclear power appeared to be a central factor in the model. Implications for communication about nuclear power stations and for further research are discussed. - Highlights: → Explanatory model of determinants of nuclear power acceptance was studied in the representative survey. → Perceived benefits for a secure energy supply had the largest influence on acceptance. → Perceived benefits for the climate seemed less influential on acceptance. → Affect had a central role in the explanatory model. → Implications for communication about nuclear power plants are discussed.

    Résumé Objectif Effectuer une révision systématique des effets de repas en famille fréquents sur les résultats psychosociaux chez les enfants et les adolescents et examiner s’il existe des différences dans les résultats selon le sexe. Sources des données Des études ont été cernées à la suite d’une recherche dans MEDLINE (de 1948 à la dernière semaine de juin 2011) et dans PsycINFO (de 1806 à la première semaine de juillet 2011) à l’aide de l’interface Ovide. Les expressions et mots clés MeSH utilisés seuls ou en combinaisons étaient les suivants : family, meal, food intake, nutrition, diets, body weight, adolescent attitudes, eating behaviour, feeding behaviour et eating disorders. Les bibliographies des articles jugés pertinents ont aussi été passées en revus. Sélection des études La recherche initiale a produit 1783 articles. Pour être incluses dans l’analyse, les études devaient répondre aux critères suivants : être publiées en anglais dans une revue révisée par des pairs; porter sur des enfants ou des adolescents; traiter de l’influence des repas en famille sur les paramètres psychosociaux (p. ex. consommation de drogues et autres substances, troubles de l’alimentation, dépression) chez les enfants ou les adolescents; avoir une conception d’étude appropriée, notamment des méthodes statistiques acceptables pour l’analyse des paramètres. Quatorze articles satisfaisaient aux critères d’inclusion. Deux examinateurs indépendants ont étudié et analysé les articles. Synthèse Dans l’ensemble, les résultats font valoir que la fréquence des repas en famille est inversement proportionnelle aux troubles de l’alimentation, à la consommation d’alcool et de drogues, aux comportements violents, aux sentiments de dépression ou aux pensées suicidaires chez les adolescents. Il existe une relation positive entre de fréquents repas en famille, une bonne estime de soi et la réussite scolaire. Les

    Vector and malaria parasite's rising resistance against pyrethroid-impregnated bed nets and antimalarial drugs highlight the need for additional control measures. Larviciding against malaria vectors is experiencing a renaissance with the availability of environmentally friendly and target species-specific larvicides. In this study, we analyse the perception and acceptability of spraying surface water collections with the biological larvicide Bacillus thuringiensis israelensis in a single health district in Burkina Faso. A total of 12 focus group discussions and 12 key informant interviews were performed in 10 rural villages provided with coverage of various larvicide treatments (all breeding sites treated, the most productive breeding sites treated, and untreated control). Respondents' knowledge about the major risk factors for malaria transmission was generally good. Most interviewees stated they performed personal protective measures against vector mosquitoes including the use of bed nets and sometimes mosquito coils and traditional repellents. The acceptance of larviciding in and around the villages was high and the majority of respondents reported a relief in mosquito nuisance and malarial episodes. There was high interest in the project and demand for future continuation. This study showed that larviciding interventions received positive resonance from the population. People showed a willingness to be involved and financially support the program. The positive environment with high acceptance for larviciding programs would facilitate routine implementation. An essential factor for the future success of such programs would be inclusion in regional or national malaria control guidelines.

    Acceptance of background noise can be evaluated by having listeners indicate the highest background noise level (BNL) they are willing to accept while following the words of a story presented at their most comfortable listening level (MCL). The difference between the selected MCL and BNL is termed the acceptable noise level (ANL). One of the consistent findings in previous studies of ANL is large intersubject variability in acceptance of background noise. This variability is not related to age, gender, hearing sensitivity, personality, type of background noise, or speech perception in noise performance. The purpose of the current experiment was to determine if individual differences in physiological activity measured from the peripheral and central auditory systems of young female adults with normal hearing can account for the variability observed in ANL. Correlations between ANL and various physiological responses, including spontaneous, click-evoked, and distortion-product otoacoustic emissions, auditory brainstem and middle latency evoked potentials, and electroencephalography will be presented. Results may increase understanding of the regions of the auditory system that contribute to individual noise acceptance.

  13. Residential proximinity, perceived and acceptable risk

    International Nuclear Information System (INIS)

    Rogers, G.O.

    1984-01-01

    This paper focuses on the relationship between the life experiences associated with residential proximity, and the perception and acceptability of the risks associated with generating electricity in nuclear power plants. Perceived risk is operationally defined in terms of estimated likelihood of occurrence, while acceptability of nuclear power is defined in terms of people's favorable or unfavorable opinions regarding nuclear power plants. In the context of a simple social-structural model of perceived and acceptable risk, four potential explanations for enhanced acceptability among those residentially proximate with nuclear facilities are examined: residents, through the experience of living with hazard, are reinforced toward assigning lower probabilities to the potential risks associated with nuclear facilities; the cognitive dissonance created by the acceptance of the risks associated with nuclear power is decreased by reducing perceived risk; nuclear neighbors are predisposed toward, educated about, and/or economically dependent upon nuclear power hence the more favorable attitudes toward it; nearby residents are systematically more altruistic--other oriented--than the general population and thus more willing to bear the risks associated with nuclear power

    To examine the perceptions of staff members toward the implementation of an animal-assisted activity (AAA) in an outpatient regional cancer center. Quasi-experimental, post-test design. An adult outpatient regional cancer center in northern California. 34 facility staff members. Self-report questionnaire following four weeks of AAA visitation. Visits took place three times a week for a total of 12 visits. Perceptions of the AAA. Previous perceptions toward AAA influenced the perceptions of the visitation's efficacy. Direct and indirect interaction with the visiting AAA teams was positively associated with perceptions of the AAA. A disagreement occurred that the AAA had caused extra stress or work for staff. Enjoyment of interacting with the dog handler was not significantly different from interacting with the dog; however, it was more positively correlated to acceptance of the AAA. The study provided evidence that the AAA was generally accepted by staff members. Individual staff members' perceptions of dogs and AAAs can influence their receptivity to AAA interventions. Interaction with AAA teams should be voluntary and available for patients and staff members. AAA may be introduced into facilities without creating the perception of extra stress or work for staff members. Providing staff the opportunity to interact with visiting AAA teams may be beneficial for the success of such programs. The human handler in AAA teams may play a vital role in the staff acceptance of such programs.

En ce sens, le défi de la qualité est aussi important dans les MOOC que dans le domaine de la FAD. La présente recherche a pour objectif d’examiner l’appréciation que 631 apprenants font de leur expérience de deux MOOC du HEC Montréal, à partir de leurs perceptions et d’une approche inductive non préalablement fondée sur des a priori théoriques, à l’aide de trois questions ouvertes. Il émerge des résultats des critères d’évaluation se rapprochant de ceux utilisés dans les cadres de qualité en FAD, mais opérationnalisés d’une manière très spécifique. Ainsi, une attention toute particulière devrait être accordée au contenu (liens théorie-pratique, accessibilité des contenus, aux prestations enseignantes et à la clarté des tests.

  1. Understanding diversity: the importance of social acceptance.

    Science.gov (United States)

    Chen, Jacqueline M; Hamilton, David L

    2015-04-01

    Two studies investigated how people define and perceive diversity in the historically majority-group dominated contexts of business and academia. We hypothesized that individuals construe diversity as both the numeric representation of racial minorities and the social acceptance of racial minorities within a group. In Study 1, undergraduates' (especially minorities') perceptions of campus diversity were predicted by perceived social acceptance on a college campus, above and beyond perceived minority representation. Study 2 showed that increases in a company's representation and social acceptance independently led to increases in perceived diversity of the company among Whites. Among non-Whites, representation and social acceptance only increased perceived diversity of the company when both qualities were high. Together these findings demonstrate the importance of both representation and social acceptance to the achievement of diversity in groups and that perceiver race influences the relative importance of these two components of diversity. © 2015 by the Society for Personality and Social Psychology, Inc.

    Résumé La politique actuelle de lutte contre le sida qui repose sur l’extension de l’accès aux traitements et à la prévention exige qu’une proportion élevée de la population connaisse son statut en matière de VIH. Pour cela, l’OMS a proposé le développement de stratégies communautaires délivrant le dépistage et le conseil au-delà des services de soins, comme le test à domicile ou les campagnes de sensibilisation et dépistage de grande envergure, appliqués en Afrique australe et de l’Est. Pour définir les stratégies pertinentes dans des régions de basse prévalence comme l’Afrique de l’Ouest, les expériences communautaires de promotion du dépistage doivent y être évaluées. Cet article présente une évaluation des campagnes au Burkina Faso du point de vue des usagers. Dans le cadre d’un projet sur les pratiques et l’éthique du dépistage dans quatre pays africains (MATCH), une enquête qualitative spécifique a été menée pendant la campagne de 2008, auprès de personnes ayant fait le test pendant la campagne, ayant fait le test hors campagne ou n’ayant pas fait le test. Les appréciations sont globalement très favorables aux campagnes, notamment à cause de l’information dispensée, l’accessibilité des sites, la gratuité du test, la qualité des services et l’effet d’entrainement. Les limites ou critiques sont essentiellement liées à l’affluence ou à la crainte de ne pas être soutenu en cas de résultat positif. La démarche de recours au test ne fait plus l’objet de suspicion, au moins pendant la campagne. Cette « normalisation » du recours au test et la mobilisation collective facilitent des pratiques en groupe, ce qui peut rendre difficile de garder son statut VIH secret. L’évaluation des campagnes par les usagers les présente comme une opportunité pour accéder facilement au test et pour communiquer à ce sujet dans divers espaces sociaux à partir des informations délivrées sur le VIH

    2017-01-01

    This book presents an alternative approach to studying smartphone-app user notifications. It starts with insights into user acceptance of mobile notifications in order to provide tools to support users in managing these. It extends previous research by investigating factors that influence users’ perception of notifications and proposes tools addressing the shortcomings of current systems. It presents a technical framework and testbed as an approach for evaluating the usage of mobile applications and notifications, and then discusses a series of studies based on this framework that investigate factors influencing users’ perceptions of mobile notifications. Lastly, a set of design guidelines for the usage of mobile notifications is derived that can be employed to support users in handling notifications on smartphones.

    2011-01-01

    This study examined the dual roles of adolescents’ perceptions of social acceptance and sociometric popularity in predicting relative changes over time in adolescents’ social functioning. Observational, self-report, and peer report data were obtained from 164 adolescents who were interviewed at age 13 years and then again at age 14 years, as well as their same-sex close friends. Adolescents who felt positively about their own social standing fared well over time, regardless of their level of sociometric popularity. Further, low popularity was particularly problematic for adolescents who failed to see themselves as fitting in. Results suggest that during adolescence, when it becomes increasingly possible for teens to choose their own social niches, it is possible to be socially successful without being broadly popular.

    Hodler, J. [Orthopaedische Universitaetsklinik Balgrist, Zuerich (Switzerland)

    1996-12-01

    This article reviews the pathogenesis and clinical and imaging findings in shoulder impingement syndrome. Different stages of impingement syndrome are described. Stage I relates to edema and hemorrhage of the supraspinatus tendon. Stage II is characterized by bursal inflammation and fibrosis, as well as tendinopathy. In stage III there is a tear of the rotator cuff. Clinical signs many overlap. Moreover, calcifying tendinitis, fractures and pain originating from the cervical spine may mimic shoulder impingement syndrome. Imaging is important for the exact diagnosis. Standard radiographs are the basis of imaging in shoulder impingement syndrome. They may demonstrate subchondral sclerosis of the major tuberosity, subacromial spurs, and form anomalies of the acromion. They are also important in the differential diagnosis of shoulder impingement syndrome and demonstrate calcifying tendinitis, fractures and neoplasm. Ultrasonography has found acceptance as a screening tool and even as a final diagnostic method by many authors. However, there is a high interobserver variability in the demonstration of rotator cuff tears. Its usefulness has therefore been questioned. MR imaging is probably the method of choice in the evaluation of the rotator cuff and surrounding structures. Several investigations have demonstrated that differentiation of early findings, such as tendinopathy versus partial tears, may be difficult with MR imaging. However, reproducibility for fullthickness tears appears to be higher than for sonography. Moreover, specificity appears to be superior to sonography. MR arthrography is not universally accepted. However, it allows for more exact differentiation of discrete findings and may be indicated in preoperative planning. Standard arthrography and CT have a limited role in the current assessment of the rotator cuff. (orig.)

    Full Text Available Technology Acceptance Model (TAM is a measure to assess the underlying reasons about the use of a technology. In this study an extended version of TAM were used. This extended version composed of three factors. These are “perceived motivation towards learning environment”, “perceived usefulness” and “perceived ease of use”. In this study, the learning environment of a distance course was investigated to see students’ perceptions. This distance course was delivered from one university to the other university via video-conferencing with ITL Learning Gateway content management system during the whole semester. The participants were the 32 first year vocational higher education institution students. The descriptive findings revealed that each factor of TAM perceived by students as having moderate advantages. It is believed that the underlying reason of this situation was based on the students’ low computer competency and e-learning experiences.

    Full Text Available Il existe dans les bases de données publiques une énorme quantité de séquences d’ADN dérivées de plantes, et notamment la séquence complète du génome d’Arabidopsis thaliana, une plante modèle pour les oléagineux, proche parente du colza. Ces données constituent une ressource importante non seulement pour la compréhension de métabolisme lipidique et de sa régulation, mais aussi pour la sélection et le développement de variétés nouvelles d’oléagineux produisant davantage d’huiles ou des huiles de composition nouvelle. Cette abondance de séquences peut être exploitée, en utilisant les recherches d’homologies, pour identifier les gènes, pour obtenir des informations sur leur fonction, comme pour repérer des gènes candidats codant des fonctions nouvelles. L’analyse de ces bases de données a révélé que la majeure partie des gènes codant des enzymes impliquées dans le métabolisme lipidique appartient à des petites familles multigéniques, reflétant la diversification des fonctions des isoformes. Une analyse du catalogue des ADNc séquencés en aveugle reflète les niveaux d’expression des différents gènes et fournit un aperçu des régulations des flux au travers des voies métaboliques conduisant à la biosynthèse des lipides de réserve. La disponibilité de mutants et de lignées transgéniques d’Arabidopsis et le développement de puces à ADN qui permettent l’analyse simultanée de plusieurs milliers de gènes conduiront à une meilleure compréhension des facteurs qui régulent le métabolisme des huiles dans les graines. Une telle connaissance facilitera la manipulation de la composition des huiles et des quantités produites dans les graines.

    La fabrication de l'aluminium est realisee dans une cellule d'electrolyse, et cette operation utilise des anodes en carbone. L'evaluation de la qualite de ces anodes reste indispensable avant leur utilisation. La presence des fissures dans les anodes provoque une perturbation du procede l'electrolyse et une diminution de sa performance. Ce projet a ete entrepris pour determiner l'impact des differents parametres de procedes de fabrication des anodes sur la fissuration des anodes denses. Ces parametres incluent ceux de la fabrication des anodes crues, des proprietes des matieres premieres et de la cuisson. Une recherche bibliographique a ete effectuee sur tous les aspects de la fissuration des anodes en carbone pour compiler les travaux anterieurs. Une methodologie detaillee a ete mise au point pour faciliter le deroulement des travaux et atteindre les objectifs vises. La majorite de ce document est reservee pour la discussion des resultats obtenus au laboratoire de l'UQAC et au niveau industriel. Concernant les etudes realisees a l'UQAC, une partie des travaux experimentaux est reservee a la recherche des differents mecanismes de fissuration dans les anodes denses utilisees dans l'industrie d'aluminium. L'approche etait d'abord basee sur la caracterisation qualitative du mecanisme de la fissuration en surface et en profondeur. Puis, une caracterisation quantitative a ete realisee pour la determination de la distribution de la largeur de la fissure sur toute sa longueur, ainsi que le pourcentage de sa surface par rapport a la surface totale de l'echantillon. Cette etude a ete realisee par le biais de la technique d'analyse d'image utilisee pour caracteriser la fissuration d'un echantillon d'anode cuite. L'analyse surfacique et en profondeur de cet echantillon a permis de voir clairement la formation des fissures sur une grande partie de la surface analysee. L'autre partie des travaux est basee sur la caracterisation des defauts dans des echantillons d'anodes crues

    Like many other countries in the world, Korea has struggled to site a facility for radioactive waste for almost 30 years because of the strong opposition from local residents. Finally, in 2005, Gyeongju was established as the first Korean site for a radioactive waste facility. The objectives of this research are to verify Gyeongju citizens' average level of risk perception of a radioactive waste disposal facility as compared to other risks, and to explore the best model for predicting respondents' acceptance level using variables related to cost-benefit, risk perception, and political process. For this purpose, a survey is conducted among Gyeongju residents, the results of which are as follows. First, the local residents' risk perception of an accident in a radioactive waste disposal facility is ranked seventh among a total of 13 risks, which implies that nuclear-related risk is not perceived very highly by Gyeongju residents; however, its characteristics are still somewhat negative. Second, the comparative regression analyses show that the cost-benefit and political process models are more suitable for explaining the respondents' level of acceptance than the risk perception model. This may be the result of the current economic depression in Gyeongju, residents' familiarity with the nuclear industry, or cultural characteristics of risk tolerance.

    Full Text Available Je voudrais parler ici des recherches que j'ai effectuées dans le cadre d'un programme de recherches de l'Organisation australienne de recherches (C.S.I.R.O.. Ce sont des recherches sur la structure, la composition chimique et le rôle de la cire cuticulaire des grains de raisins et des feuilles. Ces recherches ont été effectuées principalement lors de l'étude des problèmes relatifs au séchage des raisins pour la production des raisins. Cependant, l'importance de la cire cuticulaire ne se limite pas seulement au séchage des raisins, car elle concerne aussi l'œnologie et les problèmes de la conservation des raisins de table.

    Full Text Available Introduction: The dental profession has been considered a stressful occupation. The origins of this stress may also lie in the process of dental education. The perception of stress is frequently influenced by one′s personal system of beliefs and attitudes. Aim: The aim was to assess the relationship between psychological well-being and perception of stress among undergraduate dental students in Bangalore city. Materials and Methods: A cross-sectional questionnaire survey was conducted among 800 1-4 th year dental students. Information on demographics, social background, and health behaviors were collected. The psychological general well-being (PGWB index and the dental environment stress (DES questionnaire were used to measure PGWB and perceptions of stress, respectively. Multiple intergroup comparisons were carried out using ANOVA. Correlation analysis was done to find out relationship between PGWB and DES. Regression analysis to find out the strongest predictor of PGWB. P <0.05 was considered as statistically significant. Results: There was no significant difference in PGWB among different year of study. Female students had significantly lower PGWB scores and higher DES scores than male students. The stress differed among different year of study with highest stress in final year students in all domains except for clinical/preclinical training, which was highest among 1 st year students. Correlational analysis showed a negative relationship between PGWB and DES score. Stepwise multiple regression analysis revealed that "workload," "patient treatment," "performance pressure" and "others" domains of stress were significant predictors of PGWB. Conclusion: This study revealed that the perception of stress is influenced by gender and health behaviors which in turn affect PGWB.

    Ces dernières décennies, des activités significatives dans le monde étaient dirigées autour du contrôle actif. Le but de ces recherches était essentiellement d'améliorer les performances, la fiabilité et la sécurité des systèmes. Notamment dans le cas des structures soumises à des vibrations aléatoires. D'importants travaux ont été consacré à l'utilisation des “matériaux intelligents” comme capteurs et actionneurs. Cette article propose l'analyse de la fiabilité des systèmes mécaniques en étudiant les pannes des actionneurs ou des capteurs. L'effet de ces pannes sur la stabilité et la performance du système y est démontré. Les méthodologies de conception y sont rappelées. Des exemples numériques sont fournis à travers le contrôle d'un panneau sous chargement dynamique pour illustrer la méthode proposée.

    Full Text Available Workplace based assessment (WPBA is commonplace in postgraduate training in many countries but is not widely practised and established in Asia. The WPBA tools that are used by the local programme are Mini-Clinical Examination (Mini-CEX, Directly Observed Practical Skills (DOPSs, Multisource Feedback (MSF, and Case Based Discussion (CBD. This cross-sectional study utilised a questionnaire to obtain feedback from both assessors and trainees. Participants rated the tools on a 5-point scale on validity, reliability, feasibility, educational impact, and acceptability. 30 assessors and 23 trainees participated in the study. The percentages of adequate ratings given by trainees for validity, reliability, feasibility, educational impact, and acceptability were 100%, 99%, 91%, 100%, and 100%, respectively, for all tools. There was no difference in perceptions between trainees and assessors for all WPBA tools except MSF (p<0.05. The common themes that have arisen suggested that applicability of WPBA could be affected by faculty development, endorsement from governing bodies, pervading cultural mindsets, and the complex relationships between doctors and patients; teachers and students; and educators and clinicians. The high level of satisfaction from our respondents indicates that WPBA can be successfully integrated in an Asian postgraduate training programme despite systemic, cultural, and language barriers.

    1995-01-01

    The question of public acceptance of nuclear energy has for years fueled the discussion on social issues. Denial of this acceptance has without doubt delayed, if not altogether prevented, the further development of nuclear energy during the past two decades. Public perception of nuclear energy is still dominated by resent. In the eyes of the German public it is a dangerous and unacceptable technology that deserves to be substituted as soon as possible. The necessity of this is widely agreed, the only unsettled question being how fast it must happen. Sociologists are often reproached for having only created the acceptance problems they purport to analyse. All sociology can do is describe our reality and make suggestions how to cope with social problems more effectively. The sociologist is the herald of social reality: he should neither gloss over nor dramatise things but rather present a real picture of what is happening. With this premise in mind the author attempts to point out possibilities of and limits to a consensus on the valuation of energy systems, particularly that of nuclear energy. (orig./UA) [de

  19. La qualité du lait entre logiques des coopératives et logiques des éleveurs et éleveuses. Introduction d’un analyseur de qualité du lait dans des coopératives laitières du Gharb

    Directory of Open Access Journals (Sweden)

    2014-11-01

    Full Text Available La filière laitière au Maroc demande de plus en plus que les éleveurs fournissent un lait de qualité. Les coopératives de collecte de lait ont souvent à faire face à un problème d’écrémage du lait, qu’elles ne pouvaient pas par le passé gérer faute d’équipements de contrôle adaptés. La Centrale Laitière a accompagné des coopératives de collecte de lait dans l’acquisition d’appareils de mesure rapide de la qualité du lait, qui mesurent entre autres le taux de matière grasse. La présente étude analyse la modification du dispositif de contrôle de qualité suite à l’installation des analyseurs, les effets de cette modification au niveau des coopératives et l’acceptation du nouveau dispositif au niveau des exploitations familiales. L’étude a été effectuée dans trois coopératives du Gharb. Des éleveurs, des éleveuses ainsi que les leaders et personnels des coopératives ont été enquêtés. L’installation de l’analyseur a permis, grâce à la baisse de la pratique de l’écrémage, une baisse des pénalités imposées par la Centrale Laitière aux coopératives, et une augmentation des primes liées à la bonne qualité. Les pratiques d’écrémage ont diminué mais n’ont pas disparu. Les éleveurs et éleveuses se déclarent majoritairement favorables au nouveau dispositif, car il permet une équité entre les éleveurs. Cependant, le fait de livrer du lait non écrémé conduit aussi à une baisse du revenu que certaines femmes obtenaient en vendant elles-mêmes le beurre au marché. Par ailleurs, la Centrale Laitière ne communique pas de façon détaillée les résultats de ses mesures de qualité. Ceci limite la capacité des coopératives à s’engager dans un paiement à la qualité, ce qui constituerait pourtant un élément clé pour garantir la durabilité d’un tel système de contrôle de la qualité.

    Full Text Available Les acides gras produits par hydrolyse chimique des lipides des plantes sont des matériaux de base pour l’industrie des biocarburants, des lubrifiants, des plastiques, des détergents et également des adjuvants de préparations commerciales d’herbicides. Cependant les procédés actuels de production des acides gras sont hautement polluants et coûteux en énergie. Dans ce travail nous développons un nouveau procédé de production des acides gras mettant en œuvre des plantes génétiquement modifiées. Nous avons introduit dans le tabac, retenu comme plante modèle, une construction génétique comprenant un gène de lipase (de la levure Geotrichum candidum sous le contrôle d’un promoteur graine spécifique (promoteur AtEm1 d’Arabidopsis thaliana. Ce promoteur devrait permettre l’expression du gène de lipase au niveau de l’axe embryonnaire tandis que les lipides s’accumulent dans les corps lipidiques des cotylédons. Dans ces conditions, les lipides de la graine devraient être séparés de la lipase par une compartimentation tissulaire et ne pas interférer. Après broyage des graines on peut penser que la mise en contact des lipides et de la lipase conduira à la libération d’acides gras. Plusieurs transformants ont été produits par transfert de gène à l’aide d’Agrobacterium tumefaciens, quelques-uns d’entre eux exprimant, comme attendu, la lipase dans leurs graines. Trois clones (2, 19 et 43 présentent une activité lipase significative et ont été retenus pour des études complémentaires. Cependant l’activité enzymatique observée est faible et certains clones présentent un défaut de compartimentation entre l’enzyme et les lipides se traduisant par la production d’acides gras dans la graine intacte. Lorsque les graines du clone 43 sont broyées dans un tampon, des acides gras sont produits dans le milieu réactionnel, validant le procédé imaginé. De nouvelles constructions réalisées, soit

    RÉSUMÉ Contexte : La présence d’auteurs honorifiques et fantômes ainsi que les intérêts concurrents représentent des difficultés bien documentées, liées à la publication d’articles scientifiques. Il existe des lignes directrices encadrant la rédaction et la publication de manuscrits scientifiques, notamment celles de l’International Committee of Medical Journal Editors (ICMJE). Objectifs : L’objectif principal de cette étude descriptive et transversale visait à recenser les instructions portant sur la paternité des articles et les intérêts concurrents provenant des recommandations aux auteurs des journaux traitant de pratique pharmaceutique. L’objectif secondaire visait à déterminer des mesures correctrices pour une paternité des articles plus transparente. Méthode : La recherche a débuté par l’identification des journaux traitant de pratique pharmaceutique. La consultation des instructions aux auteurs des journaux a permis ensuite de recenser les recommandations destinées à éviter les problèmes de paternité des articles et d’intérêts concurrents. Finalement, les membres de l’équipe de recherche se sont consultés afin de définir des mesures correctrices possibles à l’intention des chercheurs. Résultats : Des 232 journaux traitant de pharmacie, 33 ont été définis comme traitant de pratique pharmaceutique. Un total de 24 (73 %) journaux mentionnaient suivre la politique de l’ICMJE, 14 (42 %) demandaient aux auteurs de remplir un formulaire de déclaration d’intérêts concurrents au moment de la soumission de l’article, 17 (52 %) présentaient une définition de la qualité d’auteur et 5 (15 %) demandaient de détailler les contributions de chaque auteur. Une grille de 40 critères a été élaborée pour définir l’attribution du statut d’auteur. Conclusion : Moins de la moitié des journaux demandait aux auteurs de transmettre un formulaire de déclaration des intérêts concurrents au moment de la

    2012-06-01

    Full Text Available Abstract The present study addresses the perceptions of international teaching assistants regarding the role of language learning tasks using Wimba Voice (WV in aiding the improvement of their second language (L2 oral skills. It specifically examines how this asynchronous computer-mediated communication (CMC technology can foster the development of these learners’ L2 selves. According to Dörnyei (2009, the more clearly learners can envision their future L2 selves, the more motivated they will be to achieve their L2 goals. With increased planning of oral production, access to instructor and peer feedback, and additional opportunities for self-reflection, asynchronous CMC technologies have been found to enable L2 learners to express their thoughts at their own pace and feel more relaxed and confident than in more threatening face-to-face situations (Sun, 2009. The findings suggest that learners have a variety of opinions regarding the role of asynchronous WV tasks in motivating them to develop their L2 oral proficiency. Also, many may prefer oral CMC environments that facilitate interaction and meaning negotiation. Results were inconclusive concerning the effect of WV-based tasks on students' perceptions of their future L2 selves; however, this may have been due to the short time frame in which these activities were employed.

    This study examined the bidirectional (conjoint) longitudinal pathways linking adolescents' body dysmorphic disorder (BDD) symptoms with self- and peer-reported social functioning. Participants were 367 Australian students (45.5% boys, mean age=12.01 years) who participated in two waves of a longitudinal study with a 12-month lag between assessments. Participants self-reported their symptoms characteristic of BDD, and perception of peer acceptance. Classmates reported who was popular and victimized in their grade, and rated their liking (acceptance) of their classmates. In support of both stress exposure and stress generation models, T1 victimization was significantly associated with more symptoms characteristic of BDD at T2 relative to T1, and higher symptom level at T1 was associated with lower perceptions of peer acceptance at T2 relative to T1. These results support the hypothesized bidirectional model, whereby adverse social experiences negatively impact symptoms characteristic of BDD over time, and symptoms also exacerbate low perceptions of peer-acceptance.

    1991-01-01

    Contrasting experiences of public acceptance of radioactive waste disposal are compared for the United Kingdom, France, Sweden and Canada. The disparity between scientifically assessed and publicly perceived levels of risk is noted. The author argues that the form of decision-making process is more important to public acceptance of radioactive waste disposal than the technology of disposal. Public risk perception can be altered by procedures employed in planning, negotiation and consultation. Precisely what constitutes acceptable risk does vary from country to country, and differences in institutional responses and innovation are particularly highlighted. (UK)

    2018-03-01

    After cold shock, the Bacillus subtilis desaturase Des introduces double bonds into the fatty acids of existing membrane phospholipids. The synthesis of Des is regulated exclusively by the two-component system DesK/DesR; DesK serves as a sensor of the state of the membrane and triggers Des synthesis after a decrease in membrane fluidity. The aim of our work is to investigate the biophysical changes in the membrane that are able to affect the DesK signalling state. Using linear alcohols (ethanol, propanol, butanol, hexanol, octanol) and benzyl alcohol, we were able to suppress Des synthesis after a temperature downshift. The changes in the biophysical properties of the membrane caused by alcohol addition were followed using membrane fluorescent probes and differential scanning calorimetry. We found that the membrane fluidization induced by alcohols was reflected in an increased hydration at the lipid-water interface. This is associated with a decrease in DesK activity. The addition of alcohol mimics a temperature increase, which can be measured isothermically by fluorescence anisotropy. The effect of alcohols on the membrane periphery is in line with the concept of the mechanism by which two hydrophilic motifs located at opposite ends of the transmembrane region of DesK, which work as a molecular caliper, sense temperature-dependent variations in membrane properties.

    Les activites humaines energivores telles l'utilisation intensive de l'automobile, la surconsommation de biens et l'usage excessif d'electricite contribuent aux changements climatiques et autres problemes environnementaux. Bien que plusieurs recherches rapportent que l'etre humain est de plus en plus conscient de ses impacts sur le climat de la planete, ces memes recherches indiquent qu'en general, les gens continuent a se comporter de facon non ecologique. Que ce soit a l'ecole ou dans la communaute, plusieurs chercheurs en education relative a l'environnement estiment qu'une personne bien intentionnee est capable d'adopter des comportements plus respectueux de l'environnement. Le but de cette these etait de comprendre le processus d'integration de comportements d'attenuation des changements climatiques dans des familles. A cette fin, nous nous sommes fixe deux objectifs : 1) decrire les competences et les procedes qui favorisent l'adoption de comportements d'attenuation des changements climatiques dans des familles et 2) decrire les facteurs et les dynamiques familiales qui facilitent et limitent l'adoption de comportements d'attenuation des changements climatiques dans des familles.

    Carbon Dioxide Capture and Storage (CCS) is assumed to be one of the key technologies in the mitigation of climate change. Public acceptance may have a strong impact on the progress of this technology. Benefit perception and risk perception are known to be important determinants of public acceptance of CCS. In this study, the prevalence and effect of cognitive concepts underlying laypeople's risk perception and benefit perception of CCS were examined in a representative survey (N=654) in Switzerland. Results confirm findings from previous qualitative studies and show a quantification of a variety of widespread intuitive concepts that laypeople hold about storage mechanisms as well as about leakage and socioeconomic issues, which all appeared to influence risk perception and benefit perception. The perception of an overpressurized reservoir and concerns about diffuse impacts furthermore amplified risk perception. Appropriate images about storage mechanisms and climate change awareness were increasing the perception of benefits. Knowledge about CO2 seemed to lower both perceived benefits and perceived risks. Implications for risk communication and management are discussed.

    Full Text Available Abstract Background The Mexico-U.S. border region is experiencing rising rates of blood-borne infections among injection drug users (IDUs, emphasizing the need for harm reduction interventions. Methods We assessed the religious and cultural factors affecting the acceptability and feasibility of three harm reduction interventions – Needle exchange programs (NEPs, syringe vending machines, and safer injection facilities (SIFs – in Tijuana, Mexico. In-depth qualitative interviews were conducted with 40 community stakeholders to explore cultural and societal-related themes. Results Themes that emerged included Tijuana's location as a border city, family values, and culture as a mediator of social stigma and empathy towards IDUs. Perception of low levels of both awareness and socio-cultural readiness for harm reduction interventions was noted. Religious culture emerged as a theme, highlighting the important role religious leaders play in determining community responses to harm reduction and rehabilitation strategies for IDUs. The influence of religious culture on stakeholders' opinions concerning harm reduction interventions was evidenced by discussions of family and social values, stigma, and resulting policies. Conclusion Religion and politics were described as both a perceived benefit and deterrent, highlighting the need to further explore the overall influences of culture on the acceptability and implementation of harm reduction programs for drug users.

    2014-01-01

    Development of unconventional fossil fuels is generating controversy in North America, where citizen support or opposition can shape political decisions. This study explores the role of values in citizen perceptions. The case study is Canada's proposed Northern Gateway Pipeline (NGP), which would transport bitumen from Alberta's oil sands to British Columbia's (BC) northern coast for export. Data were collected in 2013 from a sample of Canadian citizens (n=2628). The survey instrument elicited citizen perceptions of the NGP, as well as values and attitudes. Respondents in the Alberta subsample are the most likely to support the NGP and to perceive economic benefits. Respondents in the BC subsample are the most likely to oppose the NGP and to perceive environmental risks. To explore heterogeneity in motivations among both subsamples, respondent clusters are constructed based on values. In both regions, opposition is highest in clusters with strong biospheric–altruistic values, while acceptance is highest in clusters with strong traditional values. Regional effects are also substantial; NGP acceptance is higher in each of Alberta's clusters relative to equivalent clusters in BC. Regional context seems to shape how values correspond with perceptions. Insights are drawn for energy project development, public consultation and energy planning. - Highlights: • Acceptance of the proposed Northern Gateway Pipeline (NGP) varies by region. • Regional variations in perceptions correspond with differing risks and benefits. • Opposition is highest among citizens with strong biospheric–altruistic values. • Acceptance is highest for citizens with strong traditional or egoistic values. • Values may shape citizen perceptions of economic benefits and environmental risks

    Diseases of the mandible affect the soft tissues aside from the osseous manifestation. This can be shown clearly and in great detail by magnetic resonance imaging (MRI). MRI is the gold standard in the diagnostic evaluation of any internal derangement of the temporomandibular joint. Dental MRI requires high resolution techniques and in some cases also intravenous administration of contrast material. These techniques allow delineation of the neurovascular bundle. In the past few years new indications were formulated, for example, the evaluation of the integrity of the inferior alveolar nerve in trauma and in radicular cysts. New quantitative methods now enable insights into the pathophysiology. The objective of this review is to communicate accepted indications for MRI of the mandible and to present innovative applications. (orig.) [German] Mandibulaere Erkrankungen beteiligen neben dem Knochen Weichteilstrukturen, die sich mit der MRT klar und detailreich darstellen lassen. In der bildgebenden Diagnostik der Binnenstoerung des Kiefergelenks (internal derangement) gilt die MRT als Goldstandard. Die MR-Tomographie des Unterkiefers erfordert hochaufloesende Techniken und bei besonderen Indikationen die intravenoese Kontrastmittelgabe. Diese Techniken erlauben es, das neurovaskulaere Buendel des Unterkiefers darzustellen. In den letzten Jahren sind neue Indikationsgebiete hinzugekommen, darunter solche, die die Unversehrtheit des N.alveolaris inferior bei Frakturen oder Raumforderungen des Unterkiefers ueberpruefen. Neue quantitative Verfahren geben mittlerweile Einblicke in Pathophysiologie.

    An implicit assumption of risk perception studies is that concerns expressed in questionnaires reflect concerns in everyday life. The aim of the present study is to check this assumption, i.e., the extrapolability of risk perceptions expressed in a survey, to risk perceptions in everyday life. To that end, risk perceptions were measured by a multidimensional approach. In addition to the traditional focus on measuring the magnitude of risk perceptions, the thematic relevance (how often people think about a risk issue) and the discursive relevance (how often people think about or discuss a risk issue) of risk perceptions were also collected. Taking into account this extended view of risk perception, an online survey was conducted in six European countries with 2454 respondents, referring to radio frequency electromagnetic field (RF EMF) risk potentials from base stations, and access points, such as WiFi routers and cell phones. The findings reveal that the present study's multidimensional approach to measuring risk perception provides a more differentiated understanding of RF EMF risk perception. High levels of concerns expressed in questionnaires do not automatically imply that these concerns are thematically relevant in everyday life. We use thematic relevance to distinguish between enduringly concerned (high concern according to both questionnaire and thematic relevance) and not enduringly concerned participants (high concern according to questionnaire but no thematic relevance). Furthermore, we provide data for the empirical value of this distinction: Compared to other participants, enduringly concerned subjects consider radio frequency electromagnetic field exposure to a greater extent as a moral and affective issue. They also see themselves as highly exposed to radio frequency electromagnetic fields. However, despite these differences, subjects with high levels of thematic relevance are nevertheless sensitive to exposure reduction as a means for improving the

    Background: The Arab adult with T2DM is understudied with less known facts about the perception of empowerment and its relationship with self-care and glycemic control. Purpose: The purpose of this study was to determine the extent to which perception of empowerment by Arab adults living with Type 2 Diabetes Mellitus (T2DM) was associated with better glycemic control and self-care management. Methods: A cross-sectional descriptive study was led among 300 Arab adults living in Oman with T2DM in an outpatient diabetes clinic. The Diabetes Empowerment Scale (DES), glycosylated haemaglobin (HbA1c) and Body mass index was assessed. The DES was found to be valid and reliable for the population. ANOVA, Regression analysis, and Structural equation modeling was used for analysis. Results: The composite score and three subscales of DES were a significant and strong predictor of good glycemic control among Omani adults with T2DM (pempowerment and tailor interventions to increase empowerment for better glycemic control.

Les traits observables les plus saillants sont ceux de la morphologie graphique, mais il n’en reste pas moins que certains jeunes utilisent des lexiques particuliers dans les blogs qui méritent une attention particulière. Nous nous proposons donc d’étudier les différents lexiques utilisés par des jeunes de 12 à 22 ans dans les blogs de la plateforme skyrock.com aux niveaux de sa diversité, de ses usages sémantiques variable d’un scripteur à l’autre pour un même mot, et de ses particularités morphosyntaxiques. En effet, nous observerons des lexiques divers allant des lexiques perçus comme relevant des cités à des lexiques perçus comme étant « branchés-jeunes », ou encore à des lexiques propres aux supports modernes de communication. Ainsi, nous analyserons des lexiques variés dans leurs usages écrits tels que bolos, bédave, gérer, ouf, tigen, ou encore des lexiques empruntés tels que mouv, full, etc., ainsi que des emplois particuliers de séquences autonomes comme lol. Quelques questions périphériques complèteront notre analyse telle que celles qui concerne l’influence des usages lexicaux entre pairs et le savoir partagé, la distinction de différentes communautés en fonction des lexiques utilisés, ou encore la variabilité des représentations graphiques d’un même mot.

    Purpose To produce a physician and scientific workforce capable of delivering high quality, culturally competent health care and research, academic medical centers must assess their capacity for diversity and inclusion and respond to identified opportunities. Thus, the Diversity Engagement Survey (DES) is presented as a diagnostic and benchmarking tool. Method The 22-item DES connects workforce engagement theory with inclusion and diversity constructs. Face and content validity were established based on decades of previous work to promote institutional diversity. The survey was pilot tested at a single academic medical center and subsequently administered at 13 additional academic medical centers. Cronbach alphas assessed internal consistency and Confirmatory Factor Analysis (CFA) established construct validity. Criterion validity was assessed by observed separation in scores for groups traditionally recognized to have less workforce engagement. Results The sample consisted of 13,694 individuals at 14 medical schools from across the U.S. who responded to the survey administered between 2011– 2012. The Cronbach alphas for inclusion and engagement factors (range: 0.68 to 0.85), CFA fit indices, and item correlations with latent constructs, indicated an acceptable model fit and that questions measured the intended concepts. DES scores clearly distinguished higher and lower performing institutions. The DES detected important disparities for black, women, and those who did not have heterosexual orientation. Conclusions This study demonstrated that the DES is a reliable and valid instrument for internal assessment and evaluation or external benchmarking of institutional progress in building inclusion and engagement.

    2013-02-01

    Major nuclear accidents, such as the recent accident in Fukushima, Japan, have been shown to decrease the public's acceptance of nuclear power. However, little is known about how a serious accident affects people's acceptance of nuclear power and the determinants of acceptance. We conducted a longitudinal study (N= 790) in Switzerland: one survey was done five months before and one directly after the accident in Fukushima. We assessed acceptance, perceived risks, perceived benefits, and trust related to nuclear power stations. In our model, we assumed that both benefit and risk perceptions determine acceptance of nuclear power. We further hypothesized that trust influences benefit and risk perceptions and that trust before a disaster relates to trust after a disaster. Results showed that the acceptance and perceptions of nuclear power as well as its trust were more negative after the accident. In our model, perceived benefits and risks determined the acceptance of nuclear power stations both before and after Fukushima. Trust had strong effects on perceived benefits and risks, at both times. People's trust before Fukushima strongly influenced their trust after the accident. In addition, perceived benefits before Fukushima correlated with perceived benefits after the accident. Thus, the nuclear accident did not seem to have changed the relations between the determinants of acceptance. Even after a severe accident, the public may still consider the benefits as relevant, and trust remains important for determining their risk and benefit perceptions. A discussion of the benefits of nuclear power seems most likely to affect the public's acceptance of nuclear power, even after a nuclear accident. © 2012 Society for Risk Analysis.

    Résumé Religion et guérisseurs traditionnels occupent encore une place prépondérante dans la prise en charge des maladies mentales à Madagascar. Ainsi, nous nous sommes fixés comme objectif d'établir un état des lieux sur les soins de premier recours des malades mentaux. Nous avons mené une étude rétrospective descriptive s'étalant sur une période de 16 mois allant de janvier 2014 en avril 2015 au sein du service de psychiatrie du CHU de Befelatanana à Antananarivo. La prévalence des psychoses était de 25%. Le genre féminin (53%), l'ethnie merina (77%), les étudiants (45%), le niveau d'étude secondaire (40%), les célibataires (72%), la religion protestante (45%), ainsi que le niveau socio-économique moyen (57,5%) étaient prédominants. Dans les paramètres cliniques, le mode de début brutal (52%), le premier recours à la religion (40%), la présence d'antécédents des cas similaire (90%), étaient majoritaires. La schizophrénie était la pathologie la plus rencontrée dans la moitié des cas. Le délai d'amélioration en cas de traitement religieux et traditionnels était dans la moitié des cas de plus de 10 jours d'hospitalisation. Les patients ayant reçu une prise en charge psychiatrique en premier recours, étaient améliorés dans 75 % cas en moins de 10jours. Le retard du recours aux soins psychiatriques est une réalité à Madagascar qui aggrave le pronostic des psychoses. PMID:29632623

    2013-07-01

    Full Text Available La diversification des cultures est souvent présentée comme un levier d’action pour accroître la durabilité des systèmes de production agricoles. Bien raisonnée, elle favorise en effet une réduction de l’usage d’intrants extérieurs à l’exploitation – pesticides, engrais, eau – et des nuisances environnementales associées à leur utilisation excessive. À l’inverse, la simplification des systèmes de culture engagée depuis plus de 40 ans s’est accompagnée d’un recours croissant aux intrants. Cependant, malgré son intérêt pour les systèmes de production en termes de durabilité écologique mais aussi économique (répartition des risques, et son inscription dans divers plans et dispositifs incitatifs, la diversification des cultures progresse peu. Les ministères en charge de l’agriculture et de l’environnement ont donc commandé à l’INRA une étude visant à identifier les freins à la diversification des cultures en France et les leviers mobilisables, par les pouvoirs publics notamment, pour la favoriser. L’hypothèse de travail est que ces freins relèvent du fonctionnement global du système agro-industriel, et de la capacité de développement de filières valorisant les cultures de diversification. L’étude a examiné un certain nombre de cas représentatifs de la diversité des filières et notamment de leurs modes d’organisation, qui déterminent la coordination et l’engagement des acteurs économiques impliqués dans le développement d’une culture de diversification.

En un quart de siècle, l’amélioration génétique aura suffisamment fait de progrès pour escompter un gain de production de l’ordre de 20%. Enfin, dans certaines situations, plusieurs maladies ont pu affecter les vieilles palmeraies. Avec de 15 à 25% d’arbres manquants, principalement lorsque ceux-ci se présentent sous la forme de taches, une diminution de la production se fait nettement sentir. Cela peut, par exemple, être le cas avec les maladies de la fusariose en Afrique de l’Ouest, lorsque la palmeraie n’a pas été plantée avec du matériel végétal tolérant, ou du ganoderma en Malaisie. Le renouvellement des cocoteraies se fait avec un espace de temps beaucoup plus long. En effet, la récolte des noix peut se faire au sol et la hauteur des cocotiers n’est donc pas un facteur limitant. Par ailleurs, la majorité des cocoteraies étant sous la forme de petites plantations villageoises, les agriculteurs rechignent toujours à abattre leurs cocotiers, même si des semences potentiellement plus productives leurs sont proposées. Ce sont les raisons pour lesquelles les cocoteraies de 50 ans et plus représentent la règle. L’abattage d’une plantation de palmiers à huile ou de cocotiers constitue naturellement un changement brutal de l’environnement, ce qui a des conséquences importantes notamment sur l’entomofaune, parmi laquelle des ravageurs majeurs ainsi que leurs ennemis naturels.

    2013-07-01

    Full Text Available E-prescribing systems hold promise for improving the quality and efficiency of the scripting process. Yet, the use of the technology has been associated with a number of challenges. The diffusion of e-prescribing into physician practices and the consequent realisation of its potential benefits will depend on whether physicians are willing to accept and engage with the technology. This study draws on the Unified Theory of Acceptance and Use of Technology (UTAUT and recent literature on user trust in technology to develop and test a model of the factors influencing South African physicians’ acceptance of e-prescribing. Data was collected from a sample of 72 physicians. Results indicate a general acceptance of e-prescribing amongst physicians who on average reported strong intentions to use e-prescribing technologies if given the opportunity. PLS analysis revealed that physicians’ performance expectancies and perceptions of facilitating conditions had significant direct effects on acceptance whilst trust and effort expectancy had important indirect effects. Social influence and price value perceptions did not add additional explanatory power. The model explained 63% of the variation in physician acceptance.

    2007-04-01

    Cognitive-behavioral therapy (CBT) and pharmacotherapy are the most well-established treatments for childhood anxiety disorders. This study examined how parents (N=71) seeking treatment for their child's anxiety disorder perceive the acceptability, believability, and effectiveness of these treatments. While both treatments were perceived favorably, CBT was rated as more acceptable, believable, and effective in the short- and long-term. Children's treatment history influenced parents' perceptions of pharmacotherapy, with parents of children with no treatment history perceiving medication treatment as less acceptable and believable than parents of children with a history of medication alone or in combination with behavior therapy. No effect of treatment history was found for perceptions of CBT. Significant positive correlations emerged between parents' perceived acceptance and believability for pharmacotherapy and child age and level of dysfunction due to their child's anxiety, respectively. The level of the child's anxiety was not significantly correlated with parents' perceptions of either CBT or pharmacotherapy. Our results suggest that parents of anxious children prefer CBT to medication for the treatment of their child's anxiety disorder. Directions for future research are discussed.

  12. Dynamique de nanobulles et nanoplasmas generes autour de nanoparticules plasmoniques irradiees par des impulsions ultracourtes

    Science.gov (United States)

    Dagallier, Adrien

    L'emergence des lasers a impulsion ultrabreves et des nanotechnologies a revolutionne notre perception et notre maniere d'interagir avec l'infiniment petit. Les gigantesques intensites generees par ces impulsions plus courtes que les temps de relaxation ou de diffusion du milieu irradie induisent de nombreux phenomenes non-lineaires, du doublement de frequence a l'ablation, dans des volumes de dimension caracteristique de l'ordre de la longueur d'onde du laser. En biologie et en medecine, ces phenomenes sont utilises a des fins d'imagerie multiphotonique ou pour detruire des tissus vivants. L'introduction de nanoparticules plasmoniques, qui concentrent le champ electromagnetique incident dans des regions de dimensions nanometriques, jusqu'a une fraction de la longueur d'onde, amplifie les phenomenes non-lineaires tout en offrant un controle beaucoup plus precis de la deposition d'energie, ouvrant la voie a la detection de molecules individuelles en solution et a la nanochirurgie. La nanochirurgie repose principalement sur la formation d'une bulle de vapeur a proximite d'une membrane cellulaire. Cette bulle de vapeur perce la membrane de maniere irreversible,entrainant la cellule a sa mort, ou la perturbe temporairement, ce qui permet d'envisager de faire penetrer dans la cellule des medicaments ou des brins d'ADN pour de la therapie genique. C'est principalement la taille de la bulle qui va decider de l'issue de l'irradiation laser. Il est donc necessaire de controler finement les parametres du laser et la geometrie de la nanoparticule afin d'atteindre l'objectif fixe. Le moyen le plus direct a l'heure actuelle de valider un ensemble de conditions experimentales est de realiser l'experience en laboratoire,ce qui est long et couteux. Les modeles de dynamique de bulle existants ne prennent pas en compte les parametres de l'irradiation et ajustent souvent leurs conditions initiales a partir de leurs mesures experimentales, ce qui limite la portee du modele au cas pour

    The not-in-my-backyard (NIMBY) syndrome has long been the focus of academic and policy research. We test several competing hypothesis concerning the sources of NIMBY sentiments, including demographics, proximity, political ideology and partisanship, and the unfolding policy process over time. To test these hypotheses we use survey data collected in New Mexico dealing with risk perceptions and acceptance related to the Waste Isolation Pilot Project (WIPP), a permanent storage site for radioactive waste located near Carlsbad, New Mexico. WIPP became operational and received its first shipment of waste on March 26, 1999. This study tracks the changes of risk perception and acceptance over a decade, using measures taken from 35 statewide surveys of New Mexico citizens spanning the 11-year period from fall 1990 to summer 2001. This time span includes periods before and after WIPP became operational. We find that acceptance of WIPP is greater among those in the most proximate counties to WIPP. Surprisingly, and contrary to expectations drawn from the broader literature, acceptance is also greater among those who live closest to the nuclear waste transportation route. We also find that ideology, partisanship, government approval and broader environmental concerns influence support for WIPP acceptance. Finally, the sequence of procedural steps taken toward formal approval of WIPP by government agencies proved to be important to public acceptance, the most significant being the opening of the WIPP facility itself

Customer perceptions about usage based pricing were collected using a structured questionnaire. The model containing critical variables was validated to identify statistically significant linkages among perceived individual benefits, perceived social benefits, perceived value, perceived easiness to understand and acceptance intentions. The perceived risk to privacy was not found to influence the acceptance intentions of the customer. The study concluded that customers are likely to accept the concept of usage based pricing once implemented.

  4. Waste transmutation and public acceptance

    International Nuclear Information System (INIS)

    Pigford, T.H.

    1991-01-01

    The concept of transmuting radioactive wastes with reactors or accelerators is appealing. It has the potential of simplifying or eliminating problems of disposing of nuclear waste. The transmutation concept has been renewed vigorously at a time when national projects to dispose of high-level and transuranic waste are seriously delayed. In this period of tightening federal funds and program curtailments, skilled technical staffs are available at US Department of Energy (DOE) national laboratories and contractors to work on waste transmutation. If the claims of transmutation can be shown to be realistic, economically feasible, and capable of being implemented within the US institutional infrastructure, public acceptance of nuclear waste disposal may be enhanced. If the claims for transmutation are not substantiated, however, there will result a serious loss of credibility and an unjust exacerbation of public concerns about nuclear waste. The paper discusses the following topics: how public acceptance is achieved; the technical community and waste disposal; transmutation and technical communication; transmutation issues; technical fixes and public perception

Externalities issues, which are problems characterized by their public nature, have to be defined and sized at different levels: besides the global one (which concerns debates on global public goods and the local one (how sustainable are private activities, collective and territorial levels are also necessary to set up socially acceptable responses.

    The aim of the study was to determine temporal orientation in patients diagnosed with RR-MS as compared with that of healthy individuals; to analyse self-evaluated acceptance levels in terms of physical and psychological condition and self-reliance; an attempt to identify factors of illness acceptance in patients with RR-MS including temporal perspective. Acceptance of Illness Scale (AIS, adapted into Polish by Z. Juczyński), Zimbardo Time Perspective Inventory (ZTPI, adapted into Polish by M. Mażewski), and original interview aimed to assess socio-demographic data and self-evaluated physical as well as psychological condition and self-reliance of patients with MS (referred to the neurological testing according to the EDSS). Patients with RR-MS focus on fatalistic and hedonistic present more than healthy individuals. They also tend to reflect on their negative past experience. Acceptance of illness correlated positively with subjective assessment of physical and psychological condition as well as self-reliance, and negatively with objective disability score (measured with the use of EDSS) and a factor considering time of disease duration. Avoiding contemplation of negative past and concentrating on hedonistic future constitute significant predictors of illness acceptance. These results may be of importance in terms of holistic approach to treatment of RR-MS patients. In the initial stage of the disease progression, patients might benefit from psychological support due to change in temporal orientation.

    2016-01-01

    Full Text Available Drivers’ risk perception is vital to driving behavior and traffic safety. In the dynamic interaction of a driver-vehicle-environment system, drivers’ risk perception changes dynamically. This study focused on drivers’ risk perception at unsignalized intersections in China and analyzed drivers’ crossing behavior. Based on cognitive psychology theory and an adaptive neuro-fuzzy inference system, quantitative models of drivers’ risk perception were established for the crossing processes between two straight-moving vehicles from the orthogonal direction. The acceptable risk perception levels of drivers were identified using a self-developed data analysis method. Based on game theory, the relationship among the quantitative value of drivers’ risk perception, acceptable risk perception level, and vehicle motion state was analyzed. The models of drivers’ crossing behavior were then established. Finally, the behavior models were validated using data collected from real-world vehicle movements and driver decisions. The results showed that the developed behavior models had both high accuracy and good applicability. This study would provide theoretical and algorithmic references for the microscopic simulation and active safety control system of vehicles.

  1. The outcomes and acceptability of near-peer teaching among medical students in clinical skills.

    2016-06-12

    To determine the outcomes and acceptability of final-year students tutoring in Clinical Skills to Years 1-2 students in a 4-week Medical Education elective. A paper-based survey with 14 questions requiring responses on a Likert-like scale and 2 questions with free-text responses was used to investigate Year 6 student-tutor (n=45) and Years 1-2 tutee (n=348) perceptions of near-peer teaching in Clinical Skills. The independent t-test compared mean responses from student-tutors and tutees, and thematic analysis of free-text responses was conducted. Tutee perceptions were significantly higher than student-tutor self-perceptions in small-group teaching and facilitation skills (p=0.000), teaching history-taking skills (p=0.046) and teaching physical examination skills (p=0.000). Perceptions in aspects of 'Confidence in tutoring' were not significantly different for student-tutors and tutees, with both having lowest perceptions for identifying and providing remediation for underperforming tutees. Student-tutors rated all areas of personal and professional development highly. Main themes emerging from analysis of student comments were the benefits to student-tutors, benefits to tutees and areas needing improvement, with outcomes of this near-peer teaching relating well to cognitive and social theories in the literature. Both student tutors and their tutees perceived near-peer teaching in Clinical Skills to be acceptable and beneficial with particular implications for Medical Education.

    The acceptability of nanomedical applications, which have the potential to generate ethical and societal impacts, is a significant factor in the deployment of nanomedicine. A lack of fit between nanomedical applications and society’s values may result from a partial consideration of such impacts. New approaches for technological evaluation focused on impact perception, acceptance, and acceptability are needed to go beyond traditional technology assessment approaches used with nanotechnology, which focus mainly on toxicological and safety criteria. Using a new evaluative approach based on perceived impacts of nanotechnology, the objective of this study was to assess perceptions among researchers and research trainees familiar with emergent technologies and from different disciplinary background the scope of acceptability judgments made towards the use of nanocarriers. This mixed-methods study was based on scenarios presenting two types of drug-delivery nanocarriers (carbon, synthetic DNA) in two contexts of use (lung cancer treatment, seasonal flu treatment). Researchers and research trainees in the natural sciences and engineering, and the social sciences and the humanities were invited by email to take part in this project. An online questionnaire followed by semi-directed interviews allowed characterization of disciplinary divergences regarding to impact perception, acceptance, and acceptability of the scenarios. The results suggest that impact perception is influenced by disciplinary culture. Also, trends can be seen between respondents’ profiles and variables of acceptance and acceptability, and certain components of the acceptability judgement are specific to each disciplinary culture. The acknowledgment and consideration of these disciplinary divergences could allow, among others, for opening up interdisciplinary dialogue on matters related to the acceptability of nanomedical applications and their developments

    The relationship between instrumental colorimetric values (L*, a*, b*, the ratio of reflectance at 630nm and 580nm) and consumer perception of acceptable beef colour was evaluated using a web-based survey and standardised photographs of beef m. longissimus lumborum with known colorimetrics. Only L* and b* were found to relate to average consumer opinions of beef colour acceptability. Respondent nationality was also identified as a source of variation in beef colour acceptability score. Although this is a preliminary study with the findings necessitating additional investigation, these results suggest L* and b* as candidates for developing instrumental thresholds for consumer beef colour expectations.

    Milhabet, I; Verlhiac, J F

    2011-10-01

    Studies of optimism and realism (the accuracy of people's outlook on the future) seek to understand the respective effects of these elements on social approbation. Two experiments examined how comparative optimism (vs. pessimism) and realism (vs. unrealism) interacted to influence the targets' social acceptance based on their perceptions about the future. The results showed that realism, or accuracy of prediction, increased the positive social effects of a comparatively optimistic outlook on the future. In contrast, targets who exhibited comparative pessimism were more socially acceptable when their predictions were unrealistic rather than realistic. This phenomenon was examined by also considering the polarity of the events about which judgments were expressed. These results contribute to the body of research about the relationship between optimism and pessimism and the relationship between optimism and realism.

Le prisme des méthodes de « relations humaines » pour la gestion des salariés est ici utilisé pour rendre compte des modes de construction d’une identité professionnelle prise entre l’« esprit du religieux » et l’« esprit du capitalisme ». La déclinaison des « relations humaines » en fonction du projet de justice sociale préconisé par la doctrine sociale de l’Église en ressort amendée, car elles sont perçues moins comme un levier pour l’intégration des salariés que comme un instrument au service du contrôle politique de ceux-ci.Are the relations more human?

    Full Text Available BACKGROUND: Within the past 10 years, cognitive-behavioural pain management models have moved beyond the traditional focus on coping strategies and perceived control over pain, to incorporate mindfulness-and acceptance-based approaches. Pain acceptance is the process of giving up the struggle with pain and learning to live life despite pain. Acceptance is associated with lower levels of pain, disability and psychological distress. Relatively little is known, however, about how patients arrive at a state of acceptance without the aid of therapy.

    2011-09-30

    Physical activity (PA) during childhood often occurs in social contexts. As such, children's ability to develop and maintain friendship groups may be important in understanding their PA. This paper investigates the associations among children's social functioning, and physical activity and whether perceptions of social acceptance mediate any social functioning-PA association. A cross sectional survey in which 652 10-11 year olds self-reported their peer (e.g. difficulties with friends) and conduct (e.g. anger/aggression) problems, prosocial behaviours (e.g. being kind to others) and perceptions of social acceptance. Physical activity was objectively assessed by Actigraph GT1M accelerometers to estimate counts per minute, (CPM) and minutes of moderate-to-vigorous physical activity (MVPA). Linear regression analyses were conducted to investigate associations between social functioning and PA. Indirect effects were analysed to explore mediation by social acceptance. Among boys, peer problems were negatively associated with CPM and MVPA and conduct problems were positively associated with CPM and MVPA. Prosocial behaviour was unrelated to PA in boys. Social functioning was not associated with PA among girls. Social acceptance did not mediate the social functioning-PA relationship. Boys' conduct and peer problems were associated positively and negatively respectively with their PA but this relationship was not mediated by perceptions of social acceptance. Future research should study alternative mediators to understand the processes underpinning this relationship.

La deuxieme partie est consacree a l'etude des proprietes magnetiques et de transport des multicouches ferromagnetiques/ferromagnetiques Ni/Fe. Nous montrerons qu'une interpretation coherente de ces proprietes necessite la prise en consideration des effets des interfaces. Nous nous attacherons a mettre en evidence, a evaluer et a etudier les effets de ces interfaces ainsi que leur evolution, et ce, suite a des traitements thermiques tel que le depot a temperature elevee et l'irradiation ionique. Les analyses correlees de la structure et de la magnetoresistance nous permettront d'emettre des conclusions sur l'influence des couches tampons entre l'interface et le substrat ainsi qu'entre les couches elles-memes sur le comportement magnetique des couches F/F. La troisieme partie est consacree aux systemes a Magneto-Resistance Geante (MRG) a base de Co et Ag. Nous allons etudier l'evolution de la microstructure suite a l'irradiation avec des ions Si+ ayant une energie de 1 MeV, ainsi que les effets de ces changements sur le comportement magnetique. Cette partie debutera par l'analyse des proprietes d'une multicouche hybride, intermediaire entre les multicouches et les materiaux granulaires. Nous analyserons a l'aide des mesures de diffraction, de relaxation superparamagnetique et de magnetoresistance, les evolutions structurales produites par l'irradiation ionique. Nous etablirons des modeles qui nous aideront a interpreter les resultats pour une serie des multicouches qui couvrent un large eventail de differents comportements magnetiques

    Uranium processing from the pit to the fuel element rod entails metal losses at every step. These losses become more and more expensive with the elaboration of the metal. Some of the uranium must be accepted as definitely lost whilst the rest could be recovered and recycled. The high cost of these losses, whether they are recycled or not, and the fact that the higher the enrichment is the higher their costs are, make it necessary to take them into account when optimizing fuel cycles. It is therefore felt important to determine their most desirable level from an economic point of view at the various nuclear fuel processing stages. However, in France as in some other countries, fissile material production is a state concern, whilst fuel element fabrication is carried out by private enterprise. Optimization criteria and the economic value of losses are therefore different for each of the two links in the fabrication chain. One can try in spite of this to reach an optimum which would conform to public interest, without interfering with the firm's sales policy. This entails using the fact that for a given output marginal costs are equal at the optimum. One can therefore adjust the level of the losses to attain this equation of marginal costs, as these are easier to obtain from the firm than a justification of the actual prices. One notices moreover that, although mainly concerned with losses, this global analysis can bring both the state and the firm to a better use of other production factors. An account is given of the theory of this economic optimization method and practical applications in the field of natural uranium-graphite moderated and CO{sub 2} cooled reactor fuel element fabrication are offered.

    Concerns for health can lead to healthier food choices, especially if the consumer is well informed. This study aimed to evaluate the importance of package and health-related claims on Brazilian consumers' acceptance of snack bars. In order to evaluate package attributes, in focus groups discussions, 19 consumers chose the most important factors that influence their purchase decisions. Next, 102 consumers evaluated six commercial brands of snack bars in a three-session acceptance test: the first with no information about the product, the second containing the product package and the third with information on health-related claims associated with consumption of the bar. In general, package attributes, price and flavor were the most important factors that influence the purchase of snack bars. Health claims positively influenced consumer acceptance, but information concerning the absence of gluten and lactose did not significantly alter sensory acceptance. The presence of omega-3s, sugars, preservatives, flavorings and colorings have the potential to improve acceptability, because they were able to raise the acceptance of the seed bar, removing it from the rejection region. Protein and nut bars are not well known to the general public and the lower mean acceptance of the seed and protein bars demonstrated the need for sensorial improvement.

    Results of work at C.E.A. from 1958 to 1960 are reviewed. The possibilities offered by classical dosimetry methods are discussed. The tests which led to the utilization, for fast neutron dosimetry, of resistivity variations induced in solid W by such neutrons are described. Experimental W irradiation results led to a definition of neutron efficiency which describes the relations between neutron energy and their effects on materials. Possibilities offered by detectors which make use of radiation damage and are sensitive to neutrons at keV energies were explored. In other work, the principal French reactors were classified according to their ability to produce damage in materials such as W.

  19. Nuclear energy: beliefs, values, and acceptability

    Energy Technology Data Exchange (ETDEWEB)

    van der Pligt, J; Eiser, J R

    1985-06-01

    The last decade has seen a dramatic increase in public concern about nuclear energy. As a consequence, it has become recognized that the future of nuclear energy will not only depend on technical and economic factors, but that public acceptability of this technology will play a crucial role in the long-term future of nuclear energy. Research has shown a considerable divergence in public and expert assessment of the risks associated with nuclear energy. Qualitative aspects of risks play a dominant role in the public's perception of risks, and it seems necessary for experts to recognize this in order to improve relations with the general public. It is also clear, however, that differences in the perception of risks do not embrace all the relevant aspects of the public's assessment of nuclear energy. Public reaction is also related to more general beliefs and values, and the issue of nuclear energy is embedded in a much wider moral and political domain. 8 references.

  20. Perceived naturalness and evoked disgust influence acceptance of cultured meat.

    Siegrist, Michael; Sütterlin, Bernadette; Hartmann, Christina

    2018-05-01

    Cultured meat could be a more environment- and animal-friendly alternative to conventional meat. However, in addition to the technological challenges, the lack of consumer acceptance could be a major barrier to the introduction of cultured meat. Therefore, it seems wise to take into account consumer concerns at an early stage of product development. In this regard, we conducted two experiments that examined the impact of perceived naturalness and disgust on consumer acceptance of cultured meat. The results of Experiment 1 suggest the participants' low level of acceptance of cultured meat because it is perceived as unnatural. Moreover, informing participants about the production of cultured meat and its benefits has the paradoxical effect of increasing the acceptance of traditional meat. Experiment 2 shows that how cultured meat is described influences the participants' perception. Thus, it is important to explain cultured meat in a nontechnical way that emphasizes the final product, not the production method, to increase acceptance of this novel food.

    Siegrist, Michael; Visschers, Vivianne H.M.

    2013-01-01

    Utilizing a longitudinal study design, the impact of the 2011 accident in Fukushima on acceptance of nuclear power and the evaluation of several scenarios with different percentages of nuclear power were examined. Mail surveys were conducted in the German-speaking part of Switzerland. The first survey took place before the accident in Fukushima (Autumn 2010), the second survey immediately after the accident (March 2011), and the third survey half a year after the accident (October 2011). A sample of 463 persons participated in all three surveys. The accident had a negative impact on the acceptance of nuclear power. The mean change was moderate, and high correlations between the measurement points were observed. Overall, participants thus showed rather stable attitudes towards nuclear power across the three measurement waves. Results of the present study demonstrate the importance of prior beliefs and attitudes for the interpretation of an accident. The evaluation of the various scenarios was strongly influenced by participants’ pre-Fukushima attitudes towards nuclear power. - Highlights: ► Longitudinal studies are important for risk perception research. ► The accident in Fukushima had only a moderate impact on acceptance. ► Acceptance of nuclear power before and after Fukushima was highly correlated. ► People have stable attitudes towards nuclear power

    Depression and social anxiety symptoms and disorders are highly comorbid, and are associated with low social acceptance and academic competence. Theoretical models of both depression and social anxiety highlight the saliency of negative self-perceptions. We examined whether children's self-perceptions of social acceptance and mother-reported youth social acceptance are independently and uniquely related to children's depression and social anxiety, both before and after controlling for comorbid symptoms. Similar questions were examined regarding academic competence. The sample was 110 clinic-referred youth aged 8-16 years (65 boys, 45 girls; M age = 11.15, SD = 2.57). In the social acceptance area, both youth self-perceptions and mother-perceptions had independent and unique relations to depression and social anxiety, before and after controlling for comorbid symptoms. In the academic domain, both youth self-perceptions and mother-perceptions had independent and unique relations to depression, before and after controlling for social anxiety; yet only youth self-perceptions were related to social anxiety, before, but not after controlling for depression. For depression, larger effect sizes were observed for children's perceived, versus mother-reported, social acceptance and academic competence. Bootstrapping and Sobel tests found youth self-perceptions of social acceptance mediated the relation between mothers' perceptions and each of youth depression and social anxiety; and perceived academic competence mediated the relation between mothers' perceptions and youth depression, both before and after controlling for social anxiety. We found similarities and differences in findings for depression and social anxiety. Theoretical and treatment implications are highlighted, and future research directions are discussed.

    The eight-item Brief Illness Perception Questionnaire is used as a screening instrument in physical therapy to assess mental defeat in patients with acute low back pain, besides patient perception might determine the course and risk for chronic low back pain. However, the psychometric properties of the Brief Illness Perception Questionnaire in common musculoskeletal disorders like acute low back pain have not been adequately studied. Patients' perceptions vary across different populations and affect coping styles. Thus, our aim was to determine the internal consistency, test-retest reliability and validity of the Dutch language version of the Brief Illness Perception Questionnaire in acute non-specific low back pain patients in primary care physical therapy. A non-experimental cross-sectional study with two measurements was performed. Eighty-four acute low back pain patients, in multidisciplinary health care center in Dutch primary care with a sample mean (SD) age of 42 (12) years, participated in the study. Internal consistency (Cronbach's α) and test-retest procedures (Intraclass Correlation Coefficients and limits of agreement) were evaluated at a one-week interval. The concurrent validity of the Brief Illness Perception Questionnaire was examined by using the Mental Health Component of the Short Form 36 Health Survey. The Cronbach's α for internal consistency was 0.73 (95% CI, 0.67 - 0.83); and the Intraclass Correlation Coefficient test-retest reliability was acceptable: 0.72 (95% CI, 0.53 - 0.82), however, the limits of agreement were large. The Intraclass Correlation Coefficient measuring concurrent validity 0.65 (95% CI, 0.46 - 0.80). The Dutch version of the Brief Illness Perception Questionnaire is an appropriate instrument for measuring patients' perceptions in acute low back pain patients, showing acceptable internal consistency and reliability. Concurrent validity is adequate, however, the instrument may be unsuitable for detecting changes in low

    The nature of collective perception of prostitution is understudied in Canada. Except some rudimentary reports on the percentages of the key legal options, multivariate analysis has never been used to analyze the details of public opinion on prostitution. The current study explores the trend of public attitude toward prostitution acceptability in Canada over a 25-year span and examines the social determinants of the acceptability of prostitution, using structural equation modeling (SEM), which allows researchers to elaborate both direct and indirect effects (through mediating variables) on the outcome variable. Results show that the public has become more acceptant of prostitution over time. In addition, the less religious, less authoritarian, and more educated are more acceptant of prostitution than the more religious, more authoritarian, and less well educated. The effects of religiosity and authoritarianism mediate out the direct effects of age, gender, gender equality, marriage, marriage as an outdated institution, Quebec, race, and tolerance. The findings may serve as a reference point for the law reform regarding the regulation of prostitution in Canada.

    The needs in uranium constantly increased inciting to develop new chemical processes for the treatment of uranium ores. we searched processes that permit to get this element from ores poor in uranium, to a reasonable cost price. We used a sulphuric attack and a precipitation of uranium as phosphate uranate or pyrophosphate uranate to separate its from the different impurities. The process permitted to process ores contents of about 0,05% of uranium and to get an end product of sodium carbonate uranate containing 60 to 65% of uranium, with an acceptable cost price and an extraction yield situated between 90 and 95%. (M.B.) [French] Les besoins sans cesse accrus en uranium ont incite de developper de nouveaux procedes chimiques pour le traitement de minerais uranifere. nous avons recherche des procedes qui permettent d'obtenir cet element a partir de minerais pauvres en uranium, a un prix de revient raisonnable.

    Full Text Available Cette étude évalue l’impact de l’utilisation des sous-produits agroalimentaires dans l’alimentation des poissons d’élevage en Côte d’Ivoire. Une enquête a été réalisée en 2013 dans quinze principales zones piscicoles sur les caractéristiques technico-économiques des fermes, le profil socio-économique des promoteurs et les pratiques aquacoles, particulièrement l’alimentation des poissons. Les résultats révèlent que 71 % des pisciculteurs enquêtés utilisent des sous-produits agricoles durant au moins un stade de production. Parmi eux, 53 % utilisent exclusivement des sous-produits. Le son de riz (52 % et le mélange de sons de riz et de maïs (28 % sont les plus utilisés. Les prix moyens de ces sous-produits varient entre 20 et 105 FCFA/kg. Oreochromis niloticus et Heterotis niloticus sont les principales espèces élevées en polyculture sur les fermes. Les sous-produits sont utilisés en système semi-intensif, extensif et en rizipisciculture, en majorité en zone rurale. Les pisciculteurs sont pour la plupart des agriculteurs, âgés de plus de 40 ans. Les taux d’utilisation des sous-produits sont plus élevés dans les régions de l’Ouest, du Centre-Ouest et du Sud-Ouest de la Côte d’Ivoire, par rapport à celles du Sud et de l’Est. Les rendements des fermes sont relativement faibles (544 à 2445 kg/ha/an, avec des gains moyens quotidiens de 0,87 et 9,97 g/j pour le tilapia et l’heterotis respectivement. L’analyse des stratégies des acteurs suggère la nécessité de définir des mécanismes d’accompagnement et de financement de la pisciculture, afin que ces acteurs puissent améliorer les formulations alimentaires à partir des matières premières locales et accessibles.

  6. Perspectives on the Chaine Des Puys and Limagne Fault UNESCO World Heritage Project

    2015-04-01

    The Chaîne des Puys and Limagne fault project is acknowledged to have Outstanding Universal Value (38th session of the World Heritage UNESCO committee, June 2014). One ongoing challenge for the project is to consolidate the outreach, and to work with other sites to increase the public perception of Earth sciences. The Chaîne des Puys volcanic field in central France, became a celebrated mecca for 18/19th Century scientists, only once the volcanoes were 'discovered'. Beforehand they were only hills, but the ability to interpret landscape with prior knowledge allowed these early geologists to create a popular understanding of the geology. Since that time, the Chaîne des Puys has become a well-known volcanic site to a worldwide audience through textbooks, tourism, and commerce. To the 19th century geologists, the Limagne escarpment was just as fascinating, but lacking the ability to fully interpret this rift margin, the idea of a fault did not percolate down to the general public. With the advent of the current UNESCO project, it became clear that the geological link between the volcanoes and the fault could be exploited, not only to raise the profile of the volcanoes, but to create a greater awareness of the tectonics in the greater public. Not only have the volcanoes, become better known and more clearly understood than previously, but the fault has begun to emerge as a feature in public consciousness. We will demonstrate the many communication techniques at all levels that have been used in the project. We explain the rationale between creating a geological scale model that works on processes as well as landforms to raise the public awareness. The success is that we show how geological features can be made readable by the general public, something highly important for conservation of heritage, but also for risk perception. The increased education efforts of the scientists have also lead to an increase in science. The more informed and participatory the public is

    Full Text Available Prenant les déchets électriques et électroniques comme terrain d’observation, cette recherche étudie les fondements du commerce illégal de déchets dangereux des pays développés vers les PED. En effet, malgré la multiplication des législations, le problème des déchets dans les pays développés, loin d’être traité en amont, l’est en grande partie en aval par leur délocalisation dans les PED. Les deux lectures proposées, économique et institutionnelle, permettent de montrer comment les contraintes de coût de gestion des déchets dans les pays développés conjuguées à l’imperfection et à la non-application des législations conduisent à des comportements socialement irresponsables. À partir de là, l’implication des parties prenantes est suggérée comme solution pour éliminer ce type de comportements.Based on the analysis of the waste electrical and electronic equipments (WEEE, the research investigates the motivations for the illegal cross-border trade in hazardous wastes from developed countries to developing countries. Although many developed countries have implemented waste shipment regulations, they are passing the risks and costs of E-waste to developing countries. Indeed, E-waste is often sent for recycling and refurbishing in developing countries. The two-side proposed approach (i.e. economical and institutional suggests that both the cost for firms to comply with increasing regulations and the imperfect implementation of regulatory restrictions lead to socially irresponsible behaviours. An increasing and better involvement of stakeholders may be put forward as a solution.

    Full Text Available This study suggests equity of access goes beyond technological availability. Based on a larger exploratory study of the initial implementation stage of the Mexican government’s community technology centers, CTCs (“plazas comunitarias”, adult education instructors’ perceptions and diffusion practices are described as a mediating factor to understand non-access of poor adults. The theoretical perspective integrates concepts from innovation diffusion studies, while questioning the limitations of this theory in terms of understanding instructors’ practices. Thus, the relation between human agency and structure, from Giddens’ Theory of Structuration, is incorporated. Qualitative data from 16 CTCs are interpreted inductively. It is concluded that CTCs were a top-down innovation; instructors perceived and diffused CTCs in very different ways, thus limiting equity of access. These social practices stem from social actors’ routines, which institutionalized courses of action; understanding them could illuminate the complexity of the diffusion process, generally depicted in linear form. Résumé : La présente étude laisse entendre que l’équité d’accès va au delà de la disponibilité technologique. Établie sur une étude préliminaire plus large de la première étape de mise en œuvre des centres communautaires de technologie du gouvernement mexicain, les CCT (« plazas comunitarias », les perceptions des instructeurs dans le domaine de l’enseignement aux adultes et les pratiques de diffusion sont décrites comme un facteur médiateur permettant de comprendre pourquoi les adultes pauvres ne peuvent y avoir accès. La perspective théorique intègre des concepts provenant d’études sur la diffusion de l’innovation tout en questionnant les limites de cette théorie en ce qui concerne la compréhension des pratiques des instructeurs. Ainsi, la relation entre l’agence et la structure humaine, de la théorie de structuration de

    There has been an increase in non-daily smoking, alternative tobacco product and marijuana use among young adults in recent years. This study examined perceptions of health risks, addictiveness, and social acceptability of cigarettes, cigar products, smokeless tobacco, hookah, electronic cigarettes, and marijuana among young adults and correlates of such perceptions. In Spring 2013, 10,000 students at two universities in the Southeastern United States were recruited to complete an online survey (2,002 respondents), assessing personal, parental, and peer use of each product; and perceptions of health risks, addictiveness, and social acceptability of each of these products. Marijuana was the most commonly used product in the past month (19.2%), with hookah being the second most commonly used (16.4%). The least commonly used were smokeless tobacco products (2.6%) and electronic cigarettes (4.5%). There were high rates of concurrent product use, particularly among electronic cigarette users. The most positively perceived was marijuana, with hookah and electronic cigarettes being second. While tobacco use and related social factors, related positively, influenced perceptions of marijuana, marijuana use and related social factors were not associated with perceptions of any tobacco product. Conclusions/Importance: Marketing efforts to promote electronic cigarettes and hookah to be safe and socially acceptable seem to be effective, while policy changes seem to be altering perceptions of marijuana and related social norms. Research is needed to document the health risks and addictive nature of emerging tobacco products and marijuana and evaluate efforts to communicate such risks to youth.

    2009-06-01

    Full Text Available Les mutations des paysages régionaux dues aux pressions urbaines questionnent l’usage du sol. Elles interpellent à la fois des enjeux économiques, sociaux et environnementaux voire spatiaux sous-tendus par l’étalement urbain, l’accroissement des déplacements domicile-travail, le mitage de l’espace. Ces évolutions et dysfonctionnements renvoient à la question de la durabilité du développement des régions, et particulièrement des Alpes, espace contraint géographiquement et objet de nombreuses pressions anthropiques et riche en biotopes remarquables. Cet article est basé sur deux ans de travaux menés par des socio-économistes et des écologues sur les effets sur le paysage et l’environnement de la périurbanisation d’un massif alpin. Nous avons pris en compte l’espace dans les processus environnementaux, économiques ou sociaux. Intrinsèque dans les analyses écologiques, elle a longtemps posé problème à l’économie pour intégrer l’espace comme dimension à part entière des processus économiques. Trois thèmes sont ici développés : l’approche du point de vue du paysage, les problèmes d’échelles spatiales et temporelles, le choix d’indicateurs. Ils demandent de hiérarchiser les questions et de pratiquer le travail en commun. Aller au-delà nécessite de développer une interrogation plus écologique ou plus économique et/ou sociale en quittant de ce fait l’interface pour favoriser des interrogations disciplinaires particulières.Changes in regional landscapes due to urban pressures raise questions regarding land use. They also give rise to economic, social and environmental issues related to urban sprawl, increases in daily commuting, and land consumption. These changes and dysfunctions are ultimately underpinned by the question of sustainable regional development. Mountain regions such as the Alps, with their various outstanding biotopes in a restricted space, are particularly vulnerable.

    Les evaporateurs de refrigeration sont surtout du type tube a ailettes, appeles serpentins, et fonctionnent dans l'une des conditions suivantes: seche, humide ou avec formation de givre. Il a ete demontre que la formation du givre sur la paroi exterieure de l'echangeur engendre une surconsommation energetique a cause des operations de degivrage puisque 15 a 20% seulement de la chaleur produite sert au degivrage tandis que le reste est dissipee dans l'environnement [1]. Avec l'avenement des nouveaux refrigerants, moins nocifs envers l'environnement, l'industrie du froid se trouve penalisee du fait que peu ou pas de composantes mecaniques (compresseur, pompe, echangeur...etc.) adaptees sont disponibles [3]. Il s'agit pour la communaute des frigoristes de combler ce retard technologique en redeveloppant ces composantes mecaniques afin qu'elles soient adaptees aux nouveaux refrigerants. Dans cette optique, et afin de mieux comprendre le comportement thermique des evaporateurs au CO2 fonctionnant dans des conditions seches, qu'un groupe de chercheurs du CanmetENERGIE avaient lance, en 2000, un programme de R & D. Dans le cadre de programme un outil de simulation des evaporateurs au CO2 a ete developpe et un banc d'essai contenant une boucle secondaire de refrigeration utilisant le CO2 comme refrigerant a ete construit.

  2. Effets des electrons secondaires sur l'ADN

    Boudaiffa, Badia

    Les interactions des electrons de basse energie (EBE) representent un element important en sciences des radiations, particulierement, les sequences se produisant immediatement apres l'interaction de la radiation ionisante avec le milieu biologique. Il est bien connu que lorsque ces radiations deposent leur energie dans la cellule, elles produisent un grand nombre d'electrons secondaires (4 x 104/MeV), qui sont crees le long de la trace avec des energies cinetiques initiales bien inferieures a 20 eV. Cependant, il n'y a jamais eu de mesures directes demontrant l'interaction de ces electrons de tres basse energie avec l'ADN, du principalement aux difficultes experimentales imposees par la complexite du milieu biologique. Dans notre laboratoire, les dernieres annees ont ete consacrees a l'etude des phenomenes fondamentaux induits par impact des EBE sur differentes molecules simples (e.g., N2, CO, O2, H2O, NO, C2H 4, C6H6, C2H12) et quelques molecules complexes dans leur phase solide. D'autres travaux effectues recemment sur des bases de l'ADN et des oligonucleotides ont montre que les EBE produisent des bris moleculaires sur les biomolecules. Ces travaux nous ont permis d'elaborer des techniques pour mettre en evidence et comprendre les interactions fondamentales des EBE avec des molecules d'interet biologique, afin d'atteindre notre objectif majeur d'etudier l'effet direct de ces particules sur la molecule d'ADN. Les techniques de sciences des surfaces developpees et utilisees dans les etudes precitees peuvent etre etendues et combinees avec des methodes classiques de biologie pour etudier les dommages de l'ADN induits par l'impact des EBE. Nos experiences ont montre l'efficacite des electrons de 3--20 eV a induire des coupures simple et double brins dans l'ADN. Pour des energies inferieures a 15 eV, ces coupures sont induites par la localisation temporaire d'un electron sur une unite moleculaire de l'ADN, ce qui engendre la formation d'un ion negatif transitoire

  3. Perception as a closed-loop convergence process.

    2016-05-09

    Perception of external objects involves sensory acquisition via the relevant sensory organs. A widely-accepted assumption is that the sensory organ is the first station in a serial chain of processing circuits leading to an internal circuit in which a percept emerges. This open-loop scheme, in which the interaction between the sensory organ and the environment is not affected by its concurrent downstream neuronal processing, is strongly challenged by behavioral and anatomical data. We present here a hypothesis in which the perception of external objects is a closed-loop dynamical process encompassing loops that integrate the organism and its environment and converging towards organism-environment steady-states. We discuss the consistency of closed-loop perception (CLP) with empirical data and show that it can be synthesized in a robotic setup. Testable predictions are proposed for empirical distinction between open and closed loop schemes of perception.

    2001-01-01

    Cet ouvrage illustre en quoi les TIC jouent un rôle si important en pédagogie universitaire et pourquoi ce virage technologique est devenu incontournable. Les auteurs font une place tant aux expériences qu'aux théories sur l'intégration des TIC. Il est question de la diversité des formes de recours aux TIC, des enjeux de leur intégration en milieu universitaire, des défis sociaux sous-jacents à cette incursion technologique, des cours sur le Web, de l'apprentissage collaboratif, de la supervision des stagiaires et de la réforme scolaire.

Nous nous proposons de montrer, dans cet article, dans quelle mesure les deux traditions en sciences du langage ont trouvé matière à exploiter ces corpus en ligne en empiétant, parfois, l’une comme l’autre, sur leurs « territoires » respectifs. Dans cette perspective, nous commençons par mettre au jour l’apport des chercheurs revendiquant leur appartenance à l’analyse du discours, puis celui des chercheurs relevant de l’analyse des interactions et nous montrons les zones de tuilage entre les deux courants. Dans une dernière partie, nous nous intéressons aux défis juridiques, techniques et épistémologiques que doit relever le linguiste qui cherche à étudier des corpus multimodaux en ligne qui prennent des formes de plus en plus sophistiquées et complexes.

    Since most of the empirical work on risk perception has been conducted in the 1970s and few studies are available that claim to span the full range of psychological, sociological and cultural variables, the Center of Technology Assessment in Stuttgart (Germany) has conducted a representative survey in the German State of Baden-Wuerttemberg on risk perception in the general population. In addition, a qualitative investigation based on a sample of 62 respondents was launched in 2001. The objective of the study was to determine the relative importance of psychometric, stigma-related, social value-related, trust-related and cultural variables in explaining risk perception and acceptance. The following report summarizes the results of these investigations. (orig.) [German] Da ein Grossteil der empirischen Forschung in der Risikowahrnehmung in den siebziger Jahren stattgefunden hat und wenige Studien vorliegen, die den Anspruch erheben, den vollen Umfang psychologischer, soziologischer und kultureller Variablen zu erfassen, hat die Akademie fuer Technikfolgenabschaetzung in Baden-Wuerttemberg im Jahr 2001 eine repraesentative Umfrage zum Thema Risikowahrnehmung in der Bevoelkerung Baden-Wuerttembergs durchgefuehrt. Daran wurde eine qualitative Untersuchung auf der Basis eines Samples mit 62 Befragten angeschlossen. Das Ziel der Studie war die Bestimmung der relativen Wichtigkeit psychometrischer, stigma-bezogener, gesellschaftlich wertbezogener, vertrauensbezogener und kultureller Variablen bei der Erklaerung von Risikowahrnehmung und -akzeptanz.

    Research purpose: The aim of this study was to test the technology acceptance model within a South African SAP® Enterprise Resource Planning user environment. Motivation for the study: No study could be traced in which the technology acceptance model has been evaluated in the South African context. Research approach, design and method: A cross-sectional survey design was used. The 23-item Technology Acceptance Model Questionnaire was deployed amongst SAP® Enterprise Resource Planning users (N = 241. Main findings: The results confirmed significant paths from perceived usefulness of the information system to attitudes towards and behavioural intentions to use it. Furthermore, behavioural intention to use the system predicted actual use thereof. Perceived ease of use indirectly affected attitudes towards and behavioural intentions to use via perceived usefulness of the information system. Practical/managerial implications: Practitioners should build user confidence by ensuring the ease of use of a new system, providing relevant education, training and guidance and reiterating its usefulness and future added value to the user’s job and career. Contribution/value-add: This study contributes to scientific knowledge regarding the influence of individuals’ perceptions of information system usage on their attitudes, behavioural intentions and actual use of such a system.

    Electronic health records (EHRs) are increasingly being implemented in healthcare organizations but little attention has been paid to the degree to which nurses as end-users will accept these systems and subsequently use them. To explore nurses' perceptions of usefulness and ease-of-use of EHRs. The relationship between these constructs was examined, and its predictors were studied. A national exploratory study was conducted with 1539 nurses from 15 randomly selected hospitals, representative of different regions and healthcare sectors in Jordan. Data were collected using a self-administered questionnaire, which was based on the Technology Acceptance Model. Correlations and linear multiple regression were utilized to analyze the data. Jordanian nurses demonstrated a positive perception of the usefulness and ease-of-use of EHRs, and subsequently accepted the technology. Significant positive correlations were found between these two constructs. The variables that predict usefulness were the gender, professional rank, EHR experience, and computer skills of the nurses. The perceived ease-of-use was affected by nursing and EHR experience, and computers skills. This study adds to the growing body of knowledge on issues related to the acceptance of technology in the health informatics field, focusing on nurses' acceptance of EHRs.

    2013-12-03

    We assessed the influence of the Fukushima nuclear accident (FNA) on the Chinese public's attitude and acceptance of nuclear power plants in China. Two surveys (before and after the FNA) were administered to separate subsamples of residents near the Tianwan nuclear power plant in Lianyungang, China. A structural equation model was constructed to describe the public acceptance of nuclear power and four risk perception factors: knowledge, perceived risk, benefit, and trust. Regression analysis was conducted to estimate the relationship between acceptance of nuclear power and the risk perception factors while controlling for demographic variables. Meanwhile, we assessed the median public acceptable frequencies for three levels of nuclear events. The FNA had a significant impact on risk perception of the Chinese public, especially on the factor of perceived risk, which increased from limited risk to great risk. Public acceptance of nuclear power decreased significantly after the FNA. The most sensitive groups include females, those not in public service, those with lower income, and those living close to the Tianwan nuclear power plant. Fifty percent of the survey respondents considered it acceptable to have a nuclear anomaly no more than once in 50 y. For nuclear incidents and serious incidents, the frequencies are once in 100 y and 150 y, respectively. The change in risk perception and acceptance may be attributed to the FNA. Decreased acceptance of nuclear power after the FNA among the Chinese public creates additional obstacles to further development of nuclear power in China and require effective communication strategies.

  1. Fair play in energy policy decisions: Procedural fairness, outcome fairness and acceptance of the decision to rebuild nuclear power plants

    2012-01-01

    To raise public acceptance of new energy policies, promoting the fairness of the outcomes and of the decision-making procedure has been suggested. Very few studies have examined the role of fairness in public acceptance of rebuilding nuclear power plants. Therefore, using a large mail survey, we investigated the public’s acceptance of the decision to rebuild nuclear power plants in Switzerland by 2020. The study examined the influence of procedural fairness and outcome fairness on the acceptance of this decision, as well as other factors such as risk perception and benefit perception. Additionally, we investigated the moderating influence of general attitudes towards nuclear power on the relation between fairness and decision acceptance. Results indicated that outcome fairness strongly increased decision acceptance, along with general attitudes towards nuclear power and perceived economic benefits. Procedural fairness had only a small impact on decision acceptance. The influence of fairness on decision acceptance did not seem to depend on general nuclear attitudes. Our findings imply that, in the case of rebuilding nuclear power plants, perceived benefits and outcome fairness are important determinants of acceptance of the decision, while procedural fairness only has a limited impact. - Highlights: ► We investigated the role of fairness in the acceptance of a nuclear policy decision. ► Outcome fairness strongly influenced decision acceptance regarding nuclear power plants. ► The role of procedural fairness was relatively small in this respect. ► Also, nuclear attitudes and perceived economic benefits affected decision acceptance. ► Outcome fairness seems more relevant for decision acceptance than procedural fairness.

    2004-01-01

    The aim of this work is to describe the relationship between self-esteem and characteristics of self image and acceptance of parents and the characteristics of their images in the perception of patients with anorexia nervosa. The test group consisted of 30 patients diagnosed with anorexia nervosa undergoing a treatment in the Department of Psychiatry of the Medical Academy in Lublin. The average age of the examined patients was 20 years. All patients had secondary education. In my work the ACL Gough and Heilbrun Adjectival Test was used which was completed by the examined women three times following the instruction: "I am", "my mother is", "my father is". As a result the actual images of the patients as well as of their mothers and fathers were obtained. The esteem rates were calculated by comparing the number of positive adjectives to the number of negative adjectives used by the patients to evaluate individual persons. The interdependencies between esteem rates and the characteristics of the actual images of these persons were determined based on the r-Pearson correlation. The results obtained indicated the existence of crucial statistic dependencies between the variables analysed and constituted the basis for the formulation of the following conclusions: 1. Patients are characterised by a low self-esteem and a low acceptance level of their parents. They accept their fathers in the smallest degree, compared to that their self-esteem is higher and the acceptance of their mothers is the highest. 2. Self-esteem is related in a significant way to the characteristics of self image such as: sense of responsibility, autonomy, ability to accomplish life objectives and establishing close relationships with other people. 3. The acceptance of their mothers is related to the characteristics typical of them such as: protectiveness, ability to establish and maintain positive interpersonal relationships, empathy and understanding the motives of their own behaviour and those of

    Savard, Stephane

    Les premieres etudes d'antennes a base de supraconducteurs a haute temperature critique emettant une impulsion electromagnetique dont le contenu en frequence se situe dans le domaine terahertz remontent a 1996. Une antenne supraconductrice est formee d'un micro-pont d'une couche mince supraconductrice sur lequel un courant continu est applique. Un faisceau laser dans le visible est focalise sur le micro-pont et place le supraconducteur dans un etat hors-equilibre ou des paires sont brisees. Grace a la relaxation des quasiparticules en surplus et eventuellement de la reformation des paires supraconductrices, nous pouvons etudier la nature de la supraconductivite. L'analyse de la cinetique temporelle du champ electromagnetique emis par une telle antenne terahertz supraconductrice s'est averee utile pour decrire qualitativement les caracteristiques de celle-ci en fonction des parametres d'operation tels que le courant applique, la temperature et la puissance d'excitation. La comprehension de l'etat hors-equilibre est la cle pour comprendre le fonctionnement des antennes terahertz supraconductrices a haute temperature critique. Dans le but de comprendre ultimement cet etat hors-equilibre, nous avions besoin d'une methode et d'un modele pour extraire de facon plus systematique les proprietes intrinseques du materiau qui compose l'antenne terahertz a partir des caracteristiques d'emission de celle-ci. Nous avons developpe une procedure pour calibrer le spectrometre dans le domaine temporel en utilisant des antennes terahertz de GaAs bombarde aux protons H+ comme emetteur et detecteur. Une fois le montage calibre, nous y avons insere une antenne emettrice dipolaire de YBa 2Cu3O7-delta . Un modele avec des fonctions exponentielles de montee et de descente du signal est utilise pour lisser le spectre du champ electromagnetique de l'antenne de YBa 2Cu3O7-delta, ce qui nous permet d'extraire les proprietes intrinseques de ce dernier.

  17. Perception and acceptance of risk from radiation exposure in space flight

    International Nuclear Information System (INIS)

    Slovic, P.

    1997-01-01

    There are a number of factors that influence how a person views a particular risk. These include whether the risk is judged to be voluntary and/or controllable, whether the effects are immediate or delayed, and the magnitude of the benefits that are to be gained as a result of being exposed to the risk. An important aspect of the last factor is whether those who suffer the risks are also those who stand to reap the benefits. The manner in which risk is viewed is also significantly influenced by the manner in which it is framed and presented. In short, risk does not exist in the world independent of our minds and cultures, waiting to be measured. Assessments of risk are based on models whose structure is subjective and associated evaluations are laden with assumptions whose inputs are dependent on judgments. In fact, subjectivity permeates every aspect of risk assessment. The assessment of radiation risks in space is no exception. The structuring of the problem includes judgments related to the probability, magnitude, and effects of the various types of radiation likely to be encountered and assumptions related to the quantitative relationship between dose and a range of specific effects, all of which have associated uncertainties. For these reasons, there is no magic formula that will lead us to a precise level of acceptable risk from exposure to radiation in space. Acceptable risk levels must evolve through a process of negotiation that integrates a large number of social, technical, and economic factors. In the end, a risk that is deemed to be acceptable will be the outgrowth of the weighing of risks and benefits and the selection of the option that appears to be best

    Le travail de recherche effectue dans le cadre de ce projet de doctorat a permis la mise au point d'une methode de mesure des pertes ac destinee a l'etude des supraconducteurs a haute temperature critique. Pour le choix des principes de cette methode, nous nous sommes inspires de travaux anterieurs realises sur les supraconducteurs conventionnels, afin de proposer une alternative a la technique electrique, presentant lors du debut de cette these des problemes lies a la variation du resultat des mesures selon la position des contacts de tension sur la surface de l'echantillon, et de pouvoir mesurer les pertes ac dans des conditions simulant la realite des futures applications industrielles des rubans supraconducteurs: en particulier, cette methode utilise la technique calorimetrique, associee a une calibration simultanee et in situ. La validite de la methode a ete verifiee de maniere theorique et experimentale: d'une part, des mesures ont ete realisees sur des echantillons de Bi-2223 recouverts d'argent ou d'alliage d'argent-or et comparees avec les predictions theoriques donnees par Norris, nous indiquant la nature majoritairement hysteretique des pertes ac dans nos echantillons; d'autre part, une mesure electrique a ete realisee in situ dont les resultats correspondent parfaitement a ceux donnes par notre methode calorimetrique. Par ailleurs, nous avons compare la dependance en courant et en frequence des pertes ac d'un echantillon avant et apres qu'il ait ete endommage. Ces mesures semblent indiquer une relation entre la valeur du coefficient de la loi de puissance modelisant la dependance des pertes avec le courant, et les inhomogeneites longitudinales du courant critique induites par l'endommagement. De plus, la variation en frequence montre qu'au niveau des grosses fractures transverses creees par l'endommagement dans le coeur supraconducteur, le courant se partage localement de maniere a peu pres equivalente entre les quelques grains de matiere
