Public Image Of Chemistry

The public image of chemistry is a relevant issue for chemical stakeholders. It has been studied throughout history by means of document analysis and more recently through surveys. Twitter, a worldwide online social network, is based on spontaneous opinions. We tried to identify the public perception of chemistry on Twitter, what it explains, and which sentiments are perceived. We gathered 256 833 tweets between 1st January 2015 and 30th June 2015 containing the words “chemistry”, “chemical” or “chem”. We cleaned and filtered them down to 50 725 tweets with textual information in English and clustered them using spherical k-means. The resulting clusters were categorised according to six topics by 18 chemistry experts. The prevailing topics were the learning environment topic, related to activities and tasks in chemistry courses, and the human activity topic, referring to facts and news about the chemical industry. The scientific knowledge topic, concerning communication of chemistry knowledge, only accounted for a small percentage of the tweets. We classified the tweets of most relevant topics based on their sentiment values and obtained more positive than negative perceptions. Nevertheless, the analysis of the unigrams and bigrams word clouds revealed a significant presence of chemophobia-related terms in the human activity topic, both in positive and negative classified tweets. It also revealed specific elements of chemistry courses negatively perceived in the learning environment topic.

Background: There has been a decrease in the number of IUD family planning acceptors in the last three years, from 3.69% in 2016 to 3% in 2017 and 2018. One factor in the low use of IUD contraceptives is public perception. The way to change people's negative perceptions about the IUD is to provide health education.Objectives: To review several journals about effect of health education about iud (intrauterine) device uses group discussion and brainstorming on the level of knowledge and attitudes fertile age couples.Methods: The study is a literature review method based on the articles searched on Google Scholar and PubMed. The keywords used to find articles were using the keywords "Health Education, IUD, Group Discussion, Brainstorming, Knowledge, and Attitudes". The data obtained were compiled, analyzed and concluded by looking for similarities, inequalities providing views, comparing and summarizing.Results: Literature review shows that there is an effect of health education with the method of group discussion and brainstorming on a person's knowledge and attitudes.Conclusion: Health education using the group discussion method has more influence on increasing knowledge and attitudes. It is hoped of the health institutions can improve health services by providing information through health education to the public about the benefits of intrauterine contraceptives (IUDs).

Using the Activity Vector Analysis (AVA), an adjective check list for measuring self-concept, cross-cultural perceptions were obtained of President Johnson and Premier Kosygin. The three cultures involved in the study were American, Indian, and German. Ss were graduate students at the Universities of Rhode Island (U.S.A.), Panjab (India), and Hamburg (Germany). For the German Ss a German form of the AVA was used. Data were analyzed on the basis of compatibility with three stereotyped personality profiles obtained in earlier studies. These were (1) public perception of Nikita Khrushchev, (2) ideal U.S. President's image, and (3) personality profiles of self-made company presidents in the U.S. There was consensual agreement among Ss of different nationalities, except for the Indian students' perceptions of Kosygin. The Indian Ss as a group perceived Kosygin as possessing a personality structure consistent with the American perception of the ideal U.S. President, and personality traits which are relatively unrelated to both the public image of Khrushchev and the personalities of company presidents. All Ss agreed in that their perception of Johnson was highly related both to the public image of Khrushchev and the personalities of the company presidents and rather unrelated to the ideal U.S. President stereotype.

Linguistic Material

The online social network Twitter, apart from being one of the main vehicles of communication in the cyberspace, has become an effective diffusor of fear of crime. The latter phenomenon has caught the attention of researchers since the 1960’s, amongst other reasons due to the impact on the citizens’ quality of life and consequently the call for its public management. Yet, the evaluation of fear of crime in the cyberspace, and more precisely on Twitter, is practically inexistent to the date.Based on a sample of tweets pertaining to three different hashtags (#prayforbarcelona, #stopislam, and #barcelona), which were gathered during the attacks on Barcelona in August 2017, our study pretends to investigate how users (n = 450) of Twitter perceive tweets to affect the public appraisal of security. These data were contrasted with a database of affective norms for more than 10,000 words in the Spanish language (Stadthagen-González, Ferré, Pérez-Sánchez, Imbault, & Hinojosa, 2017). We correlated the emotive values of tweets (based on their lexicon) with the estimations of our research participants. The results show significant correlations between various discrete basic emotions (fear, happiness, sadness) ) and our participants’ judgements. We achieved the same for one continuous emotional dimension (valence). This study shows, even though not conclusively, that the emotion transported via the linguistic material has an impact on the estimated likelihood of affecting the public perception of security when elicited in a space of potential crime, specifically in the cyberspace. Our results allow us to (1) continue along this kind of method, contrasting traditional methodology by approaching fear of crime through a combination of Big Data Analysis and linguistic emotion detection in written text. They furthermore allow us to (2) establish the methodological bases to design an automatized detector of fear of crime for Twitter, which we will attempt in a series of follow up studies. Our long-term goal is to program classifying algorithms to identify linguistic material with a high likelihood of affecting the public feeling of security.

This study looked at the effects of framing on the public perception of corporate environmental compliance and government policy, closely mirroring the policy design of the Federal backstop of the Pan-Canadian Framework on Climate Change. There were three key findings. First, companies that simply pay their taxes as a penalty for emissions (“merely complying” with the policy) are considered to be less moral, to have less-acceptable practices and to be harming the environment. Alternatively, companies that invest to decrease their carbon footprint (“proactively engaging” with the policy) are more likely to be perceived as acting morally, having acceptable practices and helping the environment. Secondly, consumers were more willing to bring their business to proactive companies rather than the ones that were strictly complying. Finally, the response of companies also had an effect on citizens’ perception of the policy itself. If companies were engaging proactively rather than merely complying, consumers were more likely to view the carbon pricing policy as fair, to support the political party that implemented it, to ratethe policy as helping the environment, to rate it as helping Canada’s image and reflecting Canadian values, and to rate the policy as helping the economy. There are key implications for both industry and government stakeholders to draw from these findings. For industry, communicating proactive policy engagement improves public image and increases consumer support. For the government, communicating to industry the positive benefits—environmental, economic and social—of proactive engagement could increase overall private-sector engagement and thereby improve the public’s perception of the policy itself. Overall, this suggests that adherencewith and support for carbon pricing policies is a promising opportunity for the private sector to signal their environmental and social commitments.

Abstract. Communicating information about geological and hydrological hazards relies on appropriately worded communications targeted at the needs of the audience. But what are these needs, and how does the geoscientist discern them? This paper adopts a psychological "mental models" approach to assess the public perception of the geological subsurface, presenting the results of attitudinal studies and surveys in three communities in the south-west of England. The findings reveal important preconceptions and misconceptions regarding the impact of hydrological systems and hazards on the geological subsurface, notably in terms of the persistent conceptualisation of underground rivers and the inferred relations between flooding and human activity. The study demonstrates how such mental models can provide geoscientists with empirical, detailed and generalised data of perceptions surrounding an issue, as well reveal unexpected outliers in perception that they may not have considered relevant, but which nevertheless may locally influence communication. Using this approach, geoscientists can develop information messages that more directly engage local concerns and create open engagement pathways based on dialogue, which in turn allow both geoscience "experts" and local "non-experts" to come together and understand each other more effectively.

Abstract. Communicating information about geological and hydrological hazards relies on appropriately worded communications targeted at the needs of the audience. But what are these needs and how does the geoscientist discern them? This paper adopts a psychological "mental models" approach to assess the public perception of the geological subsurface and surveys three communities in the south-west of England about their attitudes and representations of the geological subsurface. The findings reveal important preconceptions and misconceptions regarding the impact of hydrological systems and hazards on the geological subsurface, notably in terms of the persistent conceptualisation of underground rivers and the inferred relations between flooding and human activity. The study demonstrates how such mental models can provide geoscientists with empirical, detailed and generalised data of perceptions surrounding an issue, as well reveal unexpected outliers in perception that they may not have considered relevant, but which nevertheless may locally influence communication. Using this approach, researchers and communicators can develop information messages that more directly engage local concerns and create open engagement pathways based on dialogue, which in turn allow both groups to come together and understand each other more effectively.

"Feminist Interpretations of Action and the Public in Hannah Arendt’s Theory. Arendt’s typology of human activity and her arguments on the precondition of politics allow for a variety in interpretations for contemporary political thought. The feminist reception of Arendt’s work ranges from critical to conciliatory readings that attempt to find the points in which Arendt’s theory might inspire a feminist political project. In this paper I explore the ways in which feminist thought has responded to Arendt’s definition of action, freedom and politics, and whether her theoretical framework can be useful in a feminist rethinking of politics, power and the public realm. Keywords: Hannah Arendt, political action, the Public, the Social, feminism "
