This DPhil thesis discusses how two divergent risk conceptions, a 'social view' and an 'economic view' of risk, are constructed through inter-expert risk communication. Different and sometimes contradictory concepts of risk are mobilised in regulatory practice, but the origins of these divergent risk conceptions are not extensively studied. This thesis seeks to unpack this divergence. Empirically, I analyse risk communication among experts in the European Union (EU) during the creation of two risk regulation standards. The two case studies, one related to the development of the two-degree target of EU climate policies (the climate case) and the other about the negotiation of the excessive deficit criteria of the Maastricht Treaty (the euro case), can shed light on the relations between risk conceptions and inter-expert risk communication. I argue that through risk communication, an initial 'view' of risk can be entrenched and developed into a paradigmatic 'risk conception'. My analysis uses historical and sociological institutionalism, by focusing on path dependence of risk communication and social construction risk conceptions among EU experts. Through the two case studies, I identify four analytical dimensions of inter-expert risk communication: networks (the institutional setting and relationships between different experts), cultures (the mentalities of experts in relation to discussing risks), dynamics (the actual processes of transmitting and receiving risk messages) and strategies (the rationales supporting the decisions of risk regulation standards). My thematic analysis reveals four key distinct 'features' of social/economic views of risk: expertise (the types of knowledge mobilised), normality (characterising risk as either 'special' or 'routine'), probability (considering risk as either uncertain or calculable) and impact (seeing risk as either negative or positive). I argue that these four features can help explain the construction of risk conceptions, and more broadly, provide an analytical framework for studying how views of risk evolve and interact over time.

This study investigates how heterosexual young people understand and manage risks related to meeting sexual partners online in the United States. The purpose of this study is to help inform the development of culturally-appropriate sexual risk communication and health promotion messages for young people by linking public health knowledge of adolescent sexual health and eHealth with anthropological theories of risk. With qualitative data from two rounds of semi-structured interviews and two group interviews with university students in central Florida, this study shows how young people experience and prioritize more social-emotional risks in meeting online-to-offline sexual partners compared to physical risks. The prominence of these social-emotional risks implies the need for more health promotion messages that incorporate both physical and social-emotional health risk communication.

Rhetorical choices and strategies are central to democratic decision-making, especially regarding decisions on matters that are open for argumentation depending on perspective. The thesis considers public meetings on Swedish nuclear waste management as an example of rhetorical argumentation, specifically in relation to the project of finding a place for final deposition of the high-level spent nuclear fuel – with local geological investigation as a critical part of that project. Project managers have met with other organizations such as protest groups, associations of experts and authorities on several occasions, mainly through local and national hearings. The thesis is guided by a research question regarding the most salient challenges to a resilient rhetorical dialogue for nuclear waste management. The concept of rhetorical dialogue is applied in two ways. Firstly to explain the lack of dialogue that is experienced by participants despite arrangements to reach consensus-oriented dialogue in the Habermasian sense. Secondly in a discussion of rhetorical relations that might explain ambiguity in participants’ interpretations of each other. Three meetings are compared: two local meetings at sites of geological investigation (Kynnefjäll 1979 and Kolsjön 1985) and one national meeting held in Stockholm in 2008. Research materials have been collected from the archives of participating organizations and from interviews with participants. Analyses of these materials are combined with a rhetorical analysis of meeting recordings, with a specific focus on question-reply argumentation. One main conclusion is that the principal rhetorical challenges concern the roles of participants in relation to the rhetorical situation, the establishment of rhetorical genre in the format of hearings, and inclusion of relevant perspectives in the early project phase.

Hypotheses on the efficiency of evidence-based printed materials can be directed by health communication concepts. These concepts can provide a general framework that goes beyond the traditional vulgarization point of view: instead, it points towards a strategy to obtain health outcomes and provoke behavior change, from a disease prevention, management and health promotion perspective. The present study proposes a comprehensive framework based on concepts from health risk communication, Tarde's theory of social values, usability, readability and plain language. Using the mapping approach, an evaluation grid was applied to printed evidence-based materials with proven effectiveness, in order to reveal the underlying strategy and isolate the characteristics of effective materials. The results allowed us to define two types of printed evidence-based materials, according to the robustness of the evidence they contain and the target audience. It was also possible to identify indicators of notions that are translated into operationalized items, frequent in those materials that might be responsible for their efficiency: clear purpose of the documents, limited scope, learning motivation and correspondence to the logic, experience and language of readers. Effectiveness of printed evidence-based materials could also be correlated to numeracy, objectiveness, standard definitions, constant timeframes and denominators, risks enumerated in order of importance, effective response, and high degree of threat, urgency, novelty and visibility of the disease. It was also possible to identify some missing communication concepts: cultural diversity, narrative, increased easiness of procedures and aesthetic advantage for the patient. In the process of work, the theory of social values emerged as a dynamic component that can bring together and explain many concepts, as well as physician’s acceptance of the guidelines. Value in terms of usefulness and truth plays a major role in cognitive appreciation of the documents. This concept gives a strategic meaning to the whole work and allows us to better understand attitude and behavior change.

Thesis (M.A. (Communication Studies)) -- University of Limpopo, 2020 / Hubbly Bubbly smoking is a visibly growing trend among young people globally. However, health promotion about the risks that result from hubbly bubbly smoking has not been vigilant so far. The study attempts to determine youth’s knowledge and perceptions towards the health risks incurred from smoking the HB. The study triangulates three theories namely: The Extended Parallel Process Model, Peer Cluster Theory and Hofstede’s Cultural Theory using a mixed method approach among University of Limpopo students. A sample of 350 students was used, made up of n=175 HB users and n=175 non-users. In the quantitive part of the study, a 2 x 2 between and within respondents design was followed. Most HB users 74% (129) and non-users 80% (140) identified lung cancer as the health risk of HB smoking. Participants perceived HB smoking health risks as exaggerated, and that HB is less addictive and less harmful. The majority of participants (75%) had not heard or seen any health communication awareness campaigns about HB risks. Focus group interviews revealed that participants perceived HB as less harmful, less expensive with no visible health warning and not addictive to every user. Findings suggest that there is inadequacy in terms of knowledge as well as negative perceptions towards HB and its health risks. There should be more health communication campaigns that will engage the youth and the public, and the media should speak more about HB and its health risks. The study contributes to the body of knowledge about health communication campaigns about existing problems. / National Research Foundation (NRF)

The hepatitis A crisis in Kentucky is unprecedented compared to other states. With thousands of hospitalizations and over 60 deaths in the state of Kentucky alone, there is a need to evaluate the government’s response to the hepatitis A virus (HAV) epidemic. Therefore, the instructional risk communication messages that are being conveyed by the Kentucky Cabinet for Health and Family Services (KCHFS) are instrumental in the education and action plans of Kentuckians who are at risk of contracting HAV. This study utilizes the IDEA Model Thematic Analysis Codebook as a guide to analyze the KCHFS’ risk communication regarding the hepatitis A crisis, identifying the strengths and weaknesses of its campaign. Through this research, I identify the weaknesses in the KCHFS’ risk communication campaign including: the need to focus on a more general audience, the need to foreground all facets of the IDEA model on its website, the need to promote the vaccination of the HAV more strongly, and the need to make the website more user-friendly for all populations.

Reclaimed water has increased in popularity as a means to recycle water and thus decrease the amount of wasteful water use. This process is widely used in Tampa Bay for watering of lawns. This increase in popularity and use has raised questions as to what contaminants are in the reclaimed water. The purpose of this study was to analyze reclaimed water for contaminants believed to be detrimental to health and conduct interviews to ascertain perceptions of risk in the local population. As water reuse grows in popularity further research will need to be conducted to address potential human health concerns. This research shows that there are potential health concerns related to reclaimed water when we use dioxin as a surrogate compound. Additionally, the research shows that local governments aren't doing enough to communicate information to local communities. Any policy that moves forward in regards to supplementing drinking water with reclaimed water must incorporate local communities in the decision making process. Decisions made in the absence of information can be misguiding and the first feedback of these decisions is felt by local communities. With their input in the beginning, throughout the decision making process, and during the evaluation period, new information will be generated. The incorporation of the community in the decision making process will make the reclaimed for drinking water initiative, more successful.

abstract: Environmental hazards and disaster researchers have demonstrated strong associations between sociodemographic indicators, such as age and socio-economic status (SES), and hazard exposures and health outcomes for individuals and in certain communities. At the same time, behavioral health and risk communications research has examined how individual psychology influences adaptive strategies and behaviors in the face of hazards. However, at present, we do not understand the explanatory mechanisms that explain relationships between larger scale social structure, individual psychology, and specific behaviors that may attenuate or amplify risk. Extreme heat presents growing risks in a rapidly warming and urbanizing world. This dissertation examines the social and behavioral mechanisms that may explain inequitable health outcomes from exposure to concurrent extreme heat and electrical power failure in Phoenix, AZ and extreme heat in Detroit, MI. Exploratory analysis of 163 surveys in Phoenix, AZ showed that age, gender, and respondent’s racialized group identity did not relate to thermal discomfort and self-reported heat illness, which were only predicted by SES (StdB = -0.52, p < 0.01). Of the explanatory mechanisms tested in the study, only relative air conditioning intensity and thermal discomfort explained self-reported heat illness. Thermal discomfort was tested as both a mechanism and outcome measure. Content analysis of 40 semi-structured interviews in Phoenix, AZ revealed that social vulnerability was associated with an increase in perceived hazard severity (StdB = 0.44, p < 0.01), a decrease in perceived adaptation efficacy (StdB = -0.38, p = 0.02), and an indirect increase (through adaptive efficacy) in maladaptive intentions (StdB = 0.18, p = 0.01). Structural equation modeling of 244 surveys in Phoenix, AZ and Detroit, MI revealed that relationships between previous heat illness experience, perceived heat risk, and adaptive intentions were significantly moderated by adaptive capacity: high adaptive capacity households were more likely to undertake adaptive behaviors, and those decisions were more heavily influenced by risk perceptions and previous experiences. However, high adaptive capacity households had lower risk perceptions and fewer heat illness experiences than low adaptive capacity households. A better understanding of the mechanisms that produce social vulnerability can facilitate more salient risk messaging and more targeted public health interventions. For example, public health risk messaging that provides information on the efficacy of specific adaptations may be more likely to motivate self-protective action, and ultimately protect populations. / Dissertation/Thesis / Doctoral Dissertation Environmental Social Science 2019

The purpose of this thesis was to examine the reactions to Canadian public health organizations' messaging through a social media analysis by answering the following two research questions: 1) How did different levels of government use social media communication to inform the public of COVID-19 information during the reopening phase? 2) What was the public response to the lifting of COVID-19 measures? COVID-19-related Tweets posted by Ottawa Public Health (OPH), Public Health Ontario (PHO), and Health Canada and the Public Health Agency of Canada (HC & PHAC) and their replies were collected using the Twitter API through Python. Sentiment analysis of the data was conducted using the VADER tool. This was followed by a thematic analysis of Twitter threads to identify patterns in the Tweets posted by each organization and their respective replies. Results of the VADER sentiment analysis indicate OPH Tweets were mostly positive, whereas HC & PHAC Tweets were slightly more positive than neutral. PHO Tweets were mostly neutral. Public social media replies to the selected public health organizations were also measured; replies to both OPH and HC & PHAC were more negative than positive, although replies to OPH were slightly more positive compared to replies to HC & PHAC. Thematic analysis revealed five themes regarding public health organizations' use of social media communications and eight themes relating to the public response to information posted by the selected public health organizations. The results from both sentiment and thematic analysis can help inform recommendations to enhance communication by Canadian governmental organizations, especially in public health systems, and offer recommendations for public health social media communication to inform future disaster response policies.
