The risks for Swedish citizens' health increased when the COVID-19 pandemic came to the country and the risk communication started. Risk communication entails attempts to change perceptions, beliefs, attitudes, feelings or behavior according to Breakwell (2014, p.144). Sweden has adopted a different strategy to deal with the pandemic in relation to other Nordic countries. In this thesis we have chosen to look at a vulnerable group, Swedish young adults in age 20 to 30 year olds because they are the one of the most active citizens during the pandemic. This thesis is conducted using a qualitative method and collects empirical data from semi-structured interviews of Swedish young adults. The theoretical concept is centred on risk communication, risk society and decisions-making. Based on research evidence, It is a mixed outcome how young adults choose to deal with the restrictions, some follow them closely and some of them still live a social life as before the pandemic. The study concluded that young adult’s behavioral changes played an important role in society

Remembering negative experiences with extreme heat may promote future protective actions and provide insight to improve heat risk awareness and communication practices. This two-part thesis found 1) that experiencing heat-related health symptoms predicted what Americans would do to protect themselves and others during subsequent heat waves; and 2) that Utah professionals regard heat-related experience as an important factor in how they responded to extreme heat events. In the first study, a US national survey showed that personal experience with heat-related health symptoms was related to the tendency to say that one engaged in different protective behaviors, while other factors like risk perception and temperature were less related to self-reported behaviors. Sociodemographic factors such as age, race, and gender were related to Americans’ reported efforts to check on other people during a heat wave—with African-Americans, women, and older adults being more likely to do so— but did not have much relationship with how people personally protect themselves. The second study found that heat experience was an important factor in how public officials and media broadcasters manage extreme heat situations. Interviews of professionals in Utah revealed that experience with heat impacts influenced public forecasters, practitioners, and media members alike in their heat risk decisions and messaging practices even though official heat risk communication products in Utah were somewhat unfamiliar. This study also found that public forecasters recently changed how they measure extreme heat to better communicate the dangers of dry heat in the Intermountain West. This change will likely cause more official heat alerts to be issued in this region.

This study aims to create a design concept for a digital twin to understand how it could be used to increase the health adherence of users through risk communication. This was done while also looking at how such a system could counteract potential health anxiety. The massive digitization and available data has enabled better opportunities to accurately represent and affect a person’s health in the form of a digital twin. The primary way of conducting the study was by using the ’Design Thinking’ method which incorporates five steps: Empathizing with the users’ needs, defining the problems, ideating, creating prototypes, and finally testing these. A literature study, four user interviews as well as two interviews with healthcare professionals were conducted to get a better understanding of what problems needed to be solved. The findings from these together with a brainstorming session resulted in low fidelity (LoFi) and high fidelity (HiFi) versions of a mobile prototype. A single overview page of a desktop version for health professionals was also created. The mobile prototypes were user tested, and input was asked from stakeholders and healthcare professionals regarding the risk communication and visualization via walkthroughs of the prototypes. The usability results of the tests were positive with the HiFi version scoring 83.5 / 100 on the System Usability Scale which measures usability, and this score is deemed to be ’good’. The risk communication used received positive feedback, and the findings showed that a digital twin could potentially help with adherence and prevention by the use of summaries, visualization, as well as combining icons with the use of absolute risk and frequencies. To minimize the risk of health anxiety, a digital twin could reduce health information that is not very serious or important through a ”less-is-more” approach. Other effective means could be to show positive visualization and by being mindful of the ordering of risks and benefits, showing the user the positive aspects after the negative ones. Despite this, because of the lower sample size and hypothetical test scenario, further studies need to be conducted to verify the validity in more real-life scenarios. More isolated testing should be done to understand the effects better, both in terms of risk communication and usability. Additional things that could be beneficial to look at could be the implementation of gamification elements in the digital twin, further development of a desktop version for healthcare staff, as well as using more personalization options.

This thesis is a philosophical contribution to the theories on risk communication. The topic of risk communication is approached from several different angles, but with a normative focus on equality and vulnerability. Essay I is a comment on risk perception theory and the psychometric model in particular. In risk perception research individual risk taking is described as either a result of valuing the benefits from risk taking or a failure of comprehending the severity or probability of risks. The essay argues that sometimes individuals take risks simply because they are in a vulnerable position and have no other choice. Four factors are identified as crucial in risks from vulnerability: poor outset conditions, lack of reasonable options, hope and liability to disinformation. Essay II addresses the democratic approach to risk communication and the ideal of risk communication as a dialogue between more or less equal stakeholders. The Essay argues that even the more innovative and dialogue oriented approaches to risk communication are unequal. This is often blurred by the confusion between the described ideal and the description of these newer approaches. This inequality is analysed in a three-fold way: influence over the communication process; influence over and access to information; and influence over risk decisions. The Essay develops a typology of different risk communication practices and influence distributions and concludes that the form of risk communication most commonly referred in the literature is the most imbalanced kind where all three types of influence falls to the same party. Essay III explores the concept of trust, an often-mentioned objective for risk communication. The concept of trust is analyzed from previous philosophical approaches, and the idea of trust as comfortable defocusing is introduced. It is argued that not only the gains for the trustee but also the gains and risks for the truster, generally and in the case from risk communication, can be explained by this notion. It is concluded that public trust for institutions or organizations need not be framed on an individual level. Instead, the vulnerability of trusting can be counter-acted by a delegation of different stances, including both control and trust, among different individuals and institutions in society. / QC 20101116

This paper analyzes the NBA's communications efforts from June 4 to July 30, 2020 as it prepared for an unprecedented season restart in the early days of a global pandemic. While scholars have examined the media's framing of the NBA in this period, there is a gap in the literature when looking at the official NBA communications strategy of the organization itself. As the first study to use risk communication theory in a sports scenario while also employing corporate social advocacy as the second theoretical basis of analysis, this qualitative study is a thematic and textual analysis of 14 NBA press releases and three existing video interviews of NBA Commissioner Adam Silver. Findings show that risk communication theory holds up in a sports context as the NBA employed effective use of widely accepted risk communication criteria. The study also puts forth a basis for CSA in sports communication regarding social justice.

Browser security indicators show warnings when sites load without HTTPS, but more malicious sites are using HTTPS to appear legitimate in browsers and deceive users. We explore a new approach to browser indicators that overcomes several limitations of existing indicators. First, we develop a high-level risk assessment framework to identify risky interactions and evaluate the utility of this approach through a survey. Next, we evaluate potential designs for a new risk indicator to communicate risk rather than security. Finally, we conduct a within-subjects user study to compare the risk indicator to existing security indicators by observing participant behavior and collecting feedback. Our results suggest that risk indicators make users more confident in judging their risk and that participants prefer risk indicators over current security indicators. In addition, users take fewer risks in the presence of risk indicators, making this a promising direction for research and implementation into web browsers.
