With a primary focus on Health Canada (HC) and the Canadian Food Inspection Agency (CFIA), this thesis describes the state of microbial related public involvement and risk communication undertakings. The findings show that HC engages with experts to a far greater extent than with the lay public and that HC has not upheld its stated commitment to transparency. Furthermore, both HC’s and the CFIA´s approach to risk communication is overly general, has failed to provide opportunities for dialogue with vulnerable groups and is not rooted in foodborne surveillance data. Public involvement in food safety governance would be improved if HC provided the lay public with a seat on advisory committees and improved its reporting methods. HC and the CFIA could also make improvements by creating opportunities for dialogue between officials and the general public, and by exploring the potential use of alternative risk communication vehicles, such as food labels.

This thesis contributes to developing an evidence-based toolkit for designers when designing products based on theoretical inputs from human-factors study. Theoretical and developmental knowledge, relevant to the design of warning and risk communications and the area of design for child safety, is translated into support for reflections to practitioners. The risk management framework derived from this study aims to increase awareness of the implications of the aspects involved and as a reference point for groups involved in design for child safety. The thesis covers a shift from risk communications with children to information about children (including physical dimensions etc.) for designers. The final output is a collation of this knowledge base and some conceptual tools that can be applied to a specific design context whether that context be in risk communications or the area of general safety design considerations. Designers with little experience in managing design for children can benefit from this study when deciding on their design strategies. This reflective support is the result of a study of risk communication as a complex and unique activity in which various groups and domains are involved. The process of building an understanding started with an analysis of the literature in the field and with the direct experience of the researcher, who worked directly within ergonomics as part of a design-innovation team. The framework presented in this thesis follows a more structured approach to risk communications. It is conceived as an aid to help practitioners reflect on the implications each stage of the development process has on the experience of developing appropriate risk communications and appropriate products. In this way, it is thought of as a dynamic and flexible reference that can be adapted by design researchers when planning and coordinating design to suit different design situations. The use of this tool in the childsafety, design, and study communities would provide validation of the effectiveness of the framework and its continuous improvement. The purpose of this study is twofold: to contribute to study and practice with the aim of providing fundamental guidance to designers. The research detailed in this thesis brings readers up-to-date with the current literature on theories of risk communications. It then highlights methodologies, tools, guidelines and requirements for risk communication advances in study and practice. A framework for risk communication for young children has been developed out of a resource review based on previous work in the area by McLaughlin and Mayhorn, (2014). The information accumulated in this study has been used to develop initial prototype tools for designers who are considering young children. The developed platform supports practitioners from two different angles: theoretical and practical. Designers engaged in the core activity of design for child safety need methods that support the consideration of ergonomics and other product requirements, such as risk communications. This study contributes to developing methods and tools that can be used by designers and other relevant groups when designing risk communications for young children. Available knowledge is collated and integrated into the framework with the intention that it will be developed further throughout the thesis to consider effective use within the design cycle. This study aims to contribute to child safety by providing the first development of tools/decision supports aimed at designers who are designing for young children and are accordingly evaluating human-factors methods in design for child safety. The aim of this study is to gather the requirements of a collaborative design tool for use by industrial designers, engineers and other groups involved in design for child safety. This thesis aims to address these needs. When considering the needs, limitations and capabilities, ( mental model ) of the intended users (i.e., children), important aspects such as safety have been considered. The general need for support methods are addressed through a review of the safety, design and ergonomics literature. After this, empirical study through interviews and observations is used to outline some problem areas: the development and implementation of human-factors methods in design, lack of available resources and inaccessibility of data. Three empirical studies were conducted to meet the requirements of this study: Study 1 in Chapter 4 involves documentary analysis of existing models and methods, Study 2 in Chapter 5 involves formal interviews with designers (N = 30), and Study 3 in Chapter 7 involves an online survey for initial feedback about the prototype-persona (N = 50) respondents. The first section outlines the study questions. It discusses the outputs of the three main studies contained within this thesis.

The use of social media and other communication technologies have created a new ecology of public messaging. As it is a core task of government to inform its residents about risks, public managers and emergency managers, specifically, must understand this new ecology if they are to effectively communicate with the public. A challenge of this new media environment is the differential access of members of the community to various technologies. Partial proportional odds regression (PPO) provides a strategy that is useful to separate effects of access from effects of use. This article illustrates the use of PPO regression to separate access and use effects based on a survey which followed a series of severe weather events in the spring of 2016. The survey includes an address-based sample of residents in the state of Oklahoma to ask about the use of various communication technologies to share information about the weather system (among other subjects). We find that age and work status are related to access while income, gender, race and exposure to extreme weather are related to use of various communication media. This information provides emergency managers with a stronger foundation for developing a portfolio of information options for their communities.

Cancer clusters constitute geographical areas where the frequency of cancer diagnoses during a given period of time occur more frequently than expected by chance. Cancer clusters can impact perceptions of risk and generate significant anxiety in communities. Unfortunately, cluster investigations rarely yield the answers citizens seek around a definitive cause of cancer due to the long latency of cancer and other factors. As a result, health officials may appear to be withholding information and not doing enough to address public concerns. Effective cancer risk communication may also be hindered by other stakeholders such as the media, who sometimes sensationalize risks from environmental hazards, which can distort the public’s perceptions of risks. The result may be a community dissatisfied with a cluster investigation’s results, or worse, a community that distrusts local leaders and doesn’t understand the information reported by expert officials. The four studies comprising this dissertation aimed to summarize key issues with the communication of and investigation of cancer clusters in Canada; test the impact of different types of cancer information on risk perceptions; and explore whether individual characteristics and skills were linked to positive attitudes about coping with cancer risks. An analysis of cancer news coverage and interviews with Canadian public health officials revealed that communities may be receiving inadequate and inconsistent information about cancer risks during cluster investigations. In addition, an experiment and survey revealed information trustworthiness and individuals’ numeracy and health literacy to be important factors shaping cancer risk perceptions and attitudes. This work has significant implications for risk communicators and educators seeking improved methodologies of cancer risk communication and risk education to (1) manage differences in cancer risk perceptions between experts and non-experts (2) enhance public trust in institutions and perceptions of expert competence and (3) inform future educational interventions that promote cancer coping beliefs. / Dissertation / Doctor of Science (PhD) / Cancer clusters constitute geographical areas where the frequency of cancer diagnoses during a given period of time occur more frequently than expected by chance. Cancer clusters can generate significant anxiety in communities and influence perceptions of personal safety and health. As cluster investigations rarely yield the answers citizens seek around a definitive cause of cancer, health officials may appear to be withholding information and not doing enough to address public concerns. The objectives of this dissertation were to summarize key issues with the communication of and investigation of cancer clusters in Canada; test the impact of different types of cancer information on risk perceptions; and explore whether individual characteristics, expertise and skills were linked to positive attitudes about coping with cancer risks. This work provides insights into the diverse ways that people interpret cancer information and perceive risk and identifies improved methods of conducting cancer risk communication and risk education.

Yes / Communication is fundamental to the transfer of information between individuals, agencies and organizations, and therefore, it is crucial to planning and decision-making particularly in cases of uncertainty and risk. This paper brings forth some critical aspects of communication that need to be acknowledged and considered while managing risks. Most of the previous studies and theories on natural hazards and disaster management have limited perspective on communication, and hence, its implication is limited to awareness, warnings and emergency response to some selected events. This paper exposes the role of communication as a moderator of not just risk interpretation and action but also various factors responsible for shaping overall response, such as individual decision-making under uncertainty, heuristics, past experiences, learning, trust, complexity, scale and the social context. It suggests that communication is a process that influences decision-making in multiple ways, and therefore, it plays a critical role in shaping local responses to various risks. It opens up the scope for using communication beyond its current use as a tool to manage emergency situations. An in-depth understanding of ongoing communication and its implications can help to plan risk management more effectively over time rather than as a short-term response.

The Crisis and Emergency-Risk Communication (CERC) model is effective in providing communication recommendations for public health agencies and shows potential for use by other agencies with similar crises characterizations. The current study explores the challenges of earthquake scientists in communicating earthquake risk during the pre-crisis stage in order to grasp experts’ experience and gain insight into the complex and multifaceted world of communicating earthquake risk. The researcher integrates the in-depth knowledge with the recommendations of the pre-crisis stage of the CERC model. This study employs qualitative interviewing with earthquake scientists (N = 21) from the Southern California Earthquake Center (SCEC). Categorized under general challenges, communication challenges, and communicating probability challenges, findings from this study indicate that earthquake scientists face eight unique challenges, such as communicating uncertainty, emphasizing their responsibility as solely hazard communicators, and keeping public attention during earthquake quiet periods. Implications for earthquake scientists during the pre-crisis stage of CERC are discussed and recommendations are provided.

CHDS State/Local / Approved for public release; distribution is unlimited / A potentially serious gap exists in the preparedness of the public health system to respond to terrorism: risk communication. Unless this system is better structured to provide American citizens with a clear understanding of the potential risks and hazards associated with a terrorist event -- particularly a bio-terrorism event -- citizens not only run the risk of taking inappropriate protective actions, but also of experiencing increased (and potentially debilitating) levels of fear. In a survey I conducted of public health officials in an eleven state region (which includes my own state, Colorado) I found that significant opportunities for improvement exist in their emergency preparedness planning. Of particular concern, there was limited risk communication planning. Nonetheless, there was a high level of confidence in the states' perceived level of preparedness to respond and communicate risks during a potential bio-terrorism event. / Civilian, Manager - Emergency Management Program, Colorado Department of Public Health and Environment

The goal of risk communication is to inform people about the risks they face and to encourage them to take appropriate action in response to that threat. To achieve this goal, risk communication scholars continuously examine the messages surrounding crises and disasters, and engage in message-testing to evaluate theory-driven message designs. Recent communication scholarship recommends that messages should including instructing information (Coombs, 2012), and should take into consideration established pedagogy based on instructional communication research (Sellnow & Sellnow, 2010). This dissertation continues to build on research which applies instructional communication scholarship to risk communication messaging. Using message-testing, this dissertation examined the utility of the IDEA model a message design for earthquake early warnings.
