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.

Magister Artium (Development Studies) - MA(DVS) / The Human Immunodeficiency Virus (HIV) and Acquired Immunodeficiency Syndrome (AIDS) epidemic continue to endanger the lives of many people in the world, particularly in developing countries like South Africa (UNAIDS, 2010). South Africa has the largest percentage of people living with HIV & AIDS in the world, with AIDS continuing to be the leading cause of death(UNAIDS, 2010). Yet, as Svenson et al., (1997), Cain, (2005), Shisana et al., (2009) and Kalichman et al., (2005) argue, in spite of the HIV epidemic, risky sexual behaviour has increased among young people. Problematically, youth in university environments are reported to be uninterested in hearing about HIV, claiming to be tired and bored with the subject (HEAIDS,2010). They think they have sufficient knowledge on HIV transmission and prevention. Regardless of this claim, a high rate of new infections of HIV among youth continues (The South African Department of Basic Education Report, 2010). The main purpose of this study was to assess UWC students’ knowledge about HIV and their attitudes towards it, while investigating the impact of the MTV-produced Shuga film on the students' self-perception of risk and their attitudes toward HIV.The study assesses the value of a follow-up conversation on the film after it is viewed by students. In order to identify respondents' perceptions, the study used a qualitative approach using in-depth interviews and focus group discussions as main instruments and a quantitative approach using questionnaires as a main instrument. The study used a gender-balanced convenience sample of 40 undergraduate and post-graduate students selected from University of Western Cape campus. These respondents were later divided into four focus group discussions guided by semi-structured interviews. The study findings established that although students' knowledge levels were very high for modes of transmission and prevention of HIV, they still had a poor perception of their own risk – a factor noted as a key need in HIV prevention by Douglas Kirby (2011). This study found that, prior to watching the MTV Shuga film, the level of students' awareness of HIV issues as related to their own risk and health was at best inconsistent. While some held accurate knowledge of HIV and understood their own vulnerability, others saw it as someone else's problem and had yet to personalise the disease in a manner that would increase their own awareness of risk. After viewing the MTV Shuga film, study data indicated a reasonable level of positive change in attitudes and risk perception among the 40 students. However, the data clearly indicated that the follow-up discussion sessions provoked more change in the students' attitudes and perceptions of risk than the film on its own. The study therefore suggests the importance of discussion sessions that follow up on edutainment media pieces attempting to promote positive behavioural change vis-à-vis HIV. While the study did not focus in depth on why the follow-up discussion sessions had a higher impact than film-viewing alone, the discussion sessions allowed students to personalise the content of the Shuga film, sharing with each other how they identified with various characters, situations and behaviours. Shuga became 'real' through the personal discussions between students, and the film's intent to prompt positive change was further supported.

Aquatic pharmaceutical pollution poses ecotoxicological risks to the environment and human health. Consumer attitudes and behavior represent a significant source of pharmaceutical compounds found in water. Thus, understanding public perceptions of aquatic pharmaceutical pollution and developing effective risk communication techniques are critical to engaging society in the type of widespread change necessary for addressing the presence of pharmaceuticals in water. This mixed-methods study applies conceptual metaphor theory in conjunction with construal level theory of psychological distance to assess how metaphoric framing affects perceptions of aquatic pharmaceutical contamination across four principal dimensions of psychological distance (geographic, social and temporal distance and uncertainty). Additionally, this study assesses the direct impact of metaphor use on concern and willingness to act, which are positively associated with perceived psychological distance. Data were collected from a convenience sample (n = 20) of university students in Burlington, Vermont using cognitive interviewing. Results indicate that pharmaceutical pollution was initially perceived as geographically distant, socially distant, temporally both proximate and distant and certain (versus uncertain). Our findings suggest people perceive distances in various ways, suggesting a need for validated questions to consistently measure psychological distance. Participants preferred the metaphorically-framed visual intervention to the non-metaphor visual intervention. Further, participants’ perception of pharmaceutical pollution changed to being more geographically and socially close after viewing the metaphoric visual only. Previous research indicates perceived psychological closeness leads to increased motivation and preparedness to act. Theoretical and practical implications of metaphor use in risk communications are discussed.

The purpose of this study was to investigate how school principals understand HIV/AIDS and how their knowledge, attitude and interpretation filter in the implementation of the HIV policy in schools. The study comprises a literature review and empirical investigation. The results of this study can be used in planning and implementing HIV policy in schools. The data were collected by administering semi-structured interviews. Ten school principals from the Dennilton circuit in Southern Region of the Limpopo Province were interviewed. The results show that the majority of the principals involved in the study confirm that HIV/AIDS is an incurable disease caused by a virus and is mainly sexually transmitted. Some principals regard their school safe from HIV infection. Their assumption is based on the absence of HIV positive learners and educators in their schools. The principals are aware of the rights of HIV positive learners and educators. Significantly, the research findings indicate that the majority of schools lack educators with HIV/AIDS training, rules on safety precautions and first aid kits. It is recommended that ongoing HIV/AIDS training programmes be provided for educators to enable them to educate the youth on HIV/AIDS. Additionally, schools should focus on strategies to implement universal safety precautions against HIV transmission and to obtain first aid kits. Lastly, school principals should involve parents and other stakeholders in creating a positive school environment for HIV positive learners and educators. / Dissertation (MEd (Education Management))--University of Pretoria, 2005. / Education Management and Policy Studies / unrestricted

The thesis focuses on estimation of household total risk exposure and factors affecting this estimation. The risk is represented with a financial loss of 20k CZK in the next month and with a financial loss of 50k CZK in the next 12 months. Nearly a half of participants in the survey (n=55) estimates the likelihood of this financial shock as being low, however the number of participants with high estimate increases for the next 12 months. The estimate of total risk exposure increases with age, for self-employed and single parents, next with income and assets, however overall wealth decreases the estimate. Significant factors are education, financial behaviour and cognitive abilities which all have a decreasing effect on the estimate. Availability is considered as significant having a positive effect while biased evaluation of risks has a negative effect. Time preferences can play an important role in the estimation of a long-term risk.

Traveling around the world is a highly appreciated phenomenon globally. In recent years, backpacking has grown in popularity. Characterised by simplicity and adventurousness, it is especially frequent within a young demographic. However, these types of trips produce certain risks to consider, with women being subject to greater risks in the society in large. This study aims to examine risk perception amongst young female backpackers. It was performed using a qualitative method based on 15 semi-structured interviews. Results showed that risk perception has a large impact on women’s chosen destination, with certain destinations subsequently being deselected. Moreover, variable risk perception can be observed over time, in response to the decision process. At commencement, high perception of risk was exhibited, yet later shown to gradually decrease as the trip progressed. Finally, an increased perception of risk was noted post returning from the journey. / Intresset för resor har ökat i stor omfattning. En växande trend under den senaste tiden är backpackerresor. Dessa resor karaktäriseras av en enklare reseform där äventyr står i fokus. Backpackerresor är förekommande speciellt hos unga resenärer. Dessa resor medför olika typer av risker för resenären att ta i beaktande, dessutom kan det uppmärksammas att kvinnor generellt sett utsätts för många risker. Målet med denna studie var därför att undersöka riskuppfattningen hos unga kvinnliga backpackers. Denna studie genomfördes med en kvalitativ metod baserad på 15 semistrukturerade intervjuer. Resultaten antyder att riskuppfattning har en stor påverkan på valet av destination hos kvinnliga resenärer. Till följd av detta tenderar vissa destinationer att väljas bort på grund av de höga uppfattade riskerna. Dessutom kan en variation inom riskuppfattningen noteras över tid i samband med beslutsprocessen. Inför resan uppfattades en hög riskuppfattning som sedan minskade under resan. Följaktligen uppmärksammades återigen en ökad riskuppfattning efter resan.

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.

The frequency and severity of floods have increased due to climate change and achieving successful disaster risk reduction is deemed crucial to attain preparedness and sustainability. The responsibility for society’s preparedness mainly resides with local public actors. However, several Swedish municipalities have insufficient flood risk management. Research within disaster risk reduction suggests that risk can be understood as socially constructed and produced, highlighting the relevance of exploring risk perceptions. Yet, previous research has mostly been concerned with objective dimensions of risk and largely neglected social dimensions, such as decision-makers’ risk perceptions. Ridolfi and colleagues’ theoretical contribution to Cultural Theory of Risk suggests four types of ideal societies, or perceptions, which ultimately affect flood risk management: risk neglecting, risk monitoring, risk downplaying, and risk controlling perceptions. Yet, the theoretical work has not been applied empirically. This study aims to contribute to a deeper understanding of local public actors’ perceptions of flood risk and how this in turn may be connected to different flood risk management strategies. This thesis adopts a comparative case study design and explores the topic by applying Ridolfi and colleagues’ theoretical contribution to the municipalities of Karlstad and Kristinehamn. While Kristinehamn has been criticized for insufficient flood risk management, Karlstad has been put forward as a front runner in disaster risk reduction. Surprisingly, the results show that the municipalities reason in similar ways about flood risk, suggesting that the proposed differences between the two may be overestimated. Both municipalities believe in the capacity of technical hard-adaptive measures manipulating the environment and thus largely correspond to the risk controlling perception. However, the municipalities differ in some respects, as it can be argued that Karlstad shows signs of a risk monitoring perception whereas Kristinehamn shows signs of a risk neglecting or downplaying perception, potentially shedding light on the slightly varying approaches. In essence, the study’s utilization of the theory indicates that decision-makers’ subjective risk perceptions are important to explore in order to understand flood risk management approaches and subsequently important processes to achieve overall preparedness and sustainability. By exploring municipal actors’ perceptions of flood risk, the study not only contributes empirically by applying mentioned theoretical contribution for the first time, but also adds to the wider body of the theoretical knowledge on the significance of decision-makers’ risk perception for risk reduction, and thus contributes to a better understanding of the social dimensions of risk.

Climate change mitigation requires changes in greenhouse gas emitting behaviours. This dissertation aims to provide insights into the influences of behaviour change for two high-impact pro-environmental behaviours: climate policy support and consumption of animal products. It does so by using quasi- and randomized experiments and by monitoring changes in behaviour over time. Study 1 examined changes in climate policy support and climate change risk perception over the course of a naturally occurring event: seasonal forest fires. It employed growth curve modeling techniques in a structural equation modeling framework to analyze longitudinal relations between these two constructs over time, and to examine growth in climate change risk perception while controlling for the effect of exposure to forest fires and other extreme weather. Indirect exposure to forest fires (e.g., media) had a modest effect on climate change risk perception. Climate change risk perception for individuals with above-mean perceptions of scientific agreement tended to increase faster than for those with below-mean perceptions. Individuals whose climate change risk perception grew at a faster-than-average rate tended to also grow at a faster-than-average rate for climate policy support. Study 2 provided insight into the psychological influences on consumption of animal products and on willingness to reduce. Following a comprehensive literature review, known influences were examined using Latent Profile Analysis to identify groups of individuals with similar perceptions of facilitators of meat consumption and obstacles to reducing it. Three groups were identified: strong-hindrance meat eaters, moderate-hindrance meat eaters, and reducers. Validation variables confirmed the practicality of the three profiles: groups differed in their current consumption of animal products and in their willingness to reduce. Using these findings, three group-matched interventions were designed in Study 3. Intervention design was informed by four behaviour-change frameworks. Participants were randomly assigned to one of four conditions: control condition, implementation-intention condition, information-and-healthy-recipe condition, and information-and-substitution condition. Then, they completed up to 28 days of food diaries. Multilevel model analyses were employed to examine changes in the consumption of animal products over time. Participants reduced their consumption by 20 grams of CO2 per day on average. Individuals that were randomly assigned to an intervention condition that matched their meat-eater profile reduced their consumption of animal products by 40 grams CO2 per day on average. Taken together, these studies highlight the importance of considering individual differences (i.e., tailoring) when designing pro-environmental behaviour interventions. / Graduate

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
