Communicating astrobiology in public: A study of scientific literacy

Oliver, Carol Ann, Biotechnology & Biomolecular Sciences, Faculty of Science, UNSW January 2008 (has links)
The majority of adults in the US and in Europe appear to be scientifically illiterate. This has not changed in more than half a century. It is unknown whether the Australian public is also scientifically illiterate because no similar testing is done here. Public scientific illiteracy remains in spite of improvements in science education, innovative approaches to public outreach, the encouraging of science communication via the mass media, and the advent of the Internet. Why is it that there has been so little change? Is school science education inadequate? Does something happen between leaving high school education and becoming an adult? Does Australia suffer from the same apparent malady? The pilot study at the heart of this thesis tests a total of 692 Year Ten (16-year-old) Australian students across ten high schools and a first year university class in 2005 and 2006, using measures applied to adults. Twenty-six percent of those tested participated in a related scientific literacy project utilising in-person visits to Macquarie University in both years. A small group of the students (64) tested in 2005 were considered the best science students in seven of the ten high schools. Results indicate that no more than 20% of even the best high school science students - on the point of being able to end their formal science education - are scientifically literate if measured by adult standards. Another pilot test among 150 first year university students supports that indication. This compares to a scientific literacy rate of 28% for the US public. This thesis finds that the scientific literacy enterprise ?? in all its forms ?? fails scrutiny. Either we believe our best science students are leaving high school scientifically illiterate or there is something fundamentally wrong in our perceptions of public scientific illiteracy. This pilot study ?? probably the first of its kind ?? indicates we cannot rely on our current perceptions of a scientifically illiterate public. It demonstrates that a paradigm shift in our thinking is required about what scientific literacy is and in our expectations of a scientifically literate adult public. In the worst case scenario, governments are pouring millions of dollars into science education and public outreach with little or no basis for understanding whether either is effective. That is illogical, even irresponsible. It also impacts on the way astrobiology ?? or any science ?? is communicated in public.

To MMR or not MMR: Medical Discourses Surrounding Parental Decision-making for Pediatric Immunization

Shao, Jen-Yin 25 August 2011 (has links)
Coverage for the combined measles, mumps, and rubella vaccine (MMR) has been low since the publication of Wakefield’s 1998 study associating MMR with the onset of autism. As a part of a larger project on risk communication, this study examined the medical discourse on parental decision-making for childhood immunizations to gain insight on why risk communication efforts have not been successful at improving uptake. The Public Understanding of Science (PUS) was used as a theoretical lens to guide Critical Discourse Analysis of texts from medical, pediatric, and public health journals, from which the analytic themes of Risk and Trust emerged. MMR uptake was framed mainly in terms of risk, indicating the dominance of the Deficit Model of PUS in the discourse. Future research and risk communication need to expand beyond current notions of risk; the Contextual Model of PUS can help highlight other factors that impact parental decision-making about MMR.

Media Sensationalism and its Implications on the Public Understanding of Science

Barsoum, Christopher 01 December 2014 (has links)
Myths, misinformation, and sensationalism. These are common enemies that directly inhibit the public understanding of science. In particular, the media is often responsible for mishandling or otherwise misrepresenting scientific information, historically and presently speaking. Many sources can combat the public understanding of science through pseudoscientific means. This includes but is not limited to religion, the media, politics, or just simple hearsay. For example, Young Earth creationism is deeply rooted in Christian theology, but the beliefs hold no scientific basis. Yet, almost half of Americans still believe in Young Earth creationism. Another such example is anti-vaccination campaigns due to fears of autism-spectrum related disorders. In this case, falsified claims were given illegitimate credibility through the media, and the claims are widely and erroneously contentious to this day. The purpose of this research was to investigate the relationship between an individual's ability to dictate science from pseudoscience and their exposure to sensationalized media. Through means of surveying the university level population, relationships were drawn between how many pseudoscientific beliefs an individual may have versus how they interact with science and the media. The results of the survey showed a general lack of interest or care for science with more pseudoscientific beliefs, yet failed to draw a relationship between pseudoscientific beliefs and a sensationalized media.

A Discourse Analysis of Stakeholders? Understandings of Science in Salmon Recovery Policy

White, Dave D. 03 July 2002 (has links)
The purposes of this study were to examine 1) understandings of science expressed in formal salmon recovery policy discourse; 2) rhetorical practices employed to justify or undermine claims about salmon policy 3); and patterns of understandings of science and associated rhetorical practices between social categories of actors. This research contributes to scholarship in public understanding of science, discourse studies, and natural resource policy. A constructivist discourse analysis was conducted using qualitative methods to analyze transcripts from over one hundred congressional hearing witnesses representing a wide diversity of stakeholder groups. Multiple coders organized discourses into analytic categories, achieving a final proportional agreement of 80% or greater for each category, at the finest scale of analysis. Stakeholders employed a collection of prototypical understandings of the nature of science, boundaries of science, and roles of science in decision-making. The process of science was described as impartial and ideal, a way to reduce uncertainty through consensus and peer-review, and subject to changing paradigms. Scientific knowledge was sometimes represented as "truth" and other times as tentative, and scientists were portrayed as independent and objective as well as captured and interest-driven. Witnesses described science as separate from and superior to politics and management. Testimony included descriptions of science?s role in developing decision alternatives, selecting among alternatives, and evaluating and legitimating alternatives. Stakeholders used these understandings of science to construct justifications to support their claims about salmon policy and undermine opposing claims. Science-based justifications included externalizing devices, construction of consensus, category entitlement, and extreme case formulations. Other justifications invoked local control, treaty rights, and local knowledge, or relied on interest management. This study has extended the theory and method of empirical discourse analysis, and produced a taxonomy of understandings that should be transferable to studies of similar policy settings. Additionally, conclusions from this study about differences between social groups in the presence, distribution, and frequency of expression of the discourses might be developed into propositions for further testing. Finally, the study has implications for communication about the role of science in collaborative natural resource decision-making processes. / Ph. D.

Constructing and fracturing alliances : actant stories and the Australian xenotransplantation network

Cook, Peta S. January 2008 (has links)
Xenotransplantation (XTP; animal-to-human transplantation) is a controversial technology of contemporary scientific, medical, ethical and social debate in Australia and internationally. The complexities of XTP encompass immunology, immunosuppression, physiology, technology (genetic engineering and cloning), microbiology, and animal/human relations. As a result of these controversies, the National Health and Medical Research Council (NHMRC), Australia, formed the Xenotransplantation Working Party (XWP) in 2001. The XWP was designed to advise the NHMRC on XTP, if and how it should proceed in Australia, and to provide draft regulatory guidelines. During the period 2001-2004, the XWP produced three publicly available documents one of which, ‘Animal-to-Human Transplantation Research: A Guide for the Community’ (2003), was specifically designed to introduce the general public to the major issues and background of XTP. This thesis examines XTP in Australia as guided and influenced by this community document. Explicitly, drawing upon actor (actant)- network theory, I will reveal the Australian XTP network and explore, describe and explain XTP problematisations and network negotiations by the enrolled actants on two key concepts and obligatory passage points - animals and risk. These actants include those providing regulatory advice (members of the XWP and the associated Animal Issues Subcommittee), those developing and/or critiquing XTP (official science and scientists), and those targeted by the technology (people on dialysis, with Type-1 diabetes, Huntington’s disease, Parkinson’s disease, pre-or post-human-tohuman transplantation, and their partner/spouse). The stories are gathered through focus groups, semi-structured interviews and document analysis. They reveal ambiguous and sometimes contradictory stories about animals and risk, which influence and impact the problematisations of XTP and its networks. Therefore, XTP mobilises tension; facilitating both support and apprehension of the XTP network and its construction by both the sciences and the publics.

Making Bodies Commensurate: The Social Construction of Humans, Animals, and Microbes as Objects of Scientific Study

Kelly, Kimberly Lynn January 2016 (has links)
This dissertation utilizes three independent research projects to examine one overarching theoretical question: How do people understand, contest, negotiate, and / or rationalize the ways in which bodies-human, animal, and microbial - are socially constructed as commensurate, or not, in science? Using three unique projects focusing on either the human, animal, or microbial body, this dissertation broadly explores the social processes inherent in the construction of "bodies" for scientific research. This dissertation explores the complexity of how bodies are used in science, how this is understood by individuals, and the impacts this has not only on science but also the intertwined lives of animals, humans, and their microbes. Each paper explores a key set of questions drawing from a shared set of theoretical lenses, including local biology and biolooping, commensuration, the biovalue of bodies, and the microbiome. Specifically this dissertation presentation will explore these questions: 1) How are Japanese bodies socially constructed as different from other bodies in ethnobridging clinical trials?; 2) How is local biology employed as a technique of commensuration at the site of the Japanese body, by the government, and the global pharmaceutical industry and what does this mean for scientific studies utilizing it in this way?; 3) How do scientists construct nonhuman primates as appropriate proxies for humans in biomedical research experiments?; 4) How do individuals understand themselves and their health in relation to pet dogs and microbes?; and 5) How do humans understand the ways in which humans, animals, and microbes co-create their biological and social worlds? This dissertation shows how the construction of the body as an object of scientific study is negotiated, contested, and taken up in daily life, and how this is flexible, malleable, and not at all uniform. It explores the ways in which biomedical knowledge of the body is socially constructed and how it co-creates the animal, microbial, environmental, and cultural worlds in which it circulates. Through doing so and using techniques and lenses grounded in biosocial anthropology, this dissertation adds to the literature on the body in both medical and multispecies anthropology.

Public Policy, discourse and risk: Framing the xenotransplantation debate in New Zealand (1998-2013)

Kuipers, Benjamin Johannes January 2015 (has links)
This thesis focuses on the evolution and framing of xenotransplantation (XTP) policy debate in New Zealand from 1998 to 2011. Its aim is providing a better understanding of both the science-society interface and the importance of issue framing policy debate in understanding of the scientific debate in New Zealand and its relationship with the public. A qualitative study, this thesis draws upon a variety of public science commentary and debate and poses the research question: How did xenotransplantation’s introduction and explanation to the New Zealand public inform its current status as a Restricted Procedure under New Zealand law; and what ethical implications arise from this public policy debate for public participation in bio-medical research in New Zealand?
