Perspectives on Science and Culture Comparative Cultural Studies Ari Ofengenden, Series Editor The series examines how cultural practices, especially contemporary creative media, both shape and themselves are shaped by current global developments such as the digitization of culture, virtual reality, global interconnectedness, increased people flows, transhumanism, environmental degradation, and new forms of subjectivi- ties. We aim to publish manuscripts that cross disciplines and national borders in order to provide deep insights into these issues.

The contributions in this volume analyze pop- ular representations of science and scientific discourse from the perspectives of rhetorical criticism, comparative cultural studies, narratology, educational stud- ies, discourse analysis, the cognitive sciences, and naturalized and evolutionary epistemology. As such, the volume fits within the theoretical and methodolog- ical framework of comparative cultural studies as a contextual approach to the study of culture from an interdisciplinary perspective. The main objective of this volume is to explore how particular cognitive predispositions and cultural representations both shape and distort the public debate about scientific con- troversies, the teaching and learning of science, and the development of science itself. Theoretically, this volume will integrate, on the one hand, C. P. Snow’s concept of the two cultures (science versus the humanities) and Jerome Bruner’s confrontation between narrative and logico-scientific modes of thinking and, on the other hand, cognitive and epistemological approaches to human cognition and culture, including science. From this unique conciliatory framework, the volume explores how narra- tives and other cultural representations transform complex scientific issues into digestible bits of information based on particular selections and deflections. Some of the contributions analyze how scientific representations and metaphors of science take shape in pictures, cartoons, and television broadcasts, but also in novels and popular magazines. Others specifically focus on the implications of these representations and (mis)understandings for science education, both in ix x Introduction formal and informal educational settings. Thematically, the contributions focus on a wide range of current debates about evolutionary theory, global warming, genetic modification, and so on. As such, it indirectly engages with discussions pertaining to the politics of science. The aim of this volume is to engage in the ongoing debate about the public understanding of science and is original in its interdisciplinary scope, ranging from philosophy, cognitive psychology, anthro- pology, and biology to literature, cultural studies, and rhetoric. Public Understanding of Science There has been increasing attention on the valorization of scientific research, in combination with a growing public debate about the uses and applications of sci- entific findings for social and economic purposes (Benneworth and Jongbloed). Media coverage of scientific findings plays an important role in shaping the public understanding of science and as such creates a context for socio-ethical debates about the application and development of scientific research (van Dijck). However, the communication of science is always, inevitably partial and this partiality raises issues of authority, creates potential misunderstandings, and complicates the public debate about science (Tietge). One of the main aims of science communication and programs aimed at increasing scientific literacy is to create a better public understanding of science and to emphasize its wider rele- vance to society (Gross, “Roles”). Science communication often consists of a one-way flow from scientists to the general public by accommodating scientific findings to a nonexpert audience. Such a unilateral approach is indeed important for transferring relevant scientific knowledge to society but runs the risk of disregarding the contexts that give sci- ence its public significance and the ambiguities that arise from particular framings in the public debate (Gross, “Roles” and Rhetoric). Public concerns and opinions from stakeholders are often seen as (unwarranted) anxieties or vested interests rather than “assets” that have a role to play in the debate about scientific develop- ments and applications (Bauer; Bauer, Shukla and Allum). There is an entangled and reciprocal relationship between science and society and therefore there is a need for a better understanding of the accommodation of scientific findings from experts to lay audiences, for an understanding of the different positions in the sci- entific and the public debate, and for an integration of scientific developments and the needs of society (Fahnestock; Gross, “Roles” and Rhetoric; Tietge, Rational). For example, there is an ongoing body of research on the public under- standing of genetics. Although there have been vast scientific advances in DNA Perspectives on Science and Culture xi technology, the socio-ethical and the legal and political debates still remain very contested and ambivalent. In her seminal work, Imagenation, José van Dijck has shown that the public imagination of genetics has undergone an important trans- formation during the decades that this branch of scientific research took shape, as the synopsis of her

  • The Two Cultures of Undergraduate Academic Engagement
    Res High Educ DOI 10.1007/s11162-008-9090-y The Two Cultures of Undergraduate Academic Engagement Steven Brint Æ Allison M. Cantwell Æ Robert A. Hanneman Received: 11 June 2007 Ó Springer Science+Business Media, LLC 2008 Abstract Using data on upper-division students in the University of California system, we show that two distinct cultures of engagement exist on campus. The culture of engagement in the arts, humanities and social sciences focuses on interaction, participation, and interest in ideas. The culture of engagement in the natural sciences and engineering focuses on improvement of quantitative skills through collaborative study with an eye to rewards in the labor market. The two cultures of engagement are strongly associated with post-graduate degree plans. The findings raise questions about normative conceptions of good educational practices in so far as they are considered to be equally relevant to students in all higher education institutions and all major fields of study. Keywords Academic engagement Á Student cultures Á Research universities Á Graduate degree aspirations Considerable scholarly and policy attention has been directed toward the improvement of undergraduate education for more than two decades (see, e.g., AAC 1985; Chickering and Gamson 1987). Yet interest appears to have peaked in recent years, as indicated by large- scale improvement efforts at many of the country’s leading research universities (see, e.g., Rimer 2007). The most important cause of this heightened interest is the report of the Secretary of Education’s Commission on the Future of Higher Education (also known as the Spellings Commission). The Spellings Commission proposed incentives for the adoption of stan- dardized testing for purposes of making higher education accountable to consumers.

  • The “Two Cultures” in Clinical Psychology: Constructing Disciplinary Divides in the Management of Mental Retardation
    The “Two Cultures” in Clinical Psychology: Constructing Disciplinary Divides in the Management of Mental Retardation Andrew J. Hogan Creighton University Isis, Vol. 109, no. 4 (2018): 695-719 In a 1984 article, psychologist Gregory Kimble lamented what he saw as the two distinct cultures of his discipline. Writing in American Psychologist, a prominent professional journal, he noted, “In psychology, these conflicting cultures [scientific and humanistic] exist within a single field, and those who hold opposing values are currently engaged in a bitter family feud.” 1 In making his argument, Kimble explicitly drew upon British scientist and novelist C.P. Snow’s 1959 lecture The Two Cultures, in which Snow expressed concern about a lack of intellectual engagement between scientists and humanists, and about the dominant position of the humanities in British education and culture. Kimble used Snow’s critique to help make sense of what he perceived to be a similar polarizing divide between “scientific” and “humanistic” psychologists. 2 As Kimble described it, humanistic psychologists differed form their scientific colleagues in placing their ambitions to enact certain social policies and to promote particular social values- based ideologies ahead of the need for the scientific validation of these approaches. Kimble demonstrated his purported two cultures divide in psychology using survey data he collected from 164 American Psychological Association (APA) members. Each was part of either APA Division 3 (Experimental Psychology) or one of three other Divisions, which represented special interest groups within the psychology field. His results, illustrated on a spectrum from scientific to humanistic orientation, showed a purported divide between experimental psychologists on the scientific side, and their humanistic colleagues in the other three Divisions (See Figures 1,2).

  • Hwa-Byung:The
    FROM THE INSTRUCTOR In his prize-winning essay, “Hwa-Byung: The “Han”-Blessed Illness,” Wooyoung Cho taps a global skill set to shed new light on how culture shapes definitions of mental illness. His paper is an outstanding example of student-driven inquiry. I had never heard of the Korean culture-bound mental illness called hwa-byung when Wooyoung proposed this project. But even if I had, I would’ve had no idea where to find narratives about hwa-byung written by young men, let alone be able to translate them from Korean. (Are you curious yet?) In his research, Wooyoung learned that scholarly studies of hwa-byung have focused on middle-aged women and interpreted their symptoms as reflections of Korea’s patriarchal social structure. When he discovered that today more young men are being diagnosed with hwa-byung, he wanted to understand the social causes of their distress. One way he gathered evidence was by searching a Korean online forum and reading posts by young men about their hwa-byung experiences. When students in Marisa Milanese’s “Global Documentary” class read a draft of Wooyoung’s essay in a cross-section peer review exercise, they were understandably skeptical about his methodology. They asked for “a clearer understanding of why analyzing narratives is a credible method to gain insight into this illness.” Wooyoung responded with a revision that provided the theoretical framework necessary to explain the kind of authority those anonymous online posts have in the context of his project. He was wise to listen carefully to his readers.

  • Ten Misunderstandings About Evolution a Very Brief Guide for the Curious and the Confused by Dr
    Ten Misunderstandings About Evolution A Very Brief Guide for the Curious and the Confused By Dr. Mike Webster, Dept. of Neurobiology and Behavior, Cornell Lab of Ornithology, Cornell University ([email protected]); February 2010 The current debate over evolution and “intelligent design” (ID) is being driven by a relatively small group of individuals who object to the theory of evolution for religious reasons. The debate is fueled, though, by misunderstandings on the part of the American public about what evolutionary biology is and what it says. These misunderstandings are exploited by proponents of ID, intentionally or not, and are often echoed in the media. In this booklet I briefly outline and explain 10 of the most common (and serious) misunderstandings. It is impossible to treat each point thoroughly in this limited space; I encourage you to read further on these topics and also by visiting the websites given on the resource sheet. In addition, I am happy to send a somewhat expanded version of this booklet to anybody who is interested – just send me an email to ask for one! What are the misunderstandings? 1. Evolution is progressive improvement of species Evolution, particularly human evolution, is often pictured in textbooks as a string of organisms marching in single file from “simple” organisms (usually a single celled organism or a monkey) on one side of the page and advancing to “complex” organisms on the opposite side of the page (almost invariably a human being). We have all seen this enduring image and likely have some version of it burned into our brains.

  • "Critical Analysis of Evolution"; Innovative Lesson Plan Or
    THE OHIO DEPARTMENT OF EDUCATION L10H23 “CRITICAL ANALYSIS OF EVOLUTION”; INNOVATIVE LESSON PLAN OR STEALTHY ADVOCACY TOOL? Robert Day, The Ohio State University. Presented at the National Association of Researchers of Science Teaching (NARST) annual conference, San Francisco, CA. April 2006. Abstract: This paper will discuss the ongoing controversy surrounding a particular Ohio Department of Education tenth grade lesson plan titled “Critical Analysis of Evolution” (Ohio Department of Education identification L10H23). The lesson professes to encourage students to “critically examine” evidences for and against evolution and invites them to discuss definitions of some common evolutionary terms and concepts. Proponents insist that this lesson is a thought-provoking exercise in critical thinking and scientific objectively. Critics claim that the lesson is at best, unscientific and at worst, a thinly-veiled attempt to introduce creationist ideas into the classroom in accordance with the so-called “wedge” strategy of certain pro-creationist organizations. A complicating factor is that this lesson plan has been used as the subject of graduate level research on the effect of teaching “the evolution controversy” to Ohio students, and subsequently, this research has been used to support similar initiatives in state hearings outside of Ohio. We will present the findings from a series of surveys conducted with life-science high school teachers, college faculty, and graduate students intended to establish whether or not practicing scientists and science educators agree with the Ohio Board of Education’s assessment that “there is no ID [intelligent design] there”. We will look for trends in the opinions of different sub-populations, identify key differences of opinions between participants and Ohio Board of Education members and suggest possible reasons for any apparent conflicts of opinion.

  • Why Much of What We Teach About Evolution Is Wrong/By Jonathan Wells
    ON SCIENCE OR MYTH? Whymuch of what we teach about evolution is wrong Icons ofEvolution About the Author Jonathan Wells is no stranger to controversy. After spending two years in the U.S. Ar my from 1964 to 1966, he entered the University of California at Berkeley to become a science teacher. When the Army called him back from reser ve status in 1968, he chose to go to prison rather than continue to serve during the Vietnam War. He subsequently earned a Ph.D. in religious studies at Yale University, where he wrote a book about the nineteenth­ century Darwinian controversies. In 1989 he returned to Berkeley to earn a second Ph.D., this time in molecular and cell biology. He is now a senior fellow at Discovery Institute's Center for the Renewal of Science and Culture (www.discovery.org/ crsc) in Seattle, where he lives with his wife, two children, and mother. He still hopes to become a science teacher. Icons ofEvolution Science or Myth? Why Much oJWhat We TeachAbout Evolution Is Wrong JONATHAN WELLS ILLUSTRATED BY JODY F.

  • C.P. Snow the REDE LECTURE, 1959
    C.P. Snow THE REDE LECTURE, 1959 © Cambridge University Press 1 THE TWO CULTURES It is about three years since I made a sketch in print of a problem which had been on my mind for some time. 1 It was a problem I could not avoid just because of the circumstances of my life. The only credentials I had to ruminate on the subject at all came through those circumstances, through nothing more than a set of chances. Anyone with similar experience would have seen much the same things and I think made very much the same comments about them. It just happened to be an unusual experience. By training I was a scientist: by vocation I was a writer. That was all. It was a piece of luck, if you like, that arose through coming from a poor home. But my personal history isn't the point now. All that I need say is that I came to Cambridge and did a bit of research here at a time of major scientific activity. I was privileged to have a ringside view of one of the most wonderful creative periods in all physics. And it happened through the flukes of war— including meeting W. L. Bragg in the buffet on Kettering station on a very cold morning in 1939, which had a determining influence on my practical life—that I was able, and indeed morally forced, to keep that ringside view ever since. So for thirty years I have had to be in touch with scientists not only out of curiosity, but as part of a working existence.

    Journal of Exposure Science and Environmental Epidemiology (2007) 17, 31–38 r 2007 Nature Publishing Group All rights reserved 1559-0631/07/$30.00 www.nature.com/jes Use of portable microbial samplers for estimating inhalation exposure to viable biological agents MAOSHENG YAO AND GEDIMINAS MAINELIS Department of Environmental Sciences, Rutgers, The State University of New Jersey, 14 College Farm Road, New Brunswick, New Jersey 08901-8551, USA Portable microbial samplers are being increasingly used to determine the presence ofmicrobial agents in the air; however, their performance charac teristics when sampling airborne biological agents are largely unknown. In addition, it is unknown whether these samplers could be used to assess microbial inhalation exposure according to the particle sampling conventions. This research analyzed collection efficiencies of MAS-100, Microflow, SMA MicroPortable, Millipore Air Tester, SAS Super 180, BioCulture, and RCS High Flow portable microbial samplers when sampling six bacterial and fungal species ranging from 0.61 to 3.14mm in aerodynamic diameter. The efficiencies with which airborne microorganisms were deposited on samplers’ collection medium were compared to the particle inhalation and lung deposition convention curves. When sampling fungi, RCS High Flow and SAS Super 180 deposited 80%–90% ofairborne spores on agar F highest among investigated samplers. Other samplers showed collection efficiencies of 10%–60%. When collecting bacteria, RCS High Flow and MAS-100 collected 20%–30%, whereas other samplers collected less than 10% ofthese bioparticles. Comparison ofsamplers’ collection efficiencies with particle inhalation convention curves showed that RCS High Flow and SAS Super 18 0 could be used to assess inhalation exposure to particles larger than 2.5 mm, such as fungal spores.
