Supermarket tabloids present, as truthful, stories about biomedical science that are greatly exaggerated and often fictitious. Apparently a sizable portion of their large readership accepts these stories as correct. This is “scientific journalism” at its worst, but its standards are not wholly different from those of the mainline press. Allan Mazur is both a sociologist and a technologist. He received an M.S. in Engineering from UCLA and worked for several years as an aerospace engineer before obtaining a Ph.D. in sociology from Johns Hopkins University. He has been a member of the social science faculties of MIT and Stanford University, and is currently a professor in Syracuse University's Maxwell School of Citizenship and Public Affairs.The Dynamics of Technical Controversy (1981) is his major work on public disputes over technology, and he continues to work in this area as well as in biosociology.  相似文献

The authors discuss the history of research terminology in American psychology with respect to the various labels given to those upon whom we conduct research (“observer”–“subject”–“participant”–“client”). This history is supplemented with an analysis of participant terminology in APA manuals from four historical eras, from the 1950s to the present. The general trend in participant terminology reflects the overall trends in American psychology, beginning with a complex lexicon that admitted both the passive and the active research participant, followed by a dominance of the passive term ‘subject’ and ending with the terminological ambiguity and multiplicity reflected in contemporary psychology. This selective history serves to contextualize a discussion of the meaning, functions, and implications of the transformations in, and debates over, participant terminology.

This essay juxtaposes concepts created by Gilles Deleuze and Félix Guattari with worlds imagined by Ursula Le Guin in a performance of ‘rhizosemiotic play’ that explores some possible ways of generating and sustaining what William Pinar calls ‘complicated conversation’ within the regime of signs that constitutes an increasingly internationalized curriculum field. Deleuze and Guattari analyze thinking as flows or movements across space. They argue, for example, that every mode of intellectual inquiry needs to account for the plane of immanence upon which it operates—the preconceptual field presupposed by the concepts that inquiry creates. Curriculum inquiry currently operates on numerous nationally distinctive planes of immanence. I argue that the internationalization of curriculum studies should not presume a singular transnational plane of immanence but, rather, envisage a process performed by curriculum scholars with the capacities and competencies to change planes—to move between one plane of immanence and another and/or to transform their own planes. My essay is a ‘narrative experiment’ that takes seriously Deleuze’s argument that a work of philosophy should be, in part, a kind of science fiction, and also takes inspiration from Le Guin’s science fictional stories of ‘changing planes’ to generate productive and disruptive transnational agendas in curriculum inquiry.

Futurists have imagined the Internet as a separate “cyberspace” and as a force for an idealized marketplace. Business practice and economic theory, however, lead to a different picture. (1) “Always-on” connections bring new interface problems and social skills. (2) Reduced transaction costs and increased economies of scale bring outsourcing, concentration, and globalized economy of focused monopolies. (3) The economies of scope inherent in modular computing systems bring “shallow diversity”: processes and products generated by a common underlying framework. This new picture omits many countervailing factors. Even so, the very existence of alternative scenarios should sharpen questions for research. He received his Ph.D. in computer science from MIT in 1989, having conducted dissertation research in the Artificial Intelligence Laboratory on computational models of improvised activities.

Advocates of many different approaches have, for years, attempted to usurp cognitive psychology’s dominance in the field of psychology. Unfortunately, none of these approaches have yet made a convincing case that they could take cognitive psychology’s place. Because of its explicit use of the mind-as-computer model, cognitivism gains a false sense of concreteness, and becomes pragmatically useful. Because their models are implicit, alternatives, such as phenomenology, gain a false sense of ambiguity and lose their pragmatic potential. In addition, alternative theories often alienate potential sympathizers through unnecessarily harsh criticism. This leads to a professional attitude in which one must take sides, rather than an attitude that appreciates the benefits of diversity, and may lead to the emergence of other beneficial models. If alternative approaches, such as Dr. Flores-González’s (Integrative Psychological and Behavioral Sciences, 2008), could push through to the point of immediate usefulness, and present themselves in a less adversarial way, they would be much better placed make meaningful contributions.

Teaching ethics in engineering and computer science: A panel discussion   总被引:1,自引:0,他引:1  
At a conference, two engineering professors and a philosophy professor discussed the teaching of ethics in engineering and computer science. The panelists considered the integration of material on ethics into technical courses, the role of ethical theory in teaching applied ethics, the relationship between cases and codes of ethics, the enlisting of support of engineering faculty, the background needed to teach ethics, and the assessment of student outcomes. Several audience members contributed comments, particularly on teaching ethical theory and on student assessment. This panel discussion took place at a mini-conference, Practicing and Teaching Ethics in Engineering and Computing, held during the Sixth Annual Meeting of the Association for Practical and Professional Ethics, Washington, D.C., March 8–9, 1997. Biographical information on panelists: Charles Glagola is an assistant professor of civil engineering at the University of Florida. He is a registered professional engineer in the states of Florida and Alabama. Before coming to academia, he had extensive industry experience culminating with his owning and operating a construction and engineering firm in Pensacola, Florida. He currently teaches engineering ethics as part of a professional issues course in the Department of Civil Engineering, and a one-hour engineering ethics course that is offered to all engineering students through the College of Engineering. Moshe Kam is professor of electrical and computer engineering at Drexel University. He heads Drexel’s Data Fusion Laboratory which specializes in multisensor systems and robot navigation. His professional interests include detection and estimation, distributed decision making, forensic applications of image processing, and engineering ethics. Michael Loui is professor of electrical and computer engineering and associate dean of the Graduate College at the University of Illinois at Urbana-Champaign. From 1990 to 1991, he served at the National Science Foundation in Washington, D.C. His scholarly interests include computational complexity theory, theory of parallel and distributed computation, fault-tolerant software, and professional ethics. Caroline Whitbeck is a philosopher of science, technology and medicine and is the Elmer G. Beamer-Hubert H. Shneider Professor in Ethics at Case-Western Reserve University. She also directs the WWW Ethics Center for Engineering & Science— http://ethics.cwru.edu— under a grant from the National Science Foundation.

The original concept of “social physics” was built on positivist philosophy and scientific method. Evidence from quantum physics suggests that a postpositivist “social physics” may yet be viable, not because social science should emulate physics, but because physics is more like social science. The five principles of complementarty, uncertainty, the measurement problem, nonlocal causation, and participatory collusion are presented in this article to demonstrate the contemporary convergence of the physical and social sciences into a new social physics. E. Sam Overman is associate professor of public affairs at the Graduate School of Public Affairs, University of Colorado at Denver, Denver CO 80204. He recently editedMethodology and Epistemology for Social Science, selected papers by Donald T. Campbell (University of Chicago Press, 1988). He has published other articles on policy physics and social science philosophy, and has conducted research and published extensively in the area of information resource policy and management.  相似文献

Complexity theories are on the way to establish a new worldview—processes instead of objects, history and uniqueness of everything instead of repetition and lawlikeness are the elements. These theories from deterministic chaos via the dissipative structures, the theory of catastrophes, self organization and synergetics are mathematical models, connected with a new understanding of science. They are characterized by new fundamental commitments of sciences. But at the same time, they are characterized by epistemic boundaries. During my stay as a visiting professor at Dalian University of Technology in September 2006, I had the opportunity to deliver parts of this paper at North-Eastern University at Shenyang and at Beijing Normal University; a first draft has been presented at the IV. Russian Congress of Philosophy, May 2005, Moscow, and published as congress material as Knowledge and Society, edited by Ilya Kassavine, Moscow: Kanon 2005, 178–189.  相似文献

Knowledge must forever govern ignorance, and a people who would be their own governors must arm themselves with the power which knowledge gives.

On the basis of personal reminiscences an account is given of Harlow’s role in the development of attachment theory and key notions of attachment theory are being discussed. Among other things, it is related how Harlow arrived at his famous research with rhesus monkeys and how this made Harlow a highly relevant figure for attachment theorist Bowlby.

This article reviews and criticizes the recent writing of Charles Gerkin (Living Human Document, 1984;Widening the Horizons, 1986). Gerkin is concerned to ground the practice of ministry in the Judeo-Christian Tradition in a world of pluralistic claims to meaning. He calls his approach a narrative hermeneutical perspective, and shows in case material how the stories of individuals and groups can be reinterpreted through the work of ministry. Poling examines Gerkin's work to see what views of human nature and God are operative here. The result is a dialogue about the nature of pastoral theology and its role in the church today.  相似文献

No one can access the original events to examine the veracity of a human experience in everyday situations. The present experiment was done to compare two conditions under which a participant remembered (1) her actual contact with the environment and (2) her indirect experience—information about another person’s direct experience that was communicated to her. Several differences in the forms of remembering such as narrative styles, way of describing and naming of object, motive for actions—were found to differ between those two conditions. Those differences were shown to disappear with repeated remembering occasions due to intrapersonal and interpersonal conventionalization. These results suggest that it is possible to examine the veracity of an experience based on forms of remembering, rather than on its content. Theoretical discussion links the present experiment to the study of memory and remembering from the perspective of Bartlett’s (Remembering: A study in experimental and social psychology. Cambridge: Cambridge University Press, 1932) schema theory.

Conclusion Robert Heinlein, author of Stranger in a Strange Land as well as countless other science fiction stories, once claimed that "The sole thing achieved by any privacy law is to make the bugs smaller." Heinlein may be correct, but that travesties will happen does not sanction them—and maybe we will invent bugs to root out and foil other bugs. I have argued for individual privacy rights or rights to control sensitive personal information. The explosion of digital technology has made possible severe violations of individual privacy by corporations, news agencies, and the government. If I am correct about all of this, one commonly used "public interest" argument given for limiting privacy rights has been undermined. It is also far from true to claim that the prevalence of strong encryption technology will lead to disaster. While I do not adhere to the view that "rights hold, though the heavens may fall," in this article I have maintained that the security arguments of law enforcement do not come close to meeting the threshold for violating privacy rights. The heavens are far from falling.

From 1957 through the mid-1970s, John Bowlby, one of the founders of attachment theory, was in close personal and scientific contact with Harry Harlow. In constructing his new theory on the nature of the bond between children and their caregivers, Bowlby profited highly from Harlow’s experimental work with rhesus monkeys. Harlow in his turn was influenced and inspired by Bowlby’s new thinking. On the basis of the correspondence between Harlow and Bowlby, their mutual participation in scientific meetings, archival materials, and an analysis of their scholarly writings, both the personal relationship between John Bowlby and Harry Harlow and the cross-fertilization of their work are described.

As Ecological Psychology pushes into new areas, success will be made easier by a rediscovery its theoretical history, in particular the “New Realism”, lead in part by E. B. Holt. Three New Realists tenants seem particularly relevant: (1) we experience reality, (2) relations are real, and (3) things are what you see when you see those things. Though the two groups differ in terms of their conception of perception, and what can be perceived, their conceptions are related in very insightful ways. Further, the comparison reemphasizes the extent of unique empirical claims ecological psychologists make, and grounds those claims within a larger framework for psychology as a whole. This makes obvious the need for further work on the mathematics of invariants, the physiological mechanisms of information extraction, and the behaviors of perception.

This work presents a semiotic approach to the economy, underlining that any economic phenomena is at the same time a communicative act as it is contingent to sense-making.The article discusses this topic by focusing on a specific phenomenon studied by economics: the underground economy. It shows that the conceptualization of the underground economy in terms of sense-making processes offers a thought-provoking perspective for theoretical development. More in general, the discussion proposed makes it clear that in order to deepen our vision of economic phenomena in a more thoughtful and realistic way we need to rethink these phenomena as being reciprocally and circularly embedded in the semiotic flow of life. The economy is within sense-making and it is shaped by it; at the same time sense-making is within the economy, as its semiotic substance.

This special issue includes seven articles that make significant contribution to the literature pertaining to knowledge and public policy around Free, Libre and Open Source Software (FLOSS). Focusing on questions in two themes (i) motivation and organization and (ii) public policy, the articles in this volume develop new analytic models and report on new empirical findings, as an important step in bridging the wide gap that exists in public policy literature around FLOSS. Warning against rhetorical pitfalls that have been prevalent in FLOSS research, this introduction starts with a short history of FLOSS development, continues with a brief thematic literature review and review of the misconceptions surrounding FLOSS, and concludes with a first introduction of the articles that follow. He is part of the Dutch Institute of Government (NIG), the research school for public administration and political science. His research focuses on the organization of open source communities. He received two grants from the Netherlands Organization for Scientific Research (NWO) for research related to open source communities. The first grant was to study the interplay between intellectual property rights and open source communities. The results are published in Governing the Virtual Commons (Cambridge University Press, 2003). He has written numerous articles on open source, which have appeared in journals like Electronic Markets; Knowledge, Technology and Policy; and the International Journal of IT Standards & Standardisation Research. She received her Ph.D. in sociology from the University of York (UK) in 2004. Her Ph.D. research investigated the heterogeneity and contingency in the Free, Libre Open Source Software (FLOSS) social worlds, which is based on a constellation of hacking practices, from the sociological perspective. Her principal research interests center on FLOSS studies, Science and Technology Studies (STS), virtual communities and knowledge-sharing. Shay is also a fellow at The Information Society Project at the Yale Law School. Shay holds a B.Sc. in computer science and a B.A. in philosophy, magna cum laude, from Tel-Aviv University, and an M.A. from New York University where his interdisciplinary research thesis focused on the political economy of free and open source software and file sharing networks.

Since the new beginning in 2007 of Integrative Psychological & Behavioral Science we have brought out to the open both the reasons why the ever-widening research enterprise in psychology has largely failed to produce general knowledge, and to point to promising new directions in the field. The post-modernist turn in psychology is now over, and it is an interesting task to return to creating a universal science of psychology that is context-sensitive, and culture-inclusive. The latter goal entails a renewed focus upon qualitative analyses of time-based processes, close attention to the phenomena under study, and systematic (single-system-based—usually labeled idiographic) focus in empirical investigations. Through these three pathways centrality of human experiencing of culturally constructed worlds is restored as the core of psychological science. Universal principles are evident in each and every single case. Transcending post-modernist deconstruction of science happens through active international participation and a renewed focus on creating general theories. Contemporary psychology is global in ways that no longer can any country’s socio-political world view dominate the field. Such international equality of contributions grants innovation of the core of the discipline, and safeguards it against assuming any single cultural myth-story as the axiomatic basis for the discipline.

In this contribution, the authors give an overview of the different studies on the effect of separation and deprivation that drew the attention of many in the 1940s and 1950s. Both Harlow and Bowlby were exposed to and influenced by these different studies on the so called ‘hospitalization’ effect. The work of Bakwin, Goldfarb, Spitz, and others is discussed and attention is drawn to films that were used to support new ideas on the effects of maternal deprivation.

The Logic of Knowledge Based Obligation   总被引:1,自引:0,他引:1  
Deontic Logic goes back to Ernst Mally’s 1926 work, Grundgesetze des Sollens: Elemente der Logik des Willens [Mally. E.: 1926, Grundgesetze des Sollens: Elemente der Logik des Willens, Leuschner & Lubensky, Graz], where he presented axioms for the notion ‘p ought to be the case’. Some difficulties were found in Mally’s axioms, and the field has much developed. Logic of Knowledge goes back to Hintikka’s work Knowledge and Belief [Hintikka, J.: 1962, Knowledge and Belief: An Introduction to the Logic of the Two Notions, Cornell University Press] in which he proposed formal logics of knowledge and belief. This field has also developed quite a great deal and is now the subject of the TARK conferences. However, there has been relatively little work combining the two notions of knowledge (belief) with the notion of obligation. (See, however, [Lomuscio, A. and Sergot, M.: 2003, Studia Logica 75 63–92; Moore, R. C.: 1990, In J. F. Allen, J. Hendler and A. Tate (eds.), Readings in Planning, Morgan Kaufmann Publishers, San Mateo, CA]) In this paper we point out that an agent’s obligations are often dependent on what the agent knows, and indeed one cannot reasonably be expected to respond to a problem if one is not aware of its existence. For instance, a doctor cannot be expected to treat a patient unless she is aware of the fact that he is sick, and this creates a secondary obligation on the patient or someone else to inform the doctor of his situation. In other words, many obligations are situation dependent, and only apply in the presence of the relevant information. Thus a case for combining Deontic Logic with the Logic of Knowledge is clear. We introduce the notion of knowledge based obligation and offer an S5, history based Kripke semantics to express this notion, as this semantics enables us to represent how information is transmitted among agents and how knowledge changes over time as a result of communications. We consider both the case of an absolute obligation (although dependent on information) as well as the (defeasible) notion of an obligation which may be over-ridden by more relevant information. For instance a physician who is about to inject a patient with drug d may find out that the patient is allergic to d and that she should use d′ instead. Dealing with the second kind of case requires a resort to non-monotonic reasoning and the notion of justified belief which is stronger than plain belief, but weaker than absolute knowledge in that it can be over-ridden. This notion of justified belief also creates a derived notion of default obligation where an agent has, as far as the agent knows, an obligation to do some action a. A dramatic application of this notion is our analysis of the Kitty Genovese case where, in 1964, a young woman was stabbed to death while 38 neighbours watched from their windows but did nothing. The reason was not indifference, but none of the neighbours had even a default obligation to act, even though, as a group, they did have an obligation to take some action to protect Kitty. Earlier versions of this paper were presented at the conferences SEP-2004, and DALT-2004.  相似文献
