Recent experiments have been used to “edit” genomes of various plant, animal and other species, including humans, with unprecedented precision. Furthermore, editing the Cas9 endonuclease gene with a gene encoding the desired guide RNA into an organism, adjacent to an altered gene, could create a “gene drive” that could spread a trait through an entire population of organisms. These experiments represent advances along a spectrum of technological abilities that genetic engineers have been working on since the advent of recombinant DNA techniques. The scientific and bioethics communities have built substantial literatures about the ethical and policy implications of genetic engineering, especially in the age of bioterrorism. However, recent CRISPr/Cas experiments have triggered a rehashing of previous policy discussions, suggesting that the scientific community requires guidance on how to think about social responsibility. We propose a framework to enable analysis of social responsibility, using two examples of genetic engineering experiments. 相似文献

In this paper we analyse how the risks associated with research on transgenic plants are regulated in Sweden. The paper outlines
the way in which pilot projects in the plant sciences are overseen in Sweden, and discusses the international and national
background to the current regulatory system. The historical, and hitherto unexplored, reasons for the evolution of current
administrative and legislative procedures in plant science are of particular interest. Specifically, we discuss similarities
and differences in the regulation of medicine and plant science, and we examine the tendency towards dichotomizing risk —
focusing on social/ethical risks in medicine and biological risks in plant science. The context of this article is the Synpraxia
research project, an inter-disciplinary program combining expertise in sciences and the humanities. 相似文献

Continuing advances in human ability to manipulate matter at the atomic and molecular levels (i.e. nanoscale science and engineering)
offer many previously unimagined possibilities for scientific discovery and technological development. Paralleling these advances
in the various science and engineering subdisciplines is the increasing realization that a number of associated social, ethical,
environmental, economic and legal dimensions also need to be explored. An important component of such exploration entails
the identification and analysis of the ways in which current and prospective researchers in these fields conceptualize these
dimensions of their work. Within the context of a National Science Foundation funded Research Experiences for Undergraduates
(REU) program in nanomaterials processing and characterization at the University of Central Florida (2002–2004), here I present
for discussion (i) details of a “nanotechnology ethics” seminar series developed specifically for students participating in
the program, and (ii) an analysis of students’ and participating research faculty’s perspectives concerning social and ethical
issues associated with nanotechnology research. I conclude with a brief discussion of implications presented by these issues
for general scientific literacy and public science education policy. 相似文献

Functional explanation and the function of explanation 总被引:1,自引:0,他引:1
Teleological explanations (TEs) account for the existence or properties of an entity in terms of a function: we have hearts because they pump blood, and telephones for communication. While many teleological explanations seem appropriate, others are clearly not warranted--for example, that rain exists for plants to grow. Five experiments explore the theoretical commitments that underlie teleological explanations. With the analysis of [Wright, L. (1976). Teleological Explanations. Berkeley, CA: University of California Press] from philosophy as a point of departure, we examine in Experiment 1 whether teleological explanations are interpreted causally, and confirm that TEs are only accepted when the function invoked in the explanation played a causal role in bringing about what is being explained. However, we also find that playing a causal role is not sufficient for all participants to accept TEs. Experiment 2 shows that this is not because participants fail to appreciate the causal structure of the scenarios used as stimuli. In Experiments 3-5 we show that the additional requirement for TE acceptance is that the process by which the function played a causal role must be general in the sense of conforming to a predictable pattern. These findings motivate a proposal, Explanation for Export, which suggests that a psychological function of explanation is to highlight information likely to subserve future prediction and intervention. We relate our proposal to normative accounts of explanation from philosophy of science, as well as to claims from psychology and artificial intelligence. 相似文献

Data collected during an evaluation of a multi-site trial of an enhanced after-school program were used to relate quality of program implementation to student experiences after school. The enhanced after-school program incorporated a drug use and violence prevention component that was shown to be effective in previous research. Building on Durlak and Dupre’s (Am J Community Psychol 41:327–350, 2008) dimensions of implementation, we assessed the level of dosage, quality of management and climate, participant responsiveness, and staffing quality achieved at the five program sites. We evaluated how these characteristics co-varied with self-reported positive experiences after-school. The study illustrates how multiple dimensions of program implementation can be measured, and shows that some but not all dimensions of implementation are related to the quality of student after-school experiences. Measures of quality of management and climate, participant responsiveness, and staffing stability were most clearly associated with youth experiences. The importance of measuring multiple dimensions of program implementation in intervention research is discussed. 相似文献

After discussing evidence of irreligion and the rise of the so called “New Atheism”, the authors refute the claim that this poses a problem for the cognitive science of religion and its hypothesis that religion is natural. The “naturalness hypothesis” is not deterministic but probabilistic and thus leaves room for atheism. This, the authors maintain, is true of both the by-product and adaptationist stances within the cognitive science of religion. In this context the authors also discuss the memetic or “unnaturalness” hypothesis, i.e. that religion is a “virus of the mind”. The authors criticize accounts of atheism offered by cognitive scientists of religion as being based on unfounded assumptions about the psychology of atheists, and object to the notion that the natural aspects of religion by corollary make atheism unnatural. By considering human cognition in a semiotic framework and emphasizing its natural ability to take part in semiotic systems of signs, atheism emerges as a natural, cognitive strategy. The authors argue that to reach a fuller account of religion, the cognitive (naturalness) and memetic (unnaturalness) hypotheses of religion must be merged. Finally, a preliminary analysis of the “New Atheism” is offered in terms of semiotic and cognitive dynamics. 相似文献

The term ‘Climategate’ refers to the episode in November 2009 when emails between climate scientists were stolen and published online. The content of this private correspondence prompted criticism from diverse commentators who cast doubts on the methods, claims, and members of the climate science community. In response, individual scientists and scientific institutions published statements responding to the allegations of scientific fraud. Gieryn's concept of ‘boundary-work’ can be used to analyse the rhetoric of scientists in situations where their legitimacy is disputed. More specifically, boundary-work can be used to analyse the responses of scientists in terms of: how they represent the attributes of science, what types of boundary-work they undertake (e.g. expulsion, expansion, and protection), and the professional interests that come into play. A boundary-work analysis of the commentaries published in the aftermath of Climategate reveals that scientists characterised climate science as consensual, asocial, and open. Scientists depicted climate science as consensual with the purpose of expelling dissenters and protecting areas of climate science from criticism. Scientists also described knowledge about climate as being ideally produced apart from society so that they could preserve their autonomy and exclude individuals who are accused of being ‘politically biased’. Scientists characterised climate science as necessarily open as the means to justify both existing and additional public funding for science and to avoid external corrective interventions against scientific opacity. Scientists and their critics alike interpreted the stolen emails as embarrassing deviations from the alleged social demands of a consensual, objective, and accessible science. 相似文献

Wilhelm Dilthey is, famously, an epistemological pioneer for a second, ‘human’ kind of science that ‘understands’ life as we live it, instead of ‘explaining’ things as we observe them. Even today, he is usually cited for his role in the Erklären–Verstehen debate. My article, however, follows Heidegger's suggestion that we make the existence of the debate itself the problem. Whether there are different sorts of entity, different reasons for studying them and different means for doing so – such issues raise questions about science itself, not just about how to do it better. Moreover, what sort of philosopher is competent to address such questions? Heidegger argues that Dilthey's later writings intimate that it must be one who thinks from the ‘standpoint of (historical) life itself.’ This issue, says Heidegger, is ‘alive’ in Dilthey but is continually short-circuited by his very traditional plan for a ‘Critique of Historical Reason.’ Dilthey's unsuccessful struggles to produce this Critique are his gift to us, however. They encourage us to explicitly reconsider, as Heidegger does not only in Being and Time but throughout his life, what Dilthey cannot: If philosophy, like all human practices, is historical to the core, what is it to ‘be’ philosophical, about science or anything else? 相似文献

Nowadays, the criticism of the so-called ‘deficit model’ and the need for ‘upstream engagement’ in science and technology are becoming part of the master narratives of public policies in many countries, especially concerning nanotechnology. This may be considered as a major success for STS scholars, whose research results have largely contributed to this change, especially those concerning the GMO controversies. Some STS scholars thus move from a position of distant and critical observers to the role of experts in social engineering or advisers of policy-makers. However, in their enthusiasm concerning the expected benefits of upstream engagement, institutions, TA practitioners and social scientists seem to ignore some important limitations as well as the implicit framing assumptions of the concept. Based on an experience made by a group of social scientists in the Grenoble area—one of the major ‘nanodistricts’ in Europe—our paper shows that the ‘upstream engagement’ concept is still embedded in a linear model of innovation and is not very useful to anyone pursuing the co-production of innovations. It is especially true when socio-technical networks are already aligned by powerful actors and a worldwide agenda as in the case of nanotechnology. In order to give an opportunity for public engagement to have a larger impact on decision-making, we propose an alternative approach, which combines Actor–Network Theory (ANT), as an analytical tool, with the reflexive and ongoing implementation of public participation. Public engagement is probably one of the critical loci where STS scholars must reflect on the articulation between the knowledge they produce and public policies in action. 相似文献

This article examines a narrative dilemma that popular texts on evolution face. On the one hand, popular science tends to privilege linear and culturally familiar narrative structures, as previous studies of popularization have often emphasized. On the other hand, however, the Darwinian idea of natural selection resists linear narration, as narrative theorist H. Porter Abbott has argued. This resistance arises from the fact that evolution by natural selection lacks proper narrative entities and narrative events and that it relies on two parallel narrative levels, the levels of species and organism. This paper explores how two popular science books on evolution negotiate this narrative dilemma by introducing a third narrative level. Both texts appropriate characteristics from the narrative levels of species and organism and project them on molecular and minute scales by portraying evolution as a micro-narrative that takes place in chromosomes, genes, cells and microscopic details of human organs. While this textual strategy produces a coherent and compelling narrative that for the most part succeeds in masking the structural gap between the narrative levels of species and organism, it also risks naturalizing cultural imagery. In particular, this micro-narrative tends to represent popular gender ideologies as biological truths embedded in molecular processes within our bodies. 相似文献
