The moral importance of the ‘intention–foresight’ distinction has long been a matter of philosophical controversy, particularly in the context of end-of-life care. Previous empirical research in Australia has suggested that general physicians and surgeons may use analgesic or sedative infusions with ambiguous intentions, their actions sometimes approximating ‘slow euthanasia’. In this paper, we report findings from a qualitative study of 18 Australian palliative care medical specialists, using in-depth interviews to address the use of sedation at the end of life. The (...) majority of subjects were agnostic or atheistic. In contrast to their colleagues in acute medical practice, these Australian palliative care specialists were almost unanimously committed to distinguishing their actions from euthanasia. This commitment appeared to arise principally from the need to maintain a clear professional role, and not obviously from an ideological opposition to euthanasia. While some respondents acknowledged that there are difficult cases that require considered reflection upon one's intention, and where there may be some ‘mental gymnastics,’ the nearly unanimous view was that it is important, even in these difficult cases, to cultivate an intention that focuses exclusively on the relief of symptoms. We present four narratives of ‘terminal’ sedation – cases where sedation was administered in significant doses just before death, and may well have hastened death. Considerable ambiguities of intention were evident in some instances, but the discussion around these clearly exceptional cases illustrates the importance of intention to palliative care specialists in maintaining their professional roles.

This paper aims to identify the key characteristics of model organisms that make them a specific type of model within the contemporary life sciences: in particular, we argue that the term “model organism” does not apply to all organisms used for the purposes of experimental research. We explore the differences between experimental and model organisms in terms of their material and epistemic features, and argue that it is essential to distinguish between their representational scope and representational target. We also examine (...) the characteristics of the communities who use these two types of models, including their research goals, disciplinary affiliations, and preferred practices to show how these have contributed to the conceptualization of a model organism. We conclude that model organisms are a specific subgroup of organisms that have been standardized to fit an integrative and comparative mode of research, and that it must be clearly distinguished from the broader class of experimental organisms. In addition, we argue that model organisms are the key components of a unique and distinctively biological way of doing research using models. (shrink)
There has been much debate regarding the 'double-effect' of sedatives and analgesics administered at the end-of-life, and the possibility that health professionals using these drugs are performing 'slow euthanasia.' On the one hand analgesics and sedatives can do much to relieve suffering in the terminally ill. On the other hand, they can hasten death. According to a standard view, the administration of analgesics and sedatives amounts to euthanasia when the drugs are given with an intention to hasten death. In this (...) paper we report a small qualitative study based on interviews with 8 Australian general physicians regarding their understanding of intention in the context of questions about voluntary euthanasia, assisted suicide and particularly the use of analgesic and sedative infusions (including the possibility of voluntary or non-voluntary 'slow euthanasia'). We found a striking ambiguity and uncertainty regarding intentions amongst doctors interviewed. Some were explicit in describing a 'grey' area between palliation and euthanasia, or a continuum between the two. Not one of the respondents was consistent in distinguishing between a foreseen death and an intended death. A major theme was that 'slow euthanasia' may be more psychologically acceptable to doctors than active voluntary euthanasia by bolus injection, partly because the former would usually only result in a small loss of 'time' for patients already very close to death, but also because of the desirable ambiguities surrounding causation and intention when an infusion of analgesics and sedatives is used. The empirical and philosophical implications of these findings are discussed. (shrink)
Calls for the “translation” of research from bench to bedside are increasingly demanding. What is translation, and why does it matter? We sketch the recent history of outcome-oriented translational research in the United States, with a particular focus on the Roadmap Initiative of the National Institutes of Health (Bethesda, MD). Our main example of contemporary translational research is stem cell research, which has superseded genomics as the translational object of choice. We explore the nature of and obstacles to translational research (...) and assess the ethical and biomedical challenges of embracing a translational ethos. (shrink)
This paper considers the legislative debates in Australia that led to the passage of the Research Involving Human Embryos Act (Cth 2002) and the Prohibition of Human Cloning Act (Cth 2002). In the first part of the paper, we discuss the debate surrounding the legislation with particular emphasis on the ways in which demands for public consultation, public debate and the education of Australians about the potential ethical and scientific impact of human embryonic stem cells (hESC) research were deployed, and (...) the explicit and implicit framing of the scope of public consultation. We then ask whether, given the calls for public consultations, debate and understanding, current work in democratic theory could be helpful in analysing the process of policy-making in these areas. In particular, we canvass the literature relating to aggregative and deliberative models of democracy for processes that support the legitimacy of policy. We identify features of the debate that reflect the appeal of deliberative approaches as well as some of the possible hurdles or limitations to developing deliberative democratic approaches to policy in ethically contentious areas.

Human embryonic stem cell research has generated considerable discussion and debate in bioethics. Bioethical discourse tends to focus on the moral status of the embryo as the central issue, however, and it is unclear how much this reflects broader community values and beliefs related to stem cell research. This paper presents the results of a study which aims to identify and classify the issues and arguments that have arisen in public discourse associated with one prominent policy episode in (...) the United States: the 2004 Californian Stem Cell Research and Cures Initiative (also known as Proposition 71). The findings show that public discourse about Proposition 71 is characterised by a broader range of issues than those usually addressed in scholarly publications and public policy documents. While attention to the moral status of the embryo is an important issue in stem cell research, making it the main focus of public discourse has a polarising effect. This also limits opportunities to identify shared values, understand how political alliances are forged, and develop social consensus. Implications for future research and policy are discussed.

Is inheritable genetic modification the new dividing line in gene therapy? The editors of this searching investigation, representing clinical medicine, public health and biomedical ethics, have established a distinguished team of scientists and scholars to address the issues from the perspectives of biological and social science, law and ethics, including an intriguing Foreword from Peter Singer. Their purpose is to consider how society might deal with the ethical concerns raised by inheritable genetic modification, and to re-examine prevailing views about whether (...) these procedures will ever be ethically and socially justifiable. The book also provides background to define the field, and discusses the biological and technological potential for inheritable genetic modification, its limitations, and its connection with gene therapy, cloning, and other reproductive interventions. For scientists, bioethicists, clinicians, counsellors and public commentators, this is an essential contribution to one of the critical debates in current genetics. (shrink)
Through an examination of the actual research strategies and assumptions underlying the Human Genome Project (HGP), it is argued that the epistemic basis of the initial model organism programs is not best understood as reasoning via causal analog models (CAMs). In order to answer a series of questions about what is being modeled and what claims about the models are warranted, a descriptive epistemological method is employed that uses historical techniques to develop detailed accounts which, in turn, help to reveal (...) forms of reasoning that are explicit, or more often implicit, in the practice of a particular field of scientific study. It is suggested that a more valid characterization of the reasoning structure at work here is a form of case-based reasoning. This conceptualization of the role of model organisms can guide our understanding and assessment of these research programs, their knowledge claims and progress, and their limitations, as well as how we educate the public about this type of biomedical research.

The biological sciences have become increasingly reliant on so-called 'model organisms'. I argue that in this domain, the concept of a descriptive model is essential for understanding scientific practice. Using a case study, I show how such a model was formulated in a preexplanatory context for subsequent use as a prototype from which explanations ultimately may be generated both within the immediate domain of the original model and in additional, related domains. To develop this concept of a descriptive model, I (...) focus on use of the nematode worm Caenorhabditis elegans and the wiring diagrams that were developed as models of its neural structure. In addition, implications of the concept of a descriptive model, particularly its relevance for the data-phenomena distinction as well as its relation to long-standing debates on realism, are briefly examined.

The so-called "biometric-Mendelian controversy" has received much attention from science studies scholars. This paper focuses on one scientist involved in this debate, Arthur Dukinfield Darbishire, who performed a series of hybridization experiments with mice beginning in 1901. Previous historical work on Darbishire's experiments and his later attempt to reconcile Mendelian and biometric views describe Darbishire as eventually being "converted" to Mendelism. I provide a new analysis of this episode in the context of Darbishire's experimental results, his underlying epistemology, and his (...) influence on the broader debate surrounding the rediscovery and acceptance of Mendelism. I investigate various historiographical issues raised by this episode in order to reflect on the idea of "conversion" to a scientific theory. Darbishire was an influential figure who resisted strong forces compelling him to convert prematurely due to his requirements that the new theory account for particularly important anomalous facts and answer the most pressing questions in the field.
