The paper considers contemporary models of presumption in terms of their ability to contribute to a working theory of presumption for argumentation. Beginning with the Whatelian model, we consider its contemporary developments and alternatives, as proposed by Sidgwick, Kauffeld, Cronkhite, Rescher, Walton, Freeman, Ullmann-Margalit, and Hansen. Based on these accounts, we present a picture of presumptions characterized by their nature, function, foundation and force. On our account, presumption is a modal status that is attached to a claim and has (...) the effect of shifting, in a dialogue, a burden of proof set at a local level. Presumptions can be analysed and evaluated inferentially as components of rule-based structures. Presumptions are defeasible, and the force of a presumption is a function of its normative foundation. This picture seeks to provide a framework to guide the development of specific theories of presumption. (shrink)

While courts depend on expert opinions in reaching sound judgments, the role of the expert witness in legal proceedings is associated with a litany of problems. Perhaps most prevalent is the question of under what circumstances should testimony be admitted as expert opinion. We review the changing policies adopted by American courts in an attempt to ensure the reliability and usefulness of the scientific and technical information admitted as evidence. We argue that these admissibility criteria are best seen in a (...) dialectical context as a set of critical questions of the kind commonly used in models of argumentation. (shrink)

Medicine regulation demands the application of sound medical, scientific, and technical knowledge and skills, and operates within a legal framework. Regulatory functions involve interactions with various stakeholders (e.g., manufacturers, traders, consumers, health professionals, researchers, and governments) whose economic, social, and political motives may differ, making implementation of regulation both politically and technically challenging. This book discusses regulatory landscape globally and the current global regulatory scenario of medicinal products and food products comprehensively.

The attitudes of patients' to consent have changed over the years, but there has been little systematic study of the attitudes of anaesthetists and surgeons in this process. We aimed to describe observations made on the attitudes of medical professionals working in the UK to issues surrounding informed consent.

There is general acknowledgement that both the anterior cingulate and orbitofrontal cortex are implicated in reinforcement-guided decision making, and emotion and social behaviour. Despite the interest that these areas generate in both the cognitive neuroscience laboratory and the psychiatric clinic, ideas about the distinctive contributions made by each have only recently begun to emerge. This reflects an increasing understanding of the component processes that underlie reinforcement- guided decision making, such as the representation of reinforcement expectations, the exploration, updating and representation (...) of action values, and the appreciation that choices are guided not just by the prospect of reward but also by the costs that action entails. Evidence is emerging to suggest that the anterior cingulate and orbitofrontal cortex make distinct contributions to each of these aspects of decision making. (shrink)

This article aims to contribute to the application of ethical frameworks to public health policy. In particular, the article considers the use of the Nuffield Council on Bioethics stewardship model, as an applied framework for the evaluation of evidence within public health policymaking. The ‘Stewardship framework’ was applied to a policy proposal to restrict marketing of food and beverages to children. Reflections on applying the stewardship model as a framework are provided. The article concludes that the questions used to apply (...) the stewardship model usefully introduced ethical considerations into the evidence review. However, the real value will likely come from the type of policy process within which the framework is used, identifying competing value positions and capturing local value requirements. (shrink)

The operation of the human intellect is twofold, however; first, simple perception, 'simple apprehension,' the 'simple gaze of indivisibles' and second, composition and division or judgment. In considering the principles of human knowledge it is therefore necessary to distinguish simple principles from complex principles or axioms. It is evident, however, that being is absolutely first of all complex as well as incomplex principles. "That which first falls under apprehension is being, the understanding of which is included in all things whatsoever (...) man apprehends. Therefore, the first indemonstrable principle is the same cannot be affirmed and denied at the same time, which is based on the constitutive intelligibility of being and non-being: and on this principle all others are based.".

According to St. Thomas Aquinas, "that which is said to exist through any nature is called a suppositum or subject of that nature. For example, that which has the nature of horse is said to be a subject or suppositum of equine nature." Subjects or supposita, moreover, occupy all the room there is in the Thomistic universe, since existence belongs properly only to individual subjects. These may be simple, as in the case of separate intelligences or composite as in the (...) case of inanimate and animate substances: "existence belongs properly to subsisting things, whether they be simple, as in the case of separate substances, or composite, as in the case of material substances. For the act of existing belongs properly to that which has existence: that is, to that which subsists in its own existence.". (shrink)

The Nature and Status of Critical Questions in Argumentation Schemes.

Knowledge plays an important role in argumentation. Yet, recent work shows that standard conceptions of knowledge in epistemology may not be entirely suitable for argumentation. This paper explores the role of knowledge in argumentation, and proposes a notion of knowledge that promises to be more suitable for argumentation by taking account of: its dynamic nature, the defeasibility of our commitments, and the non-monotonicity of many of the inferences we use in everyday reasoning and argumentation.

Each annual Ontology Summit initiative makes a statement appropriate to each Summit’s theme as part of our general advocacy designed to bring ontology science and engineering into the mainstream. The theme this year is "Towards an Open Ontology Repository". This communiqué represents the joint position of those who were engaged in the year's summit discourse on an Open Ontology Repository (OOR) and of those who endorse below. In this discussion, we have agreed that an "ontology repository is a facility where (...) ontologies and related information artifacts can be stored, retrieved and managed." -/- We believe in the promise of semantic technologies based on logic, databases and the Semantic Web, a Web of exposed data and of interpretations of that data (i.e., of semantics), using common standards. Such technologies enable distinguishable, computable, reusable, and sharable meaning of Web and other artifacts, including data, documents, and services. We also believe that making that vision a reality requires additional supporting resources and these resources should be open, extensible, and provide common services over the ontologies. (shrink)
