We present a new method for characterizing the interpretive possibilities generated by elliptical constructions in natural language. Unlike previous analyses, which postulate ambiguity of interpretation or derivation in the full clause source of the ellipsis, our analysis requires no such hidden ambiguity. Further, the analysis follows relatively directly from an abstract statement of the ellipsis interpretation problem. It predicts correctly a wide range of interactions between ellipsis and other semantic phenomena such as quantifier scope and bound anaphora. Finally, although the (...) analysis itself is stated nonprocedurally, it admits of a direct computational method for generating interpretations. (shrink)

Anti-behaviorist arguments against the validity of the Turing Test as a sufficient condition for attributing intelligence are based on a memorizing machine, which has recorded within it responses to every possible Turing Test interaction of up to a fixed length. The mere possibility of such a machine is claimed to be enough to invalidate the Turing Test. I consider the nomological possibility of memorizing machines, and how long a Turing Test they can pass. I replicate my previous analysis of this (...) critical Turing Test length based on the age of the universe, show how considerations of communication time shorten that estimate and allow eliminating the sole remaining contingent assumption, and argue that the bound is so short that it is incompatible with the very notion of the Turing Test. I conclude that the memorizing machine objection to the Turing Test as a sufficient condition for attributing intelligence is invalid. (shrink)

In 1950, Alan Turing proposed his eponymous test based on indistinguishability of verbal behavior as a replacement for the question "Can machines think?" Since then, two mutually contradictory but well-founded attitudes towards the Turing Test have arisen in the philosophical literature. On the one hand is the attitude that has become philosophical conventional wisdom, viz., that the Turing Test is hopelessly flawed as a sufficient condition for intelligence, while on the other hand is the overwhelming sense that were a machine (...) to pass a real live full-fledged Turing Test, it would be a sign of nothing but our orneriness to deny it the attribution of intelligence. The arguments against the sufficiency of the Turing Test for determining intelligence rely on showing that some extra conditions are logically necessary for intelligence beyond the behavioral properties exhibited by an agent under a Turing Test. Therefore, it cannot follow logically from passing a Turing Test that the agent is intelligent. I argue that these extra conditions can be revealed by the Turing Test, so long as we allow a very slight weakening of the criterion from one of logical proof to one of statistical proof under weak realizability assumptions. The argument depends on the notion of interactive proof developed in theoretical computer science, along with some simple physical facts that constrain the information capacity of agents. Crucially, the weakening is so slight as to make no conceivable difference from a practical standpoint. Thus, the Gordian knot between the two opposing views of the sufficiency of the Turing Test can be cut. (shrink)

Systematic semantic ambiguities result from the interaction of the two operations that are involved in resolving ellipsis in the presence of scoping elements such as quantifiers and intensional operators: scope determination for the scoping elements and resolution of the elided relation. A variety of problematic examples previously noted - by Sag, Hirschbüihler, Gawron and Peters, Harper, and others - all have to do with such interactions. In previous work, we showed how ellipsis resolution can be stated and solved in equational (...) terms. Furthermore, this equational analysis of ellipsis provides a uniform framework in which interactions between ellipsis resolution and scope determination can be captured. As a consequence, an account of the problematic examples follows directly from the equational method. The goal of this paper is merely to point out this pleasant aspect of the equational analysis, through its application to these cases. No new analytical methods or associated formalism are presented, with the exception of a straightforward extension of the equational method to intensional logic. (shrink)

Working within the tradition of continental philosophy, this article argues in favour of a phenomenological understanding of language as a crucial component of bioethical inquiry. The authors challenge the ‘commonsense’ view of language, in which thinking appears as prior to speaking, and speech the straightforward vehicle of pre-existing thoughts. Drawing on Maurice Merleau-Ponty's (1908–1961) phenomenology of language, the authors claim that thinking takes place in and through the spoken word, in and through embodied language. This view resituates bioethics as a (...) matter of bodies that speak. It also refigures the meaning of ethical self-reflexion, and in so doing offers an alternative view on reflexivity and critique. Referring to the Kantian critical tradition and its reception by Hannah Arendt and Michel Foucault, we advance a position we call ‘critical ethical reflexivity’. We contend that Merleau-Ponty's phenomenology of language offers valuable insight into ethical reflexivity and subject formation. Moreover, his understanding of language may foster new qualitative empirical research in bioethics, lead to more nuanced methods for interpreting personal narratives, and promote critical self-reflexion as necessary for bioethical inquiry.

This is the first book to take a comprehensive look at white collar criminal offenses from the perspective of moral and legal theory. Focussing on the way in which key white collar crimes such as fraud, perjury, false statements, obstruction of justice, bribery, extortion, blackmail, insider trading, tax evasion, and regulatory and intellectual property offenses are shaped and informed by a range of familiar, but nevertheless powerful, moral norms.

The concept of social structure is ill defined in the literature despite the perennial problem and ongoing discussion about the relationship between agency and structure. In this paper I will provide an outline of what the term social structure means, but my main focus will be on emphasizing the value of the concept for nursing research and demonstrate how its erasure in some research negatively effects on our understanding of the nurses' role in clinical practice. For example, qualitative research in (...) nursing has largely focused on agency through such theories as phenomenology, hermeneutics, and symbolic interactionism. The result is that social structure may be erased or seen as epiphenomena of agency. My purpose is to provide a theoretical discussion of social structure and how such a discussion can help us to understand how nurses live and experience clinical practice. While not denying the importance of agency, I will argue that the thinned out approach to social structure places limits on our understanding of the constraints nurses experience in their working lives. The result is that nurses' attitudes and clinical failings are individualized, resulting in ever more calls for improved education, when a more thorough examination of structural issues may elucidate more fundamental problems.

We argue that the physics of complex materials and self-organizing processes should be made central to the biology of form. Rather than being encoded in genes, form emerges when cells and certain of their molecules mobilize physical forces, effects, and processes in a multicellular context. What is inherited from one generation to the next are not genetic programs for constructing organisms, but generative mechanisms of morphogenesis and pattern formation and the initial and boundary conditions for reproducing the specific traits of (...) a taxon. There is no inherent antagonism between this “physicalist” perspective and genetics, since physics acts on matter, and gene products are essential material components of living systems whose variability affects the systems’ parameters. We make this notion concrete by summarizing the concept of “dynamical patterning modules” (DPMs; Newman and Bhat, Phys Biol 5:1–14, 2008; Int J Dev Biol 53:693–705, 2009), an explicit physico-genetic framework for the origin and evolution of multicellular form in animals, as well as (when differences in interaction toolkit genes and applicable physical processes are taken into account) in multicellular plants (Hernández-Hernández et al., Int J Dev Biol 56:661–674, 2012). DPMs provide the missing link between development and evolution by revealing how genes acting in concert with physics can generate and transform morphology in a heritable fashion. (shrink)

In his article ‘The case against ethics review in the social sciences’, Schrag asserts that the social sciences should not be subject to ethical review. He recounts a number of examples where ethical review has seemingly failed. He further suggests some alternative models for dealing with ethical review in the social sciences. Finally, he concludes, and we concur, that there is a lack of empirical evidence as to the benefit of research ethics review.

In 2008, researchers reported that Timothy Brown , a man with HIV infection and leukemia, received a stem-cell transplant that removed HIV from his body as far as can be detected. In 2013, an infant born with HIV infection received anti-retroviral treatment shortly after birth, but was then lost to the health care system for the next six months. When tested for HIV upon return, the child had no detectable viral load despite cessation of treatment. These remarkable clinical developments have (...) helped reinvigorate the field of ‘HIV cure’ research. (shrink)

This paper will explore the relationship between Mezirow's concept of reflexivity and Bourdieu's theory of habitus in order to develop a more robust framework within which critical reflection can take place. Nurse educators have sought to close the theory practice gap through the use of critical reflection. However, we are not convinced that this has produced the depth and quality of reflection required. Furthermore, the contexts in which critical reflection takes place is often sidelined or erased so that the whole (...) impetus in the literature is to educate nurses in reflection rather than empower nurses to understand the complex circumstances and barriers that obstruct critical reflection. This paper argues that the reason for this position is that nurse education does not always acknowledge the role that personal and cultural values systems have on reflective practices. The literature search was undertaken using CINHAL and MEDLINE. Keywords included: values systems, habitus, and critical reflection. Inclusion criteria were determined by the theoretical approach and included seminal texts, from as far back as 1956, to identify key themes. Although critical reflection is a potentially powerful way of enhancing care it has often failed to do so. It is suggested that this is because nurse educators have frequently used models of reflection without considering the impact that student's personal values systems has on their perceptions of care and subsequently care delivery. The purpose of this paper is to promote deeper levels of reflection and is part of a programme of research aimed at developing a more robust approach to reflection in educational practice. (shrink)

Newborn screening is the programme through which newborn babies are screened for a variety of conditions shortly after birth. Programmes such as this are individually oriented but resemble traditional public health programmes because they are targeted at large groups of the population and they are offered as preventive interventions to a population considered healthy. As such, an ethical tension exists between the goals of promoting the high uptake of supposedly ‘effective’ population-oriented programmes and the goal of promoting genuinely informed decision-making. (...) There is, however, a lack of understanding with regard to how parents experience the tension between promoting uptake and facilitating informed choice. This paper addresses this issue, and data are presented to show how aspects of the timing, presentation of information and procedural routinisation of newborn screening serves to impact on the decisions made by parents.

Proposed changes to the Common Rule are proffered to save almost 7,000 reviews annually and consequently vast amounts of investigator and IRB-member time. However, the proposed changes have been subject to criticism. While some have lauded the changes as being imperfect, but nevertheless as improvements, others have contended that ‘neither the scientific community nor the public can be confident that improved practices will emerge from the regulatory changes mandated by the NPRM.’ In the present article, I discuss an important aspect (...) that has been overlooked: the question of whether benefits will emerge is demonstrably empirical, yet data upon which to draw conclusions are conspicuous by their absence. This is thrown into sharp relief when we consider the current environment in which health research is increasingly focused on providing evidence of need or benefit, where there is greater emphasis on evidence-based practice, and when we have the nascent field of implementation science.

During vertebrate limb development, various genes of the Hox family, the products of which influence skeletal element identity, are expressed in specific spatiotemporal patterns in the limb bud mesenchyme. At the same time, the cells also exhibit ‘self‐organizing’ behavior – interacting with each other via extracellular matrix and cell‐cell adhesive molecules to form the arrays of mesenchymal condensations that lead to the cartilaginous skeletal primordia. A recent study by Yokouchi et al.(1) establishes a connection between these phenomena. They misexpressed the (...) product of the Hoxa‐13 gene in chick limb buds and demonstrated both skeletal pattern perturbations and changes in cell‐cell adhesivity in mesenchyme aberrantly expressing this protein.

The UK has a long established programme of newborn bloodspot screening. This operates under a model of informed choice. Understanding is central to the `informed’ element of an informed choice yet it is rarely assessed. To date most research within the context of newborn bloodspot screening has focussed on parental recall of information. In this paper I argue that simplistic assessments of knowledge through recall fail to reflect more complex notions of understanding. In support of this contention I draw on (...) qualitative interviews with parents of children who have undergone newborn bloodspot screening. (shrink)

Randomized controlled trial trial designs exist on an explanatory-pragmatic spectrum, depending on the degree to which a study aims to address a question of efficacy or effectiveness. As conceptualized by Schwartz and Lellouch in 1967, an explanatory approach to trial design emphasizes hypothesis testing about the mechanisms of action of treatments under ideal conditions, whereas a pragmatic approach emphasizes testing effectiveness of two or more available treatments in real-world conditions. Interest in, and the number of, pragmatic trials has grown substantially (...) in recent years, with increased recognition by funders and stakeholders worldwide of the need for credible evidence to inform clinical decision-making. This increase has been accompanied by the onset of learning healthcare systems, as well as an increasing focus on patient-oriented research. However, pragmatic trials have ethical challenges that have not yet been identified or adequately characterized. The present study aims to explore the views of key stakeholders with respect to ethical issues raised by the design and conduct of pragmatic trials. It is embedded within a large, four-year project that seeks to develop guidance for the ethical design and conduct of pragmatic trials. As a first step, this study will address important gaps in the current empirical literature with respect to identifying a comprehensive range of ethical issues arising from the design and conduct of pragmatic trials. By opening up a broad range of topics for consideration within our parallel ethical analysis, we will extend the current debate, which has largely emphasized issues of consent, to the range of ethical considerations that may flow from specific design choices. Semi-structured interviews with key stakeholders, across multiple jurisdictions, identified based on their known experience and/or expertise with pragmatic trials. We expect that the study outputs will be of interest to a wide range of knowledge users including trialists, ethicists, research ethics committees, journal editors, regulators, healthcare policymakers, research funders and patient groups. All publications will adhere to the Tri-Agency Open Access Policy on Publications. (shrink)

When two populations of cells within a tissue mass differ from one another in magnitude or type of intercellular adhesions, a boundary can form within the tissue, across which cells will fail to mix. This phenomenon may occur regardless of the identity of the molecules that mediate cell adhesion. If, in addition, a choice between the two adhesive states is regulated by a molecule the concentration of which is periodic in space, or in time, then alternating bands of non‐mixing tissue, (...) or segments, can form. But temporal or spatial periodicities in concentration will tend to arise for any molecule that is positively autoregu‐latory. It is therefore proposed that segmentation is a ‘generic’ property of metazoan organisms, and that metamerism would be expected to have emerged numerous times during evolution. A simple model of segmentation, based solely on differential adhesion and periodic regulation of adhesion, can account for segment properties as disparate as those seen in long and short germ band insects, and for diverse experimental results on boundary regeneration in the chick hind brain and the insect cuticle. It is suggested that the complex, multicom‐ponent segment‐forming systems found in contemporary organisms (e.g., Drosophila) are the products of evolutionary recruitment of molecular cues such as homeobox gene products, that increase the reliability and stability of metameric patterns originally templated by generic self‐organizing properties of tissues.

This essay reads J.M. Coetzee’s novel, Diary of a Bad Year, as an occasion to problematize contemporary bioethical paradigms. Coetzee’s rhetorical strategies are analyzed to better understand the “scene of address” within which ethical claims can be voiced. Drawing on Foucault’s Socratic understanding of ethics as the self’s relation to itself, self-relation is explored through the rhetorical figure of catachresis. The essay ultimately argues that the ethical voice emerges when the terms—terms by which I relate to myself, to others, to (...) my own body, and to the bodies of others—are themselves subject to catachrestic refiguration.

Since the end of the Cold War, the scope and study of diplomacy has expanded. In the modern diplomatic environment, novel terms such as pipeline diplomacy, coercive diplomacy, diplomacy by sanction and citizen diplomacy are common, alongside the more traditional view of diplomacy as state-to-state activity, monopolized by professional, official diplomats. With such a broad range of views, the scholar can become confused as to what actually constitutes modern diplomacy? In this article, it is argued that the disparity of views (...) in the diplomacy studies field must be classified and consolidated before the enhanced role of diplomacy in the twenty-first century can be better understood. In this article, three different classifications or schools of diplomatic thought are introduced and constructed: the Traditional School, the Nascent School, and the Innovative School. (shrink)
