Our primary focus is on analysis of the concept of voluntariness, with a secondary focus on the implications of our analysis for the concept and the requirements of voluntary informed consent. We propose that two necessary and jointly sufficient conditions must be satisfied for an action to be voluntary: intentionality, and substantial freedom from controlling influences. We reject authenticity as a necessary condition of voluntary action, and we note that constraining situations may or may not undermine voluntariness, depending on the (...) circumstances and the psychological capacities of agents. We compare and evaluate several accounts of voluntariness and argue that our view, unlike other treatments in bioethics, is not a value-laden theory. We also discuss the empirical assessment of individuals? perceptions of the degrees of noncontrol and self-control. We propose use of a particular Decision Making Control Instrument. Empirical research using this instrument can provide data that will help establish appropriate policies and procedures for obtaining voluntary consent to research. (shrink)

How Classification Works attempts to bridge the gap between philosophy and the social sciences using as a focus some of the work of Nelson Goodman. Throughout his long career Goodman has addressed the question: are some ways of conceptualizing more natural than others? This book looks at the rightness of categories, assessing Goodman's role in modern philosophy and explaining some of his ideas on the relation between aesthetics and cognitive theory. Two papers by Nelson Goodman are included in (...) the collection and there are analyses of his work by seven leading academics in anthropology, philosophy, sociology and musicology. (shrink)

Social networks play a significant role in learning and thus in farmers’ adoption of new agricultural technologies. This study examined the effects of social network factors on information acquisition and adoption of new seed varieties among groundnut farmers in Uganda and Kenya. The data were generated through face-to-face interviews from a random sample of 461 farmers, 232 in Uganda and 229 in Kenya. To assess these effects two alternative econometric models were used: a seemingly unrelated bivariate probit model and a (...) recursive bivariate probit model. The statistical evaluation of the SUBP shows that information acquisition and adoption decisions are interrelated while tests for the RBP do not support this latter model. Therefore, the analysis is based on the results obtained from the SUBP. These results reveal that social network factors, particularly weak ties with external support, partially influence information acquisition, but do not influence adoption. In Uganda, external support, gender, farm size, and geographic location have an impact on information acquisition. In Kenya, external support and geographic location also have an impact on information acquisition. With regard to adoption, gender, household size, and geographic location play the most important roles for Ugandan farmers, while in Kenya information from external sources, education, and farm size affect adoption choice. The study provides insight on the importance of external weak ties in groundnut farming, and a need to understand regional differences along gender lines while developing agricultural strategies. This study further illustrates the importance of farmer participation in applied technology research and the impact of social interactions among farmers and external agents. (shrink)

In Tudor and Stuart Britain, women writers took active roles in negotiating cultural ideas and systems to gain power by participating in politics through writing, shaping the aesthetics of genre, and fashioning feminine gender, despite constraints on women. Through the lens of cultural studies, the authors explore the ways in which women of this era worked to actually create culture. Articles cover five areas: women, writing, and material culture; women as objects and agents in reproducing culture; women's role in producing (...) gender; popular culture and women's pamphlets; and women's bodies as inscriptions of culture.

Over the past two decades, the competency movement has been gathering momentum internationally within the ranks of professional nursing. It can be argued that this momentum is in response to government initiatives aimed at improving consistency in workforce training and accreditation, and fostering national and international portability of qualifications. At the same time, the competency movement has provided the opportunity for regulators, service providers and government to develop mechanisms to reconstitute competent nurses as accountable, self‐regulating subjects and to monitor this (...) transformation in particular ways. The ways in which competencies have been taken up to do this transforming work in Canada are unique and deserving of some detailed description and analysis.We argue that Canadian nursing regulatory authorities have chosen to view competence as the rehearsal of ethical attributes consonant with the professional role,as opposed to the enactment of skilled conduct. As a result, reflective practices rather than skill and knowledge have become the cornerstone of nursing competency formulation and review. We argue that this distinctly Canadian approach to competency serves three ends. First, it privileges the ‘attribute’ element of the nursing competency model and side steps the ever‐problematic ‘nursing knowledge’ issue; second, self‐surveillance by nurses shifts the onus for professional development from industry to the individual; and third, it concedes responsibility for skill assessment by the regulatory authorities to industry control, leaving employers free to determine skill base and skill mix requirements for practice. Finally, we argue that the reflective component of the regulatory framework for Canadian nurses radically fails as a tool for auditing quality and assessing competency. Rather, it functions as a governmental practice that furthers the deregulatory and economic rationalist aims of the Canadian health reform agenda. (shrink)

The rural health context in the United States presents unique ethical challenges to its approximately 60 million residents, who represent about one quarter of the overall population and are distributed over three-quarters of the country’s land mass. The rural context is not only identified by the small population density and distance to an urban setting but also by a combination of social, religious, geographical, and cultural factors. Living in a rural setting fosters a sense of shared values and beliefs, a (...) strong work ethic, self-reliance, and a tendency for close-knit extended social structures where overlapping relationships are commonplace.

The purpose of this study was to assess the presence of ethics committees in rural critical access hospitals across the United States. Several studies have investigated the presence of ethics committees in rural health care facilities. The limitation of these studies is in the definition of ‘rural hospital’ and a regional or state focus. These limitations have created large variations in the study findings. In this nation-wide study we used the criteria of a critical access hospital (CAH), as defined by (...) the Medicare Rural Hospital Flexibility Program (Flex Program, 2007), to bring consistency and clarity to the assessment of the presence of ethics committees in rural hospitals. The Flex Monitoring Team conducted a national telephone survey of 381 CAH administrators throughout the United States. The survey covered a wide variety of questions concerning hospitals’ community benefit, impact activities, and whether the hospital had a formally established an ethics committee. About 230 (60%) of the respondents indicated they had a formally established ethics committee or ethics consultation program at their CAH. The prevalence of ethics committees declined as the CAH location became increasingly rural along a rural–urban continuum. Unlike CAHs, all rural Department of Veterans Affairs Medical Centers have ethics committees. The results of this study provide an understanding of the limited presence of ethics committee in rural America and the need to consider new approaches for providing ethics assistance. A virtual ethics committee network may be the most efficient and effective way of providing rural hospitals access to a knowledgeable ethics committee or consultant. (shrink)

The ethical standard for informed consent is fostered within a shared decision-making process. SDM has become a recognized and needed approach in health care decision-making. Based on an ethical foundation, the approach fosters the active engagement of patients, where the clinician presents evidence-based treatment information and options and openly elicits the patient’s values and preferences. The SDM process is affected by the context in which the information exchange occurs. Rural settings are one context that impacts the delivery of health care (...) and SDM. Rural health care is significantly influenced by economic, geographical and social characteristics. Several specific distinctive features influence rural health care decision-making—poverty, access to health care, isolation, over-lapping relationships, and a shared culture. The rural context creates challenges as well as fosters opportunities for the application of SDM as a natural dynamic within the rural provider–patient relationship. To fulfill the ethical requirements of informed consent through SDM, it is necessary to understand its inherent challenges and opportunities. Therefore, rural clinicians and ethicists need to be cognizant of the impact of the rural setting on SDM and use the insights as an opportunity to achieve SDM. (shrink)

How should clinical ethicists be trained? Scholars have stated that clinical ethics fellowships create well-trained, competent ethicists. While this appears intuitive, few features of fellowship programs have been publicly discussed, let alone debated. In this paper, we examine how fellowships can foster effective mentoring relationships. These relationships provide the foundation for the fellow’s transition from novice to competent professional. In this essay, we begin by discussing our pedagogical commitments. Next, we describe the structures our program has created to assist our (...) fellows in becoming competent ethicists. We then outline the kinds of knowledge, skills, and professional attributes mentors should possess. Following this, we focus on the knowledge, skills, and professional attributes that fellows develop as they co-create effective mentoring relationships. We will not prescribe a single approach to fellowship training; instead, our perspective will, we hope, become a catalyst for further conversation on training and mentoring clinical ethics fellows.

Philosophy's traditional "man of reason"—independent, neutral, unemotional—is an illusion. That's because the "man of reason" ignores one very important thing—the woman. Representing Reason: Feminist Theory and Formal Logic collects new and old essays that shed light on the underexplored intersection of logic and feminism.

Mary Ann Meeker’s article admirably reminds readers that family members are involved in—or “responsively manage”—the care of relatives with severe illness in ways that run considerably beyond the stereotypes at play in many bioethical discussions of advance directives. Her observations thus make thinking about the role of families in healthcare provision more adequate to the facts, and this is an important contribution. There’s reason to be worried, however, that one explicit aim of the article—to ease the standing anxieties that many (...) clinicians and ethicists have about the reliability of family members as proxy decision makers—will be frustrated by its very success. Those already inclined to suspicion may tend to think that the more intricate and pervasive the ways in which families influence the healthcare decision making of their sick, the more chances they have for altering the connection between patients’ interests and the actions of professional providers.To determine whether and when such alterations are something to be concerned about, we’ll need to supplement a better grasp of the pertinent facts with a deeper sense of how human agency works and why we value it. We may also need some reminders about the defensibility of diverse moral understandings. Although both professionals and family members may profess an ethic that sets patients’ interests above those of non-patients—as Meeker’s own results suggest—any strict allegiance to such a framework may be more notional than normative—as her findings also hint. The actual working norms (among professionals, as well as within families) will likely be more complex, but not necessarily any the less defensible for that. (shrink)

Our goal in producing this special issue is to encourage our colleagues to incorporate topics related to LGBT populations into bioethics curricula and scholarship. Bioethics has only rarely examined the ways in which law and medicine have defined, regulated, and often oppressed sexual minorities. This is an error on the part of bioethics. Medicine and law have served in the past as society's enforcement arm toward sexual minorities, in ways that robbed many people of their dignity. We feel that bioethics (...) has an obligation to discuss that history and to help us as a society take responsibility for it.We can address only a small number of topics in this special issue of the Hastings Center Report, and we selected topics we believe will stimulate discourse. Andrew Solomon offers an elegant overview of the challenges that bioethics faces in articulating a solid basis for LGBT rights. Timothy F. Murphy asks whether bioethics still faces issues related to lesbian, gay, and bisexual people, given the deletion of homosexuality as a disease and the progress toward same‐sex marriage. Jamie Lindemann Nelson's essay addresses the search for identity for transgender persons and the role of science in that search. Two articles, those by Brendan S. Abel and by Jack Drescher and Jack Pula, take up the complex issue of medical treatment for children who reject their assigned birth gender. Celia B. Fisher and Brian Mustanski address the special challenges of engaging LGBT youth in research, balancing the need for better information about this vulnerable group against the existing restrictions on research involving children. Tia Powell and Edward Stein consider the merits of legal bans on psychotherapies intended to change sexual orientation, particularly in the light of current research on orientation. Mary Beth Foglia and Karen I. Fredricksen‐Goldsen highlight health disparities and resilience among LGBT older adults and then discuss the role of nonconscious bias in perpetuating disparities. Stephan Davis and Nancy Berlinger assess the challenges of access to care and health policy for transgender persons. Edward J. Callahan et al. tackle the ways in which diverse aspects of medicine should change to better incorporate the needs of LGBT patients, including through use of the electronic medical record, education of health professionals, and recruitment efforts for LGBT health professionals. Virginia Ashby Sharpe and Uchenna S. Uchendu describe multifaceted efforts within Veterans Administration facilities to create change for LGBT veterans across the largest integrated health care network in the United States. Lance Wahlert and Autumn Fiester find a mixed record in the use of case studies in teaching about LGBT issues. (shrink)

The problem of reference is central to the fields of linguistics, cognitive science, and epistemology yet it remains largely unresolved. Naming and Reference explains the reference of lexical terms, with particular emphasis placed on proper names, demonstrative pronouns and personal pronouns. It examines such specific issues as: how to account for the reference of names that are empty or speculative, which abound in science and philosophy, and how to account for intentional reference as in "he took Mary to be Jane." (...) Naming and Reference begins with a survey of the history of the subject within a philosophical and critical setting, from Locke, Brentano, Peirce, Frege, Russell, Strawson, Tarski, Carnap and Quine up to Kripke and Fodor. The rest of the book is devoted to an algorithmic theory of reference derived from Peirce's idea that signification is a three-way relationship involving a term, an object and an interpretant. The theory rounds out the causal notion of reference, while at the same time preserving Frege's distinction between sense and reference, and making a place for indexical terms. Through the use of various computer models, R. J. Nelson explores the meaning and reference of words to objects and the relationship of these phenomena to perception, belief and truth. The models used are parallel, connectionist computational models rather than the sequential models of mid-century artificial intelligence. The aim, in opposition to nativist and mental representation theories, is to account for the genesis of semantically interpretable symbols, not to assume them. (shrink)

There is something about the debate over reproductive technologies of all kinds—from coerced use of Norplant to trait-selection technologies, to issues surrounding in vitro fertilization, to fetal tissue transplantation—that seems to invite dubious analogies. A Tennessee trial court termed Mary Sue and Junior Davis's frozen embryos “in vitro children” and applied a best-interests standard in awarding “custody” to Mary Sue Davis; the Warnock Committee drew an implicit analogy between human gametes and transplantable organs in its recommendation of a voluntary, nonprofit (...) system for collecting and distributing gametes in the United Kingdom; Owen Jones compares the right to trait-selection to the right to abortion; Robert Veatch once claimed that if a woman had signed an organ donation card and then died while pregnant, she had in effect given consent to the attempt to sustain the pregnancy after her death; John Robertson has argued that contract pregnancy poses no problems we have not already encountered with adoption; and Andrea Bonnicksen has compared the wonders of preembryonic genetic screening to the riches housed in the gold museum in Bogota, Colombia.

Mary Anne Warren's claim that there is room for only one person with full and equal rights inside a single human skin ([1], p. 63) calls attention to the vast range of moral conflict engendered by assigning full basic moral rights to fetuses. Thereby, it serves as a goad to thinking about conflicts between pregnant women and their fetuses in a way that emphasizes relationships rather than rights. I sketch out what a care orientation might suggest about resolving gestational conflicts. (...) I also argue that the care orientation, with its commitment to the significance of the partial and the particular, cannot be absorbed within standard, impartialist moral theory. (shrink)

Alexandra Shuford's book is primarily designed to address the following question: "What can Deweyan pragmatism contribute to a feminist empiricist epistemology?" (viii). Her answer is Dewey's conception of habit, and in her final chapter, she illustrates the utility of this conception by comparing what she labels the "medicalized" model of labor and birth to that employed by practitioners of midwifery. Before looking at Shuford's reading of this contrast more closely, however, it needs to be noted at the outset that she (...) also regards her constructive project to be one of "augmenting" or "extending" the efforts of Lynn Hankinson Nelson to formulate a feminist empiricism derived from Quine's naturalized epistemology. ..

This short paper grew out of an observation—made in the course of a larger research project—of a surprising convergence between, on the one hand, certain themes in the work of Mary Hesse and Nelson Goodman in the 1950/60s and, on the other hand, recent work on the representational resources of science, in particular regarding model-based representation. The convergence between these more recent accounts of representation in science and the earlier proposals by Hesse and Goodman consists in the recognition that, (...) in order to secure successful representation in science, collective representational resources must be available. Such resources may take the form of (amongst others) mathematical formalisms, diagrammatic methods, notational rules, or—in the case of material models—conventions regarding the use and manipulation of the constituent parts. More often than not, an abstract characterization of such resources tells only half the story, as they are constituted equally by the pattern of (practical and theoretical) activities—such as instances of manipulation or inference—of the researchers who deploy them. In other words, representational resources need to be sustained by a social practice; this is what renders them collective representational resources in the first place. (shrink)

With this third edition of Nelson Goodman's The Structure of Appear ance, we are pleased to make available once more one of the most in fluential and important works in the philosophy of our times. Professor Geoffrey Hellman's introduction gives a sustained analysis and appreciation of the major themes and the thrust of the book, as well as an account of the ways in which many of Goodman's problems and projects have been picked up and developed by others. Hellman (...) also suggests how The Structure of Appearance introduces issues which Goodman later continues in his essays and in the Languages of Art. There remains the task of understanding Good man's project as a whole; to see the deep continuities of his thought, as it ranges from logic to epistemology, to science and art; to see it therefore as a complex yet coherent theory of human cognition and practice. What we can only hope to suggest, in this note, is the b. road Significance of Goodman's apparently technical work for philosophers, scientists and humanists. One may say of Nelson Goodman that his bite is worse than his bark. Behind what appears as a cool and methodical analysis of the conditions of the construction of systems, there lurks a radical and disturbing thesis: that the world is, in itself, no more one way than another, nor are we. It depends on the ways in which we take it, and on what we do. (shrink)

The Clarke/Rowe version of the Cosmological Argument is sound only if the Principle of Sufficient Reason is true, but many philosophers, including Rowe, think that there is not adequate evidence for the principle of sufficient reason.

To show this, I argue that all the other (...) justifications of the Principle of Universalizability on offer, including Richard Hare's, are inadequate. (shrink)

Philosophical Papers, Volume 40, Issue 3, Page 279-283, November 2011.

So often deployed as a jingoistic, even menacing rallying cry, or limited by a focus on passing moments of liberation, the rhetoric of freedom both rouses and repels. Does it remain key to autonomy, justice, and well-being, or is freedom's long star turn coming to a close? Does a continued obsession with it enliven and emancipate, or reflect a deepening nihilism (or both)? On Freedom examines such questions by tracing the concept's complexities in four realms: art, sex, drugs, and climate. (...) Drawing on a vast range of material, Maggie Nelson explores how we might think, experience, or talk about freedom in ways responsive to the conditions of our day. Her abiding interest lies in ongoing "practices of freedom" by which we negotiate our interrelation with others, with all the care and constraint that entails, while accepting difference and conflict as integral to our communion. As with all of Nelson's work, how she thinks-and how that thinking expresses itself in style-is crucial to the book's achievement. Through her generosity, rigor, and willingness to critically engage reigning pieties, Nelson shows that new forms of thinking and talking are available to us, ones that welcome a chorus of voices, and recommit us to our entanglement, even at its most difficult. On Freedom is an ambitious, essential book that reinvigorates the art of criticism. (shrink)

There are many important methodological decisions that need to be made when examining emotional reactivity in psychopathology. In the present study, we examined the effects of two such decisions in an investigation of emotional reactivity in depression: (1) which (if any) comparison condition to employ; and (2) how to define change. Depressed (N = 69) and control (N = 37) participants viewed emotion-inducing film clips while subjective and facial responses were measured. Emotional reactivity was defined using no comparison condition (i.e., (...) raw scores), baseline comparison condition (i.e., no stimulus presented), and neutral comparison condition (i.e., neutral stimulus presented). Change in emotional reactivity was assessed using four analytic approaches: difference scores, percentage change, residualised change, and ANCOVA. Results differed among the three comparison conditions and among several of the analytic approaches. Overall, our investigation suggests that choosing a comparison condition and the definition of change can significantly influence the presence of group differences in emotional reactivity. Recommendations for studies of emotional reactivity in psychopathology are discussed. (shrink)

The primary intention of this book is to elucidate the relations between sensory perception and art as a form of knowledge. This enables us to understand how different kinds of art are given their meaning not only from observation, resemblance and reason but also from an artist’s sensitivity to the inner form of sensory experience as it is realized in perception, reflection, memory and imagination. By assuming a number of different points of view, Part 1 shows how the physical object (...) and the act of sensory perception are logically interdependent, and I give my elaboration of this argument two kinds of emphasis. In the first place, it opposes all arguments that support a merging of the mental and physical, as in idealism, materialism, neutral monism and panpsychism. A conceptual distinction is observed because sensory perception gives the physical object its identity. This idea also implies that the physical object is only realized by sentient life - self-aware inner life and a world become possible simultaneously. The second emphasis concerns the mind-body problem, and towards the end of Part 1 I offer an argument which places this problem in a certain light by representing the brain not as a physical counterpart to inner experience but as essentially instrumental to perception and self-awareness, and related experience. The argument in Part 2 is distinguished by a sense of continuity between the nature of sensory perception and the formal resources of artists in both physical and literary media. Hence, in a discussion of Titian’s Assumption of the Virgin, I indicate ways in which the painter conveys the inner experience and character of the figures in the painting by means of compositional design, light and colour, and thereby uses these and other sensuous resources to portray human life and experience. This is followed by a discussion of two sonnets by Shakespeare, in which the same general aim is pursued by using the literary resources of figurative language. Finally, a discussion of Hamlet shows how, in this work, the augmentation of figurative language by dramatic form strengthens the view that art can provide a form of knowledge that is based as completely upon intuition about our sensory experience as it is upon reason and observation. Just as my (true) perception of a cup as a vessel for drinking tea or coffee arises immediately from past experience, so the dramatist can see immediately from his or her past experience how a character might perceive things and behave. -/- .

In this manuscript, the author demonstrates how a new idea of the future came into being in eighteenth-century France with the development of modern biological, economic, and social engineering. With the emergence of these practices, the future transformed from something that was largely believed to be predetermined and beyond significant human intervention into something that could be significantly affected through actions in the present. Focusing on the second-half of the century, The author argues that specific mechanisms for constructing the future (...) first arose through the development of practices and instruments aimed at countering degeneration. In their attempts to regenerate a healthy natural state, Enlightenment philosophes created the means to exceed previously recognized limits and create a future that was not merely a recuperation of the past, but was fundamentally different from it. The new active orientation to the future that emerged from these practices was not something that was explicitly articulated during the Enlightenment. Instead this practical orientation must be seen as an implicit understanding of historical temporality. Historical actors often had a tacit knowledge of time--one that they worked with--without necessarily being fully aware of it or articulating it explicitly in their writing. The full articulation of the new idea of the future did not occur until the French Revolution, but the practical understanding of it that developed during the Enlightenment played an important role in making possible the French revolutionaries' unprecedented attempts to remake the world completely anew.

Presented as a Vorlesung in the German philosophical tradition, this book presents the most detailed account of Nelson's method of argument analysis, celebrated by many luminaries such as Karl Popper. It was written in 1921 in opposition to the relativistic, subjectivistic and nihilistic tendencies of Nelson's time. The book contains an exposition of a method that is a further development of Kant's transcendental dialectics, followed by an application to the critical analysis of arguments by many famous thinkers, including (...) Bentham, Mill, Poincaré, Leibniz, Hegel, Einstein, Bergson, Rickert, Simmel, Brentano, Stammler, Jellinek, Dingler, and Meinong. The book presents a general theory of philosophical argumentation as seen from the viewpoint of the typical fallacies committed by anybody arguing philosophically, whether professional philosophers or philosophical laypeople. Although the nature of philosophy and philosophical argumentation is one of the most recurrent objects of reflection for philosophers, this book represents the first attempt at a general theory of philosophical fallacy. According to Nelson, it is in the shape of false dilemmas that errors in reasoning always emerge, and false dilemmas are always the result of the same mechanism--the unwitting replacement of one concept for another.

Miller (1956) summarized evidence that people can remember about seven chunks in short-term memory (STM) tasks. However, that number was meant more as a rough estimate and a rhetorical device than as a real capacity limit. Others have since suggested that there is a more precise capacity limit, but that it is only three to five chunks. The present target article brings together a wide variety of data on capacity limits suggesting that the smaller capacity limit is real. Capacity limits (...) will be useful in analyses of information processing only if the boundary conditions for observing them can be carefully described. Four basic conditions in which chunks can be identified and capacity limits can accordingly be observed are: (1) when information overload limits chunks to individual stimulus items, (2) when other steps are taken specifically to block the recoding of stimulus items into larger chunks, (3) in performance discontinuities caused by the capacity limit, and (4) in various indirect effects of the capacity limit. Under these conditions, rehearsal and long-term memory cannot be used to combine stimulus items into chunks of an unknown size; nor can storage mechanisms that are not capacity-limited, such as sensory memory, allow the capacity-limited storage mechanism to be refilled during recall. A single, central capacity limit averaging about four chunks is implicated along with other, noncapacity-limited sources. The pure STM capacity limit expressed in chunks is distinguished from compound STM limits obtained when the number of separately held chunks is unclear. Reasons why pure capacity estimates fall within a narrow range are discussed and a capacity limit for the focus of attention is proposed. Key Words: attention; enumeration; information chunks; memory capacity; processing capacity; processing channels; serial recall; short-term memory; storage capacity; verbal recall; working memory capacity.

In response to Jürgen Habermas’s critical assessment of the import of Theodor Adorno’s aesthetics, I revisit Adorno’s aesthetics in the context of the question of whether and to what extent there can be an aesthetics of nature, and the potential ethical and social-political significance of such an aesthetics.
