The generalized second law of thermodynamics states that entropy always increases when all event horizons are attributed with an entropy proportional to their area. We test the generalized second law by investigating the change in entropy when dust, radiation and black holes cross a cosmological event horizon. We generalize for flat, open and closed Friedmann–Robertson–Walker universes by using numerical calculations to determine the cosmological horizon evolution. In most cases, the loss of entropy from within the cosmological horizon is more than (...) balanced by an increase in cosmological event horizon entropy, maintaining the validity of the generalized second law of thermodynamics. However, an intriguing set of open universe models shows an apparent entropy decrease when black holes disappear over the cosmological event horizon. We anticipate that this apparent violation of the generalized second law will disappear when solutions are available for black holes embedded in arbitrary backgrounds. (shrink)

The Greek & Latin Roots of English approaches the study of Latin and Greek thematically: vocabulary is organized into various topics, from politics to philosophy, with chapters featuring cumulative exercises and notes to help students learn the pleasures of language study. The fifth edition features revised exercises, alphabetical vocabulary lists, and more.

Obtaining informed consent, an ethical obligation of nurses and other health care providers, occurs routinely when patients make health care decisions. The values underlying informed consent (promotion of patients’ well-being and respect for their self-determination) are embedded in the dominant American culture. Nurses who apply the USA’s cultural values of informed consent when caring for patients who come from other cultures encounter some ethical dilemmas. This descriptive study, conducted with Latino, Chinese and Anglo-American cancer patients in a large, public, west-coast (...) clinic, describes constraints on the informed consent process in a multicultural setting, including language barriers, the clinical environment, control in decision making, and conflicting desired health outcomes for health care providers and patients, and suggests some implications for nursing practice.

Modified Theistic Activism is the view that abstract objects not essentially possessed by God fall under God’s creative activity in one way or another. Michelle Panchuk has argued that this position succumbs to the bootstrapping problem such that God is and is not logically prior to his properties—an incoherent and necessarily false state of affairs. In this essay we respond to Panchuk by arguing that our neo-Aristotelian account of substance and property possession successfully avoids the bootstrapping problem. Moreover, her own (...) neo-Augustinian account of universals contains many conceptual deficiencies and ultimately succumbs to an epistemic iteration of the bootstrapping problem. Finally, we argue that the reasons provided for thinking only created beings need universals to ground character is unmotivated. In clarifying and defending our position, our hope is to bury once and for all the familiar claim that traditional theists cannot be realists with respect to abstract objects because of divine bootstrapping.

Recent magnetic resonance imaging and pathological studies have indicated that axonal loss is a major contributor to disease progression in multiple sclerosis. 1 H magnetic resonance spectroscopy, through measurement of N -acetyl aspartate, a neuronal marker, provides a unique tool to investigate this. Patients with primary progressive multiple sclerosis have few lesions on conventional MRI, suggesting that changes in normal appearing white matter, such as axonal loss, may be particularly relevant to disease progression in this group. To test this hypothesis (...) NAWM was studied with MRS, measuring the concentration of N -acetyl derived groups. Single-voxel MRS using a water-suppressed PRESS sequence was carried out in 24 patients with primary progressive multiple sclerosis and in 16 age-matched controls. Ratios of metabolite to creatine concentration were calculated in all subjects, and absolute concentrations were measured in 18 patients and all controls. NA/Cr was significantly lower in NAWM in patients than in controls, as was the absolute concentration of NA. There was no significant difference in the absolute concentration of creatine between the groups. This study supports the hypothesis that axonal loss occurs in NAWM in primary progressive multiple sclerosis and may well be a mechanism for disease progression in this group. (shrink)

Recent public hearings on misconduct charges belie the conjecture that due process will perforce defeat informed scientific reasoning. One notable case that reviewed an obtuse description of experimental methods displays some of the subtleties of differentiating carelessness from intent to deceive. There the decision of a studious nonscientist panel managed to reach sensible conclusions despite conflicting expert testimony. The significance of such a result may be to suggest that to curtail due process would be both objectionable and unproductive.

Although women are severely under-represented in national politics in Europe, in the European Parliament they are better represented than they are in the national parliaments of the EEC member states. This book examines why this is so. Based largely on their detailed interviews with women MEPs, the authors describe the latter's backgrounds, attitudes and political experience. They also explain the history, structure and organisation of the European Parliament and outline the complexities of the European legal system. A particular concern of (...) the book is the contribution that women MEPs have made to legislation and policy, expecially in the context of recent Community legislation on sex equality, and what impact their presence has had on issues relating to women's interests.

In this introduction to Part 1 of the Common Knowledge symposium, “Fuzzy Studies,” the journal's editor discusses four essays from the 1980s by Richard Rorty, in which Rorty chose to associate himself with various neopragmatists, Continental thinkers, and “left-wing Kuhnians” under the rubric of the “new fuzziness.” The term had been introduced as an insult by a philosopher of science with positivist leanings, but Rorty took it up as an “endearing” compliment, arguing that “to be less fuzzy” was also to (...) be “less genial, tolerant, open-minded, and fallibilist.” He defined the “new fuzziness” as “an attempt to blur just those distinctions between the objective and subjective and between fact and value which the critical conception of rationality has developed.” This introduction also examines W. V. Quine's essay “Speaking of Objects”, which describes objects as fuzzy “half-entities”; Clifford Geertz's essay “Blurred Genres”, which advises social scientists that being “taxonomically upstanding” is futile; and Lofti Zadeh's article “The Concept of a Linguistic Variable and Its Application to Approximate Reasoning”, which abandons “Aristotelian, bivalent logic” in favor of a “fuzzy logic” based on Zadeh's “fuzzy set theory.” This introductory piece relates these theoretical works of the past half-century to the sorites paradox and to classical issues of vagueness raised and still unresolved in Western philosophy. Returning then to Rorty, the author questions how Rorty expected his endorsement of the “new fuzziness” to be applied, as proposed, to theology and politics. Suggesting that such applications are the natural work of historians, the author, having asked the historian Natalie Zemon Davis for comment, then quotes her response—which associates fuzzy studies, “common knowledge,” and peacemaking—at length.

After introducing the new field of cultural evolution, we review a growing body of empirical evidence suggesting that culture shapes what people attend to, perceive and remember as well as how they think, feel and reason. Focusing on perception, spatial navigation, mentalizing, thinking styles, reasoning (epistemic norms) and language, we discuss not only important variation in these domains, but emphasize that most researchers (including philosophers) and research participants are psychologically peculiar within a global and historical context. This rising tide of (...) evidence recommends caution in relying on one’s intuitions or even in generalizing from reliable psychological findings to the species, Homo sapiens. Our evolutionary approach suggests that humans have evolved a suite of reliably developing cognitive abilities that adapt our minds, information-processing abilities and emotions ontogenetically to the diverse culturally-constructed worlds we confront.

Philosophy and Christianity make truth claims about many of the same things. They both claim to provide answers to the deep questions of life. But how are they related to one another? Four Views on Christianity and Philosophy introduces readers to four predominant views on the relationship between philosophy and the Christian faith and their implications for life. Each author identifies the propositional relation between philosophy and Christianity along with a section devoted to the implications for living a life devoted (...) to the pursuit of wisdom. -/- The contributors and views include: -/- Graham Oppy—Conflict: Philosophy Trumps Christianity K.

The typical Cartesian collection contains papers which treat the problems arising out of Descartes's philosophy as though they and it appeared for the first time in a recent journal. The approach of this collection is quite different. The eight contributors concentrate on problems faced by Cartesianism which are of historical significance. Without denigrating the importance of the technique of exploiting the texts in a manner that appeals to contemporary philosophical interests, the contributors show how Cartesianism was shaped over time by (...) the criticism it received. This criticism took place in many areas - politics, theology, natural science, and metaphysics - and its scope is reflected in this collection of papers. The efforts of advocates of Cartesianism to produce a biography of Descartes, and the political difficulties they faced, are no less a part of the problems of Cartesianism than are the difficulties alleged against the Cartesian ontology of thought and extension in accounting for transubstatiation. Seventeenth- and eighteenth-century theories of the formation of the earth, for example, were historically part of the same set of problems as the difficulties in Bible criticism. These significant issues and many others are discussed in this volume. (shrink)

A simple experimental paradigm creates the powerful illusion that one is touching one’s own hand even when the two hands are separated by 15 cm. The participant uses her right hand to administer stimulation to a prosthetic hand while the Examiner provides identical stimulation to the participant’s receptive left hand. Change in felt position of the receptive hand toward the prosthetic hand has previously led to the interpretation that the participant experiences self-touch at the location of the prosthetic hand, and (...) experiences a sense of ownership of the prosthetic hand. Our results argue against this interpretation. We assessed change in felt position of the participant’s receptive hand but we also assessed change in felt position of the participant’s administering hand. Change in felt position of the administering hand was significantly greater than change in felt position of the receptive hand. Implications for theories of ownership are discussed. (shrink)

Advances in genomics have led to calls for developing population-based preventive genomic sequencing programs with the goal of identifying genetic health risks in adults without known risk factors. One critical issue for minimizing the harms and maximizing the benefits of PGS is determining the kind and degree of control individuals should have over the generation, use, and handling of their genomic information. In this article we examine whether PGS programs should offer individuals the opportunity to selectively opt out of the (...) sequencing or analysis of specific genomic conditions or whether PGS should be implemented using an all-or-nothing panel approach. We conclude that any responsible scale-up of PGS will require a menu approach that may seem impractical to some, but that draws its justification from a rich mix of normative, legal, and practical considerations.

While somatic cell editing to treat disease is widely accepted, the use of human genome editing for “enhancement” remains contested. Scientists and policy-makers routinely cite the prospect of enhancement as a salient ethical challenge for human genome editing research. If preventive genome editing projects are perceived as pursuing human enhancement, they could face heightened barriers to scientific, public, and regulatory approval. This article outlines what we call “preventive strengthening research” (or “PSR”) to explore, through this example, how working to strengthen (...) individuals’ resistance to disease beyond what biomedicine considers to be the human functional range may be interpreted as pursuing human enhancement. Those involved in developing guidance for PSR will need to navigate the interface between preventive goals and enhancement implications. This article identifies and critiques three of these ideas in the interest of anticipating the wider emergence of PSR and the need for a normative approach for its pursuit. All three “candidate criteria” merit attention, but each also faces challenges that will need to be addressed as further research policy is developed. (shrink)

Background: The Declaration of Helsinki, the World Medical Association’s statement of ethical guidelines regarding medical research, is published in the three official languages of the WMA: English, French and Spanish.Methods: A detailed comparison of the three official language versions was carried out to determine ways in which they differed and ways in which the wording of the three versions might illuminate the interpretation of the document.Results: There were many minor linguistic differences between the three versions. However, in paragraphs 1, 6, (...) 29, 30 and in the note of clarification to paragraph 29, there were differences that could be considered potentially significant in their ethical relevance.Interpretation: Given the global status of the Declaration of Helsinki and the fact that it is translated from its official versions into many other languages for application to the ethical conduct of research, the differences identified are of concern. It would be best if such differences could be eliminated but, at the very least, a commentary to explain any differences that are unavoidable on the basis of language or culture should accompany the Declaration of Helsinki. This evidence further strengthens the case for international surveillance of medical research ethics as has been proposed by the WMA. (shrink)

Although medical providers rely on similar tools to “treat” intersex and trans individuals, their enactment of medicalization practices varies. To deconstruct these complexities, we employ a comparative analysis of providers who specialize in intersex and trans medicine. While both sets of providers tend to hold essentialist ideologies about sex, gender, and sexuality, we argue they medicalize intersex and trans embodiments in different ways. Providers for intersex people are inclined to approach intersex as an emergency that necessitates medical attention, whereas providers (...) for trans people attempt to slow down their patients’ urgent requests for transitioning services. Building on conceptualizations of “giving gender,” we contend both sets of providers “give gender” by “giving sex.” In both cases too, providers shift their own responsibility for their medicalization practices onto others: parents in the case of intersex, or adult recipients of care in the case of trans. According to the accounts of most providers, successful medical interventions are achieved when a person adheres to heteronormative gender practices. (shrink)

The growing practice of returning individual results to research participants has revealed a variety of interpretations of the multiple and sometimes conflicting duties that researchers may owe to participants. One particularly difficult question is the nature and extent of a researcher’s duty to facilitate a participant’s follow-up clinical care by placing research results in the participant’s medical record. The question is especially difficult in the context of genomic research. Some recent genomic research studies — enrolling patients as participants — boldly (...) address the question with protocols dictating that researchers place research results directly into study participants’ existing medical records, without participant consent. Such privileging of researcher judgment over participant choice may be motivated by a desire to discharge a duty that researchers perceive themselves as owing to participants. However, the underlying ethical, professional, legal, and regulatory duties that would compel or justify this action have not been fully explored. (shrink)

The evidence linking tobacco product advertising to adolescent smoking initiation and resulting long-term addiction, premature death, and disability is well established. Each link in the causal chain has been substantiated: children and adolescents are especially vulnerable to advertising; point-of-sale advertising comprises 92.1% of cigarette advertising and marketing expenditures by manufacturers and 71.3% of smokeless tobacco advertising; tobacco companies have targeted youth through advertising; advertising exposure causes adolescents to start and to continue smoking; among adults who become daily smokers, nearly all (...) first use of cigarettes occurs by 18 years of age; adolescents who smoke are at high risk for long-term addiction because their brains are still developing; and long-term addiction results in the tremendous personal, social and financial costs of tobacco-related illnesses.

Inattentional blindness studies have shown that an unexpected object may go unnoticed if it does not share the property specified in the task instructions. Our aim was to demonstrate that observers develop an attentional set for a property not specified in the task instructions if it allows easier performance of the primary task. Three experiments were conducted using a dynamic selective-looking paradigm. Stimuli comprised four black squares and four white diamonds, so that shape and colour varied together. Task instructions specified (...) shape but observers developed an attentional set for colour, because we made the black–white discrimination easier than the square–diamond discrimination. None of the observers instructed to count bounces by squares reported an unexpected white square, whereas two-thirds of observers instructed to count bounces by diamonds did report the white square. When attentional set departs from task instructions, you may fail to see what you were told to look for. (shrink)

Over the past decade, the number of clinical trials registered with the Food and Drug Administration has increased dramatically. The business of clinical research has become more diverse, involving academic institutions, clinician-researchers in community settings, pharmaceutical companies, and contract research organizations. This growth has been accompanied by increasing concerns about the ethical conduct of research. Much of this concern has been directed to procedural issues including institutional review board review, data monitoring, and informed consent forms. However, the protection of human (...) subjects cannot be achieved by relying solely on procedural safeguards. There are more nuanced issues related to recruitment and retention of subjects, and to the process of informed consent, that are generated during the interaction between study staff and subjects. It is only through an examination of these relationships that one can more fully define and understand the challenges of protecting subjects in research. (shrink)
