Roger Williams est l’un des créateurs de la tradition constitutionnelle américaine. Il fournit les bases d’une politique fondée sur un égal respect des consciences et l’équité religieuse qui résonnent jusqu’à aujourd’hui. Derrière son importante réussite politique, il y a une pensée aussi riche sur ces questions que celle de John Locke et nettement plus pénétrante quant à la psychologie de la victime et de son tortionnaire. Elle tourne autour d’une idée sur laquelle Williams se concentre avec un zèle obsessionnel : (...) la notion du prix et de la dignité de la conscience individuelle de l’homme. Il aide à voir pourquoi la persécution est si tentante et quelles attitudes émotionnelles pourraient être exigées pour lui résister. En développant en outre un compte rendu élaboré des compétences convenables aux autorités civiles et religieuses, il anticipe la position la plus célèbre de Locke. Il n’est pas extravagant d’y voir une esquisse de la notion de John Rawls d’une société civile impliquant un ensemble de principes moraux à propos desquels des gens avec des « doctrines complètes » peuvent se rejoindre dans un « consensus qui se chevauche ».

Since the 1930s, scientists studying the neurological disease scrapie had assumed that the infectious agent was a virus. By the mid 1960s, however, several unconventional properties had arisen that were difficult to reconcile with the standard viral model. Evidence for nucleic acid within the pathogen was lacking, and some researchers considered the possibility that the infectious agent consisted solely of protein. In 1982, Stanley Prusiner coined the term `prion' to emphasize the agent's proteinaceous nature. This infectious protein hypothesis was denounced (...) by many scientists as `heretical'.This essay asks why the concept of an infectious protein was considered controversial. Some biologists justified their evaluation of this hypothesis on the grounds that an infectious protein contradicted the `central dogma of molecular biology'. Others referred to vague theoretical constraints such as molecular biology's `theoretical structure' or `framework'. Examination of the objections raised by researchers reveals exactly what generalizations were being challenged by a protein model of infection.This two-part survey of scrapie and prion research reaches several conclusions: A theoretical framework is present in molecular biology, exerting its influence in hypothesis formation and evaluation; This framework consists of several related, yet separable, generalizations or `elements', including Francis Crick's Central Dogma and Sequence Hypothesis, plus notions concerning infection, replication, protein synthesis, and protein folding; The term `central dogma' has stretched beyond Crick's original 1958 definition to encompass at least two other `framework elements': replication and protein synthesis; and From the study of scrapie and related diseases, biological information has been delineated into at least two classes: sequential and what I call `conformational'.In Part I of this essay, a brief review of the central dogma, as outlined by both Francis Crick and James Watson, will be given. The developments in scrapie research from 1965 to 1972 will then be traced. This section will summarize many of the puzzling, non-viral-like properties of the scrapie agent. Alternative hypotheses to the viral explanation will also be presented, including early versions of a protein-only hypothesis. Part II of this essay will follow the developments in scrapie and prion research from the mid 1970s through 1991. The growing prominence of a protein-only model of infection will be balanced by continued objections from many researchers to a pathogen devoid of nucleic acid. These objections will help illuminate those generalizations in molecular biology that were indeed challenged by a protein-only model of infection. (shrink)

The developing infant can accomplish all important perceptual tasks that an adult can, albeit with less skill or precision. Through infant perception research, infant responses to experiences enable researchers to reveal perceptual competence, test hypotheses about processes, and infer neural mechanisms, and researchers are able to address age-old questions about perception and the origins of knowledge.In Development of Perception in Infancy: The Cradle of Knowledge Revisited, Martha E. Arterberry and Philip J. Kellman study the methods and data of scientific (...) research on infant perception, introducing and analyzing topics through philosophical, theoretical, and historical contexts. Infant perception research is placed in a philosophical context by addressing the abilities with which humans appear to be born, those that appear to emerge due to experience, and the interaction of the two. The theoretical perspective is informed by the ecological tradition, and from such a perspective the authors focus on the information available for perception, when it is used by the developing infant, the fit between infant capabilities and environmental demands, and the role of perceptual learning. Since the original publication of this book in 1998, Arterberry and Kellman address in addition the mechanisms of change, placing the basic capacities of infants at different ages and exploring what it is that infants do with this information. Significantly, the authors feature the perceptual underpinnings of social and cognitive development, and consider two examples of atypical development - congenital cataracts and Autism Spectrum Disorder. Professionals and students alike will find this book a critical resource to understanding perception, cognitive development, social development, infancy, and developmental cognitive neuroscience, as research on the origins of perception has changed forever our conceptions of how human mental life begins.

There is an abundant and growing feminist literature examining the implications of reproductive technologies that separate genetic, physiological, and social motherhood. The literature explains the development of these technologies in terms of the motivations of men (scientists, doctors, lawyers, “pharmacrats,”“technodocs,” etc.), stressing the victimization of women by the medical and legal institutions and the commodification of these technologies. This article examines these technologies from a Marxist-Feminist perspective, locating their sources in the overall development of the forces of production; that is, (...) in structural changes irreducible to their microfoundations. In the process of changing the biological conditions of intergenerational social reproduction, these technologies have established the material basis for the structural separation between the mode of procreation (open to public scrutiny, medical intervention, and state supervision) and the mode of social and physical reproduction (which functions in the privacy of households). These structural changes are generating new identities and forms of consciousness that clash with taken-for-granted ideas about motherhood. These differences are captured in feminist debates about the significance of these technologies. (shrink)

The “Perky effect” is the interference of visual imagery with vision. Studies of this effect show that visual imagery has more than symbolic properties, but these properties differ both spatially (including “pictorially”) and temporally from those of vision. We therefore reject both the literal picture-in-the-head view and the entirely symbolic view.

Developmental research on infants' categorization of living and nonliving objects finds that very young children are equally skilled in grouping such objects. The lack of a specialization for one type of object over another may be due to knowledge of function and the time frame for acquiring such knowledge.

The cognitive disorders that follow brain damage are an important source of insights into the neural bases of human thought. This work offers state-of-the-art reviews of the patient-based approach to central issues in cognitive neuroscience by leaders in the field.

Meditation is an umbrella term for a number of mental training practices designed to improve the monitoring and regulation of attention and emotion. Some forms of meditation are now being used for clinical intervention. To accompany the increased clinical interest in meditation, research investigating the neural basis of these practices is needed. A central hypothesis of contemplative neuroscience is that meditative states, which are unique on a phenomenological level, differ on a neurophysiological level. To identify the electrophysiological correlates of meditation (...) practice, the electrical brain activity of highly skilled meditators engaging in one of six meditation styles was recorded. A mind-wandering task served as a control. Lempel–Ziv complexity showed differences in nonlinear brain dynamics during meditation compared with mind wandering, suggesting that meditation, regardless of practice, affects neural complexity. In contrast, there were no differences in power spectra at six different frequency bands, likely due to the fact that participants engaged in different meditation practices. Finally, exploratory analyses suggest neurological differences among meditation practices. These findings highlight the importance of studying the electroencephalography correlates of different meditative practices. (shrink)

The study of politics seems endlessly beset by debates about method. At the core of these debates is a single unifying concern: should political scientists view themselves primarily as scientists, developing ever more sophisticated tools and studying only those phenomena to which such tools may fruitfully be applied? Or should they instead try to illuminate the large, complicated, untidy problems thrown up in the world, even if the chance to offer definitive explanations is low? Is there necessarily a tension between (...) these two endeavours? Are some domains of political inquiry more amenable to the building up of reliable, scientific knowledge than others, and if so, how should we deploy our efforts? In this book, some of the world's most prominent students of politics offer original discussions of these pressing questions, eschewing narrow methodological diatribes to explore what political science is and how political scientists should aspire to do their work.

This paper contributes to the foundations of a theory of rational choice for artificial agents in dynamic environments. Our work is developed within a theoretical framework, originally due to Bratman, that models resource-bounded agents as operating against the background of some current set of intentions, which helps to frame their subsequent reasoning. In contrast to the standard theory of rational choice, where options are evaluated in isolation, we therefore provide an analysis of situations in which the options presented to an (...) agent are evaluated against a background context provided by the agent’s current plans—commitments to future activities, which may themselves be only partially specified. The interactions between the new options and the background context can complicate the task of evaluating the option, rendering it either more or less desirable in context than it would have been in isolation.  2001 Elsevier Science B.V.

Aim: Explore nurses’ values and perceptions regarding the practice of medical aid in dying. Background: Medical aid in dying is becoming increasing legal in the United States. The laws and American Nurses Association documents limit nursing involvement in this practice. Nurses’ values regarding this controversial topic are poorly understood. Methodology: Cross-sectional electronic survey design sent to nurse members of the American Nurses Association. Inductive thematic content analysis was applied to open-ended comments. Ethical Considerations: Approved by the institutional review board (#191046). (...) Participants: 1213 nurses provided 3639 open-ended comments. More than 80% of participants self-identified as white 58% held a graduate degree; and half were of Christian faith. Results: Values ranged on a continuum expressed through four themes: “Honoring Patient Autonomy without Judgment,” “Honoring with Limitations,” “Not until...,” and “Adamantly against.” Some felt it was a duty to honor the patients’ wishes, set aside own beliefs, and respect patients’ choices often with a spiritual connotation. Nurses held concerns about the process, policy, potential psychological harm, legal risk, and the need to learn more about MAID. Nurse who were adamantly against MAID associated the practice with murder/suicide and against religious beliefs. Disparate values were expressed about changing the MAID legislation to allow patient support with taking MAID medications and allowing MAID via advance directive. Conclusions: Nurses desire more education on MAID. There is not one universally held position on the nurse’s role during MAID. Healthcare policy/standards need to accommodate the wide variation in nurses’ values. Implications: Nurses desire education regarding their role in MAID. Nurses are encouraged to participate in policy discussions as the practice becomes increasingly legal. Managers need to expect that nurses, patients, and families will need psychological support to participate in MAID. Careful construction of policy/standards is needed to minimize conflict, moral distress, and psychological harm amongst nurses. Further research is needed. (shrink)

ABSTRACTAnxiety and depression diagnoses are associated with suicidal thoughts and behaviours. However, a categorical understanding of these associations limits insight into identifying dimensional mechanisms of suicide risk. This study investigated anxious and depressive features through a lens of suicide risk, independent of diagnosis. Latent class analysis of 97 depression, anxiety, and suicidality-related items among 616 psychiatric outpatients indicated a 3-class solution, specifically: a higher suicide-risk class uniquely differentiated from both other classes by high reported levels of depression and anxious arousal; (...) a lower suicide-risk class that reported levels of anxiety sensitivity and generalised worry comparable to Class 1, but lower levels of depression and anxious arousal; and a low to non-suicidal class that reported relatively low levels across all depression and anxiety measures. Discriminants of the higher suicide-risk class included borderline personality disorder; report... (shrink)
