We provide an introduction to network theory, evidence to support a connection between molecular network structure and neuropsychiatric disease, and examples of how network approaches can expand our knowledge of the molecular bases of these diseases. Without systematic methods to derive their biological meanings and inter‐relatedness, the many molecular changes associated with neuropsychiatric disease, including genetic variants, gene expression changes, and protein differences, present an impenetrably complex set of findings. Network approaches can potentially help integrate and reconcile these findings, as (...) well as provide new insights into the molecular architecture of neuropsychiatric diseases. Network approaches to neuropsychiatric disease are still in their infancy, and we discuss what might be done to improve their prospects. (shrink)

In this paper I briefly summarize Pellegrino’s phenomenological analysis of the ethics of the physician–patient relationship. In delineating the essential elements of the healing relationship, Pellegrino demonstrates the necessity for health care professionals to understand the patient’s lived experience of illness. In considering the phenomenon of illness, I identify certain essential characteristics of illness-as-lived that provide a basis for developing a rigorous understanding of the patient’s experience. I note recent developments in the systematic delivery of health care that make it (...) difficult for health care professionals to realize Pellegrino’s ethical model of the role of healer. Such developments limit both the physician’s freedom to act on behalf of the patient without the constraint of third parties and the physician’s freedom to act in light of his or her own ethical or religious convictions. Given these difficulties, I note MacIntyre’s call for the development of moral communities, as an alternative to the prevailing culture, and share a first-hand example illustrating how intentional Christian community provides an alternative nurturing context that permits the full development of the healing relationship.

Yet, the central conviction that informs this volume is that phenomenology provides extraordinary insights into many of the issues that are directly addressed ...

This essay argues that, while much has been gained by medicine's focus on the spatial aspects of disease in light of developments in modern pathology, too little attention has been given to the temporal experience of illness at the subjective level of the patient. In particular, it is noted that there is a radical distinction between subjective and objective time. Whereas the patient experiences his immediate illness in terms of the ongoing flux of subjective time, the physician conceptualizes the illness (...) as a disease state according to the measurements of objective time. A greater understanding of this disparity in temporal experiencing provides insights into the lived experience of illness and can preclude difficulties in communication between physician and patient.

Book reviewed in this article: The Meaning of Illness. By S. Kay Toombs.

In this essay I discuss Edith Stein's analysis of empathy and note its application in the field of clinical medicine. In identifying empathy as the basic mode of cognition in which one grasps the experiences of others, Stein notes, 'I grasp the Other as a living body and not merely as a physical body'. The living body is given in terms of five distinctive characteristics - characteristics that disclose important facets of the illness experience. Empathy plays an important role in (...) clinical practice in aiding physicians to grasp the content of first-person reports of bodily disorder, and to comprehend the meaning of illness-as-lived. I suggest that an important task for medical education should be that of developing students' capacity for empathic understanding and I note several ways in which this task might be accomplished.

"--Joel Cracraft, American Museum of Natural History "This is not the potted history that one usually finds in texts and review articles.

Features Covers the philosophical and historical development of the concept of "species" Documents that variation was recognized by pre-Darwinian scholars Includes a section on the debates since the time of the New Synthesis Better suited to non-philosophers Summary Over time the complex idea of "species" has evolved, yet its meaning is far from resolved. This comprehensive work is a fresh look at an idea central to the field of biology by tracing its history from antiquity to today. Species is a (...) benchmark exploration and clarification of a concept fundamental to the past, present, and future of the natural sciences. In this edition, a section is added on the debate over species since the time of the New Synthesis, and brings the book up to date. A section on recent philosophical debates over species has also been added. This edition is better suited non-specialists in philosophy, so that it will be of greater use for scientists wishing to understand how the notion came to be that living organisms form species.

In this paper I reflect upon my personal experience of chronic progressive multiple sclerosis in order to provide a phenomenological account of the human experience of disability. In particular, I argue that the phenomenological notion of lived body provides important insights into the profound disruptions of space and time that are an integral element of changed physical capacities such as loss of mobility. In addition, phenomenology discloses the emotional dimension of physical disorder. The lived body disruption engendered by loss of (...) mobility includes a change in the character of surrounding space, an alteration in one's taken-for-granted awareness of objects, the disruption of corporeal identity, a disturbance in one's relations with others, and a change in the character of temporal experience. The loss of upright posture is of particular significance since it not only concretely diminishes autonomy but affects the way one is treated by others. Such a change in posture is, therefore, particularly disruptive in the social world of everyday life. An understanding of the lived body disruption engendered by disability has important applications for the clinical context in devising effective therapies, as well as for the social arena in determining how best to resolve the various challenges posed by chronic disabling disorders.

A hypothesis on the evolutionary origin of the genetic pathway of sex determination in the nematode Caenorhabditis elegans is presented here. It is suggested that the pathway arose in steps, driven by frequency‐dependent selection for the minority sex at each step, and involving the sequential acquisition of dominant negative, neomorphic genetic switches, each one reversing the action of the previous one. A central implication is that the genetic pathway evolved in reverse order from the final step in the hierarchy up (...) to the first. The possible applicability of the model to the other well‐characterized sex determination pathway, that of Drosophila melanogaster, and to sex determination in mammals, is discussed, along with some potential implications for pathway evolution in general. Finally, the specific molecular and population genetic questions that the model raises are described and some tests are proposed. (shrink)

Over the past few years, blogging (“web logging”) has become a major social movement, and as such includes blogs by scientists about science. Blogs are highly idiosyncratic, personal and ephemeral means of public expression, and yet they contribute to the current practice and reputation of science as much as, if not more than, any popular scientific work or visual presentation. It is important, therefore, to understand this phenomenon.
