In this commentary we discuss the possibility of subcortical consciousness and its implications for fetal anesthesia and analgesia. We review the neural development of structural and functional elements that may participate in conscious representation, with a particular focus on the experience of pain.

Considering the organization’s ethical context as a framework to investigate workplace phenomena, this field study of military reserve personnel examines the relationships among perceptions of psychosocial group variables, such as cohesiveness, helping behavior and peer leadership, employee job attitudes, and the likelihood of individuals’ withholding on-the-job effort, a form of organizational misbehavior. Hypotheses were tested with a sample of 290 individuals using structural equation modeling, and support for negative relationships between perceptions of positive group context and withholding effort by individual (...) employees was found. In addition, individual effort-performance expectancy and individual job satisfaction were negatively related to withholding effort. The findings provide evidence that individual perceptions of positive group context play a key role in the presence of misbehavior at work. The results indicate that positive group context might be an important element of ethical climate that should be managed to temper occurrence of such adverse work behavior. (shrink)
Considerable work within the modern 'space-time theory' approach to relativity physics has been devoted to clarifying the role and meaning of the principle of relativity. Two recent discussions of the principle within this approach, due to Arntzenius (1990) and Friedman (1983), are found to contain difficulties.
Abstract The historical evolution of the principle of relativity from Galileo to Einstein is briefly traced, and purported difficulties with Einstein's formulation of the principle are examined and dismissed. This formulation is then compared to a precise version formulated recently in the geometrical language of spacetime theories. We claim that the recent version is both logically puzzling and fails to capture a crucial physical insight contained in the earlier formulations. The implications of this claim for the modern treatment of general (...) dynamical symmetries are discussed. (shrink)
Roland Barthes, the French critic and semiotician, was one of the most important critics and essayists of this century. His work continues to influence contemporary literary theory and cultural studies. Image-Music-Text collects Barthes's best writings on photography and the cinema, as well as fascinating articles on the relationship between images and sound. Two of Barthes's most important essays, "Introduction to the Structural Analysis of Narrative" and "The Death of the Author" are also included in this fine anthology, an excellent (...) introduction to his thought. These essays, as selected and translated by Stephen Heath, are among the finest writings Barthes ever published on film and photography, and on the phenomena of sound and image. The classic pieces "Introduction to the Structural Analysis of Narrative" and "The Death of the Author" are also included. (shrink)
