This paper analyzes communication with a language that is vague in the sense that identical messages do not always result in identical interpretations. It is shown that strategic agents frequently add to this vagueness by being intentionally vague, i.e. they deliberately choose less precise messages than they have to among the ones available to them in equilibrium. Having to communicate with a vague language can be welfare enhancing because it mitigates conflict. In equilibria that satisfy a dynamic stability condition intentional (...) vagueness increases with the degree of conflict between sender and receiver. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Looking to Learn: Museum Educators and Aesthetic EducationNancy Blume (bio), Jean Henning (bio), Amy Herman (bio), and Nancy Richner (bio)IntroductionMuseum education. Aesthetic education. How are they similar? How do they differ? How do they relate to each other? What are their goals? As museum educators working with classroom and art teachers, we are often asked these questions, and we ask them ourselves. “What do you DO?” is probably (...) the most frequently asked question of all, and the answer is complex. Even more complex is how these questions relate to the Rembrandt Project. Given that looking at original works of art is such a priority for museums and museum educators, how do we address the project’s reliance on technology? And how do these questions relate to the social studies and visual arts standards, [End Page 83] another major component of the project? How does the project relate to the work we do in our own museums? Writing collaboratively implies that we have certain areas of commonality; but we also have differences, which will be apparent in individual sections of this article: Jean Henning and Nancy Richner discuss the Nassau County Museum of Art, Nancy Blume writes about Asia Society, and Amy Herman explores the Frick Collection. Our focus will be the domain of museum education as that is what we know best, but there are inevitably areas where it overlaps and complements the domains of art education, aesthetic education, and social studies.Art Museum Education HistoryThe history of art museum education begins with the founding of museums in the United States during the commercial and industrial expansion that took place after the Civil War, between 1870 and 1929. The principles guiding American museums have always mirrored the values of American society. From the beginning of this country’s history, the fine arts have been viewed as elitist and thus of no value to the larger society. “To America,” Ben Franklin wrote in the late 1700s, “one school master is worth a dozen poets, and the invention of a machine or the improvement of an implement is of more importance than a masterpiece of Raphael.”1 Given such longstanding and deep-seated suspicion of art among Americans, it is not surprising that both the champions and the staff of art museums insisted on the practical educational benefits museums provided to the public.By the late nineteenth century, at the height of immigration and the emergence of a strong working class and labor movement, a social dimension was added to the mission of museum education. Art museums, like public libraries, were seen as venues for achieving social balance. By the early twentieth century an aesthetic agenda was finally joined to these social and pragmatic ones.2While museums have responded to the needs created by cyclical changes in social, economic, political, and intellectual life, today’s art museum educators still deal with the tension among the museum’s aesthetic, educational, and social missions; only the context and delivery modes of museum education have changed. Yet despite the shifting directions and priorities in museum education, there are certain basic and commonly accepted premises that museum educators have shared since the late nineteenth century. The 1984 Museums Commission on Museums for a New Century stated what has been the continuing premise of museum education since the late nineteenth century: learning in museums is based on objects and involves not only developing the ability to synthesize ideas and form opinions but also shaping an aesthetic and cultural sensibility.3 Another fundamental [End Page 84] assumption is that museums are institutions of visual instruction. Although each of the museum educators writing here represents a unique institution with unique approaches to looking at and finding meaning in art, we all agree on the importance of the original work of art as the basis for our work. It is the complexity of original artworks that enables them to play a dual role. One role is pragmatic, which requires meeting standards set by state and national governments for teaching critical thinking skills and improving literacy. The second role is aesthetic—namely, ways of helping students develop habits for aesthetic encounters that are an integral part... (shrink)

The process of technological change in obstetrics must be understood as contingent on the exigencies of the professional project, rather than in terms simply of improvement or dehumanization of care. Transformation in the procedures by which the female pelvis and the fetal head have been measured illustrate this point. The development of new measurement techniques was profoundly influenced by the shifting locus of obstetric care and by changing professional concerns, including the initial demarcation of a professional practice and subsequent debates (...) about preferred modes of intervention.

As quantum information science approaches the goal of constructing quantum computers, understanding loss of information through decoherence becomes increasingly important. The information about a system that can be obtained from its environment can facilitate quantum control and error correction. Moreover, observers gain most of their information indirectly, by monitoring (primarily photon) environments of the “objects of interest.” Exactly how this information is inscribed in the environment is essential for the emergence of “the classical” from the quantum substrate. In this paper, (...) we examine how many-qubit (or many-spin) environments can store information about a single system. The information lost to the environment can be stored redundantly, or it can be encoded in entangled modes of the environment. We go on to show that randomly chosen states of the environment almost always encode the information so that an observer must capture a majority of the environment to deduce the system’s state. Conversely, in the states produced by a typical decoherence process, information about a particular observable of the system is stored redundantly. This selective proliferation of “the fittest information” (known as Quantum Darwinism) plays a key role in choosing the preferred, effectively classical observables of macroscopic systems. The developing appreciation that the environment functions not just as a garbage dump, but as a communication channel, is extending our understanding of the environment’s role in the quantum-classical transition beyond the traditional paradigm of decoherence.

This article deals with the author’s experiences in studying cochlear implantation over a period of some years. While no overt controversy surrounded the device or the practices associated with it in the Netherlands when this work started, studying its introduction became complex. Following others, the research strategy that was evolved might be termed one of mediation and intervention. It entailed treating the views and aspirations of research subjects, clinical and lay, with equal regard. It entailed promotion of dialogue. For reasons (...) that are discussed in the article, the attempt was made to translate this dialogue to the political level. The challenge confronting the author was simultaneously methodological and political. (shrink)

Development of the cochlear implant, discussed in this article, depended vitally on deaf people being persuaded to undergo implantation. Media "reconstruction" of the device as the "bionic ear" was typically encouraged by implant pioneers. Unexpectedly, however, a "counter-rhetoric" based on a very different understanding of deafness emerged. With it, deaf people are slowly succeeding in gaining influence over the further deployment of the technology. The analysis suggests modifications to existing theoretical models of technological change in medicine.

This paper proposes a learning-efficiency explanation of modular structure in language. An optimal grammar arises as the solution to the problem of learning a language from a minimal number of observations of instances of the use of the language. Agents face symmetry constraints that limit their ability to make a priori distinctions among symbols used in the language and among objects (interpreted as facts, events, speaker’s intentions) that are to be represented by messages in the language. It is shown that (...) if it is commonly known that the object space is modular and messages are strings, then modularity of the language is sufficient and (essentially) necessary for learning efficiency.

We introduce a discrete probabilistic model of motion in special and general relativity that is shown to be compatible with the standard model in the statistical limit.

Using the lenses of both biblical and process theology, this essay explores the ways in which sacrament and church are inextricably bound with one another. By paying special attention to the seriousness with which Whiteheadian thought takes events in space and time, the essay develops a sacramentally focused ecclesiology that is radically embodied in the realm of occasions.

This volume of the Sociology of the Sciences Yearbooks stems from our experience that collaborations between non-scientists and scientists, often initiated by scientists seeking greater social relevance for science, can be of major importance for cognitive development. It seemed to us that it would be useful to explore the conditions under which such collaborations affect scientific change and the nature of the processes involved. This book therefore focuses on a number of instances in which scientists and non-scientists were jointly involved (...) in the genera tion of scientific results at the "interface" of science and society. Despite the considerable variety of cases reported here, a number of questions are central. Under what conditions do such cooperative processes occur? What perceptions of social relevance and what sorts of col laborations with non-scientific groups are involved? How is this collaboration achieved, and through what forums? How can insights into its conditions and mechanisms stabilize such cooperations over a longer period of time? If they are stabilized, do they really affect science, or do they mainly function to shield the rest of the science system against external influences? These questions are pertinent both to intellectual problems in the sociology of science and to the practical concerns of modern science policies. The significance of relations between knowledge producers and knowledge consumers and interest in how these relations affect science and society have changed considerably in recent decades. (shrink)

The primary resource for quantum computation is Hilbert-space dimension. Whereas Hilbert space itself is an abstract construction, the number of dimensions available to a system is a physical quantity that requires physical resources. Avoiding a demand for an exponential amount of these resources places a fundamental constraint on the systems that are suitable for scalable quantum computation. To be scalable, the effective number of degrees of freedom in the computer must grow nearly linearly with the number of qubits in an (...) equivalent qubit-based quantum computer. (shrink)

Regulation of the cytoplasmic stability of mRNAs has recetly been identified as a major control mechanism which governs mRNA levels in a variety of eukaryotic systems. In this review we discuss what is known about several experimental systems that exhibit regulated mRNA stability, describe the mechanisms that cells may use to achieve control of mRNA degradation, and suggest areas of future investigation likely to provide new insights into this process.

The literature acknowledges a distinction between immoral, amoral and moral management. This paper makes a case for the employee (at any level) as a moral agent, even though the paper begins by highlighting a body of evidence which suggests that individual moral agency is sacrificed at work and is compromised in deference to other pressures. This leads to a discussion about the notion of discretion and an examination of a separate, contrary body of literature which indicates that some individuals in (...) corporations may use their discretion to behave in a socially entrepreneurial manner. My underlying assumption is that CSR isn’t solely driven by economics and that it may also be championed as a result of a personal morality, inspired by employees’ own socially oriented personal values. A conceptual framework is put forward and it is suggested that individuals may be categorized as Active or Frustrated Corporate Social Entrepreneurs; Conformists or Apathetics, distinguished by their individualistic or collectivist personal values. In a discussion of the nature of values, this paper highlights how values may act as drivers of our behavior and pays particular attention to the values of the entrepreneur, thereby linking the existing debate on moral agency with the field of corporate social responsibility.

Ethical concepts are, or purport to be, normative. They make claims on us: they command, oblige, recommend, or guide. Or at least when we invoke them, we make claims on one another; but where does their authority over us - or ours over one another - come from? Christine Korsgaard identifies four accounts of the source of normativity that have been advocated by modern moral philosophers: voluntarism, realism, reflective endorsement, and the appeal to autonomy. She traces their history, showing (...) how each developed in response to the prior one and comparing their early versions with those on the contemporary philosophical scene. Kant's theory that normativity springs from our own autonomy emerges as a synthesis of the other three, and Korsgaard concludes with her own version of the Kantian account. Her discussion is followed by commentary from G. A. Cohen, Raymond Geuss, Thomas Nagel, and Bernard Williams, and a reply by Korsgaard. (shrink)
