Two models for an effective undergraduate research experience in physiology and other natural sciences.

68A realistic research experience is beneficial to undergraduate students, but it is often difficult for liberal arts colleges to offer this opportunity. We describe two approaches for developing and maintaining an interdisciplinary research program at small colleges. An active and continuing involvement of an individual with extensive research experience is an essential element in both. One model was developed by the faculty of Taylor University, Upland, IN and a research scientist who had retired from a major university to join the Taylor faculty as their first Research Professor. The school's Science Research Training Program was initially funded by a modest endowment provided by interested alumni and by extramural grants awarded to the Research Professor and to the institution; the program now enjoys significant funding from diverse sources. Taylor is not located near any large research university and consequently supplies all resources required for the experiments and stipends for students pursuing projects full-time during the summer. The second model was developed by the faculty at Asbury College in Wilmore, KY, working with a scientist having a full-time appointment at the University of Kentucky and a part-time appointment at the college. In this approach, Asbury faculty may place their students for a period of training, often during the summer, in a laboratory of a cooperating host faculty at the University of Kentucky or other institution. The host faculty funds the research and pays a stipend to those students who work full-time during the summer. Relationships established between faculty at the College and at the University of Kentucky have been mutually beneficial. The success of both programs is evidenced by the students' presenting their data at state and national scientific meetings, by their publishing their results in national journals, and by the undergraduate school faculty developing independent research programs.

Reflections on the disciplinary gulf between the natural and social sciences.

The general purpose of this essay is to explore key features of the disciplinary gulf between the natural and social sciences, and, in particular, differences in fundamental assumptions concerning the nature and purpose of knowledge. The essay contrasts the claims of the natural sciences to objectivity and universality with those of the social sciences, especially the qualitative social sciences, to the historical and cultural contingency of knowledge. It examines the ways in which the use of two 'key words' - 'expertise' and 'responsibility'--serves to maintain the disciplinary gulf by reinforcing assumptions concerning the neutrality and technical nature of scientific knowledge and how those concepts marginalize social and ethical dimensions to create a politically influential hierarchy of knowledge claims.

The silence of Socrates.

This paper emphasizes the humanistic and phenomenologic approach to the mind (soul, self) and contrasts it to the "era of the brain" that is so idealized by psychiatry today. It describes the debate between those who expect science to explain everything sooner or later and those who believe there are certain essential aspects of the world, such as the qualia of consciousness, that cannot be reduced to material factors. Plato's dialogue Timaeus is taken as the historically first example of this debate. The connection between it and what has been labeled "neuroism" in contemporary psychiatry is established and the relevance of this debate to the practice of psychoanalysis and dynamic psychiatry is discussed. Finally the wider consequences of the scientific or materialistic approach to the world as forecast already by Nietzsche are indicated.

Liebig, his university professor Karl Wilhelm Gottlob Kastner (1783-1857) and his problematic relation with romantic natural philosophy.

The chemist and physicist K. W. G. Kastner is almost unknown today, even though during his lifetime he was among the most respected of German physical scientists. Only the fact that Justus Liebig studied and did his doctorate with him seems to be of (small enough) interest today. Kastner's life and career are shown to be extremely worth analyzing since, like Liebig himself, he succeeded in making his way from being a pharmacist to becoming a university professor. He published numerous textbooks as well as journals, he had a great number of students and he was a popular lecturer. In striking contrast to this are the negative statements of his student Liebig about Romantic Natural Philosophy and about Kastner himself, despite his being of crucial importance for Liebig's career as a teacher and mentor. These critical statements, for which a variety of explanations are known, markedly prejudiced Kastner's reputation for posterity.

Perceptual knowledge retrieval activates sensory brain regions.

Although knowledge indexes our experiences of the world, the neural basis of this relationship remains to be determined. Previous neuroimaging research, especially involving knowledge biased to visual and functional information, suggests that semantic representations depend on modality-specific brain mechanisms. However, it is unclear whether sensory cortical regions, in general, support retrieval of perceptual knowledge. Using neuroimaging methods, we show that semantic decisions that index tactile, gustatory, auditory, and visual knowledge specifically activate brain regions associated with encoding these sensory experiences. Retrieval of tactile knowledge was specifically associated with increased activation in somatosensory, motor, and premotor cortical regions. In contrast, decisions involving flavor knowledge increased activation in an orbitofrontal region previously implicated in processing semantic comparisons among edible items. Perceptual knowledge retrieval that references visual and auditory experiences was associated with increased activity in distinct temporal brain regions involved in the respective sensory processing. These results indicate that retrieval of perceptual knowledge relies on brain regions used to mediate sensory experiences with the referenced objects.

[Cathedrals to sciences or temples of knowledge? The museums of natural sciences of Cordoba, Argentina, by the end of the 19th century].

The museums of Botany, Mineralogy and Zoology of the Facultad de Ciencias Físico-Matemáticas were created along with a world wide phenomenon, defined by some authors as the "museum movement," in a time the basics of this movement were being restructured. Thus, this work intends to go over the building stage of the natural history museums in a peripheral domain --- Cordoba by the end of the 19th century --- in order to partially understand this transition process. The strategy is to analyze the collections and find out how and why they were gathered. Two other aspects are also relevant: the human resources and the funds these institutions were granted.

[Trueness of modern natural science (1): the scientific revolution and the problem of philosophy].

How can one characterize modern Europe? This problem is essentially related to the meaning of modern natural science, which was developed during the scientific revolution. Then how did viewpoints change during this revolution? The answer to this question also determined the basic character of modern philosophy. Through the examination of Aristotle's geocentric theory and kinematics, I have come to believe that the defect of Aristotle's was that he concluded that a visible sense image is an actual reflection of the reality as it is. From this point of view, the traditional theory of truth called "correspondence theory" is found to be an insufficient one. Therefore, in this paper I will show that the methodological and philosophical question "How do we see reality among phenomena?" is a very important one. This question is the one Plato struggled with, and also the one which guided Kant. It may be said that this can be seen as a group for a new metaphysics as a basic theory of reality.
