Penn Arts & Sciences

The University of Pennsylvania School of Arts and Sciences forms the foundation of the scholarly excellence that has established Penn as one of the world's leading research universities. We teach students across all 12 Penn schools, and our academic departments span the reach from anthropology and biology to sociology and South Asian studies.

Members of the Penn Arts & Sciences faculty are leaders in creating new knowledge in their disciplines and are engaged in nearly every area of interdisciplinary innovation. They are regularly recognized with academia's highest honors, including membership in prestigious societies like the National Academy of Sciences, the American Association for the Advancement of Science, the American Academy of Arts and Sciences, and the American Philosophical Society, as well as significant prizes such as MacArthur and Guggenheim Fellowships.

The educational experience offered by Penn Arts & Sciences is likewise recognized for its excellence. The School's three educational divisions fulfill different missions, united by a broader commitment to providing our students with an unrivaled education in the liberal arts. The College of Arts and Sciences is the academic home of the majority of Penn undergraduates and provides 60 percent of the courses taken by students in Penn's undergraduate professional schools. The Graduate Division offers doctoral training to over 1,300 candidates in more than 30 graduate programs. And the College of Liberal and Professional Studies provides a range of educational opportunities for lifelong learners and working professionals.

    Religion and Diplomacy
    (1995-11-16) Runcie, Robert A. K.
    Archbishop Runcie's presentation represents well his interest in and experience of the complex intersection between religion and world events. Both his consideration of the difficult history of the Christian Church, and his call to greater understanding of other religions reflect his long work with and commitment to these issues. His refusal to simplify the problems tied to religion is characteristic both of his efforts to find real solutions to world problems and his intellectual rigor.

    Using Syntactic Information in Document Filtering: A Comparative Study of Part-of-Speech Tagging and Supertagging
    (1996-12-01) Chandrasekar, R.; Srinivas, B.
    Any coherent text contains significant latent information, such as syntactic structure and patterns of language use. This information can be exploited to overcome the inadequacies of keyword-based retrieval and make information retrieval more efficient. In this paper, we demonstrate quantitatively how syntactic information is useful in filtering out irrelevant documents. We also compare two different syntactic labelings-- simple Part-of-Speech (POS) labeling and Supertag labeling-- and show how the richer (more fine-grained) representation of supertags leads to more efficient and effective document filtering. We have implemented a system which exploits syntactic information in a flexible manner to filter documents. The system has been tested on a large collection of news sentences, and achieves an F-score of 89 for filtering out irrelevant sentences. Its performance and modularity makes it a promising postprocessing addition to any Information Retrieval system.

    Bringing in the Family: Kinship Support and Contraceptive Behavior
    (1981) Furstenberg, Frank F; Herceg-Baron, Roberta; Jemail, Jay
    Though social programs are usually based on a presumption of empirical knowledge, it is no secret that research typically follows, rather than precedes efforts at social intervention. More often than not, social scientists are called in to assess the impact of an existing programmatic initiative, and are asked to render a judgment about the wisdom of a particular course of action after the fact. Only rarely do they take an active part in planning the experiments that they evaluate.

    Medieval and Modern Jewish History
    (1995) Ruderman, David B
    There has been a virtual explosion of scholarly writing on Jewish history in the medieval and modern periods during the last thirty years. One rough measure of this development is to compare the present entries on Jewish history in this Guide with the previous edition published in 1961. Of the hundred and twenty items on Jewish history listed in the earlier Guide, less than half actually pertain to the medieval and modern periods. This compares with some 325 items allotted to this section of the present Guide dealing exclusively with postancient Jewish history. But the sheer number of cited works is only the beginning of the story. Among the entries in the 1961 edition, the number of individual authors is relatively small; Salo W. Baron is listed several times, as are Cecil Roth, Jacob Marcus, and Guido Kisch. This obviously reflects the relatively small number of professional historians in the field as of 1961 and an even smaller number holding full-time positions in North American universities.

    Accuracy of Diffusing-Wave Spectroscopy Theories
    (1995-04-01) Durian, Douglas J
    Random walk computer simulations are reported for the electric field autocorrelation of photons transmitted through multiple-scattering slabs. The results are used as a benchmark for judging the accuracy of competing theories of diffusing-wave spectroscopy (DWS), and also for distinguishing between errors introduced from the approximation of diffusive photon transport and from the continuum approximation that the total square wave-vector transfer of a transmitted photon is proportional to its path length in the material. An important conclusion is that these errors partially cancel, giving accuracies on the order of a few percent for typical experimental situations. Detailed comparisons are made as a function of optical thickness, boundary reflectivity, as well as scattering anisotropy; guidelines are generated for optimizing the analysis of actual DWS data in terms of the dynamics of individual scattering sites.
