Bohemian Faceted-Spheroidal Mold-Pressed Glass Bead Attributes: Hypothesized Terminus Post Quem Dates For The 19th Century, Lester A. Ross

BEADS: Journal of the Society of Bead Researchers

Faceted-spheroidal mold-pressed beads have been manufactured in Bohemia since the 18th century. Evolution of manufacturing technology has resulted in the creation of bead attributes that can readily be observed on beads from archaeological contexts. Many North American archaeological sites contain examples of this bead type; but few reports have identified the attributes, much less recognized these beads as mold-pressed. Enough evidence now exists to suggest that some of these attributes have temporal significance for dating archaeological bead assemblages. Terminus post quem dates for faceted-spheroidal mold-pressed bead attributes are hypothesized, and a strategy for future research is suggested so that a …

Early Upper Paleolithic Ornaments From Üçaǧizli Cave, Turkey, Mary C. Stiner, Steven L. Kuhn

BEADS: Journal of the Society of Bead Researchers

Beads and similar ornaments appear early in the archaeological record associated with modern humans (Homo sapiens), first in Africa and somewhat later in Eurasia. They are thought to be among the first indicators of human use of symbols. This paper discusses criteria used to distinguish early mollusk-shell beads from other kinds of shells in archaeological deposits, focusing on evidence from the site of Üçaǧizli Cave in Turkey. Upper Paleolithic beadmakers at this and other sites clearly preferred certain forms of shell for ornamental purposes, although the reasons for that selectivity remain obscure.

Birds, Beasts, And Botanicals: Organic Beads And Pendants From The Amazon Basin, Deborah G. Harding

BEADS: Journal of the Society of Bead Researchers

The people of the Amazon Basin have an incredible array of organic materials available to them, which they use to make beads and pendants. The Carnegie Museum of Natural History in Pittsburgh, Pennsylvania, has extensive recent collections from the Amazon Basin, with hundreds of necklaces, belts, aprons, and ear and arm ornaments which contain beads made from organic materials. These collections are used to illustrate a variety of the beads and their materials.

Generalized Metrics And Uniquely Determined Logic Programs, Pascal Hitzler, Anthony K. Seda

Computer Science and Engineering Faculty Publications

The introduction of negation into logic programming brings the benefit of enhanced syntax and expressibility, but creates some semantical problems. Specifically, certain operators which are monotonic in the absence of negation become non-monotonic when it is introduced, with the result that standard approaches to denotational semantics then become inapplicable. In this paper, we show how generalized metric spaces can be used to obtain fixed-point semantics for several classes of programs relative to the supported model semantics, and investigate relationships between the underlying spaces we employ. Our methods allow the analysis of classes of programs which include the acyclic, locally hierarchical, …

Semantic N-Gram Language Modeling With The Latent Maximum Entropy Principle, Shaojun Wang, Dale Schuurmans, Fuchun Peng, Yunxin Zhao

Kno.e.sis Publications

We describe a unified probabilistic framework for statistical language modeling-the latent maximum entropy principle-which can effectively incorporate various aspects of natural language, such as local word interaction, syntactic structure and semantic document information. Unlike previous work on maximum entropy methods for language modeling, which only allow explicit features to be modeled, our framework also allows relationships over hidden features to be captured, resulting in a more expressive language model. We describe efficient algorithms for marginalization, inference and normalization in our extended models. We then present experimental results for our approach on the Wall Street Journal corpus.

Kuhn's Paradigm As A Parable For The Cold War: Incommensurability And Its Discontents From Fuller's Tale Of Harvard To Fleck's Unsung Lvov, Babette Babich

Articles and Chapters in Academic Book Collections

In a journal issue dedicated to a discussion of Steve Fuller's Thomas Kuhn: A Philosophical History for Our Times, I argue that Kuhn’s limited acknowledgment of Fleck’s influence on his The Structure of Scientific Revolutions was due to a foundational incommensurability between the standard conceptual framework for philosophical studies of science and Fleck’s historico-social and praxis-oriented approach to scientific progress. The incommensurability in question constituted an insurmountable tension between the kind of language and thinking manifest in Fleck’s study and the conceptual language evident in Kuhn and characteristic of one might still call the received view’ in philosophy of science. …

Web Service: Been There, Done That?, Steffen Staab, Will Van Der Aalst, V. Richard Benjamins, Amit P. Sheth, John A. Miller, Chistoph Bussler, Alexander Maedche, Dieter Fensel, Dennis Gannon

Kno.e.sis Publications

Web services can be defined as loosely coupled, reusable software components that semantically encapsulate discrete functionality and are distributed and programmatically accessible over standard Internet protocols. Web services have received a lot of hype, the reasons for which are not easily determined. Some of their benefits might even seem to waste away, once we touch on the nitty-gritty details, because Web services per se do not offer a solution to underlying problems. The contributions included in this section delve into some of these issues, including: pitfalls of workflow issues; structuring procedural knowledge into problem-solving methods; discussing how a low initial …

Reducing Automobile Emissions In Southern California: The Dance Of Public Policies And Technological Fixes, Rudi Volti

Pitzer Faculty Publications and Research

For many years I have taught at a small liberal arts college in Southern California. When first-year students arrived at the college in the early 1970s, they settled into the usual things that occupy freshmen. A few weeks would go by, and then they would make a remarkable discovery: tall mountains would appear to the north as autumn weather dissipated the heavy blanket of smog that had obscured them. Today, the air is not perfectly clear in September, but students are aware of the mountains from the day they move into the dormitories. The region's partial victory over smog illustrates …

Growth Strategies And Intellectual Capital Formation In New And Emerging Heis, Ellen Hazelkorn

Books/Book chapters

Higher educational institutions are being asked to contribute more effectively and efficiently to economic growth, innovation and intellectual capital. As they do so, the academy has also come under pressure. The content of academic work, the role of faculty, and the balance between teaching, research and service, have, arguably, been restructured, reconfigured and redefined. For academics within traditional universities, pressures for accountability and social relevance have challenged what many valued as ‘their autonomy’. But, for staff within new and emerging HEIs, those formed or reconstituted circa. 1970, there have been different pressures. Many were hired originally as teachers and now …

Formal Concept Analysis And Resolution On Algebraic Domains - Preliminary Report, Matthias Wendt, Pascal Hitzler

Computer Science and Engineering Faculty Publications

We relate two formerly independent areas: Formal concept analysis and logic of domains. We will establish a correspondence between contextual attribute logic on formal contexts resp. concept lattices and a clausal logic on coherent algebraic cpos. We show how to identify the notion of formal concept in the domain theoretic setting. In particular, we show that a special instance of the resolution rule from the domain logic coincides with the concept closure operator from formal concept analysis. The results shed light on the use of contexts and domains for knowledge representation and reasoning purposes.

Learning Continuous Latent Variable Models With Bregman Divergences, Shaojun Wang, Dale Schuurmans

Kno.e.sis Publications

We present a class of unsupervised statistical learning algorithms that are formulated in terms of minimizing Bregman divergences— a family of generalized entropy measures defined by convex functions. We obtain novel training algorithms that extract hidden latent structure by minimizing a Bregman divergence on training data, subject to a set of non-linear constraints which consider hidden variables. An alternating minimization procedure with nested iterative scaling is proposed to find feasible solutions for the resulting constrained optimization problem. The convergence of this algorithm along with its information geometric properties are characterized.

Still Patently Unconstitutional: A Reply To Professor Nard, Margo A. Bagley

Faculty Articles

In Defense of Geographic Disparity is Professor Craig Nard's response to my article Patently Unconstitutional: The Geographical Limitation on Prior Art in a Small World (Patently Unconstitutional). According to Professor Nard, my article advocates "the elimination of [the] geographic disparity" of 35 U.S.C § 102 in order to "protect developing nations and indigenous peoples from Western countries' patent law regimes." Professor Nard is correct in his assertion that I seek the elimination of the geographical disparity in U.S. patent law; however, he misses the mark as to my reasons. My opposition to the geographical limitation does not derive from …

Introducing The Global Diffusion Of The Internet Series, Peter Wolcott, Seymour E. Goodman

Information Systems and Quantitative Analysis Faculty Publications

Many genes can play a role in multiple biological processes or molecular functions. Identifying multifunctional genes at the genome-wide level and studying their properties can shed light upon the complexity of molecular events that underpin cellular functioning, thereby leading to a better understanding of the functional landscape of the cell. However, to date, genome-wide analysis of multifunctional genes (and the proteins they encode) has been limited. Here we introduce a computational approach that uses known functional annotations to extract genes playing a role in at least two distinct biological processes. We leverage functional genomics data sets for three organisms—H. sapiens, …

Global Diffusion Of The Internet - I: India: Is The Elephant Learning To Dance?, Peter Wolcott, Seymour E. Goodman

Information Systems and Quantitative Analysis Faculty Publications

With his proclamation in 1998 that "IT is India's tomorrow", Prime Minister Vajpayee captured a vision of a 21st century India substantially different from that of the previous century, with its high levels of poverty, bloated bureaucracies, and protectionist policies. He envisioned the new India as a major IT power, fully integrated with the global economy, bringing about substantial domestic and international benefit. The Internet is a key to this vision, both as an enabler of technology-based change, and as an indicator of the vision's fulfillment.

Using an analytic framework developed by the authors and others, this study documents the …

Icts As An Aid To Inclusivity?: Barriers To Benefits For Adult Learners In The Ennis Information Age Town, Anna Greenhalgh

Masters

The subject of this thesis is the potential role of ICTs as a means of addressing social exclusion. ICTs have been recognised for their double-edged promise: while they may open opportunities in work, education and social practices, their benefits may be inaccessible to disadvantaged members of society. This subject is explored by means of a case study of adult learners who have been exposed to a ‘social experiment’ involving technological endowment of an Irish community: the Ennis Information Age Town project. This large-scale private sector initiative, which ran between 1997 and 2002, has the potential to inform future ICT projects …

Mitigating The Negative Effects Of Stress In Space Flight: A Transactional Approach, Haydee Maria Cuevas

Publications

The primary goal of this theoretical paper is to highlight how a transactional approach to investigating stressor effects during space flight can lead to a greater understanding of the complex processes by which humans adapt psychologically and physically to the adverse conditions encountered in this extreme environment.Transactional approaches conceptualize stress as occurring in the nature of the "transaction" (Le., interaction) between the individual and the stimulus environment, emphasizing the role of cognitive appraisal (Le., perceived ability to cope with the situation). Interventions that positively influence this cognitive appraisal process may, therefore, lessen the experience of stress and optimize human performance …

Web Service Technologies And Their Synergy With Simulation, Senthilanand Chandrasekaran, Gregory S. Silver, John A. Miller, Jorge Cardoso, Amit P. Sheth

Kno.e.sis Publications

The World Wide Web has had a huge influence on the computing field in general as well as simulation in particular (e.g., Web-Based Simulation). A new wave of development based upon XML has started. Two of the most interesting aspects of this development are the Semantic Web and Web Services. This paper examines the synergy between Web service technology and simulation. In one direction, Web service processes can be simulated for the purpose of correcting/improving the design. In the other direction, simulation models/components can be built out of Web services. Work on seamlessly using simulation as a part of Web …

On Computing Condensed Frequent Pattern Bases, Jian Pei, Guozhu Dong, Wei Zou, Jiawei Han

Kno.e.sis Publications

Frequent pattern mining has been studied extensively. However, the effectiveness and efficiency of this mining is often limited, since the number of frequent patterns generated is often too large. In many applications it is sufficient to generate and examine only frequent patterns with support frequency in close-enough approximation instead of in full precision. Such a compact but close-enough frequent pattern base is called a condensed frequent patterns-base.

In this paper, we propose and examine several alternatives at the design, representation, and implementation of such condensed frequent pattern-bases. A few algorithms for computing such pattern-bases are proposed. Their effectiveness at pattern …

Semantic Web Services And Processes: Semantic Composition And Quality Of Service, Jorge Cardoso, Chistoph Bussler, Amit P. Sheth, Dieter Fensel

Kno.e.sis Publications

Web Services are increasingly being adapted by Enterprises as the new approach to component-based solutions for enterprise applications. They hold potential to transform Web from a collection of information resources to a distributed computing platform. Many enterprise applications, including those supporting e-commerce take a form of processes, which need to be created from individual Web Services and other software components.

The Internet In India And China, Larry Press, William Foster, Peter Wolcott, William Mchenry

Information Systems and Quantitative Analysis Faculty Publications

This article compares the diffusion of the Internet in China and India. Using a six–dimension framework for characterizing the state of the Internet in a nation, we observe that, while both nations have made significant progress since our last comparison (in 1999), China enjoys a substantial lead over India.

We also examine determinants of Internet diffusion. We find that the Chinese Internet has benefited from economic and trade reform begun in the late 1980s, a strong government commitment to the Internet, complementary human and capital resources, etc. The two nations have very different governments and policies, leading to differing approaches …

How Many Black-Tailed Prairie Dogs Were There? A Dialogue Demonstrates Both The Process Of Science And The Role Of Science In Environmental Issues, Svata M. Louda

Svata M. Louda Publications

In this Dialogue, Dallas Virchow and Scott Hygnstrom challenge the present, widely held view that the numbers of black-tailed prairie dogs have declined significantly in post-settlement times. Using quotes and numbers from historical accounts of the occurrence of the prairie dog by the early explorers and settlers, they build a case that occurrence and abundance of the prairie dog in the shortgrass prairies and midgrass regions to the west of the tallgrass region in the Great Plains cannot be used to estimate the presettlement abundance of the species in tallgrass areas. They argue that the activities of early settlers, including …
