Venetian Glass Beads And The Slave Trade From Liverpool, 1750-1800, Saul Guerrero

BEADS: Journal of the Society of Bead Researchers

The competition within the slave trade during the 18th century forced slave traders to search for an assortment of barter cargo that would attract the preferential attention of the African suppliers of slaves. An enterprising group of Liverpool slave traders that formed William Davenport & Co. rose to the occasion and in three years became the supplier of half of all the glass beads re-exported to Africa from England. An analysis of barter values in Bonny, West Africa, reveals that glass beads were one of the main categories of trade goods of great interest to the African slave traders. The …

Women In The Academy: Reflections On Best Practices For Survival And Success, Nancy Cantor

Chancellor's Collection

As we think about best practices for promoting the lives and careers of women in the academy, we should note that a revolution is underway in American society that shows no sign of reversing itself in the long term. For the first time in history, women are half of all U.S. workers. This is a social transformation that affects every aspect of our lives. And it is certainly affecting the landscape of the academy. Women are the majority. We earn 60 percent of the college degrees awarded each year and half of the PhDs and professional degrees. In the past …

Spatial Isomorphisms Of Algebras Of Truncated Toeplitz Operators, William T. Ross, Stephan Ramon Garcia, Warren R. Wogen

Department of Math & Statistics Faculty Publications

We examine when two maximal abelian algebras in the truncated Toeplitz operators are spatially isomorphic. This builds upon recent work of N. Sedlock, who obtained a complete description of the maximal algebras of truncated Toeplitz operators.

The Norm Of A Truncated Toeplitz Operator, William T. Ross, Stephan Ramon Garcia

Department of Math & Statistics Faculty Publications

We prove several lower bounds for the norm of a truncated Toeplitz operator and obtain a curious relationship between the H² and H^∞ norms of functions in model spaces.

Pathogenic And Opportunistic Microorganisms In Caves, Valme Jurado, Leonila Laiz, Veronica Rodriguez-Nava, Patrick Boiron, Bernardo Hermosin, Sergio Sanchez-Moral, Cesareo Saiz-Jimenez

International Journal of Speleology

With today’s leisure tourism, the frequency of visits to many caves makes it necessary to know about possible potentially pathogenic microorganisms in caves, determine their reservoirs, and inform the public about the consequences of such visits. Our data reveal that caves could be a potential danger to visitors because of the presence of opportunistic microorganisms, whose existence and possible development in humans is currently unknown.

Digraphs With Isomorphic Underlying And Domination Graphs: 4-Cycles And Pairs Of Paths, Kim A. S. Factor, Larry J. Langley

Mathematics, Statistics and Computer Science Faculty Research and Publications

A domination graph of a digraph D, dom(D), is created using the vertex set of D, V(D). There is an edge uv in dom(D) whenever (u, z) or (v, z) is in the arc set of D, A(D), for every other vertex z ε V(D). For only some digraphs D has the structure of dom(D) been characterized. Examples of this are tournaments and regular digraphs. The authors have characterizations for the structure of digraphs D for …

But it comes with a high price, interruption, anywhere anytime. These unwanted interruptions cause loss of productivity and also mostly not beneficial to the immediate task at hand, and moving them few minutes into the future can increase productivity. Considering receiver’s unavailability, it is possible to manage cell phone disruptions using advanced features like sensing capability, ubiquitous computing and context aware systems. This paper proposes the architecture of a system named Mobile Intelligent …

Local Out-Tournaments With Upset Tournament Strong Components I: Full And Equal {0,1}-Matrix Ranks, Kim A. S. Factor, Rebecca M. Kohler, Jason M. Derby

Mathematics, Statistics and Computer Science Faculty Research and Publications

A digraph D is a local out-tournament if the outset of every vertex is a tournament. Here, we use local out-tournaments, whose strong components are upset tournaments, to explore the corresponding ranks of the adjacency matrices. Of specific interest is the out-tournament whose adjacency matrix has boolean, nonnegative integer, term, and real rank all equal to the number of vertices, n. Corresponding results for biclique covers and partitions of the digraph are provided.

Digraphs With Isomorphic Underlying And Domination Graphs: Pairs Of Paths, Kim A. S. Factor, Larry J. Langley

Mathematics, Statistics and Computer Science Faculty Research and Publications

A domination graph of a digraph D, dom (D), is created using thc vertex set of D and edge uv ϵ E (dom (D)) whenever (u, z) ϵ A (D) or (v, z) ϵ A (D) for any other vertex z ϵ A (D). Here, we consider directed graphs whose underlying graphs are isomorphic to their domination graphs. Specifically, digraphs are completely characterized where UG^c (D) is the union of two disjoint paths.

Lower Semimodular Inverse Semigroups, Ii, Peter R. Jones, Kyeong Hee Cheong

Mathematics, Statistics and Computer Science Faculty Research and Publications

The authors’ description of the inverse semigroups S for which the lattice ℒℱ(S) of full inverse subsemigroups is lower semimodular is used to describe those for which (a) the lattice ℒ(S) of all inverse subsemigroups or (b) the lattice �o(S) of convex inverse subsemigroups has that property. In each case, we show that this occurs if and only if the entire lattice is a subdirect product of ℒℱ(S) with ℒ(E _S ), or �o(E _S ), respectively, where E _S is the semilattice of idempotents of …

Dr. Cézanne And The Art Of Re(Peat)Search: Competing Interests And Obligations In Clinical Research, Robyn Bluhm, Jocelyn Downie, Jeff Nisker

Articles, Book Chapters, & Popular Press

Clinician researchers have a number of roles, each of which carries specific obligations. There are times when these obligations may be in competition (up to and including conflict) with each other. Using a narrative case study that describes a group of colleagues discussing their clinical department's participation in an industry-sponsored research protocol, we illustrate a number of the obligations faced by clinician researchers, and discuss how competing interests and obligations can lead to ethical problems. The case study is followed by a discussion of the effect of university–industry relations on competing interests and obligations in both clinical research and the …

The Impact Of China's Antitrust Law And Other Competition Policies On U.S. Companies, Susan Beth Farmer

Faculty Scholarship

This article is based on the author's testimony for part of the hearings on “The Impact of China’s Antitrust Law and Other Competition Policies On U.S. Companies,” held by the House Committee on the Judiciary, Subcommittee on Courts and Competition Policy on July 13, 2010. It describes developments in the enforcement and application of the Chinese Anti-Monopoly Law, interpretation and enforcement during the two years since the AML came into effect, with particular attention to merger review. It comments on the organization and staffing of the enforcement agencies and the publication of numerous procedures, guidelines and regulations, which suggests that …

Not Every Co-Existential Map Is Confluent, Paul Bankston

Mathematics, Statistics and Computer Science Faculty Research and Publications

A continuous surjection between compacta is co-existential if it is the second of two maps whose composition is a standard ultracopower projection. Co-existential maps are always weakly confluent, and are even monotone when the range space is locally connected; so it is a natural question to ask whether they are always confluent. Here we give a negative answer. This is an interesting question, mainly because of the fact that most theorems about confluent maps have parallel versions for co-existential maps---notably, both kinds of maps preserve hereditary indecomposability. Where the known parallels break down is in the question of chainability. It …

Truncated Toeplitz Operators: Spatial Isomorphism, Unitary Equivalence, And Similarity, William T. Ross, Joseph A. Cima, Stephan Ramon Garcia, Warren R. Wogen

Department of Math & Statistics Faculty Publications

A truncated Toeplitz operator Aᵩ : K_Ɵ → K_Ɵ is the compression of a Toeplitz operator Tᵩ : H² → H² to a model space K_Ɵ := H² ⊖ ^ƟH². For Ɵ inner, let T_Ɵ denote the set of all bounded truncated Toeplitz operators on K_Ɵ. Our main result is a necessary and sufficient condition on inner functions Ɵ₁ and Ɵ₂ which guarantees that T_Ɵ1 and T_Ɵ2 are spatially isomorphic. (i.e., UT_Ɵ1 = T_Ɵ2 U for some unitary U : K_{Ɵ1 …}

Rapid Emergence Of Co-Colonization With Community-Acquired And Hospital-Acquired Methicillin-Resistant Staphylococcus Aureus Strains In The Hospital Setting, Joanna R. Wares, Erika M.C. D'Agata, Glenn F. Webb

Department of Math & Statistics Faculty Publications

Background: Community-acquired methicillin-resistant Staphylococcus aureus (CAMRSA), a novel strain of MRSA, has recently emerged and rapidly spread in the community. Invasion into the hospital setting with replacement of the hospital-acquired MRSA (HA-MRSA) has also been documented. Co-colonization with both CA-MRSA and HA-MRSA would have important clinical implications given differences in antimicrobial susceptibility profiles and the potential for exchange of genetic information.

Methods: A deterministic mathematical model was developed to characterize the transmission dynamics of HA-MRSA and CA-MRSA in the hospital setting and to quantify the emergence of co-colonization with both strains Results: The model analysis shows that the …

Automation Process For Morphometric Analysis Of Volumetric Ct Data From Pulmonary Vasculature In Rats, Rahul Shingrani, Gary S. Krenz, Robert Molthen

Mathematics, Statistics and Computer Science Faculty Research and Publications

With advances in medical imaging scanners, it has become commonplace to generate large multidimensional datasets. These datasets require tools for a rapid, thorough analysis. To address this need, we have developed an automated algorithm for morphometric analysis incorporating A Visualization Workshop computational and image processing libraries for three-dimensional segmentation, vascular tree generation and structural hierarchical ordering with a two-stage numeric optimization procedure for estimating vessel diameters. We combine this new technique with our mathematical models of pulmonary vascular morphology to quantify structural and functional attributes of lung arterial trees. Our physiological studies require repeated measurements of vascular structure to determine …

Improving Accuracy Of Large-Scale Prediction Of Forest Disease Incidence Through Bayesian Data Reconciliation, Ephraim M. Hanks

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Increasing the accuracy of predictions made from ecological data typically involves replacing or replicating the data, but the cost of updating large-scale data sets can be prohibitive. Focusing resources on a small sample of locations from a large, less accurate data set can result in more reliable observations, though on a smaller scale. We present an approach for increasing the accuracy of predictions made from a large-scale eco logical data set through reconciliation with a small, highly accurate data set within a Bayesian hierarchical modeling framework. This approach is illustrated through a study of incidence of eastern spruce dwarf mistletoe …

Acculturating Forensic Science: What Is ‘Scientific Culture’, And How Can Forensic Science Adopt It?, Simon A. Cole

Fordham Urban Law Journal

Part I, describes how the NAS Report characterizes “scientific culture.” I suggest that the described attributes of scientific culture are vague and unspecific, and that more thought is necessary to elucidate how they might map onto forensic science. In Part II, I suggest that the NAS Report’s characterization of “scientific culture” is based on popular accounts of science and “the scientific method.” I suggest that these accounts are incomplete, generally considered obsolete, and not particularly helpful in pointing a way toward reform of forensic science. In Part III, I posit a conception of science as work rather than method. In …

Social Class Experiences Of Working-Class Students: Transitioning Out Of College, Carey Treager Huber

All-Inclusive List of Electronic Theses and Dissertations

Issues surrounding social class are often overlooked and rarely discussed in higher education; however, they affect students and institutions in critical ways. Although research has demonstrated that social class is a predictor of access to college, retention, academic performance, overall undergraduate and graduate experience, and college completion, little is known about the effect of social class on students‟ transition out of college and into the workplace. This transition is critical to explore because research suggests that the way in which students approach their first years of work have an impact on future job success and satisfaction. A phenomenological method of …
