Systematic Reviews Of Animal Experiments Demonstrate Poor Human Clinical And Toxicological Utility, Andrew Knight

Experimentation Collection

The assumption that animal models are reasonably predictive of human outcomes provides the basis for their widespread use in toxicity testing and in biomedical research aimed at developing cures for human diseases. To investigate the validity of this assumption, the comprehensive Scopus biomedical bibliographic databases were searched for published systematic reviews of the human clinical or toxicological utility of animal experiments. In 20 reviews in which clinical utility was examined, the authors concluded that animal models were either significantly useful in contributing to the development of clinical interventions, or were substantially consistent with clinical outcomes, in only two cases, one …

Privacy In Location Aware Computing Environments, Denise Anthony, Tristan Henderson, David Kotz

Dartmouth Scholarship

As location-aware and pervasive computing technologies become more prevalent, privacy concerns are becoming increasingly more important. User preferences about location privacy may depend on place, not only in terms of their physical location but also in terms of their social context: how they define where they are, what they are doing, and whom they are with at the time. Using the experience sampling method, the authors explored the privacy preferences of 25 users during one week. They found that participants were more willing to share location information when at home or alone than when at other locations or with friends. …

Towards Tractable Local Closed World Reasoning For The Semantic Web, Matthias Knorr, Jose Julio Alferes, Pascal Hitzler

Computer Science and Engineering Faculty Publications

Recently, the logics of minimal knowledge and negation as failure MKNF [12] was used to introduce hybrid MKNF knowledge bases [14], a powerful formalism for combining open and closed world reasoning for the Semantic Web. We present an extension based on a new three-valued framework including an alternating fixpoint, the well-founded MKNF model. This approach, the well-founded MKNF semantics, derives its name from the very close relation to the corresponding semantics known from logic programming. We show that the well-founded MKNF model is the least model among all (three-valued) MKNF models, thus soundly approximating also the two-valued MKNF models from …

Role Of Group A Streptococcus Htra In The Maturation Of Speb Protease, J. N. Cole, J. A. Aquilina, P. G. Hains, A. Henningham, K. S. Sriprakash, M. G. Caparon, V. Nizet, M. Kotb, S. J. Cordwell, S. P. Djordjevic, Mark J. Walker

Faculty of Science - Papers (Archive)

The serine protease HtrA (DegP) of the human pathogen Streptococcus pyogenes (group A Streptococcus; GAS) is localized to the ExPortal secretory microdomain and is reportedly essential for the maturation of cysteine protease SpeB. Here we utilize HSC5 (M5 serotype) and the in-frame isogenic mutant HSC5ΔhtrA to determine whether HtrA contributes to the maturation of other GAS virulence determinants. Mutanolysin cell wall extracts and secreted proteins were arrayed by 2-DE and identified by MALDI-TOF PMF analysis. HSC5ΔhtrA had elevated levels of cell wall-associated M protein, whilst the supernatant had higher concentrations of M protein fragments and a reduced amount of mature …

Changing Cultures Of Water In Eastern Australian Backyard Gardens, Lesley M. Head, Pat Muir

Faculty of Science - Papers (Archive)

Research into diverse cultural understandings of water provides important contributions to the pressing global issue of sustainable supply, particularly when combined with analysis of relationships between everyday household practice and larger sociotechnical networks of storage and distribution. Here we analyse semi-structured interviews with 298 people about their 241 backyards in the Australian east coast cities of Sydney and Wollongong, undertaken during the 2002-03 drought. Water emerged as an important issue in both consciousness and practice. In contrast to a number of other environmental issues which stimulate more polarised responses, a commitment to reducing water consumption was shared across the study …

Video On The Semantic Sensor Web, Cory Andrew Henson, Amit P. Sheth, Prateek Jain, Josh Pschorr, Terry Rapoch

Kno.e.sis Publications

Millions of sensors around the globe currently collect avalanches of data about our world. The rapid development and deployment of sensor technology is intensifying the existing problem of too much data and not enough knowledge. With a view to alleviating this glut, we propose that sensor data, especially video sensor data, can be annotated with semantic metadata to provide contextual information about videos on the Web. In particular, we present an approach to annotating video sensor data with spatial, temporal, and thematic semantic metadata. This technique builds on current standardization efforts within the W3C and Open Geospatial Consortium (OGC) and …

Commuting Analysis In A Small Metropolitan Area - A Case Study Of Bowling Green/Warren County, Kentucky, Caitlin Hagar

Masters Theses & Specialist Projects

In previous studies of urban commutes, little attention has been paid to commute patterns in smaller urban areas. In this study, the concept of "excess commute" (EC) is applied to the Bowling Green-Warren County Metropolitan Statistical Area (BGWCMSA) in Kentucky. EC quantifies the portion of commute distance explained by the overall spatial separation of jobs and households. Results in this thesis research show that approximately 65% of commute distance by persons driving alone in the study area can be explained by the physical locations of homes relative to job sites as well as the existing roadway network, leaving an EC …

A General Boosting Method And Its Application To Learning Ranking Functions For Web Search, Zhaohui Zheng, Hongyuan Zha, Tong Zhang, Olivier Chapelle, Keke Chen, Gordon Sun

Kno.e.sis Publications

We present a general boosting method extending functional gradient boosting to optimize complex loss functions that are encountered in many machine learning problems. Our approach is based on optimization of quadratic upper bounds of the loss functions which allows us to present a rigorous convergence analysis of the algorithm. More importantly, this general framework enables us to use a standard regression base learner such as decision trees for fitting any loss function. We illustrate an application of the proposed method in learning ranking functions for Web search by combining both preference data and labeled data for training. We present experimental …

An Empirical Analysis Of Mobile Voice Service And Sms: A Structural Model, Youngsoo Kim, William B. Vogt, Ramayya Krishnan, Rahul Telang

Research Collection School Of Computing and Information Systems

In addition to the wireless telephony boom, a similar exponential increasing trend in wireless data service - short message service (SMS) - is visible as technology advances. We develop a structural model to understand how mobile users behave, especially how they consume voice, and services. Specifically, we measure the own- and the cross-price elasticities of these services. The cross-price elasticity is of significant importance because marketing activities are critically influenced by whether the goods are substitutes or complements. The research context poses significant econometric challenges due to three-part tariff, sequential discrete plan choice and continuous quantity choices. Using detailed individual …

Diagnosis Of The July 6, 2002 Ogallala, Nebraska Flash Flood, David B. Radell, Mark R. Anderson, John W. Stoppkotte, James R. Mccormick

Department of Earth and Atmospheric Sciences: Faculty Publications

During the early morning hours of 6 July 2002, a mesoscale convective system (MCS) traversed southwestern Nebraska and produced more than 40 cm of precipitation, resulting in a flash flood that closed Interstate 80 and caused one fatality near Ogallala, Nebraska. Regional climatology yields that this flash flood ranked first in precipitation amount for a 24 hour period over the past one hundred years. Synoptic and mesoscale features similar to other flash flooding events and conducive to extremely heavy precipitation were in place over the Central Plains, including a weak upper level ridge, high precipitable water values (180% of normal), …

[Accepted Article Manuscript Version (Postprint)] The Social Implications Of Enjoyment Of Different Types Of Music, Movies, And Television Programming, Alice Hall

Communication and Media Faculty Works

This study investigated how information about an individual’s enjoyment of various genres of music, film, and TV programming could influence an observer’s expectations of that individual. An online survey of young adults found that the influence of information about another person’s genre preferences varied across genres. Enjoyment of some genres, including jazz music, film comedies, and television comedies, tended to raise expectations of the individual, whereas enjoyment of others, including heavy metal music, anime films, and television soap operas, tended to lower them. The implications of the findings are discussed in relation to uses and gratifications perspectives as well as …

Effects Of A Switchgrass Buffer Strip On Soil Microorganisms Near A Field Applied With Endosulfan, Cristina Clark-Cuadrado

FIU Electronic Theses and Dissertations

A field study to determine the effects of a switchgrass buffer strip (SBS) on soil microorganisms near a field applied with endosulfan was carried out. Soil samples were taken from a SBS and bare soil area downslope from a field applied with endosulfan at different distances, days, and two seasons (wet and dry). Soil samples were analyzed for endosulfan, soil fungi, and bacteria. Analysis of endosulfan concentrations was done by reversed-phase liquid chromatography. No endosulfan runoff was detected by this method. Analysis of soil fungi and bacteria was done by fungal and bacterial enumeration by plate count method on rose …

The Librarian As Hacker, Getting More From Google, R Philip Reynolds

Librarian and Staff Publications

This paper will cover four areas. First it will discuss the research habits of search engine users and some of the problems with these habits. Then it will discuss librarians' use of search engines. Here we encounter the real question: Do we do much better? Can we use a search engines to their full potential? When needed, can we hack an engine to make it perform beyond its intended function? Can we use a clever workaround to solve a problem? Or are we on a level playing field with our patrons once we get outside traditional database searching? Google currently …

Biomass And Biofuels In Maine: Estimating Supplies For Expanding The Forest Products Industry, Jonathan Rubin, Kate Dickerson, Jacob Kavkewitz

Energy & the Environment

This paper estimates the renewable energy potential of Maine’s forest resources, and how much energy these resources could potentially provide the state. Using the most recent state-specific data available, and a methodology similar to the Billion Tons Report, we find that ethanol production from Maine’s forest residues could potentially provide 18% of Maine’s transportation (gasoline) fuels with a fermentation wood to ethanol process. Making Fischer-Tropsch diesel (F-T diesel) using forest residues can replace 39% of Maine’s petro-diesel consumption. Actual levels of biofuels that can be produced will depend on conversion factors and forestry residue removals that are subject to uncertainty.

Semantic Convergence Of Wikipedia Articles, Christopher J. Thomas, Amit P. Sheth

Kno.e.sis Publications

Social networking, distributed problem solving and human computation have gained high visibility. Wikipedia is a well established service that incorporates aspects of these three fields of research. For this reason it is a good object of study for determining quality of solutions in a social setting that is open, completely distributed, bottom up and not peer reviewed by certified experts. In particular, this paper aims at identifying semantic convergence of Wikipedia articles; the notion that the content of an article stays stable regardless of continuing edits. This could lead to an automatic recommendation of good article tags but also add …

Supporting Complex Thematic, Spatial And Temporal Queries Over Semantic Web Data, Matthew Perry, Amit P. Sheth, Farshad Hakimpour, Prateek Jain

Kno.e.sis Publications

Spatial and temporal data are critical components in many applications. This is especially true in analytical domains such as national security and criminal investigation. Often, the analytical process requires uncovering and analyzing complex thematic relationships between disparate people, places and events. Fundamentally new query operators based on the graph structure of Semantic Web data models, such as semantic associations, are proving useful for this purpose. However, these analysis mechanisms are primarily intended for thematic relationships. In this paper, we describe a framework built around the RDF metadata model for analysis of thematic, spatial and temporal relationships between named entities. We …

Conjunctive Queries For A Tractable Fragment Of Owl 1.1, Markus Krotzsch, Sebastian Rudolph, Pascal Hitzler

Computer Science and Engineering Faculty Publications

Despite the success of the Web Ontology Language OWL, the development of expressive means for querying OWL knowledge bases is still an open issue. In this paper, we investigate how a very natural and desirable form of queries-namely conjunctive ones-can be used in conjunction with OWL such that one of the major design criteria of the latter-namely decidability-can be retained. More precisely, we show that querying the tractable fragment EL++ of OWL 1.1 is decidable. We also provide a complexity analysis and show that querying unrestricted EL++ is undecidable.
