It provides holistic situational awareness from one interface and enables organizational actors to engage in well-coordinated ways for desired tasks during emergency response.

Productivity Growth And Efficiency Changes In Publicly Managed U.S. Comprehensive Universities: Data Envelopment Analysis And Malmquist Decompositions, G. Thomas Sav

Economics Faculty Publications

This paper uses data envelopment analysis and Malmquist index decompositions in estimating productivity and efficiency changes of comprehensive degree granting, publicly owned U.S. universities. Panel data for 247 universities is employed for the academic years 2005-09. Results indicate that universities incurred productivity regress on the order of 4% per annum. The regress was due to declines in technological change that overpowered the efficiency gains achieved by universities. The latter derived from both university management and scale efficiency improvements. The dynamics of annual changes suggest that the financial crisis worsened productivity regress but created positive efficiency changes. It will, however, be …

Bayesian Approaches To Assessing Architecture And Stopping Rule, Joseph W. Houpt, A. Heathcote, A. Eidels, J. T. Townsend

Joseph W. Houpt

Much of scientific psychology and cognitive science can be viewed as a search to understand the mechanisms and dynamics of perception, thought and action. Two processing attributes of particular interest to psychologists are the architecture, or temporal relationships between sub-processes of the system, and the stopping rule, which dictates how many of the sub-processes must be completed for the system to finish. The Survivor Interaction Contrast (SIC) is a powerful tool for assessing the architecture and stopping rule of a mental process model. Thus far, statistical analysis of the SIC has been limited to null-hypothesis- significance tests. In this talk …

The Latent Maximum Entropy Principle, Shaojun Wang, Dale Schuurmans, Yunxin Zhao

Kno.e.sis Publications

We present an extension to Jaynes’ maximum entropy principle that incorporates latent variables. The principle of latent maximum entropy we propose is different from both Jaynes’ maximum entropy principle and maximum likelihood estimation, but can yield better estimates in the presence of hidden variables and limited training data. We first show that solving for a latent maximum entropy model poses a hard nonlinear constrained optimization problem in general. However, we then show that feasible solutions to this problem can be obtained efficiently for the special case of log-linear models---which forms the basis for an efficient approximation to the latent maximum …

Exploring The Impact Of Knowledge And Social Environment On Influenza Prevention And Transmission In Midwestern United States High School Students, William L. Romine, Tanvi Banerjee, William S. Barrow, William R. Folk

Kno.e.sis Publications

We used data from a convenience sample of 410 Midwestern United States students from six secondary schools to develop parsimonious models for explaining and predicting precautions and illness related to influenza. Scores for knowledge and perceptions were obtained using two-parameter Item Response Theory (IRT) models. Relationships between outcome variables and predictors were verified using Pearson and Spearman correlations, and nested [student within school] fixed effects multinomial logistic regression models were specified from these using Akaike’s Information Criterion (AIC). Neural network models were then formulated as classifiers using 10-fold cross validation to predict precautions and illness. Perceived barriers against taking precautions …

The present research aims to detect coordinated citizen response within social media traffic to assist emergency response. We use domain-independent linguistic properties as the first step in narrowing the candidate set of messages for domain-dependent and computationally intensive analysis.

Spillover Effects Of Crimes In Neighboring States Of Mexico, Mingming Pan, Benjamin Widner, Carl E. Enomoto

Economics Faculty Publications

The recent surge in crime and drug-related violence in Mexico has had a profound effect on the Mexican economy. Thousands of businesses have closed in Ciudad Juarez, a city that borders the U.S., due to the violence that has erupted between drug cartels. It has been estimated by Rios (2007) that $4.3 billion of losses occur yearly to Mexico, due to illegal drug activity in the country. Using a spatial model, this paper analyzes the determinants of crime in Mexican states. It was found that high levels of total crime and drug-related violence in neighboring states of Mexico have spillover …

Trailblazers: Moving The Library Upstream In The Digital Distribution Process, Sue Polanka

University Libraries' Staff Publications

On Dec. 20, 2010, Jamie LaRue, director of Douglas County Libraries (DCL), asked his associate director of Information technology, Monique Sendze, "Suppose a patron walked in and wanted to donate an ebook to our library. Could they?" Sendze responded, "No, I don't think so." "So, what do we have to do to be able to accept a book?" wondered LaRue. Sendze said she would find out.

It took 18 months and $100,000, but they found the answer together-locally hosting ebook content. LaRue, Sendze, and the DCL staff set out on a mission. A mission to own, not lease, electronic books. …

Stochastic Cost Inefficiency Estimates And Rankings Of Public And Private Research And Doctoral Granting Universities, G. Thomas Sav

Economics Faculty Publications

Stochastic frontier cost and inefficiency estimates are provided for research and doctoral granting universities in the U.S. Separate sector estimates are produced for public and private non-profit universities. Panel data spanning four academic years, 2005-2009, is used to estimate underlying cost structures. Inefficiency is modeled as depending on institutionally specific environmental factors. Results indicate that public universities are on average more efficient than their private counterparts. The latter exhibit greater variability and when evaluated at the median inefficiencies there does not appear to be any statistically significant difference. Time varying inefficiency estimates point to public sector efficiency gains but private …

A Web-Based Study Of Self-Treatment Of Opioid Withdrawal Symptoms With Loperamide, Raminta Daniulaityte, Robert G. Carlson, Russel S. Falck, Delroy H. Cameron, Sujan Udayanaga, Lu Chen, Amit P. Sheth

Kno.e.sis Publications

Aims: Many websites provide a medium for individuals to freely share their experiences and knowledge about different drugs. Such user-generated content can be used as a rich data source to study emerging drug use practices and trends. The study aims to examine web-based reports of loperamide use practices among non-medical opioid users. Loperamide, a piperidine derivative, is an opioid agonist approved for the control of diarrhea symptoms. Because of its general inability to cross the blood-brain barrier, it is considered to have no abuse potential and is available without a prescription. Methods: A website that allows free discussion of illicit …

Prediction Of Topic Volume On Twitter, Yiye Ruan, Hemant Purohit, David Fuhry, Srinivasan Parthasarathy, Amit P. Sheth

Kno.e.sis Publications

We discuss an approach for predicting microscopic (individual) and macroscopic (collective) user behavioral patterns with respect to specific trending topics on Twitter. Going beyond previous efforts that have analyzed driving factors in whether and when a user will publish topic-relevant tweets, here we seek to predict the strength of content generation which allows more accurate understanding of Twitter users' behavior and more effective utilization of the online social network for diffusing information. Unlike traditional approaches, we consider multiple dimensions into one regression-based prediction framework covering network structure, user interaction, content characteristics and past activity. Experimental results on three large Twitter …

Integrating Owl And Rules: A Syntax Proposal For Nominal Schemas, David Carral Martinez, Adila Krisnadhi, Pascal Hitzler

Computer Science and Engineering Faculty Publications

This paper proposes an addition to OWL 2 syntax to incorporate nominal schemas, which is a new description-logic style extension of OWL 2 which was recently proposed, and which makes is possible to express "variable nominal classes" within axioms in an OWL 2 ontology. Nominal schemas make it possible to express DL-safe rules of arbitrary arity within the extended OWL paradigm, hence covering the well-known DL-safe SWRL language. To express this feature, we extend OWL 2 syntax to include necessary and minimal modifications to both Functional and Manchester syntax grammars and mappings from these two syntaxes to Turtle/RDF. We also …

We anticipate that this document will evolve as EarthCube progresses. Indeed, all EarthCube parties are asked to provide topics of importance that should be treated in …

Trust Networks, Krishnaprasad Thirunarayan, Pramod Anantharam, Cory Andrew Henson, Amit P. Sheth

Kno.e.sis Publications

Trust relationships occur naturally in many diverse contexts such as collaborative systems, e-commerce, interpersonal interactions, social networks, semantic sensor web, etc. As collaborating agents providing content and services become increasingly removed from the agents that consume them, the issue of robust trust inference and update become critical. There is a need to find online substitutes for traditional (direct or face-to-face) cues to derive measures of trust, and create efficient and secure system for managing trust, to support decision-making. Unfortunately, there is neither a universal notion of trust that is applicable to all domains nor a clear explication of its semantics …

2012 Yellow Springs Cost Of Living Report, Center For Urban And Public Affairs, Wright State University

Economic Development

Many issues our community has faced in recent years reflect an underlying concern about our economic circumstances, particularly the cost of living in Yellow Springs, Ohio. The absence of reliable, accurate and objective information has contributed to conjecture and debate among residents. Early in this year, the James A. McKee Association resolved to try to help address this gap by sponsoring a study of the cost of living in the village. The availability of current Census data made this a particularly appropriate time to undertake this study. The hope is that this project will form a foundation for better understanding …

Extending Description Logic Rules, David Carral Martinez, Pascal Hitzler

Computer Science and Engineering Faculty Publications

Description Logics – the logics underpinning the Web Ontology Language OWL – and rules are currently the most prominent paradigms used for modeling knowledge for the Semantic Web. While both of these approaches are based on classical logic, the paradigms also differ significantly, so that naive combinations result in undesirable properties such as undecidability. Recent work has shown that many rules can in fact be expressed in OWL. In this paper we extend this work to include some types of rules previously excluded. We formally define a set of first order logic rules, C-Rules, which can be expressed within OWL …

Ungluing Open Access Ebooks, Sue Polanka

University Libraries' Staff Publications

Buying a print book is relatively easy. With the introduction of library ebooks in 1999, however, a once-straightforward process took on many complexities. Before starting, ask yourself why your library needs to purchase ebooks. Is it to expand a collection or to increase the buying power of a group of libraries? To replace existing print collections, offer new services, or experiment with new business models in the hope of saving money? Whatever the reason, it is imperative to keep your goals in mind.
