A Visualization Model Used For Determining The Effectiveness Of Information Retrieval In A Scientific Database, Nestor L. Osorio, Samantha Johnson

Library Philosophy and Practice (e-journal)

In this study, we demonstrate that a visualization model can determine the effectiveness of searching a bibliographic database, when three descriptive metadata fields are compared. The Inspec database was searched to create a bibliography of articles about a broad scientific topic, interplanetary travel. We collected metadata from 823 Inspec articles and used the Sci2 Tool to create co-occurrence networks based on subject terms, title keywords, and classification codes from each of the articles. The Watts-Strogatz clustering coefficient model was used to create molecular organization of the networks. This method identified subject domain clusters for each of the three selected metadata …

Virtual Values For Taint And Information Flow Analysis, Prakasam Kannan, Thomas Austin, Mark Stamp, Tim Disney, Cormac Flanagan

Faculty Publications, Computer Science

Security controls such as taint analysis and information flow analysis can be powerful tools to protect against many common attacks. However, incorporating these controls into a language such as JavaScript is challenging. Native implementations require the support of all JavaScript VMs. Code rewriting requires developers to reason about the entire abstract syntax of JavaScript. In this paper, we demonstrate how virtual values may be used to more easily integrate these security controls. Virtual values provide hooks to alter the behavior of primitive operations, allowing programmers to create the desired security controls in a more declarative fashion, facilitating more rapid prototyping. …

A Method For Revealing And Addressing Security Vulnerabilities In Cyber-Physical Systems By Modeling Malicious Agent Interactions With Formal Verification, Dean C. Wardell, Robert F. Mills, Gilbert L. Peterson, Mark E. Oxley

Faculty Publications

Several cyber-attacks on the cyber-physical systems (CPS) that monitor and control critical infrastructure were publically announced over the last few years. Almost without exception, the proposed security solutions focus on preventing unauthorized access to the industrial control systems (ICS) at various levels – the defense in depth approach. While useful, it does not address the problem of making the systems more capable of responding to the malicious actions of an attacker once they have gained access to the system. The first step in making an ICS more resilient to an attacker is identifying the cyber security vulnerabilities the attacker can …

Cherenkov-Phase-Matched Nonlinear Optical Detection And Generation Of Terahertz Radiation Via Gaas With Metal-Coating, Ramon M.

Terahertz (THz) wave detection and emission via Cherenkov-phase-matched nonlinear optical effects at 1.55-μm optical wavelength were demonstrated using a GaAs with metal-coating (M-G-M) and bare GaAs as a reference sample in conjunction with a metallic tapered parallel-plate waveguide (TPPWG). The metal-coated GaAs is superior to the bare wafer both as a THz electro-optic detector and as an emitter. Significant improvements in the detection and emission efficiency were obtained by utilizing a metal-coating due to better confinement and lower loss of the THz waves propagating in the M-G-M compared with bare GaAs.

Humanization Through Action Research As Methodology, Jeffrey D. Radloff, Cole Joslyn, Brenda Capobianco

The Qualitative Report

The purpose of this action research study was to critically examine the use of action research as a mechanism to enhance graduate students’ development as emerging qualitative researchers. Although action research has been recognized as an effective means of transforming teaching practices, studies examining its use among graduate students learning to become qualitative researchers are lacking. Participants profiled in this study include two graduate students and one teacher educator. The context of the study was a graduate level course on action research where all three participants identified starting points, employed distinct action strategies, engaged in sustained, critical reflection, and developed …

Leading Without Permission, Robin Hummel

Occasional Paper Series

Author Robin Hummel makes an emphatic, persuasive plea for teachers to seize the reins of instructional leadership and take responsibility - even in the face of recalcitrant administrators and increasingly prescriptive curricula - for their own professional learning and growth. She makes the case for action research as a particularly potent professional development tool, and shows how it serves to liberate teachers from inertia and dependency.

Ask Not What Fhs Can Do For You, But What You Can Do For Fhs, Jessica Endlich Winkler

Occasional Paper Series

Jessica Endlich brings the reader into intimate contact with the faculty of a small, urban high school which depends heavily on voluntary teacher leadership, and finds itself straining against the limits of capacity. Her candid interviews show vividly the tensions that exist when there is never enough time, support, appreciation, and equity to turn a wonderful idea into reality. She suggests some baseline, common-sense strategies to enable teachers to lead without sacrificing their students or their own personal lives.

Why Consumers Disclose Their Tourism Experiences On Tourism Social Networking Sites: Multiple Theoretical Perspectives, Junshu Zhang

USF Tampa Graduate Theses and Dissertations

Tourism social networking sites (SNSs) are websites that provide users with templates for describing their travel experiences and an infrastructure to share such travel posts with a network of like-minded individuals. Tourism SNSs represent an important advertising channel for the tourism industry, as they may assist travelers in selecting destinations and planning vacations on the basis of other travelers’ experiences, which may further stimulate travel and generate income for the tourism industry (Yazdanifard & Yee, 2014). User-generated content (UGC) in the form of travel posts is the core offering and key success factor of tourism SNSs. Travel posts constitute a …

Prevalence Of And Risk Factors For Adolescent Obesity In Tennessee Using The 2010 Youth Risk Behavior Survey (Yrbs) Data: An Analysis Using Weighted Hierarchical Logistic Regression, Shimin Zheng, Nicole Holt, Jodi L. Southerland, Yan Cao, Trevor Taylor, Deborah L. Slawson, Mark Bloodworth

ETSU Faculty Works

Background: The rate of adolescent overweight and obesity has more than quadrupled over the past few decades, and has become a major public health problem [1]. In 2011, 55% of 12-19 year olds in the United States (U.S.) were overweight or obese [2]. Adolescence is a pivotal time in which many health risk behaviors such as tobacco, alcohol, and drug use are initiated. Such health risk behaviors have been significantly associated with overweight and obesity among adolescents.

Objective: The purpose of this study is to evaluate the relationship between obesity and the health risk behaviors most commonly associated with premature …

Metal-Organic Frameworks As Potential Platforms For Carbon Dioxide Capture And Chemical Transformation, Wenyang Gao

USF Tampa Graduate Theses and Dissertations

The anthropogenic carbon dioxide (CO₂) emission into the atmosphere, mainly through the combustion of fossil fuels, has resulted in a balance disturbance of the carbon cycle. Overwhelming scientific evidence proves that the escalating level of atmospheric CO₂ is deemed as the main culprit for global warming and climate change. It is thus imperative to develop viable CO₂ capture and sequestration (CCS) technologies to reduce CO₂ emissions, which is also essential to avoid the potential devastating effects in future. The drawbacks of energy-cost, corrosion and inefficiency for amine-based wet-scrubbing systems which are currently used in industry, …

The inverse semigroups are semigroups studied by many algebraists. In this paper we will formulate and prove some other propositions on these semigroups. So we will prove two propositions concerning the closure of a subsemigroup of a given inverse semigroup S, within the meaning introduced by Schein in 1962, two propositions on the group congruence on a normal subsemigroup of the inverse semigroup S, and a proposition about closed subsemigroup assertion of an inverse semigroup S.
