Classifying Idiomatic And Literal Expressions Using Vector Space Representations, Jing Peng, Anna Feldman, Hamza Jazmati

Department of Computer Science Faculty Scholarship and Creative Works

We describe an algorithm for automatic classification of idiomatic and literal expressions. Our starting point is that idioms and literal expressions occur in different contexts. Idioms tend to violate cohesive ties in local contexts, while literals are expected to fit in. Our goal is to capture this intuition using a vector representation of words. We propose two approaches: (1) Compute inner product of context word vectors with the vector representing a target expression. Since literal vectors predict well local contexts, their inner product with contexts should be larger than idiomatic ones, thereby telling apart literals from idioms; and (2) Compute …

Multi-Mode And Single Mode Polymer Waveguides And Structures For Short-Haul Optical Interconnects, Kevin L. Kruse

Dissertations, Master's Theses and Master's Reports - Open

Single mode and multi-mode polymer optical waveguides are a viable solution for replacing copper interconnects as high speed and large bandwidth short-haul optical interconnects in next-generation supercomputers and data servers. A precision laser direct writing method is implemented for producing various single mode and multi-mode polymer waveguide structures and their performance is evaluated experimentally showing agreement with theoretically developed models. The laser direct writing method is the optimal solution for low-rate cost-effective prototyping and large area panel production.

A single mode polymer waveguide bridge module for silicon to glass optical fibers is designed, modeled, fabricated, and measured. The bridge module …

Applying Hierarchical Task Analysis Method To Discovery Layer Evaluation, Marlen Promann, Tao Zhang

Libraries Faculty and Staff Scholarship and Research

While usability tests have been helpful in evaluating the success or failure of implementing discovery layers in the library context, the focus of usability tests has remained on the search interface rather than the discovery process for users. The informal site-­‐ and context specific usability tests have offered little to test the rigor of the discovery layers against the user goals, motivations and workflow they have been designed to support. This study proposes hierarchical task analysis (HTA) as an important complementary evaluation method to usability testing of discovery layers. Relevant literature is reviewed for the discovery layers and the HTA …

May You Walk In Beauty: The Decline Of Navajo Land And Culture, Jocelyn Catterson

Undergraduate Theses, Professional Papers, and Capstone Artifacts

The Navajo homeland, Dinetah, is bordered by four mountains that are sacred to the Navajo people: two in Colorado, one in New Mexico, and one in Arizona. Historically, Navajo medicine men have traveled to these mountains to renew prayers and collect medicinal herbs. Today, the mountains, which exist outside of the reservation boundaries, are used for resource extraction and various recreational pursuits. While many Navajo are fighting for the protection of these sacred lands and their traditional culture, others are disinterested. Traditional practices and beliefs are slowly disappearing within the Navajo Nation. The land-use issues associated with these sacred mountains …

Employees’ Social Networking Site Use Impact On Job Performance: Evidence From Pakistan, Murad Moqbel, Fizza Aftab

Information Systems Faculty Publications

This paper reinvestigates the impact of social networking site use by employees on job performance by conducting a methodological replication of Moqbel, Nevo, and Kock (2013) using samples (N=139) from Pakistan. In both studies, social networking site use has significant effects on organizational commitment and job satisfaction, and job satisfaction also has a significant impact on job performance and organizational commitment. In comparison with the U.S., we find that social networking site use in Pakistan has no significant impact on job performance through the mediating effect of job satisfaction, yet has a significant effect on organizational commitment and job satisfaction. …

Project Maelstrom: Forensic Analysis Of The Bittorrent-Powered Browser, Jason Farina, M-Tahar Kechadi, Mark Scanlon

Journal of Digital Forensics, Security and Law

In April 2015, BitTorrent Inc. released their distributed peer-to-peer powered browser, Project Maelstrom, into public beta. The browser facilitates a new alternative website distribution paradigm to the traditional HTTP-based, client-server model. This decentralised web is powered by each of the visitors accessing each Maelstrom hosted website. Each user shares their copy of the website;s source code and multimedia content with new visitors. As a result, a Maelstrom hosted website cannot be taken offline by law enforcement or any other parties. Due to this open distribution model, a number of interesting censorship, security and privacy considerations are raised. This paper explores …

Dynamic Ocean Management: Defining And Conceptualizing Real-Time Management Of The Ocean, Sara M. Maxwell, Elliot L. Hazen, Rebecca L. Lewison, Danial C. Dunn, Helen Bailey, Steven J. Bograd, Dana K. Briscoe, Sabrina Fossette, Alistair J. Hobday, Meredith Bennett

Biological Sciences Faculty Publications

Most spatial marine management techniques (e.g., marine protected areas) draw stationary boundaries around often mobile marine features, animals, or resource users. While these approaches can work for relatively stationary marine resources, to be most effective marine management must be as fluid in space and time as the resources and users we aim to manage. Instead, a shift towards dynamic ocean management is suggested, defined as management that rapidly changes in space and time in response to changes in the ocean and its users through the integration of near real-time biological, oceanographic, social and/or economic data. Dynamic management can refine the …

Assessing Clinical Software User Needs For Improved Clinical Decision Support Tools, Kimberly B. Denney

Walden Dissertations and Doctoral Studies

Consolidating patient and clinical data to support better-informed clinical decisions remains a primary function of electronic health records (EHRs). In the United States, nearly 6 million patients receive care from an accountable care organization (ACO). Knowledge of clinical decision support (CDS) tool design for use by physicians participating in ACOs remains limited. The purpose of this quantitative study was to examine whether a significant correlation exists between characteristics of alert content and alert timing (the independent variables) and physician perceptions of improved ACO quality measure adherence during electronic ordering (the dependent variable). Sociotechnical theory supported the theoretical framework for this …

Understanding Vulnerability In Alaska Fishing Communities: A Validation Methodology For Rapid Assessment Of Well-Being Indices, Conor M. Maguire

All Master's Theses

Social well-being indices measure how fishing communities are likely to be affected by social-ecological perturbations, and are a significant tool to identify the primary issues influencing communities’ sustained participation in fishing activities. In an attempt to further our understanding of how communities are affected by such perturbations, we have developed a rapid assessment methodology to test the external validity of a set of well-being indices that measure community vulnerability. This methodology informs how well such indices reflect the communities they represent by measuring elements of well-being through field observations, and comparing them to corresponding index components created from secondary data …

Loyalty Cards And The Problem Of Captcha: 2nd Tier Security And Usability Issues For Senior Citizens, David M. Cook, Apoorv Kumar, Charwina Unmar-Satiah

Australian Information Security Management Conference

Information Security often works in antipathy to access and useability in communities of older citizens. Whilst security features are required to prevent the disclosure of information, some security tools have a deleterious effect upon users, resulting in insecure practices. Security becomes unfit for purpose where users prefer to abandon applications and online benefits in favour of non-digital authentication and verification requirements. For some, the ability to read letters and symbols from a distorted image is a decidedly more difficult task than for others, and the resulting level of security from CAPTCHA tests is not consistent from person to person. This …

Is The Internet The Main Medium Of Transmitting Terrorism?, Hatem El Zein

Australian Information Warfare and Security Conference

The influx of virtual media platforms has allowed extremists and terrorists to transmit their messages to wider audiences without passing through a gatekeeper or being a subject to editorial policies existed in traditional media outlets. Thus, extremists and terrorists exploit virtual media platforms to report their actions; propagate their ideologies and ultimately to boost their objectives, because these mediums enabled them to have control over time and space. As a result, some governments work to deprive extremists and terrorists from this 'oxygen' through monitoring the cyberspace to block the suspected virtual media platforms. The reactions of some governments to face …

Intra- And Inter-Seasonal Variability Of Supra-Glacial 1 Streams And Lakes Over The West Greenland Ice Sheet 2 From High-Resolution Satellite Optical Data, Michael Gregory Brown

Dissertations and Theses

The Greenland ice sheet (GrIS) is one of the largest glacial ice masses on Earth, second only to the Antarctic ice sheet. The surface hydrology of the GrIS plays a crucial role on the surface energy and mass balance budgets of the ice sheet as a whole. Surface water, known as supra-glacial water, is seasonally found in the ablation zone and feeds the en-glacial and sub-glacial hydrological environments of the ice sheet. The spatial distribution of surface streams is poorly understood and their temporal variability is (to our knowledge) unknown. One of the reasons for the lack of knowledge on …

Self-Reported Experiences Of Climate Change In Nigeria: The Role Of Personal And Socio-Environmental, Idowu Ajibade, Frederick Ato Armah, Vincent Kuuire, Isaac Luginaah, Gordon Mcbean

Geography Faculty Publications and Presentations

In this study, we examined the individual and socio-environmental factors that mediate differential self-reported experiences of climate change in coastal communities in Lagos, Nigeria. Binary complementary log-log multivariate regression was used to model residents’ experiences of changing rainfall patterns, ocean surges, and flood events. An analysis of both compositional and contextual factors showed that there were urban communities where vulnerability to flooding tends to be clustered, and that this was not fully explained by the characteristics of the people of whom the community was composed. This study, thus, underscores the importance and complex nature of the interaction between personal and …

The oil sands region in northeast Alberta, Canada is an area of interest for a few reasons; primarily because of the vast reserves of bitumen and the environmental cost associated with developing this resource. An increase in global oil demand has established …

Object-Based Classification Of Earthquake Damage From High-Resolution Optical Imagery Using Machine Learning, James Bialas

Dissertations, Master's Theses and Master's Reports - Open

Object-based approaches to the segmentation and supervised classification of remotely-sensed images yield more promising results compared to traditional pixel-based approaches. However, the development of an object-based approach presents challenges in terms of algorithm selection and parameter tuning. Subjective methods and trial and error are often used, but time consuming and yield less than optimal results. Objective methods are warranted, especially for rapid deployment in time sensitive applications such as earthquake induced damage assessment.

Our research takes a systematic approach to evaluating object-based image segmentation and machine learning algorithms for the classification of earthquake damage in remotely-sensed imagery using Trimble’s eCognition …

The Role Of Hybridization And The United States Fish And Wildlife Service Biologists’ Discretion In The Implementation Of The Endangered Species Act, Jennifer F. Lind-Riehl

Dissertations, Master's Theses and Master's Reports - Open

The Endangered Species Act (ESA) requires that the “best available scientific and commercial data” be used to enable the protection of critically imperiled species from extinction and preserve biodiversity. However, the ESA does not provide specific guidance on how to apply this mandate. In addition, the interpretation of scientific data can be uncertain and controversial, particularly regarding species delineation and hybridization issues. US Fish and Wildlife Service (FWS) field biologists must decide what the best science is and how to interpret and apply it in their recommendations. As a result, FWS field biologists often have considerable discretion when it comes …

Framing The Question, "Who Governs The Internet?", Robert J. Domanski

Publications and Research

There remains a widespread perception among both the public and elements of academia that the Internet is “ungovernable”. However, this idea, as well as the notion that the Internet has become some type of cyber-libertarian utopia, is wholly inaccurate. Governments may certainly encounter tremendous difficulty in attempting to regulate the Internet, but numerous types of authority have nevertheless become pervasive. So who, then, governs the Internet? This book will contend that the Internet is, in fact, being governed, that it is being governed by specific and identifiable networks of policy actors, and that an argument can be made as to …

Looking Beyond Fossil Fuel Divestment: Combating Climate Change In Higher Education, Robin Xu

Pomona Senior Theses

The young fossil fuel divestment movement is altering the landscape of climate change activism on US campuses. Student-run divestment campaigns are now pushing for institutions of higher education to withdraw their investments from the top 200 public fossil fuel companies. Despite student fervor, however, divestment has remained a controversial tactic for combating climate change. The first half of this thesis examines the stated motives of a selection of institutions that have officially agreed or declined to divest, and investigates the hypothesis that pushing for divestment alone will not achieve broad success because it does not appeal to a wide enough …
