Rpsftm: An R Package For Rank Preserving Structural Failure Time Models, Annabel Allison, Ian R. White, Simon Bond

The R Journal

Treatment switching in a randomised controlled trial occurs when participants change from their randomised treatment to the other trial treatment during the study. Failure to account for treatment switching in the analysis (i.e. by performing a standard intention-to-treat analysis) can lead to biased estimates of treatment efficacy. The rank preserving structural failure time model (RPSFTM) is a method used to adjust for treatment switching in trials with survival outcomes. The RPSFTM is due to Robins and Tsiatis (1991) and has been developed by White et al. (1997, 1999).

The method is randomisation based and uses only the randomised treatment group, …

Bayesian Regression Models For Interval-Censored Data In R, Clifford Anderson-Bergman

The R Journal

The package icenReg provides classic survival regression models for interval-censored data. We present an update to the package that extends the parametric models into the Bayesian framework. Core additions include functionality to define the regression model with the standard regression syntax while providing a custom prior function. Several other utility functions are presented that allow for simplified examination of the posterior distribution.

Arulesviz: Interactive Visualization Of Association Rules With R, Michael Hahsler

The R Journal

Association rule mining is a popular data mining method to discover interesting relation ships between variables in large databases. An extensive toolbox is available in the R-extension package arules. However, mining association rules often results in a vast number of found rules, leaving the analyst with the task to go through a large set of rules to identify interesting ones. Sifting manually through extensive sets of rules is time-consuming and strenuous. Visualization and especially interactive visualization has a long history of making large amounts of data better accessible. The R-extension package arulesViz provides most popular visualization techniques for association …

Jittery Gauges: Combating The Polarizing Effect Of Political Data Visualizations Through Uncertainty, Bethany Blaire Hardy

Theses and Dissertations

Since the late 1800s, public data visualizations displaying election forecasts and results—such as the red and blue map of the United State—have presented an irreparably divided country. However, on November 8, 2016, the New York Times published a data visualization on their live presidential forecast page that broke over a century of visual expectations, inspiring many to tweet reactions to what popular media has dubbed the "jittery gauges." Not surprisingly, the tweets about this unique and difficult-to-interpret display were mostly negative. This paper argues, though, that the negative feedback indicates that the gauges, while imperfect, represent an important step away …

The specimens excavated at Carnegie Quarry are displayed and curated in 20 repositories, most in North America. Data on these specimens in the forms of notes, photographs, publications, field maps, and so on, are scattered in an array of formats and institutions. The primary goal of this thesis is to develop a database linking these data with a digital map (GIS system) to make them readily accessible. To this end, a relational database was created using …

Effects Of Teacher Praise And Reprimand Rates On Classroom Engagement And Disruptions Of Elementary Students At Risk For Emotional And Behavioral Disorders, Kade Rolan Downs

Theses and Dissertations

In the United States educators often feel underprepared to manage student behavior in the classroom, which management is crucial for students with or at risk for Emotional and Behavioral Disorders (EBD) to learn effectively. Research on School-wide Positive Behavior Support (SWPBS) programs has reflected how effective simple principles, such as increasing teacher praise and decreasing teacher reprimands, can be. The current study is a secondary analysis of data originally gathered from 65 teachers and 239 students across three states. Results of these analyses bring principles of effective SWPBS programs and educator needs together by identifying how teacher behaviors correlated with …

Campus Climate, Peer Dispositions, And The Inclusion Of Lgbq And Transgender Students At A Jesuit University, Cassie L. Barnhardt, Jodi Linley, Amanda L. Mollet, Carson W. Phillips, Ryan L. Young

Jesuit Higher Education: A Journal

Using a campus climate framework, this study identifies students who hold positive dispositions towards lesbian, gay, bisexual, queer (LGBQ) and transgender students at a Jesuit university. Findings reveal that just more than one-quarter of students hold positive dispositions toward LGBQ and transgender students and desire that the campus work towards being more inclusive towards this group. Our binomial logistic regression of 602 student responses demonstrated that women are more inclined to hold positive dispositions. Similarly, students who agree that non-Catholics should be supported by their campus are also inclined to hold positive dispositions toward LGBQ and transgender students. Further, we …

Hemodynamic Characteristics Of Ruptured And Unruptured Multiple Aneurysms At Mirror And Ipsilateral Locations, Ravi Doddasomayajula, Bong Jae Chung, Fernando Mut, Carlos M. Jimenez, Farid Hamzei-Sichani, Christopher M. Putman, Juan R. Cebral

Department of Applied Mathematics and Statistics Faculty Scholarship and Creative Works

BACKGROUND AND PURPOSE: Different hemodynamic patterns have been associated with aneurysm rupture. The objective was to test whether hemodynamic characteristics of the ruptured aneurysm in patients with multiple aneurysms were different from those in unruptured aneurysms in the same patient.

MATERIALS AND METHODS: Twenty-four mirror and 58 ipsilateral multiple aneurysms with 1 ruptured and the others unruptured were studied. Computational fluid dynamics models were created from 3D angiographies. Case-control studies of mirror and ipsilateral aneurysms were performed with paired Wilcoxon tests.

RESULTS: In mirror pairs, the ruptured aneurysm had more oscillatory wall shear stress (P = .007) than the …

Sharing Responsibility For Divesting From Fossil Fuels, Eric S. Godoy

Faculty Publications - Philosophy

Governments have been slow to address climate change. If non-governmental agents share a responsibility in light of the slow pace of government action then it is a collective responsibility. I examine three models of collective responsibility, especially Iris Young's social connection model, and assess their value for identifying a collective, among all emitters, that can share responsibility. These models can help us better understand both the growth of the movement to divest from fossil fuels and the nature of responsibility for collective action problems. Universities and colleges share a responsibility because they occupy similar positions of, among other things, power …

Interviews And Conversations About Leaving Services (Icals): A Review Of Resources After Tanf, Maria C. Cole

Social Work Theses - Archive

The Temporary Assistance for Needy Families (TANF) policy is designed to protect the nation’s most vulnerable families from severe hardship. The policy encourages moving people from “welfare to work” and improving child welfare. TANF, though, has remained largely unchanged since its adoption in 1996 despite persistent poverty nationwide and worsening poverty in the Dallas-Fort Worth metropolitan area. Consequently, TANF has not effectively responded to poverty nor has it improved child welfare. The researcher conducted a comprehensive literature review which identified employment barriers found to affect families leaving TANF services. Several studies illuminated that mental or behavioral health, substance abuse, race …

Interdisciplinary Collaboration And Metacognitive Reflection: A Case Study Of Faculty Teaching In Learning Communities, Melissa Perry

English Dissertations - Archive

This qualitative case study examines the nature of faculty collaboration within the context of academic learning communities using third generation activity theory as an organizing framework. First, this study investigates how faculty collaborate across disciplinary lines to create and implement curriculum for paired and team-taught interdisciplinary learning community courses. Furthermore, this study seeks to understand whether these collaborative practices provide opportunities for discipline-based metacognitive reflection. Through the analysis of semi-structured interviews, classroom observations, and course documents, the study findings confirm that learning communities do, in fact, create opportunities for faculty to become more self-aware of their own disciplinary conventions and …

Painting A Picture: Understanding Our Student Parent Profile On Campus, Vicki Squires, Jason Disano

Journal of Global Education and Research

Little information or research exists regarding the profile of student parents on campus even though increasingly more non-traditional and mature students access post-secondary education. This study presents information generated through a telephone survey of students conducted by a research lab on one Canadian campus. The purpose of the research was to uncover more information about this student group with the intent that the data would inform the development of guidelines for allocation of additional childcare spaces on campus as soon as a new childcare centre was completed. Better information on their needs as students and parents would be helpful in …

Slow Down And Smell The Eucalypts: Blue Gum Community School And The Slow Education Movement, Stephen J. Smith

Journal of Global Education and Research

This paper investigates and analyses the features of a non-mainstream pedagogy, educational context and learning environment by presenting a counter-model which contrasts with the currently dominant educational project, an emergent global educational movement known as the Slow Education Movement. It demonstrates how the associated principles and praxes of a particular ethos and its philosophical foundations guide teaching and learning. Set against the background of the Slow Education Movement, the paper draws on a case study to illustrate some of the foundational principles and practices of that movement. The paper outlines the educational ethos, philosophy, processes and practices of Blue Gum …

Wangari Maathai The Educator: Straddling Tradition And Modernity, Namulundah Florence

Journal of Global Education and Research

Wangari Muta Mary Jo Maathai’s (April 1, 1940 – September 25, 2011) public image highlights her nationality, her education both in and outside Kenya, her establishment of the Green Belt Movement (GBM) for which she received a Nobel Peace Prize in 2004, and her political activism. Advocates for female empowerment take solace in success stories like Maathai’s rise from a village girl to become a global icon of leadership. Yet, her mobility was more circumstantial than it was deliberate, and is inseparable from the uneasy compromise between the traditional gender roles of her youth with the critical consciousness nurtured in …

Analytical Technique To Evaluate Impact Of Mutual Coupling On Transmission Line Protection Schemes, Azade Brahman

Electrical Engineering Theses - Archive

While there are numerous literatures that have addressed the impact of mutual coupling on the reliability and security of protection schemes and have provided possible mitigation solutions, there has not been adequate research and documentation presenting a comprehensive analytical approach to 1) estimate the magnitude of mutual coupling and 2) quantify the adverse impact of mutual coupling in real-life scenarios under several system faults across various types of protective elements. This should be considered as the first stage of any mutual coupling related study preceding the second stage in which the mitigation against mutual coupling is to be developed. The …

Bit-Rate Reduction Using Superpixel For 360-Degree Videos - Vr Application, Swaroop Krishna Rao

Electrical Engineering Theses - Archive

Superpixels are applied on the side views of the 2D projected video. Then the video is partitioned into Coding Tree Units (CTUs). The CTUs and the superpixels positions will be compared within the frame of video. During comparison, the following cases will be considered: Case-1: If two or more CTUs are covered by the same superpixel, then the CTUs will be merged into one large coding tree unit. This merged CTU will be called as Intra CTU. Case-2: If one CTU is covered by two or more superpixels, then it will be referred to as Boundary CTU. After finding the …

The Effects Of Reforestation On Mammal Diversity And Abundance In Monteverde, Costa Rica, December 2017, Noelle Pruett

Monteverde Institute: Tropical Ecology and Conservation

Reforestation is an important mechanism in helping previously deforested landscapes recover. However, reforested areas tend to have less diversity in vegetation, due to the fact that humans are not able to replicate the same diversity or pattern of regeneration that would occur naturally. I investigated whether or not these changes in forest types and vegetation affect the diversity and abundance of mammals that inhabit these areas. I used both camera traps and Sherman traps to survey mammals from areas with reforestation and with natural regeneration. I observed a total of 72 mammals from five species in the camera traps. I …

Synchronized Male Cricket Calls In Choruses Of The Cricket Anaxipha Sp., December 2017, Michael Morales

Monteverde Institute: Tropical Ecology and Conservation

In Monteverde, there is a species of cricket within the Genus Anaxipha where males sing in loud choruses at night. I wanted to explore the purpose of this behavior by looking at the call and response activity between individual males. In this experiment, I looked at male responses to manipulations of the species male song, which is composed of two elements. I conducted a series of playback experiments on captive crickets. Responses of test subjects were documented while presenting playbacks of manipulated songs. Each playback treatment had a unique response from the crickets being tested. However, overall, it appears that …

Possible Effects Of Long-Term Weather Changes And Extreme Weather Events On Mice Population Abundances In Monteverde, Costa Rica, December 2017, Emily S. Parker

Monteverde Institute: Tropical Ecology and Conservation

Mice and rat abundance is determined by a multitude of factors, including, but not limited to: climate change, predation, and food availability. In this study, I analyzed the effects of daily and long-term weather on rodent populations to understand a possible decrease in abundance from 2016 to 2017 in Monteverde, Puntarenas, Costa Rica. I took observations of individuals from four different sites: Santa Elena, Bajo del Tigre, Dwight and Rachel Crandell Memorial Reserve, and the Estación Biológica Monteverde. While a considerable number of specimens were captured in Bajo del Tigre, I observed the total abundance of rodents to be significantly …

Anthropology: Undergraduate Student Scholarship

Global Kidney Exchange (GKE) is a program aimed at facilitating trans-national kidney donation. Although its proponents aim at reducing the unmet demand of kidneys in the United States through the trans-nationalization of kidney exchange programs, the World Health Organization (WHO) and The Transplantation Society (TTS) have expressed concerns about its potential effect on black markets of organs and transnational organ trafficking, as well as on low- or middle-income countries health systems. For GKE to be implemented, it would need to be permitted to operate in at least some low- or middle-income countries. What are the right to health implications of …

Building An Albanian Knowledge Graph From Unstructured Text, Hakan Shehu

Theses and Dissertations

We live in the golden area of information. The World Wide web contains a vast amount of unstructured text in different digital formats, including newswire, blogs, email communications, governmental documents, chat logs, and so on. Some of the biggest companies and organizations have created knowledge bases which represent a semantic network of facts, entities and relations between them. Even though this area has been well researched for a considerable time, there is a lack of implementation of such a knowledge extraction for Albanian language. In this thesis we will try to create an Albanian general knowledge graph from unstructured text. …

Megjithatë ka fare pak kërkim në këtë fushë kur vjen fjala tek vendet që ende nuk janë antarësuar në BE por që e aspirojnë këtë antarësim. Ne …

Draps: Dynamic And Resource-Aware Placement Scheme For Docker Containers In A Heterogeneous Cluster, Ying Mao, Jenna Oak, Anthony Pompili, Daniel Beer, Tao Han, Peizhao Hu

Presentations and other scholarship

Virtualization is a promising technology that has facilitated cloud computing to become the next wave of the Internet revolution. Adopted by data centers, millions of applications that powered by various virtual machines improve the quality of services. Although virtual machines are well-isolated among each other, they suffer from redundant boot volumes and slow provisioning time. To address the limitations, containers were born to deploy and run distributed applications without launching entire virtual machines. As a dominant player, Docker is an open-source implementation of container technology. When managing a cluster of Docker containers, the management tool, Swarmkit, does not take the …
