Both classes completed a pre and post-test. The researcher compared the growth of both classes. Results of the study showed that incorporating assessment literacy techniques such as student friendly learning targets, reflection, self-assessment, …


Have Video Gaming Revenues Led To An Increase In Municipal Services In Illinois?, Christopher Dudzinski Dec 2017

Have Video Gaming Revenues Led To An Increase In Municipal Services In Illinois?, Christopher Dudzinski

All Student Theses and Dissertations

In 2009, the Illinois General Assembly passed the Video Gaming Act, the largest gambling expansion in the state’s history. That expansion allowed locations within Illinois to have five Video Gaming Terminals (VGT) within their business, similar to the slot machines previously only seen at state casinos. These terminals arrived under much scrutiny, as scholars and citizens alike were concerned with the social negatives attached to gambling facilities. Previous research points out many of the societal connotations that comes along with Video Gaming such as negative externalities associated with bankruptcy and addiction, but has yet to analyze the impact on the …

Inside The Grassroots Money Machine, Elizabeth Tung

Capstones

In the year since Donald Trump’s election, grassroots canvassing groups have generated millions of dollars for nonprofits like Planned Parenthood and the ACLU. These groups’ growing profile correlates with a post-election spike in liberal giving, and the rise of face-to-face fundraising in the US. But despite their progressive affiliations, several groups have come under fire for abusive labor practices and a lack of financial transparency. This piece looks at two of the biggest players in the canvassing industry, the Fund for the Public Interest and Grassroots Campaigns. Both groups are headed by the same person - a man named Doug …


Hazmat Storage Near Nyc Waterways Endangers Communities, Brett E. Dahlberg, Nicole Acevedo Dec 2017

Hazmat Storage Near Nyc Waterways Endangers Communities, Brett E. Dahlberg, Nicole Acevedo

Capstones

New York City has 520 miles of shoreline--that’s more than Miami and Los Angeles combined. These waterfronts are home to some of the city’s most polluted sites because major part of it is zoned for industrial use. Dozens of industrial plants in this area store toxic chemicals in flood zones: substances that are hazardous to our health, like Benzene, which is used in rocket fuel, toluene, a paint thinner, and lead a neurotoxin. In a flood, these chemicals can easily get caught up in moving waters and pollute entire neighborhoods.

That’s exactly what happened when Hurricane Sandy hit in 2012. …

In theory, consumer price index and the producer price index should exist in a sequence and conduction relationship. But the data …


Youth Sport Development Pathways And Experiences Of Ncaa Division I Women's College Soccer Players, Emily Hardell Dec 2017

Youth Sport Development Pathways And Experiences Of Ncaa Division I Women's College Soccer Players, Emily Hardell

Master's Theses

As youth sport has become increasingly professionalized, many believe that the route to elite level play is through early specialization. Early specialization is a contentious issue, and many risk factors have been associated with high levels and intensities of training in youth. Youth today participate in highly competitive sport in pursuit of elite levels of play, recognition, and financial gain. Early specialization is thought to be a requirement for advancement, yet little is known about the early experiences of team sport athletes who grew up in the US. This is the story of 15 elite female athletes who “made it” …


The Common Lot Of Nature: The Stoic Concept Of Death In The Writings Of St. Ambrose, Nathan Michael Falls Hall Dec 2017

The Common Lot Of Nature: The Stoic Concept Of Death In The Writings Of St. Ambrose, Nathan Michael Falls Hall

Master's Theses

The Common Lot of Nature is a comparative analysis which questions the completeness of St. Ambrose’s Christian faith. The comparison focuses specifically on notions of death, and how one should deal with its presence in one’s life. This emphasis was chosen because Ambrose was a Christian bishop who was heavily influenced by Stoicism, and these two worldviews held contrasting beliefs on how death fits into the lives of human beings. The paper begins with an outline of other research regarding Stoicism or its potential connections with Christianity. The following two sections discuss how Stoics and 4th century Christians conceptualized death …


The Sediment Analysis Of A Prehistoric Shell Midden From Nevis, West Indies, Erika Harvey Dec 2017

The Sediment Analysis Of A Prehistoric Shell Midden From Nevis, West Indies, Erika Harvey

Master's Theses

Archaeology in the Caribbean is a growing area of research. The last few decades have revealed a series of Ceramic Age sites +600BCE - 1620CE along the Windward coast of Nevis, West Indies. These sites must be excavated and examined soon, due to the effects of erosion and sea level rise. It is pertinent to explore and expand the knowledge of the prehistoric Carib peoples, if we are truly going to understand the history of the Caribbean. By bridging aspects of science and humanities through geoarchaeological methods, this project is aiming for an interdisciplinary approach to better understand the pre-Colonial …


Binding Affinity And Specificity Of Sh2 Domain Interactions In Receptor Tyrosine Kinase Signaling Networks, Tom Ronan Dec 2017

Binding Affinity And Specificity Of Sh2 Domain Interactions In Receptor Tyrosine Kinase Signaling Networks, Tom Ronan

McKelvey School of Engineering Graduate Student Theses & Dissertations

Receptor tyrosine kinase (RTK) signaling mechanisms play a central role in intracellular signaling and control development of multicellular organisms, cell growth, cell migration, and programmed cell death. Dysregulation of these signaling mechanisms results in defects of development and diseases such as cancer. Control of this network relies on the specificity and selectivity of Src Homology 2 (SH2) domain interactions with phosphorylated target peptides. In this work, we review and identify the limitations of current quantitative understanding of SH2 domain interactions, and identify severe limitations in accuracy and availability of SH2 domain interaction data. We propose a framework to address some …


Learning From Zũni War Gods Repatriating Alternative Dispute Resolution For Practice And Research, Alexandra Crampton Dec 2017

Learning From Zũni War Gods Repatriating Alternative Dispute Resolution For Practice And Research, Alexandra Crampton

Social and Cultural Sciences Faculty Research and Publications

This article applies lessons learned from the Zũni people of the southwestern United States about successful and sustainable intervention as a metaphor to address common tensions among alternative dispute resolution (ADR) scholars and practitioners. These tensions are found in professionalisation, institutionalisation and identification of best practices. Through example of Zũni efforts to repatriate sacred artefacts known as Ahuy: da, I argue that ADR is an intervention that works best through direct and ongoing dialogue rather than rigid adherence to a set of standards. The problem lies in how such adherence can limit and distort rather than inform or support best …


Horizontal Cybersurveillance Through Sentiment Analysis, Margaret Hu Dec 2017

Horizontal Cybersurveillance Through Sentiment Analysis, Margaret Hu

William & Mary Bill of Rights Journal

This Essay describes emerging big data technologies that facilitate horizontal cybersurveillance. Horizontal cybersurveillance makes possible what has been termed as “sentiment analysis.” Sentiment analysis can be described as opinion mining and social movement forecasting. Through sentiment analysis, mass cybersurveillance technologies can be deployed to detect potential terrorism and state conflict, predict protest and civil unrest, and gauge the mood of populations and subpopulations. Horizontal cybersurveillance through sentiment analysis has the likely result of chilling expressive and associational freedoms, while at the same time risking mass data seizures and searches. These programs, therefore, must be assessed as adversely impacting a combination …


Small Arms: An Applied Approach To Children In Armed Conflict Prevention Initiatives In Africa, Tristan Burger Dec 2017

Small Arms: An Applied Approach To Children In Armed Conflict Prevention Initiatives In Africa, Tristan Burger

Master's Theses

For centuries, children have been used in times of war—serving as porters, cooks, spies, sex slaves, and soldiers. Unfortunately, this phenomenon is still pervasive today with an estimated 300,000 children involved in armed conflict as of 2015. This applied project examines a possible method for preventing the illegal practice of using children in combat by employing a new technology centered on community-based early warning theories. I seek to understand if implementing a text-based, mobile crowdsourcing platform in remote communities in Sub-Saharan Africa will be successful in predicting Lord’s Resistance Army raids, thereby reducing the number of children abducted and/or forcibly …


Urbanization, Land Rights And Development: A Case Study Of Waterfront Communities In Lagos, Nigeria., Gideon Olaniyi Omoniyi Dec 2017

Urbanization, Land Rights And Development: A Case Study Of Waterfront Communities In Lagos, Nigeria., Gideon Olaniyi Omoniyi

Master's Theses

The aim of this study is to examine the root causes of forced evictions and displacement through the current urbanization process in Lagos, Nigeria. My particular attention is devoted to the legal complexities and how ethnolinguistic identities shape land laws, influence land tenure, and construct urban citizenship. Through this process, competing claims to land ownership provide fertile ground for forced evictions and displacement. Existing scholars suggest that poor urban residents lack rights to stay in their neighborhoods, while a powerful capitalist class has emerged and dispossessed the poor from their lands. Yet these existing approaches derived from the neoclassical and …


Exploring Employment Equity: Diversity & Inclusion In Canada’S Legislation & Policy, Vanessa Toussaint Miller Dec 2017

Exploring Employment Equity: Diversity & Inclusion In Canada’S Legislation & Policy, Vanessa Toussaint Miller

Master's Theses

Multiculturalism is considered very much a part of Canada’s national heritage and identity, becoming the first nation to adopt multiculturalism as an official policy in 1971. Over the last 40 years, the Canadian population has undergone significant changes bringing in immigrants with different cultures, ideologies, religions and ways of life. Despite the various changes in society, the multiculturalism policies have remained the same. This thesis examines Canada’s Employment Equity-a policy intended to eliminate systemic discrimination in the workplace-and its effectivity at creating a diverse and inclusive workforce.

How Patriotic Are Albanians? The Comparative Study Of Patriotic Attitudes In Albania And The Albanian Diaspora, Anxhela Spahiu

Master's Theses

In today’s post-modern digital world, patriotism may not be as prevalent as in the past. In this thesis, my principal aim is to investigate to what extent Albanians, a nationality to which I belong, identify with a patriotic attitude toward Albania. I chose to focus not only on Albanians who live in the diaspora, like myself, but also on Albanians who live in Albania. I believe that to understand national pride to its fullest, you must study the attitudes of those who live in the country of origin as well as of those who live in the diaspora. Many people …

Migrant Ridesharing Drivers In San Francisco: A Case Of Blocked Mobility?, Shireen Tofig Dec 2017

Migrant Ridesharing Drivers In San Francisco: A Case Of Blocked Mobility?, Shireen Tofig

Master's Theses

Migrants have long turned to self-employment in host country labor markets due to not only racial and ethnic prejudices, but also issues of local language proficiency and lack of recognition of the academic degree from the sending country. The taxi industry, one particular occupational niche dominated by migrants, has long been studied by scholars. However, the industry has evolved into a newer and understudied form of transportation: ridesharing. This study argues that in the case of the ridesharing industry, drivers did indeed turn to the occupation because of factors such as insufficient English language level and foreign academic degrees, but …


Japan's Employment 'Catch-22': The Impact Of Working Conditions For Women In Japan On Japan's Demographic Population Crisis, Mary Perkins Dec 2017

Japan's Employment 'Catch-22': The Impact Of Working Conditions For Women In Japan On Japan's Demographic Population Crisis, Mary Perkins

Master's Theses

This thesis examines Japan’s aging population crisis and gender inequalities in the workplace. This topic presents an interesting and challenging phenomenon for Japan, as Japan’s economy and technology have developed more rapidly than almost any other country, establishing Japan as one of the Group of Seven industrialized nations. Yet Japan still significantly lags behind other industrialized nations when it comes to women’s rights and opportunities for advancement in the workplace. This is in turn hampering efforts for Japan to address a population crisis, with an older population growth rate far outpacing the growth of demographic groups that would support the …

Comparison Of The Bi-Directional Performance Of Micro-Channel Sieve And Thin-Film Time Peripheral Nerve Interfaces, Robert Coker Dec 2017

Comparison Of The Bi-Directional Performance Of Micro-Channel Sieve And Thin-Film Time Peripheral Nerve Interfaces, Robert Coker

McKelvey School of Engineering Graduate Student Theses & Dissertations

Sophisticated motorized prosthetic limbs contain multiple degrees of freedom of motion as well as embedded pressure and angle transducers to provide sensory feedback in amputees. Although several central neural recording and stimulation modalities exist for both controlling these motions and providing sensory feedback from a prosthetic limb, directly interfacing the peripheral nerves which originally innervated the limb has many advantages. A difficulty with this bi-directional approach is that electrically stimulating axons to provide haptic feedback creates stimulation artifacts at neighboring recording sites within the nerve that are several orders of magnitude larger than the electroneurogram used for control. In this …


Mechanics Of The Developing Brain: From Smooth-Walled Tube To The Folded Cortex, Kara Ellspermann Garcia Dec 2017

Mechanics Of The Developing Brain: From Smooth-Walled Tube To The Folded Cortex, Kara Ellspermann Garcia

McKelvey School of Engineering Graduate Student Theses & Dissertations

Over the course of human development, the brain undergoes dramatic physical changes to achieve its final, convoluted shape. However, the forces underlying every cinch, bulge, and fold remain poorly understood. This doctoral research focuses on the mechanical processes responsible for early (embryonic) and late (preterm) brain development.

First, we examine early brain development in the chicken embryo, which is similar to human at these stages. Research has primarily focused on molecular signals to describe morphogenesis, but mechanical analysis can also provide important insights. Using a combination of experiments and finite element modeling, we find that actomyosin contraction is responsible for …


Bio-Inspired Multi-Spectral And Polarization Imaging Sensors For Image-Guided Surgery, Nimrod Missael Garcia Dec 2017

Bio-Inspired Multi-Spectral And Polarization Imaging Sensors For Image-Guided Surgery, Nimrod Missael Garcia

McKelvey School of Engineering Graduate Student Theses & Dissertations

Image-guided surgery (IGS) can enhance cancer treatment by decreasing, and ideally eliminating, positive tumor margins and iatrogenic damage to healthy tissue. Current state-of-the-art near-infrared fluorescence imaging systems are bulky, costly, lack sensitivity under surgical illumination, and lack co-registration accuracy between multimodal images. As a result, an overwhelming majority of physicians still rely on their unaided eyes and palpation as the primary sensing modalities to distinguish cancerous from healthy tissue. In my thesis, I have addressed these challenges in IGC by mimicking the visual systems of several animals to construct low power, compact and highly sensitive multi-spectral and color-polarization sensors. I …
