Busting Blocks: Revisiting 47 U.S.C. §230 To Address The Lack Of Effective Legal Recourse For Wrongful Inclusion In Spam Filters, Jonathan I. Ezor

Scholarly Works

This paper discusses the growth and increasing significance of e-mail in the business and personal environment, and how unsolicited bulk commercial e-mail, also known as spam, has become a significant drain on technical and economic resources. It analyzes the statutory and self-help efforts to combat spam, with a specific focus on block lists and automated spam filters, and describes how alleged spammers have brought lawsuits in U.S. courts claiming they had been wrongfully included within block lists and filters. Finally, it describes some possible claims under U.S. law, then argues for a revision to current statutes to mandate a higher …

Rit Influenza Virus Database And Evidence For Differential Selection Pressures On Geographically Distinct Human Influenza A/H3n2 Virus Populations, Bindhu Satheeshkumar Jan 2011

Rit Influenza Virus Database And Evidence For Differential Selection Pressures On Geographically Distinct Human Influenza A/H3n2 Virus Populations, Bindhu Satheeshkumar

Theses

Increasing amounts of data available from influenza virus genome sequencing projects have necessitated the need for centralized repositories for the collection, integration, and dissemination of these data to researchers for further research. The RIT Influenza Virus Database, a complete genome database for influenza viruses, has been created with a web interface so that users could query for viruses of interest and download complete genome sequences and metadata of isolates. The interface of the database is publicly accessible at http://bucatini.bioinformatics.rit.edu/bindhuURMC/. Even though it is known that influenza viruses are under constant evolution at the surface glycoproteins to develop drug resistance or …

The Effect Of High Dose Total Body Irradiation On Acth, Corticosterone, And Catecholamines In The Rat, Eric P. Cohen, Eric D. Bruder, William E. Cullinan, Dana R. Ziegler, Hershel Raff Jan 2011

The Effect Of High Dose Total Body Irradiation On Acth, Corticosterone, And Catecholamines In The Rat, Eric P. Cohen, Eric D. Bruder, William E. Cullinan, Dana R. Ziegler, Hershel Raff

Biomedical Sciences Faculty Research and Publications

Total body irradiation (TBI) or partial body irradiation is a distinct risk of accidental, wartime, or terrorist events. Total body irradiation is also used as conditioning therapy before hematopoietic stem cell transplantation. This therapy can result in injury to multiple tissues and might result in death as a result of multiorgan failure. The hypothalamic–pituitary–adrenal (HPA) axis could play a causative role in those injuries, in addition to being activated under conditions of stress. In a rat model of TBI, we have established that radiation nephropathy is a significant lethal complication, which is caused by hypertension and uremia. The current study …

Periodic Atlas Of The Metroscape: Deciphering Who We Are - Trials And Tribulations Of The American Community Survey, Meg Merrick Jan 2011

Periodic Atlas Of The Metroscape: Deciphering Who We Are - Trials And Tribulations Of The American Community Survey, Meg Merrick

Institute of Metropolitan Studies Publications

This edition of the periodic atlas uses recent American Community Survey (ACS) data to examine the percent of persons living in poverty in the metroscape. This variable, along with the percent foreign born, those with a bachelor's degree or higher, and average commuting time are available for viewing in Google Earth at our website. Perhaps more important than the snapshot we can attempt to capture of poverty in our community, is the caution we can offer to policymakers who may depend on ACS data to address perceived problems. This atlas therefore serves twin purposes: giving our readers the best analysis …

Environmental Migrants And The Future Of The Willamette Valley: A Preliminary Exploration, Alison Wicks Jan 2011

Environmental Migrants And The Future Of The Willamette Valley: A Preliminary Exploration, Alison Wicks

Institute of Metropolitan Studies Publications

This report reviews existing data and research on predicted impacts of climate change in the Northwestern United States, and specifically focuses on the level of preparedness to accommodate new population growth due to climate migration in Oregon’s Willamette Valley. Climate change impacts in Oregon are predicted to be less severe than in other areas of the country. Generally, models project warmer, wetter winters and hotter, drier summers in the Willamette Valley and other areas west of the Cascade Range. This will likely make the Willamette Valley a more desirable place for environmentally displaced people to locate. This report considers how …

Balance Systems And The Variational Bicomplex, Serge Preston Jan 2011

Balance Systems And The Variational Bicomplex, Serge Preston

Mathematics and Statistics Faculty Publications and Presentations

In this work we show that the systems of balance equations (balance systems) of continuum thermodynamics occupy a natural place in the variational bicomplex formalism. We apply the vertical homotopy decomposition to get a local splitting (in a convenient domain) of a general balance system as the sum of a Lagrangian part and a complemental "pure non-Lagrangian" balance system. In the case when derivatives of the dynamical fields do not enter the constitutive relations of the balance system, the "pure non-Lagrangian" systems coincide with the systems introduced by S. Godunov [Soviet Math. Dokl. 2 (1961), 947–948] and, later, asserted as …

Simulation And Emulation Of Massively Parallel Processor For Solving Constraint Satisfaction Problems Based On Oracles, Gunavant Dinkar Chaudhari Jan 2011

Simulation And Emulation Of Massively Parallel Processor For Solving Constraint Satisfaction Problems Based On Oracles, Gunavant Dinkar Chaudhari

Dissertations and Theses

Most part of my thesis is devoted to efficient automated logic synthesis of oracle processors. These Oracle Processors are of interest to several modern technologies, including Scheduling and Allocation, Image Processing and Robot Vision, Computer Aided Design, Games and Puzzles, and Cellular Automata, but so far the most important practical application is to build logic circuits to solve various practical Constraint Satisfaction Problems in Intelligent Robotics. For instance, robot path planning can be reduced to Satisfiability. In short, an oracle is a circuit that has some proposition of solution on the inputs and answers yes/no to this proposition. In other …

Pedagogical Catalysts Of Civic Competence: The Development Of A Critical Epistemological Model For Community-Based Learning, Stephanie Taylor Stokamer Jan 2011

Pedagogical Catalysts Of Civic Competence: The Development Of A Critical Epistemological Model For Community-Based Learning, Stephanie Taylor Stokamer

Dissertations and Theses

Civic competence is critical to the successful functioning of pluralistic democracies. Developing the knowledge, skills, and motivations for effective democratic participation is a national and global imperative that many higher education institutions have embraced through the teaching strategies of community-based learning and service-learning. Yet, scant research literature has focused on the relationship between pedagogical approaches and civic competence outcomes. This five-year longitudinal study of 11,000 students in 700 senior-level capstone courses at an urban research university empirically tested a new theoretically constructed model of civic competence development in order to identify epistemological and pedagogical elements that enhance civic competence. Eight …

Toward A Taxonomy Of Diversity At Work: Developing And Validating The Workplace Diversity Inventory, Aisha Smith Taylor Jan 2011

Toward A Taxonomy Of Diversity At Work: Developing And Validating The Workplace Diversity Inventory, Aisha Smith Taylor

Dissertations and Theses

The purpose of this research was to develop a taxonomy of workplace diversity and examine its implications for understanding and predicting diversity at work. A 7-dimension taxonomy was originally developed by reviewing contemporary literature on diversity in the workplace. The taxonomy is grounded in Social Identity Theory. Preliminary research found that each of the seven dimensions of the taxonomy were present in 78 critical incidents describing work-relevant diversity dynamics. The current study reports the development and administration of an instrument, the Workplace Diversity Inventory (WDI), which was used to empirically examine the 7-factor model of the taxonomy in over 20 …

A Study Of Soil Organic Matter And Its Controlling Factors In Portland, Oregon, Megan Dillon Jan 2011

A Study Of Soil Organic Matter And Its Controlling Factors In Portland, Oregon, Megan Dillon

Dissertations and Theses

Traditionally, local above- and below-ground plant and microbial communities, temperature and precipitation, topography and texture and composition of parent material have been thought to govern the soil processes that lead to soil organic matter accumulation over decades or centuries. Soil organic matter is a substantial global reservoir of carbon and disturbance of equilibrated soils often leads to efflux of significant quantities of CO2. Anthropogenic influences shift the inputs, disturb the structure and alter the biochemistry of soil, profoundly disrupting soil-forming processes. Urbanization leads to soil organic matter equilibria that are different from those in naturally forming soils. Measurement of soil …

Perceptions And Voices Of South Sudanese About The North-South Sudan Conflict, Machar Wek Aleu-Baak Jan 2011

Perceptions And Voices Of South Sudanese About The North-South Sudan Conflict, Machar Wek Aleu-Baak

Dissertations and Theses

The conflict in Sudan reflects historic hatred and ethnic discrimination between Northern Arab Muslims and Southern African Christians and Animists. The longest and worst conflict began in 1983 and ended in 2005, when African Christians and Animists struggled to form an interim autonomous government. This conflict claimed 2 million lives from both sides and displaced almost 4 million people from the South. This thesis attempts to understand how people from Southern Sudan perceive the root causes and sustaining factors of the Sudanese conflict between Arab Muslims and African Christians. This research looks specifically into the roles of ethnic differences and …

Working In An Artist Collective In Portland Oregon: The Artistic Benefits Of Cooperation And Place In An Underground Art World, Elizabeth Furlong Borders Jan 2011

Working In An Artist Collective In Portland Oregon: The Artistic Benefits Of Cooperation And Place In An Underground Art World, Elizabeth Furlong Borders

Dissertations and Theses

This ethnography explores the underground art world in Portland, Oregon by showing how a Portland area artist collective, Oregon Painting Society, navigates their art world. Participant observation, in-depth interviews, and a short latent content analysis triangulate data to show the features and values of the underground art world. Using Becker's concept of art worlds, I show how artists working outside of a traditional art career in a commercial gallery system do their work by exploring how Portland's art world is structured and sustained. I find that group work, cooperation, and resource sharing in a vibrant neighborhood based social network enables …

The Moving To The Beat Documentary And Hip-Hop Based Curriculum Guide: Youth Reactions And Resistance, Jennifer Wallin-Ruschman Jan 2011

The Moving To The Beat Documentary And Hip-Hop Based Curriculum Guide: Youth Reactions And Resistance, Jennifer Wallin-Ruschman

Dissertations and Theses

Many of the academic and popular treatments of hip-hop overlook the complexity of the phenomenon. Hip-hop is often portrayed solely as a source of corruption and regressive tendencies or, alternatively, as a sort of savior for otherwise marginalized individuals and source of revolutionary power. This thesis situates hip-hop between these poles and draws out its progressive and regressive aspects for analysis. Considering its vast global influence and a growing body of academic literature, hip-hop has been notably understudied in the field of psychology. Alternatively, educational theorists and practitioners have realized the power of hip-hop in revisualizing an emancipatory education that …

Family-Supportive Supervisory Behaviors As A Moderator Of The Relationship Between Job Strain And Workers' Blood Pressure, Christopher Scott Harper Jan 2011

Family-Supportive Supervisory Behaviors As A Moderator Of The Relationship Between Job Strain And Workers' Blood Pressure, Christopher Scott Harper

Dissertations and Theses

Cardiovascular disease is one of the leading causes of death in industrialized nations. Research indicates that job strain may be significantly related to cardiovascular disease in employees with little to no social support. Using the JDC-S model developed by Karasek (1979) and elaborated upon by Johnson and Hall (1988), the family-supportive supervisory behaviors (FSSB) measure created by Hammer et al., (2009), and the blood pressure wrist monitor device Omron317T, this study examined FSSB as a moderator of the relationship between job strain, job demands, job control and workers' blood pressure on work and non-work days. Sixty-nine grocery store workers from …

Toward A Richer Shade Of Blue: The Impact On Oregon Police Officer Perceptions Of Racial Minorities After Anti-Racial Profiling Training, David Andrew Kline Jan 2011

Toward A Richer Shade Of Blue: The Impact On Oregon Police Officer Perceptions Of Racial Minorities After Anti-Racial Profiling Training, David Andrew Kline

Dissertations and Theses

Four fatal shootings, during police interactions, of unarmed people-of-color occurred in the Portland, Oregon Metro Area from 2003 to 2010 calling into question from members of the community whether or not the officers involved and hence their representative police departments had been racially profiling. Of interest in this study is whether or not cutting edge anti-racial profiling police officer trainings have an impact on how officers in Oregon perceive members of racial minority groups. A review of literature found that previous inquiries into racial prejudice among police officers may be present and that previous efforts to address racial ethics in …

Poverty And Conflict: A Self-Perpetuating Cycle In The Somali Regional State (Region 5), Ethiopia: 1960-2010, Bisrat Teshome Jan 2011

Poverty And Conflict: A Self-Perpetuating Cycle In The Somali Regional State (Region 5), Ethiopia: 1960-2010, Bisrat Teshome

Dissertations and Theses

Region 5 is one of the most impoverished and insecure regions of Ethiopia. For decades, the region has suffered from a multitude of armed conflicts involving state and non-state actors. Region 5 is also one of the most underserved states of Ethiopia with some of the lowest levels of human development indicators nationwide. Although the adversities of poverty and conflict are widely acknowledged in their own respect, there has been little or no inquest into why poverty and conflict have prevailed under the same space for decades. Poverty and conflict have often been seen as separate phenomena that are dealt …

Race, Ethnicity And Attitudes Toward Same-Sex Unions In The United States, Claudia Plesa Jan 2011

Race, Ethnicity And Attitudes Toward Same-Sex Unions In The United States, Claudia Plesa

Dissertations and Theses

Recent political and cultural trends have led to an evaluation of the meaning of marriage within American society, and especially marriage as it concerns couples of the same sex. However, little research has been done to find out how attitudes toward same-sex marriage might vary according to race and ethnicity. Drawing on data from the 2004 National Politics Study, the author investigates same-sex marriage attitudes and tests hypotheses concerning the attitudes of various American race-ethnic groups. This study employs multinomial logistic regression analysis to compare attitudes of African Americans, Hispanics and non-Hispanic whites. Results indicate that even when socio demographic …

Assessment Of An Optimal Bus Stop Spacing Model Using High Resolution Archived Stop-Level Data, Huan Li Jan 2011

Assessment Of An Optimal Bus Stop Spacing Model Using High Resolution Archived Stop-Level Data, Huan Li

Dissertations and Theses

In practice, the design of bus routes and stop placement involves calculated trade-offs between service frequency, quality, and access. Increased stop density improves access but contributes to slow operating speeds and increased operating costs. In this thesis, a optimized bus stop spacing model is applied using the high resolution archived stop-level bus performance data from the Bus Dispatch System (BDS) provided by TriMet, the regional transit provider for the Portland metropolitan area. Two cost components are considered in the stop spacing model including passenger access cost and in-vehicle passenger stopping cost, and are combined and optimized to minimize total cost. …

Storytelling As Loving Praxis In Critical Peace Education: A Grounded Theory Study Of Postsecondary Social Justice Educators, Amanda Smith Byron Jan 2011

Storytelling As Loving Praxis In Critical Peace Education: A Grounded Theory Study Of Postsecondary Social Justice Educators, Amanda Smith Byron

Dissertations and Theses

Looking through the philosophical lens of love, this study seeks a deeper understanding and appreciation of how postsecondary social justice educators use storytelling, in the context of critical peace education, to create social change. This research explores the guiding question of how storytelling is used to encourage social change and to inspire action toward the goal of greater social justice. The argument for the importance of this research is located within the crisis of neoliberalism, where the very tenets of democratic education are being challenged by an educational agenda that favors standards-based learning and employment training over the critical and …

Bus Replacement Modeling And The Impacts Of Budget Constraints, Fleet Cost Variability, And Market Changes On Fleet Costs And Optimal Bus Replacement Age, A Case Study, Jesse Alexander Boudart Jan 2011

Bus Replacement Modeling And The Impacts Of Budget Constraints, Fleet Cost Variability, And Market Changes On Fleet Costs And Optimal Bus Replacement Age, A Case Study, Jesse Alexander Boudart

Dissertations and Theses

Overwhelming evidence throughout the literature has shown that bus overhead and maintenance (O&M) costs increase as buses age. This has implications toward a fleet manager's decision of when one should buy, use, or sell buses to minimize total fleet costs. Unfortunately, there are uncertain market conditions associated with bus fleets that cloud the manager's ability to make appropriate decisions. Using integer programming (IP), O&M trends and changing market conditions are integrated into a model to better analyze bus fleets. Due to recent budget constraints of transit agencies, needs for a bus fleet replacement model have arisen. King County in Washington …

Social And Human Capital: Contributing Effects Of Incarceration On Neighborhoods, Jacqueline Victoria Swofford Jan 2011

Social And Human Capital: Contributing Effects Of Incarceration On Neighborhoods, Jacqueline Victoria Swofford

Dissertations and Theses

Interest in human and social capital's contribution to the desistence of crime is increasingly popular amongst criminologists, economists and policy makers. However, little attention has been drawn to the influence human and social capital indicators contribute towards the relationship between the re-entry process and juvenile crime at the neighborhood level. The current study hypothesizes the existence of a mediating relationship between human and social capital indicators (2000) and the rates of receiving formerly incarcerated persons (1997-2002) and juvenile arrest (2006-08) in 92 Portland, Oregon neighborhoods. Portland, Oregon receives more formerly incarcerated persons from Oregon's state correctional facilities than any other …

Runaway And Homeless Youth: Changing The Discourse By Legitimizing Youth Voice, Donald Dale Schweitzer Jan 2011

Runaway And Homeless Youth: Changing The Discourse By Legitimizing Youth Voice, Donald Dale Schweitzer

Dissertations and Theses

Undoubtedly, runaway and homeless youth (RHY) are one of the most vulnerable, yet underserved groups in our country. Well-meaning advocates have developed programs and services in an attempt to remedy this, yet there is little evidence of their effectiveness. Moreover, according to the research literature, a low utilization rate of current services by youth is a major concern. From a constructivist theoretical position, this study posits that the missing element is youth voice and the researcher hired formerly homeless youth to conduct the analysis of focus group data gathered from RHY who were participating in a range of services funded …

Self-Efficacy And Drinking With Friends: An Investigation Into The Drinking Behaviors Of Japanese College Students, Staci Jean Wendt Jan 2011

Self-Efficacy And Drinking With Friends: An Investigation Into The Drinking Behaviors Of Japanese College Students, Staci Jean Wendt

Dissertations and Theses

Recent studies have documented an alarming rate of alcohol use in Japan (Eisenback-Stangl et al., 2005; Milne, 2003; Shimizu, 2000). Indeed, permissive social and cultural norms for alcohol use exist within Japanese culture (Shimizu, 1990, 2000). Japanese college-students may be at further risk due to their developmental time period, where increases in alcohol use are typically seen. Furthermore, drinking habits formed during this time period may be difficult to alter later in life (Frone, 2003). Thus, social, developmental, and cultural factors exist to influence drinking among Japanese college students. The purpose of the current study was to investigate the drinking …

Writing Her Way To Spiritual Perfection: The Diary Of 1751 Of Maria De Jesus Felipa, Stephanie Oliver Jan 2011

Writing Her Way To Spiritual Perfection: The Diary Of 1751 Of Maria De Jesus Felipa, Stephanie Oliver

Dissertations and Theses

Throughout the colonial period of Mexican history, cloistered nuns wrote spiritual journals at the request of their confessors. These documents were read and scrutinized, not only by the confessors, but also by others in the hierarchy of their Orders. They are important sources of study for historians in that they provide a window into the religious culture of the times and the spiritual mentality of their authors. This thesis will examine one such record, discovered in a collection of volumes at the Historical Franciscan Archive of Michoacán in Celaya, Mexico. The diary covers eleven months of 1751 in the life …
