Performance And Energy Efficiency Of Common Compression/Decompression Utilities : An Experimental Study In Mobile And Workstation Computer Platforms, Armen A. Dzhagaryan

Theses

Lossless compression and decompression are routinely used in mobile and workstation computer systems to reduce the costs of communicating and storing data. This research presents the results of a measurement-based experimental evaluation of common compression and decompression utilities running on several plat-forms of varying hardware complexity representing current mobile and workstation systems. The evaluation involves characterization of the compression and decompression utilities in a multidimensional space encompassing the compression ratio, compression and decompression throughput, and energy efficiency. Different use scenarios and conditioning typical for modern mobile and workstation computing platforms are considered. The study observes a wide variety of energy …

Generation Of Radio Frequency Induced Metastable Xenon As A Gain Medium For Diode Pumped Rare Gas Laser Systems, Jacqueline Marie Andreozzi

Theses

The pursuit of novel, hybrid methods of achieving lasing from the rare gases has recently been a topic of interest in the field of high energy laser systems. This investigation presents the construction and execution of an experimental setup designed to generate metastable xenon (Xe*) to determine its potential to perform as a high power laser gain medium in a similar capacity as the alkali metals in Diode Pumped Alkali Lasers. A capacitively coupled radio frequency discharge was used to light plasma from naturally abundant xenon, thus exciting the 6s[3/2]₂ metastable state. The metastable xenon was probed with a …

How Strong Are The Effects Of Technological Disruption? Smartphones' Impacts On Internet And Cable Tv Services Consumption, M. R. Chang, Robert J. Kauffman, K.S. Kim

Research Collection School Of Computing and Information Systems

Emerging technologies have created disruptions in organizational, business process and industry contexts. They act as shocks to a system. We focus on a retail telecom service provider’s offerings of different bun-dles, including mobile phones, Internet and cable TV services. We conduct empirical regularities analysis for Singapore, which was affected by the emergence of smartphones in 2009. We assess the impacts on the service bundle choices of a provider’s customers. We analyze customer switching among service bundles involving three services. We compute switching proba-bilities for each of the service levels offered, as well as between bundles. We use Markov chain transition …

Multimedia Recommendation: Technology And Techniques, Jialie Shen, Meng Wang, Shuicheng Yan, Peng Cui

Research Collection School Of Computing and Information Systems

In recent years, we have witnessed a rapid growth in the availability of digital multimedia on various application platforms and domains. Consequently, the problem of information overload has become more and more serious. In order to tackle the challenge, various multimedia recommendation technologies have been developed by different research communities (e.g., multimedia systems, information retrieval, machine learning and computer version). Meanwhile, many commercial web systems (e.g., Flick, YouTube, and Last.fm) have successfully applied recommendation techniques to provide users personalized content and services in a convenient and flexible way. When looking back, the information retrieval (IR) community has a long history …

Saving The First Amendment From Itself: Relief From The Sherman Act Against The Rabbinic Cartels, Barak D. Richman

Faculty Scholarship

America’s rabbis currently structure their employment market with rules that flagrantly violate the Sherman Act. The consequences of these rules, in addition to the predictable economic outcomes of inflated wages for rabbis and restricted consumer freedoms for the congregations that employ them, meaningfully hinder Jewish communities from seeking their preferred spiritual leader. Although the First Amendment cannot combat against this privately-orchestrated (yet paradigmatic) restriction on religious expression, the Sherman Act can. Ironically, however, the rabbinic organizations implementing the restrictive policies claim that the First Amendment immunizes them from Sherman Act scrutiny, thereby claiming the First Amendment empowers them to do …

Mapping A Post-Shelby County Contingency Strategy, Guy-Uriel Charles, Luis Fuentes-Rohwer

Faculty Scholarship

This Essay was written for the Yale Law Journal Online Symposium on the future of section 5 of the Voting Rights Act after Shelby County v. Holder. Professors Guy-Uriel E. Charles and Luis Fuentes-Rohwer argue that voting rights activists ought to be prepared for a future in which section 5 is not part of the landscape. If the Court strikes down section 5, an emerging ecosystem of private entities and organized interest groups of various stripes—what they call institutional intermediaries—may be willing and able to mimic the elements that made section 5 an effective regulatory device. As voting rights …

In The Absence Of Scrutiny: Narratives Of Probable Cause, Mitu Gulati, Jack Knight, David F. Levi

Faculty Scholarship

This Article reports on a set of roughly thirty interviews with federal magistrate judges. The focus of the interviews was the impact of the Supreme Court case, United States v. Leon, on the behavior of magistrate judges. Leon, famously, put in place the "good faith" exception for faulty warrants that were obtained by the officers in good faith. The insertion of this exception diminished significantly the incentive for defendants to challenge problematic warrant grants. That effect, in turn, could have diminished the incentive for magistrate judge scrutiny of the warrants at the front end of the process. We do not …

Biometric Id Cybersurveillance, Margaret Hu

Faculty Scholarship

The implementation of a universal digitalized biometric ID system risks normalizing and integrating mass cybersurveillance into the daily lives of ordinary citizens. ID documents such as driver’s licenses in some states and all U.S. passports are now implanted with radio frequency identification (RFID) technology. In recent proposals, Congress has considered implementing a digitalized biometric identification card—such as a biometric-based, “high-tech” Social Security Card—which may eventually lead to the development of a universal multimodal biometric database (e.g., the collection of the digital photos, fingerprints, iris scans, and/or DNA of all citizens and noncitizens). Such “hightech” IDs, once merged with GPS-RFID tracking …

The Unraveling Of The Private Consensus, Justin Kh Tse

Research Collection School of Social Sciences

The Asian American Open Letter to the Evangelical Church was a key moment in the unraveling of the private consensus in American evangelicalism in 2013. What I call the “private consensus” is an implied agreement among evangelical Protestants in America that churches, parachurch organizations, and religious institutions should conduct matters privately. In fact, it might go as far as to say that individual Christians should act in private, away from the public eye, especially the media. When Christian matters become public, so the argument goes, they become distorted. Consequently, Christians are encouraged to operate at a “direct and personal” level, …

Mapping Dissent: The Responsibility To Protect And Its State Critics, Patrick Quinton-Brown

Research Collection School of Social Sciences

Addressing dissent, also known as ‘rejectionism’, will broaden and deepen the global consensus on the Responsibility to Protect (R2P) principle. However, how should scholars understand the objections raised by state critics? To answer this question, I analyse R2P opposition as presented in official UN transcripts, voting records, and resolutions. The article reveals that six related themes of dissent exist with varying degrees of emphasis amongst opponents. Conventional depictions of R2P opposition, such as the absolute sovereignty or North vs. South explanations, are therefore inadequate representations of the diverse range of arguments employed by dissenters. Ultimately, I conclude that in order …

Measuring Differentials In Communication Research: Issues With Multicollinearity In Three Methods, Sonny Rosenthal

Research Collection College of Integrative Studies

Models of communication processes sometimes require the computation of the difference between two variables. For example, information insufficiency is the difference between what people know and what they think they need to know about an issue, and it can motivate information seeking and processing. Common methods that compute this differential may bias model estimates as a function of the correlation between the differentiated variables and other variables in the model. This article describes Citation the general form of Cohen and Cohen's (1983) analysis of partial variance for computing differentials and analyzes simulated data to contrast that method with two alternative …

Secularity, Religion And The Possibilities For Religious Citizenship, Lyn Parker, Chang Yau Hoon

Research Collection School of Social Sciences

Scholarly predictions of the secularization of the world have proven premature. We see a heterogeneous world in which religion remains a significant and vital social and political force. This paper reflects critically upon secularization theory in order to see how scholars can productively respond to the, at least partly, religious condition of the world at the beginning of the twenty first century. We note that conventional multiculturalism theory and policy neglects religion, and argue the need for a reconceptualization of understanding of religion and secularity, particularly in a context of multicultural citizenship — such as in Australia and Indonesia. We …

Correlates Of Bullying Behaviors Among A Sample Of North American Indigenous Adolescents, Lisa A. Melander, Kelley J. Sittner Hartshorn, Les B. Whitbeck

Department of Sociology: Faculty Publications

The purpose of this study was to examine the relationship between familial, educational, and psychosocial factors and bullying among 702 North American Indigenous adolescents aged 11–14 years. The study used multinomial logistic regression models to differentiate correlates of bully perpetration and victimization versus being neither and between being a perpetrator versus being a victim. Analyses reveal that being a bully victim had different correlates than being a perpetrator. Perceived discrimination was associated with increased odds of being either a victim or a perpetrator, relative to being neither. Several factors differentiated being a bully perpetrator from being a bully victim: adolescent …

Casting Minority Gifted Students: The Pedagogical Impact Of Cinema On The Culture Of Schooling, Deborah F. Burnette

College of Graduate Studies: Theses & Dissertations

African American students are significantly underrepresented in gifted education programs. This dissertation creates a space where gifted education, African American students, media literacy, and teacher perceptions intersect in the field of curriculum studies. Media literacy will be utilized to critique popular films by gifted endorsement teacher-students and myself. Due to the low number of states that require pre-service teachers to study gifted characteristics of children it is left up to gifted teacher endorsement programs to train teachers. By using media literacy to examine films in gifted teacher endorsement programs, I assert that the under-representation of African American students in the …

From College Student To Change Agent: A Triadic Model Of Self-Efficacy, Attribution, And Appraisal, Joshua M. Garrin

Journal of Sustainable Social Impact

Beyond their newfound emancipation and opportunities for self-discovery, college students in the young adult stage of development are expected to achieve balance between their autonomous new world and the impending pressures of postgraduation life. The college student must not only reconcile issues related to identity formation, goal pursuits, and career exploration, but is expected to begin the process of identifying and developing the skills required to address salient social themes. How students establish competency beliefs, negotiate controllability over future outcomes, and appraise challenges have deep implications in their capacity to discover their social change “voice.” The following discussion proposes a …

Paradata For Nonresponse Adjustment, Kristen Olson

Department of Sociology: Faculty Publications

Survey researchers and practitioners use nonresponse adjustment weights to mitigate the effects of survey nonresponse on sample estimates. One challenge in creating these weights is finding useful auxiliary data that predict both the probability of participating in the survey and the survey variables of interest. This article reviews the use of paradata for nonresponse adjustment. Five different types of paradata are considered: neighborhood observations, observations of the sampled housing unit, observations of persons in the sampled housing unit, call records, and observations about the interviewer-householder interaction. Empirical evidence about the predictive value of these paradata for predicting both participation and …

Engaging Teenagers With Science Through Comics, Amy N. Spiegel, Julia Mcquillan, Peter Halpin, Camillia Matuk, Judy Diamond

Department of Sociology: Faculty Publications

It is increasingly important for all citizens, and especially youth, to understand how viruses impact our health, communities and environment. Particularly for youth less interested in traditional science learning materials, comics may provide a way to engage teenagers with scientific information about viruses. We compared the impacts of different formats of educational materials on teenagers’ knowledge of, attitudes toward, and engagement with information about viruses. High school students (N = 873) were randomly assigned to read either a high quality comic or essay about viruses. Latent class analysis grouped youth into one of four categories that captured a range from …

The Limits Of Violence: People And Property In Edward Abbey's "Monkeywrenching" Novels, David Thomas Sumner

Faculty Publications

This paper explores Edward Abbey’s fiction asking what kind of ethical imperative his monkeywrenching novels offer. While advocating the destruction of property in defense of wilderness, The Monkey Wrench Gang draws a clear ethical distinction between the destruction of property in defense of wilderness and the harming of people. Yet the sequel, Hayduke Lives!, blurs this ethical line when a security guard is killed during the novel’s final eco-sabotage scene. After exploring several possible textual explanations for this apparent change and then interviewing several of Abbey’s close friends regarding this issue, the author concludes that the shift does not …

The Broken Safety Net: A Study Of Earned Income Tax Credit Recipients And A Proposal For Repair, Sara Sternberg Greene

Faculty Scholarship

The Earned Income Tax Credit (EITC) is the largest federal antipoverty program in the United States and garners almost universal bipartisan support from politicians, legal scholars, and other commentators. However, assessments of the EITC missed an imperative perspective: that of EITC recipients themselves. Past work relies on largely unconfirmed assumptions about the behaviors and needs of low-income families. This Article provides a novel assessment of the EITC based on original data obtained directly from 194 EITC recipients through in-depth qualitative interviews. The findings are troubling: They show that while the EITC has important advantages over welfare, which it has largely …

The Construction Of Local Road Safety Issues: When Lay And Professional Discourses Collide, Stephen Ball

Plymouth Business School Theses

Highway Authorities in the United Kingdom have jurisdiction to control, maintain and improve the local highway network, and the Road Traffic Act 1988 places a duty on such authorities to take preventative measures to reduce road casualties. As such, engineers working for the Highway Authority are on the ‘front-line,’ and are required to deal directly with lay concerns relating to road safety. This study investigates the nature and characteristics of how local road safety issues are raised and how engineers respond to such issues in a local authority setting. A grounded theory methodology was applied in the collection and analysis …

Election Data Visualisation, Elena Long

Plymouth Business School Theses

Visualisations of election data produced by the mass media, other organisations and even individuals are becoming increasingly available across a wide variety of platforms and in many different forms. As more data become available digitally and as improvements to computer hardware and software are made, these visualisations have become more ambitious in scope and more user-friendly. Research has shown that visualising data is an extremely powerful method of communicating information to specialists and non-specialists alike. This amounts to a democratisation of access to political and electoral data. To some extent political science lags behind the progress that has been made …

The Effect Of Sex And Gender Role Orientation On Attitudes Towards Individuals With Dependent Personality Disorder, Amanda K. Slowik

All-Inclusive List of Electronic Theses and Dissertations

Research suggests that Dependent Personality Disorder (DPD) is associated with a feminine gender role and the female sex. However, little is known about how men who demonstrate DPD are perceived. Research also suggests that attitudes might be affected by the sex and gender role of the participant, with men and individuals who identify with traditional gender roles making harsher judgments of individuals who exhibit behaviors that are not consistent with traditional gender roles. As the categorical diagnosis of personality disorders has been widely criticized and may soon be replaced, the DSM-5 draft describes the symptoms of DPD using three dimensions …

The Effects Of Processing Fluency On Restorative Environments, Andrea Ahles

All-Inclusive List of Electronic Theses and Dissertations

Attention Restoration Theory (ART) maintains that directed attention, a type of attention that requires effort, is a resource that is susceptible to fatigue after prolonged use. This directed attention fatigue, commonly known as mental fatigue, is a factor linked to performance and safety decline in the workplace. Many studies have found that contact with nature promotes restoration from directed attention fatigue; however, there is little research on how nature has this effect. The aim of the present study was to explore whether natural environments have restorative potential given their higher degree of processing fluency. College students ( N =78) were …

White Trash, Heather Law

Theses

White Trash, is body of work that aims to reflect upon our personal role and contribution to the solid waste stream through routine consumption and waste disposal. From everything we eat and drink, to the refuse we flush down the drain, we all consume resources. Living in a materially saturated, mass-consumer society, we have evolved into an increasingly disposable culture. By identifying with our waste production, we then can better evaluate the pitfalls of our materialistic ways. Common consumer products stuffed inside a toilet creates a recognizable waste pattern found within the domestic household. Our trash is considered pollution. Once …

Determination Of Pb(Ii) In Natural Water With Dibromo-P-Methyl-Sulfonazo By The Light-Absorption Ratio Variation Approach, Jie Zhang

Turkish Journal of Chemistry

Pb ions can react sensitively with dibromo-p-methylsulfonazo (DMSA) to form a blue complex, whose absorption is maximal at 630 nm. By means of the light-absorption ratio variation approach (LARVA), the direct determination of Pb was developed in 0.3 M nitric acid and plots of \Delta A_r^{-1} vs. c_{Pb}^{-1} are linear where \Delta A_r is the light-absorption ratio variation and c_{Pb} Pb(II) concentration is between 0 and 5.0 mg/L. The limit of detection (3\sigma) of Pb(II) is only 0.02 mg/L. This method was applied to direct analysis of natural water with satisfactory results.

Music Cultures Of Mechanical Reproduction, Peter L. Manuel

Publications and Research

Popular musics arc best understood as comprising those genres whose styles have evolved in an inextricable relation with their dissemination via the mass media and their marketing and sale on a mass-commodity basis. While much popular-music activity takes place independently of the mass media, other essential aspects of popular-music production and marketing arc inevitably inseparable from technologies of mechanical reproduction, which perforce condition aspects of music culture in general. Hence, just as one could speak of military cultures based around the stirrup, or later the firearm, or agrarian cultures based on the hoe, the ox, or the tractor, so do …
