Relational Aggression Among Caucasian And Northern Plains American Indian School Children, Stephanie Parisien

Theses and Dissertations

Relational aggression is a form of aggression that has received increasing attention within the psychological literature. Among the American Indian population, however, research on relational aggression is currently non-existent. To date, research is continuing to grow with regard to the base rates of relational aggression. The current study has examined both peer-nominated and self-report relational aggression among Caucasian and Northern Plains American Indian school children in order to explore cultural, gender, grade level, and age differences. Other forms of aggression and social status were also explored in order to understand how these constructs may play a role in peer relations. …

Novel Sustainable Structural Materials By Using Benign Waste Materials, M Faisal Riyad

Theses and Dissertations

We propose a Green Cement Paradigm (GCPa) for fabricating environmentally friendly cementitious materials. By using GCPa, we report for the first time, the usage of Class C Fly Ash as a sole source of cementitous phase without any activation by alkali. During this study, Class C Fly Ash, and its composites with sand were fabricated at different compaction stresses by maintaining a low w/c (w-water, c-cement) ratio of 0.17-0.24 in the compacts. The porosity and the number of days for curing played a significant role in the evolution of compressive strength. The experimental results indicate that the curing for 28 …

Investigation Of Marine Stratocumulus Under Coupled And Decoupled Conditions Over The Arm Azores Site, Adam Christopher Schwantes

Theses and Dissertations

Stratocumuli are a type of low clouds composed of individual convective elements that together form a continuous layer of clouds. Stratocumuli cover large regions of the Earth's surface, which make them important components in the Earth's radiation budget. Stratocumuli strongly reflect solar shortwave radiation, while weakly affecting outgoing longwave radiation. This leads to a strong radiative cooling effect that affects the Earth's radiation budget. Therefore it is important to investigate the mechanisms that affect the longevity of stratocumuli, so that their impact on the Earth's radiation budget can be fully understood. One mechanism that is currently being studied as influencing …

The first article defines Sci-YAR and argues for its potential to enhance youth's participation as citizens in a democratic society. The second article details findings from a case study of youth engaged in Sci-YAR, describing how the curriculum enabled and constrained youth's identity …

Eq, Not Just Iq: The Relationship Between Emotional Intelligence And The Success Of High School Principals Who Have Been Awarded The Illinois Principals Association's High School Principal Of The Year Award, Rowena Mak

Dissertations

As educational reforms become more complex, the role of the principal as a change agent also becomes more challenging and dynamic. To confront the leadership demands of schools, principals require focus, passion, wisdom, courage, and integrity.

An underlying assumption of these traits is the principal's emotional fortitude. Emotional intelligence is as complicated as it is organic, in that its foundation rests on an individual's awareness of himself/herself and how these emotions drive his/her ability to relate with others. With this comes the question, what makes a successful principal? The purpose of this research was to explore the relationship between a …

Corporate Taxation And Corporate Social Responsibility, Reuven S. Avi-Yonah

Articles

This Article will address the question of whether publicly traded U.S. corporations owe a duty to their shareholders to minimize their corporate tax burden through any legal means, or if instead, strategic behaviors like aggressive tax-motivated transactions are inconsistent with corporate social responsibility (“CSR”). I believe the latter holds true, regardless of one’s view of the corporation. Under the “artificial entity” view, such behavior undermines the constitutive relationship between the corporation and the state. Under the “real view,” such behavior runs contrary to the normal obligation of citizens to comply with the law (even absent effective enforcement). And under the …

Interdisciplinary Perspectives On Corruption, David Jancsics

Publications and Research

Corruption has become one of the most popular topics in the social scientific disciplines. However, there is a lack of interdisciplinary communication about corruption. Models developed by different academic disciplines are often isolated from each other. The purpose of this paper is to review several major approaches to corruption and draw them closer to each other. Most studies of corruption fall into three major categories: (i) rational-actor models where corruption is viewed as resulting from cost/benefit analysis of individual actors; (ii) structural models that focus on external forces that determine corruption; and (iii) relational models that emphasize social interactions and …

Variance Predicts Salience In Central Sensory Processing, Ann M. Hermundstad, John J. Briguglio, Mary M. Conte, Jonathan D. Victor, Vijay Balasubramanian, Gašper Tkačik

Publications and Research

Information processing in the sensory periphery is shaped by natural stimulus statistics. In the periphery, a transmission bottleneck constrains performance; thus efficient coding implies that natural signal components with a predictably wider range should be compressed. In a different regime—when sampling limitations constrain performance—efficient coding implies that more resources should be allocated to informative features that are more variable. We propose that this regime is relevant for sensory cortex when it extracts complex features from limited numbers of sensory samples. To test this prediction, we use central visual processing as a model: we show that visual sensitivity for local multi-point …

Idiots Savants, Retarded Savants, Talented Aments, Mono-Savants, Autistic Savants, Just Plain Savants, People With Savant Syndrome, And Autistic People Who Are Good At Things: A View From Disability Studies, Joseph N. Straus

Publications and Research

People identified as idiot savants have long comprised an identifiable group (a high level of skill in the context of perceived mental deficiency) whose story has mostly been told by psychiatrists and psychologists within a medicalized model of disability that assumes deficiency and seeks remediation and normalization. More recently, people identified as savants have become common figures of literary and cinematic representation. Both of these narrative frames have enfreaked them as alien Others, whose gifts and disabilities place them outside the normal run of human intelligence and creativity. With a focus on music, this article tries to see through these …

Buenos Aires, Fernando Degiovanni, Fernando Rosenberg

Publications and Research

One of the most important city ports of the Western Hemisphere, Buenos Aires has a history inextricably connected to the fluctuations of the Atlantic economy as well as to its strategic position as a gateway to vast and fertile flatlands that extend far beyond the city limits. Founded and re-founded in the 16th century as a secondary colonial outpost, Buenos Aires was dramatically transformed by the demands of the European markets at the turn of both the 18th and 19th centuries. In this context, two crucial developments are decisive for understanding the physical, social, and cultural fabric of the city: …

The Appeal Of Narrative In Research, Colette Daiute

Publications and Research

"I saw the bird flattened on the ground outside my door . One of the kindergarten child walked toward me slowly, crying. That's when I knew it was time to act."

The very brief narrative above occurs amid myriad spheres of social relations. These relations are not all apparent, but understanding narrative meaning requires understanding narrating as an interactive process. As researchers we enhance our Methods if we know how to read narratives as complex social processes. This openi11g narrative expresses a sequence of two past events.1 The narrative involves action ("walked," "act") and consciousness ("saw," "crying," "knew"). From the …

An Atrial Activity Based Algorithm For The Single-Beat Rate-Independent Detection Of Atrial Fibrillation, Steven J. Ladavich Jr.

Theses

Atrial fibrillation (AF) is the most common cardiac arrhythmia and is the cause of 15% of all ischemic strokes in the United States. In many cases, AF is episodic and/or asymptomatic and as a result, there is a strong need for algorithms capable of quickly and reliably detecting AF, even in cases where the heart rate is controlled through medication or with a pacemaker. Current RR interval (RRI)-based algorithms do not directly target atrial activity, cannot detect AF when the heart rate is controlled, and analyze relatively long intervals of the electrocardiography (ECG) to make an AF determination. This work …

Server-Based Desktop Virtualization, Anas Raqi Shabaitah

Theses

Virtualization can be accomplished at different layers in the computational stack and with different goals (servers, desktops, applications, storage and network). This research focuses on server-based desktop virtualization. According to the Gartner group, the main business drivers for adopting desktop virtualization are: application compatibility, business continuity, security and compliance, mobility and improved productivity [15]. Despite these business drivers, desktop virtualization has not been widely adopted. According to a survey conducted by Matrix42, only 5% of desktop computers are virtualized [37]. The research deals with the challenges preventing the wider adoption of server-based desktop virtualization while focusing on two of the …

Design Trade-Offs For Reliable On-Chip Wireless Interconnects In Noc Platforms, Manoj Prashanth Yuvaraj

Theses

The massive levels of integration following Moore's Law making modern multi-core chips prevail in various domains ranging from scientific applications to bioinformatics applications for consumer electronics. With higher and higher number of cores on the same die traditional bus based interconnections are no longer a scalable communication infrastructure. On-chip networks were proposed enabled a scalable plug-and-play mechanism for interconnecting hundreds of cores on the same chip. Wired interconnects between the cores in a traditional Network-on-Chip (NoC) system, becomes a bottleneck with increase in the number of cores thereby increasing the latency and energy to transmit signals over them. Hence, there …

Antenna Gain Enhancement And Beamshaping Using A Diffractive Optical Element (Doe) Lens, Christopher Torbitt

Theses

Dielectric and metamaterial lenses have been designed for gain enhancement and beam shaping. The motivation for this work came from a commercially available slotted waveguide antenna with a dielectric lens that shapes the beam and enhances the gain only in the azimuth plane. When two of these antennas, each with a dielectric lens, are stacked as an array to form the sum and difference patterns the elevation plane gain is low and the beam width too wide to be acceptable for radar applications.

The objective of the present work is to design a diffractive optical element (DOE) lens for gain …

Variability In The Phenolic Content Of Invasive And Non-Invasive Emergent Wetland Plants, Melissa M. Maurer

Theses

The colonization of wetlands by invasive plant species negatively impacts vegetation structure, nutrient and organic matter cycling, and ultimately alters native wetland ecosystem functions and services. It is unclear if the spread of invasive species can be attributed to their chemical composition. To further understand mechanisms of plant invasion, it is important to assess secondary chemistry of aggressive invaders. Phenolic compounds are important due to their diverse functionality including pathogen resistance, herbivore deterrence, and allelopathic interference. I conducted a broad field survey and a field experiment to better understand the importance and variability of wetland plant phenolic compounds and the …

A New Covert Channel Over Cellular Network Voice Channel, Bushra Sulaiman Aloraini

Theses

Smartphone security has become increasingly more significant as smartphones become a more important part of many individuals' daily lives. Smartphones undergo all computer security issues; however, they also introduce a new set of security issues as various capabilities are added. Smartphone security researchers pay more attention to security issues inherited from the traditional computer security field than smartphone-related security issues. The primary network that smartphones are connected to is the cellular network, but little effort has been directed at investigating the potential security issues that could threaten this network and its end users.

A new possible threat that could occur …

American Indian populations experience high rates of psychological distress with 44.5% percent of Northern Plains American Indians reporting experiencing some depressive, anxiety, or substance use disorder over their lifetime. The MMPI-2 is a commonly used psychodiagnostic tool that has become widely used in the mental health treatment of different racial and ethnic groups. Research on the MMPI-2 with minority populations, and American Indian populations in particular, fails to account for the impact of level of acculturation. This study examined the impact of cultural identity on MMPI-2 profiles in Northern Plains American Indians and comparison Caucasian samples. Participants were administered a …

Depression, Negative Self-Disclosure, And The Response Of Others On Facebook, Daniel Barrett Landauer

Theses and Dissertations

Depression has a number of deleterious effects on the interpersonal functioning of adolescents and emerging adults. The interpersonal theory of depression posits that depression is developed and maintained by both the behaviors of the individual and the responses of others to the individual. Adolescents and emerging adults are spending a significant amount of time interacting on social networking sites, such as Facebook, yet few studies have looked at the interpersonal behavior of depressed youth in the context of the interpersonal theory of depression. This study examined the interpersonal behavior of 328 emerging adult college students on Facebook using questionnaires related …

Effect Of Bronsted And Lewis Acids On Biochemical Conversion Of Various Lignocellulosic Feedstocks Into Biofuels And Chemicals, Srinivas Reddy Kamireddy

Theses and Dissertations

A biochemical process was investigated in the conversion of lignocellulosic biomass into biofuels and value added chemicals. Kenaf, two species of sorghum (brown mid rib (BMR) & non brown mid rib (NBMR)), sunn hemp, sunflower hulls, and cornstover were used as feedstocks in this study.

Lignocellulosic biomass primarily consists of three different components, cellulose, hemicellulose and lignin. In order to separate different fractions, and acid pretreatment is generally employed. This was achieved by using a 300 ml internal volume batch reactor. The heating source used was steam. During acid pretreatment most of the hemicellulose is hydrolyzed into the liquid fraction. …
