Adolescent Victims' Experiences With Cyberbullying: A Grounded Theory Study, Melvina S. Brandau

Theses and Dissertations

The purpose of this study was to construct a Grounded Theory that explains the processes involved in cyberbullying from the perspectives of those who have been victimized. A Constructivist Grounded Theory approach was used to explain the processes that occur as cyberbullying begins, unfolds, and ends, as well as to determine the methods that adolescent victims use to cope, and the context in which cyberbullying occurs.

Cyberbullying is a pervasive public health issue, affecting an estimated 10-30% of youth. Cyberbullying, though closely related to traditional physical bullying, has qualities that make it distinctive. Unlike traditional bullying, cyberbullying is relatively new …

Identification And Characterization Of A Putative Populus E3 Ring-H2 Ubiquitin Ligase That When Over-Expressed Is Correlated With Insect Resistance To Orgyia Leucostigma, Justin Burum

Theses and Dissertations

Insect herbivory is a major stress on plants that results in significant economic losses to forest plantations and natural forests. In response, Populus have evolved a suite of constitutive and inducible defenses to deter insect feeding. Despite advances in technologies and the sequencing of the Populus trichocarpa genome, defensive pathways against insect herbivores are poorly understood. With the creation of activation tagged (AT) Populus we can use a forward genetics approach to identify genes involved in insect resistance (IR). To explore the genetic architecture of tree defenses, we conducted a forward genetics screen of AT Populus tremula x Populus alba …

The Effect Of Pulsed Flow On The Heat Transfer Coefficient Of A Vertical Tube Suspended In A Fast Fluidized Bed, Tyler Curran

Theses and Dissertations

An experimental study was conducted to determine the effects of pulsing the fluidizing air on the heat transfer of a small vertical cylindrical heater suspended along the axis of a 101.9 mm diameter fast bed. Spherical aluminum metal power with a density of 2700 kg/m3 and dp50 of 107 μm was used in this investigation. Experiments were first conducted without pulsing the air supply. Solids fractions were observed as high as .0154 with superficial velocities from 1.98 m/s to 4.04 m/s and recirculation rates up to 27.6 kg/m2 s. The maximum heat transfer observed was 74.1 W/m2 K at a …

Trash Matters: An Investigation Into The Current Waste Management And Recycling Strategies In Rural North Dakota And Foreseeable Solutions, Amy Densborn

Theses and Dissertations

Rural North Dakota is behind the times for establishing an economically and socially beneficial method for collecting recyclables from residents, and in some areas providing sustainable trash removal. As the waste stream continues to grow, so will the burdens on our landfills, our resources and our environment for generations to come. An even worse alternative to landfilling garbage is the use of burn barrels, which release dioxins into the local environment, settling on vegetation and waterways and further bio-accumulate in the food chain. Rural residents currently do not have conveniently located or affordable disposal options for household generated waste and …

Labeling Of Religious Non-Believers: The Effect Of The "Atheist" Title On Moral Judgments About Non-Theists, Brock C. Rozich

Dissertations and Theses @ UNI

Prior research indicates that how concepts are described impacts our beliefs about the subject itself. For example, when the term “welfare” (instead of “help for the poor”) is used to ask people whether assistance should be increased in times of economic hardship, support is lower (Smith, 1987). My research question centers on whether or not this effect would carry over to the area of religion and the use of the terms “atheist” or “those with no religious beliefs.” Participants in the current studies were presented with a vignette about a student who was labeled as an atheist, as having no …

Dying To Live Forever Sophia Harris Journal 1860 To 1861, Shirley Ilene Davis

Dissertations and Theses @ UNI

Sophia Harris’s journal is a window into one woman’s experiences in an area that transformed from a frontier outpost to a market-oriented and increasingly urbanized society. It also sheds light on how she made sense of the meaning of these changes in her personal life: specifically how her religious understandings of death shaped her understanding of the world she lived in.

"Rock Against Reagan": The Punk Movement, Cultural Hegemony, And Reaganism In The Eighties, Johnathan Kyle Williams

Dissertations and Theses @ UNI

Despite scholars’ growing interest in the cultural movement known as punk, there has been a lack of focus on the movement’s relationship to its historical context. Punk meant rebellion, and this research looks at how the rebellion of the American punk movement during the eighties [1978 to 1992], was aimed at the president Ronald Reagan. Their dissent, however, was not only directed towards Reagan, but the culture that he encompassed. Under this influence, American culture gave way to Reaganism: a culture of individualism, greed, power, and symbols. Adding to the work by historian Dewar MacLeod and others who have focused …

Spest – A Tool For Specification-Based Testing, Corrigan Redford Johnson

Master's Theses

This thesis presents a tool for SPEcification based teSTing (SPEST). SPEST is designed to use well known practices for automated black-box testing to reduce the burden of testing on developers. The tool uses a simple formal specification language to generate highly-readable unit tests that embody best practices for thorough software testing. Because the specification language used to generate the assertions about the code can be compiled, it can also be used to ensure that documentation describing the code is maintained during development and refactoring.

The utility and effectiveness of SPEST were validated through several exper- iments conducted with students in …

Sexual assault is a complex problem, and there is no set of best practices for sexual assault prevention and education programs. Social norms marketing and expectancy violations, however, have been proposed to be influential factors that may aid in increasing prosocial attitudes related to sexual assault. Therefore, the purpose of this study was to evaluate the potential effect of social norm feedback and expectancy violations on attitudes related to sexual assault and bystander intervention. Participants in the study included 244 undergraduate and graduate students who completed an experiment embedded in an online survey. Results indicated that there were no significant …

The Effects Of Construal Level On Stigmatizing Attitudes Toward An Individual With Mental Illness, Jeremy Glenn Gay

Electronic Theses and Dissertations

People with mental illness often face stigmatization by society. However, little research has examined cognitive factors that may activate or dissipate stigmatizing attitudes toward those with mental illness. Construal level, or the extent that people focus on abstract generalizations versus concrete details of events, may be one such cognitive factor. Two contradictory hypotheses emerged concerning how construal may affect stigmatizing attitudes. One hypothesis suggests that abstract construals will decrease stigmatization because abstract construals tend to increase the activation of similar goals, thus leading to a similarity focus. In contrast, another hypothesis suggests that abstract construals will increase stigmatization because abstract …

Design, Analysis, Implementation And Evaluation Of Real-Time Opportunistic Spectrum Access In Cloud-Based Cognitive Radio Networks, Nimish Sharma

Electronic Theses and Dissertations

Opportunistic spectrum access in cognitive radio network is proposed for remediation of spectrum under-utilization caused by exclusive licensing for service providers that are intermittently utilizing spectrum at any given geolocation and time. The unlicensed secondary users (SUs) rely on opportunistic spectrum access to maximize spectrum utilization by sensing/identifying the idle bands without causing harmful interference to licensed primary users (PUs). In this thesis, Real-time Opportunistic Spectrum Access in Cloud-based Cognitive Radio Networks (ROAR) architecture is presented where cloud computing is used for processing and storage of idle channels. Software-defined radios (SDRs) are used as SUs and PUs that identify, report, …

Performance Analysis Of Secondary Users In Heterogeneous Cognitive Radio Network, Tanjil Amin

Electronic Theses and Dissertations

Continuous increase in wireless subscriptions and static allocation of wireless frequency bands to the primary users (PUs) are fueling the radio frequency (RF) shortage problem. Cognitive radio network (CRN) is regarded as a solution to this problem as it utilizes the scarce RF in an opportunisticmanner to increase the spectrumefficiency. InCRN, secondary users (SUs) are allowed to access idle frequency bands opportunistically without causing harmful interference to the PUs. In CRN, the SUs determine the presence of PUs through spectrum sensing and access idle bands by means of dynamic spectrum access. Spectrum sensing techniques available in the literature do not …

Zoetic Fitness, Brooke S. Fremeau

Electronic Theses and Dissertations

Graphic design is a problem-solving field. A client or company tasks a designer with a problem, and to solve that problem the designer uses 2D fundamentals and technology. As a designer, one must carefully listen to the client to understand their needs before making design decisions. While graphic designers are responsible for creating stunning visuals for both print and digital media, one of the most important aspects of graphic design is branding. Broadly speaking, branding is the process involved in creating a unique name and image for a product or service in a consumers mind. Through branding, the designer aims …

The Effectiveness Of Teaching Life Skills Through Sport-Based Interventions For At-Risk Youth, Melinda Katheran Scott

Electronic Theses and Dissertations

At-risk youth are children and adolescents who live in a negative environment and/or do not possess the skills they need in becoming responsible members of society (Collingwood, 1997). Many of these youth experience adjustment difficulties, behavioral problems, academic failure and dropout, or mental health difficulties (Moreau et al., 2012). One of the current resources for these youth has been sport-based interventions or physical activity to measure the benefits of psychosocial wellbeing among the adolescents. However, these have typically been outreach projects rather than research based. The current study analyzed the effectiveness of a life skills program called SUPER that used …

Improving The Inference Of Some Experiemtal Studies By Using Ranked Auxiliary Covariates, Rajai Jabrah

Electronic Theses and Dissertations

In many studies, the measurement of sampling units according to the response variable is costly or time consuming, however, it is possible to rank sampling units according to baseline auxiliary covariates, which are available, easily obtainable, and cost efficient. In these cases, when estimating the population mean, Ranked Set Sampling (RSS) can be a more efficient sampling method than the Simple Random Sampling (SRS) method. In this dissertation, we propose a modified approach of the RSS method to allocate units into an experimental study, aimed to compare two or more groups.

Ranked auxiliary covariates, which are typically correlated with the …

Experimental And Numerical Investigation Of Aerodynamic Performance For Vertical-Axis Wind Turbine Models With Various Blade Designs, Travis E. Salyers

Electronic Theses and Dissertations

The demand for wind energy as a renewable source is rising substantially. A growing interest exists in utilizing potential energy conversion applications in areas with less powerful and less consistent wind conditions. In these areas, vertical-axis wind turbines (VAWTs) possess several advantages over the conventional horizontal-axis type. Savonius turbines are drag-based rotors which operate due to a pressure difference between the advancing and retreating blades. These turbines are simpler in design, less expensive to install, non-dependent of wind direction, and more efficient in lower wind speeds. In the present study, six different rotor designs with equal swept areas are analyzed …

Type 2 diabetes has become a serious issue affecting millions of Americans, especially in the southern United States. Georgia is one southern state where diabetes rates are high. Diabetes is exacerbated in rural areas where many communities are medically underserved. Therefore, diabetes prevention interventions that target rural communities in the South are needed to address this issue. Traditional methods of addressing diabetes in the South have not been effective. Innovative methods, such as worksite prevention programs, must be developed to combat the problem. The purpose of this study was to assess the feasibility of the employer as a health advisor …

The Moderating Effects Of Positive And Negative Automatic Thoughts On The Relationship Between Positive Emotions And Resilience, Michael W. Judd

Electronic Theses and Dissertations

Resilience is generally characterized as the ability to recover and grow following adversity (Connor & Davidson, 2003) and is considered an integral factor in the promotion of overall physical and psychological health (Masten & Reed, 2002). One factor thought to be associated with resilience is more frequent positive emotions, but the relationship between positive emotions and resilience varies (Tugade, Fredrickson, & Feldman-Barrett, 2004), suggesting moderating factors may be involved. Cognitive factors may be involved in determining the parameters that define when and to what degree this relationship occurs (Troy & Mauss, 2011). The current study was designed to further elucidate …

Biogeographical Patterns In The Hard-Tick Genus Amblyomma Koch 1844 (Acari: Ixodidae), Matthew H. Seabolt

Electronic Theses and Dissertations

Amblyomma Koch is a genus of hard-ticks with approximately 130 species. Its geographical range is typical for organisms with a Gondwanan origin. A majority of these species are endemic to the Neo- and Afrotropical regions, with the remaining taxa dispersed throughout Southeast Asia, Australia and the Pacific islands. Based on this distribution, we hypothesize that the genus dispersal patterns will mirror the fragmentation and continental drift of the Gondwanan supercontinent. Maximum parsimony, maximum likelihood, Bayesian inference and node-dating analyses of nuclear 18S rDNA gene sequences reveal a more recent origin and radiation patterns within the genus and suggest that Amblyomma …

The German Hun In The Georgia Sun: German Prisoners Of War In Georgia, Leisa N. Vaughn

Electronic Theses and Dissertations

Studies of prisoners of war in America have received renewed attention since the opening of the prisoner facility at Guantanamo Bay, Cuba. However, this is not a new field of scholarship. Since the 1970s, with Arnold Krammer’s Nazi Prisoners of War in America, American treatment of prisoners, especially during WWII,has flourished as a field. Increasingly popular in the 1980s were statewide studies of prisoner of war camps and the captive experience. Despite this focus, Georgia’s role in prisoner of war administration and the captive’s experiences have been overlooked. This thesis seeks to remedy this gap.

Georgia housed prisoners of …

All The News That’S Fit To Sing: Phil Ochs, Vietnam, And The National Press, Thomas C. Waters

Electronic Theses and Dissertations

ABSTRACT

Though a prolific topical musician and a prominent figure of the antiwar movement during the 1960s, Phil Ochs remains relatively understudied by scholars due to the lure of more commercially successful folk artists like Bob Dylan and Joan Baez. His music facilitated awareness of pressing, and sometimes controversial, issues that would otherwise have not been discussed. Focusing on Ochs’ most musically productive years from 1964 until 1968, which coincide with the years of increased American involvement in Southeast Asia, this thesis analyzes Ochs in a way that has not been attempted before. It places his anti-Vietnam War songs in …

Understanding Workday Ego Depletion And The Role Of Gratitude Recovery Techniques, Alexandria Steele

Electronic Theses and Dissertations

Everyday activities require the use of self-control resources to regulate behaviors. Ego depletion is the idea that the use of self-control resources on one task results in reduced self-control resources for subsequent tasks. The current study aims to examine ego depletion as a result of a simulated workplace task, design a gratitude recovery technique for workplace ego depletion, and observe child punishment as a potential outcome of workplace ego depletion. A dual-task procedure in which participants completed a complex logic assessment while also listening to a background narrative mimicked workplace environments. Gratitude recovery consisted of recalling people, items, or events, …

Throughout recorded history, children have been subjected to sexual exploitation. Child predators and pedophiles often take great risk and go to extreme lengths to sexually exploit a child. With technological advancements many individuals became globalized and connected with the invention of the computer, the internet and its attributes. However, child predators quickly took note of the vulnerability of children as they begin to groom them online. The problem quickly evolved as the Deep (Dark) Web and encryption were created. This put great stress upon law enforcement entities as locating and combating these predators became exhausting tasks. It’s most often that …

The Influence Of Emotion On Memory For A Crime, Taylor Langley

Electronic Theses and Dissertations

Researchers have reported errors in recall or recognition of witnessed events, accounting for the most common cause of false convictions of innocent people. Tiwari (2010) indicated that 25% of suspects who were identified in a line-up were actually innocent. Jurors are strongly influenced by eyewitness testimony and this can lead to false convictions. The validity of eyewitness identification is critical in cases in which it is used as evidence. In the current study we examined specific emotion states by inducing fear, surprise, and neutral moods. We hypothesized that participants in the Fear group would be least susceptible to the effects …
