The Impact Of A Modified Cooperative Learning Technique On The Grade Frequencies Observed In A Preparatory Chemistry Course, Bridget J. Hayes Russell

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation explored the impact of a modified cooperative learning technique on the final grade frequencies observed in a large preparatory chemistry course designed for pre-science majors. Although the use of cooperative learning at all educational levels is well researched and validated in the literature, traditional lectures still dominate as the primary methodology of teaching. This study modified cooperative learning techniques by addressing commonly cited reasons for not using the methodology. Preparatory chemistry students were asked to meet in cooperative groups outside of class time to complete homework assignments. A chi-square goodness-of-fit revealed that the final grade frequency distributions observed …

Survey Of Response-To-Intervention's Challenges For School-Based Speech-Language Pathologists, Jane D. Simmerman

Graduate Theses, Dissertations, and Problem Reports (ETD)

With the introduction of the No Child Left Behind Act (NCLB), speech-language pathologists (SLPs) have experienced a new focus on language and literacy within their roles and responsibilities to provide services to students. The American Speech and Hearing Association (ASHA) support the role of SLPs in literacy efforts through their policies regarding expanded roles and responsibilities for school-based SLPs. ASHA notes that school-based SLPs have a clearly defined role in Response to Intervention (RTI) based on their expertise, knowledge and training to provide services as a resource and an interventionist when appropriate. The effect of the redefined roles and responsibilities …

Parental Support And Pressure In Sports And Children's Anger, Sadness, And Worry Regulation, Cara A. Palmer

Graduate Theses, Dissertations, and Problem Reports (ETD)

Despite large amounts of child sport participation, research suggests that this activity is not always associated with positive outcomes for youth. This study examined factors that might contribute to discrepant findings associated with youth sports participation. Specifically, parental pressure and support in competitive soccer families and its relation to their children's general emotion regulation were examined. Participants were 91 parent-child dyads (49 males, 42 female, 67 moms, 23 dads) with children between the ages of 8-12 years (M = 10.24, SD = 1.19). Children completed several self-report measures on their parent's pressure and support behaviors in general and in soccer, …

Hyperreal Battlefields: Individual Action And The Composition Of Enemy In Call Of Duty: Modern Warfare 1 & 2, Jeffrey Allen Yeager

Graduate Theses, Dissertations, and Problem Reports (ETD)

Speculative fictions present us with stories that ask the question "what if?" In the past decades there has been a noticeable increase in the amount of speculative fiction in Western popular media. War-themed video games represent one of the most popular interactive texts that have embraced the speculative fiction genre. There is a multitude of research that examines non-fiction war games and those based loosely on some actual or historical conflict. This research diverges from that path by analyzing the narrative and structure of a series of fictional war games set in the modern era. The game presents a narrative …

Behavior That Hurts: Theoretical Orientation, Terminology, And Diagnosis Of Self-Injury, Susannah C. Rowan Flamm

Graduate Theses, Dissertations, and Problem Reports (ETD)

Self-injurious behavior prevalence continues to rise in both adolescent and adult non-clinical populations and within adolescent and adult clinical populations. Despite a large volume of literature regarding the antecedents and functions of self-injury, exploration of clinician factors in regard to these clients is sparse. This study examined the associations among 346 doctoral level clinicians' theoretical orientations, preferred terminology to describe self-injurious behaviors, and preferred diagnoses for clients who engage in self-injury. Therapist variables such as age, years in practice, and gender were examined for their association with terminology and diagnostic preferences. Chi-square analyses were conducted for the two-way interactions and …

Report On Advances In The Field Of Artificial Intelligence Attributed To Captcha, Craig M. Schow

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

A CAPTCHA is a specialized human interaction proof that exploits gaps between human and computer recognition abilities. By design, the hardness of a CAPTCHA is based on the difficulty of advancing the underlying artificial intelligence [AI] technology to a level that eliminates any exploitable gap. Due to this fact computer scientists have concluded that the widespread use of CAPTCHA would accelerate research in the underlying fields of AI eventually leading to near-­‐human capabilities in certain AI systems. Despite these predictions no attempt has been made to identify advances in AI which can be attributed to the use of CAPTCHA.

Closed-Loop Attitude Control Using Fluid Dynamic Vectoring On An Aerospike Nozzle, Nathan Erni

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Attitude control of a prototype satellite bus using fluid mechanical vectoring on an aerospike nozzle is demonstrated. The design achieves thrust vectoring by injecting propellant asymmetrically into the unconstrained aerospike exhaust plume near the nozzle base. The prototype system uses cold-gas thrusters to both spin-up and de-tumble the test article. The system is configured with axially directed annular flows that produce large longitudinal thrusts and smaller secondary lateral-injection flows for side thrusts. Both open and closed-loop attitude control, with and without main aerospike annular flow active, are demonstrated. Proportional, integral, derivative (PID) regulation is used for closed-loop attitude control. When …

A Model For Rapid Charging Events On International Space Station, Debrup Hui

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Surface charging by plasma can be a serious issue for any spacecraft. Though significant charging is not observed in all spacecrafts at all times, it only requires a single episode of extreme charging to result in serious damage. The International Space Station (ISS) is an interesting platform to study these charging effects because of its size and relatively high voltage systems. Of the many kinds of charging observed on ISS, the rapid charging events during solar eclipse exit in a low-density ionosphere is not yet understood. This report is an investigation to understand this phenomenon. This report proposes a simple …

Critical Review Of Inundation Mapping Procedures For Floodplain Management, Richard M. Wise

Graduate Theses, Dissertations, and Problem Reports (ETD)

Inundation mapping is a major component of floodplain management, providing critical information as to the consequences of potential failures of flood control structures, such as dams. To develop inundation maps, a dam and river system are modeled with engineering computer programs, and a simulation of the dam failure is performed to generate data for the flood. This output data is input into other programs to develop inundation maps. Inundation maps have traditionally been produced in a paper format, but recent advances in computer modeling have provided the capability for virtual inundation maps. Thus, these mapping methods need to be investigated …

The Nature Of Context-Sensitive Solutions, Stakeholder Involvement And Critical Issues In The Urban Context, Marta Panero, Jan Botha

Mineta Transportation Institute

Over the last several decades many transportation and planning agencies have experienced conflicting demands emerging from the need to develop projects in an expeditious manner while at the same time involving stakeholders in the decision-making process, which sometimes is perceived as slowing project delivery and/or increasing costs. Given this tension between apparently conflicting demands, it is important to understand how the stakeholder involvement is being carried out and what best practices may be recommended. This study examines the issue in the context of a relatively new policy framework – Context Sensitive Solutions (CSS) – which supports the early integration of …

The Social Transformation Of Coffee Houses: The Emergence Of Chain Establishments And The Private Nature Of Usage, Dawn Marie Lozzi

Graduate Theses, Dissertations, and Problem Reports (ETD)

Much attention is given to Ray Oldenburg's (1989) concept of third places as environments that offer visitors friendship and a sense of community. However, given that coffee houses have moved from small-scale businesses to chain-owned and many people now use them to work on laptops, this idealized image of the coffee house also may be changing. Few empirical studies have addressed such possibilities. Using unobtrusive observation data on three independently-owned coffee houses and three chain-based coffee houses, this research examines the concept of third places to better understand the ways in which modern coffee houses live up to Oldenburg's social …

Then in Chapter III, a single FET device mixer is studied and its conversion loss is found from its small-signal model. The chapter will then include a two FET device mixer and a four device FET mixer. Finally a new type of mixer will be discussed in Chapter IV. The new type of mixer is a 3 phase mixer with the phase angles being 0°, 120°, and 240°. The …

Sexuality Education, Eva Goldfarb, Norman A. Constantine

Department of Public Health Scholarship and Creative Works

Sexuality education comprises the lifelong intentional processes by which people learn about themselves and others as sexual, gendered beings from biological, psychological, and sociocultural perspectives. It takes place through a potentially wide range of programs and activities in schools, community settings, religious centers, as well as informally within families, among peers, and through electronic and other media. Sexuality education for adolescents occurs in the context of the biological, cognitive, and social-emotional developmental progressions and issues of adolescence. Formal sexuality education falls into two main categories: behavior change approaches, which are represented by abstinence-only and abstinence-plus models, and healthy sexual development …

Peddlers Of Hate: The Existence Of Norm Entrepreneurs As A Necessary Precursor To Genocide, Lauren Elise Fairbanks

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Over the course of the 20th century genocide has been responsible for the murder of more than 170 million people; it is has proven to be four times deadlier than war (Voth, 2007). Although it often appears spontaneous, Genocide is instead a result of certain preconditions. Studies into the causes of genocide ought to aid in the formation of methods intended to keep violence from occurring. Unfortunately, seemingly different factors such as economic crisis, resource scarcity, institutional weakness, and ethnic resentment prove difficult to classify as the ultimate cause. Instead these conditions work collectively to create an atmosphere that is …

Development, Implementation, And Evaluation Of A Social Skills Training Intervention In A Rural Special-School Setting For Students With Mild/Moderate Disabilities, Sheree Duncan

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Given the critical degree to which a person’s level of social competence influences one’s academic, mental, social, and interpersonal success, it is imperative that schools facilitate the learning of social skills. The purpose of this study was to design, implement and evaluate a social skills training intervention for students with mild disabilities (and behaviors that adversely affect their participation in a general curriculum or resource settings) in a rural special school setting. A review of literature guided the design and evaluation of the intervention. According to analysis of data on student behavior, the social skills training intervention did not consistently …

Low Power Wake-Up Signaling For Dense Sensor Networks, Ahmed M. Abuseta Ammar

Graduate Theses, Dissertations, and Problem Reports (ETD)

In wireless sensor networks, nodes are required to reduce their idle listening time in order to minimize energy consumption and increase their lifetime. The idle listening time is decreased by making the nodes remain in sleep mode and wake up only when they are required to sense or transmit information about an event. This strategy requires the source node to send a wake-up signal before it transmits data to the network. This wake-up signal requires energy and the objective of this work is to lower this signal's energy consumption.;In order to achieve this, this work uses Near Field Magnetic Induction …

Religious Affiliation And Attendance As Predictors Of Immigration Attitudes In Nebraska, Courtney Lyons Breitkreutz

Department of Sociology: Dissertations, Theses, and Student Research

This study examines the relationship between religious affiliation, church attendance, and attitudes towards immigration. Following the ethnoreligious perspective, I predict that those who identify as Mainline Protestant, Evangelical Protestant, or Catholic will hold more positive attitudes than those who do not affiliate, which would reflect the teachings of their churches. I also predict that Catholics may have particularly positive attitudes because of social identity theory. Attending church services should be associated with more positive attitudes, according to religious restructuralism. Using 2006 telephone survey data of 1,135 Nebraskans from the Nebraska Annual Social Indicators Survey (NASIS), I use binary logistic regression …

Impact Of Computerized “Sounding Out” On Spelling Performance Of A Child Who Uses Aac: A Preliminary Report, Jillian H Mccarthy, David R. Beukelman, Tiffany Hogan

Department of Special Education and Communication Disorders: Faculty Publications

Spelling is a vital skill for people who rely on augmentative and alternative communication (AAC). The ability to spell words provides an opportunity to create novel and spontaneous communication and increases educational, social, and employment opportunities for children and adults. However, many children and youth who rely on AAC struggle to gain functional spelling skills and written language. The purpose of this preliminary investigation was to develop a strategy to provide auditory letter-sounds using commercially available computer equipment and to evaluate how such a computerized “sounding out” strategy influences spelling accuracy for one child who required AAC support. The spelling …

Content-Based Social Network Analysis Of Mailing Lists, Angela Bohn, Ingo Feinerer, Kurt Hornik, Patrick Mair

The R Journal

Social Network Analysis (SNA) provides tools to examine relationships between people. Text Mining (TM) allows capturing the text they produce in Web 2.0 applications, for example, however it neglects their social structure. This paper applies an approach to combine the two methods named “content-based SNA”. Using the R mailing lists, R-help and R-devel, we show how this combination can be used to describe people’s interests and to find out if authors who have similar interests actually communicate. We find that the expected positive relationship between sharing interests and communicating gets stronger as the centrality scores of authors in the communication …

The Economics And Logistics Of The Dual Harvest Of Grain And Biomass In A Single-Pass, Matthew T. Wold

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Significant interest has developed in using cellulosic resources, especially crop residues, to create biofuels. Collecting these residues in a single-pass of the harvester across the field has the potential to be a low cost option. Two models have been developed; the first characterizes the in-field logistics of single-pass crop residue collection, the second the economics. These models allow the user to easily examine a wide variety of both grain-only and single-pass residue collection harvest cases. A variety of possible residue collection cases have been examined, and their effects both on harvester field capacity and harvest cost compared to grain-only harvest …

Analysis Of Turnip Crinkle Virus Effects On The Innate And Adaptive Immunity In Arabidopsis Thaliana, Teresa J. Donze

School of Biological Sciences: Dissertations, Theses, and Student Research

The ability to understand the interactions between plants and the variety of pathogens they encounter on a daily basis is an important area of research. In the following work presented in this dissertation, I sought to better understand the mechanisms that Turnip crinkle virus (TCV) employs to elude the defense responses of the host plant Arabidopsis thaliana. It was previously determined that TCV coat protein (CP) interacts with a transcription factor, TIP, within the about 10 amino acid region near the N-terminus of the CP called the R-domain. When this interaction was disrupted by making single amino acid substitutions …
