Multi-Scale Analysis Of Regional Inequality Based On Spatial Field Model: A Case Study Of China From 2000 To 2012, Shasha Lu, Xingliang Guan, Danlin Yu, Yu Deng, Linjie Zhou

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

A large body of recent studies-from both inside and outside of China-are devoted to the understanding of China's regional inequality. The current study introduces "the spatial field model" to achieve comprehensive evaluation and multi-scale analysis of regional inequality. The model is based on the growth pole theory, regional interaction theory, and energy space theory. The spatial field is an abstract concept that defines the potential energy difference that is formed in the process of a regional growth pole driving the economic development of peripheral areas through transportation and communication corridors. The model is able to provide potentially more precise regional …

Attitudes And Perceptions Of Suicide And Suicide Prevention Messages For Asian Americans, Priyata Thapa, Yoonhee Sung, David A. Klingbeil, Chih-Yuan Lee, Bonnie Klimes-Dougan

Department of Family Science and Human Development Scholarship and Creative Works

Understanding the context of suicidal behaviors is critical for effective suicide prevention strategies. Although suicide is an important topic for Asian Americans, there is limited information about what Asian Americans' attitudes are towards suicide and their perceptions about the effectiveness of prevention efforts. These questions are critical to examine to provide foundational knowledge for determining how best to intervene. In this study, Asian American (n = 87) and White (n = 87) participants completed self-report indexes on their knowledge of depression and suicide (e.g., estimates of suicide rates), coping attitudes (e.g., help-seeking) and suicide prevention attitudes (e.g., usefulness of PSAs). …

Animal Cities: Post-Human Urban Wildness, Jing Huang Dec 2015

Animal Cities: Post-Human Urban Wildness, Jing Huang

Architecture Thesis Prep

This thesis contends that architecture should be designed in a way to foster closer human-animal relationships. Cities are typically designed solely with the human in mind, and over time, animals have been pushed out of the city, decreasing biodiversity. Peoples’ tendency is to separate themselves and domesticate animals, resulting in sterile and tame urban centers. This is a result of the different attitudes humans have cultivated towards animals; dirty/clean, pleasant/annoying, useful/useless, harmless/dangerous, awe/disgust, etc., and utilizing architecture as means of filtering the presence of those that are beneficial to us, rendering animals as an afterthought. In a way, humans have …

Changing Behavior, Brain Differences, Or Both? A Review Of Effective Adhd Treatment, Devin Hilla Dec 2015

Changing Behavior, Brain Differences, Or Both? A Review Of Effective Adhd Treatment, Devin Hilla

Honors Projects

Much debate exists over the proper course of treatment for individuals with attention-deficit/hyperactivity disorder (ADHD). Stimulant medications, such as methylphenidate (e.g., Ritalin) and amphetamine (e.g., Adderall), have been shown to be effective in managing ADHD symptoms. More recently, non-stimulant medications, such as atomoxetine (e.g., Strattera), clonidine (e.g., Kapvay), and guanfacine (e.g., Intuniv), have provided a pharmacological alternative with potentially lesser side effects than stimulants. Behavioral therapies, like behavioral parent training, behavioral classroom management, and behavioral peer interventions, have shown long-term benefits for children with ADHD; however, the success of the short-term management of ADHD symptoms is not as substantial when …

Development And Implementation Of Hay Yield Monitoring Technology, Henry Ramsey Dec 2015

Development And Implementation Of Hay Yield Monitoring Technology, Henry Ramsey

All Theses

Three independent technologies related to hay yield monitoring were developed and studied. One technology involved comparison of infrared and ultrasonic sensors on a self-propelled forage harvester. Sensor response related to grass height and was used to estimate yield. Plots that were harvested ranged from 20-40 ft. in length while a bin mounted on the back of the mower collected the crop for weighing and sampling. The infrared sensors data demonstrated accuracies across plots between 5.9% and 9.5% error. The infrared sensors quickly deteriorated and eventually proved to be useless for data acquisition. As for the ultrasonic sensors, they demonstrated similar …

Co-Design Of Dynamic Real-Time Scheduling And Cooperative Control For Human-Agent Collaboration Systems Based On Mutual Trust, Xiaotian Wang Dec 2015

Co-Design Of Dynamic Real-Time Scheduling And Cooperative Control For Human-Agent Collaboration Systems Based On Mutual Trust, Xiaotian Wang

All Theses

Mutual trust is a key factor in human-human collaboration. Inspired by this social interaction, we analyze human-agent mutual trust in the collaboration of one human and (semi)autonomous multi-agent systems. In the thesis, we derive time-series human-agent mutual trust models based on results from human factors engineering. To avoid both over- trust and under-trust, we set up dynamic timing models for the multi-agent scheduling problem and develop necessary and sufficient conditions to test the schedulability of the human multi-agent collaborative task. Furthermore, we extend the collaboration between one human and multiple agents into the collaboration between multi-human network and swarm-based agents …

The Performance Of Quaternary Amplitude Modulation With Quaternary Spreading In The Presence Of Interfering Signals, Allison Manhard Dec 2015

The Performance Of Quaternary Amplitude Modulation With Quaternary Spreading In The Presence Of Interfering Signals, Allison Manhard

All Theses

Multiple-access digital communications is considered with direct-sequence spread-spectrum (DS-SS) quadrature amplitude modulation and quaternary spreading in each transmission. Each transmitted signal undergoes attenuation and a delay at a receiver in the additive white Gaussian noise channel. The receiver uses coherent demodulation with a correlation detector synchronized to the one of the K received signals so that the K - 1 other transmissions act as interference. The average probability of error at the output of the detector is determined using Monte Carlo simulation and compared with an approximation in which the interference component in each detection statistic is approximated by a …

Eye Tracking Recycle Labels On Packaging: Are Attitudes And Behaviors A Predictor Of Viewing Them?, Valerie Smith Dec 2015

Eye Tracking Recycle Labels On Packaging: Are Attitudes And Behaviors A Predictor Of Viewing Them?, Valerie Smith

All Theses

In the United States, the use of the chasing arrows is the most recognizable label for consumers to interpret the recyclability of packaging and other materials. Yet, the use of the label can be used interchangeably for different purposes, which may lead to misinterpretation of the label. Recently, the Sustainable Packaging Coalition (SPC) revamped the recycle label to provide more information, avoid confusion, and misinterpretation. Recycle rates have only increased seven percent in the past decade. Furthermore, there is a lack of research about the utility of recycle labels in efforts to increase recycling rates. The over-arching goals of this …

The Mediating Effects Of Positive Psychological States On The Relationships Between Hindrance Stressors And Organizational Citizenship Behaviors: A Multi-Level Approach, Kandice Goguen

All Theses

Organizational citizenship behaviors (OCBs) are informal and voluntary behaviors that positively contribute to organizational functioning (Organ 1997; Katz & Kahn, 1978). To better understand and encourage such behaviors, the present study investigated the influence of hindrance stressors and positive psychological states in the workplace. Responses from a sample of university employees were analyzed to examine the individual and unit-level effects of role ambiguity, organizational constraints, and lack of job control on individual-level supervisor-rated OCBs through individual and unit-level positive psychological states. Results showed that each hindrance stressor negatively influenced OCB participation directly and through decreased positive psychological states at the …

Electrical Characterization Of Gold And Platinum Thin Film Electrodes With Polyaniline Modified Surfaces, John Aggas Dec 2015

Electrical Characterization Of Gold And Platinum Thin Film Electrodes With Polyaniline Modified Surfaces, John Aggas

All Theses

Recent studies into soft organic electronics have burgeoned as a result of discoveries of conducting polymers such as polyaniline, polythiophene, and polypyrrole. However, in order to make these conducting polymers suitable for in vivo soft organic electronics, they must be developed so that they can be biocompatible and provide accurate sensing. Chitosan, a naturally occurring polymer structure found in exoskeletons of crustaceans, has been studied for its biocompatible properties. Composites of polyaniline (PAn), an intrinsically conductive polymer (ICP) and chitosan (Chi), a biopolymer, were developed and applied to gold and platinum Thin Film Electrode (TFE) devices.
