Changing Transitions To Adulthood In Vietnam's Remote Northern Uplands: A Focus On Ethnic Minority Youth And Their Families, Bussarawan Teerawichitchainan, Hac Van Vinh, Nguyen Thi Phuong Lan Jan 2007

Changing Transitions To Adulthood In Vietnam's Remote Northern Uplands: A Focus On Ethnic Minority Youth And Their Families, Bussarawan Teerawichitchainan, Hac Van Vinh, Nguyen Thi Phuong Lan

Poverty, Gender, and Youth

Ethnic minorities, who tend to live in remote mountainous areas, account for 15 percent of Vietnam’s 84 million total population and, according to a recent estimate, 61 percent of them are poor. Evidence suggests that despite recent efforts by the Government of Vietnam to promote poverty reduction in remote areas, a majority of ethnic minorities have not yet experienced positive change, contrary to their Kinh (ethnic Vietnamese) neighbors who have enjoyed substantial improvement in living standards. To identify program interventions that promote healthy human development and, in turn, positively affect Vietnam’s economic growth, it is crucial to have a comprehensive …

Estimation And The Stress-Strength Model, Naomi Brownstein Jan 2007

Estimation And The Stress-Strength Model, Naomi Brownstein

HIM 1990-2015

The paper considers statistical inference for R = P(X < Y) in the case when both X and Y have generalized gamma distributions. The maximum likelihood estimators for R are developed in the case when either all three parameters of the generalized gamma distributions are unknown or when the shape parameters are known. In addition, objective Bayes estimators based on non informative priors are constructed when the shape parameters are known. Finally, the uniform minimum variance unbiased estimators (UMVUE) are derived in the case when only the scale parameters are unknown.

The Effects Of Blocked And Random Word Lists On The Production Of False Memories, Melonie Williams Jan 2007

The Effects Of Blocked And Random Word Lists On The Production Of False Memories, Melonie Williams

HIM 1990-2015

This study separated participants into four different conditions based on a 2 (blocked or random study trials) x 2 (blocked or random test trials) between-subjects design. Using the Deese-Roediger-McDermott (DRM) paradigm the researcher investigated whether or not false memories were produced at the time of study or the time of test. According to the paradigm, participants who view a series of categorical words (mad, fear, hate, rage, temper) are thought to semantically associate critical lures (anger), as a part of the list presented, more frequently than participants who see a string of unrelated terms. The production of false memory is …

The Development Of Intergroup Bias In Children To Ambivalent Sexism In Adults: A Study Of The Role Of Self-Esteem, Noel E. Thomas Wrend

HIM 1990-2015

Gender differences play an important role in the diversity that exists in our world today. Evan as infants, our young minds are able to grasp that there are large differences in the roles and expectations for males and females and that these differences contribute to the variety of experiences that we encounter in our interactions with the two genders. As we grown from children into adults, it is clear that the biased opinions we form regarding the opposite sex in childhood are too simplistic in their ideologies, and during the time that we mature into young adults, our opinions mature …

A Comparison Of Attentional Reserve Capacity Across Three Sensory Modalities, John Brill Jan 2007

A Comparison Of Attentional Reserve Capacity Across Three Sensory Modalities, John Brill

Electronic Theses and Dissertations

There are two theoretical approaches to the nature of attentional resources. One proposes a single, flexible pool of cognitive resources; the other poses there are multiple resources. This study was designed to systematically examine whether there is evidence for multiple resource theory using a counting task consisting of visual, auditory, and tactile signals using two experiments. The goal of the first experiment was the validation of a multi-modal secondary loading task. Thirty-two participants performed nine variations of a multi-modal counting task incorporating three modalities and three demand levels. Performance and subjective ratings of workload were measured for each of the …

Friend/Foe Identification Accuracy And Shooting Performance: Effects Of Prior Task Loading And Time Pressure, Kelly Ann Burke Jan 2007

Friend/Foe Identification Accuracy And Shooting Performance: Effects Of Prior Task Loading And Time Pressure, Kelly Ann Burke

Electronic Theses and Dissertations

The current dismounted soldier and the soldier of the future will be "loaded" with more information processing tasks while they perform shooting tasks. It is conceivable that some increased level of cognitive tasking may be performed simultaneously with required shooting tasks. The effect of cognitive load on shooting performance has been previously examined (Scribner and Harper, 2001). This study concentrated on the effect of various cognitive workload demands on a friend-foe discrimination shooting task in a single- and dual-task scenario. In light of this, it is imperative that the soldier not be overburdened mentally, which may result in decreased survivability …

The Effects Of Eicu Technology On Clinical Outcomes Of Icu Patients: Analysis Of The Relationship Of Patient, Hospital, And Unit Characteristics To Proximal And Distal Outcomes, Michelle G. Chandler

Electronic Theses and Dissertations

Each year approximately five million people are treated in the nation's intensive care units making intensive care one of the most expensive components of the U.S. healthcare system. Of these patients, 400,000-500,000 will die annually giving the ICU the distinction of having the highest rate of mortality and complications in the hospital setting. Studies have demonstrated that one in ten patients who die each day in ICUs might survive if intensivists were present to manage clinical care and direct treatment plans (Randolph & Pronovost, 2002; Dimick, Pronovost, Heitmiller & Lipsett, 2001; Pronovost et al., 2002). The utilization of supplemental remote …

Scalable Volumetric Three-Dimensional Up-Conversion Display Medium, Jung-Hyun Cho Jan 2007

Scalable Volumetric Three-Dimensional Up-Conversion Display Medium, Jung-Hyun Cho

Electronic Theses and Dissertations

There are many different techniques to display 3D information. However, not many of them are able to provide sufficient depth cues to the observers to sense or feel the images as real three-dimensional objects. Volumetric three-dimensional displays generate images within a real 3D space, so they provide most of the depth cues automatically. This thesis discusses the basic notions required to understand three-dimensional displays. Also discussed are different techniques used to display 3D information and their advantages and disadvantages as well as their current limitations. Several rare-earth doped fluoride crystals that are excited to emit visible light by sequential two …

Far-Infrared/Millimeter Wave Source And Component Development For Imaging And Spectroscopy, Todd Du Bosq Jan 2007

Far-Infrared/Millimeter Wave Source And Component Development For Imaging And Spectroscopy, Todd Du Bosq

Electronic Theses and Dissertations

The far-infrared and millimeter wave (FIR/mmW) (wavelength 75 micrometer to 10 mm) portion of the electromagnetic spectrum is fairly underdeveloped technologically, owing to the large amount of atmospheric attenuation in that range. At present, the FIR/mmW region is lacking in compact, high-brightness radiation sources and practical imaging systems. This dissertation focuses on development of two complementary technologies in this area - an active mmW imaging system and high-reflectivity Bragg mirrors for the FIR p-Ge laser. The imaging system uses a vector network analyzer in the frequency range of 90-140 GHz as the radiation source and receiver. Raster scanning is used …

Representations Of The Catholic Inquisition In Two Eighteenth-Century Gothic Novels: Punishment And Rehabilitation In Matthew Lewis' The Monk And Ann Radcliffe's The Italian, Jarad Fennell Jan 2007

Representations Of The Catholic Inquisition In Two Eighteenth-Century Gothic Novels: Punishment And Rehabilitation In Matthew Lewis' The Monk And Ann Radcliffe's The Italian, Jarad Fennell

Electronic Theses and Dissertations

The purpose of this thesis is to determine how guilt and shame act as engines of social control in two Gothic narratives of the 1790s, how they tie into the terror and horror modes of the genre, and how they give rise to two distinct narrative models, one centered on punishment and the other on rehabilitation. The premise of the paper is that both Matthew G. Lewis's The Monk and Ann Radcliffe's The Italian harness radically different emotional responses, one that demands the punishment of the aberrant individual and the other that reveres the reformative power of domestic felicity. The …

Categorical Properties Of Lattice-Valued Convergence Spaces, Paul Flores Jan 2007

Categorical Properties Of Lattice-Valued Convergence Spaces, Paul Flores

Electronic Theses and Dissertations

This work can be roughly divided into two parts. Initially, it may be considered a continuation of the very interesting research on the topic of Lattice-Valued Convergence Spaces given by Jager [2001, 2005]. The alternate axioms presented here seem to lead to theorems having proofs more closely related to standard arguments used in Convergence Space theory when the Lattice is L = f0; 1g:Various Subcategories are investigated. One such subconstruct is shown to be isomorphic to the category of Lattice Valued Fuzzy Convergence Spaces defined and studied by Jager [2001]. Our principal category is shown to be a topological universe …

Parameter Estimation Using Sensor Fusion And Model Updating, Kevin Francoforte Jan 2007

Parameter Estimation Using Sensor Fusion And Model Updating, Kevin Francoforte

Electronic Theses and Dissertations

Engineers and infrastructure owners have to manage an aging civil infrastructure in the US. Engineers have the opportunity to analyze structures using finite element models (FEM), and often base their engineering decisions on the outcome of the results. Ultimately, the success of these decisions is directly related to the accuracy of the finite element model in representing the real-life structure. Improper assumptions in the model such as member properties or connections, can lead to inaccurate results. A major source of modeling error in many finite element models of existing structures is due to improper representation of the boundary conditions. In …
