Elucidation Of Pharmacologically Manipulated Responding In The Delay Discounting Task In High Alcohol Preferring Mice, Meredith Halcomb

Open Access Dissertations

Impulsive behavior is the hallmark of many psychopathologies. Uncovering the neurobiological mechanisms driving impulsivity is paramount in the development of through the delay discounting (DD) task in both human and animal models. The present study is an examination of the predictive validity of the two primary types of DD procedures in animals, the Adjusting Amounts (AA) and within session Increasing Delays (ID) tasks. Methods:Subjects were administered either1.25 mg/kg d-amphetamine (AMP), 1.5 g/kg ethanol (EtOH) or saline and tested in either the AA or ID method for 15 days to evaluate drug effects on impulsive behavior. Results: Stimulant administration resulted …

Public Understanding Of Chemistry Research In Print News, Michael D. Hands

Open Access Dissertations

Despite numerous calls for improving scientific literacy, many American adults show a lack of understanding of experiments, scientific study, and scientific inquiry. News media is one important avenue for science learning, but previous research investigating health and/or environmental science news has shown that it is inconsistent in the presentation of scientific research limitations, potentially impacting reader understanding. In the first phase of this dissertation, seventeen news articles reporting on a single chemistry research article, along with associated press releases and research articles, were analyzed using move analysis to determine the structure of each type of text. It was found that …

Food Security In The Free State Province: Meaning Making As Democratic Agency, Jacqueline Del Valle Hanoman Ambrosio

Open Access Dissertations

People's stories are powerful means of explaining their realities, for their narratives reveal what meanings they make of the situations they are living, how they face these situations and what strategies they formulate to overcome them. Their meaning making is one of the most powerful tools of their agency, and this is what this study reveals. In it, I tell the stories of people in the Free State Province, South Africa, who face food insecurity within abundance, and their critical consciousness and agency as they struggle to survive in their democracy. Poverty is a rawness...Poverty is struggle... Poverty is shame...these …

Cerebrovascular Reactivity Alterations Due To Subconcussive Repetitive Head Trauma In Asymptomatic High School Football Players, Chetas Joshi

Open Access Theses

Chronic neurological damage as a result of chronic repetitive head trauma is a major concern for football athletes today. Repetitive concussions have been linked to many neurological disorders. Recently, it has been reported that repetitive subconcussive events can contribute to long-term neurodegeneration. For these reasons, it is important to understand the effect repetitive subconcussive head trauma has on brain health in young athletes. Past research has demonstrated that cerebrovascular reactivity (CVR), an important mediator of cerebrovascular regulation, is impaired following mild traumatic brain injury (mTBI). This impairment increases susceptibility to secondary injury following mTBI. In this study, Breath-Hold (BH) task …

A P-Adic Spectral Triple, Sumedha Hemamalee Rathnayake

Open Access Dissertations

We construct a spectral triple for the C*-algebra of continuous functions on the space of p-adic integers. On the technical level we utilize a weighted rooted tree obtained from a coarse grained approximation of the space combined with the forward derivative D on the tree. Our spectral triple satisfies the properties of a compact spectral metric space and the metric on the space of p-adic integers induced by the spectral triple is equivalent to the usual p-adic metric. Furthermore, we show that the spectrum of the operator D*D is closely related to the roots of a certain …

Simulating Depth Of Field Using Per-Pixel Linked List Buffer, Yang Liu

Open Access Theses

In this thesis, I present a method for simulating three characteristics of depth of field image: partial occlusion, bokeh and blur. Retrieving color from occluded surfaces is achieved by constructing a per-pixel linked list buffer, which only requires two render passes. Additionally, per-pixel linked list buffer eliminates the memory overhead of empty pixels in depth layers. Bokeh and blur effect are accomplished by image-space point splatting (Lee 2008). I demonstrate how point splatting can be used to account for the effect of aperture shape and intensity distribution on bokeh. Spherical aberration and chromatic aberration can be approximated using a custom …

Our novel 3D reconstruction algorithm generates realistic tree models with a good 3D polygon topology. ^ The second part of this research is a functional model of a Golden Delicious apple tree. We use our simulation framework and data collected in Purdue Meigs farm over the year 2014 to create a realistic data-driven model. The model reacts on temperature …

Teaching Introductory Game Development With Unreal Engine: Challenges, Strategies, And Experiences, Nicholas A. Head

Open Access Theses

From the days of Pong to 100 million dollar projects such as the Grand Theft Auto franchise, video games have evolved significantly over the years. This evolution has also changed the way game development is viewed as a career. Today, video games are one of the most profitable forms of entertainment, and game development courses are appearing at universities around the world. Even with this growth, a degree from a university has yet to be an important factor in finding a job in game development (Owen, 2013). This thesis examines a method of creating and implementing an introductory gaming course …

A Concept Paper On Networks Of Excellence For Research And Education, Suresh V. Garimella, David B. Janes, Anne Slaughter Andrew

PPRI Digital Library

Research and education ecosystems, foundational components of knowledge-based economies, are relatively underdeveloped in Latin America. The entire ecosystem of a research university — including resources, corporate partnerships, and research — must capitalize on a symbiosis between the research, education and commercialization missions. A university cannot transform unilaterally nor can universities sustain the required transformation without government and industry participation. Initiatives to accelerate the development of research university ecosystems are critical for the realization of knowledge-based economies and resilient civil societies.

To accelerate the development of research and education ecosystems across the Americas, the authors propose to establish “Networks of Excellence” …

Science, Values, And Power: Toward A Christian-Critical Perspective On Responsible Science, Darrin W. Snyder Belousek

Claritas: Journal of Dialogue and Culture

This essay critically examines a questionable presupposition of contemporary science—that science is an instrumental means to human ends and as such is a value-neutral project. According to this presupposition, the responsibility for the ethical evaluation of science concerns only the uses to which science is put by society and thus does not belong properly to the scientific profession. This view, which C. P. Snow called “the myth of ethical neutrality,” is critiqued along ethical, philosophical, and theological axes of analysis. Once we recognize that science is essentially a form of power, it becomes clear that science is morally ambiguous because …

Winter Weather Services And Forecasting Options For Local Agencies, Michael Baldwin

Purdue Road School

Students majoring in atmospheric science at Purdue's Department of Earth, Atmospheric, and Planetary Sciences have organized a "forecasting club" to provide weather forecasting services to a wide range of customers. During the winter months, these students provide a detailed forecast of conditions across the state of Indiana that are expected to impact road maintenance operations. These forecasts are available via a web page as well as direct email. Other information regarding winter weather observations and predictions is rapidly increasing in availability. This presentation will discuss these freely available sources of winter weather information that can be used by local agencies …

The Positive Impact Of Project-Based Learning On Attendance Of An Economically Disadvantaged Student Population: A Multiyear Study, Casey Creghan, Kathleen Adair-Creghan

Interdisciplinary Journal of Problem-Based Learning

Students who do not regularly attend high school are at an increased risk of failure in the classroom and may eventually contribute to a higher dropout rate. More specifically, the attendance rates of students from economically disadvantaged backgrounds have traditionally been lower than those with average means. Therefore, the purpose of this quantitative study was to examine the effects of a project-based learning (PjBL) environment on economically disadvantaged high school students in regard to their attendance rates. Data were collected in order to compare attendance rates of a school utilizing traditional teaching methodologies with a school using PjBL as the …

A Contribution Toward Better Understanding Of Overbanking Tendency In Fixed-Wing Aircraft, Nihad E. Daidzic

Journal of Aviation Technology and Engineering

The phenomenon of overbanking tendency for a rigid-body, fixed-wing aircraft is investigated. Overbanking tendency is defined as a spontaneous, unbalanced rolling moment that keeps increasing an airplane’s bank angle in steep turns and must be arrested by opposite aileron action. As stated by the Federal Aviation Administration, the overbanking tendency may lead to a loss of control, especially in instrument meteorological conditions. It was found in this study that the speed differential over wing halves in horizontal turns indeed creates a rolling moment that achieves maximum values for bank angles between 45 and 55 degrees. However, this induced rolling moment …

Vectors Or Constellations? Curatorial Narratives Of Latin American Art, Camila Maroja, Abigail Winograd

Artl@s Bulletin

This paper examines the curatorial visions guiding the Mercosul Biennial (1997), curated by Frederico Morais, and Inverted Utopias (2004), co-curated by Mari Carmen Ramírez and Héctor Olea. Both strove to shift the association of Latin American art with the fantastic that had dominated the region’s historiography. The structural metaphors used to frame these shows demonstrated differing aims: Morais’s desire to create an autochthonous historiography versus Ramírez and Olea’s wish to revise constructions of global modernism. Nonetheless, both exhibitions showcased similar works and helped to consolidate a revised vision of Latin American art.

Between Paris And The “Third World”: Lea Lublin’S Long 1960s, Isabel Plante

Artl@s Bulletin

Lea Lublin resided for the most part in Paris from 1964 on, and by 1965 she started orienting her work toward establishing a methodology for reading images, based on different parameters of perception and participation related to the devices involved in their exhibition. Until 1972 she articulated a considerable portion of her projects between Paris, Buenos Aires and Santiago de Chile. These networks of production and circulation were decisive in constructing the meaning of her works in terms of exploring the status of representation and culture. We propose a study that would restore the geopolitical density and translocal nature of …

Using Game-Based Learning To Foster Critical Thinking In Student Discourse, Marc I. Cicchino

Interdisciplinary Journal of Problem-Based Learning

Previous research indicates the importance of student discourse in the construction of knowledge and the fostering of critical thinking skills, especially in the field of problem-based learning (PBL). Further, a growing body of research on game-based learning (GBL) draws parallels between playing certain types of games and the solving of ill-structured problems, citing similar conditions for learning (student centered, small student groups, teachers as facilitators, problems as vehicles for development), and similar learning outcomes (communication, problem-solving, critical thinking, collaboration) as PBL. However, there is a gap in understanding how GBL affects critical thinking as embodied by student discourse when implemented …
