Some Effects of X-Irradiaion on the Adrenal Response to Hypothalamic Stimulation in Rats

Some Effects of X-Irradiaion on the Adrenal Response to Hypothalamic Stimulation in Rats

Date: January 1967
Creator: Agnew, Robert Laing
Description: Exactly where in the hypothalamus is the adrenal-pituitary response to X-irradiation "triggered" or initiated? Moreover, does ionizing radiation act directly on specific centers in the brain or does it act indirectly via the production of some humoral agents? Finally, what role does the hypothalamus play in the radiation-syndrome? The purpose of the present study was to attempt to answer these questions by determining the effects of two stressor agents, X-irradiation and electrical stimulation applied either singly or together, on the activity of the adrenal-pituitary axis. The parameters measured were changes in plasma corticosterone, in circulating eosinopihils, and in adrenal gland weight.

Nesting Ecology and Reproductive Correlates in the Desert-nesting Gray Gull Larus Modestus

Nesting Ecology and Reproductive Correlates in the Desert-nesting Gray Gull Larus Modestus

Date: May 1993
Creator: Aguilar Pulido, Roberto E. (Roberto Eric)
Description: General objectives of my study were to describe the reproductive ecology of gray gulls in the large Lealtad colony, with emphasis on demographic parameters and physiological adaptations of eggs and chicks, which would complete some original objectives established in the early 1980's by Guerra and Fitzpatrick. Specifically, my study focused on describing, then comparing with other desert and non-desert nesting larids, interactive effects of ambient physical conditions and nest-site predation on eggs and chicks.

Present tense marking as a synopsis of Southern American English: Plural verbal -s and zero 3rd singular.

Present tense marking as a synopsis of Southern American English: Plural verbal -s and zero 3rd singular.

Date: May 2005
Creator: Aguilar, Amanda G.
Description: This thesis explores the evolution plural verbal -s ("People thinks he is guilty") and zero 3rd singular ("He think he is guilty") in data from two sources on Southern English: The Linguistic Atlas of the Gulf States (LAGS) and The Linguistic Atlas of the Middle and South Atlantic States (LAMSAS). The research questions that underlie this study consider (1) the demographic association of plural verbal -s and zero 3rd singular, (2) the maintenance of each form, (3) the constraints on their use, and (4) the origins of -s variability. The atlas data suggest the following for plural verbal -s: (1) it has a British source, (2) it was present in both African American Vernacular English (AAVE) and early Southern White English (SWE), and (3) there were different grammatical constraints on its use in AAVE and SWE. Data for zero 3rd singular -s suggest this form (1) did not have a British source and (2) that it has historically been an AAVE feature.

The effect of individual versus collective creative problem solving experiences on fourth- and fifth-grade students' compositional products.

The effect of individual versus collective creative problem solving experiences on fourth- and fifth-grade students' compositional products.

Date: December 2004
Creator: Aguilar, Beatriz E.
Description: The purpose of the study was to explore the effects that individual vs. collective structured creative musical problem solving tasks had on students' compositional products. Subjects in a convenience sample of 32 fourth-graders and 32 fifth-graders were randomly assigned to either the individual or collective condition. The 3 treatment sessions were characterized by an open-ended creative problem solving task, which included questions intended to guide subjects through 3 stages of the creative problem solving process: Understanding the Problem, Generating Ideas, and Planning for Action. Subjects participated in the pre- and posttest individually. Three experienced music educators assessed the compositional products in terms of pattern use, cohesiveness, and creativity. The originally intended MANCOVAs could not be carried out because the data did not meet the necessary assumptions. Pretest and posttest scores were explored with individual ANOVAs. The Bonferroni technique was used to adjust the alpha level. The statistical analyses showed that subjects exposed to the individual condition obtained higher scores than subjects exposed to the collective condition on six of the eight explored subtests, but these differences were not significant. The level of interjudge reliability decreased at each of the three measurements of the study: pilot test, pretest, and posttest. The ...

Family Structure and Marijuana Use Among Adolescents

Family Structure and Marijuana Use Among Adolescents

Date: May 2014
Creator: Aguilar, Jamie M.
Description: Family structure as a predictive variable of juvenile delinquency has been studied for the last hundred years. This relationship originated due to societal belief that divorce was detrimental to adolescents. Due to the changing societal roles in the United States, family structure has been changing. More children are growing up in non-intact families, such as single-parent households, households with stepparents, cohabitating families, and households without a parent present. To study the effect family structure has on juvenile delinquency, researchers have utilized social control theory, differential association, self-control theory and general strain theory to conceptualize variables to explain why family structure influences delinquent behavior. A review of previous literature on this topic indicates that living in intact households, which are households with two biological parents who are married, have, on average, the lowest rates of delinquency. This thesis investigates the relationship between family structure and lifetime marijuana use among eighth and tenth grade adolescents in the United States through the use of secondary data analysis of Monitoring the Future Study, 2012. The results provide support for the relationship between family structure and lifetime marijuana use.

Interpersonal Factors Related to the Pursuit of a Higher Education Among First Generation Undergraduate Students

Interpersonal Factors Related to the Pursuit of a Higher Education Among First Generation Undergraduate Students

Date: May 2012
Creator: Aguirre, Jacqueline S.
Description: The typical educational stressors experienced by college students, in conjunction with developmental stressors such as separation from parents, individuation, and perceived social support, can interact to impact adaptation significantly. First generation college students (students who are the first in their family to attend college) can experience stressors beyond the typical educational stressors experienced by later generation college students, including lack of support from family and peers as well as financial difficulties that can interact to impact the pursuit of an education beyond the undergraduate level. The present study examined factors that may be especially influential in the pursuit of a higher education for first generation college students. Results indicated that aspects of family enmeshment were related to academic motivation for first generation students, but not for later generation students. Exploratory analysis showed that family and finances were mentioned more often among first generation students when compared to later generation students as stressors that strongly influence the desire to continue beyond the undergraduate level.

Refactoring FrameNet for Efficient Relational Queries

Refactoring FrameNet for Efficient Relational Queries

Date: December 2003
Creator: Ahmad, Zeeshan Asim
Description: The FrameNet database is being used in a variety of NLP research and applications such as word sense disambiguation, machine translation, information extraction and question answering. The database is currently available in XML format. The XML database though a wholesome way of distributing data in its entireness, is not practical for use unless converted to a more application friendly database. In light of this we have successfully converted the XML database to a relational MySQL™ database. This conversion reduced the amount of data storage amount to less than half. Most importantly the new database enables us to perform fast complex querying and facilitates use by applications and research. We show the steps taken to ensure relational integrity of the data during the refactoring process and a simple demo application demonstrating ease of use.
