Neuroimmunoendocrine Pathology And Cognitive Function In Type 2 Diabetes, Krista Wild Dec 2007

Neuroimmunoendocrine Pathology And Cognitive Function In Type 2 Diabetes, Krista Wild

Psychology Dissertations

Cognitive impairment among older adults with type 2 diabetes may worsen health outcomes via negative impact on compliance with medical self-care recommendations. Results of several previous studies indicate that cognitive deficits are present in older European American adults with type 2 diabetes under some conditions, particularly related to glucose dysregulation (as evidenced by high glycated hemoglobin, i.e., HbA1c). Despite the fact African Americans are disproportionately affected by diabetes and suffer significantly greater numbers of complications and more severe complications relative to European Americans, no published studies have examined cognitive functioning among older African American adults with type 2 diabetes. Further, …


Examining The Distinction And Concordance Between Implicit Measures Of Alcohol Expectancies: Toward Agreement On Their Meaning And Use, Maureen C. Below Aug 2007

Examining The Distinction And Concordance Between Implicit Measures Of Alcohol Expectancies: Toward Agreement On Their Meaning And Use, Maureen C. Below

USF Tampa Graduate Theses and Dissertations

Alcohol expectancies have traditionally been measured with explicit self-report questionnaires, but in recent years implicit measures have also been used to explore the tenets of expectancy theory. The basic psychometric properties of reliability and validity have not been established for most implicit tasks, and the convergent validity of different implicit measures has not been explored. Despite these shortcomings, many researchers continue to treat implicit tasks as reliable and valid assessment tools. To address reliability and validity of implicit measures, 218 undergraduate women and men were recruited from the University of South Florida to examine the psychometric properties of and concordance …


The Impact Of Variable Data Print On Usability In Design, William Wells Jun 2007

The Impact Of Variable Data Print On Usability In Design, William Wells

Theses

In a world where people see, process and remember information differently, the question arises: Is technology being used in a manner that acknowledges and addresses user differences to the fullest extent? Currently, new print technologies like Variable Data Printing (VDP) are only being used to create customized direct mailing pieces and personalized products for the purpose of marketing, sales and promotion. However, VDP introduces the ability to change data and design elements in printed documents on an individual basis, making it possible to address differences in visual and cognitive abilities, language and culture, and situational considerations. Applying this concept of …


The Effects Of Early Postnatal Pcp Administration On Performance In Locomotor Activity, Reference Memory, And Working Memory Tasks In C57bl/6 Mice, Alan L. Pehrson Jan 2007

The Effects Of Early Postnatal Pcp Administration On Performance In Locomotor Activity, Reference Memory, And Working Memory Tasks In C57bl/6 Mice, Alan L. Pehrson

Theses and Dissertations

There is a growing consensus, based on several converging lines of evidence, which suggests schizophrenia is the product of a developmental insult occurring in the late 2 nd or early 3 rd trimester. Additionally, it has been observed that adults who abuse the noncompetitive NMDA antagonist PCP present with symptoms that mimic schizophrenia, such as hallucinations, formal thought disorder, delusions, unstable or flattened affect, social withdrawal, and impaired cognition. Thus, several labs have attempted to use early postnatal PCP administration in rodents as a drug model of schizophrenia. The current study investigated the cognitive effects of early postnatal PCP administration …


Development And Validation Of The Facial Affect Learning And Memory Test (Falmt) And Facial Identification Of Affect Task (Fiat), Christina Marie Armstrong Jan 2007

Development And Validation Of The Facial Affect Learning And Memory Test (Falmt) And Facial Identification Of Affect Task (Fiat), Christina Marie Armstrong

UNLV Retrospective Theses & Dissertations

The neurocognitive assessment of visuospatial memory has begun to receive attention and has been recognized as being important in the understanding of overall memory processing. Additionally, there has been an increased emphasis on emotion processing, particularly affect discrimination and attention bias. However, little information is currently available on learning and memory for emotional information. Because emotion is expressed to a large extent through nonverbal means, a nonverbal test of emotion learning would be valuable, although no such test currently exists. The aim of the current study was to establish normative performance characteristics, convergent and divergent validity for two newly developed …


Physics Based Modeling Of The Charging Dynamics In Silicon Nanocrystal Non-Volatile Flash Memory Cell, Pavan Kumar Singaraju Venkata Sai Jan 2007

Physics Based Modeling Of The Charging Dynamics In Silicon Nanocrystal Non-Volatile Flash Memory Cell, Pavan Kumar Singaraju Venkata Sai

UNLV Retrospective Theses & Dissertations

Flash memory devices based on continuous floating gate are rapidly approaching their technological limitations due to excessive gate leakage currents, resulting from reduced tunnel oxide thickness. A new architecture based on Si-Nanocrystal floating gate has shown promise through realization of devices with reduced gate leakage current and lower programming and erase voltages. The dominant transport mechanisms in this device are tunneling of electrons from the (3-D) silicon into the (0-D) nanocrystals and Fowler-Nordheim tunneling of carriers from nanocrystals to the bulk Si. In order to accurately model the charging dynamics of such devices, size based quantum confinement effects should be …


The Effect Of Concomitant Ecstasy-Marijuana Use On Auditory Verbal Learning And Memory Performance, Kimberly M Cramer Jan 2007

The Effect Of Concomitant Ecstasy-Marijuana Use On Auditory Verbal Learning And Memory Performance, Kimberly M Cramer

UNLV Retrospective Theses & Dissertations

Previous research indicates that ecstasy users exhibit deficits of verbal learning and memory. This research has not considered polydrug use in ecstasy users, especially marijuana. Marijuana is an important confound because 90 percent of ecstasy users also use marijuana. Several studies have suggested that marijuana use alters verbal memory functioning; consequently, it is difficult to ascertain whether the observed memory deficits in ecstasy users are attributable to ecstasy, marijuana, or other drug use. The present study examined the effects of marijuana and ecstasy on verbal memory function. Marijuana use was accounted for by recruiting concurrent ecstasy-marijuana users' and ecstasy-naive marijuana-only …


Cognitive Mechanisms Of Memory Impairment Following Traumatic Brain Injury, Mark D. Whiting Jan 2007

Cognitive Mechanisms Of Memory Impairment Following Traumatic Brain Injury, Mark D. Whiting

Theses and Dissertations

Memory impairment is common following traumatic brain injury (TBI). In recent years, researchers have demonstrated that the processes underlying memory formation (working memory, encoding, consolidation, and retrieval) are interrelated but dissociable events.The following study was designed to determine how these processes contribute to memory impairment following experimental TBI in the rat. Experiment 1 indicated thatTBI induces severe working memory deficits in a delayed non-matching-to-place task.Although all animals displayed intact acquisition, only injured animals displayed poor performance as the delay between the sample and choice phases was increased.Experiment 2 was designed to determine if TBI produces a transient period of posttraumatic …

Gendered Struggle For The Freedom From Violence Using Frantz Fanon’S Theory In Three Postcolonial Novels: Albert Wendt’S Pouliuli, Tsitsi Dangarembga’S Nervous Conditions, And Edwidge Danticat’S Breath, Eyes, Memory, Robin M. Respaut Jan 2007

Gendered Struggle For The Freedom From Violence Using Frantz Fanon’S Theory In Three Postcolonial Novels: Albert Wendt’S Pouliuli, Tsitsi Dangarembga’S Nervous Conditions, And Edwidge Danticat’S Breath, Eyes, Memory, Robin M. Respaut

Honors Theses

While studying abroad in New Zealand last year, I became intrigued by Albert Wendt’s novel Pouliuli, because it was my first literary view into Pacific Island culture. My interest in the novel was part of my awakening to the particular damage done by the west in Oceania. By attending classes on the anthropology and sociology of postcolonial Pacific societies, I discovered how the west had acted in the region to encourage progressive technology in ways that handled native traditional culture with unconscious disrespect. I was stunned to learn that Oceania is the most aided region in the world today, surpassing …
