Faculty use of the World Wide Web: Modeling information seeking behavior in a digital environment

Faculty use of the World Wide Web: Modeling information seeking behavior in a digital environment

Date: December 2000
Creator: Fortin, Maurice G.
Description: There has been a long history of studying library users and their information seeking behaviors and activities. Researchers developed models to better understand these information seeking behaviors and activities of users. Most of these models were developed before the onset of the Internet. This research project studied faculty members' use of and their information seeking behaviors and activities on the Internet at Angelo State University, a Master's I institution. Using both a quantitative and qualitative methodology, differences were found between tenured and tenure-track faculty members on the perceived value of the Internet to meet their research and classroom information needs. Similar differences were also found among faculty members in the broad discipline areas of the humanities, social sciences, and sciences. Tenure-track faculty members reported a higher average Internet use per week than tenured faculty members. Based on in-depth, semi-structured interviews with seven tenured and seven tenure-track faculty members, an Internet Information Seeking Activities Model was developed to describe the information seeking activities on the Internet by faculty members at Angelo State University. The model consisted of four basic stages of activities: "Gathering," "Validating," "Linking" with a sub-stage of "Re-validating," and "Monitoring." There were two parallel stages included in the model. ...

Feigning cognitive deficits on neuropsychological evaluations: Multiple detection strategies

Feigning cognitive deficits on neuropsychological evaluations: Multiple detection strategies

Date: December 2000
Creator: Bender, Scott D.
Description: Individuals undergoing forensic neuropsychological evaluation frequently stand to gain in some manner if neurocognitive dysfunction is diagnosed. As a result, neuropsychologists are customarily asked to test for neurocognitive feigning during the assessment. The current study employed an analogue design with a clinical comparison group to examine the utility of the TOCA (Rogers, 1996) as a measure of feigned neurocognitive impairment. Two groups of simulators (one cautioned about the presence of detection strategies and one not cautioned) were compared to clinical and normal control groups. Fourteen scales were developed based on five detection strategies: symptom validity testing, performance curve, magnitude of error, response time, and floor effect. Each was employed during both verbal and nonverbal tasks. Significant differences were revealed among groups when subjected to ANOVA. Classification rates from subsequent utility estimates and discriminant function analyses on the scales ranged from 58.8% to 100%. Combining strategies yielded a classification rate of 95.7%. The effect of cautioning simulators was modest; however, a trend was noted on some scales for cautioned simulators to appear less obviously impaired than noncautioned. Although the results require crossvalidation, preliminary data suggest that the TOCA is a sensitive and specific measure of feigned neurocognitive performance. Strengths and weaknesses ...

The four major education GI Bills: A historical study of the shifting national purposes and accompanying changes in economic value to veterans.

The four major education GI Bills: A historical study of the shifting national purposes and accompanying changes in economic value to veterans.

Date: December 2000
Creator: Spaulding, Donald James
Description: Benefits for soldiers follow the formation of ancient and present day armies raised for the purpose of extending the national or state will. Veterans' benefits for defenders of the U.S. emerged during the American colonial period. College benefits began after WWII with the GI Bill of Rights. This study examines the variations in purpose for nationally established educational benefits for veterans and the singular value to the veterans of these 5educational benefits. The study begins with an overview of the history of veterans' benefits. Primary emphasis is then placed on the educational portion of the World War II Servicemen's Readjustment Act and the current educational benefit, the Montgomery GI Bill. As the purpose of awarding educational benefits changed from World War II to the latest U.S. war, the Gulf War of 1990-1991, the economic value to the individual veteran also changed. The WWII GI Bill featured an educational provision intended to keep returning veterans out of the changing economy whereas current GI Bills is intended as a recruiting incentive for an all-volunteer force. Correspondingly, the economic value to the individual veteran has changed. Data supporting this study were extracted from historical documents in primary and secondary scholarly studies and writings, ...

Haiku Seasons

Haiku Seasons

Date: December 2000
Creator: Smith, Steven Lyle
Description: Haiku Seasons is a choral work that uses several haiku to portray moments in nature. Spread throughout the performance space, four choirs (SATB, 3/part) depict larger parts of the pastoral scene (i.e., mountains, the moon, etc.). Soloists depart from the choirs in order to perform solo, duo, trio, and quartet passages, which take place throughout the work. If enough singers are available, individual soloists may be used. The soloist groups display the more intimate moments of the scenes (i.e., sparrows, a blade of grass, etc.). The intent of Haiku Seasons is to create an image of nature isolated from human interaction. Thus, the image is a pastoral setting with many independent parts all coexisting in a relatively silent world. I combine aspects of tonality, time, space, and silence to create this image.

Happiness Is a By-Product of Function: William Burroughs and the American Pragmatist Tradition

Happiness Is a By-Product of Function: William Burroughs and the American Pragmatist Tradition

Date: December 2000
Creator: Goeman, James Robert
Description: This dissertation examines the techniques and themes of William Burroughs by placing him in the American Pragmatist tradition. Chapter One presents a pragmatic critical approach to literature based on Richard Rorty and John Dewey, focusing on the primacy of narration over argumentation, redescription and dialectic, the importance of texts as experiences, the end-products of textual experiences, and the role of critic as guide to experience rather than judge. Chapter Two uses this pragmatic critical lens to focus on the writing techniques of William Burroughs as a part of the American Pragmatist tradition, with most of the focus on his controversial cut-up technique. Burroughs is a writer who upsets many of the traditional expectations of the literary writing community, just as Rorty challenges the conventions of the philosophical discourse community. Chapter Three places Burroughs within a liberal democratic tradition with respect to Rorty and John Stuart Mill. Burroughs is a champion of individual liberty; this chapter shows how Burroughs' works are meant to edify readers about the social, political, biological, and technological systems which work to control individuals and limit their liberties and understandings. The chapter also shows how Burroughs' works help liberate readers from all control systems, and examines the ...

Hard and Soft

Hard and Soft

Date: December 2000
Creator: Gray, J. Christensen
Description: The purpose of this investigation is to explore the possibilities of manipulating clay in three distinct ways to effectively show that clay objects were at one time moist and pliable. The techniques used are faceting while wet, manipulating a variety of additions, applying different glazing techniques, and three separate firing methods. In addressing the problem, the following concerns were considered: (a) Which of the pieces made best expresses my aesthetic concerns? (b) Which firing method, oxidation, reduction or atmospheric, best illustrates these concerns? (c) Which glazing technique was most successful? In an attempt to explore and solve these problems, a series of twenty pieces were produced. A visual record of slides showing individual pieces were made to demonstrate the differences and similarities between firing methods.

Head trauma release of histamine from dural mast cells alters blood-brain barrier: attenuation with Zolantidine

Head trauma release of histamine from dural mast cells alters blood-brain barrier: attenuation with Zolantidine

Date: December 2000
Creator: Laufer, Susan R.
Description: This study employed a new model of mild-to-moderate head trauma to specifically identify the role of dural mast cell (MC) histamine in trauma-induced increased permeability in the blood-brain barrier (BBB). A single line was scored partially through the left dorsal parietal skull. Immediately following the trauma, degranulation was seen in 39% of the MCs on the left and in 2% on the right. After a 20 min survival period, left duras showed 55% with MC degranulation (fewer with complete degranulation) compared to 34% on the right. In the other experiments two parallel lines were scored following the injection of Evan's blue. Histamine assay showed histamine increased in the left cortex to 154% at 5 min, 174% at 10 min, and 151% at 20 min. Fluorescent quantitation of extravasated Evan's blue at 20 min following the trauma gave an increase of 1385% over the value measured for the right cortex. Zolantidine, a selective histamine H2 receptor antagonist, administered at 10- and 20- mg/kg 30 min before the trauma blocked 65% of the Evan's blue extravasation compared with the control and 2.5 mg group.

High-temperature corrosion of aluminum alloys: Oxide-alloy interactions and sulfur interface chemistry

High-temperature corrosion of aluminum alloys: Oxide-alloy interactions and sulfur interface chemistry

Date: December 2000
Creator: Addepalli, Swarnagowri
Description: The spallation of aluminum, chromium, and iron oxide scales is a chronic problem that critically impacts technological applications like aerospace, power plant operation, catalysis, petrochemical industry, and the fabrication of composite materials. The presence of interfacial impurities, mainly sulfur, has been reported to accelerate spallation, thereby promoting the high-temperature corrosion of metals and alloys. The precise mechanism for sulfur-induced destruction of oxides, however, is ambiguous. The objective of the present research is to elucidate the microscopic mechanism for the high-temperature corrosion of aluminum alloys in the presence of sulfur. Auger electron spectroscopy (AES), low energy electron diffraction (LEED), and scanning tunneling microscopy (STM) studies were conducted under ultrahigh vacuum (UHV) conditions on oxidized sulfur-free and sulfur-modified Al/Fe and Ni3Al(111). Evaporative deposition of aluminum onto a sulfur-covered iron surface results in the insertion of aluminum between the sulfur adlayer and the substrate, producing an Fe-Al-S interface. Aluminum oxidation at 300 K is retarded in the presence of sulfur. Oxide destabilization, and the formation of metallic aluminum are observed at temperatures > 600 K when sulfur is located at the Al2O3-Fe interface, while the sulfur-free interface is stable up to 900 K. In contrast, the thermal stability (up to at least 1100 ...

The Impact of Conservative Protestantism Upon The Time Fathers Spend With Their Children

The Impact of Conservative Protestantism Upon The Time Fathers Spend With Their Children

Date: December 2000
Creator: Miller, Mark Sheldon
Description: This research was concerned with the possible effects that religion, especially conservative Protestantism, has upon the performance of fatherhood. The influence of religion was assessed using the religious beliefs reported by fathers. The performance of fatherhood focused on the amount of time fathers spent meeting the physical needs of their young children. This research hypothesized that conservative Protestant fathers would spend more time meeting their children's physical needs than other Protestant fathers. Also hypothesized was that the level of conservative Protestant beliefs held by fathers is positively related to the proportion of time they spent meeting the physical needs of their children out of the total time spent by fathers and mothers combined. Finally, it was hypothesized that the level of conservative Protestant beliefs held by fathers was positively related to their membership in conservative religious denominations. In order to test whether conservative Protestantism has an effect upon the amount of time that fathers spend meeting the physical needs of their young children, this study will used data from the first wave of the National Survey of Families and Households (NSFH), completed in 1988. Regression analysis was used to test the first two hypotheses and crosstabulation analysis was used to ...

Intentions and Implementation of the Professional Development and Appraisal System in Texas

Intentions and Implementation of the Professional Development and Appraisal System in Texas

Date: December 2000
Creator: Davis-Frost, Diane
Description: The purpose of this study was to describe the intentions of the designers of the Professional Development and Appraisal System (PDAS) in Texas and the perceptions of teachers regarding its implementation. Information for the study was gathered in two phases using two methodologies. The first was a semi-structured interview with four expert informants instrumental in the design and implementation of the PDAS at the state level. The second component of the study was conducted with teachers using a 37-item Likert survey. The population for this phase of the study was 150 elementary and 150 secondary teachers chosen randomly from three school districts in North Central Texas. The districts were selected to represent a variety of sizes in regard to student population and represent diverse student population characteristics and socioeconomic levels. Data from the semi-structured interviews and the returned surveys were analyzed to determine the designers' intentions and areas of emphasis and to describe the alignment the teachers' perceptions and the designers' intentions. Quantitative data gathered from the surveys were analyzed using descriptive statistics as well as a correlation and function analysis and analysis based on a Cronbach alpha coefficient. The analysis of data revealed the following: 1. Teachers perceived that ...
