Floods and Drought, USGCRP Seminar, 8 May 1995. (open access)

Floods and Drought, USGCRP Seminar, 8 May 1995.

In this USGCRP seminar, issues about the impact of drought and floods in the news and feel it in the cost of goods and services would be discussed. Each year seems to bring with it droughts or floods that cause billions of dollars in economic losses and untold societal disruption to major parts of our nation. (Drought in the Midwest in 1988 and in the Southeast in 1989. Floods in the Mississippi River Basin in 1992 and in California in 1994). Around the world the situation is the same, even worse in some instances. What causes these extreme events and conditions? Can we predict the occurrence of such events as a means of being prepared, and reducing the impacts of extreme climate events? Can we be better prepared? What success to date has there been in predicting such events? What's the prognosis?

Small Business Owner-Managers and Corporate Managers: a Comparative Study of Achievement Motivation, Risk Taking Propensity and Preference for Innovation (open access)

Small Business Owner-Managers and Corporate Managers: a Comparative Study of Achievement Motivation, Risk Taking Propensity and Preference for Innovation

Despite the economic significance of entrepreneurship, relatively little is known about the entrepreneur, particularly how the entrepreneur differs from the corporate manager. This problem is both cause and symptom of the discord regarding definitions of the entrepreneur, rendering sampling, research replication and generalizations about entrepreneurs problematic. As a result, inquiry has failed to adequately establish how entrepreneurs differ from managers, a problem partially stemming from a dearth of methodologically rigorous comparisons of entrepreneurs with managers. The primary purpose of this study was to investigate the potential of psychological constructs to predict a proclivity for entrepreneurship. Moreover, differences in types of small business owner-managers were also investigated. Included in the research model were three common themes in the entrepreneurship literature: achievement motivation, risk taking propensity and preference for innovation. Also incorporated were the interactions of the psychological constructs, as well as individual and firm demographic variables.

Women's and Men's Perceptions Regarding Perceived Speaker Sex and Politeness of Given Utterances (open access)

Women's and Men's Perceptions Regarding Perceived Speaker Sex and Politeness of Given Utterances

Women's and men's responses regarding perceived speaker sex and the politeness of given utterances were examined through the use of a questionnaire administered to 90 people, 45 men and 45 women. The questionnaire required respondents to rate the politeness of each utterance and label each as being more likely spoken by a man or by a woman. Factors possibly affecting perceptions--such as power, prestige, and the stereotypical conversational structures of both men and women--were addressed through others' research in this area. Additionally, all tested sentences were analyzed in light of linguistic politeness theory regarding on-record and off-record speech. This analysis details each utterance through examining the type of politeness strategy each utterance typifies.

An Investigation into the Stability of Students' Timbre Preferences from the Sixth through the Tenth Grade (open access)

An Investigation into the Stability of Students' Timbre Preferences from the Sixth through the Tenth Grade

The purpose of the study was to determine whether students' timbre preferences in the sixth grade remain stable through the tenth grade. The investigation also examined whether gender, band instruction, or musical home environment makes any difference in influencing the stability of students' timbre preferences from grade six through ten. Students' timbre preferences at the beginning of the study were compared to their preferences four years later. The students' timbre preferences were obtained by employing Gordon's Instrument Timbre Preference Test (ITPT). A questionnaire was also utilized at the conclusion of the study to determine which students had musical home environments and which did not. All sixth grade students enrolled in a single school district took the ITPT. Each student's scores were tallied and ranked in order to determine their timbre preferences; four years later they were retested and their scores were ranked again.

A Criterion Validity Study of the MMPI-2 and PAI Spanish Versions with DIS Diagnosis: Implications for Clinical Practice (open access)

A Criterion Validity Study of the MMPI-2 and PAI Spanish Versions with DIS Diagnosis: Implications for Clinical Practice

New Spanish versions of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) and the Personality Assessment Inventory (PAI) were assessed with the Spanish translation of the Diagnostic Interview Schedule (DIS) as the gold standard. Findings from categorical and dimensional analyses suggest that, although the degree of diagnostic concordance of both measures with the DIS was found to be moderately high, the MMPI-2 clinical scales yielded greater specificity but lower sensitivity than the PAI scales on two of four diagnostic categories (i.e., Major Depression, and Schizophrenia). Both measures failed to correctly diagnose Anxiety Disorders, while the MMPI-2 also showed poor diagnostic accuracy with Alcohol Dependence.

An Evaluation of Fish and Macroinvertebrate Response to Effluent Dechlorination in Pecan Creek (open access)

An Evaluation of Fish and Macroinvertebrate Response to Effluent Dechlorination in Pecan Creek

This study evaluated the effects of chlorinated effluent discharged from the City of Denton, Texas' wastewater treatment plant on Pecan Creek's fish and macroinvertebrate assemblages, and their recovery upon dechlorination. A baseline of ecological conditions was established while chlorine was present in the effluent (June 1993- October 1993), and was evaluated again after dechlorination with sulfur dioxide (October 1993-August 1994). In situ Asiatic clam and fathead minnow ambient toxicity tests, and fish and macroinvertebrate collections were used to establish this baseline for comparison to post-dechlorination results.

Black Nationalism Reinterpreted (open access)

Black Nationalism Reinterpreted

Black nationalism responded to America's failure to examine the effects of slavery's legacy. Its aims represent those issues that were either unsupported by or in opposition to the goals of the civil rights leadership. In particular, the civil rights movement dismissed any claims that the history of slavery had a lasting effect on African-Americans. This conflict developed because of mainstream America's inability to realize that the black community is not monolithic and African-Americans were differentially affected by slavery's legacy. It is those blacks who are most affected by the culture of poverty created by America's history of slavery who make up today's inner-city populations. Despite successes by the civil rights movement, problems within lower-class black communities continue because the issues of the black underclass have not yet been fully addressed.

Regulation of Escherichia coli pyrBI Gene Expression in Pseudomonas fluorescens (open access)

Regulation of Escherichia coli pyrBI Gene Expression in Pseudomonas fluorescens

Pseudomonas fluorescens does not appear to regulate the enzymes of de novo pyrimidine biosynthesis at the level of gene expression. Little or no apparent repression of pyr gene expression is observed upon addition of exogenous pyrimidines to the growth medium. The Escherichia coli pyrBI genes for aspartate transcarbamoylase (ATCase) were sized down and cloned into the broad host range plasmid, pKT230. Upon introduction into a P.fluorescenspyrB mutant strain, ATCase showed repression in response to exogenously fed pyrimidine compounds. Thus, it was possible to bring about changes in pyrimidine nucleotide pool levels and in transcriptional regulation of gene expression at the same time.

Enacting Racism: Clarence Thomas, George Bush, and the Construction of Social Reality

This study analyzes the confirmation hearings discourse of Clarence Thomas and George Bush. Language constructs social reality. The United States has a history of racism and this history manifests itself in our language. The discourse of Clarence Thomas and George Bush created a social reality that equated opposition to Thomas' confirmation with racism using rhetorical strategies that included metaphor and narrative construction.

US-Japan Relations during the Korean War (open access)

US-Japan Relations during the Korean War

During the Korean War, US-Japan relations changed dramatically from the occupation status into one of a security partnership in Asia. When North Korea invaded South Korea, Washington perceived Japan as the ultimate target. Washington immediately intervened in the Korean peninsula to protect the South on behalf of Japanese security. Japanese security was the most important objective of American policy regarding the Korean War, a reality to which historians have not given legitimate attention. While fighting in Korea, Washington decided to conclude an early peace treaty with Japan to initiate Japanese rearmament. The issue of Japanese rearmament was a focal point in the Japanese peace negotiation. Washington pressed Japan to rearm rapidly, but Tokyo stubbornly opposed. Under pressure from Washington, the Japanese government established the National Police Reserve and had to expand its military forces during the war. When the Korean War ceased in July 1953, Japanese armed forces numbered about 180,000 men. The Korean War also brought a fundamental change to Japanese economic and diplomatic relations in Asia. With a trade embargo on China following the unexpected Chinese intervention in Korea, Washington wanted to forbid Sino-Japanese trade completely. In addition, Washington pressed Tokyo to recognize the Nationalist regime in Taiwan …

Effects of Ten Weeks of Deep Water Running or Land Based Run Training (open access)

Effects of Ten Weeks of Deep Water Running or Land Based Run Training

Populations that utilize deep water running (DWR) are described in Chapter I. A review of the literature concerning studies comparing peak physiological variables of water exercises (swimming, DWR, & land based running) to land based exercises (cycle ergometer, walking, & running) are presented in Chapter II. The protocols utilized for obtaining peak values on land and in the water along with subject characteristics, statistical methods and description of the training regimen are discussed in Chapter HI. The results, presented in Chapter IV, indicate no interaction between any of the variables measured but a main effect for treadmill V02 peak for the pre- and post testing. Chapter V discusses factors which may limit physiological changes within each training group. Chapter VI contains suggestions for further research.

Molecular Modeling Study of Oxidative Degradation of Polyperfluoroethers Catalyzed by Iron Fluoride Surfaces : An Extended Hückel Theory Approach (open access)

Molecular Modeling Study of Oxidative Degradation of Polyperfluoroethers Catalyzed by Iron Fluoride Surfaces : An Extended Hückel Theory Approach

Extended Hückel methods are known to be a useful tool in understanding surface phenomena. Important quantities about atoms and chemical bonds can be obtained from this computationally simple method, although caution must be exercised in interpreting the results. Application of Extended Hückel calculations to large metal clusters reveals the role of d orbitals in solids. Basic ideas of constructing model compounds have been developed. Several model systems for surface chemisorption processes are constructed in order to understand the surface catalyzed oxidative degradation of polyperfluoroethers. The activation of oxygen molecules can be explained. The Lewis acid character of the iron fluoride surface can be predicted. Based on these results, mechanisms of the degradation processes are discussed.

Melville's Vision of Society : A Study of the Paradoxical Interrelations in Melville's Major Novels (open access)

Melville's Vision of Society : A Study of the Paradoxical Interrelations in Melville's Major Novels

I hold that Melvillean society consists of paradoxical relationships between civilization and barbarianism, evil and good, the corrupt and the natural, the individual and the collective, and the primitive and the advanced. Because these terms are arbitrary and, in the context of the novels, somewhat interchangeable, I explore Melville's thoughts as those emerge in the following groups of novels: Typee, Omoo, and White-Jacket demonstrate the paradox of Melvillean society; Redburn, Moby-Dick, and Mardi illustrate the corrupting effects of capitalism and individualism; and The Confidence-Man, Israel Potter, and Pierre depict a collapsed paradox and the disintegration of Melville's society.
