The Response of Aquatic Insect Communities and Caged In situ Asiatic Clams (Corbicula fluminea) to Dechlorinated Municipal Effluent in the Trinity River in North Texas

Description: Dischargers to the Trinity River in North Texas were required to dechlorinate their effluents in 1990-91. Field surveys were conducted above and below an outfall to determine the response of resident immature insects and caged in situ juvenile Asiatic clams to chlorinated and dechlorinated effluent. Within six months after dechlorination began, insect community composition and C. fluminea survival significantly improved at stations below the outfall. Significantly lower clam growth within one m… more

Martin Scorsese, Quentin Tarantino, and the Crime Films of the Nineteen Nineties

Description: Martin Scorsese's films, GOODFELLAS and CASINO, and Quentin Tarantino's RESERVOIR DOGS and PULP FICTION are examined to determine if the crime film of the 1990s has become increasingly more in the style of film noir. The differences and similarities between the two crime films each director has either written or co-written in the 1990s are delineated to demonstrate this trend. Other crime films of the latter 1990s (SEVEN, THE USUAL SUSPECTS, and MULHOLLAND FALLS) are also examined to aid in def… more

Biochemical Identification of Molecular Components Required for Cyanide Assimilation in Pseudomonas fluorescens NCIMB 11764

Description: Utilization of cyanide as a nutritional nitrogen source in P. fluorescens NCIMB 11764 was shown to involve a novel metabolic mechanism involving nonenzymatic neutralization outside of cells prior to further enzymatic oxidation within. Several cyanide degrading enzymes were produced by NCIMB 11764 in response to growth or exposure to cyanide, but only one of these cyanide, oxygenase (CNO), was shown to be physiologically required for assimilation of cyanide as a growth substrate.

Self-Efficacy and Selected Variables as Predictors of Persistence for First Quarter Students at a Proprietary Institution

Description: Proprietary colleges are uniquely different from two or four year colleges due to the emphasis on the student establishing a definite career path prior to enrollment. Because of this career track emphasis, Bandura's (1977) postulation that self-efficacy is a significant variable influencing task completion may offer insight into the challenge of student retention at a proprietary college. The study's purpose was to determine if career self-efficacy, demographic factors, and academic preparednes… more

Continuous, Nowhere-Differentiable Functions with no Finite or Infinite One-Sided Derivative Anywhere

Description: In this paper, we study continuous functions with no finite or infinite one-sided derivative anywhere. In 1925, A. S. Beskovitch published an example of such a function. Since then we call them Beskovitch functions. This construction is presented in chapter 2, The example was simple enough to clear the doubts about the existence of Besicovitch functions. In 1932, S. Saks showed that the set of Besicovitch functions is only a meager set in C[0,1]. Thus the Baire category method for showing the e… more

A Theory of the Role of Medium of Exchange in Mergers and Acquisitions

Description: An acquisition bid is like any other proposal for risky investment. The difference arises due to additional source of risk arising from two different sources of information asymmetry due to private knowledge held by the bidder and target. We hypothesize that the bidding process evolves in a manner to optimize bidder's investment in the target through a process of joint signalling. Medium of exchange and bid premium are used as the two signal elements simultaneously by the bidder. We develop a m… more

Predicting the Retirement Intentions of Professional Workers

Description: While research focusing on the retirement intentions of individuals within the general population has been undertaken, only two empirical studies have examined the retirement intentions of professional workers. This study expands the small, existing body of literature focusing on this topic by presenting eighteen hypotheses, grouped into five categories of factors, and testing them with the National Longitudinal Surveys of Labor Market Experience.

Posttraumatic Stress Disorder as a Differential Diagnosis of Sexually Abused Children: a Survey of Psychologists

Description: Psychologists' diagnostic choices when the specificity of child sexual abuse in a clinical vignette is varied was examined. The degree to which Posttraumatic Stress Disorder (PTSD) was judged to be a viable diagnostic choice among a set of diagnoses was analyzed under conditions with sexual abuse stated, implied, not stated, and excluded. PTSD was rated as more likely for the stated and implied sexual abuse vignettes than for the not stated and excluded vignettes.

A Comparison of At-Risk Students Receiving an Academic Support Program with At-Risk Students Receiving no Academic Support Program

Description: The problem of this study was to determine if at-risk students who were enrolled in an educational support class for one hour a day would have an improvement on the four at-risk indicators being measured over students not enrolled in the academic support program. The four at-risk indicators are grade point average, self-concept, days absent from school, and discipline referrals. The hypothesis formulated for this study predicted no significant difference in mean scores of the four measured indi… more

Primitive Substitutive Numbers are Closed under Rational Multiplication

Description: Lehr (1991) proved that, if M(q, r) denotes the set of real numbers whose expansion in base-r is q-automatic i.e., is recognized by an automaton A = (Aq, Ar, ao, δ, φ) (or is the image under a letter to letter morphism of a fixed point of a substitution of constant length q) then M(q, r) is closed under addition and rational multiplication. Similarly if we let M(r) denote the set of real numbers α whose base-r digit expansion is ultimately primitive substitutive, i.e., contains a tail which is … more
