(4+2)-Cycloaddition Reactions of Ketenes; Pyranones

Description: This study deals with the (4+2)-cycloaddition reactions of 4-π electron compounds with ketenes. Chloroketenes were generated in situ from the corresponding chlorinated acid chlorides in the presence of the ketenophiles. Chloro-, dichloro- and diphenylketenes reacted with 1-methoxy-3-trimethylsiloxy-l,3-butadiene, and 2,4-bis(trimethylsiloxy)-1,3-pentadiene to yield the corresponding dihydropyrans. The dihydropyrans yielded substituted 4-pyranones on hydrolysis.

Ability Grouping in College Beginning Media Writing Classes

Description: The problem with which this investigation is concerned is that students of unequal writing ability are frequently placed in the same beginning media writing classes in college journalism. It is difficult for a teacher to be effective when the ability of the students ranges from those who cannot write clear complete sentences to others whose work already appears in newspapers and magazines. The purpose of this study is to determine whether students who are ability grouped into slow—average and a… more

Absorption, Relaxation, and Imagery Instruction Effects on Thermal Imagery Experience and Finger Temperature

Description: A skill instruction technique based on cognitive behavioral principles was applied to thermal imagery to determine if it could enhance either subjective or physiological responsiveness. The effects of imagery instruction were compared with the effects of muscle relaxation on imagery vividness, thermal imagery involvement, and the finger temperature response. The subjects were 39 male and 29 female volunteers from a minimum security federal prison. The personality characteristic of absorption w… more

Academic Achievement and the Ability of Post-Secondary Students to Read Assigned Materials

Description: This study provides a rationale for adopting course materials. It demonstrates the relationship between ability to read assigned materials and academic achievement, and that selection of materials creates two groups having different probabilities of success. The sample was selected from a population of all students enrolled in Principles of Economics courses at North Texas State University in the spring semester of 1986. The Nelson-Denny Reading Test was used to determine reading ability. Assig… more

Academic Task Structures in High-Ability and Average-Ability Classes

Description: This study developed propositions concerning the nature of academic tasks as they are experienced in classrooms. Specifically, the purpose of this study was to analyze academic task structures in two language-arts classes, one designated as average-ability and one designated as high-ability. Few studies have concentrated on tasks as they are experienced in classrooms. While propositions concerning task systems are sparse in any curriculum area, language arts classes would seem to be particularl… more

Accurate Empathy and Rorschach Interpretation

Description: Although the Rorschach is one of the most widely used psychological assessment techniques, its empirical support has been equivocal. One possible explanation for this lack of empirical support is the tendency for researchers to study only the assessment tool with little regard for the clinician using it. The current study examined one clinician variable (empathy) and its relationship to accuracy of interpretation of the Rorschach. The literature regarding Rorschach theory and research and empat… more

Adherence/Compliance to Exercise Prescription: A Test of the Self-Efficacy Model

Description: It has been well-documented in the literature that there are many physical and psychological benefits to be derived from regular aerobic exercise. It has also been noted that adherence/compliance to aerobic exercise regimens tends to be quite low. Investigators have found that a number of factors tend to correlate with adherence, but it has been difficult thus far to determine a mechanism which underlies a tendency to adhere versus a tendency to drop-out. This study examined the problem of non-… more

Aerobic Conditioning: Effects on Locus of Control, Mood States, and General Well-Being

Description: This study was conducted to examine the sequelae of cardiovascular conditioning on locus of control, short-term mood, and psychological well-being. A pre-post test design, with control group, was used to measure the effects of a one month program of aerobic conditioning on adult volunteers. This study also sought to examine ways in which fitness changes covaried with psychological changes, and to describe patterns of change taking place during aerobic conditioning.

Aesthetic Justifications for Music Education: a Theoretical Examination of Their Usefulness

Description: Justifications for music education have been studied only by examining historical trends in statements of aesthetic versus utilitarian values, and not from the perspective of evaluating the justifications' usefulness. A number of prominent writers in the music education field, while supporting aesthetic values as important for music education, have expressed doubts about the effectiveness of aesthetic justifications when used for convincing outsiders of the importance of music in the public sch… more

Three hypotheses that were tested predicted that there would be a significant difference between the control group and the experimental group on adjusted mean scores on aggressive behavior on post test scores. The measuring instruments used were the Child Behavior Checklist Parent Report Form, the Child Behavior Checklist Teacher Report Form, and the Child Beh… more

Algebraic Numbers and Topologically Equivalent Measures

Description: A set-theoretical point of view to study algebraic numbers has been introduced. We extend a result of Navarro-Bermudez concerning shift invariant measures in the Cantor space which are topologically equivalent to shift invariant measures which correspond to some algebraic integers. It is known that any transcendental numbers and rational numbers in the unit interval are not binomial. We proved that there are algebraic numbers of degree greater than two so that they are binomial numbers. Algebra… more

Alternate Substrates and Isotope Effects as a Probe of the Malic Enzyme Reaction

Description: Dissociation constants for alternate dirmcleotide substrates and competitive inhibitors suggest that the dinucleotide binding site of the Ascaris suum NAD-malic enzyme is hydrophobic in the vicinity of the nicotinamide ring. Changes in the divalent metal ion activator from Mg^2+ to Mn^2+ or Cd^2+ results in a decrease in the dinucleotide affinity and an increase in the affinity for malate. Primary deuterium and 13-C isotope effects obtained with the different metal ions suggest either a change … more
