A Comparison of PPVT and PPVT-R Scores of Mentally Retarded Adults (open access)

A Comparison of PPVT and PPVT-R Scores of Mentally Retarded Adults

The comparability of PPVT and PPVT-R scores among retarded adults were examined. The sample consisted of 96 clients, who had been previously diagnosed as mildly, moderately, or severely retarded. The PPVT (Form A) and PPVT-R (Form L) were administered to all participants in counter balanced order. Significant correlations were found between the two tests for the total sample as well as for females and males. Additionally, the PPVT-R was found to be capable of discriminating differing levels or retardation. However, with the exception of the severely retarded group, mean PPVT-R Standard Score Equivalent (SSE) scores tended to be approximately 20 points lower than PPVT IQ scores. Some clinical implications of these results were discussed.

The Enlightenment and the Englishwoman (open access)

The Enlightenment and the Englishwoman

The present study investigates the failure of the Enlightenment to liberate Englishwomen from the prejudices society and law imposed upon them. Classifying social classes by lifestyle, the roles of noble, middleclass, and criminal women, as well as the attitudes of contemporary writers of both sexes, are analyzed. This investigation concludes that social mores limited noblewomen to ornamental roles and condemned them to exist in luxurious boredom; forced middle-class women to emulate shining domestic images which contrasted sharply with the reality of their lives; subjected women of desperate circumstances to a criminal code rendered erratic and inconsistent by contemporary attitudes, and impelled the Enlightenment to invent new defenses for old attitudes toward women.

An Investigation of Personality Characteristics of Bulimic Women Late Adolescent Through Adult Ages in the Dallas/Fort Worth Metroplex (open access)

An Investigation of Personality Characteristics of Bulimic Women Late Adolescent Through Adult Ages in the Dallas/Fort Worth Metroplex

The incidence of bulimia seems to be increasing dramatically as actors, models, dancers, and college populations are seeking help for this eating disorder. In this study, the Adjective Checklist was administered to 21 bulimic women and 17 normal women to compare personality characteristics on the following scales: abasement, affiliation, autonomy, achievement, aggression, personal adjustment, succorance, and self-control. Results showed bulimic women scored higher on abasement and succorance. A multiple regression was performed which elucidated the scales responsible for the greatest amount of variance. These were aggression, autonomy, and self-control. Further studies of personality measures may aid in describing this population more fully.

Texas Outlaw Radio: the Prelude to United States v. Gregg et al. (1934) (open access)

Texas Outlaw Radio: the Prelude to United States v. Gregg et al. (1934)

Unlicensed radio stations in 1933 tested the Radio Act of 1927 as to whether or not the Federal Radio Commission (FRC) had the right to regulate radio stations whose signals were allegedly intrastate. The FRC believed it could regulate such radio stations and proceeded to confiscate equipment, charge individuals with violation of the law, and bring them to trial, either in an injunction hearing, a criminal trial, or both. The most formidable case was that of United States v. Gregg et al. The challenge was met by the FRC and the judge, whose decision is still quoted in legal documents. The decision upheld the Radio Act of 1927 and the FRC's right to regulate all radio stations, licensed or unlicensed.

Role of Calcium and Phospholipids in Transepithelial Sodium Ion and Water Transport in Amphibian Epithelia (open access)

Role of Calcium and Phospholipids in Transepithelial Sodium Ion and Water Transport in Amphibian Epithelia

The present investigation is concerned with determining the role of calcium, phospholipids, and phospholipid metabolites on transepithelial sodium and water transport in response to antidiuretic hormone (ADH). These studies utilize the frog skin for determining sodium transport and amphibian urinary bladder for water flow measurements and scanning electron microscopy of cell surface morphology. The results demonstrate that phospholipids and phospholipid metabolites containing arachidonic acid stimulate transepithelial sodium transport through amiloride sensitive channels and the action of these lipids involves the synthesis of prostaglandins. These lipids also inhibited the increase in water flow induced by ADH, and this effect was prevented with prostaglandin synthesis inhibitors. Prostaglandins alter intracellular calcium concentrations and agents effecting calcium metabolism alter cell surface morphology and the changes in surface substructure induced by ADH. These observations support the hypothesis that alterations in membrane permeability to water and ions may involve metabolism of membrane phospholipids and prostaglandin biosynthesis.

Determination of Halogens in Organic Compounds by Using Sodium Fusion-Ion Chromatography Method (open access)

Determination of Halogens in Organic Compounds by Using Sodium Fusion-Ion Chromatography Method

A sodium fusion-Ion chromatographic method for determination of fluorine, chlorine, bromine, and iodine in organic compounds is described. Seventeen organic halogen compounds and eleven mixtures were decomposed by Na fumes at 280-290°C for one hour or longer. The absorbing solutions were injected for ion chromatographic analysis using electrochemical and conductometric detectors. The arrangement of the apparatus includes the placement of the electrochemical and conductometric detectors. This method provides a mechanism providing for complete analysis for all four halogens in one ion chromatographic sample injection. Reproducibility is excellent and liquid sample handling is mentioned.

Stephen Dedalus and the Beast Motif in Joyce's Ulysses (open access)

Stephen Dedalus and the Beast Motif in Joyce's Ulysses

This study is an examination of the beast motif associated with Stephen Dedalus in Joyce's Ulysses. The motif has its origins in Joyce's earlier novel, A Portrait of the Artist as a Young Man. In Ulysses the beast motif is related to Stephen's feelings of guilt and remorse over his mother's death and includes characterizations of Stephen as a fox, a dog, a rat, and a vampire. The motif consistently carries a negative connotation. Several literary sources for the imagery of the beast motif are apparent in Ulysses, including two plays by John Webster, a poem by Matthew Prior, medieval bestiaries, and a traditional Irish folk riddle. The study of the continuity of the beast motif in Ulysses helps to explain the complex characterization of Stephen Dedalus.

A Study of the Effectiveness of Four Competing Scenarios in Explaining the Causes of Stagflation (open access)

A Study of the Effectiveness of Four Competing Scenarios in Explaining the Causes of Stagflation

This study investigates the relationship between stagflation and price stability and full employment and four economic scenarios and the economic condition. The data used in the study were obtained from government publications and were analyzed using hierarchical multiple regression. The standard inferential apparatus were employed. Give independent variables were found to be significant in explaining the causes of stagflation. These were: absolute change in M1, oil embargo of 1974, corporate profits, output per hour, and Iranian crisis of 1979. In conclusion, the causes of economic instability do not rest with one single theory or factor, but a combination of several.

Impact of the 1965 Immigration Act on Countries of Origin and Occupational Groups of the International Migrants to the United States (open access)

Impact of the 1965 Immigration Act on Countries of Origin and Occupational Groups of the International Migrants to the United States

The purpose of this research is to investigate the changes in countries of origin and occupational groups of immigrants to the United States after the implementation of the 1965 Immigration Act. The basic policy change in the 1965 Immigration Act was essentially the abolition of the National Origins Quota System. The new law led to obvious changes in the origins of immigrants. The number of Southern European, Asian and Caribbean immigrants significantly increased since the implementation of the Act. The sources of the various occupational groups shifted to some extent. The number of immigrants in the professional and highly skilled categories increased significantly. The impact of the changes aggravated the "brain drain" problem.

Lebanese Internal Divisions and Palestinian Guerrilla Activity, 1967-1976 (open access)

Lebanese Internal Divisions and Palestinian Guerrilla Activity, 1967-1976

This study presents the thesis that religious cleavages in Lebanon have been the major factor behind most of the country's problems since the achievement of independence in 1943. The coming of the Palestinians in 1948 and in the 1970s upset Lebanon's delicate sociopolitical balance between Christians and Muslims in favor of the latter. The study's four chapters describe the origins of Lebanon's religious groups, the arrival of the Palestinians, Lebanon's emergence as the sole Palestinian guerrilla base, and the outbreak and aftermath of the Lebanese civil war of 1975-1976. Finally, suggestions are made for the resolution of the continuing Christian-Muslim conflict, notably the alternatives of federalism and confederalism as possible future political arrangements for Lebanon.

Nutritional Requirements of Corynebacterium poinsettiae (open access)

Nutritional Requirements of Corynebacterium poinsettiae

In a minimal medium supplemented with glucose and yeast extract, the optimum pH for the growth of C. poinsettias was found to be 7.5. The organism requires thiamine, biotin, and pantothenic acid for growth. No absolute requirement was found for any amino acid, purine or pyrimidine although an amino acid mixture was stimulatory. Casamino acids could be substituted for the synthetic amino acid mixture. Yeast extract provided an additional factor(s) necessary for maximal growth. The results suggest that the unknown factor found in yeast extract might be purified by a combination of solvent extraction, and adsorption and elution from charcoal.

An Analysis of the Overt Teaching of the Monitor to Students of English as a Second Language (open access)

An Analysis of the Overt Teaching of the Monitor to Students of English as a Second Language

The overt teaching of the Monitor, or conscious rule awareness, to native Spanish-speaking ESL students was examined to note possible benefits to the students' oral English production. Native Spanish-speaking students of English (the experimental group) were taught an awareness of their ability to self-correct their spoken English. They were then compared to another group of native Spanish-speaking ESL students (the control group) in four areas: Ilyin Oral Interview score, total words produced, errors produced, and interference errors produced. The results of the study lend support to the theory that overt Monitor teaching could be beneficial to native Spanish-speaking students of English. The experimental group showed a significant gain in Ilyin scores and a significant reduction in the number of errors produced.

The Slave Trade Question in Anglo-French Diplomacy, 1830-1845 (open access)

The Slave Trade Question in Anglo-French Diplomacy, 1830-1845

This thesis concludes that (1) Immediately following the July Revolution, the Paris government refused to concede the right of search to British commanders. (2) Due to France's isolation in 1831-1833, she sought British support by negotiating the conventions of 1831 and 1833. (3) In response to Palmerston's insistence and to preserve France's influence Sdbastiani signed the protocol of a five-power accord to suppress the slave trade. Guizot accepted the Quintuple Treaty to facilitate an Anglo-French rapprochement. (4) Opposition encouraged by the Webster-Ashburton Treaty, however, forced Guizot to repudiate this new agreement. (5) As a concession to Guizot,Aberdeen dropped the demand for a mutual right of search and negotiated the Convention of 1845, establishing a system of joint-cruising.

Types of Love in Selected Plays by Lillian Hellman (open access)

Types of Love in Selected Plays by Lillian Hellman

This study analyzed The Children's Hour, The Little Foxes, Watch on the Rhine, Toys in the Attic in terms of the forms of human love delineated by Erich Fromm in The Art of Loving. The motives and actions of one or more principal characters and their dramatic situations were studied. It was discovered that, in the plays that were examined, each character responded to his or her situation in a loving or a hateful manner and that these choices with regard to love provided the dramatic matrix of the play.

A Technique for Increasing the Optical Strength of Single-Crystal NaCl and KCl Through Temperature Cycling (open access)

A Technique for Increasing the Optical Strength of Single-Crystal NaCl and KCl Through Temperature Cycling

This thesis relates a technique for increasing the optical strength of NaCl and KCl single-crystal samples. The 1.06-μm pulsed laser damage thresholds were increased by factors as large as 4.6 for a bulk NaCl single-crystal sample. The bulk laser damage breakdown threshold (LDBT) of the crystal was measured prior to and after heat treatment at 800*C using a Nd:YAG laser operating at 1.06 μm. Bulk and surface LDBTs were also studied on samples annealed at 400° C. These samples showed differences in damage morphology on both cleaved and polished surfaces, and the cleaved surfaces had improved damage thresholds. However, neither the polished surfaces nor the bulk showed improved threshold at the lower annealing temperature.

Cue-Controlled Relaxation: Saving Time Versus Efficacy (open access)

Cue-Controlled Relaxation: Saving Time Versus Efficacy

Cue-controlled relaxation is looked at to determine whether a component is efficacious as the entire procedure. Subjects were 40 male and 40 female undergraduates. Subjects were randomly assigned to one of four conditions: cue-controlled relaxation, progressive muscle relaxation, breathing exercises with a paired. cue word, on a presentation of the cue word without being paired. It was hypothesized that cue-controlled relaxation would be superior to a component of cue-controlled relaxation. It was determined that cue-controlled relaxation is not more efficacious than a particular component. Data suggests the majority of anxiety reduction takes place when the treatment focuses on the same modality from which the subject receives the most information about their anxiety. Implications and suggestions for further research are presented.

Reactivity of Five-Coordinate Intermediates Derived from (Chelate) Tetracarbonylmetal (0) Complexes (open access)

Reactivity of Five-Coordinate Intermediates Derived from (Chelate) Tetracarbonylmetal (0) Complexes

The reactivity of the [(Phen)Cr(CO)_3] intermediate with phosphines and phosphites (L) has been investigated through ligand-competition studies. This intermediate possesses virtually no ability to discriminate among L. The agreement between reactivity data for the thermal and photochemically-generated intermediates indicates that the same intermediate is produced via each process. Pulsed laser flash photolysis of (n^2-NP)M(CO)_4 (I) (M = Cr, Mo; NP = 1-diethylamino-2-diphenylphosphinoethane) in the absence and presence of P (OPr-i)_3 (L) in 1,2-dichloroethane and chlorobenzene induces unimolecular ring-opening to afford [(n^1-NP)M(CO)_4] (II), in which the bidentate ligand is coordinated through P. Reaction of this intermediate takes place through competitive ring-reclosure and attack at (II) by L to afford (I) and cis-(n^1-NP) (L)M(CO)_4.

Appearance or Function: Factors Related to the Likeability of Handicapped Individuals (open access)

Appearance or Function: Factors Related to the Likeability of Handicapped Individuals

Descriptions of obesity, cerebral palsy, and scoliosis were rank-ordered (from one to twenty) and rated on a five-point scale by 75 college students. The descriptions were of two types: with the appearance of an individual on five levels of severity of a disorder and with the appearance and level of functioning of an individual on five levels of severity of a disorder. The ranking data indicated males rank-ordered descriptions of obese individuals different from cerebral palsy (p < 0.01) and scoliosis (p < 0.05) . The ratings of the descriptions were analyzed in two studies with 2 x 2 x 2 x 5 ANOVA's. Three-way interactions of the level of severity, complexity of description, and type of disorder rated were discussed in terms of likeability of handicapped individuals .

Effects of Managerial Experience on Assertiveness, Anxiety, and Locus of Control (open access)

Effects of Managerial Experience on Assertiveness, Anxiety, and Locus of Control

The purpose of this study was to examine the effects of managerial experience on the relationships between assertiveness, trait anxiety, and internality, and on each of these constructs individually. Hypotheses were as follows: a) managers would be more assertive, internal, and less trait anxious than business students; b) males would be more assertive than females when students, not managers; and c) assertiveness and internality would relate positively to each other and negatively to trait anxiety. Subjects consisted of 30 managers and 53 business students. The first and third hypotheses were confirmed, although the assertiveness differences were not significant. Reasons for the observed outcome are discussed as well as implications for these constructs' ability to predict management potential.

Plasma Ion Concentrations in Selected Fishes from Four North Central Texas Reservoirs with Different Salinities (open access)

Plasma Ion Concentrations in Selected Fishes from Four North Central Texas Reservoirs with Different Salinities

Mean salinity concentrations in the four reservoirs (Moss, Ray Hubbard, Texoma and Possum Kingdom) ranged from 0.2 ppt in Moss Lake to 2.01 ppt in Possum Kingdom Lake. Reservoir sodium and chloride concentrations were hypotonic to hypertonic to plasma levels in all species. Interspecific differences were seen in ionic concentrations within each reservoir. Total osmotic and sodium concentrations in carp, Cyprinus carpio, were correlated to their concentrations in the reservoirs. No such relationship was noted for chloride, potassium and calcium. A laboratory study indicated that fish collection by electroshock did not bias plasma ion concentrations. Exposures to wide variations in ionic concentrations did not appear to induce stress in the species studied.

The Acute Effects of Intermittent Running on Serum CK and LDH Enzyme Activities in Runners and Non-Runners (open access)

The Acute Effects of Intermittent Running on Serum CK and LDH Enzyme Activities in Runners and Non-Runners

Acute effects of repeated sprinting upon serum creatine kinase (CK), lactic dehydrogenase (LDH), and isozymal activities were studied in five collegiate runners (R_s) and six non-runners (NR_s ). After an intermittent running treadmill test, blood sampling showed three-fold mean increases in CK with no change in LDH in both groups; group differences were insignificant (p>.05). Results suggest (1) intense anaerobic exercise produces moderate enzyme elevations; (2) relatively equivalent exercise intensities are critical to enzyme responses in exercising individuals of varying fitness levels; and (3) exercise-induced enzyme release may be consequential to muscle cell membrane permeability changes from decreased intracellular high-energy phosphates.

Properties of Normal Rat Kidney Cells Transformed by a Temperature-Sensitive Mutant (LA31) of Rous Sarcoma Virus (open access)

Properties of Normal Rat Kidney Cells Transformed by a Temperature-Sensitive Mutant (LA31) of Rous Sarcoma Virus

The basis of this investigation is to characterize growth property differences in normal versus virally transformed cells. Using a temperature-sensitive mutant of Rous sarcoma virus, the cells' transformation state is regulated by the growth temperature; at 33°C the cells are transformed, while at 39°C the cells have normal characteristics. The morphology of NRK cells is elongated and fibroblastic; when transformed the cells are rounded. Normal cells grow to a monolayer and stop, while transformed cells grow to saturation densities greater than just a monolayer amount. Transformed cells can form foci when grown in mixture with normal cells. Normal cells must be in contact with the culture vessel in order to grow, but transformed cells lack anchorage dependence for growth.

A Study of the Effectiveness of Four Competing Scenarios in Explaining Economic Instability

This study tests the relationship between certain economic scenarios and the state of the economy in regard to inflation and recession. Using data gathered from government publications, the economy was divided into periods of inflation, recession, and recession recovery. These periods were regressed against variables representing four schools of economic thought: monetarist scenario, structural scenario, power scenario, and micro, or supply side scenario. This study concludes that because of the complex nature of the economy, all representative variables have both positive and negative effects on the economy and no one scenario holds the key to economic stability.

Algorithms of Schensted and Hillman-Grassl and Operations on Standard Bitableaux (open access)

Algorithms of Schensted and Hillman-Grassl and Operations on Standard Bitableaux

In this thesis, we describe Schensted's algorithm for finding the length of a longest increasing subsequence of a finite sequence. Schensted's algorithm also constructs a bijection between permutations of the first N natural numbers and standard bitableaux of size N. We also describe the Hillman-Grassl algorithm which constructs a bijection between reverse plane partitions and the solutions in natural numbers of a linear equation involving hook lengths. Pascal programs and sample output for both algorithms appear in the appendix. In addition, we describe the operations on standard bitableaux corresponding to the operations of inverting and reversing permutations. Finally, we show that these operations generate the dihedral group D_4
