The Substance Abuse Subtle Screening Inventory: a Predictive Validity Study with Criminal Offenders Mandated to Rehabilitative Treatment
The Substance Abuse Subtle Screening Inventory was constructed to screen for substance abuse patterns despite non-admittance of respondents. Predictive validity studies of the SASSI are limited, and are not available for probationers. Participants were 147 male and 54 female probationers mandated to treatment. Overall differences among SASSI scales were significant for treatment compliance and outcome. Higher SASSI scales were found among those probationers who were compliant/successful. Individual scales were not significantly different, however, a trend was revealed; those respondents who scored higher tended to comply/succeed in treatment. The SASSI alone accurately classified 59.7% of respondents. In summary, the SASSI's use in predicting treatment outcome is limited and should be employed with concomitant data.
The Fairy Star; or Boucicault's Revenge: a Melodrama in One Act
The Fairy Star; or Boucicault's Revenge is based on an incident which occurred in the relationship between actress Agnes Kelly Robertson and her common-law spouse, the actor and dramatist Dion Boucicault. The action of the play takes place late in the afternoon of September 3, 1875, in the parlor of Robertson's home, Langham Place. The dramatic conflict revolves around their meeting for the first time after a two-year separation, during which time Boucicault had forced Robertson to virtually retire from the stage and remain at home with their six children. When Robertson learns that Boucicault desperately needs her to star in his latest theatrical production, she sets out to win back her place as the star of both his life and his plays.
Eudora Welty's "Flowers for Marjorie" : Toward the Caesura of the Unconscious
Eudora Welty's short story "Flowers for Marjorie" appears in A Curtain of Green and Other Stories, her first volume of collected stories published in 1941. Since the story's publication, literary scholars have interpreted the protagonist's murder of his wife, and the unusual events that follow, in terms of somatic realities that inform the text. This thesis is a psychoanalytic rereading/rewriting of "Flowers for Maijorie" that attempts to analyze its text as a possible dream narrative. By psychoanalytically rereading/rewriting the narrative in this story as a possible dream narrative, this thesis will attempt to demonstrate how the reader might experientially break through its previous resistance to interpretation, which should encourage a better understanding of the story's narrative ambiguities. The originality of this examination lies in its detailed analysis of the story's text from a psychoanalytic economy, thus providing perhaps the most detailed analysis of its text to date.
A Rhetorical Analysis of Major Oil Companies' Advertisements in 1990 : A Semiotic Approach
This study demonstrates how discourse is used to construct popular myths. This study analyzes magazine advertisements used by businesses in overcoming the rhetorical problem posed by a public opinion that blamed them for environmental problems. This study shows how businesses used advertisements to construct a popular myth that businesses were doing their part in overcoming the environmental crisis.
Assessment and Analysis of Per Pupil Expenditures: a Study Testing a Micro-Financial Model in Equity and Student Outcome Determination
The purpose of this study was to examine district level financial data to assess equity across districts, to compare equity benchmarks established in the literature using selected functions from the state's financial database, and to determine the predictive value of those functions to the Texas Assessment of Academic Skills (TAAS) tests of 1997.
Analysis of Phytoplankton Responses to Water Chemistry Dynamics in a Moderately Eutrophic North Texas Reservoir
Canonical correspondence analysis (CCA) was used to explore relationships between measured environmental variables and in situ phytoplankton communities in a moderately eutrophic North Texas Reservoir.
Mobiles is a composition for an ensemble consisting of 12 instruments. The piece, in one movement, incorporates intuition, chance, and twelve tone techniques and reflects the relationship between motion and rest or tension and release. The structure is modeled according to principles of growth and decay, starting off slowly, building, and then dying away. Much of the material is inspired by mental images invoked from modern theories concerning chaos. Mobiles' character stems from the principal use of two motives, the chaos motif and the echo motif. Primarily, the chaos motif is representative of a state of motion while the echo motif represents a state of rest. Mobile architecture is usually characteristic of symmetry, balance, and proportion, but because of uncertainty in a natural environment, this proportion often falls short of a perfect symmetrical balance as in the case of a crystal or a fractal design. It is this kind of architecture that Mobiles portrays in its form and developmental process.
Texas Public School Mission Statements : a Factor in the Involvement of Parents, Family, and/or Home in Educational Reform
Despite site-based decison making (SBDM) educational mandates, research determined the virtual exclusion of parents, family, and/or home as co-authoritative voice in Texas public school district mission statements. Qualitative analysis determined six parent roles within 155 inclusive mission statements through rhetorical deconstruction, a text-based grammatical evaluation procedure; quantitative analysis determined no significance between inclusive and exclusive districts in factors of size, socioeconomic status, and ethnicity. The implications of this study add further support to the growing parental insistence for greater educational decision-making options: ie., home schooling, voucher system, and charter schools.
A Political and Macroeconomic Explanation of Public Support for European Integration
This study develops a model of macroeconomic and political determinants of public support for European integration. The research is conducted on pooled cross-sectional time-series data from five European Union member states between 1978 and 1994. The method used in this analysis is a Generalized Least Squares - Autoregressive Moving Average approach. The factors hypothesized to determine a macroeconomic explanation of public support for integration are inflation, unemployment, and economic growth. The effect of the major economic reform in the 1980s, the Single European Act, is hypothesized to act as a positive permanent intervention. The other determinants of public support are the temporary interventions of European Parliament elections and the permanent intervention of the Maastricht Treaty in 1992. These are hypothesized to exert a negative effect. In a fully specified model all variables except economic growth and European Parliament elections demonstrate statistical significance at the 0.10 level or better.
Diane Di Prima: The Muffled Voice of the Beat Generation
The Beat rejection of conventional values meant a rejection of marriage, family, and a nine-to-five job, and few women were prepared to make that kind of radical shift in a society that condemned women for behaving the way the Beats behaved. Though she has faced difficulty in getting published, Beat writer Diane Di Prima has been publishing steadily for the past forty years. Di Prima has also lived the life of a Beat, wandering the country, avoiding nine-to-five work and supporting herself with grants, teaching and poetry readings. In spite of her success and adherence to the Beat lifestyle, Di Prima has given birth to five children, all of whom she took with her in her travels. Diane Di Prima has always faced the particular challenge of gaining the acceptance of her male peers amid indifference and hatred toward her sex while not allowing these men to go unanswered.
The Electronic Ranch: the Information Environment of Cattle Breeders
The present study was a longitudinal analysis of the information needs of Red Angus cattle breeders and their use of networked information services. It was based on two surveys. The first, conducted in 1995--96, polled all 1067 ranches of the Red Angus Association of America. Responses from 192 Red Angus breeders were used to determine the value of different information types and to evaluate perceptions of the greatest barriers to the adoption of network information services. The second survey, mailed to 41 Red Angus breeders in 1998, focused on early adopters and likely users of network services. Responses from 15 breeders were used to evaluate perceptions of the greatest barriers to the effective use of Web-based information services.
The Applicability of SERVPERF in Judging Service Quality for Biomedical Information Professionals
The applicability of SERVPERF as a tool for judging the quality of services used by biomedical information professionals was tested using standard statistical procedures. Data was gathered nationally via a combination of electronic and non-electronic forms, from Area Health Education Center (AHEC) information professionals and the results consolidated to provide information for the study. It was determined that SERVPERF was applicable in making judgements about service quality for AHEC information professionals. Their perceptions about service quality tended to have a greater influence than did their level of actual satisfaction on whether or not they planned to use a particular service in the future. There is currently no validated tool available to ascertain the quality of services offered to these valuable members of the rural health care team. This dissertation proposes to provide such a tool, and to serve as a guide or template for other professionals seeking a means to judge service quality in their own disciplines.

Evaluation of a Constructed Wetland to Reduce Toxicity from Diazinon at the Pecan Creek Wastewater Treatment Plant, Denton, TX
The City of Denton Pecan Creek Wastewater Treatment Facility has periodically failed effluent toxicity testing. A Toxicity Identification Evaluation has determined that Diazinon in the effluent is contributing to the observed toxicity. Chlorpyrifos is also implicated as a factor. The City of Denton constructed a half acre experimental wetland to remove Diazinon related toxicity. Results from spiking and microcosm experiments indicate that the wetland can reduce the Diazinon.
Chaucer and the Rhetorical Limits of Exemplary Literature
Though much has been made of Chaucer's saintly characters, relatively little has been made of Chaucer's approach to hagiography. While strictly speaking Chaucer produced only one true saint's life (the Second Nun's Tale), he was repeatedly intrigued and challenged by exemplary literature. The few studies of Chaucer's use of hagiography have tended to claim either his complete orthodoxy as hagiographer, or his outright parody of the genre. My study mediates the orthodoxy/parody split by viewing Chaucer as a serious, but self-conscious, hagiographer, one who experimented with the possibilities of exemplary narrative and explored the rhetorical tensions intrinsic to the genre, namely the tensions between transcendence and imminence, reverence and identification, and epideictic and deliberative discourse.
Cultural Influences on the ABC Implementation under Thailand's Environment
This study examines the influences of culture on the implementation of a U.S.-based Activity-Based Costing (ABC) in three Thai organizations.
Mobile Order Theory as Applied to Polycyclic Aromatic Heterocycles
Experimental mole fraction solubilities of benzil, thianthrene, trans-stilbene, thioxanthen-9-one, diphenyl sulfone and dibenzothiophene sulfone are determined in pure noncomplexing and complexing solvents. Predicted solubility values are calculated for benzil, thianthrene, trans-stilbene and thioxanthen-9-one using expressions derived from Mobile Order theory. Large deviations between experimental and predicted solubilities in alcohol solvents exist, therefore optimized solute - solvent association constants are determined. Previously measured thianthrene solubilities in five binary alkane + cyclohexane solvent mixtures are compared with values predicted from Mobile Order theory using the measured solubility in each of the pure solvents as input parameters. The experimental mole fraction solubility of benzil in eight binary alcohol + 1-octanol solvent mixtures are also measured and compared with predicted values.
Development and Validation of the Checklist for Differential Diagnosis of Attentional Problems
The current study discussed the development and validation of the Checklist for Differential Diagnosis of Attentional Problems (CDDAP), a tool for use with adults seeking diagnosis and treatment of an Attention Deficit Hyperactivity Disorder. Normative data are provided on three subject groups (ADHD adults, controls, and adults with other psychiatric disorders). Convergent validity was established with the SCL-90, and criterion validity established through comparing scaled scores with final diagnoses. Overall, this measure was accurate at differentiating adults with ADHD from controls and adults with other psychiatric disorders. Results indicated that the CDDAP was also able to identify other psychiatric disorders with 71 to 92% accuracy, depending on the disorder.
The Effects of a Brain-based Learning Strategy, Mind Mapping, on Achievement of Adults in a Training Environment with Considerations to Learning Styles and Brain Hemisphericity
This study examined the effectiveness of Mind Mapping (a diagram of the structure of ideas in an associative manner, using graphics, color and key words) as a note-taking device in a training course in a large, high-tech corporation, as compared to traditional note-taking. The population for this study consisted of personnel employed by a major high-tech firm, that had voluntarily registered for a Mind Mapping training class. The effect of Mind Mapping was measured by the pre-test and post-test of the control and experimental groups.
The Motivational Impact of Incentive Programs on Young Adult Employees in Corporate Casual Restaurants
This study was conducted to determine which incentive programs best influence young workers in corporate casual restaurants. The server and bar staff of the Chili's division of Brinker International, Inc. were surveyed in 18 stores in the Dallas area. From the sample. 356 usable surveys were received. The study was designed to obtain feedback about existing and future incentive programs that will enhance development of a positive working environment, along with higher productivity and a lower turnover rate.
Local or Transnational Television Programming: Media Globalization in East Asia, with an Emphasis on Development in the People's Republic of China
This study focuses on the relationship between Western transnational broadcasters and East Asian media. It analyzes 1) the processes through which Western media players are localized and 2) the impact of media globalization on local broadcasters in East Asia. Recent developments in the People's Republic of China are the primary focus in the discussion of local media.
Effects of External Electric Fields on Light Transmittance in Isolated Crayfish Nerves
Acute effects of a pulsed external electric field (PEEF) at 20 V/cm and a d.c. EEF at 90 V/cm on light transmittance in an isolated compound crayfish nerve was measured. In a third series, the nerve was pre-treated with the Na+ channel blocker tetrodotoxin (TTX). A PEEF produced an irreversible increase in the variation of light transmittance in normal nerves but a reversible increase in TTX treated nerves. This data was statistically insignificant. The d.c. EEFs produced a reversible and statistically significant enhancement of variation in light transmittance in both untreated and TTX-treated nerves. The findings may be due to either (1) an alteration in the ion/fluid flux within the nerve or (2) a physical alteration of protein molecules in the membranes.
Designing a Social Marketing Plan to Promote Hispanic Participation at Prostate Cancer Screenings
Prostate cancer is the most commonly occurring cancer and the second leading cause of cancer death for men in the United States. Because early prostate cancer is frequently without symptoms and data on how to prevent prostate cancer is lacking, early detection has the greatest potential for decreasing mortality. Studies have shown Hispanics/Latinos to be less likely than whites or African-Americans to utilize prostate cancer screening exams. The purpose of this descriptive study was to design a social marketing plan which could be used as a model to promote Hispanic/Latino participation at prostate cancer screenings. Information obtained through medical and marketing literature review, the author's experiences serving on the promotion committee of a community-sponsored prostate cancer screening project, and interviews with 51 Hispanic/Latino prostate cancer screening participants is described and incorporated into a guide with recommendations for future program planners.
A Study of the Relationships among Relational Maintenance Strategy Usage, Communicator Style and Romantic Relational Satisfaction
This thesis examined student-participants' self-reported use of romantic relational maintenance strategies and their partners' reports of relational satisfaction. Additionally, individuals outside the romantic relationship reported on student-participants' general communicator style. The research proposed that general style reports would be predictive of relational maintenance strategy usage and of romantic partners' relational satisfaction. The study found that general style behaviors may not be indicative of relational maintenance strategy usage or romantic partners' relational satisfaction. Tests of sex differences revealed that females' expression of various relational maintenance strategies and style behaviors are associated with male partners' relational satisfaction; however, no results were obtained indicating specific behaviors expressed by males result in female partners' relational satisfaction.
State-Receiver Apprehension and Uncertainty in Continuing Initial Interactions
This study examined state-receiver apprehension and uncertainty as they relate to each other and to information seeking and confirmation of relational predictions in initial interactions.
Autographs 1928 : Four Songs for Soprano and Chamber Ensemble
Autographs 1928: Four Songs for Soprano and Chamber Ensemble is a composition of approximately 16 minutes' duration and is scored for mezzo-soprano, flute, oboe, clarinet, horn in F, viola, violoncello, one keyboardist (piano and celesta), and two percussionists (marimba, xylophone, chimes, timpani, bass drum, temple blocks, triangle, and slapstick). The work consists of four songs and four readings with texts from Walls's maternal grandmother's autograph book. The composition opens with a reading and alternates between readings and songs. The music is intended to reflect the playful, tender and humorous nature of the lyrics.

A New Framework for Classification and Comparative Study of Congestion Control Schemes of ATM Networks
In our work, we have proposed a new framework for the classification and comparative study of ATM congestion control schemes. The different aspects on which we have classified the algorithms are control theoretic approach, action and congestion notification. These three aspects present of the classification present a coherent framework on which congestion control algorithms are to be classified. Such a classification will also help in developing new algorithms.
DNA Typing of HLA-B by PCR with Primer Mixes Utilizing Sequence-Specific Primers
The aim of this study was to design a resolution typing system for the HLA-B gene. This technique involves a one-step PCR reaction utilizing genomic DNA and sequence-specific primers to determine the specificity of each allele and to produce a larger primer data base ideal for serological analysis. The application of this technique to serological analysis can improve serology detection which is currently hindered by antibody cross-reactivity and the unavailability of useful typing reagents.
Depression in Sixth-Grade Early Adolescents: Effects of Intimate Support, Relationship Conflict, and Self-Efficacy
Depressive symptomology was examined in this study as a function of conflict and intimate support with parents, friends, and siblings among a non-clinical sample of 223 predominately white sixth-grade early adolescents. Moreover, sixth-graders' depressive symptomology was examined as a function of conflict management self-efficacy and intimate support self-efficacy. The purpose of the present study was twofold: 1) to explore the effects of intimate support and conflict in family and friend relationships on sixth-grade early adolescent depressive symptomology, 2) to determine whether poor conflict management skills self-efficacy and poor intimate support self-efficacy are linked with depressive symptomology in sixth-grade early adolescents. Friend relationship qualities had little impact on depression in sixth-graders. However, the presence of conflict and deficits in family intimate support, especially from parents, was associated with increased depression. Increased levels of depression also corresponded with lower ratings of conflict management self-efficacy and intimate support self-efficacy. Moreover, relationship difficulties combined with self-efficacy deficits to affect depression.
Post Time
Post Time is a non-fiction video program depicting some of the careers found at North American horse race tracks. Through the use of videotaped footage taken at eight race tracks and three training farms, the horse racing industry's trainers, jockeys, owners and grooms are profiled in the world they call the backstretch. The video begins with a brief history of horse racing and the origins of thoroughbred horses followed by closer examinations of the economic and social experiences faced by the owners, trainers, jockeys, and grooms as they attempt to prepare horses for racing every week.
Nucleotide Sequence of a Bovine Arginine Transfer RNA Gene
A single plaque-pure lambda clone designated λBA84 that hybridized to a ˆ32P-labeled bovine arginine tRNA was isolated from a bovine genomic library harbored in a lambda bacteriophage vector. A 2.3-kilobase segment of this clone was found to contain an arginine transfer RNAccg gene by Southern blot hybridization analysis and dideoxyribonucleotide DNA sequencing. This gene contains the characteristic RNA polymerase III split promoter sequence found in all eukaryotic tRNAs and a potential RNA polymerase III termination site, consisting of four consecutive thymine residues, in the 3'-flanking region. Several possible cis-acting promoter elements were found within the 5'-flanking region of the sequenced gene. The function of these elements, if any, is unknown.
Academic Achievement: Examining the Impact of Community Type at a Small Liberal Arts College in Texas
Hierarchical regression was used to determine if high school community type is an effective predictor of academic success when controlling for demographics, prior academic achievement, socioeconomic status, and current commitment or work habits for students entering Austin College in 1992,1993, and 1994 . Findings revealed that there is a relationship between attending high school in community types of rural and independent town controlling for the effects of SAT scores, high school rank, sex, and late application deposit on first semester grade point average.
The Perception of Western Wear Status Symbols Among Western Wear Consumers
This study determined whether an association exists between the perception of western wear status symbols and demographic characteristics {i.e., gender, age, income, and education level) among Texas American Paint Horse Association members.
The Role of Gabergic Inhibition in Modulating Receptive Field Size of Cuneate Neurons
A blockade of GABAergic inhibition increases the receptive field(RF) size of most somatosensory cortex (SI) and some ventrobasal thalamus (VB) neurons. The results suggest RF size of cuneate neurons may be modulated through GABAa and GABAb receptors, independent of firing frequency.
Subcloning and Nucleotide Sequence of the xylO/PUWCMA Region from the Pseudomonas putida TOL Plasmid pDK1
The TOL plasmids of Pseudomonas putida encode enzymes required for the oxidation of toluene and other related aromatic compounds. These genes are organized into two operons, the xylUWCMABN operon (upper), and the xylXYZLTEGFJQKIH operon (lower). Here we report the nucleotide sequence of a 7107 bp segment of the TOL pDK1 plasmid encoding the region just upstream of the "upper" operon through the genes encoding xylUWCMA. Sequence analysis, comparison of base-usage patterns, codon-usage patterns, and intergenic distances between genes help support the idea that the "upper" and "lower" operons have evolved independently in different genetic backgrounds and have only more recently been brought together in TOL and related catabolic plasmids.
Effects of Performance Levels of Subject Matter Experts on Job Analysis Outcomes
Much research has been undertaken to determine how Subject Matter Expert characteristics affect job analysis outcomes. The current study seeks to discover if performance levels are related to current incumbents ratings of their positions. A group of 114 corporate associates, from two administrative positions, served as Subject Matter Experts (SME) for this study. Separate job analyses for each position were conducted using the Job Analysis Task Checklist. The results for each job were analyzed to determine if SME performance levels affected job analysis outcomes. The results for both jobs showed that there were very few differences in job analysis results as a function of SME performance levels.
Applications of Reductive Analytical Techniques in the Phrygian Settings of the Orgelbüchlein by J.S. Bach
This study aims to two problematic aspects of the Phrygian mode: a. the development of a harmonic pattern at the cadence that differs from that of the other modes and of the major and minor modes as well; b. the observation that the Phrygian scale inverts all of the intervallic properties of the Major scale. The result of these two observations is that when the reductive techniques of Heinrich Schenker are applied in the Phrygian repertory, melodic and harmonic properties are brought into conflict with each other. However, application of alternative models of the Ursatz developed by Lori Burns has certain benefits for demonstrating musical properties in the Phrygian repertory.
The History of the 389th Bombardment Group (H): a Study of the Use and Misuse of Strategic Bombers in the Second World War
This thesis describes and evaluates the successes and failures of the use of strategic bombers through the abilities of one heavy bombardment group, the 389th. It examines the different missions that determined the effectiveness of the Group. When employed in a strategic bombing role, the 389th contributed significantly to the destruction of the German war industries and transportation system. When used as a tactical bomber, a mission for which it had neither proper training nor equipment, the 389th was generally a failure.
Distorted Time Perception as an Underlying Factor of Psychosis Proneness and Dissociation
Distortions in the perception of time historically have been associated with dissociation and psychosis in clinical populations. However, the relations among dissociation, psychosis, and time perception in sub-clinical populations have not been investigated. In the present study, college undergraduates scoring either normally or deviantly high on the Per-Mag were given a Dissociative Experiences Scale (DES) and a computerized time-estimation/production task. Participants scoring high on the Per-Mag obtained higher scores on the DES than participants scoring low on the Per- Mag. Per-Mag scores also correlated positively with DES scores across 608 total participants screened. The relation between dissociative and psychotic symptomatology is discussed considering dichotomous versus continuous conceptualizations of psychopathology. The effects of intelligence, social desirability, malingering, gender, and post-traumatic stress on the measures used are also discussed.
Personality Correlates of Anorexia Nervosa in a Nonclinical Sample
The purpose of this study was to examine the relationship between anorexia nervosa and several personality traits. Past research in this area has been contradictory for several reasons. Sociocultural theories have described the media's role in promoting eating disorders by portraying a thin body-type as the ideal. However, they have neglected to describe the personality ideal which our society promotes in women. It is proposed here that anorexics incorporate and oppose this ideal. Therefore, the anorexic personality is one filled with conflict.
An Evaluation of the University of North Texas' "Youth Opportunities Unlimited" Program (a Compensatory Education Program for At-Risk, Secondary School Students)
Even though the Youth Opportunities Unlimited program has been in effect for ten years, there exists no current, comprehensive, effectiveness research on YOU. Such analysis is needed to determine the value of the YOU program. The purpose of this study is to evaluate the effectiveness of the YOU program. Both quantitative and qualitative research methods are used in this study. Quantitative analysis is provided through factual data collected through an alumni survey. Qualitative analysis is provided through personal opinion information obtained from YOU alumni through the survey and by personal interview. The YOU program at UNT is a successful compensatory education program that helps improve the education and the lives of America's at-risk students.
The Role of a Point Loss Contingency on the Emergence of Derived Relations in the Absence of Original Relations
The role of point loss for symmetrical relations introduced simultaneously with probe trials in the absence of original relations on all probe trial performances was evaluated. Training was completed after six conditional discriminations were established in two contexts. Point loss was introduced simultaneously with probe trials in the absence of original relations in the first context. Probe trials with no point loss in the absence of original relations were introduced in the second context. The simultaneous introduction of probe trials and the point loss contingency may in some cases prevent the emergence of an equivalence class in the context that contained the point loss as well as in the context where no point loss occurred.
Simulating Thermal and Chemical Spills in Coupled Cooling Reservoirs
Hot water discharges and potential chemical spills are factors that threaten water quality in cooling reservoirs of chemical and power plants. In this thesis, three models are used to analyze the impact of these factors in a particular case study.
Evaluation of the Use of the Bivalves Ischadium recurvum Rafinesque, 1820 and Corbicula fluminea Muller, 1774 as Biological Indicators of Relative Water Quality in Terms of Growth and Upper Temperature Tolerance
Growth of mussels under laboratory conditions was examined under various food regimes in different water types and temperatures. Growth was less than would be useful as an indicator and comparisons with field exposures were of minimal value. The effects of organophosphates on bivalves were examined via toxicity tests, tissue concentration, and by controlling exposure through the use of physical constraints. Upper temperature tolerance of both bivalve species was examined with respect to different acclimation temperatures and organophosphate exposures. Deviations from control exposures occurred at some temperatures. Copper effectively lowered the mean heat coma temperatures of C. fluminea at some concentrations, however, chlorine exposures did not alter heat coma temperature.
Heat Shock Proteins in Ascaris suum
Ascaris suum were exposed to a number of stressors, including heavy metals and both high (40°C) and low (18°C) temperatures. The 70kD and 90kD heat shock proteins (HSPs) in the different A. suum tissues were analyzed by Western blot and quantitated by Macintosh Image Program.
Disturbing the Peace
Disturbing the Peace is a short, 16mm sync-sound fiction film. Alone one stormy night, a woman must contend with an intruder breaking into her home. The intruder turns out to be a teenage boy. He claims to have broken in only to retrieve a family heirloom he hid there when he and his parents lived in the same house years ago. When the boy finds the heirloom, the woman begins to believe his story, and soon realizes he doesn't have a good home life. The boy asks permission to stay until the storm breaks. She agrees. Should the boy be trusted, or is he telling one lie after another? The police arrive to witness the outcome of the story.
Cluster Analysis of the MMPI-2 in a Chronic Low-Back Pain Population
The Minnesota Multiphasic Personality Inventory (MMPI) is the most frequently used psychological measure in the assessment of chronic pain. Since the introduction of the MMPI-2 in 1989 only two published studies have focused on cluster analysis of chronic pain patients. This study investigated MMPI-2 cluster solutions of chronic low-back pain patients. Data was collected from 2,051 chronic low-back pain patients from a multidisciplinary pain clinic in the southwestern United States. A hierarchical clustering procedure was performed on K-corrected T-scores of the MMPI-2 using the three validity and ten clinical scales. Four relatively homogeneous subgroups were identified for each sex with the MMPI-2. In general, these results replicated the findings of previous researchers using both the MMPI and MMPI-2.
