On Objects and Affections: Contemporary Representations of the Gay Man/Straight Woman Dyad in Popular Film and Television

Description: This project explores the representational strategies used to depict a gay male/straight female dyad across a variety of popular media. The study problematizes and critically evaluates how the narrativization of the dyad both challenges and reinforces stereotypes of gay men and at the same time circulates a troubling image of femininity in the figure of the straight woman. This line of argument is extended to the context of "Lifestyle Television" to demonstrate how the dyad implicitly structures two particular programs. It is suggested that the prevalence of the dyad is in part indicative of an assimilation of a particular gay identity into mainstream culture. The ideological implications of the dyad are discussed throughout this thesis.

The Effects of Electrochemical Therapy on Colon-25 Tumors in Balb-C Mice

Description: The purpose of the research was to treat immunodeficient mice, implanted with colon-25 tumors, with continuous and interrupted electrochemical therapy (ECT). ECT involves the placement of two electrodes, an anode near the center of the tumor and a cathode into the tumor periphery. A constant voltage is applied across the electrodes for a given period of time. The data showed that the interrupted and continuous ECT resulted in a decrease in mean tumor growth as compared to that of the sham controls. The histology of both ECT groups showed an increase presence of large vacuoles, randomly distributed tumor cells as well as the presence of "crevicing" in the medullary tissue. The differential leukocyte counts showed a distinct neutrophilia and lymphopenia in all groups at day 20 post tumor implantation. The results from the experimental groups appeared to support the findings of previous investigators.

The Effects of the Density of Reinforcement on the Maladaptive Behaviors of a Child With Autism

Description: The present study consists of two experiments that analyze the effects of high and low densities of reinforcemnt on the maladaptive behaviors of a 9 year old girl with autism. The first experiment investigates the isolated effects of density of reinforcement on the frequency of maladaptive behaviors during a motor imitation teaching task. High densities of reinforcement produced fewer occurrences of maladaptive behavior than low densities of reinforcement. Experiment 2 analyzes the effects of density of reinforcement during the same teaching tasks as in experiment 1 on maladaptive behavior, task accuracy, prompt resistance, and language. Maladaptive behavior did not recur during experiment 2. High density of reinforcement conditions during the second experiment showed a positive effect on the accuracy of responding and compliance with prompts.

The Impact of Conservative Protestantism upon The Time Fathers Spend with Their Children

Description: This research was concerned with the possible effects that religion, especially conservative Protestantism, has upon the performance of fatherhood. The influence of religion was assessed using the religious beliefs reported by fathers. The performance of fatherhood focused on the amount of time fathers spent meeting the physical needs of their young children. This research hypothesized that conservative Protestant fathers would spend more time meeting their children's physical needs than other Protestant fathers. Also hypothesized was that the level of conservative Protestant beliefs held by fathers is positively related to the proportion of time they spent meeting the physical needs of their children out of the total time spent by fathers and mothers combined. Finally, it was hypothesized that the level of conservative Protestant beliefs held by fathers was positively related to their membership in conservative religious denominations. In order to test whether conservative Protestantism has an effect upon the amount of time that fathers spend meeting the physical needs of their young children, this study will used data from the first wave of the National Survey of Families and Households (NSFH), completed in 1988. Regression analysis was used to test the first two hypotheses and crosstabulation analysis was used to test the third hypothesis. The first two hypotheses were not supported. However, interaction was detected between the variables of race and conservative Protestantism. Specifically, Black conservative Protestant fathers consistently did more childcare than Black non-conservative Protestant fathers, and all other Protestant fathers, whether conservative or not. The third hypothesis was accepted because an index of conservative beliefs was established using denominational labels. Like other recent studies, there was a lack of consensus about which variables predict how much time fathers will spend with their children. This study also points out the need for further research concerned with conservative Protestants and …

Faculty Use of the World Wide Web: Modeling Information Seeking Behavior in a Digital Environment

Description: There has been a long history of studying library users and their information seeking behaviors and activities. Researchers developed models to better understand these information seeking behaviors and activities of users. Most of these models were developed before the onset of the Internet. This research project studied faculty members' use of and their information seeking behaviors and activities on the Internet at Angelo State University, a Master's I institution. Using both a quantitative and qualitative methodology, differences were found between tenured and tenure-track faculty members on the perceived value of the Internet to meet their research and classroom information needs. Similar differences were also found among faculty members in the broad discipline areas of the humanities, social sciences, and sciences. Tenure-track faculty members reported a higher average Internet use per week than tenured faculty members. Based on in-depth, semi-structured interviews with seven tenured and seven tenure-track faculty members, an Internet Information Seeking Activities Model was developed to describe the information seeking activities on the Internet by faculty members at Angelo State University. The model consisted of four basic stages of activities: "Gathering," "Validating," "Linking" with a sub-stage of "Re-validating," and "Monitoring." There were two parallel stages included in the model. These parallel stages were "Communicating" and "Mentoring." The Internet Information Seeking Activities Model was compared to the behavioral model of information seeking by faculty members developed by Ellis. The Internet Model placed a greater emphasis on validating information retrieved from the Internet. Otherwise there were no other substantive changes to Ellis' model.

Teachers' Use of Children's Literature, Mathematics Manipulatives, and Scaffolding to Improve Preschool Mathematics Achievement: Does It Work?

Description: The primary purpose of this study was to determine if the implementation of an intervention involving teachers' use of children's literature, related storybook manipulatives, and a scaffolding (LMS) approach to learning would improve preschool children's mathematics test scores. Additionally, the LMS approach was examined to determine whether teachers' perceptions of their effectiveness in mathematics instruction changed from the beginning to the end of the study. The subjects of the study included 60 preschool-aged children and six teachers from two child care centers. The preschool teachers participated in either a control or experimental condition (the LMS approach) in their daily mathematics instruction with their preschool children. The researcher tested the children using the Test of Early Mathematics Ability and an abbreviated version of the Stanford-Binet Intelligence Scale. The study was based on two main research questions. The first question asked if there was a difference in the Test of Early Mathematics Ability total posttest scores between children in the literature-manipulatives-scaffolding intervention group and children in the control group after assuring equivalency of the two groups. The second question addressed if preschool teachers believed they were more effective in their mathematics instruction after implementing the LMS approach with young children. The answer to the first research question was that there was no statistically significant difference in the Test of Early Mathematics Ability total posttest scores between children in the literature-manipulatives-scaffolding group and children in the control group. However, the answer to the second question was that preschool teachers believed they were more effective in their mathematics instruction after implementing the LMS approach with young children. Recommendations for future research on early childhood mathematics include the investigation of preschool children's ability, achievement, and interest in mathematics; teachers' use of mathematics scaffolding techniques; and longitudinal mathematics interventions beginning during the preschool years.

Thresholds in avian communities at multiple scales: Relationships between birds, forests, habitats, and landscapes in the Ray Roberts greenbelt, Denton

Description: Environmental management agencies make efforts to reduce pollution loading in streams and rivers by promoting vegetated buffer zones between human activity and water. Most of these efforts do not mesh water quality-based buffer zone width requirements with conservation and wildlife values, specifically, the use of these riparian forest corridors for wildlife dispersal between habitats in highly fragmented landscapes. Forest interior birds are of the most concern to management in riparian forests due to their population declines across much of their breeding range. This dissertation investigates the role that landscape-level and habitat-level factors play on the presence of breeding birds in riparian forests, particularly the landscape and habitat factors that are influenced by human-caused fragmentation. This study describes research at the Ray Roberts Greenbelt, Denton, Texas, that explores the relationships between the landscape and forest habitats of the Greenbelt with its breeding bird community. The major findings of this study are that bird communities in the corridor forests are associated with a greater array of factors than are bird communities in patches, suggesting that the birds of patch forests are somewhat insulated from landscape-scale effects. Also, habitat values can be maintained in corridors, but there does not seem to be a significant relationship between the bird communities and the habitat. Forest factors are the primary influences (as inferred from the number of associations and the relative strength of these associations) on the bird communities of the Ray Roberts Greenbelt. Thresholds of richness or abundance in the amount of forest as compared with the forest interior bird community suggest that patches are better than corridors to support this community, and that the more interior forest available, the better for forest interior birds. The suggested minimum amount of forest derived from these thresholds is 35% of the amount of forest within 1 kilometer …

Feigning Cognitive Deficits on Neuropsychological Evaluations: Multiple Detection Strategies

Description: Individuals undergoing forensic neuropsychological evaluation frequently stand to gain in some manner if neurocognitive dysfunction is diagnosed. As a result, neuropsychologists are customarily asked to test for neurocognitive feigning during the assessment. The current study employed an analogue design with a clinical comparison group to examine the utility of the TOCA (Rogers, 1996) as a measure of feigned neurocognitive impairment. Two groups of simulators (one cautioned about the presence of detection strategies and one not cautioned) were compared to clinical and normal control groups. Fourteen scales were developed based on five detection strategies: symptom validity testing, performance curve, magnitude of error, response time, and floor effect. Each was employed during both verbal and nonverbal tasks. Significant differences were revealed among groups when subjected to ANOVA. Classification rates from subsequent utility estimates and discriminant function analyses on the scales ranged from 58.8% to 100%. Combining strategies yielded a classification rate of 95.7%. The effect of cautioning simulators was modest; however, a trend was noted on some scales for cautioned simulators to appear less obviously impaired than noncautioned. Although the results require crossvalidation, preliminary data suggest that the TOCA is a sensitive and specific measure of feigned neurocognitive performance. Strengths and weaknesses of the study are discussed and directions for future research are proposed.

High-Temperature Corrosion of Aluminum Alloys: Oxide-Alloy Interactions and Sulfur Interface Chemistry

Description: The spallation of aluminum, chromium, and iron oxide scales is a chronic problem that critically impacts technological applications like aerospace, power plant operation, catalysis, petrochemical industry, and the fabrication of composite materials. The presence of interfacial impurities, mainly sulfur, has been reported to accelerate spallation, thereby promoting the high-temperature corrosion of metals and alloys. The precise mechanism for sulfur-induced destruction of oxides, however, is ambiguous. The objective of the present research is to elucidate the microscopic mechanism for the high-temperature corrosion of aluminum alloys in the presence of sulfur. Auger electron spectroscopy (AES), low energy electron diffraction (LEED), and scanning tunneling microscopy (STM) studies were conducted under ultrahigh vacuum (UHV) conditions on oxidized sulfur-free and sulfur-modified Al/Fe and Ni3Al(111). Evaporative deposition of aluminum onto a sulfur-covered iron surface results in the insertion of aluminum between the sulfur adlayer and the substrate, producing an Fe-Al-S interface. Aluminum oxidation at 300 K is retarded in the presence of sulfur. Oxide destabilization, and the formation of metallic aluminum are observed at temperatures > 600 K when sulfur is located at the Al2O3-Fe interface, while the sulfur-free interface is stable up to 900 K. In contrast, the thermal stability (up to at least 1100 K) of the Al2O3 formed on an Ni3Al(111) surface is unaffected by sulfur. Sulfur remains at the oxide-Ni3Al(111) interface after oxidation at 300 K. During annealing, aluminum segregation to the g ¢ -Al2O3-Ni3Al(111) interface occurs, coincident with the removal of sulfur from the interfacial region. A comparison of the results observed for the Al2O3/Fe and Al2O3/Ni3Al systems indicates that the high-temperature stability of Al2O3 films on aluminum alloys is connected with the concentration of aluminum in the alloy.

The Role of Intelligent Mobile Agents in Network Management and Routing

Description: In this research, the application of intelligent mobile agents to the management of distributed network environments is investigated. Intelligent mobile agents are programs which can move about network systems in a deterministic manner in carrying their execution state. These agents can be considered an application of distributed artificial intelligence where the (usually small) agent code is moved to the data and executed locally. The mobile agent paradigm offers potential advantages over many conventional mechanisms which move (often large) data to the code, thereby wasting available network bandwidth. The performance of agents in network routing and knowledge acquisition has been investigated and simulated. A working mobile agent system has also been designed and implemented in JDK 1.2.

Differentiation of Central Auditory Processing Disorder and Attention-Deficit Hyperactivity Disorder in Children and Adolescents

Description: The purpose of this study was to determine whether or not children diagnosed with Attention-Deficit Hyperactivity Disorder (ADHD) or Central Auditory Processing Disorder (CAPD) can be distinguished from one another on the basis of both objective and subjective assessment of attention and behavior. First, children and adolescents diagnosed with ADHD, CAPD, and concomitant ADHD/CAPD were compared to participants with emotional problems on measures of attention/concentration, depression, anxiety, and parental reports of internalzing and externalizing behaviors. Overall, statistical analyses did not reveal significant differences between performances of children diagnosed with ADHD and those diagnosed with CAPD. However, clinical comparisons across groups of children diagnosed with ADHD, CAPD, comorbid ADHD/CAPD and Affective Disorders revealed condition-specific clinical profiles, thus providing some support for CAPD as a distinct clinical entity. Second, exploratory cluster analysis was performed to further investigate the relationship between ADHD and CAPD. This procedure lead to the identification of four distinct clusters. However, analyses of these clusters revealed no distinct pattern of performance for children diagnosed with either ADHD or CAPD. Rather, participants with these diagnoses were evenly distributed throughout the clusters. Additionally, no cluster clearly represented the expected clinical profile for a diagnosis of CAPD- namely, significant auditory attentional/processing problems in the absence of other attentional difficulties. Implications for the assessment and treatment of childhood attentional disorders are discussed and recommendations for future research provided.

A Behavioral Economic Analysis of Different Reinforcers: Sound-Clips Versus Points Exchangeable for Money

Description: Human operant studies frequently use points exchangeable for money as reinforcers. Some studies employ more immediately consumable reinforcers to emulate properties of food reinforcers. This study examined demand for points/money and for sound-clips to compare their economic characteristics. Across four participants, demand was often higher and less elastic for points/money than for sounds. During subsequent exposures at each response requirement, demand for sounds often decreased to a greater degree than demand for points/money. Thus, sound-clips seem less durable than points/money across prices and across repeated exposure to the same price. Response rates for points/money were often higher than for sounds, suggesting that reinforcers that generate higher response rates may be less elastic than reinforcers that generate lower response rates.

The Thematic Apperception Test: The relationship between scored fanasy aggression and aggressive behavior

Description: This study attempted to determine the relationship between fantasy aggression and behavioral aggression, and whether fantasy aggression measured by the Thematic Apperception Test is related to behavioral aggression. Participant TAT protocols from psychology clinic files were scored for fantasy aggression, and these scores were correlated with self-reported presence or absence of behavioral aggression. The scoring system used was a blend of popular aggression scales used in the 1960s and newer theory. Other variables that were examined were story length and gender in relation to the measured amount of fantasy and behavioral aggression.

Jules Massenet's Musical Prosody Focusing on His Eight Song Cycles And A Collection, Expressions Lyriques: A Lecture Recital, Together with Recitals of Selected Works of W. A. Mozart, F. Schubert, C. Debussy, R. Strauss, D. Argento, V. Bellini, J. Marx, W. Walton, C. Gounod, A. Scarlatti, G. Fauré, J. Rodrigo, H. Wolf, and Others

Description: Jules Massenet's mélodies feature a distinct vocal treatment regarding musical prosody through his eight song cycles, including Poëme d'Avril, Poëme Pastoral, Poëme du Souvenir, Poëme d'Amour, Poëme d'Hiver, Poëme d'un Soir, and Quelques Chansons Mauves, and a collection, Expressions Lyriques. These mélodies show the influence of the trend of salon music and the high-level poetry from the poetic movements of romanticism, Parnassianism, and symbolism. This study deals with Massenet's mélodies relating to the prosody idea, which is conspicuous in his vocal treatment. His melodic styles feature four distinct aspects of vocal treatment including lyrical, recitative or parlando, melodramatic, and déclamation rhythmée, and represent the idea of musical prosody of phonetic, syntactic, and semantic aspects. Massenet's other musical idioms such as harmony, form, and piano treatment, are also closely related to the prosody matter as a semantic aspect, reinforcing the poetic mood and content. In this study, each melodic style related to French versification is examined in detail. The musical analysis regarding the other musical idioms on selected examples presents the semantic feature of prosody idea. The brief review of French versification and opinions regarding the performance are included. Massenet's contribution to the genre of mélodie, with the prose melody and treatment of piano as an equal partner of voice line, is clearly demonstrated. With this contribution, Massenet should be recognized as the most influential composer to the climatic time of French mélodie led by Fauré, and Debussy, and Duparc.

The Effects of Free Play As an Instructional Tool on the Quality of Improvisation of First, Second, and Third Grade Children

Description: To look at the effect of free play on the musical improvisations of first, second and third grade children, 108 children were randomly assigned to either a control or treatment group. Subjects were tested using a researcher-designed instrument to elicit an improvisatory response. The control group then received regular music instruction (120 minutes every 2 weeks) and the treatment group received regular music instruction in conjunction with musical free play (100 minutes of instruction and 20 minutes of free play every 2 weeks). The treatment lasted 14 weeks. At the end of the treatment, all students were tested with the same testing instrument used for the pre test. Videotapes of the improvisations were submitted to three independent judges to rate for quality on a 5-point Likert scale. The change in ratings between pre and post tests were analyzed with an analysis of variance to determine if there were significant differences between the control and treatment groups. The analysis of the data revealed no significant difference in the change of ratings between control and treatment groups for the group as a whole, or for any particular grade level within the total group.

Dark Houses: Navigating Space and Negotiating Silence in the Novels of Faulkner, Warren and Morrison

Description: Poe's "The Fall of the House of Usher," as early as 1839, reveals an uneasiness about the space of the house. Most literary scholars accept that this anxiety exists and causes some tension, since it seems antithetical to another dominant motif, that of the power of place and the home as sanctuary. My critical persona, like Poe's narrator in "The House of Usher," looks into a dark, silent tarn and shudders to see in it not only the reflection of the House of Usher, but perhaps the whole of what is "Southern" in Southern Literature. Many characters who inhabit the worlds of Southern stories also inhabit houses that, like the House of Usher, are built on the faulty foundation of an ideological system that divides the world into inside(r)/outside(r) and along numerous other binary lines. The task of constructing the self in spaces that house such ideologies poses a challenge to the characters in the works under consideration in this study, and their success in doing so is dependant on their ability to speak authentically in the language of silence and to dwell instead of to just inhabit interior spaces. In my reading of Faulkner and Warren, this ideology of division is clearly to be at fault in the collapse of houses, just as it is seen to be in the House of Usher. This emphasis is especially conspicuous in several works, beginning with Faulkner's Absalom, Absalom! and its (pre)text, "Evangeline." Warren carries the motif forward in his late novels, Flood and Meet Me in the Green Glen. I examine these works relative to spatial analysis and an aesthetic of absence, including an interpretation of silence as a mode of authentic saying. I then discuss these motifs as they are operating in Toni Morrison's Beloved, and finally take Song of …

The Effects of Biofeedback on Task Performance

Description: This experiment attempted to study the effectiveness of biofeedback training on an individual's peak performance while performing a stress-provoking task. In a between subjects design 30 individual college students were divided into 2 groups. One group received auditory biofeedback and relaxation training, and the other group received no training. Both groups met the researcher for 1 hour a week for seven weeks. During each session the participant completed a ten-minute Competition and Coaction (C & C) computer software program (Shea, 1992). The biofeedback equipment recorded the physiological state of each of the participants while he/she performed the C & C task. Both groups' physiological values and C & C scores were compared using the SPSS software. The biofeedback group had statistically lower stress values than the non-biofeedback group (Schwartz, 1995). There was no statistical difference between the 2 groups' C & C scores. The STAI Y-1 and Y-2 anxiety inventories were given to each of the participants at the 1st and 7th session to examine the anxiety differences between the 2 groups. There were no statistical differences between the 2 groups' STAI scores. This study's findings show that individuals can be taught to lower their stress response while performing a computer task.

Preparation and Characterization of a Treated Montmorillonite Clay and Epoxy Nanocomposite

Description: Montmorillonite reinforced polymers are a new development in the area of nanocomposite materials. Since reinforcement of epoxy is important to the development of high strength adhesives and composite matrices, the introduction of montmorillonite to epoxy is of interest. Compositional effects on epoxy reactivity, on molecular relaxation, and on mechanical properties were investigated. Change in reactivity was determined by Differential Scanning Calorimetry. Tensile properties at room temperature indicated improved modulus and retention of strength of the epoxy matrix but a decreased elongation to failure. Depression of dry nanocomposite glass transition was observed for nanocomposites beyond 5% by weight montmorillonite. Samples that were saturated with water showed lower moduli due to the epoxy matrix. The greatest moisture absorption rate was found at 7%, the least at 3%.

Unexpected Unexpected Utilities: A Comparative Case-Study Analysis of Women and Revolutions

Description: Women have been part of modern revolutions since the American Revolution against Great Britain. Most descriptions and analyses of revolution relegate women to a supporting role, or make no mention of women's involvement at all. This work differs from prior efforts in that it will explore one possible explanation for the successes of three revolutions based upon the levels of women's support for those revolutions. An analysis of the three cases (Ireland, Russia, and Nicaragua) suggests a series of hypotheses about women's participation in revolution and its importance to revolutions' success.

Establishment and Competitive Ability of Nelumbo Lutea in Relation to Myriophyllum Spicatum

Description: Limitations from reduced light and increasing water depth on Nelumbo lutea seedlings were determined in tank experiments. Survival was high in all tested light levels. Total biomass increased significantly with increasing light. Biomass allocation shifted significantly to root production between 3 and 6 weeks in the 10 and 24% levels. Survival decreased with increasing planting depth, and biomass of survivors reduced significantly between 0.5, 1.0, and 1.5 m depths. Nelumbo lutea and Myriophyllum spicatum populations were monitored for one season in a 0.7 ha pond to track changes in species dominance. Myriophyllum spicatum dominated early, and N. lutea dominated from July through October, suppressing M. spicatum at all depths. Competitive interactions between N. lutea and M. spicatum were investigated for two seasons in a container experiment situated within a pond. Where established, N. lutea dominated in the presence of M. spicatum. However, N. lutea could not be established in depths greater than 1 meter.

Comparative Analysis of Intensive Filial Therapy with Intensive Individual Play Therapy and Intensive Sibling Group Play Therapy with Child Witnesses of Domestic Violence

Description: The purpose of this study was to determine the effectiveness of Intensive Filial Therapy in: (a) improving the self-concept of child witnesses of domestic violence; (b) reducing internalizing behavior problems, such as withdrawal, somatic complaints, anxiety and depression, of child witnesses of domestic violence; (c) reducing externalizing behavior problems, such as aggression and delinquency, of child witnesses of domestic violence; (d) reducing overall behavior problems of child witnesses of domestic violence; and (e) increasing communication of empathy between mothers and child witnesses of domestic violence. A second objective of this study was to compare the effectiveness of Intensive Filial Therapy with Intensive Individual Play Therapy and Intensive Sibling Group Play Therapy with child witnesses of domestic violence. The experimental group consisted of 11 child witnesses of domestic violence whose mothers received 12 Intensive Filial Therapy training sessions within a three week period and had 12 mother-child play sessions. The Intensive Individual Play Therapy comparison group, consisting of 11 child witnesses, and the non-treatment control group, consisting of 11 child witnesses, were utilized from the Kot (1995) study. The Intensive Sibling Group Play Therapy comparison group was utilized from the Tyndall-Lind (1999) study. Children in all studies completed the Joseph Preschool and Primary Self-concept Screening Test and the Child Behavior Checklist. Mothers who received Intensive Filial Therapy training conducted pretest and posttest play sessions for the Measurement of Empathy in Adult-Child Interaction. Analyses of Covariance revealed the children in the experimental group significantly increased in self-concept, and significantly reduced overall behavior problems. A comparison of t-test scores of the pretests and posttests revealed mothers in the experimental group significantly increased communication of empathy to their children.

The Effects of a Play Therapy Intervention Conducted by Trained High School Students on the Behavior of Maladjusted Young Children: Implications for School Counselors

Description: This research study investigated the effectiveness of a child-centered play therapy intervention conducted by trained high school students on the behavior of preschool and kindergarten children with adjustment difficulties. Specifically, this research determined if play sessions conducted by high school students trained in child-centered play therapy skills and procedures facilitated change in the children's behaviors. The experimental group children (N=14) each received 20 weekly individual play sessions from a high school student enrolled in a Peer Assistance and Leadership class. The high school students were randomly paired with a referred child. The high school students completed 7 one-hour training sessions in child-centered play therapy procedures and skills prior to beginning the weekly, supervised play sessions. The control group (N=12) received no treatment during the study. Pre and post data were collected from parents who completed the Child Behavior Checklist (CBCL) and teachers who completed the Early Childhood Behavior Scale (ECBS). Multivariate analyses of variance of gained scored revealed statistical significance in 2 of the 4 hypotheses. Specifically, the children in the experimental group showed significant decreases in internalizing behaviors (p = .025) and total behaviors (p = .025) on the CBCL. Although not in the statistically significant range, positive trends were noted in externalizing behaviors on the CBCL (p = .07) and total behaviors on the ECBS (p = .056). All play sessions were conducted in the primary school that the children attended. The high school student facilitated play sessions helped to maximize the school counselor's time by meeting the needs of more students. Implications for school counselors are noted with suggestions for how to begin and maintain a similar program in schools. This study supports the use of child-centered play therapy by trained high school students as an effective intervention for helping young children with a variety of adjustment …

A Behavioral Economic Analysis of the Demand for Money in Humans

Description: This study investigated the effects of unit price structure, unit price descriptions, and unit price sequence on the demand for money in humans. Six groups of 3 participants solved multiplication problems in exchange for money under various unit prices. Consumption of money decreased as the unit price increased across all conditions. However, the data also showed that: (a) fixed price structures produced slightly more elastic demand than did variable price structures, (b) price descriptions produced more elastic demand under variable price structures but had little or no effect under fixed price structures, and (c) the alternate sequence used with fixed price structures produced slightly more elastic demand.
