Development of a Procedure to Evaluate Groundwater Quality and Potential Sources of Contamination in the East Texas Basin
Access:
Use of this item is restricted to the UNT Community
This study contributes a procedure, based on data analysis and geostatistical methods, to evaluate the distribution of chemical ratios and differentiate natural and anthropogenic contaminant sources of groundwater quality in the East Texas Basin. Four aquifers were studied, Sparta, Queen City, Carrizo and Wilcox. In this study, Carrizo- Wilcox is considered as one aquifer, and Sparta-Queen City as another. These aquifers were divided into depth categories, 0-150 feet for Sparta-Queen City and 300-600 feet and 600-900 feet for Carrizo-Wilcox in order to identify individual sources of contamination. Natural sources include aquifer mineral make up, salt domes and lignite beds. Major anthropogenic sources include lignite and salt dome mining and oil-gas production. Chemical ratios selected were Na/Cl, Ca/Cl, Mg/Cl, SO4/Cl, (Na+Cl)/TDS, SO4/Ca and (Ca+Mg)/(Na+K). Ratio distributions and their relationships were examined to evaluate physical-chemical processes occurring in the study area. Potential contaminant sources were used to divide the Basin into three areas: Area 1 to the east, Area 2 in the west and Area 3 in the center. Bivariate analysis was used to uncover differences between the areas. The waters in Area 1 are potentially impacted primarily from oil field waters. Sources present in Area 2 include lignite beds and oil …

The Effect of Faculty Development on Active Learning in the College Classroom
Access:
Use of this item is restricted to the UNT Community
This study examined the effect of active learning seminars and a mentoring program on the use of active learning teaching techniques by college faculty. A quasi-experimental study was conducted using convenience samples of faculty from two private Christian supported institutions. Data for the study were collected from surveys and faculty course evaluations. The study lasted one semester. Faculty volunteers from one institution served as the experimental group and faculty volunteers from the second institution were the comparison group. The experimental group attended approximately eight hours of active learning seminars and also participated in a one-semester mentoring program designed to assist faculty in application of active learning techniques. Several individuals conducted the active learning seminars. Dr. Charles Bonwell, a noted authority on active learning, conducted the first three-hour seminar. Seven faculty who had successfully used active learning in their classrooms were selected to conduct the remaining seminars. The faculty-mentoring program was supervised by the researcher and conducted by department chairs. Data were collected from three surveys and faculty course evaluations. The three surveys were the Faculty Active Learning Survey created by the researcher, the Teaching Goals Inventory created by Angelo and Cross, and the college edition of Learner-Centered Practices by Barbara …

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

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

Feigning Cognitive Deficits on Neuropsychological Evaluations: Multiple Detection Strategies
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 …

Equivalency of paper-pencil tests and computer-administered tests.
Access:
Use of this item is restricted to the UNT Community
Are computer-administered versions of a multiple choice paper-pencil test equivalent? This study determined whether there were any significant differences between taking a traditional pencil-paper test and taking the same test using a computer. The literature has shown that there are intervening variables that have caused differences when not controlled. To prove equivalency between test modes, scores have to have similar means, dispersions, and shapes; the ranked-order of the scores must also be similar. Four tests were given over the course of a 16-week semester. The sample was divided, half taking paper-pencil tests and half taking the same test administered by a computer. The mode of administration was switched with each test administration. The analysis showed that, when the intervening variables were controlled, the two modes of administration were equivalent. The analysis used a 2x4 ANOVA, which showed no difference between test modes, but showed that each test administration was significantly different. The Levene statistic was used to test whether dispersions were equivalent and confidence intervals were established to test the kurtosis and skewness statistics. Finally, each of the test scores were transformed into their Normal Curve Equivalents so that Pearson's coefficient could be used to determine the equivalency of the …

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

Teen ages: Youth market romance in Hollywood teen films of the 1980s and 1990s
Access:
Use of this item is restricted to the UNT Community
This thesis examines the differences between teen romantic comedy films marketed to Generation X teenagers in the 1980s and Generation Y teenagers in the 1990s, focusing on the presentation of gender roles, consumptive behavior, and family. The 1980s films are discussed within the social context of the Reagan era and the conservatism of the New Right. The 1990s films are examined as continuing a conservative sensibility, but they additionally posit consumption as instrumental to achieving an idealized romance. Romantic comedy is traditionally a conservative genre, but these films illustrate female liberation through consumption. The source of difference between the cycles of teen romantic comedy is attributed to the media's attempt to position Generation Y teenagers as ideal consumers.

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
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 …

Use of this item is restricted to the UNT Community
Using data from the Household Component of the 1996 Medical Expenditure Panel Survey, the study compares (1) the accessibility, and (2) the predictors of health care services utilization among African American and non-Hispanic White males, 18 to 65 years old in the United States. Using ANOVA procedure in comparing the means for use of physicians, hospitals, doctors, and difficulty obtaining care, seven hypotheses were tested in the study. First, it was hypothesized that African American men of working age will have less access to health care services (physicians, hospitals, and dentists), and be more likely to report having experienced delay or difficulty obtaining care, compared to non-Hispanic white males of working age. Second, it was hypothesized that, controlling for health status, African American men of working age will have less access to health care services (physicians, hospitals, and dentists), and will also be more likely to experience delay or difficulty obtaining care, than non-Hispanic white males. This was followed by the third hypothesis which compared utilization of physicians, hospitals, dentists, and difficulty obtaining care among African American and non-Hispanic white males, controlling for health status and insurance coverage (any insurance, private insurance, any public insurance, and Medicaid).

Analysis of the Impact of CACREP Accreditation of Counselor Education Programs on Student Knowledge Outcomes
Access:
Use of this item is restricted to the UNT Community
The principal investigator (PI) for this study analyzed mean scores on the National Counselor Examination (NCE) of students from CACREP accredited and non- CACREP accredited programs. Data was provided by the National Board of Certified Counselors, Inc., for a total of ten examination administrations across six years. The fourteen variables examined in the study consisted of the eight common-core knowledge domains identified in CACREP standards, the five counselor work behavior areas identified by NBCC via periodic job analysis of counseling practice, and one overall or total score on the NCE. NCE mean scores of students from CACREP accredited programs were higher than NCE mean scores of students from non-CACREP accredited programs on all variables across all ten NCE administrations. Data seem to indicate that students from CACREP accredited programs perform significantly better on the NCE than students from non-CACREP accredited programs, in all fourteen variables. Sample size was large, totaling 9707, so the PI calculated effect sizes using Cohen's d for each variable to aid interpretation of statistical significance. Five variables had large effect sizes of .70 or higher. The higher effect size statistics were associated with the counselor work behavior areas, with the highest effect size (.85) associated with …

Temporally Correct Algorithms for Transaction Concurrency Control in Distributed Databases
Access:
Use of this item is restricted to the UNT Community
Many activities are comprised of temporally dependent events that must be executed in a specific chronological order. Supportive software applications must preserve these temporal dependencies. Whenever the processing of this type of an application includes transactions submitted to a database that is shared with other such applications, the transaction concurrency control mechanisms within the database must also preserve the temporal dependencies. A basis for preserving temporal dependencies is established by using (within the applications and databases) real-time timestamps to identify and order events and transactions. The use of optimistic approaches to transaction concurrency control can be undesirable in such situations, as they allow incorrect results for database read operations. Although the incorrectness is detected prior to transaction committal and the corresponding transaction(s) restarted, the impact on the application or entity that submitted the transaction can be too costly. Three transaction concurrency control algorithms are proposed in this dissertation. These algorithms are based on timestamp ordering, and are designed to preserve temporal dependencies existing among data-dependent transactions. The algorithms produce execution schedules that are equivalent to temporally ordered serial schedules, where the temporal order is established by the transactions' start times. The algorithms provide this equivalence while supporting currency to the …

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

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

Epoxy + Liquid Crystalline Epoxy Coreacted Networks
Molecular reinforcement through in-situ polymerization of liquid crystalline epoxies (LCEs) and a non-liquid crystalline epoxy has been investigated. Three LCEs: diglycidyl ether of 4,4'-dihydroxybiphenol (DGE-DHBP) and digylcidyl ether of 4-hydroxyphenyl-4"-hydroxybiphenyl-4'-carboxylate (DGE-HHC), were synthesized and blended with diglycidyl ether of bisphenol F (DGEBP-F) and subsequently cured with anhydride and amine curing agents. Curing kinetics were determined using differential scanning calorimetry (DSC). Parameters for autocatalytic curing kinetics of both pure monomers and blended systems were determined. The extent of cure for both monomers was monitored by using Fourier transform infrared spectroscopy (FT-IR). The glass transitions were evaluated as a function of composition using DSC and dynamic mechanical analysis (DMA). The results show that the LC constituent affects the curing kinetics of the epoxy resin and that the systems are highly miscible. The effects of molecular reinforcement of DGEBP-F by DGE-DHBP and DGE-HHC were investigated. The concentration of the liquid crystalline moiety affects mechanical properties. Tensile, impact and fracture toughness tests results are evaluated. Scanning electron microscopy of the fracture surfaces shows changes in failure mechanisms compared to the pure components. Results indicate that mechanical properties of the blended samples are improved already at low concentration by weight of the LCE added into …

The Four Major Education GI Bills: A Historical Study of the Shifting National Purposes and Accompanying Changes in Economic Value to Veterans
Benefits for soldiers follow the formation of ancient and present day armies raised for the purpose of extending the national or state will. Veterans' benefits for defenders of the U.S. emerged during the American colonial period. College benefits began after WWII with the GI Bill of Rights. This study examines the variations in purpose for nationally established educational benefits for veterans and the singular value to the veterans of these 5educational benefits. The study begins with an overview of the history of veterans' benefits. Primary emphasis is then placed on the educational portion of the World War II Servicemen's Readjustment Act and the current educational benefit, the Montgomery GI Bill. As the purpose of awarding educational benefits changed from World War II to the latest U.S. war, the Gulf War of 1990-1991, the economic value to the individual veteran also changed. The WWII GI Bill featured an educational provision intended to keep returning veterans out of the changing economy whereas current GI Bills is intended as a recruiting incentive for an all-volunteer force. Correspondingly, the economic value to the individual veteran has changed. Data supporting this study were extracted from historical documents in primary and secondary scholarly studies and writings, …

The Relationship Among Teacher Expectations, Teacher Attitudes Toward the TAAS, and Student Achievement
Accountability is a major issue in education and in Texas, the TAAS test is used to indicate performance of students, teachers, campuses, and districts. The stakes are high for students, as performance on this test has determined whether they progress to another grade and whether they will receive a diploma. Most research studies focus on relationships between the teacher and individual students or groups of students, but not classrooms. Expectations and high stakes testing are central within the educational process, and their relationship on student achievement should be investigated, especially since no studies on teacher attitudes toward the TAAS test have been found. This correlational study measured teacher attitudes toward the TAAS and teacher expectations for students through data collected from a survey. Student achievement information was collected from averaged Texas Learning Index scores for students by classroom over a two year period. The sample consisted of 22 4th, 8th, and 10th grade reading and/or math teachers who had taught in the same Texas mid-sized, rural school district for at least two years. Frequency, percent, mean, and standard deviation were used to analyze the responses on the survey.

Psychometric Development of the Adaptive Leadership Competency Profile
This study documented the psychometric development of the Adaptive Leadership Competency Profile (ALCP). The ALCP was derived from a qualitative database from the National Science Foundation project (NSF 9422368) and the academic body of literature. Test items were operationalized, and subject matter experts validated 11 macro-leadership competencies and 65 items. Rasch rating scale measurement models were applied to answer the following questions: (a) How well do the respective items of the ALCP fit the Rasch rating scale measurement model for the 11 scales of the ACLP? (b) How well do the person's abilities fit the Rasch rating scale measurement model, using the 11 scales of the ALCP? (c) What are the item separation and reliability coefficients for the 11 ALCP scales? (d) What are the person separation and reliability coefficients for the 11 ALCP scales? This study also sought to discern whether the ALCP could predict leader effectiveness as measured by the likelihood ratio index and frequency of correct predictions indices. The WINSTEPS and LIMDEP programs were used to obtain Rasch calibrations and probit estimates, respectively. The ALCP profiles the frequency and intensity of leadership behavior. Composite measures were calculated and used to predict leadership effectiveness. Results from this study …

Assessment of the Effects of Interpersonal Openness and Coping Resources on the Psychological Sequelae of Traumatic Victimization
The present study tested a model addressing whether interpersonal Openness and interpersonal and intrapersonal Coping Resources mediated the relationship between interpersonal Victimization and the Psychological Symptoms women experience as a result of these traumas. Victimization indicators (physical violence, sexual assault, psychological abuse, and revictimization), Coping indicators (optimism, self-esteem, private self-consciousness, social network and therapy), Openness indicators (self-silencing, communal orientation, trust, self-monitoring, and network orientation), and Psychological Symptoms indicators (global distress, dissociation, and suicidal ideation) were examined separately for African American (n = 245), Euro-American (n = 185), and Mexican American (n = 202) women. Structural Equation Modeling revealed that for African American and Euro-American women, Openness partially mediated the victimization-distress relationship. The model for Mexican Americans was the most complex with Openness and intrapersonal Coping fully mediating the psychological effects of victimization. Approximately 50% of the variance in psychological symptoms resulting from victimization was predicted by this model for African American and Euro-American women; over 80% of the variance was predicted for Mexican Americans. Thus, the importance of Openness to relationships in alleviating the psychological sequelae following interpersonal victimization was underscored by the results. Similarities and differences between these models are discussed. Implications of the results for future research and …

Concurrent Validity of the Wide Range Assessment of Memory and Learning and the Woodcock-Johnson Tests of Cognitive Ability-Revised with a Neurologically Compromised Pediatric Population
The Wide Range Assessment of Memory and Learning (WRAML) is a relatively new instrument used in the assessment of memory in children. The purpose of this study was to examine the validity of the WRAML by comparing the performance of children on both the WRAML and the Woodcock-Johnson Tests of Cognitive Ability- Revised (WJTCA-R). Subjects for the study were children in treatment for a brain tumor at a regional children's medical center. Fifty children participated in the study ranging from ages 6 to 17. A multiple regression analysis was conducted to determine which of four selected clusters from the WJTCA-R would have the highest correlation with the Verbal Memory Index (VERI) from the WRAML. The Short-Term Memory (GSM) cluster had the highest correlation ( r = .82) as predicted. A Pearson's product-moment correlational analysis was conducted between the Visual Processing (GV) cluster from the WJTCA-R and the Visual Memory Index (VISI) from the WRAML. GV was found to have a high positive correlation ( r = .63) with VISI. A similar analysis was conducted between the Long-Term Retrieval (GLR) cluster from the WJTCA-R and the Learning Index (LRNI) from the WRAML. GLR was found to have a high positive correlation …

Training family therapists to work with families with young children: Current practices in accredited family therapy programs and recommendations for the future
This study examined how current family counseling/therapy programs train students to work with families with young children and made recommendations for training in this area based on recommendations of child and family therapy experts and the research and clinical literature. These recommendations explored what knowledge and skills all students should acquire versus students who want to specialize with this population. Changes to accreditation standards were also proposed as well as a description of resources to support changes in program curricula. Current training was measured by examining curricula from master's level marriage and family counseling/therapy programs accredited by the Commission on Accreditation for Marriage and Family Therapy Education (COAMFTE) and the Council for Accreditation of Counseling and Related Education Programs (CACREP) and master's level social work programs with a family-related concentration accredited by the Council on Social Work Education Commission on Accreditation (CSWE), the accreditation standards from these three organizations, course syllabi from the COAMFTE and CACREP programs, and surveys of COAMFTE and CACREP program directors (60% response rate). Recommendations for training were obtained through a qualitative analysis of quotations from the literature concerning training and through interviews of child and family therapy experts (65% response rate).
