The Effects of Extinction on Human Performance Following Exposure to Fixed Ratio Schedules of Reinforcement

The Effects of Extinction on Human Performance Following Exposure to Fixed Ratio Schedules of Reinforcement

Date: May 2000
Creator: Anderson, Richard L.
Description: This experiment examined the effects of extinction on rate of responding and several topographical and temporal measures in adult humans. Three college students were trained to type the sequence 1•5•3 on a numeric keypad on a computer. The subjects were exposed to different fixed-ratio schedules of reinforcement (FR1, FR 5, and FR10 respectively) and extinction. Subjects displayed typical schedule performances during the maintenance phase of the experiment. During extinction the performances were disrupted, they showed a "break and run" pattern and a general decrease in responding. Also, new topographical and temporal patterns emerged. These data are consistent with those reported for non-human species and special human populations.

An Analytical Study of the Variations on the Theme of Paganini's Twenty-Fourth Caprice, Op. 1 by Busoni, Friedman, and Muczynski

An Analytical Study of the Variations on the Theme of Paganini's Twenty-Fourth Caprice, Op. 1 by Busoni, Friedman, and Muczynski

Date: May 2000
Creator: Ahn, Kwang Sun
Description: The purpose of this study is to analyze sets of variations on Paganini's theme by three twentieth-century composers: Ferruccio Busoni, Ignaz Friedman, and Robert Muczynski, in order to examine, identify, and trace different variation techniques and their applications. Chapter 1 presents the purpose and scope of this study. Chapter 2 provides background information on the musical form "theme and variations" and the theme of Paganini's Twenty-fourth Caprice, Op. 1. Chapter 2 also deals with the question of which elements have made this theme so popular. Chapters 3,4, and 5 examine each of the three sets of variations in detail using the following format: theme, structure of each variation, harmony and key, rhythm and meter, tempo and dynamics, motivic development, grouping of variations, and technical problems. Chapter 6 summarizes the findings from this study and attempts to compare those elements among the three variations. Special attention is given to the application of the motivic cells, which are drawn from the original Paganini theme, in the development of succeeding variations. This study shows how these motivic cells contribute to the construction of new motives and melodies in each variation. Additionally, this study attempts to examine each composer's efforts in expanding variation procedure ...

Infinite Planar Graphs

Infinite Planar Graphs

Date: May 2000
Creator: Aurand, Eric William
Description: How many equivalence classes of geodesic rays does a graph contain? How many bounded automorphisms does a planar graph have? Neimayer and Watkins studied these two questions and answered them for a certain class of graphs. Using the concept of excess of a vertex, the class of graphs that Neimayer and Watkins studied are extended to include graphs with positive excess at each vertex. The results of this paper show that there are an uncountable number of geodesic fibers for graphs in this extended class and that for any graph in this extended class the only bounded automorphism is the identity automorphism.

Beyond the Human Voice: Francis Poulenc's Psychological Drama La Voix humaine (1958)

Beyond the Human Voice: Francis Poulenc's Psychological Drama La Voix humaine (1958)

Date: May 2000
Creator: Beard, Cynthia C.
Description: Francis Poulenc's one-character opera La Voix humaine (1958), a setting of the homonymous play by Jean Cocteau, explores the psychological complexities of an unnamed woman as she experiences the end of a romantic relationship. During the forty-minute work, she sings in a declamatory manner into a telephone, which serves as a sign of the unrevealed man at the other end. Poulenc uses musical motives to underscore the woman's changing emotional states as she recalls her past relationship. The musical dramaturgy in this work resignifies Debussy's impressionist symbolism by collapsing devices used in Pelléas et Mélisande in a language that shifts between octatonicism, chromaticism, harmonic and melodic whole tone passages, and diatonicism. This late work recontextualizes elements in Poulenc's Dialogues des Carmélites (1953-56), and the end of the opera provides a theme for his Sonate pour Clarinet et Piano(1962), as Poulenc reflects on his youthful encounters with Cocteau, Erik Satie, and Les Six.

Husband's and Daughter's Role Strain During Breast Cancer Hospice Patient Caregiving and Bereavement Adjustment

Husband's and Daughter's Role Strain During Breast Cancer Hospice Patient Caregiving and Bereavement Adjustment

Date: May 2000
Creator: Bernard, Lori Lynn
Description: Current literature regarding caregiver bereavement adjustment has advanced two competing models explaining adjustment in relation to caregiver interrole conflict: the Relief Model and Complicated Grief Model. This research has primarily focused on the experience of those providing care to dementia patients. This study tests these competing models of bereavement adjustment for husband and daughter caregivers of breast cancer hospice patients. For husbands, greater psychological strain and health strain were predictive of greater difficulty with bereavement adjustment, supporting the Complicated Grief Model of bereavement adjustment. For daughters, strain was not a significant predictor of bereavement adjustment, and thus did not support either bereavement adjustment model. While daughter caregivers experienced more role strain than husband caregivers during patient care, the degree of role strain was predictive of bereavement adjustment for husbands but not for daughters, suggesting that relationship type (husbands versus daughters) between caregiver and patient impacts which factors influence bereavement adjustment.

The Effect of Three Different Levels of Skill Training in Musical Timbre Discrimination on Alphabet Sound Discrimination in Pre-Kindergarten and Kindergarten Children

The Effect of Three Different Levels of Skill Training in Musical Timbre Discrimination on Alphabet Sound Discrimination in Pre-Kindergarten and Kindergarten Children

Date: May 2000
Creator: Battle, Julia Blair
Description: The purpose of this study was to investigate the effects of three different levels of skill training in musical timbre discrimination on alphabet sound discrimination in pre-kindergarten and kindergarten children. The findings of prior investigations indicated similarities between aural music and language perception. Psychoacoustic and neurological findings have reported the discrimination of alphabet quality and musical timbre to be similar perceptual functions and have provided, through imaging technology, physical evidence of music learning simultaneously stimulating non-musical areas of the brain. This investigator hypothesized that timbre discrimination, the process of differentiating the characteristic quality of one complex sound from another of identical pitch and loudness, may have been a common factor between music and alphabet sound discrimination. Existing studies had not explored this relationship or the effects of directly teaching for transfer on learning generalization between skills used for the discrimination of musical timbre and alphabet sounds. Variables identified as similar from the literature were the discrimination of same- different musical and alphabet sounds, visual recognition of musical and alphabet pictures as sound sources, and association of alphabet and musical sounds with matching symbols. A randomized pre-post test design with intermittent measures was used to implement the study. There were 5 ...

Linearity and monotonicity of a 10-bit, 125 MHz, segmented current steering digital to analog converter

Linearity and monotonicity of a 10-bit, 125 MHz, segmented current steering digital to analog converter

Date: May 2000
Creator: Bittle, Charles C.
Description: The purpose of this research is to determine the linearity and monotonicity of the THS5651IDW digital to analog converter (DAC), a prototype of the future Texas Instruments TLV5651, 10-bit, 125 MHz communication DAC. Testing was conducted at the Texas Instruments facility on Forest Lane, Dallas, Texas. Texas Instruments provided test equipment, software and laboratory space to obtain test data. Analysis of the data found the DAC to be monotonic since the magnitude of the differential nonlinearity (DNL) was less than ± 1 least significant bit (LSB) and the integral nonlinearity (INL) was less than ± 0.5 LSB. The study also showed that the DAC has primarily negative DNL although the DNL is well within the desired specification.

Oxygen Uptake Kinetics in Severe Intensity Exercise

Oxygen Uptake Kinetics in Severe Intensity Exercise

Date: May 2000
Creator: Blumoff, Sonja
Description: The purpose of this study was to describe mathematically the oxygen uptake kinetics during cycle ergometry, and to examine the effect of intensity on the kinetic responses within the severe domain. Sixteen volunteers performed a series of exercise tests at a range of intensities selected to elicit fatigue in ~3 to 10 min. A simple mono-exponential model effectively described the response across all intensities. There was a positive correlation between the response time and the time to fatigue, demonstrating that the maximal oxygen uptake was achieved faster at higher intensities within the severe domain. Models incorporating two components effectively described the responses only in tests lasting 8 min or more. It was concluded that there is a second, slow component in the oxygen uptake response only at the lower intensities within the severe domain.

Filial Therapy Training with Undergraduate Teacher Trainees; Child-Teacher Relationship Training

Filial Therapy Training with Undergraduate Teacher Trainees; Child-Teacher Relationship Training

Date: May 2000
Creator: Brown, Christopher J.
Description: This experimental research study investigated the effectiveness of the application of Child-Teacher Relationship training, adapted from child-centered play therapy procedures and skills training (filial therapy), with undergraduate teacher trainees. Specifically, this research determined if Child-Teacher Relationship training facilitated change in teacher trainees' interactions with children, parenting attitudes, and play therapy attitude knowledge and skills. The experimental group of teacher trainees (n=18) received 10 weekly ninety minute training sessions in child-centered play therapy skills and procedures and conducted 7 weekly special play times with children. The comparison group (n=20) received supplemental training in child guidance during the ten weeks that included parent training and alternatives to corporal punishment. Experimental and comparison group participants completed pre-test and post-test measures, consisting of the Adolescent and Adult Parenting Attitudes Inventory (AAPI-2), the Play Therapy Attitudes, Knowledge, and Skills Survey (PTAKSS), and a videotaped special play time with a child which was rated using the Measurement of Empathy in Adult and Child Interactions (MEACI). Analysis of covariance on adjusted post test means revealed that the teacher trainees in the experimental group demonstrated statistically significant ("<.05) increases in empathy towards children, allowing the child self direction, communication of acceptance, and involvement as measured by the MEACI. ...

Prediction of Community College Students' Success in Developmental Math with Traditional Classroom, Computer-Based On-Campus and Computer-Based at a Distance Instruction Using Locus of Control, Math Anxiety and Learning Style

Prediction of Community College Students' Success in Developmental Math with Traditional Classroom, Computer-Based On-Campus and Computer-Based at a Distance Instruction Using Locus of Control, Math Anxiety and Learning Style

Date: May 2000
Creator: Blackner, Deborah Martin
Description: The purpose of this study was to investigate the relationship between individual student differences and academic success in three pedagogical methods (traditional classroom, computer-aided instruction (CAI) in an on-campus setting, and CAI in a distance education setting) for developmental mathematics classes at the community college level. Locus of control, math anxiety and learning style were the individual differences examined. Final grade, final exam score and persistence were the indicators of success. The literature review focused on developmental mathematics, pedagogical techniques and variables contributing to academic performance. Two parallel research populations consisted of 135 Beginning Algebra students and 113 Intermediate Algebra students. The Rotter I-E Locus of Control Scale, the Abbreviated Mathematics Anxiety Rating Scale, the 4MAT Learning Type Measure, and an instrument to gather demographic data were used. It was the conclusion of this study that the instructional methods were not equal with respect to achievement. In Beginning Algebra, the CAI students received significantly higher final grades than did the traditionally taught students. In Intermediate Algebra traditional students scored significantly higher on the final exam than did the CBI students. There were more students persisting than expected in traditionally taught Beginning Algebra and no significant difference in attrition in Intermediate ...

Effects of a Simulation Game on Trainees' Knowledge and Attitudes About Age-related Changes in Learning and Work Behaviors of Older Workers

Effects of a Simulation Game on Trainees' Knowledge and Attitudes About Age-related Changes in Learning and Work Behaviors of Older Workers

Date: May 2000
Creator: Dunn, Suzanne
Description: This investigation was conducted in response to the need for effective diversity awareness programs to help employers create intergenerational-friendly work environments. An experimental pre- and post-test control group randomized block design was employed to answer two research questions about the effects of a simulation game on knowledge and attitudes about age-related changes in learning and work behaviors of older workers. Participants were assessed immediately prior to and following the treatment, followed by a third assessment 60 days later. Necessary measures were taken to control for threats to the study's internal validity. An applicant pool comprised of human resource management and development practitioners and senior undergraduate students enrolled in human resource management courses yielded a sample of 65 participants. Chapter one introduces the study. Chapter two provides a review and summary of relevant literature on ageism in the workplace, training older workers, and simulation games. Chapter three describes the procedures and methods used to answer the research questions. Chapter four presents the results of all analytic procedures related to the investigation. Chapter five provides the conclusions and recommendations based on the findings of this investigation. In this investigation, the treatment group did not score significantly higher on their knowledge of age-related ...

What insight do market participants gain from dividend increases?

What insight do market participants gain from dividend increases?

Date: May 2000
Creator: Ellis, R. Barry
Description: This study examines the reactions of market makers and investors to large dividend increases to identify the motives for dividend increases. Uniquely, this study simultaneously tests the signaling and agency abatement motivations as explanations of the impact of dividend increases on stock prices and bid-ask spreads. The agency abatement hypothesis argues that increased dividends constrict management's future behavior, abating the agency problem with shareholders. The signaling hypothesis asserts that dividend increases signal that managers expect higher or more stable cash flows in the future. Mean stock price responses to dividend increase announcements during 1995 are examined over both short ( _1, 0) and long ( _1, 504) windows. Changes in bid-ask spreads are examined over a short ( _1, 0) window and an intermediate (81 day) period. This study partitions dividend increases into a sample motivated by agency abatement and a sample motivated by cash flow signaling. Further, this study examines the agency abatement and cash flow signaling explanations of relative bid-ask spread responses to announcements of dividend increases. Estimated generalized least squares models of market reactions to sampled events support the agency abatement hypothesis over the cash flow signaling hypothesis as a motive for large dividend increases as measured ...

An Examination Of The Variation In Information Systems Project Cost Estimates: The Case Of Year 2000 Compliance Projects

An Examination Of The Variation In Information Systems Project Cost Estimates: The Case Of Year 2000 Compliance Projects

Date: May 2000
Creator: Fent, Darla
Description: The year 2000 (Y2K) problem presented a fortuitous opportunity to explore the relationship between estimated costs of software projects and five cost influence dimensions described by the Year 2000 Enterprise Cost Model (Kappelman, et al., 1998) -- organization, problem, solution, resources, and stage of completion. This research was a field study survey of (Y2K) project managers in industry, government, and education and part of a joint project that began in 1996 between the University of North Texas and the Y2K Working Group of the Society for Information Management (SIM). Evidence was found to support relationships between estimated costs and organization, problem, resources, and project stage but not for the solution dimension. Project stage appears to moderate the relationships for organization, particularly IS practices, and resources. A history of superior IS practices appears to mean lower estimated costs, especially for projects in larger IS organizations. Acquiring resources, especially external skills, appears to increase costs. Moreover, projects apparently have many individual differences, many related to size and to project stage, and their influences on costs appear to be at the sub-dimension or even the individual variable level. A Revised Year 2000 Enterprise Model is presented incorporating this granularity. Two primary conclusions can ...

Spatial and Temporal Influences of Water Quality on Zooplankton in Lake Texoma

Spatial and Temporal Influences of Water Quality on Zooplankton in Lake Texoma

Date: May 2000
Creator: Franks, Jessica L.
Description: Seventy-one aquatic species including the copepodids and nauplii were identified from Lake Texoma from August 1996 to September 1997. Zooplankton community structure, abundance and spatial and temporal distributions were compared among five lake zones delineated a priori based on chloride concentration. The zones, in order of decreasing chloride concentration, are the Red River zone (RRZ), Red river Transition zone (RRTZ), Main Lake zone (MLZ), Washita River Transition zone (WRTZ) and Washita River zone (WRZ). Bray Curtis Similarity Index showed community structure was most similar in the two Red River arm zones, the two Washita River arm zones and the MLZ. Zooplankton abundance was greatest in the Red River arm (312 org/L), intermediate in the Washita River arm (217 org/L) and least in the Main Lake body (103 org/L). A significant increase in the abundance of a deformed rotifer, Keratella cochlearis, was observed mainly in the Red River arm during a second study from March 1999 to June 1999. Seasonal dynamics, rather than spatial dynamics, were more important in structuring the zooplankton community, especially in the two river arms. Spatial variance was solely attributed to station and zone effects independent of time for a few crustacean species and many of the ...

Comparative Models of the Impact of Social Support on Psychological Distress in Cancer Patients

Comparative Models of the Impact of Social Support on Psychological Distress in Cancer Patients

Date: May 2000
Creator: Forjaz, Maria João Bettencourt Pereira
Description: This study tested the relationship between Social Support, Psychological Distress, and Illness Stress in individuals who report cancer as a health condition. This study was based on archival data obtained from the Wave 1 of the Health and Retirement Study (HRS). The HRS provides a nationally representative sample of individuals aged 51 to 61 in 1992 and their spouses. The study sample was limited to cancer patients with a spouse or partner (n = 503). A structural equation modeling analysis procedure was used to test the theoretical models. Measures of social support were limited to variables assessing the participant's satisfaction with social support. Evidence was found for the Stress Prevention and the Support Deterioration models. This is congruent with previous research using measures of social support perception. Both the Stress Prevention and the Support Deterioration models predict a negative relationship between Illness Stress and Social Support. In addition, a univariate analysis of variance was used to test the stress buffering model. Similarly to other studies measuring the individual's degree of integration, or its perception, in the social network, the present research supported the only the Main Effect model and not the Stress Buffering model.

Images of Remembered Earth

Images of Remembered Earth

Date: May 2000
Creator: Floyd, James Michael
Description: Images of Remembered Earth is a musical composition scored for full orchestra. The composition was inspired by Georgia O'Keeffe's painting, Light Coming on the Plains I (1917), which depicts a sunrise over a flat and empty landscape. In the painting, the expanse of the sun's rays is expressed through an even-blended transformation of color from goldish-blue at the light's source to progressively darker shades of blue near the edges of the canvas. The progression of color is interrupted by thin gold bands which sectionalize the sunrise into seven concentric arches. The construction of the musical composition derives musical materials directly from elements found within O'Keeffe's painting, specifically the shaping of structure, expansion, and color in arch patterns. Arch patterns, an integral element in O'Keeffe's painting, govern elements in the musical composition, including pitch selection, the overall tempo scheme, rhythmic activity, and formal shape. Pitch materials are expansive by design; this expansive quality is exhibited through the employment of wedge-shaped musical ideas and through the utilization of higher and lower registers. O'Keeffe's use of color in the painting influenced the orchestration of the music and is manifested in two ways: 1) gradual transformation of timbral colors and 2) the juxtaposition of ...

Effectiveness of a Child-Centered Self-Reflective Play Therapy Supervision Model

Effectiveness of a Child-Centered Self-Reflective Play Therapy Supervision Model

Date: May 2000
Creator: Giordano, Maria A.
Description: This study investigated the effectiveness of a child-centered self-reflective play therapy supervision model with master's level counselor education graduate students. Specifically, this research determined if the self-reflective play therapy supervision model facilitated significant change in the master's level play therapists': (a) child-centered attitude; (b) knowledge of child-centered play therapy; and (c) confidence in applying play therapy skills. This study also measured change in the skills of: (d) tracking behavior, (e) reflecting content, (f) reflecting feelings, (g) facilitating decision-making and self-responsibility, (h) facilitating esteem-building and encouragement, (i) encouraging the child to lead, (j) setting limits, (k) ability to be congruent, (l) quality of non-verbal responses and (m) quality of verbal responses. The experimental group students (N=15) utilized a 15 week self-reflective play therapy supervision model. This model consisted of a manual that reviewed the rationale and utilization of six therapeutic responses of child-centered play therapy, self-assessment forms that were completed after reviewing weekly play therapy session videos and weekly group supervision. The control group (N=15) received supervision during the 15 weeks but did not use the manual or the self-assessment forms. Prior to working with their first client and again at the end of the semester practicum, the play therapy supervisees ...

Measuring attention: An evaluation of the Search and Cancellation of Ascending Numbers (SCAN) and the short form of the Test of Attentional and Interpersonal Style (TAIS)

Date: May 2000
Creator: Greher, Michael R.
Description: This study found a relationship between the Search and Cancellation of Ascending Numbers (SCAN), Digit Span, and Visual Search and Attention Test (VSAT). Data suggest the measures represent a common construct interpreted to be attention. An auditory distracter condition of the SCAN did not distract participants, while the measure exhibited ample alternate forms reliability. The study also found that the Test of Attentional and Interpersonal Style (TAIS) short form poorly predicted performance on the Digit Span, VSAT, and SCAN. Although the TAIS exhibited good internal consistency, the items likely measure the subjective perception of attention. Furthermore, discriminant and convergent validity of the TAIS were found to be poor.

Redemption and the Other: The Supernatural Narrator and the Intertextual (Sub)version of the Miltonic Command

Redemption and the Other: The Supernatural Narrator and the Intertextual (Sub)version of the Miltonic Command

Date: May 2000
Creator: Gowdy, Robert Douglas
Description: In literary discourse from the Genesis creation myth through John Milton's Paradise Lost and beyond, Eve has been patriarchally considered to be the bringer of Sin and Death into the world. In Paradise Lost Eve is depicted as deceiving Adam into the Fall by way of the Serpent. Paradise Lost creates a Miltonic command that helps to further blame Woman for Sin and Death. Milton's poem is based on the Genesis creation myth written by Canaanite authors. In this myth the Canaanite authors wished to rid the world of Goddess worship and, by humanizing Eve, they successfully obliterate that form of worship. As a result of this obliteration of the Goddess, Eve, as a humanized form of the ancient Goddess Asherah, remains unredeemed for her sin and forever held to blame. Throughout what Michel Foucault calls the archive, or discourse in which power resides, Eve/Woman continues to be seen by patriarchal discourse as to blame for the Fall. There has never been a successful redemption for Eve in the archive. Although Samuel Richardson's Clarissa has been suggested as a successful redeemer of Eve, Clarissa's blatant will to death and, therefore, will to power precludes a successful redemption of Eve. The ...

MEDLINE Metric: A method to assess medical students' MEDLINE search effectiveness

MEDLINE Metric: A method to assess medical students' MEDLINE search effectiveness

Date: May 2000
Creator: Hannigan, Gale G.
Description: Medical educators advocate the need for medical students to acquire information management skills, including the ability to search the MEDLINE database. There has been no published validated method available to use for assessing medical students' MEDLINE information retrieval skills. This research proposes and evaluates a method, designed as the MEDLINE Metric, for assessing medical students' search skills. MEDLINE Metric consists of: (a) the development, by experts, of realistic clinical scenarios that include highly constructed search questions designed to test defined search skills; (b) timed tasks (searches) completed by subjects; (c) the evaluation of search results; and (d) instructive feedback. A goal is to offer medical educators a valid, reliable, and feasible way to judge mastery of information searching skill by measuring results (search retrieval) rather than process (search behavior) or cognition (knowledge about searching). Following a documented procedure for test development, search specialists and medical content experts formulated six clinical search scenarios and questions. One hundred and forty-five subjects completed the six-item test under timed conditions. Subjects represented a wide range of MEDLINE search expertise. One hundred twenty complete cases were used, representing 53 second-year medical students (44%), 47 fourth-year medical students (39%), and 20 medical librarians (17%). Data related ...

Creator: Hayashi, Adam
Description: The effects of three oral dosages (0.4 mg, 0.8 mg, and 1.6 mg) of quercetin on Colon-25 tumors implanted in Balb-c mice were studied. The data in this study show that: (1) certain dosages of quercetin in alcohol solutions, reduces the weight, and size of implanted Colon-25 tumors in Balb-c mice, (2) these same dosages of quercetin all produce a profound neutrophilia combined with a significant lymphopenia at day 20 post-implantation, and (3) there was relatively little evidence of histological changes in the quercetin-treated tumor section which would indicate that the action(s) of quercetin is primarily at the subcellular level probably within the nuclei of the tumor cells.

Date: May 2000
Creator: Gutierrez, Charletta Frances
Description: The widespread distribution of personal computers (PCs) throughout organizations has made a substantial impact on information systems. Additionally, the tremendous growth of the Internet has changed the way business is carried out. As the user population evolves into a much more technical and demanding group, their needs are also changing. With this change, Management Information Systems (MIS) departments must develop new ways of providing service and support to the user community. This study investigates the relationship between information systems support structures, support services, service quality and the characteristics of a diverse user population. This includes investigating technical support issues influencing user satisfaction. This study attempts to improve the understanding of the support function within MIS. The results of this study clarify the support needs of the users and identify user satisfaction factors, as well as factors relative to the quality of the support received. Six streams of prior research were reviewed when developing the research framework. These include: user support, end users and end-user computing, identifying and classifying user types, information centers, user satisfaction, service quality and other sources of computer support. A survey instrument was designed using the (UIS) user satisfaction instrument developed by Doll and Torkzadeh (1988) and ...

Decision Making Factors in Child Caregiver Reporting of Child Abuse and Neglect

Decision Making Factors in Child Caregiver Reporting of Child Abuse and Neglect

Date: May 2000
Creator: Hagen, Carol Kellerman
Description: This study investigated decision making factors used by child caregivers to identify suspected child abuse and neglect and collected data on caregiver training in the recognition and reporting of suspected child abuse and neglect. Data was collected in July 1999 in fourteen north Texas childcare programs. One hundred twenty three teaching and administrative staff completed a survey based on Jacobson, A., Glass, J. and Ruggiere, P. (1998). Five teachers and five administrators chosen for convenience were read eleven vignettes describing possibly abusive situations to decide whether they were reportable or non-reportable, and to indicate factors used to make their decisions. Administrators (50%) and teachers (13.3%) reported being unfamiliar with child abuse and neglect definitions and reporting laws. Two thirds (66.7%) of the administrators and 39.8% of the teachers had received specific training in recognizing and reporting child abuse and neglect. Administrators were more likely than teachers to report suspected child abuse and neglect. Teachers often reported to program administrators rather than state designated authorities. All subjects relied on information about children, but administrators also used information about parents, with teachers more likely to make excuses for parental actions. With 110 reporting opportunities, training was cited as a factor only twice ...
