A Delphi Study to Determine if SCANS Workplace Know-How Can Be Developed through the Achievement of National Standards for [Visual] Arts Education

Description: The purpose of this study was to provide a basis for understanding among Tech Prep and School-to-Work change agents, and educational leaders, of the role that Discipline-Based Art Education (DBAE) can perform as a part of the core curriculum, within the framework of these reform movements. The literature indicated that the federally supported Tech Prep and School-to-Work reform movements were not acquainted with DBAE reform initiative which were supported by the Getty Education Institute for the Arts through the work of Regional Institutes. Therefore, they had no ideas about the possible worth of art as an education core component. Also, DBAE was not acquainted with Tech Prep and School-to-Work and therefore had established no common terminology to communicate the power of what they do in a manner which was relevant to that audience. The DBAE Regional Institutes provided individuals to assist in the development and validation of the study tools, and to participate in the pilot study. The Regional Institutes also identified the 10 Discipline-Based Art Education experts who composed the national Delphi panel for the study. The findings were reported according to research questions. They show the national Delphi panels' perceptions of which SCANS skills can be developed by Content Standards and Performance Standards from the National Standards for [Visual] Arts Education. The study concluded that: 1) there is a relationship between the Content and Performance Standards taken from the National Standards for [Visual] Arts Education and the SCANS skills; 2) SCANS Basic skills, Thinking skills, Resources skills, Information skills and Systems skills could be developed through the achievement of the Performance Standards of the National Standards for [Visual] Arts Education; and 3) the relationship between the SCANS Workplace Know-How skills and the National Standards for [Visual] Art Education was validated by a national Delphi panel. Recommendations were made ...

The Distribution of Environmental Contaminants: a Socio-Historical Study of Selected Neighborhoods in Dallas County, Texas

Description: This research expands on recent sociological studies which maintain that environmental contaminants in America are disproportionately placed in neighborhoods inhabited by minorities and the poor. Prior studies have focused on the predictor variables which identify areas of contamination near residential neighborhoods, yet fail to explore the socio-political and historical factors which contribute to these phenomena. The Environmental Protection Agency's Toxic Release Inventory 1990 database, the Texas Natural Resource Conservation Commission's Annual Report of the Hazardous and Solid Waste Program for 1992, and the U.S. Census Bureau's 1990 Census Data for Dallas County were utilized in pinpointing industries violating toxic release standards. Socio-historical data was obtained from government and historical records and reports, books, and newspaper clippings on Dallas County. Maps and data were obtained from the North Central Texas Council of Governments, and the cities of Dallas and Garland. Chapter I discusses the synergetic forces of capitalism, urban growth, uneven development, and settlement patterns resulting in the distribution of environmental contaminants. Chapter II reviews the literature and presents evidence that race and class are strong predictors of where environmental contaminants are located. Chapter III outlines the data and methods employed. Chapter IV traces the historical development of Dallas County. Chapter V details those political, economic, and social factors contributing to the convergence of people and contaminants within three selected neighborhoods. The forces which historically relegate minorities, particularly Blacks and Hispanics, and the poor to less desirable jobs, cheaper housing, and land costs are also explored. Cheap land and labor attract industry which, in turn, attracts more laborers. Chapter VI, the summary and conclusions, utilizes the socio-spatial approach in examining urban infrastructure development (i.e. roads and railways) which also reduces adjacent land costs making housing more affordable for minorities and the poor. This study concludes that because of historical development and ...

Evaluation of Text-Based and Image-Based Representations for Moving Image Documents

Description: Document representation is a fundamental concept in information retrieval (IR), and has been relied upon in textual IR systems since the advent of library catalogs. The reliance upon text-based representations of stored information has been perpetuated in conventional systems for the retrieval of moving images as well. Although newer systems have added image-based representations of moving image documents as aids to retrieval, there has been little research examining how humans interpret these different types of representations. Such basic research has the potential to inform IR system designers about how best to aid users of their systems in retrieving moving images. One key requirement for the effective use of document representations in either textual or image form is thedegree to which these representations are congruent with the original documents. A measure of congruence is the degree to which human responses to representations are similar to responses produced by the document being represented. The aim of this study was to develop a model for the representation of moving images based upon human judgements of representativeness. The study measured the degree of congruence between moving image documents and their representations, both text and image based, in a non-retrieval environment with and without task constraints. Multidimensional scaling (MDS) was used to examine the dimensional dispersions of human judgements for the full moving images and their representations.

Virtual Reality for Scientific Visualization: an Exploratory Analysis of Presentation Methods

Description: Humans are very effective at evaluating information visually. Scientific visualization is concerned with the process of presenting complex data in visual form to exploit this capability. A large array of tools is currently available for visual presentation. This research attempts to evaluate the effectiveness of three different presentation models that could be used for scientific visualization. The presentation models studied were, two-dimensional perspective rendering, field sequential stereoscopic three dimensional rendering and immersive virtual reality rendering. A large section of a three dimensional sub surface seismic survey was modeled as four-dimensional data by including a value for seismic reflectivity at each point in the survey. An artificial structure was randomly inserted into this data model and subjects were asked to locate and identify the structures. A group of seventeen volunteers from the University of Houston student body served as subjects for the study. Detection time, discrimination time and discrimination accuracy were recorded. The results showed large inter subject variation in presentation model preference. In addition the data suggest a possible gender effect. Female subjects had better overall performance on the task as well as better task acquisition.

Remote Sensing of Landscape-Level Ecological Attributes at Ray Roberts Lake in North Texas

Description: Biological diversity is a key component in assessing ecosystem health. Alteration, degradation and loss of habitat due to human influence is currently the primary stressor resulting in decreases in diversity. Reliable assessment of large areas in terms of biological integrity are needed for conservation and preservation efforts. Remotely sensed data provide an integrated view of reflected electromagnetic energy over large areas of the earth. These energy patterns provide unique spectral signatures which can be correlated to land cover and habitat. This research sought relationships between traditional ecological measures and information gathered from satellite digital imagery. Reliable interpretation of earth surface characteristics relies largely on accurate rectification to a map projection and subsequent thematic classification. Use of the Global Positioning System (GPS) for rectification was superior than digitizing topographical maps. Differentially corrected GPS locations provided optimum rectification with SPOT satellite imagery while marginally better rectifications were obtained for Landsat MSS imagery using uncorrected GPS positions. SPOT imagery provided more accurate land cover classifications than did MSS. Detection of temporal land cover change using MSS imagery was hampered by confusion among intermediate successional classes. Confusion between upland and bottomland forest classes occurred with both SPOT and MSS. Landscape analyses using thematic maps produced from the previously discussed endeavors suggested that terrestrial habitat in the Ray Roberts Lake area became more fragmented and complex in shape. Habitat patches became smaller but more numerous. Forested areas were most effected and conservation efforts should focus on management strategies that promote vegetation succession and forest maturation. Remotely sensed SPOT data were successfully used to predict tree basal area. There were no significant relationships found with other in situ measures or between MSS data and any vegetation measures. Remote sensing provided information suitable for large scale projects concerning landscape-level ecological issues. Rectification and classification accuracies were the ...

Into the Woods: Wilderness Imagery as Representation of Spiritual and Emotional Transition in Medieval Literature

Description: Wilderness landscape, a setting common in Romantic literature and painting, is generally overlooked in the art of the Middle Ages. While the medieval garden and the city are well mapped, the medieval wilderness remains relatively trackless. Yet the use of setting to represent interior experience may be traced back to the Neo-Platonic use of space and movement to define spiritual development. Separating themselves as far as possible from the material world, such writers as Origen and Plotinus avoided use of representational detail in their spatial models; however, both the visual artists and the authors who adopted the Neo-Platonic paradigm, elaborated their emotional spaces with the details of the classical locus amoenus and of the exegetical desert, while retaining the philosophical concern with spiritual transition. Analysis of wilderness as an image for spiritual and emotional transition in medieval literature and art relates the texts to an iconographic tradition which, along with motifs of city and garden, provides a spatial representation of interior progress, as the medieval dialectic process provides a paradigm for intellectual resolution. Such an analysis relates the motif to the core of medieval intellectual experience, and further suggests significant connections between medieval and modern narratives in regard to the representation of interior experience. The Divine Comedy and related Continental texts employ both classical and exegetical sources in the representation of psychological transition and spiritual conversion. Similar techniques are also apparent in English texts such as Beowulf and the Anglo-Saxon elegies, in Geoffrey Chaucer's The Book of the Duchess, The House of Fame, and Troilus and Criseyde, and in the northern English The Pearl and Sir Gawain and the Green Knight. These literary texts, further, include both ideas and techniques which are analogous to those of visual arts, where frescos and altarpieces show the wilderness as metaphor for transition, and ...

Assessing the Psychological Impact of Fertility Treatment

Description: This controlled descriptive study was designed to investigate the psychological status of couples who are engaged in advanced fertility treatments. A battery of psychological test instruments, including the Millon Behavioral Health Inventory (MBHI), the Health Attribution Test (HAT), the Beck Depression Inventory (BDI), the Beck Anxiety Inventory (BAI), and the Marlowe-Crowne Social Desirability Scale (MCSDS), was used to measure psychological variables that have been shown in the infertility research literature to be associated with the psychological experiences of infertility patients. The scores from the four assessment instruments were compared with those of pregnant couples in childbirth education classes to differentiate the impact of stress associated with fertility treatment from the stress experienced by third trimester pregnant couples. Eighty-five subjects (42 male and 43 female) volunteered for the study and completed packets of questionnaires. The groups were designated Treatment (infertile couples) and Control (pregnant couples). The resulting data were collected and analyzed on the basis of group mean scores on the test instruments.

Prediction of Aggressive and Socially Disruptive Behavior among Forensic Patients: a Validation of the Psychopathy Checklist Screening Version

Description: Psychopathic criminals commit more crimes, are more prone to recidivism, and more likely to engage in violent crimes and other aggressive behavior than nonpsychopathic criminals. Less is known about forensic patients, both with and without psychopathy, and their aggression. In the current study, patients in a maximum security hospital were examined with respect to their psychopathy and its predictive value on institutional management and dangerousness. In this regard, the Psychopathy Checklist (PCL) and the Psychopathy Checklist - Revised (PCL-R) have proven to be valid and reliable measures of psychopathy. The present study was an attempt to establish predictive validity for a new version: the Psychopathy Checklist Screening Version (PCLSV). As such, this study examined the PCL-SV's relationship to (a) diagnoses of Antisocial Personality Disorder according to DSM-III-R criteria and (b) the Personality Assessment Inventory (PAI) Aggression, Drug Problems, and Antisocial Features scales. The influence of major Axis I disorders on the assessment of psychopathy with the PCLSV was also examined. Participants were 150 male forensic psychiatric patients at Vernon State Hospital who were committed for various reasons: incompetence to stand trial, initial evaluation and treatment after having been found not guilty by reason of insanity, and manifest dangerousness. Chart reviews were completed for a six month follow-up period during which all instances of aggressive or socially disruptive behaviors were recorded. Results supported the predictive validity of the PCL-SV as a measure of psychopathy for aggression and treatment noncompliance. Unexpected findings among correlations of the PCL-SV with the PAI Antisocial Features scale were examined and discussed. A review of the costs and benefits of the PCL-SV in clinical decision making is presented and the clinical utility of the present findings is discussed.

An Analysis of the Impact of Curriculum Management Audits on Public School Systems in Texas

Description: The purposes of this study were to (1) identify the recommendations of Curriculum Management Audits conducted in Texas Public School systems, (2) determine the degree to which each of the recommendations had been implemented, and (3) determine the perceptions of stakeholders as to the factors instrumental in the real and potential impact of the audit. The researcher conducted interviews with superintendents and key central office administrators with a working knowledge of the audit report in each of the eleven Texas school districts studied. Respondents were asked to rate recommendations written for their districts using the following descriptors: Implemented, In Progress, Plan to Implement, Recommendation Modified, No Implementation. The ranking of recommendation implementation revealed that 85% of the recommendations made in the 11 audit reports reviewed in this study had received action toward implementation to some degree. Respondents were also asked to cite factors which facilitated or impeded recommendation implementation. Significant factors facilitating the implementation of recommendations were reported to be time, organizational structure/personnel and planning. The analysis of the collective recommendations revealed that school board policies were not adequate to direct the design, delivery and monitoring of curriculum when measured against audit Standard One criteria. School districts in Texas rely on the Texas Association of School Boards' policy division for policies. Findings indicate that greater alignment between the Texas Association of School Boards' policies and Curriculum Management Audit criteria must be sought in order for school districts in Texas to meet this Standard. System-wide planning, curriculum documents, and program-driven budgeting processes were other areas requiring attention of the school districts in the study. Evidence of the extent of implementation of recommendations suggests that school districts valued the audit report with its recommendations. It can be generally concluded that the Curriculum Management Audit had a positive impact on the involved school ...

Texas Public School Library Media Specialists' Perceptions of the Use of the Internet in their Schools

Description: With the advent of the 21st century, technological innovations are transforming the face of education and the school library media center. One of these significant developments is the ability to communicate through the Internet. The purpose of this study is to examine the perceptions of Texas public school library media specialists who are active Internet users about their utilization of the Internet, and how their efforts in implementing and supervising Internet access in their school library media centers impact the Texas public schools that they serve. A survey instrument of Likert items was developed that queried these public school library media specialists for their perceptions of Internet use in their schools. MANOVA was the chosen statistical measure for this study. An initial electronic mail-out to 1,232 Texas public school library media specialists (K-12) with Internet addresses were contacted to participate in this study. After a time frame of one month, 196 Texas school library media specialists e-mailed the researcher, confirming their willingness to be a survey participant. All respondents to this e-mail request participated in this study, and a second U.S. mail-out was sent containing the actual survey instrument. The researcher found that the use of the Internet by school library media specialists in Texas did not increase global collegiality from the viewpoint of the survey respondents. Survey respondents felt that an Internet acceptable use policy did not ensure student access to the Internet in Texas public school library media centers. The study examined the relationship between acceptable use policies and Internet censorship, and the researcher found no connection between these two elements from the perspective of the school library media specialist. The study found that school library media specialists believe that their training did improve their students' library research skills. Furthermore, the survey respondents believed that their Internet training ...

An Examination of the Effect of Decision Style on the Use of a Computerized Project Management Tool

Description: Managing a software development project presents many difficulties. Most software development projects are considered less than successful, and many are simply canceled. Ineffective project management has been cited as a major factor contributing to these failures. Project management tools can greatly assist managers in tracking and controlling their projects. However, project management tools are very structured and analytical in nature, which is not necessarily supported by decision-making styles of the managers. This research examined the influence that decision style has on a project manager's use of a project management tool.

Hebrew Wisdom as the Sitz im Leben for Higher Education in Ancient Israel

Description: This research grows out of an interest in what scholars commonly call the wisdom tradition of the ancient near east. This tradition or movement involved groups of thinkers and writers, known collectively as scribes, who were concerned in a philosophical way with the problems of living, and with principles of living well. Such communities are known to have flourished in Egypt, the various kingdoms of Mesopotamia, and western Asia, from at least the middle of the third millennium B.C. These scribal communities are also known to have sponsored schools, intended primarily for training in statecraft and the professions, but also for training in the scribal profession per se. The documentary and historical record indicates that such schools provided education from the most rudimentary level of literacy and writing to the most advanced levels of scribal scholarship. These advanced levels of training were functionally equivalent to what is nowadays known as higher education; and the ideals, the philosophy, which guided this enterprise found expression in a corpus of literature bearing the name "wisdom." The problem for this dissertation is whether or not there was in ancient Israel, specifically in the Solomonic era (10th century, B.C.), such an advanced scribal school associated with a Hebrew wisdom tradition. This is a research problem precisely because the evidence for such a school in Israel is both less abundant and less accessible than for the rest of the ancient near east.

Sulfur-induced Corrosion at Metal and Oxide Surfaces and Interfaces

Description: Sulfur adsorbed on metallic and oxide surfaces, whether originating from gaseous environments or segregating as an impurity to metallic interfaces, is linked to the deterioration of alloy performance. This research dealt with investigations on the interactions between sulfur and iron or iron alloy metallic and oxide surfaces under ultrahigh vacuum conditions. Sulfur was either intentionally dosed from a H2S source on an atomically clean metal surface, or segregated out as an impurity from the bulk to the metal surface by annealing at elevated temperatures.

Earnings Management and the Independence or Interdependence of Accounting Choices: the Decision to Adopt Mandated Accounting Changes

Description: This research examines whether firms managed earnings in the year they adopted SFAS 109, Accounting for Income Taxes (or its predecessor SFAS 96), by combining the choice to adopt SFAS 109 with other accounting choices in an interdependent rather than independent manner. Prior literature generally analyzes only one specific accounting choice, assuming that the decision is independent of other accounting procedure choices. However, it is unlikely that managers act in this manner. When attempting to achieve certain income goals, managers have numerous accounting tools available to them including the choice of accounting procedures and the exercise of judgment as to accrual amounts. This study investigates five choices consisting of: (1) the adoption of SFAS 109/96; (2) the adoption of SFAS 106; (3) the reporting of a restructuring of operations and/or a write-down of assets; (4) the reporting of asset sales; and (5) the choice of discretionary accruals. The study adopts both a portfolio and joint decision approach. The portfolio approach combines the earnings effects of the five choices into a single dependent variable and tests income smoothing, big bath, and debt hypotheses. The joint decision approach utilizes simultaneous equation methodology to investigate the interdependence of the five choices and the independent variables. The portfolio approach findings provide evidence that firms used the combined effect of the five accounting choices to smooth income in the year they adopted FAS 109/96. The results also provide support for the debt hypothesis but do not support the big bath hypothesis. The joint decision approach findings provide evidence that firms jointly determined at least two of the five accounting choices. The strong support for the income smoothing hypothesis under the portfolio approach combined with the joint significance of the individual accounting choices in the simultaneous equations suggests that firms use a multitude of accounting choices ...
