A Comparison of a Computer-Administered Test and a Paper and Pencil Test Using Normally Achieving and Mathematically Disabled Young Children (open access)

A Comparison of a Computer-Administered Test and a Paper and Pencil Test Using Normally Achieving and Mathematically Disabled Young Children

This study investigated whether a computer-administered mathematics test can provide equivalent results for normal and mathematically disabled students while retaining similar psychometric characteristics of an equivalent paper and pencil version of the test. The overall purpose of the study was twofold. First, the viability of using computer administered assessment with elementary school children was examined. Second, by investigating items on the computer administered mathematics test for potential bias between normally achieving and mathematically disabled populations, it was possible to determine whether certain mathematical concepts consistently distinguish between the two ability groups.

A Weak-Form Efficient Markets Test of the Dallas-Fort Worth Office Properties Real Estate Market (open access)

A Weak-Form Efficient Markets Test of the Dallas-Fort Worth Office Properties Real Estate Market

Few areas of research in the finance literature have received greater attention than the efficient market hypothesis. Much of the research has been directed toward the securities market while very little research has been done in the real estate markets. The existing research on real estate market efficiency has been either descriptive or illustrative with very little empirical testing being performed. The major reason for the lack of empirical testing has been the inability to develop an adequate data base. The results of the empirical work that has been done do not support the widely held belief that real estate markets are inefficient. This study, using the autoregressive-integrative-moving average (ARIMA) time series analysis technique, tests the weak-form efficiency of the Dallas-Fort Worth office properties real estate market. According to the weak-form efficient market hypothesis, all price information should be capitalized into current real estate prices and not provide the basis for earning abnormal returns in trading. Price data formed from office building sales dating from January, 1979 to January, 1985 are used to test the market. The data was gathered from the files of several professional appraisal firms located in the Dallas-Fort Worth area. The transaction information includes (1) transaction …

Factors Related to Travel Mode Choices in the Dallas-Fort Worth Metropolitan Area (open access)

Factors Related to Travel Mode Choices in the Dallas-Fort Worth Metropolitan Area

This study examined the factors related to travel mode choices in the Dallas-Fort Worth Metropolitan Area. Changes in population, life style and economy of the Dallas-Fort Worth region over the last few decades demand a careful re-examination of travel demand tools and methods. The purpose of the study was to provide an understanding of transportation modal choice in the region. Those demographic variables best predicting the choices were identified. The Home Interview Survey, a set of disaggregate data from the 19 84 North Central Texas Council of Governments (NCTCOG) Regional Travel Survey, was analyzed using logistic regression. The major findings of the research indicate that about 97 percent of the travelers in the study area used private cars and 3 percent used public transit. Household income and cars-vans were significant explanatory variables. The impact of household income and number of car-vans available upon an individual's decision for travel mode choice were very important. The number of car-vans available in the household, and age of respondents were significant predictors in travel mode. Household members with incomes of $30,000 to $39,000 and those with incomes of at least $50,000 tended to use more private cars than did other income groups. Also, household …

The Use of Shared Service Arrangements by Member Hospitals of the Dallas Hospital Council (open access)

The Use of Shared Service Arrangements by Member Hospitals of the Dallas Hospital Council

This study was designed to assess the types of shared service arrangements and the degree of commitment as evidenced by the incorporation of policy statements displayed toward the sharing concept evident in the Dallas-Fort Worth hospitals. The purpose of this research, then, was to identify and evaluate present utilization of shared arrangements to establish a base for comparison and recommendations for future participation by the various categories of hospitals. The conclusions derived from the findings include the following: 1. Shared services promise to be a continuing factor in the operation of the health care industry in the future. 2. Governmental influence and regulation will expand into every area of health care. Hospital administrators must take every opportunity to contribute input to the formulation of these regulations. 3. The selection of products or services to be shared must be handled in a systematic manner complete with a control system to assure continued quality levels. 4. Standardization of product specifications is the single largest obstacle to the expansion of the shared service concept. This obstacle can be removed only through the committed involvement of the medical community. 5. The sharing of services, rather than products, appears to have great potential in terms …

Independent Piano Teachers: An Investigation of Their Attitudes toward Selected Attributes of Profession

The purpose of the study was to investigate independent piano teachers' view of themselves in the light of selected attributes found in sociological writings on the professions. The research problems were: (a) to determine the attitudes which independent piano teachers held toward selected professional attributes; (b) to determine the relationship between the attitudes toward the professional attributes and selected background variables; and (c) to determine the degree of association between these attributes. The problems were addressed by a questionnaire directed to independent piano teachers active in the area of Dallas-Ft. Worth, Texas. Thirty teachers were also interviewed to determine consistency of response and to explore issues which the questionnaire had raised. Reliability and validity were established at acceptable levels. Techniques of statistical analysis included Pearson's product-moment correlation, multiple regression, chi-square in conjunction with Cramer's V_, and factor analysis. The strongest attitudes expressed by the teachers in the study concerned professional self-image, altruism, client orientation, commitment to work, and independence. The most important background variables were age, years of experience, number of students, certification by a professional association, and college degree in music. A multiple regression analysis tested each variable against the dependent variable professional self-image; recognition by others, commitment to …

The Influence of Selected Factors on Nonpersistence of Nontraditional Students at a Comprehensive Community College

The purpose of the study was to determine the direct influences of selected environmental, academic, and background factors as well as academic outcomes and expression of intent to leave on persistence or non-persistence of nontraditional students at a comprehensive community college in the Dallas County Community College District. The study applied a conceptual model of nontraditional undergraduate student attrition. Data for this study were collected during the Fall, 1987 semester from 312 first-year nontraditional students using the two-year institution questionnaires from the National Center for Higher Education Management Systems. In addition, follow-up surveys were administered to the 97 students who did not re—enroll for the Spring, 1988 semester. The data were analyzed using discriminant function, chi square, and product-moment correlation. For these nontraditional students, educational goal commitment, cumulative grade point average (GPA) and expression of intent to leave at the end of the semester had significant direct influence on persistence or non-persistence decisions. In contrast, environmental factors such as finances, employment status, and family responsibilities, and background factors such as high school academic performance, enrollment status and parents' education level did not directly influence dropout decisions. Nontraditional students reported receiving moderate to high levels of encouragement to remain in college …

Characteristics and Predictors of Success at Two Coed Halfway Houses

The present study evaluated offender characteristics associated with completion of halfway house placement by the inclusion of additional offender characteristics for analysis in addition to those studied in previous research, the analysis of a large number of representative cases, and the use of statistics allowing clear conclusions upon which to base decision making. Data analysis was done in three steps. The first Step was to identify offender characteristics which were associated with completion in halfway house placement. The second step was to see how accurate the offender characteristics identified were in predicting completion of an offender's halfway house stay. The third step was to identify any possible factors which underlie the offender characteristics identified. Discriminant analyses identified ten offender characteristics which were associated with completion of halfway house placement for 521 male offenders and four offender characteristics which were associated with halfway house completion for the group of 33 female offenders studied. These offender characteristics resulted in 75.38 percent correctly classified cases for the male offender group and 96.9 7 percent correctly classified cases for the group of female offenders. Factor analyses resulted in the identification of four factors for the group of male offenders and two factors for the …

The Status of Preretirement Planning Programs in Dallas Corporations (open access)

The Status of Preretirement Planning Programs in Dallas Corporations

This investigation concerns the extent and nature of corporate preretirement planning programs in Dallas to ascertain employee access to retirement information and planning at the place of employment. Seven variables and their relationship to the existence of these programs are also studied. This study indicates that Dallas employees have limited access to retirement information through their employer. Existing programs often come too late for financial planning. Forty-nine of the 85 corporations have fewer than 1,000 employees, usually considered too few for a program. This study found that corporations with 5,000 or more employees may not have a program due to the nature of their business which necessitates dispersal of employees or requires younger employees with training in new technologies. The cost of a program was a deterrent for one corporation. Twelve respondents believe such programs are not the responsibility of business.

Organochlorine Pesticides and Heavy Metals in Fish From the Trinity River, Texas

The Trinity River passes through the Dallas-Fort Worth metroplex receiving point and non-point source contaminant loadings. Lepomis spp. were collected at twelve sampling locations in the Trinity River in August 1987 and September 1988 and analyzed for organochlorine pesticides and heavy metals. Results from the study were compared to existing U.S. FDA action and tolerance levels, LC50s, and historical data. Various longitudinal trends and some concentration patterns were observed. Continual study of pesticide and metal body burdens in fish allow testing for trends, and thereby, lead to a better understanding of the distribution of contaminants in the Trinity River.

A Study of the Public Relations Structures and Activities at Selected Dallas Hotels

The study was designed to identify the public relations structures at eight Dallas hotels, their functions and activities, and if public relations effectiveness is evaluated. Findings were based on sixteen interviews with senior management and public relations coordinators. The study concluded that public relations programs are structured by either separate public relations department, public relations activities combined with other department, or an external agency. The public relations functions range from image-building to participation in sales and marketing with primary responsibility of promotion and publicity dominated by economic considerations. One weakness is the lack of formal research methods to discern public opinion. There is a lack of understanding by hotel management of the potential and scope of public relations programs.

Sediment Bound Trace Metals in the White Rock Creek Watershed, Dallas and Collin Counties

Areas were sampled in the White Rock Creek Watershed to examine sediment bound trace metal distributions and sorption relationships. A Kruskal-Wallis AOV found significant among area differences for most metals, and SNK-like multiple comparisons were used to group these areas. Kruskal-Wallis AOVs similarly found among area differences for sediment components that bind trace metals (Fe and Mn oxides and organic carbon) and physicochemical conditions that influence metal sorption (particle size and pH). Multiple correlation found numerous relationships among trace metals, sediment components, and physicochemical conditions. Statistical relationships indicate that metal partitioning to various sorption factors is metal specific. White Rock Creek Watershed trace metal concentrations are comparable to those in many urban watersheds.

The Landscape Legacies of Gas Drilling in North Texas (open access)

The Landscape Legacies of Gas Drilling in North Texas

In North Texas, the Barnett Shale underlies large areas of the Dallas-Fort Worth Metroplex (DFW), which magnifies debates about the externalities of shale gas development (SGD). Continued demand for natural gas and expansive urbanization in DFW will cause more people to come in contact with drilling rigs, gas transport, and other urban shale gas landscapes. Thousands of gas wells within the DFW region occupy a large, yet scattered land surface area. DFW city planners, elected officials, and other stakeholders must deal with current and future urban growth and the surface impacts that are associated with gas development. This research examines how shale gas landscapes affect urban land uses, landscapes, and patterns of development in DFW. The study focuses on multiple fast growing DFW municipalities that also have high numbers of gas well pad sites. This study asks what are the spatial characteristics of gas well production sites in DFW and how do these sites vary across the region; how do gas well production sites affect urban growth and development; and how are city governments and surface developers responding to gas well production sites, and what are the dominant themes of contestation arising around gas well production sites and suburban growth?

Evaluating the Efficacy of Engagement Journalism in Local News: An Ethnographic Study of the Dallas Morning News

The Dallas Morning News is a leader in using engagement journalism to increase and retain digital subscribers. This ethnography examined the efficacy of the engagement journalism work by the News in rebuilding trust and forming relationships with its audience. This research is exceptionally timely as more newsrooms are erecting paywalls to their content and asking their audiences to offer monetary support in exchange for greater access and engagement by journalists. This work is examined through two mass communications theories: functionalism, which says a society can be viewed like an ecosystem as a "system in balance" consisting of complex sets of interrelated activities, each of which supports the others in maintaining the system as a whole; and the dual responsibility model, which says that companies should operate in the best interests of all in the community who depend on them, not only those who benefit financially. Additionally, the work is considered from a human-interaction design standpoint to evaluate whether the News has created affordances that enable the journalists and the readers to communicate, and whether the journalists are effectively practicing service design when publishing news and information for the audience.

Teacher Implementation of a Pretreatment Assessment Procedure in a Public Middle School (open access)

Teacher Implementation of a Pretreatment Assessment Procedure in a Public Middle School

In an attempt to determine the effectiveness of a pretreatment assessment procedure known as the scatter plot (Touchette, MacDonald, & Langer, 1985), direct observational data was collected by 13 middle school teachers on four "problem" students. After four weeks of data collection, interobserver agreement probes were calculated and a visual analysis of the plotted data was performed to ascertain a possible pattern of problem behavior. Additionally, in an attempt to assess the teachers' perceptions of the scatter plot, the 13 teachers were asked to complete a questionnaire. Although a visual analysis of the plotted data suggested a possible pattern of problem behavior, interobserver agreement probes failed to achieve a desired overall reliability of 90% or higher. Despite a low IOA, results of the questionnaire administered to the 13 teachers generally supported the use of the scatter plot as a means of assessing student behavior. Possible reasons for failing to attain an IOA of 90% or higher include the total number of students in a class, the number of subjects observed per period, the teacher's location in the classroom, and the subjects ability to recognize if the teacher was "looking." Recommendations are provided regarding future research concerning the scatter plot and …
