Ethics of Teaching: Beliefs and Behaviors of Community College Faculty (open access)

Ethics of Teaching: Beliefs and Behaviors of Community College Faculty

This study examines the ethical beliefs and behaviors of full-time community college faculty. Respondents report to what degree they practice sixty-two behaviors as teachers and whether they believe the behaviors to be ethical. Survey participants engaged in few of the behaviors, and only reported two actions as ethical: (1) accepting inexpensive gifts from students and (2) teaching values or ethics. The participants reported diverse responses to questions about behavior of a sexual nature, but most agreed that sexual relationships with students or colleagues at the same, higher or lower rank were unethical. Additional findings relate to the presence of diversity among the faculty, using school resources to publish textbooks and external publications, selling goods to students, and an expansive list of other behaviors. Findings of this study are compared to results from earlier studies that utilized the same or similar survey instrument with teaching faculty. The study has implications for organizational policy and procedure, for faculty training and development, the teaching of ethics or values in the classroom and for future research.

Anything Like Us (open access)

Anything Like Us

Anything Like Us is a collection of poems with a critical introduction. In this introduction, I explore modern alternatives to Romantic and Neo-Romantic lyric expression. I conclude that a contemporary lyric that desires to be, in some fashion, about itself, must exhibit an acceptance of the mediating influences of time and language, while cultivating an inter-subjective point-of-view that does not insist too much on the authority of a single, coherent voice. The poems in Anything Like Us reflect, in both form and content, many of the conclusions advanced in the introduction. Nearly all the poems concern the desire for, and failure to find, meaningful connections in an uncertain world .

Sexual orientation self-label, behavior, and preference: College students in Taiwan and the USA (open access)

Sexual orientation self-label, behavior, and preference: College students in Taiwan and the USA

The relationships among self-labeled sexual orientation, sexual preferences, and sexual behaviors were examined in samples from Taiwan and the USA. Subsamples matched on gender, age, and marital status were created to reduce sexual orientation cell size discrepancies and demographic differences. Sexual orientation self-label, the Kinsey Scale of Sexual Orientation, and a modified version for preference were used to assess participants' sexual orientation, behavior, and preference, respectively. Additional measures included an adaptation of the Early Sexual Experiences Checklist, and the Hopkins Symptom Checklist for psychological distress. For both Taiwan and USA subsamples, heterosexual participants reported significantly greater congruence between sexual orientation identity and preference than did nonheterosexual participants. A high proportion of the Taiwan sample were celibate, precluding analyses of congruence between sexual orientation identity and sexual behavior. Congruence between sexual behavior and preference in the USA sample was negatively correlated with psychological distress. In a cross-cultural comparison between the Taiwan and USA women (n = 176), the two samples reported similar congruence between sexual orientation identity and preference. Exploratory analyses revealed that heterosexual participants' sexual orientation label was more “public, ” (more categories of people who knew the participants' sexual orientation), than was nonheterosexuals' in both Taiwan and the USA. …

A Comparison of Mall Shopping Behavior Between Hispanic-Americans and Anglo-Americans (open access)

A Comparison of Mall Shopping Behavior Between Hispanic-Americans and Anglo-Americans

The population percentage, population growth, buying power, and geographic concentration of Hispanic-Americans in the United States is causing marketers and retailers to carefully examine this market segment. Through a better understanding of Hispanic-American consumers, marketers and retailers will be more capable of meeting their wants and needs. Tailoring marketing promotions and strategies can help a company more effectively reach the Hispanic-American market. This study compared Hispanic-Americans and Anglo-Americans in their general shopping characteristics, responses to excitement in the mall, consumption patterns, and repatronage intention. A total of seven hypotheses were developed, all of which were either supported or partially supported.

Use of geographic information systems and infrared-triggered cameras to assess white-tailed deer (Odocoileus virginianus) habitat in Denton County, Texas. (open access)

Use of geographic information systems and infrared-triggered cameras to assess white-tailed deer (Odocoileus virginianus) habitat in Denton County, Texas.

This study utilized geographic information systems, remote sensing, and infrared-triggered cameras to assess white-tailed deer habitat in Denton County, Texas. Denton County is experiencing tremendous growth in both population and development. Despite their presence here historically, white-tailed deer were all but extirpated by the beginning of the 20th century, and there are no data available which support their presence in Denton County again until the 1980's. This study attempts to equate the increase in white-tailed deer population to Denton County's transformation from an agricultural to an urban economy and lifestyle. Eighteen sites were chosen throughout the county to research the following metrics: geology, soils, landcover, landscape ecology, streams, shorelines, land use, population, roads, structures, and census methods.

A study of stock price reactions to the decisions of the Federal Open Market Committee (FOMC) on changes in the federal funds rate. (open access)

A study of stock price reactions to the decisions of the Federal Open Market Committee (FOMC) on changes in the federal funds rate.

This paper analyzes stock index reactions to interest rate actions by the FOMC. Unlike previous analyses this study utilizes macro-economic indicators and accounts for pre-decision market expectations. Results indicate significant reaction of the stock market to the actions of the FOMC regardless of interest rate actions matching pre-decision market expectations. Binary dummy variables representing the five days following an FOMC meeting indicate a significant reaction for days one; two and three of the Dow Jones model and for day five of the NASDAQ model. The magnitude of the coefficients are 0.17%, 0.09%, -0.07% and -.15% respectively. These findings may be sensitive to a priori choices regarding the definition of the market expectation variable.

Improving the Definition of Exercise Maintenance: Evaluation of Concepts Related to Adherence (open access)

Improving the Definition of Exercise Maintenance: Evaluation of Concepts Related to Adherence

Physical activity has been demonstrated in the literature as an effective way to reduce the risk for development of chronic disease. The Transtheoretical Model (TTM) of behavior change has been developed as a means to predict and facilitate movement into healthier lifestyle behaviors. The model is centered on "stages of change", which describe a continuum of readiness to engage in a health behavior change. Stages contain temporal, qualitative, and quantitative characteristics. This was a six-month study that evaluated the effectiveness of stage-matched (theorized to be pertaining only to the maintenance stage of change) vs. generic (theorized to be pertaining to anyone, regardless of stage) newsletters in assisting subjects to attain the Maintenance stage of change. It also sought to identify further qualitative characteristics that can differentiate between the Action and Maintenance stages of change. Results indicated that monthly stage-matched newsletters were no more effective in helping subjects reaching Maintenance than were the generic newsletters. Exerciser self-schema was related to stages of change, but those relationships differed from baseline to six-month follow-up, indicating development of exerciser self-schema during the study period. Implications of this are discussed. Other concepts discussed included "structure" of change process, in that three new scores were developed …

Leadership Frames of Female Presidents of American Research Universities (open access)

Leadership Frames of Female Presidents of American Research Universities

This study used case studies to examine the leadership frames of female presidents of four-year, public and private, coeducational research institutions both from the Intensive and Extensive Carnegie classifications within the United States. The population (N=30) surveyed was sent the Leadership Orientation Questionnaire (Self) developed from the previous research conducted by Lee Bolman and Terrance Deal. The Bolman and Deal leadership frame theory condensed existing organizational theories into a four-frame perspective consisting of a structural, human resource, political, and symbolic frame. Bolman and Deal theorized that the ability to use more than one frame is considered to be critical to the success of leaders and intensify that leader's capacity for making decisions and taking effective actions. The Leadership Orientation Questionnaire (Self) contains five sections that include rating scales for personal demographics, the four frames, eight leadership dimensions, and management and leadership effectiveness. The research questions sought to identify the demographic characteristics and academic histories of the survey participants and the associations between these variables, the leadership frames represented among the survey participants, and how many, and which, of the four frames the survey participants use collectively. This study allowed its participants to examine their perceptions of their own leadership frames …

Mechanisms of rapid receptive field reorganization in rat spinal cord (open access)

Mechanisms of rapid receptive field reorganization in rat spinal cord

Rapid receptive field (RF) reorganization of somatosensory neurons in the rat dorsal horn was examined using extracellular single unit recording. Subcutaneous injection of lidocaine into RFs of dorsal horn neurons results in expansion of their RFs within minutes. The expanded RFs appear adjacent to or/and proximal to original RFs. Out of 63 neurons tested, 36 (58%) show RF reorganization. The data suggest that dorsal horn of spinal cord is one of the initial sites for RF reorganization. The neural mechanisms of this effect are not well understood. We propose that changes in biophysical properties (membrane conductance, length constant) of the neurons resulting from lidocaine injection contribute to RF reorganization. Iontophoretic application of glutamate onto dorsal horn neurons that show lidocaine induced RF's expansion were used to test the model. Application of glutamate produced reduction of reorganized RFs in 9 of 20 (45%) tested cells. Application of NBQX produced no effect on either original or expanded RFs indicate that RF shrinkage effects of glutamate involve NMDA receptors. The results are consistent with the prediction of the proposed model. Subcutaneous injection of capsaicin into tactile RFs of low threshold mechanoreceptive dorsal horn neurons produced no effect on the RF sizes that are …

Influence of design and coatings on the mechanical reliability of semiconductor wafers. (open access)

Influence of design and coatings on the mechanical reliability of semiconductor wafers.

We investigate some of the mechanical design factors of wafers and the effect on strength. Thin, solid, pre-stressed films are proposed as a means to improve the bulk mechanical properties of a wafer. Three-point bending was used to evaluate the laser scribe density and chemical processing effect on wafer strength. Drop and strike tests were employed to investigate the edge bevel profile effect on the mechanical properties of the wafer. To characterize the effect of thin films on strength, one-micron ceramic films were deposited on wafers using PECVD. Coated samples were prepared by cleaving and were tested using four-point bending. Film adhesion was characterized by notched four-point bending. RBS and FTIR were used to obtain film chemistry, and nanoindentation was used to investigate thin film mechanical properties. A stress measurement gauge characterized residual film stress. Mechanical properties of the wafers correlated to the residual stress in the film.

Neuronal Network Analyses in vitro of Acute Individual and Combined Responses to Fluoxetine and Ethanol (open access)

Neuronal Network Analyses in vitro of Acute Individual and Combined Responses to Fluoxetine and Ethanol

Embryonic murine neuronal networks cultured on microelectrode arrays were used to quantify acute electrophysiological effects of fluoxetine and ethanol. Spontaneously active frontal cortex cultures showed highly repeatable, dose-dependent sensitivities to both compounds. Cultures began to respond to fluoxetine at 3 µM and were shut off at 10-16 µM. EC50s mean ± S.D. for spike and burst rates were 4.1 ± 1.5 µM and 4.5 ± 1.1 µM (n=14). The fluoxetine inhibition was reversible and without effect on action potential wave shapes. Ethanol showed initial inhibition at 20 mM, with spike and burst rate EC50s at 52.0 ± 17.4 mM and 56.0 ± 17.0 mM (n=15). Ethanol concentrations above 100 -140 mM led to cessation of activity. Although ethanol did not change the shape and amplitude of action potentials, unit specific effects were found. The combined application of ethanol and fluoxetine was additive. Ethanol did not potentiate the effect of fluoxetine.

The Regulation of Medically Assisted Procreation in Europe and Related Nations and the Influence of National Identity, Social Cultural, and Demographic Differences (open access)

The Regulation of Medically Assisted Procreation in Europe and Related Nations and the Influence of National Identity, Social Cultural, and Demographic Differences

This study details the Medically Assisted Procreation regulations in thirty-five nation-states, and explores the influence of national identity, social cultural and demographic differences on these regulations. Detailed data were gathered from ministries of health, offices of prime ministers, embassy staff, and others on regulations for each nation. These data were used to categorize the nations in regard to MAP legislation status and regulatory policy regarding marital or age restrictions; posthumous conception; sperm, ovum, or embryo donation, surrogacy; and policy on handling donors. Possible associations between national identity, social cultural, and demographic data for each nation and their regulations were explained. The thirty-five nations were treated as a population with common geographical and political ties. PRE methods, and eta coefficients were used to assess the associations. Sixteen nations have adopted MAP legislation, eight nations have either alternative regulatory guidelines or partial structures, four nations have legislation pending and possibly some laws, and seven nations are unregulated. Based upon statistical analysis, language group emerges as an important indicator for differences in MAP regulations. For example knowing a nation's language group enabled percent improved prediction of that nation's regulatory handling of embryo donation. The percent GDP spent on health care was found to …

Sequence without Uniformity (open access)

Sequence without Uniformity

The inspiration for my undergraduate body of work is derived from my fascination with Henri Matisse, Jacob Lawrence, and the Impressionists. I suddenly became captivated with the Impressionist movement and the independence of abstraction. I set into motion a series of paintings and drawings featuring random African-Americans and African society representatives in vibrant color and abstracting forms, and was specifically concerned with altering the form outside of the realistic area. While in graduate school, I began to think about how the transformation from realism to abstraction combined with the conception of mortal to the immortal. I worked through ideas to see exactly where these views began, and where they would take me as an artist. Almost immediately I experimented with random figures found specifically in the N'debele culture in South Africa. In addition, I incorporated abstraction and expressive marks within the figure and slowly introduced cut paper, flat imagery and abstraction with the realistic figure. This became very challenging but I was determined to unite these ideas successfully. More recently, my work has concentrated on the essential elements that have influenced my work as an artist, which recedes to childhood. The main elements most prevalent within the work is rhythm …

Religiosity as a moderator of anger in the expression of violence by women (open access)

Religiosity as a moderator of anger in the expression of violence by women

The purpose of this study was to determine the effects of women's anger and religiosity on their expression of violence toward their partner. The sample consisted of the 664 women who completed three interviews for Project HOW: Health Outcomes of Women, a study of low-income, ethnically diverse women in Dallas county. Across the waves, women completed measures of relationship violence, anger, and religiosity. Religiosity was not found to moderate the relationship between women's anger and their use of violence. When partners' threats and violence were included in the regression equations, these variables were consistently related to women's behavior. Due to several methodological limitations, clinical implications of the results should be considered with caution.

Breaking Through: A Composition for Symphony Orchestra

Access: Use of this item is restricted to the UNT Community
Breaking Through is a single-movement composition for symphony orchestra based on a fourteen-note melody. Every harmonic and melodic figure except the bass line is derived from this source melody. The structure of the work is based on a number of musical dichotomies that work on both local and large-scale levels. The local dichotomies contrast consonance with dissonance and ambiguity with clarity (in respect to texture and rhythm). The dichotomy of two-part form versus three-part form and the dichotomy of simplicity versus complexity operate on the large scale. The unity lended by the single source melody coupled with the contrasts furnished by the aforementioned dichotomies allow Breaking Through to be both coherent and interesting.

Changing Privacy Concerns in the Internet Era.

Access: Use of this item is restricted to the UNT Community
Privacy has always been a respected value regardless of national borders, cultural differences, and time in every society throughout history. This study focuses on the unprecedented changes in the traditional forms of privacy and consequent concerns with regard to invasion of privacy along with the recent emergence and wide use of the Internet. Government intrusion into private domains through the Internet is examined as a major concern. Privacy invasions by Web marketers, hacker threats against privacy, and employer invasion of employee privacy at the workplace are discussed respectively. Then a set of possible solutions to solve the current problems and alleviate the concerns in this field is offered. Legal remedies that need to be performed by the government are presented as the initial solution. Then encryption is introduced as a strong technical method that may be helpful. Finally, a set of individual measures emphasized as complementary practical necessities. Nevertheless, this study indicates that technology will keep making further changes in the form and concerns of privacy that possibly may outdate these findings in the near future, however, privacy itself will always remain as a cherished social value as it has always been so far.

Effects of Hedonic and Utilitarian Shopping Satisfaction on Mall Consumption

Access: Use of this item is restricted to the UNT Community
The modern consumer expects a consumption experience with both hedonic and utilitarian rewards during a single visit to the mall. The orchestrating of both hedonic and utilitarian benefits in one visit challenges mall management and retailers to deliver the maximum shopping experience. This study seeks to reveal relationships among six variables: demographic characteristics, mall shopping orientation, mall perception, hedonic satisfaction, utilitarian satisfaction, and mall consumption. The intercept survey was conducted at a major entertainment-themed mall in north Texas. Multiple regression analyses (N = 202) indicate that demographic characteristics and mall shopping orientation were significant predictors of mall perception. Also, two mall perception factors (Sensation and Physical Environment) were predictors of hedonic and utilitarian mall shopping satisfaction. However, hedonic and utilitarian mall shopping satisfaction were found not to predict mall consumption in terms of cross-shopping, money spent, and time spent.

Dna Profiling of Captive Roseate Spoonbill (Ajaia Ajaja) Populations As a Mechanism of Determining Lineage in Colonial Nesting Birds. (open access)

Dna Profiling of Captive Roseate Spoonbill (Ajaia Ajaja) Populations As a Mechanism of Determining Lineage in Colonial Nesting Birds.

Roseate spoonbills are colonial nesting birds with breeding grounds extending from the United States Gulf coast to the pampas of Argentina. The U.S. population suffered a severe bottleneck from 1890 to 1920. The population's recovery was slow and partially credited to migrations from Mexican rookeries, but a gene pool reduction would be expected. Five polymorphic Spoonbill autosomal short tandem repeat (STR) loci [three (GAT)n, one (AAAG)n and one (GT)n] and one Z/W-linked microsatellite exhibiting sex-specific dimorphism were isolated and characterized. The Z/W-linked STR locus accurately confirmed the sex of each bird. Allelic profiles for 51 spoonbills obtained from Dallas (Texas), Fort Worth (Texas) and Sedgwick County (Kansas) zoos revealed a non-continuous distribution of allele frequencies, consistent with the effects of a population bottleneck. Allelic frequencies also differed significantly between the isolated zoo populations. Although extra-pair copulations were suspected and difficult to document, zoos commonly used observational studies of mating pairs to determine familial relationships among adults and offspring. STR parentage analysis of recorded family relationships excluded one or both parents in 10/25 cases studied and it was further possible to identify alternative likely parents in each case. Mistaken familial relationships quickly lead to the loss of genetic variability in captive …

Bioreactor Landfill Cell Feasibility Study ' Reference to City of Denton Subtitle-D Permit #1590A Landfill (open access)

Bioreactor Landfill Cell Feasibility Study ' Reference to City of Denton Subtitle-D Permit #1590A Landfill

The City of Denton Landfill, Permit #1590A, utilizes “Dry-Tomb” techniques for disposal and promotion of municipal solid waste stabilization, as described by the Resource Conservation and Recovery Act (RCRA) prohibition in 40 CFR. Bioreactor research suggests re-circulating leachate increases biodegradation rates and reduces long-term monitoring from fifty years to less than ten years. Current procedures that are followed at Denton's landfill, literature review and the use of the Hydrologic Evaluation of Landfill Performance (HELP) model, suggest that a bioreactor landfill cell is worthy of further research. Re-circulating leachate and augmenting it with additional liquid will increase biodegradation and the need to design and build a landfill gas collection system to capture methane for energy recovery uses.

Use of Satellite Imagery and GIS to Model Brood-Rearing Habitat for Rio Grande Wild Turkey Populations Occurring in the Western Cross Timbers Region of Texas

Access: Use of this item is restricted to the UNT Community
Remote sensing and GIS have become standard tools for evaluating spatial components of wildlife habitats. These techniques were implemented to evaluate Rio Grande wild turkey (Meleagris gallopavo) poult-rearing habitat in the Western Cross Timbers region of Texas. Texas Parks and Wildlife (TPWD) random roving turkey counts for 1987-1989 and 1998-2000 were selected, indicating locations where hens with poults were observed. Satellite imagery from 1988 and 1999 was classified and then processed with Patch Analyst. To add robustness, stream, road and census population densities were also evaluated for each turkey location. Analysis of the 1988 canopy cover image, comparing observed locations with randomly-selected habitat cells (N = 20) indicated significant differences (p <.05) for patch edge variables. Mean patch edge was significantly greater for habitat locations where hens with poults were observed than for those selected at random. Spatial data for 1999 did not indicate a significant difference (p < .05) between sampling groups (observed vs. random, N = 30). Significant differences (p <.05) did occur for turkey locations observed in both 1988 and 1999 (N = 7). This demonstrates the adaptability of wild turkey hens, as habitats change over time, hens continued to visit the same locations even though the …
