Perceptions of Work Group and Managerial Behaviors as Antecedents of a Salesperson's Commitment, Performance, and Turnover (open access)

Perceptions of Work Group and Managerial Behaviors as Antecedents of a Salesperson's Commitment, Performance, and Turnover

Theoretically grounded and empirically testable conceptualizations that offer alternative explanations regarding sales force performance and turnover can: (a) enhance understanding regarding these pivotal outcomes, and (b) augment an organization's capability to increase sales and decrease turnover. The study advances one such explanation by conceptualizing and testing a perceptual model that links a salesperson's psychological climate dimensions to organizational commitment, performance, and turnover. The framework the study proposes respecifies the leadership and work group dimensions of psychological climate into four distinct perceptions (i.e., a salesperson's perceptions regarding the behaviors of work group, sales manager, senior management, and non sales employees in the organization). These climate dimensions are posited to influence positively a salesperson's organizational commitment which consequently influences positively the salesperson's effort and intention to stay with the organization. The proposed outcomes of organizational commitment result in increased performance and decreased turnover. Success beliefs and perceived behavioral control are posited to moderate the relationship between the salesperson's organizational commitment and effort. The study tests the hypothesized relationships on a sample of salespersons belonging to a telecommunications organization utilizing path and hierarchical regression analyses.

Thermodynamic Properties of Nonelectrolyte Solutes in Ternary Solvent Mixtures (open access)

Thermodynamic Properties of Nonelectrolyte Solutes in Ternary Solvent Mixtures

The purpose of this dissertation is to investigate the thermodynamic properties of nonelectrolyte solutes dissolved in ternary solvent mixtures, and to develop mathematical expressions for predicting and describing that behavior in the solvent mixtures. Thirty-four ternary solvent systems were studied containing either alcohol (1-propanol, 2-propanol, 1-butanol, and 2-butanol), alkane (cyclohexane, heptane, and 2,2,4-trimethylpentane) or alkoxyalcohol (2-ethoxyethanol and 2-butoxyethanol) cosolvents. Approximately 2500 experimental measurements were performed. Expressions were derived from the Combined Nearly Ideal Multiple Solvent (NIMS)/Redlich-Kister, the Combined Nearly Ideal Multiple Solvent (NIMS)/Bertrand, Acree and Burchfield (BAB) and the Modified Wilson models for predicting solute solubility in ternary solvent (or even higher multicomponent) mixtures based upon the model constants calculated from solubility data in sub-binary solvents. Average percent deviation between predicted and observed values were less than 2%, documenting that these models provide a fairly accurate description of the thermodynamic properties of nonelectrolyte solutions. Moreover, the models can be used for solubility prediction in solvent mixtures in order to find the optimum solvent composition for solubilization or desolubilization of a solute. From a computational standpoint, the Combined Nearly Ideal Multiple Solvent/Redlich-Kister equation is preferred because the needed model constants can be calculated with a simple linear regressional analysis. Model constants …

Timed vs. Untimed Initiation Intervals and the Effects of Confidence on a Golf Putting Task (open access)

Timed vs. Untimed Initiation Intervals and the Effects of Confidence on a Golf Putting Task

Low, moderate, and high handicap golfers, while wearing glasses with a blinder on the side, attempted 9 putts differing in length from 5 to 21 ft under timed (less than 3.5s from grounding of club to initiation of back swing) and untimed conditions in a counterbalanced design. Confidence ratings were taken prior to and following each putt. The results revealed a significant condition by handicap group interaction (p=.021). The lower handicap group had a more consistent and lower initiation interval duration than did the moderate and high handicap players. Post interviews determined that 33 of the 35 golfers felt more comfortable in the untimed condition. However, golfers' confidence levels were not significantly different in the untimed condition as compared to the timed condition.

Reverberating Reflections of Whitman: A Dark Romantic Revealed (open access)

Reverberating Reflections of Whitman: A Dark Romantic Revealed

Walt Whitman has long been celebrated as a Romantic writer who celebrates the self, reveres Nature, claims unity in all things, and sings praises to humanity. However, some of what Whitman has to say has been overlooked. Whitman often questioned the goodness of humanity. He recognized evil in various shapes. He pondered death and the imperturbability of Nature to human death. He exhibited nightmarish imagery in some of his works and gory violence in others. While Whitman has long been called a celebratory poet, he is nevertheless also in part a writer of the Dark Romantic.

Strain, Social Support, and the Meaning of Work for New Mothers

The purpose of this study was to describe the relative importance of aspects of the occupational environment in predicting personal strain and changes in the meaning of work (perceived changes in work role salience and work values) during the transition to parenthood. The aspects of the work environment under investigation were: work interference with family, family interference with work, supervisor support for combining work and family, and organization support (respect, separation, and integration types). Control variables were husband support, an important factor in adjustment during the transition to parenthood, and socioeconomic status. A sample of 118 women in dual career couples with one child under two years of age were recruited through childcare centers and newspaper announcements. The sample was predominantly Caucasian and middle or upper-middle class. Subjects completed self-report questionnaires. Hypotheses were tested using hierarchical multiple regression. Results of this study provided partial support for the hypothesis that workplace support and work/family interference would contribute to personal strain. Only family interference with work emerged as a significant predictor. The results of this study provided partial support for the hypothesis that husband support, workplace support, and work/family interference would contribute to change in work values.

The Effects of Modeling, Roleplaying and Feedback on the Performance of Teachers of Children with Autism (open access)

The Effects of Modeling, Roleplaying and Feedback on the Performance of Teachers of Children with Autism

Teachers providing treatment to children with autism are responsible for implementing numerous procedures. Teacher training has not been addressed extensively in the literature. This study employed a multiple baseline design to evaluate the effects of a training package incorporating modeling, roleplaying and feedback on teacher performance. Results indicated that the teacher implemented correct teaching episodes following training. Changes in teacher performance were only observed when the training package was applied to each setting and skill area. As a result of changes in teacher behavior, the child demonstrated an increase in the number of desired responses. Results are discussed in the context of generalization, training package components, cost-benefit of single-subject designs, and limitations of the study.

The Power of One: Bonnie Singleton and American Prisoners of War in Vietnam (open access)

The Power of One: Bonnie Singleton and American Prisoners of War in Vietnam

Bonnie Singleton, wife of United States Air Force helicopter rescue pilot Jerry Singleton, saw her world turned upside down when her husband was shot down while making a rescue in North Vietnam in 1965. At first, the United States government advised her to say very little publicly concerning her husband, and she complied. After the capture of the American spy ship, the U.S.S. Pueblo by North Korea, and the apparent success in freeing the naval prisoners when Mrs. Rose Bucher, the ship captain's wife, spoke out, Mrs. Singleton changed her opinion and embarked upon a campaign to raise public awareness about American prisoners of war held by the Communist forces in Southeast Asia. Mrs. Singleton, along with other Dallas-area family members, formed local grass-roots organizations to notify people around the world about the plight of American POWs. They enlisted the aid of influential congressmen, such as Olin "Tiger" Teague of College Station, Texas; President Richard M. Nixon and his administration; millionaire Dallas businessman Ross Perot; WFAA television in Dallas; and other news media outlets worldwide. In time, Bonnie Singleton, other family members, and the focus groups they helped start encouraged North Vietnam to release the names of prisoners, allow mail …

Problem-Based Learning for Training Teachers of Students with Behavioral Disorders in Hong Kong

This study attempts to explore the perceived value of Problem-Based Learning (PBL) in training teachers of students with behavioral disorders (E/BD) in Hong Kong. It represents an effort to improve the predominately lecture focussed approach adopted in many preparation programs. Data on the training needs of Hong Kong teachers were also acquired and 31 knowledge/skills areas related to teaching students with E/BD were identified. Subjects viewed the PBL approach as dynamic, interesting and incentive driven. It develops skills involved in group learning, self-directed learning, use of information resources and problem-solving. Most important, teachers felt they were supported to explore the practical problems they personally encountered in the classroom and actions they could take to resolve them. Difficulties in using PBL included a lack of resources and the tendencies of most Chinese students to accept rather than challenge others' ideas.

Theological Distance Learning through Trinity College and Theological Seminary: Programs, Problems, Perceptions, and Prospects

An international survey was conducted to assess theological higher education via distance learning as perceived by graduates of Trinity College and Theological Seminary's (Trinity) doctoral programs. The purpose of the study was to determine student-perceived strengths and weaknesses of Trinity's doctoral-level distance education theology programs. Also, the future of distance-learning mediated programs of theological higher education was speculated. A random sample of 400 doctoral recipients was selected from the population of 802 doctoral recipients who graduated from Trinity between the years of 1969 and March 1998. A mailed questionnaire was used to collect data. A total of 203 (50.0%) were returned. Frequency counts, percentage distributions, and chi-square tests of goodness-of-fit were employed to analyze the data. A profile of the modal type of student who would participate in theological distance education at the doctoral level was developed from the demographic variables queried. Responses to questions regarding respondents' educational experiences and coursework were solicited as well. Respondents identified five primary strengths of Trinity's distance education doctoral programs as: the convenience of the program; the immediate application of course content to personal and professional endeavors; the quality of education provided; the Biblical groundedness of the curricula, the materials, and the faculty; and …

Why Orville and Wilbur Built an Airplane (open access)

Why Orville and Wilbur Built an Airplane

This dissertation comprises two sections. The title section collects a volume of the author's original poetry, subdivided into four parts. The concerns of this section are largely aesthetic, although some of the poems involve issues that emerge in the introductory essay. The introductory essay itself looks at slightly over three centuries of poetry in English, and focuses on three representative poems from three distinct periods: the long eighteenth century and the Romantic period in England, and the Post-war period in the United States. John Dryden's translation of Ovid's "Cinyras and Myrrha," John Keats' "Ode to a Nightingale," and James Dickey's "The Sheep Child," whatever their stylistic and aesthetic differences may be, all share a concern with taboo. Each of the poems, in its own way, embraces taboo while transgressing societal norms in order to effect a synthesis that merges subject and object in dialectical transcendence. For Dryden, the operative taboo is that placed on incest. In his translation of Ovid, Dryden seizes on the notion of incest as a metaphor for translation itself and views the violation of taboo as fructifying. Keats, in his Nightingale ode, toys with the idea of suicide and reconstructs a world both natural and mythic …

A Comparison of Points Versus Sounds as Reinforces in Human Operant Research (open access)

A Comparison of Points Versus Sounds as Reinforces in Human Operant Research

Research shows that human operant behavior typically differs from non-human operant behavior on schedules of reinforcement. These differences in performance may be related to differences between the experimental preparations used to study human and non-human operant behavior. One such difference is the type of reinforcer used. This experiment analyzed the differential effects of points alone, points backed up by money, and sounds on schedule performance of human subjects. Results show that sounds generated moderate rates of responding, capable of change in either direction. When points backed up with money were the reinforcers, however, high rates of behavior were generated, disrupting the previously established baseline performance. This suggests that while points may be effective in generating high rates of behavior, they may be ineffective in producing sensitive baselines needed to study human operant behavior on schedules of reinforcement.

Sexual Identity Development and Heterosexual Mistrust: An Exploratory Study (open access)

Sexual Identity Development and Heterosexual Mistrust: An Exploratory Study

The sexual identity development process in gay men was the focus of this study. It was theorized that, as a result of negative experiences with the dominant heterosexual culture, gay men might feel mistrustful of heterosexuals in various settings. A new theoretical construct, that of heterosexual mistrust, was identified and explored. A new scale, the Heterosexual Mistrust Inventory (HMI), was created to measure this construct. Gay male subjects' stage of homosexual identity formation (HIF) was also determined. Results indicated that heterosexual mistrust existed to a significantly stronger degree among gay men than among heterosexual men. Heterosexual mistrust was strongly related to stage of HIF. The various settings in which heterosexual mistrust was found to occur were discussed. Implications for current knowledge about HIF and about cultural belief systems unique to gay men were identified and explored.

Father Absence, Onset of Menarche, and Body Dissatisfaction: Importance of Father Absence

Relationships between body dissatisfaction, dieting methods, father absence, and puberty timing were investigated in this study. Participants included adolescent females from Wave 1 of the National Longitudinal Survey of Adolescent Health. Logistic regression results indicated that girls without a biological father in the home were significantly more likely to have an early onset of puberty than on-time or late. Girls who experienced early puberty exhibited higher levels of body dissatisfaction, but didn't use more dieting methods. Early onset girls more likely used dieting methods if their biological father was present than absent; however, no significant difference in body dissatisfaction was shown. A negative relationship with fathers indicated more body dissatisfaction. None of the attained findings were found when the biological mother was absent, and having a stepfather did not seem to matter. Evidence was revealed that fathers play a role in their daughters' view of their own bodies.

The Effects of Brief Exposure to Non Traditional Media Messages on Female Body Image (open access)

The Effects of Brief Exposure to Non Traditional Media Messages on Female Body Image

Body image may be defined as the perception or attitude one has regarding the appearance of his or her body. Body image concerns are not only central to the diagnostic criteria of eating disorders, but also create distress for nonclinical populations. Females (n = 167) from three universities participated in a study by completing the Eating Disorder Inventory - 2 (Garner, 1991) and the Figure Rating Scale (Stunkard, Sorenson, & Schulsinger, 1983); watching a video; and then completing the instruments again. Subjects in the treatment group (n = 89) viewed a video designed to increase awareness of unrealistic body sizes and shapes seen in the media (Kilbourne, 1995). Subjects in the comparison group (n = 77) viewed a video unrelated to female body image.

Parents' Motivation in Registering their Child for Gymnastics

This study examined factors that motivate parents to involve their children in organized gymnastics programs. A questionnaire based on McCullagh et al.'s (1993) study of recreational soccer players was used along with open-ended questions. The questionnaire was administered to parents of children who were involved in a private gymnastics club. Descriptive statistics of 156 surveys showed that fitness, skill development, and fun were most frequently cited reasons for parents in their decision to enroll and keep their child in gymnastics programs. Competition was the least important factor. ANOVA showed that competition and team membership factors were more important to the parents of competitive gymnasts than parents of recreational gymnasts. Coaches and youth sport program organizers could use these findings to develop and market youth activity programs.

Picosecond Dynamics of Free-Carrier Populations, Space-Charge Fields, and Photorefractive Nonlinearities in Zincblende Semiconductors (open access)

Picosecond Dynamics of Free-Carrier Populations, Space-Charge Fields, and Photorefractive Nonlinearities in Zincblende Semiconductors

Generally, nonlinear optics studies investigate optically-induced changes in refraction or absorption, and their application to spectroscopy or device fabrication. The photorefractive effect is a nonlinear optical effect that occurs in solids, where transport of an optically-induced free-carrier population results in an internal space-charge field, which produces an index change via the linear electrooptic effect. The photorefractive effect has been widely studied for a variety of materials and device applications, mainly because it allows large index changes to be generated with laser beams having only a few milliwatts of average power.Compound semiconductors are important photorefractive materials because they offer a near-infrared optical response, and because their carrier transport properties allow the index change to be generated quickly and efficiently. While many researchers have attempted to measure the fundamental temporal dynamics of the photorefractive effect in semiconductors using continuous-wave, nanosecond- and picosecond-pulsed laser beams, these investigations have been unsuccessful. However, studies with this goal are of clear relevance because they provide information about the fundamental physical processes that produce this effect, as well as the material's speed and efficiency limitations for device applications.In this dissertation, for the first time, we time-resolve the temporal dynamics of the photorefractive nonlinearities in two zincblende semiconductors, …

Academic Lineage and Student Performance in Medical School

This research investigated the association between academic lineage and student performance in medical school. The purposes of the study were to: (1) determine whether the Carnegie classifications of medical school applicants' institutions of origin are associated with academic performance in medical school; (2) consider the relationship between the admission selectivity of the schools of origin and the academic performance of medical school students; (3) compare the performance of medical students from institutions under public governing control with students from privately controlled institutions; and (4) establish a model by which the relative academic strengths of applicants from a variety of undergraduate institutions can be understood more clearly based on the previous performance of medical students from schools with similar institutional characteristics. A review of the literature on medical school admissions was completed and used to develop this research. Medical students from the University of Texas Southwestern Medical Center at Dallas who enrolled between the years 1990 and 1994 and graduated or were dismissed between the years 1994 and 1998 were selected as the sample for the study (n=933). The undergraduate institution of origin for each student was coded based on its Carnegie classification, admissions selectivity group, and whether its governing control …
