The Effectiveness of Speech Recognition as a User Interface for Computer-Based Training
Some researchers are saying that natural language is probably one of the most promising interfaces for use in the long term for simplicity of learning. If this is true, then it follows that speech recognition would be ideal as the interface for computer-based training (CBT). While many speech recognition applications are being used as a means for a computer interface, these are usually confined to controlling the computer or causing the computer to control other devices. The user input or interface has been the recipient of a strong effort to improve the quality of the communication between man and machine and is proposed to be a dominant factor in determining user productivity, performance, and satisfaction. However, other researchers note that full natural interfaces with computers are still a long way from being the state-of-the art with technology. The focus of this study was to determine if the technology of speech recognition is an effective interface for an academic lesson presented via CBT. How does one determine if learning has been affected and how is this measured? Previous research has attempted quantify a learning effect when using a variety of interfaces. This dissertation summarizes previous studies using other interfaces and those …

Sufficient Conditions for Uniqueness of Positive Solutions and Non Existence of Sign Changing Solutions for Elliptic Dirichlet Problems
In this paper we study the uniqueness of positive solutions as well as the non existence of sign changing solutions for Dirichlet problems of the form $$\eqalign{\Delta u + g(\lambda,\ u) &= 0\quad\rm in\ \Omega,\cr u &= 0\quad\rm on\ \partial\Omega,}$$where $\Delta$ is the Laplace operator, $\Omega$ is a region in $\IR\sp{N}$, and $\lambda>0$ is a real parameter. For the particular function $g(\lambda,\ u)=\vert u\vert\sp{p}u+\lambda$, where $p={4\over N-2}$, and $\Omega$ is the unit ball in $\IR\sp{N}$ for $N\ge3$, we show that there are no sign changing solutions for small $\lambda$ and also we show that there are no large sign changing solutions for $\lambda$ in a compact set. We also prove uniqueness of positive solutions for $\lambda$ large when $g(\lambda,\ u)=\lambda f(u)$, where f is an increasing, sublinear, concave function with f(0) $<$ 0, and the exterior boundary of $\Omega$ is convex. In establishing our results we use a number of methods from non-linear functional analysis such as rescaling arguments, methods of order, estimation near the boundary, and moving plane arguments.

GABAᴀ Receptors in Rat Whisker Barrel Cortex: Effects of Sensory Deprivation
The GABAergic system in adult sensory cortex is affected by sensory deprivation, but little is known about how this predominant inhibitory system is affected during ontogeny. The present study investigates developmental effects of whisker trimming on GABAa receptors in rat barrel cortex. Rats trimmed for 6 wk beginning at birth and adulthood showed similar decreases in [3H]muscimol binding in deprived relative to non-deprived barrels, suggesting absence of a critical period.

Distorted Time Perception as an Underlying Factor of Psychosis Proneness and Dissociation
Distortions in the perception of time historically have been associated with dissociation and psychosis in clinical populations. However, the relations among dissociation, psychosis, and time perception in sub-clinical populations have not been investigated. In the present study, college undergraduates scoring either normally or deviantly high on the Per-Mag were given a Dissociative Experiences Scale (DES) and a computerized time-estimation/production task. Participants scoring high on the Per-Mag obtained higher scores on the DES than participants scoring low on the Per- Mag. Per-Mag scores also correlated positively with DES scores across 608 total participants screened. The relation between dissociative and psychotic symptomatology is discussed considering dichotomous versus continuous conceptualizations of psychopathology. The effects of intelligence, social desirability, malingering, gender, and post-traumatic stress on the measures used are also discussed.

Upper and Lower Temperature Tolerances of Three Freshwater Game-Fish Species Exposed to Cycling Temperatures
A total of 670 critical thermal maxima (CTMax) and minima (CTMin) were determined for three freshwater fishes acclimated to three constant temperatures and a diel regimen cycling between the lowest and highest acclimation temperatures. In all species temperature tolerance was directly related to acclimation temperature and slopes relating these variables indicate that acclimation temperature has a greater influence on tolerance of low rather than high temperatures. CTMax and CTMin values generated following exposure to 32 days of oscillating temperatures indicate that in general, fishes had temperature tolerance acclimation states consistent with the average temperature and not either the highest or lowest temperature of the diel cycle.

The Influence of Relationship Quality and Preventability of Death on Perceptions of Funerals in Bereaved Adults
Four hundred and thirty-eight participants who had lost a close friend or family in the last 2 years completed questionnaires regarding their experiences with the funeral. Results indicated individuals emotionally close to the deceased person reported higher levels of participation in funeral rituals and greater levels of bereavement adjustment. Those emotionally distant from the deceased person reported greater satisfaction with the funeral. Individuals who viewed the deceased person as a central figure in their lives had greater participation in the funeral. Those who viewed the deceased person as a peripheral figure had higher levels of bereavement adjustment. Additionally, those who viewed the death as unpreventable reported greater satisfaction with the funeral, and had higher levels of bereavement adjustment.

Strategic Reorientation in the Computer Software and Furniture Industries: a Hierarchical Regression Analysis
Insufficient literature exists in the area of incremental and revolutionary change to explain and predict the convergence and reorientation phenomena happening in organizations. The process of strategic reorientation involves the internal organizational complexities of fast-paced (within two years) changes in competitive strategy as a necessary condition coupled with changes in at least two of organization structure, power distribution, and control systems. Antecedent forces believed to influence the discontinuous change process include industry sales turbulence, structural inertia/firm size, firm past financial performance, CEO turnover, top management team turnover, management team heterogeneity, management environmental awareness, and external attributions for negative financial performance. Punctuated equilibrium was the foundational theory for this study in which a strategic reorientation model published in Strategic Management Journal was reconstructed. The research question was: What seem to be the significant time-based antecedent forces or conditions that lead to strategic reorientation? The study used two hierarchical logit regression models to analyze data gathered from COMPUSTAT PC Industrial Data Base and Compact Disclosure (CD-ROM) over the years 1987-1993 from the turbulent computer software and stable furniture industries. Qualitative data were found in 10-K reports and President's Letters in Annual Reports filed with the SEC and available on Laserdisclosure. The sample, …

Intellectuals and National Socialism: The Cases of Jung, Heidegger, and Fischer
This thesis discusses three intellectuals, each from a distinct academic background, and their relationship with National Socialism. Persons covered are Carl Gustav Jung, Martin Heidegger, and Eugen Fischer. This thesis aims at discovering something common and fundamental about the intellectuals' relationship to politics as such. The relationship each had with National Socialism is evaluated with an eye to their distinct academic backgrounds. The conclusion of this thesis is that intellectuals succumb all too easily to political and cultural extremism; none of these three scholars saw themselves as National Socialists, yet each through his anti-Semitism and willingness to cooperate assisted the regime.

In Nomine Domini
In Nomine Domini is an eighteen-minute composition for two chamber orchestras with two soloists using real-time interactive signal processing techniques. The first chamber orchestra is scored for flute (piccolo), English horn, trumpet in C, trombone, two percussionists (cowbells, wood blocks, tenor drum, suspended cymbal, gongs, tam-tam, temple blocks, tambourine, snare drum, timbales, and bass drum), horn in F (soloist), viola, and string bass. The second chamber orchestra is scored for oboe, clarinet in Bb (bass clarinet in Bb), bassoon, tuba, two percussionists (crotales, two marimbas, vibraphone, chimes, and tom-toms), piano (soloist), violin, and cello. Real-time interactive signal processing techniques are achieved through the use of a stereo multiple-effects signal processor and a personal computer running MIDI interactive software. The work is based upon the four-hundred and seventy-five year old in nomine composition tradition begun by John Taverner in the Benedictus of his Mass Gloria tibi Trinitas (1520) and continued in over one-hundred and fifty Renaissance settings. In Nomine Domini consists of three movements: "Taverner* derived from the Benedictus of the Mass Gloria tibi Trinitas (1520), "Byrd" derived from the Benedictus of William Byrd's Five-voice Mass (1592), and "Tye" derived from Christopher lye's In Nomine XIII "Trust" (1578).

Chronically Ill Children: Maternal Stress and Psychological Symptomatology
This study used a parenting stress and coping model to identify predictors of symptomatology for 13 8 mothers of medically compromised children. This model proposed that: child characteristics (severity of the chronic illness and child related parenting stressors); parent characteristics (self-esteem, sense of competence, and parents' perceived stress/distress); and environmental characteristics (social support, general life stressor events, and demographic variables) contribute to psychological symptomatology for these mothers. Multiple regression analysis found a relationship between general life stressor events, severity of the children's chronic conditions, lower satisfaction with social support, lower self-esteem, and younger mothers' ages and greater symptomatology. Trends toward significance were found for more parenting stress and lower parenting sense of competence predicting greater symptomatology. Predicted relationships between family socioeconomic status and parenting daily hassles and symptomatology were not supported.

A Comparison of the Effectiveness of Computer Adaptive Testing and Computer Administered Testing
The problem with which this study is concerned is determining the effectiveness of a computer adaptive test as compared to the effectiveness of using the entire test. The study has a twofold purpose. The first is to determine whether the two test versions generate equivalent scores, despite being of different lengths. The second is to determine whether the difference in time needed to take the computer adaptive test is significantly shorter than the computer administered full test.

Four Types of Day Care and their Effects on the Well-Being of Children
Data gathered from Tyler, Texas, the University of North Texas, and the National Survey of Families and Households (NSFH) were used to compare children from commercial, home, church, and university based day care with children not attending day care. The research group, comprised of children attending day care (N=142), were located using non-probability sampling; those not in day care (the control group) came from the NSFH (N=1775). Data from the research group were weighted to match the control group. The independent and control variables included the child's age, length of time in day care, intellectual functioning; the parent's marital status and social class; the day care's staff to child ratio and the staff's training. All data, except that pertaining to the facility itself, were gathered from the children's parents using a self-report questionnaire. The remaining data were gathered through personal interview by the researcher. The dependent variable was an index of emotional and behavioral problems reported for the child. Overall, children who attended day care had only slightly more problems reported than those who did had not attended day care. When each center was examined separately, the children in home centers had the greatest number of problems, followed by the …

Development and Testing of a Resource-Based Theory of International Entry Mode Choice
A firm can deploy a variety of arrangements (entry modes) like wholly owned subsidiaries, joint ventures, contracts, and export modes to implement its product market strategies in foreign countries. Each of these arrangements entails decisions about the location of production facilities and/or marketing operations, and the type of ownership of these operations. The choice of an entry mode is of strategic importance to a firm because it can involve investment of substantial amount of resources and has a strong bearing on the firm's marketing mix. Due to its strategic importance, the entry mode choice phenomenon has been extensively researched. In the past, seven major theories have been proposed but none is able to explain the choice from the complete set of entry modes. Thus, there exists a gap between the theory and practice of entry mode choice. This study provides breakthrough on two fronts. First, it develops a new theory of entry mode choice grounded in the resource-based perspective of the firm. The theory posits that the decision to locate its production and/or marketing operations in a country is related to the actualizability of the firm's competitive advantage in that country. However, the ownership decision is related to the sustainability …

Testing the Construct Validity of the Sulliman Scale of Social Interest
The purpose of the present study was to further explore evidence for the construct-related validity of the Sulliman Scale of Social Interest (SSSI) through the implementation of both convergent and discriminant procedures. This was done through (a) replicating St. John's 1992 study, (b) extending the findings of that study by incorporating additional psychological measures, and (c) examining SSI itself by means of principal axis factor analytic procedures. First, all nine of the relationships demonstrated between the SSSI and other variables in the St. John (1992) study were replicated in the present study. Second, in extending the findings of that study, 22 of 26 hypothesized relationships between the SSSI and other psychological measures were in the predicted direction. Third, the results of the factor analysis produced three factors labeled "contextual harmony," "positive treatment/response," and "confidence and trust." Taken together, the outcomes of both studies appear to offer some support for the SSI's construct validity and to provide possible directions for future research.

Marital and Social Changes in the Lives of Women who Complete the Ph.D. Degree at Midlife
The percentage of women who receive doctorates has increased by over 300 percent during the past three decades. The consequences of pursuing the Ph.D. degree have always been far reaching and profound, serving as an impetus and springboard for the reconfiguration of one's beliefs, values, and professional life. The purposes of this national study were to ascertain and describe marital and social changes that occurred in the lives of women who were awarded the Ph.D. degree at midlife. A questionnaire was distributed to a sample of three-hundred women who hold the Ph.D. degree and were employed in institutions of higher education in the United States. The study sought to identify the effects of the Ph.D. experience upon the marital relationships, friendships, and social activities of women who completed the degree between the ages of thirty-five and forty-five. Demographic data were collected which were related to their marital status before, during, and after the Ph.D. experience. Both closed and open-ended questions were posed which solicited information pertaining to their post Ph.D. experience. This research reports both quantitative and qualitative findings. The majority of women who complete the Ph.D. experience at midlife undergo and initiate changes in their lives which impact their …
