The calcination of calcium carbonate in a cement or a lime kiln uses approximately two to four times the theoretical quantity of energy predicted from thermodynamic calculation depending upon the type of the kiln used (1.4 x 10^6 Btu/ton theoretical to 6 x 10^6 Btu/ton actual). The objective of this research was to attempt to reduce the energy required for the calcination by 1. decreasing the calcination temperature of calcium carbonate, and/or 2. increasing the rate of calcination at a specific temperature. Assuming a catalytic enhancement of 20 percent in the industrial applications, an energy savings of 300 million dollars annually in the United States could be reached in the cement and lime industries. Three classes of compounds to date have shown a positive catalytic effect on the calcination of calcium carbonate. These include alkali halides, phospho- and silico-molybdate complexes, and the fused carbonates system.

A large body of research has depicted relative arousal of the left and right cerebral hemispheres as related to utilization of particular defensive coping styles, level of anxiety, and perceptual styles. The right and left hemispheres are also presented in the literature as differing in visual-spatial and verbal-auditory short term memory abilities. The present research studied 127 right handed undergraduates' relative performance on forward spatial and digits memory spans in relation to hemispheric lateralization and other perceptual and personality variables hypothesized in the literature to be related to hemispheric arousal. It was hypothesized that the forward spatial and digit memory spans would display asymmetrical sensitivity to hemispheric arousal. That is, in a series of successive factor analyses, a hemispheric balance factor, a trait anxiety factor, and a short term memory factor would emerge. The three factors were hypothesized to be unrelated to each other. During an initial group pretesting, subjects were given pencil and paper measures of handedness, trait anxiety, and several defensive coping styles. During a second individual testing, subjects were administered measures of short term memory, field independence, and a computerized presentation of geometric designs which measured the subjects ability to detect differences which occurred at either the …

Walker Percy differs from other American novelists in that he started writing fiction relatively late in life, after being trained as a physician and after considerable reading and writing in philosophy. Although critics have appreciated Percy's skills as a writer, they have seen Percy above all as a novelist of ideas, and, accordingly, the majority of critical articles and books about Percy has dealt with his themes, especially his philosophical themes, as well as with his philosophical sources. This study explores, therefore, the critical response to philosophical ideas in Percy's five novels to date, as evidenced first by reviews, then by the later articles and books. The critical response developed gradually as critics became aware of Percy's aims and pointed out his use of Christian existentialism and his attacks upon Cartesianism, Stoicism, and modern secular gnosticism. These critical evaluations of Percy's philosophical concerns have sometimes overshadowed interest in his more purely artistic concerns. However, the more a reader understands the underlying philosophical concepts that inform Percy's novels, the more he may understand what Percy is trying to say and the more he may appreciate Percy's accomplishment in expressing his philosophical ideas so skillfully in fictional form. Critics and readers may …

The objectives of this investigation were two-fold. The first was to determine the personal characteristics of Bibliographic Network Coordinators, both past and present; the second was to compare these identified characteristics with those of persons working in traditional library positions at comparable levels of responsibility.

In the present study alpha-receptor modulation of coronary flow and cardiac function was examined in exercising dogs, chronically instrumented to measure: circumflex blood flow velocity (CFV), heart rate (HR), global left ventricular function (LVP and dP/dt Max) and regional left ventricular function (%SL and dL/dt (s)max). During exercise, local adrenergic blockade was produced by intracoronary injection of 1.0 mg phentolamine ( anon-specific alpha-antagonist) or .5 mp prazosin. Exercise significantly increased HR, LVP, dP/dt max, CFV, %SL and dL/dt (s)max. Neither alpha-antagonist produced changes in HR, LVP or %SL; however, both phentolamine and prazosin produced significant increses in dP/dtmax, CFV and dL/dt(s)max of the alpha-blocked region, when compared to their exercise level before alpha-blockade. It is suggested that an alpha1-adrenergic vasoconstriction limits coronary vasodilation and, thereby, cardiac function during exercise.

This research was designed to develop and evaluate an automated alternative to the Box-Jenkins method of forecasting. The study involved two major phases. The first phase was the formulation of an automated ARIMA method; the second was the combination of forecasts from the automated ARIMA with forecasts from two other automated methods, the Holt-Winters method and the Stepwise Autoregressive method. The development of the automated ARIMA, based on a decision criterion suggested by Akaike, borrows heavily from the work of Ang, Chuaa and Fatema. Seasonality and small data set handling were some of the modifications made to the original method to make it suitable for use with a broad range of time series. Forecasts were combined by means of both the simple average and a weighted averaging scheme. Empirical and generated data were employed to perform the forecasting evaluation. The 111 sets of empirical data came from the M-Competition. The twenty-one sets of generated data arose from ARIMA models that Box, Taio and Pack analyzed using the Box-Jenkins method. To compare the forecasting abilities of the Box-Jenkins and the automated ARIMA alone and in combination with the other two methods, two accuracy measures were used. These measures, which are free …

The purpose of this investigation was to determine the prevalence of specific learning disabilities in school-aged hearing impaired children based on the proposed theoretical definition of the National Joint Committee for Learning Disabilities (1981) and the theoretical definition constructed by the Canadian Association for Children and Adults with Learning Disabilities (1981). The operationalization of these theoretical definitions, coupled with the current operational definition issued by the Texas Education Agency (1983), formulated the investigative framework.

The present investigation involved the development of a psychobiologic profile of individuals who experience exercise-related mood-enhancement and those who do not. The sample (N=301) consisted of students participating in 10-week exercise classes at North Texas State University. All subjects completed pre-test inventories assessing various psychological (i.e., trait anxiety and depression, attitude toward physical activity, self-estimation of physical ability and attraction to physical activity, expectancies of health benefits from exercise, and self-motivation) and biological (i.e., aerobic capacity and body fat percentage) variables. Trait anxiety and depression were also assessed before and after the 10-week exercise program and state anxiety and depression were assessed on an acute basis on two separate occasions during the program. Multivariate analysis of variance and discriminant function analysis were employed to determine which variables maximally discriminated between individuals who experienced mood-elevations following exercise and those who did not enjoy such rewards. The hypothesis that these two groups of individuals differ significantly from each other was not upheld by the results; thus, an overall psychobiologic profile could not be developed. However, the data did reveal that individuals who held a more positive attitude toward physical activity for the purpose of health and fitness reduced their state anxiety and …

This study identified the number of learning projects undertaken by thirty-eight retired educators and examined the extent to which these experiences were associated with the body weight and the exercise patterns of the subjects. A list of 1091 names of retired educators was obtained and 400 names were randomly selected to receive a brief survey seeking responses to demographic, personal and miscellaneous questions relating to their efforts to continue to pursue learning. Interviews were arranged with thirty-eight subjects who met established criteria. The 19 8 3 Metropolitan Height and Weight Tables were used to estimate weight characteristics and a probe sheet was designed to identify the number of hours spent exercising in activities vigorous enough to increase heart beat. In-depth interviews were conducted by the investigator using the questions from Tough's Interview Schedule for Studying Some Basic Characteristics of Learning Projects, and the probe sheet designed by the investigator. The interviews focused on the efforts to continue learning during the past twelve months and on the participation in vigorous exercise during the past twelve months. Findings were analyzed by computing t-tests for independent means and the Pearson product moment method of correlation. Comparisons of the results from this study were …

One characteristic of abused children that is often observed but not yet empirically examined is social hypervigilance. In this study, 20 abused and 20 distressed children were compared using WISC-R subtests, two measures of locus of control and need for attention.

This study focuses on the praeceptor amoris, or teacher of love, as that persona appears in English poetry between 1500 and 1660. Some attention is given to the background, especially Ovid and his Art of Love. A study of the medieval praeceptor indicates that ideas of love took three main courses: a bawdy strain most evident in Goliardic verse and later in the libertine poetry of Donne and the Cavaliers; a short-lived strain of mutual affection important in England principally with Spenser; and the love known as courtly love, which is traced to England through Dante and Petrarch and which is the subject of most English love poetry. In England, the praeceptor is examined according to three functions he performs: defining love, propounding a philosophy about it, and giving advice. Through examining the praeceptor, poets are seen to define love according to the division between body and soul, with the tendency to return to older definitions in force since the troubadours. The poets as a group never agree what love is. Philosophies given by the praeceptor follow the same division and are physically or spiritually oriented. The rise and fall of Platonism in English poetry is examined through the praeceptor …

This study was conceived as an attempt to determine .and analyze factors deterring participation in continuing professional education among social workers in environments where continuing education for relicensure is mandatory and voluntary. The specific research design implemented to complete this study was the ex-post facto descriptive design. The sample included 106 social workers randomly selected in the state of Texas where continuing education is mandatory and 94 social workers in the state of Louisiana where continuing education is voluntary. The instrument used was the Deterrent to Participation Scale developed by Scanlan (1983) and a demographic inventory. Scanlan (1983) earlier identified six factors deterring participation in continuing professional education: Disengagement, Lack of Quality, Family Constraints, Cost, Lack of Benefit, and Work Constraints. The study concluded that social workers in both states considered work constraint as a major factor deterring participation in continuing professional education. Also the factors of cost and lack of quality were also considered as crucial barriers in their efforts to participate in continuing professional education. The Wilks' multivariate test of significance of the means and univariate F tests at alpha level p < .05 revealed differences in the combined mean scores of social workers in both states when …

This study delineates the basic concepts and analytical techniques of contemporary French structuralists, namely Levi-Strauss, Lacan, Barthes, Althusser, and Foucault, and critically examines the contribution of their formulations to sociological theory and the implication of such formulations on the methodological orientation in sociology.

Bacillus subtilis (ATCC 19659) were damaged by exposure to various concentrations of glutaraldehyde, as shown by decreased germination rates. The damage caused was repaired or otherwise obviated by the presence of sodium lactate in the holding medium. When two different salts of lactic acid were compared for ability to overcome the effect of glutaraldehyde, it was found that calcium salt of lactate was more effective than the sodium salt. The damage repair system involved l-alanine, lactate and either the sodium or calcium ions. The study involved in determining the difference in efficiency of spore repair was due to an organic or an amino acii snowed that the presence of two carboxylic functional groups did not effectively alter the reactivity.

This study utilized ethnographic methodology to describe the communicative interactional patterns in families with a member who has breast cancer. Three breast cancer patients whose families were between the adolescent and launching of children developmental lifestage (McGoldrick & Carter, 1982) were chosen for the study. Data were collected from a series of three interview sessions over a period of four weeks with a two week time lapse between each of the interview sessions. Interview sessions were conducted in the families' homes by the researcher. All interviews were video and audio tape recorded for the purpose of preserving data for transcribing and coding. Research questions examined individual perception of meaning in regard to the disease, the structure and organization of the family in relation to the illness, and the effects of family communicative interaction on the course and management of the disease. Findings indicated that family members' responses to the diagnosis of "breast cancer were influenced by multi-generational "beliefs. All three families formulated a collective belief which supported the mother's belief about the disease. Each of the three families were mother-centered, and each mother seemed to use a metacommunicative approach to mediating family transactions. Each of the three fathers were reported …

In a three stage investigation the relationship between personality type and the use of learning as a coping device during the life transitions of adults was studied. Based on the assumption that a paper and pencil device could be constructed to achieve the same or nearly the same results that have been achieved through interviews with adult learners, the first two stages of this investigation involved the construction and validation of an instrument, the Adult Development Learning Inventory (ADLI), to measure the use of learning during life transitions of adults. The inventory has five subsections: a demographic profile, Life Events, Coping Strategies, Learning Activities, and Adulthood Tasks. Content validity of the ADLI was established through both the theory based in adult learning and developmental psychology and the panel of experts. Construct validation tools included principal component factor analysis and the Kruskal-Wallis ANOVA with age as the variable of discrimination. The instrument was capable of differentiating among age groups' perception of the tasks in the adult life cycle. For internal consistency, reliability estimates ranged from .83 to .94 for the subsections of the ADLI. Stage III of the investigation explored the relationship between the ADLI and personality as measured by the …

The problem of this study was to determine which of a list of forty-seven art competencies designed by the North Carolina Department of Public Instruction for K-12 art specialists were most essential for early childhood and intermediate elementary classroom teachers. Four-point Likert-type scaled instruments were designed and sent to three types of North Carolina educators: (a) 200 elementary classroom teachers, stratified into two equal subgroups of early childhood and intermediate teachers; (b) 100 K-12 art specialists; and (c) all art teacher educators employed at colleges and universities with state approved programs in art education. These subjects were asked to respond to the relevance of each competency for the elementary classroom teacher.

The problem of this study was the perceptions of Texas public school teachers and principals regarding recommendations for educational reform made in April, 1983, by the National Commission on Excellence in Education. Purposes included determining those perceptions and investigating differences between them, differences among teachers1 perceptions, and differences among principals' perceptions relative to specific categories of recommendations and specific biographic variables. A random sample of 460 teachers and 180 principals, stratified equally among the state's twenty education regions, was selected from the population of public school teachers and principals on computer at the Texas Education Agency, Austin, Texas. The actual number of respondents included 224 teachers and 91 principals, or 49 percent and 51 percent respectively. The instrument used was an attitude scale developed by the investigator. The thirty-nine original recommendations made by the Commission were converted into 118 specific recommendations, more precise and easier to read according to a jury of experts. An. analysis of variance was calculated for hypotheses one, two, five, and six, and t values were calculated for hypotheses three and four. The study was organized into five chapters including the "Introduction," "Review of the Related Literature," "Procedures for Collection and Analysis of Data," "Analysis of …

This paper concentrates on the viability of using metaphor as a teaching tool in the English as a Second Language classroom. In doing so, a semantically-based theory of metaphor, like that presented by Lakoff and Johnson (1980), is employed as a base for the examination. Such a theory of metaphor presents a dramatic shift from theories, especially Aristotle's, of the past. The theory of metaphor proposed by Lakoff and Johnson contends that language is essentially metaphorical and that much of our 'commonsense' knowledge about the world is derived from interpretations of reality and is manifested in metaphors central to a culture and its language. If this theory is true, then it stands to reason that a student attempting to learn English as a Second Language could profit greatly from metaphor instruction because such instruction would aid all areas of the language acquisition process.

The purpose of this study was to identify childrearing attitudes of Mexican-American mothers with children ages three to five years of age. Specifically the first purpose of this study was to determine childrearing attitudes of Mexican-American mothers with ten years of education or fewer and Mexican-American mothers with eleven years of education or more as identified by the Parent As A Teacher Inventory (PAAT). The second purpose was to identify the relationship of the following demographic variables to childrearing attitudes: mother's age, mother's marital status, family income, sex of child, age of child, access to child, generational status, mother's language and mother's ethnicity. The PAAT and the Parent Information Questionnaire were administered to 112 Mexican-American mothers; 54 Mexican- American mothers with ten years of education or fewer and 58 Mexican-American mothers with eleven years of education or more. The population from which these subjects were drawn were mothers from Mexican-American communities in a North Texas county. Responses on the sample were analyzed using multivariate statistics. Based on the analysis of the data, the following conclusions seem tenable. 1. The Mexican-American mothers with eleven years of education or more have childrearing attitudes which are more positive than the Mexican-American mothers with …

This dissertation establishes that the Evangelical Anabaptists lived a noticeably distinctive Christian life when compared with their peers, accounts for their committed pursuit of holiness, and describes the outcome of that commitment. The sources used include the arranged archival source material in the Tauferakten, confessions, tracts, letters, debates, martyrologies, miscellaneous writings of the Anabaptists, and subsequent scholarship on the subject.

The continued publication of articles concerning drama and theatre in scholarly periodicals has resulted in the "loss" of much research due to the lack of retrieval tools. This work is designed to partially fill this lack by cassifying the articles found in fourteen current periodicals using Trussler's taxonomy. This bibliography could also be updated on a regular basis. The issues that are presently not available through the North Texas State University Libraries could be ordered, classified and appended to this work. In short, this thesis is a start toward the opening of the source material held by the campus libraries. But it is only a start. There is still a treasure trove yet to be developed.

This study is the first comprehensive analysis of the fatal woman motif in the writings and art of Edvard Munch from the early 1890s to 1909. It uses a background of the women in the artist's life as well as the literary and artistic worlds in which Munch participated. Following separate accounts of Munch's relationships with five women, the manner in which the artist characterizes each as a fatal woman in his writings and art is discussed and analyzed. Next, the study describes the fatal woman motif in late nineteenth century art and literature. It begins with a discussion of the origin of the Symbolist and Decadent Movements and an ideological examination of the fatal woman motif as it is manifested in the writing and art of these two groups. In addition, it compares Munch's visual manifestations of the femme fatale with the manner in which the artist's contemporaries depicted her. Finally, this study describes two groups of men with whom Munch was particularly close: the Christiania Bohéme and the Schwarzen Ferkel Circle. An examination of the literary works of these men helps to determine the way in which they affected Munch's pictorial perception of the fatal woman.
