A Comparison of Three Item Selection Methods in Criterion-Referenced Tests

A Comparison of Three Item Selection Methods in Criterion-Referenced Tests

Date: August 1988
Creator: Lin, Hui-Fen
Description: This study compared three methods of selecting the best discriminating test items and the resultant test reliability of mastery/nonmastery classifications. These three methods were (a) the agreement approach, (b) the phi coefficient approach, and (c) the random selection approach. Test responses from 1,836 students on a 50-item physical science test were used, from which 90 distinct data sets were generated for analysis. These 90 data sets contained 10 replications of the combination of three different sample sizes (75, 150, and 300) and three different numbers of test items (15, 25, and 35). The results of this study indicated that the agreement approach was an appropriate method to be used for selecting criterion-referenced test items at the classroom level, while the phi coefficient approach was an appropriate method to be used at the district and/or state levels. The random selection method did not have similar characteristics in selecting test items and produced the lowest reliabilities, when compared with the agreement and the phi coefficient approaches.

Hostile Environment: A Discriminant Model of the Perceptions of Working Women

Hostile Environment: A Discriminant Model of the Perceptions of Working Women

Date: August 1988
Creator: Kirk, Delaney, J.
Description: This study examines the problem of operationally defining "hostile environment" sexual harassment, ruled a type of disparate treatment actionable under Title VII of the Civil Rights Act by the United States Supreme Court on June 19, 1986. Although the Equal Employment Opportunity Commission defines a hostile environment as an "intimidating, hostile, or offensive work environment," there is no consensus as to what is "offensive" behavior. An extensive review of the literature yielded various attempts to define and ascertain the magnitude of sexual harassment, but the fact that the actual percentages varied indicates that this is a difficult issue to measure. As perception by the victim is the key, this study surveyed 125 working women from all over the United States to determine their perceptions of behaviors that constitute sexual harassment. Discriminant analysis was then used to correctly classify 95% of the women according to their perceptions of having experienced sexual harassment. Using tests for proportions, three hypotheses were found significant. Women who have been sexually harassed are more likely to view sexual harassment as a major problem. Older men are more likely to have their behavior perceived as sexual harassment. In addition, women who have experienced acts such as staring, ...

The Relationship of Temperament and Extraversion-Introversion to Selected Group counseling Outcome Measures

The Relationship of Temperament and Extraversion-Introversion to Selected Group counseling Outcome Measures

Date: August 1988
Creator: Hays, Donald G.
Description: The problem of this study was the determination of the relationship between Myers-Briggs personality temperament and extraversion-introversion, and group counseling norms, as reflected by the group counseling outcome measures: Survey of Attraction to Group, self and leader-report Interpersonal Relationship Rating Scale (IRRS), and Sociometric Choice Status Survey. The Mvers-Briggs Temperament Indicator (MBTI) and the four outcome measures were administered to a sample population of 103 graduate and undergraduate counselor education students after completion of a semester-long group counseling experience. Fifteen groups of five to nine members were surveyed. It was expected that group members whose temperaments were compatible with group counseling norms would be more likely to receive confirmation, support, and acceptance in the group, be attracted to the group, receive higher leader and self-report ratings of interpersonal skills, and be more highly valued by other members than would members whose temperaments were incompatible with group norms. It was also thought that extraverts were more likely to be attracted to the group, receive higher self and leader ratings of interpersonal skills, and to be more highly valued by other members than were introverts. No significant relationship was found between temperament and the four outcome measures. Possible explanations for this finding ...

A Tagmemic Analysis of Coherence in the Writing of Descriptive Texts by College Students

A Tagmemic Analysis of Coherence in the Writing of Descriptive Texts by College Students

Date: August 1988
Creator: Kent, Carolyn E. (Carolyn Elizabeth)
Description: For this study an attempt was made to bridge the disciplines of linguistics and composition in order to examine factors contributing to textual coherence. Pairs of descriptive texts written by fifty college students were examined in order to identify the factors which differentiate quality and topic. Students were asked to compose a descriptive paragraph on the topic of fall. They were then encouraged to use their five senses, given leaves, and asked to compose a paragraph describing the leaves. The pairs of texts thus elicited were evaluated for preference by readers. The ANOVA revealed a significant difference (p=.001) between the two topics with fall texts preferred over the more specific leaves texts. Results suggest that encouraging students to use their five senses does not improve their writing. It may be more important to move through various levels of abstraction than to merely focus on sensory detail. The texts were also scored holistically by two trained evaluators. Results of this grading were used to choose five high- and five low-coherence texts on each of the two topics. These 20 texts were then analyzed in terms of the tagmemic referential hierarchy. A MANOVA was done to examine the dependent variables of Slot ...

Nonlinear Absorption Initiated Laser-Induced Damage in [Gamma]-Irradiated Fused Silica, Fluorozirconate Glass and Cubic Zirconia

Nonlinear Absorption Initiated Laser-Induced Damage in [Gamma]-Irradiated Fused Silica, Fluorozirconate Glass and Cubic Zirconia

Date: August 1988
Creator: Mansour, Nastaran
Description: The contributions of nonlinear absorption processes to laser-induced damage of three selected groups of transparent dielectrics were investigated. The studied materials were irradiated and non-irradiated fused silica, doped and undoped fluorozirconate glass and cubic zirconia stabilized with yttria. The laser-induced damage thresholds, prebreakdown transmission, and nonlinear absorption processes were studied for several specimens of each group. Experimental measurements were performed at wavelengths of 1064 nm and 532 nm using nanosecond and picosecond Nd:YAG laser pulses. In the irradiated fused silica and fluorozirconate glasses, we found that there is a correlation between the damage thresholds at wavelength λ and the linear absorption of the studied specimens at λ/2. In other words, the laser-induced breakdown is related to the probability of all possible two-photon transitions. The results are found to be in excellent agreement with a proposed two-photon-initiated electron avalanche breakdown model. In this model, the initial "seed" electrons for the formation of an avalanche are produced by two-photon excitations of E' centers and metallic impurity levels which are located within the bandgaps of irradiated Si02 and fluorozirconate glasses, respectively. Once the initial electrons are liberated in the conduction band, a highly absorbing plasma is formed by avalanche impact ionization. The resultant ...

Discrimination of Time-Compressed Speech Stimuli: a Comparison Study Using a Closed-Set Task With Older Adults

Discrimination of Time-Compressed Speech Stimuli: a Comparison Study Using a Closed-Set Task With Older Adults

Date: August 1987
Creator: Patterson, Karen Ann
Description: Use of time-compressed speech stimuli has been found to be clinically effective in differential diagnosis of lesions of the temporal lobe. However, notably absent from the literature is information concerning performance of adults on time-compressed closed-set speech discrimination tasks. The goal of this study mas to compare performance of 12 males and 12 females between age 50 and age 70 on a time-compressed closed-set speech discrimination test against the performance of 12 males and 12 females between age 10 and age 28 on the same task. The Word Intelligibility by Picture Identification test (WPI) was presented in both non-compressed and time-compressed conditions to all subjects. Previous research suggests that a difference in performance between age groups and between males and females in the older age group should be expected. Average results indicated negligible differences between age or gender groups under any of the conditions tested. Additionally, the test yielded perfect or near perfect scores for all subjects in the non-compressed condition. Lack of differentiation of results suggests that the Word Intelligibility by Picture Identification CUIPI) may be insensitive to the discrimination disorders expected in older adults, that the subjects included in the study were atypical of older adults in general ...

The Influence of Chinese Folk and Instrumental Music on Tcherepnin's "Chinese mikrokosmos": A Lecture Recital, Together with Three Recitals of Selected Works of J.S. Bach, W.A. Mozart, C. Debussy, S. Rachmaninoff, D. Shostakovich, and Others

The Influence of Chinese Folk and Instrumental Music on Tcherepnin's "Chinese mikrokosmos": A Lecture Recital, Together with Three Recitals of Selected Works of J.S. Bach, W.A. Mozart, C. Debussy, S. Rachmaninoff, D. Shostakovich, and Others

Date: August 1988
Creator: Luo, Yeou-Huey
Description: One of the most important compositional theories of Alexander Tcherepnin (1899-1977), Russian-American composer and pianist, is the Eurasian ideology, which was a result of the influence of Eastern culture. Inspired by this theory, Tcherepnin not only extricated himself from his own compositional techniques, but also intensified his search for musical folklore. In April, 1934, he began a world tour which was to include China, Japan, Singapore, the Philippines, Egypt, and Palestine, to search for "musical folklore." He became so fascinated with the culture of ancient China that he cancelled the rest of his arrangements, and, except for visits to Japan, he remained in China for three years, until the outbreak of the Sino-Japanese War in July, 1937. During his three-year stay in China, Tcherepnin was greatly attracted to Chinese culture, and as a result, Chinese culture influenced his music to a significant degree. This essay examines the manner in which Tcherepnin's music was influenced by his experiences in China. In order to precisely analyze the close affiliation between Chinese musical elements and Tcherepnin's "Chinese Mikrokosmos," many original Chinese sources proved indispensable in this study. These sources include Chinese folk music, theater music, instrumental music, religious music, and Chinese periodicals and ...

Speech Recognition Using a Synthesized Codebook

Speech Recognition Using a Synthesized Codebook

Date: August 1988
Creator: Smith, Lloyd A. (Lloyd Allen)
Description: Speech sounds generated by a simple waveform synthesizer were used to create a vector quantization codebook for use in speech recognition. Recognition was tested over the TI-20 isolated word data base using a conventional DTW matching algorithm. Input speech was band limited to 300 - 3300 Hz, then passed through the Scott Instruments Corp. Coretechs process, implemented on a VET3 speech terminal, to create the speech representation for matching. Synthesized sounds were processed in software by a VET3 signal processing emulation program. Emulation and recognition were performed on a DEC VAX 11/750. The experiments were organized in 2 series. A preliminary experiment, using no vector quantization, provided a baseline for comparison. The original codebook contained 109 vectors, all derived from 2 formant synthesized sounds. This codebook was decimated through the course of the first series of experiments, based on the number of times each vector was used in quantizing the training data for the previous experiment, in order to determine the smallest subset of vectors suitable for coding the speech data base. The second series of experiments altered several test conditions in order to evaluate the applicability of the minimal synthesized codebook to conventional codebook training. The baseline recognition rate ...

Ability Grouping in College Beginning Media Writing Classes

Ability Grouping in College Beginning Media Writing Classes

Date: December 1987
Creator: Haber, Marian Wynne
Description: The problem with which this investigation is concerned is that students of unequal writing ability are frequently placed in the same beginning media writing classes in college journalism. It is difficult for a teacher to be effective when the ability of the students ranges from those who cannot write clear complete sentences to others whose work already appears in newspapers and magazines. The purpose of this study is to determine whether students who are ability grouped into slow—average and advanced groups do the same, better, or worse than heterogeneously grouped students. In the spring semester of 1987, students in Journalism 1345, Media Writing laboratory, at the University of Texas at Arlington, were given a pretest to determine how well they wrote a simple news story and a simple feature story. On the basis of that test, which was graded by three raters, the students were placed in two separate ability groups in three classes. The fourth class contained students with heterogeneous abilities who were not placed in groups. At the end of the semester a posttest was given in news and feature writing. A two-way analysis of variance was used to analyze the posttest scores of sixty-seven students. There was ...

Knowledge and Skills for the Adult Educator in Thailand

Date: December 1987
Creator: Tamrongsin Jiearatrakul
Description: The purpose of this study was to identify and specify knowledge and skills needed by adult educators in Thailand. This study provided information for establishing a guide to be used in professional training and in graduate programs in adult education. A three round Delphi technique was used to develop the consensus of findings. The first round solicited open-ended responses from twenty panelists. One hundred and twenty-five knowledge and skill statements, the responses from the first round, were developed into a five-point rating scale questionnaire. This questionnaire was utilized in both Round II and III. Median, mode and interquartile ranges were applied to specify the consensus of the panel of experts. The one hundred and twenty-five knowledge and skill statements, seventy-five knowledge statements and fifty skill statements, were classified into four major categories: teaching, administration, research and general experience. The experts for the study consisted of eleven non-formal education officers and nine university professors in adult/continuing education and non-formal education. From seventy-five knowledge statements, sixteen were rated at the highest priority of importance. Forty-nine statements were rated at above average priority of importance and two statements were rated at average. Eight statements did not meet the interquartile range criterion as a ...

An Examination of Two Significant Percussion Compositions: Karlheinz Stockhausen's Zyklus and Ingolf Dahl's Duettino Concertante, a Lecture Recital Together with Five Recitals of Selected Works of A. Ginastera, A. Wilder, W. Kraft, and Others

Date: December 1987
Creator: Carney, Michael R. (Michael Reed), 1952-
Description: Zvklus (1959) by Karlheinz Stockhausen and Duettino Concertante (1966) by Ingolf Dahl represent two of the most significant percussion compositions that present the percussionist as soloist. The performer of these works, either unaccompanied or accompanied by a non-percussion instrument, is featured as executant, interpreter, and improvisor. They are regarded as classics in the medium of multiple percussion because of their frequency of performance and their profound effect on notation, musical composition, and the technical expectations of the percussionist. This paper examines these compositions and their historical significance to both percussion literature and the percussionist. Each of these compositions is analzyed by examining instrumentation, compositional procedures, and performance problems. Finally, the notational procedures and role of the performer in these compositions are compared. A discussion of the development of the percussion batterie, percussion ensemble, and the important early solo multiple percussion compositions provides historical perspective for these compositions. This perspective is enhanced by consideration of biography, influences, and stylistic development of each composer.

Venture Capital Investment and Protocol Analysis

Venture Capital Investment and Protocol Analysis

Date: December 1987
Creator: Pfeffer, Mary Graves
Description: This study used protocol analysis to identify key variables in the venture capital investment decision-making process. The study used a fictional business plan which was based on six actual business plans. This fictional business plan was presented to ten venture capitalists who were asked to review it to decide whether to interview the investee. The protocols obtained from these subjects were analyzed to determine patterns within the subjects' review. The sections of the business plan which were commonly reviewed first were the deal structure, the executive summary, and the management section. The management section was used by the greatest number of subjects. The market section was used the greatest number of times. The data were also organized by type of operators used in each subject's protocols. Information Search/Retrieval operators were most common, followed by Task Structuring/Set Goal operators. When classified into the four major categories of Task Structuring/Set Goal, Information Acquisition, Analytical/ Inferential, and Choice operators, Analytical/Inferential operators were used most frequently. Choice operators were least used. The phrases were analyzed by the relevant section in the business plan. The market received the greatest number of references, followed by references to the product and to management. However, when references to ...

A Study of the Responsibilities of Department Chairpersons in 5-A Public High Schools in Texas

Date: December 1987
Creator: Lawrence, Dale R. (Dale Robert)
Description: This study identified and compared the perceptions of department chairpersons and their principals about what responsibilities should be assigned to chairpersons, what responsibilities are currently assigned to chairpersons, and the chairperson' perceived need for any additional training, administrative support, departmental support, or released time in order to fulfill responsibilities currently assigned. Principals and chairpersons from 132 of the 264 5-A public high schools in Texas were surveyed by means of a 61- item questionnaire. The questionnaire included responsibilities in ten areas: planning, evaluation, budgeting, personnel, curriculum and instruction, communications, scheduling, clerical activities, supervision, and advising. Chairpersons from English, Foreign Languages, Mathematics, Physical Education, Science, and Social Studies were included in the study. Data collected in the study were keypunched and computer-processed, generating frequencies, percentages, means, and appropriate chi-square tests of independence, and probability factors for determining significance. The following conclusions were drawn from the study. 1. There is substantial agreement between Texas principals and chairpersons about responsibilities that should and should not be assigned to chairpersons in the areas of planning, budgeting, communications, and advising. 2. There is moderate to substantial disagreement . between Texas principals and chairpersons about responsibilities that should and should not be assigned in the areas ...

California-ko Ostatuak: a History of California's Basque Hotels

California-ko Ostatuak: a History of California's Basque Hotels

Date: May 1988
Creator: Echeverría, Jerónima, 1946-
Description: The history of California's Basque boardinghouses, or ostatuak, is the subject of this dissertation. To date, scholarly literature on ethnic boardinghouses is minimal and even less has been written on the Basque "hotels" of the American West. As a result, conclusions in this study rely upon interviews, census records, local directories, early maps, and newspapers. The first Basque boardinghouses in the United States appeared in California in the decade following the gold rush and tended to be outposts along travel routes used by Basque miners and sheepmen. As more Basques migrated to the United States, clusters of ostatuak sprang up in communities where Basque colonies had formed, particularly in Los Angeles and San Francisco during the late nineteenth century. In the years between 1890 and 1940, the ostatuak reached their zenith as Basques spread throughout the state and took their boardinghouses with them. This study outlines the earliest appearances of the Basque ostatuak, charts their expansion, and describes their present state of demise. The role of the ostatuak within Basque-American culture and a description of how they operated is another important aspect of this dissertation. Information from interviews supports the claim that the ostatua was the most important social institution ...

Validity of a Brief Self-Rating Visual Analogue Pain Questionnaire

Date: May 1988
Creator: Cuencas, Ramon
Description: It is believed by many researchers that little attention has been given to patients' perceptions of the impact of chronic pain on their lives. In recognition of this need, G. Frank Lawlis, C. Edward McCoy, and David K. Selby developed the Dallas Pain Questionnaire (DPQ) to assess the amount of chronic pain that affects four aspects (daily activities, work-leisure activities, anxiety-depression, and social interest) of the patients' lives. The present study, conducted to validate the DPQ's statistical properties, first reviews the literature addressing the various theories and varieties of pain, its opiates, and the two current approaches to quantify pain. This study included a total of 143 subjects. Clinical subjects were 104 inpatients in the Spinal and Chronic Pain Center at Medical Arts Hospital and 15 chronic pain outpatients released to work. Normal subjects consisted of staffing personnel (n = 13) and flight assistance employees (U = 11)- Both clinical and normal groups completed the DPQ. The Minnesota Multiphasic Personality Inventory (MMPI) was administered only to the clinical population. Results suggest that the DPQ is both externally reliable (stability reliability coefficient of .970) as well as an internally consistent instrument. Two factors emerged from factor structure analysis. Factor one (63.2% ...

Frontier Defense in Texas: 1861-1865

Frontier Defense in Texas: 1861-1865

Date: December 1987
Creator: Smith, David Paul, 1949-
Description: The Texas Ranger tradition of over twenty-five years of frontier defense influenced the methods by which Texans provided for frontier defense, 1861-1865. The elements that guarded the Texas frontier during the war combined organizational policies that characterized previous Texas military experience and held the frontier together in marked contrast to its rapid collapse at the Confederacy's end. The first attempt to guard the Indian frontier during the Civil War was by the Texas Mounted Rifles, a regiment patterned after the Rangers, who replaced the United States troops forced out of the state by the Confederates. By the spring of 1862 the Frontier Regiment, a unit funded at state expense, replaced the Texas Mounted Rifles and assumed responsibility for frontier defense during 1862 and 1863. By mid-1863 the question of frontier defense for Texas was not so clearly defined as in the war's early days. Then, the Indian threat was the only responsibility, but the magnitude of Civil War widened the scope of frontier protection. From late 1863 until the war's end, frontier defense went hand in hand with protecting frontier Texans from a foe as deadly as Indians—themselves. The massed bands of deserters, Union sympathizers, and criminals that accumulated on ...

Dispute Resolution Studies in the Institutions of Higher Learning: an Initial Investigative Study of Professors' Attitudes

Date: December 1987
Creator: Ghadrshenass, Delavar
Description: Conflict is present in all human relationships and societies. Throughout history, fighting has been more notable than peacemaking. Only recently have conflict resolution studies entered the mainstream of academia. Since peace is no longer an option, but a necessity, educators must become actively engaged in promoting the importance of peacemaking skills among their students. In 1986, the National Institute for Dispute Resolution funded a study of conflict resolution in higher education. Results disclosed a proliferation of courses but little about their quality. The present study evaluates the status of alternative dispute resolution (ADR) in the curricula of three major universities in North Texas and compares it with results from four other universities which were reported to have the heaviest concentration of ADR courses. A questionnaire was constructed to collect data in the following areas: place, significance of ADR in contemporary curricula, important factors determining attitudes toward ADR, and expectations/aspirations of faculty concerning teaching of ADR. Using a Likert scale, attitudes toward ADR were measured through regression analysis. Four of seven independent variables (age, sex, political orientation, and ADR training) were significant at jd = .05. Forty ADR-related courses were identified in seven universities. The concentration of ADR courses was management ...

A Comparison of the Transcription Techniques of Godowsky and Liszt as Exemplified in Their Transcriptions of Three Schubert Lieder

A Comparison of the Transcription Techniques of Godowsky and Liszt as Exemplified in Their Transcriptions of Three Schubert Lieder

Date: December 1987
Creator: Cloutier, David, 1948-
Description: This investigation sought to compare the transcription techniques of two pianist-composers, Godowsky and Liszt, using three Schubert lieder as examples. The lieder were "Das Wandern" from Die Schöne Müllerin, "Gute Nacht" from Winterreise, and "Liebesbotschaft" from Schwanengesang. They were compared using four criteria: tonality, counterpoint, timbral effects, and harmony. Liszt, following a practice common in the nineteenth century, was primarily concerned with bringing new music into the home of the domestic pianist. The piano transcription was the most widely used and successful medium for accomplishing this. Liszt also frequently transcribed pieces of a particular composer in order to promulgate them by featuring them in his recitals. The Schubert lieder fall into this category. Liszt did not drastically alter the original in these compositions. Indeed, in the cases of "Liebesbotschaft" and "Das Wandern," very little alteration beyond the incorporation of the melody into the piano accompaniment, occurs.Godowsky, in contrast, viewed the transcription as a vehicle for composing a new piece. He intended to improve upon the original by adding his own inspiration to it. Godowsky was particularly ingenious in adding counterpoint, often chromatic, to the original. Examples of Godowsky's use of counterpoint can be found in "Das Wandern" and "Gute Nacht." ...

Creator: Blake, Faye W.
Description: This research began with the Hill Inventory. Cognitive style preference variables were classified as one of following four types: Theoretical Codes, Qualitative Codes, Social-Cultural Codes or Reasoning Modalities. A consumer behavior perspective was then used to form an alternative structure for the Hill Inventory variables. The following three constructs were proposed: Evaluation Codes, Perceptual Codes, and Reasoning Modalities. The purpose of this research was to assess the structural form and measurement validity of the Hill Inventory. Specific steps taken to accomplish this objective included: developing confirmatory factor and structural equation models; using the LISREL software package to analyze the model specifications; and assessing the validity of the questions used to measure the variables. A descriptive research design was used to compare the model specifications. The research instrument consisted of eight statements for each of twenty-eight variables for a total of 224 questions. Five-point response choices were described by the words: often, sometimes, unsure, rarely, or never. The sample consisted of 285 student subjects in marketing classes at a large university. Data analysis began by comparing the distributions of the data to a normal case. Parameter estimates, root mean square residuals and squared multiple correlations then were obtained using the LISREL ...

A Path Analysis of a Job Burnout Model Among Firefighers

A Path Analysis of a Job Burnout Model Among Firefighers

Date: August 1988
Creator: Goza, Gail R.
Description: The purpose of this study was to propose an exploratory causal model that examines the influence of several antecedent variables on burnout. The antecedent variables included age, marital status, education, tenure, Type A personality, Jungian types, death anxiety, leadership style, job satisfaction, stress, coping efficacy, and marital satisfaction. The validity of the causal model was tested by using path analysis. Subjects were 100 male firefighters who completed self-report measures of the predictor variables. Instruments included the Jenkins Activity Survey, Myers- Briggs Type Indicator, Collett-Lester Attitudes Toward Death Scale, Leader Behavior Description Questionnaire, Job Descriptive Index, Perceived Job Stress, The Coping Inventory, Dyadic Adjustment Scale, and the Maslach Burnout Inventory. Perceived work stress made the only direct contribution to the variance in burnout. Direct paths were found to stress from job satisfaction, Type A personality, and single marital status. Job satisfaction was directly related to leadership (consideration) and the Jungian Introversion, Feeling, and Perceiving preferences. Direct paths were found to marital satisfaction from death anxiety, leadership (consideration), and leadership (structure). Leadership (consideration) was directly related to structure. From the above results, it can be concluded that perception of stress is an important factor in predicting burnout. Other factors are important contributors ...

Date: August 1988
Creator: Bunger, R. C. (Robert Charles)
Description: In this study a two-part mixed probability density function was derived which described the relative changes in the Standard and Poor's 100 Stock Index over various intervals of time. The density function is a mixture of two different halves of normal distributions. Optimal values for the standard deviations for the two halves and the mean are given. Also, a general form of the function is given which uses linear regression models to estimate the standard deviations and the means. The density functions allow stock market participants trading index options and futures contracts on the S & P 100 Stock Index to determine probabilities of success or failure of trades involving price movements of certain magnitudes in given lengths of time.

The Decline of the Country-House Poem in England: A Study in the History of Ideas

The Decline of the Country-House Poem in England: A Study in the History of Ideas

Date: August 1988
Creator: Harris, Candice R. (Candice Rae)
Description: This study discusses the evolution of the English country-house poem from its inception by Ben Jonson in "To Penshurst" to the present. It shows that in addition to stylistic and thematic borrowings primarily from Horace and Martial, traditional English values associated with the great hall and comitatus ideal helped define features of the English country-house poem, to which Jonson added the metonymical use of architecture. In the Jonsonian country-house poem, the country estate, exemplified by Penshurst, is a microcosm of the ideal English social organization characterized by interdependence, simplicity, service, hospitality, and balance between the active and contemplative life. Those poems which depart from the Jonsonian ideal are characterized by disequilibrium between the active and contemplative life, resulting in the predominance of artifice, subordination of nature, and isolation of art from the community, as exemplified by Thomas Carew's "To Saxham" and Richard Lovelace's "Amyntor's Grove." Architectural features of the English country house are examined to explain the absence of the Jonsonian country-house poem in the eighteenth century. The building tradition praised by Jonson gradually gave way to aesthetic considerations fostered by the professional architect and Palladian architecture, architectural patronage by the middle class, and change in identity of the country ...

Computer Realization of Human Music Cognition

Computer Realization of Human Music Cognition

Date: August 1988
Creator: Albright, Larry E. (Larry Eugene)
Description: This study models the human process of music cognition on the digital computer. The definition of music cognition is derived from the work in music cognition done by the researchers Carol Krumhansl and Edward Kessler, and by Mari Jones, as well as from the music theories of Heinrich Schenker. The computer implementation functions in three stages. First, it translates a musical "performance" in the form of MIDI (Musical Instrument Digital Interface) messages into LISP structures. Second, the various parameters of the performance are examined separately a la Jones's joint accent structure, quantified according to psychological findings, and adjusted to a common scale. The findings of Krumhansl and Kessler are used to evaluate the consonance of each note with respect to the key of the piece and with respect to the immediately sounding harmony. This process yields a multidimensional set of points, each of which is a cognitive evaluation of a single musical event within the context of the piece of music within which it occurred. This set of points forms a metric space in multi-dimensional Euclidean space. The third phase of the analysis maps the set of points into a topology-preserving data structure for a Schenkerian-like middleground structural analysis. This ...
