College Students' Preference of Computer Input Device: Keyboard versus Mouse

Description: In the last several years, there has been an interest in graphical user interfaces as compared with character user interfaces. The "mouse" is the device most closely associated with graphical user interfaces. Key strokes are more closely associated with character user interfaces. Given these associations, is there a preference for the keyboard or for the mouse as an input device? The determination of user preference was reduced to the determination of preference of key strokes or mouse clicks for selection of main menu items. The subjects, university students working with Microsoft Works by Microsoft Corporation, copyright 1987-1989, were learning how to use application software. While Microsoft Works was running, tracking software recorded every user key stroke and mouse click, together with data about these key strokes and mouse clicks. From the analysis of these data, common preference for the means of menu item selection was determined.

Ronald Stevenson's Passacaglia on DSCH: Understanding the Composer's Unique Approach to Large-Scaled Structure, a Lecture Recital, together with Three Recitals of Selected Works of L.V. Beethoven, J. Brahms, F. Liszt, F. Mendelssohn, B. Bartók and Others

Description: This paper investigates Ronald Stevenson's unique treatment of large-scaled structure in his Passacaglia on D S C H. This piece's unusual eighty-minute length, use of traditional forms and unusual piano techniques, musical references to other cultures and a massive triple-fugue over a ground bass will be examined as they relate to its overall form. The elements of rhythm, melody/mode, harmony, counterpoint, piano techniques, and tonality are also used as means of highlighting many unifying elements of the piece which contribute to its overall cohesiveness. Tributes to other composers, among them Dimitry Shostakovich to whom the piece is dedicated, are discussed in addition to many references to world cultures and events which support Stevenson's views on what he terms world music. Rarely is a piece written that encompasses such a wide range of musical elements that possess the ability to engage an audience for an uninterrupted length of eighty-minutes. As of yet, an in-depth scholarly investigation of Stevenson's treatment of formal unity in this landmark piano work has not been done. This analysis reveals Stevenson's approach to composing in such a large form, as well as illustrating his mastery of variation, counterpoint and unending ingenuity for innovative piano techniques. The composer's background and philosophies are discussed as well as the major impact made on his compositional style by both Percy Grainger and Ferruccio Busoni.

Non-Native Speakers of English and Denominal Regularization

Description: The purpose of this study was to determine whether nonnative speakers of English have access to specifically-linguistic constraints governing past tense morphology. Forty non-native speakers of English rated the naturalness of 29 exocentric, or headless, verbs in a partial replication of Kim, Pinker, Prince, and Prasada (1991) which looked at the same phenomenon in native speakers. Nonnative speaker performance was similar to the 40 subject native speaker control group. A correlation also existed between length of residence and subject ratings. The results imply that non-native speakers have access to the rules governing past tense morphology although not as completely as native speakers.

Effects of Meal Size and Type, and Level of Physical Activity on Perceived Masculinity, Femininity, Likability and Attractiveness

Description: Previous research indicates that women are judged on the amount of food eaten and that both men and women are judged on the type of food eaten. This study is an attempt to determine whether meal size or type predominantly accounts for these findings on the variables of masculinity, femininity, attractiveness, thinness, fitness, and likability. Physical activity was also included to determine its effect on these variable. Subjects used were 313 undergraduate students. Results indicate that meal type is more influential than meal size and that physical activity significantly influences judgements of others. The results are discussed in terms of future research and relatedness to socio-cultural theories of eating disorders.

Attenuation of Escherichia Coli Aspartate Transcarbamoylase Expressed in Pseudomonas Aeruginosa Mutant and Wild Type Strains

Description: No apparent repression of pyr gene expression in Pseudomonas aeruginosa is observed upon addition of exogenous pyrimidines to the growth medium. Upon introduction of the subcloned Escherichia coli pyrBI genes for aspartate transcarbamoylase (ATCase) into a P. aeruginosa pyrB mutant strain, repression was observed in response to exogenously fed pyrimidine compounds. The results proved that it is possible to bring about changes in pyrimidine nucleotide pool levels and changes in transcriptional regulation of gene expression as a result. Thus, the lack of regulatory control in P. aeruginosa pyr gene expression is not due to an inability to take up and incorporate pyrimidine compounds into metabolic pools, or to an inability of the RNA polymerase to respond to regulatory sequences in the DNA but is probably due to a lack of specific regulatory signals in the promoter of the genes themselves.

Characteristics of Intensive English Program Directors

Description: The purpose of this study is to discover if there exists a difference between the perceived roles and functions of intensive English program (IEP) directors and what they actually are. The study is a partial replication of Matthies (1983). A total of 46 subjects participated in a nation-wide survey which asked the respondents to rate the importance of functions and skills in good job performance and in self-assessment of ability. The findings indicated that IEP directors rate the activities associated with administration higher in importance than teaching skills, yet rate themselves better at teaching overall. Additionally, the respondents have more and higher degrees in Linguistics and Applied Linguistics than previously seen by Matthies (1983).

Effects of Perceived Quality, Product Category Similarity, and Brand Breadth on Consumers' Perceptions of Brand Extensions: Tests of Categorization Theory and Cognitive Response Theory

Description: Various constructs are related to predicting consumers' perceptions of brand extensions. Among these, three constructs, perceptions of perceived quality (PQ) associated with the parent brand, product category similarity (PCS) of an extension to its parent brand, and brand breadth (BB) of the parent, are central to many brand extension studies. The purpose of this study is to clarify the roles of these three constructs and to pit predictions from an alternative theoretical perspective — cognitive response theory — against predictions based on categorization theory.

Commitment as an Indicator of Turnover in First Line Manufacturing Supervision

Description: Organizational commitment is most commonly defined as a measure of an employee's commitment to the company or larger organization. In a longitudinal study, the Organizational Commitment Questionnaire was administered to 123 first line manufacturing supervisors in a defense contracting firm. After a one year check, subjects were grouped into categories of voluntary and involuntary turnover. The results suggest that significant relationships exist among the variables of departmental commitment, turnover and tenure. However, the study failed to show any relationship between organizational commitment and turnover.

The Kinetic Structures of Metric Temporal Patterns in Selected Beginning Piano Method Series

Description: The purpose of this study was to investigate the kinetic structures or reinforcement schedules of metric temporal patterns (metric combination of note values within a measure) in five best-selling beginning piano method series. Based upon a survey mailed to 98 music dealers, the five best-selling beginning piano method series in 1992 and 1993 were identified as: the Alfred Basic Piano Library, Bastien Piano Basics, David Carr Glover Piano Library, John. W. Schaum Piano Course, and John Thompson Modern Course for Piano. A coding system was developed for identifying the numerical appearances and occurrences of various metric temporal patterns per learning piece within each method series. Several computer programs were written to compute the kinetic structures, scope, and pacing of metric temporal patterns for each method series. The derived data were then compared to delineate relationships between the three analytical variables.

The Relationship of Adult Attachment Styles to Working Models and Behaviors in Marriage

Description: The relationship between adult attachment style and romantic relationship quality in marriage relationships was explored. Romantic relationship quality was measured at the working model (or perceptual) and the behavioral levels. No previous research had investigated romantic relationship quality as reflecting specific attachment related perceptions of self and spouse or as attachment related behaviors. Two hundred and six married subjects were recruited from university campuses, churches, and on an individual basis. Most of the subjects were white, middle class, and had children. Subjects completed self-report questionnaires measuring adult attachment style, working model of self and romantic partner, and reports of relationship behaviors of self and romantic partner. The first hypothesis proposed that attachment style differences would be seen in specific attachment related working models of self and romantic partner. The second hypothesis proposed that attachment style differences would be seen in reports of attachment related behaviors for self and romantic partner. Hypotheses were tested using multivariate analysis of variance.

Neuropsychological Functioning of Blind Subjects with Learning Disabilities Compared to Those with Blindness Alone

Description: It has been hypothesized that a disproportionate percentage of the blind population are learning disabled. In the past, norms and technology were not available to assess in a cost effective manner the blind client's neuropsychological functioning. Norms for the Wide Range Achievement Test - Revised (WRAT-R2) are now available for a blind population without any neuropsychological dysfunctioning. This study utilized the adapted WRAT-R2 and the Comprehensive Vocational Evaluation System (CVES), a neuropsychological test battery adapted for the blind, to investigate the possibility that learning disabilities are present in the adult blind population. Suspected learning disabled, blind subjects were compared with normal blind subjects. There were significant neuropsychological differences between the two groups.

Scaling Behaviors and Mechanical Properties of Polymer Gels

Description: Polymer gels undergo a volume phase transition in solvent in response to an infinitesimal environmental change. This remarkable phenomenon has resulted in many potential applications of polymer gels. The understanding of its mechanical properties has both scientific and technological importance. For this purpose, we have developed a novel method for measuring Poisson's ratio, which is one of the most important parameters determining the mechanical property of gels. Using this method, Poisson's ratio in N-isopropyacrylamide (NIPA) and polyacrylamide (PAAM) gels has been studied.

A Qualitative Study of Nine Elementary Principals Providing Inclusion for the Differently Abled

Description: This is a qualitative description of the decision making processes that nine elementary principals use in determining campus level services for the differently abled and of how their administrative styles and values impact those decisions. Both the literature on leadership and on special education inclusion are reviewed. This review creates the framework in which the research questions are examined and structures the reporting of the findings. The defining attributes of leadership styles in conjunction with the defining attributes of inclusion are the heart of this study. Audiotaped interviews with each principal provide the data related to questions of leadership style, decision making, philosophy and autonomy. Separate site visits in which teachers from both regular and special education are queried as to the actual practices on their respective campuses and to their reactions to program changes involving the differently abled students. The combination of data gathered from the principal interviews, from the site visitations and the use of triangulation of data provide the basis for the findings.

The Relationships of Text Structure and Signaling in the Foreign Language Reading of Female Junior College Students in Japan

Description: The effects of top-level text structure and signaling on the reading recall of Japanese female junior college students studying English as a foreign language were investigated in this study. One hundred thirty-two subjects were selected from a private female junior college in Tokyo. The students were divided into three groups—high, average, and low reading comprehension levels—based on the results of the Test of Reading Comprehension. The instrument used to measure students' recall ability was developed from expository passages taken from a biology textbook. The passages were rearranged to show identifiable top-level structure, collection of description, causation, problem/solution, or comparison. Each passage was divided into two versions: a with-signaling version, in which top-level structure was explicitly stated by signaling words or phrases, and a without-signaling version, where signaling words or phrases were omitted. After the students were stratified on reading comprehension, they were assigned to eight different versions of text—two of each of the four top-level text structures, one with- and one without-signaling. In the recall test, students were instructed to read the text and to remember as much as they could.

Age/Cohort Differences in Aspects of the Self-System

Description: Age/cohort differences in several aspects of the self-system were investigated utilizing a sentence completion paradigm. Eighty-eight adults over age sixty and one hundred eight adults under age forty served as subjects. Subjects were asked to complete 30 self-referent sentence stems which were pre-structured to elicit information from the self-system. Responses were subjected to a content analysis utilizing a coding system which contained concepts used by subjects in their self-representations. Contents were coded for dimensions conceptually related to Physical Health, Autonomy, Self-Evaluation, Depression, Spirituality, and Altruism. Frequencies of codings were counted and subjected to statistical analysis for performing age group comparisons.

An Examination of Strain Among Community Police Officers in Northumbria, England

Description: This paper examines some causes of strain and frustration among police officers. Previous research suggests that police officers sufferfromthe lack of communication and support from their community. The failure of communication has caused turmoil in the past between communities and their police. A possible solution is community policing. Community policing is supposed to establish communication between the public and the police. Causes of strain and frustration among the police are discussed along with the possible benefits of community policing. Research has shown that community police officers suffer less strain and frustration than their brethren. On this premise a quantitative examination a police force in Northumbria, England was conducted. The quantitative analysis focuses on two groups; community police officers and police officers not involved in community policing.

Implementation of the Middle School Concept: a Profile of Perceived Effects

Description: This study addressed the perceptions of teachers, parents, and students in a suburban middle school about the effects of implementation of the middle school concept on instruction, peer group interaction, teacher attitudes and practices, and school culture. A qualitative approach was used for this study. Interview questions were developed to determine perceptions about effects in the areas identified in the research questions. Interviews were conducted with selected teachers, parents, and students who had exposure to the school before and after planned changes were implemented. Documents were examined for evidence of perceptions in the four areas identified. In addition, an existing data set (a student survey} was examined and the same survey was administered to a more recent group of students to identify possible patterns in student perceptions.

The Risks and Effects of Outsourcing on the Information Systems Function and the Firm

Description: IS outsourcing, especially large-scale IS outsourcing, is a comparatively recent and rapidly growing IS phenomenon, but it is also an inherently risky activity. In an IS outsourcing arrangement, the outsourcing vendor accepts responsibility for IS resources and functions formerly controlled directly by the firm. This research examines IS outsourcing from two perspectives. (1) From an IS perspective, it examines the risk perceptions of IS managers of fourteen Fortune-500 firms who had recently conducted an outsourcing evaluation. (2) From a financial perspective, it examines the theoretical relationship of IS outsourcing with financial performance, and investigates the empirical effects of IS outsourcing on the firm's market value and market risk. This research views IS outsourcing as an independent variable whose effects on the firm may be measured as changes in security returns, changes in asset risk, changes in capital structure, and long-term changes in profitability. To accomplish this, it characterizes IS outsourcing as a sale-and-leaseback transaction.
