A Study of the Factors Influencing Job Satisfaction Among Texas High School Band Directors

Description: The problem with which this study was concerned was that of measuring and examining the level of job satisfaction among Texas high school band directors. The specific methodology included a quantitative comparison through confirmatory factor analysis of the factor structures of the sample of 109 Texas high school band directors and the norming population of 1460 industrial workers. There were two purposes for conducting the study. First, the relationships between an assortment of demographic variables and measured job satisfaction were examined. The second purpose was to measure the degree of fit of the Frederick Herzberg Dual-Factor Theory to the factor structure of the sample. Correlation, t ratio, and one-way analysis of variance were used to compare the demographic variables with measured job satisfaction. Confirmatory factor analysis through LISREL was used to examine and compare factor structures. Job satisfaction was measured with the Minnesota Satisfaction Questionnaire which was developed and tested through the Work Adjustment Project, Industrial Relations Center at the University of Minnesota. The twenty-item short-form retained the general reliability and validity measures of the 100-item long form. The Demographic Data Sheet is a researcher-constructed document used to gather data for use in classifying respondents by educational background, school classification, and out-of-Texas teaching experience. Respondents were also asked to indicate chronological age and number of years creditable teaching experience. Only when classified by educational background and school classification were respondents found to have significant differences in satisfaction scores. Those band directors who hold degrees in fields other than music have significantly lower satisfaction scores than those who have only music degrees. Directors from larger UIL classification schools have higher measured levels of job satisfaction than do those in smaller Texas schools. While there are strong similarities between the factor structures of the sample group and the norming population, the sample ...

An Analysis of Respiratory Mechanisms Controlling Exercise Hyperpnea During Cycle Ergometry Conducted at Selected Workloads and Pedal Frequencies

Description: Respiratory and metabolic patterns in response to variations in exercise workload (WL) and pedal frequency (RPM) were examined in 10 healthy males. Each subject performed WLs of low (L), moderate (M) and high (H) intensity, equivalent to 25%, 50% and 75% V02 m a x at 7 pedal frequencies (40, 50, 60, 70, 80, 90 and 100 RPM). ANOVA ( 3 X 7 design) indicated that WL and RPM had independent and significant effects on all respiratory and metabolic measures; i.e., the greater the WL and RPM, the higher the HR, V02, VC02, Ve, Fb, Vt, Vt/Ti, Vt/Te and Ti/TtQt and the lower the Ti and Te. However, analysis of the interaction effect revealed different response patterns for Fb, Vt, Ti, Vt/Ti, Vt/Te and Ve among the WLs. During L-WL, increases in RPM produced increases in Ve which were due to progressive increases in both Fb and Vt. However, during M-WL and H-WL, increases in RPM produced increases in Ve which were accomplished by a constant Vt and a progressive increase in Fb. My findings suggest that during low WLs, the signal for Vt is dependent on rate of contraction, while during M-WL and H-WL, the signal for Vt appears to depend on force of contraction and is independent of increasing RPM. When comparing the L-WL and M-WL, alterations in Ve, Fb, Vt/Ti and Vt/Te in relation to increases in pedal frequency were additive. However, when these two lower WLs were compared to the H-WL, the interaction between pedal frequency and Ve, Fb, Vt/Ti and Vt/Te was multiplicative. In addition, the interaction between WL and RPM on Vt and Ti was additive when comparing the M-WL and H-WL and multiplicative when these two lower WLs were compared to the H-WL. Correlation analysis indicated that for all WLs, Te was more ...

The Effects of a Computer-Assisted and Managed Learning Program on Test Outcomes in a Basic Communication Course

Description: The problem of this investigation was concerned with the effects that a computer-assisted and managed learning program had on the test outcomes of college students enrolled in a basic communication course. The purpose of the study was to determine the effects of participation in a computer-assisted and managed learning on the test outcomes of college students enrolled in a basic communication course. In order to facilitate the experiment, four hypotheses were formulated: 1. There will be significant differences in the posttest scores among the three groups. More specifically (a) the computer-assisted and managed learning (CAML) group will have significantly higher posttest scores than the teacher-assisted learning (TAL) group and the control group. 2. Computer apprehension will be significantly lower for students assigned to the CAML program, than students assigned to the TAL or control groups. 3. Computer complexity will be significantly lower for students assigned to the CAML group, than the students assigned to the TAL or control groups. 4. Computer utility will be significantly higher for students assigned to the CAML group, than students assigned to the TAL or control groups. Two experimental and one control group was used in the study. The experimental groups consisted of CAML (computer-assisted and managed learning) and TAL (teacher assisted learning). The control group was not treated with assisted instruction or practice testing. There were significant differences found among the posttest scores of the three groups. Students assigned to the CAML and TAL groups did have significantly higher posttest scores than students assigned to the control group. Although there were observable differences in the posttest scores between CAML and TAL, the differences were not statistically significant. Computer apprehension was significantly lower for the CAML group than the TAL or Control groups. Computer complexity was significantly lower for CAML than the TAL or Control ...

The Role of a Developmental Screening in Kindergarten - First Grade Placement

Description: The purposes of this study were to determine if a kindergartener's developmental stage correlates with subsequent scholastic achievement, to determine whether developmentally younger children who repeat kindergarten attain higher academic achievement than developmental 1y younger children who do not repeat kindergarten, and to investigate the relationship between head circumference, developmental age, and achievement. Ninety-seven kindergartners of various ethnicity and socio-economic status were administered the Gesell School Readiness Screening Test to determine developmental age and were followed academically for three years. Head circumference was noted periodically to measure brain growth. The hypotheses predicted significant positive correlations between developmental age in kindergarten and scores on later achievement tests. Further, it was predicted that children below 5.3 years in developmental age who delayed entrance to first grade would score significantly higher on first grade achievement tests than match-paired promoted students. It was hypothesized that there would be significant correlations between head circumference growth and (a) gains in achievement test scores and (b) developmental age at kindergarten. The first hypothesis, tested by Pearson Product Moment Correlations, established the existence of significant correlations between developmental ages of test subjects and their scores on four academic achievement tests. The results indicated that developmental age was a better predictor of achievement test scores than chronological age. Since only five children in this study were retained in kindergarten, hypothesis 2 was analyzed descriptively. Mean scores on first grade achievement tests were higher for the retainees than for the "at risk" non-retainees. Hypothesis 3 was tested by stepwise multiple regression. At the first step, the linear trend between the independent variable, CTBS score, and the dependent variable, I TBS score, was calculated and found to be significant at the .001 level. The addition of head circumference growth to the equation did not add significantly to the prediction of I ...

Texas Public School District Legal Costs and Preventive Law Practices

Description: The purpose of this study was to compare the legal costs of Texas public school districts during the school years 1980-81, 1981-82, and 1982-83 with the preventive law practices utilized by those districts. A survey was made of Texas superintendents' knowledge of school law. The data were contrasted with legal costs and the preventive law practices of the district. Two survey instruments were developed, and the case study approach was utilized. A survey was sent to the 1,101 Texas public school superintendents. The twenty-five item instrument was designed to solicit information regarding the amount of money spent by districts and the types of preventive law practices that school districts use to reduce legal costs. A legal awareness questionnaire was developed and administered to 72 of the 542 superintendents who responded to the first survey instrument. Three school districts were selected to be case study sites. The data from the instruments were analyzed to determine if a relationship existed between a district's legal costs and its preventive law practices, a district's legal costs and the superintendent's knowledge of school law, and a superintendent's knowledge of school law and the district's preventive law practices. The major conclusions of the study were as follows: (1) The larger the school district, the more money the district spends on legal costs. (2) Districts that incorporate preventive law activities do not necessarily have lower legal costs. (3) The differences in legal costs of a district and the types of preventive law activities utilized by the district are generally associated with district size, rather than with the absence of presence of the specific preventive law activity. (4) The legal knowledge possessed by the superintendent does not have an impact on the legal costs of the district. (5) The superintendent's knowledge of school law does not affect the ...

On Parent-Child Relations: Toward the Construction of a Theory of Filial Exchange

Description: This investigation represents an initial attempt toward the construction of a general life cycle theory of parent-child relations. Emphasis was placed on the parent-adult child relationship with the onset of a filial crisis, e.g., due to illness. After the theory was described, two of the five propositions comprising this orientation (i.e., propositions four and five) were analyzed through a series of twenty-five hypotheses. The objectives of these hypotheses were (a) to analyze the relationship between the length of time involved in various patterns of filial responsibility and the likelihood that these patterns will become institutionalized as obligatory roles and (b) to determine how factors associated with these emergnt role obligations contribute to the cost of caregiving. A probability sample of 180 caregivers was obtained from within the Dallas/Ft. Worth area. Multiple and partial correlation analyses and the use of Student's t revealed that the length of time involved as a caregiver was significantly related to the number of informal caregiving roles performed by adult children. In addition, results indicated that the length of involvement in each caregiving role examined (i.e., household care, transportation service, personal care, medical attention, meal preparation, financial management and mobility assistance) was significantly related to (a) the frequency of providing these services to an aged parent and (b) the level of responsibility in each service area except financial management (which tended to remain constant over time)• An adult child s level of obligation to ensure that caregiving services were provided was also significantly associated with the length of caregiving involvement. Furthermore, this study found tentative support for the contention that the social-psychological cost of providing care for a dependent parent was associated with (a) the frequency of providing transportation services and medical attention, (b) the number of informal caregiving activities performed and (c) the length of ...

Absorption, Relaxation, and Imagery Instruction Effects on Thermal Imagery Experience and Finger Temperature

Description: A skill instruction technique based on cognitive behavioral principles was applied to thermal imagery to determine if it could enhance either subjective or physiological responsiveness. The effects of imagery instruction were compared with the effects of muscle relaxation on imagery vividness, thermal imagery involvement, and the finger temperature response. The subjects were 39 male and 29 female volunteers from a minimum security federal prison. The personality characteristic of absorption was used as a classification variable to control for individual differences. It was hypothesized that high absorption individuals would reveal higher levels of imagery vividness, involvement, and finger temperature change; that imagery skill instruction and muscle relaxation would be more effective than a control condition; and that the low absorption group would derive the greatest benefit from the imagery task instruction condition. None of the hypotheses was supported. Finger temperature increased over time during the experimental procedure but remained stable during thermal imagery. The results suggest that nonspecific relaxation effects may best account for finger temperature increases during thermal imagery. Results were discussed in relation to cognitive-behavioral theory and the characteristic of absorption.

An Analysis of the Current Texas School Finance System to Determine to What Extent it Meets Criteria for Equity Concerning School Finances

Description: The main purpose of this study was to determine the effect of Texas House Bill 72 on equalization of finances in the public school districts of Texas. House Bill 72 is a finance reform bill which was passed by the Texas Legislature during the Summer of 1984. This study involves basically three steps. First, current criteria for equity as defined by school finance "experts" and recent definitive court decisions were determined. Second, financial data from the Texas Education Agency were statistically analyzed for the 1984-1985 school year. Third, the statistical analysis was used to determine if the current Texas school finance plan meets the current criteria for equity. The population used in the study was 1,068 school districts. Based on the findings of this study the following conclusions were drawn. 1. The use of a per capita flat grant by the Texas Public School Finance System contributes to the unequalizing of financial resources available to school districts. 2. School districts with greater property index values are required to exercise very little effort toward the support of their public schools. 3. School districts with high property index values tend to have lower effective tax rates and high per-pupil expenditures. 4. School districts of least wealth exercised substantially more local tax effort in support of educational programs in their schools than more wealthy school districts. 5. School districts with low property index values are almost entirely dependent upon the Foundation School Program monies to provide the educational opportunities available within the school district. 6. The disparities in local tax effort, per-pupil expenditures, and revenues are attributable primarily to the school district's heavy reliance on local property wealth. 7. A completely perfect system of equalization would be full state funding with monies distributed to districts on an educational needs basis.

An Empirical Examination of the Effects of FASB Statement No. 52 on Security Returns and Reported Earnings of U.S.-Based Multinational Corporations

Description: Prior to the issuance of Financial Accounting Standards Board Statement No. 8 (SFAS No. 8), there was a marked inconsistency in the area of accounting for foreign currency translation. Though designed to make the diverse accounting practices of multinational corporations (MNCs) more compatible, SFAS No. 8 was the subject of a great deal of criticism, eventually leading to the issuance of Financial Accounting Standards Board Statement No. 52 (SFAS No. 52). SFAS No. 52 differs from SFAS No. 8 on objectives and method of translation, and on accounting treatments of translation adjustments. This dissertation provides an empirical examination of the security market reaction to the accounting policy change embodied in SFAS No. 52, and its impact on the volatility of reported earnings of MNCs. The effects of the issuance and early adoption of SFAS No. 52 on security return distributions were determined by both cross-sectional comparisons of cumulative average residuals (CAR) between MNCs and domestic firms and between early and late adopters, and by time-series tests on CAR of MNCs. Two volume analyses were performed to test the effects of SFAS No. 52 on security volume. The first analysis was adjusted to remove the effects of the marketwide factors on volume, and the second analysis was unadjusted for the market influences. Four nonparametric tests were used in testing the effects of SFAS No. 52 vis-a-vis SFAS No. 8 on the volatility of reported earnings of MNCs. The findings of this study led to the following conclusions: (1) SFAS No. 52 had significantly affected security returns of MNCs, but had no significant effects on security volume of MNCs; (2) the early adoption of SFAS No. 52 had no effects on security returns and volume of early adopters as opposed to late adopters; and (3) SFAS No. 52 did not have any ...

A Study of Faculty Participation In and Approval of Professional Growth and Renewal Activities in the Dallas County Community College District

Description: The purpose of this study was to determine faculty participation in and approval of professional growth and renewal activities in the Dallas County Community College District. The population consisted of 526 full-time faculty employed by the district. The DCCCD Survey instrument, which was used in the study, included activities grouped into seven categories: career development, leaves, international activities, instructional renewal, grants, reward, and a miscellaneous category. Faculty members identified participation in activities; they also identified their approval or disapproval of all activities on a five point Likert-type scale. The population was grouped by teaching field, age, years-of-experience and campus for statistical analyses. A Chi-square test of goodness of fit was conducted to determine if significant differences existed between expected and observed participation among groups in each of the seven categories. An analysis of variance was completed to determine significant differences of opinion. The findings of the study indicated significant differences between expected and observed participation in the following categories: international and instructional activities when faculty were grouped by teaching fields; reward activities among years-of-experience groups. Significant differences of opinion were reported in all but the miscellaneous category when faculty were grouped by teaching field. Other significant differences were reported in career development among age groups, in leaves and grants among years-of-experience groups and in career development, reward and the miscellaneous category among campus groups. Based on the findings in the study, the following recommendations were made. The career development program should be broadened to appeal to faculty. Leaves and travel funds must be provided for faculty. International and instructional activities must be expanded to include appropriate activities for all teaching fields. Further study should be conducted in specific areas of professional growth to determine if these activities influence the effectiveness of faculty.

Independent Quadtrees

Description: This dissertation deals with the problem of manipulating and storing an image using quadtrees. A quadtree is a tree in which each node has four ordered children or is a leaf. It can be used to represent an image via hierarchical decomposition. The image is broken into four regions. A region can be a solid color (homogeneous) or a mixture of colors (heterogeneous). If a region is heterogeneous it is broken into four subregions, and the process continues recursively until all subregions are homogeneous. The traditional quadtree suffers from dependence on the underlying grid. The grid coordinate system is implicit, and therefore fixed. The fixed coordinate system implies a rigid tree. A rigid tree cannot be translated, scaled, or rotated. Instead, a new tree must be built which is the result of one of these transformations. This dissertation introduces the independent quadtree. The independent quadtree is free of any underlying coordinate system. The tree is no longer rigid and can be easily translated, scaled, or rotated. Algorithms to perform these operations axe presented. The translation and rotation algorithms take constant time. The scaling algorithm has linear time in the number nodes in the tree. The disadvantage of independent quadtrees is the longer generation and display time. This dissertation also introduces an alternate method of hierarchical decomposition. This new method finds the largest homogeneous block with respect to the corners of the image. This block defines the division point for the decomposition. If the size of the block is below some cutoff point, it is deemed to be to small to make the overhead worthwhile and the traditional method is used instead. This new method is compared to the traditional method on randomly generated rectangles, triangles, and circles. The new method is shown to use significantly less space for all three ...

School Administrators' and Teachers' Perceptions of the Teacher Evaluation System in the State of Anambra, Nigeria

Description: The problem with which this study is concerned is the teacher evaluation system in the state of Anambra, Nigeria. The purposes of this study are (a) to provide objective information concerning the perceptions of school administrators and teachers toward the teacher evaluation system in the State of Anambra, Nigeria, (b) to determine whether agreements or differences exist between teachers' and administrators' perceptions of the teacher evaluation system, and (c) to draw conclusions and make recommendations for improvements based on the perceptions of the teachers and administrators. To accomplish these purposes, questionnaires were distributed to a random sample of 652 administrators and teachers who are currently employed in 37 randomly selected primary and secondary schools in the State of Anambra, Nigeria. Four hundred and sixty school administrators and teachers, representing 70.6 percent of the sample, returned completed usable questionnaires. Part I of the questionnaire was designed to gather relevant demographic data to determine the perceptions of the school administrators and teachers. Part II of the questionnaire contains the components of the evaluation system which were used to measure the perceptions of school administrators and teachers. Analysis of variance was used to test the data according to the independent variables. Three statistically significant differences were found among the data. (a) The primary and secondary school administrators differed significantly in their perceptions of the teacher evaluation system in the State of Anambra. This difference is ascribed to their positions which are based on their educational levels. (b) The demographic variable sex has significant effect on the perceptions of primary and secondary school teachers and administrators towards the teacher evaluation system in the State of Anambra, Nigeria. (c) The demographic variable years of professional experience appears to have a significant impact on the perceptions of the primary and secondary school teachers and administrators toward ...

Market Reactions to Accounting Policy Deliberations the Case of Pensions (SFAS No. 87)

Description: This study had two basic objectives. The first was to determine the stock market reactions to the pension policy deliberations. The second was to further our understanding of the significance of the FASB's due process. The author selected 13 critical events that preceded passage of SFAS No. 87 and designed a quasi experiment to examine the stock market reaction around the above events. Two portfolios were constructed to test the hypotheses. The first portfolio consisted of firms in the experimental group (firms sponsoring a defined benefit pension plan) and the second portfolio consisted of firms in the control group (firms sponsoring a defined contribution pension plan). The two portfolios were matched on the basis of SIC code, debt to equity ratio and assets.

The Missae De Beata Virgine C. 1500-1520: A Study of Transformation From Monophonic to Polyphonic Modality

Description: While musical sources and documents from throughout the Middle Ages reveal that mode was an enduring and consciously derived trait of monophonic chant, modality in later polyphony shares neither the historical span nor the theoretical clarity of its monophonic counterpart. Modern theorists are left with little more than circumstantial evidence of the early development of modality in polyphony. This study attempts to shed light on the problem by detailed analysis of a select body of paraphrase masses from the early sixteenth century. First, it correlates the correspondence between the paraphrased voice and the original chant, establishing points of observation that become the basis of melodic analysis. Then, these points are correlated with known rules of counterpoint. Exceptions are identified and examined for their potential to place emphasis on individual mode-defining pitches. A set of tools is derived for quantifying the relative strength of cadential actions. Levels of cadence are defined, ranging from full, structural cadences to surfacelevel accentuations of individual pitches by sixth-to-octave dyadic motions. These cadence levels are traced through the Missae de beata virqine repertoire from c. 1500-1520, a repertoire that includes masses of Josquin, Brumel, La Rue, Isaac, and Rener. While the Credos, based on two chant sources—one early (11th century) and one later (15th century)—showed little modal consistency, the Kyries show some suggestion of purposeful modal expression; and the Glorias show even greater implications. Results of the study have potential application in sixteenth-century music scholarship to such important issues as musica ficta, performance practice, text underlay, and form.

The Influence of Self-Monitoring on Return Rate Following Intake at a Child Guidance Clinic

Description: Research has yet to identify any characteristics of clients, therapists, or treatment dyads which consistently identify those clients most likely to drop out of treatment. A frame of reference which may prove useful in identifying such clients is the social psychological construct of selfmonitoring. This theory proposes that individuals involved in any social encounter differ from each other in their approach to constructing a relevant self-presentation. High self-monitors emphasize matching their behavior to situational cues while low self-monitors match their behavior to perceived internal values and traits. The present study demonstrates the effects that selfmonitoring styles of therapists and clients have on the effectiveness of a therapeutic intake interview and the client's decision whether or not to return for treatment. Additionally examined are the effects of therapist selfmonitoring style on theoretical orientations toward psychotherapy. The hypothesis that pairings of high self-monitors would be most effective is tested by Chi-square and found to be nonsignificant. Using the Chi-square test, low self-monitoring therapists are found to endorse a single approach to therapy and to strongly endorse the psychoanalytical orientation. Low self-monitors are found to be eclectic in approach. Satisfaction with the interview is examined using ANOVA. Results are nonsignificant with the exception that low self-monitoring therapists are more satisfied with the intake interview than are high selfmonitoring therapists. Finally, within-cell Pearson correlations are examined to measure agreement about satisfaction between therapist and client. Pairs of high self-monitors show the highest rate of agreement. Implications for further research in this area are discussed.

International Political Economy of External Economic Dependence and Foreign Investment Policy Outputs as a Component of National Development Strategy: Nigeria 1954-1980

Description: This study examined the effects and expectations of external economic dependence on foreign investment policy outputs with particular reference to the Nigerian experience between 1954 and 1980. Three basic kinds of external economic dependence were studied: foreign investment, the penetration of the Nigerian economy by foreign capital through the agency of the multinational corporations (MNCs); foreign trade, a measure of the Nigerian economy's participation in the world market; and foreign aid (loans and grants), a measure of Nigeria's reliance on financial assistance from governments and international financial inst itutions. For the most part, the level of Nigeria's economic dependence was very high. However, economic dependency is not translated into changes in foreign investment policy in favor of the foreign investors in Nigeria as is predicted by the dependency paradigm. The Nigerian case casts doubt on the dependency paradigm as a framework for fully explaining factors that may determine foreign direct investment policy changes that occur in a less developed Third World country. In other words, the dependency paradigm has a limited explanatory power; there is a factor independent of the economic factor operating out of the control of global capitalism (the center of the center in alliance with the center of the periphery); and that factor is the political process in Nigeria. The web of the Nigerian political process involves the various aspects of its internal functioning such as the manner in which needs, interests and demands are conveyed from the individuals and groups in the country to those performing state duties. Thus, Nigerian policy makers were more influenced by those elements than pure economic considerations treated in isolation.

New Descriptions, Intraspecific Variation and Systematic Importance of Drumming Behavior in Selected North American Plecoptera

Description: Drumming behavior is described for the first time in 33 North American Plecoptera species, and signals of an additional five species, Pteronarcys pictetii, Acroneuria abnormis, Paragnetina media, Clioperla clio and Isogenoides zionensis, are further detailed. An out-group comparison of behavioral characters in all 104 world species whose drumming is known showed that the behavior is more advanced in the Arctoperlaria Group Systellognatha than in the Group Euholognatha. In general, tapping, monophasy, touching, sequenced exchange and less than 50 taps/answer are ancestral states, and rubbing, grouping, phasing, tremulation, interspersed exchange and equal or more than 50 taps/answer are derived states. There has been some co-evolution between abdominal structure and drumming behavior. Scanning Electron Micrographs of 30 species showed that the primitive state of tapping is ascociated with three classes of abdominal structure: (1) absence of derived structures, (2) lobes or vesicles, and (3) hammers. The derived behavior of rubbing, however, occurs only in species with derived structures, and is predominant in species having vesicles and hammers. Drumming can be used as a line of evidence to aid in defining genera and species, since the behavior has a variable degree of specificity or exclusiveness in all species, particularly in groups of species I have studied in the genera Isoperla, Pteronarcys and Taeniopteryx. Typical and variant computer-synthesized male calls of three stonefly species were tested with live females. They responded at high levels in such a way that the important informational content conveyed was identified as: (1) a minimal threshold of beat numbers, and (2) a discriminant window of beat intervals. Rub frequency and bibeat calling were critical informational parameters in two species.

The Effect of Using Class Discussion as a Pre-Writing Activity in Teaching Composition to ESL Students

Description: This study examines the effect of class discussion as a pre-writing activity on actual writing performance. The experiment was conducted with all the Level 3 and Level 4 students enrolled in the Intensive English Language Institute of North Texas State University in the Spring, 1986 semester. Cochrans C test was performed to test significant differences between groups at the beginning of this test. Multivariate analysis of variance tests were used to determine the treatment effect between and within groups, and a matched t-test was also utilized to analyze the difference within tests. Pearson product moment correlation coefficient was calculated to determine the relationship between the discussion activity score and the actual writing score. Analysis of covariance tests were used to determine which variance of discussion activities had greater effect on the actual writing score.

The Relationship of Sex and Age at Entrance to School to Second Grade Achievement

Description: This investigation compared achievement of boys and girls in second grade who were seven years old in June, July, and August of 1983 to the boys and girls in second grade who were eight years old in September, October, and November of 1983. The students were tested using the Iowa Test of Basic Skills using the following areas: reading, total math, and composite scores. The study also looked at the correlation of sex and age of students who had been retained in first grade. A comparison of teacher grades to standardized test scores and ability grouping was also presented. One way analysis of variance was applied to the test results. A chi square test of independence was conducted on students retained in the first grade to determine if interaction between sex and age was indicated. Older children scored higher in all three areas measured, while girls scored higher in reading. This may seem contradictory, but is not. Age was significant beyond the .05 level, while sex was significant beyond the .001 level. This difference is explained by the extremes in means for younger boys and older girls. Since first grade curriculum emphasizes reading, this gave girls a definite advantage over boys. Boys, however, scored significantly higher in math. The results indicate a need for restructuring curriculum to meet the needs of boys and girls. Younger boys in second grade scored the lowest in all areas tested, except math. These scores would have been even more significant if the boys who were not promoted to second grade could have been included in the second grade testing. These findings indicate that total developmental age is the most important factor when considering admission for school. A closer look should be taken at the requirements for school entrance. The factors that must be considered ...

Assessing the Impact of the MAXHELP Microcomputer Orientation Course on Administrator, Teacher and Non-Educator Concerns Relating to Microcomputer Acceptance

Description: The problem this descriptive study dealt with was the fear (computerphobia) administrators, teachers, and noneducators have concerning the acceptance of microcomputers in the educational setting. The MAXHELP Project is an Air University sponsored program to assist the local schools in scientific and technological education. The 12 hour MAXHELP Microcomputer Orientation Course has graduated over 500 educators from seven Alabama school districts. This study used the Stages of Concern Questionnaire (SoCQ). This instrument was developed at the Inter-Institutional Program for the Reasearch and Development Center for Teacher Education, The University of Texas at Austin, by Hall, George and Rutherford. The SoCQ was mailed to a random sample of 300 MAXHELP graduates. A total of 212 responses were used in the study. This report concludes that the administrator and teacher groups are moving through the stages of concern when compared with the typical "non-user." Teachers show greater concerns relating to Management and administrators have greater concerns on Consequence, Collaboration, and Refocusing. Administrators are not users of microcomputers in the classroom, but are very concerned about how to facilitate the spread of microcomputers throughout the school curriculum. In general, the data indicate more similarity of teaching concerns by age, years teaching experience, and area of specialization. Concerns relating to the demands of microcomputers upon the individual who has to use microcomputers in the classroom cannot be satisfied without the microcomputer being available. Personal stage concerns will probably remain high until more microcomputers are available in the classroom. Teachers who have been in the classroom between one to six years appear to be the most prone to resist change. Special attention needs to be given to this group to demonstrate the advantages of the microcomputer as a teaching tool and as an administrative aid at both the pre-service and in-service levels.

Analysis of Human Transfer RNA Gene Heteroclusters

Description: Two phage lambda clones encompassing human tRNA genes have been isolated from a human gene library harbored in bacteriophage lambda Charon-UA. One of the clones (designated as hLeuU) containing a 20-kb human DNA fragment was isolated and found to contain a cluster of four tRNA genes. An 8.2-kb Hindlll fragment encompassing the four tRNA genes was isolated from the 20-kb fragment and subcloned into pBR322 for restriction mapping and DNA sequence analysis. The four tRNA genes are arranged as two tandem pairs with the first pair containing a proline tRNAAGQ gene and a leucine tRNAAAQ gene and the second pair containing another proline tRNAAGG gene and a threonine tRNAuQU gene. The two pairs are separated about 3 kb from each other, and the leucine tRNAAAG gene is of opposite polarity from the other three tRNA genes. The tRNA transcription units were sequenced by a unidirectional deletion dideoxyribonucleotide chain-termination method in the M13mpl8 and 19 vectors. The coding regions of the four tRNA genes contain characteristic internal split promoter sequences and do not encode intervening sequences nor the CCA trinucleotide found in mature tRNAs. The proline t R N A A G G gene is separated from the leucine t R N A A A Q gene by a 725-bp intergenic region and the second proline t R N A A G Q is 315 bp downstream of the threonine t R N A U G U gene. The coding sequences of the two proline tRNA genes are identical. The 3'-flanking regions near the 3*-ends of these four tRNA genes have typical RNA polymerase III termination sites of at least four c o n s e c u t i v e T nt. There is no homology between the 5'-flanking regions of these genes. All four tRNA genes are potentially ...
