The Achievement of Student Development Tasks by Male College Scholarship Athletes and Non-Athletes: A Comparison

Description: The problem with which this study is concerned is to determine whether or not differences exist in the achievement of student development tasks by college student athletes and non-athletes. The investigation also tested for differences in the achievement of developmental tasks between athletes and non-athletes based on the variables of race (black or white), classification, and interpersonal behavior orientation. The sample was composed of 276 male students (201 non-athletes and 75 athletes) who attend a large private university in Texas. Each participant completed both a student developmental task inventory questionnaire, which measures individual achievement of the tasks of developing autonomy, purpose, and mature interpersonal relationships, and an interpersonal relationship orientation-behavior instrument, which measures an individual's orientation to others on the scales of inclusion, control, and affection.

L-asparaginase II Production by Escherichia coli

Description: Growth of Escherichia coli A-l under aerobic conditions in an enriched medium with a total amount of 0.2 per cent glucose was biphasic and asparaginase II activity was detected after depletion of ammonia from the growth medium in the second phase of growth. Glucose was exhausted two hours before ammonia and three hours before asparaginase II activity was detected. The concentration of 3',5'-cyclic adenosine monophosphate was found to fluctuate when the dissolved oxygen in the medium reached a low level, when glucose and ammonia were exhausted, and when the cells entered the second stationary phase of growth. Culture tube studies of the growth of E_j_ coli A-l in three per cent nutrient broth with varied concentrations of ammonium chloride and potassium nitrate gave lower specific activity of asparaginase II when this was compared to that seen in three per cent nutrient broth alone. The addition of glucose to the same medium before asparaginase II activity was detected resulted in the production of acid by E. coli A-l with cessation of growth; however, addition after L-asparaginase synthesis had started did not affect the specific activity of the enzyme. The addition of ammonium chloride suppressed L-asparaginase synthesis, but addition after enzyme synthesis started had no affect. These findings suggest that asparaginase II is produced by E. coli A-l in response to low concentrations of ammonia and that exogenously supplied nitrogen compounds may play a major role in the regulation of this enzyme. It is suggested that E. coli A-l produced L-asparaginase in order to obtain ammonia for the synthesis of glutamine from glutamate. The synthesis of glutamine from glutamate is the first step of a highly branched pathway which ultimately leads to the synthesis of many of the important macromolecules of the cell.

Brain Activity in Rats Exposed to Short-Term External Electrical Fields

Description: The effects of external electric fields (EEF) on brain activity in anesthetized rats were studied. The field strengths used, 9 kV/m and 5 kV/m, both D.C. and A.C. (60Hz) were in the range of those measured beneath current overhead transmission lines. Brain activity was monitored from surface electrodes and from electrodes stereotaxically implanted in the posterior-lateral portion of the hypothalamus. It was found that 9 kV/m and 5 kV/m EEF's both D.C. and A.C. brought about statistically significant changes in hypothalamic activity, however, the effects were bi-directional, (i.e. increases and decreases). Only seven of the 60 animals exposed showed changes in the EEG recorded with surface electrodes. The data clearly indicate that (1) anesthetized animals do respond to a change in the external electric field around them, (2) the hypothalamus may contain special electro-receptors that, in turn, may alter various other physiological processes, and (3) the data indicates the need for further research to help government agencies to establish more adequate safety guidelines.

Characteristics and Predictors of Success at Two Coed Halfway Houses

Description: The present study evaluated offender characteristics associated with completion of halfway house placement by the inclusion of additional offender characteristics for analysis in addition to those studied in previous research, the analysis of a large number of representative cases, and the use of statistics allowing clear conclusions upon which to base decision making. Data analysis was done in three steps. The first Step was to identify offender characteristics which were associated with completion in halfway house placement. The second step was to see how accurate the offender characteristics identified were in predicting completion of an offender's halfway house stay. The third step was to identify any possible factors which underlie the offender characteristics identified. Discriminant analyses identified ten offender characteristics which were associated with completion of halfway house placement for 521 male offenders and four offender characteristics which were associated with halfway house completion for the group of 33 female offenders studied. These offender characteristics resulted in 75.38 percent correctly classified cases for the male offender group and 96.9 7 percent correctly classified cases for the group of female offenders. Factor analyses resulted in the identification of four factors for the group of male offenders and two factors for the female offender group. Suggestions for future research included replications of the present study leading to the identification of offender groups based on probabilities of successful halfway house completion, and the establishment of halfway house programs tailored to offenders identified as having high or low probabilities of completion.

Cindy's feller: an adaptation of Cinderella

Description: The problem with which this thesis is concerned is that of writing and directing an adaptation of the classic fairy tale, Cinderella. This study is a culmination of research on children's theatre, and the writing and producing of children's plays. The research led to the writing of the first draft of Cindy's Feller, an adaptation of Cinderella, beginning with a scenario which utilized a country-western theme. Upon completion of the first draft, the play was produced at North Texas State University during the summer of 1981. Stage directions of the play, a director's log of daily rehearsals, and an evaluation of the final productions were recorded to provide a stimulus for the writing of a final draft of Cindy's Feller and the preparation of this thesis.

A Comparison of Physics Enrollments in Selected Large Texas Secondary Schools

Description: The problem of this study is twofold. The first is to discover in what ways are physics teachers and counselors in large Texas public secondary schools encouraging students to take physics, and second, what are their perceptions of reasons for student avoidance of physics. The population consisted of physics teachers and counselors in large (1,310 minimum enrollment) high and low percentage physics enrollment schools. Percentage enrollment in physics is defined as the number of students enrolled in physics compared to total twelfth grade enrollment. Thirty high (above 8.9) and thirty low (below 8.0) percentage enrollment schools comprise the sample population. Data were collected using separate questionnaires that related to (a) school, (b) physics teacher, and (c) counselor variables that could affect physics enrollments. The questionnaires addressed to perceptions of both physics teachers and counselors covered (a) the exchange of physics course information between students, teachers, and counselors, (b) the method of exchange of physics course information, and (c) the extent to which the physics program is sold to the student body. Also elicited were eleven responses from both physics teachers and counselors that pertain to perceived reasons for student avoidance of physics courses. A statistical analysis was made between physics teachers and counselors perceptions pairing high and low percentage enrollment groups by chi square analysis of each item of the questionnaire, using a .05 level for significance.

A Comparison of the Effectiveness of Childbirth Preparatory Techniques

Description: Stress reduction techniques have been used to assist people in coping with stressful medical procedures and events. Labor and delivery training classes have utilized techniques to assist women with the childbirth process. The classes generally included basic education of labor and delivery, respiration behavior, relaxation of muscles, and participation of a coach. Reducing the amount of pain experienced in labor and delivery has been suggested for facilitating the process and decreasing the amount of medication received. The painful experience changed from an uncontrollable situation into a positive one, allowing women to feel more resourceful, less anxious, and less threatened.

A Comparison of Three Methods of Detecting Test Item Bias

Description: This study compared three methods of detecting test item bias, the chi-square approach, the transformed item difficulties approach, and the Linn-Harnish three-parameter item response approach which is the only Item Response Theory (IRT) method that can be utilized with minority samples relatively small in size. The items on two tests which measured writing and reading skills were examined for evidence of sex and ethnic bias. Eight sets of samples, four from each test, were randomly selected from the population (N=7287) of sixth, seventh, and eighth grade students enrolled in a large, urban school district in the southwestern United States. Each set of samples, male/female, White/Hispanic, White/Black, and White/White, contained 800 examinees in the majority group and 200 in the minority group. In an attempt to control differences in ability that may have existed between the various population groups, examinees with scores greater or less than two standard deviations from their group's mean were eliminated. Ethnic samples contained equal numbers of each sex. The White/White sets of samples were utilized to provide baseline bias estimates because the tests could not logically be biased against these groups. Bias indices were then calculated for each set of samples with each of the three methods. Findings of this study indicate that the percent agreement between the Linn-Harnish IRT method and the chisquare and transformed difficulties methods is similar to that found in previous studies comparing the latter approaches with other IRT methods requiring large minority samples. Therefore, it appears that the Linn-Harnish IRT approach can be used in lieu of other more restrictive IRT methods. Ethnic bias appears to exist in the two tests as measured by the large mean bias indices for the White/Hispanic and White/Black samples. Little sex bias was found as evidenced by the low mean bias indices of the male/ ...

The Decision-Making Process in Commercial Motor Carrier Selection

Description: This study is designed to gain a better understanding of the decision process of freight shippers who use commercial truckers. Pursuant to this study, it is possible to gather some insights into the phenomenon of the selection of a trucking company to transport goods. Planning is essential to the attainment of goals in any type of firm, and that is especially true in the volatile environment of commercial trucking. Development of the external environment of trucking is prerequisite to the planning process and essential to the attainment of goals. The external environment of a trucking firm is generally represented by economic, social, and political influences, which extend specifically to the nature and tendencies of its markets, i.e., the shippers.

The Development and Evaluation of a Forecasting System that Incorporates ARIMA Modeling with Autoregression and Exponential Smoothing

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

Discriminative Stimulus Properties of Cocaine: Tolerance and Cross-Tolerance Characteristics

Description: Rats were trained to discriminate an injection of cocaine, 5.0 mg/kg, from an injection of saline, using a two-lever choice paradigm: one lever was correct after cocaine injection, the other lever was correct after a saline injection. After training, cocaine and methamphetamine were generalized to the cocaine lever, but phenethylamine (PEA) was only partially generalized. Cocaine was injected every 8 hrs, 20.0 mg/kg, and the discriminability of 5.0 mg/kg was tested every other day. Redetermination of the cocaine generalization curve after 6 days of chronic administration showed a shift to the right, from an ED50 of 4.1 mg/kg in the pre-chronic condition to 10.0 mg/kg. Tolerance did not develop to the behavioral effects of cocaine, measured by time to the first reinforcement and response rate. There was cross-tolerance to methamphetamine; however, no evidence for cross-tolerance to PEA was obtained. Following the acquisition of tolerance, chronic administration of cocaine was terminated, and the discriminability of 5.0 mg/kg was tested every other day for loss of tolerance. After 8 days the ED50 returned to 5.0 mg/kg.

The Effect of Microeconomics Instruction on Interventionist/Noninterventionist Attitudes

Description: The purpose of the study is to determine if there is an effect on intervention/nonintervention attitudes associated with an introductory microeconomics class. The population consisted of all students enrolled in eighteen sections of Economics 1100 during the Fall semester, 1984, at North Texs State University. There were seven sections of Economics 1100, ten sections of Sociology 1510, and ten sections of Political Science 2010 used as control groups. The instruments used for pretesting and posttesting were the twenty-three item Attitude Scale and Demographic Questionnaire. The Attitude Scale contained twelve intervention and eleven nonintervention questions. Intervention questions were reverse scored so that a high score is noninterventionist and a low score is interventionist. Data were analyzed using a multiple linear regression to determine how each variable affected the intervention/nonintervention student attitudes.
