A Comparison of Predicted and Actual Trophic Status of Lake Ray Roberts, Texas Based on Chlorophyll A (open access)

A Comparison of Predicted and Actual Trophic Status of Lake Ray Roberts, Texas Based on Chlorophyll A

Two years before impoundment, the trophic status of Lake Ray Roberts was predicted by applying the total phosphorus input into the Organization for Economic Cooperation and Development (OECD) eutrophication model. Predicted mean summer epilimnetic (MSE) chlorophyll a of Elm Fork arm, Isle duBois arm and Main Body were in the eutrophic category of the OECD model. Observed MSE chlorophyll a two years after impoundment of Elm Fork arm, Isle duBois and Main Body had not reached their predicted means and were at the mesotrophic-eutrophic boundary of the OECD model. Six years after impoundment, observed MSE chlorophyll a for Main Body, was closer to its predicted mean and in the eutrophic category of the OECD model. Six years after impoundment, Elm Fork arm was the most productive area of Lake Ray Roberts. Observed means of chlorophyll a, total phosphates, suspended solids and turbidity were often highest in the Elm Fork arm. Wastewater effluent from Gainesville and Valley View, TX, had an impact on productivity in Elm Fork arm.

The Effects of Organic Surface Amendments on Soil Nutrients and Initial Tree Establishment (open access)

The Effects of Organic Surface Amendments on Soil Nutrients and Initial Tree Establishment

This study examined the effects of replicating woodland soil surface horizonation on the nutrient status of underlying soils and the initial establishment and growth of trees. A total of 283 container grown trees were planted in a bufferzone around a future landfill site. Control amendments consisted of an 8 cm layer (0.5 m3) of wood chips applied in a circular area of 4.6 m2 around the trees' planting pit. For the treatment, a 2.5 cm layer of composted biosolids (0.15 m3 or 80 Mg/ha) was applied in a circular area of 4.6 m2 around the trees' planting pit followed by an 8 cm layer (0.5 m3) of wood chips. The results indicate that the replication of woodland soil surface attributes using composted biosolids can significantly improve the nutrient status of underlying soil. Some significant effects were seen under control conditions, too. However, the effects on tree establishment and growth parameters were, for the most part, not statistically significant.

AIDS Preventative Behavior Among Taiwanese University Students (open access)

AIDS Preventative Behavior Among Taiwanese University Students

This study used the Health Belief Model to examine the predictors of AIDS preventive behavior. The independent variables were the variables of individual perception, modifying factors (psychological variables), and likelihood variables. The respondents, the Taiwanese students of the University of North Texas, were influenced both by Chinese sexuality and Western values in their AIDS-risk behavior. The results revealed that 90% of the respondents were misinformed on the availability of AIDS vaccine. In addition, a majority of the students were either abstaining from sex or practicing monogamy. Using Pearson's correlation coefficient and multiple regression analysis, this study found that the psychological variables rather than cognitive variables significantly influenced the respondents' AIDS preventive behavior. Finally, suggestions were made for future research on AIDS, and for AIDS preventive behavior campaigns.

A Comparison of Academic Stress Experienced by Students at an Urban Community College and an Urban University

The present study compared the academic stress levels of 450 college sophomore students at a public university and a public two-year college. This investigation also explored the levels of academic stress by institutional type, age, gender, and ethnicity. Data were obtained from having the subjects complete the Academic Stress Scale, a questionnaire which lists thirty five stress items found in the college classroom. Analysis of variance and t-tests were used to analyze the data. There were 225 subjects each in the community college group and the university group. The university group had a statistically significant higher mean stress score than the community college group. 294 traditional age (23 and younger) and 156 nontraditional age (24 and over) subjects stress levels were compared. It was found that the traditional age college student group experienced a statistically significant higher academic stress level in both academic settings. Group means were compared between the stress scores of 245 female and 205 male subjects. At both the community college and university levels, the female group had a statistically significant higher level of academic stress. The academic stress levels were also compared according to ethnicity. The minority group consisted of 104 subjects and 346 subjects comprised …

Family Background and Structure of High Academic Achievers (open access)

Family Background and Structure of High Academic Achievers

This study examines the influence of family background and structure on academic achievement. The research focuses on the 11th- and 12th-grade population in the Texas Academy of Mathematics and Science (TAMS) at the University of North Texas, Denton. The study examines the variables in family background and family structure that contribute to the students' high academic achievement. Twelve hypotheses related to parents, home environment, family structure and interaction, family roles, and family values are proposed. The multivariate analysis shows that the variables being read to, reading independently, fathers' education, mothers' education, and ethnicity are significant in impacting academic achievement. The study underlines the fact that multiple factors in family structure and background have an influence on academic achievement.

Library CD-ROM LAN Performance and Patron Use: a Computer Simulation Model

In this study, a computer simulation model for library CD-ROM LAN systems was created. Using this model, the system optimization problems were examined. The simulation model imitated the process of the actual decision variables changing their values and generated the corresponding results. Under a certain system environment, if the values of decision variables are changing, the system performances are getting changed also. This study investigated these relationships with the created model. The system users' interarrival time, service time, and other relevant data were collected on randomly selected days in a university library. For data collection, both of the observation and the system automatic metering software were used. According to the collected data, a discrete events simulation model was created with GPSS/H. The simulation model was proven valid and accurate by a pilot test and by the calculation with queuing theory. Statistical tests were used for data comparison and analysis. In addition, animation technique was used to show the simulation process by using Proof Animation. By this technique, the simulation process was monitored on the screen.

Life-Style Themes of Women Who Emerge as Leaders in Small Group Settings (open access)

Life-Style Themes of Women Who Emerge as Leaders in Small Group Settings

This study investigated the effects of personality characteristics on emergent leadership in small group settings. Two instruments were used to assess personality factors: The BASIS-A and the California Personality Inventory (CPI). A sociometric tool was developed to elicit leader ranking of female group members. The BASIS-A, was used to test for Taking Charge and Wanting Recognition lifestyles in women who emerged as leaders. The CPI was used to assess female emergent leaders for Dominance and Leadership Potential. The two instruments and a sociometric form were distributed to 115 female graduate counselor-in-training students the last week of their group counseling experience. This survey resulted in 55 respondents (N=55) from eleven discussion groups. It was expected that women who had the highest averaged leader rank would demonstrate higher test scores in Dominance, Leadership Potential, Taking Charge, and Wanting Recognition than women who received a lower averaged leader rank. It was also thought that these four test factors would be highly related. If so, a case would be made to use the BASIS-A as an emergent leader assessment tool because it is consistently based in one psychological theory. No significant effect was found between the highest leader rank and three of the test …

Assessing Defensiveness with the PAI: a Cross Validational Study

The use of scales on the Personality Assessment Inventory (PAI) to detect defensiveness in criminal and nonclinical samples was evaluated. Forty-five male inmates of a county jail and 38 male undergraduate psychology students were provided with incentives to complete the PAI under two conditions: standard instructions and experimental instructions to feign a specific, positive role. The sequence of instructions was counterbalanced in both samples for the purpose of examining ordering effects. A repeated measures multivariate analysis of variance (MANOVA) was performed, yielding significant main effects of condition, group and order. Additionally, a step-wise discriminant function analysis significantly predicted group membership (i.e., subjects under honest and faking conditions) with a hit rate = 84.4%. Finally, a more effective cutting score for the Positive Impression scale was recommended.

The Effects of a Performance Improvement Strategy in a Work Team Setting: a Case Study (open access)

The Effects of a Performance Improvement Strategy in a Work Team Setting: a Case Study

A popular approach to operating organizations in the 1990s is the implementation of work teams. The current literature offers little information on the use of performance management techniques in work team settings. This case study examined the effects of employing a performance improvement strategy on employee performance in a work team environment comprised of part-time graduate students. The performance improvement strategy included composing job descriptions, job aids (e.g., work organization charts), task request logs and posting weekly and monthly performance feedback. Improvements were observed in some aspects of team performance. Some of the improvement was due to task clarification and improved scheduling produced by the antecedent interventions. Performance feedback had little effect on measured performance but seemed to facilitate discussion and problem-solving.

Improving the Quality of Hotel Banquet Staff Performance: a Case Study in Organizational Behavior Management

The banquet staff at a north Texas hotel were responsible for setting up 11 different functions (e.g., buffet dinners) for conferences and meetings. The functions were often set up late and items were often omitted. An analysis suggested that performance problems were the result of weak antecedents, inefficient work procedures, inadequate training and a lack of motivating consequences. An intervention consisting of task checklists, feedback, goal setting, monetary bonuses, training and job aids was designed to enhance the accuracy and timeliness of function setups. Performance increased from an average of 68.8% on the quality measure (accuracy plus timeliness) in baseline, to 99.7% during the intervention phase. Performance decreased to 82.3% during a follow-up phase in which parts of the intervention were discontinued by hotel management. Performance increased to 99.3% with the reintroduction of the intervention phase.

Magical Contagion and AIDS Scale: Development and Validation (open access)

Magical Contagion and AIDS Scale: Development and Validation

A Magical Contagion and AIDS Scale was developed to address problems with existing Contagion and AIDS measures. Magical Contagion is an influence that exists after contact is terminated. It is comprised of Permanence, Holographic Effects, Moral Germ Conflation and Backward Action. Data from 280 undergraduates revealed low mean levels of Magical Contagion and AIDS. Contagion effects did not differ on demographic variables. Content validity, criterion-related validity, discriminate validity, and internal consistency were evaluated. Significant correlations were found between the Contagion Scale and Merging/Separation and Homophobia Scales. Negative correlations were found between the Contagion scale and the AIDS knowledge and social desirability scales. Alpha reliabilities were high (a > .93) for the Contagion scale and subscales. Factor analysis suggested the existence of a single factor and mixed support for three factors.
