Evaluation of the Chlorophyll/Fluorescence Sensor of the YSI Multiprobe: Comparison to an Acetone Extraction Procedure

Evaluation of the Chlorophyll/Fluorescence Sensor of the YSI Multiprobe: Comparison to an Acetone Extraction Procedure

Date: May 2001
Creator: Lambert, Patricia
Description: The purpose of this study was to examine the suitability of the YSI model 6600 Environmental Monitoring System (multiprobe) for long term deployment at a site in Lewisville Lake, Texas. Specifically, agreement between a laboratory extraction procedure and the multiprobe chlorophyll/fluorescence readings was examined. Preliminary studies involved determining the best method for disrupting algal cells prior to analysis and examining the precision and linearity of the acetone extraction procedure. Cell disruption by mortar and pestle grinding was preferable to bath sonication. Comparison of the chlorophyll/fluorescence readings from the multiprobe and the extraction procedure indicated that they were significantly correlated but temperature dependent.

Evaluation of the Developmental Effects and Bioaccumulation Potential of Triclosan and Triclocarban Using the South African Clawed Frog, Xenopus Laevis

Evaluation of the Developmental Effects and Bioaccumulation Potential of Triclosan and Triclocarban Using the South African Clawed Frog, Xenopus Laevis

Date: December 2010
Creator: King, Marie Kumsher
Description: Triclosan (TCS) and triclocarban (TCC) are antimicrobials found in U.S. surface waters. This dissertation assessed the effects of TCS and TCC on early development and investigated their potential to bioaccumulate using Xenopus laevis as a model. The effects of TCS on metamorphosis were also investigated. For 0-week tadpoles, LC50 values for TCS and TCC were 0.87 mg/L and 4.22 mg/L, respectively, and both compounds caused a significant stunting of growth. For 4-week tadpoles, the LC50 values for TCS and TCC were 0.22 mg/L and 0.066 mg/L; and for 8-week tadpoles, the LC50 values were 0.46 mg/L and 0.13 mg/L. Both compounds accumulated in Xenopus. For TCS, wet weight bioaccumulation factors (BAFs) for 0-, 4- and 8-week old tadpoles were 23.6x, 1350x and 143x, respectively. Lipid weight BAFs were 83.5x, 19792x and 8548x. For TCC, wet weight BAFs for 0-, 4- and 8-week old tadpoles were 23.4x, 1156x and 1310x. Lipid weight BAFs were 101x, 8639x and 20942x. For the time-to-metamorphosis study, TCS showed an increase in weight and snout-vent length in all treatments. Exposed tadpoles metamorphosed approximately 10 days sooner than control tadpoles. For the hind limb study, although there was no difference in weight, snout-vent length, or hind limb ...

Evaluation of the Economic, Social, and Biological Feasibility of Bioconverting Food Wastes with the Black Soldier Fly (Hermetia illucens)

Evaluation of the Economic, Social, and Biological Feasibility of Bioconverting Food Wastes with the Black Soldier Fly (Hermetia illucens)

Date: August 2004
Creator: Barry, Tami
Description: Food waste in the waste stream is becoming an important aspect of integrated waste management systems. Current efforts are composting and animal feeding. However, these food waste disposal practices rely on slow thermodynamic processes of composting or finding farmers with domestic animals capable of consuming the food wastes. Bioconversion, a potential alternative, is a waste management practice that converts food waste to insect larval biomass and organic residue. This project uses a native and common non-pest insect in Texas, the black soldier fly, which processes large quantities of food wastes, as well as animal wastes and sewage in its larval stage. The goal of this research is to facilitate the identification and development of the practical parameters of bioconversion methods at a large cafeteria. Three major factors were selected to evaluate the practicality of a bioconversion system: (1) the biological constraints on the species; (2) the economic costs and benefits for the local community; (3) the perception of and interaction between the public and management agencies with respect to the bioconversion process. Results indicate that bioconversion is feasible on all levels. Larvae tolerate and consume food waste as well as used cooking grease, reducing the overall waste volume by 30-70% ...

An Evaluation of the Effect of a Specific Perceptual Training Program on Classroom Skills in Kindergarten

An Evaluation of the Effect of a Specific Perceptual Training Program on Classroom Skills in Kindergarten

Date: May 1977
Creator: Cook, Grace H.
Description: The purpose of the evaluation was to test effectiveness of a visual, visual-motor, and auditory perceptual skills training program devised by Dr. Jerome Rosner, and to confirm or deny application of this training to improved classroom skills. Subjects were 38 kindergarten children, 20 in the Contrast Group, and 18 in the Experimental Group. Both groups received the same training in the basic curriculum of readiness skills. The Experimental Group also received training in the Visual Analysis and Auditory Analysis Skills programs. Pretests and posttests were administered, tabulated, and analyzed. Differences in raw score means were sufficient to indicate more than a chance factor and all tests demonstrated a plus factor for children in the Experimental Group.

An Evaluation of the Effect of Learning Styles and Computer Competency on Students' Satisfaction on Web-Based Distance Learning Environments

An Evaluation of the Effect of Learning Styles and Computer Competency on Students' Satisfaction on Web-Based Distance Learning Environments

Access: Use of this item is restricted to the UNT Community.
Date: August 2003
Creator: Du, Yunfei
Description: This study investigates the correlation between students' learning styles, computer competency and student satisfaction in Web-based distance learning. Three hundred and one graduate students participated in the current study during the Summer and Fall semesters of 2002 at the University of North Texas. Participants took the courses 100% online and came to the campus only once for software training. Computer competency and student satisfaction were measured using the Computer Skill and Use Assessment and the Student Satisfaction Survey questionnaires. Kolb's Learning Style Inventory measured students' learning styles. The study concludes that there is a significant difference among the different learning styles with respect to student satisfaction level when the subjects differ with regard to computer competency. For accommodating amd diverging styles, a higher level of computer competency results in a higher level of student satisfaction. But for converging and assimilating styles, a higher level of computer competency suggests a lower level of student satisfaction. A significant correlation was found between computer competency and student satisfaction level within Web-based courses for accommodating styles and no significant results were found in the other learning styles.

An Evaluation of the Effects of a Pay for Performance Plan on Productivity of Employees of a Professional Services Firm

Date: December 2002
Creator: Porter, Melanie
Description: This study examined the effects of a productivity-indexed pay for performance plan in a professional services firm. The new plan was implemented after productivity decreased under an existing plan. Performance of staff and senior level accountants was analyzed across three departments under a three-year baseline and a two-year intervention period. Several measures of productivity indicated that the intervention was effective in improving production, especially for employees with full annual workloads. Percentage of salaries earned in incentives was comparable for both the baseline and intervention periods. Possible explanations for trends in the data, weaknesses in the plan, and implications for future research are also discussed.

An Evaluation of the Effects of an Abridged Parent Training Program on Parent-child Interactions in the Home

Date: December 2008
Creator: Jones-Hamilton, Allison M.
Description: This study examined the effects of a condensed parent training program on parent-child interactions in the home. Two parents participated in a positive parenting workshop that included explicit training of four skills and indirect training of two additional skills. To determine skill acquisition, both parents performed role plays and completed written exams pre- and post-training. Role play assessment results showed improvements in all skill areas for both participants. Written assessment results showed improvements for all skills directly taught except one. Multiple measures were examined in the home prior to and following the workshop to assess generalization. Results showed an increase in positive interactions and decrease in coercive interactions and undesirable child behavior for both participants.
