The Effects of Training History on Retention and Reacquisition of Stimulus Control

The Effects of Training History on Retention and Reacquisition of Stimulus Control

Date: August 2013
Creator: Tucker, Kathryn Lynn
Description: The purpose of this experiment was to study the effects of training history on retention and re-acquisition of stimulus control of previously learned behaviors. In Phase I, two pairs of behaviors were alternately trained. Circle and touch behaviors were trained concurrently until two consecutive errorless sessions were run. Spin and down behaviors were trained together in the same manner. Probe sessions, in which all four cues were presented, were conducted each time a pair of behaviors reached this criterion. Training of one pair did not occur until the other pair had reached criterion and probe sessions were run. Despite achieving the designated criterion during training, stimulus control changed during probes. During probe sessions, errors increased under the cues that were not currently being trained. In most cases, the type of errors emitted for each cue was the same as the behavior that was trained concurrently. The number of training sessions required to reach criterion accuracy was high during the first set of sessions and decreased over the course of the experiment. In Phase II, spin and circle behaviors were trained concurrently. The number of sessions required to reach stimulus control criteria remained low, and the number of errors emitted under ...

Effects of Triclosan, Triclocarban, and Caffeine Exposure on the Development of Amphibian Larvae.

Effects of Triclosan, Triclocarban, and Caffeine Exposure on the Development of Amphibian Larvae.

Date: August 2009
Creator: Palenske, Nicole Marie
Description: Triclosan and triclocarban are antimicrobials found in numerous consumer products, while caffeine is the most commonly consumed stimulant by humans. This study was undertaken to determine the effects of triclosan, triclocarban, and caffeine on the development and physiology of amphibian larvae. LC50 values of triclosan and triclocarban were determined after 96 hours for three North American larval species: Acris crepitans blanchardii, Bufo woodhousii woodhousii, Rana sphenocephala, and for a common amphibian developmental model: Xenopus laevis. Amphibian larvae were most sensitive to triclosan and triclocarban exposure during early development based upon 96-hour LC50 values. Heart rates for X. laevis and North American larvae exposed to triclosan were variable throughout development. However, significantly lower heart rates were observed in all larvae exposed to triclocarban. Metabolic rates of X. laevis and R. sphenocephala larvae exposed to triclosan were significantly affected in larvae exposed to ½ LC50 and the LC50 concentration. Metabolic rates of X. laevis larvae exposed to triclocarban were significantly affected by exposure to ½ LC50 concentrations in three of four stages investigated. No significant differences were observed in North American larvae exposed to triclocarban. Tissue uptake, lipid uptake, tissue bioconcentration factor (BCF) and lipid BCF of triclosan and triclocarban were investigated ...

Effects of Turbidity on Gilling Rates and Oxygen Consumption on Green Sunfish, Lepomis cyanellus

Effects of Turbidity on Gilling Rates and Oxygen Consumption on Green Sunfish, Lepomis cyanellus

Date: May 1974
Creator: Horkel, John Duane
Description: Laboratory studies conducted at 5, 15, 25, and 35 C measured changes in gilling rates and oxygen consumption of green sunfish in response to exposure to bentonite clay suspensions. The tests indicate that gilling rates are not affected by bentonite clay suspensions below 2125 FTU at 5 C, 1012 FTU at 15 C, and 898 FTU at 25 C. At turbidity levels exceeding 1012 FTU at 15 C and 898 at 25 C, gilling rates increased 50-70%. Tests were inconclusive at 35 C. Oxygen consumption rates were found to be unaffected by turbid suspensions below 3500 FTU at all four temperatures. Evidence suggests that increased gilling rates under highly turbid conditions are a means of compensating for reduced respiratory efficiency and a strategy for maintaining a constant oxygen uptake. Evidence indicates that the cost of increased gilling rates is probably met by a reduction in activity.

The Effects of Two Types of Consequence Delivery on Task Acquisition.

The Effects of Two Types of Consequence Delivery on Task Acquisition.

Date: August 2005
Creator: Jenkins, Juliet
Description: The effects of two consequence delivery methods on task acquisition were evaluated within a multi-element design. A typical 3 year-old child and a 4 year-old child with autism participated in this study. The task for both children was to select a picture after the experimenter said its name. The consequence in one condition consisted of the experimenter handing the edible item to the children. The consequence in the other condition consisted of the children retrieving the edible item directly from the apparatus, located in a crevice underneath each picture. Results show slightly quicker acquisition in the condition where children retrieved the edible consequence. However, it is possible that other variables had greater influence on the task acquisition.

Effects of UE Speed on MIMO Channel Capacity in LTE

Effects of UE Speed on MIMO Channel Capacity in LTE

Access: Use of this item is restricted to the UNT Community.
Date: August 2016
Creator: Shukla, Rahul
Description: With the introduction of 4G LTE, multiple new technologies were introduced. MIMO is one of the important technologies introduced with fourth generation. The main MIMO modes used in LTE are open loop and closed loop spatial multiplexing modes. This thesis develops an algorithm to calculate the threshold values of UE speed and SNR that is required to implement a switching algorithm which can switch between different MIMO modes for a UE based on the speed and channel conditions (CSI). Specifically, this thesis provides the values of UE speed and SNR at which we can get better results by switching between open loop and closed loop MIMO modes and then be scheduled in sub-channels accordingly. Thus, the results can be used effectively to get better channel capacity with less ISI. The main objectives of this thesis are: to determine the type of MIMO mode suitable for a UE with certain speed, to determine the effects of SNR on selection of MIMO modes, and to design and implement a scheduling algorithm to enhance channel capacity.

The Effects of Using Children's Literature with Adolescents in the English As a Foreign Language Classroom.

Date: December 2006
Creator: Belsky, Stella
Description: This study provides quantitative and qualitative data about the effects of using children's literature with adolescents in a language classroom and the role of children's literature in students' second/foreign language development, including listening, speaking, reading, and writing skills. The study presents qualitative data about the role of children's literature in developing more positive attitudes toward reading in the second/foreign language and toward reading in general. With literature being a model of a culture, presenting linguistic benefits for language learners, teaching communication, and being a motivator in language learning, this study presents empirical data that show that inclusion of children's literature in adolescents' second/foreign language classroom promotes appreciation and enjoyment of literature, enhances the development of language skills, stimulates more advanced learning, and promotes students' personal growth.

The Effects of Using Information Technology to Support Evaluation of Feedback and Implementation of Adjustments in an Organization's Strategic Planning Process

The Effects of Using Information Technology to Support Evaluation of Feedback and Implementation of Adjustments in an Organization's Strategic Planning Process

Date: May 1997
Creator: Kemm, Elizabeth
Description: Organizations that must respond quickly to environmental pressures look for tools to assist in that response. Information technology may be one tool to facilitate the response. In this study the possible effects of using information technology, specifically a decision support system, in the feedback segment of one organization's strategic management loop were examined. The organization was one region of the Board of Probation and Parole in a central state. Personnel included administrators, parole officers and clerical workers. The information technology was an off-the-shelf software product called PlanRight. This study is significant for two reasons: a new application for information technology was examined and the adequacy of a generic computerized tool designed to be suitable for various operations was explored. This study was a case study. Two months of data were taken prior to the implementation of the decision support system, and four months of data were taken after the system was implemented. Questionnaire data taken before system implementation provided descriptive characteristics of the organization. Follow-up surveys and interviews at the conclusion of the study were used to evaluate employee perceptions. The study was done in three phases. During phase one questionnaires were distributed and returned. During phase two, goals, plans ...

Creator: Manrique, Carissa Janice
Description: A study was conducted to investigate the relationships between cybergaming treatment groups and the control group (N = 99: ncontrol = 8; nlogic = 29; nspatial = 30; ncombination = 32) with success in the organic chemistry I course as measured by achievement over a 10-week period. The treatment groups included logic training, spatial training, and combination logic-spatial training. Students' ability was measured by pre/post exams using the Group Assessment of Logical Thinking (GALT) to measure logic ability, Purdue Visualizations of Rotations (ROT) test to measure spatial skills, and the General-Organic-Biochemistry (GOB) Exam to measure content attainment. Finally, students' responses about participation in this experience were evaluated using open- and closed-ended questions on a self-developed survey. A second study was conducted to evaluate the relationship between the cybergaming treatment and control groups (N = 88: nexperimental = 27; ncontrol = 61) with success in the general chemistry I course as measured by achievement and final course averages and grades. The cybergaming treatment group underwent intensive combination logic-spatial training for 10 weeks. Students' progress was measured using three pre/post instruments: Group Assessment of Logical Thinking (GALT) measured logic ability, Purdue Visualizations of Rotations (ROT) Test measured spatial skills, and the California ...

Effects of Vegetation Structure and Canopy Exposure on Small-scale Variation in Atmospheric Deposition Inputs to a Mixed Conifer Forest in California

Effects of Vegetation Structure and Canopy Exposure on Small-scale Variation in Atmospheric Deposition Inputs to a Mixed Conifer Forest in California

Date: May 2014
Creator: Griffith, Kereen
Description: Data on rates of atmospheric deposition is limited in many montane ecosystems, where high spatial variability in meteorological, topographic, and vegetation factors contributes to elevated atmospheric inputs and to the creation of deposition hotspots. Addressing the ecological consequences of increasing deposition in these areas will require a better understanding of surface controls influencing atmospheric deposition rates at both large and small-scales. The overarching objective of this thesis research was to understand the influence of vegetation structure and canopy exposure on small-scale patterns of atmospheric sulfate, nitrate, and chloride deposition inputs to a conifer forest in the Santa Cruz Mountains, California. Throughfall ion fluxes (i.e., ions delivered in water that pass from the forest canopy to the forest floor), bulk deposition (i.e., primarily wet deposition), and rainfall data were collected during the rainy period from October 2012 to May 2013. Throughfall SO42-, Cl-, and NO3- fluxes were measured beneath eight clusters of Douglas fir (Pseudotsuga menziesii) trees (three trees per cluster) differing in tree size (i.e., diameter at breast height; DBH) and canopy exposure. In each cluster, a throughfall collector was placed 1-meter from the bole of an individual tree, for a total of 24 individual collectors. The position of each ...

Effects of Venture Team Demographic Characteristics on Team Interpersonal Process Effectiveness in Computer Related Venture Teams

Effects of Venture Team Demographic Characteristics on Team Interpersonal Process Effectiveness in Computer Related Venture Teams

Date: August 1996
Creator: Ochani, Manju
Description: In order to remain competitive, firms must be able to merge diverse, differentiated people into teams. In comparison to solo ventures, venture teams not only offer a broader base of physical and financial resources and varying points of view, but also positively influence the profitability, growth, and survivability potential of new ventures. Despite the growing importance and potential benefits offered by venture teams, relatively little is known about assembling and maintaining effective venture teams in the field of entrepreneurship. More specifically, information is needed to understand what composition and combination of demographic characteristics of team members would contribute to the effectiveness and success of a venture team. In this study the relationship between venture team demographic characteristics and team effectiveness (which is defined in terms of the interpersonal process of venture team members in their group activities) is investigated. The demographic characteristics examined include average age, age heterogeneity, average level of education, educational background heterogeneity, gender heterogeneity, and functional background heterogeneity. A field study, involving face-to-face and telephone interviews with the venture teams is used to gather data from40 computer related venture teams in a large midwest U.S. city. The venture teams are identified through the local Chambers of Commerce, ...
