The Effectiveness of Speech Recognition as a User Interface for Computer-Based Training

Description: Some researchers are saying that natural language is probably one of the most promising interfaces for use in the long term for simplicity of learning. If this is true, then it follows that speech recognition would be ideal as the interface for computer-based training (CBT). While many speech recognition applications are being used as a means for a computer interface, these are usually confined to controlling the computer or causing the computer to control other devices. The user input or interface has been the recipient of a strong effort to improve the quality of the communication between man and machine and is proposed to be a dominant factor in determining user productivity, performance, and satisfaction. However, other researchers note that full natural interfaces with computers are still a long way from being the state-of-the art with technology. The focus of this study was to determine if the technology of speech recognition is an effective interface for an academic lesson presented via CBT. How does one determine if learning has been affected and how is this measured? Previous research has attempted quantify a learning effect when using a variety of interfaces. This dissertation summarizes previous studies using other interfaces and those using speech recognition. It attempted to apply a framework used to measure learning effectiveness in some of these studies to quantify the measurement of learning when speech recognition is used as the sole interface. The focus of the study was on cognitive processing which affects short-term memory and in-turn, the effect on original learning (OL). The methods and procedures applied in an experimental study were presented.

The Effectiveness of Substance use Measures in the Detection of Denial and Partial Denial

Description: Many substance users deny their substance use to avoid negative consequences, thus diluting the accuracy of assessment. To address this issue, indirect items are often included on substance use measures to identify those who deny their use. The purpose of this study was to examine the effect of complete denial and partial denial on substance use measures. Partial denial, also termed denial of effects, is the denial of substance use interfering in multiple domains of a person's functioning. The study used a mixed within- and between-subjects design with participants from a dual diagnosis inpatient unit. Each participant completed the study under two different conditions which include an honest condition and an experimental condition (either complete denial or partial denial). Results show that partial denial is distinctly different from complete denial across three self-report substance use measures. Importantly, substance users engaging in these denial conditions were often undetected by these measures.

The effectiveness of the conservation of human beings and of soil by the CCC camp in Denton, Texas

Description: The organization of the Emergency Conservation Work was found to possess many faults. The Seventy-Fifth Congress, taking cognizance of some of the more glaring imperfections, approved a measure reorganizing and re-establishing the Emergency Conservation Work under the name of The Civilian Conservation Corp. The bill eliminated many of the defects of the former organization, and invested authority and defined duties and regulations in such a manner that a more efficient institution resulted.

The Effectiveness of the Geriatric Depression Scale to Distinguish Apathy From Depression in Alzheimer's Disease and Related Dementias.

Description: Early detection of Alzheimer's disease (AD) and related dementias in the elderly is critical for improving treatment methods and is a necessary component for improving public health interventions. One of the earliest and most common behavioral syndromes of AD is apathy and is associated with executive dysfunction. Apathy in AD is often misdiagnosed as depression due to an overlap in symptoms. Studies that have found depression to be associated with executive dysfunction have not always controlled for the presence of apathy. The Geriatric Depression Scale (GDS) is a widely used instrument designed to assess depression in the elderly. This study utilized the GDS and a set of standard neuropsychological instruments to investigate the relationship between apathy, depression, and executive functions in individuals with AD and related dementias. The first objective of this study was to determine if apathy has a greater impact on executive functions compared to depression in AD and related dementias. The second objective was to determine the effectiveness of the GDS as a screen for apathy. The results of the analyses did not support the hypotheses. However, exploratory analyses suggested a possible non-linear relationship with apathy and various levels of dementia severity. Exploratory analysis also suggested mean levels of endorsement for apathy varied by diagnosis. Further research is warranted to investigate this relationship and the GDS endorsement patterns for caregivers regarding their impression of the demented individual.

Effectiveness of the Neurobehavioral Cognitive Status Examination in Assessing Alzheimer's Disease

Description: Accurate, early diagnosis of Alzheimer's Disease is becoming increasingly important in light of its growing prevalence among the expanding older-aged adult population. Due to its ability to assess multiple domains of cognitive functioning and provide a profile of impairment rather than a simple global score, the Neurobehavioral Cognitive Status Examination (NCSE) is suggested to better assess such patterns of cognitive deficit for the purpose of diagnosis. The performance of the NCSE was compared with that of the Mini-Mental State Examination (MMSE) for diagnostic sensitivity in a sample of patients diagnosed as having probable Alzheimer's Disease. The strength of correlation between severity of cognitive impairment on these tests and report of behavior problems on the Memory and Behavior Problems Checklist (MBPC) was also explored, as was performance on the NCSE and report of behavior problems using the MBPC in predicting Single Photon Emission Computed Tomography (SPECT) scan results. The NCSE was found to exhibit greater sensitivity to physician diagnosis of probable Alzheimer's Disease relative to two versions (Serial 7's or WORLD) of the MMSE (.90, .77 and .68, respectively). While both measures were found to correlate significantly with the report of behavior problems, only a moderate proportion (NCSE = .22 and MMSE = .33) of the explained variance was accounted for by either test. Severity of cognitive impairment on the NCSE was found to be significant, though small in estimate of its effect size, for predicting the absence/presence of pathognomic findings on SPECT scans. In contrast, the report of behavior problems on the MBPC did not significantly predict SPECT scan outcomes. The NCSE would appear to be a sensitive tool for the identification of the extent and severity of cognitive impairment found among demented individuals; however, it may be "over"-sensitive to such diagnosis. Although relationships between cognitive impairment and behavior problems ...

Effectiveness of the Problem-Solving Method in Developing Thinking Ability in Homemaking Students

Description: This study attempts to compare the thinking abilities of homemaking girls with the thinking abilities of girls not taking homemaking. By emphasizing the problem-solving method in the teaching of an experimental unit, it proposes to determine whether homemaking students show greater gains in thinking ability at the end of the school year than non-homemaking students. The investigator proposes to find out if the student taught by techniques of problem-solving forms thinking habits superior to habits formed by those students who have not been taught by this method as extensively as homemaking students.

The Effectiveness of Using Lego Mindstorms Robotics Activities to Influence Self-regulated Learning in a University Introductory Computer Programming Course.

Description: The research described in this dissertation examines the possible link between self-regulated learning and LEGO Mindstorms robotics activities in teaching concepts in an introductory university computer programming course. The areas of student motivation, learning strategies, and mastery of course objectives are investigated. In all three cases analysis failed to reveal any statistically significant differences between the traditional control group and the experimental LEGO Mindstorms group as measured by the Motivated Strategies for Learning Questionnaire and course exams. Possible reasons for the lack of positive results include technical problems and limitations of the LEGO Mindstorms systems, limited number and availability of robots outside of class, limited amount of time during the semester for the robotics activities, and a possible difference in effectiveness based on gender. Responses to student follow-up questions, however, suggest that at least some of the students really enjoyed the LEGO activities. As with any teaching tool or activity, there are numerous ways in which LEGO Mindstorms can be incorporated into learning. This study explores whether or not LEGO Mindstorms are an effective tool for teaching introductory computer programming at the university level and how these systems can best be utilized.

Effector Response of the Aspartate Transcarbamoylase From Wild Type Pseudomonas Putida and a Mutant with 11 Amino Acids Deleted at the N-terminus of PyrB.

Description: Like its enteric counterpart, aspartate transcarbamoylase (ATCase) from Pseudomonas putida is a dodecamer of two different polypeptides. Unlike the enterics, the Pseudomonas ATCase lacks regulatory polypeptides but employs instead inactive dihydroorotases for an active dodecamer. Previous work showed that PyrB contains not only the active site but also the effector binding sites for ATP, UTP and CTP at its N-terminus. In this work, 11 amino acids were deleted from the N-terminus of PyrB and the ATCase with the truncated protein was expressed in E. coli pyrB- and purified. The wild type enzyme was similarly treated. Velocity-substrate plots without effectors gave Michaelis-Menten kinetics in all cases. Deleting 11 amino acids did not affect dodecameric assembly but altered effector responses. When carbamoylphosphate was varied, the mutant enzyme was inhibited by UTP while the wild type enzyme was activated 2-fold. When the aspartate was varied, CTP had no effect on the mutant enzyme but strongly inhibited the wild type enzyme.

Effects and Mediation of Child-centered Play Therapy on Young Children Who Are Anxious

Description: Anxiety is one of the most pervasive childhood disorders, with a poor prognosis if left untreated. Traditional methods of treating anxiety have been less effective with young children. Based on theoretical assumptions regarding the potential effectiveness of child-centered play therapy (CCPT) as a treatment approach, I sought to explore the effects and mediating factors of CCPT on young children with symptoms of anxiety. Fifty-three participants between the ages of 6 to 8 years old were recruited from four elementary schools, including 36 males and 17 females. Of participants, 11 were African American, 24 were Caucasian, 10 were Hispanic/Latino, one was Asian, and seven were biracial. Twenty-five participants were randomly assigned to an experimental group receiving a mean of 15 sessions of individual CCPT, and 28 participants were assigned to an 8-session active control group. Five factorial analyses of variance (ANOVA) were conducted applying an alpha level of .05 for interpretation of statistical significance and Cohen’s d to assess practical significance. ANOVA results indicated a statistically significant interaction with a large effect size on Total Anxiety score of the Revised Children’s Manifest Anxiety Scale-2nd edition (p = .013, d = .715). Subscale ANOVA results indicated a statistically significant interaction effect with large effect size on the Worry subscale (p = .006, d = .795), no statistically significant interaction on the Defensiveness subscale (p = .710, d = .110), no statistically significant interaction but moderate effect size on the Physiological subscale (p = .076, d = .506), and no statistically significant interaction but moderate effect size on the Social Anxiety subscale (p = .162, d = .398). Statistically significant differences with large practical effects were found in total anxiety and worry, suggesting that children who received CCPT decreased their overall levels of anxiety and worry whereas children who were in the active ...
