An exploration of the diffusion of a new technology from communities of practice perspective: Web services technologies in digital libraries.

An exploration of the diffusion of a new technology from communities of practice perspective: Web services technologies in digital libraries.

Date: August 2007
Creator: Oguz, Fatih
Description: This study explored and described decision factors related to technology adoption. The research used diffusion of innovations and communities of practice (CoP) theoretical frameworks and a case study of Web services technology in the digital library (DL) environment to develop an understanding of the decision-making process. A qualitative case study approach was used to investigate the research problems and data were collected through semi-structured interviews, documentary evidence (e.g., meeting minutes), and a comprehensive member check. The research conducted face-to-face and phone interviews with seven respondents with different job titles (administraive vs. technical) from five different DL programs selected based on distinctive characteristics such as size of the DL program. Findings of the research suggested that the decision-making process is a complex process in which a number of factors are considered when making technology adoption decisions. These factors are categorized as organizational, individual, and technology specific factors. Further, data showed that DL CoPs played an important role in enabling staff members of a DL program to access up-to-date and experienced-based knowledge, provided a distributed problem solving and learning environment, facilitating informal communication and collaborative activities, and informing the decision-making process.

An Exploration of the Ground Water Quality of the Trinity Aquifer Using Multivariate Statistical Techniques

An Exploration of the Ground Water Quality of the Trinity Aquifer Using Multivariate Statistical Techniques

Date: August 2011
Creator: Holland, Jennifer M.
Description: The ground water quality of the Trinity Aquifer for wells sampled between 2000 and 2009 was examined using multivariate and spatial statistical techniques. A Kruskal-Wallis test revealed that all of the water quality parameters with the exception of nitrate vary with land use. A Spearman’s rho analysis illustrates that every water quality parameter with the exception of silica correlated with well depth. Factor analysis identified four factors contributable to hydrochemical processes, electrical conductivity, alkalinity, and the dissolution of parent rock material into the ground water. The cluster analysis generated seven clusters. A chi-squared analysis shows that Clusters 1, 2, 5, and 6 are reflective of the distribution of the entire dataset when looking specifically at land use categories. The nearest neighbor analysis revealed clustered, dispersed, and random patterns depending upon the entity being examined. The spatial autocorrelation technique used on the water quality parameters for the entire dataset identified that all of the parameters are random with the exception of pH which was found to be spatially clustered. The combination of the multivariate and spatial techniques together identified influences on the Trinity Aquifer including hydrochemical processes, agricultural activities, recharge, and land use. In addition, the techniques aided in identifying areas ...

An Exploration of the Possible Use of the Sociometric Test in Studying Residents of Homes for the Aged

An Exploration of the Possible Use of the Sociometric Test in Studying Residents of Homes for the Aged

Date: 1950
Creator: Secker, Martin D.
Description: It is proposed in this thesis to explore the possible use of the Sociometric test as a measure of the personal social factor in old age. It is further proposed to gather sociometric data by administering a sociometric test to the residents of two homes for aged persons in Dallas County, Texas, and to illustrate by sociograms and tables the uses for which such data might be of value in research designed to investigate the personal social factor in old age.

An Exploration of the Relationship Between Principal Leadership Efficacy, Principal Computer Self-Efficacy, and Student Achievement

An Exploration of the Relationship Between Principal Leadership Efficacy, Principal Computer Self-Efficacy, and Student Achievement

Date: May 2010
Creator: Brown, Shelia
Description: The purpose of this study was to examine whether or not relationships exist between principals' technology proficiency and student achievement as indicated by 2008 Texas Assessment of Knowledge and Skills (TAKS) ninth grade reading scaled scores. Secondly, the study examined whether or not relationships exist between principals' leadership self efficacy and student achievement as indicated in the 2008 Texas Assessment of Knowledge and Skills (TAKS) ninth grade reading scaled scores. Lastly, the select principal's personal and school demographic variables (principal gender, total years of experience as a professional, total years as principal at current school, total years of principal experience, highest degree earned, school economic status, school size) were considered within the study. The survey instruments used in this study were the Technology Proficiency Self Assessment Scale (TPSA) developed by Ropp in 2000 and the Principal's Self-Efficacy Scale (PSES) developed by Tschannen-Moran and Garies in 2004. A total of 129 Texas principal's participated in the study. Multiple regressions were utilized and effect size was considered to determine the strength of the relationship between variables. A statistical significance was found relating to the school's social economic status only when using both the PSES and the TPSA instruments. The effect sizes reported ...

An Exploration of the Relationship between Worry and Other Verbal Phenomena

An Exploration of the Relationship between Worry and Other Verbal Phenomena

Date: May 2008
Creator: O'Brien, Karen M.
Description: This study hypothesized a direct relationship among three verbal phenomena: derived relational responding, verbal intelligence, and worry. It also hypothesized that experiential avoidance would mediate the relationship between derived relational responding and worry. Overall, results from this study failed to support a relationship between worry and the other two verbal phenomena, however, results did support a relationship between derived relational responding and verbal intelligence. Additionally, results indicated a significant relationship between experiential avoidance and worry. Future research should clarify the relationship among the three primary variables of interest, improve measurement of these variables, be more sensitive to external validity, and promote the study of acceptance-based treatments that target experiential avoidance.

An exploration of the relationships among teacher efficacy, collective teacher efficacy, and teacher demographic characteristics in conservative Christian schools.

An exploration of the relationships among teacher efficacy, collective teacher efficacy, and teacher demographic characteristics in conservative Christian schools.

Date: August 2006
Creator: Egger, Karen J.
Description: The purpose of this study was to determine whether teachers' perceptions of self-efficacy and collective teacher efficacy are interrelated and how these two constructs may be impacted by teacher demographic characteristics, such as educational level, grade level taught, and number of years of teaching experience. This study focused entirely on the interrelationships of teacher efficacy and collective teacher efficacy in three suburban, conservative Christian schools in north Texas. Specifically, the demographic characteristics of age, gender, ethnicity, particular school campus, number of years teaching, number of years teaching at the current school, highest degree received, type of teacher certification, certification grade level and subject area, grade level taught, and particular subject taught were studied for the non-random, convenience sample of 216 kindergarten through twelfth grade teachers. A correlational analysis of teacher efficacy and collective teacher efficacy yielded a Pearson r of .35 at a statistically significant level (p < .01); combining these two variables with teacher demographic variables in multiple regression analyses confirmed the relationship between teachers' perceptions of teacher efficacy and collective efficacy at a statistically significant level (p < .001). A review of the squared structure coefficients in the first multiple regression analysis (R2 = .284, p < .001) ...

An Exploration of the Titrating-Delay Match-to-Sample Procedure with Pigeons

An Exploration of the Titrating-Delay Match-to-Sample Procedure with Pigeons

Date: December 2011
Creator: Friedel, Jonathan E.
Description: The delayed matching‐to‐sample (DMTS) procedure involves the insertion of a delay between the offset of a sample stimulus and the onset of an array of comparison stimuli; one of which is designated as the “correct” match for the sample on each trial. The procedure has served as the base preparation in which the effects of environmental variables on short‐term remembering and is, in many ways, responsible for a refined understanding of the phenomenon. Despite its utility, however, there are a few problems with the DMTS procedure – first, the procedure doesn’t adjust for individual differences and second, the conventional dependent measure, percent of correct trials, is not as sensitive as one might like. The titrating-delay matching to sample (TDMTS) procedure is a variant of the DMTS procedure in which the delays between sample and comparison are adjusted as a function of the subject’s performance. Stable measures of adjusted delay are not only sensitive measures of the performance of interest but they are also automatically tuned to differences across individuals. The study reported here continues our efforts to understand the dynamics of the TDMTS procedure so that it can be used to ask important questions related to short‐term remembering.

Exploration of Visual, Acoustic, and Physiological Modalities to Complement Linguistic Representations for Sentiment Analysis

Exploration of Visual, Acoustic, and Physiological Modalities to Complement Linguistic Representations for Sentiment Analysis

Access: Use of this item is restricted to the UNT Community.
Date: December 2014
Creator: Pérez-Rosas, Verónica
Description: This research is concerned with the identification of sentiment in multimodal content. This is of particular interest given the increasing presence of subjective multimodal content on the web and other sources, which contains a rich and vast source of people's opinions, feelings, and experiences. Despite the need for tools that can identify opinions in the presence of diverse modalities, most of current methods for sentiment analysis are designed for textual data only, and few attempts have been made to address this problem. The dissertation investigates techniques for augmenting linguistic representations with acoustic, visual, and physiological features. The potential benefits of using these modalities include linguistic disambiguation, visual grounding, and the integration of information about people's internal states. The main goal of this work is to build computational resources and tools that allow sentiment analysis to be applied to multimodal data. This thesis makes three important contributions. First, it shows that modalities such as audio, video, and physiological data can be successfully used to improve existing linguistic representations for sentiment analysis. We present a method that integrates linguistic features with features extracted from these modalities. Features are derived from verbal statements, audiovisual recordings, thermal recordings, and physiological sensors signals. The resulting ...

An exploration study of the relationship between effectiveness of filial therapy training groups and group cohesion.

An exploration study of the relationship between effectiveness of filial therapy training groups and group cohesion.

Date: May 2009
Creator: Reed, Kelly Layne
Description: This study examined the relationship of group cohesion among heterogeneous and homogeneous groups on individual treatment outcome of child-parent relationship therapy (CPRT). CPRT is a filial therapy model that targets the parent-child relationship as a means for preventing or improving child and/or family problems. This study included 30 parents or caregivers from 9 groups which met for 10 sessions. Participants qualified for this study if their groups ended with at least 3 group members and 2 leaders, all pretest and posttest data on their child between the ages of 2-11 was completed, and if they attended at least 6 of the 10 sessions. Correlation coefficients, t-tests, and effect sizes were calculated. Results demonstrated no statistically significant differences between pretests and posttests on the Child Behavior Checklist (CBCL) for all 30 participants; however, differences in measured effect (η2) between children identified with borderline and clinical behavior problems and children with normal behavior problems suggest that CPRT is more effective among children who demonstrate significant behavior problems. Perceived and observed group cohesion measurements demonstrated no significant difference at the individual outcome level. This finding suggests that group cohesion may not be related to individual outcome. Although there was no significant relationship between ...
