Knowledge and Confidence of Speech-Language Pathologists Regarding Autism

Knowledge and Confidence of Speech-Language Pathologists Regarding Autism

Date: December 2010
Creator: Ray, Julie M.
Description: The increased prevalence rate of autism has immense implications for speech language pathologists (SLPs) who are directly involved in the education and service delivery for students with autism. However, few studies have documented the effectiveness of the knowledge and confidence of SLPs regarding autism. The purpose of this study was to measure the knowledge and confidence of SLPs regarding autism and the extent to which their educational and professional training prepared them to work effectively with this population. An online survey was administered to and returned by 336 SLPs nation-wide. Two multiple linear regressions were conducted to determine the variables that explained overall knowledge and confidence. The number of students with autism on one's caseload explained most of the variance. Independent sample t-test results depicted knowledge and confidence scores of SLPs who were behaviorally trained versus those who were not behaviorally trained. SLPs who were behaviorally trained had higher mean scores on measures of knowledge and confidence when compared to those without formal behavioral training. Finally, a bivariate correlation was conducted to explore the relationship between knowledge and confidence of SLPs, however, results were not statistically significant.

Knowledge and Training in Autism Spectrum Disorders Among Special Education Administrators.

Knowledge and Training in Autism Spectrum Disorders Among Special Education Administrators.

Date: December 2010
Creator: Hughes, Heather L.
Description: A significant rise in the number of students with autism spectrum disorders (ASD) served in today's schools requires special education administrators to possess knowledge in this area. The purpose of this study was to determine the general knowledge of special education administrators concerning ASD and knowledge of educational programming, to explore their educational training and professional development experiences in ASD, to identify the training needs of special education administrators in ASD, and to determine if knowledge, training and experience in ASD predict litigation. Using survey methods, data were collected from a sample of 106 special education administrators in Texas. Data revealed special education administrators were most knowledgeable of general characteristics, common myths, and instructional strategies, and less knowledgeable of eligibility criteria. Knowledge regarding educational programming for learners with ASD produced mixed results. Logistic regression analysis revealed general autism knowledge, knowledge of educational programming, training, and experience in ASD were not factors predicting litigation. Although results indicated none of the factors explored in this study were predictors of litigation, areas of need regarding professional development were identified. Implications for future research are also discussed.

Knowledge Discovery of Nanotube Mechanical Properties With an Informatics-Molecular Dynamics Approach

Knowledge Discovery of Nanotube Mechanical Properties With an Informatics-Molecular Dynamics Approach

Date: May 2012
Creator: Borders, Tammie L.
Description: Carbon nanotubes (CNT) have unparalleled mechanical properties, spanning several orders of magnitude over both length and time scales. Computational and experimental results vary greatly, partly due to the multitude of variables. Coupling physics-based molecular dynamics (MD) with informatics methodologies is proposed to navigate the large problem space. The adaptive intermolecular reactive empirical bond order (AIREBO) is used to model short range, long range and torsional interactions. A powerful approach that has not been used to study CNT mechanical properties is the derivation of descriptors and quantitative structure property relationships (QSPRs). For the study of defected single-walled CNTs (SWCNT), two descriptors were identified as critical: the density of non-sp2 hybridized carbons and the density of methyl groups functionalizing the surface. It is believed that both of these descriptors can be experimentally measured, paving the way for closed-loop computational-experimental development. Informatics can facilitate discovery of hidden knowledge. Further evaluation of the critical descriptors selected for Poisson’s ratio lead to the discovery that Poisson’s ratio has strain-varying nonlinear elastic behavior. CNT effectiveness in composites is based both on intrinsic mechanical properties and interfacial load transfer. In double-walled CNTs, inter-wall bonds are surface defects that decrease the intrinsic properties but also improve load transfer. ...

Knowledge Management and Law Enforcement: An Examination of Knowledge Management Strategies of the Police Information System (POLNET) in the Turkish National Police

Knowledge Management and Law Enforcement: An Examination of Knowledge Management Strategies of the Police Information System (POLNET) in the Turkish National Police

Date: August 2009
Creator: Gultekin, Kubra
Description: This research study explores knowledge management (KM) in law enforcement, focusing on the POLNET system established by the Turkish National Police as a knowledge-sharing tool. This study employs a qualitative case study for exploratory and descriptive purposes. The qualitative data set came from semi-structured face-to-face and telephone interviews, as well as self-administered e-mail questionnaires. The sample was composed of police administrators who created POLNET, working under the Department of Information Technologies and the Department of Communication. A content analysis method is used to analyze the data. This study finds that law enforcement organizations' KM strategies have several differences from Handzic and Zhou's integrated KM model. Especially, organizational culture and structure of law enforcement agencies differently affect knowledge creation, conversion, retrieval, and sharing processes. Accordingly, this study offers a new model which is dynamic and suggests that outcomes always affect drivers.

Knowledge management in times of change: Tacit and explicit knowledge transfers.

Knowledge management in times of change: Tacit and explicit knowledge transfers.

Date: December 2005
Creator: Hall, Heather Leigh
Description: This study proposed a look at the importance and challenges of knowledge management in times of great change. In order to understand the information phenomena of interest, impacts on knowledge workers and knowledge documents in times of great organizational change, the study is positioned in a major consolidation of state agencies in Texas. It pays special attention to how the changes were perceived by the knowledge workers by interviewing those that were impacted by the changes resulting from the reorganization. The overall goal is to assess knowledge management in times of great organizational change by analyzing the impact of consolidation on knowledge management in Texas's Health and Human Services agencies. The overarching research question is what happened to the knowledge management structure during this time of great change? The first research question was what was the knowledge worker environment during the time of change? The second research question was what was the knowledge management environment of the agencies during the time of change? The last research question was did consolidation of the HHS agencies diminish the ability to transition from tacit to explicit knowledge? Additionally, the study investigates how the bill that mandated the consolidation was covered in the local ...

Knowledge management in virtual organizations: A study of a best practices knowledge transfer model.

Knowledge management in virtual organizations: A study of a best practices knowledge transfer model.

Access: Use of this item is restricted to the UNT Community.
Date: May 2005
Creator: Berryman, Reba
Description: Knowledge management is a major concern for organizations today, and in spite of investments in technology, knowledge transfer remains problematic. This study sought to determine whether a relationship exists among participant group demographics (experience), implementation of an integrated knowledge transfer system (best practices model), knowledge transfer barriers, and knowledge transfer project (Web-based training) outcome in a virtual organization. The participant organization was a network of individuals and groups who practice patient advocacy in the research and treatment of cancer. These advocates volunteer in various capacities and are not collocated nor do they report to any single organizational entity. Volunteer participants were randomly assigned to a treatment or control condition. The treatment participants received a training supplement based upon a best practices knowledge transfer model. All participants reviewed a Web-based communications training module scheduled for deployment by the participant organization. Upon completion of the training program, participants were instructed to practice specific techniques from the program. At the end of this period, participants completed an online survey that measured demographics, perceived barriers to the knowledge transfer, and project outcome. Knowledge transfer barriers were defined as knowledge, source, recipient, and organizational context characteristics that inhibit the expected transfer. Project outcome was a ...

Knowledge-of-Correct-Response vs. Copying-of-Correct-Response: a Study of Discrimination Learning

Knowledge-of-Correct-Response vs. Copying-of-Correct-Response: a Study of Discrimination Learning

Date: August 1996
Creator: Geller, David, 1952-
Description: Copying prompts with subsequent unprompted practice produced better learning of simple discriminations than feedback only of a correct response without subsequent practice. The Copy condition promoted faster acquisition of accurate performance for all subjects, and shorter response latencies and durations for 3 of 4 subjects. The data support the findings of Barbetta, Heron, and Heward, 1993 as well as Drevno, Kimball, Possi, Heward, Garner III, and Barbetta, 1994. The author proposes that response repertoires are most valuable if easily reacquired at times after original learning. Thus, reacquisition performance data are emphasized. The data suggest that discriminations acquired by copying prompts may result in useful repertoires if a practice procedure is used which facilitates transfer of stimulus control from a formal prompt to a naturally occurring stimulus.

Knowledge-sharing Practices Among Turkish Peacekeeping Officers

Knowledge-sharing Practices Among Turkish Peacekeeping Officers

Date: August 2012
Creator: Eren, Murat Erkan
Description: The Turkish National Police (TNP) peacekeeping officers experience poor knowledge-sharing practices before, during, and after their tours of duty at the United Nations (UN) field missions, thus causing knowledge loss. The study aims to reveal the current knowledge-sharing practices of the TNP peacekeeping officers and proposes a knowledge-sharing system to share knowledge effectively. It also examines how applicable the knowledge management models are for their knowledge-sharing practices. In order to gain a better understanding about the knowledge-sharing practices of TNP officers, the researcher used a qualitative research method in this study. The researcher used semi-structured interviews in data collection. The participants were selected based on the non-probability and purposive sampling method. Content analysis and constant comparison was performed in the data analysis process. The most important knowledge sources of the peacekeeping officers are their colleagues, the Internet, and email groups. The peacekeepers recommend writing reports, organizing training programs, conducting exit interviews, adopting best practices, and creating a knowledge depository. The study uncovers that organizational culture, hierarchy, and physical proximity are significant factors that have a vital impact on knowledge sharing. Knowledge Conversion Model is substantially applicable for the knowledge-sharing practices of the TNP peacekeeping officer.

Knowledge synthesis in the biomedical literature: Nordihydroguaiaretic acid and breast cancer.

Knowledge synthesis in the biomedical literature: Nordihydroguaiaretic acid and breast cancer.

Date: December 2003
Creator: Sneed, Wanda A.
Description: This dissertation refines knowledge synthesis from publicly accessible databases, based on the model of D.R. Swanson. Knowledge synthesis endeavors bring together two or more non-interactive literatures to create combinatorial research data on a specific topic. In this endeavor the biomedical literature was searched on the anti-neoplastic agent nordihydroguaiaretic acid (NDGA) for its potential role as a functional food in the chemoprevention of breast cancer. Bibliometric cocitation was utilized to identify complementary but non-interactive literatures in the disciplines of biomedicine and dietary science. The continuing specialization and fragmentation of the cancer literature degenerates the potential usefulness of cross-disciplinary research and information. As the biomedical sciences become more specialized the potential increases for isolation of discoveries and for failures to connect science to the needs of the people. Within the information science discipline several techniques are available to bridge the isolation between discoveries recorded in different sets of literatures. Electronic database searching with combinatorial keyword entries, syllogistic modeling and bibliometric author cocitation analysis are the principle techniques applied in this endeavor. The research questions are addressed to the absence or presence of human in vivo research on breast cancer with the potentially chemopreventative functional food NDGA. Utilizing a syllogistic model the literatures ...
