Show moreThe Community of Inquiry model provides a framework for recognizing and evaluating interpersonal behaviors in online educational settings. One of its three components, teaching presence (TP), describes those behaviors that are under the auspices of the online instructor. By examining these interactions and behaviors through the theoretical lens provided by teaching presence, and by measuring them with the Teaching Presence Scale (TPS), it may be possible to gain greater understanding of the practices employed most effectively by online instructors. This dissertation describes the background, theoretical and empirical foundations, methods, and results of a study on TP. The purpose of the study was threefold: to validate the use of the TPS in an online professional development setting outside of the higher education context in which it was designed and tested; to confirm the factor composition of TP among facilitators in an online professional development course; and to determine the extent and direction of the relationship between teaching presence and student satisfaction. The participants in this study (n = 718) were in-service educators enrolled at the Florida Online Reading Professional Development program. They responded to an instrument that included the 28 original TPS questions, plus 17 student satisfaction and 11 demographic items. Confirmatory factor analysis and Pearson's correlation were used to answer the three research questions and corresponding hypotheses. The research questions were answered in the affirmative, and the null hypotheses rejected. There was support for the use of the TPS in an online professional development setting (all 28 TPS items loaded as hypothesized on the three TP factors); support for a three-factor model of TP using 17 of the 28 TPS items (X2 [116, N = 718] = 115.56, p = .49, CFI = .999; NNFI = .999; SRMR = .02; and RMSEA = .03); and evidence of a strong relationship between components of TP and student satisfaction (statistically significant correlations [p < .001] between TP and student satisfaction, r2 values ranging from .25 to .57). A discussion of the results, implications for practice, implications for further research, and limitations of the study were presented following the data analysis.

Over the past decade, many studies have provided some understanding on what influences association members' decision to attend a meeting; however, more systematic and theoretical research is necessary. The decision making process of attendees is a complicated human behavior practice.

Show moreOver the past decade, many studies have provided some understanding on what influences association members' decision to attend a meeting; however, more systematic and theoretical research is necessary. The decision making process of attendees is a complicated human behavior practice. The major contribution of this study is adopting the sense of community (SOC) model from psychology to gain a better understanding of the attendee behavior. By doing so, this study will add a theoretical foundation to the existing research in the meeting industry. Also, this study will contribute to the SOC research in psychology by applying the concept to a different setting. This study investigates whether annual conferences build a SOC among association members. First, the SOC of association members at the conference will be analyzed. Second, the influence of SOC on members' satisfaction with the conference will be studied. Lastly, the direct and indirect relationship between SOC and future intentions (i.e., return to next meeting, membership renewal, and membership recommendation) will be examined. Data was collected through an intercept survey approach at three annual conferences of national/international associations. The questionnaire consisted of four sections: sense of community, satisfaction with the conference, future intentions, and member profile. Confirmatory factor analysis was conducted to test the factor structure and structural equation modeling was used to examine the relationships, and Spearman's rank order correlation was used to see the strength of the relationship between respondent characteristics and sense of community. The results showed that sense of community was a strong predictor of future intentions. Implications, limitations, and suggestions for future research are discussed in the final chapter.

Show moreLittle is known about the variation in digital forensics practice in the United States as adopted by large local police agencies. This study investigated how environmental constraints, contextual factors, organizational complexity, and organizational control relate to the adoption of digital forensics practice. This study integrated 3 theoretical perspectives in organizational studies to guide the analysis of the relations: institutional theory, contingency theory, and adoption-of-innovation theory. Institutional theory was used to analyze the impact of environmental constraints on the adoption of innovation, and contingency theory was used to examine the impacts of organizational control on the adoption of innovation. Adoption of innovation theory was employed to describe the degree to which digital forensics practice has been adopted by large municipal police agencies having 100 or more sworn police officers.The data set was assembled primarily by using Law Enforcement Management and Administrative Statistics (LEMAS) 2003 and 1999. Dr. Edward Maguire`s survey was used to obtain 1 variable. The joining up of the data set to construct the sample resulted in 345 large local police agencies. The descriptive results on the degree of adoption of digital forensics practice indicate that 37.7% of large local police agencies have dedicated personnel to address digital evidence, 32.8% of police agencies address digital evidence but do not have dedicated personnel, and only 24.3% of police agencies have a specialized unit with full-time personnel to address digital evidence. About 5% of local police agencies do nothing to address digital evidence in any circumstance. These descriptive statistics indicate that digital evidence is a matter of concern for most large local police agencies and that they respond to varying degrees to digital evidence at the organizational level. Agencies that have not adopted digital forensics practice are in the minority. The structural equation model was used to test the hypothesized relations, easing the rigorous analysis of relations between latent constructs and several indicator variables. Environmental constraints have the largest impact on the adoption of innovation, exerting a positive influence. No statistically significant relation was found between organizational control and adoption of digital forensic practice. Contextual factors (task scope and personnel size) positively influence the adoption of digital forensics. Structural control factors, including administrative weight and formalization, have no significant influence on the adoption of innovation. The conclusions of the study are as follows. Police agencies adopt digital forensics practice primarily by relying on environmental constraints. Police agencies exposed to higher environmental constraints are more frequently expected to adopt digital forensics practice. Because organizational control of police agencies is not significantly related to digital forensics practice adoption, police agencies do not take their organizational control extensively into consideration when they consider adopting digital forensics practice. The positive influence of task scope and size on digital forensics practice adoption was expected. The extent of task scope and the number of personnel indicate a higher capacity for police agencies to adopt digital forensics practice. Administrative weight and formalization do not influence the adoption of digital forensics practice. Therefore, structural control and coordination are not important for large local police agencies to adopt digital forensics practice.The results of the study indicate that the adoption of digital forensics practice is based primarily on environmental constraints. Therefore, more drastic impacts on digital forensics practice should be expected from local police agencies' environments than from internal organizational factors. Researchers investigating the influence of various factors on the adoption of digital forensics practice should further examine environmental variables. The unexpected results concerning the impact of administrative weight and formalization should be researched with broader considerations.

Show moreThe current study takes an initial step toward deriving a method for empirically based, theory-driven treatment matching in a military population suffering from PTSD. Along with the more overt symptoms of PTSD (e.g., persistent hyperarousal), secondary cognitive symptoms have also been shown to be significantly associated with avoidance and intrusive symptoms, as well as contribute to functional impairment. Based on the factor analytic and treatment literature for PTSD, it appears that there are two central mechanisms associated with beneficial therapeutic change that underlies both CPT and PE treatments (i.e., habituation, changes in cognitions). Additionally, different traumatic events and peritraumatic responses may be associated with unique symptom profiles and may necessitate targeted treatment. The present study proposes a novel approach to treatment matching based on the factor structure of PTSD and underlying mechanisms of treatment response. More broadly, this paper provides evidence for a broader understanding of peritraumatic responses and the potential implications of these responses for symptom profiles and illness trajectories.

Show moreSystems engineering is a methodical multi-disciplinary approach to design, build, and operate complex systems. Launch vehicles are considered by many extremely complex systems that have greatly impacted where the systems engineering industry is today. Launch vehicles are used to transport payloads from the ground to a location in space. Satellites launched by launch vehicles can range from commercial communications to national security payloads. Satellite costs can range from a few million dollars to billions of dollars. Prior research suggests that lack of systems engineering rigor as one of the leading contributors to launch vehicle failures. A launch vehicle failure could have economic, societal, scientific, and national security impacts. This is why it is critical to understand the factors that affect systems engineering rigor in U.S. launch vehicle organizations.The current research examined organizational factors that influence systems engineering rigor in launch vehicle organizations. This study examined the effects of the factors of systems engineering culture and systems engineering support on systems engineering rigor. Particularly, the effects of top management support, organizational commitment, systems engineering support, and value of systems engineering were examined. This research study also analyzed the mediating role of systems engineering support between top management support and systems engineering rigor, as well as between organizational commitment and systems engineering rigor. A quantitative approach was used for this. Data for the study was collected via survey instrument. A total of 203 people in various systems engineering roles in launch vehicle organizations throughout the United States voluntarily participated. Each latent construct of the study was validated using confirmatory factor analysis (CFA). Structural equation modeling (SEM) was used to examine the relationships between the variables of the study. The IBM SPSS Amos 25 software was used to analyze the CFA and SEM.
