Background: Recognition of the significance of psychological trauma and its impact on individuals, families, communities, and society at large has greatly expanded over the past 20 years, calling for the need to develop both trauma-sensitive and trauma–responsive services. Nurses, as direct care providers who work within a holistic perspective, are positioned to play an integral role in the advancement of ‘trauma-informed care’ within healthcare services. Objectives: The specific objectives of this thesis were: a) to describe the use of social media (Facebook and LinkedIn) in the recruitment of Registered Nurses for an online survey, and b) to explore and describe the understandings and experiences related to trauma and trauma-informed care among nurses that scored the highest on this scale. Method: This was a two-phase study design using mixed methods. Phase One consisted of an online quantitative self-report survey. Participants were recruited via social media with the aim of examining nurses’ attitudes related to trauma-informed care. Phase Two consisted of a qualitative study exploring nurses’ knowledge and experiences related to trauma-informed care. The studies were conducted using a sequential approach; that is, the target sample for Phase Two (qualitative study) was identified based on the results of the survey (Phase One). Findings: From the first phase of this research, I proposed that social media, and specifically Facebook and LinkedIn, offer suitable platforms for recruiting a diverse sample of Registered Nurses to complete an online survey. Associated advantages and challenges as well as specific differences between Facebook and LinkedIn as recruitment platforms should be considered when incorporating these strategies. Four main categories emerged from the second phase of the research: “(Not)Knowing Trauma-Informed Care”, “Conceptualizing Trauma and Trauma- Informed Care”, “Nursing Care in the Context of Trauma”, and “Dynamics of the Nurse-Patient Relationship in the Face of Trauma”. These findings highlight important considerations for trauma including, the complex dynamics of trauma that affect care, the importance of both knowing trauma as a concept, but also knowing how to act in response to trauma knowledge, the need to facilitate trauma-informed care beyond mental healthcare, and the parallels between nursing and trauma-informed care. Conclusion: This Master’s thesis has explored the use of a novel survey recruitment strategy as well as emphasized the need for nurses and organizations to incorporate trauma-informed principles in the services they provide, and in their cultures as a whole. This research reinforces that the discipline of nursing is aptly situated to apply tenets of trauma-informed care and that we must further the progression of trauma-informed care in practice, policy, education, and research.

The purpose of this study was to determine the effect of substrate levels and different types of substrates on population changes of mixed cultures of Serratia marcescens and Saccharomyces cerevisiae, as compared to pure cultures.

The desire to have enhanced and increased feature sets in embedded applications has contributed to a significant increase in the computational demands of such systems over the years. To support such demand and yet maintain reasonable power/energy budgets, the industry has begun a shift to multi-core architectures even in the embedded systems domain. Embedded real-time applications such as Avionics and Automotive systems are no exception to this trend. Such systems have strict certification requirements of subsets of their functionality, which result in strict temporal constraints on those subsets, while other subsets may have less strict requirements. Migrating such {\em mixed criticality} systems from single-core to multi-core platforms is challenging because application/component isolation and freedom from interference among them must be guaranteed. Safe and efficient, architecture-aware mapping and scheduling of system components (e.g., partitions, tasks, etc. as relevant to a particular domain) on the multiple cores is at the center of any scheme to migrate such systems from single-core to multi-core platforms. In this dissertation, we propose, develop and evaluate a unified framework to automate the mapping and scheduling process with the consideration of several architectural and application level requirements/constraints (e.g., communication and cache conflicts among system components, constraints prohibiting the allocation of certain system components on the same core, etc.)

With the increase in frequency of the use of mixed methods, both in research publications and in externally funded grants there are increasing calls for a set of standards to assess the quality of mixed methods research. The purpose of this mixed methods study was to conduct a multi-phase analysis to create a preliminary rubric to evaluate mixed methods research articles. This study included four research questions: 1. What are the common evaluation criteria found in the contemporary methodological literature pertaining to the design of mixed methods research? 2. What evaluation criteria do experts in the field of mixed methods research perceive as the most important when distinguishing top-quality research in mixed methods? 3. What differences are there in the outcome of the rubric for evaluating mixed methods research identified from the literature compared to those advocated most uniformly by a panel of mixed methods research experts? 4. What are disciplinary differences between the use of mixed methods and views about evaluating it, including the role of paradigms in mixed methods research? In the first phase of this multi-phase mixed methods study I used an inductive qualitative process to identify the quality criteria endorsed by 12 methodologists with a long-term involvement in mixed methods research. In the second phase of this study I conducted a quantitative analysis to pilot test a set of criteria identified in the qualitative phases. The sample for both phases of this study was comprised of the same eight males  and four females from multiple nationalities. Respondents to the on-line survey rated all 14 items as being important, with 11 of the 14 items being rated as very important or higher. When considered together, findings from the two phases of this study provide a interesting view of attitudes about the use and application of quality standards to the mixed methods literature. While there was agreement about what elements were important to evaluate, there was not an agreement about the idea that one set of standards could be applied to all mixed methods studies. / Ph. D.

Indiana University-Purdue University Indianapolis (IUPUI) / This study was undertaken to determine normal changes which occur over a period of approximately ten years, in occlusions determined to be excellent in the mixed dentition stage of development. Skeletal patterns were compared graphically with Downs' sample of patients with excellent occlusion. A model analysis was used to compare various aspects comprising an excellent occlusion. The data derived from the model analysis was subjected to a statistical analysis. The results showed a more protrusive facial profile with increase in age. Also, there was a decrease in overjet, cuspid occlusion became slightly more Class II, and there was an increase in the presence and amount of crowding in the lower anterior teeth.

Across the U.S., wildfires have become increasingly destructive and costly over the past few decades, with impacts particularly severe in the State of Florida. Because of an increase in wildfire frequency and severity and the number of people living in fire-prone areas the issue of wildfire risk management is of growing significance. One of the most important wildfire risk reduction tools is prescribed fire to reduce fuel loads, thereby reducing wildfire intensity and resulting damages. Because fire moves across a landscape and ownership boundaries, the spatial pattern of fuel load reduction may influence individual landowners' decisions about fire risk management on their own property. We develop and empirically test a spatial econometric model to study the interaction between Florida landowners in their wildfire risk management decisions. / Master of Science
