In this phenomenological investigation, a qualitative approach to research methodology is utilized to explore the resiliency experiences of Black, Indigenous, people of color counselors in training (N = 12) at historically or predominantly White institutions. The participants represent multiple regions of the United States, spanning from the northeastern United States to the Pacific Northwest. Five themes were uncovered as a result of the interviews: (1) strategies for resiliency; (2) experiences with discrimination and oppression; (3) experiences of allyship and affirmation; (4) awareness of intersections and identity; and (5) call to action. I offer suggestions for ways to increase BIPOC student resiliency as well as increase student retention within counselor education programs and recommendations for creating nurturing and equitable classrooms to provide safety for marginalized students within counselor education programs.

The present study systematically reviewed and statistically summarized the current body of literature on the relationship between maternal health literacy and maternal sensitivity, and the effect of these two variables on mothers' care and decision making on distal attachment outcomes. In so doing, a systematic review of the extant peer-reviewed, published literature examining the effectiveness of interventions in effort to improve health literacy and maternal sensitivity, with a focus on increasing the quality of mother-preterm infant attachment outcomes, was undergone. This was followed by four multilevel random effects meta-analyses. Results indicated that mothers who participated in health literacy (maternal sensitivity) interventions had, on average, higher attachment quality, in comparison to those who did not participate. Additionally, maternal age was found to be a statistically significant predictor of the overall average effect size. This suggests that maternal health literacy may be a yet unexplored correlate of mother-preterm infant attachment outcomes.

Cyber physical systems (CPS) are an integration of computational and physical processes, where the cyber components monitor and control physical processes. Cyber-attacks largely target the cyber components with the intention of disrupting the functionality of the components in the physical domain. This dissertation explores the role of semantic inference in understanding such attacks and building resilient CPS systems. To that end, we present SIMON, an ontological design and verification framework that captures the intricate relationship(s) between cyber and physical components in CPS by leveraging several standard ontologies and extending the NIST CPS framework for the purpose of eliciting trustworthy requirements, assigning responsibilities and roles to CPS functionalities, and validating that the trustworthy requirements are met by the designed system. We demonstrate the capabilities of SIMON using two case studies – a vehicle to infrastructure (V2I) safety application and an additive manufacturing (AM) printer. In addition, we also present a taxonomy to capture threat feeds specific to the AM domain.

Due to inadequate long-term and large-scale observation approach for observation of soil moisture across the globe, this study intends to unveil the importance of using simulated soil moisture fields from land surface models, forced with observed precipitation and near-surface meteorology in monitoring drought and formulating effective water management practices for continued production irrigation applications. This study shows that socio-economic and ecosystem effects can be determined by evaluating spatial-temporal changes in irrigation applications. Thus, it facilitates understanding of the importance of water management and how water, energy, and carbon flows protect our climate and environment. By using Soil Moisture Active Passive (SMAP) in monitoring soil moisture, the information obtained is critical in providing early drought warnings, particularly in those parts of the United States that experience flash agricultural droughts. Further, this study highlights that frequent and reliable soil moisture measurements from SMAP helped improve the predictive capability of weather and climate models.

Legal rights for public employees are not clear in the area of social media speech. Following the Garcetti v Ceballos (2006) U.S. Supreme Court case, the pursuant to duty test was established. The social media speech of public employees, including educators, could be considered pursuant to their duties as an employee. This means that public employees are vulnerable to disciplinary action from their employer for social media speech. Furthermore, public employees are vulnerable even when they believe their social media speech is done as a private citizen. For this research study, 28 cases at the federal and state levels were analyzed. Seven of the examined cases were U.S. Supreme Court cases involving public employee speech rights. The other 21 cases were extracted from cases determined at the federal and state levels. The cases taking place after the Garcetti v Ceballos (2006) pursuant to duty test were analyzed to see how the test was applied to employee speech. Cases were also analyzed to see what other precedents from the courts had been applied. Additionally, private sector social media rights research was analyzed and reviewed to create more clarity for employees. The findings of the research show the courts have tested employee …

Empirical studies have shown that white racial attitudes tend to predict racial policy support. It has also been established that the relationship between whites' espoused racial tolerance and their support for ameliorative racial policies is imperfect, due to the principal-policy gap which characterized misalignment between individuals' espoused values for racial equity and their limited support for policies aimed at achieving those ends. Less consideration however, has been given to how the principal-policy gap changes over time. Using data from over 14,000 respondents who participated in the General Social Survey from 1994 through 2018, I show that the principal-policy gap is persistent, and that distances between principal and policy decline and expand over time. Using OLS regression models to analyze a sample of white adults, I find that the link between individuals' expressed liberal racial attitudes and their support for racial policies changed over the 24-year span. A noticeable narrowing of the principal-policy gap is also evident in the latter years of the sample. The reduction in the gap from 2014 through 2018 suggests that the influence of social movements like BLM may have been driving this trend.

The FeCo-V alloy, commercially referred to as Hiperco, is known for its great soft magnetic properties. However, the high cost of production has limited the usage of this alloy to small-scale applications, where the small volume and high magnetic performance are critical. Additive manufacturing (AM) has the potential to solve the production problems that exist in Hiperco manufacturing. The present research has focused on selective laser melting (SLM) based AM processing of Hiperco. The goal was to perform a detailed examination of SLM processed Hiperco and determine how the process parameters affect the microstructure, mechanical and magnetic properties. While a systematic set of SLM process parameters were employed, the results indicate that the energy density was quite similar for this set of process parameters, resulting in similar properties. Overall, the saturation magnetization (Ms) values were very good, but the coercivity (Hc) values were very high, in the case of all as SLM processed conditions. Additionally, a large variation in porosity was observed in the as SLM processed samples, as a function of process parameters. Interestingly, long-term heat-treatments of these samples in an Ar+H2 atmosphere resulted in substantial decreases in the Hc values. These results are presented and discussed.

‘Richte mich, Gott' exemplifies Jaakko Mäntyjärvi's pluralistic compositional approach through an interlaced organization of tonal and non-tonal pitch content. The development of ideas in the text of Psalm 43 and the concluding doxology is depicted across both layers of pitch organization and governed by specific structural pitch collections: (0145) and (0257). Moreover, the organic transformation of these structural pitch collections' intervallic content emerges as a fundamental means of progression throughout the work, in turn influencing the intervallic content of surrounding tonal material. This process of transformation and its relationship to the text is revealed through tonal and pitch-class analysis; a flexible approach to segmentation; and an exploration of two-way and three-way symmetry, and the disruption thereof, in pitch space and pitch-class space. An understanding of the interrelationship between pitch material from the tonal and non-tonal layers of pitch organization can aid singers, conductors, and analysts in the efficacy of their study, preparation, and performance of the psalm. The accompanying appendix of targeted choral warm-ups in this document offers choirs a practical method for studying, internalizing, and performing the non-tonal pitch content in the work.

The dissertation investigates the form of network governance in the context of U.S. homeless service networks (namely continuum of care programs; CoCs). This research examines CoC homeless service networks by applying the institutional collective action (ICA) perspectives to understand the forms of network governance as a reflection of network context. The ICA perspective has been applied to understand the rational behavior of network members for the network governance form to mitigate the collective action problems. The ICA perspective helps understand why network members accept specific governance structures with their expectation to maximize the benefits and minimize the costs and uncertainty in their process of collaboration. This dissertation uses the data of CoC networks and point in time data from the U.S. Department of Housing and Urban Development in 2019 and Census. The data developed for this study offers the homeless incidences, geographical characteristics, and governance structure based on the contact information. For an in-depth understanding, interview by CoC leaders was integrated. This dissertation consists of four essays about 1) Literature review on network governance and the theoretical argument in the ICA framework, 2) Background and network governance of the U.S. homeless service networks, 3) Factors affecting the choice of network …

The corrosion resistance under elevated temperature of additively manufactured 316L stainless steel made by directed energy deposition was studied. Test samples were prepared in a hybrid additive manufacturing machine using standard deposition parameters recommended by the manufacturer. Control samples were cut from wrought material to compare the results. The test was performed under a corrosive atmosphere with a solution of water with 3.5 % in weight of salt (NaCl). The total duration of the test was 635 hours, divided in five stages of 12, 24, 48, 226, and 325 hours to analyze the samples between each stage. The samples were analyzed quantitatively measuring weight loss and surface topography, and qualitatively by macroscopic inspection with digital photography, and microscopic inspection with optical and scanning electron microscopy. The results show a higher corrosion rate for the additively manufactured samples compared to the control samples. An evident increase in the size of pits initially present on the samples was observed and quantified on the additively manufactured. Although the additively manufactured samples were more aggressively attacked by corrosion, they still presented a shiny surface finish at the end of the test, reinforcing the idea of the formation of a passive oxide layer and suggesting …

Event-based mediated participatory archives, in which communities of ordinary people contribute their records to archives during collection day events represent a paradigm shift within the archival field. Applying a qualitative approach, this study investigates event-based mediated participatory archives using Bastian's communities of records and memory as a guiding framework. Using the Mass. Memories Road Show as a case study, data collection and analysis took place over three phases. In Phase I, archive supporting documents were collected and analyzed using "against the grain" historical analysis methods. In Phase II, data from the Mass. Memories Road Show digital collections were collected and analyzed using grounded theory analysis methods. In Phase III, ethnographic research data, including a direct observation and semi-structured interviews, was collected and analyzed using ethnographic analysis methods. The results of this study suggest that community participants' motivations to contribute to participatory archives are rooted in self-fulfillment while institutional archives personnel members' intentions are based in inclusive community-building. Furthermore, the contribution of records to the archives allows community participants to share personal stories that serve as evidence of their historical legacies and as affirmation of their roles in their communities. Throughout the findings, moments of connection which enable the sharing of …

The purpose of this qualitative multiple case study is to identify and describe the perceptions and experiences of lower elementary public-school teachers in the United States teaching with educational technologies during the COVID-19 pandemic. Through a demographic survey and semi-structured interviews, teachers shared their experiences regarding the barriers they encountered teaching and learning with educational technologies in face-to-face, remote, and hybrid classrooms. The multi-phase coding process used emic and etic codes to analyze the data. This study identifies and describes the existing barriers teachers face with learning technologies in the classroom before COVID-19 and the new obstacles they have encountered due to the pandemic. The results of this study are discussed, and recommendations are provided to help researchers identify the essential supports educators need for future emergencies.

Laser-based additive manufacturing offers a high degree of thermokinetic flexibility that has implications on the structure and properties of the fabricated component. However, to exploit the flexibility of this process, it is imperative to understand the process-inherent thermokinetic evolution and its effect on the material characteristics. In view of this, the present work establishes a fundamental understanding of the spatiotemporal variation of thermokinetics during the fabrication of the non-ferrous alloys using the laser powder bed fusion process. Due to existing limitations of experimental techniques to probe such thermokinetics, a finite element method-based computational model is developed to predict the thermokinetic variations during the process. With the computational approach coupled with experimental techniques, the current work presents the solidification behavior influenced by spatially varying thermokinetics. In addition, it uniquely predicts the process-inherent multi-track multi-layer evolution of thermal cycles as well as thermal stress cycles and identifies their influence on the post-solidification microstructural evolution involving solid-state phase transformation. Lastly, the response of the material with a unique microstructure is recorded under various conditions (static and dynamic), which is again compared with the same set properties obtained for the same material processed via conventional routes.

First, it builds upon existing literature by applying state-level arguments of third party involvement in mediation and peacekeeping efforts to the United Nations Security Council and regional IGOs. Second, it investigates the role of communication and coordination between third parties in their conflict management efforts.

Significant sub-systems were created and others enhanced providing a platform for an order of magnitude precision increase of the small 4He interval - 23P1→23P2 laser spectroscopy measurement, as well as other helium transitions. These measurements serve as tests of helium theory and quantum electro-dynamics in general. Many improvements to the original experiment are discussed and characterized. In particular, counting speed increased 10x, the signal level was doubled, a novel Doppler shift minimization technique was implemented, a control node re-architecture was realized along with many useful features, and the development environment was updated. An initial 28% precision improvement was achieved also providing a foundation for additional gain via a created smaller and more heavily windowed vacuum cavity and picomotor controls.

This study applies the knowledge, skills, and abilities (KSA) framework for eScience professionals to data service positions in academic libraries. Understanding the KSAs needed to provide data services is of crucial concern. The current study looks at KSAs of data professionals working in the United States academic libraries. An exploratory sequential mixed method design was adopted to discover the KSAs. The study was divided into two phases, a qualitative content analysis of 260 job advertisements for data professionals for Phase 1, and distribution of a self-administered online survey to data professionals working in academic libraries research data services (RDS) for Phase 2. The discovery of the KSAs from the content analysis of 260 job ads and the survey results from 167 data professionals were analyzed separately, and then Spearman rank order correlation was conducted in order to triangulate the data and compare results. The results from the study provide evidence on what hiring managers seek through job advertisements in terms of KSAs and which KSAs data professionals find to be important for working in RDS. The Spearman rank order correlation found strong agreement between job advertisement KSAs and data professionals perceptions of the KSAs.

The quality of workplace morale can positively and negatively affect employee engagement. Engaged employees are more likely to participate in active communication with one another. They are also more likely to adopt the organizational goals and work towards creating a productive work environment. Communication and engagement build trust. Established trust between employees and executive leadership is a delicate relationship to maintain, though it is necessary when contending with periods of stress. The organization profiled below experienced the stressor of needing to grow without alienating those afraid of change or used to operating in one predictable direction. There was a desire to generate engagement, build trust and make room for employee-directed change. This desire left the organization open to exploring its culture and its impact on employee engagement.

Multicomponent high-entropy and amorphous alloys represent relatively new classes of structural materials with complex atomic configurations and exceptional mechanical properties. However, there are several knowledge gaps in the relationships between their atomic structure and mechanical properties. Understanding these critical relationships will enable novel alloy design and tailoring of their mechanical properties for desired engineering applications. In this dissertation, first-principles calculations and molecular dynamics simulations are applied to investigate the local atomic configurations and ordering in high-entropy and amorphous alloys. Our findings suggest that fluctuations in local atomic configurations for high- entropy alloys result in significant changes in stacking fault energy, twin energy, dislocation behavior, dislocation-twin interactions, and critical shear stress. For amorphous alloys or metallic glasses, the short-range order (SRO) and medium-range order (MRO) were found to play decisive roles in determination of their mechanical properties. Structural relaxation was found to lead to shear localization, which was attributed to free volume change and evolution of SRO and MRO to more brittle nature. In contrast, rejuvenated metallic glasses had relatively large and uniform free volume distribution giving rise to homogeneous flow and increased plasticity.

Many academic institutions are tasked with trying to improve the usability of their online educational support technologies such as ePortfolios, intelligent websites, and other interface technology to make them as efficient as possible to meet the requirements of their end users. This is particularly important for the academic institutions during times and situations when they may not have a live human presence available to respond to various inquiries from their end users about the technology. The challenges of an academic institution in making its ePortfolios viable can cost itself, its end users, as well as its other stakeholders, money, time, and confidence in the technology. This study is about usability testing for improving the user-interface for ePortfolios. This is a qualitative study using the think-aloud protocol (TAP) for data collection and failure modes and effects analysis (FMEA) for data analysis.

Researchers of historic voice pedagogy texts have generally focused their objectives towards reviewing the recommendations of historic voice teachers pertaining to the physiological, acoustical, and musical elements of training singers; however, researchers have given less attention to the evidence of humanistic pedagogical elements presented by historic teachers of voice. This study aims to examine historic resources of vocal pedagogy for qualitative data representing exemplification of or advocacy for character strengths for voice teachers. Additionally, this study explores practical applications of character strengths within the context of the modern applied voice studio. In this context, character strengths are defined as the positive attributes of a personality that influence how a person thinks, feels, and behaves. In this document, historic pedagogical resources (N = 80) represent works published between 1811 and 1975. Using the scientifically validated VIA (Values-in-Action) Classification of Strengths, the relevant data extracted from these resources were categorized first into six virtues – wisdom, courage, humanity, justice, temperance, and transcendence. These data were further divided into the subcategories of character strengths based on descriptions located in seminal resources in character strengths research.
