Analyzing the Principal Perspective to Lead the Implementation of Learning Technologies in Public Schools: A Multi-Strategy Study (open access)

Analyzing the Principal Perspective to Lead the Implementation of Learning Technologies in Public Schools: A Multi-Strategy Study

As technologies for learning become increasingly available in K-12 schools, the role and responsibilities of campus principals continue to evolve. Incorporating technologies in schools requires shifts in practices, the development of new skills, and in some cases, changes in the mindset of stakeholders. Schools should be capable of absorbing the knowledge and creating the systemic structures required for the implementation ICTs. The purpose of this study was to research the principals' perspective to lead the implementation of ICTs for learning in public schools. As campus leaders, principals are increasingly required to support the utilization of ICTs for classroom instruction. It is of particular importance, therefore, to study and explore the needs school principals identify to lead the implementation of technologies for learning. More specifically, the goal was to gather relevant data to analyze topics that campus principals believe positively and negatively influence the implementation of ICTs in schools.

An Artificial Intelligence-Driven Model-Based Analysis of System Requirements for Exposing Off-Nominal Behaviors (open access)

An Artificial Intelligence-Driven Model-Based Analysis of System Requirements for Exposing Off-Nominal Behaviors

With the advent of autonomous systems and deep learning systems, safety pertaining to these systems has become a major concern. The existing failure analysis techniques are not enough to thoroughly analyze the safety in these systems. Moreover, because these systems are created to operate in various conditions, they are susceptible to unknown safety issues. Hence, we need mechanisms which can take into account the complexity of operational design domains, identify safety issues other than failures, and expose unknown safety issues. Moreover, existing safety analysis approaches require a lot of effort and time for analysis and do not consider machine learning (ML) safety. To address these limitations, in this dissertation, we discuss an artificial-intelligence driven model-based methodology that aids in identifying unknown safety issues and analyzing ML safety. Our methodology consists of 4 major tasks: 1) automated model generation, 2) automated analysis of component state transition model specification, 3) undesired states analysis, and 4) causal factor analysis. In our methodology we identify unknown safety issues by finding undesired combinations of components' states and environmental entities' states as well as causes resulting in these undesired combinations. In our methodology, we refer to the behaviors that occur because of undesired combinations as off-nominal …

Artificial Intelligence Teammates in a Collaborative Information Seeking Environment from the Perspective of Women Engineers in the United States (open access)

Artificial Intelligence Teammates in a Collaborative Information Seeking Environment from the Perspective of Women Engineers in the United States

The purpose of this study was to collect design requirements from women engineers on artificial intelligence teammates such as Microsoft Teams, Slack, and Trello. A mixed methods research design was used for this study with an online survey and semi-structure interviews. The study results revealed design requirements from women engineers including solutions to sociotechnical issues that could arise from artificial intelligence teammates in the workplace. The results showed various ways women engineers collaborate in the workplace with and without artificial intelligence. Additionally, women engineers' attitude towards artificial intelligence was examined to identify if there was a correlation to self-efficacy. This research study fills a previous study gap that solicited design requirements from research scientists, by soliciting practitioners. Practitioners such as women engineers are underrepresented in the workplace, and they could benefit from an artificial intelligence teammate with their design requirements. Finally, this study contributes to the information science literature on collaborative information seeking, artificial intelligence design, and engineers' information seeking behaviors.

At the Junction of Dissemination and Implementation: Facilitating Access to Behavior Analytic Research (open access)

At the Junction of Dissemination and Implementation: Facilitating Access to Behavior Analytic Research

Research in scholarly communication is usually limited to the use and dissemination of scientific material by scholars. This excludes the transfer of knowledge from research producers to service providers. Some may argue the primary function of science is to investigate the conditions in the lab so everyday interactions with the environment are more effective and efficient. This is the underlying philosophy of the science of behavior analysis. Comprised of a basic science, an applied science and a philosophy the field of behavior analysis relies on research developments to inform effective practice. Guided by dissemination processes studied in information science, this investigation revealed the content layer in behavior analysis is primarily comprised of journal articles. Ninety four percent of the research artifacts cited in the current content layer are from journal articles. Other dissemination channels used to develop the behavior analytic content layer included scientific magazine articles, oral reports, dissertations and theses, and unpublished manuscripts. The information use environment for professionals in this field is very different than that of the scholars; most professionals do not have access to a university library. Therefore, the research producers are disseminating developments via communication channels some service providers cannot access. This investigation reveals the …

Attachment to God: Pathways to Resilience and Posttraumatic Growth (open access)

Attachment to God: Pathways to Resilience and Posttraumatic Growth

Having a secure attachment to God may act as a buffer against stress. Secure attachment to God has been positively associated with adaptive outcomes following stress, such as higher levels of stress-related growth and fewer maladaptive symptoms including depression, prolonged grief, and traumatic distress. However, relatively few studies have empirically tested the relationship between attachment to God and resilience and posttraumatic growth. Thus, the current study explored the potential associations and pathways through which attachment to God is associated with resilience and posttraumatic growth in a sample of 303 suddenly and/or traumatically bereaved individuals. The current study found that (a) God attachment avoidance is a unique negative predictor of resilience and posttraumatic growth even when controlling for adult attachment, (b) self-compassion and meaning-making mediate the association between God attachment anxiety and resilience/posttraumatic growth, (c) secure attachment to God is associated with higher levels of resilience than insecure attachment styles, but not with posttraumatic growth, and (d) an increased number of secondary losses is associated with lower levels of resilience. I conclude by discussing my findings in light of the extant literature on attachment to God, resilience, and posttraumatic growth. By better understanding attachment to God and how it may relate …

The Balkan Imbroglio: The Diplomatic, Military, and Political Origins of the Macedonian Campaign of World War I

The Macedonian Campaign of World War I (October 1915-November 1918) traditionally remains one of the understudied theatres of the historiography of the conflict. Despite its vital importance in the outcome of the war, it is still considered as a mere sideshow compared to the Western Front and the Gallipoli Campaign. This dissertation presents a much-needed re-evaluation of the Macedonian Campaign's diplomatic and political origins within the war's early context. In doing so, this study first concentrates on a longue durée perspective and assesses the main historical events in the Balkans and Central Europe from the end of the French Revolution to World War I. In a perspective running throughout the entire nineteenth century, this dissertation integrates the importance of nascent nationalism in the Balkans and examine the Austro-Hungarian Empire's steady decline and subsequent diplomatic realignment toward the Balkans. Similarly, this work depicts the intense power struggle in Southeastern Europe between some of this story's main protagonists, namely the Austro-Hungarian, Russian and Ottoman Empires. This dissertation also evaluates the rise of new regional powers such as Bulgaria and Serbia and examines their connection to the European balance of power and general diplomatic equilibrium. In the first half of this dissertation, I …

Carbon Capture Utilization for Bio-Based Building Insulation Foams

Ecological, health and environmental concerns are driving the need for bio-resourced foams for the building industry and for other applications. This is because insulation is one of the most important aspects of the building envelope. Global building insulation is expected to reach USD 27.74 billion in 2022. Conventional insulation materials currently used in buildings are made from nonrenewable products (petroleum, fiber glass). However, they yield increasing unrecyclable eco-unfriendly waste at the end of their lives; styrene and polyurethane generates over 100,000 kg of waste insulation in US alone yearly. This is because they are non-biodegradable and can remain as microplastics in the environment for 1000 years. Polyurethane contains the same amount of energy as coal. Additionally, most of the processing techniques and blowing agents used in this manufacturing of these foams are cancerous and injurious to health when inhaled. Because buildings and their construction together account for 36% of global energy use and 39% of energy-related carbon dioxide emissions annually, there is a need to develop eco-friendly foams that will serve as possible substitutes to the currently used petroleum-based foams. This dissertation examined the development and characterization of eco-friendly foams that were developed using the melt mixing technique of bio-resourced …
