The transformational leader’s elements are known as the four I’s–idealized influence, intellectual stimulation, individualized consideration, and inspirational motivation, but research lacks the inclusion of trust. The assumption of trust in transformational leadership was never investigated through empirical research. The theoretical framework of this study was Fiedler’s (1973) contingency theory, Cummings and Bromiley (1996) definition of trust, Bass’s (1999) transformational leadership theory, Herzberg’s (1968/2008) Motivation-Hygiene Theory, and Sosik and Jung’s (2018) Full Range Leadership Development Model. The population selected was individuals serving in leadership roles that practiced transformational leadership. Probability sampling of 142 participants was utilized and involved random sampling that allowed robust statistical interference about the group. Statistically testing of all four research questions rejected/accepted each null hypotheses of trust and each of the four I’s of transformational leadership. However, transformational leaders can still achieve satisfaction, effectiveness, and effort that contribute to employee, team, and organizational outcomes with no significant correlation to trust. There were two limitations to the study. The first limitation consisted of 142 participants not having LinkedIn account accessibility through the Department of Defense. The second limitation was the coronavirus pandemic. Neither limitation impacted the study and perhaps enhanced the ability of the 142 participants to take the survey. Trust is not a matter of a different tool utilized by leaders. Trust is not about the tricks associated with gaining trust from followers or strategizing techniques by scholars and theorists. Trust is about character. Trust is about a readiness for an unguarded interaction.

Far from merely reinvigorating relativism, postmodernism has detected and expressed in our time a powerful nihilating process of which truth and reality itself are the final casualties; and with these morality and religion. Beginning from the theological reaches of philosophy, this book argues that gods played a crucial part in modern philosophy, even when it was most critical of them; that the dominant nihilism of Derrida is really an excessive and misleading outcome of a contemporary philosophy which could otherwise resonate with all that is best in our evolutionary image of the universe; that moralists who turn to art in order to overcome the fact–value version of this deadly dualism do not thereby rule out religion; and that a Christian theology which recognises the evolutionary and historical conditions of faith and revelation is once again producing a theology that builds upon the best of contemporary philosophy and science.

Physical processes that enhance heavy rainfall in association with warm season (April-September) fronts are investigated over western North Carolina. In this region of complex terrain encompassing the basins of the Upper Catawba River, the South Yadkin River, and the Upper Yadkin River, quantitative precipitation estimates and forecasts exhibit known biases, and a variety of large-scale atmospheric patterns can lead to heavy rainfall and flash flooding. The focus is on events with space-time dimensions on the meso-β scale (horizontally up to 200 km and temporally up to about 12–18 hours). The most frequent internally forced mesoscale weather features that produce such heavy rainfall episodes in the region are mid-latitude fronts. External mechanical forcing due to the orography of the southern Appalachians also plays an important role in shaping the rainfall intensity and distribution.A 17-year climatology comprised of 98 heavy rainfall cases is constructed using daily 4-km stage IV precipitation analyses. Cases are categorized according to the type of front (cold or stationary), front location (if stationary) relative to the study area (north, south, or over the basins), time of year (April and September vs. May–August), and time of day of peak rainfall. Classical warm front cases are too few to be included in this study. Results show that the majority of warm season heavy rainfall episodes tend to peak in the afternoon or evening, but there is a notable exception regarding events associated with stationary fronts located south of the basins. These episodes have a nocturnal maximum in rainfall in the foothills of the Blue Ridge Mountains, suggesting an interaction between the small-scale mountain-valley breezes and a mesoscale easterly low-level jet.The front type clusters are further evaluated utilizing the latest fifth-generation reanalysis (ERA5) produced by the European Centre for Medium-Range Weather Forecasts. Through the use of percentile rankings, the raw values of precipitable water and convective available potential energy are transformed into more meaningful and useful quantities that show well-defined maxima in and around the study region. For cold fronts as well as April and September cases of stationary fronts south of the basins, correlation analysis shows that the presence/strength of an atmospheric river plays a key role in determining the amount and areal extent of heavy rainfall. Also quantified is the low-level upslope flow, which helps regulate the spatial and temporal variability of heavy rainfall for nearly all frontal regimes in the study. In addition, rainfall events associated with stationary fronts to the north of the basins are heaviest when those fronts retreat farther north and west, coincident with a stronger Atlantic high pressure cell which increases the low-level moisture transport up the slopes of the Blue Ridge Mountains. For stationary fronts over the basins, the cases with the heaviest, most widespread rainfall are associated with a sharper west-east moisture gradient from the mountain ridges to the North Carolina Piedmont.

Curating knowledge from multiple siloed sources that contain both structured and unstructured data is a major challenge in many real-world applications. Pattern matching and querying represent fundamental tasks in modern data analytics that leverage this curated knowledge. The development of such applications necessitates overcoming several research challenges, including data extraction, named entity recognition, data modeling, and designing query interfaces. Moreover, the explainability of these functionalities is critical for their broader adoption. The emergence of Large Language Models (LLMs) has accelerated the development lifecycle of new capabilities. Nonetheless, there is an ongoing need for domain-specific tools tailored to user activities. The creation of digital assistants has gained considerable traction in recent years, with LLMs offering a promising avenue to develop such assistants utilizing domain-specific knowledge and assumptions. In this context, we introduce an advanced query and reasoning system, GraphAide, which constructs a knowledge graph (KG) from diverse sources and allows to query and reason over the resulting KG. GraphAide harnesses both the KG and LLMs to rapidly develop domain-specific digital assistants. It integrates design patterns from retrieval augmented generation (RAG) and the semantic web to create an agentic LLM application. GraphAide underscores the potential for streamlined and efficient development of specialized digital assistants, thereby enhancing their applicability across various domains.

The first part of this dissertation combines continuum limits of nonlocally interacting particles with stability analysis of nonlinear PDE to analyze the steady states of systems of pairwise-interacting particles. Models employing these assumptions cover a cornucopia of physical systems, from insect swarms and bacterial colonies to nanoparticle self-assembly. In this joint work with Theodore Kolokolnikov and Andrea Bertozzi, we study a continuum model with densities supported on co-dimension one curves for two-species particle interaction in two-dimensional Euclidean space, and apply linear stability analysis of concentric ring steady states to characterize the steady state patterns and instabilities which form. Conditions for linear well-posedness are determined and these results are compared to simulations of the discrete particle dynamics, showing predictive power of the linear theory. Part II continues the work on the compressive spectral method, which proposes the sparse Fourier domain approximation of solutions to multiscale PDE problems by soft thresholding. In this joint work with Hayden Schaeffer and Stanley Osher, we show that the method enjoys a number of desirable numerical and analytic properties, including convergence for linear PDE and a modified equation resulting from the sparse approximation. We also extend the method to solve elliptic equations and introduce sparse approximation of differential operators in the Fourier domain. The effectiveness of the method is demonstrated on homogenization examples, where its complexity is dependent only on the sparsity of the problem and constant in many cases.

Many real world networks are considered temporal networks, in which the chronological ordering of the edges has importance to the meaning of the data. Performing temporal subgraph matching on such graphs requires the edges in the subgraphs to match the order of the temporal graph motif we are searching for. Previous methods for solving this rely on the use of static subgraph matching to find potential matches first, before filtering them based on edge order to find the true temporal matches. We present a new algorithm for temporal subgraph isomorphism that performs the subgraph matching directly on the chronologically sorted edges. By restricting our search to only the subgraphs with chronologically correct edges, we can improve the performance of the algorithm significantly. We present experimental timing results to show significant performance improvements on publicly available datasets for a number of different temporal query graph motifs with four or more nodes. We also demonstrate a practical example of how temporal subgraph isomorphism can produce more meaningful results than traditional static subgraph searches.

Given a query graph that represents a pattern of interest, the emerging pattern detection problem can be viewed as a continuous query problem on a dynamic graph. We present an incremental algorithm for continuous query processing on dynamic graphs. The algorithm is based on the concept of query decomposition; we decompose a query graph into smaller subgraphs and assemble the result of sub-queries to find complete matches with the specified query. The novelty of our work lies in using the subgraph distributional statistics collected from the dynamic graph to generate the decomposition. We introduce a \"Lazy Search\" algorithm where the search strategy is decided on a vertex-to-vertex basis depending on the likelihood of a match in the vertex neighborhood. We also propose a metric named \"Relative Selectivity\" that is used to select between different query decomposition strategies. Our experiments performed on real online news, network traffic stream and a synthetic social network benchmark demonstrate 10-100x speedups over competing approaches.

This dissertation argues that writing the web is a process of interactivity among participants through a collaborative interface of word, image, and sound. The Web is discussed in this project as a hybrid medium for writing in various forms. This interactive environment is also theorized as a medium for the production of original student projects in collaboration with other authors. As such, we need to re-think our understanding of writing beyond print, text, and hypertext, to account for the visual, aural, virtual, and interactive elements of the Web. This critical inquiry into the pedagogical aspect of digital media is examined through five inter-related frameworks: interfacing, orality, visuality, virtuality, and textuality. This project takes an interdisciplinary approach that explores prior precedents in multimedia and virtual reality in twentieth century collage on paper and canvas. Nineteenth century developments in photography will also be examined. For instance, the diorama and daguerreotype are discussed as nascent virtual realities that challenged cultural expectations concerning the nature of representation and truth. These early artistic and technological developments are examined within a contemporary context of the World Wide Web, which is theorized as a collage-like fictive space for composition. This dissertation examines web based multimedia in detail including several examples of Internet Art featured in the Whitney Biennial 2000. While this digital medium is unique and innovative, the component parts of the Web can be better understood in relation to a history of oral tradition, literature, print, painting, photography, and technologies of code, such as the telegraph. This is an important perspective to consider as we utilize web-based multimedia, networked hypertext, and virtual reality interfaces in education. Technology continues to be a major force in educational environments, yet teachers often struggle with how to effectively teach with new media in ways to support writing and literacy. We gain insights about how to write with and teach with this medium by avoiding uncritical assumptions concerning the expectations of technology to automatically resolve pedagogical issues. While this project takes a theoretical and historical approach to these issues, the central concern of this dissertation relates to the role of teachers in this writing process.

Your article \" `Boss' Tickets Come - and Go\" {March 13}presented an accurate picture of the excitement of ticket sales forBruce Springsteen's upcoming concerts at the Nassau Coliseum as well as the widespread disappointment of the many who did not get tickets. However, the article failed to recognize that despite some effort towards fair distribution of tickets, professional ticket scalpers still managed to walk away with a substantial number of the limited tickets. The four-ticket limit certainly helped spread tickets around, but the numbered wristbands often served to facilitate, rather than prevent, scalpers cutting the lines.
