In this work, we leverage the recent developments in computer science to address several of the challenges in current literature-based discovery (LBD) solutions. First, LBD solutions cannot use semantics or are too computational complex. To solve the problems we propose a generative model OverlapLDA based on topic modeling, which has been shown both effective and efficient in extracting semantics from a corpus. We also introduce an inference method of OverlapLDA. We conduct extensive experiments to show the effectiveness and efficiency of OverlapLDA in LBD. Second, we expand LBD to a more complex and realistic setting. The settings are that there can be more than one concept connecting the input concepts, and the connectivity pattern between concepts can also be more complex than a chain. Current LBD solutions can hardly complete the LBD task in the new setting. We simplify the hypotheses as concept sets and propose LBDSetNet based on graph neural networks to solve this problem. We also introduce different training schemes based on self-supervised learning to train LBDSetNet without relying on comprehensive labeled hypotheses that are extremely costly to get. Our comprehensive experiments show that LBDSetNet outperforms strong baselines on simple hypotheses and addresses complex hypotheses.

Life coaching is a rapidly expanding industry that focuses on client development, enhancement of life experience, and goal attainment often when clients are experiencing personal, professional, and social change. Online communities of practice (CoPs) provide opportunity for individuals to connect, share experiences, and learn from each other under the auspices of a unifying theme or subject. Since the 1990s, CoPs have spread from education to other areas of business and industry and continue to shape participant professional development. However, the everyday life information seeking and practices of life coaches remains unexplored within information science literature from the perspectives of life coach engagement in seeking information, life coach engagement in CoPs, and life coach interactions with other coaches. The purpose of this research study was to explore life coach perspectives of coaching, the diverse information needs of life coaches, the types and strength of relationships between life coaches and CoPs, the role of coaching certification and/or licensing as contributing to the professionalization of life coaching, and the means of communication exchange by life coaches through information communication technologies. This mixed method study focused on life coaches who self-identify as belonging to a CoP and those that do not. Theoretical frameworks for …

This study will extend the current body of knowledge about how accessible and affordable information communication technologies (ICT; smartphones, tablets, and computers) can foster social interaction and reduce social isolation and loneliness in older adults aged 55 plus. The first study is a systematic literature review of existing studies on ICT and the willingness of older adults to use technology. The second study is quantitative research that investigates the trust and reasoning of older adults using ICT, like smartphones, tablets, and computers that foster social interaction and the level of technological ownership. The second study is conducted using research data through surveys conducted by Pew Research Center on behalf of Princeton University. Finally, the third study explores the level of ownership of technology and methods to reduce social isolation using ICT. The effectiveness of smartphones, tablets, and computers that foster social interaction were reviewed to create a sense of community to reduce social isolation.

In the wake of a disturbing decades-long trend in both print and visual media—the appropriation of Black history and culture—another trend is observed in works of African American fiction: the reclamation of the appropriated imagery, in both neo-slave narratives and works of Afrofuturism. The image focused on specifically in this paper is that of the ship, which I argue serves at least two identifiable functions in Black fiction: first, to address the historical treatment of Africans and their American descendants, and secondly, to demonstrate Black progress and potential. Through an exploration of three works of African American fiction, works that take their Black protagonists beyond the ship's dreadful hold, the reader can see the important themes being channeled: Charles Johnson's Middle Passage sets a course on how to arrive at true freedom, enacting a process of Black liberation that begins with learning how to survive "in the wake," a concept derived Christina Sharpe's work In the Wake: On Blackness and Being. Rivers Solomon's An Unkindness of Ghosts demonstrates not only the effects of "the hold," but how the hold itself has evolved from its origins on the slave ship; as new holds are constructed and demanded by society, rebellion is …

Libraries can have a significant impact on today's students and the schools of today and tomorrow. The way students learn is changing as technology changes: rapidly. The knowledge and skills that today's librarians carry can influence the students immensely, including their use of technology. However, with many districts suffering budget cuts, one of the first positions to cut is the certified librarian, replaced by a library paraprofessional. These budget cuts will impact what the libraries can offer students. It is vital that districts support their library program and the person in charge, whether a paraprofessional or certified librarian, to positively impact the students for their future. The purpose of this study was to explore the effectiveness of library programs within a technology-rich school district that utilizes paraprofessionals supported by a certified librarian.

Music binder's volumes, or collections of sheet music typically bound by women in the nineteenth century, constitute an informative and underutilized set of historical artifacts. Each binder's volume can be viewed as a Spotify playlist frozen in time. An individual volume contains more than just the volume's individual pieces; it also holds the marginalia, the choices women made on what to include in a binder, and information on where and how music was produced. This dissertation examines music binder's volumes quantitatively, processing information found in binder's volumes by using the MARC and other cataloguing data to construct a relational database. I engage with broad questions of music publishing and consumption and provide a method to contextualize qualitative results on a larger scale. In doing so, I make two distinct contributions to music research and the digital humanities. First, this project offers a clear path for engaging with music binder's volumes and material history of nineteenth-century America in ways that scholars have rarely engaged in prior to this point. I highlight how data analysis provides new framings for binder's volumes and for sheet music consumption both at the song-level and at larger levels of the data. Second, and more broadly, this …

This dissertation examines representations of the Pacific theater in World War II in ethnic American literature, with a focus on its rendition of US and Japanese racism and imperialism in the mid-twentieth century. Reading a range of African, Asian, Jewish, Mexican, and Native American literary writings, I investigate their modifications of the American master narrative that the Second World War was "good" and "necessary," a war fought against fascism and for democracy, justice, and freedom. Instead of such a simplistic and reductive view, ethnic American writers envision the Pacific theater as a race war between whites and persons of color and as a conflict between two imperialist nations, the United States and Japan. Ethnic Americans' racial double consciousness functions to resist an oversimplification of the Pacific theater. In these ethnic writers' work, American characters from diverse backgrounds create friendships with those of Asian nationalities, including Chinese, Filipinos, Koreans, and Japanese. These texts are necessary because ethnic Americans' experiences are underrepresented in the traditional WWII narrative of Western masculinity, originated by Ernest Hemingway and completed by President Truman and Douglas MacArthur. As opposed to the typical white American literary and cinematic treatment of the war as fought in the land of …

In this thesis, I explore strategies used by the local timber industry to influence forest policy on the Black Hills National Forest. These strategies include leveraging political pressure, proposing alternative interpretations of existing laws, and first requesting and then rejecting scientific data. Discursive strategies used by the timber industry to influence US Forest Service policy are compared and contrasted with those used by the environmental movement. The paper explores when and why stakeholders use different discursive strategies to influence forest policy.

This study focuses on the discourse that orders and creates a logic of the extraterrestrial during postmodernity, what I term "Fringe." Using Foucault's notion of discourse, I define and theorize Fringe and its formation during postmodernity, looking at the particular features of the historical moment post-1960 that contributed to the creation and regulation of a particular extraterrestrial. I then investigate historical conceptions of the extraterrestrial from Aquinas to Kant. This genealogy of the extraterrestrial reveals a rich history of the extraterrestrial and compares this history with Fringe. After this I discuss two precursors of Fringe discourse: the Society for Psychical Research and the writings of anomalous researcher Charles Fort. This investigation of pre-Fringe notions of the psychical in discourse shows how the SPR and Fort's work both created new ways of looking at and speaking about phenomena falling outside the purview of "normal science" and contributed to the formation of Fringe while also being distinguishable from it. Finally, I analyze two popular iterations of Fringe discourse—the ancient aliens hypothesis and the abduction narrative—as popularized in the works of Erich von Däniken and Whitley Strieber.

This report discusses the future of academic libraries which serve as an essential gateway to knowledge. It discusses how libraries, as one of the largest facilities on campus, have become vibrant hubs for diverse purposes while retaining flexibility for future needs. How librarians have been steering discussions about open-source journals and courseware, which has profound implications for student access and success, and institutional budgets. Why libraries are leveraging special collections to carve out niches for their institutions and bolster connections with students and the local community. What librarians are saying about how varied their jobs have become, and how the profession is – and isn’t – diversifying. How librarians have adapted to automation to learn new technical, legal, and interpersonal skills.

Current events and social movements aimed at bringing awareness to oppressed groups have reminded us that the United States has still not achieved justice and equality for all. Social and political tensions have become inescapable in our increasingly connected world. Therefore, students need to learn about diverse ways of knowing and being in a pluralistic society. Since publishing and education companies compete for business, the amount of digital and print resources available to teachers can be overwhelming. Because a vital component of a multicultural education includes diverse materials that authentically portray views and experiences from a wide range of cultures, traditions, and values, it is necessary to critically analyze the curricular content that teachers are expected to use in their classrooms. The purpose of this study is to analyze the literature that is included in district-approved book lists for public schools to determine how these texts support the principles of multiculturalism and multicultural education in sixth-grade classrooms. The tenets of critical multicultural analysis (CMA) guided this critical content analysis. Because teachers in these districts are limited to choosing books from approved lists to read with their students, the texts for this study were selected from approved literature lists that were …

The goal of this work is to improve the robustness and generalization of deep learning models, using a similar approach to the unsupervised "innate learning" strategy in visual development. A series of research studies are presented to demonstrate how an unsupervised machine learning efficient coding approach can create filters similar to the receptive fields of the primary visual cortex (V1) in the brain, and these filters are capable of pretraining convolutional neural networks (CNNs) to enable faster training times and higher accuracy with less dependency on the source data. Independent component analysis (ICA) is used for unsupervised feature extraction as it has shown success in both applied machine learning and modeling biological neural receptive fields. This pretraining applies equally well to various forms of visual input, including natural color images, black and white, binocular, and video to drive the V1-like Gabor filters in the brain. For efficient processing of typical visual scenes, the filters that ICA produces are developed by encoding natural images. These filters are then used to initialize the kernels in the first layer of a CNN to train on the CIFAR-10 dataset to perform image classification. Results show that the ICA initialization for a custom made CNN …

This study aims to apply user reviews and numerical ratings toward items to create an aspect-aware high-order representation for a recommendation system. We propose a novel aspect-aware knowledge graph recommendation model (AKGR) with the deep learning method to predict users' ratings on non-interacted items, from which more personalized recommendations can be made. First, we create a sequence-to-sequence encoder and decoder model by exploiting contextual and syntactic information in user reviews to extract aspects critical to items. Then we utilize the principal component analysis (PCA) and the K-means clustering to analyze the extracted aspects for category classification. Based on the aspects, we construct a graph structure to connect users and items which share the same aspect-based opinions for mining user preferences and item attributes. Finally, we combine the user and item latent features from the reviews and the user-item rating matrix to complete the rating prediction task by applying the factorization machine model. We conducted experiments on three aspect extraction datasets and five rating prediction datasets. To verify the effectiveness of the proposed aspect extraction model and rating prediction model, comparison experiments were made with some state-of-the-art baseline models, such as double embeddings convolutional neural network (DE-CNN) and dual graph convolutional …

This study explores information seeking behavior of second-generation Muslim immigrants utilizing factors such as critical, cultural, and religious literacy skills. The study examined the second-generation immigrants' ability to balance their parents' and grandparents' native culture and traditions with the culture and traditions of their country. The interview questions were designed using the cognitive authority theory and the figured worlds theory that provides an explanation for the mentality of those who are in environments influenced by culture or religion. An interesting main finding of the study is that participants sought more religious-based rather than culturally-based information. Participants seek information from their parents, communities, and religious leaders, but are particular with who they consider credible and reliable; if the person providing the information follows a similar lifestyle to the participants, they are more likely to hold cognitive authority. Four different themes emerged from the study. The first is "religious focus" where many participants stated that religion is rather static whereas culture can evolve and change with time, location, and events. The second theme emerged is the reliance on family members for religious literacy given the close upbringing of Muslim extended family system. The third theme indicated that although information seeking behavior relied …

Although digital equity is a recognized challenge in our K-12 school system, there is little research in using a holistic framework to investigate pre-conditions necessary for K-12 students to participate in digital learning and online processes. A conceptual framework of students' digital opportunity (SDO) is developed to represent the essential components of digital connectivity. The four key components are broadband internet availability, broadband usage, digital device ownership, and speed quality. A composite measure of SDO was created to quantitatively represent and measure the differences across 3,138 counties in the United States. Furthermore, spatial autocorrelation was applied to evaluate if the distribution of the SDO score is associated with geographical characteristics at the county level. The result showed the presence of significant county-level clusters with concentrations of high or low SDO scores. While the spatial analysis provided evidence of where the gaps in digital opportunities are located, there are underlying factors at the micro level that would need further investigation. This study suggests a collective approach between private and public entities to address the K-12 digital equity issue. The necessary conditions presented in the SDO model must be addressed first in order to bring change to K-12 students and schools in …

The purpose of this study was to assess visual analytics technology acceptance and user experience among in vitro fertilization (IVF) consumers. The research aimed to show how visual analytics tools and technologies can be applied in the consumer space to enhance how users interpret healthcare success rate data. This exploratory user evaluation study utilized a quantitative dominant, mixed-methods approach with a convergent parallel design based on the data-validation variant. Survey data were collected from consumers who were currently seeking information about IVF treatment in the United States. The study findings indicated that the extended unified theory of acceptance and use of technology (UTAUT2) constructs of performance expectancy and hedonic motivation influenced consumer behavioral intention to use visual analytics technology, while effort expectancy did not. Further, the findings from the user experience and qualitative analyses indicated that there is strong support for consumer adoption of visual analytics technology for personal healthcare decision-making. These findings may help in the design and development of modern, interactive visualization tools that could be used to visualize public or private healthcare data for analysis by consumers. Stakeholders, including the US Centers for Disease Control and Prevention, the World Health Organization, and medical practitioners, may use the …

Every citizen has the right to be equipped with scientific literacy to understand and make informed decisions within the discipline of science. Educators can utilize core science teaching practices (CSTPs) to develop scientific literacy. In response, this study identified the CSTPs utilized by preservice elementary teachers (PSETs) to develop scientific literacy during their spring 2022 student teaching semester. Furthermore, this study identified contextual constructs that led to the utilization of the CSTPs to develop scientific literacy. The study used a qualitative exploratory case study using semi-structured interviews as the primary data. Surveys and artifacts were used as supporting secondary data. The identification of CSTPs and their contextual constructs were conducted using inductive content analysis. Afterward, the identified CSTPs and their contextual constructs were deconstructed, interpreted, and synthesized through the critical theoretical framework of disciplinary literacy. Relationships, time, school structure, and community were contextual constructs that enabled and disabled PSETs' utilization of CSTPs to develop scientific literacy. The contextual constructs are represented using the Framework to Develop Scientific Literacy (FDSL). The FDSL contain contextual constructs that enabled PSETs to utilize CSTPs through the sharing of power between the PSET and their cooperating teacher, school district, community, or teacher education programs. In …

This study is the first attempt to review the role of AI approaches in COVID-19 vaccination-related sentiment analysis.

This study aimed to observe measurement invariance between community college students and university students in response to the Community of Inquiry (CoI) Survey instrument. Most studies of the CoI survey instruments have recorded and validated the instruments considering undergraduate or graduate students. This study sought to validate and prove the survey tool as a reliable instrument for the community college population. The study employed SEM and meta-analytic procedures to observe measurement invariance between a Monte Carlo generated general university sample population and the community college survey population. The findings are discussed, as well as the implications for CoI studies in the community college.

In this research the focus is on data-centric AI with a specific concentration on data quality evaluation and improvement for machine learning. We first present a practical framework for data quality evaluation and improvement, using a legal domain as a case study and build a corpus for legal argument mining. We first created an initial corpus with 4,937 instances that were manually labeled. We define five data quality evaluation dimensions: comprehensiveness, correctness, variety, class imbalance, and duplication, and conducted a quantitative evaluation on these dimensions for the legal dataset and two existing datasets in the medical domain for medical concept normalization. The first group of experiments showed that class imbalance and insufficient training data are the two major data quality issues that negatively impacted the quality of the system that was built on the legal corpus. The second group of experiments showed that the overlap between the test datasets and the training datasets, which we defined as "duplication," is the major data quality issue for the two medical corpora. We explore several widely used machine learning methods for data quality improvement. Compared to pseudo-labeling, co-training, and expectation-maximization (EM), generative adversarial network (GAN) is more effective for automated data augmentation, especially …

This dissertation provides empirical and theoretical support for the antecedents and consequences of cyber resilience via three essays on cyber resilience. Essay 1 comprises 2 studies using a multi-method empirical research effort to determine whether emphasizing suppliers' implementation and use of business continuity management (S-BCM) is actually beneficial to buyers. In Study 1, data from 150 managers was collected via a survey-based questionnaire to determine whether buyers' adoption of monitoring supplier operational performance (MS-OP) and monitoring S-BCM (MS-BCM) enhances S-BCM implementation and use. Evidence from Study 1 suggests that MS-BCM is more effective than MS-OP. Moreover, the results suggest that while buyer power positively augments the effectiveness of MS-BCM, it actually has a diminishing effect on the effectiveness of MS-OP. Study 2 uses the data of 114 managers from a vignette-based experiment to determine whether S-BCM leads to improved buyer operational and financial performance. Study 2 offers evidence that confirms the positive link between S-BCM and buyer operational and financial performance. The results also suggest that the use of reward power further enhances the association between S-BCM and buyer performance. Using two studies, Essay 2 examines how supply chain power and learning can be related to cyber resilience capability. Study …

Developing, implementing, and managing metadata is crucial to successful knowledge management, and academic libraries have traditionally played a central role in these activities. The Arabian Gulf countries are underrepresented in the existing research into library metadata practices. This exploratory study used semi-structured interviews of metadata managers at 8 universities with the goal of developing understanding of the current state of metadata practices, including descriptive cataloging, identity management, and knowledge organization in academic libraries of three Arabian Gulf countries (Kuwait, Oman, and Qatar), as well as potential future developments to facilitate discovery of resources. Findings provide insights into this previously under-researched area and contribute to understanding of knowledge management and risks on a global scale.
