Hashtag Recommendation Based On Neural Topic Model, Thunchanok Tangpong

Chulalongkorn University Theses and Dissertations (Chula ETD)

Hashtag recommendation is a method that aims to recommend the relevant hashtag to the target microblog. The previous work applies a topic model for discovering the topic of users, words, and hashtags. Despite their progress, two problems remain unresolved. Firstly, the previous work infers topic distribution by using a non-neural network framework which is a non-linear function, limiting the model's ability to capture topic distribution complexly. Secondly, the representation of words and hashtags used in the prior model is merely the frequency of words, making the model to ignore not only word context but also the relation between word and …

All Peer-Reviewed Publications

Although the black soldier fly frass fertiliser (BSFFF) is globally recognised as a promising and potential high-quality organic fertiliser, there is inadequate information on its impact on the growth performance and nutritional status of maize. Furthermore, no information exist on their combination with mineral fertiliser (NPK) as well as economic impact on maize production. This study evaluated the comparative impact of BSFFF, NPK and commercial organic fertiliser (Evergrow®) on growth, nitrogen use efficiency, yield, nutritional quality, and profitability of maize under greenhouse conditions. The treatments included: (1) sole application of BSFFF, conventional compost of brewers’ spent grain (BSG), Evergrow, and …

Generation 1.5 Students’ Academic Success: The Interrelationship Between Capital Used And Identity Formation, Susan D. Dudley

Theses and Dissertations

As the number of people immigrating to the United States increases, so does the number of generation 1.5 students in K-12 education (Kanno & Cromley, 2013). With more generation 1.5 students graduating from U.S. high schools, more are also matriculating into higher education institutions (Harklau & Siegal, 2009; Kanno & Cromley, 2013; Kanno & Harklau, 2012; Roberge, 2009). While some generation 1.5 students are successful in U.S. higher education, others are not, and the percentage of generation 1.5 students who are successful is disproportionately less than the percentage of those students who have a U.S. heritage culture (Kanno & Harklau, …

Temporal Disambiguation Of Relative Temporal Expressions In Clinical Texts Using Temporally Fine-Tuned Contextual Word Embeddings., Amy L. Olex

Theses and Dissertations

Temporal reasoning is the ability to extract and assimilate temporal information to reconstruct a series of events such that they can be reasoned over to answer questions involving time. Temporal reasoning in the clinical domain is challenging due to specialized medical terms and nomenclature, shorthand notation, fragmented text, a variety of writing styles used by different medical units, redundancy of information that has to be reconciled, and an increased number of temporal references as compared to general domain texts. Work in the area of clinical temporal reasoning has progressed, but the current state-of-the-art still has a ways to go before …

The Civil Right To Belong: A Case Study On Immigrant Integration Of Muslim Students In Educational Institutions, Mamoona H. Siddiqui

Theses and Dissertations

Constitutional equal protection values serve as social integration policies for new Americans and generations that follow. They promise equal opportunity, fair treatment, protection from unlawful discrimination, and freedom to preserve cultural identities in their new communities. However, in times of national security crises and political polarization, the disjuncture in the way equal protection doctrines have been historically implemented often reflect deep-rooted inequities that impact underrepresented communities. American Muslims are one such community in which members have experienced anti-Muslim and anti-immigrant sentiment particularly after 9/11 and political polarization on immigration and civil rights policies. The study explores the equal protection doctrine …

Theses and Dissertations

Childhood Reliquary De Una CatrachaMexi Entre Nopales is a multisensory based installation consisting of three large and six medium scale mixed media paintings with performance. It is informed by my upbringing in Boyle Heights in the projects during the 90s, followed by East LA in the mid 2000s. It is the reliquary for my discomfort in institutional spaces and why I have found comfort in dystopian-like installations. This is the landscape in which I exist, regardless of where I am now. It is where I place my work. It is the context in which I celebrate the powerful delicacy of …

Incorporating Ontological Information In Biomedical Entity Linking Of Phrases In Clinical Text, Evan French

Theses and Dissertations

Biomedical Entity Linking (BEL) is the task of mapping spans of text within biomedical documents to normalized, unique identifiers within an ontology. Translational application of BEL on clinical notes has enormous potential for augmenting discretely captured data in electronic health records, but the existing paradigm for evaluating BEL systems developed in academia is not well aligned with real-world use cases. In this work, we demonstrate a proof of concept for incorporating ontological similarity into the training and evaluation of BEL systems to begin to rectify this misalignment. This thesis has two primary components: 1) a comprehensive literature review and 2) …

Using Individual Determinants To Predict Behavioral Health Service Use In Integrated Pediatric Primary Care, Alfonso L. Floyd Jr.

Theses and Dissertations

Mental health problems (e.g., attention, externalizing, internalizing) are commonly observed in youth and are often associated with significant impairment and an increased need for mental health services. Conceptual frameworks, such as Andersen’s Behavioral Model of Health Service Utilization, have proposed that several individual determinants (e.g., predisposing, enabling, and need factors) may influence service use for mental health problems among youth. Despite the glaring need for mental health treatment among youth with mental health problems, studies indicate that many affected youths do not receive mental health care. Integrated pediatric primary care (IPPC) settings provide an ideal setting for youth and families …

Predicting Medication Adherence Patterns During The Maintenance Phase Of Treatment For Pediatric Leukemia And Lymphoma: A Model Of Individual- And Family-Level Factors, Stephanie M. Romo

Theses and Dissertations

Adherence during the maintenance phase of pediatric cancer treatment is critical to prevent relapse and ensure long-term, event-free survival. Yet, little research has been done to examine individual- and family-level factors that may relate to adherence during the maintenance phase of treatment, particularly among Latinx patients. This is surprising given findings demonstrating that children who miss more than 5% of their prescribed oral chemotherapy medicine, most commonly 6-mercaptopurine (6MP), are 2.5-2.7 times more likely to relapse than children who take 95% or more of their prescribed 6MP. Pediatric cancer patients face unique adherence challenges given the importance of family involvement …

Arts Integration Experiences Of Elementary Educators, Amy E. Jefferson

Theses and Dissertations

The purpose of this study was to examine how elementary teachers applied their professional learning to integrate arts in the classroom. The research questions guiding the study included: (1) What content, skills, and understandings do teachers transfer from professional learning to practice? and (2) How do teachers navigate the implementation of arts integration? Knowles' (1978) Adult Learning Theory was used to examine how meeting the needs of teachers as adult learners during professional learning influenced the implementation experience.

A case study design employing qualitative data collection methods such as focus groups, individual interviews, and the sharing of artifacts from practice …

Putting The "Video" Back In Video Games: Opportunities And Challenges For Visual Studies Approaches To Video Game Analysis, Francis A. Longaker

Theses and Dissertations

I argue for the application of visual studies in video game analysis. This approach presents opportunities for the intersectional analysis of video game visuals as games are brought into dialogue with other visual media like film and painting. This approach also presents challenges due to ontological distinctions between different media as well as due to academic divisions regarding the study of different art and media objects. Despite the challenges presented, a visual studies approach is particularly useful as a critical window into contemporary visual culture at large.

I outline the fields of game studies and visual studies, marking their distinctions …

Occasional Papers on Religion in Eastern Europe

The article analyzes the development of Ukrainian Orthodoxy in the context of the revenge policy of Russia against Ukraine at the turn of the 21st century. It is discovered that almost a quarter of a century of inactivity of the Ukrainian authorities and active anti-Ukrainian and anti-state actions of the Russian Orthodox Church and its Little-Russian branch the Ukrainian Orthodox Church of the Moscow Patriarchate contributed to their introduction into the Ukrainian humanitarian space of fundamental ideas, dogmas, and postulates of the “Russian World,” which subsequently led to the occupation by Russia of Crimea and parts of Donbas and the …
