The Greek Merchant Marine: A Unique Combination Of Nautical Skill And Commercial Savvy, Alexander Billinis

All Theses

The Greek-owned merchant fleet remains the world’s largest, and while plenty of histories have been written about this fleet, there is a definite absence in the historiography about why the Greeks’ relation to the sea is unique, and how this fleet came into existence. The author argues that the Greek merchant fleet is a successful hybridization of a commercial middleman minority ethos born out of conditions in the Ottoman Empire and post-independence Greece, combined with the shipping skills of a littoral people who invested in this expertise.

To understand the how and why of the Greek merchant fleet, it is …

Assessment Design For Digital Education: An Analytics-Based Authentic Assessment Approach, Lim Ming Soon Tristan, Gottipati Swapna, Michelle L. F. Cheong, Christopher Pang, Jun Wei Ng

Research Collection School Of Computing and Information Systems

This study looks to identify an assessment design construct that overcomes known issues in authentic assessment design practices in digital education. These include lack of "freedom-of-choice", lack of focus on multimodal nature of the digital process, and shortage of effective feedbacks. This study proposes an authentic assessment, that combines gamification (G) with heutagogy (H) and multimodality (M) of assessments, building upon learning analytics (A), known as GHMA. Proposed assessment design is a skills-oriented game-based assessment approach. Learners can determine their own goals and create individualized multimodal artefacts; receive cognitive challenge through cognitively complex tasks structured in gamified non-linear learning paths; …

Learning Dynamic Multimodal Implicit And Explicit Networks For Multiple Financial Tasks, Meng Kiat Gary Ang, Ee-Peng Lim

Research Collection School Of Computing and Information Systems

Many financial f orecasting d eep l earning w orks focus on the single task of predicting stock returns for trading with unimodal numerical inputs. Investment and risk management however involves multiple financial t asks - f orecasts o f expected returns, risks and correlations of multiple stocks in portfolios, as well as important events affecting different stocks - to support decision making. Moreover, stock returns are influenced by large volumes of non-stationary time-series information from a variety of modalities and the propagation of such information across inter-company relationship networks. Such networks could be explicit - observed co-occurrences in online …

R2f: A General Retrieval, Reading And Fusion Framework For Document-Level Natural Language Inference, Hao Wang, Yixin Cao, Yangguang Li, Zhen Huang, Kun Wang, Jing Shao

Research Collection School Of Computing and Information Systems

Document-level natural language inference (DocNLI) is a new challenging task in natural language processing, aiming at judging the entailment relationship between a pair of hypothesis and premise documents. Current datasets and baselines largely follow sentence-level settings, but fail to address the issues raised by longer documents. In this paper, we establish a general solution, named Retrieval, Reading and Fusion (R2F) framework, and a new setting, by analyzing the main challenges of DocNLI: interpretability, long-range dependency, and cross-sentence inference. The basic idea of the framework is to simplify document-level task into a set of sentence-level tasks, and improve both performance and …

Towards Reinterpreting Neural Topic Models Via Composite Activations, Jia Peng Lim, Hady Wirawan Lauw

Research Collection School Of Computing and Information Systems

Most Neural Topic Models (NTM) use a variational auto-encoder framework producing K topics limited to the size of the encoder’s output. These topics are interpreted through the selection of the top activated words via the weights or reconstructed vector of the decoder that are directly connected to each neuron. In this paper, we present a model-free two-stage process to reinterpret NTM and derive further insights on the state of the trained model. Firstly, building on the original information from a trained NTM, we generate a pool of potential candidate “composite topics” by exploiting possible co-occurrences within the original set of …

Biasfinder: Metamorphic Test Generation To Uncover Bias For Sentiment Analysis Systems, Muhammad Hilmi Asyrofi, Zhou Yang, Imam Nur Bani Yusuf, Hong Jin Kang, Thung Ferdian, David Lo

Research Collection School Of Computing and Information Systems

Artificial intelligence systems, such as Sentiment Analysis (SA) systems, typically learn from large amounts of data that may reflect human bias. Consequently, such systems may exhibit unintended demographic bias against specific characteristics (e.g., gender, occupation, country-of-origin, etc.). Such bias manifests in an SA system when it predicts different sentiments for similar texts that differ only in the characteristic of individuals described. To automatically uncover bias in SA systems, this paper presents BiasFinder, an approach that can discover biased predictions in SA systems via metamorphic testing. A key feature of BiasFinder is the automatic curation of suitable templates from any given …

A Unified Dialogue User Simulator For Few-Shot Data Augmentation, Dazhen Wan, Zheng Zhang, Qi Zhu, Lizi Liao, Minlie Huang

Research Collection School Of Computing and Information Systems

Pre-trained language models have shown superior performance in task-oriented dialogues. However, existing datasets are on limited scales, which cannot support large-scale pre-training. Fortunately, various data augmentation methods have been developed to augment largescale task-oriented dialogue corpora. However, they heavily rely on annotated data in the target domain, which require a tremendous amount of data collection and human labeling work. In this paper, we build a unified dialogue user simulation model by pre-training on several publicly available datasets. The model can then be tuned on a target domain with fewshot data. The experiments on a target dataset across multiple domains show …

The Language Of Recruitment: How Minority Status, Racial Minority Centrality, & Linguistic Cues Impact Applicant Perceptions, Clark Waters

Theses and Dissertations

As color-blindness, the intentional denial of racial differences, continues to occupy corporate policy, expressions and consequences of modern racism in the workplace remain pervasive. Color-blind attitudes can be harmful due to their focus on perceived equality, at the expense of actionable, functional equity. Establishing a culture of racial equity in the workplace requires an understanding of how the language used to discuss race can impact potential applicants’ opinions of the company. To attract a diverse pool of job applicants, the language of recruitment is of particular importance in the current study. Using a vignette-style survey design, a diverse sample of …

Conreader: Exploring Implicit Relations In Contracts For Contract Clause Extraction, Weiwen Xu, Yang Deng, Wenqiang Lei, Wenlong Zhao, Tat-Seng Chua, Wai Lam

Research Collection School Of Computing and Information Systems

We study automatic Contract Clause Extraction (CCE) by modeling implicit relations in legal contracts. Existing CCE methods mostly treat contracts as plain text, creating a substantial barrier to understanding contracts of high complexity. In this work, we first comprehensively analyze the complexity issues of contracts and distill out three implicit relations commonly found in contracts, namely, 1) Long-range Context Relation that captures the correlations of distant clauses; 2) Term-Definition Relation that captures the relation between important terms with their corresponding definitions; and 3) Similar Clause Relation that captures the similarities between clauses of the same type. Then we propose a …

Pacific: Towards Proactive Conversational Question Answering Over Tabular And Textual Data In Finance, Yang Deng, Wenqiang Lei, Wenxuan Zhang, Wai Lam, Tat-Seng Chua

Research Collection School Of Computing and Information Systems

To facilitate conversational question answering (CQA) over hybrid contexts in finance, we present a new dataset, named PACIFIC. Compared with existing CQA datasets, PACIFIC exhibits three key features: (i) proactivity, (ii) numerical reasoning, and (iii) hybrid context of tables and text. A new task is defined accordingly to study Proactive Conversational Question Answering (PCQA), which combines clarification question generation and CQA. In addition, we propose a novel method, namely UniPCQA, to adapt a hybrid format of input and output content in PCQA into the Seq2Seq problem, including the reformulation of the numerical reasoning process as code generation. UniPCQA performs multi-task …

Which ethical guidelines would we use to implement such a system? How would we …

The Importance And Implementation Of Kinesthetic Learning In The English Classroom, Emma Crandall

Senior Honors Theses

This paper examines different educators’ and researchers’ activities for kinesthetic learners and discusses how they can be applied to the English classroom in literature, writing, and language. The first section delves into the difficulty associated with but ultimate importance of including kinesthetic learning activities for both kinesthetic and non-kinesthetic learners due to the benefits of active learning. Subsequently, it looks for synthesis between different types of kinesthetic activities, dividing them into the categories of manipulatives, commonly accepted classroom activities with kinesthetic add-ons, and kinesthetic-centered activities. The ways each activity can be used, including its benefits and disadvantages, are discussed, and …

Sex-Related Differences In Violence Exposure, Neural Reactivity To Threat, And Mental Health, Heather E Dark, Nathaniel G Harnett, Danielle R Hurst, Muriah D Wheelock, Kimberly H Wood, Adam M Goodman, Sylvie Mrug, Marc N Elliott, Susan Tortolero Emery, Mark A Schuster, David C Knight

Faculty, Staff and Student Publications

The prefrontal cortex (PFC), hippocampus, and amygdala play an important role in emotional health. However, adverse life events (e.g., violence exposure) affect the function of these brain regions, which may lead to disorders such as depression and anxiety. Depression and anxiety disproportionately affect women compared to men, and this disparity may reflect sex differences in the neural processes that underlie emotion expression and regulation. The present study investigated sex differences in the relationship between violence exposure and the neural processes that underlie emotion regulation. In the present study, 200 participants completed a Pavlovian fear conditioning procedure in which cued and …

Analysis Of The Issue Of New Mexico Black Male Educators’ Underrepresentation In Education Within New Mexico, Robert Sims Jr.

Dissertations

Increasing the educational profession's racial, gender, and ethnic diversification ensures the intentionality and equity of having more Black male educators serve as role models in U.S. schools. There is a need to understand better the journey and experiences of Black male educators, wherefore greater grassroots recruitment and retention efforts can be implemented to support Black men and young Black males who may aspire to become educators. Research that captures the experiences of Black male youth and educators as they navigate teaching and learning in predominately White educational systems may promote lines of inquiry for further research and intentional dialogue for …

Increasing Classroom Teachers' Use Of Linguistically Responsive Strategies To Support English Language Learners: A Mixed-Methods Study, Christie Shealy

All Dissertations

With the dawn of the new decade, English Language Learner (ELL) populations began to grow in states without structures and professional learning to equip teachers to face the changing demographic of the classroom. In response to the growth of the knowledge gap between classroom teachers in South Carolina and their diverse classrooms, I conducted a study based on improvement science principles. As a long-standing ELL program coordinator, I experienced the need to increase linguistic responsiveness in classroom teachers on a daily basis. The application of the plan-do-study-act (PDSA) cycle utilized mixed methodology to gather data to increase classroom teachers’ use …

Identity Tensions And Negotiations Of English Teachers In Costa Rica Through Narrative Inquiry, Hazel Vega Quesada

All Dissertations

This study examined the identity tensions and negotiations of novice three English teachers in Costa Rica, and English as a foreign language context. Grounded in a Communities of Practice framework, this research describes how teachers’ identities are constrained and enabled in complicated academic, social, and political settings. In this study, identity tensions referred to dilemmas that juxtaposed internal and external expectations, values, and practices. Negotiations referred to teachers’ choices, proposals, and changes that denoted their appropriation or contestation of practices and meanings of their communities of practice. I used narrative inquiry to collect and analyze teachers’ experiences learning English and …

An End-To-End Pipeline From Law Text To Logical Formulas, Aarne Ranta, Inari Listenmaa, Jerrold Soh, Meng Weng Wong

Research Collection Yong Pung How School Of Law

We propose a pipeline for converting natural English law texts into logical formulas via a series of structural representations. Text texts are first parsed using a formal grammar derived from light-weight annotations. An intermediate representation called assembly logic is then used for logical interpretation and supports translations to different back-end logics and visualisations. The approach, while rule-based and explainable, is also robust: it can deliver useful results from day one, but allows subsequent refinements and variations.

Examining The Politicization And Framing Of Hea 117 In The Us Between 2019 And 2021, Elise S. Ahn

Journal of Comparative & International Higher Education

In 2019, the U.S. Department of Education (DED) began increasing its enforcement of the Higher Education Act, Section 117 statute, which provides instructions for institutional reporting regarding foreign and contracts. The three questions guiding this article include: What were DED’s stated premises for the investigations? How was international engagement characterized in the notices? And finally, what traits, characteristics, and/or qualities were attributed to different actors? After providing an overview of Section 117, this article examines the notices of investigation issued by DED between 2019 and 2021 to better understand how the Agency discursively characterized malign and/or undue foreign influence utilizing …

“An Exercise In International Extortion”: Operation “Intercept” And Nixon’S 1969 War On Drugs, Justin M. Reid

War, Diplomacy, and Society (MA) Theses

When the former senator and vice president assumed the Oval Office in January 1969, President Richard M. Nixon inherited a nation in crisis with drugs playing a central role. At a campaign stop a few months earlier, Nixon announced to a packed convention center in Anaheim, CA, that if elected president he would end the flow of the illicit drugs coming into the United States “decimating a generation of young Americans.”

True to his word, Nixon moved aggressively after his election victory to refocus the federal drug enforcement bureaucracy on drug source control, blaming Mexico as the main culprit. On …

“The Taste Of This Country”: Jefferson’S Legacy Of Cultural Production And The Formation Of American Identity, Erika Gibson

War, Diplomacy, and Society (MA) Theses

This paper uses three fundamental elements of cultural anthropology, food, customs, and language, to examine Jefferson’s diplomatic strategy as president and understanding how he forged a new culture rooted in republicanism. The legacy of tyrannical British rule spurred Jefferson to establish White House protocol which dispensed with the hierarchies of European social practices and instead mirrored republican values of liberty and equality. Analyzing Jefferson’s presidency within a framework of cultural production, reveals that Jefferson strategically deployed cultural elements in the construction of a distinctly American identity.

The "Therapeutic Relationship:" Emergence, Eclipse, And Transformations Of A Social Technology., Ulrich Koch

Clinical Research and Leadership Faculty Publications

This essay situates the history of "the relationship" as a therapeutic technology within the broader context of changing social relations in the twentieth-century United States. More specifically, it outlines the emergence and subsequent diffusion of practices that aim to cultivate a social bond between therapist and patient that may serve as a psychotherapeutic tool. The article highlights the transformations of this technology as its institutional and epistemic foundations became challenged. Initially conceived as an "artificial" social relation designed to help with "personal adjustment," the therapeutic relationship was soon also deployed by non-experts and became a model for more healthful social …

Predicting Startup Success Using Publicly Available Data, Emily Gavrilenko

Master's Theses

Predicting the success of an early-stage startup has always been a major effort for investors and venture funds. Statistically, there are about 305 million total startups created in a year, but less than 10% of them succeed to become profitable businesses. Accurately identifying the signs of startup growth is the work of countless investors, and in recent years, research has turned to machine learning in hopes of improving the accuracy and speed of startup success prediction.

To learn about a startup, investors have to navigate many different internet sources and often rely on personal intuition to determine the startup’s potential …

Happy Objects And Bloom Spaces: Investigating The Potential Of Rupi Kaur's Poetry, Miguel Vega

Electronic Theses, Projects, and Dissertations

In response to the movement of what is considered and labeled as “Instagram poetry,” poet and critic Rebecca Watts argues that to consider “artless” poetry as “poetry” we are denigrating the artform. This project centers around Watts’ claim that “the reader is dead” due to their encounter with such poetry. This project acts as a conversation that seeks to understand why certain forms of art are considered a “threat” to those who engage with them, as well as to their respective fields. Using affect theory (specifically the theory of the happy object) we can begin to understand why we gravitate …

Development Of The Teaching Twice Exceptional Students Scale, Michelle Ann Godzinski

Dissertations

Twice exceptional (2e) students are a unique population of students, who present with a wide range of strengths and weaknesses. For this reason, it is important for teachers to be trained and feel prepared to work with these students. Teacher self-efficacy has been shown to influence both student and personal outcomes (e.g. student perceptions of school, student academic success, teacher retention, etc). The Teaching Twice Exceptional Students Scale (TTESS) was developed as a way to measure teacher’s self-efficacy in regard to working with 2e students, so that districts may better identify gaps in knowledge or training that teachers may have. …
