What are the possibilities of 360 audio to expand compositional practice?

This graduate project employed a mixed methodology to research the field of 360 audio and its potential to expand DAW-based compositional practice. The outcomes of the project include a body of new 360 audio compositions, a range of demonstrative 360 audio samples, and an accompanying exegesis.

Specifically, my research looks at 360 composition using ambisonic plugins, and the binaurally decoded output for headphone delivery. A literature review of human spatial hearing and contemporary 360 audio practice has been conducted, and research-led practice has been used to explore concepts and …

Self-Supervised Learning Disentangled Group Representation As Feature, Tan Wang, Zhongqi Yue, Jianqiang Huang, Qianru Sun, Hanwang Zhang

Research Collection School Of Computing and Information Systems

A good visual representation is an inference map from observations (images) to features (vectors) that faithfully reflects the hidden modularized generative factors (semantics). In this paper, we formulate the notion of “good” representation from a group-theoretic view using Higgins’ definition of disentangled representation [38], and show that existing Self-Supervised Learning (SSL) only disentangles simple augmentation features such as rotation and colorization, thus unable to modularize the remaining semantics. To break the limitation, we propose an iterative SSL algorithm: Iterative Partition-based Invariant Risk Minimization (IP-IRM), which successfully grounds the abstract semantics and the group acting on them into concrete contrastive learning. …

Automated Doubt Identification From Informal Reflections Through Hybrid Sentic Patterns And Machine Learning Approach, Siaw Ling Lo, Kar Way Tan, Eng Lieh Ouh

Research Collection School Of Computing and Information Systems

Do my students understand? The question that lingers in every instructor’s mind after each lesson. With the focus on learner-centered pedagogy, is it feasible to provide timely and relevant guidance to individual learners according to their levels of understanding? One of the options available is to collect reflections from learners after each lesson to extract relevant feedback so that doubts or questions can be addressed in a timely manner. In this paper, we derived a hybrid approach that leverages a novel Doubt Sentic Pattern Detection (SPD) algorithm and a machine learning model to automate the identification of doubts from students’ …

Research Collection School Of Computing and Information Systems

To contribute to a better understanding of the contemporary realities of AI workplace deployments, the authors recently completed 29 case studies of people doing their everyday work with AI-enabled smart machines. Twenty-three of these examples were from North America, mostly in the US. Six were from Southeast Asia, mostly in Singapore. In this essay, we compare our findings on job and workplace impacts to those reported in the MIT Task Force on the Work of the Future report, as we consider that to be the most comprehensive recent study on this topic.

Imon: Appearance-Based Gaze Tracking System On Mobile Devices, Sinh Huynh, Rajesh Krishna Balan, Jeonggil Ko

Research Collection School Of Computing and Information Systems

Gaze tracking is a key building block used in many mobile applications including entertainment, personal productivity, accessibility, medical diagnosis, and visual attention monitoring. In this paper, we present iMon, an appearance-based gaze tracking system that is both designed for use on mobile phones and has significantly greater accuracy compared to prior state-of-the-art solutions. iMon achieves this by comprehensively considering the gaze estimation pipeline and then overcoming three different sources of errors. First, instead of assuming that the user's gaze is fixed to a single 2D coordinate, we construct each gaze label using a probabilistic 2D heatmap gaze representation input to …

On Analysing Student Resilience In Higher Education Programs Using A Data-Driven Approach, Audrey Tedja Widjaja, Ee-Peng Lim, Aldy Gunawan

Research Collection School Of Computing and Information Systems

Analysing student resilience is important as research has shown that resilience is related to students’ academic performance and their persistence through academic setbacks. While questionnaires can be conducted to assess student resilience directly, they suffer from human recall errors and deliberate suppression of true responses. In this paper, we propose ACREA, ACademic REsilience Analytics framework which adopts a data-driven approach to analyse student resilient behavior with the use of student-course data. ACREA defines academic setbacks experienced by students and measures how well students overcome such setbacks using a quasi-experimental design. By applying ACREA on a real world student-course dataset, we …

Rmm: Reinforced Memory Management For Class-Incremental Learning, Yaoyao Liu, Qianru Sun, Qianru Sun

Research Collection School Of Computing and Information Systems

Class-Incremental Learning (CIL) [38] trains classifiers under a strict memory budget: in each incremental phase, learning is done for new data, most of which is abandoned to free space for the next phase. The preserved data are exemplars used for replaying. However, existing methods use a static and ad hoc strategy for memory allocation, which is often sub-optimal. In this work, we propose a dynamic memory management strategy that is optimized for the incremental phases and different object classes. We call our method reinforced memory management (RMM), leveraging reinforcement learning. RMM training is not naturally compatible with CIL as the …

Etherlearn: Decentralizing Learning Via Blockchain, Nguyen Binh Duong Ta, Tian Jun Joel Yang

Research Collection School Of Computing and Information Systems

In institutes of higher learning, most of the time course material development and delivery follow a centralized model which is fully lecturer-controlled. In this model, engaging students as partners in learning is a challenging problem as: 1) students are usually hesitant to contribute due to the fear of getting it wrong, 2) not much incentive for them to put in the extra effort, and 3) current online learning systems lack adequate facilities to support seamless and anonymous interactions between students. In this work, we propose EtherLearn, a blockchain based peer-learning system to distribute the control of how course material and …

Bundled Earnings Guidance And Analysts' Forecast Revisions, Charles Hsu, Rencheng Wang

Research Collection School Of Accountancy

Bundling managerial earnings guidance with quarterly earnings announcements (EAs) has become an increasingly common practice. This study investigates the impact of bundled guidance on analysts' forecast revisions. Our findings indicate that analysts respond more to bundled guidance than non-bundled guidance. This effect increases with analysts' time pressure and cognitive constraints around the EA. Analysts' revisions also incorporate more of the bundled management guidance when accompanied by additional information, such as conference calls. We further find that analysts revise their forecasts more quickly following bundled guidance than non-bundled guidance. Together, these findings are consistent with the notion that analysts place more …

The Impact Of The Ifrs 9 Expected Loss Approach On Accounting Conservatism, Clarence Goh, Chu Yeong Lim, Kevin Ow Yong

Research Collection School Of Accountancy

Using an experimental setting, this paper examines the impact of the International Financial Reporting Standard (IFRS 9) expected credit loss (ECL) approach on accounting conservatism. The ECL approach enables banks to incorporate loan loss provisions (LLP) on a timelier basis and help bank regulators anticipate weaknesses in banks’ loan portfolios. Conversely, the ECL model could be more susceptible to managerial discretion. More conservative bank managers might make excessivecredit provisions. Our findings show that high conservatism is positively associated with higher levels of LLP. In addition, the effect of accounting conservatism is contingent upon the type of loan loss model. We …

Beyond Shareholder Value? Why Firms Voluntarily Disclose Support For Black Lives Matter, A. J. Chen, Patricia M. Dechow, Samuel T. Tan

Research Collection School Of Accountancy

We investigate why firms voluntarily disclose support for the Black Lives Matter movement (BLM firms) even though these disclosures have little impact on shareholder value. We examine two competing explanations: that managers are acting in the interests of a broad set of stakeholders, or that they are engaging in “woke-washing.” Our evidence supports the stakeholder perspective since we find that BLM firms have more inclusive cultures on multiple dimensions – from their board members, to employees, to the rights of shareholders, and to the compensation structure of top executives. Furthermore, BLM firms face less risk in speaking out since they …

Checking Smart Contracts With Structural Code Embedding, Zhipeng Gao, Lingxiao Jiang, Xin Xia, David Lo, John Grundy

Research Collection School Of Computing and Information Systems

Smart contracts have been increasingly used together with blockchains to automate financial and business transactions. However, many bugs and vulnerabilities have been identified in many contracts which raises serious concerns about smart contract security, not to mention that the blockchain systems on which the smart contracts are built can be buggy. Thus, there is a significant need to better maintain smart contract code and ensure its high reliability. In this paper, we propose an automated approach to learn characteristics of smart contracts in Solidity, useful for repetitive contract code, bug detection and contract validation. Our new approach is based on …

A Fine-Grained Attribute Based Data Retrieval With Proxy Re-Encryption Scheme For Data Outsourcing Systems, Hanshu Hong, Ximeng Liu, Zhixin Sun

Research Collection School Of Computing and Information Systems

Attribute based encryption is suitable for data protection in data outsourcing systems such as cloud computing. However, the leveraging of encryption technique may retrain some routine operations over the encrypted data, particularly in the field of data retrieval. This paper presents an attribute based date retrieval with proxy re-encryption (ABDR-PRE) to provide both fine-grained access control and retrieval over the ciphertexts. The proposed scheme achieves fine-grained data access management by adopting KP-ABE mechanism, a delegator can generate the re-encryption key and search indexes for the ciphertexts to be shared over the target delegatee’s attributes. Throughout the process of data sharing, …

Research outputs 2014 to 2021

This study explores how the first wave of the COVID‐19 pandemic influenced family routines, relationships and technology use (smartphones and tablet computers) among families with infants. Infancy is known to be an important period for attachment security and future child development, and a time of being susceptible to changes within and outside of the family unit. A qualitative design using convenience sampling was employed. A total of 30 mothers in Perth, Western Australia participated in semi‐structured interviews by audio or video call. All mothers were parents of infants aged 9 to 15 months old. Interviews were audio‐recorded and transcribed, and …

Bostock Was Bogus: Textualism, Pluralism, And Title Vii, Mitchell N. Berman, Guha Krishnamurthi

Notre Dame Law Review

In Bostock v. Clayton County, one of the blockbuster cases from its 2019 Term, the Supreme Court held that federal antidiscrimination law prohibits employment discrimination on grounds of sexual orientation and gender identity. Unsurprisingly, the result won wide acclaim in the mainstream legal and popular media. Results aside, however, the reaction to Justice Neil Gorsuch’s majority opinion, which purported to ground the outcome in a textualist approach to statutory interpretation, was more mixed. The great majority of commentators, both liberal and conservative, praised Justice Gorsuch for what they deemed a careful and sophisticated—even “magnificent” and “exemplary”—application of textualist principles, …

Forum Selection Clauses, Non-Signatories, And Personal Jurisdiction, John F. Coyle, Robin J. Effron

Notre Dame Law Review

Who is bound by a forum selection clause? At first glance, the answer to this question may seem obvious. It is black letter law that a person cannot be bound to an agreement without her consent. In recent years, however, courts have not followed this rule with respect to forum selection clauses. Instead, they routinely enforce these clauses against individuals who never signed the contract containing the clause. Courts justify this practice on the grounds that it promotes litigation efficiency by bringing all of the litigants together in the chosen forum. There are, however, problems with enforcing forum selection clauses …

It’S A Trap: A New Economic Model Addressing American Public Education, Nikhil A. Gulati

Notre Dame Law Review

This Note will argue that, when looking at the quality of a school district, there is some theoretical threshold that determines whether the use of local property tax and zoning by a local government will be effective in increasing the quality of the locality’s schools. This theoretical threshold is conceptually akin to the basic economic idea of a poverty trap. If a locality’s schools are above this quality threshold, the corresponding local government will be able to effectively utilize property taxes and zoning to increase the quality of its schools. However, if it is below the threshold, the local government …

Exploring The Relationship Between Trauma, Motivation, Current Stress, And Immigrant Elementary Students, Jayme Branagh Landon

Doctoral Dissertations and Projects

The current study explored the relationship between past trauma of immigrant students and motivation in a group of public-school elementary students in Washington state. Additionally, this study explored how stress affects academic motivation. It was hypothesized that past trauma would significantly affect immigrant student motivation and that current stress would moderate motivation in school. Only students with past trauma experience and who qualify as an immigrant, were included in this study. Participants completed The Cameron Complex Trauma Interview (CCTI), Motivated Strategies for Learning Questionnaire (MSLQ), and The Perceived Stress Scale for Children (PSS-C). While motivation has been studied, the factors …

Developing An Intentional Disciple Making Strategy For Fathers To Lead Their Families In Spiritual Transformation, Michael Cauthorne

Doctoral Dissertations and Projects

Do current student ministries produce disciples that can stand the test of the current culture? Has creating a separate ministry worked against God’s plan for making disciples? Statistics from across the Church would suggest the American Church is in decline. Within the Southern Baptist Convention there has been a continual decline in baptisms over the past few years. This project will seek to determine if there is a correlation between how student ministries are led in the modern church to how effectively the church has been in making disciples. With research and data collected from current and former student ministries, …

Chaplaincy: A Practical Approach To Caring For The Human Spirit, Susan Fair

Doctoral Dissertations and Projects

This DMIN project is based on the Pastoral Ministry program at Nyack College, which publicly promotes that it leads the student to become a professional in the ministry context. The problem is that the academic curriculum does not include components of Clinical Pastoral Education (CPE). The project facilitator reasons that the current environment demands that spiritual care providers possess a specific skill set extending beyond pulpit preaching, reading scriptures, and prayer. The literature review contains articles, journals, and books that explore caring for the human spirit within the physical, spiritual, emotional, financial, religious, and holistic context. The research methodology designed …

From Perpetual Struggle To Liberation And Freedom: An Analysis Of Two Predominately African American Churches, Stanley Bernard Baldwin Ii

Doctoral Dissertations and Projects

African American Church Music has a unique and robust history dating back to the era of the African Slave Trade. This project will focus on African American Church Music and its effect on the African American worship experience in the 21st century. The creation of spirituals and gospel music helped shape the doctrine and identity in the African American Church. However, its message of suffering and “longing to go home” has limited the worship experience of the African American demographic. Musical style, historical significance, and racial issues have played a significant role in shaping the African American worship experience. These …

New Urban Liturgy: Making A Lane For Hip-Hop In Multicultural Worship, Caleb Thomas Kudlo

Doctoral Dissertations and Projects

The urban environments of American cities are home to diverse cultures and subcultures. If God created humanity in His image, and if the gospel of Jesus Christ has transcending power, then urban churches are poised to become worship communities that reflect His creativity and redemption. However, the ideal of unity in diversity strives against the currents of homogenization in American history, church traditions, and human nature. This project brings attention to a subculture that makes its home in the urban environments of American cities but not in its churches: hip-hop should be counted among the diverse cultures that can uniquely …

Understanding Eschatology Leads To A More Fruitful Christian Life, John Michael Mendola

Doctoral Dissertations and Projects

The evangelical church cannot fulfill its mission to facilitate the return of Jesus unless its membership’s studies eschatology. Too many relegate biblical prophecies to the past without recognizing their fulfillment in the here and now. This study investigates the contemporary belief structure of church members and aims to develop an effective corrective measure in order to improve the spiritual life of its members while advancing the church’s central mission of evangelizing. This study aims to determine what members know about church viewpoints on eschatology and deliver an educational remedy. The 15-person sample received a six-week course on eschatology developed and …

A Contemporary, Modified Suzuki Curriculum For The Beginning Trumpet Player, Brendan Holly

Doctoral Dissertations and Projects

Through music education symposiums such as the Tanglewood Symposium and Vision: 2020, calls for popular music's inclusion into the public school music curriculum have been made and heard worldwide. In response, public schools have produced new curricula for popular music courses such as rock band, music technology, and other contemporary music classes. In contrast, traditional music courses such as band, choir, and orchestra have remained unchanged. Despite various beginner trumpet method books and content delivery methods, limited curriculum and methods for content delivery exist to prepare beginning trumpet players for interaction with popular music. This qualitative research study critically examined …

Analysis Of Texas Collegiate Mariachi Ensembles: Standard Repertoire And Genres, Angela Michelle Morgan-Thornton

Doctoral Dissertations and Projects

A standard prescribed music list exists for band, orchestra, and choral music ensembles in Texas K-12 music education. Presently, no prescribed music list exists for mariachi ensembles or degree plans in Texas at the collegiate level. This study used explanatory sequential mixed methods to examine the differences in seven Texas collegiate mariachi programs’ standard teaching and performance repertoire. The study explored the commonalities and differences in repertoire and balance of mariachi genres in instruction. The repertoire of diverse genres reflects influences associated with European, Caribbean, and Indigenous cultures and musical forms. Related issues of this study included music literacy, college …

Bullying Victimization In Middle Schools: A Quantitative Correlational Study, Corey Centwane Calhoun Sr.

Doctoral Dissertations and Projects

Bullying victimization is a very common, complex and potentially damaging form of violence among children and adolescents. Bullying is defined as unwanted, aggressive behavior, which involves a real or perceived social power imbalance. The behavior is repeated, or has the potential to be repeated, over time (therefore, the definition excludes occasional or minor incidents). Bullying victimization in schools is not only alarming, but it has now become a persuasive concern, one that should be evaluated closely by educators, parents, and policymakers in all school systems. In public schools, 1 in 10 reports at least a case of serious violent crime, …

Copd Discharge Care Bundles: An Integrative Review, Leigh Goodwin Wingo

The Role Of Embodied Metaphor In The Relationship Between Vestibular Dysfunction, Anxiety And The Self, Kaitlyn Abrams

Electronic Theses and Dissertations

There is considerable evidence that vestibular dysfunction and anxiety are correlated. Clinical and philosophical arguments suggest that a loss of sense of self, experienced through symptoms like derealization and depersonalization, might contribute to this relationship. The present study used a mixed methods approach, including Systematic Metaphor Analysis, to analyze written short answer and quantitative survey data from one hundred and thirteen participants with vestibular disorders. The Systematic Metaphor Analysis revealed several primary metaphor concepts which elucidated the connections between concrete experience and abstract concepts in vestibular dysfunction. These included metaphors of Agency, Stability, Orientation, Self-Object, and Figure-Ground. Primary metaphors for …
