Tungsten Stable Isotope Composition Of The Upper Continental Crust, Sarah E. Mazza, Richard M. Gaschnig, Roberta L. Rudnick, Thorsten Kleine

Geosciences: Faculty Publications

Tungsten (W) stable isotope data for twenty-four composites made from the fine-grained matrix of glacial diamictites, deposited between the Mesoarchean and the Paleozoic, as well as two Archean tonalite-trondhjemite-granodiorites (TTG) are used to refine the W isotope compositions (expressed as δ186W deviations from the NIST 3163 W standard) of the upper continental crust (UCC). To do this we evaluate W isotope fractionation in the diamictites as the result of both magmatic and low-temperature processes. The δ186W values of the diamictites are heterogeneous (0.017 ± 0.011 ‰, 2SE to 0.182 ± 0.007 ‰, 2SE), encompassing the range of previously published values …

BACKGROUND: Global plastic use has consistently increased over the past century with several different types of plastics now being produced. Much of these plastics end up in oceans or landfills leading to a substantial accumulation of plastics in the environment. Plastic debris slowly degrades into microplastics (MPs) that can ultimately be inhaled or ingested by both animals and humans. A growing body of evidence indicates that MPs can cross the gut barrier and enter into the lymphatic and systemic circulation leading to accumulation in tissues such as the lungs, liver, kidney, and brain. The impacts of mixed MPs exposure on …

Code review is an essential activity for ensuring the quality and maintainability of software projects. However, it is a time-consuming and often error-prone task that can significantly impact the development process. Recently, ChatGPT, a cutting-edge language model, has demonstrated impressive performance in various natural language processing tasks, suggesting its potential to automate code review processes. However, it is still unclear how well ChatGPT performs in code review tasks. To fill this gap, in this paper, we conduct the first empirical study to understand the capabilities of ChatGPT in code review tasks, specifically focusing on automated code refinement based on given …

W4-Groups: Modeling The Who, What, When And Where Of Group Behavior Via Mobility Sensing, Akansha Atrey, Camellia Zakaria, Rajesh Krishna Balan, Prashant Shenoy

Research Collection School Of Computing and Information Systems

Human social interactions occur in group settings of varying sizes and locations, depending on the type of social activity. The ability to distinguish group formations based on their purposes transforms how group detection mechanisms function. Not only should such tools support the effective detection of serendipitous encounters, but they can derive categories of relation types among users. Determining who is involved, what activity is performed, and when and where the activity occurs are critical to understanding group processes in greater depth, including supporting goal-oriented applications (e.g., performance, productivity, and mental health) that require sensing social factors. In this work, we …

Improving Automated Code Reviews: Learning From Experience, Hong Yi Lin, Patanamon Thongtanunam, Christoph Treude, Wachiraphan Charoenwet

Research Collection School Of Computing and Information Systems

Modern code review is a critical quality assurance process that is widely adopted in both industry and open source software environments. This process can help newcomers learn from the feedback of experienced reviewers; however, it often brings a large workload and stress to reviewers. To alleviate this burden, the field of automated code reviews aims to automate the process, teaching large language models to provide reviews on submitted code, just as a human would. A recent approach pre-trained and fine-tuned the code intelligent language model on a large-scale code review corpus. However, such techniques did not fully utilise quality reviews …

Beyond A Joke: Dead Code Elimination Can Delete Live Code, Haoxin Tu, Lingxiao Jiang, Debin Gao, He Jiang

Research Collection School Of Computing and Information Systems

Dead Code Elimination (DCE) is a fundamental compiler optimization technique that removes dead code (e.g., unreachable or reachable but whose results are unused) in the program to produce smaller or faster executables. However, since compiler optimizations are typically aggressively performed and there are complex relationships/interplay among a vast number of compiler optimizations (including DCE), it is not known whether DCE is indeed correctly performed and will only delete dead code in practice. In this study, we open a new research problem to investigate: can DCE happen to erroneously delete live code? To tackle this problem, we design a new approach …

Impact Of Government Outsourcing Contracts On High-Tech Vendors: An Empirical Study, Yi Dong, Nan Hu, Yonghua Ji, Chenkai Ni, Jing Xie

Research Collection School Of Computing and Information Systems

Outsourcing is an important strategic decision of high-tech firms. However, while the research has extensively studied the implications of outsourcing to high-tech clients, its impact on high-tech vendors remains underexplored. This study empirically estimates the impact of government outsourcing contracts on high-tech vendors. Employing the earnings-return analyses framework, we find that, for high-tech vendors engaged in government outsourcing contracts, the stock market places a higher value on each unit of unexpected earnings compared to other firms. Additionally, this impact becomes stronger for contracts with longer terms, for contracts outsourced by the U.S. government or by countries with better political and …

Forest Thought, Narrativity, And Counterinsurgency In Yñiga, Glenn L. Diaz

Akda: The Asian Journal of Literature, Culture, Performance

In this paper, I investigate the ways in which the tropical forest can assume the position of discourse, formal design, and textual form in fiction. I think about how, beyond its usual role as space, its vitality and various logics can facilitate a different way of storytelling, one that seeks to embody the historical resistance that the forest has long incubated. I demonstrate this by looking at the forest as a critical element in the spatio-poetics of my novel Yñiga (2022), and how its literal and conceptual manifestations--or "forest thought"--can help illuminate the ways in which history is imagined in …

Stony Brook Souvenir And Other Translated Poems, Christian Jil R. Benitez

Akda: The Asian Journal of Literature, Culture, Performance

This essay preliminary elucidates on the process of translating Jaya Jacobo’s poetry from Filipino to English. It briefly recounts the unprompted beginning of this translation work, citing it as an instance of a gift; as well the author’s general translation practice in his scholarly work, as demanded by the contemporary academic culture. Recognizing that translation is an argument in and of itself, the gesture—as it is hoped to be demonstrated here in five of Jacobo’s poems, gathered here on their comparable staging of encounters with gifts that cleave time, space, and category of matters—ultimately insists on a careful attention to …

Heat Mitigation Impacts Of Agriculture, Greenspace, And Riparian Forest In Albuquerque, New Mexico, Brennan Davis

Water Resources Professional Project Reports

Albuquerque, New Mexico, alongside the larger American desert Southwest, is already living the reality of climate change – temperatures have risen faster than the global average and, left unchecked, will continue to rise at an ever-increasing pace (NOAA 2022, Garfin et al. 2014). Alongside this disproportionate warming, the Southwest has experienced worsening drought which further stresses an already arid system (White et al. 2023, Dunbar et al. 2022). At the intersection of these changes lie a myriad of interrelated consequences for both ecosystems and communities. The urban heat island effect is one of many such consequences and is responsible for …

Civil War In Ancient Egypt? A Case Study Of The First Intermediate Period (Ca. 2120-1970 Bc), Marco Pinfari

Theses and Dissertations

The First Intermediate Period (FIP – ca. 2120-1970 BCE) is often described by Egyptologists as a period of “civil war.” In the Egyptological literature, however, little attention is paid to defining this notion (which was first introduced only in the Late Roman Republic, almost 2,000 years later) and to explaining how it could be applicable to ancient Egyptian history.

This thesis contributes to this debate by analyzing the FIP through the lenses of contemporary approaches to civil war, drawn from political science and other cognate disciplines. It first discusses how if the events of the FIP comply with contemporary definitions …

Remote Sensing Techniques To Determine Volcanic Gas Components And Fluxes: Application For Lascar, Chile And Fagradalsfjall, Iceland Volcanos., Felipe S. Rojas Vilches

Earth and Planetary Sciences ETDs

Volcanic plumes allow us to understand different aspects of a volcanic system including magma movements, dynamics, mass transfer, overall gas emissions to the atmosphere, and many processes that impact human life. However, the H₂O gas is poorly constrained due to the intrinsic difficulties of this gas, with high background values and easily dispersed/integrated into the background. In this work we study the gas emissions from Lascar volcano, and Fagradalsfjall volcano, in Chile and Iceland, respectively, using a combination of different ground-based remote sensing techniques and in situ plume measurements, we measure H₂O, SO₂, CO₂, CO, and H₂S from longer and …

Understanding Universal Design For Learning Implementation: A Hermeneutic Phenomenological Study Of The Experiences Of Higher Education Faculty And Instructional Designers, Breanne A. Kirsch

STEMPS Theses & Dissertations

Faculty face a rising challenge in supporting diverse student populations on campuses (Bastedo et al., 2013). Inclusive pedagogy, facilitated by UDL, helps alleviate learning barriers for diverse student groups (Basham & Blackorby, 2021). However, the ambiguous operational definition of UDL poses practical challenges in implementation and assessment (Diedrich, 2021), especially when it is described variably as a practice, framework, or intervention in the literature (Basham & Blackorby, 2021). This hermeneutic phenomenological study explores the meaning faculty and instructional designers ascribe to the experience of implementing UDL in higher education.

The main question is: what is the meaning that faculty and …

Unveiling Memorization In Code Models, Zhou Yang, Zhipeng Zhao, Chenyu Wang, Jieke Shi, Dongsun Kim, Donggyun Han, David Lo

Research Collection School Of Computing and Information Systems

The availability of large-scale datasets, advanced architectures, and powerful computational resources have led to effective code models that automate diverse software engineering activities. The datasets usually consist of billions of lines of code from both open-source and private repositories. A code model memorizes and produces source code verbatim, which potentially contains vulnerabilities, sensitive information, or code with strict licenses, leading to potential security and privacy issues.This paper investigates an important problem: to what extent do code models memorize their training data? We conduct an empirical study to explore memorization in large pre-trained code models. Our study highlights that simply extracting …

Out Of Sight, Out Of Mind: Better Automatic Vulnerability Repair By Broadening Input Ranges And Sources, Xin Zhou, Kisub Kim, Bowen Xu, Donggyun Han, David Lo

Research Collection School Of Computing and Information Systems

The advances of deep learning (DL) have paved the way for automatic software vulnerability repair approaches, which effectively learn the mapping from the vulnerable code to the fixed code. Nevertheless, existing DL-based vulnerability repair methods face notable limitations: 1) they struggle to handle lengthy vulnerable code, 2) they treat code as natural language texts, neglecting its inherent structure, and 3) they do not tap into the valuable expert knowledge present in the expert system. To address this, we propose VulMaster, a Transformer-based neural network model that excels at generating vulnerability repairs by comprehensively understanding the entire vulnerable code, irrespective of …

Exploiting Library Vulnerability Via Migration-Based Automated Test Generation, Zirui Chen, Xing Hu, Xin Xia, Yi Gao, Tongtong Xu, David Lo, Xiaohu Yang

Research Collection School Of Computing and Information Systems

In software development, developers extensively utilize third-party libraries to avoid implementing existing functionalities. When a new third-party library vulnerability is disclosed, project maintainers need to determine whether their projects are affected by the vulnerability, which requires developers to invest substantial effort in assessment. However, existing tools face a series of issues: static analysis tools produce false alarms, dynamic analysis tools require existing tests and test generation tools have low success rates when facing complex vulnerabilities.Vulnerability exploits, as code snippets provided for reproducing vulnerabilities after disclosure, contain a wealth of vulnerability-related information. This study proposes a new method based on vulnerability …

Towards Speedy Permission-Based Debloating For Android Apps, Thung Ferdian, Jiakun Liu, Pattarakrit Rattanukul, Shahar Maoz, Eran Toch, Debin Gao, David Lo

Research Collection School Of Computing and Information Systems

Android apps typically include many functionalities that not all users require. These result in software bloat that increases possible attack surface and app size. Common functionalities that users may not require are related to permissions that they intend to disallow in the first place. As these permissions are disallowed, their related code would never be executed and therefore can be safely removed. Existing work has proposed a solution to debloat Android apps according to the disallowed permissions. However, for large and complex applications, the debloating process could take hours, typically due the long time that may be needed to construct …

Reevaluating The Origin Of Detectable Cataclysmic Variables In Globular Clusters: Testing The Importance Of Dynamics, Liliana Rivera Sandoval, Diogo Belloni, Miriam Ramos Arevalo

Physics & Astronomy Faculty Publications

Based on the current detectable cataclysmic variable (CV) population in Galactic globular clusters (GCs), we show that there is not a clear relation between the number of sources per unit of mass and the stellar encounter rate, the cluster mass, or the cluster central density. If any, only in the case of core-collapsed GCs could there be an anticorrelation with the stellar encounter rate. Our findings contrast with previous studies where clear positive correlations were identified. Our results suggest that correlations between faint X-ray sources, from which often conclusions for the CV population are drawn, and the GC parameters considered …

Impact Of Collaborative Communities On Collective Teacher Effectiveness And Agency, Leila Barber

Dissertations

In an ever-increasing world in which change, and diversity are commonplace, leaders are often faced with the unique challenge of building Professional Learning Communities (PLCs) with unique skill sets. Building collaborative teams of educators is one way building leaders tackle this absolute task. The methods by which leaders construct teams vary widely and at times with limited direction. Teacher teams are then at the mercy of those who they are teamed with, and either reap positive rewards of collaboration, or negative discord. Teacher experiences shape the way PLCs function and how they engage with shared work with their teammates. Throughout …
