Deepjit: An End-To-End Deep Learning Framework For Just-In-Time Defect Prediction, Thong Hoang, Hoa Khanh Dam, Yasutaka Kamei, David Lo, Naoyasu Ubayashi

Research Collection School Of Computing and Information Systems

Software quality assurance efforts often focus on identifying defective code. To find likely defective code early, change-level defect prediction – aka. Just-In-Time (JIT) defect prediction – has been proposed. JIT defect prediction models identify likely defective changes and they are trained using machine learning techniques with the assumption that historical changes are similar to future ones. Most existing JIT defect prediction approaches make use of manually engineered features. Unlike those approaches, in this paper, we propose an end-to-end deep learning framework, named DeepJIT, that automatically extracts features from commit messages and code changes and use them to identify defects. Experiments …

Detect Rumors On Twitter By Promoting Information Campaigns With Generative Adversarial Learning, Jing Ma, Wei Gao, Kam-Fai Wong

Research Collection School Of Computing and Information Systems

Rumors can cause devastating consequences to individual and/or society. Analysis shows that widespread of rumors typically results from deliberately promoted information campaigns which aim to shape collective opinions on the concerned news events. In this paper, we attempt to fight such chaos with itself to make automatic rumor detection more robust and effective. Our idea is inspired by adversarial learning method originated from Generative Adversarial Networks (GAN). We propose a GAN-style approach, where a generator is designed to produce uncertain or conflicting voices, complicating the original conversational threads in order to pressurize the discriminator to learn stronger rumor indicative representations …

Support For User Generated Evolutions Of Goal Models, Boyue Caroline Hu, Alicia M. Grubb

Computer Science: Faculty Publications

Goal models are used in early phase requirements engineering to elicit stakeholders' intentions, analyze dependencies, and help stakeholders make trade-off decisions about the project and its interaction with the environment. The Evolving Intentions framework extended goal model analysis to evaluate how models change over time, by creating simulation paths showing possible evolutions of the model. More recently, we extended this analysis to allow users to explore states along the path and generate their own simulation paths. However, this approach is limited by users' ability to comprehend the state space, which grows exponentially with the size of the model. In this …

Mobilising Dissent In A Digital Age: The Curious Case Of Amos Yee, Orlando Woods

Research Collection School of Social Sciences

Political containers frame opinions. They play a formative role in establishing the terms ofinterpretation, in distinguishing between assent and dissent, and in determining the extent towhich dissent is publicly tolerated. Whilst it is by now widely acknowledged that the powerand influence of political containers has been relativised by interconnection, the effects ofmoving within and between containers – and thus mediating between different framings ofopinion – is undertheorised. Also, the enabling role of digital media in disseminating dissent,and in bringing about disproportionate reach and impact, remains understudied. Addressingthese lacunae, this paper explores the ways in which dissent can be reproduced, reframed, …

Public Cleanliness Satisfaction Survey [2018], Paulin Straughan, Mathews Mathew

Research Collection School of Social Sciences

The Singapore Management University undertook the second wave of the Public Cleanliness Satisfaction Survey (PCSS) with over 2000 Singapore resident respondents.

The 2018 wave of the PCSS continued to reflect the overall satisfaction with public cleanliness in Singapore. There was a slight increase in the proportion of Singaporeans satisfied with the overall cleanliness of public areas which they had recently used (82% in 2017 vs. 84% in 2018).

Significantly more Singaporeans are satisfied with the cleanliness of spaces after public events (63% in 2017 vs. 74% in 2018).

Satisfaction with the cleanliness of food outlets is still the lowest among …

Environmental Adaptation Of Leucaena In Western Australia – Challenges And Opportunities, Clinton K. Revell Dr, Geoff A. Moore Mr, Daniel Real, Sam Crouch

Grain and Other Field Crops Research Articles

There is considerable interest from Western Australian (WA) pastoralists on the potential role of leucaena(Leucaena leucocephala) in northern WA, where the potential area for dryland production of species of the genus Leucaenais high. Although it is highly regarded for animal production in other countries and in Queensland, leucaena is a contentious species since its status as an environmental weed currently precludes it from use on pastoral leases in the Kimberley and Pilbara regions of WA. Development of sterile/seedless forms would overcome risks of spread of the species as a weed. The key environmental constraints to growth of leucaena are likely …

Boosting The Hodrick-Prescott Filter, Peter C.B. Phillips, Zhentao Shi

Cowles Foundation Discussion Papers

The Hodrick-Prescott (HP) filter is one of the most widely used econometric methods in applied macroeconomic research. The technique is nonparametric and seeks to decompose a time series into a trend and a cyclical component unaided by economic theory or prior trend specification. Like all nonparametric methods, the HP filter depends critically on a tuning parameter that controls the degree of smoothing. Yet in contrast to modern nonparametric methods and applied work with these procedures, empirical practice with the HP filter almost universally relies on standard settings for the tuning parameter that have been suggested largely by experimentation with macroeconomic …

Necessary And Sufficient Conditions For Determinacy Of Asymptotically Stationary Equilibria In Olg Models, Alexander Gorokhovsky, Anna Rubinchik

Cowles Foundation Discussion Papers

We propose a criterion for determining whether a local policy analysis can be made in a given equilibrium in an overlapping generations model. The criterion can be applied to models with infinite past and future as well as those with a truncated past. The equilibrium is not necessarily a steady state; for example, demographic and type composition of the population or individuals’ endowments can change over time. However, asymptotically, the equilibrium should be stationary. The two limiting stationary paths at either end of the timeline do not have to be the same. If they are, conditions for local uniqueness are …

The Causal Effect Of Service Satisfaction On Customer Loyalty, Guofang Huang, K. Sudhir

Cowles Foundation Discussion Papers

We propose an instrumental-variable (IV) approach to estimate the causal effect of service satisfaction on customer loyalty, by exploiting a common source of randomness in the assignment of service employees to customers in service queues. Our approach can be applied at no incremental cost by using routine repeated cross-sectional customer survey data collected by firms. The IV approach addresses multiple sources of biases that pose challenges in estimating the causal effect using cross-sectional data: (i) the upward bias from common-method variance due to the joint measurement of service satisfaction and loyalty intent in surveys; (ii) the attenuation bias caused by …

“It All Starts With The Parents”: A Qualitative Study On Protective Factors For Drug-Use Prevention Among Black And Hispanic Girls, Ijeoma Opara, David T. Lardier, Robert Reid, Pauline Garcia-Reid

Department of Family Science and Human Development Scholarship and Creative Works

Using intersectionality theory as a theoretical framework, this qualitative study uncovered the protective factors present among black and Hispanic adolescent girls living in an urban, underresourced neighborhood in the Northeastern United States. The sample used in this study includes eight focus groups that consisted of adolescent females only (N = 57). Female participants were sampled through six youth-serving summer programs throughout the target city. The female participants were between 11 and 17 years of age, with 73% self-identifying as black (n = 45) and 26% (n = 12) as Hispanic. Thematic analysis using an intersectional approach was used to analyze …

Dna Methylation Methods For Donor Age Prediction Using Touch Dna, Emily Neverett

Master's Theses

The International Labor Organization (ILO) estimated over 30 million individuals fall victim to human trafficking each year, of which, 50% are children below the age of 16. In 2012, the ILO reported there to be 168 million child laborers worldwide, with many trafficked into hazardous conditions to manufacture consumer products that are sold in developed countries. This is a modern form of slavery with poor working conditions, no access to education, and low wages. The hidden nature of this crime, however, makes it extremely difficult to identify and locate victims of forced child labor, and thus making it challenging to …

Characterization Of Rf Signal Propagation For Wireless Sensor Network Deployed In Mountainous Environment, Bandar Mohammad Alshawi

Theses and Dissertations

Wireless sensor network (WSN) nodes, in mountainous forests, report real-time data to base stations concerning events, in which researchers and decision makers are interested in. A thorough research reveals the deficiency of any study modeling radio frequency (RF) in that environment. The lack of accurately modeling RF signal propagation in any environment can have a great impact on the network life, connectivity, and coverage. This dissertation models the loss of RF signal in the mountainous environment and demonstrates the inconsistency of theoretical models, compared to actual measurements. The models proposed in this research yield satisfactory results, and the theoretical models …

Assume-Guarantee Reasoning Using A Cyber Security Ontology, Ali Abdurhman Alfageeh

Theses and Dissertations

Design of a network is a challenging problem as it involves the integration of several complex components such as routers, servers, computers, smart devices. This is further complicated by the need to have robust security policies implemented to prevent violation of confidentiality as the networked devices interact. The design of such complex networked systems demand a more rigorous approach to the modeling and analysis, which can be inherited from the field of Software engineering. Presently, network or security engineers do not use a system/software engineering approach to design and build cybersecurity systems. Thus, we propose a system/software engineering approach to …
