A Privacy-Preserving Outsourced Functional Computation Framework Across Large-Scale Multiple Encrypted Domains, Ximeng Liu, Baodong Qin, Robert H. Deng, Rongxing Lu, Jianfeng Ma

Research Collection School Of Computing and Information Systems

In this paper, we propose a framework for privacy-preserving outsourced functional computation across large-scale multiple encrypted domains, which we refer to as POFD. With POFD, a user can obtain the output of a function computed over encrypted data from multiple domains while protecting the privacy of the function itself, its input and its output. Specifically, we introduce two notions of POFD, the basic POFD and its enhanced version, in order to tradeoff the levels of privacy protection and performance. We present three protocols, named Multi-domain Secure Multiplication protocol (MSM), Secure Exponent Calculation protocol with private Base (SECB), and Secure Exponent …

Traffic Simulation Model For Port Planning And Congestion Prevention, Baoxiang Li, Kar Way Tan, Trong Khiem Tran

Research Collection School Of Computing and Information Systems

Effective management of land-side transportation provides the competitive advantage to port terminal operators in improving services and efficient use of limited space in an urban port. We present a hybrid simulation model that combines traffic-flow modeling and discrete-event simulation for land-side port planning and evaluation of traffic conditions for a number of what-if scenarios. We design our model based on a real-world case of a bulk cargo port. The problem is interesting due to complexity of heterogeneous closed-looped internal vehicles and external vehicles traveling in spaces with very limited traffic regulation (no traffic lights, no traffic wardens) and the traffic …

Hashtag Recommendation With Topical Attention-Based Lstm, Yang Li, Ting Liu, Jing Jiang, Liang Zhang

Research Collection School Of Computing and Information Systems

Microblogging services allow users to create hashtags to categorize their posts. In recent years,the task of recommending hashtags for microblogs has been given increasing attention. However,most of existing methods depend on hand-crafted features. Motivated by the successful use oflong short-term memory (LSTM) for many natural language processing tasks, in this paper, weadopt LSTM to learn the representation of a microblog post. Observing that hashtags indicatethe primary topics of microblog posts, we propose a novel attention-based LSTM model whichincorporates topic modeling into the LSTM architecture through an attention mechanism. Weevaluate our model using a large real-world dataset. Experimental results show that …

Efficient Online Summarization Of Large-Scale Dynamic Networks, Qiang Qu, Siyuan Liu, Feida Zhu, Christian S. Jensen

Research Collection School Of Computing and Information Systems

Information diffusion in social networks is often characterized by huge participating communities and viral cascades of high dynamicity. To observe, summarize, and understand the evolution of dynamic diffusion processes in an informative and insightful way is a challenge of high practical value. However, few existing studies aim to summarize networks for interesting dynamic patterns. Dynamic networks raise new challenges not found in static settings, including time sensitivity, online interestingness evaluation, and summary traceability, which render existing techniques inadequate. We propose dynamic network summarization to summarize dynamic networks with millions of nodes by only capturing the few most interesting nodes or …

From Footprint To Evidence: An Exploratory Study Of Mining Social Data For Credit Scoring, Guangming Guo, Feida Zhu, Enhong Chen, Qi Liu, Le Wu, Chu Guan

Research Collection School Of Computing and Information Systems

With the booming popularity of online social networks like Twitter and Weibo, online user footprints are accumulating rapidly on the social web. Simultaneously, the question of how to leverage the large-scale user-generated social media data for personal credit scoring comes into the sight of both researchers and practitioners. It has also become a topic of great importance and growing interest in the P2P lending industry. However, compared with traditional financial data, heterogeneous social data presents both opportunities and challenges for personal credit scoring. In this article, we seek a deep understanding of how to learn users’ credit labels from social …

Simulations For Crisis Communication: The Use Of Social Media, Siyoung Chung

Research Collection Lee Kong Chian School Of Business

Simulations have been widely used in crisis and emergency communication for practitioners but have not reached classrooms in higher education. The purpose of this study was to investigate the effects that simulations using social media have on learning of crisis communication among college students. To explore the effects, a real-time crisis simulation activity using social media are created for 132 undergraduate students enrolled at a business school. Both quantitative and qualitative data collected from pre- and post-simulation surveys are used to investigate the benefits of simulations on learning and identify the challenges the participants experienced.

Designing A Datawarehousing And Business Analytics Course Using Experiential Learning Pedagogy, Gottipati Swapna, Venky Shankararaman

Research Collection School Of Computing and Information Systems

Experiential learning refers to learning from experience or learning by doing. Universities have explored various forms for implementing experiential learning such as apprenticeships, internships, cooperative education, practicums, service learning, job shadowing, fellowships and community activities. However, very little has been done in systematically trying to integrate experiential learning to the main stream academic curriculum. Over the last two years, at the authors’ university, a new program titled UNI-X was launched to achieve this. Combining academic curriculum with experiential learning pedagogy, provides a challenging environment for students to use their disciplinary knowledge and skills to tackle real world problems and issues …

Lossy Key Encapsulation Mechanism And Its Applications, Yamin Liu, Xianhui Lu, Bao Li, Haiyang Xue

Research Collection School Of Computing and Information Systems

We introduce a new notion, lossy key encapsulation mechanism (lossy KEM), which enhances the notion of key encapsulation mechanism with lossiness, and can be more efficient than lossy trapdoor functions. We show that lossy KEM can be constructed from lossy trapdoor functions, lossy trapdoor relations, and entropic projective hashing. Using lossy KEM as a building block, several previous constructions of lossy encryption and deterministic public key encryption can be generalized and improved in efficiency.

Coherence, Richness And Cognitive Absorption In Website Design, L. Visinescu, Fiona Fui-Hoon Nah

Research Collection School Of Computing and Information Systems

Kaplan’s theory on environmental preferences can offer a holistic perspective on cognitive absorption in ecommerce website design. Drawing on Kaplan’s theory, this paper proposes that coherence and richness of a website can enhance cognitive absorption of users. The findings from our study not only support the hypotheses, but also suggest that coherence and richness can reach an optimal proportion in website design, after which they are inversely correlated.

Server-Aided Public Key Encryption With Keyword Search, Rongman Chen, Yi Mu, Guomin Yang, Fuchun Guo, Xinyi Huang, Xiaofen Wang, Yongjun Wang

Research Collection School Of Computing and Information Systems

Public key encryption with keyword search (PEKS) is a well-known cryptographic primitive for secure searchable data encryption in cloud storage. Unfortunately, it is inherently subject to the (inside) offline keyword guessing attack (KGA), which is against the data privacy of users. Existing countermeasures for dealing with this security issue mainly suffer from low efficiency and are impractical for real applications. In this paper, we provide a practical and applicable treatment on this security vulnerability by formalizing a new PEKS system named server-aided public key encryption with keyword search (SA-PEKS). In SA-PEKS, to generate the keyword ciphertext/trapdoor, the user needs to …

Infusing The Arts Into Science And The Sciences Into The Arts: An Argument For Interdisciplinary Steam In Higher Education Pathways, Christopher W. Thurley

The Transdisciplinary STEAM+ Journal

This article presents an argument for the integration of science into English courses in order to emphasize the usefulness of a Science, Technology, Education, Arts, and Mathematics (STEAM) education. The idea for this approach arose after the implementation of a divisional initiative to create learning communities with a STEM cohort of students called Student Persistence and Retention via Curricula, Cohorts, and Centralization (SPARC³). The author’s involvement in teaching a science-infused English course for this program inspired the argument that follows, which outlines why/how the sciences should learn from the humanities and why/how the humanities should learn from the sciences. The …

Gary Brewer - Dark Matter Series, Gary Brewer

The Transdisciplinary STEAM+ Journal

In the Dark Matter series of paintings I am abstracting images from NASA’s efforts to map dark matter using the Hubble Space Telescope. From these abstractions I create diaphanous veils of blue that convey a sense of movement; the movement suggests primal forces: wind, water air and fire.

The figure in the foreground is one of the elements: gold, copper, silver, which develop into a variety of fantastic shapes. The ‘elements’ which are the foundation of life on earth, are born in the heart of a star and explode out into the universe upon its death and collapse. The force …

Developing Confidence In Steam: Exploring The Challenges That Novice Elementary Teachers Face, Aaron S. Zimmerman

The Transdisciplinary STEAM+ Journal

This essay explores the challenges that novice elementary teachers may face as they attempt to enact the practices of STEAM education. Specifically, I will explore research that suggests that novice elementary teachers lack confidence in their ability to lead lessons rooted in either scientific inquiry or arts-integration. This has, I argue, clear implications for the development of STEAM education. Advocates of STEAM education must ensure that novice elementary teachers are provided with the necessary scaffolds and supports that will empower them to engage in authentic and ambitious STEAM practices.

From Stem To Steam: Students’ Beliefs About The Use Of Their Creativity, Ayse Tugba Oner, Sandra Bonorden Nite, Robert M. Capraro, Mary Margaret Capraro

The Transdisciplinary STEAM+ Journal

To be successful in a STEM career, not only STEM knowledge and skills but also creativity is required. Therefore, the arts have been integrated into STEM disciplines and subsequently designated as STEAM education (Sousa & Pilecki, 2013). One example of informal learning environments that STEAM education provided is a summer camp. In this study, middle and highs school students’ use of their creativity in the Project-based Learning (PBL) courses was examined to determine students’ belief about the use of the arts in STEM activities. The results showed that students believed that they used their creativity in eight of the nine …

Reconciling The Divide: Common Processes In Science And Arts Education, Lori A. Fulton, Jamie Simpson-Steele

The Transdisciplinary STEAM+ Journal

Many see the sciences and arts as two distinct fields – one objective the other subjective; however, we see the two having more in common than different. These commonalities formed the basis for a STEAM framework, which examines the intersections of five processes: noticing, wondering, visualizing, exploring, and communicating. This framed a professional development workshop on STEAM for elementary teachers. Here we define and explore these processes through both science and art perspectives, and share examples of how each of these processes were integrated to support learning. We believe that STEAM provides a well-rounded experience, allowing learners to make connections …

In particular, a keyword management system is provided that, based on keywords input by an advertiser, algorithmically derives a set of canonicalized IDs that represent the input keywords and near-exact formulations. The keyword management system also dynamically updates the collection of canonicalized IDs, as necessary, in response to new keywords input by the advertiser. The system is also configured to provide user feedback so as to educate the advertiser about the canonicalization of the entered keywords.

Pbis Teams Perceived Connections Between Culture And Pbis Implementation, Kathryn M. Mcphee, Kiarra Givhan

Georgia Association for Positive Behavior Support Conference

Currently in Georgia, there is a strategic plan to “improve the climate in Georgia’s school and community settings through the Positive Behavior Interventions and Supports framework.” (GaDOE, 2013, p.2). As the GaDOE’s strategic plan develops, schools are becoming more diverse with students representing a range of academic, behavioral and cultural experiences and backgrounds (Cohn & Caumont, 2016). Researchers have demonstrated that racial/ethnic disparities exist in academic achievement, discipline practices and mental health services provided in schools (e.g., Fallon et al., 2015). Thus, to improve educational experiences for all students through PBIS, considering how culture and context influence what is being …

Efficiency Of Two Sample Tests Via The T-Mean Survival Time For Analyzing Event Time Observations, Lu Tian, Haoda Fu, Stephen J. Ruberg, Hajime Uno, Lj Wei

Harvard University Biostatistics Working Paper Series

In comparing two treatments with the event time observations, the hazard ratio (HR) estimate is routinely used to quantify the treatment difference. However, this model dependent estimate may be difficult to interpret clinically especially when the proportional hazards (PH) assumption is violated. An alternative estimation procedure for treatment efficacy based on the restricted means survival time or t-year mean survival time (t-MST) has been discussed extensively in the statistical and clinical literature. On the other hand, a statistical test 1 via the HR or its asymptotically equivalent counterpart, the logrank test, is asymptotically distribution-free. In this paper, we assess the …
