In this complex and ever changing operating environment, there remains an essential need to better understand how these developments, and …

Economically Disadvantaged Minority Girls' Knowledge And Perceptions Of Science And Engineering And Related Careers, Hui-Hui Wang, Barbara L. Billington

Journal of Extension

This article addresses economically disadvantaged minority girls' knowledge and perceptions of science and engineering and the influence of their experiences with science, technology, engineering, and mathematics (STEM) on their choices for future careers. We interviewed three girls who participated in a 4-H–led gender-inclusive STEM program. Our findings suggest that the girls lacked opportunities to learn STEM in out-of-school settings and that they had very limited knowledge about STEM professions. They did not associate their job aspirations as being related to STEM, even though they were. To better prepare such girls to engage in STEM, educators need to provide long-term interventions …

Lower Prairie Creek Project Redwood National Park "Forest Owners", Susie Van Kirk

Susie Van Kirk Papers

"This file addresses forest ownerships, using deeds, patents, and maps in the Humboldt County Recorder’s Office, Eureka Courthouse. Pretty boring to wade through, these records, nonetheless, document how the public domain of northwestern California—the ancient redwood forests—came to be concentrated in the hands of timber companies. ... Land in the Lower Prairie Creek Project area (plus much, much other forest lands) was obtained through fraudulent patents and deed transactions involving David Evans and his associates for transfer to Scottish investors and eventually to “legitimate” timber companies. The end result, of course, is that what once belonged to indigenous people and …

Identity establishment consists of fused identity, layered identity, attributed identity, and value-focused identity. The use of power …

Weak Convergence To Stochastic Integrals For Econometric Applications, Hanying Liang, Peter C. B. Phillips, Hanchao Wang, Qiying Wang

Research Collection School Of Economics

Limit theory involving stochastic integrals is now widespread in time series econometrics and relies on a few key results on functional weak convergence. In establishing such convergence, the literature commonly uses martingale and semimartingale structures. While these structures have wide relevance, many applications involve a cointegration framework where endogeneity and nonlinearity play major roles and complicate the limit theory. This paper explores weak convergence limit theory to stochastic integral functionals in such settings. We use a novel decomposition of sample covariances of functions of I (1) and I (0) time series that simplifies the asymptotics and our limit results for …

Panel Data Models With Interactive Fixed Effects And Multiple Structural Breaks, Degui Li, Junhui Qian, Liangjun Su

Research Collection School Of Economics

In this article, we consider estimation of common structural breaks in panel data models with unobservable interactive fixed effects. We introduce a penalized principal component (PPC) estimation procedure with an adaptive group fused LASSO to detect the multiple structural breaks in the models. Under some mild conditions, we show that with probability approaching one the proposed method can correctly determine the unknown number of breaks and consistently estimate the common break dates. Furthermore, we estimate the regression coefficients through the post-LASSO method and establish the asymptotic distribution theory for the resulting estimators. The developed methodology and theory are applicable to …

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 …

Iterated Random Oracle: A Universal Approach For Finding Loss In Security Reduction, Fuchun Guo, Willy Susilo, Yi Mu, Rongmao Chen, Jianchang Lai, Guomin Yang

Research Collection School Of Computing and Information Systems

The indistinguishability security of a public-key cryptosystem can be reduced to a computational hard assumption in the random oracle model, where the solution to a computational hard problem is hidden in one of the adversary’s queries to the random oracle. Usually, there is a finding loss in finding the correct solution from the query set, especially when the decisional variant of the computational problem is also hard. The problem of finding loss must be addressed towards tight(er) reductions under this type. In EUROCRYPT 2008, Cash, Kiltz and Shoup proposed a novel approach using a trapdoor test that can solve the …

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 …

Metroeye: Smart Tracking Your Metro Rips Underground, Weixi Gu, Ming Jin, Zimu Zhou, Costas J. Spanos, Lin Zhang

Research Collection School Of Computing and Information Systems

Metro has become the first choice of traveling for tourists and citizens in metropolis due to its efficiency and convenience. Yet passengers have to rely on metro broadcasts to know their locations because popular localization services (e.g. GPS and wireless localization technologies) are often inaccessible underground. To this end, we propose MetroEye, an intelligent smartphone-based tracking system for metro passengers underground. MetroEye leverages low-power sensors embedded in modern smartphones to record ambient contextual features, and infers the state of passengers (Stop, Running, and Interchange) during an entire metro trip using a Conditional Random Field (CRF) model.

The rapid ageing population is posing challenges to many countries all over the world, particularly in the provision of care to the growing number of elderly who are living alone. Allowing the elderly to age-in-place, i.e., live safely and independently in the comfort of their own homes is a model that can potentially address the resource constraint in health and community care faced by many nations. To make this model a reality and provide appropriate and timely care to the elderly, unobtrusive eldercare monitoring systems (EMS) are being deployed in real homes to continuously monitor the activity of the elderly. …

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 …

Bad Language: A Study Of Structural Violence Through Language Policies In Australia, Dylan M. Howes

Capstone Projects and Master's Theses

By situating the heart of Aboriginal culture in the ability to understand and speak Aboriginal languages, I intend to prove that language education policies have caused damage within Aboriginal communities. In order to find and record the damage done by these policies I will use Johan Galtung’s theory of structural violence, which states that large social structures create indirect sources of violence by withholding resources and power from certain groups. Specifically, I will start by providing a brief history of Aboriginal culture and their languages. Then I will analyze language policies, policy analysis, and my own experiences in order to …
