After The Avalanche: The Post-Snowden Intelligence Politics Between The United States, The United Kingdom, And Germany, Jobel Kyle P. Vecino 2016 University of California - Berkeley

After The Avalanche: The Post-Snowden Intelligence Politics Between The United States, The United Kingdom, And Germany, Jobel Kyle P. Vecino

Claremont-UC Undergraduate Research Conference on the European Union

The revelations of PRISM and XKeyscore by ex-National Security Agency (NSA) analyst Edward Snowden resulted in arguably the largest intelligence leak so far in the 21st century. The leak revealed that the NSA was working with the British Government Communications Headquarters (GCHQ) on surveillance and data collection of individuals throughout Europe. Similarly, the NSA also colluded with the German Federal Intelligence Service (BND) on similar data collection and surveillance activities. Whereas the British government reacted relatively benignly to the revelations despite cries of government abuse, the German government reacted negatively to the revelations, eventually opening a rift between Washington ...

The Design And Validation Of A Wireless Bat-Mounted Sonar Recording System, Jeremy Joseph Langford 2016 University of Tennessee, Knoxville

The Design And Validation Of A Wireless Bat-Mounted Sonar Recording System, Jeremy Joseph Langford

Masters Theses

Scientists studying the behavior of bats monitor their echolocation calls, as their calls are important for navigation and feeding, but scientist are typically restricted to ground-based recording. Recording bat calls used for echolocation from the back of the bat as opposed to the ground offers the opportunity to study bat echolocation from a vantage otherwise only offered to the bats themselves. However, designing a bat mounted in-flight audio recording system, (bat-tag), capable of recording the ultra-sound used in bat echolocation presents a unique set of challenges. Chiefly, the bat-tag must be sufficiently light weight as to not overburden the bat ...


Topology Design And Delay Control For Communication Networks In Smart Grid, Xiaodong Wang 2016 University of Tennessee, Knoxville

Topology Design And Delay Control For Communication Networks In Smart Grid, Xiaodong Wang

Doctoral Dissertations

Stability is a critical concern in the design and maintenance of power systems. Different approaches have been proposed for the analysis of power grid stability in various scenarios depending on small or large perturbations and the speed of the phenomenon of interest. In this work, we consider the power grid as a group of flocking birds, as synchronization is the key issue in both contexts. The framework of partial difference equation (PdE) is used to analyze the system stability, when designing the communication network of the power grid network for conveying measurements between different power stations. Both the cases where ...


User Identity Linkage By Latent User Space Modelling, Xin MU, Feida ZHU, Ee-Peng LIM, Jing XIAO, Jianzong WANG, Zhi-Hua ZHOU 2016 Singapore Management University

User Identity Linkage By Latent User Space Modelling, Xin Mu, Feida Zhu, Ee-Peng Lim, Jing Xiao, Jianzong Wang, Zhi-Hua Zhou

Research Collection School Of Information Systems

User identity linkage across social platforms is an important problem of great research challenge and practical value. In real applications, the task often assumes an extra degree of difficulty by requiring linkage across multiple platforms. While pair-wise user linkage between two platforms, which has been the focus of most existing solutions, provides reasonably convincing linkage, the result depends by nature on the order of platform pairs in execution with no theoretical guarantee on its stability. In this paper, we explore a new concept of “Latent User Space” to more naturally model the relationship between the underlying real users and their ...

Climbing Up Cloud Nine: Performance Enhancement Techniques For Cloud Computing Environments, Mohamed Abusharkh

Electronic Thesis and Dissertation Repository

With the transformation of cloud computing technologies from an attractive trend to a business reality, the need is more pressing than ever for efficient cloud service management tools and techniques. As cloud technologies continue to mature, the service model, resource allocation methodologies, energy efficiency models and general service management schemes are not yet saturated. The burden of making this all tick perfectly falls on cloud providers. Surely, economy of scale revenues and leveraging existing infrastructure and giant workforce are there as positives, but it is far from straightforward operation from that point. Performance and service delivery will still depend on ...

Crowdsourcing Management Education Assessment, Owen P. Hall Jr, Charla Griffy-Brown

Journal of International Technology and Information Management

Assessment is now at the center of the new business education zeitgeist. This focus is the direct result of feedback from the business community regarding the growing gap between their needs and graduates from many business schools. Recently this divide has fallen under even closer scrutiny because of increasing student debt and the growing controversy over return-on- investment. Today business leaders are looking for web-savvy, problem-solving graduates. To this end, AACSB and regional accrediting bodies are calling for the adoption of comprehensive collaborative learning strategies to better align graduates’ skill sets with the real needs of business.

Privacy And The Information Age: A Longitudinal View, Charles E. Downing 2016 Northern Illinois University

Privacy And The Information Age: A Longitudinal View, Charles E. Downing

Journal of International Technology and Information Management

As information systems and data storage capacity become increasingly sophisticated, an important ethical question for organizations is “What can/will/should be done with the personal information that has been and can be collected?” Individuals’ privacy is certainly important, but so is less costly and more targeted business processes. As this conflict intensifies, consumers, managers and policy makers are left wondering: What privacy principles are important to guide organizations in self-regulation? For example, do consumers view the five rights originally stated in the European Data Protection Directive as important? Comprehensive? Is there a product discount point where consumers would forsake ...

An Empirical Investigation On Ceo Turnover In It Firms And Firm Performance, Peiqin Zhang, David Wierschem, Francis A. Mendez Mediavilla, Keejae P. Hong

Journal of International Technology and Information Management

Drawn upon upper echelon theory and organizational theory, this research proposes to examine the impact of CEO turnover in IT firms on firm performance in terms of both sustainable accounting performance and market performance. We find that CEO turnover is a significant determinant of firm performance, especially in IT firms. This paper contributes to the IS literature by investigating the CEO turnover impact in IT firms compared to other industries. This study also has practical implications by providing the guideline for IT firms on the CEO turnover policy. Such firms should place additional emphasis on their succession planning efforts.

Journal of International Technology and Information Management

Facebook is one of the world’s leading social networking sites. It is pervasive in students’ lives and can impact their academic careers in a variety of ways. However, little research exists evaluating the use of Facebook in minority academic settings. An early step in this direction is to gain an understanding of how different student demographic groups use Facebook. An interest in further assessment of Facebook’s role in diverse segments of academia motivates the collection and analysis of Facebook-related data from minority serving institutions such as Historically Black Colleges or Universities (HBCUs) and Hispanic Serving Institutions (HSIs). This ...


The Fcc And The “Pre-Internet”, John Blevins 2016 Loyola University School of Law - New Orleans

The Fcc And The “Pre-Internet”, John Blevins

Indiana Law Journal

Network neutrality has dominated broadband policy debates for the past decade. While important, network neutrality overshadows other policy levers that are equally important to the goals of better, cheaper, and more open broadband service. This lack of perspective has historical precedent—and understanding this history can help refocus today’s policy debate. In the 1960s and 1970s, telephone companies threatened the growth of the nascent data industry. The FCC responded with a series of rulemakings known as the “Computer Inquiries” proceedings. In the literature, Computer Inquiries enjoys hallowed status as a key foundation of the Internet’s rise.

El Capitán: Cal Poly Rose Float Digital Drive System, Gregory Raffi Baghdikian

Computer Engineering

In today’s world of smartphones, self-driving cars, and internet-connected coffee makers, it seems as if computers are contained in everything around us. These “embedded systems” have become critical components of our lives, improving everything about the things they control, from cost, to speed, to simplicity. One area that embedded systems has hardly gained a foothold is in the world of floatbuilding. Most of the floats in the Tournament of Roses Parade, including the one built jointly by Cal Poly San Luis Obispo and Cal Poly Pomona, are technologically very simple, using mostly analog components and rudimentary discrete digital logic ...
