Ancient Worries And Modern Fears: Different Roots And Common Effects Of U.S. And Eu Privacy Regulation, David Thaw, Pierluigi Perri

Articles

Much legal and technical scholarship discusses the differing views of the United States and European Union toward privacy concepts and regulation. A substantial amount of effort in recent years, in both research and policy, focuses on attempting to reconcile these viewpoints searching for a common framework with a common level of protection for citizens from both sides of Atlantic. Reconciliation, we argue, misunderstands the nature of the challenge facing effective cross-border data flows. No such reconciliation can occur without abdication of some sovereign authority of nations, that would require the adoption of an international agreement with typical tools of international …

Easing Cross-Border Communication: Mobile-Mediated Communication And Its Framework, Kyungsub Choi, Young Soo Kim

Research Collection School Of Computing and Information Systems

Communication is probably the most critical component of an organization engaged in a cross-border collaboration. Today’s smart devices substantially contribute to such communication. Combined with social media, mobile communication technologies are becoming the main platform for many core functions within organizations. In this paper, we identified seven media identifiable attributes: synchronicity (SYN), de-individuation and co-presence (DCP), accessibility readiness (ARD), cognizance of environment change (CEC), wearability-portability (WRB) modality-select (MDS) and visibility (VSB). These seven attributes significantly impact the course of mobile-mediated communication. We believe that development of a theoretical perspective that embraces the complexity of mobile-mediated communication is due in order …

Forcing Optimality And Brandt's Principle, Domenico Napoletani, Marco Panza, Daniele C. Struppa

Mathematics, Physics, and Computer Science Faculty Books and Book Chapters

We argue that many optimization methods can be viewed as representatives of “forcing”, a methodological approach that attempts to bridge the gap between data and mathematics on the basis of an a priori trust in the power of a mathematical technique, even when detailed, credible models of a phenomenon are lacking or do not justify the use of this technique. In particular, we show that forcing is implied in particle swarms optimization methods, and in modeling image processing problems through optimization. From these considerations, we extrapolate a principle for general data analysis methods, what we call ‘Brandt’s principle’, namely the …

A Novel Approach For Classifying Gene Expression Data Using Topic Modeling, Soon Jye Kho, Himi Yalamanchili, Michael L. Raymer, Amit Sheth

Kno.e.sis Publications

Understanding the role of differential gene expression in cancer etiology and cellular process is a complex problem that continues to pose a challenge due to sheer number of genes and inter-related biological processes involved. In this paper, we employ an unsupervised topic model, Latent Dirichlet Allocation (LDA) to mitigate overfitting of high-dimensionality gene expression data and to facilitate understanding of the associated pathways. LDA has been recently applied for clustering and exploring genomic data but not for classification and prediction. Here, we proposed to use LDA inclustering as well as in classification of cancer and healthy tissues using lung cancer …

Using Embedded Mixed Methods In Studying Is Phenomena: Risks And Practical Remedies With An Illustration, Xiaodan Yu, Deepak Khazanchi

Information Systems and Quantitative Analysis Faculty Publications

Drawing on lessons learned from a mixed-methods research project, we illustrate how mixed research approaches are fruitful in studying the complexities and interactions inherent in IS phenomena, which is particularly relevant when one investigates relatively new and “messy” phenomena in that many opportunities for errors and omissions can arise. Mixed-methods research designs can also prove to be valuable in exploratory or new areas of research and provide empirical evidence from multiple sources and types of data that one can truly triangulate. In this paper, we discuss the risks associated with using a specific mixed-methods research strategy (i.e., embedded mixed-methods design) …

Cybersecurity Stovepiping, David Thaw

Articles

Most readers of this Article probably have encountered – and been frustrated by – password complexity requirements. Such requirements have become a mainstream part of contemporary culture: "the more complex your password is, the more secure you are, right?" So the cybersecurity experts tell us… and policymakers have accepted this "expertise" and even adopted such requirements into law and regulation.

This Article asks two questions. First, do complex passwords actually achieve the goals many experts claim? Does using the password "Tr0ub4dor&3" or the passphrase "correcthorsebatterystaple" actually protect your account? Second, if not, then why did such requirements become so widespread? …
