The Rise Of Private Equity Media Ownership In The United States: A Public Interest Perspective, Matthew Crain

Publications and Research

This article examines the logic, scope, and implications of the influx of private equity takeovers in the United States media sector in the last decade. The strategies and aims of private equity firms are explained in the context of the financial landscape that has allowed them to flourish; their aggressive expansion into media ownership is outlined in detail. Particular attention is paid to the public interest concerns raised by private equity media ownership relating to the frenzied nature of the buyout market, profit maximization strategies, and the heavy debt burdens imposed on acquired firms. The article concludes with discussion of …

Service Level Agreement In Cloud Computing, Pankesh Patel, Ajith H. Ranabahu, Amit P. Sheth

Kno.e.sis Publications

Cloud computing that provides cheap and pay-as-you-go computing resources is rapidly gaining momentum as an alternative to traditional IT Infrastructure. As more and more consumers delegate their tasks to cloud providers, Service Level Agreements(SLA) between consumers and providers emerge as a key aspect. Due to the dynamic nature of the cloud, continuous monitoring on Quality of Service (QoS) attributes is necessary to enforce SLAs. Also numerous other factors such as trust (on the cloud provider) come into consideration, particularly for enterprise customers that may outsource its critical data. This complex nature of the cloud landscape warrants a sophisticated means of …

Determining The Best K For Clustering Transactional Datasets: A Coverage Density-Based Approach, Hua Yan, Keke Chen, Ling Liu

Kno.e.sis Publications

The problem of determining the optimal number of clusters is important but mysterious in cluster analysis. In this paper, we propose a novel method to find a set of candidate optimal number Ks of clusters in transactional datasets. Concretely, we propose Transactional-cluster-modes Dissimilarity based on the concept of coverage density as an intuitive transactional inter-cluster dissimilarity measure. Based on the above measure, an agglomerative hierachical clustering algorithm is developed and the Merge Dissimilarity Indexes, which are generated in hierachical cluster merging processes, are used to find the candidate optimal number Ks of clusters of transactional data. Our experimental results on …

Cookie Monsters: Seeing Young People’S Hacking As Creative Practice, Gregory T. Donovan, Cindi Katz

Publications and Research

This paper examines the benefits and obstacles to young people’s open-ended and unrestricted access to technological environments. While children and youth are frequently seen as threatened or threatening in this realm, their playful engagements suggest that they are self-possessed social actors, able to negotiate most of its challenges effectively. Whether it is proprietary software, the business practices of some technology providers, or the separation of play, work, and learning in most classrooms, the spatial-temporality of young people’s access to and use of technology is often configured to restrict their freedom of choice and behavior. We focus on these issues through …

Social Implications Of Fearing Terrorism. A Report On Australian Responses To The Images, Anne Aly, Lelia Green

"Exploding Media Myths : Misrepresenting Australia?" - Forum

On 20 November 2008, 29 participants came together for the Exploding Media Myths: Misrepresenting Australia Forum at the University of NSW in Sydney. The Forum was designed to bring together keynote speakers, academics, policy makers, the media and community to discuss the findings of an Australian Research Council Discovery Project, Australian Responses to the Images and Discourses of Terrorism and the Other: Establishing a Metric of Fear. Over the course of the day, the participants discussed a range of themes relevant to the media and its representation of Australia and Australian values in the context of increased incidences of …

Using Sunflower Plots And Classification Trees To Study Typeface Legibility, Edgar C. Merkle, Barbara S. Chaparro

Publications

This article describes the application of sunflower plots and classification trees to the study of onscreen typeface legibility. The two methods are useful for describing high-dimensional data in an intuitive manner, which is crucial for interacting with both the typographers who design the typefaces and the practitioners who must make decisions about which typeface to use for specific applications. Furthermore, classification trees help us make specific recommendations for how much of a character attribute is “enough” to make it legible. We present examples of sunflower plots and classification trees using data from a recent typeface legibility experiment, and we present …

This study attempts to find which online news sites are widely used by this group, based on the credibility of online news adopted among undergraduate and graduate students at the University of Nevada, Las Vegas (UNLV), in which demographic …

Offering Rss Feeds: Does It Help To Gain Competitive Advantage?, Dan Ma

Research Collection School Of Computing and Information Systems

Nowadays, many Websites have adopted the really simple syndication (RSS) technology to deliver online content to visitors. In this paper, I build an analytical model to examine how the offering of RSS feeds impact the number of visitors, total traffic load, and profit of Websites in a competitive setting. I show that although RSS can always attract more visitors, it may reduce the Website's profit. Interestingly, in a competitive market there are cases that the RSS feeds hurt the offering Website but benefit the competing Website instead. The conditions under which these will happen are derived. I also study the …
