The realities of storing carbon dioxide - A response to CO2 storage capacity issues raised by Ehlig-Economides & Economides
No full textIn a recent publication, Ehlig-Economides & Economides (2010) have sought to demonstrate that carbon dioxide capture and storage (CCS) is not technically or economically feasible, based on a supposed lack of underground storage capacity. We consider this to be a serious misrepresentation of the scientific, engineering and operational facts surrounding CCS. Ehlig-Economides & Economides raise a number of storage related issues: reservoir boundaries, capacity, pressure management, storage integrity, dissolution and storage in depleted reservoirs. We take each one in turn, highlighting specific errors in the paper but also drawing attention to more general background issues. Finally, we discuss in more detail some inconsistencies in the paper surrounding the reservoir engineering calculations

The Economics of the Internet Backbone
No full textThis paper discusses the economics of the Internet backbone. The author discusses competition on the Internet backbone as well as relevant competition policy issues. In particular, he shows how public protocols, ease of entry, very fast network expansion, connections by the same Internet Service Provider ('ISP') to multiple backbones (ISP multi-homing), and connections by the same large web site to multiple ISPs (customer multi-homing) enhance price competition and make it very unlikely that any firm providing Internet backbone connectivity would find it profitable to degrade or sever interconnection with other backbones in an attempt to monopolize the Internet backbone.Technology and Industry, Regulatory Reform
Romanticism and Buddhism
No full textThis volume of Romantic Circles Praxis Series includes an editor's introduction by Mark Lussier, essays by Louise Economides, Timothy Morton, John Rudy, Dennis McCort, and a poem by Norman Dubie.
The genesis of this collection began with seemingly simple questions the editor asked of himself (and occasionally of others), and the works appearing in this volume represent answers offered by insightful and engaged colleagues: "What's going on with Buddhism during the Romantic period? Can and should academic and spiritual practices be unified and interrelated, thereby helping heal an artifically conditioned alienation common within the increasingly corporate academy?" Each one of the essays in this volume argues in different yet interrelated ways for a shared view in Buddhism and Romanticism of forms of suffering created by the self and of the fredom from suffering found in self-annihilation. Emptiness resides in plenitude and solitude, the problematic path for Buddhists and Romanticists alike. </p

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Telecommunications Regulation: An Introduction
No full textThis paper examines the justifications, history, and practice of regulation in the US telecommunications sector. We examine the impact of technological and regulatory change on market structure and business strategy. Among others, we discuss the emergence and decline of the telecom bubble, the impact on pricing of digitization and the emergence of Internet telephony. We briefly examine the impact of the 1996 Telecommunications Act on market structure and strategy in conjunction with the history of regulation and antitrust intervention in the telecommunications sector. After discussing the impact of wireless technologies, we conclude by venturing into some short term predictions. We express concern about the derailment of the implementation of the 1996 Act by the aggressive legal tactics of the entrenched monopolists (the local exchange carriers), and we point to the real danger that the intent of Congress in passing the 1996 Act to promote competition in telecommunications will not be realized. We also discuss the wave of mergers in the Telecommunications and cable industries, the telecom meltdown of 2000-2003, and issues that arose from the triennial review by the FCC of implementation of the 1996 Act.Words: telecommunications, regulation, competition, monopoly, oligopoly, Internet, broadband, DSL, unbundling, antitrust
Why Imposing New Tolls on Third-Party Content and Applications Threatens Innovation and Will Not Improve Broadband Providers’ Investment
No full textWhile some broadband providers have called Internet content and application providers free riders on their infrastructure, this is incorrect and misguided. End-users pay for their residential broadband providers for access to the Internet, and content providers pay their own ISPs for connectivity as well. However, content providers need not pay residential broadband providers’ ISPs in order to reach their customers. This feature of the Internet has been one key factor that has allowed innovation to prosper and kept barriers to entry low, as the network transport market for content and application providers functions relatively efficiently. In this paper, I consider the impact of a departure from this current system. I examine the possible impact of last-mile broadband providers’ imposing “termination fees” on third-party content providers or application providers to reach end-users. Broadband providers would engage in paid prioritization arrangements – that is, application and content providers could pay the broadband provider to have their traffic prioritized over competitors’ services. I argue that these arrangements would create inefficiency in the market and harm innovation. Because the last mile access broadband market is concentrated and consumers face switching costs, these concerns are particularly significant. Broadband providers insist that imposing these new charges will greatly improve network investment, and thus these charges are beneficial. I argue that this is not the case. Possible higher revenues from discrimination may simply be returned to shareholders and not invested. Additionally, evidence suggests networks invest more under non-discrimination requirements, and paid prioritization schemes would divert money towards managing scarcity instead of expanding capacity. Paid prioritization could even create an incentive for broadband providers to create congestion to increase the price of prioritized service.
