Assessing Energy, Environmental, And Economic Tradeoffs In Intermodal Freight Transportation, James Winebrake, James Corbett, Aaron Falzarano Jan 2008

Assessing Energy, Environmental, And Economic Tradeoffs In Intermodal Freight Transportation, James Winebrake, James Corbett, Aaron Falzarano

Articles

This paper presents an energy and environmental network analysis model to explore tradeoffs associated with freight transport. The geospatial model uses an intermodal network built by the authors to connect various modes (rail, road, water) via intermodal terminals. Routes along the network are characterized not only by temporal and distance attributes, but also by cost, energy, and emissions attributes (including emissions of carbon dioxide, particulate matter, sulfur oxides, volatile organic compounds, and oxides of nitrogen). Decision-makers can use the model to explore tradeoffs among alternative route selection across different modal combinations, and to identify optimal routes for objectives that feature …


The M. - Σ* Project, Daniel Batcheldor Jan 2008

The M. - Σ* Project, Daniel Batcheldor

Articles

Originally published in the Memorie della Società Astronomica Italiana (The Journal of the Italian Astronomical Society. There is an intimate link between supermassive black hole (SMBH) mass (M•) and the stellar velocity dispersion (σ*) of the host bulge. This has a fundamental impact on our understanding of galaxy and SMBH formation and evolution. However, the scatter, slope and zero-point of the relation is a subject of some debate. For any progress to be made on this relation, the established values of M• and σ* must be robust. Over 50% of current M• estimates have been made using the technique of …


Emissions Tradeoffs Among Alternative Marine Fuels: Total Fuel Cycle Analysis Of Residual Oil, Marine Gas Oil, And Marine Diesel Oil, James Corbett, James Winebrake Jan 2008

Emissions Tradeoffs Among Alternative Marine Fuels: Total Fuel Cycle Analysis Of Residual Oil, Marine Gas Oil, And Marine Diesel Oil, James Corbett, James Winebrake

Articles

Worldwide concerns about sulfur oxide (SOx) emissions from ships are motivating the replacement of marine residual oil (RO) with cleaner, lower-sulfur fuels, such as marine gas oil (MGO) and marine diesel oil (MDO). Vessel operators can use MGO and MDO directly or blended with RO to achieve environmental and economic objectives. Although expected to be much cleaner in terms of criteria pollutants, these fuels require additional energy in the upstream stages of the fuel cycle (i.e., fuel processing and refining), and thus raise questions about the net impacts on greenhouse gas emissions (primarily carbon dioxide [CO2]) because of production and …


Nanotechnology In Education: Top-Down And Bottom-Up Approach, Davide Mariotti, Micheal Jackson, Elaine Lewis Jan 2008

Nanotechnology In Education: Top-Down And Bottom-Up Approach, Davide Mariotti, Micheal Jackson, Elaine Lewis

Articles

Innovative ideas and approaches for integrating nanotechnology in education are introduced and discussed. Global information and ease of access to scientific information has been considered, as one ofthe factors that may be affecting the way nanotechnology should be introduced in scholarly curricula. Two grand designs have been identified: the first relies on the redistribution of nanotechnology concepts among the existing courses/disciplines and the second promotes nanotechnology as a stand-alone discipline. Overall, it is discussed that whatever curriculum design is chosen, education of high-tech subjects has to combine a top-down with a bottom-up approach. The first serves to convey industry needs …


A High-Strehl Low-Resoultion Optical Imager (Bessel): Detection Of A 0.7(Lambda)/D Separation Binary For Mte Ground, Mary Anne Peters, Laird Close, Matt Rademacher Jan 2008

A High-Strehl Low-Resoultion Optical Imager (Bessel): Detection Of A 0.7(Lambda)/D Separation Binary For Mte Ground, Mary Anne Peters, Laird Close, Matt Rademacher

Articles

We have constructed a high-speed image stabilization system, BESSEL, which mounts to the 8-in. refractive telescope coupled to the ray white telescope at steward observatory. The high-speed tip/tilt mirror platform is controlled by an Andor electron multiplication EMCCD enabling wavefront correction at a rate exceeding 1 kHz. BESSEL achieves on-sky Strehl ratios of 98–99% at lambda) = 800 nm when the telescope aperture is stopped down to half the Fried parameter (typically D = 25.4 mm, where D is the diameter of the effective telescope aperture). Utilizing high Strehls and the technique of roll subtraction enabled BESSEL to resolve the …


Accounting Information Systems: A Business Process, Second Edition, M. Pamela Neely Jan 2008

Accounting Information Systems: A Business Process, Second Edition, M. Pamela Neely

Articles

Enabled by Enterprise Resource Planning (ERP) systems, today's businesses are moving away from a functional approach, toward an integrated approach to managing transactions. This approach requires the accountant to understand the flow of transactions through the entire business process, from order-to-cash or purchase-to-pay. These business processes are reflective of a business strategy and are supported by Accounting Information Systems (AIS) that require the management of Information Technology (IT).


Mechanism Analysis Using Implicit Constraints, George Sutherland Jan 2008

Mechanism Analysis Using Implicit Constraints, George Sutherland

Articles

This paper introduces an approach to kinematic and dynamic mechanisms analysis where one or more joints are modeled using joint component relative displacements that approximate real joint behavior. This approach allows for the simultaneous nonrecursive solution for both mechanism kinematic parameters and selected dynamic joint reaction forces. Also, for closed loop mechanisms, the approach eliminates the need for forming explicit loop closure constraint equations, so that the dynamic equations of motion (derived using either the Newtonian or Lagrangian method) have a simplified unconstrained form. The key element underlying the approach is the formation of axioms (for the standard mechanism joint …

Consumer Perceptions Of Business-To-Consumer Relationships In Electronic Retail Environments: A Means-End Chain Approach, Ryan Kearns, Neil Hair Jan 2008

Consumer Perceptions Of Business-To-Consumer Relationships In Electronic Retail Environments: A Means-End Chain Approach, Ryan Kearns, Neil Hair

Articles

This work examines the perceptions of consumers' relationships with commercial organization in electronic environments. Perceptions of a range of common electric business to consumer Internet retailers were examined using personal construct theory operationalized by means-end chain analysis. These approaches have a long tradition of being used to identify personally meaningful constructs by tracing the common attributes of their online experience with their consequences and ultimately the personal values that they pertain to. The study reveals 8 major themes that conceptualize consumers' perceptual orientations of their relationships with online retailers: personalization, engagement and experience, convenience, design/ease of use, trustworthiness, ability to …


Printing Industry Off Shoring: Perspectives From Us Based Printers, Sandra Rothenberg, Ron Hira, Zhi Tang Jan 2008

Printing Industry Off Shoring: Perspectives From Us Based Printers, Sandra Rothenberg, Ron Hira, Zhi Tang

Articles

Offshoring and offshore outsourcing, the movement of work and tasks to low-cost countries, has been increasing in scale and scope. While offshoring in the manufacturing sector has been an ongoing phenomenon for more than 40 years, more recently, examples of offshoring in services industries such as software programming, once considered non-tradable and therefore to offshoring, have emerged. The concurrent effects of the recent very rapid growth of the Indian and Chinese economies at eight to ten per cent per annum (about four times the rate of developed countries), and dramatically lower cross-border transaction costs have led many to predict significant …


Rationalization, Overcompensation And The Escalation Of Corruption In Organizations, Stelios Zyglidopoulos, Peter Fleming, Sandra Rothenberg Jan 2008

Rationalization, Overcompensation And The Escalation Of Corruption In Organizations, Stelios Zyglidopoulos, Peter Fleming, Sandra Rothenberg

Articles

An important area of business ethics research focuses on how otherwise normal and law-abiding individuals can engage in acts of corruption. Key in this literature is the concept of rationalization. This is where individuals attempt to justify past and future corrupt deeds to themselves and others. In this article, we argue that rationalization often entails a process of overcompensation whereby the justification forwarded is excessive in relation to the actual act. Such over-rationalization provides an impetus for further and more serious acts of illegality. Using a number of high profile cases, it is argued that this dynamic gap between the …


Us Missile Shield Plan Heightens European Insecurities, Tom Clonan Jan 2008

Us Missile Shield Plan Heightens European Insecurities, Tom Clonan

Articles

European Missile Shield The US Missile Defence Agency (MDA) – without recourse to NATO – is engaged in bilateral negotiations with Poland and the Czech Republic to site missile-shield silos and X-Band radar facilities in central Europe. The US intends to site 10 long-range interceptor missiles at one weapon silo - approximately the size of a football pitch - in Poland by 2011. They also intend to forward-deploy an X-Band radar station from the Marshall Islands in the Pacific to the Czech Republic in the same time period. The Russians have reacted angrily to this development with Russian Defence Minister …


Finally: An Ombudsman, Press Council And Code Of Conduct For Ireland, Michael Foley Jan 2008

Finally: An Ombudsman, Press Council And Code Of Conduct For Ireland, Michael Foley

Articles

Ireland finally produced a Press Council following many years of discussion and debate. Much of this debate surrounded the issue of reforming defamation legislation. A Press Council was seen as a concession by newspaper proprietors in return for new libel laws. The Council as finally agreed included members representing civil society as well as journalists.


Executions At Guantanamo Bay Would Mock Us Democracy, Tom Clonan Jan 2008

Executions At Guantanamo Bay Would Mock Us Democracy, Tom Clonan

Articles

This week’s announcement by the Pentagon to seek the death penalty in the case of six prisoners at Guantanamo Bay – charged with involvement in the 9/11 attacks – represents yet another step in a long-term planning process for executions at Camp Delta at the US Naval station in Cuba. US Army Regulation 190-55 has for some time allowed for military executions by lethal injection. Until recently however, precedent within US martial law has identified Fort Leavenworth in Kansas as the location for military executions – a location which in theory, would place the condemned prisoner within the jurisdiction of …


Eu's Military Ambitions Clear: Lisbon Treaty Analysis, Tom Clonan Jan 2008

Eu's Military Ambitions Clear: Lisbon Treaty Analysis, Tom Clonan

Articles

Many of those who oppose the Lisbon Treaty cite its European Security and Defence Policy (ESDP) and Common Security and Foreign Policy (CSFP) provisions as cause for concern in terms of how they might impact on Irish neutrality or serve to create a pan-European army to rival NATO. Those clauses of the Lisbon Treaty which address security and defence issues are worthy of debate, and may cause concern in some quarters. They do not however impact directly on Irish neutrality. Nor do they amount to a charter for the creation of a standing European army. Much of what the Lisbon …


Negroponte: Legacy Of Bush Administration For Obama, Tom Clonan Jan 2008

Negroponte: Legacy Of Bush Administration For Obama, Tom Clonan

Articles

Muntader al-Zaidi’s words as he threw his shoes at the outgoing US President in the Green Zone in Baghdad this week may well become the epitaph for George Bush’s disastrous invasion of Iraq. It was a hugely symbolic act and was reminiscent of the beating with shoes by angry Iraqis of Saddam’s statue – toppled by US troops as the Iraqi capital fell to US forces - on the 9th of April 2003. Hurling his shoes at President Bush, al-Zaidi declared his act a ‘gift’ from the Iraqis, ‘a farewell kiss you dog’. Al-Zaidi concluded his rebuke of President Bush …


Russia Fires Shot Across Bows Of Eu, Us And Nato, Tom Clonan Jan 2008

Russia Fires Shot Across Bows Of Eu, Us And Nato, Tom Clonan

Articles

As both houses of the Russian parliament call upon President Medvedev to support Abkhazia and South Ossetia’s right to self determination, Russian military commanders would appear to be consolidating a so-called ‘buffer zone’ within Georgia proper. According to Moscow, a battalion of 272 Russian troops will occupy eight ‘forward’ positions up to 15km within Georgia proper along its borders with Abkhazia and South Ossetia. A further 250 Russian troops are set to be deployed to the rear of these positions to perform ‘logistics, engineering and support’ functions. As Russia consolidates its foothold in Georgia, serious questions arise as to the …


Separate Loci Underlie Resistance To Root Infection And Leaf Scorch During Soybean Sudden Death Syndrome, Samreen Kazi, Jeffry Shultz, Jawad Afzal, J. Johnson, V. N. Njiti, David A. Lightfoot Jan 2008

Separate Loci Underlie Resistance To Root Infection And Leaf Scorch During Soybean Sudden Death Syndrome, Samreen Kazi, Jeffry Shultz, Jawad Afzal, J. Johnson, V. N. Njiti, David A. Lightfoot

Articles

Soybean [Glycine max (L.) Merr.] cultivars show differences in their resistance to both the leaf scorch and root rot of sudden death syndrome (SDS). The syndrome is caused by root colonization by Fusarium virguliforme (ex. F. solani f. sp. glycines). Root susceptibility combined with reduced leaf scorch resistance has been associated with resistance to Heterodera glycines HG Type 1.3.6.7 (race 14) of the soybean cyst nematode (SCN). In contrast, the rhg1 locus underlying resistance to Hg Type 0 was found clustered with three loci for resistance to SDS leaf scorch and one for root infection. The aims of this study …


Technology-Aided Participative Methods In Environmental Assessment: An International Perspective, Ainhoa Gonzalez, Alan Gilmer, Ronan Foley, John Sweeney, John Fry Jan 2008

Technology-Aided Participative Methods In Environmental Assessment: An International Perspective, Ainhoa Gonzalez, Alan Gilmer, Ronan Foley, John Sweeney, John Fry

Articles

Provisions for citizen involvement in the assessment of potential environmental effects of certain plans, programmes and projects are present in current legislation. An international survey revealed that public participation is common practice in European and some other countries worldwide. However, a number of issues are observed to affect public involvement in EIA/SEA processes and expert opinion differs when evaluating the effectiveness of existing participative methods. Results suggest that technology-aided methods can improve traditional participation processes. In particular, GIS has the potential to increase community knowledge and enhance involvement by communicating information more effectively. Variable accessibility to technology and data quality …

Simplified Explanation Of Pneumatic Tire Behavior, George Sutherland Jan 2008

Simplified Explanation Of Pneumatic Tire Behavior, George Sutherland

Articles

This paper develops a simple model for the behavior of a pneumatic tire when vertically loaded. The model is based on the behavior of a thick-skinned spherical membrane (like a basketball) being compressed between two flat plates. The model is reasonably accurate for bicycle, motorcycle, truck, general purpose, and early model automobile tires which all have a circular cross-section. However modern automobile tires have a wide aspect ratio when unloaded, have unloaded line contact with the ground across the tread width, and have relatively stiff sidewalls that contribute to the tire’s load carrying capability (and in the case of run-flat …
