Transportation Security Framework For A Medium-Sized City, Ryan Fries, Mashrur Chowdhury, Anne Dunning
Transportation Security Framework For A Medium-Sized City, Ryan Fries, Mashrur Chowdhury, Anne Dunning
Publications
Terrorist attacks have made security preparedness unquestionably necessary in all cities. While major metropolitan areas have long recognized that their global visibility has required strong security operations, many medium-sized cities, specifically those of the U.S. and European Union, now face the need to establish transportation security frameworks for the first time. This paper assesses the resources available to help medium-sized cities begin the task of creating such systems. This assessment presents infrastructure risk assessment tools, identifies infrastructure and funding resources, and creates a process for developing a security framework to connect agencies responsible for transportation security in these metropolitan areas. …
Globalization: Winners And Losers - Talking Points, Derek Wilmott
Globalization: Winners And Losers - Talking Points, Derek Wilmott
Publications
Supporters of free trade argue that globalization increases economic prosperity as well as opportunity, especially among developing nations. Critics argue that globalization has led to the exploitation of both workers and the environment, while contributing to the destabilization of undeveloped nations. Can free trade enhance civil liberties, lead more efficient allocation of resources, and increase prosperity through globalization? Or are the critics right?

Cutting Edge: Langerin/Cd207 Receptor On Dendritic Cells Mediates Efficient Antigen Presentation On Mhc I And Ii Products In Vivo, Juliana Idoyaga, Cheolho Cheong, Koji Suda
Publications
The targeted delivery of Ags to dendritic cell (DCs) in vivo greatly improves the efficiency of Ag presentation to T cells and allows an analysis of receptor function. To evaluate the function of Langerin/CD207, a receptor expressed by subsets of DCs that frequently coexpress the DEC205/CD205 receptor, we genetically introduced OVA into the C terminus of anti-receptor Ab H chains. Taking advantage of the new L31 mAb to the extracellular domain of mouse Langerin, we find that the hybrid Ab targets appropriate DC subsets in draining lymph nodes and spleen. OVA is then presented efficiently to CD8+ and CD4 …

Ethylene Synthesis And Sensitivity In Crop Plants, Joseph F. Romagnano
Ethylene Synthesis And Sensitivity In Crop Plants, Joseph F. Romagnano
Publications
The gaseous plant hormone ethylene is a small molecule that regulates developmental change. Research was conducted in three areas: sensitivity, synthesis, and alterations to synthesis. Vegetative pea plants were more sensitive than radish plants to atmospheric ethylene. Light intensity did not affect ethylene sensitivity. Ethylene synthesis rates were measured for unstressed cotton, corn, soybean, and tomato plants. The per-plant ethylene synthesis rate ranged from 0.1-80 pmol plant-1 s-1. However, when normalized to net photosynthetic rate, this range was 1-4 µmol of ethylene synthesis per mol of CO2 uptake. Diurnal cycles in ethylene synthesis were present in all crops studied. These …

Feasibility Of Calcium Peroxide As An Oxygen Releasing Compound In Treatment Walls, Lizette R. Chevalier, Charles D. Mccann
Publications
This research investigates the use of a proprietary formulation of powdered calcium peroxide (PermeOx Plus®) as an oxygen releasing compound in a treatment wall. Laboratory scale column studies evaluated the release of oxygen and the permeability effects resulting from a treatment wall mixture of the calcium peroxide and a representative aquifer sand (40-mesh Unimin sand). The mixtures evaluated ranged from 0.1 to 1.0 percent by weight. Influent water was prepared at an average dissolved oxygen concentration of 3.1 mg/L and pumped into the treatment wall soil at a constant rate of 0.17 cm3/sec (0.53 ft3/day) to …
Lateral Exchange Of Larval Fish Between A Restored Backwater And A Large River In The East-Central Usa, Laura A. Csoboth, James E. Garvey
Lateral Exchange Of Larval Fish Between A Restored Backwater And A Large River In The East-Central Usa, Laura A. Csoboth, James E. Garvey
Publications
Exchange of larval fish between a river's main channel and its floodplain backwaters is compromised by sedimentation. Restoration projects to reduce sediment loading are being implemented in large rivers of the midwestern United States to curb backwater habitat loss and restore backwater-to-river connectivity. During 2004 and 2005, drift nets were set bidirectionally (with and against the flow) within a constructed channel between the Illinois River and an adjacent, 1,100-ha restored backwater, Swan Lake, to investigate the interplay between life history strategies and lateral drift on a diel and seasonal basis. Ambient larval density and species composition within the river and …
Movement And Habitat Selection By Invasive Asian Carps In A Large River, Kelly L. Degrandchamp, James E. Garvey, Robert E. Colombo
Movement And Habitat Selection By Invasive Asian Carps In A Large River, Kelly L. Degrandchamp, James E. Garvey, Robert E. Colombo
Publications
We evaluated the habitat use and movements of 50 adult bighead carp Hypophthalmichthys nobilis and 50 silver carp H. molitrix by means of ultrasonic telemetry during spring–summer 2004 and 2005 to gain insight into the conditions that facilitate their establishment, persistence, and dispersal in the lower Illinois River (river kilometer 0–130). Movement and habitat use were monitored with stationary receivers and boat-mounted tracking. The relative availability of four macrohabitat categories (main channel, island side channel, channel border, and connected backwater) was quantified to determine selection; discriminant function analysis was used to evaluate changes in physical characteristics within each category. A …
The Tax Treatment Of Advance Receipts, David Hasen
The Tax Treatment Of Advance Receipts, David Hasen
Publications
Under the present income tax, some advance receipts are neither taxable on receipt nor deductible on repayment, while others are taxable when received and deductible when repaid or paid for. From a purely theoretical perspective, it remains unclear why different sets of rules apply in different cases. For example, if the fact of unrestricted control over the payment compels the conclusion that it is income, then most advance receipts, including loan proceeds, should be included in income immediately. Conversely, if the presence of an offsetting liability compels the conclusion that the payment is not (yet) income, then most advance receipts, …

As the Textile Industry is the second largest industry in Egypt and as small and medium-sized enterprises (SMEs) make up a great portion of this industry therein it is essential to apply the concept of Cleaner Production for the purpose of reducing pollution. In order to achieve this goal, a case study concerned with ecofriendly stone-washing of jeans-garments was investigated. A raw material-substitution option was adopted whereby the toxic potassium permanganate and sodium sulfide were replaced by the environmentally compatible hydrogen peroxide and glucose respectively where the concentrations of both replaced chemicals together with the operating time were optimized.

How Do Securities Laws Influence Affect, Happiness, & Trust?, Peter H. Huang
How Do Securities Laws Influence Affect, Happiness, & Trust?, Peter H. Huang
Publications
This Article advocates that securities regulators promulgate rules based upon taking into consideration their impacts upon investors' and others' affect, happiness, and trust. Examples of these impacts are consumer optimism, financial stress, anxiety over how thoroughly securities regulators deliberate over proposed rules, investor confidence in securities disclosures, market exuberance, social moods, and subjective well-being. These variables affect and are affected by traditional financial variables, such as consumer debt, expenditures, and wealth; corporate investment; initial public offerings; and securities market demand, liquidity, prices, supply, and volume. This Article proposes that securities regulators can and should evaluate rules based upon measures of …

The Intriguing Federalist Future Of Reproductive Rights, Scott A. Moss, Douglas M. Raines
Publications
As the decline of Roe v. Wade inspires renewed efforts to restrict federal constitutional abortion rights, the serious shortcomings of abortion rights advocates' strategies for preserving such rights will become increasingly apparent. Continued reliance on Roe is likely to fail with an increasingly unsympathetic Supreme Court. Even abortion rights supporters have begun to criticize the decision for weak reasoning, which is difficult to remedy at this late stage of federal abortion jurisprudence. Moreover, although autonomy and gender equality arguments for abortion rights would improve upon Roe's privacy rationale, such arguments would require abrogating substantial precedent and are, therefore, of limited …
Why And How To Tax Carbon, Michael Waggoner
Why And How To Tax Carbon, Michael Waggoner
Publications
Increased concern about possible global warming due to rising levels of greenhouse gases such as carbon dioxide ("CO2") suggests the need to control emissions of CO2. This article explores a system of revenue-neutral carbon taxes as a supplement or alternative to other CO2 control systems such as subsidies, regulation, and cap-and-trade. A system of carbon taxation should be, the Article suggests, sufficiently fairer and simpler and more efficient than the other possible systems of CO2 control and that it merits serious consideration. Because the carbon tax that is suggested would be revenue neutral, it should be politically acceptable. Problems with …
Common Ground: The Case For Collaboration Between Anti-Poverty Advocates And Public Interest Intellectual Property Advocates, Deborah J. Cantrell
Common Ground: The Case For Collaboration Between Anti-Poverty Advocates And Public Interest Intellectual Property Advocates, Deborah J. Cantrell
Publications
This article examines the previously unappreciated common ground between scholars and advocates who work to eliminate poverty, and scholars and advocates who work on intellectual property issues in the public interest. The article first illustrates how scholars and advocates working on poverty and on public interest intellectual property have relied on rights talk to frame their social movements. Under the conventional narrative, the framing has accentuated differences between the movements. As the Article explains, the two movements share core principles and should recognize shared interests and goals. By developing a new model of how to view public interest movements, the …
The Next Frontier For Network Neutrality, Philip J. Weiser
The Next Frontier For Network Neutrality, Philip J. Weiser
Publications
The challenge for policymakers evaluating calls to institute some form of network neutrality regulation is to bring reasoned analysis to bear on a topic that continues to generate more heat than light and that many telecommunications companies appear to believe will just fade away. Over the fall of 2007, the hopes of broadband providers that broadband networks could escape any form of regulatory oversight were dealt a blow when it was revealed that Comcast had degraded the experience of some users of Bittorent (a peer-to-peer application) and engaged in an undisclosed form of network management. This incident, as well as …

Incorrect maintenance information has also been cited as a contributing factor in a number of recent aircraft mishaps. To date no one has studied the types of errors found in aircraft maintenance manuals published by manufacturers. The purpose of this research is to analyze Publication Change Requests (PCRs) to document the most frequently reported types of errors found in aircraft maintenance manual, to identify how errors vary across Air Transport Association (ATA) chapters, and identify the corrective actions required to address the cited problem. …
Do Off-Campus Students Use E-Books?, Pamela Grudzien, Anne Marie Casey
Do Off-Campus Students Use E-Books?, Pamela Grudzien, Anne Marie Casey
Publications
The number of electronic books (e-books) that are available is increasing rapidly. Libraries are acquiring them individually, in large groups, and as part of collections. Off-campus librarians perceive them to be the best solution to the problems and expenses related to loaning and shipping print books to off-campus students. This study looks at the usage of e-books by off-campus students at Central Michigan University (CMU) to see if usage patterns can assist librarians with e-book collection development to support off-campus programs.

Developing a sense of ourselves that would properly balance history and nature and space and time is a more difficult task than we would suspect and involves a radical reevaluation of the way we look at the world around us. Do we continue to exploit the earth or do we preserve it and preserve life? Whether we are prepared to embark on a painful intellectual journey to discover the parameters of reconciling history and nature is the question of this generation.

The Future Of 9-1-1: New Technologies And The Need For Reform, Philip J. Weiser, Dale Hatfield, Brad Bernthal
Publications
Our nation's 9-1-1 system's success to date belies the fact that its core premises will not continue to serve it effectively and it has come to a critical juncture. In particular, the balkanized nature of 9-1-1 operations that differ across jurisdictions and are supported by Byzantine funding mechanisms obscure a simple but profound development: our nation's emergency system is not keeping up with or taking advantage of technological change. Because the system continues to work and policymakers largely do not appreciate the system's technological limitations, decision makers not only fail to focus on this challenge but instead are all too …

Spectrum Policy Reform And The Next Frontier Of Property Rights, Philip J. Weiser, Dale N. Hatfield
Publications
The scarcity of wireless spectrum reflects a costly failure of regulation. In practice, large swaths of spectrum are vastly underused or used for low value activities, but the regulatory system prevents innovative users from gaining access to such spectrum through marketplace transactions. In calling for the propertyzing of swaths of spectrum as a replacement for the current command-and-control system, many scholars have wrongfully assumed the simplicity of how such a regime would work in practice. In short, many scholars suggest that spectrum property rights can easily borrow key principles from trespass law, reasoning that since property rights work well for …
