Evaluating Vendor-Managed Inventory (Vmi) In Non Traditional Environments Using Simulation, Peter Southard, Scott Swenseth Dec 2008

Evaluating Vendor-Managed Inventory (Vmi) In Non Traditional Environments Using Simulation, Peter Southard, Scott Swenseth

Department of Management: Faculty Publications

This study provided empirical evidence that sufficient economic benefits could be achieved with the use of a technology-enabled vendor-managed inventory (VMI) system in a unique chain such that a firm could justify spending the money necessary to create the infrastructure to support it. The models, while based on a specific type of business, were still generic enough that the results could be generalized to many types of highly distributed, variable demand delivery systems. The study compared the costs of inventory systems used in practice by rural farm cooperatives to possible technology-enabled systems. Fuel delivery data from two agricultural cooperatives in …

Experiences Influencing Degree Completion Articulated By Doctoral Students In Education Administration., David Lee Barnett Dec 2008

Experiences Influencing Degree Completion Articulated By Doctoral Students In Education Administration., David Lee Barnett

Electronic Theses and Dissertations

Educational literature indicates that approximately half of all doctoral students persist to degree completion. The literature indicates persistence rates among the social sciences are even lower. This study examined factors influencing doctoral student persistence in education administration programs. Tinto's theory of graduate student persistence framed four research questions: Do the demographics of doctoral students persisting to degree completion in education administration differ from those not completing their programs? Do doctoral students in education administration programs articulate experiences of academic integration as influencing their persistence? Do doctoral students in education administration programs articulate experiences of social integration as influencing their persistence? …

Playing House., Tracey Bennett 1979- Dec 2008

Playing House., Tracey Bennett 1979-

Electronic Theses and Dissertations

The role of mothers, the constitution of families, and the power of their stories are the bedrock of my thesis, which is the first 90 pages of a novel entitled Playing House . In it, I hope to investigate the denotation and connotation of the words mother and family , in order to investigate the tension between the two. I hope to complicate society's assumption that a womb makes a woman a mother, and the lack of one prohibits it. Many times, we are mothered by someone other than our biological mother--sometimes for the better and sometimes not. Sometimes to …

Modeling The Relationship Between Air Quality And Intelligent Transportation System (Its) With Artificial Neural Networks., Dinesh Kumar Gupta 1965- Dec 2008

Modeling The Relationship Between Air Quality And Intelligent Transportation System (Its) With Artificial Neural Networks., Dinesh Kumar Gupta 1965-

Electronic Theses and Dissertations

Environmental or air quality impacts of Intelligent Transportation Systems (ITS) are very difficult to measure. Some researchers have attempted to quantify the effects of individual ITS application on emissions; yet, the effects of ITS as a whole on ambient air quality have not been investigated. The objective of this research was to model the relationship between ITS and ambient air quality. The multiple Artificial Neural Networks (ANN) training with the data yielded a model for predicting the air quality. In addition, the ANN made the measurement of the effect of ITS on air quality possible. Data pertaining to sixty US …

Secure Virtual Backbone-Based Power Management For Ad Hoc Networks, Hung Yuan Hsu, Ali R. Hurson Dec 2008

Secure Virtual Backbone-Based Power Management For Ad Hoc Networks, Hung Yuan Hsu, Ali R. Hurson

Electrical and Computer Engineering Faculty Research & Creative Works

Power saving is a critical issue in wireless ad hoc networks. Many of the existing energy efficient routing protocols utilize the power management feature provided by MAC layer (e.g., IEEE 802.11 PSM). the rationale behind these protocols is to power down (put in sleep) the redundant nodes that do not involve in the packets routing. to keep a low end-to-end latency and preserve the routing fidelity, a group of nodes are selected to constitute a virtual backbone throughout the network. the backbone nodes do not sleep all the time serving for the packets routing while the rest of nodes turn …

Focused Image Search In The Social Web., Zhiyong Zhang Dec 2008

Focused Image Search In The Social Web., Zhiyong Zhang

Electronic Theses and Dissertations

Recently, social multimedia-sharing websites, which allow users to upload, annotate, and share online photo or video collections, have become increasingly popular. The user tags or annotations constitute the new multimedia "meta-data". We present an image search system that exploits both image textual and visual information. First, we use focused crawling and DOM Tree based web data extraction methods to extract image textual features from social networking image collections. Second, we propose the concept of visual words to handle the image's visual content for fast indexing and searching. We also develop several user friendly search options to allow users to query …

Exhaled Nitric Oxide. An Emerging Marker Of Inflammation In Respiratory Diseases, Syed S. Habib Dec 2008

Exhaled Nitric Oxide. An Emerging Marker Of Inflammation In Respiratory Diseases, Syed S. Habib

Saudi Medical Journal

Fractional exhaled nitric oxide (FENO) is a recently introduced non invasive marker to measure inflammation and oxidative stress in the lung. The numerous roles of NO in respiratory pathophysiology have been extensively reviewed. There is contradictory evidence regarding the exact function of NO in lung diseases. In pathological states, the enzyme inducible NO synthase generates extraordinarily high concentrations of NO when the body faces an inflammatory response by attracting macrophages that generate NO and hence NO participate in host defense against specific organisms. Fractional exhaled nitric oxide measurements have been useful in asthma, chronic obstructive pulmonary disease, cystic fibrosis, and …

The Pluralistic Universe Of Law Towards A Neo-Classical Legal Pragmatism, Susan Haack Dec 2008

The Pluralistic Universe Of Law Towards A Neo-Classical Legal Pragmatism, Susan Haack

Articles

After a brief sketch of the history of philosophical pragmatism generally, and of legal pragmatism specifically (section 1), this paper develops a new, neo-classical legal pragmatism: a theory of law drawing in part on Holmes, but also on ideas from the classical pragmatist tradition in philosophy. Main themes are the "pluralistic universe" of law (section 2); the evolution of legal systems (section 3); the place of logic in the law (section 4); and the relation of law and morality (section 5).

Saving The Wto From The Risk Of Irrelevance: The Wto Dispute Settlement Mechanism As A Common Good For Rta Disputes, Henry Gao, Chin Leng Lim Dec 2008

Saving The Wto From The Risk Of Irrelevance: The Wto Dispute Settlement Mechanism As A Common Good For Rta Disputes, Henry Gao, Chin Leng Lim

Research Collection Yong Pung How School Of Law

Over the past few decades, Regional Trade Agreements (RTAs) have proliferated globally. Such proliferation of RTAs created a renewed sense of urgency for the WTO to take action in order to avoid the fate of being eclipsed into irrelevance. There are several options for coping with the challenge. Theoretically speaking, the best approach would be to heighten the level of ambition in global trade talks to reduce all trade barriers to zero so that the discriminatory effect created by RTAs could be reduced or even eliminated. In reality, such an approach would be impossible for well-known reasons. The next best …

The Myth And The Reality Of American Constitutional Exceptionalism, Stephen Gardbaum Dec 2008

The Myth And The Reality Of American Constitutional Exceptionalism, Stephen Gardbaum

Michigan Law Review

This Article critically evaluates the widely held view inside and outside the United States that American constitutional rights jurisprudence is exceptional. There are two dimensions to this perceived American exceptionalism: the content and the structure of constitutional rights. On content, the claim focuses mainly on the age, brevity, and terseness of the text and on the unusually high value attributed to free speech. On structure, the claim is primarily threefold. First, the United States has a more categorical conception of constitutional rights than other countries. Second, the United States has an exceptionally sharp public/private division in the scope of constitutional …

A Narrow Path To Diversity: The Constitutionality Of Rezoning Plans And Strategic Site Selection Of Schools After Parents Involved, Steven T. Collis Dec 2008

A Narrow Path To Diversity: The Constitutionality Of Rezoning Plans And Strategic Site Selection Of Schools After Parents Involved, Steven T. Collis

Michigan Law Review

Justice Kennedy's concurrence in Parents Involved in Community Schools v. Seattle School District Number 1 raised an important and timely constitutional issue: whether the Constitution permits K-12 public school districts not under existing desegregation orders to use site selection of new schools or rezoning plans to achieve racial diversity. Numerous scholars and journalists have interpreted Justice Kennedy's concurrence as explicitly answering the question in the affirmative. This Note argues that the opposite is true. Justice Kennedy's past jurisprudence, as well as his language in Parents Involved, favors the use of strict scrutiny. Indeed, in Parents Involved, Justice Kennedy …

Spending Clause Litigation In The Roberts Court, Samuel R. Bagenstos Dec 2008

Spending Clause Litigation In The Roberts Court, Samuel R. Bagenstos

Duke Law Journal

Throughout the Rehnquist Court's so-called federalism revolution, as the Court cut back on federal power tinder Article I and the Civil War Amendments, many commentators asserted that the spending power was next to go on the chopping block. But in the last years of the Rehnquist Court, a majority of Justices seemed to abandon the federalism revolution, and in the end, the Rehnquist Court never got around to limiting Congress's power tinder the Spending Clause. This Article contends that it is wrong to expect the Roberts Court to be so charitable about Congress's exercise of the spending power. But the …

Constitutional Secrecy: Aligning National Security Letter Nondisclosure Provisions With First Amendment Rights, Brian D. Eyink Dec 2008

Constitutional Secrecy: Aligning National Security Letter Nondisclosure Provisions With First Amendment Rights, Brian D. Eyink

Duke Law Journal

First created in the 1980s, national security letters and their nondisclosure provisions evaded judicial review until 2004. These secretive investigative tools allow federal agencies such as the FBI to compel disclosure of information about hundreds of thousands of people while also allowing the same agencies to unilaterally issue gag orders that can silence the people who receive these letters. This Note examines the nondisclosure provisions in the national security letter statutes. It argues that the nondisclosure provisions are unconstitutional prior restraints on speech and content-based speech restrictions. This Note then proposes a three-part solution that constitutionally balances the government's need …

Simulation Of Nanostructured Electrodes For Polymer Electrolyte Membrane Fuel Cells, Sanjeev M. Rao, Yangchuan Xing Dec 2008

Simulation Of Nanostructured Electrodes For Polymer Electrolyte Membrane Fuel Cells, Sanjeev M. Rao, Yangchuan Xing

Chemical and Biochemical Engineering Faculty Research & Creative Works

Aligned carbon nanotubes (CNTs) with Pt uniformly deposited on them are being considered in fabricating the catalyst layer of polymer electrolyte membrane (PEM) fuel cell electrodes. When coated with a proton conducting polymer (e.g., Nafion) on the Pt/CNTs, each Pt/CNT acts as a nanoelectrode and a collection of such nanoelectrodes constitutes the proposed nanostructured electrodes. Computer modeling was performed for the cathode side, in which both multicomponent and Knudsen diffusion were taken into account. the effect of the nanoelectrode lengths was also studied with catalyst layer thicknesses of 2, 4, 6, and 10 μm. It was observed that shorter lengths …

Political Parties In Singapore, Malaysia, And The Philippines: Reflection Of Democratic Tendencies, Ulla Fionna Dec 2008

Political Parties In Singapore, Malaysia, And The Philippines: Reflection Of Democratic Tendencies, Ulla Fionna

Makara Human Behavior Studies in Asia

This essay examines the role of political parties in different forms of government. In the three Southeast Asian countries, the different governments have distinctive methods of utilizing the parties according to their needs. The more democratic the country usually the less control the government has on the parties. The more reliant the government on its party, the more systematic its control over it. Consequently, the stronger control of government the less likely the parties would be able to reach democracy.

Fully Evolvable Optimal Neurofuzzy Controller Using Adaptive Critic Designs, Salman Mohagheghi, Ganesh K. Venayagamoorthy, Ronald G. Harley Dec 2008

Fully Evolvable Optimal Neurofuzzy Controller Using Adaptive Critic Designs, Salman Mohagheghi, Ganesh K. Venayagamoorthy, Ronald G. Harley

Electrical and Computer Engineering Faculty Research & Creative Works

A near-optimal neurofuzzy external controller is designed in this paper for a static compensator (STATCOM) in a multimachine power system. The controller provides an auxiliary reference signal for the STATCOM in such a way that it improves the damping of the rotor speed deviations of its neighboring generators. A zero-order Takagi-Sugeno fuzzy rule base constitutes the core of the controller. A heuristic dynamic programming (HDP) based approach is used to further train the controller and enable it to provide nonlinear near-optimal control at different operating conditions of the power system. Based on the connectionist systems theory, the parameters of the …

Unintended Consequences Of Repression: Alliance Formation In South Korea's Democracy Movement (1970-1979), Paul Y. Chang Dec 2008

Unintended Consequences Of Repression: Alliance Formation In South Korea's Democracy Movement (1970-1979), Paul Y. Chang

Research Collection School of Social Sciences

Research regarding the impact of repression on social movements has yielded conflicting findings; some argue that repression decreases the total quantity of protest events while others argue that it motivates protest. To move beyond this impasse, various scholars have suggested exploring how repression influences the quality of social movements. This study assesses the impact repression had on the information of alliances between different social groups participating in South Korea's democracy movement. Results from negative binomial regression analyses show that repression facilitated the formation of alliances between movement actors at a time when the overall number of protest events decreased. This …

Circumventing Congress: How The Federal Courts Opened The Door To Impeaching Criminal Defendants With Prior Convictions, Jeffrey Bellin Dec 2008

Circumventing Congress: How The Federal Courts Opened The Door To Impeaching Criminal Defendants With Prior Convictions, Jeffrey Bellin

Faculty Publications

This Article spotlights the flawed analytical framework at the heart of the federal courts’ approach to one of the most controversial trial practices in American criminal jurisprudence — the admission of prior convictions to impeach the credibility of defendants who testify. As the Article explains, the flawed approach is a byproduct of the courts’ reliance on a five-factor analytical framework to implement the governing legal standard enacted by Congress in Federal Rule of Evidence 609. Tracing the evolution of the fivefactor framework from its roots in pre-Rule 609 case law, the Article demonstrates that the courts’ reinterpretation of the framework …

Detection Of Staphylococcal Cassette Chromosome Mec Associated Dna Segments In Multiresistant Mssa And Identification Of Staphylococcus Epidermidis Ccrab4, Celine Herra, Anna Shore, Brian O’Connell,, Angela Rossney,, Derek Sullivan, Hilary Humphreys, David Coleman

Articles

Methicillin-susceptible Staphylococcus aureus (MSSA) can arise from methicillin-resistant S. aureus (MRSA) following partial or complete excision of staphylococcal cassette chromosome mec (SCCmec). This study investigated whether multiresistant MSSA isolates from Irish hospitals, where MRSA has been endemic for decades, harbor SCCmec DNA. Twenty-five multiresistant MSSA isolates recovered between 2002 and 2006 were tested for SCCmec DNA by PCR and were genotyped by multilocus sequence typing and spa typing. All isolates lacked mecA. Three isolates (12%) harbored SCCmec DNA; two of these (genotype ST8 t190) harbored a 26-kb SCCmec IID (II.3.1.2) remnant that lacked part of mecI and all of mecR1, …

Overreaction To Fearsome Risks, Cass R. Sunstein, Richard Zeckhauser Dec 2008

Overreaction To Fearsome Risks, Cass R. Sunstein, Richard Zeckhauser

Public Law and Legal Theory Working Papers

Fearsome risks are those that stimulate strong emotional responses. Such risks, which usually involve high consequences, tend to have low probabilities, since life today is no longer nasty, brutish and short. In the face of a low-probability fearsome risk, people often exaggerate the benefits of preventive, risk-reducing, or ameliorative measures. In both personal life and politics, the result is damaging overreactions to risks. We offer evidence for the phenomenon of probability neglect, failing to distinguish between high and low-probability risks. Action bias is a likely result.

Nano-Raman Spectroscopy And Surface Nanostructuring Using Near-Field Optics, Kaijun Yi Dec 2008

Nano-Raman Spectroscopy And Surface Nanostructuring Using Near-Field Optics, Kaijun Yi

Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research

To satisfy the development of nanoscience and nanotechnology, techniques to characterize and fabricate nanostructures and nanodevices are in great demand. Laser, as a unique monochromatic and coherent light source, meets the needs because it exhibits the potential to reveal some vital information of the materials. However, the applications of laser technology to nanoscience and nanotechnology are facing a severe challenge: the spatial resolution cannot be further enhanced to achieve nanometer scales due to the optical diffraction limit associated with conventional optics. In response to this challenge, near-field optics has been emerging as a new scientific area to deal with optical …
