GW Law Faculty Publications & Other Works

This brief paper - presented at a symposium presented for a developing nation engaged in drafting of a government procurement law - offers a diverse menu of aspirations frequently mentioned in the context of public purchasing. This paper introduces nine goals frequently identified for government procurement systems: (1) competition; (2) integrity; (3) transparency; (4) efficiency; (5) customer satisfaction; (6) best value; (7) wealth distribution; (8) risk avoidance; and (9) uniformity. The exercise of identifying aspirations is important, particularly because it is difficult for legislators or policymakers to articulate what they hope to achieve through a buying regime. While no system …

GW Law Faculty Publications & Other Works

While aggregate litigation has become an integral part of the U.S. civil justice system, it is often the cause of intense controversy among the private bar, the bench, and the academy. In 2009, the American Law Institute completed a project on the Principles of the Law of Aggregate Litigation, whose goal was to identify good procedures for handling aggregate lawsuits. The completion of these Principles spurred a host of reactions from attorneys, judges, and scholars. At a symposium hosted by The George Washington University Law School, the questions that were posed included: What is the optimal level of aggregation? When …

Privacy And Law Enforcement In The European Union: The Data Retention Directive, Francesca Bignami

GW Law Faculty Publications & Other Works

This paper examines a recent twist in EU data protection law. In the 1990s, the European Union was still primarily a market-creating organization and data protection in the European Union was aimed at rights abuses by market actors. Since the terrorist attacks of New York, Madrid, and London, however, cooperation on fighting crime has accelerated. Now, the challenge for the European Union is to protect privacy in its emerging system of criminal justice. This paper analyzes the first EU law to address data privacy in crime-fighting - the Data Retention Directive. Based on a detailed examination of the Directive's legislative …

Judicial Backlash Or Just Backlash? Evidence From A National Experiment, Donald Braman, David Fontana

GW Law Faculty Publications & Other Works

The question about whether there is a distinctive public reaction when the Supreme Court decides constitutional issues — the question of judicial backlash — permeates our discussions of constitutional law, yet we have little to no empirical research about how people think about this issue. To answer this question, we conducted an experiment before the midterm congressional elections in the fall of 2010. We hypothesized that people respond to an institution based on whether the institution is seen as supporting or threatening their cultural worldview. Half of study subjects were assigned to a condition in which a constitutional right to …

Comments On The Normative Challenge Of Environmental “Soft Law”, Dinah L. Shelton

GW Law Faculty Publications & Other Works

This paper describes the increased presence of non-binding soft law in international environmental law and begins by listing the possible uses of a “non-binding normative instrument.” Next, the paper describes the relationship between soft law and customary international law and notes that soft law may result in subsequent codification of those principles or interpret existing treaty obligations. The paper then contemplates why states are utilizing soft law in international environmental law and discusses issues regarding compliance with non-binding soft law. The paper concludes that the complicated nature of the international system prevents a prediction of the extent to which states …

Parameter Dependent Convergence Bounds And Complexity Measure For A Class Of Conceptual Hydrological Models, S. Pande, L. Bastidas, S. Bhulai, Mac Mckee

Civil and Environmental Engineering Faculty Publications

We provide analytical bounds on convergence rates for a class of hydrologic models and consequently derive a complexity measure based on the Vapnik–Chervonenkis (VC) generalization theory. The class of hydrologic models is a spatially explicit interconnected set of linear reservoirs with the aim of representing globally nonlinear hydrologic behavior by locally linear models. Here, by convergence rate, we mean convergence of the empirical risk to the expected risk. The derived measure of complexity measures a model’s propensity to overfit data. We explore how data finiteness can affect model selection for this class of hydrologic model and provide theoretical results on …

Petani Dan Pedagang: Perubahan Ekonomi Dan Agama Di Buton, Blair Palmer

Antropologi Indonesia

This article examines a dispute over proper religious practice in an all-Muslim village in Buton, Southeast Sulawesi. Traditionalists and modernists disagree over whether agricultural ceremonies involving offerings for territorial spirits should be allowed to continue. Local views on this dispute are explored with reference to the historical context of religious practice in the village, and processes of social change over the past several generations. It is argued that key social, political and economic dynamics which are relevant to the current religious dispute include the decline of agriculture in the village, the eclipsing of the Butonese Sultanate and integration into the …

Ruh Tanpa Tubuh, Tubuh Tanpa Ruh: Keterangan Tentang Mati Di Antara Universalisme Filsafati Dan Partikularisme Antropologis, Muhammad Damm

Antropologi Indonesia

Death can be understood merely as a transition from one life to the next or simply as an end of life. These two conceptions are established due to our lack in knowledge about what will happen to us after we die. In order to make any sense, both conceptions require an understanding of death (and also life) as individual matter, that the only death (and life) I experienced is always my own. Nevertheless, in the first conception death does not exterminate one’s self, while in the second conception death exterminate one’s self. However, nonexistence of any access to the first-person …

Etnografi Diri: "Mengada Dengan Dan Untuk Yang Liyan", Johanes Supriyono

This paper is an autoethnographic exploration which would like to show that culture is always in the process of constructing those that are present in various track events. Through the exposure of various stages of life and moments of encounters with Others, the author wants to confirm his argument on how culture is an arena of discourses that is continually constructed, in which also involves power relations between Self and Others. Using Abu Lughod’s approach and several contributions from philosophical thinking, the author would like to state that the theoretical journey and life trajectory is a continuity which shows the …

Evaluation Of The Physicochemical Properties And Stability Of Solid Lipid Nanoparticles Designed For The Delivery Of Dexamethasone To Tumors, Melissa Howard

University of Kentucky Doctoral Dissertations

Pre-clinical and clinical trials suggest that pre-treatment with dexamethasone (Dex) may facilitate enhanced uptake of subsequently administered chemotherapeutic agents. To reduce the side effects associated with systemic administration of Dex, solid lipid nanoparticles (SLNs) containing dexamethasone palmitate (Dex-P) were prepared as a means of achieving tumor-targeted drug delivery. These studies were aimed at evaluating the physicochemical properties and both the physiological and storage stability of the SLNs.

SLNs were prepared using nanotemplate engineering technology. Stearyl alcohol (SA) was used as the lipid phase with Brij^® 78 and Polysorbate 60 as surfactants and PEG6000 monostearate as a long-chain PEGylating agent. …

Resource Allocation And Efficient Routing In Wireless Networks, Jianjun Yang

University of Kentucky Doctoral Dissertations

In wireless networks, devices (nodes) are connected by wireless links. An important issue is to set up high quality (high bandwidth) and efficient routing paths when one node wants to send packets to other nodes. Resource allocation is the foundation to guarantee high quality connections. In addition, it is critical to handle void areas in order to set up detour-free paths. Moreover, fast message broadcasting is essential in mobile wireless networks. Thus, my research includes dynamic channel allocation in wireless mesh networks, geographic routing in Ad Hoc networks, and message broadcasting in vehicular networks.

The quality of connections in a …

This study used qualitative methods to examine if there was a connection between conflict resolution styles used with siblings in adolescence and conflict resolution styles utilized in current romantic committed relationships. The Conflict Resolution Behavior Questionnaire (Reese-Weber, & Bartle-Haring, 2003) and Gottman‟s (1994a, 1994b) couple-conflict types as adapted by Holman and Jarvis (2003) were administered to 144 participants through an online questionnaire. Analysis of the CRBQ using a multiple regression indicated participant‟s self-rating of compromise, attack, and avoidant conflict resolution styles used with siblings when an adolescent predicted current self-ratings of compromise, attack, and avoidant conflict resolution styles utilized in …

Effects Of Midstory Removal On Black Oak (Quercus Velutina) And White Oak (Quercus Alba) Regeneration, David Lee Parrott

University of Kentucky Master's Theses

The formation of dense understories in eastern forests has created low light environments that hinder the development of advance oak reproduction. Studies have shown that a midstory removal can enhance these light conditions and promote the development of competitive oak seedlings. Previous studies have been primarily focused on oaks found on productive sites, and there is little knowledge of this treatment’s potential on intermediate sites and the typically associated oak species. This study investigates the seven-year effects of midstory removal on natural and underplanted white (Quercus alba L.) and black oak (Quercus velutina L.) reproduction, as …

Perch Landing Maneuvers And Control For A Rotating-Wing Mav, Jonathan Louis Lubbers

University of Kentucky Master's Theses

This thesis addresses flight control of the perch landing maneuver for micro-aerial vehicles. A longitudinal flight model is constructed for a pigeon-sized aircraft. In addition to a standard elevator control surface, wing-rotation also considered as a non-standard actuator for increasing low-speed aerodynamic braking. Optimal state and control trajectories for the perch landing maneuver are computed using commercial software. A neighboring optimal control law is then developed and implemented in a set of flight simulations. Simulations are run with both a quasisteady and an unsteady aerodynamic model. The effectiveness of wing rotation and of the neighboring optimal control law is discussed, …

Combinatorial Aspects Of Excedances And The Frobenius Complex, Eric Logan Clark

University of Kentucky Doctoral Dissertations

In this dissertation we study the excedance permutation statistic. We start by extending the classical excedance statistic of the symmetric group to the affine symmetric group eSn and determine the generating function of its distribution. The proof involves enumerating lattice points in a skew version of the root polytope of type A. Next we study the excedance set statistic on the symmetric group by defining a related algebra which we call the excedance algebra. A combinatorial interpretation of expansions from this algebra is provided. The second half of this dissertation deals with the topology of the Frobenius complex, that …

The Effect Of Joint Mobilization On Functional Outcomes Associated With Chronic Ankle Instability, Matthew C. Hoch

University of Kentucky Doctoral Dissertations

Ankle sprains are among the most common injuries sustained by physically active individuals. Although ankle sprains are often considered innocuous in nature, a large percentage of individuals experience repetitive sprains, residual symptoms, and recurrent ankle instability following a single acute sprain; otherwise known as chronic ankle instability (CAI). In addition to repetitive ankle trauma, those with CAI experience reductions in functional capacity over the life span. This indicates that current intervention strategies for CAI are inadequate and require further investigation.

The objective of this dissertation was to explore differences in walking and running gait parameters between individuals with and without …

Lycopene And Its Potential Nutritional Role For Patients With Heart Failure, Martha J. Biddle

University of Kentucky Doctoral Dissertations

Lycopene is a antioxidant found in natural and processed foods. The connection between antioxidants and heart disease has been explored in several observational studies^1-4, yet very few investigators have examined the impact of dietary antioxidants in patient with advanced heart disease such as heart failure (HF). A novel strategy for preventing or delaying the complications of HF related to inflammation and oxidative stress may be to increase dietary lycopene.

The purpose of this dissertation was to test the impact of dietary intervention consisting of lycopene (V8® juice) on biomarkers of inflammation and oxidative stress in patients with HF; …

Biological Control Of The Black Cutworm, Agrotis Ipsilon (Lepidoptera: Noctuidae), And Endophyte Mediated Tritrophic Interactions In Turfgrass, Andrea Jeanne Bixby-Brosi

University of Kentucky Doctoral Dissertations

Components of successful pest management programs must be complementary and not antagonistic. This project examined interactions between natural enemies of the black cutworm, Agrotis ipsilon (Hufnagel), an important turfgrass pest, and host plant resistance by endophytic grass.

Agrotis ipsilon nucleopolyhedrovirus (AgipMNPV) was examined as a bio-insecticide for controlling A. ipsilon in turfgrass. Fresh (1-week-old) AgipMNPV residues killed 76−86% of neonates hatching from eggs on golf course tees, however, residual control of implanted larvae lasted no more than a few weeks. Combinations of AgipMNPV with adjuvants, such as optical brightener and lignin, failed to accelerate or extend …
