Bespoke Custom, Edward T. Swaine

GW Law Faculty Publications & Other Works

Curtis Bradley and Mitu Gulati’s stimulating article, “Withdrawing from International Custom,” argues for a view of customary international law (CIL) in which unilateral exit rights may be revitalized. This response suggests that Bradley and Gulati’s understanding of the intellectual history of CIL is contestable and that, they tend both to understate the novelty of their approach and overstate the rigidity of the views to which they react. Their tentativeness in endorsing exit options makes it difficult to assess the normative implications of their position, but their argument notably lacks a comprehensive consideration of alternative lawmaking forms.

Design And Evaluation Of A Suspension Seat To Reduce Vibration Exposure Of Subway Operators: A Case Study, Pierre Marcotte, Sylvie Beaugrand, Jérôme Boutin, Christian Larue

Études primaires

Subway operators have complained about discomfort caused by whole-body vibration. To address this problem, a suspension seat with extensive ergonomic features has been adapted to the confined space of the subway operator cab. The suspension was modified from an existing suspension in order to reduce the dominant frequency of the subway vertical vibration (2.4 Hz). The suspension seat has been extensively tested on a vertical hydraulic shaker. These tests have shown that the SEAT value was lower for a higher vibration level, for higher subject weight, and for the suspension adjusted at median height. The seat also produces a lower …

Rank-Based Attachment Leads To Power Law Graphs, Jeannette Janssen, Paweł Prałat

Faculty & Staff Scholarship

We investigate the degree distribution resulting from graph generation models based on rank-based attachment. In rank-based attachment, all vertices are ranked according to a ranking scheme. The link probability of a given vertex is proportional to its rank raised to the power ―α, for some α ∈ (0, 1). Through a rigorous analysis, we show that rank-based attachment models lead to graphs with a power law degree distribution with exponent 1 + 1/α whenever vertices are ranked according to their degree, their age, or a randomly chosen fitness value. We also investigate the case where the ranking is based on …

Dem Development From Ground-Based Lidar Data: A Method To Remove Non-Surface Objects, Maneesh Sharma, Ginger B. Paige, Scott N. Miller

Faculty & Staff Scholarship

Topography and land cover characteristics can have significant effects on infiltration, runoff, and erosion processes on watersheds. The ability to model the timing and routing of surface water and erosion is affected by the resolution of the digital elevation model (DEM). High resolution ground-based Light Detecting and Ranging (LiDAR) technology can be used to collect detailed topographic and land cover characteristic data. In this study, a method was developed to remove vegetation from ground-based LiDAR data to create high resolution DEMs. Research was conducted on intensively studied rainfall–runoff plots on the USDA-ARS Walnut Gulch Experimental Watershed in Southeast Arizona. LiDAR …

Thresholds And Tolerance Of Physical Pain Among Young Adults Who Self-Injure, Katrina Mccoy, William Fremouw, Daniel W. Mcneil

Faculty & Staff Scholarship

Prevalence rates of nonsuicidal self-injury among college students range from 17% to 38%. Research indicates that individuals with borderline personality disorder who self-injure sometimes report an absence of pain during self-injury. Furthermore, self-injury in the absence of pain has been associated with more frequent suicide attempts. The present study examined pain thresholds and tolerance among 44 college students (11 who engaged in self-injury and 33 who did not). Pain thresholds and tolerance were measured using an algometer pressure device that was used to produce pain in previous laboratory research. Participants who engaged in self-injury had a higher pain tolerance than …

Change Detection Accuracy And Image Properties: A Study Using Simulated Data, Abdullah Almutairi, Timothy A. Warner

Faculty & Staff Scholarship

Simulated data were used to investigate the relationships between image properties and change detection accuracy in a systematic manner. The image properties examined were class separability, radiometric normalization and image spectral band-to-band correlation. The change detection methods evaluated were post-classification comparison, direct classification of multidate imagery, image differencing, principal component analysis, and change vector analysis. The simulated data experiments showed that the relative accuracy of the change detection methods varied with changes in image properties, thus confirming the hypothesis that caution should be used in generalizing from studies that use only a single image pair. In most cases, direct classification …

Spatially Heterogeneous Estimates Of Fire Frequency In Ponderosa Pine Forests Of Washington, Usa, James T. Kernan, Amy E. Hessl

Faculty & Staff Scholarship

Many fire history studies have evaluated the temporal nature of fire regimes using fire interval statistics calculated from fire scars. More recently, researchers have begun to evaluate the spatial properties of past fires as well. In this paper, we describe a technique for investigating spatio-temporal variability using a geographic information system (GIS). We used a dataset of fire-scarred trees collected from four sites in eastern Washington, USA, ponderosa pine (Pinus ponderosa C. Lawson) forests. The patterns of past fires recorded by individual trees (points) were converted to two-dimensional representations of fire with inverse distance weighting (IDW) in a GIS. …

Development Of A Laser-Induced Breakdown Spectrometer For Lead-Free Gunshot Residue Analysis, Ryan Alexander Gregg

Honors Theses

Research has demonstrated that Laser‐Induced Breakdown Spectroscopy (LIBS) can be used as an effective method of screening for the common elemental components in gunshot residue. Barium (Ba), lead (Pb), and antimony (Sb) make up the primer cap of most ammunition involved in forensic gunshot residue analysis. Recently, ammunition manufacturers have started producing and popularizing ammunition with zinc (Zn), titanium (Ti), and gadolinium (Gd) primer components that are non‐toxic to the environment. This paper discusses the development of the Ole Miss Department of Chemistry and Biochemistry's first LIBS instrument for forensic analysis of lead‐free using Gd as a tracer element for …

Developing The Techniques For Raman, Surface-Enhanced Raman Scattering (Sers), And Fluorescence Spectroscopies Of Organic Molecules In Isolation, Jonathan Wolfe

Honors Theses

The nature of matter and light has been a subject of philosophical debate since antiquity. However, by the end of the nineteenth century, much of the scientific community believed that most of the significant principles that govern the natural world had been discovered. Classical physics was able to explain complex phenomena such as planetary motions, elasticity, and hydrodynamics. The field of thermodynamics had been developed nearly to completion by James Joule, Sadi Carnot, Josiah Gibbs, et al. The magnetic and electronic nature of light had been demonstrated by James Clerk Maxwell's famous equations. In the neighboring field of chemistry, a …

Revenue Diversification In Health And Human Services Nonprofits., Hannah Sayle Flint

Honors Theses

The nonprofit sector is increasingly growing and becoming more important to the United States society and economy. Concurrent with this growth, nonprofits have assumed a larger role in mitigating societal issues and are increasingly being relied upon to provide services that have traditionally been supplied by the government or in some cases not addressed at all. The recent economic recession has highlighted just how vulnerable many of these nonprofit organizations are to fluctuations in the economic cycle. The negative impact the current economic recession has had on the nonprofit sector suggests that the traditional nonprofit revenue model must be reevaluated. …
