Taking Shots at Private Military Firms: International Law Misses its Mark (Again)

Part I of this Article takes a brief tour through military history on the consistent use of mercenaries through the ages, which Peter Singer illuminates masterfully in Corporate Warriors. Next, a brief overview on the binding nature (or not) of international custom and treaty is explored in Part II and then the codifications of international law are taken up in Part III, beginning with the Hague and Geneva Conventions. Several United Nations (“U.N.”) instruments are analyzed for their efficacy in changing the long-standing customary international law on the use of mercenaries and whether or not each is applicable to PMF contractors. Part IV closes out the Article by discussing alternative bodies of domestic law that provide criminal accountability, including the recent case of Alaa Mohammad Ali, a civilian contractor working in Iraq who was convicted on June 23, 2008 by court martial under the recent changes to the Uniform Code of Military Justice (“UCMJ”)

Testing a Mahalanobis Distance Model of Black Bear Habitat Use in the Ouachita Mountains of Oklahoma

Regional wildlife–habitat models are commonly developed but rarely tested with truly independent data. We tested a published habitat model for black bears (Ursus americanus) with new data collected in a different site in the same ecological region (i.e., Ouachita Mountains of Arkansas and Oklahoma, USA). We used a Mahalanobis distance model developed from relocations of black bears in Arkansas to produce a map layer of Mahalanobis distances on a study area in neighboring Oklahoma. We tested this modeled map layer with relocations of black bears on the Oklahoma area. The distributions of relocations of female black bears were consistent with model predictions. We conclude that this modeling approach can be used to predict regional suitability for a species of interest

Climatic implications of background acidity and other chemistry derived from electrical studies of the Greenland Ice Core Project ice core

High-resolution continuous profiles were obtained on the Greenland Ice Core Project (GRIP) ice core using two different electrical methods. After correction for temperature and density, the electrical conductivity method (ECM) technique responds only to acidity, while dielectric profiling (DEP) responds to acid, ammonium, and chloride. Detailed chemistry on a section of glacial-age ice allows us to confirm the calibration factor for chloride in DEP. Acidity dominates the DEP variability in the Holocene, Allerod/Bolling, and larger interstadials; ammonium dominates in the Younger Dry as, while chloride is the major contributor in cold periods including smaller interstadials. From the electrical signals plotted on a linear timescale we can deduce the background (nonvolcanic) acidity of the ice, varying from always acidic in the Holocene to always alkaline in the cold periods. In the interstadials, the ice is close to neutral, with most of it acidic in larger interstadials, most of it alkaline in smaller ones, and rapid alternations within interstadials. It is not clear whether neutralization of individual acidic particles occurred in the atmosphere or whether acid and alkaline particles coexisted until deposition in the snowpack. The changes in acidity observed at GRIP apply at least to all of Greenland and probably to much of North America. There would have been ecological effects and important changes in the uptake of some chemicals onto ice. If acidic sulfate particles were neutralized and removed from the atmosphere, which remains uncertain, then there are atmospheric chemistry and radiative effects that require further investigation
