Schwinger-Dyson equations and disorder

Using simple models in D=0+0 and D=0+1 dimensions we construct partition functions and compute two-point correlations. The exact result is compared with saddle-point approximation and solutions of Schwinger-Dyson equations. When integrals are dominated by more than one saddle-point we find Schwinger-Dyson equations do not reproduce the correct results unless the action is first transformed into dual variables.Comment: 7 pages, 6 figure

The Execution of the Innocent

Radelet and Bedau discuss the continuing and regular incidence of American trial courts sentencing innocent defendants to death, which was one of the problems that gave rise to the ABA\u27s moratorium on capital punishment

The Precarious Sovereignty of Rights

This paper argues that the typical theory of human rights is both defective and misleading. It is misleading insofar as the rights that these theories generate are not the powerful moral swords and shields that their advocates take them to be. It is defective insofar as it fails to confront the chief sources of trouble for theories of rights. In sum, rights do not have the finality in human affairs that is often claimed for them

The philosophical doctrines in Tertullian's De Anima.

Thesis (M.A.)--Boston UniversityThis thesis is an attempt to examine the treatise De Anima written by Quintus Septimius Florens Tertullianus circa A. D. 210. Special attention is paid to the sources for his doctrines, both Christian and non-Christian, as well as the influences this treatise had on later medieval thought. The systematic presentation of Tertullian's views is not construed to mean that Tertullian produced a really systematic philosophy in De Anima. One thread runs continuously through the thesis, namely, the problem of faith and intellect, revelation and reason, which occurs in every context and influences the actual philosophical positions adopted by Tertullian.

A Retributive Theory of the Pardoning Power?

During the past two decades; the retributive theory of punishment has made remarkable strides in recapturing the affections of penologists. The story has been told elsewhere and need not be reviewed here. For philosophers, if not for others interested in the theory and practice of punishment, a retributive approach holds a double attraction

The Cost of Coexistence between Bt Maize and Open Pollinated Maize Varieties in Lowland Coastal Kenya

Kenya is currently in the process of introducing genetically modified maize (Bt maize). A major concern is that the Bt gene might cross into local varieties through cross pollination. Current regulatory strategies to ensure coexistence of the two cropping systems at the farm level rely on spatial isolation measures-separation distances and/or buffer zones. However, the interaction of practical measures and costs of spatial isolation with the farmer’s economic incentive to plant a Bt maize crop have not been studied in Kenya. The purpose of this study was to analyze the technical and economic feasibility of the implementation of spatial coexistence measures. Using spatial geo-referenced data from the actual agricultural landscape in lowland coastal Kenya, the study finds that flexible separation distances hold the possibility of ensuring coexistence in the region, but will be difficult to implement. Rigid buffer strips on the other hand are not consistent with the producers’ economic incentive to plant a Bt maize crop.Coexistence, Regulatory, Spatial, Agro-ecological zone, GM crops, Resource /Energy Economics and Policy,
