Democratic Moral Education and the Gifts of the Holy Spirit

How far is Thomas Aquinas available for current discussions in political philosophy? While there are certainly things to be learned from him about our political preoccupations, the pedagogy of his moral teaching typically resists our familiar questions. This holds even when the question is put in terms that Thomas should recognize—say, as a question about the virtues appropriate for a democracy. Thomas not only gives different meanings to these terms, he moves political topics away from the center of theological attention and so organizes them very differently. A reader can notice these differences at many points but perhaps especially in the attention that Thomas gives in the Summa to the gifts of the Holy Spirit. His account of these gifts qualifies significantly what he says of virtue and suggests large limits on human agency, whether in ethics or in politics.     

Object-based inhibition of return in static displays

After attention has been oriented to a location, inhibition mechanisms prevent the return of attention shortly afterward. This inhibition can be associated with an object in such a way that after cuing attention to the object, inhibition can move with the object to a new location. Recent research has noted that the object-based inhibition of return effect in moving displays is much smaller than the effect observed in static displays, and hence may be of little functional utility. However, we demonstrate that, on the contrary, the large effects observed in static displays are produced precisely because of the existence of object-based frames, which can be additive with location-based frames of reference.     

Classical conditioning of the nictitating membrane response of the lemon shark (Negaprion brevirostris)

An experimental group of lemon sharks received 100 daily presentations of light flash as the conditioned stimulus (CS) and electric shock as the unconditioned stimulus (US) in a classical conditioning situation. The conditioned responses (CRs) and unconditioned responses (URs) under observation consisted of extensions of the nictitating membrane. Separate control groups received either (a) no CS or US, (b) CS-alone, or (c) completely random presentations of CS and US. Few CRs occurred in the experimental group at the outset of conditioning, but the percentage of CRs during the second half of the first acquisition session exceeded 95%. Conditioning stabilized above 95% CRs during Acquisition Sessions 3 through 7. These responses could not be attributed to pseudoconditioning, sensitization, or other nonassociative factors. When the experimental group was subsequently given six CS-alone sessions, the course of extinction was gradual. Most results seemed similar to those previously obtained during classical conditioning of the nictitating membrane in rabbits.

Conflict Minerals in Electronic Systems: An Overview and Critique of Legal Initiatives

The Democratic Republic of Congo has vast natural resources, many of which are regularly exploited by the electronics industry. Unfortunately, in addition to these resources, there are widespread human rights abuses committed by armed groups entrenched in the eastern part of the Democratic Republic of Congo. These armed groups are using profits from these minerals as a source of funding. Their human rights abuses have led to a growing humanitarian interest in the region and prompted the international community to action. This paper explores the conflicts in the Democratic Republic of Congo, provides an understanding of the link between human rights abuses and conflict minerals, and interprets and critiques the legal actions of the international community.
