AbstractWe propose that humans are prepared to interpret giving as a diagnostic cue of reciprocal–exchange relations from infancy. A prediction following from this hypothesis is that infants will represent the identity of an object they see being given, because this information is critical for evaluating potential future reciprocation. Across three looking-time experiments we tested whether the observation of a transfer action induces 12-month-olds to encode the identity of a single object handled by an agent. We found that infants encoded the object identity when the agent gave the object (Experiment 1), but not when she took it (Experiment 2), despite being able to represent the goal of both actions (Experiments 1 and 3). Consistent with our hypothesis, these results suggest that the infants’ representation of giving comprises information necessary for comparing the value of transferred goods across sharing episodes.

Studies of lightness constancy typically involve the comparison of two objects of the same shade that have been placed under different illuminations. In this study, we introduce factors such as object identity and immediate prior experience to measure the effect of these manipulations on constancy. In the first experiment, conditions sufficient to reproduce classical constancy failure (illumination difference, target values, articulation level) were determined. In the second experiment a lightness judgment was made for a gray target that was then seen to move into another illumination level for the second match. Motion was used in an attempt to stress the target?s identity. The shade was still judged significantly lighter when placed under the higher than under the lower illumination. Failure of constancy thus occurred even when object identity was not in question. In the third experiment a priming paradigm was used, to assess the strength of constancy: one shade would appear in one illumination level and another shade in the other illumination level. Motion was used to trick observers into thinking that only a single object was presented. The estimated shade varied as a function of the shade of the prime. In the last experiment, observers were asked to make another match when the object was removed from view: the match of its true color independent of illumination. The value of this match-from-memory was based on the value obtained in the higher illumination level. Taken together, the experiments show that through object identity, immediate prior experience can influence lightness in systematic fashion.

AbstractThis article analyses the conversion process and the experiences of the Sidāma, in being proselytised by Protestant missionaries in an attempt to integrate them into the modernising Ethiopian state. The conversion process is considered in terms of reasons for accepting or rejecting the new religion. A minority of Sidāma are shown to have changed from old beliefs and practices, partly because of the ease of moral reinterpretation and secular incentives, but primarily because of dissatisfaction with reciprocal exchange relations with indigenous spirits and a desire to transcend the finality of death. In advancing this proposition it rejects the possibility of Sidāma beliefs as constituting a closed system of cosmology. Though Islam is also present in the region, for political and economic reasons it has been less attractive to prospective converts than Christianity.

Property is what’s exchanged in markets, and this chapter examines its nature, introduces the ideological dispute between Locke and Bentham over its origins and the implications of their views for government and individuals, and shows how and to what effect property is exchanged in explicit markets. Rights are distinguished from objects, and property is defined as rights to control specific objects for specific uses at specific times, so different people may own different property rights in a single object at the same time. For Locke, individuals have these rights naturally and create government to protect them, while Bentham argues that government creates rights and can allocate them coercively toward its proper ends. The creation of new rights to resolve disputes is considered, and movement of property rights to higher-valuing owners by voluntary exchange in perfectly favorable conditions is illustrated by a hypothetical dispute over the use of a house.

The Relationship

This chapter concerns the relationship between the split-brain case and the non-split case. In the first half of the chapter, I consider arguments to the effect that if split-brain subjects have two minds apiece, then so do non-split subjects. Sometimes these arguments have taken the form of a reductio against the 2-thinkers claim for split-brain subjects. These arguments do not work: that a split-brain subject has two minds does not mean that I have two minds, although it does mean that I could. The second half of the chapter offers my own proposal for the respect in which R’s and L’s co-embodiment as one animal, S, makes a split-brain subject one of us: I argue that S must be the single object of both R’s and L’s implicit bodily self-awareness.

Basal Sliding

AbstractThe results of regelation experiments, in which a single object is pulled through ice, cannot be applied directly to the problem of basal sliding in glaciers because the two systems have different geometries. When the force applied to a single object is small, impurities trapped in the regelation water-layer around the object inhibit the regelation process. At larger forces, above the Drake-Shreve transition point, impurities are shed in a trace behind the object. However, when ice moves over a series of obstacles a trace may exist above and below the transition point. The regelation velocity below the transition point is not reduced by the effect of trapped impurities. In an experiment in which brass cylingerrs of various cross-sections rotate in ice, the ratio between the expected regelation velocity, calculated using the basal-sliding theory of Nye, and the measured regelation velocity is 8±2, both above and below the transition point. The same ratio has been obtained by other workers with wires of similar thermal conductivity above the transition point. Measurements of température differences indicate that supercooling cannot be the main source of the unexpectedly low regelation velocities above the transition point.

Exchange Relations

AbstractGlobal value chains (GVCs) resist dominant contract framing, because presumptions about contract’s bilateral structure and party autonomy fail to capture the complex interconnections between private exchange relations. Contract law seems to obscure, rather than capture, the ways in which the relationships and experiences of various actors in GVCs are linked. This article argues that, in doing so, contract law contributes to systemic hermeneutical injustice. Systemic hermeneutical injustice captures how shared interpretative resources can render those in disadvantaged positions of social power unable to make intelligible that what is in their interest to render intelligible. The article’s primary aim is to show how this form of injustice bears on contract law and how it can function as an independent normative constraint on the institution of contract law.
