Nash equilibria of network formation games under consent

We investigate the Nash equilibria of game theoretic models of network formation based on explicit consent in link formation. These so-called “consent models” explicitly take account of link formation costs. We provide characterizations of Nash equilibria of such consent models under both one-sided and two-sided costs of link formation. We relate these equilibrium concepts to link-based stability concepts, in particular strong link deletion proofness.

Informed Consent: Autonomy and Self-Ownership

Using the example of an unconsented mouth swab I criticise the view that an action of this kind taken in itself is wrongful in respect of its being a violation of autonomy. This is so much inasmuch as autonomy merits respect only with regard to ‘critical life choices’. I consider the view that such an action is nevertheless harmful or risks serious harm. I also respond to two possible suggestions: that the action is of a kind that violates autonomy; and, that the class of such actions violates autonomy. I suggest that the action is wrongful in as much as it is a bodily trespass. I consider, and criticise, two ways of understanding how morally I stand to my own body: as owner and as sovereign. In respect of the latter I consider Arthur Ripstein’s recent defence of a sovereignty principle. Finally I criticise an attempt by Joel Feinberg to explain bodily trespass in terms of personal autonomy.

Informed consent and the requirement to ensure understanding

It is generally held that doctors and researchers have an obligation to obtain informed consent. Over time there has been a move in relation to this obligation from a requirement to disclose information to a requirement to ensure that that information is understood.Whilst this change has been resisted, in this article I argue that both sides on this matter are mistaken.When investigating what information is needed for consent to be informed we might be trying to determine what information a person would need in order to consent at all, or we might be trying to determine what information a person needs in order to make an informed choice about whether or not to consent. I argue that the obligation to ensure understanding only applies to information generated by the ?rst type of enquiry; but that much of the information generally thought necessary in order for consent to be informed is only required if our concern is with the second type of enquiry. For this reason it is neither the case that doctors and researchers should ensure all the information they provide is understood, nor is it the case that their only obligation is to disclose it.

Doonloughan: a seasonal settlement site on the Connemara coast

A series of shell middens and miscellaneous habitation sites, located in a dune
system in west County Galway, have been exposed and are slowly disappearing
through wind, wave and surface erosion. In 1992 a project was initiated to
record, sample and date some of these sites and the radiocarbon results
demonstrated that activity in the area spanned the Early Bronze Age through to
the Iron Age and into the early and post medieval periods. This preliminary
fieldwork was succeeded by the excavation of three of the better-preserved sites; a Bronze Age midden in 1994 and two early medieval sites (the subject of this paper), in 1997. The medieval sites dated to the late-seventh to ninth century adand were represented by a sub-circular stone hut with a hearth and the charred remains of a more ephemeral wooden tent-like structure. The discovery of a bronze penannular brooch of ninth/tenth century date at the latter site wouldsuggest that the settlements are not the remains of transient, impoverishedpeoples of the lower classes of society, eking out a living along the coast. The calcareous sands ensured good preservation of organic remains*fish and mammal bones, charred cereal grains, seeds and seaweed, and marine molluscs. Analyses of these indicated exploitation of marine resources but, otherwise, were comparable with the diet and economy represented by assemblages from established contemporary site types of the period. Unlike raths, cranno´gs and monastic settlements, however, the volume of material represented at the Galway sites was slight, despite the excellent preservation conditions. A range of seasonal indicators also suggested temporary habitation: probable latespring/summer occupation of the stone hut site and autumnal occupancy of the second, less substantial site. It is suggested that the machair plain, beside which the dunes are located, was most probably the attraction for settlers to the area and was exploited as an alternative pasture for the seasonal grazing of livestock.
