VIII—Permissible Rescue Killings

Many believe that agent-centred considerations, unlike agent-neutral reasons, cannot show that victims have the right to kill their attackers in self-defence, let alone establish that rescuers have the right to come to their help. In this paper, I argue that the right to kill in self- or other-defence is best supported by a hybrid set of reasons. In particular, agent-centred considerations account for the plausible intuition that victims have a special stake, which other parties lack, in being to thwart the attackers. That special stake plays an important part justifying victims' right to obtain help, and rescuers' right to give it.     

Reply to Wilkinson

In his review of my book Whose Body is It Anyway, Wilkinson criticises the view (which I defend) that confiscating live body parts for the sake of the needy is (under some circumstances) a requirement of justice. Wilkinson makes the following three points: (a) the confiscation thesis is problematic on its own terms; (b) there is a way to justify coercive resource transfers without being committed to it; (c) the thesis rests on a highly questionable approach to the status of the body. Wilkinson’s paper is challenging, and some of his points are well taken. On the whole, however, it does not constitute an insurmountable challenge for my thesis.

Ethics of Immigration: The Issue of Convicted Criminals

In this paper, I explore and probe Joseph Carens’ remarks, in his recent book The Ethics of Immigration, on the immigration status of foreign convicted criminals who have served their sentence, and who wish either to immigrate into our country or who are already here. Carens rejects deportation when it is not called for by considerations of national security, and agrees that considerations of public order can justify barring convicted foreign criminals from entering the country. I broadly agree with his arguments against deportation: my remarks in this respect are clarificatory and exploratory as much as anything else. But (I argue) both his argument for open borders and his scepticism with respect to radical cosmopolitanism are in tension with his claim that past criminal convictions can act as a bar to entry.     

L’examen psychologique dans le handicap visuel : intérêts et limites méthodologiques

The psychological assessment of visually impaired people (blind or partially sighted) confronts the psychologist with methodological constraints regarding the choice of assessment tools. Both critical judgement and an extensive psychometric knowledge are necessary. The objective of this article is to present the results of a study in which the existing tools in this field are identified. The results of this study bring to light the shortage of tools and methods of investigation specifically designed to assess the different psychological facets (affective, cognitive or conative) of visual impairment. We will then examine the methodological and psychometric issues specifically related to assessment in the field of visual impairment. Although some tools have psychometric qualities for the assessment of blind and visually impaired people (Miller & Skillman, 2003; Reid, 1997), we note that the limits of some tests are often overlooked or ignored (Reid, 1997; Tobin, 1994; Tobin & Hill, 2011). Questions relating to the use, adaptation and translation of foreign language tools are examined. In order to illustrate these points, we present some practices used by psychologists which highlight the limits of currently existing tools for the assessment of the psychological, in particular, the cognitive facet, and in addition provide some recommendations for assessment.     

The expression of uncertainty: Two contextual effects

Abstract

Since Foley (1959), the technique of evaluating common expressions of uncertainty on a numerical scale has often been used in an attempt to define such expressions more accurately. Two contextual factors - (1) the composition of the set of expressions and (2) the definition of the scale - were studied in the present experiment to determine their effect on bow such expressions are encoded. Psychophysical theories on series effects and, in particular, the range-frequency model (Parducci, 1983), predict that the composition of a set is one of the determining factors of contrast effects. The scale definition factor determines the lower limit of the rating scale, which represents either uncertainty or negative certainty. The effect of this factor is assumed to depend upon the reference universe outlined in the problem statement and, in particular, upon whether that universe is strictly limited or not. An experiment was conducted to contrast two sets of expressions, two scale definitions and two ways of presenting the problem (the doubt was applied either to a choice of two events or to the occurrence of an event in an unspecified universe). The results provide evidence of a set composition effect and an interaction between the scale definition and the presentation of the problem. This is consistent with the proposed model, which accounts for the specific effects of the judgement task while eliminating the need to consider the variability of the meanings themselves. Proposals for developing this line of research are presented in the discussion.
