Don’t Ever Do That! Long-term Duties in <Emphasis Type="Italic">PD</Emphasis><Subscript><Emphasis Type="Italic">e</Emphasis></Subscript><Emphasis Type="Italic">L</Emphasis>

This paper studies long-term norms concerning actions. In Meyer’s Propositional Deontic Logic (PD _e L), only immediate duties can be expressed, however, often one has duties of longer durations such as: “Never do that”, or “Do this someday”. In this paper, we will investigate how to amend PD _e L so that such long-term duties can be expressed. This leads to the interesting and suprising consequence that the long-term prohibition and obligation are not interdefinable in our semantics, while there is a duality between these two notions. As a consequence, we have provided a new analysis of the long-term obligation by introducing a new atomic proposition I (indebtedness) to represent the condition that an agent has some unfulfilled obligation.

An adventure in scholarship and faith: Reflections on the study centre 1975–1992

CSIC has now had 15 years' experience of Muslim/Christian partnership in an adventure of faith and scholarship. How honest have the partners been able to be with each other, and with the rest of the world? CSIC was a Christian initiative, yet quickly became a co‐operative venture. One of its emergent problems was how to present Christianity intelligibly to Muslims; another the perennial issue of dialogue and mission. Faith and reason clashed predictably among the students, but many outside the institution valued its expertise in their professional responsibilities, and CSIC acquired the credibility to contribute to wide‐ranging socio‐political debates. May the adventure continue, at the expense of academic safety, if necessary.     

Spatial frequency and attention: Effects of level-, target-, and location-repetition on the processing of global and local forms

Is attentional selection between local and global forms based on spatial frequency? This question was examined by having subjects identify local or global forms of stimuli that had been “contrast balanced,” a technique that eliminates low spatial frequencies. Response times (RTs) to global (but not local) forms were slowed for contrast-balanced stimuli, suggesting that low spatial frequencies mediate the global RT advantage typically reported. In contrast, the beneficial effect of having targets appear at the same, as opposed to a different, level as that on the immediately preceding trial was unaffected by contrast balancing. This suggests that attentional selection between different levels of structure is not based on spatial frequency. The data favor an explanation in terms of “priming,” rather than in terms of adjustments in the diameter of an attentional “spotlight.”     

Autonomy and the refusal of life-prolonging therapy

Conclusion Autonomous decision-making over therapy options is not reducible to the refusal of unwanted medical intervention. This is a myth that has been imported from questionable assumptions in political economy, and is of little benefit to medical practice and the sometimes agonizing decisions which have to be taken by patients and their relatives. An individual's right to therapy abatement can be protected from abuse only in the context of a full understanding of autonomous choice; not merely the right to refuse, but the opportunity to receive assistance and consider alternatives. Limits are also required on the role of the surrogate in the refusal of therapy. Policies endorsing therapy abatement and exercise of the right to forego life-sustaining therapy should carry cast iron guarantees that they will not be disadvantageous to the poor and undereducated members of society. It should also be noted that fears of unlimited life-prolongation have been greatly exaggerated. In an atmosphere of governmental indifference to the plight of the sick, with the notion of welfare tuned to market forces, there is a danger that self-determination can have a restricted meaning; the option of death in the context of an underfunded health service. This may not be the time to campaign for the right to refuse therapy, but rather the time to campaign for improvements to existing therapy.     

An application of Strong's validity criteria to basic interest scales

E. K. Strong, Jr.'s (Vocational interests of men and women, Stanford, Calif.: Stanford Univ. Press, 1943) four propositions for interest-inventory validity andJ. L. Holland's (Making vocational choices: A theory of careers, Englewood Cliffs, N.J.: Prentice-Hall, 1973) hexagonal classification system were synthesized in order to adapt a traditional procedure for determining the construct validity of occupational interest scales to the validation of basic interest scales. The procedure was tested using a sample of 4035 males and 3671 females whose interest inventory results as high school students and whose majors as college seniors could be assigned Holland codes. Results of the study indicate that this procedure can be used to assess the construct validity of inventories using basic interest scales.
