Murdoch's ontological argument

Anselm's ontological argument is an argument for the existence of God. This paper presents Iris Murdoch's ontological argument for the existence of the Good. It discusses her interpretation of Anselm's argument, her own distinctive appropriation of it, as well as some of the merits of her version of the argument. In doing so, it also shows how the argument integrates some key Murdochian ideas: morality's wide scope, the basicness of vision to morality, moral realism, and Platonism.     

Differences between Saimiri sciureus and Callicebus moloch in physiological responsiveness: implications for behavior

The New World primates Callicebus moloch and Saimiri sciureus differ markedly in life modes. Physiological responsiveness (heart rate, cortisol) of these related taxa was compared in two situations that differed in the presumed degree of stress imposed, exposure to a novel environment and physical restraint. In both situations, Saimiri exhibited higher initial levels of heart rate and corticosteroids. In addition, the species differed in their patterns of response to both situations. Saimiri maintained initial heart rate levels across a 1-hour exposure period, whereas Callicebus showed a marked and continuous decline in heart rate. Adrenocortical activity increased in both species in response to test situations, but the elevations in plasma corticosteroids were substantially greater for Saimiri than for Callicebus. The results indicate that the species differ with respect to organization of physiological regulatory systems in a manner consistent with behavioral contrasts between them.     

A PRACTICAL STRATEGY FOR ONGOING REINFORCER ASSESSMENT

There is a need for practical methods of reinforcer assessment that systematically track ongoing changes in clients' preferences. In this study, the effects of a time-efficient reinforcer assessment package were evaluated in a multiple baseline across 3 preschoolers with autism, comparing individualized item selections by experienced teachers with children's presession preferences for items of various sensory qualities. Systematic assessment of children's reinforcers for correct responding virtually eliminated nontargeted maladaptive behaviors, as well as yielding expected improvements in accuracy. The powerful side-effects of potent reinforcers underline the importance of increased attention to reinforcer assessment in research and practice.     

ARTIFACTUAL EFFECTS OF SENSORY-INTEGRATIVE THERAPY ON SELF-INJURIOUS BEHAVIOR

Three individuals who exhibited self-injurious behavior (SIB) were exposed to sensory-integrative therapy. Prior to treatment, a functional analysis baseline was conducted to identify the motivational features of their SIB. One subject's SIB appeared to be an attention-getting response (maintained by positive reinforcement), which varied subsequently as a function of attention being either withheld or provided noncontingently during sensory-integration sessions. The 2nd subject displayed a pattern of responding suggestive of stereotypic SIB (maintained by automatic reinforcement), which paradoxically increased during sensory-integration sessions. The 3rd subject's SIB appeared to function as an escape response (maintained by negative reinforcement), and his behavior during sensory-integration sessions was similar to that observed during baseline sessions in which demands were not present. The SIB of all 3 subjects later was reduced when behavioral interventions were applied. The data presented raise questions about the active components of sensory-integrative therapy and the functional types of SIB for which it might be appropriate.     

Preference paradigm: provides better self-stimulation reward discrimination than a rate-dependent paradigm

To obtain a better understanding of how well the Y-maze preference test paradigm indexes electrical brain stimulation reward, the present experiment compared the abilities of this rate-independent paradigm and a rate-dependent paradigm to assess the rewarding effectiveness of brain stimulation. The rate-dependent paradigm used was an operant chamber. The results showed that over a wide range of stimulation parameters the rate-independent paradigm provided a better assessment of the rewarding effectiveness of the brain stimulation than did the rate-dependent paradigm.     

Fallout from government-sponsored radiation research.

On December 28, 1993, Energy Secretary Hazel R. O'Leary publicly appealed to both the executive and legislative branches of the United States Government to consider compensation for individuals who were harmed by their exposure to ionizing radiation while enrolled in government-sponsored studies conducted between 1940 and the early 1970s. The call for compensation was issued three weeks after Secretary O'Leary disclosed that radiation experiments involving humans, sometimes without their consent, had occurred under the auspices of the Atomic Energy Commission (AEC), a forerunner of the Department of Energy (DOE). Secretary O'Leary directed her department to investigate the nature and extent of the experiments, report on their medical and ethical acceptability, and locate the research subjects or their families.     

Applying public health science to the counselling profession: An initial examination

The application of public health science to the counselling profession is examined. Specifically, the public-health practices of prevention and epidemiology are reviewed for their applicability to the field of counselling. Evidence of the counselling profession's substantial involvement in the prevention research field is provided through an examination of recent major meta-analysis articles on prevention studies. The role of the counselling profession in social-policy development, and the interrelation between this type of social/political engagement and the solidification of the counselling field within the spectrum of mental-health services, are explored.     

Do Consequentialists Have One Thought Too Many?

In this paper I defend consequentialism against the objection that consequentialists are alienated from their personal relationships through having inappropriate motivational states. This objection is one interpretation of Williams' claim that consequentialists will have "one thought too many". Consequentialists should cultivate dispositions to act from their concern for others. I argue that having such a disposition is consistent with a belief in consequentialism and constitutes an appropriate attitude to personal relationships. If the consequentialist has stable beliefs that friendship is justifiable in consequentialist terms, that friendship requires acting from concern for others, and furthermore if the consequentialist finds that she is concerned for others, then she will be able to form a disposition which involves acting from her concern for others without having one thought too many.
