Drug testing,drug treatment,and marijuana use: a fairness perspective

The authors conducted a random statewide telephone survey of 1,484 individuals to study the relationship between marijuana use (in terms of participants' history of marijuana use) and reactions to drug testing and to study 2 hypothetical drug-treatment policies. Job safety sensitivity was related to perceived fairness of drug testing for the participant's job, and more recent marijuana use was associated with more negative reactions. Safety sensitivity was related to perceived fairness of drug treatment. Organizations with voluntary treatment were more attractive than ones with monitored treatment. Marijuana use interacted with drug treatment policy type in predicting reactions to drug treatment. Results suggest that organizations should consider job and employee characteristics when developing a drug treatment policy.     

Type a behavior pattern in mothers of infants: An exploration of associations with attachment,sensitive caregiving,and life-events

Abstract

In the present study. 83 lower- to upper-middle class mothers of first-born, 12-month-old infants were interviewed with the Adult Attachment Interview (George, Kaplan, and Main, 1985), and completed the Groninger Intelligence Test (Luteijn and Van der Ploeg, 1982). Eighteen months after the beginning of the study, 67 mothers (81% of the original sample) were interviewed with the Structured Interview (Rosenman, 1978), and were observed during a brief, semi-structured play session at home with their child - at that time a 2.5-years-old toddler. They also completed a checklist about major life-events that had occurred during the past 18 months. A large majority of these mothers of young children (81%) showed Type A behavior patterns. The job of parenting, indeed, appears to be stressful. Attachment and Type A behaviors, however, did not seem to be related, probably because the influence of attachment is restricted to the regulation of emotions in intimate relationships. Yet, Type A behavior predicted a more sensitive parenting style than Type B did. All mothers who experienced negative life-events or Serious health problems in the recent past showed Type A behavior patterns. Our findings show that the Structured Interview can be applied in a valid manner to mothers of young children passing trough a demanding phase in their lives. Further research is needed to uncover the causes of the high prevalence of Type A behaviors in young mothers.     

Rationality in Action: A Symposium

Abstract

John Searle's forthcoming book ‘Rationality in Action’ presents a sophisticated and innovative account of the rationality of action. In the book Searle argues against what he calls the classical model of rationality. In the debate that follows Barry Smith challenges some implications of Searle's account. In particular, Smith suggests that Searle's distinction between observer-relative and observer–independent facts of the world is ill suited to accommodate moral concepts. Leo Zaibert takes on Searle's notion of the gap. The gap exists between the reasons that we have for acting and our actions. According to Searle, whenever there is no gap, our actions exhibit irrationality. Zaibert points out a certain obscurity in Searle's treatment of the gap, particularly in connection with Searle's notion of ‘recognitional rationality’. Finally, Josef Moural examines the interactions between Searle's theory of institutions and his theory of rationality, with emphasis on the connections between intentionality and Searle's notion of the ‘background’.     

On Two Versions of ‘the Surprise Examination Paradox’

In this paper, I consider a popular version of the clever student’s reasoning in the surprise examination case, and demonstrate that a valid argument can be constructed. The valid argument is a reductio ad absurdum with the proposition that the student knows on the morning of the first day that the teacher’s announcement is fulfilled as its reductio. But it would not give rise to any paradox. In the process, I criticize Saul Kripke’s solution and Timothy Williamson’s attack on a key step of the student’s reasoning. I then consider the condemned prisoner case in W. V. Quine’s paper ‘On a So-Called Paradox’. I argue that the prisoner’s reasoning as conceived by Quine is more relevant and reasonable than the student’s argument in the popular version of the surprise examination case. I also argue that Quine’s criticism of the prisoner’s reasoning is correct, and therefore that the condemned prisoner case, and the surprise examination case as well, would not generate any paradox.     

Hyperthermia impairs retrieval of an overtrained spatial task in the Morris water maze

Fifteen rats were trained to learn the location of a spatially fixed platform hidden in a Morris water maze (40 +/- 2 degrees C). Then retention of the spatial task was assessed immediately after raising core body temperature (Tc) to 42 or 40 degrees C or stabilizing at 37 degrees C (the normothermic control). The hyperthermic treatment order was counterbalanced according to a Latin-square design. Hyperthermia at 42 degrees C Tc significantly impaired spatial performance. Hyperthermic animals were cooled to normothermia (Tc = 37 degrees C) and spatial performance was tested again approximately 30 min later. Cooling resulted in a complete recovery of spatial performance. These results demonstrate that hyperthermia-induced amnesia can be obtained on an overtrained spatial-mapping strategy and cooling to normothermia initiates recovery of spatial performance.
