Concerns of Older Veteran Callers to the Veterans Crisis Line

When the Veterans Crisis Line (VCL) was implemented, it was uncertain if veterans, and particularly older male veterans, would utilize the service. We examined VCL use by a growing group of veterans at increased risk for suicide: those aged 60 and older. Real‐time clinical data were gathered from a weekly random sampling of calls. Approximately 25% of calls were from veterans aged 60 or older; over 80% reported benefit from the call. Several significant differences in presenting concerns between older and younger callers were found. Targeted outreach to encourage older veterans to use the VCL is suggested.     

Genetically Based Handicap

It is unclear what we should make of a policy designed to 'eradicate' genetically based handicap, and in particular whether it constitutes discrimination against people with a genetic handicap. After brief reference to the legal position, four arguments are examined which purport to justify differential treatment of handicapped lives either before conception or before birth: the argument from genetic 'error', the argument from parental responsibility, the argument from social consequences and the argument from impersonal harm. Weaknesses are detected in each of these arguments, and the conclusion is drawn that, although differential treatment of handicapped lives is sometimes justified, there are some circumstances in which it does amount to discrimination.     

Does the theory of planned behavior mediate the effects of an oncologist's recommendation to exercise in newly diagnosed breast cancer survivors? Results from a randomized controlled trial.

This randomized trial examined the effects of 2 oncologist-based exercise interventions--recommendation only (RO) and recommendation plus referral (RR)--versus usual care (UC) on social-cognitive constructs from the theory of planned behavior (TPB). The authors also examined whether the TPB mediated the significant effect of the RO intervention on exercise and explained the null effect of the RR intervention. Independent t tests revealed that both interventions had significant effects on TPB constructs; however, only the RO intervention impacted perceived behavioral control (PBC). Path analyses indicated that PBC was the only construct with a direct effect on exercise and that it mediated the effect of the RO intervention on exercise and explained the null effect of the RR intervention.     

Overshadowing and Blocking as Acquisition Deficits: No Recovery After Extinction of Overshadowing or Blocking Cues

The effects of extinction of the blocking or overshadowing stimulus on conditioned responding controlled by the blocked or overshadowed stimulus were examined in seven appetitive conditioning experiments with rats. The experiments differed in their designs, stimuli used, the amounts of conditioning and extinction training, and the levels of conditioned responding produced. In all cases, conditioned responding to the blocked or overshadowed cue was either unaffected or reduced by extinction of the blocking or overshadowing cue. These data are consistent with accounts of overshadowing and blocking that attribute those phenomena to acquisition deficits, rather than to retrieval failures.
