120 quality assurance engineers indicated how frequently job stressors, causing distress related to role ambiguity, role conflict, role overload, and career development, affected them at work. They also indicated their satisfaction with their most recent performance appraisal. Satisfaction with performance appraisal was significantly negatively correlated with each stressor.
The effect of race on interrater reliability of peer ratings was investigated using data collected on 1,219 U.S. Army ROTC cadets at summer camp. White raters rating white ratees had a higher interrater reliability than black raters rating black ratees. Implications of this study are discussed.
274 adult volunteers completed a questionnaire concerning how different behaviors and emotions, which may be attributed to alcohol abuse, would affect their performance appraisal ratings of an individual who exhibited those behaviors or emotions. The appearance of behaviors and emotions that might signify alcohol abuse resulted in lower ratings. There was no difference between supervising and non-supervising raters or between male and female raters. Problems in permitting the symptoms to affect performance ratings are discussed.

Fourteen patients with the Wolff-Parkinson-White (WPW) syndrome were studied by means of intracardiac stimulation techniques, before and after the intravenous administration of propranolol, 0.1 mg./Kg. There were no significant change, or only a slight increase, in the effective refractory periods of all parts of the re-entry tachycardia circuit studied, in either anterograde or retrograde directions. Re-entry tachycardia was initiated in nine patients in the control state, and in 10 patients after propranolol. The rate of re-entry atrioventricular node-accessory pathway tachycardia was decreased, but by only 10 per cent. The duration and outer limit of the tachycardia zone of atrial extrastimuli were not significantly decreased. Propranolol, by rapid intravenous infusion administration, is unlikely to be effective primary therapy for PSVT in the WPW syndrome.

The intrinsic heart rate (IHR) was determined in 17 patients with symptomatic sinus bradycardia by administering atropine 0.04 mg/kg and propranolol 0.2 mg/kg, i.v. In this way, sick sinus (SSS) patients with intrinsic sinus node (SN) dysfunction could be distinguished from those patients with disturbed autonomic regulation of SN function. Sick sinus syndrome patients with normal corrected sinus node recovery time (SNRTC), adjusted for the magnitude and direction of autonomic chronotrophy, consistently had normal IHRs and therefore abnormalities of autonomic regulation. Sick sinus syndrome patients with abnormal adjusted SNRTC consistently had abnormal IHRs and therefore abnormalities of intrinsic SN function. We conclude that more than one pathophysiologic mechanism can produce the clinical manifestations of sick sinus syndrome and that abnormal prolongation of SNRTC is dependent upon the underlying mechanism of sinus node dysfunction.
