The local isometric endurance of the elbow flexors of four groups of five female subjects was tested. Two groups had the circulation to the contracting muscles occluded by a pressure cuff and the others had normal circulations. One group in each of the open and occluded conditions worked with a load equivalent to one-third of maximum strength and the other group worked against a resistance of two-thirds of maximum strength. The endurances of the two groups working with two-thirds of maximum strength as load were not significantly different despite the occlusion of the blood supply in one of the groups. The endurance of the group with open circulation and one-third of maximum strength as load was significantly greater than that of the group with the same load but with occluded blood supply. Only at this lower level of loading did the artificial occlusion of the blood supply to the active muscle group appear to reduce its endurance. Submitted on October 19, 1962

The isometric endurance of the palmar flexors was measured in 11 subjects who had the blood supply to the forearm occluded by means of a pressure cuff on the upper arm. The endurance load was determined as a percentage of the maximum strength of each muscle group and, in this study, varied from 35 to 85%. Load was graphed against endurance and equations were established for the relation which, under the conditions of high loading in the experiment, appeared to be linear. contraction metabolism; strength as a predictor of endurance; contraction producing intramuscular vascular occlusion Submitted on December 30, 1963

Two studies of the Revised NEO‐Personality Inventory (NEO‐PI‐R) conducted on two different applicant samples (one consisting of 539 female subjects and the other consisting of 396 male subjects) are reported. Factor analysis of the female sample yielded a five‐factor solution, highly congruent with the factors presented by Costa, McCrae and Dye (1991). Results of the male data were less clear‐cut, yielding four to five factors which were moderately congruent with the American data. The combined male and female sample showed again high congruence coefficients. Various minor deviations in the location of the facet variables are discussed.

The relative contribution of sex and situation has become a contested issue in the understanding of sex differences in behavior. In the present study, 20 male and 20 female undergraduates were asked to describe their behavior and thoughts in six everyday college situations. Three of the situations were constructed to be typically male and three typically female in content. The results indicate that men and women demonstrate sex-specific characteristics in their responses regardless of the type of situation presented. Men exhibited concern with separateness from others, while women exhibited concern with sustaining connection to others, even when faced with situations described to present demand properties that might be expected specifically to elicit the concern characteristic of the other sex. However, for these students the situation also made a difference: female-defined situations elicited the most masculine responses for both male and female subjects.

I have read with interest Doctors Adams' and El-Salawy's comments on my case report identified in their letter as the "Lausanne baby." I do think that the "Lausanne baby" represents a case of pulmonary vascular sequestration inasmuch as the inferior lobe of the left lung received its blood supply by means of three arterial branches coming off directly from the aorta. On the other hand, I do not think that the "Lausanne baby" is a case of pulmonary parenchymal sequestration and this because the inferior lobe of the left lung was proven to be, at least to my satisfaction, in direct communication with the remainder of the respiratory tract.

Objectives: The purpose of this study was to investigate the effects of backrest angle and hand maneuver direction on maximum hand strength and to recommend a strength value for the hand-controlled stick of an aircraft. Methods: Forty-eight female subjects were recruited to perform simulated forward–backward and adduction–abduction maneuvers using control sticks. Each subject was free from musculoskeletal disorders and pain. The independent variables included four control maneuvers (forward, backward, adduction, abduction), two right-hand control stick locations (central, side), and three backrest angles (90°, 103°, 108°). The dependent variable was maximum hand strength. Results: The maximum strength for forward maneuvers with both central and side sticks was strongest at a 90° backrest angle (p < 0.001). The maximum strength for adduction maneuvers with both central and side sticks was also strongest at a 90° backrest angle (p < 0.001). On the other hand, the highest strength was observed at a 108° backrest angle when pulling the stick backward (p < 0.001). The abduction strength was significantly stronger than the adduction strength with a central stick (p < 0.001), but the adduction strength was significantly stronger than the abduction strength with a side stick (p < 0.001–p = 0.017). The forward and abduction strength were significantly different in different locations (p < 0.001). The recommended strength in the Code of Federal Regulations (CFR) by the US FAA is higher than the strength values observed in this study. Conclusions: The backrest angle, directions, and location affected the muscular strength. The recommended values should be reevaluated and adjusted for Taiwanese pilots.

It is increasingly realized that hypnosis may be seen from an interpersonal point of view, meaning that it forms part of the relationship between the hypnotist and the subject. From this premise it follows that what goes on in the relationship prior to hypnosis probably has an influence on the hypnosis. Certain of these prior occurences can then be seen as waking suggestionns (however implicitly given) that the subject should behave in a certain way with regard to the subsequent hypnosis. A study was conducted to test the hypothesis that waking suggestions regarding post-hypnotic amnesia are effective. Eighteen female subjects were randomly divided into two groups. The groups listened to a tape-recorded talk on hypnosis in which for the one group amnesia for the subsequent hypnotic experience and for the other group no such amnesia was suggested. Thereafter the Stanford Hypnotic Susceptibility Scale was administered to all subjects. Only the interrogation part of the amnesia item of the scale was administered. The subjects to whom post-hypnotic amnesia was suggested tended to score lower on the amnesia item than the other subjects, as was expected, but the difference between the mean amnesia scores of the two groups was not significant.

Arterial Anatomy

The extraosseous and intraosseous vascularity of the talus was studied in 26 fresh cadaver limbs. The specimens were injected with latex or Batson's compound, debrided by a nondissection technique, and cleared by a modified Spalteholz method. The extraosseous vascularity was through the branches of the three major regional arteries which entered the five nonarticulating surfaces of the bone. The major blood supply to the body was provided by the artery of the tarsal canal. The deltoid and sinus tarsi vessels provided significant minor sources of vascularity. The superior neck and posterior tubercle vessels supplied small areas of the body, but did have anastomoses with the other arteries in some specimens. These vascular patterns correlated well with the reported incidence of avascular necrosis of the body of the talus following injury.

Barrier and Penetration scores in relation to some variables, such as muscular tone at rest, sensitivity to tickle, and body perception were studied in a group of 35 female subjects. While no correlations appear within the whole group of subjects between Barrier scores and the other variables, an inverse relation emerges between Penetration scores and muscular tone on the left side of the body. Dividing subjects on the basis of Barrier scores, three groups with different characteristics appear: 12 subjects with high Barrier scores show an inverse relation of Barrier scores with sensitivity to tickle on the right side of the body; 12 subjects with middle Barrier scores show a direct relation of Barrier scores with muscular tone and an inverse one with both latency of tickle on the right half of the body and body perception; 11 subjects with low Barrier scores show an inverse relation of Barrier scores with durations of tickle on both sides of the body.
