Using an inventory based on findings from several qualitative studies, this investigation developed eight dimensions distinguishing successful senior managers from those who had derailed. Results showed that bosses' ratings of 86 successful senior managers on the eight dimensions were significantly higher than those of 83 who had derailed, providing empirical support for many of the earlier qualitative findings. Comparing the successful managers to the derailed suggests dimensions otherwise overlooked which are important to consider when assessing managerial talent.  相似文献

This address briefly traces post-1940 U.S. science policy from the science policy agenda set forth by Vannevar Bush in 1945 through the recent congressional task force on science policy. Although there are many factors influencing science policy, the focus here is on presidential influence. The effects of U.S. science policy on science are traced by looking at funding patterns in general, as well as at those for behavioral science. The influence of politics on the ability of scientists to freely communicate scientific information is examined. Finally, the role of politics in scientists’ access to computing resources is explored. Presented here is a side of science not often seen by those at the bench.  相似文献

Although it has been suggested that the early play experiences of girls and boys may contribute to gender differences in cognitive and social development, empirical support for this hypothesis is limited. This paper reports the development of a system of toy classification and may permit a more programmatic investigation of this problem. One hundred adult subjects rated 50 children's toys on 12 “functional” dimensions. Results showed that these toys could be reliably described according to multidimensional similarities and that toys considered appropriate for girls differed in many ways from those considered appropriate for boys. Thus this system may allow us to test more systematically the hypothetical relationship between sex-typed toy play and the development of differential cognitive and/or social skills in girls and boys.  相似文献

This paper begins with a short tutorial on multidimensional scaling. The focus of the remainder of the paper is on the proper designing of research that will use multidimensional scaling analysis techniques and includes suggestions for the interpretation of results.  相似文献

Viloxazine, an aryl-oxypropanolamine type β-adreno-receptor antagonist, has been used in the treatment of depression. In a double-blind drug interaction study with flurazepam, a commonly used benzodiazepine hypnotic, viloxazine administered alone decreased the amount of time spent in REM sleep, increased the amount of time in the “light” stages of sleep, and increased the number of transitions to awake. However, no interactive effects of the combined administration of viloxazine and flurazepam could be detected.  相似文献

Eighty-four male and 84 female subjects, divided into high, moderate, and low groups on the basis of sex-role stereotyping, watched videotapes of two-person interactions where positive and negative assertive messages were sent by male and female actors to male and female receivers. Subjects rated the level of assertion and the social acceptability of each message. Results indicated that while all messages were rated as relatively assertive, negative messages were perceived as more assertive and less socially acceptable than positive ones. Subjects also rated male senders as more assertive than female senders when the message type was role inappropriate for the subjects but rated female senders as relatively more assertive when the message type was role appropriate for them. Messages from female senders were rated as more socially acceptable than messages from male senders. Finally, messages to male receivers were rated as more acceptable than messages to females, especially by male subjects when the sender was male. Thus, both sex-role stereotypes and situational expectations appear to influence perceptions of level of assertion, and more assertive messages are perceived as less socially appropriate.  相似文献
