Examined age and sex trends in emotional intensity in 432 Ss from adopting and nonadopting biological families. It was hypothesized that younger adults and females would report greater average levels of both positive and negative affect over time, as has been demonstrated in past research. 242 Ss (parents and offspring) completed a battery of mood scales. 190 Ss completed an affect intensity measure and a general behavior inventory. In support of the hypothesis, women scored higher on measures reflecting emotional intensity and manifestation of cyclothymic symptoms, and the scores on these measures decreased through the adult life span for both males and females. Potential reasons for the differences in emotional intensity are discussed. These include biological causes, cultural expectations, and current life experiences.

82 females from 10th, 11th, and 12th grades in a rural high school provided responses on identity status development (diffusion, foreclosure, moratorium, and identity achievement status) and perceived parental socialization styles using the Objective Measure of Ego-Identity Status Scales and a questionnaire on parental socialization. Psychometric reevaluation of the identity status instrument (originally normed with older adolescents) and the perceived childrearing items indicated appropriateness with middle-adolescent-female samples. Age difference comparisons show that although the onset of a foreclosed status may begin during the high school years, middle adolescence is not a period of dramatic age differences. The relationship between socialization styles and identity status comparisons reveals evidence for perceived socialization practices by mothers and fathers that significantly differentiate the identity status groups.

A pattern recognition system has been developed which is capable of recognizing high contrast two-dimensional visual patterns and which is insensitive to the translation, rotation and size of a pattern. The unique characteristics of the system are its speed, its low cost and the fact that it is completely self-contained.
A new technique for image recognition, suitable for applications such as industrial robotics, is presented. The technique provides invariance to rotation, translation and magnification of the image. An intelligent camera system is used to input an image, to center it, to normalize it with respect to size and to convert it into polar coordinate form. The image is then integrated over r and θ to provide two orthogonal profiles. The input profiles are compared to the reference images using a threshold comparison technique designed to provide a simple hardware implementation. Rotation of the image is handled by a one-dimensional shifting of the radial profile.
Seven experiments were performed to test the system. The results of these experiments are discussed and possible improvements to the system are suggested. 相似文献
198 men and 413 women responded to random telephone surveys in Fargo, North Dakota and Memphis, Tennessee. Each S was given the Smoking Attitudes Survey, which assesses generalized health beliefs and health-related problems associated with smoking. Ss' knowledge of smoking-associated diseases and diseases not associated with smoking was also assessed. Stepwise regression analysis of composite knowledge scores revealed 4 predictors of the health consequences of smoking: education, race, smoking status, and income. Smokers reported less knowledge and less concern about health consequences of smoking, were more likely to be male, and were more concerned about health consequences of cholesterol. The best predictor of smokers who had never attempted cessation was their greater concern over weight control, compared with smokers with a history of smoking-cessation attempts.

Conducted an intensive, case-by-case assessment of life-styles of a sample of religious students. We identified differing styles of religiousness and made comparisons by means of tests and interviews between subgroups whose subjects manifested differing religious life-styles. Those subjects with continuous religious development and mild religious experiences appeared to be healthier than those with discontinuous development and intense religious experiences; however, intense religious experiences tended to enhance the adjustment of those who experienced them. There was no evidence in the group as a whole for an overall negative or positive correlation between religiousness and mental health, but some modes of religious involvement appeared to be related to disturbance, whereas other modes appeared to be related to enhanced stability and resilience. Because causality in these relations remains uncertain, we generate hypotheses concerning further studies of life-styles and adjustment. We also discuss implications for student counseling and development. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献
This paper presents an overview of the development of aeronautical satellite communi-cations over the past 30 years. The initial development of aeronautical satellite communications is de-scribed in the paper. The civil aviation growth and current unaccommodated communication systemsare discussed as well. The inherent shortcomings of present air-ground HF communications have hin-dered the development of civil aviation. but according to the Future Air Navigation Systems(FANS) concept aeronautical satellite communication-including Automatic Dependent Surveillance(ADS)-will be the key to eliminating the shortcomings of HF communication systems. Satellite-basedcommunication and surveillance will significantly improve air traffic control (ATC) over the oceanicand remote terrestrial airspace, and it will benefit civil aviation authorities, airlines as wel as passen-gers. This paper discusses the availability of system elements, and world wide trials, demonstrtionsand preoperational use of aeronautical satelli 相似文献
There are important differences in the physical properties of the cis and trans isomers of unsaturated long chain amines.
Because of these differences, it is desirable to know the ratio of the cis and trans isomers. This separation can be accomplished
by capillary column gas chromatography of the amine derivatives; however, the use of capillary columns is too slow for routine
analysis. It was found that the cis and trans isomers of unsaturated amines can be rapidly separated on packed columns containing
cyanopropyl-phenylsilicone liquid phases (Apolar 10C). The primary amines are converted to the trifluoroacetamides and separated
on 6- to 10-ft columns containing 10% Apolar 10C at 180 C. The technique has been applied to unsaturated long chain primary
amines and diamines. Useful information on the isomerization of these compounds during their synthesis can be obtained. 相似文献
This exploratory study examined gender differences among drug-abusing adolescents (N?=?2,281). Overall, male adolescents reported somewhat higher usage levels of various drugs than did female adolescents, and they had an earlier onset of regular marijuana use. In terms of clinical signs of problem severity, female adolescents showed higher scores than male adolescents on Physical Symptoms, Escape (with drugs), and Emotional Consequences (of drug use) scales when drug use levels were controlled. However, the relatively small magnitude of the significant differences, and the fact that many scales did not show group differences, suggest that male and female adolescents attending drug clinics share many similar features of adolescent drug abuse. Implications of these findings for the prevention and treatment of adolescent drug abuse are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献
