Within a broader project on children's sexual thinking, 838 children and 5 to 15 years in Australia, England, North America, and Sweden were interviewed (Goldman & Goldman, 1980, 1981.) Two items were focused upon: how children perceive differences between mothers and fathers, and how children perceive the roles of mothers and fathers. Five categories of differences between mother and father were located. Attitudinal differences positively correlated with age in all four countries. Parental roles contained five response categories. All categories show the traditional sex bias. Mother is seen by all children as predominantly concerned with domestic duties, care of children, and low status occupations, while father is seen overwhelmingly in a leisure role, as occupier of high status occupations, and playing authority-leadership roles in the family. Implications are discussed in terms of the need for society to accept and promote androgynous persons.  相似文献

Theoretical and technical considerations of measuring puff and inhalation volumes during cigarette smoking are reviewed. Measures of smoking behavior using a flowmeter and inductance plethysmography are described and demonstrated with seven subjects smoking over a 3-to 4-h period. Puff volume and duration, inhaled volume and duration, interpuff and intercigarette interval, and number of puffs varied for each individual over the session. The ratio of puff volume to inhaled volume changed with successive cigarettes. Smokers adjust the concentration of smoke by blending air with the smoke. Thus, to completely characterize smoking behavior, the volume of smoke and air inhaled into the lungs must be measured directly.  相似文献

This investigation examined the relationship among subordinate upward-influencing behavior, superior interpersonal stress, and superior performance within a health care setting. It was predicted that hard upward-influencing behavior as exerted by subordinates would be (a) inversely related to subordinate ratings of health care manager performance and (b) positively associated with health care manager interpersonal stress. Data were collected from 76 females and 4 males who were subordinates to 10 health care managers. All were employees in a 116-bed not-for-profit acute care community hospital. Subordinates completed the Satisfaction With My Supervisor Scale (Scarpello & Vandenberg, 1987), work unit and health care manager effectiveness scales (Bass, 1985b), and Form M of the Profiles of Organizational Influence Strategies (Kipnis & Schmidt, 1982). Interpersonal stress was assessed by the 10 health care managers' completion of the Responsibility for People subscale of the Stress Diagnostic Survey (Ivancevich & Matteson, 1980). The results generally supported the two hypotheses. The implications of these findings were discussed. It was recommended that organizations should encourage rational subordinate upward-influencing behavior to reduce interpersonal stress and promote performance.  相似文献

Conducted a community survey in the Fall of 1984 in a sample of high unemployment blue-collar census tracts in southeastern Michigan. Results of earlier analyses using these data showed that involuntarily unemployed workers had significantly elevated levels of depression, anxiety, somatization, and self-reported physical illness relative to a stably employed comparison group (Kessler, House, & Turner, 1987). Results presented in this paper document that this relationship is modified by social support (as measured by social integration and the availability of a confidant), self-concept, and various coping processes. Further analyses allowed us to determine the way in which these modifiers operate. The modifying effects of social support and coping operate primarily by buffering the impact of unemployment-related financial strain on the health outcomes. Self-concept operates primarily by attenuating vulnerability to other stressful life events. The implications of these results for the design and implementation of preventive interventions are discussed.  相似文献

The effect of prior juror service on jury sentencing was investigated in an archival study of 143 criminal trials resulting in convictions. Trials took place over two calendar years in a state circuit court requiring jurors to serve 30-day terms. Jurors sentenced defendants in each case according to a set of guidelines determined by trial judges. The severity of the sentences imposed by jurors was rated by 101 subjects on a scale of 1 (least severe) to 100 (most severe). The results indicated that the more experienced juries gave significantly more severe sentences than did the less experienced juries. This finding was unchanged when civil court experience was considered in addition to criminal court experience. Possible interpretations of these results are discussed.  相似文献

Aversive and deprivation procedures for controlling and reducing challenging behaviors have received increasing attention. Many states have adopted guidelines on the use of these procedures treating persons with developmental disabilities. The Minnesota state rule promulgated in October, 1987 requires reviews from both local and state-wide review committees on permitted, but controlled procedures. Data generated from state-wide committees revealed that (a) state operated regional treatment centers (RTCs) employed individual habilitative training programs with controlled procedures more frequently than community-based agencies (b) a higher proportion of RTC submissions were for treatment of self-injury than submissions from community services, and (c) RTCs had a higher usage of mechanical restraints than community facilities with both services settings using manual restraints more frequently than all other controlled procedures combined. Reasons for the above differences in the two service settings were discussed.  相似文献

One effort to specify cognitive mediators related to dysfunctional emotional responses has been made by Ellis, who proposed that certain irrational beliefs elicit maladaptive emotional reactions. In order to test Ellis's hypotheses in a nonclinical sample, the Irrational Beliefs Test, two anxiety inventories, the MMPI-168, and a locus of control scale were completed by 32 male heavy social drinker undergraduates, who then kept daily records of their anxiety, anger, unhappiness, and drinking behaviors for 7 months. Four factors underlay the 10 beliefs but did not necessarily correlate with dysphoric affect. Certain irrational beliefs predicted daily unhappiness ratings over the 7-month period and daily anger ratings over 3 months, but the beliefs exhibited only a weak relationship with daily general anxiety ratings. Irrational beliefs, especially worrying about approval and competence, were strongly related to test anxiety and Spielberger's trait anxiety measure, were somewhat related to social anxiety and general anxiety, were minimally related to locus of control and social desirability, and were essentially unrelated to the MMPI-168's measures of depression and anxiety and to drinking behaviors. Although 2 of the irrational beliefs failed to exhibit relationships with negative affect, the other 8 show the predicted relationships to moods, providing support for a cognitive mediational model of maladaptive emotions in a nonpathological population.This research was partially supported by grants from the Alcoholism and Drug Abuse Institute, University of Washington, Seattle, from a National Institute of Mental Health small grant AA03947-01, and from a National Institute of Alcohol Abuse and Alcoholism postdoctoral training fellowship No. 1T32AA07171-01. We would like to thank Jean Chapman, Ph.D., for her advice on the statistics and Dorothy Knapp, Ph.D., for her painstaking scoring and coding of all the data records.  相似文献

To assess the influence of a televised model's vocalizations on the vocal patterns of infant viewers, 32 infants at 6 months of age were presented either a televised adult model repeating a novel phoneme pattern (/ba/ba/ba/ba) or a control televised presentation of adult conversation selected from typical daytime programming. Sequential analyses of infant vocalizations revealed that infants exposed to the televised model altered their vocalization pattern, as indicated by a significant increase over base line levels in their production of a patterned series of discrete vocalizations. Infants exposed to the televised conversation showned no increase in this pattern of vocalization, and none of the infants in the study produced the novel phoneme (/ba/). The results indicate that televised presentation of discrete, repeated vocalizations can have an influence on the vocalization pattern of infants. The potential role of television in infant development is discussed.  相似文献

Patterns of cigarette smoking, treated as series of discrete events in time, were investigated with a variety of quantitative techniques designed to characterize individual subject smoking series and to illuminate the relationship between cigarette smoking and environmental events. Data were collected from a total of 35 subjects who were either participants in residential laboratory studies or in a smoking cessation program. Cigarette smoking events were found to be fairly irregularly distributed with respect to time within individual subject series. However, strong dependencies were found between the occurrence in time of individual acts of cigarette smoking and coffee drinking. In addition, the distribution and frequency of smoking events throughout one-hour activity sequences were found to be dependent upon the nature of the activity, and the temporal scheduling of activities was found to affect several quantitative indices of smoking patterns.  相似文献
