The study focuses on some of the correlates of workplace mobility of male workers aged 15 to 17, mostly apprentices, who were registered with the Skilled Department of the Youth Employment Bureau (Y.E.B.) for at least a year prior to the time of the field study. Data regarding these correlates, and longitudinal data concerning the sequence of job movements, were obtained in an interview held with a sample of those youths who resided in Tel-Aviv metropolitan area (n = 146) and from the Y.E.B.'s forms filled out in connection with their registration and job placements. Several measures of sociodemographic background, past work experience and present working conditions were included in the multiple correlation analysis. Controlling for longevity in the labor force, seniority in the first job emerged as the most efficient predictor of workplace mobility. Results suggest that the early stages of a young worker's process of occupational socialization are of importance in determining his future career decisions.  相似文献

Rates and patterns of key-press responding maintained under schedules in which responding resulted in intravenous injections of cocaine were studied in squirrel monkeys and rhesus monkeys. Each injection was followed by a 60- or 100-sec timeout period. Schedule-controlled behavior was obtained at appropriate cocaine doses in each species. Under FR 10 or FR 30 schedules, performance was characterized by high rates of responding (usually more than one response per second) in each ratio. Under FI 5-min schedules, performance was characterized by an initial pause, followed by acceleration of responding to a final rate that was maintained until the end of the interval. Under multiple fixed-ratio fixed-interval schedules, rates and patterns of responding appropriate to each schedule component were maintained. Responding seldom occurred during timeout periods under any schedule studied. At doses of cocaine above or below those that maintained characteristic schedule-controlled behavior, rates of responding were relatively low and patterns of responding were irregular. Characteristic fixed-interval responding was maintained over a wider range of cocaine doses than characteristic fixed-ratio responding. Complex patterns of responding controlled by discriminative stimuli under fixed-ratio or fixed-interval schedules can be maintained by cocaine injections in squirrel monkeys and rhesus monkeys.  相似文献

Environmental stimuli which are repeatedly associated with the nalorphine-induced withdrawal syndrome in morphine-dependent monkeys acquire the ability to produce a variety of conditioned behavioral and physiological responses. Morphine-dependent rhesus monkeys were studied under a fixed-ratio schedule where every tenth lever press produced a food pellet. After several pairings of a stimulus (light or tone) with intravenous injection of a dose of nalorphine which produced an immediate and severe withdrawal syndrome, onset of the stimulus alone produced conditioned suppression of lever pressing, heartrate decrease, vomiting and salivation. Conditioned suppression of responding and conditioned heart-rate changes persisted in post-dependent monkeys for one to four months after termination of chronic morphine treatment. No conditioned electrocardiogram, respiration or temperature changes were ever seen. A second group of morphine-dependent rhesus monkeys was studied under a schedule where every lever press produced an intravenous injection of morphine. After 10 pairings of a light with the intravenous injection of a dose of nalorphine which produced marked withdrawal signs and increased responding for morphine, presentation of the light and injection of sahne produced conditioned increases in responding for morphine. A third group of morphine-dependent rhesus monkeys was studied under a schedule where every nth lever press (n = 1 to 10) terminated a stimulus light associated with periodic injections of nalorphine or naloxone; lever-press responding was engendered and subsequently maintained. Thus, stimuli associated with the nalorphineor naloxone-induced withdrawal syndrome can either suppress, enhance or maintain behavior depending on the schedule conditions.  相似文献

BELIEFS ABOUT THE CONSEQUENCES OF MATERNAL EMPLOYMENT FOR CHILDREN   总被引:2,自引:0,他引:2  
A 24-item scale was developed to measure Beliefs about the Consequences of Maternal Employment for Children (BACMEC), including beliefs about both benefits (13 items) and costs (11 items). Studies of five samples ( n = 375) demonstrate that the total BACMEC scale and its subscales are highly reliable and have good convergent, divergent, and con-current validity. Scores on the Costs Subscale predicted greater sex-role traditionalism, women's employment status (not employed), and an older age of child at which mother's employment was deemed acceptable. Benefits scores predicted women's employment status (employed) and work hours (longer), younger age of child when maternal work is accept-able, and greater support for policies to aid working parents. The scales were not susceptible to a social desirability bias. Suggestions are provided for the use of the BACMEC scale in future research concerning employment and families.  相似文献

Somewhere between the image of psychoanalysis as suggestion and psychoanalysis as unearthing is that of analysis as negotiation. This is a picture of a mutual construction of reality by analyst and patient. Such an interaction allows for reciprocal input of the participants and a possible change in both. This paper sketches the role of negotiation throughout the entire process of treatment--from the initial rules, to the theory of the analyst, to the emergence of the transference, to the goal of the cure. The technique of psychoanalysis is said to lie in the process of negotiation.  相似文献

Jewish tradition established the Sabbath as a special day. Its observance was both part of a religious tradition and an example of psychological health. This article explores the values and attitudes that underlie Sabbath observance, identifies some of the themes and behaviors most characteristic of these observances, and relates these to current mental health practices.  相似文献
