ABSTRACT

This paper examines the impacts of co-residence (admitting women to men’s colleges and men to women’s colleges) at the University of Oxford beginning in the 1970s. Co-residence increased the representation of women undergraduates at Oxford to near parity with men; the representation of women in academic positions rose but not as substantially as that of women undergraduates and postgraduates and today women comprise still only a third of academics in the colleges of the university; the fellowships of the former female colleges became genuinely mixed, the fellowships of the former male colleges more slowly; women are less likely to be appointed head of a former men’s college than are men to be appointed head of a former women’s college; the quality of Oxford undergraduates rose with the increased number of female undergraduates; and the quality of undergraduates in the former male colleges rose at the expense of the female colleges.  相似文献

This paper reports a study of pupils attitudes to Craft Design Technology (CDT), Technology (GCSE) and Technology A level in a Mid Glamorgan secondary school. Technology is regarded by the pupils as being intellectually demandng and having a high ‘employment value’. This seems to attract more able pupils (of both sexes) than would be the case for other CDT subject areas. Pupils perceive CDT: Technology to have the characteristics of Science subjects rather than those of Arts or Crafts. A significant proportion of female students in this case study are attracted to study A level Technology and investigations are continuing to identify the underlying reasons for this.  相似文献

Loneliness and Peer Relations in Young Children   总被引:13,自引:0,他引:13  
Recent studies indicate that feelings of loneliness and social dissatisfaction can be reliably assessed with third- through sixth-grade children, and that children who are sociometrically rejected by their peers are significantly more lonely than other children. The present research was designed (a) to examine whether loneliness could be reliably assessed in a population younger than previously studied, (b) to learn whether young children who are poorly accepted by peers report elevated levels of loneliness and social dissatisfaction, (c) to assess whether young children understand the concept of loneliness, and (d) to examine the behavioral characteristics of lonely young children. Kindergarten and first-grade children (N = 440) responded to a questionnaire about feelings of loneliness and social dissatisfaction in school. A subset of children (N = 46) were individually interviewed to assess their understanding of loneliness. To assess sociometric status and behavior, peers were asked to respond to various sociometric measures and behavioral assessment items. Teachers also provided behavioral information about children using a newly developed instrument. Results indicated that nearly all children understood loneliness, that loneliness was reliably assessed in young children, and that poorly accepted children were more lonely than other children. In addition, children who reported the most loneliness were found to differ from others on several behavioral dimensions.  相似文献

Two experiments attempted to establish vicious-circle behavior through fear motivation combined with secondary punishment. In Experiment 1, rats were trained with two CSs, a tone and a buzzer, paired with shock in different contexts. Secondary punishment based on delay and trace conditioning procedures facilitated running in fear-motivated rats, relative to four control groups. In Experiment 2, rats were given pairings of a tone CS with shock, and a buzzer CS with a drop into a water tank. Fear-motivated rats which received secondary punishment during either 33% or 100% of test trials exhibited self-punitive running relative to a nonpunished (0%) group and a backward-conditioning control group. Results indicate that “all secondary” vicious-circle behavior can be established through Pavlovian conditioning, thus supporting a conditioned fear interpretation.  相似文献

The present experiment compared two methods of eliminating a classically conditioned response in dogs, extinction and reinforcement of nonsalivation, using both a within- and between-subjects experimental design. Eighteen dogs were trained for 16 days in Phase I, 16 days in Phase II, and 8 days in Phase III. In Phase I, each subject received classical conditioning training to two stimuli. In Phase II, Group 1 received extinction training to one stimulus and reinforcement of nonsalivation to the other stimulus. Group 2 received continued classical conditioning training to one stimulus and reinforcement on nonsalivation training to the other. Group 3 received continued classical conditioning training to one stimulus and extinction training to the other. In both the within- and between-subjects comparisons, responding to the stimulus associated with extinction was eliminated faster than responding to the stimulus associated with reinforcement of nonsalivation.  相似文献
