This article uses the NetCorps Jordan project as a case study of the ways in which Information Technology transforms social and economic life at the grass roots. Particular attention is paid to the role of gender in shaping such processes. In the end, this essay explores the motivations, the hopes and the results of one Arab country’s IT4 D experiment using the narratives of the participants as a guide. It is clear from the analysis below that culture, context and gender play a significant role in who gets to do what with IT.  相似文献

In a series of within-subject experiments employing a two-choice delayed conditional discrimination task, pigeons chose correctly more often when kind of correct choice and kind of reinforcer were perfectly correlated than when uncorrelated. Correct choice behavior fell to chance levels when the correlation was reversed or when it was removed by using only one kind of reinforcer. Implications for mediation theories are discussed, with the conclusion being that, although the possibility that instrumental mediators are present in this situation cannot be dismissed, the overall pattern of results indicates that classical mediators are of principal importance in this type of task.  相似文献

Prior work has shown that when the separate correct responses of a conditional discrimination are followed by different reinforcing outcomes, performance is enhanced relative to that obtained under the conventional, single-reinforcer procedure. Four experiments with pigeons yielded the analogous finding when the different outcomes were reinforcement and explicit nonreinforcement. Controls indicated that the results could not be attributed to the effects of intermittent reinforcement, to possible differences in cue duration, or to a variety of potential sources of conditioned reinforcement. An interpretation in terms of expectancy learning is proposed.  相似文献

In this investigation we examined the relation of children's reported feelings about school during kindergarten or first grade to their academic achievement at the end of fifth grade. Participants were children (N = 103) who lived in poverty during early childhood and who were placed on individualized education programs (IEPs) during their elementary school years. Results indicated that early feelings about school predicted fifth-grade outcomes above and beyond predictions based on an assessment of receptive language at age 5. Specifically, general positive feelings about school predicted higher fifth-grade literacy skills whereas feelings of greater competence in academics predicted higher fifth-grade math skills. The findings have implications for interventions with young children who have special learning needs, live in poverty, and report early ambivalent or negative feelings about school.  相似文献

A structured faculty professional development program which deliberately seeks to bring about change can yield lasting benefits for both the individual and the institution. Ten individuals who entered a program for the professional renewal of faculty between 1983 and 1987 were interviewed to discover what impact the program had on their professional development and on their contributions to the institution. Their experiences exhibit external and internal changes, with individuals being able to reflect upon their gains, contributions, and future directions. A basic model for support needed to bring about lasting change includes the elements ofpower, vision, structure, andresources.Joyce P.

As a noted author of childbirth education articles, books, and videotapes, Penny Simkin muses over the changes in maternity care during her career and the lessons she has learned. She searches for reasons to keep on working to bring normal birth to women, especially in an era when medical intervention based on editorials rather than evidence continue to increase.  相似文献

ABSTRACT

With increasing moves globally towards the professionalisation of teaching in Higher Education, there is growing interest in the role of accredited professional recognition schemes that provide professional development for established university teaching staff. In the UK, There are now over 120 professional recognition schemes, resulting in institutionally focused evaluation studies examining their impact. This article contributes to this emerging body of work; it draws on cross-institutional data and Foucauldian theorising to address two important questions. In what ways does engagement with an institutional professional recognition scheme impact on participants’ teaching development, and how does institutional culture influence that engagement? The data illustrate that whilst institutional culture drives engagement, it did little to promote teaching development. Across the case-study institutions, neo-liberalism agendas were apparent. Some staff felt pushed to achieve professional recognition in response to the increasing use of metrics to measure the student experience and to inform institutional standing in league tables. Whilst evidence shows the process of seeking accreditation can lead to an enhancement in teaching practices, caution must be taken to ensure that the professional development opportunities offered by accreditation schemes are fully realised.  相似文献

Studies of extinction in classical conditioning situations can reveal techniques that maximize the effectiveness of exposure-based behavior therapies. In three experiments, we investigated the effect of varying the intertrial interval during an extinction treatment in a fear-conditioning preparation with rats as subjects. In Experiment 1, we found less fear at test (i.e., more effective extinction) when extinction trials were widely spaced, relative to intermediate or massed extinction trials. In Experiment 2, we used an ABA renewal procedure and observed that spaced trials attenuated renewal of conditioned fear relative to massed trials. In Experiment 3, we used a similar design, but instead of changing the physical context at the time of testing, we interposed a retention interval after the extinction treatment to produce a change in the temporal context. The results showed less spontaneous recovery of fear after spaced than after massed extinction trials. These results suggest that extinction is more enduring when the extinction trials are spaced rather than massed. Although the benefits of spacing trials are small when there is no contextual change from extinction to testing, a change in either physical or temporal context following massed extinction trials leads to a recovery from extinction, which is reduced when the trials are spaced.  相似文献
