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

This article explores recent developments inthe regulation of Internet speech, inparticular, injurious or defamatory speech andthe impact the attempts at regulation arehaving on the `body' in the sense of theindividual person who speaks through the mediumof the Internet and upon those harmed by thatspeech. The article proceeds in threesections. First, a brief history of the legalattempts to regulate defamatory Internet speechin the United States is presented; a shortcomparative discussion of defamation law in theUK and Australia is included. As discussedbelow, this regulation has altered thetraditional legal paradigm of responsibilityand, as a result, creates potential problems forthe future of unrestricted and even anonymousspeech on the Internet. Second, an ethicalassessment is made of the defamatory speechenvironment in order to determine which actorshave moral responsibility for the harm causedby defamatory speech. This moral assessment iscompared to the developing and anticipatedlegal paradigm to identify possible conformityof moral and legal tenants or to recognize theconflict between morality and law in assigningresponsibility to defamatory actors. Thisassessment then concludes with possiblesuggestions for changes in the legal climategoverning the regulation of defamatory speechon the Internet, as well as prediction of theresult should the legal climate continue todevelop on its present course. This is not tosuggest that all law, or even the law ofdefamation, be structured to reflect thesubjectivity of a moral construct, but since itis the authors position that the legalassignment of liability in online settings ismisaligned, this reflection can serve asbeginning reassessment of that assignment. 相似文献

Although teaching has been described as a profoundly emotional activity, little is known about the emotional demands faced by teachers or how this impacts on their well-being. This study examined relationships between ‘emotional labour’, burnout (emotional exhaustion, depersonalisation and personal accomplishment) and job satisfaction in a sample of UK teachers. Also examined was whether workplace social support moderated any relationships found between emotional labour and strain. The relationship between job experience and emotional labour was also investigated. Six hundred and twenty-eight teachers working in secondary schools in the UK completed questionnaires. Significant associations were observed between emotional labour and all outcomes, with a positive relationship found between emotional labour and personal accomplishment. Some evidence was found that social support mitigates the negative impact of emotional demands on emotional exhaustion, feelings of personal accomplishment and job satisfaction. More experienced teachers reported higher levels of emotional labour. Findings highlight the need for teacher-training programmes to raise awareness of the emotional demands of teaching and consider ways to enhance emotion regulation skills in experienced as well as recently qualified staff. 相似文献

This study considers how institutional histories of admitting women are associated with present college experiences, and uses data from the Wabash National Study of Liberal Arts Education to compare the experiences of women at women’s colleges or former women’s colleges to those of women at former men’s colleges and colleges that have always been coeducational. Results indicate that women attending former men’s colleges and colleges that have always been coeducational seem to experience similar or greater frequency and quality of student–faculty interaction and exposure to good teaching practices, compared to women attending women’s or former women’s colleges. Results also suggest that considering the gender enrollment histories of colleges and universities may provide valuable context for evaluating the experiences of women at women’s colleges and coeducational institutions. 相似文献

Designed-based research principles guided the study of 51 secondary-science teachers in the second year of a 3-year professional development project. The project entailed the creation of student-centered, inquiry-based, science, video games. A professional development model appropriate for infusing innovative technologies into standards-based curricula was employed to determine how science teacher’s attitudes and efficacy where impacted while designing science-based video games. The study’s mixed-method design ascertained teacher efficacy on five factors (General computer use, Science Learning, Inquiry Teaching and Learning, Synchronous chat/text, and Playing Video Games) related to technology and gaming using a web-based survey). Qualitative data in the form of online blog posts was gathered during the project to assist in the triangulation and assessment of teacher efficacy. Data analyses consisted of an Analysis of Variance and serial coding of teacher reflective responses. Results indicated participants who used computers daily have higher efficacy while using inquiry-based teaching methods and science teaching and learning. Additional emergent findings revealed possible motivating factors for efficacy. This professional development project was focused on inquiry as a pedagogical strategy, standard-based science learning as means to develop content knowledge, and creating video games as technological knowledge. The project was consistent with the Technological Pedagogical Content Knowledge (TPCK) framework where overlapping circles of the three components indicates development of an integrated understanding of the suggested relationships. Findings provide suggestions for development of standards-based science education software, its integration into the curriculum and, strategies for implementing technology into teaching practices. 相似文献

Findings are presented from the first randomized control trial of the effects of encouraging symbolic gesture (or “baby sign”) on infant language, following 40 infants from age 8 months to 20 months. Half of the mothers were trained to model a target set of gestures to their infants. Frequent measures were taken of infant language development and dyadic interactions were scrutinized to assess mind‐mindedness. Infants exposed to gesture did not differ from control conditions on language outcomes; thus, no support was found for previous claims that encouraging gesturing with infants accelerates linguistic development. Microgenetic analysis revealed mothers in the gesture training conditions were more responsive to their infants' nonverbal cues and encouraged more independent action by their infant. 相似文献

A stress management program was evaluated in sixth-grade classes of an urban public and a suburban parochial school. Sample 1, from the urban public school, and Sample 2, from the suburban parochial school, received pre- and posttests. Sample 3, from the suburban parochial school, was divided into pretest-only and posttest-only groups. Six self-esteem and 1 each stress and social-skills children's self-ratings and 1 each teachers' ratings of children's overall stress management and stress measures were used. All 10 measures showed improvement in the Samples 1 and 2 independently. Findings in Sample 2 replicated the positive effects in Sample 1. In both sixth-grade classes, children's stress level (self- and teachers' ratings), children's social skills and self-esteem self-ratings, and teachers' ratings of children's stress management skills improved significantly. Sample 3 posttest-only group scores did not differ significantly from the posttest scores of Sample 1 and 2 children. Rival hypotheses (e.g., history, maturation, testing) appeared implausible. Results support using skills-oriented stress management programs in regular grade school classes. 相似文献

Much literature has been devoted to theoretical explanations of the learning processes of older adults and to the methods of teaching best utilized in older populations. However, there has been less focus on the education of older adults who reside in assisted and independent living communities (AICs), especially with regards to information and communication technology (ICT) education. The purpose of this study is to determine whether participants' attitudes and views towards computers and the Internet are affected as a result of participating in an eight-week training program designed to enhance computer and Internet use among older adults in such communities. Specifically, we examine if ICT education specially designed for AIC residents results in more positive attitudes towards ICTs and a perceived decrease in factors that may limit or prevent computer and Internet use. We discuss the implications of these results for enhancing the quality of life for older adults in AICs and make recommendations for those seeking to decrease digital inequality among older adults in these communities through their own ICT classes. 相似文献
