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

The education for sustainability (EfS) literature espouses participatory, praxis-orientated, place-based and holistic approaches to teaching and learning. The introduction of a first-year EfS unit for pre-service teachers at James Cook University provided an opportunity to explore their attitudes toward EfS and their perceptions of the relevant aspects of the unit to their learning. In this mixed-methods study, pre-service teachers (N = 100) completed a Likert-style survey at the beginning and end of the unit that examined their attitudes toward EfS. Three pre-service teachers were also interviewed to explore further their perceptions and experiences, one semester after completing the unit. Significant improvements were found in pre-service teachers’ EfS self-efficacy, and familiarity with and interest in sustainability issues. Participants also perceived EfS to be relevant to their learning, particularly the praxis-orientated pedagogies in which they engaged, as they believed it developed their knowledge, skills and confidence to teach sustainability in schools. For one pre-service teacher, her experiences of EfS during her practicum enhanced its relevance, as she was able to link theory and practice. The implications of these findings for both teacher education and pedagogical practice for EfS in higher education are also discussed. 相似文献

For years, a popular explanation for women choosing to abandon studies in science, technology, engineering, and mathematics (STEM) has been their lack of aptitude. This study challenged that notion by integrating theories of cognitive style, academic emotion, self-efficacy, and motivation to explain students’ academic achievement and perseverance in STEM when transitioning to college. A sample of 1597 high school and junior college students participated. Exploratory and confirmatory factor analyses were first conducted to validate a reduced version of the cognitive style questionnaire. Structural equation modeling revealed that the cognitive style known as systemizing indirectly predicted STEM achievement and persistence by way of intrinsic motivation, learning anxiety, and self-efficacy, providing a new perspective for re-examining the gender gap in STEM.

This article focuses on a new form of governing that targets a selected group of teachers. Specifically, it analyses how the Swedish so-called advanced teacher reform is enacted at the local level and discusses its implications for teachers’ professionalism. The methodological approach enables a local analysis in a broader international policy context. Using characteristic elements from curriculum theory to analyse the relationship between different levels and elaborating on the linguistic turn of curriculum theory, three concepts are central in the analysis: enactment, linguistic criteria and professionalism. Empirically, the study draws on material from a two-year application process in a medium-sized municipality. The result demonstrates that the local enactment process is clearly influenced by transnational policy trends and that less allowance is made for teachers’ own experience-based knowledge in the second studied year. The linguistic analysis shows how the applicants using the ‘right concepts’ were selected to become ‘advanced teachers’. As complex and qualitative aspects disappeared from the agenda, this type of governing, with its standardized use of language, may reduce schools’ educational potential. Changes like this raise new questions about how schools can maintain and develop democratic and professional values whilst being exposed to new policy trends. 相似文献

Research has shown that autonomy support has positive effects on academic development, but no study has examined how systemising cognitive orientation is related to important outcomes for science students, and how it may interact with autonomy support. This prospective investigation considered how systemising and support from teachers and parents influence motivation, self-efficacy and science performance of science students. Totally, two hundred and eighty eight high school students (143 females and 145 males) completed surveys at two times and records of their achievements were collected. Teachers’ autonomy support and systemising were significantly positively related to motivation, self-efficacy and achievement over time, while parental support for autonomy was not directly related to the outcomes. Finally, two significant interaction effects showed that the relation of parental autonomy support to motivation and self-efficacy was moderated by systemising. This is the first study to demonstrate that autonomy support may be especially helpful for individuals with an intrinsic disposition in a domain. 相似文献

This paper deals with the leader-following consensus problem of multi-agent systems with the consideration that each agent can only transmit its position state to the neighbors at irregular discrete sampling times. In the proposed algorithm, a continuous-discrete time observer is designed for the continuous estimation of both position and velocity from the discrete position information of the neighbors. These estimated states are then used for designing a continuous control law which solves the leader-following consensus problem. Moreover, the dynamics of the leader is not fixed and can be controlled through an external input. The stability analysis has been carried out by employing the Lyapunov approach which provides sufficient conditions to tune the parameters according to the maximum allowable sampling period. The developed algorithm has been simulated and then tested on an actual multi-robot system consisting of three differential drive wheeled robots. Both simulation and hardware results validate the effectiveness of the control algorithm. 相似文献
