This essay examines some ethical aspects of stalkingincidents in cyberspace. Particular attention is focused on the Amy Boyer/Liam Youens case of cyberstalking, which has raised a number of controversial ethical questions. We limit our analysis to three issues involving this particular case. First, we suggest that the privacy of stalking victims is threatened because of the unrestricted access to on-linepersonal information, including on-line public records, currently available to stalkers. Second, we consider issues involving moral responsibility and legal liability for Internet service providers (ISPs) when stalking crimesoccur in their `space' on the Internet. Finally, we examine issues of moral responsibility for ordinary Internet users to determine whether they are obligated to inform persons whom they discover to be the targets of cyberstalkers. 相似文献

Students’ sense of belonging presents an essential resource for academic and health outcomes, whereas social exclusion at school negatively impacts students’ well-being and academic performance. Aiming to understand how feelings of school-related belonging and exclusion shape the structural brain development, this study applied longitudinal questionnaire-based data and MRI data from 71 adolescent students (37 females, Mage at t1 = 15.0; t2 = 16.1 years). All were white participants from Germany. Voxel-based morphometry revealed only an association of social exclusion (and not of belonging) and gray matter volume in the left anterior insula: From t1 to t2, there was less gray matter decrease, the more social exclusion students perceived. School-related social exclusion and disturbed neurodevelopment are thus significantly associated. 相似文献

The purpose of this investigation was to see whether children's understandings of different types of beliefs develop concurrently. Children of 3, 4, and 5 years of age were told or shown that child story characters held beliefs different from their own or from one another, not only concerning matters of physical fact ("false beliefs"), but also concerning morality, social convention, value, and ownership of property. In contrast to the older subjects, most 3-year-olds had difficulty in attributing to others deviant beliefs of all types, except perhaps ownership, sometimes even after having been told repeatedly what the other child believed. In addition, intercorrelations among different belief tasks were positive and substantial. It was suggested that an emerging representational conception of the mind is what enables older preschoolers to understand the possibility of belief differences of all these types. 相似文献

Pigeons pecked keys for food reinforcers delivered by several variable-interval and multiple variable-interval schedules. The rates of responding emitted during the simple schedules were not systematically different from the rates emitted during the multiple schedules when the components of the multiple schedule were identical. The rates of responding emitted during the components were usually greater than the rates emitted during comparable simple schedules when the components were more favorable than the added components of the multiple schedules. Response rates during the components were not significantly lower than those during comparable simple schedules when the components were less favorable. The observation of higher rates of responding during the more favorable components conforms to a prediction of several additive theories (e.g., Rachlin, 1973) but violates a prediction of Herrnstein’s (1970) theory. However, the additive theories are brought into question by the fact that changing the location of the discriminative stimuli did not change the pattern of results. 相似文献

Popular and accessible before television and the internet, picture books capture the context of the time they were created and influence the generations of children who consume them. Depictions of the natural world have changed across several generations of picture books as seen in illustrations of all 249 books of an influential collection, the Children’s Book Council of Australia Picture Book of the Year Awards shortlists from 1955 to 2014. This study found that natural environments became proportionally less present in picture books over time while depictions of built environments increased. The presence of wild animals and native Australian animals also decreased over time. Sustainability themes and more realistic depictions of wild animals and biodiversity increased over time which reflects a growing ecological or environmental awareness, and diversification of environmental themes in recent picture books of this prominent Collection. 相似文献

Although many educators recognize the importance of voice, fostering voice in those who have traditionally been voiceless
has been difficult. This article, like the program that it describes, tackles that challenge by having participants speak
for themselves. Specifically, the participants speak about their involvement in the first year of an alternative teacher education
project. In describing their involvement, the participants focus on their roles and relationships as well as the type of partnership
and collaboration that emerged from this project. 相似文献

This paper explores the basis and main characteristics of fine art as a subject discipline and looks at how these elements combine to create a distinctive and in many ways unique learning environment. Taking the premise that fine art as a subject discipline is concerned with encouraging the development of individual artistic practice and enabling the student to articulate and define the social and cultural context that they are working within, this paper considers how fine art students come to develop alternative ways of thinking, seeing and conceptualising. Referring to the Art and Design Subject Benchmark statements the paper argues that in a fine art education, a set pf principles, core characteristics, skills and abilities are combined to create a unique learning environment that gives its graduates a set of abilities that are particularly relevant to our complex society. 相似文献

The authors explore their experience of a course for long-term unemployed people and reflect as to whether the traits identified by Tom Bourner on readiness for action learning actually relate to their experience. They conclude that based on the obvious development by the members of the group over the course, they observed, in some small way, the kind of evolutionary process of becoming ready for action learning that Bourner seems to imply. 相似文献
