Cyberstalking, personal privacy, and moral responsibility

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.     

Teacher and child variables as predictors of academic engagement among low‐income African American children

A causal model for understanding the complex interplay between student‐reported teacher behaviors, student self‐systems, and student engagement was tested. One hundred seventeen African American students in grades 1 through 12 completed a comprehensive questionnaire regarding teacher context, self, and engagement variables. A series of hierarchical regression analyses were conducted to test the hypothesized mediation models and to construct a path model. Most hypotheses were supported. Student self‐system variables (perceived competency and autonomy) mediated relations between teacher context (structure and autonomy support), and engagement. Contrary to predictions, however, teacher involvement exerted a strong and direct effect on student engagement even when controlling for grade level and self‐system variables. Given existing research showing that African American students are at risk for low teacher involvement and that engagement is critical for academic success, research and intervention strategies are urgently needed to promote teacher involvement with these students. © 2002 Wiley Periodicals, Inc.     

Role of essential trace minerals on the absorption of heavy metals with special reference to lead

Heavy metals are important toxicants known to exert adverse effects in humans and animals, given sufficient exposure and accumulation in the body. This has a great concern both at personal and public health risk. Heavy metals are also known to interact with the essential trace minerals at the level of absorption and also during the metabolism. The adverse effects of the absorbed and accumulated heavy metals include neurological, reproductive, renal and hematological systems. Children are more sensitive than adults to the effects of lead. Efforts are made to understand the mechanism of the interactions of heavy metals with essential trace minerals at the level of absorption. With available sensitive and specific methodologies like Anodic Stripping Voltammetry for the evaluation of the levels of toxic heavy metals such as lead, cadmium, mercury etc., better understanding of heavy metal absorption is made possible. Due to the poor nutritional standards, risk of heavy metal exposure is still a major concern in developing countries. Studies carried out by the author have provided evidence towards the understanding of the prevailing mechanisms of metal-metal interaction at the intestinal level. During growth and development the demand for the essential minerals being at higher level, differentiation of various essential metals and heavy metals pose an inherent problem due to certain common properties shared by them. With this approach to the problem of heavy metal toxicity, it is preventable not only with environmental intervention but also by the nutritional management.     

The uniqueness debate in computer ethics: What exactly is at issue, and why does it matter?

The purpose of this essay is to determinewhat exactly is meant by the claimcomputer ethics is unique, a position thatwill henceforth be referred to as the CEIUthesis. A brief sketch of the CEIU debate is provided,and an empirical case involving a recentincident of cyberstalking is briefly consideredin order to illustrate some controversialpoints of contention in that debate. To gain aclearer understanding of what exactly isasserted in the various claims about theuniqueness of computer ethics, and to avoidmany of the confusions currently associatedwith the term ``unique', a precise definition ofthat term is proposed. We then differentiatetwo distinct and radically differentinterpretations of the CEIU thesis, based onarguments that can be found in the relevantcomputer ethics literature. The twointerpretations are critically analyzed andboth are shown to be inadequate in establishingthe CEIU thesis. We then examine and reject twoassumptions implicit in arguments advanced bothby CEIU advocates and their opponents. Inexposing and rejecting these assumptions, wesee why it is not necessary to accept theconclusions reached by either side in thisdebate. Finally, we defend the view thatcomputer ethics issues are both philosophicallyinteresting and deserving of our attention,regardless of whether those issues might alsohappen to be unique ethical issues.     

Envisioning the industrial present: pathways of cultural learning in Luxembourg (1880s–1920s)

Abstract

This article examines how and to what extent Luxembourg society was “exposed” to visual representations of the prospering steel industries and labour and working-class culture(s) from the 1880s until the 1920s – a period of massive industrialisation – and how it thus gradually “learned to labour”. Indeed, modern visual media were seen as ideal catalysts for the circulation, transmission, and production of meaning, since they were considered to be appealing, objective, direct, and capable of inspiring the imagination. The article takes the reader through various mundane moments and events of industrial enculturation (annual funfair, slide lecture, vocational school, etc.) and engages with different “technologies of display” (photographs, fair albums, postcards, scale models, etc.) that subtly calibrated, conveyed, and inculcated the new industrial reality “through the eye” and, in the process, (re)produced national identifications. By zooming in on these different “visual encounters” with industry and by bringing these isolated encounters together in one story, the article (re)constructs a “learning route” – one among many possible pathways through this huge dynamic field of learning resources (or, “cultural ecology”) – and thus suggests how (informal) “cultural learning” might have taken place at the time. While accompanying us on this journey, the reader gains insights into how this field of resources evolved and how the industrial present was (re)framed, visually performed, and (re)configured over time.     

Building and sustaining communities that prevent mental disorders: Lessons from the field of special education

Quietly, at least beyond the awareness of many psychologists, a relatively new technology based on school‐wide behavior management strategies has emerged in special education to answer the call to build healthy communities. The success of these strategies in changing the practices of school systems and creating positive school climates may offer insights for school psychologists interested in preventing mental disorders and promoting health on a broader scale. Spreading the influence of school‐wide behavior supports to ensure that all schools provide the nurturing environment needed to promote academic and life success for all children is an important and immediate goal. Beyond the school, the challenge will be to implement and evaluate the impact of positive behavior supports in other connected communities. The present article reviews the history and present state of school‐wide behavior supports and prevention research, limitations of current practice, and opportunities for integrating school‐wide programs with psychological science and practice. © 2006 Wiley Periodicals, Inc.

The development of cognitive maps of large- and small-scale spaces.

Kindergartners, second, and fifth graders made repeated trips through a large- or small-scale model town, and then constructed from memory the layout of buildings in either a large- or small-scale space. Accuracy of construction increased as a function of developmental level and repeated trips through the town. Children's constructions were most accurate when they were tested in the same-scale environment as that in which they developed their spatial knowledge; accuracy was impaired significantly only when children were exposed to a small space and then reconstructed in a large space. Results were interpreted in terms of a "competence-load trade-off."     

A research synthesis of magnet school effect on student outcomes: Beyond descriptive studies

Characterized by thematic instructional programs and voluntary enrollment, magnet schools are often the result of a neighborhood schooling effort to increase racial integration and academic achievement. With the continued expansion of magnet schools, it is critical that stakeholders have a comprehensive research synthesis of their potential impact. This article reviews and aggregates findings from 18 studies that evaluate magnet schools’ influence on student outcomes. Emphasis is given to the results of lottery-based studies and those utilizing prior achievement and demographic controls. Though results across studies vary substantially, effects are generally positive, particularly for magnet secondary schools.
