Bullying and victimisation remains a pervasive problem within the nation’s schools. International research has indicated that students who are enrolled in special education curricula are victimised and perpetrate more bullying than their general education peers. Few empirical studies have examined bullying and victimisation rates among American schoolchildren within special education programmes. The current study examined rates of bullying and fighting perpetration and victimisation among middle‐school students (n = 7331) and high‐school students (n = 14,315) enrolled in general education and special education programmes. As hypothesised, students in special education reported greater rates of bullying and fighting perpetration, and victimisation than general education students. Students who were in self‐contained classrooms reported more perpetration and victimisation than those in inclusive settings. Fighting perpetration was similar for younger and older students in special education settings, whereas fighting perpetration was lower for older students, versus younger students, in general education. 相似文献

Before there was the digital divide there was the analog divide– and universal service was the attempt to close that analogdivide.
Universal service is becoming ever more complex in terms ofregulatory design as it becomes the digital divide. In order to
evaluatethe promise of the next generation Internet with respect to the digitaldivide this work looks backwards as well as
forwards in time. Byevaluating why previous universal service mechanisms failed andsucceeded this work identifies specific
characteristics ofcommunications systems – in particular in billing and managinguncertainty – and argues that these characteristics
underliesuccess or failure in terms of technological ubiquity. Developing a setof characteristics of services rather than
a set of services is afundamental break with the tradition of universal service. In fact, theimplications of our proposal
is that basic characteristics in theoffering of the service rather than the absolute price are critical toclose the digital
divide: certainty of total charge, ability to avoiddeposits or disconnection via best effort service, and payer-basedcontrol
of all charges. While all of these principles sound obvious infact none of these hold in the telephony network. Universal
service hasevolved from common carriage (serve all with no discrimination) to aright to basic services (100% penetration).
Universal service isnow discussed as the digital divide, as the access to information asopposed to services becomes increasingly
critical. However, we arediscussing in this paper access to the bits and the network rather thanaccess to the information
(or intellectual property) once connected. Theprovision of universal service is seen as a technical problem only in thatthe
technology costs money – universal service debates have longbeen the domain of economists. Yet the design of protocols has
been thedomain of engineers, the building of systems the corporate domain, andthe discussion of equity the interest of ethicists.
The design ofprotocols can define the parameters of the corporate decision-makers,the variables of the economist, and the
questions for the ethicist. Thedesign decisions made at the fundamental levels can make communicationsequity more or less
likely. In this work I focus on the design ofprotocols for the next generation Internet, protocols which willfundamentally
change the best-effort nature of Internet services.Building on the economic and ethnographic work of others I argue thatthe
effects of protocols adoption on universal service can be predictedto some degree. By examination of past and current technologies
Iexamine a set of technical mechanisms to determine how such mechanismsmight harm or enhance universal service. I define each
mechanism (e.g.denial of entry) and offer observations about each particularmechanism's implicit pricing assumptions. I close
with a discussion ofinterest to ethicists and regulators on evaluating communicationsprotocols with respect to universal access.
Protocols for developingmultiple qualities of service for packet-switched networks have focusedon economic efficiency (e.g.
Mackie-Mason, 1995; Choi, Stahl &Winston, 1997; Shapiro & Varian, 1998), billing to encouragewidespread adoption of network
innovations (e.g. Xie & Sirbu, 1985)and billing in a manner consistent with the underlying network (e.g.Clark, 1996). Here
we examine a set of protocols which include varyingquality of service mechanisms with respect to the compatibility of theprotocols
with universal access. 相似文献

The relation of positive affect to attention and learning was examined in 5-, 7-, and 9-month-olds (N = 84). Affect and attention were assessed while the infants inspected a photograph. Affect was rated globally, for overall mood, and specifically, for amount of time smiling. Attention was indexed by the duration of the infant's longest (or peak) look, a measure previously linked to differential cognitive performance. At all ages, positive affect (shown by approximately half the infants) was associated with long look durations and slower learning, as assessed on a task in which infants learned to distinguish a familiar face from a series of novel faces. By contrast, neutral affect was associated with short looks and faster learning. Affect and look duration had synergistic effects, in that learning was faster than expected for infants who displayed both short looks and neutral affect. These findings are compatible with adult research that links positive affect to less analytical processing, and provide the first evidence that affect may be associated with the speed of processing differences implicated in short and long looking. 相似文献

Using group work as a way of meeting children's individual learning needs is becoming more widespread in a variety of schools. Richard Rose, head of Wren Spinney School, Kettering, Northamptonshire LEA, and a member of the National Curriculum Development Team (SLD) at Cambridge Institute of Education, describes a strategy for promoting group work in schools for pupils with severe learning difficulties. 相似文献

OBJECTIVES: Despite the growing use of online databases by clinicians, there has been very little research documenting how effectively they are used. This study assessed the ability of medical and nurse-practitioner students to answer clinical questions using an information retrieval system. It also attempted to identify the demographic, experience, cognitive, personality, search mechanics, and user-satisfaction factors associated with successful use of a retrieval system. METHODS: Twenty-nine students completed questionnaires of clinical and computer experience as well as tests of cognitive abilities and personality type. They were then administered three clinical questions to answer in a medical library setting using the MEDLINE database and electronic and print full-text resources. RESULTS: Medical students were able to answer more questions correctly than nurse-practitioner students before and after searching, but both had comparable improvements in the number of correct questions before and after searching. Successful ability to answer questions was also associated with having experience in literature searching and higher standardized test-score percentiles. CONCLUSIONS: Medical and nurse-practitioner students obtained comparable benefits in the ability to answer clinical questions from use of the information retrieval system. Future research must examine strategies that improve successful search and retrieval of clinical questions posed by clinicians in practice. 相似文献

Medium- and long-term strategies for deploying resources in Higher Education are discussed in the context of avoiding any reduction in the quality and quantity of educational provision, and, at the same time, meeting appropriate financial criteria. The paper emphasises the need to maximise the use of existing staff through redeployment, retraining and staff development. New appointments should be strictly controlled through part-time and fixed-term contracts. Staffing levels may be reduced through early retirement and redundancy, although in some situations, the sharing, movement or exchange of staff between institutions may be an alternative possibility. Non-staff costs are analysed in relation to teaching, administration, accommodation and ancillary activities. The principal of good house-keeping is advocated in relation to these costs, with a clear recognition of those costs which relate to academic standards and legal obligations. 相似文献
