We taught 4 students with profound multiple disabilities to use a microswitch communication system to request a change in recreational stimuli during social interactions with nondisabled peers. In Study 1, we conducted a preference assessment across a range of stimuli for each student. The most and least preferred stimuli were incorporated into microswitch communication system training in Study 2. During the second study, 3 of the 4 students (a) learned to use the microswitch communication system to control stimulus presentation, (b) more clearly differentiated their time among stimuli, and (c) increased their level of general alertness. Study 3 extended the use of the microswitch communication system to social interactions with nondisabled peers. Two students were more engaged in interactions when they chose when to change stimuli; 1 student was more alert when a peer chose when to change activities; a 4th student showed an undifferentiated pattern. The outcomes of the investigation are discussed in terms of the effects of controlling stimulus presentation on the behavior of students with profound multiple disabilities and the stability of preference hierarchies over time. 相似文献

Two studies analyzed the effects of preceding setting events on the problem behavior of students with severe disabilities. Using ABAB withdrawal designs, the occurrence versus nonoccurrence of preceding setting events was analyzed in relation to the frequency of problem behavior. Data were collected throughout a student's school day, with interventions focusing upon the elimination of setting events that occurred before school. The results indicate that (a) the occurrence of preceding setting events was related to higher frequencies of problem behavior and (b) interventions designed to eliminate preceding setting events were consistently associated with low frequencies of problem behavior. 相似文献

In order to determine the relationship between perceptions of injustice and support for workplace aggression, 139 subjects were presented with four scenarios representing different levels and types of injustice. Subjects then responded to an eight-item aggression scale. Support for aggressive behavior across the scenarios generally corresponded to the amount and type of perceived injustice; a procedural injustice scenario was perceived as the most unjust and led to the most support for aggression. Although the interpersonal and distributive injustice scenarios were seen as virtually identical in terms of injustice, there was significantly more support for aggression with interpersonal injustice. The strongest predictor of support for aggression in the justice scenarios, however, was simply the degree of support for aggression in a neutral, or control, scenario. It is suggested that employers need to be concerned both about fair and courteous relations with employees and also with identifying generally aggressive employees. 相似文献

This article presents statistical data depicting the employment of persons with disabilities at a federal installation using a recruitment intervention designed to increase the presence of persons with disabilities. The data were obtained by reviewing archival recruitment accessions that span 5 years (1999–2003). The organization under study is a highly technical Department of Defense organization constituted primarily of engineers and scientists and has been in existence and a major contributor in national defense for many years. Earlier recruitment data are not available. 相似文献

Ethical dilemmas are often not discussed in the dissemination of educational research. While the ethical guidelines for research
seem clear at first glance, a closer look at the intimate nature of qualitative research reveals that there are many ambiguities
or ‘grey’ areas where researchers must rely on their personal value systems. This article discusses the challenges faced by
an experienced educator, although novice researcher, in considering the ethical parameters of her own research with adolescents
with hearing loss. In particular, the grey ethical areas identified by the researcher include: (a) vulnerable population;
(b) researcher role confusion; (c) consent; (d) privacy, confidentiality, and anonymity; as well as (e) the nature of risk.
Based on the author’s own reflections on beginning the research process, the article presents possible pitfalls and ways of
overcoming the possibility of becoming immobilized by the ethical enigmas of research. 相似文献

This paper seeks to address the question of schooling for democracy by, first, identifying at least one form of social character, dependent, after Marcuse, on the historical emergence of a “new sensibility.” It then explores one pedagogical thread related to the emergence of this form of subjectivity over the course of the last two centuries in the west, and traces its influence in the educational counter-tradition associated with philosophical anarchism, which is based on principles of dialogue and social reconstruction as opposed to monologue and reproduction. The idea of a dialogical school has been made possible by a historical shift in adult views of child as interlocutor rather than “othered” object of adult formation—a shift that can be observed in an historical process of “closer approaches” between adult and child and a recognition of childhood and adulthood as forms of subjectivity that lie on a synchronous rather than a diachronic lifespan continuum. Finally the author identifies an archetype of “school” understood as a specific type of intentional community—an experimental zone in which participants are allowed and encouraged, through explicitly dialogical practice, to develop the personal and relational habits that make authentic democracy possible—a communal form that gives practical meaning to Dewey’s notion of school as “embryonic society”: a utopian space where natality is recognized as a fundamental cultural force, and where the evolutionary possibilities inherent in neoteny are taken as normative. 相似文献

War experiences are known risk factors for post-traumatic stress disorder (PTSD) and other poor psychosocial outcomes. This study aimed to assess the extent to which perpetrating violence (operationalised as intentional and unintentional killing or mutilation) and being a victim of violence (operationalised as being a victim of violence, e. g., witnessing violence, injuries, torture) predict PTSD and other psychosocial outcomes independently in war-affected youth of Northern Uganda. Data on war experiences, PTSD, psychosocial problems, and socio-demographic characteristics were collected from the youth formerly abducted by the Ugandan Lord’s Resistance Army (LRA) at baseline (mean age = 22.39 years; SD = 10.47) and at follow-up (mean age = 23.52 years; SD = 9.28) using self-report questionnaires. On average, the participants spent 3.13 years in captivity (SD = 2.99) and were abducted at 14.14 years of age (SD = 4.21). Regression models were fitted to predict PTSD and psychosocial outcomes from perpetrating violence controlling for being a victim of violence and demographic characteristics. Thirty-seven percent (n = 168) reported killing or being responsible for killing while in rebel captivity. After adjusting for being a victim of violence, perpetrating violence remained a statistically significant predictor of PTSD and poor psychosocial outcomes such as depression, anxiety, somatic complaints, psychotic symptoms, and conduct problems. Among war-affected youth returning from LRA captivity, perpetrating violence may just be as toxic a risk factor for PTSD and other psychosocial outcomes as being a victim of violence. Mental health workers should consider both the effects of being a victim of violence and perpetrating violence in treatment planning. 相似文献

Observers were shown wide-angle pictures of tiles on a ground plane and were asked about the aspect ratios of the tiles. The observers viewed the pictures from a fixed center of projection. Some of the tiles were in a path coming straight toward the observer. In one picture, the path came from the center of the picture, and in two others the path came from the left side of the picture (one from 30° and one from 45° to the left of the center, from the observer’s point of view). The apparent aspect ratios were a function of the elevations of the tiles and the ratios of visual angles of the sides of the tiles. Judgments were identical for all three paths. The local slant of the picture surface was not a significant factor. 相似文献

A central issue in cognitive neuroscience of aging research is pinpointing precise neural mechanisms that determine cognitive
outcome in late adulthood as well as identifying early markers of less successful cognitive aging. One promising biomarker
is beta amyloid (Aβ) deposition. Several new radiotracers have been developed that bind to fibrillar Aβ providing sensitive
estimates of amyloid deposition in various brain regions. Aβ imaging has been primarily used to study patients with Alzheimer’s
Disease (AD) and individuals with Mild Cognitive Impairment (MCI); however, there is now building data on Aβ deposition in
healthy controls that suggest at least 20% and perhaps as much as a third of healthy older adults show significant deposition.
Considerable evidence suggests amyloid deposition precedes declines in cognition and may be the initiator in a cascade of
events that indirectly leads to age-related cognitive decline. We review studies of Aβ deposition imaging in AD, MCI, and
normal adults, its cognitive consequences, and the role of genetic risk and cognitive reserve. 相似文献
