Students with disabilities typically experience academic, social, and behavioural challenges in school. Some of these students also often experience anxiety and stress associated with school situations and events. Wearable technologies are an emerging innovation in the United States that can support students with disabilities during stressful academic or social situations. This article discusses issues associated with wearables, offers questions to consider when considering a wearable device for a student, and describes several wearable technologies for students with disabilities. 相似文献

One of the most widely used solutions to fix and preserve organic tissues is formaldehyde, despite reservations regarding its toxicity and the fact that formaldehyde-embalmed bodies lose their original characteristics. Anatomy laboratories have been replacing formaldehyde with solutions that retain the characteristics of fresh tissue. For this purpose, alternative solutions with a very low concentration of formaldehyde or without any formaldehyde have been analyzed. The objective of this study was to compare biometry, coloration, haptic properties, and bacterial load on animal specimens (pig kidneys) embalmed with formaldehyde, and with Chilean Conservative Fixative Solution with and without formaldehyde (formaldehyde chCFS and formaldehyde-free chCFS). Also, the perception of health and biological science students toward specimens treated with different solutions was assessed. The results indicated that there were no significant differences in specimens’ retraction, or bacterial load. Students showed a preference for organs embalmed in formaldehyde chCFS and formaldehyde-free chCFS; indicating that with these treatments they could better visualize structures and that the prosections had greater flexibility and the colors were more similar to those of fresh tissue. Additionally, students recommended the material embalmed in formaldehyde chCFS and formaldehyde-free chCFS for anatomy learning. In contrast, students indicated that formaldehyde-fixation negatively affected their practical experience. In conclusion, embalming with formaldehyde chCFS or formaldehyde-free chCFS provides an advantageous practical experience over the use of formaldehyde and may be an alternative to replace the use of formaldehyde in anatomy laboratories. 相似文献

William James (1919) characterises hypotheses as either live or dead. A hypothesis is live when it is taken into account as a ‘real possibility’. We follow James’ suggestion to not attribute intrinsic properties to hypotheses, but rather investigate how they came into being and look at the effects they generate. Expectations of digital technologies are a topic of vivid debate in the insurance industry. Before these expectations can become ‘live’, they have, in the first place, to be generated by market devices. We investigate how the reinsurance blogpost platform Open Minds functions as an ‘expectation generation device’ on the future of insurance markets. Combining Beckert’s work on the role of fictional expectations with the pragmatist turn in sociology of markets, we propose to study ‘expectation generation devices’, provoking expectations on economic markets. In our empirical analysis, we demonstrate the explicit fictional character of the Open Minds contributions, and analyse how a contained space of openness is generated to provoke expectations. We demonstrate how Open Minds can become live through circulation to other expectation generation sites in the insurance industry and beyond. We conclude by reflecting on the importance of expectation generation devices as a particular type of market devices. 相似文献

Whether and to what extent kindergarten children's executive functions (EF) constitute promising targets of early intervention is currently unclear. This study examined whether kindergarten children's EF predicted their second-grade academic achievement and behavior. This was done using (a) a longitudinal and nationally representative sample (N = 8,920, Mage = 97.6 months), (b) multiple measures of EF, academic achievement, and behavior, and (c) extensive statistical control including for domain-specific and domain-general lagged dependent variables. All three measures of EF—working memory, cognitive flexibility, and inhibitory control—positively and significantly predicted reading, mathematics, and science achievement. In addition, inhibitory control negatively predicted both externalizing and internalizing problem behaviors. Children's EF constitute promising targets of experimentally evaluated interventions for increasing academic and behavioral functioning. 相似文献

ABSTRACT Game developers potentially convey socio-cultural values about gender through design choices. This study interpreted the designs of 11 purposively selected female game characters, developed by studios located in the United States and Japan, through the lens of ambivalent sexism. This social psychological theory posits that sexism consists of hostile and benevolent attitudes about women. Two themes emerged across characterizations: bodies as objects, bodies as weapons and (in)dependence. Both consisted of empowering qualities paired with problematic beliefs about women. This analysis contributes to interdisciplinary literature by using an empirical perspective to interpret gender representations in video games. 相似文献

The focus of this paper is on a group of pupils with reading and writing difficulties who have been participating in an intervention study using assistive technology. That intervention study contained supervised training sessions with reading and writing tasks using an iPad with special supportive applications. The current study is a qualitative investigation of whether there has been any transfer from the intervention, to the pupils’ everyday school activities. Interviews with pupils and their teachers and observations during classroom lectures have been used to collect data. The results show that the pupils were positive to the assistive technology (the applications on the iPads), they found the apps easy to learn how to use and they appreciated the benefits they could give. Even so, only a few of the pupils had found use for and continued to use the tools after the intervention period finished. Possible reasons are that when the novelty wore off, students reverted to their usual study habits and that older students with many teachers and different classrooms were less able to adapt to using the apps. To improve transfer, it is suggested to introduce assistive technology earlier to students, in the younger grades, before study habits have been formed and to inform teachers about the use of AT in the classroom, including what is available and how it can benefit students. 相似文献

The object of the study was to determine the major needs of students at the University of the Western Cape (U.W.C.). A second aim was to determine how students view the nature of the Centre for Student Counselling (C.S.C.). No needs assessments have previously been done on the U.W.C. campus and this lack of knowledge pertaining to the needs of students could have meant a misdirected focus in terms of the provision of counselling services.The study was done with a representative sample of students from all the year groups. Students were asked to fill in a questionnaire consisting of two parts. In Part I a student had to indicate how prevalent he thought a particular set of problems were on campus. In Part II he had to indicate whether he would have referred a friend to the C.S.C. with a particular problem.The results had indicated that problems were predominantly seen to be in the vocational-academic area and that students were more willing to refer fellow students to the C.S.C. with the above-mentioned problems than with problems of a more personal-social nature. Although the results were to be expected, it was emphasized that vocational-academic problems are often used as a smoke-screen and that counsellors should also be aware of underlying social-emotional problems. 相似文献
