The free-play behavior of young hearing impaired children in integrated and segregated settings was compared using a multielement baseline design. Two children, aged 3 and 5, were observed using momentary time sampling of their play as they alternated from one setting to the other. Data were collected in ech setting for various categories of play behavior. The categories were derived from the classic play categories of Parten and Smilansky. Results indicate that the children engaged in more socially advanced play in the integrated setting. 相似文献

Two mechanisms have been suggested to explain stretching-induced maximum force depression: a mechanical alteration in the stretched muscle and an impairment of neural activation. Electrical stimulation allows standardization of the level of muscle activation without being limited by neural control. The aim of this study was to evaluate the stretching-induced changes in the electrical and mechanical properties of muscle during electrically elicited contractions. Twelve participants (age 22 +/- 1 years; body mass 75 +/- 2 kg; stature 1.79 +/- 0.02 m; mean +/- standard error) underwent six electrical stimulations of the medial gastrocnemius muscle before and after stretching. During the contractions, surface electromyogram (EMG) and mechanomyogram (MMG) were recorded simultaneously together with force. After stretching we found: (i) no differences in EMG parameters; (ii) MMG amplitude decreased by 4 +/- 1% (P < 0.05); and (iii) the peak force, the peak rate of force development, and the acceleration peak of force development decreased by 12 +/- 3%, 14 +/- 1%, and 24 +/- 5%, respectively (P < 0.05). In conclusion, acute passive stretching did not change EMG properties but altered the mechanical characteristics of the contracting muscle. Indeed, muscle force-generating capacity and stiffness of the muscle-tendon unit were significantly impaired. 相似文献

This article examines how undergraduate instructors of pre-service educators can address complex issues of sexuality and sexual orientation within the classroom. First, we explain our own backgrounds and positionalities to provide a context for our ensuing ideas and discussions. Second, by reviewing the literature on homophobic bullying, we outline why it is imperative that preservice teachers understand and mobilize around issues of gay, lesbian, bisexual, transgender, queer/questioning, intersex rights. Third, we offer suggestions as to how to relate to undergraduate students when talking about sexuality and sexual orientation. We propose that using popular culture is an effective and engaging way of connecting to preservice teachers who have not previously had to confront their own homophobia and heterosexism. We suggest that using popular films or TV shows, such as Ugly Betty, has the potential to open up space for dialogue and critical engagement with issues such as explicit or implicit homophobia. We believe that critical media literacy skills are necessary tools for young people who are constantly bombarded with oftentimes stereotypical images and personifications of GLBTQI people within the mainstream media. Consequently, although we propose that popular culture be used as an educative space within the undergraduate classroom, it must be used both carefully and critically. Finally, we discuss why it is imperative that undergraduate professors address these issues within the classroom by referencing recent tragedies that are directly connected to homophobic bullying. 相似文献

The migration from print books to ebooks is more than a change of format; it is also the first step in an ongoing process,
whose final outcome is hard to predict. Ebooks are likely to lead to a restructuring of the industry by enabling cross-border
commerce. This in turn is likely to lead to difficult disputes over territorial rights. It appears probable that these disputes
will be resolved by an assertion of the dominance of the American market and the publishers that already serve it well, as
authors are likely to place their rights with practitioners in the largest markets. This in turn will lead to the acquisition
of many smaller “national” publishers, which cannot compete on a world stage with truly global publishers. But rather than
simply becoming sources of editorial product for American-based global marketing machines, smaller publishers operating in
different regions will respond through innovation, both in product design (attempting to do electronically what cannot be
done in print) and in developing new marketing plans that the giant publishers would be indisposed to pursue. 相似文献

This article is an autoethnographic account of how I negotiated intersectional identities as a Latina, mother, and professor, mentoring students of color. Specifically, I examine the ways mothering shaped my relationships with the students I mentored. I engaged in “othermothering” and utilized “pedagogies of the home” by creating reciprocal relationships of caring and nurturing. Utilizing critical race theory (CRT) and testimonio, I argue that my identity as a mother of color successfully negotiating the tenure track impacted the ways in which I mentor(ed) students of color. 相似文献

Two preregistered experiments with 2,733 U.S. high school students (age range = 13–19 years) compared the impact of different messages on adolescents’ motivation to control social media use (SMU). A traditional message emphasized the benefits of avoiding SMU, whereas a values-alignment message framed controlling SMU as being consistent with autonomy and social justice. Compared to no message or a traditional message, in both studies, a values-alignment message led to greater motivation to control SMU immediately afterward, and in Study 2, awareness of “addictive” social media designs 3 months later. As hypothesized, values-alignment messaging was more motivating for girls than boys. Results offer preliminary support for leveraging adolescents’ drives for autonomy and social justice to motivate self-regulation of SMU. 相似文献

In this article, a group of nontraditional and/or doctoral students of color and our advisor discuss how the advisor-advisee mentoring relationship has positively affected our experiences within academia. The mentoring relationship, cultivated within a group mentoring model, was integral to our acclimation of the hidden culture of our doctoral programs. We elaborate on the history and mentoring model of the group of which we are a part, and follow with a review of the literature on mentoring practices and a discussion of methodology. Finally, through autoethnographic vignettes, each author discusses his/her experience as a non-traditional and/or student of color and how our relationship with the group has provided us with the logistical, emotional, and psychological support needed to progress in and complete our programs. 相似文献

This paper provides an overview of the knowledge management systems (KMSs) adopted by small and medium enterprises (SMEs). KMSs are divided into two categories: knowledge management tools (KM-Tools) and knowledge management practices (KM-Practices). On the basis of the analysis of the literature, two research questions (RQs) were identified and addressed through semi-structured interviews carried out in a sample of 35 SMEs operating in high-tech industries. The first RQ concerns the degree of adoption of KMSs by SMEs. The second RQ regards the relationship between KM-Tools and KM-Practices. As far as the degree of adoption of KMSs, the paper highlights that SMEs are not a homogeneous world but there are a variety of approaches and behaviours. As far as the relationship between the degree of adoption of KM-Tools and KM-Practices, the paper identifies three groups of SMEs that seem to point out the stages of the process of adoption of KMSs: Introduction, SMEs that deal with the process of knowledge management exploiting practices and tools that are already known; Growth, SMEs that adopt specialist practices of knowledge management acquiring new organisational and managerial competence in the field of knowledge management; Maturity, SMEs that invest in new technology and that acquire new technological competence in the field of knowledge management. This categorisation paves the way for further theoretical and practical implications for both managers and policy makers. 相似文献

Several composite indexes grouping several variables into a single figure have been proposed for measuring the digital divide. In this article, the authors analyze shortcomings of extant indexes. Using multivariate analysis tools, they show that in the definition of composite indexes it is possible to individuate a limited set of more influencing and significant variables. This finding suggests the possibility of replacing some redundant variables with other dimensions that include other aspects of the digital divide that are not considered in extant measures. 相似文献
