Demarcating Medicine's Boundaries: Constituting and Categorizing in the Journals of the American Medical Association

This article examines professional boundary work in a set of medical journal theme issues about complementary and alternative medicine (CAM). Whereas these journals claim as their collective goal to bridge and blur boundaries between mainstream and alternative medicine, this article identifies and describes two chief rhetorical strategies through which the journals instead bolster and even expand those boundaries. These two strategies, constituting and categorizing, appear central to the demarcation of biomedical boundaries vis-à-vis CAM.     

The enrichment triad model for the very young gifted

The article describes why the Enrichment Triad Model needs to be adapted for a preschool/primary setting and provides suggestions for educators on how to do this. A real‐life example of a five‐year‐old who successfully completed a Type III project is presented. The role of the teacher in understanding how a young child's differences in social, physical, academic, and emotional development can influence appropriate programming is emphasized.     

An Experimental Test of Student Verbal Reports and Teacher Evaluations as a Source of Validity Evidence for Test Development

The Standards for Educational and Psychological Testing indicate that test instructions, and by extension item objectives, presented to examinees should be sufficiently clear and detailed to help ensure that they respond as developers intend them to respond (Standard 3.20; AERA, APA, & NCME, 1999 American Educational Research Association (AERA), American Psychological Association (APA), National Council on Measurement in Education (NCME). 1999. Standards for educational and psychological testing, Washington, DC: Author.  [Google Scholar]). The present study investigates the use of verbal reports, one of many sources of evidence for validity arguments, as a way to evaluate the content clarity of 30 items from a large-scale science assessment. Student reports were used to edit items and create a student-modified test form. Evaluations from expert preservice teachers were used to edit the items and create an expert-modified test form. Both experimental forms, along with the original set of 30 items, were then randomly assigned to a sample of 264 examinees. Hierarchical regression analyses indicated that examinee performance on the student-modified and expert-modified forms was similar relative to performance on the original test items. Item statistics indicated that student-modified test items were equally difficult and discriminating as expert-modified test items. The implications of using student and teacher evaluations are discussed for informing test development.     

Identifying swimmers as water-polo or swim team-mates from visual displays of less than one second

Abstract

Opportunities for ball passing in water-polo may be brief and the decision to pass only informed by minimal visual input. Since researchers using point light displays have shown that the walking or running gait of familiars can be identified, water-polo players may have the ability to recognize team-mates from their swimming gait. To test this hypothesis, members of a water-polo team and a competition swim team viewed two randomized sets of video clips, each less than one second long, of swimmers from both teams sprinting freestyle past a fixed camera. The arm stroke clip sequence showed only the upper body, and the kick sequence showed only the lower body. After viewing each video clip, observers rated their level of certainty as to whether the swimmer presented was a team-mate or not. Discrimination was significantly above chance in both groups. Water-polo players were better able to identify team-mates from their kick, whereas swimmers were better able to do so by viewing arm stroke. Our results suggest that, as with walking and running gait, small amounts of visual information about swimmers can be used for recognition, and so raise the possibility that specific training may be able to improve team-mate classification in water-polo, particularly in newly formed teams.     

Implementing Twitter in a health sciences library

The NYU Health Sciences Libraries created an account on Twitter, a microblogging service, as a new outreach tool marketed to students, faculty, and staff. The team used Twitter to promote resources, events, and news. Twitter is a part of a pipeline of information that also includes the library's Web site and Facebook. Although it is difficult to measure the effectiveness of a social networking tool, the overhead of using Twitter is so low that it merits consideration.     

At home with disability: one family’s three generations narrate autism

We examined the lived experiences of a Cypriot family with a young child with autism. Semi‐structured interviews with parents, siblings, and extended family members across three generations and observations of the family’s daily activities were the primary data‐generating methods. Critical events related to the disability diagnosis, the mother’s decision to undertake a significant role in the child’s education following negative interactions with professionals, and the family’s daily accommodations to the child’s needs emerged in narratives of multiple participants. Family narratives reflect the polyphony of experiences and responses shared by participants. The study illuminates the complexities of this experience and offers opportunities to rethink the interplay of disability, family, and culture in the context of research and practice.
