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.     

The Communication Privacy Management of Adopted Individuals in Their Social Networks: Disclosure Decisions in Light of the Discourse of Biological Normativity

Although adoptees are often stigmatized for their nonnormative identity, adopted individuals must communicate with nonfamily members to integrate their adoptive identity into their definition of self. In the current study, adult adoptees (n = 25) were interviewed about their processes for disclosing their adoptive status in their social networks. Drawing upon communication privacy management (CPM) theory, inductive analyses demonstrated that adoptees created motivational and contextual criteria to enact privacy rules surrounding adoption. Adoptees maintained privacy to avoid messages of “difference,” insensitive comments, imperviousness, and negative opinions about adoption. Adoptees disclosed about their adoption to build relational closeness and to educate/advocate for adoption. These privacy decisions were undergirded by the societal assumption that families are biologically linked or the discourse of biological normativity (Suter et al., 2014).     

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.
