"Ask A Librarian": the experiences of four hospital libraries

The librarians at four hospital libraries describe the electronic reference service, "Ask A Librarian," offered at their institutions. The hospitals are vastly different in size and in number of library staff, and offer the "Ask A Librarian" service to different clientele. The article illustrates that both large hospitals with a large library staff and small hospitals with a solo librarian and some volunteers can offer this type of service.     

Interactive Influences of Perceived Social Contexts on the Reading Achievement of Urban Middle Schoolers with Learning Disabilities

This study examined the effects of social influences in the lives of an ethnically diverse sample of fifth through eighth grade students with and without learning disabilities (LD) using survey data and academic achievement scores collected in 19 Chicago public schools from 1993–1997. Similarities and differences in student perceptions of school, family, and peer group contexts were examined. In addition, longitudinal data were analyzed using hierarchical linear modeling (HLM) to identify contextual influences on changes in student reading achievement over time. Comparisons of student responses confirm and extend existing findings in the literature concerning the perceptions of students with LD of their social environments. In particular, having a learning disability was associated with consistent, mostly negative, effects on social relations across the contexts of students’ lives, regardless of gender, race, grade, and socioeconomic status. In addition, student perceptions of their friendship groups were found to have small, but significant, effects on their growth in reading achievement over the course of middle school. While students with and without LD had somewhat different views of their social contexts, the processes working within these environments appeared to affect their reading achievement in similar ways. The results suggest that careful attention should be paid to the social contexts of students’ lives when planning academic interventions.     

Multiple Copies of Bestsellers in Public Libraries: How Much Is Enough?

How do public libraries develop their collections of high-demand materials for the “I want it now” generation? Ten public libraries’ holdings of fiction and nonfiction bestseller titles were observed over a four-week period. The number of copies rose fairly consistently, with the five fiction titles having roughly about twice the number of copies as the five nonfiction titles. The ratio of holds to copies averaged 2.7:1 and ranged from 0.8:1 to 6.5:1. Demand for e-books was consistently higher than the number of copies available, averaging more than 4:1 across all libraries.     

Mobility and wage equilibration in the educator labor market

Using longitudinal data, this article examines mobility and wage equilibration patterns for instructional personnel for kindergarten through the twelfth grade. The study concludes that (1) contrary to popular belief, educators are at least as responsive as other workers to interoccupational wage differences in deciding to change occupations; (2) educators paid above (below) the wage they could expect in the economy at large experience less (greater) than average wage growth; (3) educators are responsive to wage differentials within teaching in deciding to change districts but not as strongly responsive as to wage differentials between teaching and other occupations; and (4) educators paid above (below) the average wage for educators with similar qualifications experience less (greater) than average wage growth from one school year to the next.“Frustrated teachers stew over working conditions, but most don't quit.”
