Library-user interface: A simulation of the circulation subsystem

The loan policy of a university library can have a significant effect on the ability of library users to find the particular books that they are seeking. This paper focuses on the library-user interface by relating two measures of user satisfaction, book availability and the delay associated with recalls, to the loan policy of the library. This relation is established by computer simulation techniques. This paper synthesizes the results of two studies conducted at the Sears Library at Case Western Reserve University. The results of these studies confirm that the model can accurately predict two measures of user satisfaction as a function of the load policy of a library. Thus this technique can be used to evaluate alternative loan policies in terms of their impact on user satisfaction.     

Identifying strategic management information systems planning parameters using case studies

The management information systems (MIS) literature reveals a list of parameters essential for the successful implementation of an IS planning process. Some studies stress the importance of integrating the corporate objectives of a firm into the IS planning process. Other studies discuss the importance of performing an analysis of competitors, or determining the stage of maturity a firm has reached, or the framework used for setting information technology investment priorities. Yet others state that the choice of methodology that will be utilized to develop the IS plan will be crucial to the success of that plan. The objective of this paper is to develop a holistic conceptual model that combines the above parameters into a framework that fully integrates the corporate objectives of a firm into every aspect of the planning process. Three large multi-national courier companies with regional headquarters in Singapore were studied over an eight-month period while undergoing an extensive MIS planning process. Based on these studies, a model based on general systems theory that views the IS planning process in a holistic framework firmly rooted in the view that a firm's corporate objectives must drive the entire process.     

Peers and Spheres of Influence: Situating Rob Kling

In this article we employ a number of bibliometric techniques to capture Rob Kling's intellectual impact and influences over the course of his varied career. We analyze his many publications in terms of type, topic, impact, and rate of co-authorship. We provide a detailed deconstruction of his citation identity (all those scholars whom he cited) and also his citation image makers (all those scholars who cited his work). In addition, we analyze acknowledgment data to gain deeper insights into the sociocognitive networks that sustained, and were sustained by Kling throughout his career.

Trajectories of early childhood family instability and the development of externalizing behaviors from middle childhood to adolescence: A prospective study of at-risk families

This study examined associations between trajectories of family instability across early childhood and trajectories of externalizing behaviors from middle childhood to adolescence. Growth mixture models were fit to annual caregiver reports of instability from child ages 2–5 (N = 731; 49% girls, 50% White). A curve of factors model was fit to externalizing behaviors from child ages 7.5–14. Chronic, elevated instability across early childhood predicted elevated externalizing behaviors from middle childhood to adolescence. Data collection spanned from 2002 to 2017. Increasing or declining levels of instability predicted elevated externalizing behaviors in middle to late childhood, but not in adolescence. Caregiver depressive symptoms mediated the association between instability and the externalizing behavior intercept. Intervening on chronic instability may reduce child externalizing problems.     

CLASSIFICATION ACCURACY OF ORAL READING FLUENCY AND MAZE IN PREDICTING PERFORMANCE ON LARGE‐SCALE READING ASSESSMENTS

The purpose of this study was to examine whether using a multiple‐measure framework yielded better classification accuracy than oral reading fluency (ORF) or maze alone in predicting pass/fail rates for middle‐school students on a large‐scale reading assessment. Participants were 178 students in Grades 7 and 8 from a Midwestern school district. The multiple‐measure framework yielded classification accuracy rates that were either similar to, or better than, the individual predictors. Specificity was improved using a combined measure of ORF and maze versus individual predictors alone. Educational implications for identifying students in need of reading intervention are discussed.
