Item APA PsycNET(Charleston Advisor, 2012-07) Bonsteel, Sue; LibraryPsycNET is the online platform from the American Psychological Association offering access to the most comprehensive collection of high-quality information available in psychology, psychiatry, the behavioral sciences, and related fields. Of special note is the variety of media and document types that make up the collections. The seven databases and two e-book collections are integrated into the search interface, allowing for simultaneous or separate searches. The interface Works well for undergraduate and advanced research, providing specialized searching and filtering options. Institutional pricing is reasonable, and several options allow individual access for those with limited needs. [ABSTRACT FROM AUTHOR]Item Comparison of columnar water vapor measurement during the fall 1997 ARM Intensive Observation Period: optical methods(IEEE, 2002-08-06) Schmid, B.; Michalsky, J.; Slater, D.; Barnard, J.; Halthore, R.; Liljegren, J.; Holben, B.; Eck, Thomas; Livingston, J.; Russell, P.; Ingold, T.Optical methods can provide water vapor data from ground-based, airborne or spaceborne measurements of direct or reflected sunlight in spectral channels in and adjacent to water vapor absorption bands. The water-vapor transmittance T/sub w/ derived from these measurements has to be translated into water vapor amounts. Although this relationship is well known qualitatively, it has proven difficult to quantify. Attempts to do so for water-vapor absorption bands in the near-infrared date back to 1912. Recent findings that the H/sub 2/O line intensities in the visible and near infrared portion of the widely used HITRAN-96 database were in error and that H/sub 2/O lines might be missing from the current databases have sparked renewed discussion of the accurate conversion of measured water-vapor transmittance into amounts of water vapor. In the fall of 1997 the Atmospheric Radiation Measurement (ARM) program conducted an Intensive Observation Period (IOP) to study water vapor at its Southern Great Plains (SGP) site. Among a large number of systems such as radiosondes, microwave radiometers, Raman lidars, Global Positioning System, and an infrared spectrometer, four optical instruments were present to measure water vapor. The authors focus on the four optical instruments: the NASA Ames Airborne Tracking Sunphotometer (AATS-6), a CIMEL CE-318 sun/sky photometer, a multi-filter rotating shadowband radiometer (MFRSR), and a rotating shadowband spectroradiometer (RSS).Item Making the Cut: Do Faculty Want to Be Involved in Library Database Cancellations?(SLA Academic Division, 2011) Garczynski, JoyceBecause of the recent economic crisis, a number of academic libraries have faced the possibility of having to cancel database subscriptions. As a major user group of academic libraries, faculty have a history of being involved in collection decisions, but it is unclear to what extent they want to be involved in cancellations. Also, while the library literature outlines a variety of processes that libraries have used to involve faculty in their serials cancellation decisions, very little is written about eliminating databases. This study examines whether the strategies outlined for involving faculty in serials cancellations are applicable to database cancellations. We surveyed tenure-track and full-time faculty members at Towson University to determine their preferences for involvement in database cancellations and to determine if those preferences are a function of knowledge about the library and/or discipline of study.Item Millennial Students' Mental Models of Information Retrieval(2009-10) Holman, Lucy; Kaplan, Nancy; Summers, Kathryn; Daniel, Evelyn; University of Baltimore. School of Information Arts and Technologies.; University of Baltimore. Doctor of Communications Design.This qualitative study examines first-year college students’ online search habits in order to identify patterns in millennials’ mental models of information retrieval. The study employed a combination of modified contextual inquiry and concept mapping methodologies to elicit students’ mental models. The researcher confirmed previously observed millennial behavior including preference for searching rather than browsing and hypertext reading. The study found three basic types of mental models; those with a network view conducted more searches overall and more complex (Boolean and topic + focus) searches. However, none of the participants demonstrated strong mental models that increased their effectiveness in searching.
