Combining new technologies for effective collection development: a bibliometric study using CD-ROM and a database management program.

Librarians have used bibliometrics for many years to assess collections and to provide data for making selection and deselection decisions. With the advent of new technology--specifically, CD-ROM databases and reprint file database management programs--new cost-effective procedures can be developed. This paper describes a recent multidisciplinary study conducted by two library faculty members and one allied health faculty member to test a bibliometric method that used the MEDLINE and CINAHL databases on CD-ROM and the Papyrus database management program to produce a new collection development methodology.     

Comparing action gestures and classifier verbs of motion: evidence from Australian Sign Language, Taiwan Sign Language, and nonsigners' gestures without speech

Recent research into signed languages indicates that signs may share some properties with gesture, especially in the use of space in classifier constructions. A prediction of this proposal is that there will be similarities in the representation of motion events by sign-naive gesturers and by native signers of unrelated signed languages. This prediction is tested for deaf native signers of Australian Sign Language (Auslan), deaf signers of Taiwan Sign Language (TSL), and hearing nonsigners using the Verbs of Motion Production task from the Test Battery for American Sign Language (ASL) Morphology and Syntax. Results indicate that differences between the responses of nonsigners, Auslan signers, and TSL signers and the expected ASL responses are greatest with handshape units; movement and location units appear to be very similar. Although not definitive, these data are consistent with the claim that classifier constructions are blends of linguistic and gestural elements.     

An experiential system for learning probability: Stat Lady description and evaluation

This paper describes a computer-based instructional system called Stat Lady, and reports the results of an evaluation study that tested the efficacy of learning probability from this program in relation to a traditional Lecture and a no-treatment Control group. Results showed that both treatment groups learned significantly more than the Control group, yet there was no difference between the two treatment groups in outcome performance after three hours of instruction. This was viewed as encouraging because: (a) due to sampling error, students assigned to the Stat Lady condition were at a disadvantage, scoring about 20 points less on the quantitative SAT measure compared to the Lecture group, and about 25 points less than the Control group, (b) the lecture constituted a more familiar learning environment for these subjects, and (c) the professor administering the Lecture had more than 20 years experience teaching this subject matter, while this was Stat Lady's first teaching assignment. We also found a significant aptitude-treatment interaction where high-aptitude subjects learned more from Stat Lady than from the Lecture environment, but for low-aptitude subjects, there was no difference in learning outcome by condition. Implications of these findings will be discussed in relation to future computer-based instructional research.

     

Mapping the core journals of the physical therapy literature

Objectives:

The purpose of this study was to identify (1) core journals in the literature of physical therapy, (2) currency of references cited in that literature, and (3) online databases providing the highest coverage rate of core journals.

Method:

Data for each cited reference in each article of four source journals for three years were recorded, including type of literature, year of publication, and journal title. The journal titles were ranked in descending order according to the frequency of citations and divided into three zones using Bradford''s Law of Scattering. Four databases were analyzed for coverage rates of articles published in the Zone 1 and Zone 2 journals in 2007.

Results:

Journal articles were the most frequently cited type of literature, with sixteen journals supplying one-third of the cited journal references. Physical Therapy was the most commonly cited title. There were more cited articles published from 2000 to 2007 than in any previous full decade. Of the databases analyzed, CINAHL provided the highest coverage rate for Zone 1 2007 publications.

Conclusions:

Results were similar to a previous study, except for changes in the order of Zone 1 journals. Results can help physical therapists and librarians determine important journals in this discipline.

Highlights

• More cited references were published in the last eight years studied than in any previous full decade.
• Physical Therapy, Archives of Physical Medicine and Rehabilitation (APMR), and Spine were the most frequently cited titles. Previous studies found APMR to be the most cited journal.
• CINAHL provided the highest coverage rate for the most commonly cited titles, with MEDLINE and EMBASE providing the best coverage for the next group of titles.

Implications

• Health sciences librarians and clinicians can use these results to identify important journals for developing collections and determining the need for access to back issues of journals.
• Multiple databases are needed for comprehensive coverage of the physical therapy discipline
