This study was conducted to investigate if there are any predictive relationships between scores of the Graduate Record Examination (GRE) and graduate grade point average (GGPA), and undergraduate grade point average (UGPA) and GGPA. The data were collected from all graduates from the Master's program in Criminal Justice at a medium-sized Southern university from 1989 to 1999 (N = 94). The results indicated that UGPA and GRE scores explain about 40% of the variance in GGPAs. It is concluded that all three GRE subscales should be considered in the graduate admissions process in criminal justice programs.  相似文献

There is limited data on the implementation of Comprehensive Sexuality Education in Nigerian schools. This study explored In-School adolescents' perspectives on the implementation and utility of the Family Life and HIV/AIDS Education Curriculum, using questionnaires and focus group discussions. Findings reveal that sexuality education in schools is mostly moralistic and cognitive in emphasis, with limited adaptation of interactive methodologies. Inadequate teacher training, teachers' sexual double standards, and limiting curriculum to junior classes were identified as major setbacks. Curriculum expansion, Comprehensive School health programming, continuous teacher training and ensuring that teachers are held accountable for their behaviors are recommended.  相似文献

This article describes the process of transforming the Arkansas Periodical Index, which began as a card file index in the University of Arkansas (U. of A.) Libraries, to an online database. As in many other states, in-house indexes were compiled to cover local history journals and subject-related magazines. A variety of software now exists to mount locally created databases, one option being the choice to use the same turnkey software that runs the library's online catalog. We began by converting our card files to a local Inmagic DB/Textworks database. The U. of A. received the 1991 Gale Research Award for Excellence in Reference and Adult Library Services for that design. We later mapped the database structure to MARC fields and mounted it as a Web-accessible database through our library OPAC vendor, Innovative Interfaces, Inc. (III). The authors begin with a brief history of periodical indexing, the reasons for choosing MARC formatting, and the field mapping required. The article explains the development of the database to include other publication formats, such as material from biographical compendiums, newspaper indexing, and university publications. The mapping incorporates indexing several publication formats in the same database. It also provides fields for linking citations back to the OPAC records, where users may find call numbers for journals or books, be connected to the full text of articles when available, or to an association's own website when applicable. We address some of the concerns for libraries in developing indexing projects. The article offers a mapping table of migrated fields that can be used by others wanting to encourage the rediscovery of local print periodicals and to expand access to the various materials otherwise buried in the library's special collections. The Arkansas Publications Index was released in April 2005 and is available free at http://arkindex.uark.edu/.  相似文献

Whether or not uniform titles serve any useful purpose has been debated almost since their implementation in 1981 with the adoption of AACR2 (Anglo-American Cataloguing Rules. Second Edihon). The problems posed by a separate bibliographic record for each physical manifestation of the same intellectual work (e.g., original, reprint, microfilm) apply to some extent to all categories of material, but present special problems for union lists of serials. This article discusses these two problem areas of serials cataloging. A proposed solution to the multiple versions dilemma is also briefly discussed.  相似文献

The effect of morphine preexposure on place conditioning with morphine was investigated. In the first experiment, five injections of 10 mg/kg morphine were administered to rats prior to place conditioning or taste-aversion training with morphine. Although this number of preexposures retarded taste-aversion learning, there was no effect on place conditioning. In subsequent experiments we investigated the role of context blocking in UCS preexposure in place conditioning. In one experiment, preexposure to five morphine injections prior to place conditioning resulted in a reduced place preference, compared with preexposure and place conditioning in different contexts. However, the overall detrimental effect of morphine preexposure was questionable, because the rats that were preexposed were only marginally different from those that were not preexposed. In a final experiment we examined the effect of a context change from preexposure to place conditioning with 15 preexposures and demonstrated a detrimental effect of preexposure on place conditioning that was context specific. These results support a role of classical conditioning in place-preference conditioning with morphine.  相似文献
