The usefulness of monographic proceedings

Librarians have often questioned the usefulness of the proceedings of biomedical meetings. Because articles in proceedings are similar to journal articles, the usefulness of the two were compared. Thirty-two monographic cardiovascular proceedings were compared to thirty-five cardiovascular journals, all published in 1978. Citations to the articles in these samples were counted for the years 1978, 1979, and 1980, and an impact factor was calculated for each proceedings and journal. The mean impact factor of the journals (3.86) was significantly higher than the mean impact factor of the proceedings (0.98, p less than .001). A short delay in publication of a proceedings was not associated with a higher impact factor. There were no differences in impact factors between U.S. and non-U.S. meeting sites. Proceedings of "hot" topics were not associated with higher impact factors, and multiple-index coverage of proceedings was only weakly associated (tau = 0.27) with higher impact factors. While camera-ready proceedings had a significantly higher mean impact factor (2.37) than typeset proceedings (0.66, p less than .02), selection based on printing method is not recommended. It is concluded that most libraries can safely forego the purchase of monographic proceedings. If a library needs monographic proceedings, it should purchase only those recommended by subject specialists.     

Development of object permanence in the New Zealand parakeet (Cyanoramphus auriceps)

Eleven young kakarikis (Cyanoramphus auriceps) were tested on 15 object-permanence tasks in a standardized scale that has been used to assess the development of human infants, some nonhuman primates, and other mammals. The birds successfully completed all tasks in this scale, and many aspects of their testing were similar to human results, such as evidencing the A-not-B error. However, the birds differed slightly but significantly from human subjects in that some of the “invisible displacements” of the later tasks were performed before the earlier visible displacement tasks. These results may relate to common ecological activities of this species. Six of the birds were parent-raised; 5 were hand-raised. The hand-raised birds achieved criteria more quickly than did the parent-raised birds possibly because the former were more accustomed to the investigator and less distractible in the test situation.

Our words,our story: a textual analysis of articles published in the Bulletin of the Medical Library Association/Journal of the Medical Library Association from 1961 to 2010

Purpose:

This lecture explores changes in the medical library profession over the last fifty years, as revealed by individual word usage in a body of literature.

Methods:

I downloaded articles published in the Bulletin of the Medical Library Association and Journal of the Medical Library Association between 1961 and 2000 to create an electronic corpus and tracked annual frequency of individual word usage. I used frequency sparklines of words, matching one of four archetypal shapes (level, rise, fall, and rise-and-fall) to identify significant words.

Results:

Most significant words fell into the categories of environment, management, technology, and research. Based on word usage changes, the following trends are revealed: Compared to 1961, today''s medical librarians are more concerned with digital information, not physical packages. We prefer information to be evidence-based. We focus more on health than medicine. We are reaching out to new constituents, sometimes leaving our building to do so. Teaching has become important for us. We run our libraries more like businesses, using constantly changing technology. We are publishing more research articles.

Conclusions:

Although these words were chosen by individual authors to tell their particular stories, in the aggregate, our words reveal our story of change in our profession.The Janet Doe Lecture on the history or philosophy of medical librarianship: I will warn you right now that you will get very little philosophy out of me today, for two reasons. First, my predecessor T. Scott Plutchak, AHIP, was a philosophy major, and I knew that a zoology major like myself could not compete with that. Second, “philosophy” in many Janet Doe lectures is actually a strong personal viewpoint of medical librarianship—what it is or what it should be. I do collection development, where things change so much and so rapidly that I have not had time to develop a strong viewpoint like many of my Doe predecessors. Like most of my collection development colleagues, I''m just trying to survive day to day. That tends to create a very pragmatic attitude. If I believe in anything strongly, it is that I believe I''ll have another cookie.Without philosophy, I am left with history. And here I will echo the complaint of many Doe lecturers by stating that I have a severe lack of historical research skills. I became painfully aware of this lack as I read previous Doe Lectures, such as David Kronick''s 1980 lecture 1. Kronick was a true scholar, with a doctorate in librarianship. We honor him to this day with the Medical Library Association''s (MLA''s) David A. Kronick Traveling Fellowship. In his Doe Lecture, Kronick quoted H. Curtis Wright''s “The Oral Antecedents of Greek Librarianship,” Francis Bacon, and the fifteenth-century Abbot Johannes Trimethius. In contrast, later in this speech, I will quote the Talking Heads.While I am totally unqualified for traditional historical research, that still leaves informal, or personal, history. Although I am old enough to be in my anecdotage, I just do not have many interesting stories to tell. And as Thomas Basler, FMLA, told us in his 2008 Doe Lecture, there are no more giants. While I met some of those giants, I did not know them, and I certainly do not have any stories to tell about them. I suppose I could tell stories about some of the taller than average individuals I have met in my career, but that does not sound very exciting.     

Object permanence in four species of psittacine birds: An African Grey parrot (Psittacus erithacus), an Illiger mini macaw (Ara maracana), a parakeet (Melopsittacus undulatus), and a cockatiel (Nymphicus hollandicus)

Four psittacids—an African Grey parrot, an Illiger macaw, a cockatiel, and a parakeet—were tested on object-permanence tasks that are commonly used to assess levels of understanding in human infants during their first 2 years. These birds showed Stage 6 competence, demonstrating that object permanence is not limited to mammals. The results for these birds were comparable to those of an African Grey parrot that had been trained in interspecies communication prior to object-permanence testing. Our findings thus suggest that although language-like behavior provides a communication channel that facilitates testing, such language training is unlikely to affect the outcome of the tests.     

Trends in hospital librarianship and hospital library services: 1989 to 2006

Objective:

The research studied the status of hospital librarians and library services to better inform the Medical Library Association''s advocacy activities.

Methods:

The Vital Pathways Survey Subcommittee of the Task Force on Vital Pathways for Hospital Librarians distributed a web-based survey to hospital librarians and academic health sciences library directors. The survey results were compared to data collected in a 1989 survey of hospital libraries by the American Hospital Association in order to identify any trends in hospital libraries, roles of librarians, and library services. A web-based hospital library report form based on the survey questions was also developed to more quickly identify changes in the status of hospital libraries on an ongoing basis.

Results:

The greatest change in library services between 1989 and 2005/06 was in the area of access to information, with 40% more of the respondents providing access to commercial online services, 100% more providing access to Internet resources, and 28% more providing training in database searching and use of information resources. Twenty-nine percent (n = 587) of the 2005/06 respondents reported a decrease in staff over the last 5 years.

Conclusions:

Survey data support reported trends of consolidation of hospitals and hospital libraries and additions of new services. These services have likely required librarians to acquire new skills. It is hoped that future surveys will be undertaken to continue to study these trends.

Highlights

• Data support reported trends in the decrease in the number of hospitals and hospital libraries.
• About 44.0% of hospitals had some level of onsite library service in 1989, compared with between 33.5% and 29.1% of hospitals in 2005/06.
• More electronic services and resources, such as Internet access and online materials, are being offered by hospital libraries, in addition to more traditional services
• Library staffing appears to be more unstable today than in 1989, with more libraries reporting a decrease in the number of staff.

Implications

• Hospital libraries continue to change in response to changes in the health care environment as health care administrators respond to financial pressures, library staff are downsized, degreed librarian positions are eliminated, and reporting structures change.
• MLA must continue to track the status of hospital librarians and libraries in light of the changing environment with surveys and other means, in partnership with others such as the National Network of Libraries of Medicine.

     

A computational fluid dynamics model for wind simulation: model implementation and experimental validation

To provide physically based wind modelling for wind erosion research at regional scale, a 3D computational fluid dynamics (CFD) wind model was developed. The model was programmed in C language based on the Navier-Stokes equations, and it is freely available as open source. Integrated with the spatial analysis and modelling tool (SAMT), the wind model has convenient input preparation and powerful output visualization. To validate the wind model, a series of experiments was conducted in a wind tunnel. A blocking inflow experiment was designed to test the performance of the model on simulation of basic fluid processes. A round obstacle experiment was designed to check if the model could simulate the influences of the obstacle on wind field. Results show that measured and simulated wind fields have high correlations, and the wind model can simulate both the basic processes of the wind and the influences of the obstacle on the wind field. These results show the high reliability of the wind model. A digital elevation model (DEM) of an area (3800 m long and 1700 m wide) in the Xilingele grassland in Inner Mongolia (autonomous region, China) was applied to the model, and a 3D wind field has been successfully generated. The clear implementation of the model and the adequate validation by wind tunnel experiments laid a solid foundation for the prediction and assessment of wind erosion at regional scale.
