Journal reading patterns and preferences of pediatricians.

PURPOSE: To describe the journal reading patterns of pediatrician members of the American Academy of Pediatrics (AAP) and compare results to similar surveys of medical faculty and physicians. The research also explored factors that might influence changes in reading patterns in the future, such as adoption of PDA technology. METHODOLOGY: A random sample of 2,000 AAP members was drawn from the AAP membership list, with paper surveys distributed in mid-2004. SETTINGS/SUBJECTS: Six hundred sixty-six pediatrician AAP members participated in a survey of reading behavior, with a total of 1,351 members answering some questions about technology use. RESULTS: The hypotheses that pediatricians read many journal articles each month, read each article on average quite quickly, read heavily from personal subscriptions, read from both print and electronic journals, and read for many purposes were all supported. Pediatricians read journal articles primarily for current awareness and most often rely on quick reading from print journals for current awareness. Reading for research, writing, and presentations are more likely from library-provided electronic journals. DISCUSSION/CONCLUSION: Convenience and purpose of reading are key factors that explain reading patterns of pediatricians. Print personal subscriptions are convenient for current awareness reading, while electronic journals systems are convenient for reading for research because they provide access to a broader range of journals. Publishers and librarians must understand the purposes and patterns of reading to design appropriate journals and services. Pediatricians read many current articles very quickly and from many different locations. Pediatricians under the age of thirty-five are more likely to use PDAs, suggesting that articles delivered to a handheld device might be accepted as convenient in the future.

Nonhabitual seizures in patients with implanted subdural electrodes.

The implantation of subdural electrodes has been widely employed in the invasive monitoring of patients with medically refractory epilepsy. The use of subdural electrodes, though, has been associated with rare but occasionally troublesome complications. We report the occurrence of nonhabitual seizures after implanting subdural grid electrodes. Among 57 patients diagnosed with medically refractory epilepsy who were evaluated in our department over a 12-month period, 21 patients underwent craniotomy for subdural grid/strip electrode implantation. Subdural grids and strips (AdTech, Racine, Wisc., USA) were used for continuous video EEG monitoring. In 3 patients, during subdural monitoring, consistent nonhabitual seizure activity was recorded. This was both clinically and electrographically different than the patients' habitual seizures. The patients' nonhabitual seizures disappeared postoperatively after removing the implanted electrodes. The occurrence of nonhabitual seizures, though quite rare, could lead to mislocalization of an epileptogenic focus. This complication might be the result of direct mechanical cortical irritation or chemical irritation caused by blood breakdown products. The occurrence of nonhabitual seizures comes to add itself to the existing list of complications associated with employment of subdural electrodes for invasive monitoring.

Medical faculty's use of print and electronic journals: changes over time and in comparison with scientists.

OBJECTIVES: The objectives are to determine how medical faculty members use scholarly journals, whether print or electronic journals are read more, whether there is a pattern among types of users, and what similarities and differences there are between the use of journals by medical faculty and faculty in other disciplines. METHODS: Medical faculty of the University of Tennessee Health Science Center (UTHSC) multi-campus system were surveyed, and their responses estimated using critical incident technique to characterize the different aspects of their use of print and electronic journals. RESULTS: Medical faculty read a great deal, especially compared to scientists. The most frequently reported principal purpose of reading is to support their primary research (30% of reading). The majority of reading comes from recently published articles, mostly from personal subscriptions. Medical faculty continue to rely on print journals (approximately 70% of readings) versus electronic journals. Age of faculty does not appear to influence the choice of print or electronic format. Medical faculty read more articles than others on average and need information digested and verified in a way to save them time. Convenience and currency are highly valued attributes. CONCLUSIONS: It can be asserted that librarians and publishers must find ways to provide the attributes of convenience and currency and match the portability of personal subscriptions in an electronic journal format for medical faculty.

Publicación de revistas electrónicas: economía de su producción, distribución y uso

Se analizan aspectos económicos de la actividad de publicación de revistas académicas y científicas, a partir de los costos de producción y de la revisión de los datos disponibles al respecto. Se establece una comparación entre la producción de revistas impresas en papel y en formato electrónico. Se discuten las políticas de precios de suscripción y se ofrece una guía para establecer un punto de equilibrio que ayude a las bibliotecas a optar entre suscribirse a las revistas y obtener copias de artículos mediante los servicios de préstamo interbibliotecario y de envío de documentos.

This paper analyses economic aspects of the scientific scholarly journal publishing, based on production costs and use data. It compares the production of traditional journals with electronic journals, discussing price policies for subscriptions and providing a guide to assess breakeven points, helping libraries to face the option of subscribing to journals or obtaining separate copies through intelibrary borrowing or document delivery.
