Information literacy in continuing professional development of medical practitioners: a Croatian example

OBJECTIVES: This paper reports on the training of medical practitioners in information literacy. The course is carried out by an academic medical library in collaboration with its parent institution and the local physicians' licensing body. SETTING: The University of Zagreb Medical School (UZMS) developed an extensive continuing education programme for residents and practitioners, in partnership with the Croatian Chamber of Physicians. Within this programme, the Central Medical Library (CML) offers a hands-on course on searching and appraisal of medical information. DESCRIPTION: Continuing professional development (CPD) helps physicians update and develop the skills and knowledge they require in their everyday practice. The ability to locate, critically evaluate, and use medical information is an important component of CPD. The CML has developed a course entitled "Finding and Appraisal of Medical Information" which has been reviewed and accepted by its parent institution and the physicians' chamber. The course has been introduced in 2005 on a half-year base. OUTCOME: The course provides participants with the information on the most important medical information resources and with the basic skills needed for their effective usage. An evaluation questionnaire is used to assess the effectiveness of the course.     

Differential thermal expansion as a cause of salt decay: literature review,experiments, and modelling of micro and macro effects on Ançã limestone

Salt decay is one of the harshest, most frequent, and more complex types of decay of porous materials in built heritage, including natural stones, ceramics, and mortars. In this article, we address the mechanism of thermal expansion, which is one of the least studied, yet most controversial, of those proposed over time to explain salt decay. We present a review of scientific literature on the topic, followed by a study of the effects of thermal expansion on a specific material, the well-known Ançã limestone. The study included experimental measurement of the linear thermal expansion coefficient of the Ançã, both in its natural state and with varying contents of sodium chloride, sodium sulphate, or sodium nitrate. The results show that this coefficient: (i) is significantly higher when the stone is contaminated with salt; and (ii) scales approximately with the amount of salt contained in the stone pores, regardless of the type of salt. Based on these results and on modelling of damage modes at the microscopic and macroscopic levels, respectively, we conclude that thermal expansion can cause powdering, disaggregation, or other types of decay consisting of internal loss of cohesion. However, it is not likely to cause exfoliation of salt-loaded layers.

REACTION TIME AND INTELLIGENCE

The limited capacity theory is often cited to account for negative correlations between choice reaction time and different IQ measures. It is claimed, since working memory has strictly limited capacity to process a great amount of vital information and STM information decays if not rehearsed, that speed is an indispensable condition of efficient dealing with cognitive tasks. It ensures good performance before important information is forgotten. In the present experiment a special kind of task was applied‐one which supposedly puts a substantial load on the system of working memory. It was hypothesized that subjects dealing well with this task would also obtain high scores on general ability tests. The data obtained from 48 psychology students in the self‐paced, computer assisted study did not confirm this hypothesis. The data are interpreted as posing a challenge for the limited capacity theory, which must either be reformulated or replaced by better elaborated theoretical constructions.

     

On the testing of standards and standardized achievement testing: Panacea,placebo, or pandora's box?

Parents and educators concerned with the quality of education in Canadian schools have been subjected to a concerted campaign (through editorials, columns, and letters to the editor in major dailies and magazines, as well as a spate of books with alarmist titles) aimed at convincing them that the lack of adequate testing represents a major shortcoming and a stumbling block to educational reform. Provincewide and nationwide standardized achievement tests are offered as an indispensable tool to understand what works and what does not, to let parents know how schools are doing and how well their children are performing, and to make teachers and school boards accountable. Provincial education authorities are finding it increasingly difficult to resist the pressure, with Ontario the latest to jump on the testing bandwagon. However, although concerns about school curricula and about the best methods for testing student learning and performance are legitimate, the belief that standardized achievement tests are part of the solution to many ills allegedly afflicting our educational system does not stand up to the increasingly clear evidence of the many problems associated with the construction and administration of these tests, as well as the misuse and abuse of test scores. Far from being a panacea, this approach has proved to be fraught with dangers and adverse effects, from a narrowing of the curriculum to overemphasis of routine processes at the expense of higher learning skills, with virtually no empirical support for the purported benefits. With Canadian students facing the risk of being subjected to the same abuses as their U.S. counterparts, this paper reviews recent contributions and attempts to alert educators and policymakers to the serious deficiencies of this type of testing.     

Predictors of reading delay in deaf adolescents: the relative contributions of rapid automatized naming speed and phonological awareness and decoding

Deaf readers often fail to achieve age-appropriate reading levels. In hearing children, two cognitive factors correlated with reading delay are phonological awareness and decoding (PAD) and rapid automatized naming (RAN) of visual material. In this study we explored the contribution of these factors to reading and reading delay in a sample of deaf students (N = 49, mean age 13 years) whose reading age (RA) was around 7 years. Although PAD performance was poor in the deaf students compared with RA-matched hearing controls, it nevertheless correlated with their RA. Whether tested in sign or speech, RAN was much faster in the deaf group than in RA-matched hearing controls but showed no direct relationship with reading level or reading delay. We conclude that in contrast to PAD, which is a factor in both deaf and hearing reading achievement, RAN may be only indirectly related to reading in deaf students.     

US and Turkish preschoolers’ observational knowledge of astronomy

The purpose of this cross-cultural study was to describe and compare US and Turkish children's observational knowledge of the day and night cycle and to identify similarities predicted by framework theory. Fifty-six (27 US and 29 Turkish) young children (ages 48–60 months) participated in the study. Semi-structured interviews were individually conducted, digitally recorded, transcribed, and analyzed using the constant comparative method. The results demonstrate that preschoolers from the two cultures are able to make comparable informal observations of the sky, and their observational knowledge includes many similarities, with one exception, as predicted by framework theory. US children were more likely to perform better than the Turkish children on the question about the time of observation for the moon. Although science concepts and skills are better represented in US early childhood education programs than the Turkish program, the results suggest that this advantage did not translate into performance differences between US and Turkish children.
