Introduction
The study was performed to compare and analyze the inter-departmental variability in the request of rarely requested laboratory tests in primary care, as opposed to other more common and highly requested tests.Materials and methods
Data from production statistics for the year 2012 from 76 Spanish laboratories was used. The number of antinuclear antibodies, antistreptolysin O, creatinine, cyclic citrullinated peptide antibodies, deaminated peptide gliadine IgA antibodies, glucose, protein electrophoresis, rheumatoid factor, transglutaminase IgA antibodies, urinalysis and uric acid tests requested was collected. The number of test requests per 1000 inhabitants was calculated. In order to explore the variability the coefficient of quartile dispersion was calculated.Results
The smallest variation was seen for creatinine, glucose, uric acid and urinalysis; the most requested tests. The tests that were least requested showed the greatest variability.Conclusion
Our study shows through a very simplified approach, in a population close to twenty million inhabitants, how in primary care, the variability in the request of laboratory tests is inversely proportional to the request rate.Key words: primary care, laboratory proficiency testing, clinical laboratory services, test requesting, preanalytical phase 相似文献53.

Introduction
Pre-preanalytical and post-postanalytical phases are steps where the laboratory professional may play a crucial role. Measuring the serum circulating 25 hydroxyvitamin D level (25(OH)D) is recommended to evaluate vitamin D status in patients at risk for vitamin D deficiency while 1,25 hydroxyvitamin D (1,25(OH)2D) is only recommended to monitor several particular conditions (chronic kidney disease, hereditary phosphate-losing disorders, and some other) clearly defined by the current clinical guidelines of Endocrine Society.Our research hypothesis was that through education and communication through comments in the Laboratory Information System (LIS), we could improve appropriateness in the request vitamin D tests.
Materials and methods
A retrospective observational cross-sectional study was conducted from January 2005 to December 2014. Each 1,25(OH)2D request was reviewed individually by a member of the laboratory staff. Starting in November 2011, each inappropriate 1,25(OH)2D request was registered in LIS and 25(OH)D was measured instead of 1,25(OH)2D. We counted the overall number of 1,25(OH)2D requests and the number of inappropriate requests which then were marked with a comment.Results
The request of 25(OH)D increased along years. However, 1,25(OH)2D requests increased until 2012 when demand began to diminish.Conclusions
Education and communication through comments in the LIS, corrected the inappropriate request of 1,25(OH)2D and promoted the use of 25(OH)D to study vitamin D deficiency.Key words: clinical laboratory services, utilization, vitamin D, communication, education 相似文献54.

This article discusses how a male Karenni refugee in the United States has constructed multilingual capital along the way of his multiple movements across national borders. As a member of an ethnic minority group in three different countries (Burma, Thailand, and the United States), he has invested in learning multiple languages throughout the movements. Based on a two-year ethnographic study on the participant’s multilingual practices, I argue that being multilingual is a fundamental part of his transnational identities, economic security, and agentive acts. His roles outside formal classroom settings as a language broker, refugee, and an ESL tutor have been shaped by a continuum, or horizontal relationship of languages. The study suggests the inclusion of adult students’ transnational identity and multilingual practices outside a language classroom. In addition, a career that requires multilingual skills and transnational knowledge should be encouraged and created for newcomers. 相似文献

It is a fact that the most important thing for transmitting cultural heritage to posterity starts with a sensitive documentation step. Up to the present, there have been many developments in documentation of cultural heritage by developing technology, and contemporary documentation techniques have progressed speedily. Nowadays besides of a sensitive documentation, rapidness has gain importance for the sake of time and cost. Because of these facts, the techniques that provide fast and reliable documentation and modeling like digital close-range photogrammetry and laser scanning became preferable with respect to classical architectural methods. In this paper, the studies of precise measurement, 3D modeling and documentation of Nippur Cubit is presented. The Nippur cubit–the first known standard measure of length–was a heavy copper bar, unearthed at Nippur on the Euphrates River dating from about 2650 B.C. This ancient measuring device is nowadays exposed in the Archeological Museum of Istanbul, Turkey. For the purpose of 3D modeling and archiving of the mentioned object, digital close-range photogrammetry and laser scanning technology were applied and results obtained from these two techniques were compared. 相似文献

Influence of a catalan peer tutoring programme on reading comprehension and self‐concept as a reader
This study relates to the results obtained in the development of reading comprehension (RC) and self‐concept as a reader in students who participated in Llegim en parella (Reading in pairs), a Catalan peer tutoring programme. The research combines a quasi‐experimental design with the use of comparison groups and pre‐tests/post‐tests for both variables; a qualitative approach is adopted by analysing the interactions in order to detect influencing factors. Statistically significant results were obtained for all students in terms of RC but only for student tutors in relation to reading self‐concept. The factors involved in the improvements identified in RC are: reading strategies, scaffolding in inferential and deep comprehension questions. Regarding self‐concept, the tutor's own role, his involvement with their tutees' progress, reading aloud and the metacognitive reflection processes, are all factors that enable us to explain the improvement in the tutor's reading self‐perception. The positive influence of peer tutoring on the development of reading competence through this programme is clearly evident. 相似文献

The primary aim of the present study was to examine longitudinal models to determine the function that best describes developmental change in processing speed during childhood and adolescence. In one sample, children and adolescents (N= 503) were tested twice over an average interval of 2 years on two psychometric measures of processing speed: Visual Matching and Cross Out. In another sample, children and adolescents (N= 277) were tested four times, every 6 months, on Cross Out. Age-related changes in performance on both tasks were examined using six longitudinal models representing different hypotheses of growth. Linear, hyperbolic, inverse regression, and transition models yielded relatively poor fit to the data; the fit of the exponential and quadratic models was substantially better. The heuristic value of these latter models is discussed. 相似文献

In this study, we aimed to ascertain whether it is possible to create reading contexts that eliminate the impact of word recognition on reading comprehension and permit pupils with reading disabilities (RD) to attain a level of comprehension similar to that of their peers without RD. Specifically, the study compared a traditional reading situation with one of reading with aids (joint reading). In both situations, pupils' comprehension level was assessed by means of a summary and a series of inferential questions, and we controlled the effect on comprehension of word recognition, previous knowledge, rhetorical competence, and working memory. The results showed that the aids provided during reading do not eliminate the effect of word recognition, but they do permit readers with RD to attain a comprehension level similar to that of their peers. 相似文献

The purpose of this study was to continue the investigation into the cognitive domain of communicative competence (Duran & Kelly, 1984; McCroskey, 1982; Spitzberg, 1983). The relationship between interaction involvement (Cegala, 1981) and communicative adaptability (Duran, 1983), a communicative competence construct, was studied. Canonical correlation analysis produced three significant canonical roots. Root 1 was defined by social confirmation appropriate disclosure, and responsiveness. Root 2 was defined by social composure, social experience, andperceptiveness. Root 3 was defined by social experience, and attentiveness. The theoretical implications of the results as well as suggestions for future research are discussed. 相似文献
