Adolescent Learning of Academic Vocabulary in Iceland

The fields of vocabulary instruction, literacy professional development, and global language issues framed this research. Situated in Iceland, the intervention consisted of professional development for 10th‐grade teachers focused on academic words in various subject materials, increasing the learners’ proficiency in using explicit strategies to detect word meanings, and offering learners multimodal ways of working with the vocabulary. There were no significant differences between the participants in the experimental schools (n = 157) and in the control schools (n = 88). There were gains from pretest to posttest in vocabulary and in comprehension, and there were some promising trends that distinguished the experimental group from the control group on the reading comprehension test. The nature, intensity, and length of the professional development offered to the high school teachers and the relatively short time of measurement of student outcomes are suggested explanations of the results.Fulbright Foundation/U.S. State DepartmentPre-prin

Does Plato criticize art in the Republic?

As widely known books II, III and X in the Republic contain various examples of what may seem to be criticism of art. These include criticism of the works of famous poets such as Homer and Hesiod, and artistic disciplines as for instance poetry and painting. However, even if Plato may have criticized art, it does not follow that he disapproves of art as such. It is not certain that he is generally hostile towards artistic practices such as painting and composing poetry although he may have been critical to particular works. The purpose of this paper is to clarify whether or not Plato’s criticism is indeed a criticism of art as such

Severe vitamin D deficiency is common in critically ill patients at a high northern latitude.

To access publisher's full text version of this article click on the hyperlink at the bottom of the pageCritically ill patients at southern latitudes have been shown to have low vitamin D levels that were associated with prolonged hospital stay. To our knowledge no studies have been conducted on vitamin D status amongst critically ill patients at high northern latitudes. Despite the Icelandic population traditionally taking vitamin D supplements, we hypothesized that the majority of critically ill patients in Reykjavik, Iceland have low vitamin D levels.This was a prospective observational study on 122 patients admitted to Landspitali University Hospital intensive care unit. Serum vitamin D (25(OH)D) was measured in all patients on two occasions (first and second day). The prevalence of vitamin D deficiency and its effect on hospital stay was calculated.Only 9% of patients had vitamin D levels recommended for good health (>75 nmol/l) and 69% were deficient (25(OH)D < 50 nmol/l). The average difference between the first and second vitamin D samples was 2.8 nmol/l. Forty-three percentage of the severely vitamin D deficient stayed in the ICU for more than 4 days compared to 19% of patients with better status (P = 0.196).Vitamin D deficiency is very common in critically ill patients at high northern latitudes and patients with severely deficient vitamin D levels had trend towards longer intensive care unit stay. Furthermore, 43% of the patients had vitamin D levels under 25 nmol/l that is associated with osteomalacia. It appears that a single vitamin D measurement gives a reasonable clue about the vitamin D status in critically ill patients.Landspitali University Hospital Research Fund University of Iceland Research Fund, Reykjavik, Icelan
