Library support for problem-based learning: an algorithmic approach

Academic health sciences libraries can take various approaches to support the problem-based learning component of the curriculum. This article presents one such approach taken to integrate information navigation skills into the small group discussion part of the Pathophysiology course in the second year of the Dental school curriculum. Along with presenting general resources for the course, the Library Toolkit introduced an algorithmic approach to finding answers to sample clinical case questions. While elements of Evidence-Based Practice were introduced, the emphasis was on teaching students to navigate relevant resources and apply various database search techniques to find answers to the clinical problems presented.     

Dysthymic Symptoms,Hostility and Scholastic Achievement in a Group of High‐school Students

In order to investigate the possible relationship between dysthymic symptoms, hostility levels and scholastic achievement, the self‐rating scales, DSSI/sAD (Delusions Symptoms States Inventory/states of Anxiety and Depression) and HDHQ (Hostility and Direction of Hostility Questionnaire), were given to a group of 754 high‐school students (grades 10‐12: 387 males, 367 females) two weeks before the June examinations. Negative relationships between dysthymic symptoms and school performance were detected in both males and females. Hostility subscales were also found to be negatively related to performance, especially the extrapunitive ones. All findings were more prominent in the females.     

Narrative Fiction and Expository Nonfiction Differentially Predict Verbal Ability

Although reading is known to be an important contributor to language abilities, it is not yet well established whether different text genres are uniquely associated with verbal abilities. We examined how exposure to narrative fiction and expository nonfiction predict language ability among university students. Exposure was measured both with self-report and with recognition tests of print exposure. Verbal ability was measured in the form of synonym knowledge, analogies, sentence completion, and reading comprehension in 4 different studies. Across all studies, narrative fiction was a better predictor of verbal abilities relative to expository nonfiction. When examining unique associations, controlling for demographic variables and the other genre, fiction remained a robust predictor, whereas nonfiction became a null or weak negative predictor. In light of this evidence, it appears that what we read plays an important role in how reading contributes to language development.     

Tracking changes in pre-service EFL teacher beliefs in Greece: A longitudinal study

This article reports on a longitudinal study that aims to investigate pre-service EFL teacher beliefs about learning and teaching in Greece. The study attempts to track possible changes in those beliefs during a 3-year teacher education program and explores the impact of teaching practice, in particular, on student teachers’ beliefs. The results indicate that while there is a gradual and sometimes significant development in student teachers’ beliefs during the program, student teachers’ engagement in the teaching practice seems to have a low impact on the development of their beliefs. Those findings are interpreted with reference to the structure and context of the specific teacher education program and can be useful for the design and development of EFL teacher education programs.     

Royalties for Artists versus Royalties for Authors and Composers

Legislation creating or reinforcing resale royalties for visual artists retains substantial political popularity – particularly in the European Union – despite the often skeptical attitude toward those rights in the economics literature. In this essay, we probe more deeply the affirmative arguments that can be made for a resale royalty right, in either a mandatory or a discretionary form. We also compare the rationale for visual artists' resale royalties with the potential rationales for the now-well-established systems of royalty rights for authors and composers. This comparison has particular interest both because some of the principal arguments made against visual artists' resale royalties also apply to authors' royalties, and because the economic rationale for compensating authors with royalties has itself not been well explored. We also discuss briefly the related subject of display rights for visual artists. We conclude with some general implications for policy.     

Endothelins -- clinical perspectives

Endothelins (ET) are a group of endogenous peptides, which have a strong and long-lasting vasoconstrictive effect. Three isoforms of endothelins coded by three different genes have been identified to date. Endothelin-1 (ET-1) is the most potent vasoconstrictive agent currently identified, and it was originally isolated and characterized from the culture media of aortic endothelial cells. Two other isoforms, named endothelin-2 (ET-2) and endothelin-3 (ET-3), were subsequently identified, along with structural homologues isolated from the venom ofActractapis engaddensis known as the sarafotoxins. The biological effects of endothelin production are determined via activation of one or two G-protein coupled receptors, endothelin receptors A (ETRA) and B (ETRB1 and ETRB2). Recently endothelin receptor C (ETRC) was discovered, however, its functions and distribution still remain unclear. The effects mediated by ET-1 via ETRA are vasoconstriction, bronchoconstriction and secretion of aldosterone. Agonists related to the ETRB1 activation cause vasodilatation by stimulating NO, PGI2 and endothelium-derived hyperpolarizing factor (EDHF). In contrast, coupling to ETRB2 causes vasoconstriction. Involvement of ET has been demonstrated in the pathophysiology of certain disorders. In this review, we discuss the physiological and pathophysiological role of endothelium-derived ET-1, the pharmacology of its two receptors, focusing on the role of ET-1 in the development of some pathophysiological conditions.

Design and evaluation of a computer game for the learning of Information and Communication Technologies (ICT) concepts by physical education and sport science students

This study addresses the learning of Information and Communication Technologies (ICT) concepts by physical education and sport science students through a computer game. Its aims are: (a) the design of the prototype of a computer game aimed at supporting the development of an appropriate mental model about how a computer works by the students, and (b) the evaluation of the impact of the use of this prototype on students as to appeal, basic usability issues and learning outcomes. The most significant elements of the game prototype (narrative, characters, interface, scenarios, puzzles, gameplay) are presented in connection with the constructivist learning principles that guided the game design. A hundred and three (103) physical education and sport science students participated in the evaluation of the game prototype, which was conducted through pretest and posttest written questionnaires that elicited both quantitative and qualitative data. The data analysis showed that the game prototype was well-accepted as an alternative learning tool for ICT, compared to traditional learning tools, and that most game elements elicited average to positive responses from the students. It was also found that the game prototype had a significant positive effect on students’ knowledge regarding the concepts of input, program, output and their interplay, and that it helped certain students overcome their misconceptions and form more scientifically acceptable and elaborate mental conceptions about basic functions of a computer. Future improvements and extensions to the game as well as future research perspectives are discussed on the basis of the findings.
