CHEMISTRY SELF-EFFICACY BELIEFS AS PREDICTORS OF STUDENTS' METACOGNITIVE SKILLS WHEN SOLVING CHEMISTRY PROBLEMS

This paper aims to explore (1) students’ chemistry self-efficacy beliefs and metacognitive skills during problem solving in chemistry, (2) a potential significant difference of chemistry self-efficacy beliefs and levels of metacognitive skills in accordance with subject fields and, (3) the level of chemistry self-efficacy beliefs as a predictor of metacognitive skills in the course of solving problems. For the specified purposes, “Metacognitive Activities Inventory” and “College Chemistry Self-Efficacy Scale” were administered to 80 undergraduate students, majoring in the Departments of Chemistry and Chemistry Education. This study employed the correlational research model as a type of quantitative research design. The results of the study reveal that students maintain high levels of chemistry self-efficacy as well as metacognitive skills when solving problems in chemistry. Regarding their subject fields, it has been observed that a significant difference exists merely in scores of “self-efficacy for psychomotor skills (SPS)” beliefs. The analyses also have shown that the levels of students’ metacognitive skills during problem solving predict solely the variable of “self-efficacy for cognitive skills (SCS)”, which accounts for 18.7 % of the total variance

Tuwati and Wasusarma: Imitating the behaviour of Assyria

This essay reviews the evidence concerning the Tabalian king Wasusarma and his father Tuwati, who appear in Neo-Assyrian and Urartian annals. The context for the removal of Wasusarma (Uassurme) from power by the Assyrian king is assumed to have lain in the events depicted in the large inscription of TOPADA. The historical and geographical import of this inscription is explored through a close reading of its historical portion, concluding that its background is set in a local struggle for power over north-western Cappadocia

Hemoglobin Q-Iran detected in family members from Northern Iran: a case report

<p>Abstract</p> <p>Introduction</p> <p>Hemoglobin Q-Iran (α75Asp→His) is an important member of the hemoglobin Q family, molecularly characterized by the replacement of aspartic acid by histidine. The first report of hemoglobin Q-Iran and the nomenclature of this hemoglobinopathy dates back to 1970. Iran is known as a country with a high prevalence of α- and β-thalassemia and different types of hemoglobinopathy. Many of these variants are yet to be identified as the practice of molecular laboratory techniques is limited in this part of the world. Applying such molecular methods, we report the first hemoglobin Q-Iran cases in Northern Iran.</p> <p>Case presentation</p> <p>An unusual band was detected in an isoelectric focusing test and cellulose acetate electrophoresis of a sample from a 22-year-old Iranian man from Mazandaran Province. Capillary zone electrophoresis analysis identified this band as hemoglobin Q. A similar band was also detected in his mother's electrophoresis (38 years, Iranian ethnicity). The cases underwent molecular investigation and the presence of a hemoglobin Q-Iran mutation was confirmed by the amplification refractory mutation system polymerase chain reaction method. Direct conventional sequencing revealed a single guanine to cytosine missense mutation (c.226G > C; <it>G</it>AC ><it>C</it>AC) at codon 75 in the α-globin gene in both cases.</p> <p>Conclusion</p> <p>The wide spectrum and high frequency of nondeletional α-globin mutations in Mazandaran Province is remarkable and seem to differ considerably from what has been found in Mediterranean populations. This short communication reports the first cases of patients with hemoglobin Q found in that region.</p

Hittitology today: Studies on Hittite and Neo-Hittite Anatolia in Honor of Emmanuel Laroche’s 100th Birthday

Il y a 100 ans, Emmanuel Laroche voyait le jour. Savant à la fois passionné de linguistique indo-européenne et d’Antiquité, il marqua durablement l’hittitologie par ses nombreuses contributions dans des domaines aussi variés que l’histoire des religions proche-orientales, la philologie cunéiforme ou encore la grammaire du hittite, du louvite et du hourrite. Ce colloque organisé en l’honneur de son centenaire a été l’occasion de faire le point sur les avancées de l’hittitologie actuelle, avancées auxquelles il participa tout au long de sa vie et qui se poursuivent après lui. Les axes thématiques qui sont abordés dans ce volume sont ceux qu’Emmanuel Laroche développa de son vivant, à savoir la linguistique des langues anatoliennes, la philologie et l’épigraphie cunéiforme et hiéroglyphique, les religions de l’Anatolie hittite et néo-hittite, l’histoire et la géographie historique, mais aussi l’archéologie proche-orientale, domaine qu’Emmanuel Laroche côtoya de près. Ajoutons à ces domaines celui de l’historiographie qui illustre, entre autres choses, l’impact des travaux d’Emmanuel Laroche dans l’hittitologie d’aujourd’hui.100 years ago, Emmanuel Laroche was born. As a scholar who was fascinated both by Indo-European Linguistics and Ancient Near Eastern and Classical Studies, he had a durable impact on Hittitology through his numerous contributions. His publications dealt with History of Near Eastern Religions, Cuneiform Philology, and Hittite, Luwian, and Hurrian grammar, among many other topics. This conference was organized in honor of his 100th birthday. Its aim was to discuss the recent developments in Hittitology, the ones to whom Emmanuel Laroche contributed and the ones which occurred after his time. The following themes are dealt with in this volume: Anatolian Linguistics, Cuneiform and Hieroglyphic Philology and Epigraphy, Religions of Bronze and Early Iron Age Anatolia, History and Historical Geography of Asia Minor, but also Near Eastern Archaeology, as Emmanuel Laroche was also very close to this discipline. Let us add to those fields Historiography which illustrates, among other things, the impact of Emmanuel Laroche’s work on today’s Hittitology
