The Question of Creativity in the Finnish Elementary School Curriculum

2017

This article is intended to examine the role of creative education in the design of the national curriculum and the division of lesson hours during the period 2010-2014. During this process, pupils, private citizens and experts from different fields were given the opportunity to submit their contributions to the exercise. The article intends to examine whether the curriculum development exercise fulfilled the conditions for a wide democratic consultation process. Three professional groups, elementary school teachers, artists (writers, visual arts teachers, musicians) and academic engineers (n= 1163) were the main focus of this research project. Creativity related claims, which were posted o…

Specificity of Reading Self-Efficacy Among Primary School Children

2018

We investigated the specificity of reading self-efficacy among second- to fifth-grade children in Finland (N = 1,327). Bandura (1997 Bandura, A. (1997). Self-efficacy: The exercise of control. New York, NY: Freeman. [Google Scholar] ) theorized that efficacy beliefs can be assessed at different levels of specificity; however, empirical support for this view is scarce among young children. Efficacy beliefs targeting reading-related activities were assessed at three specificity levels (general, intermediate, and specific). Confirmatory factor analysis revealed that these specificity levels are separable, but correlated, and the structure was invariant across gender and grade level. Self-effic…

The perception of odor objects in everyday life: a review on the processing of odor mixtures

2014

International audience; Smelling monomolecular odors hardly ever occurs in everyday life, and the daily functioning of the sense of smell relies primarily on the processing of complex mixtures of volatiles that are present in the environment (e.g., emanating from food or conspecifics). Such processing allows for the instantaneous recognition and categorization of smells and also for the discrimination of odors among others to extract relevant information and to adapt efficiently in different contexts. The neurophysiological mechanisms underpinning this highly efficient analysis of complex mixtures of odorants is beginning to be unraveled and support the idea that olfaction, as vision and au…

El aprendizaje-servicio : una estrategia para la formación de competencias en sostenibilidad

2015

El artículo presenta la estrategia docente del Aprendizaje-Servicio como herramienta para desarrollar competencias vinculadas al reto de la sostenibilidad, tal y como establecen las directrices de la Conferencia de Rectores de las Universidades españolas (CRUE) y otras instancias institucionales a nivel local y global. Se analiza la experiencia docente de la autora, que ha utilizado la metodología del aprendizaje-servicio en la enseñanza universitaria para la formación de futuros y futuras profesionales de la educación en el logro de competencias clave exigidas por el desarrollo sostenible: el análisis crítico, la reflexión sistémica, la toma de decisión colaborativa, y el sentido de respon…

Some observations on the use of matrix modifiers in the determination of aluminum by electrothermal atomic absorption spectrophotometry

1989

Abstract Some evidence demonstrating that the use of matrix modifiers is necessary to obtain good calibration lines in the determination of aluminum by graphite furnace atomic absorption spectrophotometry is provided. It was found that the most sensitive results were obtained when Mg(NO 3 ) 2 was used instead of NH 4 H 2 PO 4 .

Determination of platinum and iridium in reforming catalysts by second derivative and absorptiometric spectrophotometry

1991

Investigations on the spectrophotometric determination of platinum as a complex formed by tin(II)chloride in hydrochloric acid are reported. The determination of platinum was found to be interfered with by iridium, because it also forms a complex with tin(II) chloride. The features of the derivative absorption spectrophotometry for the quantitative determination of platinum and iridium was also studied. The analytical application of the method for the determination of platinum and iridium in catalysts was investigated.

Sodium Chloride and Magnesium Chloride affected by Ripening of Camembert Cheese

1993

Ripening of cheese with three kinds of salt treatment was studied using MgCl 2 , NaCl or a mixture of the two. Proteolysis was followed by determination of TCA-soluble nitrogen and quantitative electrophoresis. A rapid one-step method for free fatty acids was used to determine short and long-chin fatty acids. In the presence of magnesium, proteolysis increased, even with NaCl, which seemed to delay the magnesium activation. Lipolysis was retarded by NaCl, which decreased the level of free fatty acids. An imbalance between proteolysis and lipolysis could be responsible for the unpleasant flavor of the cheese containing both MgCl 2 and NaCl

Fluoride ingestion and thyroid function in children resident of naturally fluoridated areas - An observational study

2019

Background Literature shows association between systemic fluorides with water fluoride level above 3ppm and endocrine disorders especially related to thyroid. Aim & Objectives: To estimate serum T3, T4, TSH, Fluoride levels among children with normal nutritional status and optimal iodine intake, residing in three different ranges of drinking water fluoride levels below 3ppm. Material and methods Present double blinded observational trial comprised of 293 children aged between 9-13 years consuming naturally fluoridated water of 3 different ranges: Group I: 0.01 - 0.6ppm, Group II: 0.7-1.2ppm and Group III: 1.3-1.8ppm. For each child demographic data, BMI and Clinical Fluorosis Index were rec…

Visualization of inert gas wash-out during high-frequency oscillatory ventilation using fluorine-19 MRI

2010

High-frequency oscillatory ventilation is looked upon as a lung-protective ventilation strategy. For a further clarification of the physical processes promoting gas transport, a visualization of gas flow and the distribution of ventilation are of considerable interest. Therefore, fluorine-19 magnetic resonance imaging of the imaging gas octafluorocyclobutane (C(4) F(8) ) during high-frequency oscillatory ventilation was performed in five healthy pigs. For that, a mutually compatible ventilation-imaging system was set up and transverse images were acquired every 5 sec using FLASH sequences on a 1.5 T scanner. Despite a drop in signal-to-noise ratio after the onset of high-frequency oscillato…
