SECONDARY SCHOOL AND UNIVERSITY STUDENTS’ INTEREST IN SCIENCE SUBJECTS IN CONNECTION TO THE CHOICE OF PROFESSION
2019
One of the most important factors influencing the welfare of the society is the development of science and technology, which in turn depends on scientists and students' science literacy. The aim of the study was to investigate the interest of high school and university students in science subjects, their views on factors that raise interest in subjects and play a determining role in the choice of profession. The questionnaire of Riga secondary school and university students about their interest in science subjects in connection to the choice of their profession was carried out. The results of the survey showed that the majority of university students are interested, or they have moderate i…
Pensamiento dominante, educación y medios de comunicación
2018
Comunicar es algo más que transmitir información. El desarrollo de la tecnología e internet han evolucionado el acto de comunicar en el mundo y se han creado nuevos espacios de comunicación. Los medios de comunicación suelen estar al servicio de un determinado poder, que puede ser público o privado. Sin embargo en este artículo se pone el acento en los intereses que tienen determinados poderes del ámbito privado y el uso que hacen de los medios de comunicación para defender y promover dichos intereses. No obstante, ese poder también puede dar lugar a formas de resistencias que sirvan para subvertir el orden establecido. Los medios de comunicación sirven como altavoces del pensamiento único …
Equilibrium open interest
2010
Abstract This paper analyses what determines an individual investor's risk-sharing demand for options and, aggregating across investors, what the equilibrium demand for options. We find that agents trade options to achieve their desired skewness; specifically, we find that portfolio holdings boil down to a three-fund separation theorem that includes a so-called skewness portfolio that agents like to attain. Our analysis indicates also, however, that the common risk-sharing setup used for option demand and pricing is incompatible with a stylized fact about open interest across strikes.
A Problem of Optimization in a Case of Foreign Investment
2000
The aim of the paper is to solve an optimization problem in an economic system with a central bank and a set of private agents. Each agent aims to maximize her expected utility, with rational expectations and being risk averse. The agents follow a profitability-risk criterium to face the portfolio diversification problem between foreign or domestic investment. An explicit formula for the optimal amount of foreign investment as a function of the expected exchange rate and an explicit formula for the exchange rate are obtained. These formulas show the hard influence of the expected exchange rate, the variance and the risk aversion on the agents’ decisions.
Exposición prenatal a drogas: Actuaciones de protección desde el Derecho Civil
2019
Los niños expuestos prenatalmente a drogas pueden ser considerados un caso especial de infancia en riesgo. La exposición prenatal a drogas se asocia a un amplio rango de complicaciones obstétricas y alteraciones neuroconductuales infantiles. Este trabajo analiza los diferentes mecanismos de protección de menores en situación de riesgo o desamparo que ofrece el Derecho civil, con especial referencia a las últimas reformas de 2015 que modifican la Ley Orgánica 1/1996, de Protección Jurídica del Menor, completando el estudio con las normas autonómicas existentes en la materia. Infants prenatally exposed to drugs can be considered to be a special case of infancy at risk. Prenatal drug exposure …
Design and Synthesis of 4-Substituted Indolo[3,2-e][1,2,3]triazolo[1,5-a]pyrimidine Derivatives with Antitumor Activity
2008
New derivatives of the indolo[3,2- e][1,2,3]triazolo[1,5- a]pyrimidine system, substituted in the 4 position, were designed as novel antitumor agents because of their theoretical capability to form stable complexes with DNA fragments. The calculated free energies of binding were found in the range -12.76 --> -39.68 Kcal/mol. The docking studies revealed a common binding mode with the chromophore intercalated between GC base pairs, whereas the side chain lies along the minor groove. Compounds, selected on the basis of the docking studies and suitably synthesized, showed antiproliferative activity against each type of tumor cell line investigated, generally in the low micromolar range. The mo…
Age and gender variations in the cone-beam computed tomographic location of mandibular canal: Implications for mandibular sagittal split osteotomy
2019
Background Mandibular sagittal split osteotomy (MSSO) may incur unfavorable split and sensorineural injuries. Knowledge of the anatomic location of the mandibular canal (MC) and bone thickness in the region of interest for MSSO, and the possible variations by age and gender can assist in avoiding such complications. Purpose: To study the location of the MC and bone thickness in the region of MSSO by cone-beam computed tomography (CBCT) radiographs and to evaluate the possible variations by age and gender in a Jordanian population. Material and Methods This retrospective radio-anatomical study examined all CBCT radiographs for patients treated over three years at the University of Jordan Hos…
Ecology and Diversity of Urban Pine Forest Soil Invertebrates in Rīga, Latvia / Augsnes Bezmugurkaulnieku Bioloģiskā Daudzveidība Urbānajos Priežu Me…
2015
Abstract A study on ecology and diversity of soil invertebrates of urban pine and mixed pine forests was carried out in seven different sampling plots in Rīga during 2014. Ninety eight soil samples were processed and in total, 40 426 specimens were extracted (of them, 25 237 specimens were identified to species level and 15 189 to order level). Indices (abundance, community similarity etc.) characterising faunal diversity and species communities of Rīga city soil fauna were estimated. The most numerous soil invertebrate groups were Collembola, Oribatida and Mesostigmata, accounting for 95% of all collected animals. There was rather high diversity of soil invertebrates in the disturbed urban…
Oxygen evolution reaction on a N-doped Co0.5-terminated Co3O4 (001) surface
2020
The project AP05131211 “First principles investigation on catalytic properties of N-doped Co3O4.” was funded by the Ministry of Education and Science of the Republic of Kazakhstan. The work was partly supported by COST (European Cooperation in science and Technology) Action 18234 (YM and EK). The work of T. Inerbaev was performed under the state assignment of Sobolev Institute of Geology and Mineralogy Siberian Branch of the Russian Academy of Sciences. YM and EK thank Sun-to-Chem project of ERA Net.
Old Principle of Liquid Ion-Impedance Spectrometry (Particularly in Milk) Realised by New Components
2020
Abstract Ion impedance spectrometry enables detection of the concentrations of multiple chemical compositions in a weak solution, usually if only part of a complex signal is used and the frequency is not swept. Prior to the method described in this paper, ion impedance required rather sophisticated electronics to collect the results from an instrument, as well as the electrode polarisation minimising. We elaborated and tested circuitry that uses the newest electronics components for a chemical analysis instrument designed according to a principle patented in Latvia (No. SU-1021440A), year 1981. The newly improved ion impedance spectrometry apparatus is suited for accurate measurement of ion…
