The Influence of Production Parameters on Pozzolanic Reactivity of Calcined Clays
Authors: Danner Tobias , Justnes Harald 
Published: January 2019

Abstract
Calcined clays are gaining increasing interest as future supplementary cementitious materials for the production of blended cements. Besides the mineralogy, the right production conditions can affect the pozzolanic activity of calcined clays. In this paper, the pozzolanic reactivity of two calcined natural clays in dependence of burning temperature, residence time in the furnace, cooling conditions and particle size of the final product is investigated. The highest pozzolanic reactivity was found at calcination temperatures between 600 and 800°C. While different cooling conditions had no identified effect on reactivity, decreased particle size and residence time increased the reactivity.
Gaming for Introducing Social Challenges and Responsibility to Young People
Authors: Perko Igor , Mendiwelso-Bendek Zoraida 
Published: January 2019

Abstract
Gaming has the potential to support the development of young people’s capabilities in social responsibility (SR) and, at the same time, represents a threat of developing undesired behaviour patterns. Successful integration of gaming in the lives of young people requires a systemic approach, which, to the best of our knowledge, hasn’t been provided in the literature. We provide insight into this issue. In this paper, multiple methods are used. To elaborate the backgrounds on the gaming’s effects and social behaviour, the literature is analysed. To assess the state-of-the art of young people characteristics, their pressing social challenges and gaming evaluation reports are analysed. The synthesis is provided and placed in the context with social responsibility properties using system dynamics. Gaming concepts, appropriate for education for SR, and relationships between young people’s challenges and the players in the gaming environment in SR terms are proposed. Currently, the loop of games development is negatively propelled by the short-term games demand. We propose effective feedback loops, linking young people and their social environment, using a SR tool set to provide demands to the game providers. The experience will support the games developers to design socially constructive games, aiming to develop the desired skills and competencies in social transformation processes of young people toward SR. The proposed model provides merely an overview model, designed by the literature review and state-of-the-art analysis. To fully understand the games’ effects on young people, a more detailed analysis is required.

Abstract

Introduction: The term angiodysplasia (AD) refers to acquired malformation of the blood vessels (communications between veins and capillaries), frequently found within the gastrointestinal mucosa and submucosa. AD of stomach and duodenum are cause of upper gastrointestinal bleeding in 4%-7% of patients. The means of treatment are usually endoscopic, including argon plasma coagulation (APC), electrocoagulation, mechanical hemostasis by clippsing, laser photo-coagulation and injection therapy.

Aim: To compare the success rate, and adverse events (ulcer lesions, perforations) of APC and injection therapy in the treatment of bleeding angiodysplasia in the upper gastrointestinal tract (GIT).

Material and Methods: In a prospective study including 50 patients with bleeding angiodysplasia of the upper GIT, 35 patients were treated with APC, and remaining 15 with injection therapy using adrenaline and 1.5% solution of polidocanol. Follow-up period was 6 months.

Results: A total of 50 patients aged 18 to 64 years, 64% male and 36% female, have been treated during 2 years period. The rate of recurrent bleeding and side effects was significantly higher in the adrenaline group (p <0.01). Blood transfusion was required in 68% during the first hospital admission. Angiodysplasia of the stomach was present in 66%, versus 34% in duodenum.

Conclusion: Endoscopy is “gold standard” for diagnosis and treatment of AD in the gastrointestinal tract. The study unveiled APC as more effective treatment option with lower degree of complications and adverse events in comparison to injection therapy in patients with bleeding AD.

Published: January 2019

Abstract
The performance of Arabica coffee (Coffea arabica L.) depends on the climate, soil, pests, and elevation. Information on the performance of Arabica coffee growing in the changing climate of North Sumatra has not been available so far. To provide such information, 28 genotypes were studied. The nested design used three factors. Seven climate zones, two locations in each climate zone, and two coffee farms (genotype, G) in each location were selected. The research showed that the genotypes were highly significantly different (α = 0.01). G5, G6, and G20 produced the heaviest hundred beans. G13, G19, and G25 suffered the least coffee berry borer infestation (CBBI). The length of rainy season became the most important factor (r2 = 0.54). The CBBI (y, %) correlated significantly and negatively with the elevation (x, m) with the equation of y = 46.4 – 0.025x. The climate zones showed a significant difference (α = 0.05). The genotypes produced heavy beans also in two wet months of the rainy season and one dry month. The temperature (x, °C) was the most important factor affecting CBBI (r2 = 0.65) with the equation of y = –338.2 + 15.5x. The soil pH correlated significantly and positively with beans weight and bean width.

Published: January 2019

Abstract
This paper investigates, using a multi-product paradigm, the market structure of the Iranian banking sector to evaluate the role of scale. In so doing, we checked for economies of scope by multi-product cost function as well as the impact of potential economies on the banking sector structure including 18 banks during the period 2008–2014. The changes in Panzar-Rosse H-Statistic as a result of the variety in products reflect changes in the monopolistic power. The results show that an increase in the variety of offered products increases banks’ monopolistic power.
Gold Exchange Traded Fund - Price Discovery and Performance Analysis
Authors: Mallika Mathew , Sulphey M. M. 
Published: January 2019

Abstract
The paper aims to examine the price discovery process and the performance of Gold Exchange Traded Funds especially with respect to two Gold ETFs, namely, Goldman Sachs Gold Exchange Traded Scheme (GoldBeEs) and SBI Gold Exchange Traded Scheme (SBIGETS), for the period 2009 – 2016. The study has employed Johansen cointegration and Johansen’s Vector Error Correction Model (VECM) for the price discovery analysis. The results of VECM reveal that the spot prices lead the Gold ETFs price during the study period. Tracking Error analysis shows that Gold ETFs have neither outperformed nor underperformed the spot price. Price Deviation analysis indicates that Gold ETFs are trading on an average lower than the spot price of gold. The entire analysis reveals that although the price discovery takes place in the spot market, Gold ETFs have performed as well as physical gold and the slight difference in price with that of Gold is only because of certain fees, which are applicable in the management of Gold ETFs.
On the Gains of Using High Frequency Data in Portfolio Selection
Authors: Brito Rui Pedro , Sebastião Helder , Godinho Pedro 
Published: January 2019

Abstract
This paper analyzes empirically the performance gains of using high frequency data in portfolio selection. Assuming Constant Relative Risk Aversion (CRRA) preferences, with different relative risk aversion levels, we compare low and high frequency portfolios within mean-variance, mean-variance-skewness and mean-variance-skewness-kurtosis frameworks. Using data on fourteen stocks of the Euronext Paris, from January 1999 to December 2005, we conclude that the high frequency portfolios outperform the low frequency portfolios for every out-of-sample measure, irrespectively to the relative risk aversion coefficient considered. The empirical results also suggest that for moderate relative risk aversion the best performance is always achieved through the jointly use of the realized variance, skewness and kurtosis. This claim is reinforced when trading costs are taken into account.
UM NOVO OLHAR SOBRE A ESCOLA – O LUGAR DA INOVAÇÃO NA CONSTRUÇÃO DE POSSIBILIDADES E AVANÇOS EMANCIPATÓRIOS
Authors: Palma Gisele 
Published: January 2019

O presente texto propõe a reflexão referente aos movimentos inovadores que ocorrem na educação, tensionados às demandas do cotidiano da prática docente.O mesmo foi organizado a partir dos estudos realizados pela autora em duas pesquisas concluídas e duas em andamento. As investigações revelam as possibilidadesde um novo olhar sobre a escola, no sentido de percebê-la enquanto lugar de formação docente e produtora de saberes – potencialmente transformadora dasrelações sociais hegemônicas, buscando a emancipação dos excluídos e secularmente marginalizados. Aponta, também, para a construção de uma escola entendidacomo alternativa possível frente à “crise – de significados da vida humana, das relações entre as pessoas, instituições, comunidades” (RIOS, 2002a, p. 39 – grifo do autor), a qual se configura na contemporaneidade. Distanciada de uma concepção romantizada da educação, a autora busca elementos que venham a contribuir paraa compreensão dos movimentos inovadores, percebidos como rupturas paradigmáticas. Conclui-se que esses fenômenos assumem um caráter pedagógico e multiplicador de uma nova lógica, capaz de provocar profundas mudanças, não só nas práticas docentes, mas, também, nas comunidades envolvidas em tais processos.Pa l a v r a s - C h a v e : Inovação, Formação Continuada, Saber Docente, Emancipação.

Authors: De Almeida Stefânia Ordovás , Müller Hugo Fridolino 
Published: January 2019

O crescimento do uso da Internet, primeiramente nos países desenvolvidos, e, posteriormente, em todo o mundo, deu vazão a uma nova forma de comunicaçãoentre empresas e consumidores: as comunidades de marca virtuais. O surgimento destas comunidades é um tema atual e relevante, sobre o qual os estudos recentes ainda não responderam a uma importante questão: é melhor para as organizações criarem suas comunidades de marca ou deixá-las fluir por parte da iniciativa dos consumidores? Neste trabalho propõe-se um modelo teórico que, após discussão pela comunidade de marketing, permitirá, por meio de um teste empírico, avaliar e comparar a participação do consumidor nos diferentes tipos de comunidades de marca virtuais gerenciadas pela empresa e gerenciadas pelo consumidor e analisar os resultados comportamentais de marketing de tal participação. Para tanto, utilizou-se um método de pesquisa exploratória/qualitativa como forma de formatar o estudo e elaborar o modelo teórico proposto e as hipóteses de mediação e moderação atinentes ao mesmo. O modelo proposto apresenta contribuições significativas ao estado-da-arte em termos da formulação de novos construtos e de seus relacionamentos, descrevendo-se ainda as potenciais implicações gerenciais resultantes.Pa l a v r a s - C h a v e : Marketing, Comportamento do Consumidor, Marketing de Relacionamento, Comportamento de Comunidades Virtuais.

Exploring the Impact of Financial Development on Inequality: Evidence from Three Asian Countries
Authors: Khan Abdul Qayyum , Hafeez Muhammad Haroon , Saleem Naima , Azam Muhammad 
Published: January 2019

The broad objective of the present study is to investigate the impact of financial development along with some other variables namely GDP per capita, inﬂation rate, human capital, and trade openness for three developing Asian countries- Bangladesh, India and Pakistan. Annual time series data during the period 1980-2014 have been used for empirical investigation. After employing appropriate tests and estimation techniques, it is found that the financial development is statistically insignificant for all three countries, it implies that yet these developing countries are not efficiently allocating domestic private credit to poor segments of population. The results also reveal that inflation impedes income inequality for Bangladesh and India. GDP growth rate is insignificant for India and Pakistan however it is significant for Bangladesh having statistically positive relationship with income inequality. It means that GDP growth rate is linked with growth of income of elite class rather than bottom segments of population. National income improves inequality for Bangladesh but have insignificant affect on income inequality for India and Pakistan. Similarly, trade openness is insignificant for India and Pakistan, however it is significant for Bangladesh having statistically positive relationship with income inequality, which indicates that there is increasing unemployment in these countries due to lesser employment opportunities for skilled and unskilled labour. Empirical results of human capital shows insignificancy for India and Pakistan where as it is significant for Bangladesh; hence revealing that these countries failed to optimally utilize their resources in educational sector.

Published: January 2019

The article analyzes the tax system adopted in the Scandinavian countries - Sweden, Denmark and Norway - in the context of identifying positive behaviors in ensuring optimal fiscal space in Ukraine. The paper outlines some peculiarities of the taxation mechanisms in the selected states and outlines the specifics of their functioning and development. It raises the notion of the dynamics of tax rates differentiation concerning separate taxes in the fiscal practice of the Scandinavian peninsula countries. In the process of studying the tax experience abroad, it was found out that tax burden in Sweden, Denmark and Norway is much higher than that in Ukraine, however, the presence of certain regulatory levers in socially oriented Scandinavian countries shifts tax payments into a real and minimal burden for payers.
The purpose of the article is to carry out a comparative analysis of tax systems of the Scandinavian countries and Ukraine in order to determine the priority directions for formation of an optimal fiscal space of our state.
Methodology. Empirical methods of comparative analysis are adopted to carry out an objective assessment of the fiscal space functioning in the Scandinavian countries and Ukraine. The tax systems differentiation processes are founded on a dialectical method of knowledge.
Conclusions. Tax systems in the Scandinavian countries are characterized by maximum adaptation of the methods for collecting tax payments to the needs of the effective functioning of tax entities and the requirements of modern society, and this could become a positive experience for the optimal fiscal space formation in Ukraine. The tax practice of Sweden, Denmark and Norway proves that the collected taxes are used effectively by the government entities, which allows them to be successfully implemented in a variety of social programs, at the same time providing certain conditions for growth in national business.
