Democracy, political risks and stock market performance

2015

We study whether the emerging stock markets’ performance is affected by direct and indirect effects of democracy level and political risk. We argue that the relationship between democracy level and the political risk is parabolic instead of a simple linear relation i.e. there exists a limit in democracy after which the political risk begins to decline and this is reflected in stock prices. Using panel data for 38 emerging markets at yearly frequency and controlling for several domestic and international factors, we find a fairly robust evidence that during the period 2000-2010, this relationship is true and after some threshold, the more democratic countries produce higher returns.

Didactic proposal to change misconceptions about the contribution of the fusion of the ice to the rise in sea level

2020

En la actualidad existen muchos estudios acerca del conocimiento teórico de la población sobre el cambio climático. Los resultados de estos estudios muestran la existencia de confusiones e ideas alternativas respecto a determinados fenómenos y conceptos básicos de gran importancia, las cuales constituyen un serio obstáculo para el aprendizaje en educación ambiental. En este trabajo se analiza una de esas ideas, relacionada con el impacto directo que tiene la fusión del hielo flotante en el aumento del nivel del mar. Concretamente, se muestra una primera aproximación respecto a su extensión y fortaleza entre alumnado de secundaria y profesorado en formación, detallando a su vez una estrategi…

GeoMaTech: Integrating Technology and New Pedagogical Approaches Into Primary and Secondary School Teaching to Enhance Mathematics Education in Hunga…

2015

During the past decades, technology has been becoming an integral part of everyday life and slowly shaping mathematics and science teaching and learning (e.g. Heid & Blume, 2008). Although there have been enormous investments on educational technologies in many countries technology has yet to make a sizable impact on education (e.g. Drijvers et al., 2010). On the one hand students are becoming increasingly proficient users of technology while on the other hand opportunities offered by technologies have still little been utilized. Nevertheless, as technologies are becoming more integrated into education, they are providing new opportunities for pedagogical approaches and classroom organizati…

Analysis of enniatins and beauvericin by LC-MS/MS in wheat-based products

2017

Due to the matrix complexity for wheat-based products, a comparative study of different rapid extraction procedures was performed for the extraction of enniatins (ENA, ENA1, ENB, ENB1) and beauvericin in flour, pasta, breakfast cereals, and biscuits. Three different approaches were studied during the extraction and purification steps (shaker, Ultra-Turrax, and QuEChERS) for each matrix. Liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) with electrospray source working in a positive mode was used. For the analysis of the five mycotoxins, the three methods were tested in terms of recovery, matrix effect, and sensibility, concluding that Ultra-Turrax extraction was the most …

The Italian adaptation and validation of the Adult Sibling Relationship Questionnaire (ASRQ) in Italian emerging adults

2013

The aims of the present study were to provide a contribution to the validation of the Adult Sibling Relationship Questionnaire (ASRQ) (Stocker, Lanthier, & Furman, 1997) with a population of Italian emerging adults. The ASRQ measures individuals’ current perceptions of their own behaviour and feelings toward their sibling, as well as their perceptions of their sibling’s behaviour and feelings toward him or her by assessing fourteen fundamental dimensions (Intimacy; Affection; Emotional Support; Instrumental Support; Knowledge; Similarity; Admiration; Acceptance; Dominance; Competition; Antagonism; Quarrelling; Maternal Rivalry; and Paternal Rivalry), combined in order to form three macro-di…

An Empirical Investigation of Heavy Tails in Emerging Markets and Robust Estimation of the Pareto Tail Index

2021

In this work we analyze and compare the performances of VaR-based estimatorswith respect to three different classes of distributions, i.e., Gaussian, Stable and Pareto, and to different emerging markets, i.e., Egypt, Qatar and Mexico. This is motivated by the evidence that there are points of distinction between emerging and developed markets mainly relating to the speed and reliability of information available to investors.We propose a computational Threshold Accepting-VaR based algorithm (TAVaR) for optimally estimating the Pareto tail index. A Monte Carlo bias estimation analysis is also carried out by comparing our proposed methodology with the Hill estimator and a variant of it.

Greenfield or M&A? An institutional and learning perspective on the establishment mode choice of Chinese outward investments

2020

Abstract We develop and test a model of Chinese greenfield investments using institutional and learning theories. Both the host country institutional context and the firm's international characteristics affect the establishment mode. Using 152 Chinese emerging market multinationals (EMNEs) with 401 subsidiaries distributed in 26 countries from 2003 to 2013, we build a database of 284 pairs of host country/Chinese firms to test two hypotheses. We find that, first, governance environment affects the establishment mode: greenfield investments are preferred over acquisitions in relation-based host markets, and M&As are preferred in rule-based countries. Second, the depth of Chinese EMNEs' inter…

Emerging Market Contagion Under Geopolitical Uncertainty

2019

We find that 10 emerging stock markets have high risk of contagion on the regional level but lower spillover with respect to the global markets, implying a potential for diversification benefits between emerging and global markets. Regional market integration seems to have been caused by trade integration, which has a policy implication for trade agreements’ systemic risk effects. We find that the geopolitical risk has no impact on either the return, or volatility spillovers. However, the general stock market risk (VIX) is connected to individual market volatilities, while the oil market is largely receiving the spillovers from the other markets. peerReviewed

La calidad periodística en España según la percepción de los periodistas

2015

Este artículo expone los resultados de una investigación sobre la percepción que tienen los periodistas españoles de la calidad periodística, teniendo en cuenta el contexto económico, tecnológico, empresarial, laboral y profesional. Los resultados de una encuesta, en la que participan 363 periodistas españoles con al menos tres años de experiencia en diferentes medios, ponen de manifiesto carencias relativas tanto a la relevancia y diversidad de los temas abordados como al acceso a las fuentes o el tratamiento y verificación de los datos, así como a las condiciones laborales o a los retos derivados de la adaptación a las nuevas tecnologías y a las imposiciones de la acuciante inmediatez.
