Hedging foreign exchange rate risk: Multi-currency diversification
2016
Abstract This article proposes a multi-currency cross-hedging strategy that minimizes the exchange risk. The use of derivatives in small and medium-sized enterprises (SMEs) is not common but, despite its complexity, can be interesting for those with international activities. In particular, the reduction in the exchange risk borne through the use of natural multi-currency cross-hedging is measured, considering Conditional Value-at-Risk (CVaR) and Value-at-Risk (VaR) for measuring market risk instead of the variance. CVaR is minimized using linear programmes, while a multiobjective genetic algorithm is designed for minimizing VaR, considering two scenarios for each currency. The results obtai…
Stochastic debt sustainability analysis for sovereigns and the scope for optimization modeling
2017
We express the opinion that sovereign debt sustainability analysis must be augmented by stochastic correlated risk factors and a risk measure to capture tail effects. Crisis situations can thus be adequately specified and analyzed with sufficient accuracy to warrant the relevance of policy decisions. In this context there is significant scope for optimization modeling for both strategic planning and operational management. We discuss diverse aspects of the problem of debt sustainability and highlight modeling approaches that can be brought to bear on the problem. Results with the fictitiuous, but nor unrealistic, Kingdom of Atlantis, which is sinking under excessive debt, illustrate the pro…
5 - 6 gadu vecu bērnu iztēles sekmēšana vizuālās mākslas nodarbībās pirmsskolā
2018
Kvalifikācijas darba tēma: „5 – 6 gadu vecu bērnu iztēles sekmēšana vizuālās mākslas nodarbībās pirmskolā”. Darba mērķis: izpētīt 5 līdz 6 gadu vecu bērnu iztēles pilnveides iespējas vizuālās mākslas nodarbībās pirmskolas izglītības iestādē. Bērna iztēli un radošumu, bērna neatkārtojamību ir nepieciešams attīstīt, nevis apslāpēt, līdz ar to, pedagoģiskajā procesā svarīgi ir nenoteikt stingrus stereotipus, nenovilkt robežas, īpaši mākslas jomā, ir jāpielieto netradicionālas metodes, jāļauj bērniem izpausties. Iztēle ir dota katram bērnam jau no dzimšanas, bet tā ir pasīvā formā, līdz ar to, attīstama. Bērna iztēli var veicināt, attīstīt lasot bērnam pasakas, dziedot ,klausoties dziesmas, spē…

Optimal portfolio allocation with real assets : a Finnish perspective
2017
Alternative market assets, i.e. those which are not part of the ''traditional'' financial assets, have become increasingly popular globally during the last decade. The purpose of this study is to examine the potential benefits of including real investment assets, specifically timberland and real estate holdings, for a investor investing to either domestic or international markets. Specifically the questions to be asked are: Do Finnish real investment assets offer diversification benefits in respect of increased risk-adjusted returns? What are the optimal asset allocations? The analyzed time-series for alternative investments represent quarterly total returns of average Finnish timberland an…
La Ortopantomografía como método para la detección de las placas de ateroma calcificadas: Revisión de la literatura
2006
Los accidentes cerebrovasculares (ACV) constituyen la tercera causa de muerte en los países industrializados, tras la cardiopatía isquémica y el cáncer. Se trata pues de un importante problema de Salud pública, no sólo por su elevada incidencia, sino también por el alto costo que genera la rehabilitación física y psicológica de estos pacientes. El Odontoestomatólogo, como profesional de la salud, debe implicarse ante esta situación y contribuir, dentro de sus posibilidades, a la detección precoz de los pacientes con riesgo de sufrir un ACV. Desde la década de los ochenta, distintos autores han descrito la posibilidad de detectar las placas de ateroma calcificadas localizadas en la bifurcaci…

Phenotypic and genetic characterization of emerging trematodiasis: Fascioliasis and Schistosomiasis
2021
La Fascioliasis y la Esquistosomiasis son dos importantes trematodiasis (re)emergentes con gran impacto en la salud humana. Dada la necesidad de caracterizar las poblaciones de Trematodos involucradas, los objetivos de la presente investigación son: en primer lugar, analizar el impacto de la reinfección experimental por Fasciola hepatica en los fenotipos inmunológicos, clínicos y biológicos por medio de un diseño experimental que reproduce las condiciones habituales de reinfección/cronicidad en las zonas endémicas de la Fascioliasis humana; en segundo lugar, la caracterización fenotípica morfológica de huevos de Schistosoma haematobium de migrantes subsaharianos con Esquistosomiasis urogeni…
