Medidas de Riesgo Financiero y una Aplicación a las Variaciones de Depósitos del Sistema Financiero Boliviano

This paper describes three measures of financial risk –Value at Risk (VaR) based on the Gaussian distribution, VaR based on extreme value theory and conditional VaR (expected shortfall) – and shows an application of these measures to the withdrawals of deposits in the Bolivian financial system. The results suggest that it’s important to consider the statistical assumptions of these measures, in order to avoid underestimate or overestimate the true financial risks

Designing experiments using digital fabrication in structural dynamics

In engineering, traditional approaches aimed at teaching concepts of dynamics to engineering students include the study of a dense yet sequential theoretical development of proofs and exercises. Structural dynamics are seldom taught experimentally in laboratories since these facilities should be provided with expensive equipment such as wave generators, data-acquisition systems, and heavily wired deployments with sensors. In this paper, the design of an experimental experience in the classroom based upon digital fabrication and modeling tools related to structural dynamics is presented. In particular, all experimental deployments are conceived with low-cost, open-source equipment. The hardware includes Arduino-based open-source electronics whereas the software is based upon object-oriented open-source codes for the development of physical simulations. The set of experiments and the physical simulations are reproducible and scalable in classroom-based environments.Peer ReviewedPostprint (author's final draft

Entrevista con Nicolás Rosa : las pasiones son un objeto inobservable

En esta entrevista se repasan algunas de las ideas centrales desarrolladas por Nicolás Rosa en la\nconferencia inaugural del Congreso. Habló allí sobre la semiótica de las pasiones, que es un tema de\nactualidad absoluta en el campo de los estudios sobre la significación que no ha tenido gran desarrollo\nen la Argentina. Las pasiones constituyen un objeto inobservable, cuando se habla sobre el amor, no\nse hace el amor, cuando se habla sobre el dolor, no se lo cura

Primary Sjögren's Syndrome First Presenting as Hypokalemic Quadriparesis

ABSTRACT Hypokalemic paralysis and respiratory failure associated with distal renal tubular acidosis as first clinical manifestation of primary Sjögren's syndrome has been reported a few times. In this article, we describe the case of a previously healthy 38-year-old female patient who presented to the emergency department with a three-day history of dyspnea at rest and rapidly progressive generalized muscular weakness. Her initial work-up revealed an uncompensated hyperchloremic metabolic acidosis and severe hypokalemia. Additionally, urine pH of 8.0 and other findings consistent with distal renal tubular acidosis were found. We excluded the most common causes of distal renal tubular acidosis and finally established the diagnosis of primary Sjögren’s syndrome. Our patient was treated with potassium citrate and later discharged on this treatment. Keywords: Distal renal tubular acidosis; hyperchloremic metabolic acidosis; hypokalemic paralysis; respiratory insufficiency; Sjögren's syndrome

Market Structure, Entrance Conditions and Optimal Number of Banks in the Bolivian Financial System: A Concentration and Industrial Mobility Indicators Approach

This paper calculates indicators of market structure: concentration ratio, Herfindahl index, Herfindahl-Hirschman index, inverse of the Herfindahl index and the stability indicator. These indicators are used: (1) to measure indirectly the competitiveness of the bank market, (2) to define conditions of entrance of new banks to the market, and (3) to establish a criterion to estimate the optimal number of banks in the market.indicadores de concentración; estructura de mercado; número óptimo de bancos

Synthesis and conformational analysis of leptocarpin derivatives. Influence of modification of the oxirane ringon leptocarpin's cytotoxic activity.

Indexación: ScieloABSTRACT The reaction in acidconditions of Leptocarpin 1, a compound with antitumor activity, formed two new isomeric products, 8b-angeloyl-1b,3b-dihydroxy-4,10-dimethyl,-D11(13) methylen-4Z,9Z-dieneheliangol-6,12-olide 2 and 8b-angeloyl-1b,3b-dihydroxy-4-methyl-D11(13),D11(14)-dimethylen-4Z-eneheliangol-6,12-olide 3, whose structures reported in this study were established by spectroscopy (1H-NMR, 13C-NMR, MS and IR) and confirmedthrough ROESY experiments and theoretical studies by molecular mechanics. The in vitro cytotoxicity of these isomeric compounds was less active than leptocarpin, showing the importance of the oxirane ring in the biological activity. Cytotoxic activity was measured in six cancer cell lines. Keywords: Conformational analysis; Heliangolide; Sesquiterpene lactones; Cytotoxicity

Numerical validation of the incremental launching method of a steel bridge through a small-scale experimental study

The final publication is available at Springer via http://dx.doi.org/10.1007/s40799-016-0037-5This article presents an experimental and a numerical study of an incremental launching process of a steel bridge. The former is deployed in a scale-reduced laboratory,whereas the latter is performed using the finite elementmethod. The numerical simulation is based upon realistic transient boundary conditions and accurately reproduces the elastic response of the steel bridge during launching. This numerical approach is validated experimentally with the scale-reduced test performed at the laboratory. The properly validated numerical model is subsequently systematically employed as a simulation tool of the process. The proposed simulation protocol might be useful for design and monitoring purposes of steel bridges to be launched. Results concerning strains, stresses, and displacements might be inferred from the model and thus compared to field measurements obtained in situ. The conditions presented at the end of the article are potentially useful for researchers and practice engineers alike.Peer ReviewedPostprint (author's final draft

Efectos asimétricos de shocks de inflación e incertidumbre inflacionaria en Bolivia 1990-2013

ResumenEste documento de investigación analiza la evolución de la inflación mensual de Bolivia en el periodo 1990:01 a 2013:03 y presenta evidencia a favor de la hipótesis de Friedman y Ball, la cual establece que altos niveles de inflación incrementan la incertidumbre inflacionaria, y en menor magnitud y significancia también se acepta la hipótesis de Cukierman y Metzler, la cual postula que altos niveles de incertidumbre inflacionaria incrementan la tasa de inflación promedio, al mismo tiempo podemos también afirmar que para el caso de Bolivia no se cumple la hipótesis de Holland, Grier y Perry, la cual afirma que existe una relación inversa entre la incertidumbre inflacionaria y la tasa de inflación y en la misma presupone que la dirección de causalidad va de la incertidumbre hacia el nivel de inflación. Además, se encuentra evidencia de que shocks de inflación positivos tienen un impacto mayor sobre la incertidumbre inflacionaria que shock negativos, y que la incertidumbre inflacionaria tiene una tendencia decreciente a través del tiempo, esta última afirmación producto de la buena labor y desempeño de las autoridades monetarias, para promover la estabilidad de precios y mantener así una macroeconomía con inflación baja.AbstractThis research paper examines the evolution of the monthly inflation of Bolivia in the period 1990:01- 2013:03 and presents evidence for the hypothesis of Friedman and Ball,which states that high inflation increases inflation uncertainty, and to a lesser extent and significance the hypothesis Cukierman and Metzler is also accepted, which postulates that high levels of inflation uncertainty increase the average rate of inflation. At the same time we can also say that in the case of Bolivia not the hypothesis Holland, Grier and Perry, which states that there is an inverse relationship between inflation uncertainty and inflation is fulfilled. In addition, there is evidence that positive inflation shocks have a greater impact on the negative shock to inflation uncertainty, and inflation uncertainty has a decreasing trend over time, this last statement product of good work and performance of authorities monetary, to promote price stability and thus maintain low inflation macroeconomics
