Bayesian semiparametric long memory models for discretized event data
2020
We introduce a new class of semiparametric latent variable models for long memory discretized event data. The proposed methodology is motivated by a study of bird vocalizations in the Amazon rain forest; the timings of vocalizations exhibit self-similarity and long range dependence. This rules out Poisson process based models where the rate function itself is not long range dependent. The proposed class of FRActional Probit (FRAP) models is based on thresholding, a latent process. This latent process is modeled by a smooth Gaussian process and a fractional Brownian motion by assuming an additive structure. We develop a Bayesian approach to inference using Markov chain Monte Carlo and show g…
Management Maps of Chilean Listed Companies. Quantitative Analysis
2017
Este artículo evalúa las clases de gestión adoptadas por las empresas localizadas en la región de Las Condes (Chile) a través de la metodología contable de los gráficos radiales. Esta metodología aplicada sobre dos empresas que utilizan dos diferentes clases de gestión, justifica las relaciones que existen entre los indicadores radiales y financieros. Los resultados contrastados con los precios de las acciones de las empresas analizadas en el mercado secundario confirman la validez de las relaciones anteriores. El análisis realizado ha permitido obtener generalizaciones sobre las distintas clases de gestión en la comuna de Las Condes, de acuerdo con el sentido multidimensional de los gráfic…
The Accounting Maps of Management of Chilean Listed Companies: Qualitative Analysis
2017
El artículo analiza las clases de gestión realizadas por las empresas cotizadas chilenas localizadas en los espacios administrativos de Chile. La orientación del análisis realizado considera que el factor cultural de la región donde están localizadas las empresas chilenas condiciona la clase de gestión desarrollada por dichas empresas. El desarrollo de esta hipótesis se realiza aplicando la metodología contable de los gráficos radiales. Las tensiones existentes entre los periodos medios de maduración representados en un gráfico radial asumen la existencia de un factor cultural en las transacciones realizadas por las empresas en una región y supone que la toma de decisión en un área tiene ef…
Rethinking exchange and prices
2017
Our monetary economies of production are not based upon relative exchanges described by the standard theory. Money is neither a commodity nor a positive asset; it cannot be exchanged against physical goods and services. It follows that payments do not consist of mutual transfers of commodities. In fact, each producer working for the needs for the community produces wealth for himself. Further, transactions on any markets are absolute exchanges. One of the consequences of this is that market prices do not measure wealth; rather, they are coefficients of redistribution of products.
Was Frank Knight an institutionalist?
2005
This paper critically examines Geoffrey Hodgson's recent provocative claim about Frank Knight as being a member of American institutionalism in the interwar years. In the first section of the paper the authors attempt to provide a definition of institutionalism and to emphasize its meaning from a historiographic point of view. The second and third sections analyze the two main methodological struggles between Knight and the institutionalists, namely, the debate during the early 1020s over the use of instinct theory as an explanation of economic behavior, and the subsequent campaign led by Knight in the late 1920s and early 1930s against the behaviorist wing of American institutionalism à la…
Brief History of Computer Art and New Media Art in Latvia
2011
The Soviet and particularly Latvian computer art is not a well-known topic of digital art history. This paper attempts to analyze this computer art in context of the 20th century art, considering the political circumstances in Soviet Union. At the turn of the 21st century after gaining the independence new media art examples and collaboration between scientists, computer scientists, software programmers and the artists are to be found in Latvia. Some recent media art events are mentioned from this viewpoint.
Estudio y análisis de los métodos de iniciación a la viola más utilizados por el profesorado de las Enseñanzas Elementales de la provincia de Valencia
2015
El presente artículo estudia los métodos de iniciación a la viola más utilizados entre el profesorado de las Enseñanzas Elementales de la provincia de Valencia. Participan en el estudio 26 profesores de 21 conservatorios públicos. El instrumento de recogida de la información ha sido el cuestionario diseñado según criterios basados en la sencillez, precisión y concreción de los 32 ítems que lo componen y la discreción y preservación del anonimato en el manejo de la información recabada. La metodología de la investigación ha sido mixta. Se ha utilizado una estrategia de complementación que combina métodos de ambas orientaciones, cuantitativa y cualitativa, ocupándose las distintas perspectiva…
Meta-action research with pre-service teachers: a case study
2014
This article analyses a case of action research collaboratively conducted by a university teacher and 50 students in a master's course in teacher training. Its originality resides in the socio-economic, academic, and conceptual nature of the obstacles encountered in the module; in the meta-theoretical orientation of the action research that was chosen to overcome them; and in how triangulation strategies were devised to compensate for the limitations imposed by the academic framing of the course. In spite of the brevity of the research cycle, both the structure of the course and teacher-student interaction improved rapidly and significantly, as did the latter's trust in the teacher. As a re…
Analysis of Relationship between Net Wage and Consumer Price Index
2013
Abstract In the present paper is presented an econometric analysis of the relationship between net salary and consumer price index. After a brief historical overview will be review the calculating statistics for selected variables and coefficients and will be presented the obtained values. We will study the relationship between variables. It will be realized the cloud of points and will be applied Fisher test. The intensity of selected variables will be study too and some forms of relationship between the two chose variables will be done. Student test is applied. It will be performed the parameter estimation for regression functions and Akaike's criterion will be applied. The homoscedastici…
Identity and socio-educational responsibilities of the educational mediator and the intercultural mediator: towards a clarification of functions
2012
El presente artículo reconoce que, ante la creciente presencia en escenarios socioeducativos de la figura profesional del mediador en los dos ámbitos principales relacionados con la educación (el escolar y el intercultural), deben identificarse los rasgos idiosincrásicos de cada uno de ellos, lo que no es óbice para reconocer cómo, a pesar de que existen, en efecto, diferencias en la definición de estos dos modelos de mediación, se evidencian aspectos coincidentes que los vinculan a un tronco común: las competencias y responsabilidades socioeducativas que adquieren cada uno de ellos. Las autoras del artículo aplican la metodología comparada para demostrar ambas realidades compatibles en las…
