Pérez Vejo,Tomás;
Memoria y Sociedad , 2012,
Abstract: this paper presents an analysis of the theoretical and methodological problems that arise from the use of images as historical documents, as well as some proposals, both theoretical and methodological, to deal with iconic sources in the writing of history.
Historia, antropología y arte: tres sujetos, dos pasados y una sola nación verdadera
Pérez Vejo, Tomás
Revista de Indias , 2012,
Abstract: Analysis of the reorganization of museums carried out by the Mexican State between 1944, the year of the inauguration of the refounded National Museum of History, and 1964, when the Anthropological and Vicerroyal national museums were inaugurated. The narrative of the nation underlying those inaugurations is also analyzed. Análisis de la reordenación museística llevada a cabo por el Estado mexicano entre 1944, inauguración del refundado Museo Nacional de Historia, y 1964, inauguración de los museos nacionales de Antropología y del Virreinato, y del relato de nación que la sustenta.
Los hijos de Cuauhtémoc: el paraíso prehispánico en el imaginario mexicano decimonónico
Tomás Pérez Vejo
Araucaria , 2003,
Abstract: El objetivo de este artículo es reconstruir la forma en que la historia prehispánica fue utilizada por el Estado decimonónico mejicano para construir un imaginario histórico en el que el mito prehispánico-indigenista se convirtió en elemento central de la construcción de la nación. Utilizando como fuente la pintura de historia académica y métodos de análisis de tipo iconológico-estadísticos se describen las principales fases de este proceso, las causas de esta preferencia y las consecuencias que tuvo.

Abstract: The present project is framed in the present tie revisionist line to the period of Independences . As he is already habitual, the commemorations and events mark in a high percentage the scientific calendar and the historiografic production, and now we are immersed as much in the process of the Bicentennials (Hispanic-French War of 1808, American emancipations around the symbolic year of 1810, and You cut of Cadiz in 1812), as in the one to rescue the celebrations of the Centenaries of a century ago. This monographic number tries to add a contribution that could serve as plinth for those who tries an approach to tie subjects with the mentioned historiografic process. In the iconographic construction of the American nations (and national but also not only regional) thematic and the typologies they are from the most varied and each plays a role of major or minor relevance, but always reasonable of a distinguished and global analysis. Of history and social thematic the one in the architecture and the painting, the allegories, the picture, the customs, the landscape case first, sculpture, painting, graph, drawing, photograph, decoratives arts and varied accumulation of objects within second, determine an ample analytical panorama that it has made increase to the interest and the attention of the specialists, mainly of the XIX, with an avidity without comparison with respect to previous decades. El presente proyecto se enmarca en la actual línea revisionista vinculada al período de las independencias . Como ya es habitual, las conmemoraciones y efemérides marcan en un alto porcentaje el calendario científico y la producción historiográfica, y ahora estamos inmersos tanto en el proceso de los Bicentenarios (Guerra hispano-francesa de 1808, emancipaciones americanas en torno al simbólico a o de 1810, y Cortes de Cádiz en 1812), como en el de rescatar las celebraciones de los Centenarios de hace un siglo. Este número monográfico intenta sumar un aporte que pudiera servir de basamento para quienes pretendan una aproximación a temas vinculados con el citado proceso historiográfico. En la construcción iconográfica de las naciones americanas (y no solamente nacionales sino también regionales) las temáticas y las tipologías resultan de lo más variadas y cada una cumple un papel de mayor o menor relevancia, pero siempre plausible de un análisis particularizado y global. El paisaje, las costumbres, el retrato, las alegorías, la pintura de historia y la de temática social en el caso de las primeras, y la arquitectura, escultura, pintura, gráfica, dibujo, foto
Citizenship, Space and Democracy: Political Changes in the Context of Globalization  [PDF]
Gabriel Pérez Pérez
Open Journal of Political Science (OJPS) , 2017, DOI: 10.4236/ojps.2017.71003
Abstract: The article makes a theoretical reflection of space, which has been traditionally studied by geographers and citizenship, without making aside the empirical elements of this relationship. The first paragraph provides that studying the citizenship is necessarily linking it to the issue of democracy, and that, if there have been different approaches for spatial analysis at different scales, we have a diversity of forms and developments that have embraced democracy and citizenship. The second section is central to the theme of the city and it shows how they are given different manifestations and expressions of citizenship that responds to the transformation of public space and the fragmentation of the city. Finally, the third section deals with the theme on how their times currently can observe the emergence of new or different formations citizens. As a consequence of the global transformations, migratory transnational flows or social movements, citizens can be studied through different scales and spaces.
New Evidence on Rotational Dynamics  [PDF]
Luis Alberto Pérez
World Journal of Mechanics (WJM) , 2013, DOI: 10.4236/wjm.2013.33016

In this paper, the author confirmed a new theory to explain the mechanical behavior of macroscopic bodies. The confirmed hypothesis is the Theory of Dynamics Interaction by the Professor Gabriel Barceló. Barceló explained his theory in an article called “Analysis of Dynamics Fields in Noninertial Systems”, World Journal of Mechanics, Vol. 2, No. 3, 2012, pp. 175-180. This hypothesis holds that the mechanical behavior of macroscopic bodies in a non-inertial environment opens new assumptions on inertial fields and rotational dynamics. An associated experiment was presented to support the discussion in the paper. The author first became aware of the proposals of Professor Gabriel Barceló’s Theory of Dynamics Interaction through his 2006 article on Saturn planet rings, which suggested unsolved phenomena in rotational dynamics and the inception of a novel theory [1]. Intuitively, the author realized himself about the fact that the cosmos is mechanical from its smallest to its widest comprehensible appreciation. If material behavior is mechanical everywhere and every time, from a subatomic particle, wave or string, to a cluster of galaxies, then our understandable solutions must comply with the Laws of Motion, it could be believed.

Methodology and Equations of Mineral Production Forecast
—Part I. Crude Oil in the UK and Gold in Nevada, USA. Prediction of Late Stages of Production

Sergio Pérez Rodríguez
Open Journal of Geology (OJG) , 2013, DOI: 10.4236/ojg.2013.35040

The equations of mineral production forecast link the change in time of mineral reserves with the production and the ratio of reserves to production. These equations allow us to model the development of the mineral resources evaluated at any scale. Probabilistic bidimensional charts made from montecarlo simulations provide intervals of confidence for the forecasts. The set of equations is devised and presented for a variety of applications to the oil and gas industry, as well to the production of any other mineral resource, either metals or non metals, whose ore deposit volumes and production might be quantified. The cases studied in the UK and USA are at late stages of production, periods for what the equations are most suitable to be applied without further adjustments. Experimental design allows the diagnosis of the likely values of the variables pertaining to the equations, in order to achieve the results provided by conventional production forecasts or to explore other scenarios of investigation. The method can be practical to evaluate commitments of production of mineral resources with time, to support strategic plans for companies, corporations, countries or regions based on those evaluations, for the screening and ranking of mineral assets based on their production potential and many other tasks where the prediction of future volumes of mineral production is required.

Methodology and Equations of Mineral Production Forecast. Part II. The Fundamental Equation. Crude Oil Production in USA  [PDF]
Sergio Pérez Rodríguez
Open Journal of Geology (OJG) , 2013, DOI: 10.4236/ojg.2013.36044

The fundamental equation of mineral production allows to model and design the dynamics of mineral production, however complex they are or could be. It considers not only the case of a constant production to reserves ratio for given intervals of time, but with a piecewise approach, it is also enabled to account the variation on time of this ratio. With a constant production to reserves ratio, the limit expression of the fundamental equation takes the form of an Erlang distribution with a fixed shape parameter. The rate parameter equals the scale factor. The discrete piecewise version, instead of considering the reserves and the production to reserves ratio being constant through certain intervals of time, updates both variables by units of time. This version, using either lineal or non lineal functions for the variables involved, let to model known production profiles or to forecast them by experimental design. The Hubbert’s linearization updated with recent data and the p-box method applied to determine ultimate recovery of U.S. crude oil reserves indicate official accounts underestimate them. The analysis of the ideal model of production based on Hubbert’s linearization and curve, can be made by decomposing it in the distribution with time of the reserves and of the production to reserves ratio. The distribution of reserves with time is synchronized for both the ideal Hubbert’s curve and real profiles, disregarding whether they match or not. The departure of real profiles from the ideal Hubbert’s curve lies on the differences or correspondences of the distribution with time of the production to reserves ratio. The MonteCarlo simulation applied to forecast US crude oil production for the next five years points to a slow decline, with average annual yields presenting a difference lower than 10% between the start and the end of the simulation.

Accounting Analysis of Economic Policy of Spain (2012)  [PDF]
Miguel Angel Pérez Benedito
Theoretical Economics Letters (TEL) , 2014, DOI: 10.4236/tel.2014.43035
Abstract: The analysis of economic policy is made through a new methodology using the information provided by businesses to the Bank of Spain. The financial statements are the result of economic and financial transactions in a year and show a behavior that is likely to be measured by applying the Edgeworth’s box for analysis. This means that it is possible to measure the response of firms against market disruptions through an accounting interpretation of the information contained in the financial statements. The indicators obtained through this methodology measure a position taken in the Edgeworth’s box. Consequently, the observations obtained are random and therefore may explain the evolution of the economy of any country.
Pérez Pérez,Cruz;
Estudios pedagógicos (Valdivia) , 1999, DOI: 10.4067/S0718-07051999000100007
Abstract: education for co-existence is becoming a priority in many educational centres, to the extent that they are being overwhelmed by high levels of conflictiveness in the classroom. making it necessary for teachers to equip themselves with new methods and techniques in order to face the problem in a global and precautionary way. in this article i analyze the matter from a curricular point of view, in considering that education for co-existence constitutes a content, or a group of contents concerning attitude, which must be the aim of teaching, learning and evaluation. the proposals for participation are based on four important areas: educative project, climate of democratic participation, class assemblies and learning of rules.
