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.
Transformation of the Political Theory: Cosmopolitan Citizenship and Democracy  [PDF]
Gabriel Pérez Pérez
Open Journal of Political Science (OJPS) , 2019, DOI: 10.4236/ojps.2019.92018
Abstract: This paper is concerned with the topic of cosmopolitan citizenship and its relation to democracy. We begin by highlighting the main postulates of Kantian cosmopolitanism, as many theorists Kant contributes an idea of cosmopolitan citizenship linked to the need to establish international political institutions that support citizenship beyond an exclusively moral dimension. We then discuss the issue of the transformation undergone by the nation state in the context of globalization, particularly the loss of sovereignty of the state and the growth of multinational companies, and how these changes have come to set a new scenario for the emergence of international actors and the basis for various citizenship practices in a cosmopolitan dimension. The nature and current reach of cosmopolitan citizenship is explored through two fundamental cases: the European Union, and ecologic citizenship. Finally, we discuss cosmopolitan democracy and which ought to be its characteristics, among which we identify the establishment of supranational political institutions, the consolidation of a global civil society, and the establishment of mechanisms for citizen participation beyond the traditional ones situated in the national sphere.
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

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.

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.

Abstract: Resumen Frente al propósito de disminución del déficit habitacional del país, la figura del arrendamiento cobra importancia como herramienta que, además de contribuir de manera directa a su disminu-ción, puede llegar a constituir una opción de inversión rentable. Adicionalmente, en un contexto caracterizado por limitaciones fiscales del estado, precariedades de las viviendas existentes, difi-cultades en el acceso a créditos hipotecarios e ineficiencia en la gestión urbana, entre otras, el arrendamiento se convierte en una alternativa de solución habitacional, en el corto plazo, para los hogares más pobres. Por lo anterior, la investigación adelantada responde a la necesidad de caracterizar el mercado de arrendamiento urbano, enfocado en el segmento de población más pobre. Buscando identificar las posibilidades de articular estos mercados en un marco formal que posibilite su interrelación con instrumentos financieros que apalanquen la oferta de vivienda en arriendo, para los estratos bajos de la población. Abstract Given the aim of decreasing Colombia’s housing shortage, the possibility of renting is important as a tool that, in addition to contributing directly to the reduction of housing shortage, can be a profitable investment option. Additionally, in a context of fiscal constraints at national level, poor conditions of existing homes, difficult access to mortgages and inefficiency in public administration at municipality level, among other aspects, renting is an alternative short term solution for the poorest. The present research was carried out in order to respond to the need for a characterization of the urban rental market, focusing on the poorest segment. It seeks to identify the possibilities of fitting these markets in a legal framework that enables their interaction with financial instruments, so that the supply of rental housing for the lower strata of the population can be stimulated.

El modelo federal de la Unión Europea
Gabriel Pérez Pérez
El Cotidiano , 2009,
Abstract: El artículo analiza las dos características básicas del proceso de integración federal de la Unión Europea. La primera es el "Federalismo Económico", por sus principios basados en los postulados del libre mercado y la unificación monetaria; aunado a esto, y en segundo lugar, se ha desarrollado también un modelo de "federalismo intergubernamental" que busca darle a la Unión Europea un tipo de integración más social y política, el cual actualmente se encuentra con una gran incertidumbre debido al rechazo de la Constitución Europea.
