Acción política y comportamiento de los católicos en España
Authors: Redacción Consejo de
Published: May 2020

El renovado interés por las cuestiones públicas en estos últimos tiempos coincide con el lugar especial que va encontrando la acción política en el mundo cristiano. El compromiso explícito y duradero de muchos cristianos en los procesos de transformación social y en los proyectos de cooperación al desarrollo, es paralelo a la renovación del interés, siempre creciente, que se muestra en el catolicismo evangélico por otro mundo posible. Ésa es la ocasión del editorial. Al hacer nuestra reflexión sobre la acción política y el comportamiento de los católicos en España, pretendemos ofrecer una reflexión aplicada a nuestra actual situación española: la relación real de los partidos políticos con el catolicismo y la presencia y actuación de los católicos en el espacio político. Después de analizar algunos signos de nuestro tiempo y los presupuestos de los que partimos al considerar este tema, el editorial aborda las diferentes formas que tienen los cristianos de acercarse a la política y ensaya una tipología de las mismas. A continuación analizamos las relaciones entre el mundo cristiano y tres ámbitos de la acción política en España: izquierdas, derecha y nacionalismos. Por último proponemos algunos criterios para la acción de los católicos en el espacio político. Creemos que los cristianos deben estar en el mundo de la política, como promotores del compromiso por la justicia, que exige también un tiempo y un espacio para su propia constitución como sujetos eclesiales, personal y comunitariamente capacitados para el compromiso evangélico. Éste es uno de los retos fundamentales planteados en este momento para el mundo cristiano en relación con la acción política.
De los proyectos de cooperación a los procesos de desarrollo a largo plazo
Authors: Ferrero y de Loma-Osorio Gabriel
Published: May 2020

En este artículo se analiza las ventajas y los inconvenientes del enfoque de proyectos, tan extendido en la práctica de las intervenciones de desarrollo y la cooperación internacional, tanto como instrumento de gestión como en el plano metodológico.

En el marco del fenómeno de la “fatiga del donante”, se resaltan las ventajas del enfoque para los donantes en contraste con los efectos no deseados de las intervenciones instrumentadas con proyectos desde la perspectiva de la realidad local donde se desarrollan.

Proponiendo una nueva lectura de los procesos de desarrollo a la luz de los emergentes enfoques sobre el capital social, se plantea la necesidad de superar el enfoque de proyectos con un enfoque alternativo: la planificación y la gestión del desarrollo orientada al proceso.
El seguro de dependencia: una nueva perspectiva del envejecimiento
Authors: Moya Huertos Javier
Published: May 2020

Aunque no siempre, con frecuencia los ancianos están sometidos a una situación de dependencia, que requiere una atención especializada y costosa. Ello plantea sobre todo la cuestión de cómo financiar el gasto que conlleva. El presente trabajo constituye un análisis de la situación de la problemática ligada a dicha dependencia, así como una aproximación a las soluciones que han ofrecido a dicho problema, mediante diversas fórmulas de seguro de dependencia, algunos países de nuestro entorno europeo. El autor piensa que todo parece indicar que nuestro país optará por un modelo mixto (público–privado) de seguro de dependencia, inspirado en el modelo alemán, con una importante cartera de servicios prestados a través de la Seguridad Social y que admitirá la complementariedad de los seguros privados, a los que se primaría mediante importantes deducciones fiscales.
Apoyo al desarrollo rural en Vietnam: un caso de investigación–acción
Authors: Amador Hidalgo Francisco
Published: May 2020

El objetivo de este trabajo consiste en describir un proyecto de cooperación al desarrollo en Vietnam, que desde hace dos años, viene realizando un equipo de profesores de INSA–ETEA bajo la dirección del autor, en colaboración con la ONG Acción, Intercambio y Desarrollo de Asia (AIDA) y cofinanciado por la Agencia Española de Cooperación al Desarrollo (AECI). En primer lugar se analiza la filosofía “peculiar” que inspira un proyecto por procesos. En segundo lugar se describe cómo se ha puesto en práctica esta perspectiva para unas determinadas circunstancias institucionales, económicas y culturales. Por último se realiza un balance provisional de los logros obtenidos y se formulan las actuaciones que van a desarrollarse proximamente.

Economía mundial:
Authors: Redacción Consejo de
Published: May 2020

El editorial parte de la idea de que la situación actual de la economía mundial se puede definir con la palabra incertidumbre. Como causa de la incertidumbre se cita en primer lugar el proceso de globalización, que se inicia en los años ochenta y que se puede explicar por tres fenómenos: la política de apertura de la economía norteamericana, el fin de la Guerra Fría y la revolución de las tecnologías de la información. La segunda causa se refiere a la incógnita sobre las consecuencias globales de la hegemonía norteamericana, que recientemente se ha manifestado en la guerra de Iraq y en la nueva situación en Oriente Próximo. Por último, se señala que los científicos sociales no tienen un modelo completo que explique las implicaciones de las acciones humanas; no disponen, por ejemplo, de una teoría de la globalización ni de las relaciones política–económicas, lo que crea también un clima de incertidumbre.
Los resultados de la globalización 1980–2000:
Authors: Weisbrot Marck , Baker Dean , Kraev Egor , Chen Judy
Published: May 2020

Se acepta comúnmente que el incremento de la apertura al comercio internacional y a los flujos financieros, que se ha producido en la inmensa mayoría de los países del mundo, ha conocido un éxito global. El presente artículo contempla los principales indicadores económicos y sociales (ingreso per capita, esperanza de vida, mortalidad infantil y de adultos, tasa de alfabetización y educación) en los países con datos disponibles, y compara los últimos 20 años de globalización (1980–2000) con los 20 años anteriores (1960–1980). Tanto en lo que respecta al crecimiento económico como a casi todos los demás indicadores, los últimos 20 años han mostrado un claro descenso en el progreso en comparación con las dos décadas anteriores. En cualquier caso, no hay evidencia en estos datos de que las políticas asociadas a la globalización hayan mejorado los logros de los países en desarrollo. Como mínimo, la carga de la prueba estaría de lleno del lado de aquellos que pretenden que dichas políticas han sido exitosas.
Aproximación al pensamiento económico de la escolática tardía a través del cardenal Juan de Lugo, S.J.
Authors: Monsalve Serrano Fabio
Published: May 2020

El presente trabajo se centra en el pensamiento económico del escolático español del S. XVII Juan de Lugo –El Doctor Hispalense– y sus teorías sobre el precio justo, el dinero y el interés.La teoría del Justo Precio se articula en torno a cinco elementos diferentes: justicia, teoría subjetiva del valor, estimación común, precios legales y naturales y restitución. Todos ellos conforman un todo coherente como teoría explicativa de los precios.En relación con el pensamiento monetario se muestra la doble concepción del dinero como simple moneda y como capital (herramienta del mercader). También se analiza el problema del doble valor de las monedas: natural (cantidad y calidad del metal) y legal (acuñación).En relación con el análisis sobre la usura, se recogen los principales argumentos esgrimidos por Juan de Lugo para su condena. Estos argumentos no derivan de un presupuesto moral a priori, sino de la visión escolástica del derecho natural y de la concepción del dinero, del tiempo y del contrato de préstamo o mutuo.
Algunos problemas de la actividad financiera desde una perspectiva ética
Authors: López Martín María del Carmen , Rodero Franganillo Adolfo
Published: May 2020

En los últimos tiempos ha sido frecuente la aparición de escándalos, sobre todo en el campo de la actividad financiera, que han alarmado a los ahorradores, especialmente a los titulares del pequeño ahorro, que ven como sus recursos sufren un deterioro y un riesgo de ser tratados de forma injusta por los poderosos de las finanzas.En este escrito se tratan de sistematizar los sucesos más sonados de los últimos años, así como de exponer las iniciativas no muy frecuentes de limitación de las acciones más o menos fraudulentas. Entre otros, nos referimos a fenómenos como: la información privilegiada en los mercados financieros; los consejos interesados de los asesores fiscales; las pérdidas de los fondos de inversión de alto riesgo; los paraísos fiscales y las dificultades de armonización fiscal en la UE; los comportamientos “dudosos” de las entidades financieras; los privilegios de los altos cargos del sistema bancario; el blanqueo de dinero; las cláusulas abusivas de las entidades bancarias; la especulación en los mercados financieros; los informes de los auditores. En cuanto a las medidas correctoras, apuntamos las siguientes: la reforma de los mercados financieros; el informe Aldama; las organizaciones de consumidores y usuarios; las medidas de solvencia; los fondos éticos y solidarios.

RESEARCHING FOR THE SAMPLING METHOD ON CMM
Authors: Thai Ha Thi Thu , Dinh Thang Duc
Published: May 2020

Accurate dimensional inspection and error analysis of free-form surfaces requires accurate registration of the component in hand. Registration of surfaces defined as non-uniform rational B-splines (NURBS) has been realized through an implementation of the iterative closest point method (ICP). The paper presents performance analysis of the ICP registration method using Monte Carlo simulation. A large number of simulations were performed on an example of a precision engineering component, an aero-engine turbine blade, which was judged to possess a useful combination of geometric characteristics such that the results of the analysis had generic significance. Data sets were obtained through CAD (computer aided design)-based inspection. Confidence intervals for estimated transformation parameters, maximum error between a measured point and the nominal surface (which is extremely important for inspection) mean error and several other performance criteria are presented. The influence of shape, number of measured points, measurement noise and some less obvious, but not less important, factors affecting confidence intervals are identified through statistical analysis.

SYNTHESIS AND STORAGE OF SINGLE PHENYLTIN COMPOUNDS SYNTHESIZED FROM ISOTOPICALLY ENRICHED TIN METAL
Authors: Dong Van Nguyen , Frech Wolfgang , Tesfalidet Solomon
Published: May 2020

A method combining liquid liquid extraction and chromatographic fractionation has been developed for the preparation of pure monophenyltin (MPT), diphenyltin (DPhT), and triphenyltin (TPhT), synthesized from isotope enriched Sn-metal using phenylation of SnI4 in diethylether (DEE) followed by quenching with HBr and water. After two successive extractions of the aqueous HBr phase with DEE, more than 99% of the DPT and TPhT were recovered in the combined DEE phase and 94% of the MPT remained in the aqueous phase. The MPT in the aqueous phase was extracted into dichloromethane. The organic phases were vaporised and the PhTs were re-dissolved in MeOH/water/acetic acid/sodium acetate (59/30/6/8, v/v/v/w), which was also used as storing solution. Aliquots of the two solutions containing either DPhT and TPhT or MPhT were injected into a silica based C18 column for isolating and purifying single species. The yield of the purification of MPhT, DPT, and TPht was better than 99%. At -20 °C, all the fractionated phenyltin species were stable in the storing solution for at least 197 days. When these standards were stored at 4 °C or 22°C, 4% to 6% of DPhT and TPhT degraded during 27 days. The degradation of DPT and TPht increased with the ionic strength and acidity of the storage solution.

In some cases, an adaptation of these tests could be required.
HOW ACCURACY GPS PRECISE POINT POSITIONING CAN BE ACHIEVED?
Authors: Nguyen Lau Ngoc
Published: May 2020

We estimate the accuracy of GPS point positioning when using the most recently IGS products and applying the newest IERS models of station displacements. The processing results on 9 IGS stations show that accuracies of 5 mm in the horizontal and 10mm in the vertical can be achieved when processing 24h of static data, and about 10 cm when processing 24h of kinematic data. These accuracies make us to re-consider capabilities and new applications of GPS point positioning.

AN OPTIMAL METHOD FOR SCHEDULING CONSTRUCTION PROJECTS INCLUDING REPETITIVE ACTIVITIES IN MANY UNITS
Authors: Luong Long Duc
Published: May 2020

This paper presents an optimal method for scheduling construction projects including many repetitive activities in many similar units (e.g., high-rise bridges...). The objective of scheduling is to minimize the project duration. This method considers many types of activities with different characteristics (activities must be performed continuously to insure the continuity in their performances, or activities can allow interruptions in their performances) to generate a satisfactory schedule for project managers. This method uses a new scheduling algorithm to find the optimal start and finish times of activities, so that the project duration is minimized. A well-known example is used as an illustration to show advantages of this method to other methods.

SIMULATION OF WAVE PRESSURE ON A VERTICAL WALL BASED ON 2-D NAVIER-STOKES EQUATIONS
Authors: Nguyen Thao Danh , Nguyen Duy The
Published: May 2020

This paper applies and develops a numerical model based on the two-dimensional vertical Navier-Stokes equations to simulate the temporal and spatial variations of wave parameters in front of vertical walls. A non-uniform grids system is performed in the numerical solution of the model by transforming a variable physical domain to a fixed computational domain. Through present model, beside some basic hydrodynamic problems of water waves such as wave profile and water particle velocities, standing wave pressures at the wall are examined. Numerical results of the present model are compared with laboratory data and with existing empirical and theoretical models. The comparisons show that the model can simulate reasonably the wave processes of the waves in front of vertical walls as well as the wave pressures on the wall.

New problems of eventreleted digital management of economics and state
Authors: Solozhentsev E. D.
Published: May 2020

We introduced new structurally complex objects of management in economics and State. We proposed new problems with logical-probabilistic (LP) risk models for managing different types of systems: socio-economic, with risk models based on statistical data, with a large number of indicators and logical combination of several systems.

The following problems are considered in detail: managing the development of systems, assessing the quality of management systems, managing a safe living space, taking into account the effect of repeated events on the accuracy of assessing the safety and quality of a system, planning development programs for complex systems with different subsystem outcomes.

Calculations on LP-model of State set, what reforms are needed in economics. The role of the digital economics in the active inclusion of the personnel of state institutions, enterprises, companies and every person in managing of State and economics is shown.

Authors: Emelyanova V. A.
Published: May 2020

Every year the relevance of the problems of reducing the technological risk of not only a dangerous facility, but also of the region where it is located, the solution of which will reduce both the risk indicators of emergency situations and the extent of their consequences, is growing more and more. Effective implementation of this direction is possible only with the coordination of the activities of state authorities and the responsibility of the owners of such objects. The paper analyzes the occurrence of emergencies associated with the operation of a gas filling station, developed possible scenarios for their development, calculated the damaging factors with the construction of a "tree of events". Assessment of basic risks is the basis for making objective management decisions that ensure the safe and sustainable development of the economy and territorial entity as a whole.

A New Science for a Post-Frontier World
Authors: Worster Donald
Published: May 2020

migrants from Europe and their offspring, competing against the indigenous people and eventually replacing them. But those waves were backed up by the power of the American and Canadian nation states, with their well-armed military, their well funded railroads, and other technology and capital. Science too was initially on the side of the invaders. But after World War One that frontier began to run out of free, abundant land. Then began what I will call a “post-frontier” science, especially ecological in content, that represented a very different attitude toward the white man’s conquest. Scientists like Frederick Clements, John C. Weaver, Paul Sears, and Stan Rowe, all natives to the Great Plains, laid the foundations for what is now a powerful critique of frontier agriculture. My contribution to the panel will summarize that critique briefly but focus mainly on the more recent work of Wes Jackson, founder and longtime president of the Land Institute. He has strongly criticized the frontier ethos for its the lack of understanding of the native ecology of the grasslands. In its place he has offered a vision of “perennial polyculture,” using nature as a model for agriculture in an era of limits. That model has not only been making a growing impact on American thinking but has now spread to other continents. Will the end of this frontier cycle and scientific reappraisal turn out to be what Jackson calls a “new agriculture,” one based on learning from the past and one that can change farming all over the world?
