The parallel diplomacy and the International Relations of the regions

The inclusion of subnational entities in international politics, breaks with the exclusive privilege of handling external relations by the States. Regions and municipalities have developed international policies that strengthen local affairs in cultural, economic, politic, security and strategic cooperation aspects, through the so-called parallel diplomacy activities. The influence of regional institutions in global affairs is growing; however paradiplomacy practice is not institutionalized and received little attention in international relation studies.

Trashumancia electoral en los comicios locales de 2003-2007-2011 en Boyacá

El propósito del presente trabajo de grado es determinar la incidencia que tuvo la trashumancia electoral en los comicios locales de 2003-2007-2011 en Boyacá, para la designación de Alcaldes municipales en dichos momentos. De esta manera, se sostiene que el fraude en inscripción de cédulas, como se le conoce al delito, ayudó a llegar al poder a líderes que utilizaron el transporte de votantes como forma de hacerse elegir en cada uno de los territorios en los que aspiraban al cargo. Por ello, se identificaron las inconsistencias existentes entre el crecimiento poblacional mayor de 18 años y el censo electoral de cada uno de los periodos analizados, considerando las diferentes denuncias tanto administrativas como penales, presentadas ante los organismos competentes, así como las percepciones sociales a través del análisis de prensa local. Con esto, se busca dar a conocer una de las consecuencias del fraude en los contextos democráticos.

Decentralization and local government performance improving public service provision in Bolivia.

Este artículo analiza algunas de las justificaciones más importantes para el desarrollo de procesos de descentralización, analiza sus fundamentos teóricos, y posteriormente describe los elementos de una nueva teoría descentralización, la cual debería llevarnos más lejos en nuestro entendimiento de la efectividad y las implicaciones de la descentralización. Finalmente y de forma más importante, revisamos una gran cantidad de nueva información sobre los efectos de la descentralización en Bolivia. Encontramos fuerte evidencia de que la devolución de recursos y poderes a los gobiernos locales han (i) incrementado en la eficiencia de asignación en el sector público boliviano, (ii) generado una mayor estabilidad en los patrones de inversión pública entre sectores, (iii) llevado a un gobierno más orientado a las necesidades locales de lo que había sido posible a través de gobiernos centralizados, y (iv) muy probablemente incrementado el criterio de costo efectividad del sector público.

Espacios locales de participación y construcción de ciudadanía un estudio de caso de la Junta Administradora Local de Teusaquillo

La propuesta de la investigación consiste en observar y comprobar si efectivamente los espacios de participación local surgidos después de la constitución de 1991, en un esfuerzo del estado colombiano y la administración Distrital por descentralizar la función administrativa, han sido efectivos dentro del proceso de construcción de ciudadanía, y en qué forma los ediles interactúan con los habitantes de la localidad y canalizan las demandas de la comunidad. Por lo mismo, se pretende indagar sobre las características de la participación ciudadana en la localidad y la aparición de tensiones entre la apertura de espacios de participación, y el uso de ellos por redes políticas locales de tipo clientelista. De esta forma, se busca comprobar si surge así, un fenómeno de construcción de ciudadanía permeado por intereses de carácter particularista, limitando a los ciudadanos, que como miembros de las redes de intermediación política, acceden a los derechos de ciudadanía que ofrecen los nuevos espacios de representación

Natural resource windfalls and efficiency of local government expenditures: evidence from Peru

We study the role of natural resource windfalls in explaining the efficiency of public expenditures. Using a rich dataset of expenditures and public good provision for 1,836 municipalities in Peru for period 2001-2010, we estimate a non-monotonic relationship between the efficiency of public good provision and the level of natural resource transfers. Local governments that were extremely favored by the boom of mineral prices were more efficient in using fiscal windfalls whereas those benefited with modest transfers were more inefficient. These results can be explained by the increase in political competition associated with the boom. However, the fact that increases in efficiency were related to reductions in public good provision casts doubts about the beneficial effects of political competition in promoting efficiency.

Modelling, control and supervision for a class of hybrid systems

The aim of this thesis is to narrow the gap between two different control techniques: the continuous control and the discrete event control techniques DES. This gap can be reduced by the study of Hybrid systems, and by interpreting as Hybrid systems the majority of large-scale systems. In particular, when looking deeply into a process, it is often possible to identify interaction between discrete and continuous signals. Hybrid systems are systems that have both continuous, and discrete signals. Continuous signals are generally supposed continuous and differentiable in time, since discrete signals are neither continuous nor differentiable in time due to their abrupt changes in time. Continuous signals often represent the measure of natural physical magnitudes such as temperature, pressure etc. The discrete signals are normally artificial signals, operated by human artefacts as current, voltage, light etc. Typical processes modelled as Hybrid systems are production systems, chemical process, or continuos production when time and continuous measures interacts with the transport, and stock inventory system. Complex systems as manufacturing lines are hybrid in a global sense. They can be decomposed into several subsystems, and their links. Another motivation for the study of Hybrid systems is the tools developed by other research domains. These tools benefit from the use of temporal logic for the analysis of several properties of Hybrid systems model, and use it to design systems and controllers, which satisfies physical or imposed restrictions. This thesis is focused in particular types of systems with discrete and continuous signals in interaction. That can be modelled hard non-linealities, such as hysteresis, jumps in the state, limit cycles, etc. and their possible non-deterministic future behaviour expressed by an interpretable model description. The Hybrid systems treated in this work are systems with several discrete states, always less than thirty states (it can arrive to NP hard problem), and continuous dynamics evolving with expression: with Ki ¡ Rn constant vectors or matrices for X components vector. In several states the continuous evolution can be several of them Ki = 0. In this formulation, the mathematics can express Time invariant linear system. By the use of this expression for a local part, the combination of several local linear models is possible to represent non-linear systems. And with the interaction with discrete events of the system the model can compose non-linear Hybrid systems. Especially multistage processes with high continuous dynamics are well represented by the proposed methodology. Sate vectors with more than two components, as third order models or higher is well approximated by the proposed approximation. Flexible belt transmission, chemical reactions with initial start-up and mobile robots with important friction are several physical systems, which profits from the benefits of proposed methodology (accuracy). The motivation of this thesis is to obtain a solution that can control and drive the Hybrid systems from the origin or starting point to the goal. How to obtain this solution, and which is the best solution in terms of one cost function subject to the physical restrictions and control actions is analysed. Hybrid systems that have several possible states, different ways to drive the system to the goal and different continuous control signals are problems that motivate this research. The requirements of the system on which we work is: a model that can represent the behaviour of the non-linear systems, and that possibilities the prediction of possible future behaviour for the model, in order to apply an supervisor which decides the optimal and secure action to drive the system toward the goal. Specific problems can be determined by the use of this kind of hybrid models are: - The unity of order. - Control the system along a reachable path. - Control the system in a safe path. - Optimise the cost function. - Modularity of control The proposed model solves the specified problems in the switching models problem, the initial condition calculus and the unity of the order models. Continuous and discrete phenomena are represented in Linear hybrid models, defined with defined eighth-tuple parameters to model different types of hybrid phenomena. Applying a transformation over the state vector : for LTI system we obtain from a two-dimensional SS a single parameter, alpha, which still maintains the dynamical information. Combining this parameter with the system output, a complete description of the system is obtained in a form of a graph in polar representation. Using Tagaki-Sugeno type III is a fuzzy model which include linear time invariant LTI models for each local model, the fuzzyfication of different LTI local model gives as a result a non-linear time invariant model. In our case the output and the alpha measure govern the membership function. Hybrid systems control is a huge task, the processes need to be guided from the Starting point to the desired End point, passing a through of different specific states and points in the trajectory. The system can be structured in different levels of abstraction and the control in three layers for the Hybrid systems from planning the process to produce the actions, these are the planning, the process and control layer. In this case the algorithms will be applied to robotics ¡V a domain where improvements are well accepted ¡V it is expected to find a simple repetitive processes for which the extra effort in complexity can be compensated by some cost reductions. It may be also interesting to implement some control optimisation to processes such as fuel injection, DC-DC converters etc. In order to apply the RW theory of discrete event systems on a Hybrid system, we must abstract the continuous signals and to project the events generated for these signals, to obtain new sets of observable and controllable events. Ramadge & Wonham¡¦s theory along with the TCT software give a Controllable Sublanguage of the legal language generated for a Discrete Event System (DES). Continuous abstraction transforms predicates over continuous variables into controllable or uncontrollable events, and modifies the set of uncontrollable, controllable observable and unobservable events. Continuous signals produce into the system virtual events, when this crosses the bound limits. If this event is deterministic, they can be projected. It is necessary to determine the controllability of this event, in order to assign this to the corresponding set, , controllable, uncontrollable, observable and unobservable set of events. Find optimal trajectories in order to minimise some cost function is the goal of the modelling procedure. Mathematical model for the system allows the user to apply mathematical techniques over this expression. These possibilities are, to minimise a specific cost function, to obtain optimal controllers and to approximate a specific trajectory. The combination of the Dynamic Programming with Bellman Principle of optimality, give us the procedure to solve the minimum time trajectory for Hybrid systems. The problem is greater when there exists interaction between adjacent states. In Hybrid systems the problem is to determine the partial set points to be applied at the local models. Optimal controller can be implemented in each local model in order to assure the minimisation of the local costs. The solution of this problem needs to give us the trajectory to follow the system. Trajectory marked by a set of set points to force the system to passing over them. Several ways are possible to drive the system from the Starting point Xi to the End point Xf. Different ways are interesting in: dynamic sense, minimum states, approximation at set points, etc. These ways need to be safe and viable and RchW. And only one of them must to be applied, normally the best, which minimises the proposed cost function. A Reachable Way, this means the controllable way and safe, will be evaluated in order to obtain which one minimises the cost function. Contribution of this work is a complete framework to work with the majority Hybrid systems, the procedures to model, control and supervise are defined and explained and its use is demonstrated. Also explained is the procedure to model the systems to be analysed for automatic verification. Great improvements were obtained by using this methodology in comparison to using other piecewise linear approximations. It is demonstrated in particular cases this methodology can provide best approximation. The most important contribution of this work, is the Alpha approximation for non-linear systems with high dynamics While this kind of process is not typical, but in this case the Alpha approximation is the best linear approximation to use, and give a compact representation.

Imágenes locales y retórica sagrada: una visión edificante de Quito en el siglo XVII (Dossier: Historia del Arte)

El artículo analiza la realización entre las imágenes y la oratoria sagrada durante el siglo XVII en Quito. Examina, de un lado, cómo los sermones hacían uso de un canon oficial cristiano para definir y legitimar los cultos religiosos locales, y, de otro lado, las disposicions urbanas de las imágenes milagrosas de la Virgen María, estratégicamente ubicadas en santuarios, constituyendo el paisaje local de una cartografía sagrada. Estos elementos contribuyeron a forjar una visión edificante de la urbe, presentada como una Nueva Jerusalén escogida por Dios. Este gesto aparece ligado con la consolidación de la identidad criolla y el fortalecimiento de un incipiente patriotismo local.

Localismo y miradas urbanas: las monografías locales en el Ecuador del siglo XX (Estudios)

La construcción del Estado nacional involucró la conformación de las localidades y la difusión de los idearios y símbolos nacionales. Las monografías locales transmitieron estos símbolos con el propósito de vincular las patrias chicas a la nación. Las miradas urbanas locales se convirtieron, a menudo, en imágenes del progreso y retratos de las élites locales. El período de mayor producción de estas monografías -1920 y 1960- coincide con el auge de la prensa regional. Esto revela la relativa eficacia con que se propagaron los símbolos patrios durante el período de profundización de la división político-administrativa y la constitución de los poderes locales en el Ecuador.

Rapid parallel expression in E-coli and insect cells: Analysis of five lef gene products of the Autographa californica multiple nuclear polyhedrosis virus (AcMNPV)

A number of strategies are emerging for the high throughput (HTP) expression of recombinant proteins to enable structural and functional study. Here we describe a workable HTP strategy based on parallel protein expression in E. coli and insect cells. Using this system we provide comparative expression data for five proteins derived from the Autographa californica polyhedrosis virus genome that vary in amino acid composition and in molecular weight. Although the proteins are part of a set of factors known to be required for viral late gene expression, the precise function of three of the five, late expression factors (lefs) 6, 7 and 10, is unknown. Rapid expression and characterisation has allowed the determination of their ability to bind DNA and shown a cellular location consistent with their properties. Our data point to the utility of a parallel expression strategy to rapidly obtain workable protein expression levels from many open reading frames (ORFs).
