A BARGAINING APPROACH TO COORDINATION IN NETWORKS
This paper presents a model in which players interact via the formation of costly links and the benefits of bilateral interactions are determined by a coordination game. A novel contribution of this paper is that the fraction of the cost borne by each player involved in a bilateral link is not fixed exogenously, but results from bargaining. We analyze the model both in a static and a dynamic setting. Whereas the static game has multiplicity of equilibria, we show that only one is stochastically stable.Coordination; Nash bargaining solution; Risk-dominance; Stochastic stability
NETWORK FORMATION AND COORDINATION: BARGAINING THE DIVISION OF LINK COSTS
This paper presents a model of network formation with costly links. We endogenize the amount of cost born by each player involved in a bilateral link by considering that these shares result from bargaining. We analyze this feature in a context of coordination games. We show that, if the cost of the link is not too high, the complete network arises and players coordinate on the same action. If this cost is higher than the risk-dominance premium the efficient action is selected; instead, if it is lower, the risk-dominant action prevails.Coordination, Nash bargaining solution, Markov process
Voting in small networks with cross-pressure
We present a model of participation in elections in small networks, in which citizens su¤er from cross-pressures if voting against the alternative preferred by some of their social contacts. We analyze how the existence of cross-pressures may shape voting decisions, and so, political outcomes; and how candidates may exploit this e¤ect to their interest.Network; Voting; Cross-Cutting.
Resistance to learning and the evolution of cooperation
In many evolutionary algorithms, crossover is the main operator used in generating new
individuals from old ones. However, the usual mechanism for generating offsprings in spatially
structured evolutionary games has to date been clonation. Here we study the effect of
incorporating crossover on these models. Our framework is the spatial Continuous Prisoner's
Dilemma. For this evolutionary game, it has been reported that occasional errors (mutations) in
the clonal process can explain the emergence of cooperation from a non-cooperative initial
state. First, we show that this only occurs for particular regimes of low costs of cooperation.
Then, we display how crossover gets greater the range of scenarios where cooperative mutants
can invade selfish populations. In a social context, where crossover involves a general rule of
gradual learning, our results show that the less that is learnt in a single step, the larger the
degree of global cooperation finally attained. In general, the effect of step-by-step learning can
be more efficient for the evolution of cooperation than a full blast one
Diagnóstico y optimización de la PTAP del municipio de Fómeque (Cundinamarca)
Trabajo de InvestigaciónEl presente trabajo tiene como objeto analizar y describir la planta de tratamiento
de agua potable del municipio de Fómeque (Cundinamarca) ubicada en la vereda
el Mortiñal, cuenta con las siguientes estructuras hidráulicas: una canaleta
parshall, un dosificador de sulfato de aluminio, un desarenador, un pre –
sedimentador, cuatro floculadores, un sedimentador, cuatro filtros rápidos, cuatro
tanques de almacenamiento, un tanque de salida, cuenta con laboratorio de dos
pisos.
Se realizaron laboratorios de caracterización del agua problema obtenidas de la
bocatoma, entrada, salida y domiciliaria, con el fin de evaluar y compararla con la
Resolución 2115 del 2007. Se realizó la prueba de test de jarras con el fin de
obtener la dosis de coagulante (sulfato de aluminio tipo A) óptimo para brindar la
formación del floc y obtener agua apta para el consumo humado posteriormente
del proceso de tratamiento en la PTAP.INTRODUCCIÓN

Bounded Confidence under Preferential Flip: A Coupled Dynamics of Structural Balance and Opinions
In this work we study the coupled dynamics of social balance and opinion
formation. We propose a model where agents form opinions under bounded
confidence, but only considering the opinions of their friends. The signs of
social ties -friendships and enmities- evolve seeking for social balance,
taking into account how similar agents' opinions are. We consider both the case
where opinions have one and two dimensions. We find that our dynamics produces
the segregation of agents into two cliques, with the opinions of agents in one
clique differing from those in the other. Depending on the level of bounded
confidence, the dynamics can produce either consensus of opinions within each
clique or the coexistence of several opinion clusters in a clique. For the
uni-dimensional case, the opinions in one clique are all below the opinions in
the other clique, hence defining a "left clique" and a "right clique". In the
two-dimensional case, our numerical results suggest that the two cliques are
separated by a hyperplane in the opinion space. We also show that the
phenomenon of unidimensional opinions identified by DeMarzo, Vayanos and
Zwiebel (Q J Econ 2003) extends partially to our dynamics. Finally, in the
context of politics, we comment about the possible relation of our results to
the fragmentation of an ideology and the emergence of new political parties.Comment: 8 figures, PLoS ONE 11(10): e0164323, 201
The building of a modern district seen from the perspective of its open spaces: Huerta del rey (Valladolid)
Huerta del Rey es un barrio residencial de Valladolid “de bloques y torres” en el que se han ido superponiendo en distintos estratos los puntos doctrinales del Movimiento Moderno, las expectativas del Ayuntamiento y las transformaciones que han hecho sus habitantes de este espacio, en un proceso que se dilata desde mediados hasta finales del siglo XX. Fruto de tal proceso, unas veces controlado y otras fortuito, su espacio libre ha ido adquiriendo espesor y carácter. Aunque la valoración actual del barrio
no es unánime, frente a la agresividad de que se suele acusar hoy a los espacios libres de propuestas materializadas de forma rigurosa desde postulados de la Carta de Atenas, éste ha conseguido adquirir una gran coherencia formal y social. El artículo evidencia a partir de la historia urbanística del barrio el carácter paralelo de las diversas concepciones institucionales, sociales y disciplinares, que se han cernido sobre él y la contribución de cada una de ellas en la resultante final, que no definitivaHuerta del Rey is a residential district of Valladolid comprising tower blocks and high-rise buildings. In it the doctrines of the Modernist Movement, the expectations of the City Council and the adjustments made by those living in the area have gradually been superposed in different strata. This was a process that ran over the period from the middle of the twentieth century through until its end. As an outcome of this process, sometimes controlled, sometimes haphazard, its open spaces have gained depth and character. Although current assessments of the district are not unanimous, it has managed to achieve considerable formal and social coherence, in contrast with the aggressiveness which nowadays is attributed to the open spaces established by projects slavishly following the guidelines of the Athens Charter. This paper gives evidence from the town-planning history of the district to show the parallel nature of the various institutional, social and disciplinary concepts that have been applied to it and the contribution made
by each to the final, though not definitive, resul
