    A Model of Emotion as Patterned Metacontrol

    Get PDF
    Adaptive systems use feedback as a key strategy to cope with uncertainty and change in their environments. The information fed back from the sensorimotor loop into the control architecture can be used to change different elements of the controller at four different levels: parameters of the control model, the control model itself, the functional organization of the agent and the functional components of the agent. The complexity of such a space of potential configurations is daunting. The only viable alternative for the agent ?in practical, economical, evolutionary terms? is the reduction of the dimensionality of the configuration space. This reduction is achieved both by functionalisation —or, to be more precise, by interface minimization— and by patterning, i.e. the selection among a predefined set of organisational configurations. This last analysis let us state the central problem of how autonomy emerges from the integration of the cognitive, emotional and autonomic systems in strict functional terms: autonomy is achieved by the closure of functional dependency. In this paper we will show a general model of how the emotional biological systems operate following this theoretical analysis and how this model is also of applicability to a wide spectrum of artificial systems

    Economic Partnership Agreement Mexico - Japan : analysis of trade creation and trade diversion 1999-2013

    Get PDF
    This document seeks to make an empirical analysis of the effects of the Economic Partnership Agreement between Mexico and Japan (EPAMJ) regarding trade creation and trade diversion. Trade flows between 23 countries for the period 1999 to 2013 are employed. The methodology is an ex post model that estimates trade creation or trade diversion using the gravitational equation. The results suggest that since its entry into force the EPAMJ has created trade for both nations. No evidence of trade diversion is found as results indicate that the EPAMJ has increased Mexico and Japan\u27s trade with the other countries analyzed

    Consciousness, Meaning and the Future Phenomenology

    Get PDF
    Phenomenological states are generally considered sources of intrinsic motivation for autonomous biological agents. In this paper we will address the issue of exploiting these states for robust goal-directed systems. We will provide an analysis of consciousness in terms of a precise definition of how an agent “understands” the informational flows entering the agent. This model of consciousness and understanding is based in the analysis and evaluation of phenomenological states along potential trajectories in the phase space of the agents. This implies that a possible strategy to follow in order to build autonomous but useful systems is to embed them with the particular, ad-hoc phenomenology that captures the requirements that define the system usefulness from a requirements-strict engineering viewpoint

    Efecto de la fertilización cálcica en el desarrollo del cultivo de rosa (Rosa x hibrida) var. Freedom y vida postcosecha.

    La rosa es la principal flor de corte en México y ante el incremento de la producción en la región florícola sur del Estado de México, se requieren de técnicas de nutrición completas que sean eficientes y económicas para su manejo. Uno de los factores primordiales que influyen en la calidad de tallos florales de rosas para exportación es la nutrición mineral y en particular la nutrición cálcica la cual se encuentra muy relacionada en el crecimiento y desarrollo de las flores así como en la vida postcosecha. La presente investigación tuvo como objetivo, evaluar cinco tratamientos con diferentes dosis a base de nitrato de calcio: T1 (0), T2 (0.5), T3 (1), T4 (1.5) y T5 (2.0) kg de Ca++ aplicados en el desarrollo del tallo floral bajo invernadero, su efecto en postcosecha y vida de florero en el cultivo de rosa (Rosa x hibrida) variedad Freedom en las estaciones de invierno 2011 y verano 2012. El experimento se estableció bajo un diseño de bloques completos al azar con cinco tratamientos y cuatro repeticiones. Las variables evaluadas durante el ensayo fueron: longitud y diámetro de tallo, longitud de pedúnculo, longitud y diámetro de botón, incidencia de Botritys cinerea y vida de florero. Los resultados muestran que los tratamientos 4 (1.5 kg Ca++) y 5 (1.5 kg Ca++) fueron los que mejor efecto mostraron en el desarrollo del tallo foral. El tratamiento 4 para las variables longitud de pedúnculo, diámetro de tallo y longitud de botón fue mejor para el ciclo de invierno, sin embargo el tratamiento 5 fue mejor para el ciclo de verano con efecto en las variables diámetro de tallo y botón. En estos mismos tratamientos la incidencia de Botritys cinerea y cuello doblado fue menor de 70 y 60 % respectivamente. Los resultados confirman la importancia del calcio en la vida postcosecha en rosa y su influencia en la resistencia a enfermedades

    From transfers to capital: analyzing the Spanish demand for wealth using NTA

    Get PDF
    Inter- and intra-family transfers are a very important part of our daily economic activity. These transfers, whether familial or public, may influence our economic decisions to the same extent that financial markets do. In this paper, we seek to understand how the Spanish stock of capital will evolve if the set of intergenerational transfers observed in year 2000 are maintained in the future. With that aim in mind, we have implemented a general equilibrium overlapping generations model with realistic public and familial transfers drawn from the National Transfer Accounts project (NTA). Given that familial transfers go from parents to children, and public transfers go from children to parents, we show that the Spanish baby boom and baby bust will make the second demographic dividend temporary, and that welfare will be reduced from 2040 onwards.Spain, demographic ageing, economic demography, economic growth

    Emotions and the Engineering of Adaptiveness in Complex Systems

    Get PDF
    A major challenge in the engineering of complex and critical systems is the management of change, both in the system and in its operational environment. Due to the growing of complexity in systems, new approaches on autonomy must be able to detect critical changes and avoid their progress towards undesirable states. We are searching for methods to build systems that can tune the adaptability protocols. New mechanisms that use system-wellness requirements to reduce the influence of the outer domain and transfer the control of uncertainly to the inner one. Under the view of cognitive systems, biological emotions suggests a strategy to configure value-based systems to use semantic self-representations of the state. A method inspired by emotion theories to causally connect to the inner domain of the system and its objectives of wellness, focusing on dynamically adapting the system to avoid the progress of critical states. This method shall endow the system with a transversal mechanism to monitor its inner processes, detecting critical states and managing its adaptivity in order to maintain the wellness goals. The paper describes the current vision produced by this work-in-progress

    Nitric oxide molecular targets: reprogramming plant development upon stress

    Get PDF
    [EN] Plants are sessile organisms that need to complete their life cycle by the integration of different abiotic and biotic environmental signals, tailoring developmental cues and defense concomitantly. Commonly, stress responses are detrimental to plant growth and, despite the fact that intensive efforts have been made to understand both plant development and defense separately, most of the molecular basis of this trade-off remains elusive. To cope with such a diverse range of processes, plants have developed several strategies including the precise balance of key plant growth and stress regulators [i.e. phytohormones, reactive nitrogen species (RNS), and reactive oxygen species (ROS)]. Among RNS, nitric oxide (NO) is a ubiquitous gasotransmitter involved in redox homeostasis that regulates specific checkpoints to control the switch between development and stress, mainly by post-translational protein modifications comprising S-nitrosation of cysteine residues and metals, and nitration of tyrosine residues. In this review, we have sought to compile those known NO molecular targets able to balance the crossroads between plant development and stress, with special emphasis on the metabolism, perception, and signaling of the phytohormones abscisic acid and salicylic acid during abiotic and biotic stress responses
