Pequeño diccionario sobre la utopía: recursos para contar una historia sobre la experiencia del proyecto redesearte paz y su vocación de intervención artística y cultural en territorios en riesgo de exclusión social

Cultura, desarrollo, comunidad, territorio, arte, cohesión social, empoderamiento, desarrollo cultural comunitario, solidaridad... Todas estas palabras, todos estos términos, componen una compleja definición sobre una propuesta de transformación y futuro para contextos sociales en riesgo de exclusión. Un proyecto que es, a la vez, una red de agentes culturales, un contenedor de deseos y acciones de intervención, y un vínculo entre el arte y la cultura como motores de transformación del territorio a favor de una cultura de paz. Se trata de REDESEARTE PAZ, un proyecto que, a través de las herramientas de las prácticas artísticas contemporáneas y la cultura, genera y fortalece procesos de cohesión social. El proyecto trabaja mediante la intervención-colaboración-reflexiónacción con comunidades en peligro de marginación. El presente texto es un glosario de términos, con intención de diccionario, que trata de dibujar el amplio mapa de las acciones y los conceptos que conforman esta red; la búsqueda de una definición en la suma de todas las partes que componen la propuesta, bajo la idea de reivindicar el uso de la palabra utopía en la actualidad: recuperar esa esperanza que supone el término y a la vez compartir la experiencia de este diálogo entre el arte y la cultura propuesto por REDESEARTE PAZ a favor de la cooperación y el desarrollo

La consolidació de la propietat pagesa a Catalunya (el Baix Empordà, 1850-1940)

Aquesta tesi estudia algunes de les transformacions agràries enregistrades en un àmbit comarcal (la comarca catalana del Baix Empordà) entre mitjan segle XIX i mitjan segle XX. EI fil conductor és la distribució de la propietat del sol agrícola. Però per a la seva comprensió es considera necessari integrar moltes altres variables. EI treball també es proposa assajar alguns procediments metodològics poc habituals en l'anàlisi de la distribució de la propietat del sòl agrícola i la seva evolució en època contemporània. Com a hipòtesi central, es sosté que, al Baix Empordà i al llarg del període comprès entre 1850 i 1940, els canvis que varen produir-se en l'estructura de la propietat i, també, en I'estructura social rural, varen apuntar genèricament a favor dels grups pagesos. En particular, es sosté : ( I) Que la situació de partida (de mitjan segle XIX) ja es caracteritzava per un notable pes de la petita propietat pagesa sobre I'estructura de la propietat agrícola i sobre el conjunt del sistema agrari. (2) Que, amb posterioritat a la crisi agrària finisecular, els problemes de rendibilitat de la producció agrària i l'erosió soferta per alguns mecanismes d'extracció de renda varen tendir a allunyar els sectors rendistes que tradicionalment havien exercit la seva hegemonia -econòmica i social- en la societat rural. (3) I, finalment, que al llarg del període va produir-se un avenç de la propietat pagesa com a conseqüència del fet que una porció significativa de famílies pageses aconseguissin ampliar el seu patrimoni territorial a través de compres realitzades en el mercat de terres, alhora que un nombre significatiu de vells grans patrimonis es fraccionava i desfeia. La magnitud d'aquests canvis va ser moderada i no va pas estar exempta d'ambigüitats, però posa de relleu la capacitat de resistència i adequació de l'explotació pagesa a les condicions d'un capitalisme evolvent, malgrat els pronòstics en sentit contrari de molts teòrics. La tesi està articulada en dues parts. En la primera es duu a terme una descripció detallada de les característiques del sistema agrari baixempordanès de mitjan segle XIX amb l'objectiu final de determinar el significat econòmic de les terres posseïdes per cada patrimoni familiar (més enllà de la simple consideració de les superfícies). EI primer pas consisteix en l'anàlisi dels usos del sòl, dels conreus principals i la seva ordenació en rotacions, dels rendiments físics, de les practiques de reposició de la fertilitat i de la dotació ramadera. A continuació es descriuen les tècniques i el procés de treball agrari amb l'objectiu de formular un model d'organització del treball agrícola que permeti mesurar les exigències en treball d'aquesta activitat. Es conclou que, des de la perspectiva de l'ocupació i de la demanda de treball generades pel sistema agrari, les localitats rurals es caracteritzaven per un fort excedent de mà d'obra en relació a les demandes laborals dels conreus tant des d'una perspectiva macroeconòmica com microeconòmica. EI tercer capítol es centra en l'avaluació de les necessitats de consum i reproducció de les UFP. Les estimacions realitzades permeten proposar un model flexible, que és contrastat amb els ingressos potencialment obtenibles per cada patrimoni. S'arriba a la conclusió que només una ínfima part de la població arribava a obtenir, amb l'explotació directa del seu patrimoni, l'ingrés necessari per a la seva reproducció econòmica simple. Paral·lelament però, es posa de relleu la importància econòmica i social dels petits patrimonis pagesos. S'estima que entorn una mitjana del 45% del sòl agrícola estava posseït per aquest segment de propietaris i, en el quart capítol, s'estudien les implicacions d'aquest fet. EI retrat de la situació de partida finalitza amb l'estudi dels règims de no-propietat predominants a la comarca. En la segona part, aquesta visió estàtica deixa pas a una anàlisi dinàmica. A mitjan segle XIX, al Baix Empordà, s'estava arribant a la fi d'una llarga etapa expansiva iniciada una centúria abans. Els primers signes d'esgotament varen ser la intensa pèrdua de població rural entre 1860 i 1880, la paralització de l'expansió dels conreus i el fort desenvolupament de la industria surera, eix del nou motor econòmic comarcal. Amb posterioritat a 1860 els canvis en l'estructura distributiva de la propietat varen tendir a apuntar cap a la consolidació de la propietat pagesa. Es va produir un procés de transferència de terres des dels sectors rendistes cap a sectors pagesos que va realitzar-se a través de compravendes en el mercat de la terra més que a través d'establiments i subestabliments emfitèutics. Va tenir com a conseqüència última el retrocés dels vells patrimonis rendistes, que, en general, no varen ser substituïts per l'aparició de nous grans patrimonis, com havia pogut passar fins aleshores. Paral·lelament, un bon nombre d'unitats familiars rurals també varen anar abandonant el camp i les seves propietats, produint-se una altra línia de transferència de terres entre sectors pagesos. La depreciació sostinguda dels preus agrícoles, la caiguda de la renda agrària, la superior rendibilitat de les inversions en valors mobiliaris i la incidència d'una creixent conflictivitat agrària són els factors que es destaquen per explicar la reculada dels grans patrimonis territorials. Des de la perspectiva pagesa es proposen tres elements explicatius per interpretar el procés d'acumulació patrimonial observat en un determinat segment de població: (1) el manteniment d'estratègies de producció per a l'autoconsum (un aspecte sempre polèmic i de difícil demostració); (2) l'existència d'un flux important d'ingressos salarials i extra-agrícoles en la composició de l'ingrés familiar pagès; i (3) el canvi en les orientacions tècniques i productives de les explotacions pageses. La combinació dels tres, alhora que hauria limitat els efectes directes dels moviments dels preus agraris, hauria possibilitat l'estratègia acumulativa observada.

Insostenibilidad del pago de la deuda externa desde el punto de vista económico, social y ambiental (Tema Central)

La autora sostiene que, dadas las condiciones usualmente impuestas por los países industrializados acreedores, el pago de la deuda externa es inviable para el Ecuador. Si se consideran aspectos económicos, sociales yambientales, se puede apreciar que el actual servicio de la deuda genera una balanza de pagos insostenible, deterioro de la capacidad productiva local. aumento de la precariedad del mercado laboral, incremento de la extrema pobreza y una presión insoportable sobre los recursos naturales. Mediante un análisis de ciertos indicadores selectos, la autora establece las relaciones existentes entre el ajuste para servir a la deuda, el deterioro de las condiciones de vida, el impacto en la agricultura y los recursos naturales y la dinámica de los procesos migratorios.

¿“Primavera árabe” o reconfiguración imperial?: esperanzas y límites de la movilización social en el Medio Oriente (Coyuntura)

El presente artículo no pretende aportar respuestas definitivas a las preguntas formuladas, menos alimentar pronósticos. Busca, de manera crítica, fomentar el planteamiento de nuevas interrogaciones que contribuyan a un acercamiento científico, es decir anti-mediático, respecto de fenómenos presentes en la actualidad del Medio Oriente. ¿La fuerza espontánea de la movilización social logrará superar la inercia de las dinámicas imperiales que ritmaron la historia política del Medio Oriente? ¿Podrá romper las cadenas del círculo vicioso de la maldición de la abundancia? Estas preguntas quedan enteras. Sin embargo, una posible respuesta no se verá en la mal llamada “primavera árabe” un fin en sí, sino el comienzo de un despertar colectivo. El fortalecimiento de las capacidades organizativas y movilizadoras de las masas populares del Medio Oriente constituye, sin duda, un primer paso fundamental para el arranque de un proceso histórico nuevo, dominado por los afanes de emancipación.

Understanding the processes governing climate variability and change, climate predictability and the probability of extreme events

The purpose of Research Theme 4 (RT4) was to advance understanding of the basic science issues at the heart of the ENSEMBLES project, focusing on the key processes that govern climate variability and change, and that determine the predictability of climate. Particular attention was given to understanding linear and non-linear feedbacks that may lead to climate surprises,and to understanding the factors that govern the probability of extreme events. Improved understanding of these issues will contribute significantly to the quantification and reduction of uncertainty in seasonal to decadal predictions and projections of climate change. RT4 exploited the ENSEMBLES integrations (stream 1) performed in RT2A as well as undertaking its own experimentation to explore key processes within the climate system. It was working at the cutting edge of problems related to climate feedbacks, the interaction between climate variability and climate change � especially how climate change pertains to extreme events, and the predictability of the climate system on a range of time-scales. The statisticalmethodologies developed for extreme event analysis are new and state-of-the-art. The RT4-coordinated experiments, which have been conducted with six different atmospheric GCMs forced by common timeinvariant sea surface temperature (SST) and sea-ice fields (removing some sources of inter-model variability), are designed to help to understand model uncertainty (rather than scenario or initial condition uncertainty) in predictions of the response to greenhouse-gas-induced warming. RT4 links strongly with RT5 on the evaluation of the ENSEMBLES prediction system and feeds back its results to RT1 to guide improvements in the Earth system models and, through its research on predictability, to steer the development of methods for initialising the ensembles

Modelling climate change: the role of unresolved processes

Our understanding of the climate system has been revolutionized recently, by the development of sophisticated computer models. The predictions of such models are used to formulate international protocols, intended to mitigate the severity of global warming and its impacts. Yet, these models are not perfect representations of reality, because they remove from explicit consideration many physical processes which are known to be key aspects of the climate system, but which are too small or fast to be modelled. The purpose of this paper is to give a personal perspective of the current state of knowledge regarding the problem of unresolved scales in climate models. A recent novel solution to the problem is discussed, in which it is proposed, somewhat counter-intuitively, that the performance of models may be improved by adding random noise to represent the unresolved processes.

Embodied social capital and geographic perspectives: performing the habitus

This paper reopens debates of geographic theorizations and conceptualizations of social capital. I argue that human geographers have tended to underplay the analytic value of social capital, by equating the concept with dominant policy interpretations. It is contended that geographers could more explicitly contribute to pervasive critical social science accounts. With this in mind, an embodied perspective of social capital is constructed. This synthesizes Bourdieu's capitals and performative theorizations of identity, to progress the concept of social capital in four key ways. First, this theorization more fully reconnects embodied differences to broader socioeconomic processes. Second, an exploration of how embodied social differences can emerge directly from the political-economy and/or via broader operations of power is facilitated. Third, a path is charted through the endurance of embodied inequalities and the potential for social transformation. Finally, embodied social capital can advance social science conceptualizations of the spatiality of social capital, by illuminating the importance of broader sociospatial contexts and relations to the embodiment of social capital within individuals.

Quantifying uncertainty in the simulation of crop-climate processes

The impacts of climate change on crop productivity are often assessed using simulations from a numerical climate model as an input to a crop simulation model. The precision of these predictions reflects the uncertainty in both models. We examined how uncertainty in a climate (HadAM3) and crop General Large-Area Model (GLAM) for annual crops model affects the mean and standard deviation of crop yield simulations in present and doubled carbon dioxide (CO2) climates by perturbation of parameters in each model. The climate sensitivity parameter (λ, the equilibrium response of global mean surface temperature to doubled CO2) was used to define the control climate. Observed 1966–1989 mean yields of groundnut (Arachis hypogaea L.) in India were simulated well by the crop model using the control climate and climates with values of λ near the control value. The simulations were used to measure the contribution to uncertainty of key crop and climate model parameters. The standard deviation of yield was more affected by perturbation of climate parameters than crop model parameters in both the present-day and doubled CO2 climates. Climate uncertainty was higher in the doubled CO2 climate than in the present-day climate. Crop transpiration efficiency was key to crop model uncertainty in both present-day and doubled CO2 climates. The response of crop development to mean temperature contributed little uncertainty in the present-day simulations but was among the largest contributors under doubled CO2. The ensemble methods used here to quantify physical and biological uncertainty offer a method to improve model estimates of the impacts of climate change.

Prefrontal social cognition network dysfunction underlying face encoding and social anxiety in fragile X syndrome

Individuals with fragile X syndrome (FXS) commonly display characteristics of social anxiety, including gaze aversion, increased time to initiate social interaction, and difficulty forming meaningful peer relationships. While neural correlates of face processing, an important component of social interaction, are altered in FXS, studies have not examined whether social anxiety in this population is related to higher cognitive processes, such as memory. This study aimed to determine whether the neural circuitry involved in face encoding was disrupted in individuals with FXS, and whether brain activity during face encoding was related to levels of social anxiety. A group of 11 individuals with FXS (5 M) and 11 age-and gender-matched control participants underwent fMRI scanning while performing a face encoding task with onlineeye-tracking. Results indicate that compared to the control group, individuals with FXS exhibited decreased activation of prefrontal regions associated with complex social cognition, including the medial and superior frontal cortex, during successful face encoding. Further, the FXS and control groups showed significantly different relationships between measures of social anxiety (including gaze-fixation) and brain activity during face encoding. These data indicate that social anxiety in FXS may be related to the inability to successfully recruit higher level social cognition regions during the initial phases of memory formation.

Predicting fault inflow in iterative software development processes: an industrial evaluation

This paper addresses the need for accurate predictions on the fault inflow, i.e. the number of faults found in the consecutive project weeks, in highly iterative processes. In such processes, in contrast to waterfall-like processes, fault repair and development of new features run almost in parallel. Given accurate predictions on fault inflow, managers could dynamically re-allocate resources between these different tasks in a more adequate way. Furthermore, managers could react with process improvements when the expected fault inflow is higher than desired. This study suggests software reliability growth models (SRGMs) for predicting fault inflow. Originally developed for traditional processes, the performance of these models in highly iterative processes is investigated. Additionally, a simple linear model is developed and compared to the SRGMs. The paper provides results from applying these models on fault data from three different industrial projects. One of the key findings of this study is that some SRGMs are applicable for predicting fault inflow in highly iterative processes. Moreover, the results show that the simple linear model represents a valid alternative to the SRGMs, as it provides reasonably accurate predictions and performs better in many cases.

the implication of social cognition for experimental economics From the issue entitled "Special issue on Experimental economics and the social embedding of economic behavior and cognition"

Can human social cognitive processes and social motives be grasped by the methods of experimental economics? Experimental studies of strategic cognition and social preferences contribute to our understanding of the social aspects of economic decisions making. Yet, papers in this issue argue that the social aspects of decision-making introduce several difficulties for interpreting the results of economic experiments. In particular, the laboratory is itself a social context, and in many respects a rather distinctive one, which raises questions of external validity.

Specialization of right temporo-parietal junction for mentalizing and its relation to social impairments in autism

Over the last 25years, "mindblindness" (deficits in representing mental states) has been one of the primary explanations behind the hallmark social-communication difficulties in autism spectrum conditions (ASC). However, highlighting neural systems responsible for mindblindness and their relation to variation in social impairments has remained elusive. In this study we show that one of the neural systems responsible for mindblindness in ASC and its relation to social impairments is the right temporo-parietal junction (RTPJ). Twenty-nine adult males with ASC and 33 age and IQ-matched Controls were scanned with fMRI while making reflective mentalizing or physical judgments about themselves or another person. Regions of interest within mentalizing circuitry were examined for between-group differences in activation during mentalizing about self and other and correlations with social symptom severity. RTPJ was the only mentalizing region that responded atypically in ASC. In Controls, RTPJ was selectively more responsive to mentalizing than physical judgments. This selectivity for mentalizing was not apparent in ASC and generalized across both self and other. Selectivity of RTPJ for mentalizing was also associated with the degree of reciprocal social impairment in ASC. These results lend support to the idea that RTPJ is one important neural system behind mindblindness in ASC. Understanding the contribution of RTPJ in conjunction with other neural systems responsible for other component processes involved in social cognition will be illuminating in fully explaining the hallmark social-communication difficulties of autism.

Developing children and young people’s participation in strategic processes: the experience of the Children’s Fund Initiative

The extent of children’s and young people’s participation activities has increased considerably among statutory, voluntary and community sector organisations across the UK in recent years. The Children’s Fund, a major government initiative launched in 2000, represents a systematic drive towards promoting children and young people’s participation in planning, implementing and evaluating preventative services within all 149 local authority areas in England. Based on research carried out by the National Evaluation of the Children’s Fund, this paper explores the experience of Children’s Fund partnerships of engaging children and young people in strategic processes.

A micro-level simulation for the prediction of intention and behaviour

In this contribution we aim at anchoring Agent-Based Modeling (ABM) simulations in actual models of human psychology. More specifically, we apply unidirectional ABM to social psychological models using low level agents (i.e., intra-individual) to examine whether they generate better predictions, in comparison to standard statistical approaches, concerning the intentions of performing a behavior and the behavior. Moreover, this contribution tests to what extent the predictive validity of models of attitude such as the Theory of Planned Behavior (TPB) or Model of Goal-directed Behavior (MGB) depends on the assumption that peoples’ decisions and actions are purely rational. Simulations were therefore run by considering different deviations from rationality of the agents with a trembling hand method. Two data sets concerning respectively the consumption of soft drinks and physical activity were used. Three key findings emerged from the simulations. First, compared to standard statistical approach the agent-based simulation generally improves the prediction of behavior from intention. Second, the improvement in prediction is inversely proportional to the complexity of the underlying theoretical model. Finally, the introduction of varying degrees of deviation from rationality in agents’ behavior can lead to an improvement in the goodness of fit of the simulations. By demonstrating the potential of ABM as a complementary perspective to evaluating social psychological models, this contribution underlines the necessity of better defining agents in terms of psychological processes before examining higher levels such as the interactions between individuals.

Exploring social barriers to adaptation: insights from Western Nepal

As the challenges and opportunities posed by climate change become increasingly apparent, the need for facilitating successful adaptation and enhancing adaptive capacity within the context of sustainable development is clear. With adaptation high on the agenda, the notion of limits and barriers to adaptation has recently received much attention within both academic and policymaking spheres. While emerging literature has been quick to depict limits and barriers in terms of natural, financial, or technologic processes, there is a clear shortfall in acknowledging social barriers to adaptation. It is against such a backdrop that this paper sets out to expose and explore some of the underlying features of social barriers to adaptation, drawing on insights from two case studies in the Western Nepal. This paper exposes the significant role of cognitive, normative and institutional factors in both influencing and prescribing adaptation. It explores how restrictive social environments can limit adaptation actions and influence adaptive capacity at the local level, particularly for the marginalised and socially excluded. The findings suggest a need for greater recognition of the diversity and complexity of social barriers, strategic planning and incorporation at national and local levels, as well as an emphasis on tackling the underlying drivers of vulnerability and social exclusion.
