Language, Thought, Relativism, Nationalism: An Interdisciplinary Study

Ms. Neumer and her team began their project with a critical analysis of the various theories of the relationship between language and thought. Their aim was to develop a theoretical position concerning the issue of universalism versus relativism. This issue is closely bound up with one of the main questions of the history of East and Central Europe, namely, the question of the nation, and the possibility of mutual understanding between national cultures. The team attempted to avoid falling into an all-too-common trap, that of allowing a political perspective to obscure the central theoretical issues. In a project whose outcome totalled over 1000 pages of manuscript in German, English and Hungarian, they touched on cognitive psychological, linguistic, semiotic, socio-semiotic, and other such themes. Their experience has convinced them of the fruitful heuristic possibilities of the interaction of scientific and philosophical approaches in this area of research. A preliminary analysis of the history of philosophy and inquiries into conceptual fields revealed that, in order to reach strong relativist conclusions concerning the unity of thought and language, it is required to take as a point of departure the widest possible sense of these concepts. But in fact, such an option ends up refuting itself: pursuing the premises to their final conclusion one arrives at the restriction of relativism. The team outlined a theory of the understanding of the Other which, borrowing from analytical as well as continental-hermeneutic trends, does not underestimate, on the one hand, the difficulties of understanding between various forms of life, cultures, and languages, but, on the other hand, can provide an alternative solution to the theory of incommensurabiltiy. Within the boundary of this problematic the team studied the problems of translatability, the acquisition of the mother and foreign languages, and natural or cultural determinacy of kind terms. The team regards its most original contribution to be the association of the problem of relativism-universalism and the language-thought relation with contemporary investigations into the question of orality, literacy, and secondary orality. Their conclusion was that, although certain connections can be revealed both between forms of communication and the thesis of the unity of language and thought, and between periods in the history of communication and the predominance of relativistic or universalistic tendencies, forms of communication do not unequivocally determine the answers to these questions.

Enhancing Food Sovereignty and Food Security through the Revitalization of Indigenous Knowledge: Experiences from the Bolivian Andes

Endogenous development is defined as development that values primarily locally available resources and the way people organized themselves for that purpose. It is a dynamic and evolving concept that also embraces innovations and complementation from other than endogenous sources of knowledge; however, only as far as they are based on mutual respect and the recognition of cultural and socioeconomic self-determination of each of the parties involved. Experiences that have been systematized in the context of the BioAndes Program are demonstrating that enhancing food security and food sovereignty on the basis of endogenous development can be best achieved by applying a ‘biocultural’ perspective: This means to promote and support actions that are simultaneously valuing biological (fauna, flora, soils, or agrobiodiversity) and sociocultural resources (forms of social organization, local knowledge and skills, norms, and the related worldviews). In Bolivia, that is one of the Latin-American countries with the highest levels of poverty (79% of the rural population) and undernourishment (22% of the total population), the Program BioAndes promotes food sovereignty and food security by revitalizing the knowledge of Andean indigenous people and strengthening their livelihood strategies. This starts by recognizing that Andean people have developed complex strategies to constantly adapt to highly diverse and changing socioenvironmental conditions. These strategies are characterized by organizing the communities, land use and livelihoods along a vertical gradient of the available eco-climatic zones; the resulting agricultural systems are evolving around the own sociocultural values of reciprocity and mutual cooperation, giving thus access to an extensive variety of food, fiber and energy sources. As the influences of markets, competition or individualization are increasingly affecting the life in the communities, people became aware of the need to find a new balance between endogenous and exogenous forms of knowledge. In this context, BioAndes starts by recognizing the wealth and potentials of local practices and aims to integrate its actions into the ongoing endogenous processes of innovation and adaptation. In order to avoid external impositions and biases, the program intervenes on the basis of a dialogue between exogenous, mainly scientific, and indigenous forms of knowledge. The paper presents an analysis of the strengths and weaknesses of enhancing endogenous development through a dialogue between scientific and indigenous knowledge by specifically focusing on its effects on food sovereignty and food security in three ‘biocultural’ rural areas of the Bolivian highlands. The paper shows how the dialogue between different forms of knowledge evolved alongside the following project activities: 1) recuperation and renovation of local seeds and crop varieties (potato – Solanum spp., quinoa – Chenopodium quinoa, cañahua – Chenopodium pallidicaule); 2) support for the elaboration of community-based norms and regulations for governing access and distribution of non-timber forest products, such as medicinal, fodder, and construction plants; 3) revitalization of ethnoveterinary knowledge for sheep and llama breeding; 4) improvement of local knowledge about the transformation of food products (sheep-cheese, lacayote – Cucurbita sp. - jam, dried llama meat, fours of cañahua and other Andean crops). The implementation of these activities fostered the community-based livelihoods of indigenous people by complementing them with carefully and jointly designed innovations based on internal and external sources of knowledge and resources. Through this process, the epistemological and ontological basis that underlies local practices was made visible. On this basis, local and external actors started to jointly define a renewed concept of food security and food sovereignty that, while oriented in the notions of well being according to a collectively re-crafted world view, was incorporating external contributions as well. Enabling and hindering factors, actors and conditions of these processes are discussed in the paper.

Acceptance as a coping reaction: Adaptive or not?

Acceptance as a coping reaction to unchangeable negative events has been discussed controversially. While some studies suggest it is adaptive, others report negative effects on mental health. We propose a distinction between two forms of acceptance reactions: active acceptance, which is associated with positive psychological outcomes, and resigning acceptance, which is associated with negative psychological outcomes. In this study, 534 individuals were surveyed with respect to several hypothetical situations. We tested the proposed acceptance model by confirmatory factor analysis, and examined the convergent and discriminant validity using personality and coping measures (Trier Personality Questionnaire, Bernese Bitterness Questionnaire, COPE). The results support the distinction between the two forms of acceptance reactions, and, in particular, that active acceptance is an adaptive reaction to unchangeable situations.

The Circle: Die neue Kolonisierung des inneren Menschen

Mit Hilfe des zeitgenössischen Romans 'The Circle' von Dave Eggers werden Entgrenzungs- und Verdichtungstendenzen moderner subjektivierter Arbeit illustriert, die einen Zusammenhang mit Burnout- und Erschöpfungsdepressionsdiagnosen plausibilisieren. Angesichts der Uneindeutigkeit der empirischen Evidenz wird vorgeschlagen, die Problematik der modernen Gestalt der Erwerbsarbeit – vor allem für diejenigen am unteren Ende der jeweiligen Hierarchien – nicht nur anhand ihrer Krankheitsträchtigkeit, sondern mit Hilfe des Konzepts der Lebensformen und ihrer normativen Aufladung zu kritisieren: Massiv entgrenzte und verdichtete Arbeit erscheint dann als Bruch des 'Arbeitsversprechens', das sich mit Entstehung der Arbeitsgesellschaft im 19. Jh. herausgebildet hat.

Biometry, isotopic composition and diet of Arctic charr (Salvelinus alpinus) from Lake Aigneau, Northern Quebec

Two modal size groups of sexually mature Arctic charr (Salvelinus alpinus) differing in shape and found at different depths in Lake Aigneau in the Canadian sub-Arctic are described and tested for genetic and ecological differentiation. Forms consisted of a small littoral resident, mean size 21.7 cm, and a large profundal resident, mean size 53.9 cm. Mitochondrial DNA analysis indicated that seven of eight haplotypes were diagnostic for either the littoral or profundal fish, with 66.6% of the variation being found within form groupings. Pairwise tests of microsatellite data indicated significant differences in nine of 12 loci and a significant difference between the forms across all tested loci. Molecular variation was partitioned to 84.1% within and 15.9% between forms and suggestive of either restricted interbreeding over time or different allopatric origins. Stable isotope signatures were also significantly different, with the profundal fish having higher d13C and d15N values than the littoral fish. Overlap and separation, respectively, in the range of form d13C and d15N signatures indicated that carbon was obtained from similar sources, but that forms fed at different trophic levels. Littoral fish relied on aquatic insects, predominantly chironomids. Profundal fish were largely piscivorous, including cannibalism. Predominantly empty stomachs and low per cent nitrogen muscle-tissue composition among profundal fish further indicated that the feeding activity was limited to the winter when ice-cover increases the density of available prey at depth. Results provide evidence of significant differences between the modal groups, with origins in both genetics and ecology.

Gobernar la complejidad urbana desde la sostenibilidad. Evaluación del gobierno de la gestión visible utilizando indicadores de gobernanza (Venezuela)

Se evalúa con indicadores de gobernanza urbana la sostenibilidad de las formas de hacer ciudad hibrida compleja del gobierno de la gestión visible (GGV). Argumenta que el GGV hace ciudad para legitimarse por desempeño y fortalecer la gobernanza local, en un contexto de mutaciones múltiples y radicales que tienden a diluir y centralizar el poder local y fractalizar la ciudad, profundizando la segregación sociopolítica-territorial y la ingobernabilidad genética de la ciudad hibrida, poniendo en riesgo el Estado federal descentralizado, el derecho a la ciudad, al gobierno local y la gobernanza urbana y multinivel (hipótesis). La estrategia de evaluación de gobernanza innovadora (EEG+i) diseñada para evaluar la relación entre las formas de hacer ciudad hibrida (variables espaciales) y gobernanza (variable a-espacial) es transversal, multidimensional y se construye desde la complejidad, el análisis de escenarios, formulación de constructos, modelos e indicadores de gobernanza, entretejiendo tres campos de conocimiento, gobierno, ciudad y sostenibilidad, en cuatro fases. La Fase 1, contextualiza la gobernanza en la dramática del siglo XXI. La Fase 2, desarrolla la fundamentación teórico-práctica, nuevos conceptos y un abordaje analítico propio ‘genética territorial’, para analizar y comprehender la complejidad de la ciudad hibrida de países en desarrollo, tejiendo ontogenética territorial y el carácter autopoiético del gen informal. En la Fase 3, se caracterizan las formas de hacer ciudad desde la genética del territorio, se formulan modelos e indicadores de gobernanza con los que se evalúan, aplicando un delphi y cuestionarios, los genes tipológicos-formas de hacer ciudad y validan las conclusiones. En la Fase 4, se correlacionan los resultados de los instrumentos aplicados con la praxis urbana del GGV, durante cuatro periodos de gobierno (1996-2010). Concluyendo que, la estrategia de evaluación comprobó las hipótesis y demostró la correlación transversal y multinivel existente entre, las mutaciones en curso que contradicen el modelo de gobernanza constitucional, el paisaje de gobernanza latinoamericano y venezolano, la praxis de los regímenes híbridos ricos en recursos naturales, las perspectivas de desarrollo globales y se expresa sociopolíticamente en déficit de gobernanza, Estado de derecho y cohesión-capital social y, espaciolocalmente, en la ciudad hibrida dispersa y diluida (compleja) y en el gobierno del poder diluido centralizado. La confrontación de flujos de poder centrípetos y centrífugos en la ciudad profundiza la fragmentación socioespacial y política y el deterioro de la calidad de vida, incrementando las protestas ciudadanas e ingobernabilidad que obstaculiza la superación de la pobreza y gobernanza urbana y multinivel. La evaluación de la praxis urbana del GGV evidenció que la correlación entre gobernanza, la producción de genes formales y la ciudad por iniciativa privada tiende a ser positiva y entre gobernanza, genes y producción de ciudad informal negativa, por el carácter autopoiético-autogobernable del gen informal y de los nuevos gobiernos sublocales que dificulta gobernar en gobernanza. La praxis del GGV es contraria al modelo de gobernanza formulado y la disolución centralizada del gobierno local y de la ciudad hibrida-dispersa es socio-espacial y políticamente insostenible. Se proponen estrategias y tácticas de gobernanza multinivel para recuperar la cohesión social y de planificación de la gestión innovadora (EG [PG] +i) para orquestar, desde el Consejo Local de Gobernanza (CLG) y con la participación de los espacios y gobiernos sublocales, un proyecto de ciudad compartido y sostenible. ABSTRACT The sustainability of the forms of making the hybrid-complex city by the visible management government (VMG) is evaluated using urban governance indicators. Argues that the VMG builds city to legitimate itself by performance and to strengthen local governance in a context of multiple and radical mutations that tend to dilute and centralize local power and fractalize the city, deepening the socio-spatial and political segregation, the genetic ingovernability of the hybrid city and placing the decentralized federal State, the right to city, local government and urban governance at risk (hypothesis). The innovative governance evaluation strategy (GES+i) designed to assess the relationship between the forms of making the hybrid city (spatial variables) and governance (a-spatial variable) is transversal, multidimensional; is constructed from complexity, scenario analysis, the formulation of concepts, models and governance indicators, weaving three fields of knowledge, government, city and sustainability in four phases. Phase 1, contextualizes governance in the dramatic of the twenty-first century. Phase 2, develops the theoretical and practical foundations, new concepts and a proper analytical approach to comprehend the complexity of the hybrid city from developing countries, weaving territorial ontogenetic with the autopiethic character of the informal city gen. In Phase 3, the ways of making city are characterized from the genetics of territory; governance indicators and models are formulated to evaluate, using delphi and questionnaires, the ways of making city and validate the conclusions. In Phase 4, the results of the instruments applied are correlated with the urban praxis of the VMG during the four periods of government analyzed (1996-2010). Concluding that, the evaluation strategy proved the hypothesis and showed the transversal and multilevel correlation between, mutations that contradict the constitutional governance model, the governance landscape of Latinamerica and the country, the praxis of the hybrid regimes rich in natural resources, the perspectives of the glocal economy and expresses socio-politically the governance and rule of law and social capital-cohesion deficit and spatial-temporarily the hybrid disperse and diluted city (complex) and the diluted-centralized local government. The confrontation of flows of power centripetal and centrifugal in the city deepens the socio-spatial and political fragmentation and deterioration of the quality of life, increasing citizens' protests and ingovernability which hinders poverty eradication and, multilevel and urban governance. The evaluation of the VMG urban praxis showed the correlation between governance, the production of formal genes and city by private initiative tended to be positive and, between informal genes-city production and governance negative, due to its autopiethic-self governable character that hinders governance. The urban praxis of the VMG contradicts the formulated governance model and thecentralized dissolution of the local government and hybrid city are socio-spatial and politically unsustainable. Multiscale governance strategies are proposed to recreate social cohesion and a management planning innovative method (EG [PG] + i) to orchestrate, from the Local Governance Council (LGC) and with the participation of sublocal governments and spaces, a shared and sustainable city project.

Riparian woodland encroachment following flow regulation: a comparative study of Boreal and Mediterranean streams

Water development accompanying mankind development has turned rivers into endangered ecosystems. Improving the understanding of ecological responses to river management actions is a key issue for assuring sustainable water management. However, few studies have been published where ecological metrics have been quantified in response to various degrees of flow alteration. In this work, changes in natural distribution of trees and shrubs within the riparian corridor (as indicator of the ecological status of the fluvial ecosystem) were quantified at multiple sites along a flow alteration gradient (as indicator of impact) along two regulated river reaches, one Boreal and the other Mediterranean, each downstream of a dam. Based on the obtained relationships we evaluated differences in response trends related to local physico-climatic factors of the two biomes and regarding to differing life-forms. Woody vegetation establishment patterns represented objective indicators of ecological responses to flow alteration. We found different responses between life-forms. Both trees and shrubs migrated downwards to the channel after dam closure, but shrubs were most impacted under higher degrees of flow alteration in terms of lateral movement. In addition, our results show clear longitudinal recovery trends of natural patterns of tree and shrub distribution corresponding to a decrease in intensity of hydrologic alteration in the Boreal river. However, vegetation encroachment persisted along the entire Mediterranean study reach. This may result from a relatively low gradient of decrease of hydrologic alteration with distance from the dam, coupled with other overlapping pressures and the mediating effect of physico-climatic characteristics on vegetation responses.

Proyectando entre ruinas : lógicas de intervención continua en la arquitectura contemporánea

Los cambios percibidos hacia finales del siglo XX y a principios del nuevo milenio, nos ha mostrado que la crisis cultural de la que somos participes refleja también una crisis de los modelos universales. Nuestra situación contemporánea, parece indicar que ya no es posible formular un sistema estético para atribuirle una vigencia universal e intemporal más allá de su estricta eficacia puntual. La referencia organizada, delimitada, invariable y específica que ofrecía cualquier emplazamiento, en tanto preexistencia, reflejaba una jerarquía del sistema formal basado en lo extensivo: la medida, las normas, el movimiento, el tiempo, la modulación, los códigos y las reglas. Sin embargo, actualmente, algunos aspectos que permanecían latentes sobre lo construido, emergen bajo connotaciones intensivas, transgrediendo la simple manifestación visual y expresiva, para centrase en las propiedades del comportamiento de la materia y la energía como determinantes de un proceso de adaptación en el entorno. A lo largo del todo el siglo XX, el desarrollo de la relación del proyecto sobre lo construido ha sido abordado, casi en exclusiva, entre acciones de preservación o intervención. Ambas perspectivas, manifestaban esfuerzos por articular un pensamiento que diera una consistencia teórica, como soporte para la producción de la acción aditiva. No obstante, en las últimas décadas de finales de siglo, la teoría arquitectónica terminó por incluir pensamientos de otros campos que parecen contaminar la visión sesgada que nos refería lo construido. Todo este entramado conceptual previo, aglomeraba valiosos intentos por dar contenido a una teoría que pudiese ser entendida desde una sola posición argumental. Es así, que en 1979 Ignasi Solá-Morales integró todas las imprecisiones que referían una actuación sobre una arquitectura existente, bajo el termino de “intervención”, el cual fue argumentado en dos sentidos: El primero referido a cualquier tipo de actuación que se puede hacer en un edificio, desde la defensa, preservación, conservación, reutilización, y demás acciones. Se trata de un ámbito donde permanece latente el sentido de intensidad, como factor común de entendimiento de una misma acción. En segundo lugar, más restringido, la idea de intervención se erige como el acto crítico a las ideas anteriores. Ambos representan en definitiva, formas de interpretación de un nuevo discurso. “Una intervención, es tanto como intentar que el edificio vuelva a decir algo o lo diga en una determinada dirección”. A mediados de 1985, motivado por la corriente de revisión historiográfica y la preocupación del deterioro de los centros históricos que recorría toda Europa, Solá-Morales se propone reflexionar sobre “la relación” entre una intervención de nueva arquitectura y la arquitectura previamente existente. Relación condicionada estrictamente bajo consideraciones lingüísticas, a su entender, en sintonía con toda la producción arquitectónica de todo el siglo XX. Del Contraste a la Analogía, resumirá las transformaciones en la concepción discursiva de la intervención arquitectónica, como un fenómeno cambiante en función de los valores culturales, pero a su vez, mostrando una clara tendencia dialógica entres dos categorías formales: El Contraste, enfatizando las posibilidades de la novedad y la diferencia; y por otro lado la emergente Analogía, como una nueva sensibilidad de interpretación del edificio antiguo, donde la semejanza y la diversidad se manifiestan simultáneamente. El aporte reflexivo de los escritos de Solá-Morales podría ser definitivo, si en las últimas décadas antes del fin de siglo, no se hubiesen percibido ciertos cambios sobre la continuidad de la expresión lingüística que fomentaba la arquitectura, hacia una especie de hipertrofia figurativa. Entre muchos argumentos: La disolución de la consistencia compositiva y el estilo unitario, la incorporación volumétrica del proyecto como dispositivo reactivo, y el cambio de visión desde lo retrospectivo hacia lo prospectivo que sugiere la nueva conservación. En este contexto de desintegración, el proyecto, en tanto incorporación o añadido sobre un edificio construido, deja de ser considerado como un apéndice volumétrico subordinado por la reglas compositivas y formales de lo antiguo, para ser considerado como un organismo de orden reactivo, que produce en el soporte existente una alteración en su conformación estructural y sistémica. La extensión, antes espacial, se considera ahora una extensión sensorial y morfológica con la implementación de la tecnología y la hiper-información, pero a su vez, marcados por una fuerte tendencia de optimización energética en su rol operativo, ante el surgimiento del factor ecológico en la producción contemporánea. En una sociedad, como la nuestra, que se está modernizando intensamente, es difícil compartir una adecuada sintonía con las formas del pasado. Desde 1790, fecha de la primera convención francesa para la conservación de monumentos, la escala de lo que se pretende preservar es cada vez más ambiciosa, tanto es así, que al día de hoy el repertorio de lo que se conserva incluye prácticamente todas las tipologías del entorno construido. Para Koolhaas, el intervalo entre el objeto y el momento en el cual se decide su conservación se ha reducido, desde dos milenios en 1882 a unas décadas hoy en día. En breve este lapso desaparecerá, demostrando un cambio radical desde lo retrospectivo hacia lo prospectivo, es decir, que dentro de poco habrá que decidir que es lo que se conserva antes de construir. Solá-Morales, en su momento, distinguió la relación entre lo nuevo y lo antiguo, entre el contraste y la analogía. Hoy casi tres décadas después, el objetivo consiste en evaluar si el modelo de intervención arquitectónica sobre lo construido se ha mantenido desde entonces o si han aparecido nuevas formas de posicionamiento del proyecto sobre lo construido. Nuestro trabajo pretende demostrar el cambio de enfoque proyectual con la preexistencia y que éste tiene estrecha relación con la incorporación de nuevos conceptos, técnicas, herramientas y necesidades que imprimen el contexto cultural, producido por el cambio de siglo. Esta suposición nos orienta a establecer un paralelismo arquitectónico entre los modos de relación en que se manifiesta lo nuevo, entre una posición comúnmente asumida (Tópica), genérica y ortodoxa, fundamentada en lo visual y expresivo de las últimas décadas del siglo XX, y una realidad emergente (Heterotópica), extraordinaria y heterodoxa que estimula lo inmaterial y que parece emerger con creciente intensidad en el siglo XXI. Si a lo largo de todo el siglo XX, el proyecto de intervención arquitectónico, se debatía entre la continuidad y discontinuidad de las categorías formales marcadas por la expresión del edificio preexistente, la nueva intervención contemporánea, como dispositivo reactivo en el paisaje y en el territorio, demanda una absoluta continuidad, ya no visual, expresiva, ni funcional, sino una continuidad fisiológica de adaptación y cambio con la propia dinámica del territorio, bajo nuevas reglas de juego y desplegando planes y estrategias operativas (proyectivas) desde su propia lógica y contingencia. El objeto de esta investigación es determinar los nuevos modos de continuidad y las posibles lógicas de producción que se manifiestan dentro de la Intervención Arquitectónica, intentando superar lo aparente de su relación física y visual, como resultado de la incorporación del factor operativo desplegado por el nuevo dispositivo contemporáneo. Creemos que es acertado mantener la senda connotativa que marca la denominación intervención arquitectónica, por aglutinar conceptos y acercamientos teóricos previos que han ido evolucionando en el tiempo. Si bien el término adolece de mayor alcance operativo desde su formulación, una cualidad que infieren nuestras lógicas contemporáneas, podría ser la reformulación y consolidación de un concepto de intervención más idóneo con nuestros tiempos, anteponiendo un procedimiento lógico desde su propia necesidad y contingencia. Finalmente, nuestro planteamiento inicial aspira a constituir un nueva forma de reflexión que nos permita comprender las complejas implicaciones que infiere la nueva arquitectura sobre la preexistencia, motivada por las incorporación de factores externos al simple juicio formal y expresivo preponderante a finales del siglo XX. Del mismo modo, nuestro camino propuesto, como alternativa, permite proyectar posibles sendas de prospección, al considerar lo preexistente como un ámbito que abarca la totalidad del territorio con dinámicas emergentes de cambio, y con ellas, sus lógicas de intervención.Abstract The perceived changes towards the end of the XXth century and at the beginning of the new milennium have shown us that the cultural crisis in which we participate also reflects a crisis of the universal models. The difference between our contemporary situation and the typical situations of modern orthodoxy and post-modernistic fragmentation, seems to indicate that it is no longer possible to formulate a valid esthetic system, to assign a universal and eternal validity to it beyond its strictly punctual effectiveness; which is even subject to questioning because of the continuous transformations that take place in time and in the sensibility of the subject itself every time it takes over the place. The organised reference that any location offered, limited, invariable and specific, while pre-existing, reflected a hierarchy of the formal system based on the applicable: measure, standards, movement, time, modulation, codes and rules. Authors like Marshall Mc Luhan, Paul Virilio, or Marc Augé anticipated a reality where the conventional system already did not seem to respond to the new architectural requests in which information, speed, disappearance and the virtual had blurred the traditional limits of place; pre-existence did no longer possess a specific delimitation and, on the contrary, they expect to reach a global scale. Currently, some aspects that stayed latent relating to the constructed, surface from intensive connotations, transgressing the simple visual and expressive manifestation in order to focus on the traits of the behaviour of material and energy as determinants of a process of adaptation to the surroundings. Throughout the entire Century, the development of the relation of the project relating to the constructed has been addressed, almost exclusively, in preservational or interventianal actions. Both perspectives showed efforts in order to express a thought that would give a theoretical consistency as a base for the production of the additive action. Nevertheless, the last decades of the Century, architectural theory ended up including thoughts from other fields that seem to contaminate the biased vision 15 which the constructed related us. Ecology, planning, philosophy, global economy, etc, suggest new approaches to the construction of the contemporary city; but this time with a determined idea of change and continuous transformation, that enriches the panorama of thought and architectural practice, at the same time, according to some, it puts disciplinary specification at risk, given that there is no architecture without destruction, the constructed organism requires mutation in order to adjust to the change of shape. All of this previous conceptual framework gathered valuable intents to give importance to a theory that could be understood solely from an argumental position. Thusly, in 1979 Ignasi Solá-Morales integrated all of the imprecisions that referred to an action in existing architecture under the term of “Intervention”, which was explained in two ways: The first referring to any type of intervention that can be carried out in a building, regarding protection, conservation, reuse, etc. It is about a scope where the meaning of intensity stays latent as a common factor of the understanding of a single action. Secondly, more limitedly, the idea of intervention is established as the critical act to the other previous ideas such as restauration, conservation, reuse, etc. Both ultimately represent ways of interpretation of a new speech. “An intervention, is as much as trying to make the building say something again or that it be said in a certain direction”. Mid 1985, motivated by the current of historiographical revision and the concerns regarding the deterioration of historical centres that traversed Europe, Solá-Morales decides to reflect on “the relationship” between an intervention of the new architecture and the previously existing architecture. A relationship determined strictly by linguistic considerations, to his understanding, in harmony with all of the architectural production of the XXth century. From Contrast to Analogy would summarise transformations in the discursive perception of architectural intervention, as a changing phenomenon depending on cultural values, but at the same time, showing a clear dialogical tendency between two formal categories: Contrast, emphasising the possibilities of novelty and difference; and on the other hand the emerging Analogy, as a new awareness of interpretation of the ancient building, where the similarity and diversity are manifested simultaneously. For Solá-Morales the analogical procedure is not based on the visible simultaneity of formal orders, but on associations that the subject establishes throughout time. Through analogy it is tried to overcome the simple visual relationship with the antique, to focus on its spacial, physical and geographical nature. If the analogical attempt guides an opening towards a new continuity; it still persists in the connection of dimensional, typological and figurative factors, subordinate to the formal hierarchy of the preexisting subjects. 16 The reflexive contribution of Solá-Morales’ works could be final, if in the last decades before the end of the century there had not been certain changes regarding linguistic expression, encouraged by architecture, towards a kind of figurative hypertrophy, amongst many arguments we are in this case interested in three moments: The dissolution of the compositional consistency and the united style, the volumetric incorporation of the project as a reactive mechanism, and the change of the vision from retrospective towards prospective that the new conservation suggests. The recurrence to the history of architecture and its recognisable forms, as a way of perpetuating memory and establishing a reference, dissolved any instinct of compositive unity and style, provoking permanent relationships to tend to disappear. The composition and coherence lead to suppose a type of discontinuity of isolated objects in which only possible relationships could appear; no longer as an order of certain formal and compositive rules, but as a special way of setting elements in a specific work. The new globalised field required new forms of consistency between the project and the pre-existent subject, motivated amongst others by the higher pace of market evolution, increase of consumer tax and the level of information and competence between different locations; aspects which finally made stylistic consistence inefficient. In this context of disintegration, the project, in incorporation as well as added to a constructed building, stops being considered as a volumetric appendix subordinate to compositive and formal rules of old, to be considered as an organism of reactive order, that causes a change in the structural and systematic configuration of the existing foundation. The extension, previsouly spatial, is now considered a sensorial and morphological extension, with the implementation of technology and hyper-information, but at the same time, marked by a strong tendency of energetic optimization in its operational role, facing the emergence of the ecological factor in contemporary production. The technological world turns into a new nature, a nature that should be analysed from ecological terms; in other words, as an event of transition in the continuous redistribution of energy. In this area, effectiveness is not only determined by the capacity of adaptation to changing conditions, but also by its transforming capacity “expressly” in order to change an environment. In a society, like ours, that is modernising intensively, it is difficult to share an adecuate agreement with the forms of the past. From 1790, the date of the first French convention for the conservation of monuments, the scale of what is expexted to be preserved is more and more ambitious, so much so that nowadays the repertoire of that what is conserved includes practically all typologies of the constructed surroundings. For Koolhaas, the ínterval between the object and the moment when its conservation is decided has been reduced, from two 17 milennia in 1882 to a few decades nowadays. Shortly this lapse will disappear, showing a radical change of retrospective towards prospective, that is to say, that soon it will be necessary to decide what to conserve before constructing. The shapes of cities are the result of the continuous incorporation of architecture, and perhaps that only through architecture the response to the universe can be understood, the continuity of what has already been constructed. Our work is understood also within that system, modifying the field of action and leaving the road ready for the next movement of those that will follow after us. Continuity does not mean conservatism, continuity means being conscient of the transitory value of our answers to specific needs, accepting the change that we have received. That what has been constructed to remain and last, should cause future interventions to be integrated in it. It is necessary to accept continuity as a rule. Solá-Morales, in his time, distinguished between the relationship with new and old, between contrast and analogy. Today, almost three decades later, the objective consists of evaluating whether the model of architectural intervention in the constructed has been maintained since then or if new ways of positioning the project regarding the constructed have appeared. Our work claims to show the change of the approach of projects with pre-existing subjects and that this has got a close relation to the incorporation of new concepts, techniques, tools and necessities that impress the cultural context, caused by the change of centuries. This assumption guides us to establish a parallelism between the forms of connection where that what is new is manifested between a commonly assumed (topical), generic and orthodox position, based on that what is visual and expressive in the last decades of the XXth century, and an emerging (heterotopical), extraordinary and heterodox reality that stimulates the immaterial and that seems to emerge with growing intensity in the XXIst century. If throughout the XXth century the project of architectural intervention was considered from the continuity and discontinuity of formal categories, marked by the expression of the pre-existing building, the new contemporary intervention, as a reactive device in the landscape and territory, demands an absolute continuity. No longer a visual, expressive or functional one but a morphological continuity of adaptation and change with its own territorial dynamics, under new game rules and unfolding new operative (projective) strategies from its own logic and contingency. 18 The aim of this research is to determine new forms of continuity and the possible logic of production that are expressed in the Architectural Intervention, trying to overcome the obviousness of its physical and visual relationship, at the beginning of this new century, as a result of the incorporation of the operative factor that the new architectural device unfolds. We think it is correct to maintain the connotative path that marks the name architectural intervention by bringing previous concepts and theorical approaches that have been evolving through time together. If the name suffers from a wider operational range because of its formulation, a quality that our contemporary logic provokes, the reformulation and consolidation of an interventional concept could be more suitable for our times, giving preference to a logical method from its own necessity and contingency. It seems that now time shapes the topics, it is no longer about materialising a certain time but about expressing the changes that its new temporality generates. Finally, our initial approach aspires to form a new way of reflection that permits us to understand the complex implications that the new architecture submits the pre-existing subject to, motivated by the incorporation of factors external to simple formal and expressive judgement, prevailing at the end of the XXth century. In the same way, our set road, as an alternative, permits the contemplation of possible research paths, considering that what is pre-existing as an area that spans the whole territory with emerging changing dynamics and, with them, their interventional logics.

The protein product of the het-s heterokaryon incompatibility gene of the fungus Podospora anserina behaves as a prion analog

The het-s locus of Podospora anserina is a heterokaryon incompatibility locus. The coexpression of the antagonistic het-s and het-S alleles triggers a lethal reaction that prevents the formation of viable heterokaryons. Strains that contain the het-s allele can display two different phenotypes, [Het-s] or [Het-s*], according to their reactivity in incompatibility. The detection in these phenotypically distinct strains of a protein expressed from the het-s gene indicates that the difference in reactivity depends on a posttranslational difference between two forms of the polypeptide encoded by the het-s gene. This posttranslational modification does not affect the electrophoretic mobility of the protein in SDS/PAGE. Several results suggest a similarity of behavior between the protein encoded by the het-s gene and prions. The [Het-s] character can propagate in [Het-s*] strains as an infectious agent, producing a [Het-s*] → [Het-s] transition, independently of protein synthesis. Expression of the [Het-s] character requires a functional het-s gene. The protein present in [Het-s] strains is more resistant to proteinase K than that present in [Het-s*] mycelium. Furthermore, overexpression of the het-s gene increases the frequency of the transition from [Het-s*] to [Het-s]. We propose that this transition is the consequence of a self-propagating conformational modification of the protein mediated by the formation of complexes between the two different forms of the polypeptide.

Complexities in the genetic structure of Anopheles gambiae populations in west Africa as revealed by microsatellite DNA analysis

Chromosomal forms of Anopheles gambiae, given the informal designations Bamako, Mopti, and Savannah, have been recognized by the presence or absence of four paracentric inversions on chromosome 2. Studies of karyotype frequencies at sites where the forms occur in sympatry have led to the suggestion that these forms represent species. We conducted a study of the genetic structure of populations of An. gambiae from two villages in Mali, west Africa. Populations at each site were composed of the Bamako and Mopti forms and the sibling species, Anopheles arabiensis. Karyotypes were determined for each individual mosquito and genotypes at 21 microsatellite loci determined. A number of the microsatellites have been physically mapped to polytene chromosomes, making it possible to select loci based on their position relative to the inversions used to define forms. We found that the chromosomal forms differ at all loci on chromosome 2, but there were few differences for loci on other chromosomes. Geographic variation was small. Gene flow appears to vary among different regions within the genome, being lowest on chromosome 2, probably due to hitchhiking with the inversions. We conclude that the majority of observed genetic divergence between chromosomal forms can be explained by forces that need not involve reproductive isolation, although reproductive isolation is not ruled out. We found low levels of gene flow between the sibling species Anopheles gambiae and Anopheles arabiensis, similar to estimates based on observed frequencies of hybrid karyotypes in natural populations.

On the coefficients of the characteristic series of the U-operator

A conceptual proof is given of the fact that the coefficients of the characteristic series of the U-operator acting on families of overconvegent modular forms lie in the Iwasawa algebra.

The Impact of Language Opacity and Proficiency on Reading Strategies in Bilinguals: An Eye Movement Study

Reading strategies vary across languages according to orthographic depth - the complexity of the grapheme in relation to phoneme conversion rules - notably at the level of eye movement patterns. We recently demonstrated that a group of early bilinguals, who learned both languages equally under the age of seven, presented a first fixation location (FFL) closer to the beginning of words when reading in German as compared with French. Since German is known to be orthographically more transparent than French, this suggested that different strategies were being engaged depending on the orthographic depth of the used language. Opaque languages induce a global reading strategy, and transparent languages force a local/serial strategy. Thus, pseudo-words were processed using a local strategy in both languages, suggesting that the link between word forms and their lexical representation may also play a role in selecting a specific strategy. In order to test whether corresponding effects appear in late bilinguals with low proficiency in their second language (L2), we present a new study in which we recorded eye movements while two groups of late German-French and French-German bilinguals read aloud isolated French and German words and pseudo-words. Since, a transparent reading strategy is local and serial, with a high number of fixations per stimuli, and the level of the bilingual participants' L2 is low, the impact of language opacity should be observed in L1. We therefore predicted a global reading strategy if the bilinguals' L1 was French (FFL close to the middle of the stimuli with fewer fixations per stimuli) and a local and serial reading strategy if it was German. Thus, the L2 of each group, as well as pseudo-words, should also require a local and serial reading strategy. Our results confirmed these hypotheses, suggesting that global word processing is only achieved by bilinguals with an opaque L1 when reading in an opaque language; the low level in the L2 gives way to a local and serial reading strategy. These findings stress the fact that reading behavior is influenced not only by the linguistic mode but also by top-down factors, such as readers' proficiency.

Professionals, discretion and public sector reform in the UK:re-visiting Lipsky

Purpose – Seeks to examine how far Michael Lipsky's theory of discretion as it relates to public sector professionals as “street-level bureaucrats” is still applicable in the light of public sector reform and in particular the introduction of increased managerial control over professionals. Design/methodology/approach – The main thesis in Lipsky's work, Street-Level Bureaucracy, that street-level bureaucrats devise their own rules and procedures to deal with the dilemmas of policy implementation is linked to public sector reform over the past 25 years or so. The article differentiates between three forms of discretion, rule, task and value and assesses the extent to which these different forms of discretion have been compromised by reform. Examples are drawn principally from the literature on school teachers and social workers Findings – The findings suggest that the rule-making (hence bureaucratic) capacity of professionals at street-level is much less influential than before although it is questionable whether or not the greater accountability of professionals to management and clarity of the targets and objectives of organisations delivering public policy has liberated them from the dilemmas of street-level bureaucracy. Research limitations/implications – The work has focussed on the UK and in particular on two professions. However, it may be applied to any country which has undergone public sector reform and in particular where “new public management” processes and procedures have been implemented. There is scope for in-depth studies of a range of occupations, professional and otherwise in the UK and elsewhere. Practical implications – Policy makers and managers should consider how far the positive aspects of facilitating discretion in the workplace by reducing the need for “rule-making” to cope with dilemmas have been outweighed by increased levels of bureaucracy and the “de-skilling” of professionals. Originality/value – Lipsky's much cited and influential work is evaluated in the light of public sector reform some 25 years since it was published. The three forms of discretion identified offer the scope for their systematic application to the workplace.

β-Amyloid (Aβ) deposition in elderly non-demented patients and patients with Alzheimer's disease

β-amyloid (Aβ) deposition in the medial temporal lobe (MTL) was studied in elderly non-demented (ND) cases and in patients with Alzheimer's disease (AD). In AD, Aβ deposits were present throughout the MTL although density was less in the hippocampus than the adjacent cortical regions. In the ND cases, no Aβ deposits were recorded in 6 cases and in the remaining 8 cases, Aβ deposits were confined to the cortical regions adjacent to the hippocampus. The mean density of Aβ deposits in the cortical regions examined was greater in AD than in the ND cases but there was a significant overlap between the two groups. The ratio of mature to diffuse Aβ deposits was greater in the ND than the AD cases. In both patient groups, Aβ deposits formed clusters in the cortex and many tissues exhibited a regular distribution of clusters along the cortex parallel to the pia. The mean dimension of the Aβ clusters was greater in AD than in the ND cases. Hence, few aspects of Aβ deposition appeared to consistently separate AD from ND cases. However, the spread of Aβ pathology between modular units of the cortex and into regions of the hippocampus could be factors in the development of AD. © 1994.

Job satisfaction and organizatinal commitment in Greece

In Study 1 this research investigated research hypotheses based on the moderating role of the economic sector to job satisfaction/organizational commitment relationships, and especially to the forms of commitment and the facets of satisfaction – extrinsic satisfaction and intrinsic satisfaction. Overall, 618 employees successfully completed the questionnaires (258 from private sector companies and 360 from the public administration). Then, distinguishable organizational commitment profiles developed and constructed from the forms or constructs of commitment. Two different samples were used in Study 2 in order to test the relevant hypotheses – 1,119 employees from the private sector and 476 from the public sector. Study 3 used the concept of regulatory focus, where the two foci relate differently to forms of organizational commitment and these two states moderate the satisfaction/commitment relationship and furthermore, individuals develop four separable regulatory focus characters based on the two major regulatory foci. Moreover, the moderating intervention is crucially influenced by the employment status of the individuals. The research hypotheses developed in this part were tested through two samples of employees: 258 working in the private sector and 263 in the public sector. Study 4 examined the mediating role of job satisfaction on the organizational commitment/organizational citizenship behaviours relationship. It argued that job satisfaction mediates more strongly the relationship between these forms and loyal boosterism (one of the OCB dimensions). The relevant hypotheses were tested through a combined sample of 646 employees, equally drawn from the two sectors.
