Is a General Theory of Socially Disapproved Violence Possible (or Necessary)?

A model of theoretical science is set forth to guide the formulation of general theories around abstract concepts and processes. Such theories permit explanatory application to many phenomena that are not ostensibly alike, and in so doing encompass socially disapproved violence, making special theories of violence unnecessary. Though none is completely adequate for the explanatory job, at least seven examples of general theories that help account for deviance make up the contemporary theoretical repertoire. From them, we can identify abstractions built around features of offenses, aspects of individuals, the nature of social relationships, and different social processes. Although further development of general theories may be hampered by potential indeterminacy of the subject matter and by the possibility of human agency, maneuvers to deal with such obstacles are available.

Gender in Theology and Religion: a Success Story?! Report from a Conference

In January 2011 some fifty scholars from different parts of Europe met in Groningen, the Netherlands for an expert meeting entitled Gender in theology and religion: a success story?! to analyze the factors that contribute to the successful mainstreaming of gender in a theological discipline and to reflect on the future of gender studies in theology and religious studies. Different speakers highlighted the many successes of gender studies in theology and religious studies: its power to 'trouble' the disciplines and their heuristic categories; its contribution to the development of other disciplines such as queer studies and postcolonial studies; the many PhD studies produced; the number of significant publications that had appeared over the last years. All indicate that gender studies in theology and religious studies have matured. But the participants also pointed towards the ambiguity of the success of gender studies in the academy: the indeterminacy of the institutional position and positions of gender studies in the theological disciplines in seminaries, departments faculties and universities; the lack of male scholars’ engagement in gender studies, which is expressed by their absence in these studies and/or the low reception of gender studies publications in their disciplines. Both ambiguities represent a danger for the future of gender studies, according to the participants in the meeting. In order to further the success of gender in theology and religion they formulated the following recommendations: to analyze the position of these studies in their institutions from the perspective of the implied audience (church, academy, ordinary theologians); engage men in gender studies; embrace the cultural turn in religious studies; develop interdisciplinary cooperations with gender studies in the humanities; engage creatively with the changing role of religion in contemporary society; analyze whose perspective one follows and authorizes in the perception of theology, religious studies and gender studies themselves; record the history of women’s and gender studies in theology and religion, and honor and celebrate the successes.

Decision strategies for policy decisions under uncertainties: The case of mitigation measures addressing methane emissions from ruminants

Decision strategies aim at enabling reasonable decisions in cases of uncertain policy decision problems which do not meet the conditions for applying standard decision theory. This paper focuses on decision strategies that account for uncertainties by deciding whether a proposed list of policy options should be accepted or revised (scope strategies) and whether to decide now or later (timing strategies). They can be used in participatory approaches to structure the decision process. As a basis, we propose to classify the broad range of uncertainties affecting policy decision problems along two dimensions, source of uncertainty (incomplete information, inherent indeterminacy and unreliable information) and location of uncertainty (information about policy options, outcomes and values). Decision strategies encompass multiple and vague criteria to be deliberated in application. As an example, we discuss which decision strategies may account for the uncertainties related to nutritive technologies that aim at reducing methane (CH4) emissions from ruminants as a means of mitigating climate change, limiting our discussion to published scientific information. These considerations not only speak in favour of revising rather than accepting the discussed list of options, but also in favour of active postponement or semi-closure of decision-making rather than closure or passive postponement.

Contradictio in terminis: dialéctica de la ambigüedad en la arquitectura contemporánea

The twentieth century brought a new sensibility characterized by the discredit of cartesian rationality and the weakening of universal truths, related with aesthetic values as order, proportion and harmony. In the middle of the century, theorists such as Theodor Adorno, Rudolf Arnheim and Anton Ehrenzweig warned about the transformation developed by the artistic field. Contemporary aesthetics seemed to have a new goal: to deny the idea of art as an organized, finished and coherent structure. The order had lost its privileged position. Disorder, probability, arbitrariness, accidentality, randomness, chaos, fragmentation, indeterminacy... Gradually new terms were coined by aesthetic criticism to explain what had been happening since the beginning of the century. The first essays on the matter sought to provide new interpretative models based on, among other arguments, the phenomenology of perception, the recent discoveries of quantum mechanics, the deeper layers of the psyche or the information theories. Overall, were worthy attempts to give theoretical content to a situation as obvious as devoid of founding charter. Finally, in 1962, Umberto Eco brought together all this efforts by proposing a single theoretical frame in his book Opera Aperta. According to his point of view, all of the aesthetic production of twentieth century had a characteristic in common: its capacity to express multiplicity. For this reason, he considered that the nature of contemporary art was, above all, ambiguous. The aim of this research is to clarify the consequences of the incorporation of ambiguity in architectural theoretical discourse. We should start making an accurate analysis of this concept. However, this task is quite difficult because ambiguity does not allow itself to be clearly defined. This concept has the disadvantage that its signifier is as imprecise as its signified. In addition, the negative connotations that ambiguity still has outside the aesthetic field, stigmatizes this term and makes its use problematic. Another problem of ambiguity is that the contemporary subject is able to locate it in all situations. This means that in addition to distinguish ambiguity in contemporary productions, so does in works belonging to remote ages and styles. For that reason, it could be said that everything is ambiguous. And that’s correct, because somehow ambiguity is present in any creation of the imperfect human being. However, as Eco, Arnheim and Ehrenzweig pointed out, there are two major differences between current and past contexts. One affects the subject and the other the object. First, it’s the contemporary subject, and no other, who has acquired the ability to value and assimilate ambiguity. Secondly, ambiguity was an unexpected aesthetic result in former periods, while in contemporary object it has been codified and is deliberately present. In any case, as Eco did, we consider appropriate the use of the term ambiguity to refer to the contemporary aesthetic field. Any other term with more specific meaning would only show partial and limited aspects of a situation quite complex and difficult to diagnose. Opposed to what normally might be expected, in this case ambiguity is the term that fits better due to its particular lack of specificity. In fact, this lack of specificity is what allows to assign a dynamic condition to the idea of ambiguity that in other terms would hardly be operative. Thus, instead of trying to define the idea of ambiguity, we will analyze how it has evolved and its consequences in architectural discipline. Instead of trying to define what it is, we will examine what its presence has supposed in each moment. We will deal with ambiguity as a constant presence that has always been latent in architectural production but whose nature has been modified over time. Eco, in the mid-twentieth century, discerned between classical ambiguity and contemporary ambiguity. Currently, half a century later, the challenge is to discern whether the idea of ambiguity has remained unchanged or have suffered a new transformation. What this research will demonstrate is that it’s possible to detect a new transformation that has much to do with the cultural and aesthetic context of last decades: the transition from modernism to postmodernism. This assumption leads us to establish two different levels of contemporary ambiguity: each one related to one these periods. The first level of ambiguity is widely well-known since many years. Its main characteristics are a codified multiplicity, an interpretative freedom and an active subject who gives conclusion to an object that is incomplete or indefinite. This level of ambiguity is related to the idea of indeterminacy, concept successfully introduced into contemporary aesthetic language. The second level of ambiguity has been almost unnoticed for architectural criticism, although it has been identified and studied in other theoretical disciplines. Much of the work of Fredric Jameson and François Lyotard shows reasonable evidences that the aesthetic production of postmodernism has transcended modern ambiguity to reach a new level in which, despite of the existence of multiplicity, the interpretative freedom and the active subject have been questioned, and at last denied. In this period ambiguity seems to have reached a new level in which it’s no longer possible to obtain a conclusive and complete interpretation of the object because it has became an unreadable device. The postmodern production offers a kind of inaccessible multiplicity and its nature is deeply contradictory. This hypothetical transformation of the idea of ambiguity has an outstanding analogy with that shown in the poetic analysis made by William Empson, published in 1936 in his Seven Types of Ambiguity. Empson established different levels of ambiguity and classified them according to their poetic effect. This layout had an ascendant logic towards incoherence. In seventh level, where ambiguity is higher, he located the contradiction between irreconcilable opposites. It could be said that contradiction, once it undermines the coherence of the object, was the better way that contemporary aesthetics found to confirm the Hegelian judgment, according to which art would ultimately reject its capacity to express truth. Much of the transformation of architecture throughout last century is related to the active involvement of ambiguity in its theoretical discourse. In modern architecture ambiguity is present afterwards, in its critical review made by theoreticians like Colin Rowe, Manfredo Tafuri and Bruno Zevi. The publication of several studies about Mannerism in the forties and fifties rescued certain virtues of an historical style that had been undervalued due to its deviation from Renacentist canon. Rowe, Tafuri and Zevi, among others, pointed out the similarities between Mannerism and certain qualities of modern architecture, both devoted to break previous dogmas. The recovery of Mannerism allowed joining ambiguity and modernity for first time in the same sentence. In postmodernism, on the other hand, ambiguity is present ex-professo, developing a prominent role in the theoretical discourse of this period. The distance between its analytical identification and its operational use quickly disappeared because of structuralism, an analytical methodology with the aspiration of becoming a modus operandi. Under its influence, architecture began to be identified and studied as a language. Thus, postmodern theoretical project discerned between the components of architectural language and developed them separately. Consequently, there is not only one, but three projects related to postmodern contradiction: semantic project, syntactic project and pragmatic project. Leading these projects are those prominent architects whose work manifested an especial interest in exploring and developing the potential of the use of contradiction in architecture. Thus, Robert Venturi, Peter Eisenman and Rem Koolhaas were who established the main features through which architecture developed the dialectics of ambiguity, in its last and extreme level, as a theoretical project in each component of architectural language. Robert Venturi developed a new interpretation of architecture based on its semantic component, Peter Eisenman did the same with its syntactic component, and also did Rem Koolhaas with its pragmatic component. With this approach this research aims to establish a new reflection on the architectural transformation from modernity to postmodernity. Also, it can serve to light certain aspects still unaware that have shaped the architectural heritage of past decades, consequence of a fruitful relationship between architecture and ambiguity and its provocative consummation in a contradictio in terminis. Esta investigación centra su atención fundamentalmente sobre las repercusiones de la incorporación de la ambigüedad en forma de contradicción en el discurso arquitectónico postmoderno, a través de cada uno de sus tres proyectos teóricos. Está estructurada, por tanto, en torno a un capítulo principal titulado Dialéctica de la ambigüedad como proyecto teórico postmoderno, que se desglosa en tres, de títulos: Proyecto semántico. Robert Venturi; Proyecto sintáctico. Peter Eisenman; y Proyecto pragmático. Rem Koolhaas. El capítulo central se complementa con otros dos situados al inicio. El primero, titulado Dialéctica de la ambigüedad contemporánea. Una aproximación realiza un análisis cronológico de la evolución que ha experimentado la idea de la ambigüedad en la teoría estética del siglo XX, sin entrar aún en cuestiones arquitectónicas. El segundo, titulado Dialéctica de la ambigüedad como crítica del proyecto moderno se ocupa de examinar la paulatina incorporación de la ambigüedad en la revisión crítica de la modernidad, que sería de vital importancia para posibilitar su posterior introducción operativa en la postmodernidad. Un último capítulo, situado al final del texto, propone una serie de Proyecciones que, a tenor de lo analizado en los capítulos anteriores, tratan de establecer una relectura del contexto arquitectónico actual y su evolución posible, considerando, en todo momento, que la reflexión en torno a la ambigüedad todavía hoy permite vislumbrar nuevos horizontes discursivos. Cada doble página de la Tesis sintetiza la estructura tripartita del capítulo central y, a grandes rasgos, la principal herramienta metodológica utilizada en la investigación. De este modo, la triple vertiente semántica, sintáctica y pragmática con que se ha identificado al proyecto teórico postmoderno se reproduce aquí en una distribución específica de imágenes, notas a pie de página y cuerpo principal del texto. En la columna de la izquierda están colocadas las imágenes que acompañan al texto principal. Su distribución atiende a criterios estéticos y compositivos, cualificando, en la medida de lo posible, su condición semántica. A continuación, a su derecha, están colocadas las notas a pie de página. Su disposición es en columna y cada nota está colocada a la misma altura que su correspondiente llamada en el texto principal. Su distribución reglada, su valor como notación y su posible equiparación con una estructura profunda aluden a su condición sintáctica. Finalmente, el cuerpo principal del texto ocupa por completo la mitad derecha de cada doble página. Concebido como un relato continuo, sin apenas interrupciones, su papel como responsable de satisfacer las demandas discursivas que plantea una investigación doctoral está en correspondencia con su condición pragmática.

How vague can your patent be? Vagueness strategies in U.S. patents

Patent claims defi ne the protection scope of the intellectual property sought by the patent applicant or patentee. Broad claims are valuable as they can describe more expansive rights to the invention. Therefore, if these claims are too broad a potential infringer will more easily argue against them. But if the claims are too narrow the scope of protection of the intellectual property is greatly reduced. Patent claims have to be, on the one hand, determinate and precise enough and, on the other hand, as inclusive as possible. Therefore patent applicants must fi nd a balance in the broadness of the scope defi ned by their claims. This balance can be achieved by the choice of words with a convenient degree of semantic indeterminacy, by the choice of modifi ers or other strategies. In fact, vagueness in patent claims is a desirable characteristic for such documents. A quantitative and qualitative analysis of a corpus of 350 U.S. patents provides a promising starting point to understand the linguistic instruments used to achieve the balance between property claim scope and precision of property description. To conclude, some issues relating vagueness and pragmatics are suggested as a line of further research.

Sobre la Arquitectura en la definición del Paisaje

Comúnmente la Arquitectura se manifiesta en los edificios como un hecho de la realidad que tiene siempre carácter contemporáneo y ése debe ser el valor supremo de un arte que no distingue entre antiguo y moderno, por afectar al presente y ser contemporáneo como experiencia. Los objetos se insertan irremediablemente en su medio e incluso llegan a definirlo en ocasiones: así, arquitectura y paisaje, aparecerán a veces confundidos con diferencias difíciles de determinar. El término “paisaje” es relativamente moderno y se deriva de ciertas representaciones gráficas o pictóricas producidas en Occidente en época algo posterior al Renacimiento. No obstante, el hecho de que una palabra se pueda escribir o se cite no quiere decir que la realidad a la que responde no pueda existir, pues lo escrito es solamente un medio de expresión, y es obvio que existen otros quizá más antiguos y de idéntica importancia, pues la propia escritura no es más que el reflejo de un fenómeno que ya se ha producido con anterioridad. Parece así que el testimonio de la realidad viene dado por distintos contextos en lo que suele llamarse “cultura” de modo que las culturas pueden tener aspectos de gran interés mediante diferentes sistemas de expresión variados sin que eso tenga que pasar forzosamente por el filtro de un alfabeto y una escritura. A tenor de los primeros descubrimientos, parece que la cuestión de escribir tuvo originalmente un carácter de constatación de apunte contable y tampoco se puede establecer con certeza si algunos utilizaron la escritura como el so-porte adecuado para referir mitos o historias, pues la Arqueología no ha proporcionado sino testimonios fragmentarios; de lo que si está repleta sin duda la historia es de apuntes contables. Otra cuestión que suscita dudas es la propia definición de escritura, pues parece que los más antiguos modos de expresión escrita se reducen a pictogramas que resultan aún indescifrables. Lenguas y toponimia son también herramientas muy útiles para bucear en el pasado, pero aún así persisten dudas en las escrituras que pro-vienen de las representaciones primordiales: la propia escritura en sus orígenes parece alimentarse de las propias intuiciones inmediatas de la representación, algo que evolucionaría representando esa realidad urgente e inmediata del control o el abastecimiento que luego se convertirían en los fragmentos de texto que han podido conservarse. Es notorio, sin embargo, que ese conjunto enorme de convenios gráficos estaba sujeto a la palabra y la desaparición de las culturas determinó también la desaparición consecuente de sus lenguas, y esos signos - fueran o no escritura - han pasado definitivamente a las zonas oscuras del conocimiento. Escribir supone también disponer de capacidad de abstracción gráfica que diferencie la palabra y la cosa, y es posible que la razón que llevara a ese descubrimiento fuera simplemente el de una economía de signos, pues escritura y lenguaje son limitados por definición, mientras que las cosas del mundo son innumerables: ningún idioma contiene todas las palabras para describir todo lo que puede aparecer. Aparentemente, ese el motivo por el cual existe un localismo – un término específico que refiere algo que existe en un lugar y no en otros - en lo que se refiere a dar el nombre a la cosa y también fuente de paradigma entre los pueblos que se consideran primitivos y los que se consideran civilizados. Debe tenerse en cuenta también que esa transposición se da en ambos sentidos, de modo que las culturas más aisladas también incorporan conceptos que carecen de una explicación racional consistente. Las mitologías son así eternas, pues sirven para explicar realidades que carecen de un entendimiento alcanzable y está también bastante claro que los lenguajes resultan ser un enigma, como realidad autónoma que queda en-cerrada y se explica en sí misma. Parece también que los primeros en escribir las consonantes aisladas fueron los pueblos semíticos occidentales de las orillas del Mediterráneo, pueblos que crearon un alfabeto silábico que llegó a ser utilizado incluso por los tartesios en el sur de la península ibérica como el primer alfabeto de toda Europa occidental. Resulta patente que el término “paisaje” se ha nutrido siempre de representaciones, bien escritas o artísticas, pero queda también claro que esas representaciones se suponen derivadas de la creencia en una idea de paisaje como algo que se ve representado en sí mismo, es decir, como la imagen de una realidad externa situada fuera del individuo. Eso es un hecho trascendente, pues el paisaje requiere lejanía de la cosa, de modo que el actor – aún sabiéndose inserto en su paisaje – es incapaz de percibirlo desde dentro. En el paisaje ocurre igual que en un teatro o en una representación: los actores son conscientes de su papel y su posible cometido, pero no son los que realmente pueden disfrutar de la eficacia o de la propia presencia de la obra, pues forman parte de ella. La idea de paisaje proviene de una lectura externa a la de los propios protagonistas del drama, de modo que si quieren ser un crítico del paisaje se debe abandonar la representación para mirar el espectáculo desde una distancia adecuada, al fin y a cabo externa. De ese modo, aparece la primera constatación del hecho del paisaje como una realidad construida por objetos y personajes, pero, sobre todo, es una realidad construida por miradas. Llama también la atención otorgada en las lecturas de los especialistas hacia esa referencia externa - artística si se quiere - sobre el término “paisaje”, de modo que la bibliografía no especializada sobre el particular siempre acaba en tratados de pintura o poesía. Parece sin embargo que el hombre y sus paisajes son realidades indisolubles desde la propia aparición de la especie, de modo que llevar la cuestión hacia términos exclusivamente esteticistas parece una posición parcial. Hombre y medio han formado siempre una sola unidad, aunque esa unidad se haya convertido en determinados casos en sinónimo de depredación y destrozo. Sin embargo, esa destrucción crea igualmente un paisaje como desolación que es resultado del propio quehacer del hombre: elementos que también poseen un contenido sustancial de memoria en los paisajes industriales como un momento de la Historia previo a la automatización y a la globalización de la vida actuales. Quizá el concepto más interesante desde el punto de vista teórico sea precisamente el de esa cualidad del paisaje como mirada, algo externo producido por el contemplador en un momento ajeno a la pertenencia, una mirada que no es tan sólo estética sino comprensiva, gozosa, activa o analítica - pues existen tantas maneras de mirar como sujetos - sin que pueda definirse con precisión esa contemplación más que en términos que alcanzan la propia individualidad. En términos poéticos, también podría establecerse como ese conjunto de miradas individuales crean también una estructura que hace que ese paisaje se valore y se comprenda, de modo que desde ese punto de vista ese paisaje supone una creación colectiva. Con respeto o como depredador, el hombre se ha instalado en su medio, y al hacerlo, ha dejado huellas dentro del propio paisaje que hacen que tome una determinada significación. Naturalmente, existe una teoría que distingue entre “país” y “paisaje”, asumiendo para el primero la noción exclusiva de territorio en la cual el hombre no tiene papel estético alguno. He intentado muchas veces comprender esa posición, sin acabar de entender el planteamiento que la sustenta: parece que la visión de la cosa estará siempre humanizada, aún en las zonas “vírgenes” o intactas, pues la propia visión hace que el objeto se modifique en su propia unidad perceptiva, creando una curiosa indeterminación que lleva a los conocidos equívocos entre imagen real y representación. Efectivamente, la visión de la cosa requiere de una cultura y unos medios que la informan, de modo que un texto, una pintura, una descripción o una fotografía quedarán ya humanizadas por el propio hecho de ser informadas, pues ello otorga una forma a priori. De ese modo, el paisaje figura inscrito en una función que establece tanto aspectos de un paisaje posible como aspectos del paisaje descrito y solamente podrá hablarse sobre la potencialidad del estado final de ese paisaje y nada del propio paisaje en sí, mientras ese paisaje no quede humanizado por el propio observador. Esta cuestión obliga a elegir una definición de paisaje alejada de presupuestos esteticistas para acercarla a los puramente culturales, de modo que no existe otra vía para la investigación que contemplar esa realidad física en función de las coordenadas del hombre que la habita, dotada del contenido correspondiente a esa revelación. Lejos de las posiciones de la geomorfología, el término “paisaje” implicará así unas condiciones determinadas de contemplación por parte de un sujeto por el cual el espectáculo queda humanizado en dicho acto.Cabe pensar también si no es cierto que todos los paisajes requieren de esa condición humanizada, pues aunque no estén habitados están siempre ocupados por esa mirada que los habita, al igual que un escenario sin público que carece de vigencia. A partir de ahí se sitúan las coordenadas en donde este trabajo configura la presencia de la arquitectura en la definición del paisaje, una premisa que parece ya venir otorgada desde el principio, pues esa misma mirada del espectador ya está dotando de un sentido de orden y jerarquía a la contemplación, unas cualidades que están en la base de toda actividad arquitectónica, De hecho la propia definición de “monumento natural” - en si misma una contradicción – expresa ese conflicto, dotado de un fenómeno de admiración y solape entre cultura y naturaleza, como conceptos enfrentados desde su origen. La conclusión sobre el dilema propuesta en la tesis no ha sido otra que suponer que esas dos realidades que son la cultura y el paisaje se han solapado desde el principio de los tiempos del hombre formando un binomio indeslindable. Se ha dicho antes que el proceso de invasión del territorio por el hombre es significativo, y esa significación es la que origina una creación autónoma que se aísla como un concepto abstracto de los entes naturales, tomándolos como material de trabajo, y estableciendo una oposición conceptual en la realidad perforada e interpretada por el hombre que viene a oponerse a lo que supone la caja cerrada e ignota del enigma del mundo. La cuestión de la significación del hombre sobre el territorio se subsume en la creación de unos productos que permanecen y que son testimonio de la propia cultura, de forma que la cantidad de rastro que el hombre deja sobre el territorio contribuye en mayor medida a la cualificación del paisaje como concepto. Eso lleva a establecer que cualquier paisaje - por el mero hecho de serlo y ser definido así – es ya cultural, puesto que está configurado por los productos de la cultura. Las palabras que puedan quedar encerradas en las piedras de los monumentos o de las ciudades son las de los hombres que trabajaron allí, y también las de los que las habitaron: más aún, el propio sentido del paisaje y su conservación vienen determinados por la presencia del hombre como único interprete de conceptos como ecología o conservación, algo que se pone de manifiesto también en la espantosa devastación que producen los fenómenos propios de la naturaleza. La historia natural, al igual que la vida, están conformadas por éxito y devastación, sin que uno y otra tengan especial preferencia, pues la preferencia se alimenta de otra clase de conceptos. La cuestión de atribuir valores morales al mundo natural es algo muy antiguo, y quizá sea la fuente o el manantial de las primeras religiones, una cuestión que se une a la indefectible noción de mortalidad que define la existencia del hombre frente a la inmanencia de la naturaleza. Esa propia naturaleza está dotada intuitivamente de un carácter “inocente” suponiendo que la inocencia es lo opuesto a la sabiduría. La cuestión es bien otra, ya que la naturaleza no posee ni siquiera algo que pueda definirse como “carácter”, en el sentido personal del término. La cuestión no cae, evidentemente, del lado de las definiciones o de las cualidades, sino del propio análisis de la realidad que el hombre va construyendo, destruyendo, embelleciendo o perjudicando para definir el territorio que habita, interponiendo a su manera recursos, instalaciones y en definitiva todos los testimonios posibles como principal manifestación de su esencia. Entre los artefactos que el hombre produce, uno de los más persistentes y más conspicuamente descritos es el de la arquitectura - entendida aquí en un sentido amplio - es decir, como el conjunto de modificaciones del espacio y del territorio. El espacio se puede modificar de muchos modos, pero en cualquiera de los casos constituye una de las huellas más características que el hombre establece como manifestación física de su propio ser discursivo. También la arquitectura ha demostrado ser una de los fenómenos más persistentes, incluso más que la propia lengua que la origina en su discurso primero antes que pueda ac-cederse a una idea sobre la conformación del material. Es paradigmático que el episodio descrito sobre la Torre de Babel en la Biblia la cuestión de la ambición de los hombres frente a Dios, representada precisamente en una arquitectura, se asimile a la discusión sobre el lenguaje primordial. La cuestión no es baladí, pues el fenómeno de la creación es algo que se concede exclusivamente a los dioses, que por esa razón habitan los territorios a los que los hombres no pueden llegar; territorios de albergue en los que las mitologías sitúan a dioses y demonios, con amplios espacios intermedios donde situar a las divinidades menores, héroes o seres híbridos en los que la coyunda de los dioses con los humanos produce sujetos que alivian el sentido de la mortalidad. El comentario del Génesis también concede un valor a la técnica, al mito de Prometeo y al fuego como creador de excelencia. Frente al progreso prometeico, se postula el valor divino, y la única forma posible de paliar ese progreso es la confusión del lenguaje, pues eso será lo que produzca la dispersión y la falta de acuerdo. La cuestión también puede explicar esa afición tan común por lo canónico en arquitectura que se mantiene a lo largo de grandes períodos, al igual que una gran máquina de inercia. Parece que los conceptos primordiales de la arquitectura basados en elementos simples como el hito, el dintel, lo recto y lo curvo, la rampa o la escalera, y el uso distinto o cualificado que se otorga a la piedra, el ladrillo, la madera o el metal como componentes primordiales del material arquitectónico se haya mantenido a lo largo de muchos milenios sin apenas cambios, al igual que ocurre con las costumbres alimenticias que siguen una progresión ascendente a través de lo crudo, lo asado y lo cocido, hasta obtener distintos grados de refina-miento, pero que siempre se sustentan en la sensación primigenia. El descubrimiento de la arquitectura proviene de un cierto manejo de las dimensiones, y consiguientemente de la geometría. Pero la geometría es cosa abstracta al igual que el lenguaje, de modo que para poder realizar arquitectura se hace necesaria esa capacidad de abstracción primera que luego permite la realización de un dispositivo. La realidad y su número exhiben un divorcio, al igual que las cosas y sus nombres exhiben el suyo, y el análisis numérico es solamente una forma de ver la realidad, una forma rigurosa y exacta – aunque parcial - que solamente representa el modelo ideal al cual la realidad se aproxima en mayor o menor medida: esa aproximación matemática hace que el universo pueda condensarse parcialmente en números, al igual que la realidad puede condensarse en nombres, pero ni el nombre ni el número reflejarán el mundo en toda su complejidad. El número es quizá solamente un medio de describir las cosas, como lo serían las formas puras que responden a una configuración matemática que pueda producirse en teoría en cualquier parte del Universo. Sin embargo, para el ejercicio de la arquitectura es preciso acudir a esa simplificación que exige la visión abstracta del plano como una sección cierta realidad como un corte abstracto del elemento considerado. Con su traza o sin ella, con la propia expresión matemática que lo describa o sin precisarla, esa intuición del plano como elemento generador del espacio es anterior a aquella expresión, al igual que el habla fue anterior a la escritura, pues solamente se produjo a través de ella y como refuerzo y sustituto de la memoria. Existen así abstracciones de la memoria que aparecen derivadas de los signos de la naturaleza aparecidos solamente de forma eventual y fragmentaría: así ocurre con la línea, el cuadrado y el círculo, formas iniciales y abstractas sonsacadas en cierta medida de la observación que dan origen a los primeros signos de la arquitectura primordial, de modo que cuadrados y círculos, elevados a prismas y superficies esféricas o esferoides aparecen en tumbas y edificios elementales de los primeros tiempos mediante una geometría primordial que se superpone al paisaje en el que se inserta. Es cierto también que esas formas se encuentran ya aproximadas en objetos que se encuentran en el medio físico, líneas en extremidades, ramas y miembros; ángulos rectos en algunos cristales que se observan mediante corte o formas circulares en astros y cráteres, pero esa realidad solamente presenta su forma aproximada y no su abstracción pura, de igual modo que el jeroglífico propondrá al ave rapaz para representar la idea de vigilancia y la buena vista, o incluso que la imagen del propio ojo sustituya la idea del Dios que todo lo ve en las culturas anti-guas. La elección fue resuelta, después de muchos intentos y aproximaciones, con la adopción del ángulo recto como un artificio fácil para el replanteo a través del triángulo sagrado 3:4:5 que ya se utilizó para construir las pirámides de Egipto, y que dio origen también a la mayor parte del urbanismo antiguo, coexistiendo con la forma circular primordial en el tipo denominado “tholo”. Aquella trama cuadrangular era uno de los patrones de relleno del espacio más comunes y compactos, y esa fue probablemente la razón por la que en tiempos muy posteriores fuera adoptada como una forma eficaz permanente de organización frente al desorden topológico que procura el conjunto de asociación de plantas circulares. Otra cuestión paradigmática es que esos conceptos primordiales e ignotos - que convergen en el mismo origen de las civilizaciones - se conviertan luego en algo canónico, a través del uso. El canon en sí mismo es algo ideal, como una norma aplicable a objetos de una realidad que ha sido creada solamente como indicio del ca-non, algo abstracto que tiene proporciones estrictas que son siempre las mismas y no obedece a criterios racionales: será absurdo sin embargo buscar el canon griego entre los templos de época como algunos lo hicieron, pues los edificios solamente se aproximan a los ejemplos canónicos y por esa razón se habla del “dórico del Partenón” que es diferente del de Egina o del de Paestum, siendo todos ellos evidentemente dóricos. Sin embargo, esa idea resulta útil al tratadista, al teórico de la arquitectura y al historiador, aun-que solamente refleje una vaga idea de lo que sucede más allá del tratado. Otra cuestión es la sutileza de los ejemplos de arquitectura, y del mismo modo que los cuerpos de los seres vivos jamás son simétricos, aunque respondan a un diseño simétrico general derivado de las condiciones de la división celular, los edificios supuestamente canónicos en los que los especialistas se inspiraron para definir los órdenes clásicos no disponen de esa simetría modular exacta, sino que adaptan un modelo general al lugar siempre cambiante del emplazamiento, es decir, se adaptan con habilidad a la vez que configuran el paisaje en el que se insertan. La luz de los distintos intercolumnios del Partenón es ligeramente distinta, aunque guarde un evidente sentido de simetría axial, de manera que aquellos “órdenes” que formaron la Teoría de la Arquitectura no son más que una bella interpretación sectorial de la arquitectura antigua elaborada por los tratadistas del Renacimiento y, posteriormente, por los neoclásicos. Parece, sin embargo, que ese ansia por el canon como claridad de lenguaje es algo consustancial al desarrollo de la arquitectura, una lingua franca que tiende a evitar la dispersión producida entre los mortales por los dioses antiguos, de modo que si no era posible llegar al cielo de los dioses se procuró que el lenguaje de la Tierra fuera al menos inteligible para poder entenderse entre los hombres. Parece que la estructura del poder siempre requirió de un determinado nivel de organización, y también que las instrucciones se entendieran con claridad: parece que en nuestros tiempos esos antiguos cánones se han sustituido por la obediencia a normas abstractas, dictadas por instituciones también algo abstractas y que tienen nombres divertidos compuestos por siglas, aunque no se conozca bien su virtud. El canon actual está constituido por “normas” que dejan tranquilos a algunos, aunque parece quizá que todo ese entramado formal que sirve como anestesia para el cuerpo social procura también la destrucción de los bosques en formas de montañas ingentes de papel burocrático. Durante muchos siglos las normas fueron otras, en la forma de un canon del cual nadie podía escapar: aún así, mediante la utilización de cánones o sin ellos, la arquitectura prosperó en la civilización desde los primeros refugios cavernarios o los abrigos primigenios y de ese modo fue configurando la realidad, es decir, el paisaje. Como antes se dijo, ese es un viaje de ida y vuelta en el cual ambos se confundían y subsumían: el manejo de las formas y lenguajes de la arquitectura posibilitaría con el tiempo la distinción entre el campo en donde reina el caos y la ciudad, en donde reina teóricamente el orden, creando un divorcio que duraría milenios y que aún persiste. Esa oposición generaría también una forma de paisaje y una serie de usos simbólicos y sagrados de los elementos de la arquitectura - como son puertas y murallas - que se han mantenido conceptualmente aunque hoy las ciudades ya no posean murallas físicas, ni puertas que se cierran con la llegada de la noche. En ese sentido, la arquitectura ha podido definir el paisaje, entendiendo la arquitectura no solamente como los edificios en sí, sino como el hecho de la manifestación del hombre sobre el territorio, de modo que no podrá hablarse de paisaje sin su arquitectura, del mismo modo que no puede hablarse de paisaje sin hombres. Por esta razón, la Tesis habla sobre Arquitectura y Paisaje, pero más particularmente sobre el hecho de la arquitectura en la definición del paisaje, es decir, de como los hechos arquitectónicos van a determinar o no la cualidad y la calificación de un paisaje. Deberá partirse en primer lugar de una definición de lo que se entiende y se ha entendido comúnmente por paisaje: igualmente, y habida cuenta del contexto en el que sitúa el propio trabajo de tesis, la cuestión solamente se circunscribirá a lo que se entiende como cultura occidental, pues el desarrollo de la civilización presenta siempre un color local que hace que el análisis de un fenómeno de esta envergadura tenga distintas connotaciones en las distintas áreas de civilización. De igual modo, y habida cuenta también que el paisaje se construye a través de todas las manifestaciones culturales, se hará a veces necesario indagar en otras disciplinas no arquitectónicas para comprender el alcance de algunos casos en los cuales los restos arquitectónicos han desaparecido, o en los que subsisten escasas trazas. Una definición tan amplia de la Arquitectura llevaría a escribir un relato sobre toda la cultura occidental y por ese motivo solamente se han esbozado ideas sobre la aparición de esos signos sobre el paisaje basados en elementos antiguos y primigenios que se repiten con insistencia y van dando lugar al variado repertorio de la arquitectura occidental cómo conformación de ideas sobre el me-dio y sobre el mundo que se percibe y se habita. ABSTRACT About Architecture in defining Landscape. Abstract Architecture is commonly manifested in buildings as a fact of reality that has always a contemporary character and that should be the highest value of an art that does not distinguish between ancient and modern, to affect the present and be contemporary as experience. Objects are inserted irremediably in their midst and even sometimes come to define it: thus, architecture and landscape, appear sometimes confused with differences difficult to determine. However, the term "landscape" is relatively modern and is derived from certain graphical or pictorial representations produced in the West in some subsequent period to the Renaissance. The fact that a word can be written or quoting does not mean that the reality that can not be answered, because the writing is only a mean of expression, and it is obvious that there are other and perhaps older equally important, because the writing itself is nothing more than the reflection of a phenomenon that has occurred before. It thus appears that the testimony of reality is given by different contexts in what is called "culture", so that cultures can have aspects of great interest by many different expression systems without this necessarily have to pass through the filter of alphabet and writing. Under the initial findings, it appears that the question of writing originally had a character and finding accounting entries, and it can not be established with certainty whether some used writing as the support appropriate to refer myths or stories, because archaeology has provided only fragmentary evidence. Another issue that raises questions is what can properly be defined as writing, it seems that the oldest modes are reduced to writing pictograms are still indecipherable. Languages and place names are also very useful tools for diving in the past, but still questions remain in the scriptures that come from the primordial representations: either it is very well defined what the own writing in its origins: the beginnings seem to feed on immediate intuitions of representation, which would evolve representing reality that urgent and immediate control or supply which is then inherited into fragments. It is noteworthy, however, that this huge set of graphics agreements was subject to the word and the disappearance of cultures determined also the consequent disappearance of their languages, and those signs - whether or not they write - have passed definitively to dark areas of knowledge. Writings supposed also the capacity of abstraction graph differentiates the word and the thing, and it is possible that the reason to carry this discovery was simply that of an economy of signs, for writing and language are limited by definition, while the things of the world are innumerable: no language contains all words to describe all that may appear. Apparently, that's why there is a localism - a specific term that refers to something that exists in one place and not in others - in regards to name the thing and also the source of paradigm among peoples are considered primitive and civilized. It should be noted also that transposition occurs in both directions, so that the most isolated cultures also incorporate concepts that lack a consistent rational explanation. Mythologies are eternal and therefore serve to explain realities that lack an understanding achievable and also pretty clear that languages happen to be an enigma, as an autonomous reality that is enclosed and explains itself. It also seems that the first to write consonants were isolated western Semitic peoples from the shores of the Mediterranean, peoples who created a syllabic alphabet came to be used even by tartesios in southern Iberia as the first alphabet in Western Europe. It is clear that the term "landscape" has always nurtured representations, either written or artis-tic, but it is also clear that these representations are assumed arising from belief in an idea of landscape as something that is represented in itself, as the image of a reality external located outside the individual. That is an important fact because the landscape requires remoteness of the thing, so that the actor - even knowing insert in landscape - is unable to perceive from within. The landscape is just as in a theatre or a performance: the actors are aware of their role and their possible role, but they are not the ones who can really enjoy the efficiency or the presence of the work itself, as part of it. The idea comes from an external landscape reading the principles of players in the drama, so if you want to be a critic of the landscape should leave the actual representation to watch the spectacle from a safe distance, finally external. Thus, the first finding of fact of the landscape appears as a reality constructed by objects and characters, but above all, a reality constructed by looks. Also noteworthy given the readings of specialists to the external reference - art if it could be - on the term "landscape", so no specialized literature on the subject always ends in treatises on painting or poetry. It seems however that the man and his landscapes are inseparable realities from the very onset of the species, so bring the issue into terms exclusively aesthetics seems a partial position. Man and environment have always been a single unit, but that unit has become synonymous with certain cases predation and destruction. Nevertheless, this destruction also creates a landscape as desolation that results from proper task of man elements that also have substantial contents of memory in industrial landscapes as a time of pre-automation history and globalization of current life. Perhaps the most interesting from a theoretical point of view is precisely that quality of landscape as something external produced by the viewer in a strange time of membership, a look that is not only aesthetic but sympathetic, joyful, active concept or analytical - because there are so many ways to look as subjects - it may not be precisely defined that contemplation rather than in terms that reach one's individuality. In poetic terms, it could also be set as the set of individual gazes also create a structure that makes this landscape is valued and understood, so from that point of view that landscape is a collective creation. With respect or as a predator, man has settled in his environment and in doing so has left traces in the landscape itself that make take a certain significance. Naturally, there is a theory that distinguishes what is "home" and what is "nature" providing for the first notion of the exclusive territory in which man has no aesthetic role. I tried many times to understand this position, without understanding the approach that supports: it seems that the vision of the thing is always humane, even in the "virgin" or untouched areas, as the vision itself makes the object modified in its own perceptual unit, creating a curious indeterminacy leading to the known misunderstandings between real image and representation. Indeed, the vision of the thing requires a culture and means that the report, so that a text, a picture, a description or photograph will be humanized by the very fact of being informed, as this provides a way a priori. Thus, the landscape provides a function that sets both aspects of a potential landscape as described aspects of the landscape and can only talk about the potential of the final state of the landscape, while the landscape remains humanized by the observer himself. This question forces to choose a definition of remote landscape budgets purely cultural, so there is another way for research to contemplate that physical reality in terms of the coordinates of the man who inhabits gifted content corresponding to that revelation. Far from the positions of the geomorphology, the term "landscape" and involve a certain condition by contemplation of a subject for which the show is humanized in the act. It should also consider, in the light of the above, if it is not true that all landscapes require that humanized condition, because although they are not inhabited they are always occupied by the look that dwells, like a stage without audience produces no consistent effect. From there the coordinates where this work sets the presence of architecture in defining landscape, a premise which seems to come from the beginning given lie, because that same look is already giving the viewer a sense of order and hierarchy to contemplation, qualities that are at the basis of all architectural activity, in fact the very definition of "natural monument" - in itself a contradiction - expresses this conflict, which has a phenomenon of admiration and overlap between culture and nature as concepts faced since its inception. The conclusion on the dilemma proposed in the thesis has not been another to assume that these two realities are the culture and landscape have overlapped since the beginning of man time forming a pair. It has been said before that the process of invasion of the territory by man is significant, and that meaning is the originating autonomous creation that is isolated as an abstract concept of nature, taking them as working material, and establishing a conceptual opposition in reality and punched by the man who comes to oppose representing the closed and unknown to the enigma of the world interpreted. The question of the significance of the man on the land is subsumed in the creation of products that remain and are testimony of their own culture, so that the trace amount that the man leaves the territory contributes most to the qualification landscape as a concept. That brought into any landscape - by the mere fact of being and being well defined - is already cultural, as it is configured by culture products. The words that can be locked in the stones of the monuments or cities are those of the men who worked there, and also of those who inhabited: even more, the sense of the landscape itself and its conservation are determined by the presence of man as the sole interpreter of concepts such as ecology or conservation, something which becomes manifest also in the awful devastation that produce the phenomena of nature. The natural history, like life, are shaped by success and devastation without special preference, the preference is used for feeding on other kinds of concepts. The question of moral values attributed to the natural world is very ancient, and may be the source or the source of the first religions, an issue that joins the unfailing notion of mortality that defines the existence of man against immanence of nature. That nature is endowed intuitively an "innocent" character assuming that innocence is the opposite of wisdom. The other issue is well, since nature does not even have what is defined as "character" because that is something that serves to qualify beings, but not objects. The question does not fall clearly on the side of the definitions or qualities, but from the analysis of the reality that man is building, destroying or damaging to define the territory, interposing his way resources facilities and possible witness as the main manifestation of its essence. Among the artifacts that man produces one of the most persistent and most conspicuously disclosed is architecture as a way of modification of space and territory. The space can be modified in many ways, but in either case is one of the most characteristic traces that man establishes as a physical manifestation of his own discourse being. Architecture has also proven to be one of the most persistent phenomena, even more than their own language that originates in his speech first. The paradigm wrote in the episode described on the Tower of Babel in the Bible shows the question of ambition of men before God - represented precisely in architecture - is assimilated to the discussion about the primary language. The issue is not trivial, since the phenomenon of creation is something that is granted exclusively to the gods, for that reason inhabit the territories to which men can not reach; territories where the hostel located mythologies gods and demons, with large gaps where to place the minor deities, heroes or hybrid beings where the yoke of the gods with human subjects produces relieving sense of mortality. The commentary on Genesis also gives a value to the art, the myth of Prometheus and fire as creator of excellence. In front of promethean progress, divine value is postulated, and the only possible way to alleviate this progress is the confusion of language, because that is what will produce the dispersion and lack of agreement. The issue may also explain such a common passion for the canonical architecture maintained throughout long periods, like a great machine inertia. It seems that the main concepts of architecture based on simple elements like milestone, lintels, straight and curved stairs or ramps, or other qualified and used are granted to the stone, brick, wood or metal as the primary components of the architectural material maintained throughout many millennia are almost unchanged, as is the case with the eating habits that follow a progression through the raw, the cooked and roasted or fried until obtain different degrees of refinement, but always are based on the primal feeling. The discovery of the architecture comes from a management dimensions, and consequently the geometry. But the geometry is abstract thing like the language so that to make architecture that first absorption capacity which then allows the realization of a device is necessary. Reality and its number exhibit a divorce, like things and their names displayed his; numerical analysis is just one way of seeing reality, rigorous and accurate - though partial - only represents the ideal model to which reality is coming to a greater or lesser extent: the mathematical approach makes the universe can condense on numbers, like reality may condense on names, but neither the name nor the number will reflect in all its complexity. The number is only a means of describing things, such as the pure forms that match setup a mathematical theory that occurs anywhere in the universe. However, for the practice of architecture is necessary to go to the simplification that requires abstract view of a section plane of reality, as an abstract element considered cutting. With its trace or not, with the mathematical expression that describes what or without clarify, this intuition of the plane as a generator of space predates his own expression, like speech preceded the writing, which only occurred through it and as reinforcement and replacement of memory. There are abstractions of memory displayed on the signs of nature only on casual and fragmentary, such as line, square and circle: those initials and abstract forms located in abstraction give rise to the first signs of primordial architecture, so that squares and circles, lifting two prisms and spheroids or spherical surfaces appear in tombs and elementary buildings the first few times, and that primordial geometry overlaps the landscape in which it is inserted. It is also true that these forms are approximate objects found in the physical environment, limb lines, branches and limbs; straight in some crystals angles observed by cutting or circular in stars and craters forms, but only the approximate shape and not its abstraction, just as the hieroglyphic of a falcon to represent the idea of surveillance presents the good view, or even the image of the eye itself replace the idea of the all-seeing God. The election was resolved, after many attempts and approaches, with the adoption of the right angle as an easy trick for stake through the sacred triangle 3:4:5 already used to build the pyramids of Egypt, and also gave rise to most of the old urbanism tend coexist with the primary circular form type called "Tholo". That frame homer was one of the fill patterns of common and compact space, and that was probably the reason why in much later times was adopted as a permanent effective form of organization against the topological disorder that seeks the set of association circular plants. Another issue is that these paradigmatic and unknown primary concepts - that converge at the origin of civilizations - then become something canon, through use. The canon itself is something ideal, as a rule for objects of a reality that has been created only as an indication of the ca-non, something abstract that has strict proportions are always the same and not due to rational criteria: be absurd however seek the Greek canon among the temples of time as some did, because the buildings only approximate the canonical examples and for that reason we speak of "doric from Parthenon" which is different from Aegina or Paestum, being all clearly doric. However, this idea is useful to scholar, the architectural theorist and historian, although it reflects only a vague idea of what happens beyond the book. Another issue is the subtlety of the examples of architecture, just as the bodies of living beings are never symmetrical, even if they involve a general symmetrical design derived from the conditions of cell division, the supposedly canonical buildings where specialists were inspired to define the classical orders do not have that exact modular symmetry, but a general model adapted to the ever changing location of the site shaping the landscape in which they are inserted. The light of the various bays of the Parthenon is slightly different, but keep a clear sense of axial symmetry, so that those "orders" that formed the theory of architecture are just a beautiful sectoral interpretation of ancient architecture developed by writers of the Renaissance and later by neoclassical. It seems, however, that craving for clarity of language canon as is inherent to the development of architecture, a lingua franca that tends to avoid scattering among mortals by the ancient gods, so if it was not possible the heaven of the gods sought the language of the Earth was at least intelligible to be understood. Power structure has always required a certain level of organization, and the instructions are clearly understood: it seems that in our times these ancient canons were replaced by obedience to abstract rules, issued by institutions also somewhat abstract and have funny names made up acronym, although not well known virtue. The current canon consists of "rules" that leave some quiet, although it seems that maybe all that interweaves-do formally serving as anaesthesia for the social body also seeks the destruction of forests in forms of huge mountains of bureaucratic paper. For many centuries were other rules, in the form of a canon which no one could escape: still using royalties or without them, civilization flourished in architecture from the earliest cave shelters or shelters and the primordial reality was setting mode in landscape. As noted above, this is a return trip in which both confused and subsumed: the management of forms and languages of architecture over time would allow the distinction between the field where chaos reigns and city, where order reigns theoretically creating a divorce that lasted millennia and still persists. This opposition also generate a form of landscape and a series of symbolic and sacred uses of architectural elements - such as doors and walls - which have remained conceptually although today the cities no longer having physical walls or doors close during the night. In this sense, the architecture could define the landscape, architecture is not only understood as the buildings themselves, but the fact of the manifestation of the man on the premises, so you can not speak without his landscape architecture, the same so we can not speak of landscape without men. For this reason, the thesis discusses architecture and landscape, but more particularly to the fact of architecture in defining landscape, as the facts of architectural or not will determine the quality and qualification of a landscape. One should begin first a definition of what is understood and has been commonly understood by landscape: equally, and given the context in which it places the own thesis work, the issue only be limited to what is understood as western culture, for the development of civilization always has a local colour that makes the analysis of a phenomenon of this magnitude have different connotations in different areas of civilization. Similarly, and given also that the landscape is constructed through all cultural manifestations, will sometimes necessary to investigate other non-architectural disciplines to understand the scope of some cases in which the architectural remains have disappeared, or the remaining few traces. Such a broad definition of architecture take to write a story about all of Western culture and for this reason only been sketched ideas about the appearance of these signs on the landscape based on ancient and primitive elements are repeated insistently and leading the varied repertoire of Western architecture shaping ideas about how the media and the world is perceived and inhabited.

Overexpression of a Homeobox Gene, LeT6, Reveals Indeterminate Features in the Tomato Compound Leaf1

The cultivated tomato (Lycopersicon esculentum) has a unipinnate compound leaf. In the developing leaf primordium, major leaflet initiation is basipetal, and lobe formation and early vascular differentiation are acropetal. We show that engineered alterations in the expression of a tomato homeobox gene, LeT6, can cause dramatic changes in leaf morphology. The morphological states are variable and unstable and the phenotypes produced indicate that the tomato leaf has an inherent level of indeterminacy. This is manifested by the production of multiple orders of compounding in the leaf, by numerous shoot, inflorescence, and floral meristems on leaves, and by the conversion of rachis-petiolule junctions into “axillary” positions where floral buds can arise. Overexpression of a heterologous homeobox transgene, kn1, does not produce such phenotypic variability. This indicates that LeT6 may differ from the heterologous kn1 gene in the effects manifested on overexpression, and that 35S-LeT6 plants may be subject to alterations in expression of both the introduced and endogenous LeT6 genes. The expression patterns of LeT6 argue in favor of a fundamental role for LeT6 in morphogenesis of leaves in tomato and also suggest that variability in homeobox gene expression may account for some of the diversity in leaf form seen in nature.

Interval bias in 2AFC detection tasks: sorting out the artifacts

Proportion correct in two-alternative forcedchoice (2AFC) detection tasks often varies when the stimulus is presented in the first or in the second interval.Reanalysis of published data reveals that these order effects (or interval bias) are strong and prevalent, refuting the standard difference model of signal detection theory. Order effects are commonly regarded as evidence that observers use an off-center criterion under the difference model with bias. We consider an alternative difference model with indecision whereby observers are occasionally undecided and guess with some bias toward one of the response options. Whether or not the data show order effects, the two models fit 2AFC data indistinguishably, but they yield meaningfully different estimates of sensory parameters. Under indeterminacy as to which model governs 2AFC performance, parameter estimates are suspect and potentially misleading. The indeterminacy can be circumvented by modifying the response format so that observers can express indecision when needed. Reanalysis of published data collected in this way lends support to the indecision model. We illustrate alternative approaches to fitting psychometric functions under the indecision model and discuss designs for 2AFC experiments that improve the accuracy of parameter estimates, whether or not order effects are apparent in the data.

Paired structures in knowledge representation.

In this position paper we propose a consistent and unifying view to all those basic knowledge representation models that are based on the existence of two somehow opposite fuzzy concepts. A number of these basic models can be found in fuzzy logic and multi-valued logic literature. Here it is claimed that it is the semantic relationship between two paired concepts what determines the emergence of different types of neutrality, namely indeterminacy, ambivalence and conflict, widely used under different frameworks (possibly under different names). It will be shown the potential relevance of paired structures, generated from two paired concepts together with their associated neutrality, all of them to be modeled as fuzzy sets. In this way, paired structures can be viewed as a standard basic model from which different models arise. This unifying view should therefore allow a deeper analysis of the relationships between several existing knowledge representation formalisms, providing a basis from which more expressive models can be later developed.

Technology Language and Frankenstein Strategy

Teaching architecture is experiencing a moment of opportunity. New methods, like constructivist pedagogy, based on complexity and integration are yet to be explored. In this context of opportunity teaching architecture has a duty to integrate complexity in their curriculum. Teaching methods should also assume inherent indeterminacy and contingency of all complex process. If we accept this condition as part of any teaching method, the notion of truth or falsehood it becomes irrelevant. In this regard it could focus on teaching to contingency of language. Traditionally, technology is defined as the language of science. If we assume contingency as one of the characteristics of language, we could say that technology is also contingent. Therefore we could focus technology teaching to redefine its own vocabulary. So, redefining technological vocabulary could be an area of opportunity for education in architecture. The student could redefine their own tools, technology, to later innovate with them. First redefine the vocabulary, the technology, and then construct the new language, the technique. In the case of Building Technology subjects, it should also incorporate a more holistic approach for enhancing interdisciplinary transfer. Technical transfer, either from nature or other technologies to the field of architecture, is considered as a field of great educational possibilities. Evenmore, student get much broader technical approach that transgresses the boundaries of architectural discipline.

Proximité à distance : les fonctions critiques de la mimêsis dans la pensée de Theodor W. Adorno

La présente thèse entend donner sens à un concept qui occupe une place centrale au sein de la pensée de Theodor W. Adorno mais qui, parce que notoirement difficile à définir, n’a pas reçu l’attention qu’il mérite : la mimêsis (Mimesis). Il s’agira, plus exactement, de comprendre la mimêsis comme un point nodal de la critique adornienne, qui nous permet de comprendre au nom et en vue de quoi elle se déploie. Car sous toutes ses acceptions – et nous verrons qu’elles sont fort variées – la mimêsis adornienne est toujours invoquée dans le but de contrecarrer les tendances hétéronomes (c’est-à-dire : déshumanisantes) propres aux sociétés capitalistes avancées. Surtout, elle est constamment présentée comme un correctif matérialiste au type de rationalité abstraite qui sous-tend ces sociétés. Cette tâche s’avère d’autant plus lourde que, malgré son important poids normatif, la mimêsis ne fait pas l’objet, chez Adorno, d’une théorisation explicite. Il nous faudra pallier cette indétermination, en identifiant d’abord les assises normatives les plus premières de la critique adornienne (0.0. Introduction : les fondements normatifs de la critique adornienne), pour ensuite rendre compte des fonctions particulières qu’occupe la mimêsis au sein de cette critique (1.0. Les fonctions critiques de la mimêsis adornienne). Ce travail de débroussaillage exégétique et interprétatif nous permettra de constater que la mimêsis adornienne recèle trois types de potentiels critiques distincts. D’abord, en ce qu’elle est présentée – dans les travaux des années 1930 et 1940 surtout – comme une impulsion psychosomatique à même de trahir, l’instant d’une brève résistance, la violence infligée à la nature intérieure et extérieure de l’homme par les forces réificatrices de la rationalité instrumentale (Instrumentelle Vernunft), la mimêsis adornienne peut être comprise comme un mimétisme (Mimikry) bioanthropologique dont la valeur est principalement expressive (2.O. Mimikry : le potentiel bioanthropologique de la mimêsis). Ensuite, lorsqu’elle sera pensée – à partir de la fin des années 50 surtout – comme une compétence proprement épistémique qui permet au sujet connaissant de rencontrer à nouveau puis de redéterminer les objets de son expérience, la mimêsis adornienne peut être comprise comme un correctif critique à la logique appropriative de la pensée identifiante (identifizierendes Denken) (3.O. Affinität et Entäusserung : le potentiel épistémique de la mimêsis). Enfin, dans la mesure où elle informe le modus operandi de l’oeuvre d’art d’avant-garde telle que défendue par Adorno dans la Théorie esthétique, et qui consiste à détourner, en les retournant contre elles-mêmes, les contraintes imposées par le monde totalement administré (total verwaltete Welt), la mimêsis peut être comprise comme une Methexis subversive, c’est-à-dire comme une stratégie séditieuse à même de conjurer l’hétéronomie sociale en l’anticipant et en l’incorporant (4.0. Methexis subversive : le potentiel stratégique de la mimêsis). Ainsi, tout en voulant rendre justice à la très grande polysémie du concept, nous aimerions démontrer que la mimêsis adornienne pointe constamment vers une forme ou une autre de résistance : comme expression, comme extériorisation ou comme subversion.

Blocking the path from vagueness to four dimensionalism

There is a general form of an argument which I call the 'argument from vagueness' which attempts to show that objects persist by perduring, via the claim that vagueness is never ontological in nature and thus that composition is unrestricted. I argue that even if we grant that vagueness is always the result of semantic indeterminacy rather than ontological vagueness, and thus also grant that composition is unrestricted, it does not follow that objects persist by perduring. Unrestricted mereological composition lacks the power to ensure that there exist instantaneous objects that wholly overlap persisting objects at times, and thus lacks the power to ensure that there exists anything that could be called a temporal part. Even if we grant that such instantaneous objects exist, however, I argue that it does not follow that objects perdure. To show this I briefly outline a coherent version of three dimensionalism that grants just such an assumption. Thus considerations pertaining to the nature of vagueness need not lead us inevitably to accept perdurantism.

Non-mereological universalism

In this paper I develop a version of universalism that is non-mereological. Broadly speaking, non-mereological universalism is the thesis that for any arbitrary set of objects and times, there is a persisting object which, at each of those times, will be constituted by those of the objects that exist at that time. I consider two general versions of non-mereological universalism, one which takes basic simples to be enduring objects, and the other which takes simples to be instantaneous objects. This yields three versions of endurantism, of which I ultimately defend the version I call universalist endurantism. Universalist endurantism is the thesis that (i) for any arbitrary set S of instantaneous simples that exist at the same instant, there exists a fusion of the members of S, and (ii) for any arbitrary set S* of instantaneous fusions each of which exist at a different instant, there exists an enduring object O that is constituted by those fusions at those instants. Universalist endurantism is ‘non-mereological’ in that the relation that holds between instantaneous fusions and persisting objects is not the part/whole relation, but rather, is the relation of constitution, thus allowing that the persisting objects are three rather than four dimensional. I argue that universalist endurantism not only has the various benefits of mereological universalism in allowing vagueness to be explicated as semantic indeterminacy, but in addition allows the endurantist to hold that some properties are genuinely intrinsic and are exemplified simpliciter.

The discourse of biology lectures : aspects of its mode and text structure

The present thesis investigates mode related aspects in biology lecture discourse and attempts to identify the position of this variety along the spontaneous spoken versus planned written language continuum. Nine lectures (of 43,000 words) consisting of three sets of three lectures each, given by the three lecturers at Aston University, make up the corpus. The indeterminacy of the results obtained from the investigation of grammatical complexity as measured in subordination motivates the need to take the analysis beyond sentence level to the study of mode related aspects in the use of sentence-initial connectives, sub-topic shifting and paraphrase. It is found that biology lecture discourse combines features typical of speech and writing at sentence as well as discourse level: thus, subordination is more used than co-ordination, but one degree complexity sentence is favoured; some sentence initial connectives are only found in uses typical of spoken language but sub-topic shift signalling (generally introduced by a connective) typical of planned written language is a major feature of the lectures; syntactic and lexical revision and repetition, interrupted structures are found in the sub-topic shift signalling utterance and paraphrase, but the text is also amenable to analysis into sentence like units. On the other hand, it is also found that: (1) while there are some differences in the use of a given feature, inter-speaker variation is on the whole not significant; (2) mode related aspects are often motivated by the didactic function of the variety; and (3) the structuring of the text follows a sequencing whose boundaries are marked by sub-topic shifting and the summary paraphrase. This study enables us to draw four theoretical conclusions: (1) mode related aspects cannot be approached as a simple dichotomy since a combination of aspects of both speech and writing are found in a given feature. It is necessary to go to the level of textual features to identify mode related aspects; (2) homogeneity is dominant in this sample of lectures which suggests that there is a high level of standardization in this variety; (3) the didactic function of the variety is manifested in some mode related aspects; (4) the features studied play a role in the structuring of the text.
