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.

SOA-Based Model for Value-Added ITS Services Delivery

Integration is currently a key factor in intelligent transportation systems (ITS), especially because of the ever increasing service demands originating from the ITS industry and ITS users. The current ITS landscape is made up of multiple technologies that are tightly coupled, and its interoperability is extremely low, which limits ITS services generation. Given this fact, novel information technologies (IT) based on the service-oriented architecture (SOA) paradigm have begun to introduce new ways to address this problem. The SOA paradigm allows the construction of loosely coupled distributed systems that can help to integrate the heterogeneous systems that are part of ITS. In this paper, we focus on developing an SOA-based model for integrating information technologies (IT) into ITS to achieve ITS service delivery. To develop our model, the ITS technologies and services involved were identified, catalogued, and decoupled. In doing so, we applied our SOA-based model to integrate all of the ITS technologies and services, ranging from the lowest-level technical components, such as roadside unit as a service (RS S), to the most abstract ITS services that will be offered to ITS users (value-added services). To validate our model, a functionality case study that included all of the components of our model was designed.

The concept of 'economic activity' in the EU treaty: from ideological dead-ends to workable judicial concepts. Research Paper in Law 06/2011

[From the Introduction]. The economic rules, or put more ambitiously, the economic constitution of the Treaty,1 only apply to economic activities. This general principle remains valid, even if some authors strive to demonstrate that certain Treaty rules also apply in the absence of an economic activity,2 and despite the fact that non-economic (horizontal) Treaty provisions (e.g. principle of nondiscrimination, rules on citizenship) are also applicable in the absence of any economic activity.3 Indeed, the exercise of some economic activity transcends the concepts of ‘goods’ (having positive or negative market value),4 workers (even if admitted in an extensive manner),5 and services (offered for remuneration).6 It is also economic activity or ‘the activity of offering goods and services into the market’7 that characterises an ‘undertaking’ thus making the competition rules applicable. Further, it is for regulating economic activity that Article 115 TFEU, Article 106(3) TFEU and most other legal bases in the TFEU provide harmonisation powers in favour of the EU. Last but not least, Article 14 TFEU on the distinction between services of general economic interest (SGEIs) and non-economic services of general interest (NESGIs), as well as Protocol n. 26 on Services of General Interest (SGIs) confirm the constitutional significance of the distinction between economic and non-economic: a means of dividing competences between the EU and the member states. The distinction between economic and non-economic activities is fraught with legal and technical intricacies – the latter being generated by dynamic technological advances and regulatory experimentation. More importantly, however, the distinction is overcharged with political and ideological significations and misunderstandings and, even, terminological confusions.8

A prova ilícita na investigação de paternidade

A presente dissertação versa sobre a prova ilícita na investigação de paternidade, com a percepção que inexistem direitos e garantias absolutos. Sob esse ponto de vista, propõe-se a demonstrar que tanto o direito à prova quanto a garantia constitucional da inadmissibilidade da prova obtida por meios ilícitos são passíveis de sofrer restrições. Essas restrições, entretanto, não podem implicar na supressão de direitos e garantias fundamentais. Elas devem limitar-se ao estritamente necessário para a salvaguarda de outros direitos constitucionalmente protegidos, à luz de um juízo de ponderação entre os valores conflitantes. Os valores colidentes a serem analisados no presente trabalho são, por um lado, a proteção constitucional dispensada à intimidade, à vida privada, à imagem, à honra, ao sigilo da correspondência, às comunicações telegráficas, aos dados, às comunicações telefônicas e ao domicílio do suposto pai e, por outro, o direito do filho conhecer a sua origem genética e receber do genitor assistência material, educacional e psicológica, além da herança no caso de morte deste. Avultam-se, ainda, os comandos constitucionais da paternidade responsável (CF, o art. 226, § 7º) e da prioridade absoluta que a Constituição Federal confere às questões afetas à criança e ao adolescente. Nessa linha de perspectiva, procura conciliar o direito fundamental ao conhecimento da origem genética com a garantia constitucional que veda a obtenção da prova por meios ilícitos, reduzindo, quando necessário, o alcance de um desses valores contrastantes para que haja a preservação do outro e o restabelecimento do equilíbrio entre eles. Com o intuito de facilitar a compreensão do assunto, o estudo sobre a prova ilícita na investigação de paternidade encontra-se dividido em três capítulos. No primeiro capítulo são estudados o objeto da prova na investigação de paternidade, os fatos a provar, as teorias sobre o objeto da prova, o ônus da prova, a distribuição e a inversão do ônus da prova na investigação de paternidade, o momento da inversão do ônus da prova, o dever de colaboração e a realização do exame de DNA sem o consentimento das partes. Partindo da compreensão da prova como instrumento capaz de propiciar ao juiz o convencimento dos fatos pertinentes, relevantes e controvertidos deduzidos pelas partes como fundamento da ação ou da defesa, sustenta-se que os fatos a provar não são apenas os principais, mas, também, os acessórios que se situem na mesma cadeia deles. Desenvolve-se, outrossim, estudo sobre as teorias utilizadas pela doutrina para explicar o objeto da prova, a saber: a) a teoria clássica; b) a teoria da afirmação; c) a teoria mista. Nesse tópico, merece ênfase o fato das legislações brasileira e portuguesa estarem alicerçadas sob as bases da teoria clássica, em que pesem as divergências doutrinárias sobre o assunto. No item reservado ao ônus da prova, este é concebido como uma atividade e não como uma obrigação, diante da autonomia de vontade que a parte tem para comportar-se da maneira que melhor lhe aprouver para alcançar o resultado pretendido. Embora não traduza um dever jurídico demonstrar a veracidade dos fatos que ensejam a constituição do direito alegado, quem não consegue reunir a prova dos fatos que alega corre o risco de perder a demanda. No que tange à regra de distribuição do ônus da prova, recomenda-se a observação das disposições do art. 333 do CPC, segundo as quais incumbe ao autor comprovar o fato constitutivo do seu direito e ao réu a existência de fato impeditivo, modificativo ou extintivo do direito do autor. Argumenta-se que o CPC brasileiro adota o modelo estático de distribuição do ônus da prova, pois não leva em conta a menor ou maior dificuldade que cada parte tem para produzir a prova que lhe incumbe. Porém, ressalta-se o novo horizonte que se descortina no anteprojeto do novo CPC brasileiro que se encontra no Congresso Nacional, o qual sinaliza no sentido de acolher a distribuição dinâmica do ônus da prova. Esse novo modelo, contudo, não afasta aquele previsto no art. 333 do CPC, mas, sim, o aperfeiçoa ao atribuir o ônus a quem esteja em melhores condições de produzir a prova. Ao tratar do dever de colaboração, idealiza-se a busca descoberta da verdade como finalidade precípua do ordenamento jurídico. E, para se alcançar a justa composição da lide, compreende-se que as partes devem atuar de maneira escorreita, expondo os fatos conforme a verdade e cumprindo com exatidão os provimentos formais. Sob essa ótica, sustenta-se a possibilidade de inversão do ônus da prova, da aplicação da presunção legal de paternidade e até mesmo da condução coercitiva do suposto pai para a realização de exames, caso o mesmo a tanto se recuse ou crie, propositalmente, obstáculo capaz de tornar impossível a colheita da prova. Defende-se que a partir da concepção do nascituro, a autonomia de vontade dos pais fica restringida, de forma que a mãe não pode realizar o aborto e o pai não pode fazer pouco caso da existência do filho, recusando-se, injustificadamente, a submeter-se a exame de DNA e a dar-lhe assistência material, educacional e psicológica. É por essa razão que, em caráter excepcional, se enxerga a possibilidade de condução coercitiva do suposto pai para a coleta de material genético, a exemplo do que ocorre no ordenamento jurídico alemão (ZPO, § 372). Considera-se, outrossim, que a elucidação da paternidade, além de ajudar no diagnóstico, prevenção e tratamento de algumas doenças hereditárias, atende à exigência legal de impedir uniões incestuosas, constituídas entre parentes afins ou consanguíneos com a violação de impedimentos matrimoniais. Nesse contexto, a intangibilidade do corpo não é vista como óbice para a realização do exame de DNA, o qual pode ser feito mediante simples utilização de fios de cabelos com raiz, fragmentos de unhas, saliva e outros meios menos invasivos. O sacrifício a que se submete o suposto pai mostra-se, portanto, ínfimo se comparado com o interesse superior do investigante que se busca amparar. No segundo capítulo, estuda-se o direito fundamental à prova e suas limitações na investigação de paternidade, a prova vedada ou proibida, a distinção entre as provas ilegítima e ilícita, a manifestação e alcance da ilicitude, o tratamento dispensado à prova ilícita no Brasil, nos Estados Unidos da América e em alguns países do continente europeu, o efeito-à-distância das proibições de prova na investigação de paternidade e a ponderação de valores entre os interesses em conflito: prova ilícita x direito ao conhecimento da origem genética. Nesse contexto, o direito à prova é reconhecido como expressão do princípio geral de acesso ao Poder Judiciário e componente do devido processo legal, materializado por meio dos direitos de ação, de defesa e do contraditório. Compreende-se, entretanto, que o direito à prova não pode ser exercido a qualquer custo. Ele deve atender aos critérios de pertinência, relevância e idoneidade, podendo sofrer limitações nos casos expressamente previstos em lei. Constituem exemplos dessas restrições ao direito à prova a rejeição das provas consideradas supérfluas, irrelevantes, ilegítimas e ilícitas. A expressão “provas vedadas ou proibidas” é definida no trabalho como gênero das denominadas provas ilícita e ilegítima, servindo para designar as provas constituídas, obtidas, utilizadas ou valoradas com afronta a normas de direito material ou processual. A distinção que se faz entre a prova ilícita e a ilegítima leva em consideração a natureza da norma violada. Quando há violação a normas de caráter processual, sem afetar o núcleo essencial dos direitos fundamentais, considera-se a prova ilegítima; ao passo em que havendo infringência à norma de conteúdo material que afete o núcleo essencial do direito fundamental, a prova é tida como ilícita. Esta enseja o desentranhamento da prova dos autos, enquanto aquela demanda a declaração de nulidade do ato sem a observância da formalidade exigida. A vedação da prova ilícita, sob esse aspecto, funciona como garantia constitucional em favor do cidadão e contra arbítrios do poder público e dos particulares. Nessa ótica, o Direito brasileiro não apenas veda a prova obtida por meios ilícitos (CF, art. 5º, X, XI, XII e LVI; CPP, art. 157), como, também, prevê sanções penais e civis para aqueles que desobedeçam à proibição. A análise da prova ilícita é feita à luz de duas concepções doutrinárias, a saber: a) a restritiva - exige que a norma violada infrinja direito ou garantia fundamental; b) a ampla – compreende que a ilicitude afeta não apenas as normas que versem sobre os direitos e garantias fundamentais, mas todas as normas e princípios gerais do direito. A percepção que se tem à luz do art. 157 do CPP é que o ordenamento jurídico brasileiro adotou o conceito amplo de ilicitude, pois define como ilícitas as provas obtidas com violação a normas constitucionais ou legais, sem excluir àquelas de natureza processual nem exigir que o núcleo do direito fundamental seja atingido. Referido dispositivo tem sido alvo de críticas, pois a violação da lei processual pode não implicar na inadmissibilidade da prova e aconselhar o seu desentranhamento dos autos. A declaração de nulidade ou renovação do ato cuja formalidade tenha sido preterida pode ser suficiente para contornar o problema, sem a necessidade de exclusão da prova do processo. Noutra vertente, como a vedação da prova ilícita não pode ser levada às últimas consequências nem se converter em meio facilitador da prática de atos ilícitos e consagrador da impunidade, defende-se a sua admissão nos casos de estado de necessidade, legítima defesa, estrito cumprimento do dever legal e exercício regular de um direito. Assim, entende-se possível a utilização pela vítima de estupro, no processo de investigação de paternidade movido em prol do seu filho, do exame de DNA realizado mediante análise do sêmen deixado em sua vagina por ocasião do ato sexual que resultou na gravidez. Sustenta-se, ainda, a possibilidade de utilização das imagens captadas por circuito interno de câmaras comprobatórias do estupro para fazer prova da paternidade. Ressalta-se, outrossim, que no Brasil a doutrina e a jurisprudência têm admitido a prova ilícita, no processo penal, para comprovar a inocência do acusado e, em favor da vítima, nos casos de extorsão, concussão, sequestro e outros delitos similares. No ponto relativo ao efeito-àdistância das proibições de prova, aduz-se que as experiências americana e alemã da fruit of the poisonous tree doctrine e da fernwirkung são fonte de inspiração para as legislações de vários países. Por força da teoria dos frutos da árvore envenenada, o vício da planta transmite-se aos seus frutos. Ainda no segundo capítulo, estabelece-se breve comparação do tratamento conferido à prova ilícita nos ordenamentos jurídicos brasileiro e português, destacando-se que no regime de controle adotado pela Constituição da República Federativa do Brasil a prova ilícita é tratada como ineficaz e deve ser rejeitada de plano ou desentranhada do processo. Já na Constituição portuguesa adotou-se o regime de nulidade. Após o ingresso da prova ilícita no processo, o juiz declara a sua nulidade. O terceiro capítulo é dedicado ao estudo dos meios de prova e da incidência da ilicitude no processo de investigação de paternidade. Para tanto são eleitos os meios de prova enumerados no art. 212 do Código Civil, quais sejam: a) confissão; b) documento; c) testemunha; d) presunção; e) perícia, além do depoimento pessoal previsto no CPC, analisando a incidência da ilicitude em cada um deles. Má vontade a investigação de paternidade envolva direitos indisponíveis, isso não significa que as declarações das partes não tenham valor probatório, pois o juiz pode apreciá-las como elemento probatório (CC, art. 361º). Por meio do depoimento e confissão da parte são extraídas valiosas informações sobre o tempo, o lugar e a frequência das relações sexuais. Todavia, havendo emprego de métodos proibidos, tais como ameaça, coação, tortura, ofensa à integridade física ou moral, hipnose, utilização de meios cruéis, enganosos ou perturbação da capacidade de memória, a prova será considerada ilícita e não terá validade nem mesmo como elemento probatório a ser livremente apreciado pelo juiz. A prova documental é estudada como a mais vulnerável à incidência da ilicitude, pelo fato de poder expressar-se das mais variadas formas. Essa manifestação da ilicitude pode verificar-se por ocasião da formação da prova documental, no ato da sua obtenção ou no momento da sua exibição em juízo por meio falsificação material do documento público ou particular, da omissão de declaração deveria constar, inserção de declaração falsa ou diversa da que devia ser escrita, alteração de documento verdadeiro, emprego de métodos proibidos de prova para confecção do documento, etc. Na esteira desse raciocínio, em se fazendo constar, por exemplo, da escritura pública ou particular ou do testamento (CC, art. 1.609, II e III) declaração falsa da paternidade, a prova assim constituída é ilícita. Do mesmo modo, é considerada ilícita a prova obtida mediante indevida intromissão na vida privada, com violação de domicílio, emails, sigilos da correspondência, telefônico ou fiscal, realização de gravações, filmagens, etc. Na prova testemunhal entende-se como elemento configurador da ilicitude o emprego de métodos proibidos por parte de agentes públicos ou particulares, tais como tortura, coação, ameaça, chantagem, recursos que impliquem na diminuição ou supressão da capacidade de compreensão, etc, para que a testemunha faça afirmação falsa, negue ou cale a verdade dos fatos. Destaca-se, ainda, como ilícita a prova cujo acesso pela testemunha tenha ocorrido mediante violação à reserva da vida privada. No caso das presunções, vislumbra-se a possibilidade de incidência da ilicitude quando houver ilicitude no fato conhecido, do qual se vale a lei ou o julgador para extraírem as consequências para dedução da existência do fato desconhecido. A troca maliciosa de gametas é citada como meio ilícito de prova para alicerçar a presunção de paternidade no caso de inseminação artificial homóloga. A consecução da prévia autorização do marido, mediante coação, tortura, ameaça, hipnose, etc, na inseminação artificial heteróloga, também é tratada como ação danosa e capaz de viciar e infirmar a presunção legal de paternidade. Enxerga-se, outrossim, no meio de prova pericial, a possibilidade de maculação do resultado do exame por falha humana intencional no processo de coleta, transporte, armazenamento, manipulação ou troca do material genético coletado. Em se verificando essa situação, fica comprometida a credibilidade da prova pericial ante a sua ilicitude.

An interpretive approach to analysing the role and value of information systems in Jordanian financial organisations

Analysing investments in ISs in order to maximise benefits has become a prime concern, especially for private corporations. No formula of equilibrium exists that could link the injected amounts and accrued returns. The relationship is simply not straightforward. This thesis is based upon empirical work which involved sketching organisational ethnographies (four organographies and a sectography) into the role and value of information systems in Jordanian financial organisations. Besides deciphering the map of impacts, it explains the attributions of the variations in the impacts of ISs which were found to be related to the internal organisational processes: culturally and politically specific considerations, economically or technically rooted factors and environmental factors. The research serves as an empirical attempt to test out the applicability of adopting the interpretive paradigm to researching organisations in a developing country. The fieldwork comprised an exploratory stage, a detailed investigation of four case studies and a survey stage encompassing 16 organisations. Primary and secondary data were collected from multiple sources using a range of instruments. The evidence highlights the fact that little long term strategic planning was pursued; the emphasis was more focused on short term planning. There was no noticeable adoption of any strategic fit principle linking IS strategy to the corporate strategy. In addition, the benefits obtained were mostly intangible. Although ISs were central to the work of the organisations surveyed as the core technology, they were considered as tools or work enablers rather than weapons for competitive rivalry. The cultural specificity of IS impacts was evident and the cultural and political considerations were key factors in explaining the attributions of the variations in the impacts of ISs in JFOs. The thesis confirms that measuring the benefits of ISs is the problematic. However, in order to gain more insight, the phenomenon of "the use of ISs" has to be studied within its context.

Az egyensúlyi ráták unicitása és a bérráta pozitivitása a Neumann-modell általánosításaiban (Uniqueness of equilibrium rates and the positive value of the wage rate in generalizations from the Neumann model)

Cikkünk arról a paradox jelenségről szól, hogy a fogyasztást explicit módon megjelenítő Neumann-modell egyensúlyi megoldásaiban a munkabért meghatározó létszükségleti termékek ára esetenként nulla lehet, és emiatt a reálbér egyensúlyi értéke is nulla lesz. Ez a jelenség mindig bekövetkezik az olyan dekomponálható gazdaságok esetén, amelyekben eltérő növekedési és profitrátájú, alternatív egyensúlyi megoldások léteznek. A jelenség sokkal áttekinthetőbb formában tárgyalható a modell Leontief-eljárásra épülő egyszerűbb változatában is, amit ki is használunk. Megmutatjuk, hogy a legnagyobbnál alacsonyabb szintű növekedési tényezőjű megoldások közgazdasági szempontból értelmetlenek, és így érdektelenek. Ezzel voltaképpen egyrészt azt mutatjuk meg, hogy Neumann kiváló intuíciója jól működött, amikor ragaszkodott modellje egyértelmű megoldásához, másrészt pedig azt is, hogy ehhez nincs szükség a gazdaság dekomponálhatóságának feltételezésére. A vizsgált téma szorosan kapcsolódik az általános profitráta meghatározásának - Sraffa által modern formába öntött - Ricardo-féle elemzéséhez, illetve a neoklasszikus növekedéselmélet nevezetes bér-profit, illetve felhalmozás-fogyasztás átváltási határgörbéihez, ami jelzi a téma elméleti és elmélettörténeti érdekességét is. / === / In the Marx-Neumann version of the Neumann model introduced by Morishima, the use of commodities is split between production and consumption, and wages are determined as the cost of necessary consumption. In such a version it may occur that the equilibrium prices of all goods necessary for consumption are zero, so that the equilibrium wage rate becomes zero too. In fact such a paradoxical case will always arise when the economy is decomposable and the equilibrium not unique in terms of growth and interest rate. It can be shown that a zero equilibrium wage rate will appear in all equilibrium solutions where growth and interest rate are less than maximal. This is another proof of Neumann's genius and intuition, for he arrived at the uniqueness of equilibrium via an assumption that implied that the economy was indecomposable, a condition relaxed later by Kemeny, Morgenstern and Thompson. This situation occurs also in similar models based on Leontief technology and such versions of the Marx-Neumann model make the roots of the problem more apparent. Analysis of them also yields an interesting corollary to Ricardo's corn rate of profit: the real cause of the awkwardness is bad specification of the model: luxury commodities are introduced without there being a final demand for them, and production of them becomes a waste of resources. Bad model specification shows up as a consumption coefficient incompatible with the given technology in the more general model with joint production and technological choice. For the paradoxical situation implies the level of consumption could be raised and/or the intensity of labour diminished without lowering the equilibrium rate of the growth and interest. This entails wasteful use of resources and indicates again that the equilibrium conditions are improperly specified. It is shown that the conditions for equilibrium can and should be redefined for the Marx-Neumann model without assuming an indecomposable economy, in a way that ensures the existence of an equilibrium unique in terms of the growth and interest rate coupled with a positive value for the wage rate, so confirming Neumann's intuition. The proposed solution relates closely to findings of Bromek in a paper correcting Morishima's generalization of wage/profit and consumption/investment frontiers.

Public-Private Partnership Design for Inclusive Cocoa Global Value Chains in Ghana

Within 10 years, there could be a severe global shortage in the supply of cocoa, according to industry practitioners and other experts. Due to global population growth and the emergence of a growing global middle class, by 2025 the cocoa crop would need to increase by nearly 50 per cent to keep up with projected demand. A potential shortage of supply is a direct threat to the business model of lead firms – including cocoa grinders and processors, chocolate confectioners, and retail distributors. But these international firms – the ones that will suffer the most if there is a shortage of cocoa supply – are helping create the market failure that is stifling sustainability. Functioning as a two-tiered consolidated oligopoly with a combined market share of approximately 89%, these firms enjoy the largest portion of value capture in the cocoa-chocolate global value chain (GVC). The smallholder cocoa producers, conversely, are trapped in low value-add segments of the GVC. In fact, most smallholder farmers survive on less than $1.00 per day per capita, on average in many cocoa exporting countries. In Ghana - the second largest producer of cocoa in the world - the government has accomplished little to help these smallholders upgrade and make cocoa an attractive sector for the next generation to inherit. The result – both in Ghana and around the world – is a lack of sustainability of the supply of cocoa. Demand is already beginning to outstrip supply. As a result of these underlying circumstances, the United States Agency for International Development (USAID) has posed the following policy question: "Under what conditions could USAID, as a development agency, support and enhance potential public-private partnerships in order to improve the bargaining power (and financial wherewithal) of smallholder organizations and farmers in the context of the global value chain for cocoa in Ghana?"

The quality of financial information in the extractive industries: a value relevance analysis

The extractive industry is characterized by high levels of risk and uncertainty. These attributes create challenges when applying traditional accounting concepts (such as the revenue recognition and matching concepts) to the preparation of financial statements in the industry. The International Accounting Standards Board (2010) states that the objective of general purpose financial statements is to provide useful financial information to assist the capital allocation decisions of existing and potential providers of capital. The usefulness of information is defined as being relevant and faithfully represented so as to best aid in the investment decisions of capital providers. Value relevance research utilizes adaptations of the Ohlson (1995) to assess the attribute of value relevance which is one part of the attributes resulting in useful information. This study firstly examines the value relevance of the financial information disclosed in the financial reports of extractive firms. The findings reveal that the value relevance of information disclosed in the financial reports depends on the circumstances of the firm including sector, size and profitability. Traditional accounting concepts such as the matching concept can be ineffective when applied to small firms who are primarily engaged in nonproduction activities that involve significant levels of uncertainty such as exploration activities or the development of sites. Standard setting bodies such as the International Accounting Standards Board and the Financial Accounting Standards Board have addressed the financial reporting challenges in the extractive industry by allowing a significant amount of accounting flexibility in industryspecific accounting standards, particularly in relation to the accounting treatment of exploration and evaluation expenditure. Therefore, secondly this study examines whether the choice of exploration accounting policy has an effect on the value relevance of information disclosed in the financial reports. The findings show that, in general, the Successful Efforts method produces value relevant information in the financial reports of profitable extractive firms. However, specifically in the oil & gas sector, the Full Cost method produces value relevant asset disclosures if the firm is lossmaking. This indicates that investors in production and non-production orientated firms have different information needs and these needs cannot be simultaneously fulfilled by a single accounting policy. In the mining sector, a preference by large profitable mining companies towards a more conservative policy than either the Full Cost or Successful Efforts methods does not result in more value relevant information being disclosed in the financial reports. This finding supports the fact that the qualitative characteristic of prudence is a form of bias which has a downward effect on asset values. The third aspect of this study is an examination of the effect of corporate governance on the value relevance of disclosures made in the financial reports of extractive firms. The findings show that the key factor influencing the value relevance of financial information is the ability of the directors to select accounting policies which reflect the economic substance of the particular circumstances facing the firms in an effective way. Corporate governance is found to have an effect on value relevance, particularly in the oil & gas sector. However, there is no significant difference between the exploration accounting policy choices made by directors of firms with good systems of corporate governance and those with weak systems of corporate governance.

Teoria do valor e trabalho produtivo no setor de serviços

Interpretações da teoria do valor trabalho encontram dificuldades em definir o papel e o lugar das atividades de serviço com relação à produção ou não de valor. Esse problema ganha magnitude na medida em que a perspectiva histórica mostra que os serviços são grandes empregadores de mão de obra na atualidade. Tradicionalmente, os serviços são entendidos como atividades não produtivas, devido ao fato, dentre outros argumentos, de que não resultam em materialização na forma de mercadorias, ou que não produzem novos valores e mais-valia. O objetivo deste artigo é examinar essa questão e sugerir a proposição de que certos serviços, que preenchem determinadas condições, podem ser interpretados como produtivos de valor e de mais-valia. O artigo examina as categorias materialidade e imaterialidade, assim como as de trabalho produtivo e não produtivo de valor, introduzindo, a seguir, critérios para distinguir trabalhos produtivos e não produtivos de valor no setor de serviços. Com isso, pretende contribuir para clarificar o entendimento da teoria do valor trabalho num terreno entrecruzado de polêmicas e de posições teóricas diferenciadas. _____________________________________________________________________________________________ ABSTRACT

Determinants of Terminal Value in the Evaluation of Companies: A Panel Data Approach to the Context of European Companies.

The uncertainty of the future of a firm has to be modelled and incorporated into the evaluation of companies outside their explicit period of analysis, i.e., in the continuing or terminal value considered within valuation models. However, there is a multiplicity of factors that influence the continuing value of businesses which are not currently being considered within valuation models. In fact, ignoring these factors may cause significant errors of judgment, which can lead models to values of goodwill or badwill, far from the substantial value of the inherent assets. Consequently, these results provided will be markedly different from market values. So, why not consider alternative models incorporating life expectancy of companies, as well as the influence of other attributes of the company in order to get a smoother adjustment between market price and valuation methods? This study aims to provide a contribution towards this area, having as its main objective the analysis of potential determinants of firm value in the long term. Using a sample of 714 listed companies, belonging to 15 European countries, and a panel data for the period between 1992 and 2011, our results show that continuing value cannot be regarded as the current value of a constant or growth perpetuity of a particular attribute of the company, but instead be according to a set of attributes such as free cash flow, net income, the average life expectancy of the company, investment in R&D, capabilities and quality of management, liquidity and financing structure.

The influence of British rule on elite Indian menswear: the birth of the Sherwani

‘The Influence of British Rule on Elite Indian Menswear: The Birth of the Sherwani’ is a study of the influence of politics on fashion and the resulting development of new garments. This research is designed to demonstrate the effect on elite Indian menswear of the two centuries of British rule in India. It is an effort to understand how the flowing garments worn by elite Indian men in the 18th century gradually became more tailored and fitted with the passage of time. The study uses multiple sources to bring to light lesser known facts about Indian menswear, the evolution of different garments and especially of the sherwani. The sherwani is a knee-length upper garment worn by South-Asian men, and is considered to be India’s traditional menswear. My study highlights the factors responsible for the birth of the sherwani and dispels the myth that it was a garment worn by the Mughals. Simultaneously, this study examines the concept and value of ‘tradition’ in cultures. It scrutinises the reasons for the sherwani being labelled as a traditional Indian garment associated with the Mughal era, when in fact it was born towards the end of the 19th century. The study also analyses the role of the sherwani as a garment of distinction in pre- and post-independence India.

The Value Of The 2005 International Society Of Urological Pathology (isup) Modified Gleason Grading System As A Predictor Of Biochemical Recurrence After Radical Prostatectomy.

To compare time and risk to biochemical recurrence (BR) after radical prostatectomy of two chronologically different groups of patients using the standard and the modified Gleason system (MGS). Cohort 1 comprised biopsies of 197 patients graded according to the standard Gleason system (SGS) in the period 1997/2004, and cohort 2, 176 biopsies graded according to the modified system in the period 2005/2011. Time to BR was analyzed with the Kaplan-Meier product-limit analysis and prediction of shorter time to recurrence using univariate and multivariate Cox proportional hazards model. Patients in cohort 2 reflected time-related changes: striking increase in clinical stage T1c, systematic use of extended biopsies, and lower percentage of total length of cancer in millimeter in all cores. The MGS used in cohort 2 showed fewer biopsies with Gleason score ≤ 6 and more biopsies of the intermediate Gleason score 7. Time to BR using the Kaplan-Meier curves showed statistical significance using the MGS in cohort 2, but not the SGS in cohort 1. Only the MGS predicted shorter time to BR on univariate analysis and on multivariate analysis was an independent predictor. The results favor that the 2005 International Society of Urological Pathology modified system is a refinement of the Gleason grading and valuable for contemporary clinical practice.

Prognostic Value Of Dna And Mrna E6/e7 Of Human Papillomavirus In The Evolution Of Cervical Intraepithelial Neoplasia Grade 2.

This study aimed at evaluating whether human papillomavirus (HPV) groups and E6/E7 mRNA of HPV 16, 18, 31, 33, and 45 are prognostic of cervical intraepithelial neoplasia (CIN) 2 outcome in women with a cervical smear showing a low-grade squamous intraepithelial lesion (LSIL). This cohort study included women with biopsy-confirmed CIN 2 who were followed up for 12 months, with cervical smear and colposcopy performed every three months. Women with a negative or low-risk HPV status showed 100% CIN 2 regression. The CIN 2 regression rates at the 12-month follow-up were 69.4% for women with alpha-9 HPV versus 91.7% for other HPV species or HPV-negative status (P < 0.05). For women with HPV 16, the CIN 2 regression rate at the 12-month follow-up was 61.4% versus 89.5% for other HPV types or HPV-negative status (P < 0.05). The CIN 2 regression rate was 68.3% for women who tested positive for HPV E6/E7 mRNA versus 82.0% for the negative results, but this difference was not statistically significant. The expectant management for women with biopsy-confirmed CIN 2 and previous cytological tests showing LSIL exhibited a very high rate of spontaneous regression. HPV 16 is associated with a higher CIN 2 progression rate than other HPV infections. HPV E6/E7 mRNA is not a prognostic marker of the CIN 2 clinical outcome, although this analysis cannot be considered conclusive. Given the small sample size, this study could be considered a pilot for future larger studies on the role of predictive markers of CIN 2 evolution.
