La filosofia di Hans-Georg Gadamer e il problema del disagio della modernità. Ermeneutica, estetica, etica e politica

L’ermeneutica filosofica di Hans-Georg Gadamer – indubbiamente uno dei capisaldi del pensiero novecentesco – rappresenta una filosofia molto composita, sfaccettata e articolata, per così dire formata da una molteplicità di dimensioni diverse che si intrecciano l’una con l’altra. Ciò risulta evidente già da un semplice sguardo alla composizione interna della sua opera principale, Wahrheit und Methode (1960), nella quale si presenta una teoria del comprendere che prende in esame tre differenti dimensioni dell’esperienza umana – arte, storia e linguaggio – ovviamente concepite come fondamentalmente correlate tra loro. Ma questo quadro d’insieme si complica notevolmente non appena si prendano in esame perlomeno alcuni dei numerosi contributi che Gadamer ha scritto e pubblicato prima e dopo il suo opus magnum: contributi che testimoniano l’importante presenza nel suo pensiero di altre tematiche. Di tale complessità, però, non sempre gli interpreti di Gadamer hanno tenuto pienamente conto, visto che una gran parte dei contributi esegetici sul suo pensiero risultano essenzialmente incentrati sul capolavoro del 1960 (ed in particolare sui problemi della legittimazione delle Geisteswissenschaften), dedicando invece minore attenzione agli altri percorsi che egli ha seguito e, in particolare, alla dimensione propriamente etica e politica della sua filosofia ermeneutica. Inoltre, mi sembra che non sempre si sia prestata la giusta attenzione alla fondamentale unitarietà – da non confondere con una presunta “sistematicità”, da Gadamer esplicitamente respinta – che a dispetto dell’indubbia molteplicità ed eterogeneità del pensiero gadameriano comunque vige al suo interno. La mia tesi, dunque, è che estetica e scienze umane, filosofia del linguaggio e filosofia morale, dialogo con i Greci e confronto critico col pensiero moderno, considerazioni su problematiche antropologiche e riflessioni sulla nostra attualità sociopolitica e tecnoscientifica, rappresentino le diverse dimensioni di un solo pensiero, le quali in qualche modo vengono a convergere verso un unico centro. Un centro “unificante” che, a mio avviso, va individuato in quello che potremmo chiamare il disagio della modernità. In altre parole, mi sembra cioè che tutta la riflessione filosofica di Gadamer, in fondo, scaturisca dalla presa d’atto di una situazione di crisi o disagio nella quale si troverebbero oggi il nostro mondo e la nostra civiltà. Una crisi che, data la sua profondità e complessità, si è per così dire “ramificata” in molteplici direzioni, andando ad investire svariati ambiti dell’esistenza umana. Ambiti che pertanto vengono analizzati e indagati da Gadamer con occhio critico, cercando di far emergere i principali nodi problematici e, alla luce di ciò, di avanzare proposte alternative, rimedi, “correttivi” e possibili soluzioni. A partire da una tale comprensione di fondo, la mia ricerca si articola allora in tre grandi sezioni dedicate rispettivamente alla pars destruens dell’ermeneutica gadameriana (prima e seconda sezione) ed alla sua pars costruens (terza sezione). Nella prima sezione – intitolata Una fenomenologia della modernità: i molteplici sintomi della crisi – dopo aver evidenziato come buona parte della filosofia del Novecento sia stata dominata dall’idea di una crisi in cui verserebbe attualmente la civiltà occidentale, e come anche l’ermeneutica di Gadamer possa essere fatta rientrare in questo discorso filosofico di fondo, cerco di illustrare uno per volta quelli che, agli occhi del filosofo di Verità e metodo, rappresentano i principali sintomi della crisi attuale. Tali sintomi includono: le patologie socioeconomiche del nostro mondo “amministrato” e burocratizzato; l’indiscriminata espansione planetaria dello stile di vita occidentale a danno di altre culture; la crisi dei valori e delle certezze, con la concomitante diffusione di relativismo, scetticismo e nichilismo; la crescente incapacità a relazionarsi in maniera adeguata e significativa all’arte, alla poesia e alla cultura, sempre più degradate a mero entertainment; infine, le problematiche legate alla diffusione di armi di distruzione di massa, alla concreta possibilità di una catastrofe ecologica ed alle inquietanti prospettive dischiuse da alcune recenti scoperte scientifiche (soprattutto nell’ambito della genetica). Una volta delineato il profilo generale che Gadamer fornisce della nostra epoca, nella seconda sezione – intitolata Una diagnosi del disagio della modernità: il dilagare della razionalità strumentale tecnico-scientifica – cerco di mostrare come alla base di tutti questi fenomeni egli scorga fondamentalmente un’unica radice, coincidente peraltro a suo giudizio con l’origine stessa della modernità. Ossia, la nascita della scienza moderna ed il suo intrinseco legame con la tecnica e con una specifica forma di razionalità che Gadamer – facendo evidentemente riferimento a categorie interpretative elaborate da Max Weber, Martin Heidegger e dalla Scuola di Francoforte – definisce anche «razionalità strumentale» o «pensiero calcolante». A partire da una tale visione di fondo, cerco quindi di fornire un’analisi della concezione gadameriana della tecnoscienza, evidenziando al contempo alcuni aspetti, e cioè: primo, come l’ermeneutica filosofica di Gadamer non vada interpretata come una filosofia unilateralmente antiscientifica, bensì piuttosto come una filosofia antiscientista (il che naturalmente è qualcosa di ben diverso); secondo, come la sua ricostruzione della crisi della modernità non sfoci mai in una critica “totalizzante” della ragione, né in una filosofia della storia pessimistico-negativa incentrata sull’idea di un corso ineluttabile degli eventi guidato da una razionalità “irrazionale” e contaminata dalla brama di potere e di dominio; terzo, infine, come la filosofia di Gadamer – a dispetto delle inveterate interpretazioni che sono solite scorgervi un pensiero tradizionalista, autoritario e radicalmente anti-illuminista – non intenda affatto respingere l’illuminismo scientifico moderno tout court, né rinnegarne le più importanti conquiste, ma più semplicemente “correggerne” alcune tendenze e recuperare una nozione più ampia e comprensiva di ragione, in grado di render conto anche di quegli aspetti dell’esperienza umana che, agli occhi di una razionalità “limitata” come quella scientista, non possono che apparire come meri residui di irrazionalità. Dopo aver così esaminato nelle prime due sezioni quella che possiamo definire la pars destruens della filosofia di Gadamer, nella terza ed ultima sezione – intitolata Una terapia per la crisi della modernità: la riscoperta dell’esperienza e del sapere pratico – passo quindi ad esaminare la sua pars costruens, consistente a mio giudizio in un recupero critico di quello che egli chiama «un altro tipo di sapere». Ossia, in un tentativo di riabilitazione di tutte quelle forme pre- ed extra-scientifiche di sapere e di esperienza che Gadamer considera costitutive della «dimensione ermeneutica» dell’esistenza umana. La mia analisi della concezione gadameriana del Verstehen e dell’Erfahrung – in quanto forme di un «sapere pratico (praktisches Wissen)» differente in linea di principio da quello teorico e tecnico – conduce quindi ad un’interpretazione complessiva dell’ermeneutica filosofica come vera e propria filosofia pratica. Cioè, come uno sforzo di chiarificazione filosofica di quel sapere prescientifico, intersoggettivo e “di senso comune” effettivamente vigente nella sfera della nostra Lebenswelt e della nostra esistenza pratica. Ciò, infine, conduce anche inevitabilmente ad un’accentuazione dei risvolti etico-politici dell’ermeneutica di Gadamer. In particolare, cerco di esaminare la concezione gadameriana dell’etica – tenendo conto dei suoi rapporti con le dottrine morali di Platone, Aristotele, Kant e Hegel – e di delineare alla fine un profilo della sua ermeneutica filosofica come filosofia del dialogo, della solidarietà e della libertà.

Max Bill in Italia . Lo spazio logico dell'architettura

I Max Bill is an intense giornata of a big fresco. An analysis of the main social, artistic and cultural events throughout the twentieth century is needed in order to trace his career through his masterpieces and architectures. Some of the faces of this hypothetical mural painting are, among others, Le Corbusier, Walter Gropius, Ernesto Nathan Rogers, Kandinskij, Klee, Mondrian, Vatongerloo, Ignazio Silone, while the backcloth is given by artistic avant-gardes, Bauhaus, International Exhibitions, CIAM, war events, reconstruction, Milan Triennali, Venice Biennali, the School of Ulm. Architect, even though more known as painter, sculptor, designer and graphic artist, Max Bill attends the Bauhaus as a student in the years 1927-1929, and from this experience derives the main features of a rational, objective, constructive and non figurative art. His research is devoted to give his art a scientific methodology: each work proceeds from the analysis of a problem to the logical and always verifiable solution of the same problem. By means of composition elements (such as rhythm, seriality, theme and its variation, harmony and dissonance), he faces, with consistent results, themes apparently very distant from each other as the project for the H.f.G. or the design for a font. Mathematics are a constant reference frame as field of certainties, order, objectivity: ‘for Bill mathematics are never confined to a simple function: they represent a climate of spiritual certainties, and also the theme of non attempted in its purest state, objectivity of the sign and of the geometrical place, and at the same time restlessness of the infinity: Limited and Unlimited ’. In almost sixty years of activity, experiencing all artistic fields, Max Bill works, projects, designs, holds conferences and exhibitions in Europe, Asia and Americas, confronting himself with the most influencing personalities of the twentieth century. In such a vast scenery, the need to limit the investigation field combined with the necessity to address and analyse the unpublished and original aspect of Bill’s relations with Italy. The original contribution of the present research regards this particular ‘geographic delimitation’; in particular, beyond the deep cultural exchanges between Bill and a series of Milanese architects, most of all with Rogers, two main projects have been addressed: the realtà nuova at Milan Triennale in 1947, and the Contemporary Art Museum in Florence in 1980. It is important to note that these projects have not been previously investigated, and the former never appears in the sources either. These works, together with the most well-known ones, such as the projects for the VI and IX Triennale, and the Swiss pavilion for the Biennale, add important details to the reference frame of the relations which took place between Zurich and Milan. Most of the occasions for exchanges took part in between the Thirties and the Fifties, years during which Bill underwent a significant period of artistic growth. He meets the Swiss progressive architects and the Paris artists from the Abstraction-Création movement, enters the CIAM, collaborates with Le Corbusier to the third volume of his Complete Works, and in Milan he works and gets confronted with the events related to post-war reconstruction. In these years Bill defines his own working methodology, attaining an artistic maturity in his work. The present research investigates the mentioned time period, despite some necessary exceptions. II The official Max Bill bibliography is naturally wide, including spreading works along with ones more devoted to analytical investigation, mainly written in German and often translated into French and English (Max Bill himself published his works in three languages). Few works have been published in Italian and, excluding the catalogue of the Parma exhibition from 1977, they cannot be considered comprehensive. Many publications are exhibition catalogues, some of which include essays written by Max Bill himself, some others bring Bill’s comments in a educational-pedagogical approach, to accompany the observer towards a full understanding of the composition processes of his art works. Bill also left a great amount of theoretical speculations to encourage a critical reading of his works in the form of books edited or written by him, and essays published in ‘Werk’, magazine of the Swiss Werkbund, and other international reviews, among which Domus and Casabella. These three reviews have been important tools of analysis, since they include tracks of some of Max Bill’s architectural works. The architectural aspect is less investigated than the plastic and pictorial ones in all the main reference manuals on the subject: Benevolo, Tafuri and Dal Co, Frampton, Allenspach consider Max Bill as an artist proceeding in his work from Bauhaus in the Ulm experience . A first filing of his works was published in 2004 in the monographic issue of the Spanish magazine 2G, together with critical essays by Karin Gimmi, Stanislaus von Moos, Arthur Rüegg and Hans Frei, and in ‘Konkrete Architektur?’, again by Hans Frei. Moreover, the monographic essay on the Atelier Haus building by Arthur Rüegg from 1997, and the DPA 17 issue of the Catalonia Polytechnic with contributions of Carlos Martì, Bruno Reichlin and Ton Salvadò, the latter publication concentrating on a few Bill’s themes and architectures. An urge to studying and going in depth in Max Bill’s works was marked in 2008 by the centenary of his birth and by a recent rediscovery of Bill as initiator of the ‘minimalist’ tradition in Swiss architecture. Bill’s heirs are both very active in promoting exhibitions, researching and publishing. Jakob Bill, Max Bill’s son and painter himself, recently published a work on Bill’s experience in Bauhaus, and earlier on he had published an in-depth study on ‘Endless Ribbons’ sculptures. Angela Thomas Schmid, Bill’s wife and art historian, published in end 2008 the first volume of a biography on Max Bill and, together with the film maker Eric Schmid, produced a documentary film which was also presented at the last Locarno Film Festival. Both biography and documentary concentrate on Max Bill’s political involvement, from antifascism and 1968 protest movements to Bill experiences as Zurich Municipality councilman and member of the Swiss Confederation Parliament. In the present research, the bibliography includes also direct sources, such as interviews and original materials in the form of letters correspondence and graphic works together with related essays, kept in the max+binia+jakob bill stiftung archive in Zurich. III The results of the present research are organized into four main chapters, each of them subdivided into four parts. The first chapter concentrates on the research field, reasons, tools and methodologies employed, whereas the second one consists of a short biographical note organized by topics, introducing the subject of the research. The third chapter, which includes unpublished events, traces the historical and cultural frame with particular reference to the relations between Max Bill and the Italian scene, especially Milan and the architects Rogers and Baldessari around the Fifties, searching the themes and the keys for interpretation of Bill’s architectures and investigating the critical debate on the reviews and the plastic survey through sculpture. The fourth and last chapter examines four main architectures chosen on a geographical basis, all devoted to exhibition spaces, investigating Max Bill’s composition process related to the pictorial field. Paintings has surely been easier and faster to investigate and verify than the building field. A doctoral thesis discussed in Lausanne in 1977 investigating Max Bill’s plastic and pictorial works, provided a series of devices which were corrected and adapted for the definition of the interpretation grid for the composition structures of Bill’s main architectures. Four different tools are employed in the investigation of each work: a context analysis related to chapter three results; a specific theoretical essay by Max Bill briefly explaining his main theses, even though not directly linked to the very same work of art considered; the interpretation grid for the composition themes derived from a related pictorial work; the architecture drawing and digital three-dimensional model. The double analysis of the architectural and pictorial fields is functional to underlining the relation among the different elements of the composition process; the two fields, however, cannot be compared and they stay, in Max Bill’s works as in the present research, interdependent though self-sufficient. IV An important aspect of Max Bill production is self-referentiality: talking of Max Bill, also through Max Bill, as a need for coherence instead of a method limitation. Ernesto Nathan Rogers describes Bill as the last humanist, and his horizon is the known world but, as the ‘Concrete Art’ of which he is one of the main representatives, his production justifies itself: Max Bill not only found a method, but he autonomously re-wrote the ‘rules of the game’, derived timeless theoretical principles and verified them through a rich and interdisciplinary artistic production. The most recurrent words in the present research work are synthesis, unity, space and logic. These terms are part of Max Bill’s vocabulary and can be referred to his works. Similarly, graphic settings or analytical schemes in this research text referring to or commenting Bill’s architectural projects were drawn up keeping in mind the concise precision of his architectural design. As for Mies van der Rohe, it has been written that Max Bill took art to ‘zero degree’ reaching in this way a high complexity. His works are a synthesis of art: they conceptually encompass all previous and –considered their developments- most of contemporary pictures. Contents and message are generally explicitly declared in the title or in Bill’s essays on his artistic works and architectural projects: the beneficiary is invited to go through and re-build the process of synthesis generating the shape. In the course of the interview with the Milan artist Getulio Alviani, he tells how he would not write more than a page for an essay on Josef Albers: everything was already evident ‘on the surface’ and any additional sentence would be redundant. Two years after that interview, these pages attempt to decompose and single out the elements and processes connected with some of Max Bill’s works which, for their own origin, already contain all possible explanations and interpretations. The formal reduction in favour of contents maximization is, perhaps, Max Bill’s main lesson.

Gadda neobarocco. Corrispondenze fra Barocco storico e Barocco moderno

Nei primi due capitoli mi occupo del recupero del Barocco in ambito novecentesco e delle diverse letture e interpretazioni del Barocco e del Neobarocco, concetto che nasce dalla riflessione sul Barocco lungo tutto il Novecento. Riflessione che è stata anche una rivendicazione, a livello estetico, ma non solo, di una attualità o contemporaneità del Barocco, che accomuna tutta la riflessione sulla scoperta della cultura di un secolo, da Wölfflin a Benjamin, da Riegl a Anceschi. Si tratta anche di un rapporto fra Barocco storico e Neobarocco: se la stessa rivalutazione e riscoperta dell’arte del XVII secolo, dalla fine dell’Ottocento e lungo tutto il Novecento, ha coinciso con la sua costruzione terminologica ed ermeneutica, di questa nuova categoria è lo stesso approccio intellettuale contemporaneo che può definirsi, nella più ampia accezione, «neobarocco». Nel terzo capitolo, invece, ho approfondito il rapporto fra Gadda e il Barocco, partendo dal concetto di allegoria moderna di Walter Benjamin. Fondamentale per la mia ricerca è stato il libro di Gilles Deleuze, La piega. Leibniz e il barocco, che ha visto nell’opera del filosofo Leibniz (studiato anche dal proprio Gadda) la chiave di lettura per capire il Barocco nelle sue diverse manifestazioni. E anche il libro di Robert Dombroski, Gadda e il barocco, in cui si parte appunto dal concetto di barocco/neobarocco come punto di approccio per studiare il barocco di Gadda. Infatti, lo stile di Gadda risponde al canone barocco che il poststrutturalismo ha riaccolto nel vivo del dibattito estetico, si pensi ai contributi di Roland Barthes e di Severo Sarduy e, posteriormente, all’opera proprio di Deleuze. Nell’ultimo capitolo, poi, faccio un’analisi di Gadda traduttore di opere del Seicento spagnolo, opere che vengono da lui riscritte grazie alla rielaborazione del passato attraverso il suo linguaggio neobarocco.

Il Foro Bonaparte: l'architettura della citta'

La ricerca ha per oggetto il progetto del Foro Bonaparte a Milano redatto da Giovanni Antonio Antolini a seguito del decreto del 23 giugno 1800 che stabiliva l’abbattimento delle mura del Castello Sforzesco. Si affronta il tema dell’architettura avendo come obiettivo una lettura critica di tale progetto servendosi dell’analisi compositiva come strumento in grado di stabilire i rapporti che intercorrono tra la città, l’architettura e il tipo. Attraverso lo studio del progetto urbano la ricerca conferma l’ipotesi per la quale la grande forma totalizzante, perentoria e assoluta è capace di mutare la struttura urbana, offrendo un nuovo modello con cui rinnovare la città. L’ambizione di Antolini di veder realizzata l’opera è destinata a svanire nell’arco di pochi anni, ma il progetto per il Foro Bonaparte continuerà per lungo tempo ad evocare la sua idea innovativa fino ai giorni nostri. Sebbene l’opera sia destinata a rimanere un’architettura solo disegnata, le varie pubblicazioni continuano a circolare nelle accademie prima e nelle università successivamente, costituendo un importante patrimonio di studio e di ricerca per generazioni di architetti, fino alla riscoperta avvenuta con Aldo Rossi e Manfredo Tafuri negli anni sessanta del secolo scorso. Dalle lezioni formulate nelle architetture del passato è possibile avanzare nuove ipotesi e alimentare riflessioni e dibattiti sul ruolo dell’architettura nella città contemporanea. La ricerca si occupa del progetto d’architettura per offrire un ulteriore contributo al tema, attraverso una lettura di carattere compositivo, supportata da una serie di schemi e disegni di studio necessari per completare il testo e per verificare i concetti esposti. Dopo aver raccolto, catalogato ed analizzato il materiale iconografico relativo al progetto per il Foro Bonaparte si è scelto di basare il ridisegno sulla raccolta di disegni conservati presso la Biblioteca Nazionale di Francia.

Métamorphoses de l'Image des Tartares dans la littérature européenne du XXème siècle

Ce travail doctoral analyse le changement de l’image des Tartares dans la littérature européenne en langue allemande, anglaise, française et italienne du XXe siècle par l’étude de trois figures : la horde mongole, Gengis-khan et Khoubilaï-khan. Il soutient la thèse que, grâce à quelques facteurs historico-culturels comme la remise en question du concept de barbarie, l’essor des totalitarismes, l’ouverture de la Mongolie vers l’Occident, la redécouverte de l’Histoire secrète des Mongols et la fortune de Le divisament dou monde, au cours du XXe siècle, l’image littéraire des gengiskhanides de négative devient positive. Cette étude se compose d’une introduction, de trois chapitres et d’une conclusion. Dans l’introduction, on analyse la formation de l’image des Tartares et son évolution jusqu’à la fin du XIXe siècle, on retrace les facteurs historico-culturels qui la remettent au goût du jour et en provoquent le changement au XXe siècle et on présente le travail. Dans le premier chapitre, on se penche sur la prosopographie des Tartares dans les textes littéraires du XXe siècle, en la confrontant avec leur représentation dans l’art contemporain. Dans le deuxième chapitre, on étudie la façon des Tartares de se rapporter aux autres au sein de la société dans les textes littéraires du XXe siècle. Dans le troisième chapitre, on examine les lieux des gengiskhanides dans les textes littéraires du XXe siècle. Enfin, dans la conclusion, les données acquises au moyen de l’analyse conduite sont confrontées et interprétées. Le changement de l’image des Tartares va de pair avec une Europe qui, après avoir fait l’expérience de deux guerres mondiales, avoir assisté aux revendications de la décolonisation et avoir introjecté la thèse freudienne du « malaise dans la civilisation », remet en discussion sa façon de concevoir la barbarie et l’Altérité.

The Republican Alternative. The Netherlands and Switzerland Compared

The Republican Alternative seeks to move beyond the mere notion of scholarly inquiry into the republic—the subject of recent rediscovery by political historians interested in Europe’s intellectual heritage—by investigating the practical similarities and differences between two early modern republics, as well as their self-images and interactions during the turbulent seventeenth and eighteenth centuries. Among the world’s most economically successful societies, Switzerland and the Netherlands laid much of the foundation for their prosperity during the early modern period discussed here. This volume attempts to clarify the special character of these two countries as they developed, including issues of religious plurality, the republican form of government, and an increasingly commercially-driven agrarian society.

An Optical Survey for Space Debris on Highly Eccentric MEO Orbits

Optical surveys for space debris in high-altitude orbits have been conducted since more than ten years. Originally these efforts concentrated mainly on the geostationary ring (GEO). Corresponding observation strategies, processing techniques and cataloguing approaches have been developed and successfully applied. The ESA GEO surveys, e.g., resulted in the detection of a significant population of small-size debris and later in the discovery of high area-to-mass ratio objects in GEO-like orbits. The observation scenarios were successively adapted to survey the geostationary transfer orbit (GTO) region; and recently surveys to search for debris in the medium Earth orbit (MEO) region of the global navigation satellite constellations were successfully conducted. Comparably less experience (both, in terms of practical observation and strategy definition) is available for eccentric orbits that (at least partly) are in the MEO region, in particular for the Molniya-type orbits. Several breakup events and deliberate fragmentations are known to have taken place in such orbits. Different survey and follow-up strategies for searching space debris objects in highly-eccentric MEO orbits, and to acquire orbits which are sufficiently accurate to catalogue such objects and to maintain their orbits over longer time spans were developed. Simulations were performed to compare the performance of different survey and cataloguing strategies. Eventually, optical observations were conducted in the framework of an ESA study using ESA’s Space Debris Telescope (ESASDT) the 1-m Zeiss telescope located at the Optical Ground Station (OGS) at the Teide Observatory at Tenerife, Spain. A first series of surveys of Molnjya-type orbits was performed between January and April 2013. During these four months survey observations were performed during nine nights. A basic survey consisted of observing a single geocentric field for 10 minutes. If a faint object was found, follow-up observations were performed during the same night to ensure a save rediscovery of the object during the next nights. Additional follow-up observations to maintain the orbits of these newly discovered faint objects were also acquired with AIUB ́s 1m ZIMLAT telescope in Zimmerwald, Switzerland. Eventually 195 basic surveys were performed during these nine nights corresponding to about 32.5 hours of observations. In total 24 uncorrelated faint objects were discovered and all known catalogue objects in the survey fields were detected. On average one uncorrelated object was found every 80 minutes. Some of these objects show a considerable brightness variation and have a high area-to-mass ratio as determined in the orbit estimation process.

Tab. 1: Results of the movement measurements on the blue ice-field Blåisen

In January/February 1985 a German-South African expedition had the opportunity to repeat measurements made by means of stakes planted in 1951 (Norwegian-British-Swedish Antarctic Expedition 1949-52) and 1966 (SANAE VII). Although the rediscovery of the old stakes had not been expected, the stakes could be identified and it was possible to derive movement vectors on the basis of old and heterogenic measurement data. The long-term movement rates established basically confirm and complement the values determined in 1951. The flow rates of 9,1 cm/a to 66.4 cm/a proved to be extremly low. Observations of the stake lengths showed very little accumulation in the fringe areas of the blue ice-field (ca. 0.7 to 2.6 cm/a snow/firn); on bare ice an ablation of 2.6 cm/a water equivalent (2.9 cm/a ice) was measured. The paper begins with a description of the essential conditions for the formation of the blue ice-field. Subsequently the measurements are explained in detail and their results are discussed.

Contexto, criptoanálisis y propuesta de solución de la inscripción de la talla (original) de la Virgen de Candelaria de Tenerife (Canarias, España)

Esta investigación es un ejemplo de simbiosis entre criptoanálisis y desciframiento de lenguas. Es la búsqueda del sentido de una inscripción, un conjunto de casi doscientas letras latinas, en una talla de la Virgen María que estaba en la isla de Tenerife, en la localidad hoy de Candelaria, en las islas Canarias. La imagen desapareció en un temporal en el año 1826. No obstante, es posible lograr una gran certeza sobre qué letras tenía, acudiendo a las fuentes documentales textuales y artísticas. El conocimiento del significado, si lo hubiera, de la inscripción mariana, creemos que no puede lograrse sin la adecuada comprensión del contexto. Esto significa indagar en la historia de la misma talla, que se remonta hasta el siglo XIV o XV, en el estudio de la población autóctona canaria, así como de los pueblos que allí llegaron en sus diferentes momentos históricos. Además, es necesario conocer el redescubrimiento del archipiélago canario y sus procesos de conquista y evangelización. Todos estos datos irán ofreciendo un panorama nuevo y sorprendente para comprender no sólo las letras sino la misma imagen escultórica en madera. A partir de este momento la indagación se moverá en ver si las letras corresponden a alguna lengua posible, lo que nos ha llevado a analizar un amplísimo conjunto de textos lo más cercanos a la época bajo estudio, pertenecientes a alrededor de un centenar de lenguas. Tras el examen lingüístico se ha procedido a un estudio de las posibles formas criptográficas que se hubieran utilizado para generar el texto de la inscripción. Se ofrece un detallado y minucioso elenco de técnicas posibles que pudieran haberse adoptado y se criptoanaliza con exhaustividad las letras de la talla mariana. Al mismo tiempo se ofrece un nuevo marco criptológico de métodos y sistemas más ordenado y completo que el que hasta ahora venía considerándose, en especial desde el surgimiento de la criptografía de clave asimétrica. Continuamos la investigación sopesando la posible generación pseudo-aleatoria del texto, un texto que pudiera no tener sentido alguno. En este momento, y habiendo completado todas las posibilidades e hipótesis, habiéndose negado todas, volvemos a reconsiderar el cuerpo de conjeturas y supuestos. Desde ahí analizamos en profundidad el ámbito etnográfico y lingüístico bereber como hipótesis más plausible y probable. Tras la profundización en esta lengua y la corrección de los errores que nos llevaron a no detectarla en nuestro análisis precedente, llegamos a la conclusión de encontrarnos ante una lengua arcaica bereber, un conjunto de letras pertenecientes a una lengua y familia hoy no desaparecida, si bien muy modelada y difuminada por otras lenguas, en especial el árabe. Esto nos llevará a rescatar aspectos léxicos, morfológicos, sintácticos y fonéticos de este habla arcaica. Con todos estos datos realizamos un amplio estudio semántico de la talla tanto desde la perspectiva aborigen autóctona como cristiana. Finalmente, desde las voces lexicales y sus raíces de las lenguas bereberes e insulares amazigh, ofrecemos el significado de las letras inscritas en la talla mariana de Candelaria. ABSTRACT This research is an example of symbiosis between cryptanalysis and deciphering of languages. It is the search for meaning in an inscription, a group of about two hundred latin letters on a carving of the Virgin Mary that was on the island of Tenerife, in the town of Candelaria today, in the Canary islands. The image disappeared in a storm in 1826. However, it is possible to achieve a great certainty about what letters had, going to the textual and artistic documentary sources. The knowledge of the meaning, if any, of the marian inscription, can not be achieved without an adequate knowledge of the context. This means researching into the history of the same carving, which dates back to the fourteenth and fifteen century; the study of the canarian indigenous people and of the people who came there at different historical moments. Furthermore, it is necessary to know the rediscovery of the Canary islands and their processes of conquest and evangelization. All these data will offer a new and surprising outlook to understanding not only the letters but the same wood sculpture. From this moment the inquiry will move to see if the letters correspond to any possible language, which has led us to analyze a very large set of texts as close to the time under study, in a hundred languages. After the language examination, has been carried out a study of possible cryptographic forms used to generate the text of the inscription. A detailed and thorough list of possible techniques that could be adopted is offered. Then exhaustively we cryptanalyze the letters of the marian carving. At the same time a new crypto framework of methods and systems more orderly and complete, especially since the emergence of asymmetric key cryptography, is provided. We continue researching the possible pseudo-random generation of the text, a text that would not make any sense. At this time, and having completed all the possibilities and hypotheses, all having refused, we return to rethink our assumptions. From there we analyze in depth the ethnographic and linguistic berber sphere as the most likely hypothesis. Following the deepening of this language and correcting the mistakes that led us not to detect it in our analysis above, we conclude that this is an archaic berber language, a set of letters belonging to a language and family not extinct today but very modeled and influenced by other languages, primarily arabic. This will lead us to rescue lexical, morphological, syntactic and phonetic aspects of this archaic speech. With all this data we make a wide semantic study of the carving from the indigenous and christian perspective. Finally, from the lexical voices and roots of the berber languages amazigh and island-amazigh, we give the meaning of the letters inscribed in the marian carving of Candelaria.

Advances in apoptosis research

Apoptosis, also called programmed cell death, has attracted great attention in recent years. After its discovery by Carl Vogt in 1842, apoptosis research was dormant for more than a century. Its rediscovery in the second half of this century, and the coining of the term apoptosis in 1972 by Kerr, Wyllie, and Currie, ignited an unparalleled interest in this field of science. The number of publications related to apoptosis has been growing exponentially every year ever since. This is mainly due to three major advances, two of which have been made recently and one that is currently seen. First, studies with the small nematode Caenorhabditis elegans have identified a number of apoptosis regulating genes—the first evidence that cell death is an active process under genetic control. Many of these genes have mammalian homologs that, like their worm counterparts, seem to regulate mammalian apoptosis. Second, elucidation of the signal transduction pathways of apoptosis has lead especially to the identification of specific death signaling molecules such as a new family of cysteine proteases, the caspases. Third, it has now become clear that many diseases are characterized by dysregulation of apoptotic programs. Many of these programs involve a family of receptors and their ligands, the death receptor/ligand family. The hope now is to interfere with apoptosis regulation in these systems and to develop new therapeutic concepts.

Georges de La Tour : the Status of Scholarship

Seventeenth-century French painter, Georges de La Tour, was a forgotten artist. His rediscovery in the nineteenth century set off a firestorm of research and a hunt to find more works by the artist. One problem after another arose as scholars attempted to define the artist by his works, his style, and the remnants of his personal history.

Central Asia on New Delhi's Geostrategic Radar. EUCAM Commentary No. 18, October 2011

Central Asia today holds much strategic interest for India as an emerging 21st Century regional and global power. Despite being a latecomer in what some see as a new ‘Great Game’, New Delhi is keen to reconstruct the ‘Silk Route’. While Indo-Central Asian relations go back to antiquity when cultural, commercial and political ties thrived, post-independence India was physically cut off from Afghanistan and West Asia. It remained embroiled in domestic preoccupations and the insurgency in Jammu and Kashmir, all of which led to a limited foreign policy until the early nineties and a belated rediscovery of the region.

Lugares de memoria y lugares de amnesia : La familia como colectivo amnésico en Os libros arden mal de Manuel Rivas

A lo largo de los últimos años, la expresión "memoria histórica" resulta omnipresente en el discurso político, social y cultural europeo. Cuando, en el caso de España, se menciona la "memoria histórica" los acontecimientos a que se refiere en la mayoría de los casos son la Guerra Civil (1936-1939) y el Franquismo (1939-1975), acontecimientos cuya memoria nunca pierde su actualidad y necesidad. A partir del año 2000 se inició la apertura pública al pasado oculto y reprimido que lleva consigo la liberación de los recuerdos que habían permanecido marginados e ignorados hasta ahora. La obra del autor gallego Manuel Rivas forma parte de este proceso de recuperación de la memoria histórica y pone su enfoque, precisamente, en ese pasado incómodo que tantos años ha permanecido oculto para contribuir a la reivindicación de la memoria de las víctimas de la represión franquista. En Os libros arden mal (2006), Manuel Rivas ofrece un panorama complejo y diverso del pasado traumático. A través de la confrontación de diferentes comunidades de memoria -en muchos casos antagonistas- elabora la historia vivida por los ciudadanos coruñeses. Con referencia a los conceptos correspondientes a la memoria colectiva desarrollada en las Ciencias Sociales y Culturales, este artículo tiene la intención de estudiar la memoria de la Guerra Civil y el Franquismo a partir del análisis de una de las familias retratadas en la novela.

Primary aldosteronism - actual epidemics or false alarm?

The prevalence of "primary aldosteronism" (PAL) cannot be precisely determined at this time, given 1) lack of a universally accepted definition, and 2) normotensive as well as normokalemic phases in the evolutionary development of a disease eventually characterized by hypertension and hypokalemia. The exception is fully genetically characterised forms such as glucocorticoid-suppressible hyperaldosteronism, the true prevalence of which could be proven today by universal screening using a single blood sample, but this is neither practical nor appropriate. Controversy has arisen regarding the rareness, or otherwise, of PAL because of 1) rediscovery in the last 12 years of the normokalemic phase described by Conn, 2) application of widely available methods for measurement of aldosterone and renin to "screening", 3) variable quality of these methods, and of their application, and 4) lack of the necessary "diagnostic", in addition to "screening", tests in some studies. PAL is significantly more common than previously thought, and a very important potentially curable form of hypertension. Early diagnosis and specific treatment avoids morbidity. The current focus on increased detection is essential, and will help to resolve the question of prevalence.

Habitat use by Darling Downs population of the grassland earless dragon: implications for conservation.

A population of the grassland earless dragon (Tympanocryptis pinguicolla) on the Darling Downs, Queensland, Australia, had been considered extinct until its recent rediscovery. We determined factors affecting grassland earless dragon abundance and prey availability in 3 habitats. Mean dragon body condition and prey numbers were higher in sorghum than grasslands and grass verges. Poisson regression analyses indicated that the dragon numbers were 10 times higher in sorghum, and that this may result from differences in prey numbers as well as other habitat conditions. Tracking data indicated selection of open versus closed microhabitat. Sorghum planted in rows provided alternating open and closed microhabitats for optimal thermoregulation conditions. Grasslands and grass verges were more uniformly shaded. Of individuals we tracked in the sorghum stubble, 85.7% used litter as overnight refuges. Litter was abundant in sorghum and sparse in grass habitats. The practices of minimum tillage and resting stubble strips possibly mitigate agricultural impacts on dragons and provide continuous access to suitable habitat. Changes in agricultural practices that affect the habitat suitability will potentially have detrimental impacts on the population. Our data suggest that conservation efforts be focused on maintaining suitability of habitats in crop fields. We recommend monitoring dragon abundance at control and trial sites of any new agricultural practices; this will provide opportunity to modify or stop undesirable practices before adoption by farmers. Conservation agencies may use our data as a baseline for monitoring long-term viability of the population.
