Josep Claret: arquitectura i societat

El gironí Josep Claret Rubira (1908-1988), arquitecte de professió i artista-dibuixant de vocació, va obtenir el títol l'any 1933, a l'Escola d'Arquitectura de Barcelona. D'ençà d'aquella data i fins a mitjan dels anys 70, va projectar una quantitat enorme d'edificis de múltiples tipologies i nombrosos plans d'urbanització, arreu de les comarques gironines i menorquines. Amb ideologia primerenca propera a les esquerres catalanistes, es va haver d'adaptar al règim franquista, per poder continuar treballant i vivint a Catalunya. Malgrat que inicialment li deuria costar un gran esforç, el procés d'amotllament el va tenir planer (almenys aparentment), gràcies al seu parentiu -per via matrimonial- amb una família que hi estava estretament vinculada. És autor d'obres d'elevat nivell arquitectònic -amb poques que siguin conegudes i reconegudes- i un clar conformador del paisatge de les seves contrades, fet influent en la societat que hi ha estat habitant i que hi viu encara avui dia. La seva arquitectura és un magnífic exemple del que agradava a les generacions de durant cinc dècades. És també autor d'obres que, moltes vegades, no s'adiuen gens amb el que la Història de l'Arquitectura dóna per bones, però que reflecteixen el gust, les preferències i les prioritats d'una societat determinada.

The dark side of the Mediterranean : expression of fear from the inquisition to the present

Inside the stones of its most famous buildings, Évora keeps mysteries and secrets which constitute the most hidden side of its cultural identity. A World Heritage site, this town seems to preserve, in its medieval walls, a precious knowledge of the most universal and ancient human emotion: fear. Trying to transcend many of its past and future fears, some of its historical monuments in Gothic style were erected against the fear of death, the most terrible of all fears, which the famous inscription, in the Bones Chapel of the Church of São Francisco, insistently reminds us, through the most disturbing words: “Nós ossos que aqui estamos pelos vossos esperamos”. If the first inquisitors worked in central Europe (Germany, northern Italy, eastern France), later the centres of the Inquisition were established in the Mediterranean regions, especially southern France, Italy, Portugal, and Spain. Consequently, the roots of fear in Évora are common to other towns, where the Inquisition developed a culture of fear, through which we can penetrate into the dark side of the Mediterranean, where people were subjected to the same terrifying methods of persecution and torture. This common geographical and historical context was not ignored by one of the most famous masters of American gothic fiction, Edgar Allan Poe. Through the pages of The Pit and the Pendulum, readers get precise images of the fearful instruments of terror that were able to produce the legend that has made the first grand inquisitor, Tomas de Torquemada, a symbol of ultimate cruelty, bigotry, intolerance, and religious fanaticism, which unfortunately are still the source of our present fears in a time when religious beliefs can be used again as a motif of war and destruction. As Krishnamurti once suggested, only a fundamental realization of the root of all fear can free our minds.

Maturidade de plataformas SOA Open Source vs proprietários

O bom funcionamento de uma empresa passa pela coordenação dos seus vários elementos, pela fluidez das suas operações diárias, pelo desempenho dos seus recursos, tanto humanos como materiais, e da interacção dos vários sistemas que a compõem. As tecnologias empresariais sentiram um desenvolvimento contínuo após a sua aparição, desde o processo básico, para gestão de processos de negócios (BPM), para plataformas de recursos empresariais (ERP) modernos como o sistema proprietário SAP ou Oracle, para conceitos mais gerais como SOA e cloud, baseados em standards abertos. As novas tecnologias apresentam novos canais de trânsito de informação mais rápidos e eficientes, formas de automatizar e acompanhar processos de negócio e vários tipos de infra-estruturas que podem ser utilizadas de forma a tornar a empresa mais produtiva e flexível. As soluções comerciais existentes permitem realizar estes objectivos mas os seus custos de aquisição podem revelar-se demasiado elevados para algumas empresas ou organizações, que arriscam de não se adaptar às mudanças do negócio. Ao mesmo tempo, software livre está a ganhar popularidade mas existem sempre alguns preconceitos sobre a qualidade e maturidade deste tipo de software. O objectivo deste trabalho é apresentar SOA, os principais produtos SOA comerciais e open source e realizar uma comparação entre as duas categorias para verificar o nível de maturidade do SOA open source em relação às soluções SOA proprietárias.

The known unknowns and the unknown unknowns of the EMU. Bruegel Policy Contribution 2012/18, October 2012

Extensive prior research on the economics of European monetary union highlighted some potential risks (the known unknowns) but overlooked others (the unknown unknowns). Asymmetries among participating countries, the potentially destabilising character of a one-size-fits all monetary policy, the weakness of adjustment mechanisms, the lack of incentives for fiscal discipline, the possibility of sovereign solvency crises and their adverse consequences were all known and understood. But policymakers often relied on a complacent reading of the evidence. • The potential for financial disruption was vastly underestimated. Economists generally did not consider, or underestimated, the possibility of balance of payment crises such as those experienced by southern European countries, or the risk of a feedback loop between banks and sovereigns. • Remedying EMU’s systemic deficiencies is on the policy agenda. Banking union would go a long way towards addressing the fault lines. The urgent question for economists is if it is going to be enough and, if not, what else should complement the ‘bare-bones’ EMU of Maastricht.

Endocranial lesions: their distribution and aetiology

Reactive new bone on the endocranial surface of the skull in non-adults has recently received a lot of attention in the palaeopathological literature. These features appear as layers of new bone on the original cortical surface, expanding around meningeal vessels, as isolated plaques, 'hair-on-end' extensions of the diploe or, as 'capillary' impressions extending into the inner lamina of the cranium. These lesions are commonly found on the occipital bone, outlining the cruciate eminence, but have also been recorded on the parietal and frontal bones, and appear to follow the areas of venous drainage. Although recognized as resulting from haemorrhage or inflammation, their precise aetiology is still a matter of controversy. This paper outlines their possible causes and examines their nature and distribution in a group of non-adults from four archaeological sites in England. It is recommended that, when recording these lesions in the future, additional skeletal pathologies, the age of the child, and nature and distribution of the lesions also be taken into account.

A traitor's death? The identity of a drawn, hanged and quartered man from Hulton Abbey, Staffordshire

Analysis of a set of bones redeposited in a medieval abbey graveyard showed that the individual had been beheaded and chopped up, and this in turn suggested one of England's more gruesome I execution practices. Since quartering was generally reserved for the infamous, the author attempts to track down the victim and proposes him to be Hugh Despenser, the lover of King Edward II.

Equivalent noise level generated by drilling onto the ossicular chain as measured by laser Doppler vibrometry: A temporal bone study

Background: Inadvertent drilling on the ossicular chain is one of the causes of sensorineural hearing loss (HL) that may follow tympanomastoid surgery. A high-frequency HL is most frequently observed. It is speculated that the HL is a result of vibration of the ossicular chain resembling acoustic noise trauma. It is generally considered that using a large cutting burr is more likely to cause damage than a small diamond burr. Aim: The aim was to investigate the equivalent noise level and its frequency characteristics generated by drilling onto the short process of the incus in fresh human temporal bones. Methods and Materials: Five fresh cadaveric temporal bones were used. Stapes displacement was measured using laser Doppler vibrometry during short drilling episodes. Diamond. and cutting burrs of different diameters were used. The effect of the drilling on stapes footplate displacement was compared with that generated by an acoustic signal. The equivalent noise level (dB sound pressure level equivalent [SPL eq]) was thus calculated. Results: The equivalent noise levels generated ranged from 93 to 125 dB SPL eq. For a 1-mm cutting burr, the highest equivalent noise level was 108 dB SPL eq, whereas a 2.3-mm cutting burr produced a maximal level of 125 dB SPL eq. Diamond burrs generated less noise than their cutting counterparts, with a 2.3-mm diamond burr producing a highest equivalent noise level of 102, dB SPL eq. The energy of the noise increased at the higher end of the frequency spectrum, with a 2.3-mm cutting burr producing a noise level of 105 dB SPL eq at 1 kHz and 125 dB SPL eq at 8 kHz. In contrast, the same sized diamond burr produced 96 dB SPL eq at 1 kHz and 99 dB at 8 kHz. Conclusion:This study suggests that drilling on the ossicular chain can produce vibratory force that is analogous with noise levels known to produce acoustic trauma. For the same type of burr, the larger the diameter, the greater the vibratory force, and for the same size of burr, the cutting burr creates more vibratory force than the diamond burr. The cutting burr produces greater high-frequency than lower-frequency vibratory energy.

The effects of mass loading the ossicles with a floating mass transducer on middle ear transfer function

Hypothesis: The aim of this study was to measure the mass loading effect of an active middle-ear implant (the Vibrant Soundbridge) in cadaver temporal bones. Background: Implantable middle ear hearing devices such as Vibrant Soundbridge have been used as an alternative to conventional hearing aids for the rehabilitation of sensorineural hearing loss. Other than the obvious disadvantage of requiring implantation middle ear surgery, it also applies a direct weight on the ossicular chain which, in turn, may have an impact on residual hearing. Previous studies have shown that applying a mass directly on the ossicular chain has a damping effect on its response to sound. However, little has been done to investigate the magnitude and the frequency characteristics of the mass loading effect in devices such as the Vibrant Soundbridge. Methods: Five fresh cadaver temporal bones were used. The stapes displacement was measured using laser Doppler vibrometry before and after the placement of a Vibrant Sound-bridge floating mass transducer. The effects of mass and attachment site were compared with the unloaded response. Measurements were obtained at frequencies between 0.1 and 10 kHz and at acoustic input levels of 100 dB sound pressure level. Each temporal bone acted as its own control. Results: Placement of the floating mass transducer caused a reduction of the stapes displacement. There were variations between the bones. The change of the stapes displacement varied from 0 dB to 28 dB. The effect was more prominent at frequencies above 1,000 Hz. Placing the floating mass transducer close to the incudostapedial joint reduced the mass loading effect. Conclusion: The floating mass transducer produces a measurable reduction of the stapes displacement in the temporal bone model. The effect is more prominent at high frequencies.

Thalassaemia: its diagnosis and interpretation in past skeletal populations

The diagnosis of thalassaemia in archaeological populations has long been hindered by a lack of pathogonomic features, and the non-specific nature of cribra orbitalia and porotic hyperostosis. In fact, clinical research has highlighted more specific diagnostic criteria for thalassaemia major and intermedia based on changes to the thorax (‘rib-within-a-rib’ and costal osteomas). A recent re-examination of 364 child skeletons from Romano-British Poundbury Camp, Dorset revealed children with general ‘wasting’ of the bones and three children who demonstrated a variety of severe lesions (e.g. zygomatic bone and rib hypertrophy, porotic hyperostosis, rib lesions, osteopenia and pitted diaphyseal shafts) that are inconsistent with dietary deficiency alone, and more consistent with a diagnosis of genetic anaemia. Two of these children displayed rib lesions typical of those seen in modern cases of thalassaemia. The children of Poundbury Camp represent the first cases of genetic anaemia identified in a British archaeological population. As thalassaemia is a condition strongly linked to Mediterranean communities, the presence of this condition in a child from England, found within a mausoleum, suggests that they were born to wealthy immigrant parents living in this small Roman settlement in Dorset. This paper explores the diagnostic criteria for genetic anaemia in the archaeological literature and what its presence in ancient populations can contribute to our knowledge of past human migration.

Cosmopolitan Catterick? Isotopic evidence for population mobility on Rome’s Northern frontier

In order to investigate how the population diversity at major Romano-British urban centres compared to small towns and military outposts, we conducted multi-isotope (carbon, nitrogen, oxygen and strontium) analyses of bones (42 individuals) and teeth (26 individuals) of human skeletons from Cataractonium/ Roman Catterick in North Yorkshire (U.K.). The results suggest a markedly less diverse population at Catterick than at the larger towns. Significant differences are observed between burials from the town and fort area and the suburb of Bainesse to the south, and it is suggested that these reflect a shift to more localised recruitment for the Roman army in the Late Roman period. Isotope data for the ‘Bainesse Eunuch’, an unusual 4th century burial that has been interpreted as the remains of a ‘transvestite’ priest of Cybele, are not ultimately conclusive but consistent with origins in Southern Britain or areas with a similar climate abroad. This paper also presents strontium isotope data for modern vegetation samples from 17 sites in the Catterick/northern Vale of York area which contribute to a continuing effort to map the biosphere 87Sr/86Sr variation in Britain.

The effect of cleft lip on adults' responses to faces: cross-species findings

Cleft lip and palate is the most common of the congenital conditions affecting the face and cranial bones and is associated with a raised risk of difficulties in infant-caregiver interaction; the reasons for such difficulties are not fully understood. Here, we report two experiments designed to explore how adults respond to infant faces with and without cleft lip, using behavioural measures of attractiveness appraisal (‘liking’) and willingness to work to view or remove the images (‘wanting’). We found that infants with cleft lip were rated as less attractive and were viewed for shorter durations than healthy infants, an effect that was particularly apparent where the cleft lip was severe. Women rated the infant faces as more attractive than men did, but there were no differences in men and women's viewing times of these faces. In a second experiment, we found that the presence of a cleft lip in domestic animals affected adults' ‘liking’ and ‘wanting’ responses in a comparable way to that seen for human infants. Adults' responses were also remarkably similar for images of infants and animals with cleft lip, although no gender difference in attractiveness ratings or viewing times emerged for animals. We suggest that the presence of a cleft lip can substantially change the way in which adults respond to human and animal faces. Furthermore, women may respond in different ways to men when asked to appraise infant attractiveness, despite the fact that men and women ‘want’ to view images of infants for similar durations.

A stress relaxation model for the viscoelastic solids based on the steady-state creep equation

Creep and stress relaxation are inherent mechanical behaviors of viscoelastic materials. It is considered that both are different performances of one identical physical phenomenon. The relationship between the decay stress and time during stress relaxation has been derived from the power law equation of the steady-state creep. The model was used to analyse the stress relaxation curves of various different viscoelastic materials (such as pure polycrystalline ice, polymers, foods, bones, metal, animal tissues, etc.). The calculated results using the theoretical model agree with the experimental data very well. Here we show that the new mathematical formula is not only simple but its parameters have the clear physical meanings. It is suitable to materials with a very broad scope and has a strong predictive ability.
