The Political and Artistic Program of Prince Petru Rares of Moldavia (1527-1538 and 1541-1546) and the Fresco Series Depicting the “Life of the Mother of God” in the Church of Humor Monastery

En 1993, l’église du monastère Humor et six autres églises du nord de la Moldavie (Roumanie) ont été classifiés comme patrimoine de l'UNESCO, en particulier en raison de leurs caractéristiques iconographiques et architecturales uniques. Construit au seizième siècle, le monastère Humor est devenu un riche centre religieux et culturel sous le patronage du prince Petru Rares de Moldavie. Ce centre a encouragé les innovations architecturales ecclésiales, ainsi qu’un programme très prolifique de fresques, extérieures et intérieures, exprimant une créativité au-delà du canon de la peinture de l'époque. La présente thèse est concentrée sur ces innovations architecturales et iconographiques, comprises à la lumière du contexte historique de ce moment unique dans l'histoire de la Moldavie, dans le siècle qui suivit la chute de Constantinople (1453). Tandis que la première partie de la thèse est concentrée sur ces circonstances historiques, et plus précisément sur l'impact du patronage du Prince Rares, la deuxième partie de la recherche est concentrée sur l'analyse des sources littéraires et de la théologie d’une série unique de fresques, placé dans la gropnita (chambre funéraire) de l’église monastique d’Humor, évoquant la vie de la Mère de Dieu. La série est un exemple extraordinaire d’interaction des textes, le Protévangile de Jacques et le Synaxarion, avec l'iconographie. Une attention particulière à l'iconographie du monastère Humor démontre le besoin de la corrélation entre texte et icône d'une part, ainsi que la nécessité d’une corrélation entre les études théologiques, l'art et l’histoire d’autre part. Un autre avantage de la recherche est de contribuer à une appréciation plus riche des trésors culturels et religieux des communautés chrétiennes de l'Europe de l'Est aux points de vue religieux et culturel, en réponse à leur reconnaissance comme patrimoine de l’UNESCO.

L’école viennoise de contrebasse : genèse et réception

Cette recherche met en parallèle les cultures germanophone et francophone par l’entremise de l’histoire de la contrebasse. La problématique consiste à expliquer l’absence de littérature en français sur l’école viennoise de contrebasse, qui s’est développée dans la seconde moitié du XVIIIe siècle et qui a eu une certaine incidence sur le développement de cet instrument. La première section propose une biographie des principaux représentants de cette école, tous contrebassistes virtuoses actifs à Vienne autour de 1750. Suivent un tour d’horizon des œuvres pour contrebasse concertante du classicisme viennois, puis un rappel historique sur le déclin de cette école. Dans la deuxième section, un parallèle est tracé entre l’avancée du violoncelle et le recul de la contrebasse au XIXe siècle. Suivent une présentation des instruments les plus appréciés de cette époque, à savoir le piano, le cor français et le violoncelle, puis une comparaison entre l’évolution de la contrebasse en France et dans les pays germanophones au XIXe siècle. Finalement, la troisième section est consacrée à la renaissance de l’école viennoise de contrebasse, amorcée au milieu du XXe siècle. Pour observer le déploiement de cette évolution dans les cultures française, germanophone et anglo-saxonne, cette section comporte un examen des œuvres publiées par les maisons d’édition spécialisées en musique ainsi que de celles enregistrées par les contrebassistes.

L'influence caravagesque dans l'art de Jacques-Louis David

Ce mémoire de maîtrise est consacré à un aspect peu étudié de l'art de Jacques-Louis David, c'est-à-dire l'influence caravagesque dans les œuvres de l'artiste. Les différentes périodes de la production de l'artiste sont étudiées en fonction d'identifier cette influence et la façon dont elle s'est manifestée. Cette influence est apparue à partir de la deuxième moitié du 18e siècle dans la peinture française pendant une période de réforme de l'art pictural. Jacques-Louis David n'est pas le seul artiste à s'être intéressé au caravagisme. L'intérêt pour Caravage et ses suiveurs coïncidait aussi avec un intérêt pour le naturalisme et le dessin d'après nature. Le maître de David, Joseph-Marie Vien, a joué un rôle important dans la promotion de ces deux notions. C'est lors de son premier voyage en Italie avec son maître Vien que Jacques-Louis David entra pour la première fois en contact avec le caravagisme. C'est à partir de ce moment que son oeuvre commença à se transformer alors que l'artiste s'affranchit de l'influence de la peinture rococo. Le Salon de 1781 qui suivra ce voyage sera un moment très important dans sa carrière et les œuvres qu'il y présenta étaient grandement marquées par le caravagisme, ce qui se manifeste par la couleur, la lumière et par le rendu naturaliste du corps. Le jumelage entre le naturalisme et l'idéalisme joue un rôle important dans la formation de l'esthétique davidienne. Après ce Salon, l'influence caravagesque s'exprimait de façon moins évidente dans son œuvre, mais elle était toujours présente et se manifestait plutôt par l'emprunt de motifs. Nous avons identifié cette influence jusqu'à la fin de la carrière de l'artiste. Nous voyons aussi dans ce mémoire que le rapport entre David et Caravage peut aussi être effectué par le biais d'une manifestation d'homosexualité et d'androgynie dans le travail des deux artistes. Ce mémoire n'est pas axé sur l'interprétation des œuvres, mais plutôt sur des analyses qui permettent de mettre en évidence l'influence caravagesque

«Oroonoko» d'Aphra Behn en traduction française (1745-2009)

Ce projet offre une analyse des traductions en langue française du roman d’Aphra Behn, Oronooko, or The Royal Slave (1688). Dans cette œuvre, la première femme à vivre de sa plume présente une des premières formulations du discours abolitionniste de la littérature anglaise et met au défi des idées reçues sur l’esclavage depuis le XVIIe siècle. Le texte a été traduit vers le français pour la première fois par Pierre-Antoine de La Place (Behn, 1745), dont l’interprétation s’inscrit dans la tradition des belles infidèles. Sa version connaît un succès fulgurant jusqu’à la fin du XVIIIe siècle, avec de nombreuses rééditions parues entre 1745 et 1799. En 1990, Bernard Dhuicq publie une retraduction dans le but de faire connaître Behn aux lecteurs français du XXe siècle. En 2008, il contribue à la préparation d’une nouvelle édition de La Place, et une réédition de sa propre traduction parue en 1990. Pour sa part, Guillaume Villeneuve adapte le texte au lectorat francophone d’aujourd’hui avec une édition critique comprenant un important appareil critique publiée dans la collection « GF » des Éditions Flammarion en 2009. Les traductions de La Place, d’Dhuicq et de Villeneuve affichent chacune des variations par rapport à l’original, variations qui reflètent l’intention de ces traducteurs et de leurs éditeurs ainsi que les pratiques traductives et éditoriales de leur époque.. Cette étude montre notamment comment le récit de Behn a contribué à changer la conception occidentale de l’esclavage. Elle analyse la réception des propos idéologiques d’Oroonoko dans la culture littéraire et philosophique française, depuis le XVIIIe siècle jusqu’à nos jours. À travers le cas Oronooko, le présent mémoire offre aussi une réflexion d’ordre méthodologique sur l’étude des retraductions dans une perspective historique. L’étude des retraductions vise aujourd’hui des objectifs plus vastes sur le plan historique que ne l’indique l’hypothèse du progrès en retraduction, selon laquelle un texte est retraduit pour être corrigé ou amélioré. Notre travail montre qu’en associant à l’étude des traductions celle de leur paratexte, de leur péritexte et des sujets (traducteurs et éditeurs) qui les produisent, et ce afin de resituer chaque retraduction dans son contexte historique propre, on parvient à faire entrer ces retraductions dans un dialogue interculturel et « transhistoriciste » (Nouss, 2007).

Rights of the Prisoner: An Evolving Jurisprudence

Imprisonment is the most common method of punishment resorted to by almost all legal systems.The new theories of crime causation propounded in the latter half of the nineteenth century gave rise to the feeling that the prisons could be used as appropriate institutions for reforming the offenders. It called for individualisation of punishment.As a result of international movements for humanisation of prisons the judiciary' in tine common law countries started taking active interest in prisoner's treatment.Various studies reveal that much has been done in America to improve the lot of prisoners and to treat them as human beings.The courts there have gone to the extent of saying that there is no iron curtain between a prisoner and the constitution. Most of the rights available to citizens except those which they cannot enjoy due to the conditions of incarceration have also been granted to prisoner.In India also the judiciary has come forward to protect the rights of the prisoners.Maneka Gandhi is a turning point in prisoner's rights.The repeated intervention of courts in prison administration project the view that prisoners have been denied the basic human rights.The High Courts and the Supreme Court of India have been gradually exercising jurisdiction ixl assuming prison justice, including improving the quality of food and amenities, payment of wages and appropriate standards of medical care. Access to courts must be made easier to the aggrieved prisoners.The government should come forward along with some public spirited citizens and voluntary organisations to form a "discharged prisoner“ aid society. The society should exploit opportunities for rehabilitation of prisoners after their release.Most of the prison buildings in the State of Kerala are ill-equipped, ill furnished and without proper ventilation or sanitation and with insufficient water supply arrangements.In India prisoners and prisons today are governed by the old central legislations like Prisons Act l894 Prisoners Act 1900 and the Transfer of Prisoners Act 1950.

Influence of the lateral pterygoid muscle on the growth of the mandibular condilar cartilage

At the end of the last century, a model to explain clinical observations related to the mandibular growth was developed. According to it, the lateral pterigoid muscle (LPM) was one of the main modulators of the differentiation of mesenquimal cells inside the condyle to condroblasts or osteoblasts, and therefore of the growth of the mandibular condilar cartilage (CCM). The main components of the model were the humoral and the mechanical. Nowadays, the humoral would include growth factors such as IGF-I, FGF-2 and VEGF, which seem to be involved in mandibular growth. Since skeletal muscle can secrete these growth factors, there is a possibility that LPM modulates the growth of CCM by a paracrine or endocrine mechanism. The mechanical component derived from the observations that both the blood flow inside the temporomandibular joint (ATM) and the action of the retrodiscal pad on the growth of the CCM, depend, in part, on the contractile activity of the LPM. Despite the fact that there are some results suggesting  hat LPM is activated under conditions of mandibular protrusion, there is no full agreement on whether this can stimulate the growth of CCM. In this review, the contributions and limitations of the works related to mandibular growth are discussed and a model which integrates the available information to explain the role of the LPM in the growth of the CCM is proposed.

Freedom of the Press in Canada and Colombia

A general conclusion of the history of the Canadian press demonstrates that state was built after true journalism had been consolidating. Press development went along with economic progress and this was achievable, in great measure, because of the manner colonization took place in North America. This aided the de facto nationalization of press freedom in Canada. In Colombia, on the contrary, wealth concentration and the Spanish failure to build an economic market, resulted in a constant political instability from the time the Independence War. Legal and the de facto nationalization would be attained only at the end of the twentieth century, though journalism was already part of the institutional arrangement.-----Una conclusión general de la historia de la prensa canadiense demuestra que el estado actual se construyó después de haberse consolidado el verdadero periodismo. El desarrollo de la prensa fue paralelo al progreso económico y se pudo lograr en gran medida por la forma en que se colonizó Norteamérica. Esto ayudó a la nacionalización de facto de la libertad de prensa en Canadá. En Colombia, por el contrario, la concentración de la riqueza y el hecho de que los españoles no construyeran un mercado económico produjeron una inestabilidad política constante desde la época de la Guerra por la Independencia. La nacionalización legal y de hecho solamente se logró a finales del siglo XX, aunque el periodismo ya era parte de la organización institucional. 

Technical education in England, Germany and France in the nineteenth century: a comparison

Este documento describe el desarrollo de la educación técnica en Inglaterra, Alemania y Francia durante el siglo XIX, contrastando sus similaridades y diferencias. También analiza el papel del Estado en la provisión de educación técnica en estos países. El artículo sugiere que el alto estándar científico y técnico en la enseñanza, contribuyó significativamente para que el país se convirtiera en una potencia económica. Por ejemplo, la creciente superioridad técnica de los alemanes sobre los británicos en actividades como producción química, tinturas, hierro y acero, ha sido atribuida al hecho de que los británicos persistieron en el uso de métodos empíricos que representaban una barrera para alcanzar mejoras y adaptación, mientras que los alemanes desarrollaron un sistema de educación universitario y politécnico con fuertes lazos industriales que le permitían convertirse en la potencia industrial mas grande de Europa al inicio del Siglo XX.

Who am I? An identity crisis Identity in the new museologies and the role of the museum professional

Whilst the title of this essay suggests more than one “new museology”, it was rather a licence poétique to emphasize the two major theoretical movements that have evolved in the second half of the 20th Century[1]. As a result of the place(s)/contexts where they originated, and for clarity purposes, they have been labelled in this essay as the “Latin new museology” and the “Anglo-Saxon new museology”; however they both identify themselves by just the name of “New Museology”. Even though they both shared similar ideas on participation and inclusion, the language barriers were probably the cause for many ideas not to be fully shared by both groups. The “Latin New museology” was the outcome of a specific context that started in the 1960s (de Varine 1996); being a product of the “Second Museum Revolution”(1970s)[2], it provided new perceptions of heritage, such as “common heritage”. In 1972 ICOM organized the Santiago Round Table, which advocated for museums to engage with the communities they serve, assigning them a role of “problem solvers” within the community (Primo 1999:66). These ideas lead to the concept of the Integral Museum. The Quebec Declaration in 1984 declared that a museum’s aim should be community development and not only “the preservation of past civilisations’ material artefacts”, followed by the Oaxtepec Declaration that claimed for the relationship between territory-heritage-community to be indissoluble (Primo 1999: 69). Finally, in 1992, the Caracas Declaration argued for the museum to “take the responsibility as a social manager reflecting the community’s interests”(Primo 1999: 71). [1] There have been at least three different applications of the term ( Peter van Mensch cited in Mason: 23) [2] According to Santos Primo, this Second Museum Revolution was the result of the Santiago Round Table in Chile, 1972, and furthered by the 1st New Museology International Workshop (Quebec, 1984), Oaxtepec Meeting (Mexico, 1984) and the Caracas Meeting (Venezuela, 1992) (Santos Primo : 63-64)

Qualitative modelling of sustainable energy scenarios: An application and extension of the Bon Qualitative Input-Output model

Climate change is one of the major challenges facing economic systems at the start of the 21st century. Reducing greenhouse gas emissions will require both restructuring the energy supply system (production) and addressing the efficiency and sufficiency of the social uses of energy (consumption). The energy production system is a complicated supply network of interlinked sectors with 'knock-on' effects throughout the economy. End use energy consumption is governed by complex sets of interdependent cultural, social, psychological and economic variables driven by shifts in consumer preference and technological development trajectories. To date, few models have been developed for exploring alternative joint energy production-consumption systems. The aim of this work is to propose one such model. This is achieved in a methodologically coherent manner through integration of qualitative input-output models of production, with Bayesian belief network models of consumption, at point of final demand. The resulting integrated framework can be applied either (relatively) quickly and qualitatively to explore alternative energy scenarios, or as a fully developed quantitative model to derive or assess specific energy policy options. The qualitative applications are explored here.

An extension of the well-known quaternary section at Godrevy, St Ives Bay, West Cornwall: analysis and review

The well-known Quaternary section at Godrevy, west Cornwall has been often described during the past half century, however, a further section, about a kilometre to the south is considered for the first time since a brief mention at the beginning of the last century. This 200m long exposure rests upon a raised shore platform and consists of a basal raised beach and littoral sand, overlain by a local diamict revealing evidence of post-depositional frost disturbance and finally Holocene dune sand. It is proposed that this Strap Rock site be included within the general discussion of the Godrevy section.

Report of the 2010 assessment of the scientific assessment panel: future ozone and its impact on surface UV

SCIENTIFIC SUMMARY Globally averaged total column ozone has declined over recent decades due to the release of ozone-depleting substances (ODSs) into the atmosphere. Now, as a result of the Montreal Protocol, ozone is expected to recover from the effects of ODSs as ODS abundances decline in the coming decades. However, a number of factors in addition to ODSs have led to and will continue to lead to changes in ozone. Discriminating between the causes of past and projected ozone changes is necessary, not only to identify the progress in ozone recovery from ODSs, but also to evaluate the effectiveness of climate and ozone protection policy options. Factors Affecting Future Ozone and Surface Ultraviolet Radiation • At least for the next few decades, the decline of ODSs is expected to be the major factor affecting the anticipated increase in global total column ozone. However, several factors other than ODS will affect the future evolution of ozone in the stratosphere. These include changes in (i) stratospheric circulation and temperature due to changes in long-lived greenhouse gas (GHG) abundances, (ii) stratospheric aerosol loading, and (iii) source gases of highly reactive stratospheric hydrogen and nitrogen compounds. Factors that amplify the effects of ODSs on ozone (e.g., stratospheric aerosols) will likely decline in importance as ODSs are gradually eliminated from the atmosphere. • Increases in GHG emissions can both positively and negatively affect ozone. Carbon dioxide (CO2)-induced stratospheric cooling elevates middle and upper stratospheric ozone and decreases the time taken for ozone to return to 1980 levels, while projected GHG-induced increases in tropical upwelling decrease ozone in the tropical lower stratosphere and increase ozone in the extratropics. Increases in nitrous oxide (N2O) and methane (CH4) concentrations also directly impact ozone chemistry but the effects are different in different regions. • The Brewer-Dobson circulation (BDC) is projected to strengthen over the 21st century and thereby affect ozone amounts. Climate models consistently predict an acceleration of the BDC or, more specifically, of the upwelling mass flux in the tropical lower stratosphere of around 2% per decade as a consequence of GHG abundance increases. A stronger BDC would decrease the abundance of tropical lower stratospheric ozone, increase poleward transport of ozone, and could reduce the atmospheric lifetimes of long-lived ODSs and other trace gases. While simulations showing faster ascent in the tropical lower stratosphere to date are a robust feature of chemistry-climate models (CCMs), this has not been confirmed by observations and the responsible mechanisms remain unclear. • Substantial ozone losses could occur if stratospheric aerosol loading were to increase in the next few decades, while halogen levels are high. Stratospheric aerosol increases may be caused by sulfur contained in volcanic plumes entering the stratosphere or from human activities. The latter might include attempts to geoengineer the climate system by enhancing the stratospheric aerosol layer. The ozone losses mostly result from enhanced heterogeneous chemistry on stratospheric aerosols. Enhanced aerosol heating within the stratosphere also leads to changes in temperature and circulation that affect ozone. • Surface ultraviolet (UV) levels will not be affected solely by ozone changes but also by the effects of climate change and by air quality change in the troposphere. These tropospheric effects include changes in clouds, tropospheric aerosols, surface reflectivity, and tropospheric sulfur dioxide (SO2) and nitrogen dioxide (NO2). The uncertainties in projections of these factors are large. Projected increases in tropospheric ozone are more certain and may lead to reductions in surface erythemal (“sunburning”) irradiance of up to 10% by 2100. Changes in clouds may lead to decreases or increases in surface erythemal irradiance of up to 15% depending on latitude. Expected Future Changes in Ozone Full ozone recovery from the effects of ODSs and return of ozone to historical levels are not synonymous. In this chapter a key target date is chosen to be 1980, in part to retain the connection to previous Ozone Assessments. Noting, however, that decreases in ozone may have occurred in some regions of the atmosphere prior to 1980, 1960 return dates are also reported. The projections reported on in this chapter are taken from a recent compilation of CCM simulations. The ozone projections, which also form the basis for the UV projections, are limited in their representativeness of possible futures since they mostly come from CCM simulations based on a single GHG emissions scenario (scenario A1B of Emissions Scenarios. A Special Report of Working Group III of the Intergovernmental Panel on Climate Change, Cambridge University Press, 2000) and a single ODS emissions scenario (adjusted A1 of the previous (2006) Ozone Assessment). Throughout this century, the vertical, latitudinal, and seasonal structure of the ozone distribution will be different from what it was in 1980. For this reason, ozone changes in different regions of the atmosphere are considered separately. • The projections of changes in ozone and surface clear-sky UV are broadly consistent with those reported on in the 2006 Assessment. • The capability of making projections and attribution of future ozone changes has been improved since the 2006 Assessment. Use of CCM simulations from an increased number of models extending through the entire period of ozone depletion and recovery from ODSs (1960–2100) as well as sensitivity simulations have allowed more robust projections of long-term changes in the stratosphere and of the relative contributions of ODSs and GHGs to those changes. • Global annually averaged total column ozone is projected to return to 1980 levels before the middle of the century and earlier than when stratospheric halogen loading returns to 1980 levels. CCM projections suggest that this early return is primarily a result of GHG-induced cooling of the upper stratosphere because the effects of circulation changes on tropical and extratropical ozone largely cancel. Global (90°S–90°N) annually averaged total column ozone will likely return to 1980 levels between 2025 and 2040, well before the return of stratospheric halogens to 1980 levels between 2045 and 2060. • Simulated changes in tropical total column ozone from 1960 to 2100 are generally small. The evolution of tropical total column ozone in models depends on the balance between upper stratospheric increases and lower stratospheric decreases. The upper stratospheric increases result from declining ODSs and a slowing of ozone destruction resulting from GHG-induced cooling. Ozone decreases in the lower stratosphere mainly result from an increase in tropical upwelling. From 1960 until around 2000, a general decline is simulated, followed by a gradual increase to values typical of 1980 by midcentury. Thereafter, although total column ozone amounts decline slightly again toward the end of the century, by 2080 they are no longer expected to be affected by ODSs. Confidence in tropical ozone projections is compromised by the fact that simulated decreases in column ozone to date are not supported by observations, suggesting that significant uncertainties remain. • Midlatitude total column ozone is simulated to evolve differently in the two hemispheres. Over northern midlatitudes, annually averaged total column ozone is projected to return to 1980 values between 2015 and 2030, while for southern midlatitudes the return to 1980 values is projected to occur between 2030 and 2040. The more rapid return to 1980 values in northern midlatitudes is linked to a more pronounced strengthening of the poleward transport of ozone due to the effects of increased GHG levels, and effects of Antarctic ozone depletion on southern midlatitudes. By 2100, midlatitude total column ozone is projected to be above 1980 values in both hemispheres. • October-mean Antarctic total column ozone is projected to return to 1980 levels after midcentury, later than in any other region, and yet earlier than when stratospheric halogen loading is projected to return to 1980 levels. The slightly earlier return of ozone to 1980 levels (2045–2060) results primarily from upper stratospheric cooling and resultant increases in ozone. The return of polar halogen loading to 1980 levels (2050–2070) in CCMs is earlier than in empirical models that exclude the effects of GHG-induced changes in circulation. Our confidence in the drivers of changes in Antarctic ozone is higher than for other regions because (i) ODSs exert a strong influence on Antarctic ozone, (ii) the effects of changes in GHG abundances are comparatively small, and (iii) projections of ODS emissions are more certain than those for GHGs. Small Antarctic ozone holes (areas of ozone <220 Dobson units, DU) could persist to the end of the 21st century. • March-mean Arctic total column ozone is projected to return to 1980 levels two to three decades before polar halogen loading returns to 1980 levels, and to exceed 1980 levels thereafter. While CCM simulations project a return to 1980 levels between 2020 and 2035, most models tend not to capture observed low temperatures and thus underestimate present-day Arctic ozone loss such that it is possible that this return date is biased early. Since the strengthening of the Brewer-Dobson circulation through the 21st century leads to increases in springtime Arctic column ozone, by 2100 Arctic ozone is projected to lie well above 1960 levels. Uncertainties in Projections • Conclusions dependent on future GHG levels are less certain than those dependent on future ODS levels since ODS emissions are controlled by the Montreal Protocol. For the six GHG scenarios considered by a few CCMs, the simulated differences in stratospheric column ozone over the second half of the 21st century are largest in the northern midlatitudes and the Arctic, with maximum differences of 20–40 DU between the six scenarios in 2100. • There remain sources of uncertainty in the CCM simulations. These include the use of prescribed ODS mixing ratios instead of emission fluxes as lower boundary conditions, the range of sea surface temperatures and sea ice concentrations, missing tropospheric chemistry, model parameterizations, and model climate sensitivity. • Geoengineering schemes for mitigating climate change by continuous injections of sulfur-containing compounds into the stratosphere, if implemented, would substantially affect stratospheric ozone, particularly in polar regions. Ozone losses observed following large volcanic eruptions support this prediction. However, sporadic volcanic eruptions provide limited analogs to the effects of continuous sulfur emissions. Preliminary model simulations reveal large uncertainties in assessing the effects of continuous sulfur injections. Expected Future Changes in Surface UV. While a number of factors, in addition to ozone, affect surface UV irradiance, the focus in this chapter is on the effects of changes in stratospheric ozone on surface UV. For this reason, clear-sky surface UV irradiance is calculated from ozone projections from CCMs. • Projected increases in midlatitude ozone abundances during the 21st century, in the absence of changes in other factors, in particular clouds, tropospheric aerosols, and air pollutants, will result in decreases in surface UV irradiance. Clear-sky erythemal irradiance is projected to return to 1980 levels on average in 2025 for the northern midlatitudes, and in 2035 for the southern midlatitudes, and to fall well below 1980 values by the second half of the century. However, actual changes in surface UV will be affected by a number of factors other than ozone. • In the absence of changes in other factors, changes in tropical surface UV will be small because changes in tropical total column ozone are projected to be small. By the middle of the 21st century, the model projections suggest surface UV to be slightly higher than in the 1960s, very close to values in 1980, and slightly lower than in 2000. The projected decrease in tropical total column ozone through the latter half of the century will likely result in clear-sky surface UV remaining above 1960 levels. Average UV irradiance is already high in the tropics due to naturally occurring low total ozone columns and high solar elevations. • The magnitude of UV changes in the polar regions is larger than elsewhere because ozone changes in polar regions are larger. For the next decades, surface clear-sky UV irradiance, particularly in the Antarctic, will continue to be higher than in 1980. Future increases in ozone and decreases in clear-sky UV will occur at slower rates than those associated with the ozone decreases and UV increases that occurred before 2000. In Antarctica, surface clear-sky UV is projected to return to 1980 levels between 2040 and 2060, while in the Arctic this is projected to occur between 2020 and 2030. By 2100, October surface clear-sky erythemal irradiance in Antarctica is likely to be between 5% below to 25% above 1960 levels, with considerable uncertainty. This is consistent with multi-model-mean October Antarctic total column ozone not returning to 1960 levels by 2100. In contrast, by 2100, surface clear-sky UV in the Arctic is projected to be 0–10% below 1960 levels.

Sustained monitoring of the Southern Ocean at Drake Passage: past achievements and future priorities

Drake Passage is the narrowest constriction of the Antarctic Circumpolar Current (ACC) in the Southern Ocean, with implications for global ocean circulation and climate. We review the long-term sustained monitoring programmes that have been conducted at Drake Passage, dating back to the early part of the twentieth century. Attention is drawn to numerous breakthroughs that have been made from these programmes, including (a) the first determinations of the complex ACC structure and early quantifications of its transport; (b) realization that the ACC transport is remarkably steady over interannual and longer periods, and a growing understanding of the processes responsible for this; (c) recognition of the role of coupled climate modes in dictating the horizontal transport, and the role of anthropogenic processes in this; (d) understanding of mechanisms driving changes in both the upper and lower limbs of the Southern Ocean overturning circulation, and their impacts. It is argued that monitoring of this passage remains a high priority for oceanographic and climate research, but that strategic improvements could be made concerning how this is conducted. In particular, long-term programmes should concentrate on delivering quantifications of key variables of direct relevance to large-scale environmental issues: in this context, the time-varying overturning circulation is, if anything, even more compelling a target than the ACC flow. Further, there is a need for better international resource-sharing, and improved spatio-temporal coordination of the measurements. If achieved, the improvements in understanding of important climatic issues deriving from Drake Passage monitoring can be sustained into the future.

The ERA-Interim reanalysis: configuration and performance of the data assimilation system

ERA-Interim is the latest global atmospheric reanalysis produced by the European Centre for Medium-Range Weather Forecasts (ECMWF). The ERA-Interim project was conducted in part to prepare for a new atmospheric reanalysis to replace ERA-40, which will extend back to the early part of the twentieth century. This article describes the forecast model, data assimilation method, and input datasets used to produce ERA-Interim, and discusses the performance of the system. Special emphasis is placed on various difficulties encountered in the production of ERA-40, including the representation of the hydrological cycle, the quality of the stratospheric circulation, and the consistency in time of the reanalysed fields. We provide evidence for substantial improvements in each of these aspects. We also identify areas where further work is needed and describe opportunities and objectives for future reanalysis projects at ECMWF

'A theatre of ruins'. Edward Bond & Samuel Beckett: theatrical antagonists

The playwright Edward Bond has long made known his antagonism to dramatists allied to Martin Esslin’s Theatre of the Absurd. The work of Samuel Beckett has come in for particular criticism by Bond. Using published writings (and unpublished correspondence between myself and Bond), I hope to trace the development of this antagonism between ‘Bondian’ and ‘Beckettian’ views of theatre. However, this article will also set out to argue that both early work such as The Pope’s Wedding (1962), and more recent work such as Coffee (1995), make use of motifs, characters and ideas from Beckett’s theatre. The article will set out provisional reasons why Bond, despite his misgivings, is not averse to incorporating elements from Beckett’s ‘theatre of ruins’, as he terms it, into his own work.
