Ecological Investigations with the Continuous Plankton Recorder: The Phytoplankton in the Southern North Sea. 1932-37.

1. The changes in the composition and distribution of the plankton of the southern North Sea have been investigated month by month, from June 1932 to December 1937; the present report deals with the phytoplankton. The survey was carried out by the Continuous Plankton Recorder, towed at a standard depth of 10 metres, by ships on regular steamship lines across the North Sea from Hull towards the Skagerrak, to Bremen and to Rotterdam, and later between London and Esbjerg. 2. The material and methods are described, together with a discussion on the validity of this type of survey and some comparison of its results with those obtained by other methods (pp. 76-86). 3. Particular attention has been paid to Rhizosolenia styliformis (pp. 92- 107), Biddulphia sinensis (pp. 108-115), Phaeocystis (pp. 149-153), and the Dinoflagellates (pp. 134-149); of these the first three are known to be of particular importance in relation to the herring fisheries. More generalised data are available for the principal diatoms other than R. styliformis and B. sinensis (pp. 116-134). 4. The main part of the work is an ecological study of the phytoplankton changes in time and space over the 5½ years. Each year is marked by some distinct variations in the abundance and the times of increase, maximum numbers and decline as recorded in the different forms. These variations in the annual cycles are compared on the different lines by a series of graphs arranged against a time scale of months, a set for each year being placed side by side (Plates I-XXI). More detailed studies by more frequent records were made in the autumns of 1934, 1935, 1936 and 1937 (cf. Figs. 3 and 4). The changes in spatial distribution are shown by a series of monthly maps arranged in a similar manner for each year (Plates XXII-LXIV). These intensive studies of the changes in time and space are also intended to form the basis for correlations with other features in the general ecology of the area (e. g. the zooplankton, hydrology, meteorology and fisheries) to be made in later publications. 5. Whilst each form has shown its own peculiar features, a trend towards a general increase in the phytoplankton as a whole has been observed during the period, although the years 1934 and 1936 have in some respects shown deviations and regressive features, and not all organisms have revealed the same trend. The possible relation of this gradual trend to other events observed in recent years in these and neighbouring waters is discussed (pp. 162-167). 6. The application of these results to the study of patchiness (pp. 154-158), inter-relationships in the plankton (pp. 159-160) and to water movements (pp. 160-162) is briefly discussed.

Ecological Investigations with the Continuous Plankton Recorder: The Copepoda of the Southern North Sea. 1932-37.

I. The monthly changes in the distribution and abundance of the Copepoda in the southern North Sea have been investigated from June 1932 to December 1937 by using the Continuous Plankton Recorder. This was towed at a standard depth of 10 metres by ships sailing on regular lines from Hull to Rotterdam, to Bremen and towards the Skagerrak, and later from London to Esbjerg. 2. The methods are described and those limitations which apply more particularly to the Copepoda are discussed (pp. 175 to 186 and 198 to 203). 3. The first part of the report deals with the Copepoda as a whole, i.e. the total population. The difference between the summer and winter distributions is stressed. The variations in numbers from year to year are found to be considerable and it is suggested that they are sufficiently large to be reflected in the success or failure of the broods of those fish which are at some period of their development dependent upon the Copepoda for food. 4. The second part deals with the data concerning the constituent species or groups of allied species ; a list of these is given on p. 197. 5. The group Paracalanus + Pseudocalanus was by far the most abundant and together with the genera Temora and Acartia was found to be responsible for most of the fluctuations in the population (pp. 205 to 208). 6. The distributions, seasonal and spatial, of the other common forms are described, with the exception of that of Oalantts finmarchicus which is to be the subject of a later report. 7. The recorder results are compared with the findings of the International Council survey from 1902 to 1908; some marked disagreements are discussed (pp. 227 to 232). 8. The appearance of the northern forms Oandacia armata and Metridia lucens during the winters of 1932-33, 1933-34 and 1937 are recorded (pp. 222 to 223) 9. A summarised account of the main seasonal changes in the area is given (pp. 232 to 234) and followed by a brief comparison of the 5½ years investigated.

Ecological Investigations with the Continuous Plankton Recorder: The Zooplankton (other than Copepoda and Young Fish) in the Southern North Sea, 1932-37.

I. The report describes the main monthly changes in the distribution and abundance of the zooplankton, other than Copepoda and young fish (dealt with in separate reports), over the southern part of the North Sea from 1932 to 1937. The work is part of the survey carried out by Continuous Plankton Recorders towed at a depth of 10 metres on regular steamship lines between England and the Continent. 2. The limitations to the sampling method are discussed, and it is shown to be unsuitable for recording Mysidacea and Euphausiacea on account of their marked diurnal variation due presumably to vertical migration; they are omitted from the report. 3. The changing distribution of Sagitta, Limacina, Clione, Lamellibranch larvae, Cladocera, Caprellid Amphipoda, Decapod larvae, Echinoderm larvae and Oikopleura are shown in a series of monthly charts while their seasonal fluctuations are compared in time-chart histograms. 4. The Alima larvae of Squilla are recorded on a few occasions in the regions where the Channel opens into the North Sea. 5. The distributional characteristics of the different forms, i.e. their tendencies to even or " patchy " production, are compared.

Presbyterians and science in the north of Ireland before 1874

In his presidential address to the Belfast meeting of the British Association for the Advancement of Science in 1874, John Tyndall launched what David Livingstone has called a ‘frontal assault on teleology and Christian theism’. Using Tyndall's intervention as a starting point, this paper seeks to understand the attitudes of Presbyterians in the north of Ireland to science in the first three-quarters of the nineteenth century. The first section outlines some background, including the attitude of Presbyterians to science in the eighteenth century, the development of educational facilities in Ireland for the training of Presbyterian ministers, and the specific cultural and political circumstances in Ireland that influenced Presbyterian responses to science more generally. The next two sections examine two specific applications by Irish Presbyterians of the term ‘science’: first, the emergence of a distinctive Presbyterian theology of nature and the application of inductive scientific methodology to the study of theology, and second, the Presbyterian conviction that mind had ascendancy over matter which underpinned their commitment to the development of a science of the mind. The final two sections examine, in turn, the relationship between science and an eschatological reading of the signs of the times, and attitudes to Darwinian evolution in the fifteen years between the publication of The Origin of Species in 1859 and Tyndall's speech in 1874.

Joaquim Mir y la tienda de juguetes: microhistoria de un retrato

¿Puede un retrato pictórico suscitar un ejercicio de microhistoria? Nuestra investigación tratará de aportar una respuesta positiva a esta cuestión, analizando para ello uno de los pocos retratos del pintor postimpresionista Joaquim Mir Trinxet, fechado en 1926. El protagonista representado no es otro que el suegro del pintor, Antoni Estalella i Trinxet, un insigne personaje de Vilanova y la Geltrú (Barcelona) que vivió entre dos siglos. La obra está ambientada en la tienda de juguetes de la familia, convirtiéndose así en una de las escasas pinturas que han captado el interior de una juguetería en la España anterior a la Guerra Civil. Gracias a los trabajos de archivo realizados, este artículo reúne diversos documentos inéditos que permiten reconstruir no sólo la vida del retratado, que llegó a ser corresponsal de Francisco Pi y Margall, sino también el ambiente social, artístico y comercial de Vilanova, en un período que abarca desde la década de 1870 a la primera mitad del siglo XX, en plena “Edad de Oro” de la industria juguetera. Es esta una propuesta de metodología historiográfica cuyo recorrido comienza en el oficio arcaico de la tonelería para desembocar al fin en los albores del comercio moderno de juguetes.

O império do professor: a elite ministerial de Salazar, 1932-1944

O colapso da I República Portuguesa (1910-1926) teve lugar durante a vaga de crises dos regimes democráticos europeus do pós-Primeira Guerra Mundial e foi provocado por uma coligação heterogénea de militares e civis conservadores, e não por um movimento fascista (Pinto 2002). Predominantemente republicanos de direita, os generais que dominaram a ditadura militar criada após o golpe de 1926 procuraram o apoio de elementos conservadores e das elites católicas para a criação dos primeiros governos ditatoriais. Não obstante, os militares mantiveram o controlo da maioria das pastas ministeriais e dos cargos da administração local até 1932. Sucessivas crises políticas e financeiras forçaram-nos a negociar com as elites civis vários pactos para a insti tucionalização de um novo regime.

Modeling of in-situ crystallization processes in the Permian mafic layered intrusion of Mont Collon (Dent Blanche nappe, western Alps)

The Mont Collon mafic complex is one of the best preserved examples of the Early Permian magmatism in the Central Alps, related to the intra-continental collapse of the Variscan belt. It mostly consists (> 95 vol.%) of ol+hy-nonnative plagioclase-wehrlites, olivine- and cpx-gabbros with cumulitic structures, crosscut by acid dikes. Pegmatitic gabbros, troctolites and anorthosites outcrop locally. A well-preserved cumulative, sequence is exposed in the Dents de Bertol area (center of intrusion). PT-calculations indicate that this layered magma chamber emplaced at mid-crustal levels at about 0.5 GPa and 1100 degrees C. The Mont Collon cumulitic rocks record little magmatic differentiation, as illustrated by the restricted range of clinopyroxene mg-number (Mg#(cpx)=83-89). Whole-rock incompatible trace-element contents (e.g. Nb, Zr, Ba) vary largely and without correlation with major-element composition. These features are characteristic of an in-situ crystallization process with variable amounts of interstitial liquid L trapped between the cumulus mineral phases. LA-ICPMS measurements show that trace-element distribution in the latter is homogeneous, pointing to subsolidus re-equilibration between crystals and interstitial melts. A quantitative modeling based on Langmuir's in-situ crystallization equation successfully duplicated the REE concentrations in cumulitic minerals of all rock facies of the intrusion. The calculated amounts of interstitial liquid L vary between 0 and 35% for degrees of differentiation F of 0 to 20%, relative to the least evolved facies of the intrusion. L values are well correlated with the modal proportions of interstitial amphibole and whole-rock incompatible trace-element concentrations (e.g. Zr, Nb) of the tested samples. However, the in-situ crystallization model reaches its limitations with rock containing high modal content of REE-bearing minerals (i.e. zircon), such as pegmatitic gabbros. Dikes of anorthositic composition, locally crosscutting the layered lithologies, evidence that the Mont Collon rocks evolved in open system with mixing of intercumulus liquids of different origins and possibly contrasting compositions. The proposed model is not able to resolve these complex open systems, but migrating liquids could be partly responsible for the observed dispersion of points in some correlation diagrams. Absence of significant differentiation with recurrent lithologies in the cumulitic pile of Dents de Bertol points to an efficiently convective magma chamber, with possible periodic replenishment, (c) 2005 Elsevier B.V.

"Ici la Suisse-Do isch t Schwyz-Switzerland calling!" : la société suisse de radiodiffusion (SSR) au service du rayonnement culturel helvetique (1932-1949)

La dialectique entre radiodiffusion et histoire des relations culturelles internationales est un domaine largement inexploré. L'objectif de cette thèse est d'analyser le rôle de la Société suisse de radiodiffusion (SSR), société privée qui exerce jusqu'en 1983 le monopole sur l'ensemble des stations de radio suisses, dans l'intensification des relations culturelles internationales de la Confédération. Pour examiner cette dimension des activités de la SSR, je me suis prioritairement penchée sur l'étude de la radio internationale helvétique, dénommée alors « Service suisse d'ondes courtes » (SOC). A l'instar de plusieurs organismes similaires à l'étranger, le SOC remplit dès ses débuts une double mission : resserrer les liens avec la diaspora et faire rayonner le pays hors des frontières nationales. Cette recherche met sur le devant de la scène un acteur médiatique aujourd'hui totalement oublié, le Service suisse d'ondes courtes. Par rapport à l'historiographie des radios internationales, elle mêle approche institutionnelle et, dans la mesure des sources disponibles, l'analyse de la programmation. Elle complète aussi l'histoire de la diplomatie culturelle suisse en rappelant la place du service public audiovisuel parmi les institutions chargées de promouvoir le pays à l'étranger. Pour finir, cette étude constitue également un apport à l'histoire des organisations internationales liées à la radiodiffusion (UIR, UIT). L'analyse du volet international des activités de la SSR a permis de dépasser la seule notion de « puissance » qui a été jusqu'à ces dernières années au coeur des ouvrages dévolus aux radios internationales. L'objectif poursuivi par la SSR ne réside pas tellement dans la diplomatie d'influence (l'exercice d'un « soft power »), qui tend à imposer ses valeurs et un mode de vie, mais plutôt dans la volonté de faire comprendre et reconnaître la culture politique de la Suisse dans le but de renforcer et pérenniser la place de celle-ci dans le concert des nations. Dans cette perspective, la culture devient un moyen utilisé pour transmettre à l'étranger une représentation valorisante du pays, une image de marque (une forme de « Nation Branding » avant l'heure) également utile au secteur touristique et à l'industrie d'exportation. Le Service suisse d'ondes courtes fait ainsi avant tout des relations publiques, un avant-goût de ce que les Américains appelleront dans les années 1960 la « public diplomacy »
