De episcopis Hispaniarum : agents of continuity in the long fifth century

En année 408 après J.-C., l’Espagne, malgré sa position péninsulaire à la fin de l’Europe, était intégrée à une culture pan-Méditerranéenne qui s’étendait du Portugal jusqu’à la Syrie. Trois décennies n’étaient pas encore passées depuis l’instauration du Christianisme comme religion de l’état romain et l’Eglise Catholique était en pleine croissance. L’année suivante, l’Espagne entra sur une voie de transformation irrémédiable alors que les païens, avec leurs langues barbares Germaniques franchirent les Pyrénées portant la guerre et la misère aux Hispano-Romains et fondant leurs royaumes là où auparavant gouvernait l’état romain. Dans le désarroi du Ve siècle, les évêques Catholiques luttèrent pour imposer leur dominance dans les communautés et dans les coeurs des pieux. À la lumière des progrès dans l’archéologie et la qualité des éditions critiques de nos sources littéraires est venu le moment d’identifier les évêques ibériques avec une attention aux conditions régionales. Ce mémoire caractérise les évêques de l’Espagne et du Portugal et démontre les épreuves auxquelles ils firent face comme intermédiaires entre indigènes et envahisseurs, comme évangélistes parmi les païens, persécuteurs des apostates et gardiens de la romanitas à la fin du monde Antique.

Microphytoplankton community structure in the North Eastern Arabian Sea during Winter Monsoon

The overall attempt of the study was aimed to understand the microphytoplankton community composition and its variations along a highly complex and dynamic marine ecosystem, the northern Arabian Sea. The data generated provides a first of its kind knowledge on the major primary producers of the region. There appears significant response among the microphytoplankton community structure towards the variations in the hydrographic conditions during the winter monsoon period. Interannually, variations were observed within the microphytoplankton community associated with the variability in temperature patterns and the intensity of convective mixing. Changing bloom pattern and dominating species among the phytoplankton community open new frontiers and vistas towards more intense study on the biological responses towards physical processes. The production of large amount of organic matter as a result of intense blooming of Noctiluca as well as diatoms aggregations augment the particulate organic substances in these ecosystem. This definitely influences the carbon dynamics of the northern Arabian Sea. Detailed investigations based on time series as well as trophodynamic studies are necessary to elucidate the carbon flux and associated impacts of winter-spring blooms in NEAS. Arabian sea is considered as one among the hotspot for carbon dynamics and the pioneering records on the major primary producers fuels carbon based export production studies and provides a platform for future research. Moreover upcoming researches based on satellite based remote sensing on productivity patterns utilizes these insitu observations and taxonomic data sets of phytoplankton for validation of bloom specific algorithm development and its implementation. Furthermore Saurashtra coast is considered as a major fishing zone of Indian EEZ. The studies on the phytoplankton in these regions provide valuable raw data for fishery prediction models and identifying fishing zones. With the Summary and Conclusion 177 baseline data obtained further trophodynamic studies can be initiated in the complex productive North Eastern Arabian Seas (NEAS) ecosystem that is still remaining unexplored.

A Comparative Study on Internationalization and the Role of International Offices at Selected Middle Eastern and German Universities

Internationalization of higher education has become one of the most important policies for institutions of higher education worldwide. Though universities are international by nature, the need for intensified quality activities of international nature has promoted internationalization to be under spotlight of researchers, administrators and policy makers and to be an area for research. Each institution follows its certain way to govern its international affairs. Most Universities, especially in the 'Developed World' started to plan it strategically. This study explores the meanings and importance of internationalization especially that it means different things to different people. It also studies the rationales behind internationalizing higher education. It focuses on the four main prevailing rationales; political, cultural/social, economic/financial, and academic on both national and institutional levels. With the increasing need to strategically plan, the study explores internationalization strategies in terms of how to develop them, what are their approaches and types, and their components and dimensions. Damascus University has witnessed an overwhelming development of its international relations and activities. Therefore, it started to face a problem of how to deal with this increasing load especially that its International Office is the only unit that deals with the international issues. In order to study the internationalization phenomenon at Damascus University, the 2WH approach, which asks the what, why, and how questions, is used and in order to define the International Office's role in the internationalization process of the University, it studies it and the international offices of Kassel University, and Humboldt University in Germany, The University of Jordan, and Al Baath University in Syria using the 'SOCIAL' approach that studies and analyses the situation, organization, challenges, involvement, ambitions, and limitations of these offices. The internationalization process at the above-mentioned Universities is studied and compared in terms of its meaning, rationales for both the institution and its academic staff, challenges and strategic planning. Then a comparison is made among the international offices of the Universities to identify their approaches, what led to their success and what led to their failure in their practices. The aim is to provide Damascus University and its International Office with some good practices and, depending on the experiences of the professionals of the case-studies, a suggested guidance to the work of this Office and the University in general is given. The study uses the interviews with the different officials and stakeholders of the case-studies as the main method of collecting the information in addition to site visits, studying their official documents and their websites. The study belongs to qualitative research that has an action dimension in it since the recommendations will be applied in the International Office. The study concludes with few learned lessons for Damascus University and its International Office depending on the comparison that was done according to a set of dimensions. Finally a reflection on the relationship between internationalization of higher education and politics, the impact of politics on Middle Eastern Universities, and institutional internationalization strategies are presented.

La situación de los refugiados palestinos en el Líbano a partir del Acuerdo de Taif en la década de los 90.

El interés de esta monografía es analizar la situación en la que viven los refugiados palestinos en el Líbano a partir de las políticas impuestas por el gobierno desde la década de los 90. Se analiza y explica cómo un Estado con el fin de defender su seguridad nacional se convierte en una fuente de amenazas para la seguridad humana de ciertos individuos. A través de la perspectiva de Barry Buzan se busca explicar el proceso de securitización por medio del cual los refugiados palestinos son vistos como una amenaza existencial para la seguridad nacional libanesa.

Evaluating the Small Population Paradigm for Rare Large-Bodied Woodpeckers, with Implications for the Ivory-billed Woodpecker

Six large-bodied, ≥ 120 g, woodpecker species are listed as near-threatened to critically endangered by the International Union for Conservation of Nature (IUCN). The small population paradigm assumes that these populations are likely to become extinct without an increase in numbers, but the combined influences of initial population size and demographic rates, i.e., annual adult survival and fecundity, may drive population persistence for these species. We applied a stochastic, stage-based single-population model to available demographic rates for Dryocopus and Campephilus woodpeckers. In particular, we determined the change in predicted extinction rate, i.e., proportion of simulated populations that went extinct within 100 yr, to concomitant changes in six input parameters. To our knowledge, this is the first study to evaluate the combined importance of initial population size and demographic rates for the persistence of large-bodied woodpeckers. Under a worse-case scenario, the median time to extinction was 7 yr (range: 1–32). Across the combinations of other input values, increasing initial population size by one female induced, on average, 0.4%–3.2% (range: 0%–28%) reduction in extinction rate. Increasing initial population size from 5–30 resulted in extinction rates < 0.05 under limited conditions: (1) all input values were intermediate, or (2) Allee effect present and annual adult survival ≥ 0.8. Based on our model, these species can persist as rare, as few as five females, and thus difficult-to-detect, populations provided they maintain ≥ 1.1 recruited females annually per adult female and an annual adult survival rate ≥ 0.8. Athough a demographic-based population viability analysis (PVA) is useful to predict how extinction rate changes across scenarios for life-history attributes, the next step for modeling these populations should incorporate more easily acquired data on changes in patch occupancy to make predictions about patch colonization and extinction rates.

The Influence of Summer Climate on Avian Community Composition in the Eastern Boreal Forest of Canada

Understanding the relative influence of environmental variables, especially climate, in driving variation in species diversity is becoming increasingly important for the conservation of biodiversity. The objective of this study was to determine to what extent climate can explain the structure and diversity of forest bird communities by sampling bird abundance in homogenous mature spruce stands in the boreal forest of the Québec-Labrador peninsula using variance partitioning techniques. We also quantified the relationship among two climatic gradients, summer temperature and precipitation, and bird species richness, migratory strategy, and spring arrival phenology. For the bird community, climate factors appear to be most important in explaining species distribution and abundance because nearly 15% of the variation in the distribution of the 44 breeding birds selected for the analysis can be explained by climate. The vegetation variables we selected were responsible for a much smaller amount of the explained variation (4%). Breeding season temperature seems to be more important than precipitation in driving variation in bird species diversity at the scale of our analysis. Partial correlation analysis indicated that bird species richness distribution was determined by the temperature gradient, because the number of species increased with increasing breeding season temperature. Similar results were observed between breeding season temperature and the number of residents, short-distance and long-distance migrants, and early and late spring migrants. Our results suggest that the northern and southern range boundaries of species are not equally sensitive to the temperature gradient across the region.

Evaluating the efficacy of planktonic foraminifer calcite and 18O data for sea surface temperature reconstruction for the Late Miocene

This study examines the efficacy of published δ18O data from the calcite of Late Miocene surface dwelling planktonic foraminifer shells, for sea surface temperature estimates for the pre-Quaternary. The data are from 33 Late Miocene (Messinian) marine sites from a modern latitudinal gradient of 64°N to 48°S. They give estimates of SSTs in the tropics/subtropics (to 30°N and S) that are mostly cooler than present. Possible causes of this temperature discrepancy are ecological factors (e.g. calcification of shells at levels below the ocean mixed layer), taphonomic effects (e.g. diagenesis or dissolution), inaccurate estimation of Late Miocene seawater oxygen isotope composition, or a real Late Miocene cool climate. The scale of apparent cooling in the tropics suggests that the SST signal of the foraminifer calcite has been reset, at least in part, by early diagenetic calcite with higher δ18O, formed in the foraminifer shells in cool sea bottom pore waters, probably coupled with the effects of calcite formed below the mixed layer during the life of the foraminifera. This hypothesis is supported by the markedly cooler SST estimates from low latitudes—in some cases more than 9 °C cooler than present—where the gradients of temperature and the δ18O composition of seawater between sea surface and sea bottom are most marked, and where ocean surface stratification is high. At higher latitudes, particularly N and S of 30°, the temperature signal is still cooler, though maximum temperature estimates overlap with modern SSTs N and S of 40°. Comparison of SST estimates for the Late Miocene from alkenone unsaturation analysis from the eastern tropical Atlantic at Ocean Drilling Program (ODP) Site 958—which suggest a warmer sea surface by 2–4 °C, with estimates from oxygen isotopes at Deep Sea Drilling Project (DSDP) Site 366 and ODP Site 959, indicating cooler than present SSTs, also suggest a significant impact on the δ18O signal. Nevertheless, much of the original SST variation is clearly preserved in the primary calcite formed in the mixed layer, and records secular and temporal oceanographic changes at the sea surface, such as movement of the Antarctic Polar Front in the Southern Ocean. Cooler SSTs in the tropics and sub-tropics are also consistent with the Late Miocene latitude reduction in the coral reef belt and with interrupted reef growth on the Queensland Plateau of eastern Australia, though it is not possible to quantify absolute SSTs with the existing oxygen isotope data. Reconstruction of an accurate global SST dataset for Neogene time-slices from the existing published DSDP/ODP isotope data, for use in general circulation models, may require a detailed re-assessment of taphonomy at many sites.

'Roman' or 'native' bodies in Britain: the evidence of late Roman nail-cleaner strap-ends

This paper reviews late Roman `nail-cleaner strap-ends', a group of objects first discussed by Hawkes and Dunning (1961). The precise function of these objects is unclear as their shape suggests use as toilet instruments but the split socket suggests that they were part of belt-fittings. We suggest a detailed typology and discuss the dating evidence and the spatial distribution of the type. Regardless of their precise function, it is argued in this paper that nail-cleaner strap-ends of this type are unique to late Roman Britain and thus represent a distinct regional type. The use of nail-cleaner strap-ends can be viewed in the context of gender associations, military status and religious beliefs.

Magic for the dead? The archaeology of magic in later medieval burials

THIS PAPER EXAMINES patterns in the placement of apotropaic objects and materials in high- to late-medieval burials in Britain (11th to 15th centuries). It develops an interdisciplinary classification to identify: (1) healing charms and protective amulets; (2) objects perceived to have occult natural power; (3) 'antique' items that were treated as possessing occult power; and (4) rare practices that may have been associated with the demonic magic of divination or sorcery. Making comparisons with amulets deposited in conversion-period graves of the 7th to 9th centuries it is argued that the placement of amulets with the dead was strategic to Christian belief, intended to transform or protect the corpse. The conclusion is that material traces of magic in later medieval graves have a connection to folk magic, performed by women in the care of their families, and drawing on knowledge of earlier traditions. This popular magic was integrated with Christian concerns and tolerated by local clergy, and was perhaps meant to heal or reconstitute the corpse, to ensure its reanimation on judgement day, and to protect the vulnerable dead on their journey through purgatory.

A review of palaeoclimates and palaeoenvironments in the Levant and Eastern Mediterranean from 25,000 to 5000 years BP: setting the environmental background for the evolution of human civilisation

The southern Levant has a long history of human habitation and it has been previously suggested that climatic changes during the Late Pleistocene-Holocene stimulated changes in human behaviour and society. In order to evaluate such linkages, it is necessary to have a detailed understanding of the climate record. We have conducted an extensive and up-to-date review of terrestrial and marine climatic conditions in the Levant and Eastern Mediterranean during the last 25,000 years. We firstly present data from general circulation models (GCMs) simulating the climate for the last glacial maximum (LGM), and evaluate the output of the model by reference to geological climate proxy data. We consider the types of climate data available from different environments and proxies and then present the spatial climatic "picture" for key climatic events. This exercise suggests that the major Northern Hemisphere climatic fluctuations of the last 25,000 years are recorded in the Eastern Mediterranean and Levantine region. However, this review also highlights problems and inadequacies with the existing data. (c) 2006 Elsevier Ltd. All rights reserved.

Why the western Pacific subtropical high has extended westward since the late 1970s

The western Pacific subtropical high (WPSH) is closely related to Asian climate. Previous examination of changes in the WPSH found a westward extension since the late 1970s, which has contributed to the inter-decadal transition of East Asian climate. The reason for the westward extension is unknown, however. The present study suggests that this significant change of WPSH is partly due to the atmosphere's response to the observed Indian Ocean-western Pacific (IWP) warming. Coordinated by a European Union's Sixth Framework Programme, Understanding the Dynamics of the Coupled Climate System (DYNAMITE), five AGCMs were forced by identical idealized sea surface temperature patterns representative of the IWP warming and cooling. The results of these numerical experiments suggest that the negative heating in the central and eastern tropical Pacific and increased convective heating in the equatorial Indian Ocean/ Maritime Continent associated with IWP warming are in favor of the westward extension of WPSH. The SST changes in IWP influences the Walker circulation, with a subsequent reduction of convections in the tropical central and eastern Pacific, which then forces an ENSO/Gill-type response that modulates the WPSH. The monsoon diabatic heating mechanism proposed by Rodwell and Hoskins plays a secondary reinforcing role in the westward extension of WPSH. The low-level equatorial flank of WPSH is interpreted as a Kelvin response to monsoon condensational heating, while the intensified poleward flow along the western flank of WPSH is in accord with Sverdrup vorticity balance. The IWP warming has led to an expansion of the South Asian high in the upper troposphere, as seen in the reanalysis.
