The study reviews the Medieval Bulgarian translations from Greek as a multi-centennial process, preconditioned by the constant contacts between Byzantium and its Slavonic neighbor and dependant on the historical and cultural circumstances in Medieval Bulgaria. The facts are discussed from the prospective of two basic determining factors: social and cultural environment (spiritual needs of the age, political and cultural ideology, translationsʼ initiator, centers of translation activities, degree of education/literacy). The chronological and typological analysis of the thematic and genre range of the translated literature enables the outlining of five main stages: (1) Cyrillo-Methodian period (the middle of the 9th centuty – 885) – reception of the corpus needed for missionary purposes; (2) The First Bulgarian Tsardom period (885–1018) – intensive translation activities, founding the Christian literature in Bulgaria; (3) The period of The Byzantine rule (1018–1185) – a standstill in the translation activities and single translations of low-level literature texts; (4) The Second Bulgarian Tsardom – the period of Asenevtsi dynasty (the late 12th and the 13th centuries) – a partial revision of the liturgical and paraliturgical books; (5) The Second Bulgarian Tsardom – the Athonite-Tarnovo period (the 14th – early 15th century) – extensive relations with Byzantium and alignment to the then-current Byzantine models, intensifications of the translations flow and a broad range of the translation stream.

The question of how Constantinople got enough water to support its vast population has been an important area of research. A great deal of valuable work has been done in recent years on the water supply and its technology. Something that has been less thoroughly investigated is the water usage in Constantinople. Once the water was collected in the city, how was it dispersed? How was it used? This paper attempts to trace water distribution, use, and disposal in the city. I will use a combination of literary and material sources to understand the technology of the Constantinopolitan water supply.

The north-eastern escarpment of Madagascar has been labelled a global biodiversity hotspot due to its extremely high rates of endemic species which are heavily threatened by accelerated deforestation rates and landscape change. The traditional practice of shifting cultivation or "tavy" used by the majority of land users in this area to produce subsistence rice is commonly blamed for these threats. A wide range of stakeholders ranging from conservation to development agencies, and from the private to the public sector has therefore been involved in trying to find solutions to protect the remaining forest fragments and to increase agricultural production. Consequently, provisioning, regulating and socio-cultural services of this forest-mosaic landscape are fundamentally altered leading to trade-offs between them and consequently new winners and losers amongst the stakeholders at different scales. However, despite a growing amount of evidence from case studies analysing local changes, the regional dynamics of the landscape and their contribution to such trade-offs remain poorely understood. This study therefore aims at using generalised landscape units as a base for the assessment of multi-level stakeholder claims on ecosystem services to inform negotiation, planning and decision making at a meso-scale. The presented study applies a mixed-method approach combining remote sensing, GIS and socio-economic methods to reveal current landscape dynamics, their change over time and the corresponding ecosystem service trade-offs induced by diverse stakeholder claims on the regional level. In a first step a new regional land cover classification for three points in time (1995, 2005 and 2011) was conducted including agricultural classes characteristic for shifting cultivation systems. Secondly, a novel GIS approach, termed “landscape mosaics approach” originally developed to assess dynamics of shifting cultivation landscapes in Laos was applied. Through this approach generalised landscape mosaics were generated allowing for a better understanding of changes in land use intensities instead of land cover. As a next step we will try to use these landscape units as proxies to map provisioning and regulating ecosystem services throughout the region. Through the overlay with other regional background data such as accessibility and population density and information from a region-wide stakeholder analysis, multiscale trade-offs between different services will be highlighted. The trade-offs observed on the regional scale will then be validated through a socio-economic ground-truthing within selected sites at the local scale. We propose that such meso-scale knowledge is required by all stakeholders involved in decision making towards sustainable development of north-eastern Madagascar.

Four seasons of excavations at Horvat Kur in the Galilee (250570/754485) have exposed the remains of a broadhouse synagogue from the Byzantine period. The building was entered through a portico on the west or a doorway on the south. The fill beneath the portico included the discarded remains of a once colored mosaic as well as more than 1000 coins. A low bench of basalt stones (some of which were plastered) runs along the interior walls, interrupted only by a stone bemah in the center of the southern wall. The synagogue is thus oriented toward Jerusalem. Near the bemah, an ornamented limestone seat was found in situ atop the bench. The building underwent several changes and repairs in the course of its lifespan. On either side of the bemah, north-south rows of columns rested on stylobate. A basalt stone table was found in re-use in the eastern stylobate. Nicknamed “the Horvat Kur stone,” this monolith features geometric figures on three sides and figurative representations on one side. Its original function is as yet subject of research. A narrow test-trench into the sediment of a cistern located outside the northern wall of the synagogue has produced nearly thirty intact vessels of the early Byzantine period, mostly cooking pots and water jars. In addition a dense sequence of pollen samples has been taken. Preliminary interpretation of these finds indicates that the Horvat Kur synagogue illustrates Byzantine synagogue construction, decoration, and use in the setting of a Galilean village of modest economic circumstances.

The paper presents a comparative study of the personal and geographic names in the two complete Slavic translations of the Byzantine Versified Synaxarion, namely the Bulgarian and Serbian Prolog Stišnoj, which appeared around the first half of the 14 th century. On the basis of the March texts in seven South Slavic manuscripts, the differences in the rendering of the personal names are analysed on the level of phonetics, orthography, morphology and word formation. The data allow the following conclusions: 1) The differences in the forms of these names in the Bulgarian and Serbian Prolog Stišnoj give further arguments supporting their independent origin; 2) Several specific tendencies are noted which more or less differentiate them. The Bulgarian translation reproduces more accurately the graphics of the original names, allows dativus possessivus, often replaces the Greek anthroponyms and toponyms with adjectives, presents many local names in the plural, and sometimes retains Greek nominative endings in masculine personal names. The Serbian translation, on the other hand, follows more often the Byzantine pronunciation of the names, complies more strictly with their grammatical characteristics (case, number), separates more often the ending -ς from the stem, and incorporates the accusative ending -ν into the stem of certain anthroponyms several times. 3) The tendency towards Slavicisation of the personal names is nearly the same in both translations and cannot be viewed as peculiar of either of them.

The north-eastern escarpment of Madagascar contains the island’s last remaining large-scale humid forest massifs surrounded by diverse small-scale agricultural mosaics. There is high deforestation mainly caused by shifting cultivation practiced by local land users to produce upland rice for subsistence. Today, large protected areas restrict land users’ access to forests to collect wood and other forest products. Moreover, they are no more able to expand their cultivated land, which leads to shorter shifting cultivation cycles and decreasing plot sizes for irrigated rice and cash crop cultivation. Cash crop production of clove and vanilla is exposed to risks such as extreme inter-annual price fluctuations, pests and cyclones. In the absence of work opportunities, agricultural extension services and micro-finance schemes people are stuck in a poverty trap. New development strategies are needed to mitigate the trade-offs between forest conservation and human well-being. As landscape composition and livelihood strategies vary across the region, these strategies need to be spatially differentiated to avoid implementing generic solutions, which do not fit the local context. However, up to date, little is known about the spatial patterns of shifting cultivation and other land use systems at the regional level. This is mainly due to the high spatial and temporal dynamics inherent to shifting cultivation, which makes it difficult to monitor the dynamics of this land use system with remote sensing methods. Furthermore, knowledge about land users’ livelihood strategies and the risks and opportunities they face stems from very few local case studies. To overcome this challenge, firstly, we used remote sensing data and a landscape mosaic approach to delineate the main landscape types at the regional level. Secondly, we developed a land user typology based on socio-ecological data from household surveys in 45 villages spread throughout the region. Combining the land user typology with the landscape mosaic map allowed us to reveal spatial patterns of the interaction between landscapes and people and to better understand the trade-offs between forest conservation and local wellbeing. While shifting cultivation systems are being transformed into more intensive permanent agricultural systems in many countries around the globe, Madagascar seems to be an exception to this trend. Linking land cover information to human-environmental interactions over large areas is crucial to designing policies and to inform decision making for a more sustainable development of this resource-rich but poverty-prone context.

Purpose To this day, the slit lamp remains the first tool used by an ophthalmologist to examine patient eyes. Imaging of the retina poses, however, a variety of problems, namely a shallow depth of focus, reflections from the optical system, a small field of view and non-uniform illumination. For ophthalmologists, the use of slit lamp images for documentation and analysis purposes, however, remains extremely challenging due to large image artifacts. For this reason, we propose an automatic retinal slit lamp video mosaicking, which enlarges the field of view and reduces amount of noise and reflections, thus enhancing image quality. Methods Our method is composed of three parts: (i) viable content segmentation, (ii) global registration and (iii) image blending. Frame content is segmented using gradient boosting with custom pixel-wise features. Speeded-up robust features are used for finding pair-wise translations between frames with robust random sample consensus estimation and graph-based simultaneous localization and mapping for global bundle adjustment. Foreground-aware blending based on feathering merges video frames into comprehensive mosaics. Results Foreground is segmented successfully with an area under the curve of the receiver operating characteristic curve of 0.9557. Mosaicking results and state-of-the-art methods were compared and rated by ophthalmologists showing a strong preference for a large field of view provided by our method. Conclusions The proposed method for global registration of retinal slit lamp images of the retina into comprehensive mosaics improves over state-of-the-art methods and is preferred qualitatively.

La iconografía mariana ha quedado reflejada en la poesía hispánica medieval de muchas maneras: desde versos que describen a la Virgen y sus atributos hasta conceptos teológicos y mariológicos expresados plásticamente mediante formas retóricas. Por ejemplo, el jardín y las flores como ornamentos y símbolos personales de Santa María, o bien la imagen de la luz a través de un cristal o una ventana de vidrio en escenas de la Anunciación -con abundantes testimonios pictóricos en el arte medieval-, se encuentran en la poesía en forma de descripciones simbólicas de diversa extensión y género y, por otro lado, de advocaciones marianas o tópicos mariológicos (Ave/Eva, Flos, Hortus, Radix-Virga, Regina, Stella). Este artículo propone, pues, un estudio de conjunto y comparativo de algunos de estos procedimientos, concentrándose en las Cantigas de Santa María del rey Alfonso X. En este sentido, las figuras retóricas, como herramientas que tienden un puente entre lo pictórico y lo poético, dirigen necesariamente la lectura hacia una interpretación simbólica proporcionada por la figuración o typologia, tal como la ha postulado Erich Auerbach para la textualidad medieval. En última instancia, el valor sagrado de la imagen mariana (una herencia del arte icónico bizantino) se representa también en los milagros de las Cantigas de Santa María, obra maestra que evidencia una fuerte influencia de la doctrina iconodúlica.

Se argumenta que la arqueología y la historia monetaria reúnen entre sí el potencial para proyectar una imagen de la economía romana muy diferente a la que sugieren los estereotipos minimalistas. Se discuten las implicancias de esta argumentación para el período tardoantiguo en particular, rechazando el catastrofismo con el que Rostovtzeff concluía su célebre historia del temprano imperio. En el imperio tardío la fortaleza de los intereses privados se mantuvo tan firme como siempre, en una economía caracterizada por la integración de los negocios públicos y privados antes que por un supuesto conflicto o antagonismo entre ambos. El imperio de Oriente conservó estas tendencias en forma pura, con niveles sostenidos de comercio y circulación monetaria hasta las décadas centrales del siglo VII. En este trabajo se argumenta que pensar en términos de ciclos económicos sería para los historiadores más razonable que la patología convencional de la "declinación", "decadencia", etc. Este patrón es notablemente evidente en la historia económica bizantina, marcada por abruptas fluctuaciones entre los siglos V y XII.
