'Mamlukisation' between social theory and social practice: an essay on reflexivity, state formation, and the late medieval sultanate of Cairo

This working paper is a reflexive essay that tries to think with and beyond one of the basic assumptions upon which the field of late medieval Syro-Egyptian ‘Mamluk’ studies is built: the idea that all late medieval Syro-Egyptian objects of study are by default first and foremost connected, circumscribed and distinguished by some agency of dominant military slavery, of Mamluk-ness. Acknowledging that there may be different ways to pursue such an epistemological exercise, this essay opts for re-imagining the historical agency of what traditionally tends to be subsumed under the phenomenon of the Mamluk state. It is argued that the notions of state in modern research and of dawla in contemporary texts remain an issue of related analytical confusion. Engaging with this confusion in the generalising fashion of a historical sociology of late medieval Syro-Egyptian political action, this essay proposes an alternative analytical model that is inspired by Michael Chamberlain’s prioritisation of social practices of household reproduction and by Timothy Mitchell’s related understanding of the state as a structural effect of practices of social differentiation. The proposed model sees sultanic political order —the state— as process, in constant flux as the structural effect and structuring embodiment of constantly changing practices of social reproduction, of elite integration and of political distinction, in contexts that range between multipolar and unipolar social organisation at and around Cairo’s court and its military elites. The essay ends with summarily suggesting from this model how the socio-culturally structured and structuring memories of dynastic political order that had remained politically dominant for most of the thirteenth and fourteenth centuries were all but obliterated in the fifteenth century by a new layer of particularly ‘Mamluk’ socio-political meaning

Qalāwūnid discourse, elite communication and the Mamluk cultural matrix: interpreting a 14th-century panegyric

This article analyses a brief panegyric text from mid-14th-century Egypt, authored by the court scribe Ibrāhīm b. al- Qaysarānī (d. 1352) and dedicated to the Qalāwūnid Mamluk sultan al-Malik al-Ṣāliḥ Ismāʿīl (r. 1342-5). It challenges this panegyric’s standard treatment as a work of history and as a product of court propaganda and connects it to wider issues of Mamluk literary production and social organisation. In doing so, a new understanding of this panegyric emerges within a specific context of Mamluk elite communication and social performance, demonstrating at the same time how such a social semiotic reading of Mamluk cultural expressions generates further insights into the symbiotic interactions between Mamluk culture and society

Landings and discards on the pulse trawl MFV "Vertrouwen"TX68 in 2009

The catches in terms of landings and discards were monitored onboard MFV “Vertrouwen” TX68, fishing with two pulse trawls using the Verburg-Holland system during four weeks in June-August 2009. The average fishing speed was about 5 knots. The fishing area of the four trips was east of the coast of England and fishing depth was 36m on average with a minimum depth of 20 m and a maximum depth of 46 m. For this study the standard sampling procedure for the yearly monitoring of discards of conventional beam trawl fleet was applied (van Helmond and van Overzee, 2008). Sampled numbers of fish per haul were raised to numbers and weight per hour, for both. When compared with conventional beam trawls in previous years it seems that with the pulse trawl more sole in number and weights per unit of time was discarded and less plaice was discarded. However, the average discard percentages of as well plaice as sole for the pulse trawl of this study were within range with the average discard percentages of conventional beam trawls in 2005, 2006 and 2007 (van Keeken, 2006; van Helmond and van Overzee, 2007; van Helmond and van Overzee, 2008) . This study gives a general impression of the performance in terms of catches of fishing with a pulse trawl using the Verburg-Holland system. However it is recommended to conduct a comparative study on performance of a beam trawl and a pulse trawl, where the two vessels of similar size fish simultaneously, like was done in 2006 by van Marlen et al. This is to exclude the effects of time and area of fishing

A method for delineation of bone surfaces in photoacoustic computed tomography of the finger

Photoacoustic imaging of interphalangeal peripheral joints is of interest in the context of using the synovial membrane as a surrogate marker of rheumatoid arthritis. Previous work has shown that ultrasound produced by absorption of light at the epidermis reflects on the bone surfaces within the finger. When the reflected signals are backprojected in the region of interest, artifacts are produced, confounding interpretation of the images. In this work, we present an approach where the photoacoustic signals known to originate from the epidermis, are treated as virtual ultrasound transmitters, and a separate reconstruction is performed as in ultrasound reflection imaging. This allows us to identify the bone surfaces. Further, the identification of the joint space is important as this provides a landmark to localize a region-of-interest in seeking the inflamed synovial membrane. The ability to delineate bone surfaces allows us not only to identify the artifacts, but also to identify the interphalangeal joint space without recourse to new US hardware or a new measurement. We test the approach on phantoms and on a healthy human finger

Working Paper 02-10 - The PLANET model - Methodological Report: The Car Stock Module

The vehicle stock module calculates the size and composition of the car stock. Its output is a full description of the car stock in every year, by vehicle type, age and (emission) technology of the vehicle. The vehicle stock is represented in the detail needed to compute transport emissions. The integration of the car stock module in PLANET will allow to better capture the impact of changes in fixed and variable taxes levied on cars. Among these impacts, the effect on the environment is of particular interest.Passenger road transport, Vehicle stock modelling

Een nieuwe geschiedenis van de islamitische wereld : Rijks- en identiteitsvorming in islamitisch West-Azië (7de-18de eeuw)

De wereld die zich uitstrekt tussen de Middellandse Zee en de Centraal-Aziatische steppes, kent van oudsher een rijke en bepalende geschiedenis. Dit was niet anders toen Arabieren in de zevende eeuw, Turken in de elfde eeuw en Mongolen in de dertiende eeuw hier eigen wereld- rijken uitbouwden. Diverse dynamieken van rijks- en identiteitsvorming gingen telkens opnieuw in interactie met de almaar diepere islamitische kleurschakeringen van deze rijke geschiedenis van volkeren en gemeenschappen, en van stedelingen, boeren en nomaden. Een nieuwe geschiedenis van de islamitische wereld beschrijft de twee grote golfbewegingen: de eerste van het zevende-eeuwse Arabië tot het tiende-eeuwse Irak, en de tweede van de elfde-eeuwse steppes in het noordoosten tot de achttiende-eeuwse mediterrane kusten. Telkens wordt er ruim aandacht besteed aan speci eke socio-culturele en politieke verande- ringen, altijd met oog voor historische en globale verbanden en continuïteiten. Op basis van de recentste inzichten in het historisch onderzoek werd zo een geheel nieuwe geschiedenis van deze wereld neergeschreven. Traditionele narratieven die vertellen over uitzonderlijkheid, verstarring en verval, ruimen hier plaats voor meer complexe, omvattende en verbindende contexten. Dit boek is daarom aanbevolen lectuur voor al wie de historische gelaagdheid van de huidige wereld beter - en anders - wenst te begrijpen
