    This thesis uses phylogenetic methods such as cladistics to address and revaluate the evolution of ceramic data. Evolution is often implied in ceramic studies but its exact operation in relation to cultural transmission is rarely specified. This thesis asks how phylogenetic methods can be used to study ceramic evolution and how these can reform our perception on the narrative of ceramic change. It does this by forming a theoretical approach based on current anthropological and archaeological theories on ceramics, in conjunction with insights from evolutionary methods. A synthesis of ceramic theory tries to outline the different theoretical approaches and how they might fit with evolutionary perceptions of material cultural change. It suggests that the chaîne opératoire of ceramic production is critical in identifying ceramic characteristics to use in evolutionary analysis, and forms the key conceptual framework to address the meaning of ceramic evolution relating to cultural processes. Subsequently the methodology and application of phylogenetic methods is discussed. The following chapter uses a phylogenetic approach based on the general idea of ‘descent with modification from a common ancestor’ to gain insight into the suggested evolution of Tell el-Yahudiya ware in the Eastern Mediterranean. A second case study focusses on the Middle Bronze Age in south-east Arabia and examines the evolution of Wadi Suq vessels, focussing on shapes associated with communal drinking. In the discussion, the results of both areas are brought together and synthesized with a view to evaluating the use and application of phylogenetic methods and their implications for our understanding of ceramic development and what they reflect in terms of the distinct social changes in these regions. Finally, the thesis seeks to evaluate both the use of evolutionary approaches to ceramic change, and the challenges these methods pose to the way archaeologists have traditionally processed ceramic data and analysed ceramic change

    Exposities op een keerpunt

    Often, it is only possible in retrospect to determine whether a particular period or event was a turning point in history. In the conventional historical account of public housing in the Netherlands, the introduction of the National Housing Act in 1902, the Second World War and the end of the post-war reconstruction in the second half of the 1960s are all considered pivotal events. In each of these cases, external incidents were the driving force behind radical accent shifts in policy, in the relationships between people involved and in particular in their orientation towards ambitions, in tasks and working methods. In housebuilding practice, turning points are also often reflected in new design principles emerging for houses and neighbourhoods. This makes the housing stock an easy-to-understand source of information about the societal, economic and sociocultural circumstances in which houses and residential districts came into being. In the 1980s a climate of reorientation in housing policy emerged, with radical consequences for the practice of house-building. As a result of political debate about the future of the housing market, the role of government and the development of housing associations, a new course was set and experiments were carried out in which new opportunities were explored. In this article, I will describe the outdoor exhibitions of the NWR-BouwRAI in 1990 and 1992 with the Muziekwijk and the Filmwijk, two neighbourhoods in Almere, which were much-discussed at the time, as a prelude to a reassessment of the appearance of houses and a reorientation on the then-standard design principles for dwelling floor plans. This architectural revival is perfectly understandable in the context of the policy changes deployed as a response to changing societal and political circumstances.Vaak is pas achteraf vast te stellen of een bepaalde periode of gebeurtenis een keerpunt in de geschiedenis is geweest. In de gangbare geschiedschrijving van de volkshuisvesting in Nederland zijn de invoering van de Woningwet in 1902, de Tweede Wereldoorlog en het einde van de wederopbouwperiode rond de tweede helft van de jaren 1960 keerpunten. Externe gebeurtenissen vormden toen de aanleiding voor radicale accentverschuivingen in het beleid, in onderlinge verhoudingen tussen betrokkenen en vooral in hun oriëntatie op ambities, opgaven en werkwijzen. In de praktijk van de woningbouw zijn keerpunten vaak ook terug te vinden in nieuwe ontwerpprincipes voor woningen en woonbuurten. Dat maakt de woningvoorraad tot een goed te begrijpen bron van informatie over de maatschappelijke, economische en sociaal-culturele omstandigheden waarin woningen en woonbuurten tot stand kwamen. In de jaren 1980 ontstond een klimaat van heroriëntatie in het woningbouwbeleid, met ingrijpende gevolgen voor de praktijk van de woningbouw. Als gevolg van politieke debatten over de toekomst van de woningmarkt, de rol van de overheid en de ontwikkeling van woningcorporaties werden de bakens verzet en experimenten uitgevoerd waarmee nieuwe kansen werden verkend. In dit artikel zal ik de destijds veel besproken buitenexposities van de NWR-BouwRAI in 1990 en 1992 met de Muziekwijk en de Filmwijk in Almere beschrijven als opmaat voor een herwaardering van de uiterlijke verschijningsvorm van woningen en een heroriëntatie op de toen gangbare ontwerpprincipes voor woningplattegronden. Die architectonische revival is goed te begrijpen in de context van de beleidswijzigingen die werden ingezet als reactie op veranderende maatschappelijke en politieke omstandigheden

    An Unusual Case of Hemosiderotic Fibrohistiocytic Lipomatous Lesion: Correlation of MRI and Pathologic Findings

    Get PDF
    The spectrum of lipomatous lesions ranges from benign to highly malignant disease. Differentiation between these lesions is important to indicate prognosis and choose the most appropriate treatment. Hemosiderotic fibrohistiocytic lipomatous lesion (HFLL) is a rare subtype of lipomatous tumor. The diagnosis is usually based on clinical, histological, and immunohistochemical information. Where magnetic resonance (MR) imaging is a suitable modality to assess fatty tumors, no data is reported on MR imaging of HFLL. Here, the MR characteristics are described in correlation with pathologic findings in a case of HFLL in the left thigh, an unusual location

    Delineation of Chondroid Lipoma: An Immunohistochemical and Molecular Biological Analysis

    Aims. Chondroid lipoma (CL) is a benign tumor that mimics a variety of soft tissue tumors and is characterized by translocation t(11;16). Here, we analyze CL and its histological mimics. Methods. CL (n = 4) was compared to a variety of histological mimics (n = 83) for morphological aspects and immunohistochemical features including cyclinD1(CCND1). Using FISH analysis, CCND1 and FUS were investigated as potential translocation partners. Results. All CLs were strongly positive for CCND1. One of 4 myoepitheliomas, CCND1, was positive. In well-differentiated lipomatous tumors and in chondrosarcomas, CCND1 was frequently expressed, but all myxoid liposarcomas were negative. FISH analysis did not give support for direct involvement of CCND1 and FUS as translocation partners. Conclusions. Chondroid lipoma is extremely rare and has several and more prevalent histological mimics. The differential diagnosis of chondroid lipomas can be unraveled using immunohistochemical and molecular support
