Flexural Behavior of Typical Chinese Traditional Timber Stitching Beams

In Chinese traditional timber buildings, stitching is very common. When the bearing capacity or the rigidity is inadequate, a timber beam is often strengthened with another beam using the stitching method. The timber stitching beams are mainly of two types—the small-top/big-bottom type and the big-top/small-bottom type. To study the bending behavior of these two types of timber stitching beams, including the failure mode, the flexural capacity, the strain distribution at mid-span section, and the maximum deflection, bending tests are carried out on 14 timber stitching beams with Chinese traditional conformation for seven pine beams and seven fir beams. The results show that the failure modes of the small-top/big-bottom type of stitching beams all show brittle fractures at the bottoms of the bottom beams. The failure modes of the big-top/small-bottom type of stitching beams all show brittle fractures at the bottoms of the top beams. The distribution of section strain along the height of each part of the beam basically obeys plane hypothesis. Based on the theoretical and experimental analysis, the calculation formulas of flexural capacity and maximum deflection of these two types of timber stitching beams made of pine and fir are presented.     

Luxemburg on Tahrir Square: Reading the Arab Revolutions with Rosa Luxemburg's The Mass Strike

The protests on Tahrir Square in Cairo have come to symbolize the Arab uprisings of 2011. They have proven that Arab political life is more complex than the false choice between authoritarian rule or Islamist oppositions. The popular uprisings witnessed the emergence of “the Arab peoples” as political actors, able to topple entrenched authoritarian leaders, challenging repressive regimes and their brutal security apparatuses. In our contribution we want to analyze the political dynamics of these uprisings beyond the salient immediacy of the revolutionary events, by taking, as our guide, Rosa Luxemburg's pamphlet The Mass Strike (2005 [1906], London: Bookmarks). An interesting theoretical contribution to the study of revolution, Luxemburg's book provides us with tools to introduce a historical and political reading of the Arab Spring. Based on fieldwork and thorough knowledge of the region, we draw from evidence from the Tunisian and Egyptian revolutions and the more gradual forms of political change in Morocco. Re‐reading the revolutionary events in Tunisia, Egypt and Morocco through the lens of The Mass Strike offers activists on the ground insights into the dialectic between local and national struggles, economic and political demands, strike actions and revolution. The workers protests in Tunisia and Egypt during the last decade can be grasped as anticipations of the mass strike during the revolution; the specific mode in which workers participate as a class in the revolutionary process. This perspective enables an understanding of the current economic conflicts as logical forms of continuity of the revolution. The economic and the political, the local and the national (and one may add the global), are indissoluble yet separate elements of the same process, and the challenge for revolutionary actors in Tunisia and Egypt lies in the connection, organization and fusion of these dispersed moments and spaces of struggle into a politicized whole. Conversely, an understanding of the reciprocity between revolutionary change and the mass strike allows activists in Morocco to recognize the workers' movement as a potentially powerful actor of change, and trade unionists to incorporate the political in their economic mobilizations.     

The Problem of Slums: Shifting Methods of Neoliberal Urban Government in Morocco

This article puts forward two main arguments. First, it highlights the relationship between different phases of neoliberalism in Morocco together with the specific methods and techniques of urban government that were deployed in an effort to govern the slums and their populations. A period of ‘roll back neoliberalism’ during the 1980s generated reforms that tried to increase government control over the urban territory to compensate for the negative social outcomes of structural adjustment. The subsequent period of ‘roll out neoliberalism’ coincided with the attempt to manage and regulate the slum population through new modalities of state intervention. Second, while evolutions in neoliberal government reflected a gradual process, this transition in Morocco was accelerated by security concerns following two moments of serious urban violence: the 1981 riots and the 2003 suicide bombings in Casablanca. Therefore, Morocco's recent political transformations cannot be understood in terms provided by the mainstream narrative linking economic liberalization to democratization. Rather, they reflect a profound shift towards intrinsically authoritarian modalities of neoliberal government which are clearly revealed at the urban scale.     

Botta Adorno,Empress Maria Theresa and Brussels Tapestry in the Mid-Eighteenth Century. Part I

Relying on newly excavated archival sources, this two-part study seeks to map the genesis and development of the plan conceived by Antoniotto di Botta Adorno (1688–1774), Minister Plenipotentiary of the Austrian Netherlands from 1749 to 1753, to support the Brussels tapestry industry by promoting Brussels tapestries as diplomatic gifts. The first part sheds fresh light on the lives and mutual relations between the tapestry producers (tapissiers) who populated the landscape in the 1750s — Peter van den Hecke (1680–1752), Daniel IV Leyniers (1705–1770) and the half-brothers Jan Frans (1697–1774) and Peter II van der Borcht (1712–1760) — and analyses the slow maturation of Adorno’s plan in the summer of 1749. The second article will describe the way in which Botta Adorno made the project a reality and will also examine the strategies devised by the Minister and the Brussels tapissiers and the context in which they sought to apply them.     

Claiming Commerce,Quality and Credit: Raisons d’être of the Antwerp and Brussels tapissierspanden (Sixteenth–Eighteenth Centuries)

Literature on the Antwerp and Brussels tapissierspanden tends to give a one-dimensional account of the institutions as very similar commercial enterprises that were embraced wholeheartedly by everyone involved in the Antwerp and Brussels tapestry worlds since they all shared the same concerns and a single goal — namely, to develop and secure a central meeting point and marketplace. This essay, however, adopts a different vantage point. It discusses the tapissierspanden from the viewpoint of the conflicting business conduct and strategies developed by Antwerp city council and tapestry entrepreneurs on the one hand, and Brussels tapestry entrepreneurs on the other. This essay argues that those who founded the institutions in Antwerp and Brussels established and used them to further completely different objectives — and that their strategies, which both manifested themselves and crystallised in the panden, present tapestry scholarship with a fundamental methodological problem, the magnitude of which has yet to be appreciated.     

Flexural Performance of Small Fir and Pine Timber Beams Strengthened With Near-Surface Mounted Carbon-Fiber-Reinforced Polymer (NSM CFRP) Plates and Rods

In order to study the flexural performance of fir and pine timber beams strengthened with near-surface mounted carbon-fiber-reinforced polymer (CFRP) plates and rods, bending tests on 20 specimens are carried out, including four unstrengthened specimens, four specimens strengthened with CFRP plate with the dimension of 1.4 mm × 30 mm, four specimens strengthened with CFRP plate with the dimension of 2.8 mm × 30 mm, four specimens strengthened with one Φ6 mm CFRP rod, and four specimens strengthened with one Φ8 mm CFRP rod. The proportions of fir specimens and pine specimens are 50% and 50%. The results show that compared with the unstrengthened specimens, there is an improvement in flexural capacity and stiffness of the specimens strengthened with near-surface mounted CFRP plates and rods respectively. Finally, the calculation formulas of the flexural capacity of fir and pine timber beams strengthened with near-surface mounted CFRP plates and rods are presented.     

Military and Maritime Evidence of Pandemic Influenza in Canada during the Summer of 1918

Analysis of archival correspondence, the daily logs of troopships transporting soldiers to Europe and the Commonwealth War Graves Commission database for soldier deaths from pneumonia and influenza across Canada indicate that influenza was more common during the summer of 1918 than previously thought. Evidence of pandemic influenza so close to the outbreak of the fall wave calls into question the storyline of a mutated virus causing the emergence of the fall wave of the 1918 influenza pandemic. This highlights the significance of other host, social and environmental circumstances, many related to the First world war, that may have contributed to the severity and timing of pandemic waves in Canada.     

Divorce and social class during the early stages of the divorce revolution: evidence from Flanders and the Netherlands

In times of low divorce rates (such as the nineteenth century and early twentieth century), the authors expect higher social strata to have the highest divorce chances as they are better equipped to break existing barriers to divorce. In this article, the authors analyze data from marriage certificates to assess whether there was a positive effect of occupational class on divorce in Belgium (Flanders) and the Netherlands. Their results for the Netherlands show a positive association between social class and divorce, particularly among the higher cultural groups. In Flanders, the authors do not find this, but they observe a negative association between illiteracy and divorce, an observation pointing in the same direction.
