Connecting global health interventions and lived experiences: suspending ‘normality’ at funerals in rural Tanzania

In this paper, we use the funeral space and its liminal nature as a milieu for exploring how a ‘modern’ health intervention, the mosquito bednet, is negotiated by its recipients in relation to its (non)-usage in such spaces. With a focus on sleeping arrangements at funerals and drawing on empirical data from participants living in rural southern Tanzania, we discuss how the bednet is linked to the notion of being unsympathetic to the death. Viewed as a symbol of modernity and a reflection of wealth and individual pride, the bednet becomes physically and symbolically inappropriate in the more sacred, ‘in-between’ site of the funeral. We also uncover how risk perceptions regarding malaria transmission are re-cast in funeral spaces, with socio-cultural practices and health-related behaviours being simultaneously ‘risky’ for individual mourners and reinforcing in terms of group social cohesion. As individual mourners' concerns about malaria risks are suspended, notions of pain and discomfort come to the fore as part of the mourning process and respect for the deceased.     

Obsidian from the Epipalaeolithic and Neolithic eastern Maghreb. A view from the Hergla context (Tunisia)

In the present paper, it is shown that in the Hergla area (eastern Tunisia), obsidian was present from the early to at least the late sixth millennium cal BC. The presence of cores indicates that obsidian knapping was at least partly carried out in situ. The origin of these obsidians was determined from their elemental composition, by comparison with those originating from western Mediterranean potential sources, including analyses of new samples from the nearby Pantelleria Island. All obsidians were measured following the same protocol, by particle induced X-ray emission or by scanning electron microscopy/energy dispersion spectrometry. All the Hergla obsidians were found to originate from the Balata dei Turchi sources of Pantelleria. A review of the present body of knowledge on eastern Maghreb suggests, in spite of the still very preliminary data available, that Pantelleria was almost its unique provider of obsidians from the Epipalaeolithic to and during the Neolithic. However, the relative importance of the two main Pantellerian sources of Balata dei Turchi and Lago di Venere as providers of obsidian to eastern Maghreb remains to be investigated.     

The use of SEM-EDS,PIXE and EDXRF for obsidian provenance studies in the Near East: a case study from Neolithic Çatalhöyük (central Anatolia)

In this paper we evaluate the relative analytical capabilities of SEM-EDS, PIXE and EDXRF for characterizing archaeologically significant Anatolian obsidians on the basis of their elemental compositions. The study involves 54 geological samples from various sources, together with an archaeological case study involving 100 artifacts from Neolithic Çatalhöyük (central Anatolia). With each technique the artifacts formed two compositional groups that correlated with the East Göllü Da? and Nenezi Da? sources. The non-destructive capabilities of these methods are emphasized (albeit with certain analytical limitations in the case of SEM-EDS), suggesting important new techniques for Near Eastern obsidian provenance studies.     

昆明市保障性住区居民就业空间特征及其收入效应分析

保障性住房建设解决了大量城市低收入家庭的住房问题,但大多区位偏远、交通不便,远离城市就业中心,导致低收入人群的通勤成本上升,进而对其就业和收入产生影响。本研究以昆明市为样本城市,选取廉租房、公租房和经适房3类保障性住区,利用通勤距离、通勤时间、通勤方式、工作地点等指标,从居住-就业空间匹配角度,揭示保障性住区居民就业空间特征;并通过建立包含空间虚拟变量的多元回归方程,揭示了保障性住区居民就业空间特征对其收入的影响。     

L’impossible constitution d’une théorie générale des machines ?

Three projects on the theories of machines are presented: “mecanology” of the architect Jacques Laffite (1932) inspired by biological evolution; “mecanical analysis ” of Louis Couffignal, a specialist in computing machines (1938), which pre figures functional analysis, and the algebraic theory of machines by the mathematician Jacques Riguet (beginning of the 1950’s). During those years, the three men are members of the Circle of Cybernetic Studies. The article focuses on the dialogue between projects, the axes of unification and divergence, and the styles, strategies and postulates of these three candidates, for generalization converging toward the reference constituted by cybernetics.
