Rushing for Gold: Mobility and Small‐Scale Mining in East Africa

African rural dwellers have faced depressed economic prospects for several decades. Now, in a number of mineral‐rich countries, multiple discoveries of gold and precious stones have attracted large numbers of prospective small‐scale miners. While their ‘rush’ to, and activities within, mining sites are increasingly being noted, there is little analysis of miners' mobility patterns and material outcomes. In this article, on the basis of a sample survey and interviews at two gold‐mining sites in Tanzania, we probe when and why miners leave one site in favour of another. Our findings indicate that movement is often ‘rushed’ but rarely rash. Whereas movement to the first site may be an adventure, movement to subsequent sites is calculated with knowledge of the many risks entailed. Miners spend considerable time at each site before migrating onwards. Those with the highest site mobility tend to be more affluent than the others, suggesting that movement can be rewarding for those willing to ‘try their luck’ with the hard work and social networking demands of mining another site.     

The Green Frog and Desalination: A Nyungar Metaphor for the (Mis‐)Management of Water Resources,Swan Coastal Plain,Western Australia

ABSTRACT In common with Aboriginal groups around Australia, the indigenous people, or Nyungars, of Perth adopt a holistic attitude towards groundwater resources. Of cultural significance are lakes, springs, soaks and watercourses that feature in Dreamtime creation narratives. Perth is experiencing major water shortages and many Nyungars feel that the degradation of the freshwater supply is a result of mismanagement and unsustainable development by non‐Aboriginal people. Proposals for dealing with the issue are seen as equally out of balance with the natural order of things. Water regulators have much to learn from indigenous Australians about water and environmental management. Although water continues to be central to Nyungar identity, the study on which this article is based found evidence of attenuated knowledge about the Dreaming, with discontinuities evident in the way significance is increasingly being read in everyplace rather than in specific ‘story places’.     

Characterisation and blind testing of radiocarbon dating of cremated bone

The success of radiocarbon dating of burned or cremated bones depends on the exposed temperature during burning and the degree of re-crystallisation of the inorganic bone matrix. We present a method for characterisation of likely cremated bones by employing visual inspection, infrared spectrometry and carbon stable isotope analysis on the bio-apatite fraction. The method of radiocarbon dating of cremated bones was tested by dating paired samples of bone and associated context materials such as pitch, charcoal and a dendrochronologically dated oak coffin. The dating of these paired test samples were largely performed as blind tests and showed excellent agreement between pitch and bone. The weighted mean age difference of all test samples is observed to −9 ± 60 ¹⁴C yr. To test the indicators and the effects of the degree of burning, a Late-Neolithic human individual has been studied, as this individual exhibits the full spectrum from low temperature burning (charred) to high temperature (“cremated”) from one end of a single bone to the other. This is reflected as a marked step in numerous parameters as well as in a significant difference in ¹⁴C age between the charred and the cremated bone samples.     

Land use and resource exploitation in the Norse western settlement in Greenland

Undersøgelsen af areal‐ og ressourceudnyttelsen omkring udvalgte mindre, marginalt beliggende nordbogårde i Vesterbygdens centrale del fokuserer især på gårdsanlæggenes vegetationsressourcer med henblik på beregning af deres bæreevne og foderværdi.

På grundlag af biomasseberegninger synes en kronologisk og/eller social betinget bebyggelsesekspansion fra “gode” områder mod mere marginale områder at kunne påvises.

Analyser af forholdet mellem græs‐ og husarealer tyder på, at gårde med begrænset græsareal i nærheden kompenserer herfor enten ved at holde flere får eller geder (fremfor køer), som kræver mindre græs som foder og som oftere huses i fritliggende udhuse, eller ved at have større udhuskapacitet til oplagring af hø høstet længere borte fra gårdene.

En veldokumenter et gård bliver brugt som eksempel til beregning af vegeta‐tionspotentialets bæreevne, det faktiske dyreholds størrelse og husstandens størrelse.

Desuden bliver udnyttelsen af højlandet søgt belyst i forbindelse med betragtninger over forekomsten af anlæg og ressourcer relateret til sæterdrift og rensdyrjagt.     

Lethal differences: a short history of the concepts of wealth and poverty in Danish epidemiological writings, 1858-1914

Through a study of the history of the concepts of wealth and poverty, this paper investigates the onset of a tradition in the conceptual architecture of epidemiological research concerning social differences in mortality rates from 1858 to 1914. It raises the question as to what the concepts of wealth and poverty meant to those who used them and what objects of interventions the conceptual architecture surrounding the concepts enabled the researchers to create. It argues that a transition began in the late 19th century in which an important framework for the understanding of causal relations behind the mortality patterns changed and that this change in turn influenced the scope of what was conceived as relevant objects of intervention.
