Early iron production in the Levant: Smelting and smithing at early 1st millennium BC Tell Hammeh, Jordan, and Tel Beth-Shemesh, Israel

The use of iron in the Near East is first attested by the sporadic occurrence of iron artefacts during the Bronze Age. By the end of the Late Bronze Age, however, use of iron metal gradually increases to such a level that one can assume a reasonably regular production of iron metal from terrestrial ores by smelting. However, very few iron metallurgical workshops or installations have been discovered in the Near East thus far. Of these, most are apparently related to secondary smithing, and very few if any have clear evidence for iron smelting. Recent fieldwork at Tell Hammeh, Jordan, identified a major iron smelting operation dated to ca. 930 Cal BC. Excavations in 2001 and 2003 at Tel Beth- Shemesh, Israel, uncovered remains of a full-scale smithing operation, dating to ca. 900 Cal BC. Dedicated excavation techniques were developed and refined for both sites, aiming at optimal recovery of both technological and archaeological information. The excavated materials were comprehensively analysed using relevant scientific analytical techniques, which included the development and application of a calibration method for quantitative bulk chemical analysis of iron- rich materials by XRF. Combining laboratory data and fieldwork, this thesis explores the particular lime- rich and iron-oxide-poor nature of the Hammeh slags as a function of the composition of the local ore and the sacrificial contribution of technical ceramics (tuyeres and furnace wall). Furthermore, it compares the smelting operations at Tell Hammeh with the smithing at Tel Beth-Shemesh, both in terms of their respective archaeological contexts as well as of their technological residues. This aims at the identification and reconstruction of the chaine operatoire of the technologies at both sites. The reconstructed technological processes are discussed in terms of their place in the socio-economic and cultural context of the early first millennium BC of the Levant. Beyond providing new data about early iron metallurgy, the integrated archaeological and laboratory approach, the excavation methods applied, the analytical methodology, as well as the archaeometric data presented here may serve as a model for the excavation, interpretation, or comparison of future (and previous) discoveries of iron metallurgy in the Near East

Improving access to health care for chronic hepatitis B among migrant Chinese populations: a systematic mixed methods review of barriers and enablers.

Migrant Chinese populations in Western countries have a high prevalence of chronic hepatitis B but often experience poor access to healthcare and late diagnosis. This systematic review aimed to identify obstacles and supports to timely and appropriate health service use among these populations. Systematic searches resulted in 48 relevant studies published between 1996 and 2015. Data extraction and synthesis were informed by models of healthcare access that highlight the interplay of patient, provider and health system factors. There was strong consistent evidence of low levels of knowledge among patients and community members; but interventions that were primarily focused on increasing knowledge had only modest positive effects on testing and/or vaccination. There was strong consistent evidence that Chinese migrants tend to misunderstand the need for healthcare for hepatitis B and have low satisfaction with services. Stigma was consistently associated with hepatitis B and there was weak but consistent evidence of stigma acting as a barrier to care. However, available evidence on the effects of providing culturally appropriate services for hepatitis B on increasing uptake is limited. There was strong consistent evidence that health professionals miss opportunities for testing and vaccination. Practitioner education interventions may be important but evidence of effectiveness is limited. A simple prompt in patient records for primary care physicians improved the uptake of testing; and a dedicated service increased targeted vaccination coverage for new-borns. Further development and more rigorous evaluation of more holistic approaches that address patient, provider and system obstacles are needed

Hepatitis B screening in the Turkish-Dutch population in Rotterdam, the Netherlands; qualitative assessment of socio-cultural determinants

Background. Hepatitis B is an important health problem in the Turkish community in the Netherlands. Increased voluntary screening is necessary in this community, to detect individuals eligible for treatment and to prevent further transmission of the disease. Methods. We investigated socio-cultural determinants associated with hepatitis B screening in male and female, first and second generation Turkish migrants, by means of Focus Group Discussions. Results. Socio-cultural themes related to hepatitis B screening were identified; these were social norm, social support, sensitivity regarding sexuality, reputation, responsiveness to authority, religious responsibility, cleanliness and religious doctrine regarding health and disease, and the perceived efficacy of Dutch health care services. Motivating factors were the (religious) responsibility for one's health, the perceived obligation when being invited for screening, and social support to get tested for hepatitis B. Perceived barriers were the association of hepatitis B screening with STDs or sexual activity, the perception of low control over one's health, and the perceived low efficacy of the Dutch health care services. Reputation could act as either a motivator or barrier. Conclusion. This study identified relevant socio-cultural themes related to hepatitis B screening, which may serve to customize interventions aimed at the promotion of voluntary hepatitis B screening in the Turkish-Dutch population in the Netherlands

Decisions set in slag: the human factor in African iron smelting

Slags are the most abundant and best-preserved product of traditional iron smelting and are thus a staple of archaeometallurgical research in this area. A wealth of technical information has been gleaned from these studies, identifying the bloomery process as the universal method of pre-industrial iron production across the Old World. Despite covering such a vast expanse of land and spanning more than two millennia, there is little fundamental variability in the resulting products – bloomery iron and fayalitic slag. This is at odds with the numerous ethnohistorical studies of traditional iron smelting, particularly in Africa, that have documented a bewildering array of practices, both social and technical. This is most spectacularly obvious from the range of furnace designs, from a mere hole in the ground to elaborately decorated and substantial structures kept in semi- permanent use. The social status of smelters within their societies, or associated ritualised practices, are other examples of wide-ranging diversity in iron smelting. Such diversity is not restricted to Africa, but is matched by a similarly wide range of archaeologically documented furnace designs across prehistoric western Asia and Europe. This paper attempts to chart some common ground among the extremes of technical engineering studies, ethnographic documentation and sociopolitical contextualisation in African iron smelting. First by exploring the inherent factors providing the envelope or constraints of technical possibilities, and then identifying degrees of freedom within this envelope which offer room for, or rather require, human decision-taking. Some of these decisions have left their traces in the slag, and teasing out these variables may eventually offer insights into social and cultural practices through technical studies
