Electrical instruments in 19th century France,between makers and users

Abstract

Having quickly described new historiographical approaches to scientific instruments, this paper explores some characteristics of the evolution of the relationship between scientific instrument makers and French physicists in the 19th century. Artisans without a scientific culture at the dawn of the century, a certain number of instrument makers were integrated into the scientific community by its end, sharing their practices and their values. These builders served as mediators between different physicists, between physicists and members of other disciplines like physiology and, finally, between savants and the world of technology (telegraphy and then industrial electricity). Symmetrically, a significant number of French physicists left mathematical physics for a physics based on instruments and their development. The emergence, extension, and eventual disappearance of the different contexts of use of an instrument (amateurs, public performances, teaching, research, medicine, telegraphy, industry, etc) illustrate both the boundary crossings between these different domains and the major role that use played in successive reconfigurations of instruments.     

Temporal changes in diet: a stable isotope analysis of late Iron Age and Roman Dorset,Britain

This study investigates the relationship between diet and cultural change in late Iron Age and Romano-British populations from Dorset, England (1st century BC to the early 5th century AD). Dorset was the only region in Britain to exhibit continuity in inhumation burial rites through these periods and a wide array of environmental, archaeological and material culture evidence is available there. A sample of N = 77 human adult and N = 17 faunal rib samples were utilized for carbon and nitrogen stable isotope analysis to test the hypothesis that Romanization of the diet would result in greater dietary variation.     

New evidence for jute (<Emphasis Type="Italic">Corchorus capsularis</Emphasis> L.) in the Indus civilization

In this paper, we report the results of an analysis of a preserved structure of jute on a ceramic artifact from the site of Harappa that is dated to 2200–1900 (cal.) BC (Fig. 1). Jute cloth has not previously been identified at this early date in the Indus civilization. Since fiber remains are rare in prehistoric South Asia, we briefly review the evidence for seed and fiber remains used in textile production in this region.     

INTERPRETING SPATIAL ECONOMETRIC ORIGIN‐DESTINATION FLOW MODELS

Spatial interaction or gravity models have been used to model flows that take many forms, for example population migration, commodity flows, traffic flows, all of which reflect movements between origin and destination regions. We focus on how to interpret estimates from spatial autoregressive extensions to the conventional regression‐based gravity models that relax the assumption of independence between flows. These models proposed by LeSage and Pace ( 2008 , 2009 ) define spatial dependence involving flows between regions. We show how to calculate partial derivative expressions for these models that can be used to quantify these various types of effect that arise from changes in the characteristics/explanatory variables of the model.     

‘A good wife stays home’: gendered negotiations over state agricultural programmes,upland Vietnam

Rural and livelihood studies, alongside development organisations, are stressing the importance of gender awareness in debates over food security, food crises and land tenure. Yet, within the Socialist Republic of Vietnam, these gender dynamics are frequently disregarded. In Vietnam, rice is intimately linked to the country's food security. Over the last decade, rice export levels, production methods, and local and global market prices have remained constant preoccupations for governmental and development agencies. Steadfast official approval for agricultural technologies and intensification has seen the domestic growth and importation of hybrid varieties of rice and maize seeds. Yet, the impacts of these technologies on upland ethnic minority rice producers and consumers in Vietnam have been overlooked. For these women and men, such as Hmong and Yao farmers, food security is a daily concern for their near-subsistence livelihoods. While strongly encouraged to grow these new seeds, insufficient research has examined the social realities and experiences of these upland minority groups. Moreover, how such agrarian policies and practices are being implicated in reconfiguring gender roles, relations and identities through transformations to individual and household livelihoods has been ignored. In this article, we focus on the gendered consequences of the government's hybrid rice programme for upland farmers. We reveal recent impacts on family relations, including rising intergenerational tensions across genders, and shifting responsibilities and new negotiations between young spouses. These dynamics are further complicated by household economic status, as household members access specific opportunities available to them to improve everyday food security.     

‘A place to rest’: the role of transitional housing in ending homelessness for women in Calgary,Canada

The purpose of this study was twofold: (1) to determine the role of transitional housing in ending homelessness for women and (2) to explore how gender-specific experiences of homelessness may inform housing service delivery models. Using a participatory research methodology, photovoice, and focus group discussion, nine women with lived experience of homelessness were engaged over 10 weeks in a process of reflection and critical dialogue about their previous experiences in a YWCA transitional housing facility and their current YWCA permanent housing in Calgary, Canada. Through this process women revealed that the key aspects of transitional housing that helped them exit homelessness were the interplay of four important factors: safety, time, a community of women with similar experiences, and a supportive environment with access to appropriate services in which to recover from trauma. Although moving directly from homelessness to permanent housing may be appropriate for some women, findings from this study demonstrate that this may not be the case for all. Our results suggest that once permanently housed women, especially those with histories of trauma, struggle with the trade-off between the rules that kept them safe in transitional housing and living as independent, autonomous adults in the community.     

A Methodology for Assessing the Heritage of Planned Urban Environments: An Australian Study of National Heritage Values

Although urban planning has made strategic and notable contributions to the production of the built environment, these are under‐represented in heritage discourse. Planned environments deserve more attention as a particular class of place because a better understanding of planning and planning excellence can inform best heritage practice. A stepwise methodology for the heritage assessment of planned environments is presented. It is drawn from an Australian study concerned with the identification of places of possible national heritage significance. The approach is constructed around the identification of historical themes (for the categorisation and benchmarking of places based on historical research), indicators (pertaining to the nature of significance in planning terms) and thresholds (pertaining to the degree of significance). The analytical approach is capable of adaptation to diverse settings in which the heritage contribution of planning may be recognised.     

Book Reviews

Heritage is important for the social and cultural health of communities, whilst local stewardship of cultural heritage has the capacity to empower and recover cultural identity. This paper describes a recent project in Lakhnu – a small rural village in Uttar Pradesh, India – to restore a nineteenth century villa formerly used as the village school as an educational facility. In this discussion, we draw attention to the right of groups to manage their culture. The loss of cultural heritage is linked to a loss of identity. We argue that heritage projects have the capacity to empower communities to sustain their heritage and identity and provide useful places for social and material advancement through the concept of a shared ‘symbolic estate’. At Lakhnu, we plan to evoke grass-root conservation where local communities become the rightful stakeholders and decision-makers who are encouraged and facilitated in the realisation of their right to cultural heritage and to stimulate growth and build capacity for the community.     

The cultural biography of a Western Australian war memorial

In common with other western countries, there is resurgence in war commemoration in Australia indicating a serious pursuit of identity and a national story on a collective and personal level. A widespread academic and popular interest in war memory and material culture such as war memorials has emerged. War memorials often find their way on to heritage registers. This paper advances cultural biography as an approach to determine the significance of war memorials arguing that this may give a deeper understanding of its community meaning than present methods. Emerging in archaeology cultural biography considers the way that social interactions between people and objects over time create meaning. Using the Katanning war memorial statue in Western Australia as a case study, this paper argues that a cultural biographical approach may uncover a deeper cultural significance resulting from a focus on relationships than from the traditional focus on the memorial as object.
