ABSTRACT This paper analyzes the effect of city size and industry size on urban productivity in the food processing industry. Some formulations suggest productivity is associated with industry size rather than city size. However, when allowance is made for the tendency of food processing to locate near relevant raw materials and for regional dummies, there is no support for industry scale economies. Agglomeration effects, associated with city size, do exist. The central estimates are based on the Chan-Mountain version of the translog production function. The results provide information on some facets of the appropriate balance between industrial and agricultural production.  相似文献

Despite boosts in mineral exports, popular post‐conflict minerals‐for‐development reforms in Sierra Leone have failed to significantly reduce poverty. This article uses power as an analytical lens to explore the reasons for this failure, with empirical material from the diamond sector's mining cooperatives scheme (2005), the Diamond Areas Community Development Fund (DACDF), and Kono District. The study shows that there was no significant improvement along four dimensions: material deprivation, education and health, vulnerability, and powerlessness. The authors argue that understanding the impact of these reforms requires a nuanced multi‐scalar examination of power relations, actors, and the social, political, economic and historical context within which mining is embedded. Their findings point to: 1) limits to mineral‐led poverty reduction and the need for realistic expectations and diversification of livelihood opportunities; and 2) the need for interventions that balance power asymmetries and the way that power is exercised among diverse actors, wherein decentralization offers early hope.  相似文献

The article aims to reconsider the history of Ottoman Transjordan during the second half of the nineteenth century. Istanbul's decision to impose its direct control over this province triggered a process of evolution and change within local political spaces. The traditional balance of power was altered and tribes were forced to accept the authority of the Ottoman Empire. States and tribes were not the only political actors. Christian religious institutions also participated in the dynamics of change. The article reconsiders the history of a Christian village of Transjordan, Madaba, to describe the complex relationship between tribes and Christian religious communities during this period of change and evolution. The section Karak highlights the main aspects that characterized the refoundation of Madaba. In the section The Exodus and the Rebirth of Madaba, the exodus of several Christian tribes from Karak to Madaba is analyzed to explain the overlap and intertwinement between the different cultural horizons and sociopolitical logics of the two actors. The section The Village of Madaba analyzes some episodes of daily life in Madaba to detail the consequences of the interaction between tribes and religious communities. Finally, the functioning of the local sociopolitical space on which the Hashemite emirate was later founded is explained. The religious community‐tribe dyad was, in fact, part of the transition from “the tribe to the state.”  相似文献

This essay focuses on a paradigmatic moment in neurobiological studies of invertebrates: the research on the nervous system of cephalopods carried out by Enrico Sereni at the Naples Zoological Station between 1925 and 1931. Although he remained unknown on the historiographic scenario, probably due to his early death, he contributed to Italian science of the first half of the twentieth century. In my paper particular attention will be given to Sereni's study on the pigmentary-effector, neurohumoral, and peripheral nervous systems, since they also accounted for the historical foundation of the experimental vein that, through the years, would lead John Zachary Young, Sereni's follower, to the most well-known discovery of the giant nerve fibers.  相似文献

Several cities in Sweden have been providing book-printing facilities since the 1640s. In our quantitative and explorative analysis of library catalogs from the National Library of Sweden and the National Library of Finland we identify the general trends in publishing, how book-printing has been affected by political events, and how printing developed at different paces in different parts of the realm. We have developed a new method for analyzing the totality of publishing through extensive data harmonization and comprehensive statistical analysis, and by treating library catalogs not as an endpoint of bibliographic research but as an inherently rich source of information. This facilitated the quantitative assessment of printing in the Swedish realm based on the metadata contained in library catalogs. Our data-driven approach to the transformation of public discourse demonstrates that whereas the amount of printed material grew steadily, political ruptures affected the development of printing. We also suggest that the culture of books and printing is best understood through the dynamics of competing intellectual hubs consisting of the university cities and the political center in Stockholm. This perspective further challenges the dominant, nationally delineated approach in book history.  相似文献

The Megalithic Area of Saint‐Martin‐de‐Corléans (Aosta, northern Italy) consists of anthropomorphic stelae dated to the Copper Age and the beginning of the Early Bronze Age. They were carved in different lithologies of varying provenance according to two successive artistic styles, ‘ancient’ and ‘evolved’. A minero‐chemical and a petrographic investigation were carried out on 47 stelae and on reference samples collected from eight different outcrops, aiming to define the provenance of the stone materials. The variety of rocks used for the manufacture of the stelae reflects the geological complexity of the Aosta Valley. Most of the stelae examined were classified as foliated impure marbles, grey banded marbles (‘Bardiglio’), calcschists and metabasites belonging to the Combin Zone (Piedmont Nappe), which outcrops in close proximity to the Megalithic Area. Some stelae of the evolved group consisted of massive marbles with silicate‐bearing layers, attributed to the Sion–Courmayeur Zone. Similar stone materials were reported for the stelae of the same age found at the archaeological area of Petit Chasseur (Sion, Switzerland). This is archaeometric confirmation of the archaeological affinity between the stelae occurring at the two prehistoric sites, supporting the hypothesis of cultural exchanges over the Grand St Bernard Pass since the Early Copper Age.  相似文献

This paper discusses the culinary consumption choices of South Korean international students in Auckland, New Zealand as a route to re-considering the transnational production of familiarity. In particular, this study questions the extent to which culinary consumption by transnational migrants is always an intentional declaration of ‘group loyalties’ or about the re-production of local or national identities. Drawing on research with students this paper illustrates that while some aspects of the familiarity enacted in culinary consumption appear to be ‘local’, in the sense that they are encoded as ‘Korean’, other aspects appear to represent forms of ‘global’ familiarity. Hence, it is argued that culinary consumption in transnational worlds can also more subtly represent an effort to recreate familiarity through reference to characteristics of everyday life before migration that may include what appear to be both global and local products. Such familiarity is then not necessarily about group loyalties or identities but rather an example of the importance of practical know how and familiar sensations in feelings of belonging and attachment.  相似文献
