Why does a state build institutional capacity in certain sectors rather than others? Despite having gained leverage explaining the emergence of institutions in the developmental states of East Asia, we have comparatively weak accounts for sub‐national variation in institutional strength, a much more common phenomenon. Investigating the surprising achievements of the Philippines’ National Irrigation Administration, this article advances a theory of sectoral success in the face of a generally poor developmental record. The author demonstrates that executives will only construct institutional capacity when facing strong political pressure combined with resource scarcity. Such vulnerability permits politicians to exercise discretion in choosing which policies to pursue, allowing them to avoid upsetting their coalitions. Once a politician achieves some degree of policy success, he or she is then able to avoid engaging in similar reforms in other fields. Thus we see pockets of institutional capacity in states that otherwise struggle with developmental tasks. 相似文献

Molding maize: the shaping of a crop diversity landscape in the western highlands of Guatemala 总被引:2,自引:0,他引:2
Today's domesticated plants not only embody past human–nature interactions, but also reflect social history. Human seed exchange, replacement and loss are important forces in shaping crop diversity. This essay explores regional history in relation to the shaping of maize diversity in the western highlands of Guatemala. This is an area of exceptional maize heterogeneity and a peripheral part of the region where maize was domesticated. Maize diversity seems to have developed through geographic isolation in networks of seed exchange that were generally very local in scope. However, recent studies on Mexican maize suggest otherwise. However, few studies have examined crop diversity or seed exchange from a historical perspective. A closer examination of regional history suggests which processes might be important for shaping the present geographical distribution of maize diversity. Seeds were occasionally transported over longer distances. As a consequence, maize diversity is geographically not characterised by sharp differences between farming communities; the main differences are to be found in regional occurrences. This challenges antimodern ideas of closed, local native ecologies. Consequently, the conservation of maize genetic resources is a challenge, but not entirely contradictory with its transforming socio-economic context. 相似文献

This essay examines how and why historiography—defined to mean the study of the history of historical writing—first emerged as a legitimate subject of historical inquiry in the United States during the period from 1890 to the 1930s by focusing on the practice of historiography by three of the most influential American historiographers whose work spans this period: J. Franklin Jameson, John Spencer Bassett, and Harry Elmer Barnes. Whereas the development of historiography as a field of study signified a recognition that historians and historical writing are themselves products of the historical process, American historiographers in this period at the same time used historiography to further a scientific ideal of objectivity that was premised on the belief in the ability of historians to separate themselves from that process. Modern scholars (notably, Peter Novick) have attributed to scientific historians like Jameson and Bassett a simplistic and naive positivism; but the ability of these historiographers to recognize the subjective character of historical writing and yet affirm a belief in objectivity reveals that their understanding of historical truth was more complex than modern scholars have acknowledged. In turn, by questioning the belief that the historical profession was originally founded on a naïve faith in the ideal of objective truth, I demonstrate that New Historians like Barnes were more similar to their predecessors, the scientific historians, than they (or later scholars) acknowledged. Thus, rather than portraying the shift from scientific history to the New History as a linear trajectory of development from objectivity to a more relativist viewpoint, I argue that New Historians like Barnes at once expressed a greater recognition than his scientific predecessors of how historical writing was the product of its context, while still insisting on his commitment to an ideal of objectivity that divorced the historian from that context. 相似文献

During the archaeobotanical investigation of Scythian–Sarmatian period (Early Iron Age), pits with crop processing waste, discovered in the floodplain of Donets River, eastern Ukraine, and charred remains of cereal grains, dominated by broomcorn millet, were recorded. The grains from the pits were radiocarbon dated to the fifth to first century BC. Those pits are distant from any known contemporaneous settlement. The apparent disconnection of these pits from any local settlement suggests that (1) millet was brought from other locations by mobile groups, or (2) millet was cultivated locally by populations whose settlements have left no discernible archaeological trace. The analysis of molecular biomarkers preserved in palaeosols that are stratigraphically connected to the pits revealed high levels of miliacin, a molecule that can be preserved in ancient soils and sediments, and that is consistent with broomcorn millet (Panicum miliaceum). High levels in miliacin in soils stratigraphically connected to the pits are interpreted as the result of a large biomass of P. miliaceum produced at time of soil formation. Our biogeochemical results applied to a palaeosol thus attest to the in situ cultivation of crops dominated by the broomcorn millet during the early Iron Age in the floodplain of Donets River. Biochemical examination of soils and palaeosols can thus provide useful information on past dynamics of land-use by ancient population, especially when settlements or macrobotanical remains are absent. 相似文献

Although sickle blades gloss is known to form during the harvest, which is a dynamic process and although it is known to be a type of wear which is the outcome of the repetitive encounters between the sickle blades working edges and plant stems; there is no common way to quantify its intensity. Since there is no consensus over a specific scale that will enable the estimation of the amount of wear, based on the quantification of gloss brightness intensity. In this paper we propose a new measurement system which is based on the projection of laser (He–Ne) beam on glossed sickle blades and an analysis of the reflected images. The results form a relative scale from which it is possible to infer on the sickle blades level of wear, and to create discard models. 相似文献

Pre‐Romanesque murals at Kosto?any pod Tríbe?om, Slovakia, have been investigated by portable X‐ray fluorescence and by microanalytical methods to identify painting materials (pigments and binders), and to explain the degradation of colours. Today, missing green and blue shades have been reconstructed according to residual concentrations of Cu, which correspond to copper chlorides—products of salt corrosion of the copper carbonates azurite and/or malachite, accelerated by micro‐organisms. As confirmed by powder X‐ray microdiffraction, original minium (Pb3O4) has been transformed to brown–black plattnerite (PbO2). In increased humidity, even insoluble pigments are washing down from the walls and the intensity of colours further diminishes. 相似文献

ABSTRACT This article explores the relation between aesthetics and theology in the Book of Job. The overall aim of the article is to explain the relationship between centre and periphery (poetry and prose) and its significance for the theology of the book. The article claims that Job's problem is not the attainment of wisdom but how to reconcile wisdom with suffering—how to relate to suffering. And this theological theme is propagated through aesthetics—including stylistic, narrative, compositional and structural features. It is impossible to point out a preferential reading in the Book of Job because of the fundamental and structural dissonance of the text. This destabilized, ambiguous, paradoxical, ironical and dissonance-producing text is the hermeneutical starting point. Qua dissonance-producing text this feature is used as foundation for the interpretative task. And to get a comprehensive grip on the book two instruments are used: the literary and compositional means are analyzed, and the structural elements are evaluated in their relation between frame and centre. Following this line of interpretation reveals that the stylistic differences of the work manifest crucial theological distinctions. In the book of Job, shape and aesthetics are meaning and theology. 相似文献
