Developing geographic information infrastructures for local government: the role of trust

The United States's National Spatial Data Infrastructure (NSDI) model presumes that the local government agencies of counties and municipalities will share their geographic information freely with government agencies of regions, states and federal agencies. This article takes up the issue of local government involvement in the NSDI by asking the question: why should local governments involve themselves in the NSDI? This question is informed by considering the social and technological imbrication of the NSDI. One of the oldest spatial data infrastructure projects, the NSDI offers insights into the complexity of implementing infrastructure in federal models of shared governance. This article focuses on the political and financial dimensions of developing infrastructure among local governments. Trust is quintessential at this level of government. Local government agency activities experience an inherently closer coupling with political representatives and with different agencies in both intramunicipal and intermunicipal activities. Building the NSDI is fundamentally an interagency act and thus a matter of trust. Trust is a key issue in the development of the NSDI, as the results of a study of Kentucky local government agencies indicate.     

Targeting Research for Poverty Reduction in Marginal Areas of Rural Syria

Agricultural research in marginal dry areas can contribute to reducing poverty through the development of technological, institutional and policy options for poor farmers. Such research should address diversified opportunities and development pathways. This article analyses the diversity of livelihood strategies of rural people living in the Khanasser Valley in northwestern Syria, an area that is typical of marginal drylands. It proposes an operational classification of households based on their different livelihood strategies, applying an integrated methodology within a Sustainable Livelihoods framework. Households are classified into three clusters: agriculturists, labourers and pastoralists. The article examines the diversity of livelihoods involved, and considers where and how research should be directed to have greatest impact on poverty. Given that rural households are not homogeneous but dynamic entities, with diverse assets, capabilities and opportunities, the definition of household typologies can help to target development research. The article concludes that while agriculturists benefit most, poor labourers with enough land can also gain from pro‐poor agricultural research. The poorest households with little land, and pastoralists, benefit little or only indirectly.     

Fluid systems and mineralization in the north German and Polish basin

The North European Basin hosts mineral deposits like the Kupferschiefer and the Mississippi Valley Type deposits in the Silesian sub‐basin in Poland. The basement to this basin, exposed in the Harz Mts and in the Flechtingen and Calvörde Blocks, contains Mesozoic Pb–Zn vein mineralization and barite–fluorite deposits as well as massive hematite veins in the Rotliegend volcanics. A comparison of the mineralizing models of these deposits with results from a basin‐wide petrographic, fluid inclusion and stable isotope study shows that the genesis of the mineral deposits can be explained by fluid systems that were active during different stages of basin evolution. These comprise syn‐ to post‐magmatic fluids derived from or mobilized in the course of the Rotliegend magmatism, fluids convecting in the Rotliegend units during the extensional basin subsidence in the Permo‐Triassic and originating from progressive devolatilization of the basin sequence and fluids derived from the overlying Zechstein evaporites. Deep‐reaching fault systems developing during the Cretaceous tectonic reactivation enhanced fluid percolation from the surface to the deep sections of the basin sequence. Identification and correlation of these fluids across the basin and in the mineralizations provide the base for a basin‐wide metallogenetic model.     

Eric Voegelin and the Natural Law Tradition

Eric Voegelin’s criticism of Hans Kelsen’s legal positivism places him closer to the natural law tradition than to other legal traditions. This proximity could be interpreted as a defense of the contemporary relevance, or as an attempt to revive the natural law tradition in the twentieth century. However, Voegelin always avoids using the traditional terminology of natural law in his mature works, and expresses a certain ambiguity regarding its contemporary revival. To understand this problem, this article investigates the evolution of Voegelin's understanding of natural law and his criticism of different natural law traditions from Cicero to John Locke, especially his positive evaluation of Aristotle’s and Thomas Aquinas’s interpretations. Furthermore, it seeks to illuminate his position on the contemporary relevance of this topic, as well as to assess some of the recent interpretations that consider Voegelin as a natural law thinker.     

Plato and the Theodosian Code

The codification project initiated in 429 ad that resulted in the Theodosian Code was originally designed to integrate three types of law: one, imperial constitutions since Constantine; two, the legal material collected in the tetrarchic Codices Gregorianus and Hermogenianus; and three, a florilegium of juristic writings and responsa. The ultimate aim was to condense all this in a single comprehensive law book that would govern the entire life of the empire and its subjects. As this paper shows, such a project had no precedent in Roman legal history and in fact ran counter to the traditional multiplicity of legal sources in Rome. This prompts a question: from where did the intellectual fathers of the codification project drew inspiration for such a revolutionary idea? In the paper's second part, I argue that one important model for the codification project of 429 could have been the legal code Plato designed for the ideal state of the Laws.     

Estimation of Spatio-Temporal Correlations of Prehistoric Population and Vegetation in North America

We discuss a simple methodology to enable a statistical comparison of human population with the vegetation of North America over the past 13,000 years. Nonparametric kernel methods are applied for temporal and spatial smoothing of point data obtained from the Neotoma Paleoecology Database and the Canadian Archaeological Radiocarbon Database, which results in sequences of maps showing the development of population and different plant taxa during the Holocene. The estimation of smooth spatial and spatio-temporal cross-correlation functions is proposed in order to detect relationships between population and vegetation in fixed time intervals. Furthermore, the effects of varying environment on demographic changes as well as potential impacts of populations on plant taxa over time are analyzed. Pointwise confidence bands for cross-correlation functions are computed and a robustness analysis is performed to assess the significance of obtained results. Considering the example of oak, an interpretation of our results for eastern North America shows the value of this methodology.     

792 or 793? Charlemagne’s canal project: craft,nature and memory

In autumn 793, Charlemagne visited the fossatum magnum (the ‘big ditch’ or canal) between the Rhine and Danube. Excavations, dendrochronology and a re‐reading of Carolingian Annals shed new light on the chronology and setting of this canal, which was planned in 792, initiated in 793, and abandoned later that year. The abandonment is attested by both written and archaeological evidence. The different versions of the annals offer a unique opportunity for comparison with the archaeological record. Evidence that works of Vitruvius circulated in the Carolingian court suggests that Charlemagne’s advisers were drawing on classical tradition when they pitched the idea of digging the canal.
