Anthropogenic and climate signals in late-Holocene peat layers of an ombrotrophic bog in the Styrian Enns valley (Austrian Alps)
No full textUsing peat bogs as palaeoenvironmental archives is a well-established practice for reconstructing changing climate and anthropogenic activity in the past. In this paper, we present multi-proxy analyses (element geochemistry, pollen, non-pollen palynomorphs, stable Pb isotopes, humification, ash content) of a 500 cm long, 14C-dated peat core covering the past ∼5000 years from the ombrotrophic Pürgschachen Moor in the Styrian Enns valley (Austrian Alps). Early indications of low settlement and agricultural activity date to ∼2900 cal BCE. An early enrichment of Cu was found in peat layers corresponding to the late Copper Age (∼2500 cal BCE). These enrichments are attributed to Cu mining activities in the Eisenerz Alps. More pronounced increases in cultural indicators (cultivated plants, shrubs, herbs, charcoal) in the pollen record and enrichments of trace metals suggest significant human impact in the vicinity of Pürgschachen Moor in the middle Bronze Age (∼1450–1250 cal BCE), in the late Bronze Age (∼1050–800 cal BCE) and in the period of the late La Tène culture (∼300 cal BCE–1 cal CE). The greater part of the Iron Age and the Roman imperial period are each characterized by a general decline in anthropogenic indicators compared to previous periods. Distinct enrichments of Pb and Sb in the sample that corresponds to ∼900 cal CE are attributed to medieval siderite mining activity in the immediate vicinity of Pürgschachen Moor. The results of this interdisciplinary study provide evidence that strong, climate-controlled interrelations exist between the pollen record, the humification degree and the ash content in an ombrotrophic environment. Human activity, in contrast, is mainly reflected in the pollen record and by enrichments of heavy metals. The study indicates a dry period in the region of the bog around ∼1950 cal BCE

Non-tax revenue and subnational democracy: evidence from Colombia
No full textAn influential group of political economists posits a negative relationship between the relative size of non-tax revenues in public balance sheets and the level of democracy in a given county. While empirical evidence for this proposition is largely based on cross-national studies, scholars have largely neglected subnational contexts as important domains of research. Addressing this disjuncture, the author studies the electoral impact of two important subnational non-tax revenues - natural resource royalties and central-government fiscal transfers - at the municipal level in Colombia. Employing a propensity score matching approach to attenuate problems of omitted variable bias, a quantitative analysis of Colombia's 1119 municipalities shows that higher levels of fiscal transfers and petroleum royalties had no discernible impact on the average level of competitiveness in the 2007 and 2011 municipal elections. If anything, there seems to be a positive impact of non-tax revenues on electoral contestation. Supported by qualitative evidence from theoretical outliers in the set of observations, the results suggest that non-tax revenue promotes electoral competition by raising the stakes of attaining political office. At the same time, abundance in fiscal transfers and resource royalties may undermine democratic governance through means that are not reflected in electoral margins.M.A.Includes bibliographical referencesIncludes vitaby Lukas Konstantin Kelle
