Record of the meso- and neoholocene palaeoenvironmental changes in the Jesionowa landslide peat bog (Beskid Sądecki MTS. Polish Outer Carpathians)

The paper presents an analysis of depositional sequences of landslide peat bog situated in the depressions developed within the landslide landforms Jesionowa in the Beskid Sądecki Mts. (Outer Carpathians). The peat bog, with depositional sequence 2.80 m long, started to form at the beginning of the Atlantic Phase ca. 6390–5910 cal BC. Palynological and lithological analyses as well as several (14) radiocarbon age determinations of different horizons in the sediments enabled the reconstruction of palaeoenvironmental changes during the Meso-and Neoholocene. The increase in climate humidity at the beginning of the Subboreal and Subatlantic Phases was observed as delivery of minerogenic material to the peat bog basin and formation of a mineral horizon and an illuvial level within the peat. The particularly intensive delivery of allochthonous material to the peat bog took place at the beginning of the Subboreal Phase and was the result of both significant humid climate and increased human impact (colonization of the Funnel Beaker Culture) in the landslide area. Similar influence of younger colonisations of landslide area (Przeworsk Culture and, later, Valachian colonisation) was also recorded within the deposits of peat bog (illuvial and mineral horizons) in the early Subatlantic Phase. Rejuvenation of the landslide zone and formation of the younger landslide were connected with the increase in climate humidity at the beginning of the Subboreal Phase. The peat bog deposits situated within this younger landslide, which are ca. 1.8 m thick, are significantly contaminated with mineral material.     

1. CONSTRUCTING A SELECTIONIST PARADIGM

In his latest contribution to the application of Darwinian evolutionary thinking to the social sciences, W. G. Runciman conceives of human behavior as resulting from three levels of selection—biological, cultural, and social. These give rise, respectively, to evoked, acquired, and imposed patterns of behavior. The biological level is hardly controversial, but to draw a distinction between separate cultural and social selective processes is more problematic. Runciman takes memes to be the variants competitively selected at the cultural level and the practices constituting rule‐governed roles to be the variants competitively selected at the social level—thus preserving separate spheres of research for anthropology and sociology. It is not clear, however, what drives cultural and social evolution. Nor are the three levels theoretically well integrated. The book's strength lies in the numerous examples provided of how the application of selectionist theory illuminates and enriches sociological and historical explanations and contributes to the construction of historical narrative.     

The Matter of Carbon: Understanding the Materiality of tCO2e in Carbon Offsets

Abstract: This paper examines the socio‐natural relations inherent in the commodification of carbon reductions as they are generated in energy‐based carbon offset project activities, and abstracted to wider market systems. The ability to commodify carbon reductions takes place through a socionatural–technical complex that is defined by the material nature of technology's interaction with the atmosphere, local social processes and the evolving governing systems of carbon markets. Carbon is not unproblematically commodified: some projects and technologies allow a more cooperative commodification than others. The examples of a hydroelectricity plant and an improved cookstove project in Honduras are used as empirical case studies to illustrate the difficulties and opportunities associated with the relational aspects of carbon commodification. Drawing upon select literatures from post‐structural thought to complement the principal lens of a more structural, materiality of nature analysis, the paper also outlines the reasons why carbon offset reform is needed if offsets are to more progressively engage debates about climate mitigation and North–South development.     

Ideology,Power, and the Structure of Policy Networks

This article investigates the role of power and ideology in the endogenous formation of policy networks. According to the Advocacy Coalition Framework (ACF), shared ideology (conceptualized as a system of policy‐relevant beliefs and values) is the primary driver of collaboration within policy subsystems. On the other hand, Resource Dependency Theory suggests that power‐seeking is an important rationale behind network structure, and that collaborative ties are formed primarily on the basis of perceived influence. Hypotheses are tested using a new method of egocentric network correlation, based on survey data of policy networks in five regional planning subsystems in California (N = 506). Results suggest that ideology is an important force behind network cohesion: Not only do policy elites systematically avoid networking with ideologically dissimilar actors but collaborative ties are also systematically formed among actors with shared beliefs. Power‐seeking does not operate on a network‐wide scale but may drive network formation among coalitions of ideologically similar agents.
