Discursive Agency: (Re‐)Conceptualizing Actors and Practices in the Analysis of Discursive Policymaking

Interpretive discourse analysis commonly claims to address the interrelation between actors and discourses. However, the analytical focus of most approaches is on structures (discourses) while much less attention is paid to agency. This paper explicitly addresses discursive agency in two steps. First, we systematically review theoretical and analytical dimensions of agency in existing interpretive discourse analysis approaches. This review reveals a set of shared assumptions; most notably a concept of “trialectic” agency emphasizing the constitution of agency among the individual, the (discursive) structures, and the researcher's interpretation. Second, we propose an analytical heuristic, the Discursive Agency Approach, which is developed on the basis of the review and own empirical data. The proposed approach consists of four elements: (1) policy discourses, (2) political institutions, (3) agents defined via a set of characteristics, and (4) strategic practices. This approach is meant to facilitate a systematic exploration of agency under a discourse perspective, tackling the question of how a policy is constituted through the agency ascribed to its proponents in dynamic discursive processes, and how actors acquire political relevance through discursive means. To enable this goal, we propose distinct research steps and associated methods that link the approach to existing means of analysis.     

New light on old pumice: the origins of Mediterranean volcanic material from ancient Egypt

This paper presents and discusses the Neutron Activation Analysis (NAA) results newly obtained from pumice pieces found decades ago at the Egyptian sites of Maiyana, Sedment, Kahun, and Amarna – now in the collections of the Ashmolean Museum, Oxford, and the Petrie Museum of Egyptian Archaeology, London – which could be successfully related to several volcanic eruptions in the Mediterranean. The work contributes to the constant accumulation of knowledge concerning the first appearance of pumice from the so-called Minoan eruption of the Santorini volcano. In addition, it unexpectedly sheds more light on the long-distance trade of Mediterranean volcanic material in the Bronze Age world by disclosing another connection between Lipari and the Eastern Mediterranean.     

THE FUTURE TRAJECTORY OF U.S. CO2 EMISSIONS: THE ROLE OF STATE VS. AGGREGATE INFORMATION*

ABSTRACT This paper provides comparisons of a variety of time‐series methods for short‐run forecasts of the main greenhouse gas, carbon dioxide, for the United States, using a recently released state‐level data set from 1960–2001. We test the out‐of‐sample performance of univariate and multivariate forecasting models by aggregating state‐level forecasts versus forecasting the aggregate directly. We find evidence that forecasting the disaggregate series and accounting for spatial effects drastically improves forecasting performance under root mean squared forecast error loss. Based on the in‐sample observations we attempt to explain the emergence of voluntary efforts by states to reduce greenhouse gas emissions. We find evidence that states with decreasing per capita emissions and a “greener” median voter are more likely to push toward voluntary cutbacks in emissions.
