    Unmasking the Porter hypothesis: Environmental innovations and firm-profitability

    No full text
    We examine impacts of different types of environmental innovations on firm profits. Following Porter's (1991) hypothesis that environmental regulation can improve firms' competitiveness we distinguish regulation induced and voluntary environmental innovations. We find that innovations which reduce environmental externalities reduce firms' profits, as long as they are induced by regulations. However, innovation that increases a firm's material or energy efficiency in terms of material or energy consumption has a positive impact on profitability. This positive result holds both for regulation induced and voluntary innovations, although the effect is significantly larger for regulation-driven innovation.We conclude that the Porter hypothesis does not hold in general for its 'strong' version but has to be qualified by the type of environmental innovation. Our finding rest on firm level data from the German part of the Community Innovation Survey in 2009. --Environmental innovation,environmental regulation,Porter hypothesis,competitiveness

    Unified mathematical treatment of complex cascaded bipartite networks: The case of collections of journal papers

    No full text
    In this study, a mathematical treatment is proposed for analysis of entities and relations among entities in complex networks consisting of cascaded bipartite networks. This treatment is applied to the case of collections of journal papers. In this case, entities are distinguishable objects and concepts, such as papers, references, paper authors, reference authors, paper journals, reference journals, institutions, terms, and term definitions. Relations are associations between entity-types such as papers and the references they cite, or paper authors and the papers they write. An entity-relationship model is introduced that explicitly shows direct links between entity-types and possible useful indirect relations. From this a matrix formulation and generalized matrix arithmetic are introduced that allow easy expression of relations between entities and calculation of weights of indirect links and co-occurrence links. Occurrence matrices, equivalence matrices, membership matrices and co-occurrence matrices are described. A dynamic model of growth describes recursive relations in occurrence and co-occurrence matrices as papers are added to the paper collection. Graph theoretic matrices are introduced to allow information flow studies of networks of papers linked by their citations. Similarity calculations and similarity fusion are explained. Derivation of feature vectors for pattern recognition techniques is presented. The relation of the proposed mathematical treatment to seriation, clustering, multidimensional scaling, and visualization techniques is discussed. It is shown that most existing bibliometric analysis techniques for dealing with collections of journal papers are easily expressed in terms of the proposed mathematical treatment: co-citation analysis, bibliographic coupling analysis, author co-citation analysis, journal co-citation analysis, Braam-Moed-vanRaan (BMV) co-citation/co-word analysis, latent semantic analysis, hubs and authorities, and multidimensional scaling. This report discusses an extensive software toolkit that was developed for this research for analyzing and visualizing entities and links in a collection of journal papers. Additionally, an extensive case study is presented, analyzing and visualizing 60 years of anthrax research through a collection of journal papers. When dealing with complex networks that consist of cascaded bipartite networks, the treatment presented here provides a general mathematical framework for all aspects of analysis of static network structure and network dynamic growth. As such, it provides a basic paradigm for thinking about and modeling such networks: computing direct and indirect links, expressing and analyzing statistical distributions of network characteristics, describing network growth, deriving feature vectors, clustering, and visualizing network structure and growth

    What does it mean to be an academic? A public intellectual? What is the role of the universities today? Who better to ask than the people who for decades have worked, taught, struggled and lived in these places. Steven Shapin is the Franklin L. Ford Research Professor of the History of Science at Harvard University. He was part of the Science Studies Unit at Edinburgh University in the 1970s and went on to co-author the influential Leviathan and the Air-Pump: Hobbes, Boyle, and the Experimental Life. In this book you can read about his journey through the heydays of Science Studies and his thoughts on the future of universities. In the Questions & Afthoughts series you will meet some of the finest and most distinguished senior professors—you will meet living history. They are interviewed by young graduate students, who are eager to learn from past experiences of trial and error in academia, both professionally and personally.What does it mean to be an academic?
