    Theory vs Reality: Making Environmental Use Rights Work in New Zealand

    Full text link
    The potential advantages in flexibility and efficiency of environmental use rights (such as permits and quotas) over prescriptive regulatory approaches have been well surveyed, and are being advocated in New Zealand now as a tool for achieving sustainable development. So why have they not been more widely adopted here? How can government help remove barriers and improve both economic and environmental outcomes in New Zealand? At the structural level the barriers tend to be well known, or presumed, as a lack of statutory frameworks or central government guidance, and information costs involved in defining the resource and in determining an appropriate rights framework to optimise its use. Even given these structural and technical barriers there remains the task of explaining why, since those barriers are not insuperable, little progress has occurred. Other factors include the extent to which such responsibility in New Zealand is delegated by central government, competing priorities for regional governments, lack of pressure on resources (eg; water in much of New Zealand), the difficulty of making contentious choices and strength of existing interests, reluctance to acknowledge any private rights to some resources, the relative ease of using existing regulatory tools, and low benefits relative to costs in small markets particularly where geographical distinctions exist such as for water and certain types of pollution. This suggests that the best focus for central government may be on better guidance, filling gaps in legislative frameworks, and providing or encouraging provision of the necessary institutions and systems in ways that allow economies of scope and scale. It is unclear how much scope there is for improvement but getting rid of unnecessary barriers, as long as it is done without unnecessary elaboration or restriction, will help secure whatever gains are out there to be had.Water, Property Rights, Transferability, Market Based Instruments

    Little Information, Efficiency, and Learning - An Experimental Study

    Full text link
    Earlier experiments have shown that under little information subjects are hardly able to coordinate even though there are no conflicting interests and subjects are organised in fixed pairs. This is so, even though a simple adjustment process would lead the subjects into the efficient, fair and individually payoff maximising outcome. We draw on this finding and design an experiment in which subjects re-peatedly play 4 simple games within 4 sets of 40 rounds under little information. This way we are able to investigate (i) the coordination abilities of the subjects depending on the underlying game, (ii) the resulting efficiency loss, and (iii) the adjustment of the learning rule.mutual fate control, matching pennies, fate-control behaviour- control, learning, coordination, little information

    Going Beyond Counting First Authors in Author Co-citation Analysis

    Full text link
    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Quality and safety for substances of human origins: scientific evidence and the new EU regulations

    Full text link
    The new European Union (EU) ‘Regulation on standards of quality and safety for substances of human origin (SoHOs) intended for human application’ is based on a long-standing diffidence towards offering compensation to donors of SoHOs. We point to recent, growing empirical evidence indicating that carefully designed compensation can increase the supply of SoHOs without negatively affecting quality and safety. We also elaborate arguments that address some of the moral concerns that motivate the aversion to payments. As member states proceed to adopt the new EU regulation, our article may provide insights on how to achieve both self-sufficiency and safety

    Variations on the Author

    Full text link
    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Appropriate Similarity Measures for Author Cocitation Analysis

    Full text link
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods
