Understanding irrigator bidding behavior in Australian water markets in response to uncertainty
Full text linkWater markets have been used by Australian irrigators as a way to reduce risk and uncertainty in times of low water allocations and rainfall. However, little is known about how irrigators’ bidding trading behavior in water markets compares to other markets, nor is it known what role uncertainty and a lack of water in a variable and changing climate plays in influencing behavior. This paper studies irrigator behavior in Victorian water markets over a decade (a time period that included a severe drought). In particular, it studies the evidence for price clustering (when water bids/offers end mostly around particular numbers), a common phenomenon present in other established markets. We found that clustering in bid/offer prices in Victorian water allocation markets was influenced by uncertainty and strategic behavior. Water traders evaluate the costs and benefits of clustering and act according to their risk aversion levels. Water market buyer clustering behavior was mostly explained by increased market uncertainty (in particular, hotter and drier conditions), while seller-clustering behavior is mostly explained by strategic behavioral factors which evaluate the costs and benefits of clustering.Alec Zuo, Robert Brooks, Sarah Ann Wheeler, Edwyna Harris, and Henning Bjornlun
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
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 linkWe 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
COLONIALISM AND LONG-RUN GROWTH IN AUSTRALIA: AN EXAMINATION OF INSTITUTIONAL CHANGE IN VICTORIA'S WATER SECTOR DURING THE NINETEENTH CENTURY
No full textDAMS AND DISPUTES: WATER INSTITUTIONS IN COLONIAL NEW SOUTH WALES, AUSTRALIA, 1850-1870
Full text linkThis paper will analyse the operation of the British common law of riparian rights in the Riverina District of New South Wales (NSW), Australia between 1850 and 1870.* Theorists argue that the predisposition of people to fight over or cooperate to exploit valuable resources depends on how well property rights are defined and enforced.†The operation of the riparian doctrine in the Riverina provides an empirical, historical example of why inefficient property rights promote violence. Violence in this instance was based on collective action directed at the destruction of water supply infrastructure, specifically dams, constructed on various rivers within the Riverina. This paper considers why collective action in violence did not spill over into infrastructure construction. It is argued that the failure of collective action was due to its high costs stemming from several factors: failure to meet optimal group size; problems of free riders; hold-up concerns; and the introduction of a much disputed land policy in 1861 referred to as selection.
