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
Evolution of Water Rights in the Nineteenth Century: The Role of Climate and Asset Type
Full text linkAppropriate 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
Dams 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

Treading water: an analysis of institutions and natural resources sustainability: the case of the Murray River
Full text linkDeposited with permission of the author. © 2002 Dr. Edwyna Margaret HarrisThis thesis considers the role of property right allocations and the degradation of Australia's Murray River. Specifically, this analysis focuses on the allocation of property rights to northern Victorian irrigation areas. Until recently, property rights to water and prices were determined in the political sphere as the government has historically taken an active role in the management of Murray River water. During the period of government intervention, salinity within the Murray increased significantly. This thesis argues that the effects of government intervention in setting price and quantity allocations contributed to the increasing degradation of the river system over time. Prices were set at a level that was too low to pay for the costs of irrigation infrastructure, maintenance and management. As such, farmers using the good substantially undervalued water. This led inefficient irrigation techniques and over watering to dominate because farmers were not subjected to the real cost of water provision. In turn, salinity levels in the Murray River increased. A major contributing factor to this price distortion was the gerrymandering of Victorian political boundaries that resulted in urban votes having less value than country votes. Due to this, political survival depended on the support of farmers. In turn, the government could not increase the price of water because that would mean election defeat. The absence of a water market led to farmers having no objective value placed on their subjective utility for water therefore, they substantially undervalued the good. As a result, it can be argued that government intervention in the administration of water from the Murray River promoted the degradation of the river through the rise of salinity.
Recently however, with the introduction of tradable water rights that subject fanners to market prices for water, the possibilities for sustainability of the Murray River have increased through the promotion of good environmental management by users who now face the true cost of their decision making. Generally, this thesis adds weight to the argument that government intervention in natural resource management can promote degradation rather than sustainability due to the institutional arrangement created by political administration affecting incentives at the user level. Importantly, this thesis adds to contemporary Australian literature through an increased understanding of how governments can hinder rather than help environmental preservation over time
