A common-pool resource experiment in acequia communities
Farmers and rural advocates in New Mexico assert that traditional irrigators are better adapted to water scarcity and variability than other communities. Data to actually test this are often scarce, but such information could be useful for planning the state’s water future, especially as climate change predictions tend toward less reliable supplies. This paper reports results from a common pool resource (CPR) experiment that simulates irrigating behavior using two groups: rural irrigators and undergraduate students. Despite predictions to the opposite, there was no significant difference between mean withdrawals or predictions of other players’ behavior. On average, both groups withdrew above the social optimum but below the Nash equilibrium. This work appears to be the first example of a common pool resource experiment conducted with traditional New Mexican irrigators
Estimating Willingness to Pay to Protect Acequia Irrigation and Culture: Lessons from San Miguel County, NM
[EN] Traditional gravity fed irrigation systems in Hispano communities in New Mexico, USA, are
referred to as acequias. Water scarcity is currently motivating negotiations between acequias and
municipalities over sharing agreements. Research on willingness to pay to protect and maintain acequias
is still scarce. These valuation data could be helpful to improve the quality of water resources decision
making and therefore rural development strategies in this region, which is relatively poor compared to
the US average. Data from an open-ended CVM survey are used to examine WTP for a program
designed to strengthen and perpetuate irrigation and culture on the acequias of El Río de las Gallinas, in
rural northeastern New Mexico. Results indicate that the community supports the program in general,
with higher levels of support among rural residents and Anglos.Raheem, N. (2015). Estimating Willingness to Pay to Protect Acequia Irrigation and Culture: Lessons from San Miguel County, NM.

Going Beyond Counting First Authors in Author Co-citation Analysis
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
Variations on the Author
“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
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
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
