Response to “Withering the coloniality of the forest transition?”
No full textOur “Whither the Forest Transition’ article (Rudel et al. 2020) reviews the usefulness of the forest transition concept in light of recent global changes in forest cover and forest policies. In their comment, Liebman and Gagliano (2021) claim that our argument ignores the place of the forest transitioning nations in the world system. In other words, they find our argument about the emergence of latecomer forest transitions insufficiently ‘relational’. Their critique misreads our argument in two fundamental respects...Fil: Rudel, Thomas K.. Rutgers University; Estados UnidosFil: Meyfroidt, Patrick.

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
The emerging soybean production frontier in Southern Africa: conservation challenges and the role of south-south telecouplings
Full text linkSoybean expansion has been a strong driver of deforestation and biodiversity loss in South America. Here we highlight strong similarities in environmental, institutional, and other contextual conditions among South American (SAM) and Southern African (SAFR) dry forest and savanna regions, and compile evidence for an emerging soybean production frontier in Southern Africa. Knowledge transfer, cooperation, and direct investment between South American and Southern African countries constitute crucial elements of soybean expansion in Africa. Comparing maps of soybean suitability, biodiversity, and carbon revealed substantial and spatially diverse trade-offs, suggesting that the emerging soybean frontier in Southern Africa may poses major challenges for conservation. An increased focus of conservation science on agricultural expansion and intensification in Southern African, as well as strong environmental policies for balancing agricultural production and conservation goals, are needed to mitigate potentially large trade-offs. The coupling of production frontiers should be a vehicle for the transfer not only of agricultural technology and production models, but also of experiences in environmental governance on emerging agricultural frontiers
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
Considering land use complexity and overlap is critical for sustainability planning
No full textLand use is both a driver and a lever to address sustainability challenges like biodiversity loss, climate change, and food security. Yet, it is often oversimplified in sustainability planning, ignoring the diversity of actors or the multiple claims on land. We developed an approach to capture the complex and contested nature of land use by mapping it as social-ecological systems that can overlap in space. Demonstrating our approach for the Dry Chaco and Chiquitano forests in South America revealed three main insights. First, we mapped actors that are typically overlooked, such as forest-dwelling smallholders. Second, substantial land use overlap, particularly between smallholders and agribusinesses, signals land competition that risks marginalizing smallholders. Third, our maps showed conservation areas overlapping with other land systems, highlighting opportunities for co-benefits but also competition. Overall, our transferable approach captures land use complexity and visualizes often overlooked actors, thereby potentially contributing to more just and effective sustainability planning.Instituto de Investigación Animal del Chaco SemiáridoFil: Pratzer, Marie.

Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
