Episode 16: Soil Health Tests
No full textRuntime 32:46In this episode of the Nutrient Management Podcast, we discuss soil health tests. What is the consensus definition of soil health? What should growers look for in soil health tests, and how should they go about testing their fields? What research is available in Minnesota tying soil health tests to crop performance and yield?McDivitt, Paul; Kaiser, Dan; Cates, Anna; Fernandez, Fabian; Rosen, Carl. (2019).

Impacts of Soil Health Management on Environmental Quality: A Research Review for Minnesota
No full textThis review was undertaken to summarize research on the impact of four in-field practices (cover crops, reduced tillage, perennials, and crop rotations) on nutrient losses, soil carbon, and runoff/erosion in Minnesota. Social, economic, and policy considerations, while highly relevant to agricultural decision making and design of incentives, are beyond the scope of this review. To maximize relevance of findings, this review focused on data from studies conducted in Minnesota, along with data from Wisconsin, Iowa, Michigan, South Dakota and Illinois if applicable. Since Minnesota has unique climatic conditions, findings from meta-analyses were not included, except as background or where regional differences were noted.This report will help inform three efforts: (a) a State Soil Health Action Framework, funded by the McKnight Foundation through the MN Board of Water and Soil Resources (BWSR) and the Minnesota Office for Soil Health (MOSH); (b) a science synthesis to support updates to the Nutrient Reduction Strategy, led by the MN Pollution Control Agency (MPCA) with technical support from the University of Minnesota; and (c) the development of a Soil Health Impact Calculator, funded by BWSR through MOSH.Reilly, Evelyn; Cates, Anna.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
