The Future of Minnesota Drinking Water: A Framework for Managing Risk
No full textThe charge for this report was to identify opportunities for the Minnesota Department of Health (MDH) to
better manage risks to Minnesota’s drinking water. In addition to examining literature and experience in
other jurisdictions, our recommendations are informed by ten discussions with a panel of research and
policy experts, and a panel of stakeholders including representatives of large and small community
utilities, the water technology industry, state agencies, and well owners.Calow, Peter; Lewandowski, Ann; Levers, Lucia; Kirby, Eileen. (2020).

Riparian Buffer Science: Status and Research Needs
No full textA summary of research, applications to management and the new Minnesota buffer rule
Status of the science: What do we know?
Erosion and nutrient loss from upland areas, streambanks, bluffs, ravines, and river banks have been contributing to water quality problems throughout the state. Furthermore, changes to the structure and vegetation of waterbodies have impacted the health of aquatic life over the years.
Impairments from these changes are associated with problems pertaining to aquatic life, drinking water, and algal blooms in Minnesota’s water bodies and water in other states downstream. In order to improve waters across the state and water discharging into neighboring states, Minnesota has been implementing best management practices (BMPs). Riparian buffers are one type of BMP being used to reduce contaminants released into the state’s waterways.University of Minnesota Water Resources CenterGordon, Brad; Lenhart, Chris; Lewandowski, Ann; Wyatt, Gary; Current, Dean.

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
