Neighborhood Voices: A Lincoln Park Climate and Water Impacts Survey
No full textTo see more One Block at a Time project materials, click the "One Block at a Time project" link under "Keywords" above.In 2022, a survey of Lincoln Park neighborhood residents’ perspectives and observations was conducted in order to better understand community perspectives on solutions and challenges related to flooding in the neighborhood. The results of this survey suggest that respondents are concerned about increased flooding in their communities. Survey respondents reported that they feel it is the responsibility of the city and state to manage the problem, but also reported that they want more information about what they can do to mitigate the risk themselves. Additionally, they reported that they value existing green and blue spaces, and want more of them; they also stated that they feel it is important that these spaces serve to manage stormwater in addition to providing social benefits to community members. This document reports the results of that survey.This report was prepared in collaboration with the University of Minnesota Sea Grant College Program using federal funds under award NA18OAR4170101 Amend.19 from the National Oceanic and Atmospheric Administration's National Sea Grant College Program, U.S. Department of Commerce.Carlson, Jessy R; Sowers, Maia A; Bliss, Morgan; Rodman, Madison G; Sprague, Tiffany A.

Green Stormwater Infrastructure Code Audits: Updating Local Regulatory Structures for a Changing Climate
No full textPoster presented at the 2024 St. Louis River Summit in Superior, Wisconsin.The impacts of climate change, such as increasingly intense storms and more frequent floods, mean regulatory frameworks designed to manage stormwater runoff in previous decades may no longer be effective; codes and ordinances may inadvertently prohibit or inhibit the use of nature-based approaches to managing stormwater runoff. To adapt to current and projected climate change scenarios, local governments need updated regulatory frameworks that effectively manage stormwater runoff in a changed climate. Adapting local regulations to promote systematic use of green stormwater infrastructure (GSI) and other nature-based solutions is a key strategy that can contribute to the development of resilient, climate-adapted communities.
We worked with ten urban and rural municipalities across the Duluth area to conduct code audits and assist with designing and accomplishing community-specific GSI objectives, and we are currently expanding this project to include Lake and Cook Counties. These participating communities display a diverse array of geographical and demographic characteristics. However, after working with these communities’ technical staff and elected representatives to assess their regulatory structures and internal policies for areas that could be updated to prepare for increased heavy precipitation events, we have noted some important themes regarding needs, challenges, and opportunities that cut across the region. This poster will share what we are hearing from these communities and whether these themes point to emerging climate adaptation needs in Northeast Minnesota.This poster was prepared in collaboration with the University of Minnesota Sea Grant College Program using federal funds under award NA22OAR4170098 from the National Oceanic and Atmospheric Administration's National Sea Grant College Program, U.S. Department of Commerce.Carlson, Jessy R; Hinds, Juli Beth; Rodman, Madison G; Sprague, Tiffany A.

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

Non-target Effects of Biological Control: Ecological Risk of Tyria jacobaeae (Lepidoptera: Erebidae) to Senecio triangularis (Asteraceae) in Western Oregon
No full textNon-target effects are one of the greatest potential risks of weed biological control programs, and understanding non-target effects of biological control at the population level is crucial for predicting when they will occur and altering the perception of biological control as a whole. In this thesis, we assessed the ecological risk of Tyria jacobaeae L. (Lepidoptera: Erebidae), the cinnabar moth, to Senecio triangularis Hook. (Asteraceae) in Western Oregon using a standard risk model that defines risk as the product of the hazard and the exposure to the risk (risk = hazard × exposure). Experimental manipulation of the timing of herbivory by cinnabar moth larvae revealed S. triangularis was sensitive to a match in phenology in year t between late instar larvae and S. triangularis capitula (flower heads) in the primordium, bud, and flower developmental stages. However, S. triangularis survival, growth, and reproduction in year t+1 were relatively insensitive to different timings and intensities of herbivory by cinnabar moth larvae in year t. A decade of observational regional data of populations of S. triangularis in Western Oregon showed a balance between cinnabar moth colonization and extinction and that the intensity of
cinnabar herbivory appears to be stable. Across all colonized sites and years sampled, about half of all sampled ramets (individuals of a clone, or genet) were attacked by cinnabar moth larvae and damage was generally moderate (if attacked, conditional mean = 49%, conditional median = 40% leaf area removed per ramet). Lastly, a six-year demographic study showed a fluctuating herbivore regime where marked S. triangularis genets experienced up to four years of herbivory greater than or equal to 75% leaf area removed. Together, this relatively low hazard of herbivory and a widespread but moderate exposure to herbivory support conclusions that T. jacobaeae poses a low to moderate risk to S. triangularis with the potential for this risk to change with changes in phenology and/or climate
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
