Creating a Timeline of Chumash Land Management
Full text linkIndigenous land management practices shaped the environment over thousands of years and promoted ecosystem health while providing for the Native people. The European colonization of North America and the forced assimilation of the Native people largely erased traditional land management practices, resulting in ecological degradation. There is a significant body of research regarding Indigenous land management practices, but there is a gap in examining how historical, social, and environmental events changed Indigenous land management practices, and how this affected the environment. Thus, the creation of a timeline to examine how these events shaped Chumash people’s land management practices from pre-contact to present day is proposed. This timeline would fill this gap in the research, while providing an opportunity for scholars and officials across disciplines to learn from the past to make decisions that benefit Indigenous people and the environment. The knowledge provided by the timeline would offer environmental solutions and highlight Indigenous perspectives. Working closely with the Chumash, the timeline would be created by synthesizing their contemporary perspectives with historical social, political, and environmental context to examine how these factors changed Chumash land management, and the effect this change had on the environment
Agricultural Water Management in a Changing Mid-Atlantic: Stakeholder Experiences and Attitudes Towards Alternative Water Sources, Weather Variability, and Related Factors
Full text linkWater and agriculture are inextricably connected, and so are the impacts of climate change upon water supplies which will impact agriculture with greater intensity as the earth continues to warm. In the mid-Atlantic, climate change will intensify extremes such as flood and drought, resulting in greater water quantity variability (NIACS). Other consequences of climate change will include significant sea level rise and saltwater intrusion, as well as increased temperatures and decreased water quality (NIACS). In a region already experiencing significant but commonly overlooked impacts on water quality and quantity due to population and development increases, land use modifications, and agricultural runoff, understanding stakeholder perspectives on agricultural water management in the region is imperative. This study interviewed 17 mid-Atlantic stakeholders, largely based in Maryland, which included farmers, extension agents, engineers, academics, and state agency personnel. These semi-structured interviews examined stakeholders’ perceptions and experiences with 1) water use and management in agriculture, including both freshwater and reusable resources; 2) past, existing and future weather variability; and 3) related factors impacting water use and management. Semi-structured interviews were completed to examine stakeholder perceptions towards nontraditional water sources and water conservation practices, with the intent of informing a future survey that would assess farmers’ willingness to use treated recycled wastewater in agriculture in order to mitigate increasing water supply variability due to climate change.https://digitalcommons.lmu.edu/cures_posters/1042/thumbnail.jp
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
Quantifying 14 Years of Restoration Impact at a Los Angeles Park Using Remote Sensing
No full textAscot Hills Park is an urban park in the El Sereno neighborhood of east Los Angeles that has undergone continuous restoration efforts to reintroduce California native trees and shrubs from 2011-2025. This study seeks to understand how a 14 year period of continuous restoration by a variety of stakeholders has changed the park by asking the following question: How has native plant cover changed over time? To answer this question, the change in percent native plant cover at the park from 2011-2025 was quantified using satellite imagery and machine learning software in ArcGIS Pro. Satellite images and ArcGIS Pro were also used to create a series of maps that visualize all the restoration efforts carried out by various stakeholders at the park over time. Native plant cover was shown to have significantly increased both visually and quantitatively by 93.3% within this time period, demonstrating that restoration at Ascot Hills Park has been successful. The restoration maps created within this project will be provided to restoration stakeholders as a record of their significant efforts and to inform future methods of restoration. This study provides a unique addition to the literature by examining continuous restoration at a single urban park in Los Angeles over an extended period. This study also quantifies the success of ongoing restoration efforts and informs future restoration strategies in order to increase the valuable ecosystem services that Ascot Hills Park provides to a disadvantaged neighborhood of Los Angeles found to have inadequate park access
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
