Biological Survey of Elizabethtown College
Get PDFThe campus of Elizabethtown College possesses various ecosystems that frequently are overlooked by the student body and community. These ecosystems include forests, meadows, wetlands, streams, and ponds and provide habitat for a variety of plants and animals. We are advocating for the college to recognize these campus areas as the “Natural Lands of Elizabethtown College.” The goal of our project was to determine what species inhabit these natural lands. Our primary taxonomic focus was on birds. We determined the absence and presence of bird species common to the eastern United States. About three times a week for three weeks in late May and early June of 2019, we birded in seven locations for 15-minute intervals. These locations included meadow, wooded, pond, and residential ecosystems. We determined the probabilities of occupancy and detection of birds within these ecosystems. In addition to birds, we also surveyed for salamanders and aquatic macroinvertebrates in streams on campus. We also mapped patches of milkweed on campus in anticipation of future research on monarch butterflies. These data on various taxonomic groups are a first step to understanding the biodiversity of the “Natural Lands.” The Natural Lands of Elizabethtown College will demonstrate our college’s commitment to preserving biodiversity and providing opportunities for the educational, physical, and mental well-being of students by creating connections with nature
Increasing Awareness of Natural Areas on the Elizabethtown College Campus through Digital Story Maps
Get PDFThe campus of Elizabethtown College includes multiple types of ecosystem—forests, meadows, wetlands, streams, and ponds. These areas can serve as outdoor extensions of the classroom, presenting convenient settings for research projects. They are also a valuable recreational resource. To increase student awareness of the natural areas of the campus, we are utilizing ArcGIS technology to create a story map of trails on campus, to be used for self-guided tours or tours guided by student volunteers. Story maps define the path and draw attention to notable or ecologically interesting locations along the path. Photos and detailed descriptions in the story map act as a starting place for students who want to know more about features of campus related to sustainability. We are creating two mapped versions of the trail—they vary in length, type of terrain, difficulty, and intended audience. The more basic trail, which only covers paved and packed gravel terrain, will be accessible to prospective students and families interested in learning about Etown’s natural lands and the learning opportunities they offer. The second trail is a more rigorous hike through densely wooded areas, best suited for those with a desire to learn and a willingness to make the more challenging trek. In addition, we are planning ecological restoration of a section of forest. Restoration will involve removal of invasive plants and planting with selected native species, with the objective of increasing plant and animal biodiversity of the restored area. Our goal is for the area we restore and the process we follow to serve as a model for future student restoration projects
Anxiety: Environmental and Otherwise
Get PDF“Anxiety: Environmental and Otherwise” is a collection of works from different genres and of different lengths. The pieces vary in tone from professional to confessional. Nonfiction sits next to fiction and experimental forms. The common thread that binds the pieces together is one of personal values. The heart of the collection is the importance of discovering one’s self and then making the choice to nurture that identity. With all of life’s strangeness and the impossible abundance of experiences, it can be difficult to truly see one’s self. It’s even more difficult to see why any of us are the way that we are. The pieces in this collection examine impacts: how anxiety disorder can affect a person, what people have done to this planet, and what the planet can do to its people. This collection is one girl’s attempt at introspection, all with the hope that something positive will come of it. “Anxiety: Environmental and Otherwise” grasps for understanding and begs for progress. It’s a plea, a lament, and a celebration
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
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
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
