One way that universities across the United States are addressing sustainability and promoting environmental awareness on campus is through food. Food sustainability is primarily achieved by closing the loop on campus food systems and educating the student body on the importance of its food choices. My thesis project aims to identify what other universities have done to achieve success in their food initiatives and figure out how to develop these initiatives at the University of Nevada, Reno (UNR). I found that by integrating the goals and efforts of student, faculty, and food services, a campus-wide food movement can be developed, and sustainability can be achieved. UNR will need to form a food working group to address student awareness of food sustainability as well as farming, local food sourcing, and composting programs to close the loop on campus
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

Activity of bats in thinned, unthinned, and old-growth forests in the Oregon Coast Range
Get PDFTen species of bats occur in the Oregon Coast Range and are hypothesized to be
associated with late-successional forests. The development of characteristics of late-successional
forests in young forest stands can be accelerated through silvicultural
practices such as thinning I examined the effects of thinning on the use of forests by bats
in the Oregon Coast Range. I used automated ultrasonic detectors to record bat calls in
50- to 100-year-old thinned and =thinned stands as well as in old-growth (2200-year-old)
stands in 11 sites in the Oregon Coast Range during the summers of 1994 and 1995. I
compared bat activity levels among the 3 stand types. In addition, I classified bat calls into
1 of 5 species groups: Eptes/Las, Myev/vo, Myyu/ca, MythCory, and Mysp. I measured
selected vegetation and environmental variables in conjunction with bat activity. I also
compared bat activity on roads with activity in the stand interior at 1 site.
Bat activity was higher in old growth than in young stands, and higher in thinned
than in =thinned stands in 1995 and over both seasons combined. I did not detect a
difference in bat activity among stand types in 1994, until I removed 1 site from the
analysis. The Mysp and MythCory species groups exhibited differences among stand
types. Bat activity along roads was higher than activity within stands.
Tree density, tree diameter, tree height, shrub cover, and shrub height varied
significantly between old-growth and young stands. Tree density, tree diameter, shrub
cover, canopy cover, and crown height varied significantly between thinned and unthinned
stands. Bat activity, overall or by species group, was significantly related to structural
variables, including mean snag diameter, mean distance from the detector to snags, and
percent shrub cover.
My results suggest that bats are sensitive to stand structure and that silvicultural
practices, such as thinning, which promote development of structural characteristics found
in old-growth stands, would benefit bat populations. Further study is needed to clarify the
habitat preferences of separate bat species and to specify habitat elements required by bat
species
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
Ecoimmunology and Demography of Recruitment in Swainson’s Hawks
Get PDFSwainson’s Hawks are a long-lived migratory species that breed throughout North America. Swainson’s Hawks frequently forage and nest in modified-agriculture landscapes, which often support large prey abundances. Breeding surveys across the state of California estimated a 91% decline in the number of breeding pairs in 1979, prompting a listing-status of “threatened” in 1983. A long-term monitoring project for the species was developed in Butte Valley, California in association with this state-wide survey and has run continuously from 1979 to the present. Examination of this long-term breeding and reproductive data shows a continuum of territory occupancy and productivity values. This heterogeneity becomes especially apparent when examining differences between individual territories. I explored the differences between territories and its role on natal conditions using immune system development as a framework. The hypothesis being that nestlings benefitting from favorable conditions are able to invest in stronger immune systems. Mixed effects analyses indicated a significant link between extended territory occupancy history, an index of habitat quality, and stronger immune systems in nestlings in 2013 but not in 2015. I also examined long-term trends in population size across the last three decades. I used multi-state models to test hypotheses involving trends in recruitment rates and to estimate first-year survival. Models that accounted for the permanent ban of “monocrotophos” pesticide use across the wintering range received the most support. Indicating that the disuse of this pesticide in 2000, was particularly important for this species. This result emphasizes the necessity and value of conservation work
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
