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
Impacts of Land Use on Mobile Source CO2 Emissions
No full textThe issue of mobile source emissions has not been as prominent as energy efficiency or renewable energy in the national climate policy debate. This analysis examines the potential impact of land use patterns on carbon dioxide emissions from mobile sources. Specifically, this report addresses the CO2 emissions of non-road construction equipment and light-duty passenger vehicles associated with sustainable land use patterns and urban sprawl. As local governments and developers begin to plan and take action to reduce CO2 emissions, tools will be needed to quantify emission reductions associated with local land use patterns. The objective of this project is to provide an inventory tool in Microsoft Excel that calculates the magnitude of emissions from construction and highway vehicles associated with various land use patterns
HOME ENERGY CONSUMPTION ESTIMATION BY END USE AND ENERGY EFFICIENCY UPGRADE RECOMMENDATIONS
Get PDFResidential energy consumption is becoming an ever-growing sector, in 2012 accounting for 21.2% of total consumed energy in the United States. People have been focused on exploring potential strategies to lower the associated energy consumption, including energy efficiency improvement and policy adjustment. However, in the absence of detailed breakdown of energy consumption, it is hard to effectively apply energy efficiency upgrades, meaning a necessity of getting a deep understanding of the energy consumption estimates.
To achieve the breakdown of energy consumption, this project primarily focuses on the individual home energy consumption, through estimating the energy consumed in space heating, space cooling, water heating, and appliances. In particular, multiple-regression method is employed to construct the prediction model, and Residential Energy Consumption Survey (RECS) is used as the source data, which includes more than 12000 samples and has satisfactory data reliability.
As a result, many select factors are proven to be closely associated with certain energy end use. For instance, space heating/cooling energy consumption is greatly driven by the housing unit square feet, and a bigger house would result in more energy consumed in the heating and cooling sector, attested by a great coefficient in the constructed regression model. In addition, other geographic factors, such as climate region and heating degree-days, also indicate influences on the energy consumption pattern. This project further applied the regression models to establish a database of estimation by taking census data as input, providing reference cases for individual home energy efficiency upgrades
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
NYC CO-OP AND CONDOMINIUM GUIDE TO ENERGY EFFICIENCY UPGRADES
No full textThe purpose of this project is to help Better Buildings New York (BBNY), a non-profit organization focused on increasing energy efficiency and decreasing energy bills of NYC buildings, educate multifamily co-op and condo boards on energy efficiency upgrades and retrofits available for their buildings. The current market for these technologies and opportunities is vast, and at times, overwhelming. Various energy efficiency technologies exist with different costs, energy savings and impacts. Therefore, there was a need to create a medium for which these technologies and benefits could be communicated in a quick, non-technical, and easily understood manner.
BBNY’s audience for this project is co-op and condo boards in multifamily apartment buildings. In these types of buildings, they are the decision-makers who are responsible for making renovation/retrofit choices. Therefore, this project focuses around the myriad of energy efficient technologies that are applicable to multifamily building environments, and how to convey this information to this type of audience. The research team used literature review, NYC building data sets, and Department of Energy modeling software (eQUEST) to vet a list of technologies BBNY was interested in presenting to board members. Each technology was researched to find information relating to five areas: capital costs, energy efficiency gains, payback periods, consistency of payback periods, and difficulty of installation. Once this information was collected, the team decided that there would be two main deliverables for the client.
The first deliverable is a full academic report that delves into the intricate methodology and technical analysis used to evaluate each technology. This report serves as a reference for understanding the various types of technologies available for multifamily retrofits, and a breakdown of their functionality. However, due to the background of the intended audience, the team wanted to create a way for the technologies to be easily understood and compared to one another.
Therefore, a second deliverable was developed with a ranking system to rate each of the technologies within the five previously defined areas. The ranking score used quantitative and qualitative information from the original research, and provided a way to compare the technologies against each other. The first part of the second deliverable is a condensed brochure that takes each technology and evaluates it on a single page, with a chart displaying the ranking score it received when compared to the whole list of technologies covered. The second part of the second deliverable is an MS Excel tool that offers a dynamic ranking system to provide a personalized list of technologies related to building attributes and user preference.
From these two deliverables, BBNY has the means to provide co-op and condo boards with guidance on energy efficient, retrofit technologies. The decision-makers in thousands of multifamily buildings now have a starting point to learn what technologies may be appropriate for further investigation. It is through these types of grassroots, information campaigns that energy efficiency gains and carbon footprint reductions in multifamily buildings can become a reality in New York City
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
