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
Public Transportation: Resources Demand And Mobility - Impact On Companies In Boston, USA And Munich, Germany
Get PDFThis project researches the impact of access to public transportation on companies and their employees through a comparison between Boston, Massachusetts and Munich, Germany. Long commutes to work together with the traffic problems in the inner cities and the huge environmental impact of single occupancy vehicles, show the increasing importance of public transportation. After analyzing online sources through a literature review, interviews with representatives of different companies in both cities were conducted along with an online survey among the employees about their usage and opinion of the importance of public transportation system to their employer. In addition, to further the research, politicians’ perspectives on public transportation were included. The results revealed that companies and employees in Munich significantly rely on public transportation. Furthermore, accessibility to public transit influences the location decision of companies and employers. In Boston, on the other hand, public transit is not as widely used as many of the employees stated, that it is not suitable to their work schedule or they do not have access to it. Analyzing both public transportation networks for differences, the research unveiled that the city of Munich has a more advanced and modern public transportation system than the city of Boston. To convince companies and employees in Boston to increase their usage of the public transportation system, improvements to the schedule, accessibility, affordability and reliability should be made. A good public transportation system provides immense benefits to the community by improving the environment and quality of life, as well as attracting companies, creating jobs and increasing tax incomes.Geograph
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
Which Urban Residents Vote and Why? A Geospatial Analysis of Voting Behavior in Worcester, MA
Get PDFThis study investigates the relationship between voter travel distance to polling places in Worcester, MA and voter turnout. Linear and geographically-weighted regression are used to evaluate the significance of travel distance and demographic control variables. Worcester appears to be unique when compared to previous studies investigating travel distance and voter turnout. Travel distance to polling place does not reliably predict voter turnout in Worcester, but vehicle ownership, race, and age do.Geograph
Bicycle Infrastructure And Accessibility In Boston’s Environmental Justice Communities
Get PDFThis project focused on bicycle infrastructure in Boston, including the city's count of bicycle infrastructure and cycling accessibility. Infrastructure included Bluebike stations from November 1st, 2023, and bicycle trails from the 2020 MassDOT Bike Inventory. Accessibility explored the gaps in Boston's bicycle infrastructure in environmental justice (EJ) 2020 census block groups. As of the 2020 Census, 460 of the 581 census block groups in Boston are EJ designated, meaning that approximately 79.17% of census block groups are EJ designated. 2020 EJ designated census block groups' count of bicycle infrastructure and their accessibility to bicycle infrastructure in Boston, MA were analyzed in ArcGIS Pro using spatial joins, distance accumulation, and a suitability modeler. The average number of bicycle trails in a 2020 EJ census block group was 4.22, while the average number of Bluebike stations in a 2020 EJ census block group was less than 1 (0.465). Bicycle lanes were the most common bicycle trail type across the EJ designated census block groups, but 139 (30.22%) of the EJ 2020 census block groups had zero bicycle trails, showcasing a need for bicycle trail connection in these areas. More than the majority, or 302 (65.65%), of EJ designated census block groups had 0 Bluebike stations as of November 1st, 2023. Accessibility to bicycle infrastructure was highest in the neighborhoods surrounding Downtown, such as the North End, West End, Beacon Hill, Back Bay, Fenway, South End, Chinatown, and the South Boston Waterfront. Accessibility was more varied elsewhere, particularly in the West Roxbury, Hyde Park, Brighton, Dorchester, Roxbury, Jamaica Plain, Mattapan, and Roslindale neighborhoods. Bicycling is an essential aspect of multimodal transport and should be constantly evolving and improving.Geography and Sustainabilit
A Whale Of A Good Time: Whale Watches Spreading Conservation Through Education
Get PDFEcotourists are more concerned with their impact on the environment compared to mainstream tourists. They have a strong commitment to preserving nature and look for educational experiences. These values and motives translate into the activities ecotourists choose to participate in while vacationing. Understanding ecotourist behavior is important, so that destination managers can better market their sites or activity. For example, whale watching is increasing in popularity. Whale watches are a good way to incorporate ecotourist values and help further the conservation of whales. Studies have shown whale watches have an educational component that satisfies visitor expectations. If people are satisfied with the experience, they are more likely to pass on the conservation related information they learned and get their peers to undergo a similar trip. This research project is a literature review of the history of whale watching, motivations of ecotourists, and case studies of whale watches in different areas. In addition to the literature review, I went on a whale watch tour in Cape Ann, Gloucester to see how tours on the North Shore of Boston compare to the case studies. The conclusions in this research project are important as they can be applied to any whale watch to improve visitor satisfaction and better incorporate ecotourist values.Geograph
