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
Untersuchung der Hangstabilisierung mittels Bodenvernagelung in Nepal : Auswirkung Niederschlagsereignisse
No full textDiese Masterarbeit untersucht die Anwendung der Bodenvernagelung als Methode zur Hang- und Böschungssicherung in Nepal, insbesondere in Regionen mit häufigen Starkregenereignissen. Aufgrund des Monsunklimas und der intensiven Landnutzung zählen die gebirgigen Regionen Nepals zu den weltweit instabilsten Landschaften, die von Naturgefahren wie Erdrutschen, Muren und Bodenerosion bedroht werden. Nepal, eines der am wenigsten entwickelten Länder (LDC), hat begrenzte finanzielle Mittel, um teure Sicherungsmaßnahmen zu finanzieren. Daher werden kostengünstige, aber arbeitsintensive geotechnische und ingenieurbiologische Bauweisen bevorzugt. Im Fokus der Arbeit steht die Untersuchung des Krismer®-Systems zur Bodenvernagelung. Dieses Verfahren zeichnet sich durch seine Fähigkeit aus, hohe Reibungswiderstände zu erzeugen, da die Nägel direkt ohne Zement in den Boden geschlagen werden und flächige Profile aufweisen. Zudem wird auf die übliche Spritzbetonsicherung verzichtet; stattdessen kommt ein dreidimensionales Gitter, verfüllt mit Kantkorn als Flächendrainage, Erde und Saatgut zum Einsatz, das durch die Bodennägel gehalten wird. Diese Methode fördert die langfristige Stabilität der Böschung und ist besonders in regenreichen Regionen vorteilhaft. Ein Feldversuch an einem Hang entlang des Kathmandu-Terai Expressways wurde durchgeführt, um die Eignung des Systems unter realen Bedingungen zu prüfen. Im Labor wurden geotechnische Untersuchungen und 2D-Finite-Elemente-Modellierungen vorgenommen, um den Einfluss von Niederschlägen auf die Standsicherheit zu simulieren und die Anwendbarkeit der Bodenvernagelung in Nepal zu evaluieren. Die Ergebnisse zeigen, dass das Krismer®-System durch seine spezifische Konstruktion und einfache Umsetzbarkeit eine kostengünstige Alternative für die Hangstabilisierung in Nepal darstellt.The master's thesis examines the application of soil nailing for slope stabilization in Nepal, particularly in regions with frequent heavy rainfall. Due to the monsoon season and intensive land use, the mountainous regions of Nepal rank among the world's most unstable landscapes, threatened by natural hazards such as landslides, mudslides, and soil erosion. Nepal, as one of the Least Developed Countries (LDC), has limited financial resources to fund expensive stabilization measures. Therefore, cost-effective yet labor-intensive geotechnical and bioengineering methods are preferred. We focus on the suitability of the Krismer® soil nailing system. The Krismer system is characterized by easy handling with high friction resistance, as the nails are driven directly into the ground without grouting. Additionally, the conventional shotcrete surface protection is not used. Instead, a three-dimensional grid filled with crushed stone as a surface drainage layer, held in place by the soil nails. Combined with soil and grass seeds, this system offers ideal condition for vegetation. This method enhances the long-term slope stability and is particularly attractive in regions with heavy rainfall. A field test was conducted on a slope along the Kathmandu-Terai Expressway to assess the system's suitability under real-world conditions. Laboratory tests and 2D finite element modelling were also carried out to simulate the impact of rainfall on slope stability and evaluate the applicability of soil nailing in Nepal. The results show that the Krismer® system, due to its specific construction and straightforward implementation, presents a cost-effective alternative for slope stabilization in Nepal.verfasst von Samuel SchnarchMasterarbeit BOKU University 2024Mit englischer Zusammenfassun
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

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
The Effect of Superfund on Post-Industrial Communities: An Analysis of Geographic Identity
No full textThe interactions between people and place have long been understood as producing an integrated dialogue between them. The forcommunicated paper deals the impact of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), or Superfund, on local communities and their sense of place in southwest Colorado.
A literature review of relevant research was conducted, revealing the economic impacts of Superfund (mean 4 - 16.26% depreciation in property values) via hedonic regression analysis. Studies of the impact of outside stigma also demonstrated the endemic capacity of negative, outside outlooks to exacerbate the challenges of post-industrial development. Case studies were also gathered from other sources, covering the sequence of events in Toluca, Illinois; Cokedale, Colorado; Picher, Oklahoma; and Berlin, North Carolina. Common trends were observed in the recounting of said case stories that impacted the evolution of their geographic identity in dealing with site designation and remediation proceedings. Trends included the homogeneity of sense of place, community involvement in remediation efforts, existing alternative economic development, motivation on the part of the government itself, and a community’s ability to cope with and combat outside stigma.
These trends were then used to generate a case study of superfund proceedings in Durango, Colorado, and the remediation of the “Smelter” site, the location of the leftover tailings of the Vanadium Corporation of America. A predictive discussion was then undertaken with regards to the future remediation of the Bonita Peak Mining District, a newly listed site near Silverton, Colorado. In the cases of both Durango, and Silverton, there was observed to be high levels of community involvement and alternative exploration, namely into tourism, which suggests a positive ultimate outcome in each case. The final impact on Silverton’s sense of place, however, would seem to depend upon the community’s desire and ability to retain the artifacts of their hard-rock mining heritage, and to what extent they prove successful at doing so
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
