Recording systems. GPS satellites for archaeology: surveying around the Puruhuay Lake
No full textThis chapter deals with the various surveying methods that have been applied to the Puruhuay area. For the study of ancient settlement systems, it is essential to integrate archeological, topographic and geodetic applications, which provide essential geographic information for the archeological interpretation of settlement systems. The contribution of surveyors, engineers and geologists within the team of archaeologists increased the amount of data collected during each field campaign. The chapter describes with details the survey carried out by using GPS technology and the maps production obtained by GIS approach
Con una pacarina a la vista: arquitectura como construccion de autoridad alrededor de la laguna de Puruhuay
No full textCommencing in the eleventh century A.D. a series of settlements and ceremonial sites, in close relationship with the Puruhuay Lake and the waterfall “María Jiray” (Acopalca district, Huari, Ancash) were constructed. The majority of these sites have been studied during the archaeological campaigns of the Project «Antonio Raimondi» between 2006 and 2009. The close relationship between the sites is evident not only because they were built during the same period and within a contiguous territory, but also because of the uniform type of architecture. The complex of settlements built around the lake appear as a planned system of control of a natural place; a natural site that is considered an important pacarina even today, and a resource of great importance for the local economy.A partir del siglo XI, en la zona de la laguna de Puruhuay en el distrito de Acopalca (Huari, Ancash), comenzó a construirse una serie de asentamientos y sitios ceremoniales en estrecha relación con la laguna de Puruhuay y la llamada catarata de María Jiray (en las cercanías de la laguna). Casi todos los sitios han sido estudiados en una serie de campañas arqueológicas de la Misión Antonio Raimondi, entre los años 2006 y 2009.
La relación entre estos estudios es evidente no solo por el estrecho vínculo cronológico y espacial, sino por la tipología uniforme de la arquitectura. El sistema de asentamientos construidos alrededor de la laguna aparece como un centro de control planificado sobre un lugar natural, considerado una pacarina de suma importancia hasta la actualidad y, al mismo tiempo, una fuente de recursos de primer orden para la economía local
UAV Photogrammetry and GIS Interpretations of Extended Archaeological Contexts: The Case of Tacuil in the Calchaquí Area (Argentina)
Full text linkThe scope and scientific purpose of this paper focuses on multiscale (aerial and terrestrial) photogrammetry as a support to investigations and interpretations in a multi-component archaeological site located in the Argentinian Cordillera (Calchaquí, Salta), known as Tacuil. Due to its scarce accessibility, as well as long-term problems associated with the interpretation of the visibility of this type of settlement, the use of aerial surveying was combined with the reconstruction of structures and complex soil morphologies by resorting to modern photogrammetric approaches (3D models and orthophotos). This dataset was complemented by a terrestrial survey to obtain extremely high resolution and detailed representations of archaeological features that were integrated in a GIS database. The outcome of photogrammetric surveying was fundamental in supporting the debate on the functionality of the site and his integration in a complex, socially constructed, ancient landscape. Finally, the present paper introduces the first complete map of Tacuil
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
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
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
