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
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
Dynamics of cropping land use pattern and status of food scenario in Jammu and Kashmir- a Spatio-Temporal analysis.
Get PDFEconomic activity is the work that people do to enhance their quality of life. Economic activities include all the tasks that people do to get, refine or use natural resources. Land is one important natural resource used by man from times immemorial in a number of ways (Siddhartha, 2008). It was in Neolithic age (10000-2500 B.C.) when man used first time land for cultivation (Dinham, 2003). This practice of care of the soil or the cultivation of land is referred to as „agriculture‟ [Hussain (1970), Varsha and Datye (1976), Mounton (1981), Timmer and Szirmai (2000), Kurosaki (1999), Huffman and Evenson (2001), Misra and Rao (2003), Hayami (2003), Ainsworth and Leakey (2008)] and is by far the most important of the world economic activities. It has been a popular theme of geographic studies in India as well. It is not only because most of the people depend for food and several raw materials on it, but also because of the largest fraction of land under human occupancy is used for agricultural purposes. Therefore, the geographers are primarily concerned with man‟s varied impact upon the earth‟s surface,
i.e., land husbandry or land use analysis (Zamir, 2005). Cropping land-use is a highly dynamic process. It implies that policy discussions and development planning have to be based on a sound understanding of these dynamics. Therefore, it is imperative to make a comprehensive study of the pattern and magnitude of cropping land-use shifts for sustainability and productivity of agriculture in an area (Wani et al, 2009). The very purpose of cropping land use classification is to get an idea of the extent the land has been put into different uses (cereals, non-cereals, cash crops etc). Knowledge of cropping land use helps in maximization of productivity and conservation of land. Physical and human factors influence cropping land use pattern. Cropping pattern refers to the proportion of the area under different crops at a point of time (Siddhartha & Mukherjee, 2007). It also reveals the rotation of crops and the area under double cropping etc. in any state or country.Digital copy of ThesisUniversity of Kashmi
Dynamics of Land use Change in Rural-Urban Fringe - A Case Study of Srinagar City
Get PDFIn the beginning of twentieth century, great scientific inventions like that of
the steam engine had accelerated the process of industrialization. According to urban
geographers, this has provided scope for the expansion of urban centers. Aguilar
(2008), states that, urbanization is one of the most striking human induced land
transformation of the current era. Cities are expanding in size and relative importance
in many parts of the world due to rapid expansion of urban population. Many reasons
have been given for the rapid growth of urban population in the developing countries.
One of the chief causes has been unbridled influx of rural population in to urban
areas. With improved agriculture and increasing pressure of population on land,
surplus rural population is released and pushed out. In the meantime, a pull force on
account of industrialization in urban areas has attracted the potential rural emigrants
to the cities. With rapid pace of industrial development in the towns, progressive
mechanization of the farm, disintegration of the joint family system, and an increasing
demand for men and material in commercial enterprises and public utility services,
the migration of rural population in to urban areas, in search of food and shelter, is
expected to continue unabated. Besides above reasons the attraction furnished by job
opportunities, greater economic insecurity of the adjoining villages, the lure of
improved social facilities for recreation, medical care and education and higher
recreation comfort have also caused the influx of people from rural districts to the
towns. All these factors became responsible for fast growth of urban centers, making
in depth study of urban areas an increasingly important branch of geography
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
