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

Using Remote Sensing and Geographical Information System To Make Baghdad More Beautiful
Get PDFThe ground of Remote Sensing and Geographical Information System (GIS) has become interesting and attractive with expanding opportunities. It provides critical tools that can be used at various levels to guide decision-making toward long-term sustainability, which in this paper, remote sensing application has used in GIS various fields. These fields such as urban plan city, education, economic development, and natural resource conservation. GIS and remote sensing technology have seen rapid growth over the last decade. This paper presents the most commonly used processing procedures for remotely sensed data, specifically image processing algorithms, as well as the application capabilities of GIS technologies. A study was conducted for the purpose of identify and mapping the temporal variability of land cover types prevalent in Baghdad Governorate using remote sensing and GIS techniques. Because of classified urban areas has increased continuously with time of the shortage and other factors in the category of water bodies over time. For this reason, we first presented processing procedures for remotely sensed data, specifically image processing techniques, as well as the application capabilities of GIS technologies. to reach the develop urban area, given green belt around Baghdad as result, second put the steps of the of urban area plan as show in Figure 1
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
Analysis and Improvement of Geographic Information Systems for Problem Solving and Decision Making
Get PDFThe complexity of our way of life has increased due to the numerous parts of life developing quickly, which results in ongoing issues. To address these issues and respond to these rapid changes in the environment, solutions that were practical, quick, and easy to implement were needed. The use of geographic information tools, a contemporary innovation, allows for the implementation of difficult issues by enhancing users\u27 abilities to comprehend problems thoroughly through the analysis of spatial data and the creation of digital maps. This allows decision-makers to save time, effort, and money by making informed choices that will result in the best possible solution to the issue at hand. In addition to a significant urban expansion, an increase in the number of people using vehicles, and a significant emigration of people from rural and small towns, the traffic jams that have recently engulfed much of the world, particularly in the major capitals and cities, are a result of these factors for transportation, have contributed to a complex problem in modern times. The goal of this study is to examine proposed elements and gauge their impact on the issue of traffic bottlenecks. It then suggests both long- and short-term remedies for this issue based on the study\u27s findings, which are generally not found in the pertinent departments. In order to create a unique surface for these components and provide a comprehensive picture of the research region, it also makes satellite photos of the area available. geographical database for each of them, evaluate each layer\u27s influence on the traffic jam independently by analyzing it, and then merge these levels to create full map that shows their location and the extent to which they affect the study problems. This process was done in order to arrive at the aforementioned solution
Roles of Climate Change and Environmental Sustainability
Get PDFClimate change is widely acknowledged as a major global challenge with serious environmental, economic, and social repercussions. Iraq is ranked as the world\u27s fifth greatest vulnerable country. The country is facing serious challenges, such as rising temperatures, decreasing rainfall, alkalinity, and the latest dust storms. Given this, combating climate change is an urgent and profound task for Iraq, a complex and difficult mission that will span several generations. To confront the challenge of climate change, a comprehensive climate change mitigation and adaptation framework covering as many climate-related topics as possible and connecting as many interested parties as possible across Iraq is required. It is critical to weather patterns topics such as climate-induced impact assessment, environmental vulnerability, and adaptability and sequels, climate change. Our objective use remote sensing and GIS are to mitigation and adaptation strategies to hold the sustainable weather and an improved understanding of climate, climate-related impacts, and remedies
