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
A REVIEW ON OBSERVATION OF URBAN HEAT ISLAND IN THERMAL REMOTE SENSING
Get PDFThe climate experts have proposed various approaches and strategies to understand the causes of Urban Heat Island (UHI) phenomenon. The aim of this paper is to review the details concerning the themes of urban climate study and its measurement over a variety of cities. The paper discusses several approaches of thermal remote sensing study of different spatial resolution as well as satellite images. The researchers conclude with the development of an observation framework of the thermal remote sensing
Spatial statistical analysis of dengue cases in Shah Alam / Illyani Ibrahim
Get PDFDengue fever one of the most dangerous and contagious tropical diseases has become an enormous problem. It has now become a public health concern. One of the ways of controlling the disease is by taking stern action against the disease. Therefore, this research is undertaken to analyse the widespread of dengue by integrating Geographical Information System (GIS) into spatial statistical analysis. The aim of this research is to study the spatial pattern of dengue cases in the Petaling District of Selangor. Using data on dengue cases reported in the locality in 2003 and 2004, current dengue cases are analysed. A new approach is proposed to include monitoring of dengue surveillance, the spatial distribution of the dengue occurrence by using GIS, and examining the spatial pattern of dengue distribution by using spatial statistical analysis. In evaluating and controlling current dengue events, the study utilises on information provided by officials of the health authority by way of personal interviews as well as scrutinising official records on surveillance and prevention activities including work procedures. The descriptive statistics are used for analyzing spatial distribution. Several techniques are used to identify cluster are nearest neighbour analysis, detection cluster analysis, spacetime analysis, density and hotspot analysis and space-time outbreak investigation. With better information on disease onset, mosquito breeding sites, clusters of breakout, among others, the authority is able to develop a better and more effective surveillance and control programmes to mitigate the threat of dengue, not only in the study area but in nearby areas. Analysis of geographical distribution of the dengue cases provides quantitative data on victims by gender, age, location and land use. It has provided visual representation of actual cases. The result shows that male residents aged 13 to 24 are more likely to be infected by dengue than the other members in socio-demographic groups. The analysis has identified areas (sections) in Shah Alam that are seriously infected in 2003 and 2004. For 2003 and 2004, the clustered areas are Section 9, Section 24, Section 18, Section 16 and Section 20. Considering the total of population and the number of cases, the clustered areas are Section 18 and Section 17. The space-time analysis reveals that the critical time in dengue outbreak is ten (10) days and it affects those residing in areas within 400-meter radius of the first incidence. This information suggests that fogging work should be performed at least weekly to cover the affected areas. In conclusion, the study recommends that the health authority maintains timely and accurate records of dengue cases, giving particular attention to each patient’s travel history during the one weak prior to contracting the disease. It also recommends that GIS be used in surveillance and control works as explained in this study
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
Traditional compactness of the urban core: ‘walkability’ and the Malay public realm
No full textThis chapter focuses on identifying the intimacy and compactness in the public spaces of a part of South East Asia’s urban cores. The traditional South East Asia urban cores are the centres of traditional settlements before the disruption due to colonialism. The traditional character has disappeared along with modern urbanisation. This chapter includes three case studies: Alor Setar, Kuala Terengganu, and Kota Bharu. The case studies describe the compactness from the perspective of walkability and liveability of the traditional urban core and the settlement areas. The chapter also suggests that the character of compactness between the royal elements persists over time
