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
Advanced Chemical Industries’ Shwapno Initiative: A Bridge Between Farmers and Urban Consumers
No full textMr. Asif Iqbal, Chief Operating Officer of Shwapno (brand name of Advanced Chemical Industries (ACI) Logistics Limited, a subsidiary of ACI), stood at the window of his Dhaka office one afternoon of January 2010. He had just returned from a meeting in which ACI’s Chairman, Managing Director, Executive Director (Agri-businesses), and Executive Director (Consumer Brands) had announced that Shwapno, a chain of 32 retail outlets, would expand by more than 100 countrywide retail outlets by January 2011, to address everyday household needs of consumers.
This news greatly pleased Mr. Iqbal, who had been one of the creators of the Shwapno supply-chain concept. As car horns blared in consistent cacophony outside his office, Mr. Iqbal envisioned the Shwapno outlets that would collect fresh materials from rural areas, far removed from the streets of Dhaka. Millions of farmers scattered across Bangladesh spent their days in doubt as to whether they could sell their products at a fair price, or at all, even if they had bumper production in their fields. Most of the farmers, fisherman, and meat producers of the country were victim to typical interest business Dadan, a business system in Bangladesh in which middlemen purchase produce from farmers at a low price and sell it at a high price to consumers. Lots of vegetables grew moldy in rural areas, because farmers did not find enough buyers who would buy their goods, whereas city dwellers paid extra to meet their vegetable needs. Additionally, poor transportation infrastructure contributed to inefficient flow of agricultural goods from rural to urban areas.
Producers were on one extreme end of the value chain, and consumers were on the other extreme. A shopper in an urban area often lost his or her interest in shopping in the market, due to untidy ambiance, such as muddy floors, insufficient space to move, unhygienic arrangement of products, the bargaining process, and inconsistent pricing. Even though the market was flooded with a wide range of products, a large portion of the population, especially farmers and end-users, were deprived of an efficient and convenient retail process. Producers did not get appropriate prices for their production and consumers invariably were deceived by sellers, who often sold inferior goods, inaccurately measured goods, and so on.
Understanding this gap in the value chain, ACI had initiated to establish a new business, namely Shwapno, to eliminate the gap, uproot the cartel, and ensure reasonable prices for both farmers and consumers. The objective of this subsidiary was to engage in the business of buying, selling, importing, and exporting of agri-products directly to consumers. The company, a unit of ACI Group, claimed that the venture would also ensure fair prices for farmers, who often got poor returns on their yields, mainly due to market manipulation. The ACI’s business decision to add at least 100 retail outlets throughout the country over the year would bring a number of challenges. Mr. Iqbal and his team would need to decide how to procure produce and create a viable strategy to build outlets.Full Tex
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
Factors Influencing Bike Purchase Decisions: A Study of Consumers in Bangladesh
No full textBangladesh is an emerging market of motorbikes. Here, poor infrastructures, highly income variation of people, large family members, different uses of bikes, and finally the emerging market of bikes stimulate the need for studying about bike users. Thus, the study is designed to take part the theoretical understanding of homogeneity of Bangladeshi consumers and its impact on bike purchasing. The results should assist marketers to know the common traits of Bangladeshi consumers who consider these in buying bikes. A conceptual homogeneity framework has been examined through the SEM with workable questionnaires. So results obtained prop up the conceptual framework showing that all consumers consider the factors such as exterior, convenience, performance, safety, economic aspect, attitude to mark, sale service, after sale service, and country of origin in case of bike purchasing. Marketer should, therefore, use the findings for new brand building, brand extension, market extensions of motorbikes in Bangladesh.No Full Tex
Binary and ternary quasifission induced by shell effects at near barrier energy in heavy nuclear systems
Get PDFThe study of the true ternary fission (simultaneous decay in three fragments of similar mass) with formation of a heavy third fragment due to strong shell effects has received new interest among nuclear physicists. It is a very rare
process which has been studied both theoretically and experimentally since several decades, but still it is quite far from proper understanding.
This PhD thesis concerns with the experimental observation of true ternary decay in three reactions. Specifically, at 195 MeV, at 193 MeV and at 193 and 230
MeV reactions were studied at the K130 Cyclotron accelerator of the University of Jyv\ddot{\mbox {a}}skyl\ddot{\mbox {a}}, Finland. The first two reactions populating the same compound nucleus were investigated for possible entrance channel effects, whereas for the last system, , two different bombarding energies have been provided to investigate the effect of excitation energy of the compound system. Four time-of-flight (TOF) arms coupled with six telescopes of silicon detectors and a beam monitoring system constitute the complete experimental setup. Two dimensional velocity coincidence maps were built from TOF arms. The presence of cluster patterns in the two-velocity maps for all the reactions is the main observation of this work. Another outcome of the present investigation is the consistent overlap between the tripartitions that reproduce the data in the companion reactions and , and in the reactions at 193 and 230 MeV. These two findings give support to the occurrence of the simultaneous three-body decay. The comparison between the rate for binary and ternary decays has also been achieved by calculating the ratio of such events corrected for the efficiency. These ratios are quite striking because in spontaneous fission the simultaneous ternary decay is several orders of magnitude less abundant. In the case of and , true ternary fission is even from 2 to 4 times more abundant than binary fission
