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
Role of financial development in economic growth: a case study of Pakistan
No full textPakistan has made remarkable efforts to transform its financial system since 1990s. After the introduction of the market based policy reforms in 1990, Pakistan’s financial system has experienced significant changes including privatization of public sector banks, public sector enterprises, introducing Islamic banks, Microfinance Banks, increased role of non-bank financial institutions including stock market, Insurance sector etc. and issuing license to new private banks. After reforms process started, Role of private financial institution increased specially role of commercial banks, as still today Commercial Bank play major intermediary role between lenders and borrowers in Pakistan. In case of Pakistan, previous studies focused on the aggregate data of financial sector to determine the connection between Financial Development and Economic Growth. In this project, empirical analysis is performed using annual data of Loans given to different sectors as a proxy of Financial Development for the period from 1974 to 2010. The results of Co-integration test suggest one co-integrating equation for the sectors including agriculture-etc, Commerce and Trade, Construction, Manufacturing and M2. All other sectors including Mining, Utilities, Transport Etc, Services and Other loans have no Co-integration relationship with GDP Growth in Pakistan. The justification of the result is that major chunk of the total commercial loans in Pakistan goes to manufacturing, commerce and trade and construction while an agricultural sector gets subsidies which are equivalent to the loan. Other sectors depends more on informal loans etc. I have used the Granger-causality test procedure under vector autoregressive model to determine the relationship between economic growth and Loans given to different Sectors. The analysis provided evidence that presence and direction of causality is affected by different sectors. One way causality existed for four sectors including FDI, Commerce and Trade, Services, Mining and M2 suggesting that GDP Growth granger causes FDI, Commerce and Trade, Services, Mining and M2. Reason for non-existence of causality between economic growth and financial development may be that privatization effect is yet to takeoff. It has inadequate to expect the effect of Privatization on GDP. It may be due to factors like, still our economy is more informal. A large no of people still do not access banks for financial services in Pakistan. Other factors include discontinuation of policies at National level, NPLs, power crisis, terrorism etc which leads to capital flight. However, to sustain the growth it is important to further remove market imperfections, access to those communities which ado not access banks, access of Islamic Banking services in small cities and towns, develop market based credit allocations and no rationing of credits and improve access to financing for private as well as small and medium-sized enterprises
Exploration de l'espace de conception de processeurs via simulation accélérée
No full textSimulation is a vital tool used by architects to develop new architectures. However, because of the complexity of modern architectures and the length of recent benchmarks, detailed simulation of programs can take extremely long times. This impedes the exploration of processor design space which the architects need to do to find the optimal configuration of processor parameters. Sampling is one technique which reduces the simulation time without adversely affecting the accuracy of the results. Yet, most sampling techniques either ignore the warm-up issue or require significant development effort on the part of the user.In this thesis we tackle the problem of reconciling state-of-the-art warm-up techniques and the latest sampling mechanisms with the triple objective of keeping the user effort minimum, achieving good accuracy and being agnostic to software and hardware changes. We show that both the representative and statistical sampling techniques can be adapted to use warm-up mechanisms which can accommodate the underlying architecture's warm-up requirements on-the-fly. We present the experimental results which show an accuracy and speed comparable to latest research. Also, we leverage statistical calculations to provide an estimate of the robustness of the final results.Nous nous focalisons sur l'échantillonnage comme une technique de simulation pour réduire le temps de simulation. L'échantillonnage est basé sur le fait que l'exécution d'un programme est composée des parties du code qui se répètent, les phases. D'où vient l'observation que l'on peut éviter la simulation entière d'un programme et simuler chaque phase juste une fois et à partir de leurs performances calculer la performance du programme entier. Deux questions importantes se lèvent: quelles parties du programme doit-on simuler? Et comment restaurer l'état du système avant chaque simulation? Pour répondre à la première question, il existe deux solutions: une qui analyse l'exécution du programme en termes de phases et choisit de simuler chaque phase une fois, l'échantillonnage représentatif, et une deuxième qui prône de choisir les échantillons aléatoirement, l'échantillonnage statistique. Pour répondre à la deuxième question de la restauration de l'état du système, des techniques ont été développées récemment qui restaurent l'état (chauffent) du système en fonction des besoins du bout du code simulé (adaptativement). Les techniques des choix des échantillons ignorent complètement les mécanismes de chauffage du système ou proposent des alternatives qui demandent beaucoup de modification du simulateur et les techniques adaptatives du chauffage ne sont pas compatibles avec la plupart des techniques d'échantillonnage. Au sein de cette thèse nous nous focalisons sur le fait de réconcilier les techniques d'échantillonnage avec celles du chauffage adaptatif pour développer un mécanisme qui soit à la fois facile à utiliser, précis dans ses résultats, et soit transparent à l'utilisateur. Nous avons prit l'échantillonnage représentatif et statistique et modifié les techniques adaptatives du chauffage pour les rendre compatibles avec ces premiers dans un seul mécanisme. Nous avons pu montrer que les techniques adaptatives du chauffage peuvent être employées dans l'échantillonnage. Nos résultats sont comparables avec l'état de l'art en terme de précision mais en débarrassant l'utilisateur des problèmes du chauffage et en lui cachant les détails de la simulation, nous rendons le processus plus facile. On a aussi constaté que l'échantillonnage statistique donne des résultats meilleurs que l'échantillonnage représentati
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
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
