Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
No full textThis work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country
Mining e-mail content for author identification forensics
No full textWe describe an investigation into e-mail content mining for author identification, or authorship attribution, for the purpose of forensic investigation. We focus our discussion on the ability to discriminate between authors for the case of both aggregated e-mail topics as well as across different email topics. An extended set of e-mail document features including structural characteristics and linguistic patterns were derived and, together with a Support Vector Machine learning algorithm, were used for mining the e-mail content. Experiments using a number of e-mail documents generated by different authors on a set of topics gave promising results for both aggregated and multi-topic author categorisation

No full textThe study was conducted at the Experimental Garden of the Faculty of Agriculture, Asahan University, Kisaran Naga Village, Kota Kisaran Timur Subdistrict, Asahan Regency, North Sumatra Province with a flat topography and a height of ± 25 m above sea level, with sufficient water sources with sandy clay texture. The study was conducted in April to June 2018. This study was arranged based on Factorial Randomized Block Design (RBD) with two treatment factors and three replications, the first factor was the dose of rabbit feces fertilizer (K) consisting of 4 levels, namely K0 (without treatment), K1 (0.29 kg / plot) , K2 (0.58 kg / plot), and K3 (0.87 kg / plot), and the second fator is NPK BOOS 324 (N) fertilizer consisting of 3 levels namely N0 (control), N1 (10.8 g / plot), and N2 (21.6 g / plot). The results showed that the treatment of rabbit feces fertilizer had a significant effect on the growth and production of purple eggplant plants. The best treatment was at a dose of 0.87 kg / plot (K3) resulting in plant height of 53.26 cm, number of fruit 8.33 fruit, production per plant 1.13 kg and production per plot of 17.00 kg. NPK BOOS 324 fertilizer treatment significantly affected the growth and production of purple eggplant plants. The best treatment was found in the treatment of 21.6 g / plot (N2) resulting in the highest plant height of 53.26 cm, number of fruits of 8.00 fruit, production per plant of 1.00 kg and production per plot of 15.63 kg. The interaction of giving rabbit feces fertilizer and NPK BOOS 324 fertilizer did not show a significant effect on the growth of purple eggplant

Contribuição ao reconhecimento automático de padrões epileptiformes em sinais de eletroencefalograma utilizando análise morfológica
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro Tecnológico, Programa de Pós-Graduação em Engenharia Elétrica, Florianópolis, 2015.A análise do sinal de eletroencefalograma (EEG) pode ser uma importante ferramenta de auxílio à comprovação clínica do diagnóstico de epilepsia. Esta análise é uma verificação visual criteriosa de registros de EEG na busca por uma atividade eletrográfica específica denominada descarga ou padrão epileptiformes. Essa atividade, quando encontrada com determinada frequência, pode corroborar o diagnóstico de epilepsia. No entanto, como os registros analisados normalmente são resultado de longos períodos de monitoramento, a análise do EEG pode ser um processo demorado. Diversos estudos propuseram metodologias ou sistemas para automatizar este tipo de análise, mas apesar dos esforços e relativo sucesso ainda não existe um algoritmo ou sistema para este reconhecimento automático que seja amplamente difundido no ambiente clínico, possua um desempenho de acordo com as necessidades dos especialistas na área e, do ponto de vista técnico, não possua restrição quanto aos dados de entrada. Desta forma, com o intuito de contribuir para o estudo do reconhecimento automático de padrões epileptiformes o presente trabalho descreve uma proposta de metodologia baseada em análise morfológica e inspirada no comportamento dos especialistas humanos. A análise morfológica é realizada utilizando um conjunto de descritores morfológicos extraídos de sinais de EEG processados digitalmente. A avaliação da metodologia é realizada utilizando um grupo de classificadores computacionais e diferentes bases de dados de EEG. O desempenho da metodologia é analisado por métricas consolidadas na literatura e por uma comparação pareada com o desempenho de sensibilidade, especificidade e concordância de quatro neurofisiologistas clínicos. Resultados obtidos mostraram que o classificador que apresentou o melhor desempenho geral foi uma rede neural combinada com a Análise de Componentes Principais. A sensibilidade e a especificidade média atingida por essa rede foram, respectivamente 58,6 e 87,2%. A eficiência média obtida pela rede nas bases de dados foi de 89%. E a concordância dessa rede com os quatro especialistas foi de 45,7%. Os resultados obtidos para a especificidade mostraram-se satisfatórios, uma vez que os valores médios obtidos foram compatíveis àqueles dos especialistas. Apesar da sensibilidade e da concordância com os especialistas terem apresentado valores baixos, pode-se considerar que a metodologia proposta apresenta resultados promissores considerando a quantidade e natureza dos testes realizados.Abstract : The analysis of the EEG signal (EEG) can be an important support tool to the clinical confirmation of the diagnosis of epilepsy. This analysis is a thorough visual inspection of EEG recordings in the search for a specific electrographic activity called epileptiform pattern or discharge. This activity, when found with a certain frequency, can corroborate the diagnosis of epilepsy. However, as the analyzed recordings are usually the result of long term monitoring, the EEG analysis can be a time consuming process. Several studies have proposed methodologies and/or systems to automate this type of analysis however despite the efforts and relative success, there is still no solution for the automatic recognition that is widely disseminated in the clinical environment, has a performance according to the needs of specialists in the field and, from a technical point of view has no restriction about the input data. Thus, in order to contribute to the study of automatic recognition of epileptiform patterns this work describes a methodology proposal based on morphological analysis and inspired by the behavior of human experts. The morphological analysis is performed using a set of morphological descriptors extracted from digitally processed EEG signals. The evaluation of the methodology is performed using a group of computational classifiers and different EEG databases. The methodology?s performance is analyzed by metrics consolidated in the literature and by a pairwise comparison of the sensitivity, specificity and agreement of four clinical neurophysiologists. Obtained results show that the classifier that presented the best overall performance was a neural network combined with the Principal Component Analysis. The average sensitivity and specificity achieved by this network were respectively 58.6 and 87.2%. The network?s average efficiency obtained in the databases was 89%. And the agreement of the network with four experts was 45.7%. The results for specificity were satisfactory, since the average values obtained were consistent to those of the experts. Despite the low values of sensitivity and agreement with the experts presented by the classifiers, it can be considered that the proposed methodology shows promising results considering the amount and nature of the tests performed in this work
