Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
BHAC-MRI: Backdoor and Hybrid Attacks on MRI Brain Tumor Classification Using CNN
No full textDeep learning (DL) models have demonstrated impressive performance in sensitive medical applications such as disease diagnosis. However, a backdoor attack embedded in the clean dataset without poisoning the labels poses a severe threat to the integrity of Artificial Intelligence (AI) technology. In literature, a lot of work has been done on backdoor attacks for medical applications, in which most of the authors assumed that the labels of the samples are also poisoned. This compromises the elusiveness of the backdoor attacks because poisoned samples can be identified by visual inspection by finding the mismatch between the labels of the samples. In this paper, an elusive backdoor attack is proposed, that makes the poisoned samples difficult to recognize. In the proposed approach a backdoor signal superimposed into a small portion of the clean dataset during training time is proposed. Moreover, this paper proposes a hybrid attack that further increases the Attack Success Rate (ASR). The proposed approach is evaluated over a Convolutional Neural Network (CNN)-based system for Magnetic Resonance Imaging (MRI) brain tumor classification, which demonstrated the effectiveness of the attacks, thus raising concern regarding using AI in sensitive applications
DAMPAK REVITALISASI PASAR TERHADAP PENINGKATAN PENDAPATANPEDAGANG DI PASAR ANDI TADDA KOTA PALOPO
Full text linkABSTRAK
Imran M, 2023. “Dampak Revitalisasi Pasar terhadap Pendapatan Pedagang di
Pasar Andi Tadda Kota Palopo” Skripsi Program Studi Ekonomi Syariah
IAIN Palopo. Dibimbing oleh Ilham, S.Ag., M.A.
Skripsi ini membahas tentang Dampak Revitalisasi Pasar terhadap Pendapatan
Pedagang di Pasar Andi Tadda Kota Palopo. Penelitian ini bertujuan: untuk
mengetahui Dampak Revitalisasi Pasar terhadap Pendapatan Pedagang di Pasar
Andi Tadda Kota Palopo. Jenis penelitian ini menggunakan pendekatan Kualitatif
deskriptif. Penelitian ini dilakukan dengan melibatkan pedagang sebagai informan
pada tanggal 9 sampai 16 Juli 2023 dengan jumlah Informan sebanyak 11 orang
yakni 8 orang pedagang yang mana pedagang tersebut mulai berdagang dari sebelum
adanya revitalisasi sampai sesudah dilakukan Revitalisasi dan 3 pihak pengelola
Pasar. Setelah mengalami revitalisasi, pasar menjadi lebih bersih, rapi dan tertib yang
berdampak terhadap peningkatan pembeli. Setelah adanya revitalisasi di Pasar
tradisional pendapatan para pedagang mengalami peningkatan. para pedagang
menyatakan bahwa revitalisasi meningkatkan volume penjualan mereka. Hal ini
disebabkan karena kondisi bangunan dari pasar tradisional telah mengalami
perubahan yang lebih baik. Perubahan tersebutlah yang menarik minat para
pengunjung untuk berbelanja ke pasar tradisional dan meningkat volume penjual
para pedagang di Pasar tradisional.Dari segi keuntungan, para pedagang di Pasar
Andi Tadda Palopo menyatakan setelah adanya revitalisasi keuntungan mereka
meningkat. Hal ini disebabkan karena kondisi pasar yang selalu ramai oleh
pengunjung dan penjualan mereka semakin meningkat. Berdasarkan 2 indikator yang
telah dijelaskan diatas yakni penjualan dan keuntungan, secara tidak langsung
gambaran dari penghasilan pedagang dapat dilihat. Ketika volume penjualan
meningkat, keuntungan juga meningkat maka hasil akhirnya adalah peningkatan
penghasilan

Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
