Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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

Abstract 5625: Molecular and immunologic characterization of HRAS mutations in a cohort of 6,329 patients with cutaneous melanoma
Background: Activation in RAS pathway has been associated with cancer development. Three RAS family members, including NRAS, KRAS and HRAS are frequently mutated across various cancer types, where NRAS mutations are present in 15-20% of melanomas. NRAS-mutant melanomas (NRASm) have been extensively characterized. However, molecular and clinical implications of HRAS mutations (HRASm) in melanoma are less well understood.
Methods: A total of 6329 melanoma samples were subjected to comprehensive molecular profiling at Caris Life Sciences. Analyses included next generation sequencing of DNA (592 Gene Panel, NextSeq; whole exome sequencing, NovaSEQ), RNA (NovaSeq, whole transcriptome sequencing, WTS) and IHC. MPAS scores to evaluate MAPK pathway activation, IFN scores, QuantiSeq, neoantigen load (high, intermediate, low binding affinity: HBA, IBA and LBA) and GSEA were calculated from mRNA expression data. Wilcoxon, Fisher’s exact were used to determined statistical significance (p value without and q value with multi comparison correction; FDR for GSEA). The reference cohort was the entire melanoma cohort (MC).
Results: HRASm were identified in 69 (1.09%) of melanoma samples (hotspots mutations: G13, 40%; Q61, 34%; G12, 18% and others, 9%). HRASm and NRASm had different genomic landscapes: HRASm were significantly associated with a higher mutation rate of NF1 (43.2% vs 27.7%, p<.05), ARID1A (17.2% vs 6.3%, p<.05), B2M (14.3% vs 2.4%, p<.05), RAF1 (12.2% vs 1.4, p<.0001), CTNNB1 (9.1% vs 3.3%, p<.05) and higher amplifications of EMSY (11.8% vs 1.8%, p<.01), MRE11 (4.3% vs 0.5%, p<.05), whereas NRASm harbored less NF1 (14.8% vs 27.7%, q<.0001 ), BRAF (6.9% vs 39.9%, p <.0001), PTEN (3.9% vs 6.9%, q <.05), KIT (0.8% vs 4.4%, q <.0001) mutations and less amplification PDGFR (0.4% vs 1.3%, p<.05), BRAF (0.2% vs 1.4%, p<.05), KIT (0.2% vs 2.1%, q<.05) when comparing to MC. Both HRASm and NRASm had higher MPAS scores than MC (HRASm, 0.24; NRASm, 0.11; MC, -0.41, q<.001). In addition, HRASm showed higher TMB (HRASm, 68.1%; NRASm, 56.9%; MC, 50.0%, q<.05), relatively higher IFN scores (HRASm, 0.16; NRASm, -0.23; MC, -0.24, q = .16) and higher neoantigen load (HBA: HRASm, 10.5; NRASm, 4; MC, 4, p < .05; IBA: HRASm, 17.5; NRASm, 8 MC, 7, p < .05; LBA: HRASm, 37.5; NRASm, 21; MC, 19, p =.1) when compared to NRASm and MC. Lastly, suppression of angiogenesis pathway was observed in both HRASm (NES = 1.7, FDR<.05) and NRASm with respect to MC (NES = 1.4, FDR<.25).
Conclusions: The genomic landscape of HRASm are significantly different from that of NRASm, implying their distinct roles in tumorigenesis. HRASm also demonstrated higher MAPK activation, suggesting that they could potentially benefit from agents targeting on this pathway. In addition, HRASm displayed more immunogenic features, associated with down-regulation of angiogenesis pathway, revealing a potential higher susceptibility of HRASm to immunotherapy.

Dispelling the Myths Behind First-author Citation Counts
We 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
Charitable giving: the effectiveness of a revised theory of planned behaviour model in predicting donating intentions and behaviour
This is the author's post-print version of an article whose final and definitive form has been published in Journal of Community & Applied Social Psychology. Copyright © 2007 John Wiley & Sons, Ltd. The definitve version is available at: http://www3.interscience.wiley.com/journal/5625/homeA revised theory of planned behaviour (TPB) model was used to determine the influence of attitudes, norms (injunctive, descriptive and moral norms), perceived behavioural control, and past behaviour on intentions to donate money to charitable organisations. Respondents (N?=?227) completed a questionnaire assessing the constructs of the revised TPB model. Four weeks later, a subsample of respondents (N?=?67) reported their donating behaviour. Hierarchical multiple regression analyses revealed support for the revised TPB model. Attitudes, perceived behavioural control, injunctive norms, moral norms and past behaviour all predicted charitable giving intentions; however, descriptive norms did not predict donating intentions. Donating intentions were the only significant predictor of donating behaviour at Time 2. In addition, a number of beliefs differentiated between those who did and did not intend to donate to charity. Theoretical and applied implications of the results are discussed
koamabayili/VECTRON-author-checklist: VECTRON author checklist
We 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
