Cancers of the intestine, liver, and biliary tract
No full textColorectal cancer is an important cancer worldwide, whose etiology is not fully understood. Known causes include several genetic factors, overweight/obesity, tobacco smoking, and heavy alcohol drinking. An etiologic role of diet is highly plausible, but the evidence for specific factors, with the possible exception of processed meat, is not conclusive. Workers exposed to asbestos have been found at increased risk of colorectal cancer in several studies, but the evidence is not sufficiently strong to conclude in favor of a causal association. No other occupational factors have been linked to colorectal cancer. Liver cancer is a common cancer in many regions of the world and is the second cause of cancer-specific mortality. About 75 % of livercancers are hepatocellular carcinoma (HCC), the second most frequent type being cholangiocarcinoma (CCA). HCC develops in the context of a web of interactions between viral (HBV, HCV), environmental (alcohol, aflatoxin), and metabolic (fatty liver disease, obesity) factors. Genetic predisposition accounts for only a small fraction of the global burden of HCC. The only established occupational cause of liver cancer is vinyl chloride, which causes a rare type of neoplasm, angiosarcoma, and has also been associated with HCC. Detection and diagnosis of HCC are complicated by its occurrence in a background of chronic liver disease characterized by inflammation and cycles of hepatocyte proliferation and destruction. Markers used in clinical practice include serological and molecular markers of viral hepatitis, enzymatic tests for liver function and injury, and a growing list of plasma-based tumor markers, the current gold standard being alpha-fetoprotein (AFP). Recent research has identified molecular changes in transcriptome, microRNAome, epigenome, and, significantly, plasma proteome that pave the way to the development of a new generation of biomarkers for early detection of HCC in different etiologic contexts. © Springer-Verlag London 2014

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
Spectroscopic (analytical) approach to gunshot residue analysis for shooting distance estimation: a systematic review
No full textPublished online: 16 November 2021Background: The determination of the shooting distance using gunshot residue (GSR) analysis is crucial in the investigation and reconstruction of firearm-related crimes. However, the conventional chemographic method for GSR analysis is destructive and has limited sensitivity and selectivity. While the spectroscopic method has potential in GSR analysis for crime investigation, there is a current lack of consistency in the spectroscopic results obtained for shooting distance estimation via GSR analysis. Addressing such limitations will enhance the forensic capabilities of law enforcement and provide an added advantage to crime laboratories during an investigation. It will also reinforce the use of such spectroscopic data in a criminal investigation. Main text: We obtained all peer-reviewed articles relevant to shooting distance estimation from searching Scopus, Web of Science, PubMed, and Google Scholar databases. We specifically searched the databases using the keywords “shooting distance,” “range of fire,” “gunshot residue,” “firearm discharge residue,” and “firearm-related crime” and obtained 3811 records. We further filtered these records using a combination of two basic keywords “gunshot residue” and “shooting distance estimations” yielding 108 papers. Following a careful evaluation of the titles, abstracts, and full texts, 40 original peer-reviewed articles on shooting distance estimation via GSR analysis were included in the study. The forgoing included additional sources (n = 5) we obtained from looking through the reference lists of the forensic articles we found. Short conclusion: This paper discusses the current scope of research concerning the chemographic and spectroscopic analysis of GSR for shooting distance estimation. It also examines the challenges of these techniques and provides recommendations for future research.Maxwell Abedi, Dan O. M. Bonsu, Isaac K. Badu, Richmond Afoakwah and Pooja Ahuj
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
