ABSTRACT This paper aims to paint portraits of international authors contributing to journals in China and to analyse the relationship between these authors and journals. An international authorship is crucial to the academic quality and global influence of journals. This study integrates bibliometric analysis with academic portrait methods. It employs the Boston Consulting Group (BCG) growth‐share matrix to identify and label critical dimensions of international authors' research. The findings indicate that scholars from the United States, India, Japan, Germany, Australia and other countries are the main international contributors to journals in China. These authors present unique characteristics in terms of quantity, collaboration, influence, loyalty and quality. The characteristics of scholars from these countries/regions in terms of dimensions such as research areas, open access, funding sources and Sustainable Development Goals are also analysed.

PurposeThis paper aims to make a comprehensive evaluation of the progress and achievements made by China and Japan in literature collection, publication and academic research of South Manchuria Railways Co (SMR) after the Second World War and points out the existing and urgent problems.Design/methodology/approachThis paper adopts the methods of literature research, questionnaire survey, comparative analysis and expert consultation.FindingsAfter the Second World War, both China and Japan made great achievements in the collection, publication and research of SMR data, as well as in the academic research of SMR. However, as a new research field, there are still some problems in deepening the excavation and utilization of SMR data, expanding the research fields, improving the research methods, etc.Originality/valueSMR itself was the product of a war of aggression. Although it died with the defeat of the war of aggression, remaining SMR data also has very precious value, it records the history of Japanese aggression against China, is the biggest database for the study of the problems in China and northeast Aisa at that time. In addition to Japan and China, the USA and the Soviet Union also kept part of the SMR data, so that to involve them in the research of SMR is also the purpose of this paper.

To the Editor: As we have known, Emergency Medicine is an interdisciplinary subject and has many hot spots for research. However, many researchers often worry that their research is too narrowed or not so cutting edge as to be accepted by journals with high impact factor (IFs). Why? One reason perhaps lies in the fact that many of them have difficulty in following the fronts and hot spots in internal Emergency Medicine research. Here, we introduce the use of Essential Science Indicator (USA) tools to analyze the frontier and cutting edge researches in the field of internal Emergency Medicine, and we hope this can help researchers in finding research fronts. The 5 hotspots of internal Emergency Medicine research were “sepsis,” “acute pulmonary,” “trauma,” “shock” and “cardiopulmonary resuscitation.” Yes, sepsis is the hottest subject in Emergency Medicine. Although there are already some large studies published in top medicine journals about Surviving Sepsis Campaign Protocols (SSCP),[123456] SSCP is still the hottest front for years to come. The followed hotspots are acute lung injury; the most attention were paid on the acute respiratory distress syndrome, receptor signaling, and acute lung injury evaluation. And others can refer to the Table 1.Table 1: The keywords and fronts of internal Emergency Medicine research

Peer-to-Peer (P2P) systems have proved to be the most effective and popular file sharing applications in recent years. Previous studies mainly focus on the equal service and the differentiated service strategies when peers have no initial data before their download. In an upload-constrained P2P file sharing system, we model both the equal service process and the differentiated service process when peers' initial data distribution satisfies some special conditions, and also show how to minimize the time to get the file to any number of peers. The proposed models can reveal the intrinsic relations among the initial data amount, the size of peer set and the minimum last finish time. By using the models, we can also provide arbitrary degree of differentiated service to a certain number of peers. We believe that our analysis process and achieved theoretical results could provide fundamental insights into studies on bandwidth allocation and data scheduling, and can give helpful reference both for improving system performance and building effective incentive mechanism in P2P file sharing systems.

The China-US Million Book Digital Library Project (MBP) is a cooperated project of universities and institutes in China and USA, with funding from the Ministry of Education of China (MOE) and National Science Foundation of USA (NSF). The objective of MBP is to create a free-to-read, searchable collection of one million books, available to everyone over the Internet. This task will be accomplished by scanning the books and indexing their full text. Based on the plan and experience in MBP, six technical issues are presented in this paper, such as content selection, copyright clearance, data production, metadata creation, digital preservation and access, and quality control. The current status of the project and the future plan are discussed.
