An online electronic journal for teaching purposes

Electronic journals are rapidly increasing in importance as a means of communication, but there is, as yet, little available in the way of training in their production or use. An experimental online electronic journal has therefore been established to provide such training. The journal is provided on the World Wide Web as a distributed activity: in the recently concluded evaluation phase, issues were produced at three nodes ‐ Loughborough University, City University and the University of South Australia. The students involved in the evaluation have been on courses in information, library and publishing studies at both undergraduate and postgraduate levels. The main training topics are: accessing electronic journals and evaluating interfaces; refereeing and editing; evaluating layout and design. The results of the evaluation show that this simulation approach is highly acceptable to students. It also has the value of highlighting areas where students are uncertain, or experience problems in handling the material. Student reactions to, and comments on, electronic journals appear to parallel those among actual users of such journals. Hence the training activity throws some light on the general problems that can be expected in making the transition from printed to electronic journals. As a result of the evaluation activities reported here, an online training package is being assembled, which will be made available over the Internet

Fifty years of UK research in information science

An attempt is made to discern the main research themes in British information science over the past half-century. Within these themes, emphasis is placed on research in the UK that has had some impact on the international information science community. The major factors affecting information research in the UK are also briefly considered

The impact of computer usage on scholarly communication among social scientists

An examination has been made of the effects of using information technology on the communication of research by social scientists in Brazil. Two disciplines were studied – economics and sociology – via both interviews and a questionnaire survey. A small sample of UK social scientists was also interviewed. The results indicate that major changes in communication habits are occurring. These are already well advanced for informal communication and are beginning to appear for formal communication. Differences have been found between economists and sociologists, with the former more active in their use of electronic facilities. Along with such discipline-related differences, the developments also appear to be influenced, in part, by pressures from the research community and from the institutional environment. One significant impact of information technology seems to be an increasing democratisation of the international research community

Os periódicos científicos e a transição do meio impresso para o eletrônico

Publication of scholarly research in electronic form is now commonplace. It is therefore becoming possible to see how electronic publishing differs from print publishing. An analysis of the differences provides some indication of likely trends in the immediate future. A brief discussion of some of the factors as they apply to scholarly journals is presented here. It is concluded that one of the more significant developments will be an increasing diversification of the publishing process.A publicação de pesquisa científica em formato eletrônico é agora lugar comum. Tem se tornado possível ver, portanto, de que maneira publicar eletronicamente difere de publicar em meio impresso. Uma análise das diferenças fornece algumas indicações das tendências possíveis em um futuro imediato. Uma breve discussão da forma como alguns dos fatores se aplicam aos periódicos científicos é apresentada neste artigo. Conclui-se que um dos desenvolvimentos mais significativos será uma crescente diversificação do processo de publicar

Comunicação

Discusses relevant aspects of communication either as a human (social) activity or a topic of sudy. Presents a few comments on the communication process, from the Shannon and Weaver work to nowadays, including changes brought about by the introduction of information technologies onto the communication environment, with special emphasis on organisational environment and communication channels. The author also presents some ideas about communication structuring, particularly regarding scholarly communication, foscusing on the journal article. The discussion also refer to other types of communication. The text ends with a few comments on differences between communication in developed and developing countries. An important list of recommended readings is found at the end.Discute aspectos relevantes da comunicação, tanto em termos de uma atividade social humana, quanto como tópico de estudo. Apresenta alguns comentários sobre o processo de comunicação, desde o trabalho de Shannon e Weaver até os dias atuais, incluindo as mudanças provocadas pela introdução de tecnologias da informação no ambiente da comunicação, com ênfase nos canais de comunicação e no ambiente das organizações. Discute, ainda, algumas idéias sobre a estruturação da comunicação, mais precisamente em relação ao artigo de periódico. Faz referência, também, a outros tipos de comunicação. O texto termina com alguns comentários sobre diferenças na comunicação em países desenvolvidos e países em desenvolvimento. Apresenta, ao final, uma lista importante de textos sobre o tópico

The 5-year Spam: Tracking a Persistent Chinese Influence Operation

This report analyzes the behavior of a single, coordinated inauthentic information operator working within China and in the interests of the Chinese government. This operator has been called by different names by different analysts, including “Spamouflage Dragon“ (by the network analysis firm Graphika) and “Dragonbridge” (by the Google owned cybersecurity firm Mandiant) and has been operating continuously since, at least, April 2017. In this report we will refer to this actor as Dragonbridge. Section II of this report gives an update on several campaign this actor has engaged in recent months. Section III presents a synthetic overview of some of Dragonbridge’s past and ongoing tactics and targets. Section IV draws some more general lessons about how this actor operates

Crypto Bestiary: \u3ci\u3eA monstrous manual to the many fraudulent accounts involved in cryptocurrency scams and fraud.\u3c/i\u3e

Cryptocurrencies have fueled the growth of online fraud in various forms. They are poorly understood by many users, have value that shifts quickly and unexpectedly, and are easy to move in a digital world without borders. Cryptocurrency is seemingly purpose built as a tool for hucksters and scammers. The Federal Trade Commission claims that 46,000 people reported losing over a billion dollars in cryptocurrency to scammers in the first six months of 2021,1 a figure only including those potentially few people have been brave enough to share that they have been victims. The world of cryptocurrency can be scary for the uninitiated. One common way in which crypto-fraud is accomplished is through social media and the use of fake accounts. Some accounts purport to be crypto-fans, others make you belive they are experts in crypto-investment and are happy to help you uncover hidden riches. All of them, however, are seeking to take your money and leave you with nothing but fear and regret. This crypto-bestiary will present you, the neophyte, six of the most terrifying of crypto-creatures seeking to steal your treasure. Heed what we tell you as a lesson, be wary of where you venture and watch for the signs

Cysteinyl-tRNA Deacylation Can Be Uncoupled from Protein Synthesis

Aminoacyl-tRNA synthetases (ARSs) are critical components of protein translation, providing ribosomes with aminoacyl-tRNAs. In return, ribosomes release uncharged tRNAs as ARS substrates. Here, we show that tRNA deacylation can be uncoupled from protein synthesis in an amino acid specific manner. While tRNAs coupled to radiolabeled Met, Leu Lys, or Ser are stable in cells following translation inhibition with arsenite, radiolabeled Cys is released from tRNA at a high rate. We discuss possible translation independent functions for tRNACys
