To the surmise that my timeline ought to contain a particular proportion of tweets from physicists in other subdisciplines. This maybe naive expectation runs counter to my knowledge. Furthermore,in a (Twittermediated) conversation,the question was posed no matter whether,in the course of academic conferences,Twitter registered similar levels of use by physicists operating in unique subdisciplines. The stimulus for the question was the observation of low Twitter activity at an international Dan shen suan A conference onStephen Webb stephen.x.webbport.ac.ukDCQE,University of Portsmouth,St Michael’s Road,Portsmouth PO PR,UKScientometrics :magnetism: anecdotal evidence suggested that members of the astronomy neighborhood,one example is,have been extra active users of Twitter than members with the condensed matter neighborhood. A literature overview failed to uncover study into this query. For that reason,in an try to identify irrespective of whether you will discover subdisciplinary differences in Twitter use,I undertook a study of scientific conferences whose theme was associated with some region of physics or astronomy. Seven conferences were subsequently deemed unsuitable for evaluation. An evaluation of tweets from the remaining conferences is constant together with the suggestion that different physics subdisciplines do indeed use Twitter in differing degrees. This paper is organized as follows. For readers that are unfamiliar with what exactly is nevertheless a comparatively new tool for scholarly communication,the “Background PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/24023058 and nomenclature” section presents some brief background to Twitter and explains the relevant nomenclature. The “Methods” section describes the strategies employed plus the “Results” section presents the outcomes of an evaluation on the information. Following the “Conclusion” section,in which doable motives for the observed distinction in Twitter use are explored,an “Appendix” lists the names from the conferences used within the analysis; this,combined using the open nature of Twitter,permits replication from the work.Background and nomenclatureThe Twitter platformTwitter is an on the net microblogging platform that allows its users (“tweeps”) to publish messages of characters or less. These messages (“tweets”) may also involve URLs,photos or videos. 1 user can choose to “follow” another; when somebody publishes a tweet that message quickly seems within the timeline of all those who follow that person. The character limit essentially guarantees the absence of nuance in tweets,and there is a possibility that complicated concepts might be decreased and misrepresented as “sound bites”. Nonetheless,Twitter’s mixture of brevity and immediacy has made it a well-liked platform: as of June there were million active users monthly,with million tweets getting published daily (about.twitter. Regardless of the message length restriction,tweeps use the service to publish opinions,gossip and news. In addition to its widespread application in politics and journalism,largescale research of Twitter use have been employed by scientists for a assortment of ends,such as the augmentation of earthquake response systems (Earle et althe investigation of how health info is disseminated (Scanfield et al. and as a suggests of estimating crowd size (Botta et al A variety of attributes improve Twitter’s use as a communication tool as well as facilitate subsequent analysis of tweets. 1st,Twitter has a “retweet” function. If a person retweets a tweet,the original tweet appears within the timelines of that tweep’s followers and is identified as a retweet (RT). Holmberg and Thelwa.
