Any largescale studies have examined scientists’ motivation for reside tweeting at conferences. However,basically from reading conference tweets,a single can posit quite a few reasons. There’s generally a clearly scientific aspect to a tweet: a user could possibly hyperlink to a preprint,for instance. There may be an outreach aspect to a tweet: an individual can use NSC618905 Twitter to reach networks outside of academe. A conference participant could possibly tweet in order to offer data,and a flavour of the event,to colleagues who cannot attend. An increasingly well-liked activity at scientific and technical conferences is a style of visual notetaking called sketchnoting; some participants choose to share their notes working with a #sketchnote hashtag. A tweet could be a indicates of raising points of contention; for example,the hashtag #everydaysexism has been employed to flag conference speakers’ language or attitudes. A tweet can have a purely social aspect. Twitter can be employed for networking: employers can tweet the availability of jobs and postgraduates can enquire about possibleScientometrics :postdoctoral positions. Twitter might be utilized by conference organisers as a channel for news,and delegates can use the service to ask for information. The platform can be utilised by sponsors and exhibitors to promote their presence,and by regional authorities to extol the virtues in the location surrounding the conference venue. A qualitative study would surely identify yet a lot more factors why live tweeting takes location at scientific conferences. The etiquette surrounding the use of Twitter at scientific conferences continues to be evolving. As an example,in the annual meeting of your Ecological Society of America held in August ,the conference organisers’ request for attendees to achieve consent from speakers ahead of tweeting about presentations caused confusion (Woolston. There remains debate about whether or not conference policy really should default to let reside tweeting unless a speaker explicitly asks attendees not to do so. On the other hand,a lot of conference organisers explicitly encourage delegates to tweet applying a specific hashtag.Harvesting tweets for analysisSearching historical Twitter information is possible,but may be expensive if a single wishes to carry out something apart from simple analytics. Nevertheless,Twitter makes publicly accessible APIs that let 1 to access its network stream in two different techniques. The very first strategy enables a user,in true time,to harvest tweets that meet offered conditions; hence a tweet containing a specific hashtag could be piped to a file for later evaluation. The second strategy permits a user to search for and retailer all tweets posted within a preceding day period that meet offered circumstances. These APIs gave sufficient access to the service for the purposes described within this paper.MethodsIdentification and classification of conferencesDuring PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/28497198 summer ,a register of forthcoming academic conferences relating to subject places in physics,astronomy and cognate disciplines was prepared from public listings onTable Toplevel headings of PACS Classification Branch of physics or astronomy Common The physics of elementary particles and fields Nuclear physics Atomic and molecular physics Electromagnetism,optics,acoustics,heat transfer,classical mechanics,and fluid dynamics Physics of gases,plasmas,and electric discharges Condensed matter: structural,mechanical,and thermal properties Condensed matter: electronic structure,electrical,magnetic,and optical properties Interdisciplinary physics and related locations of science and technolog.
