This treatise provides useful insights and understanding of the chiral/achiral designations (nomenclatures), the stereochemical features, and related properties of the natural and synthetic products. Without having an adequate knowledge of stereochemical concepts, it will not be possible to understand and appreciate the stereochemistry of natural or synthetic products. Thus, essential static and dynamic aspects of stereochemistry with sufficient illustrative examples along with discussions are presented. The structure of the monograph allows for easy selection of separate topics for reading and teaching. This book will also provide an idea of basic stereochemical concepts, as applied to organic molecules in general as well as to organic ligands in coordination complexes, and will, therefore, be valuable resources to teachers and students of advanced undergraduates and post-graduates, researchers, and professionals. 606 $aStereochemistry 615 0$aStereochemistry. 676 $a547.1223 700 $aTalapatra$b Sunil Kumar$0922394 702 $aTalapatra$b Bani 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910637715803321 996 $aBasic concepts in organic stereochemistry$93364517 997 $aUNINA LEADER 02731nam 2200493z- 450 001 9910831840703321 005 20230221133630.0 035 $a(CKB)5470000000566244 035 $a(oapen)https://directory.doabooks.org/handle/20.500.12854/26861 035 $a(oapen)doab26861 035 $a(EXLCZ)995470000000566244 100 $a20||||||d2019 |y e 101 0 $aeng 135 $aurmn|---annan 181 $ctxt$2rdacontent 182 $cc$2rdamedia 183 $acr$2rdacarrier 200 00$aChapter 4 The social value of anonymity on campus$ea study of the decline of Yik Yak 210 $cTaylor & Francis$d2019 215 $a1 online resource (16 p.) 311 08$a0-429-34135-0 330 $a"This paper considers the social value of anonymity in online university student communities, through the presentation of research which tracked the final year of life of the social media application Yik Yak. Yik Yak was an anonymous, geosocial mobile application launched in 2013 which, at its peak in 2014, was used by around two million students in the US and UK. The research we report here is significant as a mixed method study tracing the final year of the life of this app in a large UK university between 2016 and 2017. The paper uses computational and ethnographic methods to understand what might be at stake in the loss of anonymity within university student communities in a datafied society. Countering the most common argument made against online anonymity - its association with hate speech and victimisation - the paper draws on recent conceptual work on the social value of anonymity to argue that anonymity online in this context had significant value for the communities that use it. This study of a now-lost social network constitutes a valuable portrait by which we might better understand our current predicament in relation to anonymity, its perceived value and its growing impossibility." 517 $aChapter 4 The social value of anonymity on campus 606 $aEducation$2bicssc 610 $aAnonymity 610 $acampus 610 $acommunity 610 $adatafication 610 $aephemerality 610 $asocial media 610 $athema EDItEUR::J Society and Social Sciences::JN Education 610 $aYik Yak 615 7$aEducation 700 $aBayne$b Sian$4auth$01842269 702 $aConnelly$b Louise$4auth 702 $aGroverc$b Claire$4auth 702 $aOsborned$b Nicola$4auth 702 $aTobinc$b Richard$4auth 702 $aBeswicke$b Emily$4auth 702 $aRouhanif$b Lilinaz$4auth 906 $aBOOK 912 $a9910831840703321 996 $aChapter 4 The social value of anonymity on campus$94422297 997 $aUNINA
