In Group Cognition Gerry Stahl explores the technological and social reconfigurations that are needed to achieve computer-supported collaborative knowledge building--group cognition that transcends the limits of individual cognition. Computers can provide active media for social group cognition where ideas grow through the interactions within groups of people; software functionality can manage group discourse that results in shared understandings, new meanings, and collaborative learning. Stahl offers software design prototypes, analyzes empirical instances of collaboration, and elaborates a theory of collaboration that takes the group, rather than the individual, as the unit of analysis.Stahl's design studies concentrate on mechanisms to support group formation, multiple interpretive perspectives, and the negotiation of group knowledge in applications as varied as collaborative curriculum development by teachers, writing summaries by students, and designing space voyages by NASA engineers. His empirical analysis shows how, in small-group collaborations, the group constructs intersubjective knowledge that emerges from and appears in the discourse itself. This discovery of group meaning becomes the springboard for Stahl's outline of a social theory of collaborative knowing. Stahl also discusses such related issues as the distinction between meaning making at the group level and interpretation at the individual level, appropriate research methodology, philosophical directions for group cognition theory, and suggestions for further empirical work. 410 0$aActing with technology 606 $aComputer networks 606 $aComputer-assisted instruction 608 $aElectronic books. 615 0$aComputer networks. 615 0$aComputer-assisted instruction. 676 $a371.33/4 686 $a54.61$2bcl 686 $a81.68$2bcl 700 $aStahl$b Gerry$0849821 801 0$bCaBNVSL 801 1$bCaBNVSL 801 2$bCaBNVSL 906 $aBOOK 912 $a9910451918603321 996 $aGroup cognition$92027117 997 $aUNINA LEADER 03559nam 22007572 450 001 9910458247703321 005 20151005020622.0 010 $a1-107-17457-0 010 $a1-281-37060-6 010 $a9786611370602 010 $a0-511-39422-5 010 $a0-511-39214-1 010 $a0-511-39487-X 010 $a0-511-39091-2 010 $a0-511-53540-6 010 $a0-511-39345-8 035 $a(CKB)1000000000399179 035 $a(EBL)336072 035 $a(OCoLC)437204634 035 $a(SSID)ssj0000140060 035 $a(PQKBManifestationID)11911766 035 $a(PQKBTitleCode)TC0000140060 035 $a(PQKBWorkID)10028960 035 $a(PQKB)11068791 035 $a(UkCbUP)CR9780511535406 035 $a(MiAaPQ)EBC336072 035 $a(Au-PeEL)EBL336072 035 $a(CaPaEBR)ebr10224580 035 $a(CaONFJC)MIL137060 035 $a(EXLCZ)991000000000399179 100 $a20090429d2008|||| uy| 0 101 0 $aeng 135 $aur||||||||||| 181 $ctxt$2rdacontent 182 $cc$2rdamedia 183 $acr$2rdacarrier 200 10$aDissociative recombination of molecular ions /$fMats Larsson and Ann E.

Its critical role as a neutralising agent in the Earth's upper atmosphere is now well established and its occurrence in many natural and laboratory-produced plasma has been a strong motivation for studying the event. In this book theoretical concepts, experimental methodology and applications are united, revealing the governing principles behind the gas-phase reaction. The book takes the reader through the intellectual challenges posed, describing in detail dissociation mechanisms, dynamics, diatomic and polyatomic ions and related processes, including dissociative excitation, ion pair formation and photodissociation. With the final chapter dedicated to applications in astrophysics, atmospheric science, plasma physics and fusion research, this is a focused, definitive guide to a fundamental molecular process. The book will appeal to academics within physics, physical chemistry and related sciences. 410 0$aCambridge molecular science series. 606 $aIon recombination 606 $aDissociation 606 $aIons 606 $aElectrons 606 $aMolecular structure 615 0$aIon recombination. 615 0$aDissociation. 615 0$aIons. 615 0$aElectrons. 615 0$aMolecular structure. 676 $a539/.6 700 $aLarsson$b Mats$c(Physics teacher),$0117489 702 $aOrel$b Ann E. 801 0$bUkCbUP 801 1$bUkCbUP 906 $aBOOK 912 $a9910458247703321 996 $aDissociative recombination of molecular ions$92466840 997 $aUNINA
