But what are the wider effects of whistleblowing as an act of dissent on politics, society, and the arts? How does it contribute to new courses of action, digital tools, and contents? This urgent intervention based on the work of Berlin's Disruption Network Lab examines this growing phenomenon, offering interdisciplinary pathways to empower the public by investigating whistleblowing as a developing political practice that has the ability to provoke change from within. 410 $aDigitale Gesellschaft 606 $aWhistleblowing; Social Justice; Resistance; Hacktivism; Digital Culture; Civil Society; Politics; Media; Political Sociology; Digital Media; Media Studies; Political Science; 610 $aCivil Society. 610 $aDigital Culture. 610 $aDigital Media. 610 $aHacktivism. 610 $aMedia Studies. 610 $aMedia. 610 $aPolitical Science. 610 $aPolitical Sociology. 610 $aPolitics. 610 $aResistance. 610 $aSocial Justice. 615 4$aWhistleblowing; Social Justice; Resistance; Hacktivism; Digital Culture; Civil Society; Politics; Media; Political Sociology; Digital Media; Media Studies; Political Science; 702 $aBazzichelli$b Tatiana$pDisruption Network Lab e.V., Deutschland$4edt 801 0$bScCtBLL 801 1$bScCtBLL 906 $aBOOK 912 $a996453549803316 996 $aWhistleblowing for Change$92564251 997 $aUNISA LEADER 05192nam 2200625Ia 450 001 9910830126803321 005 20170816123216.0 010 $a1-280-52083-3 010 $a9786610520831 010 $a3-527-60599-1 010 $a3-527-60595-9 035 $a(CKB)1000000000377380 035 $a(EBL)482251 035 $a(OCoLC)69157440 035 $a(SSID)ssj0000158396 035 $a(PQKBManifestationID)11155961 035 $a(PQKBTitleCode)TC0000158396 035 $a(PQKBWorkID)10144906 035 $a(PQKB)10034391 035 $a(MiAaPQ)EBC482251 035 $a(PPN)167456334 035 $a(EXLCZ)991000000000377380 100 $a20041112d2004 uy 0 101 0 $aeng 135 $aur|n|---||||| 181 $ctxt 182 $cc 183 $acr 200 10$aFrequency standards$b[electronic resource] $ebasics and applications /$fFritz Riehle 210 $aWeinheim $cWiley-VCH$dc2004 215 $a1 online resource (542 p.) 300 $aDescription based upon print version of record. 311 $a3-527-40230-6 320 $aIncludes bibliographical references (p.

It equally allows precise measurements of other physical and technical quantities, whenever they can be measured in terms of frequency.This volume covers the central methods and techniques relevant for frequency standards developed in physics, electronics, quantum electronics, and statistics. After a review of the basic principles, the book looks at the realisation of commonly used components. It then continues with the description and characterisation of important frequency standards 606 $aFrequency standards 606 $aStandards, Engineering 615 0$aFrequency standards. 615 0$aStandards, Engineering. 676 $a529.750971 676 $a621.3815363 700 $aRiehle$b Fritz$01637526 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910830126803321 996 $aFrequency standards$93979396 997 $aUNINA
