KG20211 electronic resource (318 p.)Lebensweltbezogene Medienforschung: Angebote - Rezeption - SozialisationBand 103-8487-8382-7 This book deals with the role of media in the period of transition from youth to adulthood. It thus continues the (media) socialisation study with socially disadvantaged children and their families, and follows on from the previous volumes in this series. What has happened to those children, who were five years old at the beginning of the study in 2005? How do young people position themselves in the face of new social challenges and new media offerings, in terms of not only their private lives, but also and in particular their professional careers? What courses of action and blueprints and capacity for action are now available to them as young adults? Furthermore, how are their closest attachment figures? On the basis of a 7th phase of research, which was conducted in 2020, this book deals with these questions.Das Buch zielt auf die Frage nach der Rolle von Medien in der Übergangsphase von Jugend ins Erwachsenenleben. Es schließt damit an die vorherigen Bände der (Medien-)Sozialisationsstudie bei sozial benachteiligten Kindern und ihren Familien an. Was ist aus den zu Beginn der Panelstudie 2005 ca. fünf Jahre alten Kindern geworden? Wie positionieren sich die jungen Menschen angesichts neuer gesellschaftlicher Herausforderungen und neuer Medienangebote im Privatleben und vor allem auch im Beruf heute? Wie sehen nunmehr ihre Handlungsoptionen, Handlungsentwürfe und Handlungskompetenzen als junge Erwachsene aus? Und wie geht es ihren engsten Bezugspersonen? Diesen Fragen geht das Buch auf Basis einer 7. Erhebungswelle 2020 nach.15 Jahre Panelstudie zurJFDbicsscBildung, Fernsehen, Jugendliche, Medienpädagogik, Milieu, Nutzung, Sozialisationsforschung, Mediengebrauch, soziale Benachteiligung, Familienforschung, Kindheits- und Jugendforschung, junges ErwachsenenalterJFDPaus-Hasebrink Ingridauth906895Sinner PhilipauthBOOK99654034700331615 Jahre Panelstudie zur (Medien-)Sozialisation3027011UNISA11972nam 22007333 450 991100668940332120221210060240.0978168392971016839297139781683929727168392972110.1515/9781683929727(MiAaPQ)EBC30286675(Au-PeEL)EBL30286675(CKB)25609445100041(DE-B1597)653988(DE-B1597)9781683929727(BIP)086603848(FR-PaCSA)88949146(FRCYB88949146)88949146(Perlego)4268385(OCoLC)1355221945(EXLCZ)992560944510004120221210d2022 uy 0engurcnu||||||||txtrdacontentcrdamediacrrdacarrierBash for Data Scientists1st ed.Bloomfield :Mercury Learning & Information,2022.©2022.1 online resource (293 pages)9781683929734 168392973X Intro -- Bash for Data Scientists -- CONTENTS -- PREFACE -- WHAT IS THE GOAL?

The code samples and scripts use the bash shell, and typically involve small datasets so you can focus on understanding the features of grep, sed, and awk. Companion files with code are available for downloading from the publisher. FEATURES:Provides the reader with power­ful command line utilities that can be combined to create simple yet powerful shell scripts for processing datasetsContains a variety of code fragments and shell scripts for data scientists, data analysts, and those who want shell-based solutions to “clean” various types of datasetsCompanion files with codeCOMPUTERS / Programming Languages / PythonbisacshComputer Science.Data Science.Pandas.Programming.Python.UNIX.awk.data mining.grep.sed.COMPUTERS / Programming Languages / Python.005.43Campesato Oswald1594522MiAaPQMiAaPQMiAaPQBOOK9911006689403321Bash for Data Scientists4389388UNINA
