[{"$nulls":4},"The digital revolution is interwoven with the promise to empower the user. Yet, the rise of centralised, commercial platforms for crowdsourced work questions the validity of this narrative. In Crowd-Design, Florian Alexander Schmidt analyses the workings and the rhetoric of crowdsourced work platforms by comparing the way they address the masses today with historic notions of the crowd. The utopian concepts of early online collaboration are taken as a vantage point from which to view and critique current and, at times, dystopian applications of crowdsourced work. The study is focused on the crowdsourcing of design tasks, but these specific applications are used to examine the design of the more general mechanisms employed by the platform providers to motivate and control the crowds. Crowd-Design is as much about the crowdsourcing of design as it is about the design of crowdsourcing."]

[null,null,null,"Sommario/riassunto","Considerable recent research has focused on the topic of chemical speciation in the environment. It is increasingly realised that the distribution, mobility and biological availability of chemical elements depend not simply on their concentrations but, critically, on the forms in which they occur in natural systems. Continuing developments in analytical chemistry have made speciation practicable even where analytes are present at trace levels (as is often the case in natural samples).  In the second edition of this book, the expertise of scientists involved in chemical speciation in various fields have been brought together to provide an overview of the current status of speciation science and indicate how the field may develop in the future"]
