    The Pennsylvania State University The Graduate School College of Communications EVALUATIO OF FOSS VIDEO GAMES I COMPARISO TO THEIR COMMERCIAL COUTERPARTS A Thesis in Media Studies By Jesse A. Clark © 2008 Jesse A. Clark Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Arts August 2008 ii The thesis of Jesse A. Clark was reviewed and approved* by the following:: John Nichols Professor of Communications Associate Dean for Graduate Studies and Research Matt Jackson Associate Professor of Communications Head of Department of Telecommunications Thesis Advisor Robert Frieden Professor; Pioneers Chair in Telecommunications Ronald Bettig Associate Professor of Communications *Signatures are on file in the Graduate School. iii Abstract The topic of copyrights and copyright law is a crucial component in understanding today's media landscape. The purpose for having a copyright system as outlined in the U.S. Constitution is to provide content creators with an incentive to create. The copyright system allows revenue to be generated through sales of copies of works; thus allowing for works to be created which otherwise would not be created. Yet it is entirely possible that not all large creative projects require the same legal framework as an incentive. The so called “copyleft” movement (which will be defined and explained in depth later) offers an alternative to the industrial mode of cultural production. Superficially, “copylefted” works can be divided into two broad categories: artistic/creative works (which are often protected by “Creative Commons” licenses), and Free/Open Source Software. This thesis evaluates how open source video games compare to their commercial counterparts and discusses the reasons for any difference in overall quality.

Entre os anos de 2010 a 2012, os índices de acidentes ocasionados por motoristas foi muito superior a outras causas como rodovias e veículos em más condições. No ano de 2012, por exemplo, 90,15% dos acidentes ocorridos foram por comportamento inadequado do motorista, em um total de 12868 acidentes ocorridos no Rio Grande do Sul. A Figura 1 exibe a quantidade de acidentes de 2010 a 2012 de acordo com a causa (MASIERO).
