-This page contains the most relevant verb preposition (VPC) and adjective preposition combinations (APC) for English learners with different L1's from our publication //Crossing the Border Twice: Reimporting Prepositions to Alleviate L1-Specific Transfer Errors//.  The lists have been filtered such that the raw frequency $f_V$ is required to be at least 100 and //by// is not allowed as preposition $\lambda_p$ due to the frequent use of passive verb forms in [[public:costep:start|source material]].  The same lists with a filter of $f_V \ge 5$ are available [[https://pub.cl.uzh.ch/users/graen/vpc_apc_export/|here]].+This page contains the most relevant verb preposition (VPC) and adjective preposition combinations (APC) for English learners with different L1's from our publication [[http://www.zora.uzh.ch/137099/|Crossing the Border Twice: Reimporting Prepositions to Alleviate L1-Specific Transfer Errors]].  The lists have been filtered such that the raw frequency $f_V$ is required to be at least 100 and //by// is not allowed as preposition $\lambda_p$ due to the frequent use of passive verb forms in [[public:costep:start|source material]].  The same lists with a filter of $f_V \ge 5$ are available [[https://pub.cl.uzh.ch/users/graen/vpc_apc_export/|here]].
