In the cases the Dubai Foundation for Women and Children has worked on, the courts have been flexible and the mother has not served a jail term.

【翻译】在迪拜妇女和儿童基金会干预的案件中，法院采取了灵活的做法，这位母亲没有服刑。

work on：从事；参与；干预。work 为不及物动词，on 是介词。

the Dubai Foundation for Women and Children has worked on 是定语从句，cases 是先行词。

如果把the Dubai Foundation for Women and Children has worked on 认定是cases 的同位语从句，那么介词on 缺少宾语，语义也不通。本句含义是，“这位母亲没有服刑，是该基金会干预的结果”。
