Table schema:
CREATE TABLE management (department_id VARCHAR, temporary_acting VARCHAR); CREATE TABLE department (name VARCHAR, num_employees VARCHAR, department_id VARCHAR)

Question: Show the name and number of employees for the departments managed by heads whose temporary acting value is 'Yes'?
SQL: SELECT T1.name, T1.num_employees FROM department AS T1 JOIN management AS T2 ON T1.department_id = T2.department_id WHERE T2.temporary_acting = 'Yes'
