Talvez deva tentar algumas variações de ortografia:
"public administration" » "publica administration" (Expandir a Busca), "publico administration" (Expandir a Busca), "publicas administration" (Expandir a Busca), "public administracao" (Expandir a Busca)
"publicoos administration" » "publicaoos administration" (Expandir a Busca), "publicooos administration" (Expandir a Busca), "publicasoos administration" (Expandir a Busca), "publicoos administracao" (Expandir a Busca), "publicos administration" (Expandir a Busca), "publico administration" (Expandir a Busca), "publicas administration" (Expandir a Busca)
"publicoasa administration" » "publicaoasa administration" (Expandir a Busca), "publicooasa administration" (Expandir a Busca), "publicasoasa administration" (Expandir a Busca), "publicoasa administracao" (Expandir a Busca), "publicas administration" (Expandir a Busca), "publicos administration" (Expandir a Busca)

Você pode obter mais resultados ajustando o argumento de busca.

• As palavras AND, OR e NOT pode ocasionar problemas na busca; tente utilizar as aspas: "((((\"public administration\") OR (\"publicoos administration\"))) OR (\"publicoasa administration\"))~".
• Remover as aspas pode possibilitar buscas mais amplas: (((( public administration ) OR ( publicoos administration ))) OR ( publicoasa administration ))~.
• Adicionar um caractere curinga pode recuperar variações da palavra buscada: (((("public administration") OR ("publicoos administration"))) OR ("publicoasa administration"))*.
