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)
"publicaaas administration" » "publicaaaas administration" (Expandir a Busca), "publicoaaas administration" (Expandir a Busca), "publicasaaas administration" (Expandir a Busca), "publicaaas administracao" (Expandir a Busca), "publicas administration" (Expandir a Busca), "publicass administration" (Expandir a Busca)
"publicaaa administration" » "publicaaaa administration" (Expandir a Busca), "publicoaaa administration" (Expandir a Busca), "publicasaaa administration" (Expandir a Busca), "publicaaa administracao" (Expandir a Busca), "publica administration" (Expandir a Busca), "publicas 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 (\"publicaaas administration\"))) OR (\"publicaaa administration\"))~".
• Remover as aspas pode possibilitar buscas mais amplas: (((( public administration ) OR ( publicaaas administration ))) OR ( publicaaa administration ))~.
• Adicionar um caractere curinga pode recuperar variações da palavra buscada: (((("public administration") OR ("publicaaas administration"))) OR ("publicaaa administration"))*.
