Perhaps you should try some spelling variations:
"hedonic model" » "hedonica model", "hedonico model"
"hedonismo model" » "peronismo model", "helenismo model", "hedonico model"
"hedonista model" » "peronista model", "hedonica model", "helenista model"
"hedonista modelo" » "peronista modelo", "hedonica modelo", "helenista modelo", "hedonista modelos"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"hedonic model\") OR (((\"hedonismo model\") OR (((\"hedonista model\") OR (\"hedonista modelo\"))))))~".
• Removing quotes may allow a broader search: (( hedonic model ) OR ((( hedonismo model ) OR ((( hedonista model ) OR ( hedonista modelo ))))))~.
• Adding a wildcard symbol may retrieve word variants: (("hedonic model") OR ((("hedonismo model") OR ((("hedonista model") OR ("hedonista modelo"))))))*.
