Finally the question arises: if the patriarchal structures are not questioned, is the prison an effective place to confront and deal with sexist violence? 1 Trabajo 1 Trabajo doméstico remunerado 1 Trans women 1 University extension 1 Violencia de género 1 Women 1 Women deprived of liberty 1 Work 1 asistencia social 1 campo de saberes 1 depreciation 1 desvalorización 1 fi eld of knowledge 1
