H-ItalianDiaspora Development (Call for Curators -- volunteer positions)
I have the impression that this information can clarify it further:
The Kolbo Herem went in the modern time a kind of transmutation - and is called today Pulsa deNura; Ceremony that according to the study of Zion Zohar in modern Judeism is nothing more than a renewed ritual – based on the old Kolbo Herem - invented by the Eda Haredit.
See: Zion Zohar, Pulsa De-Nura: The Innovation of Modern Magic and Ritual, Modern Judaism, 27:1 (2007) pp. 72-99.
On interactions of insanity and gender in modern Jewish fiction, see:
I.L. Peretz, "Be-agaf ha-meshuga'im" (Yid. Fun dul-hoyz), esp. the first section, "Doctor or Patient"?
The following work may also be helpful: Dafna Katsnelson-Bank, Ha-shiga'on ba-sifrut ha-'ivrit be-reshit ha-me'ah he-esrim (2005)
Another lead to follow would be the theme of the dybbuk in modern Hebrew and Yiddish fiction.
