Moroccan nationality law: Moroccan nationality law is the subject of the Moroccan Dahir (decree) of September 6, 1958, official Bulletin Number 2394.  In general, Moroccan nationality is transmitted by filiation (father and mother) or birth in Morocco.  However, it gives the right to Moroccan males to transmit citizenship to their children and foreign wives, and since the last update, that is possible for women.  The aim of the update was to follow Morocco's recent human rights reforms, most notably the Moroccan family code called, "Mudawana", which aimed to fight gender inequality.  It has been done after much debate in the media.

The Italian (novel): The Italian, or the Confessional of the Black Penitents (1797) is a Gothic novel written by the English author Ann Radcliffe.  It is the last book Radcliffe published during her lifetime (she would go on to write the novel "Gaston de Blondeville", which was published posthumously in 1826).  "The Italian" has a dark, mysterious and somber tone, and concerns the themes of love, devotion and persecution by the Holy Inquisition.  The novel also deals with issues prevalent at the time of the French Revolution, such as religion, aristocracy, and nationality.  Radcliffe's renowned use of veiled imagery is considered to have reached its height of sophistication and complexity in "The Italian"; concealment and disguise are central motifs of the novel.  In line with late 18th-century sensibility and its parallel fetishisation of the sublime and the sentimentally pastoral, the heightened emotional states of Radcliffe's characters are often reflected through the pathetic fallacy.  The novel is noted for its extremely effective antagonist, Father Schedoni.
