A Deviant Or A Victim Of Pervasive Stigmatization: Wicked Women In Kavita Kané’S Lanka’S Princess, Meenakshi Meenakshi, Nagendra Kumar

Journal of International Women's Studies

Building on the foundational theories of Judith Butler and Edwin Schur, this paper scrutinises the traditional myth of the Hindu epic the Ramayana and argues: (1) how socially constructed gender performance is naturalised by cultural ideology and (2) how infringement of this performance leads to labelling individuals as deviant. Women who transgress these cultural ideologies are defined as deviant and subjected to various punishments, from public humiliation to genital mutilation. Through an exploration of the novelist Kavita Kané’s mythology inspired novel Lanka’s Princess (2017), this paper focuses on the mythical figure known as Surpankha whose character embodies masculine attributes …

Warrior Mothers: Narratives Of Women From The United Liberation Front Of Assam (Ulfa), Munmi Pathak

Journal of International Women's Studies

The archetype of the mother is always perceived as ‘pacifist’ in war and conflict situations. However, there are numerous examples when mothers are not ‘pacifist’ but become participants and perpetrators of war. This article, through the analysis of the experiences of the mothers in the United Liberation Front of Assam (ULFA), an armed nationalist organization waging war against the Indian nation-state to establish ‘sovereignty’ and ‘liberate’ Assam since1979, argues that mothers can also be warriors, going beyond their ‘pacifist’ archetype. With the analysis of the oral narratives of the women cadres of the organization, this article discusses how these mothers …

A Good Wife Or A Greedy Wife? Women's Roles As Wives In Chinese Corruption News Coverage, Yiyan Li

Journal of International Women's Studies

Xi Jinping, China’s president, has embarked on the largest anti-corruption campaign in modern Chinese history. This study provides insight into the media representing the wife figure in contemporary corruption news in China. To this end, this study employs critical discourse analysis to analyse news articles from the Central Committee for Discipline Inspection (CCDI). The data reveals news articles depict wives of corrupt cadres as greedy if they have participated in their husbands’ corrupt behaviors. In this sense, wives are represented as being responsible for their husbands’ corruption, while the ruling party’s role is marginalized. Thus, this representational strategy allows the …

Patriarchal Limitations Imposed On African Women: A Deconstructive Reading Of Chinweizu’S Anatomy Of Female Power, Itang Ede Egbung

Journal of International Women's Studies

Patriarchy is one of the crippling limitations that women face in contemporary societies despite the effects of modernism. Patriarchy is a system that thrives on the domination of women and promotes the superiority of men. The system places so many limitations on women to the extent that the subversion of these limitations is considered a violation of social norms and values. This paper discovers that patriarchal limitations have confined unassertive women to be at the whims and caprices of men and their domination. Using deconstructive critical theory, this paper deconstructs Chinweizu’s Anatomy of Female Power which claims that women wield …

Men And Women Revisiting Women’S Conventional Roles In Selected Contemporary African Novels, Akinola Monday Allagbe, Yacoubou Alou

Journal of International Women's Studies

Many theorists, feminist scholars, and critics have been divided on the question of if it is possible for both men and women to adequately write about women. This article examines how some contemporary men and women have redefined and represented African women in their fiction, discharging them of conventional roles in patriarchal settings. To prove this, we examine instances of reversal of women’s conventional roles through womanist and radical feminist trends in four selected contemporary African novels written by both men and women: Mema (2003), A Beautiful Daughter (2012), The Housemaid (1998), and The Secret Lives of Baba …
