The meaning of social media for women domestic workers during the Covid-19 pandemic
No full textSocial media plays an important role during the Covid-19 pandemic, where physical activity and community mobility are limited. Especially for women who work as domestic workers who live with their employers. Social media is the only means for them to connect with the outside world.Previous studies have shown that a person\u27s identity can be shown through the front stage and the back stage. Theoretically, this study analyzing how women domestic workers identify themselves through the online realm using social media. This study uses a constructivist paradigm and a qualitative approach. The research participants were three women domestic worker who were obtained purposively using the snowball sampling technique. Data was collected through in-depth interviews and observation to participants. The results of the study show that social media allows participants to construct a reality in the online realm that is different from their situation in real life. Therefore, social media has a very important meaning for participants, because with social media, participants feel their position is equal to other users. They also have access to create a front stage and a back stage, where they can create their ideal self-identity. The aspect of self that are presented by the participants on the front stage is individuals who are successful and happy with their lives. For participants, this is an aspect of their ideal self, even though it does not represent their actual state
Islamic vigilantism and women in social media
No full textIn Bangladesh, the number of cyber-citizens has been skyrocketing since the 2010s. Violence against women is also proliferating along with the presence of Islam in public spheres and discourses. Using thematic analysis, this study analyzes the discourse data collected from Facebook, the dominant social media of Bangladesh. The key aim of the research is to find out the bedrock of Islamic vigilantism and verbal aggressiveness against women in social media. Subsequently, three interlinked themes have been explored: women\u27s religiosity, women\u27s attire, and women\u27s virtue. The findings have shown that men mainly capitalize on these three conventional and stereotyped ideas of popular Islam to conduct vigilantism against women in social media, which is most often accompanied by different types of verbal aggressiveness. Further, this study considering deep-rooted misogyny and patriarchy in Bangladesh society argues that these factors might have contributed to directing online vigilantism against women. As little research has been done in this area, this research study would lead to further researches in this area
