    Harvesting Wisdom on Social Media for Business Decision Making
    (HICSS, 2022-01-01) Yu J; Taskin N; Pauleen DJ; Jafarzadeh H; Bui TX
    The proliferation of social media provides significant opportunities for organizations to obtain wisdom of the crowds (WOC)-type data for decision making. However, critical challenges associated with collecting such data exist. For example, the openness of social media tends to increase the possibility of social influence, which may diminish group diversity, one of the conditions of WOC. In this research-in-progress paper, a new social media data analytics framework is proposed. It is equipped with well-designed mechanisms (e.g., using different discussion processes to overcome social influence issues and boost social learning) to generate data and employs state-of-the-art big data technologies, e.g., Amazon EMR, for data processing and storage. Design science research methodology is used to develop the framework. This paper contributes to the WOC and social media adoption literature by providing a practical approach for organizations to effectively generate WOC-type data from social media to support their decision making.

    Keeping the gates closed: the effect of conflict management styles, anxiety, and technical skills on security noncompliance intention among smartphone users
    (Taylor and Francis Group, 2024-08-12) Rahmani D; Jafarzadeh H; Hess AC
    Using personal mobile phones for work-related purposes is an increasingly common trend in organisations yet adding to cyber security concerns. It is vital to identify employees’ characteristics that impact security noncompliance behaviours when using mobile phones at work, as it could open a channel for cyber-attacks in the enterprise's IT systems. Using the unique context of personal smartphones and building on the theoretical framework of the Dual-Concern Model, this study identifies key characteristics of employees’ intention to engage in security noncompliance activities. Through a scenario-based survey of 391 mobile phone users in the United States, we examined the impact of personal characteristics (specifically conflict management style, context-specific anxiety, and technological skills) in explaining people’s intention to demonstrate security noncompliance behaviours. Younger individuals, those with higher conflict approach tendencies, and those with online communication apprehension tend to show higher noncompliance with information system security policies. Also, technical skills were found to moderate the association of online communication apprehension with increased noncompliance with security policies. The findings offer a range of theoretical implications and practical insights for strengthening organisations’ cyber security.

    Making sense of COVID-19 over time in New Zealand: Assessing the public conversation using Twitter
    (PLOS, 2021-12-15) Jafarzadeh H; Pauleen DJ; Abedin E; Weerasinghe K; Taskin N; Coskun M; Mehmood R
    COVID-19 has ruptured routines and caused breakdowns in what had been conventional practice and custom: everything from going to work and school and shopping in the supermarket to socializing with friends and taking holidays. Nonetheless, COVID-19 does provide an opportunity to study how people make sense of radically changing circumstances over time. In this paper we demonstrate how Twitter affords this opportunity by providing data in real time, and over time. In the present research, we collect a large pool of COVID-19 related tweets posted by New Zealanders-citizens of a country successful in containing the coronavirus-from the moment COVID-19 became evident to the world in the last days of 2019 until 19 August 2020. We undertake topic modeling on the tweets to foster understanding and sensemaking of the COVID-19 tweet landscape in New Zealand and its temporal development and evolution over time. This information can be valuable for those interested in how people react to emergent events, including researchers, governments, and policy makers.
