Applications accepted all year round

Applications are invited for a self-funded 3-year PhD.

The PhD will be based in the Faculty of Business and Law, and will be supervised by Dr Diletta Acuti and Prof Giampaolo Viglia

The work on this project could involve:

  • A systematic literature review to identify the factors that facilitate the engagement of individuals in the dialogue about CSR activities on social media.
  • A mixed-method approach – including qualitative and quantitative methods – to understand the role of message construal and individual characteristics in fostering consumer engagement in CSR dialogue.
  • The identification of recommendations for practical communication approaches that can leverage message characteristics to enable effective CRS communication.
  • A potential interdisciplinary collaboration with different departments of the University of Portsmouth and the Centre for Blue Governance, which address CSR both generally and specifically on plastic. 

This PhD project aims to explore how companies can engage individuals in the dialogue about CSR (corporate social responsibility) on social media. Specifically, by adopting a Construal Level Theory perspective (Trope et al., 2007), the project wants to analyse the “plastic in the oceans” phenomenon in order to identify the factors that lead consumers to engage in CSR contents on social media and open dialogues about environmental issues (Glozer et al., 2019).

Recently people started becoming more and more aware of the impact of plastic on marine life as environmental consequence of companies’ activities. As a result of this growing awareness, several activists, companies and even governments have started addressing this topic with the aim of finding substitutes as well as new recycling solutions for the material.

Statistics on social media show how people are becoming more interested in plastic waste dialogue: tweets about plastic waste are growing as well as users are increasingly googling about plastic waste (Brandwatch, 2018). A hypothesis on the success of “plastic in the oceans” dialogue spread can rely on the perceived tangibility of the (negative) impact of plastic and on the self- efficacy people can feel in addressing this issue. Environmental responsibility communication construals can therefore have important implications on consumers’ engagement in dialogue about CSR (Line et al., 2016).

The project has three main aims. Firstly, to identify the message characteristics such as the degree of vividness and the construals that can foster consumer’ engagement in CSR communication through social media. Secondly, to explore the role played by individual factors in influencing such engagement’s process. Finally, the project seeks to provide companies with a deeper understanding on how to communicate their CSR initiatives to their consumers in a more effective way.
