Alternative Food Networks (AFNs) are a system of food provision which is considered as the embodiment of the Sustainable Development (SD) agenda. They typically operate counteractively to conventional food networks (CFNs) seeking to reconnect all members in the supply chain through ethical and sustainable engagements. They are grounded by the theoretical underpinnings of quality conventions (Murdoch, 2000; Thévenot, 2002) and embeddedness notions such as alterity, valorisation, and appropriation (Dansero & Puttilli, 2014; Kirwan, 2004). Many scholars have focused on exploring AFNs in various contexts, initially focusing on binary notions of dichotomy between AFNs and CFNs, then developing discourse in terms of assessing hybridity (Holloway et al., 2006; Maye, 2013; Ponte, 2016; Renting, Marsden, & Banks, 2003; Tregear, 2011). Recent studies have indicated the potential for further research concerning social media based AFNs (Bos & Owen, 2016; Reed & Keech, 2017; Wills & Arundel, 2017). Therefore a contribution in terms of further understanding this issue arises from this thesis. The research was conducted in the midst of the referendum for the UK to withdraw from the European Union, the subsequent ‘leave’ vote resulting in a level of uncertainty in terms of policy implications. One policy implication may be that the UK will have to readdress the way it engages and supports its food and agriculture sector post-Common Agricultural Policy, therefore this research comes at a timely juncture. This research adopts an interpretivistic epistemological stance, with a constructivist ontological position. Social network analysis (SNA) of Twitter connections was conducted in order to assess connectivity and density of the AFN that was present in Chester and its region. Content analysis of this network was then conducted in order to understand SD related terms and shortlist pertinent actors for further analysis. Interviews were conducted with nine actors from this network in order to critically evaluate their perceptions of SD from an online and offline perspective. The results of the SNA suggest that the AFN of Chester and its region was not particularly well connected in terms of density. However, the SNA was a useful data collection tool, especially concerning the replicability and transferability of participant selection strategy. Further results suggested that there was a need for more organisational structures to support AFNs in becoming more mainstream and collaborative. It was also clear that there was still a degree of opposition between CFNs and AFNs, despite hybridity. A final finding of the research is the consideration of smart localism. The implications of this research are discussed, along with suggestions for future research including; the need to better understand leadership, relations between AFNs and CFNs, the role played by intermediates, and the expansion of social media based research.

Conceptualizing the locality today in the global context means to be able to consider a level of denationalisation of the actor (of a locality) participating in a networked situation with actors from other localities. This thesis introduces a new conceptualization of the locality participating in a transnational network. The network, CEARENAD, involved six localities (Brazil, Chili, Costa-Rica, Senegal, Mauritius and Canada) who co-constructed contents for five years. This research is about presenting not a "mode d'emploi" about whether this particular network was successful or not. What truly motivated me, during and about this research, was to reflect on my observations of this network to build a new conceptualisation about the intertwinments of a locality and another space. This is what this thesis is about. "La sedimentation du passage" renders a rigorous description of the numerous processes which bring the locality to the front line. / This study shows the description (Latour: 1987, 1999) of the participative actions of the actors involved in the network. The sedimentation of the passage reveals the repercussions of the mediations between the localities. This theorization activates, in other ways, the denationalization of actors, and, adds to the cultural construct of the network as well as to the possibilities of the Politic (Sassen: 2006). / This is an example of a networked knowledge production while, at the same time, and this may be of most importance, it is also an example of how today's reading of the locality deepens the necessity of participative actions in the mediations and mediatizations (Darbellay: 2006) of materialities in the contemporary globalization. The sedimentation of the passage allows one to read what circulation(s) are actually chosen to be materialized in and for the locality.

While bringing tremendous benefits to individuals worldwide, the proliferation of online social networks has also given rise to undesirable online harassment behavior. Although users can respond in various ways, little attention has been paid so far to the use of online coping strategies on social media, more specifically, how individuals respond to online harassment by using the available features on social media. This thesis sought to understand individuals' use of online coping strategies. This thesis aims to tackle these challenges to advance the understanding of whether, how, and why individuals use online coping strategies in response to online harassment. Essay 1 develops a typology of online coping strategies based on users' focus of response (i.e., self or initiator) and mode of response (i.e., avoidance or approach). This essay serves as a conceptual background for the two subsequent empirical studies (Essay 2 and Essay 3) that focus on two critical roles involved in online harassment (e.g., victims and bystanders). These two studies are conducted in the social media context. Essay 2 investigates whether and how individuals use online coping strategies in response to online harassment on social media. Results from a scenario-based experiment showed that victims would be more likely to adopt self-focused and approach strategies (e.g., seclusion, mediation, and reporting) when they perceived a high threat of the incident. Confidence in executing the platform functions would increase victims' use of the initiators-focused strategies in both modes (e.g., blocking and reporting) but reduce their use of self-focused avoidance strategy (e.g., seclusion). Trust in social media would lead victims to the self-focused approach strategy (e.g., mediation). Victims with the intensified fear of the incident would be more likely to use the self-focused and avoidance strategies (e.g., seclusion, mediation, and blocking). While Essay 2 focuses on the role of victims, Essay 3 concentrates on the role of bystanders and reporting strategy, which is one of the online coping strategies on social media that support bystanders' interventions. Essay 3 explains why individuals report witnessing online harassment. The results found that four contextualized factors (perceived emergency of the online harassment incident, perceived responsibility to report, perceived self-efficacy in using built-in reporting functions, and perceived outcome effectiveness of built-in reporting functions for tackling online harassment) are important factors for shaping bystander reporting interventions, while the presence of others as an inhibitor that discourages bystanders' willingness to help. This essay also found that socio- environmental and technological factors exert a significant effect on bystanders' willingness to intervene. In sum, this thesis contributes to the area of online harassment by breaking new ground for the study of users' prosocial responses to online harassment on social media. It not only furthers our understanding of online coping strategies but also provides valuable insights for practitioners to design effective coping features to combat online harassment.
