This book is intended to assist organisations in getting a grip on the factors influencing EA implementation and gaining a deeper understanding of why things happen the way they do in the practice of EA. It is a comprehensive and definitive resource that is useful to both business professionals and academics. The book presents an approach for the development, implementation, or institutionalisation of EA that is independent of any method or other architecture frameworks. It can be applied directly using a realistic selection of organizational variables. The approach has two distinctive features that support EA, even in complex environments: From both technical and non-technical perspectives, it identifies influencing factors and how they manifest in the practice of EA in an organization It offers linear and practical mechanisms for developing and implementing EA to fortify the practice of the concept in an organisation This approach represents a significant contribution to EA. Starting with descriptions for EA, the book offers deepened models and frameworks for the development and implementation of EA at the domain level. It also covers factors upon which a model is built for the institutionalisation of the concept. Additionally, the book discusses the implications of EA for sponsors, architects, and other stakeholders responsible for EA development, implementation, and institutionalisation.

There have been several stand-alone articles and chapters that have gone into this area and consequently paving way for this important work. In this volume we cover, among others, the political economy of social media journalism, theoretical perspectives, start-ups, and country case studies. This book provides insights into the complexity of the appropriation and incorporation of social media into the traditional news media mix in African and African journalism. The main aim is to examine what, how, and to what extent is social media reconfiguring and restructuring journalistic practice as we know it. The blurring of social media content and news media content requires a closer investigation. If social media is reconfiguring journalism as a craft, to what extent is this configuring aiding or undermining the profession. Hence, employing a cross-section of methodological approaches, country case studies, and theoretical paradigms, the introductory chapter assesses trends and opportunities associated with the increasingly pervasive use of social media. The chapter promotes a new conceptualization of a certain type of journalism which is specifically born and thrives through social media applications in present-day sub-Saharan Africa. This introductory chapter theorizes social media driven journalism, maps the changing structure of journalism, and looks at new forms of journalisms enabled by advent and wide use of social media applications. The chapter concludes with giving individual chapter summaries and how they contribute to the concept of social media driven journalism and how that is shaping journalism cultures across Africa.

Diasporic media here refers to media organisations established and run by Zimbabweans living outside Zimbabwe. Most of these Zimbabweans are former journalists who fled the country due to the constricted democratic space. These diasporic news media organisations cover issues about Zimbabwe and Zimbabweans in the diaspora. A secondary interest advanced in this study is the normative role played by diasporic media in mediating Zimbabwe’s complex political environment. The study addresses three critical questions. First, how is diaspora media employing social media for its news value chain? Second, what can be derived from the content of the selected case in determining the normative role of the diasporic media? And third, to what extent is the business model of diaspora media sustainable. In order to understand the phenomenon of the diasporic media, we analyse Nehanda Radio through a qualitative study that investigates the relationship between social media and diasporic media outlets. Nehanda Radio prides itself as a Zimbabwean radio station that provides 24-hour running news on their website and during broadcasts. It also claims to provide breaking news as it happens via its popular e-mail alert system which listeners and readers can subscribe to. Methodologically, we rely on desktop study. Theoretically, we use a combination of agenda setting and the political economy.

We introduce two ideas: the notion of ‘in[formal]ity’ as a dialectic whole – replacing the dichotomy of formal vs. informal – and the phenomenon of grounded architectural practice (GAP), which is understood as a material manifestation of the notion of ‘in[formal]ity’. These two ideas require architects to appreciate informal spatial practice as a legitimate and constructive form of urbanism. We employ socio-technical transition theory as a framework for our exploration of GAP. This theory explicates the interdependencies between complex and multi-layered interactions in socio-technical transitions, and maps these onto a single hierarchical framework, referred to as the multi-level perspective. We then employ activity theory to allow for the mapping of the actions of local government as well as informal settlement residents on an equal footing, which in itself is a step towards spatial justice. Engaging in GAP enables architects to consider their own practice from within the context of intervention and develop an understanding of both the socio-technical regime of local government and the informal spatial practice of residents. This understanding provides architects with the opportunity to promote spatial justice by advocating on behalf of the residents in support of informal settlement upgrading, according to residents’ priorities. In doing so, architects’ involvement with residents and their informal spatial practice is extended even further, fostering an ongoing process of expansive learning with the potential to direct architectural practice towards spatial justice.
