Context matters in social entrepreneurship, and it matters a lot. Social entrepreneurs are deeply entrenched in the context where they operate: they respond to its challenges, are shaped by it, and attempt to shape it in turn. The purpose of this paper is to discuss how social entrepreneurship in Africa is still understood within the scope of Western theories, without much consideration for local variations of the commonly shared archetype of social entrepreneurship or for how African norms, values and beliefs may shape our common understanding of this phenomenon.

The authors survey the often-neglected literature on social entrepreneurship in Africa and bring it together in this paper to discuss – also from the vantage point of their own experience and research in diverse African countries – how important assumptions in the social entrepreneurship literature are confirmed, enriched or challenged by key dimensions of African contexts.

Four important themes in the literature on social entrepreneurship in Africa emerged – institutions, embedding values, entrepreneurial behaviour and bricolage and scaling impact – each with its own considerations of how African contexts may challenge predominant assumptions in the extant social entrepreneurship literature, as well as implications for future research.

The authors uncover ways in which the peculiarities of the African context may challenge the underlying – and mostly implicit – assumptions that have shaped the definition and analysis of social entrepreneurship. They end by offering their understanding of social entrepreneurship and its concomitant dimensions in Africa as a stepping stone for advancing the field in the continent and beyond.

The Cloud of Things (IoT) that refers to the integration of the Cloud Computing (CC) and the Internet of Things (IoT), has dramatically changed the way treatments are done in the ubiquitous computing world. This integration has become imperative because the important amount of data generated by IoT devices needs the CC as a storage and processing infrastructure. Unfortunately, security issues in CoT remain more critical since users and IoT devices continue to share computing as well as networking resources remotely. Moreover, preserving data privacy in such an environment is also a critical concern. Therefore, the CoT is continuously growing up security and privacy issues. This paper focused on security and privacy considerations by analyzing some potential challenges and risks that need to be resolved. To achieve that, the CoT architecture and existing applications have been investigated. Furthermore, a number of security as well as privacy concerns and issues as well as open challenges, are discussed in this work.

In this article we aim to understand how the network formed by fitness tracking devices and associated apps as a subset of the broader health-related Internet of things is capable of spreading information.

The authors used a combination of a content analysis, network analysis, community detection and simulation. A sample of 922 health-related apps (including manufacturers' apps and developers) were collected through snowball sampling after an initial content analysis from a Google search for fitness tracking devices.

The network of fitness apps is disassortative with high-degree nodes connecting to low-degree nodes, follow a power-law degree distribution and present with low community structure. Information spreads faster through the network than an artificial small-world network and fastest when nodes with high degree centrality are the seeds.

This capability to spread information holds implications for both intended and unintended data sharing.

The analysis confirms and supports evidence of widespread mobility of data between fitness and health apps that were initially reported in earlier work and in addition provides evidence for the dynamic diffusion capability of the network based on its structure. The structure of the network enables the duality of the purpose of data sharing.
