This article focuses on the launch by the Chinese company Huawei of ICT academies in sub-Saharan Africa (SSA), and Kenya especially. Existing literature shows contrasting findings concerning the impact of such formation and recruitment centres. Through high-level thematic and sentiment analyses, this article examines various Huawei accounts on...

Social networks are a platform for individuals and organizations to connect with each other and inform, advertise, spread ideas, and ultimately influence opinions. These platforms have been known to propel misinformation. We argue that this could be compounded by the recommender algorithms that these platforms use to suggest items potentially...

When spreading information over social networks, seeding algorithms selecting users to start the dissemination play a crucial role. The majority of existing seeding algorithms focus solely on maximizing the total number of reached nodes, overlooking the issue of group fairness, in particular, gender imbalance. To tackle the challenge of...

The aging population of European cities raises enormous challenges with regard to employment, pensions, health care and other age-related services. The housing preferences of the aging population are changing rapidly where more and more people want to live independent lives for as long as possible. At the same time governments need to reduce the...

In online communities, users frequently interact with strangers in order to buy and sell products, watch videos, educating themselves, and playing games. Establishing trust among strangers is essential for the functionality of these communities but challenging, as well. Online reputation systems effectively establish trust among strangers by...

This paper describes a framework that supports the physical prototyping of innovative interactive artifacts. Specifically, the framework allows designing, implementing, and testing “social products,” that is, physical artifacts able to interact with social media platforms such as Facebook, Twitter, Google+ and others. Since the target users of...

The present work constitutes the first stage of an ongoing research on the interaction between morphological characteristics of the urban fabric and the amount of social activity in such spaces. In order to analyze such correlation, the current research links together two different field of studies: Space Syntax on one side, for the...

This paper explores the sense of participation of a spatially distributed individual—in the intersections of physical and mediated networks. This sense is fundamental to an individuals’ experience as a participant in systems designed to this purpose including today’s social media and new media generations of infrastructures. Mediated networks...

This one-day workshop brings together HCI scholars and practitioners who share a common interest in understanding and exploring how we will be socially connected in the future. Central to our discussion will be the exploration of an interdisciplinary research agenda in social interaction design (SxD) that merges social networks and socially...

The infrastructure networks, including the Internet, telecommunication networks, electrical power grids, transportation networks (road, railway, waterway, and airway networks), gas networks and water networks, are becoming more and more complex. The complex infrastructure networks are crucial to our human society, and it has been a hot research ...

Social networks, as well as many other real-world networks, exhibit overlapping community structure. In this paper, we present formulas which facilitate the computation for characterizing the overlapping community structure of networks. A hypergraph representation of networks with overlapping community structure is introduced. Using the...

Enhancing the establishment and growth of spin-off firms from university is receiving an increased attention in local and regional policy today. University spin-off firms are typically in short of resources, reason why social networks play a vital role in their early growth. There is however a lack of understanding of the profile of these...

This paper proposes a new variant of the task allocation problem, where the agents are connected in a social network and tasks arrive at the agents distributed over the network. We show that the complexity of this problem remains NP-complete. Moreover, it is not approximable within some factor. In contrast to this, we develop an efficient greedy...

Resources contributed in ad hoc grids are volatile, unreliable and non-dedicated. Furthermore, resource owners contribute resources according to their own use and access policies. This phenomenon necessitates the study of the mechanisms that enable the ad hoc grid to modify its infrastructure in an autonomous way according to varying resource...

Integrated water resources management (IWRM) is regarded as an essential framework for the sustainable management of water resources. A key challenge in implementing IWRM involves coordinating the decisions between diverse actors with potentially conflicting interests. It is argued that the attainment of sustainable water management outcomes in...

Knowledge can be valorized in many different ways. University spin-offs have proven to be very effective as the knowledge generated in a university or research institute is directly translated into commercial activities. In addition, university spin-offs have played an important role in the economic and innovation growth of the region. While...

The social networks of low-income residents have been simultaneously described as supportive, strained, localized, and limited in providing access to necessary resources and information. Using a longitudinal qualitative approach, this study investigated the social networks of low-income women in one US high-poverty public housing project....

This paper proposes a new variant of the task allocation problem, where the agents are connected in a social network and tasks arrive at the agents distributed over the network. We show that the complexity of this problem remains NPhard. Moreover, it is not approximable within some factor. We develop an algorithm based on the contract-net...

As Online Social Networks (OSNs) become an intensive sub- ject of research for example in computer science, networking, social sci- ences etc., a growing need for valid and useful datasets is present. The time taken to crawl the network is however introducing a bias which should be minimized. Usual ways of addressing this problem are sampling...
