| Abstract: | One of the key features of next-generation mobile networks is the ability to satisfy the requirements coming from different verticals. For satisfying these requirements, 5G networks will need to dynamically reconfigure the deployment of the network functions. However, the current deployments of mobile networks are experiencing difficulties in exhibiting the required flexibility. At the same time, the research on connectivity provisioning in use cases such as after-disaster scenarios or battlefields has converged towards the idea of Network-In-a-Box. This idea revolves around fitting all software and hardware modules needed by a mobile network in a single or a handful of physical devices. A Network-In-a-Box inherently offers a high level of flexibility that makes it capable of providing connectivity services in a wide range of scenarios. Therefore, the Network-In-a-Box concept represents an alternative approach for satisfying the requirements of next-generation mobile networks. In this survey, we analyze the state-of-the-art of Network-In-a-Box solutions proposed by academia and industry in the time frame starting from 1998 up to early 2017. First, we present the main use cases around which the concept has been conceived. Then, we abstract the common features of the Network-In-a-Box implementations, and discuss how different proposals offer these features. We then draw our conclusions and discuss possible future research directions, including steps required to reach an even higher level of flexibility. The aim of our analysis is twofold. On one hand, we provide a comprehensive view of the idea of Network-In-a-Box. On the other hand, through the analysis we present the features that future mobile networks should exhibit to achieve their design goals. In particular, we show how the Network-In-a-Box fosters the transition towards the next-generation mobile networks. |

(Helsingin yliopisto, 2014)Hearing is a versatile sense allowing us, among other things, to avoid danger and engage in pleasurable discussions. The ease with which we follow a conversation in a noisy environment is astonishing. Study I in this thesis used functional magnetic resonance imaging to explore the large-scale organization of speech and non-speech sound processing during a naturalistic stimulus comprised of an audio drama. Two large-scale functional networks processed the audio drama; one processed only speech, the other processed both speech and non-speech sounds. Hearing is essential for blind subjects. Anatomical and functional changes in the brains of blind people allow them to experience a detailed auditory world, compensating for the lack of vision. Therefore, comparing early-blind subjects brains to those of sighted people during naturalistic stimuli reveals fundamental differences in brain organization. In Study II, naturalistic stimuli were employed to explore whether one of the most distinguishing traits of the auditory system the left-lateralized responses to speech changes following blindness. As expected, in sighted subjects, speech processing was left-hemisphere dominant. Curiously, the left-hemisphere dominance for speech was absent or even reversed in blind subjects. In early-blind people, the senses beyond vision are strained as they try to compensate for the loss of sight; on the other hand, the occipital cortices are devoid of normal visual information flow. Interestingly, in blind people, senses other than vision recruit the occipital cortex. Additional to changes in the occipital cortex, the sensory cortices devoted to touch and hearing change. Data presented here suggested more inter-subject variability in auditory and parietal areas in blind subjects compared with sighted subjects. The study suggested that the greater the inter-subject variability of the network, the greater the experience-dependent plasticity of that network. As the prefrontal areas display large inter-subject spatial variability, the activation of the prefrontal cortex varies greatly. The variable activation might partly explain why the top-down influences of the prefrontal cortex on tactile discrimination are not well understood. In the fourth study, anatomical variability was assessed on an individual level, and transcranial magnetic stimulation was targeted at individually-chosen prefrontal locations indicated in tactile processing. Stimulation of one out of two prefrontal cortex locations impaired the subjects ability to distinguish a single tactile pulse from paired pulses. Thus, the study suggested that tactile information is regulated by functionally specialized prefrontal subareas.

(Svenska handelshögskolan, 2003)Economics and SocietyDespite thirty years of research in interorganizational networks and project business within the industrial networks approach and relationship marketing, collective capability of networks of business and other interorganizational actors has not been explicitly conceptualized and studied within the above-named approaches. This is despite the fact that the two approaches maintain that networking is one of the core strategies for the long-term survival of market actors. Recently, many scholars within the above-named approaches have emphasized that the survival of market actors is based on the strength of their networks and that inter-firm competition is being replaced by inter-network competition. Furthermore, project business is characterized by the building of goal-oriented, temporary networks whose aims, structures, and procedures are clarified and that are governed by processes of interaction as well as recurrent contracts. This study develops frameworks for studying and analysing collective network capability, i.e. collective capability created for the network of firms. The concept is first justified and positioned within the industrial networks, project business, and relationship marketing schools. An eclectic source of conceptual input is based on four major approaches to interorganizational business relationships. The study uses qualitative research and analysis, and the case report analyses the empirical phenomenon using a large number of qualitative techniques: tables, diagrams, network models, matrices etc. The study shows the high level of uniqueness and complexity of international project business. While perceived psychic distance between the parties may be small due to previous project experiences and the benefit of existing relationships, a varied number of critical events develop due to the economic and local context of the recipient country as well as the coordination demands of the large number of involved actors. The study shows that the successful creation of collective network capability led to the success of the network for the studied project. The processes and structures for creating collective network capability are encapsulated in a model of governance factors for interorganizational networks. The theoretical and management implications are summarized in seven propositions. The core implication is that project business success in unique and complex environments is achieved by accessing the capabilities of a network of actors, and project management in such environments should be built on both contractual and cooperative procedures with local recipient country parties.

(Elsevier Science, 2021)Environmental Science and Policy 123, 91-98An approach that has been suggested as potentially addressing the challenges of science-policy-interfaces (SPIs) is the mobilization of existing networks through a ‘network-of-networks’ (NoN) approach. This paper shares empirical findings from a mixed-method study, combining qualitative and quantitative data, that critically evaluates the ‘network-of-networks’ approach for SPIs. To establish whether and how a NoN can help existing networks act more effectively at the boundary of science and policy, we use the Eklipse Mechanism as a key example. We analyse the major characteristics of networks active in biodiversity-focused science-policy interactions, the potential roles and types of engagement of participants, and the major challenges faced by networks and individuals when acting at the boundaries of science and policy. Results suggest that the more diverse the actors involved, the more effective the SPI. While a formalized EU-level SPI for biodiversity is welcomed by most respondents, willingness and actual potential to contribute to such an entity differed amongst networks, highlighting that contributions to SPIs are highly dependent on individual and organizational capacities. The challenges faced by individuals and networks range from limited resources to effective communication and achieving meaningful impact even if the institutional context is unrewarding. To make a ‘network-of-networks’ model fully operational requires meeting the capacity building needs of networks, providing institutional support, and creating room for wider engagement.
