- There is an increasing trend of disastrous events during past decade with significant damage in terms of lives, infrastructure, economics and environment. Disastrous events are affecting communities worldwide and, apart for the actual and personal suffering involved, can fundamentally disrupt societal functions for many years. This is particularly the case in already vulnerable regions, which often require external assistance of various kinds. In order to reduce catastrophic effects of disasters, disaster mitigation measures and crisis reduction must be systematically planned and managed. This includes correct damage assessment, fast, efficient and prepared responses, adequate resource allocation and organisation of the relief processes. Obviously, the conditions and abilities to implement such measures are very different in various locations, where regions have particularly severe conditions. In this paper, we discuss crisis management in Sudan and highlight the need for national and regional disaster management processes and activities as well as general framework for the design of an efficient disaster management program in Sudan.

Tidskriftsartikel (refereegranskat)abstract
- The European Union has recently launched an ambitious plan to mitigate drastically, by 2025, the number of households lacking access to a 100 Mbps broadband connection through the subsidisation of the deployment of network infrastructure in rural areas. Decision makers such as governments and regulatory authorities therefore have to choose, among a pool of alternatives, a technology capable of delivering the required throughput on a large scale, based on a trade-off between the infrastructure costs and the subscribers’ perceived utility for each alternative. Such a trade-off is not simple, since there is no straightforward manner to rank the subscribers’ perceived utility against the network infrastructure cost. In this article, we propose a methodology based on real options, which outputs the value of each technology using multi-attribute value theory as an input, alongside the project’s risk and its costs.

Konferensbidrag (refereegranskat)abstract
- The European Union has been battling against the digital divide for several decades now when trying to mitigate the risk of social exclusion arising from the lack of broadband access, preventing citizens from full social and economic participation in the society. This has been done in the past by ensuring that a minimum set of services would be available to all end-users at an affordable price. However, various aspects of the rapid advances in technology, market developments and changes in user demand as well as the evolution of the telecommunications infrastructure (5G, IoT, Cloud, gigabit access, etc) increase the risk that citizens of rural areas are facing a severe risk of digital exclusion. To avoid this risk, the concept of subsidised rural networks was created by the European Commission. The idea as such is laudable, but the price tag remains unknown, which severely violates its implementability. In this article, based on the actual cost in a subsidised, but competitive, environment, we suggest a novel approach to realistically determine fair end-user's prices.

Risk assessment in 5G infrastructure deployment : an aid tool for estimating spectrum auction prices

Konferensbidrag (refereegranskat)abstract
- Risks are significant when implementing large-scale projects such as 5G. The higher the overall risk of the 5G project, the lower the operators’ willingness to invest in millimetre wave spectrum and vice-versa; i.e. the price of the spectrum should be negatively correlated with the overall project risk. In this paper, we propose an array-based method for estimating financial risks when introducing 5G and its correspondence with spectrum prices. The method is based on Monte Carlo simulations, for deriving an appropriate maximum value for the operator’ willingness to pay for a 5G license.

Rural Networks Cost Comparison Between 5G (Mobile) and FTTx (Fixed) Scenarios

- In this article we simulate the infrastructure costs for very fast networks in rural areas. FTTH technology has been around for at least a decade, but two brand new technologies are expected to launch commercially in the next couple of years: 5G and G. Fast. This could have a strong impact on infrastructure costs and the fulfilment of the European Union, rural coverage objectives. 5G seems to be very promising since LTE is not a reasonable solution for very fast networks. FTTC has so far not been a valid alternative, since for the last mile, the only options for FTTC has been ADSL and VDSL, which however cannot reach very fast data rates. G.Fast is three times faster than VDSL and has the advantage, comparing to FTTH, that the last mile infrastructure is already build in the form of copper local loop.

Satellite backhaul for macro-cells, as an alternative to optical fibre, to close the digital divide

Konferensbidrag (refereegranskat)abstract
- The lack of broadband access causes a serious risk of social exclusion, by preventing citizens from full social and economic participation in the society. To avoid this risk, the concept of subsidized rural networks was developed by the European Commission, in which an operator builds, maintains and operates a network (usually an open network) capable of providing at least a 100 Mbps connection to the subscribers; deployed in low density regions being publicly subsidized when unprofitable. In this article, we suggest a methodology to measure a realistic value for the average broadband used per subscriber at busy hour. We also present a simulation model for the backhaul infrastructure costs for very fast networks in rural areas to cover the last, and more expensive, 5% of the population, while comparing optical fibre with satellite for the middle mile from an economical and financial perspective.

Konferensbidrag (refereegranskat)abstract
- Due to a significant investment in digital infrastructure and a pro-innovation policy and regulatory framework, the Innovation Ecosystems in Nairobi, Dar es Salaam and Kampala have considerably expanded over the last five years, incorporating new national and international Innovation Stakeholders. This is important in the context of realising the objectives of National Development Plans, and addressing high levels of youth and graduate unemployment. This paper presents a sub-set of results from a comprehensive baseline analysis of Innovation Ecosystems in these cities with a focus on assessing the current level of ICT-related Collaboration, Innovation Absorption capacity and challenges to be addressed. In order to benefit from these developments, it is recommended that the public sector take a leadership role in establishing necessary mechanisms that will stimulate multi-stakeholder collaboration amongst existing Innovation Actors to foster a sustainable Collaborative Open Innovation and Entrepreneurial culture.

Tidskriftsartikel (refereegranskat)abstract
- Across Africa, Innovation and ICT entrepreneurship are increasingly recognised as important enablers of national and regional socio-economic growth. However, the level of skills capacity, indigenous entrepreneurial expertise and policy support varies considerably. This research study was informed by a semi-structured, moderated focus group involving five public and four education and research stakeholders from eight African Member States. It focused on identifying factors impacting on the current level of open innovation and ICT entrepreneurship in Africa. Organised in Lilongwe, Malawi on 08 May 2015 during IST-Africa Week 2015, a purposive approach was applied to identify the nine informants based on intensity sampling. The results highlighted six main factors: a) level of political will reflected by resource prioritisation; b) alignment with national development plans and associated funding priorities; c) level of understanding of strategic benefits by ministers and senior civil servants; d) level of awareness and sensitization of the general public, e) availability of national innovation and entrepreneurial expertise; and f) willingness and capacity to cooperate with other stakeholders to achieve common goals. Future research will capture perspectives from the private, societal and international donor sectors, and create and validate potential models/methodologies to address the challenges and opportunities identified in this study.

Konferensbidrag (refereegranskat)abstract
- This paper provides an analysis of the Innovation Ecosystems for three representative instances in East Africa: Nairobi (Kenya), Dar es Salaam (Tanzania) and Kampala (Uganda). The authors propose that to maximise the impact of innovation systems in a developing country context, innovation interventions (including ICT4D) must (a) facilitate shared, local ownership, with objectives driven by end-user community needs and taking account of previous interventions, good practices and socio-cultural norms; (b) be co-designed, co-created or adapted in consultation with key Innovation Stakeholders; (c) strengthen the capacity of local beneficiary and/or contributing Stakeholders and (d) address sustainability and wider socio-economic impact after the interventions ends. Innovation (including ICT4D interventions) that do not address these issues run the risk of damaging the local Innovation Ecosystem or breaching trust with local stakeholders, by not taking account of local socio-cultural differences or not adequately addressing expectations raised.

Digitalisering och organisering : Att skapa värde i det 21:a århundradet
- 2017
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- Förändringarna ger organisationer bättre förutsättningar än någonsin för att lyckas, men för att lyckas behöver man förstå och utnyttja dem. Vissa klarar det, andra inte. Att digitalisera framgångsrikt är inte enkelt.Den här boken visar hur organisationer skapar värde i en digitaliserad verklighet. Boken går igenom digitalisering med utgångspunkt i vad en organisation egentligen är och vad den behöver. Den spänner över mål, affärsmodeller, strategier, organisering, beslut och projekt. Tyngdpunkten ligger på hur man strukturerar för att få effektivare beslutshantering och mer framgångsrika projektgenomföranden. Eftersom beslut och project är grundpelare för att kunna använda digitaliseringen.Boken lämpar sig särskilt väl för kurser i företagsekonomi, industriell ekonomi och data- och systemvetenskap. Men den vänder sig till alla som vill förstå hur organisationer ska hantera och dra nytta av digitaliseringen.
