Administrative capacity and long-term policy making at the Icelandic local level

Leach and Wilson (2002) identified four key tasks of local government leaders. Building on their initiative, this paper examines the task of developing strategic and policy direction at the Icelandic local level from the viewpoint of the Icelandic mayor. In addition, it explores the administrative capacity of Icelandic local governance. Individuals occupying mayoral positions in Iceland always serve as heads of administration. At times, mayors are council members (political mayors), while other times they are hired based on their professional skills (manager-mayors). The findings suggest that mayors of both types play crucial roles in long-term policy making. However, the study shows that the daily work of manager-mayors is often hindered by fragmentation and lack of specialisation within the administration as well as by the laymen rule upon which the council-committee system is based.Peer ReviewedRitrýnt tímari

Foggy clouds and cloudy fogs: a real need for coordinated management of fog-to-cloud computing systems

The recent advances in cloud services technology are fueling a plethora of information technology innovation, including networking, storage, and computing. Today, various flavors have evolved of IoT, cloud computing, and so-called fog computing, a concept referring to capabilities of edge devices and users' clients to compute, store, and exchange data among each other and with the cloud. Although the rapid pace of this evolution was not easily foreseeable, today each piece of it facilitates and enables the deployment of what we commonly refer to as a smart scenario, including smart cities, smart transportation, and smart homes. As most current cloud, fog, and network services run simultaneously in each scenario, we observe that we are at the dawn of what may be the next big step in the cloud computing and networking evolution, whereby services might be executed at the network edge, both in parallel and in a coordinated fashion, as well as supported by the unstoppable technology evolution. As edge devices become richer in functionality and smarter, embedding capacities such as storage or processing, as well as new functionalities, such as decision making, data collection, forwarding, and sharing, a real need is emerging for coordinated management of fog-to-cloud (F2C) computing systems. This article introduces a layered F2C architecture, its benefits and strengths, as well as the arising open and research challenges, making the case for the real need for their coordinated management. Our architecture, the illustrative use case presented, and a comparative performance analysis, albeit conceptual, all clearly show the way forward toward a new IoT scenario with a set of existing and unforeseen services provided on highly distributed and dynamic compute, storage, and networking resources, bringing together heterogeneous and commodity edge devices, emerging fogs, as well as conventional clouds.Peer ReviewedPostprint (author's final draft

A survey on mobility-induced service migration in the fog, edge, and related computing paradigms

The final publication is available at ACM via http://dx.doi.org/10.1145/3326540With the advent of fog and edge computing paradigms, computation capabilities have been moved toward the edge of the network to support the requirements of highly demanding services. To ensure that the quality of such services is still met in the event of users’ mobility, migrating services across different computing nodes becomes essential. Several studies have emerged recently to address service migration in different edge-centric research areas, including fog computing, multi-access edge computing (MEC), cloudlets, and vehicular clouds. Since existing surveys in this area focus on either VM migration in general or migration in a single research field (e.g., MEC), the objective of this survey is to bring together studies from different, yet related, edge-centric research fields while capturing the different facets they addressed. More specifically, we examine the diversity characterizing the landscape of migration scenarios at the edge, present an objective-driven taxonomy of the literature, and highlight contributions that rather focused on architectural design and implementation. Finally, we identify a list of gaps and research opportunities based on the observation of the current state of the literature. One such opportunity lies in joining efforts from both networking and computing research communities to facilitate future research in this area.Peer ReviewedPreprin

This ensures that users' resource-intensive tasks are always served by the most suitable FNs in their vicinity. However, since MM decisionmaking requires control information which is difficult to predict accurately a-priori, such as the users' mobility patterns and the dynamics of the FNs, researchers have started to shift their attention towards MM solutions based on online learning. Motivated by this approach, in this paper, we consider a bandit learning model to address the mobility-induced FN selection problem, with a particular focus on scenarios with a high FN density. Following this approach, a software agent implemented within the user's device learns the FNs' delay performances via trial and error, by sending them the user's computation tasks and observing the perceived delay, with the goal of minimizing the accumulated delay. This task is particularly challenging when considering a high FN density, since the number of unknown FNs that need to be explored is high, while the time that can be spent on learning their performances is limited, given the user's mobility. Therefore, to address this issue, we propose to limit the number of explorations to a small subset of the FNs. As a result, the user can still have time to be served by the FN that was found to yield the lowest delay performance. Using real world mobility traces and task generation patterns, we found that it pays off to limit the number of explorations in high FN density scenarios. This is shown through significant improvements in the cumulative regret as well as the instantaneous delay, compared to the case where all newly-appeared FNs are explored.Peer ReviewedPostprint (author's final draft

Dutiful citizen or a pragmatic professional? Voluntary retirement of Icelandic local councillors

This article explores the working conditions of Icelandic local councillors in relation to voluntary retirement from the council. In the past three elections, the turnover in councils has been very high, with approximately six out of every 10 council members being new recruits at the beginning of each term. The turnover has also highlighted possible gender issues, as more women than men (proportionally) leave the council after their first term. The findings reveal a significant difference between the councillors who plan to stay and those who opt to leave. This is in relation to the local authorities’ population size, satisfaction with remuneration, and seniority in the council. Thus, councillors in larger municipalities or councillors satisfied with their remuneration are more likely to run for council versus councillors from smaller municipalities and those less happy with their remuneration. Seniority is also a decisive factor, as the majority of all councillors leave after the first term. Significant differences were not found between the female and male councillors in relation to voluntary retirement. However, gendered differences were found in relation to institutional position and working conditions, suggesting a gender-based division of labour in local councils.The author is grateful to the University of Iceland Research Fund for a grant rewarded to the survey this paper is based on.Peer Reviewe

The theoretical and practical dilemma of creating a new organisational design for a municipality using sub-municipal units

Organisational design is an important factor in determining the survival of organisations. The organisation and design of municipalities and local government is no exception to that rule. Concluding an amalgamation process indicates that a new organisational design must be introduced. The rule of thumb is that such proposals do not deviate much from the organisational tradition of local government in country or region in question. However, there are exceptions to that rule. Following an amalgamation of four Icelandic municipalities in 2020 a new organisational design was introduced. Consequently, a municipality with submunicipal units was established for the first time in Iceland. Submunicipal councils with a mixture of directly and indirectly elected members were created in each of the previous four separate municipalities, creating a second administrative tier within the municipality. The aim of the new design was to address problems inherent in amalgamation processes such as alienation of smaller communities within the new municipality often resulting in feelings of low levels of democratic legitimacy in many newly established municipalities. Another aim was to ensure that the municipal administration and services were organised aligned with local needs. The study aims to shed light on both the theoretical and practical dilemma of creating a new organisational design for a new municipality by using an interdisciplinary approach combining organisational theory with theory and studies on local government. Therefore, the study explores how successful this new municipal design is through the development of the municipal organisational chart, and survey results.Peer reviewe

Autonomy or integration: Historical analysis of the debate on the purpose of Icelandic local self-government

An ongoing debate on the purpose of local self-government in Iceland has been simmering mainly between those who believe that local authorities should amalgamate in order to assume more responsibilities and those who believe that local autonomy, understood as the right of citizens to govern their own jurisdictions, should not be weakened. The purpose of this study is to discuss the role of local self-government in Iceland from these two very different perspectives by situating it within the context of the Nordic model of local self-government. This study’s findings reveal that the Icelandic central government has successfully introduced functional reforms at the local level over the past 25 years, but it has not been as successful in initiating territorial reforms. The findings also show that conflict between the ideologies of the traditional autonomPeer Reviewe

Studies of Lithium-Oxygen Battery Electrodes by Energy- Dependent Full-Field Transmission Soft X-Ray Microscopy

Energy‐dependent full‐field transmission soft X‐ray microscopy is a powerful technique that provides chemical information with spatial resolution at the nanoscale. Oxygen K‐level transitions can be optimally detected, and we used this technique to study the discharge products of lithium‐oxygen batteries, where this element undergoes a complex chemistry, involving at least three different oxidation states and formation of nanostructured deposits. We unambiguously demonstrated the presence of significant amounts of superoxide forming a composite with peroxide, and secondary products such as carbonates or hydroxide. In this chapter, we describe the technique from the fundamental to the observation of discharged electrodes to illustrate how this tool can help obtaining a more comprehensive view of the phenomena taking place in metal air batteries and any system involving nanomaterials with a complex chemistry
