Labour Markets in EMU - What has changed and what needs to change

This paper reviews theoretical and empirical aspects of the interaction between Europe's Economic and Monetary Union and recent labour market developments. Policies meant to increase and stabilize labour incomes also tend to reduce employment and productivity, theory suggests that the latter effects should be sharper and more relevant within an integrated market area, making it harder for National policy makers to address the consequences of financial and other market imperfections. Empirical patterns of policy and outcome indicators in member and non-member countries of EMU are consistent with that theoretical mechanism. In the data, tighter economic integration is associated with better employment performance, substantial deregulation, sharper disemployment effects of remaining regulatory differences, and somewhat higher inequality and larger private financial market volume..labour market, monetary union, unemployment, employment, labour income, Bertola

Do institutions matter for technological change in transition economies? The case of the Russia's 89 regions and republics

We explore the impact of institutions on technological change in a transition economy. We use regional panel data for Russia's 89 regions and republics during the period of recovery and growth from 1998 to 2004 to show the impact of large variation in institutional development, ranging from full enforcement of property rights in the Northwest to red belt Communist regimes in the southeast. We find an unambiguous relationship between strong and sustained institutional development and technological change. We provide one model proxying the quality of institutions by the investment risk rating compiled by the rating agency ExpertRA Regions

Impact of Nucleon-Nucleon Bremsstrahlung Rates Beyond One-Pion Exchange

Neutrino-pair production and annihilation through nucleon-nucleon bremsstrahlung is included in current supernova simulations by rates that are based on the one-pion-exchange approximation. Here we explore the consequences of bremsstrahlung rates based on a modern nuclear interactions for proto-neutron star cooling and the corresponding neutrino emission. We find that despite a reduction of the bremsstrahlung emission by a factor of 2-5 in the neutrinospheric region, models with the improved treatment exhibit only $\lesssim$5% changes of the neutrino luminosities and an increase of $\lesssim$0.7 MeV of the average energies of the radiated neutrino spectra, with the largest effects for the antineutrinos of all flavors and at late times. Overall, the proto-neutron star cooling evolution is slowed down modestly by $\lesssim$0.5-1 s.Comment: 11 pages, 7 figures, minor changes and additions, to appear in Phys. Rev.

On the Distributability of Mobile Ambients

Modern society is dependent on distributed software systems and to verify them different modelling languages such as mobile ambients were developed. To analyse the quality of mobile ambients as a good foundational model for distributed computation, we analyse the level of synchronisation between distributed components that they can express. Therefore, we rely on earlier established synchronisation patterns. It turns out that mobile ambients are not fully distributed, because they can express enough synchronisation to express a synchronisation pattern called M. However, they can express strictly less synchronisation than the standard pi-calculus. For this reason, we can show that there is no good and distributability-preserving encoding from the standard pi-calculus into mobile ambients and also no such encoding from mobile ambients into the join-calculus, i.e., the expressive power of mobile ambients is in between these languages. Finally, we discuss how these results can be used to obtain a fully distributed variant of mobile ambients.Comment: In Proceedings EXPRESS/SOS 2018, arXiv:1808.08071.

Supporting Dynamic Service Composition at Runtime based on End-user Requirements

Network-based software application services are receiving a lot of attention in recent years, as observed in developments as Internet of Services, Software as a Service and Cloud Computing. A service-oriented computing ecosystem is being created where the end-user is having an increasingly more active role in the service creation process. However, supporting end-users in the creation process, at runtime, is a difficult undertaking. Users have different requirements and preferences towards application services, use services in different situations and expect highly abstract mechanisms in the creation process. Furthermore, there are different types of end-users: some can deliver more detailed requirements or can be provided with more advanced request interface, while others can not. To tackle these issues and provide end-users with personalised service delivery, we claim that runtime automated service composition mechanisms are required. In this paper we present the DynamiCoS framework, which aims at supporting the different phases required to provide end-users with automatic service discovery, selection and composition process. In this paper we also present the developed prototype and its evaluation

Uncomplicating the business of repositories

In this presentation, we discuss how our library runs our repository in production to meet the needs of our “business” as efficiently as possible. We have an interest in limiting the number of digital platforms we manage, for the purposes of sustainability and efficiency, but we must also consider how well a general platform can meet specific user needs. A governance group of administrators, in conference with stakeholders and developers, seeks to find the best way to accommodate each collection or functional need, with an eye to minimizing technical complexity, offering stakeholders self-serve options when possible, and maintaining a single canonical copy of each object. We will present some case studies of how material has been handled in our developing digital ecosystem, where preservation and access sometimes present conflicting priorities. We are exploring how our repository can best evolve to support our aims of making data and documents freely available

More Than a Pretty Interface: The Louisiana Digital Library as a Data Hub

The Louisiana Digital Library (LDL) is an online platform for libraries, museums, archives, and historical organizations across the state. The books, manuscripts, oral histories, maps, and photographs held in the LDL showcase the cultural resources of Louisiana. The interface enables users to discover materials through search and browse, and to view and interact with these materials. The metadata about these items is also a great asset. When explored in their entirety, the data held in the LDL is as valuable as the digital facsimiles. The LDL may be conceptualized as a data hub, a place to gather and share the metadata of the participating institutions. Open data is a growing trend in archives and special collections, enabling new types of interactions with collection material. Exposing the data held in digital libraries, in ways that extend beyond traditional digital library discovery and access, opens pathways for researchers to investigate complex questions. This paper contextualizes the field of open data in historical institutions, and explores uses for downloaded metadata from the LDL
