    As the annual number of migrants from sub-Saharan Africa to both the United States and Europe has grown for most years this decade, a Pew Research Center analysis of 2015 U.S. Census Bureau and Eurostat data finds that sub-Saharan immigrants in the U.S. tend to be more highly educated than those living in the United Kingdom, France, Italy and Portugal – Europe's historically leading destinations among sub-Saharan immigrants.In the U.S., 69% of sub-Saharan immigrants ages 25 and older in 2015 said they had at least some college experience. In the same year, the share in the UK who reported some college experience was 49%, while it was lower still in France (30%), Portugal (27%) and Italy (10%).Immigrants from sub-Saharan Africa living in the U.S. are also somewhat more likely to be employed than their counterparts in Portugal, France and Italy. In 2015, 92.9% of U.S.-based sub-Saharan immigrants said they had a paying job, compared with 84.9% in Portugal, 83.7% in France and 80.3% in Italy. Meanwhile, the share of sub-Saharan immigrants in the UK who are working (91.5%) was nearly equal to that in the U.S.The U.S., UK, France, Italy and Portugal are some of the top destinations of sub-Saharan migrants living outside of sub-Saharan Africa. As of 2015, however, more than two-thirds (69%) of migrants from sub-Saharan countries actually lived in other sub-Saharan African countries.Together, the U.S., UK, France, Italy and Portugal were home to more than half (57%) of the sub-Saharan migrant population living outside sub-Saharan Africa in 2015, according to global migrant population estimates from the United Nations. And the four European countries featured in this report accounted for roughly three-quarters (74%) of all sub-Saharan immigrants living in EU countries, Norway and Switzerland in the same year.Historically, sub-Saharan immigrants have made up small shares of the total population in the U.S., UK, France, Italy and Portugal – 3% or less in each country, as of 2015. But annual migration to the U.S. and Europe from sub-Saharan Africa rose most years this decade. In all, well more than a million sub-Saharans have migrated to the U.S. and to EU countries, Norway and Switzerland since 2010. Migration pressures for some sub-Saharans to leave Africa are expected to continue as the continent's population grows, young people struggle to find employment and protracted conflicts continue

    Micro Smart Micro-grid and Its Cyber Security Aspects in a Port Infrastructure

    Get PDF
    Maritime ports are intensive energy areas with a plenty of electrical systems that require an average power of many tens of megawatts (MW). Competitiveness, profits, reduction of pollution, reliability of operations, carbon emission trading are important energy related considerations for any port authority. Current technology allows the deployment of a local micro-grid of the size of tenths of MW, capable of islanded operation in case of emergency and to grant an increasing energy independency. Ownership of the grid permits a large flexibility on prices of energy sold inside the port, trading on local electric market and reduction of pollution. Renewable energy generation has a large impact on costs since features a low marginal cost. Unfortunately the smart grid is a critical asset within the port infrastructure and its intelligence is a high-level target for cyberattacks. Such attacks are often based on malicious software (malware), which makes use of a controlling entity on the network to coordinate and propagate. In this document, we will outline some features of a port smart grid and typical characteristics of cyber-attacks including potential ways to recognize it and suggestion for effective countermeasures

    A Spatial Model for the Needle Losses of Pine-Trees in the Forests of Baden-WĂŒrttemberg: An Application of Bayesian Structured Additive Regression

    Summary The data that are analysed are from a monitoring survey which was carried out in 1994 in the forests of Baden-WĂŒrttemberg, a federal state in the south-western region of Germany. The survey is part of a large monitoring scheme that has been carried out since the 1980s at different spatial and temporal resolutions to observe the increase in forest damage. One indicator for tree vitality is tree defoliation, which is mainly caused by intrinsic factors, age and stand conditions, but also by biotic (e.g. insects) and abiotic stresses (e.g. industrial emissions). In the survey, needle loss of pine-trees and many potential covariates are recorded at about 580 grid points of a 4 km × 4 km grid. The aim is to identify a set of predictors for needle loss and to investigate the relationships between the needle loss and the predictors. The response variable needle loss is recorded as a percentage in 5% steps estimated by eye using binoculars and categorized into healthy trees (10% or less), intermediate trees (10–25%) and damaged trees (25% or more). We use a Bayesian cumulative threshold model with non-linear functions of continuous variables and a random effect for spatial heterogeneity. For both the non-linear functions and the spatial random effect we use Bayesian versions of P-splines as priors. Our method is novel in that it deals with several non-standard data requirements: the ordinal response variable (the categorized version of needle loss), non-linear effects of covariates, spatial heterogeneity and prediction with missing covariates. The model is a special case of models with a geoadditive or more generally structured additive predictor. Inference can be based on Markov chain Monte Carlo techniques or mixed model technology

    The direct association of the multiple PDZ domain containing proteins (MUPP-1) with the human c-Kit C-terminus is regulated by tyrosine kinase activity

    AbstractWe have identified the multiple PDZ domain containing protein (MUPP-1 or MPDZ) as a novel binding partner of the human c-Kit. c-Kit binds specifically to the 10th PDZ domain of MUPP-1 via its C-terminal sequence. Furthermore, a kinase negative-mutant receptor interacted more strongly with MUPP-1 than the wild-type c-Kit. Strikingly, a constitutively activated c-Kit (D816V-Kit) did not bind to MUPP-1, although this oncogenic form retains the PDZ binding motif ‘HDDV’ at the C-terminal end. Deletion of V967 of c-Kit abolished binding to MUPP-1 and drastically reduced its tyrosine kinase activity, suggesting that the structure of the C-terminal tail of c-Kit influences its enzymatic activity

    Policy learning and adaptation in governance: A co-evolutionary perspective

    Get PDF
    This paper introduces the concepts and ideas that frame this special issue on co-evolution in governance, and their implications for policy learning and adaptation. It offers a brief overview of co-evolutionary approaches to governance and their elementary connections with systems theories, post-structuralism, institutionalism, and actor-network theory, and explores how they are connected to co-evolution in governance. Co-evolutionary approaches differ from other influential understandings of knowledge and learning in policy and governance. It furthermore presents a typology of learning in governance and systematically discusses how each type is affected by patterns of coevolution in governance

    No time for nonsense!:The organization of learning and its limits in evolving governance

    Get PDF
    This essay introduces and frames the contributions to the special issue on learning and co-evolution in governance. It develops the argument that learning, dark learning and non-learning are necessarily entwined in governance, moreover, entwined in a pattern unique to each governance configuration and path. What can be learned collectively for the common good, what kind of knowledge and learning can be strategically used and shamelessly abused, and which forms of knowledge remain invisible, intentionally and unintentionally, emerges in a history of co-evolution of actors and institutions, power and knowledge, in governance. Learning becomes possible in a particular form of management of observation, of transparency and opacity, where contingency is precariously mastered by governance systems expected to provide certainty for communities

    Upcoming Public Lecture: Nick Couldry on the Myth of Big Data

    Get PDF
    In the past year, the LSE Media Policy Project blog has contained a lot of discussion of “big data”. Stefan Strauss and Monica Horten wrote about the EU’s Data Protection Directive and the protection of personal data from mass collection by corporate interests. Oxford’s Ian Brown explained how big data is accessed by government agencies, and our Internet Governance Series covered recent attempts by Brazil and other countries to take control over where big data is stored and transferred. But have we been perpetuating flawed assumptions about the nature of big data
