Growth in scientific productivity over the 20th century resulted significantly from three major countries in European science—France, Germany, and the United Kingdom. We chart the development of universities and research institutes that bolster Europe’s key position in global science. We uncover both stable and dynamic patterns of productivity in the fields of STEM, including health, over the twentieth century. On-going internationalization of higher education and science has been accompanied by increasing competition and collaboration. Despite policy goals to foster innovation and expand research capacity, policies cannot fully account for the differential growth of scientific productivity we chart from 1975 to 2010. Our neoinstitutional framework facilitates explanation of differences in institutional settings, organizational forms, and organizations that produce the most European research. We measure growth of published peer-reviewed articles indexed in Thomson Reuters’ Science Citation Index Expanded (SCIE). Organizational forms vary in their contributions, with universities accounting for nearly half but rising in France; ultrastable in Germany at four-fifths, and growing at around two-thirds in the UK. Differing institutionalization pathways created the conditions necessary for continuous, but varying growth in scientific productivity in the European center of global science. The research university is central in all three countries, and we identify organizations leading in research output. Few analyses explicitly compare across time, space, and different levels of analysis. We show how important European science has been to overall global science productivity. In-depth comparisons, especially the organizational fields and forms in which science is produced, are crucial if policy is to support research and development. [less ▲]

In The Century of Science, a multicultural, international team of authors examines the global rise of scholarly research in science, technology, engineering, mathematics, and health (STEM+) fields. At the beginning of the 20th century, the global center-point of scientific productivity was about half way between Western Europe and the U.S., in the North Atlantic. Then, the center moved steadily westward and slightly southward—reflecting the burgeoning science capacity of the U.S. supported by America’s thriving public and private universities, technological innovation, and overall economic growth. After WWII, this began to change as the course of the world’s scientific center of gravity turned and for the next 70 years traveled eastward, the direction it still travels, especially due to the rise of China and other prolific East Asian countries, such as Japan, Taiwan, and South Korea. Europe continues to be the center of global science. Focusing on these developments, this volume provides historical and sociological understandings of the ways that higher education has become an institution that, more than ever before, shapes science and society. Case studies, supported by the most historically and spatially extensive database on STEM+ publications available, of selected countries in Europe, North America, East Asia, and the Middle East, emphasize recurring themes: the institutionalization and differentiation of higher education systems to the proliferation of university-based scientific research fostered by research policies that support continued university expansion leading to the knowledge society. Growing worldwide, research universities appear to be the most legitimate sites for knowledge production. Countries like France, Germany, the United Kingdom, the United States, and Japan began the 20th century with prerequisites in place to realize the emerging model of university-based research. Over the past several decades, China, South Korea, and Taiwan, with different historical legacies and conflicts in education and research policy, have witnessed explosive growth, sustained by public and private funds. Qatar recently embarked on an ambitious government-driven effort to develop a world-class university sector and cultivate academic STEM+ research from scratch. These more recent entrants to the global scientific enterprise pose the question whether it is possible to leapfrog across decades, or even centuries, of cultivating university systems, to compete globally. Simultaneously with international and regional competition, world-leading science increasingly implies collaboration across cultural and political borders as global scientific production and networking continue to rise exponentially. This volume’s case studies offer new insights into how countries develop the university-based knowledge thought fundamental to meeting social needs and economic demands. Despite repeated warnings that universities would lose in relevance to other organizational forms in the production of knowledge, our findings demonstrate incontrovertibly that universities have become more—not less—important actors in the world of knowledge. The past hundred years have seen the global triumph of the research university. [less ▲]

The recent expansion of Islamic banks raises questions on its economic implications. The aim of this paper is to investigate the impact of Islamic banking development on access to credit. We combine data from a unique hand-collected database that covers Islamic banks with firm-level data covering developing and emerging countries over the period of 2006 to 2009. We find that Islamic banking development has overall no impact on credit constraints, while banking development and conventional banking development alleviate obstacles to financing. However Islamic banking development exerts a positive impact on access to credit when conventional banking development is low. Hence we support the view that Islamic banking does not overall alleviate obstacles to financing, but it can act as substitute to conventional banking. [less ▲]

Non-technical losses (NTL) occur during the distribution of electricity in power grids and include, but are not limited to, electricity theft and faulty meters. In emerging countries, they may range up to 40% of the total electricity distributed. In order to detect NTLs, machine learning methods are used that learn irregular consumption patterns from customer data and inspection results. The Big Data paradigm followed in modern machine learning reflects the desire of deriving better conclusions from simply analyzing more data, without the necessity of looking at theory and models. However, the sample of inspected customers may be biased, i.e. it does not represent the population of all customers. As a consequence, machine learning models trained on these inspection results are biased as well and therefore lead to unreliable predictions of whether customers cause NTL or not. In machine learning, this issue is called covariate shift and has not been addressed in the literature on NTL detection yet. In this work, we present a novel framework for quantifying and visualizing covariate shift. We apply it to a commercial data set from Brazil that consists of 3.6M customers and 820K inspection results. We show that some features have a stronger covariate shift than others, making predictions less reliable. In particular, previous inspections were focused on certain neighborhoods or customer classes and that they were not sufficiently spread among the population of customers. This framework is about to be deployed in a commercial product for NTL detection. [less ▲]

In this work, a novel symbol-level precoding scheme is proposed, for managing the multi-user interference in the forward downlink channel of a multi-beam satellite system. Besides exploiting the constructive interference effect, the proposed scheme aims at improving the robustness of the transmitted signals to the non-linear distortions of practical satellite systems. This is done by reducing the imbalances between the instantaneous power transmitted by the multiple antennas, which are detrimental in non-linear systems. More specifically, this work proposes a symbol-level precoding scheme performing the minimization of the spatial peak-to-average power ratio, under Quality-of-Service constraints. An iterative algorithm is proposed to solve the related optimization problem. Numerical results are presented to assess the performance of the proposed scheme, which outperforms the state of the art symbol-level precoding techniques in terms of spatial peak-to-average power ratio across the transmitting antennas.

Le domaine de la protection de la jeunesse porte sur la prise en charge de situations familiales de vulnérabilité qui peuvent engendrer des impacts négatifs sur le développement de l'enfant. A l'inverse, la notion de résilience permet la perspective sur une trajectoire familiale qui compense le danger pour le développement de l'enfant et le fonctionnement familial. La thèse est développée dans le but d'offrir un cadre de réflexion aux réponses élaborées aussi bien par les services d'aides que par les familles elles-mêmes face aux difficultés rencontrées, tenant compte des particularités liées au contexte luxembourgeois.
