One of the most promising cement alternatives are geopolymer cements. The term “geopolymer” was mentioned for the first time by Davidovits and classifies all forms of inorganic polymeric material synthesised by chemical reaction of aluminosilicates and an alkaline activating solution. The production of geopolymer binder comprises in two main procedures: calcination and geopolymerisation. The synthesised geopolymer shows interesting characteristics like good mechanical properties, high strength and good durability. [less ▲]

In the cloud computing era, in order to avoid computational burdens, many organizations tend to outsource their com- putations to third-party cloud servers. In order to protect service quality, the integrity of computation results need to be guaranteed. In this paper, we develop a game theoretic framework which helps the outsourcer to maximize its pay- o while ensuring the desired level of integrity for the out- sourced computation. We de ne two Stackelberg games and analyze the optimal setting's sensitivity for the parameters of the model. [less ▲]

Das Konzept der Bewegten Schule geht auf den Schweizer Pädagogen Urs Illi zurück, der es Mitte der achtziger Jahre vor allem für den Primarbereich entwickelte (Illi, 1995). Ausgehend von einer medizinisch-gesundheitlichen (Bewegung als Gesundheitsressource) und entwick-lungs- und lerntheoretischen (Bewegung als zentrales Element der Kindesentwicklung, Bewe-gung als zusätzlicher Sinnes- und Erfahrungskanal) Begründung, geht es in diesem Konzept grundsätzlich darum, mehr Bewegung in die traditionelle „Sitzschule“ zu bringen. Am Projekt „Bewegter Unterricht in Luxemburg“ nahmen die SchülerInnen und Lehrkräfte der Grundschulen in Angelsberg, Larochette, Nommern, Lintgen und Vichten teil. An den Schulen Angelsberg, Larochette und Nommern fand im Untersuchungszeitraum von September 2014 bis Juni 2016 durchgehend Bewegter Unterricht statt. Diese Schulen werden im Weiteren als „Projektschulen“ bezeichnet. An den Schulen in Lintgen und Vichten wurde nicht „bewegt“ unterrichtet; diese Schulen dienten somit als Kontrollschulen. [less ▲]

Drawing upon the case of a polycentric cross-border metropolitan region in western Europe, this paper seeks to explore population mobility and housing market developments at the regional/international scale. Transnational linkages within this cross-border region intensified with the opening of the borders and the economic development of the Grand Duchy of Luxembourg as a global financial centre and a centre for European Institutions. Today about 44 per cent of employees working in Luxembourg live nearby across the Belgian, French or German border. One of the reasons is that housing prices in Luxembourg are nearly twice those in the neighbouring border regions. This increased mobility has an impact on the residents living in these areas. The research that guides this paper aims to detect perceptions of this phenomenon. Therefore principles of municipal policy, urban planning documents and the local media of three medium sized towns in the borderland are reviewed. Following a rather open research concept based on qualitative approaches (discourse analysis, grounded theory), findings reveal that locational advantages such as the proximity to Luxembourg do play a role; the perception that affordable housing is becoming increasingly critical leads to resentments that mix up with national stereotypes; while city officials report displacement due to the border-effect, they also illustrate the opportunities for regional development; at the same time property developers foster the internationalisation of urban planning. Pointing to the relational geographies that link these different places, the paper discusses the pros and cons of an umbrella concept that might be called ‘cross-border gentrification’. [less ▲]

We describe the clinical and whole genome sequencing (WGS) study of a non-consanguineous Italian family in which two siblings, a boy and a girl, manifesting a severe epileptic encephalopathy (EE) with skeletal abnormalities, carried novel SLC35A3 compound heterozy- gous mutations. Both siblings exhibited infantile spasms, associated with focal, and tonic vibratory seizures from early infancy. EEG recordings showed a suppression-burst (SB) pattern and multifocal paroxysmal activity in both. In addition both had quadriplegia, acquired microcephaly, and severe intellectual disability. General examination showed distal arthrog- ryposis predominant in the hands in both siblings and severe left dorso-lumbar convex scoliosis in one. WGS of the siblings-parents quartet identified novel compound heterozygous mutations in SLC35A3 in both children. SLC35A3 encodes the major Golgi uridine diphosphate N-acetylglucosamine transporter. With this study, we add SLC35A3 to the gene list of epilepsies. Neurological symptoms and skeletal abnormalities might result from impaired glycosylation of proteins involved in normal development and function of the central nervous system and skeletal apparatus.

The Egyptian judiciary has struggled against the executive authority for the past decades. This struggle has seen many losses and gains. It has paved the road for the judiciary to play a role in the constitutional process in the last five years. Many scholars present this judicial struggle as a conflict between the executive and the judiciary. However, the history of the internal conflicts among judges remains a mystery or is merely implied. Such conflicts have taken on various forms based on the political regime in power. As a result, this research argues that the struggle was not only between political regimes and the judiciary, but also expressed itself in an internal conflict among the members of the judiciary. This research is limited to the Republic period, lasting from 1952 to 2014. This period can be divided into seven different eras. This research, however, separates the history of the Republic into just six main eras, due to excluding the al-Sisi era (2014-18), given that he was still in power during the writing of this research. It is historically unfair to document incomplete periods, despite this constituting one of the worst periods in judicial history. Accordingly, this paper limits itself to presenting the internal conflicts witnessed during only six eras. These eras involve the transition period after the monarchy, also known as the Mohamed Naguib era (1952-54), the Nasser era (1954-70), the al-Sadat era (1970-80), the Mubarak era (1980-2011), the SCAF era (2011-12), the Mohamed Morsi era (2012-13), and the transition period following the military coup, also known as the Mansur era (2013-14).

This article identifies ethnic network effects among temporary migrants in the UK. Using microdata from Understanding Society and the UK Census, the empirical results show that ethnic networks change the individual probability for circular migration. These effects are strong and significant only for some ethnicities, when controlling for a set of socio-economic characteristics 10 and when adding spatial variability. [less ▲]

Europe’s sovereign debt crisis and the accompanying national bank crises in the European Union brought bank regulation and supervision to the top of the EU policy agenda. In a few short years, we have witnessed a ‘great leap forward’ for European integration marked by over a dozen pieces of EU legislation shaping the operation of banks, rules on bank capital, reconfigured supervisory agencies, and Banking Union. The significance of these measures lies however, in the fact that they constitute the most dramatic transfer of policy-making powers to the European level since the start of Economic and Monetary Union in 1999. This volume addresses the three main political battles behind the adoption of these new regulatory and supervisory policies. First, it examines divisions among states, both according to their domestic institutional structures, including distinct financial systems, as well as their creditor or debtor status in the crisis. Second, it studies the battle over national versus supranational jurisdiction. Third, it explores the conflictual process of policy learning and the activation of epistemic communities who claim competence to address the crisis. [less ▲]

In a single case study, we show how a conversation analysis (CA) approach can shed light onto the sequential unfolding of human-robot interaction. Relying on video data, we are able to show that CA allows us to investigate the respective turn-taking systems of humans and a NAO robot in their dialogical dynamics, thus pointing out relevant differences. Our fine grained video analysis points out occurring breakdowns and their overcoming when humans and a NAO-robot engage in a multimodally uttered multi-party communication during a sports guessing game. Our findings suggest that interdisciplinary work opens up the opportunity to gain new insights into the challenging issues of human robot communication in order to provide resources for developing mechanisms that enable complex HRI.

L’historienne Laure Verdon caractérise « tout acte ou parole qui rompt le tissu social et porte atteinte à l’ordre » comme violence. De plus, le chercheur « doit s’interroger sur les formes qu’a pris la violence au fil des époques et sur le rapport que les hommes entretiennent avec elle » (Éloïse Adde, 2012). Parmi d’autres voies pour saisir cette variation historique et culturelle de la perception de la violence, nous proposons une analyse minutieuse des comptes des officiers de justice. Contrairement aux règlements, aux lois ou encore aux sources judiciaires qui expriment le fonctionnement théorique de la justice, ces comptes, de par leur caractère administratif, livrent une image réelle des crimes commis. Bien que le terme « violence » n’apparaisse jamais en tant que tel dans ces sources, les crimes et délits mentionnés dans les comptes sont considérés comme tels car ils représentent toujours une forme de violence contre le tissu social ou/et l’ordre établie. Leur présence dans ces sources et leur usage en justice permettent de projeter la conception de la violence pour une époque concrète en nous informant sur la perception quotidienne que les contemporains - surtout les justiciers - en avaient envers. En outre, la variété des cas permet de moduler cette compréhension et de proposer une lecture fine du phénomène. Conservés presque dans leur totalité pour la période de 1525 à 1630, les livres de comptes rédigés dans la prévôté de Luxembourg, une des plus grandes du duché, consistent une source primordiale pour entamer une telle recherche.
