The integration of refugees in Turkey has been realized in the field with the help of DGMM (Directorate General on Migration Management), Kızılay and UNHCR mainly, and by many more international and non-governmental organizations that have supported refugees by answering their short-term needs such as giving them cards for shopping, clothes, preparing them for winter (“winterization”) and providing educational assistance. I conducted 15 interviews with state officials, various NGOs and a few refugees. During my research many interesting points about integration policies (to-be-formed) at the moment in Turkey were discovered. One interesting finding was that the state officials do not like to use the word “integration”, as it is reminiscent of the way Turkish migrant workers were treated in Germany, where assimilation and integration were understood as the same concept. I use the term “temporary integration” for the case of all refugees, but this paper will focus mostly on the Syrians’ case. Within the context of temporariness, this paper’s central attention will be the educational integration of Syrian refugees in Turkey. I argue in the paper that the temporariness and the nostalgia with the Ottoman past are two main elements mostly present regarding the educational integration of Syrians in Turkey. [less ▲]

This paper describes a novel method to analyze the effect of the fiber laser induced plasma on welding of dissimilar Al and Cu. Based on spectroscopic studies, specific wavelengths were found to be suitable for process monitoring during laser welding. For aluminum, the double peak at 394.4 and 396.1 nm was studied, for cu the 578 nm peak was studied. The characteristic peaks were observed by multiple photodiodes equipped with narrow optical filters with varying FWHM. Analyzing the plasma emissions of the process enabled to detect material changes in the plasma plume. This novel method has the advantage of higher sampling rate combined with reduced costs compared to a spectrometer and is thus able to capture the process dynamics. [less ▲]

A key factor contributing to the non-realization of energy efficiency potentials is the routinized way in which many energy consumption behaviors (ECBs) are performed. To analyze routinized ECBs, we draw on social practice theory and psychological concepts and suggest a framework that considers individual, social, and material factors. Based on our proposed framework and employing multivariate regression analysis, we gain new insights into associated factors of routinized ECBs—particularly for washing and drying clothes and showering. Analyzing data from a survey conducted among Swiss households in 2016 (n=5015), we find that individual values, practice-specific wants, and materials explain variations in routinized ECB performance. Furthermore, socio-demographic predictors shed light on cultural and status differences associated with routinized ECBs. This paper contributes to understanding associated factors of routinized ECBs by bridging practice theory and psychology-based factors. [less ▲]

This article suggests a new approach towards online service provider liability which relies on duty of care. It proposes a concrete compliance framework for online platforms, borrowed from risk regulation, and modelled on anti-money laundering (AML) obligations in the financial sector. First, the prohibition on obliging platforms to monitor content in a general manner under the E-Commerce Directive will be discussed. On the face of it this may clash with a standardized requirement to filter for infringing content. Subsequently, the regulatory choice for such a duty of care standard will be explored. It is argued that the largely self-regulatory proposals currently on the table may be ill fitted to achieve traction and accountability. Finally, a three-tier compliance framework, modelled on the AML system and using a risk-based approach, is proposed. The pitfalls of such a highly automated compliance solution, which enforces complex legal norms, will also be touched on. [less ▲]

During the last decades of wind music research, a few publications focussed on terminology. Elmar Walter wrote a dissertation about Blas- und Bläsermusik. In his talk at Oberwölz, Raoul Camus stated: “A band is a Band is Band”. However, he seemed to hesitate because he referred to Joseph Manfredo who, in his awarded dissertation, asked: “What is a Band?” In my lecture, I will bring this topic to the fore again and deal with the terminology used to designate a group of wind instruments, and I will come up with some suggestions for definitions. I will try to find an answer to questions such as: When is a band a symphonic band, or even a symphonic wind ensemble or “only” a community band? When I say: “I will try to find an answer”, I must admit that I cannot guarantee to find an acceptable one: Are these terms filled with a substance – what makes the difference? – or are they simply a grandiloquent absurdity? Do pretentious terms refer to “better” musicians or music? I will present my paper in English, but I will also deal with band designations in German, in French and my native language – Luxembourgish.

Smart and optimal energy consumption in electric vehicles has high potential to improve the limited cruising range on a single battery charge. The proposed concept is a semi-autonomous ecological advanced driver assistance system which predictively plans for a safe and energy-efficient cruising velocity profile autonomously for battery electric vehicles. However, high entropy in transportation network leads to a challenging task to derive a computationally efficient and tractable model to predict the traffic flow. Stochastic optimal control has been developed to systematically find an optimal decision with the aim of performance improvement. However, most of the developed methods are not real-time algorithms. Moreover, they are mainly risk-neutral for safety-critical systems. This paper investigates on the real-time risk-sensitive nonlinear optimal control design subject to safety and ecological constraints. This system improves the efficiency of the transportation network at the microscopic level. Obtained results demonstrate the effectiveness of the proposed method in terms of states regulation and constraints satisfaction. [less ▲]

Former global inequality models lack realistic features of the population (age, gender, education, behavior). Worldsim develops a panel sample based simulation of the world population until 2050, relying on UN, Cepii, etc, big data aggregated forecasts, that we individually disaggregate. The simulation confirms the decline of the world's Gini index, but underlines several paradoxes in the socioecodemography of the world, with increasing gaps between resources and needs. Compared to more standard socioeconomic simulations of inequalities, we provide more substantial characterization of the population, and compared to other global simulations, we capture the dimensions of social divergences between social groups and geographic regions.

Workplace bullying is a serious phenomenon that has serious detrimental effects on victim’s health, attitudes, and work-related behavior. However, research that examines the mechanisms behind these relations is still sparse. Two theories that may explain the links between workplace bullying and various negative outcomes are social exchange theory and self-determination theory. Drawing on these theories, we hypothesized that the relationship between workplace bullying and various outcomes is mediated by perceptions of psychological contract violation and the frustration of basic psychological needs (i.e. autonomy, competence, relatedness). Therefore, the aim of our study was to test these mediators separately and simultaneously to see whether they have an incremental mediation effect between workplace bullying and well-being, work satisfaction, engagement, performance, burnout, workplace deviance and turnover intentions. An online survey design was employed and data were collected among U.S. employees. The final sample consists of 1,408 respondents (56.6% females, n=798, age: M=37.3, SD =10.4). Single mediation analysis within a structural equation modeling framework revealed that psychological contract violation acted as a mediator for all outcome variables. Furthermore, basic need frustrations were also meaningfully mediators between workplace bullying and all outcomes, but different need frustration were differently linked with them. The multiple mediation analyses mainly supported the hypothesized importance of the mediators for the different outcomes. The study findings advance the field through identifying the most important mediators between workplace bullying and several outcome variables guiding possible interventions. [less ▲]

The blast furnace iron making is the oldest but still the main method to produce liquid iron through sequential reduction processes of iron ore materials. Despite the existence of several discrete and continuous numerical models, there is no global method to provide detailed information about the processes inside the furnaces. The extended discrete element method known as XDEM is an advance numerical tool based on Eulerian – Lagrangian framework which is able to cover more information about the blast furnace process. Within this plat- form, the continuous phases such as gas and liquid phases are coupled to the discrete entities such as coke and iron ore particles through mass, momentum and energy exchange. This method has been applied to the shaft, cohesive zone, dripping zone and hearth of the blast furnace. In this chapter, the mathematical and numerical methods implemented in the XDEM method are described, and the results are discussed. [less ▲]
