Drawing on social cognition frameworks, we experimentally examined preservice teachers’ implicit attitudes toward students with special educational needs (SEN) from different ethnic backgrounds and preservice teachers’ explicit attitudes toward inclusive education. Preservice teachers (N = 46) completed an evaluative priming task and questionnaires. Results showed indifferent implicit attitudes toward students with SEN with immigrant backgrounds and positive implicit attitudes toward those without immigrant backgrounds. Furthermore, participants reported a high motivation to act without prejudice toward minorities but held less favorable explicit attitudes toward inclusion of students with SEN, especially students with behavioral problems. Differential patterns of implicit and explicit evaluations could bias teachers’ interactions with students. Findings are discussed with respect to implications for educational practice and research.

Press freedom varies substantially across countries. In a free environment, any news becomes immediately public knowledge through mediums including various electronic media and published materials. However, in an unfree environment, (economic) agents would have more discretionary power to disclose good news immediately, while hiding bad news or releasing bad news slowly. We argue that this discretion is affecting stock prices and stock markets in countries with a free press should be better processors of economic information. Using an equilibrium asset-pricing model in an economy under jump diffusion, we decompose the moments of the returns of international stock markets into a diffusive risk and jump risk part. Using stock market data for a balanced panel of 50 countries, our results suggest that in countries with a free press, the better processing of bad news leads to more frequent negative jumps in stock prices. As a result, stock markets in those countries are characterized by higher volatility, driven by the higher jump risk, and more negative return asymmetry. Results are robust to the inclusion of various controls for governance and other country- or market-specific characteristics. We interpret this as good stock market characteristics, because a free press improves welfare and increases economic growth. [less ▲]

The study of colloidal dispersions of nanoparticles in liquid crystals (LCs) is well known. In most of the works, the particles are mixed into the LC to form suspensions with well-dispersed particles. However, when nanoparticles are physically connected to form networks, the overall macroscopic properties of the ensemble are directly linked to the specific properties of the nanoparticles. Carbon nanotubes (CNTs) are excellent electrical conductors possessing extremely high aspect ratio, which results in a very low concentration threshold needed to obtain percolation. Therefore, they form conductive networks with extremely small amounts of CNTs. Another advantage of carbon nanotubes is their capability to transport large current densities without damage by electromigration, maintaining a stable resistance, and having scattering-less paths across several microns. Moreover, the electromechanical properties of CNTs make them an ideal candidate in pressure sensing technology. The doctoral thesis presented here describes two different approaches to integrate and utilise CNTs in an LC matrix. In the first case, we show that a variety of nanoparticles that are dispersed in LC can be attracted and assembled onto a LC defect line generated in a predetermined location, thereby creating a vertical interconnect of nanoparticles. The second consists of CNT sheets mechanically drawn from a CNT forest and an LC cell is then built on top, and the second consists of a template-based assembly of dispersed CNTs onto defect lines in LCs. In this case, we study the electrical and optical properties of CNT sheets in the presence and absence of liquid crystals based on their DC electrical characterization with distributed electrical contacts. Finally, we discuss how these two approaches can be used to successfully fabricate pressure-sensing devices. The pressure response in both these sensors is achieved based on the change in resistance of the CNTs, induced by the structural variations under the external applied pressure. Both the pressure sensors developed here are easy to fabricate, cost-effective, and recoverable owing to the elasticity and softness of the LC. [less ▲]

Binary mixtures of nanoparticles self-assemble in the confinement of evaporating oil droplets and form regular supraparticles. We demonstrate that moderate pressure differences on the order of 100 kPa change the particles’ self-assembly behavior. Crystalline superlattices, Janus particles, and core–shell particle arrangements form in the same dispersions when changing the working pressure or the surfactant that sets the Laplace pressure inside the droplets. Molecular dynamics simulations confirm that pressure-dependent interparticle potentials affect the self-assembly route of the confined particles. Optical spectrometry, small-angle X-ray scattering and electron microscopy are used to compare experiments and simulations and confirm that the onset of self-assembly depends on particle size and pressure. The overall formation mechanism reminds of the demixing of binary alloys with different phase diagrams. [less ▲]

While the ``hierarchy of science'' has been widely analysed, there is no corresponding study of the status of subfields within a given scientific field. We use bibliometric data to show that subfields of mathematics have a different ``standing'' within the mathematics community. Highly ranked departments tend to specialize in some subfields more than in others, and the same subfields are also over-represented in the most selective mathematics journals or among recipients of top prizes. Moreover this status of subfields evolves markedly over the period of observation (1984--2016), with some subfields gaining and others losing in standing. The status of subfields is related to different publishing habits, but some of those differences are opposite to those observed when considering the hierarchy of scientific fields. We examine possible explanations for the ``status'' of different subfields. Some natural explanations -- availability of funding, importance of applications -- do not appear to function, suggesting that factors internal to the discipline are at work. We propose a different type of explanation, based on a notion of ``focus'' of a subfield, that might or might not be specific to mathematics. [less ▲]

Critical sociolinguistics has demonstrated that the social construct of the “native speaker” has a strong impact on people’s lives, but research on “native speaker effects” in the workplace remains rare. This article examines such effects from the perspective of four “native English speaker” trainees on temporary contracts in a multilingual European Union institution in Luxembourg. Applying the framework of sociolinguistic stance to interview data and drawings, we examine how the participants position themselves towards the “native English speaker” construct at work, and how they think others position them. According to our participants, “native English speaker” positioning confers privilege but restricts opportunities, demonstrating that the interest of a multilingual organisation in using the “native English speaker” as a resource does not automatically provide a powerful position to “native English speaking” workers. Our results featuring trainees in precarious labour conditions raise broader issues regarding the precaritisation of language work in the EU. [less ▲]

Presynaptic cannabinoid (CB1R) and metabotropic glutamate receptors (mGluR2/3) regulate synaptic strength by inhibiting secretion. Here, we reveal a presynaptic inhibitory pathway activated by extracellular signal-regulated kinase (ERK) that mediatesCB1R- andmGluR2/3-induced secretion inhibition. This pathway is triggered by a variety of events, from foot shock-induced stress to intense neuronal activity, and induces phosphorylation of the presynaptic protein Munc18-1. Mimicking constitutive phosphorylation of Munc18-1 results in a drastic decrease in synaptic transmission.ERK-mediated phosphorylation of Munc18-1 ultimately leads to degradation by the ubiquitin-proteasome system. Conversely, preventingERK-dependent Munc18-1 phosphorylation increases synaptic strength.CB1R- andmGluR2/3-induced synaptic inhibition and depolarization-induced suppression of excitation (DSE) are reduced uponERK/MEKpathway inhibition and further reduced whenERK-dependent Munc18-1 phosphorylation is blocked. Thus,ERK-dependent Munc18-1 phosphorylation provides a major negative feedback loop to control synaptic strength upon activation of presynaptic receptors and during intense neuronal activity.

This paper shows how Prêt à Voter can be adjusted in order to provide everlasting privacy. This is achieved by adapting the ballot generation and anonymisation process, such that only unconditional hiding commitments and zero knowledge proofs are published for verification, thus ensuring privacy towards the public. This paper presents a security analysis carried out in a collaboration between computer scientists and legal researchers. On the technical side it is shown that the modified Prêt à Voter provides verifiability, robustness, and everlasting privacy towards the public. Everlasting privacy towards the authorities can be achieved by implementing several organisational measures. A legal evaluation of these measures demonstrates that the level of privacy achieved would be acceptable under German law. [less ▲]
