Assaults on belonging : how Dutch youth without âblue eyes, cheese, and clogsâ experience everyday racism in educational contexts
Minoritized studentsâ ethnic backgrounds and racial appearances influence their academic opportunities and belonging experiences, and limit their access to safe and equal learning environments. In the Netherlands, limited research has focused on minoritized studentsâ experiences. In this study, we drew upon a theoretical framework focused on Othering and belonging as well as macro-/micro- connections related to racism to investigate the contemporary educational experiences of students from nondominant backgrounds. Participants experienced everyday racism and Othering in the: continuous centering of Whiteness and marginalization of the non-White Other; persistent obstacles perpetuated by educators that prevented parental participation; and consistent underestimation of studentsâ abilities by teachers and peers. As a step toward more just schooling, participants suggest that educators become more aware of minoritized studentsâ backgrounds and create spaces of belonging

The impact of participation restrictions on everyday life in long-term colorectal cancer survivors in the EnCoRe study:A mixed-method study
Purpose: Knowledge about long-term colorectal cancer (CRC) or treatment related health and functioning problems and on its impact on participation of CRC survivors in domestic life and in society is limited. We aimed to explore the nature and impact of cancer (treatment) related participation restrictions on everyday life of long-term CRC survivors, their current satisfaction with participation, and associations of health and functioning problems with participation satisfaction, using the International Classification of Functioning, Disability and Health (ICF) to comprehensively study participation.Method: Mixed-method study in 2-10 years post-diagnosis stage I-III CRC survivors (n = 151) from the cross-sectional part of the EnCoRe study. Participation restrictions were explored by semi-structured interviews in a subsample reporting participation restrictions (n = 10). Role functioning (SF36-Health Survey), fatigue (Checklist Individual Strength), and peripheral neuropathy symptoms (EORTC QLQ-CIPN20) were assessed in all participants and associations with self-reported participation satisfaction were analyzed by multivariable logistic regression models.Results: 19% of CRC survivors reported dissatisfaction with participation. Participation restrictions were reported for interpersonal relationships, work/employment, and social/civic life. CRC survivors reporting better physical and emotional role functioning were significantly less likely to be dissatisfied with their participation, whereas survivors reporting higher levels of fatigue or more peripheral neuropathy symptoms were more likely to be dissatisfied with participation.Conclusions: Colorectal cancer (treatment) related health and functioning problems negatively impacts the ability of nearly 1 in 5 long-term CRC survivors to participate in everyday life situations and their satisfaction with participation. Follow-up care needs to be able to identify and address these problems.</p
L'-band AGPM vector vortex coronagraph's first light on LBTI/LMIRCam
We present the first observations obtained with the L'-band AGPM vortex
coronagraph recently installed on LBTI/LMIRCam. The AGPM (Annular Groove Phase
Mask) is a vector vortex coronagraph made from diamond subwavelength gratings.
It is designed to improve the sensitivity and dynamic range of high-resolution
imaging at very small inner working angles, down to 0.09 arcseconds in the case
of LBTI/LMIRCam in the L' band. During the first hours on sky, we observed the
young A5V star HR\,8799 with the goal to demonstrate the AGPM performance and
assess its relevance for the ongoing LBTI planet survey (LEECH). Preliminary
analyses of the data reveal the four known planets clearly at high SNR and
provide unprecedented sensitivity limits in the inner planetary system (down to
the diffraction limit of 0.09 arcseconds).Comment: 9 pages, 4 figures, SPIE proceeding
Augmented reality meeting table: a novel multi-user interface for architectural design
Immersive virtual environments have received widespread attention as providing possible replacements for the media and systems that designers traditionally use, as well as, more generally, in providing support for collaborative work. Relatively little attention has been given to date however to the problem of how to merge immersive virtual environments into real world work settings, and so to add to the media at the disposal of the designer and the design team, rather than to replace it. In this paper we report on a research project in which optical see-through augmented reality displays have been developed together with prototype decision support software for architectural and urban design. We suggest that a critical characteristic of multi user augmented reality is its ability to generate visualisations from a first person perspective in which the scale of rendition of the design model follows many of the conventions that designers are used to. Different scales of model appear to allow designers to focus on different aspects of the design under consideration. Augmenting the scene with simulations of pedestrian movement appears to assist both in scale recognition, and in moving from a first person to a third person understanding of the design.

Morphological evolution of pulsed laser deposited ZrO2 thin films
Morphological evolution of ZrO2 thin films deposited during pulsed laser deposition of Zr in O2
atmosphere has been experimentally studied at two different film deposition temperatures, 300 and
873 K. The roughness exponent, , the growth exponent, , the coarsening exponent, 1/z, and the
exponent defining the evolution of the characteristic wavelength of the surface, p, for depositions at
300 K amounted to = 1.00.1, = 0.40.1, 1/z= 0.340.03, and p= 0.490.03, whereas for
depositions carried out at 873 K amounted to = 0.30.3, = 0.40.2, and 1/z= 0.00.2.
Experimental error becomes important due to the flat morphology of the films inherent to the
deposition technique. The change in the surface topography with the film temperature has been
studied with the help of a simple Monte Carlo model which indicates the existence of two different
growth regimes: a shadowing dominated growth, occurring at low temperatures, characterized by
calculated values = 1.000.04, = 0.500.04, p= 0.460.01, and 1/z= 0.350.02 and a
diffusion dominated growth that takes place at high temperatures as well as at low deposition rates,
characterized by calculated values = 0.150.08, = 0.330.04, and 1/z= 0.330.07. The good
agreement obtained between the experimental and simulated parameters is discussed within the
frame of the general characteristics of the deposition method.Universidad Nacional AutĂłnoma de MĂ©xico-PAPIIT-IN107808Consejo Nacional de Ciencia y TecnologĂa de MĂ©xico-CONACyT-50203-FMinisterio de Ciencia, InnovaciĂłn y Universidades de España-MAT 2007-65764, PIE 200960I132 y CONSOLIDER INGENIO 2010-CSD2008-00023Junta de AndalucĂa-TEP2275 y P07-FQM-0329
Generalized nonreciprocity in an optomechanical circuit via synthetic magnetism and reservoir engineering
Synthetic magnetism has been used to control charge neutral excitations for
applications ranging from classical beam steering to quantum simulation. In
optomechanics, radiation-pressure-induced parametric coupling between optical
(photon) and mechanical (phonon) excitations may be used to break time-reversal
symmetry, providing the prerequisite for synthetic magnetism. Here we design
and fabricate a silicon optomechanical circuit with both optical and mechanical
connectivity between two optomechanical cavities. Driving the two cavities with
phase-correlated laser light results in a synthetic magnetic flux, which in
combination with dissipative coupling to the mechanical bath, leads to
nonreciprocal transport of photons with 35dB of isolation. Additionally,
optical pumping with blue-detuned light manifests as a particle non-conserving
interaction between photons and phonons, resulting in directional optical
amplification of 12dB in the isolator through direction. These results indicate
the feasibility of utilizing optomechanical circuits to create a more general
class of nonreciprocal optical devices, and further, to enable novel
topological phases for both light and sound on a microchip.Comment: 18 pages, 8 figures, 4 appendice
Interaction between dislocation and coherent twin boundary by quasicontinuum model
The interaction between lattice dislocations and Coherent Twin Boundary ÎŁ3{111} of copper has been studied using Quasi-Continuum method. The coherent twin boundary provides high barrier to slip transmission. The dislocation pile-up modifies the stress field at its intersection with the grain boundary. A different reaction process compared with the case of single dislocations is noticed. One observes the nucleation of a Lomer-type dislocation with Burgers vector of Âœ and its glide on the (100) cube plane in the adjacent grain. This phenomenon has been observed with Transmission Electron Microscopy at room temperature and in other Molecular Dynamics simulations. We also show a novel interaction mechanism between Lomer-type dislocation and Coherent Twin Boundary. This interaction process leaves a dislocation with a Burgers vector coincident with the complete lattice shift of the Coherent Twin Boundary. Quantitative estimation of critical stress for various transmission phenomena is performed by using irial stress. Such information can be used as input for Discrete Dislocation Dynamics model
