Abstract

Background: Refugee youth experience hardships associated with exposure to trauma in their homelands and during and after displacement, which results in higher rates of common mental disorders. The World Health Organization (WHO) developed Problem Management Plus (PM+), a non-specialist-delivered brief psychological intervention, for individuals who have faced adversity. PM+ comprises problem-solving, stress management, behavioural activation and strengthening social support. However, it does not include an emotional processing component, which is indicated in trauma-exposed populations. Objective: This pilot randomized controlled trial (RCT) aims to evaluate the feasibility and acceptability of PM+, adapted to Syrian, Eritrean and Iraqi refugee youth residing in the Netherlands, with and without a newly developed Emotional Processing (EP) Module. Methods: Refugee youth (N = 90) between 16 and 25 years of age will be randomized into PM+ with care-as-usual (CAU), (n = 30), PM+ with Emotional Processing (PM+EP) with CAU (n = 30) or CAU only (n = 30). Inclusion criteria are self-reported psychological distress (Kessler Psychological Distress Scale; K10 > 15) and impaired daily functioning (WHO Disability Assessment Schedule; WHODAS 2.0 > 16). Participants will be assessed at baseline, one-week post-intervention and three-month follow-up. The main outcome is the feasibility and acceptability of the adapted PM+ and PM+EP. The secondary outcomes are self-reported psychological distress, functional impairment, post-traumatic stress disorder (PTSD) symptom severity and diagnosis, social support, and self-identified problems. The pilot RCT will be succeeded by a process evaluation including trial participants, participants’ significant others, helpers, and mental health professionals (n = 20) to evaluate their experiences with the PM+ and PM+EP programmes. Results and Conclusion: This is the first study that evaluates the feasibility of PM+ for this age range with an emotional processing module integrated. The results may inform larger RCTs and implementation of PM+ interventions among refugee youth. Trial Registration: Registered to Dutch Trial Registry, NL8750, on 3 July 2020.

Abstract

Fluctuations in the intensity and polarization of the cosmic microwave background (CMB) and the large-scale distribution of matter in the universe each contain clues about the nature of the earliest moments of time. The next generation of CMB and large-scale structure (LSS) experiments are poised to test the leading paradigm for these earliest moments---the theory of cosmic inflation---and to detect the imprints of the inflationary epoch, thereby dramatically increasing our understanding of fundamental physics and the early universe. A future CMB experiment with sufficient angular resolution and frequency coverage that surveys at least 1 of the sky to a depth of 1 uK-arcmin can deliver a constraint on the tensor-to-scalar ratio that will either result in a 5-sigma measurement of the energy scale of inflation or rule out all large-field inflation models, even in the presence of foregrounds and the gravitational lensing B-mode signal. LSS experiments, particularly spectroscopic surveys such as the Dark Energy Spectroscopic Instrument, will complement the CMB effort by improving current constraints on running of the spectral index by up to a factor of four, improving constraints on curvature by a factor of ten, and providing non-Gaussianity constraints that are competitive with the current CMB bounds.

Abstract

We present a new compilation of Type Ia supernovae (SNe Ia), a new data set of low-redshift nearby-Hubble-flow SNe, and new analysis procedures to work with these heterogeneous compilations. This >Union> compilation of 414 SNe Ia, which reduces to 307 SNe after selection cuts, includes the recent large samples of SNe Ia from the Supernova Legacy Survey and ESSENCE Survey, the older data sets, as well as the recently extended data set of distant supernovae observed with the Hubble Space Telescope (HST). A single, consistent, and blind analysis procedure is used for all the various SN Ia subsamples, and a new procedure is implemented that consistently weights the heterogeneous data sets and rejects outliers. We present the latest results from this Union compilation and discuss the cosmological constraints from this new compilation and its combination with other cosmological measurements (CMB and BAO). The constraint we obtain from supernovae on the dark energy density is ¿¿ = 0.713+ 0.027¿0.029(stat)+ 0.036¿0.039(sys) , for a flat, ¿CDM universe. Assuming a constant equation of state parameter, w, the combined constraints from SNe, BAO, and CMB give w = ¿ 0.969+ 0.059¿0.063(stat)+ 0.063¿0.066(sys) . While our results are consistent with a cosmological constant, we obtain only relatively weak constraints on a w that varies with redshift. In particular, the current SN data do not yet significantly constrain w at z > 1. With the addition of our new nearby Hubble-flow SNe Ia, these resulting cosmological constraints are currently the tightest available.
