- We present measurements of Underlying Event observables in pp collisions at root s = 0 : 9 and 7 TeV. The analysis is performed as a function of the highest charged-particle transverse momentum p(T),L-T in the event. Different regions are defined with respect to the azimuthal direction of the leading (highest transverse momentum) track: Toward, Transverse and Away. The Toward and Away regions collect the fragmentation products of the hardest partonic interaction. The Transverse region is expected to be most sensitive to the Underlying Event activity. The study is performed with charged particles above three different p(T) thresholds: 0.15, 0.5 and 1.0 GeV/c. In the Transverse region we observe an increase in the multiplicity of a factor 2-3 between the lower and higher collision energies, depending on the track p(T) threshold considered. Data are compared to PYTHIA 6.4, PYTHIA 8.1 and PHOJET. On average, all models considered underestimate the multiplicity and summed p(T) in the Transverse region by about 10-30%.

- The ALICE experiment at the LHC has studied J/psi production at mid-rapidity in pp collisions at root s = 7 TeV through its electron pair decay on a data sample corresponding to an integrated luminosity L-int = 5.6 nb(-1). The fraction of J/psi from the decay of long-lived beauty hadrons was determined for J/psi candidates with transverse momentum p(t) > 1,3 GeV/c and rapidity vertical bar y vertical bar < 0.9. The cross section for prompt J/psi mesons, i.e. directly produced J/psi and prompt decays of heavier charmonium states such as the psi(2S) and chi(c) resonances, is sigma(prompt J/psi) (p(t) > 1.3 GeV/c, vertical bar y vertical bar < 0.9) = 8.3 +/- 0.8(stat.) +/- 1.1 (syst.)(-1.4)(+1.5) (syst. pol.) mu b. The cross section for the production of b-hadrons decaying to J/psi with p(t) > 1.3 GeV/c and vertical bar y vertical bar < 0.9 is a sigma(J/psi <- hB) (p(t) > 1.3 GeV/c, vertical bar y vertical bar < 0.9) = 1.46 +/- 0.38 (stat.)(-0.32)(+0.26) (syst.) mu b. The results are compared to QCD model predictions. The shape of the p(t) and y distributions of b-quarks predicted by perturbative QCD model calculations are used to extrapolate the measured cross section to derive the b (b) over bar pair total cross section and d sigma/dy at mid-rapidity.

Tidskriftsartikel (refereegranskat)abstract
- Angular correlations between charged trigger and associated particles are measured by the ALICE detector in p-Pb collisions at a nucleon-nucleon centre-of-mass energy of 5.02 TeV for transverse momentum ranges within 0.5 < P-T,P-assoc < P-T,P-trig < 4 GeV/c. The correlations are measured over two units of pseudorapidity and full azimuthal angle in different intervals of event multiplicity, and expressed as associated yield per trigger particle. Two long-range ridge-like structures, one on the near side and one on the away side, are observed when the per-trigger yield obtained in low-multiplicity events is subtracted from the one in high-multiplicity events. The excess on the near-side is qualitatively similar to that recently reported by the CMS Collaboration, while the excess on the away-side is reported for the first time. The two-ridge structure projected onto azimuthal angle is quantified with the second and third Fourier coefficients as well as by near-side and away-side yields and widths. The yields on the near side and on the away side are equal within the uncertainties for all studied event multiplicity and p(T) bins, and the widths show no significant evolution with event multiplicity or p(T). These findings suggest that the near-side ridge is accompanied by an essentially identical away-side ridge. (c) 2013 CERN. Published by Elsevier B.V. All rights reserved.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: In 2015, 162,877 persons sought asylum in Sweden, 35,369 of whom were unaccompanied refugee minors (URMs). Refugee children, especially URMs, have often experienced traumas and are at significant risk of developing mental health problems, such as symptoms of post-traumatic stress disorder (PTSD), depression and anxiety, which can continue years after resettlement. The Swedish UnaccomPanied yOuth Refugee Trial (SUPpORT) aims to evaluate a community-based intervention, called Teaching Recovery Techniques (TRT), for refugee youth experiencing PTSD symptoms.METHODS/DESIGN: A randomised controlled trial will be conducted in which participants will be randomly allocated to one of two possible arms: the intervention arm (n = 109) will be offered the TRT programme, and the waitlist-control arm (n = 109) will receive services as usual, followed by the TRT programme around 20 weeks later. Outcome data will be collected at three points: pre-intervention (T1), post-intervention (T2; about 8 weeks after randomisation) and follow-up (T3; about 20 weeks after randomisation).DISCUSSION: This study will provide knowledge about the effect and efficiency of a group intervention for URMs reporting symptoms of PTSD in Sweden. TRIAL REGISTRATION: ISRCTN, ISRCTN47820795. Prospectively registered on 20 December 2018.

Are We Ready to Really Hear the Voices of Those Concerned? : Lessons Learned from Listening to and Involving Children in Child and Family Psychology Research

- A changing view of children, accelerated by the Convention of the Rights of the Child (UN in Convention on the rights of the child, UN Doc. A/RES/44/25, 1989, http://www2.ohchr.org/english/law/pdf/crc.pdf) has shifted the landscape of child and family research over the last few decades. Once viewed with low credibility and operating outside the interpretive framework of adult researchers, the rights-bearing child is increasingly recognized not only as having the capacity but also the right to participate in research. More recently, this movement has transitioned from the direct engagement of children as research participants—now considered commonplace, although less so for those who are structurally vulnerable—to the involvement of children in research design, review, conduct, and dissemination. Yet, both practical and ethical challenges remain. While children have the right to participation, they also have the right to protection. In this commentary, we set out to: (i) lay forth epistemic, child rights, and child sociology arguments for doing research about, with and by children and youth; (ii) recount our own journey of including children and youth in research to demonstrate the unique knowledge and insights gained through these approaches; and (iii) offer lessons learned on how to engage children and youth in research, including the involvement of structurally vulnerable groups.

- IntroductionMany researchers want to include seldom involved groups, such as refugees and youth, in patient and public involvement (PPI), but experience a number of barriers. The PPI research community calls for critical evaluations that are prospective, data-based and conducted by researchers and public contributors together. In this study, we conducted a longitudinal evaluation of a core activity in all collaborations: communication strategies. The aim was to evaluate the communication strategies adopted throughout a research project with refugee youth coresearchers.MethodsThis article is based on the evaluation of a project where refugee youth were involved in the online adaptation of a group-based programme for youth with posttraumatic stress. Behavioural observations and field notes collected during the project were analysed with qualitative content analysis and a readability index, and discussed through the lens of epistemic injustice. The article was cowritten by researchers and refugee youth.FindingsFour manifest categories were identified: Facilitating engagement through coplanning and circumstantial flexibility; Different needs require different channels; It's not just about the channel—facilitation skills matter; Finding a common language opens a communicative flow. In addition, a latent underlying theme reflecting the role of trust was identified: Interactive moments facilitate trust—trust facilitates richer involvement.ConclusionAt the core of the identified communication strategies were strengthening relationship-building and actively facilitating involvement. Establishing trusting relationships enabled refugee youth to share input. The communication strategies increased hermeneutical justice by contributing to a common understanding; thus, taking a step towards ameliorating epistemic injustice.

Tidskriftsartikel (refereegranskat)abstract
- Background: The prevalence of mental health problems is high among refugee children. Childhood mental health problems have long-term negative consequences and costs both for the individual child and society. The present study aimed to explore refugee parents’ experiences of their children’s mental health.Methodology: A qualitative explorative study was conducted. Data were collected through semistructured interviews with nine refugee mothers who have been in Sweden less than 5 years and with at least one child in the ages 8–14 years. Data were analyzed inductively using thematic network analysis.Results: The global theme that emerged from the analysis was Navigating the moving landscape of forced migration, which described the refugee mothers’ experiences of the previous adversity the family went through, the ongoing transition in the new context, and, lastly, the pathways to promote their children’s mental health. Two organizing themes described mothers’ and children’s navigation of the forced migration: Previous adverse events and new suffering and Promoting children’s well-being. Mothers described aggression and frequent conflicts, or refusal to play or eat, in their children related to living conditions at asylum centres and social isolation. This improved when children started school and possibilities of social relations increased. Mothers’ own mental health and lack of language skills could also have a negative impact on the children. To focus on the present and have hope of the future was helpful to the children. Encouragement and social support from parents, teachers, and friends promoted children’s well-being.Conclusion: The role of the host country in the promotion of the mental health of refugee children is emphasized. Interventions aimed to improve peer relations and reduce discrimination are needed, and these point to the school as a potential arena for positive change. Parental support groups were also mentioned as helpful in understanding the children’s need for support.

- Objective: Sweden is an international exception in its public health response to the COVID-19 pandemic, with a higher number of deaths, albeit not pediatric, compared with other Nordic countries. The objective of this study was to investigate what worries children and adolescents living in Sweden expressed in relation to the pandemic.Methods: Using an anonymous web-survey, 1,047 children (4–12 years; N = 717) and adolescents (13–18 years; N = 330) responded to five background and four open-ended questions, one of which was: Is there anything that you are worried about when it comes to ‘Corona’? The responses were coded using manifest content analysis. Interrater reliability was .95, assessed on the code level.Results: Worry was common (77%); mostly (60%) related to disease or death of elderly relatives, parents, the child him/herself or general worry for the elderly/risk groups. Existential worry (15%) comprised worries about the future, including economy and worries about the world perishing or the contagion becoming uncontrollable. A developmental trajectory was evident in the nature of responses. Adolescents’ worries about the future included missing out on their youth and employment. They also worried about society (6%), for example, the future of democracy and the world economy. There was no indication of socioeconomic status or geographic area (urban vs. rural) affecting the presence of worrisome thoughts.Conclusions: Worry about “Corona” was common. Universal preventative mental health intervention is warranted and could be conducted in the school setting. Intervention could be tailored by age, covering discussion on financial aspects with adolescents.
