- 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.

- 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%.

Protecting, managing and bending boundaries: a biomedicalization perspective on Swedish youth clinics’ responses to mental (ill) health
- 2022

Tidskriftsartikel (refereegranskat)abstract
- Background: Sweden has provided around 300 youth clinics (YCs) to address the health needs of young people since the 1970s. During the last few years, and as part of an effort to strengthen mental healthcare for young people, YCs’ role in the provision of mental healthcare has been widely debated. With such debates as background, the aim of this study is to analyse Swedish YCs’ responses to the mental (ill) healthcare needs of young people, from the perspective of national level stakeholders.Methods: We used thematic analysis of interviews with eight national level stakeholders in the field of youth mental health in Sweden. Building upon the concept of biomedicalization we examined the discourses on mental (ill) health, healthcare and youth that such responses reproduce.Results: YCs engage in the three simultaneous, but at times contradictory, responses of protecting, managing and bending boundaries. Remaining true to their mission as a health-promotion service compels them to protect their boundaries and limit the type of mental health issues they address. However, the perceived malfunctioning of specialized services has led them to bend these boundaries to allow in more young people with severe mental health problems. Caught between protecting and bending boundaries, the response of managing boundaries to decide who should be allowed in and who should be sent elsewhere has emerged as a middle-way response. However, it is not free from conflicts.Conclusion: Building upon the concept of biomedicalization, this study poses two questions. The first relates to whether it is possible to support young people and their health without reinforcing discourses that represent young people as collectively at risk, and if so how this can be done. The second relates to the provision of mental healthcare for young people, and the need to identify conditions for integrating diagnosis and treatment within YCs, without hindering their holistic and youth-centred approach.

- Purpose: The aim of this study was to explore how health care providers at youth clinics (YCs) in Sweden engage with, focus on, and navigate across the mental health youth space, while upholding the core bedrock principle of "youth-centeredness".Methods: Qualitative interviews were conducted with 21 health care professionals working in three YCs located in three different regions of Sweden. Data were analysed using reflexive thematic analysis informed by the work of Braun and Clarke.Results: The three themes were: 1) "youth mission-at the core of the YCs" work and challenged by a stronger involvement in mental ill health'; 2) "YCs" unique and complementary role in the youth mental health system: a holistic perspective, team work, and a focus on normalization', and 3) "Caught between a rock and a hard place: to treat at a care level that is not optimal for the young users" needs or to refer within an unreliable system'.Conclusion: This study reflects the individuality and key features of YCs, their widening roles within the mental health sphere, and the challenges faced in maintaining and expanding the characteristic "youth-centred" approach while expanding their work with mental health

- In two studies, the role of nature experiences and social norms during childhood is explored next to adulthood biospheric values, connectedness to nature, environmental identity, and objective knowledge in relation to pro-environmental behaviors. Study 1 (N = 185) tested the hypothesized model in the realm of general pro-environmental behaviors and sustainable fruit consumption on a sample of students. Study 2 (N = 155) tested the model in the realm of sustainable seafood consumer choice on a general population sample. Path analyses show consistent results across samples. Results show that childhood nature experiences and exposure to pro-environmental social norms during childhood are related to adulthood development of connectedness with nature and biospheric values; these, in turn, help in shaping adulthood environmental self-identity ultimately influencing the enactment of sustainable food choices during adulthood. These findings point toward the relevance of childhood experiences for pro-environmental behaviors as compared to the provision of information. The role of objective knowledge across samples is inconsistent, thus requiring future investigations.

Exploring cross-boundary collaborationfor youth mental health in Sweden : a qualitative study using the integrativeframework for collaborative governance

Tidskriftsartikel (refereegranskat)abstract
- Background: Youth mental health is a major health concern in almost every country. Mental health accounts for about 13% of the global burden of disease in the 10-to-19-year age group. Still there are significant gaps between the mental health needs of young people and the quality and accessibility of available services. Collaboration between health and social service actors is a recognized way of reducing gaps in quality and access. Yet there is little scientific evidence on how these collaborations are applied, or on the challenges of cross-boundary collaboration in the youth mental health space. This study aims to explore how collaboration is understood and practiced by professionals working in the Swedish youth mental health system.Methods: We conducted 42 interviews (November 2020 to March 2022) with health and social care professionalsand managers in the youth mental health system in Sweden. Interviews explored participants’ experience andunderstanding of the purpose, realization, and challenges of collaboration. Data were analysed under an emergentstudy design using reflexive thematic analysis.Results: The analysis produced three themes. The first shows that collaboration is considered as essential andimportant, and that it serves diverse purposes and holds multiple meanings in relation to professionals’ roles andresponsibilities. The second addresses the different layers of collaboration, in relation to activities, relationships, andtarget levels, and the third captures the challenges and criticisms in collaborating across the youth mental healthlandscape, but also in growing possibilities for future development.Conclusion: We conclude that collaboration serves multiple purposes and takes many shapes in the Swedish youth mental health system. Despite the many challenges, participants saw potential in further building collaboration. Interestingly our participants also raised concerns about too much collaboration. There was scepticism about collaboration directing attention away from young people to the professionals, thereby risking the trust and confidentiality of their young clients. Collaboration is not a panacea and will not compensate for an under-resourced youth mental health system.

- Introduction: Strengthening first-line mental healthcare services for youth remains a priority for the Swedish government. The government is currently investigating how different sectors involved can be strengthened, butevidence is scarce. Youth clinics play a key role in these discussions, being one of the most trusted services for youth. However, analysis of organisational functions andcoordination with other services is important to strengthen youth clinics’ role in first-line mental healthcare. This study investigates these challenges and aims to analysethe integration of mental healthcare within youth clinics to identify strategies to strengthen first-line mental healthcare for youth in Sweden.Methods and analysis: This study adopts a health policyand systems approach. In the first phase, a formative realist evaluation is conducted to ascertain what works in terms of integrating mental healthcare services within youth clinics, for what type of youth subpopulations and under what circumstances. National-level stakeholders will be interviewed to elicit the programme theory that explains how the intervention is supposed to work. The programme theory will then be tested in three–five cases. The cases will be comprised of youth clinics and their stakeholders. Quantitative and qualitative information will be gathered,including via visual methodologies and questionnaires. The second phase includes a concept mapping study, engaging stakeholders and young people to build consensuson strategies to strengthen the integration of menta lhealthcare into youth clinics.
