- Pervading global narratives suggest that political polarization is increasing, yet the accuracy of such group meta-perceptions has been drawn into question. A recent US study suggests that these beliefs are inaccurate and drive polarized beliefs about out-groups. However, it also found that informing people of inaccuracies reduces those negative beliefs. In this work, we explore whether these results generalize to other countries. To achieve this, we replicate two of the original experiments with 10,207 participants across 26 countries. We focus on local group divisions, which we refer to as fault lines. We find broad generalizability for both inaccurate meta-perceptions and reduced negative motive attribution through a simple disclosure intervention. We conclude that inaccurate and negative group meta-perceptions are exhibited in myriad contexts and that informing individuals of their misperceptions can yield positive benefits for intergroup relations. Such generalizability highlights a robust phenomenon with implications for political discourse worldwide.

- Economic inequality is associated with preferences for smaller, immediate gains over larger, delayed ones. Such temporal discounting may feed into rising global inequality, yet it is unclear whether it is a function of choice preferences or norms, or rather the absence of sufficient resources for immediate needs. It is also not clear whether these reflect true differences in choice patterns between income groups. We tested temporal discounting and five intertemporal choice anomalies using local currencies and value standards in 61 countries (N = 13,629). Across a diverse sample, we found consistent, robust rates of choice anomalies. Lower-income groups were not significantly different, but economic inequality and broader financial circumstances were clearly correlated with population choice patterns. Ruggeri et al. find in a study of 61 countries that temporal discounting patterns are globally generalizable. Worse financial environments, greater inequality and high inflation are associated with extreme or inconsistent long-term decisions.

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
- 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
- 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%.

- Compared with reduced-intensity conditioning (RIC), myeloablative conditioning (MAC) is generally associated with lower relapse risk after allogeneic hematopoietic cell transplantation (HCT) for acute myelogenous leukemia (AML) and myelodysplastic syndromes (MDS). However, disease-specific risk factors in AML/MDS can further inform when MAC and RIC may yield differential outcomes. We analyzed HCT outcomes stratified by the Disease Risk Index (DRI) in 4387 adults (age 40 to 65 years) to identify the impact of conditioning intensity. In the low/ intermediate-risk DRI cohort, RIC was associated with lower nonrelapse mortality (NRM) (hazard ratio [HR],.74; 95% confidence interval [CI],.62 to.88; P <.001) but significantly greater relapse risk (HR, 1.54; 95% CI, 1.35 to 1.76; P <.001) and thus inferior disease-free survival (DFS) (HR, 1.19; 95% CI, 1.07 to 1.33; P =.001). In the high/ very high-risk DRI cohort, RIC was associated with marginally lower NRM (HR,.83; 95% CI,.68 to 1.00; P =.051) and significantly higher relapse risk (HR, 1.23; 95% CI, 1.08 to 1.41; P =.002), leading to similar DFS using either RIC or MAC. These data support MAC over RIC as the preferred conditioning intensity for patients with AML/MDS with low/intermediate-risk DRI, but with a similar benefit as RIC in high/very high-risk DRI. Novel MAC regimens with less toxicity could benefit all patients, but more potent antineoplastic approaches are needed for the high/ very-high risk DRI group.

Tidskriftsartikel (refereegranskat)abstract
- Internet-delivered interventions are generally effective for psychological problems. While the presence of a clinician guiding the client via text messages typically leads to better outcomes, the characteristics of what constitutes high-quality communication are less well investigated. This study aimed to identify how an internet therapist most effectively communicates with clients in internet-delivered cognitive behavioral therapy (ICBT). Using data from a treatment study of depressed adolescents with a focus on participants who had a positive outcome, messages from therapists were analyzed using thematic analysis. The study focused on the therapist's 1) encouragement and 2) affirmation, and how the therapists used 3) personal address. The analysis resulted in a total of twelve themes (Persistence Wins, You Are a Superhero, You Make Your Luck, You Understand, Hard Times, You Are Like Others, My View on the Matter, Time for a Change, Welcome In, Let Me Help You, You Affect Me, and I Am Human). Overall, the themes form patterns where treatment is described as hard work that requires a motivated client who is encouraged by the therapist. The findings are discussed based on the cognitive behavioral theoretical foundation of the treatment, prior research on therapist behaviors, and the fact that the treatment is provided over the internet.

- Magnetic nanoparticles (MNPs) are instrumental for fabrication of tailored nanomagnetic structures, especially where top-down lithographic patterning is not feasible. Here, we demonstrate precise and controllable manipulation of individual magnetite MNPs using the tip of an atomic force microscope. We verify our approach by placing a single MNP with a diameter of 50 nm on top of a 100 nm Hall bar fabricated in a quasi-two-dimensional electron gas (q2DEG) at the oxide interface between LaAlO3 and SrTiO3 (LAO/STO). A hysteresis loop due to the magnetic hysteresis properties of the magnetite MNPs was observed in the Hall resistance. Further, the effective coercivity of the Hall resistance hysteresis loop could be changed upon field cooling at different angles of the cooling field with respect to the measuring field. The effect is associated with the alignment of the MNP magnetic moment along the easy axis closest to the external field direction across the Verwey transition in magnetite. Our results can facilitate experimental realization of magnetic proximity devices using single MNPs and two-dimensional materials for spin-based nanoelectronics. © 2022 The Authors.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Background: Internet-based psychological treatments provide many benefits for patients with psychiatric disorders, but research also suggests that negative effects might occur from the interventions involved.Methods: A total of 2400 participants presenting with anxiety and/or depression were randomized into 12 subgroups (n=200 each) based on treatment modality (Cognitive Behavior Therapy vs. Psychodynamic Therapy vs. Waitlist), duration (8 vs. 16 weeks), and moderated discussion forum (Yes vs. No). In addition to weekly measurements of the primary outcome measure (PHQ-9 & GAD-7), the Negative Effects Questionnaire was administered post-treatment. The Negative Effects Questionnaire has been proposed as a valuable instrument for investigating the negative effects of psychological treatments. An exploratory factor analysis suggested a six-factor solution: symptoms (“I felt more worried”), quality (“I did not always understand my treatment”), dependency (“I think that I have developed a dependency on my treatment”), stigma (“I became afraid that other people would find out about my treatment”), hopelessness (“I started thinking that the issue I was seeking help for could not be made any better”), and failure (“I lost faith in myself”).Results: All 2400 participants have been recruited. However, all post-assessment data is not yet collected at the time of writing (but will be by the time of the conference). This talk will focus on the occurrence and characteristics of the potential negative effects of internet-based treatment in the 12 subgroups.Discussion: Negative effects of psychotherapy are multifaceted, warranting careful considerations for them to be monitored and reported in research settings and routine care.

Ingår i: Abstracts and Program Parallel Sessions. ; , s. 32-32
-
Konferensbidrag (refereegranskat)abstract
- Aim: The aim of the TRAbee study was to compare the effectiveness of two transdiagnostic treatment modalities, Unified Protocol (Cognitive Behavior Therapy) and Affect Phobia Therapy (Psychodynamic Psychotherapy), in alleviating psychological distress and to examine the relative differences in the incidence of negative effects as assessed by the Negative Effects Questionnaire.Methods: This study is a randomized controlled trial with 2,400 participants divided into 12 subgroups based on treatment modality (CBT vs. PDT vs. waitlist), duration (8 or 16 weeks of treatment), and discussion forum access (yes/no). Participants were randomly assigned and measured weekly during treatment, and then at 6, 12, and 24 months. Inclusion criteria were: age 18 years or older, ability to read/write Swedish, access to a smartphone/computer, GAD-7 score ≥5, and/or PHQ-9 score ≥10. Exclusion criteria included: current psychological treatment, recent medication change, severe depression/suicidality. Outcome measures included the Generalized Anxiety Disorder 7-item scale (GAD-7), the Patient Health Questionnaire 9-item scale (PHQ-9), the Personality Inventory for DSM-5 (PID-5), the Reflective Functioning Questionnaire 8-item scale (RFQ- 8), the Negative Effects Questionnaire (NEQ), and the Brunnsviken Brief Quality of Life scale (BBQ).Results: Follow-up data is still being collected, but preliminary results, including 12-month follow-up, will be available at the ISRII conference. The results will report on the relative differences in the incidence of negative effects between the treatments as assessed by the NEQ scale.Conclusions: The study will provide insights into the comparative effectiveness of Unified Protocol and Affect Phobia Therapy in addressing psychological disorders in a transdiagnostic manner, as well as shedding light on the differences in negative effects experienced by patients undergoing these treatments. This information may inform future treatment approaches and help to optimize patient outcomes.
