- News and information spread over social media can have big impact on thoughts, beliefs, and opinions. It is therefore important to understand the sharing dynamics on these forums. However, most studies trying to capture these dynamics rely only on Twitters open APIs to measure how frequently articles are shared/retweeted, and therefore do not capture how many users actually read the articles linked in these tweets. To address this problem, in this paper, we first develop a novel measurement methodology, which combines the Twitter steaming API, the Bitly API, and careful sample rate selection to simultaneously collect and analyze the timeline of both the number of retweets and clicks generated by news article links. Second, we present a temporal analysis of the news cycle based on five-day-long traces (containing both clicks and retweet over time) for the news article links discovered during a seven-day period. Among other things, our analysis highlights differences in the relative timelines observed for clicks and retweets (e.g., retweet data often lags and underestimates the bias towards reading popular links/articles), and helps answer important questions regarding differences in how age-based biases and churn affect how frequently news articles shared on Twitter are accessed over time.

- To better determine the history of modern birds, we performed a genome-scale phylogenetic analysis of 48 species representing all orders of Neoaves using phylogenomic methods created to handle genome-scale data. We recovered a highly resolved tree that confirms previously controversial sister or close relationships. We identified the first divergence in Neoaves, two groups we named Passerea and Columbea, representing independent lineages of diverse and convergently evolved land and water bird species. Among Passerea, we infer the common ancestor of core landbirds to have been an apex predator and confirm independent gains of vocal learning. Among Columbea, we identify pigeons and flamingoes as belonging to sister clades. Even with whole genomes, some of the earliest branches in Neoaves proved challenging to resolve, which was best explained by massive protein-coding sequence convergence and high levels of incomplete lineage sorting that occurred during a rapid radiation after the Cretaceous-Paleogene mass extinction event about 66 million years ago.

- Purpose: Patient participation in goal setting and decision making is a core component of the rehabilitation process, but there is little information on what patients want to achieve after allogeneic stem cell transplantation (allo-SCT). The aim of this study was to describe adult patients' perceptions of goals related to health and function, as well as self-perceived limitations and facilitating strategies in the first 13 months after allo-SCT. Methods: Fifteen patients with a median age of 44 years (range, 22-65 years) were interviewed on one occasion during the first year after allo-SCT. Data were analysed using qualitative content analysis. Results: Results showed that patients felt that time after allo-SCT largely concerned: "to be healthy" and "to participate in a normal life". Some patients felt it was easy to set goals while others found it difficult. Most described goals had a long-term character. Patients were faced with a wide variety of limitations of which a few did not link to a described goal. Several facilitating strategies were described that either had or could help patients to reach their goals. Conclusions: Our results indicate that assistance with setting achievable goals, including individualised strategies and support from health care professionals to realise the goals, may assist in the rehabilitation to restore health and function after allo-SCT.

Creative Mathematical Reasoning : Does Need for Cognition Matter?
- 2022

Ingår i: Frontiers in Psychology. - : Frontiers Media S.A.. - 1664-1078. ; 12

Tidskriftsartikel (refereegranskat)abstract
- A large portion of mathematics education centers heavily around imitative reasoning and rote learning, raising concerns about students’ lack of deeper and conceptual understanding of mathematics. To address these concerns, there has been a growing focus on students learning and teachers teaching methods that aim to enhance conceptual understanding and problem-solving skills. One suggestion is allowing students to construct their own solution methods using creative mathematical reasoning (CMR), a method that in previous studies has been contrasted against algorithmic reasoning (AR) with positive effects on test tasks. Although previous studies have evaluated the effects of CMR, they have ignored if and to what extent intrinsic cognitive motivation play a role. This study investigated the effects of intrinsic cognitive motivation to engage in cognitive strenuous mathematical tasks, operationalized through Need for Cognition (NFC), and working memory capacity (WMC). Two independent groups, consisting of upper secondary students (N = 137, mean age 17.13, SD = 0.62, 63 boys and 74 girls), practiced non-routine mathematical problem solving with CMR and AR tasks and were tested 1 week later. An initial t-test confirmed that the CMR group outperformed the AR group. Structural equation modeling revealed that NFC was a significant predictor of math performance for the CMR group but not for the AR group. The results also showed that WMC was a strong predictor of math performance independent of group. These results are discussed in terms of allowing for time and opportunities for struggle with constructing own solution methods using CMR, thereby enhancing students conceptual understanding.

- PurposeThe purpose of this paper is to develop a deeper understanding of the organization-trainee relationship through a psychological contract lens, by exploring the psychological contract between the trainee and organization during and after the program and what factors may account for contract reciprocity.Design/methodology/approachInductive qualitative study design.FindingsData suggested that factors accounting for contract reciprocity during the program included: trainees’ responsibilities, trainees’ personal and professional development, trainees’ commitment, trainees’ delivery, and managerial and supervisory support. Factors identified accounting for contract reciprocity after individuals completed the program were: career opportunities, future-oriented dialogue between former trainees and managers, wage-setting, job tasks, and working conditions.Originality/valueThis exploratory research is original in that it identifies different factors accounting for the reciprocity during and after the program, and how this may be particularly relevant when talents are recruited externally to specifically participate in the program.

Diagnosis-specific disability pension predicts suicidal behaviour and mortality in young adults : a nationwide prospective cohort study
- 2013
-
Ingår i: BMJ Open. - : BMJ. - 2044-6055. ; 3:2

Tidskriftsartikel (refereegranskat)abstract
- Objectives: Increasing rates of disability pension (DP), particularly owing to mental diagnoses, have been observed among young adults in Organisation for Economic Co-operation and Development (OECD) countries. There is a lack of knowledge about the health prognosis in this group. The aim of this study was to investigate whether DP in young adulthood owing to specific mental diagnoses or somatic diagnoses predicts suicidal behaviour and all-cause mortality.Design: A nationwide prospective cohort study.Setting: A register study of all young adults who in 2005 were 19-23 years old and lived in Sweden. Registers held by the National Board of Health and Welfare, Statistics Sweden and the National Social Insurance Agency were used.Participants: 525 276 young adults. Those who in 2005 had DP with mental diagnoses (n=8070) or somatic diagnoses (n=3975) were compared to all the other young adults in the same age group (n=513 231).Outcome measures: HRs for suicide attempt, suicide and all-cause mortality in 2006-2010 were calculated by Cox proportionate hazard regression models, adjusted for sex, country of birth, parental education and parental and previous own suicidal behaviour.Results: The adjusted HR for suicide attempt was 3.32 (95% CI 2.98 to 3.69) among those on DP with mental diagnoses and 1.78 (95% CI 1.41 to 2.26) among those on DP with somatic diagnoses. For the specific mental diagnoses, the unadjusted HRs ranged between 2.42 (mental retardation) and 22.94 (personality disorders), while the adjusted HRs ranged between 2.03 (mental retardation) and 6.00 (bipolar disorder). There was an increased risk of mortality for young adults on DP in general, but only those with mental DP diagnoses had a significantly elevated HR of completed suicide with an adjusted HR of 3.92 (95% CI 2.83 to 5.43).Conclusions: Young adults on DP are at increased risk of suicidal behaviour and preterm death, which emphasises the need for improved treatment and follow-up.

- OBJECTIVE: Increasing rates of disability pension (DP) have been observed among young adults. We studied specific psychiatric DP diagnoses and subsequent risk of suicidal behaviour in a series of three cohorts of young adult in Sweden.METHOD: In a nationwide register study, we included all young adults who in 1995, 2000, and 2005, respectively, were 19-23 years old and lived in Sweden (n≈500,000 per cohort). Rates of DP and specific psychiatric DP diagnoses were recorded in each cohort. Hazard ratios (HRs) and 95% confidence intervals (CIs) for suicidal behaviour during the following five years, with the corresponding age group as reference, were calculated by Cox proportional hazard regression, adjusted for demographic variables and previous own and parental suicidal behaviour.RESULTS: The overall proportion with DP in this age group increased from 0.92% in 1995 to 2.29% in 2005, with particularly large increases in psychiatric diagnoses such as hyperkinetic disorders, pervasive developmental disorders, and depression/anxiety. The overall proportion of young disability pensioners attempting suicide during the five-year follow-up increased from 2.21% in the 1995 cohort to 3.81% in the 2005 cohort. Within most psychiatric DP diagnoses, the risk of attempted suicide did not change significantly over time, whereas suicide attempts increased in the reference group. Accordingly, the HRs for suicide attempt decreased in some psychiatric DP diagnoses. The highest adjusted HRs were observed for depression/anxiety (16.41; CI: 9.06 to 29.74) and schizophrenia (9.37; 6.13 to 14.31) in the 1995 cohort. The rate of suicide among young disability pensioners during follow-up ranged from 0.19% in 1995 to 0.37% in 2005, mainly occurring in individuals with psychiatric diagnoses.CONCLUSION: Suicidal behaviour has become more prevalent among young disability pensioners, which co-occurred with an increased tendency to grant DP in psychiatric diagnoses with a known high risk of suicidal behaviour. Preventive measures are warranted.
