- The aim of this study was to investigate the role of 70 Gy salvage radiotherapy (SRT) combined with short-term neoadjuvant hormonal therapy (NHT) in the treatment of recurrent disease after radical prostatectomy (RP), and to consider quality of life (QoL), survival outcomes and impact of co-morbidities on treatment-related rectal-genitourinary toxicity. Electronic records of 184 SRT patients treated consecutively between October 2001 and February 2007 were analyzed. Median age was 64 years (median follow-up 48 months). NHT was given to 165 patients (median 3 months). Pre-RP and pre-SRT PSA, PSA doubling time, Gleason score (GS), seminal vesicle invasion (SVI) and detectable post-SRT PSA were recorded. Any detectable PSA or PSA >0.1 ng/ml + nadir was considered biochemical failure (BcF). The Charlson co-morbidity index was used to correlate co-morbidities and rectal-genitourinary toxicity. Scores from the health-related QoL EORTC QLQ-C30 and PR-25 questionnaires were also evaluated. In 116 (63%) patients, a long-lasting curative effect was indicated by undetectable PSA levels. In univariate analysis, using BcF as an outcome variable, p<0.001 was found for GS, pre-SRT PSA, SVI and detectable post-SRT PSA. Multivariate analysis showed p=0.01 for SVI, p=0.09 for GS, and detectable post-SRT PSA (p=0.01); with metastases as an outcome variable, only SVI was significant (p=0.007). Cancer-specific and overall survival were 99 and 95%, respectively. Although microscopy showed SVI or GS 8-10 in the prostatectomy specimens 17/40 (43%) and 13/29 (45%), respectively, of patients still showed undetectable PSA at long-term follow-up (median 55 months) after SRT. Likewise, 11/31 (36%) patients with pre-SRT PSA >1.0 ng/ml and 80/134 (60%) patients with PSA doubling time (PSADT) <10 still showed undetectable PSA after 50 months. Slightly elevated acute and late rectal-genitourinary grade 3-4 toxicity was observed. No association with co-morbidity/toxicity was found. EORTC QLQ-C30 scores were similar to or slightly better than reference values. SRT with 70 Gy combined with 3-month NHT results in long-term undetectable PSA in >50% of patients with recurrence after RP with acceptable rectal-genitourinary toxicity and without negatively affecting long-term QoL. Non-metastatic patients should not be disqualified from receiving SRT although presenting with poor prognostic factors at surgery.

Hope and athlete burnout : Stress and affect as mediators

- ObjectiveIn this study we examined the relationship between trait hope and burnout in elite junior soccer players and whether stress and positive and negative affect mediated this relationship.MethodsParticipants were 238 Swedish soccer players (166 males, 71 females; one did not indicate gender) aged 15–19 years who completed questionnaires measuring trait hope, perceived stress, positive and negative affect, and athlete burnout (i.e., emotional/physical exhaustion, a reduced sense of accomplishment, and sport devaluation).ResultsBivariate correlations were consistent with hope theory contentions indicating significant negative relationships between hope and all three burnout dimensions. The relationship between hope and emotional/physical exhaustion was fully mediated by stress and positive affect. For sport devaluation and reduced sense of accomplishment, stress and positive affect partially mediated the relationship with hope. In contrast, negative affect did not mediate the relationship between hope and any of the burnout dimensions.ConclusionThe results support earlier findings that hope is negatively related to athlete burnout. Support was also found for the hypothesis that high hope individuals would experience less stress and therefore less burnout. Promoting hope may be relevant in reducing the likelihood of this detrimental syndrome.

Critical Imaginaries and Reflections on Artificial Intelligence and Robots in Postdigital K-12 Education
- 2019
-
In: Postdigital Science and Education. - : Springer Science and Business Media LLC. - 2524-485X .- 2524-4868 .- 2662-5326. ; 1:2, s. 427-445

Journal article (peer-reviewed)abstract
- It is commonly suggested that emerging technologies will revolutionize education. In this paper, two such emerging technologies, artificial intelligence (AI) and educational robots (ER), are in focus. The aim of the paper is to explore how teachers, researchers and pedagogical developers critically imagine and reflect upon how AI and robots could be used in education. The empirical data were collected from discussion groups that were part of a symposium. For both AI and ERs, the need for more knowledge about these technologies, how they could preferably be used, and how the emergence of these technologies might affect the role of the teacher and the relationship between teachers and students, were outlined. Many participants saw more potential to use AI for individualization as compared with ERs. However, there were also more concerns, such as ethical issues and economic interests, when discussing AI. While the researchers/developers to a greater extent imagined ideal future technology-rich educational practices, the practitioners were more focused on imaginaries grounded in current practice.

Estimating effects of teacher characteristics on student achievement in reading and mathematics: evidence from Swedish census data
- 2023

Journal article (peer-reviewed)abstract
- There is consensus that, for student achievement, teachers matter. However, providing reliable research evidence for the effects of observable teacher characteristics, such as qualification measures, has been difficult. The current study uses panel data based on register information from teachers and students to estimate effects of teacher characteristics on student achievement in mathematics and Swedish in Grade 6. Applying fixed-effects regression to a large sample of schools, we observed significant positive effects of several teacher characteristics. Having a teaching license was found to be one of the most important qualification measures, but teachers’ level of experience was also important for student achievement. The effects of teacher qualifications were generally stronger for mathematics than for Swedish.
