- Threshold concepts can be used to both organize disciplinary knowledge and explain why students have difficulties at certain points in the curriculum. Threshold concepts transform a student's view of the discipline; before being learned, they can block a student's progress. In this paper, we propose that in computing, skills, in addition to concepts, can sometimes be thresholds. Some students report finding skills more difficult than concepts. We discuss some computing skills that may be thresholds and compare threshold skills and threshold concepts.

- Objective: To evaluate end-point acuity in goal-directed arm movements in subjects with chronic neck pain, while taking the trade-off between speed and accuracy into account, and to evaluate associations between reduced acuity and self-rated characteristics.Design: Single-blinded, controlled, comparative group study.Subjects: Forty-five subjects with chronic non-traumatic, non-specific neck pain (n = 24) and whiplash-associated disorders (n = 21). Healthy subjects served as controls (n = 22). The groups were age- and sex-matched.Methods: Subjects performed fast and accurate pointing movements to a visual target. Group differences in end-point variability, controlled for peak velocity, were evaluated. Associations between end-point variability and self-rated symptoms, functioning, self-efficacy and kinesiophobia were analysed.Results: End-point acuity, controlled for peak velocity, was reduced for both neck-pain groups. Similar spatial error patterns across all groups indicated no direction-specific reduction. For both neck-pain groups, associations were found between end-point acuity and neck movement deficits, physical functioning and, in whiplash, also balance and pain.Conclusion: Acuity of goal-directed arm movements can be reduced in chronic neck pain. Associations between acuity and self-rated characteristics support the clinical validity of the results and indicate that impaired neck function contributes to reduced end-point acuity. The results can be of importance for characterization and rehabilitation of neck disorders.

Tidskriftsartikel (refereegranskat)abstract
- Research question/issueThe paper examines private engagements related to environmental, social, and governance (ESG) incidents as a corporate governance mechanism used by Nordic institutional investors to influence MSCI World companies. The questions addressed are how an agent‐led collaborative engagement is carried out, what are the characteristics of the target companies selected, and if the successful engagements can improve ESG performance compared with pre‐engagement and incomplete cases.Research findings/insightsA unique data set of 355 private engagements of a professional agent on behalf of its Nordic clients is studied on environment, human and labor rights, and corruption risks between 2005 and 2013. An engagement process of the agent is described with focus on sequence and duration of actions of private engagement dialogues before filing a resolution. Successful private engagements, when target companies adopt the proposed ESG changes, are 27.6%. The incident‐driven private engagements target companies rated with high market values and ESG performance. ESG performance and transparency increase for succeeded engagements in the postengagement period and relative to incomplete engagements.Theoretical/academic implicationsThe paper provides empirical support for a social movement‐based influence of private engagements on target companies and adds to the broad‐scale empirical literature on investor activism. In the Nordic governance setting, an agent‐coordinated private engagement is seen as a social movement that supports targeting companies with a potential for change.Practical/policy implicationsInsights are offered to actors in the value chain in financial markets by demonstrating that successful ESG engagements have the potential to change portfolio company ESG practices.

Tidskriftsartikel (refereegranskat)abstract
- The aim of the study was to analyze the exposure effects of different types of noise measures carried out at preschools. The project was carried out as an intervention study. The investigation included 89 employees at 17 preschools in the northern part of Sweden. Individual noise recordings and recordings in dining rooms and play halls were made at two departments in each preschool. The adverse effects on the employees were analyzed with validated questionnaires and saliva cortisol samples. Evaluations were made before and 1 year after the first measurement. Between the two measurements, measures were taken to improve the sound environments at the preschools. The effects of the measures varied a lot, with respect to both the sound environments and health. Regarding acoustical measures, significant changes were seen for some of the variables analyzed. For most of the tested effects, the changes, however, were very small and non-significant. The effects of organizational measures on the objective and subjective noise values were in overall less pronounced. Acoustical measures improved the subjectively rated sound environment more than organizational measures. This may be due to the high work effort needed to implement organizational measures. Even though the sound level was not lower, the personnel experienced improvements of the sound environment.

- The aim of the study was to analyze the presence of stress-related health problems among preschool employees and the way in which these reactions are related to noise and other work parameters. The investigation included 101 employees at 17 preschools in Umea County, located in northern Sweden. Individual noise recordings and recordings in dining rooms and play halls were made at two departments from each preschool. The adverse effects on the employees were analyzed by use of different validated questionnaires and by saliva cortisol samples. Stress and energy output were pronounced among the employees, and about 30 of the staff experienced strong burnout syndromes. Mental recovery after work was low, indicated by remaining high levels of stress after work. The burnout symptoms were associated with reduced sleep quality and morning sleepiness. Cortisol levels supported the conclusion about pronounced daily stress levels of the preschool employees.

- Hearing impairments and tinnitus are being reported in an increasing extent from employees in the preschool. The investigation included 101 employees at 17 preschools in Umeå county, Sweden. Individual noise recordings and stationary recordings in dining rooms and play halls were conducted at two departments per preschool. The effects of noise exposures were carried out through audiometric screenings and by use of questionnaires. The average individual noise exposure was close to 71 dB(A), with individual differences but small differences between the preschools. The noise levels in the dining room and playing halls were about 64 dB(A), with small differences between the investigated types of rooms and preschools. The hearing loss of the employees was significantly higher for the frequencies tested when compared with an unexposed control group in Sweden. Symptoms of tinnitus were reported among about 31% of the employees. Annoyance was rated as somewhat to very annoying. The voices of the children were the most annoying noise source. The dB(A) level and fluctuation of the noise exposure were significantly correlated to the number of children per department. The preschool sound environment is complex and our findings indicate that the sound environment is hazardous regarding auditory disorders. The fluctuation of the noise is of special interest for further research.

Sensorimotor disturbances in chronic neck pain - range of motion, peak velocity, smoothness of movement, and repositioning acuity.
- 2008

- The purpose of this pilot study was to evaluate sensorimotor functions in patients with chronic neck pain with objective and quantitative methods. A group of 16 patients with chronic idiopathic neck pain of insidious onset or whiplash associated disorders (WAD) was compared to an equally sized group of healthy subjects. Kinematics were investigated during voluntary head rotations by measuring range of motion, variability of range of motion (ROM-Variability), peak velocity, and smoothness of movement (jerk index). Repositioning acuity after cervical rotations was evaluated by analysing constant and variable error (VE). In comparison to the healthy subjects, the patients showed significantly larger jerk index, ROM-Variability and VE. No statistically significant differences were found between insidious neck pain and WAD. It is concluded that jerky and irregular cervical movements and poor position sense acuity are characteristic sensorimotor symptoms in chronic neck pain. The observed individuality in sensorimotor disturbances emphasizes the importance of developing specific rehabilitation programs for specific dysfunctions, and of using objective and quantitative methods for evaluation of rehabilitation.

Stroke and acute myocardial infarction in the Swedish Sami population : incidence and mortality in relation to income and level of education
- 2008

Tidskriftsartikel (refereegranskat)abstract
- Background: Gender differences in cardiovascular diseases (CVD) among the Sami have been reported previously. The aim of the present study was to investigate the incidence of and mortality from stroke, subarachnoid haemorrhage (SAH), and acute myocardial infarction (AMI) in the Swedish Sami population between 1985 and 2002, and to analyse the potential impact of income and level of education on cardiovascular morbidity and mortality. Methods: A Sami cohort of 15,914 persons (4,465 reindeer herding and 11,449 non-herding Sami) were followed up from 1985 to 2002 with regard to incidence and mortality rates of AMI, stroke, and SAH. Incidence and mortality ratios were calculated using a demographically matched non-Sami control population (DMC) as the standard (71,550 persons). Results: There was no elevated risk of developing AMI among the Sami compared with the DMC. However, the mortality ratio of AMI was significantly higher for Sami women. Higher incidence rates of stroke and SAH for both Sami men and women was observed, but no differences in mortality rates. Apart from the reindeer-herding men who demonstrated lower levels of income and education, the income and education levels among Sami were similar to the DMC. Conclusions: High mortality rates from AMI rather than stroke explain the excess mortality for CVD previously shown among Sami women. The results suggest that the differences in incidence of stroke between herding and non-herding Sami men, and between Sami women and non-Sami women, are caused by behavioural and psychosocial risk factors rather than by traditional socioeconomic ones.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: The objective of this study was to describe self-care practice during radiotherapy for cancer and to identify potential differences between practitioners and non-practitioners of self-care regarding sociodemographic, clinical, functional, and quality-of-life-related characteristics.Methods: In this descriptive study, 439 patients (87% response rate) undergoing radiotherapy responded to a study questionnaire regarding self-care, sociodemographic, clinical (eg, experienced symptoms), functional, and quality-of-life-related characteristics.Results: Of the 439 patients, 189 (43%) practiced at least one self-care strategy, while 250 (57%) did not. In total, the patients described 332 self-care practices, resulting in 14 different categories of self-care strategies. The 5 most common indicators of practicing self-care were fatigue, general wellbeing, psychological symptoms, nausea, vomiting and improving physical condition. The 5 most common self-care strategies were physical activity, increased recovery, healthy eating, distraction, and skincare. Patients who were married, were older than 69, patients with less education than university education, patients undergoing a combination of internal and external radiotherapy, patients experiencing fewer than 8 symptoms, and better quality of life, practiced self-care to a lower extent than did other patients. Functional capacity did not differ between self-care practitioners and non-practitioners.Conclusion and Implications for Practice: Of the patients undergoing radiotherapy, slightly less than half practiced self-care during an ordinary week of radiotherapy. Because older and less-educated patients were less likely to practice self-care, cancer care practitioners should consider paying particular attention to helping such patients with their self-care practice.

Tidskriftsartikel (refereegranskat)abstract
- The present study aimed at comparing participants with and without self reported musculoskeletal pain in a normal population with regard to performance on a range of tests for episodic memory, semantic memory, and other cognitive functions and to see if expected differences interacted with age. The results showed that participants with pain performed worse on a range of tasks as compared to participants without pain, and that these differences occurred regardless of age. The most robust effects of pain were displayed on tests for vocabulary and construction ability as these were the only effects that remained significant after controlling for years of education and reported depression in separate analyses. When depression and education were controlled for in the same analysis, even these effects were eliminated, suggesting interplay between pain, depressive status, and educational level in the negative effects on cognitive functioning.
