Which students skip school? A comparative study of sociodemographic factors and student absenteeism using PISA data.

This article explores which students-with regard to gender, socio-economic background and migration background-skip school in Germany, Japan, Sweden and the United Kingdom (UK) according to PISA data. Students who skip school are observed in many countries, but there is not much systematic research that studies this across countries. Comparable data is to a large extent missing. PISA data offers an opportunity to use comparable data. In PISA, students were asked in 2018, 2015 and 2012 whether they had skipped school a whole day in the last two weeks prior to their completion of the PISA student questionnaire. Patterns of how absence relates to sociodemographic factors vary in countries and school systems. In the comparison between the four countries the UK stands out as having a higher percentage of students who have reported that they have skipped school than in the other countries. This does not seem to be related to any specific group of students. Japan also stands out with a lower percentage of students who have reported that they have skipped school. According to PISA data, skipping school is more related to socio-economic background than any other of the variables studied. The socio-economic background seems to be related to skipping school in all three PISA studies in Sweden and the UK. Gender seems not to be an important factor in the four countries. In Sweden and Germany there is a lower percentage of non-immigrant students who report that they have skipped school than first-and second-generation immigrant students. In the UK the figures are more ambiguous. When the percentages of students skipping school are compared over time and in the countries, it is difficult to find any trends, but the data only covered three measurements during a period of six years, which may be too short a time span to see trends.

Swedish Pupils' Perspectives on Emergency Remote Teaching during COVID-19 - A Qualitative Study.

Due to the COVID-19 pandemic, schools in many countries were forced to stop face-to-face teaching and switch to emergency remote teaching (ERT). The aim of this study, based on semi-structured interviews with upper secondary-school pupils in Stockholm, was to explore how Swedish pupils perceive their ERT and to understand their preconditions for learning. We found variations among pupils with regard to how they perceived their new morning routine, the increased flexibility in structuring their day, the flexibility to choose their workplace at home, and the decreased control by their teachers. While some perceived the increased flexibility as challenging, others appraised it as a possibility to be more independent. With regard to their classmates, all participants perceived difficulties learning from each other in ERT. Identified difficulties involved comparing one's performance to that of classmates, having deep discussions, encouraging each other, and organizing themselves in a group. The results are discussed in relation to previous studies, and are interpreted through the lenses of the Designs for Learning Theory.

The effect of a national web course "Help-Brain-Heart" as a supplemental learning tool before CPR training: a cluster randomised trial.

BACKGROUND: The effectiveness of cardiopulmonary resuscitation (CPR) learning methods is unclear. Our aim was to evaluate whether a web course before CPR training, teaching the importance of recognition of symptoms of stroke and acute myocardial infarction (AMI) and a healthy lifestyle, could influence not only theoretical knowledge but also practical CPR skills or willingness to act in a cardiac arrest situation. METHODS: Classes with 13-year-old students were randomised to CPR training only (control) or a web course plus CPR training (intervention). Data were collected (practical test and a questionnaire) directly after training and at 6 months. CPR skills were evaluated using a modified Cardiff test (12-48 points). Knowledge on stroke symptoms (0-7 points), AMI symptoms (0-9 points) and lifestyle factors (0-6 points), and willingness to act were assessed by the questionnaire. The primary endpoint was CPR skills at 6 months. CPR skills directly after training, willingness to act and theoretical knowledge were secondary endpoints. Training and measurements were performed from December 2013 to October 2014. RESULTS: Four hundred and thirty-two students were included in the analysis of practical skills and self-reported confidence. The mean score for CPR skills was 34 points after training (control, standard deviation [SD] 4.4; intervention, SD 4.0; not significant [NS]); and 32 points at 6 months for controls (SD 3.9) and 33 points for intervention (SD 4.2; NS). At 6 months, 73% (control) versus 80% (intervention; P = 0.05) stated they would do compressions and ventilation if a friend had a cardiac arrest, whereas 31% versus 34% (NS) would perform both if the victim was a stranger. One thousand, two hundred and thirty-two students were included in the analysis of theoretical knowledge; the mean scores at 6 months for the control and intervention groups were 2.8 (SD 1.6) and 3.2 (SD 1.4) points (P < 0.001) for stroke symptoms, 2.6 (SD 2.0) and 2.9 (SD 1.9) points (P = 0.008) for AMI symptoms and 3.2 (SD 1.2) and 3.4 (SD 1.0) points (P < 0.001) for lifestyle factors, respectively. DISCUSSION: Use of online learning platforms is a fast growing technology that increases the flexibility of learning in terms of location, time and is available before and after practical training. CONCLUSIONS: A web course before CPR training did not influence practical CPR skills or willingness to act, but improved the students' theoretical knowledge of AMI, stroke and lifestyle factors.

Effect of two additional interventions, test and reflection, added to standard cardiopulmonary resuscitation training on seventh grade students' practical skills and willingness to act: a cluster randomised trial.

OBJECTIVES: The aim of this research is to investigate if two additional interventions, test and reflection, after standard cardiopulmonary resuscitation (CPR) training facilitate learning by comparing 13-year-old students' practical skills and willingness to act. SETTINGS: Seventh grade students in council schools of two municipalities in south-east Sweden. DESIGN: School classes were randomised to CPR training only (O), CPR training with a practical test including feedback (T) or CPR training with reflection and a practical test including feedback (RT). Measures of practical skills and willingness to act in a potential life-threatening situation were studied directly after training and at 6 months using a digital reporting system and a survey. A modified Cardiff test was used to register the practical skills, where scores in each of 12 items resulted in a total score of 12-48 points. The study was conducted in accordance with current European Resuscitation Council guidelines during December 2013 to October 2014. PARTICIPANTS: 29 classes for a total of 587 seventh grade students were included in the study. PRIMARY AND SECONDARY OUTCOME MEASURES: The total score of the modified Cardiff test at 6 months was the primary outcome. Secondary outcomes were the total score directly after training, the 12 individual items of the modified Cardiff test and willingness to act. RESULTS: At 6 months, the T and O groups scored 32 (3.9) and 30 (4.0) points, respectively (p<0.001), while the RT group scored 32 (4.2) points (not significant when compared with T). There were no significant differences in willingness to act between the groups after 6 months. CONCLUSIONS: A practical test including feedback directly after training improved the students' acquisition of practical CPR skills. Reflection did not increase further CPR skills. At 6-month follow-up, no intervention effect was found regarding willingness to make a life-saving effort.

Effect of mobile application-based versus DVD-based CPR training on students' practical CPR skills and willingness to act: a cluster randomised study.

OBJECTIVES: The aim was to compare students' practical cardiopulmonary resuscitation (CPR) skills and willingness to perform bystander CPR, after a 30 min mobile application (app)-based versus a 50 min DVD-based training. SETTINGS: Seventh grade students in two Swedish municipalities. DESIGN: A cluster randomised trial. The classes were randomised to receive app-based or DVD-based training. Willingness to act and practical CPR skills were assessed, directly after training and at 6 months, by using a questionnaire and a PC Skill Reporting System. Data on CPR skills were registered in a modified version of the Cardiff test, where scores were given in 12 different categories, adding up to a total score of 12-48 points. Training and measurements were performed from December 2013 to October 2014. PARTICIPANTS: 63 classes or 1232 seventh grade students (13-year-old) were included in the study. PRIMARY AND SECONDARY OUTCOME MEASURES: Primary end point was the total score of the modified Cardiff test. The individual variables of the test and self-reported willingness to make a life-saving intervention were secondary end points. RESULTS: The DVD-based group was superior to the app-based group in CPR skills; a total score of 36 (33-38) vs 33 (30-36) directly after training (p<0.001) and 33 (30-36) and 31 (28-34) at 6 months (p<0.001), respectively. At 6 months, the DVD group performed significantly better in 8 out of 12 CPR skill components. Both groups improved compression depth from baseline to follow-up. If a friend suffered cardiac arrest, 78% (DVD) versus 75% (app) would do compressions and ventilations, whereas only 31% (DVD) versus 32% (app) would perform standard CPR if the victim was a stranger. CONCLUSIONS: At 6 months follow-up, the 50 min DVD-based group showed superior CPR skills compared with the 30 min app-based group. The groups did not differ in regard to willingness to make a life-saving effort.

Engagement in New Dietary Habits-Obese Women's Experiences from Participating in a 2-Year Diet Intervention.

BACKGROUND: Dietary weight loss interventions most often result in weight loss, but weight maintenance on a long-term basis is the main problem in obesity treatment. There is a need for an increased understanding of the behaviour patterns involved in adopting a new dietary behavior and to maintain the behaviour over time. PURPOSE: The purpose of this paper is to explore overweight and obese middle-aged women's experiences of the dietary change processes when participating in a 2-year-long diet intervention. METHODS: Qualitative semi-structured interviews with 12 overweight and obese women (54-71 years) were made after their participation in a diet intervention programme. The programme was designed as a RCT study comparing a diet according to the Nordic nutrition recommendations (NNR diet) and a Palaeolithic diet (PD). Interviews were analysed according to Grounded Theory principles. RESULTS: A core category "Engagement phases in the process of a diet intervention" concluded the analysis. Four categories included the informants' experiences during different stages of the process of dietary change: "Honeymoon phase", "Everyday life phase", "It's up to you phase" and "Crossroads phase". The early part of the intervention period was called "Honeymoon phase" and was characterised by positive experiences, including perceived weight loss and extensive support. The next phases, the "Everyday life phase" and "It's up to you phase", contained the largest obstacles to change. The home environment appeared as a crucial factor, which could be decisive for maintenance of the new dietary habits or relapse into old habits in the last phase called "Crossroads phase". CONCLUSION: We identified various phases of engagement in the process of a long-term dietary intervention among middle-aged women. A clear personal goal and support from family and friends seem to be of major importance for long-term maintenance of new dietary habits. Gender relations within the household must be considered as a possible obstacle for women engaging in diet intervention.

Social competence and behaviour problems in burned children.

The aim of this study was to collect follow-up data on social competence and behavioural problems in a sample of Swedish burned children and to compare the results with normative data from a reference group of children comparable in age, socio-economic status and gender. Parents of 44 children (55% response rate) aged 7-12 years were asked to complete a questionnaire booklet including the Children's Behaviour Questionnaire (CBQ) and the Social Competence Inventory (SCI). Data from the children's teachers were also collected for 20 children using the same booklet. In addition, data on TBSA, localisation of injury, and other background factors were collected. Results showed that the burned children were rated by their parents as showing lesser degrees of social initiative and more externalising problems and concentration problems compared with the control group. Teachers rated the burn injured children as having less prosocial orientation, more externalising problems, and more concentration problems. No clear effects were found for gender and characteristics of the burn injury. Results on the Social Competence Inventory were associated with scores on the Children's Behaviour Questionnaire.The findings are consistent with previous research in that the differences found were relatively small. However, they do call for attention to the possible adverse effects of growing up with a burn injury, but also to the possible pre-morbid characteristics that may be related to the injury.

Cadmium, copper and zinc in tissues of deceased copper smelter workers.

Workers at a copper and lead smelter in northern Sweden have a multifactorial exposure to a number of heavy metals. The concentrations of cadmium, copper and zinc in liver, lung, kidney and brain tissues have been determined by atomic absorption spectrometry in 32 deceased long-term exposed male lead smelter workers, and compared with those of 10 male controls. Furthermore, copper and zinc levels in hair and nails were determined by energy-dispersive X-ray fluorescence. The highest cadmium concentrations among both workers and controls were observed in kidney, followed in order by liver, lung and brain. The levels in kidney, liver and lung were all significantly higher in the workers than in the controls (p < 0.03). Among the workers relatively strong positive correlations (p < 0.03) were observed between cadmium concentrations in liver and lung, liver and kidney, liver and brain, and lung and brain. In the exposed workers a positive correlation was observed between cadmium and zinc concentrations in the kidney (rs = 0.38; p = 0.034). This is probably mainly due to the protein metallothionein, which is stored in the kidney, binding equimolar amounts of these two metals. The highest concentrations of copper were found in hair and nails among both workers and controls, followed in order by liver, brain, kidney and lung. The tissue concentrations of copper in brain, lung and kidney were all significantly higher among the smelter workers than in the controls (p < 0.036). Copper levels in lung and age at time of death were positively correlated among the exposed workers (rs = 0.39; p = 0.029). In the same group, positive correlations between copper and zinc concentrations in kidney (rs = 0.45; p = 0.009) and nails (rs = 0.68; p < 0.001) were also observed, reflecting possible biological interactions between these two metals. Among both workers and controls, the highest zinc concentrations were found in hair, followed in order by nails, liver, kidney, brain and lung. Significantly higher tissue concentrations among the workers as compared with the reference group were noted in kidney, liver and brain (p < 0.033). Neither copper nor zinc concentrations in hair and nails seemed to provide a useful measure of the trace element status of the smelter workers.
