How teachers understand and strategize about emerging conflicts

This article concerns what have been variously called mild misbehaviours, minor distractions or emerging conflicts, i.e. situations of mild tension between the teacher and pupils in the classroom. The article responds to calls for further studies on the link between how teachers understand these emerging conflicts and the strategies they suggest to handle them. We carried out two studies on primary school teachers in Sweden, using a qualitatively driven mixed-method design, i.e. the studies were carried out sequentially using different qualitative methods. The first study, the main study, based on individual interviews with 20 teachers, used a phenomenographic approach, capturing these teachers’ different understandings of emerging conflict. The second study, the supplemental study, based on six group interviews with 18 teachers, built on the main study and used a hermeneutic approach, capturing how these teachers link a certain understanding of emerging conflicts to certain themes of suggested strategies. By utilizing this design, we were able to investigate the aforementioned link and build a model of nine different understandings, each linked to one to four strategy themes. Altogether, 22 different strategy themes, together encompassing a multitude of separate strategies, were recognized and linked to the nine different understandings. The results suggest that teachers have a more divergent and nuanced understanding of emerging conflicts, and how to handle them, than earlier studies of this link have reported. The results give valuable insights into developing more accurate quantitative surveys as well as more suitable teacher training programmes.     

Joint power generation differentiates young and adult sprinters during the transition from block start into acceleration: a cross-sectional study

The aim of this study was to investigate differences in joint power generation between well-trained adult athletes and young sprinters from block clearance to initial contact of second stance. Eleven under 16 (U16) and 18 under 18 (U18) promising sprinters executed an explosive start action. Fourteen well-trained adult sprinters completed the exact same protocol. All athletes were equipped with 74 spherical reflective markers, while an opto-electronic motion analysis system consisting of 12 infrared cameras (250 Hz, MX3, Vicon, Oxford Metrics, UK) and 2 Kistler force plates (1,000 Hz) was used to collect the three-dimensional marker trajectories and ground reaction forces (Nexus, Vicon). Three-dimensional kinematics, kinetics, and power were calculated (Opensim) and time normalised from the first action after gunshot until initial contact of second stance after block clearance. This study showed that adult athletes rely on higher knee power generation during the first stance to induce longer step length and therefore higher velocity. In younger athletes, power generation of hip was more dominant.     

The effect of rowing headgear on forced convective heat loss and radiant heat gain on a thermal manikin headform

Both radiant and forced convective heat flow were measured for a prototype rowing headgear and white and black cotton caps. The measurements were performed on a thermal manikin headform at a wind speed of 4.0 m . s(-1) (s = 0.1) in a climate chamber at 22.0 degrees C (s = 0.05), with and without radiant heat flow from a heat lamp, coming from either directly above (90 degrees ) or from above at an angle of 55 degrees . The effects of hair were studied by repeating selected measurements with a wig. All headgear reduced the radiant heat gain compared with the nude headform: about 80% for the caps and 95% for the prototype rowing headgear (P < 0.01). Forced convective heat loss was reduced more by the caps (36%) than by the prototype rowing headgear (9%) (P < 0.01). The radiant heat gain contributed maximally 13% to the net heat transfer, with or without headgear, showing that forced convective heat loss is the dominant heat transfer parameter under the chosen conditions. The results of the headgear - wig combinations were qualitatively similar, with lower absolute heat transfer.     

The use of accelerometry in adolescents and its implementation with non-wear time activity diaries in free-living conditions

The aim of this study was to evaluate the use of a non-wearing time activity diary (hereafter non-wear activity diary) when using accelerometry in adolescents to provide insight into their physical activity levels. In total, 213 Belgian adolescents (89 boys, 124 girls) were eligible for this study. Adolescents wore an accelerometer for seven consecutive days and kept a non-wear activity diary. On the last day, they completed the International Physical Activity Questionnaire for Adolescents. The differences between the accelerometer data with and without use of the non-wear activity diary were significant for all physical activity intensities according to the Wilcoxon signed rank test. Bland-Altman plots showed that with more time spent in any physical activity intensity, the difference between including and not including the non-wear activity diary increased. The correlation coefficient between the International Physical Activity Questionnaire for Adolescents and the accelerometer data increased when the non-wear activity diary was included. Differences in the percentage of adolescents reaching the physical activity recommendations between the accelerometer data only and the accelerometer with the non-wear activity diary were significant. We conclude that if the non-wear activity diary data are not included, some adolescents could be misclassified as not being physically active according to the physical activity recommendations. It is therefore recommended to use a non-wear activity diary for gaining insight into the physical activity levels of individuals.     

Temporary contracts: effect on job satisfaction and personal lives of recent PhD graduates

In this study, we assess the effects of temporary employment on job satisfaction and the personal lives of recent PhD graduates. Temporary employment is becoming increasingly prevalent in many sectors, but has been relatively common in academia, especially for early career scientists. Labor market theory shows temporary employment to have a conspicuous negative influence on the job satisfaction and well-being of employees, but also identifies groups that may be exempt from these negative influences, such as the highly educated. Here, we study the effect of temporary employment on the highest educated group in the labor force, PhD graduates. We present findings of a survey of 1133 respondents who obtained their PhD from one of five Dutch universities between 2008 and 2012. Compared to PhDs employed on a permanent contract, PhDs on a temporary contract are less satisfied with their terms of employment, especially if they have no prospect of permanence. Temporary contracts with no prospect of permanence also decrease satisfaction with job content. Conversely, self-employment increases satisfaction with job content. Educational level required for the job also influences job satisfaction to a large degree: working below PhD level negatively affects job satisfaction. Finally, the type of contract affects different aspects of the personal lives of PhDs, such as the ability to obtain a mortgage, the stability of family life, and the possibility to start a family. In conclusion, we show that the highest educated, i.e., PhD graduates are not exempt from the negative influences of temporary employment.
