Intervention programme to prevent bullying in adolescents in physical education classes (PREBULLPE): a quasi-experimental study

ABSTRACT

Background: Bullying is a social problem where there is a phenomenon of intentional aggression that occurs in all schools. It has multiple negative consequences for the victim’s psychological health. As school is a context for learning about life in society, strategies to prevent such attitudes and behaviours should be encouraged. Although some studies seem to indicate the potential of the subject of physical education to promote attitudes and behaviours against bullying, there is still insufficient scientific evidence to deduce a positive impact on the reduction or prevention of this phenomenon.

Purpose: This study aimed to analyse the effectiveness of a specific intervention to prevent bullying in Physical Education classes in Secondary Education. 6 specific sessions inserted into the physical education curriculum to find out what bullying is, who its protagonists are and how to prevent it.

Participants and setting: In the study, 764 students with an age range of 12–19 years (49.3% girls; age mean [M]?=?14.80, standard deviation [SD]?=?1.69) from two public educational centres participated. Among them, 439 were randomly assigned to the quasi-experimental group (48.1% girls; age M?=?14.70, SD?=?1.59) and 325 to the control group (51.1% girls; age M?=?14.94, SD?=?1.83). Data were collected at two timepoints, pre- and the post-intervention data.

Data collection: The Spanish version of the European Bullying Intervention Project Questionnaire (EBIPQ) was used to measure the incidence of bullying. To measure cyberbullying, the Spanish version of the European Cyberbullying Intervention Project Questionnaire (ECIPQ) scale was used.

Data analysis: The Student t-test was performed to compare possible differences between the experimental and control groups in the pre-test. To compare the means of the factors obtained based on the variables and the instruments used, as well as the scores obtained from the subjects of the experimental and control groups at the two timepoints, linear models of repeated measurements have been established comparing the pre- and post-intervention moments and the experimental and control groups, introducing sex and grade variables to compare the effectiveness of the programme based on them.

Results: There were no differences in the pre-test measurements in any of the variables. After the intervention programme in the quasi-experimental group, the bullying victimisation (F?=?16,951; p?=?.000) and bullying aggression (F?=?5,215; p?=?.023) rates decreased significantly more than they did the control group. Likewise, victimisation in cyberbullying (F?=?6,234; p?=?.013) decreased significantly differently, but aggression in cyberbullying did not (F?=?0,099; p?=?.753).

Conclusion: The implementation of a specific intervention to prevent bullying inserted into the physical education curriculum seems to have decreased bullying and cyberbullying victimisation.

It's Not Just Angoff: Misperceptions of Hard and Easy Items in Bookmark-Type Ratings

A common belief is that the Bookmark method is a cognitively simpler standard-setting method than the modified Angoff method. However, a limited amount of research has investigated panelist's ability to perform well the Bookmark method, and whether some of the challenges panelists face with the Angoff method may also be present in the Bookmark method. This article presents results from three experiments where panelists were asked to give Bookmark-type ratings to separate items into groups based on item difficulty data. Results of the experiments showed, consistent with results often observed with the Angoff method, that panelists typically and paradoxically perceived hard items to be too easy and easy items to be too hard. These perceptions were reflected in panelists often placing their Bookmarks too early for hard items and often placing their Bookmarks too late for easy items. The article concludes with a discussion of what these results imply for educators and policymakers using the Bookmark standard-setting method.     

Why People Dual Screen Political Debates and Why It Matters for Democratic Engagement

Dual screening during televised election debates is a new domain in which political elites and journalists seek to influence audience attitudes and behavior. But to what extent do non-elite dual screeners seek to influence others, particularly their social media followers, social media users in general, and even politicians and journalists? And how does this behavior affect short- and longer-term engagement with election campaigns? Using unique, event-based, panel survey data from the main 2015 UK general election debate (Wave 1 = 2,351; Wave 2 = 1,168) we reveal the conditions under which people experience agency, empowerment, and engagement now that social media have reconfigured broadcast political television.

讲大局思想是邓小平理论的重要组成部分.讲大局是党性原则的体现,是讲政治的起码要求;讲大局是传统美德的折射,是讲正气的重要内涵;讲大局是辩证思维的反映,是科学的方法论.自觉学习、正确把握和运用邓小平理论中的讲大局思想,对于深入开展"三讲"教育,提高干部队伍素质,把建设有中国特色社会主义伟大事业不断推向前进,具有十分重大的现实意义.     

A comparison of haemolytic responses in fore-foot and rear-foot distance runners

This study examined the haemolytic effects of an interval-based running task in fore-foot and rear-foot striking runners. Nineteen male distance runners (10 fore-foot, 9 rear-foot) completed 8 × 3 min repeats at 90% vVO_2peak on a motorised treadmill. Pre- and post-exercise venous blood samples were analysed for serum haptoglobin to quantify the haemolytic response to running. Vertical ground reaction forces were also captured via a force plate beneath the treadmill belt. Haptoglobin levels were significantly decreased following exercise (P = 0.001) in both groups (but not between groups), suggesting that the running task created a haemolytic stress. The ground reaction force data showed strong effect sizes for a greater peak force (d = 1.20) and impulse (d = 1.37) in fore-foot runners, and a greater rate of force development (d = 2.74) in rear-foot runners. The lack of difference in haptoglobin response between groups may be explained by the trend for fore-foot runners to experience greater peak force and impulse during the stance phase of their running gait, potentially negating any impact of the greater rate of force development occurring from the rear-foot runners’ heel strike. Neither type of runner (fore-foot or rear-foot) appears more susceptible to technique-related foot-strike haemolysis.

Physical and psychomotor performance of Australian football and rugby league officials during a match simulation

The onset of exercise facilitates an improvement in psychomotor performance until the second ventilatory threshold, after which performance is reduced. This inverted-U relationship appears valid for incremental and steady-state exercise, however, not for intermittent exercise. This study examined changes in psychomotor performance of team sport officials during a laboratory-based match simulation. Twelve elite Australian football (n = 5) and rugby league (n = 7) officials (32.5 ± 5.5 years; 180.0 ± 6.8 cm; 78.8 ± 7.6 kg) completed the match simulation on a non-motorised treadmill. Physiological measures were routinely taken, while psychomotor performance was assessed using the Eriksen flanker task (multiple-choice response time). Significant reductions (P < 0.05) were observed in distance covered and high-speed running during the second half when compared to the first. No significant differences (P > 0.05) in psychomotor performance at different time points were observed. Response time was significantly improved when running above 65% of maximal sprinting speed (P < 0.01). This data questions the application of the inverted-U hypothesis for intermittent exercise and suggests that the short high-intensity efforts may not result in the same physiological events that limit psychomotor performance during sustained high-intensity exercise. More so, the high-intensity efforts during the match protocol appeared to promote psychomotor performance during the intermittent exercise.
