It can be a “very fine line”: professional footballers’ perceptions of the conceptual divide between bullying and banter

This study explores professional footballers’ perceptions of where banter crosses the conceptual line into bullying. The study’s focus is of importance, given the impact that abusive behaviors have been found to have on the welfare and safeguarding of English professional footballers. A phenomenological approach was adopted, which focused on the essence of the participants’ perceptions and experiences. Guided by Interpretative Phenomenological Analysis (IPA), individual semi-structured interviews (MDuration = 44.10 min, SD = 10.81) were conducted with 18 male professional footballers (Mage = 19.83 years, SD = 2.96) from three Premier League and Championship football clubs. The findings from this study revealed several key superordinate themes in relation to the dividing line between bullying and banter. These themes included “perception,” “intentionality,” “detecting the line,” and “having a bit of banter.” The findings demonstrate how perceptions of bullying and banter are nuanced by individual differences among the players and the culture of the professional football context. Specifically, it was found that the professional football context can legitimize forms of humor blurring the lines between bullying and banter, challenging the typically positive view of the concept of banter in this environment. From an applied perspective, these findings highlight the need for coaches, players, and football clubs more broadly to address cultural expectations around banter in their environment, while educating individuals around their own perceptions of bullying and banter

Promotion of Physical Activity Using Point-of-Decision Prompts in Berlin Underground Stations

To evaluate point-of-decision prompts in the promotion of stair use in Germany, motivational posters were placed at three underground stations in Berlin. The proportion of passengers using stairs or stairways was counted before, during installation, and two weeks after removal of posters. In total, 5,467 passersby were counted. Stair use increased significantly in women, but not in men. The present pilot study thereby shows that the use of point-of-decision prompts is also feasible in Germany and it provides some evidence of effectiveness. Methodologically rigorous studies are warranted to confirm these findings

Continuous Free Cortisol Profiles in Healthy Men - Validation of Microdialysis Method

Abstract Context In humans, approximately 95% of circulating cortisol is bound to corticosteroid-binding globulin and albumin. It is only the free fraction that is biologically active and can activate signalling pathways via glucocorticoid hormone receptors in cells. Microdialysis is a well-established technique that enables the sampling of molecules in different compartments of the body, including extracellular fluid. This is the first study validating a rapid sampling microdialysis method measuring free cortisol in the subcutaneous and blood compartments of healthy volunteers. Methods Healthy non-smoking volunteers (42 men; age 18-24 years; BMI 18-25 kg/m2) received placebo (saline), 250 µg Synacthen or 1 mg dexamethasone with ten minutely sampling to measure total and free cortisol (subcutaneous, intravenous and saliva) for an hour before and 4 hours after administration. Results Following stimulation by Synacthen, total serum cortisol and free cortisol in both compartments rose significantly, achieving and maintaining maximum levels between 2 and 3 hours following the stimulus. A decline in cortisol levels was evident after the administration of dexamethasone or placebo, but there was a clear pulsatile activity around lunchtime in the latter group which was prominent in the blood compartment (total and free cortisol). There was good correlation between serum total and free cortisol (SC and intravenous) in the Synacthen and dexamethasone groups with no significant delay (less than 5 minutes) between total and free cortisol. Conclusions This seminal study demonstrated the dynamic responses of total blood cortisol and microdialysis derived free cortisol in blood, subcutaneous tissue and saliva in man. </jats:sec

Sense of control and adolescents’ aggression: the role of aggressive cues

The misperception of aggressive cues is considered a risk factor for inducing adolescent aggression. Poor coping with life stress is also considered a major influence on aggression. The current study examined the relationship between subjective sense of control and adolescent aggression, considering influences upon the perception of these aggressive cues. In Study 1, 60 participants took part in a 2 (sense of control: high sense of control vs. low sense of control)x2 (aggressive cue: aggressive vs. neutral) between-subjects contextual experiment. The result found that a lower sense of control led to an increase in adolescents&#39; aggression; only in the low-sense-of-control condition did exposure to aggressive cues boost aggression. In Study 2, the catalytic effect of aggressive cues was further explored by an experiment in which 40 adolescents were randomly assigned to a low- or high-sense-of-control condition to test the importance of aggressive cues. The results suggest that adolescents in the low-sense-of-control condition show a higher salience for aggressive cues.</p

Measurement of the cross-section and charge asymmetry of WW bosons produced in proton-proton collisions at s=8\sqrt{s}=8 TeV with the ATLAS detector

This paper presents measurements of the $W^+ \rightarrow \mu^+\nu$ and $W^- \rightarrow \mu^-\nu$ cross-sections and the associated charge asymmetry as a function of the absolute pseudorapidity of the decay muon. The data were collected in proton--proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS experiment at the LHC and correspond to a total integrated luminosity of 20.2~\mbox{fb^{-1}}. The precision of the cross-section measurements varies between 0.8% to 1.5% as a function of the pseudorapidity, excluding the 1.9% uncertainty on the integrated luminosity. The charge asymmetry is measured with an uncertainty between 0.002 and 0.003. The results are compared with predictions based on next-to-next-to-leading-order calculations with various parton distribution functions and have the sensitivity to discriminate between them.Comment: 38 pages in total, author list starting page 22, 5 figures, 4 tables, submitted to EPJC.
