Automatic path planning for an unmanned drone with constrained flight dynamics

In the article we solve path planning task for an agent being multirotor unmanned aerial vehicle (multicopter). We propose an approach of estimating path geometry constraints based on UAV flight dynamics model and control constraints. Than we introduce a new path finding method which takes into consideration those geometry constraints and study this method both theoretically and empirically.     

The effect of smartphones and playing video games on decision-making in soccer players: A crossover and randomised study

ABSTRACT

The objective of this study was to analyse the effect of the use of social networks in smartphones or playing video games on the passing decision-making performance in professional soccer athletes. Participants were 25 male professional soccer athletes (mean ± SD: age 23.4 ± 2.8 years). The participants performed three randomised conditions divided into three groups: control (CON), smartphone (SMA), and video game (VID). Before and after each experimental condition, the Stroop Task assessed the level of induced mental fatigue. Then, the athletes performed a simulated soccer match. A CANON® camera recorded the matches for further analysis on passing decision-making performance. A group effect was identified (p < .01) with impairment on passing decision-making performance for the SMA (p = .01, ES = 0.5) and VID (p = .01, ES = 0.5) conditions. We concluded that the use of social networks on smartphones and/or playing video games right before official soccer matches might impair the passing decision-making performance in professional soccer athletes.

‘They think that if you're a teacher here … you're not clever enough to be a proper teacher’: the courtesy stigma experienced by teachers employed at schools for pupils with behavioural,emotional and social difficulties (BESD)

A wealth of literature has identified that children with behavioural, emotional and social difficulties (BESD) and their families are frequently stigmatised due to the perceived controllable and ‘invisible’ nature of this special educational need (SEN). Yet little research has considered the impact of this stigma on another group of individuals, educational practitioners employed in BESD schools. This is despite these professionals working in close contact with pupils with BESD, a heavily stigmatised group, on a regular basis. This paper therefore, details a study which explored perceptions of stigma specifically with educational professionals employed in schools for pupils with BESD. Semi‐structured interviews with nine practitioners (including head teachers and class teachers with additional responsibilities) were conducted, all of whom had worked within the BESD sector for at least 10 years, with data being analysed via Interpretative Phenomenological Analysis (IPA). Findings revealed how educational practitioners employed in BESD schools experienced courtesy stigma, with many not being perceived as ‘proper’ teachers due to a discourse of care surrounding BESD. Other professionals reported much confusion from their mainstream colleagues and other individuals about how they could want to work with such ‘challenging’ pupils. This courtesy stigma was linked to the wider stigma surrounding BESD schools, which were often ignorantly perceived to be full of ‘bad boys’ or ‘absolute horrors’. This paper concludes by considering the implications of these findings for policy and practice, and provides recommendations for addressing the identified stigma towards practitioners employed in BESD schools.     

Outstanding performances during elite-standard short and middle-distance finals and the hyperandrogenism regulation—A detailed analysis of Caster Semenya’s results

ABSTRACT

Recently, there has been much controversy over the International Association of Athletics Federation (IAAF) regulations regarding eligibility to compete and natural testosterone levels in female athletes. Much interest lies in the analysis of Caster Semenya's extraordinary performance. The objective of this work were, a) Complete an analysis of Caster Semenya's results during the 800m finals and b) search for existing similar performances by other female athletes. We analysed the results of the finals of all IAAF World Championships and Olympic Games from 1984–2016, including the 800m results of the Diamond Leagues 2016–2018. Exponential curves were fit to the data to characterise and predict performance for each event. Caster Semenya's finishing times before her ineligibility to compete and after the suspension of the IAAF hyperandrogenism regulation were found to be 1.24% and 1.49%, respectively, faster than the characteristic performance of the elite-standard in the women’s 800m final. Other female athletes, with finishing times faster than the ones predicted by the characteristic curves were also discovered. The percentage difference in performance between Caster Semenya and the other participants did not reach 3% in the 800m event. No conclusions can be drawn regarding extraordinary results ever performed during the 100m, 200m or 400m finals.     

Examining the Treatment Validation Consultation Model

The present article explores the utility and feasibility of treatment validation consultation (TVC). Although evidence exists for behavioral consultation, few findings have been reported for TVC. TVC is based on core components of behavioral consultation, but has several unique characteristics. In this article, TVC is situated within the behavioral consultation literature; one case study is used to demonstrate TVC’s utility and feasibility; and considerations for future TVC research are explored.
