Sporting Recommendations for Teaching Fair Play: A Logical and Evolutionary Account

In this paper I argue for a cross-disciplinary approach to teaching sport ethics. I call this a logical and evolutionary account because information that emanates from cell biology, anthropology, philosophy and everywhere in between, I claim, is needed in developing effective fair play pedagogies. The gist of the argument is this: We need to teach smarter, not just harder. Teaching smarter, I say, comes from an understanding of human nature and the logic of sport. I discuss animal behavior, emotions, genetic predispositions, human evolution, the structure of games, philosophical idealism, and other factors in producing five recommendations for teaching sport ethics.

Abstract

A pasture-based system for dairy cattle is not common due to the need for milking, despite the fact that this system provides the possibility of natural animal behaviour. Six behavioural observations were carried out during the grazing season in dairy herds bred in a mountainous area (700 m a. s. l.) The basic herd was comprised of 53 cows, mainly of the Holstein breed. From April to November the herd was located on pastures near the stables and milked twice a day in a tandem milking parlour. Feed ration was composed of pasture and concentrated feed in the stable. During the grazing season, there was a slight variation with a tendency to extend the grazing period to the autumn months. The cattle grazed the shortest time in May - 35.0% of the day or 8.4 hours. In the autumn months the grazing time increased by 2.2 and 2.6 hours respectively. Cows were resting the longest time period in May and June (8.9 and 9.1 h respectively). On the other hand, cows were resting for the shortest time in October (6.8 hours). During the grazing period the milk yield decreased from 20.4 kg in April to 14.4 kg in November.

Abstract

The existence of extensive records for the impact of night sky brightness on the animals’ behavior in their natural environment shows the need to investigate the level of artificially induced night sky glow (light pollution) in the protected areas.

The results of multi-night sky brightness measurements carried out at the selected sites in Polish mountain areas under various atmospheric conditions are presented. Conducted measurements show a strong impact of the artificial sky glow on the night sky brightness, which is the essence of light pollution. The influence of both distant urban centers, as well as local tourist resorts on the size of studied phenomenon in the mountain areas, which causes both ecological and touristic degradation of these areas was stated. In a few studied areas the level of night sky brightness greatly exceeds the natural one and is comparable to such levels measured inside the cities. It was found that only the southern part of the Polish Carpathians can be considered an area free of light pollution.

Endocrinological and Behavioural Effects of Chronic Fluxilan Administration in Rats

Chronic stress induces changes in the neuroendocrine and neuronal system, including elevation of catecholamines and corticosterone (CORT) levels, and could be an important factor in initial depression. Antidepressants affect monoaminergic neurotransmission and modulate central neuropeptides involved in the coordination of stress response and the control of HPA axis activity. We studied the effects of chronic treatment with fluxilan, a selective inhibitor of serotonin reuptake, in unstressed controls and chronic unpredictable mild stress (CUMS) rats, on behaviour and plasma noradrenaline (NA), adrenaline (A), corticosterone (CORT) and adrenocorticotropic hormone (ACTH). CUMS did not affect plasma NA, A and ACTH, but elevated plasma CORT content. Plasma concentration of catecholamines after fluxilan administration was significantly increased in control and CUMS group. On the other hand, fluxilan expressed no effect on plasma ACTH and CORT concentrations in control animals, but decreased ACTH and CORT levels in CUMS animals. Behaviourally, fluxilan treated animals displayed enhanced anxiety. The results demonstrate that the anxiogenic effects of chronic fluxilan administration are similar to those reported by many other studies. The findings described here suggest that elevated plasma catecholamines may contribute to an adverse effect of this drug on cardiovascular parameters during antidepressant therapy.
