Sighted volunteers’ motivations to assist people with visual impairments in freetime sport activities

Since the changing of the political and economic system in 1989-1990 in Hungary, volunteer movements have appeared all over the country. Volunteers of different ages and socioeconomic backgrounds are engaged in a wide range of activities, wishing to add values to the lives of others in need, hoping to improve their micro or/and macro environment. Volunteering has also appeared in the field of sport, and the work of a large number of nongovernmental sport organisations is strongly dependent on volunteers’ participation. In the socialist era disability sports were neglected by the state. The new democratic state has been paying increasing attention to disability sports and volunteers have been a great asset in improving the accessibility of spare time sport activities. The present empirical research investigates which factors motivate sighted volunteers to join Hungarian Sports and Leisure Association for the Visually Impaired (Látássérültek Szabadidős Sportegyesülete, LÁSS). Results confirm that joining LÁSS was in few cases (N=3) attributed to having parental or other family relations with blind or partially sighted people. Respondents unanimously admit to have a wish to share the joy of physical activity with their visually impaired peers.

A highly resistive layer within the crust of X-ray pulsars limits their spin periods

The lack of isolated X-ray pulsars with spin periods longer than 12 s raises the question of where the population of evolved high-magnetic-field neutron stars has gone. Unlike canonical radiopulsars, X-ray pulsars are not subject to physical limits to the emission mechanism nor observational biases against the detection of sources with longer periods. Here we show that a highly resistive layer in the innermost part of the crust of neutron stars naturally limits the spin period to a maximum value of about 10–20 s. This highly resistive layer is expected if the inner crust is amorphous and heterogeneous in nuclear charge, possibly owing to the existence of a nuclear ‘pasta’ phase. Our findings suggest that the maximum period of isolated X-ray pulsars may be the first observational evidence for an amorphous inner crust, whose properties can be further constrained by future X-ray timing missions combined with more detailed models.
