Many difficulties learners have with rational number tasks can be attributed to the “natural number bias”, i.e. the tendency to inappropriately use natural number properties in rational numbers tasks (Van Hoof, 2015). McMullen and colleagues found a relevant source of individual differences in the learning of those aspects of rational numbers that are susceptible to the natural number bias, namely Spontaneous Focusing On quantitative Relations (SFOR) (McMullen, 2014). While McMullen and colleagues showed that SFOR relates to rational number knowledge as a whole, we studied its relation with several aspects of the natural number bias. Additionally, we 1) included test items addressing operations with rational numbers and 2) controlled for general mathematics achievement and age. The results showed that SFOR related strongly to rational number knowledge, even after taking into account several control variables. The results are discussed for each of the three aspects of the natural number bias separately.

The aim of the article, which processes the results of ethnographic research, is to interpret, with the example of the emergence and disappearance (transformation) of the Alternative Bloc network, the significance and functioning of fractions and networks of co-operation on the meso-mobilisation level in the LGBTQ movement in Spain. The study takes its departure from a characterisation of the movement as an ideologically polarised non-unified whole. Within that context, active fractions criticise the official politics of the state-supported Federation of LGBTQ Organisations and by means of protest campaigns, based on co-operation between ideologically related platforms of social movements in internationally supported networks, demand civic rights for all irrespective of sexual or gender identity. Even despite the disunity and antagonistic character of the protest actions, the newly-emerged networks cooperating on an international level have had a positive impact on the orientation and continuity of the entire LGBTQ movement in the country.
