New insights into the neolithisation process in southwest Europe according to spatial density analysis from calibrated radiocarbon dates
The agricultural way of life spreads throughout Europe via two main routes: the Danube corridor and the Mediterranean basin. Current archaeological literature describes the arrival to the Western Mediterranean as a rapid process which involves both demic and cultural models, and in this regard, the dispersal movement has been investigated using mathematical models, where the key factors are time and space. In this work, we have created a compilation of all available radiocarbon dates for the whole of Iberia, in order to draw a chronological series of maps to illustrate temporal and spatial patterns in the neolithisation process. The maps were prepared by calculating the calibrated 14C date probability density curves, as a proxy to show the spatial dynamics of the last hunter-gatherers and first farmers. Several scholars have pointed out problems linked with the variability of samples, such as the overrepresentation of some sites, the degree of regional research, the nature of the dated samples and above all the archaeological context, but we are confident that the selected dates, after applying some filters and statistical protocols, constitute a good way to approach settlement spatial patterns in Iberia at the time of the neolithisation process

Impact of Affective Profiles on School Refusal in a Spanish Sample of Primary Education
Although the study of affective profiles has generated great interest in recent years, no investigations were found that analyze their relationship with school refusal. The present study identified the affective profiles arising from combining positive affect (PA) and negative affect derived from the 10-item Positive and Negative Affect Schedule for Children (PANAS-C) and determined the existence of significant differences between the found affective profiles in school refusal measures obtained from the School Refusal Assessment Scale Revised for Children (SRAS-R-C) in a sample of 1575 Spanish students (aged 8–11 years). On the one hand, cluster analyses confirmed the four affective profiles: Self-Fulfilling Profile (high PA and low NA), High Affective Profile (moderately high PA and high NA), Low Affective Profile (low PA and NA) and Self-Destructive Profile (low PA and high NA). On the other hand, post hoc contrasts showed that students from the Self-Destructive Profile scored significantly higher in the first three factors and the total score of the SRAS-R-C in comparison with the rest of profiles. Conversely, the Self-Fulfilling Profile obtained significantly higher scores in the fourth factor of the SRAS-R-C in comparison with the Low Affective and Self-Destructive Profiles. Due to the fact that the first three factors of the SRAS-R-C have been related with the presence of anxious or depressive symptomatology, the results of this manuscript confirmed that the Self-Destructive Profile is the most maladaptive affective profile and it is important to control and reduce the negative emotional reactions expressed by students in school situations.This work was supported by the Ministry of Science and Innovation of Spain [EDU2012-35124]; the University of Alicante [UA FPU, 2015-5995] [GRE16-07]; and the Ministry of Education, Research and Sport of Valencia [VALi + d, ACIF-2014-368]
