Resumen. En recientes modelos económicos, un optimista (no Bayesiano) es aquel agente cuyas creencias y expectativas están frecuentemente «tintadas de rosa», dado que sus a prioris y la evidencia objetivamente disponible implicarían una predicción estadística menos positiva.

ABSTRACT: Migrants’ healthcare entitlement represents a conflictive issue in the political battlefield, with research pointing towards the determinant role of party politics in determining policy outputs. Addressing the 2012 healthcare reform and 2018 counter-reform adopted in Spain by a right-wing and left-wing government respectively and drawing on qualitative analysis of parties’ discourses and policy measures, we argue that ideological differences along the healthcare-migration nexus were overemphasised to play symbolic politics.

Abstract. Author co-citation analysis (ACA) is a commonly used method to map knowledge domains and depict scientific intellectual structures. Although all authors’ information has been considered in previous studies, ACA does not distinguish credits of different collaborators within a team. Authors’ sequence in a publication illustrates their contributions and specialty of research, which offers more information as inputs of ACA. This paper considers author sequence in ACA and proposes a sequence-based ACA method.

Abstract. The geographies of differences and resistances consist of experiences, processes, and visions of people in a distinctive space, expressed through everyday actions and behaviors to stay in a place. The distinctive spaces analyzed represent depopulated rural areas and urban ruralities, namely, (i) rural spaces with historical population losses, (ii) processes of socioeconomic decline, and (iii) lifestyles and rural spaces in urban contexts, both associated with actions and strategies of difference and daily resistance of people.
