This article is based on an EAA session in Kiel in 2021, in which thirteen contributors provide their response to Robb and Harris's (2018) overview of studies of gender in the European Neolithic and Bronze Age, with a reply by Robb and Harris. The central premise of their 2018 article was the opposition of ‘contextual Neolithic gender’ to ‘cross-contextual Bronze Age gender’, which created uneasiness among the four co-organizers of the Kiel meeting. Reading Robb and Harris's original article leaves the impression that there is an essentialist ‘Neolithic’ and ‘Bronze Age’ gender, the former being under-theorized, unclear, and unstable, the latter binary, unchangeable, and ideological. While Robb and Harris have clearly advanced the discussion on gender, the perspectives and case studies presented here, while critical of their views, take the debate further, painting a more complex and diverse picture that strives to avoid essentialism.
Several studies suggest significant relationships between migration and autism spectrum disorder (ASD) but there are discrepant results. Given that no studies to date have included a pathological control group, the specificity of the results in ASD can be questioned.
To compare the migration experience (premigration, migratory trip, postmigration) in ASD and non-ASD pathological control groups, and study the relationships between migration and autism severity.
Parents’ and grandparents’ migrant status was compared in 30 prepubertal boys with ASD and 30 prepubertal boys without ASD but with language disorders, using a questionnaire including Human Development Index (HDI)/Inequality-adjusted Human Development Index (IHDI) of native countries. Autism severity was assessed using the Child Autism Rating Scale, Autism Diagnostic Observation Schedule and Autism Diagnostic Interview-Revised scales.
The parents’ and grandparents’ migrant status frequency did not differ between ASD and control groups and was not associated with autism severity. The HDI/IHDI values of native countries were significantly lower for parents and grandparents of children with ASD compared with the controls, especially for paternal grandparents. Furthermore, HDI/IDHI levels from the paternal line (father and especially paternal grandparents) were significantly negatively correlated with autism severity, particularly for social interaction impairments.
In this study, parents’ and/or grandparents’ migrant status did not discriminate ASD and pathological control groups and did not contribute either to autism severity. However, the HDI/IHDI results suggest that social adversity-related stress experienced in native countries, especially by paternal grandparents, is potentially a traumatic experience that may play a role in ASD development. A ‘premigration theory of autism’ is then proposed.
Imaging debris discs in the L′-band (3.8 μm) is a difficult task. Quasi-static speckles from imperfect optics prevail below 1″ whereas background emission is the dominant noise source beyond that separation and is much larger than at shorter wavelengths. We demonstrate here the potential of the newly commissioned AGPM coronograph on VLT/NaCo combined with advanced star and sky subtraction technique based on Principal Component Analysis, and we analyze the morphology of the β Pictoris disc.
