New Early Jurassic sawflies from Luxembourg: the oldest record of Tenthredinoidea [Hymenoptera: Symphyta]

Pseudoxyelocerus bascharagensis gen. et sp. nov., the oldest representative of the Tenthredinoidea and Xyelotomidae, based of a single forewing, and an enigmatic “Symphyta” family incertae sedis, based on a hindwing, are described from the Toarcian of Luxembourg. The relationships of the genera currently included in Xyelotomidae are briefly discussed. The genera Undatoma, Liaotoma, Leridatoma, and Davidsmithia have the unique apomorphy in the wing venation of the Tenthredinoidea minus Xyelotomidae. The Xyelotomidae is probably a paraphyletic family. Only a phylogenetic analysis will help to solve these problems. There is no evidence supporting the previous assignments of the fossil genera Vitimilarva and Kuengilarva to the family Xyelotomidae

Diet, hygiene and health in Roman period northern Gaul: A multidisciplinary study of a latrine from an artisan household in the vicus Orolaunum (Arlon, southern Belgium, c. 250–280 CE)

Botanical (macro remains and pollen) and animal remains, including intestinal parasites, from a latrine dated between c. 250 CE and 280 CE from the artisan quarter of the vicus Orolaunum (Arlon) have been studied. The results provide information on the diet and health of a non-elite and poorly understood part of the population in northern Gaul. The identified plant remains document a diet which include several Roman introductions to the region, but hardly any truly exotic imports. Also the remains of fish sauce have been identified, but this was a locally produced variety and possibly a cheaper version of the typical Mediterranean product. The results indicate that the diet of the household using the latrine was strongly influenced by romanisation and that the lack of exotic imports was most likely the result of a low economic status rather than a lack of interest for these products. The people using the latrine were also infected with both roundworm and whipworm, two intestinal parasites that were probably common in the population of northern Roman Gaul and which are spread when sanitation is ineffective

Sustainability, design futuring, and the process of shelter and settlements

The need for adequate shelter and resettlement solutions for the growing number of displaced people worldwide is a problem of such magnitude that adequate solutions currently elude us. Humanitarian organisations are calling for greater engagement from experts who are able to assist with this crisis, including built environment professionals such as architects. With vague career pathways and a lack of exposure to this crucial area of practice in architects’ formative years, further education and postgraduate studies targeting humanitarian practice have only recently begun to emerge. This research reviews current literature in the areas of shelter and settlements, illustrating that the architectural profession has a responsibility to contribute towards positive resettlement outcomes for displaced populations. This paper also discusses a particular area of theory known as 'Design Futuring' by Tony Fry, exploring how it can provide a theoretical framework to support engagement from architects in both research and education targeting this area of practice. The paper identifies key areas of conceptual overlap including the emphasis on sustainability, shelter and design processes in favour of product thinking, and the reframing of a more collaborative and transdisciplinary approach to architectural practice. It is anticipated that this research can inform approaches to architectural education and research focusing on shelter and settlements design, representing a new area of theory-based inquiry
