A horned member of the labyrinthodont super-family Brachyopoidea from the Early Triassic of Queensland

A horned, short-skulled labyrinthodont amphibian from the Arcadia Formation of the Rewan Group near Bluff, Queensland, is placed in the family Chigutisauridae of the superfamily Brachyopoidea. This is the first occurrence of this family outside Argentina. The material, consisting of two skulls and three mandibles is described as Keratobrachyops australis gen. et sp. nov., and used as a basis for an examination of the relationship between the families Brachyopidae and Chigutisauridae.     

Exploitation of groundwater in the oasis of Masāfī (UAE): A diachronic perspective

In order to understand the role of water resources in the establishment and long-term evolution of settlements investigated by the French Archaeological Mission in the UAE in the oasis of Masāfī, wells and springs of all periods, identified at the surface and in stratified contexts, were mapped and studied thanks to a multidisciplinary approach combining archaeology, geomorphology, geoarchaeology and ethnography. Our study demonstrates that:

• – The Masāfī oasis was located in a specific geological setting entailing the accumulation of groundwater resources at reachable depth.
• – The groundwater resources remained rather stable from the mid-second millennium BC to the second half of the twentieth century AD. In this respect, the apparent abandonment of the oasis during some periods cannot be explained by water depletion.
• – The groundwater resources have decreased sharply since the second half of the twentieth century AD, due to the introduction of new water extraction technologies, motor pumps and then drillings, as a result of the modernisation and industrialisation of UAE economy.

Our study also stresses the importance of well and spring irrigation in the development of the sedentary settlements in south-eastern Arabia, technologies that have often been neglected in the regional archaeological literature in favour of the qanāt.     

Performing national identities in everyday life: Popular motivations and national indifference in 19th-century Amsterdam

This article demonstrates how and when the nation—whether in the shape of concrete national symbols or as an abstract frame of reference—became relevant to ordinary people. It focuses on the experiences and activities of Amsterdam citizens in the second half of the 19th century. Central to the analysis is the apparent contradiction between ‘banal’ or ‘everyday nationalism’, in which nationalist symbols and rhetoric appeared to successfully reach their audience because of their omnipresence in daily life, and ‘national indifference’, as referring to the absence of national identification among the masses. It argues that in order to overcome the dichotomies between elites and masses and national and non-national performances, we should focus on the popular incentives for national identification, rather than on the ideological content and the (physical or symbolic) borders of the national community.     

Children’s participation in research on sensitive topics: addressing concerns of decision-makers

ABSTRACT

Although there is general agreement about children’s engagement in social research, some researchers continue to experience challenges when seeking approval and support for children’s participation from a range of adult stakeholders, particularly when the research involves a sensitive topic. These challenges may reflect different perspectives, conflicting interests, needs or expectations. This paper explores factors that influence the decision-making of key stakeholder groups, including Human Research Ethics Committees, parents and organisational representatives. Building on the kind of objective, rational reasoning that underpins much ethical decision-making, the findings, from interviews with 42 participants across stakeholder groups, draw attention to influential issues grounded in perceptions of: the institution and researcher undertaking the research; the project itself; children’s characteristics and contexts. Collectively, such issues point to the critically important role of mutually respectful relationships between researchers and stakeholders as the basis for designing and implementing ethical research that gives close attention to stakeholder concerns.
