In emergency care research, it may be the case that neither informed consent nor surrogate consent is possible. In order to nonetheless allow for such research, codes and regulations of research ethics have increasingly incorporated provisions regarding this specific situation. The protection that those provisions offer need to be better understood. This article addresses in what ways they protect

This paper discusses contextual aspects of pottery from the two early Neolithic Funnel Beaker(TRB) sites Resmo and Runsbäck, on the island of Öland, SE Sweden. The sites are situated 15kmapart on the west side of the island and the C14 dates place the activities at the sites at c. 3900––3600BC and 3600––3100 BC respectively, possibly with some overlap.

Practice theory roughly argues that the material world and the cultural world continuously interact and co-constitute one another. However, existing research methods on consumer behaviors tend to separatethese two dimensions and show a preference toward concentrating on only one of them. Video ethnography as a medium has the potential to capture these two worlds—to combine the symbolic and materia

This research examines the practices of consumers that are made possible by a 'low-end' street, and how these shopping practices in turn shape and maintain a high street at the urban margins. It locates itself within the academic inquiries of cultural geographies of retail.Södergatan is the field of the study, the main shopping street in the stigmatized southern part of city of Helsingborg in Swed

We are seeing today an increased interest in ethics, the environment, and social responsibility at the same time as the individual is expected, in different ways, to realize him-/herself through consumption. These interests coincide with the establishment of ethical markets for re-use and second-hand. In this paper we investigate and map out the ethical shopping spaces in Helsingborg, and how thes

Hydrodynamic cavitation that occurs inside valves not only increases the energy consumption burden of the whole piping system but also leads to severe damages to the valve body and the piping system with a large economic loss. In this paper, in order to reduce the hydrodynamic cavitation inside globe valves, effects of valve body geometrical parameters including bending radius, deviation distance,

The epidermis of aerial plant organs is thought to be limiting for growth, because it acts as a continuous load-bearing layer, resisting tension. Leaf epidermis contains jigsaw puzzle piece-shaped pavement cells whose shape has been proposed to be a result of subcellular variations in expansion rate that induce local buckling events. Paradoxically, such local compressive buckling should not occur

We ask what caused poverty to decline in Brazil over the last decade. Our contribution lies in the introduction of a structural change perspective to assess the evolution of poverty by considering the sectoral impact of growth and the social policies at the federal, state and municipal level. We confirm previous findings in the literature that the service sector rather than agriculture contributes

Apicobasal polarity is known to affect epithelial morphogenesis and cell differentiation, but it remains unknown how these processes are mechanistically orchestrated. We find that ligand-specific EGFR signalling via PI(3)K and Rac1 autonomously modulates apicobasal polarity to enforce the sequential control of morphogenesis and cell differentiation. Initially, EGF controls pancreatic tubulogenesis
