How lava flows: New insights from applications of lidar technologies to lava flow studies
, 2013 Mafic lava flows are common; for this reason, they have long been a focus of volcanological studies. However, field studies of both older and active flows have been hampered by difficulties in field access; active flows are hot, whereas older flows have ...

Toward a model for leveed lava flows [PDF]
Many lava flows have two distinct volumetric components during emplacement. First, there is a component actively flowing in accordance with Newtonian or other constitutive relations.

“The Excuses We Make”: Defining Eight Corruption Rationalization Categories
Regulation &Governance, EarlyView.ABSTRACT The rationalization of corruption allows individuals to detach from moral imperatives, enabling them to perceive unethical or unlawful actions as acceptable or justifiable.

Studies of fluid instabilities in flows of lava and debris [PDF]
At least two instabilities have been identified and utilized in lava flow studies: surface folding and gravity instability. Both lead to the development of regularly spaced structures on the surfaces of lava flows. The geometry of surface folds have been

Sedimentology, EarlyView.ABSTRACT Structurally controlled hydrothermal dolomitization, commonly driven by high‐pressure, high‐temperature fluid–rock reactions, offers insights into the tectonic evolution of sedimentary basins and the geochemical composition of their diagenetic fluids.

Sedimentology, EarlyView.ABSTRACT Tubular and curviplanar structures, outlined by the occurrence of haematite/goethite, chlorite, quartz and albite, are developed in the Middle Permian Broughton Formation in the southern Sydney Basin, New South Wales, Australia. These structures are interpreted as fluid‐flow pathways resulting from the ejection of heated pore fluids as a thick

Perception of civil service corruption and trust in political institutions in Brazil
Sociological Forum, EarlyView.Abstract Trust in political institutions represents a central facet of political legitimacy in a democracy. A vast literature suggests that the local perception of corruption lowers trust in political institutions in different research settings. Building upon this literature, we explore whether the perception of civil service corruption and trust in ...
