Acting on the Voicelessness Challenge to Democratic Deliberation: A Six‐Actor Framework

Bioethics, EarlyView.
ABSTRACT Political philosophers have long recognized that key stakeholders in policy decisions—children, future generations, nonhuman animals, and individuals with severe cognitive impairments—are structurally unable to participate in the deliberative processes meant to legitimate those decisions.

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

Boreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Palaeoglaciations in the Polar and Subpolar Ural Mountains

Boreas, EarlyView.
The Ural Mountains form a major physiographic boundary between the East European Plain and West Siberia, both repeatedly glaciated during the Pleistocene by the Barents–Kara ice sheet. Although the present‐day topography reflects significant glacial modification, the extent, chronology and interaction of mountain glaciers with the Barents–Kara ice ...

LGM glaciation in the northern Dinaric Mountains, Slovenia: new insights from terrestrial cosmogenic nuclide dating and Parallel Ice Sheet Model simulation

Boreas, EarlyView.
The Dinaric Mountains are a mountain range stretching NW–SE from the Alps to the Albanides–Hellenides in central Europe. The highest parts were occupied by small ice fields and/or valley glaciers during the Quaternary cold periods, while even today some small glaciers still exist in topoclimatically favourable areas.

Amalgam onlay restoration

, 1991
This article discusses a conservative class II amalgam cavity preparation that is similar to a cast onlay preparation except for the absence of the lingual and facial bevels.
