ABSTRACT The representative bureaucracy literature asserts that minority personnel in public organizations can promote their social group either through their own behavior or by influencing other staff members or focal citizens. However, these phenomena have not been examined in wartime settings in ethnically homogeneous and heterogeneous organizations.

Performance of a UTC FW-4S solid propellant rocket motor under the command effects of simulated altitude and rotational spin [PDF]
One United Technology Center FW-4S solid-propellant rocket motor was fired at an average simulated altitude of 103,000 ft while spinning about its axial centerline at 180 rpm. The objectives of the test program were to determine motor altitude ballistic

Noisy Politics, Quiet Technocrats: Strategic Silence by Central Banks
ABSTRACT In contrast to the “quiet” politics of the pre‐2008 period, macroeconomic policy has become “noisy”. This break raises a question: How do independent agencies designed for quiet politics react when a contentious public turns the volume up on them?

ABSTRACT The Girls Excelling in Math and Science (GEMS) club is a long‐standing afterschool STEM program (1994–present). The study investigates the features of GEMS by exploring retrospective experiences of a group of original GEMS girls (OGGs) who attended GEMS in 1994–1995. Survey data were collected from 14 OGGs and in‐depth interview data from nine

Abstract The majority of Pleistocene figurative cave art in Western Europe consists of line drawings depicting large herbivores from the side view, and outlines were sometimes abbreviated to the head‐neck‐dorsal line. It is often assumed that the side view was used because it facilitates animal recognition compared to other views, and that abbreviated ...
