A long duration robotic presence on lunar and planetary surfaces will allow the acquisition of scientifically interesting information from a diverse set of surface and sub-surface sites. The wide range of terrain types including plains, cliffs, sand dunes, and lava tubes will require the development of robotic systems that can adapt to possibly rapidly changing terrain. These systems include si...

Two case studies are presented involving fatal falls of adult females from a height. One involved a launch at low speed from a balcony, and one involved a launch at high speed from the top of a cliff. Crime scene evidence obtained on the balcony itself provided a strong indication of homicide, but subsequent investigation showed that the fall was accidental. No crime scene evidence was obtained...

The ‘glass cliff’ posits that when women achieve high profile roles, these are at firms in precarious positions. Previous research analysed appointments (male/female), estimated the precariousness of firms involved and drew inferences about the glass cliff. This study is different as it directly tests the relationship between a precarious situation and changes in board gender diversity. The sam...

Ecologists often use mark-recapture to estimate demographic variables such as abundance, growth rate, or survival for samples of wild animal populations. A common assumption underlying mark-recapture is that all animals have an equal probability of detection, and failure to meet or correct for this assumption-as when certain members of the population are either easier or more difficult to captu...

On topographic mountain maps, cliff drawings are among map elements that are most difficult to produce. However, they belong to some of the most spectacular representations on maps. This paper gives a short historic overview of the development of cliff drawing and describes the most common styles of cliff representations. New techniques are presented in detail for the generation of simplified r...
