2 Librarians Do Fly : Strategies for Staying Aloft

Purpose: To examine past and future predictions about academic libraries and identify the skills that librarians will need to survive in an increasingly digital environment. Methodology/approach: A review of relevant literature, including ephemeral material such as job advertisements, indicates a broad consensus about the skills required. The lifecycle of an academic librarian is considered fro...

Synoptic Determination and Forecasting Significance of Cold Fronts Aloft

Arachnid aloft: directed aerial descent in neotropical canopy spiders.

The behaviour of directed aerial descent has been described for numerous taxa of wingless hexapods as they fall from the tropical rainforest canopy, but is not known in other terrestrial arthropods. Here, we describe similar controlled aerial behaviours for large arboreal spiders in the genus Selenops (Selenopidae). We dropped 59 such spiders from either canopy platforms or tree crowns in Panam...

Using Aircraft Radar Tracks to Estimate Winds Aloft

In air traffic control, the wind is a critical factor because it affects, among other important variables, the amount of time an aircraft will take to reach its destination. The authors have developed a method for estimating winds aloft in which the radar tracks of aircraft are used; i.e., data beyond what are already available to terminal air traffic control are not required. The method, which...
