Divergent trajectories of Arctic change: Implications for future socio-economic patterns.

Climate change is causing rapid warming in the Arctic, which, alongside other physical, socio-economic, cultural, geopolitical, and technological factors, is driving change in the far north. This research presents a conceptual model summarizing Arctic change factors which in turn was used in the design of a Delphi exercise which leveraged a variety of experts to forecast trajectories in different parts of the Arctic. Based on these experts' expectations for economic and governance outcomes by 2050, we find that our results illustrate the "many Arctics" concept or some of the ways in which the Arctic is heterogenous now, and perhaps becoming increasingly so in the future.

Evaluation of the Strength Aptitude Test and Other Fitness Tests to Qualify Air Force Recruits for Physically Demanding Specialties.

The Air Force uses the Strength Aptitude Test (SAT) to determine whether recruits meet the fitness levels needed to perform the duties of various Air Force specialties with physical strength requirements. However, the SAT was developed in the early 1980s and has not been revalidated since then. In the interim, the duties associated with many Air Force Specialty Code classifications may have changed, and new ones have been added.

Evaluating an Operator Physical Fitness Test Prototype for Tactical Air Control Party and Air Liaison Officers: A Preliminary Analysis of Test Implementation.

The U.S. Air Force asked the RAND Corporation to assist its development and validation of gender-neutral tests and standards for battlefield airmen (BA) specialties.

Fit for Duty?: Evaluating the Physical Fitness Requirements of Battlefield Airmen.

Military occupations can be physically demanding, yet few attempts have been made to determine the physical readiness of today's airmen to perform their jobs. Although the Air Force conducts fitness testing of all its airmen, these tests and standards are not based on validated job requirements. As part of a broader Air Force effort to measure the physical readiness of airmen to perform their jobs, this study describes a methodology for establishing physical fitness standards for four physically demanding Air Force occupational specialties-combat controller, pararescue, special operations weather team, and tactical air control party.
