A Descriptive Study of Information Operations and Information Warfare Awareness in the United States Air Force

Information has always been important in military affairs, conflicts, and wars. Information warfare is an important new concept that is emphasized by the significance of computer and information technology. The United States Air Force has educated and trained individuals in information warfare since recognizing the importance of information warfare in 1995. The Air Force Information Warfare Center and the information warfare squadron were also created to address information warfare concerns. Information warfare is important to the entire Air Force. How familiar are Air Force people generally in information warfare? This thesis addresses awareness of information warfare and information operations concepts. Despite the amount of focus, training, and education, it was unknown how aware individuals were concerning information warfare and information operations. This thesis surveyed eight hundred officers and enlisted personnel with a response rate of 214 to determine the baseline of information warfare awareness. Approximately sixty percent of the respondents indicated that they were aware of information warfare. Also, individuals who received information warfare training responded higher than individuals without training. This is the first study in information warfare and information operations awareness. Additional research is needed to determine how the awareness levels are changing and the effectiveness of the training

Generation of Large-Scale Vorticity in a Homogeneous Turbulence with a Mean Velocity Shear

An effect of a mean velocity shear on a turbulence and on the effective force which is determined by the gradient of Reynolds stresses is studied. Generation of a mean vorticity in a homogeneous incompressible turbulent flow with an imposed mean velocity shear due to an excitation of a large-scale instability is found. The instability is caused by a combined effect of the large-scale shear motions (''skew-induced" deflection of equilibrium mean vorticity) and ''Reynolds stress-induced" generation of perturbations of mean vorticity. Spatial characteristics, such as the minimum size of the growing perturbations and the size of perturbations with the maximum growth rate, are determined. This instability and the dynamics of the mean vorticity are associated with the Prandtl's turbulent secondary flows. This instability is similar to the mean-field magnetic dynamo instability. Astrophysical applications of the obtained results are discussed.Comment: 8 pages, 3 figures, REVTEX4, submitted to Phys. Rev.
