Police Academy Training: An Evaluation of the Strengths and Weaknesses of Police Academies

The purpose of this paper is to give an overview of the historical and current protocols which have existed in police academies, with a focus on the gender issues being faced by female police officers. The development of the police force is examined, with explanation of the differences and developments aligning with each era of history. Next, current police practices are elaborated upon, emphasizing the difficulties women experience in becoming police officers and where the ideologies of the police academies originated. Finally, suggestions are given based on research findings in order to reduce the ideological divides that occur in the police force and increase the effectiveness of officers’ work in the community

Integrable properties of sigma-models with non-symmetric target spaces

It is well-known that sigma-models with symmetric target spaces are classically integrable. At the example of the model with target space the flag manifold U(3)/U(1)^3 -- a non-symmetric space -- we show that the introduction of torsion allows to cast the equations of motion in the form of a zero-curvature condition for a one-parametric family of connections, which can be a sign of integrability of the theory. We also elaborate on geometric aspects of the proposed model.Comment: 8 pages, 1 figur

Classical solutions of a flag manifold sigma-model

We study a sigma-model with target space the flag manifold U(3)/U(1)^3. A peculiarity of the model is that the complex structure on the target space enters explicitly in the action. We describe the classical solutions of the model for the case when the worldsheet is a sphere CP^1.Comment: 11 pages, 2 figure

Complex structures and zero-curvature equations for sigma-models

We construct zero-curvature representations for the equations of motion of a class of sigma-models with complex homogeneous target spaces, not necessarily symmetric. We show that in the symmetric case the proposed flat connection is gauge-equivalent to the conventional one.Comment: 8 page

The worldsheet low-energy limit of the AdS_4 x CP^3 superstring

We consider the AdS_4 x CP^3 IIA superstring sigma-model in the background of the "spinning string" classical solution, which possesses two Noether spins. In the limit when one of the spins is infinite there are massless excitations, which govern the infrared worldsheet properties of the model. We obtain a sigma-model of CP^3 with fermions, which describes the dynamics of these massless modes.Comment: 41 page

Directing transport by polarized radiation in presence of chaos and dissipation

We study numerically the dynamics of particles on the Galton board of semi-disk scatters in presence of monochromatic radiation and dissipation. It is shown that under certain conditions the radiation leads to appearance of directed transport linked to an underlining strange attractor. The direction of transport can be efficiently changed by radiation polarization. The experimental realization of this effect in asymmetric antidot superlattices is discussed.Comment: revtex, 4 pages, 6 fig
