My right to learn

If books and other media are thought to be connected with terrorism, yet the government does not release a list of such material or inform individuals that they are under suspicion, can students truly feel free to learn, even at a university? Is a free flow of ideas truly possible in a place where only certain ideas are allowed? Is freedom of speech even relevant in a society where expression of certain thoughts or viewpoints is prohibited

Solutions of differential equations with regular coefficients by the methods of Richmond and Runge-Kutta

Numerical solutions of the differential equation which describe the electric field within an inhomogeneous layer of permittivity, upon which a perpendicularly-polarized plane wave is incident, are considered. Richmond's method and the Runge-Kutta method are compared for linear and exponential profiles of permittivities. These two approximate solutions are also compared with the exact solutions

Modified Hilbert transform pair and Kramers-Kronig relations for complex permittivities

Modified versions of the Hilbert transform pair and the Kramers-Kronig relations are derived for the complex permittivity of a plasma/dielectric medium which is singular at the frequency of the applied electric field equal to 0. Such a complex permittivity exists when the plasma/dielectric model allows a loss term but no restoring term. Permittivity, in which both loss and restoring terms are included, is shown to satisfy the standard Hilbert transform pair and, thus, the Kramers-Kronig relations

Angular power spectrums and their relationship to autocorrelation functions of aperture antennas

Normalized angular power spectrum representations have been derived for linear and circular aperture antennas in terms of their autocorrelation functions. Examples of their use are given

Space Shuttle astrodynamical constants

Basic space shuttle astrodynamic constants are reported for use in mission planning and construction of ground and onboard software input loads. The data included here are provided to facilitate the use of consistent numerical values throughout the project

What is Social Justice?

This paper approaches the question What is Social Justice? from the standpoint of a Christian. It discusses the parallels between what Social Justice is and who God is. By understanding this, one better understands how Jesus embodies such ideals and why Christians should too. Thus, Christianity becomes not only about what Social Justice is but who is the God they follow and is He Social Justice minded

Supply market analysis: The moderating effect of social networking on cost reduction

As organizations look for more efficient ways to grow and optimize their supplier network to meet demands, the sourcing process must be streamlined through social networking. Kraljic’s (1983) purchasing portfolio approach argues that different types of purchases need different sourcing strategies. This study extends beyond this strategy by introducing a novel approach of social networking as a mechanism to amplify cost reduction. Through the theoretical underpinning of Transaction Cost Theory, this study builds upon the use of social networking to establish the foundation for future research in this area. In this study, existing and former Purchasing Managers (Sourcing Managers, Procurement Managers, or Buyers), responded to an online survey about their experience with purchasing in the context of three areas: supply market analysis, social networking, and cost reduction. Results revealed that Purchasing Managers use social networking as a strategic sourcing approach to find competitive suppliers. The strategic sourcing approach is identified as supply market analysis, which is the sourcing or supplier research aspect of the 7-step strategic sourcing methodology
