Favoritism: Ethical Dilemmas Viewed Through Multiple Paradigms

Favoritism is a controversial issue in many cultural settings. Related terms include nepotism and cronyism; all three are identified with misconduct in the merit-based business world. The flip side is ethics — the principles of conduct governing an individual or a group (Merriam-Webster, 2012). According to John Dewey (1902), “Ethics is the science that deals with conduct insofar as this is considered to be right or wrong, good or bad.” Since favoritism is perceived as being linked to workplace misconduct, it is necessary to use ethics in examining this issue. The current study applied four lenses of ethics identified by Shapiro and Stefkovich (2011) to help people deal with ethical challenges: justice, critique, care, and the profession. Findings have implications for criteria used to handle ethical challenges in the workplace

Intermediate coherent-phase(PB) states of radiation fields and their nonclassical properties

Intermediate states interpolating coherent states and Pegg-Barnett phase states are investigated using the ladder operator approach. These states reduce to coherent and Pegg-Barnett phase states in two different limits. Statistical and squeezing properties are studied in detail.Comment: 9 pages, 3 EPS figures, use epsf.sty.

The flavour asymmetry of polarized anti-quarks in the nucleon

We present a study of the flavour asymmetry of polarized anti-quarks in the nucleon using the meson cloud model. We include contributions both from the vector mesons and the interference terms of pseudoscalar and vector mesons. Employing the bag model, we first give the polarized valence quark distribution of the $\rho$ meson and the interference distributions. Our calculations show that the interference effect mildly increases the prediction for \Delta \dbar(x)-\Delta \ubar(x) at intermediate $x$ region. We also discuss the contribution of `Pauli blocking' to the asymmetry.Comment: 22 pages, LaTex, 5 PS figures. Version to appear in Eur. Phys. J. C. An appendix is added for expressions for the helicity dependent fluctuation functions. An error in the programme for fluctuation function f_{(\pi\rho)\Delta /N} is corrected, which increases numerical results by about 10%. Unchanged conclusion

Maximal entanglement of nonorthogonal states: classification

A necessary and sufficient condition for the maximal entanglement of bipartite nonorthogonal pure states is found. The condition is applied to the maximal entanglement of coherent states. Some new classes of maximally entangled coherent states are explicited constructed; their limits give rise to maximally entangled Bell-like states.Comment: LaTeX, 8 pages, uses elsart.cl
