Some efficient exponential estimators in survey sampling: A simulation study

In the framework of sampling theory, a factor-type exponential ratio estimator is proposed for the estimation of the population mean.  The estimator takes into account a spectrum of alpha values (constants) spanning $-1$ to $+1$ when analysing supplementary information for the study variable.  The study demonstrates the effectiveness of the suggested estimators by deriving bias and mean square error equations up to the first degree of large sample approximation.  The analysis shows that the proposed estimators perform better than the existing exponential estimators take

JOURNALISM IMPARTIALITY: HOW TO WRITE ABOUT RELIGIOUS COMMUNITIES

Existing journalistic standards are designed to prevent conflicts within society. In particular, this concerns the standard of balance of opinions, points of view, which implies the need to «give the floor to all parties to the conflict and reflect their positions, while the journalist himself must be as impartial as possible». Specifying of this standard, experts advise to avoid a false balance to consult with professional experts and to refuse altogether from writing material in case of lack of information.
