I use titlesec to capitalize and display the chapter title at the center. Everything is fine until I get to the bibliography, the word 'bibliography' is not capitalized. Here is an example
\documentclass[a4paper, 12pt]{report}
\usepackage{cite}
\usepackage{titlesec}
\titlespacing*{\chapter}{0pt}{1in}{20pt}
\titleformat{\chapter}[display]
{\centering\normalfont\normalsize}{\MakeUppercase{\chaptertitlename} \thechapter}{0pt}{\small}
\titleformat{\section}
{\normalfont\normalsize\bfseries}{\thesection}{1em}{}
\titleformat{\subsection}
{\normalfont\normalsize\bfseries}{\thesubsection}{1em}{}
\titleformat{\subsubsection}
{\normalfont\normalsize\bfseries}{\thesubsubsection}{1em}{}
\begin{document}
\chapter{Chapter 1}
This is a workingn example
\begin{thebibliography}{100}
\bibitem{Niesen}
Niesen, Social networks/blogs now account for one in every four and a half
minutes online,
http://blog.nielsen.com/nielsenwire/global/social-media-accounts-for-22-perc%
ent-of-time-online/, report (June 2010).
\bibitem{AirwideSolutions}

\end{document}
