In this introductory chapter, the author begins by looking at the Internet from an historical and communication perspective in an effort to understand its significance in the contemporary world. Then he gives an overview of the most searched topics on the Internet and identifies prospects that have opened up and perils that lurk in the information highways of our Internet age. He concludes with a brief overview of the chapters in this volume of studies. [For the complete volume, "The Internet and the Google Age: Prospects and Perils," see ED576666.]

In this chapter, the author provides an overview of how the Internet, a byproduct of our times, is shaping our culture and society in profound ways. He notes some of the major concerns and perils of the Internet age and concludes by pointing out how and why certain countries are targeting the Internet in terms of increased regulation and surveillance.

When a model may be fitted separately to each individual statistical unit, inspection of the point estimates may help the statistician to understand between-individual variability and to identify possible relationships. However, some information will be lost in such an approach because estimation uncertainty is disregarded. We present a comparative method for exploratory repeated-measures analysis to complement the point estimates that was motivated by and is demonstrated by analysis of data from the CADET II breast-cancer screening study. The approach helped to flag up some unusual reader behavior, to assess differences in performance, and to identify potential random-effects models for further analysis., Comment: Published in at http://dx.doi.org/10.1214/11-AOAS481 the Annals of Applied Statistics (http://www.imstat.org/aoas/) by the Institute of Mathematical Statistics (http://www.imstat.org)

A wheel assembly for an electric vehicle includes a wheel rim that is concentrically disposed about a central axis. A propulsion-braking module is disposed within an interior region of the wheel rim. The propulsion-braking module rotatably supports the wheel rim for rotation about the central axis. The propulsion-braking module includes a liquid cooled electric motor having a rotor rotatable about the central axis, and a stator disposed radially inside the rotor relative to the central axis. A motor-wheel interface hub is fixedly attached to the wheel rim, and is directly attached to the rotor for rotation with the rotor. The motor-wheel interface hub directly transmits torque from the electric motor to the wheel rim at a 1:1 ratio. The propulsion-braking module includes a drum brake system having an electric motor that rotates a cam device, which actuates the brake shoes.
