    This report gives an overview of the most relevant organisational and\ud behavioural aspects regarding user profiling. It discusses not only the\ud most important aims of user profiling from both an organisation’s as\ud well as a user’s perspective, it will also discuss organisational motives\ud and barriers for user profiling and the most important conditions for\ud the success of user profiling. Finally recommendations are made and\ud suggestions for further research are given

    Racial Profiling and the War on Terror: Changing Trends and Perspectives

    Minorities in the United States have often been treated unfairly by law enforcement agencies. Prior to the September 11, 2001, terrorist attack on the United States, Blacks were the main victims of racial profiling. Since the terrorist attack, however, Arabs and Muslims are becoming the primary targets for profiling by law enforcement agencies. There are some remarkable similarities between the profiling of Blacks and the profiling of Arabs and Muslims. In both cases, the fundamental problems with racial profiling are that it violates the civil liberties of innocent people and denies minorities the equal protection of the law. The War on Terror has redefined racial profiling. It has not only led to a shift in the target population, but it has also changed the ways in which racial profiling is conducted

    MAP: Microblogging Assisted Profiling of TV Shows

    Online microblogging services that have been increasingly used by people to share and exchange information, have emerged as a promising way to profiling multimedia contents, in a sense to provide users a socialized abstraction and understanding of these contents. In this paper, we propose a microblogging profiling framework, to provide a social demonstration of TV shows. Challenges for this study lie in two folds: First, TV shows are generally offline, i.e., most of them are not originally from the Internet, and we need to create a connection between these TV shows with online microblogging services; Second, contents in a microblogging service are extremely noisy for video profiling, and we need to strategically retrieve the most related information for the TV show profiling.To address these challenges, we propose a MAP, a microblogging-assisted profiling framework, with contributions as follows: i) We propose a joint user and content retrieval scheme, which uses information about both actors and topics of a TV show to retrieve related microblogs; ii) We propose a social-aware profiling strategy, which profiles a video according to not only its content, but also the social relationship of its microblogging users and its propagation in the social network; iii) We present some interesting analysis, based on our framework to profile real-world TV shows

    Slanted hole array beam profiler (SHArP)—a high-resolution portable beam profiler based on a linear aperture array

    We demonstrate a novel high-resolution portable beam profiler based on a slanted linear array of small apertures, termed a slanted hole array beam profiler (SHArP). The apertures are directly fabricated on a metal-coated CMOS imaging sensor. With a single linear scan, the aperture array can establish a virtual grid of sampling points for beam profiling. With our prototype, we demonstrate beam profiling of Gaussian beams over an area of 66.5 μm×66.5 μm with a resolution of 0.8 μm (compare with the CMOS pixel size of 10 μm). The resolution can be improved into the range of submicrometers by fabricating smaller apertures. The good correspondence between the measured and calculated beam profiles proves the fidelity of our new beam profiling scheme
