A critical review of psychological instruments used in police officer selection

Purpose
The purpose of this paper is to critically examine the instruments used in the screening process, with particular attention given to supporting research validation. Psychological screening is a well-established process used in the selection of employees across public safety industries, particularly in police settings. Screening in and screening out are both possible, with screening out being the most commonly used method. Little attention, however, has been given to evaluating the comparative validities of the instruments used.

Design/methodology/approach
This review investigates literature supporting the use of the Minnesota Multiphasic Personality Inventory (MMPI), the California Personality Inventory (CPI), the Inwald Personality Inventory (IPI), the Australian Institute of Forensic Psychology's test battery (AIFP), and some other less researched tests. Research supporting the validity of each test is discussed.

Findings
It was found that no test possesses unequivocal research support, although the CPI and AIFP tests show promise. Most formal research into the validity of the instruments lacks appropriate experimental structure and is therefore less powerful as “evidence” of the utility of the instrument(s).

Practical implications
This research raises the notion that many current screening practices are likely to be adding minimal value to the selection process by way of using instruments that are not “cut out” for the job. This has implications for policy and practice at the recruitment stage of police employment.

Originality/value
This research provides a critical overview of the instruments and their validity studies rather than examining the general process of psychological screening. As such, it is useful to those working in selection who are facing the choice of psychological instrument. Possibilities for future research are presented, and development opportunities for a best practice instrument are discussed.

Advanced science and technology letters : advanced researches on security and assurance

We would like to welcome you to the Regular Papers proceedings of the 7th International Conference on Information Security and Assurance (ISA 2013) which was held on April 26-28, 2013 at Waterfront Airport Hotel and Casino, Cebu, Philippines. ISA 2013 is focused on various aspects of advances in researches on Security and Assurance. It provided a chance for academic and industry professionals to discuss recent progress in the related areas. We expect that the conference and its publications will be a trigger for further related research and technology improvements in this important subject. We would like to acknowledge the great effort of all the Chairs and members of the Editorial Committee. We would like to express our gratitude to all of the authors of submitted papers and to all attendees, for their contributions and participation. We believe in the need for continuing this undertaking in the future.

Ubiquitous multicore (UM) methodology for multimedia

For more than a decade now, multimedia developers have usually "ride the waves", so to speak, with the coming of each generation of microprocessors, which allows their applications, designs and programs to usually running more proficiently, efficiently and effectively. This so-called "free" ride seems to be coming to an end, with results of increases clock speeds, the widening of the gap in processor and memory performance, and the tradeoffs that are needed to meet the former two points, with the new multi-core systems. In this paper, we build upon our previous work within multi-core systems, by proposing a ubiquitous multi-core (UM) design. The goal of such a framework is help researchers to plan and implement their multimedia applications so they can take advantage of speed up computations of multi-core systems and allow real-time multimedia. As our experiments show, our UM system increases performance speeds at an average of 100%, with the average execution cost of 1.4ms, showing that multimedia can use multi-core resources efficiently and effectively.
