Download or read book Serial Crime written by Wayne Petherick and published by Academic Press. This book was released on 2009-06-13 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Serial Crime, Second Edition, examines serial predatory behavior and is divided into two main parts. Part one deals with behavioral profiling, and covers a variety of critical issues from the history of profiling and the theoretical schools of thought to its treatment in the mainstream media. This updated edition includes new sections on the problems of induction, metacognition in criminal profiling, and investigative relevance. Part two deals more specifically with a number of types of serial crime including stalking, rape, murder, and arson. Chapters on each of these crimes provide definitions and thresholds, and discussions of the offenders, the crime, and its dynamics. Considerations for behavioral profiling and investigations and the development of new paradigms in each area are interwoven throughout. Topics are conceptually and practically related since profiling has typically seen most application in serial crimes and similar investigations. The unique presentation of the book successfully connects the concepts and creates links to criminal behavior across crimes—murder, sexual assault, and arson—something no other title does. The connection of serial behavior to profiling, the most useful tool in discovering behavior patterns, is also new to the body of literature available and serves to examine the ideal manner in which profiling can be used in conjunction with behavioral science to positively affect criminal investigations. - Provides a theoretical and practical foundation for understanding the motivation and dynamics in a range of serial offenses - Illustrates the promise, purposes and pitfalls of behavioral profiling in the investigation of various serial crimes - Numerous case examples show the real world uses of behavioral profiling in investigations, as well as highlighting a variety of issues in understanding and investigating serial crime

Download or read book Performance analysis of an XForms framework with the main focus on profiling by example of Chiba written by Lars Windauer and published by GRIN Verlag. This book was released on 2008-01-22 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diploma Thesis from the year 2007 in the subject Computer Science - General, grade: 1.0, , language: English, abstract: The goal of this thesis is to analyse a common XForms framework (Chiba) with the focus on profiling for performance inadequacies and to fix them if possible. A prototype of a largely automated performance measurement setup to underpin the analysis and the verification of enhancements has been designed and implemented. The thesis starts with a theoretical part to specify terms & methodologies. Before the paper comes to its practical part the analysed project is introduced. Afterwards a practical performance analysis from the first steps to the narrow of the analysed project is exemplarily described. In detail, chapter 1 Performance & Profiling elaborates how to quantify and profile performance in theory. Chapter 2 Methods introduces various methods to analyse performance. XForms and the analysed product Chiba are presented in chapter 3 XForms / Chiba Fundamentals. The implemented performance analysis is described in chapter 4 Performance Analysis Iteration and chapter 5 Tuning XForms Actions. The Performance Analysis Iteration focuses on the design and implementation of tests to analyse and validate potential performance shortages, while Tuning XForms Actions illustrates how profiling techniques can be utilised not only to analyse but also to enhance a validated shortage. Finally - in chapter 6 Closing - the results of the analysis and the enhancements are reconsidered.
