Internet Child Abuse: Current Research and Policy provides a timely overview of international policy, legislation and offender management and treatment practice in the area of Internet child abuse. Internet use has grown considerably over the last five years, and information technology now forms a core part of the formal education system in many countries. There is however, increasing evidence that the Internet is used by some adults to access children and young people in order to groom them for the purposes of sexual abuse; as well as to produce and distribute indecent illegal images of children. This book presents and assesses the most recent and current research on internet child abuse, addressing: its nature, the behaviour and treatment of its perpetrators, international policy, legislation and protection, and policing. It will be required reading for an international audience of academics, researchers, policy-makers and criminal justice practitioners with interests in this area.

This paper presents a number of characteristics of the Internet that makes it attractive to online groomers. Relevant Internet characteristics include disconnected personal communication, mediating technology, universality, network externalities, distribution channel, time moderator, lowcost standard, electronic double, electronic double manipulation, information asymmetry, infinite virtual capacity, independence in time and space, cyberspace, and dynamic social network. Potential sex offenders join virtual communities, where they meet other persons who have the same interest. A virtual community provides an online meeting place where people with similar interests can communicate and find useful information. Communication between members may be via email, bulletin boards, online chat, webbased conferencing or other computerbased media.

A prominent research focus, especially in the context of EU public funding, has been the systematic use of the Internet for new ways of value creation in the services sector. This idea of service networks in the Internet, frequently dubbed the Internet of Services or Web service ecosystems, wants to make services tradable in digital media. In order to enable communication and trade between providers and consumers of services, the Internet of Services requires a standard that creates a "commercial envelope" around a service. This is where the Unified Service Description Language (USDL) comes into play as a normative and balanced unification of service information. The unified description established by USDL is machine-processable, considers technical and business aspects of a service as well as functional and non-functional attributes.

On October 4, 2004, Brazil and Argentina requested that WIPO adopt a development-oriented approach to IP and to reconsider its work in relation to developing countries. In October, 2007, WIPO member States adopted a historic decision for the benefit of developing countries, to establish a WIPO Development Agenda. Although there have been several studies related to IP and development that call for IP laws in developing countries to be development-friendly, there is little research that attempts to provide developing countries with practical measures to achieve that goal. This article takes the copyright law in Jordan as a case study and shows how, in practical terms, a pro-development-oriented approach could be implemented in the copyright laws of developing countries. It provides specific recommendations for developing countries to ensure that their IP laws are aligned with and serve their social and economic development objectives.

Distributed Genetic Algorithms (DGAs) designed for the Internet have to take its high communication cost into consideration. For island model GAs, the migration topology has a major impact on DGA performance. This paper describes and evaluates an adaptive migration topology optimizer that keeps the communication load low while maintaining high solution quality. Experiments on benchmark problems show that the optimized topology outperforms static or random topologies of the same degree of connectivity. The applicability of the method on real-world problems is demonstrated on a hard optimization problem in VLSI design.

Despite the potential for e-commerce growth in Latin America, studies investigating factors that influence consumers Internet purchasing behavior are very limited. This research addresses this limitation with a consumer centric study in Chile using the Theory of Reasoned Action. The study examines Chilean consumers beliefs, perceptions of risk, and subjective norms about continued purchasing on the Internet. Findings show that consumers attitude towards purchasing on the Internet is an influential factor on intentions to continue Internet purchasing. Additionally, compatibility and result demonstrability are influential factors on attitudes towards this behavior. The study contributes to the important area of technology post adoption behavior.

The Internet has been shown to positively influence the export activities of firms from developed countries. However, the literature is vague as to whether the Internet has an impact on the export market growth of firms form developing countries. This paper examines of a cross-national sample of 204 firms from a Latin American country (Chile). The results show that Internet marketing activities positively influence information availability and business relationships, which lead to an increase in export market growth. The findings indicate that the Internet influences not only information availability for export performance but also business relationships generally thought to be face to face interactions in nature.
