Discovering and redirecting multimedia services in a personalized manner is achieving increasing importance for mobile users. It is a powerful characteristic, one of the endless capabilities of mobile ecommerce technology. Regardless of their location, users are able to find and utilize services according to their needs and without complex configuration and preknowledge of service interfaces. In addition, they gain control over how, where, and when multimedia services are delivered. Mobile agent platforms may contribute significantly as a supporting component of the overall personalized multimedia service infrastructure. In order to appreciate the impact of MA-based solutions in personalized multimedia service platforms, we present a set of basic criteria related to mobile agents, which may evaluate their necessity and usage. Although it is not an exhaustive list of evaluation criteria, it is sufficient to cover a broad variety of areas under consideration regarding the involvement of mobile agents in service platforms.

Mobile agents gained immense attraction as a new programming concept for implementing distributed applications. However, up to now mobile agent programming has been mainly technology driven, with a focus on the implementation of mobile agent platforms and only small programming applications. In this chapter, we present an extension of the standard UML that provides language concepts for modeling mobility both in analysis and design phases. This extended version of UML is applied to the modeling of an advanced telecommunication system.

Integrity Issue

Mobile agent paradigm is recognized as a new environment for distributed computing and provides many merits such as mobility, security, self-decision, and so on. However, its security problems should be resolved to increase its application to a variety of real domains. Especially, we must guarantee integrity of transferred mobile agents. Although many mobile agent systems were developed, the integrity issue remains a critical one. In this paper, we propose an integrity checking mechanism to do the aforementioned issue. The proposed mechanism is independent of specific security frameworks and can be added and used easily for various mobile agent platforms.

We review mobile agents in the context of distributed object computing and parallel processing. We compare these three paradigms qualitatively. For a quantitative comparison of RMI and Voyager as mobile agent platforms, we identify distributed information processing with flexible load balancing as a convincing application to evaluate the two platforms.

And Control

Technologies and applications that enable multi-party, multimedia communications are becoming more and more pervasive in every facet of daily lives: from distance learning to remote job training, from peer-to-peer conferencing to distributed virtual meetings. To effectively use the evolving Internet infrastructure as ubiquitously accessible platform for the delivery of multi-faceted multimedia services, not only are advances in multimedia communications required but also novel software infrastructures are to be designed to cope with network and end-system heterogeneity, improve management and control of multimedia distributed services, and deliver sustainable QoS levels to end users. In this chapter, the authors propose a holistic approach based on agent-oriented middleware integrating active services, mobile event-driven agents, and multimedia internetworking technology for the component-based prototyping, dynamic deployment, and management of Internet-based real-time multimedia services. The proposed approach is enabled by a distributed software infrastructure (named Mobile Agent Multimedia Space – MAMS) based on event-driven mobile agents and multimedia coordination spaces. In particular, a multimedia coordination space is a component-based architecture consisting of components (players, streamers, transcoders, dumper, forwarders, archivers, GUI adapters, multimedia timers) that provide basic real-time multimedia services. The event-driven mobile agents act as orchestrators of the multimedia space and are capable of migrating across the network to dynamically create and deploy complex media services. The effectiveness and potential of the proposed approach are described through a case study involving the on-demand deployment and management of an adaptive cooperative playback service.

The Impact

Mobile agents may reside in a host or client computer, and can also roam other computers, networks or the Internet to execute their tasks. In this chapter, we will examine the implications of mobility in three aspects: mobile code, mobile hardware and mobile users. The impact of mobility on electronic commerce in the areas of security issues; export controls, legal jurisdiction, taxation and international issues is also analyzed. Mobile agent technologies and mobile computers will play an important role in the new cyberspace economy, however many issues need to be addressed before the technology can be fully implemented.

The Impact

For the Netherlands and Belgium in the twentieth century, occupation is a key concept to understand the impact of the war on welfare state development. The occupation shifted the balance of power between domestic social forces: this was more decisive for welfare state development than the action of the occupier in itself. War and occupation did not result exclusively in more cooperation between social classes: some interest groups saw the war as a window of opportunity to develop strategies resulting in more social conflict. Class cooperation was often part of a political strategy to gain control over social groups or to legitimate social reforms. The world wars changed the scale of organization of social protection, from the local to the national level: after World War II social policy became a mission for the national state. For both countries, war endings had more lasting effects for welfare state development than the occupation itself.

The bullwhip effect is a pervasive phenomenon in all supply chains causing excessive inventory, delivery delays, deterioration of customer service, and high costs. Some researchers have studied this phenomenon from a financial perspective by shedding light on the phenomenon of cash flow bullwhip (CFB). The objective of this article is to provide the state of the art in relation to research work on CFB. Our ambition is not to make an exhaustive list, but to synthesize the main contributions, to enable us to identify other interesting research perspectives. In this regard, certain lines of research remain insufficiently explored, such as the role that supply chain digitization could play in controlling CFB, the impact of CFB on the profitability of companies, or the impacts of the omnichannel commerce on CFB.

The Impact

The coastline of Western Pomerania has natural and cultural assets that have promoted the development of tourism, but also require additional measures to ensure the traditional features and characteristics are protected. This is to ensure that new developments conform to a more uniform set of spatial structures which are in line with the original culture. Today, seaside resorts are characterized by a rapid increase in development with a clear trend towards non-physiognomic architectural forms which continually expand and encroach on land closer to the coastline. This results in a blurring of the original concepts that characterized the founding seaside resort. This study evaluates 11 development projects (including a range of hotels, luxury residential buildings and hotel suites) built in 2009–2020 in the coastal area of Western Pomerania. An assessment of architecture-and-landscape integration for each development project was made, using four groups of evaluation criteria: aesthetic, socio-cultural, functional and locational factors. The study methodology included a historical and interpretative study (iconology, iconography, historiography) and an examination of architecture-and-landscape integration using a pre-prepared evaluation form. Each criterion was first assessed using both field surveys and desk research (including the analysis of construction plans and developer materials), and then compared with the original, traditional qualities of the town. This study demonstrates that it is possible to clearly identify the potential negative impact of tourism development on the cultural landscape of seaside resorts, and provides recommendations for future shaping, management and conservation of the landscape.
