This paper addresses the issue of defining a location service suitable for very dynamic and highly populated networks (millions of users), where services might experience highly correlated peaks of traffic or synchronized access to specific servers. Mobile agent technology is flexible enough to solve the major problems, allowing the dynamic deployment of new application servers when needed. But...

When a client interacts with an expert, e.g. a doctor, it falls upon the expert to ask questions that steer the process towards fulfilling the client’s needs. This is most efficient given that the expert has more knowledge and a broader view of possible illnesses and treatments. On the other hand, when faced with an information retrieval (IR) task, most IR systems leave to the client the task o...

Interactive access control allows a server to compute on the fly missing credentials needed to grant access and to adapt its responses on the basis of client’s presented and declined credentials. Yet, it may disclose too much information on what credentials a client needs. Automated trust negotiation allows for a controlled disclosure on what credentials a client has during a mutual disclosure ...

This paper describes a study that explored the extent and nature of workplace violence in child protective services (CPS). A total of 68 workers and clients reported on their experiences. Of workers, 70% reported being the victim of client violence, and 22% reported they had perpetrated a violent act toward a client. Of clients, 55% reported being a victim of assault by a CPS worker, while 42% ...

This paper investigates the integration of ontology storage and ontology-based applications through the example of the EnerSearch case study conducted within the On-To-Knowledge research project. We look at the problem of integrating the Sesame storage and query facility with its client application and identify both functional and technical needs for a new software package for client-side query...

This paper presents a technique which detects all behavioural incompatibilities between two service interfaces (a client and a provider). This may happen because the provider has evolved and its interface has been modified. It may also happen because the client decided to change for another provider which addresses the same needs but offers a different interface. Unlike prior work, the proposed...

Based on a case study of a Portuguese packaging firm, this paper examines how vertical integration of the supplier serves as a vehicle for the full outsourcing of the client firms' needs in a solution that reduces transaction costs, favors specialization, and permits small and medium-sized firms to develop competencies that may be exploited in a wide array of projects. Vertical integration by t...

Community based organizations (CBOs) play a frontline role in HIV/AIDS prevention activities. CBOs face formidable challenges to effective delivery of HIV prevention services including client characteristics such as homelessness and CBO characteristics such as limited resources and staff turnover. Despite these obstacles, CBOs are generally well positioned to deliver services to specific high-r...

increased services, increased attention to unmet needs, and greater cost-effectiveness. Studies in Guatemala and Mexico showed that client screening resulted in greater information given to clients as well as important improvements in the use of services (Vernon and Foreit 1999). In a study in Peru, the screening intervention increased the number of services provided per client visit by 13 perc...
