The ability to sense and respond effectively to fluctuations in an environment is the fundamental problem addressed by cybernetics. When applied to the context of the organizational IT function, agility denotes the capacity of the IT function to perceive "signals" from its internal and external environments, to interpret these, and respond appropriately. The processing of such signals requires the selection and filtering of information to drive decision-making for response in a timely way. The challenge for the IT function is processing an overwhelming collection of signals, in un-standardized formats, and from overlapping sources, that tends to overload decision-makers. Informed by a cybernetic model, we studied how the IT function enables agility. We found evidence (1) that the more mature the policy processes of the IT function, the more the IT function will create agility in information systems; (2) The more mature the intelligence processes of the IT function to look outside the organization, the more the IT function will create agility in information systems and; (3) The more mature the control processes of the IT function that focus on the current use of information systems, the more the IT function will create agility in information systems.

States that control is of the essence in cybernetics. Summarizes the dynamic equations for a flexible one-link manipulator moving in the horizontal plane. Employs the finite element method, based on elementary beam theory, during the process of formulation. Develops and instruments a one-link flexible manipulator in order to control its vibration modes. Uses a simple second-order vibration model which permits vibrations on the rod to be estimated using the hub angle. The validation of the dynamic model and the structural analysis of the flexible manipulator is reached using proper infrared cameras and active light sources for determining actual positions of objects in space. Shows that the performance of the control is satisfactory, even under perturbation action.

In Kazakhstan doctoral students are not expected to make a contribution to knowledge, as is required at Western universities. Rather, their task is to become familiar with what is known and then make policy recommendations for Kazakhstan. For example, how can the human capital in Kazakhstan be improved? This is a very broad subject for a PhD dissertation. However, it does require a holistic perspective, and such dissertation topics may create an opportunity for systems scientists. When Russell Ackoff created the Social Systems Sciences PhD program at the Wharton School of the University of Pennsylvania, he had his students solve practical problems for business or government managers. That program graduated a large number of people who became consultants. A few became academics in several countries. The program created a philosophy and methods for holistic management. Large issues in developing countries may be a source of clients for systems scientists who want to further develop philosophy, theories and methods by working with large social systems.

This paper discusses a framework in which catalog service communities are built, linked for interaction, and constantly monitored and adapted over time. A catalog service community (represented as a peer node in a peer-to-peer network) in our system can be viewed as domain specific data integration mediators representing the domain knowledge and the registry information. The query routing among communities is performed to identify a set of data sources that are relevant to answering a given query. The system monitors the interactions between the communities to discover patterns that may lead to restructuring of the network (e.g., irrelevant peers removed, new relationships created, etc.).
