The strategic importance of building highly capable information technology (IT) infrastructure has become a crucial management issue of the 1990s and beyond. However, in spite of the numerous benefits attributed to IT infrastructure, these claims remain unsubstantiated. This problem is due, in part, to inadequate conceptualizations of IT infrastructure and its measurement as well as a lack of t...

Supervisory control is the main means to assure a high level performance and availability of large IT infrastructures. Applied control theory is used in physical and virtualization based clustering, autonomic-, self-healing and cloud computing, but similar problems arise in any distributed environment. The selection of a compact, but sufficiently characteristic set of control variables is one o...

Algorithmic trading has becomes a huge proportion of the trades executed on securities exchanges around the world. Reduced transaction costs have faciliated a new generation of trading strategies which depend on computing and network speed. Algorithmic trading also poses a new set of risks and challenges regulators to keep up. This paper reviews the technology infrastructre supporting algorithm...

Appropriate information technology (IT) infrastructure capability is critically needed for organizations when seeking effective adaptation to a dynamic market. This adaptation can be treated as a type of management of innovation in terms of Miles and Snow’s typology. Although many studies have explored IT infrastructure capability, it is still unclear how that capability can be diverse among in...

Investment in information technology (IT) infrastructure has in recent years become a strategic organizational choice. Yet, there exists little understanding of the organizational factors that determine IT infrastructure capabilities and investment requirements. Using a filed survey of both business and IT executives, this study tests a research model that links a set of organizational factors ...

The IT infrastructure in organizations today is an outgrowth of over 50 years of evolution in computing platforms. We have identified five stages in this evolution, each representing a different configuration of computing power and infrastructure elements (see Figure 4-1). The five eras are automated special-purpose machines, general-purpose mainframe and minicomputer computing, personal comput...

The form in which knowledge is described and encapsulated has a major impact on the design of libraries and the functions performed within the library. Libraries as we known them have been primarily built to store and disseminate knowledge in book format. New technology and the changing needs of knowledge workers, which form important parts of the logocentric, practicentric, and democentric ele...

Critical infrastructures are falsely believed to be safe when they are isolated from the Internet. However, the recent appearance of Stuxnet demonstrated that isolated networks are no longer safe. We observe that a better intrusion detection scheme can be established based on the unique features of critical infrastructures. In this paper, we propose a whitelist-based detection system. Network a...

Every user at TIK [4] that has its own PC-compatible standing under his desk and needs to work with a real Operating System like any flavour of Unix, i.e. Linux [8], *BSD [7, 18, 17, 1], Solaris [21]. Thus, users of other OS may get an idea of what they could profite when using UNIX-style OS. However, they get to know what they need for their networking/eMailing systems. Please get to know, thi...
