Given the importance of IT investments in today’s organization, firms tend to spend increasing amounts of time and resources to better manage IT projects. However these projects continue to have high failure rates thus highlighting the need for improved risk management. A stream of IS research has focused on identifying several causes of managerial risks. The theory base that has been used in t...

Dogs are exceptionally successful at interpreting human pointing gestures to locate food hidden in one of two containers. However, it has repeatedly been questioned whether dogs rely on the pointing gesture or their success is increased by subtle cues from their human handler. In two experiments we used a standard two-way object-choice task to focus on this potential Clever Hans effect. We inve...

In this paper we restructure the idea of ubiquity, seamless and seamful design into a single collaborative framework. We briefly explore the notions of seamlessness, seamfulness and invisibility in connection to the design of ubiquitous system. Additionally, we also briefly explore the connection of the activity theory to the above notions when we deal with user interaction. This leads to the t...

The minus-end directed microtubule motor protein cytoplasmic dynein contributes to many aspects of cell division and it is generally believed that these mitotic functions require the dynein activator and processivity factor, dynactin. New research now shows that dynein accomplishes many of its mitotic functions without dynactin.

We transfer a process algebraic notion of refinement to the B method by using the well-known bridge between the relational semantics underlying the B machines and the labelled transition system semantics of processes. Thus we define delta refinement on Event B systems. We then apply this new refinement to a problem from the literature that previously could only be solved by retrenchment.

improvement suggestions from completed projects and works even in small-and medium-size companies that cannot afford extensive KM investments. However, PMA has been mainly advocated for situations such as completion of large projects, learning from success, or recovering from failure. 2–4 When used appropriately, PMA ensures that team members recognize and remember what they learned during a pr...

The tide against the tobacco industry is growing. The World Health Organisation (WHO) Framework Convention on Tobacco Control (FCTC), a global public health treaty on tobacco control, has been ratifi ed by 174 WHO Member States covering more than 87% of the world’s population.1 At the recently concluded 15th World Conference on Tobacco or Health in Singapore, the Director General (WHO), Dr Marg...

Measuring the polarization of a single photon typically results in its destruction. We propose, demonstrate, and completely characterize a quantum nondemolition (QND) scheme for realizing such a measurement nondestructively. This scheme uses only linear optics and photodetection of ancillary modes to induce a strong nonlinearity at the single-photon level, nondeterministically. We vary this QND...
