A predominant concern in ubiquitous computing (UC) is the natural and effortless interaction of humans with a smart environment in order to carry out a certain task or simply to make life easier. Often, interaction is bootstrapped with a user’s personal, mobile device. Such a device may carry a digital representation in form of a user profile and a key pair that serves as a digital identity. Ex...

Are minorities more vulnerable to opportunism? We find that individuals from a minority group face greater danger of being cheated by an opportunistic firm because trade with the group is less frequent and the value of a reputation for fairness toward the group is correspondingly smaller. If the majority is sufficiently large it can only lose from a solidarity strategy of punishing opportunism ...

In 2001, CDC, the National Institutes of Health, and the Infectious Diseases Society of America convened a working group to develop guidelines for therapy of human immunodeficiency virus (HIV)-associated opportunistic infections to serve as a companion to the Guidelines for Prevention of Opportunistic Infections Among HIV-Infected Persons. In recognition of unique considerations related to HIV ...

Abstract We use inventory write‐downs to differentiate opportunistic and non‐opportunistic overproduction measures. posit that is positively associated with future because generally leads excess inventory, while (to inflate earnings) negatively decrease earnings. find change‐based proxies (deviations from past behaviour) are the likelihood of write‐downs, whereas residual‐based industry norms) ...

In this paper, we address energy savings on a Cloud-based opportunistic infrastructure. The infrastructure implements opportunistic design concepts to provide basic services, such as virtual CPUs, RAM and Disk while profiting from unused capabilities of desktop computer laboratories in a non-intrusive way. We consider the problem of virtual machines consolidation on the opportunistic cloud comp...

Opportunistic network is a type of Delay Tolerant Networks (DTN) where network communication opportunities appear opportunistic, an end-to-end path between source and destination may have never existed, and disconnection and reconnection is common in the network. With numerous emerging opportunistic networking applications, strategies that can enable effective data communication in such challen...

Although consumer opportunistic behavior has drawn attention from managers and scholars for a long time, a special context of two-sided market has been ignored. A multi-stage research program, comprising in depth interviews (Study 1) and three experimental studies (Studies 2, 3, 4), explored opportunistic claiming during service guarantee. The main characteristics of two-sided market (consumer,...

Opportunistic networking is one way to realize pervasive applications while placing little demand on network infrastructure, especially for operating in less well connected environments. In contrast to the ubiquitous network access model inherent to many cloudbased applications, for which the web browser forms the user front end, opportunistic applications require installing software on mobile ...

BACKGROUND Thiopurines are known to cause lymphopenia (<1,500 lymphocytes/μl). As severe lymphopenia (<500C/μl) is associated with opportunistic infections, we investigated severity of thiopurine-related lymphopenia and development of opportunistic infections in our tertiary referral centre. METHODS We retrospectively screened medical records of 1,070 IBD patients and identified 100 individua...
