One of the most widely-implemented service standards provided by the Open Geospatial Consortium (OGC) to the user community is the Web Map Service (WMS). WMS is widely employed globally, but there is limited knowledge of the global distribution, adoption status or the service quality of these online WMS resources. To fill this void, we investigated global WMSs resources and performed distribute...

This paper presents a platform for requests for proposals and describes how ontologies drive the different components: the creation of a proposal, the annotation of vendor data, the transformation of vendor data into other formats and the semantic matching of a proposal against annotated vendor data. The ontology construction started from DOGMA, a methodology with its grounding in the linguisti...

This guide is intended at policy makers willing to embark in a social experimentation in the context of the PROGRESS call for proposals. It is divided in three parts. The first part briefly lays out basic principles to follow in order to design a potentially relevant policy intervention. Those principles are illustrated with an example. The second and third parts present six methods commonly us...

Acquisition of software intensive systems demands significant work on requirements prior to establishing the contract. The acquirer needs to understand the domain, needs, and constraints of the project clearly in order to make realistic size and effort estimates, and to have a solid foundation for defining contract requirements. In this study, an approach for requirements elicitation based on b...

Writing an educational research grant in health profession education is challenging, not only for those doing it for the first time but also for more experienced scholars. The intensity of the competition, the peculiarities of the grant format, the risk of rejection, and the time required are among the many obstacles that can prevent educational researchers with interesting and important ideas ...

In this paper single server homogeneous finite-source retrial queueing systems are investigated. The server is assumed to be subject to random breakdowns depending on whether it is busy or idle. The failure of the server may block or unblock the system’s operations and the service of the interrupted request may be resumed or the call can be transmitted to the orbit. All random variables involve...

It is important for the field of hand surgery to develop a new generation of surgeon-scientists who can produce high-impact studies to raise the profile of this specialty. To this end, organizations such as the American Society for Surgery of the Hand have initiated programs to promote multicenter clinical research that can be competitive for fiscal support from the National Institutes of Healt...

Lewbel (2012) provides an estimator for linear regression models containing an endogenous regressor, when no outside instruments or other such information is available. The method works by exploiting model heteroscedasticity to construct instruments using the available regressors. Some authors have considered the method in empirical applications where an endogenous regressor is binary (e.g., en...

As the type of content available on the web is becoming increasingly diverse, a particular challenge is to properly determine the types of documents sought by a user, that is the domain intent (e.g. image, video) and/or the genre intent (e.g. blog, wikipedia). In this paper, we analysed the Microsoft 2006 RFP click dataset to obtain an understanding of domain and genre intents and their dynamic...
