This paper aims at explaining how intermediaries influence collaborative innovation projects, suggesting a conceptual-theoretical framework about intermediaries’ roles and practices. The qualitative research was developed through the case study of the Orange Service Call and Reward project performed by the National Endowment for Science, Technology and the Arts (NESTA) for Orange Labs, the R&D ...

Electronic Assessment systems usually provide an authoring tool for creating activities (mainly closed-type questions) and administering the flow of their presentation and are also complemented with a delivery environment for learners. In this paper, we discuss learner’s control over authored assessment. The prototype application, ReACTS (Re-Adaptable Computerized Testing System), enables learn...

In this paper, we address the issues of maintaining sensing coverage and connectivity by keeping a minimum number of sensor nodes in the active mode in wireless sensor networks. We investigate the relationship between coverage and connectivity by solving the following two sub-problems. First, we prove that if the radio range is at least twice the sensing range, complete coverage of a convex are...

Excessive gaming among emerging adults is a growing concern, especially in cases where it interferes with key developmental milestones such as gaining an education or establishing a career. Although researchers have begun to understand the effects of excessive gaming on young people themselves, we know remarkably little about how emerging adults' gaming may affect family relationships. Utilizin...

OBJECTIVES Klotho-deficient mice develop a syndrome resembling accelerated ageing, and genetic variants of Klotho have been associated with human ageing. In humans, serum levels of soluble Klotho decrease with age and with chronic renal failure. The aim of our study was to examine the relationship between excess growth hormone (GH) and serum levels of Klotho in patients with acromegaly, a disea...

This article aims to identify how knowledge workers develop their own collaboration strategies and techniques for getting their work done in complex, dynamic knowledge intensive work environments. Three case studies have been conducted to explore the nature of routines in different collaborative working settings as they provide sufficient detail to better understand the actual state and problem...

This paper presents FrameNet’s approach to the representation of Support Verbs, as but one type of multiword expression (MWE) included in the database. In addition to motivating and illustrating FrameNet’s newly consistent annotation practice for Support Verb constructions, the present work advocates adopting a broad view of what constitutes a multiword expression.

OBJECTIVE To define the distribution of Pediatric Surgeons in Brazil and the distribution of job offered for specialists in the country. To compare the professional profile of Brazilian Pediatric Surgeons with other countries. METHODS Statistical data derived from Brazilian Institute of Geography and Statistics (IBGE), Brazilian Medical Council (CFM) and Brazilian Society of Pediatric Surgery...

A particularly simple Markov chain model for a reference string is described. The model, which is only slightly more complicated than the independent reference model, generates strings that have a locality property and that have a specified probability distribution of references over pages. Expressions are obtained for expected working-set size and expected working-set miss ratio. The of change...
