Information and Communication Technology as a Differentiation Tool in Restaurants
2014
Hospitality companies implement various communication and information technologies to improve efficiency and customer service, among other aspects. However, the literature has paid little attention to investment in technology by restaurants. Therefore, this article aims at testing the use of technology as a differentiation instrument by restaurants. As a result of this analysis for a sample of 150 restaurant owners or managers, these findings allow the identification of the specific technology solutions that make the difference across restaurants and, thus, to infer the information and communication technologies that should be prioritized by restaurant owners/managers depending on their res…
Comparison of Attention Behaviour Across User Sets through Automatic Identification of Common Areas of Interest
2020
Eye tracking is used to analyze and compare user behaviour within numerous domains, but long duration eye tracking experiments across multiple users generate millions of eye gaze samples, making th ...
Interaction affordances in traditional instruments and tablet computers: A study of children’s musical group creativity
2019
In order to promote children’s collaborative musical creativity in new digital environments, we need a better understanding not only of the sound production capabilities provided by the new digital tools, but also of the interaction affordances involved. This study focuses on the interactional patterns emerging in children’s musical creativity, comparing creative group processes on iPad tablet computers (with GarageBand software) to processes on traditional musical instruments. Both instrumentations were assigned to five groups of four 10–12-year-olds for creating sound landscapes for a “space” movie. The traditional instrument groups’ processes were characterized by peer teaching as well …

Devenir des enfants issus des techniques d’assistance médicale à la procréation
2013
Since the birth of the first baby conceived by in vitro fertilization (IVF) 30 years ago (Louise Brown in 1978), there has been a rapid and constant increase in the number of couples using assisted reproductive technologies (ART). Around four million of children have been born from couples experiencing fertility problems, through the use of ART, comprising roughly 2-3 % of all births in Europe and U.S. That highlights that these modes of fertilization are now well assumed by our societies. However, several questions on health of these children remain to be elucidated. As evoked in this review, even if methodological limitations exist, numerous studies have reported increased risks of birth …

Behavior-based personalization in web search
2016
Personalized search approaches tailor search results to users' current interests, so as to help improve the likelihood of a user finding relevant documents for their query. Previous work on personalized search focuses on using the content of the user's query and of the documents clicked to model the user's preference. In this paper we focus on a different type of signal: We investigate the use of behavioral information for the purpose of search personalization. That is, we consider clicks and dwell time for reranking an initially retrieved list of documents. In particular, we (i) investigate the impact of distributions of users and queries on document reranking; (ii) estimate the relevance …
Errors and Complications in SQL Query Formulation
2018
SQL is taught in almost all university level database courses, yet SQL has received relatively little attention in educational research. In this study, we present a database management system independent categorization of SQL query errors that students make in an introductory database course. We base the categorization on previous literature, present a class of logical errors that has not been studied in detail, and review and complement these findings by analyzing over 33,000 SQL queries submitted by students. Our analysis verifies error findings presented in previous literature and reveals new types of errors, namely logical errors recurring in similar manners among different students. We…
Schema-Based Visual Queries over Linked Data Endpoints
2019
We present the option to use the schema-based visual query tool ViziQuer over realistic Linked Data endpoints. We describe the tool meta-schema structure and the means for the endpoint schema retrieval both from an OWL ontology and from a SPARQL endpoint. We report on a store of the endpoint-specific schemas and the options to support the schema presentation to the end-user both as a class tree within the environment and as external visual diagram.
Semantic Portal for Legislative Information
2006
Semantic portals enabled by Semantic Web technologies have been suggested to provide a point of access to an integrated body of information about some domain. In the area of e-Government there are multiple possible domains for semantic portals, one of them being legislative work. In this paper we propose a semantic portal based on a rich metadata repository to support the retrieval of legislative information. The portal provides process oriented semantic browsing capabilities. A prototype of the portal has been implemented for the retrieval of Finnish legislative information.
