An EUD Approach for Making MBUI Practical

Proceedings of the First International Workshop on Making model-based user interface design practical: usable and open methods and tools. Funchal, Madeira, Portugal, January.13, 2004Also published online by CEUR Workshop Proceedings (CEUR-WS.org, ISSN 1613-0073)In this paper, we present our perspective on Model-Based User Interfaces (hereafter MBUI) paradigm and provide with our experience in this area combining high-level knowledge-based data models (i.e. ontologies) and reverse engineering processes to carry through a pragmatic MBUI vision. Our approach is based on using End-User Development (hereafter EUD) techniques (i.e. Programming by Example) to enable the user to carry out editing tasks in a MBUI environment. This advocates an EUD-for-MBUI approach, where the system avoids the user from having to deal with interface specification languages.The work reported in this paper is being supported by the Spanish Ministry of Science and Technology (MCyT), project number TIC2002-194

Diseño interactivo de cursos adaptativos

Versión electrónica de la ponencia presentada en el Simposio Internacional de Informática Educativa (SIIE 2000), celebrado en 2000 en Puertollano, CáceresLa capacidad de las aplicaciones educativas para adaptarse al estudiante es una cualidad perseguida desde hace tiempo en el campo de la enseñanza asistida por ordenador. La dificultad que entraña la elaboración de este tipo de productos, y la ausencia de herramientas adecuadas que faciliten esta labor, obstaculizan la participación de instructores y docentes en la elaboración del material. En este artículo presentamos una herramienta de autor, ATLAS, cuyo objetivo es conciliar potencia y facilidad de uso en el diseño de cursos web adaptativos. ATLAS permite la construcción totalmente interactiva de cursos que se adaptan automáticamente a las características del alumno y su comportamiento durante la realización del curso. El diseñador interactua con la herramienta mediante un lenguaje visual intuitivo basado en la manipulación directa de los elementos implicados en el curso, de forma que la herramienta realiza la transición entre la forma de entender el curso por parte de un profesor, y el modelo de representación del sistema subyacente

They pay poor attention to users who have no programming abilities but need to customize software applications. At some point, such needs force end-users to act as designers in various aspects of software authoring and development. Every day, more new computing-related professionals attempt to create and modify existing applications in order to customize web-based artifacts that will help them carry out their daily tasks. In general they are domain experts rather than skilled software designers, and new authoring mechanisms are needed in order that they can accomplish their tasks properly. The work we present is an effort to supply end-users with easy mechanisms for authoring web-based applications. To complement this effort, we present a user study showing that it is possible to carry out a trade-off between expressiveness and ease of use in order to provide end-users with authoring facilities.The work reported in this paper is being partially supported by the Spanish Ministry of Science and Technology (MCyT), projects TIN2005-06885 and TSI2005-08225-C07-06

Semantic monitoring techniques for EUD

This is an electronic version of the paper presented at the Workshop on End User Modeling at the ACM International Conference on Human Factors in Computing Systems (CHI 2003), held in Florida on 2003In this work, we present how domain modeling and Programming by Example techniques can be combined to carry through a EUD approach. Our techniques are based on detecting iteration patterns from user monitoring as well as extracting knowledge about the user interface itself. Combining those, dynamic behavior can be characterized, getting maximum amount of semantic at each user step. This approach can be used in order to make PBE inference process more effective as well as to result in enhancing PBE global efficiency.The work reported in this paper is being supported by the Spanish Ministry of Science and Technology (MCyT), project number TIC2002-1948

Ca impurity in small mixed 4^4He-3^3He clusters

The structure of small mixed helium clusters doped with one calcium atom has been determined within the diffusion Monte Carlo framework. The results show that the calcium atom sits at the $^4$He-$^3$He interface. This is in agreement with previous studies, both experimental and theoretical, performed for large clusters. A comparison between the results obtained for the largest cluster we have considered for each isotope shows a clear tendency of the Ca atom to reside in a deep dimple at the surface of the cluster for $^4$He clusters, and to become fully solvated for $^3$He clusters. We have calculated the absorption spectrum of Ca around the $4s4p \leftarrow 4s^2$ transition and have found that it is blue-shifted from that of the free-atom transition by an amount that depends on the size and composition of the cluster.Comment: 24 pages, 11 figures.

mRNA COVID-19 vaccine is well tolerated in patients with cutaneous and systemic mastocytosis with mast cell activation symptoms and anaphylaxis

Mastocytosis encompasses a heterogeneous group of diseases characterized by the presence of clonal mast cells (MCs) in tissues and symptoms of MC activation, including anaphylaxis.1 Vaccination has been shown to cause exacerbation of MC mediator-related symptoms.2 Vaccines against coronavirus disease 2019 (COVID-19) are the solution to the current pandemic, but reports of anaphylaxis following vaccination with the BNT162b2 Pfizer-BioNTech mRNA vaccine have emerged.3 As such, it is important to provide evidence of the safety of mRNA vaccines in populations at risk for anaphylaxis, including patients with mastocytosis and MC activation symptoms

Information and Communication Technology (ICT) and International Business Travel: Mobility Allies?

Like forecasts about the paperless office, technological solutions to the problem of international business travel continue to be deferred. As with the increased use of office paper, international business travel is defying predictions of its decline. There is growing evidence to suggest that business sectors which seem ideally placed to substitute information and communication technology (ICT) for travel, are actually generating more physical travel than other sectors. This paper develops a case study of the Irish software industry to exemplify why international travel is not diminishing in importance how and the ICT and business travel relationship is changing in this sector. The paper presents research findings that suggest that a cycle of substitution, generation and modification relationships have occurred as mobility interdependencies have developed.Peer Reviewe

Neighbor Selection and Weighting in User-Based Collaborative Filtering: A Performance Prediction Approach

This is the author's version of the work. It is posted here for your personal use. Not for redistribution. The definitive Version of Record was published in ACM Transactions on the Web, http://dx.doi.org/10.1145/2579993User-based collaborative filtering systems suggest interesting items to a user relying on similar-minded people called neighbors. The selection and weighting of these neighbors characterize the different recommendation approaches. While standard strategies perform a neighbor selection based on user similarities, trust-aware recommendation algorithms rely on other aspects indicative of user trust and reliability. In this article we restate the trust-aware recommendation problem, generalizing it in terms of performance prediction techniques, whose goal is to predict the performance of an information retrieval system in response to a particular query. We investigate how to adopt the preceding generalization to define a unified framework where we conduct an objective analysis of the effectiveness (predictive power) of neighbor scoring functions. The proposed framework enables discriminating whether recommendation performance improvements are caused by the used neighbor scoring functions or by the ways these functions are used in the recommendation computation. We evaluated our approach with several state-of-the-art and novel neighbor scoring functions on three publicly available datasets. By empirically comparing four neighbor quality metrics and thirteen performance predictors, we found strong predictive power for some of the predictors with respect to certain metrics. This result was then validated by checking the final performance of recommendation strategies where predictors are used for selecting and/or weighting user neighbors. As a result, we have found that, by measuring the predictive power of neighbor performance predictors, we are able to anticipate which predictors are going to perform better in neighbor-scoring-powered versions of a user-based collaborative filtering algorithm.This research was supported by the Spanish Ministry of Science and Research (TIN2011-28538-C02-01).

Assessing the magnitude and direction of asymmetry in unilateral jump and change of direction speed tasks in youth female team-sport athletes

The direction of inter-limb asymmetries and the change of direction (COD) deficit are two aspects that have increased in recent years. The main objective of the present study was to assess the magnitude of neuromuscular asymmetries in an elite youth female team-sports sample and determine its directionality. Secondary objectives were to evaluate the relationship between COD deficit, linear speed and COD time performance. Elite female youth basketball and handball players (n = 33, age = 16 ± 1.17 y) performed the Single Leg Countermovement Jump in vertical (SLCJ-V), horizontal (SLCJ-H), and lateral (SLCJ-L) directions, the COD and the 10-m sprint. Results showed statistical differences between limbs in all the neuromuscular tests (p < 0.001). The Kappa coefficient showed poor to fair levels of agreement between tasks (K range = -0.087 to 0.233), indicating that asymmetries rarely favoured the same limb between skills. Additionally, small and non-significant correlations were found between the linear sprint capacity and the COD ability. The findings of the present study highlight the independent directionality of asymmetries across tests. The COD deficit does not appear to be much more advantageous than COD total time to measure asymmetry. Practitioners are encouraged to use a fitness testing battery to detect existing side differences and each ability should be specifically trained with functional tasks
