Viabilidad de la informatización del examen lengua extranjera de las Pruebas de Acceso a la Universidad
2016
[ES] Tras el anuncio por parte del Gobierno de la inclusión de una sección oral en el examen de lengua extranjera de la Prueba de Acceso a la Universidad, que estaba prevista para 2012, diferentes posibilidades en cuanto a la informatización de dicha sección se analizaron en un esfuerzo por encontrar una propuesta viable para la evaluación de las destrezas orales y un estudio cualitativo se llevó a cabo con 286 participantes. Los resultados arrojaron luz en cuanto a la recepción inicial de las soluciones tecnológicas desarrolladas dentro de un sistema de gestión del aprendizaje y en cuanto a la viabilidad de la informatización de la sección oral de la prueba, mostrando que es posible implan…
Programming languages for data-Intensive HPC applications: A systematic mapping study
2020
This work is a result of activities from COST Action 10406 High -Performance Modelling and Simulation for Big Data Applications (cHiPSet), funded by the European Cooperation in Science and Technology. FCT, Portugal for grants: NOVA LINCS Research Laboratory Ref. UID/ CEC/ 04516/ 2019); INESC-ID Ref. UID/CEC/50021/2019; BioISI Ref. UID/MULTI/04046/2103; LASIGE Research Unit Ref. UID/CEC/00408/ 2019. A major challenge in modelling and simulation is the need to combine expertise in both software technologies and a given scientific domain. When High-Performance Computing (HPC) is required to solve a scientific problem, software development becomes a problematic issue. Considering the complexity…
«Den dagen PC-en går i stykker, da er mye av min verden gått i stykker» : En kvalitativ studie om eldres bruk av Duka-PC
2019
Masteroppgave klinisk helsevitenskap ME520 - Universitetet i Agder 2019 Background:Information and communication technology (ICT) affects our everyday lives and the government wants it to be equal opportunities for everyone despite gender, age, background and economy. Many seniors want to be an active player in this digital everyday life. However, lack of knowledge and skills may affectthe confidence to get started. Technological solutions are needed that canmeet their needs and which are adjusted to the functional impairments the individual may have. The importance of facilitated training and user-friendly equipment can be of great value to achieve a greater degree of mastering and confide…
E-veselības portāla lietojamība senioru vērtējumā
2020
Bakalaura darba “E-veselības portāla lietojamība senioru vērtējumā” galvenais mērķis ir noskaidrot Eveseliba.gov.lv tīmekļa vietnes sadaļu, kurai var piekļūt autorizēti lietotāji, no lietojamības skatu punkta, senioru vidū no 60 līdz 69 gadiem. Pētījums tiek balstīts uz teorētisko modeli “Mijiedarbības trīs komponentu modeli” (The Interaction Triptych Model), kuru ir izstrādājuši divi teorētiķi: Giannis Taskonas(Giannis Tsakonas) un Kristos Papateodoru (Christos Papatheodorou). Tīmekļa vietnes analīze tiek veikta uz verbālā protokola pamata un modelī noteiktiem lietojamības kritērijiem.
Acceptance and Continuance Intention of Web-based Learning Technologies (WLT) Use among University Students in a Baltic Country
2006
This paper presents the acceptance and "continuance intention" of use for Web-based learning tools among University students in an Eastern European Country, namely Estonia. In this paper, we used the technology acceptance model (TAM), which was extended to include two external constructs: the technology and user characteristics. These two constructs were modeled to influence the perceived ease of use, and perceived usefulness constructs in the TAM. Further, another construct - continuance intention - in the information systems (IS) post-adoption literature was linked to the TAM. We used a sample of 72 students from four local higher educational institutions that have experience with a speci…
Experiences from global e-collaboration: Contextual influences on technology adoption and use
2005
The article presents a cross-case comparison of experiences from organizational adoption and use of e-collaboration technologies in two large global companies. Challenges in the global implementation process were found to increase with the organizational and geographical scope of the implementation, level of autonomy in the adoption process, cultural diversity, technological heterogeneity, and level of work process support embedded in the system. Alignment with existing collaborative work practices resulted in faster adoption of the technological solution. Highly competitive conditions restricted the resources available for training and experience transfer between projects. Clients’ prefere…
Conquering Fine-Grained Blends of Design Patterns
2008
The reuse of design patterns in realistic software systems is often a result of blending multiple pattern elements together rather than instantiating them in an isolated manner. The explicit description of pattern compositions is the key for (i) documenting the structure and the behavior of blended patterns and, (ii) more importantly, supporting the reuse of composite patterns across different software projects. In this context, this paper proposes a fine-grained composition language for describing varying blends of design patterns based on their structural and behavioural semantics. The reusability and expressiveness of the proposed language are assessed through its application to 32 compo…
Integrating usability work into a large inter-organisational agile development project: Tactics developed by usability designers
2015
We examined how usability activities were integrated in a large inter-organisational agile development project.The collaboration between the usability designers and agile team members was affected by the size and nature of the project.Results showed integration was achieved through 5 tactics employed by the usability designers.Three propositions for organising usability activities in agile projects were derived. In this paper we examine the integration of usability activities into a large inter-organisational agile development project. Inter-organisational agile projects possess unique attributes. They involve multiple stakeholders from different organisational contexts and are thus charact…
Testing the usability of the Rapid Impact Assessment Matrix (RIAM) method for comparison of EIA and SEA results
2008
Abstract This study examines how the results of Environmental Impact Assessment (EIA) and Strategic Environmental Assessment (SEA) could be compared using the Rapid Impact Assessment Matrix (RIAM) method. There are many tools and techniques that have been developed for use in impact assessment processes, including scoping, checklists, matrices, qualitative and quantitative models, literature reviews, and decision-support systems. While impact assessment processes have become more technically complicated, it is recognized that approaches including simpler applications of available tools and techniques are also appropriate. The Rapid Impact Assessment Matrix (RIAM) is a tool for organizing, a…
A proposal to elicit usability requirements within a model-driven development environment
2014
[EN] Nowadays there are sound Model-Driven Development (MDD) methods that deal with functional requirements, but in general, usability is not considered from the early stages of the development. Analysts that work with MDD implement usability features manually once the code has been generated. This manual implementation contradicts the MDD paradigm and it may involve much rework. This paper proposes a method to elicit usability requirements at early stages of the software development process such a way non-experts at usability can use it. The approach consists of organizing several interface design guidelines and usability guidelines in a tree structure. These guidelines are shown to the an…
