An Overview of 5G Slicing Operational Business Models for Internet of Vehicles, Maritime IoT Applications and Connectivity Solutions
2021
Identification of ecosystems and Business Models (BM) is an important starting point for new complex system development. The definition of actor (or stakeholder) roles and their interactions (at both business and technical levels), together with target scenarios and use cases, provide essential input information for further system requirement collection and architecture specification. The powerful and flexible Fifth Generation (5G) network slicing technology, which is capable of creating virtually isolated and logically parallel networks, enables a large range of complex services and vertical applications. Although various terminologies and models have been proposed in recent years for BMs …
ICT-SUSTOUR and MARKETOUR: Two second language acquisition projects through a virtual learning environment
2009
We are presenting a methodological approach that aims to increase students' motivation by asking them to develop tasks based on professional settings. In order to meet this objective a collaborative methodology was designed and applied to two multidisciplinary projects: MARKETOUR and ICT-SUSTOUR. Both projects made students face real workplace situations by working collaboratively through the use of a virtual learning environment (VLE) and other information technology (IT) tools at a national and international level. The methodology proposed offers students a professional scenario in which they are required to develop purpose-based tasks using IT. A virtual learning environment was devised …
Student knowledge and learning skill modeling in the learning environment `forces'In order to prevent further delays in publication this paper has be…
1998
Abstract In this paper we present a student module modeling knowledge states and learning skills of students in the field of Newtonian dynamics. Student data recorded during the exploratory activity in microworlds are used to infer mental representations concerning the concept of force. A fuzzy algorithm able to follow the cognitive states the student goes through in solving a task and to interpret the monitored changes is discussed.
Re-Infrastructuring for eHealth: Dealing with Turns in Infrastructure Development
2017
In this paper, we examine infrastructuring in the context of developing national, public eHealth services in Norway. Specifically, we analyze the work of a project team engaged in the design and development of new web-based capabilities for communication between citizens and primary healthcare practitioners. We frame the case as a study of re-infrastructuring to signify a particular occasion of infrastructuring that entails facilitating a new logic within established social and technological networks. To make sense of the particularities of re-infrastructuring, we draw from research in infrastructure studies which considers embeddedness as a resource in infrastructure evolution. We analyze …
Teachers’ information and communication technology competences: A structural approach
2016
Teachers' information and communication technology (ICT) competences are a key variable to integrate such resources into the teaching-learning process. One problem with teachers' ICT competences is the proliferation of various frameworks which entail a lack of definition of these competences. The objective of this article is twofold: to establish a basic framework that shapes the subsets of ICT competences (technological and pedagogical) in all teachers at all levels (Primary, Secondary and Higher Education); to determine how various personal and contextual factors influence these subsets. For this purpose, a study of secondary analysis has been made with data from two survey design studies…
Barriers to the use of mobile sales force automation systems: a salesperson’s perspective
2015
Purpose – The purpose of this paper is to examine the barriers associated with the adoption and use of mobile sales force automation (SFA) systems from a salesperson’s perspective. Design/methodology/approach – A qualitative investigation of two business-to-business companies was conducted. Data collected from ten semi-structured interviews with directors or sales managers were analyzed to understand the main barriers to SFA system adoption. Findings – The study confirms the existence of three barriers (customer knowledge, quality of information and the characteristics of mobile devices) to a mobile SFA system use and identifies two additional barriers: lack of time and optimization issues…

El deudor ante la solicitud de declaración de concurso: (una primera aproximación al artículo 17 del Proyecto de Ley Concursal)
2003
Ante el procedimiento de declaración de concurso, el sujeto pasivo tiene, según el artículo 17 PLC, dos alternativas: allanarse u oponerse. Sin embargo, existen más alternativas: recurrir la providencia de admisión a trámite, plantear declinatoria, no contestar, o presentar solicitud del propio concurso. La autora analiza cada una de las posibilidades del deudor, diferenciando las que originan una resolución judicial estimatoria de la pretensión concursal sin anterior procedimiento contradictorio: allanamiento, inactividad y solicitud de la declaración de concurso; y la oposición del deudor que se plantea como la opción ordinaria a seguir por el sujeto pasivo que exige debate contradictorio…

La transformación de la esfera familiar en el Derecho de extranjería español
2013
espanolLa articulacion legal del derecho a la vida familiar en Derecho de extranjeria se rige por una logica restrictiva cuyo alcance implica una autentica "metamorfosis" de las relaciones familiares. De un lado, la ley combina una composicion nuclear y dependiente para promover un ideal tipo dominante de familia que resulta abiertamente excluyente de otras realidades familiares existentes en la realidad social. Y de otro lado, neutraliza la diversidad del entorno familiar modulando otras formas de reconocimiento con vistas a instaurar un modelo de familia preferiblemente no conflictivo. Desde una perspectiva critica, este trabajo se centra el verdadero alcance del regimen de la reagrupacio…
