How modeling helps in developing self-sovereign identity governance framework: An experience report
2022
Digital Identity has become a topic that attracts the attention of researchers due to the enormous number of services that have been provided online recently. Researchers face many obstacles regarding the security, privacy, and utility of digital identity. Self-Sovereign Identity (SSI) ecosystems provide a solution for digital identity, in addition to providing a decentralized human-centric paradigm that enables users to own and control their identity. Governance framework (GF) is a key challenge in building SSI ecosystems for two reasons. First, the GF needs to address various aspects such as user needs, standards, laws, and business requirements in an ecosystem. Second, the ecosystem cons…
Historia y evolución del acogimiento familiar de menores y el contexto de la Comunidad Valenciana
2012
En este articulo presentamos la historia y evolución del Sistema de Protección a la Infancia, y más concretamente el recurso del acogimiento familiar de menores, a lo largo de los últimos veinticinco años. En el mismo diferenciamos dos partes: La primera, referida a la génesis del marco legislativo -internacional y estatal-, y la concreción de las modalidades de acogimiento en familia ajena y extensa. En la segunda parte se desarrolla el transcurso del acogimiento familiar de menores en el contexto de la Comunidad Valenciana. This article presents the history and evolution undergone over the last twenty-five years by the System for Minor Protection, and more specifically the solution of fos…
Challenges in Marketing Communications During the COVID-19 Pandemic
2022
The purpose of this study is to explore how tourism and hospitality firms managed marketing communications (marcom) since the COVID-19 outbreak and to propose a conceptual framework on marcom challenges that the pandemic crisis has brought to the industry. In-depth interviews were conducted with tourism and hospitality managers in Croatia, a destination that registered remarkable tourism results in 2021. The proposed conceptual framework reflects the adaptation process and major changes in B2B and B2C communication since the COVID-19 outbreak on one hand and resulting strategic opportunities for marcom managers on the other, discussed in terms of practical implications. To the best of the a…
The Educational Situation Quality Model: A New Tool to Explain and Improve Academic Achievement and Course Satisfaction
2019
Students’ academic achievement is a major concern among countries. Governments spent a lot of money on education to improve students’ competences at all levels of education. Despite the enormous amount of money invested and the reforms made to curricula in many countries in recent years, these measures are not generally producing the desired results according to the data of International Performance Measurement programs for students (e.g., Program for International Student Assessment-PISA by OECD). Given the importance of this issue, this article presents an instructionalmotivational model developed in the last decade to explain and improve students’ learning outcomes, e.g., academic achiev…
Data from: The relevance of ecological status to ecosystem functions and services in a large boreal lake
2015
1. Environmental conventions aim to protect ecosystem structures and functions to provide goods and services for mankind. The degree of aquatic ecosystem naturalness, or ecological status as it is defined in the Water Framework Directive (WFD) of the European Union, is notionally linked to supplies of ecosystem services. In practice these links have rarely been documented or even investigated and, to justify conservation and management objectives based on the status indicators, it is essential to demonstrate their relationships to ecosystem functions and services. 2. The WFD requires member states to classify their surface waters aiming to achieve good ecological status of water bodies. How…
On the Use of XML in Medical Imaging Web-Based Applications
2016
The rapid growth of digital technology in medical fields over recent years has increased the need for applications able to manage patient medical records, imaging data, and chart information. Web-based applications are implemented with the purpose to link digital databases, storage and transmission protocols, management of large volumes of data and security concepts, allowing the possibility to read, analyze, and even diagnose remotely from the medical center where the information was acquired. The objective of this paper is to analyze the use of the Extensible Markup Language (XML) language in web-based applications that aid in diagnosis or treatment of patients, considering how this proto…
Conceptual changes in lease accounting: Regulatory and academic challenges
2019
El objetivo principal de este trabajo es demostrar que el posicionamiento de los emisores de normas contables y el de los grupos de presión es coherente con la Teoría de la Ideología de la regulación y la Teoría Positiva de la Contabilidad de los efectos económicos, respectivamente. Sin embargo, contrariamente a la literatura previa de lobbying, argumentamos que en un contexto internacional y tras a˜nos de experiencia con las Normas Internacionales de Información Financiera (NIIF), todos los agentes, y no solo los emisores de las normas, utilizan aspectos conceptuales y técnicos, ya que los grupos de interés, fundamentalmente los preparadores, prevén hacer más efectiva su actividad de lobby…
Acceptability, reach and implementation of a training to enhance teachers’ skills in physical activity promotion
2020
This is a pre-print of a published study: Renko, E., Knittle, K., Palsola, M. et al. Acceptability, reach and implementation of a training to enhance teachers’ skills in physical activity promotion. BMC Public Health 20, 1568 (2020). https://doi.org/10.1186/s12889-020-09653-x Background: In order to achieve real-world impacts, successful behavior change interventions need to be scaled up and broadly implemented. Implementation is challenging however, and the factors influencing successful implementation are not fully understood. This study describes the nationwide implementation of a complex theory-based program to promote physical activity and reduce sedentary behavior in vocational school…
Exploiting the Potential of New Coordination Frameworks for Technological Applications – from Temperature Sensing to Magnetic Storage
2022
Esta tesis es sobre el diseño, síntesis y caracterización de nuevos Polimeros de Coordinación (CPs), porosos o no, que muestran propiedades magnéticas y/o ópticas, para explotar su potencial en diversas aplicaciones tecnológicas. El diseño de estos materiales requiere una atención particular en la selección de los componentes básicos moleculares, los ligandos orgánicos y los nodos metálicos. Para construir CP con diferentes propiedades físicas, se han elegido derivados de carboxilato y anilato. En particular, el ácido 1,3,5-bencentricarboxílico (H3BTC, ácido trimésico), un ligando bioacompatible que permite construir polimeros organometálicos 3D robustos, y el 3,6-ditriazolil-2,5 -dihidroxi…
Decomposition Process of Carboxylate MOF HKUST-1 Unveiled at the Atomic Scale Level
2016
HKUST-1 is a metal-organic framework (MOF) which plays a significant role both in applicative and basic fields of research, thanks to its outstanding properties of adsorption and catalysis but also because it is a reference material for the study of many general properties of MOFs. Its metallic group comprises a pair of Cu2+ ions chelated by four carboxylate bridges, forming a structure known as paddle-wheel unit, which is the heart of the material. However, previous studies have well established that the paddle-wheel is incline to hydrolysis. In fact, the prolonged exposure of the material to moisture promotes the hydrolysis of Cu-O bonds in the paddle-wheels, so breaking the crystalline n…
