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…

Metrics Framework for Cycle-Time Reduction in Software Value Creation

2015

Agile software development methodologies driving cycle-time reduction have been shown to improve efficiency, enable shorter lead times and place a stronger focus on customer needs. They are also moving the process development focus from cost-reduction towards value creation. Optimizing software development based on lean and agile principles requires tools and metrics to optimize against. We need a new set of metrics that measure the process up to the point of customer use and feedback. With these we can drive cycle time reduction and improve value focus. Recently the lean startup methodology has been promoting a similar approach within the startup context. In this paper, we develop and vali…

Advances in mobile financial services: a review of the literature and future research directions

2022

PurposeUsing the theory, construct, method, moderator (TCMM) format, this framework-based review critically analyses the mobile financial services (MFSs) field through a detailed synthesis and analysis of a sample of mainstream empirical research published in various scientific journals within the period 2009–2020.Design/methodology/approachThe authors followed a three-step structured approach suggested by Webster and Watson (2002) to search for the literature to synthesise the global perspectives on MFSs and their associated applications and systems. The literature research resulted in the identification of 115 most relevant articles.FindingsThe authors identified three major categories or…

About time

2019

Purpose The purpose of this paper seeks to develop a motivation-based complementary framework for temporally dynamic user preferences to facilitate optimal timing in web personalisation. It also aims to highlight the benefits of considering user motivation when addressing issues in temporal dynamics. Design/methodology/approach Through theory, a complementary framework and propositions for motivation-based temporal dynamics for further testing are created. The framework is validated by feeding back findings, whereas some of the propositions are validated through an experiment. Findings The suggested framework distinguishes two ways (identifying/learning and shifting) of using a motive-base…

The Narrative Approach to Research Professional Identity: Relational, Temporal, and Dialogical Perspectives

2022

In this chapter, we present the narrative approach as applied in the field of professional learning. The specific aim is to present the methodological opportunities and concerns it raises in research on professional identity within the sociocultural frames of work environments. We utilise examples from empirical studies that have employed a range of narrative methods to collect and analyse datasets. The datasets include individuals’ written and spoken narratives, encompassing the told experiences of their identities, and the meanings underlying these. We illustrate how a particular strength of narrative research lies in its ability to portray temporal pathways through the phenomena under in…

Customer Value Framework and Recommendation Intention: The Moderating Role of Customer Characteristics in an Online Travel Community

2019

The aim of this study was to develop and test a model that examined the interactions among the customer value framework, recommendation intention and customer characteristics in an online travel community (OTC). Data were obtained using Amazon Mechanical Turk from 251 members of an OTC as a sample. The partial least squares method was used to analyse the data. We found that all the variables of the customer value framework, including functional value, hedonic value and social value, were positively related to recommendation intention. In addition, using multi-group analyses, the study found differences between how different customer segments perceive each of the value dimensions and their e…
