Medición de resultados en la estrategia CRM : Hacia un modelo holístico

2006

Este trabajo pretende contribuir a la investigación realizada en el ámbito la medición de resultados derivados de la estrategia CRM (Customer Relationship Management) . Con tal objetivo, primeramente definimos CRM como una filosofía de negocio que combina estrategia y tecnología en entornos tanto convencionales como virtuales (e-CRM). A continuación, destacamos la necesidad de contar con sistemas de medición por parte de las empresas que evalúen, de forma dinámica, el impacto de las iniciativas CRM y e-CRM sobre los resultados. Asimismo, realizamos una retrospectiva de las métricas utilizadas en el ámbito del marketing , destacando la tendencia hacia modelos scorecard , con un especial énfa…

An inter-laboratory comparison to evaluate the suitability of EN 1787 standard to detect irradiation in plant-origin foods with health benefits

2020

Abstract This paper reports the results of a study carried out to verify the applicability of the EN 1787 method, which uses the Electron Spin Resonance (ESR) technique for the identification of irradiated plant-origin foods with health benefits. The method was tested on samples of herbal ingredients of Plant Food Supplements (PFSs), nuts and fresh blueberries. Untreated and irradiated samples of Camellia sinensis (leaves) Ginkgo biloba (leaves), Glycine max (seeds), Silybum marianum (fruits), Vaccinium myrtillus (fruits), almonds, hazelnuts, peanuts, pistachios, walnuts and fresh blueberries were analysed. The work includes an inter-laboratory blind test involving five Italian laboratories…

Determinazione della componente gamma nella colone termica del reattore TRIGA di Pavia tramite Dosimetri ESR di alanina

2016

Negli ultimi anni il crescente interesse verso la radioterapia a cattura neutronica (internazionalmente nota come Neutron Capture Therapy - NCT) per il trattamento di neoplasie ha stimolato diverse attività di ricerca finalizzate alla caratterizzazione del fascio utilizzato e all'ottimizzazione delle procedure radioterapiche. Tra i vari sistemi dosimetrici trovano largo impiego i rivelatori a stato solido ESR (Risonanza di Spin Elettronico) a base di alanina che presentano diversi vantaggi come la tessuto equivalenza, la linearità della risposta in un ampio intervallo di dose, l'elevata stabilità dei radicali liberi radioindotti, la non distruttività della lettura del dosimetro e il basso c…

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…

Space-Time Forecasting of Seismic Events in Chile

2017

The aim of this work is to study the seismicity in Chile using the ETAS (epidemic type aftershock sequences) space‐time approach. The proposed ETAS model is estimated using a semi‐parametric technique taking into account the parametric and nonparametric components corresponding to the triggered and background seismicity, respectively. The model is then used to predict the temporal and spatial intensity of events for some areas of Chile where recent large earthquakes (with magnitude greater than 8.0 M) occurred.
