Sticking with your university: the importance of satisfaction, trust, image, and shared values
2016
In a context of increasing competition and financial difficulties for higher education institutions, alumni loyalty is a key factor for survival and success. This study tests a model derived from a relationship marketing perspective to investigate the roles of four variables (brand image, trust, satisfaction, and shared values) in the direct and indirect explanation of alumni loyalty. Based on a literature review, a theoretical model is proposed and tested through structural equations modeling for a sample of 1000 university alumni. The results reveal three direct antecedents of alumni loyalty (satisfaction, shared values, and trust) and one indirect antecedent (university brand image). In …
Museum visitors’ heterogeneity and experience processing
2019
Abstract This research examines the relationships between affective and cognitive antecedents and consequences of satisfaction under a market heterogeneity approach. It includes co-creation of preparatory activities. The sample consisted of 276 museum visitors in London. Two analysis have been conducted: structural equation model and latent class path analysis. The paper contributes to the development of a theoretical framework for further understanding of service experience in which co-creation plays an important role. Two segments were identified: 1) emotional (with lower degree of co-creation, equally distributed by age and nationality); 2) rational (higher degree of co-creation, younger…
How can perceived consistency in marketing communications influence customer-brand relationship outcomes?
2020
Abstract This paper examines the impact of perceived consistency in marketing communications on customer–brand relationship outcomes. The perception of consistent message and image through different marketing communication tools is one of the basic principles of the integrated marketing communications (IMC) approach. Although literature suggests that IMC might have an influence on customer–brand relationship outcomes, empirical evidence that supports this assumption is still weak and inconclusive. Three main brand relationship outcomes are established for the purpose of the study, i.e. trust, commitment, and loyalty. The relationships between perceived communication consistency and brand ou…
Lettura stratigrafica degli elevati e restituzione 3d del monumento (VII-VIII secolo)
2009
Il contributo concerne lo studio ricostruttivo della chiesa paleocristiana nella seconda fase di vita dell'edificio. L'ipotesi ricostruttiva, e il modello 3D, si è basata sullo studio delle fonti dirette: rilievo, dati di scavo archeologico e lettura stratigrafica degli elevati. The contribution concerns the reconstructive study of the early Christian church in the second phase of the building's life. The reconstructive hypothesis, and the 3D model, was based on the study of direct sources: survey, archaeological excavation data and stratigraphic reading of the elevations.
Effective simulation model and new control strategy to improve energy efficiency in hybrid electric land vehicle
2014
The main objectives of this work is to develop an effective modeling method for an easydeployment of a control strategy, to review and study an optimal control strategy for a specific application, and to analyze improvement that can be effected to engine for better efficiency in hybrid vehicle architecture. The scopes of this work include the simulation part of the studied system and its validation with experimental results. Study cases are used to analyze optimization that can be effected to the original system. A well established optimization tool is chosen to optimize the actual control strategy and becomes a benchmark of a new optimal control strategy to be deployed in the system. A pre…

Digital Image Analysis Applied to Tumor Cell Proliferation, Aggressiveness, and Migration-Related Protein Synthesis in Neuroblastoma 3D Models
2020
Patient-derived cancer 3D models are a promising tool that will revolutionize personalized cancer therapy but that require previous knowledge of optimal cell growth conditions and the most advantageous parameters to evaluate biomimetic relevance and monitor therapy efficacy. This study aims to establish general guidelines on 3D model characterization phenomena, focusing on neuroblastoma. We generated gelatin-based scaffolds with different stiffness and performed SK-N-BE(2) and SH-SY5Y aggressive neuroblastoma cell cultures, also performing co-cultures with mouse stromal Schwann cell line (SW10). Model characterization by digital image analysis at different time points revealed that cell pro…
Revista electrónica de investigación y evaluación educativa
2010
Este trabajo tiene el propósito de mostrar el uso de la metodología de Modelos de Ecuaciones Estructurales (SEM) para validar la estructura conceptual de cuestionarios de contexto que se utilizan en los estudios nacionales e internacionales para evaluar el logro educativo de los escolares. Desgraciadamente, los organismos evaluadores no destinan los mismos recursos técnicos a los cuestionarios de contexto que a las pruebas de aprendizaje, por lo que rara vez los primeros son sujetos a estudios de validez. Para mostrar el uso de la metodología SEM, se seleccionó el cuestionario dirigido a alumnos que utilizó el Instituto Nacional para la Evaluación de la Educación (INEE) para conocer los fac…
Physically based modeling of rainfall-triggered landslides: a case study in the Luquillo forest, Puerto Rico
2013
This paper presents the development of a rainfall-triggered landslide module within an existing physically based spatially distributed ecohydrologic model. The model, tRIBS-VEGGIE (Triangulated Irregular Networks-based Real-time Integrated Basin Simulator and Vegetation Generator for Interactive Evolution), is capable of a sophisticated description of many hydrological processes; in particular, the soil moisture dynamics are resolved at a temporal and spatial resolution required to examine the triggering mechanisms of rainfall-induced landslides. The validity of the tRIBS-VEGGIE model to a tropical environment is shown with an evaluation of its performance against direct observations made w…
On Metadata Support for Integrating Evolving Heterogeneous Data Sources
2019
With the emergence of big data technologies, the problem of structure evolution of integrated heterogeneous data sources has become extremely topical due to dynamic and diverse nature of big data. To solve the big data evolution problem, we propose an architecture that allows to store and process structured and unstructured data at different levels of detail, analyze them using OLAP capabilities and semi-automatically manage changes in requirements and data expansion. In this paper, we concentrate on the metadata essential for the operation of the proposed architecture. We propose a metadata model to describe schemata and supplementary properties of data sets extracted from sources and tran…
