Shift-Invariant Canonical Polyadic Decomposition of Complex-Valued Multi-Subject fMRI Data with a Phase Sparsity Constraint
2020
Canonical polyadic decomposition (CPD) of multi-subject complex-valued fMRI data can be used to provide spatially and temporally shared components among groups with both magnitude and phase information. However, the CPD model is not well formulated due to the large subject variability in the spatial and temporal modalities, as well as the high noise level in complex-valued fMRI data. Considering that the shift-invariant CPD can model temporal variability across subjects, we propose to further impose a phase sparsity constraint on the shared spatial maps to denoise the complex-valued components and to model the inter-subject spatial variability as well. More precisely, subject-specific time …
From imprecise probability assessments to conditional probabilities with quasi additive classes of conditioning events
2012
In this paper, starting from a generalized coherent (i.e. avoiding uniform loss) intervalvalued probability assessment on a finite family of conditional events, we construct conditional probabilities with quasi additive classes of conditioning events which are consistent with the given initial assessment. Quasi additivity assures coherence for the obtained conditional probabilities. In order to reach our goal we define a finite sequence of conditional probabilities by exploiting some theoretical results on g-coherence. In particular, we use solutions of a finite sequence of linear systems.
Strictly convergent algorithm for an elliptic equation with nonlocal and nonlinear boundary conditions
2012
The paper describes a formally strictly convergent algorithm for solving a class of elliptic problems with nonlinear and nonlocal boundary conditions, which arise in modeling of the steady-state conductive-radiative heat transfer processes. The proposed algorithm has two levels of iterations, where inner iterations by means of the damped Newton method solve an appropriate elliptic problem with nonlinear, but local boundary conditions, and outer iterations deal with nonlocal terms in boundary conditions.
¿Cómo impulsa la Comunicación Integrada de Marketing la satisfacción del huésped?: una propuesta a través del conocimiento ecológico y la co-creación…
2022
[ES] La creciente necesidad de aumentar la eficacia de las estrategias de comunicación en el sector hotelero impulsa la investigación acerca de cómo es posible intensificar sus efectos. De entre las distintas alternativas, el enfoque CIM basado en la sostenibilidad empieza a adquirir cada vez más importancia. El presente trabajo tiene como objetivo examinar las relaciones entre la CIM para la sostenibilidad, el conocimiento ecológico, la co-creación de valor y la satisfacción. Sobre la base de los efectos en cadena que se investigan, se propone un modelo teórico, que se contrasta a partir de un estudio empírico con una muestra de 303 huéspedes, en hoteles de Kyiv (Ucrania). Los resultados r…
Conoscere il diritto
2023
Il modo di concepire la conoscenza del diritto varia nel corso del tempo ed è influenzato da molteplici fattori. Seguendo Norberto Bobbio è possibile distinguere due modelli ideal-tipici di giurista: il “custode” di un diritto pre-esistente e il “creatore” di un diritto perennemente in fieri e indeterminato. Tale alternativa è tuttavia soltanto apparente; anche quando la scienza giuridica postula l’esistenza di un diritto-oggetto in attesa di essere conosciuto, essa in effetti non fa altro che presupporre una immagine ideologicamente caratterizzata del diritto. Di conseguenza, lo studioso del diritto non è mai un osservatore neutrale. Così anche il diritto-oggetto “custodito” dalla scienza …
Consumer Information Services in Intercultural Tourism : An Ethnographic Study of Chinese Outbound Backpackers
2017
This paper reports the findings of an ethnographic study of Chinese outbound backpackers’ use and adoption of consumer information services (CIS) in an intercultural tourism setting. We apply McKenna et al.’s research model of consumers’ adoption of information services as the analytical lens for the interpretive qualitative study. The data gathering was conducted in four different countries. The findings of the study confirm linkages between four information service types and the use and adoption of CIS. The study also found that service types are more diversely linked than the earlier studies have predicted and therefore we propose a revised research model, which can be used for studying …
Digital content marketing in B2B contexts: The drivers of engagement and electronic word of mouth communication at international trade shows
2023
El potencial que representan las redes sociales como una herramienta de marketing es indiscutible, permiten compartir información, construir redes, e influir en consumidores y marcas. Aún más, las redes sociales contribuyen al engagement empresa a empresa (B2B por sus siglas en inglés), ofreciendo un entorno perfecto para su desarrollo. En este sentido, la literatura en marketing ha reconocido la utilidad de las redes sociales en la promoción de ferias comerciales internacionales (ITS por sus siglas en inglés) empresa a empresa. Adicionalmente, en tiempos de crisis como lo es el COVID-19, la comunicación es uno de los principales desafíos en la gestión de emergencias, y las redes sociales s…
Ethical Versus Conventional Banking: A Case Study
2018
The 2008 financial crisis has changed the structure of banking, generating public distrust in the conventional financial system. An alternative has emerged as a result of this lack of confidence. This alternative is known as ethical banking. A growing number of investors, asset managers, and financial intermediaries have incorporated sustainability considerations into their business practices. This paper discusses the origins of ethical banking and describes its primary characteristics. The goal is to determine whether ethical banking can be as profitable as conventional banking despite only investing in projects based on social values. A comparative analysis is performed to identify differ…
