An analysis of e-business adoption and its impact on relational quality in travel agency–supplier relationships

2010

Abstract This study analyzes how managers of retail travel agencies perceive the antecedents and consequences of adopting e-business in their supplier relationships. A comprehensive model integrating its antecedents and relational effects is developed and empirically tested using SEM. The study surveyed 101 travel agents in Spain. Research findings indicate that customer pressure has a strong influence on e-communication practices. E-communication with the travel agency's supplier and the pressure exerted by the sector are the main antecedents for e-procurement. Effects of e-business on relational quality are contradictory. E-procurement influences negatively on trust. Conversely, e-communi…

Structural Health Monitoring of Cracked Beam by the Dual Reciprocity Boundary Element Method

2012

In this paper a 2D boundary element model is used to characterize the transient response of a piezoelectric based structural health monitoring system for cracked beam. The BE model is written for piezoelectric non-homogeneous problem employing generalized displacements. The dual reciprocity method is used to write the mass matrix in terms of boundary parameters only. The multidomain boundary element technique is implemented to model non-homogeneous and cracked configuration, unilateral interface conditions are also considered to prevent the physical inconsistence of the overlapping between interface nodes belonging to the crack surfaces. To assess the reliability and the effectiveness of th…

On the dynamic behavior of piezoelectric active repair by the boundary element method

2011

The dynamic behavior of piezoelectric active repair bonded on cracked structures is analyzed in this article. The boundary element code used to perform the simulations is implemented in the framework of piezoelectricity in order to model the coupling between the elastic and the electric fields, which represents the most important feature of piezoelectric media. The fracture mechanics problem, i.e. the crack, as well as the bonding layer between the host structure and the active patch is modeled by means of the multidomain technique provided with an interface spring model. More particularly, the spring interface model allows considering the bonding layer as a zero-thickness elastic ply char…

The interplay of reciprocity propensity and inequality aversion in two-person games

2020

Economic normative models assume that economic actors are fully rational and selfish while recent studies acknowledge the emotional influence of an economic decision and call for further investigation of biases in decision making. Most decisions involve multiple actors who make decisions following a sequential path as reflected by decision trees; this contingency makes a call for the game theory contribution in the economic decision field. Two-person games are widely used to represent a typical framework of economic decisions. This study aims at further investigating psychological biases affecting decisions in a two-person sequential game. So far similar studies have focused on the principa…

Doni funesti. Miti di scambi pericolosi nella letteratura latina

2018

«I doni sono come gli ami» avverte Marziale. «Catturano anche gli dèi» afferma Ovidio. «Sono l’inganno in cui di solito incappano i re» osserva Seneca. La forza calamitante del dono, la sua natura seducente e pericolosa, emerge con chiarezza dall’analisi del sapere mitico romano e delle sue riscritture letterarie. I Romani, del resto, conoscevano bene il potere attrattivo dei doni, la loro capacità di condizionare i comportamenti e le dinamiche di relazione. Erifile è soggiogata dalla collana di Armonia, Mida è accecato dalla sua fame d’oro, Creusa è ingannata dai doni nuziali; Didone brucia con sé quelli dell’amato, Semele e Fetonte ne saranno bruciati. Il dono promesso è un rischio, il do…

La fides e la fraus: i doni del tiranno nel Thyestes di Seneca

2019

Nel Thyestes, Seneca riscrive la pratica del dono (536, 984) come strumento della vendetta del tiranno, che ne sfrutta il potere di attrazione. Combinando la categoria della fides con il meccanismo della fraus, Atreo intende mettere in scena un inganno in grado di soddisfare le “inique aspettative” (spes improba, 295) di Tieste, che spera di ottenere il regno (regna nunc sperat mea, 289), e fornirgli una garanzia tangibile di pace (fides pacis, 294). Una tale dinamica prende la forma di un “dono simulato”, una pratica di reciprocità in cui Atreo svolge il ruolo del donatore (dans) e Tieste è indotto ad assumere quello del destinatario (accipiens). Il tiranno lo rappresenta come un modo per …

SURFACE SUBGROUPS OF RIGHT-ANGLED ARTIN GROUPS

2007

We consider the question of which right-angled Artin groups contain closed hyperbolic surface subgroups. It is known that a right-angled Artin group $A(K)$ has such a subgroup if its defining graph $K$ contains an $n$-hole (i.e. an induced cycle of length $n$) with $n\geq 5$. We construct another eight "forbidden" graphs and show that every graph $K$ on $\le 8$ vertices either contains one of our examples, or contains a hole of length $\ge 5$, or has the property that $A(K)$ does not contain hyperbolic closed surface subgroups. We also provide several sufficient conditions for a \RAAG to contain no hyperbolic surface subgroups. We prove that for one of these "forbidden" subgraphs $P_2(6)$, …

Informal male caregivers in the city of Valencia. An experience of reciprocity

2018

Este artículo forma parte de un estudio de la Universidad de Valencia donde se analiza la percepción que algunos hombres tienen acerca del cuidado de personas adultas (mayores y/o discapacitadas) que ellos realizan de manera informal en su entorno familiar en la ciudad de Valencia. A través de entrevistas en profundidad, identificamos, la responsabilidad que estos hombres se toman con la persona cuidada a través del establecimiento de procesos de reciprocidad. Dicha reciprocidad destaca como un elemento positivo a extraer de sus vivencias que permite reivindicar el cuidado como un valor positivo y no exclusivo de ningún género. This article is part of a study from the University of Valencia…

Testing the Trust Game with undergraduates: An experiment with wealth heterogeneity

2017

Ponència presentada a 3rd International Conference on Higher Education Advances, HEAd’17, Universitat Politècnica de València, València, 2017 Trust, reciprocity and a fair distribution of resources are cruzial in the sustainability of any economic system. As a matter of fact, those are values that should be promoted among the new generations, especially among university students enrolled in degrees that are related to economics. Under this context, we are interested in enhancing criticism and active reflection among undergraduates with respect to social values. With such a goal in mind, we designed a two step classroom task that includes playing the Trust Game (TG) in the first place and, s…
