LA INFLUENCIA DE LA IMPLICACIÓN CON EL ANUNCIO EN EL PROCESO DE FORMACIÓN DE ACTITUDES
2001
Taking as its core the attitude toward the advertisement, this study attempts to determine the mechanisms through which advertising influences consumers' attitudes and buying behaviour. These mechanisms are analysed in terms of involvement with the message and with the execution of the ad, and in terms of the strength of the arguments used in the ad. The study finds that the involvement with the message and with the execution of the ad, determinates the antecedents and consequences of the ad. But the strength of the arguments does not explain these relations. En la presente investigación se pretende tomando como núcleo central de la misma la actitud hacia el anuncio, determinar los mecanism…
?Almost? mean-field ising model: An algebraic approach
1991
We study the thermodynamic limit of the algebraic dynamics for an "almost" mean-field Ising model, which is a slight generalization of the Ising model in the mean-field approximation. We prove that there exists a family of "relevant" states on which the algebraic dynamics αt can be defined. This αt defines a group of automorphisms of the algebra obtained by completing the standard spin algebra with respect to the quasiuniform topology defined by our states. © 1991 Plenum Publishing Corporation.
Superstable cycles for antiferromagnetic Q-state Potts and three-site interaction Ising models on recursive lattices
2013
We consider the superstable cycles of the Q-state Potts (QSP) and the three-site interaction antiferromagnetic Ising (TSAI) models on recursive lattices. The rational mappings describing the models' statistical properties are obtained via the recurrence relation technique. We provide analytical solutions for the superstable cycles of the second order for both models. A particular attention is devoted to the period three window. Here we present an exact result for the third order superstable orbit for the QSP and a numerical solution for the TSAI model. Additionally, we point out a non-trivial connection between bifurcations and superstability: in some regions of parameters a superstable cyc…
Segmentation, involvement and the reach-engagementrelationship: evidence from a QR code advertising campaign
2013
This paper presents a procedure that practitioners must follow before assessing the reach-‐engagement relationship in a “pull” campaign. It is suggested to check for the independence between this relationship and that between segmentation and product involvement. If the two relationships are independent, then segmentation becomes less relevant when assessing the reach-‐engagement relationship. Otherwise, an unobservable segmentation variable must be accounted for in the reach-‐engagement relationship. These aspects of segmentation are never mentioned in the extant literature, which treats segmentation in “pull” campaigns the same way in which targeting is designed in “push” campaigns. Th…
The Effect of the Return of Serve on the Server Pair’s Movement Parameters and Rally Outcome in Padel Using Cluster Analysis
2019
Purpose: The pressure exerted on racket sports players by the service has been well documented. Whilst the return of serve has been suggested through qualitative interviews as being of similar importance there is a dearth of quantitative data to support this contention. This study analyzed time, speed, and distance parameters related to the outcome of the return of serve (ROS) in Padel, a sport similar to tennis but played on a court bounded by walls and played in doubles format only. Methods: Matches (n = 18) at two tournaments, sanctioned by the Valencian Federation, in 2012 were recorded and processed using Tracker software. ROS shot type (flat or lob), ball location, players’ positions …
News Selection Within Customer Magazines
2017
Customer magazines blur the boundaries between journalistic reporting and organizational information. On the one hand, customer magazines are intended to communicate the interests, brands, products, and services of an organization. On the other hand, their topics, style, and layout resemble those of journalistic publications, from which readers expect independent and objective reporting. While customer magazines are distributed in high numbers throughout different industries and play an increasingly important role in the media landscape, they have hardly been the focus of researchers to date. It is therefore quite unclear how editorial decisions are made within these publications. This stud…
A universal tensor network algorithm for any infinite lattice
2018
We present a general graph-based Projected Entangled-Pair State (gPEPS) algorithm to approximate ground states of nearest-neighbor local Hamiltonians on any lattice or graph of infinite size. By introducing the structural-matrix which codifies the details of tensor networks on any graphs in any dimension $d$, we are able to produce a code that can be essentially launched to simulate any lattice. We further introduce an optimized algorithm to compute simple tensor updates as well as expectation values and correlators with a mean-field-like effective environments. Though not being variational, this strategy allows to cope with PEPS of very large bond dimension (e.g., $D=100$), and produces re…
Formation of Ordered Structures in Quenching Experiments: Scaling Theory and Simulations
1987
In this note we want to address the particular problem of the formation of ordered structures resulting from “quenching experiments”. The generic experimental situation is depicted in Figure 1. Initially the system is in an unordered random state in the one-phase region. Then the temperature is lowered (for some systems like polymers the coexistence curve is inverted so that the temperature must be raised) until the system is in the two phase region. The system is now in a non-equilibrium situation and evolves toward equilibrium. It is during the evolution toward equilibrium that the system develops ordered structures /1,2/.
The radium Era: radioactivity and advertising of miracle products in the dawn of the 20th century in Spain
2020
El descubrimiento de la radiactividad a finales del siglo XIX proporcionó el conocimiento de un nuevo fenómeno natural que fue utilizado como reclamo sin validación científica en un repertorio de productos, remedios y terapias que en el primer cuarto del siglo XX se anunciaron profusamente en la prensa española. Las experiencias de los manantiales con el agua radiactiva o los emanatorios urbanos fueron algunos de los casos más frecuentes de esas terapias o productos milagro en los que la publicidad de la época utilizaba la ciencia desde el abuso, el desconocimiento o las falsas atribuciones para prometer curaciones para todo tipo de dolencias sin ninguna efectividad práctica. The discovery …
Finite-size scaling in Ising-like systems with quenched random fields: Evidence of hyperscaling violation
2010
In systems belonging to the universality class of the random field Ising model, the standard hyperscaling relation between critical exponents does not hold, but is replaced by a modified hyperscaling relation. As a result, standard formulations of finite size scaling near critical points break down. In this work, the consequences of modified hyperscaling are analyzed in detail. The most striking outcome is that the free energy cost \Delta F of interface formation at the critical point is no longer a universal constant, but instead increases as a power law with system size, \Delta F proportional to $L^\theta$, with $\theta$ the violation of hyperscaling critical exponent, and L the linear ex…
