Cross-national validation of the resources depletion-recovery model: An empirical study of Spanish and British theme park employees
Surface acting (SA) refers to the strategy whereby front-line employees hide their own emotions and fake those required of them within their role within customer service transactions. Although researchers have associated SA with burnout, evidence now suggests that this could be an indirect relationship. Building on the Conservation of Resources theory, it was hypothesised that the combined effect of emotional effort and lack of rewarding interactions with customers triggered by SA would explain the strong association between SA and burnout (Studies 1 and 2). Furthermore, building on psychological recovery literature, it was hypothesised that the effort invested in SA would be a weaker predictor of front-line employees’ burnout in cases when they reported higher levels of recovery ability as opposed to lower levels (Study 2). A cross-national and cross-sectional design was used, and participants were theme park employees from UK (Study 1, NUK =204) and Spain (Study 2, NSpain=211). The explanatory role of emotional effort and rewarding interactions was supported, and the buffering effect of recovery ability was confirmed. Strategies aimed at minimising burnout risk for employees who deal with customers on a regular basis in these countries are discussed
Cross-cultural comparison of Spanish and British “service-with-a-smile” outcomes
PurposeEmployees working in the leisure service industry are required to show positive emotions when dealing with customers. However, empirical evidence confirms that faking emotions can lead to burnout. In contrast, employees that try to experience the emotions required by the role (i.e. deep acting (DA)) can lead to healthier outcomes. However, little is known about the process that underpins the link between DA and positive outcomes. Building on Côte’s social interaction model of emotion regulation and evidence linking customer satisfaction and DA, it was hypothesized that DA would be associated with employees’ self-actualization through customer interactions. This, in turn, was expected to explain the influence that DA has on relevant job attitudes (i.e. commitment, efficacy, turnover intentions). The model was tested in two countries with different emotional culture: Spain (i.e. impulsive) and the UK (i.e. institutional). Although UK was expected to report higher levels of effortful DA, the hypothesized process was expected to be the same. The paper aims to discuss these issues.Design/methodology/approachA cross-national design with theme park employees from Spain (n = 208) and UK (n = 204) was used. Hypotheses were tested with multigroup confirmatory factor analysis.
FindingsThe relationship between job commitment and DA was mediated by self-actualization, and commitment partially explained the association between DA and professional efficacy in both countries. The impulsive-oriented country showed lower levels of DA and more positive job attitudes.Originality/valueIt is concluded that training employees to re-interpret costume
Axion Like Particles and the Inverse Seesaw Mechanism
Light pseudoscalars known as axion like particles (ALPs) may be behind
physical phenomena like the Universe transparency to ultra-energetic photons,
the soft -ray excess from the Coma cluster, and the 3.5 keV line. We
explore the connection of these particles with the inverse seesaw (ISS)
mechanism for neutrino mass generation. We propose a very restrictive setting
where the scalar field hosting the ALP is also responsible for generating the
ISS mass scales through its vacuum expectation value on gravity induced
nonrenormalizable operators. A discrete gauge symmetry protects the theory from
the appearance of overly strong gravitational effects and discrete anomaly
cancellation imposes strong constraints on the order of the group. The
anomalous U symmetry leading to the ALP is an extended lepton number and
the protective discrete symmetry can be always chosen as a subgroup of a
combination of the lepton number and the baryon number.Comment: 29pp. v4: published version with erratum. Conclusions unchange
Diseño de un controlador basado en observador para un sistema de torsión
Este artículo presenta el diseño de un controlador basado en observador para un sistema de torsión. Se propone un esquema de un controlador dinámico continuo para regular una clase de sistemas mecánicos totalmente actuados con fricción seca. El sistema físico se puede observar en la Fig. 1, y el cual es explicado por (1) y (2). En este caso, el objetivo de control es regular la variable no actuada, limitando las amplitudes de la posición y velocidad de la articulación sobre la que se ejecuta la acción. Se diseñará un observador de primer orden y posteriormente se verifican los resultados obtenidos por el controlador en modos deslizantes en comparación con un controlador PID. El desempeño de los controladores propuestos se ilustran con resultados numéricos y experimentales, para los cuales se tendrán en cuenta los siguientes factores: respuesta dinámica transitoria (rapidez y estabilidad relativa) y seguimiento de señales de referencia (error de estado estable).Universidad Nacional de ColombiaColcienciasBanco Mundia
High temperature behavior of Sr-doped layered cobaltites Y(Ba1-xSrx)Co2O5.5: phase stability and structural properties
In this article we present a neutron diffraction in-situ study of the thermal
evolution and high-temperature structure of layered cobaltites Y(Ba, Sr)Co2
O5+{\delta}. Neutron thermodiffractograms and magnetic susceptibility
measurements are reported in the temperature range 20 K <= T <= 570 K, as well
as high resolution neutron diffraction experiments at selected temperatures.
Starting from the as-synthesized samples with {\delta} ~ 0.5, we show that the
room temperature phases remain stable up to 550 K, where they start loosing
oxygen and transform to a vacancy-disordered "112" structure with tetragonal
symmetry. Our results also show how the so-called "122" structure can be
stabilized at high temperature (around 450 K) in a sample in which the addition
of Sr at the Ba site had suppressed its formation. In addition, we present the
structural and magnetic properties of the resulting samples with a new oxygen
content {\delta} ~ 0.25 in the temperature range 20 K <= T <= 300 K
Individually-rational collective choice
There is a collection of exogenously given socially-feasible sets, and, for each one of them, each individual in a group chooses from an individually-feasible set. The fact that the product of the individually-feasible sets is larger than the socially-feasible set notwithstanding, there arises no conflict between individual choices. Assuming that individual preferences are random, I characterize rationalizable collective choices
