How emotional response mediates servicescape impact on post consumption outcomes: An application to opera events
2020
Abstract The purpose of this study is to examine how emotions mediate the impact of a holistic servicescape -physical and social- on post-consumption outcomes in the performing arts. Partial Least Square (PLS) was conducted to test the mediation hypothesized relationships on a sample of 867 opera goers. The proposed research model was largely supported by the evidence, and the mediating role of emotions was confirmed. Servicescape influences direct and indirectly attendees' post consumption in opera given that emotions play a partial mediating role which is greater in the case of positive emotions. Based on the results, this study offers specific theoretical and managerial implications conc…
Recapturing Joaquín “Chapo” Guzmán in the Mexican Press: An Analysis of the Front Page of El Universal, Reforma, Excélsior, and La Jornada in 2016
2018
This article, whose aim is to know exactly how the headlines of Mexico's four main newspapers have reported on the recapture of Joaquín Guzmán, will show the results of an analysis of the journalistic content of these four Mexican newspapers. These are general papers, which published information on their front page regarding the recapture of the drug trafficker Joaquín 'Chapo' Guzmán. The events took place on January 8, 2016, six months after his escape from Altiplano prison in Mexico. If the escape was spectacular-being from a high-security prison and evidencing collusion of authorities and corruption of the system-the recapture was even more so. Well-known figures, such as actors Kate del…
Cytotoxicity of tumor antigen specific human T cells is unimpaired by arginine depletion.
2013
Tumor-growth is often associated with the expansion of myeloid derived suppressor cells that lead to local or systemic arginine depletion via the enzyme arginase. It is generally assumed that this arginine deficiency induces a global shut-down of T cell activation with ensuing tumor immune escape. While the impact of arginine depletion on polyclonal T cell proliferation and cytokine secretion is well documented, its influence on chemotaxis, cytotoxicity and antigen specific activation of human T cells has not been demonstrated so far. We show here that chemotaxis and early calcium signaling of human T cells are unimpaired in the absence of arginine. We then analyzed CD8(+) T cell activation…
Size dependent carrier thermal escape and transfer in bimodally distributed self assembled InAs/GaAs quantum dots
2012
We have investigated the temperature dependent recombination dynamics in two bimodally distributed InAs self assembled quantum dots samples. A rate equations model has been implemented to investigate the thermally activated carrier escape mechanism which changes from exciton-like to uncorrelated electron and hole pairs as the quantum dot size varies. For the smaller dots, we find a hot exciton thermal escape process. We evaluated the thermal transfer process between quantum dots by the quantum dot density and carrier escape properties of both samples. © 2012 American Institute of Physics.
The red tooth hypothesis: A computational model of predator-prey relations, protean escape behavior and sexual reproduction
2009
This paper presents an extension of the Red Queen Hypothesis (hereafter, RQH) that we call the Red Tooth Hypothesis (RTH). This hypothesis suggests that predator-prey relations may play a role in the maintenance of sexual reproduction in many higher animals. RTH is based on an interaction between learning on the part of predators and evolution on the part of prey. We present a simple predator-prey computer simulation that illustrates the effects of this interaction. This simulation suggests that the optimal escape strategy from the prey's standpoint would be to have a small number of highly reflexive, largely innate (and, therefore, very fast) escape patterns, but that would also be unlearn…
ESCAPE TIMES IN STOCK MARKETS
2005
We study the statistical properties of escape times for stock price returns in the Wall Street market. In particular we get the escape time distribution for real data from daily transactions and for three models: (i) the Wiener process with drift and a constant market volatility, (ii) Heston and (iii) GARCH models, where the volatility is a stochastic process. We find that the first model is unable to catch all the features of the escape time distribution of real data. Moreover, the Heston model describes the probability density function for both return and escape times better than the GARCH model.
Effects of Emergence Time and Early Social Rearing Environment on Behaviour of Atlantic Salmon: Consequences for Juvenile Fitness and Smolt Migration
2015
Consistent individual differences in behaviour have been well documented in a variety of animal taxa, but surprisingly little is known about the fitness and life-history consequences of such individual variation. In wild salmonids, the timing of fry emergence from gravel spawning nests has been suggested to be coupled with individual behavioural traits. Here, we further investigate the link between timing of spawning nest emergence and behaviour of Atlantic salmon (Salmo salar), test effects of social rearing environment on behavioural traits in fish with different emergence times, and assess whether behavioural traits measured in the laboratory predict growth, survival, and migration statu…
Gabarap Loss Mediates Immune Escape in High Risk Multiple Myeloma
2021
Abstract Immune therapies including CAR T cells and bispecific T cell engagers are demonstrating remarkable efficacy in relapsed refractory myeloma (MM). In this context, we have recently shown that proteasome inhibitor bortezomib (BTZ) results in immunogenic cell death (ICD) and in a viral mimicry state in MM cells, allowing for immune recognition of tumor cells. Induction of a robust anti-MM immune response after BTZ was confirmed both in vitro and in vivo: treatment of 5TGM1 MM cells with BTZ induced tumor regression associated with memory immune response, confirmed by ELISPOT of mouse splenocytes. We have confirmed the obligate role of calreticulin (CALR) exposure in phagocytosis and th…
Gamificación en educación superior. Una escape room para el aula de matemáticas
2020
[ES] De unos años a esta parte, el perfil de nuestros estudiantes ha cambiado de manera considerable. Esto hace que, de manera complementaria a las clases magistrales, los profesores poco a poco debamos adaptarnos a las nuevas generaciones, mucho más tecnológicas que años atrás. Una de las maneras de aumentar la motivación y la participación de los estudiantes en nuestra asignatura es el planteamiento y la realización de diferentes actividades de manera que esto nos ayude también a desarrollar materiales que se adecuen al mayor número de alumnos posible. El objetivo general del presente artículo es utilizar la gamificación como herramienta docente en el aula. En concreto, proponemos el uso …
Escape room in education: a bibliometric study
2020
[EN] The impact of technologies in all areas is one of the main points that characterize the current society. In the educational context, recently, great efforts are being made to adapt the system to characteristics and needs of the students of the 21st century. Gamification in education consist on the use of structures, characteristics, dynamics and aesthetics of games for educational purposes, to increase students participation and motivation. The escape room is a gamified activity in which one or more teams must leave a place during a limited time solving a challenge whose goal is learning. This study pretends to analyze research trends through a bibliometric study of scientific producti…
