Towards Learning âSelfâ and Emotional Knowledge in Social and Cultural Human-Agent Interactions
Original article can be found at: http://www.igi-global.com/articles/details.asp?ID=35052 Copyright IGI. Posted by permission of the publisher.This article presents research towards the development of a virtual learning environment (VLE) inhabited by intelligent virtual agents (IVAs) and modeling a scenario of inter-cultural interactions. The ultimate aim of this VLE is to allow users to reflect upon and learn about intercultural communication and collaboration. Rather than predefining the interactions among the virtual agents and scripting the possible interactions afforded by this environment, we pursue a bottomup approach whereby inter-cultural communication emerges from interactions with and among autonomous agents and the user(s). The intelligent virtual agents that are inhabiting this environment are expected to be able to broaden their knowledge about the world and other agents, which may be of different cultural backgrounds, through interactions. This work is part of a collaborative effort within a European research project called eCIRCUS. Specifically, this article focuses on our continuing research concerned with emotional knowledge learning in autobiographic social agents.Peer reviewe
Anisotropic Superconductivity in the Induced Pairing Model
The model of local electron pairs and itinerant fermions coupled via charge
exchange mechanism, which mutually induces superconductivity in both subsystems
is studied for anisotropic pairing symmetry. The phase diagram is presented and
the phase fluctuations effects are analyzed within the Kosterlitz-Thouless
scenario.Comment: 4 pages, 2 figures. Physica B (in press), Proceedings of the

Para ilustrar la estructura, el rendimiento y los riesgos que involucran estos productos, se aplica un m?todo de simulaci?n Monte Carlo a trav?s del lenguaje de programaci?n de c?digo abierto Python
Innovation and Entrepreneurship in the Hospitality Industry
Which hotels benefit from locating next to competitors? In this study of 14,995 hotels we provide evidence of both a price benefit and a detriment for specific hotels that coâlocate next to other hotels. Relying on the theoretical framework of agglomeration economics, the results reveal that hotels that coâlocate in the same geographic cluster with the highest quality segmented firms (luxury hotels) accrue a price premium compared to competitors in markets with larger proportions of lowerâsegmented competitors. The strongest price premiums were obtained by midscale hotels without food and beverage in clusters with large proportions of luxury and upscale hotels. Similarly, highâend hotels that pursue differentiation strategies experience price erosion when they are in the same geographic location as lowerâend hotels. Luxury hotels experienced the greatest price erosion when they operate in locations with large proportions of economy and midscale hotels. The paper concludes with a discussion of the implications of these findings for competitive dynamics and hotel location decisions
The Role of Emotions in Service Encounters
This article advances our understanding of the influence of affect in consumersâ responses to brief, non-personal service encounters. This study contributes to the services marketing literature by examining for mundane service transactions the impact of customer-displayed emotion and affect on assessments of the service encounter and the overall experience. Observational and perceptual data from customers were matched with frontline employees in 200 transaction-specific encounters. The results of this study suggest that consumersâ evaluations of the service encounter correlate highly with their displayed emotions during the interaction and post-encounter mood states. Finally, the findings indicate that frontline employeesâ perceptions of the encounter are not aligned with those of their customers. The managerial implications of these findings are briefly discussed

Diagn?stico de h?bitos lectores y apoyo familiar en h?bitos lectores en estudiantes de primero de primaria
161 p. Recurso Electr?nicoDentro del desarrollo integral de los estudiantes el componente de lenguaje es un ?rea
fundamental. En el caso de los estudiantes de primero de primaria las competencias
lectoras y escritoras son el eje principal de su formaci?n. En la Instituci?n Educativa San
Luis Gonzaga sede 02 Carolita, existen desempe?os pobres en las competencias
lectoras, medidos por las pruebas SABER 3, y reconocidos a trav?s de la observaci?n
por los docentes. Se estableci? como prop?sito central de este trabajo realizar un
diagn?stico de los h?bitos lectores y el apoyo familiar en dichos h?bitos, de los
estudiantes de primero de primaria y sus acudientes de la Instituci?n Educativa San Luis
Gonzaga sede 02 Carolita. Se plante? un estudio de enfoque mixto (cualitativocuantitativo),
de tipo descriptivo y de corte transversal. Participaron 18 estudiantes de
primero de primaria del a?o 2018 de la Instituci?n Educativa San Luis Gonzaga sede 02
Carolita, una docente siendo directora del grupo de estudiantes de primero de primaria.
La recolecci?n de informaci?n se realiz? con la aplicaci?n de los cuestionarios:
caracterizaci?n del grupo familiar, calidad del entorno de desarrollo, encuesta de
diagn?stico de h?bitos lectores para estudiantes de grado primero, y una entrevista
dirigida a la docente y directora del grupo de primero de primaria de la Instituci?n
Educativa. Como principales hallazgos se destacan: se encontraron h?bitos lectores
nulos y bajos, como falta de acompa?amiento de los padres de familia. Es necesario,
que se cree un mecanismo que incremente el apoyo y acompa?amiento de los padres
en el establecimiento de h?bitos lectores en los estudiantes de primero de primaria de la
Instituci?n educativa.
Palabras clave: H?bitos lectores, Diagn?stico, Apoyo familiar, Infancia.The development of students with a view to integral education, the importance of
acquiring competences in different areas of knowledge is recognized; and language is
fundamental. For students in first-year of school, reading and writing skills are one of the
main axis of their training. At the Instituci?n Educativa San Luis Gonzaga, Sede 02
Carolita, there are poor performances in it, measured by the SABER 3 tests. It also was
recognized by direct observation by professors and in personal conversations with their
teachers. In this sense, it was established as central to diagnose reading habits and family
support in these habits for first year students and their parents. A mixed approach
(qualitative-quantitative), descriptive and cross-sectional study was proposed. All first
grade students from the institutions in 2018 participated, 18 in total, their teacher and their
families. The data collection was carried out through the questionnaires: characterization
of the family group; quality of the development environment; diagnostic survey of reading
habits and parent support; and through an interview with the main teacher of students of
fist grade. As main findings it was noted that there were null and low reading habits and
lack of accompaniment and support from parents. It is necessary to establish actions from
the school that involve the family, the different actors from the school and the children as
a mechanism to increase the reading habits and the support and accompaniment in this
process for first grade students.

Agglomeration Effects and Strategic Orientations: Evidence from the U.S. Lodging Industry
This study provides evidence regarding the strategic dynamics of competitive clusters. Firms that agglomerate (co-locate) may benefit from the differentiation of competitors without making similar differentiating investments themselves. Alternatively, co-locating with a high percentage of firms with low-cost strategic orientations reduces performance for firms pursuing high levels of differentiation. Further, the lowest-cost providers with the greatest strategic distance from the norm of the competitive cluster reap the greatest benefit from co-location with differentiated firms. We find empirical support for these ideas using a sample of 14,995 U.S. lodging establishments, and controlling for a number of key demand-shaping factors
Phase transition between quantum and classical regimes for the escape rate of a biaxial spin system
Employing the method of mapping the spin problem onto a particle one, we have
derived the particle Hamiltonian for a biaxial spin system with a transverse or
longitudinal magnetic field. Using the Hamiltonian and introducing the
parameter where (U_{min})
corresponds to the top (bottom) of the potential and is the energy of the
particle, we have studied the first- or second-order transition around the
crossover temperature between thermal and quantum regimes for the escape rate,
depending on the anisotropy constant and the external magnetic field. It is
shown that the phase boundary separating the first- and second-order transition
and its crossover temperature are greatly influenced by the transverse
anisotropy constant as well as the transverse or longitudinal magnetic field.Comment: 5 pages + 3 figures, to be published in Phys. Rev.
