The Teaching of English Vocabulary through the Multisensory Approach to Older Adults in a Private Nursing Home in Pereira, Colombia
El siguiente documento es un proyecto de investigación cualitativo cuyo objetivo es integrar la teorÃa andragógica y el enfoque multisensorial para facilitar el aprendizaje de vocabulario en inglés a adultos mayores. Adicionalmente, este estudio es una iniciativa para incluir a los adultos mayores en un proceso de educación bilingüe ya que esta población casi no ha sido tomada en cuenta para la realización de proyectos bilingües. Por esta razón, este proyecto propone nuevas oportunidades para futuras investigaciones El presente estudio fue implementado en el hogar del anciano Casa Santa MarÃa en Pereira, Colombia. Este proyecto fue llevado a cabo en 10 clases en las cuales las participantes aprendieron 47 palabras relacionadas con su contexto inmediato. Las participantes del proyecto fueron cuatro mujeres, quienes tenÃan más de 60 años de edad. Las cuatro fueron consideradas como un proceso de muestreo tÃpico intencional para recopilar los datos, los cuales fueron interpretados por los investigadores. Además, durante la implementación del estudio, tres métodos de recolección de datos fueron empleados: observaciones, diarios de campo, y entrevistas. Los datos recogidos fueron analizados aplicando la teorÃa fundada, y después de este análisis los datos sugirieron que a) las estrategias de aprendizaje autodirigido pueden facilitar el éxito del aprendizaje de vocabulario y b) los sentidos de los adultos mayores tienen diferentes usos dependiendo de la etapa de la clase. Para concluir, el enfoque multisensorial es efectivo para enseñar vocabulario en inglés a adultos mayores junto con los principios andragógicos
Academic achievement in sciences: the role of preferences and educative assets
This paper provides new evidence on the effect of pupil´s self-motivation andacademic assets allocation on the academic achievement in sciences acrosscountries. By using the Programme for International Student Assessment 2006 (PISA2006) test we find that both explanatory variables have a positive effect onstudent´s performance. Self-motivation is measured through an instrumentthat allows us to avoid possible endogeneity problems. Quantile regression isused for analyzing the existence of different estimated coefficients over thedistribution. It is found that both variables have different effect on academicperformance depending on the pupil´s score. These findings support theimportance of designing focalized programs for different populations,especially in terms of access to information and communication technologiessuch as internet.PISA, self-motivation, academic assets, academic achievement, Quantile regression
The role of the mentor in the introduction of new principals: Contributions from research in a chilean ase
Se entregan los resultados de la evaluación de la implementación de un Programa de
Inducción de Directores nóveles de establecimientos públicos chilenos. EspecÃficamente, se
analizó el rol del mentor de estos directores, que es nuevo en el sistema educativo chileno,
para identificar qué tipos de efectos se reconocen como generados por la relación entre
mentor y director y su aporte a los objetivos del programa. Dentro de una evaluación
positiva del programa, se destaca el aporte principal de la mentorÃa en el desarrollo de
procesos reflexivos en torno al rol del director. Asimismo, se destaca la necesidad de que,
en el marco de esta relación, se desarrollen además aspectos que ayuden al conocimiento de
normativas, polÃticas educacionales o formas de trabajo en la escuela, asà como que se
desarrollen habilidades directivas, de liderazgo o toma de decisionesIn this paper, the results of the evaluation of the implementation of an Induction Program
of new directors of Chilean public establishments are delivered. Specifically, the role of the
mentor of these directors, who is new to the Chilean educational system, was analyzed to
identify which types of effects are recognized as generated by the relationship between
mentor and director and their contribution to the objectives of the program. Within a
positive evaluation of the program, the main contribution of mentoring in the development
of reflexive processes around the role of the director is highlighted. Likewise, the
participants emphasized that, within this relationship, help is needed in the knowledge of
regulations, educational policies or forms of work in the school, as well as the development
of managerial, leadership or decision-making skill
Jets from massive protostars as gamma-ray sources: the case of IRAS 18162-2048
Protostellar jets are present in the later stages of the stellarformation. Non-thermal radio emission has been detected from the jetsand hot spots of some massive protostars, indicating the presence ofrelativistic electrons there. We are interested in exploring if thesenon-thermal particles can emit also at γ-rays. In the presentcontribution we model the non-thermal emission produced in the jetsassociated with the massive protostar IRAS 18162-2048. We obtain thatthe γ-ray emission produced in this source is detectable by thecurrent facilities in the GeV domain.Fil: Araudo, Anabella Teresa. Provincia de Buenos Aires. Gobernación.

Impact of Organizational Culture Values on Organizational Agility
To remain competitive within the current, uncertain business scenario, it is vital for
firms to develop capabilities that lead them to adapt and offer quick responses to market changes.
Under the dynamic capabilities view of the firm, this paper proposes a model that presents an
exhaustive analysis of two relevant research gaps: (i) the underlying relationships that determine
the impact exerted by each of the four organizational culture typologies, comprised in Cameron
and Quinn’s Competing Values Framework on organizational agility and, (ii) the contingency
effect exerted by a key environmental factor, the industry’s technology intensity. An empirical
study is performed to test the relationships proposed, using data collected from 172 Spain-based
companies. To examine the contingency effect of technology intensity, the sample is divided into two
subsamples, high and medium tech companies. This work uses partial least squares path-modeling,
a variance-based structural equations modeling technique, in order to test and validate the research
model and hypotheses posited. In addition, thorough analyses are carried out to assess the predictive
performance of our modelJunta de AndalucÃa P10-SEJ-608
Light-harvesting in bacteria exploits a critical interplay between transport and trapping dynamics
Light-harvesting bacteria Rhodospirillum Photometricum were recently found to
adopt strikingly different architectures depending on illumination conditions.
We present analytic and numerical calculations which explain this observation
by quantifying a dynamical interplay between excitation transfer kinetics and
reaction center cycling. High light-intensity membranes (HLIM) exploit
dissipation as a photo-protective mechanism, thereby safeguarding a steady
supply of chemical energy, while low light-intensity membranes (LLIM)
efficiently process unused illumination intensity by channelling it to open
reaction centers. More generally, our analysis elucidates and quantifies the
trade-offs in natural network design for solar energy conversion.Comment: 4 pages and 4 figures. Accepted for publication in Physical Review

Information systems capabilities and organizational agility: Understanding the mediating role of absorptive capacity when influenced by a hierarchy culture
Organizational agility (OA), as a key dynamic capability, is a firm’s ability to enable sensing
environmental changes and responding efficiently and effectively to them. This study
explores this topic further by analyzing the part played by the information systems
capabilities (ISC) variable as an antecedent of OA, and absorptive capacity (AC) as a
mediator construct. Furthermore, we test the negative moderating role of hierarchy culture
(HC) in the AC–OA link. Using partial least squares (PLS) and the PROCESS macro, we find
evidence of these relations proposed, and the existence of a conditional mediating situation
generated by H
