    En este artículo se presenta una revisión de la literatura en torno al liderazgo transformacional, la cultura organizacional y el cambio educativo. A partir de ella, se hace una reflexión sobre la vinculación que existe entre los tres elementos y la potencial interdependencia que ostentan en el contexto escolar. Para ello, en la primera sección, se sintetizan las teorías clásicas que contribuyeron a la construcción del concepto del liderazgo transformacional y el proceso que se siguió para la consolidación del mismo, a través de lo cual se enfatizan los elementos fundamentales de este tipo de líder y sus diferencias con el transaccional. En la segunda sección, se analiza el rol del líder transformacional en el contexto organizacional en un ambiente de cambio educativo; en ella, se destaca el papel que desempeña el líder transformacional en las instituciones educativas y se vincula con la cultura organizacional como un elemento contextual que eventualmente es interdependiente con este tipo de liderazgo. Finalmente se hace una reflexión sobre el estado del arte de la vinculación entre los tres constructos presentados y se proponen líneas potenciales de investigación que pueden contribuir al mayor conocimiento sobre la complejidad de la relación entre ell

    The influence of traditional and non-traditional educational models on children’s beliefs towards education, future expectations and resilient attitudes

    Education is considered as a protective and empowering tool against social problems. Recent studies have directed their attention to non-traditional methods of education due to their influence in positive academic and personal outcomes. In Uganda, the country where this study has been conducted, the education system has remained that which was introduced under the colonial era, predominantly the traditional model. Therefore, few schools -particularly those following international curriculums-, are promoting a non-traditional educational model, with emphasis on the child’s holistic development including focus on social skills and knowledge application abilities. The present research aimed to compare possible influences of traditional and non-traditional educational models on children’s beliefs towards education and its potential relation with their present life perceptions, future expectations and resilient attitudes. A cross-sectional and comparative case study research design was thus adopted using qualitative research methods mainly guided by grounded theory principles. Overall, eighteen children and three teachers from three different sets of schools - a public, private and an international- in Kampala district, participated in the study which was undertaken between February and March 2015. The main results indicate that there is a positive influence on learner’s perceptions and beliefs towards education within the educational model that they were under. Children’s attitudes and perceptions about education and learning favoured the model in which they were immersed and preferred the academic activities of each system because of their relation with the important elements promoted in each model. Also, children in traditional model seem to have more certainty about their future accomplishment, but the ones in non-traditional settings show a deeper reflective process towards their future. The economic status of children’s families –instead of the educational model- emerged as a factor related to how children perceived their present life and their future aspirations. Using a social constructivist and ecological perspective which emphasize the importance of the environment, study concludes by affirming a difference in how educational models can foster resilient attitudes. Non- traditional models are more likely to promote a growing mindset and resilient attitudes as opposed to traditional models which focusing on the academic excellence of the child almost exclusively, tend to promote fixed mindset and offer fewer opportunities to develop resilient attitudes. Recommendations point to changes on educational policies and interventions including teacher training on effective praising and innovative ways of promoting and integrating critical thinking in academics

    Applications of Personal Computer Presentations For Corporate Video Users

    This thesis is a study of desktop video as an application to the traditional postproduction process utilized by corporate video producers. Desktop video involves the personal computer in the editing process; this definition includes the personal computer as an editing and special effects tool. The purpose of this study is to measure the feelings and attitudes of professionals in the field of video postproduction about desktop video and its application to traditional methods of editing. The introduction of new technology inevitably leads to a period which the new technology is opposed by those who understand and are comfortable with the traditional modes of operation. The goal is to find out whether the desktop video technology is a threat to tradition, whether it is being accepted in everyday use by businesses who utilize industrial videos, or if the application of desktop video will lead to the opening of new markets. The promise of desktop video production is that it is cheaper than traditional processes, enabling industrial users to expand their usage and the markets they can afford to approach. This qualitative focus group study was conducted with members of the International Television Association (ITVA) chapter located in Knoxville, Tennessee. The study involved the presentation of a 10 minute video, prepared by one person, which showed what the desktop presentation technology could do and its application to the corporate user. A group discussion followed the showing of the video, using a set of questions designed to elicit responses to the presentation and the field of desktop video in general. Next, a demographic questionnaire and a Likert Scale questionnaire were distributed with questions about desktop video and its application to the corporate video user. Responses from strongly agree to strongly disagree were used to create a quantitative means of comparison for this study. The results of this focus group study showed a variety of feelings and attitudes concerning the use of personal computers in the postproduction process. The majority of the professionals were familiar with the new technology, but felt that it only applied to those high-end professionals who knew how to use the present equipment. The group agreed that applications for the individual user were limited, that the learning curve for personal computers was a deterrent for anyone to simply pick up a personal computer and instantly become an expert in postproduction editing. The general feeling of this group was that personal computers were an asset to the professional, but that the postproduction process was still one where trained personnel could best handle the job, with or without a computer. The findings of this study point out an inherent weakness of the application of the personal computer to the traditional postproduction process. Working within the constraints of magnetic tape, an analog method of storing information, limits the computer to working within a system which it cannot simply optimize by becoming a part of it. For the desktop video use to create a difference, a change will have to come in the method of storing and recording video information. This study includes brief glimpses at the future of video, moving from magnetic tape to the compact disc and other digitally oriented modes of video production. In order for desktop video to make a difference, the postproduction reliance on magnetic tape must be changed, for then a computer may enhance the process by working with digital devices instead of analog tape

    Electron dynamics in complex time and complex space

    This thesis investigates the dynamics of electrons ionized by strong low frequency laser fields, from a semiclassical perspective, developing a trajectory-based formalism to describe the interactions of the outgoing electron with the remaining ion. Trajectory models for photoionization generally arise in the regime known as optical tunnelling, where the atom is subjected to a strong, slow field, which tilts the potential landscape around the ion, forming a potential energy barrier that electrons can then tunnel through. There are multiple approaches that enable the description of the ionized electron, but they are generally limited or models derived by analogy, and the status of the trajectories is unclear. This thesis analyses this trajectory language in the context of the Analytical R-Matrix theory of photoionization, deriving a trajectory model from the fundamentals, and showing that this requires both the time and the position of the trajectory to be complex. I analyse this complex component of the position and I show that it requires careful handling: of the potentials where it appears, and of the paths in the complex plane that the trajectory is taken through. In this connection, I show that the Coulomb potential of the ion induces branch cuts in the complex time plane that the integration path needs to avoid, and I show how to navigate these branch cuts. I then use this formalism to uncover a kinematic mechanism for the recently discovered (Near-)Zero Energy Structures of above-threshold ionization. In addition, I analyse the generation of high-order harmonics of the driving laser that are emitted when the photoelectron recollides with the ion, using a pair of counter-rotating circularly polarized pulses to drive the emission, both in the context of the conservation of spin angular momentum and as a probe of the long-wavelength breakdown of the dipole approximation.Open Acces

    El carácter evolutivo de las prácticas sociales. El caso de la predicción

    Get PDF
    Este escrito reporta los resultados de una investigación de tipo histórico epistemológico acerca del carácter evolutivo de las prácticas sociales, constructo teórico fundamental en la aproximación socioepistemológica a la investigación en Matemática Educativa. En particular esta investigación analiza, cómo se concibe a la predicción desde la Socioepistemología y hace un recorrido histórico conceptual alrededor de la génesis y el posterior desarrollo de los fractales. Una comparación de estos dos análisis nos hace concluir que todo el conocimiento, las herramientas y la teoría creados en torno a los fractales fueron guiados por la práctica social de la predicción. Se muestra así una evolución de la práctica social de la predicción caracterizándola en predicción determinista y predicción no determinista
