We Act Therefore We Are: A Theory of Action Driven Strategy

This dissertation examines the effects of competitive actions on strategic choice. Despite acknowledging that competitive behavior might be an important determinant of organizational strategy, researchers in strategic management have yet to explore how competitive actions that firms adopt to acquire competitive advantage can also encourage future strategic decisions. Competitive actions can be sources of strategic choice because they expose the firm to its competitive environment. This exposure to the competitive environment generates salient experience and knowledge that narrow managerial selection of strategic alternatives, therefore influencing strategic choice.This dissertation develops a conceptual framework that links competitive dynamics to strategic choice literature and provides an empirical model grounded on observable and quantitative variables. Specifically, it tests how characteristics of competitive actions such as scope, and the use of action repertoires can directly influence strategic choices such as the adoption of diversification strategies, the divestment of assets, and the implementation of corporate social responsibility policies.Results confirm the theoretical prediction that competitive actions are drivers of strategic choice. I found support that characteristics of actions like breadth and the diversity of repertoires that firms adopt to compete are motivators of strategic choice. Such findings indicate that previously neglected connections between competitive behavior and strategy are relevant and indicative that firms' might access knowledge and experience previously obtained in the marketplace to decide which strategies to take.Business Administratio

“STOP MGF” programa de educación para la salud sobre prevención y detección de mutilación genital femenina

Se estima que la mutilación genital femenina (MGF) afecta a una población aproximada de más de 200 millones de mujeres y niñas residentes en 29 países de África, Oriente Medio y Asia. Es una vulneración de los derechos humanos de la mujer. La creciente incorporación a la sociedad española de familias procedentes de entornos geográficos, sociales y culturales donde la MGF tiene un fuerte arraigo identitario lleva a plantear que el profesional sanitario fomente el afrontamiento de nuevos retos asistenciales con el fin de favorecer una buena integración sociocultural.<br /

Classe Social na Creche

For much of contemporary sociology, the child is a social agent actively engaged in the production, appropriation and reproduction of culture. However, little is said about the way in which children participate in class reproduction. Relying on the observation of the routine of classes of two and three year-olds in a public and a private day care center, serving families from different social groups, the authors show how children actively contribute to shaping the educational experiences they are exposed to. Children from low income and less educated families exhibit greater autonomy, self-sufficiency and independence from adults, while children from middle upper class and more educated families are more demanding and disobedient. As a result, the latter receive more attention from adults. This contributes to a more significant differentiation in the pedagogical work in both spaces, adding a new dimension to the institutional differences despite the similarity they have in other respects (the wages of teachers and monitors, physical space, mentoring). These results show one of the dimensions by which class inequality is produced in education.Para gran parte de la sociología contemporánea, el niño es un agente social que participa activamente en la producción, apropiación y reproducción de la cultura. Sin embargo, poco se dice acerca de la forma en que los niños participan en la reproducción de la clase. Basándose en la observación de la rutina de las clases de niños de dos a tres años en una guardería pública y una privada, que atienden familias de grupos sociales diferentes, las autoras muestran como los niños contribuyen activamente para dar forma a las experiencias educativas a que son expuestos. Los niños de familias con ingresos bajos, menos educadas, exhiben una mayor autonomía, autosuficiencia e independencia de los adultos, mientras que los niños de familias de clase media alta, más educadas, son más exigentes y desobedientes. Como resultado, estos últimos reciben más atención de los adultos. Esto contribuye para una diferenciación significativa del trabajo pedagógico en los dos espacios, adicionando una nueva dimensión a las diferencias de contexto institucional a pesar de las similitudes que presentan en otros aspectos (sueldo de las maestras, espacio físico, orientación pedagógica). Estos resultados revelan, así, una de las dimensiones de los complejos procesos por los cuales se produce la desigualdad de clase en la educación.Para boa parte da sociologia contemporânea, a criança é um agente social ativamente engajado na produção, apropriação e reprodução da cultura.

Differences in spatio-temporal parameters between trained runners and untrained participants

24 p.El objetivo de este estudio fue comparar los parámetros espacio-temporales de corredores entrenados y participantes no entrenados, con el mismo patrón de golpe de pie (parte posterior del pie) durante la carrera en velocidades controladas. Veintiún participantes fueron clasificados en dos grupos de acuerdo a sus experiencia de entrenamiento. Las variables antropométricas fueron grabadas, y los participantes realizaron tanto sub-máximos (entre 9 y 15 km /h) como una prueba de carrera de ejercicio gradual (desde 6 km/h hasta agotamiento) en una cinta de correr. Las variables fisiológicas (VO2 máx., frecuencia cardíaca, economía de carrera, velocidad máxima ...) y biomecánicas (contacto y tiempos de vuelo, paso y duración) se registraron simultáneamente. Los corredores entrenados mostraron una frecuencia de pasos más alta y una longitud de pasos más corta que el grupo no entrenado en la misma ejecución de velocidades (entre 4-7%, p <0.05) y con las mismas intensidades fisiológicas (entre 7-11%, p <0,05). Sin embargo, no hubo diferencias en los tiempos de contacto y de vuelo entre los grupos. Las diferencias significativas (p <0,05) entre los grupos fueron evidentes en relación a la masa corporal, suma de 6 pliegues cutáneos, VO2 máx., velocidad pico y umbral ventilatorio. El grupo entrenado también mostró un ~ 7% de mejora en economía de carrera en relación al grupo no entrenadoS

SAVASA project @ TRECVID 2012: interactive surveillance event detection

In this paper we describe our participation in the interactive surveillance event detection task at TRECVid 2012. The system we developed was comprised of individual classifiers brought together behind a simple video search interface that enabled users to select relevant segments based on down~sampled animated gifs. Two types of user -- `experts' and `end users' -- performed the evaluations. Due to time constraints we focussed on three events -- ObjectPut, PersonRuns and Pointing -- and two of the five available cameras (1 and 3). Results from the interactive runs as well as discussion of the performance of the underlying retrospective classifiers are presented

PRODUCTION OF SEEDLINGS OF COLUBRINA GLANDULOSA PERKINS WITH DRILLING WASTE FROM OIL WELLS AND MYCORRHIZAL INOCULATION

Oil exploration, whether onshore or offshore, results in residues from the drilling of wells, called gravel. The use of this environmental liability in the production of seedlings for forest restoration could contribute to an appropriate destination for this waste. In the present study, the objective was to evaluate the effect of the substrate formulated with gravel, with and without inoculation with arbuscular mycorrhizal fungi (AMF), on the growth and nutritional status of seedlings of Colubrina glandulosa. The design used was completely randomized in a 5x2 factorial scheme, with five gravel doses (0, 5, 10, 15, and 20%), with and without inoculation with a mixture of AMF spores (Gigaspora margarita¸ Rhizophagus clarus, and Dentiscutata heterogama) with six repetitions, totaling 60 experimental units. Height (H) and stem diameter (SD) were evaluated at 30, 60, 90, and 120 days after seedling transplantation, when the plants were sectioned in shoots (branches + leaves) and roots, to determine dry biomass of shoots (DMS) and of roots (DMR), leaf area index (LAI), rate of length of fine roots colonized by AMF (COL), and chemical composition. The substrate obtained with the application of the lowest gravel dose (5%), without the mycorrhizal inoculation, provided significant increments in H, SD, LAI, DMS, DMR, and COL of the seedlings of Colubrina glandulosa, when compared to the other gravel doses and the presence of mycorrhizal inoculation, 120 days after seedling transplantation
