To understand the broadcast segments of multi‐industry companies, it is important to consider the revenue demands of their parent companies. This article develops a methodology for analyzing the profitability of broadcast and non‐broadcast segments and applies that methodology in an examination of publicly held corporations. 相似文献

The logic of political economy depends on a domestic metaphor, using the oikos or household as a model for the polis. Historically, this metaphor has imagined citizens as the children of a paternal state. However during the 2008 housing crisis, this metaphor was turned upside down, depicting citizens as the parents of infantile state institutions. Although initially portraying citizens as juvenile “delinquents,” the rhetoric of the mortgage crisis ultimately repositioned citizens as surrogate caretakers for Fannie Mae and Freddie Mac, the two giant politico-economic institutions that constituted the majority of the mortgage market. In this way, the rhetoric of the housing crisis inverted both the metaphorical and material structure of political economy. 相似文献

RESUMENSe describe un programa de estimulación precoz llevado a cabo en un centro de educación especial, programa que se marcó dos objetivos principales: ofrecer al niño un ambiente rico en estímulos y mejorar la relación afectiva de los padres. El diagnóstico se hace a través de un enfoque multidisciplinar y se trabaja en cuatro áreas: desarrollo personal, control motor grueso, control motor fino y lenguaje. Es muy importante integrar a los padres en el programa educativo, ya que son los principales agentes educativos. En este sentido se trabaja a nivel tanto informativo (de forma individual y con sesiones programadas en la Escuela de Padres) como formativo (asesoramiento familiar individual). 相似文献

ResumenSe han aplicado dos pruebas de palabras reales y palabras artificiales (semejante a la de Berko, 1958) a 109 niños hispano-parlantes de tres a seis años de edad, a fin de establecer la evolución en el uso de morfemas de plural, aumentativos y diminutivos, gerundio, pretérito imperfecto de indicativo y pretérito indefinido. Los resultados indican un progreso importante entre los tres y los cuatro años, siendo la curva posterior del desarrollo más suave. Se establece un orden de dificultad de estos morfemas, y se realiza un análisis de los errores cometidos, encontrándose también sobrerregularizaciones con verbos reales irregulares. Se extraen implicaciones acerca del proceso de adquisición de morfemas. 相似文献

ResumenEl propósito de este estudio fue diseñar un modelo válido para la adquisición de unos adecuados hábitos de estudio, basado en una combinación de estrategias de autorregulación y técnicas de estudio. Se procedió mediante un diseño exploratorio de línea de base múltiple, con un único sujeto que incluía: a) fase de pretest, b) primera fase de intervención, en la que se introdujeron las estrategias de autorregulación, c) segunda fase de intervención o de introducción de las técnicas de estudio, y d) fase de postest. El resultado fue un cambio experimental y terapéuticamente significativo en los hábitos de estudio y en las conductas exponentes de: tiempo de estudio, desatención, y velocidad y comprensión lectoras, las calificaciones experimentaron un ascenso progresivo. Estos cambios se mantuvieron y consolidaron en el seguimiento, las estrategias de autorregulación se han mostrado útiles para aumentar la probabilidad de ocurrencia de la conducta deseada y disminuir la de la no deseada. 相似文献

AbstractIn order to design prevention programs, it is important to understand the evolution of drinking behaviour patterns among adolescents and young people. The aim of this paper is to analyse the changes in these patterns based on age and their role in explaining this behaviour in the Theory of Planned Behaviour framework. We used 273 participants divided into three sub-samples (3rd and 4th ESO [Educación Secundaria Obligatoria, ‘Compulsory Secondary Education’] students and university students). For older ages, the frequency of binge drinking is higher and the attitudes were also more positive towards alcohol consumption. Structural equation analyses show that drinking behaviour is explained by a different model in each age-group: in older groups, the role played by positive attitude and perceived control is more important than in the younger; by contrast, the influence of reference groups decreases with age. Results show significant differences between age groups regarding the reasons that young people report for engaging or not engaging in this behaviour. 相似文献

Synchronous collaborative information retrieval (SCIR) is concerned with supporting two or more users who search together at the same time in order to satisfy a shared information need. SCIR systems represent a paradigmatic shift in the way we view information retrieval, moving from an individual to a group process and as such the development of novel IR techniques is needed to support this. In this article we present what we believe are two key concepts for the development of effective SCIR namely division of labour (DoL) and sharing of knowledge (SoK). Together these concepts enable coordinated SCIR such that redundancy across group members is reduced whilst enabling each group member to benefit from the discoveries of their collaborators. In this article we outline techniques from state-of-the-art SCIR systems which support these two concepts, primarily through the provision of awareness widgets. We then outline some of our own work into system-mediated techniques for division of labour and sharing of knowledge in SCIR. Finally we conclude with a discussion on some possible future trends for these two coordination techniques. 相似文献

One of the benefits claimed for investment in Research and Development (R&D) is that there is a spillover effect. Industries benefit from both their own R&D efforts as well as the efforts of other national and overseas industries. The present research presents new evidence on the long-term impact of R&D investment upon UK industry's productivity performance and on the nature of these “R&D spillovers”. The results suggest that R&D efforts from the industry itself and from other national industries have a positive impact on the industry's productivity but, interestingly, there is no gain from foreign R&D investment. 相似文献
