Did the recent transition to liberal democracy in Eastern Europe consitute revolutions? Here, game theory is used to structure an explanation of institutional change proposed by Harold Innis (1950).

Over the twentieth century, the allocation of womens' time changed dramatically. This paper explores the implications for the allocation of married womens' time stemming from: (1) the household revolution associated with the introduction of a variety of labor-saving devices in the home; (2) the remarkable increase in the relative wage of women; and (3) changes in childcare requirements associated with changes in fertility patterns. To do so, we construct a life-cycle model with home production and childcare constraints. The parameters of the childcare production function are estimated using micro evidence from U.S. time use data. We find that the increase in the relative wage of women is the most important explanation of the increase in married womens' market work time over the twentieth century. Changes in fertility had large effects up to 1980, but little effect thereafter. The declining price of durables has an appreciable effect only since 1980, an effect that is consistent with a broader interpretation of durable goods reflecting the marketization of home production.

The present thesis can be divided into three areas:1) the fabrication of a low temperature photo-luminescence and photoconductivity measuring unit 2) photo-luminescence in the chalcopyrite CulnSez and CulnS2 system for defect and composition analysis and 3) photo-luminescence and photo-conductivity of In:JS3. This thesis shows that photo-luminescence is one of most essential semiconductor characterization tool for a scientific group working on photovoltaics. Tools which can be robust, non-destructive, requiring minimal sample preparation for analysis and most informative of the device applications are sought after by industries and this thesis is towards establishing photo-luminescence as "THE" tool for semiconductor characterization. The possible application of photo-luminescence as a tool for compositional and quality analysis of semiconductor thin films has been worked upon by this thesis. Photo-conductivity complement photo-luminescence and together they provide all the information required for the fabrication of an opto-electronic device.

Tuesday 22nd April 2014 Speaker(s): Sue Sentance Organiser: Leslie Carr Time: 22/04/2014 15:00-16:00 Location: B32/3077 File size: 698 Mb Abstract Until recently, "computing" education in English schools mainly focused on developing general Digital Literacy and Microsoft Office skills. As of this September, a new curriculum comes into effect that provides a strong emphasis on computation and programming. This change has generated some controversy in the news media (4-year-olds being forced to learn coding! boss of the government’s coding education initiative cannot code shock horror!!!!) and also some concern in the teaching profession (how can we possibly teach programming when none of the teachers know how to program)? Dr Sue Sentance will explain the work of Computing At School, a part of the BCS Academy, in galvanising universities to help teachers learn programming and other computing skills. Come along and find out about the new English Computing Revolution - How will your children and your schools be affected? - How will our University intake change? How will our degrees have to change? - What is happening to the national perception of Computer Science?

Se examinan las malas condiciones de vida en las que se encontraba la población rusa a principios del siglo XX, y lo poco que el gobierno zarista hizo para mejorarlas. Se describen los acontecimientos que llevaron a los bolcheviques al poder en 1917 y cómo Lenin obtuvo el control del país, introdujo una nueva política económica y una nueva constitución. Incluye fragmentos de fuentes históricas originales, así como, material de aprendizaje activo: ejercicios, preguntas, y pruebas.

La evolución explica cómo llegamos a existir. Más de ciento cincuenta años más tarde de las teorías de Darwin, sus ideas se han hecho más convincentes, aunque siguen siendo controvertidas en algunas partes del mundo. Este conocimiento nos ayuda a comprender la enfermedad y la salud, nuestros instintos, emociones y, por encima de todo, a reconocer lo próximos que estamos de otros organismos vivos.
