A Dynamic Analysis of Household Decision-Making in Urban Colombia, 1976-1998: Changes in Household Structure, Human Capital and its Returns, and Female Labor Force Participation

The objective of this paper is to examine the changes and dynamics of household structure, human capital and the returns to education, labor earnings, women’s labor force participation and investment in human capital. The approach used in the analysis is the so-called "cohort technique," which consists of following across time men and women born in the same year or year spell. The main sources of information for this work are the quarterly Household Surveys beginning in 1976. With such information a database of more than 6 million observations (workers, parents, children, etc. ) was constructed. The research results show that the number of children of the younger parents has drastically decreased. This process has been accompanied by a significant increase in women’s labor force participation and higher women’s school attainment. The study also points out that the school attainment of the younger generation of women is higher than men’s and that the income gap between men and women of the new generation, after controlling for education, is lower than the gap in older generations. Finally, the study indicates that human capital accumulation has been very unequal for different income groups. The children of low educated parents achieve low levels of education both in old and new generations. Thus, escaping from the poverty trap is as difficult today as in the past, as education opportunities are concentrated in the middle and high-income groups.

Making Managerial Decisions To Solve The Deficit Of Filling Materials During The Construction Of Structures At A Hydroelectric Project

En el presente trabajo de investigación se presentan los resultados y conclusiones obtenidas de una metodología gerencial combinada cualitativa y cuantitativa, aplicadas a una problemática técnica, identificada en la etapa de Construcción de un proyecto Hidroeléctrico. La problemática surge en la identificación de un déficit importante de material apto para construir los rellenos de las estructuras principales que funcionaran como contención del embalse de agua, el cual simultáneamente servirá para generar energía Eléctrica. La metodología se basa en tomar una serie de decisiones gerenciales necesarias para contrarestar el déficit de material apto para el relleno de las mencionadas estructuras.This research report presents the results and conclusions obtained from a qualitative and quantitative analysis applied to a technical problem, which was identified throughout the construction process of a hydroelectric project. The problem arises with the detection of a significant shortage of suitable materials for the construction of water containment structures, which are designed to create an embankment of water used for electricity generation. The methodology applied consists of taking a series of management decisions needed to counteract the shortage of suitable materials for the completion of the aforementioned structures

Institutional Policies, Secondary School Quality and Teacher Effects: Three Studies on Inequality of Educational Opportunity in Chile

Inequality of educational opportunity is a crucial topic in education policy, and a matter of strong debate in the Chilean context. In this thesis, I aim to identify and analyse likely drivers of educational inequality in Chile, by looking at three relevant dimensions: Teacher effectiveness, Secondary School Quality and School Systems’ Institutional Characteristics. First, in Chapter 2, I analyse how differentials on teacher effectiveness across Chilean schools from different socioeconomic status explain differentials in learning achievement in secondary education. Second, in Chapter 3, I assess how school level characteristics and other institutional features of the Chilean school system could be explaining students’ access to higher education. Third, in Chapter 4, and through an international comparison using PISA data, I study the effect of school accountability practices on educational outcomes, gathering lessons for the Chilean case

Conflicto lingüístico y separatismo en Canadá

Este artículo analiza la historia del conflicto lingüístico entre el pueblo francófono y el pueblo anglófono dentro de la doble realidad cultural de Canadá y muestra el imperialismo inglés hacia el pueblo québécois a lo largo de su historia. Con respecto a la posible independencia de Quebec, el artículo habla a favor de un Canadá unido sin miedo de ofender a los québécois. Y se desprenden dos conclusiones: una emocional y otra racional. La emocional nos recuerda las palabras del profesor Russell: “Amo a Canadá”, “Canadá es un gran país”. En la racional se nos recuerda las trágicas consecuencias de la desintegración de imperios y naciones. Y se afirma que los québécois no van a vivir mejor si se separan del resto de Canadá. Lo que se necesita verdaderamente es un federalismo más interactivo y más económicamente independiente de los Estados Unidos. This article examines the history of the linguistic conflict between Francophones and Anglophones within the double cultural reality of Canada and shows the English imperialism towards the Quebecois throughout their history. With regard to the possible independence of Quebec, the article discusses Canadian unity without fear of offending the Quebecois. Two conclusions stand out: one emotional and another rational. The emotional one reminds us of Professor Russell’s words: “I love Canada”, “Canada is a great place”. The rational conclusion reminds us of the tragic consequences of the disintegration of empires and nations. It is asserted that the Quebecois will not live better if they separate from the rest of Canada. What the country really needs is a federalism, more interactive and more economically independent from the United States

The Rejection of Falstaff.

This article discusses the rejection of Falstaff comparing Act 5, scene 5 of 2 Henry IV, with Act 1, scene 2 of 1 Henry IV. The rejection is inevitable because Falstaff represents disorder. His triumph would mean the victory of anarchy over order, stability and justice. But we become so involved with him that we even tolerate his conspiracies. He is clever, funny and one of the most fascinating characters in English literature. The two plays show the Prince as a good student of Machiavelli; we could consider them as a practical guide to instruct the Prince in his road to power

Delay effects on the limit cycling behavior in an H-bridge resonant inverter with zero current switching control strategy

Celebrado en Tarragona del 2-6 de septiembre de 2018.In this paper, bifurcations of limit cycles in a H-bridge LC resonant inverter under a zero current switching control strategy with delay in the switching action are analyzed. Mathematical analysis and numerical simulations show that the delay can degrade the quality of the oscillations and even inhibit them.Agencia Estatal de Investigación DPI2017- 84572-C2-1-RFondo Europeo de Desarrollo Regional DPI2017- 84572-C2-1-RMinisterio de Ciencia e Innovación MTM2015-65608-PJunta de Andalucía Consejería de Economía y Conocimiento P12-FQM-165
