Poverty and children's work in Spain and Latin America. Some preliminary remarks.

In the first part of this paper we try to test the relationship between mothers earnings, fertility and children's work in the Spanish (Catalan) context of the first third of the 20th century. Specific human capital investment of adult working women had as an outcome the sharp increase of their real wage and also the increase of the opportunity cost of time devoted to house work including child rearing. Fertility evolution is endogenous to the model and decreases as a result of women real wage increases. Human capital investment of labouring women and mandatory schooling of children shift the labour supply function to a new steady state in which the slope is steeper. According to recent papers this model applies to 20th century Spain and it causes the abolition of children's work. Nonetheless the model do not apply to 20th century Latin America. Despite the positive evolution of literacy and life expectancy in this region, other factors involved poor results of the educational human capital investment. In this paper we remark the role of the increasing share of the informal sector of the economy ruled on the bases of women's and children's work. Second we stress the role of high income inequality evolution and endogamic school supplies to explain the limits of increasing literacy on more remarkable human capital improvements.

The Sustainable Debts of Philip II: A Reconstruction of Spain's Fiscal Position, 1560-1598

The defaults of Philip II have attained mythical status as the origin of sovereign debt crises. Four times during his reign the king failed to honor his debts and had to renegotiate borrowing contracts. In this paper, we reassess the fiscal position of Habsburg Spain. New archival evidence allows us to derive comprehensive estimates of debt and revenue. These show that primary surpluses were sufficient to make the king's debt sustainable in most scenarios. Spain's debt burden was manageable up to the 1580s, and its fiscal position only deteriorated for good after the defeat of the "Invincible Armada." We also estimate fiscal policy reaction functions, and show that Spain under the Habsburgs was at least as "responsible" as the US in the 20th century or as Britain in the 18th century. Our results suggest that the outcome of uncertain events such as wars may influence on a history of default more than strict adherence to fiscal rules.

What do women do? World population growth and fertility patterns, 1960-2000

In this paper we attempt to describe the general picture reasons behind the world population explosion during the 20th century. In general we comment that if, according to some, at the end of the 20th century there were too many people, this was has a consequence of scientific innovation, circulation of information, and economic growth, leading to a dramatic improvement in life expectancies. Nevertheless, a crucial variable shaping differences in demographic growth is fertility. In this paper we identify as important exogenous variables affecting fertility female education levels, infant mortality, and racial identity and diversity. It is estimated that three additional years of schooling for mothers leads on average (at the world level ) to one child less per couple. Even if we can identify a worldwide trend towards convergence in demographic trends, the African case needs to be given more attention, not only because of its different demographic patterns, but also because this is the continent where the worldwide movement towards a higher quality of life has not yet been achieved for an important share of the world's population.

Les parlementaires suisses entre démocratisation et professionnalisation (1910-2010). Biographie collective des élus fédéraux et réformes du Parlement helvétique

Notre travail de thèse vise à analyser, d'une part, les principales réformes du Parlement fédéral adoptées au cours du 20e siècle et, d'autre part, l'évolution du profil sociographique pour six cohortes d'élus fédéraux (1910, 1937, 1957, 1980, 2000 et 2010), sous l'angle de sa démocratisation et de sa professionnalisation. La thèse comprend trois axes de recherche principaux. Premièrement, nous nous penchons sur les deux réformes institutionnelles censées favoriser la démocratisation du recrutement parlementaire, à savoir l'adoption de la proportionnelle pour l'élection du Conseil national en 1918 et l'introduction du suffrage féminin à l'échelon fédéral en 1971. Nous abordons également les réformes du Parlement visant, depuis les années 1970, à sa revalorisation et à sa professionnalisation. Le deuxième axe porte sur la réalisation d'un portrait collectif des élus fédéraux pour la période 1910-1980, dans le but de vérifier l'impact des réformes des règles électorales (proportionnelle et suffrage féminin) sur le profil des députés et sénateurs. Enfin, dans le troisième axe, nous abordons les transformations du profil socio-professionnel des parlementaires pendant la période plus récente (1980-2010), en lien avec la professionnalisation accrue de l'Assemblée fédérale et les changements des rapports de force partisans. Nos résultats permettent de mettre en évidence plusieurs éléments de continuité (prédominance de la catégories des indépendants, notamment des avocats, des chefs d'entreprise et des agriculteurs, et sous-représentation des salariés du secteur public ; fort ancrage local), ainsi que certains facteurs de rupture (présence accrue des femmes, moindre importance de la carrière militaire). D'autres changements dans le profil sont liés au processus récent de professionnalisation, contesté et inachevé, qui a favorisé néanmoins l'émergence de nouveaux profils sociologiques d'élus, en termes de formation, de profession (apparition du groupe des parlementaires professionnels) et de cumul des mandats économiques et politiques, avec cependant de fortes variations entre les partis et entre les deux Chambres. - Our PhD thesis aims at analysing, on the one hand, the main reforms of the Federal Parliament adopted during the 20th century and, on the other hand, the evolution of sociographical profile for six cohorts of Swiss MPs (1910, 1937, 1957, 1980, 2000 and 2010) in terms of their democratization and professionalization. Our research is composed of three main parts. Firstly, we analyse two institutional reforms which intended to promote the democratization of parliamentary recruitment, namely the adoption of proportional representation (PR) in 1918 for the election of the National Council and the introduction of women's suffrage at the federal level in 1971. We also deal with parliamentary reforms that, since the 1970s, have aimed at reasserting the political status of the Federal Assembly and at professionalizing its members. Secondly, we carry out a collective biography of Swiss MPs during the period 1910-1980, in order to verify the impact of electoral reforms (PR and women's suffrage) on the profiles of deputies and senators. Finally, we discuss the transformation of the MPs' socio-_professional profiles during the recent period (1980-2010) in connection with the increased professionalization of the Federal Assembly and the changes of the power relations within the Parliament. Our results allow us to highlight several elements of continuity (the predominance of self-employed persons, especially lawyers, business managers and farmers, and the underrepresentation of public employees; stronger background in local politics), as well as some factors of discontinuity (increased presence of women and lesser importance of the military career). Other changes of the parliamentarians' profile are related to the recent process of professionalization. Although contested and unfinished, it has promoted new sociological profiles in terms of educational background, profession (growth of the professional parliamentarians) and number of political and economic mandates held simultaneously, however with important variations between parties and between Lower and Upper House.

Reflections on Young Women and the Youth Crisis in Sub-Saharan Africa

There has been an upsurge in academic studies on youth in Sub-Saharan Africa since the last decade of the 20th century, underlining the growing importance that generational cleavages seem to play in today’s societies. However, gender has been neglected in research and policies bearing on youth, unveiling a rather negative and limited approach to Sub-Saharan African youth: limit situations are those most focused on (as the role of youth in conflicts), young males being perceived as the most active in those contexts and who therefore shall be the focus of political (and academic) attention. Acknowledging the need to integrate gender in the approaches to youth, this paper tries to grasp, through a preliminary literature review, how the predicaments of the so-called “youth crisis” are lived and perceived by young girls, and identify the main themes and theoretical perspectives of the literature that has tried to explore this thematic.

Analysis of susceptibility to human immunodeficiency virus 1 (HIV-1) by comparative genetics

Summary [résumé français voir ci-dessous] From the beginning of the 20th century the world population has been confronted with the human immune deficiency virus 1 (HIV-1). This virus has the particularity to mutate fast, and could thus evade and adapt to the human host. Our closest evolutionary related organisms, the non-human primates, are less susceptible to HIV-1. In a broader sense, primates are differentially susceptible to various retrovirus. Species specificity may be due to genetic differences among primates. In the present study we applied evolutionary and comparative genetic techniques to characterize the evolutionary pattern of host cellular determinants of HIV-1 pathogenesis. The study of the evolution of genes coding for proteins participating to the restriction or pathogenesis of HIV-1 may help understanding the genetic basis of modern human susceptibility to infection. To perform comparative genetics analysis, we constituted a collection of primate DNA and RNA to allow generation of de novo sequence of gene orthologs. More recently, release to the public domain of two new primate complete genomes (bornean orang-utan and common marmoset) in addition of the three previously available genomes (human, chimpanzee and Rhesus monkey) help scaling up the evolutionary and comparative genome analysis. Sequence analysis used phylogenetic and statistical methods for detecting molecular adaptation. We identified different selective pressures acting on host proteins involved in HIV-1 pathogenesis. Proteins with HIV-1 restriction properties in non-human primates were under strong positive selection, in particular in regions of interaction with viral proteins. These regions carried key residues for the antiviral activity. Proteins of the innate immunity presented an evolutionary pattern of conservation (purifying selection) but with signals of relaxed constrain if we compared them to the average profile of purifying selection of the primate genomes. Large scale analysis resulted in patterns of evolutionary pressures according to molecular function, biological process and cellular distribution. The data generated by various analyses served to guide the ancestral reconstruction of TRIM5a a potent antiviral host factor. The resurrected TRIM5a from the common ancestor of Old world monkeys was effective against HIV-1 and the recent resurrected hominoid variants were more effective against other retrovirus. Thus, as the result of trade-offs in the ability to restrict different retrovirus, human might have been exposed to HIV-1 at a time when TRIM5a lacked the appropriate specific restriction activity. The application of evolutionary and comparative genetic tools should be considered for the systematical assessment of host proteins relevant in viral pathogenesis, and to guide biological and functional studies. Résumé La population mondiale est confrontée depuis le début du vingtième siècle au virus de l'immunodéficience humaine 1 (VIH-1). Ce virus a un taux de mutation particulièrement élevé, il peut donc s'évader et s'adapter très efficacement à son hôte. Les organismes évolutivement le plus proches de l'homme les primates nonhumains sont moins susceptibles au VIH-1. De façon générale, les primates répondent différemment aux rétrovirus. Cette spécificité entre espèces doit résider dans les différences génétiques entre primates. Dans cette étude nous avons appliqué des techniques d'évolution et de génétique comparative pour caractériser le modèle évolutif des déterminants cellulaires impliqués dans la pathogenèse du VIH- 1. L'étude de l'évolution des gènes, codant pour des protéines impliquées dans la restriction ou la pathogenèse du VIH-1, aidera à la compréhension des bases génétiques ayant récemment rendu l'homme susceptible. Pour les analyses de génétique comparative, nous avons constitué une collection d'ADN et d'ARN de primates dans le but d'obtenir des nouvelles séquences de gènes orthologues. Récemment deux nouveaux génomes complets ont été publiés (l'orang-outan du Bornéo et Marmoset commun) en plus des trois génomes déjà disponibles (humain, chimpanzé, macaque rhésus). Ceci a permis d'améliorer considérablement l'étendue de l'analyse. Pour détecter l'adaptation moléculaire nous avons analysé les séquences à l'aide de méthodes phylogénétiques et statistiques. Nous avons identifié différentes pressions de sélection agissant sur les protéines impliquées dans la pathogenèse du VIH-1. Des protéines avec des propriétés de restriction du VIH-1 dans les primates non-humains présentent un taux particulièrement haut de remplacement d'acides aminés (sélection positive). En particulier dans les régions d'interaction avec les protéines virales. Ces régions incluent des acides aminés clé pour l'activité de restriction. Les protéines appartenant à l'immunité inné présentent un modèle d'évolution de conservation (sélection purifiante) mais avec des traces de "relaxation" comparé au profil général de sélection purifiante du génome des primates. Une analyse à grande échelle a permis de classifier les modèles de pression évolutive selon leur fonction moléculaire, processus biologique et distribution cellulaire. Les données générées par les différentes analyses ont permis la reconstruction ancestrale de TRIM5a, un puissant facteur antiretroviral. Le TRIM5a ressuscité, correspondant à l'ancêtre commun entre les grands singes et les groupe des catarrhiniens, est efficace contre le VIH-1 moderne. Les TRIM5a ressuscités plus récents, correspondant aux ancêtres des grands singes, sont plus efficaces contre d'autres rétrovirus. Ainsi, trouver un compromis dans la capacité de restreindre différents rétrovirus, l'homme aurait été exposé au VIH-1 à une période où TRIM5a manquait d'activité de restriction spécifique contre celui-ci. L'application de techniques d'évolution et de génétique comparative devraient être considérées pour l'évaluation systématique de protéines impliquées dans la pathogenèse virale, ainsi que pour guider des études biologiques et fonctionnelles

The Harsh Fight against Poverty in Sao Tome and Principe

post-independence, and on the other hand, the testimonies from Sao Tomeans individuals from different social conditions and different degrees of political responsibility, this article approaches some possible connections between poverty and micro-violence in Sao Tome and Principe. It is offered an outline of research for the difficulties of the eradication of poverty and, concomitantly, the diffusion of a growing feeling of social disruption, processes in all contrary to the promises of independence for this archipelago. Frequently, the archipelago’s visitors make hasty opinions about the imaginary effortlessness of governing two islands with less than one hundred and fifty thousand citizens. However, contrary to this very common prejudice, the micro-insularity is considered an obstacle to development, a notion shared by many Sao Tomeans. Could micro-insularity equally be, under this outlook, an impoverishment-inducing factor? Regarding the development, there is some truth in this diagnosis, which the Sao Tomeans also use to justify their current difficulties. Throughout the 70s and 80s, the MLSTP – Movimento de Libertação de São Tomé e Príncipe (Movement for the Liberation of Sao Tome and Principe) endorsed a development founded on an expansion of cacao cultures, at the expenses of an intensified production rate, and on an incipient industrialization, which was intended to avoid importations and economic dependency. At the time, the Sao Tomeans leaders justified the rising daily difficulties, quite the opposite of the promises made during the independence, with an economic disarticulation resulting from the gradual abandonment of economic infrastructures inflicted by the last batch of colonists, which affected the cacao plantations too. Simultaneously, both the inefficiency and cost of the industrial endeavors launched after the independence and the erosion of labor and social relationships in nationalized farms had been rather neglected.

Cantant entre guerres : música coral per a veus blanques a França i Catalunya a principis del segle XX

Aquest treball busca definir algunes característiques comunes d'obres musicals escrites a principis del segle XX per compositors francesos i catalans per a cor de veus blanques, mitjançant l'estudi de les seves biografies i l'anàlisi de les pròpies obres. Aquestes peces, compostes en llocs i moments diferents, convergeixen però en alguns punts estilístics, transcendint les fronteres per contribuir a l'elaboració d'un llenguatge propi d'un entorn cultural més ampli, de París a Barcelona.

The impact of investment in education on economic development: Spain in comparative perspective (1860-2000)

Throughout the 19th century and until the mid-20th century, in terms of long-terminvestment in human capital and, above all, in education, Spain lagged far behind theinternational standards and, more specifically, the levels attained by its neighbours inEurope. In 1900, only 55% of the population could read; in 1950, the figure was 93%.This no doubt contributed to a pattern of slower economic growth in which thephysical strength required for agricultural work, measured here through height, had alarger impact than education on economic growth. It was not until the 1970s, with thearrival of democracy, that the Spanish education system was modernized and theinfluence of education on economic growth increased.

Why England? Demand, growth and inequality during the Industrial Revolution

Why was England first? And why Europe? We present a probabilistic model that builds on big-push models by Murphy, Shleifer and Vishny (1989), combined with hierarchical preferences. The interaction of exogenous demographic factors (in particular the English low-pressure variant of the European marriage pattern)and redistributive institutions such as the old Poor Law combined to make an Industrial Revolution more likely. Essentially, industrialization is the result of having a critical mass of consumers that is rich enough to afford (potentially) mass-produced goods. Our model is then calibrated to match the main characteristics of the English economy in 1750 and the observed transition until 1850.This allows us to address explicitly one of the key features of the British IndustrialRevolution unearthed by economic historians over the last three decades the slowness of productivity and output change. In our calibration, we find that the probability of Britain industrializing is 5 times larger than France s. Contrary to the recent argument by Pomeranz, China in the 18th century had essentially no chance to industrialize at all. This difference is decomposed into a demographic and a policy component, with the former being far more important than the latter.

The rise and decline of children's labour participation levels during the early stages of industrialisation. Catalonia (1850-1925)

This article aims to analyse the reasons for the intensive use of childlabour in the 19th century and its subsequent decline in the first thirdof the 20th century in the context of an economy with a highly flexiblelabour supply like that of Catalonia. During the second half of the 19thcentury,factors relating to family economies, such as numerous familiesand low wages for adults, along with the technologies of the time thatrequired manual labour resources, would appear to explain the intensiveuse of child labour to the detriment of schooling. The technologicalchanges that occurred during the first third of the 20th century, thedemographic transition and adult wage increase (for both men and women)explain the schooling of children up to the age of 15 and theconsequent practical abolition of child labour in that new era ofeconomic modernisation.

Oil and economy in Mexico, 1900-1930s

This brief essay reviews the macro framework of oil and economy in Mexicoin the early days of the oil industry, from 1900 to 1938. The first sectiondisplays the figures of production at the world level and shows how Mexicobecome a major oil producer in the 1920s. The second section look at theMexican economy of the first third of the century followed by a thirdsection on the importance of the oil sector in terms of trade and fiscalincome. The last section reviews the literature and the outlooks of thecontemporaries over the development of the oil industry in the early partof the 20th century. The paper will be of use for those producing in depthanalyses of the Mexican oil industry in this period.

A influência do e-learning no capital humano

Na Europa e nas últimas décadas do Século XX, a emergência da Sociedade de Informação veio impor às organizações a necessidade de que, para além das inovações tecnológicas, haja uma preocupação relativamente aos bens intangíveis como a informação, as novas metodologias de trabalho e o know how (Batista, 2002). Paralelamente a estas inovações, as Instituições de Ensino Superior têm contribuído para a evolução do Capital Humano, como ativo intangível intrínseco ao Homem. Em Portugal e no contexto do Ensino/Formação a Distância parecem continuar a existir, ainda, em algumas instituições, problemas de identificação, e de descriminação das vantagens no que concerne à estrutura aberta e flexível, com o estudante/formando a ter algumas dificuldades em adaptar o seu perfil e interesses profissionais ao tipo de aprendizagem que mais se lhe adequa. O e-learning surge como um método de Ensino/Formação a Distância, só possível com a especificidade dos processos pedagógicos e em complementaridade com as Tecnologias de Informação e Comunicação (TIC), uma vez que são estas que lhe dão o suporte necessário à sua concretização. O e-learning ao proporcionar novas formas de comunicação, de interação e de confronto de ideias, permite uma aprendizagem baseada na partilha de saberes, tendo em consideração as experiências e os objetivos profissionais dos formandos. Dentro destes pressupostos, achámos importante fazer uma investigação a partir de Instituições de Ensino Superior Portuguesas, de modo a percebermos qual o papel e a influência que o e-learning desempenha nos objetivos das organizações académicas em geral e no Capital Humano dos seus Estudantes/Formandos em particular. A partir da questão da investigação foram definidos os objetivos e hipóteses de investigação de modo a que ao ser enunciada uma metodologia esta englobe fatores que foquem os elementos necessários à confirmação, ou não, dos pressupostos enunciados. Foi analisada documentação diversa, criado um questionário e conduzidas entrevistas, de modo a obter e potenciar a informação necessária e suficiente para o efeito. A recolha de dados para posterior análise e os resultados depois de interpretados, permitirão responder aos propósitos expressos desde o início da investigação.

Did colonization matter for growth? An empirical exploration into the historical causes of Africa's underdevelopment

We investigate the impact of 20th--century European colonizationon growth in Africa. We find that in the 1960--88 period growth has beenfaster for dependencies than for colonies; for British and Frenchcolonies than for Portuguese, Belgian and Italian ones; and for countrieswith less economic penetration during the colonial period. On average,African growth accelerates after decolonization. Proxies for colonialheritage add explanatory power to growth regressions and make indicatorsfor human capital, political and ethnic instability lose significance.Colonial variables capture the same effects of a sub--Saharan dummy andreduce its significance when jointly included in a cross sectionalregression with 98 countries.
