Changements démographiques et inégalités éducatives à Ouagadougou

Depuis plusieurs décennies, des études empiriques réalisées sur plusieurs pays développés ou en émergence ont montré que la baisse de la taille de la famille favorise l’investissement dans l’éducation des enfants, expliquant qu’un nombre élevé d’enfants a un effet d’amenuisement des ressources familiales. Les retombées positives de la baisse de la fécondité sur l’éducation sont largement étudiées et connues. En dépit des résultats controversés des premières études portant sur les pays de l’Afrique de l’Ouest, les récentes études empiriques tendent à confirmer l’effet positif de la baisse de la taille de la famille dans le contexte africain, du moins en milieu urbain. Par contre, jusqu’à présent, très peu d’études semblent intéressées à analyser la répartition de ces retombées entre les enfants, et encore moins à comprendre comment ces dernières affecteraient la structure des inégalités éducatives existantes. Notre étude s’intéresse à explorer la potentielle dimension démographique des inégalités socioéconomiques, notamment les inégalités éducatives dans le contexte de la baisse de la fécondité. Elle vise à apporter des évidences empiriques sur le lien entre la réduction de la taille de la famille et les inégalités éducatives au sein des ménages dans le contexte d’Ouagadougou, Capitale du Burkina Faso, qui connait depuis quelques décennies la chute de la fécondité. Elle analyse aussi l’effet de cette réduction sur la transmission intergénérationnelle des désavantages éducatifs. Pour ce faire, nous proposons un cadre conceptuel pour comprendre les mécanismes par lesquels la relation entre la réduction de la taille de la famille et les inégalités éducatives se tisse. Ce cadre conceptuel s’appuie sur une recension des écrits de divers auteurs à ce sujet. Par la suite, nous procédons à des analyses empiriques permettant de tester ces liens en utilisant les données du projet Demtrend collectées. Les résultats empiriques sont présentés sous forme d’articles scientifiques. Les conclusions du premier article indiquent que la relation entre le nombre d’enfants de la famille et l’éducation varie selon le contexte socioéconomique. En effet, pour les générations qui ont grandi dans un contexte socioéconomique colonial et postcolonial, où le mode de production était essentiellement agricole et l’éducation formelle n’était pas encore valorisée sur le marché du travail, la relation est très faible et positive. Par contre, pour les récentes générations, nous avons observé que la relation devient négative et fortement significative. De plus, les résultats de cet article suggèrent aussi que la famille d’origine des femmes a une incidence significative sur leur comportement de fécondité. Les femmes dont la mère avait un niveau de scolarité élevé (et étaient de statut socioéconomique aisé) ont moins d’enfants comparativement à celles dont leurs parents avaient un faible niveau de scolarité (et pauvres). En retour, leurs enfants sont aussi les plus éduqués. Ce qui sous-tend à un éventuel effet de levier de la réduction de la taille de la famille dans le processus de transmission intergénérationnelle des désavantages éducatifs. Le second article fait une comparaison entre les ménages de grande taille et ceux de petite taille en matière d’inégalités éducatives entre les enfants au sein des ménages familiaux, en considérant le sexe, l’ordre de naissance et les termes d’interaction entre ces deux variables. Les résultats de cet article montrent que généralement les enfants des familles de petite taille sont plus scolarisés et atteignent un niveau d’éducation plus élevé que ceux des grandes familles. Toutefois, les filles ainées des petites familles s’avèrent moins éduquées que leurs pairs. Ce déficit persiste après avoir considéré seulement les ménages familiaux monogames ou encore après le contrôle de la composition de la fratrie. L’émancipation des femmes sur le marché du travail résultant de la réduction de la taille de la famille et la faible contribution des pères dans les activités domestiques expliqueraient en partie cette situation. Malheureusement, nous n’avons pas pu contrôler l’activité économique des mères dans les analyses. Finalement, dans le cadre du troisième et dernier article, nous avons examiné l’effet d’avoir été confié par le passé sur les inégalités éducatives au sein de la fratrie, en comparant ceux qui ont été confiés aux autres membres de leur fratrie qui n’ont jamais été confiés. Dans cet article, nous avons considéré l’aspect hétérogène du confiage en le différenciant selon le sexe, la relation de la mère avec le chef du ménage d’accueil et l’âge auquel l’enfant a été confié. Les résultats montrent qu’avoir été confié dans le passé influence négativement le parcours scolaire des enfants. Cependant, cet effet négatif reste fort et significatif que pour les filles qui ont été confiées après leurs 10 ans d’âge. Un profil qui correspond à la demande de main-d’œuvre en milieu urbain pour l’accomplissement des tâches domestiques, surtout dans le contexte de la baisse de la taille de la famille et l’émancipation des femmes sur le marché du travail.

La correspondance transatlantique des Prize Papers (1744-1763) : famille, commerce et communications en temps de guerre

Au cours des années comprises entre 1744 et 1763, le monde atlantique connaît deux guerres majeures. La France et ses colonies américaines sont impliquées dans une lutte acharnée contre l’Empire britannique. Les deux puissances rivales misent alors largement sur la guerre de course. Au-delà des conséquences commerciales et militaires évidentes, la guerre de course perturba aussi les communications transatlantiques. En effet, la prise d’un navire signifiait le plus souvent la perte des lettres qu’il transportait ou, dans le meilleur des cas, leur saisie, interrompant du même coup l’acheminement maritime du courrier. Les archives des Prize Papers, conservant des lettres et autres documents saisis par des corsaires britanniques, incarnent bien cette réalité. On y trouve notamment de nombreuses lettres françaises interceptées dans ces circonstances. Considérant que l’intérêt historique de ce fonds d’archives mérite d’être davantage souligné, cette recherche analysera donc certaines de ces correspondances françaises trouvées au sein des Prize Papers. À travers celles-ci, nous tenterons de reconstituer le système de communication transatlantique français et de ses acteurs en temps de guerre. Nous nous pencherons d’abord sur l’histoire de la constitution de ce fonds d’archives bien particulier, avant de présenter les pratiques de communication employées par les correspondants transatlantiques et les façons dont la guerre a pu les affecter. Il sera ensuite question des informations elles-mêmes qui furent véhiculées dans ce contexte si difficile.

Drilling for Papers in INKE

In this article, we discuss the first year research plan for the INKE interface design team, which focuses on a prototype for chaining. Interpretable as a subclass of Unsworths scholarly primitive of discovering, chaining is the process of beginning with an exemplary article, then finding the articles that it cites, the articles they cite, and so on until the reader begins to get a feel for the terrain. The chaining strategy is of particular utility for scholars working in new areas, either through doing background work for interdisciplinary interests or else by pursuing a subtopic in a domain that generates a paper storm of publications every year. In our prototype project, we plan to produce a system that accepts a seed article, tunnels through a number of levels of citation, and generates a summary report listing the most frequent authors and articles. One of the innovative features of this prototype is its use of the experimental oil and water interface effect, which uses text animation to provide the user with a sense of the underlying process.

Profils individuels et dynamiques interactionnelles des parents et des enfants à risque d’aliénation parentale dans un contexte d’une rupture conjugale litigieuse

L’aliénation parentale (AP) est un phénomène connu des intervenants sociolégaux œuvrant auprès des familles éclatées chez lesquelles on retrouve un haut niveau de conflits parentaux. Ce phénomène est peu étudié empiriquement et sa définition et les balises l’entourant demeurent à ce jour non circonscrites et suscitent confusion et controverse. Cette recherche n’a pas comme objectif de trancher sur ce qui est ou n’est pas de l’aliénation parentale, mais porte plutôt sur l’étude du phénomène de Détérioration du lien parent-enfant (DLPE), qui inclut une rupture complète du lien comme dans les cas d’AP, lors de séparations conjugales litigieuses. Cette thèse doctorale a pour objectif principal d’élargir notre compréhension sur les différents facteurs qui interagissent et qui mettent en place une situation familiale de DLPE. Le présent ouvrage est composé de quatre articles, dont trois sont empiriques. Le premier article est une synthèse critique des écrits théoriques et empiriques permettant de dégager les différents facteurs, conduites ou contextes individuels et relationnels associés à une DLPE. Il ressort que la plupart des écrits proviennent de comptes rendus cliniques. De plus, peu d’auteurs abordent ce phénomène dans une perspective systémique incluant une vision multifactorielle de cette situation. Plusieurs aspects demandent à être étudiés davantage : les caractéristiques individuelles, les comportements inappropriés des acteurs et les dynamiques familiales. En définitive, il importe d’établir les facteurs de résilience. Les articles 2, 3 et 4 ont été réalisés suite à une analyse qualitative de 17 dossiers d’expertise psychosociale de familles séparées en litige autour des accès des enfants. Le second article a pour objectif d’apporter un éclairage fouillé sur les structures de personnalité des parents impliqués dans de tels litiges. Il se dégage de cette analyse que les parents contribuent différemment à la dynamique familiale en fonction de leur profil de personnalité. Quatre profils parentaux ont émergé et permettent de discerner en quoi les parents aux conduites aliénantes se distinguent des parents dénigrés au niveau des profils de personnalité et en quoi la personnalité de ces parents est respectivement différente selon qu’ils maintiennent ou pas la relation avec leur enfant. L’analyse approfondie des profils parentaux a permis de formuler certains facteurs de risque et de protection relatifs à la structure de la personnalité des parents à risque d’une DLPE. Le troisième article a pour objectif d’évaluer par une lecture psychodynamique les différentes caractéristiques individuelles des enfants dans l’optique d’établir des pistes pouvant élucider pourquoi un enfant est résistant à une DLPE ou, au contraire, ne l’est pas. L’analyse qualitative fouillée des dossiers d’expertise a permis d’extraire différents facteurs de risque et de protection d’une DLPE chez ces enfants. Le quatrième article cherche à modéliser les différents facteurs de risque ou, au contraire, qui atténuent le risque de DLPE. Trois trajectoires dénotant une dynamique de DLPE ont émergé. Une modélisation systémique reprend l’ensemble des facteurs (dynamiques personnelles et relationnelles, contexte familial, système sociojuridique, personnes tierces et temps) émergeant de l’analyse et leur déploiement spécifique à chaque trajectoire.

MQFD: A Model for Synergizing TPM and QFD

This thesis presents the methodology of linking Total Productive Maintenance (TPM) and Quality Function Deployment (QFD). The Synergic power ofTPM and QFD led to the formation of a new maintenance model named Maintenance Quality Function Deployment (MQFD). This model was found so powerful that, it could overcome the drawbacks of TPM, by taking care of customer voices. Those voices of customers are used to develop the house of quality. The outputs of house of quality, which are in the form of technical languages, are submitted to the top management for making strategic decisions. The technical languages, which are concerned with enhancing maintenance quality, are strategically directed by the top management towards their adoption of eight TPM pillars. The TPM characteristics developed through the development of eight pillars are fed into the production system, where their implementation is focused towards increasing the values of the maintenance quality parameters, namely overall equipment efficiency (GEE), mean time between failures (MTBF), mean time to repair (MTIR), performance quality, availability and mean down time (MDT). The outputs from production system are required to be reflected in the form of business values namely improved maintenance quality, increased profit, upgraded core competence, and enhanced goodwill. A unique feature of the MQFD model is that it is not necessary to change or dismantle the existing process ofdeveloping house ofquality and TPM projects, which may already be under practice in the company concerned. Thus, the MQFD model enables the tactical marriage between QFD and TPM.First, the literature was reviewed. The results of this review indicated that no activities had so far been reported on integrating QFD in TPM and vice versa. During the second phase, a survey was conducted in six companies in which TPM had been implemented. The objective of this survey was to locate any traces of QFD implementation in TPM programme being implemented in these companies. This survey results indicated that no effort on integrating QFD in TPM had been made in these companies. After completing these two phases of activities, the MQFD model was designed. The details of this work are presented in this research work. Followed by this, the explorative studies on implementing this MQFD model in real time environments were conducted. In addition to that, an empirical study was carried out to examine the receptivity of MQFD model among the practitioners and multifarious organizational cultures. Finally, a sensitivity analysis was conducted to find the hierarchy of various factors influencing MQFD in a company. Throughout the research work, the theory and practice of MQFD were juxtaposed by presenting and publishing papers among scholarly communities and conducting case studies in real time scenario.

Weather and climate of Penisular India modulated by Extrinsic factors- Empirical and Numerical Perspectives

The Doctoral thesis focuses on the factors that influence the weather and climate over Peninsular Indias. The first chapter provides a general introduction about the climatic features over peninsular India, various factors dealt in subsequent chapters, such as solar forcing on climate, SST variability in the northern Indian Ocean and its influence on Indian monsoon, moisture content of the atmosphere and its importance in the climate system, empirical formulation of regression forecast of climate and some aspects of regional climate modeling. Chapter 2 deals with the variability in the vertically integrated moisture (VIM) over Peninsular India on various time scales. The third Chapter discusses the influence of solar activity in the low frequency variability in the rainfall of Peninsular India. The study also investigates the influence of solar activity on the horizontal and vertical components of wind and the difference in the forcing before and after the so-called regime shift in the climate system before and after mid-1970s.In Chapter 4 on Peninsular Indian Rainfall and its association with meteorological and oceanic parameters over adjoining oceanic region, a linear regression model was developed and tested for the seasonal rainfall prediction of Peninsular India.

Real Estate Development In India And The Behavior of Investors to Invest In The Real Estate Market: An Empirical Investigation

This study examines the behavioral factors that influence the Indian Investors to invest in the Real Estate Market. Among the various factors that affect the tendency of investors to invest in the real market, certain factors are greatly influenced the investors at greatest extend while others at least level. From this study it is revealed that motivation from the real estate developers and brokers (mean value- 3.46) is most influencing factor and happening of uncertain events (mean value- 1.75) is the least factor that influences the investors’ investment behavior. In this study, the behavioral factor like over confidence and the hypotheses regarding education, religion were analyzed and found that religious factor influences the Indian investors to invest in the real estate

Significance Of Product Type And Brand In The Purchasing Behaviour Of Cattle Feeds: An Empirical Study In Kerala

Cattle feed industry is a major segment of animal feed industry. This industry is gradually evolving into an organized sector and the feed manufactures are increasingly using modern and sophisticated methods that seek to incorporate best global practices. This industry has got high potential for growth in India, given the fact that the country is the world’s leading producer of milk and its production is expected to grow at a compounded annual growth rate of 4 per cent. Besides, the concept of branded cattle feed as a packaged commodity is fast gaining popularity in rural India. There can be a positive change in the demand for cattle feed because of factors like (i) shrinkage of open land for cattle grazing, urbanization and resultant shortage of conventionally used cattle feeds, and (ii) introduction of high yield cattle requires specialized feeds. Earlier research studies done by the present authors have revealed the significant growth prospects of the branded cattle feed industry, the feed consumption pattern and the relatively high share of branded feeds, feed consumption pattern based on product types (like, pellet and mash), composition of cattle feed market and the relatively large shares of Kerala Feeds Ltd. (KFL) and Kerala Solvent Extractions Ltd. (KSE) brands, the major factors influencing the purchasing decisions etc. As a continuation of the earlier studies, this study makes a closer look into the significance of product types in the buyer behavior, level of awareness about the brand and its implications on purchasing decisions, and the brandshifting behavior and its determinants

The empirical study of the price mechanism in the Chinese housing market

In China, the history of the establishment of the private housing market is pretty short. Actually in less then two decades, the market has grown from almost the scratch to playing an important role in the economy. A great achievement! But many problems also exist. They need to be properly addressed and solved. Price problem---simply put, housing price is too high--- is one of them, and this paper is focused on it. Three basic questions are posed, i.e. (1) how to judge the housing affordability? (2) why the housing price is so high? (3) how to solve the housing price problem. The paper pays particular attention to answering the second question. Except the numerous news reports and surveys show that most of the ordinary city dwellers complained about the high housing price, the mathematical means, the four ratios, are applied to judge the housing affordability in Shanghai and Shenzhen. The results are very clear that the price problem is severe. So why? Something is wrong with the price mechanism. This research shows that mainly these five factors contribute to the price problem: the housing reform, the housing development model, the unbalanced housing market, the housing project financing and the poor governmental management. Finally the paper puts forward five suggestions to solve the housing price problem in first-hand private Chinese housing market. They include: the establishment of real estate information system, the creation of specific price management department, the government price regulation, the property tax and the legalization of "cushion money".

Social Inequality and Social Policy outside the OECD

Almost all Latin American countries are still marked by extreme forms of social inequality – and to an extent, this seems to be the case regardless of national differences in the economic development model or the strength of democracy and the welfare state. Recent research highlights the fact that the heterogeneous labour markets in the region are a key source of inequality. At the same time, there is a strengthening of ‘exclusive’ social policy, which is located at the fault lines of the labour market and is constantly (re-)producing market-mediated disparities. In the last three decades, this type of social policy has even enjoyed democratic legitimacy. These dynamics challenge many of the assumptions guiding social policy and democratic theory, which often attempt to account for the specificities of the region by highlighting the purported flaws of certain policies. We suggest taking a different perspective: social policy in Latin American should not be grasped as a deficient or flawed type of social policy, but as a very successful relation of political domination. ‘Relational social analysis’ locates social policy in the ‘tension zone’ constituted by the requirements of economic reproduction, demands for democratic legitimacy and the relative autonomy of the state. From this vantage point, we will make the relation of domination in question accessible for empirical research. It seems particularly useful for this purpose to examine the recent shifts in the Latin American labour markets, which have undergone numerous reforms. We will examine which mechanisms, institutions and constellations of actors block or activate the potentials of redistribution inherent in such processes of political reform. This will enable us to explore the socio-political field of forces that has been perpetuating the social inequalities in Latin America for generations.

Core Labor Rights

The working paper’s main objective is to explore the extent to which non-compliance to international labor rights is caused by global competition. From the perspective of institutional economics, compliance with core labor rights is beneficial for sustainable development. Nonetheless, violations of these rights occur on a massive scale. The violators usually blame competitive pressures. A number of studies have come to the conclusion that non-compliance does not provide for a competitive edge, thereby denying any economic rationale for non-compliance. While we sympathize with this conclusion, we find that these studies suffer from faulty assumptions in the design of their regression analyses. The assumption of perfect markets devoid of power relations is particularly unrealistic. While workers' rights promise long-term benefits, they may incur short-term production cost increases. On the supply side, the production sites with the highest amount of labor rights violations are characterized by a near perfect competitive situation. The demand side, however, is dominated by an oligopoly of brand name companies and large retailers. Facing a large pool of suppliers, these companies enjoy more bargaining power. Developing countries, the hosts to most of these suppliers, are therefore limited in their ability to raise labor standards on their own. This competitive situation, however, is the very reason why labor rights have to be negotiated internationally. Our exploration starts with an outline of the institutionalist argument of the benefits of core labor rights. Second, we briefly examine some cross-country empirical studies on the impact of trade liberalization (as a proxy for competitive pressures). Third, we develop our own argument which differentiates the impact of trade liberalization along the axes of labor- and capital-intensive production as well as low and medium skill production. Finally, we present evidence from a study on the impact of trade liberalization in Indonesia on the garment industry as an example of a low skill, laborintensive industry on the one hand, and the automobile as an example for a medium skill, capital-intensive industry on the other hand. Because the garment industry’s workforce consists mainly of women, we also discuss the gender dimension of trade liberalization.

From evolution to co-evolution – An empirical study of the role of innovation, policy and public research in industrial dynamics

In the past decades since Schumpeter’s influential writings economists have pursued research to examine the role of innovation in certain industries on firm as well as on industry level. Researchers describe innovations as the main trigger of industry dynamics, while policy makers argue that research and education are directly linked to economic growth and welfare. Thus, research and education are an important objective of public policy. Firms and public research are regarded as the main actors which are relevant for the creation of new knowledge. This knowledge is finally brought to the market through innovations. What is more, policy makers support innovations. Both actors, i.e. policy makers and researchers, agree that innovation plays a central role but researchers still neglect the role that public policy plays in the field of industrial dynamics. Therefore, the main objective of this work is to learn more about the interdependencies of innovation, policy and public research in industrial dynamics. The overarching research question of this dissertation asks whether it is possible to analyze patterns of industry evolution – from evolution to co-evolution – based on empirical studies of the role of innovation, policy and public research in industrial dynamics. This work starts with a hypothesis-based investigation of traditional approaches of industrial dynamics. Namely, the testing of a basic assumption of the core models of industrial dynamics and the analysis of the evolutionary patterns – though with an industry which is driven by public policy as example. Subsequently it moves to a more explorative approach, investigating co-evolutionary processes. The underlying questions of the research include the following: Do large firms have an advantage because of their size which is attributable to cost spreading? Do firms that plan to grow have more innovations? What role does public policy play for the evolutionary patterns of an industry? Are the same evolutionary patterns observable as those described in the ILC theories? And is it possible to observe regional co-evolutionary processes of science, innovation and industry evolution? Based on two different empirical contexts – namely the laser and the photovoltaic industry – this dissertation tries to answer these questions and combines an evolutionary approach with a co-evolutionary approach. The first chapter starts with an introduction of the topic and the fields this dissertation is based on. The second chapter provides a new test of the Cohen and Klepper (1996) model of cost spreading, which explains the relationship between innovation, firm size and R&D, at the example of the photovoltaic industry in Germany. First, it is analyzed whether the cost spreading mechanism serves as an explanation for size advantages in this industry. This is related to the assumption that the incentives to invest in R&D increase with the ex-ante output. Furthermore, it is investigated whether firms that plan to grow will have more innovative activities. The results indicate that cost spreading serves as an explanation for size advantages in this industry and, furthermore, growth plans lead to higher amount of innovative activities. What is more, the role public policy plays for industry evolution is not finally analyzed in the field of industrial dynamics. In the case of Germany, the introduction of demand inducing policy instruments stimulated market and industry growth. While this policy immediately accelerated market volume, the effect on industry evolution is more ambiguous. Thus, chapter three analyzes this relationship by considering a model of industry evolution, where demand-inducing policies will be discussed as a possible trigger of development. The findings suggest that these instruments can take the same effect as a technical advance to foster the growth of an industry and its shakeout. The fourth chapter explores the regional co-evolution of firm population size, private-sector patenting and public research in the empirical context of German laser research and manufacturing over more than 40 years from the emergence of the industry to the mid-2000s. The qualitative as well as quantitative evidence is suggestive of a co-evolutionary process of mutual interdependence rather than a unidirectional effect of public research on private-sector activities. Chapter five concludes with a summary, the contribution of this work as well as the implications and an outlook of further possible research.

An Empirical Comparison of SNoW and SVMs for Face Detection

Impressive claims have been made for the performance of the SNoW algorithm on face detection tasks by Yang et. al. [7]. In particular, by looking at both their results and those of Heisele et. al. [3], one could infer that the SNoW system performed substantially better than an SVM-based system, even when the SVM used a polynomial kernel and the SNoW system used a particularly simplistic 'primitive' linear representation. We evaluated the two approaches in a controlled experiment, looking directly at performance on a simple, fixed-sized test set, isolating out 'infrastructure' issues related to detecting faces at various scales in large images. We found that SNoW performed about as well as linear SVMs, and substantially worse than polynomial SVMs.
