Migration and Wellbeing at the Lower Echelons of the Economy: A Study of Delhi Slums

This paper based on a primary survey of households (2004-05) in the slum clusters of Delhi examines whether migrants are likely to experience upward mobility in their place of destination or alternatively, if they merely transfer their poverty from rural areas to large cities. First, a simple bifurcation of population in terms of poor and non-poor sub-groups is examined along with the incidence of poverty across different categories of occupations and non-workers. Then, an explanation of the variations in per capita expenditure across households is provided, and a binomial logit model (poor/non-poor) is developed identifying the variables which raise (or reduce) the probability of being non-poor (or poor). Next, an estimate of the wellbeing (deprivation) index is derived from factor analysis of a large number of variables including demographic and economic aspects of households. Empirical findings suggest that while duration of migration and the wellbeing index do not have a definite relationship, migrant households who have been in the city for a very long time have a higher wellbeing index on average than those who migrated in the last ten years. This tends to support the view that migrants do not merely transfer rural poverty to urban areas, and further that population mobility yields improvement in the living standard, if only in the very long term. Implementation of "employment-cum-shelter" support schemes in the urban areas may contribute to their wellbeing.

Transport Development and the Evolution of Economic Geography

In this paper, based on the recent advances in the new economic geography (e.g., Fujita, Krugman and Venables [12]), we analyze impacts of transport costs on the spatial patterns of economic agglomeration. We first identify prototypes from the existing models, and explain the mechanism of how transport costs influence the balance between economic forces of agglomeration and dispersion. We then investigate the transformation of the agglomeration/dispersion patterns given gradually decreasing transport costs for different goods.

Proposal for a semantic hierarchy of terminological metaphors in science and technology

Cognitive linguistics is considered as one of the most appropriate approaches to the study of scientific and technical language formation and development, where metaphor is accepted to play an essential role. This paper, based on the Cognitive Theory of Metaphor, takes as the starting point the terminological metaphors established in the research project METACITEC(Note 1), which was developed with the purpose of unfolding constitutive metaphors and their function in the language of science and technology. After the analysis of metaphorical terms and using a mixed corpus from the fields of Agriculture, Geology, Mining, Metallurgy, and other related technical fields, this study presents a proposal for a hierarchy of the selected metaphors underlying the scientific conceptual system, based on the semantic distance found in the projection from the source domain to the target domain. We argue that this semantic distance can be considered as an important parameter to take into account in order to establish the metaphoricity of science and technology metaphorical terms. The findings contribute to expand on the CTM stance that metaphor is a matter of cognition by reviewing the abstract-concrete conceptual relationship between the target and source domains, and to determine the role of human creativity and imagination in the language of science and technology configuration

La transformación de la morada: una investigación sobre los invariantes arquitectónicos en la vivienda contemporánea

Le Corbusier denominó la nueva casa como la "machine à habiter / máquina de habitar", adaptándola a la revolución industrial que desde el inicio del siglo XX estaba cambiando el mundo. La casa, entendida como una máquina, sería un objeto útil, fabricado mediante el ensamblaje de piezas industrializadas al igual que un coche, un avión o un barco. Pero más adelante, en el prólogo del libro ‘Precisiones’, titulado ‘Prólogo americano’. Le Corbusier traslada sus ideas después del viaje a las Américas, escritas en el barco de regreso a Europa y en ellas encontramos la prueba más evidente de que algo está cambiando en él. En este nuevo enfoque contribuyen probablemente muchas cosas, tal vez algunas nunca lleguemos a saberlas, pero entre las que con toda probabilidad lo hacen de forma decisiva, están algunos de sus viajes. Norte de África, España o América del Sur. En los suburbios de Buenos Aires o en Río, llenos de casas hechas de plancha ondulada, sin corazón y sin alma, y que, a pesar de todo, tienen uno y otra; Le Corbusier recibe una lección de arquitectura que nunca olvidará y que le llevará a decir: “he visto una vivienda obrera de plancha ondulada, pero muy bien puesta, en la cual un rosal adornaba la puerta. Era todo un poema de los tiempos modernos” O bien “busco con verdadero afán esas casas que son casas de hombres y no casas de arquitectos". Al final de su vida, libre de un compromiso político o de una atadura excesivamente estricta con la construcción; sus propuestas son más orgánicas y no tan estructurales, basta ver la Cabanon que se construye para él y su mujer. En este trabajo; iniciado sobre la base de la conferencia que Martin Heidegger pronuncia el 5 de agosto de 1951 en Darmstadt, “Bauen Wohnen Denken”, apoyándose en el escrito de Santa Teresa de Cepeda (1515-1582), y guiados por sus siete Moradas del “Castillo Interior”, escrito del año 1577; se estudia la transformación de la casa y la invariancia de la morada. La casa posee uno de los mayores poderes de integración para los pensamientos, los recuerdos y los sueños del hombre. La casa en la vida del hombre, suplanta contingencias, multiplica sus consejos de continuidad. Sin ella el hombre sería un ser disperso. Es cuerpo y alma. Es el primer mundo del ser humano... Y siempre, en sus sueños, la casa es una gran cuna, como nos dice Bachelard. Ha habido una evidente evolución del concepto de vivienda, a lo largo del tiempo pero aún así todas las moradas siguen siendo reflejo de sus habitantes. La casa y la morada son dos cosas distintas. Cuando un hombre hace suya una casa, encuentra su morada. ABSTRACT Le Corbusier named the new house as the "machine à habiter / machine for living", adapting it to the industrial revolution that was changing the world from the beginning of the twentieth century. The house, resembled as a machine, was a useful object made by the assembly of industrial pieces like a car, an airplane or a boat. But later, after his trip to the Americas, and reflected at the preface, 'American Prologue', of his book called 'Clarifications', Le Corbusier evolved his ideas into a new way of thinking. Wrote on the boat back to Europe, the lines written in this book are the clear evidence that something has changed in him. We might never get to know all of the variables that influenced his new approach, but we can be certain that the trips to South America, North Africa and Spain played a pivotal role on the evolution of his thinking. In the suburbs of Buenos Aires or Rio, where he was exposed to roughly made houses, without any heart or soul, but nevertheless owned by men, Le Corbusier learnt an unforgettable lesson. Hence, he would retrospect: "I saw a corrugated iron worker house, but very well decorated with a rosebush garnishing the front door. It was a poem of the modern times" or "I deeply look forward for those houses that are people’s homes not architect’s ones". At the end of his life, free of political commitment or an overly strict attachment to the construction, his proposals are more organic and less structural, as represented by the Cabanon built for himself and his wife. In this paper, based on Martin’s Heidegger conference in Darmstadt “Bauen Wohnen Denken” (august 5th of 1951) and supported by Santa Teresa de Cepeda’s (1515-1582) letter and her Seven Mansions of the Interior Castle, transformation and invariance is studied. The house has one of the greatest powers of integration for the thoughts, memories and dreams of men. The house, in the life of an individual, overcome men contingencies and multiplies men advice for continuity. Without it, men would be a dispersed human being. The house is body and soul. It is the first world of the human being ... And always, in his dreams, “the house is a large cradle”, as said by Bachelard. There has been a clear evolution of the concept of housing over time. But after all, the house still remains as a reflection of its inhabitants. When a man makes a house his own, we can conclude, he has found what he can call his “morada”.

Innovative analytical strategies for the development of sensor devices and mass spectrometry methods

Il lavoro presentato in questa tesi di Dottorato è incentrato sullo sviluppo di strategie analitiche innovative basate sulla sensoristica e su tecniche di spettrometria di massa in ambito biologico e della sicurezza alimentare. Il primo capitolo tratta lo studio di aspetti metodologici ed applicativi di procedure sensoristiche per l’identificazione e la determinazione di biomarkers associati alla malattia celiaca. In tale ambito, sono stati sviluppati due immunosensori, uno a trasduzione piezoelettrica e uno a trasduzione amperometrica, per la rivelazione di anticorpi anti-transglutaminasi tissutale associati a questa malattia. L’innovazione di questi dispositivi riguarda l’immobilizzazione dell’enzima tTG nella conformazione aperta (Open-tTG), che è stato dimostrato essere quella principalmente coinvolta nella patogenesi. Sulla base dei risultati ottenuti, entrambi i sistemi sviluppati si sono dimostrati una valida alternativa ai test di screening attualmente in uso per la diagnosi della celiachia. Rimanendo sempre nel contesto della malattia celiaca, ulteriore ricerca oggetto di questa tesi di Dottorato, ha riguardato lo sviluppo di metodi affidabili per il controllo di prodotti “gluten-free”. Il secondo capitolo tratta lo sviluppo di un metodo di spettrometria di massa e di un immunosensore competitivo per la rivelazione di prolammine in alimenti “gluten-free”. E’ stato sviluppato un metodo LC-ESI-MS/MS basato su un’analisi target con modalità di acquisizione del segnale selected reaction monitoring per l’identificazione di glutine in diversi cereali potenzialmente tossici per i celiaci. Inoltre ci si è focalizzati su un immunosensore competitivo per la rivelazione di gliadina, come metodo di screening rapido di farine. Entrambi i sistemi sono stati ottimizzati impiegando miscele di farina di riso addizionata di gliadina, avenine, ordeine e secaline nel caso del sistema LC-MS/MS e con sola gliadina nel caso del sensore. Infine i sistemi analitici sono stati validati analizzando sia materie prime (farine) che alimenti (biscotti, pasta, pane, etc.). L’approccio sviluppato in spettrometria di massa apre la strada alla possibilità di sviluppare un test di screening multiplo per la valutazione della sicurezza di prodotti dichiarati “gluten-free”, mentre ulteriori studi dovranno essere svolti per ricercare condizioni di estrazione compatibili con l’immunosaggio competitivo, per ora applicabile solo all’analisi di farine estratte con etanolo. Terzo capitolo di questa tesi riguarda lo sviluppo di nuovi metodi per la rivelazione di HPV, Chlamydia e Gonorrhoeae in fluidi biologici. Si è scelto un substrato costituito da strips di carta in quanto possono costituire una valida piattaforma di rivelazione, offrendo vantaggi grazie al basso costo, alla possibilità di generare dispositivi portatili e di poter visualizzare il risultato visivamente senza la necessità di strumentazioni. La metodologia sviluppata è molto semplice, non prevede l’uso di strumentazione complessa e si basa sull’uso della isothermal rolling-circle amplification per l’amplificazione del target. Inoltre, di fondamentale importanza, è l’utilizzo di nanoparticelle colorate che, essendo state funzionalizzate con una sequenza di DNA complementare al target amplificato derivante dalla RCA, ne permettono la rivelazione a occhio nudo mediante l’uso di filtri di carta. Queste strips sono state testate su campioni reali permettendo una discriminazione tra campioni positivi e negativi in tempi rapidi (10-15 minuti), aprendo una nuova via verso nuovi test altamente competitivi con quelli attualmente sul mercato.

How I Learned to Stop Worrying and Love the Bits: Archival Motivation in the Digital Age

Why do people become archivists? Historically (and anecdotally) it was a deep love of musty, old records that drew people to the profession. While there have been many other motivating forces that inspired would-be archivists, it is most often that one hears of people seeking jobs in archives for love of “the stuff,” as evidenced in Kate Thiemer’s blog post, Honest tips for wannabe archivists (2012). As a result of the continually advancing presence of digitized and born digital archival collections, the physical nature of archival “stuff” is changing. While there remains the physical imprint of digital information on floppy disks, CDs, DVDs, hard drives, and old computers; the aspects of these physical artifacts might not evoke the same visceral pull to the profession as musty, raspy, paper-based documents. In light of this shift in physical presentation of information, we are faced with the question: how does love of archival “stuff” translate to work in digital archives? What is and/or will be the pull to become a digital archivist? To answer these questions, we will perform a survey-based study where we will invite archivists who work with both traditional and digital archival material to answer questions related to the aspects of their work that inspired or motivated them to join the profession. What motivates people to become archivists? What aspects of digital archives do or can potentially motivate people to seek out a career as an archivist? What, if any, motivational factors for becoming a traditional archivist are the same as those for becoming a digital archivist? What, if any, motivational factors for becoming a traditional archivist are different from those for becoming a digital archivist? By answering these questions, we hope to expand the archival discussion on what it means to be an archivist in the digital age. What compelling intrinsic, evidential, or informational values are present in digital archival content that will draw professionals to the field? Are there other values inherent in digital content that are currently unexplored? In our poster, we will present our discussion of the topic, our survey design, and results we have at the time of the Institute. Thiemer, K. (2012). Honest tips for wannabe archivists.

Awareness of L1 and L2 word-formation mechanisms for the development of a more autonomous L2 learner

Unlike traditional approaches, new communicative trends disregard the role of word-formation mechanisms. They tend to focus on syntax and/or vocabulary without analyzing the mechanisms involved in the creation of lexical items. In this paper, based on the analysis of the use of prefixes by L2 learners in oral and written productions, as provided by the SULEC, we emphasize the advantages that word-formation awareness and knowledge may have for the learners in terms of production, creativity, understanding, autonomy, and proficiency. Through the teaching of word-formation learners may more easily decipher, decode and/or encode messages, create words they have never seen before, etc.

Mujeres, salud y profesiones sanitarias: revisión historiográfica y estudio de casos en la sanidad española contemporánea

La reconstrucción histórica de las prácticas de salud de las mujeres, tomando el caso español como campo de pruebas y modelo de análisis, constituye una de las líneas directrices de éste trabajo. Sobre la base de una importante cantidad de estudios empíricos, ajenos y propios, centrados muy en especial en el área de la enfermería, se puede delinear una imagen de conjunto sobre el trabajo sanitario de las mujeres, en el espacio geográfico y temporal objeto de nuestro estudio y contestar así a una serie de cuestiones en las que lo experto, la experiencia, la autoridad y los procesos de legitimación profesional están omnipresentes. La segunda de las vertientes abordadas es la de las mujeres como pacientes y usuarias de prácticas de salud. Las llamadas “patologías de mujeres” como la clorosis o la neurastenia y el significado histórico del protagonismo de las mujeres en las campañas y programas de educación sanitaria son otros tantos ejemplos que permiten desvelar discursos cargados de elementos ideológicos tradicionales pese a su aparente barniz de modernidad. Como principales conclusiones, hay que destacar la importancia que alcanzaron los discursos androcéntricos en temas concernientes a salud y mujer de forma global, o los más específicos como el del culto a la fecundidad para justificar unas tareas sociales diferentes y complementarias a las del hombre, además de señalar la conveniencia de explorar nuevos caminos a recorrer, tanto desde el punto de vista temático como en lo relativo a los recursos heurísticos.

Implementation Feasibility of a Digital Nervous System for the Construction Industry: For Efficient and Effective Information Management across the Project Lifecycle

The construction industry has long been considered as highly fragmented and non-collaborative industry. This fragmentation sprouted from complex and unstructured traditional coordination processes and information exchanges amongst all parties involved in a construction project. This nature coupled with risk and uncertainty has pushed clients and their supply chain to search for new ways of improving their business process to deliver better quality and high performing product. This research will closely investigate the need to implement a Digital Nervous System (DNS), analogous to a biological nervous system, on the flow and management of digital information across the project lifecycle. This will be through direct examination of the key processes and information produced in a construction project and how a DNS can provide a well-integrated flow of digital information throughout the project lifecycle. This research will also investigate how a DNS can create a tight digital feedback loop that enables the organisation to sense, react and adapt to changing project conditions. A Digital Nervous System is a digital infrastructure that provides a well-integrated flow of digital information to the right part of the organisation at the right time. It provides the organisation with the relevant and up-to-date information it needs, for critical project issues, to aid in near real-time decision-making. Previous literature review and survey questionnaires were used in this research to collect and analyse data about information management problems of the industry – e.g. disruption and discontinuity of digital information flow due to interoperability issues, disintegration/fragmentation of the adopted digital solutions and paper-based transactions. Results analysis revealed efficient and effective information management requires the creation and implementation of a DNS.

Sur les tests lisses d'ajustement dans le context des series chronologiques

La plupart des modèles en statistique classique repose sur une hypothèse sur la distribution des données ou sur une distribution sous-jacente aux données. La validité de cette hypothèse permet de faire de l’inférence, de construire des intervalles de confiance ou encore de tester la fiabilité du modèle. La problématique des tests d’ajustement vise à s’assurer de la conformité ou de la cohérence de l’hypothèse avec les données disponibles. Dans la présente thèse, nous proposons des tests d’ajustement à la loi normale dans le cadre des séries chronologiques univariées et vectorielles. Nous nous sommes limités à une classe de séries chronologiques linéaires, à savoir les modèles autorégressifs à moyenne mobile (ARMA ou VARMA dans le cas vectoriel). Dans un premier temps, au cas univarié, nous proposons une généralisation du travail de Ducharme et Lafaye de Micheaux (2004) dans le cas où la moyenne est inconnue et estimée. Nous avons estimé les paramètres par une méthode rarement utilisée dans la littérature et pourtant asymptotiquement efficace. En effet, nous avons rigoureusement montré que l’estimateur proposé par Brockwell et Davis (1991, section 10.8) converge presque sûrement vers la vraie valeur inconnue du paramètre. De plus, nous fournissons une preuve rigoureuse de l’inversibilité de la matrice des variances et des covariances de la statistique de test à partir de certaines propriétés d’algèbre linéaire. Le résultat s’applique aussi au cas où la moyenne est supposée connue et égale à zéro. Enfin, nous proposons une méthode de sélection de la dimension de la famille d’alternatives de type AIC, et nous étudions les propriétés asymptotiques de cette méthode. L’outil proposé ici est basé sur une famille spécifique de polynômes orthogonaux, à savoir les polynômes de Legendre. Dans un second temps, dans le cas vectoriel, nous proposons un test d’ajustement pour les modèles autorégressifs à moyenne mobile avec une paramétrisation structurée. La paramétrisation structurée permet de réduire le nombre élevé de paramètres dans ces modèles ou encore de tenir compte de certaines contraintes particulières. Ce projet inclut le cas standard d’absence de paramétrisation. Le test que nous proposons s’applique à une famille quelconque de fonctions orthogonales. Nous illustrons cela dans le cas particulier des polynômes de Legendre et d’Hermite. Dans le cas particulier des polynômes d’Hermite, nous montrons que le test obtenu est invariant aux transformations affines et qu’il est en fait une généralisation de nombreux tests existants dans la littérature. Ce projet peut être vu comme une généralisation du premier dans trois directions, notamment le passage de l’univarié au multivarié ; le choix d’une famille quelconque de fonctions orthogonales ; et enfin la possibilité de spécifier des relations ou des contraintes dans la formulation VARMA. Nous avons procédé dans chacun des projets à une étude de simulation afin d’évaluer le niveau et la puissance des tests proposés ainsi que de les comparer aux tests existants. De plus des applications aux données réelles sont fournies. Nous avons appliqué les tests à la prévision de la température moyenne annuelle du globe terrestre (univarié), ainsi qu’aux données relatives au marché du travail canadien (bivarié). Ces travaux ont été exposés à plusieurs congrès (voir par exemple Tagne, Duchesne et Lafaye de Micheaux (2013a, 2013b, 2014) pour plus de détails). Un article basé sur le premier projet est également soumis dans une revue avec comité de lecture (Voir Duchesne, Lafaye de Micheaux et Tagne (2016)).

Future of skills in Europe-Convergence or polarisation? CEPS Working Document No. 390, 27 February 2014

In this Working Paper, based on nearly 20 papers produced by the Centre for European Policy Studies, Slovak Governance Institute and the Conference Board Europe, we examine whether the current trends in the areas of education and skills are pushing the European Union, towards convergence or polarisation. We cover a wide range of questions related to this main issue. No easy answers, but several cross-cutting messages emerged from the research. We demonstrated that there is increasing complexity in what a ‘low-skilled’ person is and how well (or poorly) s/he fares in the labour market. There are undoubtedly powerful forces pushing for more polarisation, particularly in the labour market. Our research confirmed that early childhood education plays an important role, and it also appears to be increasingly uncontested as a policy prescription. However, the other frequently emphasised remedy to inequality – less selection in secondary education, particularly later division of children into separate tracks – is more problematic. Its effectiveness depends on the country in question and the target group, while education systems are extremely difficult to shift even on a long-term basis. A different, more-nuanced type of warning to policy-makers is delivered in our research on returns to higher education by field of study, which showed hidden rationality in how students choose their major.

British business and the Euro. ACES Cases No. 2008.2

During the Maastricht Treaty negotiations, the United Kingdom obtained an opt-out option on Economic and Monetary Union (EMU). When Tony Blair came to power, he promised there would be a referendum on the euro if the government decided it was in the national interest to join. Many believed Tony Blair intended to call and try to win a referendum on the euro. Therefore, in the late 1990s, the debate over the euro raged in Britain, filling the pages of the tabloids and the minds of many Britons. In this paper based on empirical research conducted in London in 2005-06, I investigate whether the business sector had a clear preference on the issue of British membership in the EMU and tried to influence the government‟s decision. I use Jeffry Frieden's model of interest group preferences regarding exchange-rate policies to develop hypotheses regarding the position of the business sector on the euro. Research findings reveal that the business sector was divided on the issue of euro membership exactly as Frieden's model predicts. However, the intensity of business preferences decreased overtime. By the end of Tony Blair's second term, the business sector had become neutral on the issue of the euro.

The impact of computer display height and desk design on 3D posture during information technology work by young adults

Computer display height and desk design to allow forearm support are two critical design features of workstations for information technology tasks. However there is currently no 3D description of head and neck posture with different computer display heights and no direct comparison to paper based information technology tasks. There is also inconsistent evidence on the effect of forearm support on posture and no evidence on whether these features interact. This study compared the 3D head, neck and upper limb postures of 18 male and 18 female young adults whilst working with different display and desk design conditions. There was no substantial interaction between display height and desk design. Lower display heights increased head and neck flexion with more spinal asymmetry when working with paper. The curved desk, designed to provide forearm support, increased scapula elevation/protraction and shoulder flexion/abduction.
