Abordar la infancia desde el enfoque de derechos (ED) implica una lectura de los derechos de los cuales los niños, niñas y adolescentes (NNA) son titulares y de las acciones estatales que se implementan para viabilizar el ejercicio concreto de ellos. Esta perspectiva exige comprender los contenidos de las políticas púb,el grado de participación que se les asigna y los sentidos que ellas toman en términos de progresividad de los derechos. Los cambios de concepción de la infancia desde la Convención Internacional de los Derechos del Niño (CIDN) y los cambios legislativos interpelan al Estado y la sociedad a modificar la visión hegemónica. Nuestra hipótesis gira alrededor de las siguientes considerac.: se han producido algunas modificaciones en las políticas y acciones estatales, aún no se dan las transformaciones necesarias de las lógicas institucionales y de los operadores que estimulen la participación de NNA en el ámbito escolar. Esto se visualiza en la ausencia de análisis cuali de los contenidos de las acc. y la falta de ftes estadísticas específicas, que muestren la orientac.de los contenidos en los principios de la protecc.integral. Estos presupuestos plantean interrogantes que delimitan el problema de investigación: ¿cómo se construye y reconstruye el ejercicio de la ciudadanía a través de la participación de los NNA, en su paso por la escuela, y cuáles son las lógicas institucionales que habilitan u obstaculizan ese ejercicio? Y ¿cuáles son los recursos institucionales que permitan que los programas y acciones redunden en el ejercicio efectivo de los derechos?.Obj.gral: Describir, analizar e interpretar la progresividad en el ejercicio de los derechos de participación e informacióin que tienen los adolescentes en escuelas secundarias de la cd de Cba, durante 2005 / 2010, para promover espacios públicos de construcción de ciudadanía.

The issue of children from the rights focus implies a reading of the rights in which children and adolescents are the holders and the state actions that are implemented to enable the exercise of them. This perspective requires understanding the contents of the public policies, the participation level that is assigned, and the senses that they take in terms of rights progressivity of. The conception changes about children since the International Convention on the Rights of the Child and legislative changes challenge to the State and society to modify hegemony vision. Our hypothesis revolves around the following considerations: there have been some public policies and state actions changes, but they not turn out, yet, transformations in logical institutional and actors whose are encourages children participation in school. This could be reflects in the absence of qualitative analysis in the actions contents and the lack of sources specific statistics, that will be showing the control of the principal contents of integral protection. These, raise the questions that delimit our problem research: how is built citizenship exercise through children and adolescent’s participation in the school, and what are the institutional logical that empowers or turns difficult that exercise? And What are the institutional resources that make possible the effective exercise of the rights, through different programs and actions?. General Objective: To describe, analyze and interpret exercise progressivity participation and information rights that have the adolescents in secondary schools in Córdoba City during 2005 / 2010, in order to promote public spaces for the construction of citizenship. It will analyze three schools in Cordoba, provincial public school, national public school and private school. . Obj. Specifics: To analyze the formal and informal participative practices in the schools selected. - To apply quantitative and qualitative indicators of the “Indicators System for Infa

A preliminary account on the normal development of the imaginai discs in holometabolic Insects is made to serve as an introduction to the study of the hereditary homoeosis. Several facts and experimental data furnished specially by the students of Drosophila are brought here in searching for a more adequate explanation of this highly interesting phenomenon. The results obtained from the investigations of different homoeotic mutants are analysed in order to test Goldschmidt's theory of homoeosis. Critical examination of the basis on which this theory was elaborated are equally made. As a result from an extensive theoretical consideration of the matter and a long discussion of the most recent papers on this subject the present writer concludes that the Goldschmidt explanation of the homoeotic phenomena based on the action of diffusing substances produced by the genes, the "evocators", and on the alteration of the normal speed of maturation of the imaginai discs equally due to the activity of the genes, could not be proved and therefore should be abandoned. In the same situation is any other explanation like that of Waddington or Villee considered as fundamentally identical to that of Goldschmidt. In order to clear the problem of homoeosis in terms which seem to put the phenomenon in complete agreement with the known facts the present writer elaborated a theory first published a few years ago (1941) based entirely on the assumption that the imaginai discs are specifically determined by some kind of substances, probably of chemical nature, contained in the cytoplam of the cells entering in the consti- tution of each individual disc. These substances already present in the blastem of the egg in which they are distributed in a definite order, pass to different cells at the time the blastem is transformed into blastoderm. These substances according to their organogenic potentiality may be called antenal-substance, legsubstance, wing-substance, eye-substance, etc. The hipoderm of the embryo resulting from the multiplication of the blastoderm cells would be constituted by a series of cellular areas differing from each other in their particular organoformative capacity. Thus the hypoderm giving rise to the imaginai discs, it follows that each disc must have the same organogenic power of the hypodermal area it came from. Therefore the discs i*re determinated since their origin by substances enclosed in the cytoplasm of their cells and consequently can no longer alter their potentiality. When an antennal disc develops into a leg one can conclude that this disc in spite of its position in the body of the larva is not, properly speaking, an antennal disc but a true leg disc whose cells instead of having in their cytoplasm the antennal substance derived from the egg blastem have in its place the leg-substance. Now, if a disc produces a tarsus or an antenna or even a compound appendage partly tarsus-like, partly antenna-like, it follows tha,t both tarsal and antennal substances are present in it. The ultimate aspect of the compound structure depends upon the reaction of each kind of substance to the different causes influencing development. For instance, temperature may orient the direction of development either lowards arista or tarsus, stimulating, or opposing to the one or the other of these substances. Confering to the genes the faculty of altering the constitution of the substances containing in the cytoplasm forming the egg blastem or causing transposition of these substances from one area to another or promoting the substitution of a given substance by a different one, the hereditary homoeocis may be easily explained. However, in the opinion of the present writer cytoplasm takes the initiative in all developmental process, provoking the chromosomes to react specifically and proportionally. Accordingly, the mutations causing homoeotic phenomena may arise independently at different rime in the cytoplasm and in the chromosomes. To the part taken by the chromosomes in the manifestation of the homoeotic characters is due the mendalian ratio observed in homoeotic X normal crosses. Expression, in itself, is mainly due to the proportion of the different substances in the cells of the affected discs. Homoeotic phenomena not presenting mendelian ratio may appear as consequence of cytoplasmic mutation not accompanied by chromosomal mutation. The great variability in the morphology of the homoeotic characteres, some individual being changed towards an extreme expression of the mutant phenotype while others in spite of their homozigous constitution cannot be distinguished from the normal ones, strongly supports the interpretation based on the relative proportion of the determining substances in the discs. To the same interpretation point also asymetry and other particularities observed in the exteriorization of the phenomenon. In conformity with this new conception homoeosis should not prove homology of Insect appendages (Villee 1942) since a more replacement of substances may cause legs to develop in substitution of the wings, as it was already observed (requiring confirmation in the opinion of Bateson 1894, p. 184) and no one would conclude for the homology of these organs in the usual meaning of the term.

The appeal to ideas as causal variables and/or constitutive features of political processes increasingly characterises political analysis. Yet, perhaps because of the pace of this ideational intrusion, too often ideas have simply been grafted onto pre-existing explanatory theories at precisely the point at which they seem to get into difficulties, with little or no consideration either of the status of such ideational variables or of the character or consistency of the resulting theoretical hybrid. This is particularly problematic for ideas are far from innocent variables – and can rarely, if ever, be incorporated seamlessly within existing explanatory and/or constitutive theories without ontological and epistemological consequence. We contend that this tendency along with the limitations of the prevailing Humean conception of causality, and associated epistemological polemic between causal and constitutive logics, continue to plague almost all of the literature that strives to accord an explanatory role to ideas. In trying to move beyond the current vogue for epistemological polemic, we argue that the incommensurability thesis between causal and constitutive logics is only credible in the context of a narrow, Humean, conception of causation. If we reject this in favour of a more inclusive (and ontologically realist) understanding then it is perfectly possible to chart the causal significance of constitutive processes and reconstrue the explanatory role of ideas as causally constitutive.

La douleur est fréquente en milieu de soins intensifs et sa gestion est l'une des missions des infirmières. Son évaluation est une prémisse indispensable à son soulagement. Cependant lorsque le patient est incapable de signaler sa douleur, les infirmières doivent se baser sur des signes externes pour l'évaluer. Les guides de bonne pratique recommandent chez les personnes non communicantes l'usage d'un instrument validé pour la population donnée et basé sur l'observation des comportements. A l'heure actuelle, les instruments d'évaluation de la douleur disponibles ne sont que partiellement adaptés aux personnes cérébrolésées dans la mesure où ces personnes présentent des comportements qui leur sont spécifiques. C'est pourquoi, cette étude vise à identifier, décrire et valider des indicateurs, et des descripteurs, de la douleur chez les personnes cérébrolésées. Un devis d'étude mixte multiphase avec une dominante quantitative a été choisi pour cette étude. Une première phase consistait à identifier des indicateurs et des descripteurs de la douleur chez les personnes cérébrolésées non communicantes aux soins intensifs en combinant trois sources de données : une revue intégrative des écrits, une démarche consultative utilisant la technique du groupe nominal auprès de 18 cliniciens expérimentés (6 médecins et 12 infirmières) et les résultats d'une étude pilote observationnelle réalisée auprès de 10 traumatisés crâniens. Les résultats ont permis d'identifier 6 indicateurs et 47 descripteurs comportementaux, vocaux et physiologiques susceptibles d'être inclus dans un instrument d'évaluation de la douleur destiné aux personnes cérébrolésées non- communicantes aux soins intensifs. Une deuxième phase séquentielle vérifiait les propriétés psychométriques des indicateurs et des descripteurs préalablement identifiés. La validation de contenu a été testée auprès de 10 experts cliniques et 4 experts scientifiques à l'aide d'un questionnaire structuré qui cherchait à évaluer la pertinence et la clarté/compréhensibilité de chaque descripteur. Cette démarche a permis de sélectionner 33 des 47 descripteurs et valider 6 indicateurs. Dans un deuxième temps, les propriétés psychométriques de ces indicateurs et descripteurs ont été étudiés au repos, lors de stimulation non nociceptive et lors d'une stimulation nociceptive (la latéralisation du patient) auprès de 116 personnes cérébrolésées aux soins intensifs hospitalisées dans deux centres hospitaliers universitaires. Les résultats montrent d'importantes variations dans les descripteurs observés lors de stimulation nociceptive probablement dues à l'hétérogénéité des patients au niveau de leur état de conscience. Dix descripteurs ont été éliminés, car leur fréquence lors de la stimulation nociceptive était inférieure à 5% ou leur fiabilité insuffisante. Les descripteurs physiologiques ont tous été supprimés en raison de leur faible variabilité et d'une fiabilité inter juge problématique. Les résultats montrent que la validité concomitante, c'est-à-dire la corrélation entre l'auto- évaluation du patient et les mesures réalisées avec les descripteurs, est satisfaisante lors de stimulation nociceptive {rs=0,527, p=0,003, n=30). Par contre la validité convergente, qui vérifiait l'association entre l'évaluation de la douleur par l'infirmière en charge du patient et les mesures réalisés avec les descripteurs, ainsi que la validité divergente, qui vérifiait si les indicateurs discriminent entre la stimulation nociceptive et le repos, mettent en évidence des résultats variables en fonction de l'état de conscience des patients. Ces résultats soulignent la nécessité d'étudier les descripteurs de la douleur chez des patients cérébrolésés en fonction du niveau de conscience et de considérer l'hétérogénéité de cette population dans la conception d'un instrument d'évaluation de la douleur pour les personnes cérébrolésées non communicantes aux soins intensifs. - Pain is frequent in the intensive care unit (ICU) and its management is a major issue for nurses. The assessment of pain is a prerequisite for appropriate pain management. However, pain assessment is difficult when patients are unable to communicate about their experience and nurses have to base their evaluation on external signs. Clinical practice guidelines highlight the need to use behavioral scales that have been validated for nonverbal patients. Current behavioral pain tools for ICU patients unable to communicate may not be appropriate for nonverbal brain-injured ICU patients, as they demonstrate specific responses to pain. This study aimed to identify, describe and validate pain indicators and descriptors in brain-injured ICU patients. A mixed multiphase method design with a quantitative dominant was chosen for this study. The first phase aimed to identify indicators and descriptors of pain for nonverbal brain- injured ICU patients using data from three sources: an integrative literature review, a consultation using the nominal group technique with 18 experienced clinicians (12 nurses and 6 physicians) and the results of an observational pilot study with 10 traumatic brain injured patients. The results of this first phase identified 6 indicators and 47 behavioral, vocal and physiological descriptors of pain that could be included in a pain assessment tool for this population. The sequential phase two tested the psychometric properties of the list of previously identified indicators and descriptors. Content validity was tested with 10 clinical and 4 scientific experts for pertinence and comprehensibility using a structured questionnaire. This process resulted in 33 descriptors to be selected out of 47 previously identified, and six validated indicators. Then, the psychometric properties of the descriptors and indicators were tested at rest, during non nociceptive stimulation and nociceptive stimulation (turning) in a sample of 116 brain-injured ICLI patients who were hospitalized in two university centers. Results showed important variations in the descriptors observed during the nociceptive stimulation, probably due to the heterogeneity of patients' level of consciousness. Ten descriptors were excluded, as they were observed less than 5% of the time or their reliability was insufficient. All physiologic descriptors were deleted as they showed little variability and inter observer reliability was lacking. Concomitant validity, testing the association between patients' self report of pain and measures performed using the descriptors, was acceptable during nociceptive stimulation (rs=0,527, p=0,003, n=30). However, convergent validity ( testing for an association between the nurses' pain assessment and measures done with descriptors) and divergent validity (testing for the ability of the indicators to discriminate between rest and a nociceptive stimulation) varied according to the level of consciousness These results highlight the need to study pain descriptors in brain-injured patients with different level of consciousness and to take into account the heterogeneity of this population forthe conception of a pain assessment tool for nonverbal brain-injured ICU patients.

En partant d'une étude ethnographique dans un laboratoire engagés dans la conception et la réalisation de micro et nanosystèmes, l'article rend compte de la manière dont ces objets sont amenés à l'existence, mais aussi de la fragilité de cette existence d'être technologique. Confronté à de nombreux échecs, les chercheurs en viennent à douter de leur faisabilité technologique, de leur capacité à maintenir l'intérêt des industriels pour ces objets, voire même du sens de l' histoire technologique. Cette histoire, qu' ils croyaient évoluer inéluctablement des microsystèmes vers les nanosystèmes, semble brutalement s'arrêter, voir s'inverser. Les nanosystèmes ne seraient alors qu'un leurre, une illusion plutôt qu'une nouvelle catégorie de technologie. L'existence-même de l'objet est devenue problématique. En suivant les chercheurs, ingénieurs et techniciens au travail, l'article rend compte de la technogénèse comme exploration des modes d'existence des êtres technologiques.

OBJECTIVES: To investigate the development of the ureterovesical junction in rats. METHODS: A total of 110 albino rats (50 prenatal and 60 newborn) with a gestation of 21 days were studied at the age of 17 days after conception until 5 days after birth. The lower urinary tract was microdissected. Microphotography (110 animals), histologic examination (44 animals), and scanning electron microscopy (66 animals) of the ureterovesical junction were performed. Urea and creatinine from the amniotic fluid of 20 fetuses and from the urine of 10 neonates were measured. RESULTS: At day 17 after conception, separate penetration of the mesonephric duct and ureter into the wall of the urogenital sinus was observed. Continuity between the lumen of the ureter and the urogenital sinus was established on day 19 after conception. The straight passage of the intramural ureter into the urogenital sinus at day 17 after conception changed to the definitive L-shape with a vertical entry into the bladder on day 5 after birth. In the distal ureter, the change of the mesenchymal tissue into immature smooth muscle was first observed at birth, and the muscle became mature on the fifth postnatal day. At birth, Waldeyer's sheath was recognized. The creatinine and urea levels were stable prenatally (average 22.4 micromol/L and 6.88 mmol/L, respectively) and rose significantly postnatally (average 133 micromol/L and 32.65 mmol/L, respectively). CONCLUSIONS: The attachment of the ureter to the urogenital sinus and later to the bladder, the modification of its passage, and its mobility within Waldeyer's sheath may be essential in preventing vesicoureteral reflux. The production of urine and its flow does not seem to be the trigger of ureteral smooth muscle formation.

The present thesis is a contribution to the debate on the applicability of mathematics; it examines the interplay between mathematics and the world, using historical case studies. The first part of the thesis consists of four small case studies. In chapter 1, I criticize "ante rem structuralism", proposed by Stewart Shapiro, by showing that his so-called "finite cardinal structures" are in conflict with mathematical practice. In chapter 2, I discuss Leonhard Euler's solution to the Königsberg bridges problem. I propose interpreting Euler's solution both as an explanation within mathematics and as a scientific explanation. I put the insights from the historical case to work against recent philosophical accounts of the Königsberg case. In chapter 3, I analyze the predator-prey model, proposed by Lotka and Volterra. I extract some interesting philosophical lessons from Volterra's original account of the model, such as: Volterra's remarks on mathematical methodology; the relation between mathematics and idealization in the construction of the model; some relevant details in the derivation of the Third Law, and; notions of intervention that are motivated by one of Volterra's main mathematical tools, phase spaces. In chapter 4, I discuss scientific and mathematical attempts to explain the structure of the bee's honeycomb. In the first part, I discuss a candidate explanation, based on the mathematical Honeycomb Conjecture, presented in Lyon and Colyvan (2008). I argue that this explanation is not scientifically adequate. In the second part, I discuss other mathematical, physical and biological studies that could contribute to an explanation of the bee's honeycomb. The upshot is that most of the relevant mathematics is not yet sufficiently understood, and there is also an ongoing debate as to the biological details of the construction of the bee's honeycomb. The second part of the thesis is a bigger case study from physics: the genesis of GR. Chapter 5 is a short introduction to the history, physics and mathematics that is relevant to the genesis of general relativity (GR). Chapter 6 discusses the historical question as to what Marcel Grossmann contributed to the genesis of GR. I will examine the so-called "Entwurf" paper, an important joint publication by Einstein and Grossmann, containing the first tensorial formulation of GR. By comparing Grossmann's part with the mathematical theories he used, we can gain a better understanding of what is involved in the first steps of assimilating a mathematical theory to a physical question. In chapter 7, I introduce, and discuss, a recent account of the applicability of mathematics to the world, the Inferential Conception (IC), proposed by Bueno and Colyvan (2011). I give a short exposition of the IC, offer some critical remarks on the account, discuss potential philosophical objections, and I propose some extensions of the IC. In chapter 8, I put the Inferential Conception (IC) to work in the historical case study: the genesis of GR. I analyze three historical episodes, using the conceptual apparatus provided by the IC. In episode one, I investigate how the starting point of the application process, the "assumed structure", is chosen. Then I analyze two small application cycles that led to revisions of the initial assumed structure. In episode two, I examine how the application of "new" mathematics - the application of the Absolute Differential Calculus (ADC) to gravitational theory - meshes with the IC. In episode three, I take a closer look at two of Einstein's failed attempts to find a suitable differential operator for the field equations, and apply the conceptual tools provided by the IC so as to better understand why he erroneously rejected both the Ricci tensor and the November tensor in the Zurich Notebook.

Résumé « Laennec CD-ROM » est un programme d'enseignement assisté par ordinateur (EAO) pour l'apprentissage de la sémiologie en pneumologie. Son idée de base était de fournir aux étudiants et aux enseignants un outil d'apprentissage interactif et richement illustré des différents gestes cliniques en pneumologie. Primé en 1994 pour la meilleure contribution multimédia à la European Academie Software Award (EASA-94), il représente un bon exemple de ce qui pouvait être réalisé alors. Mais l'histoire de l'EAO remonte aux années 1960. Un bref historique de l'EAO permet de mieux situer ce programme dans le temps. Et comme tout outil pédagogique, celui-ci s'appuie sur une représentation de comment l'apprentissage se fait. Trois courants pédagogiques majeurs sont présentés. Le behaviorisme ou comportementalisme pour qui le savoir est transmis pour être stocké tel quel par l'apprenant. Pour le cognitivisme, par contre, le contenu est retravaillé par l'apprenant avant d'être stocké, et ce traitement de l'information peut être influencé. Quant au constructivisme, celui-ci prédit que le savoir est construit à l'aide des contenus mis à disposition, mettant en avant l'importance du contexte dans lequel l'apprentissage se fait. Mais indépendamment des orientations pédagogiques, une des question fondamentale est : un enseignement assisté par ordinateur est-il meilleur qu'un enseignement traditionnel ? Étonnamment, il n'est pas facile de répondre à cette question, malgré de . nombreuses études sur le sujet. « Laennec CD-ROM » est constitué de trois parties. Un tutoriel présentant de manière didactique l'inspection, la palpation, la percussion et l'auscultation pulmonaire. Il est richement illustré par des dessins, photos, vidéo et sons d'auscultation. La deuxième partie présente sept patients souffrant de maladies pulmonaires fréquentes. Ce volet du cd-rom permet d'appliquer à des cas les principes de sémiologie appris dans le tutoriel. Pour chaque patient, une anamnèse, un examen clinique (avec des sons d'auscultation) et une série d'examens para-cliniques (imagerie, laboratoire) permettent à l'utilisateur de poser un diagnostic différentiel et un traitement. La troisième partie du cd-rom est un petit historique sur René, Théophile, Hyacinthe Laennec, l'inventeur du stéthoscope. Pour terminer, la conception et la réalisation du programme sont présentées en détail ainsi que sa validation et son utilisation.

Résumé Ce travail a commencé avec une confrontation entre les pensées de P. Ricoeur et E. Levinas sur le thème du rapport à autrui, cette confrontation portant particulièrement sur la place accordée par Levinas, dans son éthique, au thème de la vulnérabilité (ainsi que sur celui de la passivité), tandis que P. Ricoeur reste, selon moi, prioritairement un philosophe de l'activité et qui met, dans la question du rapport à autrui, l'accent sur la reconnaissance de l'autre dans l'empire de ses capacités. Ce débat, et les points qui retenaient en particulier mon attention, m'ont semblé pouvoir être inséré dans le contexte plus large d'une opposition entre éthique de l'autonomie et éthique de la vulnérabilité sur la base de lectures que j'effectuais par ailleurs dans le domaine des éthiques féminines, ou de ce que l'on appelle les éthiques du « care ». Les éthiques féminines, qui se sont développées les 30 dernières années, veulent revenir sur ce qu'elles identifient comme le modèle anthropologique de la modernité, qui privilégie une approche de l'homme en termes d'activité, de rationalité et d'autonomie au mépris d'autres traits comme la passivité, l'affectivité, la dépendance ou la vulnérabilité. Sans nier la rationalité ou l'autonomie de l'homme, elles veulent plutôt compléter une image qu'elles considèrent comme étant incomplète. Sur la base de leur anthropologie alternative, les auteurs qui appartiennent à ce courant proposent une nouvelle définition de l'éthique. Les éthiques du « care » se situent d'une manière générale dans une relation critique avec les éthiques de la justice comme avec les conceptions de l'agent et du patient moral héritées de la philosophie kantienne. Disons brièvement que, plutôt que de faire de l'autonomie et de son respect l'axe de leur réflexion morale, les éthiciennes du « care » insistent sur la signification morale de nos rapports de responsabilité ou de sollicitude à l'égard des personnes vulnérables. Dans la première partie de ma thèse, je reviens sur la genèse de la notion d'autonomie dans la philosophie morale et politique de la pré-modernité, en mettant le développement de ce concept en lien non seulement avec ce que J. Scheewind appelle les « morales de l'autogouvernement », mais aussi avec la naissance des philosophies du sujet et un mouvement général d'intériorisation des sources morales. J'essaye ensuite de dégager le sens de l'idée d'autonomie, sur la base de la notion de liberté positive élaborée par Berlin, avant de distinguer ses différentes significations (autonomie politique, personnelle, morale/autonomie procédurale vs substantielle, autonomie comme capacité, comme droit ou comme idéal). Je me concentre particulièrement sur la conception hiérarchique de l'autonomie personnelle développée par Frankfurt et Dworkin, avant de revenir à la conception kantienne de l'autonomie morale. Je consacre ensuite une section aux conceptions relationnelles de l'autonomie, ce qui me permet de faire le lien avec le thème de la vulnérabilité. Pour le développement historique de cette notion dans la pensée contemporaine, j'insiste, outre sur les éthiques du « care », sur les développements de la bioéthique et la philosophie de H. Jonas. Après un travail de définition du concept de vulnérabilité, j'élabore les éléments d'une éthique de la vulnérabilité que j'essaie d'articuler à la notion d'autonomie. Dans la deuxième partie, je confronte les éthiques de Ricoeur et de Levinas dans la perspective de l'opposition autonomie/vulnérabilité, en montrant leurs limites respectives.

That financial matters did not constrain industrial takeoff in the UK is generally accepted in the historical literature; in contrast, contemporary empirical analyses have found evidence that financial development can be a causal determinant of economic growth. We look to reconcile these findings by concentrating on a particular aspect of industrialising UK where inefficiencies in finance could have had bite: The finance of physical infrastructures. We document the historical record and develop the importance of spatial disaggregation and spillovers in both technological and financial development. We develop a simple model that captures the nature of infrastructure finance within a theory of endogenous growth where financial costs are endogenous. We argue that the conception of the finance-growth nexus as a largely static, aggregative phenomenon misses out a good deal of complexity and we relate that complexity to a number of implications for regulation of both financial systems and the emergence of infrastructures

In this article, we analyze a multilingual interaction in a students' working group and hypothesize a correlation between management of languages in interaction and leadership. We consider Codeswitching as one of the most relevant observables in multilingual interaction and attempt to analyze how it is used by speakers. After a brief presentation of three theoretical and analytical conceptions of Code-switching in interaction (Auer, Mondada & Myers Scotton), we define Code-switching as an interactional, strategical, multilingual resource exploited by speakers to achieve various interactionaland non interactional goals. We then show in two CA-like analysis how multilingual strategical resources occur in the interactional practices of the analyzed working group, and how they are exploited by speakers in order to organize interaction, work, tasks, and to construct one's leadership.We also consider the metadiscourses of the students about their own practices and multilingualism in general, in order to confront them to their actual multilingual practices. We draw the hypothesis that discrepancies observed between metadiscourses and practices can be explained through the development of (meta)discourses showing a unilingual conception in describing multilingual practices.

La problemática de la investigación se plantea en el contexto de la filosofía trascendental de Kant, en relación al modo en que es en general posible para nosotros representarnos el ámbito de la moralidad. Nuestra comprensión natural o preteórica del funcionamiento del lenguaje parece llevarnos a entender el significado de nuestras palabras en términos de la relación que se establece entre el signo lingüístico y el objeto: nuestros términos lingüísticos están en el lugar del objeto extralingüístico a que refieren y que constituye su significado. A nuestro modo de ver, la afirmación kantiana relativa a que todo nuestro conocimiento comienza con la experiencia, es decir, con aquello que procede de los sentidos, parece estar apuntando a esta intuición fundamental. Ahora bien, la cuestión que cabe plantearse es: de acuerdo con este modelo de significación, ¿cuál es el significado de nuestros términos morales? Si, con Kant, aceptamos que el concepto de deber moral exige el cumplimiento (u omisión) incondicionado de una acción y que, precisamente por las exigencias de universalidad y necesidad que le son inherentes, tal concepto es inderivable de la experiencia, cabe preguntarse cuál es el significado del concepto de deber en sentido moral (y, en general, de los términos morales) y de qué manera somos capaces de representárnoslo. Mi investigación ha pretendido esclarecer precisamente en qué sentido debe entenderse la afirmación kantiana de que en la reflexión sobre la corrección moral de nuestras acciones, para representarnos las exigencias de universalidad y necesidad que son propias del concepto de deber moral, nos servimos analógicamente del concepto de naturaleza, así como analizar la plausibilidad de la propuesta kantiana misma.

It has been alleged that J M Keynes, quoting in the General Theory a passage from J S Mill's Principles, misunderstood the passage in question and was therefore wrong to cite Mill as an upholder of the 'classical' proposition that 'supply creates its own demand'. We believe that, although Keynes was admittedly in error with respect to, so-to-say, the 'letter' of Mill's exposition, he did not mislead readers as to the 'substance' of Mill's conception. The purpose of this paper is to demonstrate that J S Mill did indeed stand for a 'classical' position, vulnerable to Keynes's critique as developed in the General Theory.

The purpose of this paper is to highlight the curiously circular course followed by mainstream macroeconomic thinking in recent times. Having broken from classical orthodoxy in the late 1930s via Keynes’s General Theory, over the last three or four decades the mainstream conventional wisdom, regressing rather than progressing, has now come to embrace a conception of the working of the macroeconomy which is again of a classical, essentially pre-Keynesian, character. At the core of the analysis presented in the typical contemporary macro textbook is the (neo)classical model of the labour market, which represents employment as determined (given conditions of productivity) by the terms of labour supply. While it is allowed that changes in aggregate demand may temporarily affect output and employment, the contention is that in due course employment will automatically return to its ‘natural’ (full employment) level. Unemployment is therefore identified as a merely frictional or voluntary phenomenon: involuntary unemployment - in other words persisting demand-deficient unemployment - is entirely absent from the picture. Variations in aggregate demand are understood to have a lasting impact only on the price level, not on output and employment. This in effect amounts to a return to a Pigouvian conception such as targeted by Keynes in the General Theory. We take the view that this reversion to ideas which should by now be obsolete reflects not the discovery of logical or empirical deficiencies in the Keynes analysis, but results rather from doctrinaire blindness and failure of scholarship on account of which essential features of the Keynes theory have been overlooked or misrepresented. There is an urgent need for a critical appraisal of the current conventional macroeconomic wisdom.
