The goal was to analyze the explicit knowledge of those who have studied this concept in a regular IDC course in terms of the integration techniques as well as the meaning and the concept utilization. It has also been researched whether this knowledge reflected operational and structural conceptions in the sense applied by Anna Sfard (1991), whose theory this paper is based on. In her studies, the author postulates that abstract notions are conceivable in two completely different ways: structurally (as objects) and operationally (as processes). As an investigation means, it has been used a questionnaire containing nine questions and applied to two groups of a private school s math course in São Paulo city. One of the groups was constituted by students who have recently studied the notion of Integral, and the other group by students who went through the same studies one year before. In terms of the first group, the conclusion drawn up was that the students have incurred in several kinds of operational calculus mistakes, also the processes involving integral notion showed up but only sometimes, indicating a clear structural conception failure. These characteristics were not observed in the second group. It has been noticed that all researched students apparently had mobilized the structural concept considering they have applied the mathematical object to determine the area of even spaces in the function graph, but when facing those circumstances in which they had to reason to be able to apply the concept as an object they did not have enough assurance in terms of structural conception, and tried to take refuge in the algebra processes / Esta pesquisa buscou investigar os conhecimentos mobilizados por alunos, que estudaram o conceito de Integral, que permeia grande parte da disciplina Cálculo Diferencial e Integral (CDI) e que é fonte de dificuldades para os alunos. Buscouse analisar os conhecimentos explicitados por alunos que estudaram o conceito num curso regular de CDI, tanto no aspecto das técnicas de integração como no significado e na aplicação do conceito. Pesquisou-se, igualmente, se estes conhecimentos refletiam concepções operacionais e estruturais no sentido atribuído por Anna Sfard (1991), que fundamentou teoricamente este estudo. Em seu estudo, a autora postula que noções abstratas podem ser concebidas e duas maneiras fundamentalmente diferentes: estruturalmente (como objeto) e operacionalmente (como processo). Como instrumento de investigação foi utilizado um questionário com nove questões que foi aplicado a dois grupos de alunos do Curso de Matemática de uma instituição particular de São Paulo. Um deles constituídos por alunos que haviam estudado recentemente a noção de Integral e o outro, por estudantes que o fizera há cerca de um ano. Concluiu-se que, no caso do primeiro grupo, os alunos, além de terem apresentado variados tipos de equívocos em cálculos operatórios, os processos que envolvem a noção integral ora manifestam concebidos ora não, concorrendo para o prejuízo da concepção estrutural, o que não ocorreu no segundo grupo. Observou-se que a totalidade dos alunos pesquisados, aparentemente mobilizara a concepção estrutural, uma vez que aplicaram o objeto matemático para determinar a área de regiões planas sob o gráfico de funções, mas quando colocados numa situação particular em que se exigia uma reflexão para o emprego do conceito como objeto, eles não exibiram suficiente segurança em sua concepção estrutural, procurando refúgio em processos algébricos

Abstract The purpose of this study was to analyze cultural meanings associated with primary health center´s from customers’ point of view. Since 1972 the health center has been the most important place providing public health care. Nationally, customership development has been the main goal of primary health care. The purpose of this study was to determine the cultural meanings associated with the health center from customers’ point of view. The theoretical framework utilized in the study comprised the idea of new public service, the theory of organizational culture and a cultural model that allows understanding the health center, the cultural meanings conceptualized, and the interface between the customer and health care center. A three -phase empirical study was conducted using mixed methods. In the first phase, the cultural significance of the customer point of view was examined in document data (N=605), consisting of health care center -related writings in the Kaleva newspaper during the period 1972–1982. The second phase consisted of virtual anthropological data (N=338), i.e internet chat room writings from around 2010. The third phase was a questionnaire form, which formed part of the Northern Finland Birth Cohort 1966 study. It included a multiple choice questionnaire (N=3237) and open questions (N=200). Qualitative data (the empirical part of phases I, II, and partly III) were analyzed by inductive and deductive content analysis and text analysis. The quantitative data (the partly empirical phase III) were statistically analyzed. In the study, four cultural models were formed pertaining to the visible and hidden cultural meanings related to health centers from customers’ point of view: 1. The Melting Pot of Health Problems Model, highlighting the meanings between the organization and the customer, such as staff incarnation and individual activity associated with meanings, which on the other hand appeared contradictory. 2. The Low-Threshold Model, where the meanings are associated with service. The health center was considered a “rush center”, where the level of care varies, but the service was felt to harmonize with the trust-related meanings and was compared to the bedrock. 3. The Guessing Centre Model, which consisted of the beliefs and meanings associated with a health center waiting room or was described as a lottery, but which was on the other hand regarded as the center of rumors. 4. The Expected Future Model, where the meanings related to expectations concerning the future of the health care center, describing a generative and functional local health care centre with a set of values based on holisticity. The theoretical results provide new insight that helps understand phenomena on the interface between health care services and customers. Health center customers appear to be a cultural phenomenon, organized as cultural models. In health care, the new information generated in the study can be used in customers-oriented planning and development, education, health and applied cultural research. / Tiivistelmä Tutkimuksen tarkoituksena oli analysoida terveyskeskukseen liittyviä kulttuurisia merkityksiä perusterveydenhuoltopalveluiden asiakkaan näkökulmasta. Terveyskeskus on ollut vuodesta 1972 tärkein julkinen terveydenhoitopaikka. Valtakunnallisesti perusterveydenhuollon päätavoitteeksi on nostettu asiakkuuden kehittäminen. Tutkimustehtävänä oli selvittää, millaisia kulttuurisia merkityksiä terveyskeskukseen liittyy asiakkaan näkökulmasta. Tutkimuksen teoreettisessa viitekehyksessä hyödynnettiin hallintoteoreettista näkökulmaa, teoriaa organisaatiokulttuurista sekä kulttuurimallia. Terveyskeskukseen liittyviä kulttuurisia merkityksiä käsitteellistettiin reifikaatioon peilaten terveyskeskuksen ja asiakkaan välisen rajapinnan ymmärtämiseksi. Tutkimus jakautuu teoreettiseen ja empiiriseen osaan. Kulttuurisia merkityksiä asiakkaan näkökulmasta tutkittiin mixed methods -menetelmälähtöisesti kolmivaiheisen empiirisen aineiston pohjalta. Ensimmäinen vaihe koostui dokumenttiaineistosta (N=605), joka muodostui sanomalehti Kalevan julkaisemista terveyskeskukseen liittyvistä kirjoituksista vuosina 1972–1982. Toinen vaihe koostui virtuaaliantropologisesta aineistosta (N=338), joka käsitti internetin keskustelupalstojen kirjoituksia 2010-luvun taitteessa. Kolmas vaihe kerättiin kyselylomakkeella, joka oli osaotos Pohjoissuomen syntymäkohortti 1966:n tutkimusta. Se sisälsi monivalintakyselyn (N=3237) sekä avoimen kysymyksen (N=200). Laadulliset aineistot (empiirisen osan vaiheet I, II, osin III) analysoitiin induktiivisella ja deduktiivisella sisällön- ja tekstianalyysillä. Määrällinen aineisto (osin empiirisen aineiston osa III) analysoitiin tilastollisesti. Tutkimuksessa muodostettiin terveyskeskukseen liittyvistä näkyvistä ja piilotetuista kulttuurisista merkityksistä asiakkaan näkökulmasta neljä kulttuurimallia: 1. Vaivojen sulatusuunimalli, jossa korostuivat organisaation ja asiakkaan väliset merkitykset. Niitä olivat henkilöstöinkarnaatio ja asiakasaktiivisuus, jotka toisaalta näyttäytyivät ristiriitaisina. 2. Matalan kynnyksen malli, jossa merkitykset liittyivät palveluun. Terveyskeskus miellettiin ruuhkakeskukseksi, jossa hoidon taso vaihtelee, mutta toisaalta palveluun luotettiin ja sitä verrattiin peruskallioon. 3. Arvauskeskusmalli, joka muodostui uskomuksiin liittyvistä merkityksistä. Terveyskeskusta kuvailtiin odotushuoneeksi tai lottoriviksi, mutta joka toisaalta käsitettiin huhupuheiden keskiöksi. 4. Tulevaisuuden odotemalli, jossa merkitykset liittyivät tulevaisuuden odotuksiin. Terveyskeskus haluttiin nähdä tulevaisuudessa generatiivisena ja toimivana lähiasemana, jonka toimintakulttuurin arvopohja perustuisi holistisuuteen. Tutkimuksen teoreettisilla tuloksilla on uutuusarvoa terveyspalveluiden ja sen asiakkaan rajapinnan ilmiöiden ymmärtämiseksi. Terveyskeskuksessa asiakas on edelleen palvelujen tuottamisen kohde. Asiakkaan roolia tulee kehittää aktiiviseksi ja osallistuvaksi. Terveyskeskus on asiakkaille tärkeä ja se tulisi olla joustavasti lähellä myös tulevaisuudessa. Tutkimuksen tuottamaa tietoa voidaan hyödyntää terveydenhuollon asiakaslähtöisessä suunnittelu- ja kehittämistyössä, koulutuksessa sekä terveydenhuollon ja kulttuurintutkimuksen soveltavassa tutkimuksessa.

Music is perceived and described very subjectively by every individual. Nowadays, people often get lost in their steadily growing, multi-placed, digital music collection. Existing music player and management applications get in trouble when dealing with poor metadata that is predominant in personal music collections. There are several music information services available that assist users by providing tools for precisely organising their music collection, or for presenting them new insights into their own music library and listening habits. However, it is still not the case that music consumers can seamlessly interact with all these auxiliary services directly from the place where they access their music individually. To profit from the manifold music and music-related knowledge that is or can be available via various information services, this information has to be gathered up, semantically federated, and integrated into a uniform knowledge base that can personalised represent this data in an appropriate visualisation to the users. This personalised semantic aggregation of music metadata from several sources is the gist of this thesis. The outlined solution particularly concentrates on users’ needs regarding music collection management which can strongly alternate between single human beings. The author’s proposal, the personal music knowledge base (PMKB), consists of a client-server architecture with uniform communication endpoints and an ontological knowledge representation model format that is able to represent the versatile information of its use cases. The PMKB concept is appropriate to cover the complete information flow life cycle, including the processes of user account initialisation, information service choice, individual information extraction, and proactive update notification. The PMKB implementation makes use of SemanticWeb technologies. Particularly the knowledge representation part of the PMKB vision is explained in this work. Several new Semantic Web ontologies are defined or existing ones are massively modified to meet the requirements of a personalised semantic federation of music and music-related data for managing personal music collections. The outcome is, amongst others, • a new vocabulary for describing the play back domain, • another one for representing information service categorisations and quality ratings, and • one that unites the beneficial parts of the existing advanced user modelling ontologies. The introduced vocabularies can be perfectly utilised in conjunction with the existing Music Ontology framework. Some RDFizers that also make use of the outlined ontologies in their mapping definitions, illustrate the fitness in practise of these specifications. A social evaluation method is applied to carry out an examination dealing with the reutilisation, application and feedback of the vocabularies that are explained in this work. This analysis shows that it is a good practise to properly publish Semantic Web ontologies with the help of some Linked Data principles and further basic SEO techniques to easily reach the searching audience, to avoid duplicates of such KR specifications, and, last but not least, to directly establish a \"shared understanding\". Due to their project-independence, the proposed vocabularies can be deployed in every knowledge representation model that needs their knowledge representation capacities. This thesis added its value to make the vision of a personal music knowledge base come true.

The rapid and sustained development of the rural regions of South Africa continues to pose an extraordinary challenge to the development community of the country. Policy makers continue to be overwhelmed by the lack of development in the rural areas in spite of the various efforts made to develop them. A review of the publications and development plans of the study region indicates that the planners have for long been pre-occupied with taking limited perspectives of the development planning problems. Development plans have been conceived and implemented in terms of individual sectors instead of looking at their relations with other sectors and regions. This study seeks to make a contribution to the solution of the development problems of the rural areas of the former homeland regions by demonstrating how an integrated approach to the research process and to development planning could make a difference to the lives of the rural communities. This theme is illustrated with reference to the rural energy sector and its relations with the broader regional development problems, challenges and plans of the Sekhukhune district municipality of the Limpopo Province. / GEOGRAPHY / MA (GEOGRAPHY)

“A Shine of Truth in the ‘universal delusional context of reification’ (Theodor W. Adorno)” comprend sept chapitres, un prologue et un épilogue. Chaque partie se construit à deux niveaux : (1) à partir des liens qui se tissent entre les phrases contiguës ; et (2) à partir des liens qui se tissent entre les phrases non contiguës. Les incipit des paragraphes forment l’argument principal de la thèse. Le sujet de la thèse, Schein (apparence, illusion, clarté) est abordé de manière non formaliste, c’est à dire, de manière que la forme donne d’elle-même une idée de la chose : illusion comme contradiction imposée. Bien que le sujet de la thèse soit l’illusion, son but est la vérité. Le Chapitre I présente une dialectique de perspectives (celles de Marx, de Lukács, de Hegel, de Horkheimer et d'Adorno) pour arriver à un critère de vérité, compte tenu du contexte d’aveuglement universel de la réification ; c’est la détermination de la dissolution de l’apparence. Le Chapitre II présente le concept d’apparence esthétique—une apparence réversible qui s’oppose à l’apparence sociale générée par l’industrie de la culture. Le Chapitre III cherche à savoir si la vérité en philosophie et la vérité en art sont deux genres distincts de vérités. Le Chapitre IV détermine si l’appel à la vérité comme immédiateté de l’expression, fait par le mouvement expressionniste du 20e siècle, est nouveau, jugé à l’aune d’un important antécédent à l’expressionisme musical : « Der Dichter spricht » de Robert Schumann. Le Chapitre V se penche sur la question à savoir si le montage inorganique est plus avancé que l’expressionisme. Le Chapitre VI reprend là où Peter Bürger clôt son essai Theorie de l’avant-garde : ce chapitre cherche à savoir à quel point l’oeuvre d’art après le Dada et le Surréalisme correspond au modèle hégélien de la « prose ». Le Chapitre VII soutient que Dichterliebe, op. 48, (1840), est une oeuvre d’art vraie. Trois conclusions résultent de cette analyse musicale détaillée : (1) en exploitant, dans certains passages, une ambigüité dans les règles de l’harmonie qui fait en sorte tous les douze tons sont admis dans l’harmonie, l’Opus 48 anticipe sur Schoenberg—tout en restant une musique tonale ; (2) l’Opus 48, no 1 cache une tonalité secrète : à l'oeil, sa tonalité est soit la majeur, soit fa-dièse mineur, mais une nouvelle analyse dans la napolitaine de do-dièse majeur est proposée ici ; (3) une modulation passagère à la napolitaine dans l’Opus 48, no 12 contient l’autre « moitié » de la cadence interrompue à la fin de l’Opus 48, no 1. Considérés à la lumière de la société fausse, l’Allemagne des années 1930, ces trois aspects anti-organiques témoignent d’une conscience avancée. La seule praxis de vie qu’apporte l’art, selon Adorno, est la remémoration. Mais l’effet social ultime de garder la souffrance vécue en souvenir est non négligeable : l’émancipation universelle. / “A Shine of Truth in the ‘universal delusional context of reification’ (Theodor W. Adorno)” defends Adorno’s aesthetics as a theory of advanced, or avant-garde, artworks. Its seven chapters show that aesthetic experience implies liberation from illusion (Schein). Chapter I engages a dialectic of viewpoints to explain how different dialectical thinkers (Marx, Lukács, Hegel, Horkheimer, Adorno) have contributed to a criterion of truth adequate to today’s total delusional context of reification—determinate negation of illusion. Chapter II introduces the concept of artistic aesthetic illusion—a reversible illusion opposed to the social illusions of mechanical musical reproduction and of the culture industry. Chapter III examines the question of whether truth in philosophy is a different kind of truth than truth in art. Chapter IV considers whether truth in twentieth-century Expressionism is a new truth based on immediate expression, in light of an important precedent for Expressionism in Robert Schumann’s “Der Dichter spricht.” Chapter V determines whether inorganic montage is more advanced than Expressionism. Chapter VI takes up a parting suggestion of Peter Bürger: to treat artworks after Dada and Surrealism on the model of “prose” in Hegel’s aesthetics. Chapter VII pursues the idea that Dichterliebe, op. 48, (1840) by Robert Schumann is a true artwork. Three results emerge from this close musical analysis: (1) exploiting, on occasion, an ambiguity in the rules for figuration that permits all twelve tones in the harmony, Schumann anticipates Schoenberg; (2) Op. 48, No. 1 is in a hidden key: to all appearances, its key is either A major or F-sharp minor, but its secret key is the Neapolitan region applied to C-sharp major; (3) the other “half” of the cadence with which Op. 48, No. 1 breaks off suddenly may be found in a brief applied-Neapolitan passage in No. 12. The thesis argued is that the antiorganicity in such a work is advanced with regard to the false reality of 1930s Germany and the place of organicity therein. According to Adorno, the only life-praxis afforded by art is remembrance. But the social effect of remembering social suffering is considerable when the Here-and-Now is its own justification.

Ce travail vise à mettre en avant une éthique du futur à l’ère des technologies du vivant à partir de la biologie philosophique de Hans Jonas en passant au crible a priori les fondements des technosciences. Jonas estime que le problème n’est pas la technique elle-même qui soit en cause mais l’identité qu’elle accorde à l’homme dans cette logique instrumentale envahissante, en d’autres termes, le matérialisme réductionniste. Le problème aussi n’est pas les effets visibles inquiétants et désastreux de la technique mais l’ontologie qu’elle inspire. Outre les manifestations réelles de destruction qu’elle génère, c’est l’être qu’elle confère ou plus exactement dont elle prive l’homme qui est catastrophique. L’homme finit par se considérer comme un fond exploitable. Il s’agira donc de formuler une éthique qui a pour soubassement une biologie philosophique qui récuse une anthropologie mécaniste d’inspiration matérialiste, une ontologie du pas-encore qui fonde les sciences modernes. Réduire l’homme à des lois physico-chimiques, c’est violer notre individualité. Le métabolisme est la preuve de notre individuation. Dans la matière, gît l’esprit. Au-delà de l’anthropomorphisme qui se dégage, l’homme est le seul animal symbolisant doué d’une conscience réflexive. Une responsabilité politique s’impose pour protéger l’intégrité et l’image de l’homme à l’ère des technologies du vivant qui espèrent améliorer ou modifier l’espèce humaine. Mais cette responsabilité politique qui promeut « un marxisme désenchanté » ne tardera pas à renforcer voire devenir une rationalité instrumentale et idéologique à l’image du lyssenkisme. Une autre responsabilité s’impose : une responsabilité scientifique formulée par Charles De Koninck qui interpelle et invite les scientifiques à ne pas sacrifier l’être humain par leurs recherches sur l’autel des subventions financières, du dualisme au relent matérialiste. La science, dans son élan est invitée à tenir compte du facteur « humain ». Cette responsabilité scientifique va au-delà des règles de bonnes pratiques et déontologiques des comités et des expertises scientifiques. Elle nécessite une éducation scientifique pour une science citoyenne pour éviter une science aveugle et idéologique. Bref, à partir de ces paradigmes, nous voulons montrer que les rêves de l’amélioration, de l’augmentation des performances de l’espèce humaine sont des chimères. / This work intends to highlight the ethics of the future in the era of technologies of the living being starting from Jonas and after scrutinizing in the first place the foundations of technosciences that is the emerging reductionism. Just like Heidegger, Jonas is of the view that the problem is not technology itself that it should be blamed but the identity it grants man in that overwhelming instrumental logic, in other words, reductionist materialism. The issue is neither the alarming, disastrous and visible effects of technology but the ontology it generates. Beside true manifestations of destruction it generates, it is the being it confers, or more specifically from which it deprives man who is catastrophic. It is important henceforth to evaluate that reductionist science in terms of a philosophical biology that will become basis to ethics and evaluation criterion for convergent technologies. It is about ethics that has philosophical biology for basis, which challenges materialism-inspired mechanist anthropology, a not-yet ontology that founds modern sciences. Reducing man to laws that rule Physics is violating our individuality. Metabolism (the other name for ontology in Jonas’s terms) is evidence of our individuation. Beyond the anthropomorphism that appears, man remains the only symbolizing animal, the only one to be gifted with introspective consciousness. From that symbolic dimension proceeds culture along with phenomena of self-consciousness. A political responsibility becomes imperative from that philosophical biology to protect man’s integrity and image in the era of technologies of the living that intend to improve or modify human race on the behalf of perfectibility and from processes of reductionist mechanism. But that political responsibility that promotes “a disillusioned Marxism” will not be long in reinforcing, even becoming an instrumental and ideological rationality in the image of lyssenkism. Another form of responsibility becomes imperative: a scientific responsibility framed by Charles De Koninck who calls out to and invites scientists to not give up the human being through their research on the altar of financial subsidies, materialist stench dualism. Science, in its speed is invited to take into account the “human” factor. That scientific responsibility goes beyond behaviorist and deontological rules of scientific committees and expertise. It requires a scientific education for a citizen-based science in order to avoid a blind and ideological science. In a nutshell, from those paradigms, we intend to show that dreams of improvement and increase of achievements of human race are mere illusion.

Cette recherche porte sur les activités mentales réalisées lors d’un geste invasif d’une infirmière sur un malade. Il s’agit de comprendre ce qui l’encourage à rendre objet le corps de ce dernier alors que les nouvelles pédagogies prônent de rendre le malade acteur de ses soins. Cette étude vise à caractériser le cheminement intellectuel qu’impose ce geste en termes d’opérationnalité et de motivation à agir pour résoudre les tensions entre ce que les infirmières pensent devoir faire au regard de leur prescription médicale et des recommandations professionnelles, mais aussi ce qu’elles peuvent réellement faire en situation.Les résultats obtenus permettent d’identifier que l’infirmière s’autohypnose en se concentrant sur sa respiration et en s’invectivant en utilisant le « tu » d’une manière positive et en inhibant ses émotions afin de ne courir aucun risque émotionnel et de vivre son geste dans une version simplifiée de la réalité. / This thesis is all about the mental activities realized during an invasive gesture of a nurse on a patient. It deals with the question what makes the nurse to consider as an object the patient’s body wheras the new pedagogies advocate turning a sick person actor of his own care. The aim of this study is to characterize the intellectual path imposed by this gesture in terms of operational effectiveness and motivation to act. It is about solving the tensions between what the nurses think they have to do – with regards to their prescription and professional recommendations – and what they really can do in situation.
