We can find it in some researches, defended dissertations and annual reports about computer literacy monitoring results – the importance and necessity of digital literacy is undeniable. However, the methods of the digital literacy competence assessments are still reliable. In this paper, we describe the most possible reasons of changing the content of ECDL syllabus version 4 and the ways of how the ECDL certification program must change. The goal of this paper is to suggest the original methodology of ECDL syllabus version item comparison; to provide the tendencies of how the ECDL syllabus content must change; to prepare a list of requirements for ECDL syllabus version 5 and basic informatics study program item coordination. The method of ECDL syllabus version item comparison was demonstrated by performing the research of ECDL syllabus version 4 to 5 item comparison in two ways: by analyzing the content of ECDL syllabus version 4 and syllabus version 5 and by comparing them together. Two aspects measured the results: ECDL syllabus version 4 status to ECDL syllabus version 5 (the fact of changing the content: “New”, “Changed”, “Split”, “Merge”, “Same”) and the reason of changing the content of ECDL syllabus version 4 (“Clarity”, “Quality”, “Currency”). Finally, we were able to prescribe how the ECDL syllabus version 4 was changed, how many new requirements were involved and how the ECDL certification program must change. At the end we...

The use of screen devices is marked by different features and settings in daily life of modern society. This dissertation deals with the prospect of the use of these devices by the juvenile portuguese public and the question of social use of time. Through a mixed approach that includes three complementary dimensions: a systematic review of literature to understand better the concepts worked on the "screen-daily" and the social use of time, focus groups aimed at a thorough reflection from the experience and vision of young people about the problem and questionnaire survey on a larger sample of young people. This empirical work took place throughout the year 2016. Through the literature review process and the analysis of the collected empirical data, it was possible to verify the plurality of uses that Portuguese youth have for screen objects and the forms of sociability in the matters of man-object mediation.

Full textAbstract:
Customer relationship management (CRM) or the electronic version of CRM (eCRM) helps organisations to focus on their customers and to take advantage of the knowledge about them to increase the organisation's market share, sales and profit. Due to globalisation and stiff competition, organisations have changed their focus from business-centric to customer-centric, from customer acquisition to customer retention and from mass marketing to target marketing. There are many definitions of eCRM, but for the purpose of this thesis, eCRM is discussed from an information system perspective. This research investigates the factors that might influence the success of eCRM system implementation in a large organisation in the United Kingdom. In this research, system implementation refers to the use of the system in the organisation .. This research analyses the internal and external factors that influence th~ success of implementing the system, which include system factors, organisation factors, management factors, staff factors, and customer factors. The research has also discovered additional contributing factors as well as affecting factors, which include use of the eCRM system as a monitoring and productivity tool, and competitors, regulators and inconsistencies in the work process. This qualitative research was conducted using a case study in a large contact centre organisation in North-West UK. The research methods include personal experience, participant observation, open-ended questions and document analysis. The output of the research is a blueprint that details all the activities and work processes involved in using the eCRM system. A Ripple model is then constructed from this blueprint, which shows the inter-dependency and inter-relation of the contributing and inhibiting factors. The research concludes by highlighting the key contributions stemming from the case study, and discussing future research work that can be extended from this thesis.

ECDL programa skirta kompiuterinio raštingumo įgūdžiams formuoti ir tobulinti. Šios programos pasiekimas yra tai, kad nustatytas standartas kompiuterio vartotojo žinioms ir įgūdžiams sertifikuoti. ECDL sertifikavimas iš pradžių buvo atliekamas rankiniu būdu. Vėliau buvo pereita prie kompiuterizuoto testavimo, tam sukuriant specialias testavimo sistemas. ECDL programoje įgytų įgūdžių įvertinimui Lietuvoje naudojama testavimo sistema dirba su interneto klientais. Teisę prie jos jungtis turi tik įgaliotieji ECDL testavimo centrai. Testavimo sistemos užduotys yra keleto tipų: pagrįstos tiesioginiu atlikimu, imitavimu, spragtelėjimo ir tempimo, „tiesa/netiesa“ pasirinkimu bei daugybiniu pasirinkimu. Iki šiol nėra spręsta problema, ar efektyviai realizuotoje testavimo sistemoje atliekamas įvairių užduočių tipų tikrinimas, ar testuojant atsižvelgiama į žmogaus įgūdžių kokybę. Kadangi ECDL testų tikrinimas vykdomas tiek rankiniu būdu, tiek automatizuotu būdu, todėl būtų labai naudinga išanalizuoti įvairius testavimo būdus ir įvertinti rankinio ir automatizuoto testavimo būdų galimybes kokybės požiūriu.

O enfoque principal deste estudo incidiu nas inquietações relativas à modernização da indumentária dos pivots de programas de informação televisivos portugueses, em conexão com o contexto global (com incidência na sociedade ocidental) e segundo os códigos profissionais do vestuário. Foram examinados casos de programas informativos de referência, assim como as respectivas estações televisivas, a fim de identificar e contribuir para a minimização das desconexões entre o styling dos pivots nacionais relativamente às práticas das grandes cadeias de notícias estrangeiras. O mundo em que vivemos valoriza cada vez mais a imagem dos grandes protagonistas de interação com o público, à semelhança de todas as outras áreas de grande visibilidade pública, visto que estes são considerados como o elemento central nos blocos de informação estabelecendo em primeira mão a ligação primordial com o público. Assim, toda a comunicação visual possui um papel preponderante na relação entre telespectador - programa. No encerramento desta investigação e em função dos resultados decorrentes deste processo, desenvolveu-se uma proposta de Styling Editorial/Vídeo Editorial, que reflecte as conclusões deste estudo cujo principal objectivo é actualizar a Imagem dos Apresentadores Portugueses, em articulação com o set - design.
ABSTRACT: The focus oh the current research is connected with the Fashion Design, studies, and more specifically on all the questions concerning the Fashion Styling field. The main focus oh this study is the concerns involved with the contemporization of image of anchors operating in portuguese news televisions shows aiming to connect them to the global context and mainly in the eastern world following, however less orthodox professional dress codes. We will reputable news shows and anchors in order to identify gaps and contributing on the minimization of desconnections. In the modern society, we increasingly value the appearance of all the public figures who interact with us and so pushing us towards the establishment of “private” trust connections between viewers and anchors, the faces of those who everyday let us know in a serious way, what is going on around the world. The conclusions achieved during the all research process aim to support the development of a video and editorial “ghost” proposal which main objective is contributing the update of the Portuguese news anchors appearance.

Full textAbstract:
The T2K (Tokai to Kamioka) experiment is an off-axis long-baseline neutrino oscillation experiment with a baseline of 295 km to the Super-Kamiokande far detector. The near detec- tor, ND280, measures the flux and energy spectra of electron and muon neutrinos 280m from the muon neutrino beam source. Electromagnetic calorimeters constructed from lead and plas- tic scintillator bars cover the largest active area in ND280. The most downstream calorimeter is the Downstream Electromagnetic Calorimeter (DS-ECal). This thesis details aspects of the construction and calibration of the DS-ECal. Construction of the DS-ECal and quality assurance of the scintillator bars was performed at Lancaster University. All scintillator bars that were selected for optical quality assurance tests were accepted for use in the construction of the DS-ECal. Each bar that was tested was shown to have a light yield within ~2δ of the mean light yield of 35.9 ± 4.9 photoelectrons per minimum- ionising particle, measured at 66 cm from the scintillator bar end with three wavelength-shifting fibres coupled to a photomultiplier readout. Cosmic ray data collected at CERN, upon the successful construction of the DS-ECal, was used to develop a simple track-selection algorithm that reconstructed the position of charge deposits in the DS-ECal. The resulting attenuation profiles of all bars have been demonstrated to be consistent with one another within uncertainties using a developed quadruple-exponential function that describes the attenuation of the detected light along the length of the DS-ECal scintillator bars both quantitatively and qualitatively. The attenuation length of light traveling along the length of scintillator bars within the calorimeter has been measured to be 341 ± 90 cm. This is consistent with expected values of the order of 350 cm for Yll WLS fibres. The Tokai (in - situ) and CERN cosmic ray data are also shown to be consistent with within approximately 1 % as calculated from the mean most probable value of a convoluted Landau-Gaussian distribution of charge hits at several positions along the bars for all channels in the detector combined. The DS-ECal is currently collecting neutrino data for inclusion in the T2K 20l0a physics run and is in good working order with only 11 dead channels from a total of 3400.

Full textAbstract:
Tese de Doutoramento em Informática apresentada à Universidade de Trás-os-Montes e Alto Douro em 2013.Nas duas últimas décadas, assistimos ao desenvolvimento de um número crescente de técnicas, designadas por tone mapping operators (TMO), para reprodução de imagens com elevada gama dinâmica (high dynamic range – HDR) em ecrãs tradicionais. Apesar de recentemente terem surgido TMO que têm em conta a característica específica de cada dispositivo de visualização, nenhum desses algoritmos foi desenvolvido especificamente para dispositivos com ecrã pequeno (DEP). Assim, nesta tese foi realizado um estudo sobre a visualização de imagens HDR em DEP, tendo como propósito a proposta de soluções para a melhoria da sua visualização. Inicialmente foi realizada uma avaliação dos TMO atualmente existentes que mostrou que os DEP com tamanho limitado, resolução e profundidade de cor, exigem uma investigação específica para encontrar ou criar uma solução adequada. Esse estudo permitiu, também, identificar um conjunto de características dos TMO que precisam ser enfatizadas para obter imagens mapeadas com uma maior fidelidade nos DEP, especialmente o realce dos detalhes. Com base nesse estudo foi proposta uma solução para visualização de imagens HDR em DEP, que tem por base a construção de um TMO híbrido. O TMO proposto, tendo por base um qualquer TMO, tenta melhorar os detalhes das imagens mapeadas com o TMO original. Através da realização de experiências psicofísicas foi demonstrado que este novo TMO produz melhores resultados em DEP que os obtidos com o TMO original. Apesar de ter sido desenvolvido um protótipo em J2ME do novo TMO, a sua atual implementação ainda é pouco eficiente para a realização de testes diretamente em DEP. Em conclusão, com este trabalho é identificada a problemática da visualização de imagens HDR em DEP, sendo apontadas sugestões de como melhorar esse processo e fica ainda a proposta de um novo TMO.

PACIENTES E M?TODOS: Foram revisados retrospectivamente os prontu?rios de 733 pacientes com hipertens?o na gravidez; 424 foram consideradas com pr?-ecl?mpsia e 52, com ecl?mpsia. RESULTADOS: Pacientes com ecl?mpsia e pr?-ecl?mpsia foram diferentes em aspectos demogr?ficos, cl?nicos e laboratoriais. As pacientes com eclampsia eram mais jovens, tinham menos gesta??es e menor peso. Os valores das press?es sist?lica e diast?lica foram significativamente mais elevados no grupo das ecl?mpticas. A protein?ria foi significativamente maior no grupo das pacientes com eclampsia, bem como a ocorr?ncia de s?ndrome HELLP. Tamb?m apresentaram ?cido ?rico s?rico mais elevado, maior incid?ncia de cesarianas, e desfechos perinatais mais desfavor?veis. A idade materna abaixo de 16 anos foi fator de risco para a ocorr?ncia de eclampsia. A combina??o de ?cido ?rico s?rico materno igual ou maior que 6 mg/dL e ?ndice protein?ria/creatinin?ria igual ou superior a 5 demonstrou forte associa??o com a ocorr?ncia de ecl?mpsia, demonstrado pela regress?o log?stica. CONCLUS?O: A combina??o de ?cido ?rico s?rico materno igual ou superior a 6 e ?ndice protein?ria/creatinin?ria em amostra igual ou superior a 5 est?o fortemente associados ao desenvolvimento de crise ecl?mptica e a interrup??o da gesta??o deve ser considerada, dentro de um contexto cl?nico completo, mesmo na presen?a de prematuridade.

Previous issue date: 2004-04-15T00:00:00ZThis study investigates the existences of differences in the consumer behavior related to ECR values. The main objective of the study is to analyze if the same group of consumers attribute different importer to ECR values, with or without price, and if theses differences were related with socials status. Three hundred self-administrate questionnaires where collect in São .Paulo city focusing two categories of grocery goods. The main results of the study were: a) there were differences in the behavior of the consumers not only in relation with product categories but also related to the importance of the ECR value; b) differences in the consumer behavior related between social classes; c) Different groups of consumer emerged when ECR value were considered. d) Price represents a significant attribute to consumer.
Este trabalho destinou-se a investigar a existência de diferenças no comportamento do consumidor diante dos valores ofertados por ECR - Efficient Consumer Response, considerando duas categorias de produtos diferentes. O principal objetivo era verificar se um mesmo grupo de consumidores atribuía importâncias diferentes para os valores ofertados por ECR com ou sem preço e se estas diferenças também existiam entre classes sociais. Também se investigou a existência de um processo de escolha próprio, por parte dos consumidores que avaliavam os valores de ECR e preço. Foram realizados 300 levantamentos, junto a moradores da Grande São Paulo, tendo sido utilizado um instrumento de pesquisa auto-preenchível. Como principais resultados encontrou-se: a) diferenças no comportamento dos consumidores tanto em relação às categorias de produto consideradas, como em relação à importância atribuída a cada valor ofertado, com ou sem preço. b) diferenças no comportamento dos consumidores de classes sociais diferentes, quando consideravam as mesmas categorias de produtos com ou sem preço; c) um processo de escolha próprio a determinados grupos de consumidores e diferentes quando se consideravam um e outro produto, e d) o valor preço com importância destacada.

Durant cette thèse nous avons caractérisé et amélioré une nouvelle source de rayons X avec unplasma ECR (résonance cyclotronique électronique) permettant de générer des électronsénergétiques de 10 à 120 keV, qui vont ensuite produire le rayonnement X par freinage(bremsstrahlung). Les améliorations de l’installation ont permis d’obtenir une source stable, pouvantfonctionner une journée entière de travail (huit heures) sans arrêt. Dans la première partie de l’étudeexpérimentale on a étudié et déterminé les paramètres optimaux de la source : la pression, lapuissance micro-onde et la configuration magnétique sur le rayonnement X du plasma. Nous avonségalement confirmé la localisation des électrons énergétiques sur un anneau due à la configurationmagnétique. L’intensité trop faible et la zone d’émission non ponctuelle du rayonnement plasma, nepermettant pas l’utilisation de la source à plasma, une cible a été insérée sur la trajectoire desélectrons énergétique pour résoudre ces deux problèmes.Le principal avantage de notre source par rapport aux tubes X, est l’absence de haute tension (20 à400 kV). Pour chauffer les électrons, nous utilisons une onde de 2,45 GHz, qui est la fréquenceindustrielle autorisée dans les fours à micro-ondes, délivrée par un magnétron. Les éléments simplesqui composent notre source donne un coût plus faible qu’un système classique de tubes X, dûprincipalement au prix élevé du générateur HT pour les tubes X. De plus, nous n’avons pas besoind’un vide très poussé car, à la différence des tubes X, la source ECRX fonctionne avec une pressionrésiduelle de 0,1mPa. Et enfin notre source est compacte ce qui la rend facilement transportable. Lesapplications de cette source sont nombreuses comme la radiologie, la stérilisation et le contrôle nondestructif industrielDuring this thesis we have characterised and developed a new X-ray source with an ECR plasma(electron cyclotron resonance) generating energetic electrons from 10 to 120 keV, which will emit adeceleration radiation (the Bremsstrahlung). The improvements of the installation permit to obtain astable source, which can work during one day (eight hours) without stop. In first part of theexperimental study we have studied and determined the optimal parameters of the source: pressure,micro-wave power and the magnetic configuration on the X radiation of the plasma. We also confirmedthe localisation of the energetic electron on a ring due to the magnetic configuration. The low intensityand the non punctual emission size of the X radiation, don’t allow the use of the source, so a target isinserted in the trajectory of the energetic electron to solve these two weaknesses.The main advantage of our source compared with X-ray tubes, is the absence of high voltage (20 to400 kV). For heating the electron, we use a 2,45 GHz wave, that is the industrial frequency authorizedfor the micro-wave oven, delivered by the magnetron. The simple elements that compose our sourceare less expensive than the classical X-ray tubes, due to mainly the high cost of the X-ray generator.Moreover, we don’t need a high vacuum, mandatory for the X-ray tubes; an ECRX operates at aresidual pressure of 0,1 mPa. And finally, we have a compact source. Applications will be various frommedical, like radiological, sterilization, to non-destructive industrial control

Full textAbstract:
An almost universal instability in high pressure plasmas is the Neoclassical
Tearing Mode (NTM). NTMs are driven by local perturbations in
the current density and result in magnetic island like deformations of the
magnetic topology. They can be stabilized by compensating the current
perturbations with local electron cyclotron resonance heating (ECRH) or
with non-inductive current drive (ECCD). The modified Rutherford equation
describes the nonlinear evolution of tearing modes as determined by
various contributions to the local current density pertubation. An extensive
investigation of the two terms representing the stabilizing effects from
ECRH and ECCD have been made resulting in accurate description of both
terms. The results of this model can now be compared to the experimental
observations. For this purpose, an extensive data set exists from the past
experiments on tearing mode stabilization by ECRH and ECCD on TEXTOR.
The properly benchmarked model can then be used to predict the
effectiveness of ECRH and ECCD for NTM stabilization on International
Thermonuclear Experimental Reactor (ITER). In addition, a number of
predictions on the effects of ECRH and ECCD on the growth of the NTM
have been made on the basis of crude approximations to the ECRH and
ECCD tems in the modified Rutherford equation. These predictions can
now be checked against the more accurate expressions obtained.

Full textAbstract:
ECRS is a program for the detailed simulation of extensive air shower initiated by high energy cosmic ray particles. In this dissertation work, a Geant4 based ECRS simulation was designed and developed to study secondary cosmic ray particle showers in the full range of Earth's atmosphere. A proper atmospheric air density and geomagnetic field are implemented in order to correctly simulate the charged particles interactions in the Earth's atmosphere. The initial simulation was done for the Atlanta (33.460 N , 84.250 W) region. Four different types of primary proton energies (109, 1010, 1011 and 1012 eV) were considered to determine the secondary particle distribution at the Earth's surface. The geomagnetic field and atmospheric air density have considerable effects on the muon particle distribution at the Earth's surface. The muon charge ratio at the Earth's surface was studied with ECRS simulation for two different geomagnetic locations: Atlanta, Georgia, USA and Lynn Lake, Manitoba, Canada. The simulation results are shown in excellent agreement with the data from NMSU-WIZARD/CAPRICE and BESS experiments at Lynn Lake. At low momentum, ground level muon charge ratios show latitude dependent geomagnetic effects for both Atlanta and Lynn Lake from the simulation. The simulated charge ratio is 1.20 ± 0.05 (without geomagnetic field), 1.12 ± 0.05 (with geomagnetic field) for Atlanta and 1.22 ± 0.04 (with geomagnetic field) for Lynn Lake. These types of studies are very important for analyzing secondary cosmic ray muon flux distribution at the Earth's surface and can be used to study the atmospheric neutrino oscillations.

Full textAbstract:
The Large Hadron Collider (LHC) at CERN have a capacity to produce protonproton collisions with an energy of 14 TeV. Four particle detectors are included in the LHC with the purpose to detect all the particles that are created in the collisions. In one of these detectors are scintillating lead tungstate crystals used, to detect the energy of photons and electrons created in the collisions. The energy is detected by measuring of the emitted light from the scintillating crystals. As much knowledge as possible about the optical properties of the crystals are desired to be able to analyze the acquired data from the crystals.
This thesis work presents some techniques used for the characterization of the optical properties for the crystals. It also presents measurements done on the decay time of lead tungstate crystals and on the temperature influence to the light yield from the crystals. These measurement results are in addition used in an attempt to estimate how big influence the Cherenkov radiation has to the total amount of emitted light from the scintillating crystals.
The influence from the temperature to the light yield is around −2.02 %/◦C for BTCP and around −1.75 %/◦C for SIC1. No conclusions could been drawn concerning the influence from the Cherenkov radiation to the total amount of emitted light from the temperature measurements.The decay time measurements showed an influence from the Cherenkov radiation to the total amount of emitted light of; 8 % for crystal 1003, 47 % for crystal 1002 and 19 % for crystal 1001.
1BTCP (Bogoroditsk Technical Chemical Plant) and SIC (Shanghai Institute of Ceramics) are the two different crystal production facilities used for the production of the crystals.

Previous issue date: 2006-06-28Nesta disserta??o se questionam alguns aspetos muito espec?ficos da perspectiva antropoc?ntrica das teorias ambientais. ? perspectiva antropoc?ntrica, criticamos somente desde um ponto de vista elementar pois n?o ? o principal objetivo deste trabalho e, ademais, ? poss?vel atualmente dispor de revis?es t?cnicas muito mais profundas desde uma concep??o ecoc?ntrica. O eixo central deste trabalho ? uma cr?tica reflexiva das concep??es antropoc?ntricas e das antropom?rficas como paradigma epistemol?gico. N?o apostamos nos paradigmas, eles s?o incomensur?veis, n?o podem ser medidos ou avaliados por motivo de sua ordem de grandeza ou de sua import?ncia, por isso, preferimos o contexto humano (din?mico) ao paradigma te?rico (est?tico) um contexto de racionalidade (ecol?gica) que constr?i permanentemente (conatus) a harmonia entre o bi?tico e o abi?tico do mundo. Propomos uma perspectiva ecoc?ntrica e uma racionalidade ecol?gica fundada numa vis?o hol?stica do mundo e que n?o cinda natureza e cultura, pois entre elas n?o h? distin??o, assim como n?o cinda a realidade existente entre os seres humanos e o mundo como unidade integral. Em definitivo, uma racionalidade ecol?gica n?o pensa um direito ambiental como um produto cultural espec?fico para assegurar as rela??eshumanas num cronotopos social e ambiental definido assim como a ser definido (gera??es futuras), um direito como regula??o como regula??o e garantia das conquistas sociais obtidas nos espa?os de lutas pelos direitos humanos, no caso direitos humanos ambientais, sim que o pensa, como um direito da natureza e da cultura (um produto cultural adjetivado da natureza/cultura), onde a justifica??o encontra-se no cumprimento dos deveres e obriga??es com a dignidade da vida. Com estes pressupostos desenhamos nossa concep??o de um Estado Socioambiental e Democr?tico de Direito.

The present work was carried out at the Atol das Rocas (3? 51 S; 33? 49 W), the only atoll of the South Atlantic and the first Brazilian marine protected area. It was guided by the following hypothesis: the composition of the fish communities varies in agreement with the position of the pools; in other words, with or without permanent ocean connection. To test the validity of this hypothesis, the fish abundance was estimated in the connected pools (Barretinha/Barreta Falsa) and unconnected ones (Cemiteriozinho/?ncoras), carrying an ecological characterization of the fishes that inhabit these pools. Additionally, the structural complexity of the sampled places was also evaluated intending to verify the variations of the abundance and diversity of fishes in function to this factor. By the fact of this research was being carried out through the limits of a conservation unit, the samples was realized using visual census techniques. The results generated through uni and multivariate analytic techniques allowed the evidence that decisive factor in the density, richness and diversity variations of fishes are linked to the substratum type (Hard / Soft bottom) and not by the fact that the pool are or are not connected permanently to the ocean. In relation to the structural complexity; 58% of the variations in the diversity of fishes were attributed to changes in the structural complexity, while 12% of the variations in the abundance were attributed to the structural complexity
Este trabalho realizado no Atol das Rocas (3? 51 S; 33? 49 W), o ?nico atol do Atl?ntico Sul e a primeira ?rea marinha protegida brasileira, foi norteado pela hip?tese de que: a composi??o das comunidades de peixes varia de acordo com a posi??o das piscinas; ou seja, com ou sem conex?o permanente com o oceano. Para testar a validade desta hip?tese foram realizadas estimativas da abund?ncia de peixes em piscinas conectadas (Barretinha/Barreta Falsa) e n?o conectadas com oceano (Cemiteriozinho/?ncoras), realizando uma caracteriza??o ecol?gica dos peixes que habitam estas piscinas. Adicionalmente a complexidade estrutural dos locais amostrados tamb?m foi avaliada, com intuito de verificar varia??es da abund?ncia e diversidade de peixes em fun??o deste fator. Pelo fato desta pesquisa ter sido realizada dentro dos limites de uma unidade de conserva??o, as amostragens foram realizadas atrav?s do censo visual. Um total de 56 esp?cies foram identificadas no estudo piloto e durante as amostragens 48 destas foram observadas. Os resultados gerados atrav?s de t?cnicas anal?ticas uni e multivariadas permitiram constatar que o fator determinante nas varia??es de densidade, riqueza e diversidade dos peixes ? o tipo de substrato (consolidados/n?o consolidados) e n?o fato das piscinas estarem ou n?o conectada permanentemente com oceano. Com rela??o ? complexidade estrutural; 58% das varia??es na diversidade de peixes s?o atribu?das a mudan?as na complexidade estrutural enquanto que 12% das varia??es na abund?ncia s?o atribu?dos a este fator

In this thesis we deal with a class of composed networks that are formed by two tree networks, TP and TA, whose end points touches each other through a bipartite network BPA. We explore this network using a functional approach. We are interested in what extend the topology, or the structure, of TX (X = A or P) determines the links of BPA. This composed structure is an useful model in evolutionary biology, where TP and TA are the phylogenetic trees of plants and animals that interact in an ecological community. We use in this thesis two cases of mutualist interactions: frugivory and pollinator networks. We analyse how the phylogeny of TX determines or is correlated with BPA using a Monte Carlo approach. We use the phylogenetic distance among elements that interact with a given species to construct an index κ that quantifies the influence of TX over BPA. The algorithm is based in the assumption that interaction matrices that follows a phylogeny of TX have a total phylogenetic distance smaller than the average distance of an ensemble of Monte Carlo realizations generated by an adequate shuffling data. We find that the phylogeny of animals species has an effect on the ecological matrix that is more marked than plant phylogeny

Full textAbstract:
Gastric acid plays an important role in digesting food (especially proteins), iron absorption, and destroying swallowed micro-organism. N4 is secreted by the oxyntic parietal cells. Its secretion is regulated by endocrine, neurocrine and paracrine mechanisms. Gastrin released from the antral G cell is the principal physiological stimulus of gastric acid secretion. The ECL cell is accepted as the source of histamine participating in the regulation o f acid secretion and is functionally and trophically controlled by gastrin. Amidated gastrin is the main biologically active form of gastrin, and its main precursor Gly-G-17 was formerly thought to be without any biological activity. However, recent studies raised the possibility of both secretory and trophic effects of Gly-gastrin. No Glt-G-17 receptor has been cloned yet. In paper I, the effect of this peptide on gastric acid secretion was examined in the totally isolated vascularly perfused rat stomach. This study clearly demonstrates that the administration of Gly-G-17 in high doses was followed by an increase in histamine release and gastric acid output. Moreover, Gly-G-17 induced gastric acid secretion was completely inhibited by the H2 receptor antagonist ranitidine. Thus, the natural interpretation of these data is that Gly-G-17 is a weak gastrin agonist, interacting with the CCK-2 receptor on the ECL cell, resulting in a subsequent release of histamine, which in turn stimulates the parietal cell. The stomach is also regulated by nerves, principally by the vagal nerves. The gastric neurons contain various neuropeptides, some of them, such ad PACAP are known to influence gastric acid secretion. In paper II, PACAP was studied with respect to the effect on gastric acid secretion using totally isolated vascularly perfused rat stomachs, chronic fistula rats and isolated parietal cells. The results show that its stimulatory effects on gastric acid secretion is mainly due to an increase in histamine release from the ECL cell. PACAP is a powerful stimulator of histamine release from the ECL cell.
As mentioned above, aside from its stimulatory effect on gastric acid secretion, gastrin also has a trophic effect on the oxyntic mucosa, especially on the ECL cell. A definite connection has been found between hypergastrinemia and gastric carcinoids both in rats and humans. Moreover, some of the gastric adenocarcinomas in rodents with hypergastrinemia have been reclassified as ECLomas. However, spontaneous gastric ECL omas in laboratory animals are extremely rare. Japanese cotton rats (Sigmodon hispidus) have a very high incidence of gastric carcinomas occurring predominately in females, and which we previously showed, were associated with achlorhydria and hypergastrinemia. In paper III, the gastric carcinomas in cotton rats are described further. Particularly the oxyntic mucosa outside the tumour is shown to contain normal parietal cells indicating a normal ability to produce acid.
Long-term potent inhibitors of acid secretion resulting in secondary hypergastrinemia will induce ECL cell hyperplasia and probably carcinoids. Accordingly, the induction of ECL-cell hyperplasia and carcinoids remains a topic of considerable concern, especially in young individuals. Furthermore, the stomach is important for the absorption of calcium. Achlorhydria has been described as causing impairment of calcium absorption. Thus, a mechanism related to gastric acid secretion has been postulated to be involved in osteopenia developing in patients after gastric resection. More specifically, a postulated peptide, gastrocalcin, has been hypothesised to exist in the ECL cell. We therefore examined the effect of long-term hypergastrinemia secondary to drug induced hypoacidity with respect to bone developing in young male rats (paper IV). Long-term potent acid inhibition evoked a marked increase in plasma gastrin levels, leading to enlargement of oxyntic mucosa with ECL cell hyperplasia. However, body weight and bone mineral density were reduced in the hypergastrinemic young male rats. These findings do not support the hypothesis that the ECL cell plays a role in bone metabolism.
Finally, anaesthetized animal models have been widely used to study gastric acid secretion. However, anaesthetic agents also affect acid output. Anaesthetic agents naturally reduce acid secretion by interaction with neural activity, but could also play a role by affecting the function of the different cells taking part in the regulatory chain of acid secretion as well as the parietal cell itself. In paper V, the totally isolated vascularly perfused rat stomach was used to study the effect of anaesthetic agents on the ECL cell and the parietal cell functions. The results indicate that anaesthetic agents can also affect gastric acid secretion through a direct inhibitory action on parietal cells and ECL cells.

Ce travail s'inscrit dans le cadre du projet pmc#2, organise conjointement entre l'universite pierre marie curie et la compagnie ibm-france. Dans un premier temps, on s'interesse a la simplification des methodes d'enseignement de l'ecl en vue de la conception de circuitss integres bipolaires sur matrice prediffusee. Il s'agit alors d'une modelisation du delai en ecl permettant de determiner le temps de propagation d'une porte sans simulation. On definit d'autre part une bibliotheque de motifs et de sous circuits ecl pour le compilateur slice, en vue de la generation automatique de cellules ecl sur matrice prediffusee. Les fichiers de simulation pour la caracterisation electrique sur spice sont egalement generes. Dans un deuxieme temps, on propose et on caracterise une nouvelle famille logique ecl multi-niveaux pouvant empiler jusqu'a dix paires differentielles

Neste trabalho serão apresentados novos métodos baseados na geração e controle de comprimento de onda em lasers aleatórios e lasers de diodo. Na primeira parte do trabalho será demonstrado um laser aleatório com realimentação localizada em filmes em biopolímeros dopado com corante. O filme é constituído por um ácido desoxirribonucleico e cloreto de cetiltrimetilamônio (DNA-CTMA) dopado com DCM. No dispositivo proposto, a realimentação óptica para o laser aleatório é dada por centros de dispersão posicionados aleatoriamente ao longo das bordas da área ativa. Os elementos de dispersão são nanopartículas de dióxido de titânio (TiO2) ou defeitos aleatórios na interface entre o polímero ativo e ar. Diferentes espectros de emissão são observados, dependendo da geometria da área excitada. Um único ressonador aleatório com dimensões de 2.6 x 0.65 mm2 foi fabricado com emissão aleatória com realimentação obtida pela excitação do dispositivo por completo. A segunda parte deste trabalho apresenta um novo método para a geração e manipulação de franjas de contorno por meio de interferometria speckle com comprimento de onda sintética, usando um único laser de diodo com cavidade externa. A cavidade externa permite sintonizar duas emissões simultaneamente, o que por sua vez muda o intervalo entre as franjas de contorno do interferômetro, além de aumentar a estabilidade do laser. Uma análise de Fourier é proposta como alternativa para medir o comprimento de onda sintético resultante das duas emissões do laser.In this work, a new method is presented based on generating and controlling the wavelengths emitted by diode lasers and random lasers. In the first part of this work, resonant feedback random lasing from dye-doped biopolymer films is reported, consisting of a deoxyribonucleic acid and cetyltrimethylammonium (DNA-CTMA) complex doped with DCM dye. In the device, the optical feedback for random lasing is given by scattering centers randomly positioned along the edges of the active area. Scattering elements are either titanium dioxide nanoparticles or random defects at the interface between active polymer and air. Different emission spectra are observed, depending on the geometry of the excited area. A single random resonator with dimensions of 2.6 mm x 0.65 mm is fabricated and random emission with resonant feedback is obtained by uniformly pumping the full device. The second part of this work presents a new method for generating and manipulating contour fringes produced with a single external cavity diode laser in a multi-wavelength speckle interferometer. The external cavity allows tuning two simultaneous emissions, which in turn changes the contour interval of interference fringes and also improves laser stability. A Fourier analysis is applied as an alternative method for acquiring the resulting synthetic wavelength from both emissions.

Full textAbstract:
An investigation in to a novel pivot point free external cavity tunable laser (PPI ECTL). Existing external cavity tunable lasers are constructed using tunable optics, such as Bragg gratings to manipulate the cavity length. These elements although functional provide instability with prolonged use as they are defined by a centre of rotation or pivot point. The aim of this research was to provide a lab demonstrator of a new concept tunable laser based on conventional designs. The novel approach to the system design was in the removal of a defined pivot point, whilst still maintaining a moving optical component. The demonstration system will investigate the improvements upon traditional methods of tuning whilst providing greater tuning range and stability. The main defect of conventional systems was the reliance on the defined pivot point of the movable optics. By changing the position of the pivot point, the cavity length will change and the laser mode will change or hop to a side mode. This was known as a mode hop. The objective of the research was to design and implement a durable ECTL with a large tuning range (>200GHz), mode hop free tuning, fibre coupled, circular output beam and a wavelength in the visible. Design and production of a prototype PPI ECT laser that demonstrate the process of mode hop free tuning without the need of a defined pivot point. The impact of the research may lead in to the integration in to lower cost and more reliable commercial applications.

Electron Cyclotron Resonance Heating (ECRH) will be one of the major heating and current drive mechanisms for the ITER fusion experiment. A pair of reflection grating polarizers will be used in the ECRH high power microwave transmission lines to generate the required elliptically polarized microwave beam for ideal plasma coupling. A 'polarization rotator' and a 'circular polarizer' are used together to convert a linearly polarized beam, generated by a gyrotron, to an arbitrary elliptically polarized beam. This thesis presents numerical and experimental results characterizing the elliptical properties of microwaves reflected from a pair of polarizer gratings designed for operation at 170 GHz. First, a theoretical basis is presented for understanding the polarizing behavior of a reflection grating with an arbitrary groove shape. Vector transformations between incident and reflected fields calculated in High Frequency Structural Simulator (HFSS) are used to find the phase shift between the field components that reflect from the top and bottom grating surfaces. Using these results, we characterize the reflecting field by its ellipticity (#) and the angle of rotation of the main polarization axis (a). Next, detailed experimental measurements of the fields reflected from the aforementioned polarizer pair were taken with a Vector Network Analyzer. Very good agreement was seen between the numerical and experimental results and, to our knowledge, these are the first measurements of a polarizer/rotator pair in corrugated waveguide to be successfully compared with theory. Based on these results, we also calculated full polarization maps for grating pairs with alternative groove profiles. We also experimentally studied the mode conversion introduced by the polarization rotator as the grating is rotated about its axis. The presence of higher order modes will increase the ohmic losses along the transmission line.

In 1998 Senegal passed laws that transferred authority over the management of forests to local communities. This dissertation studies the impact of this decentralization on the health of the Samba Dia and Sambande forests and the livelihoods of forest-dependent populations. I use this analysis to reflect on the broader question of the impact of decentralization on conservation and poverty alleviation. I employ temporal and spatial modes of comparison in this study with qualitative research methods. Decentalization has contained forest degradation in both areas. But while people in Samband? forest report benefits to all from the forest, in Keur Samba Dia members of one village report benefits while others decry a reduction in their benefits from the forest. I argue that the transfer of authority from a largely absent and incapable state to well-organized and knowledgeable local communities account for the containment of environmental degradation in both forests. But while the uniform use of the forest by community members has helped people in Samband? solve distributive conflicts and so universally benefit from the forest, a significant divergence in how the two villages in Keur Samba Dia exploit the forest has worsened distributive conflicts allowing the more powerful people of Yayem to benefit more but exclude the less powerful people of Samba Diallo from these new benefits. The impact of decentralization on poverty alleviation and forest health is mediated by important local factors and we should not expect it to have good effects in all areas in which it is pursued.
A descentraliza??o florestal no Senegal constitui o tema desta pesquisa. Em 1998, o Senegal promoveu novas leis florestais que transferiam as compet?ncias de gest?o das florestas para as comunidades rurais, para frear a pobreza e a degrada??o ambiental. Neste contexto, a tese investiga os impactos destas reformas nas vidas das popula??es e nas florestas. A tese tentou lidar com as duas perguntas, se ap?s a descentraliza??o: - as popula??es locais seriam capazes de manejar efetivemente as florestas e o manejo florestal comunit?rio participaria na redu??o da pobreza rural. Fiz um estudo com varia??o espacial e temporal, comparando duas florestas: Keur Samba Dia e Samband? durante dois per?odos diferentes: antes e ap?s a descentraliza??o. Antes de 1998, a gest?o das duas florestas estava sob a responsabilidade do Servi?o Florestal Nacional. Depois de 1998, as comunidades rurais se tornaram as novas autoridades na floresta Samband? enquanto que a floresta Keur Samba Dia permaneceu sob um sistema de co-manejo entre as comunidades rurais e o Estado. A pesquisa deparou com o fato de que, em ambas as florestas, os impactos ecol?gicos da descentraliza??o foram positivos, pois houve uma regenera??o florestal. Todavia, os impactos econ?micos resultantes da descentraliza??o, foram diferentes de uma floresta para outra. Na floresta de Samband?, todos os vilarejos foram beneficiados pela descentraliza??o, enquanto que na floresta de Keur Samba Dia, um vilarejo se sentiu mais prejudicado do que o outro. Estes resultados nos informam, que a participa??o popular foi ben?fica ? sa?de das florestas, mas n?o foi suficiente para que as popula??es se aproveitassem economicamente de uma floresta regenerada. A distribui??o eq?itativa, dos benef?cios econ?micos da descentraliza??o, ? mediada pela uniformidade ou formas conflituosos do uso florestal e por fatores s?cio - hist?ricos.

Length-weight data are the basis of most fish sampling programs and an important tool for fishing biology. Contradictorily, very often research on the relationship between weight and length in fish are disclosed only as brief publications on species for which this information is not yet known. The largest contribution to weight modeling and length was made by Huxley, when a power equation was used to describe the Allometric growth. Although Huxley model has been systematically used in animal growth studies since then, this proposal has limitations in estimating the allometric factor (?b?) as constant throughout the life cycle. Several authors have identified variations in allometric coefficient for animal development, being these complex patterns resulting from various factors and eventually obscured due to natural variability of the data. The objective of this study was to identify growth patterns in fish by using a model that considers changes in the growth occurring during the life cycle and through the crossing of different information of the species biology. We sought to understand the relationships between the polyphasic growth and the achievement of sexual maturity, in the form of migration, with habitat use patterns and the families which belong to the species of study. The data used were obtained from two fronts: (1) review of the database already available in Aquatic Ecology Laboratory of the Catholic University of Rio Grande do Sul (PUCRS) and (2) contact with researchers from other institutions. As a final product, there was obtained a database composed of 78 species divided into 35 families, comprising an array of 92,889 points. The data were imported in the statistical R platform, where an automated algorithm was developed and implemented to adjust the equations. A total of 109 estimates of weight-length were obtained. In general, the average allometric coefficient were slightly larger than 3, for the uniphasic model and for both phases of the polyphasic model, indicating a positive allometry. Multi-modality in the frequency distribution of ! was observed in Huxley's model, this behavior wasn't identified in both phases of polyphasic model. The final adjustment obtained by polyphasic model was satisfactory when evaluated in the context of a large number of species. Strong correlation has been identified between the SCP and (1) the maximum sampled sizes (r2 = 0.94), (2) estimations of first maturity (r2 = 0.93) and (3) length at first maturity (r2 = 0.96). This behavior was also identified between the length at first maturity and estimates of first maturity (r2 = 0.97). The Stanza Changing Points (SCP) were overestimated by approximately 15% when compared with the estimation of first maturity. Estimation of first maturity were overestimated by approximately 5% when crossed with the lengths at first maturity. Patterns were identified in the distribution of homocedastic residuals for species of lotic (p < 0.001) and lentic (p = 0.023) habitats and a significant difference between lotic and neritic environments (p = 0.036). Regarding the form of migration, a pattern was identified in the distribution of error for potamodromous species (p = 0.001) and significant difference between the oceanodromous and potamodromous species (p = 0.023). It wasn?t found any kind of pattern or trend between the SCP and the estimation of first maturity when separated by families. The application of statistical and computational tools developed in this work makes it possible to establish important relationships to improve the understanding of fish growth. Given the ease of obtaining length-weight data, explore this information mathematically can increase understanding of populations of economic and ecological interest, allowing for constantly updating and maintenance information for environmental management and fishing, in addition to stock control.
Dados de peso e comprimento s?o a base da maioria dos programas de amostragens de peixes e uma importante ferramenta em biologia de pesca. Contraditoriamente, com grande frequ?ncia pesquisas sobre a rela??o entre peso e comprimento de peixes s?o divulgadas apenas como breves publica??es sobre esp?cies para as quais esta informa??o ainda n?o ? conhecida. A maior contribui??o para modelagem de peso e comprimento foi feita por Huxley, quando utilizou uma equa??o pot?ncia para descrever o crescimento alom?trico. Embora o modelo de Huxley venha sendo utilizado sistematicamente em estudos de crescimento animal desde ent?o, essa proposta apresenta limita??es por estimar o coeficiente alom?trico (?b?) como constante durante todo ciclo de vida. Diversos autores identificaram varia??es no coeficiente alom?trico durante o desenvolvimento animal, sendo esses padr?es complexos consequentes de diversos fatores e eventualmente obscurecidos devido a variabilidade natural dos dados. O objetivo deste trabalho foi identificar padr?es de crescimento em peixes atrav?s da utiliza??o de um modelo que considere altera??es no crescimento que ocorram durante o ciclo de vida e atrav?s do cruzamento de diferentes informa??es sobre a biologia das esp?cies. Buscou-se o entendimento de rela??es entre o crescimento polif?sico e o atingimento da maturidade sexual, com a forma de migra??o, com os padr?es de ocupa??o de h?bitat e com as fam?lias as quais pertencem as esp?cies de estudo. Os dados utilizados foram obtidos atrav?s de duas frentes: (1) revis?o do banco de dados j? dispon?vel no Laborat?rio de Ecologia Aqu?tica da Pontif?cia Universidade Cat?lica do Rio Grande do Sul (PUCRS) e (2) contato com pesquisadores de outras institui??es. Como produto final, obteve-se um banco de dados composto por 78 esp?cies divididas em 35 fam?lias, compondo uma matriz de 92.889 pontos. Os dados foram trabalhados sobre a plataforma estat?stica R, onde foi desenvolvido e aplicado um algoritmo automatizado para ajuste das equa??es. No total, 109 estimativas de peso-comprimento foram realizadas. De forma geral, as m?dias do coeficiente alom?trico foram ligeiramente maiores que 3, tanto para o modelo unif?sico de Huxley como para ambas as fases do modelo polif?sico, indicando alometria positiva. Foi poss?vel observar multi-modalidade na distribui??o de frequ?ncia de ! no modelo de Huxley, comportamento n?o identificado nas duas fases do modelo polif?sico. Foi identificada forte correla??o entre os Pontos de Mudan?a de Fase (SCP) e (1) os tamanhos m?ximos amostrados (r2 = 0,94), (2) estimativas de primeira matura??o (r2 = 0,93) e (3) comprimento de primeira matura??o (r2 = 0,96). Esse comportamento tamb?m foi identificado entre o comprimento de primeira matura??o e as estimativas de primeira matura??o (r2 = 0,97). Os pontos de mudan?a de fase foram superestimados em aproximadamente 15% quando comparados com as estimativas de primeira matura??o. As estimativas de primeira matura??o foram superestimadas em aproximadamente 5% quando cruzadas com os comprimentos de primeira matura??o. Foram identificados padr?es na distribui??o dos res?duos homoced?sticos para as esp?cies de ambientes l?ticos (p < 0,001) e l?nticos (p = 0,023) e diferen?a significativa no cruzamento entre os ambientes l?tico e ner?tico (p = 0,036). Com rela??o a forma de migra??o, foi identificado padr?o na distribui??o dos erro para as esp?cies potam?dromas (p < 0,001) e diferen?a significativa entre as esp?cies ocean?dromas e potam?dromas (p = 0,023). N?o foi encontrado qualquer tipo de padr?o ou tend?ncia entre os SCP e as estimativas de primeira matura??o quando separados por fam?lias. A aplica??o das ferramentas estat?sticas e computacionais desenvolvidas nesse trabalho torna poss?vel estabelecer importantes rela??es para melhorar o entendimento sobre o crescimento de peixes. Tendo em vista a facilidade de obten??o de dados de peso-comprimento, explorar matematicamente essas informa??es pode aumentar o entendimento das popula??es de interesse econ?mico e ecol?gico, permitindo uma constante atualiza??o e manuten??o de informa??es de gest?o ambiental e de pesca, al?m do controle de estoque.

This research integrate the line of research named ?Theories and Cultures in Education?, of the Graduate Program in Education of the Pontif?cia Universidade Cat?lica of Rio Grande do Sul - PUCRS. The research problem/question aims to understand how ecological practices are related to innovation in education, in a general way and, specifically, in the schools of the "Map of Innovation and Creativity in Basic Education" from the Ministry of Education (BRASIL, 2015) in S?o Paulo/SP. The specific questions are: how does this public policy understand innovation in education; what are the perspectives of the schools selected for the Map regarding their practices; how does the innovative character point to the position of "environmental" indicators such as sustainability and ecology. The general objective is to investigate how the relationships between educational innovation and ecological practices are experienced in the schools of the Map of Innovation and Creativity in Basic Education in the city of S?o Paulo/SP. The specific objectives of the research are: a) to describe how the conception of innovation is transposed from the corporate field to that of education; b) analyze the criteria used by the Evaluation Committee of the MEC for the selection of innovative and creative schools; c) to observe the perspectives of the selected schools on their innovations and how they articulate them in their daily life; d) identify the presence/ absence of an environmental approach in these institutions, describing their particularities. The theoretical framework dialogues with the concepts of innovation and education as they emerge in the literature, but, mainly, how they are received and re-signified from the empirical field. The methodology used includes documentary analysis and participant observation. As ethical care, it was used a letter of presentation directed to the school and verbal consent of the people contacted, obtained by telephone. The identity of schools and interlocutors has been preserved. Results: it was possible to identify different relationships between education, innovation and ecology in the schools studied. From the recurrent themes that emerged from empirical research, nine categories of analysis were generated. Of these categories, a new division into three major groups proposes an integrated view of schools and their interactions with the central themes of the research.
O presente trabalho est? inserido na Linha de Pesquisa Teorias e Culturas em Educa??o, do Programa de P?s-gradua??o em Educa??o da Pontif?cia Universidade Cat?lica do Rio Grande do Sul - PUCRS. O problema de pesquisa pretendeu compreender de que forma as pr?ticas ecol?gicas est?o relacionadas ? inova??o no campo da educa??o, de um modo geral e, em particular, nas Escolas pertencentes ao ?Mapa de Inova??o e Criatividade na Educa??o B?sica? (BRASIL, 2015) em S?o Paulo/SP. As perguntas espec?ficas s?o: de que forma essa pol?tica p?blica entende inova??o na educa??o; quais as perspectivas das escolas selecionadas para o Mapa a respeito de suas pr?ticas; como o car?ter inovador aponta para a posi??o dos indexadores ?ambientais? como a sustentabilidade e a ecologia. Objetivo geral: investigar como as rela??es entre inova??o educacional e pr?ticas ecol?gicas s?o experienciadas nas escolas pertencentes ao Mapa da Inova??o e Criatividade na Educa??o B?sica do Minist?rio da Educa??o localizadas. Os objetivos espec?ficos s?o: a) descrever como a concep??o de inova??o ? transposta do campo corporativo para o da educa??o; b) analisar os crit?rios utilizados pela Comiss?o Avaliadora do MEC para a sele??o das escolas inovadoras e criativas; c) observar as perspectivas das escolas selecionadas sobre suas inova??es e como as articulam em seu cotidiano; d) identificar a presen?a/aus?ncia de uma abordagem ambiental nessas institui??es, descrevendo suas particularidades. O marco te?rico dialoga com os conceitos de inova??o, educa??o e perspectivas ecol?gicas tal como emergem na literatura, mas, sobretudo, como s?o recebidos e ressignificados desde o campo emp?rico. A metodologia utilizada incluiu an?lise documental e observa??o participante. Como cuidados ?ticos foi utilizada carta de apresenta??o da pesquisa dirigida ? escola e consentimentos verbais das pessoas contatadas, obtidos por telefone. A identidade das escolas e dos interlocutores foi preservada. Resultados: foi poss?vel identificar diferentes rela??es entre educa??o, inova??o e ecologia nas escolas estudadas. A partir dos temas recorrentes que emergiram da pesquisa emp?rica, foram geradas nove categorias de an?lise. Dessas categorias, uma nova divis?o em tr?s grandes grupos prop?e uma vis?o integrada a respeito das escolas e suas intera??es com os temas centrais da pesquisa.

Previous issue date: 2010-08-30Many environmental ethics thinkers bear the existing ecological crisis is resultig from the fact that both, our thoughts and our actions would be antropocentric. It means that they (our thoughts and our actions) would have the human needs and wishes satisfaction as their only goals. However, a careful investigation about the relationship among humans could perhaps unveil that we are not antropocentric yet. The aim of this work is to enlighten this: whether we think and act in an antropocentric way as it seems to be largely accepted. It seems that we have found a satisfatory answer to the question
Grande parte dos pensadores da ?tica ambiental credita a crise ecol?gica da atualidade ao fato de que tanto o pensamento quanto as a??es dos seres humanos seriam antropoc?ntricos, ou seja, teriam como objetivo ?nico a satisfa??o de necessidades e desejos dos pr?prios homens. No entanto, uma cuidadosa investiga??o sobre a rela??o que os humanos mant?m entre si poderia revelar que talvez n?o sejamos verdadeiramente nem sequer antropoc?ntricos. O objetivo deste trabalho ? tentar trazer ? luz mais conhecimentos sobre isto: se de fato pensamos e agimos de forma antropoc?ntrica, como ? amplamente aceito. E parece que conseguimos nos aproximar de uma resposta satisfat?ria para a quest?o
