L’étude de la protection sociale de l’agriculteur victime d’accidents fait le constatd’inégalités manifestes entre les victimes elles-mêmes et entre le régime des accidents dutravail et celui du droit commun. Ces inégalités sont inhérentes à la qualité d’agriculteur ;qu’il soit salarié ou non, ce dernier ne bénéficie pas des mêmes droits. En outre, l’agriculteurblessé dans le cadre de son activité professionnelle n’aura qu’une réparation forfaitaire. Cettedernière tend à compenser la perte de revenu et l’incidence professionnelle de l’accident.L’indemnisation des préjudices personnels est exclue, sauf dans l’hypothèse d’une fauteinexcusable de l’employeur. Quant aux victimes d’accidents de droit commun, leur protectionsociale n’est optimisée que si elles possèdent une complémentaire prévoyance qui va parfaireles remboursements en espèces et en nature du régime agricole. En dehors de la prise encharge du régime légal de base, la réparation des accidents de droit commun tend à êtreintégrale. Afin que toutes les victimes d’accidents soient traitées de manière égale par le droitet qu’une réparation de tous leurs préjudices puisse être réalisée, nous préconisons dessolutions pour tenter de faire disparaître les inégalités entre les agriculteurs victimesd’accidents. / The study of the social welfare of the farmer victim of accidents reveals theexistence of disparities between the victims themselves and between the industrial accidentsand the common law. These disparities are inherent to farmer’s quality; whether he isemployed or not, the latter does not benefit from the same rights. In addition, the injuredfarmer in the course of his professional activity will have only a fixed compensation. Thelatter tends to compensate the loss of income and the professional incidence of the accident.Compensation for personal injury is excluded except in the hypothesis of unforgivablemisconduct of the employer. As for the victims of accidents of common law, their socialwelfare is only optimized if they possess a top up insurance plan that will completerepayments in cash and in kind of the agricultural system. Except the coverage of the basiclegal system, the compensation of accidents of common law tends to be complete. In order toensure that all accident victims are treated with equal manner by law and that compensationfor all their injuries can be achieved, we recommend solutions so that the disparities betweenthe farmers victims of accidents can disappear.

Researchers conceptually recommend inquiry-based learning as a necessary means to alleviate the problems of learning but this study has embarked on practical implementation of inquiry-based facilitation and learning in Euclidean Geometry. Inquiry-based learning is student-centred. Therefore, the teaching or monitoring of inquiry-based learning in this study is referred to as inquiry-based facilitation. The null hypothesis discarded in this study explains that there is no difference between inquiry-based facilitation and traditional axiomatic approach in teaching Euclidean Geometry, that is, H0: μinquiry-based facilitation = μtraditional axiomatic approach. This study emphasises a pragmatist view that constructivism is fundamental to realism, that is, inductive inquiry supplements deductive inquiry in teaching and learning. Participants in this study comprise schools in Tshwane North district that served as experimental group and Tshwane West district schools classified as comparison group. The two districts are in the Gauteng Province of South Africa. The total number of students who participated is 166, that is, 97 students in the experimental group and 69 students in the comparison group. Convenient sampling applied and three experimental and three comparison group schools were sampled. Embedded mixed-method methodology was employed. Quantitative and qualitative methodologies are integrated in collecting data; analysis and interpretation of data. Inquiry-based-facilitation occurred in experimental group when the facilitator probed asking students to research, weigh evidence, explore, share discoveries, allow students to display authentic knowledge and skills and guiding students to apply knowledge and skills to solve problems for the classroom and for the world out of the classroom. In response to inquiry-based facilitation, students engaged in cooperative learning, exploration, self-centred and self-regulated learning in order to acquire knowledge and skills. In the comparison group, teaching progressed as usual. Quantitative data revealed that on average, participant that received intervention through inquiry-based facilitation acquired inquiry-based learning skills and improved (M= -7.773, SE= 0.7146) than those who did not receive intervention (M= -0.221, SE = 0.4429). This difference (-7.547), 95% CI (-8.08, 5.69), was significant at t (10.88), p = 0.0001, p<0.05 and represented a large effect size of 0.55. The large effect size emphasises that inquiry-based facilitation contributed significantly towards improvement in inquiry-based learning and that the framework contributed by this study can be considered as a framework of inquiry-based facilitation in Euclidean Geometry. This study has shown that the traditional axiomatic approach promotes rote learning; passive, deductive and algorithmic learning that obstructs application of knowledge in problem-solving. Therefore, this study asserts that the application of Inquiry-based facilitation to implement inquiry-based learning promotes deeper, authentic, non-algorithmic, self-regulated learning that enhances problem-solving skills in Euclidean Geometry. / Mathematics Education / Ph.

Zusammenfassung Die vorliegende Forschungsarbeit unternimmt den Versuch, einen konzeptionellen Entwurf einer empirischen Missionswissenschaft als Grundlagenforschung zu entwickeln, der im Praxisfeld durchgeführt wird. Dabei soll die intradisziplinäre Vorgehensweise einen methodologischen Zugang sozialwissenschaftlicher Methoden zur Missionswissenschaft möglich machen. Als Grundlage wird ein Einblick in die sozialwissenschaftliche und missionswissenschaftliche Forschung gegeben und daraus ein eigener, empirisch-theologischer Praxiszyklus entwickelt, der die Methodologie der Untersuchung darstellt. Die inhaltliche Forschungsarbeit fragt nach Gottesvorstellungen von Jugendlichen aus missionswissenschaftlicher Sicht. Dabei wird die Möglichkeit missionarischer Begegnung und Ansprechbarkeit von Jugendlichen im Kontext der kulturellen Veränderungen des postmodernen Paradigmemwechsels beleuchtet. Die Frage, wie Gottesvorstellungen von Jugendlichen gesellschaftlich geprägt und wie sich dies auf ihre Religiosität in ihrem Alltag auswirkt, spielt in diesem Zusammenhang eine wichtige Rolle. Deshalb wird nicht nur der aktuelle Forschungsstand zur Thematik untersucht, sondern 18 Jugendliche werden in Form von halbstandardisierten Interviews qualitativ befragt und ihre Aussagen empirisch-missiologisch ausgewertet. Die Thesis hat somit zweierlei Zielsetzungen: Zum einen geht es um eine empirisch-theologische Studie zur Erforschung von Gottesvorstellung bei Jugendlichen im Hinblick auf ihre missionarische Ansprechbarkeit. Zum anderen zielt sie darauf ab, durch Umsetzung des empirisch-theologischen Praxiszyklus einen Typus zu entwickeln, der auch künftig in der Missionswissenschaft für empirisch-theologische Erhebungen eingesetzt werden kann. Summary The intention of this research project is to evolve a concept for empirical missiology as a method of fundamental research and to apply it in practice. Through the usage of an intradisciplinary approach, access to missiology via the methodology of the social sciences is rendered possible. To establish a basis, an insight into social as well as missiological research will be given, and an inherent, empirical-theological praxis cycle will be developed. This praxis cycle is the methodology of this research paper. Concerning content, this research paper scrutinises the image of God held by juveniles from a missiological point of view. It considers the missionary receptiveness of juveniles in the context of cultural change in the postmodernist shift of paradigm. In how far are juvenile concepts of God marked by the correspondent social environment and does that have an impact on their everyday religious behaviour? Consequently not only the current state of research will be evaluated but, furthermore, the half-standardised qualitative interviews of 18 juveniles will be enclosed and their answers analysed on an empirical- missiological basis. Hence, this thesis has a twofold aim; one considers empirical-theological research as a way of evaluating concepts of God among juveniles with regard to their missionary receptiveness. The other implements the empirical-theological praxis cycle aiming to develop a type which enables further empirical-theological investigation in missilogy. / Missiology / D.Th.

所有權結構、支付制度與競爭係影響醫院績效之關鍵因子，本研究援用相關文獻之發現，推論出三項因素對醫院績效之關係，並以我國獨特之總額預算制度為研究對象，蒐集、串連與合併不同來源之資料，實證檢視衝量競爭與所有權結構對醫院營運績效與醫療品質之聯合效果。 台灣於民國91年7月實施醫院總額預算制度後，浮動點值制度之設計為醫院間引入了衝量競爭(即虛假價格競爭)，而結算後之點值則係反映出醫院間衝量競爭後之結果，醫院除了需面對支付點值所致之財務衝擊外，尚須面對自全民健保實行後，備受醫院詬病之核減制度之衝擊，因此，本文首先嘗試估算醫院受到核減與支付點值所致之財務衝擊程度。無論是國外或國內之研究，對於不同所有權結構醫院之績效表現是否有差異性，一直無法獲得一致性之結論，除了納入營運效率之績效指標外，本研究亦採用疾病別與醫院層級別之醫療品質指標來檢視不同所有權結構醫院之績效表現。更以考量核減與支付點值所致之財務衝擊程度，取代目前文獻僅以總額前、後之二元變數，評估財務衝擊程度對營運效率、醫療品質與財務績效之影響。最後，則是檢視總額預算制度下，醫院受到之財務衝擊度是否會縮小不同所有權結構醫院之營運效率與醫療品質表現之差距。 實證研究發現，不同所有權結構醫院之營運效率並未有顯著差異，但不同所有權結構醫院在某些疾病別品質指標(子宮肌瘤切除手術之住院超過7日機率與再入院率)與醫院層級品質指標(院內感染率與淨死亡率)表現上則有差異性；且公立或非營利醫院受到核減與支付點值之財務衝擊高於私立醫院，因此不同所有權結構醫院之行為與績效存有某些差異性。台灣的醫院在總額預算制度下，若受到之財務衝擊程度愈大，其營運效率會變差、醫療品質也受到負面之影響、財團法人醫院之醫務利益率與稅後淨利率也會降低，但現金流量比則會增加，故財務衝擊愈大，醫院之績效愈低。若同時考量財務衝擊度對不同所有權結構醫院之營運效率與醫療品質之聯合效果後，可發現財務衝擊雖然不會縮小公立(或非營利)醫院與私立醫院營運效率之差距，卻縮小公立(或非營利)醫院與私立醫院醫療品質之差距，故以台灣資料可部分支持「不同所有權結構醫院績效差距縮小之因素係競爭力量之崛起」之論點。 / Hospital ownership, payment system and competition are all key drivers to influence hospital performance. This research infer and depict the association of these three drivers from the related literature and empirically examined the effects of fictitious price competition due to the floating point-value system and ownership on hospital operational performance and quality of care by combing and merging different sources of data. Deduction rate of claim and the floating point-value system are the two controversial debates to the payment system. I attempt to estimate hospital financial pressures as precipitated by deduction rate of claim and floating point-value system. To investigate whether for-profit, not-for-profit, and government hospitals differ in operating performance and quality of care, five diagnose-level and two hospital-level quality indicators are selected. Different from prior research, the financial pressure is captured by hospital data instead of a binary variable (pre and post global budget) and I examine the effect of financial pressure on hospital operational efficiency, quality of care and financial performance. Finally, we test whether differences in operational efficiency and quality care among hospitals with different ownership forms will mitigate or narrow, as hospital financial pressure increases. The results show that for-profit, not-for-profit and government hospitals are far more alike than different in operational efficiency, but ownership affects not only the rate of readmission and the rate of the length of stay larger than 7 days of uterine myomectomy, but also the hospital-level quality indicators: the rate of nosocomial infection and hospital mortality rate. I also find higher financial pressure incurred at government or not-for-profit hospitals than for-profits hospitals. Given my findings, we conclude that hospital ownership status affect performance in terms of quality of care and financial pressure from rate of deduction and float point-value system. The study shows that financial pressure adversely affects operational efficiency and quality of care. As not-for proprietary hospital financial pressure increases, the profit margin and net profit ratio will decrease, but the cash flow ratio will increase. Nonetheless, deduction rate of claim and global budget has a negative impact on hospital performance. This research further considers the joint effect of financial pressure on difference between quality of care and efficiency of for-profit hospitals and the other two types. My results indicate that hospital financial pressure mitigates the difference of quality of care between for-profit hospital and not-for profit (or government) hospitals, but does not narrow the difference in quality of care between for-profit hospital and not-for profit (or government) hospitals. This finding partly supports that increased competition should force not-for-profit (or governmental) hospitals to be increasingly similar to their for-profit counterparts.

論文摘要 〈論純粹知性概念之推證〉一章可以說是《純粹理性批判》當中最重要的章節之一。康德在這個章節中企圖證明完全根源於知性自身的純粹知性概念（也就是範疇）運用到經驗對象上的可能性，並藉此劃定認知的有效範圍。這是《純粹理性批判》企圖解決形上學紛爭的一個重要關鍵。然而，這個章節同時也是康德宣稱他花費了最大心力，並在第二版《純粹理性批判》當中完全改寫的篇章之一，在這個短短的五六十頁的篇幅當中卻包含了許多詮釋上的爭議。而本論文則以第二版〈推證〉為主要討論範圍，並嘗試回答其中三個詮釋上的問題：1. 〈推證〉是否包含了一個反懷疑論的論證？2. 第二版〈推證〉可區分出的兩個部份分別負擔了什麼任務？3. 先驗統覺在〈推證〉中扮演了什麼角色？並在確立對以上幾個問題的觀點之後，提供一個的對第二版〈推證〉的細部解釋。 為了回答這幾個問題，筆者比較了Paul Guyer、Dieter Henrich、Henry Allison等幾個詮釋者的觀點。而本論文總共包含了五個章節。第一章作為導論，介紹筆者在本論文中所欲處理的問題以及對論文所安排的架構。在第二章當中，筆者以Guyer作為一個反懷疑論式詮釋〈推證〉的類型，並指出這種詮釋方式與文本的不合之處。在第三章當中，筆者將介紹Henrich針對第二版〈推證〉所提出的「一個證明兩個步驟」的詮釋架構以及對兩個步驟的詮釋，並藉由Allison的批評，介紹另一種同樣在「一個證明兩個步驟」下且筆者認為更適當的詮釋方式。在第四章當中，筆者嘗試回答關於解釋統覺的諸問題，它們包括了統覺的含義、統覺與雜多表象的關係、統覺原理的邏輯地位、統覺原理在〈推證〉中起的作用等。在確立了以上諸觀點後，筆者在第四章和第五章當中，按照兩個步驟的架構提供一個對第二版〈推證〉的完整解釋。 / Abstract "On the Deduction of the Pure Concepts of Understanding" is widely agreed to be the most important chapter in the Critique of the Pure Reason. In this chapter Kant attempts to demonstrate that the pure concepts of understanding, namely, categories, which completely stem from understanding itself, can be applied to empirical objects and thereby define the boundary of cognition. This is critical to resolve the dispute in the metaphysics of his predecessors. However, Kant also claims that this chapter is the part, which costs him the greatest effort and which he entirely rewrites in the second edition of the Critique. There are so many controversial interpretations related to this chapter, which is yet only complied up to 50-60 pages. In this thesis I focus on Deduction in the second edition of the Critique and try to answer the following three questions about these controversies: 1. Whether the Deduction contains an anti-skeptical argument? 2. What are the tasks of the two parts respectively that can be distinguished in B-Deduction? 3. What is the role that transcendental apperception plays in the Deduction? After establishing these answers, I will contribute a detailed explanation of whole B-Deduction. In order to answer the questions, I compare the perspectives of three interpreters of Kant, namely, Paul Guyer, Dieter Henrich and Henry E. Allison. This article is divided into five chapters. Chapter 1 is the introduction, in which I introduce the problems that I hope to resolve and the structure of the thesis. In Chapter 2, I introduce Guyer's interpretation of Deduction, which is an anti-skeptical Model, and I will indicate that his interpretation doesn't conform to the Kant's text. In Chapter 3, I introduce Henrich's famous thesis about the structure of the B-Deduction, namely, the thesis of two-steps-in-one-proof, and his interpretation of the contents of the two steps.Then I introduce Allison's criticism against Henrich and his alternative interpretation of B-Deduction under the frame of two-steps-in-one-proof. I believe this interpretation is more consistent and more conformable to the text. In Chapter 4, I try to answer the questions about the interpretation of apperception, where the issues such as the meaning of apperception, the relation between apperception and manifold, the principle of apperception's logical status, the apperception's role in the Deduction etc. will be discussed. After establishing my perspectives about these interpretative problems, I will present a complete and detailed explanation of B-Deduction according to the two-step structure.

The research has as its starting point the analysis of the constitutional text, seeking to build content, meaning and scope of prescriptive statements that impact directly on the legal regime of the ISS. In this plan, we focus the study of standards of competence of the ISS and what constitutes it and other infraconstitucional enunciations, through studying the role of supplementary law on the conformation of the legal system of the ISS. Traced the boundaries of both substance and form that define the institution of Tax Services at the constitutional level, the archetype of this constitutional duty is achieved, partly to investigate these prescriptive statements introduced in the legal system from the LC 116/03, analyzing the limits of positive law, each of the criteria of the rule of taxation possible from the ISS by building their semantic content, focusing on those that can trigger further discussions in relation to the tax in imports of services, namely the substantive test, the space and subjective criteria. We concluded that neither the constitutional legislator nor complement legislator, the determination of the substantive (conjugation of the verb with the complement), limited, both vehicles sheaths to address the possible materiality of the tax as the provision of services. On the space criterion, closely related to the principle of territoriality, we verify the possibility of adopting the principle of origin, as well as the destination on the taxation of services, being indispensable to the location of taxable activity the existence of evidence of connection to the Brazilian legal system, in order to legitimize the tax. Regarding the subjective criterion, especially on the topic of passive submission, we note that the legislature has the freedom to choose those which are responsible for compliance with the tax liability within the prescribed limits, may choose different person from the one who gets the economic benefit arising from activity of service provision, provided that there is another rule that permits restitution (reimbursement or retention). That done, we begin the analysis of rule of tax incidence of the incident ISS on the import of services covered by the same method in the previous steps, proving its compatibility with the Brazilian legal system / O objetivo do presente trabalho é estudar as normas que dispõem sobre a incidência do Imposto sobre Serviços de Qualquer Natureza nas situações que caracterizam a importação de serviços, a fim de verificar a sua compatibilidade com o ordenamento jurídico-positivo. A pesquisa tem como ponto de partida a análise do Texto Constitucional, buscando construir o conteúdo, sentido e alcance dos enunciados prescritivos que influem diretamente no regime jurídico do ISS. Neste plano, as atenções se voltam para o estudo da norma de competência do ISS e dos seus integrantes constitutivos como os princípios e demais enunciados infraconstitucionais, passando pelo estudo do papel da lei complementar na conformação do regime jurídico do ISS. Traçados os limites de fundo e de forma que delimitam a instituição do Imposto sobre Serviços no plano constitucional, alcança-se o arquétipo constitucional deste imposto, parte para a investigação dos enunciados prescritivos introduzidos no ordenamento jurídico a partir da LC n. 116/03, analisando dentro dos limites do direito positivo, cada um dos critérios integrantes da regra-matriz de incidência tributária possível do ISS, a partir da construção dos respectivos conteúdos semânticos, enfatizando aqueles que podem provocar maiores discussões em relação à incidência do imposto na importação de serviços, a saber o critério material, o critério espacial e o critério subjetivo. Conclui que não houve por parte, seja do legislador constitucional seja do legislador complementar, a determinação do critério material (conjugação do verbo com o complemento), limitando-se, ambos os veículos introdutores, a tratar da materialidade possível do imposto como sendo a prestação de serviços. Quanto ao critério espacial, intimamente relacionado ao princípio da territorialidade, verifica-se a possibilidade de adoção do princípio da origem, tanto quanto do destino na tributação da prestação de serviços, sendo indispensável para a localização da atividade tributável a existência de elementos de conexão com o ordenamento jurídico brasileiro, de modo a legitimar a tributação. Em relação ao critério subjetivo, em especial no tópico da sujeição passiva, constata-se que tem o legislador liberdade para a escolha daquele a quem incumbe o cumprimento da obrigação tributária, dentro dos limites previstos, podendo escolher pessoa diversa daquela que obtém o benefício econômico decorrente da atividade de prestação de serviço, desde que exista uma outra norma, que autorize a restituição (retenção ou reembolso). Feito isso, tem início a análise da regra-matriz de incidência tributária do ISS incidente na importação de serviços, pelo mesmo método percorrido nas etapas anteriores, concluindo pela sua compatibilidade com o ordenamento jurídico brasileiro

Ce document présente l'étude de plusieurs modèles de machines à états finis qui étendent tous le même formalisme: les automates d'arbres classiques, et leur application dans différentes tâches telles que l'analyse statique de programmes ou de systèmes, la typage, la vérification de la cohérence de spécifications, le model checking... Les arbres sont une structure naturelle de données, très répandue en informatique, par exemple pour la représentation des structures de données hiérarchiques ou imbriquées, pour des algorithmes spécifiques (arbres binaires de recherche, algorithmes distribués), comme modèle abstrait pour des données semi-structurées utilisées pour l'échange d'information dans le Web, pour une présentation algébrique de processus récursifs, comme les termes en logique... Lorsqu'il s'agit de raisonner sur des systèmes manipulant des arbres, ou modelisés par des arbres, il est crucial d'avoir une représentation finie d'ensembles infinis d'arbres. Les automates d'arbres sont des machines à états finis permettant une telle représentation. Ils ont fait la preuve de leur adéquation à des tâches de raisonnement: ils ont un modèle théorique bien établi, en étroite relation avec la logique, ils bénéficient de bonnes propriétés de composition et d'algorithmes de décision efficaces. En particulier, les automates d'arbres sont utilisées au coeur de systèmes de vérification formelle d'outils de déduction automatique. Toutefois, les automates d'arbres ont des limitations sévères en expressivité. Par exemple, ils sont incapables de faire du filtrage non-linéaire ou d'exprimer des contraintes d'intégrité tels que les clés dans les bases de données. Certaines extensions ont été proposées afin d'améliorer le modèle en essayant de conserver de bonnes propriétés. Nous présentons dans ce document de plusieurs de telles extensions, leurs propriétés et leur utilisation en vérification symbolique de systèmes et de programmes.

The aim of the thesis is to examine both Husserl's and Kant's transcendentalism in a way that would avoid the tendency to put the main accent on Husserl, which is an approach common to almost all literature dealing with this topic so far. Since it is for the most part Husserl's own critique of Kant that inspires such ongoing underestimation of Kant in comparison to Husserl, this work focuss on the question of the legitimacy of this critique. The core of the thesis is an original interpretation of Kant's transcendental philosophy which, instead of taking for granted the phenomenological point of view, attempts to describe Kant's philosophical enterprise from its own perspective and in its own right. In its second part, the thesis provides a brief description of how Husserl, starting initially from the position of descriptive psychology, arrives at a transcendental dimension. When so put side by side, it becomes evident that the two transcendental positions are in fact very different. Husserl's critique of Kant then appears as unjustified, even though quite understandable as an attempt to draw back from certain immature motives of his own philosophy.
