Full textThis thesis follows a chronological study of the evolution of the mythical image of the raven in European literature. In the first part it describes the sacred and divine origins of the raven in simple tales and written myths and presents the raven as both divinity and a companion of divinities. The passage from myth, to superstition and magic, transforms its image as sacred raven into that of diabolical raven. The influence of the Judeo-Christian complex completes this negative image, which began as both good and evil. In tales, legends, and fables, the biblical image merges with the mythic corpus. In the second part, we see that in 19th and 20th century literature its role changes from that of an acting personality to a sign or a symbol. H. Heine, W. Muller, E. Allen Poe and F. Nietzsche use the raven as the symbol of all the ills of the century during the romantic period. It is the symbol of war and interior and exterior upheaval in A. Rimbaud, G. Trakl, J. Giono, J-P. Sartre and I. Calvino. Its symbolism is again double as in mythology - at once destroyer and creator. For F. Zorn, the raven is the symbol of death and deliverance. In the third part we see that the corruption of the image of the raven as an active personality and as a symbol is thrown into question. With irony and exaggeration, W. Busch and C. Morgenstern present ravens that are grotesque caricatures of the sacred and diabolic bird. The importance of the image of the raven in European civilization is confirmed in painting. It symbolizes, as in literature, external trouble and strife and the interior psychology of the artist. The image of the raven in literature is an example of the constant exchanges between different civilizations, of communication between people and embodies their common aspirations

Full textWith the increase of life expectancy, psychological writings about ageing have not developed as much as those concerning adults and children. It seemed to us interesting, fascinating and fruitful to think about this senescence period by restating the « somat/psyche » duality throughout the deterioration event. The use of a quantitative and qualitative methodology allows us to tackle the fall event as a traumatic experience according to physical data (fragile ou valid subject, somatic or psychomotor consequences…), temporal (since the last fall, moment of the fall, objective and subjective age of the fall…) and psychic (defenses set up, reminiscence, the work of getting old…) So we specifically looked at the turning point of this event in the context of expensive treatment of conflicts emerging at that time to discover obsessive defense mechanisms and primary maternal regression. In consequence, the development of psychological and psychoanalytical reasoning on the observation of the fall of the ageing subject can only be appreciated by not « falling » in the belief of a unique link of casuality, within an indistinguishable demographic class where age would be seen as an etiological factor. The use of quantitative and qualitative analysis of the discourse gives access to postfall reactive data but also to psychic treatment methods of the conflicts and affects which emerged from this event. We combined verbal communication with the drawing technique to get an insight of the mental images set in the historical narrative of memory. The fall is then exposed as an action, to mitigate the failure of the protective shield system and the capacities of development and connection to the narcissistic injury of senescence. However, it can also be appreciated as a coming back an elaborative resumption of attachment that leads to an inevitable end. It was then that "what is called a reason for living is also an excellent reason for dying" (Albert Camus). Indeed writings on the subject of the psychological deterioration of the ageing person are mainly studied in the context of the psychopathological or deficient process of the frail person in question, hospitalized without really taking into account the individual and collective complex alterations common to the process of ageing. We therefore concentrated on the psychic process of a valid old subject in order to glean more clinical reflections on the type of anxiety and object interaction. The TAT/SAT proposed concerning our study has established the psychic constitution of an internal model of an insecure relationship of the ageing, linked with an infringing relational experience with a failing and disappointing maternal object

Full textLike other arts, the movies, under Vichy, did not escape to diverse measures of restriction that regulate its production, its distribution and its exploitation. In order to divert the attention of German and Vichyssoises authorities, many producers of this period expressed their ideas through poetic, pseudohistorical and fantastic themes. Among these is Henri-Georges Clouzot, who, in his work "The raven", knew how to make of a commonplace news item a pessimistic feeling of a whole country. Considered as the flashing movie of the occupation, "The raven" deals particularly with the individual's psychology, and evokes a general atmosphere of hatred, denunciation and jealousy

Full textNowadays, fall detection is a major challenge in the public health care domain, especially for the elderly living alone and rehabilitants in hospitals. This thesis presents an exploration for a Fall Detection System based on camera under an algorithmic and architectural point of view. Our system includes four modules: Object Segmentation, Filter, Feature Extraction and Recognition and give an urgent alarm for detecting different kinds of fall. Firstly, different algorithms for the Fall Detection System are proposed and compared the efficiency among Background Subtraction-Neural Network, Background Subtraction-Template Matching (BGS/TM), Background Subtraction-Hidden Markov Model, and Gaussian Mixture Model. Therefore, the selected BGS/TM with 91.67% (Recall), 100% (Precision) and 95.65% (Accuracy) will be implemented on ZYNQ platform. Moreover, a DUT-HBU database which is classified with different actions: fall, non-fall in three camera directions is used to evaluate the efficiency of this system. Secondly, the aim is to explore low cost architectures for this system, new power consumption and execution time models for processor core and FPGA are defined according to the different configurations of architecture and applications. The error rates of the proposed models don’t exceed 3.5%. The models are then extended to hardware/software architectures to explore low cost architecture by defining a suitable Design Space Exploration methodology. Two techniques for parallelization which are based on intra-task and inter-task static scheduling are applied with the aim to enhance the accuracy and the power consumption of this system reaches 98.3% with energy per frame of 29.5mJ/f

Full textFor Bernstein (1967), the solution to the problem of degrees of freedom (DF) would be to freeze and reduce the number of DF to be controlled. With the practice effect, DFs would be gradually thawed and more exploited. Studies have shown that both strategy the freezing/thawing and the thawing/freezing of DF can be used at the beginning of the learning process and that the strategy to be explored depends on the skill and its purpose. However, there is no evidence that demonstrates in which classes of skill and its purpose these strategies would be use. The objective of this study was to analyze the effect of the practice in the coordination and the reorganization of the DF during the learning of a discrete skill with speed and accuracy of the movement as its purpose (Taekwondo back kick). Thirteen participants with a mean age of 20 years formed the group of inexperienced (GI). They performed 18 practice sessions, totaling 720 repetitions of the kick, and were evaluated by means of cinemetry (pre-test, post-test and retention). Eleven Taekwondo athletes with a mean age of 21 years formed the group of experienced (GE) that was used as a parameter to evaluate the changes in the GI?s kick. Contrary to Bernstein's hypothesis, GI froze DFs throughout learning, reducing knee joint range of motion. Moderate and strong correlations between the adjacent joints demonstrated that the in phase inter joints coordination did not change during the learning of the kick. The GE?s kick analysis demonstrated that the movement pattern of the GI?s kick was similar to the experienced ones since the beginning of the practice and that after years of practice the experts explore the freeing DF strategy too. Thus, the practice did not alter the back kick inter joint coordination and the strategy of DF reorganization during the process of learning discrete skills with speed and accuracy of movement as its purpose seems to be the thawing/freezing of DF.

Full textLe gyromètre CASI est basé sur un double interféromètre Raman aux trajectoires atomiques contrapropageantes. Cet ouvrage présente des études sur la stabilité du capteur et une amélioration de la sensibilité aux rotations d'un ordre de grandeur par rapport a l'état précédent. Une sensibilité de 2×10-8 rad/s après 4000 s de moyennage a été démontrée en exploitant, pour le corriger, la corrélation du signal de rotation avec le temps d'arrivée des échantillons atomiques.
L'expérience FORCA-G vise à réaliser des mesures de forces a faible distance à l'aide d'interféromètres Raman basés sur un effet tunnel induit par laser dans un réseau optique. Des mesures avec une sensibilité aux accélérations de 2×10-5 g/√Hz sont présentées. La sensibilité obtenue après une intégration de 150 s permettra de réaliser des mesures de la force de Casimir-Polder avec une incertitude statistique de 1 % à une distance atome-surface de l'ordre de 5 µm. Par ailleurs, l'implémentation d'un transport cohérent des atomes dans des réseaux optiques accélérés a été effectuée, qui sera utile pour les mesures futures.

Full textFalling is the second most important cause of accidental deaths in the world. These falls lead to physical injuries and psychological consequences which limit mobility especially for the elderly. Being able to prevent these events appears to be crucial and a first mandatory step is to identify the risk of fall depending on the situation (slipping, hazardous environment …). The objective of this thesis is to propose numerical tools in order to link the risk of fall to the balance perturbation. In a first part, a simple numerical model estimates if initial unbalanced states can be recovered using one recovery step. Then a focus was made on external perturbations with a specific temporal profile close to public transportation perturbations. An experimental protocol was set up due to the lack of knowledge about these perturbations. The experiment investigated the effect of the perturbation parameters on the Balance Recovery (BR) threshold. An adjustment of the previous model was made to evaluate continuous perturbations and to compare its results against our experimental findings. The final chapter developed a complementary approach based on previous work using a model predictive control scheme which aims to regulate BR strategies. This whole work contributes to highlight the BR parameters which are difficult to assess during experimental procedures. It also points out the perturbation definition which is frequently incomplete in the literature although it is the phenomenon responsible for the BR process. In order to represent more realistic human behaviors some improvements can be done such as adding noncoplanar contacts or as integrating more detailed sensorimotor aspects

Resumo: Este estudo objetivou analisar o efeito agudo de um protocolo de exercício intermitente no desempenho do chute no futsal. O estudo também buscou correlacionar o desempenho do chute com os parâmetros da função muscular de pico de torque, taxa de desenvolvimento de torque e taxa de queda de desempenho de torque a 6 e 12 segundos após o pico de torque. Dez atletas experientes de futsal (25,0 ±6,6 anos; 79,7 ±7,3 kg; 176 ±2,9 cm) foram avaliados e se verificou o pico de torque isométrico, taxa de desenvolvimento de torque isométrico e taxa de queda de desempenho de torque isométrico (6 e 12 s após pico de torque) para músculos do quadril, joelho e tornozelo. Em uma segunda sessão experimental, foi realizada a avaliação cinemática do chute (2D) durante um protocolo de exercício intermitente que consistiu em 12 "sprints" de 10 metros e 6 chutes (a cada 2 "sprints" 1 chute). Um conjunto de variáveis cinemáticas foi medido a cada chute e revelou uma queda de desempenho do chute (p<0,05) que foi caracterizada por uma menor velocidade linear do tornozelo, joelho e quadril no contato com a bola (p<0,05). As máximas velocidades lineares do tornozelo e do joelho também foram afetadas (p<0,05). A máxima velocidade angular e velocidade angular no instante de contato com a bola da coxa, joelho e tornozelo permaneceram inalterados. A máxima velocidade linear do quadril também permaneceu inalterados em resposta do protocolo de exercício intermitente. A correlação do desempenho de chute e as variáveis da função muscular (pico de torque e taxa desenvolvimento de torque) e variáveis cinemáticas apresentaram alteração sob efeito do protocolo de exercício intermitente. Nos primeiros chutes a correlação com o desempenho ocorreu com a articulação do quadril enquanto ao final do protocolo a correlação do desempenho de chute apresentou correlação com a articulação do joelho. A queda de desempenho do chute (velocidade linear do metatarso) relacionada com a variável da função muscular (taxa de queda de desempenho de torque isométrico) indicou que quanto maior a queda no desempenho dos músculos flexores dos joelhos maiores as perdas de desempenho de chute. Conclui-se que o desempenho do chute no futsal sob efeito de protocolo de exercício intermitente é alterado. Estes resultados indicam que o mesmo possivelmente ocorra durante jogos e treinos do futsal, visto característica intermitente da modalidade.
Abstract: This study aimed to analyze the accute effects of a intermittent exercise during the performance of a kick in indoor football. It was also aimed to correlate the kick performance with a number of the muscle function of peak torque, rate of torque development and rate of torque loss immediately, 6 and 12s after peak torque. Ten experienced athletes of indoor football (25,0 ±6,6 years-old; 79,7 ±7,3kg; 176 ±2,9 cm) were assessed for peak and rate of torque development of the hip, knee and ankle muscles. The rate of torque drop (immediately after, 6 and 12 s after peak torque) was also assessed. In a second experimental session, a kinematics kick assessment was performed during a prolongued intermitent exercise that consisted of 12 maximal sprints and 6 kicks every each other kick. A number of kinematic variables was assessed every kick and revealed kick performance fall (p<0,05), which was characterized by a reduced linear velocity of the ankle and knee at ball contact (p<0,05). The maximal linear velocity of the ankle and knee also showed were also affected (p<0.05). The maximal angular velocity and angular velocity at ball impact of the tight, knee and ankle of the hip remained unaltered. The maximal linear velocity of the hip also remained unchanged in response to the intermittent exercise protocol. The correlation of the kick performance and the muscle function variables (peak and rate of torque development) and the kinematic variables were altered by the intermittent protocol. In the first kicks, the correlation between the performance was detected at the hip joint, while at the end of the protocol the kick performance was correlated with the knee joint. The correlation between the kick performance and the fall in muscle torque indicated that the greater the performance fall, the greater is the fall of knee flexor muscles ability to generate torque. It was concluded that the kick performance in indoor football under the effect of a prolonged protocol that mimics game conditions is altered. These results indicate that such changes occur during the game and training sessions of indoor football, which are typical of this sport.

Full textSylvie Germain’s novels are written by a writer-thinker, being based on the Judeo-Christian tradition. Evil and the search for God are the two themes privileged by this author who does not write thesis novels, but wonders and thinks about profoundly metaphysical issues in her fiction works. Our approach is thematic, being influenced by mythocriticism and narratology. We have chosen to analyze the figures of « Grace » and « Fall » as the two poles of significance organizing the universe of Sylvie Germain’s novels. In our opinion, « Grace » is synonymous with Christian values- such as goodness, generosity, unconditional love, forgiveness, patience, faith in God, while « Fall » means moral decay in all its forms-lack of love, betrayal, lack of constraint leading to murder, incest and insanity. The three parts of our work are devoted to the epic novel, the family novel and the initiation novel. Sylvie Germain draws on the imaginary of popular literature and revisits the myths (especially the biblical ones), uses narratological structures, but at the same time she innovates in each of the above-mentioned types of novel. Her work, which is in full bloom, proposes a view upon human condition interesting for any reader because of its issues which are, after all, ethical

Full textPrevious research has identified over 60 parameters that can be used to characterise static balance, within which three groups exist: spatiotemporal, spectral and stochastic. This last group was analyzed to study its capacity to identify postural differences between two groups of elderly and control subject, its robustness and the minimal duration needed for its calculation. An analysis by nonlinear methods is carried out by using several methods to estimate entropy, such as Approximate Entropy (ApEn), Sample Entropy (SampEn) and Multi-Scale Entropy (MSE). However, these methods suffer from the presence of low-frequency components in the signals. To resolve this problem, a new method called Intrinsic Mode Entropy (IMEn) has been developed based on the Empirical Mode Decomposition (EMD) to eliminate low frequency components (IMFs). The results obtained show that this method is able to characterize postural balance and identify postural differences between groups. Finally, a simulation of the degradation of balance was carried out to make it possible to select those parameters that are able to identify a degradation of balance. Parameter selection was carried out by change-detection methods and supervised feature-selection methods. This study showed that it is possible to find several combinations of these parameters to detect a degradation of balance

Full textThis thesis deals with the problem of humanoid falling with a decoupled strategy consisting of a pre-impactand a post-impact stages. In the pre-impact stage, geometrical reasoning allows the robot to choose appropriateimpact points in the surrounding environment –that can be unstructured and may contain cluttered obstacles,and to adopt a posture to reach them while avoiding impact singularities and preparing for the post-impact. Thepost-impact stage uses a quadratic program controller that adapts on-line the joint proportional-derivative (PD)gains to make the robot compliant, i.e. to absorb post-impact dynamics, which lowers possible damage risks.We propose a new approach incorporating the stiffness and damping gains directly as decision variables in theQP along with the usually-considered variables that are the joint accelerations and contact forces. By doing so,various constraints can be added to the QP. Finally, since the gain adaptation is local, we added a preview ona time-horizon for more optimal gain adaptation based on model reduction. At each step of the development,several experiments on the humanoid robot HRP-4 in a full-dynamics simulator are presented and discussed

This study aimed to analyze the kinematic parameters during the execution of the back kick in Karate. Twelve athletes attended adults karate, male, high-yield, black belts for at least five years, affiliated to Martial Arts Association Shubu-Do. Samples were collected at Instrumentation Laboratory, CEFID-UDESC using instruments: instrumented target, contact carpet and a system of central inertial MVN Studio. To verify the normality of the data, we used the Shapiro Wilk. Proven normality we used descriptive statistics: mean, standard deviation and coefficient of variation (CV%) to describe the anthropometric variables, kinetics and kinematics. To determine the contribution of kinematic variables on the performance of the kick we used simple linear regression. The confidence level adopted in all cases was 95%. The results showed that: the athletes present values of height, leg length and body mass close to the average found in the literature. The average value of momentum was 78.06±19.84N.s and for momentum normalized by the mass of athletes the mean value was 0.98±0.18N.s.kg-1, compared to the total execution time turning the kick back found an average 0.32±0.03s, to the foot speed (m/s) during execution of the turning effort has been found dorsal an average of 10.72±1.21 m/s for the velocity of the foot at the moment of impact was observed an average of 4.13±1.44 m/s; minimum values of the angles of the knee joint during the execution of the kick were 55.214.11°, when the average impact angle of the knee joint was 79.0812.05°, relative amplitude of the knee joint was found an average 21.965.90°, of with respect to the contributions of the kinematic variables on the performance of the kick back spin, it was found that: the amplitude of the knee joint from the minimum angle has a strong correlation with the impetus to examine the individual athletes, and a moderate correlation to analyze all the athletes in sets (adjusted R2 = 0.682). Regarding the runtime kick all athletes found a moderate correlation (adjusted R2 = 120.658) with the lowest angle of the knee joint, however when analyzing the individual athletes found a strong correlation in all cases. In conclusion, the variables more related with the performance of the kick turning back were the highest amplitude of the knee joint as it relates to the impulse, and the smallest angle of the knee joint when checked the relationship with the runtime. So for better performance of the kick, the athlete should emphasize the sequential pattern of movement, rotating the trunk and hip, flexing the knee joint and ending with greater knee extension toward the target.

Comprovada a normalidade utilizou-se a estatística descritiva: média, desvio padrão e o coeficiente de variação (CV%) para descrever as variáveis antropométricas, cinética e cinemáticas. Para determinar a contribuição das variáveis cinemáticas sobre o desempenho do chute utilizou-se regressão linear simples. O nível de confiabilidade adotado em todos os casos foi de 95%. Os resultados evidenciaram que: os atletas apresentam valores de estatura, comprimento de membro inferior e massa corporal próximos à média encontrada na literatura. O valor médio obtido de impulso foi de 78,06±19,84N.s e para o impulso normalizado pela massa dos atletas o valor médio encontrado foi de 0,98±0,18 N.s.kg-1; em relação ao tempo de execução total do chute giro dorsal foi encontrado uma média 0,32±0,03s; para a velocidade máxima do pé (m/s) durante a execução do chute giro dorsal foi encontrado uma média de 10,72±1,21m/s, para a velocidade do pé no instante do impacto foi verificado uma média de 4,13±1,44m/s; os valores dos ângulos mínimos da articulação do joelho durante a execução do chute foram de 55,2714,11°; no momento do impacto a média do ângulo da articulação do joelho foi de 79,0812,05°; em relação a amplitude da articulação do joelho foi encontrado uma média de 21,965,90°. No que diz respeito às contribuições das variáveis cinemáticas sobre o desempenho do chute giro dorsal, verificou-se que: a amplitude da articulação do joelho a partir do ângulo mínimo tem uma forte correlação com o impulso ao analisar os atletas individualmente, e uma moderada correlação ao analisar todos os atletas em conjuntos (R2 ajustado = 0,682). Em relação ao tempo de execução do chute de todos os atletas encontrou-se uma moderada correlação (R2 ajustado=0,658) com o menor ângulo da articulação do joelho, entretanto ao analisar os atletas individualmente foi encontrada uma forte correlação em todos os casos. Concluindo, as variáveis com maior relação com o desempenho do chute giro dorsal foram a maior amplitude da articulação do joelho quando relacionado com o impulso, e o menor ângulo da articulação do joelho quando verificada a relação com o tempo de execução. Portanto para um melhor desempenho do chute, o atleta deverá enfatizar o padrão seqüencial de movimento, girando o tronco e quadril, flexionando a articulação do joelho e finalizando com uma maior extensão do joelho em direção ao alvo.

Full textThis study comes within the general framework of industrial facilities’ safety research. Indeed, industrial processes, notably in the nuclear field, handle hazardous materials in powder form and can produce large quantities of fugitive dust. The study of the particles resuspension from powders is of interest of first order in order to estimate the consequences of this source term of contamination on the operator, the neighbouring installations and, if necessary, the environment. Up to now, there are very few reliable data in the scientific literature on the particulate emission in case of a scenario with an accidental free fall spill of powder. The powder dustiness evaluation is carried out using coefficients obtained in experiments, or using empirical correlations. The objective of the present work is to study the influence of some parameters involved in the airborne particles production by a free fall of powder. For that purpose, experiments are carried out in order to study the influence of parameters such as the type of dischargement, the powder nature, the type of surface on which occurs the powder impaction , the system diameter used for discharge, and the falling mass. The results of mass fractions and number concentrations obtained highlighted the dominating parameters according to the type of discharge employed. Thereafter, the comparisons between our results and the empirical correlations available in the literature showed that those led to an undervaluation of the powder dustiness. This thus led us to develop, starting from the whole of experimental data, empirical correlations taking into account the various parameters studied as well as the interactions

Full textOur study focuses mainly on "Mes parents" by Hervé Guibert and on "Le mausolée des amants", the diary he derived this text from. First we situate this autobiography of his childhood in Guibert's entire work in the broad field of the autobiographical writing. Then, we examine our interpretation of "Mes parents" through the pattern of the fall. We show how the fall, which passes equally through this account of his life, the story of origins and the scenario of fantasies, ensures the cohesion of the whole. This close reading allows us to move on Guibert's writing and to perceive his originality. Although the critics refer to "Mes parents" as a genuine autobiography, the narrative makes us suspicious that the text is something more. We argue that a careful reading of "Mes parents" supports our position that this is from the writing of "Mes parents", that Guibert polished his work of literature, or rather that he systematized it. Fabricating (Guibert use this very word but its signification in French is closer to the word manufacturing) a book for Guibert is always a twofold process : he takes reality to the secret regions of his disire. This is why we believe that "Mes parents" is as much a self-mythography as an autobiography

Full textOur thesis devoted to the study of imaginary mouvements of ascension and of fall from a dialectic standpoint between the man, the world and god in the works of albert camus. As the author, who believed that he was born in total accordance with nature, is conscious of the irreversible time, the sentiment of fall and the nostalgia of the paradise lost put in motion in his imagination. The author's imagination is therefore characterized by a constant going and returning between ascension and fall. Through out the three parts of our thesis, we study this going and returning between the imaginary mouvement of ascension and that of fall : the first part is devoted to the analysis of each of the two principal imaginary mouvements of albert camus whose images regroup with two moving constellations of which one tends towards the high and the other tends towards the low, the second part to the dynamism of ascension and of fall that proceeds from a spatiotemporal plane in the five narratives works of camus, "la mort heureuse", "l'etranger", "la chute", "jonas ou l'artiste au travail" and "la femme adultere", and the third part to the research of the imaginary mouvements of ascension and of fall on the basis of the biblical images just as camus read it

Full textThis research targets the teaching and learning of the notion of free fall. It aims at developing a learning sequence intended for high school seniors and which goal is to rebuild the notion of acceleration from the notion of speed variation.The chosen methodology falls within didactic engineering of second generation. Three exploratory studies contribute to preliminary work. The first one focuses on usual practices of free fall teaching in the beginning of the 2Oth century through the analysis of physics textbooks. It shows that the study of falling bodies appears like a content at the crossroads of kinematics and dynamics. It also allows to question the added value of using vectors at the epistemological, methodological and educational level. The second study explores the ability of first year students in drawing vectors in kinematics. It highlights that the use of vectors raises difficulties and is a kinematics skill in itself. The third study is a content analysis of the notion of acceleration and its characteristics in the case of free fall. It leads to the presentation of different semiotic representation registers of acceleration.These preliminary analyses lead to the conception of a sequence which puts the vector representation at the centre of the learning system and which hypothesis is that the representation of several successive velocity vectors is a learning tool. The results show positive effects on student learning especially by enabling to deepen the knowledge of free fall and improve the skills in using vectors. These results also help to identify and describe possible measures for improvement of the learning sequence

Full textSince german unification, a "new german question" emerges, because today unified germany has become again the central country on the European continent. The liberation of central european countries and the new economic and political strength of united germany produced much fear in europe. Germany's neighbours harbour much uncertainly regarding its political role in the new europe. The gaol of this thesis is to analyse this new european preoccupation. To this end, it is necessary to study german fereign policy since the fall of the berlin-wall. Two areas are of particular importance. On the one hand, relations between germany and its community partner (part one), and on the other, those with the central and eastern european countries and sx-USSR (part two). More than ever, for germany, belonging to the european union remains of prime importance, dispite increasing contacts with the eastern european states since 1989-1990. Germany consequently provides a link between the two Europes. As chancellor kohl has emphasized, "german unity and the unity of Europe should march side by side"

Full textThe three concepts of apriority, analyticity and necessity, which have long been considered equivalent, constitute whatcould be called the “golden triangle” or “triangle of equivalence”. Yet, the Kantian conception of the synthetic a priori and the Kripkean conceptions of the contingent a priori and the necessary a posteriori represent decisive criticismsagainst this triangle of equivalence. Inheriting critically these revolutionary thoughts from Kant and Kripke, a newepistemological schema entitled “subject-knowledge-world” is here systematically constructed. This schema renders thegolden triangle totally obsolete. The concepts of apriority, analyticity and necessity become independent of each other.This leads to a new space of knowledge categories, resulting from the free intersecting of the three distinctions a priori-aposteriori, analytic-synthetic and necessary-contingent. These knowledge categories, some of which are new, apply to science exclusively and exhaustively
