Visual Feedback Postural Control Re-education
No full textMaintaining postural stability is a complex process [1] involving the coordinated actions of biomechanical, sensory, motor, and central nervous system components. A relatively simple biomechanical definition for postural stability can be formulated in terms of the position of the body center of gravity relative to the base of support. The body movements used to maintain postural stability, however, are complex because of the number of joint systems and muscles involved. The center of gravity (CoG) is the point at which the whole weight of a body may be considered to act. In humans who are standing quietly and vertically erect, the CoG is located at the level of the hips and slightly forward of the ankle joints. CoG height is 0.5527 of total height. CoG and center of mass (CoM) are equivalent points in space when the gravitational field is uniform and gravity is the only force under consideration

Tagebuch von Frau Erna Becker-Kohen 1937-1963
No full textIn the form of a diary, Becker-Kohen describes her situation as a believing Catholic, regarded by Nazis as a Jewess. With her little child she had to leave Berlin during World War II and finds various places of refuge in Austria and Southern Bavaria. Thanks to her good relations with several Catholic priests she and her little child could be hidden during the last part of the war. After the war she reunited with her husband who had to work in labor camps, where he became severely sick and died shortly afterwards.digitizedBecker-Kohen, Erna; Furtwaenglerstr. 17; 7800 Freiburg (1967).Becker-Kohen was a Jewish convert to Catholicism and married to a Catholic. She stayed in Germany during World War II, emigrated to Chile in 1952 and returned to Germany (Freiburg) in 1954
Aging and vestibular system: specific tests and role of melatonin in cognitive involvement
No full textBalance disorders are frequent with aging. They are particularly important because they decrease social autonomy of the aged subjects and they often provoke falls. The cause is always multifactorial. There is evidence that aging affects multiple sensory inputs, as well as the muscoloskeletal system and central nervous system ability to perform sensorimotor integration. For the evaluation of decreased balance skills in elderly, a specific questionnaire has been prepared, in order to identify high risk of falling called falling risk inventory (FRI) questionnaire, and a complex psycho-sensory-motor test has been studied by means of posturography, in order to detect specific vestibular impairment. Regarding ethiopathogenesis of balance disorders in aged subjects, because the decline of behavioral and cognitive performances are due also to decline of biological rhythm control, the role of melatonin (the hormone regulating circadian rhythms, being strictly connected with cerebellar function, and it is well known that cerebellum acts in elderly both at motor and cognitive regulation. The goals of the present paper are: (i) To present a self-administered FRI questionnaire aimed at identifying possible causes of falls and quantifying falling risk in aged. (ii) To validate posturography as a specific test to investigate vestibular involvement in elderly in correlation with FRI. (iii) To present a complex behavioral test (NT) aimed at evaluating both spatial orientation and spatial memory in elderly, factors involved into the genesis of complex dizziness and unsteadiness. (iv) To evaluate the role of melatonin in cognitive involvement in dizzy, old subjects due to the functional correlations between circadian rhythms, cerebellum balance disturbances and cognitive disorders. General conclusions are: FRI correlates with falling risk. Posturography identifies specific vestibular impairments correlated to balance disorders and elderly falls. Spatial orientation is altered in about 40% of dizzy patients but no significant differences are revealed in melatonin rhythm. Spatial memory is highly altered only in subjects with inversion of circadian melatonin rhythm it is possible to hypothesize that the alteration of the normal circadian melatonin rhythm plays some role in the genesis of dizziness in a subpopulation of patients

No full textThe subjects of this experiment were about ten unstable children. It was shown that the statokinesimetric and ataxiametric technics were convergent. It was suggested that the relationships between the subjects unstable behavior (of a neurological nature) and their reading difficulties due to an oculo-motor deficiency. This deficiency resulted in strategies of learning to read that were more time-consuming than the strategies children normally employ.La recherche a porté sur une dizaine d'enfants instables. Elle a montré que les techniques statokinésimétriques et ataxiométriques sont convergentes. Elle suggère que les relations entre l'instabilité comportementale d'origine neurologique et les difficultés en lecture sont dues à une insuffisance oculo-motrice. Cette insuffisance provoquerait des stratégies d'apprentissage de la lecture plus coûteuses que les stratégies habituellement 'utilisées par l'enfant.Bijeljac-Babic Ranka, Hiriartborde E., Kohen-Raz Reuven.

On Waldron\u27s Critique of Raz on Human Rights
No full textThis commentary responds to Waldron’s “Human Rights: A Critique of the Raz/Rawls Approach”. It points out that some supposed criticisms are nothing more than observations on conditions that any account of rights must meet, and that Waldron’s objections to Raz are due to misunderstanding his thesis and its theoretical goal. The short comment tries to clarify that goal

Le développement du droit international : réflexions d’un demi-siècle. Volume I
No full textDès le début des années 1960, les écrits du professeur Abi-Saab nous ont accompagnés pour nous faire découvrir les évolutions successives de l’ordre juridique international, en réponse aux grands mouvements et courants d’idées qui ont traversé le monde : la grande vague de libération nationale, qui a projeté sur le devant de la scène le principe du droit des peuples à disposer d’eux-mêmes et qui a permis à l’ONU de jouer un rôle grandissant dans l’élaboration et la mise en œuvre de ce droit ainsi que dans le règlement des conflits issus des luttes de libération nationale ; l’impact de l’expansion de la communauté internationale qui s’en est suivie, sur les structures et les normes du droit international ; la quête, au sein de cette communauté internationale devenue universelle, de plus de justice sociale à travers un Nouvel ordre économique international et un droit au développement. Depuis la Genève internationale, le professeur Abi-Saab a su influencer plusieurs générations de juristes, venant de divers horizons et cultures, par ses analyses originales des grands thèmes du droit international : ses structures, ses sources, ses sujets principaux ; ainsi que des domaines plus spécifiques, tels le droit humanitaire ou le droit économique international. À l’occasion du 80e anniversaire du professeur Abi-Saab en 2013, le professeur Marcelo Kohen et M. Magnus Jesko Langer ont réuni dans cet ouvrage une sélection d’articles publiés en français par Georges Abi-Saab, qui ne sont pas toujours facilement disponibles. Ils retracent la pensée d’un grand maître du droit international de ce dernier demi-siècle
