Le pardon dans la Bible hébraïque

Dans la Bible hébraïque, le pardon joue un rôle dans des genres littéraires différents tels que les narratifs des patriarches, les textes législatifs, ainsi que les textes de réflexions théologiques. Plusieurs expressions s'y réfèrent : à part le verbe technique sālaḥ « pardonner », il y a également des termes métaphoriques comme « enlever», « faire passer », « éponger » et « nettoyer le péché », ou encore « ne plus s'en souvenir ». Sujet de l'acte du pardon est soit l'homme soit Dieu. Le thème du pardon est étroitement lié à celui de la transgression des normes et lois de la société comme de la religion de l'Ancien Israël. Les transgressions graves sont en principe impardonnables : elles créent une sphère du mal qui affecte tout l'environnement et peut entraîner des maladies, des incidents malencontreux, etc. En principe, cet effet perdure et ne cesse pas automatiquement, sauf si la transgression est sanctionnée d'une manière adéquate. Les sanctions se font selon les principes de la compensation, de la restitution et de la prévention : dans une ancienne collection de lois, le Code d'Alliance, le meurtre a ainsi pour conséquence la mise à mort de l'auteur du délit (cf. Ex 21,12) et le boeuf volé doit être restitué cinq fois (cf. Ex 21,37). Pour certains cas de transgressions, et sous certaines conditions, il y avait cependant des possibilités de protéger le délinquant et de substituer ou de réduire une sanction sévère prévue, voire d'y renoncer complètement. Cet article donne tout d'abord un aperçu du pardon accordé par l'homme et résume dans une deuxième partie les conceptions concernant l'arbitrage et le pardon de Dieu.

Interventions présumées des scribes concernant le motif de l'arbre sacré dans le Pentateuque

Abstract: This article deals with several presumed scribal interventions which all concern the sacred tree motif. One finds deliberate changes in the MT, in the Septuagint, in Targum Onkelos and in the Vulgate. The Greek translators of Genesis and Samuel (1-2 Kingdoms) avoided rendering the word אשׁל "tamarisk" by its equivalent μυρίκη, chosing instead the word ἄρουρα "field". Similarly, the Greek translator of Genesis, in the passage of the death of Rebecca's nurse Deborah, passed over the motif of her burial under a grand tree. According to the hypothesis of the present article, all four changes are related to one other; they might be due to the translator's fear to connect the respective texts with traditions and customs concerning the Egyptian god Osiris. On the other side, a scribe of the proto-Massoretic tradition modified the readings mentioning the large tree of Mamre close to Hebron. By changing the noun's number from singular to plural the corrector tried to conceal the existence and importance of the sacred tree in the tradition of Abraham. By contrast, the scribe did not modify texts related to the sacred tree of Shechem. This disparity of treatment may be explained by the fact that, in the view of the Judean scribe, the tree of Shechem would put the Samaritans in a bad light. Finally, the authors of Targum Onkelos and of the Vulgate intervened almost systematically in Pentateuchal texts having the terms אֵלוֹן) אלון or אַלּוֹן ), which always designate a holy tree. The two expressions are rendered by terms referring to plains (Targum Onkelos) or a valley (Vulgate).

El cervell té mecanismes per a les metàfores

Al cervell li costa entendre i generar metàfores. Comprendre el llenguatge figuratiu implica necessàriament la utilització simultània de diversos circuits neurals, que han d"extreure informació no literal a partir de paraules que tanmateix també tenen un significat concret. Per entendre aquesta facultat exclusivament humana, Nira Mashal i els seus col·laboradors, de la Universitat Ben-Ilan de Ramat Gan i del centre de salut mental Aviv-Brull de Tel Aviv, a Israel, han monitoritzat el funcionament del cervell en un grup de voluntaris mentre comprenien metàfores o expressions literals, i l"han comparat amb el de malalts d"esquizofrènia, una patologia que es caracteritza, entre altres aspectes, per la incapacitat d"entendre-les.

Optimización y aproximación al problema de la regresión simbólica a través de Straight Line Programs (SLP's) y algoritmos genéticos : Entrenamiento genético de SLP's

El problema de la regresión simbólica consiste en el aprendizaje, a partir de un conjunto muestra de datos obtenidos experimentalmente, de una función desconocida. Los métodos evolutivos han demostrado su eficiencia en la resolución de instancias de dicho problema. En este proyecto se propone una nueva estrategia evolutiva, a través de algoritmos genéticos, basada en una nueva estructura de datos denominada Straight Line Program (SLP) y que representa en este caso expresiones simbólicas. A partir de un SLP universal, que depende de una serie de parámetros cuya especialización proporciona SLP's concretos del espacio de búsqueda, la estrategia trata de encontrar los parámetros óptimos para que el SLP universal represente la función que mejor se aproxime al conjunto de puntos muestra. De manera conceptual, este proyecto consiste en un entrenamiento genético del SLP universal, utilizando los puntos muestra como conjunto de entrenamiento, para resolver el problema de la regresión simbólica.

Classificação e definição dos métodos de análises em fluxo (Recomendações - IUPAC 1994)

The aim of this report is to classify analytical methods based on flowing media and to define (standardize) terminology. After the classification and a discussion of terms describing the systems and component parts, a section is devoted to terms describing the performance of flow systems. The list of terms included is restricted to the most relevant ones; especially "self-explanatory" terms are left out. It is emphasised that the usage of terms or expressions that do not adequately describe the processes or procedures involved should be strongly discouraged. Although belonging to the category of methods based on flowing media, chromatographic methods are not comprised in the present document. However, care has been taken that the present text is not in conflict with definitions in that domain. In documents in which flow methods are described, it should be clearly indicated how the sample and/or reagent is introduced and how the sample zone is transported. When introducing new techniques in the field, or variants of existing techniques, it is strongly recommended that descriptive terms rather than trivial or elaborate names are used.

Garvey-Kelson relations for nuclear charge radii

The Garvey-Kelson relations (GKRs) are algebraic expressions originally developed to predict nuclear masses. In this letter we show that the GKRs provide a fruitful framework for the prediction of other physical observables that also display a slowly-varying dynamics. Based on this concept, we extend the GKRs to the study of nuclear charge radii. The GKRs are tested on 455 out of the approximately 800 nuclei whose charge radius is experimentally known. We find a rms deviation between the GK predictions and the experimental values of only 0.01 fm. This should be contrasted against some of the most successful microscopic models that yield rms deviations almost three times as large. Predictions -with reliable uncertainties- are provided for 116 nuclei whose charge radius is presently unknown.

Compartir ritunes sincronitza els cervells

Un dels pilars fonamentals de totes les societats humanes que permet el seu funcionament i la cohesió dels seus membres és la capacitat d'entendre's. La comunicació entre persones s'estableix utilitzant formes verbals i no verbals a través de les paraules i també de gesticulacions, expressions facials, etc. Tots els sistemes humans de comunicació, però, presenten un alt grau d'ambigüitat pel que fa a la interpretació. Com aconseguim entendre'ns entre nosaltres? O, dit d'una altra manera, ¿de quina manera l'activitat neural del cervell contribueix a compartir el significat del que comuniquem?

Impedance field and noise of submicrometer n+ nn+ diodes: analytical approach

A theoretical model for the noise properties of n+nn+ diodes in the drift-diffusion framework is presented. In contrast with previous approaches, our model incorporates both the drift and diffusive parts of the current under inhomogeneous and hot-carrier conditions. Closed analytical expressions describing the transport and noise characteristics of submicrometer n+nn+ diodes, in which the diode base (n part) and the contacts (n+ parts) are coupled in a self-consistent way, are obtained

Bias and standard error for social reciprocity measurements

The directional consistency and skew-symmetry statistics have been proposed as global measurements of social reciprocity. Although both measures can be useful for quantifying social reciprocity, researchers need to know whether these estimators are biased in order to assess descriptive results properly. That is, if estimators are biased, researchers should compare actual values with expected values under the specified null hypothesis. Furthermore, standard errors are needed to enable suitable assessment of discrepancies between actual and expected values. This paper aims to derive some exact and approximate expressions in order to obtain bias and standard error values for both estimators for round-robin designs, although the results can also be extended to other reciprocal designs.

New approximation to the third-order density : application to the calculation of correlated multicenter indices

In this work we present the formulas for the calculation of exact three-center electron sharing indices (3c-ESI) and introduce two new approximate expressions for correlated wave functions. The 3c-ESI uses the third-order density, the diagonal of the third-order reduced density matrix, but the approximations suggested in this work only involve natural orbitals and occupancies. In addition, the first calculations of 3c-ESI using Valdemoro's, Nakatsuji's and Mazziotti's approximation for the third-order reduced density matrix are also presented for comparison. Our results on a test set of molecules, including 32 3c-ESI values, prove that the new approximation based on the cubic root of natural occupancies performs the best, yielding absolute errors below 0.07 and an average absolute error of 0.015. Furthemore, this approximation seems to be rather insensitive to the amount of electron correlation present in the system. This newly developed methodology provides a computational inexpensive method to calculate 3c-ESI from correlated wave functions and opens new avenues to approximate high-order reduced density matrices in other contexts, such as the contracted Schrödinger equation and the anti-Hermitian contracted Schrödinger equation

Coordenadas cartesianas moleculares a partir da geometria dos modos normais de vibração

A simple method to obtain molecular Cartesian coordinates as a function of vibrational normal modes is presented in this work. The method does not require the definition of special matrices, like the F and G of Wilson, neither of group theory. The Eckart's conditions together with the diagonalization of kinetic and potential energy are the only required expressions. This makes the present approach appropriate to be used as a preliminary study for more advanced concepts concerning vibrational analysis. Examples are given for diatomic and triatomic molecules.

Prognostic Markers and Prolonged Interferon-alpha Therapy in Renal Cell Carcinoma

Molekyylimarkkerit ja pitkäaikainen alfainterferonihoito munuaissyövässä Munuaissyöpäpotilaiden viiden vuoden elossaololuku on noin 50 %. Aikaisempien tutkimuksien mukaan viiden vuoden elossaololuku metastasoituneessa munuaissyövässä on 3-16 %, kun käytettiin alfainterferonia sisältävää hoitoa. Tyypillisesti alfainterferonia on käytetty vähemmäin kuin 6 kuukautta. Avoimia kysymyksiä ovat alfainterferonin optimaalinen hoitoannos ja hoidon kesto yksin tai yhdessä uusien täsmähoitojen kanssa. Tärkeimmät tavoitteet olivat tutkia 1) jaksotetun pitkäaikaisen alfainterferonihoidon tehoa ja siedettävyyttä metastasoituneessa munuaissyövässä ja 2) p53-, Ki-67- ja COX-2-proteiinituotannon ennusteellista merkitystä munuaissyövässä. Tutkimuksessa 117 metastasoituneelle munuaissyöpää sairastaneelle potilaalle etsittiin yksilöllinen hänen sietämänsä maksimaalinen hoitoannos rekombinanttia alfa2a-interferonia (Roferon-ATM). Hoitoa pyrittiin jatkamaan 24 kuukauden ajan. Kolmen hoitoviikon jälkeen pidettiin yhden viikon tauko. Hoito lopetettiin, jos ilmaantui vakavia haittavaikutuksia tai tauti eteni. Toisessa tutkimuksessa proteiinituotanto analysoitiin immunohistokemiallisesti munuaissyöpäpotilaiden kasvainnäytteistä, joita oli säilytetty parafiinissa. Kasvainnäytteet oli otettu talteen munuaisen poistoleikkauksen yhteydessä. Nämä potilaat jaettiin kolmeen eri ryhmään: metastasointi primaarivaiheessa (n=29), metastasointi myöhemmin (n=37) ja ei metastasointia (n=51). Keskimääräinen alfainterferonihoidon kesto oli 11 kuukautta (kk) [0,5 – 32 kk]. Objektiivinen hoitovaste todettiin 17 %:lla, tautitilanne pysyi ennallaan 42 %:lla ja myöhäinen vaste (yli 12 kk:tta hoidon aloittamisesta) todettiin 3 %:lla. Aika vasteen saavuttamisesta taudin etenemiseen oli keskimäärin 8 kk ja elinaika 19,1 kk. Viiden vuoden elossaololuku oli 16 %. Jos metastasoituneella munuaissyöpäpotilaalla oli keuhkometastasointi, hän selvisi todennäköisemmin viisi vuotta kuin muut potilaat. Henkeä uhkaavia sivuvaikutuksia ei todettu. Yli 12 kk:n ajan kestävä alfainterferonihoito on hyödyllistä niille potilaille, jotka ovat saaneet objektiivisen hoitovasteen tai tautitilanne on pysynyt ennallaan. Positiivinen p53- ja Ki-67-ekspressio yhdessä viittaavat suureen metastasoinnin todennäköisyyteen. Positiivinen COX-2-ekspressio viittaa viivästyneeseen metastaasien ilmaantumiseen. Metastasoituneilla potilailla positiiviset p53- ja Ki-67-ekspressiot viittaavat huonoon ennusteeseen, mutta positiivinen COX-2 ekspressio viittaa suotuisaan ennusteeseen. Positiivinen COX-2- ja negatiivinen Ki-67-ekspressio yhdessä viittaavat parantuneeseen ennusteeseen metastasoituneessa munuaissyövässä.

Children's understanding of pretend emotions

This preliminary study aims to investigate children’s ability to understand that the emotional expressions that occur in pretend play do not necessarily coincide with the emotions people feel inside. Previous research has found that children aged 4 and 6 have difficulty to distinguish between the external and the internal emotion of a character who pretends an emotion. In the present work, thirteen 4-year-olds and eight 6-year-olds were administered stories in which a character simulated an emotion. Differently from previous research, the questions addressed to the children did not focus on the distinction external/internal emotion but on the distinction between real/pretend emotion. Furthermore, since previous research has suggested that children may understand better selfpretence than pretence of others, the participants in our study were engaged in a pretence situation where they had to pretend to be happy. The results obtained showed that, contrary to previous research, most 4- and 6-year-olds realize that pretend emotions may not be real, and this was true both for self-pretence and for the pretence of others
