El rol del control personal en la función paliativa de la justificación del sistema entre la población indígena y no indígena de estudiantes peruanos
Indexación: Scopus.In this article we propose a mediation model for the association between system justification and psychological well-being (i.e., the palliative function of ideology), based on system justification theory and compensatory control theory. Specifically, we argue that endorsing system-justifying beliefs leads to increased perceived personal control, which in turn predicts higher well-being. We used a convenience sample of students from two Peruvian universities. The results showed that system justification was related to general psychological well-being and personal control. In addition, indigenous students rated lower on system justification, general psychological well-being, self-esteem and personal control. Next, we found that the association between system justification and general psychological well-being was stronger among indigenous students, and this relationship was partially mediated by personal control. In addition, we showed that the mediation model is moderated by ethnicity, so that personal control is a mediator only among non-indigenous participants. We conclude that personal control is a mechanism involved in the palliative function of ideology among this group. Finally, we discuss possible explanations for the mechanisms involved in the palliative function of ideology among low-status individuals. © 2018, © 2018 Fundacion Infancia y Aprendizaje.En este artículo se propone un modelo de mediación de las
relaciones entre la justificación del sistema y el bienestar psicológico (i.e.,
la función paliativa de la ideología) basado en las teorías de la justificación
del sistema y del control compensatorio. En concreto, se propone que la
adopción de creencias justificativas del sistema produce un aumento del
control personal percibido que, a su vez, predice niveles más elevados de bienestar. En este estudio se utilizó una muestra por conveniencia de estudiantes
provenientes de dos universidades peruanas. Los resultados muestran
que la justificación del sistema está relacionada con el bienestar psicológico
general y con el control personal. Además, los estudiantes indígenas mostraron
niveles más reducidos de justificación del sistema, bienestar
psicológico general, autoestima y control personal. También se observó que
la relación entre la justificación del sistema y el bienestar psicológico general
era más fuerte entre los estudiantes indígenas y que el control personal
mediaba parcialmente en esta relación. Asimismo, mostramos que la etnicidad
es un factor moderador del modelo de mediación, por lo que el control
personal es un mediador únicamente entre los participantes no indígenas. El
estudio concluye que el control personal es un mecanismo que interviene en
la función paliativa de la ideología en este grupo. Por último, se discuten
posibles explicaciones de los mecanismos implicados en la función paliativa
de la ideología entre individuos de estatus social bajo.https://www.tandfonline.com/doi/full/10.1080/02134748.2018.153765
Description sensorielle de la carotte - recherche et mise au point d'une méthodologie
En évaluation sensorielle, la description des caractéristiques organoleptiques d\u27un produit par la méthode de profil sensoriel demande, dans un premier temps, de déterminer les descripteurs qui vont être pertinents dans la caractérisation du produit. Cet article présente les différentes étapes de mise en place d\u27une liste de descripteurs appliquée à la carotte. La carotte étant un produit consommé cru ou cuit et sous différentes formes, trois modes d\u27usage (carotte crue râpée, cuite entière, crue en rondelle...) vont être comparés, afin de déterminer quel est l\u27apport de chacune des méthodes dans la description du produit

Spectral plots and the representation and interpretation of biological data
It is basic question in biology and other fields to identify the char-
acteristic properties that on one hand are shared by structures from a
particular realm, like gene regulation, protein-protein interaction or neu- ral
networks or foodwebs, and that on the other hand distinguish them from other
structures. We introduce and apply a general method, based on the spectrum of
the normalized graph Laplacian, that yields repre- sentations, the spectral
plots, that allow us to find and visualize such properties systematically. We
present such visualizations for a wide range of biological networks and compare
them with those for networks derived from theoretical schemes. The differences
that we find are quite striking and suggest that the search for universal
properties of biological networks should be complemented by an understanding of
more specific features of biological organization principles at different
scales.Comment: 15 pages, 7 figure
Organoleptic quality of the carrot. Importance of variety and location of production in the perception of sensory quality of carrot
Variation factors involved in carrot sensory appreciation
Sensory analysis is an indispensable tool for understanding the consumers and promoting segmentation in a product such as the carrot.
However, one must have first a good knowledge of the sensory space of the carrot, and identify the sources of variation involved in the sensory characterization. Trials were conducted on two years in 2010 and 2011 and two production sites in France. The overall sensory space was characterized from 48 batches representing a wide genetic diversity. This has enabled us to identify varieties that opposed the main criteria i.e. texture, including juicy trait, sweet perception and the potential of bitterness, spicy and chemical aroma.
On a smaller sample of orange carrot, two years of tests have highlighted variations due to the production site and varieties, which were modulated by annual differences.
The observed variation underlines the need for more research on explaining the causes such as the development cycle and the pedoclimatic conditions.
Elliptic Thermal Correlation Functions and Modular Forms in a Globally Conformal Invariant QFT
Global conformal invariance (GCI) of quantum field theory (QFT) in two and
higher space-time dimensions implies the Huygens' principle, and hence,
rationality of correlation functions of observable fields (see Commun. Math.
Phys. 218 (2001) 417-436; hep-th/0009004). The conformal Hamiltonian has
discrete spectrum assumed here to be finitely degenerate. We then prove that
thermal expectation values of field products on compactified Minkowski space
can be represented as finite linear combinations of basic (doubly periodic)
elliptic functions in the conformal time variables (of periods 1 and )
whose coefficients are, in general, formal power series in
involving spherical functions of the "space-like"
fields' arguments. As a corollary, if the resulting expansions converge to
meromorphic functions, then the finite temperature correlation functions are
elliptic. Thermal 2-point functions of free fields are computed and shown to
display these features. We also study modular transformation properties of
Gibbs energy mean values with respect to the (complex) inverse temperature
(). The results are used to obtain the
thermodynamic limit of thermal energy densities and correlation functions.Comment: LaTex. 56 pages. The concept of global conformal invariance set in a

Qualité organoleptique de la carotte : variabilité des critères sensoriels selon le type variétal
La différenciation gustative est une voie possible de segmentation. L\u27étude a porté sur la variabilité des critères sensoriels dans le matériel végétal. Trente-trois varié - tés des types Nantais, Imperator, Flakkee, de carottes de couleur et de ressources génétiques ont été caractérisées en analyse sensorielle descriptive quantitative et par des mesures physico-chimiques. Des différences significatives pour tous les critères existent et permettent de regrouper les variétés sur la base de leurs caractéristiques sensorielles. Texture, saveur et arôme contribuent à la typicité de la carotte ; l\u27arôme global est corrélé aux perceptions d\u27amer, de piquant et d\u27arôme chimique. La mesure des sucres ne permet pas d\u27évaluer la perception en bouche du sucre du fait de l\u27influence du potentiel d\u27amertume
