Published: January 2020

El propósito de este estudio es analizar si se han producido cambios en la construcción del sí mismo, en la estructura cognitiva y en la sintomatología ansiosa-depresiva en 19 pacientes diagnosticadas de trastorno distímico tras realizar seis meses de terapia de grupo. Un segundo objetivo que nos hemos planteado, ha sido analizar con medidas test y retest si en una muestra no clínica, pareada en edad, nivel de estudios y ocupación con la muestra clínica, ha habido cambios en la construcción del sí mismo, en la estructura cognitiva tras un lapso de tiempo a los seis meses. Para evaluar estos cambios hemos utilizado la Técnica de la Rejilla de Kelly, el Inventario de Ansiedad Estado-Rasgo (STAI), el Inventario de Depresión de Beck (BDI) y la Escala de Autoestima de Rosemberg. Los resultados revelan que los pacientes con trastorno distímico, tras la terapia de grupo, han tenido un cambio en la construcción del sí mismo y en su estructura cognitiva, no encontrándose este tipo de cambios en la muestra no clínica. Además, en la muestra clínica también se ha obtenido una disminución del nivel de ansiedad y de depresión, junto con un aumento del nivel de autoestima.

Abstract: Acute lymphoblastic leukemia (LLA) is the most common type of leukemia in children. Until now chemotherapy is still used as the main treatment. One aspect that affects the success of chemotherapy is body mass index (BMI). BMI values in children with LLA tend to be unstable, low, or high. This is triggered by natural immune cell disorders which have an impact on increasing cytokines and side effects of treatment. This study was aimed to determine the relationship between BMI and the achievement of remission in children with ALL. This was a retrospective and analytical study with a cross-sectional design. Samples were ALL patients who had been given induction phase of chemotherapy during 2015-2018 based on medical records at Estella Children's Cancer Center, Prof. Dr. R. D. Kandou Hospital Manado. The results obtained 52 samples which were evaluated and analyzed to determine the relationship of BMI and the achievement of remission. The Spearman correlation test showed a significant value of p=0.799 (p>0.05). In conclusion, there was no relationship between BMI and the achievement of remission in children with ALLKeywords: body mass index, remission, acute lymphoblastic leukemia Abstrak: Leukemia limfoblastik akut (LLA) merupakan jenis leukemia yang paling sering terjadi pada anak-anak. Sampai saat ini kemoterapi masih dipakai sebagai pengobatan utama. Salah satu aspek yang memengaruhi keberhasilan kemoterapi yaitu indeks massa tubuh (IMT). Nilai IMT pada anak penderita LLA cenderung tidak stabil, bisa kurang tetapi juga lebih. Hal ini dipicu oleh gangguan sel imun alami yang dialami penderita kemudian berdampak terhadap peningkatan sitokin serta efek samping pengobatan. Penelitian ini bertujuan untuk mengetahui hubungan antara IMT dan tercapainya remisi pada anak penderita LLA. Jenis penelitian ialah analitik retrospektif dengan desain potong lintang. Sampel penelitian ialah pasien LLA yang telah diberikan kemoterapi fase induksi periode 2015-2018, didapatkan dari rekam medik di Pusat Kanker Anak Estella RSUP Prof Dr. R. D. Kandou Manado. Hasil penelitin mendapatkan 52 sampel, kemudian dievaluasi dan dianalisis untuk melihat hubungan IMT dan tercapainya remisi pada sampel. Hasil uji korelasi Spearman menunjukkan nilai p=0,799 (p>0,05). Simpulan penelitian ini ialah tidak terdapat hubungan antara IMT dan tercapainya remisi pada anak penderita LLA.Kata kunci: Indeks massa tubuh, remisi, leukemia limfoblastik akut

Published: January 2020

The purpose of this quantitative study was to investigate the relationship between academic outcomes and locus control beliefs among high school students in the Northern Region of Ghana. Using survey methods and multivariate analyses, the results found relatively higher scores in external locus of control beliefs than internal locus of control beliefs among the study participants. External locus of control was inversely related to test scores, and no relationship was found between internal locus of control beliefs and test scores. The results also found significant differences in locus of control beliefs between rural and urban high school students, with urban students reporting higher internal locus of control beliefs than their rural counterparts. Implications for educational policy and practice are discussed.

ABSTRACT
Turquoise, CuAl6(PO4)4(OH)8·4H2O, belongs to the turquoise group, which consists of turquoise, chalcosiderite, aheylite, faustite, planerite, and UM1981-32-PO:FeH. In order to study turquoise-group solid solutions in samples from the Neyshabour and Meydook mines, 17 samples were selected and investigated using electron probe microanalysis. In addition, their major elements were compared in order to evaluate the feasibility of distinguishing the provenance of Persian turquoises. The electron microprobe data show that the studied samples are not constituted of pure turquoise (or any other pure endmember) and belong, from the chemical point of view, to turquoise-group solid solutions.
In a turquoise–planerite–chalcosiderite–unknown mineral quaternary solid solution diagram, the chemical compositions of the analyzed samples lie along the turquoise–planerite line with minor involvement of chalcosiderite and the unknown mineral. Among light blue samples with varying hues and saturations from both studied areas, planerite is more abundant among samples from Meydook compared with samples from Neyshabour. Nevertheless, not all the light blue samples are planerite. This study demonstrates that distinguishing the deposit of origin for isochromatic blue and green turquoises, based on electron probe microanalysis method and constitutive major elements, is not possible.
Good vibrations: A review of vocal expressions of positive emotions
Authors: Kamiloğlu Roza G. , Fischer Agneta H. , Sauter Disa A. 
Published: January 2020

AbstractResearchers examining nonverbal communication of emotions are becoming increasingly interested in differentiations between different positive emotional states like interest, relief, and pride. But despite the importance of the voice in communicating emotion in general and positive emotion in particular, there is to date no systematic review of what characterizes vocal expressions of different positive emotions. Furthermore, integration and synthesis of current findings are lacking. In this review, we comprehensively review studies (N= 108) investigating acoustic features relating to specific positive emotions in speech prosody and nonverbal vocalizations. We find that happy voices are generally loud with considerable variability in loudness, have high and variable pitch, and are high in the first two formant frequencies. When specific positive emotions are directly compared with each other, pitch mean, loudness mean, and speech rate differ across positive emotions, with patterns mapping onto clusters of emotions, so-called emotion families. For instance, pitch is higher for epistemological emotions (amusement, interest, relief), moderate for savouring emotions (contentment and pleasure), and lower for a prosocial emotion (admiration). Some, but not all, of the differences in acoustic patterns also map on to differences in arousal levels. We end by pointing to limitations in extant work and making concrete proposals for future research on positive emotions in the voice.
Turbulent Viscosity Acting on the Equilibrium Tidal Flow in Convective Stars
Authors: Vidal Jérémie , Barker Adrian J. 
Published: January 2020

Abstract
Convection is thought to act as a turbulent viscosity in damping tidal flows and in driving spin and orbital evolution in close convective binary systems. This turbulent viscosity should be reduced, compared to mixing-length predictions, when the forcing (tidal) frequency

exceeds the turnover frequency ω

cv
of the dominant convective eddies. However, two contradictory scaling laws have been proposed and this issue remains highly disputed. To revisit this controversy, we conduct the first direct numerical simulations of convection interacting with the equilibrium tidal flow in an idealized global model of a low-mass star. We present direct computations of the turbulent effective viscosity, ν

E
, acting on the equilibrium tidal flow. We unexpectedly report the coexistence of the two disputed scaling laws, which reconciles previous theoretical (and numerical) findings. We recover the universal quadratic scaling

in the high-frequency regime

. Our results also support the linear scaling

in an intermediate regime with

. Both regimes may be relevant to explain the observed properties of close binaries, including spin synchronization of solar-type stars and the circularization of low-mass stars. The robustness of these two regimes of tidal dissipation, and the transition between them, should be explored further in more realistic models. A better understanding of the interaction between convection and tidal flows is indeed essential to correctly interpret observations of close binary stars and short-period planetary orbits.
Symmetries of CMB Temperature Correlation at Large Angular Separations
Authors: Hagimoto Ray , Hogan Craig , Lewin Collin , Meyer Stephan S. 
Published: January 2020

Abstract
A new analysis is presented of the angular correlation function C(Θ) of cosmic microwave background temperature at large angular separation, based on published maps derived from Wilkinson Microwave Anisotropy Probe and Planck satellite data, using different models of astrophysical foregrounds. It is found that using a common analysis, the results from the two satellites are very similar. In particular, it is found that previously published differences between measured values of C(Θ) near Θ = 90° arise mainly from different choices of masks in regions of largest Galactic emissions, and that demonstrated measurement biases are reduced by eliminating masks altogether. Maps from both satellites are shown to agree with C(90°) = 0 to within estimated statistical and systematic errors, consistent with an exact symmetry predicted in a new holographic quantum model of inflation.
Duffing Oscillator Model of Solar Cycles
Authors: Nagovitsyn Yury A. , Pevtsov Alexei A. 
Published: January 2020

Abstract
We propose that the solar cycle variability could be described in the framework of an external quasi-sinusoidal influence on an oscillator with cubic nonlinearity and linear damping (Duffing oscillator). To demonstrate this, we compare the empirical amplitude–frequency dependence with the theoretical one obtained by the Krylov–Bogolyubov averaging method. The empirical data are a composite time series of 2.0 version of sunspot number series, which starts in 1700, and the sunspot group number series by Svalgaard & Schatten, scaled to sunspot number, for 1610–1699 interval. We find that while this interpretation of solar cycle is a mathematical approximation, it explains several properties of solar cycle variability.

Après l’élection de Donald Trump, d’aucuns imaginaient que sa rhétorique de campagne xénophobe, islamophobe et sexiste laisserait place à un mode de gouvernement traditionnel axé sur les enjeux économiques. Mais il n’est finalement pas un « président-homme d’affaires ». Pour comprendre la présidence Trump, il faut l’analyser sous le prisme de la politique identitaire.
Donald Trump aux prises avec le Congrès : un leadership en trompe-l’œil
Authors: Vergniolle de Chantal François 
Published: January 2020

Faut-il voir dans la présidence Trump un renouveau de la « présidence impériale », dénoncée en son temps par Arthur Schlesinger ? Les postures de Donald Trump inciteraient à y voir une forme d’autoritarisme, mais cette présidence est au contraire le symptôme d’un système politique polarisé, déchiré par des clivages partisans, où l’exécutif est bien souvent bloqué dans ses entreprises. Si sous Barack Obama se sont aussi illustrées les limites du pouvoir présidentiel dans un contexte partisan polarisé, sous Donald Trump se révèle ce qui se passe quand la présidence est elle-même polarisée : elle n’est plus que l’ombre de la présidence héritée du New Deal . Dès lors, la capacité plébiscitaire du locataire de la Maison-Blanche semble se limiter à la mobilisation d’une base électorale étroite par le biais des réseaux sociaux et à la multiplication des fiats administratifs.
Vers une convergence internationale des réglementations en matière de sûreté nucléaire ?
Authors: Rigail Anne-Cécile , Collet Julien 
Published: January 2020

L’industrie nucléaire présente un caractère « national » très marqué. Pour autant, les cadres d’échanges internationaux sont très nombreux et la plupart se proposent de favoriser la convergence des réglementations entre les pays. Deux moteurs « faibles » d’une telle convergence sont, d’une part, le souhait des industriels de disposer de règles uniformes pour leurs projets d’export et, d’autre part, l’attente par l’opinion publique de l’instauration d’exigences de sûreté ambitieuses dans tous les pays du monde. Les efforts menés par la France, notamment à l’échelle européenne, puis internationale, ont permis de « tirer vers le haut » les exigences de sûreté, mais ces efforts atteignent leurs limites dans un monde multipolaire, où les grandes puissances ne souhaitent pas alourdir les exigences applicables à leurs champions nationaux, et où chaque pays nucléarisé réaffirme son souhait de garder la pleine maîtrise de cette industrie.
Comment développer la transparence et la participation dans le domaine du nucléaire civil ?
Authors: Delalonde Jean-Claude 
Published: January 2020

Transparence, expertises pluralistes, participation aux décisions… où en sommes-nous dans l’application des textes réglementaires internationaux, européens et français ? La société civile a-t-elle su s’emparer de son droit d’accès à l’information et de participation aux décisions pour comprendre, participer et interagir dans le domaine du nucléaire ? L’ANCCLI dresse un état des lieux des outils réglementaires créés à cet effet et s’interroge sur la manière dont la société civile et les acteurs du nucléaire se les sont appropriés ces dernières années, pour en faire de véritables outils d’action : quels sont les constats positifs qui en sont ressortis, les points de vigilance et les points d’amélioration ? Entre l’urgence de trouver une solution qui est souvent mise en avant et la nécessité de prendre le temps de s’informer, de monter en compétence et de se concerter, la société civile est en attente de davantage de sincérité, voire d’humilité de la part des acteurs du nucléaire. Mais elle est aussi et surtout soucieuse que sa participation soit effectivement prise en compte dans la prise de décision.
Témoignage du maire d’une commune accueillant une centrale nucléaire

Construit entre 1975 et 1985, le centre nucléaire de production d’électricité de Gravelines a eu des effets importants sur le développement du territoire considéré, notamment en termes d’impacts économiques et démographiques. Des synergies industrielles territoriales ont été rendues possibles notamment avec des industries électro-intensives installées à proximité ; la création d’un comité d’ancrage comme outil de gouvernance a confirmé l’implantation territoriale très forte de la centrale nucléaire au sein du territoire pour préparer et suivre les grands travaux à réaliser. C’est dans un souci constant d’anticipation des besoins en énergie du territoire qui s’inscrit dans une vision à long terme que nous portons une attention toute particulière au maintien d’une sécurité d’approvisionnement en énergie et à l’anticipation du démantèlement des outils de production et à leur renouvellement. Les questions relatives à l’information des populations et au rôle des différents acteurs restent un enjeu majeur.
