No full textAnaliza las características emocionales y capacidades comunicacionales de alumnos promotores del Acoso Escolar. La investigación con enfoque cuantitativo se realizó en la Escuela Oficial Mixta No. 608 “Hilda Alicia González Aparicio de Falla”, ubicada en la zona 16 de la ciudad capital. Para seleccionar la muestra se utilizó la técnica por conveniencia y estuvo conformada por 15 alumnas de nivel primario. La recopilación de datos se realizó por medio de las siguientes técnicas: evaluación y observación. Los instrumentos que se utilizaron fueron: test estilos de comunicación, test Otis, diario de campo y planificación de talleres. Analiza e interpreta los resultados y concluye que, las alumnas presentaron características emocionales comúnmente, se reflejaron en casos de maltrato infantil causando por conductas inadecuadas tanto con sus compañeros como con las autoridades. Así mismo, se observó déficit en las capacidades comunicacionales. Recomienda, brindar un ambiente rodeado de respeto, comprensión, paciencia y amor con el propósito de estabilizar emocional y moralmente al menor, así como fomentar en los padres de familia las adecuadas normas de educación a poner en práctica en el hogar

Analiza e interpreta resultados y concluye que la muestra presenta en su mayoría componentes de prácticas adecuadas de comunicación entre padres e hijos, lo que no coincide con la conducta agresiva que las docentes refiere
Range Unit Root (RUR) Tests: Robust against Nonlinearities, Error Distributions, Structural Breaks and Outliers
No full textSince the seminal paper by Dickey and Fuller in 1979, unit-root tests have conditioned the standard approaches to analysing time series with strong serial dependence in mean behaviour, the focus being placed on the detection of eventual unit roots in an autoregressive model fitted to the series. In this paper, we propose a completely different method to test for the type of long-wave patterns observed not only in unit-root time series but also in series following more complex data-generating mechanisms. To this end, our testing device analyses the unit-root persistence exhibited by the data while imposing very few constraints on the generating mechanism. We call our device the range unit-root (RUR) test since it is constructed from the running ranges of the series from which we derive its limit distribution. These nonparametric statistics endow the test with a number of desirable properties, the invariance to monotonic transformations of the series and the robustness to the presence of important parameter shifts. Moreover, the RUR test outperforms the power of standard unit-root tests on near-unit-root stationary time series; it is invariant with respect to the innovations distribution and asymptotically immune to noise. An extension of the RUR test, called the forward?backward range unit-root (FB-RUR) improves the check in the presence of additive outliers. Finally, we illustrate the performances of both range tests and their discrepancies with the Dickey?Fuller unit-root test on exchange rate series.Publicad
Professional Mobility and “Objective” and “Subjective” Satisfaction. a Non- Linear Analysis from the Theory of the Three-Dimensional Spiral of Sense in Population of Doctors
No full textThis work goes along the lines of the author’s research (1995-2016) on professional careers and models bearing causes and effects regarding sustained interaction (core, psychosocial, institutional and structural factors). The aim of this paper was analyze, through the doctors’ social representations, the levels of satisfaction evidenced by those who have advanced professionally to the highest positions within the scientific (or other) system. The hypothesis states that the relation is not linear but inverse. Satisfaction would not increase according to the Professional Status. We consider here, on the one hand, the insufficient Professionalization and the increasing demands from the market; and on the other, the impact structural limits have on the micro level. The methodology used was quanti-qualitative (semi-structured questionnaires, interviews, and hierarchical evocations). The population consisted of doctors (2005-2012) from the National University of Cuyo, in Argentina and the Cnam (France) of different courses of study. The results confirm the hypothesis. As regards what was observed among those who advanced professionally, the increase on the growing market demands along with the lack of institutionalized means in order to reach goals, result in lower satisfaction. This is interpreted from the theory of the author, which involves 3 levels (macro-meso-micro-macro) (Aparicio, 2015 a, b). We also consider the theories of anomie and of the expectancy of valence (Feather - Davenport). Findings along this line were also seen in studies with scientists (Aparicio, 2014). The results propose a revision in the prevailing working conditions and police: satisfaction acts on subsystems and consolidates them.Fil: Aparicio, Miriam Teresita. Universidad Nacional de Cuyo.

Diphotons from diaxions
No full textAbstract: We study models in which the 750 GeV diphoton excess is due to a scalar decaying to two pseudo-Nambu-Goldstone bosons that subsequently decay into two pairs of highly boosted photons, misidentified as individual photons. Performing a model independent analysis we find that, with axion mass around 200 MeV, this class of theories can naturally explain the observed signal with a large width, without violating monojet constraints. At the same time the requirement of a prompt axion decay can be satisfied only with a relatively large axion-photon coupling, leading to many new charged particles at the TeV scale. However, the required multiplicities of such fields is still moderately reduced relative to models with direct diphoton production. © 2016, The Author(s)
