Autoevaluación del estudiante : ¿qué hemos aprendido y cuáles son los desafíos?
2015
Este artículo examina los principales temas que han sido una preocupación constante para los investigadores en el tema de la auto-evaluación de los alumnos en el mundo de habla inglesa. Estos incluyen si los estudiantes deben calificar su propio trabajo y si lo hacen adecuadamente, si hay bastantes precisión en la calificación y si la autoevaluación les empodera. Presentamos estos temas dentro de su contexto histórico, el análisis incluye los contextos y las creencias que motivaron su desarrollo. Los datos demuestran que la poca aceptación de autoevaluación está en contra de la investigación sobre la teoría y la práctica, la cual pone de relieve su importancia para apoyar el aprendizaje de…
Los tiempos de la violencia en Chile: La memoria obstinada de Patricio Guzmán
2009
Análisis del modo como La memoria obstinada de Patricio Guzmán, trataba de desbloquear la memoria social de la violencia construyendo un documental que hiciera dialogar el discurso de los supervivientes con elementos del archivo y con imágenes del pasado. Se expone cómo, a través de sutiles operaciones discursivas, el documental trata de traer al presente una experiencia de la represión que buena parte de la sociedad trataba de situar en el pasado.
Centrality and rapidity dependence of inclusive pion and prompt photon production in p+Pb collisions at the LHC with EPS09s nPDFs
2014
The centrality dependencies of the inclusive neutral pion and prompt photon nuclear modification factors for p+Pb collisions at the LHC are studied using a spatially dependent set of nuclear PDFs, EPS09s. The calculations are performed at mid- and forward rapidities searching for an observable which would optimally probe the spatial dependence of the nuclear PDFs. In addition, we discuss to which $x$ values of the nucleus the different observables are sensitive.
Image Segmentation by Deep Community Detection Approach
2017
International audience; To address the problem of segmenting an image into homogeneous communities this paper proposes an efficient algorithm to detect deep communities in the image by maximizing at each stage a new centrality measure, called the local Fiedler vector centrality (LFVC). This measure is associated with the sensitivity of algebraic connectivity to node removals. We show that a greedy node removal strategy, based on iterative maximization of LFVC, has bounded performance loss relative to the optimal, but intractable, combinatorial batch removal strategy. A remarkable feature of this method is the ability to segments the image automatically into homogeneous regions by maximizing…

Using PageRank for non-personalized default rankings in dynamic markets
2017
Abstract Default ranking algorithms are used to generate non-personalized product rankings for standard consumers, for example, on landing pages of online stores. Default rankings are created without any information about the consumers’ preferences. This paper proposes using the product centrality ranking algorithm (PCRA), which solves some problems of existing default ranking algorithms: Existing approaches either have low accuracy, because they rely on only one product attribute, or they are unable to estimate ranks for new or updated products, because they use past consumer behavior, such as previous sales or ratings. The PCRA uses the PageRank centrality of products in a product dominat…
"Table 1" of "J/psi suppression at forward rapidity in Au+Au collisions at sqrt(s_NN)=200 GeV"
2021
J/psi invariant yield in Au+Au collisions as a function of $N_{part}$ at forward rapidity ($p_{T}$ integrated). The statistical and systematic uncertainties vary point-to-point and are listed for each measured value. An additional global systematic uncertainty is provided in each column heading, which applies to all data points per column.

2021
J/psi nuclear modification $R_{AA}$ in Au+Au collisions as a function of $N_{part}$ at forward rapidity ($p_T$ integrated). The statistical and systematic uncertainties vary point-to-point and are listed for each measured value. An additional global systematic uncertainty is provided in each column heading, which applies to all data points per column.
The Centrality and Interpretation of Psalms in Judaism prior to and during Medieval Times: Approaches, Authorship, Genre, and Polemics
2020
Abstract This study discusses the centrality of the book of Psalms among the Jews and in Judaism. It outlines the seven most important and influential rabbinic exegetical works on Psalms, in the period before and during the medieval age: Targum Psalms and Midrash Psalms Shocher Tov, from some time in the Talmudic period; and five prominent medieval commentaries: Saadia Gaon, Moses haCohen ibn Gikatilla, Rashi, Abraham ibn Ezra, and David Kimchi. I briefly introduce each interpretative work and focus on selected aspects: The commentators’ distinct exegetical methods, their approaches to the questions of the authorship and genre of Psalms, and polemics with inside (e.g., Karaites) and outside…
