Evolution towards Smart Optical Networking: Where Artificial Intelligence (AI) meets the World of Photonics

Smart optical networks are the next evolution of programmable networking and programmable automation of optical networks, with human-in-the-loop network control and management. The paper discusses this evolution and the role of Artificial Intelligence (AI)

Continuous Improvement in Practice: One K–12 District’s Leadership Journey

K–12 leaders’ compliance mandates, challenges of adopting a continuous improvement approach to student success, and competing priorities often leave leaders feeling vulnerable and unprepared for the task. This basic qualitative study applied the continuous improvement framework (CIF) to research how improvement science penetrated an educational system. This basic qualitative study explored and described leaders’ commitment to employing the principles of improvement science at one California K–12 school district. An in-depth analysis of the interviewees’ transcriptions, persona, and experiences unveiled the following themes for continuous improvement: (a) transformational governance, (b) capacity building, (c) accountability, (d) limitations of transactional governance, and (e) outlier findings. Participants’ insights and experiences on the application of continuous improvement underscored the power of culture and affording leaders professional development to build their confidence and data literacy. The findings from this study could benefit K–12 leaders who wish to employ the principles of improvement as a system and everyday work

Pair correlation function of short-ranged square-well fluids

We have performed extensive Monte Carlo simulations in the canonical (NVT) ensemble of the pair correlation function for square-well fluids with well widths $\lambda-1$ ranging from 0.1 to 1.0, in units of the diameter $\sigma$ of the particles. For each one of these widths, several densities $\rho$ and temperatures $T$ in the ranges $0.1\leq\rho\sigma^3\leq 0.8$ and $T_c(\lambda)\lesssim T\lesssim 3T_c(\lambda)$, where $T_c(\lambda)$ is the critical temperature, have been considered. The simulation data are used to examine the performance of two analytical theories in predicting the structure of these fluids: the perturbation theory proposed by Tang and Lu [Y. Tang and B. C.-Y. Lu, J. Chem. Phys. {\bf 100}, 3079, 6665 (1994)] and the non-perturbative model proposed by two of us [S. B. Yuste and A. Santos, J. Chem. Phys. {\bf 101}, 2355 (1994)]. It is observed that both theories complement each other, as the latter theory works well for short ranges and/or moderate densities, while the former theory does for long ranges and high densities.Comment: 10 pages, 10 figure

Pedagogía universitaria y e-learning

Guía didáctica, curso 2015-2016, de la asignatura "Pedagogía universitaria y e-learning" del curso de Experto Universitario en Formación Online de la Universitat Politècnica de València

En pos de la educación activa

El objetivo de este informe es examinar la educación activa, a la que le corresponde un papel protagonista en la educación del siglo XXI. El incremento de la participación de los estudiantes en la vida universitaria, en todos sus ámbitos, es un asunto clave para el futuro universitario. Los principios que han definido el Espacio Europeo de Educación Superior (EEES) dejan claro que las personas son más importantes que los procedimientos, que el apoyo y la orientación en el aprendizaje son lo sustancial y que docencia universitaria e innovación educativa deben ir de la mano. La puesta en marcha del EEES se ha centrado en los cambios normativos y estructurales, pero el “día después” de Bolonia viene caracterizado por el cambio pedagógico en la universidad. Este análisis de la educación activa está estructurado en tres bloques. En el primero se resume lo que a lo largo de dos años se ha debatido en las cuatro jornadas organizadas por la Cátedra UNESCO. En el segundo se destaca la actualidad educativa a nivel global, fundamentalmente en cuanto a las propuestas impulsadas por las tecnologías digitales se refiere, que permiten al aprendiz ser responsable de su aprendizaje. Finalmente, en el tercer bloque se resume todo lo debatido y analizado, y se condensa en once principios que caracterizan la educación activa

Matemáticas a través de los cuentos en educación infantil

40 p. : il. -- Bibliogr.: pp. 32-33[ES] En el presente trabajo se pretende indagar sobre el valor didáctico del cuento como herramienta para enseñar conceptos matemáticos. Para ello se recopila y sintetiza información fundamentada relativa a la importancia de las matemáticas y la literatura infantil en las primeras edades. Seguidamente, a raíz de la matematización de un cuento, se expone el diseño y la puesta en práctica de una intervención que posteriormente se analiza. Para finalizar se extraen algunas conclusiones respecto a los objetivos propuestos inicialmente y a la puesta en práctica de la intervención, lo que da pie a comentar posibles líneas de continuación y de mejora.[EUS[] Lan honetan ipuinek Haur Hezkuntzako matematiken ikaskuntza eta irakaskuntzarako daukaten potentziala aztertu nahi da. Horretarako haur literaturaren eta haurrentzako matematiken inguruko hausnarketa teoriko bat egiten da. Ondoren, ipuin baten matematizazioan oinarritutako esku-hartzea deskribatzen eta aztertzen da. Azkenik, ondorioak aurkezten dira, lanaren helburuei zein esku-hartzeari berari dagozkienak. Konklusioon harira, lanari egin dakizkioken hobekuntzak ere aipatzen dira.[EN] The aim of this work is to investigate the didactic value of the story as a tool for teaching mathematics. Literature on mathematics and children's literature at early ages is reviewed. Next, an analysis is given of an intervention carried out using a mathematised story. Finally, some conclusions are drawn regarding the objectives and the implementation of the intervention. These conclusions suggest lines to be followed up for the development and improvement of this didactic implement

Hi Spin Temperatures and Heating Requirements in Outer Regions of Disk Galaxies

ABSRACT:We show how to use 21-cm emission and absorption studies to estimate the heat inputs to the neutral gas in low pressure environments, such as in outer disks of spiral galaxies, in galactic halos or in intergalactic space. For a range of model parameters we calculate the gas kinetic and spin temperatures ($T_K$ and $T_S$) and the relation between $T_S$ and the heat input to the gas. We outline the conditions for a ``two phase medium'' to exist. We find that although $T_S$ can be much smaller than $T_K$, $T_S$ is always $\gg 3$ K for column densities greater that $5 \times 10^{18}$ cm$^{-2}$. This excludes the possibility that relevant HI masses at the periphery of galaxies are invisible at 21-cm in emission. The outermost interstellar gas in a disk galaxy is more directly affected by external processes and in this paper we estimate the intensity of the extragalactic background at energies close to 0.1 keV by comparing our theoretical results with HI emission/absorption studies. We take into account the possibility that some energy produced in the inner regions affects the energy balance in outer regions. We find that in the absence of any other local heat source QSO dominated background models are still compatible with the spin temperature limits derived for the two best documented HI emission/absorption studies in outer regions.Comment: 24 pages, 8 figures ARCETRI-PR-93-2
