La Cuarta Revolución Industrial o su cuasi-sinónimo Tecnología 4.0 es un constructo útil para analizar una etapa de desarrollo, en curso, de las tecnologías avanzadas y su relación con la sociedad. Presentamos una breve descripción de los retos para los países de América Latina en su aplicación en la Administración Pública y en su gobernanza. El go...
Abstract The Computational Chemistry List is a mailing list, portal, and community which brings together people interested in computational chemistry, mostly practitioners. It was formed in 1991 and continues to exist as a vibrant discussion space, highly valued by its members, and serving both its original and new functions. Its duration has been...

span>Para evitar los problemas de significado propios de palabras polisémicas y empezar a acotar este escrito en congruencia con su titulo, diré que la calidad es un juicio que se establece cuando un producto cubre ciertas especificaciones que se consideran valiosas en cierto sentido.</span
This work presents a summary of the debates about Network Neutrality in the legislative process of Mexico in 2013–2014. A major telecommunications law and market reform is taking place in the country and Network Neutrality is a useful test case to measure how convergent the legislation actually manages to be and to identify options that can be tran...
p>Discuto los argumentos a favor de introducir el aprendizaje de la programación de computadoras en el bachillerato, así como algunos en contra; además, propongo una vía de acción de carácter general.</p
Innovar exige compartir. Para ello debemos transformar la administración de la propiedad intelectual. Acceso abierto y otras opciones. Análisis, propuestas y ejemplos.
Innovation requires sharing. To do that, we must transform intellectual property management. Open access and other options. Analysis, proposals and examples.
This paper reports research on the empowerment of Internet governance actors from developing countries, BRICS and the European Union, with emphasis on the first, relative to the US. The main findings are that non-governmental actors find particularly strong empowerment in the multistakeholder arrangements, compared to alternatives such as multilate...
An original approach to Network Neutrality is presented. Violations to Network Neutrality are considered as risk and a risk management framework to deal with such violations is presented. This framework can be used by different parties in varied environments for dealing with preventive as well as reactive action in the face of violations by Interne...
El proyecto �m-learning en Ciencia� fue planteado por los autores para proveer un modelo anticipado de lo que puede ser el �aprendizaje móvil� o �m-learning� con dispositivos móviles de alta capacidad de cómputo, comunicación y representación rica de la realidad. Para ello se utilizaron computadoras portátiles, dispositivos de posicionamiento geoes...
Presentación del Monográfico "WEB 2.0: DISPOSITIVOS MÓVILES Y ABIERTOS PARA EL APRENDIZAJE" coordinado por Alejandro Pisanty
Professor Lorenzo García Aretio’s book is a pleasure to read in Spanish. Lorenzo is, among other things, the UNESCO Chair for Distance Education and a superb conversationalist. The joy of hearing his voice is certainly evident when reading this book. His merry, bubbly chat is converted to formal and precise writing, in which paragraphs containing h...
The quantitative structure-activity relationships (QSAR) of all known competitive inhibitors of the enzyme phosphoenolpyruvate carboxylase from C4 plants were investigated by means of molecular mechanics, the semiempirical quantum chemical methods MNDO and AM1, and the Hansch approach. In the case of phosphoenolpyruvate analogues, the hydrophobicit...
This paper offers a simple example for calculation of band structures that was tested by graduate students and advanced undergraduates. Keywords (Audience): Upper-Division Undergraduate
Self-consistent LSDF potentials resulting from LMTO calculations are used to start embedded-cluster calculations of electronic structure of ordered and moderately disordered solids in a Lloyd multiple-scattering formalism, This is done as a shortcut to remedy the difficulties of attaining full self-consistency in this approach. We report results ob...
The interaction between atomic and magnetic order is very strong in Ni-Pt alloys, whereas Co-Pt alloys show local magnetic properties which are independent of the composition and state of order of the system. A multiple-scattering calculation on Ni-Pt alloys is used in this paper, together with band structures for ordered compounds of both Ni-Pt an...
The results of self-consistent, spin-polarized LMTO band structure calculations are shown for the compounds Ni3Pt and NiPt3, ofL12 (Cu3Au) structure. Lattice constants are reported together with bulk moduli, and the electronic structure is studied in relation to magnetism in both cubic compounds. Covalent magnetism is shown to act against the magne...
Calculation of the DOS (Density of States) for the three monohydrides of V Nb and Ta in the orthorhombic β-phase were performed using the LMTO method. In all three systems the hydrogen induced states below the Fermi level split into two maxima as a consequence of the H-H interactions. This fact agrees with photoemission experiments. We report also...
A novel analysis is presented for the electronic structure of UTe, pointing out the important contributions of uranium p and d states as well as tellurium d states not previously studied. Also found is the f-band splitting. Full analysis for both electron spins brings out uranium-f to tellurium-d bonding and shows peculiar d-electron features only...
The multiple scattering cluster method is used to calculate densities of states for Cu, Ag, and Au. The results compare favorably with experimental photoemission spectra. The method converges rapidly with the cluster size used for the calculation.
México El tema de la Sociedad de la Información es relevante en la medida en que sus productos están proveyéndonos de medios para superar positivamente el retraso económico, la pobreza, las enfermedades y el hambre en nuestro país, influyen de una manera armónica en las políticas públicas y en la acción libre de la sociedad civil, cada vez más impo...
Ensayo Este texto tiene como objetivo describir la relación entre la marginación digital y educación, y se formulan algunas propuestas de acción para enfrentar la marginación digital desde la educación en México. p.115-163
