Exploration, exploitation and innovation performance: disentangling the evolution of industry

The evolution of industry has recently attracted the attention of scholars studying the relationships between exploration and exploitation strategies and innovation performance. Surprisingly, although extant research has already acknowledged its multidimensional character, it has only been analyzed in an aggregate fashion. In this paper, we distinguish two components of the evolution of industry, the pace of market evolution and the pace of technology evolution, and we elaborate on their different impacts in the context of exploration and exploitation strategies. More precisely, we argue that while a rapid pace of technology evolution has opposite impacts on the relationships between exploration (positive), exploitation (negative) and innovation performance, a rapid pace of market evolution positively affects both exploration and exploitation. Our findings provide substantial support for our prediction using a large panel of Spanish innovating firms for the period 2008–2012

Reflections on an educational program on moral and civic virtues and values in secondary schools. A case study in Mexico.

The research we present is part of the project Researching and Promoting Character Education in Latin American Secondary Schools funded by the Templeton World Charity Foundation.In this research work we present a case study, focusing on the values program implemented in a Mexican public school in the central area of the country. Our exploration of the capacity of the school when implementing the values program is based on the analysis of documents provided by the school which are related with the project, semi-structured interviews, in-depth interviews, images and the participatory observation carried out in the school over a period of three weeks. The wealth of informants (principals, teachers, pupils and parents) allowed us to gather a broader variety of information on the reality of the values program applied

An exploratory Delphy study on Character Education in Latin-American countries: Argentina, Colombia and Mexico

En el proyecto Researching and Promoting Character Education in Latin American Secondary Schools, financiado por la Templeton World Charity Foundation, nos aproximamos a la percepción que de la Educación del Carácter se tiene en Argentina, Colombia y México. La Educación del Carácter integra las propuestas para promover la ciudadanía. Para el inicio de esta investigación elaboramos un estudio piloto basándonos en la metodología Dephi, con el objetivo de discernir cuáles son los temas más candentes alrededor de la Educación del Carácter en estos países. Esta metodología -rigurosa y de fácil manejo- permite la obtención de un conocimiento en profundidad sobre la problemática de la Educación del Carácter. Contamos con la participación de diferentes expertos del ámbito académico, escolar y administrativo. Durante el proceso realizamos tres interacciones con los expertos para alcanzar un mayor consenso en sus opiniones. Para ello aplicamos dos rondas de preguntas cerradas y abiertas con las que obtener una mayor riqueza y convergencia en los datos obtenidos. Como resultado constatamos que la Educación del Carácter no es un término habitual en el ámbito educativo de estos países. Además, en este tipo de educación incide la influencia y relación entre los agentes y el currículum explícito-oculto en la escuela

Questions and answers regarding character education in Latin-American countries (Mexico, Colombia and Argentina). An exploratory Delphi study.

Abstract: In the project Researching and Promoting Character Education in Latin Ameri-can Secondary Schools funded by the Templeton World Charity Foundation,we address how Character Education is perceived in three Latin-American countries (Argentina, Colom-bia and Mexico). To carry out this research we produced a pilot study based on the Delphi method, in order to find the most relevant issues regarding the subject of Character Educa-tion in those Countries. This methodology offers us a rigorous and easily managed means of obtaining in-depth knowledge of the current problems of Character Education. For the Delphi study, we relied on the participation of various experts from the academic, school and administrative areas. During the process, we carried out three sessions with the experts in order to reach the highest possible consensus. Thus, we used two rounds of closed and open questions to obtain a good perspective of the situation. The result confirmed that Character Education is not a common term in the world of education in these countries. Moreover, this type of education is affected by the influence and relationship between the actors and the explicit-hidden curricula.En el proyecto Researching and Promoting Character Education in Latin American Secondary Schools, financiado por la Templeton World Charity Foundation, nos aproximamos a la percepción que de la Educación del Carácter se tiene en Argentina, Colombia y México.

Gravitational anomalies signaling the breakdown of classical gravity

Recent observations for three types of astrophysical systems severely challenge the GR plus dark matter scenario, showing a phenomenology which is what modified gravity theories predict. Stellar kinematics in the outskirts of globular clusters show the appearance of MOND type dynamics on crossing the $a_{0}$ threshold. Analysis shows a ``Tully-Fisher'' relation in these systems, a scaling of dispersion velocities with the fourth root of their masses. Secondly, an anomaly has been found at the unexpected scales of wide binaries in the solar neighbourhood. Binary orbital velocities cease to fall along Keplerian expectations, and settle at a constant value, exactly on crossing the $a_{0}$ threshold. Finally, the inferred infall velocity of the bullet cluster is inconsistent with the standard cosmological scenario, where much smaller limit encounter velocities appear. This stems from the escape velocity limit present in standard gravity; the ``bullet'' should not hit the ``target'' at more than the escape velocity of the joint system, as it very clearly did. These results are consistent with extended gravity, but would require rather contrived explanations under GR, each. Thus, observations now put us in a situation where modifications to gravity at low acceleration scales cease to be a matter of choice, to now become inevitable.Comment: 10 pages, 5 figures, Astrophysics and Space Science Proceedings 38, 4

El declive de la educación del carácter en Estados Unidos durante el siglo XX

El objetivo de este estudio es reflexionar sobre cinco factores que influyeron en el declive de la educación del carácter en Estados Unidos durante el siglo XX, con el ánimo de entender mejor la compleja situación actual de este enfoque educativo: 1) una relación mal entendida con el ámbito religioso que la excluye de la educación pública laica; 2) los paradigmas sociales del progreso y de la fragilidad de la infancia que contribuyen a desestimarla o considerarla inconveniente; 3) concebirla como mero adiestramiento en el que no se considera el desarrollo moral racional; 4) el relativismo moral; y, por último, 5) las críticas de la Psicología. Para finalizar, se ofrecen unas reflexiones que incluyen diversos testimonios recientes a favor de la educación del carácter y se sugiere la necesidad de integrar este ámbito en los sistemas educativos para enfrentar los retos morales y sociales del siglo XXI.The aim of this study is to reflect on five factors that influenced the decline of character education in the United States during the 20th century, in order to gain a deeper understanding of the current complex situation of this educational field: 1) a misunderstood relationship with the religious sphere that excludes it from public secular education; 2) the social paradigms of progress and childhood fragility that contribute to reject it, or consider it inconvenient; 3) conceiving it as mere training in which rational moral development is not considered; 4) moral relativism; and, finally, 5) the criticisms of Psychology. At last, several recent testimonies in favor of character education are included. Our final reflections suggest the need to integrate this area into education systems to face the moral and social challenges of the 21st century

Wide binaries as a critical test of Classical Gravity

Modified gravity scenarios where a change of regime appears at acceleration scales $a<a_{0}$ have been proposed. Since for $1 M_{\odot}$ systems the acceleration drops below $a_{0}$ at scales of around 7000 AU, a statistical survey of wide binaries with relative velocities and separations reaching $10^{4}$ AU and beyond should prove useful to the above debate. We apply the proposed test to the best currently available data. Results show a constant upper limit to the relative velocities in wide binaries which is independent of separation for over three orders of magnitude, in analogy with galactic flat rotation curves in the same $a<a_{0}$ acceleration regime. Our results are suggestive of a breakdown of Kepler's third law beyond $a \approx a_{0}$ scales, in accordance with generic predictions of modified gravity theories designed not to require any dark matter at galactic scales and beyond.Comment: accepted for publication in EPJ

Enhanced stability of perovskite solar cells incorporating dopant-free Crystalline spiro-OMeTAD layers by vacuum sublimation

The main handicap still hindering the eventual exploitation of organometal halide perovskite-based solar cells is their poor stability under prolonged illumination, ambient conditions, and increased temperatures. This article shows for the first time the vacuum processing of the most widely used solid-state hole conductor (SSHC), i.e., the Spiro-OMeTAD [2,2′,7,7′-tetrakis (N,N-di-p-methoxyphenyl-amine) 9,9′-spirobifluorene], and how its dopant-free crystalline formation unprecedently improves perovskite solar cell (PSC) stability under continuous illumination by about two orders of magnitude with respect to the solution-processed reference and after annealing in air up to 200 °C. It is demonstrated that the control over the temperature of the samples during the vacuum deposition enhances the crystallinity of the SSHC, obtaining a preferential orientation along the π–π stacking direction. These results may represent a milestone toward the full vacuum processing of hybrid organic halide PSCs as well as light-emitting diodes, with promising impacts on the development of durable devices. The microstructure, purity, and crystallinity of the vacuum sublimated Spiro-OMeTAD layers are fully elucidated by applying an unparalleled set of complementary characterization techniques, including scanning electron microscopy, X-ray diffraction, grazing-incidence small-angle X-ray scattering and grazing-incidence wide-angle X-ray scattering, X-ray photoelectron spectroscopy, and Rutherford backscattering spectroscopy.The authors thank the “Agencia Estatal de Investigación”, “Consejería de Economía y Conocimiento de la Junta de Andalucía” (US‐1263142), “Ministerio de Economía y Competitividad” (MAT2016‐79866‐R, MAT2013‐42900‐P, FPA2016‐77689‐C2‐1‐R, and MAT2016‐76892‐C3‐2‐R) and the European Union (EU) through cohesion fund and FEDER 2014‐2020 programs for financial support.

Galactic-Centre Gamma Rays in CMSSM Dark Matter Scenarios

We study the production of gamma rays via LSP annihilations in the core of the Galaxy as a possible experimental signature of the constrained minimal supersymmetric extension of the Standard Model (CMSSM), in which supersymmetry-breaking parameters are assumed to be universal at the GUT scale, assuming also that the LSP is the lightest neutralino chi. The part of the CMSSM parameter space that is compatible with the measured astrophysical density of cold dark matter is known to include a stau_1 - chi coannihilation strip, a focus-point strip where chi has an enhanced Higgsino component, and a funnel at large tanb where the annihilation rate is enhanced by the poles of nearby heavy MSSM Higgs bosons, A/H. We calculate the total annihilation rates, the fractions of annihilations into different Standard Model final states and the resulting fluxes of gamma rays for CMSSM scenarios along these strips. We observe that typical annihilation rates are much smaller in the coannihilation strip for tanb = 10 than along the focus-point strip or for tanb = 55, and that the annihilation branching ratios differ greatly between the different dark matter strips. Whereas the current Fermi-LAT data are not sensitive to any of the CMSSM scenarios studied, and the calculated gamma-ray fluxes are probably unobservably low along the coannihilation strip for tanb = 10, we find that substantial portions of the focus-point strips and rapid-annihilation funnel regions could be pressured by several more years of Fermi-LAT data, if understanding of the astrophysical background and/or systematic uncertainties can be improved in parallel.Comment: 33 pages, 12 figures, comments and references added, version to appear in JCA
