Post-Convergent Mediatization: Toward a Media Typology Beyond Web 2.0

In this article, I argue that the concept of convergence, as is still applied to media theory, has become an insufficient way for examining the current state and future of media phenomena. This is substantiated by the fact that digital media continue to exponentially percolate into human experience in ways that transcend mere integration.  I contend that a recognition of post-convergence as a theoretical realization is crucial to future developments in media theory because it presumes that digital media are progressing toward a “digitization of life” in ways that are envisioned within the very logic of digitality. As post-convergence continues its way to become a theoretical realization, media theory should begin posing its questions about the digital not in terms of how traditional media and its attributes prevail in the digital, but of how digitality as an objective reality engenders experiences of the real requiring approaches that can only be formulated from the logic of post-convergence.  From such theorization, I propose a working typology for conceptualizing the possible nature and direction of post-convergent media: hyper-mediation, bio-digitality, hyper-connection, and hyper-simulation

Examining the Impact of Innovation Forms on Sustainable Economic Performance: The Influence of Family Management

The aim of this research is to explore the effect that innovation, as a potential source of sustained competitive advantage and firm growth, has on the achievement of sustainable economic performance. In particular, this paper empirically examines the influence of four innovation forms (intramural R&D, extramural R&D, product innovation, and process innovation) on firms’ sustainable economic performance, considering the moderating effect of family involvement in management. To test the hypotheses, random-effects regression analyses are applied to a longitudinal sample of 598 Spanish private manufacturing firms throughout the 2006–2015 period. The results show a negative effect of intramural and extramural R&D on sustainable economic performance and a positive effect of process innovation on sustainable economic performance. Moreover, a reinforced relationship between process innovation and sustainable economic performance is also revealed when family involvement in management acts as a moderator. The findings make several contributions to research and practice

Mientras voy a clase: propuesta de intervención pedagógica para el desarrollo del pensamiento matemático de niños, niñas y jóvenes desescolarizados y pertenecientes a contextos socialmente vulnerables

Este trabajo tiene como finalidad mostrar una propuesta de intervención pedagógica para el desarrollo del pensamiento matemático en niños, niñas y jóvenes desescolarizados y pertenecientes a contextos socialmente vulnerables, que pretenden ingresar nuevamente al sistema educativo; a partir de la experiencia del proyecto la Escuela Busca al Niño!a, desarrollada en Medellín en el periodo 2005-2006. Además, esta se fundamenta en la teoría de las situaciones didácticas e identifica aquellos elementos esenciales que se deben tener presente al implementar estrategias de intervención para una población con las características mencionadas anteriormente

Alternative calculation of the physical mass of the p-meson

We have derived an expression for the physical mass and width of the ρ-meson in vacuum from its spectral function, calculated in the vector meson dominance model when a ρ 0 meson couples to two virtual pions π +–π −. The propagator is computed after evaluating the ρ-meson self-energy. The real part of the ρ-meson self-energy is given by a divergent integral and needs to be regularized; the regularization is done by using a double subtracted dispersion relation. The result leads to a closed analytical expression which allow us to evaluate the spectral function in a closed way. The physical mass, defined as the magnitude of the four-momentum |k| for which the spectral function S(k 2 ) attains its maximum value, is obtained, and it gives a value of 770 MeV, which is in total agreement with the reported experimental value of the ρ-meson mas

Optimal allocation of finite sampling capacity in accumulator models of multi-alternative decision making

When facing many options, we narrow down our focus to very few of them. Although behaviors like this can be a sign of heuristics, they can actually be optimal under limited cognitive resources. Here we study the problem of how to optimally allocate limited sampling time to multiple options, modelled as accumulators of noisy evidence, to determine the most profitable one. We show that the effective sampling capacity of an agent increases with both available time and the discriminability of the options, and optimal policies undergo a sharp transition as a function of it. For small capacity, it is best to allocate time evenly to exactly five options and to ignore all the others, regardless of the prior distribution of rewards. For large capacities, the optimal number of sampled accumulators grows sub-linearly, closely following a power law for a wide variety of priors. We find that allocating equal times to the sampled accumulators is better than using uneven time allocations. Our work highlights that multi-alternative decisions are endowed with breadth-depth tradeoffs, demonstrates how their optimal solutions depend on the amount of limited resources and the variability of the environment, and shows that narrowing down to a handful of options is always optimal for small capacities

La tensión entre el pensamiento informal y formal en la geometría mediante un modelo de geometría hiperbólica

En este trabajo, mostramos los avances de una investigación doctoral, en marcha, relacionada con la tensión existente entre la intuición del espacio físico y una geometría no euclidiana explorada mediante los modelos de geometría hiperbólica de Poincaré. Para documentar los aspectos que consideramos más importantes de dicha tensión, tomamos elementos conceptuales relacionados con: el modo de existencia de los entes matemáticos, las herramientas y su mediación, representaciones simbólicas y mecanismos de validación. Los resultados preliminares de la investigación, entre los que destacan la generalización de conceptos geométricos y la adecuada construcción de figuras geométricas hiperbólicas, surgen del desarrollo de actividades en los modelos de Poincaré implementadas con estudiantes de bachillerato. Estas actividades se enfocan en concepciones y mecanismos de validación en geometría, en un ambiente de papel y lápiz así como en uno de geometría dinámica. Aunque la investigación todavía no está concluida, podemos asegurar que el trabajo con los estudiantes revela lo que nos parece una joya cognitiva: lo que es coherente desde el punto de vista lógico, no necesariamente es aceptable para la intuición

Contribution to the knowledge of Portuguese serpentine flora: ecological characteristics, endemic plants, and implications for biodiversity conservation

Serpentine areas are scarce in the world, but contain a large number of endemic taxa. These areas have, in many cases, been little or not at all surveyed from a vegetation and biodiversity conservation point of view. The most important Portuguese serpentine outcrops are found in northeastern Portugal, particularly in the Bragança-Vinhais and Morais massifs. Here, we present a complete ecological-floristic check-list of serpentinophites that are found in these areas since this knowledge is essential for their evaluation, management and conservation. A total of 25 taxa, classified into three categories with different grades of serpentinophily, were included in the list: (1) obligate serpentinophytes (exclusively on serpentine), (2) endemic or widespread taxa that in Portugal occur exclusively in ultramafic outcrops, and (3) preferential serpentinophytes (most of the distribution range, at least 90% of populations, are found on serpentine). Genera common to other Iberian serpentine areas (Andalusian serpentine flora) are Odontarrhena, Arenaria, Armeria, Asplenium, Paragymnopteris, Saxifraga and Silene. The majority of the studied serpentinophytes (72%) occurred in endemic and highly specialized plant communities. About half of the studied serpentinophytes (48%) are assigned in some IUCN threat category. Consequently, it is necessary to implement conservation measures to guarantee the protection of these habitats.info:eu-repo/semantics/publishedVersio
