Crítica de la psicoterapia integrativa

Esta investigación se realiza desde el paradigma de la complejidad del ser humano para reconocer las características del fenómeno psíquico, tales como la multicasualidad, no linealidad, el principio de contradicción entre lo uno y lo múltiple, los fenómenos de caoticidad, fractilidad, borrosidad, eventualidad y aleatoriedad que se encuentran presentes en la determinación del pisiquismo humano. En la segunda parte, se plantea una propuesta de integración que busca superar las condiciones epistemológicas que caracterizan a los intentos integrativos y las distintas teorías sobre el psiquismo, concibiendo al fenómeno psíquico como una propiedad emergente del ser humano, como un sistema de autorreferentes, que se autoconstruyen un sujeto determinado por el entorno social y que, al mismo tiempo contribuye a la construcción de ese entorno, gracias a los heterorreferentes que son configurados por la intersubjetividad

The HI Distribution Observed toward a Halo Region of the Milky Way

We use observations of the neutral atomic hydrogen (HI) 21-cm emission line to study the spatial distribution of the HI gas in a 80$\degree\times~$90$\degree$ region of the Galaxy halo. The HI column densities in the range of \mbox{3--11$\times$10$^{20}$ cm$^{-2}$} have been estimated for some of the studied regions. In our map---obtained with a spectral sensitivity of $\sim$2 K---we do not detect any HI 21-cm emission line {above 2$\sigma$} at Galactic latitudes higher than $\sim${46}$\degree$. {This report summarizes our contribution presented at the conference on the origin and evolution of barionic Galaxy halos}

Upper Limits to Magnetic Fields in the Outskirts of Galaxies

Based on CO(2-1) public data, we study the monoxide oxygen gas excitation conditions and the magnetic field strength of four spiral galaxies. For the galaxy outskirts, we found kinetic temperatures in the range of $\lesssim$35--38 K, CO column densities $\lesssim 10^{15}$--$10^{16}$ cm$^{-2}$, and H$_2$ masses $\lesssim 4\times 10^6$--$6\times10^8$ M$_\odot$. An H$_2$ density $\lesssim 10^3$ cm$^{-3}$ is suitable to explain the 2$\sigma$ upper limits of the CO(2-1) line intensity. We constrain the magnetic field strength for our sample of spiral galaxies and their outskirts by using their masses and H$_2$ densities to evaluate a simplified magneto-hydrodynamic equation. Our estimations provide values for the magnetic field strength on the order of $\lesssim$6--31 {\upmuG}

Shifts in leaf litter breakdown along a forest–pasture–urban gradient in Andean streams

Tropical montane ecosystems of the Andes are critically threatened by a rapid land-use change which can potentially affect stream variables, aquatic communities, and ecosystem processes such as leaf litter breakdown. However, these effects have not been sufficiently investigated in the Andean region and at high altitude locations in general. Here, we studied the influence of land use (forest–pasture–urban) on stream physico-chemical variables (e.g., water temperature, nutrient concentration, and pH), aquatic communities (macroinvertebrates and aquatic fungi) and leaf litter breakdown rates in Andean streams (southern Ecuador), and how variation in those stream physico-chemical variables affect macroinvertebrates and fungi related to leaf litter breakdown. We found that pH, water temperature, and nutrient concentration increased along the land-use gradient. Macroinvertebrate communities were significantly different between land uses. Shredder richness and abundance were lower in pasture than forest sites and totally absent in urban sites, and fungal richness and biomass were higher in forest sites than in pasture and urban sites. Leaf litter breakdown rates became slower as riparian land use changed from natural to anthropogenically disturbed conditions and were largely determined by pH, water temperature, phosphate concentration, fungal activity, and single species of leaf-shredding invertebrates. Our findings provide evidence that leaf litter breakdown in Andean streams is sensitive to riparian land-use change, with urban streams being the most affected. In addition, this study highlights the role of fungal biomass and shredder species (Phylloicus; Trichoptera and Anchytarsus; Coleoptera) on leaf litter breakdown in Andean streams and the contribution of aquatic fungi in supporting this ecosystem process when shredders are absent or present low abundance in streams affected by urbanization. Finally, we summarize important implications in terms of managing of native vegetation and riparian buffers to promote ecological integrity and functioning of tropical Andean stream ecosystems

Tendencias pedagógicas

Considero importante, para empezar, dar a conocer una definición general de la palabra pedagogía. Proviene de los vocablos griegos paidos (niño) y gogos (conducir); la pedagogía es la ciencia que se ocupa de la educación de los niños. Suena a algo muy simple y superficial, pero solo aparentemente, ya que si nos adentramos más, poco a poco veremos lo complejo y maravilloso que se torna el mundo de la pedagogía, dándonos cuenta de esto, e inmedia- tamente volviendo a la definición nos fijamos en la palabra educación

Proyecto creación de una empresa de organización de fiestas infantiles en la ciudad de Machala de la provincia de “El Oro”, 2010

The game is the most pleasant activity with which counts the human being, since he is born until he has reason use, the game has been and it is the axis that moves its expectations to look for a while of rest and enjoy. The games propitiate the activation of cognitive and motive mechanisms, by means of situations of exploration of the own corporal possibilities and of resolution of motive problems, it is in this stage to contribute to the majority acquisition of patron basic motors with those that new movement options can be built and to develop the motive capacities and the basic abilities correctly. For this context is important to emphasize that the study resides in the implementation of a company that offers a service of infantile parties organization, with good facilities and overalls originals for the children's entertainment that contribute to its development and personal and emotional growth amusement

Buhofónicos - en el medio

In this project, an EP with three unreleased songs of Buhofónicos was produced. In the pre-production phase of this phonogram, scores and arrangements of each song were written, musicians and technical team were chosen, and a real project costs budget was made. Afterwards, in the production phase, the project was recorded in three sessions at the CoM’s recording studio; it was also mixed and mastered under the concept of recreating a Buhofónicos’ live concert. Ultimately, the EP’s design was conceptualized; a launch and promotion strategy of the produced songs was generated for its insertion in the national and international alternative music business.En este proyecto se produjo un EP que contiene tres canciones inéditas de Buhofónicos. En la fase de pre-producción del fonograma se escribieron las partituras y arreglos de cada tema, se seleccionaron a los músicos y al equipo técnico de trabajo, y se realizó un presupuesto real de los costos del proyecto. Posteriormente, en la fase de producción se realizaron tres sesiones de grabación en el estudio de grabación del CoM, se mezcló y masterizó el proyecto bajo el concepto de recrear un concierto de Buhofónicos. En última instancia se conceptualizó el diseño del EP y se generó una estrategia de lanzamiento y promoción del material producido para su inserción en el medio musical alternativo nacional e internacional
