Analysis of the agri-food chain of coconut (cocos nucifera) in the province of Manabí, Ecuador Resumen El sector cocotero representa uno de los sectores agrícolas que ayuda a sostener la economía de la provincia de Manabí, sin embargo, presenta debilidades en su gestión productiva y de comercialización, además de ausencia de datos en su manejo alrededor de Manabí. El objetivo del presente estudio es caracterizar la cadena agroalimentaria de coco en Manabí, mediante la identificación de los actores y las debilidades del sector, a través de entrevistas y el mapeo de la cadena. Los resultados detallan que existen seis eslabones, treinta y cuatro productores, treinta y nueve comerciantes mayoristas y distribuidores, diez fabricantes (transformadores) y setenta y siete vendedores. El aporte de esta investigación es social y práctica, debido a que se enfoca en generar información sobre una cadena poco analizada en la provincia, y en donde se sitúan gran parte de la población vulnerable de la zona. Palabras clave: Gestión productiva; integración; cadena agroalimentaria, coco, desarrollo y sostenibilidad. Abstract The coconut sector represents one of the agricultural sectors that helps to sustain the economy of the province of Manabí, however, it presents weaknesses in its production and marketing management, in addition to the absence of data on its management around Manabí. The objective of this study is to characterize the coconut agri-food chain in Manabí, by identifying the actors and the weaknesses of the sector, through interviews and mapping the chain. The results detail that there are six links, thirty-four producers, thirty-nine wholesalers and distributors, ten manufacturers (transformers) and seventy-seven sellers. The contribution of this research is social and practical, because it focuses on generating information about a chain that is little analyzed in the province, and where a large part of the vulnerable population of the area is located. Keywords: Productive management; integration; agri-food chain, coconut, development and sustainability.

En este trabajo se aborda la temática del abuso sexual a niños, niñas y adolescentes y la importancia de la orientación familiar en la prevención de este abominable mal que azota con gran fuerza a una población vulnerable de la sociedad. Comprende un análisis de datos históricos de los orígenes de esta práctica hasta la incidencia de casos que en la actualidad se revelan en la realidad ecuatoriana, sobre todo. Se reflexiona sobre el preocupante aumento de casos que salen a la luz pública, así como también aquellos que no son expuestos y que son parte de una estadística oculta, pero que constituyen una realidad latente que urge ser tratada. Actualmente en un alto índice de familias es muy escaso el diálogo sobre temas de prevención de la violencia sexual infantojuvenil, en gran medida por tabúes, temores e idiosincrasias culturales y falta de capacitación, por lo que se concluye que, a partir de una mayor intervención a través de procesos técnicos, la orientación familiar podría ser un proceso clave para disminuir esta abominable práctica social. PALABRAS CLAVE: Orientación familiar; abuso sexual; violación; población vulnerable. THE FAMILY ORIENTATION IN THE PREVENTION OF SEXUAL ABUSE TO CHILDREN AND ADOLESCENTS ABSTRACT This paper addresses the issue of sexual abuse of children and adolescents and the importance of family guidance in the prevention of this abominable evil that strikes with great force a vulnerable population of society. It includes an analysis of historical data on the origins of this practice up to the incidence of cases that are currently revealed in the Ecuadorian reality, above all. It reflects on the worrying increase of cases that come to public light, as well as those that are not exposed and that are part of a hidden statistic, but that constitute a latent reality that urgently needs to be addressed. At present, in a high index of families, there is very little dialogue about prevention of sexual violence against children and adolescents, largely due to taboos, fears and cultural idiosyncrasies and lack of training, so it is concluded that, after a greater intervention Through technical processes, family counseling could be a key process to reduce this abominable social practice.

Abstract: I argue that authentic photography is not able to develop to the full as a communicative representational art. Photography is authentic when it is true to its self-image as the imprinting of images. For an image to be imprinted is for its content to be linked to the scene in which it originates by a chain of sufficient, mind-independent causes. Communicative representational art (in any medium: photography, painting, literature, music, etc.) is art that exploits the resources of representation to achieve artistically interesting communication of thought. The central resources of representation are content, vehicle properties, and the interplay between these two. Whereas painting and other representational arts are able to exploit all three to communicate thought, authentic photography can exploit interplay only to a very limited degree. However, the exploitation of interplay is the culmination of communicative representational art: the natural endpoint in its development.   Keywords: aesthetics, philosophy of art, photography, painting   Resumen: sostengo que la fotografía genuina no puede desarrollarse al máximo como un arte representacional comunicativo. La fotografía es genuina cuando es fiel a su propia imagen como de impresión imágenes.

Un arte representacional comunicativo (en cualquier medio: fotografía, pintura, literatura, música, etc.) es un arte que explota los recursos de la representación para lograr la comunicación de un pensamiento de forma artísticamente interesante.

Mientras que la pintura y otras artes representacionales son capaces de explotar los tres para comunicar un pensamiento, la fotografía genuina puede explotar esa interacción solo en un grado muy limitado.

Aprendizaje Cooperativo

La presente investigación se la realizó debido a la importancia que implica la calidad de educación que se imparta a los estudiantes en el aula de clases y se cumplan los objetivos que en un principio fueron establecidos por los docentes. Hay que estar conscientes de que, el proceso educativo es una cadena de propuestas objetivas que deben cumplir en un orden secuencial hasta cumplir su objetivo final que es la formación académica de un ser humano listo para enfrentar, cumplir nuevos retos y metas. El aprendizaje cooperativo constituye una de las metodologías alternativas de gran importancia en el proceso de interaprendizaje que permite desarrollar habilidades y destrezas grupales que promuevan la motivación del estudiante. En este sentido se pudo determinar la incidencia del trabajo cooperativo en el interaprendizaje de los estudiantes en la asignatura de Química en la Unidad Educativa fiscal “José Leónidas Delgado” mediante la aplicación de los métodos descriptivos y propositivos, fortaleciendo el aprendizaje de manera colectiva, generando mayor motivación y el deseo de aprender de manera cooperativa. PALABRAS CLAVE: Metodología; colaboración; motivación; innovación. Cooperative work and inter-learning in Chemistry students of the first year of high school ABSTRACT This research was carried out due to the importance of the quality of education given to students in the classroom and the objectives that were initially established by teachers are met. We must be aware that the educational process is a chain of objective proposals that must be met in a sequential order until they reach their final objective, which is the academic formation of a human being ready to face, meet new challenges and goals. Cooperative learning is one of the alternative methodologies of great importance in the inter-learning process that allows developing group skills and abilities that promote student motivation. In this sense, it was possible to determine the incidence of cooperative work in the inter-learning of students in the subject of chemistry in the Fiscal Education Unit "José Leónidas Delgado", through the application of descriptive and propositive methods, strengthening learning collectively, generating greater motivation and the desire to learn cooperatively.

It is interesting to observe polymers at atomic size resolution. Some works have been reported for thorium pyromellitate by using a STEM (1), or a CTEM (2,3). The results showed that this polymer forms a chain in which thorium atoms are arranged. However, the distance between adjacent thorium atoms varies over a wide range (0.4-1.3nm) according to the different authors.The present authors have also observed thorium pyromellitate specimens by means of a field emission STEM, described in reference 4. The specimen was prepared by placing a drop of thorium pyromellitate in 10-3 CH3OH solution onto an amorphous carbon film about 2nm thick. The dark field image is shown in Fig. 1A. Thorium atoms are clearly observed as regular atom rows having a spacing of 0.85nm. This lattice gradually deteriorated by successive observations. The image changed to granular structures, as shown in Fig. 1B, which was taken after four scanning frames.

Microtubules form part of the cytoskeleton of eukaryotic cells. They are hollow libers of about 25 nm diameter made up of 13 protofilaments, each of which consists of a chain of heterodimers of α-and β-tubulin. Microtubules can be assembled in vitro at 37°C in the presence of GTP which is hydrolyzed during the reaction, and they are disassembled at 4°C. In contrast to most other polymers microtubules show the behavior of “dynamic instability”, i.e. they can switch between phases of growth and phases of shrinkage, even at an overall steady state [1]. In certain conditions an entire solution can be synchronized, leading to autonomous oscillations in the degree of assembly which can be observed by X-ray scattering (Fig. 1), light scattering, or electron microscopy [2-5]. In addition such solutions are capable of generating spontaneous spatial patterns [6].In an earlier study we have analyzed the structure of microtubules and their cold-induced disassembly by cryo-EM [7]. One result was that disassembly takes place by loss of protofilament fragments (tubulin oligomers) which fray apart at the microtubule ends. We also looked at microtubule oscillations by time-resolved X-ray scattering and proposed a reaction scheme [4] which involves a cyclic interconversion of tubulin, microtubules, and oligomers (Fig. 2). The present study was undertaken to answer two questions: (a) What is the nature of the oscillations as seen by time-resolved cryo-EM? (b) Do microtubules disassemble by fraying protofilament fragments during oscillations at 37°C?

Processing Mechanisms

Abstract Most cognitive psychophysiological studies assume (1) that there is a chain of (partially overlapping) cognitive processes (processing stages, mechanisms, operators) leading from stimulus to response, and (2) that components of event-related brain potentials (ERPs) may be regarded as manifestations of these processing stages. What is usually discussed is which particular processing mechanisms are related to some particular component, but not whether such a relationship exists at all. Alternatively, from the point of view of noncognitive (e. g., “naturalistic”) theories of perception ERP components might be conceived of as correlates of extraction of the information from the experimental environment. In a series of experiments, the author attempted to separate these two accounts, i. e., internal variables like mental operations or cognitive parameters versus external variables like information content of stimulation. Whenever this separation could be performed, the latter factor proved to significantly affect ERP amplitudes, whereas the former did not. These data indicate that ERPs cannot be unequivocally linked to processing mechanisms postulated by cognitive models of perception. Therefore, they cannot be regarded as support for these models.

Hemisphere Specialization

Previous studies often revealed a right-hemisphere specialization for processing the global level of compound visual stimuli. Here we explore whether a similar specialization exists for the detection of intersected contours defined by a chain of local elements. Subjects were presented with arrays of randomly oriented Gabor patches that could contain a global path of collinearly arranged elements in the left or in the right visual hemifield. As expected, the detection accuracy was higher for contours presented to the left visual field/right hemisphere. This difference was absent in two control conditions where the smoothness of the contour was decreased. The results demonstrate that the contour detection, often considered to be driven by lateral coactivation in primary visual cortex, relies on higher-level visual representations that differ between the hemispheres. Furthermore, because contour and non-contour stimuli had the same spatial frequency spectra, the results challenge the view that the right-hemisphere advantage in global processing depends on a specialization for processing low spatial frequencies.
