Concepciones de ?tica y valores de los estudiantes del grado 11 en dos intituciones educativas Alberto Santofimio Caicedo de Ibagu? y el colegio Colombo Ingl?s del Huila en Neiva

96 p. Recurso Electr?nicoEl presente trabajo investigativo se ocup? de la identificaci?n y an?lisis de los conceptos de ?tica y valores que tienen los estudiantes del grado once (11) de las instituciones educativas Alberto Santofimio Caicedo y El Colegio Colombo Ingl?s del Huila. De ah? que se aplicar?n dos encuestas, la primera para identificar los conceptos de los estudiantes frente a la ?tica y los valores, dise?ada bajo tres constructos te?ricos: ?tica grecorromana, ?tica moderna, ?tica contempor?nea y una segunda dise?ada por categor?as: Conciencia de Grupo Solidaridad y Bien Com?n (CGSBC), Conciencia de Legalidad (CL) y Conciencia de Compromiso y Responsabilidad (CCR) con el prop?sito de poder caracterizar sus conceptos. En consecuencia se logr? identificar que los estudiantes de las dos instituciones identifican el concepto de ?tica desde la l?nea de pensamiento filos?fico moderno y una caracterizaci?n de la ?tica en las tres categor?as (CGSBC, CL, CCR) tendiente a una frecuencia de decisi?n (siempre, casi siempre, pocas veces, nunca) como casi siempre. Aun as?, con los resultados y an?lisis obtenidos se evidencio que su teor?a y caracterizaci?n son contarios a la vivencia relacional de los estudiantes en su ambiente escolar. Por consiguiente se dise?aron dos momentos de formaci?n y recomendaciones basados en el referente te?rico de la presente investigaci?n, donde se propuso un acercamiento que considero el contexto hist?rico cultural de los educandos y su desarrollo moral evolutivo, que busco una formaci?n en ?tica y valores contempor?nea, pertinente y que a su vez contribuyera a los procesos de afrontamiento de las diferentes problem?ticas de convivencia escolar que afrontan estas dos instituciones. Para tales efectos esta investigaci?n implemento como metodolog?a: Investigaci?n acci?n, acompa?ado de un enfoque cualitativo y un dise?o transversal reflexivo. Por esta raz?n se consider? el contexto inmediato de los discentes en la elaboraci?n, aplicaci?n de instrumentos de recolecci?n de informaci?n y los momentos de formaci?n.The purpose of this research was to reflect slightly upon ethics and values concepts that eleventh graders have. The aim of this is to restate and foster a healthy living together among youngsters at school. Ethics and values concept were determined and characterised based on a selected theoretical foundation that underpinned this final paper. The type of research conducted on this experience was an Action Research project. Surveys and workshops of formation were designed and applied in every research stage. These workshops relied on theory to practice. The sample population was formed by ninety (90) pupils from Alberto Santofimio Caicedo and Colombo Ingles del Huila schools. From the results emerged that students had bias in ethics and values concepts and viewpoints. Students had an unclear vision of Ancient, Modern and Contemporary concepts in ethics and values. The formation workshops were designed and developed in order to talk about socio-critic and light ethics aiming at fostering student?s critical thinking towards situations in their living together where ethics and values should be practiced. Finally, some recommendations were given to each school, mainly in their ethics and values subjects as an improvement plan regarding to themes such as interpersonal relations, acceptance of limits, respect of other?s difference and dignity for the benefit of a healthy living together in their social surrounding. Key words: Ethics, values, concepts, characterization, school context, living together, action research, improvement plan, ethics and values study plan and recommendations

Bioelectronics-on-a-chip for cardio myoblast proliferation enhancement using electric field stimulation

Background: Cardio myoblast generation from conventional approaches is laborious and time-consuming. We present a bioelectronics on-a-chip for stimulating cells cardio myoblast proliferation during culture. Method: The bioelectronics chip fabrication methodology involves two different process. In the first step, an aluminum layer of 200 nm is deposited over a soda-lime glass substrate using physical vapor deposition and selectively removed using a Q-switched Nd:YVO4 laser to create the electric tracks. To perform the experiments, we developed a biochip composed of a cell culture chamber fabricated with polydimethylsiloxane (PDMS) with a glass coverslip or a cell culture dish placed over the electric circuit tracks. By using such a glass cover slip or cell culture dish we avoid any toxic reactions caused by electrodes in the culture or may be degraded by electrochemical reactions with the cell medium, which is crucial to determine the effective cell-device coupling. Results: The chip was used to study the effect of electric field stimulation of Rat ventricular cardiomyoblasts cells (H9c2). Results shows a remarkable increase in the number of H9c2 cells for the stimulated samples, where after 72 h the cell density double the cell density of control samples. Conclusions: Cell proliferation of Rat ventricular cardiomyoblasts cells (H9c2) using the bioelectronics-on-a-chip was enhanced upon the electrical stimulation. The dependence on the geometrical characteristics of the electric circuit on the peak value and homogeneity of the electric field generated are analyzed and proper parameters to ensure a homogeneous electric field at the cell culture chamber are obtained. It can also be observed a high dependence of the electric field on the geometry of the electrostimulator circuit tracks and envisage the potential applications on electrophysiology studies, monitoring and modulate cellular behavior through the application of electric fields

Adipokines and Inflammation: Focus on Cardiovascular Diseases

It is well established that adipose tissue, apart from its energy storage function, acts as an endocrine organ that produces and secretes a number of bioactive substances, including hormones commonly known as adipokines. Obesity is a major risk factor for the development of cardiovascular diseases, mainly due to a low grade of inflammation and the excessive fat accumulation produced in this state. The adipose tissue dysfunction in obesity leads to an aberrant release of adipokines, some of them with direct cardiovascular and inflammatory regulatory functions. Inflammation is a common link between obesity and cardiovascular diseases, so this review will summarise the role of the main adipokines implicated in the regulation of the inflammatory processes occurring under the scenario of cardiovascular diseases

Regularity Properties and Pathologies of Position-Space Renormalization-Group Transformations

We reconsider the conceptual foundations of the renormalization-group (RG) formalism, and prove some rigorous theorems on the regularity properties and possible pathologies of the RG map. Regarding regularity, we show that the RG map, defined on a suitable space of interactions (= formal Hamiltonians), is always single-valued and Lipschitz continuous on its domain of definition. This rules out a recently proposed scenario for the RG description of first-order phase transitions. On the pathological side, we make rigorous some arguments of Griffiths, Pearce and Israel, and prove in several cases that the renormalized measure is not a Gibbs measure for any reasonable interaction. This means that the RG map is ill-defined, and that the conventional RG description of first-order phase transitions is not universally valid. For decimation or Kadanoff transformations applied to the Ising model in dimension $d \ge 3$, these pathologies occur in a full neighborhood $\{ \beta > \beta_0 ,\, |h| < \epsilon(\beta) \}$ of the low-temperature part of the first-order phase-transition surface. For block-averaging transformations applied to the Ising model in dimension $d \ge 2$, the pathologies occur at low temperatures for arbitrary magnetic-field strength. Pathologies may also occur in the critical region for Ising models in dimension $d \ge 4$. We discuss in detail the distinction between Gibbsian and non-Gibbsian measures, and give a rather complete catalogue of the known examples. Finally, we discuss the heuristic and numerical evidence on RG pathologies in the light of our rigorous theorems.Comment: 273 pages including 14 figures, Postscript, See also ftp.scri.fsu.edu:hep-lat/papers/9210/9210032.ps.

Air quality and error quantity: pollution and performance in a high-skilled, quality-focused occupation

We provide the first evidence that short-term exposure to air pollution affects the work performance of a group of highly-skilled, quality-focused employees. We repeatedly observe the decision-making of individual professional baseball umpires, quasi-randomly assigned to varying air quality across time and space. Unique characteristics of this setting combined with high-frequency data disentangle effects of multiple pollutants and identify previously under-explored acute effects. We find a 1 ppm increase in 3-hour CO causes an 11.5% increase in the propensity of umpires to make incorrect calls and a 10 mg/m3 increase in 12-hour PM2.5 causes a 2.6% increase. We control carefully for a variety of potential confounders and results are supported by robustness and falsification checks

65 p. Recurso Electr?nicoLa motricidad fina ocupa un lugar importante en la educaci?n infantil, ya que es en la primera infancia que se genera una interdependencia en el desarrollo a nivel motor, intelectual y afectivo. La falta de esta habilidad en la etapa preescolar retrasa el proceso de aprendizaje. Por consiguiente se ha realizado este proyecto que cuenta con un conjunto de actividades integradoras, que permiten a los docentes aplicar nuevas estrategias que ayudan al desarrollo de la motricidad fina.Fine motor skills occupy an important place in early childhood education, since it is in early childhood that there is an interdependence in motor, intellectual and affective development. The lack of this skill in the preschool stage delays the learning process. Therefore, this project has been carried out with a set of integrating activities that allow teachers to apply new strategies that help the development of fine motor skills.
