The Effect of Increasing Dialysate Magnesium on Serum Calcification Propensity in Subjects with End Stage Kidney Disease
Authors: Bressendorff Iain , Hansen Ditte , Schou Morten , Pasch Andreas , Brandi Lisbet
Published: August 2018

Background and objectives

Serum calcification propensity is a novel functional test that quantifies the functionality of the humeral system of calcification control. Serum calcification propensity is measured by T50, the time taken to convert from primary to secondary calciprotein particle in the serum. Lower T50 represents higher calcification propensity and is associated with higher risk of cardiovascular events and death in patients with ESKD. Increasing magnesium in serum increases T50, but so far, no clinical trials have investigated whether increasing serum magnesium increases serum calcification propensity in subjects with ESKD.

Design, setting, participants, & measurements

We conducted a single-center, randomized, double-blinded, parallel group, controlled clinical trial, in which we examined the effect of increasing dialysate magnesium from 1.0 to 2.0 mEq/L for 28 days compared with maintaining dialysate magnesium at 1.0 mEq/L on T50 in subjects undergoing hemodialysis for ESKD. The primary end point was the value of T50 at the end of the intervention.

Results

Fifty-nine subjects were enrolled in the trial, and of these, 57 completed the intervention and were analyzed for the primary outcome. In the standard dialysate magnesium group, T50 was 233±81 minutes (mean±SD) at baseline (mean of days −7 and 0) and 229±93 minutes at follow-up (mean of days 21 and 28), whereas in the high dialysate magnesium group, T50 was 247±69 minutes at baseline and 302±66 minutes at follow-up. The difference in T50 between the two groups at follow-up (primary analysis) was 73 minutes (between-group difference; 95% confidence interval, 30 to 116; P<0.001), and the between-group difference in serum magnesium was 0.88 mg/dl (95% confidence interval, 0.66 to 1.10; P=0.001).

Conclusions

Increasing dialysate magnesium increases T50 and hence, decreases calcification propensity in subjects undergoing maintenance hemodialysis.

Development and validation of a Health Policy Model of Type 2 diabetes in Chinese setting
Authors: Wu Bin , Ma Jing , Zhang Suhua , Zhou Lei , Wu Haixiang
Published: August 2018

Aim:
Due to the difference in epidemiology and outcomes between eastern and western populations with Type 2 diabetes mellitus (T2DM), an important challenge is determining how useful the outcomes from diabetes models based on western populations are for eastern patients. Consequently, the principal aim of this study was to develop and validate a Health Policy Model (Chinese Outcomes Model for T2DM [COMT]) for supporting Chinese medical and health economic studies.
Methods:
The model is created to simulate a series of important complications of T2DM diabetes based on the latest Risk Equations for Complications of Type 2 Diabetes, which was adjusted by adding the adjustment regulator to the linear predictor within the risk equation. The validity of the model was conducted by using a total of 171 validation outcomes from seven studies in eastern populations and ten studies in western populations. The simulation cohorts in the COMT model were generated by copying each validation study’s baseline characteristics. Concordance was tested by assessing the difference between the identity (45°) line and the best-fitting regression of the scatterplots for the predicted versus observed outcomes.
Results:
The slope coefficients of the best-fitting regression line between the predicted and corresponding observed actual outcomes was 0.9631 and the R
2
was 0.8701. There were major differences between western and eastern populations. The slope and R
2
of predictions were 0.9473 and 0.9272 in the eastern population and 1.0566 and 0.8863 in the western population, which showed more perfect agreement with the observed values in the eastern population than the western populations. The subset of macro-vascular and micro-vascular outcomes in the eastern population showed an identical tendency (the slope coefficient was close to 1), and mortality outcomes showed a slight tendency toward overestimation (the slope coefficient was close to 0.9208). Some degree of underprediction of macro-vascular and micro-vascular end points and overprediction of mortality end point was found in the western population.
Conclusion:
The COMT diabetes model simulated the long-term patient outcomes observed in eastern Asian T2DM patients with prediction accuracy. This study supports the COMT as a credible tool for Chinese healthcare decision makers. Further work is necessary to incorporate new local data to improve model validity and credibility.
Assessing the robustness of direct meta-analysis in the presence of heterogeneity
Authors: Ainsworth Claire
Published: August 2018

Aim:
To assess robustness of findings in recent systematic reviews of atypical antipsychotics in schizophrenia patients in the presence of heterogeneity.
Methods:
Relative efficacy was measured in seven direct comparisons of mean difference (MD) in average positive and negative syndrome scale total score and comparisons between conventional meta-analysis results and four alternate meta-analytic strategies using the difference in MD (ΔMD).
Results:
MDs in positive and negative syndrome scale total score were smaller in the conventional meta-analyses than those for three of the four analytic strategies. Such differences were small (all ΔMD <4). No considerable differences in effect size were observed in the limit meta-analysis comparison (|ΔMD| <1).
Conclusion:
The analyses validated the systematic review results and demonstrate the value of confirmatory sensitivity analysis.
Conditional power for assessing population interventions
Authors: Walker Alexander M , Coplan Paul M , Beachler Daniel C
Published: August 2018

Aim:
To calculate conditional power in comparative two-period studies with previously observed baseline data.
Method:
Isolate the variability attributable to the yet-to-observed data and modify the standard power formulae.
Results:
For illustration, we examine rates of opioid overdose before and after a reformulation of one opioid product. The null hypothesis posited no impact of the reformulation, alternative hypotheses posited possible impacts, and ancillary hypotheses posited different secular pre-post changes directly observable in comparators. Conditional power varied with the size of the comparator population and with the assumed pre-post change for the comparator.
Conclusion:
Pre-post designs can be initiated after the baseline period is over. Power calculations that are conditioned on observed baseline data account differently for variability in the baseline and follow-up periods.

El laberinto de Quetzalcóatl
Authors: OCAÑA JIMÉNEZ Lucila
Published: August 2018

Quetzalcóatl, la deidad principal de Mesoamérica y el elemento central de su cosmovisión, ha sido objeto de múltiples estudios; aquí presentamos los distintos caminos transitados para explicar su identidad. En tanto es un símbolo universal, son válidas las correspondencias de Quetzalcóatl en otras culturas, lejanas de Mesoamérica en el tiempo y el espacio. En cuanto a su presencia precolombina, proponemos explicarlo: a) A través de una concepción dualista en la que juega una parte importante la religión olmeca con sus prácticas y sus ideologías contrarias a Quetzalcóatl; b) Las luchas por la hegemonía política en Mesoamérica como conflictos religiosos, y c) Los estudios sobre la religión maya donde Quetzalcóatl, bajo los rasgos de las principales deidades, aparece en iconografía y en la mitología, lo que permite avanzar en los contenidos y significados de esta deidad.

Published: August 2018

El trabajo contiene un análisis de los conceptos básicos de la organización social y política del pueblo Azteca conquistado por los españoles en el siglo XVI. Resaltamos la estructura social, económica y política de este pueblo sustentada en lazos de sangre, en la conformación de grupos consanguíneos que convivieron y conservaron estructuras socioeconómicas colectivas, a lo cual correspondió una forma de la elección, por la vía del conceso, de sus dirigentes, lo cual se expresó, a su vez, en una administración comunitaria de los asuntos colectivos del pueblo azteca. Nuestro punto de vista contrasta con los análisis que parten de consideraciones y conceptos clasistas y la configuración de un Estado para explicar la forma de vida y de gobierno del pueblo dominante al momento de la conquista.

Los grupos económicos como estabilizadores financieros de la economía mexicana (1996-2000)
Authors: CASTAÑEDA RAMOS GONZALO
Published: August 2018

Las tasas anuales del crecimiento del PIB para el periodo 1996-2000 fueron muy superiores a las observadas en los últimos veinte años, situación que resulta contradictoria, tomando en cuenta que dicho crecimiento se dio en un contexto de crisis bancaria. Esta paradoja se explica por una recomposición en la estructura de capital de las empresas, dado que a partir de la crisis, éstas hicieron un mayor uso del crédito de proveedores y del financiamiento proveniente del mercado interno de capitales. En el artículo se afirma que, debido a la existencia de grupos económicos, las empresas con excedentes líquidos fueron capaces de prestar a sus filiales, sobre las que ejercen derechos de control, y así reducir los problemas de riesgo moral que limitaba el acceso a recursos financieros.

A Metadata Manifesto: The Need for Global Health Metadata
Authors: Fabreau Gabriel E , Minty Evan P , Southern Danielle A , Quan Hude , Ghali William A
Published: August 2018

Administrative health data recorded for individual health episodes (such as births, deaths, physician visits, and hospital stays) are being widely used to study policy-relevant scientific questions about population health, health services, and quality of care. Furthermore, an increasing number of international health comparisons are being undertaken with these data. An essential pre-requisite to such international comparative work is a detailed characterization of existing international health data resources, so that they can be more readily used in comparison studies across counties. A major challenge to such international comparative work is the variability across countries in the extent, content, and validity of existing administrative data holdings. Recognizing this, we have undertaken an international pilot process of compiling detailed data about data – i.e., a “meta-data catalogue” – for existing international administrative health data holdings. The methodological process for collecting these meta-data is described here, along with some general descriptive results for selected countries included in the pilot.

Authors: Hardjono Budiono , Ying Tan Bee
Published: August 2018

The cost of launching a totally new product or brand is usually very high accompanied by the risk of failure in an overcrowded market. Therefore, brand extension strategy is used due to its built in advantages. This research examined in depth, the factors in a brand extension which influence to customer perception about the existing brand in fast moving consumer goods (FMCG) sector. Four variables such as brand fit, perceived quality, brand familiarity and customer innovativeness, were used to establish the relationship with the customers’ perception. A questionnaire was developed and distributed to 200 respondents from hypermarket FMCG products’ consumers in Melaka city. It was found that in the context of personal hygiene products, only brand fit and perceived quality have a strong influence on the customer perception. Marketer should, however, carefully to evaluate their extension especially for local brand since not all factors in this extension significantly influence the customer perception.

This special issue aims at providing an empirical, analytically grounded perspective on foremost European higher education, while pointing at historical references, path-dependencies, critical junctures, and “original” institutional settings determined by the interaction of new forms with historical legacies. The contributions collected depict different facets of long term transformations of higher educations and, in some cases, their interplay with critical moments characterized by ample and abrupt transformations. Geographically, this issue includes study-cases localized in Central and Eastern Europe (the Czech Republic, Hungary, Poland and Romania), Western Europe (Italy and Germany) and Africa (Ghana). One of the express aims of the special issue is to bring together analyses focusing on national and/or local case studies, which have the potential to constitute the basis for comparative analysis.
Mapping students’ organizations in post-communist Romania: a structuration perspective
Authors: Proteasa Viorel , Andreescu Liviu , Botgros Vlad , Dodiță Alexandra
Published: August 2018

Who is who in Romanian student representation? In this article we answer this (apparently) simple question. We start with early 1990, when the Romanian campuses experienced ample changes – part of the societal transformations which swept over Central and Eastern Europe. Our ambitions in this text are twofold: (1) to construct a map of student federations in post-communist Romania, and (2) to identify and describe the waves of structuration of the field. In doing so, we revert to classical social theory and document the emergence of “organizational archetypes” of student representation. We identify two types of structuration, “bottom-up” and “top-down”. We find evidence regarding the resilience of the “bottom-up” organizational archetypes in relation to the successive attempts of “top-down” (re)structuration.
A MLMVN with Arbitrary Complex-Valued Inputs and a Hybrid Testability Approach for the Extraction of Lumped Models Using FRA
Authors: Aizenberg Igor , Luchetta Antonio , Manetti Stefano , Piccirilli Maria Cristina
Published: August 2018

A procedure for the identification of lumped models of distributed parameter electromagnetic systems is presented in this paper. A Frequency Response Analysis (FRA) of the device to be modeled is performed, executing repeated measurements or intensive simulations. The method can be used to extract the values of the components. The fundamental brick of this architecture is a multi-valued neuron (MVN), used in a multilayer neural network (MLMVN); the neuron is modified in order to use arbitrary complex-valued inputs, which represent the frequency response of the device. It is shown that this modification requires just a slight change in the MLMVN learning algorithm. The method is tested over three completely different examples to clearly explain its generality.
Enhancing Island Model Genetic Programming by Controlling Frequent Trees
Authors: Ono Keiko , Hanada Yoshiko , Kumano Masahito , Kimura Masahiro
Published: August 2018

In evolutionary computation approaches such as genetic programming (GP), preventing premature convergence to local minima is known to improve performance. As with other evolutionary computation methods, it can be difficult to construct an effective search bias in GP that avoids local minima. In particular, it is difficult to determine which features are the most suitable for the search bias, because GP solutions are expressed in terms of trees and have multiple features. A common approach intended to local minima is known as the Island Model. This model generates multiple populations to encourage a global search and enhance genetic diversity. To improve the Island Model in the framework of GP, we propose a novel technique using a migration strategy based on textit f requent trees and a local search, where the frequent trees refer to subtrees that appear multiple times among the individuals in the island. The proposed method evaluates each island by measuring its activation level in terms of the fitness value and how many types of frequent trees have been created. Several individuals are then migrated from an island with a high activation level to an island with a low activation level, and vice versa. The proposed method also combines strong partial solutions given by a local search. Using six kinds of benchmark problems widely adopted in the literature, we demonstrate that the incorporation of frequent tree information into a migration strategy and local search effectively improves performance. The proposed method is shown to significantly outperform both a typical Island Model GP and the aged layered population structure method.
Explanation by Idealized Theories
Authors: Niiniluoto Ilkka
Published: August 2018

The use of idealized scientific theories in explanations of empirical facts and regularities is problematic in two ways: they don’t satisfy the condition that the explanans is true, and they may fail to entail the explanandum. An attempt to deal with the latter problem was proposed by Hempel and Popper with their notion of approximate explanation. A more systematic perspective on idealized explanations was developed with the method of idealization and concretization by the Poznan school (Nowak, Krajewski) in the 1970s. If idealizational laws are treated as counterfactual conditionals, they can be true or truthlike, and the concretizations of such laws may increase their degree of truthlikeness. By replacing Hempel’s truth requirement with the condition that an explanatory theory is truthlike one can distinguish several important types of approximate, corrective, and contrastive explanations by idealized theories. The conclusions have important consequences for the debates about scientific realism and anti-realism.
Metaphysics, Function and the Engineering of Life: the Problem of Vitalism
Authors: Bognon-Küss Cécilia , Chen Bohang , Wolfe Charles T.
Published: August 2018

Vitalism was long viewed as the most grotesque view in biological theory: appeals to a mysterious life-force, Romantic insistence on the autonomy of life, or worse, a metaphysics of an entirely living universe. In the early twentieth century, attempts were made to present a revised, lighter version that was not weighted down by revisionary metaphysics: “organicism”. And mainstream philosophers of science criticized Driesch and Bergson’s “neovitalism” as a too-strong ontological commitment to the existence of certain entities or “forces”, over and above the system of causal relations studied by mechanistic science, rejecting the weaker form, organicism, as well. But there has been some significant scholarly “push-back” against this orthodox attitude, notably pointing to the 18th-century Montpellier vitalists to show that there are different historical forms of vitalism, including how they relate to mainstream scientific practice (Wolfe and Normandin, eds. 2013). Additionally, some trends in recent biology that run counter to genetic reductionism and the informational model of the gene present themselves as organicist (Gilbert and Sarkar 2000, Moreno and Mossio 2015). Here, we examine some cases of vitalismin the twentieth century and today, not just as a historical form but as a significant metaphysical and scientific model. We argue for vitalism’s conceptual originality without either reducing it to mainstream models of science or presenting it as an alternate model of science, by focusing on historical forms of vitalism, logical empiricist critiques thereof and the impact of synthetic biology on current (re-)theorizing of vitalism.

Published: August 2018

This article presents an extensive feasibility study of the use of optical satellite data for flood risk monitoring. The article presents a review of existing and archival satellite systems. The capabilities and restrictions of using earth observation data are presented, in relation to the identified threat and taking into account the size, genesis and cause. The initial results of the studies demonstrate the potential of very high and highresolution satellite imagery for the operational detection of damage and risk areas. In the presented approach, two analyses were conducted: bare soil detection and water range detection, based on different radiometric indices. As a result of the conducted research, the best results in bare soil detection were obtained using the MSAVI and NDVI indices. The most effective at delimiting water was the NDVI index. The automatization of satellite data processing from different satellite systems gives opportunities for hydrological services and crisis management professionals to access accurate and up-to-date information about the condition of levees for the early detection of flood risk.
Useful wasteland - the potential of undeveloped land in modification of urban green infrastructure based on the city of Poznań
Authors: Gałecka-Drozda Anna , Raszeja Elżbieta
Published: August 2018

Numerous barren land areas are found within administrative boundaries of cities. They include both former farmland located at the outskirts of cities, as well as vacant plots, postindustrial plots or former railway infrastructure plots. Barren plots are integral elements of the urban landscape and contemporary scientific concepts indicate their important role in the functioning of urban ecosystems. Abandoned land provides a potential for the development of green infrastructure and further development of recreation areas. At the same time some abandoned plots are informally adapted by local residents to suit their needs, transforming them into community gardens and recreation areas. This paper presents results of studies conducted by the authors in selected derelict areas in the city of Poznań. Analyses were conducted on their type, origin, size and location within the city. Observations were also recorded on the methods to adapt abandoned land by local communities.
Possibilities of Effective Inertisation of Self-Heating Places in Goaf of Longwall in Hard Coal Mines
Authors: Szlązak Nikodem , Piergies Kazimierz
Published: August 2018

Underground fires in coal mines belong to the most common hazards, the exposure to which frequently requires long term and costly rescue operations. It is mainly connected with the specific character of underground excavations which have limited volume. This makes the maximum permissible concentration of harmful gases rapidly exceeded and may also cause changes in air flow direction. The most certain way of improving a safety situation in Polish coal mining industry is taking early prevention steps. One of the prevention methods is inertisation of the atmosphere in longwall goaf. These activities rely on partial or total replacement of air or combustible atmosphere by inert gas. Thanks to them the risk of spontaneous fires hazard and gas explosion decreases. The main reason for the use of inert gases is to reduce the oxygen content to a limit which prevents further development of fire. This article presents methods for assessing inert gas to replace oxygen in the atmosphere in goaf.

The Unification of the Code Lists Provided within the Data Model Originating from the Inspire Technical Guidelines and the Ones Provided for Gesut Databases in the Context of Potential Exploitation in the Mining Industry
Authors: Zygmuniak Andrzej , Sokoła-Szewioła Violetta
Published: August 2018

This study is aimed at exposing differences between two data models in case of code lists values provided there. The first of them is an obligatory one for managing Geodesic Register of Utility Networks databases in Poland [9] and the second is the model originating from the Technical Guidelines issued to the INSPIRE Directive. Since the second one mentioned is the basis for managing spatial databases among European parties, correlating these two data models has an effect in easing the way of harmonizing and, in consequence, exchanging spatial data. Therefore, the study presents the possibilities of increasing compatibility between the values of the code lists concerning attributes for objects provided in both models. In practice, it could lead to an increase of the competitiveness of entities managing or processing such databases and to greater involvement in scientific or research projects when it comes to the mining industry. Moreover, since utility networks located on mining areas are under particular protection, the ability of making them more fitted to their own needs will make it possible for mining plants to exchange spatial data in a more efficient way.
Mines, Quarries and Landscape. Visuality and Transformation
Authors: Jimeno Carlos López , Torrijos Ignacio Díez , González Carmen Mataix
Published: August 2018

In this paper a review of two basic concepts is carried out: scenery and landscape integration, proposing a new concept: “visuality”, alternative to the classical “visibility” used in landscape studies related to mining activity, which explores the qualitative aspects that define the visual relationships between observer and environment. In relation to landscape integration studies, some reflections on substantive issues are made which induce certain prejudices at the time of addressing the issue of mining operations landscape integration, and some guidance and integration strategies are formulated. In the second part of the text, a new approach to the landscape integration of mines and quarries is raised, closely linked to the concept of visuality which are based on a basic goal: the re-qualification of the place, and give innovative answers to re-qualify the place and show how to catch the opportunity in the deep transformation generated by the development of mining activities. As a conclusion, a case study is presented in the last section, the landscape integration study conducted on marble exploitations Coto Pinos (Alicante, Spain), considered the largest ornamental rock quarry in Europe.

Coping Strategies of Intellectually Gifted and Common Adolescents Attending Grammar School in the Context of the Personality Dimensions Structure
Authors: Laznibatová Jolana , Fábik Dušan , Belica Ivan , Balážová Mária
Published: August 2018

Introduction: The aim of the present research was to find out the frequency of use of particular coping strategies by intellectually gifted and common adolescents and to evaluate this frequency in the context of the personality structure.

Methods: The sample consisted of 253 pupils attending grammar schools in Bratislava from 14 to 18 years of age. According to own criteria, 85 of them were identified as exceptionally intellectually gifted. They included those who scored 120 and more at least in 2 from 3 subtests IST-R-2000 (Words, Numerical Scale, Cubes), or who had an average score at least 120 in the given subtests. The intellectually gifted children were compared with children with common intellect in the frequency of use of particular coping strategies (CSI copying questionnaire). Moreover, we investigated a relationship between these strategies and personality traits (NEO-FFI) separately in the group of gifted children and separately in the group of pupils with a common intellect.

Results: Gifted pupils use social isolation strategy significantly more often and, on the contrary, they use considerably less the social support strategy than pupils with normal intellect. A significant moderately strong correlation (>0.35) of neuroticism with problem solving (negative), escape into fantasy and self-criticism, furthermore, extraversion with social support and social isolation (negative), and finally, conscientiousness and problem solving was indicated in gifted children. As far as common pupils, such correlations have been demonstrated between neuroticism and escape into fantasy and self-criticism, and between conscientiousness and escape into fantasy (negative).

Limits: The selected criterion for intellectual talent can be set to a higher level in the future. The intellectual talent was evaluated only by 3 subtests of IST-R-2000.

Conclusion: Gifted pupils in stressful situations more often tend to withdraw in comparison to common pupils. The personality dimensions – neuroticism, extraversion and conscientiousness are in relationship with management strategies. On the basis of the results, it can be assumed that the personality structure of gifted pupils is more strongly associated with the frequency of use of coping strategies than in common pupils.

Published: August 2018

Devido ao processo e as condições de trabalho oferecidas aos profissionais de enfermagem, a possibilidade de adoecimento físico e mental são grandes. Carga horária, setor e turno de atuação, demanda psicológica e física, exposição ao estresse, são fatores associados ao aumento de depressão nos trabalhadores de enfermagem. Esse é um tema de grande relevância para as instituições, pois poderá afetar o comportamento e as atitudes das pessoas, a qualidade de vida no trabalho e o desempenho desses profissionais. Esta revisão bibliográfica tem como objetivo realizar uma análise integrativa de publicações dos últimos 10 anos sobre depressão em profissionais de enfermagem em hospitais oncológicos. Para o desenvolvimento do estudo, foram analisados resultados obtidos em pesquisas de artigos científicos, sobre o tema abordado. Para o levantamento de dados deste estudo foi realizado nas bases de periódicos da BVS (Biblioteca Virtual de Saúde) acessando-se por meio do LILACS (Sistema Latino Americano e do Caribe de Informações em Ciências da Saúde), e no SCIELO (Scientific Eletronic Library Online), artigos a partir do ano de 2006. Os resultados obtidos permitiram uma análise da ocorrência de depressão nestes profissionais e forneceram subsídios para ações futuras baseadas na intervenção do problema e melhora das condições de trabalho.
Computational Strategies to Probe CH Activation in Dioxo-Dicopper Complexes
Authors: Lan Zhenzhuo , Mallikarjun Sharada Shaama
Published: August 2018

Our work addresses the long-standing question of the preferred mechanism of CH activation in dioxodicopper complexes, with implications for [Cu2O2]2+ -containing enzymes as well as homogeneous and heterogeneous catalysts, which are capable of performing selective oxidation. Using density functional theory (DFT), we show that the two proposed mechanisms, one-step oxo-insertion and two-step radical recombination, have very distinct and measurable responses to changes in the electrophilicity of N-donors in the catalyst. Using energy decomposition analysis, we calculate the electronic interactions that contribute to transition state stabilization, and the effect of N-donors on these interactions. The analysis shows that oxo-insertion, by virtue of possessing a late and charged transition state, is highly sensitive to N-donor electrophilicity and barriers decrease with more electron-withdrawing N-donors. On the other hand, the radical pathway possesses an early transition state and is therefore relatively insensitive to N-donor variations. One possible strategy, going forward, is the design and execution of complementary experiments to deduce the mechanism based on the presence or absence of N-donor dependence. We adopt an alternative approach where DFT results are contrasted with prior experiments via Hammett relationships. The remarkable agreement between experimental and calculated trends for oxo-insertion with imidazole N-donor catalysts presents compelling evidence in favor of the one-step pathway for CH activation.

La TOCFE (Theory of Contraints for Education) Teoría de Restricciones en Educación una posible solución, para el manejo de los conflictos individuales en la empresa
Authors: García Caicedo Jennifer
Published: August 2018

El objetivo de este documento es exponer la TOCFE (Theory of Contraints for Education) Teoría de Restricciones en Educación como una técnica de aprendizaje y enseñanza de competencias comunicativas,

de pensamiento y de resolución de conflictos, que aplicada a la resolución del conflicto individual en la empresa incrementa la habilidad para la toma de decisiones efectivas y permite converger las ideas de los involucrados hacia la unificación de esfuerzos para alcanzar un mismo objetivo y a su vez, incrementar los niveles de productividad en la organización. Inicialmente se caracteriza el conflicto en la empresa, después se realiza un contraste de la TOCFE con el método de negociación Harvard de Fisher y Ury, también aplicado en las empresas y finalmente se evidencian las ventajas de la Teoría de restricciones en la educación como propuesta de resolución del conflicto individual. De este análisis se concluye que la implementación de la TOCFE en la empresa es una decisión acertada pues permite que el talento humano realice adecuadamente los procedimientos que al ser correctamente ejecutados permiten la mejora de los resultados globales y de la

productividad.
Desempolvar Pedagogía del oprimido. Relectura crítica a 50 años de su publicación
Authors: Álvarez Gaytán Juan Fernando
Published: August 2018

El artículo pretende invitar a releer Pedagogía del oprimido. En torno a diversas líneas de discusión, se contrastará el pensamiento crítico contemporáneo para acercarse a categorías clave como despliegue epistemológico que potencian el discurso de Freire, en tanto razón liberadora. El trabajo se desarrolla mediante el procedimiento de la denuncia y anuncio, para situar su pensamiento en el momento actual. La propuesta es vincular estas líneas a una educación problematizadora que reestablezca las relaciones sociales y naturales, explicitar la filosofía y humanismo de Freire, y coadyuvar a la liberación de nuestro tiempo en cada uno de los espacios que genera la praxis de liberación.

Published: August 2018

This paper present an optimal Fractional Order PID (FOPID) controller based on Particle Swarm Optimization (PSO) for controlling the trajectory tracking of Wheeled Mobile Robot(WMR).The issue of trajectory tracking with given a desired reference velocity is minimized to get the distance and deviation angle equal to zero, to realize the objective of trajectory tracking a two FOPID controllers are used for velocity control and azimuth control to implement the trajectory tracking control. A path planning and path tracking methodologies are used to give different desired tracking trajectories.  PSO algorithm is using to find the optimal parameters of FOPID controllers. The kinematic and dynamic models of wheeled mobile robot for desired trajectory tracking with PSO algorithm are simulated in Simulink-Matlab. Simulation results show that the optimal FOPID controllers are more effective and has better dynamic performance than the conventional methods.
