Una interpretación desde la perspectiva de la hermenéutica analógica: la educación basada en la convivencia
Authors: Barragán Machado Nancy , Evangelista Ávila Iram Isaí , Chaparro Medina Paola Margarita
Published: April 2019

El presente trabajo tiene como objetivo mostrar ciertos lineamientos de la educación basada en la convivencia y algunos de los problemas que se presentan cuando se intenta implementar en una cultura que privilegia la competencia. Como referencia se toma en cuenta el informe realizado a la UNESCO por la Comisión Internacional sobre la Educación para el Siglo XXI, presidida por Jacques Delors, en el cual se establecen los cuatro pilares de la educación, siendo de nuestro particular interés el pilar que se refiere a aprender a vivir juntos. Para este trabajo requerimos de la hermenéutica analógica como actitud y método, pues esta tiene en su esencia un camino intermedio que evita las interpretaciones absolutistas o relativistas. Esta exposición concluye en que una visión analógica permite otorgar claridad en cuanto a las necesidades que deben conciliarse en la educación: aprender habilidades técnicas para un desempeño en el mundo actual y aprender habilidades socioemocionales centradas en el trabajo en equipo, la cooperación, el respeto y el afecto por los demás.

La investigación educativa y su vinculación con las necesidades sociales
Authors: Trujillo Holguín Jesús Adolfo
Published: April 2019

La actividad investigativa precisa no solamente del desarrollo de un proceso sistemático de interrogación y búsqueda de datos para comprobar supuestos, sino que obliga al investigador a que, una vez concluido su trabajo, encuentre los mecanismos para la difusión de resultados, de manera que sean útiles para la solución de problemáticas específicas; o bien, para que inciten a la generación de nuevas interrogantes que sean el principio de un nuevo proceso de indagación. Desde hace unas cuantas décadas, cuando la investigación educativa en México se encontraba en proceso de gestación, el posgrado comenzó a visualizase como un espacio para la generación de conocimiento, aunque permeado con la idea de que el proceso investigativo concluía cuando los estudiantes presentaban la tesis y cuando los ejemplares impresos llegaban hasta el estante de una biblioteca. Poco a poco los investigadores educativos avanzaron en su carrera de profesionalización y en la adquisición de una identidad propia como comunidad científica, una vez que comenzaron a abrirse espacios de diálogo e interacción para la comunicación de resultados (Latapí, 2008).

Drug Assessment Instruments and Their Relevance with Women
Authors: Choi, Ph.D., M.S.W. Sam
Published: April 2019

Reviews of literature reveal that there is recognition of the importance of development women-sensitive drug assessment instrument. However, validating existing drug assessment instruments with women and development of women-sensitive assessment tools remain in opaque areas for scholarly inquiry. The purposes of this paper are twofold: 1) to investigate outcomes of evaluation studies of existing drug abuse assessment instruments in woman population samples; 2) to examine the status of the empirical studies on psychometric properties among those instruments. This review investigates four drug assessment instruments including ASI, DAST, DUSI, and MMPI-s. A review of literature yields little evidence that research has been responding to ensure gender differences in drug assessment instruments. This study finding suggests the great demands of further research on validating existing drug assessment instruments and development of women-sensitive assessment instruments.

The welfare centers in the society are among the most dynamic social institutions in the world. Community centers keep people in the center of development, as they have a commitment to regional intervention. To do this, governments provide an institutional link between people and the various private stakeholder coalitions that make up their communities. Community centers also participate in a wide range of social change activities, including advocacy with and on behalf of the community to reform basic social, political and economic conditions.In the world, social workers serve as primary professional leaders of an effective community centers movement. In the literature review, few studies have been found which examine the relations between social services and social Works with respect to the countries. Data Collection Technique of Research; in order to be used in this study, a literature review on the subject was made, and books, theses, articles, and other resources were scanned.

POROSITY, PERMEABILITY AND MICROSTRUCTURE OF FOAMED CONCRETE THROUGH SEM IMAGES
Authors: Shawnim P. , Mohammad F.
Published: April 2019

This paper examined the foamed concrete (FC) for permeability of total and capillary water absorption, at 28 days of air sealed curing. The microstructure of 15 selected FC specimens was investigated to determine permeability in relation to porosity and density using Scanning Electron Microscopy (SEM) images. The FC specimens of the densities (1100, 1600, and 1800) kg/m3 were made using fine sand and brick aggregates with toner and MK inclusion as additives. The microstructural investigation of the FC revealed, porosity measure as a percentage ratio of the area under investigation to be in the range of (39.65 to 77.7) %. The pore size is in the range of (0.01 to 70) µm, depending on the type of additive, for the mixes containing toner and MK, it is in a fine range of (0.01 to 10.0) µm. For the FC specimens, the finer the pore size, the less permeable and the stronger it is. Permeability is porosity and strength dependent, whereby high porosity leads to high permeability and low compressive strength for FC mixes made with sand or brick only with no additive inclusion. Meanwhile, the FC mixes made with the inclusion of additives, such as the toner and MK20 mixes, showed an evenly spread net of independent air voids with a regular shape within their matrix, which is beneficial in decreasing permeability. Therefore, besides the porosity and strength, the fineness of the pore matrix and the shape factor of the pores are two other key factors in controlling permeability. Toner and MK20 inclusion can enhance the capillary water absorption to reach almost water tight. Besides, MK30 and MK50 inclusion displayed adverse effect on permeability. Depending on the type of filler, the additive, and the percentage ratio of the porosity of the FC matrix at (1600 and 1800) kg/m3 densities, it is possible to produce FC with compressive strength between (55.1 and 30) N/mm2.
Stochastic Effects on the Dynamics of the Resonant Structure of a Lorentz Force MEMS Magnetometer
Authors: Bagherinia Mehrdad , Mariani Stefano
Published: April 2019

Resonance features of slender mechanical parts of Lorentz force MEMS magnetometers are affected by the (weakly) coupled thermo-electro-magneto-mechanical multi-physics governing their dynamics. We recently showed that reduced-order models for such parts can be written in the form of the Duffing equation, whose nonlinear term stems from the mechanical constraint on the vibrations and is affected by the driving voltage. As some device performance indices vary proportionally to the amplitude of oscillations at resonance, an optimization of the operational conditions may lead to extremely slender, imperfection-sensitive movable structures. In this work, we investigate the effects of imperfections on the mechanical response of a single-axis magnetometer. At the microscopic length-scale, imperfections are given in terms of uncertainties in the values of the over-etch depth and of the Young’s modulus of the vibrating polycrystalline silicon film. Their effects on the nonlinear structural dynamics are investigated through a Monte Carlo analysis, to show how the output of real devices can be scattered around the reference response trend.
Growth Intention and Growth in Small Accounting Firms
Authors: Kolvereid Lars , Åmo Bjørn Willy
Published: April 2019

Previous research has found that owner/manager growth intention is related to subsequent firm growth, but growth intention alone only explains about 4–5% of the variance in actual firm growth. The purpose of this study is to investigate factors in addition to growth intention that may help us to explain a higher proportion of the variance in firm growth. We selected three factors for our study: Entrepreneurial orientation, versatile human resources and labor productivity. We tested the hypotheses in a sample of small Norwegian accounting firms. The findings indicate that, after controlling for growth intention, versatile human resources and labor, productivity contributed to the explanation of the variance in sales and employment growth, while entrepreneurial orientation has no such additional effect.

Cattle grazing is an important economic activity in the tallgrass prairie systems in the Great Plains of the United States. Tallgrass prairie may respond differently to grazing management (e.g., high and low grazing intensity) under variable climate conditions. This study investigated the responses of two replicated (rep a and rep b) tallgrass prairie systems to continuous (C) and rotational (R) grazing under different climate conditions over a decade (2008–2017). The enhanced vegetation index (EVI) and gross primary productivity (GPP) were compared between grazing systems (C vs. R), while EVI was compared among paddocks under rotational grazing to show the impacts of time since grazing. The average EVI in rep a was usually higher than that in rep b which could be explained by different land characteristics (e.g., soil types) associated with different landscape positions. Similar to EVI, GPP was usually higher in rep a than rep b. The average growing season EVI and GPP were higher in rotational grazing than continuous grazing in rep b but not in rep a. The average EVI of paddocks in rotational grazing systems only converged in the growing season-long drought year (2011). In other years, EVI values varied from year to year and no paddock consistently outperformed others. The variations in EVI among rotational grazing paddocks in both reps were relatively small, indicating that rotational grazing generated an even grazing pressure on vegetation at annual scale. Overall, climate and inherent pasture conditions were the major drivers of plant productivity. However, the stocking rate in continuous grazing systems were reduced over years because of deteriorating pasture conditions. Thus, the results indirectly indicate that rotational grazing improved grassland productivity and had higher stocking capacity than continuous grazing systems under variable climate conditions. Adaptive grazing management (adjustment in stocking rates and season of use to adapt to changing climatic conditions) instead of a fixed management system might be better for farmers to cooperate with changing climatic conditions.

The aim of this study was to determine how polyunsaturated fatty acids (PUFA) supplementation can affect the productive and reproductive performance in dairy cows subjected to a fixed-time artificial insemination (TAI) protocol under farm conditions. One hundred and ninety-eight Holstein non-pregnant cows were used. Treatments consisted of a control diet (CON), without added oil, and two diets supplemented with either 2.3% soybean oil (SOY) or 2.3% linseed oil (LIN) as dry matter. The diets were formulated to be isoenergetic and isoproteic. Dry matter intake and milk yield were similar among treatments (p > 0.05). Both the percentage of fat (p = 0.011) and protein (p = 0.022) were higher in milk from animals not fed with oil (CON). The greatest saturated fatty acid (SFA) concentration (p < 0.0001) was observed in milk from cows fed the control diet, without added oil. The monounsaturated fatty acids (MUFA), PUFA, and the n-3 PUFA content was higher (p < 0.0001) in the milk from animals fed with oil with respect to the control treatment. The C18:2 cis-9, trans-11 in the milk of animals fed with oil supplements was significantly higher (p < 0.0001) than in that of the control group. Animals supplemented with linseed oil tended to show higher plasma progesterone level (p = 0.09) and a higher number of pregnant cows on the first artificial insemination (p = 0.07). These animals tended to reduce the number of TAI (p = 0.08). In brief, results showed that vegetable oils rich in PUFA supplementation considerably improve the nutritional profile of milk. PUFA n-3 supplementation slightly improves some reproductive parameters in dairy cows subjected to the fixed-time artificial insemination (TAI) protocol.

Alzheimer’s disease (AD) is a neurodegenerative disorder characterized by dementia and the aggregation of the amyloid beta peptide (Aβ). Aβ25–35 is the most neurotoxic sequence, whose mechanism is associated with the neuronal death in the Cornu Ammonis 1 (CA1) region of the hippocampus (Hp) and cognitive damage. Likewise, there are mechanisms of neuronal survival regulated by heat shock proteins (HSPs). Studies indicate that pharmacological treatment with flavonoids reduces the prevalence of AD, particularly epicatechin (EC), which shows better antioxidant activity. The aim of this work was to evaluate the effect of EC on neurotoxicity that causes Aβ25–35 at the level of spatial memory as well as the relationship with immunoreactivity of HSPs in the CA1 region of the Hp of rats. Our results show that EC treatment reduces the deterioration of spatial memory induced by the Aβ25–35, in addition to reducing oxidative stress and inflammation in the Hp of the animals treated with EC + Aβ25–35. Likewise, the immunoreactivity to HSP-60, -70, and -90 is lower in the EC + Aβ25–35 group compared to the Aβ25–35 group, which coincides with a decrease of dead neurons in the CA1 region of the Hp. Our results suggest that EC reduces the neurotoxicity induced by Aβ25–35, as well as the HSP-60, -70, and -90 immunoreactivity and neuronal death in the CA1 region of the Hp of rats injected with Aβ25–35, which favors an improvement in the function of spatial memory.

Published: April 2019

Red fruits are considered a major source of antioxidant compounds in the human diet. They usually contain anthocyanins, phenolic pigments that confer them multiple health-promoting properties. The health benefits of these bioactive phytocompounds are strongly related to their bioavailability, which has been reported to be low. The aim of the present study is to investigate the changes in antioxidant capacity and anthocyanin content of Cornelian cherry fruit extract during gastrointestinal digestion. Thus, the work was designed using a simulated in vitro digestion model. The antioxidant capacity (AA) was tested by the 2,2-azinobis (3-ethylbenzothiazolyne-6-sulphonic acid) radical cation (ABTS) method, while quantification of anthocyanins (TAC) was accomplished by the means of the pH differential method and high performance liquid chromatography (HPLC). The results showed that gastric digestion had no significant effect on the TAC of the extract, while the AA slightly increased. After duodenal digestion, only 28.33% of TAC and 56.74% of AA were maintained. Cornelian cherries’ anthocyanins were stable in stomach, so they can be absorbed in order to manifest their antioxidant capacity at the cellular level. The duodenal digestion dramatically decreased the TAC and AA level in the fruit extract.

Grid algorithmic trading has become quite popular among traders because it shows several advantages with respect to similar approaches. Basically, a grid trading strategy is a method that seeks to make profit on the market movements of the underlying financial instrument by positioning buy and sell orders properly time-spaced (grid distance). The main advantage of the grid trading strategy is the financial sustainability of the algorithm because it provides a robust way to mediate losses in financial transactions even though this also means very complicated trades management algorithm. For these reasons, grid trading is certainly one of the best approaches to be used in high frequency trading (HFT) strategies. Due to the high level of unpredictability of the financial markets, many investment funds and institutional traders are opting for the HFT (high frequency trading) systems, which allow them to obtain high performance due to the large number of financial transactions executed in the short-term timeframe. The combination of HFT strategies with the use of machine learning methods for the financial time series forecast, has significantly improved the capability and overall performance of the modern automated trading systems. Taking this into account, the authors propose an automatic HFT grid trading system that operates in the FOREX (foreign exchange) market. The performance of the proposed algorithm together with the reduced drawdown confirmed the effectiveness and robustness of the proposed approach.
A Size-Dependent Cost Function to Solve the Inverse Elasticity Problem

Published: April 2019

Characterizing nonhomogeneous elastic property distribution of solids is of great significance in various engineering fields. In this paper, we observe that the solution to the inverse problem utilizing the standard optimization-based inverse approach is sensitive to the sizes of inclusions. The standard optimization-based inverse approach minimizes a cost function, containing the absolute error between the measured and computed displacements in L2 norm. To address this issue, we propose a novel inverse scheme to characterize nonhomogeneous shear modulus distribution of solids. In this novel method, the cost function is modified, and is dependent on the size of the inclusions. A number of simulated experiments are performed, and demonstrate that the proposed approach is capable of improving the shear modulus contrast in inclusions and reducing the size sensitivity. Furthermore, a theoretical analysis is conducted to validate what we have observed in simulated experiments. This theoretical analysis reveals that what we have observed in the simulated experiments is not induced by the numerical issues Instead, the size sensitivity issue is induced by regularization. The findings of this work encourage us to propose new cost functions for the optimization-based inverse approach to improve the quality of the shear modulus reconstruction.
