Authors: Wang Kai , Lu Xin , Li Yu , He Xianghui , Liu Houlin , Kim Hyoung-Bum
Published: March 2019

In order to enhance the hydraulic efficiency of a liquid molten salt pump, the improvement on the pump was carried out through numerical and experimental methods. The internal flow field obtained by the numerical simulation was analysed. The results show that there are low-velocity area in the scroll region and large curvature of the streamline at the outlet. Geometric modification was made by trimming the back-blades of the impeller and filleting the sharp corner of the outlet pipe. The modified pump performance was verified by the experiments. The hydraulic efficiency, the pressure fluctuation, vibration characteristics between the original and modified pump were compared. The results showed that the hydraulic efficiency of the modified pump increased 7.4%. In addition, the pressure fluctuation and vibration intensity were also reduced compared with the original pump. This result shows that the geometric modification improves not only the hydraulic performance but also the structural properties.
A Haptic Model for the Quantum Phase of Fermions and Bosons in Hilbert Space Based on Knot Theory
Authors: Heusler Stefan , Ubben Malte
Published: March 2019

A generalization of the famous Dirac belt trick opens up the way to a haptic model for quantum phases of fermions and bosons in Hilbert space based on knot theory. We introduce a simple paper strip model as an aid for visualization of the quantum phases before and after Hopf-mapping, which can be extended to arbitrary spin states with almost no mathematical formalism. Knot theory arises naturally, leading to the Jones polynomials derived from Artin’s braid group for fermionic knots and for bosonic links. The paper strip model explicitly illuminates the relation between these knots and links within the S U ( 2 ) -representation of spin-jstates in C 2 j + 1 before Hopf-mapping and the number p = 2 j of nodes in the stellar representation in C P 1 after Hopf mapping.
Multiparametric Analytical Solution for the Eigenvalue Problem of FGM Porous Circular Plates
Authors: Żur Krzysztof Kamil , Jankowski Piotr
Published: March 2019

Free vibration analysis of the porous functionally graded circular plates has been presented on the basis of classical plate theory. The three defined coupled equations of motion of the porous functionally graded circular/annular plate were decoupled to one differential equation of free transverse vibrations of plate. The one universal general solution was obtained as a linear combination of the multiparametric special functions for the functionally graded circular and annular plates with even and uneven porosity distributions. The multiparametric frequency equations of functionally graded porous circular plate with diverse boundary conditions were obtained in the exact closed-form. The influences of the even and uneven distributions of porosity, power-law index, diverse boundary conditions and the neglected effect of the coupling in-plane and transverse displacements on the dimensionless frequencies of the circular plate were comprehensively studied for the first time. The formulated boundary value problem, the exact method of solution and the numerical results for the perfect and imperfect functionally graded circular plates have not yet been reported.
On a SIR Model in a Patchy Environment Under Constant and Feedback Decentralized Controls with Asymmetric Parameterizations
Authors: De la Sen Manuel , Ibeas Asier , Alonso-Quesada Santiago , Nistal Raul
Published: March 2019

This paper presents a formal description and analysis of an SIR (involving susceptible- infectious-recovered subpopulations) epidemic model in a patchy environment with vaccination controls being constant and proportional to the susceptible subpopulations. The patchy environment is due to the fact that there is a partial interchange of all the subpopulations considered in the model between the various patches what is modelled through the so-called travel matrices. It is assumed that the vaccination controls are administered at each community health centre of a particular patch while either the total information or a partial information of the total subpopulations, including the interchanging ones, is shared by all the set of health centres of the whole environment under study. In the case that not all the information of the subpopulations distributions at other patches are known by the health centre of each particular patch, the feedback vaccination rule would have a decentralized nature. The paper investigates the existence, allocation (depending on the vaccination control gains) and uniqueness of the disease-free equilibrium point as well as the existence of at least a stable endemic equilibrium point. Such a point coincides with the disease-free equilibrium point if the reproduction number is unity. The stability and instability of the disease-free equilibrium point are ensured under the values of the disease reproduction number guaranteeing, respectively, the un-attainability (the reproduction number being less than unity) and stability (the reproduction number being more than unity) of the endemic equilibrium point. The whole set of the potential endemic equilibrium points is characterized and a particular case is also described related to its uniqueness in the case when the patchy model reduces to a unique patch. Vaccination control laws including feedback are proposed which can take into account shared information between the various patches. It is not assumed that there are in the most general case, symmetry-type constrains on the population fluxes between the various patches or in the associated control gains parameterizations.
An Improved OTSU Algorithm Using Histogram Accumulation Moment for Ore Segmentation
Authors: Zhan Yantong , Zhang Guoying
Published: March 2019

When using image processing technology to analyze mineral particle size in complex scenes, it is difficult to separate the objects from the background with traditional algorithms. This paper proposes an ore image segmentation algorithm based on a histogram accumulation moment, which is applied to multi-scenario ore object location and recognition. Firstly, the multi-scale Retinex color restoration algorithm is used to improve the contrast in the dark region and eliminates the shadows generated by the stacked adhesion ores. Then, the zero-order and first-order cumulative moments close to the selected gray level are calculated, reducing the error caused by noise. Finally, the selected gray level gradually approaches the optimal threshold to avoid falling into local optimum. It can segment mineral images with unimodal or insignificant bimodal characteristic histogram effectively and accurately. Ore images in three different scenarios are used to verify the accuracy and effectiveness of the proposed method. The experimental results demonstrate that the proposed algorithm provides better segmentation results than other methods.
Coupling Conditions for Water Waves at Forks
Authors: Caputo Jean–Guy , Dutykh Denys , Gleyse Bernard
Published: March 2019

We considered the propagation of nonlinear shallow water waves in a narrow channel presenting a fork. We aimed at computing the coupling conditions for a 1D effective model, using 2D simulations and an analysis based on the conservation laws. For small amplitudes, this analysis justifies the well-known Stoker interface conditions, so that the coupling does not depend on the angle of the fork. We also find this in the numerical solution. Large amplitude solutions in a symmetric fork also tend to follow Stoker’s relations, due to the symmetry constraint. For non symmetric forks, 2D effects dominate so that it is necessary to understand the flow inside the fork. However, even then, conservation laws give some insight in the dynamics.
An Innovative Design of Substitution-Boxes Using Cubic Polynomial Mapping
Authors: Zahid Amjad Hussain , Arshad Muhammad Junaid
Published: March 2019

In this paper, we propose to present a novel technique for designing cryptographically strong substitution-boxes using cubic polynomial mapping. The proposed cubic polynomial mapping is proficient to map the input sequence to a strong 8 × 8 S-box meeting the requirements of a bijective function. The use of cubic polynomial maintains the simplicity of S-box construction method and found consistent when compared with other existing S-box techniques used to construct S-boxes. An example proposed S-box is obtained which is analytically evaluated using standard performance criteria including nonlinearity, bijection, bit independence, strict avalanche effect, linear approximation probability, and differential uniformity. The performance results are equated with some recently scrutinized S-boxes to ascertain its cryptographic forte. The critical analyses endorse that the proposed S-box construction technique is considerably innovative and effective to generate cryptographic strong substitution-boxes.
A Systems Thinking Approach to Designing Clinical Models and Healthcare Services
Authors: Khayal Inas S.
Published: March 2019

Chronic diseases are on the rise, increasing in number and treatment regimen complexity. Consequently, the needs of patients with chronic diseases are increasing and becoming more complex and multi-faceted. Such chronic conditions require addressing not only the physical body, but also psychosocial and spiritual health. The healthcare delivery system, however, organically organized into departments based on physical organ systems. Such a configuration makes it ill-suited to provide comprehensive multi-faceted healthcare services that span multiple departments and specialties (e.g., podiatry and endocrinology for diabetes; primary care and psychiatry for behavioral health; and palliative care physicians, chaplains, and social workers for end-of-life care). To deliver new services, the medical field typically designs new clinical models to base its new services on. Several challenges arise from typical approaches to designing healthcare services and clinical models, including addressing only single conditions, describing models only at a high-level of abstraction, and using primarily narrative documents called text-based toolkits for implementation. This paper presents and uses systems thinking as an alternative strategy to designing clinical system models and healthcare services to alleviate many of the current design challenges in designing integrated services for chronic conditions. An illustrative example taking a clinical model and describing it as a system model is presented.
The Versatile Roles of the tRNA Epitranscriptome during Cellular Responses to Toxic Exposures and Environmental Stress
Authors: Huber Sabrina M. , Leonardi Andrea , Dedon Peter C. , Begley Thomas J.
Published: March 2019

Living organisms respond to environmental changes and xenobiotic exposures by regulating gene expression. While heat shock, unfolded protein, and DNA damage stress responses are well-studied at the levels of the transcriptome and proteome, tRNA-mediated mechanisms are only recently emerging as important modulators of cellular stress responses. Regulation of the stress response by tRNA shows a high functional diversity, ranging from the control of tRNA maturation and translation initiation, to translational enhancement through modification-mediated codon-biased translation of mRNAs encoding stress response proteins, and translational repression by stress-induced tRNA fragments. tRNAs need to be heavily modified post-transcriptionally for full activity, and it is becoming increasingly clear that many aspects of tRNA metabolism and function are regulated through the dynamic introduction and removal of modifications. This review will discuss the many ways that nucleoside modifications confer high functional diversity to tRNAs, with a focus on tRNA modification-mediated regulation of the eukaryotic response to environmental stress and toxicant exposures. Additionally, the potential applications of tRNA modification biology in the development of early biomarkers of pathology will be highlighted.
Toxicity of Bacillus thuringiensis-Derived Pesticidal Proteins Cry1Ab and Cry1Ba against Asian Citrus Psyllid, Diaphorina citri (Hemiptera)
Authors: Fernandez-Luna Maria , Kumar Pavan , Hall David , Mitchell Ashaki , Blackburn Michael , Bonning Bryony
Published: March 2019

The Asian citrus psyllid (ACP), Diaphorina citri Kuwayama (Hemiptera), is an important pest of citriculture. The ACP vectors a bacterium that causes huanglongbing (HLB), a devastating and incurable disease of citrus. The bacterium Bacillus thuringiensis (Bt) produces multiple toxins with activity against a diverse range of insects. In efforts to provide additional control methods for the ACP vector of HLB, we identified pesticidal proteins derived from Bt for toxicity against ACP. The trypsin proteolytic profiles of strain-derived toxins were characterized. Strain IBL-00200, one of six strains with toxins shown to have basal activity against ACP was selected for liquid chromatography-mass spectrometry (LC-MS/MS) identification of the individual Cry toxins expressed. Toxicity assays with individual toxins derived from IBL-00200 were then performed. The activated form of the Cry toxins Cry1Ab and Cry1Ba were toxic to ACP with LC50 values of approximately 120 µg/mL. Disruption of the midgut epithelium was associated with the toxicity of both the IBL-00200-derived toxin mixture, and with Cry1Ba. With further optimization of the efficacy of Cry1Ab and Cry1Ba, these toxins may have practical utility against ACP. Bt toxins with activity against ACP may provide an additional tool for management of ACP and the associated HLB disease, thereby providing a more sustainable and environmentally benign approach than repeated application of broad-spectrum insecticides.
Harmful Effects and Control Strategies of Aflatoxin B1 Produced by Aspergillus flavus and Aspergillus parasiticus Strains on Poultry: Review
Authors: Fouad Ahmed Mohamed , Ruan Dong , El-Senousey HebatAllah Kasem , Chen Wei , Jiang Shouqun , Zheng Chuntian
Published: March 2019

The presence of aflatoxin B1 (AFB1) in poultry diets decreases the hatchability, hatchling weight, growth rate, meat and egg production, meat and egg quality, vaccination efficiency, as well as impairing the feed conversion ratio and increasing the susceptibility of birds to disease and mortality. AFB1 is transferred from poultry feed to eggs, meat, and other edible parts, representing a threat to the health of consumers because AFB1 is carcinogenic and implicated in human liver cancer. This review considers how AFB1 produced by Aspergillus flavus and Aspergillus parasiticus strains can affect the immune system, antioxidant defense system, digestive system, and reproductive system in poultry, as well as its effects on productivity and reproductive performance. Nutritional factors can offset the effects of AFB1 in poultry and, thus, it is necessary to identify and select suitable additives to address the problems caused by AFB1 in poultry.

Published: March 2019

Rift Valley fever (RVF) is a vector-borne viral disease of ruminants mainly, and man, characterized by abortions and neonatal deaths in animals and flu-like to more severe symptoms that can result in death in humans. The disease is endemic in Africa, Saudi Arabia and Yemen, and outbreaks occur following proliferation of RVF virus (RVFV) infected mosquito vectors. Vertebrate animal maintenance hosts of RVFV, which serve as a source of virus during inter-epidemic periods remain unknown, with wild and domestic suids being largely overlooked. To address this, we evaluated the virus neutralization test (VNT) for RVF antibody detection in suid sera, as a first step in assessing the role of suids in the epidemiology of RVF in Africa. Testing of experimental and field sera from domestic pigs and warthogs with a commercial RVF competitive antibody ELISA, served as a reference standard against which the VNT results were compared. Results indicate that VNT can detect anti-RVFV antibodies within three days post-infection, has an analytical specificity of 100% and diagnostic sensitivity and specificity of 80% and 97%, respectively. Although labour-intensive and time-consuming, the VNT proved suitable for screening suid sera and plasma for presence of RVFV antibodies in viraemic and recovered animals.

Authors: Amaral J. Kennedy , Taylor Peter C. , Teixeira Mauro Martins , Morrison Thomas E. “Tem” , Schoen Robert T.
Published: March 2019

Chikungunya fever (CHIKF) is an emerging viral infection that has spread widely, along with its Aedes vectors, throughout the tropics and beyond, causing explosive epidemics of acute illness and persistent disabling arthritis. The rheumatic symptoms associated with chikungunya virus (CHIKV) infection include polyarthralgia, polyarthritis, morning stiffness, joint edema, and erythema. Chronic CHIK arthritis (CCA) often causes severe pain and associated disability. The pathogenesis of CCA is not well understood. Proposed hypotheses include the persistence of a low level of replicating virus in the joints, the persistence of viral RNA in the synovium, and the induction of autoimmunity. In this review, we describe the main hypotheses of CCA pathogenesis, some of which support methotrexate (MTX) treatment which has been shown to be effective in preliminary studies in CCA.
Arthritogenic Alphavirus-Induced Immunopathology and Targeting Host Inflammation as A Therapeutic Strategy for Alphaviral Disease
Authors: Mostafavi Helen , Abeyratne Eranga , Zaid Ali , Taylor Adam
Published: March 2019

Arthritogenic alphaviruses are a group of medically important arboviruses that cause inflammatory musculoskeletal disease in humans with debilitating symptoms, such as arthralgia, arthritis, and myalgia. The arthritogenic, or Old World, alphaviruses are capable of causing explosive outbreaks, with some viruses of major global concern. At present, there are no specific therapeutics or commercially available vaccines available to prevent alphaviral disease. Infected patients are typically treated with analgesics and non-steroidal anti-inflammatory drugs to provide often inadequate symptomatic relief. Studies to determine the mechanisms of arthritogenic alphaviral disease have highlighted the role of the host immune system in disease pathogenesis. This review discusses the current knowledge of the innate immune response to acute alphavirus infection and alphavirus-induced immunopathology. Therapeutic strategies to treat arthritogenic alphavirus disease by targeting the host immune response are also examined.
A New Empirical Approach to Calculating Flood Frequency in Ungauged Catchments: A Case Study of the Upper Vistula Basin, Poland
Authors: Młyński Dariusz , Wałęga Andrzej , Stachura Tomasz , Kaczor Grzegorz
Published: March 2019

The aim of the work was to develop a new empirical model for calculating the peak annual flows of a given frequency of occurrence (QT) in the ungauged catchments of the upper Vistula basin in Poland. The approach to the regionalization of the catchment and the selection of the optimal form of the empirical model are indicated as a novelty of the proposed research. The research was carried out on the basis of observation series of peak annual flows (Qmax) for 41 catchments. The analysis was performed in the following steps: statistical verification of data; estimation of Qmax flows using kernel density estimation; determination of physiographic and meteorological characteristics affecting the Qmax flow volume; determination of the value of dimensionless quantiles for QT flow calculation in the upper Vistula basin; verification of the determined correlation for the calculation of QT flows in the upper Vistula basin. Based on the research we conducted, we found that the following factors have the greatest impact on the formation of flood flows in the upper Vistula basin: the size of catchment area; the height difference in the catchment area; the density of the river network; the soil imperviousness index; and the volume of normal annual precipitation. The verification procedure that we performed made it possible to conclude that the developed empirical model functions correctly.
Heavy Rainfall Triggering Shallow Landslides: A Susceptibility Assessment by a GIS-Approach in a Ligurian Apennine Catchment (Italy)
Authors: Roccati Anna , Faccini Francesco , Luino Fabio , Ciampalini Andrea , Turconi Laura
Published: March 2019

In recent decades, the Entella River basin (eastern Liguria) has been affected by several rainfall events that induced widespread shallow landslides and earth flows on the slopes; roads, buildings, structures and infrastructure suffered extensive damage due to the instability processes. In this paper, a GIS-based approach for analyzing and assessing a simplified landslide susceptibility in the Entella River catchment is presented. Starting from landslide information mainly provided from newspaper articles and unpublished reports from municipal archives, we performed a series of comparative analyses using a set of thematic maps to assess the influence of predisposing natural and anthropic factors. By evaluating the statistical distribution of landslides in different categories, we assigned weighted values to each parameter, according to their influence on the instability processes. A simplified, reproducible, but effective approach to assess landslide susceptibility in the study area was performed by combining all predisposing factors. The resulting scores in proneness to slope instability classes may be used to generate a simplified landslides susceptibility map of the catchment area which would be easy to regularly update every time a rainfall event that is able to trigger shallow landslides occurs; this would provide a useful tool for local authorities and decision makers for identifying areas which could potentially be affected by instability processes, and would help in determining the most suitable measures in land-planning and landslide risk management.

Published: March 2019

Wetlands used as cost-effective nature-based solutions provide environmental and socio-economic benefits to people locally and regionally. With significant loss of wetland areas due to expansion of forest, agriculture, and energy production industries, some countries, including Sweden, have begun providing economic support for environmental objectives for wetland conservation and restoration. Targeting such objectives and setting up relevant plans can decrease the risk of losing valuable wetland-related benefits and help achieve the United Nations Sustainable Development Goals (SDGs). Different ranges of wetland ecosystem services are broadly addressed by the SDGs, however, target-based assessments are required to better understand wetland functionality for sustainable development. This study investigates whether and how wetland ecosystems at local and regional scales can contribute to achieving the SDGs and their targets in Sweden. Scientific literature, policy documents, and international reports on Swedish wetland ecosystems are scrutinized to exemplify the SDGs and their targets, applying a scoring framework based on their interactions. This reveals that, overall, Swedish wetland ecosystems and implemented management plans can positively interact with 10 SDGs and 17 targets at different levels. The analysis also highlights synergies that need to be considered for integrated environmental governance and enhanced policy coherence for Swedish wetland management.

Published: March 2019

Satellite based rainfall estimation techniques have emerged as a potential alternative to ground based rainfall measurements. The Tropical Rainfall Measuring Mission (TRMM) precipitation, in particular, has been used in various climate and hydrology based studies around the world. While having wide possibilities, TRMM rainfall estimates are found to be inconsistent with the ground based rainfall measurements at various locations such as the southwest coast and Himalayan region of India, northeast parts of USA, Lake Victoria in Africa, La Plata basin in South America, etc. In this study, the applicability of TRMM estimates is evaluated over the Upper Ganga Basin (Himalayan catchment) by comparing against gauge-based India Meteorological Department (IMD) gridded precipitation records. Apart from temporal evaluation, the ability of TRMM in capturing spatial distribution is also examined using three statistical parameters namely correlation coefficient (r), mean absolute error (MAE) and relative bias (RBIAS). In the results, the dual nature of bias is evident in TRMM precipitation with rainfall magnitude falling in the range from 100 to 370 mm representing positive bias, whereas, rainfall magnitude above 400 mm, approximately, representing negative bias. The Quantile Mapping (QM) approach has been used to correct the TRMM dataset from these biases. The raw TRMM precipitation is found to be fairly correlated with IMD rainfall for post-monsoon and winter season with R2 values of 0.65 and 0.57, respectively. The R2 value of 0.41 is obtained for the monsoon season, whereas least correlation is found for the pre-monsoon season with an R2 value of 0.24. Moreover, spatial distribution of rainfall during post-monsoon and winter season is captured adequately; however, the limited efficiency of TRMM is reflected for pre-monsoon and monsoon season. Bias correction has satisfactorily enhanced the spatial distribution of rainfall obtained from TRMM for almost all the seasons except for monsoon. Overall, the corrected TRMM precipitation dataset can be used for various climate analyses and hydrological water balance based studies in the Himalayan river basins.
INTELLIGENCE AND THINKING IN CONCEPTS OF CONTEMPORARY EPISTHEMOLOGY
Authors: Halchenko Maksym
Published: March 2019

Epistemological structures do not appear to be the conscious meaning of thinking, but they define its concrete form. This phenomenon belong to both everyday and scientific thinking. The growth of the number of cognitive theories reveals their social aspect, the connection with the Bergsonian theory of anti-intellectual intuitionism. Adaptation of intelligence to social history provided the thinking with the internal structure in accordance with the realities of the outside world. Of great importance in the study of cognition is the concept of "autopoiesis" - the theory of self-reproduction of living systems. This is the first scientific theory that overcomes the division of reason and matter. The cognitive preconditions of the activity of thinking serve as means of interdisciplinary cooperation on its complex and contradictory processes.

Factores Claves de La Responsabilidad Social Empresarial
Authors: Palacios Sarmiento Tania , Velásquez Oswaldo
Published: March 2019

Desde el punto de vista empresarial, la responsabilidad social empieza a desarrollarse a principios del siglo XX y fue después que se fortalecieran parámetros sobre los trabajadores dentro de la organización económica en Estados Unidos. Algunos de estos aspectos eran acerca de cómo los trabajadores debían tener participación en las decisiones empresariales, ya que esto ayudaba a desarrollar en ellos más confianza, fidelidad, correspondencia y reciprocidad con la empresa. Durante la década de 1960, la economía establecía que el generar utilidades respetando la ley era la responsabilidad a la que debían regirse las empresas. Luego, en la década de 1980 se consideró la teoría que las empresas deben realizar sus actividades satisfaciendo las demandas de la sociedad, debido a los impactos que estos causan en la misma. Pero ciertamente en la década de 1990 es cuando se da el apogeo de la RSE por causas como la globalización, el desarrollo tecnológico, el incremento de inequidad social y la concientización de la sociedad acerca de los agravantes sociales y del medioambiente.

El objetivo de este trabajo fue presentar los sustentos teóricos del diagnóstico psicopedagógico en el contexto de la educación inclusiva. El contenido del artículo formó parte de una investigación con la que se opta al título Magíster en Educación mención Inclusión Educativa y Atención a la Diversidad. Se partió de una valoración sobre las definiciones de diagnóstico, principios y objetivos del diagnóstico psicopedagógico, funciones del diagnóstico psicopedagógico y tipos de diagnóstico. Se emplearon métodos teóricos como el análisis y la síntesis, de lo abstracto a lo concreto y el histórico lógico, que permitieron realizar la valoración teórico –conceptual del diagnóstico psicopedagógico en el contexto de la educación inclusiva.

El pensamiento dominante en la educación actual, está fundamentado en la idealización de la escuela para todos, sin desestimar la libertad individual frente a las luchas sociales, para “ejercer el derecho al estudio, al reconocimiento de la diversidad étnica y cultural” y a la valoración de su historia y la de sus antepasados para no revivir el colonialismo que involucionó a las culturas de muchos pueblos sometidos para el enriquecimiento de unos pocos.El estudio tiene como objetivo principal destacar la influencia de la otredad en la construcción de la Escuela para todos, así como, reconocer y valorar que la “definición del Otro” es parte de lo que se reconoce en uno mismo y evidencia sus características culturales; es por ello que se toma como estrategia metodológica el análisis e interpretación de algunas reflexiones de pedagogos y escritores que aportan al desarrollo del tema, tales como Elizabeth Sosa, Octavio Paz, Paulo Freire (1999) y Brunner (1996).El resultado del análisis recalca la importancia del término “otredad” en la convivencia humana para comprender por qué algunos grupos excluyen al o los Otros, la respuesta está en las diferencias, las mismas que el docente debe conocer para ser el primero en valorar, respetar e inspirar lo mismo en y para todos los participantes de su clase.La conclusión destaca que la alteridad u otredad pueden identificarse en las relaciones humanas, en la cultura, la raza, la orientación sexual, las ideologías, etc., sin embargo, ninguna diferenciación humana llámese xenofobia, racismo u otra, se cumple totalmente, ya que “nosotros y los otros” formamos parte del universo; he allí la importancia de saber coexistir y promover el crecimiento de cada individuo, empleando la dialogicidad como una de las herramientas humanas más efectivas para interactuar desde la otredad.

Las mujeres a nivel mundial son uno de los grupos mas vulnerables. Debido a falta de educación e independencia económica muchas mujeres son victimas de violencias. Esta investigación analiza como la educación y el trabajo tiene algún efecto en la disminución de la violencia en el hogar. Para ello, se realizo un estudio cualitativo donde se trabajo con 3 familias de bajos recursos en Duran, Ecuador por un periodo de 9 meses. También, el estudio esta compuesto de una parte cuantitativa, donde se uso el cuestionario IMAGES. Se entrevisto y encuesto a 150 personas en Guayaquil y Duran. Encontramos que tanto la education como el empoderamiento laboral en la mujer tiene un efecto positivo par disminuir la violencia familiar.

The serotonin 5-hydroxytryptamine 3 receptor (5-HT3R) plays a unique role within the seven classes of the serotonin receptor family, as it represents the only ionotropic receptor, while the other six members are G protein-coupled receptors (GPCRs). The 5-HT3 receptor is related to chemo-/radiotherapy provoked emesis and dysfunction leads to neurodevelopmental disorders and psychopathologies. Since the development of the first serotonin receptor antagonist in the early 1990s, the range of highly selective and potent drugs expanded based on various chemical structures. Nevertheless, on-off-targeting of a pharmacophore’s activity with high spatiotemporal resolution as provided by photopharmacology remains an unsolved challenge bearing additionally the opportunity for detailed receptor examination. In the presented work, we summarize the synthesis, photochromic properties and in vitro characterization of azobenzene-based photochromic derivatives of published 5-HT3R antagonists. Despite reported proof of principle of direct azologization, only one of the investigated derivatives showed antagonistic activity lacking isomer specificity.
Allocutive agreement in Korean under cyclic Agree
Authors: Kim Sanghee
Published: March 2019

Korean is a language known to lack agreement, but there is one salient agreement that happens: honorific agreement. A basic example is that whenever the subject is suffixed with an honorifying nominal form, -kkeyse, it agrees with a verbal suffix, -si. The condition for honorific agreement is that the subject must have an honorifying feature [+hon] and has to be [+human]. Nevertheless, I newly introduce a case where honorifying verbal suffix -si is used even when the subject does not have a [+hon, +human] feature. I suggest that this is a type of allocutive agreement (i.e., morphosyntactic agreement with the hearer). Based on Speech Act projection suggested by Haegeman & Hill (2013), I propose a structural representation that integrates discourse participants into syntactic representation. I also predict the phenomenon by adopting the framework of cyclic Agree proposed by Béjar & Rezac (2009).
