Accesibilidad de la vivienda: un tema de bienestar social. El caso de la zona metropolitana del Valle de México
Authors: Lara-Pulido José Alberto , Estrada-Díaz G. , Guevara-Sanginés A. , Uribe M.
Published: October 2019

Este trabajo examina la relación entre la accesibilidad de una vivienda con su entorno y su precio. A partir de un modelo de precios hedónicos se analiza el valor que le asignan las personas a tener accesibilidad a elementos de su entorno como equipamientos y redes de transporte. Los resultados indican que las personas valoran más habitar en lugares en los que puedan acceder a otros lugares que están a una distancia mayor a 12 000 m, pero a la vez valoran su privacidad, lo cual hace que prefieran viviendas más apartadas (en un radio menor a 500 m) de redes viales transitadas. Este resultado es relevante para la planeación urbana, porque sugiere que una política de desarrollo urbano podrá generar mayores beneficios para la población en tanto se enfoque a proveer mayor accesibilidad a mayores niveles de integración; a niveles menores es mejor que los propios agentes definan la configuración del entorno.
Diagnóstico de la calidad de las aguas superficiales en la región de Los Altos Norte de Jalisco, México
Authors: Castañeda Villanueva Aldo Antonio , Flores López Hugo Ernesto , Cuevas-Villanueva Ruth Alfaro
Published: October 2019

La región de los Altos Norte se ubica en la parte noreste del estado de Jalisco dentro de la cuenca de Río Verde en la región Hidrológica Lerma - Santiago. En esta región, el principal producto del sector ganadero es el huevo para plato que representa el 49.8% de la producción total (2013). Gran parte de los residuos generados en la región por la actividad doméstica, pecuaria e industrial no son manejados adecuadamente ocasionando graves deterioros ambientales. En el presente trabajo se comparan los análisis de 20 puntos de muestreo de aguas superficiales distribuidos en los 8 municipios que conforman la región en dos ocasiones (2014 y 2016), detectándose cierto grado de contaminación en los cuerpos de agua estudiados en todos los municipios. Los que presentan mayor grado de contaminación son: Lagos de Moreno, San Juan de Los Lagos, Unión de San Antonio, Villa Hidalgo y en la última evaluación San Diego de Alejandría, los municipios con menor grado de contaminación son Encarnación de Díaz, Ojuelos y Teocaltiche.
Diseñando sistemas territoriales en la recolección de aparatos eléctricos y electrónicos en desuso mediante optimización metaheurística
Authors: Rios Mercado Roger Z , Fernández Elena
Published: October 2019

En este artículo se presenta el estudio de un problema de diseño de territorios de máxima dispersión territorial, motivado por una aplicación real en el campo de recolección y reciclaje de aparatos eléctricos y electrónicos en desuso en Europa. El problema consiste en encontrar una asignación de los centros de recolección a las corporaciones recolectoras que maximice una medida de dispersión territorial. El contexto matemático incluye como criterios de planificación, equilibrar la distribución de los hogares entre las distintas corporaciones de acuerdo a sus porcentajes de venta de mercado, así como evitar monopolios regionales. Se aplica una metaheurística tipo Greedy Randomized Adaptative Search Procedures (GRASP) que incorpora tres mecanismos de construcción de soluciones y tres diferentes tipos de vecindarios para las estrategias de búsqueda, para la mejora de soluciones. El algoritmo se ha evaluado en varios conjuntos de instancias generados aleatoriamente a partir de datos reales proporcionados por la empresa en territorio alemán. Los resultados obtenidos indican la eficacia del método propuesto dado que en tiempos de cómputo relativamente rápidos, pudieron obtenerse soluciones de calidad muy superior a la de las obtenidas por la empresa, tanto respecto a la medida de compacidad como respecto a las restricciones de balanceado.

Authors: Peña Joya Karen Elizabeth , Téllez López Jorge , Quijas Sandra , Cupul-Magaña Fabio Germán
Published: October 2019

El estudio de las lagartijas (Reptilia: Squamata) es de gran interés para los investigadores de todo el mundo, principalmente porque han sido buenos modelos para estudios biológicos (morfología, ecología, comportamiento, fisiología, entre otros). Este estudio se enfocó en hacer un análisis cuantitativo de las publicaciones científicas que analizan las comunidades de lagartijas y las características de sus hábitats. Se realizó la búsqueda electrónica de artículos sobre los estudios de las comunidades de lagartijas y los atributos del hábitat que se consideran en su estudio. Este trabajo se basó en las publicaciones (1980 al 2015) registradas en la base de datos ISI Web of Knowledge a nivel mundial. Un total de 47 artículos fueron encontrados para este periodo. La mayor parte (68%) se realizaron con datos obtenidos en las regiones tropicales del planeta. Brasil fue el país que concentró el mayor número de artículos (15 de 47). Los resultados mostraron que el 55.31% de los artículos se publicaron en dos revistas. El método predominante de muestreo utilizado fue el de búsquedas visuales en sitios determinados (48.94%). La riqueza y abundancia de especies fueron los atributos estructurales de las comunidades de lagartijas más comúnmente citados en los artículos (51.06%). El estrato arbóreo fue la variable más citada en la caracterización del hábitat (19 artículos de 47 artículos). En general, fueron cuatro los métodos estadísticos utilizados con mayor frecuencia en los artículos: Análisis de Varianza (Anova) (16 artículos), Análisis de Correlación (14 artículos), Escalamiento Multidimensional No Métrico (11 artículos) y Análisis de Regresión (10 artículos). Se discuten los resultados encontrados.
Distribución espacial de las poblaciones de huevos de Bactericera cockerelli Sulc. en el cultivo de tomate de cáscara (Physalis ixocarpa Brot.)
Authors: Rivera-Martínez Roberto , Ramírez-Dávila José Francisco , Acosta-Guadarrama Agustin David
Published: October 2019

La producción de tomate de cáscara ha sufrido pérdidas económicas del 70% al 80% por la presencia de amarillamiento y aborto floral cuyo agente causal se le atribuye al insecto Bactericera cockerelli Sulc. Las alternativas de control de este insecto han carecido de eficacia, por lo tanto, el objetivo del trabajo fue determinar la distribución espacial de las poblaciones de huevos de B. cockerelli en cuatro parcelas de tomate de cáscara, por medio de la geoestadística, en Luvianos, Estado de México en el año 2016-2017. Se determinó el semivariograma experimental para ajustarse a un modelo teórico (esférico, exponencial o gaussiano) a través de los programas Variowin 2.2, su ajuste se validó con el método de validación cruzada y se obtuvieron los mapas de agregación de la plaga a través del Krigeado ordinario con el programa Surfer 9.0. Los resultados demostraron que las poblaciones de huevos de B. cockerelli presentan una distribución de tipo agregada, que fue corroborada por los mapas de densidad. Las infestaciones no se presentaron en el 100% de la superficie de las parcelas experimentales, lo cual resulta interesante para dirigir las medidas de control sobre áreas específicas de infestación.
Corrupción, Gobernabilidad y Crecimiento Económico. Un estudio empírico
Authors: Hernández Verme Paula Lourdes , Herrera Madrid Paulina
Published: October 2019

En este trabajo se estudia la causalidad, en el sentido de Pearl (2003, 2009), bidireccional entre Corrupción y Crecimiento Económico, utilizando información de 41 países para el periodo 1996-2010 y de 34 países para el periodo 1999-2010. Se aplica el Modelo de Ecuaciones Simultáneas para datos panel, utilizando variables de control económicas, institucionales y de gobernabilidad. Estimaciones en trabajos previos sugieren una relación negativa y estadísticamente significativa entre el grado de corrupción y el nivel de crecimiento económico de cada país, pero no logran identificar si existe un efecto de retroalimentación, por lo que utilizamos el Método de Ecuaciones Simultáneas. Asimismo, incluimos el efecto de las variables de gobernabilidad sobre la corrupción. El análisis de los resultados indica que, efectivamente, economías con elevados niveles de corrupción y falta de gobernabilidad presentan también bajos niveles de crecimiento económico. Más aún, se demuestra que hay evidencia de la interrelación entre el nivel de crecimiento económico y el grado de corrupción.

Published: October 2019

The interaction of silver nanoparticles with Tomato seeds (Solanum Lycopersicum L.) was studied; the amount of silver uptake by tomato seeds was quantified by using flame atomic absorption. The absorption analysis was carried out according to the performance study of the method to estimate the detection and quantification limits as well as the accuracy. The seeds were exposed at different silver concentrations and different times. A simple method has been developed for the determination of silver content in aqueous matrices by acid digestion followed by atomic absorption spectroscopy flame; it was found that the acid digestion is efficient for extraction of the analyte in a single step. The limits of quantification achieved in the analytical method allow the determination of silver on plant tissue, the highest silver uptake in the tomato seeds was obtained with the treatment using the highest silver concentration (10 mM) and longer exposition time (48 h).

Published: October 2019

La fertilización con microorganismos benéficos es una alternativa para aumentar el crecimiento y la productividad de los cultivos como la albahaca (Ocimum basilicum L.). El objetivo de este estudio fue determinar el efecto de hongos micorrízicos arbusculares (HMA) y la bacteria marina Stenotrophomonas rhizophila sobre el crecimiento de albahaca var. Nufar. Adicionalmente, se determinó en la bacteria la actividad de la enzima desaminasa del ácido 1-aminociclopropano-1-carboxílico (ACC) y fijación biológica de nitrógeno (FBN). Posteriormente, plantas de albahaca fueron inoculadas con dos consorcios de HMA (ORECIB01 y SALCIB01) y la bacteria marina. Se cuantificó altura, longitud de tallo y raíz, área foliar, biomasa, clorofila, colonización micorrízica y población bacteriana. Los resultados muestran que la inoculación simultánea de ORECIB01 y bacteria promovieron significativamente todos los parámetros morfológicos y de clorofila en las plantas. La interacción HMA-bacteria incrementó la micorrización y la población bacteriana. La fertilización biológica de plantas de albahaca puede ser una opción viable en el manejo orgánico y sustentable del cultivo.
El manejo como herramienta para la conservación y aprovechamiento de la fauna silvestre: acceso a la sustentabilidad en México
Authors: Hernández-Silva Dante Alfredo , Pulido María Teresa , Zuria Iriana , Gallina Tessaro Sonia A. , Sánchez-Rojas Gerardo
Published: October 2019

El manejo de vida silvestre incluye todas aquellas acciones que se realizan para obtener beneficios ecológicos, socioculturales o económicos provenientes de la vida silvestre. En la actualidad, se plantea el manejo bajo un enfoque de sustentabilidad, por lo que resulta urgente reconciliar dos acciones que se consideraban en el pasado como incompatibles, la obtención de una rentabilidad económica de las actividades humanas y la preservación a largo plazo de la biodiversidad. Bajo la directriz de la sustentabilidad deberán de conjugarse a través de un manejo que logre según las necesidades mantener, aumentar, estabilizar o disminuir una población de vida silvestre de manera que estas acciones impacten en la conservación, control, reproducción o aprovechamiento sustentable fuera o dentro de su hábitat natural. El manejo adecuado de vida silvestre solo se consigue con la participación de los diferentes actores involucrados, quienes deberán adoptar una evaluación técnica-científica, tomando en cuenta el bienestar animal, aplicar conocimientos básicos y tradicionales y acatar la legislación vigente.

The Realization of the Bad Impact of Early Capitalism in Oscar Wilde’s “The Happy Prince”
Authors: Holis Nor , Asmarani Ratna
Published: October 2019

Living under feudalism and capitalism seems very good for those who were born from rich people. It is because they do not have to struggle of their life and would get everything as desire. Meanwhile, it is very hard for poor people because their live is worse and if they do not struggle of the life they might die. “The Happy Prince” is the story that shows how the feudalism and early capitalism work in the society. People live contradictory under those systems. Fortunately, since the capitalism applies, the poor people find new hope. Their laborpower is paid so that they are to feed themselves and the family. Besides, they work for the capitalists’ happiness. This new term of live is not a big different from feudal system. The payment for the poor who work is a very little difference that makes the poor happy. This research aims to describe how the feudalism and the early capitalism work in the short story. Using the sociological approach as to the evidences of the feudalism and the early capitalism system in the story is chosen to describe the impacts of those systems toward society. The result of this research shows that poor people accept the system of capitalism than the feudalism. It is because their labor-power is paid. This condition is different from previous system (feudalism) that makes poor people are getting worse because they must work freely.

Published: October 2019

Objective

Turner syndrome (TS) is characterized by the complete or partial loss of the second sex chromosome and associated with a wide range of clinical manifestations. We aimed to assess the medical care of adult patients with TS in Germany.

Design

Retrospective multicenter observational study.

Methods

Data were collected from medical records of 258 women with TS treated between 2001 and 2017 in five non-university endocrinologic centers in Germany.

Results

Mean age was 29.8 ± 11.6 years, mean height 152 ± 7.7 cm, and mean BMI 26.6 ± 6.3 kg/m2. The karyotype was known in 50% of patients. Information on cholesterol state, liver enzymes, and thyroid status was available in 81–98% of women with TS; autoimmune thyroiditis was diagnosed in 37%. Echocardiography was performed in 42% and cardiac MRI in 8.5%, resulting in a diagnosis of cardiovascular disorder in 28%. Data on growth hormone therapy were available for 40 patients (15%) and data concerning menarche in 157 patients (61%).

Conclusion

In 258 women with TS, retrospective analysis of healthcare data indicated that medical management was focused on endocrine manifestations. Further significant clinical features including cardiovascular disease, renal malformation, liver involvement, autoimmune diseases, hearing loss, and osteoporosis were only marginally if at all considered. Based on this evaluation and in accordance with recent guidelines, we compiled a documentation form facilitating the transition from pediatric to adult care and further medical management of TS patients. The foundation of Turner Centers in March 2019 will improve the treatment of TS women in Germany.

The Kighal Porphyry Cu–Mo Deposit, NW Iran: Insights into Origin and Evolution of the Mineralizing Fluids
Authors: Hassanpour S. , Rajabpour S.
Published: October 2019

—The Kighal porphyry Cu–Mo deposit, located at 46°42′36″ N and 38°37′06″ E, occurs 120 km north of Tabriz and 12 km north of Varzeghan in the Arasbaran magmatic belt, NW Iran. The geologic units in the Kighal area are Eocene and Oligocene volcanic rocks associated with Miocene intrusive and subvolcanic rocks. Quartz-monzonite porphyry in the Kighal area hosts porphyry style Cu–Mo mineralization consisting of four alteration zones (potassic, phyllic, argillic, and propylitic) and abundant quartz veinlets. Based on mineralogy and geochemistry data, the intrusive and subvolcanic rocks belong to quartz-diorite, diorite, and granite units with high-K calc-alkaline to calc-alkaline affinities. All samples are enriched in LILE and depleted in HFSE, pointing to a mantle magma source contamination with subducted oceanic-crust material. Three types of fluid inclusions are identified in quartz from different quartz-sulfide veinlets, including multiphase (LVS) and liquid-rich (LV) inclusions in the potassic zone, liquid-rich (LV) and vapor-rich (VL) inclusions in the phyllic zone, and liquid-rich (LV) inclusions in the silicic zone. Microthermometry studies showed that Th in multiphase fluid inclusions in the potassic zone varied from 265 to 450 °C and salinity, from 38 to 59 wt.% NaCl-equiv. These values are higher than those of two-phase fluid inclusions in the phyllic zone (Th of 163 to 466 °C and salinity of 0.3 to 11 wt.% NaCl-equiv.). The calculated δ18OH2O and δDH2O values in biotite, sericite, and quartz from potassic, phyllic, and silicic zones showed that it is predominantly magmatic water with a lesser amount of meteoric water that is responsible for mineralization in the potassic zone. Light δDH2O values of biotite in the potassic zone suggest a magma degassing process and/or a change in the fluid composition with magmatic water influx to a hydrothermal system.

Published: October 2019

OBJECTIVES:

We measured behavioral, quality of life (QoL), and functional status outcomes for 6-year-old children with hypoplastic left heart syndrome enrolled in the Single Ventricle Reconstruction Trial. We sought to compare these outcomes with those in the normative population and to analyze risk factors for worse outcomes within the single-ventricle group.

METHODS:

Parent-response instruments included the Vineland Adaptive Behavior Scales, Second Edition (Vineland-II) (primary outcome), Behavior Assessment System for Children 2, Pediatric Quality of Life Inventory 4.0, and other measures of QoL and functional status. We compared subjects with those in the normative sample using 1-sample Wilcoxon rank tests and assessed outcome predictors using multivariable regression.

RESULTS:

Of 325 eligible patients, 250 (77%) participated. Compared with population norms, participants had lower scores on the Vineland-II motor skills domain (90 ± 17 vs 100 ± 15; P < .001), with 11% scoring >2 SDs below the normative mean. On nearly all major domains, more study subjects (3.3%–19.7%) scored outside the normal range than anticipated for the general population. Independent risk factors for lower Vineland-II scores included perioperative extracorporeal membrane oxygenation, male sex, use of regional cerebral perfusion, catheterization after stage 2 operation, visual problems, seizure history, and more complications after 2 years (R2 = 0.32). Independent predictors of worse Behavior Assessment System for Children 2 (R2 = 0.07–0.20) and Pediatric Quality of Life Inventory 4.0 (R2 = 0.17–0.25) domain scores also included sociodemographic factors and measures of morbidity and/or greater course complexity.

CONCLUSIONS:

At 6 years, children with hypoplastic left heart syndrome had difficulty in areas of adaptive behavior, behavioral symptoms, QoL, and functional status. Principal risks for adverse outcomes include sociodemographic factors and measures of greater course complexity. However, models reveal less than one-third of outcome variance.
Osteoporosis of the Jaws and its Diagnostic Methods: Review of the Literature
Authors: Rocha Claros Mg Jacqueline Jovana
Published: October 2019

Osteoporosis is a chronic, silent, multifactorial and metabolic bone disease characterized by low bone mineral density and altered micro architecture, presenting a high fracture rate with minimal trauma or without trauma (hip, spine and forearms). Osteoporosis can occur in both sexes and in all ages; mainly considered a problem for postmenopausal women, with higher risk of fracture over 50 years old. This increases the morbidity, mortality and costs of the health system, considering it a significant public health issue. Healthy bone has equilibrium characteristics between bone formation by osteoblasts and bone resorption by osteoclasts. In osteoporosis this balance is altered, showing a greater tendency to resorption. The most important risk factors for osteoporosis are age, sex, genetic factors, early menopause, inadequate calcium intake, lack of exercise, alcoholism, and smoking; it can also be associated with some endocrine diseases, such as hyperparathyroidism, kidney failure chronic, liver disease, malabsorption and drugs, including oral glucocorticoids. The objective of this bibliographic review is to provide updated and specific information about osteoporosis in the jaws and its diagnostic methods, which allow the dentist and radiologist to recognize, prevent and / or refer to the specialist indicated cases that may arise with this condition.
Gendered and genderless constructions of religious identity in a Charismatic community of practice
Authors: Tuplano Ma. Vera Infante , Gustilo Leah , Correo Cynthia Borromeo
Published: October 2019

A plethora of studies that account for the differential use of language by men and women have explained why such differences exist from the standpoint of Deficit, Dominance and Difference models, emphasising male and female dichotomy or male domination over women. The present study aims at filling a gap in language and gender research by underpinning its analysis with a social constructionist paradigm which views language and its interaction with the community of practice (CofP) as the conduits in shaping identity and by locating the context of the study inside a religious CofP. Our analyses indicated that the members of a Charismatic religious community share common selfpresentation strategies when constructing their identities, rejecting the dualism that distinguishes male and female language. Both males and females in our study have the same tendencies in using Supplication, Intimidation, Admitting Mistakes, Apology and Excuse in the narration of their Old life and Exemplification and Burnishing in the characterisation of their New life. However, the same respondents also exhibited differential use of tactics that also bolster previous findings on gender order. The interlocking relations of language, identity (religious or social) and gender are mutually constructed and negotiated constantly in a community of practice which is influenced by cultural and religious practices.
‘I went to debutante school’
Authors: Shrikant Natasha , Marshall Dana
Published: October 2019

This paper analyses how one United States Southern female professional, Suellen, navigates the ‘double bind’ of being a culturally appropriate woman and culturally appropriate leader. Data analysed include a two-hour audiorecorded meeting from eight months of fieldwork with a Texas organisation. Analysis illustrates how Suellen enacts a Southern feminine identity when implicitly claiming authority on business matters and overtly claims her identity as a woman when explicitly claiming authority on women-related matters. These findings address debates among language and gender scholars about determining the relevance of gender to interaction. We show how gender is a culturally specific identity that participants simultaneously implicitly perform and explicitly construct in ways that meet institutional goals. Multiple approaches to language and gender are not in contention but rather complement one another to highlight the variety of resources participants can use when making gender relevant in interaction to meet institutional goals.
Novel alternative for the purification of kaolin by plant acid extracts
Authors: Olvera Venegas Patricia Nayeli , Villanueva Ibáñez Maricela , Flores González Marco Antonio , Reyes Aparicio Ariadna Itzel , Hernández Pérez María de los Ángeles
Published: October 2019

Clay minerals of great purity are scarce; such is the case of kaolin. Many methods currently used for its purification damage some characteristics of industrial interest of the clay mineral, and these methods are aggressive to the environment. For this reason, in this work, the purification of kaolin was carried out using the extracts of Citrus latifolia, Citrus aurantifolia, Opuntia joconostle and Allium sativum. The clay mineral was sifted to obtain a size of ≤38 μm. The liquor obtained after the dissolution of iron was characterized by atomic absorption spectroscopy. A percentage of removal of 91·43% was obtained for C. aurantifolia, 88·76% for C. latifolia, 67·84% for O. joconostle and 62·19% for A. sativum. The clay mineral was characterized before and after iron dissolution by energy-dispersive X-ray spectroscopy, scanning electron microscopy, Fourier transform infrared spectroscopy and X-ray diffraction. Plant acid extracts are a viable alternative for the removal of iron from kaolin. The obtained iron removal percentages were higher in comparison with those obtained by other methods currently in use, making this alternative simple and eco-friendly and producing no damage to the morphology of the clay. The percentages of elimination of iron obtained by this method provide acceptable kaolin for use in industries.
The bond property between concrete confined with textile-reinforced concrete and a steel bar
Authors: Jing Lei , Yin Shi-ping , Lv Heng-lin
Published: October 2019

In this paper, based on pull-out test results, the influence of the number of chloride wetting–drying cycles, concrete strength, cover thickness, steel bar diameter and number of textile layers used in the textile-reinforced concrete (TRC) confinement on the bond property between concrete and a steel bar is analysed. Furthermore, a bond strength model is developed and the confinement effect of TRC and fibre-reinforced polymer is compared. The study results show that the ultimate bond strength decreased slightly as the number of chloride wetting–drying cycles increased, because only a slight corrosion of the steel bars was observed in this test. The influence of the concrete strength on the ultimate bond strength of the unconfined specimens was significantly higher than that of the TRC-confined specimens, and the improvement effect of TRC confinement was more pronounced for the low-strength concrete. Compared with the concrete strength, the cover thickness and steel bar diameter had less influence on the ultimate bond strength. With an increase in the number of textile layers, the ultimate bond strength improved significantly, and TRC confinement showed a better ability to limit the crack development in the confined specimens in which more than one layer of textile was used.
Nickel oxide nanoparticles on the surface of the gallium arsenide nanocluster structure
Authors: Iskakova Kulpash , Akhmaltdinov Rif
Published: October 2019

This paper describes how the efficiency of the active element of a solar cell of gallium arsenide (GaAs) is increased by nickel oxide nanoparticles. The simulated structure of a semiconductor GaAs compound with a diamond-like lattice shows how the intersphere space grid is generated based on the face-centered cubic lattice motif. A theoretically determined optimal concentration of nanoparticles on the surface and the corresponding values of the experimental data are shown. Studies of the electronic structure on small GaAs clusters at n = 18 correspond to a minimum value of –19·238 eV and a maximum value of –5·606 eV for the state n = 0, –2·99 eV and 20·232 eV for the state n = 1, –0·693 eV and –0·03 eV for the state n = 2, –0·16 eV and –2·646 × 10–4 eV for the state n = 3, respectively. Peaks in the spectra sequentially observed within these limits coincide with the maximum value of the wave vector. Spectral variations, depending on the size of the interspheric space and the number of ion cores, correlate well with changes in densities. The electron density structure of GaAs has a complex structure. The maximum probability of finding is concentrated near four Ga ions. When approaching the center, the electron density changes in a wave-like fashion with a small maximum in the center. The results of the calculations show that gallium atoms in clusters with a higher binding energy, as a rule, are located on the surface or in the places of atomic edges, since the atoms of the faces are less consistent. Arsenic atoms are located in the center, surrounded by gallium atoms.
Social Media Content in Journalists Articles
Authors: Belenko Victoria , Zyryanov Victor
Published: October 2019

The Internet anonymity for a long time made it difficult for journalists to use the content presented in it. Now, thanks to the convergence of the "virtual" personality and the "real" one, this problem has been mitigated. Journalists begin to perceive social networks as sources of information, and they start to interpret what is published in them as reliable data or public statements. This research shows the extent of penetration of social networks information to the media, characterizes structural-functional features of this recent journalism tool. This work shows how often, when and for which purposes Media uses the social networks and how does this situation influences the articles. The continuous selection from RIA Novosti, Life.ru and Lenta.ru (683 articles) allowed us to examine features of representation of information from social networks. It was found that journalists use social media materials to confirm some fact or position of a person, as an information guide, they borrow there photos or videos, and, analyzing the comments, reproduce the "opinion of the audience". In general, it is shown that social networks have already secured the place of information providers for the media. The media began to trust this information, learned how to work with it, to process it for certain genres. There are even special software tools that allow Internet media to integrate very organically posts from social networks into their pages with publications when creating a site. The identical virtual personality of a real person, created now in social media, increasingly brings communication within the network closer to communication in real life, which expands the professional journalistic toolkit.

Semiotics as an Instrumental Analysis System in the Communication Practice of Premium Brands
Authors: Makeeva Maria
Published: October 2019

The article reviews fundamentally new processes in the field of premium branding which formed under the influence of the global trend of instrumentalization of art. As the consumer community becomes more and more targeted, the mass market model and traditional channels of communication are not sufficient in modern conditions; brands need to develop such communication models that would consistently affect all target audiences, but at the same time point to the specific audience loyal to the brand. There is a need to create new specific communication technologies that develop the brand in the context of the intangible economy and provide an emotional component in relations with the audience groups, bring a symbolic value. In this connection the research of this article is based on the new phenomenon ALBC (Arts-Luxury Brand Collaborations) - which is new in the premium sphere, and expressed in the cooperation of premium brands with contemporary artists in creating both a new luxury product and a creative platform for positioning. In order to gain an insight into the essence of the specific language of the ALBC communication model and read the coded messages - whether it be an advertising mini-movie, a store, a showcase, a collection, a separate model, etc. - it is necessary to determine its essence and understand the internal structure. The new model of communication involves defining new parameters for the brand. The article uses the traditional methods used in semiotics which are presented in the works of F. de Saussure, C. Moriss, C. Pearce, J. Lotman, etc. The purpose of the article is to analyze the ALBC media-communication model in premium brands promoting using some theoretical and methodological fundamentals of semiotics, and to offer an instrumental model of the ALBC code as an integrated model. According to the hypothesis of this article which formed on the theory of connotative and denotative messages of R. Barth, the ALBC model seems to be an independent discourse that incorporates elements from other discourses, in particular from the discourse of art, and forms its code system. The method of "mediarcheological excavations", actively used in media studies, helped to analyze the structure of the ALBC model, to illustrate and analyze the process of discursive layering of historical realities in the context of the proposed model, as well as to shape the author's definition of the ALBC code. There is a conclusion that the ALBC code represents a complex structure of a connotative message based on an unmotivated symbolic sign, has the character of polysemy and possesses such system characteristics as a migratory character, an evolutionary form; is formed owing to discursive layering of historical realities; the goal of creating a new code is an outspoken marketing interest - to attract the consumer, to interest the young audience, to immerse in the brand's atmosphere.
Strategies of Personal Account Promotion on Instagram
Authors: Zyryanov Bogdan
Published: October 2019

In the article, an Instagram page is considered as part of mass communications which brings money and other benefits to its holder. Deep interviews with Russian Instagram bloggers confirmed our hypothesis: each account represents a separate medium with its own information and advertising policy. The article explores such parameters as content planning, interaction with subscribers, advertisers and other bloggers, as well as ROI assessment via the Statistics tool. Promotion in Instagram is achieved through the observance of aesthetic norms and thematic and stylistic unity. In-depth interviews with domestic bloggers confirmed our hypothesis: each separate account is actually a mini-media with its information and advertising policies. The author of the blog thus functions as a curator, or "issuing editor": there is a careful selection of photos that correspond to the concept, themes, and most importantly-the style of the account. There is an important difference between a business SM manager and an independent Instagram blogger: while the former makes content plans for approval with the client, the latter does not rely on long-term planning; instead, he/she procures posts the night before or creates them just before publication. This achieves the effect of sincerity, the sense of "being in the moment", which subscribers appreciate. Graphic content plays the primary role in the promotion of the profile. Additional coverage is provided by hashtags, interaction with subscribers, participation in the #sfs flashmob and symmetric content exchange between bloggers of the same level. It is possible to measure ROI via independent audit by means of the "Stats" tool built into Instagram. This allows to better understand the audience and adjust communication to expand influence. Cooperation with brands starts on average from 10K subscribers. The blogger presents his/her audience and proposes a joint project. The success of advertising placement largely depends on how well the ad post corresponds with the established aesthetics of the profile. Affiliate publications are placed in the main profile, as well as in Stories-a special section with photos and 15-second videos, which are deleted 24 hours after the publication. Reach of such publications is lower, but they are better perceived by subscribers, and placement in Stories costs advertisers cheaper than in the grid. The greatest coverage comes from getting a post featured in the "Trends" section; however, this is regulated by proprietary algorithms within Instagram, and is not possible to predict.

The article reveals the concept of public health, Institute of public health, explains why and how these concepts have entered international practice, and describes the situation in Russia. However, the focus of interest of researchers is the media attitude to public health. The authors of the article consider historical and theoretical background, which show that the media community of the country is able to act as a stakeholder, i.e. one of the direct participants of the formation of the Institute of public health as a system of interdepartmental, inter-group, interpersonal interaction based on the care of human health, and recognized as the most important social value. In this regard, special attention is paid to the priority tasks of journalists and bloggers, who will apply a new approach to the coverage of health, significantly expanding the usual problems. The article considers competitive programming activities as a suitable for present conditions means of organization of information support of events in this area and offers a matrix for the development of such programs. Another important means for organizing information processes, according to the authors, lies within the principles of reflecting the formation of the Institute of public health in the media publications. They offer five such principles for consideration: actual reliability, integrity and logical literacy of interpretation, balance of rational and emotional arguments of the author's position, visual recognition of publications on the subject of public health as a single cycle, stability of periodicity and structure of publications on the topic of public health.
Formation and Transformation of the Concept Russia in the Picture of the World of Modern American Students
Authors: Strelchuk Elena , Lonskaia Anna
Published: October 2019

The media are one of the significant factors that influence the formation of the world views of a particular person and the nation as a whole. Analysis of Russian-American relations from the 19th century up to nowadays makes it possible to judge the ambiguous attitude of Americans towards Russia through the media. The purpose of the article is to analyze the concept of Russia, its formation and transformation in the world views of modern American students on the basis of the frame approach. Various research methods (associative experiment, questionnaire, observation, complex, conceptual analysis, etc.) made it possible to distinguish two basic components of the Russia concept: Russia: before arrival and Russia: after arrival. In this connection, the content of the concept is different. Russia: after arrival consists of more metaphorical models and subframes than the concept Russia: Before Arrival. Such metaphor models as Russia - Religion, Russia - Food as well as the sub-frames physiological characteristics and mental characteristics included in the metaphor model Russia - The Man: anthropomorphic characteristics demonstrate the extension of the concept Russia: after arrival. As a result of the research, it was concluded that the concept of Russia: Before Arrival was formed under the influence of American media, whose main task was to cover mainly political events. The concept Russia: after arrival has changed: the study of the Russian language, as well as the familiarity of American students with the culture, history, traditions of the Russian people in the conditions of the Russian-speaking environment had a positive impact. The concept of Russia was rather a bright phenomenon filled with expressive, memorable traits and reflecting the American students persuasion that the two peoples separated by political contradictions have similarities and it is necessary to build the intercultural communication between the Russians and Americans in the multipolar world.
Judicial Review of the Legislative Process in Lesotho: Lessons from South Africa
Authors: 'Nyane Hoolo
Published: October 2019

The Constitution of Lesotho has a supremacy clause which ordinarily empowers the judiciary to review the actions of other branches of government. However, the judiciary in Lesotho seems to treat the legislative process with deference. This deference seems to be based on the old common law notion of the non-intervention of the judiciary in the legislative process. The notion has its roots in the British constitutional system. The Constitution of Lesotho, 1993 has even protected this doctrine through a constitutional ouster clause in section 80(5). The main question which this paper seeks to answer is whether indeed the common law notion of non-intervention in the legislative process is part of the constitutional law of Lesotho. In the end, the paper uses South African jurisprudence on the review of the legislative process to make a case that Lesotho can use the supremacy clause in the constitution and other constitutional doctrines such as the rule of law and legality to break with the common law notion of non-interventionism.
