A carne é um ótimo meio para a multiplicação de microorganismos e pode ser contaminada durante a aquisição da matéria prima, no processamento, armazenamento, transporte ou preparo. Rotineiramente centenas de placas de petri são utilizadas para a inspeção dos produtos alimentícios em laboratórios onde técnicos realizam a contagem das unidades formadoras de colônias. Como toda tarefa repetitiva, esta análise é susceptível à falhas humanas e exige uma quantia razoável de tempo. O objetivo deste trabalho foi desenvolver um algorítmo simples que não dependa de iluminação controlada, para realizar a contagem automática de unidades formadoras de colônias obtidas da incubação de amostras de contra filé. O algoritmo foi desenvolvido com o uso da linguagem Python v2.7 e a biblioteca OpenCV v3.0. A média de erro na contagem automática foi de 7,7% para as 40 placas processadas. Não foram encontradas contaminações significativas nos cortes bovinos analisados. O tempo médio empregado na contagem das UFCs pelo método visual e o automático foi de 44,6 e 2,07 segundos, respectivamente. O sistema desenvolvido apresentou resultados iniciais promissores. A iluminação não homogênea, o formato irregular e o contato entre colônias tem forte impacto no resultado das análises.

A utilização de dispositivos GNSS (Global Navigation Satellite System) para aplicação em atividades agrícolas, construção civil, aeronáutica e em automóveis vem ganhando cada vez mais destaque no cenário global. O uso desta tecnologia possibilita uma abordagem mais precisa e prática para os problemas encontrados pela humanidade. Para isso, a acurácia na medição da posição é de suma importância para uma gestão precisa das atividades. Com o intuito de comparar a precisão de diferentes tipos de receptores (GPS de Navegação em dispositivo próprio e em Smartphone e GPS topográfico), este trabalho consistiu na realização de três diferentes testes de acurácia de posicionamento (testes de altura, alinhamento e área) frente a uma medição de referência (trena), para com isso avaliar a aplicabilidade destes dispositivos em operações que demandam alta precisão. Concluiu-se que o GPS Topográfico obteve o melhor desempenho dentro os demais dispositivos nos testes. No entanto, nenhum dos receptores apresentou resultados satisfatórios para serem utilizados em operações que demandam alta precisão.

Published: June 2018

Optimization of methods for diagnostics and prediction of lung cancer, which occupies a leading position in the structure of oncological diseases, still remains an important task. In this study we have investigated the level of cytokines and acute-phase proteins in saliva of patients with lung cancer in dependence on the tumor size, and distant and regional metastasis. The case-control study included 121 patients, which were divided into 3 groups: the main group (patients with diagnosed lung cancer, n=70), the reference group (patients with non-malignant lung pathologies, n=12) and the control group (conditionally healthy individuals, n=39). All participants answered the questionnaire, underwent biochemical study of saliva and histological verification of the diagnosis. The content of IL-2 and IL-4 in saliva reduced in both lung cancer and inflammatory lung diseases, whereas the levels of IL-18, IL-8 and TNF-a decreasd in lung cancer and increased in non-malignant pathologies. Tumor progression was accompanied by an increase in the level of proinflammatory cytokines (IL-6, IL-8, IL-18, TNF-a), whereas the levels of IL-2, IL-4 and IL-10 decreased. Although saliva levels of C-reactive protein and tumor markers increased in lung cancer they did reach the level of statistical significance as compared with the reference group. Thus, with the only exception of IL-2 and IL-4, the saliva levels of cytokines in lung cancer patients insignificantly differ from the control group. However, the recognzied dynamics of the saliva cytokines level in patients with distant and regional metastasis opens the prospect of using these parameters for monitoring the treatment and controlling relapse occurrence.
A neuro-scientific approach to environment care
Authors: Puigdefábregas J. , Pérez-García M.
Published: June 2018

Grass-root feedback to public agencies’ policies for coping with global change threats is poor and reactive. Concurrently, human population becomes more urban, isolated from nature and unable to take personal decisions about it. Therefore, helping societal involvement and proactive behavior towards nature is a crucial challenge nowadays. This paper intends to explore the role of emotions in support of a positive interaction in human/environment systems, to assess their evolutionary changes and ways to eventually readdress its trend. For that purpose, the latest neuroscientific findings are applied to disentangle the nature impact on the human emotional system by comparing the present people’s attitudes to those from pre-agrarian cultures. This knowledge allows drawing guidelines to improve people´s concern to care for the environment.

La evaluación por competencias en educación física y el proceso de construcción de una rúbrica
Authors: Zapatero Ayuso Jorge Agustín , González Rivera María Dolores , Campos Izquierdo Antonio
Published: June 2018

Desde su incorporación a la normativa del sistema educativo español, las competencias se han convertido en un referente curricular, planteándose como los elementos que vertebran la evaluación y promoción (Ley Orgánica 8/2013, de 9 de diciembre, para la mejora de la calidad educativa). El hecho de incluir las competencias en el currículo exigió cambios en el desempeño docente, cuya labor debe procurar el desarrollo de una evaluación formativa y basada en competencias. No obstante, los estudios evidencian que estas evaluaciones no llegan a desarrollarse en el día a día de los centros educativos. Se advierte de la falta de preparación del profesorado, el escaso asesoramiento de las administraciones y la falta de acuerdos en los centros educativos. En este contexto, este estudio pretende ser una guía para que el profesorado en general, y en particular el de Educación Física, pueda plantear y llevar a cabo evaluaciones por competencias mediante el diseño de rúbricas que valoren el grado de adquisición de las competencias en sus alumnos.

Authors: García-Gómez Soledad , Ordóñez-Sierra Rosario , Izquierdo Chaparro Rosario
Published: June 2018

Las familias del alumnado de formación profesional apenas son objeto de estudio por parte de la investigación educativa. Pasar de la educación secundaria obligatoria a la formación profesional es una transición en la cual “desaparecen” las familias de los estudiantes. Ser mayores de 16 años, la finalización de la escolaridad obligatoria y la elección de una vía profesionalizante en lugar del bachillerato, son factores que parecen alejar al sistema educativo de las familias y viceversa. Así pues, el objetivo de este trabajo ha sido explorar mediante una metodología cualitativa cuáles son los rasgos descriptivos básicos de familias de este tipo de alumnado. Han participado veinte familias de zonas rurales de la provincia de Sevilla. El análisis de contenido de las entrevistas semiestructuradas destaca la preeminencia de la familia nuclear tradicional, el bajo nivel de cualificación académica y laboral de estas madres y estos padres, así como unas condiciones económicas precarias. Destaca el interés que manifiestan por la formación de sus descendientes y por su futuro laboral. Como principal conclusión resaltar la necesidad de avanzar en esta línea de investigación desde una perspectiva inclusiva con este colectivo de familias, lo cual tendrá repercusiones positivas en el alumnado de formación profesional.

Published: June 2018

La actual evidencia científica presenta diversos posicionamientos en la definición de los niveles de estrés en función del género y su influencia en el rendimiento académico. Los objetivos del estudio son: a) examinar las diferencias de género en el nivel de estrés académico, de estresores académicos y de estrategias de afrontamiento en estudiantes universitarios; b) evaluar la relación entre los niveles de estrés y el rendimiento académico. Participaron 162 estudiantes universitarios del Grado en Educación Primaria con una edad media de 23.7 (DE=5.68). El instrumento de medida utilizado fue el Inventario SISCO del estrés académico. También se recogió la nota media de expediente académico de los estudios de grado. Los principales resultados fueron: 1) El 96.1% de las mujeres y el 88.2% de los hombres presentan niveles de estrés académico; 2) “Las evaluaciones de los profesores” y “el tipo de trabajo que piden los profesores” son los estímulos estresores que muestran una diferencia estadísticamente significativa, percibiendo mayor estrés las mujeres, (p=0.008, p=0.005; respectivamente); 3) Las mujeres utilizan más “la ventilación y confidencias” como estrategia de afrontamiento, respecto al género masculino (p=0.001); 4) No se halló relación entre estrés y rendimiento académico.

Las conclusiones de este estudio apuntan a fortalecer la educación y la formación en el emprendimiento, especialmente en el ámbito familiar, para crear, educar, construir y producir futuros emprendedores.
MATHEMATICAL CALCULATION AND EXPERIMENTAL INVESTIGATION OF EXPANDED PERLITE BASED HEAT INSULATION MATERIALS’ THERMAL CONDUCTIVITY VALUES
Authors: AĞBULUT Ü.
Published: June 2018

Thermal resistance can be
increased by using proper heat insulation materials. Traditional heat
insulation materials do not stand all desired properties. Thus, developing new
heat insulation materials is very important. In this study, expanded perlite
based heat insulation material was developed as an alternative to the
traditional insulation materials. The composition of the developed material was
designed and prepared using the theoretical thermal conductivity prediction
models. The prepared material was molded in a rectangular shape panel. Thermal
conductivities of panels were measured experimentally and the results were
compared with the   calculated results.
Also, the results showed that the developed panels can be used for heat
insulation applications. On the other hand, the closest model to the
experimental results is the parallel model whose average deviation is 4.22%
while the farthest model is the Cheng and Vachon model whose average deviation
is 12.43%. It is obtained that parallel and series models are generally in good
agreement with the experimental results. Nevertheless, it is seen some
deviations between experimental and theoretical calculation results.  The theoretical prediction models do not
include any processing conditions such as molding and curing. It is thought
that these deviations have originated because of the missing processing
parameters in theoretical prediction models. As a result of experimental
studies, the lowest thermal conductivity value of expanded perlite based panels
was obtained 43.5 mW/m.K. Consequently, the heat transfer coefficient of the
panels containing expanded perlite can be calculated nearly by the parallel
method.

Effect of Quebracho Bark on the Properties of Opaque Glazes
Authors: KÖSEOĞLU Kemal , CENGİZLER Hakan , İSRAEL İSRAİL Lina
Published: June 2018

In this work, the effect of
quebracho bark (QB) on the physical and chemical properties of opaque
glaze/glazes (OG) was investigated. 
Various ratios (0.25-10 weight percent) of quebracho bark were
incorporated into the glazes to obtain experimental glaze recipes and melting
temperatures of the glaze compositions were calculated through the fluxing
factors of the oxides present in the glazes. Thereafter, the glaze compositions
were fired at the calculated temperature value of 1100°C. Viscosity, thixotropy
and pH tests were conducted on OG and OG+QB glaze suspensions. Standard coloring
analyses, crazing resistance, impact resistance, resistance to acid and
alkalis, water absorption, firing strength, and surface hardness tests were
conducted. After establishing the Seger formulas, surface tensions of the
glazes were calculated by making use of the molar surface tension factors of
the oxides already present in the glaze compositions at the same sintering
temperature of 1100°C. QB additions decreased the viscosity and standard
thixotropy values of the OG and had no significant effect on the pH of the OG
slurry. On the other hand, QB additions caused an increase in the whiteness (opacity)
of the OG. No crazing and impact fractures were observed on the glaze surfaces.
Furthermore, the glaze surfaces showed good resistance to acid and alkalis. On
QB incorporation, water absorption decreased in all the experimental glazes.
Firing strength and surface hardness increased with increasing QB content.
According to the experimental results, 5 weight percent (wt. %) QB addition was
found to be the optimum amount.
Prediction of Methane, Water and Ice Properties for Numerical Gas Hydrate Simulations
Authors: Merey Şükrü
Published: June 2018

Gas
hydrates are considered as near-future potential energy resources. Due to the lack
of gas production data from gas hydrate reservoirs, numerical simulations are
very important to make production predictions for both experimental studies and
field production trials. Methane and water flow together when gas hydrates
dissociate inside the sediments. Hence, many parameters of methane and water
such as density, viscosity, enthalpy, internal energy and thermal conductivity
should be calculated at different pressure and temperature values during
non-isothermal numerical gas production simulations from gas hydrate
reservoirs. As a solid phase, ice might exist in the pores due to the
endothermic dissociation of gas hydrates. For this reason, water, methane, ice
properties as a function of temperature and pressure are estimated by the Matlab
codes written in this study: waterprop.m, gasprop.m, and iceprop.m. Density,
viscosity, enthalpy, internal energy and thermal conductivity of water and
methane calculated with the Matlab codes in this study, National Institute of
Standards and Technology were compared, and the reliability of waterprop.m,
gasprop.m and iceprop.m was proved.

This paper examines and presents a simple
computational Monte Carlo algorithm to determine the total, intrinsic and
geometric efficiencies of  NaI(Tl) gamma
ray detectors for gamma rays emitted by isotropic radiating (point) sources
with several energies in the range of 150-3000 keV. The code was used to compute
efficiency values for various source-to-detector distances for each studied
gamma ray energy. The comparisons with the data reported in the literature
indicated that the present algorithm is useful in efficiency calculations for
any source-detector and geometry configuration.

Authors: Başpınar Yücel , Kotmakçı Mustafa , Öztürk İsmail
Published: June 2018

Phytosphingosine
(PS) is a natural antimicrobial ingredient present in the mammalian stratum
corneum of the skin. The skin surface is the first line defense system against
microbial colonization and infections. The aim of this study was to investigate
in vitro antimicrobial effects of PS
and PS-hydrochloride (PSHCl) nanoemulsion (NE) formulations and solutions
against bacteria and fungi. Minimum inhibitory concentrations (MICs) of the
PS-NE and PSHCl-NE formulations and PS/PSHCl solutions were determined by
microdilution method against Gram-positive/Gram-negative bacteria and yeasts.
Inhibitory effects were also examined by disc diffusion method and inhibition
zone diameters were determined. PS/PSHCl solutions and PS-NE/PSHCl-NE
formulations were prepared in different conditions. Physicochemical properties
of the NEs were characterized and antimicrobial activities were evaluated. In
this study we reported that the PS and PSHCl and NEs had variable antimicrobial
activities for a variety of Gram-positive bacteria (MIC range 1 µg/ml to 1024
µg/ml), Gram-negative bacteria (MIC range 8 µg/ml to 1024 µg/ml) and Candida
strains (MIC range 8 µg/ml to 512 µg/ml). Sphingolipids are part of the natural
defense system of the body. We demonstrated that PS and PSHCl solutions and NEs
have broad antimicrobial activity against bacteria and yeasts. In addition, the
newly developed formulations may have potential for prophylactic and
therapeutic intervention in infections.

Possible Effect of Stratospheric QBO on The Ionospheric E-Region Current Densities
Authors: SAĞIR Selçuk , ÖZCAN Osman
Published: June 2018

It is known that ionospheric winds cause the ions to drift in the geomagnetic field. This drift set up a current which produces ground-level geomagnetic field variations.  In this study, the relationship between stratospheric QBO and the ionospheric E- region current densities (Jx and Jy) for low latitudes (01.22 N, 103.55 E) have been statistically investigated using the multiple regression model.  Also the effect of F10.7 solar flux index was included in the investigation.  As a result of the investigation using the multiple regression model, it was determine that an increase/a decrease of 1 s.f.u in the F10.7 solar flux caused an increase/a decrease of 1.5x10-2 A/km and 2.5x10-2 A/km on Jx and Jy current density, respectively. On the other hand, an increase/ a decrease of 1 m / s in the QBO caused a decrease/ an increase of 3x10-3 A/km and 4x10-3 A/km on Jx and Jy current densities, respectively.

Published: June 2018

A plasma is a

medium containing a large number of charged particle interactions. For this reason, it is common and appropriate to

examine the plasma in terms of kinetic theory. In this context, the collision

dynamics of the ‘O+ + N2

→ NO+ + N’ reaction for geomagnetically quiet day (04/09/2017)

and disturbed day (08/09/2017) were calculated for ionospheric altitudes with

the help of kinetic theory. As a result of the calculation, it was seen that

the mean free path values were less on the disturbed day, as expected. The

total collisions number was seen to reach maximum at the height of hmF2 on both

quiet and disturbed days, and the disturbed day values were greater. It was

seen that the collision frequency decreased exponentially with altitude.

Una visión crítica al derecho urbanístico cubano. inconsistencias y contradicciones del modelo actual
Authors: Martín López Alexey , Jurado Almonte José Manuel
Published: June 2018

A enero de 2018, Cuba no ha tenido una ley de ordenación urbana que regule los usos del suelo y la actuación de la Administración pública en esa materia. En este contexto, en el país rige un modelo administrativo y económico altamente centralizado. Además, el poder público detenta la mayor parte de los recursos económicos con los que cuenta el país. Esta investigación tiene como objetivo abordar el funcionamiento del sistema y del modelo cubano de ordenamiento territorial desde una perspectiva interdisciplinaria, que incluye consideraciones de ciencia política, economía y derecho urbano. Los resultados del estudio permiten sostener que el ordenamiento jurídico cubano no brinda el soporte adecuado para regular la actividad de la Administración en el ámbito urbanístico.
Los planes de ordenamiento territorial departamental: beneficios y riesgos de un instrumento clave para la ordenación del territorio en Colombia
Authors: Santaella Quintero Héctor
Published: June 2018

Con base en las facultades que les reconoce la Ley 1454 de 2011 a los departamentos, con el apoyo del Gobierno nacional, estas entidades territoriales se preparan para la expedición de planes departamentales de ordenamiento territorial. Con ello se agrega una pieza fundamental a nuestro esquema de ordenación del territorio, hasta hoy construido a partir de una visión esencialmente municipal. No obstante, pese a la importancia de este paso (por los beneficios que comporta), la total ausencia de un régimen legal que enmarque y oriente el ejercicio de esta competencia origina riesgos notables para la legalidad de las actuaciones que se desarrollan, así como para la autonomía local y la participación ciudadana en la toma de estas decisiones. El artículo explora estos asuntos.
Seguridad ciudadana en Bogotá. Análisis del presupuesto y la eficiencia en el gasto local 2011-2016
Authors: Granados Becerra Juan Carlos
Published: June 2018

En Bogotá, como en otras ciudades, la seguridad ciudadana se constituye en uno de los tópicos que puede llegar a generar mayor preocupación en los habitantes y, por tanto, en la Administración distrital. Para algunos autores, la lógica de las políticas públicas indica que a mayor prioridad en la agenda, mayor asignación de recursos, por ello, en este artículo se cuestiona y compara el comportamiento de la asignación presupuestal para seguridad ciudadana con otros sectores de intervención local en el Distrito y, adicionalmente, se revisa el nivel de eficiencia de la inversión pública en el mismo ítem, es decir, si efectivamente en la ciudad, la disminución de homicidios, las lesiones personales o violencia interpersonal, y hurtos a personas, establecimientos, residencias y vehículos, es directamente proporcional al presupuesto destinado para seguridad ciudadana.
El soft law en derecho administrativo y su control judicial en Colombia
Authors: Martínez Jurado Darío
Published: June 2018

El soft law administrativo o el uso del derecho blando es una realidad en la práctica de la Administración que facilita el logro de los fines del Estado posmoderno. Sin embargo, también es factible que en esa zona de producción normativa abundante se soslayen principios, garantías fundamentales y derechos de los destinatarios de las normas o terceros interesados. Este documento muestra la necesidad de que estos instrumentos estén alineados al principio de juricidad, ya que su procedimiento de emisión es informal y, en la escena jurídica, se les considera como carentes de efectos obligatorios y, por ende, de control judicial.
La revisión de oficio de disposiciones y actos administrativos nulos de pleno derecho en España

Published: June 2018

El 2 de octubre de 2016, un año después de su publicación en el Boletín Oficial del Estado, entraron en vigor la Ley del Procedimiento Administrativo Común de las Administraciones públicas (LPAC) y la Ley de Régimen Jurídico del Sector Público (LRJSP). Ambas leyes vinieron a derogar y sustituir el Régimen Jurídico de las Administraciones Públicas y del Procedimiento Administrativo Común (LRJPAC). En concreto, la LPAC puso fin a la regulación hasta ahora existente en España en materia de revisión de oficio de actos y disposiciones nulos, y en su lugar ha establecido una regulación nueva, aunque no novedosa, que será objeto de estudio en las próximas páginas.
Mecanismo de extensión de la jurisprudencia del Consejo de Estado a terceros como escenario de activismo judicial dialógico
Authors: Beltrán Acosta Elizabeth
Published: June 2018

El mecanismo de extensión de la jurisprudencia del Consejo de Estado a terceros, más que un trámite que contribuye a la descongestión judicial o a reafirmar la teoría de la fuerza vinculante de los precedentes, es expresión del principio de colaboración armónica entre las ramas ejecutiva y judicial del poder público. Esta investigación busca mostrar que esta figura no solo reafirma el papel unificador del Consejo de Estado y su intervención en el procedimiento administrativo que involucra la aplicación de sus sentencias de unificación, sino que además permite un diálogo entre estas dos ramas del poder público (activismo judicial dialógico), necesario para asegurar la seguridad jurídica y el respeto del principio de igualdad.
Urgentes reformas al sistema de organización del contencioso administrativo nicaragüense
Authors: Arrién Somarriba Juan Bautista
Published: June 2018

La justicia administrativa nicaragüense se caracteriza por su centralización orgánica y territorial, lo que puede provocar un trato desigual en el acceso a la misma, demoras injustificadas y la transgresión al debido proceso, al no tener el recurrente derecho a un recurso de alzada, ante un juzgador independiente e imparcial del que emitió la sentencia. Además, su personal no se rige por los procedimientos de la carrera judicial, sino por un sistema de nombramientos directos, sin criterios claros de especialización y con riesgos de politización. A partir de un examen de la reciente reforma constitucional nicaragüense que aprueba la descentralización de la justicia administrativa, se muestra la necesidad de incorporar cambios y regular su estructura, y la manera como se escoge a su personal persiste.
Sustainable Local Development, Corporate Social Responsibility and Social Entrepreneurship

Published: June 2018

The world is becoming increasingly globalized, and all its changes directly affect the regions and their people. It is therefore necessary to diagnose and evaluate decision-making in the business world, in order to analyze its effect in the environment where it will be applied as such, we start from the existing relationship between corporate social responsibility, sustainable local development and social entrepreneurship within the territorial scope. Human beings are embedded in a reality in which the new rules of the game predominate these rules are defined by a few transnational companies and, in one way or another, they participate in the production of most of the goods and services consumed on a daily basis. Accordingly, a behavior that goes beyond the politically and legislatively correct is required, a behavior that encourages the endogenous development of the territories, delving into the necessary promotion of innovation as a variable of long-term sustainability.

El método del autor consiste en recurrir a lecturas humanísticas del texto (Carteromaco, Canter, Lipsio) a fin de encontrar una traducción adecuada de los tres términos utilizados por Aristides para definir la alteridad en Roma: παράνοια, δυστυχία y κακοδαιμονία. Del mismo modo, el autor reconstruye las ideas y las fuentes que subyacen bajo estos términos. La recuperación de la erudición humanística se convierte así en un procedimiento útil para la moderna investigación sobre textos clásicos.
Measuring Functionality of the Low-cost Housing for the Urban Poor: Unheard Voices of Asansol City, West Bengal
Authors: Manna Papiya
Published: June 2018

In inclusive development paradigm, every person has the right to access basic amenities, and housing is one of them. Urban governance has to provide shelter to its citizens, and when the poor occupy a sizable portion of this population, the roles of urban governance become more crucial. A significant portion of the city dwellers in-migrate into the city from the surrounding areas. They are mainly unskilled or semi-skilled people, who have migrated into the cities in search of livelihood and settle down in places which gradually transforms into slums. In India, public housing as a part of poverty alleviation, aims to provide shelter as well as a comfortable environment to the beneficiaries. The key objectives of this research are to find out the role of the local government of Asansol, West Bengal in providing housing to the landless poor and to examine the responses from the housing dwellers. Mixed method approach has been applied here, and people's responses have been recorded with a semi-structured questionnaire based on purposive sampling technique. However, it has been found that the ability to access essential services is not the same for all sections of the society. This signals that when the questions of accessing resources are linked to the poor, either their voices fail to reach the appropriate places or they remain unheard in most spheres. Thus, the gap between the government and the poor are widening regarding the provision of essential services, accountability and regularity of monitoring of the public housing environment. As a result, the functionality of the low-cost housing is yet to achieve the desired goal of inclusivity in Asansol. Urban space is still exclusive for poor and vulnerable.
The Oral Folk Literature of the Ancient Meiteis of Manipur: An Analysis of its Cultural Significance
Authors: Caesar Thounaojam , Sanasam Reena
Published: June 2018

Oral narratives are the earliest forms of storytelling as they exist in every culture as a part of religious rituals, folk music and songs. They include ritual texts, curative chants, epic poems, musical genres, folk tales, creation stories, songs, myths, spells, legends, proverbs, riddles, tongue twisters, word games, recitations and other narratives not recorded in writing. With the invention of writing, the ancient forms of oral narratives have undergone a lot of changes and have become valuable works of literature. However, the charm of oral narratives often told by improvisation and even gestures as a part of tradition cannot be transcribed into literature. As oral stories are brought down from generation to generation and are committed only to the memory, the various stages of the growth of such narratives give an account of the culture of the people. These are the sources of popular entertainment and are closely associated with festivals and religious ceremonies. At present, our society feels the need to safeguard and protect these indigenous forms of arts from the danger of extinction due to the impacts of globalisation and commercial entertainments. The exploration of the meanings and themes of ancient narratives, in a broader social context, and the significant role of the variant folklore genres in maintaining collective wisdom, national identity, solidarity and traditional moral values are points of great concern in this study.
Comparative Analysis of Educational Attainment among Different Social Groups in Some Selected Mouzas of Saltora C.D. Block of Bankura District, West Bengal, India: An Empirical Study
Authors: Maji Krishnendu , Sarkar Sumana
Published: June 2018

Education plays multifarious instrumental roles in the realisation of certain ends both at individual and societal level. A large number of research works carried out in and outside India have identified and established a whole range of externalities produced by education such as raising human capital beyond individual level. Despite debates on economic returns to education, most scholars agreed about the positive impact of education upon economic return. The present study has mainly focused on a comparative analysis in attainment of education among three different social groups that is, scheduled castes (SC), scheduled tribes (ST) and other non-scheduled castes at school level. This is a micro-level empirical study focusing on one of the least developed Community Development Block (CDB) of Bankura district in West Bengal. The analysis of the study reveals that disadvantaged social groupsâ€”SCs and STs are the marginalised depressed classes experiencing high level of educational deprivation compared to that of other communities. One has to note that affiliation to a particular caste can no longer be tagged as a sole determinant of relative backwardness. So what is called for is a careful stratification of the community on the basis of socio-economic attributes so as to diagnose the problem of the community at hand properly. The study uses logistic regression as an analytical tool to probe net effects of the predictor variables including castes on enrolment and discontinuation rates for the study area as a whole as well as for boys and girls separately. It is important to note that when other variables are controlled, the net effect of caste factor becomes statistically inconsequential either on enrolment or on discontinuation or dropouts. Rather, it is the combination of several socio-economic factors that are taken together which pulls down the enrolment of ST and SC children vis-a-vis those belonging to others non-scheduled castes.
Culture of Friendship Among the Apatanis of Arunachal Pradesh
Authors: Hilaly Sarah
Published: June 2018

The Apatanis of Ziro Valley are a tribe in Arunachal Pradesh. The community is known for their sedentary agriculture among all dry farming communities in this state. It is sustained without the use of draught power and an indigenously developed irrigation system. Inhabiting a small sequestered plateau, their agriculture represents the most efficient in terms of energy use. Among the traditional institutions of the Apatani is the labour gang known as the Pataň. Its composition is based largely on village friendship cutting across genders that are equally represented, in addition to kinship-based unity. This aspect is evident in a tradition during Myoko festival where friends visit across villages to renew their ties. The festival and its associated rituals also assign a special position to friendship. The paper seeks to explore the ritual aspect of friendship and its relevance of friendship in the circulation of labour for sedentary agriculture.

The USA and Tuvan People’s Republic: issues of book exchange (on documents of the State Archives of the Republic of Tuva)
Authors: Maadyr M. S.
Published: June 2018

The article examines the attempts of the Library of Congress of USA to establish contacts for book exchange with the Tuvan People's Republic. This fact took place in the second half of the 30s in the XX century. However, the Tuvan side, as evidenced by the analysis of well-known archival documents, did not provide any answers. Such attitude of the Tuvan People's Republic authority is explained by a number of reasons. One of them was a geopolitical situation both at the global and regional levels. Complicated circumstances were observed in the Tuvan People's Republic by that time, under which conditions it was not appropriate to react to «imperialist states» appeals, in particular, on book exchange at the international level.
Carbon nanostructures: scientometric analysis for 2000-2015 (Part 3)
Authors: Terekhov A. I.
Published: June 2018

The article presents a scientometric analysis of the development of the carbon nanotechnology (NT) direction for 2000-2015 with the participation of 30 most active countries. It shows shifting the world research center to the Asian region, both on volume and quality indicators. Using the concept of a national research portfolio gives deep characteristics of different countries behavior in the course of scientific rivalry. Due to the strong skewness of the citation distributions, preference is given to the percentile-based indicators, such as: the contribution of a country to the world top-10% (top-1%) of the most highly cited publications, the share of such publications in the country's total output, the highly cited papers index, etc. Relying on them, the author fully discloses the scientific «offensive» of the «newcomer» countries on the «incumbents» ones (e.g. China on the USA, South Korea on Germany, Iran on Russia), the phenomenon of Singapore as an effective producer of highly cited publications on the carbon nanostructures, and international co-authorship in the top-1% segment of the most cited articles. Russia's positions are studied in detail, the main domestic research participants are established, and based on bibliometric criteria the center of scientific excellence in the field of graphene is identified. The paper characterizes the supporting role of a number of national science foundations in the NT carbon direction development using data of WoS. The author used the Science Citation Index Expanded database for the initial bibliographic sampling; information of science foundations of Russia and the USA, as well as patent organizations of Russia (Rospatent) and the world (WIPO) for additional comparison.
