El docente de Educación Superior: su práctica analizada desde las creencias del proceso de enseñanza-aprendizaje
Authors: Navarrete Sánchez Enrique , Farfán García María del Carmen , Castillo De la Rosa Ernestina
Published: November 2019

El docente tiene un papel fundamental en el proceso de enseñanza; esta investigación se centra en el docente de Educación Superior, el cual ha tenido en la última década una serie de cambios en sus actividades, originada por las reestructuraciones de los Programas educativos y de los Planes de estudio. La transformación que puede observarse con mayor atención es la forma de concebirse la enseñanza, ya que antes el docente de este nivel educativo se contrataba para impartir docencia en su carácter de especialista de una área disciplinar, actualmente debe enseñar basado en un modelo educativo que privilegia las competencias de su disciplina, por lo tanto, el docente debe tener una serie de conocimientos que le permitan comprender su práctica educativa y determinar las estrategias didácticas que cumplan con el objetivo de su Programa, considerando la responsabilidad y el compromiso social en la formación de profesionistas que contribuyan de manera significativa al desarrollo del país y a la transformación justa de la sociedad. El objetivo del estudio fue analizar la práctica docente de un grupo de profesores de Nivel Superior de la Universidad Autónoma del Estado de México (UAE- Méx.), desde las creencias del proceso enseñanza-aprendizaje. Se aplicó el Inventario de Perspectivas de Enseñanza cuyo objetivo consiste en identificar qué es lo que creen, se proponen lograr y hacen los profesores cuando enseñan. Se aplicó a una muestra de 284 docentes. Los resultados indican que existe coherencia entre lo que el profesor cree, las intenciones que tiene y las acciones del proceso de enseñanza aprendizaje.
Desarrollo socioemocional en niños mexicanos: un estudio narrativo sobre la migración
Authors: Pérez Padilla María de la Luz , Olmos Ríos Felipe , Solorio Núñez María Teresa
Published: November 2019

Ante el fenómeno de la migración, tanto los familiares que se van como los que se quedan, se ven influenciados de alguna manera. Los niños como actores sociales, también viven y observan la migración directa e indirectamente. Ellos de acuerdo al contexto y a su propio proceso psico-evolutivo tienen una manera de narrar lo que saben y viven. La presente investigación hace un acercamiento a estos procesos socioemocionales a través de la narrativa y el dibujo de 653 niños de 3º a 6º de primaria, de los estados de Zacatecas, Michoacán, Hidalgo, Jalisco y Yucatán.  Se utilizó la investigación narrativa en donde ellos dibujaban su interpretación de la migración y relataban una historia al respecto. Se analizó la información con categorías preestablecidas y emergentes, encontrando que los niños expresan principalmente las emociones de tristeza y felicidad, emociones que están asociadas a situaciones sociales donde hay peligro y amenaza ante la migración y donde se puede triunfar al vencer obstáculos y al lograr el objetivo de migrar. Finalmente, se constató que estos niños tienen una consciencia social de otro tanto de su dolor, alegría como de las injusticias vividas.
variante del indianismo latinoamericano: el Tabaré de Juan Zorrilla de San Martín
Authors: Campa Mada Roberto
Published: November 2019

Este ensayo postula la especificidad de Tabaré (1888) de Juan Zorrilla de San Martín, en el contexto del indianismo hispanoamericano. Frente al "indio" estilizado y heroico del romanticismo de otras regiones, el Cono Sur traza la figura de un salvaje pendenciero y reacio a la civilización. En la encrucijada de estas dos tradiciones surge Tabaré, que recoge tópicos del romanticismo rioplatense (como el de los malones y el de la cautiva, en el marco de la dicotomía civilización/barbarie) para contribuir a la construcción ideológica de una nación uruguaya que busca legitimar sus raíces en un imaginario pasado indígena de tintes heroicos.
diablo de lo sublime. Preciosismo y clasicismo en la poética revolucionaria de Jorge Cuesta
Authors: Fernández Mora Vicente de Jesús
Published: November 2019

"El diablo en poesía" es un pequeño texto escrito por Jorge Cuesta en 1934 que tiene como excusa el comentario de la poesía de su amigo Xavier Villaurrutia. El artículo, en que puede verse un seguimiento de la ofensiva contra el nacionalismo que había emprendido durante el desarrollo de la famosa polémica sobre literatura y nacionalismo de dos años antes, fue publicado en el diario El Universal. En él nuestro autor arroja unas cuantas ideas fundamentales para entender su poética, siguiendo la estrategia de arrogarse el atributo de revolucionario para su personal forma de entender el arte. Jorge Cuesta se vincula a la tradición poética que surge con la lectura que hacen los franceses de la teoría poética de Edgar Allan Poe y que aúna al anhelo de Absoluto, procedente del romanticismo, en el contexto de una moderna sociedad desacralizada, otros elementos de sesgo desrromantizado como el concebir la práctica poética como un ejercicio cuasi científico, dotado de premeditación y cálculo. A partir de estas premisas, Cuesta desarrolla una muy personal teoría poética que resignifica términos de la tradición (clasicismo, romanticismo y preciosismo) en favor de la defensa de una forma de arte purista que estaban practicando él mismo y sus amigos del grupo Contemporáneos.
A quién miramos sin saber por qué: Juliana los mira de Evelio Rosero
Authors: González Echeverry Angela M.
Published: November 2019

El presente artículo propone la lectura de Juliana los mira, novela publicada en 1987 por el escritor colombiano Evelio Rosero, como bisagra entre dos discursos en tensión: la igualdad como derecho fundamental en la Constitución de Colombia y las prácticas culturales contemporáneas, para entender hacia dónde apunta la retórica de género en Colombia hoy día. Para este análisis se toma en cuenta el erotismo poético de los sentidos en la construcción de la identidad de género de la protagonista de la novela. Juliana los mira crea un espacio narrativo idóneo para la fragmentación, la duda y la exploración de las identidades de género, cuya consecuencia es la posible reformulación poder de lo corpóreo y del erotismo como fuentes fundamentales tanto de la narración como de la identidad. El artículo se acerca a la realidad sociopolítica del país por medio de dos eventos fundamentales en los cuales se aspira a defi nir y limitar el alcance del derecho a la igualdad. Se enuncian las interferencias sociales y culturales que permiten volver sobre la retórica de género, para comprender la dirección de este derecho fundamental en el contexto actual.
Efecto vudú: posmodernidad y la disolución de fronteras espacio-temporales en la narrativa fantástica mexicana de inicios del siglo XXI
Authors: Torres Mojica Tarik
Published: November 2019

La realidad global de inicios del siglo XXI nos muestra un espacio cambiante, de entrecruces de bienes culturales, cosmovisiones y lenguajes. Este entorno suscita cambios en la forma de vida y, entre otros aspectos, también en las artes, incluyendo la literatura. La cultura global se manifiesta en la producción literaria en México no solo por los temas que aborda, sino también por el modo en que se singulariza la experiencia humana ante un entorno que cambia constantemente y en el que nociones como certeza y linealidad histórica se han sometido a tensión; en suma, en el que diversos marcos de referencia construidos por la Modernidad han entrado en crisis. Así, se observa en la literatura mexicana el desarrollo de formas discursivas como la policíaca, la novela negra, el horror y la ciencia ficción, que históricamente han cargado sobre sí la sospecha de ser expresiones menores, de poca valía estética y, más aun, de ser ajenas a la tradición cultural nacional. En el presente artículo se hace una aproximación a la novela Efecto vudú de Edgar Omar Avilés, una obra construida con base en la hibridación textual, que discurre en la fragmentariedad y lo fantástico para desarrollar una historia en la que las nociones de tiempo, espacio, mito, magia y ciencia ficción se entremezclan. Para abordar esta obra se recurre primordialmente a la propuesta teórica sobre lo fantástico de Omar Nieto en Teoría general de lo fantástico.
poética disidente de Abigael Bohórquez
Authors: Rosado Marrero Juan Rogelio
Published: November 2019

Hablar de la poesía de Abigael Bohórquez es hablar de una obra centrada en la lucha política contra el discurso “heteronormativo”, el cual ha sido impuesto por las acciones “biopolíticas” que han llevado a cabo las distintas instituciones gubernamentales. Esta constante regulación sexual que se le hace al sujeto es lo que provoca el rechazo colectivo a todas esas prácticas erótico-afectivas que se alejan de la “norma” establecida. Por consiguiente, este trabajo examina la manera en la cual Abigael Bohórquez va constituyendo un sujeto lírico que cuestiona la visión “heteronormativa”, así como los procesos de “normativización” que se le han realizado a los sectores homosexuales; logrando así una “visibilización” tanto de las prácticas sexuales alternativas (en este caso, las relaciones homosexuales) como de los propios sujetos disidentes que han sido marginados a las periferias de las esferas políticas y sociales. Para ello, nos centraremos en los poemarios Digo lo que amo (1976) y Poesida (1996), debido a que estos nos permiten develar tanto las acciones políticas realizadas por Abigael Bohórquez como el discurso disidente que fue construyendo a lo largo de su obra poética. De tal forma que partiremos de un análisis textual a una contextualización de los poemarios mismos con el fi n de presentar ese cambio de paradigma que se da en su producción literaria: de una poesía homoerótica confesional (centrada más que nada en la descripción personal de la vida de los sujetos líricos) a una poesía de testimonio homosexual (cuyo principal objetivo es la denuncia política de los sectores marginales).
determinantes del yo lírico en las Rimas (1609) de Lope de Vega
Authors: Avilés Icedo César
Published: November 2019

El artículo intenta ofrecer una revisión sobre el yo enunciante de las Rimas de Lope de Vega. La base sobre la que se fundamenta esta reflexión es que el yo que aparece en los poemas es una construcción determinada principalmente por cuatro elementos: A) el referente cultural movilizado en los textos, B) las coordenadas espaciotemporales que sirven de contexto a la situación específica planteada en el poema, C) la postura del yo con respecto a dicho mundo y D) los distintos tonos que impregnan las composiciones. El análisis se concentra, entonces, en desentrañar cómo cada uno de estos elementos contribuye a la configuración de un yo textual. Además, se observa que el yo se concreta mediante la máscara y la pose, por las cuales el autor vela y devela su propia identidad.

Physical training of female students to do "push-ups"
Authors: Grinko L. K. , Pavlova I. V.
Published: November 2019

The article is devoted to the issues of designing a training programme for girls of a college age with the aim of improving strength endurance of all muscle groups involved in the “push-ups”, due to the standards of the GTO (“Ready for Labor and Defense”) programme, a national Russian sports and fitness system. The training programme is based on a non-conventional system of physical exercises – yoga. The basis of the methodology is compiled of gymnastic exercises (asanas) from different yoga schools (Hatha Yoga, Ashtanga Vinyasa Yoga, Iyen-gar Yoga), combined into sets. When building sets of exercises, the authors of the methodology considered general principles of yoga classes, paying particular attention to the technique of doing the exercises and working on the students' state-of-mind attitude. The programme is primarily aimed at female students who are not able to perform a single “push-up” exercise and is designed in such a way that as a result of performing a set of exercises students can master both the way to improve the state of necessary muscle groups and the technique of correct exercising and then perform “push-ups” at least a few times. Testing the methodology was carried out in the experimental group of female university students, where at the initial stage, 68% of girls were not able to perform a single control exercise. The results obtained from the pedagogical experiment allowed the authors to draw a conclusion about the effectiveness of the technique. The article is addressed primarily to physical education teachers, HEI students and school girls
Correlation between the person’s psychological features and hyperkinesia hormonal shifts
Authors: Rechkalov A. V. , Rechkalova O. L.
Published: November 2019

The purpose of this research was to study the correlation between the person’s psychological features and the level of hormones in athletes’ (exercising mostly in aerobic or anaerobic energy expenditure modes) blood serum. Athletes who exercised in different energy expenditure modes demonstrated different levels of unproductive neuropsychic stress: athletes exercising mostly in aerobic mode had low and medium levels of unproductive neuropsychic stress, those exercising mostly in anaerobic mode had medium and high stress levels in the majority of cases. Athletes with different levels of unproductive neuropsychic stress had significant differences in insulin, somatotropin, adrenocorticotropic hormone in their blood serum when having a physiological rest and after graded cycloergometric loads. The revealed shifts reflect peculiarities of recovery processes after muscle activity and indicate a great impact of a neuropsychic stress level on the organism’s adaptation to hyperkinesia
Estimates of Fast Radio Burst Dispersion Measures from Cosmological Simulations
Authors: Pol N. , Lam M. T. , McLaughlin M. A. , Lazio T. J. W. , Cordes J. M.
Published: November 2019

We calculate the dispersion measure (DM) contributed by the intergalactic medium (IGM) to the total measured DM for fast radio bursts (FRBs). We use the MareNostrum Instituto de Ciencias del Espacio (MICE) Onion Universe simulation to track the evolution of the dark matter particle density over a large range of redshifts. We convert this dark matter particle number density to the corresponding free electron density and then integrate it to find the DM as a function of redshift. This approach yields an intergalactic DM of

pc cm−3, with the large errors representative of the structure in the IGM. We place limits on the redshifts of the current population of observed FRBs. We also use our results to estimate the host galaxy contribution to the DM for the first repeater, FRB 121102, and show that the most probable host galaxy DM contribution,

pc cm−3, is consistent with the estimate made using the Balmer emission lines in the spectrum of the host galaxy,

pc cm−3. We also compare our predictions for the host galaxy contribution to the DM for the observations of FRB 180924 and FRB 190523, both of which have been localized to a host galaxy.

Enforcing social norms: Trust‐building and community enforcement
Authors: Deb Joyee , González-Díaz Julio
Published: November 2019

We study impersonal exchange and ask how agents can behave honestly in anonymous transactions without contracts. We analyze repeated anonymous random matching games, where agents observe only their own transactions. Little is known about cooperation in this setting beyond the prisoner's dilemma. We show that cooperation can be sustained quite generally, using community enforcement and “trust‐building.” The latter refers to an initial phase in which one community builds trust by not deviating despite a short‐run incentive to cheat; the other community reciprocates trust by not punishing deviations during this phase. Trust‐building is followed by cooperative play, sustained through community enforcement.

Reading is one of the basic skills that the students’ need to achieve, however, it is also one of the important competencies that is essential for reaching knowledge. Reading difficulty is a main problem that many teachers are coming across in their classrooms. Students’ with reading disabilities not only hinder the teachers’ flow of the lesson it also hinders the development of the students life skills. With the revolution of the technology in the 21ST century, assistive technologies are seen to be applied into the education settings at all levels and in all fields. Therefore, teachers are in need to know about the available technology and special technology programs in order to help their students facing difficulties in acquiring the necessary knowledge and skills. Technological enrichment of teachers' educational environment both facilitates and helps them to motivate students more easily. Technology support into the educational environments of the students with reading difficulties can improve their reading skills and enable them to succeed in reading and comprehending. The present study sought to determine the opinions of special education teachers’ regarding using assistive technology for students with reading difficulties. The research design is based on the qualitative case study design with purposeful sampling and easily accessible sampling technique. Researchers developed semi-structured interview form for data collection applied content analysis to analyze the collected data. The analysis of the study found that teacher opinions towards assistive technology usage for overcoming students’ reading difficulties are rather moderate. However, teachers’ general opinions about assistive technology utilization is promising and developing gradually.
Contraindre sans contraindre : du « client idéal » de l’école maternelle aux difficultés professionnelles enseignantes
Authors: Montmasson-Michel Fabienne
Published: November 2019

L’article analyse l’effet des définitions sociales de l’enfant et des normes pédagogiques sur les difficultés professionnelles enseignantes. Le cas de l’école maternelle et de l’acculturation langagière montre que les normes pédagogiques reposent sur un « client idéal » autonome politiquement (qui se tient tout seul) et cognitivement (qui apprend tout seul) : un idéal de classe bien éloigné d’une bonne partie des enfants réels. Le cas des activités orales montre comment l’idéal d’un enfant qui se tient tout seul conduit à des dispositifs pédagogiques faiblement efficaces et différenciateurs tout en générant des difficultés concrètes de mise en œuvre et des arrangements inconfortables. Le cas de l’alphabétisation montre comment l’idéal d’un enfant qui apprend tout seul produit des normes pédagogiques entretenant les difficultés scolaires tout en empêchant de penser et d’expérimenter des pratiques plus égalisatrices, susceptibles de résoudre certaines difficultés d’enseignement. Ces difficultés sont la marque d’un métier empêché.
Difficultés des enseignants lors de l’enseignement de questions socialement vives : quelle conceptualisation pour mieux les comprendre ?
Authors: Lipp Amélie
Published: November 2019

L’enseignement agricole est directement concerné par l’introduction de questions socialement vives (QSV) dans les curricula. Plusieurs recherches en didactique des QSV ont montré des difficultés récurrentes rencontrées par les enseignants face à ces objets d’enseignement-apprentissage. Toutefois, peu d’études ont circonscrit la notion de difficulté et les ont appréhendées en situation. Dans cet article, nous considérons que le concept de réel de l’activité développé en clinique de l’activité est porteur d’éléments de compréhension des difficultés des enseignants prenant en charge une QSV. Nous proposons ainsi d’articuler les cadres théoriques de la didactique des QSV et de la clinique de l’activité afin de mieux comprendre les conflits au cœur de l’activité d’enseignants. Une recherche menée auprès d’enseignants de zootechnie prenant en charge la question du bien-être animal en élevage montre que leurs difficultés sont intimement liées à des activités empêchées et contrariées.
Le travail en équipe en école primaire : une autonomie sous contrainte
Authors: Roaux Cécile
Published: November 2019

Cet article examine le paradoxe induit par « l’injonction » au travail en équipe au sein de l’école primaire française, qui reste à la fois sans un directeur statutairement reconnu, très centrée sur la classe et dans un système scolaire d’organisation encore pyramidale. Cette (pseudo) localisation du système scolaire est étudiée à la fois par le point de vue des acteurs au sommet de cette pyramide (Inspection générale, recteur, Direction Générale de l’enseignement scolaire, cabinet ministériel) et du point de vue des acteurs de terrain (hiérarchie intermédiaire, directeurs, enseignants). La méfiance que ce travail collectif « imposé » génère chez les enseignants, les détourne finalement d’un travail véritablement collaboratif et entraîne un repli sur soi et des conflits d’équipe, des tensions entre une « bureaucratie » délégitimée – mais de manière ambiguë – et une « anarchie » alimentée par les contradictions organisationnelles dans une période de changement de référentiel.
Enseigner dans le premier degré : système d’épreuves et répertoire de ressources
Authors: Bouchetal Thierry
Published: November 2019

Cet article étudie les difficultés enseignantes du premier degré à partir des notions d’épreuve et de ressource. Cela permet de révéler conjointement l’engagement des sujets dans leur travail et les éléments caractérisant les cadres et contextes sociaux de leur exercice professionnel. Nos données sont issues d’approches biographiques de professeurs des écoles en cours de carrière. L’analyse met au jour des trajectoires professionnelles façonnées par les conséquences d’un système d’épreuves articulé à un répertoire de ressources, dont nous pouvons rendre compte par une modélisation. Ainsi, nos résultats pointent cinq catégories d’épreuves en lien avec le projet d’enseigner et le quotidien de l’activité, auxquelles se rajoutent deux autres catégories d’épreuves qui témoignent de stratégies pour reconfigurer les parcours professionnels. Les ressources identifiées sont principalement issues de l’environnement de travail proche et des différentes strates du parcours personnel.
La présence des modèles contre-stéréotypiques chez les garçons étudiant le français au Cameroun
Authors: Valdin Teague Tsopgny Armel , Daouda Maingari , Annie Njopvoui Carole
Published: November 2019

La littérature sur les modèles contre-stéréotypiques en orientation scolaire s’est intéressée davantage au cas des filles dans les séries scientifiques, occultant la situation minoritaire des garçons dans les séries littéraires. La présente recherche étudie en contexte camerounais, l’effet de la présence de ces modèles à partir des enseignants du français, dans les études des garçons. Une collecte des données par questionnaire a été effectuée auprès de 110 étudiants inscrits au cycle licence en lettres modernes françaises (LMF), à l’université de Yaoundé I. Les résultats révèlent un effet mitigé des enseignants conformément aux hypothèses. En effet, les étudiants de LMF ont eu autant d’enseignants que d’enseignantes du français durant le cycle secondaire mais, ne perçoivent pas nécessairement un impact positif de la présence des enseignants sur leur réussite en français. Aussi, ils préfèrent moins étudier le français en présence des enseignants uniquement.

Authors: Bui Nhuong , Pham Long , Williamson Stan , Mohebbi Cyrus , Le Hanh
Published: November 2019

With mobile technologies' rapid development involving wireless networks and internet infrastructure, e-commerce has been evolving into a new, more significant phase: mobile commerce. Businesses throughout the world are highly motivated to invest in mobile commerce infrastructure and deploy their mobile commerce strategies as a source of sustainable competitive advantage to maintain existing and attract new customers. As probably the first systematic and comprehensive effort to date, this study analyzes the factors affecting customers' intention to use mobile commerce in Vietnam. The results show that perceived ease of use, perceived usefulness, variety of services, and trialability have both direct and indirect positive (via perceived usefulness) impacts on intention to use mobile commerce, while trust and social influence have indirect positive impacts on intention to use mobile commerce in Vietnam. Cost does not have any impact on intention to use mobile commerce in Vietnam. The results of this study are also compared with that of studies on mobile commerce conducted in China and Malaixia by Chong et al. Theoretical and practical implications, especially for helping businesses understand how to capture more customers in a rapidly developing country, Vietnam, are discussed.

Authors: Loganathan Jayakumar , Janakiraman S. , Dumka Ankur
Published: November 2019

In the future, the wireless network environment may suffer due to the unavailability of new spectrum bands. Cognitive radio research considers the current spectrum underutilization and provides a better model for the next-generation wireless environment. Since the implementation of the cognitive radio and its policies is a bigger challenge under static spectrum allocation, i.e., current wireless networks policy, many issues are in front of us to accomplish a better cognitive radio wireless environment. One of the major challenges is a secure transmission and efficient free channel selection. In this research, the authors considered an efficient free-channel selection scheme as objective and derived an integrated approach for free-channel selection with techniques, Dynamic weighted-VIKOR.
A Hybrid Approach to Retrieve Knowledge from a Document
Authors: Sahoo Deepak , Balabantaray Rakesh Chandra
Published: November 2019

The task of retrieving the theme of a document and presenting a shorter form compared to the original text to the user is a challenging assignment. In this article, a hybrid approach to extract knowledge from a text document is presented, in which three key sentence level relationships in association with the Markov clustering algorithm is used to cluster sentences in the document. After clustering, sentences are ranked in each cluster and the highest ranked sentences in each cluster are merged. In the end, to get the final theme of the document, the Gradient boosting technique XGboost is used to compress the newly generated sentence. The DUC-2002 data set is used to evaluate the proposed system and it has been observed that the performance of the proposed system is better than other existing systems.
A Bio-Inspired Algorithm for Symmetric Encryption
Authors: Benyahia Kadda , Mustapha Meftah , Abdelkrim Latreche
Published: November 2019

The exploits of the structure of the DNA to realize the cryptographic systems is a new direction. The security of data transfer is an important factor for data transmission. Cryptography is one of the methods that ensures this constraint by techniques for sending data confidentially. Harnessing the benefits of DNA to secure information content makes cryptography more efficient. In this article, the authors propose a symmetric cryptography system based on DNA called Stegano-DNA- which operates under two main modules: scrambling and encryption. In its scrambling phase, Stegano-DNA eliminates the logical order of the letters in the clear text by the use of boxes of substitutions, and in its encryption phase, looks for the short sequence DNA in the chromosome sequence and memorizes only the number of positions needed to optimize the encryption time than when memorizing all positions.
Application of Statistical Analysis Tools and Concepts to Big Data and Predictive Analytics to New Product Development
Authors: Galli Brian J.
Published: November 2019

In today's fiercely competitive environment, most companies face the pressure of shorter product life cycles. Therefore, if companies want to maintain a competitive advantage in the market, they need to keep innovating and developing new products. If not, then they will face difficulties in developing and expanding markets and may go out of business. New product development is the key content of enterprise research and development, and it is also one of the strategic cores for enterprise survival and development. The success of new product development plays a decisive role both in the development of the company and in maintaining a competitive advantage in the industry. Since the beginning of the 21st century, with the continuous innovation and development of Internet technology, the era of big data has arrived. In the era of big data, enterprises' decision-making for new product development no longer solely relies on the experience of decision-makers; it is based on the results of big data analysis for more accurate and effective decisions. In this thesis, the case analysis is mainly carried out with Company A as an example. Also, it mainly introduces the decision made by Company A in the actual operation of new product development, which is based on the results of big data analysis from decision-making to decision-making innovation. The choice of decision-making is described in detail. Through the introduction of the case, the impact of big data on the decision-making process for new product development was explored. In the era of big data, it provides a new theoretical approach to new product development decision-making.

Energy Efficient Clustering using Modified Multi-Hop Clustering
Authors: Vimala M.  , Ranjan Rajeev
Published: November 2019

In recent years, WSN has been widely used for building the decision support system (DSS) for solving the real-world problem. Moreover, out of several fields, one of the interesting fields that requires DSS is the monitoring of agriculture environment. Nowadays, monitoring an agricultural environment has become one of the essential fields. IoT has been one of the eminent technologies in recent years and WSN model has played the parallel role into it. These sensors have a limited power supply and this affects the efficiency of the algorithm. In the past, several methods have been proposed for efficient clustering, however, these methods fail to provide satisfactory accuracy. Hence, this article proposes an energy efficient methodology named modified multi-hop clustering (MMHC). This methodology takes three steps. The first step is assembling the nodes where the nodes are assembled, the second step couples the nodes, and the third step detects the redundant nodes and discard them. The main advantage of MMHC is that it can select multiple redundant nodes at one time and discard, and this makes the algorithm more fast and efficient. Moreover, in order to evaluate the algorithm several parameters have been considered, such as energy consumption, number of failed nodes, number of active nodes, and communication overhead.

Reflections on Schleiermacher’s God
Authors: Venter Rian
Published: November 2019

Schleiermacher’s approach to the doctrine of God has attracted interest in contemporary theological scholarship. The article tries to map the major features of his God-construal and a number of perspectives are highlighted. Attention is given to the general sentiments of his project, the history of interpretation, the question of a primary referent for ‘God’ and the centrality of causation, the role of structure in his Glaubenslehre and finally the attribute tradition and the doctrine of the Trinity. The second part of the article engages Schleiermacher’s interpretation from the developments in especially the Trinitarian Renaissance since the last part of the 20th century. A number of critical divergences are identified, for example, the preference given to plurality, greater appreciation for the immanent Trinity, a Trinitarian approach to the attributes and an expansive notion of the ‘practical’ implications of the Trinity. Critical questions about ‘Schleiermacher’s God’ are raised in the conclusion.

Abstract. The Arctic CLoud Observations Using airborne measurements during polar Day (ACLOUD) campaign was carried out north-west of Svalbard (Norway) between 23 May and 6 June 2017. The objective of ACLOUD was to study Arctic boundary layer and mid-level clouds and their role in Arctic amplification. Two research aircraft (Polar 5 and 6) jointly performed 22 research flights over the transition zone between open ocean and closed sea ice. Both aircraft were equipped with identical instrumentation for measurements of basic meteorological parameters, as well as for turbulent and radiative energy fluxes. In addition, on Polar 5 active and passive remote sensing instruments were installed, while Polar 6 operated in situ instruments to characterize cloud and aerosol particles as well as trace gases. A detailed overview of the specifications, data processing, and data quality is provided here. It is shown that the scientific analysis of the ACLOUD data benefits from the coordinated operation of both aircraft. By combining the cloud remote sensing techniques operated on Polar 5, the synergy of multi-instrument cloud retrieval is illustrated. The remote sensing methods were validated using truly collocated in situ and remote sensing observations. The data of identical instruments operated on both aircraft were merged to extend the spatial coverage of mean atmospheric quantities and turbulent and radiative flux measurement. Therefore, the data set of the ACLOUD campaign provides comprehensive in situ and remote sensing observations characterizing the cloudy Arctic atmosphere. All processed, calibrated, and validated data are published in the World Data Center PANGAEA as instrument-separated data subsets (Ehrlich et al., 2019b, https://doi.org/10.1594/PANGAEA.902603).
LOW-COST 4D BIM MODELLING: A COMPARISON BETWEEN FREECAD AND COMMERCIAL SOFTWARE
Authors: Di Donato D. , Abita M.
Published: November 2019

Abstract. The paper aims to investigate the potential inherent in a FOSS (Free and Open Source Software) approach for the 4D BIM modelling using Freecad. In order to reach this goal it shows a comparison of Freecad features with those of commercial software, considering the evaluation of the effective application of this Open Source software in the professional environment, and highlighting the progress in the FOSS BIM area, that still represents an unexplored study field if compared to the vast publications related to BIM modelling that occurred in the last two decades. To this end, the study has been carried out on a singular case study, a steel canopy which has been designed for the urban renewal of a public space in Teramo. Despite its size, the canopy required the definition of complex details. Its structural system has addressed the study to compare Freecad with some software dedicated to steel structures or particularly suitable for the modelling of this specific structural typology: Tekla Structures and Sketchup. Starting from a concise historical reconstruction of the FOSS spread, the paper introduces a brief overview of the potential of Freecad in terms of BIM modelling - also proposing an operational modality to facilitate the drawing of BIM elements within the software - and finally reaching to the examination of three simulations which has been carried. This comparison can be useful to establish the current state of development of Freecad in the field of 4D BIM.
3DMOVER 2.0 – LOW-COST APPLICATION FOR USABILITY TESTING OF 3D GEOVISUALISATIONS
Authors: Herman L.
Published: November 2019

Abstract. Three-dimensional (3D) visualisations of geospatial data have become very popular in the last years. Various applications and tools are based on interactive 3D geovisualisations. However, the user aspects of these 3D geovisualisations are not yet fully understood. While several studies have focused on how users work with these 3D geovisualisations, only few studies focus directly on interactive 3D geovisualisations and employ usability research methods like screen logging. This method enables the objective recording of movement in 3D virtual environments and of user interactions in general. Therefore, we created a web-based research tool: a 3D Movement and Interaction Recorder (3DmoveR). This tool is based on the user logging method, combined with a digital questionnaire and practical spatial tasks. The design and implementation of this tool follow the spiral model, and its current version is 2.0. It is implemented using open web technologies such as PHP, JavaScript, and the Three.js library. After building this tool, we verified it through load testing and a simple pilot test verifying accessibility. We continued to describe the first deployment of 3DmoveR 2.0 in a real user study. The future modifications and applications of 3DmoveR 2.0 are discussed in the conclusion section. Attention was paid to future deployment during user testing outside controlled (laboratory) conditions.

Abstract. Point cloud segmentation is a significant process to organise an unstructured point cloud. In this study, RGB point cloud was generated with the help of images acquired from an Unmanned Aerial Vehicle (UAV). A dense urban area was considered with varying planar features in the built-up environment along with buildings with different floors. Initially, using Cloth Simulation Filter (CSF) filter, the ground and the non-ground features in the Point Cloud Data (PCD) were segmented, with non-ground features comprising trees and buildings and ground features comprising roads, ground vegetation, and open land. Subsequently, using CANUPO classifier the trees and building points were classified. Noise filtering removed the points which have less density in clusters. Point cloud normals were generated for the building points. For segmentation building elements, normal vector components in different directions (X component, Y component and Z component) were used to segment out the facade, and the roof points of the buildings as the surface normals corresponding to the roof will have a higher contribution in the z component of the normal vector. The validation of the segmentation is done by comparing the results with manually identified roof points and façade points in the point cloud. Overall accuracies obtained for building roof and building facade segmentation are 90.86 % and 84.83 % respectively.
