Published: September 2018

Citizen science (CS) terms the active participation of the general public in scientific research activities. With increasing amounts of information generated by citizen scientists, best practices to go beyond science communication and publish these findings to the scientific community are needed. This letter is a synopsis of authors' personal experiences when publishing results from citizen science projects in peer-reviewed journals, as presented at the Austrian Citizen Science Conference 2018. Here, we address authors' selection criteria for publishing CS data in open-access, peer-reviewed scientific journals as well as barriers encountered during the publishing process. We also outline factors that influence the probability of publication using CS data, including 1) funding to cover publication costs; 2) quality, quantity and scientific novelty of CS data; 3) recommendations to acknowledge contributions of citizen scientists in scientific, peer-reviewed publications; 4) citizen scientists' preference of the hands-on experience over the product (publication) and 5) bias among scientists for certain data sources and the scientific jargon. These experiences show that addressing these barriers could greatly increase the rate of CS data included in scientific publications.
Norming and Calculation of Vapor Permeability of MultiLayer Building Enclosing Structures (Recommendations for Improving SP 50.13330.2012 "Thermal Protection of Buildings")
Authors: Perekhozhentsev Anatoly G.
Published: September 2018

The article considers the actual problem of the heat and moisture state of multi-layer enclosing structures of buildings. Therefore, it is very important to design a multilayer structure in such a way as to prevent condensation and moisture accumulation in the structure during the cold season. The article presents an original method for calculating the characteristics of individuallayers of a multilayer structure, in which only the condensation plane is allowed, so the structure works at thelimit, but moisture accumulation does not occur, since the required (normalized) resistance to vapor permeation is determined from the condition that the amount of vapor that enters the condensation plane is equal to the amount of vapor that comes out of it. A simple and reliable method for determining the temperature in the plane of possible condensation is given, then the position of this plane in the structure and the required resistance to vapor permeability of the entire structure are determined. The solution of this problem is reduced to solving a system of twolinear equations consisting of the sum of the thermal resistances of the layers and the resistances of the vapor permeation of these layers, equal to the corresponding standard values of heat transfer and vapor permeability. Twolayers are distinguished in the multilayer structure, one of which determines the heat-shielding properties of the enclosure, and the other regulates the diffusion of vapor through the structure. Solving the system of two equations with two unknowns, we determine the corresponding characteristics of theselayers, which provide the required heat-shielding properties and do not allow the accumulation of condensation moisture in the structure during the cold period of the year. The advantage of this method consists in the fact thatlayers in a multilayer structure are selected not intuitively, but by calculation for compliance with regulatory requirements.
Study of the Equilibrium Sorption Humidity of the Materials of the Enclosing Constructions of Buildings at a Temperature -20 °C
Authors: Kiselev Igor Y.
Published: September 2018

Equilibrium sorption humidity (further: sorption humidity) together with the thermal conductivity is the most important thermo-technical property of building materials, since itlargely determines the course of the process of heat- and moisture transfer through the enclosing constructions of buildings and, consequently, also the thermo-technical properties of these constructions. The isotherms of the absorption of vapors of water for foam concrete, cellular concrete, expanded-clay lightweight concrete, expanded-clay-pearlite lightweight concrete, expanded-shungizitlightweight concrete and arbolit were experimentally (by exiccator method) determined at temperatures -20, -10,4, +1,2, +20 and +35 °С. The analysis of the obtained results showed that the sorption humidity of all investigated materials increases with the temperature decrease from +35 °C to -10,4 °C. However, at a temperature -20 °С sorption humidity decreases, and what is more, that, it becomesless than the sorption humidity of these materials at a temperature of +20 °С. The reasons for the decrease of the sorption humidity of building materials at a temperature -20 °С in comparison with the values of this property at a temperature of +20 °C appears:

with the relative humidity of air φ< 80%: the sharp decrease of the mobility of water molecules of the first adsorbed monolayer at a certain temperature, which belongs to temperature range from -10,4 to -20 °С, and, as a result, a sharp increase of thelifetime of a water molecule in the first adsorbed monolayer;

with the relative humidity of air φ> 80% appears the second reason for the decrease of the equilibrium sorption humidity of building materials at a temperature -20 °C, namely, the freezing of some share of the capillary-condensed water and blocking by formed fixed ice the access of water vapor into the internal pore volume of material.
The Problem of Crisis in the Theory of Postmodernism
Authors: Khudin Alexey A.
Published: September 2018

The article is aimed at studying the theory of postmodernism, asLittLe studied and insufficiently disclosed in modern science, extremely complex and requiring detailed and in-depth analysis. The article sets the task to consider the problems of the crisis perception of the situation in postmodernism architecture period, existing in the regime of a multicultural polylogue. The issue of changing of architectural styles, reflecting global processes, is considered. The peculiarity of architectural thinking in the 1960-1990 period is studied from the point of view of changing of cultural paradigmatic attitudes. The author for the first time explores the causes of the emergence of a sense of crisis, as well as its effects in the form of growing reflection, irony, the formation of criticism and deconstruction, as derivatives of this state. Insufficient study of this problem requires a detailed consideration of the features of eschatological thinking in the cultural processes of the twentieth century and their reflection in the ideology of postmodernism, which is done by the author for the first time. The problem of confrontation between culture and civilization is analyzed, which is one of the little-studied phenomena of thinking in the second half of the twentieth century. The research touches upon the issues of values reassessment, the emergence of distrust to meta-narratives, skepticism to rationality, the defeat of the ideas of humanism, the death of culture, the existence in the process of global polemics, the loss of unambiguous self-identification and landmarks of contemporary human in the world. The author demonstrates the reasons for the emergence of pluralism, antiauthoritarianism, democracy, autoreflexia as ideologemes opposed to modernism. The article contains an examination of the emergence of neoromanticism, deconstruction, escapism as different directions in postmodernism.
"Model Cultural Village": Architectural Dreams and Reality of the 1920-1930s
Authors: Kosenkova Yuliya L.
Published: September 2018

The article is dedicated to the planning and development of the countryside in the 1920-1930s, both in the context of the rural social policy and in connection to the general orientation of Soviet town planning of this period. The idea of a "Model Cultural Village", which should've been shown to peasants as an example for imitation, was formed in the first post-revolutionary years. Depending on the changing construction policy of the State in the 1920-1930s, this idea was embodied in various projects, but all of them were far from the real situation in the countryside. In particular, attempts to create "exemplary" and then the "standard" projects of the planning of collective and state farm settlements, not based on the study of specific data, are considered.

The article shows the birth of scientific approach to the individual rural design based on pre-project studies in the second half of the 1930s. Such an approach was developed by the institutes of communal hygiene, but it did not manage to develop before the World War II. The social life basis in the countryside was unsustainable, and in the pre-war years the state policy regarding the planning of the countryside became much more strict. The struggle with the so-called "extravagances" began.

This trend was in contradiction with the slogan of "blurring the differences between urban areas and the countryside". The article shows the gradual simplification of the concept of "agro­town" - from agro-industrial plants, conceived in a big way in thelate 1920s, to a minimum equipping of the countryside. At the same time, the search for a visual image of the Soviet countryside was mainly reduced to competition projects of various "types" of clubs and community centers.

Authors: Demircan Semiye , Kahramanli Humar
Published: September 2018

ER (Emotion Recognition) from speech signals has been among the attractive subjects lately. As known feature extraction and feature selection are most important process steps in ER from speech signals. The aim of present study is to select the most relevant spectral feature subset. The proposed method is based on feature selection with optimization algorithm among the features obtained from speech signals. Firstly, MFCC (Mel-Frequency Cepstrum Coefficients) were extracted from the EmoDB. Several statistical values as maximum, minimum, mean, standard deviation, skewness, kurtosis and median were obtained from MFCC. The next process of study was feature selection which was performed in two stages: In the first stage ABM (Agent-Based Modelling) that is hardly applied to this area was applied to actual features. In the second stageOpt-aiNET optimization algorithm was applied in order to choose the agent group giving the best classification success. The last process of the study is classification. ANN (Artificial Neural Network) and 10 cross-validations were used for classification and evaluation. A narrow comprehension with three emotions was performed in the application. As a result, it was seen that the classification accuracy was rising after applying proposed method. The method was shown promising performance with spectral features.

Published: September 2018

Recommender Systems are valuable tools to deal with the problem of overloaded information faced by most of the users in case of making purchase decision to buy any item. Recommender systems are used to provide recommendations in many domains such as movies, books, digital equipment’s, etc. The massive collection of available books online presents a great challenge for users to select the relevant books that meet their preferences. Users usually read few pages or contents to decide whether to buy a certain book or not. Recommender systems provide different value addition factors such as similar user ratings, users past history, user profiles, etc. to facilitate the users in terms of providing relevant recommendations according to their preferences. Recommender systems are broadly categorized into content based approach and collaborative filtering approach. Content based or collaborative filtering approaches alone are not sufficient to provide most accurate and relevant recommendations under diverse scenarios. Therefore, hybrid approaches are also designed by combining the features of both the content based and collaborative filtering approaches to provide more relevant recommendations. This paper proposes an efficient hybrid recommendation scheme for mobile platform that includes the traits of content based and collaborative filtering approaches in addition of the context based approach that is included to provide the latest books recommendations to user.Objective and subjective evaluation measures are used to compute the performance of the proposed system. Experimental results are promising and signify the effectiveness of our proposed hybrid scheme in terms of most relevant and latest books recommendations.
Effect of Temperature and Time on Nickel Aluminide Coating Deposition
Authors: Chandio Ali Dad , Abro Shahid Hussain
Published: September 2018

The βNiAl coating was deposited onto Nickel based CMSX-4 superalloy by in-situ CVD (Chemical Vapor Deposition) method. Main focus of this contribution was to study the influence of aluminizing time and temperature on the microstructure and thickness of the coating; this was followed by examination by XRD (X-Ray Diffraction), electron microscope. Results suggest that an incremental variation in temperature alters the coating activities from HA (High Activity) to LA (Low Activity). This is exhibited by the resultant CT (Coating Thickness) since HA coatings are thicker than LA counterparts. The microstructure of the coating formed at low temperature (or HA ones) showed a large amount of α-Cr precipitates while one formed at high temperature (or LA ones) exhibited lower amounts of such precipitates. Moreover, incremental aluminizing time showed linear trend of CT at initial stage, thereafter (10 hrs) it leveled off. Whereas it does not affect microstructure of the coating
Implementation of Tuned Schema Merging Approach
Authors: Masood Nayyer , Jabeen Gul
Published: September 2018

Schema merging is a process of integrating multiple data sources into a GCS (Global Conceptual Schema). It is pivotal to various application domains, like data ware housing and multi-databases. Schema merging requires the identification of corresponding elements, which is done through schema matching process. In this process, corresponding elements across multiple data sources are identified after the comparison of these data sources with each other. In this way, for a given set of data sources and the correspondence between them, different possibilities for creating GCS can be achieved. In applications like multi-databases and data warehousing, new data sources keep joining in and GCS relations are usually expanded horizontally or vertically. Schema merging approaches usually expand GCS relations horizontally or vertically as new data sources join in. As a result of such expansions, an unbalanced GCS is created which either produces too much NULL values in response to global queries or a result of too many Joins causes poor query processing. In this paper, a novel approach, TuSMe (Tuned Schema Merging) technique is introduced to overcome the above mentioned issue via developing a balanced GCS, which will be able to control both vertical and horizontal expansion of GCS relations. The approach employs a weighting mechanism in which the weights are assigned to individual attributes of GCS. These weights reflect the connectedness of GCS attributes in accordance with the attributes of the principle data sources. Moreover, the overall strength of the GCS could be scrutinized by combining these weights. A prototype implementation of TuSMe shows significant improvement against other contemporary state-of-the-art approaches.
Ontology Based Verification of UML Class/OCL Model
Authors: Hafeez Abdul , Rehman Aqeel -ur-
Published: September 2018

Software models describe structures, relationships and features of the software. Modern software development methodologies such as MDE (Model Driven Engineering) use models as core elements. In MDE, the code is automatically generated from the model and model errors can implicitly shift into the code, which are difficult to find and fix. Model verification is a promising solution to this problem. However, coverage of all facets of model verification is a painful job and existing formal/semi-formal verification methods are greatly inspired by mathematics and difficult to understand by the software practitioners. This work considers particularly UML Class/OCL (Unified Modeling Language Class/Object Constraint Language) model and presents an ontology-based verification method. In the proposed method, a class diagram is transformed into ontology specified in OWL (Web Ontology Language) and constraints into SPARQL NAF (Negation as Failure) queries. This work tries to demonstrate that the proposed approach can efficiently cover all aspects of UML Class/OCL model verification.
The Effect of Information Opacity and Accounting Irregularities on Personal Lending Relationships: Evidence from Lender and Manager Co-Migration
Authors: Khan Urooj , Li Xinlei , Williams Christopher D. , Wittenberg-Moerman Regina
Published: September 2018

We examine how personal lending relationships between lenders and managers are affected by information and accounting environments of borrowing firms. We address this question by exploring whether, following managerial turnover, lenders migrate with the manager from the firm where a relationship developed (origin firm) to the manager's new firm (destination firm). We find that the opacity of the external information environment of the destination firm significantly increases the probability of lenders' co-migration, while accounting irregularities at both the destination and origin firms decrease it. We also show that co-migration is affected by a lender's monitoring efficiency. A lender's monitoring efficiency increases its co-migration probability when a manager moves to an opaque firm, but not when she moves to a transparent one. When the destination or origin firm experiences accounting irregularities, even lenders with strong monitoring capabilities are mostly reluctant to continue their relationship with a migrating manager.

Parafraseando a los viejos rockeros, Alonso Cano vuelve a Granada. Y lo hace con la fuerza incontestable e inmanente de sus obras más significativas, con el empuje y la garra de quien a través de la expresión de su arte, supo revolucionar el panorama artístico de su época, insuflándole ese necesario aire renovador y moderno conjugado con el apego referencial a los grandes maestros universales que le precedieron. Su inconmensurable figura artística, todavía mitificada por quienes no han sabido desquitarse de los lastres de impericias historiográficas, emerge sobremanera en la contemplación de cada una de las piezas expuestas en las salas de la remozada Curia Diocesana que, por otra parte, constituyen las más paradigmáticas del arte del otrora Racionero.

Bioinspired Catalytic Generation of Main-group Electrophiles by Cooperative Bond Activation
Authors: Forster Francis , Oestreich Martin
Published: September 2018

Catalytic processes involving cooperativity have seen tremendous progress in recent years and impressive new synthetic methodologies have been developed. Inspired by the cooperative heterolytic H2 splitting in [NiFe] hydrogenases, Ohki and Tatsumi designed cationic ruthenium
thiolate complexes with a tethered sulfur ligand. Over the last decade, we have demonstrated the facile activation of main-group hydrides such as hydrosilanes, hydroboranes, DIBAL–H, and hydrostannanes by the Ru–S bond in Ohki–Tatsumi complexes. This account illustrates these
E–H bond activations and highlights selected catalytic applications, particularly dehydrocouplings, of the generated main-group electrophiles.
Gold-catalyzed Dearomatization Reactions
Authors: An Juzeng , Bandini Marco
Published: September 2018

The advent of homogenous gold catalysis has revolutionized the way of approaching organic synthesis providing new and desirable solutions for challenging chemical manipulations of unactivated unsaturated hydrocarbons. In the realm of aromatic compounds, dearomatization protocols have
been emerging as valuable synthetic tools to densely functionalized polycyclic 3D-molecular scaffolds, starting from readily available 2D-aromatic congeners. Gold catalysis contributed substantially in expanding this scenario enabling the condensation of numerous electron-rich arenes with
hydrocarbons, resulting in the partial or total dearomatization of the aryl fragment. An overview of the most recent findings in the field, organized by type of electrophilic partners, is hereby presented.
A General Copper-based Photoredox Catalyst for Organic Synthesis: Scope, Application in Natural Product Synthesis and Mechanistic Insights
Authors: Deldaele Christopher , Michelet Bastien , Baguia Hajar , Kajouj Sofia , Romero Eugenie , Moucheron Cecile , Evano Gwilherm
Published: September 2018

Organic transformations can broadly be classified into four categories including cationic, anionic, pericyclic and radical reactions. While the last category has been known for decades to provide remarkably efficient synthetic pathways, it has long been hampered by the need for toxic
reagents, which considerably limited its impact on chemical synthesis. This situation has come to an end with the introduction of new concepts for the generation of radical species, photoredox catalysis – which simply relies on the use of a catalyst that can be activated upon visible
light irradiation – certainly being the most efficient one. The state-of-the-art catalysts mostly rely on the use of ruthenium and iridium complexes and organic dyes, which still considerably limits their broad implementation in chemical processes: alternative readily available catalysts
based on inexpensive, environmentally benign base metals are therefore strongly needed. Furthermore, expanding the toolbox of methods based on photoredox catalysis will facilitate the discovery of new light-mediated transformations. This article details the use of a simple copper complex which,
upon activation with blue light, can initiate a broad range of radical reactions.

Authors: Silva Fabiano Couto Corrêa da
Published: September 2018

O grande volume de dados disponíveis em portais governamentais atinge o status de dados realmente abertos quando ocorre uma comunicação social bidirecional entre a administração pública e a população. Um dos pontos chave para tornar essa comunicação efetiva é a disponibilização de dados por meio de ferramentas que possibilitem compreender seu significado e serem reutilizados. Este artigo discute aspectos relacionados com a apresentação visual de dados abertos disponíveis pelo governo e introduz uma técnica efetiva para visualização de informações por meio de um estudo de caso. Com o intuito de demonstrar o potencial da visualização de dados públicos, exploramos o uso de de uma ferramenta que possibilitou representar conjuntos de dados de acesso aberto. Foi desenvolvido uma representação gráfica de uma fonte de dados selecionada aleatoriamente para demonstrar como a visualização de dados pode ser útil para facilitar que os cidadãos entendam as interconexões e os relacionamentos causa-efeito que estão por trás de cada atividade ou conjunto de políticas públicas.

Authors: Gracioso Luciana De Souza
Published: September 2018

O objetivo deste estudo é investigar em que medida as pesquisas na Ciência da Informação (CI) tem aproximado às das técnicas de Deep Learning, sendo relacionadas à representação, descrição e recuperação de imagens na Web, e assim, aferir da mais valia destas pesquisas quando aplicadas aos métodos da área da CI. A partir de uma revisão integrativa de literatura nacional e internacional de modo contextualizado na CI, os documentos recuperados foram analisados conforme os critérios da revisão integrativa, identificando um conjunto de operações que poderiam ser integrados nas metodologias de representação e descrição de imagens desenvolvidas e consolidadas no campo da CI. Conclui-se que ainda há uma lacuna nas pesquisas em CI tanto no âmbito nacional como internacional sobre Deep Learning e que recursos desta nova estrutura de programação podem ser aproximados aos métodos já validados pela área.
Bibliotecas escolares no Brasil: uma análise dos dados estatísticos do Instituto Nacional de Estudos e Pesquisas Educacionais

Published: September 2018

A Lei nº 12.244/2010 determina que as escolas públicas e privadas de todos os sistemas de ensino contem com bibliotecas num prazo de dez anos. Para saber a quantidade de bibliotecas a serem criadas, considerou-se necessário analisar as estatísticas sobre bibliotecas coletadas pelo Instituto Nacional de Estudos e Pesquisas Educacionais Anísio Teixeira. O objetivo deste estudo foi compreender a consistência dos dados sobre bibliotecas escolares do Censo Escolar da Educação Básica. Especificamente, buscou-se identificar o conceito de biblioteca utilizado na coleta dos dados, como os dados são coletados e como têm sido apresentados. Para tanto, utilizaram-se os seguintes documentos: Formulários, Cadernos de Instruções, Resumos Técnicos e Notas Estatísticas, cobrindo o período 2009 a 2017. Os resultados revelaram que o Censo coletou dados separados sobre bibliotecas e salas de leitura, porém, na apresentação os dois espaços não foram diferenciados. A trajetória da biblioteca nos documentos do Censo indicou um percurso irregular que se estabilizou somente a partir de 2011. No Censo, a biblioteca é um “local”, o que pressupõe que a escola conte com um espaço específico para esse fim e conta com um “profissional especializado”, o bibliotecário. Conclui-se que as inconsistências e ambiguidades constatadas na coleta e apresentação dos dados do Censo impossibilitam estimar adequadamente a quantidade de bibliotecas a serem criadas em função da exigência da Lei nº 12.244.

Authors: Supo Julia , Suaiden Emir José
Published: September 2018

Esta pesquisa analisa o uso das Bibliotecas Digitais da Biblioteca Central (BCE) pelos estudantes indígenas da Universidade de Brasília (UnB), na realização das atividades acadêmicas e de pesquisa. O estudo tem como objetivos específicos identificar os perfis acadêmicos dos estudantes indígenas na UnB; detectar se esses estudantes conhecem as bibliotecas digitais da BCE/UnB e distinguir suas competências informacionais no uso destas plataformas; verificar como eles as utilizam em suas atividades acadêmicas e de pesquisa; e, por último, constatar possíveis dificuldades dos estudantes indígenas no uso das bibliotecas digitais. O estudo é de natureza teórica, exploratória e descritiva. Do ponto de vista metodológico, trata-se de uma abordagem quali-quantitativa, não experimental e de cunho etnográfico. A amostra abrangeu estudantes indígenas matriculados na UnB. Os resultados mostraram que esses estudantes acessam às bibliotecas digitais, porém, com frequência mínima. Em relação ao comportamento informacional, embora o estudo mostre que eles estão influenciados pela modernidade, quando buscam informações para satisfazer suas necessidades informacionais, as bibliotecas digitais da BCE não são prioridade, pois preferem acessar o buscador Google.

Authors: Manhique Ilídio Lobato Ernesto , Casarin Helen De Castro Silva
Published: September 2018

As análises de citação e cocitação são indicadores bibliométricos que fornecem dados objetivos para a compreensão da estrutura intelectual de um domínio do conhecimento. Esta pesquisa teve como objetivo caracterizar, a partir da análise de citações e cocitações, a estrutura intelectual dos estudos da competência informacional com enfoque na abordagem fenomenográfica ou relacional. Especificamente, mapeou-se os autores mais produtivos, autores mais citados, sua filiação institucional, países que mais produzem sobre a temática e criou-se, por meio do software Ucinet, a rede de cocitação indicando a frequência de cocitação entre os autores. A coleta de dados foi feita por meio de um levantamento na base de dados internacional – SCOPUS, - utilizando a seguinte expressão de busca ("information literacy") AND ("phenomenographic" OR "relational*"). A pesquisa retornou apenas 18 trabalhos válidos, todos na língua inglesa, maioritariamente, produzidos por autores da Austrália, de onde provém o trabalho seminal sobre a abordagem fenomenográfica da competência informacional. Isto mostra que esta perspectiva teórico-metodológica ainda está em busca de sua penetração no campo da Ciência da Informação. Conclui-se que é necessário que sejam feitos estudos futuros, englobando outras bases de dados internacionais para se ter o contexto global sobre a estrutura intelectual deste objeto.
