Authors: Acosta Juan Jose Bonnin , Cabrera María Gloria , Ibras Rubén Franco , González Jorge Daniel , Chamorro Sérgio Manuel , Escobar Jorge
Published: March 2018

A agricultura de precisão é uma importante ferramenta para maximizar a produção. Nela mapas de produtividade indicam a localização de áreas críticas, ajudando a fazer intervenções localizadas, a fim de aumentar a produtividade e consequentemente a rentabilidade. Objetivou-se avaliar a variabilidade espacial da produtividade, perdas quantitativas na colheita mecanizada e a lucratividade em área de produção de soja. Realizou-se um levantamento de dados georreferenciados em uma área de 20,90 ha. Foram utilizadas técnicas geoestatísticas para a determinação da variabilidade espacial. A dependência espacial foi moderada para todos os parâmetros estudados, observando-se regiões com maior ou menor variabilidade espacial na produtividade, nas perdas quantitativas de grãos e na lucratividade. A produtividade média foi de 3.748,63 kg.ha-1 e 67,65 % da área total apresentou patamares de produtividade de 3.254,05 a 3.609,91 kg.ha-1 e de 3.609,91 a 3.965,91 kg.ha-1. As perdas totais de grãos encontrados por ocasião da colheita foram baixas (49,59 kg.ha-1). A lucratividade média foi 1.252,54 $.ha-1, com duas regiões representativas de lucro de 1.187,20 a 1.354,78 $.ha-1 e de 1.019,62 a 1.187,20 $.ha-1, correspondente a 67,65 % da área total. Pode-se dizer que a semelhança na variabilidade espacial dos mapas de produtividade e lucratividade ocorre por este último ter sido confeccionado a partir de dados de produtividade, o que permitiria ao produtor investigar os motivos das baixas produtividades, sugerindo eventualmente um estudo da fertilidade do solo, no intuito de encontrar e corrigir o problema que levou às baixas produtividades, a fim de melhorar a relação custo/benefício, tendo como resultado um maior lucro.

Published: March 2018

O molibdênio (Mo) está associado aos processos de metabolismo do nitrogênio (N) devido a sua participação na formação e na atividade da redutase do nitrato. A deficiência de Mo pode acarretar também deficiência de N, comprometendo o rendimento das culturas. Objetivou-se avaliar o efeito de doses de Mo na produtividade do milho e na concentração de nutrientes nas folhas. Foi utilizado o delineamento experimental em blocos casualizados com quatro repetições. Os tratamentos foram constituídos de seis doses de Mo: 0, 25, 105, 210, 315 e 420 g ha-1. Como fonte de Mo, empregou-se o molibdato de sódio, suspensão concentrada, com 25 % de Mo. Avaliaram-se os teores de nutrientes nas folhas, na época do florescimento, e a produtividade de grãos do milho. Os dados foram submetidos a análises de variância 5 % de significância. Os atributos avaliados não se modificaram com as doses de Mo. A ausência de resposta à aplicação de Mo foliar pode ser devido às quantidades adequadas do  nutriente no solo como também nas sementes.

Authors: Moura Aloysio Souza de , Machado Felipe Santana , Corrêa Bruno Senna , Fontes Marco Aurélio Leite
Published: March 2018

Recent compiled papers demonstrate several gaps in occurrence records and distribution limits mainly due to information deficiency, hindering the management and planning of preservation and conservation efforts. Therefore, the objective of this study is to present and analyze new records of four Neotropical Primates species: Callicebus moloch, Mico emiliae, Ateles marginatus and Cebus (Sapajus) libidinosus. Data collection was assessed by interviews, census on pre-existing trails and direct observations. The expeditions took place in the cities of Pains (Minas Gerais state), Serra do Salitre (Minas Gerais state) and Guarantã do Norte (Mato Grosso state). Mico emilie, C. moloch and A. marginatus were recorded in Guarantã do Norte and C. libidinosus was recorded in Serra do Salitre and Pains. A small expansion of occurrence area to C. libidinosus was observed. We recommend new mammal inventories in order to understand the faunal diversity in these areas and propose new conservation actions.

For centuries character of Medea has maintained its significance and comprised source of inspiration for the representatives of various spheres of fine arts.[1] Of course, regarding the contexts of the epochs (conceptual and esthetic position) and author’s intent, some motifs of the Argonauts’ myth and character of the woman of Colchis have been changing.

In this respect, novel „Megi, Georgian Girl“ by Georgian modernist writer, Grigol Robakidze is of interest. Text, first published in 1932 in Germany[2] was translated into Georgian in 2012 and it is not properly studied till now.
Taking European defence seriously: The naval operations of the European Union as a model for a Security and Defence Union
Authors: Espaliú Berdud Carlos
Published: March 2018

The two naval operations set up until now by the EU, Atalanta and Sophia, have demonstrated a growing level of consensus and willingness by Member States, a great number of which participating in both operations. Furthermore, and more clearly in the case of Atalanta but also in the first stages of Sophia, it can be said that these CSDP activities have been highly successful, taken into consideration the level of accomplishment of their respective goals. Having shown its potential, the launching of naval operations in crisis management could be seen as a step forward in the creation of a Security and Defence Union. Therefore, the next step in European integration regarding security matters can be the implementation of the Permanent Structured Cooperation anticipated in Article 42.2 and 46 of TEU and developed in Protocol No 10 annexed to the Lisbon Treaty. That achievement would be the landmark that would generate the nucleus from which a Security and Defence Union can emergeReceived: 14 December 2017Accepted: 10 January 2018Published online: 28 March 2018

La dimensión social de la política de cohesión
Authors: Bilbao Ubillos Javier
Published: March 2018

El artículo valora la contribución de la política de cohesión a la dimensión social de la UE, partiendo de la evolución de su sentido, tanto desde el punto de vista conceptual como por el contexto cambiante de referencia, a medida que se incrementaba la heterogeneidad estructural de la Unión con las sucesivas ampliaciones. Tras repasar el tratamiento dispensado a la cohesión en la legislación primaria y en los presupuestos comunitarios, se recogen los indicios disponibles del impacto de los sucesivos programas y estrategias comunitarias en materia de cohesión, tratando de estimar los alcances más relevantes en términos de la dimensión social de la UE. Las conclusiones apuntan a que, pese a algunos logros tangibles que mejoran las condiciones de vida y de trabajo de los ciudadanos europeos, el enfoque de la política de cohesión se centra en los territorios, buscando tanto una reducción de las disparidades regionales como la legitimación de la Unión en los territorios más rezagados; en todo caso, es una política muy condicionada por las limitaciones de recursos y los requerimientos de calidad institucional y elegibilidad en las zonas receptoras.Recibido:27 noviembre 2017Aceptado: 09 enero 2018Publicación en línea: 28 marzo 2018
Automated processing of NGS data from raw sequencing files to ready-to-use information tables for genome modeling
Authors: Deelen Robert , Wieland Martin , Gerber Susanne , Fournier David
Published: March 2018

Epigenetic features such as histone and DNA modifications are important mechanisms for the regulation of gene expression and for cell and tissue development. As a result, extensive efforts are currently undertaken using next-generation sequencing (NGS) to generate vast amounts of data regarding the epigenetic regulation of genomes. Several tools and frameworks for the processing of these NGS data have been developed in the last decade. Nevertheless, each user still bares the challenge to integrate all these tasks to perform the analysis. This procedure is not only tedious but also resource-intensive due to the putative large processing power involved. To automate, standardize and speed up the handling of NGS data, with focus on ChIP-seq data, we present a user-friendly pipeline that automatically processes a list of sequencing data files and returns a ready-to-use purified table for subsequent modelling or analysis attempts.

Authors: Daniel Lindomar Pegorini
Published: March 2018

Sendo a educação apontada como eficiente mecanismo de transferência e redistribuição de renda, o presente artigo analisou como o background familiar e o mercado de trabalho impactam sobre a decisão de progressão entre níveis escolares no Brasil. O procedimento consiste em um stepwise para verificar se a ausência de certos fatores causa viés de omissão. Os resultados revelaram que a exclusão de características do background familiar causa viés de omissão de variável relevante, indicando que as mesmas são importantes na tomada de decisão quanto ao nível educacional. Fatores ligados ao mercado de trabalho e geográficos também se mostraram importantes, principalmente o fato de residir na zona rural, que impõe custos de transação adicionais para obter níveis mais elevados de educação. Constatou-se que vários fatores estavam ligados direta ou indiretamente com a renda, evidenciando que esse seria um canal condicionante para o aumento da escolaridade (capital humano). Políticas públicas que foquem a mitigação da pobreza podem exercer efeitos positivos sobre a quantidade de educação no país. Por fim, chegou-se à conclusão de que mesmo significativos, as características consideradas exercem pouca influência sobre a decisão de completar níveis elevados de educação, que estaria mais ligada à habilidade inata do indivíduo.

Authors: Amattouch M. R. , Belhadj H. , Nagid N.
Published: March 2018

The purpose of this work is the study of a new approach of domain decomposition method, the optimized order 4 method(OO4), to solve a reaction advection diusion equation. This method is a Schwarz waveform relaxation approach extending the known OO2 idea. The OO4 method is a reformulation of the Schwarz algorithm with specific conditions at the interface. This condition are a dierential equation of order 1 in the normal direction and of order 4 in the tangential direction to the interface resulting of artificial boundary conditions. The obtained scheme is solved by a Krylov type algorithm. The main result in this paper is that the proposed OO4 algorithm is more robust and faster than the classical OO2 method. To confirm the performance of our method , we give several numerical test-cases.
Accurate Multistep Multi-derivative Collocation Methods Applied to Chaotic Systems
Authors: Yakubu Gulibur Dauda
Published: March 2018

Accurate multistep multi-derivative collocation methods are derived for the numerical integration of chaotic systems. These methods have high order of accuracy, with A-stable regions of absolute stability. Although the calculation of the third derivative terms in the methods is relatively high compared to the rst and second derivative terms, the advantage gained makes them suitable for solving chaotic system of equations with large eigenvalues. The stability characteristic properties and order of accuracy of the methods are studied. Figurative comparisons of the solution curves obtained are in good agreement with the exact solutions which demonstrate practically the eectiveness of the proposed methods.

Protein-Protein Interaction Network Analysis and Identification of Key Players in nor-NOHA and NOHA Mediated Pathways for Treatment of Cancer through Arginase Inhibition: Insights from Systems Biology
Authors: Ahammad Ishtiaque
Published: March 2018

L-arginine is involved in a number of biological processes in our bodies. Metabolism of L-arginine by the enzyme arginase has been found to be associated with cancer cell proliferation. Arginase inhibition has been proposed as a potential therapeutic means to inhibit this process. N-hydroxy-nor-L-Arg (nor-NOHA) and N (omega)-hydroxy-L-arginine (NOHA) has shown promise in inhibiting cancer progression through arginase inhibition. In this study, nor-NOHA and NOHA-associated genes and proteins were analyzed with several Bioinformatics and Systems Biology tools to identify the associated pathways and the key players involved so that a more comprehensive view of the molecular mechanisms including the regulatory mechanisms can be achieved and more potential targets for treatment of cancer can be discovered. Based on the analyses carried out, 3 significant modules have been identified from the PPI network. Five pathways/processes have been found to be significantly associated with nor-NOHA and NOHA associated genes. Out of the 1996 proteins in the PPI network, 4 have been identified as hub proteins-SOD, SOD1, AMD1, and NOS2. These 4 proteins have been implicated in cancer by other studies. Thus, this study provided further validation into the claim of these 4 proteins being potential targets for cancer treatment.

Node localization is one of the key technologies of wireless sensor networks (WSN). Due to the indoor environment requires a high positioning accuracy, an improved algorithm based on RSSI is put forward. In terms of RSSI ranging, the error correction coefficient received from self-correcting locator beacon nodes, and then had been applied to distance solving from unknown nodes to the beacon nodes. In the choice of weights, the algorithm uses inverse distance and replaces the method of determining the distance and the reciprocal of the weights, and also fixes the weight factor. On the complexity of the algorithm, select one of the most recent four from unknown node to beacon nodes, reducing the amount of data calculation. Simulation results show that the proposed algorithm positioning accuracy has been greatly improved.

abstract

Fermentation is extremely a crucial process which is primarily responsible for tea quality. It is an oxidation process where tea leaves change colour and smell. Relative humidity (RH) and temperature are two important physical parameters which play a crucial role in producing good quality tea. This work is an attempt to develop and implement a monitoring system for fermentation room of tea factory. Due to the larger dimension of the fermentation room, it requires several numbers of monitoring point for estimating average condition. Sensor node at each monitoring point is connected via RS 485 network which works with a protocol developed for this purpose. Each sensor node consists of sensors, signal conditioning, controller and RS485 transceiver. All these nodes are calibrated and the voltage level of RS 485 system is converted to RS 232 voltage level to make compatible with the COM port of the PC. Data acquisition software is developed with the help of NI Lab VIEW.

Connectivity offers the foundation for achieving required quality of service in all WSN applications. By the concept of cyclic-like topologies proposed and their property proved, we find a new searching method based on cyclic paths on nodes and their combination, which cuts down the cost of ensuring bi-connectivity in this problem. On the basis of graph and probability theory, our centralized connectivity-aware algorithm with cyclic-like topologies and computation of link reachability is proposed. Results of the experiments show that, our topology control algorithm could be more satisfactory than that of another two algorithms in different scales of networks.

A Framework For “Energy-Saving Strategies”: Utilization of A cue Offering Interface
Authors: Kishi Yasutaka , Ito Kyoko , Nishida Shogo
Published: March 2018

Mass consumption of energy is a big problem. Energy-saving activities which are a solution to this problem have been attracting a lot of attention. Nevertheless, in order to engage in thorough energy-saving activities, consumers need support; on the other hand, even with support, the effects seem to be only temporary. In this paper, to obtain a long-term effect, we focus on developing a method to raise consumers’ awareness about energy-saving behavior. To this end, we designed an interface which offers consumers the cue to think about energy-saving activities and conducted a 2week-experiment using the interface with 10 participants. The results suggest two things. First, offering cues increases the number of the energy-saving activities. Second, the more times they perform an activity, the less likely it is that they will change their way of thinking about the activity as time passes. We discuss a more effective method of helping consumers create energy-saving strategies.

Authors: Lu Yan Hong , Zhang Ming
Published: March 2018

In wireless sensor networks (WSNs), node’s locations play a critical role in many applications. Having a GPS receiver on every sensor node is costly. In this paper, we propose an adaptive mobile anchor localization algorithm based on ant colony optimization, firstly, some virtual anchor nodes are distributed in the area, second, ant colony was used which has the maximum of transition probabilities to obtain the optimal path, last, the centroid-weighted localization algorithm was proposed to locate the position of unknown nodes. Simulation results show that the localization accuracy of the proposed algorithm is better than the traditional centroid algorithm, the more number of anchor nodes, namely, the density is bigger, the position errors is smaller. Under the same anchor nodes, the more number of unknown nodes, the position errors is smaller and the overall trend is downward.
Eigenvector Centrality: Illustrations Supporting the Utility of Extracting More Than One Eigenvector to Obtain Additional Insights into Networks and Interdependent Structures
Authors: Iacobucci Dawn , McBride Rebecca , Popovich Deidre L.
Published: March 2018

Among the many centrality indices used to detect structures of actors’ positions in networks is the use of the first eigenvector of an adjacency matrix that captures the connections among the actors. This research considers the seeming pervasive current practice of using only the first eigenvector. It is shows that, as in other statistical applications of eigenvectors, subsequent vectors can also contain illuminating information. Several small examples, and Freeman’s EIES network, are used to illustrate that while the first eigenvector is certainly informative, the second (and subsequent) eigenvector(s) can also be equally tractable and informative.

Prediction systems, such as the coastal ecosystem models, often incorporate complex non-linear ecological processes. There is an increasing interest in the use of probabilistic forecasts instead of deterministic forecasts in cases where the inherent uncertainties in the prediction system are important. The primary goal of this study is to set up an operational ensemble forecasting system for the prediction of the Chlorophyll-a concentration in coastal waters, using the Generic Ecological Model. The input ensemble is generated from perturbed model process parameters and external forcings through Latin Hypercube Sampling with Dependence. The forecast performance of the ensemble prediction is assessed using several forecast verification metrics that can describe the forecast accuracy, reliability and discrimination. The verification is performed against in-situ measurements and remote sensing data. The ensemble forecast moderately outperforms the deterministic prediction at the coastal in-situ measurement stations. The proposed ensemble forecasting system is therefore a promising tool to provide enhanced water quality prediction for coastal ecosystems which, with further inclusion of other uncertainty sources, could be used for operational forecasting.

The streams in a watershed form a hierarchical network system. From the perspective of the river continuum, this classification system is the result of gradual increase in traffic. This study analyzed the riparian species richness, diversity and environmental factors along a six-order hierarchical mountain river in the Donghe watershed, China. A total of 34 sampling sites were sampled to study the spatial distribution of riparian plants among different stream orders. The results showed: Environmental factors among stream orders had significant differences. Among stream order, species richness showed remarkable differences. The species richness rose firstly and dropped afterwards except for tree species richness; tree species richness decreased while stream order increased. The same is true for shrub quadrat species richness. Shannon-Wiener diversity, Simpson dominance and Pielou uniformity showed significant difference among stream orders; Shannon-Wiener diversity rose firstly then dropped afterwards. For integrated environmental factors and community characteristics, we found the changes of stream orders had a significant impact on riparian habitats and riparian vegetation. Further analysis showed that riparian vegetation experienced different types and degrees of disturbance in different stream orders. This meant that a hierarchical management strategy should be applied to riparian vegetation management.
HUMANISTIC INFORMATION STUDIES: A PROPOSAL
Authors: Kunneman Harry
Published: March 2018

In this two-part paper I want to introduce a conceptual framework for Humanistic Information Studies. This framework is provisional. As it stands, its main use is to show a path for the further development of Information Studies in a critical and humanistic direction. In the first part of this two-part paper, I will focus on the epistemological questions connected with the conceptual foundations of Humanistic Information Studies (or HIS): what are the characteristics of the specific form of knowledge sought after in HIS. In the second part I will further elaborate the proposal developed in the first part from the standpoint of the specific, form of normative professionalism and of organizational transformation sought after and furthered by Humanistic Information Studies. ESTUDOS HUMANISTICOS DA INFORMAÇÃO: UMA PROPOSTAResumoNeste artigo, composto por duas partes,  pretende-se introduzir uma quadro conceitual para os Estudos Humanísticos da Informação. Esta quadro é provisório. Do modo como está apresentado sua função principal é indicar um caminho para o desenvolvimento dos Estudos da Informação em um sentido crítico e humanista. A primeira parte do artigo concentram-se em questões epistemológicas relacionadas com fundamentos conceituais dos Estudos Humanísticos da Informação (EHI): quais são as características da específica forma de conhecimento buscadas para os EHI.  Na segunda parte trata-se do desenvolvimento da proposta apresentada na primeira, partindo de um ponto de vista específico, a saber, uma forma de profissionalismo normativo e de transformação organizacional, buscados e promovidos pelos Estudos Humanísticos da Informação.
O SENSO COMUM DE INFORMAÇÃO: QUESTÕES OPORTUNAS
Authors: Gonzalez Marcos
Published: March 2018

Problematizamos o conceito de informação, sob a perspectiva da Linguística Sociocognitiva, em especial da teoria da metáfora conceptual e da teoria dos frames semânticos, a fim de verificar se a terminologia predominante da Ciência da Informação (CI) é próxima do “senso comum”, como querem alguns autores da área. De fato, pudemos descrever o esquema cognitivo em que o conceito de informação é produtivo. Identificamos um componente da metáfora do canal, a metáfora INFORMAÇÃO É CONTEÚDO, capaz de confirmar a suspeita dos epistemólogos da CI e ir além: ela revela uma maneira mecânica de “falar sobre comunicação” que é de um “senso comum” desde há muitos séculos. Qual “senso comum”? Argumentando que a metáfora INFORMAÇÃO É CONTEÚDO faz mais sentido no contexto da comunicação escrita do que na falada, sugerimos uma revisão crítica dos efeitos que o letramento em massa aos seis anos poderia estar provocando na mentalidade ocidental: ao valorizar a escrita, tecnologia fundamental para a sustentabilidade das “sociedades da informação”, estaremos negligenciando a oralidade e, em consequência, negando nossa humanidade? THE COMMONSENSE OF INFORMATION: TEMPESTIVE QUESTIONSAbstractWe problematize the concept of information, from the perspective of socio-cognitive linguistics, especially that from the conceptual metaphor and semantic frames theories, in order to check whether the prevailing terminology of the Information Science (IS) is close to the “commonsense”, as some authors whish. In fact, we describe a cognitive scheme in which the concept of information is productive. A component of the conduit metaphor, INFORMATION IS CONTENT, seems to confirm the suspicion of IS epistemologists and more: it reveals a mechanical way to “speek about communication” that is a “commonsense” for centuries. Which “commonsense”? Arguing that the metaphor INFORMATION IS CONTENT makes more sense in the context of written language than in spoken one, we suggest a critical review of the effects that mass literacy at age six could be causing in Western mind: giving prestige to the writing language, a key technology for the sustainability of “information societies”, are we neglecting orality and therefore denying our humanity?
TRABALHO, INFORMAÇÃO E CONHECIMENTO: RELENDO MARX NA ERA DA INFORMAÇÃO
Authors: Marques Rodrigo Moreno
Published: March 2018

Dentre os problemas que têm norteado nossas investigações, duas indagações ganham destaque. Como a informação e o conhecimento estão inseridos no arcabouço teórico de Karl Marx? Que janelas o pensamento de Marx nos abre para discutir do papel da informação e do conhecimento no universo do trabalho, na atualidade? Fazendo dessa perspectiva objeto de pesquisa, busca-se apreender a inserção da informação e do conhecimento no arcabouço teórico marxiano, tendo como referências principais O Capital, Teorias da mais-valia e Capítulo VI Inédito. A exposição aborda alguns construtos categoriais da obra marxiana onde a informação e o conhecimento laboral são elementos centrais, a exemplo das categorias mercadoria, força de trabalho, trabalho simples e trabalho complexo, subsunção formal e subsunção real, trabalhador coletivo, trabalho produtivo e trabalhador produtivo. Após a discussão das ideias de Marx, são apresentados alguns aspectos do trabalho na atualidade, para os quais o complexo categorial marxiano revela-se pertinente e necessário. Labour, information and knowledge: rereading marx in the information age AbstractAmong the problems that have guided our investigations, two questions are crucial. How information and knowledge take part in the theoretical framework conceived by Karl Marx? Which windows does Marx's thought open to discuss the role of information and knowledge in the current labour realm? Adopting this perspective, we aim to apprehend the insertion of information and knowledge in the Marxian theoretical framework, especially in the books Capital, Theories of Surplus-Value and Chapter VI (unpublished). The exposition presents some Marxian categorical constructs where information and labour knowledge are central elements, such as the categories commodity, labour force, simple unskilled labour and complex skilled labour, formal subsumption and real subsumption, collective labour, productive labour and productive worker. After discussing the ideas of Marx, we present some aspects of the contemporary labour, where the Marxian categorical complex is pertinent and necessary.
