Alienness: Rapid Detection of Candidate Horizontal Gene Transfers across the Tree of Life
Authors: Rancurel Corinne , Legrand Ludovic , Danchin Etienne GJ
Published: September 2017

Horizontal gene transfer (HGT) is the transmission of genes between organisms by other means than parental to offspring inheritance. While it is prevalent in prokaryotes, HGT is less frequent in eukaryotes and particularly in metazoan. Here, we propose Alienness, a taxonomy-aware web application that parses BLAST results against public libraries to rapidly identify candidate HGT in any genome of interest. Alienness takes as input the result of a BLAST of a whole proteome of interest against any NCBI protein library. The user defines recipient (e.g. metazoan) and donor (e.g. bacteria, fungi) branches of interest in the NCBI taxonomy. Based on the best BLAST E-values of candidate donor and recipient taxa, Alienness calculates an Alien Index (AI) for each query protein. An AI >0 indicates a better hit to candidate donor than recipient taxa and a possible HGT. Higher AI represent higher gap of E-values between candidate donor and recipient and a more likely HGT. We confirmed the accuracy of Alienness on phylogenetically confirmed HGT of non-metazoan origin in plant-parasitic nematodes. Alienness scans whole proteomes to rapidly identify possible HGT in any species of interest and thus fosters exploration of HGT more easily and largely across the tree of life.
Full-Stokes, Multi-Frequency Radio Polarimetry of Fermi Blazars; Monitoring and Modelling
Authors: Angelakis Emmanouil , Myserlis Ioannis , Zensus Anton J
Published: September 2017

The polarised emission from AGN jets carries information about the physical conditions at the emitting plasma elements while its temporal evolution probes the physical processes that introduce variability and dynamically modify the local conditions. Here we present the analysis of multi-frequency radio linear and circular polarisation datasets with the aim to exactly quantify the conditions in blazar jets. Our analysis includes both the careful treatment of observational datasets and numerical modelling for the reproduction of synthetic polarisation curves that can be compared to the observed ones. In our approach the variability is attributed to traveling shocks. The emission from the cells of our jet model is computed with radiative transfer of all Stokes parameters. The model also accounts for Faraday effects which map the low-energy particle populations. We present two extreme cases in terms of the significance of Faraday conversion in the production of circular polarisation. As we show, in both regimes the model gives realistic reproduction of the observed emission.
On Near Optimality of One-sample Update for Joint Detection and Estimation
Authors: Cao Yang , Xie Liyan , Xie Yao , Xu Huan
Published: September 2017

Sequential hypothesis test and change-point detection when the distribution parameters are unknown is a fundamental problem in statistics and machine learning. We show that for such problems, detection procedures based on sequential likelihood ratios with simple one-sample update estimates such as online mirror descent are nearly second-order optimal. This means that the upper bound for the algorithm performance meets the lower bound asymptotically up to a log-log factor in the false-alarm rate when it tends to zero. This is a blessing, since although the generalized likelihood ratio (GLR) statistics are optimal theoretically, but they cannot be computed recursively, and their exact computation usually requires infinite memory of historical data. We prove the nearly second-order optimality by making a connection between sequential analysis and online convex optimization and leveraging the logarithmic regret bound property of online mirror descent algorithm. Numerical and real data examples validate our theory.
Transparent Pullulan/Mica Nanocomposite Coatings with Outstanding Oxygen Barrier Properties
Authors: Uysal Unalan Ilke , Boyaci Derya , Trabattoni Silvia , Tavazzi Silvia , Farris Stefano
Published: September 2017

This study presents a new bionanocomposite coating on poly(ethylene terephthalate) (PET) made of pullulan and synthetic mica. Mica nanolayers have a very high aspect ratio (α) at levels much greater than that of conventional exfoliated clay layers (e.g., montmorillonite). A very small amount of mica (0.02 wt%, which is ϕ ≈ 0.00008) in pullulan coatings dramatically improved the oxygen barrier performance of the nanocomposite films under dry conditions, whereas this performance was partly lost as the environmental relative humidity (RH) increased. This outcome was explained in terms of the perturbation of the spatial ordering of mica sheets within the main pullulan phase because of RH fluctuations, as confirmed by modelling of the experimental OTR data according to Cussler’s model. The presence of the synthetic nanobuilding block (NBB) led to a decrease in both static and kinetic coefficients of friction compared with neat PET (≈12% and 23%, respectively) and PET coated with unloaded pullulan (≈ 26% reduction in both coefficients). In spite of the presence of the filler, all of the coating formulations did not significantly impair the overall optical properties of the final material, which exhibited haze values below 3% and transmittance above 85%, with the only exception represented by the formulation with the highest loading of mica (1.5 wt%, which is ϕ ≈ 0.01). These findings revealed, for the first time, the potential of the NBB mica to produce nanocomposite coatings in combination with biopolymers for the generation of new functional features, such as transparent high oxygen barrier materials.

Published: September 2017

Autonomous and cooperative vehicle systems represent a key priority in the automotive realm. In order to support the development, networked driving simulation can be utilized as a safe, cost-effective experimental replica of real traffic environments. In networked driving simulation, a group of independent systems collaborate to achieve a common task: multi-driver traffic scenario simulation. Different system complexity levels are necessary to fulfill the requirements of various application scenarios, such as development of vehicle systems, analysis of driving behavior, and training of drivers. With myriad alternatives of available systems and components, developers of networked driving simulation are typically confronted with high design complexity. There is no systematic approach to date for the design of networked driving simulation according to the application requirements. This paper presents a novel design method for networked driving simulation. The method consists mainly of a procedure model accompanied by a configuration software. The procedure model includes the necessary phases for the systematic design of application-oriented platforms of networked driving simulation. The configuration software embeds supportive decision-making processes that enable developers to create different system models. The design method was validated by generating system models and developing platforms of networked driving simulation for three different application scenarios.

Glycerol is a subproduct of biodiesel production and represents an important problem when generated in large scale. Alternatives that can utilize this unrefined byproduct is of potential interest. It is herein described the synthesis of a series of 1,2,3-triazoles using glycerol as starting material. The key step involved in the preparation of triazolic derivatives corresponded to the Copper(I)-catalyzed Azide-Alkyne Cycloaddition (CuAAC), also known as click reaction, between 4-(azidomethyl)-2,2-dimethyl-1,3-dioxolane (3) and different terminal alkynes. The eight prepared derivatives were evaluated with regard to their fungicide, phytotoxic and cytotoxic activities. The fungicide activity was assessed in vitro against Colletotrichum gloeosporioides, the causing agent of papaya anthracnose. It was found that the compounds 1-(1-((2,2-dimethyl-1,3-dioxolan-4-yl)methyl)-1H-1,2,3-triazol-4-yl)cyclohexanol (4g) and 2-(1-((2,2-dimethyl-1,3-dioxolan-4-yl)methyl)-1H-1,2,3-triazol-4-yl)propan-2-ol (4h) demonstrated high efficiency on controlling C. gloeosporioides when compared to the commercial fungicide tebuconazole. The triazoles did not present any phytotoxic effect when evaluated against Lactuca sativa. However, five derivatives were mitodepressive, inducing cell death detected by the presence of condensed nuclei and acted as aneugenic agents in the cell cycle of L. sativa. It is believed that glycerol derivatives bearing 1,2,3-triazole functionalities may represent a scaffold to be explored toward the development of new agents to control C. gloeosporioides.
Portfolio Selection with Random Liability and Affine Interest Rate in the Mean-Variance Framework
Authors: Chang Hao , Wang Chunfeng , Fang Zhenming
Published: September 2017

This paper studies a dynamic mean-variance portfolio selection problem with random liability in the affine interest rate environment, where the financial market consists of three assets: one risk-free asset, one risky asset and one zero-coupon bond. Assume that short rate is driven by affine interest rate model and liability process is described by the drifted Brownian motion, in addition, stock price dynamics is affected by interest rate dynamics. The investors expect to look for an optimal strategy to minimize the variance of the terminal surplus for a given expected terminal surplus. The efficient strategy and the efficient frontier are explicitly obtained by applying dynamic programming principle and Lagrange duality theorem. A numerical example is given to illustrate our results and some economic implications are analyzed.
A Reversed Geo–Dynamic Approach for Brownfield Rejuvenation
Authors: Ibrahim Mahmoud (Mudi) , Hollmann Gregor
Published: September 2017

Brownfields in this paper are defined as mature fields where production declined to less than 35–40% of the plateau rate and where primary and secondary reserves have been largely depleted. Big data, high field complexity after a long production history, and slim economic margins are typical brownfield challenges.

In the exploration-and-production (E&P) industry, “sequential” field-evaluation approaches (first “static,” then “dynamic”), have proved successful for greenfield development, but often do not achieve satisfying results for brownfields. This paper presents a new work flow for brownfield re-evaluation and rejuvenation. The “reversed” geo-dynamic field modeling (GDFM) rearranges existing elements of reservoir evaluation to obtain a purpose-driven, deterministic reservoir model, which can be quickly translated into development scenarios.

The GDFM work flow is novel because (1) it turns upside down the discipline-driven sequential work flow (i.e., starts with the history match) and (2) it uses dynamic data as input to calibrate seismic (re-) interpretation that acts as a main integration step. It combines all available data already during horizon and fault mapping. Field diagnosis, flow-unit identification, well-test reanalysis, and petrophysical and geological interpretations are all combined in a cross-discipline interaction to guarantee data consistency. This directly ensures a fully integrated, “geo-dynamic” model that forms the basis for reservoir modeling. The full dynamic/static data coupling at an early stage is the main strength of the GDFM. It reduces the model complexity, and narrows the uncertainties. Project-execution time is considerably shortened by avoidance of the characteristic full-cycle loop iterations of the sequential approaches.

A brownfield example illustrates the benefits of GDFM: a consistent history match with high model accuracy and confidence. In the field example, the GDFM work flow has facilitated a turnover at only 70% of the original time budget. The ongoing drilling has confirmed model validity (“attic oil” predictions), thus further postponing the economic limit of the brownfield.

Authors: Pellizzer Eduardo Piza
Published: September 2017

As revisões sistemáticas surgiram no final da década de 1950, porém, somente no final da década de 1980 se consolidou na área da saúde.Frequentemente nos deparamos com estudos contraditórios, com amostragem e metodologia diferentes, estudos de laboratórios, simulações e relato de casos, entre outros. Estes possuem rigor e qualidades diferentes, tornando-se difícil a interpretação isolada, com o objetivo de aplicabilidade clinica. Muitas vezes estes estudos podem ser tendenciosos, e refletem a opinião de um especialista ou um grupo de pesquisadores; que levando em consideração a pirâmide de evidencia científica (visto que são a base da pirâmide), não deve ser levado em consideração.Portanto nos dias atuais, principalmente na área da saúde, o ensino nas universidades e as condutas clinicas adotadas pelos profissionais necessitam ser apoiadas em evidencias cientificas. Nesse sentido, destacamos a importância das revisões que se baseiam em métodos científicos rigorosos, conduzidas geralmente com estudos clínicos randomizados e que chegam a uma conclusão mais efetiva sobre o tema abordado.  E quando a maioria desses estudos apresentam dados homogêneos, podemos aplicar uma analise estatística e transforma-la em uma metanálise.Com o objetivo de conscientizar e divulgar a importância desses estudos, criamos um Encontro Anual do Grupo de Revisão Sistemática e/ou Metanálise do Programa de Pós-Graduação em Odontologia da Faculdade de Odontologia de Araçatuba, que ocorrera todos os anos no mês de dezembro, aberto a toda a comunidade odontológica.    Prof.Titular Eduardo Piza PellizzerCoordenador do 1º Encontro de Revisão Sistemática e/ou Meta-Análise do Programa de Pós-Graduação em Odontologia FOA/UNESP

Published: September 2017

La dosis letal (DL50) y reducción media del crecimiento (RC50) son parámetros utilizados para seleccionar dosis de irradiación adecuadas e inducir mutaciones para realizar mejoramiento genético vegetal. El objetivo fue determinar la DL50 yRC50 para conocer la dosis ótima de irradiación con Co60 en semilla de pasto llorón, buffel, banderita y navajita. Se evaluaron seis dosis de irradiación con Co60 en semilla: 100, 200, 300, 450, 600 y 900 Gray (Gy) y un tratamiento control (T-0; sin irradiación). Las variables evaluadas fueron porcentaje de germinación (%GE), índice de velocidad de germinación (IVG), longitud de plúmula (LP) y longitud de radícula (LR). Se realizó análisis de regresión y comparación de medias con la prueba de Dunnett. Mediante la ecuación de regresión se estimó la DL50 para el %GE, así como RC50 para el resto de las variables. La DL50 se ponderó con 55%, mientras que la RC50 se ponderó en 15% para cada una de las tres variables restantes. En general, los valores de  las variables disminuyeron (P<0.05) conforme se incrementó la dosis de irradiación, lo cual permitió determinar la DL50 y RC50 para cada especie. La media ponderada se obtuvo a los 628 Gy, 712 Gy, 698 Gy y 411 Gy para pasto llorón, buffel, banderita y navajita, respectivamente. Se recomiendan las dosis planteadas en este estudio, ya que esto permitirá plantear las bases para realizar mejoramiento genético a través de mutagénesis con irradiación gamma en los pastos evaluados.
Assessing the complex adaptability of regional water security systems based on a unified co-evolutionary model
Authors: Yao Jiping , Ren Yongtai , Wei Shuai , Pei Wei
Published: September 2017

A unified co-evolutionary model was developed to study the adaptability conditions of regional water security systems, which is important for the coordinated development of these systems. In this work, the main factors that affect the adaptability of regional water security systems, the contribution of each sub-problem domain to the development of the problem domain, and the fitness values of regional water security systems were analyzed based on the model. Taking Jiansanjiang as an example, the results showed that in 2002–2011, the water resources system had strong adaptability and contributed greatly to improve the adaptability of the water security system; the socioeconomic system had poor adaptability to environmental changes and contributed little to the adaptability of the water security system; and the eco-environmental system was barely able to adapt to the changing environment and contributed less to the adaptability of the water security system. Due to the influence of the socioeconomic and eco-environmental systems, the adaptability of the water security system was relatively weak. Therefore, strengthening the sustainable utilization of water resources, promoting the coordinated development of the social economy, and improving the quality of the ecological environment are effective strategies to improve the adaptability of water security systems.

Published: September 2017

The optimization and management of an integrated urban wastewater system is a complex problem involving many processes and variables. The possible control options are defined by several management strategies that may differently impact the economic, operational or environmental performance of the system. The present paper aims to contribute to the environmental and energy sustainability of urban wastewater systems by means of a multicriteria performance analysis. The paper begins with a complete analysis of the system performance in several fields of interest (energy, environment, quality of service, operation, economy and financial resources), and it highlights the management strengths and weaknesses in each subsystem. The analysis was carried out by means of a prototype, developed during the ALADIN project, which enables understanding the system, planning effective improvement actions and assessing their possible effects in each part of the urban water cycle. To demonstrate the potential of such an approach, it was tested on an actual integrated urban wastewater system in Sicily.

Drinking water related infections are expected to increase in the future due to climate change. Understanding the current links between these infections and environmental factors is vital to understand and reduce the future burden of illness. We investigated the relationship between weekly reported cryptosporidiosis and giardiasis (n = 7,422), extreme precipitation (>90th percentile), drinking water turbidity, and preceding dry periods in a drinking water system located in greater Vancouver, British Columbia, Canada (1997–2009) using distributed lag non-linear Poisson regression models adjusted for seasonality, secular trend, and the effect of holidays on reporting. We found a significant increase in cryptosporidiosis and giardiasis 4–6 weeks after extreme precipitation. The effect was greater following a dry period. Similarly, extreme precipitation led to significantly increased turbidity only after prolonged dry periods. Our results suggest that the risk of cryptosporidiosis and giardiasis increases with extreme precipitation, and that the effects are more pronounced after a prolonged dry period. Given that extreme precipitation events are expected to increase with climate change, it is important to further understand the risks from these events, develop planning tools, and build resilience to these future risks.

Published: September 2017

Dairy wastewater contains high levels of organics and other pollutants. The present study was carried out to investigate the biodegradation process of dairy effluents using some locally isolated bacteria and fungi. Four different dairy effluent samples were collected from Obour and 6th October industrial cities, Egypt. Five bacterial species (Pseudomonas aeruginosa, Bacillus subtilis, Lactobacillus delbrueckii, Staphylococcus aureus and Enterococcus hirae) and three fungal strains (Alternaria sp., Fusarium sp. and Aspergillus sp.) were isolated from dairy wastewater samples, identified and used for biodegradation process. Bacterial and fungal consortia were prepared separately in the laboratory. Two-stages (aeration and filtration) laboratory scale model was designed. Rice straw and activated carbon layers were used as filtration media. Results indicated the great ability of both studied bacteria and fungi for removal of organics (biological oxygen demand removal percent were 78.7% and 74.7% for bacteria and fungi, respectively) and the improvement of the physicochemical quality (total suspended solids removal percent were 99.3% and 99.0% for bacteria and fungi, respectively) of the dairy effluent. The addition of rice straw and activated carbon increased removal efficiencies. Biodegradation of dairy wastewater depending on local microorganisms is an effective, cheap and eco-friendly technology.

In short time, Indonesian digital poetry attracts its audience through a series of visualization features of the digital art. This research uses a short segment analysis on Indonesian videography digital poetry to demonstrate the existence of visual conglomeration practices through the creation of objects, features, a feature of space, measuring distance in feature space, and dimension reduction. These five approaches are proposed by Manovich (2014) in ​​grouping millions of visual artworks based on simple criteria. Of the three common objects are found, Indonesian animators, prefer individuals and texts as the main impression. The movement features are found in cinematic poetry and its rely depend on kinetic texts. Meanwhile, non-movement features can be found in the form of human imitation or part of them, portraits, silhouettes, and comics. Indonesian digital poetry of space features in form of textual space is prioritizing on the kinetics text, the space of time is prioritizing the presentation of objects association of words are spoken, the neutral space is prioritizing the use of computer technology application. The grouping of visual art composition is based on two criteria: the technique of creating and artistic impressions. The dimensional reducing is prominently practiced by Afrizal Malna.

Authors: Ríos Flores Jesús Armando , Ocegueda Hernández Juan Manuel
Published: September 2017

Este estudio presenta un análisis sobre el efecto de la capacidad innovadora en el crecimiento económico bajo un marco espacio-temporal. Al reconocer las limitantes de la representatividad de la propiedad intelectual en las regiones institucionalmente débiles, se genera un indicador agregado para la capacidad innovadora mediante un modelo factorial, que permita comparar los efectos de ambos indicadores. Los resultados muestran que la capacidad para innovar, en el caso de las patentes, sólo es significativa en presencia de efectos espaciales, mientras el indicador agregado es significativo en todos los casos, y es aún mayor cuando el efecto espacial es relevante.

Las infraestructuras de transporte carretero son elementos vertebradores del territorio e influyen en el desarrollo socioeconómico. Esta investigación consideralos supuestos que establece la Teoría de Utilidad Aleatoria (TUA) para describir las características que influyen en la localización manufacturera mediante el empleo de modelos lineales generalizados. El análisis empírico considera la Región Bajío de México. Los resultados muestran que el potencial de accesibilidad debe considerarse directamente proporcional al tiempo de viaje e inversamente proporcional al tamaño del mercado para que sea acorde a la TUA. Además, dicha accesibilidad induce un impacto significativo pero no determinante por sí mismo.
Da marginalidade à segregação: contribuições de uma teoria urbana crítica
Authors: Simoni Santos César
Published: September 2017

Muitas interpretações a respeito das dinâmicas da globalização colocaram o elemento urbano no centro do debate. Como as condições de elaboração da sociedade urbana vinculam-se muito mais diretamente a aspectos extra-regionais, o processo teria carregado o potencial de destituição do caráter local de algumas manifestações sociais específicas e, por consequência, tornaria-se exigente de um renovado tratamento conceitual. Esse movimento parece ter atingido o conceito de segregação. No momento em que o mundo parece experimentar a fratura social que até então serviu como elemento de caracterização da especificidade regional da América Latina, torna-se pertinente reconsiderar o debate local sobre a marginalidade.

Published: September 2017

En Latinoamérica, la producción social de la vivienda ha sido una solución de facto frente a la incapacidad de los gobiernos para crear las condiciones institucionales que permitan una provisión plena de la vivienda a todos los sectores de la sociedad. Este modelo de producción se podría calificar de eficaz, pues en países como México ha producido más de la mitad de las viviendas, sin embargo, se torna un proceso ineficiente por su condición de informalidad. En este artículo se evalúan dos casos de producción social formal de la vivienda para determinar su efectividad y factores de éxito.

Published: September 2017

Se analiza la experiencia de beneficiarias del programa Microempresas Sociales (MES) que opera en Chiapas desde 2001, a partir de los conceptos de pobre (sujeto), pobreza (contexto) y empobrecimiento (proceso), propuestos por Vega-Estrada. Los resultados muestran que el papel de los microcréditos en la erradicación de la pobreza se ha sobrevalorado y que, si bien pueden contribuir a revertir el proceso de empobrecimiento, no inciden en el problema estructural de la pobreza. Con esto esperamos contribuir a la discusión en torno a si el microcrédito femenino es una herramienta efectiva de combate a la pobreza.

Cuando la cleptocracia no alcanza: los delitos contra las empresas
Authors: Vilalta Perdomo Carlos Javier
Published: September 2017

¿Cuántos delitos contra las empresas se cometen y cuál es el daño económico que producen? Con este estudio se responde esta pregunta, y se agrega un análisis inicial estadístico de diversas características elementales de este problema de seguridad pública. Con base en las encuestas de victimización contra las empresas de 2011 y 2013 en México realizado por el Instituto Nacional de Estadística y Geografía (Inegi), se encontró, principalmente, que las pérdidas económicas directas y los gastos destinados en medidas de protección contra el delito son multimillonarias. Otro problema claramente identificable es la alta victimización empresarial por actos de corrupción, en donde los victimarios son funcionarios de gobierno.
De repórter de combate a operador ideológico: John Reed em Reed, México Insurgente (1972)
Authors: Lobo Júlio César
Published: September 2017

O objetivo desse texto é analisar o filme mexicano  de ficção Reed, México insurgente (1972), de Paul Leduc, evidenciando os seguintes aspectos: a sua singularidade como um filme de guerra civil na cinematografia latino-americana, tendo um repórter norte-americano, John Reed, como sua personagem condutora, a sua postura documentarizante, a sua recusa a uma espetacularização de combates e uma representação rara de Pancho Villa sem estereotipagem e a sua primazia na dramatização da subjetividade do seu protagonista, destacando os seus medos, as suas angústias, as suas inseguranças no campo de batalha. Em seu vínculo mais forte com o cinema político que se fazia no começo dos anos 1970 na América Latina, principalmente no seu Cone Sul, essa película mexicana lentamente constrói a passagem de Reed de repórter de combate a observador participante e ao final, a um operador ideológico. Enfim, trata-se de uma obra rara na filmografia latino-americana dos anos 1970 e depois: a representação de uma paixão por um ideal.

The river engineering works there were done by building cable block ramp. The studied reach was located in the Czarny Dunajec river. Analyzed reach of the river consisted of 100-m long segment upstream of the existing block ramp and 65 m downstream of it. The analysis was done based on field measurements, numerical modeling with HEC-RAS and Hjulström’s graph. Numerical modeling was conducted for observed flood Qfl ood = 16.9 m3·s–1 on 5 August 2013, and for the t-years floods: Q50% = 59 m3·s–1, Q25% = 99 m3·s–1, Q10% = 165 m3·s–1 and Q1% = 321 m3·s–1. For the analyzed reach an attempt was done to determinate dominant discharge.

Nowadays, gadged just like handphone and notebook more reachable so the quantities of the users are increase in Indonesia. It is common for us to see the students, employees, enterpreneurs until housewives using gadged anywhere and anytime. This phenomenon is spread widely along with the internet wifi and hotspot in many places start from official educational institute, government, and office centre, to the tourism object and shopping center. Also with internet café (Warnet) compete tightly with offering various facilities, and services with compete price. All cellphone service is also giving internet access in order to attract users. Some phenomena show more and more people who use the Internet and make it as a lifestyle for berintaksi, socialize, learn and get information. Widespread use of the Internet can be a great potential in the development of online learning system allows learners to access the information flexibly without limitation of time and place. Discussion no longer occur face to face, but can continue even in the virtual environment. As the implementation of other virtual learning methods. Implementation of online discussion itself is basically adopting the method of learning face to face discussionHarga gadged seperti handphone dan  dan  notebook kian hari kian terjangkau sehingga jumlah penggunanya di indonesia terus meningkat. Bukan lah suatu yang asing jika kita menjumpai para siswa, mahasiswa, karyawan, pengusaha hingga ibu rumah tangga menggunakan gadged di mana saja dan kapan saja. Fenomena ini diiringi dengan meluasnya jaringan internet nirkabel seperti hotspot  dan  wifi di berbagai tempat mulai dari institusi  resmi pendidikan, pemerintahan, dan perkantoran, hingga tempat wisata,dan pusat perbelanjaan. Tidak mau ketinggalan warnet (warung internet) ikut bersaing ketat dengan menawarkan berbagai macam fasilitas, dan layanan dengan harga bersaing. Seluruh layanan seluler ponsel juga terus memberikan penawaran akses internet yang menggiurkan demi menarik minat penggunanya. Beberapa fenomena tersebut menunjukkan semakin banyak kalangan yang memanfaatkan internet dan menjadikanya sebagai gaya hidup untuk berintaksi, bersosialisasi, belajar dan mendapatkan informasi. Meluasnya pemanfaatan internet bisa menjadi potensi besar dalam pengembangan pembelajaran dengan sistem online memungkinkan pebelajar untuk mengakses infromasi secara fleksibel tanpa terbatas waktu dan tempat. Diskusi tidak lagi terjadi secara tatap muka, namun dapat terus berlangsung meskipun dalam lingkungan maya. Sebagaimana pelaksanaan metode pembelajaran maya lainnya. Pelaksanaannya diskusi online itu sendiri pada dasarnya mengadopsi dari metode pembelajaran diskusi tatap muka.
