Introducing a learning management system at a Russian university: Students' and teachers' perceptions
Authors: Emelyanova Natalya , Voronina Elena 
Published: September 2016

<p class="BODYTEXT">Learning management systems (LMS) have been proven to encourage a constructive approach to knowledge acquisition and support active learning. One of the keys to successful and efficient use of LMS is how the stakeholders adopt and perceive this learning tool. The present research is therefore motivated by the importance of understanding teachers' and students' perceptions of LMS in order to anticipate possible issues (problems) and help to build a productive learning environment and a committed user community. The paper looks at this process at a Russian university (National Research University Higher School of Economics – HSE) where the system is being implemented and examines the following issues: qualification and readiness of the stakeholders to use LMS and their perceptions of the system's convenience, effectiveness, and usefulness. The research reveals remarkable divergence of students’ and teachers’ perceptions of various aspects of LMS which must be considered when raising the effectiveness of the system and building commitment to e-learning. They are analyzed and explicated in the present paper.</p><p class="BODYTEXT"><span lang="EN-US"><br /></span></p>
Promoting reflection in asynchronous virtual learning spaces: Tertiary distance tutors’ conceptions
Authors: Alden Rivers Bethany Alden , Richardson John T. E. , Price Linda 
Published: September 2016

<p>Increasingly, universities are embedding reflective activities into the curriculum. With the growth in online tertiary education, how effectively is reflection being promoted or used in online learning spaces? Based on the notion that teachers’ beliefs will influence their approaches to teaching, this research sought to understand how a group of distance tutors at the UK Open University conceptualised reflection. It was hoped that these findings would illuminate their approaches to promoting reflection as part of their online pedagogies. Phenomenographic analysis indicated that these tutors conceptualised reflection in four qualitatively different ways. Furthermore, the data suggested that these educators held a combination of two conceptions: one that understood the origin of being reflective and one that understood the purpose of reflection. Analysis of structural aspects of these conceptions offered insight into tutors’ own perspectives for what is needed to make online learning environments fertile territory for reflective learning. </p>

Published: September 2016

<p>This study intends to explore the current trends in the field of distance education research during the period of 2009-2013. The trends were identified by an extensive review of seven peer reviewed scholarly journals: <em>The American Journal of Distance Education</em> (AJDE), <em>Distance Education</em> (DE), <em>The European Journal of Open, Distance and e-Learning</em> (EURODL), <em>The Journal of Distance Education</em> (JDE), <em>The Journal of Online Learning and Technology</em> (JOLT), <em>Open Learning: The Journal of Open, Distance and e-Learning</em> (OL) and <em>The International Review of Research in Open and Distributed Learning</em> (IRRODL). A total of 861 research articles was reviewed. Mainly content analysis was employed to be able to analyze the current research. Also, a social network analysis (SNA) was used to interpret the interrelationship between keywords indicated in these articles. Themes were developed and the content of the articles in the selected journals were coded according to categories derived from earlier studies. The results were interpreted using descriptive analysis (frequencies) and social network analysis. The reporting of the results were organized into the following categories: research areas, theoretical and conceptual frameworks, variables, methods, models, strategies, data collection and analysis methods, and the participants. The study also identified the most commonly used keywords, and the most frequently cited authors and studies in distance education. The findings obtained in this study may be useful in the exploration of potential research areas and identification of neglected areas in the field of distance education. </p>
Learners’ goal profiles and their learning patterns over an academic year
Authors: Ng Clarence 
Published: September 2016

<p>The present study aimed to examine distance learners’ goal profiles and their contrasting patterns of learning and achievements at three different points during an academic year, i.e. in the beginning of the course in relation to learners’ general orientations to learning, at the middle of the course in relation to learners’ completion of an assignment, and towards the end of the course in relation to learners’ preparation for course examination. Two hundred seventy-six adult distance learners completed three survey questionnaires that assessed their motivation and learning at these three learning points. Using person-centred analytical procedures, this study located four groups of learners based on different combinations of mastery and performance-approach goals. MANOVA results have shown that multiple-goal learners (High mastery/High performance, HH) who held strong mastery and performance-approach goals used more deep and regulatory strategies and showed a higher level of learning interest across three waves of surveys than did those focusing solely on mastery (HL) or performance-approach goals (LH). However, the multiple-goal learners did not have better achievement levels compared to those focusing solely on mastery goals (HL). Given that multiple goal learners learnt with a more engaged pattern, it is less likely that these motivated learners will drop out of distance learning courses and programs. Future studies should explore how these goals can be promoted simultaneously in distance learning.</p>
Developing, using, and interacting in the flipped learning movement: Gaps among subject areas
Authors: Chen Hsin-liang , Summers Kevin L. 
Published: September 2016

<p>The purpose of this paper is to investigate the current video collection of an open-access video website (TED-Ed). The research questions focus on its content as evidence of development, its viewership as evidence of use, and flipping as evidence of interaction in informal learning. In late September 2013, 686 video lessons were posted on the TED-Ed website that spanned 12 academic subject categories and 60 academic subject subcategories, as labeled and sorted on the TED-Ed website itself. The findings of the analysis of the TED-Ed video collection indicate several gaps in the humanities, social science, and natural science academic areas in terms of the number of video lessons and viewership. Despite the gaps in the numbers of video lessons and the viewership across those three academic areas, the areas have very similar averages of daily flipped lessons. The future research agenda should focus on the motivation of viewers to create flipped lessons as evidence of learning in an open learning environment. </p>
University of Toronto instructors’ experiences with developing MOOCs
Authors: Najafi Hedieh , Rolheiser Carol , Harrison Laurie , Håklev Stian 
Published: September 2016

<p>We interviewed eight University of Toronto (U of T) instructors who have offered MOOCs on Coursera or EdX between 2012 and 2014 to understand their motivation for MOOC instruction, their experience developing and teaching MOOCs, and their perceptions of the implications of MOOC instruction on their teaching and research practices. Through inductive analysis, we gleaned common motivations for MOOC development, including expanding public access to high quality learning resources, showcasing U of T teaching practices, and attempting to engage MOOC learners in application of concepts learned, even in the face of constraints that may inhibit active learning in MOOC contexts. MOOC design and delivery was a team effort with ample emphasis on planning and clarity. Instructors valued U of T instructional support in promoting systematic MOOC design and facilitating technical issues related to MOOC platforms. The evolution of MOOC support at U of T grew from a focus on addressing technical issues, to instructional design of MOOCs driven, first, by desired learning outcomes. Findings include changes in teaching practices of the MOOC instructors as they revised pedagogical practices in their credit courses by increasing opportunities for active learning and using MOOC resources to subsequently flip their classrooms. This study addresses the paucity of research on faculty experiences with developing MOOCs, which can subsequently inform the design of new forms of MOOC-like initiatives to increase public access to high quality learning resources, including those available through U of T.</p>
The Role of Social Media for Collaborative Learning to Improve Academic Performance of Students and Researchers in Malaysian Higher Education
Authors: Al-Rahmi Waleed , Othman Mohd Shahizan , Yusuf Lizawati Mi 
Published: September 2016

<p>Social media is widely considered to improve the collaborative learning among students and researchers. However, there is a surprising lack of empirical research in Malaysian higher education to improve performance of students and researchers through the effective use of social media that facilitates desirable outcomes. Thus, this study offers a review of the empirical literature, and its distinctiveness stems from the focus on collaborative learning and engagement in literature, as dominated by higher education. This study also aims to explore factors that contribute to the enhancement of collaborative learning and engagement through social media. It is also unique in that it highlights that the effective use of social media depends on users in what is referred to as social interactivity to "collaborative learning, engagement and intention to use social media" - a phenomenon that relies on the theory of social constructivist learning. The findings showed that collaborative learning, engagement and intention to use social media positively and significantly relate to the interactivity of research group members (students and researchers) with supervisors to improve their academic performance in Malaysian higher education.<strong></strong></p>
An Investigation of University Student Readiness towards M-learning using Technology Acceptance Model
Authors: Iqbal Shakeel , Ahmed Bhatti Zeeshan 
Published: September 2016

<p>M-learning is<strong> </strong>learning delivered via mobile devices and mobile technology. The research indicates that this medium of learning has potential to enhance formal as well as informal learning. However, acceptance of m-learning greatly depends upon personal attitude of students towards this medium; therefore this study focuses only on the individual context in which role of student’s readiness towards m-learning is investigated using Technology acceptance model (TAM). TAM is the popular choice among the researchers for investigating acceptance of any new technology primarily because of its robust and parsimonious nature. The sample selected for this study consisted of students from the private sector universities in a developing country. A structured questionnaire was used for data collection. The final results of investigation were based on 244 valid responses. The results indicate that the students’ skills and psychological readiness strongly influence their perceived ease of use (PEU) and perceived usefulness (PU) of m-learning, whereas both these constructs positively influenced their behavioral intention to use m-learning. The findings of this study have theoretical as well as practical implications which are discussed at the end.</p>

Published: September 2016

Hama Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae) merupakan hama penting pada tanaman bawang di Indonesia. Pengendalian hama ini dengan insektisida kimia sintetik tidak memuaskan, bahkan telah menyebabkan hama menjadi resisten. SeNPV bila diaplikasikan secara tunggal untuk pengendalian hama S. exigua hasilnya masih kurang memuaskan. Namun, diharapkan SeNPV bila dicampurkan dengan insektisida botani dapat memberikan hasil yang lebih baik untuk mengendalikan hama S. exigua. Penelitian bertujuan mengetahui potensi campuran SeNPV dengan insektisida botani terhadap mortalitas larva S. exigua instar 3 di laboratorium. Percobaan dilaksanakan di Laboratorium Entomologi Balai Penelitian Tanaman Sayuran, Lembang ( ± 1.250 m dpl.), mulai bulan Juli sampai Oktober 2014. Larva S. exigua dikumpulkan dari pertanaman petani bawang merah di daerah Cirebon, Jawa Barat dan diperbanyak di Rumah Kasa Balai Penelitian Tanaman Sayuran. Penelitian dilaksanakan dalam dua tahap kegiatan, yaitu (1) uji pendahuluan dosis SeNPV dan empat jenis ekstrak tumbuhan, yaitu legundi (Vitex trifolia Linn.), serai wangi (Cymbopogon nardus), daun jeruk purut (Citrus hystrix DC), ubi gadung (Dioscorea hispida) dan (2) uji campuran beberapa dosis SeNPV dengan dosis sublethal dari ekstrak daun legundi (Vitex trifolia Linn.). Rancangan percobaan yang digunakan ialah rancangan acak lengkap yang terdiri atas enam perlakuan dan empat ulangan. Mortalitas larva S. exigua diamati mulai 24 jam sampai dengan 168 jam setelah perlakuan. Data mortalitas larva diolah menggunakan analisis probit untuk menetapkan nilai LC50. Hasil analisis menunjukkan bahwa nilai LC50 SeNPV sebesar 424,67 ppm dan dari empat ekstrak insektisida botani yang terendah diperoleh dari insektisida daun legundi, yaitu 2.199, 277 ppm. Berdasarkan nilai LC50 campuran SeNPV dengan insektisida botani daun legundi menunjukkan efektivitas sinergistik dan meningkatkan efikasi 12,24 kali lipat jika dibandingkan dengan SeNPV secara tunggal. Kombinasi SeNPV dengan ekstrak daun legundi konsentrasi sublethal dapat meningkatkan efikasi virus SeNPV dalam mengendalikan S. exigua.

Summary
Because of the effect of reservoir heterogeneity and fractures in low-permeability reservoirs, effective characterization of waterflood direction and front has become a challenging issue under high-water-cut condition. To achieve better understanding of such a complex problem, a work flow, containing statistical and numerical techniques, is developed to characterize waterflood direction and front distribution in Changqing oilfield by using both flow rates and bottomhole-pressure (BHP) data. The work flow includes four steps: First, dynamic analysis is used to qualitatively investigate the relationships between injector and producers; then, the constraint multiple-linear-regressions (MLR) method is applied to calculate the interwell-connectivity coefficients, which was used to quantitatively describe the waterflood direction by production and injection rates. On the basis of the results of the two former steps, we can adopt numerical well testing as our third step to deal with flow rates and BHP data to characterize the waterflood direction and front. Finally, the streamline method is used to simulate the waterflood front and high-permeability-channel distribution on the basis of the outcome of the three preceding techniques.
Compared with individual methods, the proposed work flow can offer more perspectives and ways to make a comprehensive and deep investigation of the waterflood reservoir. The results obtained by this work flow enable proactive and better waterflood management in the Well Group W16 in Changqing oil field; namely, the water cut of producers decreases, meanwhile the oil production increases by nearly 40% referring to the field data in 2015. With the help of the information obtained by this work flow, operators could make more-reasonable decisions on waterflood management such as well-pattern optimization and injection–production parameters adjustment.

Published: September 2016

In our research we have to open the contents of aesthetic taste. It is determined historically and connected to the various political, ideological and religious sides of life a society. The concept of taste reflects the metaphysics maintained by culture. Totalitarian taste – derivative the totalitarian state. Propagation of optimism, flatter realism, photographic concreteness, staging of official ceremonies, and private life has transformed art of this time into a mix of a forgery with heroism, that equally forged culture of people, and also had destructive effect on an aesthetics and ethics of the silent majority. In papers we attempt to determine the basic attributes of totalitarian taste is made within the framework of aesthetic interpretation of creativity of the Russian artist of the beginning of XX century – K.S.Petrov-Vodkin.
Estudo sobre a influência da permeabilidade no meio poroso em projetos de injeção e armazenamento geológico de CO2
Authors: ZUCATELLI PEDRO JUNIOR 
Published: September 2016

Um dos objetivos da simulação numérica em reservatórios de petróleo e aquíferos salinos está voltado à previsão do comportamento dos mesmos ao longo de sua vida. Uma das mais importantes propriedades petrofísicas para qualificação desses meios porosos é a permeabilidade. A permeabilidadede um meio poroso é a medida de sua capacidade de deixar atravessar por fluidos. O presente artigo aborda um estudo envolvendo simulações de injeção e armazenamento geológico de CO2 em um aquífero salino a fim de analisar o comportamento do reservatório com a variação da permeabilidade. O modelofísico estudado foi um reservatório fictício em formato de paralelepípedo cuboide possuindo um poço injetor localizado no seu centro. Considerou-se o escoamento tridimensional, moderadamente compressível e multifásico com fluxo transiente. Para tal estudo, foi utilizado o software Eclipse da empresa Schlumberger para realizar simulações de três estudos de caso, em que a permeabilidade é aumentada e reduzida. O primeiro caso trata-se de um modelo simulado que se torna o padrão para comparar e caracterizar com o segundo e o terceiro caso. Os resultados foram comparados e interpretadosbaseando-se na variação da pressão e da saturação de gás no aquífero salino. Conclui-se nesse artigo que ambos os parâmetros analisados são mais sensíveis a redução da permeabilidade.
