A framework for developing competencies in open and distance e-learning
Authors: Arinto Patricia B
Published: November 2016

Many open universities and distance education institutions have shifted from a predominantly print-based mode of delivery to an online mode characterised by the use of virtual learning environments and various web technologies. This paper describes the impact of the shift to open and distance e-learning (ODeL), as this trend might be called, on the course design practices of faculty members at a small single-mode distance education university in the Philippines. Specifically, the paper presents and analyses the faculty’s perspectives on how their course design practices have changed and issues and challenges arising from these changes. The findings suggest that faculty training programs in ODeL should aim to develop a comprehensive range of ODeL competencies in a systematic and coherent way. Based on the findings, as well as research on practitioner development in teaching effectively with technology, a framework for developing ODeL competencies among faculty is proposed. Aside from covering the four areas of change in course design practice identified in the study, the framework also specifies levels of expertise (basic, intermediate, and advanced), indicating degrees of complexity of the knowledge and skills required for each area at each level. All of the competencies listed for all four areas at the basic level comprise the minimum competencies for teaching an online distance education course.
Moving to open educational resources at Athabasca University: A case study
Authors: Ives Cindy , Pringle Mary Margaret
Published: November 2016

Since the birth of the World Wide Web, educators have been exchanging ideas and sharing resources online. They are all aware of the turmoil in higher education created by freely available content, including some hopeful developments charted in this issue. Interest has grown steadily over the past decade in making a university-level education openly available to students around the globe who would otherwise be overlooked, and recommendations for how to do this are well documented (e.g., UNESCO, 2002; OECD, 2007). Initiatives in the United States (Thille, 2012), Canada (Stacey, 2011b), Africa (OER Africa, n.d.), and the United Kingdom (JISC, 2012) are easily accessed and case studies abound (e.g., Barrett, Grover, Janowski, van Lavieren, Ojo, & Schmidt, 2009). Supporting the widespread availability of OER is a goal that Athabasca University (AU) has embraced through association with the Commonwealth of Learning and by becoming a charter member of the OER University (OERu, 2011). The use of OER in AU programs has strategic local implications that go beyond the five reasons for institutions to engage in OER projects described by Hylén (2006). Recently at AU explorations have begun into the potential of using OER in course design and production.
The logic of national policies and strategies for open educational resources
Authors: Mulder Fred
Published: November 2016

In its first decade (2001-2010) the OER movement has been carried by numerous relevant and successful projects around the globe. These were sometimes large-scale but more often not, and they were primarily initiated by innovating educational institutions and explorative individual experts. What has remained, however, is the quest for a sustainable perspective, in spite of the many attempts in the OER community for clear-cut solutions to the problem of sustainability. This is a major barrier for mainstreaming the OER approach in national educational systems.

At the end of the first decade, and more so at the beginning of the second decade (2011-2020), we are witnessing in a few countries emerging efforts to develop and establish a national OER approach. That is required in order to break down the barrier for mainstreaming OER. Making the OER approach sustainable cannot be left to the educational institutions only, but should be facilitated in a national setting.
Challenges for successful planning of open and distance learning (ODL): A template analysis
Authors: Minnaar Ansie
Published: November 2016

How to plan an open and distance learning (ODL) unit in higher education is not clearly described in the literature. A number of ODL facilities at residential universities have not been successful because of a lack of planning or because of failure to ensure that all the different systems for ODL delivery were in place and functioning. This paper sheds light on how to plan strategically and how to implement an ODL unit at an existing university.

A template analysis was used to construct a road map for ODL planners. We used this analytical tool to organise data from a large collection of articles, books, and documents from 1980-2010. We purposefully chose template analysis as a document analysis process to foster the recurring themes found in published articles on planning and implementing ODL facilities in higher education.

The results indicate four main strategies for successful implementation of an ODL unit. The template consists of strategic planning, policies, systems, and challenges. It was concluded that the template for ODL planning offers new insight into distance education. It could be used as a foundation for ODL planning, implementation, monitoring, and evaluation. We recommend further research on the template with the aim of theory construction for ODL planning and implementation.
Enhancing motivation in online courses with mobile communication tool support: A comparative study
Authors: Chaiprasurt Chantorn , Esichaikul Vatcharaporn
Published: November 2016

Mobile technologies have helped establish new channels of communication among learners and instructors, potentially providing greater access to course information, and promoting easier access to course activities and learner motivation in online learning environments. The paper compares motivation between groups of learners being taught through an online course based on an e-learning system with and without the support of mobile communication tools, respectively. These tools, which are implemented on a mobile phone, extend the use of the existing Moodle learning management system (LMS) under the guidance of a mobile communication tools framework. This framework is considered to be effective in promoting learner motivation and encouraging interaction between learners and instructors as well as among learner peers in online learning environments. A quasi-experimental research design was used to empirically investigate the influence of these tools on learner motivation using subjective assessment (for attention, relevance, confidence, satisfaction, and social ability) and objective assessment (for disengagement, engagement, and academic performance). The results indicate that the use of the tools was effective in improving learner motivation, especially in terms of the attention and engagement variables. Overall, there were statistically significant differences in subjective motivation, with a higher level achieved by experimental-group learners (supported by the tools) than control-group learners (unsupported by the tools).

Published: November 2016

The aim of this work is to present a design approach of a Shock-Induced Combustion Ramjet (Shcramjet) inlet, and present its optimization in terms of the flow and geometrical parameters. The flow properties of mixed compression type inlet of a Shcramjet are examined using analytical and numerical techniques. The geometries obtained with variations in the wedge angles, length, height and cowl lip positions are used to study the flow characteristics of inlet, identifying bow shock temperature ratio as the optimization parameter. The two-dimensional geometries of two-shock and three-shock inlet models designed analytically for shock-on-lip condition at Mach 12.5 and an altitude of 32.5 km are numerically simulated in OpenFOAM CFD Toolbox. A density based compressible CFD solver based on central upwind schemes of Kurganov and Tadmore is used to solve 2D inviscid Euler equations. The inlet total pressure recovery is expressed as a function of temperature ratios of compression shocks, and is found to have a maxima at a bow shock temperature ratio at the design condition when the bow and external shocks have equal strengths. The effect of considering the flow to be calorically imperfect is studied numerically, and the deviation from the analytical design is presented.

Published: November 2016

This paper proposes a personal-value based item modeling, which is used for calculating predicted ratings and for explaining recommendation. Personal value is one of factors affecting our decision making, and its application to recommender systems has been studied recently. This paper extends existing personal values-based user modeling to item modeling, which estimates characteristics of reviewers who like / dislike target items. A method for calculating predicted ratings based on obtained personal values-based item models is also proposed. Furthermore, this paper focuses on explanation of recommendation as well, which is one of challenges in the recent study of recommender systems. Improvements of user’s satisfactions for recommender systems by showing process of recommendation gets to be important in addition to precision of recommendation. A recommender system is developed based on the proposed method, of which effectiveness is evaluated by a user experiment, in which the target items are movies. Experimental results showed the effectiveness of the proposed method including recommendation accuracy and an explanation of recommendation. It is also shown that the proposed recommender system has the potential to recommend long-tail items.

The context search engine has been studied for answering trend-related queries. As trend information is obtained from temporal data, which is common in many applications, the context engine is expected to be available regardless of domains. When using existing search engines, it is supposed that users submit a series of queries based on search intention. Therefore, search functions of the context search engine should be designed based on the user’s potential search intention. To analyze user’s behavior in information retrieval, this paper conducted experiments using existing Web search engines. The experimental result is analyzed, based on which the design of a context search engine is described. As another contribution of this paper, new types of temporal variations which can be used to specify queries of the context search engine are also proposed. The results of user experiments confirmed the usability of the proposed temporal variations.

Published: November 2016

Biped locomotion created by a controller based on Zero-Moment Point (ZMP) known as reliable control method looks different from human’s walking on the view point that ZMP-based walking does not include falling state, and it’s like monkey walking because of knee-bended walking profiles. However, the walking control that does not depend on ZMP is vulnerable to turnover. Therefore, keeping the event-driven walking of dynamical motion stable is important issue for realization of human-like natural walking. In this research, a walking model of humanoid robot including slipping, bumping, surface-contacting and line-contacting of foot is discussed, and its dynamical equation is derived by the Extended NE method. In this paper we introduce the humanoid model which including the slipping foot and verify the model.

Microseismic Closure Window Characterizes Hydraulic-Fracture Geometry Better
Authors: Liu Songxia , Valkó Peter P. , McKetta Steven , Liu Xiaoda
Published: November 2016

Many studies have assessed microseismic (MS) interpretation in hydraulically fractured shale wells. However, to derive stimulated reservoir volume (SRV) and fracture geometry from MS data is still enigmatic, because MS events come not only from the induced main fractures of the current stage, but also from nonrelevant sources. MS data of adjacent stages tend to overlap each other severely. Simulated hydraulic-fracture (HF) networks that use MS data always yield higher production than actually reported. We addressed these issues by evaluating MS data from the “closure window.”

With an in-house Excel-VBA program, we divided the MS events from each fracture stage into three windows: the pad window, the proppant window, and the closure window, on the basis of the fracture-stimulation record of each stage. The closure window includes only MS events during the shut-in period (from the end of slurry pumping until before flowback of that stage). During the closure window, leakoff and fracture closing are the dominant phenomena. Leakoff into the formation matrix can cause shear slippage of pre-existing natural fractures (NFs) and tensile opening of micropores. These secondary fractures have potential to transport fluid and to facilitate the induced major fractures. The fracture will close when the fluid inside leaks off. Both leakoff and fracture closing can trigger MS events near the major fractures; thus, they can better capture the effective fracture geometry of the current stage.

This method was applied on five shale wells. Unique characteristics in the closure window were observed. The closure window reduced the fracture dimensions of each stage and MS-cloud overlap among stages. Comparing the closure window with the entire window, one finds that fracture width (Wf) decreased the most by an average of 230 ft (26.6%), fracture height (hf) decreased by an average of 89.6 ft (25.7%), and fracture length (xf) decreased by an average of 41.6 ft (4.9%). The three windows shifted from each other, with closure window shifting from the previous stages. Cumulative-production history-match error dropped from 30% in the entire window to 2% in the closure window. With the closure window, we eliminated those events induced by previous stages, reactivation of NFs, and pumping noise detected by Pad and proppant windows. We suggest that closure window MS data, collected after proppant pumping, provide unique insights into fracture stimulation.

The method and VBA program developed in this study can be used to process MS data from any fracture-stimulation job, to segregate the three MS event windows. The MS closure window will indicate fracture geometry more accurately, and thus enhance optimization of hydraulic-fracturing design and the prediction of hydrocarbon production. Infill wells and refracturing may be considered in the light of indicated fracture-geometry reduction.

Abuja Master Plan provided development of adequate Green Areas and other Recreational Facilities within the Federal Capital City (FCC), as part of its sustainability principles and provided for these recreational facilities within each neighborhood (FCDA, 1979). However, there have been several recent foul cries about the negative development of recreational facilities and the abuse of the Master Plan in the FCC.  The motivation for carrying out this study arose from the observation that recreational facilities in Phase 1 of the Federal Capital City Abuja are not clearly developed as intended by the policy makers and thus, the need to identify the recreational facilities in the Phase 1 of FCC and observe their level of development as well as usage. The field survey revealed that the Central Business District and Gazupe have higher numbers of recreational facilities with 45 and 56. While Wuse II (A08) and Wuse II (A07) Districts have lesser recreational facilities with 10 and 17. The field survey further revealed that all the districts in Phase 1 have over 35% cases of land use changes from recreational facilities to other use. The survey shows that over 65% of these recreational facilities are fully developed. The study also shows that just about 11% of the recreational sporting facilities were developed in line with the Abuja Master Plan in Phase 1. The study revealed that recreational facilities in Phase 1 of the FCC, Abuja has not being developed in compliance with the Abuja Master Plan.

Many towns in Uganda are growing at an unprecedented rate. By 2030 more than 50% of Ugandans will beliving in urban centres. This rapid growth of urban centres in Uganda provides for economic opportunities for manyurban residents. It also poses various challenges such as urban sprawl, emergence of informal settlements as well asurban poverty. Over 60% of the urban residents in Uganda live in the informal settlements with no basic services andinfrastructure such as piped water, decent housing, good roads, sewerage systems as well as schools and health centres.This paper aims to examine and understand the constraints to urban planning and management of secondary towns inUganda. Using an eclectic mix of research methods such as face to face interviews targeting key informants, a questionnairesurvey as well as observation, the study found that the current modernist planning approach has not achieved itsintended goal of promoting orderly urban development and improve service delivery in the secondary towns. The studyalso revealed that the urban residents are rarely involved in planning. Besides, there is an apparent mismatch betweenwhat is taught at the local planning schools and what is required in terms of planning in the secondary towns. To addressthese intractable urban challenges, it is critical that the current planning education and curriculum are reviewed to producecreative and imaginative planners that can respond more effectively to the community problems, adopt a strategyto promote strategic spatial planning that is more participatory, carry out public awareness campaigns about the need forproper planning of towns and adopt a strategy for promoting innovative funding programmes such as municipal bonds,use of the stock exchange to mobilise the required investable funds, allow the private sector to access institutional fundssuch as the employee provident fund and promote public-private partnerships.

Published: November 2016

Located in landslide prone areas, Cipanas and Pacet sub-districts are placed in areas where land uses are very dynamic. Land use change analysis is needed in these sub-districts for assessing its pattern and the driving factors that caused the change. Moreover, the results from the analysis can be used as input for land use change modeling to predict land use in the future for supporting landslide exposure assessment. ἀe objective of this research is to assess spatio temporal dynamic of landslide exposure by integrating land use change modeling using CLUE-S and landslide exposure assessment. ἀe obtained Kappa value was classiḀed as high agreement. Future land use prediction was conducted by considering three scenarios, baseline scenario (no restriction), scenario 1 (restriction in conservation area), and scenario 3 (restriction in conservation area and landslide prone area). Result of future land use prediction year 2031 in baseline scenario dominated by settlement and infrastructure expansion and forest conversion into another land use. However, implementation of scenario 1 and 2 in the model, were successfully restricts forest conversion and development of settle-ment and infrastructure in landslide prone area. Landslide exposure assessment was conducted by combining weighted asset map and landslide susceptibility map. ἀere were two type of asset considered in this research, social and physical asset. Population density was applied as a factor for social asset, while land use was applied as a factor for physical asset. Weight of assets and their factors was determined based on experts opinion by using Analytic Hierarchy Process (AHP) approach. ἀe result landslide exposure assessment shows that high and medium landslide exposure area follow pat-tern of settlement and infrastructure land use. Future landslide exposure assessment by considering baseline scenario resulted in the increasing of high landslide exposure area in year 2031. On the other hand, by applying restriction in scenario 1 and 2, high landslide exposure can be reduced.

Tujuan dalam penelitian ini adalah untuk mengetahui persepsi pemuda tentang keistimewaan Yogyakarta dan implikasinya bagi ketahanan politik Daerah Istimewaan Yogyakarta. Penelitian ini merupakan penelitian lapangan (field study research) dengan menggunakan metode penelitian diskriptif (descriptive research). Pengumpulan data menggunakan teknik observasi, wawancara mendalam, dan pengumpulan berbagai dokumentasi yang terkait dengan subjek maupun objek penelitian..Dampak dari persepsi pemuda terhadap status keistimewaan Yogyakarta bisa dilihat dengan program kerja Karang Taruna Kabupaten Bantul yang banyak melakukan berbagai kegiatan yang berkaitan dengan agenda keistimewan Yogyakarta. Pemuda yang duduk sebagai pengurus Karang Taruna Kabupaten Bantul mendukung, setuju dan siap melaksanakan penetapan Sri Sultan dan Pakualam sebagai gubernur. Dukungan lain yakni dilakukan dengan memasukkan agenda keistimewaan dalam program-program Karang Taruna Kabupaten Bantul seperti ikut mensosialisasikan UU serta peraturan turunan tentang keistimewaan kepada masyarakat luas. Perbedaan persepsi pemuda terihat jelas pada pandangan tentang suksesi kepemimpinan pasca Sri Sultan Hamengku Buwono X. Meskipun terjadi perbedaan persepsi tentang ketahanan politik wilayah di Daerah Istimewa Yogyakarta tetap relatif tangguh dengan adanya legitimasi dari rakyat Yogyakarta dan pemerintah pusat

There have been studied morphological safety and functional state of the explants of human placenta, umbilical cord and fetal membranes by vital staining techniques using the MTT and resazurin reduction tests, level of glucose in incubation medium, activity of lactate dehydrogenase and alkaline phosphatase before and after cryopreservation. It has been found that proposed program of cryopreservation allows keeping a high level of viability of the explants of placenta, umbilical cord and fetal membranes, the most informative methods of assessing the safety of these biological objects before and after cryopreservation are method of vital staining, determination of glucose content in incubation medium, MTT-test and resazurin reduction test.
CD4+ T-helpers in TCR-dependent tumor immunosurveillance and T-cell based adoptive transfer immunotherapy: are they really that helpful?
Authors: Plachynta M.
Published: November 2016

In this brief review the advances and hurdles of the modern-day ACT (adoptive cell transfer) immunotherapy of cancer are discussed, with the focus on the positive or negative role of CD4+ T helper lymphocytes as one of major constituents of oncologic patient-administered CIK (cytokine-induced killers) lymphocyte culture. The beneficial role of CD4+ T helpers in adoptively-transferred lymphocyte culture is considered, questioned and being put under doubt. “Infectious tolerance” and tumor “immune avoidance” phenomena are described, emphasizing on their dramatic implications for cancer ACT therapy. The ways to circumvent apparent undesired effects of CD4+ T helpers elevated presence in CIK bulk mass are discussed, such as complete removal of CD4 -positive cells, along with a less radical measure, which is depletion of CD4+CD25+FoxP3+ T regulatory lymphocytes from bulk CIK culture.

Neural stem cell niches in the adult mammalian brain
Authors: Tsupykov O.
Published: November 2016

Stem cells of the central nervous system have received a great deal of attention in neurobiology in the last decade.  It has been shown that neurogenesis occurs in the postnatal period in specialized niches of the adult mammalian brain. The niche is a key regulator of stem cell behavior. Recent data underscore the complexity and heterogeneity of the different components of the niche, and the presence of local signaling microdomain. The review is devoted to recent views on the structural organization of neurogenic niches and regulatory factors involved at different stages of neurogenesis in the postnatal period. Understanding of stem cells behavior in the niches can serve as a basis for determination of these cells function in the adult brain.
