    Full Text Available Abstract Background Enrichment testing assesses the overall evidence of differential expression behavior of the elements within a defined set. When we have measured many molecular aspects, e.g. gene expression, metabolites, proteins, it is desirable to assess their differential tendencies jointly across platforms using an integrated set enrichment test. In this work we explore the properties of several methods for performing a combined enrichment test using gene expression and metabolomics as the motivating platforms. Results Using two simulation models we explored the properties of several enrichment methods including two novel methods: the logistic regression 2-degree of freedom Wald test and the 2-dimensional permutation p-value for the sum-of-squared statistics test. In relation to their univariate counterparts we find that the joint tests can improve our ability to detect results that are marginal univariately. We also find that joint tests improve the ranking of associated pathways compared to their univariate counterparts. However, there is a risk of Type I error inflation with some methods and self-contained methods lose specificity when the sets are not representative of underlying association. Conclusions In this work we show that consideration of data from multiple platforms, in conjunction with summarization via a priori pathway information, leads to increased power in detection of genomic associations with phenotypes.

    Full Text Available ENERCA (the European Network for Rare and Congenital Anemias is a European Commission funded project since 2002. Rare anaemias in Europe comprise haemoglobin disorders, such as thalassemias or sickle cell disease, and other rarer disorders, including inherited diseases of the red cell membrane, of the red cell enzymes, as well as anaemias related to disorders of iron metabolism. Education and training on rare anaemias is one of the main objectives of ENERCA and several educational initiatives have been undertaken during the past and present phases of the project. Among these, the organisation of courses for health professionals, the provision of videos with prevention messages for patients and general practitioners were part of the previous phase, ENERCA 3. In the current phase of the ENERCA project, called e-ENERCA, the workpackage dedicated to Education and Training mainly focuses on training of young physicians, biologists or scientists in the field of diagnosis and management of rare anaemias. The specificity of e-ENERCA is to be based principally on new communication e-tool. Two main educational axes will be developed: the organisation of on-site courses including interactive sessions with voting boxes and the implementation of an online e-learning platform.

  11. Cross-platform learning: on the nature of children's learning from multiple media platforms.

    Science.gov (United States)

    Fisch, Shalom M

    2013-01-01

    It is increasingly common for an educational media project to span several media platforms (e.g., TV, Web, hands-on materials), assuming that the benefits of learning from multiple media extend beyond those gained from one medium alone. Yet research typically has investigated learning from a single medium in isolation. This paper reviews several recent studies to explore cross-platform learning (i.e., learning from combined use of multiple media platforms) and how such learning compares to learning from one medium. The paper discusses unique benefits of cross-platform learning, a theoretical mechanism to explain how these benefits might arise, and questions for future research in this emerging field.

    Full Text Available Security is an important issue in the actual educational context where e-learning increases in popularity and increasingly more people are taking online courses. The e-learning platforms are today production systems that need to be secured. To achieve a good level of security, there are many important elements that must be taken into account: authentication, access control, data integrity, content protection, etc. Information security can be obtained using methods such as cryptography and network protocols. In this paper we will highlight some key security issues that must be taken into consideration in developing and using an e-learning platform. We will also examine some security aspects of one of the most popular open-source e-learning systems: Moodle.

  13. On designing a pervasive mobile learning platform

    2010-12-01

    Full Text Available This article presents the features, design and architecture of the Myst pervasive game platform that has been applied in creating pervasive mobile learning games in various contexts such as science festivals and museums in Finland. Based on our experiences with the development, we draw a set of design principles for creating successfully a pervasive game platform that can be easily ported to various contexts. These principles advocate openness, flexibility, interaction models, connections to the outside world, and participatory design of the game content. In the evaluation part we present preliminary results of tests conducted in Finland at the SciFest 2008 festival in Joensuu and at the Museum of Technology in Helsinki. The results suggest that games built with the Myst platform are particularly suitable for children and young adults, and these games motivate players to interact with the environment and help to learn by discovering new things. The Myst platform has clearly potential for similar success in other environments due to easy portability and extensibility.

    This article provides a knowledge and understanding of an international, collaborative, cultural learning model for students from the United States and Scotland. Internationalizing the student experience has been instrumental for student learning for the past eight years. Both countries have developed programs that have enriched and enhanced the overall student learning experience, mainly through the sharing of evidence-based care in both hospital and community settings. Student learning is at the heart of this international model, and through practice learning, leadership, and reflective practice, student immersion in global health care and practice is immense. Moving forward, we are seeking new opportunities to explore learning partnerships to provide this collaborative cultural learning experience.

    Full Text Available Nowadays the role of educational platforms is more than obvious, thanks to websites and modern platforms like Microsoft SharePoint designed for e-learning. We consider that the next generation of learning platforms will be m-learning platforms. These kind of platforms offer first of all mobility for the potential users of PDAs, pocket PCs, smart phones and other modern mobile devices, discovered and developed in last years. One of the most important aspect of these manners of e-learning is the display mode. Classic systems like personal computers have a bigger screen, modern portable devices have a few inches screens and the problem is to adapt the structure of websites and platforms for pocket PC screens and in the same time to develop the capability to produce same experience and usefulness to all users.

  20. Geolinde - a geographical online learning platform

    Science.gov (United States)

    Steinmüller, Max

    2017-04-01

    Starting about ten years ago during a classroom project on Africa, two colleagues and me started developing an educational platform with geographic content: www.geolinde.musin.de The basic concept was to collect and present a wide range of free educational materials, which could be used by teachers, students and anyone who is interested in geography as well. Soon we found out that producing units for our students also means working on age-appropriate texts on each topic. We made our learning units matching the curriculum for Bavarian 'Gymnasium' and are still working on the improvement of each single unit, especially on the basis of suggestions by our students and our teaching experience. The main advantage in teaching with units from geolinde is that the students work at their own speed, repeat topics, use the glossary or have a look at the skill pages. Everyone uses the wide range of materials in his own way to achieve the curricular goals. Many topics contain short online tests, so that the students can control their basic understanding. The teacher is set free for giving helpful advice, discussing special questions and to monitor the learning progress. After a certain time a question and answer session follows and puts the focus on major curricular goals. Until now www.geolinde.musin.de consists of several blended learning units: Africa, Europe, Climate, Climate Change, Plate tectonics,… It also contains thematic pages on many geographical skills, a glossary of more than one thousand geographic terms and last but not least a collection of approximately 23.000 photos of places of interest all around the world. All the many thousand web pages can be used freely (CC-BY-SA 4.0). The only limitation is www.geolinde.musin.de is available in German only.

    Scientific software has become an indispensable commodity for the production, processing and analysis of empirical data but also for modelling and simulation of complex processes. Software has a significant influence on the quality of research results. For strengthening the recognition of the academic performance of scientific software development, for increasing its visibility and for promoting the reproducibility of research results, concepts for the publication of scientific software have to be developed, tested, evaluated, and then transferred into operations. For this, the publication and citability of scientific software have to fulfil scientific criteria by means of defined processes and the use of persistent identifiers, similar to data publications. The SciForge project is addressing these challenges. Based on interviews a blueprint for a scientific software publishing platform and a systematic implementation plan has been designed. In addition, the potential of journals, software repositories and persistent identifiers have been evaluated to improve the publication and dissemination of reusable software solutions. It is important that procedures for publishing software as well as methods and tools for software engineering are reflected in the architecture of the platform, in order to improve the quality of the software and the results of research. In addition, it is necessary to work continuously on improving specific conditions that promote the adoption and sustainable utilization of scientific software publications. Among others, this would include policies for the development and publication of scientific software in the institutions but also policies for establishing the necessary competencies and skills of scientists and IT personnel. To implement the concepts developed in SciForge a combined bottom-up / top-down approach is considered that will be implemented in parallel in different scientific domains, e.g. in earth sciences, climate research and

  16. "Mediman" - the smartphone as a learning platform?

    Science.gov (United States)

    Boeder, Niklas

    2013-01-01

    Mobile devices with a connection to the internet - smartphones - are seen all over the place since the popular introduction of the Apple iPhone. Similar products existed but no company managed to combine simplicity and functionality so seamlesly. Their market share increases constantly and web sites get optimised for the small display sizes (often referred to as "responsive webdesign") otherwise the usability lacks. Students seem to like smartphones aswell and a good question is if and to what extend those devices can play a role in e-learning. "Mediman", an adaptation of the common game Hangman has been developed for smartphones. Test users asked to complete an online questionnaire. So far, only few e-learning applications for smartphones seem to exist. This is reflected in the low usage frequency. Especially the fact that most of the test users wear a smartphone with them all the time makes it an ideal learning plattform. Short learning sessions were rated more important than continuous text. The majority of the 11 test users rated Mediman as well developed. The foremost question whether a smartphone e-learning application is feasible must be answered positive - acceptance in the test user group was shown. E-learning applications on smartphones will be an important topic in the future as market shares increase constantly. Further studies are required due to the small number of partitipants in our survey.

We will also look forward to the options likely to change e-learning in the near future and improve physician performance and patient outcomes.

  18. Environmental enrichment protects spatial learning and hippocampal neurons from the long-lasting effects of protein malnutrition early in life.

    Soares, Roberto O; Horiquini-Barbosa, Everton; Almeida, Sebastião S; Lachat, João-José

    2017-09-29

    As early protein malnutrition has a critically long-lasting impact on the hippocampal formation and its role in learning and memory, and environmental enrichment has demonstrated great success in ameliorating functional deficits, here we ask whether exposure to an enriched environment could be employed to prevent spatial memory impairment and neuroanatomical changes in the hippocampus of adult rats maintained on a protein deficient diet during brain development (P0-P35). To elucidate the protective effects of environmental enrichment, we used the Morris water task and neuroanatomical analysis to determine whether changes in spatial memory and number and size of CA1 neurons differed significantly among groups. Protein malnutrition and environmental enrichment during brain development had significant effects on the spatial memory and hippocampal anatomy of adult rats. Malnourished but non-enriched rats (MN) required more time to find the hidden platform than well-nourished but non-enriched rats (WN). Malnourished but enriched rats (ME) performed better than the MN and similarly to the WN rats. There was no difference between well-nourished but non-enriched and enriched rats (WE). Anatomically, fewer CA1 neurons were found in the hippocampus of MN rats than in those of WN rats. However, it was also observed that ME and WN rats retained a similar number of neurons. These results suggest that environmental enrichment during brain development alters cognitive task performance and hippocampal neuroanatomy in a manner that is neuroprotective against malnutrition-induced brain injury. These results could have significant implications for malnourished infants expected to be at risk of disturbed brain development. Copyright © 2017 Elsevier B.V. All rights reserved.

    The Geminiviridae family encompasses a group of single-stranded DNA viruses with twinned and quasi-isometric virions, which infect a wide range of dicotyledonous and monocotyledonous plants and are responsible for significant economic losses worldwide. Geminiviruses are divided into nine genera, according to their insect vector, host range, genome organization, and phylogeny reconstruction. Using rolling-circle amplification approaches along with high-throughput sequencing technologies, thousands of full-length geminivirus and satellite genome sequences were amplified and have become available in public databases. As a consequence, many important challenges have emerged, namely, how to classify, store, and analyze massive datasets as well as how to extract information or new knowledge. Data mining approaches, mainly supported by machine learning (ML) techniques, are a natural means for high-throughput data analysis in the context of genomics, transcriptomics, proteomics, and metabolomics. Here, we describe the development of a data warehouse enriched with ML approaches, designated geminivirus.org. We implemented search modules, bioinformatics tools, and ML methods to retrieve high precision information, demarcate species, and create classifiers for genera and open reading frames (ORFs) of geminivirus genomes. The use of data mining techniques such as ETL (Extract, Transform, Load) to feed our database, as well as algorithms based on machine learning for knowledge extraction, allowed us to obtain a database with quality data and suitable tools for bioinformatics analysis. The Geminivirus Data Warehouse (geminivirus.org) offers a simple and user-friendly environment for information retrieval and knowledge discovery related to geminiviruses.

    Full Text Available It is substantially accepted that constructivism proposes knowledge as “not a fixed object”; constructed by an individual through her own experiences. As a learning theory, constructivism in education emphasizes collaborative learning, such as authentic challenging projects involving in students, teachers and experts in the learning community. Its goal is to create learning communities that are more closely related to the collaborative practice of the real world as strongly reflected in social constructivist idea. The technologies used in the filed of education will support learning through collaborative practices, using learners’ experiences for “meaning making”. The challenge now is to extend the educational networks so that it offers access to learning resources, online storage and tools for communication and management not just within the limitation of school and time. Through learning platforms, such as Moodle, teachers and administrators may bring hardware, software and supporting services together to enable more effective conditions among teachers and students. In this study, Moodle was used to support the 4th grade pre-service language teachers’ (student teachers one of the academic courses, named as “Field Experience”. The student teachers were expected to prepare graduation theses in the field of English language teaching. Moodle was integrated as a technological learning aid and used as online support throughout a semester course. So, we will discuss how Moodle was integrated as a learning platform, while discussing, the use of Moodle as a “course supporter” process, steps and the sample activities will be presented as well.

    Protein post-translational modifications (PTMs) have increasingly become a research field of incredible importance to fully understand the regulation of biological processes in health and disease. Among PTMs, glycosylation is one of the most studied for which contributed the development and improvement of enrichment techniques. Nowadays, glycoprotein enrichment methods are based on lectin affinity, covalent interactions, and hydrophilic interaction liquid chromatography (HILIC). Nonetheless, the nanotechnology era has fetched new methods to enrich glycoproteins from complex samples as human biological fluids. For instance, magnetic nanoparticles (MNPs) are being used as an interesting enrichment approach allowing a better characterization of glycoproteins and glycopeptides.In this chapter, we describe an enrichment method based on MNPs functionalized with lectins (Concavalin A, wheat germ agglutinin, and Maackia amurensis lectin) to enrich specific sets of glycoproteins from biological fluids. Moreover, it is proposed a bioinformatic strategy to deal with data retrieved from mass spectrometry analysis of enriched samples aiming the identification of relevant biological processes modulated by a given stimuli and, ultimately, of new biomarkers for disease screening/management.

    Full Text Available ABSTRACT The rate of technological diffusion and the pace at which technology is altering how and with whom we connect is astounding. Although not at the same pace, theoretical views of learning and teaching are also changing. Whereas much of the initial e-learning simply patterned old models of teaching and learning, the new technological possibilities and realities encourage us to think differently about what is meant by education (Brown, 2000. In this paper, we provide a stepping stone in some of the theoretical background, history, and possibilities for learning systems and platforms in the Web 2.0 era. We share a case study that reflects the experiences of a small university that is moving towards E-Learning 2.0 while simultaneously increasing interoperability by using e-learning standards reflected in the widely-used reference model called SCORM (Sharable Content Object Reference Model. We also highlight the strengths and weaknesses of SCORM in allowing for learning management systems to have a Web 2.0 character.

    The paper describes the development of a new service within the collaboration platform "Online Communities", entirely designed and implemented by our working group at the University of Trento. The system is able to track the activities performed by each participant of a learning community. The service, called "workbook", represents the first of a series of innovations that we will introduce in the system to improve the collaboration level between its participants. The metaphor of virtual communities, in fact, allows us to develop and expand the services' scenarios. Even the workbook service itself benefits of this community approach.

  12. Comparison of three targeted enrichment strategies on the SOLiD sequencing platform.

    Directory of Open Access Journals (Sweden)

    Dale J Hedges

    Full Text Available Despite the ever-increasing throughput and steadily decreasing cost of next generation sequencing (NGS, whole genome sequencing of humans is still not a viable option for the majority of genetics laboratories. This is particularly true in the case of complex disease studies, where large sample sets are often required to achieve adequate statistical power. To fully leverage the potential of NGS technology on large sample sets, several methods have been developed to selectively enrich for regions of interest. Enrichment reduces both monetary and computational costs compared to whole genome sequencing, while allowing researchers to take advantage of NGS throughput. Several targeted enrichment approaches are currently available, including molecular inversion probe ligation sequencing (MIPS, oligonucleotide hybridization based approaches, and PCR-based strategies. To assess how these methods performed when used in conjunction with the ABI SOLID3+, we investigated three enrichment techniques: Nimblegen oligonucleotide hybridization array-based capture; Agilent SureSelect oligonucleotide hybridization solution-based capture; and Raindance Technologies' multiplexed PCR-based approach. Target regions were selected from exons and evolutionarily conserved areas throughout the human genome. Probe and primer pair design was carried out for all three methods using their respective informatics pipelines. In all, approximately 0.8 Mb of target space was identical for all 3 methods. SOLiD sequencing results were analyzed for several metrics, including consistency of coverage depth across samples, on-target versus off-target efficiency, allelic bias, and genotype concordance with array-based genotyping data. Agilent SureSelect exhibited superior on-target efficiency and correlation of read depths across samples. Nimblegen performance was similar at read depths at 20× and below. Both Raindance and Nimblegen SeqCap exhibited tighter distributions of read depth

    Full Text Available Trust level concept is a topic that has opened a knowledge area about the profile evaluation and the people participation in Social Networks. These have presented a high knowledge profit, but at the same time it is necessary to analyze a group of variables to determine the trust participants’ degree.In addition, this is a topic that from some years ago has been presenting a big expectation to settle some alternatives to generate confidence in an activer community on internet. To establish these parameters it is important to define a model to abstract some variables that are involved in this process. For this, it is relevant to take into account the semantic languages as one of the alternatives that allow these kinds of activities. The purpose of this article is to analyze the Trust Levels definition in the contents that are shared on Open Source Virtual learning Platforms through the use of a model of representation of semantic languages. The last ones allow determining the trust in the use of learning objects that are shared in this kind of platforms

  14. Service-learning and learning communities: two innovative school projects that are mutually enriched

    Directory of Open Access Journals (Sweden)

    Carmen ÁLVAREZ ÁLVAREZ

    2015-12-01

    Full Text Available This article reflects on the interrelationships that exist between two educational projects of today: service-learning (ApS and learning communities (CdA. The ApS is an educational methodology applied worldwide where a single project combines a learning based on experience with the implementation of a service to the community. CdA is a school transformation project to achieve that the information society does not exclude any person, constituting a reality in more than one hundred and ninety schools in Spain and Latin America. Between the two, it is possible to show differences, especially in what refers to its theoretical substrates, but in actual teaching practice in schools there is some harmony, particularly in the so closely that they cultivate both projects with the school community. Therefore, we conclude that service-learning and learning communities can occur as two innovative and relevant today projects which can be mutually enriching: because for both the approach school-community-environment and volunteering is essential.

    2015-06-01

    Full Text Available Chlamydia trachomatis is an important human pathogen that replicates inside the infected host cell in a unique vacuole, the inclusion. The formation of this intracellular bacterial niche is essential for productive Chlamydia infections. Despite its importance for Chlamydia biology, a holistic view on the protein composition of the inclusion, including its membrane, is currently missing. Here we describe the host cell-derived proteome of isolated C. trachomatis inclusions by quantitative proteomics. Computational analysis indicated that the inclusion is a complex intracellular trafficking platform that interacts with host cells' antero- and retrograde trafficking pathways. Furthermore, the inclusion is highly enriched for sorting nexins of the SNX-BAR retromer, a complex essential for retrograde trafficking. Functional studies showed that in particular, SNX5 controls the C. trachomatis infection and that retrograde trafficking is essential for infectious progeny formation. In summary, these findings suggest that C. trachomatis hijacks retrograde pathways for effective infection.

  1. Moodle 2.0: Shifting from a Learning Toolkit to a Open Learning Platform

    Science.gov (United States)

    Alier, Marc; Casañ, María José; Piguillem, Jordi

    Learning Management Systems (LMS) have reached a plateau of maturity in features, application to teaching practices and wide adoption by learning institutions. But the Web 2.0 carries new kinds of tools, services and ways of using the web; personally and socially. Some educators and learners have started to advocate for a new approach to frame one's learning sources, from the LMS course space towards Personal Learning Environments (PLE). But PLE's are characterized by its absence of structure, just what is provided by open standards and mashup techniques. Based on 5 years of participative observation research, this article explains the changes in architecture performed on the second version of Moodle, why did these changes happen and what should be the next steps so Moodle can shift from being a learning tool to a true open learning platform.

  2. Evaluating the E-Learning Platform from the Perspective of Knowledge Management: The AHP Approach

    Directory of Open Access Journals (Sweden)

    I-Chin Wu

    2013-06-01

    Full Text Available A growing number of higher education institutions have adopted asynchronous and synchronous Web-based learning platforms to improve students’ learning efficiency and increase learning satisfaction in the past decade. Unlike traditional face-to-face learning methods, e-learning platforms allow teachers to communicate with students and discuss course content anytime or anywhere. In addition, the teaching material can be reused via the e-learning platforms. To understand how students use e-learning platforms and what the implications are, we conducted an empirical study of the iCAN e-learning platform, which has been widely used in Fu-Jen Catholic University since 2005. We use the Analytic Hierarchy Process (AHP, a well-known multi-criteria evaluation approach, to compare five practices, i.e. the functions of the iCAN teaching platform. We adopted a brainstorming approach to design a questionnaire to measure learners’ perception of the e-learning platform based on the theory of knowledge transforming process in knowledge management. Accordingly, the model considers functioning and objectivity in terms of the following three attributes of learning effectiveness: individual learning, group sharing and learning performance. Twelve criteria with twelve evaluation items were used to investigate the effectiveness of the five practices. We also evaluated the strengths and weaknesses of the functions based on the types of courses in the iCan platform. We expect that the empirical evaluation results will provide teachers with suggestions and guidelines for using the e-learning platform effectively to facilitate their teaching activities and promote students’ learning efficiency and satisfaction.

  5. An integrated on-chip platform for negative enrichment of tumour cells.

    2016-08-15

    The study of cancer cells in blood, popularly called circulating tumour cells (CTCs), has exceptional prospects for cancer risk assessment and analysis. Separation and enrichment of CTCs by size-based methods suffer from a well-known recovery/purity trade-off while methods targeting certain specific surface proteins can lead to risk of losing CTCs due to Epithelial to Mesenchymal Transition (EMT) and thus adversely affect the separation efficiency. A negative selection approach is thus preferred for tumour cell isolation as it does not depend on biomarker expression or defines their physical property as the separation criteria. In this work, we developed a microfluidic chip to isolate CTCs from whole blood samples without targeting any tumour specific antigen. This chip employs a two-stage cell separation: firstly, magnetophoresis depletes the white blood cells (WBCs) from a whole blood sample and is then followed by a micro-slit membrane that enables depleting the red blood cells (RBCs) and retaining only the tumour cells. By creating strong magnetic field gradients along with customized antibody complexes to target WBCs, we are able to remove >99.9% of WBCs from 1:1 diluted blood at a sample processing rate of 500μL/min. This approach achieves an average of >80% recovery of spiked tumour cells from 2mL of whole blood in a total assay processing time of 50min without multiple processing steps.

  11. Quantification of histone modification ChIP-seq enrichment for data mining and machine learning applications

    Directory of Open Access Journals (Sweden)

    Bekiranov Stefan

    2011-08-01

    Full Text Available Abstract Background The advent of ChIP-seq technology has made the investigation of epigenetic regulatory networks a computationally tractable problem. Several groups have applied statistical computing methods to ChIP-seq datasets to gain insight into the epigenetic regulation of transcription. However, methods for estimating enrichment levels in ChIP-seq data for these computational studies are understudied and variable. Since the conclusions drawn from these data mining and machine learning applications strongly depend on the enrichment level inputs, a comparison of estimation methods with respect to the performance of statistical models should be made. Results Various methods were used to estimate the gene-wise ChIP-seq enrichment levels for 20 histone methylations and the histone variant H2A.Z. The Multivariate Adaptive Regression Splines (MARS algorithm was applied for each estimation method using the estimation of enrichment levels as predictors and gene expression levels as responses. The methods used to estimate enrichment levels included tag counting and model-based methods that were applied to whole genes and specific gene regions. These methods were also applied to various sizes of estimation windows. The MARS model performance was assessed with the Generalized Cross-Validation Score (GCV. We determined that model-based methods of enrichment estimation that spatially weight enrichment based on average patterns provided an improvement over tag counting methods. Also, methods that included information across the entire gene body provided improvement over methods that focus on a specific sub-region of the gene (e.g., the 5' or 3' region. Conclusion The performance of data mining and machine learning methods when applied to histone modification ChIP-seq data can be improved by using data across the entire gene body, and incorporating the spatial distribution of enrichment. Refinement of enrichment estimation ultimately improved accuracy

They are seen as a complementary tool to support learning or, as in many cases, as the primary tool to do it (possibly the only one. In traditional learning, teachers can easily get an insight into how their students work and learn, and how they interact in the classroom. However, in online learning, it is more difficult for teachers to see how individual students behave. Affective states and learning styles are determinant in students’ performance. Together with stress, these are crucial factor to success. It is believed that the sole use of an E-learning platform can in itself be a cause of stress for students. Estimating, in a non-invasive way, such parameters, and taking measures to deal with them, are then the goal of this paper. We do not consider the use of dedicated sensors (invasive such as special gloves or wrist bracelets since we intend not to be dependent on specific hardware and also because we believe that such specific hardware can induce for itself some alteration in the parameters being analysed. Our work focuses on the development of a new module (Dynamic Recognition Module to incorporate in Moodle E-learning platform, to accommodate individualized support to E-learning students.

They are seen as a complementary tool to support learning or, as in many cases, as the primary tool to do it (possibly the only one. In traditional learning, teachers can easily get an insight into how their students work and learn, and how they interact in the classroom. However, in online learning, it is more difficult for teachers to see how individual students behave. Affective states and learning styles are determinant in students’ performance. Together with stress, these are crucial factor to success. It is believed that the sole use of an E-learning platform can in itself be a cause of stress for students. Estimating, in a non-invasive way, such parameters, and taking measures to deal with them, are then the goal of this paper. We do not consider the use of dedicated sensors (invasive such as special gloves or wrist bracelets since we intend not to be dependent on specific hardware and also because we believe that such specific hardware can induce for itself some alteration in the parameters being analysed. Our work focuses on the development of a new module (Dynamic Recognition Module to incorporate in Moodle E-learning platform, to accommodate individualized support to E-learning students.

    Full Text Available In education the linguistic is the mode most commonly assessed because it is important for students to write clear, complex pieces to show their understanding of content. However, in worlds outside of classrooms additional modes, such as visual, aural, and digital are often used to convey messages. This article demonstrates the value of multimodal learning (the use of more than one mode as a means for student expression, specifically in responding to young adult literature. Here, I share how students had rich interpretations of a text through the use multiple modes.

    Full Text Available Background: Doctors’ verbal and non-verbal communication skills have an impact on patients’ health outcomes, so it is important for medical students to develop these skills. Traditional, non-verbal communication skills training can involve a tutor manually annotating a student's non-verbal behaviour during patient–doctor consultations, but this is very time-consuming. Tele-conference systems have been used in verbal communication skills training. Methods: We describe EQClinic, a system that enables verbal and non-verbal communication skills training during tele-consultations with simulated patients (SPs, with evaluation exercises promoting reflection. Students and SPs can have tele-consultations through the tele-consultation component. In this component, SPs can provide feedback to students through a thumbs-up/ thumbs-down tool and a comments box. EQClinic automatically analyses communication features in the recorded consultations, such as facial expressions, and provides graphical representations. Our 2015 pilot study investigated whether EQClinic helped students be aware of their non-verbal behaviour and improve their communication skills, and evaluated the usability of the platform. Students received automated feedback, and SP and tutor evaluations, and then completed self-assessment and reflection questionnaires. Results: Eight medical students and three SPs conducted 13 tele-consultations using EQClinic. More students paid attention to their non-verbal communication and students who were engaged in two consultations felt more confident in their second consultation. Students rated the system positively, felt comfortable using it (5.9/7, and reported that the structure (5.4/7 and information (5.8/7 were clear.

    2016-01-01

    Hybrid texts such as Horizons: Exploring the Universe, Hybrid (with CengageNOW) and Universe, Hybrid (with CengageNOW) are designed for higher education learning of astronomy in undergraduate online courses. In these hybrid texts, quiz and test bank questions have been revised to minimize easy look-up of answers by students via the Internet and discussion threads have been re-designed to allow for student selection of learning and for personalized learning, for example. By establishing connections between the student and the course content, student learning is enriched, students spend more time learning the material, student copying of answers is minimized, and student social engagement on the subject matter is increased. In this presentation, we discuss how Hybrid texts in Astronomy can increase student learning in online courses.

    Full Text Available Background and aims. The infusion of enriched CMV-specific donor T-cells appears to be a suitable alternative for the treatment of drug resistant CMV reactivation or de novo infection after both solid organ and hematopoietic stem cell transplantation. Antiviral lymphocytes can be selected from apheresis products using the CliniMACS Cytokine-Capture-System® either with the well-established CliniMACS® Plus (Plus device or with its more versatile successor CliniMACS Prodigy® (Prodigy. Methods. Manufacturing of CMV-specific T-cells was carried out with the Prodigy and Plus in parallel starting with 0.8-1*109 leukocytes collected by lymphapheresis (n=3 and using the MACS GMP PepTivator® HCMVpp65 for antigenic re-stimulation. Target and non-target cells were quantified by a newly developed single-platform assessment and gating strategy using positive (CD3/CD4/CD8/CD45/IFN-gamma, negative (CD14/CD19/CD56, and dead cell (7-AAD discriminators. Results. Both devices produced largely similar results for target cell viabilities: 37.2%-52.2% (Prodigy vs. 51.1%-62.1% (Plus CD45+/7-AAD- cells. Absolute numbers of isolated target cells were 0.1-3.8*106 viable IFN-gamma+ CD3+ cells. The corresponding proportions of IFN-gamma+ CD3+ cells ranged between 19.2% and 95.1% among total CD3+ cells and represented recoveries of 41.9%-87.6%. Within two parallel processes predominantly IFN-gamma+ CD3+CD8+ cytotoxic T-cells were enriched compared to one process that yielded a higher amount of IFN-gamma+ CD3+CD4+ helper T lymphocytes. T-cell purity was higher for the Prodigies products that displayed a lower content of contaminating IFN-gamma- T-cells (3.6%-20.8% compared to the Plus products (19.9%-80.0%. Conclusions. The manufacturing process on the Prodigy saved both process and hands-on time due to its higher process integration and ability for unattended operation. Although the usage of both instruments yielded comparable results, the lower content of residual IFN

    Online learning (or eLearning) is in constant evolution in medicine. An analytical survey of the websites of eight academic societies and medical schools was carried out. These sites were evaluated against parameters that define the quality of an eLearning website, as well as the shareable content object reference model (SCORM) technical standards. All studied platforms were maintained by a webmaster and regularly updated. Only two platforms had teleconference opportunities, five had courses in PDF format, and four allowed online testing. Based on SCORM standards, only four platforms allowed direct access without a password. The content of all platforms was adaptable, interoperable and reusable. But their sustainability was difficult to assess. In parallel, we developed the first eLearning platform to be used as part of a university diploma in microsurgery in France. The platform was evaluated by students enrolled this diploma program. A satisfaction survey and platform evaluation showed that students were generally satisfied and had used the platform for microsurgery education, especially the seven students living abroad. ELearning for microsurgery allows the content to be continuously updated, makes for fewer classroom visits, provides easy remote access, and especially better training time management and cost savings in terms of travel and accommodations.

    Full Text Available Open Source (OS community offers numerous eLearning platforms of both types: Learning Management Systems (LMS and Learning Content Systems (LCS. General purpose OS intermediaries such as SourceForge, ObjectWeb, Apache or specialized intermediaries like CampusSource reduce the cost to locate such eLearning platforms. Still, it is impossible to directly compare the functionalities of those OS software products without performing detailed testing on each product. Some articles available from eLearning Wikipedia show comparisons between eLearning platforms which can help, but at the end they barely serve as documentation which are becoming out of date quickly (1. The absence of integration activities between OS eLearning platforms - which are sometimes quite similar in terms of functionalities and implementation technologies - is sometimes critical since most of the OS projects possess small financial and human resources. This paper shows a possible solution for these barriers of OS eLearning platforms. We propose the Model Driven Architecture (MDA concept to capture functionalities and to identify similarities between available OS eLearning platforms. This contribution evolved from a fruitful discussion at the 2nd CampusSource Developer Conference at the University of Muenster (27th August 2004.Die Open Source-Community bietet zahlreiche eLearning-Plattformen an: Learning Management-Systeme (LMS sowie Learning Content-Systeme (LCS.

    Severe mental illness (SMI), including schizophrenia, bipolar disorder and severe depression, is responsible for a substantial proportion of disability in the population. This article describes the aims and design of a research study that takes a novel approach to targeted prevention of SMI. It is based on the rationale that early developmental antecedents to SMI are likely to be more malleable than fully developed mood or psychotic disorders and that low-risk interventions targeting antecedents may reduce the risk of SMI. Families Overcoming Risks and Building Opportunities for Well-being (FORBOW) is an accelerated cohort study that includes a large proportion of offspring of parents with SMI and embeds intervention trials in a cohort multiple randomized controlled trial (cmRCT) design. Antecedents are conditions of the individual that are distressing but not severely impairing, predict SMI with moderate-to-large effect sizes and precede the onset of SMI by at least several years. FORBOW focuses on the following antecedents: affective lability, anxiety, psychotic-like experiences, basic symptoms, sleep problems, somatic symptoms, cannabis use and cognitive delay. Enrolment of offspring over a broad age range (0 to 21 years) will allow researchers to draw conclusions on a longer developmental period from a study of shorter duration. Annual assessments cover a full range of psychopathology, cognitive abilities, eligibility criteria for interventions and outcomes. Pre-emptive early interventions (PEI) will include skill training for parents of younger children and courses in emotional well-being skills based on cognitive behavioural therapy for older children and youth. A sample enriched for familial risk of SMI will enhance statistical power for testing the efficacy of PEI. FORBOW offers a platform for efficient and unbiased testing of interventions selected according to best available evidence. Since few differences exist between familial and 'sporadic' SMI, the

    2009-12-01

    Full Text Available While our multimedia world, with rapid advances in technologies, now challenges educators to consider new pedagogies that expand cultural and linguistic diversity, the potential for information and communication technologies (ICT to support literacy learning in the early years remains a seriously under-researched area. There is an urgency to address a range of questions raised by teacher practitioners such as what new literacies will look like in their programs, how ICT can be used to learn in new ways, and which pedagogies of multiliteracies are relevant for early childhood education. This paper explores these questions in relation to knowledge management initiatives and e-learning opportunities. The Willy Wagtail Tale presents a case study of how knowledge management and e-learning is socially constructed to enrich multiliteracies experiences in the early years. The study occurred in a small Western Australian school committed to the Reggio Emilia teaching approach. Implications for educational research are that multiliteracies experiences occur inadvertently through children’s play, are integral to The Hundred Languages of Children, and are dramatically enriched through social constructivist knowledge management and child-centered e-learning.

    Margherita, Alessandro; Taurino, Cesare; Del Vecchio, Pasquale

    As a field at the intersection between computer science and people behavior, social computing can contribute significantly in the endeavor of innovating how individuals and groups interact for learning and working purposes. In particular, the generation of Internet applications tagged as web 2.0 provides an opportunity to create new “environments” where people can exchange knowledge and experience, create new knowledge and learn together. This chapter illustrates the design and application of a prototypal platform which embeds tools such as blog, wiki, folksonomy and RSS in a unique web-based system. This platform has been developed to support a case-based and project-driven learning strategy for the development of business and technology management competencies in undergraduate and graduate education programs. A set of illustrative scenarios are described to show how a learning community can be promoted, created, and sustained through the technological platform.

    Full Text Available Digital learning contents mainly come from materials designed by instructors, free network, commercial databases, digital libraries and digital archives. Our national digital archive projects started at 1999 and, since then, have produced many valuable digital resources. These resources will support many aspects of researches, teachings and learning. In addition, our government also launched a national e-learning project at 2002. Many sub-projects concerning contents and standards have been proceeding. But how digital learning contents are related to digital archive contents? This paper studies the relations between digital archive contents and digital learning contents from the viewpoints of metadata and digital objects processing. We find it is necessary to integrate the archive contents management system and learning contents management system. We also develop an integration system, called X-system and explain its design idea and system architecture.[Article content in Chinese

    The research and development of educational games, and the study of the educational value of interactive games in general, have lagged far behind efforts for games created for the purpose of entertainment. But evidence suggests that digital simulations and games have the "potential to advance multiple science learning goals, including motivation to learn science, conceptual understanding, science process skills, understanding of the nature of science, scientific discourse and argumentation, and identification with science and science learning." (NRC, 2011). It is also generally recognized that interactive digital games have the potential to promote the development of valuable learning and life skills, including data processing, decision-making, critical thinking, planning, communication and collaboration (Kirriemuir and MacFarlane, 2006). Video games are now played in 67% of American households (ESA, 2010), and across a broad range of ages, making them a potentially valuable tool for Science, Technology, Engineering and Mathematics (STEM) learning among the diverse audiences associated with informal science education institutions (ISEIs; e.g., aquariums, museums, science centers). We are attempting to capitalize on this potential by developing games based on the popular Microsoft Xbox360 gaming platform and the free Microsoft XNA game development kit. The games, collectively known as Deep-sea Extreme Environment Pilot (D.E.E.P.), engage ISEI visitors in the exploration and understanding of the otherwise remote deep-sea environment. Players assume the role of piloting a remotely-operated vehicle (ROV) to explore ocean observing systems and hydrothermal vent environments, and are challenged to complete science-based objectives in order to earn points under timed conditions. The current games are intended to be relatively brief visitor experiences (on the order of several minutes) that support complementary exhibits and programming, and promote interactive visitor

    Full Text Available Case-Based Learning (CBL has become an effective pedagogy for student-centered learning in medical education, which is founded on persistent patient cases. Flippped learning and Internet of Things (IoTs concepts have gained significant attention in recent years. Using these concepts in conjunction with CBL can improve learning ability by providing real evolutionary medical cases. It also enables students to build confidence in their decision making, and efficiently enhances teamwork in the learing environment. We propose an IoT-based Flip Learning Platform, called IoTFLiP, where an IoT infrastructure is exploited to support flipped case-based learning in a cloud environment with state of the art security and privacy measures for personalized medical data. It also provides support for application delivery in private, public, and hybrid approaches. The proposed platform is an extension of our Interactive Case-Based Flipped Learning Tool (ICBFLT, which has been developed based on current CBL practices. ICBFLT formulates summaries of CBL cases through synergy between students' and medical expert knowledge. The low cost and reduced size of sensor device, support of IoTs, and recent flipped learning advancements can enhance medical students' academic and practical experiences. In order to demonstrate a working scenario for the proposed IoTFLiP platform, real-time data from IoTs gadgets is collected to generate a real-world case for a medical student using ICBFLT.

    Objective: An emerging field of research indicates that physical activity can benefit cognitive functions and academic achievements in children. However, less is known about how academic achievements can benefit from specific types of motor activities (e.g., fine and gross) integrated into learning activities. Thus, the aim of this study was to investigate whether fine or gross motor activity integrated into math lessons (i.e., motor-enrichment) could improve children's mathematical performance. Methods: A 6-week within school cluster-randomized intervention study investigated the effects of motor-enriched mathematical teaching in Danish preadolescent children (n = 165, age = 7.5 ± 0.02 years). Three groups were included: a control group (CON), which received non-motor enriched conventional mathematical teaching, a fine motor math group (FMM) and a gross motor math group (GMM), which received mathematical teaching enriched with fine and gross motor activity, respectively. The children were tested before (T0), immediately after (T1) and 8 weeks after the intervention (T2). A standardized mathematical test (50 tasks) was used to evaluate mathematical performance. Furthermore, it was investigated whether motor-enriched math was accompanied by different effects in low and normal math performers. Additionally, the study investigated the potential contribution of cognitive functions and motor skills on mathematical performance. Results: All groups improved their mathematical performance from T0 to T1. However, from T0 to T1, the improvement was significantly greater in GMM compared to FMM (1.87 ± 0.71 correct answers) (p = 0.02). At T2 no significant differences in mathematical performance were observed. A subgroup analysis revealed that normal math-performers benefitted from GMM compared to both CON 1.78 ± 0.73 correct answers (p = 0.04) and FMM 2.14 ± 0.72 correct answers (p = 0.008). These effects were not observed in low math-performers. The effects were partly

    Health informatics has a major role to play in optimising the management and use of data, information and knowledge in health systems. As health systems undergo digital transformation, it is important to consider informatics approaches not only to curriculum content but also to the design of learning environments and learning activities for health professional learning and development. An example of such an informatics approach is the use of large-scale, integrated public health platforms on the Internet as part of health professional learning and development. This article describes selected examples of such platforms, with a focus on how they may influence the direction of health professional learning and development. Significance for public healthThe landscape of healthcare systems, public health systems, health research systems and professional education systems is fragmented, with many gaps and silos. More sophistication in the management of health data, information, and knowledge, based on public health informatics expertise, is needed to tackle key issues of prevention, promotion and policy-making. Platform technologies represent an emerging large-scale, highly integrated informatics approach to public health, combining the technologies of Internet, the web, the cloud, social technologies, remote sensing and/or mobile apps into an online infrastructure that can allow more synergies in work within and across these systems. Health professional curricula need updating so that the health workforce has a deep and critical understanding of the way that platform technologies are becoming the foundation of the health sector.

    Full Text Available with rapid development and increase in the amount of available resources in E-learning platforms, the need to design new architecture for such systems has become inevitable to improve the search quality and simplifying ways to take online courses. The integration of multi-agent systems has played a very important role in developing open, interactive and distributed learning systems. A lot of research in E-learning and multi-agent system have been put into developing infrastructure and providing content, security and trust issues have hardly ever been considered worth knowing that security issues may endanger the success of these platforms. The application of a control access policy, as one of the most important aspects of security, in E-learning platform based on multi agent systems , plays an important role to secure interaction with agents/users and reinforcing it with the integration of trust level .The work of this paper is to encode a new access control model developed in previous works based on ‘’ role based access control model ‘’ and trust level, on ‘’Organization based access control model’’ to improve the security level in E-learning platforms based on multi-agent systems. The encoded model is implemented and evaluated by “MotOrbac” tool, in order to define its validity context and limitations for a large and extended deployment.

We hope to let players perform efficient self learning for sports skills, indirectly foster mutual help, cooperation, nice norms of law-abiding via the learning of exercise rules, and become skilled at accurate recreation knowledge and first-aid expertise. Moreover, coaches can use the system as a teaching facility to mitigate loading on teaching.

  20. Mice in an enriched environment learn more flexibly because of adult hippocampal neurogenesis.

    2016-02-01

    We here show that living in a stimulus-rich environment (ENR) improves water maze learning with respect to specific key indicators that in previous loss-of-function experiments have been shown to rely on adult hippocampal neurogenesis. Analyzing the strategies employed by mice to locate the hidden platform in the water maze revealed that ENR facilitated task acquisition by increasing the probability to use effective search strategies. ENR also enhanced the animals' behavioral flexibility, when the escape platform was moved to a new location. Treatment with temozolomide, which is known to reduce adult neurogenesis, abolished the effects of ENR on both acquisition and flexibility, while leaving other aspects of water maze learning untouched. These characteristic effects and interdependencies were not seen in parallel experiments with voluntary wheel running (RUN), a second pro-neurogenic behavioral stimulus. Since the histological assessment of adult neurogenesis is by necessity an end-point measure, the levels of neurogenesis over the course of the experiment can only be inferred and the present study focused on behavioral parameters as analytical endpoints. Although the correlation of physical activity with precursor cell proliferation and of learning and the survival of new neurons is well established, how the specific functional effects described here relate to dynamic changes in the stem cell niche remains to be addressed. Nevertheless, our findings support the hypothesis that adult neurogenesis is a critical mechanism underlying the beneficial effects of leading an active live, rich in experiences.

    The use of virtual environments in science education has been constrained by the difficulty of guiding a learner's actions within the those environments. In this work, we demonstrate how advances in education software technology allow educators to create interactive learning experiences that respond and adapt intelligently to learner input within the virtual environment. This innovative technology provides a far greater capacity for delivering authentic inquiry-driven educational experiences in unique settings from around the world. Our immersive virtual field trips (iVFT) bring students virtually to geologically significant but inaccessible environments, where they learn through authentic practices of scientific inquiry. In one recent example, students explore the fossil beds in Nilpena, South Australia to learn about the Ediacaran fauna. Students interactively engage in 360° recreations of the environment, uncover the nature of the historical ecosystem by identifying fossils with a dichotomous key, explore actual fossil beds in high resolution imagery, and reconstruct what an ecosystem might have looked like millions of years ago in an interactive simulation. With the new capacity to connect actions within the iVFT to an intelligent tutoring system, these learning experiences can be tracked, guided, and tailored individually to the immediate actions of the student. This new capacity also has great potential for learning designers to take a data-driven approach to lesson improvement and for education researchers to study learning in virtual environments. Thus, we expect iVFT will be fertile ground for novel research. Such iVFT are currently in use in several introductory classes offered online at Arizona State University in anthropology, introductory biology, and astrobiology, reaching thousands of students to date. Drawing from these experiences, we are designing a curriculum for historical geology that will be built around iVFT-based exploration of Earth

    : In response to technological advances and growing dispersion of surgical practice around the globe, social media platforms have emerged in recent years as channels for surgeons to share experiences, ask questions, and learn from one another. To better understand surgeons' engagement with these platforms, we analyzed data from a closed-membership Facebook group for robotic surgeons. Our analysis revealed that surgeons posted more frequently on midweek days, and further that text posts received significantly more comments, and significantly fewer "likes," than posts containing links, photos, or videos. We discuss the implications of these use and engagement patterns for the viability of social media platforms as tools for surgeons to learn vicariously from their peers' experiences and expertise.

    The present study demonstrates the consequences of animal exposure to an enriched environment compared to animals living in a standard environment regarding learning and space memory. Male albino Wistar rats were exposed to an enriched environment for 4 weeks after the lactation period and tested in the Morris water maze in the distal and proximal clue version and in the arena. In the former test, the animals were tested at 50 days of age with 12 daily trials on two consecutive days. At the end of each session, scopolamine at the dose of 0.6 mg/kg/ml or saline solution was injected intraperitoneally. Twenty-eight days after the first phase, a new test consisting of a single trial was held (retest). An independent group of animals receiving no drug was subjected to the arena test and to the proximal clue version of the Morris maze. In the distal clue version the results did not show differences between groups in the first phase of the experiment. After 28 days (retest), the animals reared in a standard environment and treated with scopolamine exhibited a significant increase in latency compared to the group receiving the same drug and stimulated and to the group receiving saline. The arena data demonstrated a significant increase in exploratory activity in the group of animals reared in an enriched environment. The proximal clue version of the Morris maze did not show differences between groups. The results of the present study indicate that animals exposed to environmental enrichment react less to the amnesic effects of scopolamine and show an increase in exploratory activity.

LectureTools is an online platform that provides a suite of cloud-based teaching and learning applications. It combines the functions of interactive presentation, real-time student response system, student inquiry and online note-taking synchronised with the presentation slides, into one cloud-based platform. A comprehensive study investigated the effectiveness of the platform for enhancing student motivation among graduate (n=158 and undergraduate (n=96 students. Both groups of students reported enhanced motivation when using LectureTools. The scores on all six learning motivation scales of the Motivated Strategies for Learning Questionnaire, a psychometric instrument based on the cognitive view of motivation, increased when students engaged with the tool in class. Those who used the tool scored significantly higher on intrinsic goal orientation than those who did not use the tool. The students’ quantitative feedback showed that they found the tool useful and that it improved their motivation. Qualitative feedback from the instructors indicated that the tool was useful for engaging passive students. They reported that the most useful function was the interactive online questions with real-time results, while the in-class student inquiry function was difficult to use in practice.

    The appeal of online education and distance learning as an educational alternative is ever increasing. To support and accommodate the over-specialized knowledge available by different experts, information technology can be employed to develop virtual distributed pools of autonomous specialized educational modules and provide the mechanisms for retrieving and sharing them. New educational standards such as SCORM and Healthcare LOM enhance this process of sharing by offering qualities like interoperability, accessibility, and reusability, so that learning material remains credible, up-to-date and tracks changes and developments of medical techniques and standards through time. Given that only a few e-learning courses exist in aerospace medicine the material of which may be exchanged among teachers, the aim of this paper is to illustrate the procedure of creating a SCORM compliant course that incorporates notions of recent advances in social web technologies. The course is in accordance with main educational and technological details and is specific to pulmonary disorders in aerospace medicine. As new educational trends place much emphasis in continuing medical education, the expansion of a general practitioner's knowledge in topics such as aviation and aerospace pulmonary disorders for crew and passengers becomes a societal requirement.

    Highlights: • An integrated platform for quantitative N-glycoproteome analysis was established. • On-line enrichment, deglycosylation and labeling could be achieved within 160 min. • A N{sub 2}-assisted interface was applied to improve the compatibility of the platform. • The platform exhibited improved quantification accuracy, precision and throughput. - Abstract: Relative quantification of N-glycoproteomes shows great promise for the discovery of candidate biomarkers and therapeutic targets. The traditional protocol for quantitative analysis of glycoproteomes is usually off-line performed, and suffers from long sample preparation time, and the risk of sample loss or contamination due to manual manipulation. In this study, a novel integrated sample preparation platform for quantitative N-glycoproteome analysis was established, with combination of online N-glycopeptide capture by a HILIC column, sample buffer exchange by a N{sub 2}-assisted HILIC–RPLC interface, deglycosylation by a hydrophilic PNGase F immobilized enzymatic reactor (hIMER) and solid dimethyl labeling on a C18 precolumn. To evaluate the performance of such a platform, two equal aliquots of immunoglobulin G (IgG) digests were sequentially pretreated, followed by MALDI-TOF MS analysis. The signal intensity ratio of heavy/light (H/L) labeled deglycosylated peptides with the equal aliquots was 1.00 (RSD = 6.2%, n = 3), much better than those obtained by the offline protocol, with H/L ratio as 0.76 (RSD = 11.6%, n = 3). Additionally, the total on-line sample preparation time was greatly shortened to 160 min, much faster than that of offline approach (24 h). Furthermore, such an integrated pretreatment platform was successfully applied to analyze the two kinds of hepatocarcinoma ascites syngeneic cell lines with high (Hca-F) and low (Hca-P) lymph node metastasis rates. For H/L labeled Hca-P lysates with the equal aliquots, 99.6% of log 2 ratios (H/L) of quantified glycopeptides ranged from −1

    2013-02-01

    Full Text Available This paper explores augmented reality as a set of technologies and processes that weave hypermedial content into printed publications thus fostering new educational practices. The idea was to implement a platform fostering what has been defined as 'Mode-2' knowledge production practice. This is a practice that involves multi-disciplinary teams, brought together for short periods of time to work on specific, complex problems in the real world. In particular this paper focuses on augmented reality as a bridge to extend traditional hypermediality to paper-based educational tools, analyzing as case study a book recently released by the Italian publisher FakePress. The book addresses the concept of remix as a political and educational practice and is based on an extensive use of QR codes and fiduciary markers that act as triggers to retrieve and show additional content published by both authors and readers through an open CMS (Content Management System. The QR codes and the fiduciary markers work as links to hypermedial remixes that extend the limits of traditional educational text books.

    Background: This study combines work on concept mapping with scripted collaborative learning. Purpose: The objective was to examine the effects of self-regulated science learning through scripting students' argumentative interactions during collaborative 'multimedia-enriched skeleton concept mapping' on meaningful science learning and retention. Programme description: Each concept in the enriched skeleton concept map (ESCoM) contained annotated multimedia-rich content (pictures, text, animations or video clips) that elaborated the concept, and an embedded collaboration script to guide students' interactions. Sample: The study was performed in a Biomolecules course on the Bachelor of Applied Science program in the Netherlands. All first-year students (N=93, 31 women, 62 men, aged 17-33 years) took part in this study. Design and methods: The design used a control group who received the regular course and an experimental group working together in dyads on an ESCoM under the guidance of collaboration scripts. In order to investigate meaningful understanding and retention, a retention test was administered a month after the final exam. Results: Analysis of covariance demonstrated a significant experimental effect on the Biomolecules exam scores between the experimental group and the control, and the difference between the groups on the retention test also reached statistical significance. Conclusions: Scripted collaborative multimedia ESCoM mapping resulted in meaningful understanding and retention of the conceptual structure of the domain, the concepts, and their relations. Not only was scripted collaborative multimedia ESCoM mapping more effective than the traditional teaching approach, it was also more efficient in requiring far less teacher guidance.

    An increasingly popular method of assessing cognitive functions in rodents is the automated touchscreen platform, on which a number of different cognitive tests can be run in a manner very similar to touchscreen methods currently used to test human subjects. This methodology is low stress (using appetitive rather than aversive reinforcement), has high translational potential and lends itself to a high degree of standardization and throughput. Applications include the study of cognition in rodent models of psychiatric and neurodegenerative diseases (e.g., Alzheimer's disease, schizophrenia, Huntington's disease, frontotemporal dementia), as well as the characterization of the role of select brain regions, neurotransmitter systems and genes in rodents. This protocol describes how to perform four touchscreen assays of learning and memory: visual discrimination, object-location paired-associates learning, visuomotor conditional learning and autoshaping. It is accompanied by two further protocols (also published in this issue) that use the touchscreen platform to assess executive function, working memory and pattern separation.

    Technology enhanced learning or eLearning allows educators to expand access to educational content, promotes engagement with students and makes it easier for students to access educational material at a time, place and pace which suits them. The challenge for educators beginning their eLearning journey is to decide where to start, which includes the choice of an eLearning tool and platform. This article will share one educator's decision making process, and experience using blogs as a flexible and versatile integrated eLearning tool and platform. Apart from being a cost effective/free tool and platform, blogs offer the possibility of creating a hyperlinked indexed content repository, for both created and curated educational material; as well as a distribution and engagement tool and platform. Incorporating pedagogically sound activities and educational practices into a blog promote a structured templated teaching process, which can be reproduced. Moving from undergraduate to postgraduate training, educational blogs supported by a comprehensive online case-based repository offer the possibility of training beyond competency towards proficiency and expert level performance through a process of deliberate practice. By documenting educational content and the student engagement and learning process, as well as feedback and personal reflection of educational sessions, blogs can also form the basis for a teaching portfolio, and provide evidence and data of scholarly teaching and educational scholarship. Looking into the future, having a collection of readily accessible indexed hyperlinked teaching material offers the potential to do on the spot teaching with illustrative material called up onto smart surfaces, and displayed on holographic interfaces.

    Full Text Available Business failure is an intrinsic characteristic of entrepreneurship. Given its dimension and repercussions, we consider that entrepreneurial education, in particular entrepreneurial e-learning platforms should include a module on business failure covering in addition to the national legal framework and EU policies, the key barriers faced by entrepreneurs and causes of business failure and other such elements. Thus, we propose to develop a platform based on open source software, such as Moodle in which modules based on SCORM and interactive teaching have been developed, with all the tools that are needed to simulate classic teaching.

    Nowadays, open-source developments in the field of natural hazards and risk management increase rapidly. The governments, NGOs and other research institutes are producing data for risk and disaster analysis, but a few platforms are available to bring a real-life experience to the students. This work focuses on the preliminary results of testing a WebGIS platform called RISKGIS with the bachelor students at the University of Lausanne. The platform is designed based on a geospatial open-source technology called OpenGeo (Boundless). This platform can calculate the potential risk of the buildings and assist the students to understand the situations for risk reduction mitigation and decision-making. The center of Jomsom in Nepal was selected for the first exercise that may be affected by amplifications of earthquake. The shaking intensity map was designed by an expert based on the geological characteristics and DEM (Digital Elevation Model) of the area. All buildings data were extracted from OpenStreetMap using QGIS and adapted to the platform. The video tutorial was prepared to guide the students through the platform, and 80 students have tested the application online successfully and 40 of them participated in Moodle (a free Open Source software package for educators) for online feedback and quiz. Among those, 30 of them have completely answered to both. We had interesting results for effectiveness, efficiency and satisfaction based on System Usability Scale (SUS). The SUS score for this platform was 68.6 out of 100. The average result of the quiz was 9.39 out of 10 with a duration of 8 to 33 minutes to answer the quiz. There were several outliers for this duration with 2 minutes (two students) and 9 to 18 hours (three students). Further exercises will be carried out with students by adding more advanced functions to the platform and improving the willingness of participation in this online learning platform.

    This study is intended to examine the effect of pretreatment on selective enrichment of electrogenic bacteria from mixed culture. It has been observed that the iodopropane and heat-shock pretreatments suppress the growth of non-exoelectrons, while selecting only a limited number of strains belonging to genera Xanthomonas, Pseudomonas and Prevotella while untreated control inoculum showed more diverse community comprising of both exoelectrogens and non-exoelectrogens. High power output was observed in iodopropane (180mW/m(2)) pretreated microbial fuel cell (MFC) compared to heat-shock pretreated MFC (128mW/m(2)) and untreated control (92mW/m(2)). Coulombic efficiency of iodopropane and heat-shock pretreated MFC was higher compared to untreated control MFC, while drop in pH and volatile fatty acids (VFA) production was less in iodopropane pretreated MFC signifying the shifts in bacterial community structure toward electrogenesis instead of fermentation. These results signify the role of iodopropane and heat pretreatments on enrichment of electrogenic bacteria for fuel cell application.

    The increasing complexity of medical curricula would benefit from adaptive computer supported collaborative learning systems that support study management using instructional design and learning object principles. However, to our knowledge, there are scarce reports regarding applications developed to meet this goal and encompass the complete medical curriculum. The aim of ths study was to develop and assess the usability of an adaptive computer supported collaborative learning system for medical students to manage study sessions. A study platform named ALERT STUDENT was built as a free web application. Content chunks are represented as Flashcards that hold knowledge and open ended questions. These can be created in a collaborative fashion. Multiple Flashcards can be combined into custom stacks called Notebooks that can be accessed in study Groups that belong to the user institution. The system provides a Study Mode that features text markers, text notes, timers and color-coded content prioritization based on self-assessment of open ended questions presented in a Quiz Mode. Time spent studying and Perception of knowledge are displayed for each student and peers using charts. Computer supported collaborative learning is achieved by allowing for simultaneous creation of Notebooks and self-assessment questions by many users in a pre-defined Group. Past personal performance data is retrieved when studying new Notebooks containing previously studied Flashcards. Self-report surveys showed that students highly agreed that the system was useful and were willing to use it as a reference tool. The platform employs various instructional design and learning object principles in a computer supported collaborative learning platform for medical students that allows for study management. The application broadens student insight over learning results and supports informed decisions based on past learning performance. It serves as a potential educational model for the medical

    In recent years there has been a rapid increase in the size of video and image databases. Effective searching and retrieving of images from these databases is a significant current research area. In particular, there is a growing interest in query capabilities based on semantic image features such as objects, locations, and materials, known as content-based image retrieval. This study investigated mechanisms for identifying materials present in an image. These capabilities provide additional information impacting conditional probabilities about images (e.g. objects made of steel are more likely to be buildings). These capabilities are useful in Building Information Modeling (BIM) and in automatic enrichment of images. I2T methodologies are a way to enrich an image by generating text descriptions based on image analysis. In this work, a learning model is trained to detect certain materials in images. To train the model, an image dataset was constructed containing single material images of bricks, cloth, grass, sand, stones, and wood. For generalization purposes, an additional set of 50 images containing multiple materials (some not used in training) was constructed. Two different supervised learning classification models were investigated: a single multi-class SVM classifier, and multiple binary SVM classifiers (one per material). Image features included Gabor filter parameters for texture, and color histogram data for RGB components. All classification accuracy scores using the SVM-based method were above 85%. The second model helped in gathering more information from the images since it assigned multiple classes to the images. A framework for the I2T methodology is presented.

    Full Text Available The emergence of mobile platforms with increased storage and computing capabilities and the pervasive use of these platforms for sensitive applications such as online banking, e-commerce and the storage of sensitive information on these mobile devices have led to increasing danger associated with malware targeted at these devices. Detecting such malware presents inimitable challenges as signature-based detection techniques available today are becoming inefficient in detecting new and unknown malware. In this research, a machine learning approach for the detection of malware on Android platforms is presented. The detection system monitors and extracts features from the applications while in execution and uses them to perform in-device detection using a trained K-Nearest Neighbour classifier. Results shows high performance in the detection rate of the classifier with accuracy of 93.75%, low error rate of 6.25% and low false positive rate with ability of detecting real Android malware.

    Full Text Available Embodiment theory proposes that knowledge is grounded in sensorimotor systems, and that learning can be facilitated to the extent that lessons can be mapped to these systems. This study with 109 college-age participants addresses two overarching questions: a how are immediate and delayed learning gains affected by the degree to which a lesson is embodied, and b how do the affordances of three different educational platforms affect immediate and delayed learning? Six 50 minute-long lessons on centripetal force were created. The first factor was the degree of embodiment with two levels: 1 low and 2 high. The second factor was platform with three levels: 1 a large scale mixed reality immersive environment containing both digital and hands-on components called SMALLab, 2 an interactive whiteboard system, and 3 a mouse-driven desktop computer. Pretests, posttests, and one-week followup (retention or delayed learning gains tests were administered resulting in a 2 x 3 x 3 design. Two knowledge subtests were analyzed, one that relied on more declarative knowledge and one that relied on more generative knowledge, e.g., hand-drawing vectors. Regardless of condition, participants made significant immediate learning gains from pretest to posttest. There were no significant main effects or interactions due to platform or embodiment on immediate learning. However, from posttest to followup the level of embodiment interacted significantly with time, such that participants in the high embodiment conditions performed better on the subtest devoted to generative knowledge questions. We posit that better retention of certain types of knowledge can be seen over time when more embodiment is present during the encoding phase. This sort of retention may not appear on more traditional factual/declarative tests. Educational technology designers should consider using more sensorimotor feedback and gestural congruency when designing and opportunities for instructor

Three-month-old animals were maintained for a month alone (AL, alone in a physically enriched environment (PHY, and, finally, in groups in the absence (SO or presence (SOPHY of an enriched environment. The animals' capabilities were subsequently checked in the rotarod test, and for classical and instrumental learning. The PHY and SOPHY groups presented better performances in the rotarod test and in the acquisition of the instrumental learning task. In contrast, no significant differences between groups were observed for classical eyeblink conditioning. The four groups presented similar increases in the strength of field EPSPs (fEPSPs evoked at the hippocampal CA3-CA1 synapse across classical conditioning sessions, with no significant differences between groups. These trained animals were pulse-injected with bromodeoxyuridine (BrdU to determine hippocampal neurogenesis. No significant differences were found in the number of NeuN/BrdU double-labeled neurons. We repeated the same BrdU study in one-month-old mice raised for an additional month in the above-mentioned four different environments. These animals were not submitted to rotarod or conditioned tests. Non-trained PHY and SOPHY groups presented more neurogenesis than the other two groups. Thus, neurogenesis seems to be related to physical enrichment at early ages, but not to learning acquisition in adult mice.

    Full Text Available A capacity for self-regulated learning (SRL has long been recognised as an important factor in successful studies. Although educational researchers have started to investigate the concept of SRL in the context of online education, very little is yet known about SRL in relation to massive open online courses (MOOCs or of appropriate strategies to foster SRL skills in MOOC learners. Self-regulation is particularly important in a MOOC-based study, which demands effective independent learning, and where widely acknowledged high dropout rates are observed. This study reports an investigation and assessment of the concept of SRL using a novel MOOC platform (eLDa by providing study options (either via a self-directed learning or instructor-led learning using a novel learning tool. In view of this, the research presents general description of self-regulated learning and explored the various existing dimensions used to expose the learners SRL skills. Drawing comparison of the online tool, the results and findings of the data were analysed. The study dis¬cusses how the various dimensions contributed to the knowledge representation of the self-regulated learning abilities shown by the learners. We present how these SRL dimensions captured using the measuring instrument contributes to our growing understanding of the distinctive features of the individual learner’s self-regulated learning. MOOCs success required a high performance of self-regulated learning abilities which at the moment very little has shown these degree of supporting SRL skills. This paper presents preliminary evaluation of a novel e-learning tool known, as ‘eLDa’ developed to implement this investi¬gation of self-regulation of learning. The research applied a modified online self-regulated learning questionnaire (OSLQ as the instrument to measure the SRL skills. The modified questionnaire known as MOOC OSLQ (MOSLQ was developed with a 19-item scale questions that exposes the six

    Hendrix, Rebecca Compton

    This study made analysis of how the integration of creative drama into a science enrichment program enhanced the learning of elementary school students' understanding of sound physics and solar energy. The study also sought to determine if student attitudes toward science could be improved with the inclusion of creative drama as an extension to a well-known science inquiry program. The qualitative portion of this study explored the treatment groups' perceptions of how the use of creative drama helped them to learn science. A treatment group of fourth and fifth grade students were taught using the Full Option Science System (FOSS) kit in sound physics and solar energy with the inclusion of creative drama, while a control group of fourth and fifth grade students were taught using only the FOSS kit. The quantitative data analysis revealed that the students who were taught science with the inclusion of creative drama showed greater understanding of the science content than the students in the control group taught without the inclusion of creative drama. Both groups and grade levels in this study showed a slight decline in science attitudes from pre to post survey. Although the overall change was small it was statistically significant. The conclusion from this data is that the inclusion of creative drama in a science inquiry science program does not increase student's attitudes toward learning science any better than inquiry based instruction without creative drama. The drama treatment group students reported that they enjoyed participating in creative drama activities and generally viewed the creative drama intervention as a fun way to learn more about science. The students indicated that the creative drama activities helped them to remember and think about science. The researcher concluded that creative drama when used as an extension to an inquiry science program increases student understanding of science content better than the use of a science inquiry program alone

    Spectral Tarsier is a primitive primate that can only be found in the province of North Sulawesi. To study these primates can be used an e-learning application with Augmented Reality technology that uses a marker to confronted the camera computer to interact with three dimensions Tarsier object. But that application only shows tarsier object in three dimensions without habitat and requires a lot of resources because it runs on a Personal Computer. The same technology can be shown three dimensions’ objects is Virtual Reality to excess can make the user like venturing into the virtual world with Android platform that requires fewer resources. So, put on Virtual Reality technology using the Android platform that can make users not only to view and interact with the tarsiers but also the habitat. The results of this research indicate that the user can learn the Tarsier and habitat with good. Thus, the use of Virtual Reality technology in the e-learning application of tarsiers can help people to see, know, and learn about Spectral Tarsier.

    Full Text Available Abstract Background Retinal photoreceptors are highly specialised cells, which detect light and are central to mammalian vision. Many retinal diseases occur as a result of inherited dysfunction of the rod and cone photoreceptor cells. Development and maintenance of photoreceptors requires appropriate regulation of the many genes specifically or highly expressed in these cells. Over the last decades, different experimental approaches have been developed to identify photoreceptor enriched genes. Recent progress in RNA analysis technology has generated large amounts of gene expression data relevant to retinal development. This paper assesses a machine learning methodology for supporting the identification of photoreceptor enriched genes based on expression data. Results Based on the analysis of publicly-available gene expression data from the developing mouse retina generated by serial analysis of gene expression (SAGE, this paper presents a predictive methodology comprising several in silico models for detecting key complex features and relationships encoded in the data, which may be useful to distinguish genes in terms of their functional roles. In order to understand temporal patterns of photoreceptor gene expression during retinal development, a two-way cluster analysis was firstly performed. By clustering SAGE libraries, a hierarchical tree reflecting relationships between developmental stages was obtained. By clustering SAGE tags, a more comprehensive expression profile for photoreceptor cells was revealed. To demonstrate the usefulness of machine learning-based models in predicting functional associations from the SAGE data, three supervised classification models were compared. The results indicated that a relatively simple instance-based model (KStar model performed significantly better than relatively more complex algorithms, e.g. neural networks. To deal with the problem of functional class imbalance occurring in the dataset, two data re

    Large, publicly available gene expression datasets are often analyzed with the aid of machine learning algorithms. Although RNA-seq is increasingly the technology of choice, a wealth of expression data already exist in the form of microarray data. If machine learning models built from legacy data can be applied to RNA-seq data, larger, more diverse training datasets can be created and validation can be performed on newly generated data. We developed Training Distribution Matching (TDM), which transforms RNA-seq data for use with models constructed from legacy platforms. We evaluated TDM, as well as quantile normalization, nonparanormal transformation, and a simple log 2 transformation, on both simulated and biological datasets of gene expression. Our evaluation included both supervised and unsupervised machine learning approaches. We found that TDM exhibited consistently strong performance across settings and that quantile normalization also performed well in many circumstances. We also provide a TDM package for the R programming language.

    Full Text Available The development of new technologies is found inevitable and children interests toward online platforms and virtual worlds are rapidly growing. In addition, there is a consensus that use of technology for primary or secondary school education is effective for achievement and motivation. In research and practice there are many educational implementations of technology in classrooms that were found useful.Similar to most qualitative studies, the purpose of this study also cannot be narrowed down to a single sentence but the overarching aim of the study is to explore the nature of using virtual worlds as a learning platform during. The theoretical background of this study is rooted from the constructivism and constructionism learning approaches. Consisted with its theoretical framework, this study has followed a qualitative case study research method to explore the nature of the construct. The case is a bounded system that is narrowed to a single case (Merriam, 1988; Stake, 1995; Yin, 2003. There are various types of data collected within this system. Based on the data collected and the research-suggested case study data analysis approaches, the following themes were emerged; realty, learning by discovering, learning by design, scaffolding and chunking information, and real life desires.After using Whyville virtual platform, the aim of this study was expected to start new discussion on young children using more complex virtual worlds such as Second Life. Thus, the results of this study could be guidance for transmission process of children toward Second Life type of virtual worlds. Even though a further discussion may need about the nature of using the virtual worlds, the primary findings of these case studies suggest some practical implications for children’s education.

    One of the key elements of e-learning platforms is the content provided to the students. Content creation is a time demanding task that requires teachers to prepare material taking into account that it will be accessed on-line. Moreover, the teacher is restricted by the functionalities provided by the e-learning platforms. In contexts such as radiology where images have a key role, the required functionalities are still more specific and difficult to be provided by these platforms. Our purpose is to create a framework to make teacher's tasks easier, specially when he has to deal with contents where images have a main role. In this paper, we present RadEd, a new web-based teaching framework that integrates a smart editor to create case-based exercises that support image interaction such as changing the window width and the grey scale used to render the image, taking measurements on the image, attaching labels to images and selecting parts of the images, amongst others. It also provides functionalities to prepare courses with different topics, exercises and theory material, and also functionalities to control students' work. Different experts have used RadEd and all of them have considered it a very useful and valuable tool to prepare courses where radiological images are the main component. RadEd provides teachers functionalities to prepare more realistic cases and students the ability to make a more specific diagnosis. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Marginalised young people who find themselves disadvantaged in a number of respects also tend to experience limited access to Information and Communication Technologies (ICT – with the exception of mobile phones. The European Commission-funded ComeIn project seeks to take advantage of marginalised young people’s access to mobile phones by reaching out to them via an innovative pedagogical approach based on the media convergence of the mobile phone through an online platform with video streaming. The platform was developed specifically for the purposes of the project to create the possibility for new, positive learning experiences as well as for interaction with peers and youth workers. In a three-month study in Austria and the United Kingdom, 94 young people accessed the platform via their mobile phones. In this paper we discuss the appropriateness of media convergence as a means for learning in and across three dimensions: interaction, creative expression and self-organisation. Furthermore, we explore how to incorporate initiatives such as ComeIn in an institutionalised context.

    This pilot study compared the use of an enriched multimedia eBook with traditional methods for teaching the gross anatomy of the heart and great vessels. Seventy-one first-year students from an Australian medical school participated in the study. Students' abilities were examined by pretest, intervention, and post-test measurements. Perceptions and attitudes toward eBook technology were examined by survey questions. Results indicated a strongly positive user experience coupled with increased marks; however, there were no statistically significant results for the eBook method of delivery alone outperforming the traditional anatomy practical session. Results did show a statistically significant difference in the final marks achieved based on the sequencing of the learning modalities. With initial interaction with the multimedia content followed by active experimentation in the anatomy lab, students' performance was improved in the final test. Obtained data support the role of eBook technology in modern anatomy curriculum being a useful adjunct to traditional methods. Further study is needed to investigate the importance of sequencing of teaching interventions.

    Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for several purposes to anyone interested in creating interactive objects or environments. The hydraulic matters teach at the Agricultural Engineering School at the Technical University of Madrid deal with practical issues regarding the measurement of variables such as pressure, discharge, temperature and soil water content. Most of the data loggers available in the market for these variables at expensive and not always affordable. On the other hand, current students are eager to manage new technological devices thus, their skills could be oriented not only to the application of an electronic platform as Arduino to build low cost data loggers for different purposes, but to encourage their learning in the hydraulic matters improving their self esteem

    structure of Learning Management System (LMS has been investigated by the asynchronous working group. A needs analysis has been conducted so as to determine the features of the system to be designed later throughout the process. In the light of the data achieved, the minimum software knowledge to be possessed by the members of the group has been defined. Following the literature review, the synchronous working group has examined the structure of the synchronous interfaces used in the existing distance learning systems. The characteristics of these systems as well as their capabilities were then determined.3. FindingsWithin the framework of this research, the findings achieved from the logs (diaries of the participants reflect their experiences both before and during the design process of the distance learning system. As a result of the qualitative analysis, through the study processes themes such as „preparedness, expectations, preparations, problems, solutions and recommendations‟ have been formed.4. Conclusion and RecommendationsThe most important criteria for achieving success in designing a distance learning system is to conduct a good analysis of situation, elucidate the differences between current state and requirements conduct a group work for finding solutions for determined defeicincies. Despite the fact that a needs analysis has been conducted and the operation plan of the system has been prepared prior to the design of the system. However, the participants still encounter some problems during the process. This is because any study conducted prior to the design of such complicated systems only contribute to the formation of the infrastructure of the system and thus be beneficial for the participants. Not only the synchronic level but also the platform through which the system shall be supported is also very important while designing the system. Therefore, it is very crucial at this point that the LMS is designed as a dynamic one. Distance learning systems are

As the e-learning platform approach is becoming an important tool to allow the flexibility and quality requested by such a kind of learning process. There is a new kind of problem faced by organizations consisting in the selection of the most suitable e-learning platform. This paper proposes evaluation model for E-Learning platform in Riyadh City universities (RCU with Applied Geographic Information System (GIS. The E-Learning platform solution selection is a multiple criteria decision-making problem that needs to be addressed objectively taking into consideration the relative weights of the criteria for any organization. We formulate the quoted multi criteria problem as a decision hierarchy to be solved using GIS. AGIS-based evaluation index system and web-based evaluating platform were established. In this paper we will show the general evaluation strategy and some obtained results using our model to evaluate some existing commercial platforms.The results of evaluation model are outlined as follows: Total weights of the proposed framework in management feature is 20.25/25, in collaborative feature is 9.2/10, in adaption learning path is 6.8/10 and in interactive learning object is 5/5. The total weights of all features are 41.25/50. In this study an evaluation model was applied on Riyadh City universities like KSU, IMAMU, NAUSS, YU and FU. Then, the results were compared with each other. The total weighs of KSU was 41. While the total weights of FU, IMAMU, YU and NAUSS was 40, 37, 36 and 32, respectively. Evaluation process shows that the proposed framework satisfied the objectives with applied GIS.

    Astroinformatics is a new impact area in the world of astronomy, occasionally called the final frontier, where several astrophysicists, statisticians and computer scientists work together to tackle various data intensive astronomical problems. Exponential growth in the data volume and increased complexity of the data augments difficult questions to the existing challenges. Classical problems in Astronomy are compounded by accumulation of astronomical volume of complex data, rendering the task of classification and interpretation incredibly laborious. The presence of noise in the data makes analysis and interpretation even more arduous. Machine learning algorithms and data analytic techniques provide the right platform for the challenges posed by these problems. A diverse range of open problem like star-galaxy separation, detection and classification of exoplanets, classification of supernovae is discussed. The focus of the paper is the applicability and efficacy of various machine learning algorithms like K N...

  19. Proposal of an enriched three-tier test to assess learning risks in students on undergraduate physics courses

    CERN Document Server

    2014-01-01

    This proposal presents a methodology called enriched three-tier test, based on a similar test previously discussed in the literature. Ours consists of the use of justification and degrees of confidence combined with a multiple-choice test. This methodology of assessment allows the teacher to diagnose learning risks, while engaging the student in a metacognitive process. The three-tier test proved to be an efficient mechanism for identifying up to eighteen tints along the learning spectrum for a single concept, which interpretation alerts the teacher about the existence of learning risks and other learning situations. In this proposal, we explain the three-tier structure; we comment on it's application to undergraduate students from two semestral courses, and we analyze the category spectrum that a three-tier test produces, discussing it's differences with a traditional multiple choice question, it's limitations, and possible new applications.

    Dependability of electronic circuits can be ensured only through testing of circuit modules. This is done by generating test vectors and their application to the circuit. Testability should be viewed as a concerted effort to ensure maximum efficiency throughout the product life cycle, from conception and design stage, through production to repairs during products operating. In this paper, is presented the platform developed by authors for training for testability in electronics, in general and in using signature analysis method, in particular. The platform allows highlighting the two approaches in the field namely analog and digital signature of circuits. As a part of this e-learning platform, it has been developed a database for signatures of different electronic components meant to put into the spotlight different techniques implying fault detection, and from this there were also self-repairing techniques of the systems with this kind of components. An approach for realizing self-testing circuits based on MATLAB environment and using signature analysis method is proposed. This paper analyses the benefits of signature analysis method and simulates signature analyzer performance based on the use of pseudo-random sequences, too.

    2015-02-01

    Full Text Available This paper explores the application of canonical gradient analysis to evaluate and visualize student performance and acceptance of a learning system platform. The subject of evaluation is a first year BSc module for computer programming. This uses ‘Ceebot’, an animated and immersive game-like development environment. Multivariate ordination approaches are widely used in ecology to explore species distribution along environmental gradients. Environmental factors are represented here by three ‘assessment’ gradients; one for the overall module mark and two independent tests of programming knowledge and skill. Response data included Likert expressions for behavioral, acceptance and opinion traits. Behavioral characteristics (such as attendance, collaboration and independent study were regarded to be indicative of learning activity. Acceptance and opinion factors (such as perceived enjoyment and effectiveness of Ceebot were treated as expressions of motivation to engage with the learning environment. Ordination diagrams and summary statistics for canonical analyses suggested that logbook grades (the basis for module assessment and code understanding were weakly correlated. Thus strong module performance was not a reliable predictor of programming ability. The three assessment indices were correlated with behaviors of independent study and peer collaboration, but were only weakly associated with attendance. Results were useful for informing teaching practice and suggested: (1 realigning assessments to more fully capture code-level skills (important in the workplace; (2 re-evaluating attendance-based elements of module design; and (3 the overall merit of multivariate canonical gradient approaches for evaluating and visualizing the effectiveness of a learning system platform.

    The GLOBE program has provided opportunities for environmental science research and education collaborations among scientists, teachers and K-12 students, and for cross-cultural enrichment nationally and abroad. In Alaska, GLOBE has also provided funding leverage in some cases, and a base for several other science education programs that share a common goal of increasing student interest, understanding, process skills and achievement in science, through involvement in ongoing research investigations. These programs that use GLOBE methodologies (standardized scientific measurements and learning activities developed by scientists and educators) are: Global Change Education Using Western Science and Native Knowledge also known as "Observing Locally, Connecting Globally" (OLCG); Alaska Earth System Science Education Alliance: Improving Understanding of Climate Variability and Its Relevance to Rural Alaska; Schoolyard Long Term Ecological Research; Alaska Rural Research Partnership; Alaska Partnership for Teacher Enhancement; Alaska Lake Ice and Snow Observatory Network; Alaska Boreal Forest Council Education Outreach; Calypso Farm and Ecology Center; Environmental Education Outreach; and also GLOBE Arctic POPs (persistent organic pollutants) a program that involves countries in the circumpolar North. The University of Alaska GLOBE Partnership has collaborated with the BLM Campbell Creek Science Center Globe Partnership in facilitating GLOBE Training Workshops and providing teacher support. GLOBE's extensive website including data entry, archive, analysis and visualization capabilities; GLOBE Teacher Guide, videos and other materials provided; excellent GLOBE science research and education staff, training support office, GLOBE help desk, alignment of GLOBE curriculum with national science education standards and GLOBE certification of teachers trained on even just one GLOBE investigation, have made it easier to implement GLOBE in the classroom.

    2012-06-01

    Full Text Available Second Life (SL is an ideal platform for language learning. It is called a Multi-User Virtual Environment, where users can have varieties of learning experiences in life-like environments. Numerous attempts have been made to use SL as a platform for language teaching and the possibility of SL as a means to promote conversational interactions has been reported. However, the research so far has largely focused on simply using SL without further augmentations for communication between learners or between teachers and learners in a school-like environment. Conversely, not enough attention has been paid to its controllability which builds on the embedded functions in SL. This study, based on the latest theories of second language acquisition, especially on the Task Based Language Teaching and the Interaction Hypothesis, proposes to design and implement an automatized interactive task space (AITS where robotic agents work as interlocutors of learners. This paper presents a design that incorporates the SLA theories into SL and the implementation method of the design to construct AITS, fulfilling the controllability of SL. It also presents the result of the evaluation experiment conducted on the constructed AITS.

    Full Text Available Education and training are expected to change dramatically due to the combined impact of the Internet and multimedia technologies. A challenge for internet-based education systems is to allow educators and trainers to work from known models, while simultaneously letting them experiment with innovations without requiring frequent retooling. Work in distance learning, while of interest in its own right, is important to our general research program as a test bed for our ideas. The basic research program is to provide a general foundation, or set of "primitive" classes, for building remote collaboration environments, and then to build toolkits using these classes, and other more specific classes, that will address the particular requirements of various collaboration environments. Our basic premise is that the virtual room concept together with other fundamental concepts provides such a foundation. In this paper we discuss our virtual room platform and a distance-learning environment called PERSYST. PERSYST has been used in several distance-learning trials; we close this paper with a discussion of the trials and what we have learned from them.

    The resurgence of home hemodialysis (HHD) underlines the importance of educational programs. Brainstorming is a powerful tool for innovation, widely employed in industry but seldom used in medicine. The aim of this study was to define an e-learning Web platform for HHD patients via a brainstorming approach. Four brainstorming sessions were held 2-6 weeks apart. Twelve people were involved: 2 dialysis physicians, 2 nurses, 2 HHD patients, 2 caregivers, a filmmaker, 2 computer experts (1 with a psychology degree) and a senior engineer. Each session was summarized as the starting point for the following one. The topics discussed were the platform structure and its logo. For the platform, the following requirements were defined: teaching should be extensive and tailored to different levels of knowledge; all available teaching tools (tutorials, demonstrations, recorded and written materials) should be used; films enhance emotional participation and can be used to reduce fears; the contents should include general information on chronic kidney disease, details of all types of renal replacement therapy (RRT) (how and why), dialysis accidents, blood and imaging tests, laws and reimbursements, direct experiences and history of RRT. Remote monitoring and visual interactions are important for reassurance about HHD and should be provided. The requirements for the logo were that it be innovative, related to daily life, representative of a holistic approach and convey happiness. The logo "Hom-e-hem" was created, playing on the assonance between the religious term Om and the word home, with the e of electronic linking it with hem, short for hemodialysis. Brainstorming sessions can be used to design patient-tailored educational interventions. The key message, "self-care is a bridge from illness back to life," may apply to a wider context.

    Plant phenomics has received increasing interest in recent years in an attempt to bridge the genotype-to-phenotype knowledge gap. There is a need for expanded high-throughput phenotyping capabilities to keep up with an increasing amount of data from high-dimensional imaging sensors and the desire to measure more complex phenotypic traits (Knecht et al., 2016). In this paper, we introduce an open-source deep learning tool called Deep Plant Phenomics. This tool provides pre-trained neural networks for several common plant phenotyping tasks, as well as an easy platform that can be used by plant scientists to train models for their own phenotyping applications. We report performance results on three plant phenotyping benchmarks from the literature, including state of the art performance on leaf counting, as well as the first published results for the mutant classification and age regression tasks for Arabidopsis thaliana.

This tool provides pre-trained neural networks for several common plant phenotyping tasks, as well as an easy platform that can be used by plant scientists to train models for their own phenotyping applications. We report performance results on three plant phenotyping benchmarks from the literature, including state of the art performance on leaf counting, as well as the first published results for the mutant classification and age regression tasks for Arabidopsis thaliana.

    The development of 3D technology provides more advantages in education sectors. In chemistry, the 3D technology makes chemistry objects look more tangible. This research developed a monograph titled “Augmented Chemistry: Hydrocarbon” as learning enrichment materials. The development model consisted of 5 steps, which were the adaptation of the ADDIE model. The 3D objects of chemistry were built using the computer applications of Chem Sketch, and Google Sketch Up with AR Plugin. The 3D objects were displayed by relevant markers on the texts of the monograph from which the visualizations of the 3D objects appeared when they were captured by digital camera of laptop or smartphone, and were possibly viewed with free-rotation. Not only were 3D chemistry objects included in the monograph, but also graphics, videos, audios, and animations, which facilitated more fun learning for readers of the monograph. After the reviews by the experts of subject matter, of media, of instruction, and by peers, the monograph was revised, and then rated by chemistry teachers. The analysis of the data showed that the monograph titled “Augmented Chemistry: Hydrocarbon” was in the criteria of very good for the enrichment materials of Chemistry learning.

    Full Text Available Electronic learning platforms are evolving and their evaluation is becoming more complex and challenging with time. Yet, the evaluation of electronic learning services is intrinsically linked to improving the performance of documentation services. In this paper, I describe my perspectives on the design, use and evaluation of an electronic learning platform using a lens of a practitioner from a third world country. I further delineate the challenges and constraints I encountered as a student learning about e-learning platforms and using e-learning platform services at an institution of higher learning in Sweden. In particular, the Ping Pong system at the University of Boras, Sweden, and the electronic print in the Library and Information Science (E-LIS, one of the services from the bulletin board for libraries (BUBL Link information gateway, will be evaluated. It is anticipated that this experiential evaluation will provide designers of e-learning platforms with insights and strategies for refining the e-learning platform to facilitate teaching activities and promote students’ learning efficiency and satisfaction.

    The Morris water maze is routinely used to explore neurobiological mechanisms of working memory. Humans can often acquire working memory relevant to performing a task by mere sensory observation, without having to actually perform the task followed by reinforcement. This can be modeled in the water maze through direct placement of a rat on the escape platform so that it can observe the location, and then assessing the subject's performance in swimming back to the platform. However, direct placement procedures have hardly been studied for two decades, reflecting a controversy about whether direct placement resulted in sufficiently rapid and direct swims back to the platform. In the present study, utilizing revised training methods, a more comprehensive measure of trajectory directness, a more rigorous sham-trained control procedure and an optimal placement-test interval, rats swam almost directly back to the platform in under 4s, significantly more quickly and directly than sham-trained subjects. Muscarinic cholinergic mechanisms, which are inactivated by scopolamine, are essential to memory for standard learning paradigms in the water maze. This experiment determined whether this would also be true for latent learning. ANOVA revealed significant negative effects of scopolamine on both speed and accuracy of trajectory, as well as significant positive effects of direct placement training vs. sham-training. In a probe trial, placement-trained animals without scopolamine spent significantly more time and path length in the target quadrant than trained rats with scopolamine and sham-trained rats without scopolamine. Scopolamine impairments are likely due to effects on memory, since the same dose had little effect on performance with a visible platform. The revised direct placement model offers a means of further comparing the neural mechanisms of latent learning with those of standard instrumental learning.

  1. Comparison of Learning Software Architecture by Developing Social Applications versus Games on the Android Platform

    2012-01-01

    Full Text Available This paper describes an empirical study where the focus was on discovering differences and similarities in students working on development of social applications versus students working on development of games using the same Android development platform. In 2010-2011, students attending the software architecture course at the Norwegian University of Science and Technology (NTNU could choose between four types of projects. Independently of the chosen type of project, all students had to go through the same phases, produce the same documents based on the same templates, and follow exactly the same process. This study focuses on one of projects—Android project, to see how much the application domain affects the course project independently of the chosen technology. Our results revealed some positive effects for the students doing game development compared to social application development to learn software architecture, like motivated to work with games, a better focus on quality attributes such as modifiability and testability during the development, production of software architectures of higher complexity, and more productive coding working for the project. However, we did not find significant differences in awarded grade between students choosing the two different domains.

  2. Adapting Cell-Based Assays to the High Throughput Screening Platform: Problems Encountered and Lessons Learned.

    Maddox, Clinton B; Rasmussen, Lynn; White, E Lucile

    2008-06-01

    In recent years, cell-based phenotypic assays have emerged as an effective and robust addition to the array of assay technologies available for drug discovery in the high throughput screening arena. Previously, biochemical target-based assays have been the technology of choice. With the emergence of stem cells as a basis for a new screening technology, it is important to keep in mind the lessons that have been learned from the adaptation of existing stable cell lines onto the high throughput screening drug discovery platform, with special consideration being given to assay miniaturization, liquid handling complications and instrument-introduced artifacts. We present an overview of the problems encountered with the implementation of multiple cell-based assays at the High Throughput Screening Center at Southern Research Institute as well as empirically defined effective solutions to these problems. These include examples of artifacts induced by temperature differences throughout the screening campaign, cell plating conditions including the effect of room temperature incubation on assay consistency, DMSO carry-over, and incubator induced artifacts.

  3. The effect of an enriched learning community on success and retention in chemistry courses

    Science.gov (United States)

    Willoughby, Lois Jane

    Since the mid-1990s, the United States has experienced a shortage of scientists and engineers, declining numbers of students choosing these fields as majors, and low student success and retention rates in these disciplines. Learning theorists, educational researchers, and practitioners believe that learning environments can be created so that an improvement in the numbers of students who complete courses successfully could be attained (Astin, 1993; Magolda & Terenzini, n.d.; O'Banion, 1997). Learning communities do this by providing high expectations, academic and social support, feedback during the entire educational process, and involvement with faculty, other students, and the institution (Ketcheson & Levine, 1999). A program evaluation of an existing learning community of science, mathematics, and engineering majors was conducted to determine the extent to which the program met its goals and was effective from faculty and student perspectives. The program provided laptop computers, peer tutors, supplemental instruction with and without computer software, small class size, opportunities for contact with specialists in selected career fields, a resource library, and Peer-Led Team Learning. During the two years the project has existed, success, retention, and next-course continuation rates were higher than in traditional courses. Faculty and student interviews indicated there were many affective accomplishments as well. Success and retention rates for one learning community class ( n = 27) and one traditional class (n = 61) in chemistry were collected and compared using Pearson chi square procedures ( p = .05). No statistically significant difference was found between the two groups. Data from an open-ended student survey about how specific elements of their course experiences contributed to success and persistence were analyzed by coding the responses and comparing the learning community and traditional classes. Substantial differences were found in their

    Postoperative cognitive dysfunction (POCD) is a significant clinical syndrome. Neurogenesis contributes to cognition. It is known that enriched environment (EE) enhances neurogenesis. We determined whether EE attenuated surgery-induced cognitive impairment and whether growth factors and neurogenesis played a role in the EE effect. Eight-week-old C57BL/6J mice were subjected to carotid artery exposure. Their learning and memory were assessed by Barnes maze, and fear conditioning started 2 weeks after the surgery. Growth factor expression and cell genesis were determined at various times after the surgery. Surgery increased the time for the mice to identify the target hole in the Barnes maze and reduced context-related freezing behavior. Surgery also reduced the expression of brain-derived neurotrophic factor (BDNF) and neurogenesis in the hippocampus. These effects were attenuated by EE. EE also attenuated surgery-induced reduction of phosphorylated/activated tropomyosin-related kinase B (TrkB) and extracellular signal-regulated kinases (ERK), components of BDNF signaling pathway. ANA-12, a selective TrkB antagonist, blocked the effects of EE on cognition, phosphorylation of TrkB and ERK, and neurogenesis. These results provide initial evidence that surgery reduces BDNF expression and neurogenesis in the hippocampus. Our results suggest that EE reduces surgery-induced impairment of learning, memory, and neurogenesis by preserving BDNF expression.

    Cardiac telerehabilitation includes, in its most comprehensive format, telemonitoring, telecoaching, social interaction, and eLearning. The specific role of eLearning, however, was seldom assessed. The aim of eEduHeart I is to investigate the medium-term effectiveness of the addition of a cardiac web-based eLearing platform to conventional cardiac care. In this prospective, multicenter randomized, controlled trial, 1,000 patients with coronary artery disease will be randomized 1:1 to an intervention group (receiving 1-month unrestricted access to the cardiac eLearning platform in addition to conventional cardiac care) or to conventional cardiac care alone. The primary endpoint is health-related quality of life, assessed by the HeartQoL questionnaire at the 1- and 3-month follow-ups. Secondary endpoints include pathology-specific knowledge and self-reported eLearning platform user experience. Data on the eLearning platform usage will be gathered through web logging during the study period. eEduHeart I will be one of the first studies to report on the added value of eLearning. If the intervention is proven effective, current cardiac telerehabilitation programs can be augmented by including eLearning, too. The platform can then be used as a model for other chronic diseases in which patient education plays a key role. © 2016 S. Karger AG, Basel.

  11. Augmenting Learning in an Out-of-school Context: The Cognitive and Affective Impact of Two Cryogenics-based Enrichment Programmes on Upper Primary Students

    Caleon, Imelda S.; Subramaniam, R.

    2007-07-01

    Concepts learned in the classroom were reinforced and augmented by presenting them in a different context using cryogenics-based enrichment programmes (CBEPs) held in an out-of-school setting. The effectiveness of two CBEPs, which involve the use of liquid nitrogen and liquid oxygen, was explored. Using a sample of 265 upper primary students, it was found that both enrichment programmes were effective in promoting the learning of science concepts. Fair improvements, albeit only transient, in two attitude constructs, enjoyment of science and career preference, due to either CBEPs were detected. The CBEPs did not have any significant impact on the attitude construct relating to students’ views on the social implications of science. The impact of CBEPs showed signs of retention, specifically in the cognitive realm, and reasonable indications of influencing subsequent learning and activities of students.

    2015-08-01

    Full Text Available Heading control of an Unmanned Aerial Vehicle UAV is a vital operation of an autopilot system. It is executed by employing a design of control algorithms that control its direction and navigation. Most commonly available autopilots exploit Proportional-Integral-Derivative PID based heading controllers. In this paper we propose an online adaptive reinforcement learning heading controller. The autopilot heading controller will be designed in MatlabSimulink for controlling a UAV in X-Plane test platform. Through this platform the performance of the controller is shown using real time simulations. The performance of this controller is compared to that of a PID controller. The results show that the proposed method performs better than a well tuned PID controller.

We implemented a NOS and HOS-enriched Problem-Based Learning environment at the middle (year 7 of the Portuguese National Curriculum and secondary level (year 10 for teaching the origins of biodiversity and of continents and oceans (mobilism.  The goal of providing detailed implementation practices is to adress the lack of how to in Problem-based learning (PBL implementation in classrooms for 12 to 16 year old students and is the first practical example of implementation using this episode of HOS for teaching geological mobilism integrated with evolution. Therefore, in this study, we provide specific suggestions for supporting teachers’ classroom efforts in implementing PBL, such as scaffolding. The ill-problem presented to students, without a single correct answer, was based on the phylogeny of extant and extinct ratite birds, described by Charles Darwin and the present geographical distribution. The evaluation of the students was focused on the chain of reasoning employed, and we performed a comparisation analysis of the problem’s solution presented by the students of both classes regarding the explanation of the phylogeny of ratites based on geological mobilism. We observed an overall improvement (25-77% of the percentages of students pre- and post-instruction adequate answers; therefore our PBL strategy was efficient.

    Baccalaureate nursing programs require students to complete a research course, and faculty find it challenging to engage students. Educational gaming has recently gained attention as a technique to motivate students and enhance learning. The purpose of this pilot study was to describe undergraduate nursing students' reflections of their experiences with 3D Gamelab(©), a game-based learning platform. A descriptive qualitative research design was used to elicit students' reflections of their experiences. Educational content such as handouts, videos, activities, and recommended resources for a required junior level nursing research course was organized into quests for use in 3D GameLab(©). At the end of the semester, students were invited to give their feedback through a survey with open-ended questions. Thematic analysis resulted in the following components of the game-based learning experience: navigation, motivation, gaming concept, knowledge, technology, and target population. Although the overall response to 3D GameLab(©) in this course was negative, game-based learning does have the potential to engage students and enhance learning. To better understand how educational gaming could be used in nursing, further research should be conducted to determine the most motivating elements and the types of course content best delivered in this manner.

    Full Text Available Several emerging issues concerning the development of interactive learning environment were left unsolved although e-learning has been applied for years. With several studies indicate that more interaction between students and systems increases students’ level of interest and allows them to focus on learning support. Due to the way current interactive learning tools are designed, users have to wear or operate actual tools in order to carry out the required learning procedures. The use of tools for long durations of time results in user fatigue. Hence, this study incorporates the Microsoft Kinect as interactive tool for detecting gestures in the e-learning process. This study also uses the interaction method that we had developed on Facebook to interact with the proposed learning system. The experiments in this study are divided into five parts: system performance of the 3D web engine, gesture accuracy, system and gesture usability, system and gesture satisfaction, and learning satisfaction of the learner. Also, the gesture design was accepted by learners when they interacted with the learning system. Our research shows that our concept as well as the features of our system can fully support social learning and enhance interaction between users in learning environments.

    Although process elements that define community-based participatory research (CBPR) are well articulated and provide guidance for bringing together researchers and communities, additional models to implement CBPR are needed. One potential model for implementing and monitoring CBPR is Action Learning Collaboratives (ALCs); short term, team-based learning processes that are grounded in quality improvement. Since 2010, the Prevention Research Center at Dartmouth (PRCD) has used ALCs with three communities as a platform to design, implement and evaluate CBPR. The first ALC provided an opportunity for academia and community leadership to strengthen their relationships and knowledge of respective assets through design and evaluation of community-based QI projects. Building on this work, we jointly designed and are implementing a second ALC, a cross-community research project focused on obesity prevention in vulnerable populations. An enhanced community capacity now exists to support CBPR activities with a high degree of sophistication and decreased reliance on external facilitation.

    Essential tremor (ET) is a highly prevalent movement disorder. Patients with ET exhibit a complex progressive and disabling tremor, and medical management often fails. Deep brain stimulation (DBS) has been successfully applied to this disorder, however there has been no quantifiable way to measure tremor severity or treatment efficacy in this patient population. The quantified amelioration of kinetic tremor via DBS is herein demonstrated through the application of a smartphone (iPhone) as a wireless accelerometer platform. The recorded acceleration signal can be obtained at a setting of the subject's convenience and conveyed by wireless transmission through the Internet for post-processing anywhere in the world. Further post-processing of the acceleration signal can be classified through a machine learning application, such as the support vector machine. Preliminary application of deep brain stimulation with a smartphone for acquisition of a feature set and machine learning for classification has been successfully applied. The support vector machine achieved 100% classification between deep brain stimulation in `on' and `off' mode based on the recording of an accelerometer signal through a smartphone as a wireless accelerometer platform.

  16. Development of a Chip/Chip/SRM platform using digital chip isoelectric focusing and LC-Chip mass spectrometry for enrichment and quantitation of low abundance protein biomarkers in human plasma.

    Protein biomarkers are critical for diagnosis, prognosis, and treatment of disease. The transition from protein biomarker discovery to verification can be a rate limiting step in clinical development of new diagnostics. Liquid chromatography-selected reaction monitoring mass spectrometry (LC-SRM MS) is becoming an important tool for biomarker verification studies in highly complex biological samples. Analyte enrichment or sample fractionation is often necessary to reduce sample complexity and improve sensitivity of SRM for quantitation of clinically relevant biomarker candidates present at the low ng/mL range in blood. In this paper, we describe an alternative method for sample preparation for LC-SRM MS, which does not rely on availability of antibodies. This new platform is based on selective enrichment of proteotypic peptides from complex biological peptide mixtures via isoelectric focusing (IEF) on a digital ProteomeChip (dPC) for SRM quantitation using a triple quadrupole (QQQ) instrument with an LC-Chip (Chip/Chip/SRM). To demonstrate the value of this approach, the optimization of the Chip/Chip/SRM platform was performed using prostate specific antigen (PSA) added to female plasma as a model system. The combination of immunodepletion of albumin and IgG with peptide fractionation on the dPC, followed by SRM analysis, resulted in a limit of quantitation of PSA added to female plasma at the level of ∼1-2.5 ng/mL with a CV of ∼13%. The optimized platform was applied to measure levels of PSA in plasma of a small cohort of male patients with prostate cancer (PCa) and healthy matched controls with concentrations ranging from 1.5 to 25 ng/mL. A good correlation (r(2) = 0.9459) was observed between standard clinical ELISA tests and the SRM-based assay. Our data demonstrate that the combination of IEF on the dPC and SRM (Chip/Chip/SRM) can be successfully applied for verification of low abundance protein biomarkers in complex samples.

    2014-01-01

    The Lower Saxony Research Network "Design of Environments for Ageing" (GAL) studied possible applications of assistive technology for enabling older adults to live longer and independent in their own home. As part of this work, a technical platform was developed as a common technical basis for all assistive systems in the project. This article presents an overview of the architecture and core functionality of the technical platform, which in the first generation was developed for use in a laboratory setting, and in a second generation was extended for use in the project's field studies, i.e. prototype installations in end-users homes. The field studies' primary objective was the evaluation of the assistive technologies, that were developed within the overall project. However, these studies also confirmed that the fundamental concept of the technical platform is valid, and the prototypes continuously worked 24 h a day for several months. However, there were some problems related to lack of infrastructure in the older adults' homes and human factors such as inadvertent placement of objects across sensors' field of view, acceptance problems due to aesthetical reasons or simply communication problems, which show that making complex technologies work for users with little technical experience is well possible, but requires a careful consideration of the complete service chain and related "soft factors".

  12. Platforms, Communities, and Business Ecosystems: Lessons Learned about Technology Entrepreneurship in an Interconnected World

    Directory of Open Access Journals (Sweden)

    Steven Muegge

    2013-02-01

    Full Text Available Technology entrepreneurs are increasingly building businesses that are deliberately anchored in platforms, communities, and business ecosystems. Nonetheless, actionable, evidence-based advice for technology entrepreneurs is scarce. Platforms, communities, and ecosystems are active areas of management research, but until recently, each has been studied in separate research programs, with results published in different venues, and often examined from the perspectives of incumbent managers or policy makers rather than entrepreneurs and new entrants. This article re-examines these phenomena from the perspective of technology entrepreneurs facing strategic choices about interconnected systems of platforms, communities, and business ecosystems, and decisions about the nature and extent of participation. It brings together insights from a wide range of published sources. For entrepreneurs, it provides an accessible introduction to what can be a complex topic, identifies a set of practical considerations to be accounted for in decision-making, and offers a guide for further reading. For researchers and graduate students seeking practical and high-impact research problems, it provides an entry point to the research literature and identifies gaps in the current body of knowledge, especially regarding the system-level interactions between subsystems.

The research examines (1 the effectiveness of IBDL for regular and distance students and (2 the distance students’ experience of VClass in the IBDL course entitled Computer Programming 1. The study employed the common definitions of evaluation to attain useful statistical results. The measurement instruments used were test scores and questionnaires. The sample consisted of 59 first-year undergraduate students, most of whom were studying computer information systems at Rajamangala University of Technology Lanna Chiang Mai in Thailand. The results revealed that distance students engaged in learning behavior only occasionally but that the effectiveness of learning was the same for distance and regular students. Moreover, the provided computer-mediated communications (CMC (e.g., live chat, email, and discussion board were sparingly used, primarily by male distance students. Distance students, regular students, the instructor, and the tutor agreed to use a social networking site, Facebook, rather than the provided CMC during the course. The evaluation results produce useful information that is applicable for developing and improving IBDL practices.

  19. Towards a Standard-based Domain-specific Platform to Solve Machine Learning-based Problems

    Directory of Open Access Journals (Sweden)

    Vicente García-Díaz

    2015-12-01

    Full Text Available Machine learning is one of the most important subfields of computer science and can be used to solve a variety of interesting artificial intelligence problems. There are different languages, framework and tools to define the data needed to solve machine learning-based problems. However, there is a great number of very diverse alternatives which makes it difficult the intercommunication, portability and re-usability of the definitions, designs or algorithms that any developer may create. In this paper, we take the first step towards a language and a development environment independent of the underlying technologies, allowing developers to design solutions to solve machine learning-based problems in a simple and fast way, automatically generating code for other technologies. That can be considered a transparent bridge among current technologies. We rely on Model-Driven Engineering approach, focusing on the creation of models to abstract the definition of artifacts from the underlying technologies.

    The usability analysis of information systems has been the target of several research studies over the past thirty years. These studies have highlighted a great diversity of points of view, including researchers from different scientific areas such as Ergonomics, Computer Science, Design and Education. Within the domain of information ergonomics, the study of tools and methods used for usability evaluation dedicated to E-learning presents evidence that there is a continuous and dynamic evolution of E-learning systems, in many different contexts -academics and corporative. These systems, also known as LMS (Learning Management Systems), can be classified according to their educational goals and their technological features. However, in these systems the usability issues are related with the relationship/interactions between user and system in the user's context. This review is a synthesis of research project about Information Ergonomics and embraces three dimensions, namely the methods, models and frameworks that have been applied to evaluate LMS. The study also includes the main usability criteria and heuristics used. The obtained results show a notorious change in the paradigms of usability, with which it will be possible to discuss about the studies carried out by different researchers that were focused on usability ergonomic principles aimed at E-learning.

    The aim of this study is to evaluate the many practical formats that support the first-year veterinary curriculum. These practical classes are diverse in content and style. They include laboratory-based formats, classes involving live animals and cadavers, classes conducted using computer-aided learning tools, study groups, and information technology training. This preliminary study examines ratings for these practical classes, but also relates these ratings to students' approaches to study with the aim of understanding how a deep learning approach manifests itself in the practical setting. The diverse behaviors and attitudes to practical classes are also evaluated in the light of the approaches to study. A questionnaire that evaluated (1) a total of 24 practical classes, (2) the 52-item Approaches to Study Inventory, and (3) 13 behaviors within and attitudes to practical classes was distributed to 69 first-year veterinary students in their final term. Practical classes that involved live animals and cadavers were rated most positively by this group of students. These ratings, however, did not correlate significantly with the deep or surface learning score. The majority of practical classes where the ratings were found to be associated with deep and surface learning were laboratory-based, although overall these practical classes tended to be rated lower than those involving animals. Ratings did not correlate significantly with the strategic approach. A number of behaviors and attitudes to practical classes were also found to be positively and significantly (p=0.0001) associated with the deep learning approach. This preliminary study indicates that this cohort of veterinary students has an overall positive perception of practical classes that permit contact with live animals or cadavers. Although the perception of laboratory-type practical classes was lower overall, the ratings for these practical classes appeared to be influenced by their deep and surface learning

    The companies that are working in decontamination, dismantling and assessment in nuclear power plants, usually have their employees in different facilities far from its central offices. When there is a training in radiological protection applied to the nuclear field, it is difficult for these people the attendance to the course because of different reasons as the location of the formation centres which sometimes are not near from the nuclear facilities, so they usually cannot attend their daily work with the same effectiveness. In this work we present a postgraduate training in radiological protection supervised by Polytechnical University of Valencia (Spain) applied to nuclear and radioactive facilities by a technological platform developed in collaboration with the university. This platform is adapted and designed to different high level contents and applications in different areas and sections, related to a general part, radioactive facilities, nuclear facilities and advanced concepts. When the student finishes an area, an evaluation has to be done to prove the understanding of the lessons. We have included films of different activities as decontamination devices, radiation detectors..etc with the contents to make the explanations more understandable to the student. The course is complemented with a final review and exam that are not online to guarantee that the training is well finished. In addition the student has some practice related with different items explained during the training as the use of equipment in radiological protection tasks. This type of training is more flexitime and can be adapted to the necessities of each user, avoiding high costs and unnecessary displacements. (author)

    Full Text Available We present results of our machine learning approach to the problem of classifying GC-MS data originating from wheat grains of different farming systems. The aim is to investigate the potential of learning algorithms to classify GC-MS data to be either from conventionally grown or from organically grown samples and considering different cultivars. The motivation of our work is rather obvious on the background of nowadays increased demand for organic food in post-industrialized societies and the necessity to prove organic food authenticity. The background of our data set is given by up to eleven wheat cultivars that have been cultivated in both farming systems, organic and conventional, throughout three years. More than 300 GC-MS measurements were recorded and subsequently processed and analyzed in the MeltDB 2.0 metabolomics analysis platform, being briefly outlined in this paper. We further describe how unsupervised (t-SNE, PCA and supervised (RF, SVM methods can be applied for sample visualization and classification. Our results clearly show that years have most and wheat cultivars have second-most influence on the metabolic composition of a sample. We can also show, that for a given year and cultivar, organic and conventional cultivation can be distinguished by machine-learning algorithms.

    The need for reform in nursing education has been clearly defined.The difficulty has been in finding ways to facilitate the process. This article describes an innovative web-based virtual community, The Neighborhood, used to promote conceptual learning across a new curriculum at the University of New Mexico College of Nursing. The Neighborhood features 30 fictional characters that represent various cultural and socioeconomic backgrounds and demonstrate a range of health and psychosocial prob-lems. These characters interact with various community agencies in numerous health care settings. The Neighborhood has strong links to three well-founded teaching strategies: storytelling, case-based learning, and interpretive pedagogy. Because the cases unfold over time, in much the same way problems develop in real life, ongoing exposure to a concept is permitted, facilitating deep understanding.

    Adaptive learning platforms (ALPs) can revolutionize medical education by making learning more efficient, but their potential has not been realized because students do not use them persistently. We applied educational data mining methods to study United States medical students who used an ALP called Osmosis ( www.osmosis.org ) from 1 August 2014 to 31 July 2015. Multivariate logistic regressions modeled persistence on Osmosis as the dependent variable and Osmosis-collected variables as predictors. The 6787 students included in our analysis responded to a total of 887,193 items, with 2138 (31.5%) using Osmosis persistently. Number of items per student, mobile device use, subscription payment, and group membership were independently associated with persisting (p < 0.001 in all models). Persistent users rated quality more favorably (p < 0.01) but were not more confident in answer selections (p = 0.80). While persisters were more accurate than non-persisters (55% (SD 18%) vs 52% (SD 22%), p < 0.001), after adjusting for number of items, lower accuracy was associated with persistent use (OR 0.93 [95% CI 0.90-0.97], p < 0.01). Our study of a large sample of U.S. medical students illustrates big data medical education research and provides guidance for improving implementation of ALPs and further investigation.

    The chemical composition of propolis is affected by environmental factors and harvest season, making it difficult to standardize its extracts for medicinal usage. By detecting a typical chemical profile associated with propolis from a specific production region or season, certain types of propolis may be used to obtain a specific pharmacological activity. In this study, propolis from three agroecological regions (plain, plateau, and highlands) from southern Brazil, collected over the four seasons of 2010, were investigated through a novel NMR-based metabolomics data analysis workflow. Chemometrics and machine learning algorithms (PLS-DA and RF), including methods to estimate variable importance in classification, were used in this study. The machine learning and feature selection methods permitted construction of models for propolis sample classification with high accuracy (>75%, reaching ∼90% in the best case), better discriminating samples regarding their collection seasons comparatively to the harvest regions. PLS-DA and RF allowed the identification of biomarkers for sample discrimination, expanding the set of discriminating features and adding relevant information for the identification of the class-determining metabolites. The NMR-based metabolomics analytical platform, coupled to bioinformatic tools, allowed characterization and classification of Brazilian propolis samples regarding the metabolite signature of important compounds, i.e., chemical fingerprint, harvest seasons, and production regions.

  18. Developing a Platform for Learning from Mistakes: changing the culture of patient safety amongst junior doctors.

    Junior doctors commonly make mistakes which may compromise patient safety. Despite the recent push by the NHS to encourage a "no blame" culture, mistakes are still viewed as shameful, embarrassing and demoralising events. The current model for learning from mistakes means that junior doctors only learn from their own errors. A survey was designed by the author for all the Foundation Year 1 doctors (FY1s) at Yeovil District Hospital to understand better the culture surrounding mistakes, and the types of mistakes that were being made. Using the results of the survey and the support of senior staff, a "Near misses" session has been introduced for FY1s once a month at which mistakes that have been made are discussed, with a consultant present to facilitate the proceedings. The aims of these sessions are to promote a culture of no blame, feedback information to clinical governance, and share learning experiences. 100% of the FY1s had made a mistake that could compromise patient safety. 63% discussed their mistakes with colleagues, 44% with seniors, and only 13% with their educational supervisor. Barriers to discussing mistakes included shame, embarrassment, fear of judgement, and unapproachable seniors. 94% thought a "Near misses" session would be useful. After the third session 100% of the FY1s agreed that the sessions were useful; 53% had changed their practice as a result of something they learned at the sessions. After discussing errors as a group we have worked with the clinical governance department, enacting strategies to avoid repetition of mistakes. Feedback from the junior doctors has been overwhelmingly positive and we have found these sessions to be a simple, inexpensive, and popular solution to cultural change in our organisation.

    In traffic engineering, vehicle detectors are trained on limited datasets, resulting in poor accuracy when deployed in real-world surveillance applications. Annotating large-scale high-quality datasets is challenging. Typically, these datasets have limited diversity; they do not reflect the real-world operating environment. There is a need for a large-scale, cloud-based positive and negative mining process and a large-scale learning and evaluation system for the application of automatic traffic measurements and classification. The proposed positive and negative mining process addresses the quality of crowd sourced ground truth data through machine learning review and human feedback mechanisms. The proposed learning and evaluation system uses a distributed cloud computing framework to handle data-scaling issues associated with large numbers of samples and a high-dimensional feature space. The system is trained using AdaBoost on 1,000,000 Haar-like features extracted from 70,000 annotated video frames. The trained real-time vehicle detector achieves an accuracy of at least 95% for 1/2 and about 78% for 19/20 of the time when tested on ˜7,500,000 video frames. At the end of 2016, the dataset is expected to have over 1 billion annotated video frames.

    The combination of point-of-care (POC) medical microdevices and machine learning has the potential transform the practice of medicine. In this area, scalable lab-on-a-chip (LOC) devices have many advantages over standard laboratory methods, including faster analysis, reduced cost, lower power consumption, and higher levels of integration and automation. Despite significant advances in LOC technologies over the years, several remaining obstacles are preventing clinical implementation and market penetration of these novel medical microdevices. Similarly, while machine learning has seen explosive growth in recent years and promises to shift the practice of medicine toward data-intensive and evidence-based decision making, its uptake has been hindered due to the lack of integration between clinical measurements and disease determinations. In this Account, we describe recent developments in the programmable bio-nanochip (p-BNC) system, a biosensor platform with the capacity for learning. The p-BNC is a "platform to digitize biology" in which small quantities of patient sample generate immunofluorescent signal on agarose bead sensors that is optically extracted and converted to antigen concentrations. The platform comprises disposable microfluidic cartridges, a portable analyzer, automated data analysis software, and intuitive mobile health interfaces. The single-use cartridges are fully integrated, self-contained microfluidic devices containing aqueous buffers conveniently embedded for POC use. A novel fluid delivery method was developed to provide accurate and repeatable flow rates via actuation of the cartridge's blister packs. A portable analyzer instrument was designed to integrate fluid delivery, optical detection, image analysis, and user interface, representing a universal system for acquiring, processing, and managing clinical data while overcoming many of the challenges facing the widespread clinical adoption of LOC technologies. We demonstrate the p

    Aging weakens memory functions. Exposing healthy rodents or pathological rodent models to environmental enrichment (EE) housing improves their cognitive functions by changing neuronal levels of excitation, cellular signaling, and plasticity, notably in the hippocampus. At the molecular level, brain derived-neurotrophic factor (BDNF) represents an important player that supports EE-associated changes. EE facilitation of learning was also shown to correlate with chromatin acetylation in the hippocampus. It is not known, however, whether such mechanisms are still into play during aging. In this study, we exposed a cohort of aged rats (18-month-old) to either a 6 month period of EE or standard housing conditions and investigated chromatin acetylation-associated events [histone acetyltranferase activity, gene expression, and histone 3 (H3) acetylation] and epigenetic modulation of the Bdnf gene under rest conditions and during learning. We show that EE leads to upregulation of acetylation-dependent mechanisms in aged rats, whether at rest or following a learning challenge. We found an increased expression of Bdnf through Exon-I-dependent transcription, associated with an enrichment of acetylated H3 at several sites of Bdnf promoter I, more particularly on a proximal nuclear factor κB (NF-κB) site under learning conditions. We further evidenced p65/NF-κB binding to chromatin at promoters of genes important for plasticity and hippocampus-dependent learning (e.g., Bdnf, CamK2D). Altogether, our findings demonstrate that aged rats respond to a belated period of EE by increasing hippocampal plasticity, together with activating sustained acetylation-associated mechanisms recruiting NF-κB and promoting related gene transcription. These responses are likely to trigger beneficial effects associated with EE during aging. Aging weakens memory functions. Optimizing the neuronal circuitry required for normal brain function can be achieved by increasing sensory, motor, and

    Acute care nurse practitioner (ACNP) programs that use high-fidelity simulation as a teaching tool need to consider innovative strategies to provide distance-based students with learning experiences that are comparable to those in a simulation laboratory. The purpose of this article is to describe the use of virtual simulations in a distance-based ACNP program and student performance in the simulations. Virtual simulations using iSimulate were integrated into the ACNP course to promote the translation of content into a clinical context and enable students to develop their knowledge and decision-making skills. With these simulations, students worked as a team, even though they were at different sites from each other and from the faculty, to manage care of an acutely ill patient. The students were assigned to simulation groups of 4 students each. One week before the simulation, they reviewed past medical records. The virtual simulation sessions were recorded and then evaluated. The evaluation tools assessed 8 areas of performance and included key behaviors in each of these areas to be performed by students in the simulation. More than 80% of the student groups performed the key behaviors. Virtual simulations provide a learning platform that allows live interaction between students and faculty, at a distance, and application of content to clinical situations. With simulation, learners have an opportunity to practice assessment and decision-making in emergency and high-risk situations. Simulations not only are valuable for student learning but also provide a nonthreatening environment for staff to practice, receive feedback on their skills, and improve their confidence.

Students seem to like smartphones aswell and a good question is if and to what extend those devices can play a role in e-learning.„Mediman“, an adaptation of the common game Hangman has been developed for smartphones. Test users asked to complete an online questionnaire. So far, only few e-learning applications for smartphones seem to exist. This is reflected in the low usage frequency. Especially the fact that most of the test users wear a smartphone with them all the time makes it an ideal learning plattform. Short learning sessions were rated more important than continuous text. The majority of the 11 test users rated Mediman as well developed. The foremost question whether a smartphone e-learning application is feasible must be answered positive – acceptance in the test user group was shown. E-learning applications on smartphones will be an important topic in the future as market shares increase constantly.

    With the popularity of mobile devices, cloud computing and other new technologies, the information tech-nology ecological changes of primary and secondary schools are taking place. Creating a smart learning environment is the most direct way to embrace the changes. A personalized learning platform is a prerequisite to achieve “smart learning”. The technology of learning analytics based on big data is an important solution to build practical personal-ized learning platform because it provides a blueprint for the realization of personalized learning. In the development stage of learning analytics, the literature survey shows the existing research papers mainly focus on the review and a-nalysis of the application . The typical case is mainly focusing on the dynamic acquisition and analysis of an LMS platform. Related application cases in K-12 education is rare. Meanwhile, due to the complex nature of education it-self, the early"intelligent expert systems" experience has shown that teaching which relies entirely on"expert systems"or a "machine mentor" has its deficiencies. Currently, when we try to construct a personalized learning platform, "smart" and"practicality" is still a pair of mutual support and mutual restraints associated variables, and the focus of our work is to find the balance of them. For this reason, we adopted a dynamic granularity group approach to realize personalization. We can control the degree of personalization learning by the granularity. When the granularity is lar-ger than one,the teaching mode is group learning. Otherwise, the teaching model is individualized learning.%个性化学习平台是实现“智慧学习”的前提,而依托大数据的学习分析技术则是构建实用性强的个性化学习平台的重要保障。然而,目前学习分析技术仍处在发展阶段,相关文献表明现有研究主要集中于理论综述和应用分析,多侧重于基于学习管理系统的数据采集与分析,面向基

Classical repeated measures ANOVA showed that combined EE-EGCG treatment was more efficient than EE or EGCG alone to improve specific spatial learning related variables. Using principal component analysis (PCA we found that several spatial learning parameters contributed similarly to a first PC and explained a large proportion of the variance among groups, thus representing a composite learning measure. This PC1 revealed that EGCG or EE alone had no significant effect. However, combined EE-EGCG significantly ameliorated learning alterations of middle age Ts65Dn mice. Interestingly, PCA revealed an increased variability along learning sessions with good and poor learners in Ts65Dn, and this stratification did not disappear upon treatments. Our results suggest that combining EE and EGCG represents a viable therapeutic approach for amelioration of age-related cognitive decline in DS, although its efficacy may vary across individuals.

    Full Text Available Abstract: This paper covers the design and development of a noncommercial software for learning and practicing English called CyberL@b. It was developed at the School of Modern Languages at the University of Costa Rica. Its target population focuses on 7th, 8th and 9th graders at six public high schools in diverse urban and rural settings in Costa Rica.CyberL@b uses interactive media resources designed to engage student in learning English within authentic contexts.Cyberlab was designed to create an environment that is unique in fostering the integration of the four language skills (listening, speaking, reading, and writing through social interactions that are critical in EFL (English as a Foreign Language. An initial needs analysis of the six schools indicated that students considered the following to be important contributors to language learning: conversations with tourists, computer programs and video games, movies, and email of class notes. The implementation of CyberL@b indicates that when students engage in authentic activities relevant to their needs, they become more autonomous and self-directed in their learning. Teachers also adopt more learnercentered methods in their language teaching. On the basis of ongoing development and evaluation, a variety of approaches and technical strategies have been considered to allow students to engage in real-time authentic language learning activities through CyberL@b.Resumen:Este documento describe el diseño y desarrollo de un software no—comercial para el aprendizaje y aplicación práctica del inglés llamado CyberL@b.

    The Virtual Brain (TVB; thevirtualbrain.org) is a neuroinformatics platform for full brain network simulation based on individual anatomical connectivity data. The framework addresses clinical and neuroscientific questions by simulating multi-scale neural dynamics that range from local population activity to large-scale brain function and related macroscopic signals like electroencephalography and functional magnetic resonance imaging. TVB is equipped with a graphical and a command-line interface to create models that capture the characteristic biological variability to predict the brain activity of individual subjects. To enable researchers from various backgrounds a quick start into TVB and brain network modeling in general, we developed an educational module: TVB-EduPack. EduPack offers two educational functionalities that seamlessly integrate into TVB's graphical user interface (GUI): (i) interactive tutorials introduce GUI elements, guide through the basic mechanics of software usage and develop complex use-case scenarios; animations, videos and textual descriptions transport essential principles of computational neuroscience and brain modeling; (ii) an automatic script generator records model parameters and produces input files for TVB's Python programming interface; thereby, simulation configurations can be exported as scripts that allow flexible customization of the modeling process and self-defined batch- and post-processing applications while benefitting from the full power of the Python language and its toolboxes. This article covers the implementation of TVB-EduPack and its integration into TVB architecture. Like TVB, EduPack is an open source community project that lives from the participation and contribution of its users. TVB-EduPack can be obtained as part of TVB from thevirtualbrain.org.

    Full Text Available Abstract Background In the last decade, sequencing projects have led to the development of a number of annotation systems dedicated to the structural and functional annotation of protein-coding genes. These annotation systems manage the annotation of the non-protein coding genes (ncRNAs in a very crude way, allowing neither the edition of the secondary structures nor the clustering of ncRNA genes into families which are crucial for appropriate annotation of these molecules. Results LeARN is a flexible software package which handles the complete process of ncRNA annotation by integrating the layers of automatic detection and human curation. Conclusion This software provides the infrastructure to deal properly with ncRNAs in the framework of any annotation project. It fills the gap between existing prediction software, that detect independent ncRNA occurrences, and public ncRNA repositories, that do not offer the flexibility and interactivity required for annotation projects. The software is freely available from the download section of the website http://bioinfo.genopole-toulouse.prd.fr/LeARN

    Chinese medical universities typically have a high number of students, a shortage of teachers and limited equipment, and as such histology courses have been taught using traditional lecture-based formats, with textbooks and conventional microscopy. This method, however, has reduced creativity and problem-solving skills training in the curriculum. The virtual microscope (VM) system has been shown to be an effective and efficient educational strategy. The present study aims to describe a VM system for undergraduates and to evaluate the effects of promoting active learning and problem-solving skills. Two hundred and twenty-nine second-year undergraduate students in the Third Military Medical University were divided into two groups. The VM group contained 115 students and was taught using the VM system. The light microscope (LM) group consisted of 114 students and was taught using the LM system. Post-teaching performances were assessed by multiple-choice questions, short essay questions, case analysis questions and the identification of structure of tissue. Students' teaching preferences and satisfaction were assessed using questionnaires. Test scores in the VM group showed a significant improvement compared with those in the LM group (p 0.05); however, there were notable differences in the mean score rate of case analysis questions and identification of structure of tissue (p platform.

    2016-02-01

    In this paper, a self-recurrent wavelet neural network (SRWNN)-based indirect adaptive control architecture is modified for performing speed control of a motion platform. The transient behaviour of the original learning algorithm has been improved by modifying the learning rate updates. The contribution of the proposed modification has been verified via both simulations and experiments. Moreover, the performance of the proposed architecture is compared with robust RST designs performed on a similar benchmark system, to show that via adaptive nonlinear control, it is possible to obtain a fast step response without degrading the robustness of a multi-body mechanical system. Finally, the architecture is further improved so as to possess structural learning for populating the SRWNNs automatically, rather than employing static network structures, and simulation results are provided to show the performance of the proposed structural learning algorithm.

    Linguistics, psychology, and neuroscience all have rich histories in language research. Crosstalk among these disciplines, as realized in studies of phonology, is pivotal for understanding a fundamental challenge for first and second language learners (SLLs): learning verbs. Linguistic and behavioral research with monolinguals suggests that infants attend to foundational event components (e.g., path, manner). Language then heightens or dampens attention to these components as children map word to world in language-specific ways. Cross-linguistic differences in semantic organization also reveal sources of struggles for SLLs. We discuss how better integrating neuroscience into this literature can unlock additional mysteries of verb learning.

    E-learning is playing an increasing role in medical education, supporting a problem-based and practical oriented education without putting patients at risk and compensating for the decrease in instructor-centered teaching. Not much research has been done concerning learning effects and reaction on behalf of the students. We created computer-based cases for four important diagnoses in urology using the authoring system CASUS®. Fourth-year medical school students were randomized into two groups: (1) the CASUS® group, using the online cases for preparation, and (2) the book group, using a textbook. A multiple-choice test referring to the prepared topic had to be completed at the beginning of each lecture and the results were analyzed. Evaluation of the students concerning the acceptance of the program was done at the end of the semester. Members of the CASUS® group scored significantly higher with an average of 20% better test results than students using textbooks for preparation. Evaluation regarding the program showed a highly positive rating. Limitations include the small study population and the possibly biased test performance of the students. Computerized patient cases facilitate practice-oriented teaching and result in an interesting and engaging learning model with improved learning outcomes. © 2015 S. Karger AG, Basel.

    Despite the role afforded interoceptive fear conditioning in etiologic accounts of panic disorder, there are no good experimental demonstrations of such learning in humans. The aim of the present study was to evaluate the interoceptive conditioning account using 20% carbon dioxide (CO(2))-enriched air as an interoceptive conditioned stimulus (CS) (i.e., physiologically inert 5-s exposures) and unconditioned stimulus (US) (i.e., physiologically prepotent 15-s exposures). Healthy participants (N=42) were randomly assigned to one of three conditions: a CS-only, contingent CS-US pairings, or unpaired/non-contingent CS and US presentations. Electrodermal and self-report (e.g., distress, fear) served as indices of conditioned emotional responding. Results showed greater magnitude electrodermal and evaluative fear conditioning in the paired relative to the CS-only condition. The explicitly unpaired condition showed even greater electrodermal and evaluative responding during acquisition, and marked resistance to extinction. The latter results are consistent with the possibility that the unpaired procedure constituted a partial reinforcement procedure in which CO(2) onset was paired with more extended CO(2) exposure on 50% of the trials. Overall, the findings are consistent with contemporary learning theory accounts of panic.

    Epidemiological studies suggest that individuals with greater education or more cognitively demanding occupations have diminished risk of developing dementia. We wanted to test whether this effect could be recapitulated in rodents using environmental enrichment, a paradigm well documented to attenuate behavioral deficits induced by various pathological insults. Here, we demonstrate that learning and memory deficits observed in a transgenic mouse model of Alzheimer's disease can be ameliorated by enrichment. Female transgenic mice overexpressing amyloid precursor protein and/or presenilin-1 and nontransgenic controls were placed into enriched or standard cages at 2 months of age and tested for cognitive behavior after 6 months of differential housing. Enrichment significantly improved performance of all genotypes in the radial water maze and in the classic and repeated-reversal versions of the Morris water maze. However, enrichment did not benefit all genotypes equally. Mice overproducing amyloid-beta (Abeta), particularly those with amyloid deposits, showed weaker memory for the platform location in the classic Morris water maze and learned new platform positions in the repeated-reversals task less quickly than their nontransgenic cagemates. Nonetheless, enrichment normalized the performance of Abeta-overproducing mice to the level of standard-housed nontransgenic mice. Moreover, this functional preservation occurred despite increased neuritic plaque burden in the hippocampus of double-transgenic animals and elevated steady-state Abeta levels, because both endogenous and transgene-derived Abeta are increased in enriched animals. These results demonstrate that the generation of Abeta in vivo and its impact on the function of the nervous system can be strongly modulated by environmental factors.

    substantially differ in the knowledge background, network environment and learning needs. Besides, they have low learning participation and too much randomness of learning behavior. According to the statistics in this study, after learning materials have been published, the average resource conversion rate is less than 27% in the first seven days. Furthermore, only 9. 53% of users are giving feedback on questions or evaluations, and 11. 7% of users are choosing to drop out by the end of this study. Because of the technical limitations, the users won't be allowed to make conversation with other users by the WeChat public platform if they need help from peers. The WeChat public platform can only provide the conditions to have communication between the users and the managers.

    Continuous environmental stimulation induced by exposure to enriched environment (EE) has yielded cognitive benefits in different models of brain injury. Perinatal asphyxia results from a lack of oxygen supply to the fetus and is associated with long-lasting neurological deficits. However, the effects of EE in middle-aged rats suffering perinatal asphyxia are unknown. Therefore, the aim of the present study was to assess whether life-long exposure to EE could counteract the cognitive and behavioral alterations in middle-aged asphyctic rats. Experimental groups consisted of rats born vaginally (CTL), by cesarean section (C+), or by C+ following 19 min of asphyxia at birth (PA). At weaning, rats were assigned to standard (SE) or enriched environment (EE) for 18 months. During the last month of housing, animals were submitted to a behavioral test battery including Elevated Plus Maze, Open Field, Novel Object Recognition and Morris water maze (MWM). Results showed that middle-aged asphyctic rats, reared in SE, exhibited an impaired performance in the spatial reference and working memory versions of the MWM. EE was able to counteract these cognitive impairments. Moreover, EE improved the spatial learning performance of middle-aged CTL and C+ rats. On the other hand, all groups reared in SE did not differ in locomotor activity and anxiety levels, while EE reduced locomotion and anxiety, regardless of birth condition. Recognition memory was altered neither by birth condition nor by housing environment. These results support the importance of environmental stimulation across the lifespan to prevent cognitive deficits induced by perinatal asphyxia.

  2. Designing next-generation platforms for evaluating scientific output: What scientists can learn from the social web

    Directory of Open Access Journals (Sweden)

    Tal eYarkoni

    2012-10-01

    Full Text Available Traditional pre-publication peer review of scientific output is a slow, inefficient, and unreliable process. Efforts to replace or supplement traditional evaluation models with open evaluation platforms that leverage advances in information technology are slowly gaining traction, but remain in the early stages of design and implementation. Here I discuss a number of considerations relevant to the development of such platforms. I focus particular attention on three core elements that next-generation evaluation platforms should strive to emphasize, including (a open and transparent access to accumulated evaluation data, (b personalized and highly customizable performance metrics, and (c appropriate short-term incentivization of the userbase. Because all of these elements have already been successfully implemented on a large scale in hundreds of existing social web applications, I argue that development of new scientific evaluation platforms should proceed largely by adapting existing techniques rather than engineering entirely new evaluation mechanisms. Successful implementation of open evaluation platforms has the potential to substantially advance both the pace and the quality of scientific publication and evaluation, and the scientific community has a vested interest in shifting towards such models as soon as possible.

    Full Text Available One of the main activities of the International Institute of Sociology of Law (IISL is its International Master’s program in Sociology of Law. This program is highly innovative, in that rather than having any in-house teachers, the program is delivered by leading scholars from around the world. In 2014, the IISL celebrated its 25th anniversary, which provided an ideal opportunity to reflect upon the Master’s program. Teachers were invited to provide their views on teaching at the IISL, and the strongest theme that emerged was student diversity. This paper considers why student diversity struck teachers so strongly, and how has the IISL achieved such a highly diverse student body.It then explores teachers’ perceptions of diversity, revealing responses ranging from seeing diversity as a barrier to embracing diversity as enriching for students and teachers alike. Teaching was largely conceived as a form of ‘engaged pedagogy’ (hooks 1994, which involved drawing on a genuine dialogue with students, embracing multiple perspectives, challenging that challenge hegemonic understandings of sociology of law, and interaction beyond the classroom walls. We argue that this model of teaching produces a global community of cosmopolitan, reflective, self-aware, critical, culturally sensitive and caring sociology of law scholars. Una de las actividades principales del Instituto Internacional de Sociología Jurídica (IISJ es su programa de Master Internacional en Sociología Jurídica.

    Over the past decade, analytical approaches based on vibrational spectroscopy, hyperspectral/multispectral imagining and biomimetic sensors started gaining popularity as rapid and efficient methods for assessing food quality, safety and authentication; as a sensible alternative to the expensive and time-consuming conventional microbiological techniques. Due to the multi-dimensional nature of the data generated from such analyses, the output needs to be coupled with a suitable statistical approach or machine-learning algorithms before the results can be interpreted. Choosing the optimum pattern recognition or machine learning approach for a given analytical platform is often challenging and involves a comparative analysis between various algorithms in order to achieve the best possible prediction accuracy. In this work, "MeatReg", a web-based application is presented, able to automate the procedure of identifying the best machine learning method for comparing data from several analytical techniques, to predict the counts of microorganisms responsible of meat spoilage regardless of the packaging system applied. In particularly up to 7 regression methods were applied and these are ordinary least squares regression, stepwise linear regression, partial least square regression, principal component regression, support vector regression, random forest and k-nearest neighbours. MeatReg" was tested with minced beef samples stored under aerobic and modified atmosphere packaging and analysed with electronic nose, HPLC, FT-IR, GC-MS and Multispectral imaging instrument. Population of total viable count, lactic acid bacteria, pseudomonads, Enterobacteriaceae and B. thermosphacta, were predicted. As a result, recommendations of which analytical platforms are suitable to predict each type of bacteria and which machine learning methods to use in each case were obtained.

    2009-11-01

    Automated high-content screening and analysis (HCS/HCA) technology solutions have become indispensable in expediting the pace of drug discovery. Because of the complexity involved in designing, building, and validating HCS/HCA platforms, it is important to design, build, and validate a HCS/HCA platform before it is actually needed. Managed properly, collaboration between technology providers and end users in research is essential in accelerating development of the hardware and software of new HCS/HCA platforms before they become commercially available. Such a collaboration results in the cost effective creation of new technologies that meet specific and customized industrial requirements. This review outlines the history of, and considerations relevant to, the development of the Cytometrix Profiling System by Cytokinetics, Inc. and the "Complete Imaging Solution" for high-content screening, developed by Molecular Devices Corporation (MDC) (now MDS Analytical Technologies), from original conception and testing of various components, to multiple development cycles from 1998 to the present, and finally to market consolidation.

    Background Brief motivational interviewing (MI) can contribute to reductions in morbidity and mortality related to coronary artery disease, through health behavior change. Brief MI, unlike more intensive interventions, was proposed to meet the needs of clinicians with little spare time. While the provision of face-to-face brief MI training on a large scale is complicated, Web-based e-learning is promising because of the flexibility it offers. Objective The primary objective of this pilot study was to examine the feasibility and acceptability of a Web-based e-learning platform for brief MI (MOTIV@CŒUR), which was evaluated by nurses in cardiovascular care. The secondary objective was to assess the preliminary effect of the training on nurses’ perceived brief MI skills and self-reported clinical use of brief MI. Methods We conducted a single-group, pre-post pilot study involving nurses working in a coronary care unit to evaluate MOTIV@CŒUR, which is a Web-based e-learning platform for brief MI, consisting of two sessions lasting 30 and 20 minutes. MOTIV@CŒUR covers 4 real-life clinical situations through role-modeling videos showing nurse-client interactions. A brief introduction to MI is followed by role playing, during which a nurse practitioner evaluates clients’ motivation to change and intervenes according to the principles of brief MI. The clinical situations target smoking, medication adherence, physical activity, and diet. Nurses were asked to complete both Web-based training sessions asynchronously within 20 days, which allowed assessment of the feasibility of the intervention. Data regarding acceptability and preliminary effects (perceived skills in brief MI, and self-reported clinical use of conviction and confidence interventions) were self-assessed through Web-based questionnaires 30 days (±5 days) after the first session. Results We enrolled 27 women and 4 men (mean age 37, SD 9 years) in March 2016. Of the 31 participants, 24 (77%, 95% CI 63%

    Full Text Available Since its identification in 1983, HIV-1 has been the focus of a research effort unprecedented in scope and difficulty, whose ultimate goals--a cure and a vaccine--remain elusive. One of the fundamental challenges in accomplishing these goals is the tremendous genetic variability of the virus, with some genes differing at as many as 40% of nucleotide positions among circulating strains. Because of this, the genetic bases of many viral phenotypes, most notably the susceptibility to neutralization by a particular antibody, are difficult to identify computationally. Drawing upon open-source general-purpose machine learning algorithms and libraries, we have developed a software package IDEPI (IDentify EPItopes for learning genotype-to-phenotype predictive models from sequences with known phenotypes. IDEPI can apply learned models to classify sequences of unknown phenotypes, and also identify specific sequence features which contribute to a particular phenotype. We demonstrate that IDEPI achieves performance similar to or better than that of previously published approaches on four well-studied problems: finding the epitopes of broadly neutralizing antibodies (bNab, determining coreceptor tropism of the virus, identifying compartment-specific genetic signatures of the virus, and deducing drug-resistance associated mutations.

    LeMoyne, Robert; Mastroianni, Timothy

    2016-08-01

    Natural gait consists of synchronous and rhythmic patterns for both the lower and upper limb. People with hemiplegia can experience reduced arm swing, which can negatively impact the quality of gait. Wearable and wireless sensors, such as through a smartphone, have demonstrated the ability to quantify various features of gait. With a software application the smartphone (iPhone) can function as a wireless gyroscope platform capable of conveying a gyroscope signal recording as an email attachment by wireless connectivity to the Internet. The gyroscope signal recordings of the affected hemiplegic arm with reduced arm swing arm and the unaffected arm are post-processed into a feature set for machine learning. Using a multilayer perceptron neural network a considerable degree of classification accuracy is attained to distinguish between the affected hemiplegic arm with reduced arm swing arm and the unaffected arm.

    Energy Technology Data Exchange (ETDEWEB)

    Roser, R. [NRG Technologies, Inc., Reno, NV (United States)

    1998-08-01

    NRG Technologies, Inc. is attempting to develop hardware and infrastructure that will allow mixtures of hydrogen and conventional fuels to become viable alternatives to conventional fuels alone. This commercialization can be successful if the authors are able to achieve exhaust emission levels of less than 0.03 g/kw-hr NOx and CO; and 0.15 g/kw-hr NMHC at full engine power without the use of exhaust catalysts. The major barriers to achieving these goals are that the lean burn regimes required to meet exhaust emissions goals reduce engine output substantially and tend to exhibit higher-than-normal total hydrocarbon emissions. Also, hydrogen addition to conventional fuels increases fuel cost, and reduces both vehicle range and engine output power. Maintaining low emissions during transient driving cycles has not been demonstrated. A three year test plan has been developed to perform the investigations into the issues described above. During this initial year of funding research has progressed in the following areas: (a) a cost effective single-cylinder research platform was constructed; (b) exhaust gas speciation was performed to characterize the nature of hydrocarbon emissions from hydrogen-enriched natural gas fuels; (c) three H{sub 2}/CH{sub 4} fuel compositions were analyzed using spark timing and equivalence ratio sweeping procedures and finally; (d) a full size pick-up truck platform was converted to run on HCNG fuels. The testing performed in year one of the three year plan represents a baseline from which to assess options for overcoming the stated barriers to success.

    We present the results from Vision Prize, an online platform for capturing expert opinion on climate risks and solutions. Expert panelists provided their own opinions, and also predicted the views of their scientific colleagues. This approach (Prelec, 2004 Nature) gives new insight into the level of scientific consensus on various issues, which in some cases may be just as important as knowing the majority view. Questions ranged from causal attributions of past events to predictions about future risks and beliefs about possible solutions. Across all topics, we find that our expert participants agree with each other more than they think they do, often in surprising ways. Data collection for the Vision Prize project was run in collaboration with Environmental Research Web (IOP). Panelists were pre-screened to ensure they have relevant expertise and independently collected h-scores provide an approximate measure of research impact of those giving each response. Charity prizes were awarded for exceptional meta-knowledge, according to Prelec's algorithm.

    Full Text Available This qualitative research is part of a learning effort to better understand how serious games are exploited in a science education context. The research team examined this issue by focusing on augmented reality as a technological innovation imbedded on a tablet. Given the current state of knowledge related to serious games and augmented reality, and given the fact that its use in the context of teaching/learning is not extended, this paper focuses on an initial exploration of how a new teaching practice involving a serious game based on an interactive augmented reality solution would impact on students in a physics class. A Design Based Research methodology was applied in a real‑world context within a college‑level physics class. Two conceptual tests containing ten questions on spatial notions regarding electromagnetic fields were administered to two control groups and two groups using the proposed serious game. The latter groups were administrated a game evaluation questionnaire as well. Thematic interpretation of students written responses to the evaluation questionnaire as well as the lessons and observations we derived from the in-class experimentation are provided and discussed in the paper.

  1. Lessons learned in deploying a cloud-based knowledge platform for the Earth Science Information Partners Federation (ESIP)

    Ontologies and semantic technologies are an essential infrastructure component of systems supporting knowledge integration in the Earth Sciences. Numerous earth science ontologies exist, but are hard to discover because they tend to be hosted with the projects that develop them. There are often few quality measures and sparse metadata associated with these ontologies, such as modification dates, versioning, purpose, number of classes, and properties. Projects often develop ontologies for their own needs without considering existing ontology entities or derivations from formal and more basic ontologies. The result is mostly orthogonal ontologies, and ontologies that are not modular enough to reuse in part or adapt for new purposes, in spite of existing, standards for ontology representation. Additional obstacles to sharing and reuse include a lack of maintenance once a project is completed. The obstacles prevent the full exploitation of semantic technologies in a context where they could become needed enablers for service discovery and for matching data with services. To start addressing this gap, we have deployed BioPortal, a mature, domain-independent ontology and semantic service system developed by the National Center for Biomedical Ontologies (NCBO), on the ESIP Testbed under the governance of the ESIP Semantic Web cluster. ESIP provides a forum for a broad-based, distributed community of data and information technology practitioners and stakeholders to coordinate their efforts and develop new ideas for interoperability solutions. The Testbed provides an environment where innovations and best practices can be explored and evaluated. One objective of this deployment is to provide a community platform that would harness the organizational and cyber infrastructure provided by ESIP at minimal costs. Another objective is to host ontology services on a scalable, public cloud and investigate the business case for crowd sourcing of ontology maintenance. We deployed the

    A preliminary audit of orders for computed tomography was performed to evaluate the typical performance of interns ordering radiologic examinations. According to the audit, the interns showed only minimal improvement after 8 months of work experience. The online radiology ordering module (ROM) program included baseline assessment of student performance (part I), online learning with the ROM (part II), and follow-up assessment of performance with simulated ordering with the ROM (part III). A curriculum blueprint determined the content of the ROM program, with an emphasis on practical issues, including provision of logistic information, clinical details, and safety-related information. Appropriate standards were developed by a committee of experts, and detailed scoring systems were devised for assessment. The ROM program was successful in addressing practical issues in a simulated setting. In the part I assessment, the mean score for noting contraindications for contrast media was 24%; this score increased to 59% in the part III assessment (P = .004). Similarly, notification of methicillin-resistant Staphylococcus aureus status and pregnancy status and provision of referring physician contact information improved significantly. The quality of the clinical notes was stable, with good initial scores. Part III testing showed overall improvement, with the mean score increasing from 61% to 76% (P radiology services, and the experience typically afforded to interns does not address this lack of knowledge. The ROM program was a successful intervention that resulted in statistically significant improvements in the quality of radiologic examination orders, particularly with regard to logistic and radiation safety issues.

    2017-01-01

    Full Text Available While carrying out formative assessment activities over social network services (SNS, it has been noted that personalized notifications have a high chance of “the important post getting lost” in the notification feed. In order to highlight this problem, this paper compares within a posttest only quasi-experiment, a total of 104 first year undergraduate students, all of which are prospective ICT teachers, in two groups. A formative assessment system in the ubiquitous learning context is delivered over an SNS in both groups. In the first group, the SNS has been used for the entire assessment task. In the second group, the questions have been delivered and responses were received over mobile phone “SMS” messages, while the SNS was used solely for providing feedback. The cases were compared in terms of voluntary participation rates and academic success. Both response rates and academic success have been significantly higher in the SMS group.

This may indicate a flaw in message design for using social networks as LMS's. Sensible use of push-messages is advised.

  13. PRGPred: A platform for prediction of domains of resistance gene analogue (RGA in Arecaceae developed using machine learning algorithms

    Directory of Open Access Journals (Sweden)

    MATHODIYIL S. MANJULA

    2015-12-01

    Full Text Available Plant disease resistance genes (R-genes are responsible for initiation of defense mechanism against various phytopathogens. The majority of plant R-genes are members of very large multi-gene families, which encode structurally related proteins containing nucleotide binding site domains (NBS and C-terminal leucine rich repeats (LRR. Other classes possess' an extracellular LRR domain, a transmembrane domain and sometimes, an intracellular serine/threonine kinase domain. R-proteins work in pathogen perception and/or the activation of conserved defense signaling networks. In the present study, sequences representing resistance gene analogues (RGAs of coconut, arecanut, oil palm and date palm were collected from NCBI, sorted based on domains and assembled into a database. The sequences were analyzed in PRINTS database to find out the conserved domains and their motifs present in the RGAs. Based on these domains, we have also developed a tool to predict the domains of palm R-genes using various machine learning algorithms. The model files were selected based on the performance of the best classifier in training and testing. All these information is stored and made available in the online ‘PRGpred' database and prediction tool.

  14. Informatics in radiology: evaluation of an e-learning platform for teaching medical students competency in ordering radiologic examinations.

    LENUS (Irish Health Repository)

    Marshall, Nina L

    2011-09-01

    A preliminary audit of orders for computed tomography was performed to evaluate the typical performance of interns ordering radiologic examinations. According to the audit, the interns showed only minimal improvement after 8 months of work experience. The online radiology ordering module (ROM) program included baseline assessment of student performance (part I), online learning with the ROM (part II), and follow-up assessment of performance with simulated ordering with the ROM (part III). A curriculum blueprint determined the content of the ROM program, with an emphasis on practical issues, including provision of logistic information, clinical details, and safety-related information. Appropriate standards were developed by a committee of experts, and detailed scoring systems were devised for assessment. The ROM program was successful in addressing practical issues in a simulated setting. In the part I assessment, the mean score for noting contraindications for contrast media was 24%; this score increased to 59% in the part III assessment (P = .004). Similarly, notification of methicillin-resistant Staphylococcus aureus status and pregnancy status and provision of referring physician contact information improved significantly. The quality of the clinical notes was stable, with good initial scores. Part III testing showed overall improvement, with the mean score increasing from 61% to 76% (P < .0001). In general, medical students lack the core knowledge that is needed for good-quality ordering of radiology services, and the experience typically afforded to interns does not address this lack of knowledge. The ROM program was a successful intervention that resulted in statistically significant improvements in the quality of radiologic examination orders, particularly with regard to logistic and radiation safety issues.

  15. Exercise, but not environmental enrichment, improves learning after kainic acid-induced hippocampal neurodegeneration in association with an increase in brain-derived neurotrophic factor.

    Science.gov (United States)

    Gobbo, O L; O'Mara, S M

    2005-04-15

    Previous studies have suggested that exercise in a running wheel can be neuroprotective, perhaps due to, among others, gene-expression changes after exercise, increases in trophic proteins and/or enhanced cardiovascular responsivity. Here we ask whether physical exercise or environmental enrichment provide protection after brain damage, especially in terms of recovery of cognitive function. To evaluate the neuroprotective effect of these conditions, we used the kainic acid (KA) model of neuronal injury. Systemically-administered KA induces excitotoxicity by overstimulation of glutamate receptors, resulting in neuronal death by necrosis and apoptosis. Our results show that exercise, but not enriched environment, prior to KA-induced brain damage, improved behavioural performance in both Morris watermaze and object exploration tasks. However, prior exercise did not decrease to control levels the hyperactivity normally seen in KA-treated animals, as measured by ambulation in the open field. Furthermore, both exercise and enriched environment did not protect against neuron loss in CA1, CA2 and CA3 areas of the hippocampus, despite a substantial increase in brain-derived neutrophic factor (BDNF) levels in dentate gyrus of the exercise and KA-treated animals.

    Minović, Miroslav; Milovanović, Miloš; Starcevic, Dusan

    Our research in game based learning area is moving from traditional web-based Learning Management Systems towards game-based Learning Management Systems, with the intention of integrating upsides of using games in university education. This paper gives insight in to our recent work in area of reusability of Learning Objects between web-based LMSs and game-based LMSs. One of the major issues was how to use classical Learning Objects in development of educational games. We decided to apply a Model Driven Approach to Learning Objects repurposing, which represents a two-step process. Web based Learning Object is transformed into more abstract model and then returned enriched with game specific attributes to a platform specific model. For that purpose we propose a new term Educational Game Learning Object (EGLO). Different games that use different environment and settings can simply reuse Educational Game Learning Objects. Another contribution of our work is a software tool that can be used to import, transform, edit and add metadata, store and export Learning Objects. Applicability of this approach is demonstrated in one simple example.

    Transcriptional regulatory networks are being determined using “reverse engineering” methods that infer connections based on correlations in gene state. Corroboration of such networks through independent means such as evidence from the biomedical literature is desirable. Here, we explore a novel approach, a bootstrapping version of our previous Cross-Ontological Analytic method (XOA) that can be used for semi-automated annotation and verification of inferred regulatory connections, as well as for discovery of additional functional relationships between the genes. First, we use our annotation and network expansion method on a biological network learned entirely from the literature. We show how new relevant links between genes can be iteratively derived using a gene similarity measure based on the Gene Ontology that is optimized on the input network at each iteration. Second, we apply our method to annotation, verification, and expansion of a set of regulatory connections found by the Context Likelihood of Relatedness algorithm.

  16. Open Educational Resources and Informational Ecosystems: «Edutags» as a connector for open learning

    Directory of Open Access Journals (Sweden)

    Michael Kerres

    2014-10-01

    Full Text Available Teaching and learning in school essentially relies on analogous and digital media, artefacts and tools of all kinds. They are supported and provided by various players. The role of these players for providing learning infrastructures and the interaction between them are discussed in the following paper. Increasingly, Open Educational Resources (OER become available and the question arises how the interaction between these players is impacted. On the one hand, some players implement closed informational ecosystems that might provide a rich and coherent environment for learning, but also lock the users into a defined and often restricted environment. On the other hand, other players are interested in developing an infrastructure that supports open learning without the boundaries of closed informational ecosystems. Such open informational ecosystems must provide interconnections to numerous, in principal, unlimited number of platforms for learning contents. In the context of the project «Edutags» a reference platform is being implemented by way in which the contents of various providers are being connected and enriched through user-generated tags, commentaries and evaluations. The discussion points out that such an independent reference platform, operated separately from content platforms, must be considered as an important element in an open and truly distributed infrastructure for learning resources. Hence, we do not only need open educational resources to support open learning, we also need to establish an open informational ecosystem that supports such approaches.

    The isotopes of uranium that are found in nature, and hence in ‘fresh’ Yellowcake’, are not in relative proportions that are suitable for power or weapons applications. The goal of conversion then is to transform the U3O8 yellowcake into UF6. Conversion and enrichment of uranium is usually required to obtain material with enough 235U to be usable as fuel in a reactor or weapon. The cost, size, and complexity of practical conversion and enrichment facilities aid in nonproliferation by design.

    Bone platform switching involves an inward bone ring in the coronal part of the implant that is in continuity with the alveolar bone crest. Bone platform switching is obtained by using a dental fixture with a reverse conical neck. A retrospective study was performed to evaluate the effectiveness of conventional vs reverse conical neck implants. In the period between May 2004 and November 2007, 86 patients (55 females and 31 males; median age, 53 years) were operated and 234 implants were inserted: 40 and 194 were conventional vs reverse conical neck implants, respectively. Kaplan-Meier algorithm and Cox regression were used to detect those variables associated with the clinical outcome. No differences in survival and success rates were detected between conventional vs reverse conical neck implants alone or in combination with any of the studied variables. Although bone platform switching leads to several advantages, no statistical difference in alveolar crest resorption is detected in comparison with reverse conical neck implants. We suppose that the proximity of the implant abutment junction to the alveolar crestal bone gives no protection against the microflora contained in the micrograph. Additional studies on larger series and a combination of platform switching and bone platform switching could lead to improved clinical outcomes.

    Vaidya, Shrinand V; Virani, Siddharth; Phunde, Rajendra; Mahajan, Abhishek

    2016-01-01

    Background: Total joint arthroplasties of the hip and knee represent a remarkable feat of modern medicine in terms of reducing pain and restoring function to millions of patients afflicted with severe arthritis. Oftentimes, the performance and longevity of new implants and devices are based on limited data. This is the first study by a non-designer on the press fit condylar rotating platform posterior stabilized (PFC-RP-PS) design with 100’ success. This has a relevance, vis-á -vis bias that one may have in terms of reproducibility of technique and funding from the manufacturer. We associate our excellent mid-term results to intra operative technical aspects and stringent intra operative exclusion criteria. Materials and Methods: Our study includes a cohort of 121 selected knees operated between January 2003 and October 2010. We used cemented, posterior stabilized (PS), mobile bearing (MB), and RP prosthesis from the same manufacturer in all these 121 knees. The patients were evaluated bi-annually with the calculation of their Knee Society Scores (KSS) and a radiological assessment for loosening/osteolysis. Results: 120 knees were available for followup. The average Knee Society clinical and functional scores, respectively, were 27 points and 40 points preoperatively and 93 points and 95 points postoperatively. This indicates a mean increase of about 71’ in the clinical score and about 58’ in the functional score, which is statistically significant. The mean postoperative flexion was 124°, a mean increase of 23° from the preoperative flexion of 101°. There were no revisions (Kaplan-–Meier survivorship of 100’). Conclusions: We feel durable and reproducible results of PFC-RP-PS design knees are very technique sensitive. The way ahead with the PFC-RP-PS knees looks promising when the exclusion criteria for this design are strictly met. Coming from a non-designer, this study acquires a higher degree of relevance without any designer's or manufacturer

  17. Alternative and enriched housing systems for breeding does: a review

    2016-03-01

    Full Text Available The main results and observations on group and individually housed rabbit does were reviewed by Szendrő and McNitt in 2012, but in recent years several new papers in this field have been published. This provides a new opportunity to summarise the current knowledge on alternative housing systems for breeding does. In Switzerland, rabbit does are generally housed in group systems. The recently legislated Belgian and Dutch housing systems will be converted step by step into group housing systems. Recent research demonstrated that with semi-group housing systems much better performance levels are possible than with the Swiss group housing system. However, solutions to eliminate aggression, stress and injuries which are common among rabbit does in group housing systems have yet to be found. Some authors are of the opinion that individual cages are too small and allow limited possibilities for movement and social contact. Positive results were seen when platforms were inserted into the cages and the possibility for movement increased. The does and their kits could jump up and down using the platforms. Using footrests, the incidence of sore hocks declined. Several environmental enrichments which increase the well-being of rabbit does can also be used. These enriched cages (equipped with platforms, footrests, gnawing sticks, etc. are fully in line with animal welfare requirements. Increasing the size of cages and enriching them increases the production cost and the meat will be more expensive.

  18. Leveraging the power of Web 2.0 tools: a wiki platform as a multimedia teaching and learning environment in dental education.

    Science.gov (United States)

    Salajan, Florin D; Mount, Greg J

    2012-04-01

    This article presents the development and implementation of a wiki-based application for the delivery of educational content in dentistry. The Dental Procedure Education System (DPES) is a new web application that uses SharePoint to combine online collaborative authoring characteristic of wiki spaces with instructional video documentaries. Harnessing the wiki's versatility, DPES offers faculty members an avenue to develop an authoritative source of information for both students, through DPES Pro, and the public at large, through DPES Public. Principles of cognitive theory of multimedia learning, constructivist theory, and collaborative writing were employed in the development of DPES. An authoring protocol, with a clearly defined sequence of steps, was established in order to keep the production of the DPES procedures consistent and predictable. Initial, anecdotal user reports indicate that DPES is well received among dental students and faculty members. Expected outcomes and benefits of DPES use are discussed, and directions for research are proposed.

  19. Advanced offshore oil platforms

    Ellers, F.S.

    1982-04-01

    Four innovative offshore platforms that are designed to withstand 100-foot waves in waters 600-feet deep are described. These platforms are: (1) Stratfjord B Concrete Gravity-Base Platform; (2) Magnus Steel-Template-Jacket Platform; (3) Hutton Tension-Leg Platform; and (4) Block 280 Guyed Tower. The Statfjord B platform, designed in Norway, rests on four massive concrete columns with storage tanks at the base. It depends solely on its own mass for stability. The Magnus platform, designed by the British, is the heaviest offshore platform yet fabricated, weighing 41,000 tons. Two of the platform's four legs will incorporate flotation chambers so that the structure can be floated to its site in the North Sea. The Hutton structure, also designed in England, will consist of a buoyant hull tethered to the sea floor by slender steel tubes at its four corners. The first platform of its type, the Hutton structure is also destined for the North Sea. The US designed Block 280 guyed tower is designed for service in the Gulf of Mexico in water 1000 feet deep. It will be pinned to the sea floor by a spokelike array of 20 steel cables, each one more than 3000 feet long. The tower and its guys will weigh 43,000 tons, slightly more than the Magnus steel-template jacket and more than four time as much as the Eiffel Tower. At a cost of approximately $2.6 billion, the Magnus is the most expensive offshore platform to date. The Statfjord B was put into production in 1982. The Magnus is scheduled for oil production in 1983. The Hutton and the Block 280 will both be producing in 1984. (JMT)

    Abdelhamid Zouhair

    2014-06-01

    Full Text Available This paper presents our work in the field of Intelligent Tutoring System (ITS, in fact there is still the problem of knowing how to ensure an individualized and continuous learners follow-up during learning process, indeed among the numerous methods proposed, very few systems concentrate on a real time learners follow-up. Our work in this field develops the design and implementation of a Multi-Agents System Based on Dynamic Case Based Reasoning which can initiate learning and provide an individualized follow-up of learner. This approach involves 1 the use of Dynamic Case Based Reasoning to retrieve the past experiences that are similar to the learner’s traces (traces in progress, and 2 the use of Multi-Agents System. Our Work focuses on the use of the learner traces. When interacting with the platform, every learner leaves his/her traces on the machine. The traces are stored in database, this operation enriches collective past experiences. The traces left by the learner during the learning session evolve dynamically over time; the case-based reasoning must take into account this evolution in an incremental way. In other words, we do not consider each evolution of the traces as a new target, so the use of classical cycle Case Based reasoning in this case is insufficient and inadequate. In order to solve this problem, we propose a dynamic retrieving method based on a complementary similarity measure, named Inverse Longest Common Sub-Sequence (ILCSS. Through monitoring, comparing and analyzing these traces, the system keeps a constant intelligent watch on the platform, and therefore it detects the difficulties hindering progress, and it avoids possible dropping out. The system can support any learning subject. To help and guide the learner, the system is equipped with combined virtual and human tutors.

  1. Female C57BL/6 mice show consistent individual differences in spontaneous interaction with environmental enrichment that are predicted by neophobia.

    Walker, Michael D; Mason, Georgia

    2011-10-10

    Environmental enrichment typically improves learning, increases cortical thickness and hippocampal neurogenesis, reduces anxiety, and reduces stereotypic behaviour, yet sometimes such effects are absent or even reversed. We investigated whether neophobia governs how mice interact with enrichments, since this could explain why enrichments vary in impact. Female C57BL/6 mice, previously screened for neophobia, had free access to enriched cages connected to their standard cages. The relative consumption of food in each cage revealed approximate dwelling times; the use of two enrichments was also measured. High neophobia significantly predicted reduced use of the enriched cage. Thus even within this homogeneous population, provided with identical enrichments, differential neophobia predicted differential enrichment use.

  4. ENRICHMENT OF OBO ONTOLOGIES

    Bada, Michael; Hunter, Lawrence

    2006-01-01

    This paper describes a frame-based integration of the three GO subontologies, the Chemicals of Biological Interest ontology (ChEBI), and the Cell Type Ontology (CTO) in which relationships between elements of the ontologies are modeled in a way that better captures the relational semantics between biological concepts represented by the terms, rather than between the terms themselves, than previous frame-based efforts. We also describe a methodology for creating suggested enriching assertions of the form (subject, relationship, object) by identifying patterns in GO terms, mapping these patterns and subpatterns to relationships, matching concepts to these patterns and subpatterns, and integrating these assertions into the ontologies. Using this methodology, a large number of reliable assertions linking previously unlinked OBO terms using a wide variety of specific, hierarchically arranged relationships were created: A predicted assertion was made for 62% of GO terms that matched one of 31 patterns, and 97% of these predicted assertions were assessed to be valid; a further 429 assertions (corresponding to 6% of the matching terms) were manually created, resulting in an initial set of 4,497 assertions. Furthermore, this methodology programmatically integrates assertions into a base ontology such that each assertion is fully consistent with respect to higher (i.e., more general) relevant class and slot levels. Such an integration is absent from previous compositional efforts, and we argue its necessity for the creation of coherent biological ontologies when linking previously unlinked terms. PMID:17011833

  5. Earthquake forecast enrichment scores

    Directory of Open Access Journals (Sweden)

    Christine Smyth

    2012-03-01

    Full Text Available The Collaboratory for the Study of Earthquake Predictability (CSEP is a global project aimed at testing earthquake forecast models in a fair environment. Various metrics are currently used to evaluate the submitted forecasts. However, the CSEP still lacks easily understandable metrics with which to rank the universal performance of the forecast models. In this research, we modify a well-known and respected metric from another statistical field, bioinformatics, to make it suitable for evaluating earthquake forecasts, such as those submitted to the CSEP initiative. The metric, originally called a gene-set enrichment score, is based on a Kolmogorov-Smirnov statistic. Our modified metric assesses if, over a certain time period, the forecast values at locations where earthquakes have occurred are significantly increased compared to the values for all locations where earthquakes did not occur. Permutation testing allows for a significance value to be placed upon the score. Unlike the metrics currently employed by the CSEP, the score places no assumption on the distribution of earthquake occurrence nor requires an arbitrary reference forecast. In this research, we apply the modified metric to simulated data and real forecast data to show it is a powerful and robust technique, capable of ranking competing earthquake forecasts.

  6. City model enrichment

    Science.gov (United States)

    Smart, Philip D.; Quinn, Jonathan A.; Jones, Christopher B.

    The combination of mobile communication technology with location and orientation aware digital cameras has introduced increasing interest in the exploitation of 3D city models for applications such as augmented reality and automated image captioning. The effectiveness of such applications is, at present, severely limited by the often poor quality of semantic annotation of the 3D models. In this paper, we show how freely available sources of georeferenced Web 2.0 information can be used for automated enrichment of 3D city models. Point referenced names of prominent buildings and landmarks mined from Wikipedia articles and from the OpenStreetMaps digital map and Geonames gazetteer have been matched to the 2D ground plan geometry of a 3D city model. In order to address the ambiguities that arise in the associations between these sources and the city model, we present procedures to merge potentially related buildings and implement fuzzy matching between reference points and building polygons. An experimental evaluation demonstrates the effectiveness of the presented methods.

There have been significant technical improvements since the early methods for microsatellite isolation were developed, and today the most common procedures take advantage of the hybrid capture methods of enriched-targeted microsatellite DNA. Furthermore, recent advents in sequencing technologies (i.e., next-generation sequencing, NGS) have fostered the mining of microsatellite markers in non-model organisms, affording a cost-effective way of obtaining a large amount of sequence data potentially useful for loci characterization. The rapid improvements of NGS platforms together with the increase in available microsatellite information open new avenues to the understanding of the evolutionary forces that shape genetic structuring in wild populations. Here, we provide detailed methodological procedures for microsatellite isolation based on the screening of GT microsatellite-enriched libraries, either by cloning and Sanger sequencing of positive clones or by direct NGS. Guides for designing new species-specific primers and basic genotyping are also given.

    Maternal choline diet is known to affect the processes of spatial learning. We report here our studies of learning ability in the Morris swimming test in the adult offspring of maternal rats given a methyl-containing supplement enriched with choline and betaine during pregnancy and lactation. Increases in the time taken to find the invisible platform and the duration of swimming close to the vessel walls were seen, these demonstrating worsening of learning ability in response to the maternal diet. Changes in the platform search strategy were not associated with increases in anxiety in male rats. The possible role of a maternal methyl-containing diet in altering the expression of genes controlling the development of the nervous system is discussed.

    The Moodle platform has been used to put into practice an ongoing evaluation of the students' Physics learning process. The evaluation has been done on the frame of the course General Physics, which is lectured during the first year of the Physics, Mathematics and Electronic Engineering Programmes at the Faculty of Science and Technology of the University of the Basque Country (UPV/EHU). A test bank with more than 1000 multiple-choice questions, including conceptual and numerical problems, has been prepared. Throughout the course, the students have to answer a 10-question multiple-choice test for every one of the blocks the course is divided in and which were previously treated and worked in the theoretical lectures and problem-solving sessions. The tests are automatically corrected by Moodle, and under certain criteria, the corresponding mark is taken into account for the final mark of the course. According to the results obtained from a statistical study of the data on the student performances during the last four academic years, it has been observed that there exists an actual correlation between the marks obtained in the Moodle tests and the final mark of the course. In addition, it could be deduced that students who have passed the Moodle tests increase their possibilities of passing the course by an odds ratio close to 3.

  16. The nature of mathematical enrichment: a case study of implementation

    2007-12-01

    Full Text Available This paper reports a framework for describing the nature of mathematics enrichment that emerged from a case study based on the work of the NRICH Project (www.nrich.maths.org team when producing “mathematics enrichment trails” (an ordered set of related mathematics problems and support materials. A range of data sources, including the trails, trail development sessions, related literature and the views of colleagues were used to inform the findings. The data were analysed using NVivo and involved the development of two complementary coding systems. One, drawn from the data itself, gave evidence of views of the content aspects of mathematical enrichment. The other, specifically designed and informed by the literature, was used to aid the analysis of the roles of teaching and learning inherent in views of enrichment described by participants. The framework describes the content of an enrichment curriculum as well as implications for teaching and learning, the experiences of learners and the features of settings where this occurs. To support this, some detail is provided on the role, nature and purpose of problem-solving and what constitutes a good problem. While emerging from a particular context, the framework highlights the need for debate concerning the audience for mathematics enrichment, particularly in questioning the commonly held belief that its value is in supporting the needs of the mathematically most able. The framework also has potential value through offering a focus for debate within the wider community concerning the nature of mathematics enrichment and as a reference point for evaluating the potential of existing or new curriculum to deliver mathematics enrichment.

    2009-07-01

    Full Text Available Abstract Background Integration of biological knowledge encoded in various lists of functionally related genes has become one of the most important aspects of analyzing genome-wide functional genomics data. In the context of cluster analysis, functional coherence of clusters established through such analyses have been used to identify biologically meaningful clusters, compare clustering algorithms and identify biological pathways associated with the biological process under investigation. Results We developed a computational framework for analytically and visually integrating knowledge-based functional categories with the cluster analysis of genomics data. The framework is based on the simple, conceptually appealing, and biologically interpretable gene-specific functional coherence score (CLEAN score. The score is derived by correlating the clustering structure as a whole with functional categories of interest. We directly demonstrate that integrating biological knowledge in this way improves the reproducibility of conclusions derived from cluster analysis. The CLEAN score differentiates between the levels of functional coherence for genes within the same cluster based on their membership in enriched functional categories. We show that this aspect results in higher reproducibility across independent datasets and produces more informative genes for distinguishing different sample types than the scores based on the traditional cluster-wide analysis. We also demonstrate the utility of the CLEAN framework in comparing clusterings produced by different algorithms. CLEAN was implemented as an add-on R package and can be downloaded at http://Clusteranalysis.org. The package integrates routines for calculating gene specific functional coherence scores and the open source interactive Java-based viewer Functional TreeView (FTreeView. Conclusion Our results indicate that using the gene-specific functional coherence score improves the reproducibility of the

    This project was created to provide a National Community Solar Platform (NCSP) portal known as Community Solar Hub, that is available to any entity or individual who wants to develop community solar. This has been done by providing a comprehensive portal to make CEC’s solutions, and other proven community solar solutions, externally available for everyone to access – making the process easy through proven platforms to protect subscribers, developers and utilities. The successful completion of this project provides these tools via a web platform and integration APIs, a wide spectrum of community solar projects included in the platform, multiple groups of customers (utilities, EPCs, and advocates) using the platform to develop community solar, and open access to anyone interested in community solar. CEC’s Incubator project includes web-based informational resources, integrated systems for project information and billing systems, and engagement with customers and users by community solar experts. The combined effort externalizes much of Clean Energy Collective’s industry-leading expertise, allowing third parties to develop community solar without duplicating expensive start-up efforts. The availability of this platform creates community solar projects that are cheaper to build and cheaper to participate in, furthering the goals of DOE’s SunShot Initiative.

    In FY13, Pacific Northwest National Laboratory (PNNL) with funding from the Department of Energy’s (DOE’s) Building Technologies Office (BTO) designed, prototyped and tested a transactional network platform to support energy, operational and financial transactions between any networked entities (equipment, organizations, buildings, grid, etc.). Initially, in FY13, the concept demonstrated transactions between packaged rooftop air conditioners and heat pump units (RTUs) and the electric grid using applications or "agents" that reside on the platform, on the equipment, on a local building controller or in the Cloud. The transactional network project is a multi-lab effort with Oakridge National Laboratory (ORNL) and Lawrence Berkeley National Laboratory (LBNL) also contributing to the effort. PNNL coordinated the project and also was responsible for the development of the transactional network (TN) platform and three different applications associated with RTUs. This document describes two applications or "agents" in details, and also summarizes the platform. The TN platform details are described in another companion document.

    Although there are a number of visualization systems to choose from when analyzing data, only a few of these allow for the integration of other visualization and analysis techniques. There are even fewer visualization toolkits and frameworks from which one can develop ones own visualization applications. Even within the research community, scientists either use what they can from the available tools or start from scratch to define a program in which they are able to develop new or modified visualization techniques and analysis algorithms. Presented here is a new general-purpose platform for constructing numerous visualization and analysis applications. The focus of this system is the design and experimentation of new techniques, and where the sharing of and integration with other tools becomes second nature. Moreover, this platform supports multiple large data sets, and the recording and visualizing of user sessions. Here we introduce the Universal Visualization Platform (UVP) as a modern data visualization and analysis system.
