Batch Experiment: A Fruitful Way of Combining Hands-On Laboratory and E-Learning
Full text linkIn this study, the authors present the utilization of laboratory-based Learning at the University of Parma and its integration with DigiLab4U (Open Digital Laboratory for You). At the University of Parma, the course of AUTO-ID in production and logistics from the very beginning has exploited the lab-based learning to convey practical skills gained in RFID (Radio Frequency IDentification) Laboratory to the students through a hands-on laboratory. However, due to the COVID-19 pandemic and consequent measures taken by the Italian government, the very same method could not be used anymore during the spring semester of the year 2020. To solve the issue a batch experiment method has been adopted, where the parameters were set by students and the experiment was carried out by a researcher. During the experiments, the researchers gather raw data and send it back to the students. Having these data, the students were able to perform the data analysis. To give the students the possibility to better understand the environment of the laboratory, pictures, and videos of the experiment performance have been supplied too. To complete the batch experiment, a tutorial has also been provided with the details of the software set up and the components used. The total remotization of RFID Laboratory is scheduled for late 2021
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Guideline to Safety and Security in Federated Remote Labs
Full text linkThe interest of the educational community in the laboratory- (lab) based education has grown steadily. As remote labs have started to be a reliable alternative to traditional hands-on labs, security and safety issues are becoming increasingly important, as their interconnected nature raises new and challenging issues. The complexity increases when multiple institutions are involved in a federated lab infrastructure. This paper provides a guideline for assessing safety and security in federated labs following the VDI/VDE 2182 guideline and verifies the concept based on remote labs in three different academic institutions
Non-Traditional Labs and Lab Network Initiatives: A Review
No full textLab-based education has always played an important role in teaching students. Making remote and virtual labs communicate with one another by creating networks of labs can enhance the traditional way of learning as well as reduce the costs of implementing and using labs. This paper provides a review of the literature on non-traditional labs and lab network initiatives up to 2020. With the term ‘non-traditional labs’, we mean virtual, remote and hybrid labs, whereas with the term ‘lab network’, we indicate a set of two or more cooperating labs typically connected through the internet. In this study, we used a recent and comprehensive framework for data collection, organization, and analysis to gather information on 40 non-traditional labs and lab network initiatives. Thanks to this framework, the outcomes of our work highlight interesting trends of lab-based education, which pertain to didactical, organizational, and technical aspects
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Safety and Security in Federated Remote Labs – A Requirement Analysis
No full textRecently, the interest of the educational community in laboratory- (lab-) based education has grown steadily. As remote and virtual labs have started to be a reliable alternative to traditional hands-on labs, security and safety issues are becoming increasingly important, especially in the case of remote laboratories, as their interconnected nature raises new and challenging issues. When multiple institutions are involved in a federated labs infrastructure, the complexity increases. Since a structured approach to assess safety and security for federated remote labs is missing, this paper aims at clarifying the general requirements to be considered and proposes a general concept for assessing safety and security in federated labs. Firstly, we analyze the current state on safety and security in remote labs by means of a literature review. Secondly, we investigate existing requirements and define operational requirements for a safety and security guideline in federated remote labs. Thirdly, we provide an overview about standardization approaches and existing guidelines and suggest a guideline, which matches our requirements analysis
Digilab4u: General architecture for a network of labs
No full textThe paper presents the architecture designed to create a network of remote and virtual laboratories, to integrate and enhance them with new technologies and methods for lab-based education, within five universities inside the Open Digital Lab For You (DigiLab4U) project. Many factors lead to an increase in interest in networks of labs. The main ones aim on increasing the exploitation of laboratory equipment, together with the increasing necessity of practical experience in students’ careers. Lead by this necessity, the network developed an education environment with a strong focus on Industry 4.0 and Industrial Internet of Things. Moreover, its aim is the integration of new technologies and alternative teaching methods within the environment through an iterative approach. Compliant with these objectives and considering the standards available for such concepts, a new architecture of a network has been created based on the Industrial Reference Internet Architecture. With respect to these standards, the general architecture has been built as a client-server architecture composed of three elements: (i) Client, (ii) Web server, and (iii) Local server. We also took into consideration that the project aims to enlarge the network in the future, making it accessible from different institutions all over the world, to enable the learners to perform new experiments and enhance their skills. Besides, it enables the integration of technologies such as Serious Games and Learning Analytics, as they are becoming more and more widespread and necessary for teaching and assessing the students. To ease the understanding and the scalability of the network, three different points of view architecture has been proposed, by splitting and describing it into software, hardware, and logical perspectives
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
