Ten years of Educational Robotics in a Primary School
No full textMany researchers and teachers agree that the inclusion of science, technology, engineering, and mathematics in early education provides strong motivation and greatly improves the speed of learning. Most primary school curricula include a number of concepts that cover science and mathematics, but less effort is placed in teaching problem-solving, computer science, technology and robotics. The use of robotic systems and the introduction of robotics as a curriculum subject educates children in the basics of technology, and gives them additional human and organizational values. This paper presents a new program introduced in an Italian primary school, thanks to a collaboration with National Instruments and Università Politecnica delle Marche. Specifically, the project’s curricular aim was to improve logic, creativity, and the ability to focus, all of which are lacking in today’s generation of students. The subject of robotics will be part of the primary school’s curriculum for all five years. The program has delivered training to the teachers, and a complete program in which children have demonstrated great learning abilities, not only in technology, but also in collaboration and teamwork
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
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
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
Low-Environmental Impact Routeing of Overhead Power Lines for the Connection of Renewable Energy Plants to the Italian HV Grid
No full textRouting of high voltage electric transmission lines for the connection of renewable energy distributed generation plants is a critical issue from an environmental point of view. A standard methodology that incorporates multiple weighted perspectives of influence is useful in the route approval by the governmental and regulating permitting entities and the support of the affected public. In this paper we investigate the suitability of the procedure employed by Terna, the leading electricity HV transmission grid operator, to identify the corridors with lower environmental impact where to route the new overhead transmission lines. The methodology is named ERPA and it is based on the subdivision of all the relevant constraints dictated by environmental issues and territory legislations in four classes: Exclusion, Rejection, Problem and Attraction. The case study that we take into account concerns the design and connection of a wind-farm placed near Collarmele, in the centre of Italy
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
A feasibility study of using MV and LV distributed energy resources flexibility in a TSO/DSO coordination perspective: the case study of Milan, Italy
Full text linkThe massive penetration of Renewable Energy Sources, preminently wind and photovoltaic power plants, and Distributed Energy Resources (DERs), such as Combined Heat and Power plants, Battery Energy Storage System, Electric Vehicles impose additional challenges in power system planning and operation. Pushing towards a low-carbon electricity system can increase potential issues such as congestion management, voltage control, controllability, observability, and generation-load forecasting. In this context, coordinated actions between Transmission System Operators (TSOs) and Distribution Systems Operators (DSOs) could be a valuable solution. For instance, through the DERs installed on the distribution network, the DSO could help the TSO to relieve a network contingency on the HV/HHV grid. This paper proposes a feasibility study of TSO-DSO coordination that allows using DERs to solve transmission network criticalities, both in operational and short- to medium-term time horizons, that does not involve the exchange of sensitive information between the two utilities. A straightforward algorithm is proposed for evaluating DERs available flexibility in terms of active and reactive power, and for estimating the aggregated capability curve at the point of common coupling, i.e., the flexibility available downstream a HV/MV substation. The proposed algorithm has been applied to Milan's case study using real data from Unareti, the local DSO, and Terna, the Italian TSO
