Self organizing maps as a novel tool for data analysis in education
2016
Young people currently live and are connected to the virtual world in a natural and simple way. Nevertheless, in spite of the great advantages of the use of Information and Communication Technology, and particularly social networks, there are several drawbacks, principally security and privacy of net users. However, human behaviour is strongly non-linear, so usual statistical analysis does not yield accurate results. Now, machine learning algorithms are very common in solving real life non-linear problems, such as economics, medicine and engineering. So it would be worthy to apply this methodology on education data sets. In this work, a non-linear, visual algorithm named Self Organizing Map…
Fizikāli – ķīmiskās pirmapstrādes un enzimātiskās hidrolīzes efektivitātes paaugstināšana bioetanola ražošanai no lignocelulozes substrāta
2020
Bioetanola ražošanai no lignocelulozes substrāta īpaši nozīmīgi ir pirmie soļi – pirmapstrāde un hidrolīze. Ir pētītas daudzas fizikālās, ķīmiskās un bioloģiskās pirmapstrādes metodes un enzimātiskās hidrolīzes parametri. Šajā darbā veikts miežu salmu un siena pirmapstrādes ar eksplozīvu dekompresiju (izmantojot N2) gāzi novērtējums, kā arī hidrolīzes optimālās temperatūras novērtējums. Rezultāti sakrīt ar literatūrā minēto, ka pirmapstrādes optimālā temperatūra ir 150º C. Tomēr ņemot vērā samērā nelielo pieaugumu, vismaz daļā eksperimentu pirmapstrādi var aizvietot ar enzimātiskās hidrolīzes temperatūras paaugstināšanu, ietaupot enerģijas patēriņu. Biomasu, kuru ir grūti izmantot etanola i…
Przeżytek teorii systemowej i metodologiczne rozwiązania The Coaching Maps
2018
W praktyce coachingowej, konsultingowej i doradczej, odwołując się do teorii systemowej, często pomija się krytykę wspomnianej teorii. W niniejszym artykule przedstawione zostaną założenia klasycznej teorii systemowej w różnych naukach oraz ich krytyka. Ta ostatnia dotyczy przede wszystkim prymatu systemu nad człowiekiem, braku jego refleksyjności i podmiotowości, zmiany granic systemowych. Naszą propozycją odpowiedzi na elementy krytyki teorii systemowej jest autorska metodologia The Coaching Maps, oparta m.in. na hermeneutyce, a zakładająca wykorzystanie etnografii obrazu w procesie badawczym/diagnostycznym i coachingowo- szkoleniowym. Z kolei pojęcie systemu jako zamkniętej całości w okr…
Rockfall hazards of Mount Pellegrino area (Sicily, Southern Italy)
2020
A map derived by rockfall analysis at Mount Pellegrino is presented herein. The study area is affected by several phenomena of rockfall which caused numerous damage and a strong social and economic impact. Official reports and maps that give a general assessment of rockfall hazard are available in this respect, however, it would be advisable to provide a more specific cartographic support useful for land management and planning. The drafting of new maps showing the rockfall runout areas is an additional tool that may be used in conjunction with the existing maps as a means of risk mitigation and reduction. On the basis of geological, geomorphological, and geomechanical analysis and exploiti…
Multidisciplinary Approach to Rainfall-Triggered Rockfalls: the Case Study of the Disaster of the Ancient Hydrothermal Sclafani Spa (Madonie Mts., No…
2017
Abstract. In 1851, the region of Sicily experienced many rainstorm-induced landslides. On 13 March 1851, a rainstorm brought about a severe rockfall disaster near the small town of Sclafani (Madonie Mountains, northern-central Sicily, Italy). Rocks detached from the carbonate crest of Mt. Sclafani (813 m above sea level) fell downslope, causing the collapse of the ancient hydrothermal spa (about 430 m above sea level) and burying it under their fragments. Fortunately, the event did not cause injuries or victims. Given its geological, geomorphological and structural features, the calcareous-dolomitic and carbonate-siliciclastic relief of Mt. Sclafani is extremely prone to landsliding. This s…

A VIRTUAL HUB BROKERING APPROACH FOR INTEGRATION OF HISTORICAL AND MODERN MAPS
2016
Geospatial data are today more and more widespread. Many different institutions, such as Geographical Institutes, Public Administrations, collaborative communities (e.g., OSM) and web companies, make available nowadays a large number of maps. Besides this cartography, projects of digitizing, georeferencing and web publication of historical maps have increasingly spread in the recent years. In spite of these variety and availability of data, information overload makes difficult their discovery and management: without knowing the specific repository where the data are stored, it is difficult to find the information required and problems of interconnection between different data sources and th…
The Coaching Maps as a Tool for Developing Reflectivity in Organisations
2019
Our view of organizations, labour and the competencies of managers will soon need to change. In the postmodern and post-Fordist world, economy and organizations function differently than they did in the 20th century. Workers and managers will have to face new expectations. Not only has reflectivity become one of the key organisational factors; it is also taught, learnt and shaped. Drawing on an authoethnographic model and action-research, authors of this paper provide an education and development tool that managers and workers can use to develop and trigger reflectivity. Picture ethnography, coaching philosophy and hermeneutics are theoretical bases for the construction of a new model of se…
