Efficiency in the use of natural non-renewable resources from mining and quarrying in Italy. Time series analysis and Economy-wide Material Flows Acc…

2012

Political reasons have been pushing towards a process of decentralization of powers and responsibilities since last twenty years in Italy. The regional management of mining and quarrying (m&q) should be an interesting case study of this change. This process has begun in the ’70s with the Pres. Decree N. 616 of 1977. By examining administrative data and Regional Laws, this paper highlights how misleading is the awareness of policy makers of the real value of raw mineral resources domestically extracted: they seem closer to common goods rather than to public goods. By combining data on local governance with official statistics of Economy-wide Material Flow Accounts (EW-MFA), our econometric a…

Karnawalizacja górniczego świętowania

2019

Autorka w artykule przywołuje opisy sposobów obchodzenia dnia św. Barbary, patronki górników, począwszy od XIX wieku do czasów współczesnych. Analizując obyczaj w tak długim czasie, mogła prześledzić proces przemian zachodzących w strategii świętowania tej uroczystości. Na odnotowywane przeobrażenia wpływały różne czynniki w zależności od okresu w dziejach regionu. W dobie pruskiej o pojawiających się nowych wariantach tego święta decydowały dwa czynniki. Z jednej strony, z powodu kryzysu kultury, jaki przeżywał industrialny, zurbanizowany świat tej doby, prowadzący do rozpadu społeczności tradycyjnych, środowiska robotnicze zaczęły otwierać się na tani sentymentalizm, powierzchowność w doś…

Toxicity of biomining effluents to Daphnia magna : Acute toxicity and transcriptomic biomarkers

2018

Increasing metal consumption is driving the introduction of new techniques such as biomining to exploit low grade ores. The biomining impacts notably aquatic ecosystems, yet, the applicability of ecotoxicological tests to study the complex mixture effects of mining waters is insufficiently understood. The aim of the present work was to test if transcriptomic biomarkers are suitable and sensitive for the ecotoxicity assessment of biomining affected waters. The study site had been affected by a multimetal biomine, and the studied water samples formed a concentration gradient of contamination downstream from the biomining site. Cadmium and nickel were used as positive controls in the toxicity …

A visualization technique for accessing solution pool in interactive methods of multiobjective optimization

2015

<pre>Interactive methods of <span>multiobjective</span> optimization repetitively derive <span>Pareto</span> optimal solutions based on decision maker's preference information and present the obtained solutions for his/her consideration. Some interactive methods save the obtained solutions into a solution pool and, at each iteration, allow the decision maker considering any of solutions obtained earlier. This feature contributes to the flexibility of exploring the <span>Pareto</span> optimal set and learning about the optimization problem. However, in the case of many objective functions, the accumulation of derived solutions makes accessing the sol…

HLA-B27-restricted T cells from patients with ankylosing spondylitis recognize peptides from B*2705 that are similar to bacteria-derived peptides

2003

SUMMARY Ankylosing spondylitis (AS) is an inflammatory systemic disease affecting the spine, sacroiliacal and peripheral joints. Although the aetiology of AS remains unknown, the strong association with the HLA-B27 allele might reflect directly a detrimental effect of the HLA-B27 molecule itself, resulting from its potential capability to present ‘arthritogenic’ peptides to CD8+ T cells. Because some forms of SpA are triggered by enterobacterial infection, such arthritogenic peptides might originate from autologous and/or bacterial proteins triggering cross-reactive CD8+ T cell clones. Intriguingly, two peptides from the second extracellular domain of HLA-B*2705 share sequence homologies wi…

Performance Evaluation for a Sustainable Supply Chain Management System in the Automotive Industry Using Artificial Intelligence

2020

Increasing the sustainability of a system can be achieved by evaluating the system, identifying the issues and their root cause and solving them. Performance evaluation translates into key performance indicators (KPIs) with a high impact on increasing overall efficacy and efficiency. As the pool of KPIs has increased over time in the context of evaluating the supply chain management (SCM) system&rsquo

Information Extraction from Binary Skill Assessment Data with Machine Learning

2021

Strength training exercises are essential for rehabilitation, improving our health as well as in sports. For optimal and safe training, educators and trainers in the industry should comprehend exercise form or technique. Currently, there is a lack of tools measuring in-depth skills of strength training experts. In this study, we investigate how data mining methods can be used to identify novel and useful skill patterns from a binary multiple choice questionnaire test designed to measure the knowledge level of strength training experts. A skill test assessing exercise technique expertise and comprehension was answered by 507 fitness professionals with varying backgrounds. A triangulated appr…

Web Usage Mining and Website Effectiveness

2020

Nel seguente articolo sono state utilizzate tecniche di Usage Mining al fine di valutare l’efficacia del website di un’azienda di ricettività turistica distinguendo tra comportamento di navigazione di utenti PC e utenti mobile. I risultati ottenuti hanno evidenziato problematiche relative alla progettazione del sito in questione. Using usage mining techniques, the study explores the effectiveness of a tourism business website focussing on the differences between desk and mobile user browsing behaviour. Results indicate important direction for a rethink of the website design.
