Chapter 4</br>Will our children have the chance to do research on today’s digital books?
2016
In this chapter, I will first position my considerations about the sustainability of ebooks for future research in the context of book history; moreover, I will introduce basic concepts of (migration and emulation) as well as challenges to the long-term preservation of digital data in greater generality. After that and taking current research on past (printed) books as an analogy, I shall try to outline which kinds of (digital) material will be indispensable in the future to do research on today's digital book production: published digital materials and unique (digital) artefacts. Finally, I shall present the results of my exemplary studies to find out which precautions for the future avail…
Do general innovation policy tools fit all? Analysis of the regional impact of the Norwegian Skattefunn scheme
2017
Background: The paper examines the regional effects of a general innovation policy, i.e. a policy tool that does not target specific industries or subnational regions. General policy tools are an important part of the portfolio of innovation policy measures. However, there is a question over whether general tools are equally relevant for all types of firms, irrespective of their size, sector and location. Findings: The economic geography and innovation study literature, as well as the EU’s Smart Specialization approach, are based on the view that innovation policy tools must be adapted to specific regional conditions. General policy tools are insufficient unless they are adapted to individu…
Photovoltaic based active generator: Energy control system using stateflow analysis
2015
At present, most of the grid connected photovoltaic (PV) systems are operating at maximum power points and injecting power in uncontrolled way. Thus, active generator will be a good solution to support instantaneous power balance, frequency control and maintaining the power quality with controllable power injection. This new mode of active generator needs innovative power management. The new proposed energy control system for active generator might help to manage the energy within the micro-grid environment. In this work, the focus is to manage the energy among the PV based active generator, load and interconnected grid and energy controller architecture for that purpose is presented. It co…
A description model for regeneration through urban tourism in rural towns with underused historic real estate
2016
Il presente contributo propone un modello di descrizione (description model) che trova applicazione in una situazione reale di aiuto alla decisione posto dall'urbanista per lo sviluppo turistico delle città rurali nelle zone dell'entroterra siciliano. Il problema decisionale riguarda la città di Cianciana (AG), che negli ultimi anni si è resa protagonista di un particolare fenomeno di turismo internazionale. In particolare, proponiamo un quadro valutativo multicriteriale per la riqualificazione fisica ed economica del centro storico della città attraverso lo sviluppo del turismo. Il modello presentato, relativo a un problema decisionale di tipo descrittivo, è orientato a supportare i deciso…
Mejorando el procesamiento macro-estructural en L2 en estudiantes con niveles de inglés elementales o intermedios: un procedimiento instruccional cen…
2014
Previous studies have shown that students have difficulties building the macro-structure from expository texts in English (as L2). The usual cause pointed out is a lack of language proficiency. Thus, instructional methods have focused on providing students with the necessary vocabulary and grammar knowledge. This study proposes and validates an instructional approach which improves students’ L2 processing on the macro-structural level, focusing on reading strategies rather than on vocabulary or grammar. Comprehension monitoring on the macro-structural level was improved by performing instructional tasks devoted to establish global coherence. As a consequence, students’ reading comprehension…
Depuration of geosmin- and 2-methylisoborneol-induced off-flavors in recirculating aquaculture system (RAS) farmed European whitefish
2019
European whitefish Coregonus lavaretus has increasingly become an important species for aquatic food production, especially in the Nordic countries. Whitefish is produced in traditional cage and pond operations, and in recirculating aquaculture system (RAS) in which, unfortunately, off-flavors and odors, mostly caused by geosmin (GSM) and 2-methylisoborneol (MIB), can accumulate in fish flesh from the circulating water. GSM and MIB have very low human sensory detection limits and, therefore, often disliked by consumers even at low concentrations. In this study, concentrations of GSM and MIB in RAS farmed European whitefish were studied by an analytical method based on headspace solid phase …
Henneguya zschokkei (Myxozoa) infection in cultured whitefish : Age-dependence, seasonality and distribution within host
2017
Whitefish (Coregonus lavaretus) is an important species for European fisheries and aquaculture. Recently, the myxosporean Henneguya zschokkei has been observed to infect the muscles of whitefish in fish farms. Plasmodia of H. zschokkei prevent marketing of the fillet and cause economic losses. The factors associated with occurrence of the parasite in fish farms have not been investigated previously. We studied age-dependence, seasonality, and within-host distribution of H. zschokkei plasmodia in farmed whitefish by examining a total of 1599 fish. Distribution of plasmodia within the fish was not uniform. When the fillet was divided into parts, the number of plasmodia was positively correlat…
Une quête d'exactitude : machines, algèbre et géométrie pour la construction traditionnelle des équations différentielles
2015
In La Géométrie, Descartes proposed a “balance” between geometric constructions and symbolic manipulation with the introduction of suitable ideal machines. In particular, Cartesian tools were polynomial algebra (analysis) and a class of diagrammatic constructions (synthesis). This setting provided a classification of curves, according to which only the algebraic ones were considered “purely geometrical.” This limit was overcome with a general method by Newton and Leibniz introducing the infinity in the analytical part, whereas the synthetic perspective gradually lost importance with respect to the analytical one—geometry became a mean of visualization, no longer of construction. Descartes’s…
Doni funesti. Miti di scambi pericolosi nella letteratura latina
2018
«I doni sono come gli ami» avverte Marziale. «Catturano anche gli dèi» afferma Ovidio. «Sono l’inganno in cui di solito incappano i re» osserva Seneca. La forza calamitante del dono, la sua natura seducente e pericolosa, emerge con chiarezza dall’analisi del sapere mitico romano e delle sue riscritture letterarie. I Romani, del resto, conoscevano bene il potere attrattivo dei doni, la loro capacità di condizionare i comportamenti e le dinamiche di relazione. Erifile è soggiogata dalla collana di Armonia, Mida è accecato dalla sua fame d’oro, Creusa è ingannata dai doni nuziali; Didone brucia con sé quelli dell’amato, Semele e Fetonte ne saranno bruciati. Il dono promesso è un rischio, il do…
L'albero di Persefone. Una nota introduttiva
2022
Il saggio discute il documentario di O. Cavalcanti, Persefone rivisitata, accurata e partecipata indagine sull’originale rito della Domenica delle Palme di Bova. In questa occasione sono recati processionalmente dei peculiari artefatti cerimoniali le pupazze, complessi intrecci di listelli di canna e di rami e foglie d’ulivo, rivestiti di fiori e di frutti. Intesi a rappresentare delle figure femminili, le pupazze sono destinate, al termine del rito processionale, ad essere smembrate e distribuite tra i fedeli affinché essi possano portare con sé, nelle proprie dimore, nei luoghi di lavoro una parte della potenza sacrale in esse racchiusa. In tutta evidenza le peculiari forme del rito e dei…
