Is there a Nordic model of final disposal of spent nuclear fuel? Governance insights from Finland and Sweden

2017

This paper explores citizen participation in Swedish and Finnish regulatory processes for final disposal of spent nuclear fuel (SNF). Finland and Sweden are considered the most advanced worldwide in term of SNF disposal plans. Our aim is to analyze the institutional waste management frameworks, focusing on the role of civil society organizations (CSOs); how lay-people and civil society organizations have been able to participate and contribute to radioactive waste licensing processes; and the nature of radioactive waste risk debates. We review official documents of the waste companies and nuclear safety authorities, plus information from civil society organizations and laypeople. Our theore…

Does corn market uncertainty impact the US ethanol prices?

2018

The growing interest in biofuel as a green energy source has intensified the linkages between corn and ethanol markets, especially in the United States that represents the largest producing and exporting country for ethanol in the world. In this study, we examine the effect of corn market uncertainty on the price changes of US ethanol applying a set of GARCH-jump models. We find that the US ethanol price changes react positively to the corn market volatility shocks after controlling for the effect of oil price uncertainty. In addition, we document that the impact of corn price volatility on the US ethanol prices appears to be asymmetric. Specifically, only the positive corn market volatilit…

A comparison of the discrete and dimensional models of emotion in music

2010

The primary aim of the present study was to systematically compare perceived emotions in music using two different theoretical frameworks: the discrete emotion model, and the dimensional model of affect. A secondary aim was to introduce a new, improved set of stimuli for the study of music-mediated emotions. A large pilot study established a set of 110 film music excerpts, half were moderately and highly representative examples of five discrete emotions (anger, fear, sadness, happiness and tenderness), and the other half moderate and high examples of the six extremes of three bipolar dimensions (valence, energy arousal and tension arousal). These excerpts were rated in a listening experime…

Corporate business model transformation and inter-organizational cognition: the case of Nokia

2013

This article distinguishes between a firm’s corporate business model and business models of its various business units. Our aim is to provide new insights into how executives’ cognitive processes can influence corporate business model transformation decisions. We focus especially on top managers’ recognition of inter-organizational cognitions, that is, such cognitions about the firm and its businesses that are shared by the top managers and stakeholders of the firm in the industries and communities where it operates. We support our theoretical work with an historical case study of Nokia’s corporate business model transformation between 1990 and 1996, which proved highly successful. We find …

Riconfigurare i territori metroplitani. Forme di urbanizzazione e fenomeni di pressione insediativa sui sistemi di interesse naturale in Sicilia

2018

The consumption of the soil due to urbanization it is a phenomena already for many years under observations, but of which only the scientific environment has noticed the elevated environmental impact progress. From a disciplinary point of view, is possible to identify a line of research focusing on the analysis and identification of new morphologies of urbanization and on the interaction among different settlement patterns coexisting in a specific context. This reading complements with the scientific production about the forms of settlement pressure on environmental systems, producing change and deterioration on natural ecosystems and loss of biodiversity. A necessary reference for this lin…

tale percentuale se considerata per i comuni costieri supera il 75% del territorio urbanizzato. Nel caso dei sistemi naturali i fenomeni di pressione umana pesano su una situazione già critica data da una distribuzione puntuale delle aree protette. Il livello di frammentazione e isolamento di queste aree rischia di peggiorare. In Sicilia l'assenza di strumenti di valutazione ambientale e lo scollamento tra pianificazione urbana e regionale e pianificazione settoriale hanno determinato un inadeguato livello di controllo della pressione umana sui sistemi ambientali. Riguardo a questo quadro generale il presente documento presenta un chiarimento e una riformulazione del rapporto di reciprocità tra ambiente edificato e territorio aperto con l'obiettivo di individuare possibili strategie per gestire i fenomeni di dispersione urbana nel contesto metropolitano obiettivo principale delle politiche territoriali europee e di molte politiche nazionali degli Stati membri.Settore ICAR/20 - Tecnica E Pianificazione UrbanisticaIl consumo del suolo a causa dell'urbanizzazione è un fenomeno già da molti anni sotto osservazione ma di cui solo l'ambiente scientifico ha notato l'elevato impatto ambientale. Da un punto di vista disciplinare è possibile individuare una linea di ricerca incentrata sull'analisi e l'identificazione di nuove morfologie dell'urbanizzazione e sull'interazione tra i diversi modelli insediativi che coesistono in un contesto specifico. Questa lettura si integra con la produzione scientifica sulle forme di pressione insediativa sui sistemi ambientali producendo cambiamento e deterioramento degli ecosistemi naturali e perdita di biodiversità. Un riferimento necessario per questa linea sono gli studi sui processi di frammentazione (lineare concentrato misto) e quelli sulla segregazione degli habitat naturali e seminaturali (protetti o non protetti). Tali riferimenti si combinano con le analisi condotte sul processo di sostituzione dei sistemi naturali con l'ecomosaico artificiale. Lo stato dell'urbanizzazione in Sicilia è interessato dal fenomeno della dispersione urbana che a partire dagli anni Settanta ha contribuito fortemente a plasmare il territorio regionale sia dal punto di vista fisico che funzionale. Tale fenomeno ha interessato principalmente le aree marginali intorno alle aree metropolitane dove i terreni consumati dagli insediamenti a bassa densità abitativa rappresentano il 42% dell'intero territorio urbanizzatoSettore ICAR/21 - Urbanistica

Intellectual property rights and economic growth

2015

Striving for greater economic growth, requires a great understanding of the underlying factors. One of the factors may be the intellectual property rights and the level of its protection. Whether it is and how does it behave are the questions answered by this thesis. The theoretical framework comes mainly from the Schumpeterian growth model. The empirical methodology uses GMM in order to obtain reliable results. The level of intellectual property rights protection in the country does seem to have a positive effect on the country’s growth rate. Furthermore it seems that the relation is non-linear: The incremental changes are different between low and high starting levels of the IPR protectio…

E-BUSINESS MODEL: A CONTENT BASED TAXONOMY OF LITERATURE

2012

The rapid worldwide growth of e-commerce and the resulting great interest on the digital business, caused a proliferation of contributes by academics and practitioners, that identified by different points of view, the fundamental concepts, codes and functions of e-business models. The quantity and the variety of approaches adopted made the concept of e-business model fuzzy and vague, with little consensus about its ontology and definition. The relevance of the topic asserts a claim for the classification of contributions as a first step to a general definition of the concept of e-business model. This paper provides an integrated literature review of contemporary academic writings to ascerta…

MOCSE Centered on Students: Validation of Learning Demands and Teacher Support Scales

2020

Based on The Educational Situation Quality Model (MOCSE, acronym in Spanish) framework, the primary objective of this study is to test the factorial validity and reliability of two MOCSE measure instruments referred to the preactional-decisional phase, specifically to learning demands and teacher supports perceived by students to overcome such demands in the classroom context. The participants were 357 Spanish undergraduate students. The data obtained by exploratory and confirmatory factor analyses revealed that the “Learning Demands Scale” (MOCSE-LDS) has a two-factor structure: perceived desirability and feasibility of demands. The data also revealed that the “Teacher Support Questionnair…
