Ostacoli e determinanti dell’innovazione: un’analisi sulle imprese siciliane di successo

2010

Questo lavoro intende contribuire ad ampliare la precedente indagine Res sull’innovazione in Sicilia, soffermandosi in particolare ad analizzare i principali fattori di ostacolo alla realizzazione di innovazioni. In generale, le nostre elaborazioni mettono in evidenza l'esistenza di elevati livelli di percezione delle barriere territoriali esterne imposte dalle carenze del contesto (infrastrutture, pubblica amministrazione, servizi alle imprese etc.). Tuttavia, le nostre stime fanno emergere l’importanza delle barriere economiche e delle barriere relazionali nel determinare soprattutto le innovazioni di processo. Un altro risultato della ricerca sottolinea l’elevato grado di interdipendenza…

Convergent results from experimental and theoretical DFT studies of the intramolecular rearrangement of Z-hydrazones of 3-acetyl-1,2,4-oxadiazoles

2004

A combined kinetic and theoretical study of the monocyclic rearrangements of heterocycles (MRH) has been carried out. The interconversion of the Z-hydrazone of 3-benzoyl-5-phenyl-1,2,4-oxadiazole into the corresponding triazole has been experimentally investigated in dioxane/water in the pS(+) range 5.5(5)-13.9. The uncatalyzed region has been examined at the DFT level using a model system formed by the Z-hydrazone of 3-formyl-1,2,4-oxadiazole and one or two water molecules. The environmental effect of the solvent has been emulated using a continuum model (COSMO) approach. The kinetic data suggest a concerted process where the magnitude of the activation barrier is determined by the interpl…

Customers’ QR Code Usage Barriers in a Brick-and-Mortar Store : A Qualitative Study

2023

The purpose of this study is to explore the factors that hinder customers from utilizing QR codes when they visit brick-and-mortar (B&M) stores. The research was conducted at a Finnish fashion retailer, where three types of QR codes were displayed for customers to use. In order to identify the barriers that customers face, two different sets of data were collected and analyzed: open-ended survey data (n = 101) and interview data (n = 16). The findings showed two main categories of barriers,customer and company related, with seven sub-barriers. The customer-related barriers included lack of interest in QR codes, user-related usage issues, desire for a device-free B&M store, and dislike towar…

Panama and the WTO: new constitutionalism of trade policy and global tax governance

2017

"Corrigendum" in Review of International Political Economy, 24(4), p. 738 (DOI: 10.1080/09692290.2017.1332547). Tax havens and tax flight have lately received increasing attention, while interest toward multilateral trade policies has somewhat diminished. We argue that more attention needs to be paid exactly to the interrelations between trade and tax policies. Drawing from two case studies on Panama's trade disputes, we show how World Trade Organization (WTO) rules can be used both to resist attempts to sanction secrecy structures and to promote measures against tax flight. The theory of new constitutionalism can help to explain how trade treaties can 'lock in' tax policies. However, our c…

Krytyka „kultury wykluczenia” w nauczaniu papieża Franciszka

2017

Na przestrzeni wieków rozumienie problemu wykluczenia było niestateczne. Zawsze jednak pozostawało w silnym związku z epoką, kulturą, standardem życia ludzi. Przeobrażały się także poglądy dotyczące oceny moralnej działań powodujących wykluczenie społeczne. Dosyć często wykluczonych postrzegano jako „pasożytów porządnych społeczeństw”. W wielu przypadkach ekskluzję interpretowano jako wybraną drogę życia wielu mędrców. Niejednokrotnie w odniesieniu do tego samego typu społeczeństwa stosowane są odmienne, konkurujące ze sobą, modele wyjaśniania przyczyn wykluczenia i sposoby konceptualizacji tak zwanej kultury wykluczenia. Jeśli ograniczyć się tylko do społeczeństwa funkcjonującego w ramach …

Exercise and lactate production:implication in fatigue and in brain signaling

2016

More than two hundred years after its discovery, lactate still remains an intriguing molecule. Considered for a long time as a waste product of metabolism and the culprit behind muscular fatigue, it was then recognized as an important fuel for many cells. In particular, in the nervous system, it has been proposed that lactate, released by astrocytes in response to neuronal activation, is taken up by neurons, oxidized to pyruvate and used for synthesizing acetyl-CoA to be used for the tricarboxylic acid cycle. More recently, in addition to this metabolic role, the discovery of a specific receptor prompted a reconsideration of its role, and lactate is now seen as a sort of hormone, even invol…

Transcriptional Control of Quality Differences in the Lipid-Based Cuticle Barrier in Drosophila suzukii and Drosophila melanogaster

2020

Cuticle barrier efficiency in insects depends largely on cuticular lipids. To learn about the evolution of cuticle barrier function, we compared the basic properties of the cuticle inward and outward barrier function in adults of the fruit flies Drosophila suzukii and Drosophila melanogaster that live on fruits sharing a similar habitat. At low air humidity, D. suzukii flies desiccate faster than D. melanogaster flies. We observed a general trend indicating that in this respect males are less robust than females in both species. Xenobiotics penetration occurs at lower temperatures in D. suzukii than in D. melanogaster. Likewise, D. suzukii flies are more susceptible to contact insecticides …

Mapping knowledge and experience about sport psychology consulting among Finnish premier football coaches

2016

Mikola, Noora 2016. "Mapping knowledge and experience about sport psychology consulting among Finnish premier football coaches” Sport and Exercise Psychology master's thesis. The Faculty of Sport and Health Sciences, University of Jyväskylä. 50 p. Background: Perceptions of sport psychology consulting in Finnish premier football have not been studied before. The current study was inspired by two earlier studies made in England by Pain and Hardwood (2004) and in Sweden by Johnson, Andersson and Fallby (2011) and was done in co-operation with the Football Association of Finland. The purpose of the study was to examine knowledge and experience about sport psychology consulting among Finnish pr…

A new methodology to estimate deformation of longitudinal safety barriers

2013

The correct sizing of storage areas in the port areas is aimed to optimizing the management of intermodal transport and to ensure efficiency and functionality to the entire port system. In this paper is proposed a simulation model for design the port storage areas taking into account many parameters like: the service time, the randomness of the arrivals process, the storage capacity in terms of TEU that can be stored (and handled) in the unit of time. The capacity of the terminal warehouse is determined by the interrelation between fixed and static parameters in the short period which are: i) the extension of the storage area; ii) the height of the overlapping batteries of container (define…
