Tourism statistics and unobserved tourism: empirical evidences in Sicily

2013

Despite its strategic importance, accurately measuring visitor attendance has been a challenging and problematic exercise for tourism managers for decades. Consequently, the primary aim of tourism statistics of accurately quantify tourism flows has been only partially achieved; indeed at a lower territorial scale tourism statistics appear less precise and accurate. The aim of this paper is: to introduce the concept of unobserved tourism, by highlighting the main limits of official statistical systems (with a special focus on the European statistical system on tourism statistics; to formalize a theoretical model in which tourism nights and trips in a given destination are decomposed into obs…

Progress towards sustainable agriculture – Drivers of change

2021

Sustainable Development Goal (SDG) 2 calls for global action to “end hunger, achieve food security and improved nutrition, and promote sustainable agriculture”. Meeting this challenge requires global partnerships to support more productive, nutritious and equitable food systems, while helping to conserve environmental resources and reduce the greenhouse gas (GHG) emissions responsible for global climate change. The Food and Agriculture Organization of the United Nations (FAO) offers a global vision for a more sustainable agriculture that encompasses economic, social and environmental dimensions of food and agriculture systems. This technical study examines the key factors driving changes in…

OUTSTANDING DEVELOPMENTS IN THE ROMANIAN BANKING SYSTEM

2011

The Romanian banking system, after 1990, went through several stages in order to adapt to a new economic context, respectively to the necessary adjustment to the transition from centralized economy to market economy, and then, after the year 2000, adapting to meet the European Union’s membership requirements, and later, after 2007, adapting to adopt the euro currency. These events to which the Romanian banking system must adapt are known events. To which, however, join contingencies related to the onset and manifestation of the international financial crisis, events with direct impact on the banking system in Romania that determined changes both in the banking regulations, and in the struct…

Quality of Inclusive Educational System for Work with Students with Autism Different Needs in Italy

2015

The need for realization of inclusive education, which is the basis of a sustainable education, will require new challenges in the Education System. The system used in Italy can be used as an example. Italy passed avant-garde laws concerning the integration and inclusion of special needs students into the general school system already more than thirty years ago, in the 1970s. However, even after all this time and experience, there are still unresolved problems, which testifies to the complexities of the matter. This research offers an insight into the quality of the existing Italian inclusive education system specifically in relation to students with autism. Thereby it hopes to provide educ…

The use of energy in the Mediterranean fishing catching sector. A Sicilian perspective

2010

This article address an issue of paramount importance in the Mediterranean area, that is the efficient use of energy and sustainability of fishing sector. A recent study concerning the situation of Fishery and Aquaculture in Sicily highlighted that the Sicilian fishing system requires a bigger amount of energy than the typical Italian or European situation, in order of getting the product available to the market. On the other hand this involves an higher level of environmental pollution, for a given quantity of catch. One of the main findings is that there is a need for a clear, scientifically-founded panorama of the situation and that further studies should be undertaken to provide fishing…

The use of bark of Scots Pine in environmental impact assessment of cement and lime dust

2016

Analizie poddano korę sosny zwyczajnej znajdującej się pod presją zanieczyszczeń alkalicznych cementowni Chełm. Na podstawie wodnych wyciągów z kory określono zasięg oddziaływania pyłów cementowo-wapienniczych na środowisko. Zależności pomiędzy pHH2O kory a odległością od źródła emisji pyłów badano metodą analizy regresji i korelacji liniowej. Wyniki badań odnoszono do wyników uzyskanych na leśnej powierzchni kontrolnej - wolnej od zanieczyszczeń alkalicznych. W miarę oddalania od źródła zanieczyszczeń opad pyłów cementowo-wapienniczych obniża się, co jest zrozumiałe, i znajduje potwierdzenie w zmiennych wartościach pHH2O kory sosny. Najsilniej odnotowano presję w kierunku NE, ES i SW, gdzi…

Badania nad potencjalnym wykorzystaniem pluskwiaków różnoskrzydłych (Hemiptera: Heteroptera) w bioindykacji i monitoringu przyrodniczym

2023

This paper presented the results of the studies on true bugs (Hemiptera: Heteroptera) alongside evaluating their potential usefulness in biomonitoring and bioindication. The studies were carried out in May and August of 2017. Three research sites situated at various distances from the full-scale plants (Grupa Azoty Zakłady Azotowe Kędzierzyn SA, Zakłady Chemiczne Petrochemia-Blachownia SA, Zakłady Koksownicze ArcelorMittal Poland Zdzieszowice) and the control area out of reach of the emission of chemical pollutants, i.e. the meadows in the Chrząstowice area of Natura 2000, have been selected for studies. All studied meadows were classified within the Molinio-Arrhenatheretea class. As a resu…

Identification and structural characterization of O-beta-ribosyl-(1"----2')-adenosine-5"-phosphate in yeast methionine initiator tRNA.

1990

We report in this paper on the complete structure determination of the modified nucleotide A*, now called Ar(p), that was previously identified in yeast methionine initiator tRNA as an isomeric form of O-ribosyl-adenosine bearing an additional phosphoryl-monoester group on its ribose2 moiety. By using the chemical procedure of periodate oxidation and subsequent beta-elimination with cyclohexylamine on mono- and dinucleotides containing Ar(p), we characterized the location of the phosphate group on the C-5" of the ribose2 moiety, and the linkage between the two riboses as a (1"----2')-glycosidic bond. Since the structural difference between phosphatase treated Ar(p) and authentic O-alpha-rib…

3'-Arylazido-beta-alanyl-2-azido ATP, a cross-linking photoaffinity label for F1ATPases.

1989

Abstract The synthesis of the 3′-arylazido-2-azido ATP derivative 3′-O-{3-[N-(4-azido-2-nitrophenyl)-amino]propionyl}2-azido-adenosine 5′-triphosphate (2,3′-DiN3ATP) is described. The bifunc­ tional photoreactive ATP analog is characterized spectroscopically. Photoaffinity labeling of F, ATPase from Micrococcus luteus by this analog results in the inactivation of the enzyme and in the formation of higher molecular weight cross-links,
