The obstacle race to institutional change : the slow path to policy change of a coalition advocating for sexuality education in Norway
2019
Master's thesis Innovative governance and public management ME523 - University of Agder 2019 Developing schoolsexualityeducation policies is a complex matterdue to the controversial and politicized nature of sexuality. This thesisaims at understanding the development of institutional change in the presence of complex policy systems that involvemultiple actors in the policy process. To achieve this aim, itanalyses the actionsof an advocacy coalition that works to change sexuality education policies in Norway.The study adopts the Advocacy CoalitionFramework (ACF)for understanding the interconnections among the macro-level of the political and historicalcontext, the micro-level of the actor’s …
"Ihmiskunnalle ennen kokematon uhka" : ilmastonmuutoksen poliittiset merkitykset turvallisuus- ja puolustuspoliittisissa selonteoissa ja eduskunnassa…
2020
Artikkelissa tarkastellaan ilmastonmuutoksen turvallisuuspoliittisia merkityksiä Suomessa poliittisen kielenkäytön analyysimenetelmin. Turvallisuus- ja puolustuspolitiikassa uhkakuvat sekä niiden tärkeysjärjestys ja merkitys ovat poliittisen kamppailun kohteena. Käsitteellisellä tasolla esimerkiksi ilmastonmuutoksen turvallisuuspoliittinen merkitys määräytyy poliittisissa debateissa, joissa esitetään argumentteja politiikan linjanvedosta, ratkaisuista ja resursseista. Poliittiseen kielenkäyttöön, käsitteisiin ja argumentteihin keskittyvä analyysimenetelmä on tapa analysoida, missä merkityksissä ja yhteyksissä ilmastonmuutosta on parlamentaarisessa poliittisessa puheessa ja politiikkaa linja…
Le Currency board : les contraintes de financement et d'ajustement de la convertibilité intégrale
2000
The paper scrutinizes the consequences of the adoption of a currency board arrangement (CBA) by some emerging economies during the 1990s. Considering the justifications o f this choice and the different setting-up contexts, it focuses on the implications of a CBA on the financial system and the real economy. A high degree of liquidity of the banking system is required in the absence of a lender-of-last-resort, and the automatic money supply process strictly disciplines the fiscal policy. Monetary stability is restored; but in most o f these economies where capital markets are underdeveloped, CBA's rules make the domestic credit supply dependent on the ability o f the economy to maintain ove…
Weathering of low-density polyethylene grafted with itaconic acid in laboratory tests
2011
Polyethylene grafted with itaconic acid was subjected to weathering under laboratory accelerated conditions. The course of the photo-oxidative degradation process of that material was studied by FTIR spectroscopy both through quantitative measurements of changes in absorbance values at selected wave numbers and through measurements of surface area values for absorption bands which were separated by means of deconvolution. The use of both those procedures of quantitative determinations resulted in a general conclusion that the oxidation process was initiated from the very first moment of irradiation, and it produced ketones, acids, esters (intramolecular and of acetate type), peracids, peres…
Nuovi dati sull’espansione dell’occhione Burhinus oedicnemus in Sicilia. Una riflessione sulla citizen science
2023
New data on the expansion of the Eurasian Thick-knee Burhinus oedicnemus in Sicily. A consideration of citizen science.In this work, we collected records of Eurasian Thick-knee observa-tions in Sicily by using scientific literature, citizen science programs, and social networks as data sources. The aims of this work is creat-ing a complete and up-to-date dataset, which also includes the authors’ targeted research in the field. As compared with records previously reported in literature, the data collected here, which cover the last fif-teen years, show a clear expansion trend for the Eurasian Thick-kneein Sicily. About one third of these new records come from Facebook groups dedicated to bio…
AGGIORNAMENTO SULLA DISTRIBUZIONE DEL SUCCIACAPRE Caprimulgidae) IN SICILIA CAPRIMULGUS EUROPAEUS (Aves
2021
Caprimulgus europaeus In recent years Update on the distribution of breeding Nightjar in Sicily. there have been numerous observations of Nightjar in areas where it had never previously been observed. In some cases the reason may be a deeper exploration, but in other cases the possible explanation is the expansion of the species. However, it is quite interesting the change in the habitat by this species. The present paper provides an update of its status based on data collected in the fifteen years following the publication of the last Sicilian Atlas of breeding birds.
ESPANSIONE DELLA RONDINE MONTANA PTYONOPROGNE RUPESTRIS (SCOPOLI) IN SICILIA (Aves Hirundinidae)
2021
Expansion of the Eurasian Crag Martin Ptyonoprogne rupestris (Scopoli) in Sicily (Aves Hirun dinidae). Data collected during the last fifteen years on the distribution of the Eurasian Crag Martin in Sicily and the comparison with those recorded in literature show an expansion trend for this species. While in the newly colonized areas the nesting sites have been observed mainly on natural habitats, where its occurrence was previously recorded the species shows and adaptation to exploit also anthropogenic habitats, such as buildings or other infrastructures.
Are habitat loss, predation risk and climate related to the drastic decline in a Siberian flying squirrel population? A 15 year study
2014
To devise effective conservation actions, it is important to know which factors are associated with the population parameters of a declining population. Using mark–recapture methods, we estimated the annual population size, growth rate and survival probability of an ear-tagged flying squirrel population over a 15-year period in a 4,500 ha study area in western Finland. The species is considered vulnerable, but detailed knowledge concerning population sizes or trends is lacking. The population parameters and changes therein were regressed against habitat availability, an indicator of predation pressure, and mean winter temperature (an indicator of climate change), to reveal potential reasons…
