Soil organic carbon storage capacity of old and modern wheat varieties
2022
Despite the possible mitigation of carbon emissions by favoring carbon transfer to terrestrial carbon sinks, little is knownabout the capacity of different crop genotypes to enhance soil carbon sequestration. We hypothesize that carbon sequestrationpotential linked to old wheat varieties (released before 1960) is higher than the one linked to modern ones while old varietiesare known to develop bigger and deeper root systems. Moreover, modern varieties are often cultivated using syntheticchemical inputs known to modify soil carbon dynamics. We conducted a field experiment by cultivating four modern andfour old wheat varieties, with and without chemical inputs (nitrogen, herbicide and fungici…
Carbon storage in soils by ancient and modern wheat varieties
2022
Les émissions anthropiques de gaz à effet de serre sont le principal moteur du changement climatique. Le plan Climat, issu de la COP 21 tenue à Paris en 2015, vise à atteindre la neutralité carbone à l'horizon 2050. Pour atteindre cette neutralité carbone, les gaz à effet de serre doivent d'abord être stabilisés, puis fortement réduits au cours du siècle prochain. Dans cette dynamique, l'initiative « 4 pour 1000 » fixe comme objectif d'atteindre un taux de croissance annuel du stock de carbone dans les sols de 0,4% par an. Ce stockage additionnel devrait compenser les émissions de CO2 dans l'atmosphère liée aux activités humaines. Les sols agricoles sont identifiés comme un compartiment de …
Il ruolo del contatto tra varietà tedesche e romanze nella costruzione «verbo più locativo»
2016
In this article we examine some effects of language contact in the multilingual province of Trento, where Romance and Germanic varieties have been in contact for centuries. We focus on the syntax of phrasal verbs (e. g. ‘go out’, ‘get away’) in Trentin, a Romance dialect group, in Fassan, a Rhaeto-romance variety, and in Cimbrian, a German(ic) minority language. In particular, we deal with two word order phenomena which might be attributed to contact with the more prestigious or widespread varieties spoken in the area: (i) in some Fassan phrasal verbs we find the order «Verb – XP – Locative element», which resembles the German order; (ii) in Cimbrian various syntactic positions are possible…
Vārdu savienojumu variācijas angļu valodas variantu tīmekļa korpusos
2020
Kopš pasaulē internets ir kļuvis aizvien pieejamāks, palielinājusies arī saziņa starp cilvēkiem visā pasaulē. Šāda informācijas apmaiņa var izraisīt globalizācijas efektu valodās vai valodu variantos, it īpaši valstiskajā līmenī. Neraugoties uz to, dažādi pētnieki ir analizējuši dažādās pasaules valstīs lietotās angļu valodas variāciju atšķirības, nevis līdzības. Tādējādi šā, uz korpusu balstītā pētījuma mērķis ir analizēt kolokācijas, pamatojoties uz izvēlēto lietvārdu sarakstu, kas veidots, izmantojot četras nacionālās angļu valodas variantus – amerikāņu, austrāliešu, britu un kanādiešu. Analīze tika veikta divos korpusos – Corpus of Global Web-Based English (GloWbE) un Corpus of Four Nat…
Nitrogen uptake and nitrogen fertilizer recovery in old and modern wheat genotypes grown in the presence or absence of interspecific competition
2015
Choosing genotypes with a high capacity for taking up nitrogen (N) from the soil and the ability to efficiently compete with weeds for this nutrient is essential to increasing the sustainability of cropping systems that are less dependent on auxiliary inputs. This research aimed to verify whether differences exist in N uptake and N fertilizer recovery capacity among wheat genotypes and, if so, whether these differences are related to a different competitive ability against weeds of wheat genotypes. To this end, 12 genotypes, varying widely in morphological traits and year of release, were grown in the presence or absence of interspecific competition (using Avena sativa L. as a surrogate wee…

From state-owned smokestacks to post-industrial dreams : The Finnish government in business, 1970–2010
2020
While state-owned enterprises (SOEs) used to be considered obsolete tools for governmental intervention in the economy, in recent years governmental intervention in the business sector has re-emerged as a topic of debate. However, scholarship on the changes in and the modernisation of the SOE model is limited. In this article, we examine how the Finnish state’s ownership policy adapted to the requirements of economic globalisation between the 1970s and the 2010s. We show that the attitude towards globalisation was pragmatic and aimed at safeguarding the competitiveness of domestic companies. The state-owned company system was gradually adapted to meet new needs, losing most of its original …
Modal Consequence Relations Extending S4.3: An Application of Projective Unification
2016
We characterize all finitary consequence relations over $\mathbf{S4.3}$ , both syntactically, by exhibiting so-called (admissible) passive rules that extend the given logic, and semantically, by providing suitable strongly adequate classes of algebras. This is achieved by applying an earlier result stating that a modal logic $L$ extending $\mathbf{S4}$ has projective unification if and only if $L$ contains $\mathbf{S4.3}$ . In particular, we show that these consequence relations enjoy the strong finite model property, and are finitely based. In this way, we extend the known results by Bull and Fine, from logics, to consequence relations. We also show that the lattice of consequence relation…
Teksty farmaceutyczne i dyskurs farmaceutyczny : definicje, specyfika i krótki przegląd pola badawczego
2020
This chapter aims to familiarize readers with the specificity of pharmaceutical discourse, including its spoken and written text varieties. I paid particular attention to two issues. Firstly, pharmaceutical discourse and pharmaceutical texts are often classified by researchers into broader category of medical or biomedical discourse. Second, pharmaceutical discourse is not autonomous as it is also permeated with medical, legal, academic and other discourses. Next, pharmaceutical discourse was described in greater detail using descriptive models proposed by Bhatia (2004) and Gunnarson (2009). Finally, a selection of research studies, including linguistic and interdisciplinary ones, conducted…
Board structures, liberal countries, and developed market economies. Do they matter in environmental reporting? An international outlook
2019
This is the pre-peer reviewed version of the following article: Board structures, liberal countries, and developed market economies. Do they matter in environmental reporting? An international outlook, which has been published in final form at: https://doi.org/10.1002/bse.2275. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Use of Self-Archived Versions. Previous empirical evidence has shown the effect of most corporate governance mechanisms on corporate social responsibility and environmental disclosure. However, there is scant empirical evidence that examines the influence of liberal countries, developed market economies, and board s…
