Comparative transcriptomics of albino and warningly‐coloured caterpillars
2021
Abstract Coloration is perhaps one of the most prominent adaptations for survival and reproduction of many taxa. Coloration is of particular importance for aposematic species, which rely on their coloring and patterning acting as a warning signal to deter predators. Most research has focused on the evolution of warning coloration by natural selection. However, little information is available for color mutants of aposematic species, particularly at the genomic level. Here, I compare the transcriptomes of albino mutant caterpillars of the aposematic wood tiger moth (Arctia plantaginis) to those of their full sibs having their distinctive orange‐black warning coloration. The results showed >29…
UTTAL AV S2-FINSKA MED FOKUS PÅ SVENSKSPRÅKIGA TALARE
2016
I undersökningen analyseras 11 inföddliknande S2-talares uttal av finska. Sex av talarna har finlandssvenska som S1, fem av talarna har sverigesvenska, tyska, franska, ryska resp. spanska som S1. Talarnas uttal undersöktes dels genom ett test med finskspråkiga lyssnare (n=93), dels genom att S2-talarnas uttal jämfördes akustiskt med uttalet hos talare med finska som S1. Vidare jämfördes de finlandssvenska talarnas uttal av finska och svenska. Resultaten visar att finlandssvenska talare skiljer sig som grupp från infödda finskspråkiga talare och från talare med ett annat S1 än finlandssvenska. De flesta finlandssvenskar bröt mycket svagt. Stavelselängderna och intonationen i långa ord orsaka…
Nyfinlandssvenskarna : språklig identitet hos invandrare som integrerat sig i det finska samhället på svenska
2014
Tutkimuksen tarkoituksena on saada tarkempaa tietoa maahanmuuttajien kielellisestä identiteetistä. Keskityn tutkimuksessani maahanmuuttajiin, jotka ovat oppineet valtakunnallisen vähemmistökielen ruotsin, joka on heidän sijoituspaikkakunnallaan enemmistökielen asemassa. Tutkimuksen empiirinen materiaali koostuu teemahaastatteluista. Haastateltavina olleet 5 maahanmuuttajaa (iältään 20 – 54-vuotiaita) osallistuivat henkilökohtaisiin teemahaastatteluihin asuin tai työpaikkakunnallaan. Kaksi haastateltavista on tullut Suomeen pakolaisena 1990-luvulla, 2 perhesyistä ja 1 työnantajan lähettämänä. Erilaiset taustat sekä maassaoloaikojen eroavaisuudet (3-22 vuotta) antavat mahdollisuuden tarkastel…
Automatic surrogate modelling technique selection based on features of optimization problems
2019
A typical scenario when solving industrial single or multiobjective optimization problems is that no explicit formulation of the problem is available. Instead, a dataset containing vectors of decision variables together with their objective function value(s) is given and a surrogate model (or metamodel) is build from the data and used for optimization and decision-making. This data-driven optimization process strongly depends on the ability of the surrogate model to predict the objective value of decision variables not present in the original dataset. Therefore, the choice of surrogate modelling technique is crucial. While many surrogate modelling techniques have been discussed in the liter…

Évolutions récentes de l'agriculture française. Analyse géographique des tendances régionales et de la mise en place d'un nouveau dispositif d'aménag…
2005
The recent transformations in French agriculture and the emergence of the concept of sustainable development in the last decade have pushed politicians to defining new measures, of which most concern agriculture. The analysis of agricultural systems leads nowadays to studies on interactions with the physical, economical or social environment. The subject of this thesis is related to this context. Firstly, we propose to analyze the recent evolutions in French agriculture, particularly in the last mandate during which the most radical transformations occurred. It is of particular interest to identify, besides the general situation of French agriculture, the differences in evolution between th…
Management diversification increases habitat availability for multiple biodiversity indicator species in production forests
2022
Context Forest biodiversity is closely linked to habitat heterogeneity, while forestry actions often cause habitat homogenization. Alternative approaches to even-aged management were developed to restore habitat heterogeneity at the stand level, but how their application could promote habitat diversity at landscape scale remains uncertain. Objectives We tested the potential benefit of diversifying management regimes to increase landscape-level heterogeneity. We hypothesize that different styles of forest management would create a diverse mosaic of forest habitats that would in turn benefit species with various habitat requirements. Methods Forest stands were simulated under business-as-usua…
CIRCULAR PROCESSES FOR A NEW URBAN METABOLYSM: THE ROLE OF MUNICIPAL SOLID WASTE IN THE SUSTAINABLE REQUALIFICATION
2014
Through this paper we present the first results of a research combining the management problem of Municipal Solid Waste to the requalification of built environment. The goal of this research is to mitigate the vulnerability of territory and urban heritage and to transform a problem into opportunities. Above all, we have paid attention to several exemplifying cases of Italian territory: suburbs of large towns, historical centres, small centres (and, in particular, those with a strong historical connotation). Their features are, at the same time, restrictions and challenges for designing new compatible systems that can contribute to the requalification of urban landscape recovering spaces wit…
The Graffiti Storyline and Urban Planning : Key Narratives in the Planning, Marketing, and News Texts of Santalahti and Hiedanranta
2018
This article regards urban planning as a form of storytelling and argues that there is significance in whose stories and which storylines are acknowledged to belong to the narrative fabric of a place and how the stories of future districts are communicated to the public through narratives during a planning project. My focus is on the storyline that follows the activity of graffiti culture in the two case areas of Santalahti and Hiedanranta (located in the city of Tampere in Finland) during these areas’ phases of transition created during the redevelopment of former industrial areas into residential districts. In my discursive analysis I identify key narratives that recur in planning, market…
ABBA, IKEA och köttbullar : kulturundervisningen i läroböckerna avsedda för årskurs sju i B-svenska
2014
Tutkimuksemme tarkoituksena on selvittää, kuinka ruotsalainen kulttuuri Ruotsissa ja Suomessa esitellään seitsemännen luokan B-ruotsin oppikirjoissa. Lisäksi tarkastelemme, eroavatko oppikirjojen tavat esittää kulttuuria toisistaan sekä vertailevatko kirjat näitä kahta kulttuuria keskenään. Selvitämme myös noudattavatko oppikirjat nykyisen opetussuunnitelman asettamia tavoitteita kulttuurin suhteen. Tutkimusaineistonamme ovat oppikirjat Megafon 1 (2012) ja Pågång 7 (2011). Jaoimme kulttuurielementit yhdeksään eri kategoriaan, jotka ovat1) musiikki, 2) kirjallisuus, 3) elokuvat, 4) urheilu, 5) maantieto ja historia, 6) yhteiskunta ja arkielämä, 7) ruoka, 8) juhlat ja perinteet ja 9) muut.
