Saab outstands in the history of the Finnish car manufacturing. This is not only due to that these cars have been manufactured in Finland more than other passenger vehicles altogether. Finns also have a special emotional attachment to the “Finnish Saabs”. Findings from previous studies show that consumers connect cars well to the origin of the brand (COB). They are however rarely aware of the Country of Manufacturing (COM). Domestic brands are often popular in the COB, but research from situations in which the domestic origin is limited to the COM is rare. The case of this study is a phenomenon, in which the products origin is two dimensional and divided into domestic COM and foreign COB. The aim is to understand the phenomenon’s effect on consumer behavior. The research problem is approached with two sub questions: • Which country do consumers perceive as the origin country of the car? • What is the role of this origin in the consumers’ product perception and purchasing decision of the car? The theoretical framework of this study applies previous findings of two areas of interest: Country of Origin effect and Consumer Ethnocentrism. This is followed by feasibility studies that present and discuss the history and current state of Finnish car manufacturing. Based on the findings of earlier stages of the study, the role of the domestic COM on consumer behavior is presumed high. This expectation is confirmed by the experts and also by the first consumer respondent, who states domestic origin having been the main motivation to his car choice. All further consumer respondents do however not connect Saab to the home country, but discuss it as a Nordic car. This unexpected finding means that they do not perceive the origin to be neither the COM nor COB, but a geographical area that includes both countries. In other words, consumers have widened their in-group in a way that is in this thesis explained with reference group theory. The consumers’ perceived origin of the car is in this research found to be an important factor to the consumers’ product perception and purchasing decision. Being fit for the yields of the local environment is discovered to have been the most important factor to Finnish consumers purchasing choice of a Saab and the Nordic origin has been an indicator of this fit to them.

Many arthropods exhibit behaviours precursory to social life, including adult longevity, parental care, nest loyalty and mutual tolerance, yet there are few examples of social behaviour in this phylum. The small carpenter bees, genus Ceratina, provide important insights into the early stages of sociality. I described the biology and social behaviour of five facultatively social species which exhibit all of the preadaptations for successful group living, yet present ecological and behavioural characteristics that seemingly disfavour frequent colony formation. These species are socially polymorphic with both / solitary and social nests collected in sympatry. Social colonies consist of two adult females, one contributing both foraging and reproductive effort and the second which remains at the nest as a passive guard. Cooperative nesting provides no overt reproductive benefits over solitary nesting, although brood survival tends to be greater in social colonies. Three main theories explain cooperation among conspecifics: mutual benefit, kin selection and manipulation. Lifetime reproductive success calculations revealed that mutual benefit does not explain social behaviour in this group as social colonies have lower per capita life time reproductive success than solitary nests. Genetic pedigrees constructed from allozyme data indicate that kin selection might contribute to the maintenance of social nesting -, as social colonies consist of full sisters and thus some indirect fitness benefits are inherently bestowed on subordinate females as a result of remaining to help their dominant sister. These data suggest that the origin of sociality in ceratinines has principal costs and the great ecological success of highly eusociallineages occurred well after social origins. Ecological constraints such as resource limitation, unfavourable weather conditions and parasite pressure have long been considered some of the most important selective pressures for the evolution of sociality. I assessed the fitness consequences of these three ecological factors for reproductive success of solitary and social colonies and found that nest sites were not limiting, and the frequency of social nesting was consistent across brood rearing seasons. Local weather varied between seasons but was not correlated with reproductive success. Severe parasitism resulted in low reproductive success and total nest failure in solitary nests. Social colonies had higher reproductive success and were never extirpated by parasites. I suggest that social nesting represents a form of bet-hedging. The high frequency of solitary nests suggests that this is the optimal strategy when parasite pressure is low. However, social colonies have a selective advantage over solitary nesting females during periods of extreme parasite pressure. Finally, the small carpenter bees are recorded from all continents except Antarctica. I constructed the first molecular phylogeny of ceratinine bees based on four gene regions of selected species covering representatives from all continents and ecological regions. Maximum parsimony and Bayesian Inference tree topology and fossil dating support an African origin followed by an Old World invasion and New World radiation. All known Old World ceratinines form social colonies while New World species are largely solitary; thus geography and phylogenetic inertia are likely predictors of social evolution in this genus. This integrative approach not only describes the behaviour of several previously unknown or little-known Ceratina species, bu~ highlights the fact that this is an important, though previously unrecognized, model for studying evolutionary transitions from solitary to social behaviour.

The natural abundance of the N-heterocycle containing compounds has pushed the synthetic community toward the invention of new synthetic methods that result in the structural diversity of N-heterocycles. Among this, is the efficient and highly selective diamine mediated asymmetric lithiation process. Amongst the diamine chiral ligands, (-)-sparterine, which is a naturally occurring alkaloid proved to be an efficient one. Many successful, good yielding and highly selective lithiation reactions have been accomplished with the mediation by this chiral diamine base. Although, there are some examples of experimental and theoretical mechanistic studies in the literature, there is a lack of detailed understanding as to how it exactly induces the chirality. In this thesis is described a systematic investigation of how (-)-sparteine influences the stereoselectivity in the course of asymmetric lithiation reaction. This led us to the establishment of the function of A-ring’s β-CH2 effect and D-ring effect. Consequently, the importance of the A-ring and D-ring portions of (-)-sparteine in the stereoselectivity is unraveled. Another part of this thesis deals with the asymmetric lithiation of BF3-activated N,N- dimethylaminoferrocene in the presence of (1R, 2R)-N1,N2-bis(3,3-dimethylbutyl)-N1,N2-dimethylcyclohexane-1,2-diamine ( a (R,R)-TMCDA surrogate) with i-PrLi. Computational findings were in full accord with the experimental observations. Subsequently, the theoretically provided insights into the mechanism of the reaction were exploited in computational design of a new ligand. Unfortunately, the outcome of this design was not experimentally robust and an updated approach towards a successful design was explained.

Geography has long been a predominantly visual discipline, but recent work in geography has sought to explore the multisensory, embodied, emotional and affective dimensions of people’s relations with places. One way to engage this type of exploration is through the use of sound walks: walks along a specified route accompanied by a soundtrack (on headphones or stationary speakers) that conveys information, enacts a story, produces an ambience or atmosphere, or illuminates certain aspects of the environment through which the listener is walking. This thesis aims to show how geographers can benefit from using sound walks as thinking tools, representational tools and teaching tools. Drawing on my own experiences producing sound walks, I first examine the ways that sound walk production processes help generate productive geographical thinking for those producing sound walks (Chapter Two). The various stages of producing a sound walk require different skill sets, pose different challenges, and require different sorts of environmental awareness, and therefore present novel opportunities for developing geographical insights about specific places or spatial relations. Second, I focus on four experientially-oriented aspects of sound walks – using multiple senses, walking, contingency, and moments of interaction – to argue that sound walks can be useful representational tools for geographers, whether those creating sound walks subscribe to a representational or non-representational theory of knowledge (Chapter Three). The value of sound walks as representational tools is in the experience of ‘doing’ them. That is, audiences discover for themselves through interaction what is being represented, rather than having it delivered to them. The experiential elements of ‘doing’ sound walks recommend them as potentially helpful representational tools for geographers. Third, by examining the work of a small sample of fourth year “Advanced Geography of Music” students, I develop the argument that sound walks can be effective tools for teaching students and for creating circumstances for students to learn independently (Chapter Four). Sound walks have potential to be effective pedagogical tools because they are commensurate with several key pedagogical schools of thought that emphasise the importance of requiring students to engage actively with their environment using a combination of senses. The thesis demonstrates that sound walks are a worthwhile resource for geographers to use theoretically, representationally and pedagogically in their work. The next step is for geographers to put them into practice and realize this potential.

Nos études ont démontrées que la formation de la cicatrice et la guérison sont associées avec l’apparition de cellules de type myocytes cardiaques nestine(+) dans la région péri-infarcie. Présentement, l’étude examine le mécanisme, tel que l’hypoxie ou les hormones neuronales, possiblement impliqué dans leur recrutement et de dévoiler leur origine cellulaire. La présence de ces cellules a été détectée dans les coeurs infarcies d’une semaine et maintenue après neuf mois suite à une sujétion coronaire complète. Aussi, ces cellules de type myocytes cardiaques nestine(+) ont été observées dans le coeur infarci humain. L’hypoxie représente un événement prédominant suite à un infarctus de myocarde, mais l’exposition des rats normaux à un environnement hypoxique n’a pas pu promouvoir l’apparition de ces cellules. Autrement, l’infusion de l’agoniste -adrénergique non-sélectif isoprotérénol (ISO) dans les rats adultes Sprague-Dawley a augmenté la protéine nestine dans le ventricule gauche et a été associé avec la réapparition de cellules de type myocytes cardiaques nestine(+). Cela représente possiblement un effet secondaire suite à la nécrose des myocytes cardiaques par l’administration d’isoprotérénol. Dernièrement, on a identifié une sous-population de cellules nestine(+) dans le coeur normal du rat qui co-exprime les marqueurs de cellules cardiaques progénitrices Nkx-2.5 et GATA-4. Cette sous-population de cellules nestine/Nkx-2.5/GATA-4 pourrait représenter des substrats cellulaires qui puissent se différentier en cellules de type myocytes cardiaques nestine(+) suite à une ischémie. Mots clés: nestine, isoprotérénol, nécrose, cellule souche, cellule progénitrice, myocyte cardiaque

La présente étude a comme objectif d’analyser l’intégration linguistique des immigrants au marché du travail au Québec et les facteurs qui y sont associés. Nous le réalisons en examinant la place du français dans les pratiques linguistiques de la main-d’œuvre immigrée au travail. Nous constatons qu’au Québec, en 2007, environ la moitié des immigrants travaillent uniquement ou généralement en français, un quart a régulièrement recours à cette langue dans le cadre de son travail, alors que l’autre quart l’utilise occasionnellement ou ne l’utilise jamais au travail. Nos analyses permettent également d’estimer les effets bruts et nets des nombreux facteurs de l’usage du français au travail par les immigrants. Nous montrons que ce sont les facteurs linguistiques de l’entreprise, de l’entourage et du répondant lui-même qui se manifestent comme des déterminants importants de la langue de travail de celui-ci. Parmi les caractéristiques de l’entreprise, c’est la langue de sa haute direction qui, à travers des politiques d’embauche et des politiques internes, détermine en partie les pratiques linguistiques des travailleurs. La composition linguistique de l’entourage de l’immigrant au travail qui comprend son supérieur immédiat et ses collègues a, elle aussi, un impact important sur la langue employée au travail par celui-ci. Plus cet entourage est composé des personnes de langue maternelle française, plus le travailleur immigré utilisera cette langue au travail. Parmi les caractéristiques individuelles du répondant, sa langue d’études et ses compétences linguistiques ressortent. Les immigrants ayant une bonne connaissance du français l’emploient plus au travail que ceux en ayant une faible connaissance. En revanche, la connaissance de l’anglais a un impact négatif sur l’usage du français au travail. Selon nos analyses, parmi les facteurs non linguistiques qui sont associés significativement à la langue de travail des immigrants, il y a la localisation géographique de l’entreprise, l’origine des travailleurs immigrés, leur profession et l’âge à leur arrivée au Québec.
