Since financial liberalization in the 1980s, non-profit maximizing, stakeholder-oriented banks have outperformed private banks in Europe. This article draws on empirical research, banking theory and theories of the firm to explain this apparent anomaly for neo-liberal policy and contemporary market-based banking theory. The realization of competitive advantages by alternative banks (savings banks, cooperative banks and development banks) has significant implications for conceptions of bank change, regulation and political economy.

Tutkimuksen tavoitteena oli selvittää kansainvälistymisteorioiden toimivuus laadittaessa kohdeyrityksen hankkimalle juustolaiteliiketoiminnalle kansainvälistymisstrategian linjaukset. Taustamateriaalina tutkittiin laajalti kohdeyrityksen näkökulmasta valittujen kansainvälistymisteorioiden esille tuomia kansainvälistymisen haasteita, edellytyksiä sekä toteuttamismuotoja. Lisäksi tutkittiin kohdeyrityksen juustolaiteliiketoiminnan historian aikana toteutuneet kansainvälistymisvaiheet ja verrattiin niitä vastaaviin kansainvälistymisteorioihin. Juustolaiteliiketoiminnan kansainvälistymistä varten haastateltiin juustoalan asiantuntijoita, juustoliiketoiminnan entisiä avainhenkilöitä sekä kohdeyrityksen johtoa ja hallituksen jäseniä. Juustomarkkinoiden laajuus ja houkuttelevuus sekä alan tärkeimmät kilpailijat analysoitiin tehdyn markkinaselvityksen avulla. Kerätyn tutkimusmateriaalin perusteella laadittiin kohdeyrityksen juustolaiteliiketoiminnalle kansainvälistymisstrategian linjaukset. Johtopäätöksenä todetaan aikaisemmin tehtyjen tunnettujen kansainvälistymisteorioiden yhdistelemisen käyttökelpoisuus tapauskohtaisesti sovellettuna useimpien teollisuudenalan pk-yritysten kansainvälistymissuunnitelmien laadinnassa. Jatkotutkimuksia ehdotetaan tehtäväksi globalisaation ja digitalisoitumisen avatessa uusia kansainvälistymismahdollisuuksia.

Rakennushankkeen suunnitteluvaiheen ratkaisut määrittävät merkittävästi hankkeen laatua, aikataulutusta ja kustannustasoa. Tutkimuksen tavoitteena oli selvittää teknisten suunnittelualustojen ja vakioinnin käytön nykytilaa sekä kustannusvaikutuksia kohdeyrityksessä. Kirjallisuustutkimuksessa suunnittelualustat nähtiin työkaluna vakioinnin lisäämiseen suunnitteluprosessissa ja hyvänä keinona suunnittelijoiden ohjaamiseksi. Työ on tutkimusmenetelmiltään laadullinen tapaustutkimus, jossa teknisten ratkaisuiden vakiointipotentiaalia ja kustannustehokkuutta tutkittiin kolmessa erityyppisessä rakenneratkaisussa. Kohdeyrityksen kustannustiedon ja asiantuntijahaastattelujen avulla vertaillut rakenteet oli ilmastointikonehuone, kylpyhuone ja parveke-elementti. Tutkimuksen keskeisissä tuloksissa suunnittelualustan ratkaisuiden käyttö kohdeyrityksessä on varsin säännönmukaista ja valvottua alustan käytön integroituessa osaksi suunnitteluprosessia. Vakioinnin ja esivalmistusasteen lisääminen tarjoaa potentiaalia parantaa rakennettavuutta ja laatua. Vakioinnin mahdollistama sarjavalmistuksen tehokkaampi hyödyntäminen ja vakioinnin volyymiedut ovat potentiaalinen keino alentaa yksikkökustannuksia. Vakioinnin ja esivalmistuksen aikatauluetujen kustannusvaikutus on merkittävä tuotannon aikasidonnaisten kustannusten pienentyessä ja pääoman käytön tehostuessa.

Kiinteistöosasto on yksi liiketoimintaa tukeva toiminto ja osaston strategia on johdettu pääosin konsernin strategiasta. Kiinteistöjen osuus Pirkanmaan Osuuskaupan tasearvosta on kuitenkin niin merkittävä, että kiinteistöstrategiassa on myös omia erityispiirteitä kuten kiinteistöjen salkutus. Strategiassa keskitytään tukemaan osuuskaupan omaa liiketoimintaa ja kaikki toimet tähtäävät loppuasiakkaan parempaan tyytyväisyyteen. Toimeenpanosuunnitelmassa on suuri rooli yhdessä tekemisellä ja kirjoittaja uskoo vahvasti sitoutumisen muutokseen muodostuvan asioiden keskustelemisen ja muutoksen merkityksen ymmärtämisen kautta. Tutkielman teoriaosuudessa käydään läpi kiinteistöstrategian teorioita, päästrategian ja tukitoimintostrategian suhdetta ja teorioita strategian toimeenpanosta. Prosessi eteni koko kiinteistöosaston henkilökunnan muutamasta yhteisestä päivästä ja päättyi kiinteistöstrategian toimeenpanosuunnitelmaan. Kaksi suurinta tekijää strategian toimeenpanon onnistumisessa ovat viestintä ja johtaminen. Yhteisten keskustelujen ansiosta saamme paremman lopputuloksen ja koko kiinteistöosaston henkilöstö on sitoutunut uuteen kiinteistöstrategiaan.

The Arctic region is experiencing a significant change in terms of climate change and a growing economic interest towards its natural resources and emerging business opportunities. The purpose of this study is to explore how can Finnish companies create sustainable business in the Arctic. This is done by examining the arctic business environment, identifying sectors with growth potential, addressing challenges related to operating in the Arctic and suggesting how to ensure sustainability and succeed in the globally competed arctic market. The theoretical framework is based on theories of sustainable development, corporate social responsibility and the role of strategy in creating sustainable business. Empirical data was collected by using qualitative research methods: first, background knowledge was formed based on written documents and, secondly, six expert interviews were conducted in early 2014. The interviewees represented the viewpoints of companies, political decision makers and NGO’s. The analysis of the data was conducted using thematic categorization. The empirical findings of the study suggest that in order to create sustainable business in the Arctic companies should adopt a long-term perspective, embrace a holistic approach to sustainability, understand interdependencies between the dimensions of sustainability and aim at high-level engagement in responsible behavior. To succeed in the arctic market core competencies, customer needs, multivendor cooperation and long-term presence need to be invested in on a company level. In addition, to promote and advance arctic development on a national level support is needed in terms of investments in infrastructure, funding research and design, creating a regulative framework and removing barriers of trade.

In this study, 7 men and women with an average age of 77 were interviewed regarding their experience of attending courses at a Learning in Retirement Institute (LRI) in southern Ontario. The purpose was to explore the role of wisdom in the learning of these retirees. Explicit theories of wisdom developed by selected philosophers, psychologists, and religious thinkers were compared to the implicit theories of wisdom that respondents expressed. Further comparisons were drawn between these implicit theories of wisdom and the act of perspective transformation in transformative learning. Some evidence was found that the development of wisdom compares favourably to perspective transformation, especially with regards to the behavioural changes associated with critical self-reflection. Among all the respondents, those 3 LRI stude.its who had also moderated courses indicated that they had experienced the most opportunities for critical self-reflection. These 3 also expressed deep satisfaction in having been able to put their learnings to use as teachers. A recommendation of this study is that opportunities for sharing and acting upon the results of discourse within Learning in Retirement Institutes should be implemented. In the absence of evaluation, opportunities for praxis (such as coop placements) must be developed so that students can measure their success against objective criteria and hence attach meaning to their studies.

Basic relationships between certain regions of space are formulated in natural language in everyday situations. For example, a customer specifies the outline of his future home to the architect by indicating which rooms should be close to each other. Qualitative spatial reasoning as an area of artificial intelligence tries to develop a theory of space based on similar notions. In formal ontology and in ontological computer science, mereotopology is a first-order theory, embodying mereological and topological concepts, of the relations among wholes, parts, parts of parts, and the boundaries between parts. We shall introduce abstract relation algebras and present their structural properties as well as their connection to algebras of binary relations. This will be followed by details of the expressiveness of algebras of relations for region based models. Mereotopology has been the main basis for most region based theories of space. Since its earliest inception many theories have been proposed for mereotopology in artificial intelligence among which Region Connection Calculus is most prominent. The expressiveness of the region connection calculus in relational logic is far greater than its original eight base relations might suggest. In the thesis we formulate ways to automatically generate representable relation algebras using spatial data based on region connection calculus. The generation of new algebras is a two pronged approach involving splitting of existing relations to form new algebras and refinement of such newly generated algebras. We present an implementation of a system for automating aforementioned steps and provide an effective and convenient interface to define new spatial relations and generate representable relational algebras.

In this work, we consider the properties of planar topological defects in unconventional superconductors. Specifically, we calculate microscopically the interaction energy of domain walls separating degenerate ground states in a chiral p-wave fermionic superfluid. The interaction is mediated by the quasiparticles experiencing Andreev scattering at the domain walls. As a by-product, we derive a useful general expression for the free energy of an arbitrary nonuniform texture of the order parameter in terms of the quasiparticle scattering matrix. The thesis is structured as follows. We begin with a historical review of the theories of superconductivity (Sec. 1.1), which led the way to the celebrated Bardeen-Cooper- Schrieffer (BCS) theory (Sec. 1.3). Then we proceed to the treatment of superconductors with so-called "unconventional pairing" in Sec. 1.4, and in Sec. 1.5 we introduce the specific case of chiral p-wave superconductivity. After introducing in Sec. 2 the domain wall (DW) model that will be considered throughout the work, we derive the Bogoliubov-de Gennes (BdG) equations in Sec. 3.1, which determine the quasiparticle excitation spectrum for a nonuniform superconductor. In this work, we use the semiclassical (Andreev) approximation, and solve the Andreev equations (which are a particular case of the BdG equations) in Sec. 4 to determine the quasiparticle spectrum for both the single- and two-DW textures. The Andreev equations are derived in Sec. 3.2, and the formal properties of the Andreev scattering coefficients are discussed in the following subsection. In Sec. 5, we use the transfer matrix method to relate the interaction energy of the DWs to the scattering matrix of the Bogoliubov quasiparticles. This facilitates the derivation of an analytical expression for the interaction energy between the two DWs in Sec. 5.3. Finally, to illustrate the general applicability our method, we apply it in Sec. 6 to the interaction between phase solitons in a two-band s-wave superconductor.

Qualitative spatial reasoning (QSR) is an important field of AI that deals with qualitative aspects of spatial entities. Regions and their relationships are described in qualitative terms instead of numerical values. This approach models human based reasoning about such entities closer than other approaches. Any relationships between regions that we encounter in our daily life situations are normally formulated in natural language. For example, one can outline one's room plan to an expert by indicating which rooms should be connected to each other. Mereotopology as an area of QSR combines mereology, topology and algebraic methods. As mereotopology plays an important role in region based theories of space, our focus is on one of the most widely referenced formalisms for QSR, the region connection calculus (RCC). RCC is a first order theory based on a primitive connectedness relation, which is a binary symmetric relation satisfying some additional properties. By using this relation we can define a set of basic binary relations which have the property of being jointly exhaustive and pairwise disjoint (JEPD), which means that between any two spatial entities exactly one of the basic relations hold. Basic reasoning can now be done by using the composition operation on relations whose results are stored in a composition table. Relation algebras (RAs) have become a main entity for spatial reasoning in the area of QSR. These algebras are based on equational reasoning which can be used to derive further relations between regions in a certain situation. Any of those algebras describe the relation between regions up to a certain degree of detail. In this thesis we will use the method of splitting atoms in a RA in order to reproduce known algebras such as RCC15 and RCC25 systematically and to generate new algebras, and hence a more detailed description of regions, beyond RCC25.

We propose two axiomatic theories of cost sharing with the common premise that agents demand comparable -though perhaps different- commodities and are responsible for their own demand. Under partial responsibility the agents are not responsible for the asymmetries of the cost function: two agents consuming the same amount of output always pay the same price; this holds true under full responsibility only if the cost function is symmetric in all individual demands. If the cost function is additively separable, each agent pays her stand alone cost under full responsibility; this holds true under partial responsibility only if, in addition, the cost function is symmetric. By generalizing Moulin and Shenker’s (1999) Distributivity axiom to cost-sharing methods for heterogeneous goods, we identify in each of our two theories a different serial method. The subsidy-free serial method (Moulin, 1995) is essentially the only distributive method meeting Ranking and Dummy. The cross-subsidizing serial method (Sprumont, 1998) is the only distributive method satisfying Separability and Strong Ranking. Finally, we propose an alternative characterization of the latter method based on a strengthening of Distributivity.

Il existe somme toute peu de théories du projet offrant une modélisation construite à partir de la complexité et de la diversité du projet d’architecture. Pourtant,certaines situations rassemblant parfois plusieurs dizaines de projets s’offrent d’elles-mêmes comme des situations comparatives et expérimentales : les concours d’architecture, d’urbanisme et de paysage. Le Laboratoire d’étude de l’architecture potentielle de l’Université de Montréal (Aménagement), après avoir développé un système d’archivage numérique des concours canadiens, a entrepris, avec le soutien du Groupement d’intérêt public « Europe des projets architecturaux et urbains », de développer la base de données documentaire des concours d’idées Europan. Au-delà des questions d’archivage numérique, se profilent clairement des possibilités de théorisation s’appuyant sur les logiques d’une base de données, en particulier sur la constitution du diagramme entités et relations, modélisation indispensable à sa traduction informatique. Cette recherche entreprend une première mise à jour de ces éléments conceptuels et tend à montrer que la base de données est un véritable modèle théorique du projet ouvrant sur de nouvelles avenues de recherche et de connaissance.

Dans une époque de changements des moyens de représentation et communication en architecture, cette recherche porte sur l’enseignement de la conception architecturale et plus spécifiquement sur l’apport que l’informatique pourrait avoir dans ce processus. En nous basant sur une méthodologie qualitative, exploratoire et participative, nous y procédons par enchainement de questions, celle de départ étant la suivante: Comment l’enseignement de la conception architecturale pourrait tirer avantage des moyens numériques? Notre objectif est de proposer des méthodes et des outils d’apprentissage aux étudiants en architecture pour enrichir leurs démarches de conception grâce à l’ordinateur. Après une revue de la littérature dans le domaine, et un approfondissement de l’étude sur le rôle des référents architecturaux et sur la conception intégrée, nous avons procédé à une observation exploratoire du travail des étudiants en atelier d’architecture. Ces premières étapes de la recherche ont permis de dégager des discordances entre les positions théoriques et la pratique en l’atelier, pour concrétiser ultérieurement la question de recherche. Dans le but de discerner des méthodes efficaces et innovatrices pour répondre aux discordances identifiées, nous avons engagé une étude de la littérature sur les théories cognitives par rapport aux connaissances, l’apprentissage et la conception. Certaines stratégies ont pu être définies, notamment la nécessité de représentation multimodale des référents architecturaux, l’importance de représenter le processus et non seulement le résultat, ainsi que l’avantage d’inciter les étudiants à travailler dans leur ‘zone proximale’ de développement. Suite à ces recherches, une méthode d’enseignement complémentaire a été définie. Elle propose aux étudiants des explorations de l’objet en conception basées sur la manipulation des savoir-faire architecturaux. Cette méthode a été opérationnalisée d’un point de vue pédagogique ainsi que didactique et mise à l’épreuve auprès des étudiants en atelier. Un prototype de librairie de référents architecturaux interactifs (LibReArchI) a été créé dans ce but. Elle a été conçue en tant qu’environnement de conception et espace de partage de savoir-faire entre étudiants et enseignants. Les principaux résultats de cette recherche démontrent le rôle positif de la méthode proposée pour le transfert des savoir-faire architecturaux lors de l’apprentissage en atelier. Son potentiel d’assister la conception intégrée et de stimuler l’émergence d’idées a été constaté. Au niveau théorique, un modèle d’un cycle du processus de design avec le numérique a été esquissé. En conclusion, des avenues de développements futurs de cette recherche sont proposées.
