Venäläisten suuryritysten innovatiivisuus

Tämän kandidaatin työn tavoitteena on selvittää kuinka innovatiivisia venäläiset suuryritykset ovat kansainvälisellä tasolla mitattuna, ja miten se vaikuttaa niiden tulevaisuuden kilpailukykyyn globaaleilla markkinoilla. Lisäksi työssä tutkitaan yritysten organisaatiokulttuuria innovaatiostrategian ja sen johtamisen näkökulmasta, häiritsevien innovaatioiden aiheuttamia paineita uusien tulonansaintamallien luontiin sekä etuja ja haittoja, joita Venäjä antaa yritysten kansainvälistymiseen. Työssä tutkitaan kahdeksaa suurinta venäläistä yhtiötä, joiden tilinpäätöstiedoista on saatavilla tuotekehityskulut ja liikevaihto. Näitä lukuja verrataan kansainvälisellä tasolla muiden maiden yrityksiin ja analysoidaan sen pohjalta Venäjän tulevaisuuden näkymiä globaalissa kilpailussa. Venäläisten suuryritysten on kovan kansainvälisen kilpailun vuoksi laajennettava ansaintamahdollisuuksiaan. Pelkästään öljyn ja maakaasun tuottamaan hyvinvointiin ei voi ikuisesti tukeutua, sillä jo nyt on olemassa kilpailukykyisempiä vaihtoehtoja ja ratkaisuja. Suuryritysten tuotekehitysmenojen suhteellinen osuus liikevaihdosta on pienempi kuin Venäjän valtion ja kilpailijoiden keskiarvo. Lisäksi innovaatiokulttuurin puute, koulutuksen laadun heikentyminen sekä maassa vallitseva byrokratia estävät innovaatioiden tehokkaan kehittämisen ja hyödyntämisen.

Teollinen symbioosi - kansallisen ohjelman toteuttaminen Suomessa Britanniaan verrattuna

This master thesis examines the possibility of implementing a national industrial symbiosis programme in Finland. Industrial symbiosis is a close cooperation between companies in which the actors make use of each other's wastes and by-products as raw materials for pro-cesses. Symbiosis programme aims to promote industrial symbiosis by identifying possible synergies. In the United Kingdom (UK), a national level programme NISP (National Industri-al Symbiosis Programme) has been successfully implemented. This thesis studies whether it would be possible to implement a similar program in Finland. The implementation of the pro-gram in Finland is evaluated by analyzing and comparing Finnish and British business envi-ronments using PESTEL and diamond models. The goal is to identify factors that promote or hinder the implementation of the programme in Finland. Based on this study, it can be said that implementing the programme in Finland is possible. The programme can be carried out in almost the same principles as in the UK, but some char-acteristics of the Finnish business environment, such as the high level of technological know-how, should especially be taken as an advantage. On the other hand, there are features, such as low level domestic demand, which may prevent the implementation of the program unless they are given special attention.

The regional and global competitiveness of multinational firms

International competitiveness ultimately depends upon the linkages between a firm’s unique, idiosyncratic capabilities (firm-specific advantages, FSAs) and its home country assets (country-specific advantages, CSAs). In this paper, we present a modified FSA/CSA matrix building upon the FSA/CSA matrix (Rugman 1981). We relate this to the diamond framework for national competitiveness (Porter 1990), and the double diamond model (Rugman and D’Cruz 1993). We provide empirical evidence to demonstrate the merits and usefulness of the modified FSA/CSA matrix using the Fortune Global 500 firms. We examine the FSAs based on the geographic scope of sales and CSAs that can lead to national, home region, and global competitiveness. Our empirical analysis suggests that the world’s largest 500 firms have increased their firm-level international competitiveness. However, much of this is still being achieved within their home region. In other words, international competitiveness is a regional not a global phenomenon. Our findings have significant implications for research and practice. Future research in international marketing should take into account the multi-faceted nature of FSAs and CSAs across different levels. For MNE managers, our study provides useful insights for strategic marketing planning and implementation.

Construção de vínculos de confiança empresarial

O trabalho apresentado neste relatório tem por objetivo pesquisar a constituição e o desenvolvimento da confiança entre os empresários participantes do programa Cooperar para Competir, o qual compõe o conjunto de treinamentos oferecidos para o Arranjo Produtivo Local de Birigui pelo SEBRAE-SP em parceria com instituições locais como o Sindicato da Indústrias do Calçado e Vestuário de Birigui, o SESI de Birigui, entre outros. Em termos de metodologia, foi escolhido o método qualitativo para desenvolver uma pesquisa exploratória de estudo de caso (o Cooperar para Competir) e foram utilizadas duas técnicas de pesquisa – a entrevista aberta ou não-dirigida e a técnica de história oral. Para o seu desenvolvimento, foram estabelecidas três grandes áreas de investigação que, juntas, ofereceriam uma visão abrangente do tema analisado: a) a primeira grande área é responsável pelo estudo do contexto e da estrutura econômica do APL em geral, bem como de seus agentes presentes naquela região e suas particularidades. Nesta primeira parte são apresentadas discussões sobre clusters, sua importância e representatividade no Brasil e no mundo, bem como uma análise do cluster calçadista de Birigui de acordo com o Modelo Diamante proposto por Porter (1999); b) a segunda área abrange tanto a estrutura formal do Cooperar para Competir em cada uma das turmas quanto o processo dinâmico do curso, seus momentos críticos e as estratégias pedagógicas adotadas a cada momento em vista dos desafios. Esta parte contextualiza o programa, apresenta sua estrutura e reflete a construção das bases de cooperação em sala de aula por uma perspectiva axiológica; c) a terceira área, por fim, é caracterizada pela pesquisa de campo, quando foram investigadas as vivências, experiências e impactos dos e nos participantes do ponto de vista subjetivo e como eles entenderam os efeitos em suas vidas profissional e pessoal. As entrevistas abertas foram realizadas com dois grupos de participantes, o Grupo Graduado e o Grupo Novo, a fim entender o desenvolvimento de ambos os grupos, os resultados alcançados pelo primeiro e o efeito da suspensão do programa no segundo. Todo o processo seguido durante a pesquisa permitiu que se chegasse a inúmeras conclusões, como o porquê do sucesso do programa Cooperar para Competir – o sucesso, neste caso, reside no desenho pedagógico que atende a dimensão axiológica, ou seja, não apenas se falou de cooperação, mas se produziu cooperação ao integrar competências, interesses e valores. O programa serviu, então, como um espaço filosófico e laboratorial. Assim, o conteúdo e a sequência seguidos também tem sua importância relativizada frente as relações e a construção de algo que transcende o caráter utilitarista ou funcionalista das disciplinas. As entrevistas individuais e em grupo mostraram que se reconhecerem como iguais foi um fator gerador de confiança entre os participantes, a qual também é expressa quando estes se abrem para compreenderem o modo como os outros atribuem significados para a relação de desconfiança e confiança e passam a estabelecer um sistema de significação comum. Além disso, a consciência de sua realidade e o reconhecimento de sua responsabilidade junto a si mesmo, à sua empresa, ao projeto desenvolvido no Cooperar para Competir e à comunidade de Birigui marcam, também, a mudança do esquema mental de sapateiro para empresário.

A note on convergence of Peck-Shell and Green-Lin mechanisms in the Diamond-Dybvig model

We study the effects of population size in the Peck-Shell analysis of bank runs. We find that a contract featuring equal-treatment for almost all depositors of the same type approximates the optimum. Because the approximation also satisfies Green-Lin incentive constraints, when the planner discloses positions in the queue, welfare in these alternative specifications are sandwiched. Disclosure, however, it is not needed since our approximating contract is not subject to runs.

Thermal diffusion in molecular dynamics simulations of thin film diamond deposition

Molecular dynamics simulations of carbon atom depositions are used to investigate energy diffusion from the impact zone. A modified Stillinger-Weber potential models the carbon interactions for both sp2 and sp3 bonding. Simulations were performed on 50 eV carbon atom depositions onto the (111) surface of a 3.8 x 3.4 x 1.0 nm diamond slab containing 2816 atoms in 11 layers of 256 atoms each. The bottom layer was thermostated to 300 K. At every 100th simulation time step (27 fs), the average local kinetic energy, and hence local temperature, is calculated. To do this the substrate is divided into a set of 15 concentric hemispherical zones, each of thickness one atomic diameter (0.14 nm) and centered on the impact point. A 50-eV incident atom heats the local impact zone above 10 000 K. After the initial large transient (200 fs) the impact zone has cooled below 3000 K, then near 1000 K by 1 ps. Thereafter the temperature profile decays approximately as described by diffusion theory, perturbed by atomic scale fluctuations. A continuum model of classical energy transfer is provided by the traditional thermal diffusion equation. The results show that continuum diffusion theory describes well energy diffusion in low energy atomic deposition processes, at distance and time scales larger than 1.5 nm and 1-2 ps, beyond which the energy decays essentially exponentially.

Electrochemical oxidation of acid black 210 dye on the boron-doped diamond electrode in the presence of phosphate ions: Effect of current density, pH, and chloride ions

The electrochemical oxidation of acid black 210 dye (AB-210) on the boron-doped diamond (BDD) was investigated under different pH conditions. The best performance for the AB-210 oxidation occurred in alkaline phosphate solution. This is probably due to oxidizing agents such as phosphate radicals and peroxodiphosphate ions, which can be electrochemically produced with good yields on the BDD anode, mainly in alkaline solution. Under this condition, the COD (chemical oxygen demand) removal was higher than that obtained from the model proposed by Comninellis. Electrolyses performed in phosphate buffer and in the presence of chloride ions resulted in faster COD and color removals in acid and neutral solutions, but in alkaline phosphate solution, a better performance in terms of TOC removal was obtained in the absence of chloride. Moreover, organochloride compounds were detected in all electrolyses performed in the presence of chloride. The AB-210 electrooxidation on BDD using phosphate as supporting electrolyte proved to be interesting since oxidizing species generated from phosphate ions were able to completely degrade the dye without producing organochloride compounds.

Development of a short-term model using petrophysical logging at Century Mine, North Queensland

Pasminco Century Mine has developed a geophysical logging system to provide new data for ore mining/grade control and the generation of Short Term Models for mine planning. Previous work indicated the applicability of petrophysical logging for lithology prediction, however, the automation of the method was not considered reliable enough for the development of a mining model. A test survey was undertaken using two diamond drilled control holes and eight percussion holes. All holes were logged with natural gamma, magnetic susceptibility and density. Calibration of the LogTrans auto-interpretation software using only natural gamma and magnetic susceptibility indicated that both lithology and stratigraphy could be predicted. Development of a capability to enforce stratigraphic order within LogTrans increased the reliability and accuracy of interpretations. After the completion of a feasibility program, Century Mine has invested in a dedicated logging vehicle to log blast holes as well as for use in in-fill drilling programs. Future refinement of the system may lead to the development of GPS controlled excavators for mining ore.

A uniform white-noise model for fixed-point roundoff errors in digital systems

Fixed-point roundoff noise in digital implementation of linear systems arises due to overflow, quantization of coefficients and input signals, and arithmetical errors. In uniform white-noise models, the last two types of roundoff errors are regarded as uniformly distributed independent random vectors on cubes of suitable size. For input signal quantization errors, the heuristic model is justified by a quantization theorem, which cannot be directly applied to arithmetical errors due to the complicated input-dependence of errors. The complete uniform white-noise model is shown to be valid in the sense of weak convergence of probabilistic measures as the lattice step tends to zero if the matrices of realization of the system in the state space satisfy certain nonresonance conditions and the finite-dimensional distributions of the input signal are absolutely continuous.

Nonempirical cluster-model study of the chemisorption of atomic hydrogen on the (111) surface of diamondlike crystals

The interaction of atomic hydrogen with C4H9, Si4H9, and Ge4H9 model clusters has been studied using all-electron and pseudopotential ab initio Hartree-Fock computations with basis sets of increasing flexibility. The results show that the effect of polarization functions is important in order to reproduce the experimental findings, but their inclusion only for the atoms directly involved in the chemisorption bond is usually sufficient. For the systems H-C4H9 and H-Si4H9 all-electron and pseudopotential results are in excellent agreement when basis sets of comparable quality are used. Besides, semiempirical modified-neglect-of-differential-overlap computations provide quite reliable results both for diamond and silicon and have been used to investigate larger model clusters. The results confirm the local nature of chemisorption and further justify the use of minimal X4H9 model clusters.

Influence of chloride-mediated oxidation on the electrochemical degradation of the direct black 22 dye using boron-doped diamond and β-PbO2 anodes

The Direct Black 22 dye was electrooxidized at 30 mA cm-2 in a flow cell using a BDD or β-PbO2 anode, varying pH (3, 7, 11), temperature (10, 25, 45 °C), and [NaCl] (0 or 1.5 g L-1). In the presence of NaCl, decolorization rates were similar for all conditions investigated, but much higher than predicted through a theoretical model assuming mass-transport control; similar behavior was observed for COD removal (at pH 7, 25 °C), independently of the anode. With no NaCl, COD removals were also higher than predicted with a theoretical model, which suggests the existence of distinct dye degradation pathways.

Synthesis, structural analysis, and magnetic behaviour of three fumarate bridged coordination polymers: five-fold interpenetrated diamond-like net of Ni-II, sheets of Ni-II and Co-II

The hydrothermal reactions of Ni(NO3)(2).6H(2)O, disodium fumarate (fum) and 1,2-bis(4-pyridyl)ethane (bpe)/1,3-bis(4-pyridyl) propane (bpp) in aqueous-methanol medium yield one 3-D and one 2-D metal-organic hybrid material, [Ni(fum)(bpe)] (1) and [Ni(fum)(bpp)(H2O)] (2), respectively. Complex 1 possesses a novel unprecedented structure, the first example of an "unusual mode" of a five-fold distorted interpenetrated network with metal-ligand linkages where the four six-membered windows in each adamantane-type cage are different. The structural characterization of complex 2 evidences a buckled sheet where nickel ions are in a distorted octahedral geometry, with two carboxylic groups, one acting as a bis-chelate, the other as a bis-monodentate ligand. The metal ion completes the coordination sphere through one water molecule and two bpp nitrogens in cis position. Variable-temperature magnetic measurements of complexes 1 and 2 reveal the existence of very weak antiferromagnetic intramolecular interactions and/or the presence of single-ion zero field splitting (D) of isolated Ni-II ions in both the compounds. Experimentally, both the J parameters are close, comparable and very small. Considering zero-field splitting of Ni-II, the calculated D values are in agreement with values reported in the literature for Ni-II ions. Complex 3, [{Co(phen)}(2)(fum)(2)] (phen=1,10-phenanthroline) is obtained by diffusing methanolic solution of 1,10-phenanthroline on an aqueous layer of disodium fumarate and Co(NO3)(2).6H(2)O. It consists of dimeric Co-II(phen) units, doubly bridged by carboxylate groups in a distorted syn-syn fashion. These fumarate anions act as bis-chelates to form corrugated sheets. The 2D layer has a (4,4) topology, with the nodes represented by the centres of the dimers. The magnetic data were fitted ignoring the very weak coupling through the fumarate pathway and using a dimer model.

Modelling the rheology of sea ice as a collection of diamond-shaped floes

In polar oceans, seawater freezes to form a layer of sea ice of several metres thickness that can cover up to 8% of the Earth’s surface. The modelled sea ice cover state is described by thickness and orientational distribution of interlocking, anisotropic diamond-shaped ice floes delineated by slip lines, as supported by observation. The purpose of this study is to develop a set of equations describing the mean-field sea ice stresses that result from interactions between the ice floes and the evolution of the ice floe orientation, which are simple enough to be incorporated into a climate model. The sea ice stress caused by a deformation of the ice cover is determined by employing an existing kinematic model of ice floe motion, which enables us to calculate the forces acting on the ice floes due to crushing into and sliding past each other, and then by averaging over all possible floe orientations. We describe the orientational floe distribution with a structure tensor and propose an evolution equation for this tensor that accounts for rigid body rotation of the floes, their apparent re-orientation due to new slip line formation, and change of shape of the floes due to freezing and melting. The form of the evolution equation proposed is motivated by laboratory observations of sea ice failure under controlled conditions. Finally, we present simulations of the evolution of sea ice stress and floe orientation for several imposed flow types. Although evidence to test the simulations against is lacking, the simulations seem physically reasonable.

Non-orthogonal version of the arbitrary polygonal C-grid and a new diamond grid

Quasi-uniform grids of the sphere have become popular recently since they avoid parallel scaling bottle- necks associated with the poles of latitude–longitude grids. However quasi-uniform grids of the sphere are often non- orthogonal. A version of the C-grid for arbitrary non- orthogonal grids is presented which gives some of the mimetic properties of the orthogonal C-grid. Exact energy conservation is sacrificed for improved accuracy and the re- sulting scheme numerically conserves energy and potential enstrophy well. The non-orthogonal nature means that the scheme can be used on a cubed sphere. The advantage of the cubed sphere is that it does not admit the computa- tional modes of the hexagonal or triangular C-grids. On var- ious shallow-water test cases, the non-orthogonal scheme on a cubed sphere has accuracy less than or equal to the orthog- onal scheme on an orthogonal hexagonal icosahedron. A new diamond grid is presented consisting of quasi- uniform quadrilaterals which is more nearly orthogonal than the equal-angle cubed sphere but with otherwise similar properties. It performs better than the cubed sphere in ev- ery way and should be used instead in codes which allow a flexible grid structure.
