The transforming network of a foreign company operating in Mongolia. Case: A Finnish firm in Mongolia

In the globalising business environment ever fewer market areas remain unknown. Mongolia is yet only considered as an isolated strip between two power states. The purpose of this study is to put Mongolia on the map of academic business research. This is done by describing the transforming network of a foreign company operating in Mongolia. The objective of the study is approached through a case study, which presents the transformation of a Finnish company operating in Mongolia. This study aims at providing understanding on how the foreign case company observes the transformations of its network. The transformation within the case company is reflected to the transformations that occur in the Mongolian business environment. This study was conducted through a qualitative, intrinsic case study approach. The empirical data was gathered by using the method of network pictures. The network pictures were completed with the assistance of themed interviews. In order to be able to analyse the transformation within a network, three different time periods were observed: the past period around 2000, the present around 2014, and the estimated future around 2020. The data was collected from four executives positioned either in Finland, Russia or Mongolia. The respondents have a long experience within the case company, they hold managerial position, and therefore were able to offer valuable data for this study. The analytical framework used to analyse the collected data was built on the industrial network model, the ARA (actors-resources-activities)-model. The study shows that the changing business environment of Mongolia was utilised by the case company. In order to better meet the transforming customer wishes, the case company transformed from being a retailer to being a manufacturer. The case company was able to become a pioneer in the market. Thus, the case company has undergone similar kind of rapid transformation as the economy of Mongolia in entirety. This study shows that the general nature of the ARA-model makes it usable for new research contexts. The initial ARA-model offers a way to identify the dimensions of a network and a mean to understand these dimensions. The ARA-model can be applied to different contexts and to all time dimensions, past, present and future. The managerial recommendations offered in this study are directed towards the managers that plan to start operations in Mongolia. While this study is the first of its kind, it offers a good starting point for the future research on the change of Mongolian business networks. Valuable information could, for example, be obtained from a comparative study between the case company of this study and a multinational mining company operating in Mongolia.

Pollen and grain size records in abyssal sediments of the northwest Pacific Ocean as proxies of Plio-Pleistocene climate change /

A distinctive period of global change occurred during the PUocene between the warm Miocene and subsequent Quaternary cooling. Samples from Ocean Drilling Project Site 11 79 (-5586 mbsl, 41°4'N, 159°57'E), Site 881 (-5765 mbsl, 47°6.133'N, 161°29.490'E) and Site 882 (-3255 mbsl, 50°22'N, 167°36'E) were studied to determine the magnitude and composition ofterrigenous flux to the western mid-latitude North Pacific and its relation to climate change in East Asia since the mid-Pliocene. Dust-sized particles (including pollen), sourced from the arid regions and loess plateaus in East Asia are entrained by prevailing westerly winds and transported to the midlatitude northwest North Pacific Ocean. This is recorded by peaks in the total concentration of pollen and spores, as well as the mean grain size of allochthonous and autochthonous silicate material in abyssal marine sediments. Aridification of the Asian interior due to the phased uplift of the Himalayan-Tibetan Plateau created the modem East Asian Monsoon system dominated by a strengthening of the winter monsoon. The winter monsoon is further enhanced during glacials due to the expansion of desert and steppe environments at the expense ofwoodlands and forests recorded by the composition of palynological assemblages. The late Pliocene-Pleistocene glacials at ODP Sites 1 179, 881, and 882 are characterized by increases in grain size, magnetic susceptibility, pollen and spore concentrations around 3.5-3.3, 2.6-2.4, 1.7-1.6, and 0.9-0.7 Ma (ages based on magnetostratigraphic and biostratigraphic datums). The peaks during these times are relatively rich in pollen taxa derived primarily from steppe and boreal vegetation zones, recording cool, dry climates. The overall size increase of sediment and abundance of terrestrial palynomorphs record enhanced wind strength. The increase in magnitude of pollen and spore concentrations as well as grain size record global cooling and Northern Hemisphere glaciation. The peaks in grain size as well as pollen and spore abundance in marine sediments correlate with the mean grain size of loess in East Asia, consistent with the deflation of unarmoured surfaces during glacials. The transport of limiting nutrients to marine environments enhanced sea surface productivity and increased the rate of sediment accumulation.

Phonon dispersion curves and atomic mean square displacement for several fcc and bcc materials

The atomic mean square displacement (MSD) and the phonon dispersion curves (PDC's) of a number of face-centred cubic (fcc) and body-centred cubic (bcc) materials have been calclllated from the quasiharmonic (QH) theory, the lowest order (A2 ) perturbation theory (PT) and a recently proposed Green's function (GF) method by Shukla and Hiibschle. The latter method includes certain anharmonic effects to all orders of anharmonicity. In order to determine the effect of the range of the interatomic interaction upon the anharmonic contributions to the MSD we have carried out our calculations for a Lennard-Jones (L-J) solid in the nearest-neighbour (NN) and next-nearest neighbour (NNN) approximations. These results can be presented in dimensionless units but if the NN and NNN results are to be compared with each other they must be converted to that of a real solid. When this is done for Xe, the QH MSD for the NN and NNN approximations are found to differ from each other by about 2%. For the A2 and GF results this difference amounts to 8% and 7% respectively. For the NN case we have also compared our PT results, which have been calculated exactly, with PT results calculated using a frequency-shift approximation. We conclude that this frequency-shift approximation is a poor approximation. We have calculated the MSD of five alkali metals, five bcc transition metals and seven fcc transition metals. The model potentials we have used include the Morse, modified Morse, and Rydberg potentials. In general the results obtained from the Green's function method are in the best agreement with experiment. However, this improvement is mostly qualitative and the values of MSD calculated from the Green's function method are not in much better agreement with the experimental data than those calculated from the QH theory. We have calculated the phonon dispersion curves (PDC's) of Na and Cu, using the 4 parameter modified Morse potential. In the case of Na, our results for the PDC's are in poor agreement with experiment. In the case of eu, the agreement between the tlleory and experiment is much better and in addition the results for the PDC's calclliated from the GF method are in better agreement with experiment that those obtained from the QH theory.

The sedimentology of unconsolidated deltaic and aeolian sediments east of Dunnville, Ontario /

Surficial sediments east of Dunnville, Ontario representing a limited deltaic/lacustrine/aeolian system are investigated with the aim of defining and interpreting their geological history by means of exarrrrning their sedimentology and interrelationships. The Folk and \oJard grain size statistics of samples fran the area were calculated. These sample parameters were e1en plotted on maps to detennine regional patterns. The strongest pattern observed was one of distinct fining to the east, away fran the sand source. Aeolian deposits were fourrl to be better sorted than the surrcunding sediments. The grain size parameter values were also plotted on bivariate graphs in an attempt to separate the samples according to depositional environment. This exercise met with little success, as rrost of the sediments sampled in the area have similar grain size parameters. This is believed to be because the sediment sources for the different environments (delta, distal delta, aeolian dune) are intimately related, to the point that nnst dunes appear to have been sourcErl fran immediately local sediments. It is FOstulated that in such a srrall sedimentological sub-system, sediments were not involved in active transport for a length of time sufficient for the rraterial to cane to equilibritnn with its transporting medium. Thus, fe..v distinctive patterns of parameters were developed that would enable one to differentiate between various environments of neposition. The i.rnTaturity of rrany dune forms and the i.Imaturity of mineralogical composition of all deposits support the above hyt:XJthesis of limited transport time. Another hypothesis proposen is that eadh geologically or geographically distinct area or "sub-system" rray have its o,.m "signature" of grain size relationships as plotted on bivariate graphs. Thus, the emphasis, concerning graphs of this type, should not be placErl on attempting to nifferentiate between various environnents of deposition, hut raB1er on investigating the interrelationships between sanples am environments within that "sub-system". Through the course of this investigation, the existence of nelta plain distributary Channels in the thesis area is SUG0ested, and the mscovery of significantly mfferent sub-units within the TUnnville dune sediments is documented. It is inferred by reference to other authors interpretations of the glacial history of the area, that the tirre of effective aeolian acti vi ty in the Dunnville area was between 12,300 to 12,100 years R.p.

Desert and Distributive Efficiency

It is highly desirable for an allocation of goods to be efficient. However, one might also deem it important that an allocation gives individuals what they deserve. This paper investigates whether it is possible for an allocation to be both efficient and give people what they deserve. It will first of all consider comparative desert, and conclude that it is possible to satisfy both desiderata. It will then consider absolute desert by integrating Shelly Kagan’s work on desert and economic theory. The conclusion will be that there are potential conflicts between absolute desert and efficiency. The paper will then examine how to select the best compromise between the two values, considering several different conceptions of absolute desert.

Les impacts de la dispersion historique sur la variabilité génétique à différentes échelles spatiales : connaître l'histoire pour mieux comprendre le présent.

La variabilité génétique actuelle est influencée par une combinaison complexe de variables historiques et contemporaines. Dès lors, une interprétation juste de l’impact des processus actuels nécessite une compréhension profonde des processus historiques ayant influencé la variabilité génétique. En se basant sur la prémisse que des populations proches devraient partager une histoire commune récente, nombreuses études, effectuées à petite échelle spatiale, ne prennent pas en considération l’effet potentiel des processus historiques. Cette thèse avait pour but de vérifier la validité de cette prémisse en estimant l’effet de la dispersion historique à grande et à petite échelle spatiale. Le premier volet de cette thèse avait pour but d’évaluer l’impact de la dispersion historique sur la répartition des organismes à grande échelle spatiale. Pour ce faire, les moules d’eau douce du genre flotteurs (Pyganodon spp.) ont servies de modèle biologique. Les moules d'eau douce se dispersent principalement au stade larvaire en tant que parasites des poissons. Une série de modèles nuls ont été développés pour évaluer la co-occurrence entre des parasites et leurs hôtes potenitels. Les associations distinctes du flotteur de Terre-Neuve (P. fragilis) avec des espèces de poissons euryhalins permettent d’expliquer sa répartition. Ces associations distinctes ont également pu favoriser la différenciation entre le flotteur de Terre-Neuve et son taxon soeur : le flotteur de l’Est (P. cataracta). Cette étude a démontré les effets des associations biologiques historiques sur les répartitions à grande échelle spatiale. Le second volet de cette thèse avait pour but d’évaluer l’impact de la dispersion historique sur la variabilité génétique, à petite échelle spatiale. Cette fois, différentes populations de crapet de roche (Ambloplites rupestris) et de crapet soleil (Lepomis gibbosus), dans des drainages adjacents ont servies de modèle biologique. Les différences frappantes observées entre les deux espèces suggèrent des patrons de colonisation opposés. La faible diversité génétique observée en amont des drainages et la forte différenciation observée entre les drainages pour les populations de crapet de roche suggèrent que cette espèce aurait colonisé les drainages à partir d'une source en aval. Au contraire, la faible différenciation et la forte diversité génétique observées en amont des drainages pour les populations de crapet soleil suggèrent une colonisation depuis l’amont, induisant du même coup un faux signal de flux génique entre les drainages. La présente étude a démontré que la dispersion historique peut entraver la capacité d'estimer la connectivité actuelle, à petite échelle spatiale, invalidant ainsi la prémisse testée dans cette thèse. Les impacts des processus historiques sur la variabilité génétique ne sont pas faciles à démontrer. Le troisième volet de cette thèse avait pour but de développer une méthode permettant de les détecter. La méthode proposée est très souple et favorise la comparaison entre la variabilité génétique et plusieurs hypothèses de dispersion. La méthode pourrait donc être utilisée pour comparer des hypothèses de dispersion basées sur le paysage historique et sur le paysage actuel et ainsi permettre l’évaluation des impacts historiques et contemporains sur la variabilité génétique. Les performances de la méthode sont présentées pour plusieurs scénarios de simulations, d’une complexité croissante. Malgré un impact de la différentiation globale, du nombre d’individus ou du nombre de loci échantillonné, la méthode apparaît hautement efficace. Afin d’illustrer le potentiel de la méthode, deux jeux de données empiriques très contrastés, publiés précédemment, ont été ré analysés. Cette thèse a démontré les impacts de la dispersion historique sur la variabilité génétique à différentes échelles spatiales. Les effets historiques potentiels doivent être pris en considération avant d’évaluer les impacts des processus écologiques sur la variabilité génétique. Bref, il faut intégrer l’évolution à l’écologie.

Étude de la variabilité spectroscopique d’un échantillon d’étoiles Wolf-Rayet de type WC9

Nous savons que la grande majorité des étoiles WC9 produit de la poussière à base de carbone. Cette dernière doit se former dans des zones de très haute densité afin de survivre à l’environnement hostile qu’est celui du vent d’une étoile WR. Les étoiles WC appartenant à un système binaire WR + O produisent de la poussière quand les vents des deux étoiles entrent en collision et forment une zone de choc pouvant augmenter la densité du gaz d’un facteur 1000. Par contre, plusieurs étoiles WC9 n’ont, à ce jour, montré aucun signe de la présence d’un compagnon. Le but du projet est de tenter d’identifier un mécanisme alternatif responsable de la formation de poussière dans les étoiles WC9 n’appartenant pas à un système binaire. Nous présentons les résultats d’une campagne d’observation visant à caractériser la variabilité spectroscopique d’un échantillon de huit étoiles WC9 et une étoile WC8d. Nos résultats indiquent que la majorité des étoiles montrent des variations à grande échelle dans la raie d’émission C III 5696, soit à un niveau d’au moins 5% du flux de la raie et que les structures dans le vent ont une dispersion de vitesses de l’ordre de 150-300 km/s. De manière générale, les variations de vitesse radiales sont anti-corrélées avec le coefficient d’asymétrie de la raie, ce qui semble infirmer la présence d’un compagnon. Des observations en photométrie de l’étoile WR103 montrent une période de 9.1 ± 0.6 jours qui s’accorde avec les variations spectroscopiques et qui ne semble pas, de manière évidente, d’origine binaire.

Dispersion de la couleur J-K des naines brunes de type L2

Les naines brunes sont des objets de masse intermédiaire entre celle nécessaire pour former une étoile et celle d'une planète. Les naines brunes sont classées, des plus chaudes aux plus froides, en types spectraux L, T et Y, caractérisés par une couleur J-K moyenne qui varie de 1.2 à 1.8 pour les étoiles de type L0 à L8, et de 1.8 à -0.5 pour les étoiles de type L8 à T8. Par ailleurs, la couleur J-K de certains types spectraux présente une dispersion de l'ordre d'une magnitude. Ce travail tente de faire la lumière sur la nature de cette grande dispersion, présente dans la couleur J-K des naines brunes de type L2. Les observations ont été réalisées avec la caméra infrarouge CPAPIR à l'Observatoire du Mont Mégantic. Nous avons ciblé un total de 22 naines brunes qui ont été observées en K, et 12 parmi celles-ci ont aussi été observées en J. Chacune des naines brunes a été calibrée à l'aide d'une étoile standard, ce qui rend nos résultats indépendants des données 2MASS. Nous observons une corrélation entre les couleurs J-K de nos données et de celles de 2MASS. Cela montre que la grande dispersion en J-K de nos données et des données 2MASS est due aux propriétés physiques des naines brunes et non à des erreurs observationnelles. L'examen des facteurs qui pourraient être responsables de cette grande dispersion, soit la classification spectrale, la métallicité, la gravité de surface, une binarité non résolue, la présence de nuages de condensats et la rotation, montre que la gravité de surface serait le facteur le plus susceptible d'être responsable de la grande dispersion des valeurs de J-K.

Synthesis, characterization and hydrodesulphurisation activity of CoMo/gama-Al2O3 catalyst prepared through molecular designed dispersion method

CoMo/gama-Al2O3 catalysts for hydrodesulphurisation activity were prepared by making use of the molecular designed dispersion (MDD) method. Molybdenum and cobalt pyrrolidine-N-carbodithioate (Pydtc) complexes were used for the incorporation of metals on the support. The catalysts were characterized by elemental analysis, low temperature oxygen chemisorption, temperature programmed reduction (TPR) and laser Raman spectroscopy. The hydrodesulphurisation activity of all the catalysts were carried out and results were compared with those of the catalysts prepared through the conventional method. Higher molybdenum dispersion, smaller molybdenum clusters, lower reduction temperature of catalyst and better hydrodesulphurisation activity were observed for the catalysts prepared through the MDD method

THE RED RAIN PHENOMENON OF KERALA AND ITS POSSIBLE EXTRATERRESTRIAL ORIGIN

A red rain phenomenon occurred in Kerala, India starting from 25th July 2001, in which the rainwater appeared coloured in various localized places that are spread over a few hundred kilometers in Kerala. Maximum cases were reported during the first 10 days and isolated cases were found to occur for about 2 months. The striking red colouration of the rainwater was found to be due to the suspension of microscopic red particles having the appearance of biological cells. These particles have no similarity with usual desert dust. An estimated minimum quantity of 50,000 kg of red particles has fallen from the sky through red rain. An analysis of this strange phenomenon further shows that the conventional atmospheric transport processes like dust storms etc. cannot explain this phenomenon. The electron microscopic study of the red particles shows fine cell structure indicat- ing their biological cell like nature. EDAX analysis shows that the major elements present in these cell like particles are carbon and oxygen. Strangely, a test for DNA using Ethidium Bromide dye fluorescence technique indicates absence of DNA in these cells. In the context of a suspected link between a meteor airburst event and the red rain, the possibility for the extraterrestrial origin of these particles from cometary fragments is discussed.

A Study on the Transport and Distribution of Atmospheric Aerosols and its Influence on Regional Meteorological Parameters over the Indian Subcontinent

This doctoral thesis addresses the growing concern about the significant changes in the climatic and weather patterns due to the aerosol loading that have taken place in the Indo Gangetic Plain(IGP)which includes most of the Northern Indian region. The study region comprises of major industrial cities in India (New Delhi, Kanpur, Allahabad, Jamshedpur and Kolkata). Northern and central parts of India are one of the most thickly populated areas in the world and have the most intensely farmed areas. Rapid increase in population and urbanization has resulted in an abrupt increase in aerosol concentrations in recent years. The IGP has a major source of coal; therefore most of the industries including numerous thermal power plants that run on coal are located around this region. They inject copious amount of aerosols into the atmosphere. Moreover, the transport of dust aerosols from arid locations is prevalent during the dry months which increase the aerosol loading in theatmosphere. The topography of the place is also ideal for the congregation of aerosols. It is bounded by the Himalayas in the north, Thar Desert in the west, the Vindhyan range in the south and Brahmaputra ridge in the east. During the non‐monsoon months (October to May) the weather in the location is dry with very little rainfall. Surface winds are weak during most of the time in this dry season. The aerosols that reach the location by means of long distance transport and from regional sources get accumulated under these favourable conditions. The increase in aerosol concentration due to the complex combination of aerosol transport and anthropogenic factors mixed with the contribution from the natural sources alters the optical properties and the life time of clouds in the region. The associated perturbations in radiative balance have a significant impact on the meteorological parameters and this in turn determines the precipitation forming process. Therefore, any change in weather which disturbs the normal hydrological pattern is alarming in the socio‐economic point of view. Hence, the main focus of this work is to determine the variation in transport and distribution of aerosols in the region and to understand the interaction of these aerosols with meteorological parameters and cloud properties.
