Knowledge Transfer within Western Multinationals' Subsidiary Units in China and Finland - The Impact of Headquarter Control Mechanisms, Subsidiary Location and Social Capital (summary section only)

It is suggested that the ability and practices of how the multinational corporation (MNC) manages knowledge transfer among its geographically dispersed subsidiary units are crucial for the building and development of firm competitive advantage. However, cross-border transfer of valuable organizational knowledge is likely to be problematic and laborious, especially within diversified and differentiated MNCs. Using data collected from 164 western multinational companies’ subsidiary units located in China and Finland, this study aims to investigate cross-border knowledge transfer within the MNC. It explores a number of factors that influence the transfer of knowledge among units in the differentiated MNC. The study consists of five individual papers. Paper 1 investigates a range of organizational mechanisms that may positively influence a subsidiary’s propensity to undertake knowledge transfers to other parts of the corporation. Paper 2 explores the impact of subsidiary location on the motivational dispositions of knowledge receiving units to value and accept knowledge from subsidiaries located in economically less advanced countries. Paper 3 examines the influence of social capital variables on knowledge transfer in dyadic relationships between foreign-owned subsidiaries and their sister and patent units. Paper 4 provides some initial insights into potentially different effects of trust and shared vision in intra-organizational vs. inter-organizational relationships. Using a case study setting, Paper 5 explores means and mechanisms used in transferring human resource management practices to Western MNCs’ business units in China from a cultural perspective. The results of the study show that MNC management through choices regarding organizational controls can encourage and enhance corporate-internal knowledge transfer. It also finds evidence that more knowledge is transferred from subsidiaries located in an industrialized country (e.g., Finland) than subsidiaries located in a developing country (e.g., China). While the study has highlighted the importance of social capital in promoting knowledge transfer, it has also uncovered some new findings that the effect of trust and shared vision may be contingent upon different contexts. Finally, in Paper 5, a number of mechanisms used in transferring selected HRM practices and competences to the Chinese business units have been identified. The findings suggest that cultural differences should be taken into consideration in the choice and use of different transfer mechanisms.

Towards Explaining the Use of Control Mechanisms in Foreign Subsidiaries of MNCs (summary section only)

Control is central to management and there is already a considerable body of research on control. However, the emergence and growth of multinational corporations (MNCs) has renewed the interest in control, as MNCs are complex (often large) organizations that face circumstances beyond those of national business organizations. The geographical dispersion of MNC activities means that the headquarters controls subsidiaries that differ with regard to power and that are embedded in different cultural, political, legal and educational systems. Foreign subsidiary control also takes place across language boundaries and physical (i.e. geographical) distances. In face of these challenges, how are foreign subsidiaries controlled? The thesis explores different types of control mechanisms and attempts to explain the degree to which they are used to control foreign subsidiaries. It contributes to existing knowledge on control by exploring how five different control mechanisms are related to each other. Previous research has tended to focus only on one or two control mechanisms and seldom has their effect on each other been explored. The thesis also contributes by including two central aspects of the MNC that have been neglected in much of the research on foreign subsidiary control: language competence of subsidiary staff and physical distance between the headquarters and its subsidiaries. The findings indicate that specific control mechanisms should not be studied in isolation as there are intricate relationships among the different control mechanisms. Language competence of the subsidiary staff can furthermore affect the type and degree of control that the headquarters can exercise over a subsidiary. The findings also indicate that changes in the physical distance between subsidiaries and its headquarters (i.e. a relocation of the headquarters as part of a restructuring process) can have great consequences for the headquarters-subsidiary relationship.

Forest governance and climate change adaptation : Case studies of four African countries

Africa is threatened by climate change. The adaptive capacity of local communities continues to be weakened by ineffective and inefficient livelihood strategies and inappropriate development interventions. One of the greatest challenges for climate change adaptation in Africa is related to the governance of natural resources used by vulnerable poor groups as assets for adaptation. Practical and good governance activities for adaptation in Africa is urgently and much needed to support adaptation actions, interventions and planning. The adaptation role of forests has not been as prominent in the international discourse and actions as their mitigation role. This study therefore focused on the forest as one of the natural resources used for adaptation. The general objective of this research was to assess the extent to which cases of current forest governance practices in four African countries Burkina Faso, The Democratic Republic of Congo (DRC), Ghana and Sudan are supportive to the adaptation of vulnerable societies and ecosystems to impacts of climate change. Qualitative and quantitative analyses from surveys, expert consultations and group discussions were used in analysing the case studies. The entire research was guided by three conceptual sets of thinking forest governance, climate change vulnerability and ecosystem services. Data for the research were collected from selected ongoing forestry activities and programmes. The study mainly dealt with forest management policies and practices that can improve the adaptation of forest ecosystems (Study I) and the adaptive capacity through the management of forest resources by vulnerable farmers (Studies II, III, IV and V). It was found that adaptation is not part of current forest policies, but, instead, policies contain elements of risk management practices, which are also relevant to the adaptation of forest ecosystems. These practices include, among others, the management of forest fires, forest genetic resources, non-timber resources and silvicultural practices. Better livelihood opportunities emerged as the priority for the farmers. These vulnerable farmers had different forms of forest management. They have a wide range of experience and practical knowledge relevant to ensure and achieve livelihood improvement alongside sustainable management and good governance of natural resources. The contributions of traded non-timber forest products to climate change adaptation appear limited for local communities, based on their distribution among the stakeholders in the market chain. Plantation (agro)forestry, if well implemented and managed by communities, has a high potential in reducing socio-ecological vulnerability by increasing the food production and restocking degraded forest lands. Integration of legal arrangements with continuous monitoring, evaluation and improvement may drive this activity to support short, medium and long term expectations related to adaptation processes. The study concludes that effective forest governance initiatives led by vulnerable poor groups represent one practical way to improve the adaptive capacities of socio-ecological systems against the impacts of climate change in Africa.

Molecular mechanisms of hypertension-induced heart failure : Experimental studies with special emphasis on local renin-angiotensin system, cardiac metabolism and levosimendan

Hypertension is a major risk factor for stroke, ischaemic heart disease, and the development of heart failure. Hypertension-induced heart failure is usually preceded by the development of left ventricular hypertrophy (LVH), which represents an adaptive and compensatory response to the increased cardiac workload. Biomechanical stress and neurohumoral activation are the most important triggers of pathologic hypertrophy and the transition of cardiac hypertrophy to heart failure. Non-clinical and clinical studies have also revealed derangements of energy metabolism in hypertensive heart failure. The goal of this study was to investigate in experimental models the molecular mechanisms and signalling pathways involved in hypertension-induced heart failure with special emphasis on local renin-angiotensin-aldosterone system (RAAS), cardiac metabolism, and calcium sensitizers, a novel class of inotropic agents used currently in the treatment of acute decompensated heart failure. Two different animal models of hypertensive heart failure were used in the present study, i.e. hypertensive and salt-sensitive Dahl/Rapp rats on a high salt diet (a salt-sensitive model of hypertensive heart failure) and double transgenic rats (dTGR) harboring human renin and human angiotensinogen genes (a transgenic model of hypertensive heart failure with increased local RAAS activity). The influence of angiotensin II (Ang II) on cardiac substrate utilization and cardiac metabolomic profile was investigated by using gas chromatography coupled to time-of-flight mass spectrometry to detect 247 intermediary metabolites. It was found that Ang II could alter cardiac metabolomics both in normotensive and hypertensive rats in an Ang II receptor type 1 (AT1)-dependent manner. A distinct substrate use from fatty acid oxidation towards glycolysis was found in dTGR. Altered cardiac substrate utilization in dTGR was associated with mitochondrial dysfunction. Cardiac expression of the redox-sensitive metabolic sensor sirtuin1 (SIRT1) was increased in dTGR. Resveratrol supplementation prevented cardiovascular mortality and ameliorated Ang II-induced cardiac remodeling in dTGR via blood pressure-dependent pathways and mechanisms linked to increased mitochondrial biogenesis. Resveratrol dose-dependently increased SIRT1 activity in vitro. Oral levosimendan treatment was also found to improve survival and systolic function in dTGR via blood pressure-independent mechanisms, and ameliorate Ang II-induced coronary and cardiomyocyte damage. Finally, using Dahl/Rapp rats it was demonstrated that oral levosimendan as well as the AT1 receptor antagonist valsartan improved survival and prevented cardiac remodeling. The beneficial effects of levosimendan were associated with improved diastolic function without significantly improved systolic changes. These positive effects were potentiated when the drug combination was administered. In conclusion, the present study points to an important role for local RAAS in the pathophysiology of hypertension-induced heart failure as well as its involvement as a regulator of cardiac substrate utilization and mitochondrial function. Our findings suggest a therapeutic role for natural polyphenol resveratrol and calcium sensitizer, levosimendan, and the novel drug combination of valsartan and levosimendan, in prevention of hypertension-induced heart failure. The present study also provides a better understanding of the pathophysiology of hypertension-induced heart failure, and may help identify potential targets for novel therapeutic interventions.

Identification of corona discharge-induced SF6 oxidation mechanisms using SF6/18O2/H216O and SF6/16O2/H218O gas mixtures

The absolute yields of gaseous oxyfluorides SOF2, SO2F2, and SOF4 from negative, point-plane corona discharges in pressurized gas mixtures of SF6 with O2 and H2O enriched with18O2 and H2 18O have been measured using a gas chromatograph-mass spectrometer. The predominant SF6 oxidation mechanisms have been revealed from a determination of the relative18O and16O isotope content of the observed oxyfluoride by-product. The results are consistent with previously proposed production mechanisms and indicate that SOF2 and SO2F2 derive oxygen predominantly from H2O and O2, respectively, in slow, gas-phase reactions involving SF4, SF3, and SF2 that occur outside of the discharge region. The species SOF4 derives oxygen from both H2O and O2 through fast reactions in the active discharge region involving free radicals or ions such as OH and O, with SF5 and SF4.

Hyvän hallinnon muunnelmat : Julkisoikeudellinen tutkimus

This doctoral thesis analyses the concepts of good governance and good administration. The hypothesis is that the concepts are radically indeterminate and over-inclusive. In the study the mechanisms of this indeterminacy are examined: why are the concepts indeterminate; how does the indeterminacy work and, indeed, is it by any means plausible to try to define the concepts in a closed way? Therefore, the study focuses on various current perspectives, from which the concepts of good governance and good administration are relevant and what kind of discursive contents they may include. The approach is both legal (a right to good administration) and one of moral philosophy and discourse analysis. It appears that under the meta-discourse of good governance and good administration there are different sub-discourses: at least a legal sub-discourse, a moral/ethical sub-discourse and sub-discourses concerning economic effectiveness and the promotion of societal and economic development. The main claim is that the various sub-discourses do not necessarily identify each other s value premises and conceptual underpinnings: for which value could the attribute good be substituted in different discourses (for example, good as legal, good as ethical and so on)? The underlying presumption is, of course, that values are ultimately subjective and incommensurable. One possible way of trying to resolve the dynamics of possible discourse collisions is to employ the systems theory approach. Can the different discourses be interpreted as autopoietic systems, which create and change themselves according to their own criteria and are formed around a binary code? Can the different discourses be reconciled or are they indifferent or hostile towards each other? Is there a hegemonic super discourse or is the construction of a correct meaning purely contextual? The questions come back to the notions of administration and governance themselves the terms the good in its polymorphic ways is attempting to define. Do they engage different political rationalities? It can be suggested that administration is labelled by instrumental reason, governance by teleological reason. In the final analysis, the most crucial factor is that of power. It is about a Schmittian battle of concepts; how meanings are constructed in the interplay between conceptual ambiguity and social power. Thus, the study deals with administrative law, legal theory and the limits of law from the perspective of revealing critique.

Design of Single-Input-Single-Output Compliant Mechanisms for Practical Applications Using Selection Maps

We present an interactive map-based technique for designing single-input-single-output compliant mechanisms that meet the requirements of practical applications. Our map juxtaposes user-specifications with the attributes of real compliant mechanisms stored in a database so that not only the practical feasibility of the specifications can be discerned quickly but also modifications can be done interactively to the existing compliant mechanisms. The practical utility of the method presented here exceeds that of shape and size optimizations because it accounts for manufacturing considerations, stress limits, and material selection. The premise for the method is the spring-leverage (SL) model, which characterizes the kinematic and elastostatic behavior of compliant mechanisms with only three SL constants. The user-specifications are met interactively using the beam-based 2D models of compliant mechanisms by changing their attributes such as: (i) overall size in two planar orthogonal directions, separately and together, (ii) uniform resizing of the in-plane widths of all the beam elements, (iii) uniform resizing of the out-of-plane thick-nesses of the beam elements, and (iv) the material. We present a design software program with a graphical user interface for interactive design. A case-study that describes the design procedure in detail is also presented while additional case-studies are posted on a website. DOI:10.1115/1.4001877].

Mechanisms of azole resistance and carcinogenic acetaldehyde production in chronic mucosal candidosis

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED, APS1) is an autoimmune disease caused by a loss-of function mutation in the autoregulator gene (AIRE). Patients with APECED suffer from chronic mucocutaneous candidosis (CMC) of the oral cavity and oesophagus often since early childhood. The patients are mainly colonized with Candida albicans and decades of exposure to antifungal agents have lead to the development of clinical and microbiological resistance in the treatment of CMC in the APECED patient population in Finland. A high incidence of oral squamous cell carcinoma is associated with oral CMC lesions in the APECED patients over the age of 25. The overall aim of this study was firstly, to investigate the effect of long-term azole exposure on the metabolism of oral C. albicans isolates from APECED patients with CMC and secondly, to analyse the specific molecular mechanisms that are responsible for these changes. The aim of the first study was to examine C. albicans strains from APECED patients and the level of cross-resistance to miconazole, the recommended topical compound for the treatment of oral candidosis. A total of 16% of the strains had decreased susceptibility to miconazole and all of these isolates had decreased susceptibility to fluconazole. Miconazole MICs also correlated with MICs to voriconazole and posaconazole. A significant positive correlation between the years of miconazole exposure and the MICs to azole antifungal agents was also found. These included azoles the patients had not been exposed to. The aim of our second study was to determine if the APECED patients are continuously colonized with the same C. albicans strains despite extensive antifungal treatment and to gain a deeper insight into the genetic changes leading to azole resistance. The strains were typed using MLST and our results confirmed that all patients were persistently colonized with the same or a genetically related strain despite antifungal treatment between isolations. No epidemic strains were found. mRNA expression was analysed by Northern blotting, protein level by western blotting, and TAC1 and ERG11 genes were sequenced. The main molecular mechanisms resulting in azole resistance were gain-of-function mutations in TAC1 leading to over expression of CDR1 and CDR2, genes linked to azole resistance. Several strains had also developed point mutations in ERG11, another gene linked to azole resistance. In the third study we used gas chromatography to test whether the level of carcinogenic acetaldehyde produced by C. albicans strains isolated from APECED patients were different from the levels produced by strains isolated from healthy controls and oral carcinoma patients. Acetaldehyde is a carcinogenic product of alcohol fermentation and metabolism in microbes associated with cancers of the upper digestive tract. In yeast, acetaldehyde is a by-product of the pyruvate bypass that converts pyruvate into acetyl-CoA during fermentation. Our results showed that strains isolated from APECED patients produced mutagenic levels of acetaldehyde in the presence of glucose (100mM, 18g/l) and the levels produced were significantly higher than those from strains isolated from controls and oral carcinoma patients. All strains in the study, however, were found to produce mutagenic levels of acetaldehyde in the presence of ethanol (11mM). The glucose and ethanol levels used in this study are equivalent to those found in food and beverages and our results highlight the role of dietary sugars and ethanol on carcinogenesis. The aims of our fourth study were to research the effect of growth conditions in the levels of acetaldehyde produced by C. albicans and to gain deeper insight into the role of different genes in the pyruvate-bypass in the production of high acetaldehyde levels. Acetaldehyde production in the presence of glucose increased by 17-fold under moderately hypoxic conditions compared to the levels produced under normoxic conditions. Under moderately hypoxic conditions acetaldehyde levels did not correlate with the expression of ADH1 and ADH2, genes catalyzing the oxidation of ethanol to acetaldehyde, or PDC11, the gene catalyzing the oxidation of pyruvate to acetaldehyde but correlated with the expression of down-stream genes ALD6 and ACS1. Our results highlight a problem where indiscriminate use of azoles may influence azole susceptibility and lead to the development of cross-resistance. Despite clinically successful treatment leading to relief of symptoms, colonization by C. albicans strains is persistent within APECED patients. Microevolution and point mutations that occur in strains may lead to the development of azole-resistant isolates and metabolic changes leading to increased production of carcinogenic acetaldehyde.

Nationalism Circumscribed : Transnational Governance of Minority Rights in Post-Cold War Europe

For the past two centuries, nationalism has been among the most influential legitimizing principles of political organization. According to its simple definition, nationalism is a principle or a way of thinking and acting which holds that the world is divided into nations, and that national and political units should be congruent. Nationalism can thus be divided into two aspects: internal and external. Internally, the political units, i.e., states, should be made up of only one nation. Externally each nation-state should be sovereign. Transnational national governance of rights of national minorities violates both these principles. This study explores the formation, operation, and effectiveness of the European post-Cold War minorities system. The study identifies two basic approaches to minority rights: security and justice. These approaches have been used to legitimize international minority politics and they also inform the practice of transnational governance. The security approach is based on the recognition that the norm of national self-determination cannot be fulfilled in all relevant cases, and so minority rights are offered as a compensation to the dissatisfied national groups, reducing their aspiration to challenge the status quo. From the justice perspective, minority rights are justified as a compensatory strategy against discrimination caused by majority nation-building. The research concludes that the post-Cold War minorities system was justified on the basis of a particular version of the security approach, according to which only Eastern European minority situations are threatening because of the ethnic variant of nationalism that exists in that region. This security frame was essential in internationalising minority issues and justifying the swift development of norms and institutions to deal with these issues. However, from the justice perspective this approach is problematic, since it justified double standards in European minority politics. Even though majority nation-building is often detrimental to minorities also in Western Europe, Western countries can treat their minorities more or less however they choose. One of the main contributions of this thesis is the detailed investigation of the operation of the post-Cold War minorities system. For the first decade since its creation in the early 1990s, the system operated mainly through its security track, which is based on the field activities of the OSCE that are supported by the EU. The study shows how the effectiveness of this track was based on inter-organizational cooperation in which various transnational actors compensate for each other s weaknesses. After the enlargement of the EU and dissolution of the membership conditionality this track, which was limited to Eastern Europe from the start, has become increasingly ineffective. Since the EU enlargement, the focus minorities system has shifted more and more towards its legal track, which is based on the Framework Convention for the Protection of National Minorities (Council of Europe). The study presents in detail how a network of like-minded representatives of governments, international organizations, and independent experts was able strengthen the framework convention s (originally weak) monitoring system considerably. The development of the legal track allows for a more universal and consistent, justice-based approach to minority rights in contemporary Europe, but the nationalist principle of organization still severely hinders the materialization of this possibility.

A metabolomic approach to studying mechanisms of polymeric gene delivery to retinal pigment epithelial cells

Tiivistelmä ReferatAbstract Metabolomics is a rapidly growing research field that studies the response of biological systems to environmental factors, disease states and genetic modifications. It aims at measuring the complete set of endogenous metabolites, i.e. the metabolome, in a biological sample such as plasma or cells. Because metabolites are the intermediates and end products of biochemical reactions, metabolite compositions and metabolite levels in biological samples can provide a wealth of information on on-going processes in a living system. Due to the complexity of the metabolome, metabolomic analysis poses a challenge to analytical chemistry. Adequate sample preparation is critical to accurate and reproducible analysis, and the analytical techniques must have high resolution and sensitivity to allow detection of as many metabolites as possible. Furthermore, as the information contained in the metabolome is immense, the data set collected from metabolomic studies is very large. In order to extract the relevant information from such large data sets, efficient data processing and multivariate data analysis methods are needed. In the research presented in this thesis, metabolomics was used to study mechanisms of polymeric gene delivery to retinal pigment epithelial (RPE) cells. The aim of the study was to detect differences in metabolomic fingerprints between transfected cells and non-transfected controls, and thereafter to identify metabolites responsible for the discrimination. The plasmid pCMV-β was introduced into RPE cells using the vector polyethyleneimine (PEI). The samples were analyzed using high performance liquid chromatography (HPLC) and ultra performance liquid chromatography (UPLC) coupled to a triple quadrupole (QqQ) mass spectrometer (MS). The software MZmine was used for raw data processing and principal component analysis (PCA) was used in statistical data analysis. The results revealed differences in metabolomic fingerprints between transfected cells and non-transfected controls. However, reliable fingerprinting data could not be obtained because of low analysis repeatability. Therefore, no attempts were made to identify metabolites responsible for discrimination between sample groups. Repeatability and accuracy of analyses can be influenced by protocol optimization. However, in this study, optimization of analytical methods was hindered by the very small number of samples available for analysis. In conclusion, this study demonstrates that obtaining reliable fingerprinting data is technically demanding, and the protocols need to be thoroughly optimized in order to approach the goals of gaining information on mechanisms of gene delivery.
