The Feminist Transformation of Bioethics : An Analysis of Theoretical Perspectives and Practical Applications in Feminist Bioethics

The purpose of this study is to examine how transformation is defining feminist bioethics and to determine the nature of this transformation. Behind the quest for transformation is core feminism and its political implications, namely, that women and other marginalized groups have been given unequal consideration in society and the sciences and that this situation is unacceptable and should be remedied. The goal of the dissertation is to determine how feminist bioethicists integrate the transformation into their respective fields and how they apply the potential of feminism to bioethical theories and practice. On a theoretical level, feminist bioethicists wish to reveal how current ways of knowing are based on inequality. Feminists pay special attention especially to communal and political contexts and to the power relations endorsed by each community. In addition, feminist bioethicists endorse relational ethics, a relational account of the self in which the interconnectedness of persons is important. On the conceptual level, feminist bioethicists work with beliefs, concepts, and practices that give us our world. As an example, I examine how feminist bioethicists have criticized and redefined the concept of autonomy. Feminist bioethicists emphasize relational autonomy, which is based on the conviction that social relationships shape moral identities and values. On the practical level, I discuss stem cell research as a test case for feminist bioethics and its ability to employ its methodologies. Analyzing these perspectives allowed me first, to compare non-feminist and feminist accounts of stem cell ethics and, second, to analyze feminist perspectives on the novel biotechnology. Along with offering a critical evaluation of the stem cell debate, the study shows that sustainable stem cell policies should be grounded on empirical knowledge about how donors perceive stem cell research and the donation process. The study indicates that feminist bioethics should develop the use of empirical bioethics, which takes the nature of ethics seriously: ethical decisions are provisional and open for further consideration. In addition, the study shows that there is another area of development in feminist bioethics: the understanding of (moral) agency. I argue that agency should be understood to mean that actions create desires.

Tyttöjen toinen koti : Etnografinen tutkimus tyttökulttuurista ratsastustalleilla

Horseback riding is a popular activity in Finland, especially among young women and girls. For centuries, however, horse husbandry and horse culture in Finland had been dominated by men. Nowadays it is mainly the girls who ride as a hobby and take care of the horses. The stable has evolved into an important social sphere for girls, a semi-public room of their own where they spend time together. A study of the girl culture in the riding stable offers a unique perspective as well as new information on becoming a girl and a young woman in Finland. The subject of my research is the girl culture and girls communities at the horseback riding stables. In this thesis I discuss what kind of girl-cultural sphere the stable is, how girls organize their community, and what different aspects and meanings the hobby entails for girls while they are actively engaged in the hobby. I focus on the construction of gender and girlhood and examine how these gender constructions can be theorized as gender tradition. The research material consists of the interviews of 22 stable girls from different parts of Finland and an observation period at one of the stables. The informants were from 13 to 27 years of age. The theoretical background is based on the anthropological study of folklore, girls studies, feminist theory and post-humanist viewpoints. I am interested in how girls culture and girlhood are produced performatively in the interview narration and participant observation. I concentrate on four aspects of this culture: 1) what girls do at the stable, and what kind of relationships they create with horses; 2) social relations focusing on the ways girls construct their own groups, the way their hierarchy is constructed and how they use power; 3) the norms and social control regarding social behaviour; and 4) the reasons girls give for their involvement in the hobby, and girls interest in horses in general. In this girl culture, gender norms and boundaries are not only stretched or transgressed, but the culture also re-produces the hierarchical and stereotypical ideas of gender. The traditions of gender express both the hegemonic gender system and those ideas of gender which girls resist, at least momentarily. Constructions of gender and gender tradition are constituted at the intersections of historical and contemporary expectations of what it means to be a girl. Conscious of these societal demands, girls support, reproduce, challenge, and make comments on them.

Reconciling Opposites in Organisation Studies: An Aristotelian Approach to Modernism and Post-modernism

In view of the current fragmentation in management and organisation studies, we argue that there is a need to elaborate techniques that help reconcile contradictory and superficially incommensurable standpoints. For this purpose, we draw on ‘pre-modern’ Aristotelian epistemological and methodological sources, particularly the idea of ‘saving the appearances’ (SA), not previously introduced into organisation studies. Using SA as our starting point, we outline a methodology that helps to develop reasonable and acceptable intermediary positions in contemporary debates between ‘modernism’ and ‘post-modernism’. We illustrate the functioning of SA in the case of three issues in the philosophy of science where ‘modernist’ and ‘post-modernist’ scholars seem to have incommensurable standpoints: the nature of scientific knowledge; the conception of causality; and the epistemology of practice. We show in particular how to use the logics of ‘qualification’, ‘new conception’, and ‘complementary combination’ to form the basis for mediating positions which could then be accepted by less extreme proponents of both ‘modernism’ and ‘postmodernism’.

On the discursive construction of success/failure in narratives of post-merger integration

This article concentrates on the discursive constmction of success and failure in narratives of post-merger integration. Drawing on extensive interview material from eight Finnish-Swedish mergers and acquisitions, the empirical analysis leads to distinguishing four types of discourse — 'rationalistic', 'cultural', 'role-bound' and 'individualistic' — that narrators employ in recounting their experiences. In particular, the empirical material illustrates how the discursive frameworks enable specific (di.scursive) strategies and moves for (re)framing the success/failure, justification/legitimization of one's own actions, and (re)constniction of responsibility when dealing with socio-psychological pressures associated with success/failtire. The analysis also suggests that, as a result of making use of these discursive strategies and moves, success stories are likely to lead to overly optimistic or, in the case of failure stories, overly pessimistic views on the management's ability to control these change processes. Tliese findings imply that we should take the discursive elements that both constrain our descriptions and explanations seriously, and provide opportunities for more or less intentional (re)interpretations of postmerger integration or other organizational change processes.

Resolving Ambiguities in Confused Online Tamil Characters with Post Processing Algorithms

This paper addresses the problem of resolving ambiguities in frequently confused online Tamil character pairs by employing script specific algorithms as a post classification step. Robust structural cues and temporal information of the preprocessed character are extensively utilized in the design of these algorithms. The methods are quite robust in automatically extracting the discriminative sub-strokes of confused characters for further analysis. Experimental validation on the IWFHR Database indicates error rates of less than 3 % for the confused characters. Thus, these post processing steps have a good potential to improve the performance of online Tamil handwritten character recognition.

The Impact of Cultural Factors on Post-Acquisition Integration: Domestic and Foreign Acquisitions of Finnish Companies in 1993-2004

Acquisitions are a central component of corporate strategy. They contribute to competitive advantage by offering possibilities for both cost reductions and for revenue enhancements. However, many acquisition benefits cannot be realized without a successful integration of the acquiring and the acquired firms. Previous research shows that national and organizational culture can play a major role in determining the integration outcomes. Therefore, the overall aim of the thesis is to map out and illustrate the impact mechanisms of cultural factors in post-acquisition integration in order to explain the cultural aspects of acquisitions. This study has three main contributions. First, the study shows that international and domestic acquisitions differ concerning both strategic and cultural fit. Second, the findings highlight the importance of acculturation and cultural integration in determining post-acquisition outcomes. Finally, the study uncovers several impact mechanisms that shed light to the contradictory results related to cultural differences in previous research.

Influence of substrate temperature and post-deposition heat treatment on the optical properties of SiO2 films

Silicon dioxide films are extensively used as protective, barrier and also low index films in multilayer optical devices. In this paper, the optical properties of electron beam evaporated SiO2 films, including absorption in the UV, visible and IR regions, are reported as a function of substrate temperature and post-deposition heat treatment. A comparative study of the optical properties of SiO2 films deposited in neutral and ionized oxygen is also made.

Diabetic cardiomyopathy and post-infarct ventricular remodelling : Effects of levosimendan in a rodent model of type II diabetes

Type 2 diabetes is a risk factor for the development of cardiovascular disease. Recently, the term diabetic cardiomyopathy has been proposed to describe the changes in the heart that occur in response to chronic hyperglycemia and insulin resistance. Ventricular remodelling in diabetic cardiomyopathy includes left ventricular hypertrophy, increased interstitial fibrosis, apoptosis and diastolic dysfunction. Mechanisms behind these changes are increased oxidative stress and renin-angiotensin system activation. The diabetic Goto-Kakizaki rat is a non-obese model of type 2 diabetes that exhibits defective insulin signalling. Recently two interconnected stress response pathways have been discovered that link insulin signalling, longevity, apoptosis and cardiomyocyte hypertrophy. The insulin-receptor PI3K/Ak pathway inhibits proapoptotic FOXO3a in response to insulin signalling and the nuclear Sirt1 deacetylase inhibits proapoptotic p53 and modulates FOXO3a in favour of survival and growth. --- Levosimendan is a calcium sensitizing agent used for the management of acute decompensated heart failure. Levosimendan acts as a positive inotrope by sensitizing cardiac troponin C to calcium and exerts vasodilation by opening mitochondrial and sarcolemmal ATP-sensitive potassium channels. Levosimendan has been described to have beneficial effects in ventricular remodelling after myocardial infarction. The aims of the study were to characterize whether diabetic cardiomyopathy associates with cardiac dysfunction, cardiomyocyte apoptosis, hypertrophy and fibrosis in spontaneously diabetic Goto-Kakizaki (GK) rats, which were used to model type 2 diabetes. Protein expression and activation of the Akt FOXO3a and Sirt1 p53 pathways were examined in the development of ventricular remodelling in GK rats with and without myocardial infarction (MI). The third and fourth studies examined the effects of levosimendan on ventricular remodelling and gene expression in post-MI GK rats. The results demonstrated that diabetic GK rats develop both modest hypertension and features similar to diabetic cardiomyopathy including cardiac dysfunction, LV hypertrophy and fibrosis and increased apoptotic signalling. MI induced a sustained increase in cardiomyocyte apoptosis in GK rats together with aggravated LV hypertrophy and fibrosis. The GK rat myocardium exhibited decreased Akt- FOXO3a phosphorylation and increased nuclear translocation of FOXO3a and overproduction of the Sirt1 protein. Treatment with levosimendan decreased cardiomyocyte apoptosis, senescence and LV hypertrophy and altered the gene expression profile in GK rat myocardium. The findings indicate that impaired cardioprotection via Akt FOXO3a and p38 MAPK is associated with increased apoptosis, whereas Sirt1 functions in counteracting apoptosis and the development of LV hypertrophy in the GK rat myocardium. Overall, levosimendan treatment protects against post-MI ventricular remodelling and alters the gene expression profile in the GK rat myocardium.

Parametrized tests of post-Newtonian theory using Advanced LIGO and Einstein Telescope

General relativity has very specific predictions for the gravitational waveforms from inspiralling compact binaries obtained using the post-Newtonian (PN) approximation. We investigate the extent to which the measurement of the PN coefficients, possible with the second generation gravitational-wave detectors such as the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO) and the third generation gravitational-wave detectors such as the Einstein Telescope (ET), could be used to test post-Newtonian theory and to put bounds on a subclass of parametrized-post-Einstein theories which differ from general relativity in a parametrized sense. We demonstrate this possibility by employing the best inspiralling waveform model for nonspinning compact binaries which is 3.5PN accurate in phase and 3PN in amplitude. Within the class of theories considered, Advanced LIGO can test the theory at 1.5PN and thus the leading tail term. Future observations of stellar mass black hole binaries by ET can test the consistency between the various PN coefficients in the gravitational-wave phasing over the mass range of 11-44M(circle dot). The choice of the lower frequency cutoff is important for testing post-Newtonian theory using the ET. The bias in the test arising from the assumption of nonspinning binaries is indicated.
