En förutbestämd sanning : Barnamord och delaktighet i 1700-talets Finland belysta genom kön, kropp och social kontroll

The study analyses the prevention or endorsing of the crime of infanticide in Finland 1702 1807, rather than the result. Also the impacts of the female body, biology of childbirth and experiences of pregnancy are examined, together with insights from modern medical research. Circumstances are reconstructed by a critical reading of judicial records on all levels of the judicial system. In all 269 cases of infanticide and 142 accessory crimes within the jurisdiction of the Turku court of appeal are studied, with particular focus on exceptionally well recorded cases of 83 accused women and 41 women and men accused of being party to the crime. Secondary sources are medical and jurisprudential writings, the public debate on infanticide, broadsheets and letters asking the King for pardon. Infanticide was considered murder by law. Unmarried women were predetermined as the main culprits. Nevertheless, deliberate infanticides were rare and committed mostly in accomplice. The majority of the infanticides studied were cases where inexperienced and unmarried women accidentally had given birth alone and usually to a dead child. Unaware that the pain they were experiencing was in fact a labour, the accused women instinctively sought solitude to push out the child. Some misunderstood the birth as an urgent need to defecate. The unexpected delivery ended in hiding the baby without remorse. This crime was promoted by several factors in Finnish rural culture, amongst others that also married women hid their pregnancy. The immediate household members did not necessarily know about the childbirth and failed to help the woman. This typical pattern in most cases of infanticide in 18th century Finland is also recorded in modern cases of unknown pregnancies. Fear of accountability prevented witnesses testifying to the actual course of events. The truth remained elusive. With only a few exceptions, the women were sentenced to death or imprisonment. The majority of those accused of accomplice were acquitted. However, too harsh sentences for accidents affected the reporting of the crime. Criminal politics failed to curtail infanticide as the crime was unsatisfactorily addressed by law, society and the judicial system.

Poetics of Subjectivity : Existence and Expressivity in Simone de Beauvoir's Philosophy

In the last thirty years, primarily feminist scholars have drawn attention to and re-evaluated the philosophy of Simone de Beauvoir (1908 1986). Her philosophical practice has been described as non-systematic, and her literary writing has been viewed as part of her non-systematic mode of philosophising. This dissertation radically deepens the question concerning Beauvoir s philosophical motivations for turning to literature as a mode to express subjectivity. It explicates the central concepts of Beauvoir s philosophy of existence, which are subjectivity, ambiguity, paradox and temporality, and their background in the modern traditions of existential philosophy and phenomenology. It also clarifies Beauvoir s main reason to turn to literature in order to express subjectivity as both singular and universal: as a specific mode of communication, literature is able to make the universality of existence manifest in the concrete, singular and temporal texture of life. In addition, the thesis gives examples of how Beauvoir s literary works contribute to an understanding of the complexity of subjectivity. I use the expression poetics of subjectivity to refer to the systematic relation between Beauvoir s existential and phenomenological notion of subjectivity and her literary works, and to her articulations of a creative mode of using language, especially in the novel. The thesis is divided into five chapters, of which the first three investigate Beauvoir s philosophy of existence at the intersection of the modern traditions of thought that began with René Descartes and Søren Kierkegaard s intuitions about subjectivity. Chapter 1 interprets Beauvoir s notion of ambiguity, as compared to paradox, and argues that both determine her notion of existence. Chapters 2 and 3 investigate the phenomenological side of Beauvoir s philosophy through a study of her response to early French interpretations of transcendental subjectivity, especially in the works of Jean-Paul Sartre and Maurice Merleau-Ponty. My analysis shows that Edmund Husserl s distinction between different levels of subjective experience is central to Beauvoir s understanding of subjectivity and to the different ego concepts she uses. Chapter 4 is a study of Beauvoir s reflections on the expression of subjective thought, and, more specifically, her philosophical conceptions of the metaphysical novel and the autobiography as two modes of indirect communication. Chapter 5, finally, compares two modes of investigating concrete subjectivity; Beauvoir s conceptual study of femininity in Le deuxième sexe and her literary expression of subjectivity in the novel L Invitée. My analysis reveals and explicates Beauvoir s original contribution to a comprehensive understanding of the becoming and paradox of human existence: the fundamental insight that these phenomena are sexed, historically as well as imaginatively.

I konstens namn - scenen som arbetsmiljö : Arbetsplatsmobbning ur skådespelarperspektiv

Workplace bullying is a topic of current interest in Finland. Workplace bullying is found in all professions, including the artistic ones. This thesis aims to explore workplace bullying from the view of the Finland-Swedish actors as a phenomenon that within dramatic art is difficult to define due to the fact that the body and emotions of an actor constitute his or her working tools. The research aims to deepen the understanding of the actors’ working situation, and particularly of the difficulties and problems actors face when exercising their job. The research problems are: What forms of bullying are the actors exposed to? Who is bullying? How is the bullying received by the actors, and what are the possible consequences? The theoretical orientation of this thesis is based upon dialogical philosophy where phenomenology, hermeneutics and dialog meet in an orientation where the unseen is emphasized and made visible. Artistic leadership should be based upon a pedagogic understanding that by an open and equal dialog with the Other recognizes human diversity. The narrative research was undertaken by using an interview guide for the interviews with eleven actors, six women and five men with the voice of a sixth man represented by an article. The interviews, each on average 118 minutes, were recorded and transcribed. The method of discursive analysis was initiated by numerous reflective readings based on analytic induction. The inductive part of the analysis consisted of mapping out the individual experiences of bullying where after the process of finding connecting common features in the extensive material took place. The coded data was then deductively grouped together according to the research problems, and subgroups were formed for deeper description. The research findings show that workplace bullying is an everyday occurrence within the field of dramatic art. Actors are bullied by theatre managers and directors as well as by colleagues and other personnel. The main areas of bullying is depreciation of one’s professional skills, the existing jargon, sexual harassment, collective bullying and bullying because of personal qualities. A significant finding concerning this problem was the existing culture of silence. Even if actually seeing and hearing a colleague being bullied, few stood up to defend the person being bullied because of fear of retaliation. Even the person actually being the object for bullying found it difficult to take any actions.

Stanniocalcin-1 in cell stress and differentiation

Stanniocalcin-1 (STC-1) is a 56 kD homodimeric protein which was originally identified in bony fish, where it regulates calcium/phosphate homeostasis and protects against toxic hypercalcemia. STC-1 was considered unique to fish until the cloning of cDNA for human STC-1 in 1995 and mouse Stc-1 in 1996. STC-1 is conserved through evolution with human and salmon STC-1 sharing 60% identity and 80% similarity. The surprisingly high homology between mammalian and fish STC-1 and the protective actions of STC-1 in terminally differentiated neurons, originally reported by my colleagues, prompted me to further study the role of STC-1 in cell stress and differentiation. One purpose was to determine whether there is an inter-relationship between terminally differentiated cells and STC-1 expression. The study revealed an accumulation of STC-1 in mature megakaryocytes and adipocytes, i.e. postmitotic cells with limited or lost proliferative capacity. Still proliferating uninduced cells were negative for STC-1 mRNA and protein, whereas differentiating cells accumulated STC-1 in their cytoplasm. Interestingly, in liposarcomas the grade inversely correlated with STC-1 expression. Another aim was to study how STC-1 gene expression is regulated. Given that IL-6 is a cytokine with neuroprotective actions, by unknown mechanisms, we examined whether IL-6 regulates STC-1 gene expression. Treatment of human neural Paju cells with IL-6 induced a dose-dependent upregulation of STC-1 mRNA levels. This induction of STC-1 expression by IL-6 occurred mainly through the MAPK signaling pathway. Furthermore, I studied the role of IL-6-mediated STC-1 expression as a mechanism of cytoprotection conferred by hypoxic preconditioning (HOPC) in brain and heart. My findings show that Stc-1 was upregulated in brain after hypoxia treatment. In the brain of IL-6 deficient mice, however, no upregulation of Stc-1 expression was evident. After induced brain injury the STC-1 response in brains of IL-6 transgenic mice, with IL-6 overexpression in astroglial cells, was stronger than in brains of WT mice. These results indicate that IL-6-mediated expression of STC-1 is one molecular mechanism of HOPC-induced tolerance to brain ischemia. The protection conferred by HOPC in heart occurs during a bimodal time course comprising early and delayed preconditioning. Interestingly, my results showed that the expression of Stc-1 in heart was upregulated in a biphasic manner during HOPC. IL-6 deficient mice did not, however, show a similar biphasic manner of Stc-1 upregulation as did WT mice. Instead, only an early upregulation of Stc-1 expression was evident. The results suggest that the upregulation of Stc-1 during the delayed preconditioning is IL-6-dependent. The upregulated expression of Stc-1 during the early preconditioning, however, is only partly IL-6-dependent and possibly also directly mediated by HIF-1. These findings suggest that STC-1 is a pro-survival protein for terminally differentiated cells and that STC-1 expression may in fact be regulated by stress. In addition, I show that STC-1 gene upregulation, mediated in part by IL-6, is a new mechanism of protection conferred by HOPC in brain and heart. Because of its importance for fundamental biological processes, such as differentiation and cytoprotection, STC-1 may have therapeutic implications for management of stroke, neurodegenerative diseases, cancer, and obesity.

Topological Quantum Computation - An Analysis of an Anyon Model Based on Quantum Double Symmetries

There exists various suggestions for building a functional and a fault-tolerant large-scale quantum computer. Topological quantum computation is a more exotic suggestion, which makes use of the properties of quasiparticles manifest only in certain two-dimensional systems. These so called anyons exhibit topological degrees of freedom, which, in principle, can be used to execute quantum computation with intrinsic fault-tolerance. This feature is the main incentive to study topological quantum computation. The objective of this thesis is to provide an accessible introduction to the theory. In this thesis one has considered the theory of anyons arising in two-dimensional quantum mechanical systems, which are described by gauge theories based on so called quantum double symmetries. The quasiparticles are shown to exhibit interactions and carry quantum numbers, which are both of topological nature. Particularly, it is found that the addition of the quantum numbers is not unique, but that the fusion of the quasiparticles is described by a non-trivial fusion algebra. It is discussed how this property can be used to encode quantum information in a manner which is intrinsically protected from decoherence and how one could, in principle, perform quantum computation by braiding the quasiparticles. As an example of the presented general discussion, the particle spectrum and the fusion algebra of an anyon model based on the gauge group S_3 are explicitly derived. The fusion algebra is found to branch into multiple proper subalgebras and the simplest one of them is chosen as a model for an illustrative demonstration. The different steps of a topological quantum computation are outlined and the computational power of the model is assessed. It turns out that the chosen model is not universal for quantum computation. However, because the objective was a demonstration of the theory with explicit calculations, none of the other more complicated fusion subalgebras were considered. Studying their applicability for quantum computation could be a topic of further research.

Stiffer Optical Tweezers through Real-Time Feedback Control

This thesis integrates real-time feedback control into an optical tweezers instrument. The goal is to reduce the variance in the trapped bead s position, -effectively increasing the trap stiffness of the optical tweezers. Trap steering is done with acousto-optic deflectors and control algorithms are implemented with a field-programmable gate array card. When position clamp feedback control is on, the effective trap stiffness increases 12.1-times compared to the stiffness without control. This allows improved spatial control over trapped particles without increasing the trapping laser power.

Kaksikertasironnan simulointi

Mahdollisimman tarkka tieto varatun hiukkasen energianmenetyksestä sen kulkiessa näytteessä on usein hyvin olennaista varteenotettavien tutkimustulosten aikaansaamiseksi monilla eri fysiikan suuntautumisaloilla. Aihe onkin hyvin laajalti tutkittu. Kehityksen kuitenkin edetessä yhä pienempiin mittasuhteisiin ja tarkempiin arvoihin on tärkeää, että myös ionien energianmenetyksestä väliaineessa saadaan yhä tarkempaa tietoa. Takaisinsirontaspektrometriassa tarkastellaan näytteestä sironneita ammusioneja. Takaisinsironnan avulla voidaan tunnistaa näytteen sisältämät alkuaineet, selvittää syvyysjakauma ja näytteen alkuaineiden suhteelliset runsaudet. Menetelmään liittyvät ilmiöt ovat varsin monimutkaisia ja niiden teoreettinen mallintaminen siten haasteellista. Kun tavoitteena on simuloida mahdollisimman tarkasti tilannetta, jossa kiihdytetty ioni etenee näytteessä ei analyyttinen ratkaisumalli välttämättä ole paras vaihtoehto. Tilannetta kuvaamaan onkin kehitetty useita eri laskennallisia menetelmiä. Tässä työssä tarkasteltiin sitä kuinka paljon kaksikertasironnan huomioon ottaminen vaikuttaa tuloksiin takaisinsirontaa simuloitaessa. Useimmat takaisinsironnan mallinnusohjelmat ottavat huomioon ainoastaan yksikertasironnan. Tämä on varsin ymmärrettävää, sillä jo toisen sirontatapahtuman huomioon ottaminen ja mallintaminen analyyttisesti lisää huomattavasti simulaation laskutapahtumien lukumäärää ja hidastaa siten itse simulaatiota. Työtä varten kirjoitettiin ohjelma, jolla simuloituja tuloksia verrattiin sekä näytteistä mitattuihin että toisella simulaatio-ohjelmalla tuotettuihin spektreihin. Vertailusta kävi selvästi ilmi kaksikertasironnan merkitys takaisinsirontaa simuloitaessa. Yksikertasironnan tuoma informaatio päättyy energiaan, jolla näytteen takareunasta sironnut ioni havaitaan ilmaisimessa. Toisen sirontatapahtuman huomioon ottaminen tuo lisäinformaatiota etenkin spektrin häntäalueella. Laaditulla ohjelmalla pystyttiin nyt käsittelemään ainoastaan erikoistapausta, jossa ionisuihku ammuttiin kohtisuoraan näytteeseen. Looginen jatkotoimenpide työn parissa olisi laajentaa ohjelma käsittämään muutkin ionisuihkun tulokulmat.

Shokkikiihdytys Auringon koronassa

Planeettainvälisessä avaruudessa havaitaan runsaasti Auringosta peräisin olevia korkeaenergiaisia hiukkasia. Havainnot voidaan jakaa karkeasti lyhyt- ja pitkäkestoisiin. Yleisin selitys jälkimmäisille on diffusiivinen shokkikiihdytys koronan massapurkausten edellään työntämissä shokkiaalloissa. Hiukkaset siroavat shokin turbulentista sähkömagneettisesta kentästä ja saavat lisää energiaa ylittäessään shokkirintaman monta kertaa. Kiihdytys alkaa koronassa ja jatkuu useiden päivien ajan massapurkauksen liikkuessa poispäin Auringosta. Havaintojen mukaan koronassa tapahtuva kiihdytys, jossa protonit voivat saavuttaa jopa 1 GeV suuruusluokkaa olevan energian, tapahtuu minuuttien aikaskaaloissa. Korkeaenergiaisten hiukkasten energiaspektri on tyypillisesti potenssilaki dN/dE ~ E^{-sigma}, missä sigma on lähellä ykköstä oleva vakio. Opinnäytteessä esitellään diffusiivisen shokkikiihdytyksen teoria ja tutkitaan kiihdytystä testihiukkassimulaatiolla. Koronan aktiivista aluetta mallinnetaan yksinkertaistetulla magneettikentällä. Simulaatiossa lasketaan tasomaisen shokin eteen injektoitujen protonien ratoja siihen asti, kun ne joko osuvat Auringon pintaan tai karkaavat planeettainväliseen avaruuteen. Lopputuloksista lasketuista statistiikoista etsitään kiihdytykseen vaikuttavia tekijöitä. Saatujen tuloksien perusteella koronan magneettikentän geometrialla on suuri merkitys saavutettavaan energiaan. Tehokkainta kiihdytys on geometrioissa, joissa shokki on lähes poikittainen. Erityisesti sironnan ei tarvitse olla voimakasta suurten energioiden saavuttamiseksi. Sen vaikutus näyttäisi olevan enneminkin jakaumafunktion isotropisointi, jolloin energiaspektristä tulee potenssilakimuotoinen.
