Luce Irigaray's Philosophy of Feminine Being : Body, Desire and Wisdom

Luce Irigaray is a Belgian-born philosopher, psychoanalyst and linguist. Irigaray s concept of woman is crucial for understanding her own work but also for examining and developing the theoretical and methodological basis of feminist theory. This thesis argues that, ultimately, Irigaray s exploration of woman s being challenges our traditional notion of philosophy as a neutral discourse and the traditional notion of ourselves as philosophizing persons or human beings. However, despite its crucial role, Irigaray s idea of woman still lacks a comprehensive explication. This is because the discourse of sexual difference is blurred by the ideas of essentialism and biologism. --- Irigaray s concept of woman has been interpreted and criticized from the perspectives of metaphysical essentialism, strategic essentialism, realist essentialism and deconstructionism. This thesis argues that a reinterpretation is necessary to account for Irigaray s claims about the the traditional woman , mimesis, the specificity of the feminine body, feminine expression and sexual difference. Moreover, any reading should account for the differences between women and avoid giving a prescriptive function to the essence of woman. --- My thesis develops a new interpretation of Irigaray s concept of woman on the basis of the phenomenology of the body. It argues that Irigaray s discourse on woman can and must be understood by an idea of existential style. Existential style is embodied, affective and spiritual and it is constituted in relation to oneself, to others and to the world. It is temporal, it evolves and changes but preserves its open unity in its transformations. Stylistic unities, such as femininity or philosophy, are constituted in and by the singulars. -- This study discusses and analyses feminine existential style as a central theme and topic of Irigaray s works and shows how her work operates as a primary and paradigmatic example of the feminine style. These tasks are performed by studying the mimetic positions available for women and by explicating the phenomenological background of Irigaray s conceptions of the philosophical method, and the lived, expressive and affective body. The critical occupation and transformation of these mimetic positions, the inquiry into the first-person pre-discursive experience, and the cultivation of feminine expressivity open up the possibility of becoming a woman writer, a woman lover and a woman philosopher. The appearance of these new feminine figures is a precondition for the realization of sexual difference. So Irigaray opens up the possibility of sexual difference by instituting and constituting a feminine subject of love and wisdom, and by problematizing the idea of a neutral and absolute subject.

A head-mounted display as a personal viewing device: Dimensions of subjective experiences

The use of head-mounted displays (HMDs) can produce both positive and negative experiences. In an effort increase positive experiences and avoid negative ones, researchers have identified a number of variables that may cause sickness and eyestrain, although the exact nature of the relationship to HMDs may vary, depending on the tasks and the environments. Other non-sickness-related aspects of HMDs, such as users opinions and future decisions associated with task enjoyment and interest, have attracted little attention in the research community. In this thesis, user experiences associated with the use of monocular and bi-ocular HMDs were studied. These include eyestrain and sickness caused by current HMDs, the advantages and disadvantages of adjustable HMDs, HMDs as accessories for small multimedia devices, and the impact of individual characteristics and evaluated experiences on reported outcomes and opinions. The results indicate that today s commercial HMDs do not induce serious sickness or eyestrain. Reported adverse symptoms have some influence on HMD-related opinions, but the nature of the impact depends on the tasks and the devices used. As an accessory to handheld devices and as a personal viewing device, HMDs may increase use duration and enable users to perform tasks not suitable for small screens. Well-designed and functional, adjustable HMDs, especially monocular HMDs, increase viewing comfort and usability, which in turn may have a positive effect on product-related satisfaction. The role of individual characteristics in understanding HMD-related experiences has not changed significantly. Explaining other HMD-related experiences, especially forward-looking interests, also requires understanding more stable individual traits and motivations.

Molecular Details of Serum Resistance of Yersinia enterocolitica

In complement activation, Factor H (FH) and C4b-binding protein (C4bp) are the key regulators that prevent the complement cascade from attacking host tissues. Some bacteria may bind and deposit these regulators on their own surfaces and thus provide themselves with an efficient means to avoid complement activation. In consequence, bacteria resist complement-mediated lysis and opsonin-dependent phagocytosis. This study has demonstrated that Y. enterocolitica, similar to many other pathogens, recruits both FH and C4bp to its surface to ensure protection against the complement-mediated killing. YadA and Ail, the most crucial serum resistance factors of Y.enterocolitica, mediate the binding of FH and C4bp. FH - YadA interaction involves multiple higher structural motifs on the YadA stalk and the short consensus repeats (SCRs) of the entire polypeptide chain of FH. The Ail binding site on FH has been located to SCRs 6 and 7. The binding site for FH on Ail, however, remains undetermined. Both YadA- and Ail-bound regulators display full cofactor activity for FI-mediated cleavage of C3b/C4b. FH/C4bp-binding characteristics do, however, differ between YadA and Ail. In addition, Ail captures the regulators only in the absence of blocking lipopolysaccharide O-antigen and outer core, whereas YadA binds FH/C4bp independent of the presence of other surface factors Independent of mode of binding, however, YadA and Ail provide Y. enterocolitica a means to avoid complement-mediated lysis, enhancing chances for the bacteria to survive in the host during various phases of infection.

Cow’s milk related gastrointestinal symptoms in adults

The purpose of this study was to evaluate subjective food-related gastrointestinal symptoms and their relation to cow’s milk by determining the genotype of adult-type hypolactasia, measuring antibodies against milk protein, and screening the most common cause for secondary hypolactasia, namely coeliac disease. The whole study group comprised 1900 adults who gave a blood sample for the study when they attended a health care centre laboratory for various reasons. Of these 1885 (99%) completed a questionnaire on food-related gastrointestinal symptoms. Study No. I evaluated the prevalence of adult-type hypolactasia and its correlation to self-reported milk induced gastrointestinal symptoms. The testing for hypolactasia was done by determination of the C/T-13910 genotypes of the study subjects. The results show that patients with the C/C-13910 genotype associated with adult type hypolactasia consume less milk than those with C/T-13910 and T/T-13910 genotypes. Study No. II evaluated the prevalence and clinical characteristics of undiagnosed coeliac disease in the whole study population with transglutaminase and endomysium antibodies and their correlation with gastrointestinal symptoms. The prevalence of coeliac disease was 2 %, which is surprisingly high. Serum transglutaminase and endomysium antibodies are valuable tools for recognising an undiagnosed coeliac disease in outpatient clinics. In the study No. III the evaluation of milk protein IgE related hypersensitivity was carried out by stratifying all 756 study subjects with milk related problems and randomly choosing 100 age and sex matched controls with no such symptoms from the rest of the original study group. In the study No. IV 400 serum samples were randomly selected for analyzing milk protein related IgA and IgG antibodies and their correlation to milk related GI-symptoms. The measurement of milk protein IgA, IgE or IgG (studies No. III and IV) did not correlate clearly to milk induced symptoms and gave no clinically significant information; hence their measurement is not encouraged in outpatient clinics. In conclusion, adult type hypolactasia is often considered the reason for gastrointestinal symptoms in adults and determination of the C/T-13910 genotypes is a practical way of diagnosing adult type hypolactasia in an outpatient setting. Undiagnosed coeliac disease, should be actively screened and diagnosed in order to apply a gluten free diet and avoid the GI-symptoms and nutritional deficiencies. Cow’s milk hypersensitivity in the adult population is difficult to diagnose since the mechanism in which it is mediated is still unclear. Measuring of cow’s milk protein specific antibodies IgE, IgA or IgG do not correlate with subjective milk-related GI-symptoms.

Medetomidiinin glukuronidaation inhibitio

Lääkeainemetabolialla tarkoitetaan entsymaattisia reaktioita, jotka muuttavat lääkeaineita paremmin elimistöstä poistuvaan muotoon. Lääkeaineet voivat vaikuttaa toistensa metaboliaan inhiboimalla tai indusoimalla metaboloivia entsyymejä. Tällaisten interaktioiden seurauksena lääkeaineen pitoisuus elimistössä voi kasvaa jopa toksiseksi tai vähentyä merkittävästi. Tämä on erityisesti ongelmana silloin, kun käytössä on useita lääkkeitä samanaikaisesti. Lääketutkimuksessa onkin keskitytty tällaisten interaktioiden ennustamiseen ja niitä yritetään välttää tai ainakin vähentää. Työssä tutkittiin medetomidiinia, jonka on äskettäin havaittu metaboloituvan UDP-glukuronosyylitransferaasien (UGT) välityksellä. Työn tarkoituksena oli löytää medetomidiinin glukuronidaatiota inhiboivia yhdisteitä. Lisäksi haluttiin selvittää mahdollisen inhibition mekanismeja. On yleistä tutkia tietyn entsyymin substraatin interaktioita muiden saman perheen entsyymien kanssa. On kuitenkin harvinaisempaa tutkia tällaisia interaktioita kahden eri entsyymiperheen välillä. Tässä työssä tutkittiin inhiboivatko mahdolliset sytokromi P450 -entsyymiä (CYP) inhiboivat yhdisteet myös medetomidiinia glukuronoivia UDP-glukuronosyylitransferaaseja. Glukuronidaation inhibitiota tutkittiin HPLC-menetelmällä, joka on kehitetty aiemmin medetomidiinin glukuronidaation tutkimiseen. Aluksi glukuronidaatiota tutkittiin ilman inhibiittoreita. Tämän jälkeen tutkittiin kolmen mahdollisen inhibiittoriyhdisteen vaikutuksia medetomidiinin glukuronidaatioon ja tuloksia verrattiin ilman inhibiittoria saatuihin tuloksiin. Kolmen tutkitun yhdisteen havaittiin inhiboivan medetomidiinin glukuronidaatiota. Tutkimuksessa havaittiin myös mielenkiintoinen ilmiö, jossa inhibiittoriyhdisteen sitoutuminen aiheutti entsyymikineettisiä muutoksia UDP-glukuronosyylitransferaasin toiminnassa. On mielenkiintoista, että samat yhdisteet inhiboivat sekä CYP- että UGT-metaboliaa. Tulosten perusteella voidaan päätellä, että jos CYP ja UGT metaboloivat samaa yhdistettä, on mahdollista että yhdisteen rakenteelliset analogit aiheuttavat interaktioita molempien entsyymien kanssa. Uusia lääkeaineita kehitettäessä onkin otettava huomioon yleisesti tunnettujen CYP-entsyymien lisäksi myös UGT:t ja niiden mahdolliset yhteisvaikutukset.

Turning the Kaleidoscope - (E)FL Educational Experience and Inquiry as Auto/biography

This book is a study on learning, teaching/counselling, and research on the two. My quest has been to find a pedagogically-motivated way of researching learning and teaching interaction, and in particular counselling, in an autonomous language-learning environment. I have tried to develop a method that would make room for lived experience, meaning-making and narrating, because in my view these all characterise learning encounters between language learners and counsellors, and learners and their peers. Lived experience as a source of meaning, telling and co-telling becomes especially significant when we try to listen to the diverse personal and academic voices of the past as expressed in autobiographical narratives. I have aimed at researching various ALMS dialogues (Autonomous Learning Modules, University of Helsinki Language Centre English course and programme), and autobiographical narratives within them, in a way that shows respect for the participants, and that is relevant, reflective and, most importantly, self-reflexive. My interest has been in autobiographical telling in (E)FL [(English as a) foreign language], both in students first-person written texts on their language- learning histories and in the sharing of stories between learners and a counsellor. I have turned to narrative inquiry in my quest and have written the thesis as an experiential narrative. In particular, I have studied learners and counsellors in one and the same story, as characters in one narrative, in an attempt to avoid the impression that I am telling yet another separate, anecdotal story, retrospectively. Through narrative, I have shed light on the subjective dimensions of language learning and experience, and have come closer to understanding the emotional aspects of learning encounters. I have questioned and rejected a distanced and objective approach to describing learning and teaching/counselling. I have argued for a holistic and experiential approach to (E)FL encounters in which there is a need to see emotion and cognition as intertwined, and thus to appreciate learners and counsellors emotionally-charged experiences as integral to their identities. I have also argued for a way of describing such encounters as they are situated in history, time, autobiography, and the learning context. I have turned my gaze on various constellations of lived experience: the data was collected on various occasions and in various settings during one course and consists of videotaped group sessions, individual counselling sessions between students and their group counsellor, biographic narrative interviews with myself, open-ended personally-inspired reflection texts written by the students about their language-learning histories, and student logs and diaries. I do not consider data collection an unproblematic occasion, or innocent practice, and I defend the integrity of the research process. Research writing cannot be separated from narrative field work and analysing and interpreting the data. The foci in my work have turned to be the following: 1) describing ALMS encounters and specifying their narrative aspects; 2) reconceptualising learner and teacher autonomy in ALMS and in (E)FL; 2) developing (E)FL methodologically through a teacher-researcher s identity work; 4) research writing as a dialogical narrative process, and the thesis as an experiential narrative. Identity and writing as inquiry, and the deeply narrative and autobiographical nature of the (E)FL teaching/counselling/researching have come to the fore in this research. Research writing as a relational activity and its implications for situated ways of knowing and knowledge turned out to be important foci. I have also focussed on the context-bound and local teacher knowledge and ways of knowing about being a teacher, and I have argued for personal ways of knowing about, and learning and studying foreign languages. I discuss research as auto/biography: as a practising counsellor I use my own life and (E)FL experience to understand and interpret the stories of the research participants even though I was not involved in their course work. The supposedly static binaries of learner/teacher, and also learner autonomy/teacher autonomy, are thus brought into the discussion. I have highlighted the infinite variability and ever-changing nature of learning and teaching English, but the book is also of relevance to foreign language education in general.
