It's Complicated

The closing chapter of an extended body of work investigating gendered engagements with the [mostly male] modernist canon, It’s Complicated utilises humour and explores the dynamics of romantic relationships as methods and metaphors for critique. For a single weekend, Courtney takes a final look at her fervent relationship with the history of Western modernism, and considers whether it is the end of the affair.

It's complicated: Romancing the [male] modernist canon

This research project proposes a model of dialogue between the [predominantly male] modernist canon and models of feminist resistance. Employing a practice based methodology that utilises humour as a method for ironic deconstruction as well as a feminist methodology of revision, critique, and dialogic exchange; the resulting body of work disrupts and augments the modernist canon. Making intimate relationships explicit, the artworks explor collaborative and faux-llaborative processes to form a series of tentative gestures that refute notions of mastery and control. The accompanying exegesis contextualises this work by placing the research and the outputs amongst the field.

Complicated Presence : The Unity of Being in Parmenides and Heidegger

The attempt to refer meaningful reality as a whole to a unifying ultimate principle - the quest for the unity of Being - was one of the basic tendencies of Western philosophy from its beginnings in ancient Greece up to Hegel's absolute idealism. However, the different trends of contemporary philosophy tend to regard such a speculative metaphysical quest for unity as obsolete. This study addresses this contemporary situation on the basis of the work of Martin Heidegger (1889-1976). Its methodological framework is Heidegger's phenomenological and hermeneutical approach to the history of philosophy. It seeks to understand, in terms of the metaphysical quest for unity, Heidegger's contrast between the first (Greek) beginning or "onset" (Anfang) of philosophy and another onset of thinking. This other onset is a possibility inherent in the contemporary situation in which, according to Heidegger, the metaphysical tradition has developed to its utmost limits and thereby come to an end. Part I is a detailed interpretation of the surviving fragments of the Poem of Parmenides of Elea (fl. c. 500 BC), an outstanding representative of the first philosophical beginning in Heidegger's sense. It is argued that the Poem is not a simple denial of apparent plurality and difference ("mortal acceptances," doxai) in favor of an extreme monism. Parmenides' point is rather to show in what sense the different instances of Being can be reduced to an absolute level of truth or evidence (aletheia), which is the unity of Being as such (to eon). What in prephilosophical human experience is accepted as being is referred to the source of its acceptability: intelligibility as such, the simple and undifferentiated presence to thinking that ultimately excludes unpresence and otherness. Part II interprets selected key texts from different stages in Heidegger's thinking in terms of the unity of Being. It argues that one aspect of Heidegger's sustained and gradually deepening philosophical quest was to think the unity of Being as singularity, as the instantaneous, context-specific, and differential unity of a temporally meaningful situation. In Being and Time (1927) Heidegger articulates the temporal situatedness of the human awareness of meaningful presence. His later work moves on to study the situational correlation between presence and the human awareness. Heidegger's "postmetaphysical" articulation seeks to show how presence becomes meaningful precisely as situated, in an event of differentiation from a multidimensional context of unpresence. In resigning itself to this irreducibly complicated and singular character of meaningful presence, philosophy also faces its own historically situated finitude. This resignation is an essential feature of Heidegger's "other onset" of thinking.

Corneal recovery after uncomplicated and complicated PRK and LASIK

Refractive errors, especially myopia, seem to increase worldwide. Concurrently, the number of surgical refractive corrections has increased rapidly, with several million procedures performed annually. However, excimer laser surgery was introduced after a limited number of studies done with animals and to date there still are only few long-term follow-up studies of the results. The present thesis aims to evaluate the safety and functional outcome of, as well as to quantify the cellular changes and remodelling in the human cornea after, photorefractive keratectomy (PRK) and laser assisted in situ keratomileusis (LASIK). These procedures are the two most common laser surgical refractive methods. In Study I, myopic ophthalmic residents at Helsinki University Eye Hospital underwent a refractive correction by PRK. Five patients were followed up for 6 months to assess their subjective experience in hospital work and their performance in car driving simulator and in other visuomotor functions. Corneal morphological changes were assessed by in vivo confocal microscopy (ivCM). Study II comprised 14 patients who had undergone a PRK operation in 1993-1994. Visual acuity was examined and ivCM examinations performed 5 years postoperatively. In Study III 15 patients received LASIK refractive correction for moderate to high myopia (-6 - -12 D). Their corneal recovery was followed by ivCM for 2 years. Diffuse lamellar keratitis (DLK) is a common but variable complication of LASIK. Yet, its aetiology remains unknown. In Study IV we examined six patients who had developed DLK as a consequence of formation of an intraoperative or post-LASIK epithelial defect, to assess the corneal and conjunctival inflammatory reaction. In the whole series, the mean refractive correction was -6.46 diopters. The best spectacle corrected visual acuity (BSCVA) improved in 30 % of patients, whereas in four patients BSCVA decreased slightly. The mean achieved refraction was 0.35 D undercorrected. After PRK, the stromal scar formation was highest at 2 to 3 months postoperatively and subsequently decreased. At 5 years increased reflectivity in the subepithelial stroma was observed in all patients. Interestingly, no Bowman s layer was detected in any patient. Subbasal nerve fiber bundle(snfb) regeneration could be observed already at 2 months in 2 patients after PRK. After 5 years, all corneas presented with snfb, the density of which, however, was still lower than in control corneas. LASIK induced a hypocellular area on both sides of the flap interface. A decrease of the most anterior keratocyte density was also observed. In the corneas that developed DLK, inflammatory cell-type objects were present in the flap interface in half of the patients. The other patients presented only with keratocyte activation and highly reflective extracellular matrix. These changes resolved completely with medication and time. Snfb regeneration was first detected at one month post-LASIK, but still after two years the density of snfb, however, was only 64 % of the preoperative values. The performance of ophthalmological examinations and microsurgery without spectacles was easier postoperatively, which was appreciated by the residents. Both PRK and LASIK showed moderate to good accuracy and high safety. In terms of visual perception and subjective evaluation, few patients stated any complaints in the whole series of studies. Instead, the majority of patients experienced a marked improvement in everyday life and work performance. PRK and LASIK have shown similar results, with good long term morphological healing. It seems evident that, even without the benefit of over-20-year follow-up results, these procedures are sufficiently safe and accurate for refractive corrections and corneal reshaping.

Computer-Aided Reliability Analysis of Complicated Networks

A computer-aided procedure is described for analyzing the reliability of complicated networks. This procedure breaks down a network into small subnetworks whose reliability can be more readily calculated. The subnetworks which are searched for are those with only two nodes; this allows the original network to be considerably simplified.

Boundary knot method for 2D and 3D Helmholtz and convection-diffusion problems under complicated geometry

The boundary knot method (BKM) of very recent origin is an inherently meshless, integration-free, boundary-type, radial basis function collocation technique for the numerical discretization of general partial differential equation systems. Unlike the method of fundamental solutions, the use of non-singular general solution in the BKM avoids the unnecessary requirement of constructing a controversial artificial boundary outside the physical domain. The purpose of this paper is to extend the BKM to solve 2D Helmholtz and convection-diffusion problems under rather complicated irregular geometry. The method is also first applied to 3D problems. Numerical experiments validate that the BKM can produce highly accurate solutions using a relatively small number of knots. For inhomogeneous cases, some inner knots are found necessary to guarantee accuracy and stability. The stability and convergence of the BKM are numerically illustrated and the completeness issue is also discussed.

Data Analysis on Complicated Construction Data Sources: Vision, Research, and Recent Developments

Compared with construction data sources that are usually stored and analyzed in spreadsheets and single data tables, data sources with more complicated structures, such as text documents, site images, web pages, and project schedules have been less intensively studied due to additional challenges in data preparation, representation, and analysis. In this paper, our definition and vision for advanced data analysis addressing such challenges are presented, together with related research results from previous work, as well as our recent developments of data analysis on text-based, image-based, web-based, and network-based construction sources. It is shown in this paper that particular data preparation, representation, and analysis operations should be identified, and integrated with careful problem investigations and scientific validation measures in order to provide general frameworks in support of information search and knowledge discovery from such information-abundant data sources.
