Signifying Angels : Analyses and Interpretations of Rautavaara s Instrumental Compositions

The subject of doctoral thesis is the analysis and interpretation of instrumental pieces composed by Einojuhani Rautavaara (b. 1928) that have been given angelic titles: Archangel Michael Fighting the Antichrist from the suite Icons (1955)/Before the Icons (2006), Angels and Visitations (1978), the Double Bass Concerto Angel of Dusk (1980), Playgrounds for Angels (1981)and the Seventh Symphony Angel of Light (1994). The aim of the work is to find those musical elements common to these pieces that distinguish them from Rautavaara s other works and to determine if they could be thought of as a series. I prove that behind the common elements and titles stands the same extramusical idea the figure of an angel that the composer has described in his commentaries. The thesis is divided into three parts. Since all of the compositions possess titles that refer to the spiritual symbol of an angel, the first part offers a theoretical background to demonstrate the significant role played by angels in various religions and beliefs, and the means by which music has attempted to represent this symbol throughout history. This background traces also Rautavaara s aesthetic attitude as a spiritual composer whose output can be studied with reference to his extramusical interests including literature, psychology, painting, philosophy and myths. The second part focuses on the analysis of the instrumental compositions with angelic titles, without giving consideration to their commentaries and titles. The analyses concentrate in particular on those musical features that distinguish these pieces from Rautavaara s other compositions. In the third part these musical features are interpreted as symbols of the angel through comparison with vocal and instrumental pieces which contain references to the character of an angel, structures of mythical narration, special musical expressions, use of instruments and aspects of brightness. Finally I explore the composer s interpretative codes, drawing on Rilke s cycle of poems Ten Duino Elegies and Jung s theory of archetypes, and analyze the instrumental pieces with angelic titles in the light of the theory of musical ekphrasis.

Moderneja ryijyjä, metritavaraa ja käsityötä : Tekstiilitaide ja nykyaikaistuva taideteollisuus Suomessa maailmansotien välisenä aikana

Modern ryijys, fabric by the yard and handicrafts. Finnish textile art and modernizing applied art during the inter-war years Textile art was in the 1920s and 1930s in the front rank of Finnish applied art and design. Modern ryijys, tapestries and fabrics by the yard by contemporary textile artists were on show in Finland and abroad. Textile art had also become interesting commercially, especially in interior textiles of modern homes. The research uses sources of the Ornamo Association of Decorative Artists, for example the Ornamo year books published from 1927, the Finnish Society of Crafts and Design and the country s only school of applied arts, the Central School of Arts and Crafts and the Museum of Applied Arts maintained by the society and also the national specialist organisation the Friends of Finnish Handicraft. It also refers to the magazines Käsiteollisuus and Kotiliesi. The art historical dissertation studies the renaissance of weaving art of the inter-war years in Finland. It problematizes the relation of the succesfull and appreciated textile art to the concept of breakthrough of Modernism (Functionalism). With the material from textile artists activities it questions the prevailing idea of slow modernization of Finnish applied art and design and challenges the polarization of craft and industry in the discourses of Modernisms of design. The public discussions about modernization of design and applied art where textile art and especially the ryijy got sometimes into difficult positions are interpreted as power struggles. After taking independence in 1917 the Finnish tradition of ryijy rugs was set as a symbol of the original culture of the young nation. The research studies the development of the so called art ryijy and the notions and meanings of hand weaving in the national context and also in relation to contemporary events in international applied art and design. It highlights the continuity of hand crafted production of textiles and the strong position of textile artists working in this field. The research opens new perspectives to Finnish textile artists by showing their activities as entrepreneurs in their own weaving studios or design studios and referring to their many relations and functions as pattern designers and educators in the growing handicraft industries.

Difference covering arrays and pseudo-orthogonal Latin squares

A pair of Latin squares, A and B, of order n, is said to be pseudo-orthogonal if each symbol in A is paired with every symbol in B precisely once, except for one symbol with which it is paired twice and one symbol with which it is not paired at all. A set of t Latin squares, of order n, are said to be mutually pseudo-orthogonal if they are pairwise pseudo-orthogonal. A special class of pseudo-orthogonal Latin squares are the mutually nearly orthogonal Latin squares (MNOLS) first discussed in 2002, with general constructions given in 2007. In this paper we develop row complete MNOLS from difference covering arrays. We will use this connection to settle the spectrum question for sets of 3 mutually pseudo-orthogonal Latin squares of even order, for all but the order 146.

Rauta ja Ristilukki : Vilho Helasen salapoliisiromaanisarja

Vilho Helanen (1899 1952) was a right-wing opinion leader in interwar Finland. But following the Second World War, the political situation in the country changed dramatically, and Helanen lost his job as well as his influential social station. He began to write detective fiction, and between 1946 and 1952 published seven novels (one had already been published in 1941). The novels protagonist is Kaarlo Rauta, a lawyer who acts as a private investigator. This doctoral dissertation analyzes the Rauta series from three different points of view. It investigates the extent to which the author s life and his strong political background appears in the series. The study also situates the series within Finnish society during and after the war. Finally, the study examines the Rauta series in terms of the genre conventions of detective fiction, that is, the study compares the Rauta series with other Finnish crime fiction and international crime fiction written during the 1940s. The Iron and The Cross Spider uses the term citizenship education when analyzing how Helanen implicitly continued his political teaching when writing crime fiction. The series includes a didactic register, which instructs the middle class in appropriate behaviour and manners, and the social roles entailed by gender. A special area of focus in this didacticism are norms of correct masculinity and femininity. The study devotes specific attention to the status of character in the series. The masculine detective and his beautiful wife are prominent, as is the fictive community and the tensions that criss-cross it. After the war, the Rauta series takes on a positive tone. Men can earn their place in society by fighting at the front, and after the war a homosocial bond exists between all the former soldiers. Women are shut out of the war experience. The detective hero has served in the war, but he is physically and psychologically untouched by it. The community is threatened by artists and immoral bohemians, but not the working class. Artists have affairs outside of marriage and abnormal sexual habits. The members of the upper class are also described as immoral in the series. Sadistic sexuality is often characteristic of the criminals, who are mostly femme fatales in the fashion of hard-boiled detective stories and film noir. Also, strong feelings have a negative connotation in the series, and showing them is forbidden behaviour. Men become criminals when they are insufficiently masculine or when they have not carried out their duty by fighting in the war. Helanen portrayed the communists, his political opponents from the 1930s, as criminals in his post-war series, but they were not openly represented as Russians or communists. Instead, Helanen used the cross spider as their symbol, a symbol which the readers of the time would recognize.

"Det utspridda kärret; överallt och växande form" : Eva Wichmans novell "Kärret" som en prosamodernistisk berättelse om kvinnligt skapande

I min avhandling diskuterar jag om och hur man kan läsa Eva Wichmans novell "Kärret" (ur Molnet såg mig, 1942) som en prosamodernistisk berättelse om ett kvinnligt subjekt, och om kvinnligtskapande. Jag vill mot en prosamodernistisk bakgrund visa min tolkning med en stilistisk och entematisk analys. I min inledning markerar jag att forskare har haft svårt att avgöra vad Eva Wichman egentligen vill säga med "Kärret". De flesta definierar "Kärret" som en fabel, en moralisk berättelse. I min tolkning betonar jag att novellen kan läsas som en prosamodernistisk fabel om det kvinnliga skapandet. Eva Wichman har i många av sina verk beskrivit en kvinnlig konstnärs svårigheter i massamhället och den manliga världen. Jag anser därför att denna tolkning inte är långsökt då det gäller en naturallegori som "Kärret". Jag redovisar kort för bakgrunden till prosamodernismen; definierar stilistiska grundbegrepp i lyrikoch prosa samt diskuterar med hjälp av Peter Luthersson och Gunilla Domellöf hur den modernistiska individualiteten konstituerar sig i förhållande till samhället ochmoderniseringsprocessen. Jag tar fasta på den kvinnliga författarens skapandeprocess och poängterar, med hjälp av bl.a. Dominique Head och Domellöf, att det kvinnliga skapandet ofta är svårt att erhålla i ett traditionellt manligt samhälle. Head, Domellöf och Rachel Blau DuPlessis menar att det modernistiska skapandet hos kvinnor i stor grad sker med hjälp av stilistiska brott och luckor. I synnerhet förhållandet mellan metafor och metonymi utgör en viktig metod för den kvinnliga modernisten. I mitt tredje kapitel analyserar jag "Kärret" stilistiskt. Modernismen i "Kärret" går ut sammanställa motsatser och sinnesanalogier. Jag tar upp det lyriska och metaforiska i "Kärret"; upprepningar,parallellismer, rytm och dynamik, samt förhållandet mellan metaforer och metonymier utgående från en artikel av David Lodge. Jag demonstrerar i stilanalysen hur Eva Wichman bygger upp ett cykliskt mytiskt berättande. Detta cirkelberättande kan, enligt Domellöf, ses som en kvinnlig utmaning mot det traditionella manliga berättandet. Förhållandet mellan metaforer och metonymier spelar en stor roll också i min tematiska analys. Jag läser kärret i novellen som en symbol för ett kvinnlig subjekt. Kärret är uppbyggt av motsatser. Dessamotsatser kan ses som metaforer i min tolkning av kärret som kvinnligt subjekt. Motsatsparen yta/djup läser jag som den medvetna respektive undermedvetna nivån i det kvinnliga subjektet. Djupet, den undermedvetna nivån, analyserar jag delvis med hjälp av Julia Kristevas begrepp abjektet. Metaforerna spegel/öga ser jag som subjekt/objekt och manligt/kvinnligt i förhållande till det kvinnliga subjektet. Med hjälp av abjektet, omnipotens/känslighet, rörelse/statis samt liv/död visar jag hur Eva Wichman beskriver det konstnärliga skapandet, och den konstnärliga alieneringen i kontrast till det förtryckandet massamhället. Här baserar jag mig på Lutherssons resonemang om den modernistiska individualiteten. På så sätt drar jag slutsatsen att kärret som kvinnligt subjekt kan läsas som ett kvinnligt författarjag. "Kärret" är en berättelse om kvinnlig skaparkraft, om ett kvinnligt subjekt som skapar och verkar isamhället. Eva Wichman gestaltar det kvinnliga berättandet både tematiskt och språkligt. Därför är "Kärret" enligt mig inte en pessimistisk berättelse om ett "säkert nederlag" som många påstår, utan en storslagen fabel om ett modernistiskt subjekt i process.

High-Rate, Multisymbol-Decodable STBCs From Clifford Algebras

It is well known that space-time block codes (STBCs) obtained from orthogonal designs (ODs) are single-symbol decodable (SSD) and from quasi-orthogonal designs (QODs) are double-symbol decodable (DSD). However, there are SSD codes that are not obtainable from ODs and DSD codes that are not obtainable from QODs. In this paper, a method of constructing g-symbol decodable (g-SD) STBCs using representations of Clifford algebras are presented which when specialized to g = 1, 2 gives SSD and DSD codes, respectively. For the number of transmit antennas 2(a) the rate (in complex symbols per channel use) of the g-SD codes presented in this paper is a+1-g/2(a-9). The maximum rate of the DSD STBCs from QODs reported in the literature is a/2(a-1) which is smaller than the rate a-1/2(a-2) of the DSD codes of this paper, for 2(a) transmit antennas. In particular, the reported DSD codes for 8 and 16 transmit antennas offer rates 1 and 3/4, respectively, whereas the known STBCs from QODs offer only 3/4 and 1/2, respectively. The construction of this paper is applicable for any number of transmit antennas. The diversity sum and diversity product of the new DSD codes are studied. It is shown that the diversity sum is larger than that of all known QODs and hence the new codes perform better than the comparable QODs at low signal-to-noise ratios (SNRs) for identical spectral efficiency. Simulation results for DSD codes at variousspectral efficiencies are provided.

Comparison Of If Estimation Methods For Noise Robustness

Non-stationary signal modeling is a well addressed problem in the literature. Many methods have been proposed to model non-stationary signals such as time varying linear prediction and AM-FM modeling, the later being more popular. Estimation techniques to determine the AM-FM components of narrow-band signal, such as Hilbert transform, DESA1, DESA2, auditory processing approach, ZC approach, etc., are prevalent but their robustness to noise is not clearly addressed in the literature. This is critical for most practical applications, such as in communications. We explore the robustness of different AM-FM estimators in the presence of white Gaussian noise. Also, we have proposed three new methods for IF estimation based on non-uniform samples of the signal and multi-resolution analysis. Experimental results show that ZC based methods give better results than the popular methods such as DESA in clean condition as well as noisy condition.

Syntactic Approach to ECG Rhythm Analysis

A diagnostic system for ECG rhythm monitoring based on syntactic approaches to pattern recognition is presented here. The method proposed exploits the difference in shape and structure between arrhythmic and normal ECG patterns to generate distinctly different descriptions in terms of a chosen set of primitives. A given frame of signal is first approximated piecewise linearly into a set of line segments which are completely specified in terms of their length and slope values. The slope values are quantized into seven distinct levels and a unit-length line segment with a slope value in each of these levels is coded as a slope symbol. Seven such slope symbols constitute the set of primitives. The given signal is represented as a string of such symbols based on the length and angle of the line segments approximating the signal. Context-free languages are used for describing the classes of abnormal and normal ECG patterns considered here. Analysis of actual ECG data shows efficiency comparable with that of existing methods and a saving in processing time.

Clinical Escherichia coli isolates utilize alpha-hemolysin to inhibit in vitro epithelial cytokine production

Uropathogenic Escherichia coli is the primary cause of urinary tract infections, which affects over 60% of women during their lifetime. UPEC exhibits a number of virulence traits that facilitate colonization of the bladder, including inhibition of cytokine production by bladder epithelial cells. The goal of this study was to identify the mechanism of this inhibition. We observed that cytokine suppression was associated with rapid cytotoxicity toward epithelial cells. We found that cytotoxicity, cytokine suppression and alpha-hemolysin production were all tightly linked in clinical isolates. We screened a UPEC fosmid library and identified clones that gained the cytotoxicity and cytokine-suppression phenotypes. Both clones contained fosmids encoding a PAI II(J96)-like domain and expressed the alpha-hemolysin (hlyA) encoded therein. Mutation of the fosmid-encoded hly operon abolished cytotoxicity and cytokine suppression. Similarly, mutation of the chromosomal hlyCABD operon of UPEC isolate F11 also abolished these phenotypes, and they could be restored by introducing the PAI II(J96)-like domain-encoding fosmid. We also examined the role of alpha-hemolysin in cytokine production both in the murine UTI model as well as patient specimens. We conclude that E. coli utilizes alpha-hemolysin to inhibit epithelial cytokine production in vitro. Its contribution to inflammation during infection requires further study.

Kemian ylioppilaskokeen tehtävät summatiivisen arvioinnin välineenä

The main purpose of the research was to illustrate chemistry matriculation examination questions as a summative assessment tool, and represent how the questions have evolved over the years. Summative assessment and its various test item classifications, Finnish goal-oriented curriculum model, and Bloom’s Revised Taxonomy of Cognitive Objectives formed the theoretical framework for the research. The research data consisted of 257 chemistry questions from 28 matriculation examinations between 1996 and 2009. The analysed test questions were formulated according to the national upper secondary school chemistry curricula 1994, and 2003. Qualitative approach and theory-driven content analysis method were employed in the research. Peer review was used to guarantee the reliability of the results. The research was guided by the following questions: (a) What kinds of test item formats are used in chemistry matriculation examinations? (b) How the fundamentals of chemistry are included in the chemistry matriculation examination questions? (c) What kinds of cognitive knowledge and skills do the chemistry matriculation examination questions require? The research indicates that summative assessment was used diversely in chemistry matriculation examinations. The tests included various test item formats, and their combinations. The majority of the test questions were constructed-response items that were either verbal, quantitative, or experimental questions, symbol questions, or combinations of the aforementioned. The studied chemistry matriculation examinations seldom included selected-response items that can be either multiple-choice, alternate choice, or matching items. The relative emphasis of the test item formats differed slightly depending on whether the test was a part of an extensive general studies battery of tests in sciences and humanities, or a subject-specific test. The classification framework developed in the research can be applied in chemistry and science education, and also in educational research. Chemistry matriculation examinations are based on the goal-oriented curriculum model, and cover relatively well the fundamentals of chemistry included in the national curriculum. Most of the test questions related to the symbolism of chemical equation, inorganic and organic reaction types and applications, the bonding and spatial structure in organic compounds, and stoichiometry problems. Only a few questions related to electrolysis, polymers, or buffer solutions. None of the test questions related to composites. There were not any significant differences in the emphasis between the tests formulated according to the national curriculum 1994 or 2003. Chemistry matriculation examinations are cognitively demanding. The research shows that the majority of the test questions require higher-order cognitive skills. Most of the questions required analysis of procedural knowledge. The questions that only required remembering or processing metacognitive knowledge, were not included in the research data. The required knowledge and skill level varied slightly between the test questions in the extensive general studies battery of tests in sciences and humanities, and subject-specific tests administered since 2006. The proportion of the Finnish chemistry matriculation examination questions requiring higher-order cognitive knowledge and skills is very large compared to what is discussed in the research literature.
