Big band -sovitus kappaleesta "(Surrounded by) Zip-Zip" : Sovituksen analysoiminen puhallinsektioiden näkökulmasta

Opinnäytetyö käsittelee big bandia sekä sille sovittamista. Keskityn tarkastelemaan ennen kaikkea 1930-40-lukujen musiikillista murrosta, jolloin syntyi uusi tapa käsitellä useasti suurimpien orkestereiden kokoonpanoon kuuluneita puhaltimia. Tuona ajanjaksona orkestereiden puhallinryhmistä sekä komppisoittimista alettiin yleisesti muodostaa sektioita. Tämä kokoonpano sai nimekseen ”big band”. Opinnäytetyön tavoitteena oli syventää tietojani big bandin puhallinsektioiden toiminnasta sekä niiden yleisimmistä tehtävistä. Tehtäviä selventääkseni tein big band -sovituksen omasta kappaleestani, missä peilasin 1930-40-luvuilla yleistynyttä tyyliä sovittaa. Sovitustyön valmistuminen pohjautui kolmeen seikkaan: historian tuntemus, sovitussuunnitelman teko sekä musiikin teorian tuntemus. Historian tuntemus loi pohjan sovitussuunnitelmalle, minkä avulla loin kehykset sovitustyön tekemiselle. Sovituksen tekninen suoritus sekä valmistuminen pohjautuivat musiikin teorian ymmärtämiseen sekä kokemukseeni sovittajana. Sovitukseni analyysi-osiossa käyn sovituksen läpi osa kerrallaan, selventäen kuinka puhallinsektiot kussakin osassa toimivat. Opinnäytetyön suunnittelu sekä tiukka rajaus eivät poissulkeneet täysin aiheen moniulotteisuutta. Pelkkiin puhallinsektioihin keskittyminen aiheutti ongelmallisia tilanteita, jotka vaativat suurien kompromissien tekemistä. Muun muassa teorian ja reharmonisoinnin syvempi analysoiminen tässä jää tekemättä. Sovituksellisten sekä soinnullisien ratkaisuiden olemassaolo vaatisi yleensä rinnalleen syvempää perustelua. Näin varsinkin nyt, kun ratkaisut harmoniassa ovat aika ajoin jopa radikaaleja. Tulin kuitenkin siihen päätelmään, että kaikki tekstissä ilmenevä tieto mikä ei koskisi puhallinsektioiden käyttäytymistä olisi irrelevanttia. Lopputuloksen oli tarkoitus olla jäsennelty esittely siitä, mitä big bandin puhallinsektiot ovat ja tekevät. Käyn opinnäytteessäni lyhyesti läpi myös sovitukseni esikuvat. Tämä lyhyt historia-osuus kertoo tiivistetysti mistä ajalta mallintamani sovitustyyli on peräisin ja ketkä ovat edesauttaneet sen yleistymisessä. Historia osuus toimii mainiosti suppeana avainsanastona aiheesta enemmän kiinnostuneelle.

Concepts and Reference. Defending a Dual Theory of Natural Kind Concepts

In this thesis I argue that the psychological study of concepts and categorisation, and the philosophical study of reference are deeply intertwined. I propose that semantic intuitions are a variety of categorisation judgements, determined by concepts, and that because of this, concepts determine reference. I defend a dual theory of natural kind concepts, according to which natural kind concepts have distinct semantic cores and non-semantic identification procedures. Drawing on psychological essentialism, I suggest that the cores consist of externalistic placeholder essence beliefs. The identification procedures, in turn, consist of prototypes, sets of exemplars, or possibly also theory-structured beliefs. I argue that the dual theory is motivated both by experimental data and theoretical considerations. The thesis consists of three interrelated articles. Article I examines philosophical causal and description theories of natural kind term reference, and argues that they involve, or need to involve, certain psychological elements. I propose a unified theory of natural kind term reference, built on the psychology of concepts. Article II presents two semantic adaptations of psychological essentialism, one of which is a strict externalistic Kripkean-Putnamian theory, while the other is a hybrid account, according to which natural kind terms are ambiguous between internalistic and externalistic senses. We present two experiments, the results of which support the strict externalistic theory. Article III examines Fodor’s influential atomistic theory of concepts, according to which no psychological capacities associated with concepts constitute them, or are necessary for reference. I argue, contra Fodor, that the psychological mechanisms are necessary for reference.

Den talande bokens poetik : en studie med fokus på olika unga vuxnas reception av tre fiktiva texter inlästa på band

The purpose of the research project The poetics of the talking book is to contribute to the knowledge about patterns of understanding in young adults’ reception of fiction, which they listened to through audio books. The problem explored was: How do different groups of listeners receive fictive text presented as a talking book with variations regarding use of voice, engagement and sound effects? The problem formulation rendered four specific research questions: 1. What patterns can be identified in the listeners’ answers regarding story structure and cognitive content in a comparative perspective comprising different reading styles in the taped versions of the text? 2. What patterns of understanding in interpretative reading can be identified in different listeners? 3. Which thoughts do the listeners have about what the talking book should sound like? 4. What affordances for young adults with the functional disability of mild mental retardation can be made visible through guided literature conversations? The theoretical frame of reference was formed by text–reader-oriented literary theory, psychological schema theory, and research regarding voice quality and communication. The project was carried out in two steps. The first phase was to produce the audio books with two variations of reading practice of three short stories with an existential theme in each text. The second step comprised interviewing of 32 young adults (a special group with a reading handicap in form of mild mental retardation, and a reference group with no handicap). The interviews formed as literary conversation were carried out three times during one year. The phenomenological-hermeneutic approach focused on the life worlds of the participants as meaning seeking beings. The analysis was carried out using method triangulation, mainly using phenomenological meaning concentration. The double hermeneutics in use when interpreting the interpretations of the participants revealed a capacity for aesthetic reading of fiction in the special group as well as in the reference group. The aesthetic qualities were found sufficient in all variations of reading by the professional readers of the audio book they listened to. The young adults also could describe how they wanted the audio book to sound: just as if you were reading yourself. A model describing the analytical steps and concepts in use was a result that can serve as an outline of a poetics for the talking book. Unexpected research results were how important the guided literary conversation turned out to be in order to realise the affordances given by the texts regarding exploration of existential themes in the young adults’ life worlds. Thus the result of the research project can be positioned as a piece of emancipatory research stressing the importance of including this group of young adults in the society’s conversation about culture and meaning.

Formation of polyelectrolyte multilayers and polyelectrolyte complexes in dual polymer treatment of papermaking pulp

The goal of this study was to find a new approach to modify chemically the properties of paper by improving fiber quality. This Master’s thesis includes the multiple polymer treatment in general and themeasurement methods with which the formation of multilayers and complexes can be noticed. The treatment by an oppositely charged dual polymer system is a good approach to increase paper strength. In this work, starch, a cationic polymer, and carboxymethyl cellulose (CMC), an anionic polymer, were used step-by-step to improve paper strength. The adsorption of cationic starch and CMC on cellulose fibers were analyzed via polyelectrolyte titration. The results showed that paper strength was enhanced slightly with a layer-by-layer assembly of the polymers. However, if the washing stage, which was required for layer-by-layer assembly, was eliminated, the starch/CMC complex was deposited on fibers more efficiently, and the paper strength was improved more significantly.

The Dual Role of HIF Hydroxylase PHD3 in Cancer Cell Survival

Most advanced tumours face periods of reduced oxygen availability i.e. hypoxia. During these periods tumour cells undergo adaptive changes enabling their survival under adverse conditions. In cancer hypoxia-induced cellular changes cause tumour progression, hinder cancer treatment and are indicative of poor prognosis. Within cells the main regulator of hypoxic responses is the hypoxia-inducible factor (HIF). HIF governs the expression of over a hundred hypoxia-inducible genes that regulate a number of cellular functions such as angiogenesis, glucose metabolism and cell migration. Therefore the activity of HIF must be tightly governed. HIF is regulated by a family of prolyl hydroxylase enzymes, PHDs, which mark HIF for destruction in normoxia. Under hypoxic conditions PHDs lose much of their enzymatic activity as they need molecular oxygen as a cofactor. Out of the three PHDs (PHD1, 2 and 3) PHD2 has been considered to be the main HIF-1 regulator in normoxic conditions. PHD3 on the other hand shows the most robust induction in response to oxygen deprivation and it has been implied as the main HIF-1 regulator under prolonged hypoxia. SQSTM1/p62 (p62) is an adaptor protein that functions through its binding motifs to bring together proteins in order to regulate signal transduction. In non-stressed situations p62 levels are kept low but its expression has been reported to be upregulated in many cancers. It has a definitive role as an autophagy receptor and as such it serves a key function in cancer cell survival decisions. In my thesis work I evaluated the significance of PHD3 in cancer cell and tumour biology. My results revealed that PHD3 has a dual role in cancer cell fate. First, I demonstrated that PHD3 forms subcellular protein aggregates in oxygenated carcinoma cells and that this aggregation promotes apoptosis induction in a subset of cancer cells. In these aggregates an adaptor protein SQSTM1/p62 interacts with PHD3 and in so doing regulates PHD3 expression. SQSTM1/p62 expression is needed to keep PHD3 levels low in normoxic conditions. Its levels rapidly decrease in response to hypoxia allowing PHD3 protein levels to be upregulated and the protein to be diffusely expressed throughout the cell. The interaction between PHD3 and SQSTM1/p62 limits the ability of PHD3 to function on its hydroxylation target protein HIF-1alpha. Second, the results indicate that when PHD3 is upregulated under hypoxia it protects cancer cells by allowing cell cycle to proceed from G1 to S-phase. My data demonstrates that PHD3 may either cause cell death or protect the cells depending on its expression pattern and the oxygen availability of tumours.

Dual light barrier method for six degrees of freedom tool center point calibration of an industrial robot

Tool center point calibration is a known problem in industrial robotics. The major focus of academic research is to enhance the accuracy and repeatability of next generation robots. However, operators of currently available robots are working within the limits of the robot´s repeatability and require calibration methods suitable for these basic applications. This study was conducted in association with Stresstech Oy, which provides solutions for manufacturing quality control. Their sensor, based on the Barkhausen noise effect, requires accurate positioning. The accuracy requirement admits a tool center point calibration problem if measurements are executed with an industrial robot. Multiple possibilities are available in the market for automatic tool center point calibration. Manufacturers provide customized calibrators to most robot types and tools. With the handmade sensors and multiple robot types that Stresstech uses, this would require great deal of labor. This thesis introduces a calibration method that is suitable for all robots which have two digital input ports free. It functions with the traditional method of using a light barrier to detect the tool in the robot coordinate system. However, this method utilizes two parallel light barriers to simultaneously measure and detect the center axis of the tool. Rotations about two axes are defined with the center axis. The last rotation about the Z-axis is calculated for tools that have different width of X- and Y-axes. The results indicate that this method is suitable for calibrating the geometric tool center point of a Barkhausen noise sensor. In the repeatability tests, a standard deviation inside robot repeatability was acquired. The Barkhausen noise signal was also evaluated after recalibration and the results indicate correct calibration. However, future studies should be conducted using a more accurate manipulator, since the method employs the robot itself as a measuring device.
